Body 20 has forelimb linkage mechanism 70 which interlocks hind leg link material 88 which interlocks rocking of hind legs 40, and rotation of handle member 60, and rocking of forelimb 30 and rotation (rotation of arm member 25 which supports handle member 60) of handle member 60.
In stroller 10 of such this embodiment, An operator (for example, infants' guardian) grasps handle member 60, and controls stroller 10, and as the forelimb 30 side of stroller 10 serves as the front of a direction of movement, it can make it run stroller 10 in the state where infants were made to take sheet 130.
stroller 10 and body 20 are received in this detailed in the letter one -- "-- front" -- "-- back" -- "-- upper" -- "-- a term of lower", the "direction of order", and the "up-and-down direction", it was based on an operator who controls stroller 10 in a deployment state when there were no directions in particular -- "-- front" -- "-- back" -- "-- upper" -- "-- lower", the "direction of order", and the "up-and-down direction" are meant. In detail, it is aimed to connect the lower left and the upper right of space in Drawing 1 to the "direction of order" of stroller 10, and corresponds in the direction of right and left of space in Drawing 2. And as long as there are no directions in particular, a "front" is a side which an operator who controls stroller 10 turns to, and left-hand side of space in the lower left side of space in Drawing 1 and Drawing 2 becomes a front side of stroller 10. On the other hand, while intersecting perpendicularly in the direction of order, it aims to intersect perpendicularly with the "up-and-down direction" of stroller 10 at sidewall. Therefore, when sidewall is the level surface, the "up-and-down direction" puts perpendicularly. The "cross direction" or the "cross direction" is a transverse direction, and it aims to intersect perpendicularly with both the "direction of order", and the "up-and-down direction. "
First, body 20 of stroller 10 is explained. Body 20 of stroller [in / as mainly shown in Drawings 1-9 / this embodiment] 10, More specifically, core member 25, forelimb 30, hind legs 40, arm member 30, and handle member 60 have in general symmetrical composition centering on a field which met in the direction before and after passing along a center in the cross direction.
As shown in Drawing 1 - Drawing 4, in body 20 of stroller 10 of a deployment state, core member 25 is arranged in general at the center. As mainly shown in Drawing 6, Drawing 9, Drawing 10, and Drawing 11, core member 25 has base part 26 as a body part, and forelimb pivotal supporting part 27 removably fixed to base part 26 via fixed implement 25a. Base part 26 of core member 25 consists of an aluminum forging, for example, and has high rigidity. Forelimb pivotal supporting part 27 constitutes forelimb unit 29 with supported forelimb 30 so that it may be a member supported rotatably and forelimb 30 may be mentioned below.
Next, forelimb 30 and hind legs 40 which were connected to core member 25 are explained.
A pair of forelimbs 30 put in order and arranged by the cross direction are provided in body 20 illustrated in Drawing 1 - Drawing 9. In a deployment state, as shown in Drawing 3, as each forelimb 30 was located in back in the direction of order, it was prolonged from core member 20 and has fallen rather than a near end where, as for the end concerned, an end of a side connected with core member 25 is connected with front wheel unit 35 of the side opposite to. estrangement [in / in / as shown in Drawing 1 and Drawing 2 / condition of use / in a pair of forelimbs 30 / the cross direction] -- an interval estranges from the core member 25 side -- it inclines so that it is alike, it may take and it may become large.
Caster 34 is attached to a lower end of each forelimb 30 as mentioned above. Caster 34 is supporting a pair of front wheels 35 rotatably. Caster 34 is supporting an axle of a pair of front wheels 35 so that revolution is possible. a pair of preceding cars supported by lower end of each forelimb 30 in body 20 of stroller 10 shown in Drawing 1 - Drawing 7 -- estrangement of ring 35 -- an interval -- estrangement of a lower end of a pair of forelimbs 30 -- as compared with an interval, it is very small. Therefore, it can be said that it is constituted as a four-wheeled vehicle if stroller 10 by this embodiment shown in Drawing 1 - Drawing 7 is classified functionally.
To core member 25, each forelimb 30 is connected so that rotation is possible (rocking is possible). As shown in Drawing 8, it is rotation axis (rocking axis) raf of each forelimb 30, It has extended so that the cross direction outside (side estranged from the center of body 20 of stroller 10 in the cross direction) may be located in back in the direction of order rather than a cross direction inner side (side close to the center of body 20 of stroller 10 in the cross direction). For this reason, from a state (state shown in Drawing 1 - Drawing 4) which prolonged for it and came out of core member 25 to the front [in / in each forelimb 30 / the direction of order], and a method of the outside in the cross direction, To the state (state shown in Drawing 5 and Drawing 6) where extended below in general and it fell from core member 25, it can rock to core member 25. As shown in Drawing 6, rotation axis (rocking axis) raf of each forelimb 30 is prolonged so that the cross direction outside may be located in a lower part in the up-and-down direction rather than a cross direction inner side. As a result, even if each forelimb 30 rotates to core member 25, a posture whose front wheel 35 supported under the forelimb 30 is almost parallel before rotating can be maintained. That is, also in the state where rotated forelimb 30 to core member 25, and it folded up, an axis-of-rotation line of a pair of front wheels 35 supported by each forelimb 30 via caster 34 comes to be prolonged in sidewall and parallel so that it may be shown figure 6.
Next, hind legs 40 are explained. A pair of hind legs 40 put in order and arranged by the cross direction as well as forelimb 30 are provided in body 20 illustrated in Drawing 1 - Drawing 7. In a deployment state, as shown in Drawing 3, as each hind leg 40 was located ahead in the direction of order, it was prolonged from core member 20 and has fallen rather than a near end where, as for the end concerned, an end of a side connected with core member 25 is connected with rear wheel unit 45 of the side opposite to. estrangement [in / in / as shown in Drawing 4 / condition of use / in a pair of hind legs 40 / the cross direction] -- an interval estranges from the core member 25 side -- it inclines so that it is alike, it may take and it may become large.
To core member 25, each hind leg 40 is connected so that rotation is possible (rocking is possible). As shown in Drawing 8, rotation axis (rocking axis) rar1 of each hind leg 40 and rar2 are prolonged so that the cross direction outside may be located ahead in the direction of order rather than a cross direction inner side. For this reason, from a state (state shown in Drawing 1 - Drawing 4) which prolonged for it and came out of core member 25 to back [in / in each hind leg 40 / the direction of order], and a method of the outside in the cross direction, To the state (state shown in Drawing 5 and Drawing 6) where extended below in general and it fell from core member 25, it can rock to core member 25.
Rear wheel career 50 is attached to a lower end of each hind leg 30. Rear wheel career 50 is supporting rear wheel unit 35 with back wheel 35. Rear wheel career 50 and rear wheel unit 35 are explained in full detail behind.
In body 20 of illustrated stroller 10, each hind leg 40 contains the 1st hind leg element 41 and the 2nd hind leg element 42 which are arranged in parallel. As shown in Drawing 9, the 1st hind leg element 41 and the 2nd hind leg element 42 are connected with core member 25 focusing on parallel rotation axis (rocking axis) rar1 and rar2 in the upper end. In the lower end, the 1st hind leg element 41 and the 2nd hind leg element 42 are connected with career support member 43 which supports rear wheel career 50 focusing on parallel rotation axis (rocking axis) rar3 and rar4 so that rotation is possible (rocking is possible) (refer to Drawing 18). Rotation axis rar1 to core member 25 of hind leg elements 41 and 42 and rar2, rotation axis rar3 to career support member 43 of hind leg elements 41 and 42, rar4, and は -- as it is parallel and is typically shown in Drawing 9, these rotation axis rar1, rar2, rar3, and rar4 are arranged in a position which forms a parallelogram. As a result, even if each hind leg 40 rotates to core member 25, a posture whose back wheel 47 supported under the hind legs 40 is almost parallel before rotating can be maintained. That is, also in the state where rotated hind legs 40 to core member 25, and it folded up, an axis-of-rotation line of back wheel 47 supported by each hind leg 40 via rear wheel career 50 comes to be prolonged in sidewall and parallel so that it may be shown figure 7.
As shown in Drawing 5 - Drawing 7, it sets on stroller 10 of this embodiment, When folding up from condition of use and changing into a state, forelimb 30 of left-hand side which extends and comes out of core member 25, right-hand side forelimb 30, left-hand side hind legs 40, and right-hand side hind legs 40 are rocked to core member 25 so that it may approach mutually. In other words, left-hand side forelimb 30, right-hand side forelimb 30, left-hand side hind legs 40, and right-hand side hind legs 40 are rocked to core member 25 so that an angle made while it is mutual may become small. In other words, a pair of forelimbs 30 and a pair of hind legs 40 are rocked to core member 25 so that an end of a side estranged from the core member 25 may be arranged in a mutually near position.
As a result, as shown in Drawing 5, in a fold-up state, forelimb 30 and hind legs 40 approach mutually, and prolong for it and appear from core member 25 in a lower part. Thereby, a size in the direction of stroller 10 order can be miniaturized in a fold-up state. As shown in Drawing 6, in a fold-up state, a pair of forelimbs 30 approach mutually, and prolong for it and appear from core member 25 in a lower part. Similarly, as shown in Drawing 7, in a fold-up state, a pair of hind legs 40 approach mutually, and prolong for it and appear from core member 25 in a lower part. Thereby, a size in the cross direction of stroller 10 can be miniaturized in a fold-up state.
Next, handle member 60 and arm member 65 are explained.
As shown in Drawings 1-7 that it will mention above, handle member 60 is connected with core member 25 via a pair of arm members 65 put in order and arranged at the cross direction so that rocking is possible. Handle member 60 has a pair of handle section extending 61 put in order and arranged at the cross direction, and flection 62 which connects between a pair of handle section extending 61 and which can be crooked. In this embodiment, one end of handle section extending 61 is connected to arm member 25 so that rotation is possible (rocking is possible), and the other end of handle section extending 61 is connected to flection 62.
As shown, for example in Drawing 3 and Drawing 4, a near field of arm member 25 of handle section extending 61 is connected with an end of hind leg link material 88 so that rotation is possible. The other end of hind leg link material 88 is connected with the 2nd hind leg element 42 of hind legs 40 in a near field of career support member 43. This hind leg link material 88 comes to interlock rotation to core member 25 of hind legs 40, and rotation of a pair of handle section extending 61. And as shown in Drawing 5, in the state where it folded up, handle member 60 comes to be prolonged towards a lower part from arm member 35 supported on core member 25.
That is, when folding up from condition of use and changing into a state, handle member 60 and hind legs 40 are rocked to core member 25 so that it may approach mutually. In other words, handle member 60 and hind legs 40 are rocked to core member 25 so that an angle made in side view while it is mutual may become small. In other words, handle member 60 and hind legs 40 are rocked so that an end of a side estranged from arm member 65 of handle member 60 and an end estranged from core member 25 of hind legs 40 may be arranged in a mutually near position.
by the way, it mentioned above -- as -- estrangement to the cross direction of a near end of career support member 43 of a pair of hind legs 40 -- when folding up an interval from condition of use and changing into a state, it comes (refer to Drawing 4 and Drawing 7) to approach. estrangement to the cross direction of a pair of hind legs 40 -- estrangement to the cross direction of a pair of hind leg link material 88 connected to a pair of hind legs 40, respectively when an interval became narrow -- an interval also becomes narrow. And in this embodiment, a pair of handle section extending 60 approaches mutually with approach to the cross direction of a pair of hind legs 40, and approach to the cross direction of a pair of hind leg link material 88, Arm member 65 which supports handle member 60 and handle member 60 is constituted as follows.
First, each arm member 65 has rotation base 66 connected to core member 25 so that rotation was possible (rocking is possible), and handle support member 67 which is supported by rotation base 66 and connected with handle member 60. Handle support member 67 is connected with an end of handle section extending 61 of handle member 60 so that rotation is possible.
Rotation axis ram to core member 25 of each rotation base 66 intersects the cross direction, and is suitable in the direction of order in general (for example, refer to Drawing 3 and Drawing 13). for this reason, estrangement [in / arm members / a pair of / 65 / in core member 25 of a pair of arm members 65 / the cross direction between ends of the side opposite to (i. e., between handle support members 67) ] -- it can rotate to core member 25 so that an interval may change.
Handle support member 67 can be rotated to rotation base 66 focusing on axis ras parallel to rotation axis ram to core member 25 of rotation base 66 (for example, refer to Drawing 13). Therefore, arm member 65 is while maintaining rotation axis rah (refer to Drawing 4) of a pair of handle support members 67, and corresponding handle section extending 61 at a horizontally parallel straight line, It receives core member 25, and it can rotate and can make the cross direction approach or estrange a pair of handle support members 67. estrangement in the cross direction between ends of a side which approaches arm member 65 of a pair of handle section extending 61 with approach to the cross direction of hind legs 40 by composition of such an arm member 65 -- an interval can be folded up and it can narrow in a state.
As mentioned above, an end of a side estranged from arm member 65 of a pair of handle section extending 61 is connected by flection 62 which can be crooked. estrangement in the cross direction between ends of a side estranged by this flection 62 folding up and being crooked in a state from arm member 65 of a pair of handle section extending 61 -- an interval can be narrowed.
In the state where composition of the above arm member 65 and handle member 60 folded up, handle member 60 and hind legs 40 are from condition of use, An end of a side estranged from arm member 65 of handle member 60 and an end estranged from core member 25 of hind legs 40 come to be arranged in a position which approached mutually not only the direction of order but the cross direction.
As shown in Drawing 17, flection 62 has the 2nd flection arranged between the 1st flection 63a and the 3rd flection 63c which were connected to an end of a side estranged from arm member 65 of a pair of handle section extending 62, and the 1st flection 63a and the 3rd flection 63c. As for the 1st - the 3rd flection 63a, 63b, and 63c, between ends is connected so that rotation is possible respectively.
And as shown in Drawing 1 - Drawing 4, flection 62 has prolonged for it and come out of a pair of handle section extending 61 in condition of use towards a side estranged from arm member 65. Flection 62 is crooked in a fold-up state so that it may project to a side close to arm member 65, as well shown in Drawing 7 on the other hand. Thereby, as shown in Drawing 17, in a fold-up state, a size of a handle member can be miniaturized at the cross direction not only in a direction but in the up-and-down direction and the direction of order. Namely, a size of handle member 60 at the time of folding can be simultaneously miniaturized not only in the cross direction but in the direction of order, maintaining a size in condition of use of handle member 60 to suitable length in consideration of maneuverability drivability etc.
As shown in Drawing 5, bending-axis line ba of flection 62 lies at right angles to plane vp of imagination in which a pair of handle section extending 61 is contained substantially. Therefore, as shown in Drawing 5, projection amount pl of flection 62 from plane vp of imagination in which a pair of handle section extending 61 is contained does not become large substantially rather than condition of use in a fold-up state. It becomes possible also from this point to fold up stroller 10 and to miniaturize a size in a state effectively in the direction of order, and the up-and-down direction.
In body 20 of stroller 10 by this embodiment, forelimb linkage mechanism 70 is provided between a pair of arm members 20, and forelimb 30 as well shown in Drawing 10 and Drawing 11. Forelimb linkage mechanism 70 connects between a pair of arm members 20, and forelimbs 30, and it is constituted so that rocking of forelimb 30 and rotation of a pair of arm members 65 may be interlocked.
As shown in Drawing 10 and Drawing 11, forelimb linkage mechanism 70 is, It has arm member connecting linkage 72 which connects between a pair of arm members 65, forelimb connecting linkage 78 which connects between a pair of forelimbs 30, and connection link 81 prolonged in between arm member connecting linkage 72 and forelimb connecting linkages 78.
As shown in Drawing 10, arm member connecting linkage 72 is horizontally prolonged in the shape of a straight line in condition of use in between rotation bases 66 of a pair of arm members 65. In that central portion, this arm member connecting linkage 72 is constituted so that crookedness is possible, while being connected to rotation base 66 so that rotation is possible. Therefore, when it folds up from condition of use and a pair of rotation bases 66 rotate to core member 25 towards a state, arm member connecting linkage 72 is crooked with approach of a pair of rotation bases 66.
As shown in Drawing 13, in this embodiment, bending-axis line bal1 of arm member connecting linkage 72 and rotation axis ral1 to rotation base 66 of arm member connecting linkage 72 are especially prolonged almost in parallel with rotation axis ram to core member 25 of rotation base 66. For this reason, arm member connecting linkage 72 can be smoothly crooked with rotation to core member 25 of rotation base 66.
However, arm member connecting linkage 72 and connection link 81 are connected via the 1st connector 73. And the 1st connector 73 has been arranged on arm member connecting linkage 72, and has regulated that arm member connecting linkage 72 is crooked as the forelimb 30 side projects (it projects to the down side). For this reason, as shown in Drawing 11, arm member connecting linkage 72 is crooked so that a central portion may project towards the upper part, and is not crooked in a reverse side.
Similarly, as shown in Drawing 10, forelimb connecting linkage 78 is horizontally prolonged in the shape of a straight line in between a pair of forelimbs 30 in condition of use. In that central portion, this forelimb connecting linkage 78 is constituted so that crookedness is possible, while being connected to forelimb 30 so that rotation is possible. Therefore, when it folds up from condition of use and a pair of forelimbs 30 rotate to core member 25 towards a state, forelimb connecting linkage 78 is crooked with approach of a pair of forelimbs 30.
Connection link 81 is connected near a part of arm member connecting linkage 72 which can be crooked, or the part which can be crooked via the 1st connector 73, as mentioned above. As for connection link 81, the end is connected to the 1st connector 73 so that rotation is possible (rocking is possible). Rotation axis rac1 to the 1st connector 73 of connection link 81 lies at right angles to bending-axis line bal1 of arm member connecting linkage 72 so that I may be understood from Drawing 11 and Drawing 13. As shown in Drawing 10 and Drawing 11, connection link 81 is connected near a part of forelimb connecting linkage 78 which can be crooked, or the part which can be crooked via the 2nd connector 79. The other end with connection link 81 contrary to one end connected to the 1st connector 73 is connected to the 2nd connector 79 so that rotation is possible (rocking is possible). [one] As shown in Drawing 11, rotation axis rac2 to the 2nd connector 79 of connection link 81 lies at right angles to bending-axis line bal2 of forelimb connecting linkage 78.
By the way, body 20 of stroller 10 in this embodiment is provided with a mechanism for maintaining condition of use, i. e., the state where it was developed. A state maintenance mechanism is constituted so that displacement or modification of an element which makes body 20 of stroller 10 may be regulated, so that it may explain below. As mentioned above, displacement or modification of an element which makes body 20 of stroller 10 is interlocking via forelimb linkage mechanism 40 and hind leg link material 88. Therefore, if displacement or modification of one component is regulated according to a state maintenance mechanism, it will become possible to regulate folding operation of stroller 10 and to maintain stroller 10 to condition of use.
First, a mechanism which regulates rotation of handle member 60 to arm member 65 as 1st state maintenance mechanism 91 is established. As shown in Drawing 15 and Drawing 16, 1st state maintenance mechanism 91 is, It is constituted so that regulation slider 92 arranged in end 61a by the side of arm member 65 of handle section extending 61 and slot 68 formed in handle support member 67 of arm member 56 which meets end 61a of handle section extending 61 may be included.
Regulation slider 92 includes a pair of regulation projections 92a projected from end 61a of handle section extending 61 towards handle support member 67 of arm member 56 which meets this end 61a. In handle section extending 61, regulation slider 92 is slidable to handle section extending 61. Regulation slider 61 is energized towards a side estranged from the flection 62 side in handle section extending 61 with compression spring 93b provided in handle section extending 61. With the 1st changeover switch 64 provided in an end field at the flection 62 side of each handle section extending 61, regulation slider 61 can resist energizing force of compression spring 93b, and can move now. The 1st changeover switch 64 is slidably provided on the external surface of handle section extending 61 to handle section extending 61. In handle section extending 61, connecting member 93b which connects the 1st changeover switch 64 and regulation slider 92 is prolonged.
Slot 68 formed in handle support member 67 on the other hand, It has regulation slot 68b in which regulation projection 92a of regulation slider 92 moved by energization from compression spring 93b is stored, and guide rail 68a which it shows to regulation projection 92a of regulation slider 92 resisted and moved to energization from compression spring 93b. It extended and regulation slot 68b has come out of guide rail 68a so that it may become parallel to a radial direction from rotation axis rah of handle section extending 61.
Therefore, when regulation slider 92 is pressed by compression spring 93b and regulation projection 92 is arranged in guide rail 68a, rotation to arm member 65 of handle section extending 61 comes to be regulated. On the other hand, if the 1st changeover switch 64 is operated, energizing force of compression spring 93b is resisted, and regulation slider 92 can pull up in guide rail 68a. In this case, handle member 60 can be rotated to arm member 65. If handle member 60 folds up and it is rotated to arm member 65 from a state to a position of condition of use, regulation projection 92a will fit in in regulation slot 68b, and body 20 of stroller 10 will come to be maintained by press of compression spring 93b at condition of use.
Next, a mechanism which regulates rotation to core member 25 of arm member 65 provided as 2nd state maintenance mechanism 95 is explained. As shown in Drawing 12 - Drawing 14, 2nd state maintenance mechanism 95 has piece 83 of state maintenance in which convex part 74 provided in forelimb linkage mechanism 70 and seat part 84 which can store convex part 74 were formed.
As shown in Drawing 12 - Drawing 14, convex part 74 is projected from a field on the backside of the 1st connector 73. Piece 83 of state maintenance was provided in core member 25, and has risen from core member 25. Piece 83 of state maintenance is arranged in a position which meets the 1st connector 73 of forelimb linkage mechanism 70, when a stroller is in condition of use on core member 25. As shown in Drawing 12 - Drawing 14, specifically, piece 83 of state maintenance is, It has curved back so that moving trucking rp (refer to Drawing 14) of convex part 74 at the time of folding up from condition of use and starting modification to a state may be met in general, and it may extend and it may estrange gradually from moving trucking rp of this convex part 74. And seat part 84 is formed in a position which meets convex part 74 when stroller 10 of the pieces 83 of state maintenance is in condition of use, as shown in Drawing 11.
That is, as shown in Drawing 14, in the state where convex part 74 of forelimb linkage mechanism 70 fits into seat part 84 of piece 83 of state maintenance, crookedness of arm member connecting linkage 72 is regulated. Thereby, modification (displacement) as the forelimb linkage mechanism 70 whole also comes to be regulated. however, this piece 83 of state maintenance can be set in a direction which has bent backward, i. e., the direction before and after estranging from forelimb linkage mechanism 70 (the 1st connector 73), -- backward, it is constituted so that it may bend. Therefore, a piece of state maintenance further comes to bend backward to the back side by pressing a piece of state maintenance to Drawing 14, at the back side (side which it is got blocked and estranged from the 1st connector 73 of forelimb linkage mechanism 70), as a two-dot chain line shows. Thereby, convex part 74 of forelimb linkage mechanism 70 slips out of seat part 84 of piece 83 of state maintenance, and modification of arm member connecting linkage 72 of it becomes possible.
As shown in Drawing 14, piece 83 of state maintenance comprises tabular material in which a part has bent backward. And seat part 84 is a field where piece 83 of state maintenance has not bent backward, and is formed in a portion prolonged in moving trucking rp of convex part 74 and parallel at the time of starting modification towards a fold-up state from condition of use. Therefore, convex part 74 stored in seat part 84 is effectively prevented from separating from seat part 84 by external force etc. which are not meant.
As shown in Drawing 10 - Drawing 14, in this embodiment, rocking member 75 which can be rocked to forelimb linkage mechanism 70 is provided. As shown in Drawing 14, rocking member 75 prolongs for them and comes out of grasping part 75a which an operator can grasp, and grasping part 75a, and has release lever part 75b which can be rocked synchronizing with grasping part 75a. Rocking member 75 is attached to the 1st connector 73 of forelimb linkage mechanism 70. As shown in Drawing 14, rocking axis sas to forelimb linkage mechanism 70 (the 1st connector 73) of rocking member 75 is prolonged in the surface of piece 83 of state maintenance and parallel which consist of tabular.
As shown in Drawing 14, rocking member 75 is arranged so that release lever part 75b may contact piece 83 of state maintenance, when it rocks in condition of use. And when an operator grasps grasping part 75a and makes rocking member 75 rock, release lever part 75b presses piece 83 of state maintenance from the front side to the back side. That is, by operating rocking member 75, it is forced piece 83 of state maintenance so that it may estrange from the 1st connector 73 of forelimb linkage mechanism 70. As a result, as a two-dot chain line shows to Drawing 14, it enables convex part 74 provided in forelimb linkage mechanism 70 to slip out of seat part 84 of piece 83 of state maintenance. Thus, engaging of clutch of forelimb linkage mechanism 70 and piece 83 of state maintenance is canceled, and modification of forelimb linkage mechanism 70 becomes possible. Therefore, rocking member 75 (release lever part 75b) comes to function as a changeover switch (the 2nd changeover switch) which operates 2nd state maintenance mechanism 95.
A mechanism which regulates crookedness of flection 62 of handle member 60 is established as 3rd state maintenance mechanism 97. Flection 62 of handle member 60 contains the 1st which received mutually and was connected so that rotation was possible - the 3rd flection 63a, 63b, and 63c while being attached to handle section extending 61 so that rotation is possible. And in flection 62, a mechanism which regulates rotation between rotation to handle section extending 61 of flection 62 and the 1st - the 3rd flection 63a, 63b, and 63c is incorporated.
As shown, for example in Drawing 4, in stroller 10, press button 98a for in other words changing into a state which can be rotated which is for canceling rotational regulation is provided in the 2nd flection 63b of flection 62. In addition, as shown in Drawing 4 and Drawing 17, operation regulation switch 98b which regulates displacement of press button 98a is further formed in the 2nd flection 63b of flection 62. That is, in order to operate 3rd state maintenance mechanism 97, where operation regulation switch 98b is canceled, it is necessary to press press button 98a. Thus, crookedness of flection 62 is regulated by 3rd state maintenance mechanism 97 in condition of use of stroller 10.
the [the above 1st -] -- body 20 of stroller 10 comes to be maintained by developed condition of use according to state maintenance mechanisms 91, 95, and 97 of three.
Here, operation of body 20 of stroller 10 at the time of folding up with condition of use and changing body 20 of stroller 10 between states is explained. First, operation at the time of folding up body 20 of stroller 10 in developed condition of use is explained.
for folding up from condition of use and changing body 20 of stroller 10 into a state -- the [the 1st -] -- state maintenance mechanisms 91, 95, and 97 of three are operated. For example, first, about 3rd state maintenance mechanism 97, where operation regulation switch 98b is canceled, press button 98a is pressed, and flection 62 of handle member 60 is changed into a state which can be crooked. And for example, it is made to change into the state where flection 62 was made crooked slightly, and this maintains flection 62 without the necessity of continuing pushing press button 98a, in the state where rotation has become possible.
Next, 2nd state maintenance mechanism 95 is operated. It is the aspect which grasped grasping part 75a of rocking member 75 as the 2nd changeover switch, and makes rocking member 75 specifically rock to forelimb linkage mechanism 70, as shown in Drawing 12 and Drawing 13. As shown in Drawing 14, release lever part 75b comes to press piece 83 of state support with rocking of rocking member 75. As a result, convex part 74 of forelimb linkage mechanism 70 slips out of seat part (penetration hole) 84 of piece 83 of state support, and forelimb linkage mechanism 70 will be in a state which can change.
3rd state maintenance mechanism 91 is operated. The 1st changeover switch 64 (for example, refer to Drawing 17) is slid to handle section extending 61, and, specifically, regulation slider 92 (refer to Drawing 15) arranged in handle section extending 61 is pulled up. With movement of this regulation slider 92, into slot 68 formed in handle support member 67 of arm member 65, regulation projection 92a of regulation slider 92 moves to guide rail 68a from regulation slot 68b (refer to Drawing 16). Thereby, rocking to arm member 65 (handle support member 67) of handle member 60 (handle section extending 61) is attained.
the [as mentioned above, / the 1st -] -- operating state maintenance mechanisms 91, 95, and 97 of threeAfter canceling a restraint which maintains body 20 of stroller 10 to condition of use, direction close to hind legs 40 (in side view shown in Drawing 3, it is direction of a clockwise rotation) is made to rock handle member 60 to an arm member. Rocking to arm member 65 of handle member 60 is transmitted to hind legs 40 by hind leg link material 88. As a result, with rocking of handle member 60, hind legs 40 are rocked to core member 25 so that an end of a side estranged from core member 25 may move ahead (it is direction of a clockwise rotation in side view shown in Drawing 3).
it mentioned above -- as -- estrangement of a pair of hind legs 40 -- an interval comes to approach mutually by rotating to core member 25. With approach of a pair of such hind legs 40, a pair of handle section extending 61 connected with a pair of hind legs 40 via hind leg link material 88 also comes to approach mutually. Specifically, handle support member 67 connected to one end of a pair of handle section extending 61 can approach mutually by rotation base 66 rocking and approaching mutually with approach operation of a pair of hind leg link material 88. Flection 62 connected to one end of a pair of handle section extending 61 can be crooked. estrangement [in / by these, a pair of handle section extending 61 also approaches mutually, and / the cross direction of a pair of handle section extending 61] -- an interval becomes narrow.
In condition of use, flection 62 of handle member 60 is projected from an end of another side of handle section extending 61 towards a side estranged from arm member 65 (core member 25), as a two-dot chain line shows to Drawing 17. On the other hand, as a solid line shows to Drawing 17, in a fold-up state, flection 62 of handle member 60 comes to be crooked so that it may project towards a side close to arm member 65 (core member 25) from an end of another side of handle section extending 61.
Approach operation of a pair of rotation bases 66 is transmitted to a pair of forelimbs 30 via forelimb linkage mechanism 70. First, with rotation operation of a pair of rotation bases 66, as shown in Drawings 11 and 13, arm member connecting linkage 72 of forelimb linkage mechanism 70 is crooked so that it may project up. Crookedness operation to the upper part of arm member connecting linkage 72 is transmitted to forelimb connecting linkage 78 via connection link 81, and it comes to be crooked so that forelimb connecting linkage 78 may also be projected up. With crookedness operation of such a forelimb connecting linkage 78, a pair of forelimbs 30 are rocked to core member 25 so that it can approach mutually in the cross direction. That is, hind legs 40 are rocked to core member 25 so that an end of a side estranged from core member 25 may move back (it is direction of a counterclockwise rotation in side view shown in Drawing 3).
It is carried out by rocking operation of handle member 60, rocking operation of forelimb 30, and rocking operation of hind legs 40 interlocking as mentioned above, and folds up from condition of use, and operation of body 20 of stroller 10 to a state is completed.
As shown in Drawing 5, in a fold-up state, a projection amount to back in the direction of order from handle member 60 and core member 25 of hind legs 40 becomes small sharply rather than condition of use. Similarly, a projection amount to the front in the direction of order from core member 25 of forelimb 30 also becomes small sharply rather than condition of use. In a fold-up state, a projection amount in the cross direction from core member 25 of handle member 60, hind legs 40, and forelimb 30 also becomes small sharply rather than condition of use. Since handle member 60 has prolonged and come out towards a lower part in a fold-up state, height in the up-and-down direction of stroller 10 has also been sharply made low. Thus, a size of body 20 of stroller 10 can be sharply miniaturized by folding up from condition of use in the direction of order, the cross direction, and the up-and-down direction.
As mentioned above, in condition of use, from a pair of handle section extending 61, sturdy part 62 of handle member 60 is projected above back, and crooks and enters in a pair of handle section extending 61 in a fold-up state. For this reason, a thing for which a projection amount of handle member 60 in condition of use is set as suitable length in consideration of the maneuverability drivability of stroller 10, It is [shortening the length of handle member 60 in a fold-up state enough, and making a size in a size of stroller 10, division, and the up-and-down direction miniaturize sharply] compatible.
The 1st which makes a rocking axis of flection 62 to handle section extending 61, and flection 62 as shown in Drawing 5 - rocking axis ba between the 3rd flection 63a, 63b, and 63c, It has extended in the direction which abbreviated-intersects perpendicularly to virtual plane vp demarcated by a pair of handle section extending 61 arranged in parallel. For this reason, projection amount pl of flection 62 from virtual plane vp demarcated by a pair of handle section extending 61 cannot become large, and, thereby, it can make a size in a fold-up state fully miniaturize, when flection 62 is crooked as shown in Drawing 5.
As mentioned above, rotation axis raf (for example, refer to Drawing 8 and Drawing 9) to core member 25 of forelimb 30 inclines so that it may be located in a lower part in the up-and-down direction, while the cross direction outside is located in back in the direction of order rather than a cross direction inner side. The 1st hind leg element and the 2nd hind leg element 42 of hind legs 40 constitute a parallelogram-like link with career support member 43 and core member 25. Also in the state where this folded up as shown in Drawing 5 - Drawing 7, back wheel 47 supported by front wheel 35 and hind legs 40 which were supported by forelimb 30 is maintained at the same posture as condition of use, and an axis-of-rotation line of front wheel 35 and an axis-of-rotation line of back wheel 47 are parallel to condition of use. Therefore, body 20 of stroller 10 in a fold-up state can stand up to sidewall via front wheel 35 and back wheel 47. As a result, body 20 of stroller 10 in a fold-up state can be made very easy to deal with. Grasping part 75a of rocking member 75 can be grasped, body 20 of stroller 10 can also be operated, and, thereby, the operativity of body 20 of stroller 10 in a fold-up state can be raised markedly.
By the way, in this embodiment, a modification energizing member which energizes change (modification and displacement) of body 2 which was folded up from condition of use and turned to a state is included in body 20 of stroller 10. As shown in Drawing 9, specifically, a tensile spring as 1st modification energizing member 16 is provided between each hind leg 40 and core member 25. With a spring as 1st modification energizing member 16, each hind leg 40 is energized so that an end of a side estranged from the core member 25 may move ahead in the direction of order, namely, so that it may rotate to core member 25 in side view of Drawing 3 to direction of a clockwise rotation.
As shown in Drawing 9, a tensile spring as 2nd modification energizing member 17 is provided between each forelimb 30 and that of core member 25. With a spring as 2nd modification energizing member 17, each forelimb 30 is energized so that an end of a side estranged from the core member 25 may move to back in the direction of order, namely, so that it may rotate to core member 25 in side view of Drawing 3 to direction of a counterclockwise rotation.
The surroundings of a bending-axis line of arm member connecting linkage 72 of forelimb linkage mechanism 70 are provided with a torsion spring as 3rd modification energizing member 18 (refer to Drawing 11). With a spring as 3rd modification energizing member 18, arm member connecting linkage 72 is energized towards the state of carrying out sturdy so that it may project upwards, from a state prolonged horizontally.
the [such the 1st -] -- canceling the 1st - the 3rd status maintenance mechanism 91, 95, and 97 according to modification energizing members 16, 17, and 18 of three, Automatically, body 20 of stroller 10 in condition of use comes to change into a fold-up state, and stabilizes for it and folds up body 20 of stroller 10, and it can continue maintaining in the state. First of all, folding operation of this stroller 10 is easy in order that the direction of an axis of handle member 60 may not move greatly in the up-and-down direction or the direction of order during the rocking concerned, while making handle member 60 only rock to one way. And according to such modification energizing members 16, 17, and 18 and status maintenance mechanisms 91, 95, and 97, folding operation of stroller 10 can be made still easier.
Next, operation of body 20 of stroller 10 at the time of developing body 20 of stroller 10 in a fold-up state is explained.
Folding operation of body 20 of stroller 10 at the time of developing body 20 of stroller 10 in a fold-up state becomes operation and a contrary which were mentioned above. Direction estranged from hind legs 40 (in side view shown in Drawing 3, it is direction of a counterclockwise rotation) is made to specifically rock handle member 60 to arm member 65. With rocking operation of this handle member 60, forelimb 30, hind legs 40, and arm member 65 rock to core member 25, and body 20 is developed.
Flection 62 will be developed while a pair of handle section extending 61 of handle member 60 estranges from each other at this time. When flection 62 will be in once developed condition of use, it has it regulated to be crooked according to 3rd state maintenance mechanism 97. And a pair of handle section extending 61 comes to be held by flection 62 which had crookedness operation regulated at maintenance estranged from each other.
If body 20 of stroller 10 is developed by condition of use, convex part 74 of forelimb linkage mechanism 70 will be guided at piece 83 of state support prolonged along with the moving trucking rp, and will come to enter in seat part (penetration hole) 84 formed in piece 83 of state support. Thus, modification of forelimb linkage mechanism 70 comes to be regulated by engaging of clutch of convex part 74 of forelimb linkage mechanism 70 and seat part (penetration hole) 84 of piece 83 of state support which make 2nd state maintenance mechanism 95.
As shown in Drawing 15, regulation slider 92 which makes 1st state maintenance mechanism 91 is energized with compression spring 93b in handle section extending 61. And if body 20 of stroller 10 is developed by condition of use, regulation projection 92a of regulation slider 92 will come to enter to regulation slot 68b from guide rail 68a of slot 68 formed in handle support member 67 of arm member 65. If regulation projection 92a enters to regulation slot 68b, rotation (rocking) to handle support member 67 of handle section extending 61 will come to be regulated. Thus, rocking to arm member 65 of handle member 60 comes to be regulated by engaging of clutch of regulation slider 92 which makes 1st state maintenance mechanism 91, and slot 68.
Energizing force of the 1st - the 3rd energizing member 16, 17, and 18 which were mentioned above as mentioned above is resisted, and handle member 60, forelimb 30, and hind legs 40 are made to rock, it can be made to change into condition of use which had body 20 of stroller 10 developed -- the [and / the 1st -] -- it is automatically fixable to condition of use according to state maintenance mechanisms 91, 95, and 97 of three. Therefore, deployment operation of stroller 10 as well as folding operation of stroller 10 can be performed very easily.
Next, lessons is taken from rear wheel career 50 held via career support member 43 in a lower end of each hind leg 40, and rear wheel unit 45 held at rear wheel career 50, and it further explains in full detail.
For example, as shown in Drawing 1 - Drawing 7, rear wheel career 50 is supported by end of a side estranged from core member 25 of each hind leg 40 via career support member 43, respectively. On the other hand, each rear wheel unit 45 has brake ring 48 which can rotate to axle 46 synchronizing with axle 46 removably supported by corresponding rear wheel career 50, back wheel 47 rotatably supported by axle 46, and back wheel 47. And rear wheel unit 45 comes to be removably held to rear wheel career 50.
ブレーキン ring 48 is having many slots 48c for regulation formed in a field of a side which comes to meet rear wheel career 50 after having been supported by rear wheel career 50. Slot 48c for regulation is put in order and arranged at a peripheral direction of a virtual circle centering on axle 46. Each slot 48c extends in a radial direction centering on axle 46, and it is carrying out the opening to a radial inner side. This ブレーキン ring 48 comes to have rotation centering on axle 46 regulated when engaging member 55 for regulation projected from rear wheel career 50 so that movement is possible enters in slot 48c for regulation. Regulation of rotation of ブレーキン ring 48 will also come to regulate rotation to axle 46 of back wheel 47. Engaging member 55 for regulation is behind explained in full detail with a component of others of rear wheel career 50.
As shown in Drawing 19, to career support member 43, rear wheel career 50 is a predetermined angle range, and it is connected to career support member 43 so that rotation may become possible focusing on rotation axis rag prolonged horizontally. Suspension 44 is provided between rear wheel career 50 and career support member 43. By rotation of rear wheel career 50 to career support member 43 in the state where it was energized by suspension 44, a shake, distortion, etc. of body 20 resulting from unevenness of the ground (running surface) under run of stroller 10 can be controlled.
As shown in Drawing 20, Drawing 22, and Drawing 22, stroller 10 by this embodiment has a pair of 1st rear wheel units 45a and a pair of 2nd rear wheel units 45b which are used alternatively. Any a pair of rear wheel units of a pair of 1st rear wheel units 45a and a pair of 2nd rear wheel units 45b are chosen, and a pair of rear wheel units concerned come to be held at each of a pair of rear wheel careers 50. As shown in Drawing 20, a path of 1st back wheel 47a of the 1st rear wheel unit 45a is larger than a path of 2nd back wheel 47b of 2nd rear wheel unit 45b. Back wheel 47a of the 1st rear wheel unit 45a has the hollow tire made of rubber into which air was injected, and back wheel 47a of the 2nd rear wheel unit 45a has a solid tire made of rubber in which air is not poured in. A path of ブレーキン ring 46a of the 2nd rear wheel unit 45a is larger than a path of back wheel 47b of 2nd rear wheel unit 45b.
Thus, when it has two kinds of wheel units 45a and 45b which can renew one stroller 10, wheel unit 45 which contains suitable back wheel 47 according to a situation of a road surface (sidewall, running surface) stroller 10 comes to run can be chosen. When stroller 10 comes to run a big concavo-convex road surface top as an example, 1st rear wheel unit 45a is chosen suitably. When 1st rear wheel unit 45a is used, a shake and distortion of stroller 10 resulting from unevenness of a road surface can be absorbed by back wheel 47a constituted so that a hollow tire made of rubber of a diameter of a large might be included. Thereby, the stability of stroller 10 is raised, and it can be stabilized more safely and more and can be made to run stroller 10 by which infants have ridden. When coming to run a place where stroller 10 was crowded as other examples, 2nd rear wheel unit 45b is chosen suitably. When 2nd rear wheel unit 45a is used, by back wheel 47b constituted so that a solid tire made of rubber of a byway might be included, a small turn can become possible and it can raise maneuverability drivability.
Rear wheel career 50 according [in / as shown in Drawing 22 and Drawing 23 / condition of use] to this embodiment, Axle 46a of the 1st rear wheel unit 45a and axle 46b of the 2nd rear wheel unit 45b are supported to different perpendicular direction position (up-and-down direction position) vp1 and vp2 (refer to Drawing 19). As shown in Drawing 22 and Drawing 23, axle 46a of the 1st rear wheel unit 45a which supports back wheel 47a containing a tire of a diameter of a large comes to be supported by upper position vp1 in the perpendicular direction rather than axle 46b of the 2nd rear wheel unit 45b which supports back wheel 47b containing a tire of a byway. Even if this replaces the 1st rear wheel unit 45a and the 2nd rear wheel unit 45b respectively with back wheels 47a and 47b from which a path differs, neither height of body 20 of stroller 10 nor height of a position where infants ride changes. Therefore, it can prevent causing change of a centroid position of stroller 10, change of a field of view of infants who took stroller 10, etc. by exchanging rear wheel units 45a and 45b. Thereby, a fall of maneuverability drivability resulting from change of a centroid position, a fall of roadability, a fall of a degree of comfort, etc. can be prevented.
It is [in / especially / this embodiment] axle 46a of the 1st rear wheel unit 45a, a radius of back wheel 47a of the 1st rear wheel unit 45a, a radius of back wheel 47b of the 2nd rear wheel unit 45b, a difference of 、, and abbreviation -- in a position above the perpendicular direction, only an equal part is held at rear wheel career 50 rather than axle 46b of the 2nd rear wheel unit 45b. Therefore, even if rear wheel career 50 holding rear wheel units 45a and 45b holds which rear wheel units 45a and 45b, it comes to be arranged from sidewall in the fixed perpendicular direction position. Therefore, neither change of a centroid position of stroller 10 nor change of a field of view of infants who took stroller 10 is caused by exchanging rear wheel units 45a and 45b.
In this embodiment, it is a radius of back wheel 47a of the 1st rear wheel unit 45a, a radius of back wheel 47b of the 2nd rear wheel unit 45b, a difference of 、, and abbreviation -- only as for an equal part, a radius of brake ring 48a of the 1st rear wheel unit 45a has become larger than a radius of brake ring 48b of the 2nd rear wheel unit 45b. In this case, as shown in Drawing 22 and Drawing 23, it becomes possible to carry out engaging of clutch of single engaging member 55 for regulation, and the brake rings 48a and 48b of both rear wheel units 45a and 45b. That is, composition of rear wheel career 50 can be simplified and a weight saving, a miniaturization, etc. can be attained.
Here, composition for holding rear wheel units 45, 45a, and 45b on rear wheel career 50 is explained.
As shown in Drawing 21, each of a pair of rear wheel careers 50 has main part 51 as a casing, attachment component (in an example to illustrate, it is a maintenance plate) 56 arranged in main part 51, and energization spring 57 which pulls up maintenance plate 56 to the upper part below the perpendicular direction. Some maintenance plates 56 are outside exposed from main part 51, and it constitutes manual operation button 56a (for example, refer to Drawing 18). By pressing manual operation button 56a from the outside of main part 51, energizing force of energization spring 57 can be resisted and maintenance plate 56 can be depressed in the perpendicular direction lower part within main part 51.
As shown in Drawing 19 and Drawing 21, the 1st hole 51a1 that receives axle 46a of the 1st rear wheel unit 45a, and the 2nd hole 51a1 that receives axle 46b of the 2nd rear wheel unit 45b are estranged and formed in the perpendicular direction at main part 51. In the state where maintenance plate 56a was able to be pulled up with energization spring 57, In the 1st contact portion 56b1 that is arranged in a position which meets the 1st hole 51a1, and closes the 1st hole 51a1 partially from a lower part, and the state where it was able to pull up with energization spring 57, It has the 2nd contact portion 56b2 that is arranged in a position which meets the 2nd hole 51a2, and closes the 2nd hole 51a1 partially from a lower part. On the other hand, as shown in Drawing 20, Drawing 22, and Drawing 23, a tip of axles 46, 46a, and 46b of each rear wheel unit 45, 45a, and 45b is formed so that it may taper off. As shown in Drawing 20, Drawing 22, and Drawing 23, near the tip of axles 46a and 46b, circumference-like slot 46a1 and 46b1 are formed.
In such composition, a tip of axles 46, 46a, and 46b of rear wheel units 45, 45a, and 45b is only inserted in the 1st hole 51a1 or 2nd hole 51a2 of rear wheel career 50, and rear wheel units 45, 45a, and 45b come to be held at rear wheel career 50. Specifically, contact portion 56b1 of maintenance plate 56 and 56b2 are pressed downward [perpendicular direction] by tip of axles 46, 46a, and 46b formed in tapered shape. Thereby, axles 46, 46a, and 46b go to an inside of main part 51 over maintenance plate 56. At this time, contact portion 56b1 of maintenance plate 56 and 56b2 contact axles 46, 46a, and 46b from a lower part according to energizing force from energization spring 57. Finally, as shown in Drawing 22 and Drawing 23, contact portion 56b1 of maintenance plate 56 and 56b2 enter into circumferential groove 46a1 of axles 46, 46a, and 46b, and 46b1, and movement which met in the direction of an axis of axles 46, 46a, and 46b comes to be regulated. Rear wheel units 45, 45a, and 45b which did in this way and were held at rear wheel career 50 can be removed from rear wheel career 50 by pressing manual operation button 56a and depressing maintenance plate 56 within main part 51.
Next, composition and an operation which regulate rotation of rear wheel 47 of rear wheel unit 45 are explained. Be understood from Drawing 24 and Drawing 25 omitting back wheel 47 and in which showing a lower end part of a pair of hind legs 40, Rear wheel unit 45 which each of a pair of rear wheel careers 50 has engaging member 55 for regulation, and was supported by each rear wheel career 50 has ブレーキン ring 48 which engages with engaging member 55 for regulation. Therefore, a pair of rear wheels 48 come to have rotation regulated separately, respectively.
However, as shown in Drawing 24 and Drawing 25, transmission mechanism 100 is established between one rear wheel career (1st rear wheel career) 50a and rear wheel career (2nd rear wheel career) 50b of another side. And according to transmission mechanism 100, movement of engaging member 55 for regulation of one rear wheel career 50a is transmitted to rear wheel career 50b of another side, and engaging member 55 for regulation of rear wheel career 50b is interlocked with engaging member 55 for regulation of one rear wheel career 50a, and moves. For this reason, in this embodiment, rotation of rear wheel 47 of rear wheel unit 45 held on both rear wheel careers 50a and 50b can be regulated, without only operating one rear wheel career 50a, and operating rear wheel career 50b of another side.
First, composition and an operation of one side of rear wheel career 50a are explained. As shown in Drawing 26, it is rear wheel career 50a, Main part (casing) 51 holding axle 46 of wheel unit 45 mentioned above, It has sliding member 111 slidable to one way, and energizing member 117 in which it is arranged in main part 51 and the above 1 side energizes a sliding member from 1 side to main part 51 towards other sides of the side opposite to along one way to main part 51.
In this embodiment, one way is the up-and-down direction (the perpendicular direction) in general. A 1 side in one way is the bottom in the up-and-down direction, and a side is the upper part in the up-and-down direction also in one way.
Engaging member 55 for regulation which may enter slot 48c for regulation of ブレーキン ring 48 of wheel unit 45 is attached to sliding member 111. When external force is not applied, sliding member 111 is constituted so that it may be held whether they are 1st holding position rp1, 2nd holding position rp2 which are located in a 1 side along the one way rather than 1st holding position rp1, and のいずれ. When sliding member 111 is held 2nd holding position rp2 (state shown in Drawing 22 and Drawing 23 according to a two-dot chain line), engaging member 55 for regulation enters slot 48c for regulation of ブレーキン ring 48 of wheel unit 45, and comes to regulate rotation to axle 46 of back wheel 47. When sliding member 111 is held on the other hand 1st holding position rp1 (state shown in Drawing 22 and Drawing 23 as a solid line), Engaging of clutch of engaging member 55 for regulation and wheel unit 45 is canceled, namely, engaging member 55 for regulation slips out from slot 48c for regulation of ブレーキン ring 48 of wheel unit 45, and rotation of it to axle 46 of back wheel 47 is attained.
As shown in Drawing 26, two long holes 112a and 112b are formed in sliding member 111. Each long hole 112a and 112b is formed in hole 51a1 in which axles 46, 46a, and 46b mentioned above are inserted, and a position which meets 51a2.
Sliding member 111 has final controlling element 113 which can apply now external force for turning sliding member 111 to other sides (under the up-and-down direction), and pressing it from another side (on the up-and-down direction). This final controlling element 113 consists of a part of sliding member 111, and is constituted in one with sliding member 111. For this reason, final controlling element 113 comes to move to one way in conjunction with an engaging member for regulation. Final controlling element 50 is provided in the exterior of main part 51, and is arranged near the back wheel 47 in a lower end field of hind legs 47. Directly, a user can contact final controlling element 113 and can apply external force now.
and -- sliding member 111 is once pressed towards a 1 side along one way from another side -- further -- stricta position [like] which is kept whenever it is pressed across the 2nd holding position towards a 1 side from another side and is returned to other sides from 1 side by energizing force of energizing member 117 after that and come to be alike of a position is constituted so that it may change by turns between 1st holding position rp1 and 2nd holding position rp2. Sliding member 111 is [in / especially / this embodiment], a position [like] which is returned to other sides by energizing force of energizing member 117 from 1 side whenever [along one way] within the limits [slidable] is most slid to a position by the side of one, and is kept and come to be alike of a position is constituted so that it may change by turns between 1st holding position rp1 and 2nd holding position rp2. Specifically, it is constituted so that it may explain below.
Either one of main part 51 and sliding member 111 is fields almost parallel to one way, and it includes field 115 in which engagement groove 116 which extends in a line was formed. On the other hand, the tip is inserting member 119 arranged in engagement groove 116, and inserting member 119 which is having displacement to the one way regulated is supported by another side of main part 51 and sliding member 111. In an example shown in Drawing 26, other side edge parts of inserting member 119 were fixed to main part 51, and inserting member 119 has hung towards a 1 side in one way from main part 51. Inserting member 119 is constituted by metal line (metal stick). On the other hand, as shown in Drawing 26, sliding member 111 includes field 115 in which engagement groove 116 which extends in a line was formed.
Inserting member 119 is prolonged from the other side to a 1 side along one way. However, as shown in Drawing 27, 90 degrees of tip parts of the one end side of inserting member 119 were bent, are the 法線 method of field 115 of sliding member 111, and have extended along a depth direction of engagement groove 116. A tip of inserting member 119 extends in engagement groove 116. A tip of inserting member 119 and bottom 116a of engagement groove 116 were turned mutually, it was pressed, and a tip of inserting member 119 is in contact with bottom 116a of engagement groove 116. Inserting member 119 is having movement to one way regulated. However, when thin length-like inserting member 119 bends, it can move in the direction which intersects perpendicularly with one way in a tip of inserting member 119. In such composition, free movement of sliding member 111 to main part 51 which supports inserting member 119 by engaging of clutch of inserting member 119 and engagement groove 116 which had engagement groove 116 formed is regulated.
Up to the 2nd cuff position p2 where engagement groove 116 is located in other sides rather than the 1st cuff position p1 in one way from the 1st cuff position p1 as shown in Drawing 27, Up to the 1st slot course c1 of を結ぶ, and the 3rd cuff position p3 located in a 1 side rather than the 2nd cuff position p2 in one way from the 2nd cuff position p2, Up to the 2nd slot course c2 of を結ぶ, and the 4th cuff position p4 located in other sides rather than the 3rd cuff position p3 in one way from the 3rd cuff position p3, It has the 3rd slot course c3 of を結ぶ, the 4th slot course c4 which connects from the 4th cuff position p4 to the 1st cuff position p1 located in a 1 side rather than the 4th cuff position p4 in one way, and a course constituted as be alike. and engagement groove 116 and inserting member 119 -- inserting member 119 -- the [the 1st -] -- it is constituted so that it may arrive at cuff positions p1-p4 of four in this turn and engagement groove 116 may be gone around.
As shown in Drawing 27, it intersects perpendicularly with one way on field 115 in which engagement groove 116 was formed, and also in a direction, the 1st cuff position p1 and the 3rd cuff position p3 are arranged between the 2nd cuff position p2 and the 4th cuff position p4. Thereby, engagement groove 116 is formed in the shape of a circumference, without [without it forms a turning up point in one way in addition to 1st - 4th cuff position p1 - p4, and] producing intersection of a course.
In this embodiment, the depth of engagement groove 116 of the 2nd slot course c2 is deeper than the depth of engagement groove 116 of the 1st slot course c1 in a field in which the 1st slot course c1 and the 2nd slot course c2 join in engagement groove 116 (connection). As a result, as shown in Drawing 27 and Drawing 28, level difference s2 in alignment with the 2nd slot course c2 is formed. And inserting member 119 which arrived at the 2nd cuff position p2 with this level difference s2, Then, when carrying out relative displacement towards the one-way 1 side to engagement groove 116, with level difference s2, entering to the 1st slot course c2 is checked, and it comes to be guided to the 3rd cuff position p3 in accordance with the 2nd slot course c2.
In a field in which the 2nd slot course c2 and the 3rd slot course c3 join in engagement groove 116 (connection), the depth of engagement groove 116 of the 3rd slot course c3 is deeper than the depth of engagement groove 116 of the 2nd slot course c2. As a result, as shown in Drawing 27 and Drawing 28, level difference s3 in alignment with the 3rd slot course c3 is formed. With this level difference s3, inserting member 119 which arrived at the 3rd cuff position p3 comes to be guided to the 4th cuff position p4 in accordance with the 3rd slot course c3 after that.
In a field in which the 3rd slot course c3 and the 4th slot course c4 join in engagement groove 116 (connection), the depth of engagement groove 116 of the 4th slot course c4 is deeper than the depth of engagement groove 116 of the 3rd slot course c3. As a result, as shown in Drawing 27, level difference s4 in alignment with the 4th slot course c4 is formed. With this level difference s4, inserting member 119 which arrived at the 4th cuff position p4 comes to be guided to the 1st cuff position p1 in accordance with the 4th slot course c4 after that.
In addition, in a field in which the 4th slot course c4 and the 1st slot course c1 join in engagement groove 116 (connection), the depth of engagement groove 116 of the 1st slot course c1 is deeper than the depth of engagement groove 116 of the 4th slot course c4. As a result, as shown in Drawing 27, level difference s1 in alignment with the 1st slot course c1 is formed. As a two-dot chain line shows to Drawing 27, inserting member 119 which arrived at the 1st cuff position p1 comes to be guided to the 2nd cuff position p2 in accordance with the 1st slot course c1 after that with this level difference s1.
Thus, a thing for which relative displacement towards the engagement groove 116 and one-way 1 side of inserting member 119 and relative displacement towards a side besides one way of engagement groove 116 and inserting member 119 are repeated, inserting member 119 -- the [the 1st -] -- it arrives at cuff positions p1-p4 of four in this turn, and comes to go engagement groove 116 around.
As mentioned above, in this embodiment, engagement groove 116 is formed in one field 115 of sliding member 111, and inserting member 119 is supported by main part 51 in a side edge part besides the one way. Sliding member 111 is energized by energizing member 117 towards other sides from the 1 side of one way. As a result, engagement groove 116 is energized by energizing member 117 so that relative displacement may be carried out from the one-way 1 side (under the perpendicular direction) towards other sides (on the perpendicular direction) to an inserting member. In Drawing 27, slot 116 tends to carry out relative displacement to inserting member 119 towards the upper-and-lower-sides side below space.
For this reason, when the failure of the external force is not carried out to sliding member 111, inserting member 119 comes to be arranged in the 1st cuff position p1 or the 3rd cuff position p3 which forms a cuff projected towards the one-way 1 side. And in this embodiment, when inserting member 119 is located in the 1st cuff position p1 of engagement groove 116, sliding member 111 will be arranged 1st holding position rp1 (position shown in Drawing 19) located above the perpendicular direction. On the other hand, when inserting member 119 is located in the 3rd cuff position p3 of engagement groove 116, sliding member 111 will be arranged 2nd holding position rp2 (position shown in Drawing 24) located above the perpendicular direction.
As a solid line shows to Drawing 22 and Drawing 23, when sliding member 111 is located in the 1st holding position, Engaging member 55 for regulation attached to sliding member 111 has escaped from and come out from slot 48c for regulation of ブレーキン ring 48 of rear wheel unit 45, and rotation of back wheel 47 which synchronizes with ブレーキン ring 48 is not regulated. As a two-dot chain line shows to Drawing 22 and Drawing 23 on the other hand, when sliding member 111 is located in the 2nd holding position, Engaging member 55 for regulation attached to sliding member 111 enters slot 48c for regulation of ブレーキン ring 48 of rear wheel unit 45, and rotation of back wheel 47 which synchronizes with ブレーキン ring 48 comes to be regulated.
And when inserting member 119 is located in the 1st cuff position p1 of engagement groove 116, and sliding member 111 is turned to a 1 side and pressed from a side besides one way, If sliding member 111 in which engagement groove 116 was formed moves to the one-way 1 side and it says conversely to main part 51 holding inserting member 119, it will carry out relative displacement of the inserting member 119 to a side besides one way to engagement groove 116. At this time, inserting member 119 does not enter into the 4th slot course c4 with level difference s4, but follows the 1st slot course c1. As a result, by thrust from the outside, sliding member 111 is movable to the one-way 1 side until inserting member 119 arrives at the 2nd cuff position p2 of engagement groove 116.
In a place where inserting member 119 arrived at the 2nd cuff position p2 of engagement groove 116, If press to sliding member 111 from the outside is canceled, sliding member 111 in which engagement groove 116 was formed will move to a side besides one way to main part 51 holding inserting member 119 according to energizing force of energizing member 117. As mentioned above, at this time, inserting member 111 does not enter into the 1st slot course c1 with level difference s1, but follows the 2nd slot course c2. As a result, according to energizing force from energizing member 117, sliding member 111 comes to move to a side besides one way until inserting member 119 arrives at the 3rd cuff position p3 of engagement groove 116.
Inserting member 119 will be caught in engagement groove 116 by a certain inconvenience, for example, When inserting member 119 is not able to be pressed and moved from the 1st cuff position p1 to the 2nd cuff position p2, by energizing force from energizing member 117, inserting member 117 returns to the 1st cuff position p1 again, and sliding member 111 is held again in the 1st holding position. In this case, the operator can grasp further that operation was not performed as planned by the position of final controlling element 113 which began to be prolonged from main part 51 by not having been obtained while inserting member 119 operated a feel which falls the 2nd level difference s2.
If similarly sliding member 111 is turned to a 1 side and pressed from a side besides one way, when inserting member 119 is located in the 3rd cuff position p3 of engagement groove 116, If sliding member 111 in which engagement groove 116 was formed moves to the one-way 1 side and it says conversely to main part 51 holding inserting member 119, it will carry out relative displacement of the inserting member 119 to a side besides one way to engagement groove 116. At this time, inserting member 111 does not enter into the 2nd slot course c2 with level difference s2, but follows the 3rd slot course c3. As a result, by thrust from the outside, sliding member 111 is movable to the one-way 1 side until inserting member 119 arrives at the 4th cuff position p4 of engagement groove 116.
In a place at which inserting member 119 arrived to the 4th cuff position p4 of engagement groove 116, If press to sliding member 111 from the outside is canceled, sliding member 111 in which engagement groove 116 was formed will move to a side besides one way to main part 51 holding inserting member 119 according to energizing force of energizing member 117. As mentioned above, at this time, inserting member 111 does not enter into the 3rd slot course c1 with level difference s3, but follows the 4th slot course c4. As a result, according to energizing force from energizing member 119, sliding member 111 comes to move to a side besides one way until inserting member 119 arrives at the 1st cuff position p1 of engagement groove 116.
When inserting member 119 is not able to be pressed and moved by a certain inconvenience from the 3rd cuff position p3 to the 2nd cuff position p4, it is the energizing force from energizing member 117, Inserting member 117 returns to the 3rd cuff position p3 again, and sliding member 111 is held again in the 2nd holding position. In this case, the operator can grasp further that operation was not performed as planned by the position of final controlling element 113 which began to be prolonged from main part 51 by not having been obtained while inserting member 119 operated a feel which falls the 4th level difference s3.
Whenever sliding member 111 is pressed towards a 1 side along one way from another side as mentioned above, are still stricter, a position [like] which is returned to other sides by energizing force of energizing member 117 from 1 side whenever it is pressed across the 2nd holding position towards a 1 side from another side, and is kept and come to be alike of a position comes to change by turns between 1st holding position rp1 and 2nd holding position rp2. Therefore, it is realizable only by adding external force to one direction which met a change of the state of regulating rotation of a rear wheel, the state of enabling rotation of a back wheel, and 、 in the one direction to sliding member 111.
In this embodiment, external force can especially be applied to sliding member 111 via final controlling element 113 arranged near the back wheel 47 as well shown in Drawing 18. According to such composition, the operator can switch to a state which can rotate back wheel 47, and a state which cannot rotate back wheel 47 only by stepping on final controlling element 113 on foot. Therefore, it can switch to switching to a state where back wheel 47 cannot be rotated, and a state where back wheel 47 cannot be rotated, preventing moving in the direction which hangs a hand on handle member 60 and body 10 of stroller 10 does not mean. Such operation can be performed in an impossible posture which is not, and it can also be performed, without letting out of sight further infants who rode on stroller 10.
After explaining above, composition which regulates and deregulates rotation of wheel 47 is only mere illustration, and it may change it variously. For example, composition about above-mentioned engagement groove 116 and inserting member 119 may be transformed as shown in Drawing 30 - Drawing 32. Addition of external force to one direction which met in the one direction can perform a change in the state of enabling rotation of the state of regulating rotation of back wheel 47, and back wheel 47, also by these modification [like]. Explanation about the following modification is given only about a different point from an embodiment mentioned above. Drawing 30 - Drawing 32 are figures for explaining a modification of one rear wheel career (1st rear wheel career) 50a, and are a figure typically shown where a main part and a sliding member of a rear wheel career are decomposed. In Drawing 30 - Drawing 32, the same numerals are given to a portion which may be constituted identically to an embodiment mentioned above.
In an example shown in Drawing 30, courses (outline) of engagement groove 116 only differ, and others are constituted identically to an embodiment mentioned above. When inserting member 119 has been arranged in an example shown in Drawing 30 in the 1st cuff position p1 of engagement groove 116, When sliding member 111 (engaging member 55 for regulation) is held in the 1st holding position and inserting member 119 has been arranged in the 3rd cuff position p3 of engagement groove 116, sliding member 111 (engaging member 55 for regulation) comes to be held in the 2nd holding position. The 2nd cuff position p2 and the 4th cuff position p4 are arranged in a mutually different position in one way, and the 1st cuff position p1 and the 3rd cuff position p3 are arranged in a mutually different position in one way. The 2nd cuff position p2 and the 4th cuff position p4 are arranged in for [the] another side between the 1st cuff position p1 and the 3rd cuff position p3.
In an example shown in Drawing 31, engagement groove 116 is formed on one field 115 of main part 51. Inserting member 119 is held in an end of a side besides the above at sliding member 111. When inserting member 119 has been arranged in an example shown in Drawing 31 in the 2nd cuff position p2 of engagement groove 116, When sliding member 111 (engaging member 55 for regulation) is held in the 1st holding position and inserting member 119 has been arranged in the 4th cuff position p4 of engagement groove 116, sliding member 111 (engaging member 55 for regulation) comes to be held in the 2nd holding position. The 2nd cuff position p2 and the 4th cuff position p4 are arranged in a mutually different position in one way, and the 1st cuff position p1 and the 3rd cuff position p3 are arranged in a mutually different position in one way. The 1st cuff position p1 and the 3rd cuff position p3 are arranged in for [the] another side between the 2nd cuff position p2 and the 4th cuff position p4.
In an example shown in Drawing 32, engagement groove 116 is formed on one field 115 of main part 51. Inserting member 119 is held in an end of a side besides the above at sliding member 111. When inserting member 119 has been arranged in an example shown in Drawing 32 in the 4th cuff position p4 of engagement groove 116, When sliding member 111 (engaging member 55 for regulation) is held in the 1st holding position and inserting member 119 has been arranged in the 2nd cuff position p2 of engagement groove 116, sliding member 111 (engaging member 55 for regulation) comes to be held in the 2nd holding position. The 2nd cuff position p2 and the 4th cuff position p4 are arranged in a mutually different position in one way. The 2nd cuff position p2 and the 4th cuff position p4 are arranged in for [the] another side between the 1st cuff position p1 and the 3rd cuff position p3.
By the way, as mentioned above, between rear wheel career 50a, rear wheel career 50b of another side, and 、, it is [the above composition], Transmission mechanism 100 for transmitting move operation of a sliding member of one rear wheel career (1st rear wheel career) 50a to rear wheel career (2nd rear wheel career) 50b of another side is established. By stroller 10 according to this embodiment by such composition, Above-mentioned very simple and simple operation is only performed to final controlling element 113 of one rear wheel career 50a, Rotation regulation operation and rotation deregulation operation can be performed also to back wheel 47 supported by rear wheel career 50b of not only back wheel 47 supported by one rear wheel career 50a but another side. Hereinafter, rear wheel career 50b and transmission mechanism 100 of another side are explained.
As shown in Drawing 29, it is rear wheel career 50b, Main part (casing) 51 holding axle 47 of wheel unit 45 mentioned above, It has sliding member 121 slidable to one way, and energizing member 127 in which it is arranged in main part 51 and the above 1 side energizes sliding member 121 from 1 side to main part 51 towards other sides of the side opposite to along one way to main part 51. Engagement groove 55 for regulation is attached to energizing member 121.
Into [member / sliding] main part 51 in 121, between the 1st holding position, the 2nd holding position (position shown in Drawing 27 as a solid line) in which it is located along one way at other sides rather than the 1st holding position, and 、 is movable. When sliding member 121 is held in the 2nd holding position (state shown in Drawing 25), engaging member 55 for regulation enters slot 48c for regulation of ブレーキン ring 48 of wheel unit 45, and comes to regulate rotation to axle 46 of back wheel 47. When sliding member 121 is held on the other hand in the 1st holding position, Engaging of clutch of engaging member 55 for regulation and wheel unit 45 is canceled, namely, engaging member 55 for regulation slips out from slot 48c for regulation of ブレーキン ring 48 of wheel unit 45, and rotation of it to axle 46 of back wheel 47 is attained.
As shown in Drawing 29, long hole 122a is formed in sliding member 121. This long hole 122a is formed in a position which meets hole 51a2 in which axles 46 and 46b mentioned above are inserted.
As shown in Drawing 26 and Drawing 29, transmission mechanism 100 has cylindrical members 101, such as a tube, and wire 102 which has inserted in inside of cylindrical member 101 slidably. As shown in Drawing 26 and Drawing 29, both ends of cylindrical member 101 are being fixed to main part 51 of one rear wheel career 50a, and main part 51 of rear wheel career 50b of another side, respectively. As shown in Drawing 26, one end of wire 102 extends across one end of cylindrical member 101, and is being fixed to sliding member 111 of one rear wheel career 50a. If sliding member 111 of one rear wheel career 50a moves to a 1 side along one way, wire 102 will be pulled out from cylindrical member 101 at one rear wheel career 50a side. As shown in Drawing 27, an end of another side of wire 102 extends across an end of another side of cylindrical member 101, and is being fixed to sliding member 121 of rear wheel career 50b of another side. If sliding member 121 of rear wheel career 50b of another side moves to other sides along one way, wire 102 will be pushed out from cylindrical member 101 at one rear wheel career 50a side.
As shown in Drawing 1, Drawing 18, and Drawing 19, transmission mechanism 100 passed the 2nd hind leg element 42 of a pair of hind legs 40, and is prolonged in between one rear wheel career 50a and rear wheel careers 50b of another side. According to such composition, relative displacement to main part 51 along one way of sliding member 121 of one rear wheel career 50a and relative displacement to main part 51 along one way of sliding member 121 of rear wheel career 50b of another side can be interlocked. That is, if sliding member 121 of one rear wheel career 50a moves to a 1 side along one way, sliding member 121 of rear wheel career 50b of another side will come to move to a 1 side along one way. If sliding member 121 of one rear wheel career 50a moves to other sides along one way, sliding member 121 of rear wheel career 50b of another side will come to move to other sides along one way.
And when sliding member 121 of one rear wheel career 50a is located in the 1st holding position according to this embodiment, When sliding member 121 of rear wheel career 50b of another side also comes to be located in the 1st holding position and sliding member 121 of one rear wheel career 50a is located in the 2nd holding position, sliding member 121 of rear wheel career 50b of another side is also located in the 2nd holding position. That is, if while was held and rotation of back wheel 47 of wheel unit (1st wheel unit) 45 is regulated by one rear wheel career 50a, rotation of back wheel 47 of wheel unit (2nd wheel unit) 45 of another side held at rear wheel career 50b of another side will also come to be regulated. Similarly, if while was held and regulation of rotation of back wheel 47 of wheel unit 45 is canceled by one rear wheel career 50a, regulation of rotation of back wheel 47 of wheel unit 45 of another side held at rear wheel career 50b of another side will also come to be canceled.
Next, forelimb pivotal supporting part 27 of forelimb 30 and core member 25 is further explained. In an example mentioned above, forelimb pivotal supporting part 27 explained an example which is supporting a pair of forelimbs 30 which prolong and fall from 互 as estrange gradually. And forelimb unit 29 is constituted as resemble a pair of these forelimbs 30, and forelimb pivotal supporting part 27 which can be removed from base part 26 of core member 25.
And in addition to 1st forelimb unit 29a that consists of forelimb pivotal supporting part 27 which supports a pair of above-mentioned forelimbs 30, and a pair of these forelimbs 30, in this embodiment, it has 1st forelimb unit 29a and 2nd forelimb unit 29b used alternatively. Stroller 10 by which 2nd forelimb unit 29b was incorporated is shown in Drawing 31.
2nd forelimb unit 29b has the 2nd forelimb 30b supported by the 2nd forelimb pivotal supporting part 27b and 2nd forelimb pivotal supporting part 27a removably fixed to base part 26 of core member 25. The 2nd forelimb pivotal supporting part 27a has a pair of forelimb elements 31 put in order and arranged at the cross direction. Gradually, as a pair of forelimb elements 31 approached the cross direction, they are prolonging and falling from core member 25. In an end of a side estranged from core member 25, a pair of forelimb elements 31 are connected mutually. Caster 34 who has a pair of front wheels 35 is attached to a lower end to which a pair of forelimb elements 31 were connected mutually. it is shown in Drawing 33 -- as -- estrangement of a pair of front wheels -- an interval -- estrangement of a pair of back wheels 47 -- as compared with an interval, it is remarkably short. Therefore, it can be said that it constitutes a tricycle if stroller 10 shown in Drawing 33 to which the 2nd forelimb unit 29b was able to be attached is classified functionally. It can be said that it constitutes a four-wheeled vehicle if stroller 10 which was, on the other hand, able to attach the 1st forelimb unit 29a mentioned above is classified functionally.
Thus, when it has two kinds of forelimb units 29a and 29b which can renew one stroller 10, according to a situation of a road surface (sidewall, running surface) stroller 10 comes to run, suitable forelimb units 29a and 29b can be chosen. When stroller 10 comes to run a big concavo-convex road surface top as an example, 1st forelimb unit 29a is chosen suitably. Stroller 10 which has 1st forelimb unit 29a can function as a four-wheeled vehicle, and can raise run neutrality. Thereby, it can be stabilized more safely and more and can be made to run stroller 10 by which infants have ridden. When coming to run a place where stroller 10 was crowded as other examples, the 2nd forelimb unit 29b is chosen suitably. Stroller 10 which has 21st forelimb unit 29b can function as a tricycle, and a small turn of it of stroller 10 can become possible by this, and it can raise the maneuverability drivability of stroller 10.
In forelimb unit 29b shown in Drawing 33, to the 2nd forelimb pivotal supporting part 27b, the 2nd forelimb 30b is supported so that rotation is possible (rocking is possible). That is, an end of a side which supports caster 34 of the 2nd forelimb 30b can make the 2nd forelimb 30b rock to the 2nd forelimb pivotal supporting part 27b in a fold-up state, so that it may move back along the direction of order. In this embodiment, exchange of a part of forelimb linkage mechanism 70 is attained with exchange of forelimb unit 29. Specifically, connection link 81 and forelimb connecting linkage 78 of forelimb linkage mechanism 70 can be exchanged with forelimb unit 29. Rocking of forelimb unit 29 can be interlocked with rocking (rotation of arm member 65) of handle member 60 by exchanging forelimb linkage mechanism 70 in part according to composition of forelimb 30.
By the way, it is preferred that modification energizing member 17 (refer to Drawing 9) which energizes rotation to forelimb pivotal supporting part 27 of forelimb 30 which was folded up from condition of use and turned to a state about 2nd forelimb link 29b as well as forelimb unit 29a mentioned above is incorporated. According to such a modification energizing member 17, forelimb 30 is energized in the fixed direction to forelimb pivotal supporting part 27, and it is lost that forelimb 30 rocks freely to forelimb pivotal supporting part 29. For this reason, by providing this modification energizing member 17, as mentioned above, it not only can make folding operation of body 20 easy, but it can easy-ize replacement work of forelimb unit 29.
Next, sheet 130 attached to body 20 of stroller 10 is explained.
As shown in Drawing 2, sheet 130 which functions as infants' seat or a bed is removably attached to body 20. For example, as shown in Drawing 1, Drawing 2, and Drawing 16, in this embodiment, a pair of rods 131 for fixation are provided in sheet 130, and maintenance hole 12 which receives rod 131 of sheet 130 in handle attaching part 67 of arm member 65 is formed. In maintenance hole 12, a stopping mechanism (not shown) which stops a pin for fixation (not shown) projected from rod 131 is established. And sheet 130 is automatically fixed to body 20 by arranging sheet 130 on body 20, as a pair of rods 131 are inserted in maintenance hole 12. In order to remove sheet 130 from body 20, by operating canceling switch 13 formed in handle support member 67, engaging of clutch of a rod of sheet 130 and maintenance hole 12 of body 20 is canceled, and it is possible to remove sheet 130 from body 20.
In an example shown in Drawing 1, sheet 130 has seat 130a and back 130b connected with seat 130a. In this embodiment, infants who sat on sheet 130 need to turn to the front to be shown in Drawing 1, While being able to attach sheet 130 body 20 (back arrangement), sheet 130 can be carried out for opposite and can also be attached to body 20 so that an operation car (guardian) by which infants operate stroller 10 may be met contrary to a mode shown in Drawing 1 (facing arrangement).
However, sheet 130 shown in Drawing 1 is only an example, and it can use a sheet of various modes so that it may explain below.

Hood 133 mentioned above is being fixed to sheet 135 to illustrate via fixing means 134. 防 132 of the 上述した style can also be attached with sheet 135. When vent 137 is provided in this sheet 135 and 風防 132 is attached, it is possible to perform ventilation with infants' boarding space and the exterior. It is preferred that a filter for purifying air is built into vent 137.
In an example shown in Drawing 36, like Drawing 35, sheet 140 is constituted so that it may function as a bed and a baby carrier. However, sheet 140 is constituted by rattan that outstanding breathability should be secured. Hood 133 is provided on sheet 140.
As for sheet 140 shown in sheet 135 shown in Drawing 35, and Drawing 36, it is preferred that facing arrangement and back arrangement which both mentioned above are constituted possible.
In an example shown in Drawing 33, sheet 142 is formed by attaching a member made of cloth to handle member 60 and arm member 65 of body 20. According to such a mode, stroller 10 can be folded up, without removing sheet 142 from body 20.
It may constitute so that a sheet removed from body 20 may function also as an infant seat which may be fixed to a seat of a car.
A cord member is attached to a sheet and it may enable it to fix to a guardian's body a sheet removed from body 20 in the state on which infants have been sat using a cord member. It may enable it to carry a sheet on the back as an example. According to such a mode, when infants are taken out by a stroller, and infants need to be suddenly taken down from a stroller, it can respond flexibly. A guardian's burden under such a situation is also sharply mitigable.
According to these above embodiments, in condition of use, forelimb 30 and hind legs 40 have prolonged and spread in the cross direction and the direction of order towards a lower part from core member 25 of body 20 located in general in the center. According to stroller 10 with such the body 20, rigidity can be improved effectively and stability under run can be secured. In a fold-up state, it comes to be arranged in a position which an end of the side opposite to approached [by rocking to a core member of forelimb 30 and hind legs 40] in the state where it folded up, more nearly mutually than condition of use in core member 25 of forelimb 30 and hind legs 40. Thereby, a size in a fold-up state can be miniaturized in the direction of order, and the cross direction. That is, according to this embodiment, it can fold up raising the rigidity of stroller 10 and can make a size at the time compact.
According to this embodiment, handle member 60 which has a pair of handle section extending 61 connected to the frame structure which has forelimb 30 and hind legs 40, respectively so that rotation was possible, and flection 62 which connects a pair of handle section extending 61, and which can be crooked is provided. And in the state where it folded up, handle member 60 and hind legs 40 are arranged rather than condition of use by rocking to the frame structure of a pair of handle section extending 61 in a position where an angle made by each handle section extending 61 and hind legs 40 becomes small. In a fold-up state, flection 62 is crooked so that it may project to a side close to the frame structure. According to such a stroller 10, in a fold-up state, while being able to shorten extension length from the frame structure of handle member 60, a cross direction size of handle member 60 can be made small.
According to this embodiment, it is the 1st forelimb unit 29a which may be attached to base part 27, and the 2nd forelimb unit 29b which may be attached to base part 27, and the 1st forelimb unit 29a and the 2nd forelimb unit 29b used alternatively are provided. And when either the 1st forelimb unit 29a or the 2nd forelimb units 29b are used, stroller 10 functions as a tricycle, When another side of the 1st forelimb unit 29a and the 2nd forelimb units 29b is used, stroller 10 functions as a four-wheeled vehicle. According to such a stroller 10, maneuverability drivability or running stability can be raised by choosing either the 1st forelimb unit 29a or the 2nd forelimb units 29b according to a situation of a road surface stroller 10 comes to run.
The frame structure in which stroller 10 has forelimb 30 and hind legs 40 according to this embodiment, Rear wheel career 50 attached to hind legs 40, and the 1st rear wheel unit 45a which is removably supported by rear wheel career 50 and contains the 1st after wheel 47a, It is the 2nd rear wheel unit 45b which is removably supported by rear wheel career 50 and contains the 2nd after wheel 47b, and has the 1st rear wheel unit 45a and the 2nd rear wheel unit 45b used alternatively. And it differs from a path of 1st back wheel 47a, and a path of 2nd back wheel 47b. According to such a stroller 10, maneuverability drivability or running stability can be raised by choosing either the 1st rear wheel unit 45a or the 2nd forelimb units 29b according to a situation of a road surface stroller 10 comes to run.
According to this embodiment, it becomes possible to switch the state where rotation of back wheel 47 was regulated whenever it applied external force towards a 1 side along one way from the other side, and a state which can rotate back wheel 47. According to such a stroller 10, since operation is simple and simple, the state where rotation of back wheel 47 was regulated, and a state which can rotate back wheel 47 can be switched more correctly.
