Specifically, bicycle transmissions generally include front and rear shifting mechanisms that are designed to manipulate the front and rear derailleurs to move the derailleurs laterally on multiple sprockets. A sprocket is usually coupled to the front crank and the rear wheel to transmit the pedaling force of the rider to the rear wheel through a chain.
In the past, shifting devices used included one or more levers mounted on a pivot to wind the inner wires of the control cable. In addition, a rotating handle is used to wind the inner wire of the control cable. The metal wire is connected to the front and rear derailleurs to change the position of the chain on each sprocket. The fabrication and assembly of these existing shifting devices can be very complicated and costly. Moreover, the manipulation of these existing shifting devices may require the rider's hands to be uncomfortable or to move unnaturally. In addition, these existing shifting devices can sometimes be cumbersome.
In view of the above, there is a need for a bicycle shift operating device capable of overcoming the aforementioned problems in the prior art. The present invention can meet this and other requirements of the prior art, which will be apparent to those skilled in the art to which this invention pertains from the present disclosure.
It is an object of the present invention to provide a bicycle shift operating device with a shift lever that moves along a substantially parallel path.
Another object of the present invention is to provide a bicycle shift operating device which is relatively simple to manufacture and assemble and is relatively inexpensive.
Another object of the present invention is to provide a bicycle shift operating device capable of ensuring reliable shifting of the front and rear derailleurs.
The foregoing objects can be basically achieved by providing a bicycle shift operating device including a first operating member, a cable winding mechanism, a follower link, and an operating link. The cable winding mechanism is mounted on a first pivot in a first fixed position, and is configured to be selectively held in one of a plurality of shift positions. A first end of the follow-up link is pivotably coupled to the first operating member, and a second end is mounted on a second pivot shaft in a second fixed position. A first end of the manipulation link is pivotably coupled to the first manipulation member, and a second end is mounted on the first pivot. The operating link is operatively coupled with the cable winding mechanism so that the cable winding mechanism is rotated around the first pivot axis between the shift positions as the first operating member moves.
These objects can also be basically achieved by providing a bicycle shift operating device including a first operating member, a cable winding mechanism, an operating link, and a winding pawl. The cable winding mechanism is mounted on the first pivot shaft and is configured to be selectively held in one of a plurality of shift positions. The first end of the control link is coupled to the first control member, and the second end is mounted on the second pivot. The second pivot is spaced a distance from the first pivot and is parallel to the first pivot. The winding pawl is coupled to the operating link and is operatively engaged with the cable winding mechanism. The manipulation link moves around the second pivot axis in the first rotation direction, so that the cable winding mechanism rotates around the first pivot axis between the shift positions with the movement of the first manipulation member.
These objects can also be substantially achieved by providing a bicycle shift operating device including a first operating member, a second operating member, a cable winding mechanism, and a retaining mechanism. The first manipulation member reciprocates in a first direction. The second manipulation member moves in a second direction substantially parallel to the first direction. The cable winding mechanism is operatively coupled with the first manipulation member for rotation in the first rotation direction, and is also operatively coupled with the second manipulation member for rotation in the second rotation direction opposite to the first rotation direction. The holding mechanism is operatively coupled with the cable winding mechanism to selectively hold the cable winding mechanism in one of a plurality of shift positions.

As shown in FIGS. 4, 6 and 8, the intermediate plate 36 is preferably formed of several thin flat portions that are integrally processed together as a single-piece integral member. Moreover, the intermediate plate 36 is preferably composed of a light rigid material such as a deformed metal thin plate. The intermediate plate 36 is located between the bottom plate 34 and the lever holding plate 38, and basically includes a base portion 36a, a connecting portion 36b, and a lever mounting portion 36c. The base portion 36a is fixedly and non-rotatably coupled to the main / shift mounting plate 32a. The connecting portion 36b extends outward from the base portion 36a. The rod mounting portion 36c is coupled to the free end of the connection portion 36b.
The base portion 36a basically includes a main through hole 36a1, a sub hole 36a2, a positioning hole 36a3, a guide opening 36a4, and a release surface 36a5. A flange 36a6, preferably with a mounting hole 36a7, extends at a right angle from the base portion 36a. The main hole 36a1 is adapted to receive the main fixing bolt 40, and the auxiliary hole 36a2 is adapted to receive the auxiliary fixing bolt 42.

The holding mechanism 30 is coupled to the positioning holes 36a3 and the holes 34b so that the bottom plate 34 can also be non-rotatably coupled to the main mounting portion 32 through the base portion 36a, which will be discussed below.
The guide opening 36a4 is adapted to receive a part of the manipulation mechanism 28, which will be discussed in more detail below. The release surface 36a5 is adapted to selectively engage a portion of the manipulation mechanism 28, which will also be described below. The flange 36 a 6 partially extends through the T-shaped opening 34 e of the bottom plate 34 so as to non-rotatably couple the bottom plate 34 to the intermediate plate 36. Since the flange 36a6 has a stepped configuration, the flange 36a6 also functions as a cushion between the bottom plate 34 and the intermediate plate 36. The mounting hole 36a7 houses a fastener 45 to couple the control cable 21 thereto.
The lever mounting portion 36c includes first and second mounting flanges 36c1 and 36c2. The mounting flanges 36c1 and 36c2 include holes 36c3 and 36c4, respectively. The holes 36c3 and 36c4 are adapted to receive a part of the operating mechanism 28, which will be discussed in more detail below. The connecting portion 36b extends between the rod mounting portion 36c and the base portion 36a so that the rod mounting portion 36c is spaced outward from the base portion 36a.
As shown in FIGS. 4, 6 and 9, the lever holding plate 38 is preferably a thin flat member. The lever holding plate 38 is preferably composed of a light rigid material such as a thin metal plate. The lever holding plate 38 is located on the side of the intermediate plate 36 opposite to the bottom plate 34. Thus, the position of the lever holding plate 38 is farthest from the main mounting portion 32. The lever holding plate 38 is fixedly and non-rotatably coupled to the main / shift plate 32 a by fixing bolts 40 and 42. The lever holding plate 38 basically includes a main support portion 38a and an extension portion 38b.
The main support portion 38a has a main hole 38a1, a pair of opposed auxiliary holes 38a2, and a pair of opposed holding holes 38a3. The main hole 38a1 is adapted to receive the main fixing bolt 40. In this embodiment, the auxiliary hole 38a2 is not used. However, one of the auxiliary holes 38a2 is used in the rear shift operating device 22, which will be discussed later. The pair of holding holes 38a3 is adapted to receive the protruding portion of the main nut plate 41 to prevent the main fixing bolt 40 from being loosened after the parts of the mounting assembly 24 are coupled together.
The extension portion 38b includes a secondary hole 38b1 and a pair of holding holes 38b2. The auxiliary hole 38b1 is adapted to receive the auxiliary fixing bolt 42. The holding hole 38b2 is adapted to receive the protruding portion of the auxiliary bolt plate 43 to prevent the auxiliary fixing bolt 42 from being loosened after the various parts of the mounting assembly 24 are coupled together. Thus, the lever holding plate 38, the intermediate plate 36, the bottom plate 34, and the main / shift plate 32a are fixedly and non-rotatably coupled together to form a housing or a mounting assembly 24.
Referring to Figures 4, 6, and 10-14, the winding mechanism 26 will now be discussed in more detail. The winding mechanism 26 is mounted on the main fixing bolt 40 between the bottom plate 34 and the intermediate plate 36 of the mounting assembly 24. The winding mechanism 26 basically includes a cable winding member 52, a ratchet member 54, a main biasing member 56, and a unit pad 58. In the illustrated embodiment, the winding member 52 and the ratchet member 54 are preferably separate members that are non-rotatably connected together. The main biasing member 56 is preferably a torsion spring that normally biases the winding member 52 and the ratchet member 54 in a predetermined rotation direction, such as a CCW counterclockwise direction shown in FIG. 4. The winding mechanism 26 is operatively coupled with the manipulation mechanism 28 and the holding mechanism 30 to selectively retain the winding member 52 in one of a plurality of shift positions.
The winding member 52 is preferably a step-shaped member integrally processed as a single-piece integral member. Moreover, the winding member 52 is preferably composed of a light rigid material such as a hard plastic. The winding member basically includes a winding portion 52a and a protruding portion 52b. A central through opening 52a1 extends through the winding portion 52a and the protruding portion 52b, and is adapted to receive the main fixing bolt 40 therein. In this way, the winding member 52 is coupled to the mounting assembly 24 for rotation about the main fixing bolt 40. The ratchet member 54 is preferably non-rotatably coupled to the winding member 52 between the winding member 52 and the intermediate plate 36. Thus, the ratchet member 54 rotates with the winding member 52. As described below, the rotational movement of the winding member 52 is controlled by the ratchet member 52.
The winding portion 52a basically has a cable mounting section 52a2, a winding surface 52a3, and a spring receiving recess 52a4. The cable installation section 52a2 conventionally includes a through opening adapted to receive the inner wire of the control cable 21 and a recess adapted to receive the connector or abutment of the inner wire of the control cable 21. The winding surface 52a3 is a curved groove-shaped surface extending outward from the cable installation section 52a2 along the circumference. The spring accommodating recess 52a4 is a generally annular recess, and its diameter is larger than the central through opening 52a1. Moreover, the spring receiving recess 52a4 includes a cutout or notch 52a5 suitable for receiving one end of the spring 56, which will be discussed later. Preferably, the radial width of the spring-receiving recess 52a4 is large enough to accommodate a portion of the main spring 56, which will also be discussed in more detail below. The winding portion 52a also preferably includes a stepped groove 52a6 adapted to receive a part (not shown) of the indicating mechanism 46.
The protruding portion 52b basically includes a plurality of large splines 52b1 and a plurality of small splines 52b2, which are adapted to be non-rotatably engaged with the ratchet member 54. The large spline 52b1 is located on the side of the central through opening 52a1 opposite to the small spline 52b2. Furthermore, the orientation of the splines 52b1 and 52b2 allows the ratchet member 54 to have a specific configuration for proper engagement with the manipulation mechanism 28 and the holding mechanism 30, which will be discussed below.
The ratchet member 54 is preferably a thin flat member. Preferably, the ratchet member 54 is composed of a light rigid material such as a thin metal plate. The ratchet member 54 basically includes a central opening 54a with a keyway, an outer manipulation surface 54b, and an outer positioning surface 54c. The keyed opening 54a is adapted to receive the protruding portion 52b of the winding member 52 so as to non-rotatably couple the ratchet member 54 to the winding member 52 in a predetermined orientation. In other words, the opening 54a cooperates with the large spline 52b1 and the small spline 52b2 of the protruding portion 52b so that the winding member 52 rotates with the ratchet member 54 like a single member.
The manipulation surface 54b is adapted to engage a portion of the manipulation mechanism 28, which will be discussed below. More specifically, the manipulation surface 54b includes a plurality of (three) grooves 54b1, which are designed to selectively engage a portion of the manipulation mechanism 28. The positioning surface 54c is adapted to engage a portion of the holding mechanism 30 (which will also be discussed later) to selectively hold and retain the ratchet member 54 and the winding member 52 in one of a plurality of shift positions. More specifically, the positioning surface 54 c includes a plurality of (three) projections or teeth 54 c 1 that engage a portion of the holding mechanism 30. The ratchet member 54 also preferably includes a pair of stops 54d and 54e. Specifically, the stopper 54d is a stationary stopper and the stopper 54e is a completely displaced stopper. The stoppers 54d and 54e are selectively engaged with portions of the holding mechanism 30 so as to control the movement of the winding member 52 and the ratchet member 54.
As best seen in FIG. 4, the biasing member 56 is preferably a torsion spring, which is used to apply a urging force to the winding member 52 and the ratchet member 54 to rotate about the main fixing bolt 40. The biasing member (spring) 56 basically includes a first end 56a, a second end 56b, and a coiled portion 56c extending between the first end 56a and the second end 56b. The first end 56a is placed in the spring mounting slot 34c of the bottom plate 34, and the second end 56b is placed in a notch or cutout 52a5 extending from the spring receiving recess 52a4 of the winding member 52. The coiled portion 56c is partially received in the spring receiving recess 52a4. The unit gasket 58 is placed in the center through-opening 52a1 of the winding member 52.
The unit pad 58 is preferably a tubular member made of a light rigid material, one end of which is in contact with the lower surface of the bottom plate 34 and the other end is in contact with the intermediate plate 36. The spring 56 is adapted to bias the winding member 52 in a counterclockwise CCW direction when viewed from above in FIG. 4 under normal circumstances. In this way, the operating mechanism 28 moves the winding member 52 in the clockwise direction against the urging force of the main biasing member 56 through the ratchet member 54. More specifically, the manipulation mechanism 28 preferably moves the winding member 52 to one of three predetermined shift positions, which will be discussed later. The holding mechanism 30 selectively holds the winding member 52 and the ratchet member 54 in one of three shift positions, which will also be discussed later.
Referring to Figures 4, 6 and 15-27, the steering mechanism 28 will now be discussed in more detail. The manipulation mechanism 28 basically includes a first manipulation member 60, a second manipulation member 62, a manipulation link 64, and a follow-up link 66. The first operating member 60 forms a four-link mechanism that controls the movement of the first operating member 60 together with the operating link 64, the follower link 66 and the mounting assembly 24. More specifically, the first manipulation member 60 is pivotably coupled to the manipulation link 64 and the follower link 66 so as to move along the first arc A1. The operating link 64 is pivotally coupled to the main fixing bolt 40, and the follower link 66 is pivotally coupled to the auxiliary fixing bolt 42. The curvature of the first arc A1 is relatively gentle so that the first manipulation member 60 can move substantially along a straight line, as can be seen most clearly in FIG. 32.
The control link 64 preferably has a pawl mechanism 68 operatively coupled thereto. The pawl mechanism 68 is adapted to engage the manipulation surface 54b of the ratchet member 54 when the first manipulation member 60 is pushed or moved to a shift position by a rider. In this way, when the first manipulation member 60 moves along the arc A1 in a substantially straight direction, the manipulation link 64 also moves so that the pawl mechanism 68 overcomes the urging force of the biasing member 56 and rotates the ratchet member 54 to a shift position. . In this way, the winding member 52 is also rotated to pull the inner wire of the shift cable 21 and shift the front derailleur 15 to one of its shift positions.
When the first manipulation member 60 is moved back to the normal rest position, the pawl mechanism 68 is engaged with the release surface 36 a 5 of the intermediate plate 36 to disengage the pawl mechanism from the ratchet member 54. However, the holding mechanism 30 is engaged with the ratchet member 54 to hold the winding member 52 and the ratchet member 54 in the new shift position against the urging force of the spring 56. In the illustrated embodiment, the movement of the first manipulation member 60 causes the winding member 52 to be shifted only once from one shift position in one rotation direction to the next adjacent shift position.
The second manipulation member 62 is operatively coupled with the holding mechanism 30 to selectively release the ratchet member 54 and the winding member 52. In other words, the rider pushes or moves the second manipulation member 62 to disengage the holding mechanism 30 from the ratchet member 54, and this causes the winding member 52 and the ratchet member 54 to be urged by the spring 56 Spin. The holding mechanism 30 is adapted so that the winding member 52 and the ratchet member 54 can only rotate through one shift position when the second operating member 62 is pushed once. In other words, the ratchet member 54 is engaged with the holding mechanism 30 after turning through a shift position. Thus, in the illustrated embodiment, the movement of the second manipulation member 62 causes the winding member 52 to shift from only one shift position in the other rotation direction opposite to the rotation direction generated when the first manipulation member 60 moves Once to the next adjacent shift position.
As best seen in FIGS. 4 and 15, the first manipulation member 60 is a thin flat member. The first manipulation member 60 is preferably composed of a light rigid material such as a deformed metal sheet. The first manipulation member 60 basically includes an actuating portion 60a and a link portion 60b. The link portion 60b is preferably perpendicular to the actuation portion 60a. The link portion 60b includes a pair of holes 60b1 and 60b2, which are adapted to receive the upper ends of a pair of pivot pins 69 and 70, respectively. The pivot pin 69 is pivotally coupled to the manipulation link 64, and the pivot pin 70 is pivotally coupled to the follower link 64 to move the first manipulation member 60 along the first arc A1. The actuation portion 60a may have a button 73 coupled to it, as shown in FIG. 2, and actuated or pushed by the thumb or other fingers of the cyclist.
The second manipulation member 62 is preferably a thin flat member composed of a light rigid material such as a deformed metal sheet. The second manipulation member 62 is slidably and pivotably mounted on the auxiliary fixing bolt 42. More specifically, the second manipulation member 62 is slidably and pivotably mounted on the pad 63, and the pad 63 is mounted on the second fixing bolt between the second manipulation member 62 and the follower link 66. 42 on. The second manipulation member 62 basically includes a long opening 62a, an actuating flange 62b, and a release flange 62c. The upper end of the pad 63 is housed in the long opening 62a. The release flange 62 c is received in the guide opening 36 a 4 of the intermediate plate 36 so as to control the movement of the second manipulation member 62 together with the fixed pad 63.
The second operating member 62 is actuated by a toggle lever 71 that is pivotably coupled to the mounting flanges 36c1 and 36c2 of the intermediate plate 36. More specifically, the toggle lever 71 is operatively coupled with the actuating flange 62b so that when the rider pushes the toggle lever 71 with a thumb or other finger, the second operating member 62 follows the second arc A2 Moving in a roughly straight direction is best seen in Figure 38. More specifically, the release flange 62c is housed in the guide opening 36a4 of the middle plate 36, and the upper end of the gasket 63 is housed in the long opening 62a so as to move the actuating flange 62b along the arc A2.
The arc A2 is substantially parallel to the arc A1, and both arcs preferably have a large radius of curvature so as to enable a substantially straight parallel movement between the first and second manipulation members 60 and 62. The return biasing member or spring 72 is operatively coupled between the second manipulation member 62 and the intermediate plate 36. In this way, when the rider releases the toggle lever 71, the second manipulation member 62 and the toggle lever 71 are reset to the normal rest position. The guide opening 36a4 and the release flange 62c of the intermediate plate 36 are adapted to selectively engage / actuate the holding mechanism 30, which will be discussed below.
The control link 64 is preferably a thin flat stepped member composed of a light rigid material such as a deformed metal sheet. More specifically, the manipulation link 64 basically includes a manipulation portion 64a and a coupling portion 64b. As described above, the manipulation link 64 is pivotally coupled to the main fixing bolt 40 and the pivot pin 69, and it is pivotally coupled to the first manipulation member 60. The operating portion 64a basically includes a main hole 64a1, a pawl mounting hole 64a2, a protruding portion 64a3, a cutout 64a4, and a spring mounting hole 64a5.
The gasket 65 is attached to the main fixing bolt 40. The pad 65 has a stepped outer surface, and a bottom end thereof is mounted in the main hole 64 a1 of the control link 64. The upper end of the gasket 65 is in contact with the middle plate 36 and surrounds the main hole 36 a1 of the middle plate 36. In this way, the operation portion 64 a of the operation link 64 is spaced a certain distance from the intermediate plate 36 and is rotatably mounted on the pad 65.
The pawl mechanism 68 is coupled to the pawl mounting hole 64a2, and basically includes a pawl pivot pin 74, a pawl spring 76, and a pawl member 78. The lower end of the pawl pivot pin 74 is mounted in a pawl mounting hole 64 a 2 of the operation link 64. The pawl member 78 is mounted on the upper end of the pawl pivot pin 74, and the pawl spring 76 biases the pawl member 78 relative to the operating link 64 under normal circumstances. Specifically, the pawl spring 76 has an upper end 76 a coupled to the pawl member 78, a lower end 76 b housed in a spring mounting hole 64 a 5 of the operating link 64, and a pawl pivot pin 74 Coiled portion 76c. The protrusion 64 a3 and the cutout 64 a4 of the manipulation link 64 function as a stop member or a motion control member of the manipulation link 64. More specifically, the protrusions 64 a3 and the cutouts 64 a4 are adapted so that portions of the steering link 64 do not interfere with the movement of other components of the front shift manipulation device 20 and / or control the movement of the steering link 64.
The pawl member 78 basically includes a mounting portion 78a and a pawl portion 78b. The mounting portion 78 a is thinner than the pawl portion 78 b and is received on the pawl pivot pin 74. The pawl portion 78b is adapted to contact the manipulation surface 54b of the ratchet member 54 as selected. Specifically, when the manipulation link 64 is driven by the first manipulation member 60, the pawl portion 78 b is engaged with one of the grooves 54 b 1 of the manipulation surface 54 b to rotate the ratchet member 54 and the winding member 52 about the main fixing bolt 40. . However, when the first manipulation member 60 and the manipulation link 64 are in the normal rest position, the pawl portion 78 b is in contact with the outer release surface 36 a 5 of the intermediate plate 36.
In other words, the shape of the outer release surface 36a5 is adapted to keep the pawl portion 78b out of engagement with the groove 54b1 of the manipulation surface 54b when the manipulation link 64 and the first manipulation member 60 are in their normal rest positions. In this way, if the second manipulation member 62 is actuated by the toggle lever 71, for example, if the holding mechanism 30 is released as described below, the ratchet member 54 and the winding member 52 are rotated by the urging force of the main biasing member 56 .
The coupling portion 64b of the manipulation link 64 is offset from the manipulation portion 64a and basically includes a coupling hole 64b1. The coupling hole 64 b1 is adapted to receive a lower end of a pivot pin 69 pivotably coupled to the first manipulation member 60.
Referring again to FIGS. 4 and 19-21, the follower link 66 basically includes a manipulation portion 66a, a coupling portion 66b, and a protrusion 66c. The follower link 66 is preferably a step-shaped thin flat member composed of a light rigid material such as a deformed metal sheet. The manipulation portion 66 a is pivotably coupled to the pivot pin 70, and the pivot pin 70 is pivotally coupled to the first manipulation member 60. The coupling portion 66 b is pivotally coupled to the auxiliary fixing bolt 42 through a gasket 63. The manipulation portion 66a is offset from the coupling portion 66b. The protruding portion 66c extends upward from the coupling portion 66b, and is adapted to receive one end of the return biasing member (spring) 79.
More specifically, the manipulation portion 66a includes a hole 66a1 adapted to rotatably receive the lower end of the pivot pin 70, and the coupling portion 66b includes a hole 66b1 adapted to receive the lower end of the pad 63. One end of the reset biasing member 79 is coupled to the protruding portion 66c, and the other end is coupled to the intermediate plate 36 so as to push the follower link 66 to a rest position under normal circumstances. In this way, under normal circumstances, the first operating member 60 and the first operating link 64 are also biased to the rest position under the action of the reset biasing member (spring) 79, because these members constitute the three links of the four-link mechanism assembly. Pole.
Referring to Figures 4, 6, and 28, the holding mechanism 30 will now be discussed in more detail. The holding mechanism 30 basically includes a holding pivot pin 80, a holding biasing member 82, and a locking member 84. The holding pivot pin 80 is coupled to the bottom plate 34 and the middle plate 36. The lock member 84 is rotatably mounted on the holding pivot pin 80. The holding biasing member 82 biases the locking member 84 to a predetermined position under normal circumstances. Structural configuration adapted to the locking member 84 with the positioning surface 54c of the ratchet member 54 engages. Moreover, the structural configuration of the locking member 84 is also adapted to be engaged with the release flange 62 c of the second manipulation member 62 as selected.
More specifically, the upper end of the holding pivot pin 80 is received in the mounting hole 34 b of the bottom plate 34, and the lower end is received in the positioning hole 36 a 3 of the intermediate plate 36. Thus, the holding pivot pin 80 and the bottom plate 34 cannot be moved relative to the main mounting portion 32. The locking member 84 is placed on the lower end of the holding pivot pin 80 adjacent to the guide opening 36 a 4 of the intermediate plate 36. The upper end of the biasing member 82 is engaged with the protruding section 34d of the bottom plate 34, and the lower end is engaged with the locking member 84 so as to bias the locking member 84 in a predetermined direction under normal circumstances.
The locking member 84 basically includes a first stopper portion 84a, a second stopper portion 84b, a center hole 84c, a spring receiving recess 84d, and an actuating projection 84e. The lower end of the holding pivot pin 80 is accommodated in the hole 84 c so as to place the locking member 84 between the bottom plate 34 and the middle plate 36. The first and second stopper portions 84 a and 84 b are disposed on opposite sides of the teeth 54 c 1 of the ratchet member 54. The spring receiving recess 84d is adapted to receive the lower end of the biasing member 82. The actuating protrusion 84e is located adjacent to the release flange 62c of the second manipulation member 62 housed in the guide opening 36a4.
When the second manipulation member 62 is actuated by the toggle lever 71, the release flange 62 c is engaged with the actuation protrusion 84 e so that the lock member 84 is rotated against the biasing force of the spring 82. This disengages the first stopper portion 84a from the positioning surface 54c. Thus, the ratchet member 54 and the winding member 52 are rotated to a shift position by the biasing force of the main biasing member or the spring 56. When the toggle lever 71 is released, the lock member 84 rotates under the biasing force of the spring 82 to engage with the next tooth of the positioning surface 54c so as to maintain the ratchet member 54 and the winding member 52 at a desired shift position. .
The operation of the front shift operating device 20 will now be discussed in more detail with reference to FIGS. 4, 6, and 29-40. When the cyclist wishes to shift the front derailleur 15 and the chain C from the smaller front sprocket FS to the larger front sprocket FS, the cyclist pushes the first manipulation member 60 with the thumb or other fingers. The first manipulation member 60 moves to the shift position along the arc A1. This movement of the first operating member 60 will cause the operating link 64 and the follower link 66 to rotate about the main and auxiliary fixing bolts 40 and 42 respectively. When the operating link 64 is rotated around the main fixing bolt 40, the pawl mechanism 68 moves together with the operating link 64.
When the pawl mechanism 68 moves, the pawl member 78 is disengaged from the release surface 36 a 5 of the intermediate plate 36. The pawl member 78 is then engaged with the ratchet member 54 to rotate the ratchet member 54 and the winding member 52 to a shift position. When the ratchet member is moved from one shift position to an adjacent next shift position by the pawl mechanism 68, the lock member 84 is disengaged from its corresponding tooth 54c1 and is engaged with the next corresponding tooth 54c1. Specifically, when the ratchet member 54 is moved between the two shift positions, the lock member 84 is disengaged from the teeth 54c1 and then re-engaged to hold the ratchet member 54 at the next shift position.
When the rider releases the first manipulation member 60, the first manipulation member 60 moves back to its normal rest position along the first arc A1. This movement of the first operating member 60 will cause the operating link 64 and the follower link 66 to rotate about the main and auxiliary fixing bolts 40 and 42 respectively. The control link 64 and the follower link 66 rotate until they return to their normal rest positions. The pawl mechanism 78 moves together with the operating link 64. Thus, the pawl member 78 is moved back to the position engaged with the release surface 36 a 5 so that the pawl member 78 is disengaged from the manipulation surface 54 b of the ratchet member 54. However, the ratchet member 54 is held in its shift position by the lock member 84. If the cyclist wants to shift from the smaller front sprocket FS to the larger front sprocket FS again, he pushes the first operating member 60 along the first arc A1 again and repeats the above process.
If the cyclist wants to shift the front derailleur 15 and the chain C from the larger front sprocket FS to the smaller front sprocket FS, the cyclist pushes the toggle lever 71 with his thumb or other fingers. When the toggle lever 71 is actuated by the rider, the second operating member 62 moves from the normal rest position to the shift position along the second arc A2. Specifically, the movement of the second manipulation member 62 is controlled by the guide opening 36 a 4 of the intermediate plate 36 and the washer 63 coupled to the auxiliary fixing bolt 42. When the second manipulation member 62 is moved to the shift position, the release flange 62 c is engaged with the lock member 84. The lock member 84 rotates against the biasing force of the spring 82 to disengage from the teeth 54c1 of the ratchet member 54. The ratchet member 54 can then be rotated by the biasing force of the main biasing member or the spring 56.
The locking member 84 will then engage the next adjacent tooth 54c1 when the second manipulation member 62 is released. Specifically, when the rider pushes the shift lever 71, the lock member 84 is disengaged from the tooth 54c1. However, when the rider subsequently releases the toggle lever 71, the second operating member 62 will return to its normal rest position under the biasing force of the return spring 72. In this way, the release flange 62c will release the lock member 84. In other words, the second manipulation member 62 is designed as a structure that can be relatively quickly dialed and released by a cyclist. Then, the lock member 84 is non-rotatably engaged with the next adjacent tooth 54c1 of the ratchet member 54 to complete the displacement from the larger front sprocket FS to the smaller front sprocket FS. This process can be repeated if a cyclist is required.
Of course, if the chain C is already on the smallest front sprocket FS, the stopper between the locking member 84 and the ratchet member 54 will prevent it from disengaging from the tooth 54c1. Therefore, if the rider pushes the shift lever 71 while the front derailleur 15 is located on the smallest front sprocket FS, the shift will not be performed. Similarly, if the front derailleur 15 is at its highest position and the chain C is placed on the largest front sprocket FS, the first operating member 60 will not be able to shift gears due to the stopper between the lock member 84 and the ratchet member 54 . This way, there is no shifting in this case.
Rear gearshift
Referring to Figures 3 and 5, the rear shifter 22 will now be discussed in more detail. In addition to changes to certain parts of the rear gear shifter to provide the rear gear shifter 22 with more shift positions than the front gear shifter 20, the rear gear shifter 22 and the front gear shifter The device 20 is substantially the same. Specifically, since the rear derailleur 17 has more shift positions than the front derailleur 15, the rear shift operation device 22 is designed to include more shift positions than the front shift operation device 20. However, the manipulation member used by the rear shift manipulator 22 has the same or almost the same stroke as the front shift manipulator 20, which will be discussed below. In other words, the rear shifter 22 is suitable for use with the rear derailleur 17 and is designed to shift between a plurality of rear sprocket RSs having a greater number than the front sprocket FS.
The rear shift operating device 22 basically includes a mounting assembly 124, a winding mechanism 126, an operating mechanism 128, and a holding mechanism 130, which are coupled together so that the rear derailleur 17 and the chain of the transmission train or transmission 14 C is shifted between each rear sprocket RS. In the embodiment shown, the transmission 14 preferably has more than three rear sprockets RS associated with it. More specifically, in the embodiment shown, the transmission 14 preferably has nine rear sprockets RS. In this way, the rear shift operating device 22 also preferably has more than three shift positions. More specifically, the rear shift operating device 22 preferably has nine shift positions. In any case, the rear shift operating device 22 preferably has a plurality of shift positions, the number of which corresponds to the number of shift positions of the rear derailleur 17. Of course, by reading this disclosure, it will be apparent to those of ordinary skill in the art to which the present invention pertains that the rear derailleur 17 and the rear shift operating device 22 can be designed to have different numbers of Gear position.
The winding mechanism 126, the manipulation mechanism 128, and the holding mechanism 130 are coupled to the mounting assembly 124. The winding mechanism 126 is controlled by the operating mechanism 128 and the holding mechanism 130 so as to selectively retain the rear derailleur 17 in one of a plurality of shift positions through the control cable 23. More specifically, the manipulation mechanism 128 and the holding mechanism 130 control the rotation of the winding mechanism 126 to selectively hold the winding mechanism 126 in one of a plurality of shift positions. In this way, the inner wire of the control cable 23 and the rear derailleur 17 are also maintained at one of a plurality of shift positions as selected. The inner wire of the rear control cable 23 is coupled to the winding mechanism 126, so the rotation of the winding mechanism 126 will tighten or loosen the inner wire of the control cable 23 so that the rear derailleur 17 is on each rear sprocket. Actuate / move / shift between RS.
The mounting assembly 124 basically includes a plurality of fixing members that are coupled together to form a shifter housing that supports the winding mechanism 126, the manipulation mechanism 128, and the holding mechanism 130. More specifically, the mounting assembly 124 basically includes a main mounting portion 132, a bottom plate 134, an intermediate plate 136, and a lever holding plate 138. The bottom plate 134, the intermediate plate 136, and the rod holding plate 138 are substantially fixedly coupled to the main mounting portion 132 by a main fixing bolt 140 (first fixing pivot) and a sub fixing bolt 142 (fixing pivot), which are preferably parallel to each other. In order to form the gearshift housing. Various other parts of the rear shift operating device 22 (ie, the parts of the winding mechanism 126, the operating mechanism 128, and the holding mechanism 130) are movably or immovably coupled to the mounting assembly 124, which will be described in more detail below. discuss.

In the illustrated embodiment, the brake lever 133 is pivotably coupled to the brake lever mounting bracket 132 c of the main mounting portion 132. The brake lever 133 is operatively coupled to the rear brake 19b through a bowden-type brake wire in a conventional manner. Preferably, the main / shift mounting plate 132a, the handlebar mounting bracket 132b, and the brake lever mounting bracket 132c are integrally processed together as a single-piece integral member coupled to the handlebar 13 through the mounting bracket 132b. Thus, it is preferable to provide an integrated rear shift / brake operating device 22. The main mounting portion 132 is preferably composed of a light rigid material such as cast aluminum. Of course, any suitable material can be used if needed and / or desired.
The bottom plate 134, the middle plate 136, and the holding plate 138 are preferably spaced from each other by fixedly coupling to the main / shift mounting plate 132a by fixing bolts 140 and 142 so as to accommodate the winding mechanism 126, the manipulation mechanism 128, and the holding mechanism 130 therebetween. Individual parts. More specifically, the main / shift mounting plate 132a includes a main through hole 132a1 and a blind threaded hole 132a2 for mounting the fixing bolts 140 and 142 therein, respectively. The cover 144 and the indicating mechanism 146 are also preferably fixedly coupled to the main / shift mounting plate 132a. However, the cover 144 and the indicating mechanism 146 are more common. Therefore, the cover 144 and the indicating mechanism 146 will not be discussed and / or shown in detail herein. Moreover, the cover 144 and the indicating mechanism 146 have been omitted in some figures for the sake of clarity. In any case, the indicating mechanism 146 is preferably operatively coupled with the shift operating device 22 to indicate different shift positions in a conventional manner.
As shown in FIGS. 5 and 41, the base plate 134 is a relatively thin, flat member. The bottom plate 134 is preferably composed of a light rigid material such as a thin metal plate.

The main through hole 134a is adapted to receive the main fixing bolt 140 and the mounting hole 134b is adapted to accommodate a portion of the holding mechanism 130. Specifically, the holding mechanism 130 is coupled to the positioning mounting hole 134b and the intermediate plate 136 to prevent the bottom plate 134 from rotating relative to the main mounting portion 132, which will be discussed below. In addition, a part of the intermediate plate 136 partially extends through the T-shaped opening 134e to prevent the bottom plate 134 from rotating and serves as a cushion, which will also be discussed below.

An auxiliary hole 136a8 is interposed between the main hole 136a1 and the release surface 136a5. The main hole 136a1 is adapted to receive the main fixing bolt 140, and the auxiliary hole 136a2 is adapted to receive the auxiliary fixing bolt 142. Thus, the base portion 136a is non-rotatably coupled to the main mounting portion 132. The holding mechanism 130 is coupled to the positioning holes 136a3 and the holes 134b so that the bottom plate 134 can also be non-rotatably coupled to the main mounting portion 132 through the base portion 136a, which will be discussed below.

The flange 136 a 6 partially extends through the T-shaped opening 134 e of the bottom plate 134 so as to non-rotatably couple the bottom plate 134 to the intermediate plate 136. Since the flange 136a6 has a stepped configuration, the flange 136a6 also functions as a cushion between the bottom plate 134 and the middle plate 136. The mounting hole 136a7 receives a fastener 145 to couple the control cable 23 thereto. The auxiliary hole 136a8 is adapted to receive the pivot pin 148 (second fixed pivot). A part of the manipulation mechanism 128 is rotatably mounted or coupled to the pivot pin 148, which will be described later.

The main hole 138a1 is adapted to receive the main fixing bolt 140. In this embodiment, one auxiliary hole 138a2 is used to receive the lower end of the pivot pin 148. In other words, the lever holding plate 138 is the same as the lever holding plate 38, except that in the rear shift operating device 22, a pivot pin 148 is partially accommodated in one auxiliary hole 138a2. The pair of retaining holes 138a3 is adapted to receive the protruding portion of the main nut plate 141 to prevent the main fixing bolt 140 from being loosened after the various parts of the mounting assembly 124 are coupled together.
The extension portion 138b includes a secondary hole 138b1 and a pair of holding holes 138b2. The auxiliary hole 138 b1 is adapted to receive the auxiliary fixing bolt 142. The holding hole 138b2 is adapted to receive the protruding portion of the auxiliary bolt plate 143 to prevent the auxiliary fixing bolt 142 from being loosened after the various parts of the mounting assembly 124 are coupled together. In this way, the lever holding plate 138, the intermediate plate 136, the bottom plate 134, and the main / shift plate 132a are fixedly and non-rotatably coupled together to form a housing or a mounting assembly 124.
5 and 44-47, the winding mechanism 126 will now be discussed in more detail. The winding mechanism 126 is mounted on the main fixing bolt 140 between the bottom plate 134 and the intermediate plate 136 of the mounting assembly 124. The winding mechanism 126 basically includes a cable winding member 152, a ratchet member 154, a main biasing member 156, and a unit pad 158. In the illustrated embodiment, the winding member 152 and the ratchet member 154 are preferably separate members that are non-rotatably connected together. The main biasing member 156 is preferably a torsion spring that normally biases the winding member 152 and the ratchet member 154 in a predetermined rotation direction, such as a clockwise CW bias shown in FIG. 5. The winding mechanism 126 is operatively coupled with the manipulation mechanism 128 and the holding mechanism 130 to selectively retain the winding member 152 in one of a plurality of shift positions.
The winding member 152 is preferably a step-shaped member integrally processed as a single-piece integral member. Moreover, the winding member 152 is preferably composed of a light rigid material such as a hard plastic. The winding member basically includes a winding portion 152a and a protruding portion 152b. A central through opening 152a1 extends through the winding portion 152a and the protruding portion 152b, and is adapted to receive the main fixing bolt 140. In this way, the winding member 152 is coupled to the mounting assembly 124 for rotation about the main fixing bolt 140. The ratchet member 154 is preferably non-rotatably coupled to the winding member 152 between the winding member 152 and the intermediate plate 136. Thus, the ratchet member 154 rotates with the winding member 152. As described below, the rotational movement of the winding member 152 is controlled by the ratchet member 152.
The winding portion 152a basically has a cable mounting section 152a2, a winding surface 152a3, and a spring receiving recess 152a4. The cable installation section 152a2 includes a through opening adapted to receive the inner wire of the control cable 23 and a recess adapted to receive the connector or abutment of the inner wire of the control cable 23 in a conventional manner. The winding surface 152a3 is a curved groove-shaped surface extending outward from the cable installation section 152a2 along the circumference. The spring receiving recess 152a4 is a generally annular recess, and its diameter is larger than the central through opening 152a1. Further, the spring receiving recess 152a4 includes a cutout or notch 152a5 suitable for receiving one end of the spring 156, which will be discussed later. Preferably, the radial width of the spring-receiving recess 152a4 is large enough to accommodate a portion of the main spring 156, which will also be discussed in more detail below. The winding portion 152a also preferably includes a stepped groove 152a6 adapted to receive a part (not shown) of the indicating mechanism 146.
The protruding portion 152b basically includes a plurality of large splines 152b1 and a plurality of small splines 152b2, which are adapted to be non-rotatably engaged with the ratchet member 154. The large spline 152b1 is located on the side of the central through opening 152a1 opposite to the small spline 152b2. Moreover, the orientation of the splines 152b1 and 152b2 allows the ratchet member 154 to have a specific configuration for proper engagement with the manipulation mechanism 128 and the holding mechanism 130, which will be discussed below.
The ratchet member 154 is preferably a thin flat member. Preferably, the ratchet member 154 is made of a light rigid material such as a thin metal plate. The ratchet member 154 basically includes a central opening 154a with a keyway, an outer manipulation surface 154b, and an outer positioning surface 154c. The opening 154a is adapted to receive the protruding portion 152b of the winding member 152 so as to non-rotatably couple the ratchet member 154 to the winding member 152 in a predetermined orientation. In other words, the opening 154a cooperates with the large spline 152b1 and the small spline 152b2 of the protruding portion 152b so that the winding member 152 and the ratchet member 154 rotate together as a single member.
The manipulation surface 154b is adapted to engage a portion of the manipulation mechanism 128, which will be discussed below. More specifically, the manipulation surface 154b includes a plurality (nine) of grooves 154b1, which form teeth that are designed to engage a portion of the manipulation mechanism 128 as selected. The positioning surface 154c is adapted to engage a portion of the retaining mechanism 130 (which will also be discussed later) to selectively retain and retain the ratchet member 154 and the winding member 152 in one of a plurality of shift positions. More specifically, the positioning surface 154 c includes a plurality (nine) of protrusions or teeth 154 c 1 that are engaged with a part of the holding mechanism 130. Thus, the ratchet member 154 is a modification of the ratchet member 54 to provide more shift positions. The ratchet member 154 also preferably includes a pair of stops 154d and 154e. Specifically, the stopper 154d is a stationary stopper and the stopper 154e is a completely displaced stopper. The stoppers 154d and 154e are selectively engaged with portions of the holding mechanism 130 so as to control the movement of the winding member 152 and the ratchet member 154. The steering angle of each shift of the ratchet member 154 between the adjacent pair of shift positions is smaller than that of the ratchet member 54. Thus, the manipulation mechanism 128 is a modification of the manipulation mechanism 28 to work with the ratchet member 154, which will be described later.
The biasing member 156 is preferably a torsion spring for applying a urging force to the winding member 152 and the ratchet member 154 to rotate about the main fixing bolt 140. The biasing member (spring) 156 basically includes a first end 156a, a second end 156b, and a coiled portion 156c extending between the first end 156a and the second end 156b. The first end 156a is placed in the spring mounting slot 134c of the bottom plate 134, and the second end 156b is placed in a notch or cutout 152a5 extending from the spring receiving recess 152a4 of the winding member 152. The coiled portion 156c is partially received in the spring receiving recess 152a4. The unit gasket 158 is placed in the center through opening 152a1 of the winding member 152.
The unit pad 158 is preferably a tubular member made of a light rigid material, one end of which is in contact with the lower surface of the bottom plate 134 and the other end is in contact with the upper surface of the middle plate 136 to separate the middle plate 136 from the bottom plate 134. The spring 156 is adapted to bias the winding member 152 in a clockwise direction when viewed from above in FIG. 5 under normal circumstances. In this way, the operating mechanism 128 moves the winding member 152 in the counterclockwise direction by the ratchet member 154 against the urging force of the main biasing member 156. More specifically, the manipulation mechanism 128 preferably moves the winding member 152 to one of the nine predetermined shift positions, which will be discussed later. The holding mechanism 130 selectively holds the winding member 152 and the ratchet member 154 in one of the nine shift positions, which will also be discussed later.
5 and 49-61, the steering mechanism 128 will now be discussed in more detail. The manipulation mechanism 128 is a modification of the manipulation mechanism 28 so that the ratchet member 54 has a larger number of shift positions, which will be described below. The manipulation mechanism 128 basically includes a first manipulation member 160, a second manipulation member 162, a manipulation link 164, and a follow-up link 166. The first operating member 160 forms a four-link mechanism that controls the movement of the first operating member 160 together with the operating link 164, the follower link 166, and the mounting assembly 124. More specifically, the first manipulation member 160 is pivotably coupled to the manipulation link 164 and the follower link 166 for movement along the first arc 1A1, as best seen in FIGS. 63 and 64. The operating link 164 is pivotally coupled to the pivot pin 148 (second fixed pivot) and operatively coupled with the main fixing bolt 140, and the follower link 166 is pivotally coupled to the auxiliary fixing bolt 142 (Fixed pivot). The curvature of the first arc 1A1 is relatively gentle so that the first manipulation member 160 can move along a substantially straight line.
The control link 164 preferably has a pawl mechanism 168 operatively coupled thereto. The pawl mechanism 168 is adapted to engage the manipulation surface 154b of the ratchet member 154 when the first manipulation member 160 is pushed or moved by the rider from the normal rest position to the shift position. In this way, when the first manipulation member 160 moves along the arc 1A1 in a substantially straight direction, the manipulation link 164 also moves so that the pawl mechanism 168 overcomes the urging force of the biasing member 156 and rotates the ratchet member 154 to a shift position . In this way, the winding member 152 is also rotated to pull the inner wire of the shift cable 23 and shift the rear derailleur 17 to one of its shift positions.
When the first manipulation member 160 is moved back to the normal rest position, the pawl mechanism 168 is engaged with the release surface 136a5 of the intermediate plate 136 to disengage the pawl mechanism from the ratchet member 154. However, the holding mechanism 130 is engaged with the ratchet member 154 to hold the winding member 152 and the ratchet member 154 in the new shift position against the urging force of the spring 156. In the illustrated embodiment, the movement of the first manipulation member 160 causes the winding member 152 to be shifted only once from one shift position in one rotation direction to the next adjacent shift position.
The second manipulation member 162 is operatively coupled with the holding mechanism 130 to selectively release the ratchet member 154 and the winding member 152. In other words, the rider pushes or moves the second manipulation member 162 to disengage the holding mechanism 130 from the ratchet member 154, and this causes the winding member 152 and the ratchet member 154 to be urged by the spring 156 Spin. The holding mechanism 130 is adapted so that the winding member 152 and the ratchet member 154 can only rotate through one shift position when the second manipulation member 162 is pushed once. In other words, the ratchet member 154 is engaged with the holding mechanism 130 after rotating through a shift position. Thus, in the illustrated embodiment, the movement of the second manipulation member 162 causes the winding member 152 to shift from only one shift position in the other rotation direction opposite to the rotation direction generated when the first manipulation member 160 moves. Once to the next adjacent shift position.
As best seen in FIGS. 5 and 49, the first manipulation member 160 is a thin flat member. The first manipulation member 160 is preferably composed of a light rigid material such as a deformed metal thin plate. The first manipulation member 160 basically has an actuating portion 160a and a link portion 160b. The link portion 160b is preferably perpendicular to the actuation portion 160a. The link portion 160b includes a pair of holes 160b1 and 160b2, which are adapted to receive the upper ends of a pair of pivot pins 169 and 170, respectively. The pivot pin 169 is pivotally coupled to the manipulation link 164, and the pivot pin 170 is pivotally coupled to the follower link 166 to move the first manipulation member 160 along the first arc 1A1. The actuation portion 160a may have a button 173 coupled thereto, as shown in FIG. 3, and be actuated or pushed by the thumb or other fingers of the cyclist.
The second manipulation member 162 is preferably a thin flat member composed of a light rigid material such as a deformed metal sheet. The second manipulation member 162 is slidably and pivotably mounted on the auxiliary fixing bolt 142. More specifically, the second manipulation member 162 is slidably and pivotably mounted on the pad 163, and the pad 163 is mounted on the second fixing bolt between the second manipulation member 162 and the follower link 166 142 on. The second manipulation member 162 basically includes a long opening 162a, an actuating flange 162b, and a release flange 162c. An upper end of the pad 163 is housed in the long opening 162a. The release flange 162c is received in the guide opening 136a4 of the middle plate 136 so as to control the movement of the second manipulation member 162 together with the fixed pad 163.
The second manipulation member 162 is actuated by a toggle lever 171 that is pivotably coupled to the mounting flanges 136c1 and 136c2 of the intermediate plate 136. More specifically, the toggle lever 171 is operatively coupled with the actuating flange 162 b so that when the rider pushes the toggle lever 171 with a thumb or other finger, the second manipulation member 162 follows the second manipulation member 62 It moves in a substantially straight direction along a second arc (not shown) in substantially the same manner. More specifically, the release flange 162c is accommodated in the guide opening 136a4 of the middle plate 136, and the upper end of the gasket 163 is accommodated in the long opening 162a so that the actuating flange 162b moves along the second arc.
The second arc is substantially parallel to the arc 1A1, and both arcs preferably have a large radius of curvature so as to enable a substantially straight parallel movement between the first and second manipulation members 160 and 162. In other words, the arcs 1A1 and the second arcs are basically mirror images of the arcs A1 and A2 of the shift control device 20. The return biasing member or spring 172 is operatively coupled between the second manipulation member 162 and the intermediate plate 136. In this way, when the rider releases the toggle lever 171, the second manipulation member 162 and the toggle lever 171 are reset to the normal rest position. The guide opening 136a4 and the release flange 162c of the intermediate plate 136 are adapted to selectively engage / actuate the holding mechanism 130, which will be discussed below.
The control link 164 is preferably a thin flat stepped member composed of a light rigid material such as a deformed metal sheet. More specifically, the manipulation link 164 basically includes a manipulation portion 164a and a coupling portion 164b. As described above, the operating link 164 is pivotably coupled to the pivot pin 148 and operatively coupled to the main fixing bolt 140, and is also pivotally coupled to the pivot pin 169, and the pivot pin 169 Pivotably coupled to the first manipulation member 160. The operating portion 164a basically includes a main hole 164a1, a pawl mounting hole 164a2, a protruding portion 164a3, and an auxiliary hole 164a4. The control link 164 is a modification of the control link 64, and its movement is different from that of the control link 64, which will be described below.
The gasket 165 is mounted on the main fixing bolt 140 and fixed. The pad 165 has a stepped outer surface, and a bottom end thereof is mounted in the main hole 164 a1 of the control link 164. The shape of the main hole 164 a1 is a long circumferential guide opening larger than the lower end of the gasket 165. In this way, the control link can move in a lateral arc with respect to the main fixing bolt 140. Specifically, since the long circumferential guide opening 164 a1 has such a configuration, the lower end of the pad 165 slides relative to the manipulation portion 164 a. The upper end of the gasket 165 is in contact with the middle plate 136 and surrounds the main hole 136 a1 of the middle plate 136. In this way, the manipulation portion 164a of the manipulation link 164 is separated from the intermediate plate 136 by a certain distance.
The pivot pin 148 is fixed between the intermediate plate 136 and the lever holding plate 138. Moreover, the pivot pin 148 extends through the auxiliary hole 164 a4 so that the manipulation link 164 can pivot about the pivot pin 148 instead of the main fixing bolt 140. Thus, the movement of the control link 164 is different from that of the control link 64. More specifically, the auxiliary hole 164 a4 is closer to the pawl mounting hole 164 a2 than the main hole 164 a1, so that the manipulation angle of the movement of the pawl mechanism 168 is smaller than that of the pawl mechanism 68. In other words, the operating link 164 and the pawl mechanism 168 are adapted to work with the ratchet member 154, and the operating angle of the ratchet member 154 between different shift positions is smaller so that the stroke of the first operating member 160 and the forward shift The strokes of the first operating member 60 of the gear operating device 20 are substantially the same.
The pawl mechanism 168 is coupled to the pawl mounting hole 164a2, and basically includes a pawl pivot pin 174, a pawl spring 176, and a pawl member 178. The lower end of the pawl pivot pin 174 is mounted in a pawl mounting hole 164 a2 of the operation link 164. The pawl member 178 is mounted on the upper end of the pawl pivot pin 174, and the pawl spring 176 normally biases the pawl member 178 relative to the operating link 164. Specifically, the pawl spring 176 has an upper end 176a coupled to the pawl member 178, a lower end 176b received in a spring mounting hole 64a5 of the operating link 164, and a pivot pin 174 surrounding the pawl Coiled portion 176c. The protrusion 164 a3 of the manipulation link 164 functions as a stop member or a motion control member of the manipulation link 164. More specifically, the protrusion 164 a3 is adapted so that portions of the steering link 164 do not interfere with the movement of other components of the rear shift operating device 22 and / or control the movement of the steering link 164.
The pawl member 178 basically includes a mounting portion 178a and a pawl portion 178b. The mounting portion 178a is thinner than the pawl portion 178b and is received on the pawl pivot pin 174. The pawl portion 178b is adapted to contact the manipulation surface 154b of the ratchet member 154 as selected. Specifically, when the manipulation link 164 is driven by the first manipulation member 160, the pawl portion 178b engages one of the grooves 154b1 of the manipulation surface 154b to rotate the ratchet member 154 and the winding member 152 about the main fixing bolt 140 . However, when the first manipulation member 160 and the manipulation link 164 are in the normal rest position, the pawl portion 178b is in contact with the outer release surface 136a5 of the intermediate plate 136.
In other words, the shape of the outer release surface 136a5 is adapted to keep the pawl portion 178b out of engagement with the groove 154b1 of the manipulation surface 154b when the manipulation link 164 and the first manipulation member 160 are in their normal rest positions. In this way, if the second manipulation member 162 is actuated by the toggle lever 171, for example, if the holding mechanism 130 is released as described below, the ratchet member 154 and the winding member 152 are rotated by the urging force of the main biasing member 156 .
The coupling portion 164b of the manipulation link 164 is offset from the manipulation portion 164a, and basically includes a coupling hole 164b1. The coupling hole 164b1 is adapted to receive a lower end of a pivot pin 169 pivotably coupled to the first manipulation member 160.
5 and 53-55 again, the follower link 166 basically includes a manipulation portion 166a, a coupling portion 166b, and a protrusion 166c. The follower link 166 is preferably a step-shaped thin flat member composed of a light rigid material such as a deformed metal sheet. The manipulation portion 166 a is pivotably coupled to the pivot pin 170, and the pivot pin 170 is pivotally coupled to the first manipulation member 160. The coupling portion 166b is pivotably coupled to the auxiliary fixing bolt 142 through a gasket 163. The manipulation portion 166a is offset from the coupling portion 166b. The protruding portion 166c extends upward from the coupling portion 166b, and is adapted to receive one end of a return biasing member (spring) 179.
More specifically, the manipulation portion 166a includes a hole 166a1 adapted to rotatably receive the lower end of the pivot pin 170, and the coupling portion 166b includes a hole 166b1 adapted to receive the lower end of the pad 163. One end of the resetting biasing member 179 is coupled to the protruding portion 166c, and the other end is coupled to the intermediate plate 136 so as to push the follower link 166 to a rest position under normal circumstances. In this way, under normal circumstances, the first operating member 160 and the first operating link 164 are also biased to the rest position under the action of the reset biasing member (spring) 179, because these members constitute three links of the four-link mechanism assembly. Pole.
5 and 62, the holding mechanism 130 will now be discussed in more detail. The holding mechanism 130 basically includes a holding pivot pin 180, a holding biasing member 182, and a locking member 184. The holding pivot pin 180 is coupled to the bottom plate 134 and the middle plate 136. The lock member 184 is rotatably mounted on the holding pivot pin 180. The holding biasing member 182 biases the locking member 184 to a predetermined position under normal circumstances. The structural configuration of the locking member 184 is adapted to engage with the positioning surface 154c of the ratchet member 154. Moreover, the structural configuration of the locking member 184 is also adapted to be engaged with the release flange 162c of the second manipulation member 162 as selected.
More specifically, the upper end of the holding pivot pin 180 is received in the mounting hole 134 b of the bottom plate 134, and the lower end is received in the positioning hole 136 a 3 of the middle plate 136. Thus, the holding pivot pin 180 and the bottom plate 134 cannot be moved relative to the main mounting portion 132. The locking member 184 is placed on the lower end of the holding pivot pin 180 adjacent to the guide opening 136 a 4 of the intermediate plate 136. The upper end of the biasing member 182 is engaged with the protruding section 134d of the bottom plate 134, and the lower end is engaged with the locking member 184 so as to bias the locking member 184 toward a predetermined direction under normal circumstances.
The locking member 184 basically includes a first stopper portion 184a, a second stopper portion 184b, a center hole 184c, a spring-receiving recess 184d, and an actuation protrusion 184e. The lower end of the holding pivot pin 180 is accommodated in the hole 184c so as to place the locking member 184 between the bottom plate 134 and the middle plate 136. The first and second stop portions 184a and 184b are disposed on opposite sides of the teeth 154c1 of the ratchet member 154. The spring receiving recess 184d is adapted to receive the lower end of the biasing member 182. The actuation protrusion 184e is located adjacent to the release flange 162c of the second manipulation member 162 housed in the guide opening 136a4.
When the second manipulation member 162 is actuated by the toggle lever 171, the release flange 162c is engaged with the actuation protrusion 184e so that the lock member 184 is rotated against the biasing force of the spring 182. This disengages the first stopper portion 184a from the positioning surface 154c. Thus, the ratchet member 154 and the winding member 152 are rotated to a shift position by the biasing force of the main biasing member or the spring 156. When the toggle lever 171 is released, the lock member 184 rotates under the biasing force of the spring 182 to engage the next tooth of the positioning surface 154c so as to maintain the ratchet member 154 and the winding member 152 in the desired shift position .
The operation of the rear-shift operating device 22 will now be discussed in more detail with reference to FIGS. 5 and 63-68. When the cyclist wishes to shift the rear derailleur 17 and the chain C from the smaller rear sprocket RS to the larger rear sprocket RS, the cyclist pushes the first manipulation member 160 with a thumb or other finger. The first manipulation member 160 moves to the shift position along the arc 1A1. This movement of the first manipulation member 160 causes the manipulation link 164 and the follower link 166 to rotate about the pivot pin 148 and the auxiliary fixing bolt 42 respectively. When the manipulation link 164 rotates about the pivot pin 148, the pawl mechanism 168 moves with the manipulation link 164. In addition, the long main hole 164a1 slides along the gasket 165.
When the pawl mechanism 168 moves, the pawl member 178 is disengaged from the release surface 136a5 of the intermediate plate 136. The pawl member 178 is then engaged with the ratchet member 154 to rotate the ratchet member 154 and the winding member 152 by one shift position. When the ratchet member is moved from one shift position to an adjacent next shift position by the pawl mechanism 168, the lock member 184 is disengaged from its corresponding tooth 154c1 and is engaged with the next corresponding tooth 154c1. Specifically, when the ratchet member 154 is moved between the two shift positions, the lock member 184 is disengaged from the teeth 154c1 and then re-engaged to hold the ratchet member 154 in the next shift position.
When the rider releases the first manipulation member 160, the first manipulation member 160 moves back to its normal rest position along the first arc 1A1. This movement of the first manipulation member 160 causes the manipulation link 164 and the follower link 166 to rotate about the pivot pin 148 and the auxiliary fixing bolt 142, respectively. The steering link 164 and the follower link 166 rotate until they return to their normal rest positions. The pawl mechanism 178 moves with the manipulation link 164. Thus, the pawl member 178 is moved back to the position engaged with the release surface 136a5 so that the pawl member 178 is disengaged from the manipulation surface 154b of the ratchet member 154. However, the ratchet member 154 is held in its shift position by the lock member 184. If the cyclist wants to shift from the smaller rear sprocket RS to the larger rear sprocket RS again, he pushes the first operating member 160 along the first arc 1A1 again and repeats the above process.
If the cyclist wants to shift the rear derailleur 17 and the chain C from the larger rear sprocket RS to the smaller rear sprocket RS, the cyclist pushes the toggle lever 171 with his thumb or other fingers. When the toggle lever 171 is actuated by the rider, the second operating member 162 moves from the normal rest position to the shift position along the second arc. Specifically, the movement of the second manipulation member 162 is controlled by the guide opening 136 a 4 of the middle plate and the pad 163 coupled to the auxiliary fixing bolt 142. When the second manipulation member 162 is moved to the shift position, the release flange 162c is engaged with the lock member 184. The lock member 184 rotates against the biasing force of the spring 182 to disengage from the teeth 154c1 of the ratchet member 154. The ratchet member 154 can then rotate under the biasing force of the main biasing member or the spring 156.
The locking member 184 will then engage the next adjacent tooth 154c1 when the second manipulation member 162 is released. Specifically, when the rider pushes the shift lever 171, the lock member 184 is disengaged from the tooth 154c1. However, when the rider subsequently releases the toggle lever 171, the second operating member 162 will return to its normal rest position under the biasing force of the return spring 172. In this way, the release flange 162c will release the lock member 184. In other words, the second manipulation member 162 is designed as a structure that can be relatively quickly dialed and released by a cyclist. Then, the lock member 184 is non-rotatably engaged with the next adjacent tooth 154c1 of the ratchet member 154 to complete the displacement from the larger rear sprocket RS to the smaller rear sprocket RS. This process can be repeated if a cyclist is required.
Of course, if the chain C is already on the smallest rear sprocket RS, the stopper located between the lock member 184 and the ratchet member 154 will prevent disengagement from the tooth 154c1. Therefore, if the rider pushes the shift lever 171 while the rear derailleur 17 is located below the smallest rear sprocket RS, the shift will not be performed. Similarly, if the rear derailleur 17 is at its highest position and the chain C is placed on the largest rear sprocket RS, the first operating member 160 will not be able to shift gears due to the stopper between the lock member 184 and the ratchet member 154. . This way, there is no shifting in this case.
