Door holder

[Detailed Description of the Invention]

This invention relates to the check strap assembly object of integral moulding which can be used when restricting the migration length between two moving parts in detail than a stop device. In a design and assembly procedure of various machinery elements, in order to hold two moving parts in a predetermined distance, it is often necessary to form a stop device. Since it is not desirably allowed again in the case of the door with a hinge which should be held in the specific direction that a door opens too much greatly when it opens completely, that is especially right. When the door of the glove box seen in the backboard of a station wagon or the field of the auto industry opens completely in the example of representation, it is desirable to hold a door at a level posture. In order to satisfy the above-mentioned demand, various kinds of devices are used and it can approve once until now, and it is Oh. However, as for a conventional method and structure, the necessity of using a screw, a rivet, and other fixing devices for generally fixing a stop device to a structure is Oh. Assembly art required generally, in order to attach these devices needed the considerable labor also for needing many parts attached at an expensive price, in order to maintain stock, and attaching various kinds of given parts. In the case of the door of the glove box of a car, it is a usual state for repair and service to take time and to do damage to related component part through the lifetime of a car, since [ being considerable ] number-of-times opening and closing must be carried out and it is necessary to remove a stop device each time, and it is Oh. When the example which uses one strap for stopping the door of a glove box is taken, the number of the minimum independent parts which should be kept with stock for exchange or supply is three pieces. Namely, a cable is one and the number of fasteners with a screw is two. It is necessary to exchange this fastener with a screw for a bigger fastener in many cases in order to damage a structure, when removing from a structure. Thus, even if it Anger so that the specific number of parts may be maintained at the minimum, many fasteners and cables are needed for installing this kind of stop device. Attachment removal can be performed easily, without the object of this invention not requiring expense, being able to manufacture easily, and damaging an associated part from the above thing, and it is in providing the check strap which can restrict the migration length between two moving parts. The another object of this invention is to provide the product which comprises the check strap assembly object by forming processing which can be connected so that it may push in by forming processing and may be united in a pin, and can be kept as a product of a simple substance to the first attachment, exchange, or supply. Other objects which will become clear as the above-mentioned object and the following explanation progress, A pair of bosses connected by the elastic body link are comprised, and but the circular inner diameter part to penetrate is formed in each of a boss and the comparatively thin wall is made, it is attained by providing the strap of a simple form. The portion inclined so that an inner diameter dimension might become the minimum near the end of each boss's circular inner diameter part is Okay. stretch ing to a boss's end. In the state where the boss has been stationed in the hole of a structure, the pushing pin which has a cylindrical axis part is inserted in a boss's inner diameter part. A boss seems to be able to extend the hole by the side of a structure with the minimum inner diameter dimension, when a pushing pin is inserted in a boss. The flange is provided in the boss's end at which a pushing pin is inserted, and when it is completely inserted into a boss's inner diameter part, the head with the surface which faces a flange is attached to the pushing pin. Since the slot which can insert a tool is made when camfering makes it a pushing pin and the both sides of the surface of a flange and Then and both sides are piled up, a pin can be wrenched open and can be easily removed from a boss. Intermediary To have [ as ] which holds a strap in a predetermined position when a strap is inserted in a structure when it has the parallel long and slender member prolonged from the strap portion near the boss and a boss is inserted, a boss's rotation is prevented and a strap is attached to a structure by this. In a desirable example, it pushes in with a strap and a pin is fabricated as a single structure, and in it, each of the pushing pin is connected so that it may be united to each boss by the portion which a strap tends to fracture. The example for explanation of an invention is shown in the accompanying drawing. The new feature and advantage of an invention will be clarified by the following explanation. Drawing 1 and Drawing 2 are explained first. Strap assembly object 10 of integral moulding of illustration is arranged to the both ends, and has elastic body link 12 which goes mutually and has bosses 14 and 16 of one pair of Be consistent. Each above-mentioned boss 14 and 16 has circular flanges 18 and 20 which have projected outward from the end of the boss with whom link 12 is connected. Circular inner diameter parts 22 and 24 to penetrate are prepared for each boss 14 and 16, respectively. the size that each boss gets a comparatively thin wall as for bosses' 14 and 16 outside diameter, and the diameter of inner diameter parts 22 and 24 -- intermediary To have. the end of bosses 14 and 16 who have inner diameter parts 22 and 24 in the side opposite to each flange -- by the way -- the full length of an inner diameter part -- it inclines inside from a half to the open end mostly. A plurality of slots 25 are prolonged to the part where a Almost along inclination begins from the inclined end of inner diameter parts 22 and 24 in the longitudinal direction of an inner diameter part. Each boss 14 and 16 was adjoined and the long and slender member is prolonged in the form of cylindrical pins 26 and 28 of a diameter quite more long and slender than a boss from the part where each flange 18 and 20 is connected with link 12. It pushes into the both ends of flanges 18 and 20, respectively, pins 30 and 32 are fabricated, and each is connected with the flange with tab 33 which is easy to fracture. Each pushing pin 30 and 32 is Be formed from cylindrical heads 34 and 36 and cylindrical axis parts 38 and 40. What should be observed especially in Drawing 2 is that push in, and field 41 cuted off the corners is established below pin 20, and same field 42 cuted off the corners is established in the edge of flange 18. The object will be clarified as explanation progresses. About each feature explained above, it can be judged as that in which the field same since the structure of boss 14 and boss 16 is the same like pushing pins 30 and 32 also as flange 20 of pushing pin 32 and boss 16 cuted off the corners is established. In the case of the example of illustration, strap assembly object 10 is made from nylon materials by injection molding, but it is other suitable charges of an elastic material, and may use what has possible carrying out injection molding. About the typical size of the structure shown in the desirable example, Bosses' 14 and 16 outside diameter is 0.310 inch (7.9 mm), the main inside diameter is 0.268 inch (6.8 mm), and the inside diameter inclines at an angle of 15 * from a 0.160 inch (4.0 mm) part to [ from a boss's end face ] the minimum diameter. The diameter of the axial part of each pushing pin 30 and 32 is 0.268 inch (6.8 mm). Next, Drawing 3 and Drawing 4 are explained. In order that strap assembly object 10 may hold door 50 of a glove box with a hinge by fixed physical relationship to structure 52 of a glove box, when being used, it explains per. Probably, it will be clear that perform [ how to attach the opposite end of the assembly object over structure 52 / similarly ] I want you to be careful here, although how to attach strap assembly object 10 over door 50 and structure 52 explains only the assembly object end of the direction fixed to a door. When Drawing 3 is explained in detail, it is as preparation by the side of the glove box door for attachment of strap assembly object 10, One pair of only bigger holes 54 and 55 of the diameter than those outside diameters for inserting cylindrical pin 26 into the box-frame construction of a door with boss 14 are punched on the center line corresponding to the above-mentioned boss and a pin. Next, in order to insert in boss's 14 inner diameter part 22, pushing pin 30 is separated from strap assembly object 10. It is possible to fabricate tab 33 in the size which can separate both only by only twisting pushing pin 30 and assembly object 10, and making it pull them apart simultaneously using known injection molding technique. Next, boss 14 and pin 26 are inserted in holes 54 and 54, respectively, and structure of an assembly form as pin 30 stuffed into a boss and shown in Drawing 3 is made. If axial part 38 is pressed fit in inner diameter part 22, be careful to boss's 14 outer wall being extended and it becoming impossible to remove a boss from the box-frame construction of door 50. that slot 25 of plurality [ this ] is provided, and inner diameter part 22 -- point Fine -- for an intermediary To have reason, it is because a boss's end can project to the outside of hole 54. Link 12 is prevented from being inserted between a door and a structure, when the door of a glove box is in Open position, it is made for the center line of holes 54 and 55 of door 50 or structure 52 to be located in a line in a straight line and door 50 is closed. Intermediary To have [ as ] which link 12 moves below and enters into a door opening when a door closes since pin 26 or 28 prevents boss 14 or 16 rotation. In the state where pushing pin 30 was completely inserted in boss 14, Drawing 3 shows fields 41 and 42 cuted off the corners pushing in and forming the slot in the circumference of the circumference of head 34 of a pin. Pushing pin 30 can be removed easily, without inserting a screw driver or the Sharp tool of other points between head 34 and flange 18, and damaging all of the parts of an assembly object by this slot. Although this strap assembly object 10 was carried out, it can be used for an intermediary and the structure that needs to perform removal of component parts frequently, It can be re-used any number of times, without spoiling the completeness of a structure (i.e., without it fixes all of the component parts connected by a strap assembly object or it).
