Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a striker engagement tool that engages and holds a striker while absorbing impact force from the striker.

Generally, in a vehicle as shown in Fig. 1,
For example, a spare tire carrier C as a movable member is disposed at the rear of the vehicle body B as the main body, and one end of the spare tire carrier C is attached to the vehicle body B in order to enable the opening operation of the back door 1. A hinge 2 is supported on one rear side, and the other end is connected to and detached from the other rear side of the vehicle body B with a locking member 3 (for example, the new Nissan Patrol 60 model car published by Nissan Motor Co., Ltd. in May 1963). Refer to ``Introduction to the System.'' In Fig. 1, 7 is a spare tire.In this case, when fixing the open spare tire carrier C to the vehicle body B, the spare tire carrier C is attached to one side at the hinge 2. Spare tire carrier C
is bent due to its own weight, etc., resulting in a situation where the locking member 3 of the spare tire carrier C cannot be properly engaged with the engaging portion on the vehicle body B side. In order to solve such problems, for example, a part of the frame member that constitutes the spare tire carrier C is made to function as a striker S, while a striker is attached to a part of the vehicle body B that corresponds to this striker S, in this case, the back door 1. It is possible to position the spare tire carrier C at its fixed position while correcting the displacement of the spare tire carrier C by providing an engaging tool K and engaging the striker S with this striker engaging tool K.

In such a case, the conventional striker engaging tool K, for example, as shown in FIG.
It is composed of a holder 4 fixed to the holder 4, and a buffer body 5 made of rubber or soft resin that is fitted and held in the holder 4 and has a recess 6 in which the striker S engages. A guide tapered surface 6a that widens outward is formed at the upper and lower edges of the portion. Therefore, when the striker S enters toward the striker engagement tool K, even if the relative positional relationship between the striker S and the striker engagement tool K is deviated by the dimension d, the striker S
After colliding with the guide tapered surface 6a of the buffer body 5,
The striker S moves along the guide tapered surface 6a.
The striker S engages in the recess 6 while correcting its position, and at this time, the impact force from the striker S is absorbed by the buffer body 5.

However, in such a conventional striker engagement tool, since the buffer body 5 is made of rubber or soft resin, when the striker S tries to enter the recess 6 of the buffer body 5, A relatively large frictional resistance occurs at the contact portion between the metal striker S and the recess 6, and this has the disadvantage that engagement of the striker S into the recess 6 tends to become uncertain. Ta.

The present invention has been made in view of the above, and an object thereof is to provide a striker engaging tool that can smoothly and reliably engage a striker. .

The gist of the present invention is to hold a cushioning body made of rubber or soft resin, which is provided with a recess with which a striker engages, with a fixing holder;
The striker engaging tool is provided with a guide piece having a small coefficient of friction with respect to the striker in a sliding contact portion of the recess of the shock absorber with the striker.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

The striker engaging tool K shown in the embodiment shown in FIGS. 3 and 4 engages with the striker S of the spare tire carrier C, as in the conventional case, and is attached to the vehicle body B side.

In this embodiment, the striker engagement tool K is
It consists of a holder 4, a buffer body 5, and a guide piece 10, and the holder 4 has a rectangular cylindrical holder body 1.
1, with bent mounting flanges 12 for attaching to the vehicle body B on both sides of the base end thereof, and notches 13 provided on both side walls of the holder body 11 from the tip to the base end. It is. Further, the buffer body 5 is integrally formed of rubber or soft resin,
It is fitted and held in the holder body 11 and has a stopper portion 14 at its base end that abuts against the base end of the holder body 11. The shock absorber 5 has a recess 6 that engages with the striker S in the notch 1.
3, a guide tapered surface 6a that expands outward is formed at the entrance portion of this recess 6, and a hook-shaped cross section is formed at the back of the upper and lower inner wall surfaces of this recess 6. A locking groove 15 is formed. Further, the guide piece 10 is integrally molded from a hard resin having a small coefficient of friction against metal, such as polyacetal, and has a predetermined gap 18 left in the length direction of the holder main body 11 at one end thereof, and a distal edge thereof. A hook-shaped locking pawl 16 is formed on the other end, and a locking portion 17 that engages with the locking groove 15 is formed on the other end of the guide piece 1.
0 are arranged along the upper and lower inner wall surfaces of the recess 6, which is the sliding contact portion of the striker S.

The striker engaging tool K made of such structural members is first inserted into the holder main body 11 from the rear of the holder 4.
Then, the locking portion 17 of the guide piece 10 is inserted into the locking groove 15 of the buffer body 5, and the locking claw 16 of the guide piece 10 is connected to the tip edge of the holder body 11. By stopping the parts, it can be assembled without using adhesives or the like.

Therefore, according to the striker engagement tool according to this embodiment, the striker S is attached to the striker engagement tool K.
When the striker S enters, the striker S collides with the guide piece 10 covering the upper and lower inner wall surfaces of the recess 6, and fits into the recess 6 while slidingly contacting the guide piece 10. At this time, since the guide piece 10 has a small coefficient of friction with respect to the striker S,
The frictional resistance generated at the contact portion between the striker S and the guide piece 10 becomes extremely small, and the striker S is guided by the guide piece 10 and smoothly moves into the recess 6 and is securely engaged in the recess 6. . or,
There is a gap 18 between the guide piece 10 and the holder 4.
is provided, so when the striker S collides with the guide piece 10, the buffer body 5 is elastically deformed by the gap 18, and the impact force from the striker S is alleviated by that amount. . Furthermore, when the striker S reaches the innermost part of the recess 6, the striker S will come into direct contact with the buffer body 5, so the elastic deformation of the buffer body 5 will cause the striker S to The impact force is further reduced.

In addition, in the above embodiment, the guide piece 10
is attached to the locking groove 15 of the recess 6 and the tip edge of the holder body 11, but is not necessarily limited to this, and may be fixed to the inner wall surface of the recess 6 using an adhesive or the like. It's okay. Also, holder 4,
The specific shapes of the buffer body 5 and the guide piece 10 may also be modified as appropriate. Further, in the above embodiment, the present invention is applied to the striker engagement tool K for positioning the fixed position of the spare tire carrier C as a movable member, but the present invention is not limited to this. It goes without saying that the present invention can be applied to general striker engaging tools K that are not limited to vehicles, including a striker engaging tool K for positioning the open position and closed position of a vehicle. Furthermore, in the above embodiment, the striker engaging tool K is provided on the main body side such as the vehicle body B, but in the case where the striker S is provided on the vehicle body side, the striker engaging tool K is provided on the movable member side such as the door. All you need to do is provide a fitting.

As explained above, according to the striker engagement tool of the present invention, a rubber or soft resin shock absorber having a recess with which a striker engages is held by a fixing holder, and the shock absorber is held by a fixing holder. Since a guide piece with a small coefficient of friction against the striker is provided in the part of the recess that slides into contact with the striker, the striker is smoothly guided into the recess along the guide piece, and the engagement movement with the striker is accordingly reduced. It will be smooth and reliable.
