Description

[Detailed Description of the Invention] [Industrial field of application] The present invention attaches an attached body to an attachment body that is a base of attachment as in the case of attaching a radiator grill of an automobile to a body portion in front of a radiator. The present invention relates to a locking clip that can be conveniently used in such a case.

[Prior Art] Plastic parts such as radiator grills are often fixed by plastic clips. Generally, it is usual to attach parts to the body, and to attach the parts through the body, and to insert the clip from the surface side through the mounting hole, and use the brim or locking claw provided on the clip to fix the parts. In the case where the parts are exposed to the outside, for example, in the case of the parts such as the radiator grill described above, it is not preferable to expose the head or the collar of the clip on the surface.

Also, some parts may be permanently fixed, but in many cases it is necessary to remove the lock for maintenance and inspection or for replacement of parts, and therefore the locked state can be released. Is required.

Under such a request, the applicant previously proposed a plastic clip satisfying the two demands with Japanese Utility Model Laid-Open No. 63-119916.

This clip has a first engaging portion having first engaging claws at both ends, and a second engaging portion having second engaging claws, and further includes a clip from the first engaging claw. The lever (arm) is extended through the hollow part that penetrates the center of the main body of the car. For example, when mounting a car radiator grill to the body, for example The first engaging portion is inserted and the first engaging claw is hooked, while the second engaging portion is inserted into the attaching hole provided in the radiator grille which is the attached body, and the second engaging claw is As a result, they are hooked and, as a result, they are fixed so as to connect them. When the radiator grill is disengaged, the clip operates the lever facing the second engaging portion projecting from the front side of the radiator grill through the mounting hole to engage with the mounting hole of the body. The claws are disengaged, which allows the clip to be removed from the radiator grille.

In this way, the above-mentioned clip has a structure in which the engagement of the locking claw that locks the mounting body can be disengaged from the outside when it is difficult to operate directly from the outside because it is between the mounting body and the mounted body at the time of fastening. Therefore, the above requirements can be sufficiently satisfied. However, when it is necessary to use a plurality of clips with a large component such as the radiator grill in the above description to fix the plurality of locations, it is necessary to attach the clips individually. It is not possible to remove the parts simply by releasing the stop, and all clips must be released from the locked state.

[Problems to be Solved by the Invention] The present invention has been devised for the purpose of improving it in view of the above-mentioned problems in actual work.

That is, when the above-mentioned conventional clip is used by one or a few, even one worker can remove the parts, but when it is fixed by a larger number of clips,
Even if the first and second clips can be disengaged from each other, the other clips cannot be disengaged from each other. In this case, a plurality of workers perform the operations separately.

The present invention has been improved and devised in view of such a situation, and its main purpose is to disengage the engagement of the locking claw by operating the lever, and if necessary, engage the lever with the locking claw. It can be restrained in the release posture so that it can not be locked, and even when using multiple clips to lock it, each worker can easily attach and detach parts by restraining each clip in the release posture It is intended to provide a locking clip of the above type.

[Means for Solving the Problems] Based on the above-mentioned object, the present invention has a first engaging portion having a first locking claw at one end and a second locking claw at the other end. Second
Engagement of the first locking claw by swinging a locking release lever extending from the first locking claw toward the second locking part. In the locking clip configured to be released on the side of the second engaging portion, the second engaging portion is provided with lever engaging means for holding the lever in the released state, and the lever engaging means is provided. (EN) Provided is a locking clip which can be disengaged by locking a lever which has been released and released so as to be disengageable.

More specifically, the lever extending from the first engaging claw provided in the first engaging portion through the hollow portion that penetrates the clip main body in the longitudinal direction is guided to the second engaging portion, and the second engaging portion is guided. In the configuration of the clip, which allows the lever to be operated on the attachment side so that the first locking claw can be disengaged,
A protrusion for lever locking, which is a lever locking means, is raised on the inner side surface of the hollow portion of the second engaging portion, and the lever that is rocked to release the first locking claw is locked to the protrusion. Another object of the present invention is to provide a locking clip characterized in that the first locking claw is restrained in the released state.

The hollow part of the second engaging part which allows the extension of the lever allows the free end of the engaging part and two faces in the direction in which the lever is swung to allow a free swinging operation, and both side face parts face each other. Protrusions for locking the lever may be provided on either or both of the inner surfaces. Of course, the lever bent by the releasing operation can be engaged by passing over the protrusion to be held in the releasing posture, and can be engaged with the first locking claw by returning to the original state by passing over the protrusion again. It can be returned to the state and used for fastening.

The protrusion 14 is provided so as to face the lower end portion of the side surface portion 8 facing the opening 7, and is located below the free end of the lever 11 extending along the upper open portion of the side surface portion 8 8. There is.

The locking clip of the present invention is constructed as described above,
Next, the actual use of this clip will be explained based on the mounting of the radiator grill of the automobile.

The body A of the car, which is the mounting body prior to use, has the first
A radiator grill B, which is also a body to be mounted, is provided with a mounting hole a having a uniform cross-sectional shape that enables insertion of the engaging portion 4 of
A mounting hole b into which the second engaging body 5 is inserted is provided on the side. These mounting holes a and b are formed facing each other at corresponding positions, and a plurality of mounting holes are provided depending on the shape, size, etc. of the body to be mounted.

The procedure for attaching the clips is not specified to one in accordance with the actual work, but when using a plurality of clips, that is, in the case of a radiator grill, first from the rear side of the radiator grill to the attachment hole b provided in this. The second engaging portion 5 mainly composed of the clip is faced and pushed in, and the second engaging claw 9 provided therein is hooked on the edge of the attaching hole b to attach it.

Clips are attached to a plurality of mounting holes b, and they are mounted so as to project to the rear side. This radiator grill B
To the front surface of the body A, so that the first engaging portions 4 of the respective locking clips face the respective mounting holes a. After that, when the respective locking clips are pressed into the mounting holes a by pressing on the front surface of the radiator grille, the first locking claws 10 are inserted into the edges of the mounting holes a at the same time when the first engaging portions 4 enter. To complete the mounting of the radiator grill.
Incidentally, the collars 2 and 3 which have been given elasticity when the engaging portions are inserted by this pressing are once bent open to allow the engaging portions to enter, and further the engaging claws 9 and 9 and the engaging claws. After allowing 10 engagements, these locking claws are strongly engaged with the edges of the mounting holes by the restoring force.

The two-dot chain line in Fig. 4 shows this figure, and each locking clip to which the radiator grill is attached by the above-mentioned procedure is hidden behind the radiator grill, and only the tip part of the second engaging part 5 and this Lever 11 looking through opening 7
Only the free end of the above is slightly exposed to the outside through the mounting hole b.

In this way, the locking clip with the radiator grill attached to the body is barely visible because the main body is hidden behind the radiator grill. However, as described above, the lever 11 is exposed to the outside through the mounting hole b. By swinging the lever 11, the first locking claw 10 engaged with the mounting hole a of the body can be disengaged, and the clip can be attached to the radiator grille. Can be removed from the body. At this time, the locking clip of the present invention is provided with the protrusion 14 on the second engaging portion 5 from which the lever 11 extends, so that the free end of the lever 11 bent to release the engagement of the locking claw 10 is protruded. Since the locking claw 10 can be held in the releasing posture by locking the lever 11, the worker does not have to hold the lever 11 in the releasing direction in the removal work.

FIG. 7 shows the first end of the lever 11 when the free end of the lever 11 is locked to the protrusion 14.
The lock claw 10 is disengaged, and the lever is locked by forcibly pushing it down between the opposing projections 14 and using the elasticity of the material to climb over the projection. .

In the illustrated embodiment, the projections 14 are formed on the side surface portions 8 and 8 so as to face each other, but one of them may be omitted. Also the locking claw 10
The lever 11 extending from the first engaging portion is formed to have substantially the same length along the upper surface opening portion of the second engaging portion, but this length is for facilitating the swinging operation. There is no particular obstacle. It should be noted that the swinging operation of the lever may be performed by using a suitable rod-shaped tool such as the tip of a driver, and therefore even if the free end of the lever is inside the hollow portion 6, there is no operational problem.

By the way, for convenience of explanation, the first engaging portion 4 is mounted in the mounting hole a provided in the body A with the body as the mounting body and the radiator grill as the mounted body, and the radiator grill mounting hole b.
The case where the second engaging portion 5 is attached has been described above.
Of course, the respective insertions may be reversed so that the first engaging portion 4 is attached to the radiator grill side and the second engaging portion 5 is attached to the body side.

In the case of a radiator grill, reversing this mounting is to avoid opening a mounting hole in the front, and in this case, install a mounting hole in the rear part of the radiator grill in an appropriate place to prevent it from being exposed, but on the body side Because of the facing second engaging portion 5, a mounting hole into which the second engaging portion 5 is inserted is provided on the rear surface of the body at a portion where a proper working space can be secured so that the lever 11 can be operated using this working space. Will be done.

[Effects of the Invention] The embodiments of the present invention have been described in detail above. The locking clip of the present invention is used to mount an object to be mounted face-to-face such as a radiator grill to a mounting body such as an automobile body. In this case, the entire clip can be concealed between these two parts, and the locked state can be released by disengaging one of them by operating the lever, which is advantageous as a means for mounting parts. At the same time, since it is possible to engage a locking release lever that releases the engagement of the locking claws in the release of the attachment with the locking means and hold it in the release posture, Even when parts are attached using multiple clips, it is not necessary for each worker to individually hold the lever of each clip in the release position, and therefore one worker can fasten with multiple clips. The attached body can be easily removed. Of course, the locking clip of the present invention can be reused because the first locking claw can be restored to the original shape by locking the lever from the projection locked in the release position.
If the attachment clip is attached to the attached body and the attached body is pressed toward the attached body, the attached state is automatically obtained.
