Description

[Detailed description of the invention] This invention relates to a synthetic resin clip used when attaching a molding to a member to be attached such as a car body side or a bumper. The present invention relates to a clip for a molding, which includes a head portion held within an engagement rail with a large space, and a leg portion elastically engaged with a mounting hole of a member to be attached.

As shown in FIG. 1, a conventional clip of this type is made of a synthetic resin material and has a leg portion 4 that can be elastically engaged with a mounting hole of a member to be attached, and a leg portion 4.
The molding 1 to which the clip 3 is attached has a head 5 having a larger internal space than the opening 2a in the longitudinal direction of the rear surface. Go rail 2
When assembling the clip 3, the head 5 is inserted into the engagement rail 2 from the end of the molding 1 cut to a predetermined length, and the leg 4 is inserted into the opening 2a.
The clips 3 are assembled at the predetermined positions on the back surface of the molding 1 by protruding from the molding 1, sliding a predetermined number of clips 3 to predetermined positions, and caulking the engagement rails 2 on both sides of each clip 3.

Therefore, for such a clip 3,
The length of the molding 1 itself is usually about 1200 mm, and the clips 3 need to be assembled at 7 to 8 locations at intervals of 150 to 200 mm, and it is a hassle to insert them one by one from the end of the molding 1 and slide them to the specified position. In addition, if the end of the molding 1 is not cut cleanly and has burrs, it will be difficult to insert the clip 3. Furthermore, when assembling the clip 3, be careful not to touch the engaging rails 2 near both sides of the clip 3. Since it is necessary to tighten the clip 3 to prevent it from slipping, the surface of the molding 1 sometimes becomes deformed.

This idea solves the above problems,
The head is inserted into the predetermined position of the engagement rail opening on the back of the molding and rotated approximately 90 degrees without having to insert it from the end of the molding and sliding it, and without the need for caulking work that deforms the molding. To provide a molding clip that can be easily and directly assembled.

The gist of this invention is that the head is held in an engagement rail formed in the longitudinal direction of the back of the molding and has a larger internal space than the opening, and the legs are elastically engaged with the attachment holes of the attached member. A clip for a molding made of synthetic resin, the head having a shorter diameter smaller than the opening width of the engagement rail and a longer diameter larger than the opening width of the engagement rail that can be stored in the engagement rail, A neck part is formed between the head part and the leg part with a length corresponding to the thickness of the opening part and whose maximum cross-sectional dimension is less than or equal to the engagement rail opening width, and the head part is further inserted through the engagement rail opening part. When rotated approximately 90 degrees in the axial direction, it deforms elastically in response to the engagement rail to prevent rotation, and parallel to the longitudinal direction of the head which holds the periphery of the opening with the head. A clip for a molding is characterized in that a locking piece is formed thereon.

Hereinafter, embodiments of this invention will be described based on illustrated examples.

Figures 2 to 4 show the clip of the first embodiment of this invention, Figure 2 is a perspective view showing how it is used, Figure 3 is a perspective view of the clip, and Figure 4 is a sectional view of how it is used. Figures 5 to 7 show the clip of the second embodiment of this invention. Figure 5 is a perspective view showing how it is used, Figure 6 is a perspective view of the clip, and Figure 7 is a sectional view of how it is used. be.

The clip 13 of the first embodiment is integrally molded from a synthetic resin material with spring elasticity such as nylon or polyacetal, and can be elastically attached to a mounting hole 18a in a mounting member 18 such as a side surface of an automobile body or a bumper. A locking piece 17, a neck part 16, and a head part 15 are formed in order from the leg part 14 in the axial direction.
is formed.

The head 15 of the clip is attached to the engagement rail 12, which has an internal space (internal width W) larger than the opening 12a (opening width h) formed in the longitudinal direction of the back surface of the molding 11.
The short axis (dimension in the short direction) x is smaller than the opening width h of the engagement rail, and the long axis (dimension in the longitudinal direction) y is the internal width W of the engagement rail. It is formed to have a dimension that is equal to or larger than the opening width h, and both ends in the longitudinal direction are formed in an arc shape.

The neck portion 16 of the clip has a length substantially equal to the thickness e of the engagement rail opening 12a, and has a maximum cross-sectional dimension smaller than the engagement rail opening width h.

The locking pieces 17, 17 of the clip are formed parallel to the longitudinal direction of the head 15, and hook-shaped locking portions 17a are formed at both ends, respectively. The distance at which the locking portion 17a is formed is such that when the locking pieces 17, 17 are positioned in the short direction of the engagement rail 12, they can clamp both end surfaces of the engagement rail 12 in the short direction. It's the location.

Therefore, when this clip 13 is assembled to the engagement rail 12 on the back surface of the molding 11, the clip head 15 should be made parallel to the longitudinal direction of the engagement rail 12, and the head 15 and neck 16 should be inserted into the opening 12a. When inserted and the clip 13 is rotated approximately 90 degrees in the axial direction, the locking pieces 17, 17 are elastically deformed, and the locking portions 17a clamp both ends of the engagement rail 12 in the lateral direction. The clip 13 stops rotating, and the head 15 of the clip 13 is connected to the engagement rail 1.
The head 15 and the locking piece 17 sandwich the periphery of the opening 12a and are assembled at a predetermined position on the engagement rail 12.

Then, the clip 1 is assembled in a predetermined position.
By engaging the leg portions 14 of No. 3 into the attachment holes 18a, the molding 11 can be attached to the member to be attached 18.

The clip 23 of the second embodiment has legs 24, a head 25, and a neck 26 formed similarly to the clip 13 of the first embodiment, but the locking piece 27 has an opening 22a in the engagement rail 22. It is formed to correspond to two grooves 22b formed in parallel therebetween.

This locking piece 27 is formed with a notch 27c parallel to the longitudinal direction of the head 25, and a locking portion 27a having a locking protrusion 27b near the tip is formed to be easily bent. The distance between the two locking protrusions 27b, 27b is formed to be the same as the distance between the two grooves 22b on the engagement rail 22.

Therefore, when assembling this clip 23 to the engagement rail 22 on the back surface of the molding 21, the clip head 25 is made parallel to the longitudinal direction of the engagement rail 22, and the head 25 and neck 26 are aligned with the opening 2.
2a and rotate the clip 23 approximately 90 degrees in the axial direction, the locking portion 27a of the locking piece 27 deforms elastically, and the locking protrusion 27b fits into the groove 22b. stop its rotation,
The clip 23 is assembled at a predetermined position on the engagement rail 22 so that the head 25 will not come out from within the engagement rail 22 and the periphery of the opening 22a is held between the head 25 and the locking piece 27.

The attachment to the attached member 28 is the same as in the first embodiment.

Note that in the clip 23 of the second embodiment, when a protrusion is provided in place of the groove 22b provided on the engagement rail 22, a protrusion corresponding to the protrusion is provided in place of the locking protrusion 27b of the locking piece 27. A similar effect can be achieved by providing a recess.

In addition, usually the moldings 11 and 21 are made of synthetic resin,
Although the attached members 18 and 28 are made of metal and have different thermal expansion coefficients, the fixing force in the longitudinal direction of the engagement rails 12 and 22 in the clips 13 and 23 of the first and second embodiments is 15, 25 and locking piece 1
This is a spring elastic clamping force on the peripheral edges of the openings 12a and 22a between the clips 7 and 27, and the clips 13 and 23 can be displaced in the longitudinal direction of the molding to sufficiently cope with deformation caused by thermal expansion. This also means that if there are variations in the positions of the mounting holes 18a, 28a provided at predetermined intervals in the attached members 18, 28, the clips 13, 23 may be shifted within the engagement rails 12, 22 after the clips are assembled. This has the effect of making it compatible.

The molding clip according to this invention has the above-described structure and function, and the head and neck parts are inserted into the engaging rail opening parallel to the engaging rail and rotated approximately 90 degrees around the clip axis direction. For example, the locking piece stops the rotation and the head cannot come out from inside the engagement rail, and the head and the locking piece clamp the opening periphery, so it cannot be inserted from the molding end like a conventional clip. This eliminates the need to slide the clip to a predetermined position, and also eliminates the need for caulking work that deforms the molding, making it possible to simply and easily assemble the clip to a predetermined position on the molding engagement rail.
