Description

[Detailed description of the invention] (Industrial application field) This invention relates to the improvement of clips for attaching decorative items and other parts to painted surfaces, and more specifically relates to moldings, cowl louvers, etc. This invention relates to a further improvement of U.S. Pat.

(Prior art) The clip for protecting paint film according to Utility Application No. 18620/1986 uses a clip-based attachment method instead of the conventional method of attaching decorative items such as adhesion, welding, riveting, or caulking, and a method for attaching the decorative item using the clip. This attempt was made to solve the various inconveniences that occur by using a soft cap in combination.

Clips, which are used as a means of attaching parts such as decorative items, have the advantage that unlike the above-mentioned adhesives, welding, riveting, or caulking, they can be attached easily and reliably without damaging the painted surface. Because it has good mechanical strength for installation and is easy to repair and replace, it has recently been used in various fields, and is especially suitable for installing painted decorative materials. .

However, when using such clips to attach decorative items, etc., the clips themselves are usually made to have sufficient hardness, and the clips are tightly fitted in order to increase the mechanical strength of the clips. Therefore, there is a problem in that the painted surface of the periphery of the clip may be damaged due to vibrations generated when the clip is inserted or in the clip portion that is inserted.

Therefore, by fitting a soft cap onto this clip and interposing this cap between the mounting surface and the clip, it is possible to prevent the rubbing phenomenon of the mounting surface that occurs when the clip is inserted and the vibration of the inserted clip part. Attempts have been made to avoid the accompanying rubbing phenomenon.

In particular, Utility Model Application No. 18620/1986 proposes to improve the cap to be attached to such a clip, and the clip A' and cap as shown in FIG.
We proposed a paint film protection clip consisting of B'.

This paint protection clip uses mounting plate 1.
A pair of claw pieces 102a, 102a are provided on the mounting leg 102 that stands up from 01, and the claw pieces 10
2a, 102a and the plate 101, the clip is configured to hold the mounting surface between
A', and has window holes 110, 110 which are fitted into the mounting leg part 102 of the clip A' and in which the free end side of the claw piece 102a is exposed to the outside;
A rising wall 112 is left between the window hole 110 and the peripheral flange 111, and this rising wall 112 is composed of a cap B' configured to cover the free end of the claw piece 102a of the clip A'.

Therefore, with this paint film protection clip, the mounting surface of the clip does not come into direct contact with the clip A', but rather connects the rising wall 112 and the flange 111 of the cap B'.
Since the clip A' is brought into contact with the clip A' in a separated state, there is no possibility of scratches on the mounting surface that occur when clip A' is fitted, or damage to the mounting surface due to rattling of the attached clip. Ta.

Furthermore, in this paint film protection clip, the free end sides of the claw pieces 102a, 102a for fitting and securing the clip are largely exposed to the outside of the cap B', and as a result, the fitting of the clip A' is difficult. This effectively prevents the cap B' from extending out on the claw piece 102a, which sometimes occurs, and prevents any repulsive stress from remaining on the cap B' of the attached clip, and also provides a sufficient click feeling when the clip is attached. The structure was designed to produce the following.

(Problems to be Solved by the Present Invention) In spite of the above-mentioned features, the clip for protecting paint films according to Utility Application No. 18620/1983 has the following problems:
Attachment of cap B' to A', especially temporary fixing, is difficult, and when fitting the clip to the attachment surface, it is necessary to insert cap B' into clip A' while covering it one by one. In order to improve the fit of the clip into the mounting hole on the mounting surface, the legs of the clip A' are shaped to taper toward the top, and the cap B' itself, which is fitted onto this leg, is also shaped to become narrower towards the top. Same shape, only 1 nail piece
A rising wall 112 of cap B' is attached to the free end of 02a.
This is due to the fact that the cap B' and the clip A' were temporarily fixed only by engaging the cap B' and the clip A'.

In addition, in the paint film protection clip according to Utility Model Application No. 18620/1980, the clip that is fitted into the fitting hole on the mounting surface has claw pieces 102a, 102a on its legs.
Those with a slight play width on the side.
Since the structure basically has no play width on the side where the claw piece 102a is not provided, there is an inconvenience that dimensional errors during installation cannot be absorbed by the clip.

(Purpose and Structure of the Present Invention) The paint film protection clip according to the present invention is intended to be a further improvement of the clip shown in Utility Application No. 18620/1983 among such conventional clips, and is particularly While retaining the advantages of the clip shown in Utility Application No. 18620/1986, the clip has been improved by providing the clip with a temporary fixing mechanism for the cap and a mechanism for conforming the clip to the mounting surface, both of which were considered difficult points in the clip. This makes installation easy and reliable, and also effectively absorbs dimensional errors during installation to improve installation accuracy.

The paint film protection clip according to the present invention, as a means of achieving the above purpose, first has an elastically deformable claw on the insertion leg of the clip A that slopes outward from the top of the clip A toward the leg machine side. and engaging claws protruding toward the base of the leg on both sides of the leg so as to sandwich the claw, and a convex provided on the inside of the free end of the claw. The gap between the edge and the outer edge is a jaw, and the entire cap B that is fitted onto the clip A is configured as a cap-shaped body, and the opening edge of the cap B forming the cap-shaped body has an outer edge. A flange is provided toward the cap-shaped body, and the peripheral wall of the cap-shaped body is provided with a window hole through which the free end side of the claw piece of the clip A is exposed, and a slot into which the engaging claw is inserted and exposed;
Furthermore, the peripheral wall between this slot and the lower side of the window hole, that is, the opening edge of the cap B or the flange, is left as a rising peripheral wall, and furthermore, it is designed to cover at least a part of the top of the slot. A bag portion was provided to form a cap B.

Then, by fitting the cap B onto the clip A by sliding the rising circumferential wall of the cap B over the claw pieces and the engaging claws of the clip A, one of the rising circumferential walls is caused to slide over the claw pieces of the clip A and the engaging claw. At least the jaw portion is covered, and the other rising peripheral wall is configured to be engaged with the engaging claw.

(Functions and Effects) The paint film protection cap according to the present invention has the above-mentioned structure, and the cap B fitted into the clip A has the following characteristics:
A part of the rising peripheral wall is engaged with the engaging claw of clip A, and since the bag portion is formed in cap B so as to cover this engaging claw, the engaging claw of clip A is engaged with the engaging claw of clip A. There is no inconvenience of direct collision with the hole edge of the mounting surface, and moreover, there is a feature that play corresponding to the expansion of the bag portion is provided between the clip A and the hole edge of the mounting surface.

Therefore, after fitting the cap B onto the clip A and temporarily fixing the clip A and the cap B,
By inserting the cap B into the hole edge of the mounting surface and inserting the clip A while aligning the center, the clip A is pushed into the hole of the mounting surface while being guided by the cap B.

When the clip A is pushed in, the claws of the clip A are gradually inserted while being pressed against the edge of the hole on the mounting surface through the rising peripheral wall of the cap B, until the free end of the claw comes into contact with the edge of the hole. ,
The edge of the hole and the free end of the claw piece engage with each other to prevent the clip A from slipping out. Even in this state, the jaws of the free ends of the claws of the clip A and the hole edges of the mounting surface are constructed so that they do not come into direct contact with each other due to the rising peripheral wall of the cap B. Further, since the engaging claw of the clip A is similarly covered by the bag portion of the cap B, the structure is such that it does not come into direct contact with the edge of the hole on the mounting surface.

Therefore, with the paint film protection clip according to the present invention, it is possible to easily create a temporarily fixed state by simply fitting the cap B used for interposition into the clip A without holding it with each finger. By inserting the clip A into the hole in the mounting surface using the temporarily attached cap B as a guide,
The clip A can be inserted and fixed smoothly without any surface of the clip A coming into contact with the edge of the mounting hole, and in this fitted state, the clip A can be elastically deformed with a claw piece. Cap B
Due to the elastic deformation of the bag portion, the clip according to the present invention has a considerable play width, making it possible to absorb dimensional errors during attachment of the clip.
