Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a resin clip having a structure that allows a degree of freedom in attachment and detachment of fixed parts.

[Prior Art] When fixing an insert piece of a fixed part to a body panel of an automobile or the like, generally, an iron clip or a resin clip is used, and the insert piece is fixed to the body panel via this clip. There is.

Fig. 5 shows a conventional mounting structure using iron clips, in which positioning pieces 2 are bent on both sides of the upper edge of the main body 1, which is approximately U-shaped in cross section, and the lower part of the positioning pieces 2 is bent. On the side, engaging claws 3 and 4 are provided on the outer and inner parts, respectively.
The outer locking claw 3 clamps the body panel 5 between it and the positioning piece 2, and the inner locking claw 4 bites into the outer periphery of the insertion piece 6 of the mating fixed part. This is fixed.

[Problem to be solved by the invention] The clip of the above structure is intended for permanent or semi-permanent fixation, and once the insert piece is attached to the main body.
Once it is inserted inside, it is difficult to remove it.

Incidentally, the body panel 5 includes not only parts that are permanently fixed, but also parts that require removal work even after installation.

For example, this applies to parts that are subject to heavy wear and need to be replaced frequently, and cases where some parts are replaced from pre-equipped original parts to optional parts depending on the user's characteristics.

However, since the clip with the above structure is intended for permanent or semi-permanent fixation, when an attempt is made to pull out the insertion piece when replacing parts, the locking claw 4 of the clip will be stuck on the outside of the insertion piece 6. It gets stuck firmly in the parts, making it extremely troublesome to pull it out, and if it is pulled out forcibly, the fixed part is damaged, so it cannot be used for other parts and has to be discarded. Also, if the clip is pulled out forcibly, the clip side will also become deformed (in the case of resin clips, the locking claws etc. will be damaged).
It cannot be used as a clip for new parts,
This also had to be discarded and a new clip reloaded into the mounting hole.

The purpose of this invention is to solve the above-mentioned problems, and the purpose is to provide a resin clip with a structure in which the fixed part itself will not be damaged or the clip itself will not be damaged even if the fixed part is frequently attached and detached. .

[Means for Solving the Problems] In order to achieve the above object, this invention has a clip body having a substantially U-shaped cross section that is fitted and fixed in a mounting hole formed in a body panel, and has a clip body that is fitted into a mounting hole formed in a body panel. A resin clip that is fixed to a body panel by inserting an insertion piece of a fixing part: This resin clip is formed on both sides of the opening of the main body, and has a positioning position that is placed against the surface of the body panel. a locking piece that is located at the bottom of the positioning piece and protrudes from the side of the main body and holds the body panel between the positioning piece; and a locking piece that is integrally formed at the top of the positioning piece in an expanded state. and a locking pawl that protrudes from the inside of one of the insertion guide pieces and engages with a notch formed in the insertion piece, and when the fixing part is attached, the one of the insertion guide pieces The structure is such that a guide groove for detaching the locking pawl is formed between the insertion guide piece and the insertion piece.

[Function] According to the above configuration, when installing the fixed part, if the insertion piece is inserted into the main body as in the conventional case,
The locking claw elastically engages with the notch and prevents it from coming out in this state, so it can be installed with one touch.

When removing the plug from this installed state,
When a flathead screwdriver or other insertion jig is inserted into the removal guide groove, the tip of the insertion jig comes into contact with the locking pawl and presses the locking pawl outward.

By this operation, the locking pawl is released from the side of the insertion piece, the insertion piece becomes free, and can be easily removed from the main body by a simple pulling operation.

[Example] Hereinafter, an example of this invention will be described in detail using the drawings.

FIG. 1 shows an embodiment in which this invention is applied to fixing a side sill cover of an automobile.

In the figure, 10 is a side sill that constitutes a part of the body panel formed at the bottom of the door opening;
Reference numeral 2 denotes a side sill cover that surrounds one side of the side sill 10. The surface of this cover 12 is covered with an end of a carpet (not shown) laid on the floor, and a carpet (also shown) fixed to the other side of the side sill 10 is covered. This cover 1 is a hard-hitting plate that does not
By being located on the upper surface of 2, the edge of the carpet terminal is created.

This side sill cover 12 is made of an injection molded body made of polypropylene, and a plurality of insertion pieces 14 are integrally formed at the tip of the side sill cover 12 at appropriate intervals in the longitudinal direction. A locking notch 14a is formed at the upper front surface.

The side sill 1 faces each of these insertion pieces 14.
Elongated mounting holes 16 are formed at equal intervals on the top surface of the 0, and each of the insertion pieces 14 is fixed through resin clips 18 that are fitted into the holes.

As shown enlarged in FIGS. 2 and 3, the resin clip 18 includes a clip main body 20 that has a substantially U-shaped cross section and is closed on both sides in the longitudinal direction by wall portions 20a; a plurality of pairs of positioning pieces 22 extending horizontally on both sides of the upper opening edge;
A locking piece 24 is formed on one side of the main body 20 and is formed to protrude outward from the main body 20, and a locking piece 24 is provided on the upper part of the positioning piece 22 on the one side and extends upwardly of the main body 20. a small-sized guide piece 26 , a large-sized guide piece 28 that is located on the upper part of the positioning piece 22 from which the locking piece 24 is projected and extends integrally to the upper part of the main body 20 , and this guide piece 28 . The locking claw 30 is located at the center of the main body 20 and is formed to protrude toward the inside of the main body 20.

The lower free ends of the locking claws 30 are shaped to protrude alternately with respect to the upper free ends of the locking pieces 24.

Incidentally, the large guide piece 28 has an arcuate curved portion 28a formed at the center thereof.

This curved portion 28a is designed to make the effective length of the locking pawl 30 as long as possible to obtain a resilient locking effect, while reducing the overall size of the guide piece 28. It has a curved shape,
A guide body 28b that expands outward is integrally extended to the upper edge of the curved portion 28a.

In the above configuration, first, the resin clip 18 can be fixed to the mounting hole 16 formed in the side sill 10 by simply attaching it to the mounting hole 16 with one touch.

That is, when the main body 20 is inserted into the mounting hole 16, the locking piece 24 comes into contact with the edge of the mounting hole 16,
The locking piece 24 is elastically distorted and inserted into the mounting hole 16 while being pressed against the main body 20 side.

Then, when the insertion is completed, that is, when each of the positioning pieces 22 comes into contact with the periphery of the upper surface of the mounting hole 16, the locking pieces 24, which have been distorted to the maximum, are removed from the mounting hole 16.
The upper free end is released from the edge of the side sill 10, and due to its rebound elasticity, it suddenly recovers with a clicking sound, and the upper free end contacts the inside of the side sill 10, and between this and each of the positioning pieces 22, the main body 20 is inserted into the mounting hole 16. Fixed permanently or semi-permanently in a clamped state inside the

In the fixed state, each of the guide pieces 26 and 28 is located in a state where it is expanded on both sides in the longitudinal direction of the main body 20,
If the insertion piece 14 of the cover 12 is inserted in this state, the cover 12 can be attached with one touch.

In this case as well, it is almost the same as above, and when the insertion piece 14 is inserted into the inside of the main body 20, the locking pawl 30 that projects inside is pressed outward. When the insertion is completed, the notch 14a faces the lower carpet of the locking pawl 30, whereby the locking pawl 30 rapidly recovers its elasticity and elastically protrudes into the notch 14a with a clicking sound. , it will be prevented from coming out.

When each insertion piece 14 is completely installed, the large guide piece 28 protrudes from the front edge of the cover 12, but since this part is covered with a tightening plate, it does not affect the appearance of the product. In this state, a guide groove d for releasing the locking pawl is formed in the front edge of the guide body 28b and the cover 12, and is large enough to allow the insertion of a flathead screwdriver D.

Therefore, cover 1 fixed as above
2, after removing the locking plate to expose the side of the cover 12, insert the screwdriver D into the guide groove d and press it until it hits the locking claw protruding inside the lower part of the guide piece 28. , press it outward.

As a result, the locking pawl 30 is separated from the notch, and the insertion piece 14 can be pulled out.

[Effects of the invention] As explained in detail using the embodiments above, in the case of the resin clip according to this invention, when removing the insertion piece provided on the resin clip from the attached state of the fixed part, it is necessary to use a flat head screwdriver or other tool. When the insertion jig is inserted into the detachment guide groove, the tip of the insertion jig will come into contact with the locking pawl, pressing the locking pawl outward, and the locking pawl will press against the insertion piece. Because it separates from the side of
The insertion piece is in a free state and can be easily removed from the main body by a simple pulling operation.

Therefore, according to this invention, unlike conventional resin clips intended for permanent fixation, the fixed parts can be attached and removed freely, and there is no damage to the fixed parts or the clip itself when it is pulled out. , both can be used repeatedly.
