Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a clip for fixing a molding having an inwardly bent edge with both edges bent inward to a panel member of a predetermined thickness, and is particularly applicable to a door trim of an automobile. Concerning clips suitable for fixing moldings.

Prior Art Automobile door trims include a leather type consisting of a skin, a pad, and a hardboard, and a fabric type, which is a fabric made of flocked fibers and the lower surface of the fabric is fixed to a hardboard. Clips are used to attach the elongated molding. Conventional clips have been made of metal having an anchor-like hook at one end and a head at the other end that fits inside the inside curved edge of the molding. To attach a molding to a door trim using this clip, first position the clip with the head on the inside curved edge of the molding and the anchor leg protruding from the slit-like opening formed between the inside curved edges of the molding. A predetermined number of clips are inserted into the molding, and the molding is caulked so that each clip is located at a position corresponding to a predetermined number of holes provided in the door trim. Next, the molding to which the clips were attached was placed in the holes in the door trim, and each clip was pressed into each hole to attach the molding to the door trim.

However, this installation method is labor-intensive as each clip must be slid into position through the openings at both ends of the molding, and the molding must be aligned with the hole in the door trim. It also required caulking work, which was troublesome. Additionally, fabric-type door trims have had the problem of dirt collecting and contaminating the flocked areas. Furthermore, in the case of metal clips, the tip of the anchor leg is connected to the inner
There were also cases where the panel made a metallic sound when touched.

Purpose of the invention Therefore, the purpose of the present invention is to provide a clip that can be attached to the molding without sliding, which prevents dirt from entering the hole for inserting the clip, and which eliminates the need for caulking the molding. The purpose of this invention is to provide a clip that does not generate metallic sounds.

Composition of the invention In order to achieve this purpose, according to the invention,
A clip for fixing to a panel member of a predetermined thickness an elongated molding whose both edges are bent inward to form a slit-like opening between the two edges, the clip includes a head that engages with the inwardly bent edges of the molding; , consisting of a large-diameter shaft portion of a constant height formed at the lower part of the head portion, and an anchor-like leg portion below the shaft portion, and the head portion engages inside the inner bent edge of the molding. It has a molding locking portion that fits, and a base portion that connects the locking portion to the flange and has a width that matches the width of the slit-shaped opening, and the molding locking portion is formed in a substantially rectangular shape, and the molding locking portion is formed in a substantially rectangular shape, and The short side is shorter than the slit-like opening width of the molding, the long side is larger than the opening width and approximately equal to or slightly larger than the inner width of the molding, and one of the molding locking parts A clip is provided which is characterized in that two diagonal corners remain at right angles, but the other two diagonal corners are rounded.

Embodiments Examples of the present invention will be described below with reference to the drawings.

An example of a clip according to the present invention is shown in FIGS. 1a-f. The clip 1 according to the present invention is made of an integral piece of plastic such as thermoplastic resin, and includes a head 2, a large-diameter shaft 3 formed at the bottom of the head 2, and a clip extending downward from the lower surface of the large-diameter shaft. As shown in FIG. 1f, the clip 1 is of solid symmetrical shape and can be simply and easily molded with a split mold.

The head 2 has a substantially rectangular molding locking portion 5.
and a base portion 6 that connects the locking portion 5 to the flange 3. The length l of the short side of the molding locking part 5 (FIG. 1c) is the length of the short side of the molding M (FIG. 2).
It is shorter than the width m of the slit-like opening formed between the two edges 7, 7 which are bent inwardly.
The length n of the long side of the locking portion 5 is larger than the opening width m of the molding, approximately equal to or slightly larger than the inner width o of the molding, and slightly larger than the width o. Larger is preferable. Further, as shown in FIG. 1e, the base 6 is formed into an octagonal shape with cut corners, and the short side has the same length as the short side length l of the molding locking part 5. The length p of the long side is the same as or slightly larger than the slit-like opening width m of the molding M. Furthermore, the upper surface of the head 5 is provided with a protrusion 8 that curves upward. Height q from the top of this protrusion 8 to the bottom surface of the molding locking part 6
(FIG. 1b) is slightly larger than the internal height r of the molding M (FIG. 2).

As shown in FIGS. 1c and 1e, the molding locking portion 5 has one diagonally opposite corner rounded and the other diagonally opposite corners formed at right angles. This right-angled corner allows
When rotating the clip head 5 within the molding M, the rotation angle is limited to 90°. In addition, the lower surface of the rounded corner of the locking portion 5 is as shown in FIG. 1b.
A slope 5' is formed so that the thickness of the locking portion 5 becomes thinner toward the corner. The formation of this slope 5' allows the lower surface of the locking part 5 to slide along the inner surfaces of the inner bent edges 7, 7 of the molding M, making it easier to rotate the clip and increasing the engagement force as it rotates. can be raised.

The large-diameter shaft portion 3 is a circle or a slightly oval shape that is larger than the base portion 6 but slightly smaller than the outer width of the molding M, and has an outer diameter approximately equal to the mounting hole 20 of the panel member p (FIG. 3) such as a door trim. The height of the pillar is sufficient to close the mounting hole 20 of the panel member p. The upper surface of this large diameter shaft portion 3 acts as a flange facing the molding locking portion 5, and the entire large diameter shaft portion acts as a plug for the attachment hole 20. Note that, in order to improve insertion into the mounting hole 20, it is preferable that the lower surface has a slope 9.

The anchor leg 4 includes a plate-shaped support 10 and this support 1.
It consists of locking legs 12, 12 extending upwardly from the tip 11 of the locking leg 12, and each locking leg 12 has a locking claw 13 formed at its tip. The leg strut 10 has the same width at the part connected to the large-diameter shaft 3 and tapers toward the tip 11, and the tip is rounded so that it can be easily inserted into the mounting hole 20 (Fig. 3). It is preferable that it be done as follows. Also, the locking leg 12
The opening direction of the clip is preferably oriented in the longitudinal direction of the molding M after the clip is fixed to the molding M. This is because the holes in panel members P such as door trims are often formed in an oval shape rather than a circle in order to absorb the mounting pitch deviation of the molding M, and this improves the locking force in the oval hole. be. Another reason is that if each locking leg 12 is open in the width direction of the molding M, it will wobble in the width direction when inserted, making insertion difficult. Locking leg 12
This is because when it is open, it is stable and does not wobble.

FIGS. 2 and 3 show how the molding M is fixed to a panel member P such as a door trim using the clip 1 according to the present invention configured as described above.
As shown in the figure.

In FIG. 2, the short side of the head 2 (specifically, the molding locking part 5) of the clip 1 is pointed toward the slit-shaped opening formed between the inner bent edges 7, 7 of the molding M. Insert in the direction. Since this short side is shorter than the opening width m, it can be inserted without any hindrance. In the inserted state, hold the leg part 4 and rotate it 90 degrees. As a result, the locking legs 12, 12 are rotated from a position where they extend in the width direction of the molding M to a position where they extend in the longitudinal direction. This condition is shown at the top of FIG.

When rotated 90 degrees, since the length n of the long side of the locking part 5 is slightly larger than the inner width o of the molding M, the edges 7, 7 of the molding M are pressurized outward, and The protrusion 8 protrudes upward and has a height q
(FIG. 1b) is larger than the internal height r of the molding M, so as the locking portion 5 rotates along the slope 5', the projection 8 presses the upper surface of the molding. Furthermore, the long side of the base 6 also comes into contact with the end surface of the inner bent edge 7 of the molding M. Therefore,
By simply rotating the clip 1 by 90 degrees, the clip will be firmly fixed to the molding M. In this way, a predetermined number of clips can be placed in a predetermined position on the elongated molding M without the need for sliding.
It can also be easily installed without the need for caulking.

After a predetermined number of clips 1 are attached to a predetermined position on the molding, the legs 4 of the clips 1 are inserted into a predetermined number of holes 20 in a panel member P such as a door trim (FIG. 3). The panel member P is, for example,
Skin 21, elastic pad 22 and hardboard 23
shall consist of. The state after installation is shown in FIG. During insertion, the tips 11 of the legs 4 are rounded, so they advance smoothly, and the panel member locking legs 12, 12 are bent inward to lock the panel member P when inserted. The legs 12 do not cut into the holes 20, and the legs 4 of the clip 1 are inserted smoothly as they are. Even after the lower surface of the large-diameter shaft portion 3 comes into contact with the skin 21 of the panel member P, the clip 1 is strongly pressed. In this case, a slope 9 is formed on the lower surface of the shaft portion 3.
, which reduces the repulsive force when pressing the pad 22, making it easier to insert the clip in this respect as well. When the locking claws 13, 13 come out from the bottom surface of the hardboard 22, the locking legs 12, 12, which had been bent inward, protrude outward due to their own elasticity.
The clip 1 is fixed to the panel member P by the locking pawl 13 and the lower surface of the large diameter shaft portion 3. If an elastic body such as pad 22 is present, the clip will be firmly fixed to the panel member. This fixation results in the molding being fixed to the panel member.

FIG. 4 shows a completed state in which the molding M has been installed using the aforementioned leather type door trim as the panel member P. FIG. 5 shows flocking on the textile fabric 25,
A fabric-type door trim formed by fixing a textile fabric 25 to a pad 22 and the pad to a hardboard 23 is used as a panel member P, and a molding M is attached thereto. In any mounting state, the clip 1, especially the shaft 3, acts as a plug to close the mounting hole 20 of the panel member P, and can prevent air from flowing through the hole 20. 26 will no longer be contaminated. In addition, in FIGS. 4 and 5, I indicates the inner panel of the automobile door.

Effects of the invention According to the clip according to the invention, which has the above-described structure, the head can be easily inserted into the molding at a predetermined position, and the clip can be inserted into the molding simply by rotating the clip shaft 90 degrees with a weak force such as a finger. fixed to the deing,
Since the clip is prevented from rotating more than 90 degrees during and after the rotation, the clip will not become unfixed to the molding and its fixation will be reliably maintained. Therefore, there is no need to insert the molding through the opening at the end of the molding, slide it, and caulk it at a predetermined molding position.

In addition, the large diameter shaft portion can be inserted into a mounting hole of a panel such as a door trim to close the hole and prevent dirt and the like from entering through the hole. Furthermore, the anchor-like legs of the clip can absorb pitch misalignment between the molding and the panel member to which it is attached.
