Description

[Detailed Description of the Invention] Technical Field The present invention relates to a clip used for attaching metal molding to an object to be attached, such as a resin bumper for a vehicle.

BACKGROUND TECHNOLOGY For example, some vehicle bumpers are made of injection molded resin such as polypropylene resin (see Figure 1), and the main body of bumper B is designed to enhance decorativeness and reinforce the edges. Approximately the entire length of the flange portion F (see Figure 2), which is formed on the top surface and projects obliquely toward the vehicle body, from the front portion _b1 to the corner portion _b2 is covered with metal molding M. There is.

Conventionally, when installing this molding M (see Figs. 2 and 3), a U-shaped molding was used, with one longitudinal edge m ₁ bent into a hook shape being provided at the base of the flange F. It is held in the receiving groove S, and the other edge m ₂ bent into an approximately inverted L shape is held in place in the holding plate 1 (Utility Model No. 57-130743).
issue). The retaining plate 1 has an L-shaped bracket 2 fitted and fixed to a rib R protruding inside the bumper body, and is supported by being screwed onto the axis of a screw 3 screwed into the rising part of the bracket 2. Adjust the L-shaped edge of molding M by adjusting screw 3.
It is attached so that the _m2 can be pulled and fixed. However,
When installing this molding, there is a risk that the screw 3 will loosen due to vibration during driving, causing rattling, or that the screw 3 will loosen and the molding M will come off, and the assembly work is also complicated and requires a large number of parts. This has the drawback of increasing costs due to the large number of

On the other hand, the present applicant has previously proposed that the widthwise edge 1 of the molding body M is bent inward in the shape of a hook.
1 and 12 are engaged with the base S of the flange part F that protrudes from the upper surface of the bumper main body, and the other edge is engaged with the flange part F with the hook 13 of the clip C fitted between the edges of the molding main body M. (Refer to Figures 4 and 5) (Jikkoi No. 2-1162). The clip C includes a main body plate part 14 that is fitted into and fixed to the molding main body M, a plurality of mounting legs 15 formed by bending from one side of the main body plate part 14, and a locking claw 13 provided at the tip of each leg part. 13, and each leg portion 15, 15 is formed so that the opposing distance from the other side of the main body plate portion is equal. Therefore, in this clip C, the flange part F of the bumper
It can be installed with one touch by fitting into the flange portion F, and since the locking claws 13, 13 are locked by sandwiching the thickness of the flange portion F, secure installation is possible. However, in clip C, each mounting leg is arranged in a line, so for example, the mounting reference dimensions of bumper flange F are relatively stable, and the error may be within ±0.5mm for 20mm. It functions satisfactorily, but the error is ±1.0mm.
If the latching claws 13, 13 are dislocated from the flange part F, or even if they are attached to the flange part F, it is expected that the latching claws 13, 13 will be loose.

DISCLOSURE OF THE INVENTION It is an object of the present invention to provide a clip that can reliably and stably attach molding even if there are dimensional variations in the object to be attached.

That is, in the clip according to the present invention, the main body plate part is fitted and fixed between the hook-shaped inwardly bent axial edges of a long molding main body, and is entirely formed of an elastic metal plate material; an engaging portion that engages with both ends of a flange portion formed to protrude from both sides in the width direction of the main body plate portion on the attached object, and at least one side of the engaging portion is provided with a spaced apart space between the attached object and the attached object. A plurality of mounting legs are formed by bending and molding according to the wall thickness dimension of the flange part,
A locking pawl is formed on the distal end side of each mounting leg, and each mounting leg is bent and formed at a different distance from the other side of the main body plate.

Embodiments The following description will be made with reference to FIGS. 1, 2, 4, and 6 to 11.

This clip C is used to attach the molding M to cover the flange portion F of the bumper body B, and is formed by bending an elastic metal plate material into a substantially C-shaped cross section to approximately match the outline shape of the flange portion F. There is. The molding M is also formed of a strip material such as a stainless copper plate into a substantially C-shape with the edges in the width direction bent inward into a hook shape.

Clip C is the edge 11,1 of molding M
2, and both sides 21 and 26 in the width direction of the main body plate part 20, which will be described later, are formed as engaging parts that engage with both ends of a flange part F protruding from the bumper B. ing. At least one side 21 of the engaging portion is integrally formed with mounting legs 22, 23 bent downward and latching claws 24, 25 bent and formed at the tip of each leg 22, 23. (See Figure 6).
The mounting legs 22 and 23 are bent according to the thickness of the flange F of the bumper B, and are provided at different intervals ₁ and ₂ from the engaging portion on the other side 26. The intervals ₁ and ₂ are determined by the bending angle (α
-β<α+β), and can be changed by bending one side at an obtuse angle or an acute angle (see FIGS. 7a and 7b). Instead of bending the mounting legs 22', 2
The distances ₁ ' and ₂ ' can also be varied by shifting the position of the base where 3' is raised (see Figure 8). These mounting legs 22, 22', 23, 2
The latching claws 24 and 25 formed at the protruding end of the holder 3' are each formed to protrude inwardly, and the tip thereof is preferably formed into an acute tooth shape (see FIG. 6).

In the clip C configured in this way, when attaching the molding M to the flange portion F of the bumper B, the molding M is fitted in advance at regular intervals in the width direction, and the molding M is fitted along with the edge 11 of the molding M on one side 26.
After the engaging portion of the bumper B is engaged with the receiving groove S formed at the base of the flange portion F of the bumper B, when the engaging portion of the other edge 12 of the molding M is engaged with the flange portion F, the latching pawl 24, 25 is pushed downward while slightly deviating outward. With that movement, the latching claws 24, 2
5 is removed from the end face of the flange part F, the mounting legs 22 and 23 come into contact with the end face of the flange part F, and the latching claws 24 and 25 engage with the lower end face of the flange part F, so that the molding M The flange part F
Can be securely installed and fixed. At that time, even if the flange portion F is formed to be shorter (-d) than the standard dimension, the mounting leg portion 22 may be
At the same time, the latch claw 24 engages with the flange portion F (the first
0), or conversely, even if it is formed to be long (+d), the mounting leg portion 23 and the locking pawl 25 can be engaged (see FIG. 11). However, in the latter case, the mounting leg portion 22 and the latch claw 24 located relatively inside are held while being deviated outward.

In addition, in the above-mentioned clip C, only the mounting legs 22, 22', 23, 2 are used as the engagement part on one side 21.
3' and latching claws 24, 25 are provided, but the engaging portions on the other side 26 can be formed in the same manner (see FIG. 9). In this case, it is desirable to offset the opposing sides 22 and 27, respectively, and the mounting legs 22 and 28 may be offset in a staggered manner.

Effects of the Invention As described above, according to the molding attachment clip according to the present invention, the molding body can be latched and fixed to an object to be attached, such as a flange of a bumper, without using screws. Furthermore, even if there is a relatively large dimensional error, it can be installed securely without wobbling or coming off.
