Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a bracket for attaching a clip to be fixed to the back surface of an interior part of an automobile.

<Prior art and its problems> For example, in order to attach automobile interior parts such as center pillars and door trims to the car body panel, resin clips are attached to the back side of these interior parts, and this resin clip is attached to the car body side. The automobile interior parts are attached to the vehicle body panel by press-fitting them into the mounting holes.

That is, as shown in FIG. 6, a bracket 1 for attaching a resin clip is fixed to the back side of an interior component (not shown), and this bracket 1 is connected to a flat mounting plate 2 fixed to the back surface of the interior component, The mounting plate 2 is made up of a seating plate 3 with an embossed bulge formed at approximately the center thereof and an open end. It is formed from holes 5.

Furthermore, recently this type of conventional bracket 1
However, since it is not suitable for automatically installing a resin clip, a bracket 1 is used in which a guide rib 6 is formed protruding from the back side of the mounting plate 2 so as to match the installation trajectory of the resin clip, as shown in FIG. ' was proposed, and the present applicant filed the application earlier (Utility Application 1986).
-59565). According to the bracket 1' equipped with the guide rib 6 as described above, the head 7a of the resin clip 7 is brought into contact with the upper end 6a of the guide rib 6, as shown in FIG. 8, to make one decision in the height direction. At the same time, the resin clip 7 can be guided in the direction of the arrow in the figure to smoothly attach it to the seating plate 3 of the bracket 1', which has the advantage of enabling automation and significantly improving productivity.

However, in order to mold the bracket 1' equipped with the guide ribs 6, it is usually not possible to mold with a split type injection mold consisting of male and female molds, and a slide core is required. ,
It has been pointed out that the mold mechanism becomes complicated, leading to a rise in product costs, and it also becomes difficult to release the product after injection molding, leading to a deterioration in product yield.

<<Purpose of the invention>> This invention was made in view of the above-mentioned circumstances, and the object of the invention is to provide a clip mounting bracket equipped with guide ribs that is ideal for automatic resin clip equipment, A bracket for attaching clips that enables molding with a simple mold structure that does not require a slide core, and can be expected to significantly reduce costs by allowing good product release.It also greatly simplifies product removal work. Our goal is to provide the following.

<Structure and Effects of the Invention> In order to achieve the above object, the clip attachment bracket according to the present invention includes an opening into which the clip is inserted, and a locking hole communicating with the opening and locking the clip, A clip seating part formed in an embossed shape, a mounting plate extending around the lower end of the clip seating part and fixed to the back surface of the interior component, and integrally formed on the outer surface of the side wall of the clip seating part. , and a guide rib that is parallel to the upper surface of the clip seating portion and has a lower guide surface.

That is, according to the above structure, the guide rib for guiding the clip is integrally formed on the outer surface of the side wall of the clip seating part, and since this guide rib is not set below the clip seating part, Since the clip seating part does not have an undercut shape, the bracket of the present invention can be molded using a simple injection mold consisting of male and female molds that do not require a slide core, reducing mold costs and molding costs. It is inexpensive and can be expected to significantly reduce the cost of the molded product, and since no slide core is required, it has the effect of facilitating smooth product release work when taking out the molded product.

<Description of Embodiments> Hereinafter, embodiments of the clip attachment bracket according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the first bracket for attaching the clip of the present application.
FIG. 2 is an explanatory diagram showing the clip attachment operation in a state where the bracket is fixed to an interior component; FIG. 3 is a cross-sectional view showing the split mold configuration for molding the bracket; FIG. FIG. 5 is a perspective view showing another embodiment of the bracket of the present invention.

In FIG. 1, a clip attachment bracket 10 according to the present invention has a clip seating portion 11 that is bulged in an embossed shape and provided with a flat upper surface 11a so that a resin clip (not shown) can be stably retained. The clip is horizontally extended on the outer periphery of the lower end of the clip seating portion 11 (in this embodiment, at three locations on both sides of the front end and the rear end), and is fixed by conventional fixing such as ultrasonic welding to the back side of an interior component (not shown). It is generally composed of a mounting plate 12 fixed by means, and a guide rib 15 integrally formed on the outer surface of a side wall 14 on the side of the opening 13 formed in the clip seating portion 11.

Further, the clip seating portion 11 has an opening 1.
Insertion groove 1 for inserting and locking the clip from 3
6. A locking hole 17 is formed respectively, and the upper end surface 15a of the guide rib 15 is parallel to the upper surface 11a of the clip seating part 11 and is set one step lower. The upper end surface 15a follows the guide locus of the clip, and in this example, the side wall 14 is set in an inclined shape in order to ensure the dimension of the guide rib 15 in the guide direction.

Therefore, as shown in FIG.
Resin clip 1 is attached to bracket 10 fixed to 8.
9, first lower the resin clip 19 in the direction of arrow A, and position the resin clip 19 in the height direction by abutting the head 19a of the resin clip 19 against the upper end surface 15a of the guide rib 15. Then slide it in the direction of arrow B,
Clip the resin clip 19 into the opening 1 of the seating part 11.
3 and then guide the resin clip 19 through the insertion groove 16 to the locking hole 17, the resin clip 19 can be easily and automatically attached to the bracket 10 of the present invention.

And the clip attachment bracket 10 of the present application.
can be molded with a simple injection mold consisting of a male die 20 and a female die 21 as shown in Fig. 3, and in the case of conventional brackets equipped with guide ribs, Compared to the case where complex molding molds were required, molding can be performed with a simple mold, and the molded product can be easily removed, resulting in significant cost reductions and improved workability in product removal work. It has effects such as.

Next, FIGS. 4 and 5 show other embodiments of the clip attachment bracket of the present invention, each showing a modified example of the guide rib 15. First, the guide rib 22 shown in FIG.
By bending the mounting plate 12 to form a flat and wide-area clip abutment surface 22a, even if the resin clip (not shown) is slightly misaligned, it is effective in absorbing the misalignment. be.

Furthermore, in the case shown in FIG. 5, two guide ribs 23 are formed to absorb the positional deviation of the resin clip as in the previous embodiment.

In both cases, the mounting plate 12 is provided along the entire lower end of the clip seating portion 11, so that it can be more firmly joined to the back side of the interior component.

Thus, as shown in various examples in the present application,
Various modifications of the guide ribs 15, 22, 23 are permitted, and it goes without saying that no particular restrictions are placed on the shape of the mounting plate 12 or the fixing means for fixing the plate 12 to the interior component.
