Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin foam molded article obtained by laminating and molding a lining substrate as a resin foam layer integrally with a skin material, such as a door lining for an automobile. The present invention relates to a fastening and fixing structure of a component for a resin foam molded product which is applied for fastening and fixing another component such as a pull pocket with a screw member.

[0002]

2. Description of the Related Art Conventionally, a pull pocket 1 as shown in FIG.
As a separate example, the case where the door lining 2 to be mounted is screwed and fixed, the door lining 2
Due to the peculiarities of the resin foam molded product in which the lining board 2a of FIG. 6 is integrally foamed with the skin material 2b as a resin foam layer, the resin or metal screw receiving metal fitting 3 as shown in FIG. The door lining 2 is formed by inserting the pull pocket 1 into the door lining 2 through the opening 5 provided in the armrest portion 4 of the door lining 2, and the lower side of the pull pocket 1 is attached to the screw receiving fitting 3 The lining board 2a is fastened and fixed with a screw 6 that is screwed into.

However, the fastening and fixing structure of the parts requires an extra screw receiving metal fitting, and since the screw receiving metal fitting is insert-molded on the lining board, not only is it troublesome to manufacture the door lining itself. , It takes a lot of time to align the screw with the screw fitting when screwing the pull pocket.

DISCLOSURE OF THE INVENTION The present invention reduces the number of parts required for fastening and fixing another component, does not require time and effort in manufacturing a resin foam molded product and when fastening another component, and is a member to be attached. It is an object of the present invention to provide a fastening and fixing structure for a component to a resin foam molded article, which enables a separate component to be firmly tightened and fixed even if the resin foam molded article is.

[0005]

In the structure for fastening and fixing parts to a resin foam molded article according to the present invention, a resin foam molded article in which a lining substrate is laminated integrally with a skin material as a resin foam layer like an automobile door lining. Is a mounted body, and the spiral-shaped spiral shaft extending from the head of the screw member is formed on the layer of the resin foam molded product in order to tighten and fix another part such as a pull pocket to the resin foam molded product with the screw member. It is constructed by directly screwing into the inside and tightening and fixing a separate part from the head part to the resin foam molded product.

[0006]

In the structure for fastening and fixing parts to the resin foam molded product of the present invention, the parts are tightened and fixed with the head by screwing the spiral spiral shaft directly into the layer of the resin foam molded product. Therefore, the receiving member for the spiral shaft is not required, and of course, the labor required for insert molding of resin foam molded products, screw hole alignment, and the like is not required. Also, since the spiral spiral shaft is swung into the layer of the resin foam molded product, it is possible to firmly tighten the separate part with the head even if the mounted object is the resin foam molded product. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
Shows a door lining 10 for an automobile as a resin foam molded article to be attached, and a pull pocket 11 as another component to be attached. Of these, the door lining 10 is based on a lining substrate 10a formed by resin molding with soft or semi-rigid urethane foam or the like, and a laminated material of polyvinyl chloride and polypropylene foam (PPF), a laminated material of thermoplastic elastomer and PPF, etc. Skin material 10b
It is a resin foam molded product that is laminated and deposited by vacuum molding or the like.

For the automotive door lining 10,
The pull pocket 11 is inserted inside the door lining 10 from the opening 12a provided on the upper surface of the door armrest 12, and is attached to the door lining 10 by engaging the overhanging flange 11a around the opening edge. Further, the pull pocket 11 is fastened and fixed to the door lining 10 by bringing the lower flange portion 11b into contact with the lining board 10a of the door lining 10 and tightening it with a screw member 13. In the pull pocket 11, only a through hole 11c through which a spiral shaft of a screw member 13 described later is inserted is provided in the lower flange portion 11b.

As the screw member 13, as shown in FIG. 2, a screw member 13 having a head portion 13a and a spiral spiral shaft 13b extending from the head portion 13a is used. The head portion 13 may be a round shape with a hole or a flat shape with a hole as shown in FIGS. 3 and 4, and may be appropriately selected according to the component to be the mounting body. The number of spiral turns of the spiral shaft 13b can be appropriately set to two or three turns, and the tip side may be sharpened at an acute angle.

Using the screw member 13, the spiral shaft 13
b is inserted through the through hole 11c provided in the lower flange portion 11b of the pull pocket 11, and the door lining 1
The lower flange portion 11b of the pull pocket 11 can be fastened and fixed to the head portion 13a by screwing it into the 0 lining substrate 10a. With this screw member 13, since the spiral shaft 13b is swung into the layer of the lining substrate 10a to be caught, a strong tightening force is exerted even if the lining substrate 10a of the door lining 10 is a soft or semi-hard resin foam layer. it can. Therefore, the pull pocket 11 can be firmly tightened and fixed to the lining substrate 10a only by the screw member 13 so that the pull pocket 11 does not come off even after many years of use.

In the above-described embodiment, the automobile door lining is exemplified as the resin foam molded product and the pull pocket is exemplified as the separate component.
Even other resin foam molded products can be widely applied to tighten and fix other parts.

[0012]

As described above, according to the fastening and fixing structure of parts for the resin foam-molded product of the present invention, a separate part can be attached to the resin foam-molded product without troublesome work with only a small number of screw members. Can be firmly tightened and fixed.
