Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foam molded article provided with a means for hanging onto another member, such as a foam molded article used for an automobile instrument panel bat, and a method for manufacturing the same.

As shown in FIG. 1a, an automobile instrument panel pad 1 includes an outer skin 1a (for example, a vinyl chloride sheet), a foam body 1b (for example, polyurethane foam), and a reinforcing insert material (for example, a steel plate) embedded in the foam body 1b. 1c, and is hooked to a retaining plate 2 on the automobile side, as shown in FIG.

Therefore, it is necessary for the instrument panel pad 1 to be provided with a latching means, and conventionally, as shown in FIG.
A bolt 3 serving as a hanging piece was attached to c, and the bolt 3 and nut 4 were used to lock the holding plate 2.

However, when the bolt 3 is used as a locking piece, the bolt 3 must protrude from the outer surface of the foam body 1b.

Therefore, as shown in Fig. 2, it is necessary to G-gold the 3 parts of the bolt on the foam mold, and for this purpose, a foam 1b' shown in the shaded area is attached around the bolt 3, so this foam 1b' is attached after molding. It was troublesome to have to perform finishing work to remove 1b'.

An object of the present invention is to prevent the hanging pieces from protruding during foam molding, thereby eliminating the need for removing unnecessary foam that adheres around the hanging pieces that protrude from the surface of the foam molded product. It is an object of the present invention to provide a foamed molded article equipped with a hooking means that can shorten finishing work time, and a method for manufacturing the same.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 3 is a perspective view showing a case where the foam molded article 1b according to the present invention is used in an instrument panel bat of an automobile, and FIG. 4 is a cross-sectional view taken along the line -IV in FIG.

A linear reinforcing insert material, such as a steel wire 1c, is embedded in the foam molded article 1b according to the present invention.

Hooking pieces 3 are attached to the insert material 1c at predetermined intervals.

As shown in FIG. 4a, this hooking piece 3 is attached rotatably around the insert material 1c by forming an end portion 3a into an annular shape and fitting the annular portion into the insert material 1c. In addition, the main portion 3b is buried so as to be substantially flush with the foamed molded product 1b.

Therefore, when foam molding the foam molded product 1b, the hooking piece 3
Since it is sufficient to arrange it along the inner surface of the foam mold, there is no need for special stripping for the hooking piece, and the finishing work of removing the foam at the stripping section after foam molding is done as in the conventional method. do not need.

When such a foamed molded product 1b is to be attached to another member, the attachment piece 3 is rotated and erected as shown in FIG. 4 to cause the main portion 3b to protrude from the surface of the foamed molded product 1b.

Hereinafter, FIGS. 5, 6, and 7 showing specific examples of the above-mentioned hooking piece 3 will be explained.

Figures 5a and 5b both show a hooking piece in which the main portion 3b is formed in the shape of an arrow needle and is made of wire or provided with a split groove 3c to provide elasticity.

In the case of these latching pieces 3, as shown in FIG.
If the locking piece 3 is inserted into the hole 2a, the locking piece 3 will contract when inserted and will be flattened after insertion, so that the foamed molded article 1b can be reliably hung on the other member 2.

FIG. 6a shows a hooking piece 3 in which the main part 3b is formed into a flat plate shape, and in this case, the hole 2 provided in the other member 2 as shown in FIG.
Just insert it into the tube and bend or twist the tip.

Fig. 7a shows a hanging piece in which the main part 3b is formed into a U-shape with wire, and in this case, as shown in Fig. What is necessary is to fit the clip 5 into the holder.

Next, the foam molded article 1 according to the present invention configured as described above
The manufacturing method of b will be explained.

First, the locking pieces 3 are attached to the linear insert material 1c at predetermined intervals, the insert material 1c and the locking pieces 3 are arranged at predetermined positions in the foam mold, and the locking pieces 3 are placed in the foam mold. A foamed molded article according to the present invention can be produced by placing the molded materials in contact with each other along the inner surface, and then filling a foaming mold with a molding material and foaming the molded material.

As described above, the foamed molded article provided with the latching means according to the present invention includes a linear insert material in the foamed molded article, a latching piece rotatably provided on the insert material, and a latching piece provided in the insert material. It is buried almost flush with the foamed molded body.

Therefore, there is no need for the hanging piece to protrude from the surface of the foam molded product itself during foam molding, and the foam mold also does not require a paste for the hanging piece. There is no need to remove unnecessary foam that has adhered around the piece, and finishing time can be significantly shortened.

In addition, since the hook pieces do not protrude as in the conventional case, there is no risk of the foam moldings being scratched against each other when transported or stacked for storage.

Furthermore, since a linear insert material is used, no press mold is required and the material cost is lower than when using a conventional plate-shaped insert material.
