DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing jig for forming a plate-like decorative material used as an interior material of a vehicle, a house, and the like, and a method of forming a plate-like decorative material using the pressing jig.

[0002]

2. Description of the Related Art As one type of plate-like decorative material, there is a type in which a skin material is adhered to one side surface of a substrate having a groove at a predetermined portion.
There is a vehicle door trim as shown in US Pat. No. 037 and shown in FIGS. The board 30 of this door trim
A general area 31 and an ornament area 32 are formed on one side surface, and a groove 33 having a considerable depth is provided to clarify the boundary between these areas. And
The skin material adhered to the substrate 30 is pushed into the groove,
A so-called grained structure is formed.

[0003] By the way, a known vacuum forming method is used to attach a skin material to one side of such a substrate. However, since the wood grain structure of the groove cannot be formed only by the vacuum force,
As shown in FIGS. 5A and 5B at the same time as the vacuum forming, when a portion corresponding to the groove 33 of the skin material 34 is pressed into the groove 33 to manufacture a wood grain structure, a pressing jig 35 is used. Is used.

[0004]

However, in the above-mentioned manufacturing method, the surface material pushed into the groove of the substrate by using the pressing jig has a high stretching state and a large restoring force. 5C, the cover pad constituting the skin material is torn as shown in FIG. 5C, and the skin material rises from the groove. In particular, if there is a variation in the shape of the substrate, a displacement between the substrate and the jig, or the like, the skin material cannot be adhered in the groove with a uniform pressing force by the pushing jig, which may cause peeling of the adhesive.

When the width of the pressing jig is large, it is necessary to accurately position the substrate and the pressing jig.
On the other hand, when the width of the pushing jig is narrow, as shown in FIG. 6, the skin material adheres to the bottom of the groove, and the side surface floats and is not adhered to the bottom of the groove. The grained structure cannot be formed. In this case, since a large pressing force of the pushing jig is applied only to the portion of the skin material that comes into contact with the bottom of the groove, the foam layer of the skin material is crushed, and air is generated from the foam layer. , And a convex portion due to an air pocket appears on the surface layer of the skin material, which may impair the design. Accordingly, the present invention solves these problems, and provides a pressing jig used for forming a plate-like decorative material having a wood grain structure in which a skin material is securely adhered to a groove portion of a substrate in a good appearance. And a method for forming a plate-shaped decorative material using the pressing jig.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a method of forming a plate by pressing a portion of a skin material adhered to one side surface of a substrate having a groove at a predetermined portion, which is opposed to the groove, into the groove by sticking. In a pressing jig for forming a plate-like decorative material for forming a decorative material, a pressing portion of the pressing jig is made of a flexible material that is deformed in accordance with a bottom cross-sectional shape of the groove. Further, as a method of forming a plate-shaped decorative material using the pushing jig, by pressing a flexible material of the pushing jig, the outer periphery of the flexible material is pressed against the skin material, and the skin material is pressed. It is characterized by being pressure-bonded to the inner surface of the groove.

[0007]

According to the pressing jig for forming a plate-like decorative material of the present invention and the method for forming a plate-like decorative material using this pressing jig, the pressing portion of the pressing jig is made of a flexible material. Then, since it can be deformed according to the cross-sectional shape of the groove of the substrate, the skin material is deformed so as to be crimped to the bottom of the groove of the substrate, and the skin material is securely crimped not only to the bottom of the groove but also to the side surface of the groove. A wood grain structure can be formed. Also, even if there is a variation in the shape of the substrate and the displacement between the substrate and the pushing jig, the pressing portion of the pushing jig is deformed according to the shape of the bottom of the groove, so these variations and displacement are absorbed. A uniform pressing force can be applied to the skin material of the groove.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a pressing jig 1 according to an embodiment of the present invention.
In the perspective view of FIG. 0, the pushing jig 10 includes a jig main body 11 and a pressing portion 12 made of a flexible material and attached to a lower end thereof. The jig body 11 is a metal plate having a width of 2 to 3 mm using brass or the like, and the pressing portion 12 is made of a rod-shaped flexible material having a height of 5 to 6 mm and a width of 3 to 3.5 mm. . Here, a rubber material is preferable as the flexible material. For example, semi-rigid rubber having an Aska C hardness of about 10 to 30 can be used.

Next, the pushing jig 10 shown in FIG.
A method of forming a plate-shaped decorative material having a wood grain structure using the method will be described with reference to FIG. First, a wooden material in which the groove 21 is formed by applying a conventionally known vacuum forming method,
A skin material 22 such as a PVC material is adhered to a resin-based substrate 20,
At the same time, the skin material 22 is pushed into the groove 21 and the jig 10 is pressed.
Indicates the state of being pushed in. Here, pressing part 1
2 is deformed in accordance with the shape of the bottom of the groove 21 by the pressing force of the pushing jig 10, and presses the skin material 22 against the groove 21 to be pressed.

The formation of the wood grain structure of the plate-like decorative material having the substrate 20 and the skin material 22 adhered thereto is performed by using the pressing jig 10 having the pressing part 12 made of a flexible material. It is possible to form a wood grain structure in which the groove 22 is securely pressed not only on the bottom of the groove 21 but also on the side surface of the groove 21. In addition, variations in the shape of the substrate 20
Even if the pushing jig 10 is displaced, the flexible material as the pressing portion 12 of the pushing jig 10
Since it is deformed in accordance with the shape of the bottom of the groove, these variations and displacement can be absorbed, and a uniform pressing force can be applied to the skin material 22 of the groove 21. Therefore, since the pressing force of the pressing jig 10 is not applied to only a part of the skin material, the foam layer of the skin material is not crushed and air is not generated from the foam layer, and the air layer is formed on the surface layer of the skin material. The projections do not appear and impair the design of the plate-shaped decorative material.
