Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an opening peripheral treatment structure of a skin material in an opening provided in an automobile interior material.
In particular, the present invention relates to an opening peripheral treatment structure of a skin material to which a border decoration material such as an escutcheon is attached.

<Prior art and its problems> Automotive interior materials such as door trims are provided with openings for mounting inside handles, lock knobs, speakers, etc. Decorative materials such as escutcheons and speaker grilles have been installed to improve the exterior appearance.

In addition, in the above-mentioned opening, since the skin material is also opened corresponding to the opening, treatment of the periphery of the opening becomes a problem. That is, there is a problem in that the skin material slips out from the outer periphery of the edge decoration material due to shrinkage of the skin material, and the pad material and core material underneath the skin material are exposed, resulting in an unsightly appearance.

In order to solve such problems, two methods have been conventionally used.

First, the first method is to wrap the periphery of the skin material in the opening around the back surface of the core material and attach it with an adhesive or the like.

The second method is to weld the vicinity of the peripheral edge of the skin material to the core material by welding.

However, in the first method described above, a slit is provided in the opening for wrapping the skin material, and after applying adhesive to this part, the adhesive is rolled onto the back side of the core material and attached, which increases the number of man-hours. It has the disadvantage of poor work efficiency.

In addition, the second method has the disadvantage that depending on the material of the skin material, such as cloth, the material has a high melting point and cannot be melted with a welder, so it cannot be welded. When the width of the welded portion is narrow, it has been pointed out that not only does it take time to set up the welding device, but also the welding strength is weak.

<<Purpose of the invention>> The object of this invention is to provide a structure for treating the opening periphery of a skin material that can securely and easily fix the vicinity of the opening periphery of the skin material in the opening of an automobile interior material.

《Structure and effects of the invention》 In order to achieve the above objectives, the present invention has the following features:
An edge decoration material such as an escutcheon that is attached to an opening of an automobile interior material, with an appropriate distance between the outer wall and the inner wall on the back side of the edge decoration material,
A protrusion is provided so as to protrude beyond the edge of the outer wall, and a mounting piece is provided on the inner wall, so that the periphery of the opening of the skin material forming the interior material is double-walled from the protrusion and the edge of the outer wall. It is characterized in that it is pressed and fixed.

According to the above configuration, a protrusion higher than the end of the outer wall is provided between the outer wall and the inner wall on the back surface of the edge decoration material, and a mounting piece is provided on the inner wall. Therefore, when the above mounting piece is attached to the opening of the interior material, the opening periphery of the skin material forming the interior material can be double pressed and fixed by the protrusion and the outer wall edge, so that the outer periphery of the skin material is fixed. It is possible to reliably prevent slippage.

In addition, since the protrusion is provided on the edge decoration material, the vicinity of the periphery of the opening of the skin material can be pressed and fixed by the protrusion at the same time as the edge decoration material is attached to the opening, improving work efficiency. can be done.

《Explanation of Examples》 An embodiment of the present invention will be described below.

In FIG. 1, reference numeral 2 denotes an escutcheon attached to an opening for attaching an inside handle provided in the door trim 1, and the escutcheon 2 is made of an iron plate or the like having a substantially U-shaped cross section. Further, as shown in FIG. 2a, the escutcheon 2 is integrally provided with protrusions 2c at appropriate intervals on the back surface thereof.

That is, the protrusion 2c is formed by bending the inside wall 2a of the escutcheon 2 in parallel to form a flat part 2d, and by bending the edge of the flat part 2d at a substantially right angle. . A sawtooth-like uneven portion 2 is provided at the end of the protrusion 2c.
Further, as shown in FIG. 2b, the end of the projection 2c is formed to protrude vertically by an amount p from the end 2f of the outer wall 2b of the escutcheon 2. ing.

Furthermore, a mounting piece 4 is integrally formed adjacent to the protrusion 2c by vertically extending the inner wall 2a, and this mounting piece 4 attaches the escutcheon 2 to the opening of the door trim 1. It is for.

Next, FIG. 3 shows the state in which the escutcheon 2 is attached to the opening of the door trim 1, in which 5 is a core material made of hardboard or the like, 6 is a core material made of hardboard, etc.
7 is a pad material made of polyurethane or the like, and 7 is a skin material made of soft vinyl chloride or the like.

In the figure, the escutcheon 2 is attached to the opening of the door trim 1 by bending and forming the attachment piece 4 onto the back surface of the core material 5.

Further, since the protrusion 2c is configured to protrude vertically downward by p more than the outer wall 2b of the escutcheon 2 as described above, the skin material 7 is attached to the protrusion at the inner part of the escutcheon 2. Since it is pressed and fixed by the portion 2e and the outer wall end portion 2f, it is possible to prevent the edge 7a of the skin material 7 from slipping out to the outer periphery of the escutcheon 2.

Furthermore, in this embodiment, since the sawtooth-like uneven portion 2e is formed at the end of the protrusion 2c, the uneven portion 2
e bites into the skin material 7, and the edge 7a of the skin material 7
The structure is such that it is more firmly prevented from coming off.

Next, another embodiment of the present invention will be described.

In Fig. 1, 3 is a speaker grill;
It is made of synthetic resin or the like formed by injection molding or the like. As shown in FIG. 4a, this speaker grille 3 is integrally formed with protrusions 8 on the inside of the outer wall 3a at appropriate intervals on the back surface, as shown in FIG. 4b.
As shown in FIG. 2, the tip of the projection 8 projects vertically downward by a distance q from the end 3c of the outer wall 3a.

Next, FIG. 6a shows the speaker grille 3 attached to the opening of the door trim 1, and the speaker grille 3 is installed integrally with the speaker grille 3 as shown in FIG. 6b. This is done by locking the locking piece 9 to the back surface of the core material 5.

As described above, the speaker grill 3 is attached to the opening of the door trim 1.
As mentioned above, the tip of the protrusion 8 projects vertically downward by q from the end 3c of the outer wall 3a of the speaker grill 3, and the skin material 7 is located inside the outer wall 3a of the speaker grill 3. Since it is double pressed and fixed by the protrusion 8 and the outer wall end 3c, it is possible to prevent the opening peripheral edge 7a of the skin material 7 from slipping out to the outer periphery of the speaker grille 3.

In the second embodiment, the tip of the protrusion 8 is formed into a substantially flat shape, but as shown in FIG. It may be bitten in to provide a stronger retention.
