Is fixed.

[0005]

As described above, according to the conventional method of mounting the trunk lid opener 5, the plate 6 and the bracket 7 for supporting the trunk lid opener 5 are formed before the skin material 3 is vacuum formed. Therefore, the vacuum forming die 8 needs a clearance for avoiding the bracket 7, so that a space 9 is generated,
When the skin material 3 is vacuum-formed, an excessive tensile force acts on the skin material 3 due to the space portion 9, and there is a possibility that appearance defects such as grain flow of the skin material 3 may occur.

In order to solve this problem, a vacuum molding die 8 is used.
Attempts have been made to mount a top or the like in the space 9 described above, but in such a case, a top mounting operation or the like is required, and there is a drawback that the workability is reduced and the cost of the mold is increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of attaching a small part such as a trunk lid opener to an interior part formed by vacuum forming. And

[0008]

In order to achieve the above object, the present invention provides an opening in a trim part obtained by integrally attaching a skin material to the surface of a core material by vacuum forming, and a small part in this opening. In the method of attaching small parts, the opening is opened in the core material, the plate is fixed to the edge of the opening, and the skin material is integrally adhered to the surface of the core material by vacuum forming, and then the back side of the core material The bracket is fixed to the plate from above, a small component is inserted into the opening, and the bracket is supported and fixed by the bracket.

[0009]

As is clear from the above configuration, the bracket for supporting and fixing small parts is a method in which a skin material is vacuum-formed on the surface of a core material and then fixed to a plate previously fixed to the back surface of the core material. Therefore, when vacuum-forming the skin on the surface of the core material, it is not necessary to set the space for the escape of the bracket in the vacuum-forming mold, so when the skin is vacuum-formed, the skin near the opening is excessive. It does not cause poor appearance.

Further, there is no need to mount a frame for escaping the space in the mold.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a mounting method of a small component according to the present invention.

As an embodiment, a method of mounting a trunk lid opener on an automobile door trim will be described.

FIG. 1 is a sectional view showing a state in which a trunk lid opener is mounted on an automobile door trim, and FIGS. 2 to 4 are sectional views showing steps of a method of mounting the trunk lid opener of the present invention. FIGS. 5 to 7 show each embodiment in which the method of fixing the plate and bracket used in the method of the present invention is changed. FIGS. 5 and 6 are perspective views showing a second embodiment of the method of the present invention. FIG. 7 is a sectional view showing a third embodiment of the method of the present invention.

First, a first embodiment of the method of the present invention will be described with reference to FIGS.

Referring to FIG. 1, an automobile door trim 10 is shown.
Is composed of a core material 11 made of a wooden core material and a skin material 12 integrally adhered to the surface of the core material 11 by vacuum forming. The formed armrest portion 13 is formed,
An opening 14 for mounting the trunk lid opener 20 is provided in a lower half portion of the armrest portion 13.

The trunk lid opener 20 is made of a synthetic resin injection-molded body. The support structure of the trunk lid opener 20 is supported by a plate 30 and a bracket 40 fixed to the back surface of the core material 11.

The present invention relates to an automobile door trim 1 having a skin material 12 adhered to the surface of a core material 11 by vacuum forming.
The method is characterized in that the trunk lid opener 20 can be easily attached to the trunk lid opener 20.

Hereinafter, a method of attaching the trunk lid opener 20 will be described step by step with reference to FIGS.

First, as shown in FIG. 2, the core material 11 is formed into a required shape in a hot press molding die (not shown), and an opening 14 for mounting the trunk lid opener 20 is formed. Opening 14
A metal plate 30 is fixed to the back side of the core material 11 along the edge of the core member 11 to enhance rigidity.

The means for fixing the plate 30 includes:
A burring claw is cut and raised in the plate 30, and the burring claw can be firmly fixed by biting into the core 11.

Next, as shown in FIG. 3, the skin material 12 is integrally attached to the surface of the core material 11 to which the plate 30 is fixed by vacuum forming.

At this time, since the bracket 40 is not fixed to the core member 11, there is no need to provide a space for escaping the bracket in the vacuum molding die 50 as in the prior art. Is not excessively stretched at a position corresponding to the opening 14 of the core material 11, and it is not necessary to install a top in a vacuum forming die as in the related art.

Thereafter, as shown in FIG. 4, the terminal of the skin material 12 is wound along the edge of the opening 14 of the core material 11 and the mounting hole 41 of the metal bracket 40 and the mounting hole 31 of the plate 30 are inserted. Screw the screw 60 to the bracket 40
And the plate 30 are fixed.

Then, the trunk lid opener 20 is inserted into the opening 14, and the screw 60 is screwed into the mounting hole 42 of the bracket 40, so that the trunk lid opener 20 is firmly fixed.

As described above, according to the method of the present invention, the bracket 40 is fixed to the core member 11 and the plate 30 after vacuum forming of the skin material 12. The skin material 12 at a considerable portion is not excessively stretched, and appearance defects can be prevented as much as possible.
There is an advantage that workability is improved, for example, the trouble of mounting a frame on the O is eliminated.

Next, FIGS. 5 and 6 show a second embodiment of the method of the present invention, in which a notch 32 is provided in a plate 30 and a locking claw 43 is formed in a bracket 40. This is an embodiment in which the bracket 40 is securely attached with one touch.

According to the present embodiment, the work of attaching the bracket 40 to the plate 30 can be performed with one touch.
Workability is further improved.

As shown in FIG. 7, a rivet 61 may be used to fix the bracket 40 to the plate 30, and there is an advantage that simplification of the mounting operation by the rivet 61 can be expected as compared with the screwing method.

In the embodiment described above, the trunk lid opener 20 mounted on the door trim 10 for automobiles is used.
However, the present invention is not limited to the door trim 10 and may be any interior component formed by vacuum forming. The trunk lid opener 20 may be any small component as long as it is supported and fixed to the bracket. I do not care.

[0030]

As described above, according to the method of the present invention, the following special effects can be obtained.

(1) The bracket for supporting and fixing the small parts is attached to the core material after the skin material is vacuum-adhered to the core material. Therefore, when the skin material is vacuum-adhered, a space is set in the vacuum molding die. However, there was no appearance defect due to excessive elongation of the skin material induced by the space, and the surface of the skin material was subjected to texturing,
This has the effect that surface defects such as grain disappearance can be prevented, and a beautiful surface appearance can be obtained.

(2) After the skin material is vacuum-formed on the surface of the core material, the bracket for supporting and fixing the small parts is fixed to the back surface of the core material, so that a frame for filling the space in the vacuum molding die is unnecessary. Thus, the time and effort required for mounting the frame can be saved, the workability can be improved, and the cost of the mold can be reduced.
