Description

[Detailed description of the invention] This invention relates to a structure for pasting sheet materials.

For example, in automobile interior materials, texture,
A flexible sheet material is sometimes pasted to cushion the impact. Conventionally, problems when pasting this type of sheet material are mainly problems of the strength of pasting and end treatment of the sheet material. In order to improve the adhesion strength, a method is often adopted in which a vacuum forming method is used to adhere the sheet material to the base material while strongly suctioning it. However, since vacuum forming equipment is large, the work is large-scale and complicated.
Furthermore, even if the surface of the sheet material is decorated with a decorative pattern of irregularities such as wrinkles, the pattern may disappear due to strong suction and stretching. In addition, regarding the issue of end treatment, when pasting sheet materials, the appearance will be damaged if the sheet material is pasted untreated, so the end portions must be neatly cut, which increases the number of man-hours. This will make the work more complicated.

Therefore, the present invention aims to provide a sheet material pasting structure with excellent pasting strength and good appearance.

To achieve this objective, the present invention is constructed as follows. That is, in a structure for attaching and fixing a flexible sheet material to a base material,
The sheet material has side pieces facing downward on both sides thereof, and is attached from the upper side to the overall U-shaped core having locking claws at appropriate positions, and the end portion of the sheet material is attached by being folded into the inside of the side piece, and a pair of grooves are formed along the longitudinal direction on both sides of the upper surface of the base material into which the side piece portion into which the sheet material is folded can be fitted. The structure is such that an insertion hole into which the locking pawl is hooked is bored.

Therefore, according to the present invention, the sheet material is attached to the core with its end portion folded inside the side pieces. Therefore, even if the terminal is not neatly trimmed, the appearance will not be spoiled. In this state, if the sheet material is fitted into the groove of the base material and hooked with the locking claw, the sheet material and the core are firmly fixed, thereby reliably preventing the sheet material from peeling off. .

Hereinafter, embodiments embodying the present invention will be described in detail based on the drawings.

In the drawing, 1 is a console made of synthetic resin that is installed between the driver's seat and the passenger seat in a car, and includes a shift lever L and a console box B.
An armrest portion A is set between the two. In this example, the armrest portion A is used as a base material, and the sheet material 3 is attached thereto via the core 2.

The core 2 is formed by bending a thin metal material (iron plate) so that it can fit into the armrest portion A. That is, the left and right side portions of the long side of the core 2 are bent diagonally downward to form an inclined side 4, and the portion below the inclined side 4 is further bent perpendicularly to form a hanging portion with the side piece 5. Furthermore, a pair of locking claws 6 are formed at the front and rear portions of both side pieces 5, respectively, to protrude downward.

In this example, the flexible sheet material 3 is made of polypropylene or polyethylene foam, and is formed to be sufficiently larger than the core 2. Further, although not shown in detail, cuts are made at appropriate locations in the sheet material 3, and the core 2
It is possible to fold it to the back side. Furthermore, near each corner of the sheet material 3,
Slits 3a to 3a into which each locking pawl 6 is inserted pass through.

The armrest portion A is formed into a frame shape that opens downward, and a sheet material 3 is provided at the boundary between the armrest surface 7 and the surface corresponding to both inclined sides 4 of the core 2.
The step 8 is provided in consideration of the thickness of the folded portion. Furthermore, grooves 9 are recessed along the longitudinal direction on both left and right sides of the armrest portion A, into which both side pieces of the core 2 with the sheet material 3 attached can be fitted. In addition, a core 2 is provided in both groove portions 9.
An insertion hole 10 into which each of the locking claws 6 can be inserted is penetrated.

Next, the procedure for pasting the sheet material 3 will be explained.

First, double-sided adhesive tape 11 is pasted on the sheet material 3 or core 2 at an appropriate location. Under this condition, the sheet material 3 is placed over the top surface of the core 2, and the excess portion (terminal portion) is folded into the back surface along the not-illustrated cut. Thereby, the sheet material 3 is attached to the core 2 with the end portion folded. However, at this time, each locking claw 6 is exposed from the sheet material 3.

Next, by fitting the side pieces 5 of the core 2 into both grooves 9 while fitting the locking claws 6 into the insertion holes 10 of the armrest part A, the sheet material 3 and the core 2 are brought into close contact with the armrest part A. covered with. Thereafter, by folding back each of the locking claws 6 inward, the sheet material 3 and the core 2 are reliably assembled to the armrest portion A.

As described above, in the pasting structure of this example, the sheet material 3 is not pasted directly to the armrest part A, but once pasted to the core 2, it is attached to the armrest part A by the locking force of the locking claw 6. Since it was decided to fasten the sheet material 3 to the armrest part A, even by using a simple adhesive means such as double-sided adhesive tape 11.
It does not peel off easily, and even if a decorative pattern such as a wrinkle is applied to the surface of the sheet material 3, it will not disappear during the pasting process. Furthermore, by interposing the core 2, the strength against vertical loads can be improved, so it can be said that the structure is suitable from the viewpoint of an armrest. Furthermore, since the end portion of the sheet material 3 is folded inside the core 2 and hidden, no complicated end treatment is required, and therefore the work is simple.

In addition, in this example, a slit 3a is provided in the sheet material 3, and the locking claw 6 is inserted through the slit 3a.
The attachment may be performed without providing slits in the sheet material 3. That is, the sheet material 3 including each of the locking claws 6 is pasted on the surface of the core 2, and the sheet material 3 is bent inward between the front and rear corresponding locking claws 6. After doing so, insert each locking claw 6 with the sheet material 3 pasted into the insertion hole 10,
This may be caulked.
