Description

[0001]
[Industrial application fields]
The present invention relates to a fastener for detachably attaching interior parts such as a trim, a pillar, and a ceiling to an inner surface of an automobile body.
[0002]
[Prior art]
For example, as shown in FIG. 4 and FIG. 5, there has been conventionally a structure for attaching an automobile interior trim to the inner surface of an automobile body. That is, FIG. 4 shows that a metal bracket b is projected from the trim a, a resin clip c is fixed to the bracket b, and the tip of the clip c is fitted into the mounting hole formed in the body d. It is made. Further, the one shown in FIG. 5 is formed by superposing the body d and the trim a and inserting and fixing the clip c between the mounting holes.
[0003]
[Problems to be solved by the invention]
By the way, in general, automobile interior parts such as the above trim may need to be removed for attachment of optional parts, maintenance, repair or the like, but in the above mounting structure, the trim a is not detached from the body d. Although there is a possibility that the clip c may be deformed, there is a possibility that the clip c may become loose at the time of reattachment. In addition, there is a problem that the manufacturing cost of the molded product such as the bracket b and the clip c is high.
[0004]
[Means for Solving the Problems]
A removable fastener for automobile interior parts according to the present invention is intended to solve the above-described problem, and a net-like or porous sheet is interposed between two double-sided tapes coated with an adhesive on both sides. Thus, the adhesive force between the double-sided tapes is suppressed.
[0005]
The present invention is also characterized in that in the removable fastener for automobile interior parts described above, the double-sided tape is formed by applying an adhesive to an acrylic foam.
[0006]
[Action]
There is no need to pre-install mounting holes or mounting brackets on body parts, automobile interior parts, etc., and it can be easily attached at any position. In addition, since the adhesive force between the double-sided tapes can be adjusted by the hole area ratio of the sheet, it can be surely detached from the joint surface of the sheet and can be freely attached and detached. Moreover, it can be attached at a low cost and can also have a function as a spacer by appropriately selecting the thickness of a double-sided tape made of acrylic foam or the like.
[0007]
【Example】
Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows an external perspective view of the fastener before use. In FIG. 1, 1a and 1b are formed by forming an acrylic foam into a strip shape having a thickness of about 1 mm and a width of about 10 mm, and applying adhesive to both sides thereof. A pair of two double-sided tapes have a plastic net-like sheet 2 interposed between the double-sided tapes 1a and 1b. 3a is a release paper affixed to the outer surface of one double-sided tape 1a, and 3b is a release paper affixed to the outer surface of the other double-sided tape 1b.
[0008]
When the trim 5 is attached to the body 4 using this fastener, the release paper 3a is peeled off, the double-sided tape 1a is attached to the trim 5, the other release paper 3b is peeled off, and the double-sided tape 1b is removed from the body 4 Adhere to. FIG. 2 shows the state of attachment in cross section. Thus, since the body 4 and the trim 5 can be attached to be separated by the thickness of the double-sided tapes 1a and 1b, the thickness of the double-sided tapes 1a and 1b can be determined in advance as a spacer. It also has functions.
[0009]
When an external force is applied to remove the trim 5 from the body 4, the double-sided tape 1 a is strongly bonded to the trim 5 by the adhesive, and the double-sided tape 1 b is also strongly bonded to the body 4 by the adhesive. On the other hand, since the adhesive force of the double-sided tape 1a and the double-sided tape 1b is suppressed by the presence of the sheet 2, the double-sided tape 1a and the double-sided tape 1b are separated. FIG. 3 shows the situation of the double-sided tape 1a at that time. Thus, even if the trim 5 is removed, the adhesiveness of the double-sided tapes 1a and 1b is not impaired, so that the reattachment is easy. In addition to the net-like one shown in the figure, the sheet 2 may be a porous one or a non-woven fabric. Moreover, since the ratio which the double-sided tapes 1a and 1b adhere | attach directly becomes higher when the aperture ratio is large, adhesive force becomes large. Therefore, the mutual adhesive force can be appropriately controlled by adjusting the aperture ratio of the sheet 2.
[0010]
【The invention's effect】
Thus, according to the fastener of the present invention, an automobile interior part can be easily and detachably attached to an arbitrary part without adding any processing such as mounting holes to the automobile body and the automobile interior part. This is extremely useful in reducing the assembly cost.
