Abstract

PROBLEM TO BE SOLVED: To secure a sufficient bonding force when a flexible spacer having a self-adhesive tape formed thereon is bent on use. SOLUTION: Double-sided tapes 5a and 5b are stuck to both fitting surfaces 4a and 4b, respectively, of a spacer body 4, and plural tape flexure-absorbing ditches 6 are formed on each fitting surface at an interval in the longitudinal direction of the spacer body. Thus, wrinkles of the self-adhesive tape, which are formed when the fitting surface having the self-adhesive tape stuck thereon is bent inward, can be absorbed by the tape flexure-absorbing ditches and are prevented from protruding from the self-adhesive surface, thereby to prevent decrease in the self-adhesion area to contact with an adherend. The self-adhesive force of the spacer arranged between the two curved surfaces does not decrease and therefore the curved surfaces of both members can be bonded together with a large adhesive force.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member fixing spacer which is interposed between two members so as to connect them.

[0002]

2. Description of the Related Art Generally, there are various fixing means for fixing one member to another member. Examples thereof include screws, fasteners, adhesive tapes, and adhesives, and they are used properly according to the shape of the fixing part.

For example, the surfaces of both members facing each other may be curved, and in such a case, if the machining is performed with high accuracy so that the curvatures of both members are matched, the manufacturing cost will increase. For this reason, a flexible spacer that is fastened at the portions where the flat surfaces face each other as much as possible, has a gap between the curved surfaces to absorb processing errors, has a thickness that fills the gap, and has double-sided tape on both mounting surfaces is used. It is advisable to connect the curved surfaces of both members via the interposing member.

[0004]

However, when the spacer is bent in accordance with the bending of the member, as shown in FIG. 5A, the double-sided tape 12 provided on the inner side of the spacer 11 is wrinkled. May occur. In such a case, since the adhesive area to the member is reduced and the overall fixing force is weakened, conventionally, when a spacer is used for such a curved portion, FIG.
Cut the spacers as shown in
It is divided into 1a to 11e to correspond to the curved shapes of both members 13 and 14. Therefore, there is a problem that the work of joining the members becomes complicated and the work efficiency is poor.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems and to secure a sufficient bonding force when the flexible spacer provided with an adhesive tape is curved and used, the present invention is intended. In this case, a flexible spacer body that can be interposed between the two curved surfaces of two members having curved surfaces facing each other, and an adhesive surface facing the front surface of each mounting surface of the spacer body that corresponds to the curved surfaces. And a plurality of adhesive tapes that are fixed to each other, and a plurality of tape bending absorption grooves are provided on at least one of the mounting surfaces that is bent inward.

According to this, the wrinkles of the adhesive tape generated when the mounting surface provided with the adhesive tape is bent inward can be absorbed by the tape flexure absorption groove, and the wrinkles protrude from the adhesive surface and come into contact with the other party. It is possible to prevent a decrease in the adhesive area.

Further, since the plurality of tape bending absorption grooves are provided on both the mounting surfaces, and the tape absorption grooves are alternately arranged on the both mounting surfaces, the tape mounting grooves are alternately arranged between the both mounting surfaces. High strength can be obtained with respect to those in which the grooves are arranged at the same position.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail based on specific examples shown in the accompanying drawings.

FIG. 1 is a perspective view of an essential part showing the usage of the member fixing spacer according to the present invention. In this member fixing spacer 1, as shown in the drawing, when the curved fixing member 2 and the fixed member 3 are joined together so that the curved surfaces 2a and 3a facing each other are aligned with each other, It is used by interposing it so as to fill the gap between the two.

As shown in the enlarged views of FIGS. 2 and 3,
The member fixing spacer 1 includes a spacer main body 4 formed in a rod shape having a trapezoidal cross section, and double-sided tapes 5a and 5b fixed to the attachment surfaces 4a and 4b, which are both inclined surfaces of the spacer main body 4, respectively. In addition, the spacer body 4 includes
A plurality of tape flexure absorption grooves 6 arranged on the respective mounting surfaces 4a and 4b at intervals in the longitudinal direction of the spacer body 4.
Are provided respectively. The tape flexure absorbing groove 6 is a V-shaped groove in the illustrated example, and each of the mounting surfaces 4a
They are arranged so that they are staggered between b.

In the member fixing spacer 1 thus formed, when the two members 2 and 3 having the curved shapes as shown in FIG. 1 are joined together, as shown in FIG. It is used in a bent state according to the curvature of both members 2 and 3. At this time, as shown in the figure, both mounting surfaces 4
Wrinkles will occur on the double-sided tape 5b that is bent inward of the a.4b (mounting surface 4b), but the portion of the double-sided tape 5b that corresponds to the tape bending absorption groove 6 can be absorbed in that groove. Therefore, it is possible to prevent wrinkles protruding outward from the surface of the double-faced tape 5b that is bent inward.

Therefore, the surface of the double-sided tape 5b (see FIG.
There is no portion that protrudes due to wrinkles in (adhesive surface to member 3 in FIG. 3), and it is possible to obtain an adhesive surface having a sufficient width that corresponds to the curved surface of the counterpart member 3, and sufficient adhesive force can be secured. .

In the illustrated example, the tape flexure absorbing grooves 6 are arranged so as to be staggered between the mounting surfaces 4a and 4b, but they are arranged at positions where they overlap each other. This is because it is possible to increase the bending rigidity with respect to the above-mentioned material in terms of strength. Further, although the tape bending absorption groove 6 is a V-shaped groove, it is for ease of processing and the shape of the groove is not limited. Further, the member fixing spacer according to the present invention is suitable for filling the gap between the curved portions between the members to bring the two members into a combined state, and the use is not limited, but especially the post-fixed parts are fixed to the curved surface of the synthetic resin product. It is suitable for fixing the aero parts to the bumper, for example.

[0014]

As described above, according to the present invention, the wrinkles of the adhesive tape, which are generated when the mounting surface provided with the adhesive tape is bent inward, can be absorbed by the tape bending absorption groove, and the wrinkles are adhered. Since it is possible to prevent the adhesive area that sticks out and contacts the other party from decreasing, the adhesive force of the spacer interposed between both curved surfaces does not decrease, and the curved surfaces of both members are bonded with a large adhesive force. can do.

Further, by arranging a plurality of tape bending absorption grooves alternately on both mounting surfaces, high strength can be obtained with respect to those in which the grooves are arranged at the same position between both mounting surfaces. Since it can be obtained, it is effective for a site having a large curvature, and versatility is increased.
