DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding structure, and more particularly to a molding structure for an automobile or the like.

[0002]

2. Description of the Related Art Conventionally, a door panel 1 of an automobile has been used.
The side moldings 3 to be mounted in the grooves 2 are mounted with the positioning bosses 4, 4,... Being appropriately separated from each other as shown in FIG. Are attached to the two sides of the side molding 3 along the longitudinal direction of the side molding 3, and the adhesive tapes 5, 5,.
The back (release) paper 6 is adhered to the adhesive surface on the back surface of. In the mounting operation, the backing paper 6 is peeled off, the side molding 3 is inserted into the groove 2 of the panel 1, the boss 4 is inserted into a hole (not shown) of the panel 1, and the adhesive tape is positioned. The side molding 3 is mounted in the groove 2 by 5, 5,... (For example, there is a technique as shown in Japanese Utility Model Laid-Open No. 1-70651).

[0003]

However, even when the bosses 4, 4... Of the side moldings 3 are large with respect to the center of the side moldings 3 or when the moldings are thin, the pins of the panel hole press are not required. Since it is necessary to drill a large panel hole of φ12 to 15 due to strength, positioning bosses 4 and 4
... If it is necessary to increase the size of the boss,
Since the adhesive tapes 5, 5,... Are cut off at positions 4,.
Since the tape is not connected around the boss, the side molding 3 is wavy when the side molding 3 is adhered to the panel, and particularly, the periphery of the boss of the upper side molding 3 floats with respect to the body panel 1, so that the appearance is very good. There is a disadvantage that it gets worse. Also, the tape backing paper 6 needs to be connected with the bonding backing paper 7 between the backing papers 6, 6 of the adhesive tapes 5, 5 in order to continuously peel it off, but this is troublesome and increases the cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a structure in which a back surface of a molding is provided on a back surface of the molding.
Is fixed by protruding the boss at a predetermined interval in the direction, the only setting the gouge portion to smoothly tilted outward while extending toward the boss bottom inside from the front end, the said boss bottom gouge portion mall A step that separates from the back through a space
While providing, on the back of the mall through the space
One side of the double-sided adhesive tape is adhered so as to be continuous in the longitudinal direction .

[0005]

The backing paper is peeled through the undercut, the molding is inserted into the groove of the panel, the boss is inserted into the hole of the panel, and the molding is attached to the panel with adhesive tape while positioning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. On the back of the side molding 3, the bosses 4, 4,... Are slightly offset laterally from the center line (downward in FIG. 1) and are fixed at a required distance, and the bosses 4, 4,. Side (Fig. 1
On the upper side), one side of the narrow double-sided adhesive tape 5a is adhered continuously in the longitudinal direction.

As shown in FIGS. 3 and 4, the biased side of the boss 4 is provided with cut-out portions 4a and 4b which are smoothly sloping outward from the bottom surface toward the front end thereof, respectively. , 4b are separated from the back surface of the side molding 3 via the space 3a. Thus side mall 3
One side of a double-sided adhesive tape 5b having a small width is continuously bonded in the longitudinal direction through the space 3a to the biased side (the lower side in FIG. 1) of the back surface of the tape. Reference numerals 6 and 6 denote back (release) paper sheets adhered to the back surfaces of the double-sided adhesive tapes 5a and 5b.

In the mounting operation, the backing papers 6, 6 are peeled off, the side moldings 3 are inserted into the grooves 2 of the panel 1, and the bosses 4, 4,... )
The side molding 3 is mounted in the groove 2 of the panel with the adhesive tapes 5a and 5b while being inserted and positioned. At this time, the backing paper 6 of the lower adhesive tape 5b is smoothly pulled out along the smooth inclined surface of the undercut 4a at the position of the boss 4, as shown in FIG. It is easy to do. In the above embodiment, the bosses 4, 4
The bosses 4, 4,... Are provided with the recesses 4a, 4b on one side by shifting the position of the bosses 4, 4,. The centering portions 4a, 4b may be provided on both sides of the bosses 4, 4,.... In addition, the step part 4e which forms the space 3a on the back surface of the undercut parts 4a and 4b,
When it is mounted inside, it is formed so as to be located substantially in the middle of the thickness of the panel, and the side molding 3 does not shift downward after mounting.

FIGS. 5 to 7 show a second embodiment of the present invention, and the same parts as those in the first embodiment are denoted by the same reference numerals. The bosses 4, 4,... Are fixed on the center line on the back surface of the side molding 3 at a required interval, and on both sides of the boss 4, the same recesses 4a, 4b, 4c, 4d as above are provided symmetrically with respect to the center line. The position between the undercuts 4c and 4d is also separated from the back surface of the side molding 3 via the space 3b, similarly to the position between the undercuts 4a and 4d. In the case of this embodiment, the side molding 3
One side of the double-sided adhesive tape 5a, 5b having a small width is continuously adhered to the both sides of the back surface in the longitudinal direction through the spaces 3a, 3b. The operation of the device of the second embodiment is the same as that of the first embodiment.

[0010]

As described above, according to the present invention, the boss protrudes from the back surface of the molding at a required interval in the longitudinal direction of the molding.
Is fixed by, set the gouge portion to smoothly tilted outward while extending toward the tip from the inside of the boss bottom
Only, while providing a step portion for separating the said boss bottom through the space from the back surface of the gouging portion molding, on the back of the mall one side in the longitudinal direction of the double-sided adhesive tape through said space
The backing paper is pulled out smoothly through the boss undercut, and the backing paper is easy to peel off, and the adhesive surface of the adhesive tape is exposed around the boss. Can be prevented, and the appearance of the finish can be improved.
