Abstract

PURPOSE:To shorten the bending process of a molding extremely by arranging a weakened part easy to bend on a base wall in the longitudinal direction. CONSTITUTION:A belt shape fastener forms a notch or a thin groove part 15 as a weakened part 14 in the longitudinal direction during an extrusion molding on the surface adhering on the inner periphery of a hollow by the both face adhering tape on a base wall 1. Accordingly, a lower end part of the base wall 1 in a part on which a step shaped projecting part 13 is positioned and a folded wall 2 are cut off and also the lower part 1' of the base wall can be bent easily and orthogonally bordering a notch 15 by forming a gap 16, the upper end of which reaches the notch 15, on the lower part 1' of the base wall from downward. The upper part of the base wall can be adhered to the upper part of the inner periphery 5 of the hollow and its lower part 1' can be adhered to the upper surface of the step shaped projecting part 13 by the both face adhering tape 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-shaped fastener for molding an adhesive window which is fitted and fixed in a recess formed in a vehicle body such as a windshield or a rear glass of an automobile.

[0002]

2. Description of the Related Art A belt-shaped fastener for molding an adhesive window is known from Japanese Utility Model Laid-Open No. 63-24014, and as shown in FIG. 4, a base wall 1 and a folded-back member which is folded upward from the lower end of the base wall 1. A J-shaped cross section having a wall 2 is formed by extrusion molding with plastic, and the base wall 1 is adhered with a double-sided adhesive tape 6 along the inner circumference 5 of a recess 4 which is slightly larger than the window glass provided in the vehicle body, and the recess is formed. The cross-sectional shape made of a rubber material for suppressing the edge of the window glass 9 whose peripheral edge is adhered with the sealant 8 on the edge of the window opening 7 opened at the bottom 4'of the T-shaped, inverted L-shaped, A downward leg 11 of a long molding 10 having a π shape or the like is held in a holding groove 3 formed between the base wall 1 and the folded wall 2. As a result, the decorative portion 12 exposed on the surface of the vehicle body of the molding 10 extends over the edge portion of the recess 4 on the vehicle body surface and the upper surface of the peripheral edge portion of the window glass 9, and seals rainwater or the like that tries to enter the inside of the recess. In addition, in order to prevent the downward leg 11 from slipping upward from the holding groove 3, a serrated locking claw 2'is provided on the upper end of the folding leg 2,
The downward leg 11 is provided with teeth 11 'that mesh with the locking claws 2'in multiple stages in the vertical direction.

[0003]

As shown in FIG. 5, one step, a staircase, is provided between the surface of the vehicle body and the bottom 4'of the recess at each of the left and right upper ends of the inner circumference 5 of the recess. There is a protrusion 13 in the shape of a circle. Since it is not possible to attach the downward leg of the molding at the portion where the protrusion 13 is present, conventionally, the protrusion 1 is formed by press working.
The lower end of the base wall 1 where the 3 is located, and the folded wall 2
While cutting out the base wall 1, a cut is formed in the lower part of the base wall 1 from below, and the lower part 1'of the base wall is heated and bent manually at a substantially right angle, and the bent lower part 1'is stepped as shown in FIG. It is adhered to the upper surface of the protrusion 13 with a double-sided adhesive tape. But,
Since the thickness of the base wall 1 is 0.7 to 1.0 mm, it takes a lot of time and time to bend the base wall 1 at a right angle, which causes a cost increase.

[0004]

According to the present invention, a lower portion 1'of a base wall can be easily bent at a substantially right angle so as to be aligned with an upper surface of a stepped protrusion 13 and is bonded to a vehicle body. An automobile window extruded from plastic with a J-shaped cross section having a base wall and a folded wall that is folded upward from the lower end of the base wall and forms a holding groove for holding the leg of the molding between the base wall and the base wall. The band-shaped fastener for molding of the present invention is characterized in that a weakened portion that is easily bent is provided in the longitudinal direction on the base wall.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The strip fastener of the embodiment shown in FIG. 1 is formed with a notch or a thin groove portion 15 in the longitudinal direction as a weakened portion 14 on the surface of the base wall 1 which is adhered to the inner periphery of the recess by a double-sided adhesive tape during extrusion molding. There is. Therefore, the lower end of the base wall 1 at the portion where the stepped protrusion 13 is located by press working and the folded wall 2 are cut off, and a notch 16 whose upper end reaches the notch 15 is provided on the lower portion 1'of the base wall. By forming from the notch 15, the lower part 1'of the base wall can be easily bent at a right angle as shown in FIG. 6, and the double-sided adhesive tape 6 allows the upper part of the base wall to cover the inner circumference 5 of the recess. The upper part and the lower part 1 ′ can be adhered to the upper surface of the stepped protrusion 13. Even if the longitudinal notch 15 is formed in the base wall 1 in this manner, the entire surface of the portion of the base wall 1 not located on the stepped protrusion 13 is bonded to the inner periphery 5 of the recess with the double-sided adhesive tape 6. Since it is fixed, there is no loss of function such as a decrease in strength.

In the embodiment shown in FIGS. 2 and 3, the lower end portion of the base wall 1 and the folded wall 2 located at the stepped protrusion 13 are cut off by pressing and the lower portion 1'of the base wall is cut down. When the cut line 16 is formed, the elongated hole 17 is opened in the longitudinal direction to form the weakened portion 14. The hole 17 may be a plurality of dotted lines other than the continuous one shown in the figure. Therefore, the lower part 1'of the base wall can be easily bent at a right angle with the hole 17 as a boundary. As shown in FIG. ′ Can be glued to the upper surface of the step projection.

[0007]

As is apparent from the above, the strip fastener for molding of the present invention has the step of projecting the lower portion of the base wall even if there is a stepped protrusion on the inner circumference of the recess to which the base wall is to be adhered with the double-sided adhesive tape. Can be easily bent at a right angle and adhered to the upper surface of the protrusion. Therefore, the time required for heating and bending the lower portion of the base wall in the related art can be saved, the number of steps can be reduced, and the molding bending step can be significantly shortened.
