Abstract

PROBLEM TO BE SOLVED: To provide a weather strip with a stud insertion fitting by which the inflow of molten rubber due to dislocation between engaging pieces can be securely prevented, and the impairment in the assemblage with a stud is previously prevented, and the process for removing the inflow rubber can be dispensed with for enhancing the productivity. SOLUTION: A pair of engaging pieces 22, 22 are erected on a base plate 21 so as to be parallel in the longitudinal direction, and a front wall 23 and a rear wall 24 are erected to the front end part and the rear end part of both engaging pieces 22, 22 respectively, and the tops of the front wall 23 and the rear wall 24 are flush with the tops of both engaging pieces 22, 22. The outside surfaces of the front wall 23 and the rear wall 24 are set vertical surfaces, so that both the engaging pieces 22, 22 and the front wall 23 and the rear wall 24 form nearly a box shape.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip in which a stud insertion fitting provided on the back surface of the weather strip is embedded for mounting the weather strip on a door sash or a body of an automobile.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS.
As a means for assembling the weather strip 10 to the door sash 40 of the automobile, for example, a stud 30 is provided on the sash A of the center pillar portion, and the stud insertion fixture 20 is embedded on the back surface of the weather strip 10,
By pressing the stud 30 into the fixture 20, the weatherstrip 1 is inserted into the sash A of the center pillar portion.
In some cases, 0 is attached.

[0003] The structure of the stud insertion fitting of the weather strip 10 is usually such that after the fitting 20 into which the stud 30 is press-fitted is arranged in the mold 50, the molten rubber G is poured into the mold 50 and attached. The tool 20 is formed by embedding and integrating the tool 20 into the rubber weather strip 10.

Conventionally, the structure of the mounting device 20 is such that the height of the front wall 23 and the rear wall 24 is set lower than the height of the engaging pieces 22, 22 which engage with the stud 30, and the upper end surface thereof is Since the lower ends of the upper inclined surfaces of the two engagement pieces 22 are connected to each other, the vertical cross-sectional shape is substantially a saucer shape (FIG. 3). The front end surface and the rear end surface of each engagement piece 22 are respectively inclined surfaces (FIG. 2).

In this conventional mounting device 20, the vertical cross-section formed by the front wall 23, the rear wall 24, and the two engaging pieces 22, 22 is substantially pan-shaped, and each of the engaging pieces 22,2
Since the front end face and the rear end face of No. 2 are inclined surfaces, and their shapes are slightly complicated, it is difficult to always perform accurate positioning with the mold 50.

As a result, the mounting fixture 20 and the mold 50 are misaligned, and the misaligned front wall 23 and rear wall 2 are displaced.
A problem occurs in that the molten rubber G flows between the two engagement pieces 22 from the four portions (arrows in FIG. 4), and the stud 30
And the assembling piece with the engaging piece are deteriorated. Further, if the rubber flowing into the two engaging pieces 22, 22 is to be removed in order to prevent deterioration of the assembling property, a step for that is required, and the productivity is reduced.

[0007]

The problem to be solved is that, in the above-described conventional mounting tool 20, the mold 5
Since it is difficult to accurately position the stud 30 with the molten rubber G, the molten rubber G flows between the two engagement pieces 22 of the fixture 20, and the assembling property with the stud 30 is deteriorated, and the productivity is reduced. That is.

[0008]

Means for Solving the Problems FIGS. 1, 5 and 6
This will be described with reference to FIG. According to the present invention, a pair of engaging pieces 22 and 22
A stud insertion fixture 20 for a weatherstrip 10 having a front wall 23 and a rear wall 24 erected at front and rear ends of both engagement pieces 22, 22, respectively. The rear wall 24 and the two engaging pieces 22
And the outer surfaces of the front wall 23 and the rear wall 24 are vertical surfaces.
And the front wall 23 and the rear wall 24 form a substantially box shape.

[0009]

Embodiments of the present invention will be described. A in the figure shows a sash A of a center pillar portion of an automobile to which a weather strip 10 in which a stud insertion fixture 20 of the present invention is embedded is attached. This fixture 2
0, a pair of engaging pieces 22, 22 are erected on the substrate 21 in parallel in the front-rear direction, and a front wall 23 and a rear wall 24 are respectively provided at the front end and the rear end of the two engaging pieces 22, 22. It is configured by standing up. The front wall 23 and the rear wall 24 are set at the same height as the tops of the engagement pieces 22, 22, and the outer surfaces of the front wall 23 and the rear wall 24 are set to be vertical surfaces. The engagement pieces 22, 22, the front wall 23, and the rear wall 24 form a substantially box shape.

In operation, the weatherstrip provided with the stud insertion fitting 20 of the present invention has a front wall 23 and a rear wall 24 whose height is the same as the height of the tops of the engagement pieces 22 and 22. With the outer surfaces of the front wall 23 and the rear wall 24 as vertical surfaces, the two engaging pieces 22, 22, the front wall 23, and the rear wall 24 form a substantially box shape. Since the simple shape including the horizontal surface and the vertical surface without the inclined surface except for the upper end surface is used, the mold 50 can also be a simple shape with a small inclined surface.

Since the positioning of the simple mounting fixture 20 and the simple molding die can be easily and accurately performed, the molten rubber G is displaced by the displacement of the mounting fixture 20 and the die. , 22 does not occur.

Further, in this embodiment, only the case of attaching to the stud of the door sash has been described, but the present invention is also applicable to the case of attaching to the stud of the body.

[0013]

According to the mounting device 20 of the present invention, the pair of engaging pieces 22, 22, the front wall 23, and the rear wall 24 form a substantially box shape and have a simple shape. The positioning with the mold which can be made into a simple shape can be accurately performed, so that the molten rubber G can be reliably prevented from flowing into the space between the two engagement pieces 22 due to the displacement, and the stud can be formed. In addition, it is possible to prevent the deterioration of the assembling property beforehand, and to improve the productivity by eliminating the step of removing the flowing rubber.
