Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved weatherstrip having a U-shaped opening trim and a hollow seal for mounting on an automobile body opening edge flange.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, a weather strip 6 having a hollow seal portion 8 integrated with a U-shaped opening trim 7 to be attached to a flange 1a of a body opening edge 1 of a conventional automobile is provided. It is used. The weather strip 6 has a plurality of small claws 7b on one surface and a large claw 7 near the entrance of the other surface of the opposing inner surfaces of the U-shaped opening trim 7 in which the core metal 7a is embedded.
c is protruded so as to be inclined inward.
The large claw 7c and the large claw 7c sandwich the flange 1a.

[0003] However, the thickness of the large claw 7c of this weather strip is designed to be easy to insert into the flange 1a having a large thickness so that the thickness can be adjusted from a large thickness to a small thickness. However, when the opening trim 7 is removed as shown in FIG. 6, there is a problem that the large claw 7c warps toward the entrance side and the clamping force on the flange 1a is weakened.

[0004]

[Problems to be solved by the invention] The problem to be solved is that if the thickness of the large claw is reduced in order to facilitate the insertion of the opening trim into the flange having a large plate thickness, when the opening trim is removed, The large claws warp to the inlet side, and the holding force on the flange 1a is weakened.

[0005]

The present invention will be described with reference to FIGS. The present invention includes a hollow seal portion 5 integrated with a U-shaped opening trim 4 in which a metal core 4a to be attached to a flange 1a of a front edge 1 of a vehicle body is embedded.
A plurality of small claws 4b are provided on one of the opposing inner surfaces of the U-shaped opening trim 4 and a large claw 4c is protruded inwardly in the vicinity of the other entrance.
b and the large claw 4c to sandwich the flange 1a. In particular, the thickness of the base portion of the large claw 4c is made smaller than the tip, and the large claw 4c is formed.
On the inner surface of the opening trim 4 closer to the entrance side than c, a large claw warpage prevention protrusion 4d is provided.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. 1 to 4. Reference numeral 1 denotes a body opening edge of an automobile; 1a, a flange protruding along the body opening edge;
a weather strip attached to a U-shaped opening trim 4 having a cored bar 4a embedded therein and a hollow seal portion 5 integral therewith, and of the opposing inner surfaces of the U-shaped opening trim 4 A plurality of small claws 4b are provided on one side (the side to which the hollow seal portion 5 is connected), and a large claw 4c is protruded inwardly in the vicinity of the other entrance. The thickness of the base of the large claw 4c is smaller than that of the tip, and a large claw warpage prevention projection 4d is provided on the inner surface of the opening trim 4 on the entrance side of the large claw 4c. 2 is a door.

To explain the operation, the large claw 4c is easy to bend, and when this weather strip 3 is mounted on the flange 1a, the insertion resistance of the U-shaped opening trim 4 into the flange 1a is reduced even if the thickness of the flange 1a is large. Less and easy to insert. On the other hand, at the time of removal, even if the large claw 4c is dragged by the flange 1a and tries to warp toward the inlet side, the large claw 4c does not warp because it is received by the large claw warp prevention projection 4d. Sufficient holding force is maintained.

[0008]

[Effect of the Invention] Since the present invention is configured as described above,
It is possible to prevent the large claw 4c from warping toward the entrance side, and to always secure a sufficient clamping force of the flange 1a.
