Description

[Detailed Description of the Invention] This invention relates to an improvement of a weather strip that is attached to the opening side edge of an opening/closing part of an automobile body.

FIG. 5 is a diagram showing a state in which a conventional weather strip 21 is attached to a bent opening side edge 22 of an opening/closing portion of a vehicle body. In the figure, the weather strip 21
A sealing tongue without a core bar is provided diagonally at the lower end of one side part 24a of a band-shaped clamping part 24 which has an inverted U-shaped cross section and has a core bar 23 embedded therein, which clamps a bent opening side edge 22 of the belt. The piece 25 is warped too much in the bending direction of the side edge 22 and does not come into close contact with the vehicle body panel 22a, and rainwater enters into the perforation as shown by the arrow, wind pressure etc. increase, reducing air and water tightness by half, and causing dirt. It is the cause of
As a measure to prevent this, there is a method of integrally molding and adhering the curved weatherstrip portion corresponding to the curved side edge 22 to the straight weatherstrip portion, but this method is cumbersome and time consuming, and increases cost. In the figure, 26 is a window glass, 27 is a window glass seal part,
28 is a clamping tongue piece.

This invention was devised in view of the above-mentioned drawbacks, and its purpose is to provide a weather strip that ensures air and water tightness of the curved opening side edge portion of the vehicle body opening/closing part.

The gist of this invention consists of a band-shaped clamping part made of solid rubber with an inverted U-shaped cross section and clamping tongues arranged on the inside of both sides, which clamps the opening side edge of the opening/closing part of the vehicle body, and a lower end of one side of the clamping part. A series of cored metals are bendably embedded inside the inclined part and the clamping part, and the lower end of the inclined part is made of the same material and made of sponge rubber and comes into elastic contact with the vehicle body panel. A downward sealing tongue is provided vertically, and a hollow sealing wall is extended from the base of the tongue, and the end of the extending wall is integrally fixed to the main part of the side of the side part, and is connected to the window glass of the opening/closing part. It is characterized by having an elastic hollow seal part.

Hereinafter, embodiments of this invention will be described in detail with reference to illustrative diagrams in FIGS. 1 to 4.

Figure 1 is a sectional view of this invention. Figure 2 is a scale development of the core metal. FIG. 3 is an explanatory diagram of the mounting location of this invention. FIG. 4 is a diagram of the installed state.

In the figure, reference numeral 1 denotes a weather strip of this invention, which is attached to an opening side edge 2a of an opening/closing part 3 of a car body 2. 4 is a band-shaped holding part made of solid rubber, with an inverted U cross section.
The side edges 2a are formed inside the both sides 4a.
Clamping tongues 4b for clamping are provided oppositely. In this invention, a side portion 4 is attached to the lower end of the side portion 4a on one side of the clamping portion 4.
An inclined part 4c (same material as the clamping part) which is inclined outward (toward the opening/closing part window glass side) by approximately 45 degrees from a is extended, and the inclined part 4 is
A series of core metals 5 are bendably buried inside the sloping portion 4c and the body panel 2 at the lower end of the sloping portion 4c.
A downward sealing tongue 4d made of the same material as above and made of sponge rubber is vertically provided, and the tongue 4d is in elastic contact with b.
d A hollow seal part 6 is formed by extending a hollow seal part wall 6a from the base, and integrally fixing the end 6b of the extension wall to the main part of the side surface of the side part 4a, so as to make elastic contact with the window glass 7 of the opening/closing part 3. This is the configuration provided. The core bar 5 is integrally connected by a connecting portion 5b that bends and breaks the parallel pieces 5a, and when buried, the connecting portion 5b is located within the clamping portion 4. The shape of the hollow seal portion 6 is not particularly limited.

FIG. 4 is a diagram showing how this invention is installed, showing a cross section when it is installed on the opening side edge 2a of the bent part (inside the circle line) of the opening/closing part 3 of the automobile body 2 in FIG. ,
An inclined part 4 that is bent to follow the bent side edge 2a (radius of about 30 mm) without any difficulty and has a core bar 5 integrated therewith.
Seal tongue piece 4d c warps slightly against the core metal 5, but does not warp any more and is in elastic contact with the vehicle body panel 2b.
There is no change in the elastic contact force, ensuring air and water tightness. Note that the hollow seal portion 6 that is in air-tight and elastic contact with the window glass 7 is not deformed or buckled, and there is no change in air-tightness or water-tightness with the window glass 6.

According to this invention, the disadvantages of conventional weather strips, such as air, watertightness and staining, can be solved, and the use of the weather strip is of great value. The present invention is economical because it does not require molding and adhesion as in the past.

Claims (1)

[Scope of utility model registration request] A band-shaped gripping part made of solid rubber that has an inverted U-shaped cross section and has gripping tongues on the inside of both sides, which grips the opening side edge of the vehicle body opening/closing part, and a slope that slopes outward at the lower end of one side of the gripping part. A series of core metals are bendably buried inside the inclined part and the clamping part, and a downward sealing tongue made of the same material as the above and made of sponge rubber is provided at the lower end of the inclined part to make elastic contact with the vehicle body panel. At the same time, the hollow seal part wall is extended from the base of the tongue piece, and the end of the extended wall is integrally fixed to the main part of the side surface of the side part, so that the hollow seal part makes elastic contact with the window glass of the opening/closing part. A weather strip is provided.
