Description

[Detailed description of the invention] (Field of industrial application) The present invention is designed to be installed between a windshield and a window frame of a car body, etc., so that rainwater, etc. This invention relates to a weather strip for windows that blocks water from entering.

(Prior Art) Conventionally, this type of weather strip for automobiles has been devised, for example, as shown in Publication No. 59714/1983.

That is, in FIGS. 3 and 4, A is the outer panel of the body of the automobile, and B is the outer panel of the body A.
, C is the outer surface of the body outer panel A, and D is the window glass.

E is a weather strip made of elastic material.
This weather strip E has a first groove F into which the lower part of the window glass D is inserted, a second groove G into which the flange B is inserted, and an outer surface that comes into contact with the outer surface C of the body outer panel A. A contact portion H and a tongue portion I are formed.

J is a lower end surface abutting portion with which the lower end surface of the window glass D abuts, and K is an inner abutting portion with which the inner surface of the window glass D abuts.

A hollow portion M is formed in the outer surface contact portion H, the lower end surface contact portion J, and the inner surface contact portion K, with the thin outer layer L remaining.

(Operation of the prior art) The flange B of the body outer panel A is inserted into the second groove G of the weather strip E, and the outer surface abutting portion H and the tongue portion I of the weather strip E are It is brought into contact with the outer surface C of the body outer plate portion A. Also,
The lower part of the window glass D is inserted into the first groove F of the weather strip E, and its lower end surface is brought into contact with the lower end surface contacting part J, and the inner surface of the window glass D is brought into contact with the inner surface contacting part K. Let them come into contact with you.

As a result, the lower end surface contact portion J, outer surface contact portion H, and tongue portion I are pressed by the own weight of the window glass D, and the inner contact portion K is pressed against the window glass D.
is crimped to the inner surface of the Therefore, each hollow part M is crushed, and the outer layer L closely contacts the corresponding position of the window glass D, thereby blocking rainwater and the like from entering the interior of the vehicle.

(Problems to be Solved by the Invention) However, in the conventional weather strip E, since the cross-sectional shape of the hollow part M is elliptical, it is simply crushed when the window glass D is attached. Therefore, only the pressure force of the outer layer L acted on the window glass D, and its airtight effect was not effective.

(Means for Solving the Problems) The present invention was devised to solve the above-mentioned conventional drawbacks, and its gist is that the seal part that clamps the edge of the window glass, and the window frame. A fixing part that clamps the flange part of the glass is integrally formed with an elastic material, and a hollow part with a pentagonal cross section is formed at the end contact part of the glass through an easily deformable outer part, and the top of the hollow part is It is characterized in that the corners correspond to the outer shell.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

(Structure of the Embodiment) FIG. 1 is a longitudinal cross-sectional view of a weather strip for an automobile or the like according to the present invention, and FIG. 2 is a longitudinal cross-sectional view of the same weather strip structure in use.

In the drawings, 1 is the body of an automobile, a nearly vertical flange 2 is formed at the lower edge of a window frame formed on the body 1, 3 is the outer surface of the body 1, and 4 is the above-mentioned flange. A window glass that is attached to a window frame.

5 is a weather strip made of synthetic resin, etc., and this weather strip 5 is attached to the seal portion 6.
and a fixing part 7 formed on the side of this seal part 6.
and two long and short tongue-like parts 8 and 9 hanging down from the lower part of the seal part 6.

A receiving groove 10 that opens upward is formed in the seal portion 6 in order to insert and clamp the lower part of the window glass 4, and in this receiving groove 10,
Contact portion 11 that the lower end surface of the window glass 4 contacts
is formed. A hollow portion 13 is formed in this contact portion 11 through an outer portion 12 having a thickness that allows it to easily deform downward under the weight of the window glass 4 .

This cavity 13 has a pentagonal cross-sectional view;
The apex portion 13a corresponds to the outer shell portion 12. The seal portion 6 clamps the lower portion of the window glass 4 from the left and right sides due to its elastic force.

Further, in order to insert and clamp the flange part 2 of the body outer plate part 1, the fixing part 7 is formed with an insertion part 14 that opens downward, and clamps the flange part 2 by elastic force.

(Operation of the embodiment) Therefore, the flange portion 2 of the body 1 is inserted into the insertion portion 14 of the weather strip 5, and the tongue-shaped portions 8 and 9 are elastically attached to the outer surface 3 of the body 1. Deform and stick together. Further, the lower part of the window glass 4 is inserted into the receiving groove 10 of the seal part 6, and its lower end surface is brought into contact with the contact part 11, so that the lower part of the window glass 4 is clamped and supported by elastic force.

As a result, the outer shell 12 of the abutment part 11 is pressed by the weight of the window glass 4, and the force descends toward the first apex corner 13a of the hollow part 13, and is dispersed laterally. It is added to the apex portion 13b. In the left and right apex portions 13b, an upward component force is generated, and an inward force is applied to the seal portion 6, so that combined with the clamping force of the seal portion 6 itself, the windshield 4 The clamping force against the side of the frame increases.

Therefore, water such as rainwater from entering the vehicle interior from between the window glass 4 and the seal portion 6 is reliably blocked.

In addition, although the above-mentioned example explained the window frame of a car, it is not limited to this and can of course be applied to household window frames and other window frames.

(Effect of the invention) As described above, the present invention has a seal part 6 that clamps the edge of the window glass 4, and a flange part 2 of the window frame.
A contact part 1 is formed integrally with a fixing part 7 made of an elastic material, and the end surface of the window glass 4 comes into contact with the fixing part 7.
1, a hollow part 13 having a pentagonal cross section is formed through an easily deformable outer part 12, and this hollow part 1
3 corresponds to the outer shell part 12, the hollow part 13 is elastically deformed by the weight of the window glass 4, and the generated force is added to the seal part 6. , window glass 4
This increases the clamping force against the vehicle interior, making it possible to reliably prevent rainwater and the like from entering the vehicle interior.
