Abstract

PROBLEM TO BE SOLVED: To join a lateral end of a weather strip to a glass run without producing a clearance therebetween while accommodating variations in processing or assembling accuracy of the weather strip and the glass run. SOLUTION: A laterally extending frame-like weather strip 21 slidably contacts a midsection of a door glass 9 of a vehicle. The weather strip 21 comprises a window frame inserting portion 24 that is inserted into the inside of a lower edge (flange 4a) of a door window opening. A relatively soft and deformable sponge-like sealing material 29 having elasticity and water-resistance is secured to a lower portion of a lateral end of the window frame inserting portion 24. A vertically extending frame-like glass run slidably contacts lateral ends of the door glass 9. The glass run is fixed to a lateral edge portion of the door window opening. The weather strip 21 is fixed to the lower edge portion of the door window opening. At the same time, the sealing material 29 is deformed by contact with a window frame fitting portion 16D of a glass run joint 14 so as to closely contact the window frame fitting portion 16D. Thus, the lateral ends of the weather strip 21 are joined to the glass run.

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vertically long frame-shaped glass run fixed to a lateral edge of a window opening of an automobile door.
The present invention relates to a weather strip end joining structure in which a horizontally long frame-shaped weather strip is fixed to a lower edge of a window opening, and a lateral end of the weather strip is joined to a glass run.

[0002]

2. Description of the Related Art FIG. 9 is a side view (a), a plan view (b) and an end view (c) of a weather strip to which a conventional weather strip end joining structure is applied.
FIG. 10 is an enlarged cross-sectional view of a joining portion between a lateral end of the weather strip of FIG. 9 and a glass run.

[0003] The upper edge and both lateral edges of the window opening of the side door of the automobile have a generally U-shaped downwardly open U-shape comprising a horizontally long upper frame portion and a vertically straight horizontal frame portion. A frame-shaped glass run is fixed, and a horizontally long frame-shaped weather strip is fixed to the lower edge of the window opening, and the lateral end of the weather strip is in contact with the glass run. Are joined. That is, as shown in FIGS. 9 and 10, in the weather strip 21, a joining notch 27 formed by cutting off the upper portion of the lateral end of the window frame insertion portion 24 is provided in the window frame fitting portion 16 _D of the joining portion 14 of the glass run. It is provided corresponding to the shape. The weather strip 21, and the side edge lower part of the window frame insertion portion 24 so as to abut against the inner bottom of the window frame fitting portion 16 _D of the glass run, it is bonded to the glass run.

[0004]

As described above, the lateral end of the weather strip 21 is connected to the glass run (connection portion 14).
When it is brought into contact with and joined, the processing accuracy of the weather strip 21 or the glass run, the variation of the assembly accuracy, etc.
A gap may be formed at the joint between the weather strip 21 and the glass run, and this causes a problem that the sound insulation is deteriorated and rainwater or draft is invaded. In the case of the weather strip 21 in which the core metal 26 is sealed,
There is a problem that the core metal 26 is exposed from the joining notch 27, and rust is easily generated from the exposed portion of the core metal 26.

In view of the above problems, the present invention absorbs variations in processing accuracy and assembly accuracy of a weather strip or a glass run, and joins the lateral end of the weather strip to the glass run without leaving a gap. Can also
It is an object of the present invention to provide a weather strip end joining structure capable of preventing rust of a metal core in the case of a weather strip in which a metal core is sealed.

[0006]

According to a first aspect of the present invention, a vertically long frame-shaped glass run slidably abutting against a lateral edge portion of a door glass of an automobile is provided with an opening for a window of an automobile door. A horizontally long frame-shaped weather strip fixed to the side edge and slidably in contact with the center of the door glass is fixed to the lower edge of the window opening, and the horizontal end of the weather strip is connected to the glass run. In a weather strip end joining structure to be joined, a sealing material that is soft and deformable as compared with a glass run is fixed to a lateral end of the weather strip,
The sealing material is configured so as to be deformed by contact with the glass run and adhere to the glass run.

Further, in the invention according to claim 2,
The weatherstrip is provided with a window frame insertion portion inserted inside the lower edge of the window opening, and the sealing material is fixed to a lower portion of the window frame insertion portion. In the third aspect of the invention, the sealing material is made of a sponge-like material having elasticity and waterproofness.
Further, in the invention described in claim 4, a core is sealed inside the weather strip, and the sealing material is fixed so as to cover an exposed portion of the core.

According to the first aspect of the present invention, the deformation of the sealing material absorbs a processing error of the weather strip or the glass run, a variation at the time of assembling, and the like, so that the lateral end portion of the weather strip does not leave a gap. Therefore, it is possible to improve sound insulation and to prevent rainwater or draft from entering.

According to the second aspect of the present invention, since the sealing material is arranged at a position where it is difficult to visually recognize the sealing material from the outside, there is no problem in appearance. Further, according to the third aspect of the present invention, the sealing material can be securely adhered to the glass run. According to the fourth aspect of the invention, it is possible to prevent rust from being formed on the core metal of the weather strip from the exposed portion.
