Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is used in the technical field of doors in vehicles, and particularly relates to a seal structure for automobile doors.

(Prior Art) A door device (see, for example, Japanese Utility Model Application Laid-Open No. 59-58626) is known in which a triangular corner bracket is provided at the lower front side of a door sash provided above a door panel of an automobile. On the other hand, a door device (see US Pat. No. 4,240,227) is also known in which a door glass is provided outside the vehicle body of the door sash to form a flash surface.

(Problem to be Solved by the Invention) However, when the door device equipped with the above-mentioned triangular corner bracket is used as a flash surface, the weather strip that contacts and seals the end face of the door glass and the outer surface of the vehicle body must be attached to the entire flange of the door frame. Even if the weatherstrip is provided on the periphery of the door, the weatherstrip does not come into contact with the end surface of the door glass in the triangular corner portion that is not covered by the door glass, so the sealing performance between the weatherstrip and the door sash deteriorates, and the weatherstrip does not come into contact with the vehicle body. A problem arises in that the sealing pressure against the outer surface is reduced and the sealing performance in this area is also incomplete. In addition, the above-mentioned Jitsukasho is equipped with a triangular corner bracket.
The door of US Pat. No. 59-58626 is not formed with a flat surface surface, while the door of US Pat. No. 4,240,227 is formed with a triangular corner bracket, but the seal is incomplete at that point. This cannot meet the above-mentioned desire to eliminate the problem.

In view of the above-mentioned problems, the present invention provides a flat surface type automobile door in which a triangular corner bracket is provided at the lower front side of the doorway.
An object of the present invention is to provide a sealing structure for an automobile door in which the sealing action of a weather strip at a triangular corner bracket portion is perfected.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention is to provide an automobile door in which the door glass is located outside the vehicle body and is raised and lowered by the door sash provided above the door panel. Assumed. A flat part formed approximately parallel to the door glass and having a flange on the outer periphery is provided on the outside of the vehicle of the door sash, and the entire periphery of the outer periphery flange of the flat part is in contact with the end face of the door glass for sealing. A weather strip is provided which has a glass abutting surface and a lip which abuts and seals against the outer surface of the vehicle body around the door sash when the door is closed. A triangular corner bracket is provided at a triangular corner portion formed at the lower front side of the door sash, and a rear sash is formed at the rear end of the triangular corner bracket, and the rear sash guides the front end of the door glass in a vertically movable manner. ing. A seal bracket is provided on the flat surface of the door sash where the triangular corner bracket is located, and is formed to have the same shape and dimensions as the end surface of the door glass and comes into contact with the glass contacting surface of the weather strip.

(Function) As a result, the glass contacting surface of the weather strip provided all around the outer periphery flange of the flat part of the door sash comes into contact with the end surface of the door glass and is sealed, and the lip of the weather strip contacts the outer surface of the vehicle body around the outer periphery of the door sash when the door is closed. Since it comes into contact with and seals, it prevents rain from blowing in. and,
In the triangular corner bracket, the seal bracket provided on the flat surface of the door sash comes into contact with the weather strip in this area, improving the sealing performance between the weather strip and the door sash, and the seal bracket also prevents the door from closing when the door is closed. The sealing pressure of the lip of the weather strip against the outer surface of the vehicle body is increased, and the sealing performance of this area is also improved. Thus, the weatherstrip provides a tight seal over its entire length.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 3, the door 1 of this embodiment has a door sash 3 provided above the door panel 2, a door glass 4 located outside the vehicle body of the door sash 3 (see FIG. 4), and is configured to be movable up and down. ing.
Further, on the outside of the vehicle body of the door sash 3, a flange 3b is provided on the outer periphery formed approximately parallel to the door glass 4.
A flat portion 3a having a diameter is provided. A weather strip 5 having a glass abutting surface 5a that comes into contact with the end surface 4a of the door glass 4 for sealing is fitted around the entire circumference of the outer peripheral flange 3b of the flat portion 3a. On the other hand, a triangular corner portion 3c is formed at the lower front side of the door sash 3, and a triangular corner bracket 3d is provided on this triangular corner portion 3c. Also, this triangular corner bracket 3d
The front end portion 4b of the door glass 4 is guided so as to be movable up and down by the rear side sash 3e. A seal bracket 6 is provided on the flat part 3a of the door sash 3, which can be placed at the location where the triangular corner bracket 3d is located, and its tip edge 6a abuts against the glass abutting surface 5a of the weather strip 5 to seal this part. are doing. Note that the tip edge 6a is formed to have the same shape and dimensions as the end surface 4a of the door glass 4.

There is a lip 5 on the outer periphery of the weather strip 5.
b are integrally arranged, and seal between the outer periphery of the door sash 3 and the outer surface 7a of the vehicle body 7 when the door is closed. Further, a door seal portion 5c is integrally provided on the outer peripheral edge of the weather strip 5 and inside the lip 5b, so that when the door is closed, the door seal portion 5c is connected to the outer periphery of the door sash 3 and the stepped portion 7b of the vehicle body 7. Configured to provide a seal.

The rear side 3g of the door sash 3 is parallel to the rear sash 3e of the triangular corner bracket 3d. On the other hand, a glass guide 8 is fixed to the door glass 4 at a predetermined location inside thereof (in this embodiment, one location at the front and two locations above and below at the rear), and the front glass guide 8 is attached to the rear sash 3e. The door glass 4 is configured to be able to slide up and down by slidingly contacting the rear guide 8 along the sealing member 9 fitted to the inner circumferential flange 3f of the rear side 3g of the door frame. ing.

Next, the operation of this embodiment will be described.

In FIG. 4, the door glass 4 slides up and down along the inner peripheral flange 3f of the door sash 3 and the rear sash 3e parallel to this, and its end surface 4a is sealed by the glass contact surface 5a of the weather strip 5. Ru. On the other hand, as shown in FIG.
are in contact with each other and the weather strip 5 and door sash 3
The glass contact surface 5 of the tip edge 6a of the seal bracket 6 is improved.
Due to the contact with a, the sealing pressure of the weather strip 5, especially the lip 5b, against the outer surface 7a of the vehicle body increases when the door is closed, thereby improving the sealing performance of this portion. The weather strip 5 is thus completely sealed around its entire circumference.

(Effects of the invention) With the above configuration, the present invention provides a seal bracket that contacts the weather strip in the triangular corner bracket, so it has a triangular corner portion.
In addition, in a flash surface type automobile door, the triangular corner portion of the weather strip has the effect of completely sealing the door sash and the outer surface of the vehicle body.
