Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a door weatherstrip around a door frame of an automobile door.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5, conventionally, a door weather strip 10 is fixed to an outer periphery 2a of a door frame 2 of an automobile via a retainer 11, and when the door is closed, the door weather strip 10 is closed. The hollow seal portion 10b is elastically contacted with the door opening edge 4 of the vehicle body.

[0003]

However, in the above-mentioned conventional mounting structure of the door weather strip 10, the water W penetrating from the outside of the vehicle as shown by an arrow is located between the edge 2c of the door frame 2 and the door weather strip 10. It was easy to accumulate, causing problems such as rust. In view of the above, it is an object of the present invention to provide a door weather strip mounting structure in which water entering the door frame is effectively drained to prevent rust and the like.

[0004]

In order to achieve the above object, according to the present invention, a base 1a of a door weather strip 1 is fixed to an outer peripheral edge 2a of a door frame 2 as shown in FIGS. The outer peripheral edge 2
a, a drain groove 5 is recessed along the outer edge of the vehicle, and the mounting surface 2b on the inner side of the outer peripheral edge 2a and the base 1a are fixed by the clip 3, and the mounting surface on the outer side of the clip 3 2b, a mounting structure of the door weather strip, wherein the mounting surface 2b and the base 1a of the door weather strip 1 are sealed by interposing a highly foamed sponge layer or a double-sided tape 8 therebetween. This is a door weather strip mounting structure in which the curvature of the corner 9 at the boundary between the drain groove 5 on the outer peripheral edge 2a and the mounting surface 2b is made as small as possible.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a door weather strip of a roof portion of the automobile shown in FIG. 4, in which a base 1a is fixed to a flat mounting surface 2b of an outer peripheral edge 2a of a door frame 2 by a clip 3, and a hollow seal portion 1b when the door is closed. Is elastically contacted with the door opening edge 4 of the vehicle body.

A drain groove 5 is formed in the outer peripheral edge 2a of the door frame 2 along the outer edge of the vehicle. Therefore, even when rainwater or the like W enters from between the outside edge of the door frame 2 and the door weather strip 1 as shown by an arrow from the outside of the vehicle when the door is closed, the drainage groove 5 does not stay there.
After entering, it flows along the front-rear direction of the vehicle and is easily discharged out of the vehicle. The configuration of the outlet portion for discharging the rainwater or the like W is, for example, as shown in FIGS. 2 and 3A and 3B, at the corner portion of the door weather strip 1, the terminal portion 5a in which the drain groove 5 is cut off in the door frame 2. A wall 6 is provided on the door weather strip 1 so as to fill the recess on the rear side on the outside of the vehicle so as to be in contact with the edge 2c of the door frame 2, and a small lip 7a is provided on the front side of the wall 6. A notched drain port 7 is formed. In other words, rainwater and the like W
After spilling from the terminal portion 5a, it is blocked by the wall portion 6 and escapes from the drain port 7 to the outside of the vehicle.

As shown in FIG. 1, the base 1a and the mounting surface 2b are fixed by the clip 3 as described above. However, in order to prevent rainwater or the like W from entering the inside of the vehicle from the drain groove 5,
a and the mounting surface 2b are sealed with a highly foamed sponge layer or double-sided tape 8. In this case, it is desirable that the highly foamed sponge layer or the double-sided tape 8 be provided on the mounting surface 2b outside the clip 3 as shown in the drawing in order to facilitate the mounting of the clip 3. In addition, the sponge layer of high foaming is 0.1 to 0.3 of high foaming than the normal specific gravity of 0.4 to 0.7.
A degree of sponge layer may be adhered or molded integrally with the main body.

The drain groove 5 on the outer peripheral edge 2a and the mounting surface 2b
The radius of curvature of the corner 9 at the boundary between the two is made as small as possible, that is, is made to be an acute angle to prevent the infiltration water from easily overflowing to the mounting surface 2b side, so that the drainage efficiency by the drain groove 5 can be improved. .

[0009]

As described above, according to the door weather strip mounting structure of the present invention, the water entering the inside of the door frame is formed by forming the drain groove along the outer side edge of the outer periphery of the door frame. Can be effectively drained, so that it is possible to prevent water from accumulating inside the door frame and generate rust and the like as in the related art.
