JPS6198615A - Glass run structure for automobile door - Google Patents

Abstract

PURPOSE:To avoid water drops along the glass run from wetting the door lock, by furnishing a guide member, in the direction sloping rear-ward apart from the door lock, at the bottom of the glass run which is placed at the rear side of the window sash. CONSTITUTION:At the bottom 3a of the glass run 3, a rubber block 9 formed with the section same as the glass run 3 is used to fix a glass run cutting piece 8. The glass run cutting piece 8 is arranged to be sloped down apart from the door lock 7. And a down-sloping flow down surface is formed by an outer lip 8a and an inner lip 8b installed on the glass run cutting piece 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automobile door, and more particularly to a glass run structure that takes into account rust prevention of a door lock.

1. Prior Art As is well known, most of the water droplets adhering to the surface of the door glass 1 of a 1ζA for automobiles as shown in FIG. 4 flow down along the door glass 1. The water flowing down in the vicinity passes through the glass run 3 fitted to the rear side part 2a of the sash and enters the inside of the door panel 4. In addition, recently in automobile doors, in order to reduce the weight of the vehicle body or eliminate interference with the door lock 7, the rear part 2a of the sash is terminated near the outside handle 5 inside the door panel 4, as shown in the second figure. In accordance with this, the lower end of the glass run 3 is terminated in a state slightly protruding from the sash rear side part 2a, and the lower part of the door glass 1 when lowered is often supported by a damping member (not shown).

By the way, since the lower end 3a of the conventional glass run 3 has an end shape in which the glass run 3 is cut horizontally in the transverse direction, the water flowing down the glass run 3 into the door panel 4 is Irregular water drops drip from the horizontal lower end 6, but a door lock 7 is located near the sash rear side 2a, and the water droplets scattered from the lower end surface 6 of the crow run 3 hang on the door lock 7. For this reason, conventionally, the rotating parts of the door lock 7 are subjected to strict anti-rust treatment or grease is applied to the rotating parts, but
If raindrops etc. adhere to the door lock, electrolytic corrosion will occur and grease will flow out, so a sufficient rust prevention effect cannot be expected. Also, in cold regions, water on the door lock may freeze and cause the door to become damaged. There was a risk that the lock would malfunction.

・ -Object of the invention- In view of the malfunction of conventional door locks and the problem of anti-G-L as described below, the object of the invention is to prevent water droplets flowing down the crow run from hanging on the door lock. There is no such thing as getting a structure.

Structure of the Invention - To achieve this object, the present invention provides seals that fit into the sash and extend obliquely inward from both opening edges of the U-shaped cross section. In the crow run supporting the sash, it is proposed to provide a guide portion extending diagonally downward in a direction away from the door lock at the lower end of the crow run located on the rear side of the sash.

One Embodiment - Hereinafter, details of an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows the fifth embodiment of an automobile door showing the first embodiment of the present invention.
This is an enlarged view corresponding to the figure, and in the case of this embodiment, a glass run cut piece 8 is used as a guide part. That is, a cut piece 8 of the glass run 3 is attached to the lower end 3a of the glass run 3 using a rubber block 9 formed in the same cut surface shape as the glass run 3.
It is fixed. This glass run cut piece 8 descends diagonally on the bottom wall in a direction away from the door lock 7, and the outer lip 8a and inner lip 8b on the upper surface of the glass run cut piece 8 form a descending flow surface. be.

To obtain this structure, the ends of the glass run 3 and glass run cut piece 8 may be placed in a mold for forming the rubber block 9 to integrate the three, but the rubber block 9 formed separately can be It can be easily manufactured by gluing the glass run 3 and glass run cut piece 8 to the sash, or by bending a length of glass run extending downward from the lower end of the rear side part 2a into the shape shown in Fig. 1. . In addition, the slit shown in the illustrated example is not necessarily essential, and if it is omitted, the elastic restorability of the glass run cut piece 8 can be used to prevent the door glass 1 from moving the glass run cut piece when the door glass 1 is lowered. The door opening may be pushed open toward the 2-7 side.

Since the first embodiment has the structure as described below, most of the water droplets adhering to the door glass flow through the outer lip 3b of the crow run 3 and into the door panel 4, and are not transmitted through other parts of the crow run 3. The water that flows down also flows along both lips 8a, 8b of the glass run cut piece 3, so all the water that has flowed to the glass run cut piece 8 is guided to a position far from the door lock 7 and concentrated. Drip directly below. In this case, the door lock 7 is located at the rear of the glass run 3 and the sash 2 when viewed from directly above, and the rod 11 connecting the outside handle 5 and the door lock 7 is on a horizontal plane that is approximately the same as the lower end 3a of the glass run 3. Since the outside of the glass run 3 is routed inside the vehicle, running water does not splash on the door lock 7 or reach the rod 21.

FIG. 2 is a view corresponding to FIG. 1 showing a second embodiment of the present invention, and this embodiment is characterized by a structure that can also treat water flowing down through the sash 2. That is, in the structure of this embodiment, a deflecting plate 8A having a surface sufficiently larger than the cross-sectional dimension of the sash 2 is fixed to the lower end 3a of the glass run 3 as a guide part, and the deflecting plate 8A is fixed to the lower end 3a of the glass run 3. It is inclined in the direction away from the lock 7. There is a slit in the center of the baffle plate 8A through which the door glass 1 can pass.
Although the IOA is formed, in order for the door glass 1 to pass through smoothly, the edge of the slit 10A may be formed into a lip shape as shown in the figure, or the channel portion may be implanted with hair.

Since the second embodiment has a structure as described above, the mountain water is guided to a position away from the door lock along the downstream surface 10A formed by the upper surface of the deflecting plate 8A, but the deflecting plate 8A is It has a large surface area, so...
It can also catch water that drips down the nozzle 2.

Therefore, not only is almost no water applied to the door lock 7, but the upper side of the door lock 7 is covered by the baffle plate 8A, which has the additional effect of preventing unauthorized unlocking using a wire or the like.

Further, FIG. 3L± shows a third embodiment of the present invention which is effective even when there is a large amount of rainfall, and a deflecting plate 8B similar to the deflecting plate 8A as a guide portion described above has an outer circumferential brim 13 surrounding the outer circumference 3y1. have. Therefore, in this structure,
In addition to the effects described for the second embodiment, the outer periphery flange 13 can prevent water from dripping to areas other than the lower end of the baffle plate 8B.

Effects of the Invention - As is clear from the explanation below, according to the present invention, water can be prevented from splashing on the door lock with a simple structure in which only a guide portion is provided at the lower end of the crow run. It is possible to prevent the door lock from rusting and freezing, and there is no risk of the door opening malfunctioning even when used during long periods of bad weather.
