Description

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

-Prior Art- As is well known, most of the water droplets adhering to the surface of the door glass 1 of an automobile door as shown in FIG. The water that flows down passes through the glass run 3 fitted to the sash rear side part 2a and enters the inside of the door panel 4. In recent years, automobile door odors have been removed from the sash rear side 2a as shown in the second figure in order to reduce the weight of the car body or eliminate interference with the door lock 7.
The glass run 3 is terminated near the outside handle 5 inside the door panel 4, and the lower end of the glass run 3 is terminated in a state slightly protruding from the sash rear side portion 2a. In many cases, it is supported by a vibration damping member (not shown).

By the way, 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, so that water flowing down the glass run 3 into the door panel 4 forms irregular water droplets from the substantially horizontal lower end surface 6 of the glass run 3. A door lock 7 is located near the rear side portion 2a of the sash, and the water droplets scattered from the lower end surface 6 of the glass run 3 hang on the door lock 7. For this reason, conventionally,
Although the rotating parts of the door lock 7 are subjected to strict anti-corrosion treatment or grease is applied to the same parts, if raindrops etc. adhere to the door lock 7, electrolytic corrosion may occur or the grease may flow out, so be sure to It cannot be expected to have a strong rust prevention effect, and in cold regions,
There was a risk that the water on the door lock would freeze and cause the door lock to malfunction.

-Object of the Invention- In view of the malfunction and rust prevention problems of conventional door locks as described above, an object of the present invention is to provide a structure that prevents water droplets flowing down the glass run from getting on the door lock. There is something to be gained.

-Structure of the Invention- In order to achieve this object, the present invention supports the edge of the door glass with a seal lip that fits into the sash and extends diagonally inward from both opening edges of the U-shaped cross section. At Glass Run,
At the lower end of the glass run located on the rear side of Satsushi,
It is proposed to provide a guide section that extends diagonally downward in a direction away from the door lock and has a slit that allows the door glass to be raised and lowered.

-Embodiments- Hereinafter, details of embodiments of the present invention will be explained with reference to FIGS. 1 to 3.

FIG. 1 is an enlarged view corresponding to FIG. 5 of an automobile door showing a first embodiment of the present invention, and in this embodiment, a glass run cut piece 8 is used as a guide portion. That is, a cut piece 8 of the glass run 3 is fixed to the lower end 3a of the glass run 3 using a rubber block 9 having a cut surface similar to that of the glass run 3. This glass run cut piece 8 has a bottom wall that slopes downward in a direction away from the door lock 7.
Outer lip 8 on the top surface of glass run cut piece 8
A and the inner lip 8b form a descending flow surface. To obtain this structure, the ends of the glass run 3 and the glass run cut piece 8 may be placed in a mold for forming the rubber block 9 to integrate the three, but the glass run 3 and the glass run cut piece 8 may be placed in a mold to form the rubber block 9 to integrate the three. It can be easily manufactured by gluing the run 3 and the glass run cut piece 8, or by bending a single glass run extending downward from the lower end of the rear side portion 2a of the sash into the shape shown in Fig. 1. . Further, slits 10 are formed in the bottom wall of the glass run cut piece 8, and the door glass 1 passes between the slits 10 when the door glass 1 is raised and lowered so that the raising and lowering of the door glass 1 is not hindered.

Since the first embodiment has the above structure,
Most of the water droplets adhering to the door glass flow through the outer lip 3b of the glass run 3 and flow into the door panel 4, and water flowing down through other parts of the glass run 3 also flows into both lips 8 of the glass run cut piece 3.
a, 8b, all of the water that has traveled to the glass run cut piece 8 is guided to a position far from the door lock 7, where it is concentrated and drips directly below. In this case, when viewed from directly above, the door lock 7 is located at the glass run 3.
and a rod 11 located at the rear of the sash 2 and connecting the outside handle 5 and the door lock 7.
Door lock 7
There is no possibility that running water will splash on the rod 11 or that water will be transmitted to the rod 11. Further, since the slit 10 is formed, the operating force for raising and lowering the door glass 1 is almost the same as in the conventional case, and there is no problem in raising and lowering the door glass 1.

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 used as a guide part. It is inclined in the direction away from 7. Although a slit 10A is formed in the center of the baffle plate 8A through which the door glass 1 can pass, in order for the door glass 1 to pass through smoothly, the edge of the slit 10A is formed into a lip shape as shown in the figure. Alternatively, you can have hair transplanted in the path.

Since the second embodiment has the above structure,
Rainwater will be guided to a position away from the door lock along the flow down surface 10A formed by the upper surface of the baffle plate 8A, but since the baffle plate 8A has a large surface area, it will drip down the sash 2. It can also catch water. Therefore, not only is there almost no water on the door lock 7, but
Since the upper side of the door lock 7 is covered by the baffle plate 8A, there is an additional effect of preventing unauthorized unlocking using a wire or the like.

Further, FIG. 3 shows a third embodiment of the present invention which is effective even when there is a large amount of rainfall, in which a deflecting plate 8B similar to the deflecting plate 8A as a guide portion described above has an outer circumference collar 13 surrounding three sides of the outer circumference. have. Therefore, with this structure, in addition to the effects described for the second embodiment, the outer peripheral collar 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 above description, 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 glass run. Rust and freezing can be prevented, and there is no risk of the door lock malfunctioning even when used during long periods of bad weather.
