Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a weather protection device installed in an opening of an automobile body.
This invention relates to a water drain structure that drains water that has entered between the strip and the front windshield to the outside.

Conventional technology Figure 3 shows the opening structure on the front side of the vehicle body to which the conventional water drainage structure is applied, where ■ is the cowl top which is the vehicle body panel, and 2 is the cowl top! 3 is a front pillar, 4 is a front windshield, and 5 is a front windshield 4 attached to a vehicle body opening formed by the cowl top 1, the dash board upper, the front pillar 3, etc. This weatherstrip 5 has a bulge 8 formed along the periphery of the cowl top 1, and an inner lip 6 and an outer lip 7 formed at the same height as the bulge 8. The opening is sealed by coming into contact with the upper surface of the front pillar 3 that has been opened. And the weather
The lower corner of the strip 5, that is, the front pillar 3
An embossed part 9 is formed at the end of the cowl top 1 that joins with the cowl top 1. An embossed part 9 is formed by recessing the bulging part 8 in a substantially inclined shape, and a generally wedge-shaped spacer 10 is placed and fixed on the upper surface of this embossed part 9. There is.

As shown in FIG. 4, this spacer 10 is mainly formed integrally with solid rubber, and the entire lower surface and the side surface on the front pillar 3 side are made of vinyl chloride foam 11.
In addition, near the front pillar 3 on the top surface, there is a drainage groove 12 with a triangular cross section along the vertical direction of the vehicle body.
is formed. Therefore, the weather strip 5
Rainwater that has entered between the inner lip 6 and outer lip 7 of the window, or between the windshield 4 and the weather strip 5,
The water draining groove 1 flows through the upper surface of the bulge 8 of the cowl top l.
It is designed to be discharged to the outside from 2.

Problems to be Solved by the InventionHowever, in the conventional water draining structure described above, since the water draining groove 12 is simply formed on the upper surface of the spacer IO as described above, the outer opening thereof is 12a is
Depending on the inclination angle of the outer surface of the bulging portion 8, that is, the inclination angle of the outer surface 10a of the spacer 10, the direction may be approximately the same as the traveling direction of the vehicle. As a result, there is a risk that rainwater or the like that is about to be discharged from the drainage groove 12 may flow back within the drainage groove 12 due to wind pressure.

Means for Solving the Problems The present invention has been devised in view of the above-mentioned problems of the conventional water drainage structure.In particular, an opening at one end is provided inside the spacer between the weather strip and the spacer. The present invention is characterized in that a facing water drain pipe is provided, and the opening at the other outer end of the water drain pipe is oriented substantially perpendicularly to the traveling direction of the vehicle.

According to the present invention having the above configuration, since the opening at the other end of the drain pipe is formed to be oriented substantially perpendicularly to the direction of travel of the vehicle, the running wind pressure hits the opening at the other end at a substantially right angle. . Therefore, a negative pressure is generated in the vicinity of the opening at the other end, and water between the weather strip and the opening of the vehicle body can be actively discharged to the outside by the so-called atomizing principle.

EXAMPLES Hereinafter, examples of the present invention will be described in detail based on FIGS. 1 and 2. It should be noted that since the water draining structure of this embodiment is also applied to the front side of the vehicle body in the same manner as the conventional one, the same reference numerals are given to the common components in the description.

That is, in the figure, 1 is a cowl top, 2 is a dash board upper, 4 is a windshield, 5 is a weather strip having an inner lip 6 and an outer lip 7, and 9 is formed on a bulge not shown in the figure of the cowl top 1. Embossed part, 10
is a substantially wedge-shaped spacer placed and fixed on the upper surface of the embossed portion 9 with adhesive or the like, and this spacer 10 prevents variations in assembly or processing between the spacer 10, the embossed portion 9, and the weather strip 5. It is integrally molded with sponge rubber that is easily elastically deformed to absorb absorption, and the inner lip 6 and outer lip 7 are in contact with the upper surface 10b to seal the space between the vehicle body opening edge and the front windshield 4. There is.

Inside the front pillar (not shown) side of the spacer IO, a drain pipe 21 as shown in FIG. It is arranged in substantially the same direction as the four ends, and one end opening 21a on the upper side is formed on the same plane as the spacer inner surface 10c, and faces into the cavity C between the inner lip 6 and the outer lip 7. Further, the outer end edge of the water draining pipe 21 protruding from the outer surface 10a of the spacer 10 is cut out in an inclined shape, so that the other end opening 21
b is oriented substantially perpendicular to the vehicle traveling direction (arrow A). In addition, 22 in the figure is a water drain hole which communicates the window glass 4 holding groove 5λ of the weather strip 5 with the above-mentioned cavity C.

According to this embodiment having the above-mentioned configuration, while the vehicle is running, the running wind pressure hits the other end opening 2tb of the drain pipe 21 from a direction substantially perpendicular to the direction of the other end opening 21b.
Negative pressure occurs nearby. Therefore, the drain pipe 21 functions similar to a sprayer. Therefore, if rainwater or the like that has entered between the weather strip 5 and the windshield 4 or between the weather strip 5 and the cowl top L collects on the inner surface 10c of the spacer 10 through the drain holes 22, etc., the water can be drained directly. It is vigorously sucked out through the pipe 21 and quickly discharged from the vehicle through the opening 21b at the other end.

Therefore, not only is it completely possible to prevent water from flowing back from the drain groove as in the past, but on the contrary, rainwater and the like can be positively discharged to the outside of the vehicle.

The other end opening 21b of the water draining pipe 21 needs to be oriented substantially perpendicularly to the wind pressure when the vehicle is running, so the outer end opening 21b of the water draining pipe 21 is adjusted according to the inclination angle of the front part of the vehicle body, that is, the spacer 10. The inclination angle can also be changed arbitrarily.

Further, although the above embodiment shows the case where the present invention is applied to the front side of the vehicle body, it is also possible to apply it to the rear side of the vehicle body.

Effects of the Invention As is clear from the above explanation, according to the water draining structure for the edge of an automobile windshield according to the present invention, an opening at one end is formed inside the spacer between the weather strip and the spacer. Since a water drain pipe facing the water drain pipe is provided and the other end opening of the water drain pipe is oriented approximately perpendicularly to the running direction of the vehicle, negative pressure is generated near the other end opening when the vehicle is running, so to speak. Since it is in a misting state, not only is water prevented from flowing back as in the conventional case, but also the water accumulated on the upper surface of the spacer can be sucked out and quickly discharged to the outside.
