Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weather strip that is attached to the periphery of a wind panel, such as a front window, rear window, or side window of an automobile, where the window panel is fixed to the vehicle body.

As shown in FIG. 1, this type of weather strip 1 is installed by fitting a flange fitting groove 3 into a flange 2a formed on a vehicle body panel 2, and is formed outside the flange fitting groove 3. The window panel 5 is fitted and fixed into the panel fitting groove 4 which has been provided. By the way, conventionally, a weather strip 1 is provided at the bottom of the panel fitting groove 4.
A drain hole 6 communicating with the outside is formed to drain water such as rainwater that has entered between the outside of the wind panel 5 and the panel fitting groove 4 from the drain hole 6,
Water is prevented from entering the vehicle interior (right side in the figure) from the inside of the window panel 5 in the panel fitting groove 4. By the way, the panel fitting groove 4
There is a protrusion 7 on the bottom that extends in the length direction over the entire length.
is formed, and the wind panel 5 is formed by the protrusion 7.
A gap is formed between the peripheral edge and the bottom, and water in the panel fitting groove 4 flows through the gap to the water drain hole 6.
It is becoming more and more guided by.

However, it is impossible to set a large gap between the panel fitting groove 4 and the window panel 5 due to the holding force of the window panel 5. Therefore, the gap around the periphery of the drain groove 6 becomes smaller, and water cannot be drained smoothly from the drain hole 6 due to surface tension and the like.
For this reason, water that has accumulated inside the panel fitting groove 4 without being completely drained from the drain groove 6 is removed from the wind panel 5.
There was a problem in that it penetrated the inside of the panel fitting groove 4 and the close contact area of the panel fitting groove 4 and entered the vehicle interior.

In view of such conventional problems, an object of the present invention is to increase the gap around the periphery of the drain hole so that water accumulated in the panel fitting groove can be smoothly drained outward. .

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Incidentally, in describing this embodiment, the same parts as in the conventional structure will be described with the same reference numerals.

That is, FIGS. 2 and 3 show a weather strip 1a showing an embodiment of the present invention, which is attached to a flange 2a of a vehicle body panel 2 through a flange fitting groove 4, and is attached to a wind panel in the panel fitting groove 4. The window panel 5 is fixed to the vehicle body by fitting the peripheral edge portions of the window panel 5. By bringing the tip of the protrusion 7 formed at the bottom of the panel fitting groove 4 into contact with the periphery of the wind panel 5, a gap is formed for water to pass through, and
The protrusions 7 also provide a seal between the wind panels 5. Further, on both inner walls of the panel fitting groove 4, lips 4a, 4a are formed which abut on both sides of the wind panel 5, respectively, to seal between them and increase the holding force of the wind panel 5. ing.

Here, in this embodiment, at the periphery of the drain hole 6 formed at the bottom of the panel fitting groove 4, the panel fitting groove 4
Wind panel 5 over both inner walls and bottom of
A recess 10 is formed to increase the gap between the panel fitting groove 4 and the inside of the panel fitting groove 4.

With the above configuration, the panel fitting groove 4 is inserted between the upper end of the panel fitting groove 4 and the outside of the wind panel 5.
When water such as rainwater that has entered the drain hole 6 reaches the periphery of the drain hole 6, it easily collects in the drain hole 6 through the recess 10.
The water is discharged from the drain hole 6 to the outside of the vehicle. In other words, the influence of surface tension and the like on the water that has reached the periphery of the drain hole 6 is significantly reduced by the recessed portion, allowing smooth discharge from the drain hole 6. Therefore, water is prevented from being collected in the panel fitting groove 4 without being completely drained from the drain hole 6 and from entering into the interior of the vehicle, as in the conventional case.

It should be noted that the suitable gap size for the recess 10 is about 1 mm to 1.5 mm; if it is less than this, the water discharge performance will be reduced, and if it is more than this, the holding force of the weather strip 1a of the wind panel 5 will be reduced. , a large amount of rainwater will permeate near the drain hole 6.

As explained above, the weather strip for a vehicle window of the present invention is fitted into a flange formed on the periphery of a vehicle body opening, and has a panel fitting groove for fitting a wind panel into the opening. A weather strip having a protrusion formed at the bottom of the panel fitting groove and abutting the periphery of the wind panel, and a protrusion formed on both inner walls of the panel fitting groove and provided on both sides of the wind panel. a lip that contacts each other, a water drain hole formed at the bottom of the panel fitting groove, a water drain hole formed at the periphery of the water drain hole over both inner walls and the bottom of the panel fitting groove, and a window panel and a panel fitting groove. Since a recess is provided to increase the gap with the inside, water such as rainwater that has entered the panel fitting groove reaches the periphery of the drain hole and is then absorbed by the recess formed on the periphery due to surface tension, etc. The influence of this is also significantly reduced, allowing smooth drainage from the water drain hole. Furthermore, in the present invention, by forming the recessed panel fitting groove over both inner walls thereof, air flow can be improved and the exhaust effect can be significantly improved. Therefore, water that cannot be completely drained from the drain hole and accumulates in the panel fitting groove as in the conventional case is reliably prevented from entering the interior of the vehicle. Also,
The protrusion formed at the bottom of the panel fitting groove and the lip formed on both inner walls of the panel fitting groove can significantly improve the sealing performance between the weather strip and the wind panel. This lip provides various excellent effects such as significantly increasing the holding force of the window panel.
