Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a drainage structure for draining water accumulated in a frame portion of a sliding window to the outside.

BACKGROUND OF THE INVENTION Some automobiles are equipped with sliding windows. As shown in FIG. 1, this slide window 1 conventionally has a glass run 3 inserted into a frame 2 having a substantially U-shaped cross section, and a pair of windows fitted into glass grooves 3a and 3b of the glass run 3. The glasses 4, 4a are made to slide. A weather strip 5 is provided to cover the outside of the frame 2.
The frame 2 is inserted into a panel 6 such as a door panel or a vehicle body panel through the frame 2.

Incidentally, in the frame 2, a first through hole 10 is formed in the glass groove 3a on the outside of the vehicle, passing through the glass run 3, as shown in FIG. A second through hole 11 is formed at a position corresponding to the through hole 10, and the glass groove 3 is inserted through these first and second through holes 10, 11.
A drainage structure is provided to drain water accumulated in the chamber a to the outside.

However, since the frame 2 and the weather strip 5 are formed separately and then assembled, elastic deformation of the weather strip 5 causes the first and second through holes 10 and 11 to open. It shifts as shown in Figure 2. Therefore, the area of the through-holes through which water is actually drained becomes significantly smaller, resulting in a significant deterioration of the water-draining efficiency. There was a problem in that the particles entered between the frame 2 and the frame 2 and corroded the frame 2.

Purpose of the Invention In view of these conventional problems, the present invention provides a water drainage structure for a sliding window that significantly improves water drainage efficiency and efficiently drains water that has entered between the frame and the weather strip. The purpose is to

Structure of the Invention In order to achieve the above object, the present invention includes a frame having a substantially U-shaped cross section into which a window glass is slidably fitted, and a weather strip covering the outside of the frame. In a slide window in which first and second through holes for draining water are formed at the bottom of the frame and the weather strip, respectively, a hole is provided at the frame joint of the weather strip in a continuous direction in the frame extension direction. The extending concave groove forms a water conduit that passes through the first and second through holes, and the bottom surface of the concave groove has a protrusion or a concave line that passes through the second through hole. The water that reaches the gap between the through hole and the through hole of the weather strip easily reaches the through hole of the weather strip through the water conduit, and the water flows through the protrusion or groove. Since it becomes easier to flow, water drainage efficiency is further improved, and water that enters between the frame weather strip and the frame weather strip is also discharged through the water conduit. In addition, since the protrusions or grooves are formed on the bottom of the groove, the groove will not be blocked even if the bottom of the weather strip is deformed.

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

That is, FIGS. 3, 4, and 5 show a water drainage structure according to an embodiment of the present invention, in which a water conduit 20 is formed between the frame 2 and the weather strip 5. As shown in FIG. This water conduit 20 has first and second through holes 1
It is provided on the outside of the vehicle where weather strips 0 and 11 are formed, and is mainly constituted by a groove 21 that extends continuously in the extending direction of the frame 2 at the joint portion of the weather strip 5 with the frame 2. The width w1 of this groove 21 is wider than the width w2 of the second through hole 11, and the first and second through holes 1 are formed approximately at the center of this groove 21.
0 and 11 are arranged. Also,
A protrusion 22 passing through the second through hole 11 is formed on the bottom surface of the groove 21 .

With the above configuration, when the weather strip 5 is assembled to the frame 2, even if the first and second through holes 10 and 11 are disposed out of alignment as shown in FIG. The first and second parts are exposed to water in the groove.
When the water falls into the misaligned portion X of the through holes 10 and 11, it falls into the groove 21 and is guided to the second through hole 11 through the groove 21. Further, by providing the groove 21, water is normally prevented from entering the part where the frame 2 and the weather strip 5 are directly joined, but even if water does not enter the part where the frame 2 and the weather strip 5 are directly joined, Even if it is, it is easily returned to the groove 21 and discharged from the second through hole 11 to the outside. By the way, in this embodiment, since the protrusion 22 is further provided in the groove 21, water can easily flow along the protrusion 22, and the water drainage efficiency can be further improved.

In the above embodiment, the protrusion 2 is provided in the groove 21.
2 is shown, but as shown in FIG.
It can perform the same functions as . Furthermore, the seventh
As shown in the figure, both sides of the groove 21 may be inclined, and in this case, the first and second through holes 10, 11
A large amount of deviation can be tolerated.

Effects of the Invention As explained above, in the water drainage structure of the sliding window of the present invention, first and second through holes for water drainage are formed at the bottom of the frame and the weather strip, respectively. A conduit that passes through the first and second through holes is formed in the frame joint by a concave groove that extends continuously in the frame extension direction, and the bottom of the concave groove has a protrusion or a concave that passes through the second through hole. Since the strips are formed, even if the through holes are misaligned due to assembly errors between the frame and the weather strip, water that falls from the through holes on the frame side will flow through the water conduit to the weather strip. The water is easily guided to the side through holes and flows easily along the protrusions or grooves, which greatly improves water drainage efficiency. In addition, it significantly reduces water intrusion into the directly joined part between the frame and weather strip, and the water that has entered into this part can be easily drained into the water conduit, thereby preventing corrosion of the frame. can be prevented or significantly reduced. Furthermore,
The protrusions or grooves formed in the groove provide a number of excellent effects, such as preventing the groove from being blocked even if the bottom of the weather strip is deformed.
