Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an automobile window weather strip having drainage holes.

Conventional technology Wind glasses such as front windshields and rear windshields of automobiles are shown, for example, in "Complete Book of Automotive Engineering, Vol. 13, Passenger Car Body", page 94, published by Sankaido Co., Ltd. on April 20, 1981. In some cases, it is attached to the vehicle body opening via a window weather strip. To explain this in detail with reference to FIG. 5, reference numeral 1 denotes a window weather strip, and the flange fitting groove is fitted into the flange portion 11 formed on the outer periphery of the vehicle body opening 10. 2, and a glass fitting groove 3 into which the peripheral edge of the window glass 12 is fitted is formed on the inner peripheral edge. Thereby, a window glass 12 is attached to the vehicle body opening 10 via the window weather strip 1. In addition, a drainage hole 4 communicating with the outside of the vehicle is formed in the groove bottom 3a of the glass fitting groove 3 on the lower side 1a of the window weather strip 1, so that rainwater in the glass fitting groove 3 and car wash water can be removed. Penetrating water is discharged to the outside of the vehicle.

Problems to be Solved by the Invention In the drainage structure of the window weather strip 1, water flows downward along the side portion 1b of the window weather strip 1, and the water flows downwardly from the window glass 12 on the side portion 1b. This is because permeated water such as rainwater that has permeated into the gap between the fitting groove 3 becomes difficult to flow smoothly from the lower corner part into the drain hole 4 of the lower side part 1a, and tends to stay in corners such as the lower corner part. There was a risk that water could enter the passenger compartment due to capillary action.

Incidentally, this phenomenon is more likely to occur when the lower side portion 1a of the window weather strip 1 is curved upward in an arc shape and its lower corner portion is located at a lower level than the drain hole 4.

Therefore, this invention has developed an automobile window weather strip that can discharge water straight from the glass fitting groove at the lower corner to eliminate water accumulation and reliably prevent water from entering the vehicle interior. It is intended to provide a

Measures to solve the problem: The bottom of the glass fitting groove in the lower corner of the window weather strip communicates with the outside of the vehicle in a straight line along the extension direction of the bottom of the glass fitting groove in the side part. A water drain hole is formed therein, and seal ribs extending straight from both sides of the glass fitting groove in the side portion to the water drain hole in the lower corner portion are formed to protrude straight.

Function Rainwater and other water that flows downward along the sides of the window weather strip is discharged straight to the outside of the vehicle through the drainage holes in the glass fitting groove at the lower corner, and remains in the glass fitting groove. There's nothing to do. This further improves water drainage efficiency and prevents water from entering the passenger compartment.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those in the conventional structure are denoted by the same reference numerals.

In FIGS. 1 to 4, reference numeral 1 denotes a rubber window weather strip, which has a flange fitting groove 2 formed on its outer periphery to be fitted into a flange portion 11 of a vehicle body opening 10, and has a flange fitting groove 2 on its outer periphery. The window weather strip 1 has a glass fitting groove 3 formed on its periphery into which the periphery of the window glass 12 is fitted.
This is similar to the prior art in that a drain hole 4 communicating with the outside of the vehicle is formed in the groove bottom 3a of the glass fitting groove 3 on the lower side 1a. Here, as shown in FIG. 1, the groove bottom 3a of the glass fitting groove 3 of the lower corner part 1c of the window weather strip 1 is A drain hole 5 is formed straight along the extension direction to communicate with the outside of the vehicle. Further, the groove bottom 3a of the glass fitting groove 3 is formed in a sawtooth shape to allow the permeated water to flow smoothly, and a plurality or a single triangular sealing rib 3b is formed protruding from both sides thereof. There is. A triangular seal rib 3b extending from both sides of the glass fitting groove 3 of the side portion 1b to the water drain hole 5 is also formed to protrude straight;
The penetrating water flowing downward along the side portion 1b can be smoothly discharged to the outside of the vehicle. Incidentally, an outer seal lip 6 and an inner seal lip 7 are formed protruding from the outer peripheral edge of the window weather strip 1 on the outer side of the vehicle so as to come into close contact with the panel 13 on the outer side of the vehicle forming the flange portion 11.

The window weather strip 1 having such a structure is integrally formed into a ring shape as shown in FIG. 4 in the following manner. That is, the extruded side portion 1b, lower side portion 1a, and upper side portion 1d are placed in a mold (not shown), and then the lower corner portion 1c and upper corner portion 1e are molded and fused to the respective side portions. let At this time, the drain hole 5 and the like in the lower corner portion 1c are formed by a core or the like.

According to the structure of the embodiment described above, water such as rainwater or car wash water that descends along the seal rib 3b of the side part 1b of the window weather strip 1 is transferred to the window glass 12 and the glass fitting groove 3 of the side part 1b. It penetrates into the gap between and flows toward the lower corner portion 1c. This permeated water is discharged straight to the outside of the vehicle from the drain hole 5 in the lower corner portion 1c. Further, the permeated water that has penetrated into the glass fitting groove 3 of the lower side portion 1a is discharged to the outside of the vehicle through the drain hole 4. In this way, the lower corner part 1
By forming the drain hole 5 on the c side, in conjunction with the other drain hole 4, the drainage efficiency of permeated water is further improved.

In addition, since the drain hole 5 of the lower corner part 1c is formed in the flow direction of the permeated water, the lower corner part 1c
Penetrating water does not remain in the glass fitting groove 3 of c, ensuring sufficient water drainage, and water permeates through the glass fitting groove 3 and entering the vehicle interior. can be prevented.

In the above embodiment, the lower side 1a of the window weather strip 1 extends approximately horizontally, but the lower side 1a of the window weather strip 1 is curved upward in an arc shape. However, the same effect as described above can be obtained even when the lower corner portion 1c is located lower than the lower side portion 1a.

Effects of the Invention As described above, according to the present invention, in the glass fitting groove at the lower corner part of the window weather strip, there is a permeation that flows downward along the groove bottom of the glass fitting groove at the side part. Water tends to stay there, but this permeated water can be removed by drain holes formed straight along the bottom of the glass fitting groove in the lower corner along the extension direction of the groove bottom of the glass fitting groove in the side area. Water can be drained out of the vehicle smoothly through the straight protruding seal ribs that extend from both sides of the glass fitting groove to the water drain hole, ensuring sufficient drainage and preventing water from entering the passenger compartment. can be prevented, and drainage efficiency can be further improved.
