Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a sealing member that seals between glass slides for automobiles.

[Conventional technology]

Conventionally, the structure was as shown in FIGS. 6 to 8. In FIG. 6, the side edge of the window glass 1 is fitted into a slide glass groove formed at the periphery of an opening in the vehicle body of an automobile to seal the space between the window glass 1 and the slide glass 2 that can be slid left and right. An anchor part 5a of a sealing material 5 made of a soft synthetic resin such as sponge rubber or vinyl chloride is fitted into a fitting groove 3a of a mounting base 3 made of a synthetic resin member that is fitted and fixed to the part. and,
As shown in FIG. 7, the sealing material 5 includes a hollow seal portion 5a having a substantially circular cross section, an anchor portion 5b that fits into the fitting groove 3a of the mounting base 3, and a connecting portion that connects the hollow seal portion 5a and the anchor portion 5b. 5c.

FIG. 8 is a diagram showing the relationship among the window glass 1, slide glass 2, mounting base 3, and sealing material 5, and shows the window glasses 1 and 2 in a retracted state. The hollow seal portion 5a is pressed against the slide glass 2, and the hollow portion is deformed.

However, as shown in FIG. 9, when the slide glass 2 is slid in the direction of the arrow Y, the sealing material 5 is dragged in the moving direction of the slide glass due to the surface resistance between the slide glass surface and the hollow seal portion 5a. It becomes tilted and deformed, resulting in a state called "falling over" or "falling over."

[Problem that the invention seeks to solve]

When the sealing material falls over, the sealing surface of the hollow seal part does not come into contact with the slide glass surface properly, resulting in incomplete sealing, leading to rainwater intrusion and irregular deformation resulting in poor appearance. .

Therefore, an object of the present invention is to provide a seal structure that can regulate the inclination deformation of the hollow seal material 5 and ensure sealing performance.

[Means for solving problems]

A protrusion is formed on one or both of the sealing material and the mounting base, which comes into contact with the hollow seal when the hollow seal is tilted by a predetermined value or more to prevent the hollow seal from falling.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 5. In addition, in the description, the same parts as those in the description of the prior art are given the same reference numerals.

FIG. 1 shows a first embodiment of the invention. The anchor part 5b of the sealing material 5 is fitted into the fitting groove 3a for mounting of the sealing material 5 formed in the mounting base 3 which is fitted and fixed to the end of the window glass 1, and the sealing part 5a of the mounting base 3 is fitted. A protrusion 3b and a protrusion 3c are formed on both sides of the seal 5a to prevent the seal 5a from falling to the left or right in the drawing due to sliding of the slide glass.

FIG. 2 shows a second embodiment of the present invention, in which a protrusion for regulating the inclination of the seal portion 5a is formed as a protrusion 3c on the side of the window glass 1 with respect to the seal portion 5a of the mounting base 3; For the seal portion 5a,
The protrusion 5d is formed on the tip side of the window glass 1 and protrudes from the seal portion 5a toward the mounting base 3.

In the third embodiment shown in FIG. 3, a protrusion is formed opposite to that in the second embodiment shown in FIG. In other words, the protrusion 5e is placed on the window glass 1 side of the seal portion 5a.
There is a protrusion 3 on the tip side of the windshield 1 on the mounting base 3.
b.

The fourth embodiment shown in FIG. 4 is an embodiment in which protrusions 5e and 5f are formed on both sides of the seal portion 5a so as to come into contact with the mounting base 3 when tilted.

FIG. 5 shows a fifth embodiment, in which the space between the hollow seal part 5a and the mounting base 3 is filled by protrusions 5g and 5h connected to both sides of the connecting part 5c of the sealing material 5, and the hollow seal It acts to prevent the portion 5a from falling down.

〔Effect of the invention〕

As explained above, since the hollow seal part is prevented from falling down, it
The hollow seal part abutted correctly and sealing performance was ensured. In addition, since it does not fall down irregularly, it has the effect of maintaining the appearance quality.
