Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a door glass weather strip mounted along an inner peripheral surface of a door frame of an automobile.

[Prior Art] A door frame 1 is used for an automobile door as shown in FIG.
A door glass weather strip is attached along the inner peripheral surface of the.

As a door glass weather strip, as shown in FIG. 5, a sealing wall 34 is provided in front of the bottom 31 of the main body having a U-shaped cross section.
Is provided and the space between the seal wall 34 and the bottom 31 is hollow. In this type, in order to improve the sealing performance, the seal wall 34 has a V-shaped cross section,
Out of the car 341 which is pushed up by the door glass 2
Is substantially vertical to the glass pushing-up direction and has a thin wall, and the portion 341 is supported by a portion 342 on the inside of the vehicle that is inclined in the glass pushing-up direction and has a thick wall. Things have come to be used.

The door glass weather strip 3 in the illustrated example is integrated with a holding portion 4 that forms a trim, and the holding portion 4 is attached to a flange 11 of the door frame 1 so that the door frame 1
Is supported along the inner peripheral surface of.

[Problems to be Solved by the Invention] In the door glass weather strip 3 described above, when the door glass 2 is lifted and closed as shown in FIG. , The inner half portion) 342 and the inner surface of the outer periphery of the door glass 2 are not completely in contact with each other, and a gap a is formed.

In order to improve the sealing and sound insulation properties, the gap a
It is desired that the outer periphery of the door glass 2 is completely covered with the seal wall 34 without causing any trouble.

In addition, a slight variation inevitably occurs in the rising end position of the door glass 2 depending on the vehicle. By the way, when the rising end is high, the portion of the seal wall 34 outside the vehicle (hereinafter referred to as the outer half)
341 is pushed up further by the door glass 2. However, since the inner half portion 342 is thick and does not deform, the molding lip 32 connected to one end of the outer half portion 341 is pushed inward and the tip of the molding lip 32 pushes the door glass 2 to push the door glass 2. Moves toward the room. As a result, the gap a disappears, but the step between the outer surface of the door frame 1 and the door glass 2 increases.

Recently, the body tends to be flush with the door frame and the door glass, and the above-mentioned increase in the step is not preferable.

Therefore, an object of the present invention is to provide a door glass weather strip that wraps around the outer periphery of a door glass and has excellent sealing properties and sound insulation properties, and that does not increase the step even when the door glass rising end position is high. To do.

[Means for Solving the Problems] As shown in FIG. 2, the present invention provides a seal wall 34 having a V-shaped cross section to form a hollow portion, and the door glass 2 pushes up the seal wall 34. In a door glass weather strip having a thin outer half 341 and an inner half 342 thicker than the outer half 341, a thinned portion 343 is formed at the root of the inner half 342 to form a seal wall. When the door glass 2 is pushed up by the door glass 34, the root can be bent.

[Operation and Effect] When the door glass 2 is lifted and closed as shown in FIG. 3, the pushing force of the door glass 2 is the outer half 34 of the seal wall 34.
When transmitted from 1 to the inner half 342, the root of the inner half 342 is bent and pivoted in a direction close to a right angle to the surface of the door glass 2, and the seal wall 34 closely adheres to the inner surface of the outer periphery of the door glass 2. , Sealing performance and sound insulation are improved.

If the rising edge of the door glass 2 is particularly high, the inner half 34
2 is closer to the door glass 2 in the direction at a right angle. Therefore, even if the molding lip 32 presses the door glass 2 toward the inside of the vehicle, the door glass 2 is supported by the inner half portion 342 against the pressing force and does not move toward the inside of the vehicle. Therefore, there is no increase in the level difference between the outer surface of the door frame 1 and the door glass 2 as in the conventional case.

[Embodiment] FIGS. 1 to 3 show a first embodiment of the present invention.

The door glass weather strip 3 is made of rubber and has an integral structure with the holding portion 4.
It is held by the flange 11 of the.

The body of the door glass weather strip 3 is made of solid rubber and has a U-shaped cross section, and extends in a right angle direction from a bottom portion 31, a molding lip 32 extending from the vehicle outer side end portion of the bottom portion 31 in a direction perpendicular to the vehicle outer side end. The support wall 33 is integrated with the holding portion 4 forming a trim having a U-shaped cross section. In front of the bottom portion 31, there is formed a seal wall 34 having a V-shaped cross section, one end of which is connected to the tip portion of the molding lip 32 and the other end of which is connected to a corner portion of the bottom portion 31 and the supporting wall 33. A hollow structure is formed between the seal wall 34 and the seal wall 34.

The seal wall 34 is made of sponge rubber, and the outer half portion 341 pushed up by the door glass 2 is substantially perpendicular to the door glass pushing up direction and has a thin uniform thickness. Inner half 342 is outer half 3
Although the thickness gradually increases from the 41 side toward the root, a lightening portion 343 is formed inside at the root. And the root is the bottom when the seal wall 34 is pushed up by the door glass 2.
It has a thickness that allows it to bend in 31 directions.

FIG. 4 shows a second embodiment, in which the door frame 1 has a substantially Z-shaped cross section, and the door weather strips 6 elastically contact the door opening edge of the automobile body at the upper and lower stages of the outer peripheral surface thereof, respectively. 7 is attached. Holding part 4 for the door glass weather strip 3 mounted on the inner surface of the door frame 1.
Is formed by a thick-walled extension that linearly extends from the support wall 33, and a recess 41 is formed at the tip of the interior side surface of the vehicle to engage with a protrusion formed at the lower corner of the door frame 1. It's tightened. A recess 35 is formed on the outer surface of the root of the molding lip 32, and a projection formed on the lower end of the outer surface of the door frame 1 is engaged with the recess 35. The front end of the molding lip 32 of the door glass weather strip 3 and the bottom 31 of the main body
The structure of the seal wall 34 that connects the corner portion formed by the support wall 33 and the support wall 33 is substantially the same as that of the first embodiment, and the description thereof will be omitted.

In the door glass weather strip configured as described above, when the outer half portion 341 of the seal wall is pushed up by the door glass 2 when the door glass is closed, as shown in FIG.
The root portion of 342 is slightly bent, and as a whole rotates about the root portion in a direction approaching the bottom 31, that is, in a direction approaching a direction perpendicular to the door glass surface. This makes the inner half 342
Since the front end of the door glass pushes the inner surface of the upper end of the door glass 2 toward the outside of the vehicle, it closely adheres to the glass surface, and the gap a unlike the conventional door glass weather strip shown in FIG. 6 does not occur. Therefore, the sealing property is improved and the sound insulation effect is also improved.

Further, when the rising end position of the door glass 2 becomes too high, the inner half portion 342 of the seal wall rotates in a direction closer to a right angle with respect to the glass surface. On the other hand, the molding lip 32 also pushes the upper end of the door glass 2 toward the inside of the vehicle with its root as the center. However, this pressing force is applied from the inside of the vehicle to the inner half 342.
And the inner half 342 has a sufficient thickness that it does not bend with respect to the pressing force along its longitudinal direction.
The door glass 2 is never pushed inward. Therefore, even if the rising edge of the door glass 2 becomes too high, the step between the outer surface of the door frame 1 and the outer surface of the door glass 2 does not increase.
