Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a sealing device for a sashless window for an automobile.

BACKGROUND ART FIGS. 11-13 show a conventional sealing device for a sashless door, in which a weather strip 17 is attached via a retainer 14 to a periphery 13 of an approximately upper half of an opening in a vehicle body.

A clip 15 is installed in a part of the retainer 14, and a holder portion 16 coated with hard resin is formed at the tip of the clip 15.

With this configuration, the weather strip 1
7 comes in close contact with the door window glass 5 to seal the inside and outside of the vehicle interior, and the holder part 16 of the clip 15 holds the door window glass 5 in its normal position against the force that sucks the door window glass 5 out when the car is running at high speed. (See Utility Model Application Publication No. 50-66323).

Problem to be Solved by the Invention Since a large force is concentrated on the holder portion 16 of the shift lip 15 due to the suction action of the door window glass 5 during high-speed driving, the holder portion 16 is coated with a hard resin to increase its rigidity. , to improve durability. Therefore, when the door window glass 5 vibrates when driving on a rough road, the upper part of the door window glass 5 collides with the holder part 16, causing an unpleasant hitting sound.

Therefore, the present invention is capable of reliably holding the window panel in its proper position against the force that sucks the window panel out when the vehicle is traveling at high speed, and that is capable of suppressing the knocking noise caused by the collision of the window panel when driving on rough roads. An object of the present invention is to provide a sealing device for a sashless window for an automobile, which can avoid the occurrence of .

Means for Solving the Problem A retainer for holding the weather strip is attached to the periphery of the upper half of the vehicle body opening, and a flange portion is provided on the upper side of the retainer to stand up approximately perpendicular to the mounting surface of the retainer. A U-shaped portion is bent at the tip of the seven-rank portion of the lever, and the U-shaped portion is brought into close contact with the weather strip. A holder made of a soft elastic material is attached to restrict movement of the window panel in the suction direction.

Function When driving at high speed, the window panel tends to be sucked outward due to the negative pressure generated near the window panel, but the peripheral edge of the window panel elastically contacts the holder and the 7-rank part Outward movement is restricted.

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 shows a first embodiment of the present invention applied to a door window wrapper 9 without a door window, in which a weather strip 2 for the door window 9 is provided on the periphery 1 of approximately the upper half of the vehicle body opening.
The retainer 3 is attached via the retainer 3 and the sheet-like sealing material S.◇ On the upper side of the retainer 3 that houses and holds the mounting base 2a of the weather strip 2, there is a mounting surface 3alt of the retainer 30 to the vehicle body panel 4 approximately vertically. Rising 7 rank part 3
b is provided, and the tip KU-shaped portion 3C of this seven-rank portion 3b is bent inward. This U-shaped portion 3C extends substantially parallel to the door window glass 5 as a window panel, and is disposed close to the opening/closing locus of the door window glass 5.

The U-shaped portion 3C has a holder 6 made of a soft elastic material such as vinyl chloride, whose lip 6a abuts against the outer peripheral edge of the door window glass 50 to restrict movement of the door window glass 5 in the suction direction. It is glued. Specifically, the holder 6 has a base portion to which the U-shaped portion 3CK is adhered,
The holder 6 includes the lip 6a protruding from the lower end and the lip part 6b that comes into close contact with the drip molding 7 joined to the retainer 3, and this holder 6 follows the opening/closing trajectory (X) of the door window glass 5 when the door is opened/closed. - interferes with the displacement trajectory (Y-Y),
The dimensions are set such that displacement of the door window glass 5 can be prevented.

According to the structure of the embodiment described above, the 7th rank portion 3b protrudes in a position that does not interfere with the opening/closing locus of the door window glass 5, so that the door window glass 5 can be moved from the door closed state shown by the chain line in FIG. 1 to the door opening state. Even if it moves in parallel to the outside of the vehicle, it will not interfere with the holder 6. Furthermore, when the door window glass 5 receives suction force toward the outside of the vehicle during high-speed driving, the door window glass 5 swings from the position indicated by the chain line in the same figure using the regulator support part (not shown) as a fulcrum, and its upper end becomes Y
Although the door window glass 50 moves on a displacement trajectory shown by the -Y line, it is stopped at the seventh rank portion 3b via the holder 6, and movement of the door window glass 50 to the outside of the vehicle is restricted.

Here, the holder 6 is made of a soft elastic material as described above.
In addition, a lip 6a is protruding from the lower end, so that the contact area with the door window glass 5 is large and the contact surface pressure is low, so even if the door window glass 5 collides with the core holder 6 while driving, there will be no unpleasant impact. It does not produce any sound. Even if the contact area between the door window glass 5 and the holder 6 is directly hit by water when driving at high speed in rainy weather, the contact area of the holder 6 is large, and the holder 6 remains flexible and close to the door window glass 5. Because of this, it can exhibit a high sealing effect.

In addition, the holder 6 is attached to the U-shaped portion 3CK4a of the retainer 3.
M, so taker 3 as shown in Figure 9.10.
Compared to the case where the tip of the holder 6 is simply folded back, peeling of the holder 6 becomes more difficult because the material of the holder 6 is folded into the U-shaped portion 3C.

By the way, as shown in FIG. 4, the retainer 3 has the same cross-section from the front end to the rear end, and is bent into a U-shape at the center after the holder 6 is glued. However,
When performing this bending process, it is necessary to prevent the U-shaped portion 3C from swinging in the direction of the arrow, using the inner guide 8 and the outer guide 9, as shown in FIG.

As shown in Figures 9 and 10, tighten the tip of the retainer 3 by a single Kt.
ff-! D In the case of the returned product, the lower edge of the holder 6 is extended to ensure a margin for adhesion of the holder 6, so the inner guide 8 has no choice but to come into contact with the lid 6. As a result, Due to the nature of the holder 6, which is an elastic material, the retainer 3 was allowed to fall in the direction of the arrow, but in this embodiment, the third
As shown in the figure, the 7-rank part 3b stands up substantially perpendicularly to the mounting surface 38, and the 7-rank part 3b can be reliably suppressed by the inner guide 8 and the outer guide 9, so the flange part 3b of the retainer 3 However, the dimensional accuracy can be ensured without causing the retainer 3 to fall down during the bending process.This invention is not limited to the above-mentioned embodiments, and for example, as a holder, as shown in FIG. A sub-lip 6C is added to the lip 6a as shown in FIG. 6, a sub-lip 6d is added in a V-shape to the lip 61 as shown in FIG. In addition to the lip 6a, a sub-lip 6e made of soft sponge is provided to absorb water that has entered between the lip 6a and the door window glass 5, and as shown in FIG. 6f may be formed so that water that has entered between the lip 6a and the door window glass 6f can be drained from the notch 6f.

In the above embodiments, the case where the present invention is applied to a stubbleless door window has been described, but the present invention can also be applied to stubbleless windows such as rear side windows and back windows.

As described in detail, according to the present invention, it is possible to reliably prevent the window panel from moving in the suction direction when the vehicle is traveling at high speed, and the window panel can also vibrate and generate a banging sound when the vehicle is traveling on rough roads. It has the effect of preventing

In addition, the holder is attached to the U-shaped part at the tip of the 7-rank part of the retainer, so the holder does not have to be turned into the U-shaped part, which increases the reliability of the holder's installation. be.
