Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window glass for raising and lowering an automobile, particularly,
The present invention relates to a window glass shake prevention device disposed in a window glass guide device without a door sash.

Generally, in a hard-top automobile 1 as shown in FIG. 1, the door 2 is not provided with a sash for guiding the window glass 3 up and down. Therefore, as shown in FIGS. 2 to 4, a guide rail 4 is disposed inside the door 2 in the moving direction of the window glass 3, and the guide rail 4 is fitted to the lower end of the window glass 3. The sliding guide 5 (two sliding guides 5 are provided in the figure) is attached to the back plate 6.
The guide rail 4 and the sliding guide 5 guide the window glass 3 which is raised and lowered via the regulator 7. However, the gap between the sliding guide 5 and the guide rail 4 is set large for reasons of parts manufacturing precision and assembly work, so that there is sufficient play when the vehicle is running. Window glass 3 vibrates and rattles. Therefore, conventionally, the back plate 6
An elastic body 8 such as rubber is fixed to the window glass, and the elastic body 8 is pressed to the outside of the guide rail 4 so that the inside side wall of the sliding guide 5 is pressed against the guide rail 4. There is one equipped with a shake prevention device 9 of No. 3. In addition, in FIG. 2, 10 is a vehicle body panel that houses the window glass 3, for example, the door 2,
This stabilizer is provided at the upper end of the outer panel and supports the window glass 3 on the inside and outside of the car.

However, in the case of such a conventional anti-shake device 9, when driving at high speed with the window glass 3 closed,
As shown in Figure 3.97, Volume 13, Page 98 (Published on August 20th), the airflow outside the vehicle causes damage to the 3rd part of the window glass.
Negative pressure sucked outward acts, and the lower end of the window glass 3 is moved toward the inside of the car using the stabilizer 10 as a fulcrum.
In other words, although the vehicle moves in the direction of the guide rail 4, since the elastic body 8 is disposed on the outside of the guide rail 4 as described above, the elastic body 8 is compressed and deformed. Therefore, the window glass 3 easily shakes due to the suction force during the traveling, and seal leakage occurs at the peripheral edge of the window glass 3, causing wind noise and the like.

Further, an adjustment bolt 11 is provided on the mounting portion 5a of the sliding guide 5 (the sliding guide 5 located at the lower position in this figure) to the back plate 6, and by adjusting the adjustment bolt 11, the window can be opened. The assembly of the glass 3 is adjusted. Therefore, when trying to prevent the window glass 3 from shaking during driving using the adjuster bolt 11 described above, the adjuster bolt 11 must be adjusted so that the upper end of the window glass 3 is inclined toward the inside of the vehicle. ,in this case,
Since the back plate 6 and the guide rail 4 are moved away from each other, the elastic body 8 is moved away from the guide rail 4 as shown in FIG.

Therefore, the force with which the elastic body 8 presses the guide rail 4 decreases, or the elastic body 8 separates from the guide rail 4, thereby preventing the vibration prevention device 9 from functioning sufficiently. The problem was that I couldn't do it anymore.

The present invention has been made in view of such conventional problems, and by pressing an elastic body from the inside of the guide rail to prevent rattling, a sliding guide made of an inelastic body is moved to the guide rail. The window glass is brought into contact with the outside of the vehicle, and the suction force acting on the window glass during driving is received between the sliding guide and the guide rail, thereby preventing the window glass from swinging. The present invention provides an anti-shake device for automobile window glass.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In explaining this embodiment, the same reference numerals are given to the same components as those in the conventional structure, and redundant explanations will be omitted.

That is, as shown in FIGS. 6 to 8, the shake prevention device 20 of the present invention includes a substantially U-shaped bracket 2 to which an elastic body 21 such as rubber is fixed to the inside of the substantially central portion.
2 is provided, and this bracket 22 is connected to the guide rail 4.
The elastic body 2 is arranged so as to straddle it from inside the vehicle.
1 is arranged so as to abut on the inside of the guide rail 4.

On the other hand, mounting flanges 22a, 22a are formed at both ends of the bracket 22, and these flanges 22a, 22a are made of an inelastic material such as metal or hard synthetic resin, and are attached to the guide rail 4 with play. It is fixed to the sliding guide 5 to be fitted using an adjustment bolt 11. At this time, by adjusting the lengths of the bent portions on both sides of the U-shaped bracket 22, when the bracket 22 is fixed to the sliding guide 5, the elastic body 21 can be attached to the guide rail. 4 is pressed with a predetermined force, that is, a force that allows relative movement between the sliding guide 5 and the guide rail 4 while preventing rattling therebetween.

With the above configuration, in the automobile window glass shake prevention device 20 of this embodiment, the sliding guide 5
An elastic body 21 is provided integrally with the window glass 3 and presses the inner side of the guide rail 4 to prevent the window glass 3 from rattling. The moving guide element 5 is closely attached to the outside of the vehicle of the guide rail 4. Therefore, as the sliding guide 5 made of an inelastic material is brought into contact with the outside of the vehicle of the guide rail 4, the lower end of the window glass 3 is prevented from moving toward the inside of the vehicle as shown in FIG. The stabilizer 10 shown in FIG. 1 and the sliding guide 5 are rigidly supported at two points.

For this reason, when the upper part of the window glass 3 that closes the door window is about to be sucked out to the outside of the vehicle due to the negative pressure generated by the airflow during driving, the window glass 3 that is housed in the door panel The lower end of the window glass 3 is about to be moved in the direction of the guide rail 4 (inside the vehicle) using the stabilizer 10 as a fulcrum. This can be reliably blocked by the guide rail 4 via the guide rail 4. Therefore, since the lower end of the window glass can be prevented from moving in this way, the upper part of the window glass 3, that is, the part that closes the door window can be prevented from swinging toward the outside of the vehicle. can.

Furthermore, in this embodiment, the bracket 22 to which the elastic body 21 is fixed is brought into contact with the sliding guide 5 by the adjusting bolt 11, so that the contact between the elastic body 21 and the inner edge of the sliding guide 5 on the outside of the vehicle is The distance remains constant regardless of how the adjuster bolt 11 is adjusted. Therefore, even if the distance between the back plate 6 and the guide rail 4 is adjusted by the adjusting bolt 11 when the window glass 3 is assembled, the sliding guide 5 and the elastic body 21 are always in close contact with the guide rail 4. , it is possible to prevent rattling or shaking of the window glass 3.

As explained above, the vehicle window glass shake prevention device of the present invention includes a stabilizer that is provided at the upper end of the vehicle body panel that houses the window glass, supports the inside and outside of the window glass, and the lower end of the window glass. In an automobile window structure, the structure includes a sliding guide made of an inelastic material provided at the lower end of the window glass, and a guide rail that fits into the sliding guide and guides the raising and lowering of the window glass. At the same time, the elastic body is pressed and brought into contact with the inside of the guide rail, and the urging force of the elastic body causes the sliding guide to come into contact with the outside of the guide rail. Not only does the pressing force of the elastic body eliminate looseness between the sliding guide and the guide rail, allowing the window glass to open and close smoothly, but it also guides the sliding guide made of an inelastic body. Since the rail can be kept in contact with the outside of the vehicle at all times, the movement of the lower end of the window glass toward the inside of the vehicle can be rigidly supported by the stabilizer and the sliding guide. can.

Therefore, when the upper part of the window glass is inclined outward using the stabilizer as a fulcrum due to negative pressure during high-speed driving, the lower end of the window glass is supported by the two rigid support parts of the vehicle. Since inward movement is reliably prevented, it is possible to prevent the window glass from swinging, thereby maintaining the sealing properties of the window glass periphery and preventing the generation of wind noise. can do.

Furthermore, by integrally attaching the elastic body to the sliding guide, even when adjusting the adjustment mechanism, the sliding guide and the elastic body move together while maintaining a predetermined distance. The sliding guide and the elastic body can be kept in close contact with the guide rail at all times. Therefore, no matter what adjustment the adjuster mechanism makes, various excellent effects are achieved in that the window glass shake prevention function can be reliably exhibited.
