Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention prevents the windshields of automobiles, especially those of hard-top automobiles that do not have a window glass retainer, from being sucked out by negative pressure during high-speed driving. This invention relates to an anti-shake device for automobile window glass that prevents it from shaking due to vibration or the like.

(Prior Art) As a conventional automobile window glass shake prevention device, there is one shown in FIGS. 1 and 2, for example. (Refer to Japanese Utility Model Publication No. 57-32224.) In other words, the window glass G is held movable up and down by a lifting mechanism R provided in the door D, and the window glass shake prevention device 1 is mounted on the upper part of the inner panel 2. A first stabilizer 10 that engages with an engagement device 20 fixed to the stabilizer 10, and a second stabilizer that abuts the lower inner surface of a reinforcement 30 provided along the inner edge of the upper end of the outer panel 3 at a position below this stabilizer. The stabilizer 11 is provided, and the load applied to the window glass G in the outdoor direction is partially borne not only on the inner panel 2 side of the door D but also on the outer panel 3 side. Window glass G is necessary even if the rigidity of the glass is insufficient.
This ensures rigidity in the outdoor direction, thereby preventing the window glass from being sucked out by negative pressure during high-speed driving.

However, in such a conventional automobile window glass shake prevention device, the first stabilizer 1
0 and the second stabilizer 11 are provided to ensure rigidity in the outdoor direction, thereby preventing the window glass G from moving in the outdoor direction due to the negative pressure. Since sufficient consideration was not given to ensuring rigidity against directional loads, there was a problem in that it was not possible to sufficiently prevent the window glass G from rattling due to vibration or the like.

(Purpose of the invention) The present invention has been developed by focusing on these conventional problems, and uses an extremely simple structure to ensure the rigidity of the window glass in the outdoor direction and the indoor direction. The aim is to solve the above problems.

(Structure of the invention) The gist of the invention to achieve the above object is to provide a pair of guide rollers that can come into contact with both sides of the window glass, one of which is provided on the inner panel side and the other on the outer panel side, A stopper member is fixed to the lower end of the window glass, a pair of abutted parts are provided on the inner panel and the outer panel, and each abutted part of the inner panel and outer panel and each of the abutted parts of the stopper member at the lower end of the window glass are provided. A pair of guide surfaces inclined with respect to the glass surface of the window glass are provided on at least one of the parts opposite to the abutment part, and the other guide surface is provided with a pair of guide surfaces that are inclined with respect to the glass surface of the window glass. An apparatus for preventing vibration of a window glass for an automobile, characterized in that the inner panel and the outer panel are engaged with the pair of inclined guide surfaces to draw the inner panel and the outer panel toward the window glass, respectively, during the closing operation of the window glass.

When the window glass is fully closed, the other is engaged with the inclined guide surface provided on at least one of the abutted parts of the inner panel and the outer panel and the abutment part of the stopper member at the lower end of the window glass. The inner panel and outer panel are brought together toward the window glass to hold the lower end of the window glass so that it does not swing inward or outward.

(Example) An example of the present invention will be described below based on the drawings. Note that the same parts as in the conventional example are given the same reference numerals.

FIG. 3 and FIG. 4 show an embodiment of the present invention, and an automobile window glass shake prevention device 1 includes:
A first guide roller 4 and a second guide roller 5 are provided as a pair of guide rollers that can come into contact with both surfaces G1 and G2 of the window glass G.

The first bracket 6 is attached to the inner panel 2 of the door D.
is fixed to the support portion 61 of the second bracket 6,
A first arm 41 that pivotally supports the first guide roller 4 is fixed to the tip.

A reinforcement 30 fixed to the outer panel 3 of the door D has a second arm 51 fixed to the tip thereof with a second guide roller 5 pivotally supported thereon, and a second bracket 7 fixed thereto.

The first bracket 6 and the second bracket 7 have a first inclined guide part 62 and a second inclined guide part 72 as a pair of abutted parts extending obliquely downward toward both surfaces G1 and G2 of the window glass G, respectively. each formed.

A stopper member 8 is fixed to the lower end of the window glass G, and the stopper member 8 has a tapered surface 8 that can come into contact with the first and second inclined guide parts 62 and 72.
A contact portion 80 having numbers 1 and 82 is formed to expand upward.

The first and second brackets 6, 7 are operated when the window glass G is closed from near the fully closed position to the fully closed position.
The contact portion 80 of the stopper member 8 is formed at a position such that it comes into contact with the first and second inclined guide portions 62 and 72.

In the automobile window glass shake prevention device 1 having the above configuration, when the window glass G is open,
As shown in FIG. 4, even if the first and second guide rollers 4 and 5 are apart from both surfaces G1 and G2 of the window glass G, when the window glass G is raised, the problem occurs near the fully closed position. Tapered surface 8 of contact portion 80
1 and 82 begin to abut against the first and second inclined guide portions 62 and 72, which are abutted portions, as shown by the two-dot chain line in FIG.

When the window glass G is further raised from near the fully closed position to the fully closed position, the tapered surfaces 81 and 82 of the contact portion 80
pulls the first and second inclined guide portions 62 and 72, thereby drawing the inner panel 2, reinforcement 30, and outer panel 3 together, and as shown in FIG. 3, the first and second guide rollers 4, 5 is pressed against both surfaces G1 and G2 of the window glass G.

In this manner, when the window glass G is fully closed, the contact portion 80 of the stopper member 8 pulls the first and second inclined guide portions 62 and 72, thereby causing the first and second guide rollers 4 and 5 to move. Since the window glass G is firmly held by contacting both sides G1 and G2 of the window glass G, the load in the indoor direction A applied to the window glass G is applied not only to the inner panel 2 but also to the outer panel. 3 and the reinforcement 30, and the load in the outdoor direction B applied to the window glass G is borne not only by the outer panel 3 and the reinforcement 30 but also by the inner panel 2. I am making the department pay for it.

Therefore, the rigidity of the window glass G in the outdoor direction B and the rigidity in the indoor direction A are ensured, which prevents the window glass G from being sucked out by negative pressure during high-speed driving, and also prevents vibrations. This prevents the window glass G from rattling due to such factors.

According to the embodiment described above, the first and second inclined guide portions 62 and 72 also serve as stopper portions that restrict the raised position of the window glass G by restricting the raised position of the stopper member 8. In addition, although we have shown an example in which the tapered guide part for drawing both the inner and outer panels is formed on each of the abutted part and the abutting part, the guide part may be provided on either one of them. Good too.

(Effect of the invention) According to the device for preventing vibration of an automobile window glass according to the present invention, when the window glass is in a fully closed state, the contact parts of the inner panel and the outer panel come into contact with the stopper member on the window glass side. the other engages with an inclined guide surface provided on at least one of the parts;
The inner panel and outer panel are each drawn toward the window glass, and a pair of guide rollers are brought into contact with both sides of the window glass to firmly hold the window glass. The rigidity of the window and the rigidity in the direction of the interior are ensured, which prevents the window glass from being sucked out by negative pressure during high-speed driving, and also prevents the window glass from rattling due to vibrations and the like.
