Description

[Detailed Description of the Invention] This invention relates to a window glass elevating device equipped with a slider adapted for elevating and lowering operations.

BACKGROUND OF THE INVENTION Window glasses for automobiles and the like are made to be able to slide along guide rails installed on the door body by connecting a bracket to the lower part and attaching a slider to the bracket.

In order to move the bracket, a separate mechanism for lifting and lowering the window glass is provided within the door body.

Now, when sliding the window glass up and down, there are two parts inside the door body.
~Three sets of guide rails are provided, and a slider is fitted to each set, but in order to ensure smooth sliding work, the fitting parts of the bracket and slider, and the slider and guide rail, have appropriate shapes. Alternatively, it is formed with play.

That is, one set of guide rails and the slider fitted thereto are used as a reference sliding part, and the sliders fitted to the guide rails of other sets work in accordance with the reference sliding part.

For this purpose, an appropriate shape or clearance is required.

Regarding the structure of the fitting part between the slider and guide rail,
There is a device disclosed in Japanese Utility Model Application Publication No. 49-22617, in which the slider can swing on a plane perpendicular to the mounting pin. It is shaped so that it can swing around the center, increasing its degree of freedom.

Although the present invention may be constructed with such a structure for a reference sliding part, its advantages will be most fully demonstrated if it is applied to other sets of sliding parts that operate in an accommodating manner.

Next, the structure will be explained with reference to embodiments shown in the drawings.

The window glass 1 and the bracket 2 are connected by inserting a bolt 3 into the upper part of the bracket 2 and attaching the window glass 1 to the bolt 3 through a pad 4.
is attached, and a retaining nut 6 is screwed in with a washer 5 via a pad 4 to connect them.

A mounting pin γ is implanted in the lower part of the bracket 2, and a contact plate 8 is formed at the end of the mounting pin γ.

The slider 9 is loosely fitted onto the mounting pin γ and is held between the bracket 2 and the contact plate 8.

The slider 9 is adapted to slide along a guide rail 10.

The mounting hole 9a of the slider 9, which loosely fits into the mounting pin γ, is
It is formed into a conical shape that expands from the central portion 9b toward both open ends 9c.

The fitting groove 9d of the slider 9 that fits into the guide rail 10 is formed to form an arc R on a plane perpendicular to the axis X-X of the mounting pin γ.

Further, a slider 9 facing the bracket 2 and the contact plate 8
A cylindrical bulge 9f is formed on the contact surface 9e of the mounting pin γ, with the horizontal axis y-y perpendicular to the axis XX of the mounting pin γ being the upper center.

Then, vibration isolating pieces 9g are provided above and below the cylindrical bulge 9f, that is, from the upper end to the lower end of the slider 9, and the ends 9h of the vibration isolating pieces 9g are always in contact with the bracket 2 and the abutting plate 8. It is formed so that it touches.

The slider 9 loosely fits into the mounting pin 7, the fitting groove 9d fits into the guide rail 10, and the cylindrical bulge 9f fits into the bracket 2.
Since it comes into contact with the plate 8 and the plate 8, it is necessary that the vibration isolating piece 9g itself be a bearing member.
The end portion 9h is also formed so as to come into contact with the bottom of the bracket 2 and the backing plate 8, and needs to be flexible enough to provide a vibration-proofing effect.

Therefore, the slider 9 may be formed by integrally molding the above-mentioned parts using a synthetic resin material such as Delrin.

As mentioned above, the slider 9 has a mounting hole 9 for the mounting pin I.
Since a has a conical shape toward both open ends 9c, it is loosely fitted to the mounting pin 7 so as to be swingable.

Since this oscillation mainly occurs in the vertical direction of the slider 9,
As shown in FIGS. 4 to 6, the mounting hole 9a is located at the central portion 9.
It may be formed in a tapered shape from b toward the opening end in the vertical direction, that is, the vertical direction, and the shape of the opening end may be in the shape of a long hole.

Alternatively, it may be formed as a long hole in the vertical direction passing through the mounting hole 9a.

Since the fitting groove 9d of the slider 9 with respect to the guide rail 10 is formed in the shape of an arc R, the slider 9 is fitted so as to be able to swing on a plane perpendicular to the axis x-x of the mounting pin γ.

Further, since a cylindrical bulge 9f is formed on the abutting surface 9e of the slider 90, it can swing about the horizontal axis y-y perpendicular to the axis x-x of the mounting pin I. .

Since the flexible vibration isolating piece 9g extending upward and downward of the cylindrical bulging portion 9f is formed so as to always come into contact with the bracket 2 and the backing plate 8, the cylindrical bulging portion 9f The part 9f receives the swinging movement about the axis y-y,
The slider 9 can be held at an appropriate position.

Since the present invention is intercepted and operated in this way, each slider fits easily into the plurality of guide rails, and the sliding operation is performed while adapting to the ascending and descending locus of the window glass.

Therefore, it is possible to prevent the window glass from being damaged during the lifting and lowering operations, and also to support the window glass via the slider so that it does not wobble.
