DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window regulator device for a vehicle for raising and lowering a window glass.

[0002]

2. Description of the Related Art Conventionally, as this type of window regulator device, one disclosed in Japanese Utility Model Laid-Open No. 2-129585 is known.

[0003] This includes a guide rail, a carrier bracket that moves up and down along the guide rail, and a pair of shoes fixed to the carrier bracket and slidably supported by the guide rail and opposed to each other in the vertical direction of the carrier bracket. The carrier bracket is moved by a drive mechanism via a wire, whereby the carrier bracket moves up and down along the guide rail through sliding of the shoe and the guide rail, thereby fixing the carrier bracket. As a result, the window formed in the door is opened and closed.

[0004]

In the above-mentioned conventional apparatus, grease is usually applied to the guide rail in order to smoothly slide the shoe and the guide rail.
When the carrier bracket is raised and lowered, the grease applied by the shower is swept up and down in the vertical direction, and as a result, the grease does not work effectively, causing problems such as heavy lifting and lowering of the carrier bracket. I feared.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make sure that grease always effectively acts on sliding between a shoe and a guide rail when the carrier bracket is moved up and down.

[0006]

The technical means taken in the present invention to solve the above technical problem is a guide rail, a carrier bracket that moves up and down along the guide rail, and is fixed to the carrier bracket. A pair of shoes slidably supported by the guide rails and opposed to each other in the vertical direction of the carrier bracket;
A closed space defined by the carrier bracket and the pair of shoes and containing grease that is closed by the guide rail and can be applied to the guide rail;
A through hole formed in the carrier bracket and communicating with the closed space.

[0007]

According to the above technical means, grease is supplied to the guide rail from the closed space by moving up and down along the guide rail of the carrier bracket. Therefore, even if grease is swept up and down by sliding between the guide and the guide rail, new grease is applied to the guide rail, and the slide between the shoe and the guide rail is required when the carrier bracket is raised and lowered. Grease can always work effectively on movement.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a wind regulator device 1 is provided in a door 2 of a vehicle, and moves a window glass 4 up and down. The window glass 4 is attached to the door frame 3 fixed to the door 2.
May be slidably supported and move up and down along the door frame 3 by the operation of the window regulator device 1 (see FIG. 2), or only through the window regulator device 1 without using the door frame 3. The window regulator may be slidably supported by the door 2 and move up and down along a guide rail 11 to be described later of the window regulator 1 by the operation of the window regulator 1 (a so-called hard top car).

[0010] The wind regulator device 1 is shown in FIG.
As shown in FIG. 2, it is composed of a guide rail 11, a drive mechanism 12, a pair of upper and lower pulleys 13 and 14, and a carrier bracket 15.

The guide rail 11 is fixed to a panel constituting the door 2 so as to extend in the vertical direction of the door. The drive mechanism 12 is composed of a drum 12a rotatably supported by a panel, and a wire 12b fixed at both ends to the drum 12a and wound around the drum 12a. Have been.
The upper and lower pulleys 13 and 14 are respectively formed by bracket portions 11 a and 1 formed at upper and lower ends of the guide rail 11 so as to extend laterally.
The wires 12b are supported rotatably, and the wires 12b are stretched. The carrier bracket 15 is fixed to the window glass 4, and is fixed to the wire 12b between the upper and lower pulleys 13 and 14 by a well-known fixing structure 16 (shown in FIG. 2) composed of a piece and a guide. The carrier bracket 15 is supported by the guide rail 11 via a pair of shoes 17 and 18 to be described later so as to move up and down along the guide rail 11.

In the above configuration, when the drum 12a is driven to rotate in one direction, the wire 12b moves in one direction and the carrier bracket 15 descends along the guide rail 11. Thereby, the window glass 4 descends and the window opens. When the drum 12a is rotated in the other direction, the wire 12b moves in the other direction, and the carrier bracket 15 moves up along the guide rail 11. Thereby, the window glass 4 rises and the window is closed. The rotation of the drum 12a is performed by a motor or an operation handle (not shown) connected to the drum 12a.

As shown in FIGS. 2 and 3, the guide rail 11 has a U-shaped cross section having flanges 11c formed at both ends and bent inward. The pair of shoes 17 and 18 is a carrier bracket 1
5 so that they face each other in the vertical direction (guide rail 1
1 and are integrally fixed to the carrier bracket 15 by outsert molding or the like. The pair of shoes 17 and 18 are disposed within the cross-sectional shape of the guide rail 11 so as to be prevented from falling off by the flange 11b, and slide on the guide rail 11 of the carrier bracket 15 as the guide rail 11 moves up and down. It is slidably supported by the guide rail 11. As a result, the carrier bracket 15 is supported by the guide rail 11 so as to move up and down along the guide rail 11.

Guide rail 1 of carrier bracket 15
The surface 15a on one side and the opposing surface 17 of the shoes 17, 18
The space A is defined by a and 18a. This space A is closed by sliding surfaces, which are the inner surfaces 11d on both sides of the guide rail 11 and the inner surface 11e on the bottom wall. Grease applied to the guide rail 11 is accommodated in the space A. Thus, the space A in which grease is stored
Is composed of the existing components of the window regulator device 1, so that the number of components does not increase, and the number of assembly steps, weight and cost are advantageous. Further, a through hole 19 communicating with the space A is formed in the carrier bracket 15, and grease is injected into the space A through the through hole 19. Therefore, grease can be injected into the space A in the final step after assembling the wind regulator device 1, and the assembling work becomes easier.

In the above configuration, when the carrier bracket 15 is moved up and down along the guide rail 11, the grease contained in the space A is reduced to the surface 1 of the shews 17 and 18.
The guide rails 7a and 18a press the guide rails 11 and the sliding surfaces between the guides 17 and 18 (mainly, inner surfaces 11d of both side walls of the guide rails 11). Therefore, each time the carrier bracket 15 is moved up and down, new grease is applied to the guide rail 11, and the grease is always applied to slide the guide rails 11 between the shoes 17 and 18 when the carrier bracket 15 is moved up and down. Works effectively. As a result, smooth operation of the carrier bracket 15 is always ensured.

[0016]

According to the present invention, since a closed space for accommodating grease that can be applied to the guide rail is defined in the carrier bracket, grease is supplied from the closed space to the guide rail by raising and lowering the carrier bracket along the guide rail. The grease can always effectively act on the sliding between the shoe and the guide rail when the carrier bracket is moved up and down. Further, since the closed space is defined by the carrier bracket and the pair of shoes, the closed space is defined by the existing components of the window regulator device itself, and the components are used when defining the closed space. There is no increase in the number of points, and the number of assembling steps, weight, cost, and the like can be improved. Furthermore, since a through-hole communicating with the closed space is formed in the carrier bracket, grease can be injected into the closed space in the final process after assembling the wind regulator device itself, which hinders assembly work at all. And the injection operation can be facilitated.
