Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a window glass lifting device for driving the window glass up and down by a drive cable, and is used for automobile windows.

(Prior Art) Conventionally, as this type of elevating device, there is a technique disclosed in, for example, Japanese Utility Model Application Publication No. 17473/1983.

This technology provides a guide rail along the vertical trajectory of the window glass, routes the drive cable so that it can move vertically along the guide rail, and connects the drive cable to the window glass so that it can slide into the guide rail. The carrier plate is fixed to the drive cable, and the end of the drive cable is connected to the drive part through an outer tube, which automatically absorbs the permanent elongation of the drive cable and eliminates the weight of the window glass. A spiral spring is provided within the casing of the drive unit to bias the drive cable with balanced biasing forces.

(Problems to be Solved by the Invention) However, in such a conventional window glass lifting device, the thickness of the drive section becomes thick, and the entire lifting device becomes thick. When inserting and assembling the door into the space between the inner panel and the outer panel of the door, there was a problem that the assembling work was difficult and the workability was poor.

The present invention was developed by focusing on these conventional problems, and it improves the workability of assembling the device by making the entire device thinner, and also makes it possible to adjust the tension of the drive cable. The purpose of this invention is to provide a device for lifting and lowering window glass.

(Means for solving the problem) The gist of the present invention to achieve this purpose is as follows:
A guide rail is provided along the ascending and descending trajectory of the window glass, a drive cable is routed vertically movably along the guide rail, and a carrier plate is fixed to the window glass and slidably fitted to the guide rail. In a window glass lifting device that is fixed to the drive cable and in which the end of the drive cable is connected to the drive unit via an outer tube, the tension of the drive cable is adjusted by changing the relative position of the drive cable and the outer tube. A tension mechanism for adjusting the tension is provided in the drive part, and a plate part integrally fixed with the guide rail,
A balancer is provided that biases the drive cable with a biasing force balanced with the weight of the window glass, and the tension mechanism includes a holder that holds the outer tube, and a mounting plate to which the holder is integrally attached. The base plate of the drive unit and an adjustment member for adjusting the relative position of the mounting plate, the mounting plate is jointly fastened between the door inner panel and the base plate, and the holder is attached to the drive unit. The two ends of the outer tube, which respectively guide the incoming and outgoing drive cables, are fitted in the same direction.
The present invention relates to a window glass lifting device characterized by having a holding part and a second holding part.

(Function) In the above-mentioned window glass lifting device, the balancer is provided on a plate portion that is integrally fixed with the guide rail, so that the entire device is made thinner, and the tension mechanism allows the drive cable and the outer tube to be connected to each other. The amount of tension of the drive cable can be adjusted by changing the relative position with respect to the drive cable. The adjustment is made as follows. The attachment plate is made movable by loosening the joint fastened between the door inner panel and the base plate, and the attachment plate is moved by the adjustment member. The integral holder moves due to the movement of the mounting plate, and the first holding part and the second holding part move in the same direction, so that the two ends of the outer tube move forward and backward, and move relative to the drive cable. The amount of tension changes. Stop the mounting plate at an appropriate position, and then tighten and fix it between the door inner panel and the board as before.

1 and 12 are displaced relative to the drive cables 6 and 60. Therefore, the relative positions of the outer tubes 11, 12 and the drive cables 6, 60 change, and the tension of the drive cables 6, 60 can be adjusted appropriately.

(Effect of the invention) According to the window glass lifting device according to the present invention, a balancer that biases the drive cable with a biasing force balanced with the weight of the window glass is provided on the plate portion that is integrally fixed with the guide rail. Therefore, the entire lifting device can be made thinner, the workability of assembling the lifting device can be improved, and furthermore, the amount of tension of the drive cable can be appropriately adjusted by the tensioning mechanism provided in the drive section.

Furthermore, a holder integrated with the mounting plate of the tensioning mechanism is provided with a first holding part and a second holding part in which the two ends of the outer tube are fitted in the same direction, respectively, to connect the door inner panel and the drive part. Since they are jointly tightened with the board, by moving the mounting plate in the same direction, each drive cable going in and out of the drive unit can be adjusted at the same time, which improves the workability of adjustment and the assembly of the tensioning mechanism. Good workability.
