Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a window regulator for opening and closing a sliding door type window.

``Prior Art'' Conventionally, when opening and closing a sliding door type window, a window regulator has been proposed in which the upper part of the sliding door is slidably supported and hangs down, and a geared cable is connected to the upper part to open and close the sliding door ( Jitsukai 57-181880
(see publication).

However, when only the upper part of the sliding door is pushed or pulled, the operating load is biased toward the upper part, and the lower part may become stuck, which may result in a lack of smooth operation.

Therefore, as shown in FIG. 3, it has been considered to connect a geared cable to the lower part of the window glass G to drive the top and bottom. Drive gear 4
If an attempt is made to drive the geared cables 1 and 2 by engaging them on both sides, the operating directions of the geared cables 1 and 2 will be reversed. The geared cable 2 must be guided to the drive unit 3, and the arrangement of the reversing rollers 5, 6 or the geared cable 2 is not only complicated, but also takes up space and has a low degree of freedom in arrangement. It was hot.

The present invention was created by focusing on these conventional problems, and allows two geared cables to be placed in parallel with a minimum amount of space, providing a high degree of freedom in placement. The purpose of this project is to provide a window regulator.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is that in a window regulator for opening and closing a sliding door type window, a guide tube is provided at the top and bottom of the window glass, and a guide tube is installed inside the window regulator. A sliding geared cable is installed,
Each geared cable is connected to the upper end and lower end of the window glass, both geared cables are extended in parallel in the same direction near the drive part, and a pair of drive gears arranged in parallel and meshed with each other is attached to the drive part. The window regulator is characterized in that both geared cables are meshed with each other, and a drive source is connected to one of the drive gears.

"Function" Accordingly, the geared cables are made to move in the same direction from the drive part by the drive gears arranged in parallel, and can be arranged in parallel.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 and 2 show an embodiment of the present invention, and the window regulator 10 is constructed as follows.

Outer cylinders 10a, 20a are disposed above and below the window glass G in the same direction, and the outer cylinders 10a, 20a
are extended to the drive section 30 in parallel.

A geared cable 1 is installed inside the outer cylinders 10a and 20a.
1 and 21 are internally movable vertically, their distal ends are connected to the upper and lower ends of the window glass G, respectively, and their proximal ends extend into the drive section 30 inside the outer cylinders 10a and 20a.

The drive unit 30 includes drive gears 32 and 33 that mesh with each other and are supported side by side on a base 31, a worm 34 that meshes with one of the drive gears 33, and a motor 35 that rotates the worm 34.
is provided.

The geared cable 11 is meshed with a drive gear 32, and the geared cable 21 is meshed with a drive gear 33.

In the window regulator having the above configuration, when the worm 34 is rotated by the motor 35, the drive gear 33 is rotationally driven, and the drive gear 32 meshing with the drive gear 33 rotates in the opposite direction to this drive gear 33. .

As a result, the geared cable 1 is meshed with the drive gears 32 and 33 by the drive of the motor 35.
1 and 21 are pushed and pulled in the same direction and move vertically at the same speed, and are also pushed and pulled in the same direction and at the same speed in the upper and lower positions of the window glass G, so that the window glass G is opened and closed smoothly.

"Effects of the invention" According to the window regulator 10 according to the invention, since the top and bottom of the window glass G are driven, the opening/closing operation is smooth. By meshing each geared cable with its corresponding geared cable, the geared cables can be placed in parallel, which saves space and reduces the thickness near the drive unit, allowing for a high degree of freedom in placement within a thin door. can do.
