Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable type window regulator, and particularly when it has a drive shaft and a driven shaft, the overall thickness of the device is reduced, the degree of freedom in the shape of the door inner panel is increased, and parts are provided. The present invention relates to improvements in the structure of the balance spring, drum arrangement, and driven shaft that can reduce the number of points.

[Prior art]

A cable type window regulator has been proposed which opens and closes an automobile door window with a cable. (See, for example, Japanese Utility Model Laid-Open Nos. 58-114376, 58-62770, and 64-11277). This cable type window regulator
Generally provided between the door inner panel and the door window is, for example, a drive shaft (drive shaft) to which a regulator handle is attached, a drive gear attached to the drive shaft, and a driven shaft arranged in parallel with the drive shaft. The driven shaft is mainly composed of a driven shaft, a driven gear that is mounted on the driven shaft and meshes with a drive gear, and a drum that is mounted inside the driven gear of the driven shaft and that winds or unwinds a cable. A balance spring is attached to the drive shaft on the side of the drive gear.

[0003]

In the conventional regulator described above, since the balance spring is mounted on the outer side in the axial direction of the drive gear, the thickness of the entire regulator is increased. Therefore, the curvature of the door window surface is set. There may be a restriction on the vehicle interior, or the dimensions in the vehicle may be sacrificed when trying to secure a sufficient gap with the door window.

In the conventional regulator, the drum is arranged closer to the door inner panel inside the vehicle than the driven gear as described above. Therefore, there is a problem that the outlet of the cable approaches the door inner panel and the shape of the panel is restricted.

Further, in the conventional regulator, since the driven shaft is provided separately and independently, the number of parts is increased and the cost is increased.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to secure a sufficient gap between the apparatus and the door window by making the entire apparatus thinner, or the degree of freedom in the shape of the door inner panel. It is an object of the present invention to provide a cable type window regulator that can be expanded or cost can be reduced by reducing the number of parts.

[0007]

According to a first aspect of the present invention, in a cable type window regulator for opening and closing a door window with a cable, a drive shaft is provided with a drive gear, and a driven shaft provided in parallel with the drive shaft. In addition to mounting a driven gear that meshes with the drive gear, a drum for winding or unwinding the cable on the driven shaft, and a balance spring mounted inside the drive gear.

According to a second aspect of the present invention, in a cable type window regulator for opening and closing a door window with a cable, a drive gear is mounted on a drive shaft, and the drive gear is mounted on a driven shaft arranged below the drive shaft. It is characterized in that a driven gear that meshes with is mounted and a drum for winding or unwinding the cable is provided on the door window side of the driven shaft.

According to a third aspect of the present invention, in a cable type window regulator for opening and closing a door window by a cable, a drive gear and a driven gear that meshes with the drive gear are provided in a resin case, and the cable is wound or unwound. The driven shaft supporting the drum and the driven gear is integrally formed with the resin case.

[0010]

In the invention of claim 1, since the balance spring is mounted inside the drive gear, it is possible to make the regulator as a whole thinner. As a result, a sufficient gap can be secured between the door window and the door window without restricting the curvature of the door window surface and without sacrificing the width of the vehicle.

According to the second aspect of the invention, since the drum is provided on the door window side of the driven shaft, the cable outlet of the drum is separated from the door inner panel, and the shape of the door inner panel is restricted by the outlet portion. And the flexibility of the shape of the door inner panel can be expanded.

Further, according to the third aspect of the invention, since the driven shaft supporting the drum and the driven gear is integrally formed with the resin case, the number of parts can be reduced, and thus the cost can be reduced.

Further, the window regulator 1 has a drive shaft 5, the door window side end portion 5b of the drive shaft 5 is rotatably supported by a boss portion 4a formed integrally with the case 4, and the inside end portion of the vehicle is the above. The base plate 3, the door inner panel 6 and the trim 7 are inserted to extend inside the vehicle. A pinion 5a is formed at the tip of the drive shaft 5, and a regulator handle 9 having a knob 8 is attached to the pinion 5a.

A drive gear 10 is attached to the drive shaft 5. A brake spring 10c for applying a braking force is mounted around the boss portion 10a of the drive gear 10. A recess 10b is formed on the end surface of the drive gear 10 on the opposite side to the boss 10a side. The recess 10b is provided to apply a load to the rotation of the driven gear 10 when the door window 2 is opened. The balance spring 14 is attached.

A boss portion (driven shaft) 4b protruding inward of the vehicle is integrally formed on the lower portion of the resin case 4. A driven gear 12 that meshes with the drive gear 10 is mounted on the driven shaft 4b.
A drum 20 for winding or unwinding the cable 21 is attached to the driven shaft 4b.

On the other hand, a supporting portion 25 (FIG. 1) for supporting the door window 2 is fixed to the lower portion of the door window 2. The supporting portion 25 is slidably attached to a guide rail 26 arranged in the vertical direction. Rotatable pulleys 27 and 28 are provided at the upper and lower ends of the guide rail 26. In addition, the case 2 has a cable 2
Outlet ports 30 and 31 for taking out 1 are provided. The cable 21 passes through the outer tubes 32, 33 from the respective outlets 30, 31, and the pulleys 27, 28.
It is wound around the guide rail 26 and is vertically arranged in the guide rail 26, and the support portion 25 is locked to a part of the cable 21 in the guide rail 26. Also,
As shown in FIG. 1, the two outlets 30 and 31 are arranged in a V shape which makes an angle with each other toward the guide rail 26. As a result, the cable 21 can be easily routed from the window regulator 1 to the pulleys 27 and 28.
