BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of the present invention applied to a window regulator of a front door of a passenger car. FIG. 1 is a front view of a window regulator according to an embodiment of the present invention viewed from the outside of a vehicle.
Is a rear view in FIG. 1, FIG. 3 is a view in the direction of arrow B in FIG. 1,
FIG. 4 is a cross-sectional view taken along section line CC in FIG.

In these figures, reference numeral 21 denotes a base plate attached to the door panel. First and second pins 22, 24 are rotatably provided on the base plate 21, and the proximal ends of the first and second lift arms 26, 28 are attached to these pins 22, 24. ing.

A pinion 32, which is rotationally driven by a motor 30 integrally provided with a speed reducing mechanism having a braking action such as a worm and a worm wheel, is provided between the first and second pins 22 and 24. It is arranged.

On the other hand, a sector gear 34 meshing with the pinion 32 is fixed to the first lift arm 26, and a sector gear 36 meshing with the pinion 32 is fixed to the second lift arm 28, respectively.

Therefore, the motor 30, the pinion 32,
Sector gear 34 fixed to first lift arm 26
And the sector gear 3 fixed to the second lift arm 28
6 constitute a drive source, and when the motor 30 is rotationally driven, the first and second lift arms 26 and 28 rotate in the same direction.

In the present embodiment, as shown in FIG. 3, when the first and second lift arms 26, 28 rotate, the first and second lift arms 26, 28 prevent the first and second lift arms 26, 28 from interfering with the pinion gear 32. An intermediate portion between the second lift arms 26 and 28 is bent in a direction away from the pinion gear 32.

Reference numeral 40 denotes glass runs 42 and 44,
The door glass is guided in an ascending / descending (opening / closing) direction (the direction of arrow D in FIG. 1). A lift arm bracket 50 is attached to a lower portion of the door glass 40 via a glass holder 100 and extends in a direction substantially perpendicular to the direction in which the door glass 40 moves up and down. The cross-sectional shape of the lift arm bracket 50 is, as shown in FIG. 4, an upright wall 51 parallel to the door glass 40, and a top portion bent from the upper and lower ends of the upright wall 51 and extending away from the door glass 40. 52, bottom 53
And bent portions 54 and 55 that are bent from the top portions 52 and the distal ends of the bottom portion 53 and extend toward each other. A slit 56 is formed between the bent portion 54 and the bent portion 55. Is formed.

In the lift arm bracket 50, the first
And the second sliders 61 and 62 are movably engaged. The tip of the first lift arm 26 is rotatably attached to the first slider 61 using a pin 65, and the tip of the second lift arm 28 is attached to the second slider 62 using a pin 66. The side is rotatably mounted.

Therefore, the base plate 21, the first lift arm 26, the lift arm bracket 50, and the second lift arm 28 constitute a link mechanism. In the present embodiment, the base plate 21
The inner end is locked by a slot 24 a formed on the second pin 24, and the outer end is locked by a cut-and-raised portion 21 a formed on the base plate 21, via a second lift arm 28. A balance spring 70 that urges the door glass 40 in the upward direction and reduces the load on the motor 30 is provided.

Next, the operation of the above configuration will be described. When the motor 30 is driven, the pinion 32 rotates. As a result, the first lift arm 26 having the sector gear 34 meshing with the pinion 32 moves around the first pin 22,
The second lift arms 28 having the sector gears 36 meshing with the pinions 32 rotate in the same direction about the second pins 24, respectively. The rotation of the first and second lift arms 26 and 28 causes the lift arm bracket 50 to rotate.
Door glass 40 attached to the glass run 42,
It goes up and down along 44.

According to the above-structured window regulator, the driving force of the motor 30 is controlled by the first lift arm 26,
Since it works in a distributed manner with the second lift arm 28,
The durability of the first lift arm 26 and the durability of the second lift arm 28 are substantially the same, and the durability can be improved as compared with the conventional example.

Further, the adjustment of the standing of the door glass 40 can be easily performed because only the adjustment of the base plate 21 is required. Further, since the driving force of the motor 30 is dispersed and acts on the first lift arm 26 and the second lift arm 28, the deflection amounts of the first and second lift arms 26 and 28 should be substantially matched. And the door glass 40 can be moved up and down smoothly.

Further, the first and second sliders 61 and 62 movably engaged with the lift arm bracket 50 are provided.
Move in the same direction, the lift arm bracket 50 can be shortened, and the mounting space is reduced.

Further, as compared with the conventional window regulator, the conventional window regulator has a welding operation for integrating the equalizer arms in the assembling process, whereas the window regulator of the present embodiment is different from the conventional window regulator. The assembly of the regulator can all be performed by mechanical connection such as caulking, and automation of the assembly can be easily performed.

The present invention is not limited to the above embodiment. In the above embodiment, the power window regulator using the motor 30 has been described, but it is needless to say that the present invention can be applied to a manual window regulator.

In the above-described embodiment, the window regulator for the front door is used. However, as shown in FIG. 2, the distance L1 from the first pin 22 to the pin 65 of the first lift arm 26, By changing the distance L2 from the second pin 24 to the pin 66 of the second lift arm 28, the door glass 40 can move up and down with rotation, and can be applied to a rear quarter window and the like.

Further, although the balance spring 70 is provided on the second pin 24, it may be provided on the first pin 22,
Furthermore, it is not necessary to provide a balance spring.

[0038]

As described above, according to the present invention, the driving force of the driving source is distributed and acts on the first lift arm and the second lift arm. The durability with the second lift arm is almost the same,
The durability can be improved as compared with the conventional example.

The adjustment of the mounting of the glass can be easily performed because only the adjustment of the base plate is required. Since the driving force of the driving source is distributed and acts on the first lift arm and the second lift arm, the deflection amounts of the first and second lift arms can be substantially matched, and smooth glass Movement becomes possible.

Since the first and second sliders move in the same direction, the lift arm bracket can be shortened, and the mounting space is reduced.
