Description

  The present invention relates to an X-arm type window regulator that raises and lowers a vehicle window glass.

A general X-arm type window regulator for a vehicle is configured such that a lift arm and an equalizer arm intersect with each other in an X shape at an intermediate portion thereof and are pivotally attached, and a driven gear is attached to one end of the lift arm.
A roller or slider is attached to one end of the equalizer arm, and this roller or slider is slidably engaged with a fixed guide channel attached to the door along a substantially horizontal direction.
Rollers or sliders are mounted on the other end of the lift arm and the other end of the equalizer arm, respectively, and these rollers or sliders are slidably engaged with a lifting guide channel mounted along the lower end of the window glass. Yes.

The driven gear fixed to one end of the lift arm meshes with a drive mechanism installed on the door, and when the drive mechanism is operated, the lift arm rotates up and down.
Then, the equalizer arm pivotally attached to the lift arm also rotates up and down around one end engaged with the fixed guide channel, and the lift guide channel engaged with the other end of the lift arm and the other end of the equalizer arm is changed. Go up and down.
As a result, the window glass supported by the lifting guide channel moves up and down.

By the way, when the window regulator is mounted on the vehicle, the fixed guide channel and the lifting guide channel are attached to the door and the window glass, and then the rollers or sliders attached to the lift arm and the equalizer arm are engaged with these guide channels. Since it is narrow, installation work becomes very difficult.
Therefore, it is often the case that the rollers and sliders mounted on the lift arm and the equalizer arm are previously engaged with the lift guide channel and the fixed guide channel, which are conveyed to the vehicle and assembled.
However, simply engaging the roller or slider with the channel may cause the roller or slider to escape from the end of the channel during transport or assembly operations.

Therefore, a technique to fold a part of both ends of the channel material inward to make a roller stopper, and a technique to form a raised part to become a roller stopper on the inner surface of both ends when forming the channel material are proposed. (See Patent Document 1 and Patent Document 2).
However, these stoppers cannot be formed in one process simultaneously with the press molding or forming of the channel material, and there is a drawback that the manufacturing process of the channel material tends to be complicated. In addition, before bending both ends of the channel material, the channel material must be fitted with a roller. Before forming a raised portion at both ends of the channel material, a roller is provided at the middle portion of the channel material. An insertion opening for insertion had to be formed.

  An object of the present invention is to provide a window regulator in which a fixed guide channel and an elevating guide channel do not fall off from a lift arm and an equalizer arm and can be easily transported and attached.

  In the window regulator of the present invention, a lift arm and an equalizer arm are crossed and pivotally attached, a driven gear meshing with a drive mechanism is fixed to one end of the lift arm, and a roller or a slider attached to one end of the equalizer arm, A roller or a slider, which is engaged with a fixed guide channel so as to be movable in the axial direction, and is mounted on the other end of the lift arm and the other end of the equalizer arm, is moved in the axial direction to a lifting guide channel that supports the window glass. It is movably engaged, and an inclined piece is formed on the inner surfaces of both ends of the fixed guide channel and the lift guide channel by cutting and raising the tip so as to face the center in the longitudinal direction of these guide channels.

According to the present invention, since the inclined piece that prevents the roller or the slider from coming off is formed by cutting and raising, the guide channel can be formed in one process at the same time as the press molding or forming process, and the number of processes at the time of manufacture is reduced. Less is enough.
In addition, since the tip of the inclined piece faces the central portion in the longitudinal direction, the roller or slider can be inserted from the end face of the guide channel through the inclined piece, but the roller or slider is restricted by the tip of the inclined piece. It does not escape from the guide channel and is easy to transport and assemble.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The window regulator according to the present embodiment moves a window glass for a vehicle up and down, and includes a lift arm 1, an equalizer arm 2, a driven gear 3, a fixed guide channel 4, and a lift guide channel 5 as shown in FIG.
The lift arm 1 and the equalizer arm 2 intersect with each other at an intermediate portion thereof and are axially attached. A driven gear 3 is fixed to one end of the lift arm 1.
The driven gear 3 is driven by a drive mechanism 6 installed on the door of the vehicle body. The drive mechanism 6 has a motor 7 and a pinion 8 connected to the output shaft of the motor 7, and the driven gear 3 is engaged with the pinion 8.

A first roller 9 is rotatably mounted on the other end of the lift arm 1, and a second roller 10 and a third roller 11 are rotatably mounted on both ends of the equalizer arm 2, respectively. .
Then, the second roller 10 attached to one end of the equalizer arm 2 is engaged with the fixed guide channel 4 so as to be movable in the axial direction.
The first roller 9 attached to the other end of the lift arm 1 and the third roller 11 attached to the other end of the equalizer arm 2 are engaged with the lifting guide channel 5 so as to be movable in the axial direction. Has been.

The fixed guide channel 4 is attached to the door of the vehicle body along the front-rear direction, and the elevating guide channel 5 supports the lower end of the window glass 12.
Therefore, when the motor 7 is operated to rotate the pinion 8, the driven gear 3 meshed with the pinion 8 rotates, and the other end of the lift arm 1 fixed to the driven gear 3 rotates up and down. Then, the other end of the equalizer arm 2 pivotally attached to the lift arm 1 also rotates up and down. As a result, the raising / lowering guide channel 5 moves up and down, and the window glass 12 supported by the lifting guide channel 5 moves up and down. Further, as the elevating guide channel 5 moves up and down, the first roller 9 and the third roller 11 move along the elevating guide channel 5, and the second roller 10 moves along the fixed guide channel 4.
The above structure is the same as that of the conventional X arm type window regulator.

As shown in FIGS. 2 and 3, a through hole 13 is formed in both ends of the bottom surface of the fixed guide channel 4 and the lift guide channel 5, and the first is slightly closer to the center in the longitudinal direction than the through hole 13. In addition, an inclined piece 14 is formed to prevent the third rollers 9, 10, 11 from coming off.
The through hole 13 formed in the fixed guide channel 4 is for fixing the fixed guide channel 4 to the door, and the through hole 13 formed in the lift guide channel 5 is for attaching the window glass 12 to the lift guide channel 5. belongs to.

The inclined piece 14 is formed by cutting and raising the bottom surfaces of the guide channels 4 and 5 toward the inner surface side so that the tip faces the central portion in the longitudinal direction of the guide channels 4 and 5.
The inclined piece 14 is inclined so that the distance from the bottom surface of the guide channels 4 and 5 increases as the tip of the inclined piece 14 faces the center in the longitudinal direction and approaches the tip, so that even if the inclined piece 14 is formed, the guide The rollers 9, 10, 11 can be inserted from the open end faces of the channels 4, 5 and can be fitted through the inclined piece 14.
Further, it prevents the rollers 9, 10, 11 from escaping from the end surfaces of the guide channels 4, 5 when the tip of the inclined piece 14 hits the rollers 9, 10, 11. For this reason, the window regulator can be transported and incorporated in the automobile with the fixed guide channel 4 and the lifting guide channel 5 attached to the lift arm 1 and the equalizer arm 2.
In the present invention, instead of the first to third rollers 9, 10, and 11, a slider that can be slidably engaged with the fixed guide channel 4 and the lift guide channel 5 in the axial direction can be used.
