Abstract

[Objective] [0001] The present invention relates to a shoe for a carriage of a window regulator which has enhanced the anti-shake function of a glass window and improved durability.

[Configuration] Carrying of window regulator in which low-elastic, tough sliding contact materials (3, 5) are inserted into the left and right sides and the front and rear of the shoe (1) mounted on the back of the carriage in a window regulator for a hard top type automobile. Jishu shoe.

Description

Carriage shoe of window regulator

In the so-called electric car door that opens and closes the glass window by the power of the motor, a window regulator is mounted. The window regulator has a sedan type and a hard top type according to the body style. The sedan consists of a carriage and a slider associated with it, which moves up and down along the rail with the rails enclosing the rail, while the hard top type allows the slider to replace the shoe on the C rail and move up and down the rail. Two shoes are installed at the upper and lower ends of the carriage, one each.

The carriage shoe of the hard top window regulator is a synthetic resin molded article, which has a circular shape and a flexible wing with convex protruding contact portions on both inner sides of the C-rail. However, the wing-type shoe is difficult to assemble the elastic material to support the inside, and the elasticity is weak, often over time when the window is opened and closed properly. In addition, it was noted that noise was generated, and the wings were worn out within a short time.

On the other hand, since the circular shoe makes point contact with weak bearing force until it slides on the inner surface of the C-shaped rail, the attitude of the carriage on the rail is unstable.

Early wear of the sliding contact could not be avoided.

The present invention improves the problems of the carriage shoe of the conventional window regulator as described above. By inserting sliding contact material made of small, tough synthetic rubber etc. and inserting it into the rail forcibly, it can effectively cope with premature wear of the rail contact part and at the same time, it ensures the stability of the carriage not to fluctuate in the left and right directions as well as the front and rear directions when the carriage moves up and down. It was pursued.

1 and 2, in the synthetic resin molded article, the shaft hole 2 is formed in the surface center of the shoe 1 serving as the main body, and the sliding contact material 3 is implanted in both sides of the shoe 1. These sliding contact materials 3 are made of a low elastic rubber, a low elastic rubber, a synthetic rubber, a synthetic resin, and have a band shape. The contact surface of the sliding contact material 3 is provided with a point or a single linear contact protrusion 4 such as a long linear or third degree of curved surface extending in the width direction to make contact with the inner surface of the rail. The sliding contact material 3 is implanted into the shoe 1 main body. That is, injection molding is carried out so that the root portion is embedded in the sliding contact material 3 or by inserting the shoe 1 into the root contact of the sliding contact material 3 by injection molding. The sliding contact material 5 as described above is also implanted side by side in two rows on the front and rear surfaces of the shoe 1. In any sliding contact material (3) (5), the insertion direction must all follow the lifting direction of the carriage.

FIG. 4 shows the mounting position of the shoe 1 with respect to the carriage 6 and the state fitted to the C-shaped rail 7, and FIG. 5 is a diagram traversing the shoe 1 portion. The assembly sequence is as follows. First, the shaft 8 is inserted from the rear of the shaft hole 2 to the front and then inserted into the shaft hole 9 of the carriage 6 previously drilled, and the tip of the shaft 8 protrudes to the opposite side of the shaft hole 9. Fasten the nut to the rail and slide it toward the end of the rail (7).

The width of the shoe 1 including the sliding contact material 3 is slightly larger than the dimension between the inner surfaces of the rail 7, and the thickness of the shoe 1 including the sliding contact material 5 is in front of the inner surface of the rail 7. Slightly larger than the later dimension. However, since the sliding contact materials 3 and 5 are elastic bodies, they can be forcibly fitted to the rail 7. In this way, after the shoe 1 is forcibly fitted to the rail 7, the shoe 1 does not swing in the rail 7 in the lateral direction as well as in the front and rear directions. As a result, the carriage and even the windshield stabilize the posture on the rail.

As described above, the carriage shoe of the window regulator of the present invention has a low elasticity, a low elasticity, and a strong synthetic rubber at the left and right sides of the shoe that contact the inner surface of the rail and the part that will contact the front and rear of the inner surface of the rail at the front and rear of the shoe. It is made by inserting a sliding contact material made of a material, etc., the sliding contact material, which is a rail contacting part, has a proper elasticity, but is materially strong and has long mechanical life, The stability of the posture is very unlikely that the carriage will swing back and forth as well as from side to side as the carriage moves up and down the rails. Therefore, the window opening and closing operation is quiet and smooth.

The present invention relates to a carriage shoe for a window regulator to be applied to a hard top type vehicle body, and more particularly to a carriage shoe for a window regulator that improves the durability and the durability of a windshield preventing function.
