[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire type window regulator device for raising and lowering a window glass of an automobile.

[0002]

2. Description of the Related Art Conventionally, a carrier plate for transferring a window glass is arranged outside a guide rail so as to be movable in the vertical direction, and a sliding body for engaging the guide rail is provided on the carrier plate, and a longitudinal direction of the guide rail is also provided. A rotary drum around which a wire is wound is rotatably provided near the center, and pulleys for vertically guiding the wire from the rotary drum are rotatably provided near the upper end and the lower end of the guide rail. 2. Description of the Related Art There is known a window regulator device in which both ends of a wire guide rail are connected to a plate connecting body along a longitudinal direction thereof.

[0003]

However, in the conventional window regulator device, when the window glass is moved up and down with respect to the guide rail, it is not possible to maintain an equilibrium state in which the sliding body moves upward and downward with respect to the guide rail. There is a risk of rattling against the rail, and the sliding body slides in the vertical direction while engaging with the guide rail together with the carrier plate. Could not be performed smoothly in a stable state.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by rotating a rotary drum so that the wire causes the wire to rotate with the annular groove of the first guide roller and the second guide roller. While moving while engaging with the annular groove of the roller, the first pulley and the second pulley rotate in the same direction with respect to the side portions near the one end and the other end of the support body as the wire moves. The first guide roller and the second
While the guide roller of is rotating, the wire slides vertically along the guide rail by the wire, and the carrier plate moves to the first position.
Together with the first guide roller and the second guide roller, the window glass moves up and down along the guide rail, and the window glass moves up and down along the longitudinal direction of the guide rail together with the carrier plate. The locking body and the second locking body lock both ends of the wire along the longitudinal direction of the guide rail to both ends of the support body,
The upper and lower equilibrium states of the first guide roller and the second guide roller with respect to the guide rail are adjusted by the wire between the first pulley and the first locking body and the second pulley and the second pulley.
It is kept by a wire between the guide rail of the carrier plate and the guide rail of the carrier plate, and the sliding resistance of the guide rails of the first guide roller and the second guide roller is small. An object of the present invention is to provide a window regulator device that can be smoothly moved up and down by a first guide roller and a second guide roller in a stable state.

[0005]

In the window regulator device of the present invention, a carrier plate for transferring the window glass is movably arranged on the outer side of the guide rail and vertically movable on the inner side of the guide rail. A support body is arranged along the carrier plate, and first and second guide rollers for raising and lowering that engage with the guide rails are rotatably provided on the carrier plate. A base plate is disposed laterally of the guide rail, a rotary drum having a wire wound around the base plate is rotatably provided, and the wire is wound around the outer circumferences of the first and second guide rollers. Grooves are respectively formed, and the wire from the rotary drum is guided toward the annular groove of the first guide roller at a side portion near one end of the support body. A first pulley rotatably disposed that,
A second pulley, which guides the wire from the rotary drum toward the annular groove of the second guide roller, is rotatably provided on a side portion of the support near the other end, and the guide rail of the wire is provided. The first and second locking bodies that lock with both ends of the support body are fixed to both ends along the longitudinal direction of the above.

[0006]

When the rotating drum provided on the inner base plate near the center in the longitudinal direction of the support disposed along the longitudinal direction inside the guide rail is rotated, the wire wound around the rotating drum rotates the rotating drum. Along with the movement of the support body, the support plate moves outside while engaging with the annular grooves formed on the outer circumferences of the first and second guide rollers provided on the carrier plate disposed on the outer side of the guide rail. First provided in the section
And the second pulley rotate in the same direction as the wire moves, and the first guide roller and the second pulley
While the guide roller of is rotating, the wire slides vertically along the guide rail by the wire, and the carrier plate moves to the first position.
Together with the guide roller and the second guide roller, the window glass moves up and down along with the carrier plate along the longitudinal direction of the guide rail.

Further, when the window glass is moved up and down with respect to the guide rail, the first locking body and the second locking body fixed to both ends of the wire along the longitudinal direction of the guide rail connect both ends of the wire to both ends of the support body. The wire between the first pulley and the first locking body and the wire between the second pulley and the second locking body are locked to the first guide roller and the second guide roller. Maintain an upward and downward equilibrium with the guide rails.
