The present invention relates to a window glass raising / lowering device in which a drive cable is routed, and a carrier plate slidably fitted to the guide rail and fixed to the window glass is fixed to the drive cable.

"Prior Art" As a conventional window glass lifting device, for example,
There is one disclosed in Japanese Patent Laid-Open No. 195474.

That is, in the publication, a pair of guide rails are arranged in parallel along the ascending / descending path of the window glass, and pulleys for guiding the drive cables are arranged above and below the guide rails. The drive cables are provided at four locations. Wrap the pulleys in a Z-shape one after another, extend both ends of the drive cable to the drive section, and fit the guide plates to both guide rails so that the carrier plates can be slidably fitted, and the drive cables can be fixed to both carrier plates. What has been done is disclosed.

[Problems to be Solved by the Invention] However, in such a conventional technique, since the drive cable as a whole extends long from one end to the other, the extension of the cable is in the direction in which the height of the carrier plate is deviated. However, since the parallelism of the window glass when moving up and down is likely to change, and the complicated configuration with one cable routed around, it is complicated to adjust the position of the carrier plate. It was

The present invention has been made in view of such conventional problems, and it is a window of a thin and rational structure in which the drive cable does not easily extend and the carrier plates of the respective guide rails are less likely to be displaced. It is intended to provide a glass lifting device.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is that a pair of guide rails arranged in parallel along the ascending / descending trajectory of a window glass is integrally fixed by a connecting bracket. Then, a drive cable is routed along the guide rail, and a carrier plate for slidably fitting the guide rail and fixed to the window glass is fixed to the drive cable. In the above, guide members for guiding the drive cable in parallel with the window glass surface are respectively arranged at the upper and lower ends of the pair of guide rails, and a separate system is formed for the upper and lower guide members of each guide rail. Drive cable of each system, and the drive cables of each system are wound together and rotated so as to be fed out, and a pair of cables having a rotation center axis substantially parallel to the window glass surface is wound on the winding drum. A window glass characterized in that a cable feeding / unloading member having the above is arranged in the connection bracket, and a drive unit is provided for rotating the cable winding drum of the cable feeding / unwinding member or for moving the drive cable in the vertical direction. It exists in the lifting device.

"Operation" When the drive cable is input to the drive section and the drive cable of either system is moved vertically by manual or power, the cable winding drum is rotated and one end of the drive cable of the other system is fed in and out. The member is wound around the cable winding drum, and the other end side is paid out.

The drive cables of the respective systems move vertically between the guide members at the upper and lower ends of the corresponding guide rails, whereby the carrier plates also move up and down and the window glass opens and closes.

Since the drive cable is divided into two systems, it is difficult to stretch,
Even if it extends, it appears in almost the same proportion to the carrier plate, so the posture of the window glass does not change.

In the case where the cable winding drum is directly driven to rotate, one end side of each of the drive cables of both systems is wound and the other end side is fed out by the rotation of the cable winding drum. Drive cables vertically move between the upper and lower guide members of the corresponding guide rails, and the carrier plates move up and down to open and close the window glass.
