Field of Industrial Application) The present invention relates to a novel lifting device. More specifically, it is an object of the present invention to provide a lifting device that uses a wire as a driving force transmitting means for lifting a lifting body, and that requires a small installation space, particularly a small surface area. To do.

(B. Overview of the Invention) In the lifting device of the present invention, the drive wire is arranged so as to extend over both sides of a plate-shaped guide member that is long in the up-down direction when viewed from the front for guiding the lift body. The drive wire and the lifting body are connected to each other on one surface side, and the drive force is applied to the drive wire on the other surface side of the guide member, thereby reducing the planar size of the device and installing the device. It does not require a space with a large area.

(C. Prior Art) [FIGS. 8 and 9] There are various kinds of lifting devices, for example, lifting devices for moving up and down window glass for automobiles, in which a wire is used as a driving body. There is.

8 and 9 show an example of an elevating device using a wire as a driving body.

Reference numeral a is a guide rail that extends in the vertical direction and is slightly curved when viewed from the side. Reference numeral b is a bracket, which is slidably supported by the guide rail a.

c is a guide reel rotatably supported on the front side of the upper end of the guide rail a, and d is a guide block fixed on the front side of the lower end of the guide rail a.

Reference numeral e is a drive unit, and a drive reel g is rotatably supported by a support plate f.

h and i are guide pipes for guiding the drive wire, h is connected between the upper end of the guide rail a and the support plate f, and i is supported by the lower end of the guide rail a. It is connected to the plate f.

j is a drive wire, which extends along the longitudinal direction of the guide rail a and is wound around the guide reel c at its upper end and then inserted into the guide pipe h and wound around the drive reel g several times, It is inserted into the pipe i, wound around the guide block d, and then passed through a path extending upward. The bracket b is connected at a portion located between the guide reel c and the guide block d.

In the lifting device, however, the drive reel g
When is rotated, the drive wire j is moved along the path. Therefore, the drive wire j is raised or lowered in the portion along the longitudinal direction of the guide rail a according to the rotation direction of the drive reel g, and thus the bracket b connected to this drive wire j is As a result, the member to be lifted or lowered is lifted or lowered, and the lifted member such as the window glass supported by the bracket b is lifted or lowered.

(D. Problems to be Solved by the Invention) [FIGS. 8 and 9]
[FIG.] In the above-described conventional lifting device, since the drive portion e is located on the side of the guide rail a, there is a problem that it cannot be arranged unless the area is large when viewed from the front.
