Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a curtain driving device disposed on a wall, ceiling, etc. of a building.

[Prior Art] In a conventional curtain driving device, a curtain rail is provided only at the upper edge of a window opening, and the upper end edge of the curtain is connected to and suspended from the curtain rail, and the curtain is hung from the curtain rail. The window can be opened and closed by moving it along the window.

[Problems to be Solved by the Invention] However, in such conventional curtains, only the upper edge of the curtain was connected to the curtain rail, and the lower edge was free, which caused the curtain to be blown away by the wind. This poses a problem in that it impairs the light shielding effect and is difficult to install on inclined surfaces or ceiling surfaces.

[Means for Solving the Problem] In order to solve this problem, the second invention provides a frame having a substantially U-shaped cross section and a rectangular annular shape, and the inside of each corner of the frame has a substantially U-shaped cross section. A pulley body having a pair of pulleys is disposed in each of the pulley bodies, a drive motor is connected to one of the pulley bodies to form a drive pulley body, and a pair of drive pulleys are connected to each of the pair of drive pulleys of the drive pulley body. A ring-shaped wire is wound around one pair of pulleys of each pulley body of the pond, with one end wound in an open manner and the other wire wound in a cross manner. One end edge of the curtain was connected to one side of one of the wires, and the other end edge of the curtain was connected to the pond side opposite to the one side of the other wire of the pair of wires. It is characterized by a curtain driving device.

Further, the pair of wires can also be made to cross each other at both sides other than the curtain connecting portion.

[Function] According to this means, when a pair of drive pulleys of the drive pulley body are driven by one drive motor, both drive pulleys rotate in the same direction, but each of these drive pulleys has a Because the wires are wound open or cross-wound, both wires move in opposite directions. Therefore, one side of one wire and the side of the other wire move in the same direction. As a result, since both end edges of the curtain are connected to this one side and the other side, the both end edges move in the same direction, and the curtain can be opened and closed at once.

In this way, since both ends of the curtain are connected to both wires, the curtain will not be blown away by the wind like in the past, and the light shielding effect will be sufficient. It is also possible to install it on the ceiling.
The range of use will expand.

Further, since the curtain can be opened and closed using one drive motor, it is possible to provide a curtain drive device with a simple configuration.
