ABSTRACT:
Assembly composed of a number of devices for rolling up/rolling down shading. On a side higher up, the said shading is immovably fastened to a frame and is wound onto or unwound from a tube from the bottom. Rotation of the tube is achieved by via a transmission device that can be slid along a vertical shaft. The vertical shaft is also the drive shaft. The transmission device is provided with clutches, so that on reaching the end positions when the drive shaft slips the transmission device can be brought to a standstill.
