Device for rolling up/rolling down a shade

摘要

Assembly composed of a number of devices for rolling up/rolling down shading. On a side higher up, 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 means of a transmission device that can be slid along a vertical shaft. Said 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.
