CURTAIN LEDGE TUBE

摘要

The tube is designed for curtains and screens. It ensures continuous and even movement of the curtains and screens, their even distribution at rest and remote shifting using a mechanism for moving the rod loops. The mechanism consists of an inner tube (2) resting by bearings (3) to an external tube (1) with a slit along the whole upper part of the ledge. Between the two tubes a screw-type spiral (4) with windings having different pitches is fitted which is fixed to the external tube (2) and loops (8). Each of the loops (8) has a pin to the centre located between the spiral windings (4) and in the slit of the external tube (1). The mechanism also contains a pulley for shifting (5) having a cord wound around it to start the movement (6)./!
