An upper cross member (1) fixable to a wall or a ceiling carries the panel (6, 6 min ) and the control cords (8) pass over rollers housed in this cross member and are wound onto a reel (10) which is connected rigidly for rotation with a sprocket (11) on which engages a closed loop of chain (12). This sprocket (11) and reel (10) are rotatably supported in a housing (13) fixable to the said upper cross member (1) and provided with means for locking the movement of the chain (12) in the direction of lowering of the blind panel (6, 6 min ).</p> |
