ABSTRACT:
A tilt mechanism for monocontrol Venetian blinds uses band brakes to the ends of which the ladder cords are attached. The weight of the blind provides the tightening forces to cause the band brakes to grip the rotating control rod and rotate the slats to open and close the blind. Stops loosen the band brakes allowing further rotation for raising or lowering of the blind to take place with a minimum of torque.
