ABSTRACT:
A tilt mechanism for venetian type blinds has a pair of straps and connecting cross bars which form a parallelogram. The front rails of the ladders are connected to one strap and the rear rails of the ladders are connected to the other strap. Movement of the straps toward one another moves the rails of the ladder toward one another and in opposite vertical directions and tilts the blind slats resting on the ladder.
