ABSTRACT:
A venetian blind slat-tilting mechanism including a pair of top-mounted bars to which tilt strings are attached at opposed positions and which are attached together through a nut threaded to a rod. The rod is connected to a pulley which is turned by a tilt-adjusting cord. The motion of the pulley turns the rod and moves the nut laterally, thus moving both bars and tilting the blind's slats. Additionally a slat-lifting mechanism is provided in the form of lift strings running over support pulleys to raise and lower the blind.
