Title: Operating devices and slats for reversible window blinds

Abstract: Improved operating devices for reversible blinds, in such a way that the movement of the latter is caused when the projections (8) of the slats (101) mesh into the two driving pinions (60) and (62), which move simultaneously thanks to two couples of transmission pinions (59) and (61) and intermediate wheels (63) and (64), reverting the hand operating device on the first transmission pinion (59) through a bevel wheel (58) moved by a bevel pinion (57), which is operated by means of a handle (52) through four separating pinions (56), while the motorized operating device reverts on the first transmission pinion (59) through a two stage reducing device of the planetary type and a motorization gear (78); having the slat hook (104) been modified to adapt to the inward cranked flange (107) which, in turn, occupies more than half of the width of the slat (101).
