Improvements in the mechanisms of operation in blinds of mobile slats, essentially characterized by the fact that the plates are advantageously provided with a square at their lateral ends, which are articulated to a fixed frame and at least those from a side to a handrail or movable rail, with the particularity that this rail is also articulated, by means of a connecting rod, to the free end of a radial finger belonging to a cylindrical toothed sector that meshes with an endless screw axially fixed to a conical gear, which receives the movement from a pinion also conical having axially secured a handle suitable for the maneuver, so that with the rotation of the sector toothed is obtained the displacement of the handrail and with it the rotation of the slats around their fixed joints, achieving the opening or closing of the same according to the direction in which the handlebar is turned.
