Improved cremone for doors and windows, essentially characterized in that it is constituted by a lever articulated on a guide box, which has eccentrically articulated and in two opposite zones of its extension opposing pins arranged in combination with a laminar spring that impinges at its ends on said pins retaining them in their opening and closing positions, given by the actuation of the lever that produces the reversible rectilinear displacements of said pins, which, at their ends, have lateral projections that receive the coupling of the rods destined to penetrate the fittings. Of the frame of the doors and windows that include the latter. (Machine-translation by Google Translate, not legally binding)
