OPERATING DEVICE FOR DOORS AND WINDOWS

Abstract

A door and window operating device is described herein, comprising a box-shaped body (2); a wheel (3) having a first circular extension (3a) having a smooth surface and a second circular extension (3b) which is toothed and housed within the box-shaped body (2); a rod (8) which is slidably inserted into the box-shaped body (2) and which has relative ends outside the box-shaped body (2), configured to be connected, when in use, to movable opening / closing devices of a sash (1) which are located on the sash (1); the rod (8) having a relative surface equipped with an operating rail (9) which meshes with the second circular toothed extension (3b) of the wheel (3) in such a way as to allow, upon rotation of the wheel (3), sliding of the rod (8) which, then and starting from a closed position of the leaf (1) in a fixed frame,can assume a first opening position of the leaf (1) from the fixed frame and a second, open position of the leaf (1) relative to the fixed frame, different from the previous one; a sliding element (10) for selecting and locking the wheel (3) which can be firmly inserted into the box-shaped body (2) through a first through seat (11) present in the box-shaped body (2); the sliding element (10) is capable of being positioned radially relative to the wheel (3) and in a manner that interferes with the rotation of the wheel (3) by forming an abutment with a first projection of the toothing (12) of one end of the second toothed circular extension (3b), thus limiting the rotation of the wheel (3) only between the closed position of the leaf (1) and a single open position of the leaf (1) and vice versa.,
