Abstract

A device (10) for moving members for operating or for closing a window or door frame, of the type activated by the rotation of the pin (14) of a lever or a handle (15) and comprising a supporting and containing body (11) of a mechanism (12) for transforming the rotary motion of an element (13) intended to be coupled with the pin (14) of a control lever or handle (15) in translational motion of at least one slider (16, 16'), wherein the supporting and containing body (11) is houseable in a seat (101, 201, 301) of a profile (100, 200, 300) constituting a side of a window or door frame movable swing and wherein the at least one slider (16, 16') is coupleable with a respective rod for operating or closing the movable swing, and that is characterised in that it comprises an auxiliary body (19) that is mounted on the supporting and containing body (11) in a mutually movable manner along a direction (D) that, when the moving device (10) is in the mounted configuration on the profile (100, 200, 300), is parallel to the side of the profile of the swing and orthogonal to the direction (R) of the translational motion of the at least one slider (16), wherein the auxiliary body (19) is provided with at least one abutment element (20) with a reference plane (106, 206, 306) defined in the profile and adapted to serve as reference for the positioning of the supporting and containing body (11) in the seat (101, 201, 301) along the direction (D) and adjustment means (21) for the adjustment of the relative position of the auxiliary body (19) and of the supporting and containing body (11) along the direction (D).
