A door or window frame comprises: a fixed frame (2) and a sash (3) hinged to one another along a stile (4); transmission means (5) designed to allow the movement of contact and/or closing elements (7), to define, in conjunction with fixed connecting elements (8) positioned on the fixed frame (2), door or window frame (1) closed, turned opened and tilted open configurations; a handle (10) acting on the transmission means (5) to determine, through rotation of its handgrip (11), the closed and open configurations, corresponding to three stable positions of the handgrip (11); sealing means (12) associated along the sash (3) and, in the closed configuration, positioned in contact with the fixed frame (2); an auxiliary connecting element (13), associated with the fixed frame (3) and acting on a sash (3) closing element (7a); activation/deactivation means (14) acting on the auxiliary element (13) allowing, in its activation configuration, guided interception of the closing element (7a), in one of the opening positions and alternatively to them, thus distancing the sealing means (12) from the fixed frame (2) with relative partial opening of the door or window frame (1) seal. |
