(57) A door or window frame (1) 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), closed and turned open configurations;
a handle (10) acting on the transmission means (5) to determine, through rotation
of its handgrip (11), the closed and turned open configurations, corresponding to
at least two stable positions of the handgrip (11); an auxiliary connecting element
(13), associated with the fixed frame (2) and acting on a closing element (7a) when
the handgrip (11) moves into a third stable operating position allowing guided interception
of the closing element (7a) by the auxiliary element (13) in such a way as to space
the sash (3) from the fixed frame (2) to a limited extent in order to at least partly
break the seal of the frame (1).
