1. A hinge assembly for windows of the tilt-and-turn type, comprising a lower hinge body (1) to be fixed to a window frame (2) and a upper hinge body (3) to be fixed to the mobile portion (4) of the window as well as a hinge pin (5) engaging with respective hub portions (1a, 3a) of said lower and upper hinge bodies. The hub portion (3a) of upper hinge body (3) have a circular axial seat (9) for pivotally engaging a corresponding cylindrical portion (5a) of said pin. The pin comprises a shaped portion (5b) engaging with said hub portion (1a) of said lower hinge body (1) in a not rotatable way with respect to its own axis, but angularly displaceable therewithin on a plane containing said axis and perpendicular to the window plane. The pin further comprises an intermediate annular body (5c) acting as an abutment and placed between the shaped portion (5b) and the cylindrical portion (5a) and slidably abutting on a end of hub portion (1a) of the lower hinge body (1), the centre of rotation (C) of the angular displacement being located substantially at the other end thereof. <IMAGE> |
