A hinge provided with adjustable friction to prevent the free rotation of the hinged rigid structures, comprising two bodies (1, 7) provided respectively with substantially cylindrical cavities (1', 7') wherein a shaped pin (4) is slidably inserted being axially shiftable by adjusting means (2, 3) so as to elastically deform friction means (5) interposed between said pin (4) and the wall of cavity (1') of the first body, and thus generate the desired friction between the hinged parts, the inner cavity (7') of the second body (7) being provided with ribs slidable into the grooves of pin (4). With said hinge it is also possible to adjust the friction so as to continuously pass from the condition wherein the rotation of the hinged parts is free to the condition in which the hinge is substantially blocked. <IMAGE> |
