A clutch-controlled hinge for pivot door and window frames (1) comprising a fixed frame (2) and a mobile frame (3) which can rotate about an axis of rotation (X) consists of two half-bodies (5, 6) attached to the fixed frame (2) and the mobile frame (3), with a pin (7) - seat (8) unit for rotation of the mobile frame (3) about the axis (X); each clutch-controlled hinge (4) is equipped with adjustable means (9) for clutch-control of the mobile frame (3) during rotation and means (10) for stably positioning the mobile frame (3), starting from a position in which the door or window frame (1) is closed, between a position in which it is open, with the mobile frame (3) turned at an angle ( alpha ) to the fixed frame (2), and a service position, in which the mobile frame (3) is turned at a straight angle to the fixed frame (2); the stable positioning means (10) are positioned and operate along the axis of rotation (X) and comprise reciprocal connecting parts (11) attached to the respective fixed and mobile half-bodies (5, 6) to allow movement and positioning of the mobile frame (3) between the closed position and the open position and vice versa; there are also cam means (12) on the pin (7), which act upon the connecting means (11) in such a way as to allow the mobile frame (3) to pass from the open position to the service position and vice versa. <IMAGE> |
