A door or window frame hinge comprises two hinge parts (10, 12) each having a bush (14, 18) and a flap (16, 20). A first bush (14) has a cylindrical cavity (24) with a sleeve (28) wherein a pin is fitted (22). A second bush (18) has a transversely elongated cavity (26) parallel to a plane of the door or window frame, and a lateral hole (56) for communication with the exterior of the cavity (26). The pin (22) engages the cavity (26) of the second bush (18) with clearance. A threaded diametral hole (54) of the pin (22) is engaged by at least one threaded grub screw (48; 49, 51) transversely, whereby to adjust its position with respect to the second bush (18), the opposite ends (48a, 48b, 49a, 51a) of the grub screw abut against opposite faces (50) of the cavity (26) in correspondence with the lateral hole (56). The adjustment means (48; 49, 50) have at least one formation (58; 59, 61) engageable by means of a manipulation tool (T) inserted from the outside through the lateral hole (56) of the second bush part (18). |
