An adjustable hinge for doors and windows, comprising: a) two hinge bodies (11, 12) for attaching respectively to the door frame (13) and door leaf (14); b) a revolving pin (15) suitable for mutually articulating the hinge bodies (11, 12); c) means (17) for adjusting the mutual positions of the two hinge bodies (11, 12) in a direction (Z) crosswise to the axis of the pin. The adjustment means (17) comprise a sleeve (20), axially associated with the pin (15), defining an external lateral coupling surface (20b) with a corresponding housing (22) defined in a first (11) of said hinge bodies (11, 12). The sleeve (20) is pivotally engaged with the housing (22) so that, while remaining constantly in contact with the walls (22a, 22b) of the cavity (22) during any rotation to change its position, it can occupy substantially any position required along a limited length of the crosswise adjustment direction (Z). Reversible locking means (25) are provided for locking the sleeve (20) in the positions it can occupy inside the housing (20) by means of a thrusting action in a defined locking direction (0). The sleeve (20) comprises at least three distinct portions (20b) of contact with the walls of the housing (22) spaced angularly with respect to one another. When the locking means (25) are in action, at least two of said distinct portions (20b) exert a thrusting force, in directions incident to one another, on respective parts (22a, 22b) of said walls so as to take up any slack in the coupling between the sleeve (20) and the housing (22) in directions incident to one another. |
