An adjustable hinge comprising: a) two hinge bodies for attaching respectively to a window or door frame and a window or door leaf; b) a revolving pin suitable for mutually articulating the hinge bodies; c) a member for adjusting shared positions of the hinge bodies in a direction generally perpendicular to the axis of the pin. The adjustment member includes a sleeve, associated axially with the pin, defining an external lateral coupling surface with a corresponding housing defined in a first of the hinge bodies. The sleeve is pivotally engaged with the housing-such that, while remaining in relatively constant contact with the walls of the cavity during any rotation to change its position, it may occupy substantially any position required along a limited length of the perpendicular adjustment direction. A reversible locking member is also provided for locking the sleeve in positions it occupies inside the housing upon a thrusting action in a defined or selected locking direction. The sleeve has at least three distinct points of contact with the walls of the housing spaced angularly relative to one another. When the locking member is in action, at least two of the distinct points exert a thrusting force, in directions incident to one another, on respective points of the walls so as to accommodate for slack upon coupling between the sleeve and housing in directions generally incident to one another. |
