Adjustable hinge

An adjustable hinge comprising:

• a plurality of hinge bodies for attachment to a fixed frame and to a mobile frame, respectively, of a door or window,
• a revolving pin for pivotally connecting the hinge bodies to one another, and
• a member for adjusting shared positions of the hinge bodies in a direction generally perpendicular to the axis of the pin, the adjustment member comprising a sleeve, associated axially with the pin, defining an external lateral surface for coupling with a corresponding housing defined in a first of the hinge bodies, the sleeve being pivotal inside the housing such that, while it remains in relatively constant contact with the walls of the housing during its rotation to change position, it may occupy substantially any position required along a limited length of the perpendicular adjustment direction a reversible locking member being provided for locking the sleeve in the positions it occupies inside the housing upon application of a thrusting force in a selected locking direction, wherein the sleeve has at least three distinct portions of contact with the walls of the housing, spaced angularly from one another, and when the locking member is engaged, at at least two of the distinct contact points a thrusting force is exerted, in directions incident to one another, on respective portions of the walls so as to accommodate for slack between the sleeve and the housing in incident directions, wherein the first hinge body corresponds to the upper hinge body, the sleeve being mounted coaxially to the upper part of the pin, the perpendicular adjustment direction being substantially parallel to the plane of the mobile frame to which the hinge is attached with the aid of a mounting member, the hinge further comprising a second member for adjusting the shared positions of the two hinge bodies in a direction substantially orthogonal to the plane of the mobile frame to which the hinge is attached, the second member being independent of the parallel adjustment member, and wherein the second adjustment member comprises a cylindrical cavity, passing through the lower hinge body, along an axis lying generally parallel to the axis of the pin, and inside the cylindrical cavity a sleeve is housed having a vertically extending through hole therein, which, in turn, contains a bushing that houses pivotally and concentrically the lower part of the revolving pin, the bushing housing the pin being mounted eccentrically relative to the sleeve, the lower opening of the through hole in the sleeve being shaped for coupling with a wrench suitable for inducing the rotation of the sleeve.

• wherein the sleeve has at least three distinct portions of contact with the walls of the housing, spaced angularly from one another, and when the locking member is engaged, at at least two of the distinct contact points a thrusting force is exerted, in directions incident to one another, on respective portions of the walls so as to accommodate for slack between the sleeve and the housing in incident directions, wherein the third member for vertical hinge adjustment comprises a relatively small counter-threaded cylinder engaged with a threaded internal lower portion of the sleeve through hole, a bushing with the pin resting against the counter-threaded small cylinder.
