Abstract: Hinge for an opening door or window frame including a first and a second knuckle parts connected together by a pin, the arrangement being such as to allow adjustment between the first and second knuckle parts independently parallel to, and at right angles to, the general plane of the door or window. Adjustment parallel to the door or window is by means of a cam integral with the pin and engaged in the cavity of the first knuckle part. The cam and the cavity have surfaces of mutual contact formed in such a way that rotation of the causes a movement of relative translation only between the first and second knuckle parts.
