Hinge for a door or window

A hinge for a door or window, which has a frame part and a leaf/casement part that are arrangeable in the frame and in the leaf/casement of the door or window, respectively, wherein the frame part has a fastening portion that is connected via a joint to a hinge flap extending substantially normally to the rabbet into a receptacle in the housing of the leaf/casement part, and wherein the penetration depth of the hinge flap in the leaf/casement part corresponds to a multiple of its thickness in the direction normal to the leaf/casement plane of the door or window, wherein, in order to fix the position of the hinge flap in the leaf/casement part, a damping part that is displaceable in the insertion direction of the hinge flap and is preloaded in the direction of the rabbet by means of a spring is provided, said clamping part being arranged beneath the receptacle for the hinge flap and having a guide portion and a damping portion projecting upwardly from the latter into the receptacle in the direction of the hinge flap, wherein, during the introduction of the hinge flap, the damping portion cooperates with the free end of the hinge flap and the clamping part is displaceable by said free end counter to the force of its spring, and wherein, after the hinge flap has been fully inserted and the leaf/casement part has been lowered into its locking position, in which a retaining protrusion arranged in the leaf/casement part comes to lie in a retaining recess of the hinge flap, the clamping part returns into its starting position and the clamping portion bears against the hinge flap at a lower end-face portion, with the result that the hinge flap is fixed in position.
