ABSTRACT:
Cabinet hinge whose door-related part in the form of a cup set in a mortise is articulated to the carcase-related part configured as an elongated supporting arm of inverted U-shaped cross section by two hinge links whose ends are journaled in the cup at one end and on the supporting arm at the other. A closing mechanism is provided in the door-end of the supporting arm and has a cam surface configured nonrotationally on the inner hinge link. A resiliently deformable section of one leg of a substantially U-shaped leaf spring engages the cam surface with bias, and the end remote from the cup of the other leg is fastened inside of the supporting arm by a section of the web of the latter. The inner hinge link has at the end by which it is mounted in the supporting arm two parallel ears formed by tabs cut and bent at right angles from the lateral margins of its end inside of the supporting arm. The cam surface is formed in the area of the bottom of the inner hinge link that is between the ears, and the resiliently springing leg of the leaf spring in contact with the cam surface is under a bias seeking to bring its free resilient end toward the second leg held in the supporting arm.
