Abstract
An over-center hinge for cabinet doors with a door-related hinge part in the form of a recess-mounting cup in which one end of each of two links is journaled whose other ends are journaled on a jamb-related hinge part in the form of an elongated supporting arm. On the side of the inner link facing the outer link a cam is articulated with its free end facing the supportring arm and is urged by a spring inserted between the cam and the pivot eye of the inner link against a counter-surface formed by a section of the inner wall of the supporting arm such that its face forces the hinge resiliently into the closed position upon passing a dead point in the closing movement. The section of the wall of the supporting arm that forms the counter-surface is provided at least in the surface area cooperating with the cam with a smooth, wear-resistant and friction-reducing surface.
