Abstract
Over-center hinge for a cabinet door, having a supporting-wall-related part which can be fastened to the supporting wall of a cabinet, and a door-related part joined pivotingly to the supporting-wall-related part by a linkage mechanism and constructed as a plug-in cup. In the peripheral wall of the cup a tongue biased toward the interior of the cup by a compression spring is mounted for pivoting over a given angle. On its contour surface projecting slantingly into the interior of the cup a contact surface provided in the area of the linkage end of the supporting-wall-related part, slides during a portion of the opening and closing movement between the hinge closed position and dead center position and urges the door into the closed position. An abutment or catching surface is provided on a detent element which, in the dead-center position, engages the tongue on the one hand and the plug-in cup on the other hand and holds the tongue in the dead-center position, and which is so constructed and arranged that, in the portion of the hinge movement between the dead-center position and the closed position, it is forced out of the tongue holding position to a tongue releasing position.
