Abstract
A self-closing mechanism for a fully concealed hinge, which has a hinge cup for mounting on a door, and a frame wing pivotally supported thereon for attachment to a frame on which the door is mounted. The mechanism includes a combination compression coil spring retainer and plunger which is mounted on the frame wing, and positioned to be pressed against cam surfaces provided on the hinge cup. The cam surfaces are formed such that force applied to the cam surfaces by the plunger will act to maintain the door in open and closed positions, will apply a force to close the door when approaching the closed position, and otherwise will not exert either an opening or a closing force on the door.
