ABSTRACT:
A concealed self-closing hinge for mounting a door for swinging on a fixed frame. The door member of the hinge includes a cup which is concealed within a pocket formed in the inner side of the door. A durable plastic cam on the arm of the frame member of the hinge receives a hinge pin which is disposed in slots in the cup. A leaf spring is supported by the base of the cup and is bowed around a bridge to bear against and ride on the cam to effect the self-closing action and also to hold the hinge pin assembled in the slots in the cup.
