Abstract
The door member of a self-closing hinge includes a cup which is concealed within a pocket formed in the inner side of a door. A curl on the frame member of the hinge pivotally receives a hinge pin which is carried by the cup. To effect the self-closing action, a leaf spring is mounted on the outer side of the end wall of the cup and includes a tongue which extends through an opening in the end wall and into resilient bearing engagement with the curl.
