ABSTRACT:
For swingably mounting a door on a jamb, a dual action self closing hinge has a stationary component which seals, shields, and carries a stationary cam and a rotatable cam follower. The cam elements cooperate with one another to displace the cam follower and attached door panel upwardly during an opening movement and permit the automatic downward movement of the cam follower and door panel upon release of the door panel from an open position. Simultaneous with the cam action, an offset hinge mechanism elevates the center of gravity of the door panel during opening, and likewise provides for the automatic return of the door panel to the closed position to improve the self-closing action of the door. In addition, a cam angular position lock enables the closed position of the door relative to the jamb to be easily adjusted.
