ABSTRACT:
A pressure operated hinge for swingably mounting a door on a frame behind their exposed front portions is of three parts involving a box having pressure elements to be mounted within a back-positioned cavity in the door, a swing arm part that carries a rounded, pin-like guide surface provided with at least one contoured slot therein, and a frame mounting plate part that is adapted to be adjustably secured by a set screw and a tongue and groove connection to the swing arm part. The operating relation between the pressure elements and the guide surface is designed to minimize friction therebetween, and the swing arm is adapted to move into the box to provide a substantially flush positioning when the door is fully closed.
