GRAVITY ACTUATED HINGED DOOR MOUNTING

摘要

This invention relates to apparatus for pivotally mounting a door, window or like closure in a frame, comprising at least a top and a bottom hinge construction, each having the appearance of a conventional hinge, but at least the top and the bottom constructions having substantially different pivotal means permitting adaption thereof for a number of relatively different functions. Each said pivotal means includes means defining at least a pin and a complementary recess adapted to locate relative to each other in such a manner as to permit relative departure of the recess from a position coaxial with said pin and relative rotation about a predetermined axis.
