ABSTRACT:
A door positioned adjacent a door frame or jamb has a hinge which comprises an elongated profile bracket mounted on the frame and extending over at least a part of the door height. Said bracket includes a leg with an extension on said leg having a first arcuate outer surface on one side and spaced therefrom a second arcuate inner surface of reduced radius. The door has along one edge a transversely arcuate bearing surface which cooperatively receives said first arcuate surface. A support mechanism on the door is spaced from said bearing surface and retainingly engages said second arcuate surface whereby the arcuate bearing surface of the door moves over said first arcuate surface and said support mechanism rotates over said second arcuate surface. The mounting of said profile bracket on said door frame or jamb includes a second extension on said leg opposite from and a mirror image of said first extension including corresponding first and second arcuate surfaces. The door frame or jamb along one edge has a transversely arcuate bearing surface and a support mechanism which is a mirror image of the door bearing surface and support mechanism whereby after the door has rotated substantially 90.degree. with respect to the profile bracket, said door and profile bracket are adapted to rotate an additional 90.degree. relative to said door frame.
