Abstract
The present invention relates generally to improvements in pivot assemblies for vertically hung doors and more particularly to novel practical pivot assemblies for use with door members of the type in which the pivoted vertical edge thereof is in substantial abutting relation with a complementary vertical door frame member when said door member is in closed position. The pivot assembly disclosed herein includes door fittings for attachment to the upper and lower corner portion of a door member and door frame fittings for association with the upper and lower horizontal sections of an associated door frame. Each door fitting carries a pintle fixed at one extremity to the door fitting and at the opposite extremity to a member or plate having a polygonally shaped periphery. The polygonally shaped member is nested within a recess in the door frame fitting defined by an internal periphery adapted to cooperate with said polygonally shaped member so as to effect horizontal displacement of the door member as said member is shifted from its closed position.
