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.

An adjustable pintle arrangement for a door pivot assembly of the general type wherein a pintle device is carried by a door member and pintle accommodating means is mounted to the door frame, said adjustable pintle arrangement comprising, a base member mountable to the door member in a relatively fixed position, a slide member carried by said base member for longitudinal movement relative thereto, drive means mechanically inter-connecting said slide member and base member for producing controlled longitudinal movement of said slide member relative to said base member, and a pintle device carried by said slide member and projecting therefrom, such that operation of said drive mechanism will produce relative longitudinal movement of said pintle device with respect to said base member, said slide member including an aperture formed therein, said pintle device being disposed in said aperture, and spring means biasing the said pintle device outwardly of said slide member so as to project from the upper surface thereof.
