Abstract:
1. A hinge assembly for a self-closing, bidirectionally swinging door which is swingable between an open position and a normally closed position, said hinge assembly comprising: a frame-mountable first bracket assembly comprising a frame bracket mountable on a door frame proximate an upper portion of said door, and a hinge pin projecting vertically downwardly from said frame bracket, said hinge pin defining a vertically extending pivot axis for said door and having a bottom end and a support head which defines an upward-facing, annular support ledge for rotatably supporting said door, said support ledge including support notches on opposite sides of said hinge pin; a door-mountable second bracket assembly which is mountable to said door for suspending the door from said first bracket assembly for swinging rotation about said pivot axis, said second bracket assembly including rollers which are rotatable about a horizontally extending roller axis and are vertically supported on said support ledge of said hinge pin, said support notches receiving said rollers therein to rotationally bias said second bracket assembly to a first position corresponding to the closed position of said door, said second bracket assembly being displaceable vertically relative to said hinge pin wherein vertical displacement of said bracket assembly permits said rollers to move vertically out of said support notches during rotation of said second bracket assembly to a second position corresponding to the open position of said door supported by said second bracket assembly; said second bracket assembly comprising first and second side brackets which each include a respective one of said rollers thereon, upper ends of said first and second side brackets each including a notch which align in opposing relation with each other to define a bore through which said hinge pin extends, said first and second side brackets being formed separate and positioned separately next to said hinge pin with said notches capturing said hinge pin therebetween with said rollers being positioned vertically on said support ledge, said first and second side brackets being secured together so that said second bracket assembly is rotatably and vertically supported in engagement with said first bracket assembly; said second bracket assembly includes a door bracket which is mountable to said door separate from said first and second side brackets; said first and second side brackets include a support plate which is releasably engageable with said door bracket; and said door bracket is displaceable onto flanges of said support plate to a support position for suspending said door on said first and second side brackets.
