Abstract
First and second hinge leaves are mounted respectively on the body and the door with one hinge leaf having a pivot pin and the other hinge having a hinge aperture adapted to engage the pivot pin to establish a door hinge pivot axis. The first and second leaves have flanges which interengage one another through the normal range of pivoting movement of the door between open and closed position so as to maintain the engagement between the hinge aperture and the pivot pin. The door is separable from the body by pivoting the door beyond the range of normal pivoting movement to disengage the bearing portions of the hinge leaves from one another and then lifting the door axially of the hinge pin axis to disengage the hinge aperture and the pivot pin. The separable door hinge also includes an offset auxiliary pivot axis provided by an alignment abutment on one of the hinge leaves axis and an alignment notch provided on the other of the hinge leaves. The alignment abutment and the alignment notch come into engagement with one another during attempted rehanging of the door and enable swinging movement of the door to carry the pivot pin and the pivot aperture in axial alignment with one another so that the door mounted hinge leaf may be lowered onto the body mounted hinge leaf.
