Safety hinge

A three piece, separable, safety hinge comprising in combination:

• a pair of hinge leaves each consisting of a parallel-faced flat area of approximately equal thickness but different lengths, said pair consisting of a larger length leaf formed with a central cut-out area and a smaller length leaf loosely receivable nested coplanar within said cut-out area, each leaf having means for respective attachment to an adjacent support structure such as a door and door jamb so as thereby to hinge them together,
• each leaf having a bearing tube formed along a common edge, the bearing tube of both leaves being functionally disposable in joint longitudinal alignment, the bearing tube of said smaller leaf being formed with a pair of tangentially projecting abutment lugs adapted to locate an edge of one of said support structures disposed thereagainst for attaching said smaller leaf thereto, and a flat portion of said smaller leaf extending within said cut-out area lengthwise beyond its adjacent bearing tube in both directions so as to longitudinally overlie the bearing tube of the larger leaf and thus prevent separation of the two leaves when the letter are disposed nested coplanar with each other, and
• a hinge pin characterized by a generally cylindrical shaft with a peripherally enlarged head and a distally converging, frustro-conic neck immediately beneath, which neck is frictionally engagable by insertion within said bearing tubes, whereby said pin may be removably inserted through the aligned bearing tubes and transiently engage its frustro-conic neck therewith from either end when so inserted.
