Abstract:
1. A locking door hinge, comprising: a) a first leaf having a thickness, an inner edge, an outer edge, upper and lower edges, first and second planar surfaces, and a plurality of pin receptive sleeves extending along the inner edge, each sleeve having a sleeve bore; b) a second leaf having a thickness, an inner edge, an outer edge, upper and lower edges, first and second planar surfaces, and a plurality of pin receptive sleeves extending along the inner edge, each sleeve having a sleeve bore; c) the sleeves of the first and second leaves being offset, enabling the sleeve bores to be aligned along a common axis that defines a hinge pivot; d) a pivot pin that extends through the sleeve bores, enabling the leaves to move between open and closed positions, the outer edges of the leaves being next to each other in the closed position; e) a pair of locking flanges placed on the edges of the first leaf at a position that is spaced away from the sleeves; f) each flange having a locking pin receptive flange opening; g) the flange opening being spaced a distance from the first leaf that is greater than the thickness of the second leaf; h) a locking pin that is removably connectable to the flanges at the flange openings in a locking position; and i) wherein in the locking position, the leafs are in the closed position and the locking pin constrains movement of the second leaf relative to the first leaf by contacting a planar surface of the second leaf at a position that is spaced in between the leaf inner and outer edges.
