Abstract
Each of two identical hinge plates has projecting from one longitudinal side edge thereof four, spaced, coaxially aligned barrels, two of which have therethrough coaxial bores, and each of the other two of which has a reduced-diameter cylindrical pin projecting from one end thereof. The four barrels of each plate are arranged so that the two barrels containing bores are consecutive or adjacent to each other, and the two barrels bearing the cylindrical pins are adjacent to each other. A hinge is assembled by inserting the pins of each hinge plate coaxially and rotatably into the barrel bores in the other plate. Thereafter a locking element may be inserted between a pair of adjacent barrels to prevent accidental disengagement of the cylindrical pins from the barrel bores.
