ABSTRACT OF THE DISCLOSURE The specification describes an accordion folding door or other closure comprising a plurality of vertical panels of extruded material each having a longitudinally continuous male hinge element along one vertical edge thereof and a longitudinally continuous female hinge element along the other vertical edge thereof with each panel being of unitary, one-piece construction. The hinge elements and panels are arranged so that during movement of the door from the extended to retracted position, adjacent panels fold in a zig-zag manner relative to each other. The hinge elements are so constructed that inter- connection and separation of the panels is attained by longitudinal sliding movement of the male and female hinge elements in relation to each other. A locking means is provided in the form of a projecting means associated with the female hinge element which engages with recess means associated with the male hinge element to block relative longitudinal movement between interengaged panels while permitting relative pivotal movement between interengaged panels. The locking means includes a structure connected with, mounted on or otherwise associated with the female hinge element so that it is stationary in relation thereto and includes a projection which extends into a recess, groove, slot, or similar structure in the male hinge element. The female hinge element is of generally channel-shaped configuration and is constructed of plastic material having sufficient resiliency and flexibility to enable deflection thereof sufficient to enable assembly and disassembly of adjacent panels by longitudinal sliding movement relative to each other after the locking means is assembled with the channel-shaped female hinge element.
