Interior modular panel assemblies

Claim 1

An interior modular panel assembly comprising, in combination: a plurality of identical rectangular panels, each panel having edge railings on its opposite side, top, and bottom peripheral edges, each of said edge railings defining a cylindrical recess opening out in a front slot parallel to the axis of the recess and edge of the panel to which the railing is affixed and a rectangular recess behind its cylindrical recess when viewed in cross-section; a hinge structure in the form of a hollow square column extrusion, the corners thereof including extending integrally formed hollow cylindrical inserts opening out in slots and each being dimensioned to be received in a snapin fashion in any one cylindrical recess in a railing by circumferentially contracting and then expanding so that from two to four panels may be hinged to a single hinge structure and disposed at desired angles to each other by pivoting movement of any one of the inserts in its corresponding recess about an axis coinciding with the axis of the recess; and corner pieces of identical construction having projections at right angles to each other of rectangular cross-section for reception in the rectangular recesses at the ends of side and top railings to finish off the upper corners of the panels and cover the upper ends of the cylindrical inserts of the hinge structure when received in the cylindrical recesses of the railings.
