ABSTRACT:
Folding furniture to be used as a table, pedestal, supporting structure or the like which may be easily collapsed into a low-volume configuration for portability and storage. The furniture generally consists of four panels which function as top, bottom and sides, hinged together to form a rectangular structure. Adjoining panels at two diagonally opposed corners of the rectangular structure contain axially aligned bores in a tongue-and-groove assembly, receiving pins to secure the adjoining panels; this assembly allows the adjoining panels to swing obtusely. Panels meeting at the other two diagonally opposed corners of the rectangular structure are attached with hinges, allowing the panels to swing acutely. The side panels contain variously shaped support members which are hinged to said side panels. The support members are pivotal toward the interior of the table structure to rest against an adjacent panel to prevent the side panels from folding from their upright position, thus stabilizing the overall structure in its erect state.
