Abstract
A multiple-paneled folding tabletop is supported by two attached foldable subframes which interlock when unfolded and form a single frame supporting the tabletop by its perimeter. The tabletop consists of a series of rectangular panels attached to each other along their long edges by hinges. The direction of folding of the hinges alternates between panels. A subframe is affixed to each of the two end panels. The subframes include two swiveling bars which can move in a plane parallel to the unfolded tabletop. Each bar, when folded, is contained within a subframe and, when unfolded, spans the center panels and interlocks rigidly with the opposite subframe. Two foldable legs are attached to each subframe which, when folded, are contained within the subframes.
