ABSTRACT:
A load supporting and elevating stand capable of quick assembly, without fasteners or gluing, is made up of a series of flat panels. The preferably wooden panels are rectangular and relatively thin, and can be stored and shipped flat and compactly. Slots in the two leg-member panels enable them to be interlocked to form a supporting base. Grooves in these two panels slidably receive four vertical brace panels, rigidifying and locking the base in the desired configuration. A top panel rests horizontally on the base, with grooves in the underside of the top panel receiving the top edges of the interlocked leg-member panels, increasing stability and locking the top panel in place.
