Abstract
Abstract A table having three major components, top, shelf and base, all constructed of light-weight wood or other light-weight materials and constructed so that the table is easily and quickly assembled and disassembled without the need for tools. All three parts simply fit together and have a handle or a hand-hole for carrying. Such a table provides art and drafting students an economical and light-weight drafting table which can be easily carried and set up. In accordance with an exemplary embodiment of the invention, the folding portable drafting table includes a folding, three panel base, a shelf adapted to be received between the panels of the base, and a removable top adapted to be placed over the base and having depending rails which form grooves therebetween adapted to receive the upper ends of the side panels of the base. The table is easily disassembled by lifting the top off the base, pulling the shelf out, and folding the side panels against the center panel of the base. The shelf and top include carrying handles, and the base includes a hand-hole for facilitating transport of the table in its disassembled form. The table is easily assembled by unfolding the base, inserting the shelf between the side panels of the base, and placing the top over the base.
