ABSTRACT:
A convertible, foldable stand and portable tray combination is designed to yield a maximum of utility. The stand is built of identical frames assembled in link relationship, the legs having slip-grip feet which are restrained in lateral spread by flexible reins. The stand features a removable footrest and removable braces. Portable trays, having invertible surfaces, handles, rails, and locks, feature open corners which act to facilitate many conversion arrangements on and off the stand. Tray conversions are described for obtaining vertical suspension, surface compartments, game boards, a collapsible tray system, aperture boards, side to side and edge to edge connections, bedroom lapboard, and, on the stand, many table combinations of level, slope, and level plus slope. One or more trays store between upper frame sections of the folded-up stand.
