ABSTRACT:
A plurality of side rails, cross rails, side and corner legs are prefabricated from a square, tubular, 12 gauge steel material. Separable side and corner connecting members formed of substantially the same tubular steel material include projecting arms and bridging members that are inserted into the open ends of the side rails, cross rails, side and corner members to assemble the table. The connections are secured by bolting the structural frame members to the connecting members. Tubular rectangular side tracks are secured to the upper surface of the side rails in certain installations to provided support for wheeled carriages that are adapted to move longitudinally of the table. The side connectors and corner connectors are, in general, fabricated identically, then utilized in the assembly by slightly different orientation, hole patterns, and the use of the different bridging members.
