ABSTRACT:
A pair of planar members which form the surface of a table are arranged in co-planar relationship on flanges extending inwardly from the opposite side rails of a rigid, non-expandable frame. The two planar members are slidable between a first, closed position in which the adjacent edges of the two planar members abut each other and a second, open position with the planar members spaced apart. In the open position, a third auxiliary planar member, having a width equal to the first two and normally kept separate from the table, is inserted between the spaced adjacent ends of the planar members and supported on the flanges. The frame is formed of a pair of spaced side rails, end rails connecting the side rails, and four legs extending downwardly from the corners of the frame member.
A locking mechanism interconnects the side rails and the two planar members, so that the two planar members are held together in locked relationship in either the first position or the second position.
