ABSTRACT:
A cart includes a frame, a leg attached to the frame, and a wheel movable relative to the frame. A handle is operatively associated with the wheel and with the frame, whereby the work surface is in a normally stationary, inoperative position, and positive movement of the handle causes the wheels to engage the floor and place the work surface in an operative, movable mode. The work surface is engineered so that it is automatically returned to its stationary mode when no user is actively placing the work surface in its movable mode.
