  • Patent number: 3954068
    Abstract: A table-tray combination having a foldable supporting structure consisting of a pair of legs, held in a vertical position by bases pivoted from the lower ends of each leg and locked in place by slotted braces and detent studs. An arm frame, pivoted from the upper middle region of each leg, forms, together with the upper ends of the legs, the plane to which the detachable tray is clipped. When the bases and arm frame are folded for storage, the structure and tray assume an essentially flat shape. Clips, rigidly attached to each leg, hold the folded structure for storage and preclude opening them improperly.
