ABSTRACT:
Detachably mounted patient serving trays. A pair of laterally extensible handle members are slidably mounted at opposite ends of a base member that provides a support surface for food or other items disposed thereatop. Clamping members specifically designed to releasably engage tubular structures are fixedly secured and depend to each handle member so that preselected tubular portions of a bed, chair, wheelchair, or other bodily support structure may be releasably engaged by such clamping members. The handle members are positionable in an infinite plurality of functional positions of adjustment so that the tray may be used in conjunction with bodily support structures of differing sizes and shapes. The design also permits storage of the tray on the frame of any bodily support structure of tubular construction.
