Title: Retractable wheelchair tray mechanism

Abstract: A convenient tray is provided for a wheelchair wherein the tray retracts onto a housed roll mounted beneath one armrest of a conventional wheelchair and extends across the lap of the wheelchair victim to be engaged by a releasable catch mechanism beneath the opposite armrest. The sheet material of which the tray is made has a transverse upwardly convex arch over its length to provide it with rigidity when it is extended in the manner conventionally subscribed to by tape measures, this sheet becoming flexible in the longitudinal direction for rolling when the sheet is retracted onto its roller.
