Abstract: The tray assembly for mounting to a wheelchair includes a tray having a top surface and bottom surface, a member for supporting the tray to an arm rest of the wheelchair, the member being mountable on the arm rest of the wheelchair, and a double hinge for pivotably affixing the tray surface to the member for supporting the tray surface. The double hinge has a first and second pivotal axis where pivotal movement of the tray from the use position to an intermediate position occurs about a first pivotal axis and pivotal movement of the tray from an intermediate position to a storage position occurs about the second pivotal axis. The tray assembly enables the tray surface to extend on the outerside on the arm rest and allows the tray to be folded into a non-use position alongside the wheelchair.
