Abstract: A tray attachment for a wheelchair. In an embodiment, the tray attachment includes a mounting tube for mounting the tray to a wheelchair. Further, a slider extension tube is disposed within the mounting tube for supporting the tray. In addition, a first ball knob assembly is mechanically coupled to the slider extension tube for supporting the tray. Moreover, a second ball knob assembly is mechanically coupled to the slider extension tube for supporting the tray. In the present aspect, the slider extension tube rotates as the tray is moved from a stored position to a utilization position, such rotation places the first ball knob assembly adjacent to an edge of the tray and the second ball knob assembly beneath the tray, thereby providing lateral and vertical support to the tray on the attachment side.

Abstract: A tray assembly which provides a tray and may be attached to most chair assemblies, such as a wheelchair, stationary chair, or the like, is disclosed. The tray assembly is constructed so that the tray is movable between a utilization position and a storage position while still allowing an occupant of the chair assembly to use the chair assembly in its fullest capacity. A first arm of the tray is connected by a swivel assembly to an extension member. The extension member is coupled with a mounting tube, the extension member may rotate and slide in a telescopic fashion relative to the mounting tube and be removed from the mounting tube. The mounting tube includes a ball knob assembly and is coupled to a support arm of the chair assembly. A second arm of the tray includes a multiple connection assembly which couples with a fastener assembly to affix the tray in the utilization position and couples with the ball knob assembly to affix the tray in the storage position.
