ABSTRACT:
A removable and pivotal tray which has a tray (22) for holding items on a top surface. A channel (46) with a pair of thumb screws (48) hold the tray to the arm of a portable folding chair and a hinge (54) is attached to the tray and channel. The hinge permits the tray to pivot 270 degrees from horizontal during use and then be lowered downward to the side of the chair when not in use. The tray swivels a full 360 degrees when horizontal to provide the most convenient location for the user. The pivoting is provided by the use of flanged bushing (68) disposed within a counterbore (70) in the channel, and a pair of resilient washers (72), provide controlled resistance to maintain the trays position. The tray may be flat or include upstanding flanges (32) and alternatively a lid (34) or spring clip (28). A kickstand (82) may be optionally utilized to tilt the tray angularly for reading or writing. A second embodiment omits the channel and thumb screws and incorporates a flange bushing directly into a chair arm (80) for a non-removable integral tray.
