  • Patent number: 9089208
    Abstract: A tray attachment is provided for use with household items. A first embodiment and a second embodiment allow the tray attachment to be used with horizontal features (e.g. tables) and vertical features (e.g. arm rests). For use with horizontal features, the first embodiment uses a pair of clamps and handles connected below a planar surface. The clamps can be pressed against the bottom of a table, held in place thanks to the interaction between a locking mechanism and retention mechanism. A planar body serves is connected atop the carriage and serves as a tray, including an indent for holding items such as plates or cups. In the second embodiment a moveable clamp jaw is clamped against a stationary clamp jaw by means of a carriage which slides along an elongated track. The planar body again serves as a tray, effectively extending the usable area of a table or similar feature.
