  • Patent number: 4946058
    Abstract: Tray apparatus for patients, including a tray member having a bottom and contiguous sides upstanding from periphery thereof, and a removable plate, releasably disposed over said tray member and provided with a series of receptacle-receiving apertures. The apertures accommodate the placement of plate, cups and the like which, when inserted into the apertures, contact and are supported by the bottom of the tray member. Upstanding arms are fixably disposed relative to opposite sides of the tray member and are articulatively coupled to horizontal cross-bar structure by means of a type of link. The composite tray structure enjoys a gravity-assist, whereby such tray structure is maintained essentially in a horizontal position even though its support might be jarred or even moving. Locking means is provided for releasably locking the tray structure to external support structure.
