Abstract
An adjusting assembly for mounting a supporting tray assembly to a chair using one or more arm assemblies. The proximal end portion of a mounting bar is secured to a chair such that the mounting bar is disposed substantially horizontally. A substantially vertically disposed support assembly is mounted from the distal end portion of the mounting bar, and the support assembly may be rotatable about a vertical axis, if desired, to facilitate entering and exiting the chair. If only one arm assembly is used, the first end portion of an arm assembly is supported for articulation from the pivot assembly, and a tray assembly is pivotally supported from the second end portion of the arm assembly. If two or more arm assemblies are utilized, each arm assembly has a housing with first and second end portions. One end portion of one arm assembly is supported from a chair for articulation about a first articulating axis, and a tray assembly is pivotally supported from one end portion of another arm assembly for movement about a pivotal axis. The other end portions of the arm assemblies are interconnected for relative articulation about one or more intermediate axes. Locking means operatively interact with the arm assemblies to secure: (1) the selected position of the articulating arm assemblies about the first articulating axis, (2) the selected pivotal position of the tray assembly about its pivotal axis; and, (3) the selected articulation of the arm assemblies with respect to each other about the intermediate articulating axes.
