ABSTRACT:
An adjusting device embodying the concepts of the present invention is incorporated in a mount by which a tray assembly adapted to support an input device for a computer is supported from a chair. The proximal end portion of a mounting bar is supported from a chair such that the mounting bar is disposed substantially horizontally from the chair. A substantially vertically disposed support assembly is rotatable mounted from the distal end portion of the mounting bar. The first end portion of an arm assembly is supported for articulation from the pivot assembly about an articulating axis that is disposed substantially horizontally. A tray assembly is pivotally supported from the second end portion of the arm assembly about an pivotal axis that is disposed substantially horizontally. Means may be provided selectively to establish the distance between the mounting bar and the articulating axis. Locking means may also be provided selectively to secure the pivotal position of the tray assembly with respect to the arm assembly, the articulated position of the arm assembly with respect to the support assembly and to establish the distance between the mounting bar and the articulating axis.
