ABSTRACT:
A wheelchair work tray multipivotal mounting assembly may be easily mounted and removed from a wheelchair and is adapted to receive a multipivotal mount for use by wheelchair occupants. The mounting assembly is adapted for mounting over one arm of a wheelchair and includes a pair of plates adapted for sliding over a wheelchair arm. Once positioned on the arm, the mounting assembly may be locked into place by a locking assembly including a lever operated cam. The cam secures the mounting assembly to the wheelchair arm and resists displacement or rotation in any direction. A receiver accepts a multipivotal mount supporting a tray and enables vertical adjustment and rotation of the multipivotal mount about a vertical axis. The mounting assembly may be removed by rotating the lever counterclockwise and swinging the locking assembly outward.
