  • Portable work station
    Patent number: 5161766
    Abstract: A portable work station provides support for an article to be used by a person occupying available funiture. The work station has a base adapted to fit beneath the person. Preferably, the base has an axis of rotation and extends laterally therefrom. The base can rotate from an upwardly facing position on one side of the axis to an inverted position on the opposite side. An adjustable arm has a common axis of rotation with the base and extends laterally therefrom to a remote end. The base and the adjustable arm can rotate independently of each other or can be interlocked in a fixed relationship relative to each other so that the base and the arm extend in perpendicular planes. An article supporting portion is connected to the remote end of the adjustable arm. The article supporting portion can be positioned for holding the article and the portable work station can be positioned for either right or left handed applications.
