ABSTRACT:
A portable collapsible stand includes first, second, and third support frames, a work surface frame, and a telescoping strut pivotably connected to the first and work surface frames. The second frame projects perpendicularly from a lower portion of the first frame. A first end of the third frame is rotatably connected to an upper portion of the first frame such that the third frame pivots from a first parallel position to a second perpendicular position with respect to the first frame. An upper portion of the work surface frame is rotatably connected to the upper portion of the first frame. In operation, the stand can assume a collapsed position in which the first, third and work surface frames are generally parallel, and an operating position in which the third frame and first frame are perpendicular and the work surface frame and surface supporting the stand are parallel.
