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.

What is claimed is: 1. A portable collapsible stand comprising: (a) a first support frame capable of supporting a first generally planar surface, said first frame having an upper portion, a middle portion and a lower portion, (b) a second support frame capable of supporting a second generally planar surface, said second frame connected to said lower portion of said first frame, said second frame projecting generally perpendicularly from said first frame; (c) a third support frame capable of supporting a third generally planar surface, said third frame having a first end and a second end, said third frame first end rotatably connected to said first frame upper portion whereby said third frame is pivotable from a first position generally parallel to said first frame to a second position generally perpendicular to said first frame; (d) a work surface frame capable of supporting a partially planar surface, said work surface frame rotatably connected to said first frame upper portion; (e) at least one telescoping strut, said telescoping strut pivotably connected to said first frame and said work surface frame; (f) at least one primary wheel rotatably connected to said first frame lower portion; and (g) at least one secondary wheel rotatably connected to said first frame upper portion; whereby said stand is capable of assuming a collapsed position in which said first frame, said third frame and said work surface frame are generally parallel, and an operating position in which said third frame is generally perpendicular to said first frame and said work surface frame is generally parallel to a surface supporting said stand and whereby said stand is movable across said surface supporting said stand on said primary and secondary wheels when said stand is in said collapsed position and said first, third and work surface frames are generally parallel to said surface supporting said stand. 2. The stand of claim 1, wherein said first frame and said second frame are integrally connected. 3. The stand of claim 1, wherein said telescoping strut is capable of at least partially urging said work surface frame between said collapsed position and said operating position. 4. The stand of claim 1, wherein said work surface frame supports a tool such that said tool weight is substantially directed toward an end of said work surface frame that is opposite of said rotatable connection of said work surface frame to said first frame upper portion. 5. The stand of claim 1, wherein said telescoping strut comprises a fluid cylinder. 6. The stand of claim 1, wherein a tool attachment is integrated with said work surface frame. 7. A portable collapsible stand comprising: (a) a first support frame, wherein said first frame has an upper portion, a middle portion and a lower portion, said first frame comprising a generally L-shaped left side member and a generally L-shaped right side member, said left side member and said right side member connected by a plurality of cross members; (b) a second support frame, wherein said second frame has a first end and a second end, said second frame first end rotatably connected to said first frame upper portion whereby said second frame is pivotable from a first position generally parallel to adjacent said first frame to a second position generally perpendicular to adjacent said first frame; (c) a third support frame capable of forming at least a partially planar surface, wherein said third frame is rotatably connected to said first frame upper portion; (d) at least one telescoping strut, said telescoping strut pivotably connected to said first frame and said third frame; (e) at least one primary wheel rotatably connected to at least one of said first frame lower portion and said first frame middle portion; and (f) at least one secondary wheel rotatably connected to said first frame upper portion; whereby said stand is movable across said supporting surface on said primary and secondary wheels when said stand is in a collapsed position and said upper and middle portion of said first frame, said second frame, and said third frame are generally parallel to said supporting surface. 8. The stand of claim 7, wherein said stand is capable of assuming said collapsed position with said upper and middle portion of said first frame, said second frame, and said third frame generally parallel, and an operating position in which said second frame is generally perpendicular to said upper and middle portions of said first frame and said third frame is generally parallel to a surface supporting said stand. 9. The stand of claim 7, wherein said telescoping strut is capable of at least partially urging said third frame between said collapsed position and an operating position. 10. The stand of claim 7, wherein said third frame supports a tool such that said tool weight is substantially directed toward an end opposite of said rotatable connection of said third frame to said first frame upper portion. 11. The stand of claim 7, wherein said telescoping strut comprises a fluid cylinder.
