A plurality of U shaped support bars are pivotally connected to the base frame and are of such a size that they can nest inside the bottom side of the base frame. Each of the U shaped support bars incorporates a plurality of wheels or casters. The terminal ends of the U shaped support bars are pivotally connected to the base frame. Each of the U shaped support bars is associated with a latch means whereby, the U shaped support bars can be locked into a plurality of positions.
