发明名称 Collapsible tripod stool
摘要 A collapsible tripod stool for bodily and tangible item support is described. The triangularly shaped seat is supported by a plurality of tubular legs, which may be fused, glued, or otherwise connected to the corners of the seat. In one embodiment, telescoping legs are comprised of upper, central, and lower sections, the central leg section having two different diameters to prevent section contact, and being cast as one piece to eliminate welded surfaces. The central leg sections are attached to a triangularly-shaped central pivot joint by threaded members to prevent mobilization of the legs with respect to one another. The telescoping legs are angled to maximize ground surface contact and further stabilize the tripod stool of the present invention. In another embodiment, tubular legs are comprised of upper and lower sections which connect to one another and are coupled together by an elastic cord within each leg. The leg sections are conveniently detached at their approximate midpoints and folded together in a compact bundle. A pivot joint comprises fabric straps secured to each leg and centrally joined to one another.
