Abstract
A unique collapsible apparatus for supporting an article; the apparatus has at least a first, second, and third leg assembly, an upper end of each leg assembly pivotally secured to extend from an upper support member in a generally symmetrical fashion. A lower end of each leg assembly pivotally secured to extend from a lower support member (which may be in the shape of a collar). Each leg assembly has a unique hinge-fitting interconnecting a first and second elongated subassembly; a hinge-fitting may comprise a first and second extension pivotally enjoined. Each hinge-fitting permits a pivot range of rotation; preferably, this pivot range may be up to 90-degrees, up to 170-degrees, or just under 180-degrees. The elongated subassemblies may each be comprised of a plurality of telescoping tubular sections adapted for interlock. The telescoping tubular sections of an elongated subassembly may be sized for interchangeability with telescoping tubular sections of another elongated subassembly. Upper support member may have a plurality of fork extensions to which upper ends of the leg assemblies are pivotally secured. Upper support member may have an aperture for accepting an article, e.g…
