Abstract
A folding frame assembly includes a folding frame including a plurality of pairs of struts connected end-to-end by a plurality of hub assemblies. Struts of each strut pair are pivotably connected at ends thereof to first and second ends of a hub assembly and are foldable relative to each other between a closed position in which the struts are substantially parallel to each other, the first ends of the hub assemblies are all substantially adjacent, and the second ends of the hub assemblies are all substantially adjacent, and an open position in which the struts define non-zero angles with each other, ends of the struts of each strut pair are separated from each other by the hub assemblies, and first and second ends of the hub assemblies are non-adjacent. The folding frame assembly also comprises a leg comprising two elongated members, a portion of each elongated member being fixed to the first end of the hub assembly and each elongated member being slidably mounted relative to the second end of the hub assembly.
