ABSTRACT:
A folding frame system includes a roof assembly including at least three pivotably attached strut pairs, adjacent pairs of the at least three pivotably attached strut pairs defining at least three corners of the roof assembly. The roof assembly is movable between a roof assembly closed position in which struts of the at least three strut pairs are disposed parallel to each other and a roof assembly open position in which struts of the at least three strut pairs are locked in non-parallel positions and ends of the struts of each strut pair of the at least three strut pairs define a rectangle. The folding frame system also includes a folding leg assembly disposed at each of the at least three corners of the roof assembly. Each folding leg assembly includes a leg strut assembly. The leg strut assembly includes a top leg strut and a tubular bottom leg strut in which the top leg strut is telescopingly slidable between a top leg strut closed position and a top leg strut open position. A top end of the top leg strut includes a joint pivotably attaching the top end of the top leg strut to an end of a strut of a strut pair of the at least three strut pairs. The folding leg assembly also includes a lock for locking the top leg strut in the top leg strut open position. The folding leg assembly also includes at least one arm strut assembly. The arm strut assembly is pivotably attached at a bottom end to a point on the bottom leg strut. A top end of the arm strut assembly includes a joint pivotably attaching the top end of the arm strut assembly to at least one strut of the strut pair to which the top end of the top leg strut is pivotably attached.
