Claim:
A collapsible support structure comprising a plurality substantially triangular frame sections each having corners connected by flexible joints, each frame section including a first elongated rigid tubular member having opposed first and second ends and adjacent each end of the first member a pair of openings, a second elongated rigid tubular member having opposed first and second ends and adjacent each end of the second member a pair of openings, and a collapsible elongated tubular member having opposed first and second open ends, said collapsible tubular member having a rigid state and a collapsed state so the support structure is foldable when said collapsible member is collapsed, a first predetermined number of the frame sections forming a frame roof of the support structure and a second predetermined number of the frame sections forming a frame sidewall of the support structure, said sidewall having a top segment including the collapsible tubular member of each frame section forming the frame roof and a bottom segment including the collapsible tubular member of alternate frame sections forming the frame sidewall, the first ends of said first and second tubular members of the frame sections forming the frame roof being open and tied to form an apex by a flexible line passing through the pair openings and open end in each of said first ends of said first and second tubular members of the frame sections forming the frame roof to provide a flexible joint at the apex, enabling the frame roof to fold inward without untying the flexible line when said collapsible tubular members of the frame sections forming the frame roof are collapsed.
