A knockdown portable shelter includes two spaced supports each formed of elongated members that can be separated from each other at couplings securing the elongated members to each other. The elongate members include leg portions and a roof portion. A sheet like covering material extends between the roof portion of the spaced supports and at least parts of the leg portions. The covering material is substantially more pliable along the direction extending between the two spaced supports than along a perpendicular direction. Hinges allow folding of the material along lines extending between corresponding couplings. Disconnection of elongate members at the couplings allows the covering material to be folded along the hinges and rolled up along the direction extending between the supports. One example of a suitable covering material is single face corrugated hollow core material. The elongate members are preferably hollow plastic tubes and the couplings are hollow plastic elbows made of PVC.

[ I claim:] [1.] Knock down portable shelter comprising two spaced supports, each support being formed of a plurality of elongate members; coupling means for releasably connecting corresponding adjacent ones of said elongate members in each of said supports, said supports defining spaced generally downwardly extending leg portions and roof portions extending between said leg portions to form a shelter space below said roof portions said supports being arranged exteriorly of said shelter space and in generally parallel planes spaced from each other along a predetermined direction; and a substantially rectangular sheet of covering material having opposing longitudinal edges and extending between said roof portions and at least parts of said leg portions, said sheet of covering material being pliable along said predetermined direction and more rigid along a direction generally orthogonal to said predetermined direction, the pliability of said sheet of covering material along said predetermined direction being such that said sheet can be substantially continuously bent along lines normal to said predetermined direction the entire distance between said spaced supports whereby said sheet of covering material can be readily rolled into a helical or spiral roll with an axis normal to said predetermined direction; fastener means for attaching each one of said opposing longitudinal edges of said rectangular sheet of covering material to an associated one of said spaced supports; hinge means on said sheet of covering material extending between associated coupling means rendering said covering material foldable between said coupling means in a direction normal to said predetermined direction and forming folded surfaces in said sheet of covering material for stiffening the same to minimize drooping of said sheet of covering material along said predetermined direction in the assembled shelter, disconnecting of connected elongate members of each support at said coupling means allowing collapse of said elongate members of each support from an assembled state by folding said sheet of covering material about said hinge means and said leg portions into said shelter space, within said parallel planes, relative to associated roof portions to position said leg portions and said roof portions in proximity to each other on opposite sides of said covering material while said panel portions are substantially co-planar and subsequently rolling of one support relative to another support along said predetermined direction to roll said covering means into a roll containing said elongate members and having an axis essentially parallel to said orthogonal direction.
