ABSTRACT:
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.
