Abstract
A frame for a shelter including at least four legs and at least four arch rails, wherein the legs and/or arch rails are preferably coupled together with rib members scissor-type coupled together and wherein the shelter is expandable and collapsible upon the arch rails being rotated relative to the legs such that angles greater than 90° and less than 90° can be formed (i) between the first leg and first arch rail, (ii) between the second leg and second arch rail, (iii) between the third leg and third arch rail, and (iv) between the fourth leg and fourth arch rail, and wherein angles less than 180° and greater than 180° can be formed (i) between the first arch rail and the third arch rail and (ii) between the second arch rail and the fourth arch rail.
