Abstract
A collapsible structure includes a plurality of foldable frame members each having a folded and an unfolded orientation. A fabric material is provided for covering portions of the frame members to form a side panel for each frame member. The structure can have a removable roof. The structure may be folded and stored by folding the side panels and their corresponding frame members on top of each other about the hinge portions to have the side panels and frame members overlying each other. The overlaying side panels and frame members are then collapsed by twisting and folding to form a plurality of concentric frame members and side panels to substantially reduce the size of the shade structure.
