发明名称 Collapsible shade structure
摘要 A collapsible shade structure includes a plurality of foldable frame members each having a folded and an unfolded orientation. A fabric material is provided for substantially covering the frame members to form a side panel for each frame member, each side panel assuming the unfolded orientation of its associated frame member. Interconnecting portions of the fabric material form a hinge portion between each frame member. 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.
