Collapsible structures
A collapsible play structure comprises one or more play modules connected together, each play module comprising at least three foldable frame members, each having a folded and an unfolded orientation. A fabric material substantially covers each frame member to form a side panel for each frame member when the frame member is in the unfolded orientation. Each side panel further comprises at least three sides. The left side of each side panel is connected and hinged to the right side of an adjacent side panel, and the right side of each side panel is connected and hinged to the left side of another adjacent side panel. The bottom side of each side panel is adapted to rest on a supporting surface to support the play module.
1. A collapsible structure, comprising:
a first panel having a first foldable frame member having a folded and an unfolded orientation, and a first fabric material covering portions of the first frame member to form the first panel when the first frame member is in the unfolded orientation, the first panel having a first side;
a second panel having a second foldable frame member having a folded and an unfolded orientation, and a second fabric material covering portions of the second frame member to form the second panel when the second frame member is in the unfolded orientation, the second panel having a first side;
a first material stitched to the first sides of the first and second panels, and connecting the first and second panels in a manner in which the first panel and the second panel are generally parallel to each other;
wherein each of the frame members is twisted and folded to form a plurality of concentric rings in the folded orientation; and
wherein each of the first and second panels has a second side opposite the first sides, and further including a second material stitched to the second sides of the first and second panels.
