Abstract

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. Alternatively, frame retaining sleeve portions may be used to interconnect and retain two or more frame members from two or more adjacent side panels and to act as hinge portions. 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.

Claims

1. -15. (canceled)

16. An object, comprising:

a first panel and a second panel, each panel having a frame member that has a folded and an unfolded orientation, and a material covering its corresponding frame member when the corresponding frame member is in the unfolded orientation, wherein each frame member is collapsible to the folded orientation by twisting and folding to form a plurality of concentric rings to substantially reduce the size of the folded frame member in the folded orientation; and

a rod structure coupled to the first and second panels to maintain the first and second panels in a spaced-apart relationship between each other.

17. The object of claim 16, further including a fabric material extending between the first and second panels, with at least a part of the rod structure positioned above the fabric material.

18. The object of claim 16, further including a fabric roof extending between the first and second panels, with at least a part of the rod structure positioned above the fabric roof.

19. The object of claim 16, wherein the first panel further includes a frame retaining sleeve for retaining the frame member of the first panel, with the frame retaining sleeve attached to the material of the first panel.

20. The object of claim 16, wherein the first and second panels are parallel to each other.

21. An object, comprising:

a first panel and a second panel, each panel having a continuous frame member that has a folded and an unfolded orientation, and a material covering its corresponding frame member when the corresponding frame member is in the unfolded orientation, wherein each frame member is collapsible to the folded orientation by twisting and folding to form a plurality of concentric rings to substantially reduce the size of the folded frame member in the folded orientation; and

a rod coupled to the first and second panels to maintain the first and second panels in a spaced-apart relationship between each other.

22. The object of claim 21, further including a fabric material extending between the first and second panels, with the rod positioned above the fabric material.

23. The object of claim 21, further including a fabric roof extending between the first and second panels, with the rod positioned above the fabric roof.

24. The object of claim 21, wherein the first panel further includes a frame retaining sleeve for retaining the frame member of the first panel, with the frame retaining sleeve attached to the material of the first panel.

25. The object of claim 21, wherein the first and second panels are parallel to each other.
