Collapsible structure
A collapsible structure having a first fabric-covered frame defining a first side panel, a second fabric-covered frame defining a second side panel, a fabric sheet mounted on and extending along the first and second fabric-covered frames; and a plurality of frame supports mounted on the fabric sheet whereby folding of the frame supports drives the first and second side panels towards a collapsed and superimposed position, and unfolding of the frame supports drives the first and second side panels towards a spaced apart and expanded position, and wherein the first and second side panels in the collapsed and superimposed position can be twisted and folded into a compact configuration.
1. A collapsible structure comprising:
(a) a first fabric-covered frame defining a first side panel;
(b) a second fabric-covered frame defining a second side panel;
(c) a fabric sheet mounted on and extending along said first and second fabric-covered frames; and
(d) a plurality of frame supports mounted on said fabric sheet whereby folding of said frame supports drives said first and second side panels towards a collapsed and superimposed position, and unfolding of said frame supports drives said first and second side panels towards a spaced apart and expanded position, and wherein said first and second side panels in said collapsed and superimposed position are foldable into a compact configuration;
wherein at least one of said frame supports comprises a first section, and a second section pivotally connected to said first section by a pivoting mechanism, said first and second sections being in the form of a tube or rod; and
wherein each of said first and second fabric-covered frames is made of a flexible strip or rod being formed into a loop, the first and second fabric-covered frames being twistable into a figure-8 shape.
2. The structure according to claim 1 wherein each of said first and second fabric-covered frames has an elongated ground-engaging section.
3. The structure according to claim 1 wherein each frame support is received within a fabric sleeve that is fastened to said fabric sheet.
4. The structure according to claim 3 wherein the opposite free ends of each frame support are fastened within the opposite ends of each fabric sleeve respectively, and said opposite ends of each fabric sleeve define two flexible links whereby each frame support is flexibly connected to said first and second fabric-covered frames.
5. The structure according to claim 4 wherein each fabric sleeve has an opening through which said pivoting mechanism of each frame support can be exposed whereby folding and unfolding of each frame support can be facilitated.
6. The structure according to claim 1 wherein each frame support is received within a fabric sleeve that is fastened to said fabric sheet.
7. The structure according to claim 1 wherein said first and second side panels are generally upright and parallel to each other in said expanded position.
8. The structure according to claim 1 wherein said first and second side panels are disposed at an angle to each other and tapering upwards in said expanded position.
9. The structure according to claim 1 further comprising a third frame located between said first and second fabric-covered frames and fastened to said fabric sheet.
10. The structure according to claim 9 wherein said first, second and third frames, and said frame supports are made of plastic or metal.
11. The structure according to claim 1 wherein said fabric sheet and said first and second side panels together define an enclosure when said first and second side panels are in said spaced apart and expanded position.
12. The structure according to claim 11 wherein at least one of said fabric sheet and said first and second side panels has an opening through which a player can enter or exit said enclosure.
13. The structure according to claim 1 wherein said structure is a children playhouse.
