Abstract: 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.

Abstract: A foldable enclosure structure containing a fabric cover defining a desired shape when expanded to an expanded position; a first supporting frame fixedly attached to the cover and a second supporting frame provided within the cover and rotatably coupled to the first frame such that the second frame is movable between a collapsed position and an expanded position. The second frame is superposed over the first frame in the collapsed position for ease of storage, but is rotated axially to intersect with the first frame in the expanded position to prop up the cover to the desired shape. To ensure that the structure is stable in the expanded position, fixing means is/are provided for fixedly attaching the second frame to the first frame in the expanded position.

Abstract: A portable and reversible collapsible structure that contains a bottom panel and a plurality of side panels. Each of the side panels contains a fabric material attached to at least one frame with each frame foldable between an expanded position and a recoiled position. At least two side panels are hingedly connected to opposing sides of the bottom panels. At least one detachable side panel is further attached to the bottom panel and in a position that is in between the opposing side panels. The connection between the detachable side panel and the bottom panel is reversible and detachable by a user. The connection between the detachable side panel and one of the opposing side panels is also reversible according to the needs of a user.
