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.

What is claimed is: 1. A foldable enclosure structure comprising: a first supporting frame including a first attachment point and a second attachment point; a second supporting frame pivotable between a collapsed position and an expanded position about an axis that extends through the first and second attachment points of the first supporting frame for generally vertical orientation; a fabric cover supported by the first and second supporting frames and defining an enclosure in the expanded position of the second supporting frame; at least one cylindrical structure attached to at least one side of at least one of the supporting frames, the at least one cylindrical structure having a longitudinal axis that is substantially parallel to the axis of the second supporting frame; and at least one reinforcement frame positioned along a girth of the first supporting frame and the second supporting frames in the expanded position for generally horizontal orientation. 2. The foldable enclosure structure of claim 1 wherein the at least one cylindrical structure is four cylindrical structures respectively attached to four sides of the supporting frames. 3. The foldable enclosure structure of claim 1 wherein each of the first and second supporting frames has a folded orientation and an unfolded orientation and is twisted and folded to form concentric rings in the folded orientation. 4. The foldable enclosure structure of claim 1 wherein the reinforcement frame is fixed to the first and second supporting frames by a releasable fixing mechanism. 5. The foldable enclosure structure of claim 4 wherein the releasable fixing mechanism comprises Velcro tapes. 6. The foldable enclosure structure of claim 1 wherein the reinforcement frame is semi-rigid and is positioned at the inner sides of the first and second supporting frames in the expanded position. 7. The foldable enclosure structure of claim 1 further comprising an abutment frame provided horizontally at the bottom of the first and second supporting frames in the expanded position and vertical orientation of the axis. 8. The foldable enclosure structure of claim 7 wherein the abutment frame is fixed to the first and second supporting frames by a releasable fixing mechanism. 9. The foldable enclosure structure of claim 8 wherein the releasable fixing mechanism comprises Velcro tapes. 10. The foldable enclosure structure of claim 1 further comprising a conical structure provided on top of the at least one cylindrical structure. 11. The foldable enclosure structure of claim 1 wherein the first and second supporting frames each have a generally rectangular shape, and the enclosure defined by the fabric cover has a cubic shape in the expanded position. 12. The foldable enclosure structure of claim 1 wherein the at least one cylindrical structure is attached to the at least one side of the supporting frames by releasable fixing mechanism. 13. The foldable enclosure structure of claim 12 wherein the releasable fixing mechanism comprises Velcro tapes. 14. The foldable enclosure structure of claim 1 wherein at least one of the first and second supporting frames comprises a closed-loop configuration. 15. The foldable enclosure structure of claim 1 further comprising a coupling mechanism that couples the first supporting frame to the second supporting frame. 16. The foldable enclosure structure of claim 1 further comprising at least one opening on the fabric cover. 17. A foldable enclosure structure comprising: a first supporting frame including a first attachment point and a second attachment point; a second supporting frame pivotable between a collapsed position and an expanded position about an axis that extends through the first and second attachment points of the first supporting frame for generally vertical orientation; a fabric cover being supported by the first and second supporting frames for defining an enclosure in the expanded position and generally vertical orientation; four cylindrical structures respectively attached to four sides of the supporting frames that are generally vertical in the generally vertical orientation; and at least one reinforcement frame along a girth of the first supporting frame and the second supporting in the expanded position and generally vertical orientation for generally horizontal orientation, wherein each of the first and second supporting frames has a folded orientation and an unfolded orientation that is twisted and folded to form concentric rings in the folded orientation wherein each of the cylindrical structures has a longitudinal axis that is substantially parallel to the axis of the second supporting. 18. The foldable enclosure structure of claim 17 further comprising an abutment frame horizontally at the bottom of the first and second supporting frames in the expanded position and generally vertical orientation.
