Patent number: 7357140Abstract: A collapsible structure comprises a first frame member including first and second segments hingedly interconnected with each other allowing the collapsible structure to have a collapsed position and an expanded position. The collapsible structure further comprises a second frame member hingedly connected to the first frame member. The second frame member includes first and second segments hingedly interconnected with each other. A hinge member is employed to hingedly connect the first segment and the second segment. At least one of the first and second frame members includes a closed-loop configuration.Type: GrantFiled: March 30, 2004Date of Patent: April 15, 2008Assignee: Best Tide Manufacturing Co., Ltd.Inventors: Wan-Sing Chu, Lai-Ha Wu

Patent number: 7252107Abstract: 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.Type: GrantFiled: November 18, 2005Date of Patent: August 7, 2007Assignee: Best Tide Mfg. Co., Ltd.Inventors: Wan-sing Chu, Lai-Ha Wu

Publication number: 20070006910Abstract: A collapsible structure includes a first frame member defining a base of the structure and a second frame member defining a top of the structure. A piece of foldable material is attached to and extends between the first and second frame members. A plurality of foldable frame supporters is mounted on the piece of foldable material whereby folding of the frame supporters drives the first and second frame members towards a superimposed and collapsed position, and unfolding of the frame supporters drives the first and second frame members towards a spaced apart and expanded position. The collapsible structure can be in the form of a baby bed, a play pen, an igloo or a teepee.Type: ApplicationFiled: July 5, 2006Publication date: January 11, 2007Inventors: Wan-Sing Chu, Lai-Ha Wu
