Patent number: 7111634Abstract: A self-erecting structure includes a series of fabric panels each tautly spread by a length of steel wire or other resiliently flexible, filiform material. The steel wire may form a closed loop, an open loop or a mere arc. The wire is selectively inserted into at least two of several pockets or fabric straps positioned around the periphery of the panel. The selection of the wire-holding pockets or straps defines the shape of the spread-out panel. Parts of the fabric which are not encompassed by a wire are held folded over it and against the spread-out portion. The shape of the structure can be quickly modified by repositioning of the wires.Type: GrantFiled: December 4, 2002Date of Patent: September 26, 2006Assignee: Carillon International LimitedInventor: Wai Hang Louie

Patent number: 7077147Abstract: A collapsible and foldable canvas structure has only two structural panels, each formed by a piece of fabric material spread across and secured about its periphery to a resiliently flexible wire frame. One of the panels is laid flat on the ground or other supporting surface; the other rises vertically from a median section of the first and is held by straps or by sheets of fabric material not structured or framed by any wire but joined to the top of the vertical panel and to the outer edges of the flat one. A window cut on the center of the vertical panel provides access from one side to the other. The panels are substantially commensurate. They can be brought back together and twisted along with the remaining components of the structure into a compact package.Type: GrantFiled: January 3, 2003Date of Patent: July 18, 2006Assignee: Genevieve ShiuInventors: Wai Hang Louie, Genevieve Shiu, Robert Hsu
