发明名称 Quickly erectable, quickly collapsible, self supporting portable structure
摘要 Quickly erectable, quickly collapsible, self supporting portable structures (100) that are self expandable with little or no effort by the user, which in their fully expanded upstanding configuration are self supporting. The fully expanded upstanding structure can be quickly collapsed into a stack of side members (145) and then coiled into a pack (160) with little effort by the user. The structures can be used as tents, shelters, pavilions and automobile carports. In general the portable structures have a set of at least three side members (102) each having a flexible frame (106), a side panel (108), a pocket (110) joined to the panel by stitching (112). The frame causes the side members to be self expandable. Side members are hinged together by stitching (130). A floor member (104) sewn to the bottom (124) of each side member holds the structure in the upstanding position.
