发明名称 Collapsible frame structures
摘要 A collapsible frame comprises a plurality of frame members joined together by a flexible tension cable. In one embodiment, the individual frame members are also joined together by an elastic cord to facilitate assembly. The tensioning member includes an arcuate cable track and is rotatably connected to the frame. Relative rotation of the frame and tensioning member in a first direction tightens the tension cable, while relative rotation of the frame and tensioning member in a second direction loosens the tension cable.
