Abstract: 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.

Abstract: A collapsible support frame includes a plurality of segmented legs pivotally connected to an inner surface of a collar, and are held together by an elastic cord. The legs pivot between a folded position and an deployed position. In the folded position, the legs segments form a bundle to facilitate storage or transport. Portions of the legs segments may seat within leg seats formed in the outer surface of the collar. In the deployed position, the legs pivot to contact leg support seats formed at angles in an inner surface of the collar. After contact, each leg extends in a different direction supported by its respective leg support seat. The elastic cord provides tension that keeps the leg segments together in the deployed position, and prevents the leg segments from becoming lost or separated in the folded position.

Abstract: A collapsible support frame includes a plurality of frame structures each having frame members joined together by a tension cable. A locking mechanism pivotably connects the frame structures and allows a user to move the frame structures between a folded position and an unfolded position. In the unfolded position, the frame structure is locked open and may carry a load. In the folded position, the frame structure is collapsed to form a bundle. A slack control member may provide tension to the tension cable when the support frame is unfolded, and to control slack in the tension cable when the support frame is folded.
