A collapsible frame for supporting a fabric structure includes frame members which themselves can be plastically deformed as well as folded around one or more hinges. The ductile frame members can be deformed plastically to hold the fabric structure in a predetermined orientation. When not in use, the frame can be folded around the hinges disposed between the individual frame members. Folding the frame around the hinges significantly reduces the possibility of the ductile frame members work-hardening and experiencing a metal fatigue failure. 1141014. A flexible frame () for supporting a fabric structure () , said frame () comprising:{'b': ['16', '16', '16', '16', '16', '38', '40'], '#text': 'a plurality of elongated frame members (A, B, C, D), each of said plurality of elongated frame members () having a first end () and second end (); and'}{'b': ['18', '18', '18', '18', '18', '18', '18', '18', '42', '44', '42', '44'], '#text': 'a plurality of articulating joints (A, B, C, D), each of said plurality of articulating joins (A, B, C, D) comprising a hinge (, ) that rotates from an inline position to a rotated position in which the hinge (, ) is rotated 180° from the inline position;'}{'b': ['16', '16', '16', '16', '38', '18', '18', '18', '18', '40', '18', '18', '18', '18'], '#text': 'each of said plurality of elongated frame members (A, B, C, D) being attached at a first end () to one of said plurality of articulating joints (A, B, C, D) and attached at a second end () to another one of said plurality of articulating joints (A, B, C, D);'}{'b': ['16', '16', '16', '16', '10'], '#text': 'wherein said plurality of elongated frame members (A, B, C, D), are made of a ductile material that can be deformed plastically into a deformed shape and substantially retain the deformed shape and wherein said fabric structure () can be folded to a substantially flat configuration by rotating said plurality of articulating joints.'}2. The flexible frame of claim 1 , wherein:{'b': ['18', ...
