ABSTRACT:
A structural member capable of being coiled by bending the member in one direction and being uncoiled by bending it in the other direction to form a frame member which is relatively rigid. This member is constructed by forming an elongated one-piece body of suitably flexible material, such as polypropylene, by extrusion. Strong, flexible threads are embedded in one side of the body and a passageway is formed extending lengthwise through the body during the extrusion. The body member is then cut or notched transversely at locations distributed along the length of the body member. Each cut extends inwardly from the side of the body member oppisite said one side and has a bottom near but spaced apart from said one side. Sheer members of suitably strong material are inserted in one end of the passageway in end-to-end relationship until they extend substantially the length of the body member and are properly positioned. Each sheer member traverses one of the cuts when the structural member is uncoiled to absorb sheer forces at the cut.
