Abstract
In a hinged structure in which two substantially cylindrical supports (1,2) are hinged together by means of one or more hinges so that they are parallel and closely adjacent, the or each hinge comprises at least two members (3,4) each made of resiliently flexible strip material, each member being S-shaped, passing partially around each support and together with one of the other members forming a letter "x" or figure "8" configuration as seen in a direction along the supports, the ends of the strips being crimped between plates (6,7,8,9) having opposed complementarily profiled surfaces, which plates are attached to the supports or extensions (14,15) of them whereby the strips are tensioned round the supports.
