<p>Reversibly expanding covering elements (50) for truss structures made up of scissor-assemblies (52, 54, 56) that are connected together by hub elements structures (57, 58, 59). These covering elements are comprised of a folded sheet of flexible material such as cardboard or a plastic sheet, or alternatively, comprised of planar panels that are hinged together. As the truss structure expands and contracts, the covering element is compressed and expanded along with it (figures 5-7).</p> |
