<p>Surfaces between the uprights accommodate the items, and are supported from the upright by profiled transverse members, all components being of cardboard. The members can consist of double-skinned sleeves joined to each other by bridge-pieces. They can be of rectangular cross-section in the unassembled state, while each member and bridge-piece can together form a slot into which a protruding edge on the supported surface fits. Protrusions can be provided at the member ends for joining to the uprights.</p> |
