  • Patent number: 6386359
    Abstract: The invention comprises an openable and closable storage unit (1) adapted so as to be capable of enclosing a folded-up display unit (2), consisting of one or more stand parts and one or more information-carrying sheets, screens or the like, first and second end-wall parts (11, 12) which belong to a wall part (10), said wall part (10) being arranged to, in cross section, form a cross-sectional area following one or both said end-wall parts (11, 12). A first storage space (5) is given a circular or in any case essentially circular cross section by means of part-circular units (7) which are formed in plane wall sections (10b) or applied thereto. A second storage space (6) is given a semi-circular or in any case essentially semi-circular cross section by means of units (8) which are formed in or next to said plane wall sections or attached thereto.

  • Patent number: 5957182
    Abstract: The invention relates to a display unit end section, wherein the end section has a closed, curved cross-sectional shape and is comprised of a bendable sheet having mutually opposite edge portions which are each provided with a first coupling element forming part of the respective two-part coupling mechanism. Respective second corresponding coupling elements of the two-part coupling mechanism are attached to a rail. The rail includes a first coupling element of a further two-part coupling mechanism adapted for coaction with a corresponding second coupling element placed on the edge-part of the display unit.
