  • Patent number: 6836988
    Abstract: The present invention relates to an arrangement enabling edge-to-edge joining, by means of a magnetic attractive force, of a first edge portion 811a) of a first panel (11) in a display system to a second edge portion (12b) of a second panel (12), a first magnetised strip (11e) being applied to said first edge portion (11a) and a second magnetised strip (12b) being applied to said second edge portion (12b). The magnetised strips (11e, 12d) are assigned such magnetisation directions (s-n; n-s) that, in a position where the edge portions are in proximity and/or co-operating with each other, they assume a position attracted to each other. Said strips (11e, 12d) consist of a material different from the material of the panel (11, 12). The modulus of elasticity and the thickness (2600 MPa; 0.2 mm) of said panel (11) and the modulus of elasticity and the thickness (100 MPa; 0.

  • Patent number: 5778580
    Abstract: An image display unit includes a sheet-like image carrier, the carrier having at least one edge, the carrier being bendable. The image display unit also includes a coupling device, the coupling device including at least a first and a second part, the first part of the coupling device being disposed proximate the at least one edge of the carrier and the second part of the coupling device being attached to the carrier at a distance from the at least one edge, the first and second parts of the coupling device defining a first carrier section, the first and second parts of the coupling device each being vertically-oriented strips and having first and second coupling structures, respectively, the first and second coupling structures being engageable with each other. The carrier has a second carrier section.

  • Patent number: 5355555
    Abstract: A hinge strip forms a hinge arrangement comprising a plurality of edge related segments, oriented between two mutually adjacent elements, normally in the form of two flat panels, the strip having at least one surface coated with a respective adhesive layer for adhesion to at least one of an edge region and an edge surface of a respective element, the hinge strip being divided along its edge surface into segments by exposing a number of mutually spaced segments separating weakenings, which are arranged to extend transversely to a longitudinally extending center line or a hinge rotation line, each segment having a nonadhesive surface region which is positioned between two adjacent adhesive surface regions, a non-adhesive surface region of adjacent edge segments being located on alternating sides of a hinge line.

  • Patent number: 4825930
    Abstract: The present invention relates to a hinge arrangement for hinging and coupling a first element (1) to a second element (2), of which elements at least one includes an internal cavity (1a) adjacent the hinge location (3) and a hinge member (4) which functions as a pivot pin or pivot arm and also holds the elements together. The elements (1) provided with cavities (1a) have formed therein one or more slots (5) which are oriented at right angles to the rotational axis (6) of the pivot arm or pin. The hinge member (4) is intended for insertion through respective slot for retention in the cavity (1a). The hinge member (4a) is retained in its respective slot through the agency of a bearing and guide surface provided on the member and intended for co-action with a corresponding bearing and guide surface provided in the cavity (1a) in the immediate vicinity of the slot (5).
