  • This device has the disadvantage that the aesthetic impression of the picture can be impaired by the eyelets and, in addition, a very high installation effort is necessary to attach the picture.
  • the present invention has for its object to provide a presentation system that overcomes the disadvantages mentioned above.
  • the holding element is constructed from at least one elastic element, the elastic element being substantially rigid in a first transverse direction to the longitudinal fiber of the elastic element and so flexible in a further transverse direction to the longitudinal fiber that the elastic element can be rolled up and / or is foldable, a allows the holding element to be placed in the smallest space. Nevertheless, the holding element can fully fulfill a carrying function for the flat medium when rolled up or unfolded. With appropriate alignment (the elastic element is to be arranged so that the weight acts in the transverse direction to the longitudinal fiber, in which the elastic element is essentially rigid), the supporting function is fully fulfilled.
  • Holding element holding elements, which have very long lengths when installed, can be packed together to a very small size for transport purposes. It can be brought out very quickly from the compactly collapsed state to the installed state; it is not necessary, as in the case of devices according to the prior art, to arrange a large number of rods one behind the other or to join them together. This drastically reduces assembly costs and assembly times.
  • Foldability of the holding element or the elastic element also has the advantage that any intermediate lengths of the holding element can be set exactly with very little effort (in the case of a plurality of rods, any intermediate dimensions cannot be achieved without, for example, sawing up a single rod).

  • the elastic elements arranged opposite one another are surrounded by a flexible sheath.
  • a further advantageous embodiment provides that a plurality of elastic elements are coupled to one another in such a way that an essentially bending-resistant holding element results.
