Definitions

  • the invention relates to a change holder for an information carrier, which consists of an electrostatically chargeable flat material and the information carrier is held on one side of the change holder by electrostatic adhesion.
  • the electrostatically chargeable flat material consists of a transparent, flexible film, the edge regions of which are held on the interchangeable holder by electrostatic adhesion generated by means of friction.
  • the information carrier that can be placed under this film is thus held indirectly by electrostatic adhesion to the change holder ((DE-GM 80 05 553).
  • Exchange holders of this type or of another type are used for a wide variety of purposes.
  • swap holders with different information are used in department stores to indicate special offers. They can be hung from the ceiling with cords.
  • Attaching and changing Information carriers are more or less complex. Compared to change holders, in which the information carriers are glued on and where the old information carriers have to be removed before attaching a new information carrier, changing the information carriers is more complex than with a change holder of the type mentioned, in which only the film is lifted off old information carriers located underneath must be removed and the new one inserted. But even with such an information carrier, the change is still connected with a series of steps. Changing the information carrier can be hindered by the film to be lifted off.
  • the film covering the information carrier can have a blinding effect. It would be desirable if the information carrier were visible without a covering film, as is the case with glued-on information carriers.
  • the invention has for its object to provide an interchangeable holder for information carriers, which does not require a covering film with easy interchangeability of the information carriers.
  • an electric field is created between the two groups of interlocking cable runs, which is electrostatic attracts rechargeable information carriers.
  • the holding force is sufficient, on the one hand, to hold the information carrier lying flat against the side, on the other hand, it allows the information carrier to be pulled off the side.
  • the information carriers can therefore be replaced without great effort. It is no longer necessary to disassemble the possibly mounted change holder and prepare it for a change of the information carrier. After removing the old information carrier, it is immediately available for the new information carrier.
  • the cable runs should be provided especially in the edge areas of the change holder side, because otherwise the edges of a very flexible information carrier can come loose.
  • An effective electric field can be realized with a clear picture of cable runs if the cable runs intermesh like a comb.
  • the cables can be easily made by printing a conductive paste.
  • the cable runs are in or on a flexible, non-stretchable material, such as paper-like nonwoven fabric made of thermally welded high-pressure polyethylene fibers, which is fastened to a rigid body of the interchangeable holder. Since the printed conductor image is on flexible, non-stretchable material, it is not only easy to produce in the printing process, but also allows the user a different spatial design. He can use a drum or a plate, in particular a flat plate, as a dimensionally stable body.
  • a transformer with rectifiers should be installed in the changeable holder as a direct voltage source, so that a high voltage can be built up. Since practically no energy is required for holding, only a transformer of extremely low power is required.
  • a paper-like non-woven fabric 2 made of thermally welded high-pressure polyethylene fibers is glued to a rectangular, dimensionally stable, flat plate 1.
  • the nonwoven fabric is printed with two groups, comb-like interlocking lines 3, 4 made of a conductive paste, for example silver conductive lacquer. At one corner, the two groups are plated through at positions 5, 6.
  • the individual cable runs 3, 4 are electrically insulated from one another by sufficient mutual spacing.
  • a DC voltage source 7 with an electrical transformer and a rectifier circuit is installed in the box 1 in a box.
  • the transformer can be connected to the network via a connecting cable 8.
  • the DC voltage source 7 has output contacts at points corresponding to the plated-through holes 5, 6.
