Definitions

  • the invention relates to a goods security element for acustomagnetic security systems, with an assembly arranged in a housing and comprising at least one magnetic element and a metal plate, the magnetic element being formed by the arrangement of a magnetic film polarized in the north pole or south pole orientation,
  • Such goods security elements also called AM labels, which can be used in so-called acustomagnetic systems using acustomagnetic technology, are known per se and are used extensively. They are used to identify goods on which such labels are applied or in which such labels are inserted.
  • AM labels consist of a plastic housing, a metal plate and a magnetic plate.
  • the magnetic plate has a north-south polarity and the metal plate is positioned at a precisely defined distance from it.
  • the dimensions of the two plates are also precisely specified. The tolerances are in the range of tenths of a millimeter.
  • Acustomagnetic system locks consisting of transmitter and receiver units, record the resonance at a frequency of approximately 58 kHz of such labels and trigger. In order not to trigger such labels, large alternating currents are generated by large copper coils, which erase the north-south pole structure located on the magnetic stripe. The acustomagnetic system locks no longer respond.
  • a security device in which the magnetic element is formed by arranging two magnetic materials with high coercivity at opposite ends of a magnetizable strip, the two magnetically high coercive materials being arranged so that they are a single one Induce pole pair alignment.
  • the present invention is based on the above.
  • the prior art is based on the object of providing an article security element which largely prevents manipulation without increasing the structural shape.
  • the invention further develops a security device of the generic type in that it cannot be deactivated, that is to say is designed to be permanently activated.
  • this object is achieved in that a strip (5) of the magnetic film polarized in the north pole orientation and a strip (6) of the magnetic film polarized in the south pole orientation are introduced on opposite sides of the article security element (1).
  • flexible magnetic strips one with a north pole orientation and one with a south pole orientation, arranged on opposite sides of the label, can be adjusted together with the metal plate to a frequency of approximately 58 kHz.
  • the dimension of the magnetic strips and the distance are opposite the metal plate essential.
  • Such permanently activated labels are therefore particularly suitable for systems in which the security element remains within a security area.
  • Special fuse housings so-called safers, can therefore be provided with labels according to the invention, so that the safer labels can no longer be manipulated. This results in increased security.
  • the designs are not enlarged, but miniaturizations are possible. The economic manufacturing effort remains low.
  • FIG. 1 to 3 show an exemplary embodiment for an article security element 1.
  • This consists of a carrier 2 in which the metal plate 3, for example so-called metal glass, is inserted.
  • the carrier 2 has a cross section with rounded longitudinal edges.
  • a frame 4 is positioned on a surface of the carrier, preferably as an assembly aid.
  • Magnets 5 and 6 are arranged diagonally opposite one another. These are the strips of a flexible film with appropriate polarization.
  • the dimensions of the article security element 1 essentially correspond to the dimensions of the article security element known per se, so that these can be replaced without further notice, without the need for new devices.

Abstract

L'invention concerne un élément de sécurité pour marchandises, pour systèmes de sécurité acoustomagnétiques, qui comporte un composant disposé dans un boîtier, présentant au moins un élément magnétique et une plaquette métallique. Pour que cet élément de sécurité soit, sans agrandissement notable de sa forme, protégé contre des manipulations, en particulier contres des désactivations par de forts champs magnétiques, il est proposé, selon l'invention, que l'élément magnétique soit formé par un film magnétique polarisé dans le sens pôle nord ou pôle sud.
