Definitions

  • the present invention relates to an article security element for use in Connection with acustomagnetic transmission / reception systems.
  • Such acustomagnetic systems using acustomagnetic Technology is known per se and is used particularly in the field of Goods security used. There are delimited areas at the exits Transmitting / receiving systems arranged.
  • the acustomagnetic Anti-theft devices generate a in the area of the transmitter Resonance frequency that can be detected by the receiving systems. This Detection can then be used for different purposes for example for emitting signals.
  • Goods security element in the sense of However, the present invention is not intended to apply the corresponding elements to the Limit the purpose of securing goods. Also personal access rights and the same security-relevant applications can be achieved with such Realize systems and elements.
  • the invention also includes such Applications.
  • AM labels consist of a plastic housing, a Metal plate and a magnetic plate.
  • the magnetic plate is with one Provide north-south polarity and the metal plate at a precisely defined distance positioned to this. The dimensions of the two plates are also exact given.
  • the goods security elements of the acustomagnetic (AM) Systems usually include a label-like plastic housing in which a metal plate and a magnetic plate are introduced.
  • the Magnetic plate has a polarization, which causes the swing-out behavior of the metal plate is amplified and optimized with respect to a frequency.
  • the spatial arrangement of the elements is fixed and subject to extreme Tolerances. The tolerances are in the range of tenths of a millimeter.
  • the object of the invention is to provide an article security element which can be miniaturized with little economic production effort and, moreover, can be integrated into the smallest and, above all, variable housing shapes.
  • the interference is to be reduced and a deliberate deactivation should be excluded.
  • the detection size should be expanded so that the antennas of the transmitting / receiving systems can be reduced and / or the distances can be increased.
  • the invention proposes an article security element for use in connection with acustomagnetic transmission / reception systems, consisting of a rod-shaped ferrite element, at least one coil in the form of a copper wire winding applied to the ferrite element and one connected in parallel to the coil Capacitor.
  • the article security element according to the invention can be used in industrial Mass production with little economic effort in extremely miniaturized Manufacture construction.
  • the diameter of the copper wire, the ferrite material and the Capacitance of the capacitor can be adjusted in relation to the desired one Match the resonance frequency to each other so that it can be done with little effort also keep very tight tolerances.
  • the degree of miniaturization depends only depends on the required detection size. This allows lengths ⁇ 2.5 cm and diameter ⁇ 5 mm.
  • the capacitor can be locally parallel to the Ferrite core are arranged or at one of the head ends of the ferrite core.
  • the characteristics of the Goods security element for example radiation characteristics, through the shape of the cross section of the ferrite material.
  • the characteristics of the Goods security element for example radiation characteristics
  • the characteristics of the Goods security element are particularly suitable in Continuous casting process and the like manufactured ferrite material rods with almost any cross-sectional shapes, for example star, triangle, square, pentagonal, trapezoidal and the like.
  • the security device offers the additional possibilities of a modular structure and the use of Switching elements.
  • at least one switching element can be arranged, preferably miniaturized Switching elements such as read contacts and the like can be used. This leaves activate the non-deactivatable goods security element and deactivate.
  • Switching elements can also be provided, for example by the capacitor to different coil lengths or different coils switch.
  • the frequency ranges can be varied and in particular also customizable. So certain goods, product groups or even Processes are assigned certain frequencies, which is the use of Goods security elements according to the invention also in production technologies enables. For example, in industrial manufacturing processes units to be installed with appropriate security devices individualized frequency, so that even after completion an entire unit can detect whether individual modules have been installed or not and which ones.
  • the miniaturized security element in integrate any housing shape.
  • the invention provides a new type of article security element, which with little economic effort in the context of industrial Mass production can be manufactured with close tolerances. It can be vary in design and frequency and is practically impossible to manipulate. Due to the possibility of modular construction using Switching elements can generate different functional states.
  • Modular structure in the sense of the present invention also means that Individual modules are made available in modules and only for the desired function to be assembled.
  • the capacitor can be used as a pluggable element be added to the assembly of ferrite core and coil. This results in also the possibility of a different spatial arrangement, which the Variation in terms of housing, miniaturization and area of application enlarged.
  • the article security element 1 consists of a ferrite core 2, a copper coil 3, a capacitor 4 and a connection 5 between Capacitor 4 and copper coil 3.
  • the ferrite core 1 is rod-shaped and can have a round or angular cross section to have.
  • the copper coil 3 is in the embodiment shown as a double winding shown, so that at one end of the ferrite core 2 both coil ends to build the connection 5 with the capacitor 4 are available.
  • the coil 10 is around Ferrite core 9 constructed as a single winding, so that the two free ends at the two ferrite core ends for connection to the capacitor 11, which is in parallel is arranged to the ferrite core, are available.
  • the capacitor is always connected in parallel to the coil. in the 3 is in a connection between the capacitor 11 and coil 10, a miniature switch 12 is arranged so that the Goods security element can be switched on and off.
  • Fig. 2 shows a practical application for a security device.
  • a security device For example, to secure glasses 6, one is placed in a miniature housing 7 Arranged goods security element in the embodiment according to FIG. 1 or Fig. 3 arranged and fastened to the glasses by means of fastenings 8.
  • Conventional goods security elements cannot be used for goods such as glasses back up easily.
