An den Ausgängen abgegrenzter Bereiche sind Sende-/Empfangs-Anlagen angeordnet. Die akustomagnetischen Warensicherungselemente erzeugen im Bereich der Sendeanlagen eine Resonanzfrequenz, die von den Empfangsanlagen detektiert werden kann.

Die Erfindung umfaßt auch solche Anwendungen.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.

Vorbekannte AM-Etiketten bestehen aus einem Kunststoffgehäuse, einem Metallplättchen und einem Magnetplättchen. Das Magnetplättchen ist mit einer Nord-Südpolung versehen und das Metallplättchen in exakt festgelegtem Abstand zu diesem positioniert. Auch die Dimensionen der beiden Plättchen sind exakt vorgegeben. Die Waren-Sicherungselemente der akustomagnetischen (AM) Systeme umfaßen üblicherweise ein etikettartiges Kunststoffgehäuse, in welchem ein Metallplättchen und ein Magnetplättchen eingebracht sind. Das Magnetplättchen weist eine Polarisierung auf, wodurch das Ausschwingverhalten des Metallplättchens verstärkt und in bezug auf eine Frequenz optimiert wird. Die räumliche Anordnung der Elemente ist festgelegt und unterliegt extremen Toleranzen. Die Toleranzen liegen im Bereich von zehntel Millimetern.Known 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.
Ein besonderer Nachteil der vorbekannten Warensicherungsetiketten besteht darin, daß sie wegen der Notwendigkeit des räumlichen Schwingens einen dreidimensionalen Funktionsbereich haben. Aus diesem Grunde sind die Etiketten sehr leicht manipulierbar, Darüber hinaus haben sie trotz Miniaturisierung noch eine beachtliche Größe. Es handelt sich um Plättchen mit Ausdehnungen von etwa 1 x 4 x 0,3 cm und sind somit nicht für alle Sicherungsbereiche geeignet. Darüber hinaus weisen sie ein bewegliches Element auf, welches natürlich mechanisch gestört werden kann. Die Empfindlichkeit liegt in engen Grenzen und erfordert sehr starke Sende-/Empfangsanlagen oder sehr enge Abstände von Sender und Empfänger. Darüber hinaus weisen vorbekannte Etiketten keine Langzeitstabilität auf Durch magnetische Veränderungen im üblichen Anwendungsbereich verändert sich die Resonanzfrequenz. Mit zunehmender technologischer Anwendung, beispielsweise Computermonitore, Deaktivierungseinheiten und dergleichen unterliegen die Etiketten ständiger Beeinflussung. Wegen der Notwendigkeit der beweglichen Anordnung ist die Integration vorbekannter Warensicherungselemente in kleindimensionierte Körper nicht möglich.There is a particular disadvantage of the previously known goods security labels in that they unite because of the need for spatial vibration have three-dimensional functional area. This is why the labels are very easy to manipulate, moreover they still have miniaturization a considerable size. These are platelets with dimensions of approximately 1 x 4 x 0.3 cm and are therefore not suitable for all security areas. About that In addition, they have a movable element, which of course is mechanical can be disturbed. The sensitivity is within narrow limits and requires a lot strong transmission / reception systems or very close distances from transmitter and Receiver. In addition, previously known labels have no long-term stability due to magnetic changes in the usual area of application the resonance frequency changes. With increasing technological Application, for example computer monitors, deactivation units and The labels are subject to constant influence. Because of the The integration of prior art is necessary for the movable arrangement Anti-theft elements in small-sized bodies not possible.
Ausgehend vom vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Warensicherungselement bereitzustellen, welches bei geringem wirtschaftlichen Fertigungsaufwand miniaturisierbar ist und darüber hinaus in kleinste und vor allen Dingen variierbare Gehäuseformen integrierbar ist. Die Störbarkeit soll reduziert werden und eine mutwillige Deaktivierung ausgeschlossen werden. Darüber hinaus soll die Detektionsgröße erweitert werden, so daß die Antennen der Sende-/Empfangs-Anlagen verkleinert und/oder die Abstände vergrößert werden können.Starting from the known prior art, 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. In addition, 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.
Zur technischen Lösung dieser Aufgabe wird mit der Erfindung vorgeschlagen ein Warensicherungselement zur Verwendung in Verbindung mit akustomagnetischen Sende-/Empfangs-Systemen, bestehend aus einem stabförmigen Ferritelement, wenigstens einer Spule in Form einer auf das Ferritelement aufgebrachten Kupferdraht-Wicklung und einem zur Spule parallel geschalteten Kondensator. To solve this problem technically, 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.

Der Durchmesser des Kupferdrahts, das Ferrit-Material und die Kapazität des Kondensators lassen sich in bezug auf die gewünschte Resonanzfrequenz aufeinander abstimmen, so daß sich mit geringem Aufwand auch sehr enge Toleranzen einhalten lassen. Der Grad der Miniaturisierung hängt nurmehr von der erforderlichen Detektionsgröße ab. So lassen sich Längen < 2,5 cm und Durchmesser < 5 mm erzielen. Der Kondensator kann örtlich parallel zum Ferritkern angeordnet werden oder an einem der Kopfenden des Ferritkerns.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.
Darüber hinaus lassen sich vorteilhafterweise die Charakteristika des Warensicherungselements, beispielsweise Abstrahlcharakteristika, durch die Form des Querschnitts des Ferrit-Materials einstellen. Besonders geeignet sind in Stranggießverfahren und dergleichen gefertigte Ferrit-Material-Stäbe mit nahezu beliebigen Querschnittsformen, beispielsweise stern-, dreieck-, viereck-, fünfeck-, trapezförmig und dergleichen.In addition, the characteristics of the Goods security element, for example radiation characteristics, through the shape of the cross section of the ferrite material. 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.
Insbesondere bietet das erfindungsgemäße Warensicherungselement die zusätzlichen Möglichkeiten eines modularen Aufbaus und der Verwendung von Schaltelementen. So kann in der Verbindung zwischen Kondensator und Spule wenigstens ein Schaltelement angeordnet sein, wobei vorzugsweise miniaturisierte Schaltelemente wie Readkontakte und dergleichen einsetzbar sind. Dadurch läßt sich das an sich nicht deaktivierbare Warensicherungselement aktivieren und deaktivieren. Auch können Umschaltelemente vorgesehen sein, beispielsweise um den Kondensator auf unterschiedliche Spulenlängen oder verschiedene Spulen zu schalten. Dadurch werden die Frequenzbereiche variierbar und insbesondere auch individualisierbar. So können bestimmten Waren, Warengruppen oder auch Vorgängen bestimmte Frequenzen zugeordnet werden, was den Einsatz der erfindungsgemäßen Warensicherungselemente auch in Produktionstechnologien ermöglicht. So können beispielsweise in industriellen Fertigungsprozessen einzubauende Einheiten mit entsprechenden Warensicherungselementen mit individualisierter Frequenz versehen werden, so daß auch nach Fertigstellung einer Gesamteinheit detektierbar ist, ob einzelne Baugruppen eingebaut wurden oder nicht, und welche. In particular, the security device according to the invention offers the additional possibilities of a modular structure and the use of Switching elements. So in the connection between capacitor and coil 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. As a result, 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.
