Description

Die Erfindung betrifft ein Warensicherungselement für akustomagnetische Sicherungssysteme mit in einem Gehäuse angeordneten Magnetelementen und Metallplättchen gemäß Oberbegriff des Anspruches 1.The invention relates to a merchandise security element for akustomagnetische security systems with arranged in a housing magnetic elements and metal plates according to the preamble of claim 1.

Derartige in sogenannten akustomagnetischen Systemen unter Anwendung akustomagnetischer Technologie anwendbare Warensicherungselemente, auch AM-Etikett genannt, sind an sich bekannt und umfangreich im Einsatz. Sie dienen der Identifizierung von Waren, auf die solche Etiketten aufgebracht oder in die solche Etiketten eingebracht sind.Such merchandise security elements, also called AM labels, which can be used in so-called acoustomagnetic systems using acoustomagnetic technology, are known per se and are widely used. They are used to identify goods on which such labels are applied or in which such labels are inserted.

Vorbekannte AM-Etiketten bestehen aus einem Kunststoffgehäuse, einem Metallplättchen und einem Magnetplättchen. Das Magnetplättchen ist mit einer Nord-Süd-Polung versehen und das Metallplättchen in exakt festgelegtem Abstand zu diesem positioniert. Auch die Dimensionen der beiden Plättchen sind exakt vorgegeben. Die Toleranzen liegen im Bereich von zehntel Millimetern. Akustomagnetische Systemschleusen, bestehend aus Sende- und Empfangseinheiten, erfassen die Resonanz des schwingenden Metallplättchens bei einer Anregungsfrequenz von etwa 58 kHz und lösen aus. Um solche Etiketten nicht zur Auslösung zu bringen, werden durch große Kupferspulen hohe Wechselströme erzeugt, die die auf dem Magnetstreifen befindlichen Nord-Südpol-Struktur löschen. Damit sprechen die akustomagnetischen Systemschleusen nicht mehr an. Allerdings lassen sich solche Etiketten auch sehr leicht manipulieren. Dies erfolgt beispielsweise durch mutwillige Deaktivierung. Es gibt Einsatzbereiche, die besonders diebstahlempfindlich sind, beispielsweise CD-Abteilungen von Warenhäusern, Musikgeschäften und dergleichen. Hier wird anstelle der deaktivierbaren Etiketten ein anderes System verwendet, wobei die Etiketten in sogenannter Safer eingebracht sind, die im Geschäft verbleiben. Aber auch hier lassen sich durch Druckausübung, mechanische Verbiegung oder durch Löschung im oben beschriebenen Sinne die Sicherungssysteme manipulieren.Previously known AM labels consist of a plastic housing, a metal plate and a magnetic plate. The magnetic plate is provided with a north-south polarity and the metal plate positioned at an exactly fixed distance to this. Also, the dimensions of the two plates are specified exactly. The tolerances are in the range of tenths of a millimeter. Akustomagnetische system locks, consisting of transmitting and receiving units, detect the resonance of the vibrating metal plate at an excitation frequency of about 58 kHz and trigger. In order not to trigger such labels, high alternating currents are generated by large copper coils which extinguish the north-south pole structure located on the magnetic strip. The acoustomagnetic system locks are no longer responsive to this. However, such labels are also very easy to manipulate. This is done, for example, by willful deactivation. There are applications that are particularly sensitive to theft, for example, CD departments of department stores, music shops and the like. Here, instead of deactivatable labels another system is used, the labels are placed in so-called safer, which remain in the shop. But here too can be manipulated by pressure, mechanical bending or deletion in the sense described above, the security systems.

Aus der US-PS 4 510 489 ist ein Warensicherungselement bekannt, bei dem das Magnetelement durch Anordnung von zwei magnetischen Materialien mit hoher Koerzitivität an einander gegenüberliegenden Enden eines magnetisierbaren Streifens gebildet wird, wobei die beiden magnetisch hochkoerzitiven Materialien so angeordnet sind, dass diese eine einzelne Polpaar-Ausrichtung induzieren.From the U.S. Patent No. 4,510,489 For example, a merchandise security element is known in which the magnetic element is formed by arranging two high coercivity magnetic materials at opposite ends of a magnetizable strip, the two magnetically highly coercive materials being arranged to induce a single pole pair alignment.

Weiterhin sind beispielsweise aus der DE 298 23 167 U1 Warensicherungseinrichtungen bekannt, bei denen eine flexible Magnetfolie in unterschiedlichen Polausrichtungen im Etikettgehäuse untergebracht wird, so dass auf das Standardmagnetplättchen verzichtet werden kann. Es hat sich hierbei herausgestellt, dass flexible Magnetstreifen, je einer mit einer Nordpol-Ausrichtung und einer mit einer Südpol-Ausrichtung, an gegenüberliegenden Seiten des Etiketts angeordnet, zusammen mit dem Metallplättchen auf eine Frequenz von etwa 58 kHz einjustierbar sind. Hierfür ist die Dimension der Magnetstreifen und der Abstand gegenüber dem Metallplättchen wesentlich. Es hat sich als besonders vorteilhaft herausgestellt ein Magnetfolienstreifen von ca. 1,4 mm Höhe, etwa 1,5 cm Länge und einer Breite von etwa 2 mm. Diese Streifen werden an diagonal gegenüberliegenden Seiten des Etiketts angeordnet. Es hat sich weiterhin herausgestellt, dass sich derartige Etiketten mit herkömmlichen Deaktiviereinheiten nicht mehr deaktivieren lassen. Solche permanent aktivierten Etiketten eignen sich somit besonders für Systeme, bei denen das Sicherungselement innerhalb eines Sicherungsbereiches verbleibt. Es können also spezielle Sicherungsgehäuse, sogenannte Safer, mit erfindungsgemäßen Etiketten versehen sein, so dass die Safer-Etiketten nicht mehr manipulierbar sind. Somit ergibt sich dann eine erhöhte Sicherheit. Dabei werden die Bauformen nicht vergrößert, sondern allenfalls Miniaturisierungen ermöglicht. Der wirtschaftliche Herstellungsaufwand bleibt dabei gering. Allerdings ist die Baugröße dieser Warensicherungselemente immer noch relativ groß, da die Magnetfolienstreifen entsprechende Abmessungen aufweisen und beidseitig benachbart zu dem Metallplättchen angeordnet werden müssen.Furthermore, for example, from the DE 298 23 167 U1 Goods security devices are known in which a flexible magnetic film is accommodated in different polar orientations in the label housing, so that it is possible to dispense with the standard magnetic chip. It has been found here that flexible magnetic strips, one each with a north pole orientation and one with a south pole orientation, are arranged on opposite sides of the label, together with the metal plate can be adjusted to a frequency of about 58 kHz. For this purpose, the dimension of the magnetic strip and the distance from the metal plate is essential. It has been found to be particularly advantageous a magnetic film strip of about 1.4 mm in height, about 1.5 cm in length and a width of about 2 mm. These strips are placed on diagonally opposite sides of the label. It has also been found that such labels can not be deactivated with conventional deactivation units. Such permanently activated labels are thus particularly suitable for systems in which the security element remains within a security area. It is therefore possible to provide special fuse boxes, so-called safers, with labels according to the invention, so that the safer labels can no longer be manipulated. This results in increased safety. The designs are not enlarged, but at best allows miniaturization. The economic production costs remain low. However, the size of this merchandise security elements is still relatively large, since the magnetic film strips have corresponding dimensions and must be arranged on both sides adjacent to the metal plate.

Aufgabe der vorliegenden Erfindung ist es daher, ein Warensicherungselement der gattungsgemäßen Art dergestalt weiter zu bilden, dass die Baugröße des Warensicherungselementes noch einmal reduziert wird und die Detektionseigenschaften dabei nicht beeinträchtigt werden.The object of the present invention is therefore to further develop a merchandise security element of the generic type in such a way that the size of the merchandise security element is reduced again and the detection properties are not affected.

Die Lösung der erfindungsgemäßen Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1 in Zusammenwirken mit den Merkmalen des Oberbegriffes. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the object of the invention results from the characterizing features of claim 1 in conjunction with the features of the preamble. Further advantageous embodiments of the invention will become apparent from the dependent claims.

Die Erfindung geht aus von einem Warensicherungselement für akustomagnetische Sicherungssysteme mit in einem Gehäuse angeordneten Magnetelementen und Metallplättchen. Ein derartiges Warensicherungselement wird dadurch in erfinderischer Weise weiter ausgestaltet, dass in dem Warensicherungselement mindestens ein Magnetelement derart im Randbereich des beispielsweise aus Metglass gebildeten Metallplättchens angeordnet und ausgerichtet ist, dass die Polarisierung des Magnetfeldes des mindestens einen Magnetelementes parallel zur Längserstreckung des Metallplättchens verläuft. Es wurde überraschend festgestellt, dass bei einer derartigen Anordnung des mindestens einen Magnetelementes das Magnetelement die Schwingungsfähigkeit des Metallplättchens verstärkt und damit schon bei Verwendung von allein einem Magnetelement eine sichere Detektion des Warensicherungselementes in entsprechenden Sicherungsschleusen möglich wird. Hierbei ist nicht wie bei den bekannten Warensicherungselementen aus der AM-Sicherungstechnik die Verwendung von zwei Magnetelementen notwendig, wodurch das Warensicherungselement insgesamt kleiner ausgebildet werden kann und das resultierende Gewicht des Warensicherungselementes geringer als bei vergleichbaren Warensicherungselementen, vorteilhafterweise unterhalb von etwa 10 Gramm gehalten werden kann. Damit lassen sich derartige Warensicherungselemente auch an leichten oder leicht beschädigbaren Waren wie etwa Bodyware oder Waren aus Seide oder dgl. dauerhaft befestigen, ohne dass es zu Beschädigungen der Ware kommt.The invention is based on a merchandise security element for acoustomagnetic security systems with magnetic elements and metal platelets arranged in a housing. Such a merchandise security element is further embodied in an inventive manner that in the merchandise security element at least one magnetic element is arranged and aligned in the edge region of the formed for example of Metglass metal plate and aligned that the polarization of the magnetic field of the at least one magnetic element is parallel to the longitudinal extent of the metal plate. It has surprisingly been found that with such an arrangement of the at least one magnetic element, the magnetic element enhances the vibration capability of the metal plate and thus even when using only a magnetic element secure detection of the merchandise security element is possible in corresponding security locks. In this case, the use of two magnetic elements is not necessary as in the known merchandise security elements from AM security technology, whereby the merchandise security element can be made smaller overall and the resulting weight of the merchandise security element can be kept lower than comparable merchandise security elements, advantageously below about 10 grams. Thus, such items securing elements can be permanently attached to light or easily damaged goods such as bodyware or silk or the like, without causing damage to the goods.

In einer ersten vorteilhaften Ausgestaltung kann das mindestens eine Magnetelement in Verlängerung der Längserstreckung des Metallplättchens, insbesondere beabstandet zu dem Metallplättchen angeordnet sein. Hierdurch verläuft das von dem mindestens einen Magnetelement erzeugte Magnetfeld genau in Richtung der Längserstreckung des Metallplättchens und kann daher die Resonanz des Metallplättchens beim Durchtreten einer Sicherheitsschleuse maximal unterstützen. Damit werden die Detektionseigenschaften des Warensicherungselementes wesentlich verbessert bzw. bei einem nur klein bauenden Magnetelement die Detektionseigenschaften erreicht, die sonst nur mit aufwendigeren Warensicherungselementen erzielbar sind. Auch kann durch die Größe des Abstandes eine Beeinflussung der Detektionseigenschaften des Warensicherungselementes vorgenommen werden. Hiebei ist es auch möglich, mehr als ein Magnetelement, vorteilhaft zwei Magnetelemente so relativ zu dem Metallplättchen anzuordnen, dass die zwei oder mehr Magnetelemente in Verlängerung der Längserstreckung des Metallplättchens angeordnet sind und daher die Feldwirkungen der zwei oder mehr Magnetelemente sich ergänzen und verstärken.In a first advantageous embodiment, the at least one magnetic element can be arranged in extension of the longitudinal extent of the metal plate, in particular spaced from the metal plate. As a result, the magnetic field generated by the at least one magnetic element runs exactly in the direction of the longitudinal extent of the metal plate and can therefore the resonance of the metal plate maximum support when passing through a security gate. Thus, the detection properties of the merchandise security element are significantly improved or achieved in a small-sized magnetic element, the detection properties that are otherwise achievable only with more complex merchandise security elements. Also can be made by the size of the distance influencing the detection properties of the merchandise security element. Hiebei it is also possible to arrange more than one magnetic element, advantageously two magnetic elements relative to the metal plate, that the two or more magnetic elements are arranged in extension of the longitudinal extension of the metal plate and therefore complement and enhance the field effects of the two or more magnetic elements.

Von Vorteil hinsichtlich der Anwendung des Warensicherungselementes ist es, wenn das mindestens eine Magnetelement flach ausgebildet ist. Hierdurch kann dieses Magnetelement in ein ebenfalls flaches und damit raumsparendes Gehäuse integriert werden, wodurch die Anwendbarkeit an entsprechend sensiblen Waren gewährleistet wird. Eine Anordnung des an sich flach ausgebildeten Magnetelementes kann auch hochkant stehend bezogen auf die Ebene des Gehäuses des Warensicherungselementes erfolgen.An advantage with regard to the application of the merchandise security element, it is when the at least one magnetic element is flat. In this way, this magnetic element can be integrated into a likewise flat and thus space-saving housing, whereby the applicability to correspondingly sensitive goods is guaranteed. An arrangement of the in itself flat trained magnetic element can also be upright relative to the plane of the housing of the merchandise security element.

Denkbar ist es weiterhin, dass das mindestens eine Magnetelement permanentmagnetisch ausgebildet ist. Ein solches permanentmagnetisches Material kann beispielsweise ein Neodym-Magnetmaterial oder auch ein keramisches Magnetmaterial sein, das eine hohe Magnetfeldstärke bei nur geringen Abmessungen ermöglicht und daher das benötigte Volumen des Magnetelementes weiter reduziert. Die permanentmagnetische Ausgestaltung des Warensicherungselementes erlaubt es, Warensicherungselemente herzustellen, die nicht deaktiviert werden können und daher eine besonders hohe Sicherheit gegenüber Manipulationen aufweisen. Hierbei werden die Warensicherungselemente nach dem Kauf von der Ware entfernt und verbleiben dauerhaft innerhalb des Verkaufsgeschäftes und laufen dort mit unterschiedlichen Waren immer wieder um.It is also conceivable that the at least one magnetic element is permanently magnetic. Such a permanent magnetic material may for example be a neodymium magnetic material or a ceramic magnetic material which allows a high magnetic field strength with only small dimensions and therefore further reduces the required volume of the magnetic element. The permanent magnetic design of the merchandise security element makes it possible to produce merchandise security elements that can not be deactivated and therefore have a particularly high security against manipulation. Here, the merchandise security elements are removed after the purchase of the goods and remain permanently within the sales and run there with different goods over again.

Ebenfalls kann in einer anderen Ausgestaltung das mindestens eine Magnetelement deaktivierbar ausgebildet werden, wodurch z.B. als Etiketten ausgebildete Warensicherungselemente erzeugt werden können, die nach erfolgter Deaktivierung an der Ware verbleiben können und gleichwohl ohne Alarmierung aus dem Geschäft durch die Sicherheitsschleuse entfernt werden können. Hierbei ist es weiterhin von Vorteil, wenn zur Deaktivierung des Warensicherungselementes ein zusätzliches Metallteil vorgesehen wird, das sich entlang der Längserstreckung des Metallplättchens im wesentlichen über dessen ganze Länge parallel und benachbart zu dem Metallplättchen erstreckt und gegenläufig zu dem Magnetelement polbar ist. Durch ein Umpolen des Magnetfeldes innerhalb dieses zusätzlichen Metallteiles kann eine Veränderung des gesamten Wirkung des Warensicherungselementes derart erzeugt werden, dass mit gleichsinnig zu dem mindestens einen Magnetelement gepolten zusätzlichen Metallteil die Detektionswirkung gewährleistet ist, bei einer gegensinnigen Polung des durch einen starken externen Magneten in das Metallteil eingebrachten Wechselstrom-Magnetfeldes aber die Detektionswirkung durch Verstimmung der resultierenden Schwingungsfähigkeit des Metallplättchens nicht mehr gewährleistet ist. Damit kann aus einem an sich nicht deaktivierbaren Sicherungselement durch Hinzufügung des zusätzlichen Metallteiles ein deaktivierbares Sicherungselement erzeugt werden, ohne sonstige Änderungen vornehmen zu müssen.Likewise, in another embodiment, the at least one magnetic element can be designed to be deactivatable, as a result of which, for example, merchandise securing elements designed as labels can be generated, which can remain after the deactivation of the goods and can nevertheless be removed without alarm from the store through the security gate. In this case, it is also advantageous if an additional metal part is provided for deactivating the merchandise security element, which extends along the longitudinal extent of the metal plate substantially parallel over its entire length and adjacent to the metal plate and polbar in opposite directions to the magnetic element. By reversing the polarity of the magnetic field within this additional metal part, a change in the overall effect of the merchandise security element can be generated such that the detection effect is ensured in the same direction as the at least one magnetic element poled additional metal part, in an opposite polarity by a strong external magnet in the metal part introduced AC magnetic field but the detection effect is no longer guaranteed by detuning the resulting vibration ability of the metal plate. This can be generated from a non-deactivatable fuse element by adding the additional metal part a deactivatable fuse element without having to make any other changes.

Von Bedeutung für die Möglichkeiten der Sicherung auch von empfindlichen Waren ist es, wenn an dem Gehäuse des Warensicherungselementes ein Verschluss zur Festlegung des Warensicherungselementes an einer Ware ausgebildet ist, wobei dieser Verschluss in allen bekannten Arten von Verschlüssen aus dem Bereich der Warensicherungstechnik ausgebildet sein kann. Hierbei ist es in weiterer Ausgestaltung denkbar, dass der Verschluss an dem Gehäuse endseits gegenüberliegend zu dem in Längserstreckung des Metallplättchens angeordneten Magnetelement angeordnet ist und dadurch ggf. die Detektionseigenschaften des Warensicherungselementes durch seine Masse und sein Material weiter unterstützt.Of importance for the possibilities of securing even sensitive goods, it is when formed on the housing of the merchandise security element a closure for fixing the merchandise security element on a product, said closure may be formed in all known types of closures from the field of retail security. In this case, it is conceivable in a further embodiment that the closure on the housing end side opposite to the disposed in the longitudinal extent of the metal plate magnetic element is arranged and thereby possibly further supports the detection properties of the merchandise security element by its mass and its material.

Von besonderen Vorteil kann hierbei der Verschluss aus einem Kugelverschluss mit einer Anzahl von Klemmelementen gebildet sein, der sehr zuverlässig und sicher die Festlegung des Gehäuses des Warensicherungselementes an der Ware ermöglicht und für den darüber hinaus in vielen Verkaufsgeschäften auch entsprechende Öffner vorhanden sind.Of particular advantage in this case, the closure of a ball closure with a number of clamping elements may be formed, which allows very reliable and secure the determination of the housing of the merchandise security element on the goods and are also available in many sales outlets also corresponding opener.

Eine weitere Erhöhung der Manipulationssicherheit eines derartigen Verschlusses lässt sich erreichen, wenn der Verschluss mit Farbelementen aus mindestens einem zerbrechlichen Farbbehälter derart umgeben ist, dass eine unerlaubte Manipulation des Verschlusses erschwert ist. Hierdurch wird bei einer unerlaubten Manipulation der Farbbehälter mit hoher Sicherheit zerstört und die Farbe tritt aus und beeinträchtigt die Nutzbarkeit der so manipulierten Ware. Hierdurch wird in grundsätzlich bekannter Weise der Anreiz zur Manipulation derart gesicherter Waren reduziert.A further increase in the security against manipulation of such a closure can be achieved if the closure is surrounded with color elements of at least one fragile ink container such that an unauthorized manipulation of the closure is made more difficult. As a result, the ink container is destroyed with high security in an unauthorized manipulation and the color comes out and affects the usability of the so manipulated goods. As a result, the incentive to manipulate such secured goods is reduced in a basically known manner.

In anderer Ausgestaltung ist es auch denkbar, dass der Verschluss eine Schlaufe oder ein Seil oder ein Band aufweist, mit denen die Ware frei beweglich an dem Warensicherungselement festlegbar ist. Dies ist insbesondere für die Verwendung entsprechender Verschlüsse an sog. Henkelware von Vorteil, an der die Warensicherungselemente üblicherweise frei hängend befestigt werden. Eine Erhöhung der Manipulationssicherheit lässt sich bei derartigen Verschlüssen dadurch erreichen, dass die Schlaufe oder das Seil oder das Band des Verschlusses auf unzulässige Manipulationen überwacht wird, wie dies an sich grundsätzlich bekannt ist..In another embodiment, it is also conceivable that the closure has a loop or a rope or a band, with which the goods freely movable on the goods security element can be fixed. This is particularly advantageous for the use of corresponding closures on so-called Henkelware to which the merchandise security elements are usually attached freely suspended. An increase in the security against manipulation can be achieved in such closures in that the loop or the rope or the band of the closure is monitored for impermissible manipulation, as is basically known per se.

Eine Sicherstellung der Schwingungsfähigkeit des Metallplättchen bei Anregung in einer Sicherheitsschleuse lässt sich dadurch erreichen, dass das Metallplättchen in einer Aufnahme des Gehäuses derart aufgenommen ist, dass die freie Schwingungsfähigkeit des Metallplättchens nicht gehindert wird, wobei in weiterer Ausgestaltung in der Aufnahme des Gehäuses Einrichtungen zur Verhinderung des Klemmens, vorzugsweise in Form von Zylindern, Dreiecken, Bögen oder dgl. angeordnet sind.Ensuring the ability of the metal plate to vibrate when it is excited in a safety lock can be achieved by accommodating the metal plate in a receptacle of the housing such that the free vibration capability of the metal plate is not hindered, in a further embodiment in the receptacle of the housing the clamping, preferably in the form of cylinders, triangles, bows or the like. Are arranged.

Eine besonders bevorzugte Ausführungsform des erfindungsgemäßen Warensicherungselementes zeigt die Zeichnung.A particularly preferred embodiment of the inventive article securing element is shown in the drawing.

In der Figur 1 ist in einer Draufsicht ein erfindungsgemäßes Warensicherungselement 1 dargestellt, das in der Figur 2 in einer geschnittenen Seitenansicht noch einmal im Detail zu erkennen ist, wobei gleiche Sachnummern gleiche Bauteile bezeichnen.In the FIG. 1 is a plan view of an inventive merchandise security element 1 shown in the FIG. 2 can be seen again in detail in a sectional side view, wherein like part numbers designate the same components.

Das Warensicherungselement 1 besteht hierbei aus einem zweiteiligen Gehäuse 7 mit einem länglichen Abschnitt zur Aufnahme eines Metallplättchens 5 und mindestens einen Magnetelementes 6 sowie einem Aufnahmekopf 2 für einen üblichen Kugelverschluss 3, in den über einen Einsteckkanal 4 ein nicht dargestellter Dorn in grundsätzlich bekannter Weise zur Sicherung einer ebenfalls nicht dargestellten Ware eingesteckt und geklemmt werden kann. Die Ausgestaltung des Verschlusses 3 ist hier nicht von vorrangiger Bedeutung, wobei dieser Verschluss 3 in jeglicher Art wie bei Warensicherungselementen bekannt ausgestaltet werden kann und beispielsweise auch ein Umschlingungsseil oder dergleichen aufweisen kann.The merchandise security element 1 in this case consists of a two-part housing 7 with an elongated portion for receiving a metal plate 5 and at least one magnetic element 6 and a receiving head 2 for a conventional ball closure 3, in which a plug-in channel 4, not shown mandrel in a basically known manner for securing a product, also not shown, can be inserted and clamped. The design of the closure 3 is not of primary importance here, wherein this closure 3 can be configured in any way known as in consumer protection elements and, for example, may also have a looping rope or the like.

Angrenzend an diesen Aufnahmekopf 2 erstreckt sich der längliche Abschnitt des Gehäuses 7, der eine Aufnahmetasche 12 für ein schwingfähiges Metallplättchen 5 sowie davon über einen Abstandshalter 10 getrennt eine Aufnahmekammer 11 für ein Magnetelement 6 aufweist. Das Metallplättchen 5 ist länglich und flach ausgebildet, wobei die Längserstreckung des Metallplättchens 5 sich parallel zur Mittelachse des länglichen Abschnittes des Gehäuses 7 erstreckt. Das Metallplättchen 5 kann beispielsweise als ein Streifen Metglass ausgebildet sein und in der Aufnahmekammer 12 in grundsätzlich bekannter Weise aufgrund einer akustomagnetischen Anregung frei schwingen und eine Antwort an eine Sicherheitsschleuse eines akustomagnetischen Warensicherungssystems abgeben. Damit sich das Metallplättchen 5 auf jeden Fall frei schwingend innerhalb der Aufnahmekammer 12 bewegen kann, sind stirnseitig des Metallplättchens 5 Klemmverhinderer 8 in Form von Zylindern, Dreiecken, Bögen oder dgl. angeordnet, die nur eine punktuelle Anlagefläche für das Metallplättchen 5 aufweisen.Adjacent to this receiving head 2 extends the elongated portion of the housing 7, which has a receiving pocket 12 for a vibrating metal plate 5 and thereof via a spacer 10 separately, a receiving chamber 11 for a magnetic element 6. The metal plate 5 is elongated and flat, wherein the longitudinal extension of the metal plate 5 extends parallel to the central axis of the elongated portion of the housing 7. The metal plate 5 may be formed, for example, as a strip Metglass and vibrate freely in the receiving chamber 12 in a basically known manner due to a akustomagnetischen excitation and deliver a response to a security lock a akustomagnetischen goods security system. So that the metal plate 5 can move freely within the receiving chamber 12 in any case, are frontally of the metal plate 5 Klemmverhinderer 8 arranged in the form of cylinders, triangles, bows or the like., Which have only a punctual contact surface for the metal plate 5.

In Verlängerung der Längserstreckung 9 des Metallplättchens 5 ist ein Magnetelement 6 beispielsweise aus einem Neodym-Material in die Aufnahmekammer 11 eingelegt, das ein starkes Magnetfeld aufbaut, wobei dieses Magnetfeld durch die Anordnung des Magnetelementes 6 in Längserstreckung parallel zur Längserstreckung des Metallplättchens 5 die Schwingungsfähigkeit des Metallplättchens 5 an den Kopfenden verbessert. Hierdurch wird schon mit allein einem Magnetelement 6 bei der beschriebenen Anordnung relativ zu dem Metallplättchen 5 dafür gesorgt, dass die Schwingungsantwort des Metallplättchens 5 bei der Anregung in einer Sicherheitsschleuse groß genug ausfällt, um detektiert zu werden und damit ein Signal über einen versuchten Diebstahl abzugeben. Hierbei ist von Bedeutung, dass das Magnetelement 6 und das Metallplättchen 5 beabstandet voneinander durch einen Abstandshalter 10 in Form eines Teiles des Gehäuses 7 angeordnet sind, da durch die Größe des Abstandes des Abstandshalters 10 die Beeinflussung der Schwingungsfähigkeit des Metallplättchens 5 aufgrund der Magnetwirkung des Magnetelementes 6 möglich ist. Weiterhin ist beispielsweise bei Ausgestaltung des Verschlusses 3 als Kugelverschluss die dort angeordnete Metallmenge der Klemmelemente und der Feder des Kugelverschlusses 3 ebenfalls relevant für die Beeinflussung der Schwingungsfähigkeit des Metallplättchens 5, da das von dem Magnetelement 6 erzeugte Magnetfeld durch Streuung des Magneten (Trafowirkung) hiervon ebenfalls beeinflusst werden kann.In extension of the longitudinal extension 9 of the metal plate 5, a magnetic element 6 is inserted, for example, a neodymium material in the receiving chamber 11, which builds a strong magnetic field, this magnetic field by the arrangement of the magnetic element 6 in the longitudinal extent parallel to the longitudinal extent of the metal plate 5, the vibration of the Metal plate 5 at the head ends improved. As a result, even with only one magnetic element 6 in the described arrangement relative to the metal plate 5 ensured that the vibration response of the metal plate 5 fails when excited in a security lock enough to be detected and thus to give a signal about an attempted theft. It is important that the magnetic element 6 and the metal plate 5 are spaced from each other by a spacer 10 in the form of a part of the housing 7, since the size of the distance of the spacer 10 influencing the vibration of the metal plate 5 due to the magnetic effect of the magnetic element 6 is possible. Furthermore, for example, in embodiment of the closure 3 as a ball closure, the metal amount of the clamping elements and the spring of the ball closure 3 arranged there also relevant for influencing the vibration of the metal plate 5, since the magnetic field generated by the magnetic element 6 by scattering the magnet (transformer effect) thereof also can be influenced.

In der Figur 3 ist eine Variation des Warensicherungselementes 1 gemäß Figur 1 dargestellt, das als deaktivierbares Warensicherungselement 1 ausgebildet ist. Hierzu ist in einer weiteren Aufnahmekammer 14 parallel zur Aufnahmekammer des Metallplättchens 5 ein Metallteil 13 im wesentlichen über die ganze Länge des Metallplättchens 5 derart angeordnet, dass ein nicht dargestellter, externer starker Magnet in diesem Metallteil 13 ein Magnetfeld hervorrufen kann, wobei je nach Polung des Magnetfeldes des externen starken Magneten eine Beeinflussung des Magnetfeldes des Magnetelementes 6 und damit der Schwingungsfähigkeit des Metallplättchens 5 hervorgerufen werden kann. Dieses derart hervorgerufenen Magnetfeld muss dabei länger dauernd erhalten bleiben. Wirkt dieses Magnetfeld, das von dem externen starken Magneten in das Metallteil 13 eingekoppelt wird, gegen das Magnetfeld des Magnetelementes 6, so wird dieses resultierende Magnetfeld geschwächt und die Schwingungsantwort des Metallplättchens 5 fällt aus. Umgekehrt kann eine gleiche Polung der beiden Magnetfelder von Metallteil 13 und Magnetelement 6 eine Verbesserung der Schwingungsfähigkeit des Metallplättchens 5 hervorrufen. Damit kann in einem Verkaufsgeschäft ein derart gestaltetes Warensicherungselement 1 deaktiviert werden, indem das Magnetfeld des Metallteiles 13 entsprechend umgepolt wird und damit das Warensicherungselement entschärft werden.In the FIG. 3 is a variation of the merchandise security element 1 according to FIG. 1 shown, which is designed as a deactivatable merchandise security element 1. For this purpose, in a further receiving chamber 14 parallel to the receiving chamber of the metal plate 5, a metal part 13 substantially over the entire length of the metal plate 5 is arranged such that an unrepresented, external strong magnet in this metal part 13 can cause a magnetic field, depending on the polarity of Magnetic field of the external strong magnet influencing the magnetic field of the magnetic element 6 and thus the vibration ability of the metal plate 5 can be caused. This magnetic field caused in this way must be there stay longer lasting. If this magnetic field, which is coupled into the metal part 13 by the external strong magnet, acts against the magnetic field of the magnetic element 6, this resulting magnetic field is weakened and the vibration response of the metal plate 5 drops out. Conversely, an identical polarity of the two magnetic fields of metal part 13 and magnetic element 6 can cause an improvement in the vibration capability of the metal plate 5. This can be deactivated in a store such a designed merchandise security element 1 by the magnetic field of the metal part 13 is reversed accordingly and thus the merchandise security element be defused.

In der Figur 4 ist eine Abwandlung des Warensicherungselementes gemäß Figur 1 mit mehr als einem Magnetelement 6 dargestellt, wobei das hier zweite Magnetelement 6 in Verlängerung des Metallplättchens 5 derart angeordnet ist, dass sich die Magnetwirkungen der beiden Magnetelemente 6 ergänzen und zu einer Erhöhung des resultierenden Magnetfeldes führen. Hierfür liegt das zweite Magnetelement 6 in Verlängerung der Längserstreckung 9 des Metallplättchens 5, so dass die Magnetfeldlinien sich parallel zu denen des ersten Magnetelementes 6 in das Metallplättchen 5 einkoppeln und dieses aufgrund der gleichsinnigen Polung, d.h. der Südpol des einen Magnetelementes 6 wirkt über das Metallplättchen 5 mit dem Nordpol des anderen Magnetelementes 6 zusammen, der beiden Magnetelemente 6 verstärken. Damit ist eine verbesserte Detektionswirkung des Warensicherungselementes 1 erreichbar. Hierdurch kann die Länge des Metallplättchens 5 ebenfalls verringert werden, wodurch das Gehäuse 7 insgesamt wiederum verkleinert werden kann.In the FIG. 4 is a modification of the merchandise security element according to FIG. 1 shown with more than one magnetic element 6, wherein the second magnetic element 6 is arranged in extension of the metal plate 5 such that complement the magnetic effects of the two magnetic elements 6 and lead to an increase of the resulting magnetic field. For this purpose, the second magnetic element 6 is in extension of the longitudinal extension 9 of the metal plate 5, so that the magnetic field lines parallel to those of the first magnetic element 6 couple into the metal plate 5 and this due to the same direction polarity, ie the south pole of a magnetic element 6 acts on the metal plate 5 with the north pole of the other magnetic element 6 together, the two magnetic elements 6 reinforce. For an improved detection effect of the merchandise security element 1 can be achieved. In this way, the length of the metal plate 5 can also be reduced, whereby the housing 7 in turn can be reduced in total.
