Vorrichtungen zum Zwecke der elektronischen Warensicherung wie die, z.B die aus dem Dokument De 19544852 bekannt sind mittlerweile in Kaufhäusern und Lagern weit verbreitet. Durch die Installation derartiger Vorrichtungen lassen sich durch Diebstahl bedingte Inventurverluste entscheidend vermindern. Üblicherweise sind die elektronischen Überwachungsvorrichtungen im Ein- bzw. Ausgangsbereich von Kaufhäusern und Lagern zu finden, um das unerlaubte Entfernen der entsprechend gesicherter Artikel aus dem Verkaufs- oder Lagerbereich anzuzeigen.Devices for the purpose of electronic article surveillance such as those which are known from document De 19544852 are now known widespread in department stores and warehouses. By installing such Devices can be crucial due to theft-related inventory losses Reduce. Usually the electronic monitoring devices in the entrance and exit area of department stores and warehouses find out the unauthorized removal of the appropriately secured item the sales or warehouse area.

Die im Stand der Technik beschriebenen Überwachunsvorrichtungen zeigen die unterschiedlichsten Designs. So ist beispielsweise aus der EP 0 668 626 A1 eine Antennenvorrichtung bekannt geworden, die aus einem Gehäuse zur Aufnahme der Sende- und Empfangsantennen und einem Rahmen besteht, der sich im wesentlichen entlang der äußeren Randbereiche des Gehäuses erstreckt. Insbesondere ist bei der bekannten Vorrichtung vorgesehen, daß das an der oberen Kante des Gehäuses vorgesehene Rahmenteil abnehmbar ist, so daß die Antennenanordnung durch die freigegebene Öffnung aus dem Gehäuse herausgenommen bzw. in das Gehäuse hineingebracht werden kann. The monitoring devices described in the prior art show the different designs. For example, EP 0 668 626 A1 Antenna device has become known, consisting of a housing for receiving the transmit and receive antennas and a frame that is in the extends substantially along the outer edge regions of the housing. In particular, it is provided in the known device that the provided upper edge of the housing frame part is removable so that the Antenna arrangement removed through the released opening from the housing or can be brought into the housing.

Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstige Vorrichtung zur Überwachung von elektronisch gesicherten Artikeln vorzuschlagen.The invention is based, an inexpensive device for Propose monitoring of electronically secured items.

Die Aufgabe wird dadurch gelöst, daß die Vorrichtung aus einzelnen Materialschichten aufgebaut ist, wobei jede der Materialschichten für sich genommen biegsam und von geringer Festigkeit ist, während die Materialschichten in Kombination sich durch eine hohe Biegesteifigkeit und Festigkeit auszeichnen. Erfindungsgemäß wird der Effekt ausgenutzt, daß durch ein Zusammenfügen einzelner Schichten relativ geringer Stabilität letztendlich eine Festigkeit und Biegesteifigkeit erreicht wird, die die Summe der Festigkeiten und Biegesteifigkeiten der Einzelschichten um ein Vielfaches übersteigt. Da die gestellten Anforderungen an die einzelnen Materialschichten - insbesondere sei hier deren Stabilität erwähnt - relativ gering sein können, läßt sich die erfindungsgemäße Vorrichtung sehr kostengünstig fertigen.The object is achieved in that the device consists of individual Material layers is built up, with each of the material layers for themselves taken pliable and of low strength while the layers of material in combination through high bending stiffness and strength distinguished. According to the invention, the effect is exploited that by Joining individual layers of relatively low stability ultimately one Strength and bending stiffness is achieved, which is the sum of the strengths and Bending stiffness of the individual layers exceeds many times. Since the requirements placed on the individual layers of material - in particular their stability mentioned here - can be relatively low, the Manufacture device according to the invention very inexpensively.

Gemäß einer vorteilhaften Weiterbildung setzt sich die erfindungsgemäße Vorrichtung aus folgenden Schichten zusammen: einer ersten Seitenwand aus einem biegsamen Material, einer Füllschicht aus einem flexiblen Material, einer Trägerschicht aus einem flexiblem Material, deren Oberfläche derart strukturiert ist, daß sie zur Aufnahme der Sendespulen und/oder Empfangsspulen geeignet ist, und einer zweiten Seitenwand aus einem biegsamen Material.According to an advantageous further development, the invention is set Device composed of the following layers: a first side wall a flexible material, a filling layer made of a flexible material, a carrier layer made of a flexible material, the surface of which is such is structured so that it receives the transmitter coils and / or receiver coils is suitable, and a second side wall made of a flexible material.

Um zu verhindern, daß Störsignale, die von außerhalb der Überwachungszone kommen, die Detektionsrate innerhalb der Überwachungszone herabsetzen, ist gemäß einer ersten Alternative die erste Seitenwand aus einem Material gefertigt ist, das elektromagnetische Strahlung abschirmt. Als geeignete Materialien kommen alle leitfähigen Materialien in Frage. Gemäß einer bevorzugten Ausführungsform besteht die Seitenwand aus Aluminium. Es hat sich herausgestellt, daß eine Dicke der Aluminiumschicht im Millimeterbereich völlig ausreichend ist.To prevent interference from outside the surveillance zone coming, reduce the detection rate within the surveillance zone According to a first alternative, the first side wall is made of one material that shields electromagnetic radiation. As suitable materials all conductive materials can be used. According to a preferred Embodiment, the side wall is made of aluminum. It turned out that a thickness of the aluminum layer completely in the millimeter range is sufficient.

Eine Variante zu der zuvorbeschriebenen Ausführungsform sieht vor, daß zwischen erster Seitenwand und Füllschicht auf der der Überwachungszone abgewandten Seite eine separate, biegsame Abschirmschicht vorgesehen ist. Wiederum ist diese Abschirmschicht aus Aluminium gefertigt, welches eine Dicke von wenigen Zehntel Millimetern aufweisen kann. A variant of the previously described embodiment provides that between the first side wall and filler layer on that of the surveillance zone facing away from a separate, flexible shielding layer is provided. Again, this shielding layer is made of aluminum, which has a thickness of a few tenths of a millimeter.

Gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß die einzelnen Schichten zumindest punktuell fest miteinander verbunden sind. Im einfachsten Fall sind die Schichten miteinander verklebt.According to an advantageous development of the device according to the invention provided that the individual layers at least at certain points firmly together are connected. In the simplest case, the layers are glued together.

Es hat sich als kostengünstig und zur Erreichung der erforderlichen Stabilität der erfindungsemäßen Vorrichtung als völlig ausreichend herausgestellt, wenn die Füllschicht aus Styropor oder aus Füllschaum gefertigt ist. Bei der Verwendung von Styropor hat dieser eine Form, die zur entsprechenden Seite der Trägerschicht komplementär ausgebildet ist. Wird Füllschaum verwendet, so wird dieser direkt auf die entsprechende Seite der Trägerschicht aufgebracht.It has proven to be inexpensive and to achieve the required stability Device according to the invention turned out to be completely sufficient if the Filling layer made of styrofoam or of filling foam. When using Styrofoam has a shape that leads to the corresponding side of the carrier layer is complementary. If filling foam is used, it becomes applied directly to the corresponding side of the carrier layer.

Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung handelt es sich bei der Trägerschicht um ein zusammengepreßtes Glasfasermaterial. Selbstverständlich wäre auch die Verwendung eines Spritzgußteils möglich.According to an advantageous embodiment of the device according to the invention the carrier layer is a compressed glass fiber material. Of course, the use of an injection molded part would also be possible.

Um die Anforderungen an die üblichen Sicherheitsstandards in öffentlichen Bereichen zu gewährleisten, sind die Seitenwände der erfindungsgemäßen Vorrichtung aus einem schwerentflammbaren Material gefertigt.To meet the requirements of the usual security standards in public To ensure areas are the side walls of the invention Device made of a flame retardant material.

Desweiteren schlägt eine günstige Weiterbildung der erfindungsgemäßen Vorrichtung vor, daß Seitenprofile und zumindest ein Abdeckprofil vorgesehen sind, die die Seitenbereiche der Materialschichten umschließen.Furthermore, a favorable further development of the invention suggests Device before that side profiles and at least one cover profile is provided are that enclose the side areas of the material layers.

Die Erfindung wird anhand der nachfolgenden Figuren näher erläutert. Es zeigt:

  • Fig. 1: eine Draufsicht auf eine Ausgestaltung der erfindungsgemäßen Vorrichtung,
  • Fig. 2: eine Draufsicht auf die Trägerschicht mit montierten Empfangsspulen,
  • Fig. 3: eine Draufsicht auf die Trägerschicht mit montierter Sendespule und
  • Fig. 4: einen Querschnitt durch die erfindungsgemäße Vorrichtung gemäß der Kennzeichnung IV-IV in Fig. 3.
    • The invention is explained in more detail with reference to the following figures. It shows:
  • 1: a plan view of an embodiment of the device according to the invention,
  • 2: a top view of the carrier layer with mounted receiving coils,
  • 3 shows a plan view of the carrier layer with the transmitter coil and
  • 4 shows a cross section through the device according to the invention according to the identification IV-IV in FIG. 3.

    • Fig. 1 zeigt eine Draufsicht auf eine Ausgestaltung der erfindungsgemäßen Vorrichtung 1. Die Vorrichtung 1 wird auf ihrer Vorderseite und ihrer Rückseite jeweils von einer Seitenwand 2a, 2b begrenzt. Wie bereits an vorhergehender Stelle erwähnt, kann die der Überwachungszone abgewandte Seitenwand gleichzeitig als Abschirmschicht 12 ausgebildet sein. Die Seitenwände sind, um die Sicherheitsbestimmungen in öffentlichen Einrichtungen zu erfüllen, aus einem schwerentflammbaren Material gefertigt.Fig. 1 shows a plan view of an embodiment of the invention Device 1. The device 1 is on its front and back each delimited by a side wall 2a, 2b. As in the previous one Point mentioned, the side wall facing away from the surveillance zone be simultaneously formed as a shielding layer 12. The side walls are around meet the security requirements in public facilities from one flame retardant material.

    Zwischen den beiden Seitenwänden 2a, 2b sind - wie in Fig. 4 dargestellt - zwei weitere Schichten angeordnet: eine Trägerschicht 7 mit einer strukturierten Oberfläche zur Aufnahme der Empfangsspulen (8) und/oder der Sendespulen (9) und eine Füllschicht 10. Während die Trägerschicht 7 vorzugsweise aus gepreßtem Glasfasermaterial besteht, handelt es sich bei der Füllschicht 10 entweder um Styropor oder um einen Füllschaum. Die einzelnen Schichten der erfindungsgemäßen Vorrichtung sind zumindest punktuell miteinander verbunden. Im einfachsten Fall sind sie miteinander verklebt.Between the two side walls 2a, 2b, as shown in FIG. 4, there are two further layers arranged: a carrier layer 7 with a structured Surface for receiving the receiving coils (8) and / or the transmitting coils (9) and a filler layer 10. While the backing layer 7 is preferably made of pressed glass fiber material, it is the filling layer 10 either around styrofoam or around a filling foam. The individual layers of the Device according to the invention are connected to one another at least at certain points. In the simplest case, they are glued together.

    Um der Überwachungsvorrichtung 1 ein ansprechendes Design zu verleihen, sind die Seitenbereiche und die oberen Bereiche der Materialschichten mit Seitenprofilen 3 und einem Abdeckprofil 4 abgeschlossen. Im Bereich des Abdeckprofils befindet sich eine Alarmvorrichtung, die üblicherweise derart ausgebildet ist, daß sie das Erkennen eines elektronisch gesicherten Artikels in der Überwachungszone akustisch und optisch anzeigt.In order to give the monitoring device 1 an attractive design the side areas and the upper areas of the material layers with side profiles 3 and a cover profile 4 completed. In the area of the cover profile there is an alarm device, which is usually designed such that the detection of an electronically secured article in the surveillance zone acoustically and optically.

    Die Vorrichtung 1 wird mittels der seitlich angebrachten Befestigungselemente 6 am Boden festgemacht, das heißt, ein flächiges Element relativ großer Höhe steht frei im Ausgangs- oder Kassenbereich eines Kaufhauses und ist weit unterhalb seines Schwerpunktes befestigt. Bedenkt man weiterhin, daß sich Vorrichtung 1 in einem Bereich befindet, in dem reger Publikumsverkehr herrscht, wobei die Kunden üblicherweise noch mit Einkaufswagen unterwegs sind, so wird deutlich, welchen hohen Anforderungen an die Stabilität die Vorrichtung genügen muß. Während bei allen bisher bekannten Vorrichtungen die erforderliche Stabilität nur durch Verwendung entsprechend stabiler und teuerer Materialien erreicht wurde, schafft es die erfindungsgemäße Vorrichtung überraschenderweise, durch die Kombination biegsamer bzw. flexibler und kostengünstiger Materialschichten einen vergleichbaren Effekt zu erzielen. The device 1 is attached by means of the laterally attached fastening elements 6 moored to the ground, that is, a flat element of relatively great height free in the exit or checkout area of a department store and is far below attached to his focus.
