Description

Die Erfindung betrifft ein Sicherheitsmaterial mit einem bahnartigen Gewirk und darin integrierten, isolierten, elektrisch leitfähigen Drähten.The invention relates to a security material with a web-like knitted fabric and integrated, insulated, electrically conductive wires.

Solche Materialien sind bekannt und werden zur Detektion von Einbrüchen, insbesondere in LKW- beziehungsweise Schiffscontainern, verwendet. Weitere Anwendungsmöglichkeiten sind zum Beispiel die Absicherung von wertvollen Produkten, Grundstücken, Zäunen, Lagerhallen, Museen usw. Hierbei kann das Sicherheitsmaterial so dünn gefertigt sein, dass ein Eindringling das Vorhandensein des Sicherheitsmaterials in der Regel nicht bemerkt oder es als Verpackungs- oder Abdeckmaterial ansieht. In einem solchen Fall kann ein lauter oder stiller Alarm in einer Überwachungsstation ausgelöst oder das Eindringen in einer Datenbank vermerkt werden.Such materials are known and used for the detection of burglary, especially in truck or shipping containers. Other possible applications include securing valuable products, land, fences, warehouses, museums, etc. In this case, the security material can be made so thin that an intruder usually does not notice the presence of the security material or regard it as packaging or covering material. In such a case, a loud or silent alarm can be triggered in a monitoring station or the intrusion into a database can be noted.

Falls das Sicherheitsmaterial an einer beliebigen Stelle durchtrennt wird, werden die darin integrierten haarfeinen Drähte ebenfalls verletzt, was eine angeschlossene Auswerteelektronik detektiert und als Eindringversuch interpretiert.If the security material is severed at any point, the hair-fine wires integrated therein are also injured, which detects a connected transmitter and interpreted as an intrusion attempt.

Derartige Sicherheitsmaterialien sind etwa aus der EP 0 725 881 B1 oder der US 7,352,284 B2 bekannt.Such safety materials are about from the EP 0 725 881 B1 or the US 7,352,284 B2 known.

Aufgabe der Erfindung ist es, ein Sicherheitsmaterial mit einem bahnartigen Gewirk und darin integrierten Drähten anzugeben, welches kostengünstig und auf einfache Weise herzustellen ist und gleichwohl Beschädigungen des Sicherheitsmaterials zuverlässig detektiert. The object of the invention is to provide a security material with a web-like knitted fabric and wires integrated therein, which is inexpensive and easy to manufacture and nevertheless reliably detects damage to the security material.

Diese Aufgabe wird durch ein Sicherheitsmaterial mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by a safety material having the features of claim 1. Preferred embodiments are specified in the dependent claims.

Das erfindungsgemäße Sicherheitsmaterial ist dadurch gekennzeichnet, dass ein erster Draht in Längsrichtung des bahnartigen Gewirks angeordnet ist und dass ein zweiter Draht mäanderförmig über die Breite des bahnartigen Gewirks in dessen Längsrichtung verläuft.The safety material according to the invention is characterized in that a first wire is arranged in the longitudinal direction of the web-like knitted fabric and that a second wire runs meander-shaped over the width of the web-like knitted fabric in its longitudinal direction.

Ein Grundgedanke der Erfindung kann in der Art und Weise, wie das Sicherheitsmaterial von Drähten durchzogen ist, gesehen werden. Hierbei durchläuft ein Draht das bahnartige Gewirk entlang der Breite schlaufenartig, so dass die vom Draht durchlaufene Fläche das Gewirk flächenmäßig abdeckt. Ein weiterer Draht wird an einem Ende des bahnartigen Gewirks mit dem anderen Draht verbunden und von dort entlang der Länge zurückgeführt. Durch Messung der Leitfähigkeit an den beiden verbleibenden freien Enden der Drähte kann somit ein Einbruch, bei dem ein Draht durchtrennt wird, auf einfache Weise detektiert werden. Eine solche Drahtanordnung lässt sich effektiv und wirtschaftlich in einem Gewirk herstellen.A basic idea of the invention can be seen in the way in which the security material is penetrated by wires. In this case, a wire runs through the web-like knitted fabric along the width like a loop, so that the surface passed through by the wire covers the area of the fabric. Another wire is connected to the other wire at one end of the web-like knit and then fed back along the length thereof. By measuring the conductivity at the two remaining free ends of the wires thus a break-in, in which a wire is cut, can be detected in a simple manner. Such a wire arrangement can be produced effectively and economically in a knitted fabric.

Erfindungsgemäß ist es besonders bevorzugt, dass der erste Draht an einem Rand des Gewirks angeordnet ist. Hierdurch wird vorteilhafterweise erreicht, dass elektrische Anschlüsse, seien es Anschlüsse an eine Messelektronik oder Anschlüsse an den zweiten Draht am Rand des Gewirks durchgeführt werden können. Dies hat den Vorteil, dass Anschlusskabel nicht umständlich mit Umwegen von der seitlichen Mitte des Gewirks zu den Anschlusspunkten geführt werden müssen, sondern direkt und platzsparend angeschlossen werden können.According to the invention, it is particularly preferred that the first wire is arranged at an edge of the knitted fabric. As a result, it is advantageously achieved that electrical connections, be it connections to a measuring electronics or connections to the second wire can be made at the edge of the knitted fabric. This has the advantage that connection cables do not have to be cumbersome with detours from the lateral center of the knitted fabric to the connection points, but can be connected directly and in a space-saving manner.

Eine weitere vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Drähte zum Schutz vor Beschädigung an zumindest einer Seitenfläche des Gewirks nicht über die Seitenfläche hervorragen. Durch diese Anordnung der Drähte, sei es in der Mitte des Gewirks oder aber an einer Vorder- oder Rückseite des Gewirks, wird vorteilhafterweise erreicht, dass die empfindlichen Drähte vor einer unbeabsichtigten Beschädigung, etwa bei der Installation des Sicherheitsmaterials, bewahrt werden.A further advantageous embodiment of the invention is characterized in that the wires do not project beyond the side surface for protection against damage to at least one side surface of the knitted fabric. By this arrangement of the wires, be it in the middle of the fabric or on a front or back side of the fabric, it is advantageously achieved that the sensitive wires are prevented from accidental damage, for example when installing the security material.

Weiterhin ist erfindungsgemäß bevorzugt, dass der Abstand zweier benachbarter Abschnitte des zweiten Drahts zueinander in der Größenordnung von Millimetern ist, insbesondere 2,3 mm beträgt. Der Abstand kann zwischen 1 mm und 20 mm betragen. Hierdurch wird erreicht, dass das Drahtnetz, welches sich in Längsrichtung und über die Breite des bahnartigen Gewirks, insbesondere abschnittsweise oder aber über die gesamte Breite des Gewirks, erstreckt, ein sehr dünnmaschiges Netz mit einem maximalen Abstand in der Größenordnung von Millimetern darstellt. Dadurch ist es für einen Einbrecher nahezu unmöglich, das Sicherheitsmaterial zu durchtrennen, ohne dass dabei auch der mäanderförmig verlaufende zweite Draht beschädigt wird.Furthermore, it is preferred according to the invention that the distance between two adjacent sections of the second wire is in the order of magnitude of millimeters, in particular 2.3 mm. The distance can be between 1 mm and 20 mm. This ensures that the wire mesh, which extends in the longitudinal direction and over the width of the web-like knitted fabric, in particular in sections or over the entire width of the knitted fabric, a very thin-meshed network with a maximum Represents a distance of the order of millimeters. This makes it almost impossible for a burglar to cut through the security material, without causing the meandering second wire is damaged.

In diesem Zusammenhang ist eine weitere besonders vorteilhafte Ausführungsform der Erfindung dadurch gekennzeichnet, dass die Drähte lackisolierte Metalldrähte, insbesondere Kupferdrähte sind, deren Durchmesser in der Größenordnung von einigen 50 Mikrometern, insbesondere 100 bis 150 µm liegen. Durch die Lackisolierung der Metalldrähte wird vorteilhafterweise erreicht, dass im Falle einer Berührung von elektrisch leitenden Gegenständen, z. B. Metallen oder Ähnlichem, keine elektrische Verbindung zwischen unterschiedlichen Drahtabschnitten hergestellt werden kann, was eine angeschlossene Messelektronik, die die Leitfähigkeit oder andere elektrische Eigenschaften der Metalldrähte misst, beeinträchtigen könnte. Kupfer eignet sich hierbei in vorzüglicher Weise, da Kupfer eine äußerst gute Leitfähigkeit besitzt. Durch den geringen Durchmesser der Drähte wird vorteilhafterweise erreicht, dass auch Eindringversuche mit geringem Kraftaufwand einen solchen Draht verletzen beziehungsweise durchtrennen, woraufhin der Eindringversuch detektiert wird.In this context, another particularly advantageous embodiment of the invention is characterized in that the wires are enamel-insulated metal wires, in particular copper wires, whose diameters are in the order of a few 50 micrometers, in particular 100 to 150 microns. By the paint insulation of the metal wires is advantageously achieved that in case of contact with electrically conductive objects, such. As metals or the like, no electrical connection between different wire sections can be made, which could interfere with a connected measuring electronics, which measures the conductivity or other electrical properties of the metal wires. Copper is excellently suited because copper has a very good conductivity. Due to the small diameter of the wires is advantageously achieved that even penetration attempts violate such a wire or cut with little effort, whereupon the penetration test is detected.

Erfindungsgemäß ist weiter vorgesehen, dass jeder Draht jeweils ein Verbindungselement zum elektrischen Verbinden der Drähte an eine Messelektronik aufweist. Hierdurch wird vorteilhafterweise erreicht, dass die Drähte in einfacher Weise - durch Verbinden der Verbindungselemente mit den entsprechenden Verbindungselementen einer Messelektronik oder Ähnlichem - an eine Analysevorrichtung angeschlossen werden können. Hierbei wird insbesondere daran gedacht, den Widerstand beziehungsweise die zeitliche Variation der Leitfähigkeit, insbesondere der beiden in Reihe geschalteten Drähte, zu analysieren. Hierdurch kann festgestellt werden, ob die beiden Drähte intakt sind oder bereits durchtrennt wurden. Durch Überwachung mit zeitlicher Variation kann auch ein eventuelles Überbrücken erkannt werden. Durch gepulste Messverfahren ist es auch möglich, zu erkennen, an welcher Stelle entlang der Länge des bahnartigen Gewirks eine Unterbrechung eines Drahts stattgefunden hat, wenn Leitungspaare, wie Zwillingslitzen oder Coaxialkabel, eingesetzt werden. Generell kann die Stelle erkannt werden, wenn entlang der Leitung eine konstante charakteristische Impedenz herrscht. Als ein Gewirk ist insbesondere ein Gebilde anzusehen, welches teilweise ein Gewebe und teilweise ein Gestrick ist.According to the invention it is further provided that each wire has in each case a connecting element for electrically connecting the wires to a measuring electronics. This advantageously achieves that the wires can be connected in a simple manner - by connecting the connecting elements with the corresponding connecting elements of a measuring electronics or the like - to an analysis device. In particular, it is thought to analyze the resistance or the temporal variation of the conductivity, in particular of the two wires connected in series. In this way it can be determined whether the two wires are intact or have already been severed. By monitoring with temporal variation also a possible bridging can be detected. By pulsed measuring methods it is also possible to detect at which point along the length of the web-like knitted fabric an interruption of a wire has taken place when pairs of lines, such as twin strands or coaxial cables, are used. In general, the position can be recognized if there is a constant characteristic impedance along the line. As a knitted fabric is in particular a structure to be considered, which is partially a fabric and partially a knit.

Hierbei ist weiterhin besonders bevorzugt, dass der erste Draht und der zweite Draht an ihren benachbarten Enden miteinander elektrisch verbunden sind und die beiden anderen Enden der Drähte zur Messung der Leitfähigkeit der verbundenen Drähte mit der Messelektronik verbunden sind. Durch diese Maßnahme wird unter Berücksichtigung, dass die beiden Drähte die ganze Fläche des bahnartigen Gewirks dichtmaschig abdecken, erreicht, dass die komplette Oberfläche des Sicherheitsmaterials überwacht werden kann. So kann jede Verletzung an einer beliebigen Stelle, die größer als eine Masche ist, detektiert werden. Somit ist eine sicherheitsmäßige Überwachung einer beliebigen Fläche, die durch ein bahnartiges Material abgedeckt werden kann, mit einem hohen Sicherheitsstandard möglich.In this case, it is further particularly preferred that the first wire and the second wire are electrically connected to one another at their adjacent ends, and the other two ends of the wires are connected to the measuring electronics for measuring the conductivity of the connected wires. By virtue of this measure, taking into account that the two wires cover the entire surface of the web-like knit tightly, it is achieved that the complete surface of the safety material can be monitored. Thus, any injury at any location greater than a mesh can be detected. Thus, a safety monitoring of any area that can be covered by a web-like material is possible with a high safety standard.

Eine weitere vorteilhafte Ausführungsform der Erfindung besteht darin, dass die elektrische Verbindung der Drähte mit der Messelektronik durch Löten, Schweißen oder mittels Schneidklemmen erfolgt. Durch diese Verbindetechniken wird vorteilhafterweise eine einfach zu realisierende, billige und zuverlässige elektrische Verbindung zwischen den Drähten erreicht.A further advantageous embodiment of the invention is that the electrical connection of the wires with the measuring electronics by soldering, welding or by means of cutting clamps. By means of these joining techniques, an easy-to-implement, inexpensive and reliable electrical connection between the wires is advantageously achieved.

Ferner ist hierbei erfindungsgemäß vorgesehen, dass die elektrische Verbindung der Drähte mit der Messelektronik über eine auf dem Gewirk befestigte Leiterplatte erfolgt. Hierbei ist es besonders bevorzugt, dass sich die Verbindung zwischen einem der Drähte und einem Verbindungspunkt auf der Leiterplatte direkt unter der Oberfläche der Leiterplatte befindet. Je nach Geometrie des ersten und zweiten Drahts ist es jedoch auch möglich, dass der Verbindungspunkt zwischen erstem oder zweitem Draht und dem Verbindungspunkt auf der Leiterplatte über einen zusätzlichen Draht verbunden wird. Von dem Verbindungspunkt auf der Leiterplatte führt eine Leiterbahn zu einem weiteren Anschluss, der mit der Messelektronik, zum Beispiel durch ein Kabel, verbunden ist. Besonders vorteilhaft ist hierbei, dass die Leiterplatte zur mechanischen Zugentlastung auch auf dem Gewirk befestigt, insbesondere mechanisch verzahnt oder geklebt, wird. Hierbei kann es abhängig vom Einsatzzweck vorgesehen sein, dass die Leiterplatte flexibel oder steif ausgebildet ist.Furthermore, it is provided according to the invention that the electrical connection of the wires to the measuring electronics takes place via a printed circuit board fastened to the fabric. It is particularly preferred that the connection between one of the wires and a connection point on the circuit board is located directly under the surface of the circuit board. However, depending on the geometry of the first and second wires, it is also possible for the connection point between the first or second wire and the connection point on the circuit board to be connected via an additional wire. From the connection point on the circuit board leads a conductor to another terminal, which is connected to the measuring electronics, for example by a cable. It is particularly advantageous that the circuit board for mechanical strain relief also attached to the fabric, in particular mechanically interlocked or glued, is. It may be provided depending on the purpose that the circuit board is flexible or stiff.

Eine weitere vorteilhafte Ausführungsform der Erfindung besteht darin, dass die Mäander des zweiten Drahts in Form von Schlaufen seitlich über das bahnartige Gewirk herausragen. Diese Form der Drahtschlaufen ist in der Praxis sehr einfach herzustellen.A further advantageous embodiment of the invention is that the meanders of the second wire in the form of loops protrude laterally beyond the web-like knit. This form of wire loops is very easy to make in practice.

In diesem Zusammenhang ist erfindungsgemäß ferner vorgesehen, dass die seitlichen Gewirkkanten und die Drahtschlaufen zum Schutz der Drahtschlaufen in ein Nahtband, insbesondere mit einer Dicke von 250 µm, eingebettet sind. Da die seitlich aus dem Gewirk herausragende Schlaufenform der Drähte einfach verletzt werden kann, ist ein Schutz der Drähte notwendig. Hierzu wird ein Nahtband, insbesondere ein sogenanntes heiß schmelzendes (hotmelt) Seamtape verwendet. Das längliche Band wird der Länge nach um eine Kante des Gewirks und somit auch entlang der Drahtschlaufen gelegt, dann zu den beiden Seitenflächen des Gewirks hin umgeklappt und mit der klebenden Seite an den jeweiligen Seitenflächen des Gewirks festgedrückt. Bevorzugt wird das Band ohne Umklappen in das Gewirk mit Hitze eingepresst. Möglich ist auch die Verwendung eines einfachen Klebebandes.In this context, the invention further provides that the lateral knitted edges and the wire loops are embedded to protect the wire loops in a seam tape, in particular with a thickness of 250 microns. Since the loop shape of the wires projecting laterally out of the knitted fabric can easily be damaged, protection of the wires is necessary. For this purpose, a seam tape, in particular a so-called hot-melted (hotmelt) seam tape is used. The elongated band is placed lengthwise around an edge of the knit and thus along the wire loops, then folded down to the two side surfaces of the knit and squeezed with the adhesive side against the respective side surfaces of the knit. Preferably, the tape is pressed without folding into the knit with heat. It is also possible to use a simple adhesive tape.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Sicherheitsmaterials ist dadurch gekennzeichnet, dass das Gewirk zur Durchführung von Leitungen, Durchführungen, Verbindungs- und Befestigungselementen oder Ähnlichem eine Öffnung aufweist, ohne dass an der Stelle der Öffnung Drahtverbindungen unterbrochen werden. Erfindungsgemäß sind hier zwei Möglichkeiten vorgesehen. Bei der ersten Möglichkeit wird auf dem Gewirk über der Öffnung eine Leiterplatte befestigt, welche größer als die Öffnung ist und deren Leiterbahnen die jeweiligen Enden jeder Drahtverbindung miteinander verbinden. Die Leiterplatte muss ebenso über eine Öffnung verfügen, die mindestens so groß ist, dass die verwendete Durchführung hindurchpasst. Hierdurch wird vorteilhafterweise erreicht, dass man durch das Sicherheitsmaterial Durchführungen, wie z.B. Leitungen, Verbindungen und Befestigungselemente durch das Sicherheitsmaterial hindurchführen kann, ohne das engmaschige Drahtnetz dabei zu verletzen. Eine weitere Möglichkeit, eine Öffnung in dem Sicherheitsmaterial anzubringen, besteht darin, einen schmalen Schlitz entlang der Breite des Gewirks entlang der Drahtabschnitte des zweiten Drahts in das Gewirk einzuarbeiten. Falls die beiden Schlitzenden im Gewirk aufeinander zu bewegt werden, entsteht eine schlitzförmige Öffnung im Gewirk, durch die Durchführungen gesteckt werden können. Ferner kann das Gewirk in der Umgebung des Schlitzes durch ein Nahtband, welches an der Schlitzöffnung ebenfalls aufgeschnitten ist, verstärkt werden.A further advantageous embodiment of the security material according to the invention is characterized in that the knitted fabric for the passage of lines, feedthroughs, connecting and fastening elements or the like has an opening, without being interrupted at the location of the opening wire connections. According to the invention, two options are provided here. In the first possibility, a printed circuit board which is larger than the opening and whose interconnects connect the respective ends of each wire connection is fastened to the knitted fabric via the opening. The circuit board must also have an opening that is at least large enough to fit through the feedthrough used. This advantageously achieves that through the security material passages, such as e.g. Lines, connections and fasteners can pass through the security material, without damaging the close-meshed wire mesh thereby. Another way to provide an opening in the security material is to incorporate a narrow slot along the width of the fabric along the wire sections of the second wire into the knit. If the two slot ends in the knitted fabric are moved toward each other, a slot-shaped opening is formed in the knitted fabric through which feedthroughs can be inserted. Furthermore, the knit in the vicinity of the slot can be reinforced by a seam band, which is also cut open at the slot opening.

Schließlich ist es erfindungsgemäß bevorzugt, dass das Gewirk in regelmäßigen Abständen in Längsrichtung, insbesondere alle 25 mm, eine Markierlinie in Form eines fehlenden, entlang der Breite verlaufenden Fadens aufweist. Da das Material bahnartig vorliegt, ist es somit in einfacher Weise möglich, bestimmte Längen des Materials abzumessen und abzuschneiden. Da die Markierlinie in Form eines fehlenden Fadens in dem Material verläuft, ist das Material an dieser Stelle ebenfalls leicht zu durchtrennen.Finally, it is inventively preferred that the knitted fabric at regular intervals in the longitudinal direction, in particular every 25 mm, has a marking line in the form of a missing, running along the width of the thread. Because the material is like a web is present, it is thus possible in a simple manner to gauge certain lengths of the material and cut off. Since the marking line runs in the form of a missing thread in the material, the material at this point is also easy to cut.

Fig. 1 zeigt ein erfindungsgemäßes Sicherheitsmaterial 10 bestehend aus einem bahnartigen Gewirk 12 und darin integrierten, isolierten, elektrisch leitfähigen Drähten 14, 16. Ein erster Draht 14 ist am Rande des Gewirks 12 in Längsrichtung 18 des bahnartigen Gewirks 12 angeordnet. Ein zweiter Draht 16 verläuft über die ganze Breite B des bahnartigen Gewirks 12 mäanderförmig entlang der Längsrichtung 18 des Gewirks 12 und kreuzt so den ersten Draht 14 mehrfach. Die benachbarten parallelen Abschnitte des zweiten Drahts 16 haben jeweils einen Abstand D voneinander. In den Biegungen des mäanderförmigen Verlaufs des zweiten Drahtes 16 entstehen Drahtschlaufen 28, die in Richtung der Breite B des bahnartigen Gewirks 12 über die Kanten des Gewirks 12 hinausragen. Im Gewirk 12 befinden sich ebenfalls in regelmäßigen Abständen in Längsrichtung Markierlinien 30 in Form eines fehlenden über die gesamte Breite des Gewirks 12 verlaufenden Fadens. Das Gewirk 12 selbst kann auf Monofil- oder Multifilfäden, insbesondere aus einem Kunststoff, aufgebaut sein. In Längsrichtung 18 können die Fäden wie der erste Draht 14 als Schussfäden angeordnet sein, während die in Breitenrichtung verlaufenden Fäden und der zweite Draht 16 als Kettfäden angesehen werden können. Fig. 1 shows a security material according to the invention 10 consisting of a web-like knitted fabric 12 and integrated, insulated, electrically conductive wires 14, 16. A first wire 14 is disposed at the edge of the fabric 12 in the longitudinal direction 18 of the web-like knitted fabric 12. A second wire 16 extends over the entire width B of the web-like knitted fabric 12 meandering along the longitudinal direction 18 of the knitted fabric 12 and thus crosses the first wire 14 several times. The adjacent parallel portions of the second wire 16 each have a distance D from each other. In the bends of the meandering course of the second wire 16 arise wire loops 28 which protrude in the direction of the width B of the web-like knitted fabric 12 over the edges of the fabric 12. In the knit 12 are also at regular intervals in the longitudinal direction marking lines 30 in the form of a missing over the entire width of the knit 12 extending yarn. The knit 12 itself may be constructed on monofilament or multifilament yarns, in particular of a plastic. In the longitudinal direction 18, the threads, like the first wire 14, can be arranged as weft threads, while the threads running in the width direction and the second wire 16 can be regarded as warp threads.

Fig. 2 verdeutlicht die elektrischen Verbindungen 36 eines erfindungsgemäßen Sicherheitsmaterials 10 aus Fig. 1. Nachdem das bahnartige Sicherheitsmaterial 10 abgelängt wurde, kann am linken und rechten Ende des Gewirks 12 ein Verlauf des ersten Drahts 14 und zweiten Drahts 16 wie in Fig. 2 abgebildet entstehen. Der erste Draht 14 und der zweite Draht 16 werden im vorliegenden Ausführungsbeispiel am linken Ende durch zwei elektrische Verbindungen 36 miteinander elektrisch leitend verbunden. Am rechten Ende werden die beiden Drähte 14, 16 jeweils über ein Kabel mit einer Messelektronik 20 verbunden. Durch diese Anordnung werden die beiden Drähte 14, 16 sozusagen in Reihe geschaltet und beide Enden dieser Reihenschaltung mit der Messelektronik 20 verbunden. Die Messelektronik 20 misst die elektrische Leitfähigkeit der Reihenschaltung des ersten Drahts 14 und des zweiten Drahts 16 sowie der dazwischen geschalteten Kabel 42. Aufgrund der Anordnung der elektrischen Verbindungen 36 in Fig. 2 ist es nicht möglich die Abschnitte der Drähte 14, 16 links der elektrischen Verbindung 36 auf der linken Seite von Fig. 2 und die Abschnitte der Drähte 14, 16 rechts der elektrischen Verbindung 36 auf der rechten Seite von Fig. 2 zu messen. Um eine möglichst umfassende Einbruchsdetektion zu gewährleisten, ist es somit vorteilhaft, die elektrischen Verbindungen 36 zwischen den Drähten 14, 16 an den äußeren Enden des Gewirks 12 anzubringen. Das Gewirk 12 kann bei der Installation am Rand umgeklappt werden, so dass die Überwachung bis zum Rand gegeben ist. Fig. 2 illustrates the electrical connections 36 of a security material 10 according to the invention Fig. 1 , After the sheet-like security material 10 has been cut to length, at the left and right ends of the fabric 12, a course of the first wire 14 and second wire 16 as in Fig. 2 pictured arise. The first wire 14 and the second wire 16 are connected in the present embodiment at the left end by two electrical connections 36 with each other electrically conductive. At the right end of the two wires 14, 16 are each connected via a cable with a measuring electronics 20. As a result of this arrangement, the two wires 14, 16 are connected in series, as it were, and both ends of this series connection are connected to the measuring electronics 20. The measuring electronics 20 measures the electrical conductivity of the series connection of the first wire 14 and the second wire 16 and the intermediate cable 42. Due to the arrangement of the electrical connections 36 in Fig. 2 it is not possible the portions of the wires 14, 16 left of the electrical connection 36 on the left side of Fig. 2 and the portions of the wires 14, 16 to the right of the electrical connection 36 on the right side of FIG Fig. 2 to eat. In order to ensure as extensive as possible burglar detection, it is thus advantageous to attach the electrical connections 36 between the wires 14, 16 at the outer ends of the knitted fabric 12. The fabric 12 can be folded over during installation at the edge, so that the monitoring is given to the edge.

Fig. 3 verdeutlicht die elektrische Kontaktierung der Drähte 14, 16 des erfindungsgemäßen Sicherheitsmaterials 10 aus Fig. 2. In der Ebene des Gewirks 12 ist hierbei ein Abschnitt des Gewirks 12 in der Nähe der in Fig. 2 rechts abgebildeten elektrischen Verbindung 36 mit einer Leiterplatte 26 zu sehen, die auf dem Gewirk 12 befestigt ist. Die Leiterplatte 26 wird auf einer Seitenfläche des Gewirks 12 so angebracht, dass die Leiterplatte 26 über einem oder zwei Teilabschnitten des zweiten Drahts 16 liegt. Hierdurch können die beiden elektrischen Verbindungen 36, die in Fig. 2 auf der rechten Seite abgebildet sind, direkt mit der Leiterplatte 26, zum Beispiel durch Löten, verbunden werden. Von diesen elektrischen Verbindungen 36 ausgehend werden Kabel 42 zur Messelektronik 20 geführt. Alternativ können alle Drähte und elektrischen Verbindungen an einer Seitenfläche des Gewirks 12 angeordnet sein. Fig. 3 illustrates the electrical contacting of the wires 14, 16 of the security material 10 according to the invention Fig. 2 , In the plane of the knitted fabric 12, a portion of the knit fabric 12 is in the vicinity of the in Fig. 2 Right seen to see electrical connection 36 with a circuit board 26 which is mounted on the fabric 12. The circuit board 26 is mounted on a side surface of the fabric 12 so that the circuit board 26 overlies one or two sections of the second wire 16. This allows the two electrical connections 36, which in Fig. 2 on the right side are directly connected to the printed circuit board 26, for example by soldering. Starting from these electrical connections 36, cables 42 are led to the measuring electronics 20. Alternatively, all wires and electrical connections may be disposed on a side surface of the fabric 12.

Fig. 4 und Fig. 5 beschreiben zwei Ausführungsformen eines erfindungsgemäßen Sicherheitsmaterials 10, bei denen sich im Gewirk 12 Öffnungen 22, 24 befinden. Fig. 4 zeigt eine Aufsicht eines solchen Sicherheitsmaterials 10, bei dem in das Gewirk 12 ein Loch geschnitten wurde und die durchtrennten Drahtabschnitte durch entsprechende Leiterbahnen 38 einer Leiterplatte 26 ersetzt wurden. Dazu wird auf die im Gewirk 12 befindliche Öffnung 22 eine Leiterplatte 26 befestigt, welche größer als die Öffnung 22 ist. Durch die Öffnung 22 kann zum Beispiel ein Bolzen 32 durch das Gewirk 12 gesteckt werden. Um die Öffnung 22 herum befinden sich oben und unten mehrere Drahtenden 40, die bei der Erstellung der Öffnung 22 entstanden sind. Die Leiterbahnen 38 der Leiterplatte 26 müssen demnach so positioniert sein, dass sie die jeweiligen Drahtenden 40, welche zuvor durch Drahtabschnitte miteinander verbunden waren, unter Umgehung der Öffnung 22 durch jeweils eine elektrische Verbindung 36 miteinander verbinden. 4 and FIG. 5 describe two embodiments of a security material 10 according to the invention, in which there are 12 openings 22, 24 in the knitted fabric. Fig. 4 shows a plan view of such a security material 10, in which the knitted fabric 12 a Hole was cut and the severed wire sections were replaced by corresponding tracks 38 of a circuit board 26. For this purpose, a circuit board 26 which is larger than the opening 22 is fastened to the opening 12 located in the knitted fabric 12. Through the opening 22, for example, a bolt 32 can be inserted through the knit 12. Around the opening 22 are located above and below a plurality of wire ends 40, which are formed when creating the opening 22. The conductor tracks 38 of the printed circuit board 26 must therefore be positioned so that they connect the respective wire ends 40, which were previously connected to each other by wire sections, bypassing the opening 22 by an electrical connection 36 with each other.

Fig. 5 stellt eine weitere Möglichkeit dar, eine Öffnung in das Sicherheitsmaterial 10 einzuarbeiten. Hierzu wird das Gewirk 12 an der Stelle, an der das Gewirk 12 aufgeschnitten werden soll, zuerst mittels eine Nahtbandes 34 verstärkt und sodann entlang zweier paralleler Drahtabschnitte des zweiten Drahts 16 aufgeschnitten. Falls die beiden Enden des Schnitts gegeneinander geschoben werden, entsteht eine schlitzförmige Öffnung 24, durch die zum Beispiel ein Bolzen 32 geschoben werden kann. Fig. 5 represents another way to incorporate an opening in the security material 10. For this purpose, the knitted fabric 12 at the point at which the knitted fabric 12 is to be cut open, first reinforced by means of a seam tape 34 and then cut along two parallel wire sections of the second wire 16. If the two ends of the cut are pushed against each other, a slot-shaped opening 24 is formed, through which, for example, a bolt 32 can be pushed.
