Definitions
- the invention relates to a combination of a lock cylinder with a magnetically activated locking mechanism and a device for detecting a manipulation attempt with a strong external magnetic field.
- Lock cylinder with a magnetically activated locking mechanism are for example from the DE 199 01 838 A1 known.
- a locking bolt is slidably disposed in a bore of the housing and is biased by a spring element in the direction of the core.
- the core has pockets for receiving the locking bolt.
- an armature connected to the locking bolt is pressed against an electromagnet of the electromagnetically activatable locking mechanism.
- the electromagnet is energized and holds the armature.
- the locking bar is held within the housing, and the core can be rotated relative to the housing.
- the magnetically activatable locking mechanism usually has high permeability, ferromagnetic materials with low coercive force. However, such a locking mechanism is susceptible to strong magnetic interference fields, which could be used for example in a manipulation attempt with a strong magnet.
- the invention is therefore based on the problem to provide a combination of a lock cylinder with a magnetically activated locking mechanism and a device with which a proof of a manipulation attempt is to provide.
- the materials can be adjusted by further additional elements and the processing by, for example, annealing to an intended value of the coercive force, so that at the locking mechanism of the lock cylinder near installation location of the detector an interference field strength can already be detected below the field strength required for manipulation.
- the materials mentioned have a substantially rectangular magnetization loop, the so-called bh characteristic.
- the detection of the manipulation experiment with the strong external magnetic field can be done by changing the magnetization of the detector in terms of magnitude and direction, which causes the magnetic field.
- the magnetic pattern in unmodified state and strong from the outside Magnetic field changed state can be detected for example with a Hall sensor or with a so-called magnetic eye. Likewise, the detection can be done optically via special ferrofluidic films.
- the detector element contributes according to another advantageous development of the invention to protect the lock cylinder against drilling when the detector element is arranged in the housing between the end face and the locking mechanism.
- pins designed as a detector element can be pressed into the housing of the lock cylinder instead of generally known drill protection pins.
- the detector is designed as Bohrschutzelement.
- the detector is structurally particularly simple if the magnetic pattern of the detector is arranged in the detector element.
- the proposed pattern can be combined in a particularly simple manner by arranging a plurality of detector elements arranged in a distributed manner with an intended magnetic alignment.
- the magnetic pattern of the detector can be formed by the detector elements, which themselves have a magnetic alignment. For example, if two detector elements arranged next to one another have opposite magnetic fields Orientations on, the alignments are re-magnetized, for example, in an external magnetic field, so that they are aligned in the same direction.
- the magnetic alignments of the detector elements are changed when exposed to the strong magnetic field, whereby a manipulation attempt can be detected.

- the electromagnetically activatable locking mechanism 7 controls the mobility of the core 6 relative to the housing 5 in response to a key inserted into a closing channel 8 of the core 6. He may alternatively be designed as a clutch.
- the locking mechanism 7 has a locking bar 10 penetrating into a recess 9 of the core 6 and an electromagnet 11 for controlling the movability of the locking bolt 10 and is in the DE 199 01 838 A1 described in detail.
- the over the door 1 protruding end face of the lock cylinder 3 is surrounded by a rosette 12.
- the core 6 of the lock cylinder 3 is rotatably connected to a cam 13.
- the device 4 for detecting a manipulation attempt has a detector 14 with a single, arranged on the outside of the lock cylinder 3 detector element 15.
- the detector element 15 is as a foil formed and has a magnetic pattern, for example, a region-wise alternating magnetic polarity and is arranged substantially between the locking mechanism 7 and over the door 1 projecting end face of the lock cylinder 3.
- FIG. 2 shows the lock cylinder 3 FIG. 1 with the rosette 12 in a view of his over the door 1 protruding front page.
- the detector 14 may also have a plurality of detector elements 15 or be arranged on the rosette 12 visible or invisible. Also conceivable is the arrangement of the detector 14 on the lock case 2 or on the door 1.
- FIG. 3 shows a lock cylinder 17 with a plurality of detector elements 18 having detector 19.
- the detector elements 18 are arranged in a housing 20 and in a core of the lock cylinder 17.
- the detector elements 18 are formed as pins and may have a different orientation of their magnetic poles to produce the magnetic pattern. In a strong external magnetic field, the orientation of the magnetic poles of the detector elements 18 is changed and can be easily detected, for example, by Hall elements.

- FIG. 5a shows a detector element 24 for use in the detectors 14, 19 of the FIGS. 1 to 4 during the generation of a magnetic pattern.
- a provided for generating the magnetic pattern punch 25 with a return plate 26 and disposed thereon permanent magnet 27 is used with different magnetization directions.

- the detector element 24 is provided with a magnetic pattern, which, for example, by means of an applied to the detector element 24 and in FIG. 5b shown ferrofluid film 28 can be detected.
- the ferrofluidic film 28 makes the magnetic pattern produced by the stamp 25 visible through a different coloration, which is illustrated in the drawing by a different hatching.
- the magnetic pattern generated by the punch 25 is destroyed, so that the ferrofluid film 28 placed on the detector element 24 shows a distinctly different coloration, as shown in FIG. 5c is shown.

Abstract
Description
Die Erfindung betrifft eine Kombination eines Schließzylinders mit einem magnetisch aktivierbaren Sperrmechanismus und einer Vorrichtung zum Nachweis eines Manipulationsversuches mit einem starken äußeren Magnetfeld.The invention relates to a combination of a lock cylinder with a magnetically activated locking mechanism and a device for detecting a manipulation attempt with a strong external magnetic field.
Schließzylinder mit einem magnetisch aktivierbaren Sperrmechanismus sind beispielsweise aus der

Mit heutigen Selten-Erden-Dauermagneten können jedoch sehr große Störfelder im Bereich bis zu einem Tesla im Abstand von einigen Zentimetern erzeugt werden. Solche Felder lassen sich oft, bedingt durch die Bauart oder die Einbauposition des magnetisch aktivierbaren Sperrmechanismus nicht zuverlässig abschirmen, da zur Abschirmung eingesetzte ferromagnetische Materialien durch solche Störfelder magnetisch in Sättigung gebracht werden können.With today's rare earth permanent magnets, however, very large interference fields in the range up to a Tesla can be generated at a distance of a few centimeters. Such fields can often not be shielded reliably due to the design or the installation position of the magnetically activatable locking mechanism, since ferromagnetic materials used for shielding can be magnetically brought into saturation by such interference fields.
Daher ist es häufig wünschenswert, einen Nachweis über eine versuchte Manipulation des Schließzylinders mit einem starken magnetischen Störfeld zu führen. Der Nachweis sollte dabei bereits unterhalb jener Feldstärke ansprechen, bei welcher der Sperrmechanismus beeinflusst wird und anderseits einen entsprechenden Abstand zu in der Umgebung allgemein vorherrschenden magnetischen Feldern aufweisen.Therefore, it is often desirable to provide evidence of attempted manipulation of the lock cylinder with a strong magnetic noise field. In this case, the detection should already respond below the field strength at which the blocking mechanism is influenced and, on the other hand, have a corresponding distance from the magnetic fields generally prevalent in the environment.
Der Erfindung liegt daher das Problem zugrunde, eine Kombination eines Schließzylinders mit einem magnetisch aktivierbaren sperrmechanismus und einer Vorrichtung zu schaffen, mit der ein Nachweis eines Manipulationsversuch zu erbringen ist.The invention is therefore based on the problem to provide a combination of a lock cylinder with a magnetically activated locking mechanism and a device with which a proof of a manipulation attempt is to provide.
Dieses Problem wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This problem is solved by the features of
Durch diese Gestaltung kann ein ausreichend starkes Magnetfeld zu der Zerstörung des magnetischen Musters des Detektors führen. Zur Erzeugung des Musters kann beispielsweise das Detektorelement das Muster selbst aufweisen. Bei einem ausreichend starken äußeren Magnetfeld kann das Detektorelement ummagnetisiert und damit das Muster zerstört werden. Weiterhin kann das Detektorelement im entmagnetisierten Zustand eingesetzt werden und von dem starken äußeren Magnetfeld in irgendeiner Weise magnetisiert werden. Als Detektor geeignete Werkstoffe sind beispielsweise Eisen-Chrom-Kobalt-Nickel-Legierungen mit Koerzitivfeldstärke im Bereich von 1 bis 60 kA/m und sind unter den Handelsnamen Magnetoflex, Sensorvac oder Semivac bekannt. Die Werkstoffe können durch weitere Zusatzelemente sowie die Verarbeitung durch beispielsweise Glühen auf einen vorgesehenen Wert der Koerzitivfeldstärke eingestellt werden, so dass am dem Sperrmechanismus des Schließzylinders nahen Einbauort des Detektors eine Störfeldstärke bereits unterhalb der zur Manipulation erforderlichen Feldstärke erfasst werden kann. Die genannten Materialien besitzen eine im Wesentlichen rechteckförmige Magnetisierungsschleife, die so genannte b-h-Kennlinie. Der Nachweis des Manipulationsversuchs mit dem starken äußeren Magnetfeld kann durch die Änderung der Magnetisierung des Detektors nach Betrag und Richtung erfolgen, welche das Magnetfeld hervorruft. Das magnetische Muster im unveränderten Zustand und im von dem äußeren starken Magnetfeld veränderten Zustand kann beispielsweise mit einem Hallsensor oder mit einem sogenannten magnetischen Auge nachgewiesen werden. Ebenso kann der Nachweis optisch über spezielle Ferrofluidfolien erfolgen. Wird eine solche Ferrofluidfolie auf den Detektor aufgebracht, so reichern sich die in einer darin befindlichen Flüssigkeit suspendierten magnetischen Teilchen im Bereich großer magnetischer Feldstärken an und führen zu einer Verfärbung in Abhängigkeit von den unterschiedlichen Feldstärken des Detektors. Weiterhin kann der Nachweis auch durch magneto-optisch aktive Schichten erfolgen, deren optische Eigenschaften, wie beispielsweise der Brechungsindex, von der vorhandenen Magnetfeldstärke abhängt. Durch eine Beleuchtung mit polarisiertem Licht kann indirekt das Magnetfeld sichtbar gemacht werden.By virtue of this configuration, a sufficiently strong magnetic field can lead to the destruction of the magnetic pattern of the detector. To generate the pattern, for example, the detector element may have the pattern itself. With a sufficiently strong external magnetic field, the detector element can be re-magnetized and thus the pattern destroyed. Furthermore, the detector element can be used in the demagnetized state and be magnetized by the strong external magnetic field in any way. Materials suitable as detector are, for example, iron-chromium-cobalt-nickel alloys with coercive force in the range from 1 to 60 kA / m and are known under the trade names Magnetoflex, Sensorvac or Semivac. The materials can be adjusted by further additional elements and the processing by, for example, annealing to an intended value of the coercive force, so that at the locking mechanism of the lock cylinder near installation location of the detector an interference field strength can already be detected below the field strength required for manipulation. The materials mentioned have a substantially rectangular magnetization loop, the so-called bh characteristic. The detection of the manipulation experiment with the strong external magnetic field can be done by changing the magnetization of the detector in terms of magnitude and direction, which causes the magnetic field. The magnetic pattern in unmodified state and strong from the outside Magnetic field changed state can be detected for example with a Hall sensor or with a so-called magnetic eye. Likewise, the detection can be done optically via special ferrofluidic films. If such a ferrofluid film is applied to the detector, the magnetic particles suspended in a liquid contained therein accumulate in the region of high magnetic field strengths and lead to discoloration as a function of the different field strengths of the detector. Furthermore, the detection can also be carried out by magneto-optically active layers whose optical properties, such as the refractive index, on the existing magnetic field strength depends. By illuminating with polarized light, the magnetic field can indirectly be made visible.
Die Montage des Detektorelementes erfordert gemäß einer vorteilhaften Weiterbildung der Erfindung einen besonders geringen Aufwand, wenn das Detektorelement als Detektorfolie ausgebildet ist. Die vorstehend genannten Materialien eignen sich durch ihre gute Kaltverformbarkeit zur Erzeugung von Folien vorzugsweise in einem Dickenbereich unter 100 µm und sind gegen mechanische Beanspruchung weitgehend unempfindlich.The assembly of the detector element requires according to an advantageous embodiment of the invention, a particularly low cost when the detector element is designed as a detector film. Due to their good cold workability for the production of films, the abovementioned materials are preferably suitable in a thickness range below 100 μm and are largely insensitive to mechanical stress.
Der Detektor weist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine hohe Stabilität auf, wenn das Detektorelement als Stift oder Platte ausgebildet ist.The detector has according to another advantageous embodiment of the invention, a high stability, when the detector element is designed as a pin or plate.
Vorhandene Schließanlagen lassen sich mit der erfindungsgemäßen Vorrichtung einfach nachrüsten, wenn das Detektorelement an dem Schließzylinder, im Bereich eines den Schließzylinder aufnehmenden Schlosskastens oder einer den Schließzylinder umschließenden Rosette angeordnet ist.Existing locking systems can be easily retrofitted with the device according to the invention, when the detector element to the lock cylinder, in the region of a lock cylinder receiving the lock case or a the lock cylinder surrounding rosette is arranged.
Das Detektorelement trägt gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zum Schutz des Schließzylinders gegen ein Aufbohren bei, wenn das Detektorelement im Gehäuse zwischen der Stirnseite und dem Sperrmechanismus angeordnet ist. Hierfür können beispielsweise als Detektorelement ausgebildete Stifte anstelle allgemein bekannter Bohrschutzstifte in das Gehäuse des Schließzylinders eingepresst werden. Damit ist der Detektor als Bohrschutzelement ausgebildet.The detector element contributes according to another advantageous development of the invention to protect the lock cylinder against drilling when the detector element is arranged in the housing between the end face and the locking mechanism. For this purpose, for example, pins designed as a detector element can be pressed into the housing of the lock cylinder instead of generally known drill protection pins. Thus, the detector is designed as Bohrschutzelement.
Der Nachweis des Manipulationsversuchs gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn das Detektorelement eine magneto-optische Oberfläche aufweist und an einem von au-ßerhalb des Schließzylinders sichtbaren Bereich angeordnet ist.According to another advantageous development of the invention, the proof of the manipulation attempt is particularly simple if the detector element has a magneto-optical surface and is arranged on a region visible from outside the lock cylinder.
Der Detektor gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das magnetische Muster des Detektors in dem Detektorelement angeordnet ist.According to another advantageous development of the invention, the detector is structurally particularly simple if the magnetic pattern of the detector is arranged in the detector element.
Das vorgesehene Musters lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung durch eine Anordnung von mehreren, verteilt angeordneten Detektorelementen mit einer vorgesehenen magnetischen Ausrichtung besonders einfach zusammenstellen. Hierdurch kann das magnetische Muster des Detektors von den selbst eine magnetische Ausrichtung aufweisenden Detektorelementen gebildet werden. Weisen beispielsweise zwei nebeneinander angeordnete Detektorelemente einander gegensinnige magnetische Ausrichtungen auf, werden die Ausrichtungen bei einem äußeren Magnetfeld beispielsweise ummagnetisiert, so dass sie gleichsinnig ausgerichtet sind. Damit werden bei der Einwirkung des starken Magnetfeldes die magnetischen Ausrichtungen der Detektorelemente geändert, womit sich ein Manipulationsversuch erfassen lässt.According to another advantageous development of the invention, the proposed pattern can be combined in a particularly simple manner by arranging a plurality of detector elements arranged in a distributed manner with an intended magnetic alignment. As a result, the magnetic pattern of the detector can be formed by the detector elements, which themselves have a magnetic alignment. For example, if two detector elements arranged next to one another have opposite magnetic fields Orientations on, the alignments are re-magnetized, for example, in an external magnetic field, so that they are aligned in the same direction. Thus, the magnetic alignments of the detector elements are changed when exposed to the strong magnetic field, whereby a manipulation attempt can be detected.
Zur Erhöhung der Zuverlässigkeit der Erfassung eines Manipulationsversuchs trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn mehrere Detektorelemente in einer Reihe angeordnet sind. Das magnetische Muster des Detektors kann dabei von den einzelnen Detektorelementen zusammengesetzt werden.To increase the reliability of the detection of a manipulation attempt, it contributes, according to another advantageous embodiment of the invention, when a plurality of detector elements are arranged in a row. The magnetic pattern of the detector can be composed of the individual detector elements.
