Description

Die Erfindung betrifft einen Schließzylinder und einen Schlüssel gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lock cylinder and a key according to the preamble of claim 1.

Schließzylinder der im Oberbegriff des Anspruchs 1 genannten Art sind z.B. in der DE 1921515 A1 beschrieben.Lock cylinder referred to in the preamble of claim 1 are, for example, in the DE 1921515 A1 described.

Schließzylinder, sogenannte Magnetschlösser, sind bekannt und detailliert z.B. in den AT-PS Nr. 341901 und Nr. 357430 beschrieben. Wesentliche Merkmale dieser und ähnlicher Schlösser sind Drehzuhaltungen bzw. Abfrageelemente in Form von Magnetrotoren, deren Drehlage entsprechend der magnetischen Codierung zugehöriger Schlüsselmagnete einstellbar ist, wobei die richtige Drehstellung der Magnetrotoren durch Abtastelemente des Schlosses abgetastet werden. Bei richtiger Drehstellung kann das Abtastelement in eine Ausnehmung des Magnetrotors eingeschoben werden und die Verschiebebewegung steuert ihrerseits ein Sperrelement, das die Sperrung des Schlosses bewirkt bzw. ein Verdrehen des Schlosses zulässt. Die Bewegungsrichtung des Abtastelements kann jede beliebige Richtung haben und verläuft in der Praxis überwiegend in Richtung des Radius des Magnetrotors, kann aber auch in axialer Richtung des Magnetrotors verlaufen. Derartige Schlösser können Zylinderschlösser oder auch Schiebeschlösser sein. Bei Zylinderschlössern sind die Magnetrotoren in Ausnehmungen des Zylinderkerns gelagert und die genannten Abtastelemente wirken einerseits mit den Magnetrotoren und anderseits mit Verrastungselementen des Zylindergehäuses zusammen, um das Entsperren oder Sperren zu bewirken.Locking cylinders, so-called magnetic locks, are known and described in detail e.g. in AT-PS Nos. 341901 and 357430. Essential features of these and similar locks are tumblers or query elements in the form of magnetic rotors whose rotational position corresponding to the magnetic encoding associated key magnets is adjustable, the correct rotational position of the magnet rotors are scanned by sensing elements of the castle. At the correct rotational position, the sensing element can be inserted into a recess of the magnet rotor and the sliding movement in turn controls a blocking element which causes the lock of the lock or allows a rotation of the lock. The direction of movement of the scanning element can have any direction and in practice runs predominantly in the direction of the radius of the magnet rotor, but can also run in the axial direction of the magnet rotor. Such locks can be cylinder locks or sliding locks. In the case of cylinder locks, the magnet rotors are mounted in recesses of the cylinder core and the mentioned scanning elements cooperate on the one hand with the magnet rotors and on the other hand with latching elements of the cylinder housing in order to effect the unlocking or locking.

Nachteilig bei den beschriebenen Magnetschlössern ist der Umstand, dass von den im Schlüssel angeordneten Schlüsselmagneten ein starkes Magnetfeld ausgeht, das in der Lage ist, die magnetische Codierung von beispielsweise scheckkartenförmigen Magnetkarten zu beeinträchtigen. Insbesondere, wenn derartige Magnetschlüssel längere Zeit in der Nähe des Magnetstreifens solcher Karten zu liegen kommen, besteht die Gefahr eines vollständigen Verlustes der magnetcodierten Kartendaten.A disadvantage of the magnetic locks described is the fact that emanating from the key magnets arranged in the key a strong magnetic field, which is able to affect the magnetic encoding of example credit card-shaped magnetic cards. In particular, if such magnetic key for a long time in the vicinity of the magnetic stripe such Cards come to lie, there is the danger of a complete loss of the magnetic-coded map data.

Die Erfindung zielt daher darauf ab, Magnetschlösser der eingangs genannten Art derart zu verbessern, dass vom Schlüssel möglichst kein Magnetfeld ausgeht, wobei gleichzeitig aber die überaus hohe Sicherheit und Codierungsvielfalt von Magnetschlössern beibehalten werden soll.The invention therefore aims to improve magnetic locks of the type mentioned in such a way that no possible magnetic field emanates from the key, but at the same time the extremely high security and coding diversity of magnetic locks should be maintained.

Zur Lösung dieser Aufgabe besteht die Erfindung bei einer Kombination eines Schließzylinders mit einem Schlüssel der eingangs genannten Art im wesentlichen darin, dass der Schließzylinder mit einem Gehäuse und darin verdrehbarem, einen Schlüsselkanal aufweisenden Zylinderkern ausgebildet ist, wobei wenigstens ein beweglich angeordnetes, durch eine magnetische Kraft bewegbares Abfrageelement und wenigstens ein die Stellung des Abfrageelements abtastendes Abtastelement vorgesehen sind, das mit wenigstens einem Verrastungselement des Schließzylinders zusammenwirkt, um das Entsperren oder Sperren zu bewirken, wobei der Schließzylinder, insbesondere der Zylinderkern von dem Abfrageelement verschiedene Mittel zum Erzeugen eines den Schlüsselkanal durchsetzenden magnetischen Flusses aufweist, durch welchen das wenigstens eine beweglich angeordnete Abfrageelement bewegbar ist, und dass der Schlüssel mit einer Reide und einem Schlüsselbart ausgebildet ist, wobei der Schlüsselbart aus einem Material mit hohem magnetischen Widerstand besteht und von wenigstens einem nicht-magnetisierten Bereich niedrigeren magnetischen Widerstands durchsetzt ist, der an der Schlüsseloberfläche wenigstens eine Feldeintrittsstelle und wenigstens eine Feld-austrittsstelle ausbildet, wobei in der in den Schlüsselkanal eingeschobenen Position des Schlüssels den Feldaustrittsstellen der nicht-magnetisierten Bereiche niedrigeren magnetischen Widerstands des Schlüssels jeweils ein durch die magnetische Kraft bewegbares Abfrageelement zugeordnet ist.To achieve this object, the invention consists in a combination of a lock cylinder with a key of the type mentioned essentially in that the lock cylinder is formed with a housing and rotatable, a key channel having cylinder core, wherein at least one movably arranged, by a magnetic force movable interrogation element and at least one sensing element scanning the sensing element are provided which cooperates with at least one latching element of the lock cylinder to effect the unlocking or locking, wherein the lock cylinder, in particular the cylinder core of the query element different means for generating a key channel passing magnetic River, through which the at least one movably arranged query element is movable, and that the key is formed with a Reide and a key bit, wherein the key bit au s is a material having a high magnetic resistance and is penetrated by at least one non-magnetized region of lower magnetic resistance, which forms at least one field entry point and at least one field exit point on the key surface, wherein in the inserted into the key channel position of the key the field exit points of the non-magnetized areas of lower magnetic resistance of the key is assigned in each case a movable by the magnetic force query element.

Die Mittel zum Erzeugen des magnetischen Flusses, der von den Abfrageelementen im Schließzylinder herangezogen wird, um die Codierung des Schlüssels zu überprüfen, sind somit im Unterschied zu den herkömmlichen Magnetschlössern nicht im Schlüssel, sondern lediglich im Schließzylinder angeordnet. Die Mittel zum Erzeugen des magnetischen Flusses sind derart angeordnet, dass der magnetische Fluss den Schlüsselkanal durchsetzt, wobei dies insbesondere bei in den Schlüsselkanal eingeschobenen Schlüssel der Fall sein soll, wobei der den Schlüssel durchsetzende magnetische Fluss durch weiter unten noch näher beschriebene Codierungselemente des Schlüssels derart geleitet wird, dass die im Zylinderkern angeordneten, magnetisch arbeitenden Abfrageelemente die entsprechende Codierung abfragen können, wobei im Fall eines zutrittsberechtigten Schlüssels das Sperren oder Entsperren freigegeben wird.The means for generating the magnetic flux, which is used by the query elements in the lock cylinder to check the coding of the key are thus, unlike the conventional magnetic locks not in the key, but only arranged in the lock cylinder. The means for generating the magnetic flux are arranged such that the magnetic flux passes through the key channel, this being the case in particular when the key is inserted into the key channel, the magnetic flux passing through the key being described in greater detail below by coding elements of the key is directed that arranged in the cylinder core, magnetically operating query elements can query the appropriate coding, in the case of an authorized key locking or unlocking is released.

Bevorzugt sind die Mittel zum Erzeugen des magnetischen Flusses von einem Permanentmagneten gebildet. Der Permanentmagnet kann beispielsweise an lediglich einer Seite des Schlüsselkanals im Zylinderkern angeordnet werden, wobei die Anordnung bevorzugt derart erfolgt, dass ein Magnetkreis im Schließzylinderkern mit einem möglichst geringen magnetischen Kreiswiderstand geschlossen werden kann, sodass auch mit einem schwächeren Permanentmagneten des Auslangen gefunden werden kann. Bevorzugt ist der Permanentmagnet hierbei dem Schlüsselkanal unmittelbar benachbart, damit sich der magnetische Kreis bei eingestecktem Schlüssel mit möglichst kleinem magnetischen Widerstand schließt und die Funktionssicherheit gesteigert werden kann. Dabei können Bereiche mit höherem magnetischen widerstand im magnetischen Kreis, wie beispielsweise die Übergangsstelle von der Schließzylinderkerninnenseite auf den Schlüssel derart optimiert werden, dass die Längen dieser Stellen möglichst klein gehalten werden. Gemäß einer bevorzugten Ausführungsform weist der Permanentmagnet hierbei eine Rechteckquerschnittsform auf. Um magnetische Straufelder im Zylinderkern zu minimieren, sieht eine bevorzugte Ausbildung vor, dass der Zylinderkern, insbesondere der Zylinderkernmantel aus einem einen hohen magnetischen Widerstand aufweisenden Material besteht, insbesondere aus einem Material, z.B. Messing, das einen höheren magnetischen Widerstand aufweist als Eisen. Der Magnetkreis kann insbesondere dann mit einem möglichst geringen magnetischen Widerstand geschlossen werden, wenn wie es einer weiteren bevorzugten Ausbildung entspricht, der Zylinderkern wenigstens einen Bereich aus ferromagnetischem Material aufweist, der mit dem Permanentmagneten zur Ausbildung eines Magnetkreises zusammenwirkt.
Das durch den den Schlüsselkanal durchsetzenden magnetischen Fluss bewegbare Abfrageelement ist bevorzugt von einem Magnetrotor gebildet. Unter einem Magnetrotor ist hierbei ein rotierender Bauteil zu verstehen, der ein ferromagnetisches Material oder einen Permanentmagneten aufweist und der zu den den Schlüsselkanal durchsetzenden magnetischen Feldlinien derart ausgerichtet ist, dass sich der Rotor in eine vorgegebene Drehstellung den Flusslinien entsprechend ausrichtet. Bevorzugt sind eine Mehrzahl von beweglich angeordneten, durch eine magnetische Kraft bewegbare Abfrageelemente entlang der Längserstreckung des Schlüsselkanals angeordnet. Je höher die Anzahl der Abfrageelemente ist, desto größer ist die maximale Anzahl von verschiedenen Schlüsselcodierungen. Die Abfrageelemente können hierbei lediglich an einer Seite des Schlüsselkanals angeordnet sein. Besonders bevorzugt ist eine Ausbildung, bei welcher die Abfragelemente an zwei gegenüberliegenden Seiten des Schlüsselkanals angeordnet sind, sodass auch auf kleinstem Raum eine möglichst große Anzahl an Abfrageelementen Platz finden kann.Preferably, the means for generating the magnetic flux are formed by a permanent magnet. The permanent magnet can be arranged, for example, on only one side of the key channel in the cylinder core, wherein the arrangement is preferably such that a magnetic circuit in the lock cylinder core can be closed with the lowest possible magnetic resistance, so that even with a weaker permanent magnet of Auslangen can be found. Preferably, the permanent magnet is in this case the key channel immediately adjacent, so that closes the magnetic circuit with inserted key with the smallest possible magnetic resistance and the reliability can be increased. In this case, areas with higher magnetic resistance in the magnetic circuit, such as the transition point from the lock cylinder core inside to the key can be optimized so that the lengths of these locations are kept as small as possible. According to a preferred embodiment has the permanent magnet in this case has a rectangular cross-sectional shape. In order to minimize magnetic Straufelder in the cylinder core, a preferred embodiment provides that the cylinder core, in particular the cylinder core casing is made of a high magnetic resistance material, in particular of a material, such as brass, which has a higher magnetic resistance than iron. The magnetic circuit can be closed in particular with the lowest possible magnetic resistance if, as it corresponds to a further preferred embodiment, the cylinder core has at least one region of ferromagnetic material which cooperates with the permanent magnet to form a magnetic circuit.
The interrogator element movable by the magnetic flux passing through the key channel is preferably formed by a magnet rotor. A magnetic rotor here is to be understood as meaning a rotating component which has a ferromagnetic material or a permanent magnet and which is aligned with the magnetic field lines passing through the key channel in such a way that the rotor aligns with the flux lines in a predetermined rotational position. Preferably, a plurality of movably arranged, movable by a magnetic force query elements along the longitudinal extension of the keyway are arranged. The higher the number of query elements, the greater the maximum number of different key encodings. The query elements may in this case be arranged only on one side of the key channel. Particularly preferred is an embodiment in which the interrogation elements are arranged on two opposite sides of the key channel, so that as large a number of query elements can find space even in the smallest space.

Im Zusammenhang mit dem Schlüssel ist vorgesehen, dass der Schlüsselbart aus einem Material mit hohem magnetischen Widerstand besteht und von wenigstens einem nicht-magnetisierten Bereich niedrigeren magnetischen Widerstands durchsetzt ist, der an der Schlüsseloberfläche wenigstens eine Flusseintrittsstelle und wenigstens eine Flussaustrittsstelle ausbildet. Der Begriff "nicht-magnetisiert" schließt hierbei auch eine allfällige geringe Magnetisierung ein, wie sie beispielsweise in Folge von Remanenzerscheinungen auftreten kann. Es ist somit ersichtlich, dass der Schlüssel kein oder nur schwach magnetisiertes Material aufweist, sodass vom Schlüssel kein signifikantes Magnetfeld ausgeht, das beispielsweise Magnetkarten beeinträchtigen könnte. Die Codierung des Schlüssels erfolgt nun derart, dass im Material des Schlüssels nicht-magnetisierte Bereiche niedrigeren magnetischen Widerstands angeordnet sind, durch welche bei in den Schlüsselkanal eingeschobenem Schlüssel der beispielsweise vom Permanentmagneten des Zylinderkerns ausgehend magnetische Fluss geleitet wird. Die Anordnung der nicht-magnetisierten und mit niedrigem magnetischen Widerstand ausgebildeten Schlüsselbereiche und insbesondere deren Verlauf sowie die Position und die Orientierung der an der Schlüsseloberfläche angeordneten Flussein- und Flussaustrittsstellen der genannten Bereiche bestimmen dabei die jeweilige Schlüsselcodierung.In connection with the key, it is provided that the key bit is made of a material having a high magnetic resistance and is penetrated by at least one non-magnetized region of lower magnetic resistance, which forms at least one flow entry point and at least one flow exit point on the key surface. The term "non-magnetized" in this case also includes a possible low magnetization, as it can occur, for example, as a result of remanence phenomena. It can thus be seen that the key has no or only weakly magnetized material, so that no significant magnetic field originates from the key, which could impair, for example, magnetic cards. The coding of the key is now carried out such that non-magnetized areas of lower magnetic resistance are arranged in the material of the key, through which, in the key channel inserted key, for example, from the permanent magnet of the cylinder core starting magnetic flux is passed. The arrangement of the non-magnetized and formed with low magnetic resistance key areas and in particular their course and the position and orientation of arranged on the key surface Flussein- and river exit points of said areas determine the respective key encoding.

Die den Schlüssel durchsetzenden, nicht-magnetisierten, mit niedrigem magnetischen Widerstand ausgebildeten Bereiche können dabei derart durch den Schlüssel verlaufen, dass die Feldeinund die Feldaustrittsstelle an der selben Schlüsselseite angeordnet sind. Bevorzugt ist jedoch eine Ausbildung, bei welcher der wenigstens eine Bereich niedrigeren magnetischen Widerstands die Feldeintrittsstelle und die Feldaustrittsstelle an gegenüberliegenden Seiten des Schlüssels aufweist. Bevorzugt ist weiters vorgesehen, dass die Feldeintrittsstelle gegenüber der Feldaustrittsstelle in einer Richtung quer zur Schlüsseloberflächennormalen versetzt angeordnet ist.
Die geometrische Form der Feldein- und Feldaustrittsstellen sowie deren Position bestimmen den Verlauf und den gekoppelten magnetischen Fluss der ein- bzw. austretenden magnetischen Feldlinien, wodurch die jeweilige Position der Magnetrotoren bzw. der Abfrageelemente beeinflusst wird. Eine bevorzugte Ausbildung sieht in diesem Zusammenhang vor, dass der nicht-magnetisierte Bereich niedrigeren magnetischen Widerstands an der Feldaustrittsstelle einen Querschnitt aufweist, der gegenüber dem Querschnitt an der Feldeintrittsstelle verdreht ist. In diesem Zusammenhang sieht eine weitere bevorzugte Ausbildung vor, dass der nicht-magnetisierte Bereich niedrigeren magnetischen Widerstands an der Feldeintrittsstelle und ggf. an der Feldaustrittsstelle einen rechteckigen Querschnitt aufweist.The key-passing, non-magnetized, low-resistance regions formed may pass through the key such that the field and the field exit point are arranged on the same key side. However, an embodiment is preferred in which the at least one region of lower magnetic resistance has the field entry point and the field exit point on opposite sides of the key. Prefers is further provided that the field entry point is offset from the field exit point in a direction transverse to the key surface normal.
The geometric shape of the field entry and exit points as well as their position determine the course and the coupled magnetic flux of the incoming and outgoing magnetic field lines, whereby the respective position of the magnetic rotors or the interrogation elements is influenced. A preferred embodiment provides in this context that the non-magnetized Area of lower magnetic resistance at the field exit point has a cross section which is rotated relative to the cross section at the field entry point. In this connection, a further preferred embodiment provides that the non-magnetized region of lower magnetic resistance has a rectangular cross-section at the field entry point and possibly at the field exit point.

Zur Erhöhung der Schließsicherheit kann die erfindungsgemäß vorgesehene magnetische wirkende Codierung mit anderen Codierungsmöglichkeiten kombiniert sein, wobei insbesondere vorgesehen sein kann, dass der Schlüssel eine mit mechanischen Abfrageelementen in Wirkverbindung bringbare mechanische Kodierung, insbesondere Profilierung aufweist.To increase the security against locking, the inventively provided magnetic-acting coding can be combined with other coding possibilities, it being possible in particular for the key to have a mechanical coding, in particular profiling, which can be brought into operative connection with mechanical interrogation elements.

Die Erfindung wird nachfolgend an Hand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigt Fig.1 eine Seitenansicht eines erfindungsgemäßen Schlüssels, Fig.2 eine Querschnittansicht einer abgewandelten Ausbildung des Schlüssels, Fig.3 einen Querschnitt eines Schließzylinders mit in den Schlüsselkanal eingeschobenem Schlüssel und Fig.4 eine perspektivische Ansicht eines Magnetrotors.The invention will be explained in more detail with reference to embodiments schematically illustrated in the drawing. In this shows Fig.1 a side view of a key according to the invention, Fig.2 a cross-sectional view of a modified embodiment of the key, Figure 3 a cross section of a lock cylinder with inserted into the keyway key and Figure 4 a perspective view of a magnet rotor.

Der in Figur 1 dargestellte Schlüssel 1 weist eine Reide 2 sowie einen Schlüsselbart 3 auf. Der Schlüsselbart 3 besteht aus einem Material mit hohem magnetischen Widerstand und weist eine Mehrzahl von nicht-magnetisierten Bereichen 4 auf, die aus einem Material mit niedrigerem magnetischen Widerstand bestehen. Wie in der Querschnittsansicht gemäß Figur 2 ersichtlich ist, können die nicht-magnetisierten Bereiche 4 auf unterschiedliche Art und Weise durch den Schlüssel 1 verlaufen, wobei jeder Bereich 4 jeweils eine Feldeintrittsstelle 5 und eine Feldaustrittsstelle 6 aufweist. Die Feldein- und die Feldaustrittsstellen 5 und 6 können hierbei, wie insbesondere in Figur 2 ersichtlich ist, an gegenüberliegenden Seiten des Schlüssel angeordnet sein oder an der gleichen Seite des Schlüssels. Wie ebenfalls in Figur 2 ersichtlich ist, können die nicht-magnetisierten Bereiche 4 derart durch den Schlüssel verlaufen, dass die Feldein- und die Feldaustrittsstelle einen voneinander verschiedenen Querschnitt aufweisen, wobei der Feldeintrittsquerschnitt insbesondere gegenüber dem Feldaustrittsquerschnitt um die schematisch mit 7 angedeutete Achse verdreht angeordnet sein kann. Die Schlüsseloberfläche kann weiters eine die Feldein- und die Feldaustrittsstellen 5 und 6 der nicht-magnetisierten Bereiche 4 überdeckende Abdeckung aufweisen, sodass von außen nicht erkennbar ist, wo die einzelnen Feldeinund Feldaustrittsstellen angeordnet sind. Eine derartige Abdeckung kann beispielsweise aus nicht-transparentem Kunststoff oder dergleichen bestehen.The in FIG. 1 illustrated key 1 has a Reide 2 and a key bit 3. The key bit 3 is made of a high-resistance material and has a plurality of non-magnetized regions 4 made of a lower-resistance material. As in the cross-sectional view according to FIG. 2 As can be seen, the non-magnetized regions 4 can run in different ways through the key 1, each region 4 each having a field entry point 5 and a field exit point 6. The field entry and exit points 5 and 6 can here, in particular in FIG. 2 it can be seen on opposite sides of the key or on the same side of the key. Like also in FIG. 2 it can be seen, the non-magnetized regions 4 can pass through the key such that the field inlet and the field exit point have a different cross section, wherein the field inlet cross section can be arranged in particular rotated relative to the field exit cross section about the schematically indicated with 7 axis. The key surface may further comprise a field cover and the field exit points 5 and 6 of the non-magnetized areas 4 covering cover, so that it is not recognizable from the outside, where the individual field and field exit points are arranged. Such a cover may for example consist of non-transparent plastic or the like.

Das Material des Schlüssels 1 mit hohem magnetischen Widerstand kann beispielsweise Messing, Kupfer, Aluminium oder ein passender Kunststoff sein. Die nicht-magnetisierten Bereiche 4 geringen magnetischen Widerstands können beispielsweise aus einem ferromagnetischen Stoff, wie Eisen, Kobalt, Nickel sowie deren nicht als Permanentmagneten ausgeführten Legierungen, wie z.B. AlNiCo, SmCo, Nd2Fe14B, Ni80Fe20, NiFeCo oder auch aus entsprechend modifizierten Kunststoffen, z.B. mit Kohlenstoffnanoröhren, bestehen.The material of the key 1 with high magnetic resistance may be, for example brass, copper, aluminum or a matching plastic. The non-magnetized regions 4 of low magnetic resistance can be made, for example, of a ferromagnetic material, such as iron, cobalt, nickel and their non-permanent magnet alloys, such as AlNiCo, SmCo, Nd 2 Fe 14 B, Ni 80 Fe 20 , NiFeCo or from appropriately modified plastics, eg with carbon nanotubes exist.

In Figur 3 ist der um die Achse 8 drehbare Zylinderkern eines Schließzylinders mit 9 bezeichnet und weist einen Schlüsselkanal 10 auf. Im Schlüsselkanal 10 ist ein Schlüssel 1 angeordnet, der eine Mehrzahl nicht-magnetisierter Bereiche 4 mit niedrigem magnetischen Widerstand aufweist. Im Zylinderkern 9 ist ein ferromagnetischer Kreis 11 angeordnet, welcher den magnetischen Fluss mit kleinem magnetischen Widerstand durch den Zylinderkern leiten kann. Dabei richten sich die Magnetrotoren 12 entsprechend den Bereichen mit geringem magnetischen Widerstand im Schlüssel aus, wobei nicht dargestellte Abtastelemente die Stellung der Magnetrotoren 12 abfragen. Die Abtastelemente wiederum wirken mit einem nicht dargestellten Verrastungselement des Gehäuses zusammen, um das Entsperren oder Sperren zu bewirken.
In Fig.4 ist eine bevorzugte Ausführung eines Magnetrotors 12 dargestellt, wobei die Drehachse des Magnetrotors 12 so wie in Fig.3 mit 13 bezeichnet ist. Der Magnetrotor ist als Zylinder 14 ausgebildet und ist von einem Bereich 15 durchsetzt, der beispielsweise quaderförmig ausgebildet ist und sowohl an der Vorderseite des Magnetrotors als auch an der Hinterseite des Magnetrotors eine Feldeintritts- bzw. eine Feldaustrittsstelle aufweist. Der Bereich 15 ist entweder als Permanentmagnet ausgebildet und so magnetisiert, dass er sich durch Drehung entsprechend des Pfeils 16 nach dem den jeweils zugeordneten Bereich 4 des Schlüssels 1 durchsetzenden Magnetfeld ausrichtet, oder der Bereich 15 ist aus einem Material niedrigen magnetischen Widerstands ausgebildet, der sich ebenfalls nach dem den jeweils zugeordneten Bereich 4 des Schlüssels 1 durchsetzenden Magnetfeld ausrichten kann.
Es sind auch Ausführungen denkbar, bei denen der ferromagnetische Kreis 11 im Zylinderkern ganz oder teilwiese durch einen Permanentmagneten ersetzt ist und sich so die Magnetrotoren sich im Einklang mit dem Permanentmagneten 11 und den Bereich mit niedrigem magnetischen Widerstand im Schlüssel ausrichten. Diese Ausführung ist besonders störungsunanfällig, da durch die vielen Permanentmagneten eine höhere Feldstärke erreicht wird und daher auch die magnetische Kraftwirkung auf die Rotoren verstärkt wird.In FIG. 3 is the rotatable about the axis 8 cylinder core of a lock cylinder designated 9 and has a keyway 10 on. In the keyway 10, a key 1 is arranged, which has a plurality of non-magnetized regions 4 with low magnetic resistance. In the cylinder core 9, a ferromagnetic circuit 11 is arranged, which the magnetic flux with low magnetic resistance through the Cylinder core can conduct. In this case, the magnetic rotors 12 are aligned in accordance with the areas with low magnetic resistance in the key, not shown sensing elements query the position of the magnet rotors 12. The sensing elements, in turn, cooperate with a detent element, not shown, of the housing to effect unlocking or locking.
In Figure 4 a preferred embodiment of a magnet rotor 12 is shown, wherein the axis of rotation of the magnet rotor 12 as in Figure 3 is denoted by 13. The magnet rotor is designed as a cylinder 14 and is penetrated by a region 15 which is, for example, of cuboid shape and has a field entry point or a field exit point both on the front side of the magnet rotor and on the rear side of the magnet rotor. The region 15 is either designed as a permanent magnet and magnetized so that it aligns by rotation according to the arrow 16 by the respective assigned region 4 of the key 1 passing magnetic field, or the region 15 is formed of a material of low magnetic resistance, the can also align according to the each assigned area 4 of the key 1 passing magnetic field.
Embodiments are also conceivable in which the ferromagnetic circle 11 in the cylinder core is completely or partially replaced by a permanent magnet and thus the magnet rotors align themselves in accordance with the permanent magnet 11 and the area with low magnetic resistance in the key. This embodiment is particularly susceptible to interference, since a higher field strength is achieved by the many permanent magnets and therefore also the magnetic force acting on the rotors is amplified.

Es sind auch Ausführungen denkbar, bei denen der Bereich 11 vollständig aus einem Permanentmagneten besteht, oder teilweise auch aus einem Material mit niedrigem magnetischen Widerstand. Die Rotoren weisen Bereiche mit niedrigem magnetischen Widerstand auf, wodurch sich die Rotoren mit ihren Bereichen geringen magnetischen Widerstands nach den Bereichen geringen magnetischen Widerstands im Schlüssel und Zylinderkern ausrichten. Vorteilhaft bei dieser Ausführung ist, dass die Permanentmagneten in den Rotoren entfallen können und durch billigere Bereiche geringen magnetischen Widerstands ersetzt werden können.Embodiments are also conceivable in which the region 11 consists entirely of a permanent magnet, or partially also of a material with a low magnetic resistance. The rotors have areas of low magnetic resistance, thereby aligning the rotors with their areas of low magnetic resistance to the areas of low magnetic resistance in the key and cylinder core. An advantage of this design is that the permanent magnets can be omitted in the rotors and can be replaced by cheaper areas of low magnetic resistance.
