Abstract

A cylinder housing has a cylinder core (1) that is provided with a key channel (8) for inserting a key (2). A locking pin (5) provided in a blocking position of the key channel is projected, such that complete insertion of key is prevented. An auxiliary locking pin is arranged relative to a magnet (3) in the key corresponding to unpolarized magnet (6) in cylinder core. The locking pin is moved from the locking position, when the magnet in the key is operated against the action of the magnet (4) that is arranged at the cylinder bore or the cylinder housing.

Description

Die Erfindung betrifft einen mit einem Schlüssel zu betätigenden Schließzylinder, mit einem im Zylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zum Einführen eines Schlüssels aufweist und wobei im Zylinderkern, wie auch dem Zylindergehäuse, miteinander und mit dem Schlüssel zusammenwirkende Kern - und Gehäusezuhaltungen vorgesehen sind, nach dem Oberbegriff des Anspruchs 1 sowie einen Schlüssel, der zum Zusammenwirken mit einem derartigen Schließzylinder ausgebildet ist, nach Anspruch 9.The invention relates to a lock cylinder to be actuated with a key, having a cylinder core rotatably mounted in the cylinder housing, which has a key channel for inserting a key, and wherein core and housing tumblers cooperating with each other and with the key are provided in the cylinder core, as well as the cylinder housing. according to the preamble of claim 1 and a key which is designed to cooperate with such a lock cylinder, according to claim 9.

Bei den üblichen Schließzylindern, mit einem drehbar im Zylindergehäuse gelagerten Zylinderkern, sind die Zuhaltungen so angeordnet, dass sie durch das seitliche Profil des Schlüssels oder die Kerben in der Schlüsselbrust verschoben werden, wobei diese Verschiebung zu einem Abgleich der Gehäuse- und Kernzuhaltungen an der Trennebene zwischen Zylinderkern und Zylindergehäuse führt.In the conventional lock cylinders, with a cylinder core rotatably mounted in the cylinder housing, the tumblers are arranged to be displaced by the lateral profile of the key or the notches in the key-chest, this displacement to balance the housing and core tumblers at the parting plane between the cylinder core and the cylinder housing leads.

Während ohne einen eingeführten Schlüssel die Zuhaltungen diese Trennebene übertreten und so eine Drehung des Zylinderkernes verhindern, kann mit einem passend codierten Schlüssel der Zylinderkern gedreht und damit ein Schließvorgang ausgelöst werden.While the tumblers transgress this parting plane without an inserted key and thus prevent a rotation of the cylinder core, the cylinder core can be turned with a suitably coded key, thus triggering a closing process.

Voraussetzung hierfür ist allerdings, dass der Schlüssel vollständig in den Schlüsselkanal einführbar ist, damit alle zusammenwirkenden Kerben, Profilbereiche und Zuhaltungen korrekt ausgerichtet sind.The prerequisite for this, however, is that the key can be inserted completely into the keyway so that all interacting notches, profile areas and tumblers are correctly aligned.

Manipulationen eines derartigen Schließzylinders sind mit geeigneten Werkzeugen möglich, weil auch dieses Werkzeug im allgemeinen vollständig in den Schlüsselkanal einführbar ist.Manipulations of such a lock cylinder are possible with suitable tools, because this tool is generally completely inserted into the keyway.

Aufgabe der Erfindung ist es, die Sicherheit einer Schloss-Schlüsselkombination mit einem derartigen Schließzylinder zu erhöhen.The object of the invention is to increase the security of a lock-key combination with such a lock cylinder.

Gelöst wird diese Aufgabe erfindungsgemäß bei einem mit einem Schlüssel zu betätigenden Schließzylinder, mit einem im Zylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zu Einführen eines Schlüssels aufweist und wobei im Zylinderkern wie auch dem Zylindergehäuse miteinander und mit dem Schlüssel zusammenwirkende Kern - und Gehäusezuhaltungen vorgesehen sind, dadurch, dass im oder am Schlüssel ein Magnet angeordnet ist, der in Wechselwirkung mit einem oder mehreren im Zylinderkern angeordneten Magneten bringbar ist, der seinerseits mit mindestens einem dem Magneten im Zylinderkern in Einführrichtung des Schlüssels in den Schlüsselkanal nachgeordneten Sperrelement zusammenwirkt,
wobei die Magnetanordnung vom Schlüssel, wenn dieser in den Schlüsselkanal eingeführt wird, und / oder Zylinderkern dem Sperrelement so vorgelagert ist, dass die Wechselwirkung der Magnetfelder vor dem Auslösen oder der Abfrage des Sperrelementes wirksam wird.This object is achieved according to the invention in a lock cylinder to be actuated with a key, with a cylinder core rotatably mounted in the cylinder housing, which has a keyway for inserting a key and wherein in the cylinder core as well as the cylinder housing together and with the key cooperating core - and Housing tumblers are provided, characterized in that a magnet is arranged in or on the key, which is engageable with one or more magnets arranged in the cylinder core, which in turn interacts with at least one downstream of the magnet in the cylinder core in the insertion direction of the key in the key channel blocking element,
wherein the magnet assembly of the key, when it is inserted into the keyway, and / or cylinder core is preceded by the blocking element so that the interaction of the magnetic fields before the triggering or interrogation of the blocking element is effective.

Insbesondere gelöst wird diese Aufgabe erfindungsgemäß mit einem mit einem Schlüssel zu betätigenden Schließzylinder, mit einem im Zylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zum Einführen eines Schlüssels aufweist und wobei im Zylinderkern wie auch dem Zylindergehäuse miteinander und mit dem Schlüssel zusammenwirkende Kern - und Gehäusezuhaltungen vorgesehen sind,
dadurch, dass mindestens ein zusätzlicher Sperrstift vorgesehen ist, der in einer Sperrstellung in den Schlüsselkanal hineinragt und dadurch das vollständige Einführen des Schlüssels verhindert und der durch ein im Schlüssel angeordnetes Merkmal in eine den Schlüsselkanal freigebende Freigabestellung bewegbar ist.In particular, this object is achieved according to the invention with a cylinder to be operated with a key lock cylinder, with a cylinder housing rotatably mounted in the cylinder core, which has a keyway for inserting a key and wherein in the cylinder core as well as the cylinder housing together and with the key cooperating core - and housing tumblers provided are,
in that at least one additional locking pin is provided, which projects into a locking position in the key channel and thereby prevents the complete insertion of the key and which is movable by a key arranged in the key feature in a release key release position.

Gemäß der Erfindung ist ein zusätzlicher Sperrstift im Zylinderkern angeordnet, der so in den Schlüsselkanal hineinragt, dass ein Schlüssel nur soweit in den Schlüsselkanal einführbar ist, bis er an den Sperrstift anschlägt.According to the invention, an additional locking pin is arranged in the cylinder core, which projects into the keyway so that a key is only as far inserted into the keyway until it abuts against the locking pin.

Da diese Stellung keinem vollständigen Einführen entspricht, also der Schlüssel nicht an dem Sperrstift vorbei in seine Endstellung geschoben werden kann, lässt sich kein Schließvorgang ausführen.Since this position does not correspond to a complete insertion, so the key can not be pushed past the locking pin in its end position, no closing operation can be performed.

Das Merkmal im Schlüssel kann ein Magnet sein, der mit anderen Magneten in Wirkverbindung bringbar ist.The feature in the key may be a magnet that is operably engageable with other magnets.

Diese Ausbildung des Sperrstiftes hat nichts mit der Ausbildung eines Zuhaltungsstiftes zu tun, der beispielsweise durch eine Magnetanordnung in sein Abgleichlage an der Trennebene Zylinderkern/Schließzylindergehäuse gedrückt wird, weil hierzu das vollständige Einführen des Schlüssels notwendig ist.This design of the locking pin has nothing to do with the formation of a tumbler pin, which is pressed for example by a magnet assembly in its adjustment position on the parting plane cylinder core / lock cylinder housing, because this is the complete insertion of the key is necessary.

Damit die Sperrung des Schlüsselkanals beibehalten werden kann, ist nach einer Ausführung der Erfindung vorgesehen, dass auf den zusätzlichen Sperrstift eine Magnetkraft einwirkt, die den Sperrstift in den Schlüsselkanal hineinzieht.Thus, the blocking of the keyway can be maintained, according to an embodiment of the invention, that acts on the additional locking pin, a magnetic force that pulls the locking pin into the keyway.

Dies kann durch einen im Zylinderkern oder Zylindergehäuse positionierten Magneten erreicht werden, dessen Polung einem am Sperrstift vorgesehenen Magneten ungleich ist.This can be achieved by a magnet positioned in the cylinder core or cylinder housing whose polarity is unequal to a magnet provided on the blocking pin.

Ebenfalls mit einem Magneten, und zwar in seinem Bereich nahe oder in der Schlüsselspitze, versehen ist der Schlüssel. Dieser Magnet ist nun so ausgerichtet, dass er gleichpolig zu der Polung des Magneten am Sperrstiftes wirkt.Also provided with a magnet, in its area near or in the key tip, is the key. This magnet is now aligned so that it acts gleichpolig to the polarity of the magnet on the locking pin.

Das Magnetfeld des Magneten im bzw. am Schlüssel, sollte so ausgebildet sein, dass es der Einführrichtung des Schlüssel beim Einführen in den Schlüsselkanal vorauseilt.The magnetic field of the magnet in or on the key should be designed so that it precedes the insertion direction of the key during insertion into the keyway.

Aufgrund der unterschiedlichen Polungen wird durch den sich beim Einführen dem Sperrstift nähernden Schlüssel das Magnetfeld des im Zylinderkern oder Zylindergehäuse angeordneten Magneten überlagert, der Sperrstift abgestoßen und aus dem Schlüsselkanal entfernt, so dass der Schlüssel weiter in seine Schließposition geschoben oder eingeführt werden kann.Due to the different polarities is superimposed by the magnet in the cylinder core or cylinder housing arranged magnet during insertion of the locking pin, the locking pin repelled and removed from the keyway, so that the key can be pushed or introduced into its closed position.

Vorzugsweise handelt es sich bei den Magneten um Permanentmagnete, jedoch sind auch Elektromagneten oder Kombinationen beider Magnetarten anwendbar.Preferably, the magnets are permanent magnets, but also electromagnets or combinations of both types of magnets are applicable.

Nach einer Ausführung der Erfindung ist der Sperrstift L-förmig ausgebildet, wobei der vom Sperrstift ausgehende Arm, der nicht in den Schlüsselkanal hineinragt muss, einen Magneten trägt, der - in der Einführrichtung des Schlüssels - dem Sperrstift vorgelagert ist.According to one embodiment of the invention, the locking pin is L-shaped, wherein the outgoing of the locking pin arm, which does not protrude into the keyway, carries a magnet which - is preceded - in the direction of insertion of the key - the locking pin.

Auf diese Weise wird die vorher beschriebene Verschiebung oder das Abstoßen des Sperrstiftes in Bezug auf den Schlüsselkanal unmittelbar vor dem Auftreffen der Schlüsselspitze auf den Sperrstiftstift erfolgen, so dass dieser für das vollständige Einführen des Schlüssels frei gegeben wird.In this way, the previously described displacement or repulsion of the locking pin with respect to the keyway will occur just prior to the impact of the key tip on the locking pin so that it will be released for complete insertion of the key.

Zur Erfindung gehört nicht nur ein entsprechend ausgebildeter Schließzylinder, sondern auch der mit einem solchen Merkmal versehene Schlüssel, welches in der Lage ist, mit dem Schließzylinder im Sinne der auf diesen gerichteten Ansprüche zusammen zu wirken.The invention includes not only a suitably trained lock cylinder, but also the key provided with such a feature, which is able to cooperate with the lock cylinder in the sense of directed to these claims together.

Die Erfindung soll nachfolgend an Ausführungsbeispielen mit Bezug auf die Zeichnungen beschrieben werden.The invention is based on embodiments with reference to the drawings to be discribed.

Dabei zeigt:

  • Fig. 1, 2 eine schematische Schnittdarstellung durch den Zylinderkern mit eingeführtem Schlüssel bei geschlossener und offener Position des Sperrstiftes in magnetischer Ausführung
  • Fig. 3, 4 eine abgewandelte magnetische Ausführung mit entsprechenden Positionen des Sperrstiftes
  • Fig. 5, 6 eine mechanische Ausführung, wiederum in beiden Positionen des Sperrstiftes
Showing:
  • Fig. 1 . 2 a schematic sectional view through the cylinder core with inserted key in the closed and open position of the locking pin in a magnetic design
  • Fig. 3 . 4 a modified magnetic design with corresponding positions of the locking pin
  • Fig. 5 . 6 a mechanical version, again in both positions of the locking pin

Bei allen dargestellten Ausführungen sind gleiche Teile mit den gleichen Bezugszeichen versehen.In all the illustrated embodiments, the same parts are provided with the same reference numerals.

So ist mit 1 der Zylinderkern bezeichnet, der in bekannter Weise in einem Schließzylindergehäuse drehbar gelagert ist. Auf die Darstellung dieses Gehäuses wurde hier verzichtet.Thus, denoted by 1 of the cylinder core, which is rotatably mounted in a known manner in a lock cylinder housing. On the presentation of this case was omitted here.

In dem Zylinderkern 1 befindet sich der Schlüsselkanal 8, in den der Schlüssel 2 einführbar ist.In the cylinder core 1 is the key channel 8, in which the key 2 is inserted.

Auch hierbei wurde die Darstellung vereinfacht, d. h. die üblichen Zuhaltungen 12 wurden nur angedeutet.Again, the presentation has been simplified, d. H. the usual tumblers 12 were only hinted at.

Der Kern der Erfindung liegt in dem Einsatz eines Sperrstiftes 5, der im Normalzustand - wenn sich kein Schlüssel in seinem Verschiebungsbereich oder Hubbereich befindet - soweit in den Schlüsselkanal 8 hineinragt, dass ein teilweise eingeführter Schlüssel an seinem weiteren Vorschub durch den Sperrstift gehindert wird. Bezogen auf den Längsschnitt durch den Zylinderkern ist der Sperrstift radial verschiebbar.The essence of the invention lies in the use of a locking pin 5, which in the normal state - if there is no key in its displacement range or stroke range - so far projects into the keyway 8 that a partially inserted key is prevented from further advancing by the locking pin. Based on the longitudinal section through the cylinder core of the locking pin is radially displaceable.

Bei der Ausführung nach den Figuren 1 und 2 , ist der Sperrstift an seinem einen Ende von einem ringförmigen Magneten 6 umgeben, der sich mit dem Sperrstift in einer entsprechenden Bohrung des Zylinderkernes bewegen kann. Dem freien Ende des Sperrstiftes 5 im Kern gegenüberliegend ist ein weiterer Magnet 4 angeordnet, wobei die Polung der Magneten 4 und 6 so gewählt ist, dass zwischen beiden eine Anziehungskraft wirkt, d. h. der Sperrstift 5 wird mit seinem Magneten 6 vom Magneten 4 angezogen, so dass der Sperrstift 5 in seiner Position gehalten wird, die den Schlüsselkanal blockiert oder verschließt.In the execution of the FIGS. 1 and 2 , the locking pin is surrounded at its one end by an annular magnet 6 which can move with the locking pin in a corresponding bore of the cylinder core. The free end of the locking pin 5 in the core opposite another magnet 4 is arranged, wherein the Polarity of the magnets 4 and 6 is chosen so that an attraction force acts between them, ie the locking pin 5 is attracted with its magnet 6 from the magnet 4, so that the locking pin 5 is held in its position, which blocks or closes the keyway.

Die Spitze oder der vordere Bereich des Schlüssels 2 ist ebenfalls mit einem Magneten versehen, der mit 3 bezeichnet ist.The tip or the front portion of the key 2 is also provided with a magnet, which is designated 3.

Die Polung dieses Magneten 3 ist nun so, dass der mit dem Sperrstift 5 bewegliche Magnet 6 abgestoßen wird. Damit wird der Sperrstift in seine Bohrung zurück gedrückt und gibt den Schlüsselkanal 8 frei, so dass der Schlüssel 2 weiter in diesen eingeführt werden kann, bis er seine Endstellung erreicht, in der ein Schließvorgang ausführbar ist.The polarity of this magnet 3 is now such that the magnet 6 which is movable with the locking pin 5 is repelled. Thus, the locking pin is pushed back into its bore and releases the key channel 8, so that the key 2 can be further inserted into this until it reaches its end position in which a closing operation is executable.

Diese Wirkungsweise ist vergleichbar mit der bei der Ausführung nach den Figuren 3 und 4. Der Unterschied liegt nur in der Ausbildung oder Gestaltung des Sperrstiftes 5.This mode of action is comparable to that in the execution of the Figures 3 and 4 , The difference lies only in the design or design of the locking pin. 5

Im Gegensatz zu dem ringförmigen Magneten 6 ist bei dieser Ausführung der Sperrstift mit einem L-förmigen Arm 7 versehen, der den Magneten 6' trägt.In contrast to the annular magnet 6, in this embodiment, the locking pin is provided with an L-shaped arm 7, which carries the magnet 6 '.

Dieser Magnet ist dem Sperrstift damit vorgelagert, d. h. der Schlüssel nähert sich mit seinem Magneten 3 erst dem Magneten 6' und dann dem Sperrstift 5.This magnet is upstream of the locking pin, d. H. The key approaches with its magnet 3 only the magnet 6 'and then the locking pin. 5

Unter der Wirkung der Gleichausrichtung der Polung der Magneten 3 und 6' wird der Sperrstift 5 bewegt (Figur 4) und gibt damit den Schlüsselkanal 8 frei.Under the effect of the alignment of the polarity of the magnets 3 and 6 ', the locking pin 5 is moved ( FIG. 4 ) and thus releases the key channel 8.

Während bei den Ausführungen nach den Figuren 1-4 das Merkmal im Schlüssel ein Magnet 3 ist, ist bei der Ausführung nach den Figuren 5 und 6 eine rein mechanische Variante dargestellt, wobei das Merkmal hier aus einem beweglichen Vorsprung 3' , beispielsweise einer Kugel besteht.While in the versions after the Figures 1-4 the feature in the key is a magnet 3, is in the execution of the Figures 5 and 6 a purely mechanical variant shown, the feature here consists of a movable projection 3 ', for example a ball.

In der in der Figur 5 dargestellten Position verschließt der Sperrstift 5 den Schlüsselkanal 8, so dass der Schlüssel 2 nur bis nahe an den Sperrstift 5 heran eingeführt werden kann. Das besondere Merkmal des Schlüssels ist hierbei der Vorsprung bzw. die Kugel 3'. Diese ist wiederum im vorderen Bereich des Schlüssels angeordnet, wobei der Abstand zur Schlüsselspitze so besessen ist, dass das Merkmal am Schlüssel seine Wirkung auf die Sperranordnung entfalten kann, bevor diese Schlüsselspitze den Sperrstift berührt.In the in the FIG. 5 illustrated position of the locking pin 5 closes the key channel 8, so that the key 2 can be introduced only close to the locking pin 5 zoom. The special feature of the key here is the projection or the ball 3 '. This is in turn located in the front of the key, the distance to the key tip is so obsessed that the feature on the key can exert its effect on the locking arrangement before this key tip touches the locking pin.

Der Sperrstift 5 steht in Eingriff mit einem federbelasteten (Feder 10) Schwenkhebel oder - teil 9 und weist einen Vorsprung 11 auf, der mit dem Merkmal am Schlüssel, also dem Vorsprung 3' oder der Kugel in Kontakt kommt, wenn der Schlüssel entsprechend weit eingeführt wird. Dies zeigt die Figur 6, aus der auch ersichtlich ist, dass der Kontakt zwischen dem Merkmal am Schlüssel und dem Schwenkhebel dazu führt, dass dieser - in diesem Ausführungsbeispiel - radial verschwenkt wird, den Sperrstift mitnimmt und dadurch diesen aus dem Schlüsselkanal herausbewegt. Damit kann der Schlüssel dann bis in seine Endstellung eingeführt werden, in der ein Schließvorgang ausführbar ist.The locking pin 5 is in engagement with a spring-loaded (spring 10) pivot lever or - part 9 and has a projection 11, which with the feature on the key, so the Projection 3 'or the ball comes into contact when the key is inserted accordingly far. This shows the FIG. 6 , from which it is also apparent that the contact between the feature on the key and the pivoting lever causes it - is pivoted radially in this embodiment - entrains the locking pin and thereby moves it out of the keyway. Thus, the key can then be inserted into its end position, in which a closing operation is executed.

Der erfindungsgemäß vorgesehene zusätzliche Sperrstift kann - wie bei dem vorstehend beschriebenen Ausführungsbeispiel - quer zum Schlüsselkanal verschiebbar sein.The inventively provided additional locking pin can - as in the embodiment described above - be displaceable transversely to the key channel.

Allerdings ist auch eine andere Verschiebungsrichtung möglich, vorausgesetzt, die Anordnung des Sperrstiftes ist so, dass in seiner Sperrstellung der vollständige Einschub eines Schlüssels in den Schlüsselkanal verhindert wird.However, a different direction of displacement is possible, provided that the arrangement of the locking pin is such that in its locked position the complete insertion of a key is prevented in the keyway.
