Description

Die Erfindung betrifft einen Schließzylinder gemäß dem Oberbegriff des Patentanspruchs 1 zum Verschließen einer Klappe an einem Kraftfahrzeug wie einer Tür, einer Heckklappe oder dergleichen. Der Schließzylinder weist einen Zylinderkern auf, der in einem Zylindergehäuse drehbar aufgenommen ist. Im Zylinderkern ist mindestens ein Sperrorgan vorgesehen, das in einer Sperrposition eine Drehung des Zylinderkerns im Zylindergehäuse verhindert und in einer Freigabeposition eine Drehung im Schließzylinder freigibt. Durch den Zylinderkern erstreckt sich ein Schlüsselkanal, in dem ein Schlüssel einführbar ist und mit dem das Sperrorgan zwischen der Sperrposition und der Freigabeposition bewegbar ist.The invention relates to a lock cylinder according to the preamble of claim 1 for closing a flap on a motor vehicle such as a door, a tailgate or the like. The lock cylinder has a cylinder core, which is rotatably received in a cylinder housing. In the cylinder core at least one locking member is provided which prevents rotation of the cylinder core in the cylinder housing in a locking position and releases a rotation in the lock cylinder in a release position. Through the cylinder core extends a key channel in which a key is inserted and with which the locking member between the locking position and the release position is movable.

Derartige Schließzylinder finden für die Türen, die Heckklappe oder weiteren Klappen, wie dem Handschuhfach oder dergleichen, in einem Kraftfahrzeug Anwendung. Die gewöhnliche Bedienung eines derartigen Schließzylinders erfolgt mit einem passenden Schlüssel, wobei bei modernen Schließsystemen von Kraftfahrzeugen, die zentral verriegelnde, elektrische Schließsysteme betreffen, auch heute noch konventionelle Schließzylinder vorgesehen sind, um eine Notöffnung wenigstens einer Klappe des Kraftfahrzeugs zu ermöglichen.Such lock cylinders are used for the doors, the tailgate or other flaps, such as the glove compartment or the like, in a motor vehicle application. The usual operation of such a lock cylinder takes place with a matching key, which in modern locking systems of motor vehicles, which concern centrally locking, electrical locking systems, even today conventional lock cylinders are provided to allow emergency opening of at least one flap of the motor vehicle.

Im Zylinderkern sind mehrere Sperrorgane aufgenommen, die im Fachsprachgebrauch häufig als Zuhaltungen oder Plattenzuhaltungen bezeichnet werden. Diese Sperrorgane sind in Sperrorganaufnahmen im Zylinderkern aufgenommen und durch eine Druckfeder in einer quer zum Schlüsselkanal verlaufenden Richtung beweglich vorgespannt. Ist der Schlüssel nicht in den Schlüsselkanal eingeführt, besitzen die Sperrorgane eine Sperrposition, in der ein zungenartiger Fortsatz der Sperrorgane in eine jeweilige Nut im Zylindergehäuse hineinragt. Dadurch ist eine Drehbewegung des Zylinderkerns innerhalb des Zylindergehäuses verhindert und die Schließfunktionsteile der Klappe des Kraftfahrzeugs können über einen Mitnehmer, der sich beispielsweise an den Schließzylinder rückseitig anschließt, nicht betätigt werden. Erst bei Einführen des passenden Schlüssels mit einem Schlüsselbart in den Schlüsselkanal wird durch eine Wirkverbindung zwischen dem Schlüsselbart und den Sperrorganen eine jeweilige Freigabeposition der Sperrorgane erreicht, die eine Rotation des Zylinderkerns innerhalb des Zylindergehäuses ermöglichen.In the cylinder core several locking elements are included, which are often referred to in technical language as tumblers or Plattenzuhaltungen. These locking members are received in locking organ receptacles in the cylinder core and biased by a compression spring in a direction transverse to the key channel direction movable. If the key is not inserted into the keyway, the locking members have a locking position in which a tongue-like extension of the locking members protrudes into a respective groove in the cylinder housing. As a result, a rotational movement of the cylinder core is prevented within the cylinder housing and the closing functional parts of the flap of the motor vehicle can not be actuated by a driver, for example, the back of the lock cylinder. Only when inserting the matching key with a key bit in the keyway a respective release position of the locking members is achieved by an operative connection between the key bit and the locking members, which allow rotation of the cylinder core within the cylinder housing.

Die Sicherheit gegen ein unbefugtes Öffnen der Klappe des Kraftfahrzeugs ist insofern begrenzt, als dass durch das Eindringen eines Fremdkörpers in den Zylinderkern unter Anwendung von Gewalt ein Verdrehen des Zylinderkerns im Zylindergehäuse möglich ist. Wird der Schlüsselkanal z. B. mittels eines Bohrwerkzeugs aufgebohrt, können die Sperrorgane auch ohne einen zugeordneten Schlüssel in die Freigabeposition überführt werden, so dass sich der Zylinderkern im Zylindergehäuse drehen lässt. Um das Eindringen des Fremdkörpers in den Schließzylinder zu verhindern, sind zwar Verstärkungen im Außenbereich der Klappe des Kraftfahrzeugs bekannt, jedoch bieten diese Verstärkungen keinen wirksamen, nachhaltigen Schutz gegen ein unbefugtes Öffnen der Klappe des Kraftfahrzeugs.The security against unauthorized opening of the flap of the motor vehicle is limited insofar as that by the penetration of a foreign body in the cylinder core using force twisting of the cylinder core in the cylinder housing is possible. If the key channel z. B. drilled by means of a drilling tool, the locking members can be transferred without an associated key in the release position, so that the cylinder core can rotate in the cylinder housing. In order to prevent the penetration of the foreign body in the lock cylinder, although reinforcements in the outer region of the flap of the motor vehicle are known, however, these reinforcements do not provide effective, lasting protection against unauthorized opening of the flap of the motor vehicle.

Aus der DE 41 22 414 C1 ist ein gattungsbildender Schließzylinder zum Verschließen einer Klappe an einem Kraftfahrzeug bekannt. Der Zylinderkern ist im Zylindergehäuse angeordnet, wobei der Zylinderkern bei abgezogenem Schlüssel über federbelastete Sperrorgane mit dem Zylindergehäuse verriegelbar ist, wobei das Zylindergehäuse wiederum in einer weiteren Aufnahme drehbar gelagert und im Überlastfall durch eine sich selbsttätig parallel zur Drehachse des Zylinderkerns ausrückenden Überlastsperre in Form eines Rastgesperres drehfixiert ist. Dabei ist ein axialfest im Zylindergehäuse gelagertes Drehglied vorgesehen, das auf die Schließfunktionsteile der Klappe des Kraftfahrzeugs einwirkt und mit einer Kupplung zwischen dem Drehglied und dem Schließzylinder, die sich im Überlastfall mit der Ausrückbewegung der Überlastsperre auskuppelt, vorgesehen ist. Dadurch wird erreicht, dass trotz des Eindringens eines Fremdkörpers in den Schließzylinder eine Betätigung des Mitnehmers nicht möglich ist.From the DE 41 22 414 C1 is a generic lock cylinder for closing a flap on a motor vehicle known. The cylinder core is arranged in the cylinder housing, wherein the cylinder core with spring removed via spring-loaded Locking elements can be locked to the cylinder housing, wherein the cylinder housing in turn rotatably mounted in a further receptacle and rotationally fixed in case of overload by a self-acting parallel to the axis of rotation of the cylinder core overload lock in the form of a Rastgesperres. In this case, a rotationally fixed in the cylinder housing mounted rotary member is provided, which acts on the closing functional parts of the flap of the motor vehicle and with a coupling between the rotary member and the lock cylinder disengages in case of overload with the disengagement of the overload lock is provided. This ensures that despite the penetration of a foreign body in the lock cylinder actuation of the driver is not possible.

Jedoch ist ein derartiger Schließzylinder aus einer Vielzahl von Einzelteilen ausgebildet und aufwendig ausgestaltet und die separate Aufnahme für das Zylindergehäuse erfordert weiteren Bauraum, der nicht grundsätzlich zur Verfügung steht. Ferner kann ein gewaltsam in den Schließzylinder eingebrachter Gegenstand als Hebel verwendet werden, so dass diese Hebelwirkung durch die hier dargestellte Lösung nicht verhindert werden kann, und der Schließzylinder kann aus seiner Aufnahme durch die Hebelwirkung heraus gebrochen werden.However, such a lock cylinder is formed from a variety of items and designed consuming and the separate receptacle for the cylinder housing requires more space, which is not available in principle. Further, a forcefully introduced into the lock cylinder object can be used as a lever, so that this leverage can not be prevented by the solution shown here, and the lock cylinder can be broken from its inclusion by the leverage out.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Schließzylinder zu schaffen, der die Sicherheit gegen ein unbefugtes Öffnen einer Klappe eines Kraftfahrzeugs, insbesondere durch einen Aufbohrversuch, weiter erhöht.It is therefore an object of the present invention to provide a lock cylinder, which further increases security against unauthorized opening of a flap of a motor vehicle, in particular by a Aufbohrversuch.

Diese Aufgabe wird ausgehend von einem Schließzylinder zum Verschließen einer Klappe an einem Kraftfahrzeug gemäß dem Oberbegriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved starting from a lock cylinder for closing a flap on a motor vehicle according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die technische Lehre ein, dass wenigstens ein Sicherheitselement aus einem Material hoher Härte im Bereich des Schlüsselkanals derart angeordnet ist, dass durch das Sicherheitselement ein Eindringen eines Fremdkörpers in den Schließzylinder erschwert ist. Der Bereich des Schlüsselkanals betrifft vorliegend sowohl den Schlüsselkanal selbst als auch den umgebenden Bereich um den Schlüsselkanal herum.The invention includes the technical teaching that at least one security element made of a material of high hardness in the region of the keyway is arranged such that penetration of a foreign body into the lock cylinder is made more difficult by the security element. The area of the key channel relates in the present case to both the key channel itself and the surrounding area around the key channel.

Um einen Schließzylinder unbefugt zu betätigen, wird als Fremdkörper häufig ein Bohrwerkzeug verwendet. Ist ein Sicherheitselement aus einem Material hoher Härte im Bereich des Schlüsselkanals und/oder um den Schlüsselkanal herum angeordnet, stößt das Bohrwerkzeug beim Eindringen in den Schließzylinder auf das Sicherheitselement. Dadurch ist das weitere Eindringen des Fremdkörpers in den Schließzylinder erschwert oder sogar verhindert. Folglich können die Sperrorgane, die sich hinter dem Sicherheitselement innerhalb des Zylinderkerns befinden, durch das Bohrwerkzeug nicht beschädigt werden. Im Ergebnis wird ein Überführen der genannten Sperrorgane von der Sperrposition in die Freigabeposition durch das Bohrwerkzeug und gegebenenfalls einer anschließenden Manipulation nicht ermöglicht.To operate a lock cylinder without authorization, a drilling tool is often used as a foreign body. If a security element made of a material of high hardness is arranged in the region of the keyway and / or around the keyway, the drilling tool encounters the security element upon penetration into the lock cylinder. As a result, the further penetration of the foreign body in the lock cylinder is difficult or even prevented. Consequently, the locking members, which are located behind the security element within the cylinder core, can not be damaged by the drilling tool. As a result, a transfer of the said locking members from the locking position to the release position by the drilling tool and optionally a subsequent manipulation is not possible.

Ist der Fremdkörper als Hebelelement ausgeführt, um den Zylinderkern innerhalb des Zylindergehäuses aus diesem heraus zu hebeln, kann das Hebelelement nicht hinreichend tief in den Schlüsselkanal eingebracht werden, so dass auch eine derartige Manipulation durch eine Hebeleinwirkung durch das erfindungsgemäße Sicherheitselement unterbunden ist. Durch das erschwerte Eindringen des Fremdkörpers in den Schließzylinder verlängern sich die Aufbruchzeiten des Schließsystems zum unbefugten Öffnen der Klappe des Kraftfahrzeugs derart, dass das zugeordnete Kraftfahrzeug mit dem erfindungsgemäßen Schließzylinder für einen Diebstahl unattraktiv wird.If the foreign body designed as a lever element to pry the cylinder core within the cylinder housing out of this, the lever element can not be sufficiently deep introduced into the keyway, so that even such manipulation is prevented by a lever action by the security element according to the invention. Due to the difficult penetration of the foreign body in the lock cylinder extend the break-up times of the locking system for unauthorized opening of the flap of the motor vehicle such that the associated motor vehicle is unattractive with the lock cylinder according to the invention for theft.

Zur Aufnahme des erfindungsgemäßen Sicherheitselementes besitzt der Zylinderkern wenigstens eine Aufnahmetasche, in die das Sicherheitselement bei Montage des Schließzylinders eingesetzt werden kann. Dabei kann nur eine oder sogar mehrere Aufnahmetaschen für je ein Sicherheitselement innerhalb des Zylinderkerns vorgesehen sein, wobei bei Anwendung mehrerer Sicherheitselemente die Sicherheit des Schließzylinders weiter erhöht wird. Der Zylinderkern erstreckt sich entlang des Schlüsselkanals und besitzt eine Mantelfläche, so dass die Aufnahmetaschen eine im Wesentlichen U-förmige Gestalt besitzen, dessen Öffnung in Richtung zur Mantelfläche des Zylinderkerns weist. Über diese Öffnung in der Mantelfläche kann das Sicherheitselement in die Aufnahmetasche eingesetzt werden.To accommodate the security element according to the invention, the cylinder core has at least one receiving pocket into which the security element can be inserted during assembly of the lock cylinder. In this case, only one or even more receiving pockets can be provided for each one security element within the cylinder core, wherein the safety of the lock cylinder is further increased when using a plurality of security elements. The cylinder core extends along the keyway and has a lateral surface, so that the receiving pockets have a substantially U-shaped form, the opening points in the direction of the lateral surface of the cylinder core. About this opening in the lateral surface, the security element can be inserted into the receiving pocket.

Ferner ist vorgesehen, dass die Sperrorgane in Sperrorganaufnahmen aufgenommen sind, die ebenfalls taschenartig ausgeformt sind. Die zumindest eine Aufnahmetasche innerhalb des Zylinderkerns kann dabei insbesondere parallel zwischen zumindest zwei Sperrorganaufnahmen im Zylinderkern eingebracht sein. Sind mehrere Aufnahmetaschen zur Anordnung mehrerer Sicherheitselemente innerhalb des Zylinderkerns vorgesehen, können die Aufnahmetaschen beispielsweise abwechselnd mit den Sperrorganaufnahmen entlang des Schlüsselkanals angeordnet sein.It is further provided that the locking members are received in locking organ recordings, which are also formed pocket-like. The at least one storage bag inside The cylinder core can be introduced in particular parallel between at least two locking organ recordings in the cylinder core. If a plurality of receiving pockets are provided for arranging a plurality of security elements within the cylinder core, the receiving pockets can be arranged, for example, alternately with the blocking device receptacles along the keyway.

Der Schließzylinder besitzt einen Kopfbereich, über den der Schlüssel in den Schlüsselkanal einführbar ist, so dass der Kopfbereich im eingebauten Zustand des Schließzylinders zur Außenseite der Klappe des Kraftfahrzeugs weist. Die wenigstens eine Aufnahmetasche zur Aufnahme des Sicherheitselementes kann dabei im Kopfbereich oder im Abschnitt zwischen dem Kopfbereich und den Sperrorganaufnahmen angeordnet werden. Je näher das Sicherheitselement in Richtung zum Kopfbereich des Schließzylinders angeordnet ist, desto geringer ist die Tiefe, in die der Fremdkörper in den Zylinderkern gewaltsam eingebracht werden kann, so dass sich dadurch die Sicherheit gegen ein unbefugtes Öffnen der Klappe des Kraftfahrzeugs weiter erhöht. Der Grund für die erhöhte Sicherheit liegt darin, dass die sich hinter dem Sicherheitselement befindlichen Sperrorgane nicht durch den eindringenden Fremdkörper beschädigt werden können, da das Sicherheitselement eine Art Sicherheitsschild bildet und somit ein weiteres Eindringen verhindert. Besonders vorteilhaft ist es, wenn ein erstes Sicherheitselement im Kopfbereich des Schließzylinders eingebracht ist, wobei ein oder mehrere weitere Sicherheitselemente zwischen den jeweiligen Sperrorganaufnahmen vorgesehen sind.The lock cylinder has a head region, via which the key can be introduced into the keyway, so that the head region points in the installed state of the lock cylinder to the outside of the flap of the motor vehicle. The at least one receiving pocket for receiving the security element can be arranged in the head region or in the section between the head region and the barrier organ mountings. The closer the security element is arranged in the direction of the head region of the lock cylinder, the lower the depth, in which the foreign body can be forcibly introduced into the cylinder core, thereby further increasing the security against unauthorized opening of the flap of the motor vehicle. The reason for the increased security is that the locking elements located behind the security element can not be damaged by the penetrating foreign body, since the security element forms a kind of security shield and thus prevents further penetration. It is particularly advantageous if a first security element is introduced in the head region of the lock cylinder, wherein one or more further security elements are provided between the respective lock organ receivers.

Nach einer weiteren Verbesserung des erfindungsgemäßen Schließzylinders ist das Sicherheitselement in Gestalt einer Scheibe ausgeführt. Damit entspricht die Außenkontur des Sicherheitselementes der Außenkontur des Zylinderkerns. Der Durchmesser der Scheibe kann entsprechend geringer ausgeführt sein, als der Durchmesser des Zylinderkerns. Folglich kann der Durchmesser der Aufnahmetasche dem Durchmesser der Scheibe entsprechen. Die Scheibe kann dabei eine Dicke von 0,5 mm bis 5 mm, bevorzugt von 1 mm bis 3,5 mm und besonders bevorzugt von 2 mm besitzen. Um eine hohe Härte der Scheibe zu erreichen, kann diese aus einem Hartmetall, einem legierten Werkzeugstahl, einem sonstigen hoch legierten Stahl oder sogar aus einer Keramik ausgebildet sein.After a further improvement of the lock cylinder according to the invention, the security element is designed in the form of a disc. Thus, the outer contour of the security element corresponds to the outer contour of the cylinder core. The diameter of the disc can be made correspondingly smaller than the diameter of the cylinder core. Consequently, the diameter of the receiving pocket may correspond to the diameter of the disc. The disk may have a thickness of 0.5 mm to 5 mm, preferably from 1 mm to 3.5 mm and particularly preferably 2 mm. In order to achieve a high hardness of the disc, this may be formed of a hard metal, an alloyed tool steel, another high alloy steel or even a ceramic.

Um die Drehposition der Scheibe innerhalb der Aufnahmetasche zu sichern, kann eine Sperrnase vorgesehen sein, die in den Aufnahmebereich der Aufnahmetasche hineinragt, wobei die Scheibe z. B. eine komplementär ausgeführte Sperrnut besitzt, in die die Sperrnase bei eingesetzter Scheibe in der Aufnahmetasche eingreift. Damit wird eine Sollbruchstelle geschaffen, die nach einem Bruch ein Verdrehen der Scheibe in der Aufnahmetasche ermöglicht.In order to secure the rotational position of the disc within the receiving pocket, a locking nose may be provided which projects into the receiving area of the receiving pocket, wherein the disc z. B. has a complementary executed locking groove into which the locking lug engages inserted disc in the receiving pocket. Thus, a predetermined breaking point is created, which allows for a rotation of a twisting of the disc in the receiving pocket.

Die Scheibe besitzt eine Öffnung, die derart bestimmt ist, dass der Schlüssel durch das Sicherheitselement hindurch führbar ist. Die Sperrorgane besitzen ebenfalls eine Öffnung, so dass sich die Öffnungen in den Sicherheitselementen und die Öffnungen in den Sperrorganen entlang des Schlüsselkanals hinweg erstrecken und der Schlüssel in den Schlüsselkanal eingeführt werden kann. Die Öffnungen in den Sicherheitselementen sind an den Querschnitt des Schlüsselkanals angepasst und nicht viel größer als dieser ausgeführt.The disc has an opening which is determined such that the key can be guided through the security element. The locking members also have an opening so that the openings in the security elements and the openings in the locking members extend along the keyway and the key can be inserted into the keyway. The openings in the security elements are adapted to the cross section of the keyway and not much larger than this executed.

Folglich besitzen die Öffnungen in den Sicherheitselementen eine längliche Erstreckung, die in der Position festgelegt ist, so dass der Schlüsselkanal nicht durch die Scheiben unterbrochen ist. Im Ergebnis kann die Erstreckung der Öffnung innerhalb des Sicherheitselementes durch den Eingriff der Sperrnase in die Sperrnut innerhalb der Aufnahmetasche sichergestellt werden. Die Außenkontur der Scheibe ist vorzugsweise rund ausgeführt, wobei ebenfalls eine eckige, insbesondere einen Vielkant aufweisende Kontur möglich ist.Consequently, the openings in the security elements have an elongated extension which is fixed in position, so that the keyway is not interrupted by the discs. As a result, the extent of the opening within the security element can be ensured by the engagement of the locking lug in the locking groove within the receiving pocket. The outer contour of the disc is preferably carried out round, wherein also an angular, in particular a polygon-having contour is possible.

Es ist von besonderem Vorteil, wenn die Festigkeit der Sperrnase derart bestimmt ist, dass diese bei Aufbringen eines vorbestimmten Drehmomentes z. B. durch einen Bohrer auf das Sicherheitselement abschert. Wird als Fremdkörper ein Bohrwerkzeug verwendet und gerät das Bohrwerkzeug in Kontakt mit dem Sicherheitselement und insbesondere in Eingriff mit der Öffnung innerhalb des Sicherheitselementes, so kann das Sicherheitselement mit der Drehbewegung des Bohrwerkzeugs mitdrehen. Ein weiteres Eindringen des Bohrwerkzeugs ist damit effektiv verhindert, da der Bohrvorgang durch das Sicherheitselement hindurch nicht fortgesetzt werden kann. Alternativ kann die Sperrnut innerhalb des Sicherheitselementes derart ausgeführt sein, dass das Mitdrehen des Sicherheitselementes beim Angriff durch ein Bohrwerkzeug ebenfalls sichergestellt ist.It is of particular advantage if the strength of the locking lug is determined such that it is applied when applying a predetermined torque z. B. shears by a drill on the security element. If a drilling tool is used as a foreign body and the drilling tool comes into contact with the security element and in particular in engagement with the opening within the security element, then the security element can rotate with the rotational movement of the drilling tool. Further penetration of the drilling tool is thus effectively prevented, since the drilling process through the security element can not be continued. Alternatively, the locking groove can be embodied within the security element in such a manner that the turning of the security element during engagement by a drilling tool is likewise ensured.

Um die Sicherheit gegen das Eindringen eines Fremdkörpers in den Schlüsselkanal im Zylinderkern weiter zu erhöhen, können auch die Sperrorgane aus einem Hartmetall, einem legierten Werkzeugstahl, einem sonstigen hoch legierten Stahl oder aus einer Keramik ausgebildet sein. Insbesondere kann vorgesehen sein, dass der Zylinderkern mehrere Aufnahmetaschen aufweist, in die jeweils ein oder mehrere Sicherheitselemente in beliebiger Anzahl und in beliebiger Position einsetzbar sind. Dadurch wird erreicht, dass ein Schließzylinder, der einem bestimmten Kraftfahrzeugtyp zugeordnet ist, ein unterschiedliches Sicherheitsverhalten gegen das Eindringen eines Fremdkörpers in den Schließzylinder aufweist. Eine unbefugte Person kann folglich keinen standardisierten Vorgang zum gewaltsamen Öffnen des Schließzylinders, beispielsweise durch ein Aufbohren des Schlüsselkanals durch ein Bohrwerkzeug, anwenden und ausführen.In order to further increase the security against the penetration of a foreign body in the keyway in the cylinder core, the locking members may be formed of a hard metal, an alloyed tool steel, another high alloy steel or a ceramic. In particular, it can be provided that the cylinder core has a plurality of receiving pockets, in each of which one or more security elements in any number and in any position can be used. This ensures that a lock cylinder, which is assigned to a certain type of motor vehicle, has a different safety behavior against the penetration of a foreign body in the lock cylinder. Consequently, an unauthorized person can not apply and execute a standardized operation for forcibly opening the lock cylinder, for example, by drilling the keyway by a boring tool.

Das Hindernis gegen das Eindringen eines Bohrwerkzeugs in den Schlüsselkanal erfolgt durch das Sicherheitselement an unterschiedlichen Positionen, wobei durch die zusätzliche Ausführung der Sperrorgane aus einem Material hoher Härte die Veränderung verschiedener Eindringtiefen eines Bohrwerkzeugs in den Schließzylinder weiter erhöht wird, und sich folglich mehrere Aufbruchzeiten durch mehrere Sicherheitselemente zu verschieden langen Gesamtaufbruchzeiten addieren. Die Anwendung eines standardisierten Aufbruchverfahrens zum gewaltsamen Öffnen des Schließzylinders ist somit wirksam verhindert.The obstacle against the penetration of a drilling tool into the keyway is made by the security element at different positions, the change of different penetration depths of a drilling tool in the lock cylinder is further increased by the additional design of the locking members of a material of high hardness, and thus several break-up times by several Add security elements to different total break times. The application of a standardized break-open method for forcibly opening the lock cylinder is thus effectively prevented.

Um das Sicherheitselement innerhalb der Aufnahmetasche verliersicher anzuordnen, ist ein Verschlusselement vorgesehen. Dieses verschließt die Aufnahmetasche in Richtung zur Öffnung, das heißt in Richtung zur Mantelfläche des Zylinderkerns. Das Verschlusselement kann in der Öffnung der Aufnahmetasche in seiner Verschlussposition neben einer losen Anordnung formschlüssig eingefasst, verkörnt, verklebt, verlötet oder verschweißt werden.In order to arrange the security element captive within the receiving pocket, a closure element is provided. This closes the receiving pocket in the direction of the opening, that is, in the direction of the lateral surface of the cylinder core. The closure element can be framed in the opening of the receiving pocket in its closed position in addition to a loose arrangement form, trimmed, glued, soldered or welded.

Weiterführend kann vorgesehen sein, dass das Verschlusselement eine weitere Sperrnase aufweist, die zum Eingriff in eine weitere Sperrnut im Sicherheitselement ausgebildet ist. Damit wird eine zusätzliche Drehsicherung des Verschlusselementes in der Aufnahmetasche geschaffen, die auch alternativ zur Sperrnase ausgeführt sein kann, die innerhalb der Aufnahmetasche eingebracht ist und in den Aufnahmebereich hineinragt. Das Verschlusselement kann in der Öffnung der Aufnahmetasche derart eingesetzt sein, dass dieses bei Aufbringen eines Drehmomentes auf das Verschlusselement zumindest ein Stück weit aus der Öffnung der Aufnahmetasche herausgedrückt wird, indem die Sperrnut auf der Sperrnase abgleitet.Furthermore, it can be provided that the closure element has a further locking nose, which is designed to engage in a further locking groove in the security element. Thus, an additional rotational security of the closure element is created in the receiving pocket, which can also be designed as an alternative to the locking lug, which is introduced within the receiving pocket and protrudes into the receiving area. The closure element may be inserted in the opening of the receiving pocket such that this is at least a little pushed out of the opening of the receiving pocket by applying a torque to the closure element by the locking groove slides on the locking lug.

Damit weicht das Verschlusselement ein Stück aus seiner Verschlussposition heraus und das scheibenförmige Sicherheitselement kann - beispielsweise durch Mitnahme mittels eines Bohrwerkzeugs - in Drehbewegung versetzt werden.Thus, the closure element gives way a bit out of its closed position and the disc-shaped security element can - for example, by entrainment by means of a drilling tool - are set in rotary motion.

Gemäß einer weiteren Ausführungsform der Anordnung des Sicherheitselementes innerhalb des Schließzylinders kann dieses sogar als Bestandteil eines Sperrorgans ausgebildet sein. Dabei kann das Sicherheitselement als scheibenförmiges Mittelelement im Sperrorgan angeordnet werden, so dass bei Aufbringen eines bestimmten Drehmomentes auf das Sicherheitselement eine Drehbewegung des scheibenförmigen Sicherheitselementes im mittigen Bereich des Sperrorgans erzeugt wird. Damit können die Sperrorgane zweiteilig ausgeführt sein und einen Schutz gegen ein Aufbohren der Sperrorgane besitzen, indem diese das scheibenförmige Sicherheitselement mittig aufnehmen und welches mit einem Bohrwerkzeug mitdreht. Die mittige Aufnahme eines Sicherheitselementes im Sperrorgan kann zusätzlich zur Aufnahme eines Sicherheitselementes in einer Aufnahmetasche innerhalb des Schließzylinders vorgesehen sein.According to a further embodiment of the arrangement of the security element within the lock cylinder, this can even be formed as part of a locking member. In this case, the security element can be arranged as a disc-shaped central element in the blocking member, so that upon application of a certain torque on the security element, a rotational movement of the disc-shaped security element in the central region of the blocking member is generated. Thus, the locking members may be made in two parts and have a protection against drilling of the locking members by these centrally receive the disk-shaped security element and which rotates with a drilling tool. The central receiving a security element in the locking member may be provided in addition to receiving a security element in a receiving pocket within the lock cylinder.

Weitere, die Erfindung verbessernde Maßnahmen werden nachstehend gemeinsam mit der Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung anhand der Figuren näher dargestellt.Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS.

Figur 1 zeigt ein Ausführungsbeispiel eines Schließzylinders 1 mit einem Zylinderkern 2, der drehbar in einem Zylindergehäuse 3 aufgenommen ist. Der Zylinderkern 2 erstreckt sich entlang eines Schlüsselkanals 5, in dem ein Schlüssel 6 eingeführt ist. Der Schlüsselkanal 5 bildet zudem die Rotationsachse des Zylinderkerns 2 im Zylindergehäuse 3. FIG. 1 shows an embodiment of a lock cylinder 1 with a cylinder core 2, which is rotatably received in a cylinder housing 3. The cylinder core 2 extends along a keyway 5 in which a key 6 is inserted. The keyway 5 also forms the axis of rotation of the cylinder core 2 in the cylinder housing. 3

In der Schnittebene befindet sich ein Sperrorgan 4, das regelmäßig als Zuhaltung oder Plattenzuhaltung bezeichnet wird. Im Zylinderkern 2 sind mehrere Sperrorgane 4 in Richtung des Schlüsselkanals 5 hintereinander angeordnet, von denen eines geschnitten dargestellt ist. Die Sperrorgane 4 können durch Einführen des Schlüssels 6 in den Schlüsselkanal 5 orthogonal zur Drehachse des Zylinderkerns 2 in einer Seitenrichtung bewegt werden, die in der vorliegenden Darstellung der Vertikalen entspricht. Wird der passende Schlüssel 6 aus dem Schlüsselkanal 5 entnommen, bewirkt eine Druckfeder 17, dass sich das Sperrorgan 4 in die Nut 18 bewegt, die unterhalb des Sperrorgans 4 innerhalb des Zylindergehäuses 3 eingebracht ist. Gegenüberliegend ist auf der oberen Seite eine weitere Nut 18 gezeigt, in die sich der zungenartige Fortsatz am Sperrorgan 4 hinein bewegt, wenn der Schlüssel 6 in den Schlüsselkanal 5 eingeführt wird. Korrespondiert der Schlüsselbart mit der geometrischen Ausgestaltung der Öffnung innerhalb des Sperrorgans 4, so ragt der zungenartige Fortsatz oberhalb und unterhalb der Öffnung im Sperrorgan 4 weder in die obere Nut 18 noch in die untere Nut 18. In dieser - in der Figur gezeigten - Position lässt sich folglich der Zylinderkern 2 innerhalb des Zylindergehäuses 3 drehen, da der ursprüngliche Formschluss zwischen dem Zylinderkern 2 und den Nuten 18 aufgehoben ist.In the cutting plane is a locking member 4, which is regularly referred to as tumbler or Plattenzuhaltung. In the cylinder core 2 a plurality of locking members 4 are arranged in the direction of the keyway 5 one behind the other, one of which is shown in section. The locking members 4 can be moved by inserting the key 6 in the keyway 5 orthogonal to the axis of rotation of the cylinder core 2 in a lateral direction, which in the present representation corresponds to the vertical. If the matching key 6 is removed from the keyway 5, a compression spring 17 causes the blocking member 4 to move into the groove 18, which is introduced below the blocking member 4 within the cylinder housing 3. Opposite a further groove 18 is shown on the upper side, in which the tongue-like extension moves on the locking member 4 in when the key 6 is inserted into the keyway 5. Corresponds to the key bit with the geometric configuration of the opening within the locking member 4, so protrudes the tongue-like extension above and below the opening in the locking member 4 neither in the upper groove 18 still in the lower groove 18. In this - shown in the figure - position Consequently, the cylinder core 2 rotate within the cylinder housing 3, since the original positive connection between the cylinder core 2 and the grooves 18 is repealed.

Damit das Sperrorgan 4 in der Vertikalen bewegt werden kann, ist das Sperrorgan 4 in einer Sperrorganaufnahme 9 im Zylinderkern 2 aufgenommen. Die Sperraufnahme 9 geht rechtsseitig in ein Federloch 16 über, in dem die Druckfeder 17 zur Vorspannung des Sperrorgans 4 eingesetzt ist.Thus, the locking member 4 can be moved in the vertical, the locking member 4 is received in a locking member receptacle 9 in the cylinder core 2. The locking receptacle 9 is on the right side in a spring hole 16 in which the compression spring 17 is used for biasing the locking member 4.

Figur 2 zeigt einen Zylinderkern 2 gemäß einem erfindungsgemäßen Ausführungsbeispiel. Der Zylinderkern 2 besitzt mehrere Sperrorganaufnahmen 9, an die sich jeweilige Federlöcher 16 anschließen. Zwischen zwei Sperrorganaufnahmen 9 ist eine Aufnahmetasche 8 in den Zylinderkern 2 eingebracht, in die das erfindungsgemäße Sicherheitselement 7 in Gestalt einer kreisförmigen Scheibe 7 eingesetzt werden kann. Die Position des Sicherheitselementes 7 entlang des Schlüsselkanals 5, der gleichzeitig die Richtung der Längserstreckung des Zylinderkerns 2 darstellt, ist durch die Position der Aufnahmetasche 8 vorgegeben, die sich zwischen zwei Sperrorganaufnahmen 9 befindet. FIG. 2 shows a cylinder core 2 according to an embodiment of the invention. The cylinder core 2 has a plurality of blocking organ receivers 9, to which respective spring holes 16 adjoin. Between two locking organ holders 9 a receiving pocket 8 is introduced into the cylinder core 2, in which the security element 7 according to the invention in the form of a circular disc 7 can be used. The position of the security element 7 along the keyway 5, which simultaneously represents the direction of the longitudinal extension of the cylinder core 2, is determined by the position of the receiving pocket 8, which is located between two locking organ receivers 9.

Vorderseitig besitzt der Zylinderkern 2 einen Kopfbereich 10, in den das Sicherheitselement 7 ebenfalls eingesetzt werden kann. Rückseitig schließt sich bei diesem Ausführungsbeispiel an den Zylinderkern 2 ein Mitnehmer 19 an, der mit den weiteren Schließfunktionsteilen des Zylinderkerns zur Öffnung der Klappe eines Kraftfahrzeugs mechanisch zusammenwirkt. Diese Wirkverbindung wird durch eine Drehbewegung des Mitnehmers 19 erreicht, die durch einen Schlüssel eingeleitet werden kann, der in den Schlüsselkanal 5 eingeführt wird.The front side of the cylinder core 2 has a head portion 10, in which the security element 7 can also be used. On the back side, in the case of this exemplary embodiment, a driver 19 adjoins the cylinder core 2, which interacts mechanically with the other closing functional parts of the cylinder core for opening the flap of a motor vehicle. This operative connection is achieved by a rotational movement of the driver 19, which can be initiated by a key which is inserted into the keyway 5.

Die Figuren 3 und 4 zeigen weitere perspektivische Ansichten eines Zylinderkerns 2 gemäß der vorliegenden Erfindung. In Figur 3 ist das Sicherheitselement 7 in einer Explosionsdarstellung in Gestalt einer Scheibe schwebend vor dem Zylinderkern 2 gezeigt, wobei das Sicherheitselement 7 in Figur 4 im eingesetzten Zustand innerhalb des Zylinderkerns 2 gezeigt ist. Um das Sicherheitselement 7 in der Aufnahmetasche 8 im Zylinderkern 2 zu sichern, ist ein Verschlusselement 14 vorgesehen. Dieses ist sichelförmig oder halbmondförmig ausgeführt und verschließt die Öffnung der Aufnahmetasche 8, die in Richtung zur Mantelfläche des Zylinderkerns 2 weist. Gemäß dem vorliegenden Ausführungsbeispiel befindet sich die Aufnahmetasche 8 wiederum zwischen mehreren Sperrorganaufnahmen 9, die sich in Richtung zum Mitnehmer 19 hinter der Position der Aufnahmetasche 8 im Zylinderkern 2 befinden.The FIGS. 3 and 4 show further perspective views of a cylinder core 2 according to the present invention. In FIG. 3 the security element 7 is shown in an exploded view in the form of a disk floating in front of the cylinder core 2, wherein the security element 7 in FIG. 4 is shown in the inserted state within the cylinder core 2. In order to secure the security element 7 in the receiving pocket 8 in the cylinder core 2, a closure element 14 is provided. This is executed sickle-shaped or crescent-shaped and closes the opening of the receiving pocket 8, which has in the direction of the lateral surface of the cylinder core 2. According to the present embodiment, the receiving pocket 8 is again between a plurality Lock organ receivers 9, which are located in the direction of the driver 19 behind the position of the receiving pocket 8 in the cylinder core 2.

Im Sicherheitselement 7 ist eine Öffnung 13 eingebracht, die gerade so groß ist, um den Schlüsselkanal 5 nicht durch das Sicherheitselement 7 zu unterbrechen, so dass ein Schlüssel 6 in den Schlüsselkanal 5 ungehindert eingefügt werden kann. Die Öffnung 13 besitzt eine an den beispielhaften Schlüssel 6 angepasste rechteckförmige, längliche Erstreckung, deren Position vorgegeben sein muss, um das Einführen des Schlüssels 6 ungehindert sicher zu stellen. Zur Festlegung der Drehposition des Sicherheitselementes 7 ist sowohl innerhalb der Aufnahmetasche 8 eine Sperrnase 11 als auch im Verschlusselement 14 eine Sperrnase 15 vorgesehen. Die Sperrnasen 11 und 15 greifen in eine jeweilige Sperrnut 12 innerhalb des Sicherheitselementes 7 ein, so dass die Drehposition festgelegt ist. In der Schnittansicht gemäß Figur 4 ist die Position sowohl der Sperrnase 11 als auch der Sperrnase 15 dargestellt, durch die die Drehposition des scheibenförmigen Sicherheitselementes 7 festgelegt ist.In the security element 7, an opening 13 is introduced, which is just so large as not to interrupt the keyway 5 by the security element 7, so that a key 6 can be inserted into the keyway 5 unhindered. The opening 13 has an adapted to the exemplary key 6 rectangular, elongated extension whose position must be specified to ensure the insertion of the key 6 unhindered. In order to determine the rotational position of the security element 7, a blocking lug 11 as well as in the closure element 14 a locking lug 15 is provided both within the receiving pocket 8. The locking lugs 11 and 15 engage in a respective locking groove 12 within the security element 7, so that the rotational position is fixed. In the sectional view according to FIG. 4 the position of both the locking lug 11 and the locking lug 15 is shown, through which the rotational position of the disc-shaped security element 7 is fixed.

Wird auf das Sicherheitselement 7 beispielsweise durch ein Bohrwerkzeug ein Drehmoment aufgebracht, so dient die Verdrehsperrung zwischen der Sperrnut 12 und der Sperrnase 11 als Sollbruchstelle, und das Sicherheitselement 7 kann in der Aufnahmetasche mit einem Bohrer mitdrehen, wodurch eine Fortsetzung eines Bohrvorganges in den Schlüsselkanal 5 verhindert ist.If a torque is applied to the security element 7, for example by a drilling tool, then the rotation lock between the locking groove 12 and the locking lug 11 serves as a predetermined breaking point, and the security element 7 can rotate in the receiving pocket with a drill, thereby continuing a drilling operation in the keyway 5 is prevented.

In den Figuren 5a und 5b sind weitere perspektivische Ansichten des erfindungsgemäßen Zylinderkerns 2 gezeigt. Figur 5a zeigt den Zylinderkern 2 mit dem Mitnehmer 19 sowie dem Kopfbereich 10, wobei Figur 5b einen geschnittenen Zylinderkern 2 darstellt, wobei die Schnittebene im Bereich der Aufnahmetasche 8 liegt. Gemäß der Darstellung ist erkennbar, dass die Sperrorganaufnahmen 9 jeweils 180° zueinander versetzte Richtungen aufweisen, die jeweils abwechselnd zueinander im Zylinderkern 2 eingebracht sind. Die Aufnahmetasche 8 zur Aufnahme des Sicherheitselementes 7 befindet sich in einer Position nach zwei Sperrorganaufnahmen 9, die sich an den Kopfbereich 10 des Zylinderkerns 2 anschließen. Hinter der Aufnahmetasche 8 zur Aufnahme des Sicherheitselementes 7 schließen sich vier Sperrorganaufnahmen 9 in einer ersten Richtung und drei Sperrorganaufnahmen 9 in einer zweiten Richtung an, die jeweils 90° zueinander versetzt quer durch den Zylinderkern 2 hindurch laufen.In the FIGS. 5a and 5b Further perspective views of the cylinder core 2 according to the invention are shown. FIG. 5a shows the cylinder core 2 with the driver 19 and the head portion 10, wherein FIG. 5b represents a cut cylinder core 2, wherein the cutting plane is in the region of the receiving pocket 8. According to the illustration, it can be seen that the blocking organ receivers 9 each have directions offset from one another by 180 °, which are each introduced alternately to one another in the cylinder core 2. The receiving pocket 8 for receiving the security element 7 is located in a position after two locking organ receivers 9, which adjoin the head portion 10 of the cylinder core 2. Behind the receiving pocket 8 for receiving the security element 7 close four lock organ receptacles 9 in a first direction and three Lock organ receptacles 9 in a second direction, each offset by 90 ° to each other transversely through the cylinder core 2 through.
