A blocking member (5), which follows the housing pin (9) on an attempt to release the lock, has a component (11) guided to move in the housing pin (9) and magnetically connected to the rotor pin (12).

Description

Federbelastete Zuhaltung in einem Drehschliesszylinder für ein SicherheitsschlossSpring-loaded tumbler in a rotary lock cylinder for a security lock
Die Erfindung betrifft eine federbelastete Zuhaltung in ei¬ nem Drehschliesszylinder für ein Sicherheitsschloss, mit einem Rotorstift und einem Gehäusestift, die mit einem in einen Schlüsselkanal des Drehschliesszylinders eingeführten Steckschlüssel zur Drehfreigabe des Rotors eingeordnet wer¬ den und mit einem Sperrorgan, das bei einem Aufsperrversuch dem Gehäusestift folgt.The invention relates to a spring-loaded tumbler in a rotary lock cylinder for a security lock, with a rotor pin and a housing pin, which are arranged with a socket wrench inserted into a key channel of the rotary lock cylinder to enable the rotor to rotate, and with a locking element which, when attempting to unlock the lock Housing pin follows.
Eine Zuhaltung dieser Art ist aus der CH-A-669 633 des An¬ melders bekannt geworden. Diese besitzt in einer Bohrung des Kernstifts einen Sperrstift und eine Druckfeder. Die Druckfeder drückt mit Vorspannung auf den Sperrstift, der seinerseits auf den am Kernstift anliegenden Gehäusestift drückt. Wird bei einem Aufsperrversuch der Gehäusestift vom Kernstift abgehoben, so folgt der Sperrstift im wesentli¬ chen verzögerungsfrei dem Gehäusestift und verriegelt den Rotor.A guard lock of this type has become known from the applicant's CH-A-669 633. This has a locking pin and a compression spring in a hole in the core pin. The compression spring presses with pretension on the locking pin, which in turn presses on the housing pin resting on the core pin. If the housing pin is lifted from the core pin during an unlocking attempt, the locking pin follows the housing pin essentially without delay and locks the rotor.
Für unbefugte Aufsperrmethoden, die vor allem nach dem Hub- b1sehen Verfahren arbeiten, werden zunehmend leistungsfähi¬ gere Instrumente angeboten. Es besteht deshalb ein dringen¬ der Bedarf nach weiteren Zuhaltungen, die der Weiterent¬ wicklung solcher Einbruchwerkzeuge Rechnung tragen. Der Erfindung liegt die Aufgabe zugrunde, eine Zuhaltung der genannten Art zu schaffen, deren AufSperrsicherheit den höheren Sicherheitsanforderungen Rechnung trägt. Unter Auf¬ sperrsicherheit wird der Grad der Erschwerung verstanden, die Zuhaltungen eines Schliesszylinders mit Hilfsmitteln ohne Kenntnis des Schliesscodes zerstörungsfrei einzuord¬ nen.More powerful instruments are increasingly being offered for unauthorized unlocking methods, which operate primarily according to the Hub 1 method. There is therefore an urgent need for further tumblers which take into account the further development of such burglary tools. The invention has for its object to provide a guard locking of the type mentioned, the unlocked security takes into account the higher security requirements. Unlocking security is understood to mean the degree of difficulty in classifying the tumblers of a locking cylinder with non-destructive means without knowledge of the locking code.
Die Aufgabe ist bei einer gattungsgemässen Zuhaltung da¬ durch gelöst, dass das Sperrorgan einen vorzugsweise im Ge¬ häusestift verschieblich geführten Teil aufweist, der ma¬ gnetisch mit dem Rotorstift verbunden ist. Beim befugten Einordnen der Zuhaltung mit einem zugehörigen Steckschlüs¬ sel kann die magnetische Verbindung des verschieblich ge¬ führten Teils mit dem Rotorstift beim Drehen des Rotors im wesentlichen ohne zusätzlichen Kraftaufwand getrennt wer¬ den. Bei einem unbefugten Aufsperrversuch bleibt hingegen der verschieblich geführte Teil immer mit dem Kernstift verbunden. Der verschieblich geführte Teil folgt damit im¬ mer verzögerungsfrei dem Kernstift.The object is achieved in the case of a generic guard locking device in that the locking member has a part which is preferably displaceably guided in the housing pin and which is magnetically connected to the rotor pin. When the guard locking is authorized with an associated socket wrench, the magnetic connection of the displaceably guided part to the rotor pin can be separated substantially without additional force when the rotor is rotated. In the event of an unauthorized unlocking attempt, however, the part that can be moved remains connected to the core pin. The displaceably guided part therefore always follows the core pin without delay.
Der verschieblich geführte Teil ist gemäss einer Weiterbil¬ dung der Erfindung ein Stift, der in einer Längsbohrung des Gehäusestiftes gelagert ist. Der Stift ist vorzugsweise ein Stahlbolzen, der im Gehäusestift frei verschiebbar gelagert ist und der im Fall eines Aufsperrversuches sperrt und ab¬ geschert werden müsste. Nach einer Weiterbildung der Erfin¬ dung weist der Rotorstift ein Federelement auf, das mittel¬ bar oder unmittelbar am Gehäusestift abgestützt ist und das den Rotorstift radial nach innen belastet. Dieses Federele¬ ment drückt den Rotorstift dauernd radial nach innen. Bei einem Aufsperrversuch, bei dem der Gehäusestift radial nach aussen bewegt wird, wird der radial geführte Teil des Sperrorgans durch die magnetische Fixierung immer in einer Position gehalten, in der dieser verschieblich geführte Teil die Scherlinie des Rotors überschreitet und damit sperrt. Eine Freigabe des Rotors wäre somit nur dann mög¬ lich, wenn der Gehäusestift und gleichzeitig der Rotorstift eingeordnet werden.According to a further development of the invention, the displaceably guided part is a pin which is mounted in a longitudinal bore of the housing pin. The pin is preferably a steel bolt which is freely displaceably mounted in the housing pin and which would have to be locked and sheared off in the event of an attempt to unlock it. According to a further development of the invention, the rotor pin has a spring element which is supported directly or indirectly on the housing pin and which loads the rotor pin radially inwards. This spring element continuously presses the rotor pin radially inwards. During an unlocking attempt in which the housing pin is moved radially outward, the radially guided part of the blocking member is always held in a position by the magnetic fixation in which this displaceably guided part exceeds the shear line of the rotor and thus locks. A release of the rotor would therefore only be possible if the housing pin and the rotor pin were arranged at the same time.
Eine besonders starke magnetische Verbindung ist dann rea¬ lisierbar, wenn das Sperrorgan einen Dauermagneten aus ei¬ ner Legierung aufweist, welche Metalle aus der Gruppe der Lanthaniden enthält. Damit ist es möglich, auch mit einem sehr kleinen magnetischen Teil eine hohe Haftkraft auszu¬ üben. Der dauermagnetische Teil kann damit als Stift mit einem Durchmesser von beispielsweise 0,5 mm realisiert wer¬ den.A particularly strong magnetic connection can be achieved if the blocking member has a permanent magnet made of an alloy which contains metals from the group of the lanthanides. This makes it possible to exert a high adhesive force even with a very small magnetic part. The permanent magnetic part can thus be realized as a pin with a diameter of, for example, 0.5 mm.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an¬ hand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to the drawing. Show it:

Figur 2 ein Schnitt gemäss Figur 1 jedoch mit einem in den Schlüsselkanal eingeführten Steckschlüssel, und2 shows a section according to FIG. 1, however, with a socket wrench inserted into the key channel, and
Figur 3 eine Darstellung gemäss Figur 1 , wobei die Zu¬ haltung hier in einem Zustand während eines AufSperrversuches gezeigt ist.FIG. 3 shows an illustration according to FIG. 1, the locking being shown here in a state during an unlocking attempt.
Ein hier nur abschnittsweise gezeigter, an sich üblicher Drehschliesszylinder 1 weist ein Gehäuse 2 mit einer Längs¬ bohrung 27 auf, in der ein Rotor 3 gelagert ist. In den Ro¬ tor 3 ist ein Schlüsselkanal 22 eingearbeitet, in den zum Einordnen einer Zuhaltung 4 ein Schlüssel 23 einzuführen ist. Hierbei wird die Zuhaltung 4 mittels einer Bohrung 29 im Schlüssel 23 in einer radialen Bohrung 24 gegen die rückwirkende Kraft einer Gehäusefeder 8 radial nach aussen bewegt und eingeordnet. Die Figur 2 zeigt die eingeordnete Zuhaltung 4. Der Rotor 3 ist hier durch die Zuhaltung 4 nicht gesperrt und kann mit dem Schlüssel 23 gedreht und ein hier nicht gezeigter Riegel eines Schlosses betätigt werden. Der Schliesszylinder 1 weist in der Regel mehrere solche Zuhaltungen 4 auf.A rotary lock cylinder 1, which is shown here only in sections and is conventional, has a housing 2 with a longitudinal bore 27 in which a rotor 3 is mounted. A key channel 22 is incorporated into the rotor 3, into which a key 23 is inserted in order to arrange a tumbler 4 is. Here, the tumbler 4 is moved and arranged radially outwards by means of a bore 29 in the key 23 in a radial bore 24 against the retroactive force of a housing spring 8. FIG. 2 shows the arranged tumbler 4. The rotor 3 is not locked here by the tumbler 4 and can be turned with the key 23 and a bolt of a lock, not shown here, can be actuated. The locking cylinder 1 generally has several such tumblers 4.
Bei der gezeigten Ausführung ist der Gehäusestift 9 in ei¬ ner Bohrung 7 eines an sich bekannten Schiebers 6 gelagert. In einer durchgehenden Längsbohrung 10 des Gehäusestiftes 9 ist ein Stahlstift 11 verschieblich geführt. Dieser Stift 11 haftet magnetisch an einem Stift 16, der in eine Sack¬ bohrung 14 eines Rotorstiftes 12 eingesetzt ist und der in eine Bohrung 20 eingepresst ist. Der Stift 16 ist somit fest im Rotorstift 12 verankert. Der Stift 16 ist ein Dau¬ ermagnet und vorzugsweise aus einer Legierung aus seltenen Erdmetallen (Lanthaniden) hergestellt. Der Dauermagnet be¬ sitzt an seinem freien Ende eine ebene Stirnfläche 30, an der eine ebenfalls ebene Fläche 31 des Stiftes 11 anliegt. Bei der eingeordneten Zuhaltung 4 liegen die Flächen 30 und 31 in der Scherfläche 27 des Schliesszylinders 1. Beim Dre¬ hen des Rotors 3 ist somit bei eingeordneter Zuhaltung 4 ein seitliches Verschieben der Stifte 11 und 16 gegeneinan¬ der ohne weiteres möglich.In the embodiment shown, the housing pin 9 is mounted in a bore 7 of a slide 6 known per se. A steel pin 11 is slidably guided in a continuous longitudinal bore 10 of the housing pin 9. This pin 11 adheres magnetically to a pin 16 which is inserted into a blind bore 14 of a rotor pin 12 and which is pressed into a bore 20. The pin 16 is thus firmly anchored in the rotor pin 12. The pin 16 is a permanent magnet and is preferably made from an alloy of rare earth metals (lanthanides). The permanent magnet has a flat end face 30 at its free end, on which a likewise flat surface 31 of the pin 11 bears. In the case of the arranged tumbler 4, the surfaces 30 and 31 lie in the shear surface 27 of the locking cylinder 1. When the rotor 3 is rotated, the pins 11 and 16 can be easily moved laterally with respect to the arranged tumbler 4.
Der Gehäusestift 9 liegt mit einer vorderen Fläche 32 an einer Fläche 13 des Stiftes 12 an und hält diesen in der in Figur 1 gezeigten Stellung, in welcher der Stift 12 mit ei¬ ner Schulter 26 an einer Schulter 25 der Bohrung 24 an¬ liegt. In der Sackbohrung 14 ist eine Hülse 15 gelagert, die mit einer durchgehenden Stufenbohrung 17 den Stift 16 aufnimmt. Die Bohrung 14 nimmt eine Druckfeder 19 auf, wel¬ che die Hülse 15 gegen den Gehäusestift 9 spannt. Die Feder 19 besitzt eine Federkraft, die wesentlich kleiner ist als diejenige der Feder 8. Die Bedeutung der Feder 19 ist wei¬ ter unten erläutert.The housing pin 9 bears with a front surface 32 against a surface 13 of the pin 12 and holds it in the position shown in FIG. 1, in which the pin 12 lies with a shoulder 26 against a shoulder 25 of the bore 24. In the blind bore 14, a sleeve 15 is mounted, which receives the pin 16 with a continuous stepped bore 17. The bore 14 receives a compression spring 19 which stretches the sleeve 15 against the housing pin 9. The spring 19 has a spring force that is significantly less than that of the spring 8. The meaning of the spring 19 is explained further below.
Die Wirkungsweise der Zuhaltung 4 wird nachfolgend anhand der Zeichnung näher erläutert.The mode of operation of the tumbler 4 is explained in more detail below with reference to the drawing.
Bei der befugten Einordnung der Zuhaltung 4 mit einem Schlüssel 23 sind die Stifte 11 und 16 gemäss Figur 2 so angeordnet, dass diese beim Drehen des Rotors 3 seitlich gegeneinander verschoben werden können. Die Zuhaltung 4 ar¬ beitet hier somit wie eine übliche Zuhaltung ohne Sperror¬ gan.In the authorized arrangement of the tumbler 4 with a key 23, the pins 11 and 16 according to FIG. 2 are arranged in such a way that they can be moved laterally against each other when the rotor 3 is rotated. The tumbler 4 thus works like a normal tumbler without a locking device.
Wird nun gemäss Figur 3 bei einem Aufsperrversuch der Ge¬ häusestift 9 nach aussen in das Gehäuse 2 bewegt, so bleibt der Stift 11 am dauermagnetischen Stift 16 haften und ver¬ bleibt in der in Figur 3 gezeigten Sperrstellung. Der Stift 11 überschreitet wie ersichtlich die Scherfläche 27 und müsste zur Drehfreigabe des Rotors 3 durchgeschert werden. Da der Stift 11 in der Bohrung 10 frei verschiebbar ist, kann dieser auch durch ein Verkanten des Rotors im Gehäuse¬ stift 9 nicht fixiert werden. Zur Drehfreigabe des Schliesszylinders müsste somit auch der Rotorstift 12 in die in Figur 2 gezeigte Stellung angehoben werden, was kaum möglich ist und hierbei zudem die rückwirkende Kraft der Feder 19 überwunden werden müsste.If, in accordance with FIG. 3, the housing pin 9 is moved outwards into the housing 2 during an unlocking attempt, the pin 11 remains attached to the permanent magnetic pin 16 and remains in the blocking position shown in FIG. 3. As can be seen, the pin 11 exceeds the shear surface 27 and would have to be sheared through to enable the rotor 3 to rotate. Since the pin 11 is freely displaceable in the bore 10, it cannot be fixed in the housing pin 9 even by tilting the rotor. To enable the lock cylinder to rotate, the rotor pin 12 would therefore also have to be raised to the position shown in FIG. 2, which is hardly possible and, in addition, the retroactive force of the spring 19 would have to be overcome.
Denkbar ist auch eine Ausführung, bei welcher der Stift 11 als Dauermagnet ausgebildet ist. Der Gehäusestift 9 wäre dann aus einem antimagnetischen Werkstoff herzustellen. Schliesslich ist auch eine Ausführung denkbar, bei welcher der Stift 11 fest mit dem Gehäusestift 9 verbunden ist und der Stift 16 im Rotorstift 12 frei verschiebbar gelagert ist. Eine wesentliche Verbesserung der Schliesssicherheit ist bereits dann gegeben, wenn der Schliesszylinder 1 we¬ nigstens eine Zuhaltung 4 gemäss der Erfindung aufweist. Einige Zuhaltungen des Schliesszylinders 1 können somit wie üblich ausgebildet sein. An embodiment is also conceivable in which the pin 11 is designed as a permanent magnet. The housing pin 9 would then be made of an anti-magnetic material. Finally, an embodiment is also conceivable in which the pin 11 is fixedly connected to the housing pin 9 and the pin 16 is freely displaceably mounted in the rotor pin 12. A substantial improvement in the security of the lock is given when the lock cylinder 1 has at least one tumbler 4 according to the invention. Some tumblers of the lock cylinder 1 can thus be designed as usual.
