Abstract

The rotatable lock cylinder has blocking element (14) which is composed of two parts (15, 16) between which a spring element (18) is arranged. The two parts are separated from each other in case of an unplaced core pin such that the two parts cannot be reunited. The blocking element rests in a spring-loaded manner against an outer surface of the rotor and blocks the rotor.

Description

Die Erfindung betrifft einen Drehschliesszylinder für ein Sicherheitsschloss, mit einem Stator und einem einen Schlüsselkanal aufweisenden Rotor, mit Zuhaltungen, die zur Drehfreigabe des Rotors mit einem zugehörigen Schlüssel einzuordnen sind und die jeweils einen Kernstift und einen federbelasteten Gehäusestift aufweisen, wobei in Drehrichtung des Rotors gesehen nach der Grundstellung im Stator wenigstens ein Sperrorgan angeordnet ist, das federbelastet an der Mantelfläche des Rotors anliegt und das den Rotor sperrt, wenn ein nicht eingeordneter Kernstift seine Position erreicht.The invention relates to a rotary lock cylinder for a safety lock, with a stator and a keyway having a rotor, with tumblers, which are classified for the rotational release of the rotor with an associated key and each having a core pin and a spring-loaded housing pin, being seen in the direction of rotation of the rotor after the basic position in the stator at least one locking member is arranged, the spring-loaded abuts against the lateral surface of the rotor and which locks the rotor when an unadjusted core pin reaches its position.

Drehschliesszylinder dieser Art sind seit langem bekannt, sie gewährleisten eine hohe Sicherheit. Wie andere Sicherheitseinrichtungen sind sie Manipulationen zum unberechtigten Öffnen ausgesetzt. Eine bekannte Öffnungsmethode wird als "Schlagtechnik" bezeichnet. Die Öffnungsmethode ist spurenarm und beschädigt den Schliesszylinder nicht grundsätzlich. Ein Einbruchversuch ist nachträglich in der Regel nicht am Drehschliesszylinder feststellbar. Ein Problem sind zudem Einschleichdiebstähle mit entwendeten Schlüsseln.Rotary lock cylinder of this type have long been known, they ensure a high level of security. Like other security devices, they are subject to manipulation for unauthorized opening. One known opening method is referred to as a "beating technique". The opening method is low-profile and does not fundamentally damage the lock cylinder. A burglary attempt is subsequently not usually detected on the rotary lock cylinder. A problem is also creep theft with stolen keys.

Durch die DE-A-199 34 883 ist ein Drehschliesszylinder der genannten Art bekannt geworden. Bei diesem ist im Stator ein Sperrorgan vorgesehen, das einen Draht mit einem vorne an diesem angebrachten tellerförmigen Teil aufweist. Wird beim Drehen des Rotors ein Kernstift nicht korrekt eingeordnet und erreicht dieser das genannte Sperrorgan, so verklemmt der Draht zwischen dem Rotor und dem Stator und führt zur Blockierung des Rotors, so dass das Schloss nicht geöffnet werden kann. Mit einigem Geschick ist es hier jedoch möglich, das tellerförmige Teil wieder zurück in die ursprüngliche Lage, d.h. in die Bohrung des Gehäuses zurückzubringen. Dadurch ist es möglich, einen weiteren Manipulationsversuch zu unternehmen, der dann möglicherweise erfolgreich ist.By the DE-A-199 34 883 is a rotary lock cylinder of the type mentioned become known. In this, a blocking member is provided in the stator, which has a wire with a front attached to this dish-shaped part. If, when turning the rotor, a core pin is not correctly positioned and reaches the said locking element, the wire jams between the rotor and the stator and blocks the rotor so that the lock can not be opened. With some skill it is here However, possible, the plate-shaped part back to the original position, ie bring back into the bore of the housing. This makes it possible to make another manipulation attempt, which may then be successful.

Ein ähnlicher Drehschliesszylinder ist aus der FR-A-23 12 630 bekannt geworden. Das Sperrorgan besteht hier aus einem pilzförmigen Bolzen und einer Feder.A similar rotary lock cylinder is from the FR-A-23 12 630 known. The locking member here consists of a mushroom-shaped bolt and a spring.

Durch die US-A-3,802,234 ist ein Drehschliesszylinder mit einem Sperrorgan offenbart, das aus einem Federelement und drei weiteren Teilen besteht. Die zwei Teile bilden einen Spreizstift. Bei einem nicht eingeordneten Kernstift fährt ein hinteres Teil in den Spreizstift und dessen Teile verkeilen sich schliesslich in einer Stufenbohrung des Gehäuses, so dass dieser nicht wieder zurück in die Gehäusebohrung gebracht werden kann. Die Herstellung eines solchen Sperrorgans und insbesondere seine Montage wäre jedoch sehr aufwändig.By the US-A-3,802,234 discloses a rotary lock cylinder with a locking member, which consists of a spring element and three other parts. The two parts form a spreader pin. In a non-classified core pin drives a rear part in the expander pin and its parts finally wedge in a stepped bore of the housing so that it can not be brought back into the housing bore. The preparation of such a locking member and in particular its installation would be very complicated.

Der Erfindung liegt die Aufgabe zugrunde, ein Drehschliesszylinder der genannten Art zu schaffen, der noch sicherer Manipulationen verhindert und der dennoch kostengünstig hergestellt und montiert werden kann.The invention has for its object to provide a rotary lock cylinder of the type mentioned, which prevents even safer manipulation and yet can be inexpensively manufactured and assembled.

Die Aufgabe ist bei einem gattungsgemässen Drehschliesszylinder dadurch gelöst, dass das Sperrorgan aus zwei Teilen besteht, zwischen denen ein Federelement angeordnet ist und die im Fall eines nicht eingeordneten Kernstifts so voneinander getrennt werden, dass sie nicht mehr zusammengefügt werden können.The object is achieved in a generic rotary lock cylinder characterized in that the locking member consists of two parts, between which a spring element is arranged and which are separated in the case of an unordered core pin so that they can not be joined together.

Das erfindungsgemässe Sperrorgan kann aus lediglich drei Teilen hergestellt werden. Das innere Teil verbleibt auch im Fall einer Manipulation grundsätzlich in der Gehäusebohrung, kann aber nicht mehr zurück in die ursprüngliche Position gebracht werden. Der Rotor kann somit weder im Uhrzeigersinn noch im Gegenuhrzeigersinn gedreht werden. Der erfindungsgemässe Drehschliesszylinder eignet sich insbesondere für eine Fangschliessung, mit der es möglich ist, einen ersetzten früheren Schlüssel so im Drehschliesszylinder zu fixieren, dass dieser nicht abgezogen werden kann.The blocking member according to the invention can be produced from only three parts. The inner part remains in the case of a manipulation basically in the housing bore, but can not be brought back to the original position. The rotor can thus be rotated neither clockwise nor counterclockwise. The inventive rotary lock cylinder is particularly suitable for a catch closure, with which it is possible to fix a replaced earlier key in the rotary lock cylinder, that this can not be deducted.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass ein äusseres Teil des Sperrorgans ein Führungsteil und ein zweites inneres Teil ein Sperrelement ist. Das Sperrorgan sperrt dann besonders zuverlässig, wenn gemäss einer Weiterbildung der Erfindung das Sperrelement teleskopisch und radial im Führungselement geführt ist. Die teleskopische Führung ist so ausgebildet, dass diese aufgehoben wird, sobald ein nicht eingeordneter Kernstift auf das Sperrelement trifft. Diese Führung kann vergleichsweise präzise ausgebildet sein, so dass ein Wiedereinführen des Sperrelements in das Führungsteil praktisch ausgeschlossen ist.According to a development of the invention it is provided that an outer part of the blocking member is a guide member and a second inner part is a blocking element. The blocking member then locks particularly reliably if, according to a development of the invention, the blocking element is guided telescopically and radially in the guide element. The telescopic guide is designed so that it is canceled as soon as an unordered core pin strikes the blocking element. This guide can be designed comparatively precise, so that a reintroduction of the locking element in the guide member is practically impossible.

Die Erfindung betrifft zudem einen Drehschliesszylinder mit einer Fangschliessung. Bei diesem ist das genannte Sperrorgan in Drehrichtung des Rotors gesehen nach einem Gehäusestift angeordnet, der wenigstens zwei Stufensprünge überbrücken kann. Dieser Gehäusestift besitzt insbesondere eine konische oder kugelförmige Stirnfläche. Bei einem solchen Drehschliesszylinder kann eine Fangschliessung lediglich durch Austauschen eines Kernstifts eingerichtet werden. Der bisherige Schlüssel wird dann durch einen Schlüssel ersetzt, welcher dem neuen Kernstift entspricht. Mit dem bisherigen Schlüssel kann der Rotor bis zum Sperrorgan gedreht werden. Sobald dieses erreicht ist, werden durch die genannte Feder die beiden Teile getrennt und das innere Teil sperrt den Rotor. Da das innere Teil radial nicht mehr nach aussen bewegt werden kann, bleibt der entsprechende Kernstift in Eingriff mit dem Schlüssel, der damit nicht mehr abgezogen werden kann und damit gefangen ist. Da der Rotor nicht mehr gedreht werden kann, kann der Schlüssel nicht abgezogen werden und das Schloss kann auch nicht geöffnet werden. Damit ist auch ersichtlich, dass unberechtigt versucht wurde, das Schloss zu öffnen.The invention also relates to a rotary lock cylinder with a catch closure. In this, said locking member is arranged in the direction of rotation of the rotor arranged according to a housing pin, which can bridge at least two increments. This housing pin in particular has a conical or spherical end face. In such a rotary lock cylinder, a catch closure can be set up only by exchanging a core pin. The previous key is then replaced by a key corresponding to the new core pin. With the previous key, the rotor can be turned to the locking device. Once this is achieved, the two parts are separated by the said spring and the inner part locks the rotor. Since the inner part can not be radially moved outward, the corresponding core pin remains in engagement with the key, which can thus no longer be removed and thus caught. Since the rotor can no longer be rotated, the key can not be removed and the lock can not be opened. This also shows that an unauthorized attempt was made to open the lock.

Die Figuren 3 und 4 zeigen einen an sich bekannten Drehschliesszylinder 1' für ein Sicherheitsschloss, der einen Stator 3 aufweist, in dem ein Rotor 2 angeordnet ist. Der Stator 3 bildet das Gehäuse und weist einen hier nur teilweise gezeigten Zylindersack 8 auf. Der Drehschliesszylinder 1' weist eine Mehrzahl von Zuhaltungen auf, von denen hier die Zuhaltungen Z1, Z2 und Z3 gezeigt sind. Diese Zuhaltungen Z1 bis Z3 besitzen jeweils einen Gehäusestift 25, der in einem Schieber 7 gelagert ist, und gegen die rückwirkende Kraft einer Druckfeder 26 radial nach aussen verschiebbar ist. Die Schieber 7 sind jeweils achsial in eine Nut 27 (Fig. 2) des Stators 3 eingesetzt und besitzen mehrere Bohrungen 12 zur Aufnahme jeweils eines Gehäusestifts 25.The FIGS. 3 and 4 show a known rotary lock cylinder 1 'for a security lock, which has a stator 3, in which a rotor 2 is arranged. The stator 3 forms the housing and has a cylinder bag 8, which is only partially shown here. The rotary lock cylinder 1 'has a plurality of tumblers, of which the tumblers Z1, Z2 and Z3 are shown here. These tumblers Z1 to Z3 each have a housing pin 25 which is mounted in a slide 7, and against the retroactive force of a compression spring 26 is displaced radially outward. The slides 7 are each axially into a groove 27 (FIG. Fig. 2 ) of the stator 3 and have a plurality of bores 12 for receiving a respective housing pin 25th

In der Figur 3 sperren sämtliche Gehäusestifte 25 den Rotor 2 negativ, d.h. sie übergreifen die Trennlinie T bzw. Scherlinie zwischen dem Rotor 2 und dem Stator 3. Die Gehäusestifte 25 liegen an einem Bolzen 10, 10a bzw. 10b an. Wird in einem Schlüsselkanal 5 des Rotors 2 ein in Figur 4 gezeigter Schlüssel 4 eingesetzt, so werden die Zuhaltungen Z1 bis Z3 gemäss Figur 4 eingeordnet. Der Rotor 2 ist damit frei und kann gedreht werden. Zum Einordnen der Zuhalten Z1 bis Z3 besitzt der Schlüssel 4 Bohrungen 9, die je nach Länge der Kernstifte 10, 10a und 10b unterschiedlich tief sind. Diese Bohrungen 9 bilden Steuerflächen für die entsprechenden Zuhaltungen. In der Figur 4 arbeitet der Kernstift 10 mit der Bohrung 9 zusammen. Wird der Schlüssel 4 abgezogen, so fällt der Kernstift 10 in die in Figur 3 gezeigte Stellung. Der Gehäusestift 25 der Zuhaltung Z3 folgt dem Kernstift 10 aufgrund der Spannung der Feder 26 sperrt nun gemäss Figur 3 den Rotor 2.In the FIG. 3 Lock all housing pins 25 the rotor 2 negative, ie they overlap the dividing line T or shear line between the rotor 2 and the stator 3. The housing pins 25 are applied to a bolt 10, 10a and 10b. Is in a keyway 5 of the rotor 2 in FIG. 4 used key 4, the tumblers Z1 to Z3 according to FIG. 4 classified. The rotor 2 is thus free and can be rotated. To classify the pawls Z1 to Z3, the key has 4 holes 9, which are different depths depending on the length of the core pins 10, 10a and 10b. These holes 9 form control surfaces for the corresponding tumblers. In the FIG. 4 the core pin 10 cooperates with the bore 9. If the key 4 is removed, the core pin 10 falls into the in FIG. 3 shown position. The housing pin 25 of the tumbler Z3 follows the core pin 10 due to the tension of the spring 26 now locks according to FIG. 3 the rotor 2.

Der in Figur 5 gezeigte erfindungsgemässe Schliesszylinder 1 weist zusätzlich zu dem in den Figuren 3 und 4 gezeigten Drehschliesszylinder 1' einen weiteren Schieber 7' mit wenigstens einem Sperrorgan 14 auf. Der beim Drehschliesszylinder 1' vorgesehene Kernstift 10 ist durch einen kürzeren Kernstift 10' ersetzt. Zudem besitzt die Zuhaltung Z3' einen Gehäusestift 29 mit einer Stirnfläche 30, die wie ersichtlich konisch ausgebildet ist. Diese Stirnfläche 30 kann alternativ auch kugelförmig oder dergleichen ausgebildet sein.The in FIG. 5 shown locking cylinder 1 has in addition to the in the FIGS. 3 and 4 shown rotary lock cylinder 1 'a further slide 7' with at least one locking member 14. The case of the rotary lock cylinder 1 'provided core pin 10 is replaced by a shorter core pin 10'. In addition, the tumbler Z3 'has a housing pin 29 with an end face 30, which is conical as shown. This end face 30 may alternatively also be spherical or the like.

Das Sperrorgan 14 ist in der Figur 1 stark vergrössert dargestellt. Es besteht aus drei Teilen, und zwar einem Führungsteil 16, einem Sperrelement 1 S und einer zwischen diesen angeordneten vergleichsweise starken Druckfeder 18. Beide Teile 15 und 16 sind wie ersichtlich becherförmig ausgebildet. Das Sperrelement 15 besitzt eine ebene Frontfläche 19, die gemäss Figur 5 unter Spannung an einer Mantelfläche 6 des Rotors 2 anliegt. Das Sperrelement 15 besitzt zudem eine Fläche 21, die parallel zur Fläche 19 verläuft und die sich in einer Ausnehmung 17 des Führungsteils 16 befindet. Die Fläche 21 befindet sich wie ersichtlich im Abstand D zu einer Fläche 22, die eine Frontseite des Führungsteils 16 bildet. Das Sperrelement 15 ist im Führungsteil 16 verschiebbar geführt. Ein Zwischenraum 31 zwischen dem Führungsteil 16 und einer Fläche 24 des Sperrelements 15 ist vergleichsweise klein, das Sperrelement 15 ist somit mit geringer Toleranz im Führungsteil 16 geführt. Das Sperrelement 15 besitzt innenseitig eine Ausnehmung 20, in welche die Feder 18 eingreift und eine Fläche 28, an welcher die Feder 18 anliegt. Die Feder 18 liegt zudem an einer inneren Fläche 23 des Führungsteils 16 an.The locking member 14 is in the FIG. 1 shown greatly enlarged. It consists of three parts, namely a guide member 16, a blocking element 1 S and a comparatively strong compression spring 18 arranged between them. Both parts 15 and 16 are cup-shaped, as can be seen. The blocking element 15 has a flat front surface 19, according to FIG. 5 under tension against a lateral surface 6 of the rotor 2. The blocking element 15 also has a surface 21 which extends parallel to the surface 19 and which is located in a recess 17 of the guide member 16. The surface 21 is located as shown at a distance D to a surface 22 which forms a front side of the guide member 16. The blocking element 15 is guided displaceably in the guide part 16. An intermediate space 31 between the guide part 16 and a surface 24 of the blocking element 15 is comparatively small, the blocking element 15 is thus guided with a small tolerance in the guide part 16. The blocking element 15 has an inside Recess 20, in which engages the spring 18 and a surface 28 against which the spring 18 abuts. The spring 18 also bears against an inner surface 23 of the guide member 16.

In der Figur 4 befindet sich der Rotor 2 in der Grundstellung. In den Schlüsselkanal 5 ist ein Schlüssel 4' eingesetzt, der sich vom bisherigen Schlüssel 4 durch eine entsprechend weniger tiefe Bohrung 9' auszeichnet. Der Gehäusestift 29 ist hier korrekt eingeordnet, so dass der Rotor 2 in die in Figur 7 gezeigte Stellung drehbar ist. Der Kernstift 10 befindet sich nun gemäss Figur 7 auf der Höhe des Sperrorgans 14. Er ordnet das Sperrorgan 14 wie ein üblicher Gehäusestift ein. Das Sperrorgan 14 sperrt somit nicht und der Rotor 2 kann zum Öffnen des hier nicht gezeigten Schlosses weiter im Uhrzeigersinn gedreht werden. Die Figur 8 zeigt den Drehschliesszylinder 1 in der gleichen Position wie in Figur 6, wobei hier jedoch in den Schlüsselkanal 5 der Schlüssel 4, d.h. somit der alte Schlüssel eingesetzt ist. Wie ersichtlich, überschreitet der Gehäusestift 29 mit seiner Stirnfläche 30 die Trennlinie T, da die Bohrung 9 des Schlüssels 4 nicht der Länge des Kernstifts 10' entspricht. Da nun die Fläche 30 konisch ausgebildet ist, kann der Rotor 2 trotzdem weiter gedreht werden, wie dies in Figur 9 angedeutet ist. Der Rotor 2 hebt den Gehäusestift 29 an der konischen Fläche 30 an und bewegt diesen radial nach aussen. Die Fläche 30 kann wie bereits erwähnt auch kugelförmig oder ähnlich ausgebildet sein. Der Rotor 2 kann somit auch mit dem Schlüssel 4' über den Gehäusestift 29 hinausgedreht werden. Der Gehäusestift 29 bzw. die entsprechende Zuhaltung kann somit zwei Stufensprünge bedienen.In the FIG. 4 is the rotor 2 in the normal position. In the keyway 5, a key 4 'is used, which is characterized by the previous key 4 by a correspondingly less deep hole 9'. The housing pin 29 is correctly arranged here, so that the rotor 2 in the in FIG. 7 shown position is rotatable. The core pin 10 is now according to FIG. 7 at the height of the locking member 14. He arranges the locking member 14 as a conventional housing pin. The blocking member 14 thus does not lock and the rotor 2 can be rotated to open the lock, not shown here further clockwise. The FIG. 8 shows the rotary lock cylinder 1 in the same position as in FIG. 6 , but here in the key channel 5 of the key 4, ie thus the old key is inserted. As can be seen, the housing pin 29 with its end face 30 exceeds the dividing line T, since the bore 9 of the key 4 does not correspond to the length of the core pin 10 '. Since now the surface 30 is conical, the rotor 2 can still be rotated, as in FIG. 9 is indicated. The rotor 2 raises the housing pin 29 on the conical surface 30 and moves it radially outward. The surface 30 may, as already mentioned, also be spherical or similar. The rotor 2 can thus also be turned out with the key 4 'on the housing pin 29. The housing pin 29 or the corresponding tumbler can thus operate two increments.

Erreicht nun der Kernstift 10' das Sperrorgan 14, so wird dieses aktiv und sperrt den Rotor 2, wie dies in Figur 2 gezeigt ist. Da sich aufgrund der tieferen Bohrung 9 die in Figur 2 gezeigte Stirnfläche 13 des Kernstifts 10' im Abstand zur Trennfläche T befindet, kann das Sperrelement 15 vom Kernstift 10' nicht in der in Figur 1 gezeigten Stellung gehalten werden. Durch die Spannung der Feder 18 wird das Sperrelement 15 radial nach innen bewegt, bis der in Figur 1 gezeigte Abstand D zwischen den Fläche 21 und 22 aufgehoben ist. Der Abstand D ist etwas kleiner als ein Stufensprung, so dass die Führung des Sperrelements 15 aufgehoben ist, sobald dieses entsprechend einem Stufensprung radial nach innen bewegt wird. Das Sperrelement 15 löst sich damit vom Führungsteil 16 und liegt wie ersichtlich schräg in der Schieberbohrung 12 und teilweise in der Rotorbohrung 11.Now reaches the core pin 10 'the locking member 14, so this is active and locks the rotor 2, as in FIG. 2 is shown. Since due to the deeper hole 9 in FIG. 2 shown end face 13 of the core pin 10 'is located at a distance from the separation surface T, the blocking element 15 from the core pin 10' not in the in FIG. 1 shown position. Due to the tension of the spring 18, the blocking element 15 is moved radially inward until the in FIG. 1 shown distance D between the surface 21 and 22 is canceled. The distance D is slightly smaller than a step jump, so that the guidance of the locking element 15 is released as soon as it is moved radially inward according to a step jump. The blocking element 15 thus dissolves from the guide member 16 and As can be seen obliquely in the slide bore 12 and partially in the rotor bore eleventh

Das Sperrelement 15 sperrt den Rotor 2 und dieser kann nun weder im Uhrzeigersinn noch im Gegenuhrzeigersinn gedreht werden. Zudem kann das Sperrelement 15 nicht mehr radial nach aussen in das Führungsteil 16 eingeführt werden, da nun die Fläche 21 des Sperrelements 15 an der Fläche 22 des Führungsteils 16 anliegt. Da wie bereits oben erwähnt der Zwischenraum 31 zwischen dem Führungsteil 16 und dem Sperrelement 15 vergleichsweise schmal ist, genügt eine vergleichsweise kleine Verkantung des Sperrelements 15, um eine radiale Bewegung zu verhindern. Damit ist nicht nur der Rotor 2 blockiert, sondern auch der Kernstift 10', der radial nicht mehr bewegt werden kann. Der Schlüssel 4, bzw. der alte Schlüssel wird damit durch den Kernstift 10' festgehalten. Der Schlüssel 4 kann somit vom Drehschliesszylinder 1 nicht mehr abgezogen werden. Er ist damit gefangen.The blocking element 15 locks the rotor 2 and this can now be rotated neither clockwise nor counterclockwise. In addition, the blocking element 15 can no longer be introduced radially outwards into the guide part 16, since the surface 21 of the blocking element 15 now bears against the surface 22 of the guide part 16. Since, as already mentioned above, the gap 31 between the guide part 16 and the blocking element 15 is comparatively narrow, a comparatively small tilting of the blocking element 15 is sufficient to prevent a radial movement. This not only the rotor 2 is blocked, but also the core pin 10 ', which can not be moved radially. The key 4, or the old key is thus held by the core pin 10 '. The key 4 can thus not be deducted from the rotary lock cylinder 1. He is trapped with it.

Grundsätzlich ist ein Sperrorgan 14 in einem Drehschliesszylinder 1 ausreichend, um die genannte Funktion zu erfiillen. Es können im Schieber 7' aber auch hintereinander mehrere solche Sperrorgan 14 angeordnet sein. Zudem ist es gemäss Figur 10 möglich, in einem Drehschliesszylinder 1" noch weitere Schieber 7" und 7'" mit weiteren solchen Sperrorganen 14 vorzusehen.Basically, a blocking member 14 in a rotary locking cylinder 1 is sufficient to fulfill the said function. It can be arranged in the slide 7 'but also in succession a plurality of such blocking member 14. It is also according to FIG. 10 possible to provide in a rotary lock cylinder 1 "even more slide 7" and 7 '"with further such locking members 14.

Die Umstellung eines Drehschliesszylinders für eine Fangschliessung umfasst somit die folgenden drei Schritte.The conversion of a rotary lock cylinder for a catch closure thus comprises the following three steps.

Wenigstens ein Kernstift 10 wird durch einen kürzen Kernstift 10' ausgetauscht. Beispielsweise wird ein Dreier-Kernstift durch einen Zweier-Kernstift ersetzt.At least one core pin 10 is replaced by a shorter core pin 10 '. For example, a three-core pin is replaced with a two-core pin.

Der alte Schlüssel 4 wird durch einen neuen Schlüssel 4' ersetzt, bei dem im vorliegenden Fall die Dreierbohrung durch eine Zweierbohrung ersetzt ist.The old key 4 is replaced by a new key 4 ', in which the three-hole is replaced by a two-hole in the present case.

An entsprechender Stelle wird der Gehäusestift 29 eingesetzt, der mindestens einen Stufensprung ausgleichen kann. Dieser Gehäusestift 29 kann auch bereits vormontiert sein, so dass für die Umstellung auf eine Fangschaltung lediglich der Kernstift 10 durch den Kernstift 10' ersetzt und der neue Schlüssel 4' hergestellt werden muss. Die Umstellung auf eine Fangschliessung ist damit vergleichsweise einfach.At appropriate point of the housing pin 29 is used, which can compensate for at least one increment. This housing pin 29 can also be pre-assembled, so that for the switch to a catch circuit only the core pin 10 replaced by the core pin 10 'and the new key 4' must be made. The changeover to a catch closure is thus comparatively easy.

Das Sperrorgan 14 dient in diesem Fall zum Herstellen einer Fangschliessung. Das Sperrorgan 14 ist aber auch gegen zahlreiche Manipulationen, beispielsweise gegen die oben erwähnte Schlagtechnik äusserst wirksam. Es können in allen drei Schliessebenen eine oder mehrere solche Fangschliessungen angeordnet sein.The locking member 14 is used in this case for producing a catch closure. The blocking member 14 is also extremely effective against numerous manipulations, for example against the above-mentioned striking technique. It can be arranged in all three Schliessebenen one or more such catch closures.
