Definitions
- the present invention relates to a lock cylinder according to the preamble of claim 1.
- Such a lock cylinder which is also referred to as a disk cylinder is, for example, in EP 0 712 979 B1 disclosed.
- Fig. 1 and 2 has a generic disc cylinder or lock cylinder 10, a cylinder housing 12 and a cylinder housing 12 rotatably mounted about a cylinder axis cylinder core 14.
- the rotational movement of the cylinder core 14 can be transmitted via a coupled with the cylinder core 14 coupling portion 30 to a locking mechanism of a lock, not shown.
- a plurality of rotatable tumbler discs 16 are added in succession along the cylinder axis.
- the tumbler discs 16 have respective central receiving openings 18 which together form a keyway 28 for insertion of a key 24 and which in the embodiment shown have a rectangular cross-section.
- the tumbler discs 16 also have respective circumferential recesses 20 for receiving a common locking pin 22 which is aligned parallel to the cylinder axis.
- the locking pin 22 is received radially movable in a slot 32 provided in the wall of the cylinder core 14.
- the locking pin takes a radially outer blocking position. In this blocking position engages a portion of the locking pin 22 in a provided on the inner wall of the cylinder housing 12 locking pin receptacle 34, so that the cylinder core 14 is blocked against rotation relative to the cylinder housing 12.
- the tumbler discs 16 can be transferred from their locking position into an unlocked position.
- the locking pin 22 can be displaced radially inwardly into its release position in which it is located outside the locking pin receptacle 34.
- the cylinder core 14 is released for rotational movement relative to the cylinder housing 12.
- the lock cylinder 10 associated key 24 has a plurality of different angled incisions 26, the different angular positions of the circumferential recesses 20 of the tumbler discs 22 correspond. After insertion into the keyway 28, the key 24 is rotated starting from a zero position in which the central receiving openings 18 are aligned with each other in the opening direction.
- the tumblers 16 have relative to the respectively associated cut 26 of the key 24 a certain backlash whose dimension depends on the angular extent of the respective incision 26, ie in response to the angular extent of the incisions 26 reach control sections of the respective cuts 26 and corresponding control sections the central receiving openings 18 of the associated respective tumbler discs 16 at different times or in different angular positions with each other.
- the entire rotational path of the key until reaching the unlocking position of all tumbler discs 16 is about 110 °, i.
- all tumbler discs 16 are sorted and aligned in radial alignment with the locking pin 22.
- a grid of six different angular positions is provided in a uniform pitch, wherein the angular distance between two adjacent circumferential recesses 20 is approximately 18 °. Accordingly, there are six possible codings for each tumbler 16, wherein for setting one of these codes the tumbler 16 are rotated by a certain angle from its zero position.
- a coding "1" is achieved after a rotation of the key 24 by about 20 °, an adjacent coding "2" after a rotation of about 38 °, etc., and finally a coding "6” after a Rotation of approx. 110 °, measured from zero position.
- the circumferential recesses 20 are accordingly arranged in an angular distance corresponding to the respective coding from the zero position.
- a positive coupling between the corresponding tumbler 16 and the associated portion of the key 24 may be provided, ie there is no incision or a cut with the angle 0 °, so that no backlash between the key 24 and the Tumbler 16 is.
- a tumbler 16 of the code "1" is thus basically only at the end of the rotary operation of the key 24, i. after a rotation of about 90 °, taken and brought by a turn of the key by another approx. 20 ° in its unlocked position.
- a generic lock cylinder also has one or more so-called lift discs, which are typically tumbler discs having the code "6" and provided in a predetermined axial position, e.g. with regard to the key insertion direction at the very front, at the very back or in the middle of the lock cylinder 10.
- the tumbler disc acting as lifting disc is positively coupled with the key. Based on the release position of the locking pin 22, the lifting disc ensures a key operation in the closing direction that the locking pin 22 is properly raised from the peripheral recesses 20 of the tumbler 16 and not tilted about.
- intermediate disks 36 between the tumbler disks 16, which are rotationally fixedly coupled to the cylinder core 14.
- the intermediate disks 36 decouple adjacent tumbler disks 16 from one another so that the rotational movement of a respective tumbler disk 16 does not cause co-rotation of the tumbler disk 16 adjacent thereto for reasons of friction. In fact, such a take-away could lead to a tumbler disk 16 possibly being rotated beyond its unlocking position, so that the lock cylinder 10 can no longer be opened.
- the rotationally fixed coupling of the intermediate disks 36 with the cylinder core can be effected by stop sections 40 of the intermediate disks 36 extending at least partially in the radial direction ( Fig. 2 ), which rest against corresponding, formed on the inner wall of the cylinder core 14 projections 42 without play.
- Each washer 36 has a peripheral cutout 38 which is radially aligned with the locking pin 22.
- the dimensions of the peripheral cutout 38 are adapted to the diameter of the locking pin 22, so that the intermediate discs 36 do not hinder displacement of the locking pin 22 in its release position.
- Lock cylinder of the type described above have proven to be advantageous tamper resistant. Nevertheless, an unauthorized person, with the aid of a suitable so-called picking tool, can try to scan the individual tumbler discs one after the other and thereby sort them one after the other, i. to bring in the respective unlocked position.
- intermediate plates according to the invention can be arranged not only between two mutually adjacent tumbler discs, but also at the very beginning or at the very end of the stack formed from the tumblers and washers, ie adjacent to an end face of the cylinder core.
- each of the codings is defined by a certain angular position of the circumferential recess of the tumbler with respect to the central receiving opening and the different codings are preferably provided with a uniform angular pitch and wherein the rotational play of the washers corresponds to the minimum angular distance between the locking position (ie the illustrated zero position) and the unlocking position of the tumbler discs for the different possible codes.
- the torsional backlash is as large as possible and corresponds thus at least the said minimum angular distance between the locking position and the unlocking position of the tumbler discs.
- the backlash is preferably not greater than the said minimum angular distance.
- each washer on its circumference on two stop portions, which cooperate to limit the torsional backlash of the washer with two corresponding stop portions on the inner circumference of the cylinder core.
- the distance of the stopper portions is increased from each other, so that in a modification of a conventional lock cylinder according to the invention a costly change to the cylinder core, in particular a displacement provided on the inner wall of the cylinder core Projections, not required.
- each washer has a peripheral cutout, which forms a receptacle for the locking pin in its release position, regardless of the angular position of the washer. This is particularly useful when the diameter of the intermediate discs is substantially equal to the diameter of the tumbler discs to nevertheless ensure displacement of the locking pin in its release position regardless of the angular position of the intermediate discs.
- the angular dimension of the peripheral cutout of the respective intermediate disks corresponds at least to the sum of the angular dimension of the peripheral recesses of the tumbler disks and the backlash of the respective intermediate disk.
- the key has a plurality of differently angled, a respective tumbler associated incisions, wherein the degree of bending of a respective incision of the coding of the associated tumbler corresponds to, and wherein upon rotation of the key in an open position each incision such cooperates with a corresponding control portion of the central receiving opening of the associated tumbler that each tumbler is rotated in its unlocked position.
- each washer is coupled by frictional engagement with the adjacent tumbler discs.
- This can be achieved in that the tumbler discs and the intermediate discs are biased in the axial direction to each other, for example by means of a spring.
- At least one tumbler disc designed as a lifting disc has a substantially backlash-free positive coupling of the control section with the corresponding recess of the key, and that the circumferential recess of the lifting disc has at least one run-on slope, which cooperates with the locking pin that at a rotation of the lifting disc is offset from its unlocking position into the locking position of the locking pin from its release position to its blocking position.
- the lift disc may be in any position relative to the cylinder axis.
- An inventive lock cylinder largely corresponds to the lock cylinder 10 according to Fig. 1 and 2 , which was already explained in detail at the beginning.
- This torsional backlash S is preferably chosen so that upon rotation of a tumbler 16 in the direction of its unlocking due to frictional engagement on the associated washer 136 adjacent tumbler 16 is taken only as far as there is a rotation of the tumbler 16 from its zero position to an angular position corresponds to the coding "1".
- the backlash S of the washers 136 should therefore be about 20 °, corresponding to the angular distance between the zero position and the angular position of the coding "1". It is understood that this specific angle for the backlash S refers to the lock cylinder 10 described above with the associated angular dimensions.
- the intermediate discs 136 may of course also have a different value of the torsional backlash S.
- the angular dimension of the respective peripheral cutouts 138 the intermediate discs 136 as compared to the angular extent of the peripheral cutouts 38 of the conventional intermediate discs 36 according to Fig. 2 also enlarged.
- Said angular extent of the peripheral cutouts 138 preferably corresponds to the sum of the angular dimension T of the peripheral recesses 20 of the tumbler discs 16 and the backlash S of the intermediate discs 136.

Description
Die vorliegende Erfindung betrifft einen Schließzylinder gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a lock cylinder according to the preamble of claim 1.
Ein derartiger Schließzylinder, welcher auch als Scheibenzylinder bezeichnet wird, ist beispielsweise in
Gemäß
In dem Zylinderkern 14 sind entlang der Zylinderachse hintereinander mehrere drehbare Zuhaltungsscheiben 16 aufgenommen. Die Zuhaltungsscheiben 16 besitzen jeweilige zentrale Aufnahmeöffnungen 18, welche gemeinsam einen Schlüsselkanal 28 zum Einführen eines Schlüssels 24 bilden und welche bei dem gezeigten Ausführungsbeispiel einen rechteckigen Querschnitt aufweisen. Die Zuhaltungsscheiben 16 besitzen ferner jeweilige Umfangsausnehmungen 20 zum Aufnehmen eines gemeinsamen Sperrstifts 22, welcher parallel zu der Zylinderachse ausgerichtet ist.In the
Der Sperrstift 22 ist radial beweglich in einem in der Wandung des Zylinderkerns 14 vorgesehenen Schlitz 32 aufgenommen. Wenn sich der Schließzylinder 10 in seiner Schließstellung befindet und damit die Zuhaltungsscheiben 16 in ihre Verriegelungsstellung gedreht sind, nimmt der Sperrstift eine radial äußere Blockierstellung ein. In dieser Blockierstellung greift ein Teilabschnitt des Sperrstifts 22 in eine an der Innenwandung des Zylindergehäuses 12 vorgesehene Sperrstiftaufnahme 34 ein, so dass der Zylinderkern 14 gegen eine Drehbewegung relativ zu dem Zylindergehäuse 12 blockiert ist.The
Mittels des Schlüssels 24 können die Zuhaltungsscheiben 16 von ihrer Verriegelungsstellung in eine Entriegelungsstellung überführt werden. Wenn sich alle Zuhaltungsscheiben 16 in ihrer Entriegelungsstellung befinden, d.h. wenn die Umfangsausnehmungen 20 aller Zuhaltungsscheiben 16 zueinander und radial zu dem Sperrstift 22 ausgerichtet sind, kann der Sperrstift 22 radial nach innen in seine Freigabestellung versetzt werden, in welcher er sich außerhalb der Sperrstiftaufnahme 34 befindet. Dadurch wird der Zylinderkern 14 für eine Drehbewegung relativ zu dem Zylindergehäuse 12 freigegeben.By means of the
Der dem Schließzylinder 10 zugeordnete Schlüssel 24 besitzt mehrere unterschiedlich abgewinkelte Einschnitte 26, die verschiedenen Winkelpositionen der Umfangsausnehmungen 20 der Zuhaltungsscheiben 22 entsprechen. Nach dem Einführen in den Schlüsselkanal 28 wird der Schlüssel 24 ausgehend von einer Nullstellung, in welcher die zentralen Aufnahmeöffnungen 18 zueinander ausgerichtet sind, in Öffnungsrichtung gedreht.The
Die Zuhaltungsscheiben 16 weisen gegenüber dem jeweils zugeordneten Einschnitt 26 des Schlüssels 24 ein bestimmtes Verdrehspiel auf, dessen Maß von dem Winkelmaß des jeweiligen Einschnitts 26 abhängt, d.h. in Abhängigkeit von dem Winkelmaß der Einschnitte 26 gelangen Steuerabschnitte der jeweiligen Einschnitte 26 und korrespondierende Steuerabschnitte der zentralen Aufnahmeöffnungen 18 der zugeordneten jeweiligen Zuhaltungsscheiben 16 zu unterschiedlichen Zeitpunkten bzw. in unterschiedlichen Winkelstellungen miteinander in Eingriff.The
Beispielsweise beträgt ausgehend von der Nullstellung der Zuhaltungsscheiben 16 der gesamte Rotationsweg des Schlüssels bis zum Erreichen der Entriegelungsstellung aller Zuhaltungsscheiben 16 ca. 110°, d.h. nach einer Drehung des Schlüssels 24 um ca. 110° sind alle Zuhaltungsscheiben 16 sortiert und in radialer Flucht zu dem Sperrstift 22 ausgerichtet. Typischerweise ist für die möglichen Winkelpositionen der Umfangsausnehmungen 20 ein Raster von sechs verschiedenen Winkelpositionen in gleichmäßiger Teilung vorgesehen, wobei der Winkelabstand zwischen zwei benachbarten Umfangsausnehmungen 20 ca. 18° beträgt. Entsprechend gibt es für jede Zuhaltungsscheibe 16 sechs mögliche Kodierungen, wobei zum Einstellen einer dieser Kodierungen die Zuhaltungsscheibe 16 um einen bestimmten Winkel aus ihrer Nullstellung verdreht werden. Bei dem beispielhaften Schließzylinder 10 wird eine Kodierung "1" nach einer Drehung des Schlüssels 24 um ca. 20° erreicht, eine benachbarte Kodierung "2" nach einer Drehung von ca. 38°, usw. und schließlich eine Kodierung "6" nach einer Drehung von ca. 110°, jeweils ab der Nullstellung gemessen. Die Umfangsausnehmungen 20 sind demgemäß in einem der jeweiligen Kodierung entsprechenden Winkelabstand von der Nullstellung angeordnet.For example, starting from the zero position of the
Bei der Kodierung "6" kann eine Zwangskopplung zwischen der entsprechenden Zuhaltungsscheibe 16 und dem zugeordneten Abschnitt des Schlüssels 24 vorgesehen sein, d.h. es ist kein Einschnitt bzw. ein Einschnitt mit dem Winkelmaß 0° vorhanden, so dass kein Verdrehspiel zwischen dem Schlüssel 24 und der Zuhaltungsscheibe 16 besteht.In the coding "6", a positive coupling between the
Bei der Kodierung "1" besteht hingegen das größtmögliche Verdrehspiel zwischen Schlüssel 24 und Zuhaltungsscheibe 16, d.h. an dem Schlüssel 24 ist ein Einschnitt 26 mit einem Winkelmaß von ca. 90° vorgesehen. Eine Zuhaltungsscheibe 16 der Kodierung "1" wird somit grundsätzlich erst am Ende der Drehbetätigung des Schlüssels 24, d.h. nach einer Drehung um ca. 90°, mitgenommen und durch eine Drehung des Schlüssels um weitere ca. 20° in ihre Entriegelungsstellung gebracht.In coding "1", however, there is the greatest possible backlash between key 24 and
Typischerweise besitzt ein gattungsgemäßer Schließzylinder auch eine oder mehrere so genannte Aushebescheiben, bei denen es sich in der Regel um Zuhaltungsscheiben handelt, die die Kodierung "6" aufweisen und die in einer vorbestimmten axialen Position vorgesehen ist, z.B. bezüglich der Schlüsseleinführrichtung ganz vorne, ganz hinten oder in der Mitte des Schließzylinders 10. Die als Aushebescheibe fungierende Zuhaltungsscheibe ist mit dem Schlüssel zwangsgekoppelt. Ausgehend von der Freigabestellung des Sperrstifts 22 stellt die Aushebescheibe bei einer Schlüsselbetätigung im Schließsinne sicher, dass der Sperrstift 22 ordnungsgemäß aus den Umfangsausnehmungen 20 der Zuhaltungsscheibe 16 angehoben wird und nicht etwa verkantet.Typically, a generic lock cylinder also has one or more so-called lift discs, which are typically tumbler discs having the code "6" and provided in a predetermined axial position, e.g. with regard to the key insertion direction at the very front, at the very back or in the middle of the
Ferner ist es üblich, zwischen den Zuhaltungsscheiben 16 Zwischenscheiben 36 anzuordnen, die mit dem Zylinderkern 14 drehfest gekoppelt sind. Die Zwischenscheiben 36 entkoppeln benachbarte Zuhaltungsscheiben 16 voneinander, damit die Drehbewegung einer jeweiligen Zuhaltungsscheibe 16 nicht reibungsbedingt ein Mitdrehen der hierzu benachbarten Zuhaltungsscheibe 16 bewirkt. Ein derartiges Mitnehmen könnte nämlich dazu führen, dass unter Umständen eine Zuhaltungsscheibe 16 über ihre Entriegelungsstellung hinaus verdreht wird und sich damit der Schließzylinder 10 nicht mehr öffnen lässt.Furthermore, it is customary to arrange
Die drehfeste Kopplung der Zwischenscheiben 36 mit dem Zylinderkern kann durch sich zumindest teilweise in radialer Richtung erstreckende Anschlagabschnitte 40 der Zwischenscheiben 36 erfolgen (
Jede Zwischenscheibe 36 weist einen Umfangsausschnitt 38 auf, der mit dem Sperrstift 22 radial fluchtet. Die Abmessungen des Umfangsausschnitts 38 sind an den Durchmesser des Sperrstifts 22 angepasst, so dass die Zwischenscheiben 36 ein Versetzen des Sperrstifts 22 in seine Freigabestellung nicht behindern.Each
Schließzylinder der vorstehend beschriebenen Art haben sich als vorteilhaft manipulationssicher erwiesen. Dennoch kann eine unbefugte Person unter Zuhilfenahme eines geeigneten, so genannten Picking-Werkzeugs versuchen, die einzelnen Zuhaltungsscheiben nacheinander abzutasten und hierdurch nacheinander zu sortieren, d.h. in die jeweilige Entriegelungsstellung zu bringen.Lock cylinder of the type described above have proven to be advantageous tamper resistant. Nevertheless, an unauthorized person, with the aid of a suitable so-called picking tool, can try to scan the individual tumbler discs one after the other and thereby sort them one after the other, i. to bring in the respective unlocked position.
Aus dem Dokument
Es ist die Aufgabe der Erfindung, einen Schließzylinder der eingangs genannten Art anzugeben, welcher eine verbesserte Manipulationssicherheit aufweist.It is the object of the invention to provide a lock cylinder of the type mentioned, which has an improved security against manipulation.
Die Lösung der Aufgabe erfolgt jeweils durch einen Schließzylinder mit den Merkmalen des Anspruchs 1 oder des Anspruchs 3.The object is achieved in each case by a lock cylinder having the features of claim 1 or claim 3.
Hierdurch wird also bewusst keine vollständige Entkopplung benachbarter Zuhaltungsscheiben relativ zueinander bewirkt. Stattdessen führt das Verdrehen einer Zuhaltungsscheibe, beispielsweise mittels eines Picking-Werkzeugs, dazu, dass auch eine hierzu benachbarte Zuhaltungsscheibe, die mittels des Picking-Werkzeugs eventuell bereits in ihre Entriegelungsstellung gebracht worden ist, durch Reibschluss neuerlich verdreht wird und somit unter Umständen wieder aus ihrer Entriegelungsstellung versetzt wird.As a result, therefore, no complete decoupling of adjacent tumbler discs is effected in a manner relative to one another. Instead, the rotation of a tumbler, for example by means of a picking tool, to the fact that even a tumbler adjacent thereto, which may have been brought by means of the picking tool already in its unlocked position is again rotated by frictional engagement and thus under certain circumstances again from their Unlocked position is offset.
Es versteht sich, dass die erfindungsgemäßen Zwischenscheiben nicht nur zwischen zwei zueinander benachbarten Zuhaltungsscheiben angeordnet werden können, sondern auch ganz am Anfang oder ganz am Ende des aus den Zuhaltungsscheiben und Zwischenscheiben gebildeten Stapels, also benachbart zu einer Stirnfläche des Zylinderkerns.It is understood that the intermediate plates according to the invention can be arranged not only between two mutually adjacent tumbler discs, but also at the very beginning or at the very end of the stack formed from the tumblers and washers, ie adjacent to an end face of the cylinder core.
Gemäß einem ersten Erfindungsaspekt ist vorgesehen, dass für die Zuhaltungsscheiben eine vorgegebene Anzahl von möglichen verschiedenen Kodierungen vorgesehen ist, wobei jede der Kodierungen durch eine bestimmte Winkelposition der Umfangsausnehmung der Zuhaltungsscheibe in Bezug auf die zentrale Aufnahmeöffnung definiert ist und die verschiedenen Kodierungen vorzugsweise in gleichmäßiger Winkelteilung vorgesehen sind, und wobei das Verdrehspiel der Zwischenscheiben dem minimalen Winkelabstand zwischen der Verriegelungsstellung (d.h. der erläuterten Nullstellung) und der Entriegelungsstellung der Zuhaltungsscheiben für die verschiedenen möglichen Kodierungen entspricht. Ein derartiges begrenztes Verdrehspiel verhindert wirksam ein Abtasten des Schlosses mittels eines Picking-Werkzeugs, ohne dass dabei die Gefahr besteht, dass bei ordnungsgemäßer Betätigung des Schließzylinders mittels des zugehörigen Schlüssels aufgrund von Reibschluss einzelne Zuhaltungsscheiben über ihre Entriegelungsstellung hinaus mitgenommen werden. Um im Hinblick auf die Picking-Sicherheit eine möglichst wirksame Kopplung zwischen zwei benachbarten Zuhaltungsscheiben durch Reibschluss zu erreichen, ist das Verdrehspiel möglichst groß gewählt und entspricht somit mindestens dem genannten minimalen Winkelabstand zwischen der Verriegelungsstellung und der Entriegelungsstellung der Zuhaltungsscheiben. Um die Zuhaltungsscheiben jedoch auch nicht unbeabsichtigt über ihre Entriegelungsstellung hinaus zu bewegen, ist das Verdrehspiel vorzugsweise auch wiederum nicht größer als der genannte minimale Winkelabstand.According to a first aspect of the invention, it is provided that a predetermined number of possible different codes are provided for the tumbler discs, wherein each of the codings is defined by a certain angular position of the circumferential recess of the tumbler with respect to the central receiving opening and the different codings are preferably provided with a uniform angular pitch and wherein the rotational play of the washers corresponds to the minimum angular distance between the locking position (ie the illustrated zero position) and the unlocking position of the tumbler discs for the different possible codes. Such a limited backlash effectively prevents scanning of the lock by means of a picking tool, without causing the risk that with proper operation of the lock cylinder by means of the associated key due to frictional individual tumblers are taken over their unlocking addition. In order to achieve the most effective coupling between two adjacent tumblers by frictional engagement with regard to the picking security, the torsional backlash is as large as possible and corresponds thus at least the said minimum angular distance between the locking position and the unlocking position of the tumbler discs. However, in order not to unintentionally move the tumbler disks beyond their unlocking position, the backlash is preferably not greater than the said minimum angular distance.
Bevorzugt weist jede Zwischenscheibe entlang ihres Umfangs zwei Anschlagabschnitte auf, welche zur Begrenzung des Verdrehspiels der Zwischenscheibe mit zwei korrespondierenden Anschlagabschnitten am Innenumfang des Zylinderkerns zusammenwirken. Gegenüber der eingangs beschriebenen herkömmlichen Zwischenscheibe, deren Anschlagabschnitte eine drehfeste Lagerung im Zylinderkern gewährleisten, ist hierbei der Abstand der Anschlagabschnitte voneinander vergrößert, so dass bei einer erfindungsgemäßen Modifikation eines herkömmlichen Schließzylinders eine kostenträchtige Veränderung am Zylinderkern, insbesondere ein Versetzen der an der Innenwandung des Zylinderkerns vorgesehenen Vorsprünge, nicht erforderlich ist. Dies ermöglicht es, einen herkömmlichen Schließzylinder mit drehfesten Zwischenscheiben auf einfache Weise mit den erfindungsgemäßen, drehspielbehafteten Zwischenscheiben nachzurüsten.Preferably, each washer on its circumference on two stop portions, which cooperate to limit the torsional backlash of the washer with two corresponding stop portions on the inner circumference of the cylinder core. Compared to the above-described conventional intermediate disc whose stop sections ensure a rotationally fixed bearing in the cylinder core, in this case the distance of the stopper portions is increased from each other, so that in a modification of a conventional lock cylinder according to the invention a costly change to the cylinder core, in particular a displacement provided on the inner wall of the cylinder core Projections, not required. This makes it possible to retrofit a conventional lock cylinder with rotatable intermediate washers in a simple manner with the inventive, drehspielbehafteten washers.
Gemäß einem zweiten Erfindungsaspekt weist jede Zwischenscheibe einen Umfangsausschnitt auf, welcher unabhängig von der Winkelstellung der Zwischenscheibe eine Aufnahme für den Sperrstift in seiner Freigabestellung bildet. Dies ist insbesondere dann sinnvoll, wenn der Durchmesser der Zwischenscheiben im Wesentlichen gleich dem Durchmesser der Zuhaltungsscheiben ist, um gleichwohl ein Versetzen des Sperrstifts in seine Freigabestellung unabhängig von der Winkelposition der Zwischenscheiben zu gewährleisten.According to a second aspect of the invention, each washer has a peripheral cutout, which forms a receptacle for the locking pin in its release position, regardless of the angular position of the washer. This is particularly useful when the diameter of the intermediate discs is substantially equal to the diameter of the tumbler discs to nevertheless ensure displacement of the locking pin in its release position regardless of the angular position of the intermediate discs.
Hierbei entspricht das Winkelmaß des Umfangsausschnitts der jeweiligen Zwischenscheiben zumindest der Summe aus dem Winkelmaß der Umfangsausnehmungen der Zuhaltungsscheiben und dem Verdrehspiel der jeweiligen Zwischenscheibe.In this case, the angular dimension of the peripheral cutout of the respective intermediate disks corresponds at least to the sum of the angular dimension of the peripheral recesses of the tumbler disks and the backlash of the respective intermediate disk.
Gemäß einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass der Schlüssel mehrere unterschiedlich abgewinkelte, einer jeweiligen Zuhaltungsscheibe zugeordnete Einschnitte aufweist, wobei das Maß der Abwinkelung eines jeweiligen Einschnitts der Kodierung der zugeordneten Zuhaltungsscheibe entspricht, und wobei bei einem Verdrehen des Schlüssels in eine Öffnungsstellung jeder Einschnitt derart mit einem korrespondierenden Steuerabschnitt der zentralen Aufnahmeöffnung der zugeordneten Zuhaltungsscheibe zusammenwirkt, dass jede Zuhaltungsscheibe in ihrer Entriegelungsstellung verdreht wird.According to a further preferred embodiment it is provided that the key has a plurality of differently angled, a respective tumbler associated incisions, wherein the degree of bending of a respective incision of the coding of the associated tumbler corresponds to, and wherein upon rotation of the key in an open position each incision such cooperates with a corresponding control portion of the central receiving opening of the associated tumbler that each tumbler is rotated in its unlocked position.
Bevorzugt ist jede Zwischenscheibe durch Reibschluss mit den benachbarten Zuhaltungsscheiben gekoppelt. Dies kann dadurch erreicht werden, dass die Zuhaltungsscheiben und die Zwischenscheiben in axialer Richtung zueinander vorgespannt sind, beispielsweise mittels einer Feder.Preferably, each washer is coupled by frictional engagement with the adjacent tumbler discs. This can be achieved in that the tumbler discs and the intermediate discs are biased in the axial direction to each other, for example by means of a spring.
Gemäß einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass zumindest eine als Aushebescheibe ausgebildete Zuhaltungsscheibe eine im Wesentlichen spielfreie Zwangskopplung des Steuerabschnitts mit dem korrespondierenden Einschnitt des Schlüssels aufweist, und dass die Umfangsausnehmung der Aushebescheibe zumindest eine Anlaufschräge aufweist, welche derart mit dem Sperrstift zusammenwirkt, dass bei einem Verdrehen der Aushebescheibe von ihrer Entriegelungsstellung in die Verriegelungsstellung der Sperrstift von seiner Freigabestellung in seine Blockierstellung versetzt wird. Die Aushebescheibe kann sich in beliebiger Position in Bezug auf die Zylinderachse befinden.According to a further preferred embodiment, it is provided that at least one tumbler disc designed as a lifting disc has a substantially backlash-free positive coupling of the control section with the corresponding recess of the key, and that the circumferential recess of the lifting disc has at least one run-on slope, which cooperates with the locking pin that at a rotation of the lifting disc is offset from its unlocking position into the locking position of the locking pin from its release position to its blocking position. The lift disc may be in any position relative to the cylinder axis.

Dieses Verdrehspiel S ist dabei vorzugsweise so gewählt, dass beim Verdrehen einer Zuhaltungsscheibe 16 in Richtung ihrer Entriegelungsstellung aufgrund von Reibschluss über die zugeordnete Zwischenscheibe 136 eine benachbarte Zuhaltungsscheibe 16 nur soweit mitgenommen wird, wie es einem Verdrehen der Zuhaltungsscheibe 16 von ihrer Nullstellung in eine Winkelposition mit der Kodierung "1" entspricht. Für eine Verwendung mit dem eingangs beschriebenen Schließzylinder 10 sollte das Verdrehspiel S der Zwischenscheiben 136 demnach etwa 20° betragen, entsprechend dem Winkelabstand zwischen der Nullstellung und der Winkelposition der Kodierung "1". Es versteht sich, dass sich diese konkrete Winkelangabe für das Verdrehspiel S auf den eingangs beschriebenen Schließzylinder 10 mit den zugehörigen Winkelmaßen bezieht. Für andere Winkelmaße und Kodierungsraster können die Zwischenscheiben 136 selbstverständlich auch einen anderen Wert des Verdrehspiels S aufweisen.This torsional backlash S is preferably chosen so that upon rotation of a
