Description

Die Erfindung betrifft einen Profilzylinder mit einem Zylindergehäuse, einem drehbaren Zylinderkern, welcher einen Schlüsselkanal mit vorbestimmtem Profil aufweist, weiterhin mit schlüsselbetätigten Stiftzuhaltungen, die Innenstifte im Zylinderkern und Außenstifte im Zylindergehäuse aufweisen, sowie mit Stiftfedern im Zylindergehäuse, welche die Stiftzuhaltungen zum Schlüsselkanal hin vorspannen, gemäß Obergriff des Anspruchs 1.The invention relates to a profile cylinder with a cylinder housing, a rotatable cylinder core, which has a keyway with a predetermined profile, further with key-operated pin tumblers having inner pins in the cylinder core and outer pins in the cylinder housing, and with pin springs in the cylinder housing, which bias the pin tumblers towards the key channel, according to the preamble of claim 1.

Genormte Profilzylinder stellen Schließzylinder dar, die dazu bestimmt sind, austauschbar in vorgerichtete Schlösser, z.B. Einsteckschlösser nach DIN 18251 verwendet zu werden. Schlüssel für Profilzylinder werden in den Schlüsselkanal eingeschoben und weisen an ihrer Schlüsselbrust, die dem Schlüsselrücken gegenüberliegt, Einschnitte auf, die zum Ausrichten der im Profilzylinder vorgesehen Stiftzuhaltungen dienen. Die Einschnitte können auch als Einsenkungen realisiert sein. Ein zugangsberechtigter Schlüssel richtet die Stiftzuhaltungen so aus, dass diese mit einer Trennungsebene in der Umfangsfläche des Schließkerns stehen, so dass der Schließkern anschließend gedreht werden kann.Standardized profile cylinders represent lock cylinders designed to be interchangeable with pre-aligned locks, e.g. Mortise locks according to DIN 18251 to be used. Key for profile cylinder are inserted into the keyway and have on their key-breast, which is opposite to the key back, notches, which serve to align the pin tumblers provided in the profile cylinder. The cuts can also be realized as depressions. An access-authorized key aligns the pin tumblers so that they stand with a separation plane in the peripheral surface of the lock core, so that the lock core can then be rotated.

Das deutsche Gebrauchsmuster DE 20 2004 011 426 U1 zeigt einen Profilzylinder mit einem Gehäuse, welches ein kreiszylindrisches Teilgehäuse und darin einen mit einem Schlüsselkanal versehenen drehbaren Schließkern sowie ein an das kreiszylindrische Teilgehäuse angesetztes stegartiges Teilgehäuse aufweist. Im Gehäuse einerseits und im Schließkern andererseits sind miteinander in der Drehstellung des Schließkerns, welche der Schlüsselabziehstellung entspricht, fluchtende Teilbohrungen zur Unterbringung von in Richtung zum Schließkern federbelasteten Gehäuse- und Kernstiften vorgesehen. Weiterhin ist nach DE 20 2004 011 426 U1 eine in einer in der Radialebene besagter Teilbohrungen, aber seitlich daneben angeordnete Führungsbohrung vorgesehen. Gemäß der Aufgabenstellung der DE 20 2004 011 426 U1 soll eine unüberwindbare Blockierfunktion allein durch die konstruktive Gestaltung der Blockiereinrichtung erzielt werden.The German utility model DE 20 2004 011 426 U1 shows a profile cylinder with a housing having a circular cylindrical part housing and therein provided with a key channel rotatable lock core and attached to the circular cylindrical part housing web-like part housing. In the housing on the one hand and in the lock core on the other hand are aligned with each other in the rotational position of the lock core, which corresponds to the Schlüsselabziehstellung, partial holes provided to accommodate spring-loaded towards the lock core housing and core pins. Furthermore, after DE 20 2004 011 426 U1 one in a radial plane said partial bores, but laterally arranged next guide bore provided. According to the task of the DE 20 2004 011 426 U1 should an insurmountable blocking function can be achieved solely by the structural design of the blocking device.

Die dortige Aufgabe wird dadurch gelöst, dass die Blockiereinrichtung zwei voneinander baulich getrennte Teilelemente aufweist, die in der Führungsbohrung sitzend, ein Teilelement dem Schließkern zugewandt und das andere Teilelement vom Schließkern abgewandt, unter gegenseitiger Abstandsvergrößerung auseinander getrieben werden und mit dem Einfallen des dem Schließkern zugewandten Teilelements in eine gegenseitige Blockadeposition gelangen.The local object is achieved in that the blocking device has two structurally separate sub-elements, sitting in the guide bore, facing a partial element of the lock core and the other sub-element facing away from the lock core, are driven apart under mutual distance increase and facing the collapse of the lock core Subelement enter a mutual blocking position.

Die Blockadeposition wird dabei von einer Paarung aus gegenseitigen Anschlagflächen gebildet, von denen die eine mit dem einen Teilelement und die andere mit dem anderen Teilelement verbunden ist. Ab einem bestimmten Expansionsweg der vorgenannten Teilelemente liegen sich die Anschlagflächen so gegenüber, dass eine Einwärtsbewegung des dem Schließkern zugewandten Teilelements in die Führungsbohrung zurück ausgeschlossen werden kann. Der Sperranschlag wird zwischen den beiden Teilelementen durch eine Längsführung gebildet, die ab einem bestimmten Expansionsweg außer Eingriff gerät und dann wegversperrend in der Führungsbohrung ruht.The blocking position is formed by a pair of mutual abutment surfaces, one of which is connected to the one sub-element and the other to the other sub-element. From a certain expansion path of the aforementioned sub-elements, the abutment surfaces are opposite so that an inward movement of the closing core facing the sub-element can be excluded in the guide bore back. The blocking stop is formed between the two sub-elements by a longitudinal guide, which disengages from a certain expansion path and then rests wegperrperrend in the guide bore.

Das Dokument US 1 788 834 A offenbart einen Profilzylinder gemäss dem Oberbegriff des Anspruchs 1.The document US 1 788 834 A discloses a profile cylinder according to the preamble of claim 1.

Obwohl der vorbekannte Profilzylinder eine erhöhte Sicherheit gegen Manipulationen bietet, besteht konstruktiv keine Möglichkeit, insbesondere für Schließanlagen eine bedingte Schließung zu realisieren.Although the previously known profile cylinder provides increased security against manipulation, there is no constructive possibility, in particular for locking systems to realize a conditional closure.

Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, einen weiterentwickelten Profilzylinder mit einem Zylindergehäuse, einem drehbaren Zylinderkern, welcher einen Schlüsselkanal mit vorbestimmten Profil aufweist, und mit schlüsselbetätigten Stiftzuhaltungen anzugeben, welcher einen hohen Widerstand gegen Betätigung mit unberechtigtem Schlüssel bietet, der für verschiede Profilsysteme wie Flachschlüssel und Wendeschlüssel einsetzbar ist, welcher geringe Fertigungskosten aufweist und der letztendlich mit einem ersten Schlüssel eine begrenzte Schlüsseldrehung, z.B. zum Öffnen einer Schlossfalle, und mit einem zweiten Schlüssel eine vollständige Drehung gestattet, um Falle und Riegel eines Schlosses zu bewegen.From the foregoing, it is therefore an object of the invention to provide a further developed profile cylinder with a cylinder housing, a rotatable cylinder core, which has a keyway with a predetermined profile, and with key-operated pin tumblers, which provides a high resistance to operation with unauthorized key, for different profile systems as flat key and reversible key is used, which has low manufacturing costs and ultimately with a first key a limited key rotation, for example, to open a latch, and with a second key allows complete rotation to move latch and latch a lock.

Die Lösung der Aufgabe der Erfindung erfolgt durch einen Profilzylinder mit Zylindergehäuse und drehbarem Zylinderkern gemäß der Merkmalskombination nach Anspruch 1, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen darstellen.The object of the invention is achieved by a profile cylinder with a cylinder housing and rotatable cylinder core according to the combination of features according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.

Es wird demnach von einem Profilzylinder mit einem Zylindergehäuse, einem drehbaren Zylinderkern, welcher einen Schlüsselkanal mit vorbestimmtem Profil aufweist, und mit schlüsselbetätigten Stiftzuhaltungen ausgegangen, wobei die Stiftzuhaltungen Innenstifte im Zylinderkern und Außenstifte im Zylindergehäuse aufweisen. Weiterhin sind Stiftfedern im Zylindergehäuse vorhanden, welche die Stiftzuhaltungen zum Schlüsselkanal hin vorspannen.It is therefore assumed that a profile cylinder with a cylinder housing, a rotatable cylinder core, which has a keyway with a predetermined profile, and key-operated pin tumblers, the pin tumblers inner pins in the cylinder core and outer pins in the cylinder housing. Furthermore, pen springs are present in the cylinder housing, which bias the pin tumblers towards the key channel.

Erfindungsgemäß ist auf einem Axialabschnitt des Zylindergehäuses, mindestens in eine der Stiftzuhaltungen hineinreichend, ein hülsenförmiger Ring als Sperrelement angeordnet, welcher eine Sperrnase aufweist.According to the invention, a sleeve-shaped ring is arranged as a blocking element on an axial portion of the cylinder housing, reaching into at least one of the pin tumblers, which has a locking nose.

Weiterhin befindet sich im den Zylinderkern aufnehmenden Teilgehäuse eine Ausnehmung derart, welche den Drehbewegungsweg des hülsenförmigen Ringes bzw. des Sperrelements durch Inanschlagkommen mit der Sperrnase begrenzt.Furthermore, there is a recess in the cylinder core receiving part housing, which limits the rotational movement path of the sleeve-shaped ring or the locking element by Inanschlagkommen with the locking lug.

Darüber hinaus ist im hülsenförmigen Ring eine dem Durchmesser der jeweiligen Stiftzuhaltung entsprechende Bohrung oder Durchgangsöffnung befindlich, wobei je nach Tiefe der Codierung im zugehörigen Schlüssel entweder der hülsenförmige Ring mit dem Zylinderkern über die Stiftzuhaltung gekoppelt oder getrennt ist, so dass je nach eingesetztem Schlüssel und dessen Codierung nur ein begrenzter Drehwinkel von Schlüssel und Zylinderkern freigegeben ist.In addition, the diameter of the respective pin tumbler corresponding bore or through hole is located in the sleeve-shaped ring, depending on the depth of the coding in the associated key either the sleeve-shaped ring coupled to the cylinder core on the Stiftzuhaltung or is separated, so that depending on the inserted key and its Coding only a limited rotation angle of key and cylinder core is released.

Dieser begrenzte Drehwinkel dient beispielsweise dem Öffnen einer Schlossfalle.This limited angle of rotation serves, for example, to open a latch.

Liegt ein berechtigter Schlüssel vor, der eine vollständige Drehbewegung ermöglicht, können Schlossfalle und Riegel bewegt werden.If there is an authorized key that allows complete rotation, the latch and bolt can be moved.

Das vorstehend erläuterte Sperrelement, insbesondere ausgebildet als hülsenförmiger Ring, kann sowohl einseitig als auch beidseitig je nach Ausführungsform des Schließzylinders vorhanden sein.The above-described locking element, in particular formed as a sleeve-shaped ring, may be present both on one side and on both sides depending on the embodiment of the lock cylinder.

Die Ausnehmung, insbesondere ausgebildet als Freifräsung im Gehäuse, definiert den freigegebenen Drehwinkel. Denkbar sind hier z.B. Drehwinkel von 130° im Fall eines unberechtigten Schlüssels. Beim Einsatz eines berechtigten Schlüssels ist eine vollständige Drehbewegung um 360° gegeben.The recess, in particular designed as a free cut in the housing, defines the released angle of rotation. Conceivable here are e.g. Angle of rotation of 130 ° in the case of an unauthorized key. When using a legitimate key is given a complete rotation of 360 °.

Der begrenzte Drehwinkel ist durch das Maß der Ausnehmung und/oder die geometrische Gestalt der Sperrnase als Bestandteil des hülsenförmigen Ringes vorgebbar.The limited angle of rotation can be predetermined by the extent of the recess and / or the geometric shape of the locking lug as part of the sleeve-shaped ring.

Bei mechanischer Entkopplung von hülsenförmigem Ring und Zylinderkern liegt die Trennebene zwischen Zylinderkern und Zylindergehäuse, so dass Falle und Riegel eines entsprechenden Schlosses betätigbar sind.In mechanical decoupling of sleeve-shaped ring and cylinder core, the parting plane between the cylinder core and cylinder housing, so that the latch and bolt of a corresponding lock can be actuated.

Bei mechanischer Kopplung von hülsenförmigem Ring und Zylinderkern liegt die Trennebene zwischen hülsenförmigem Ring und Zylindergehäuse, so dass nur die Falle eines entsprechenden Schlosses betätigbar ist.In mechanical coupling of sleeve-shaped ring and cylinder core, the parting plane between sleeve-shaped ring and cylinder housing, so that only the case of a corresponding lock is actuated.

Zusammenfassend greift der erfindungsgemäße Profilzylinder mit Zylindergehäuse nebst zugehörigen Schlüsseln darauf zurück, dass in einer Ausnehmung im Gehäuse ein hülsenförmiger Ring als Sperrelement gelagert ist, welches eine Sperrnase besitzt. Das Sperrelement korrespondiert mit einem oder mehreren Innenstiften des Schließzylinders und den zugehörigen Codierungen im Schlüssel derart, dass je nach Tiefe bzw. Ausführung der zugehörigen Codierung im Schlüssel der oder die Innenstifte das Sperrelement mit dem Zylinderkern verbinden und beim Schließen mitnehmen. Die Sperrnase erlaubt die Drehung von Zylinderkern und Sperrelement nur über einen festgelegten Drehwinkel, welcher sich aus der Größe der vorerwähnten Ausnehmung ergibt.In summary, the profile cylinder according to the invention with cylinder housing together with associated keys is based on the fact that a sleeve-shaped ring is mounted as a blocking element in a recess in the housing, which has a locking lug. The blocking element corresponds to one or more inner pins of the lock cylinder and the associated codes in the key such that depending on the depth or execution of the associated coding in the key or the inner pins connect the locking element with the cylinder core and take along when closing. The locking lug allows the rotation of cylinder core and locking element only over a fixed angle of rotation, which results from the size of the aforementioned recess.

Gemäß Ausführungsbeispiel und den Figuren wird zunächst von einem Profilzylinder 1 mit einem Zylindergehäuse und einem drehbaren Zylinderkern 2 ausgegangen.According to the embodiment and the figures, it is initially assumed that a profile cylinder 1 with a cylinder housing and a rotatable cylinder core 2.

Der Zylinderkern 2 weist einen Schlüsselkanal 3 mit vorbestimmtem Profil auf. Weiterhin sind schlüsselbetätigte Stiftzuhaltungen vorhanden. Diese Stiftzuhaltungen umfassen Innenstifte 4 im Zylinderkern 2 und Außenstifte 5 im Zylindergehäuse 6.The cylinder core 2 has a key channel 3 with a predetermined profile. Furthermore, key-operated pin tumblers are present. These pin tumblers comprise inner pins 4 in the cylinder core 2 and outer pins 5 in the cylinder housing 6.

Darüber hinaus sind Stiftfedern 7 im Zylindergehäuse 6 befindlich, die die Stiftzuhaltungen zum Schlüsselkanal 2 hin vorspannen.In addition, pen springs 7 are located in the cylinder housing 6, which bias the pin tumblers to the keyway 2 out.

Auf einem Axialabschnitt des Zylinderkerns 2 bzw. im Zylindergehäuse 6 ist ein Sperrelement in Form eines hülsenförmigen Ringes 8 angeordnet.On an axial section of the cylinder core 2 or in the cylinder housing 6, a blocking element in the form of a sleeve-shaped ring 8 is arranged.

Der hülsenförmige Ring 8 reicht in mindestens eine der Stiftzuhaltungen hinein und weist eine Sperrnase 9 (siehe Fig. 3 und 4) auf.The sleeve-shaped ring 8 extends into at least one of the pin tumblers and has a locking lug 9 (see Fig. 3 and 4 ) on.

Aus den Schnittdarstellungen nach Fig. 1 und 2 ist erkennbar, dass das den Zylinderkern 2 aufnehmende Teilgehäuse 10 eine Ausnehmung besitzt, welche den Drehbewegungswinkel des hülsenförmigen Ringes 8 durch Inanschlagkommen mit der Sperrnase 9 begrenzt.From the sectional views to Fig. 1 and 2 can be seen that the cylinder core 2 receiving part housing 10 has a recess which limits the rotational movement angle of the sleeve-shaped ring 8 by Inanschlagkommen with the locking lug 9.

Die Schnittdarstellungen nach den Fig. 1 und 2 zeigen weiterhin eine Bohrung und eine Durchgangsöffnung im hülsenförmigen Ring 8. Diese Bohrung oder Durchgangsöffnung entspricht durchmesserseitig der jeweiligen Stiftzuhaltung 4, wobei je nach Tiefe der Codierung im zugehörigen Schlüssel 11 entweder der hülsenförmige Ring 8 mit dem Zylinderkern 2 gekoppelt oder getrennt ist, so dass je nach Schlüssel 11 und dortiger Codierung nur ein begrenzter Drehwinkel Y von Schlüssel 11 und Zylinderkern 2 freigegeben ist.The sectional views after the Fig. 1 and 2 This hole or through hole corresponds to the diameter side of the respective pin tumbler 4, wherein depending on the depth of the coding in the associated key 11 either the sleeve-shaped ring 8 is coupled to the cylinder core 2 or separated so that ever after key 11 and local coding only a limited angle of rotation Y of key 11 and cylinder core 2 is released.

Gemäß der Darstellung nach Fig. 1 weist der Schlüssel 11 im Bereich der Stiftzuhaltungen 4, die die entsprechenden Bohrungen im hülsenförmigen Ring 8 durchdringen, tiefe Ausnehmungen bzw. Bohrungen 12 auf. In diesem Fall liegt die Trennebene zwischen dem Zylinderkern 2 und dem Profilzylindergehäuse 6. Der entsprechende Schlüssel nebst Zylinderkern lässt sich vollständig, d.h. um 360° drehen, so dass Falle und Riegel eines zugehörigen Schlosses betätigt werden können.As shown Fig. 1 has the key 11 in the area of the pin tumblers 4, which penetrate the corresponding holes in the sleeve-shaped ring 8, deep recesses or holes 12. In this case, the dividing plane between the cylinder core 2 and the profile cylinder housing 6. The corresponding key and cylinder core can be completely, ie rotate by 360 °, so that the latch and bolt of an associated lock can be operated.

Bei der Darstellung nach Fig. 2 wird von flachen Bohrungen 13 in einem unberechtigten Schlüssel 11.1 ausgegangen.In the presentation after Fig. 2 is assumed by shallow holes 13 in an unauthorized key 11.1.

Die Fig. 3 und 4 mit im linken Bildteil dargestelltem Querschnitt durch den erfindungsgemäßen Profilzylinder lassen die Ausnehmung 14 im Profilzylindergehäuse nebst Sperrnase 9 erkennen. Die entsprechende Öffnung 14 im Gehäuse erstreckt sich über einen Winkelbereich X. Der Drehwinkel bei bedingter Schließung ist mit dem Bezugszeichen Y dargestellt. Die Schnittdarstellung im linken Bildteil entspricht dem Verlauf entlang der Linie C/C. Die Schnittdarstellung im linken Bildteil nach Fig. 4 entspricht dem Verlauf entlang der Linie E/E.The Fig. 3 and 4 with the illustrated in the left part of the cross section through the profile cylinder according to the invention let the recess 14 in the profile cylinder housing together with locking lug 9 recognize. The corresponding opening 14 in the housing extends over an angular range X. The rotation angle in case of conditional closure is represented by the reference symbol Y. The sectional view in the left part of the picture corresponds to the course along the line C / C. The sectional view in the left part of the picture after Fig. 4 corresponds to the course along the line E / E.

Durch eine Veränderung der Codiertiefe am jeweiligen Schlüssel lässt sich festlegen, ob eine Schlüsseldreh
ung begrenzt, z.B. im Bereich von 130° möglich ist oder ob eine vollständige Schlüsseldrehung um 360° erfolgen kann, um im letzteren Fall Falle und Riegel eines Schlosses zu bewegen.By changing the coding depth on the respective key can be determined whether a key turn
ung limited, for example in the range of 130 ° is possible or whether a complete turn of the key can be made by 360 °, in the latter case to move latch and bolt a lock.

Bei unberechtigtem Schlüssel 11.1 (siehe Fig. 2) reichen die betreffenden Innenstifte 4 durch Zylinderkern und Bohrung im hülsenförmigen Ring 8 mit der sich hieraus ergebenden Sperrebene zwischen dem hülsenförmigen Ring 8 und dem Profilzylindergehäuse 6. Der entsprechende Innenstift nimmt bei Drehbewegung den hülsenförmigen Ring 8 mit. Dessen Sperrnase stößt nach z.B. 130° an das Ende der entsprechenden Ausnehmung oder Ausfräsung im Zylindergehäuse 6. Eine weitere Drehung ist damit blockiert.For unauthorized key 11.1 (see Fig. 2 ), the respective inner pins 4 pass through cylinder core and bore in the sleeve-shaped ring 8 with the resultant locking plane between the sleeve-shaped ring 8 and the profile cylinder housing 6. The corresponding inner pin takes on rotation the sleeve-shaped ring 8 with. Its locking lug abuts after, for example 130 ° at the end of the corresponding recess or cutout in the cylinder housing 6. Another rotation is blocked.

Wird ein berechtigter Schlüssel 11 mit entsprechend tieferen Bohrungen eingesetzt, gehen die entsprechenden Innenstifte nur durch den Zylinderkern 2. Es ergibt sich damit eine Sperrebene wie in der Fig. 1 dargestellt. Der entsprechende Außenstift oder die vorgesehenen Außenstifte blockieren den hülsenförmigen Ring im Gehäuse. Damit nimmt der entsprechende Innenstift bei Drehbewegung den hülsenförmigen Ring nicht mit. Es wird also die Drehung nicht blockiert, so dass eine vollständige Schlüsseldrehung erfolgen kann und das Betätigen von Falle und Riegel eines Schlosses möglich wird.If an authorized key 11 is used with correspondingly deeper holes, the corresponding inner pins go only through the cylinder core 2. This results in a locking plane as in the Fig. 1 shown. The corresponding outer pin or outer pins block the sleeve-shaped ring in the housing. Thus, the corresponding inner pin does not take with rotary motion the sleeve-shaped ring. Thus, the rotation is not blocked, so that a complete turn of the key can be done and the operation of the latch and latch of a lock is possible.

Claims (6)

  1. A profiled cylinder (1), comprising a cylinder housing (6), a rotatable cylinder core (2) which has a keyway (3) with a predetermined profile, and further key-actuated pin tumblers which comprise inner pins (4) in the cylinder core (2) and outer pins (5) in the cylinder housing (6), and further comprising pin springs (7) in the cylinder housing (6) which pretension the pin tumblers towards the keyway (3), wherein a sleeve-shaped ring (8) is arranged in an axial section of the cylinder housing, reaching into at least one of the pin tumblers and having a locking lug (9), wherein a borehole or a through-opening which corresponds to the diameter of the respective pin tumbler is situated in the sleeve-shaped ring (8), wherein, depending on the depth of the encoding in the associated key (11; 11.1), the sleeve-shaped ring is either coupled to or separated from the cylinder core (2) via the pin tumbler, so that depending on the key (11; 11.1) and the encoding only a limited rotational angle of the key (11; 11.1) and the cylinder core (2) is released, characterized in that a recess (14) is disposed in the partial housing (10) accommodating the cylinder core (2), which recess limits the rotational movement path of the sleeve-shaped ring (8) by striking engagement with the locking lug (9).
  2. A profiled cylinder according to claim 1, characterized in that the limited rotational angle can be predetermined by the measure of the recess (14) and/or the geometric shape of the locking lug (9).
  3. A profiled cylinder according to claim 1 or 2, characterized in that a sleeve-shaped ring (8) is arranged on one side or both sides in the cylinder housing (6) or on the cylinder core (2).
  4. A profiled cylinder according to one of the preceding claims, characterized in that the recess (14) in the partial housing (10) is formed as a freely milled area.
  5. A profiled cylinder according to one of the preceding claims, characterized in that the separation plane is disposed between the cylinder core (2) and the cylinder housing (6) in the case of mechanical decoupling of the sleeve-shaped ring (8) and the cylinder core (2), so that the tumbler and the locking bolt of a lock can be actuated.
  6. A profiled cylinder according to one of the preceding claims, characterized in that the separation plane is disposed between the cylinder core (2) and the cylinder housing (6) in the case of mechanical coupling of the sleeve-shaped ring (8) and the cylinder core (2), so that only the tumbler of a lock can be actuated.
