Description

Die Erfindung betrifft einen Schlüssel zur Betätigung eines Schließzylinders, mit einer Schlüsselreide und einem sich von der Schlüsselreide erstreckenden Schlüsselschaft gemäß Oberbegriff von Anspruch 1. Zudem betrifft die Erfindung ein Schließsystem mit einem solchen Schlüssel und einem zugehörigen Schließzylinder.The invention relates to a key for actuating a locking cylinder, with a key lock and a key shaft extending from the key lock according to the preamble of claim 1. The invention also relates to a locking system with such a key and an associated locking cylinder.

Schlüssel sowie Schließsysteme der eingangs genannten Art sind aus dem Stand der Technik bekannt, bspw. aus der EP 2 388 415 A1 . Derartige Schlüssel weisen eine Schlüsselreide und einen sich von der Schlüsselreide erstreckenden Schlüsselschaft auf, an dem Ausnehmungen zum Ausrichten von Zuhaltungen ausgebildet sind, die an einem zugehörigen Schließzylinder vorgesehen sind. Derartige Schlüssel haben sich bewährt, da diese u.a. aufgrund der hohen Anzahl individueller Schließkombinationen für den Verbraucher eine hohe Sicherheit bieten.Keys and locking systems of the type mentioned are known from the prior art, for example from EP 2 388 415 A1 . Such keys have a key chalk and a key shaft extending from the key chalk, on which recesses for aligning tumblers are provided, which are provided on an associated locking cylinder. Keys of this type have proven themselves since, among other things, they offer a high level of security for the consumer due to the large number of individual locking combinations.

Allerdings besteht Raum für Optimierungen. So sind der Vorhalteaufwand sowie der Materialeinsatz bei der Herstellung entsprechender Schließzylinderschlüssel recht hoch. Zudem ist problematisch, dass sich durch die Verfügbarkeit moderner Kopierverfahren, bspw. unter Anwendung von 3D-Scannern und 3D-Druckern, auch vergleichsweise komplexe Schlüsselprofile erkennen und nachbilden lassen. Dies beeinträchtigt die gewünschte möglichst hohe Sicherheit für Endkunden. FR 2 492 872 A1 zeigt einen Schlüssel mit Merkmalen des Oberbegriffs von Anspruch 1.However, there is room for optimization. The maintenance effort and the use of materials in the production of corresponding locking cylinder keys are quite high. Another problem is that the availability of modern copying methods, for example using 3D scanners and 3D printers, also enables comparatively complex key profiles to be recognized and reproduced. This affects the desired high level of security for end customers. FR 2 492 872 A1 shows a key with features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Schlüssel bzw. einem Schließsystem mit einfachen konstruktiven Mitteln einen sicheren und zuverlässigen Betrieb zu ermöglichen. Dabei ist eine Reduktion des Materialeinsatzes wünschenswert.The invention has for its object to enable safe and reliable operation with a key or a locking system with simple design means. A reduction in the use of materials is desirable.

Die Erfindung löst die Aufgabe durch einen Schlüssel mit den Merkmalen des Anspruchs 1. Danach zeichnet sich der Schlüssel dadurch aus, dass im Schlüsselschaft ein sich durch den Schlüsselschaft hindurch erstreckender Kanal ausgebildet ist, in dem ein entlang oder innerhalb des Kanals verlagerbarer Wälzkörper zur Betätigung einer (seitlichen) Zuhaltung (eines Schließzylinders) angeordnet ist.The invention achieves the object by means of a key with the features of claim 1. According to this, the key is characterized in that a channel extending through the key shaft is formed in the key shaft, in which a rolling element displaceable along or within the channel for actuating a (Lateral) tumbler (a locking cylinder) is arranged.

Eine solche Ausgestaltung hat den Vorteil, dass die Kopiersicherheit eines derartigen Schlüssels (Schließzylinderschlüssel) erhöht ist. Dies ergibt sich daraus, dass mit modernen Kopierverfahren eine Schlüsselkontur relativ genau nachgebildet werden kann, nicht jedoch die Kinematik von beweglichen Elementen der Schlüsselkontur. Auch deren Funktion bezogen auf den zugehörigen Schließzylinder ist anhand des Schlüssels nicht erkennbar. Durch den in einem Kanal im Schlüsselschaft angeordneten Wälzkörper ist auch ein mechanisches Abtasten des Wälzkörpers erschwert, zumal der Wälzkörper im Kanal frei bewegbar sein kann. Auch dies trägt zur Kopiersicherheit bei. Auf Grund dieser Ausgestaltung können weitere neuartige Zuhaltungen bereitgestellt werden. Der Kopierschutz ist erhöht. Dabei kann mittels des Wälzkörpers eine Kraft durch den Schlüsselschaft hindurch geleitet werden. Durch den sich quer durch den Schlüsselschaft erstreckenden Kanal ist die Stabilität des Schlüsselschafts nicht oder nur in vernachlässigbarer Weise beeinträchtigt.Such an embodiment has the advantage that the copy security of such a key (cylinder lock key) is increased. This results from the fact that a key contour can be simulated relatively precisely with modern copying methods, but not the kinematics of moving elements of the Key outline. Their function in relation to the associated locking cylinder cannot be recognized from the key. The roller body arranged in a channel in the key shaft also makes mechanical scanning of the roller body more difficult, especially since the roller body can be freely movable in the channel. This also contributes to copy security. On the basis of this configuration, further novel tumblers can be provided. The copy protection is increased. A force can be passed through the key shaft by means of the rolling element. Due to the channel extending across the key shaft, the stability of the key shaft is not or only negligibly impaired.

Im Konkreten kann der Kanal für den Wälzkörper in der von der Schlüsselreide abgewandten Hälfte des Schlüsselschafts (vordere Schlüsselschafthälfte), insbesondere im vorderen Drittel des Schlüsselschafts, angeordnet sein. Dadurch kann eine mit dem Wälzkörper korrespondierende Zuhaltung an oder nahe dem innenliegenden Ende des Schließkanals eines zugehörigen Schließzylinders angeordnet sein. Dadurch sind Manipulationen erschwert.Specifically, the channel for the rolling element can be arranged in the half of the key shaft (front key shaft half) facing away from the key crayon, in particular in the front third of the key shaft. As a result, a tumbler corresponding to the rolling element can be arranged at or near the inner end of the locking channel of an associated locking cylinder. This makes manipulation difficult.

Im Konkreten kann der Kanal für den Wälzkörper an die Form des Wälzkörpers angepasst sein, so dass der Querschnitt des Kanals dem Querschnitt des Wälzkörpers entspricht. Dabei können die Innenabmessungen des Kanals insbesondere geringfügig größer gewählt sein als die Außenabmessungen des Wälzkörpers (Querschnitt bzw. Hauptabmessungen). Dies ermöglicht eine Bewegbarkeit des Wälzkörpers entlang des Kanals.In concrete terms, the channel for the rolling element can be adapted to the shape of the rolling element, so that the cross section of the channel corresponds to the cross section of the rolling element. The inner dimensions of the channel can in particular be selected to be slightly larger than the outer dimensions of the rolling element (cross section or main dimensions). This enables the rolling element to move along the channel.

Der Wälzkörper ist in seinen quer zum Schlüsselschaft (Schlüsselschaftstärke) orientierten Abmessungen geringer dimensioniert als die Stärke des Schlüsselschafts. Insbesondere weist der Wälzkörper bei einer kugelförmigen oder kreiszylindrischen Ausgestaltung einen Durchmesser auf, der geringer ist als die Stärke des Schlüsselschafts (Schlüsselschaftdicke). Bei kugelförmiger Ausgestaltung des Wälzkörpers kann der Kanal kreisförmig ausgebildet, bspw. gebohrt oder gestanzt, sein.The rolling element is smaller in its dimensions oriented transversely to the key shaft (key shaft strength) dimensioned as the strength of the key shaft. In particular, in the case of a spherical or circular cylindrical configuration, the rolling body has a diameter which is less than the thickness of the key shaft (key shaft thickness). In the case of a spherical configuration of the rolling element, the channel can be circular, for example drilled or punched.

Der Schlüsselschaft erstreckt sich insbesondere entlang einer Axialrichtung von der Schlüsselreide weg. Der Schlüssel weist insbesondere Schmalseiten auf, die entlang der Richtung der Stärke/Dicke des Schlüssels orientiert sind. Zwischen den Schmalseiten befindet sich insbesondere jeweils eine Seitenfläche des Schlüssels bzw. des Schlüsselschafts.The key shaft extends in particular along an axial direction away from the key chalk. The key has in particular narrow sides which are oriented along the direction of the thickness of the key. Between the narrow sides there is in particular one side surface of the key or of the key shaft.

Bei dem Schlüssel zur Betätigung eines Schließzylinders (Schließzylinderschlüssel) kann es sich insbesondere um einen Profilzylinderschlüssel handeln. Der zugehörige Schließzylinder kann insbesondere als Profilzylinder ausgebildet sein. "Zugehörig" bedeutet, dass ein Schlüssel passend in einen Schließzylinder eingesteckt werden kann, so dass der Schließzylinder durch den Schlüssel betätigt werden kann.The key for actuating a locking cylinder (locking cylinder key) can in particular be a profile cylinder key. The associated locking cylinder can in particular be designed as a profile cylinder. "Associated" means that a key can be inserted into a lock cylinder so that the lock cylinder can be actuated by the key.

Der Profilzylinderschlüssel kann als Bartschlüssel ("herkömmlicher Profilzylinderschlüssel") ausgebildet sein. Ein Bartschlüssel ist nur in einer Orientierung in einen zugehörigen Schließzylinder einsteckbar. Alternativ kann der Profilzylinderschlüssel als Wendeschlüssel ausgebildet sein. Ein Wendeschlüssel ist in mehreren, insbesondere in zwei, Orientierungen in einen zugehörigen Schließzylinder einsteckbar.The profile cylinder key can be designed as a beard key ("conventional profile cylinder key"). A beard key can only be inserted into an associated locking cylinder in one orientation. Alternatively, the profile cylinder key can be designed as a reversible key. A reversible key can be inserted into an associated locking cylinder in several, in particular two, orientations.

Im Rahmen einer bevorzugten Ausgestaltung kann der Kanal (Wälzkörperkanal) endseitig jeweils offen und endseitig im Querschnitt reduziert sein. Auf diese Weise kann der Wälzkörper abschnittsweise aus dem Kanal herausragen, ein Herausfallen des Wälzkörpers aus dem Kanal ist jedoch vermieden. Dadurch ist eine sichere Zuordnung des Wälzkörpers bezogen auf den Schlüsselschaft gewährleistet. Dabei kann der Kanal jeweils endseitig durch Umformung im Querschnitt reduziert sein. Bspw. kann der Wälzkörper im Schlüsselschaft verstemmt sein.In a preferred embodiment, the channel (rolling element channel) can be open at the end and reduced in cross-section at the end. In this way, the roller body can protrude in sections from the channel, but falling out of the roller body from the channel is avoided. This ensures a reliable assignment of the rolling element in relation to the key shank. The channel can in each case be reduced in cross section at the end by reshaping. E.g. the rolling element can be caulked in the key shaft.

In zweckmäßiger Weise kann sich der Kanal quer oder schräg durch den Schlüsselschaft hindurch erstrecken, insbesondere quer oder schräg zur Längsmittelebene des Schlüsselschafts angeordnet sein. Dadurch lässt sich eine Kraft auf kurzem Wege durch den Schlüsselschaft hindurch übertragen. Der Kanal kann den Schlüsselschaft insbesondere unter einem rechten Winkel schneiden (rechter Winkel zwischen Mittellängsachse des Kanals und der Mittellängsebene des Schlüsselschafts).The channel can expediently extend transversely or obliquely through the key shaft, in particular be arranged transversely or obliquely to the longitudinal center plane of the key shaft. This allows a force to be transmitted through the key shaft in a short way. The channel can in particular cut the key shaft at a right angle (right angle between the central longitudinal axis of the channel and the central longitudinal plane of the key shaft).

Im Konkreten kann der Wälzkörper als Kugel, Rolle oder Nadel ausgebildet sein. Hiermit kann ein für den jeweiligen Einsatzzweck geeigneter Wälzkörper bereitgestellt werden.In concrete terms, the rolling element can be designed as a ball, roller or needle. A rolling element suitable for the respective application can be provided in this way.

In vorteilhafter Weise kann zumindest an einer Seite des Schlüsselschafts eine Längsnut ausgebildet sein, die sich (axial) von dem Kanal bis zum freien Ende des Schlüsselschafts (Schlüsselschaftspitze) erstreckt. Hiermit ist ein einfaches Einführen des Schlüssels in einen Schlüsselkanal ermöglicht, insbesondere dann, wenn das zylinderseitige Anschlagelement bezogen auf den Schlüsselkanal oder den Zylinderkern des Schließzylinders ortsfest ausgebildet ist und/oder in den Schlüsselkanal hineinragt. Die Längsnut kann dann als Zugang für das vorstehende zylinderseitige Anschlagelement dienen.Advantageously, a longitudinal groove can be formed on at least one side of the key shaft, which extends (axially) from the channel to the free end of the key shaft (key shaft tip). This enables the key to be inserted easily into a key channel, in particular when the cylinder-side stop element is designed to be stationary with respect to the key channel or the cylinder core of the locking cylinder and / or into the key channel protrudes. The longitudinal groove can then serve as an access for the above cylinder-side stop element.

Weiter erfindungsgemäß weist der Schlüsselschaft in seiner von der Schlüsselreide axial abgewandten Hälfte (vordere Hälfte) einen Stabilisationseinsatz auf, der über eine höhere Festigkeit als das Material des Schlüsselschafts verfügt Dadurch wird der Schlüsselschaft verstärkt und stabilisiert. Das Risiko einer Beschädigung des Schlüsselschafts, bspw. durch Verbiegen oder Abbrechen, ist somit erheblich reduziert. Der Stabilisationseinsatz kann axial an der vom freien Ende des Schlüsselschafts abgewandten Seite des Kanals (Wälzkörperkanal) angeordnet sein.Furthermore, according to the invention, the key shaft has in its half axially facing away from the key bow (front half) a stabilizing insert which has a higher strength than the material of the key shaft. This strengthens and stabilizes the key shaft. The risk of damage to the key shaft, for example by bending or breaking off, is thus considerably reduced. The stabilizing insert can be arranged axially on the side of the channel (rolling element channel) facing away from the free end of the key shaft.

Im Konkreten kann der Stabilisationseinsatz in einem im Schlüsselschaft ausgebildeten, insbesondere gestanzten, Durchgang angeordnet, insbesondere eingepresst, sein. Zum Erreichen einer definierten Einpresstiefe kann innerhalb des Durchgangs eine Querschnittsreduzierung vorgesehen sein, bspw. in Form eines Absatzes. An dieser Querschnittsreduzierung kann der Stabilisationseinsatz in Anlage gelangen.In concrete terms, the stabilization insert can be arranged, in particular pressed, in a passage formed, in particular punched, in the key shaft. To achieve a defined press-in depth, a cross-sectional reduction can be provided within the passage, for example in the form of a shoulder. The stabilization insert can come into contact with this reduction in cross-section.

Im Rahmen einer möglichen Ausgestaltung kann der Stabilisationseinsatz derart ausgebildet sein, dass dieser bezogen auf die Seitenflächen des Schlüsselschafts bündig oder vertieft angeordnet ist. Alternativ hierzu ist denkbar, dass der Stabilisationseinsatz einseitig oder beidseitig jeweils einen aus dem Schlüsselschaft herausstehenden Vorsprung zur Schließcodierung aufweist.In the context of a possible embodiment, the stabilization insert can be designed such that it is arranged flush or recessed with respect to the side surfaces of the key shaft. As an alternative to this, it is conceivable for the stabilization insert to have a projection on one side or on both sides for locking coding that protrudes from the key shaft.

In vorteilhafter Weise können die Seitenflächen des Schlüsselschafts zueinander parallel und profilfrei ausgebildet sein (Seitenflächen frei von axialen, eine Schlüsselschaftprofilierung bildenden Vertiefungen und/oder Erhebungen). Dies erleichtert die Herstellung und reduziert die Lagerhaltung bei der Schlüsselherstellung, da stets auf das gleiche Grundmaterial zurückgegriffen werden kann. Dabei stellt die oben beschriebene Längsnut keine Profilierung des Schlüsselschafts dar, da diese lediglich eine Einführung eines Anschlagelements in den Kanal erleichtert. Der Querschnitt des Schlüsselschaftes selbst trägt somit nicht zur Schließcodierung bei, sondern lediglich die dem Schlüsselschaft einverleibten Merkmale, bspw. durch an in den Schlüsselschaft eingesetzten Einsätzen ausgebildete Vorsprünge und/oder durch im Schlüsselschaft ausgebildete (bartseitige) Ausnehmungen zur Betätigung von zylinderseitigen Zuhaltungen. Bei dem Grundmaterial zur Schlüsselherstellung kann es sich somit um unprofilierte Platten, bspw. Metall- oder Blechplatten, handeln.Advantageously, the side surfaces of the key shaft can be formed parallel to one another and free of profile (side surfaces free of axial depressions and / or elevations forming a key shaft profile). This simplifies production and reduces inventory during key production, since the same basic material can always be used. The longitudinal groove described above does not represent a profile of the key shaft, since this only facilitates the insertion of a stop element into the channel. The cross section of the key shaft itself therefore does not contribute to the locking coding, but rather only the features incorporated into the key shaft, for example by protrusions formed on inserts inserted into the key shaft and / or by recesses in the key shaft (beard side) for actuating cylinder-side tumblers. The base material for key production can thus be unprofiled plates, for example metal or sheet metal plates.

In vorteilhafter Weise kann der Schlüsselschaft zur Schließcodierung dienende Ausnehmungen (zur Betätigung zylinderseitiger Zuhaltungen) aufweisen und im Bereich der Ausnehmungen kann eine durchgehende Außenkante ausgebildet sein. Somit bilden die Ausnehmungen und die dazwischen befindlichen Erhebungen kein scharfkantiges Profil. Die Gefahr von Verletzungen an Schlüsselbenutzern und Beschädigung deren Kleidungsstücke ist somit reduziert. Die Ausnehmungen können auch als Einschnitte bezeichnet werden.In an advantageous manner, the key shaft can have recesses serving for locking coding (for actuating cylinder-side tumblers) and a continuous outer edge can be formed in the region of the recesses. Thus, the recesses and the elevations located between them do not form a sharp-edged profile. The risk of injuries to key users and damage to their clothing is thus reduced. The recesses can also be referred to as incisions.

Zweckmäßigerweise kann die Außenkante durch einen sich axial entlang des Schlüsselschafts erstreckenden Steg gebildet sein. Dieser bildet die stumpfe Außenkante und stabilisiert den Schlüsselschaft. Zu dem Steg können beidseitig die Ausnehmungen zur Schließcodierung angeordnet sein. Der Steg kann bezogen auf die Stärke des Schlüsselschaftes insbesondere mittig angeordnet sein, wobei sich der Steg zwischen den beiden Reihen von Ausnehmungen befindet und den Schlüsselschaft stabilisiert. Mit anderen Worten ist eine zweireihige Ausführung der Ausnehmungen mit Steg als zwischenliegendem Element geschaffen.The outer edge can expediently be formed by a web extending axially along the key shaft. This forms the blunt outer edge and stabilizes the key shaft. The recesses for locking coding can be arranged on both sides of the web. The web can be arranged in the middle in relation to the strength of the key shaft, the web being located between the two rows of recesses and stabilizing the key shaft. In other words, a two-row design of the recesses with a web as an intermediate element is created.

Im Konkreten kann der Schlüsselschaft, insbesondere die Schlüsselreide und der Schlüsselschaft, eine Materialstärke von 1,5mm bis 2,5mm (Millimeter), vorzugsweise 1,7mm bis 2,3mm, weiter vorzugsweise 1,8mm bis 2,2mm, noch weiter vorzugsweise 2,0mm, aufweisen.Specifically, the key shaft, in particular the key chalk and the key shaft, can have a material thickness of 1.5 mm to 2.5 mm (millimeters), preferably 1.7 mm to 2.3 mm, more preferably 1.8 mm to 2.2 mm, even more preferably 2 , 0mm.

Im Rahmen einer bevorzugten Ausgestaltung kann der Schlüssel aus nickelarmem Metall oder einer nickelarmen Metalllegierung, insbesondere aus einem nichtrostenden Chromstahl, ausgebildet sein. Somit können Allergien, die auf Seiten der Schlüsselbenutzer durch Kontakt mit einem Schließzylinderschlüssel entstehen können, vermieden werden. Dabei wird der Begriff "nickelarm" dahingehend verstanden, dass die Nickelabgabe unterhalb einer für Allergiker relevanten oder spürbaren Abgaberate liegt, insbesondere unterhalb von wöchentlich 0,5 µg Nickel pro cm2.In the context of a preferred embodiment, the key can be made from a low-nickel metal or a low-nickel metal alloy, in particular from a stainless chromium steel. This avoids allergies that can arise on the part of the key user through contact with a lock cylinder key. The term “low in nickel” is understood to mean that the release of nickel is below a release rate that is relevant or noticeable for allergy sufferers, in particular below 0.5 μg nickel per cm 2 per week.

Die eingangs genannte Aufgabe wird auch durch ein Schließsystem mit einem wie voranstehend beschriebenen Schlüssel und einem zugehörigen Schließzylinder mit den Merkmalen des nebengeordneten Anspruchs gelöst. Bei diesem Schließsystem handelt es sich insbesondere um eine Kombination bestehend aus dem Schlüssel wie oben beschrieben und einem zugehörigen Schließzylinder. Hinsichtlich der damit erzielbaren Vorteile sei auf die Ausführungen im Zusammenhang mit dem oben beschriebenen Schlüssel verwiesen.The above-mentioned object is also achieved by a locking system with a key as described above and an associated locking cylinder with the features of the independent claim. This locking system is in particular a Combination consisting of the key as described above and an associated locking cylinder. With regard to the advantages that can be achieved with this, reference is made to the explanations in connection with the key described above.

Das Schließsystem zeichnet sich dadurch aus, dass der Schließzylinder eine seitliche Zuhaltung zur Betätigung durch den verlagerbaren Wälzkörper des Schlüssels und an oder in seinem Schlüsselkanal (Schlüsselkanal des Schließkerns des Schließzylinders) ein Anschlagelement aufweist, wobei beim Einstecken des Schlüssels in den Schlüsselkanal der Wälzkörper mit dem Anschlagelement in Kontakt gelangt und dadurch im Kanal des Schlüsselschafts verlagert wird, wodurch die Zuhaltung in Freigabestellung verlagert wird.The locking system is characterized in that the locking cylinder has a side tumbler for actuation by the displaceable rolling element of the key and a stop element on or in its key channel (key channel of the locking core of the locking cylinder) Stop element comes into contact and is thereby shifted in the channel of the key shaft, whereby the guard locking is shifted to the release position.

Im Rahmen einer bevorzugten Ausgestaltung kann das Anschlagelement als ein orthogonal zum Schlüsselkanal im Zylinderkern angeordneter Stift (Abtaststift) ausgebildet sein. Hiermit ist ein konstruktiv einfaches und stabiles Anschlagelement geschaffen. Der Stift kann gestuft ausgebildet sein. Bspw. kann der Stift einen dem Schlüsselkanal zugewandten vorderen Abschnitt mit einem ersten Durchmesser und einen dem Schlüsselkanal abgewandten zweiten Durchmesser aufweisen, insbesondere wobei der zweite Durchmesser größer als der erste Durchmesser ist.In the context of a preferred embodiment, the stop element can be designed as a pin (scanning pin) arranged orthogonally to the key channel in the cylinder core. This creates a structurally simple and stable stop element. The pin can have a stepped design. E.g. For example, the pin can have a front section facing the key channel with a first diameter and a second diameter facing away from the key channel, in particular wherein the second diameter is larger than the first diameter.

Zur Erleichterung eines Einführens des Schlüssels kann das Anschlagelement bzw. der Stift ein dem Schließkanal zugewandtes konisches freies Ende (konische Spitze oder Kegelabschnitt) aufweisen. Der Stift kann bezogen auf den Schlüsselkanal und/oder den Zylinderkern ortsfest angeordnet sein. Der Stift kann auch als Aktivierungs-Abtaststift bezeichnet werden.To facilitate insertion of the key, the stop element or the pin can have a conical free end (conical tip or conical section) facing the locking channel. The pin can be fixed in relation to the key channel and / or the cylinder core be arranged. The pen can also be referred to as an activation stylus.

In vorteilhafter Weise kann die seitliche Zuhaltung im Durchmesserbereich des Zylindergehäuses (der einen Schließkern aufnehmende Abschnitt des Zylindergehäuses des Schließzylinders) angeordnet sein. Hiermit ist mit einfachen konstruktiven Mitteln eine seitliche Zuhaltung geschaffen. Die seitliche Zuhaltung kann einen Einpress-Stopfen, einen Sperrstift und eine Druckfeder aufweisen, die zwischen Einpressstopfen und Sperrstift angeordnet ist.The side tumbler can advantageously be arranged in the diameter range of the cylinder housing (the section of the cylinder housing of the locking cylinder that receives a locking core). A lateral guard locking is hereby created with simple constructive means. The side tumbler can have a press-in plug, a locking pin and a compression spring which is arranged between the press-in plug and the locking pin.

Zweckmäßigerweise kann im Zylinderkern des Schließzylinders ein Betätigungselement, insbesondere ein Betätigungsstift, angeordnet sein, über den der Wälzkörper auf die Zuhaltung wirkt. Hiermit ist mit einfachen Mitteln eine Übertragung einer Kraft vom Wälzkörper auf die seitliche Zuhaltung ermöglicht. Das Betätigungselement kann dem Anschlagelement bezogen auf den Schlüsselkanal gegenüberliegen. Insbesondere können die Längsachsen des Betätigungselements und des Anschlagelements parallel oder kongruent angeordnet sein.Appropriately, an actuating element, in particular an actuating pin, can be arranged in the cylinder core of the locking cylinder, via which the roller body acts on the tumbler. This enables simple transmission of a force from the rolling element to the side tumbler. The actuating element can lie opposite the stop element in relation to the key channel. In particular, the longitudinal axes of the actuating element and the stop element can be arranged in parallel or congruently.

Das Betätigungselement kann als Umlenkstift ausgebildet sein, das die Kraft mit einem seitlichen Versatz auf die Zuhaltung überträgt. Das Betätigungselement kann somit einen zylindrischen Abschnitt (Stiftabschnitt) und einen davon abragenden Armabschnitt aufweisen. Diese Ausgestaltung erlaubt eine versetzte Anordnung der seitlichen Zuhaltung bzw. deren Sperrstift bezogen auf das Anschlagelement und/oder den zylindrischen Abschnitt des Betätigungsstifts.The actuating element can be designed as a deflection pin which transmits the force to the tumbler with a lateral offset. The actuating element can thus have a cylindrical section (pin section) and an arm section projecting therefrom. This configuration allows an offset arrangement of the side tumbler or its locking pin in relation to the stop element and / or the cylindrical section of the actuating pin.

Die seitliche Zuhaltung, das Anschlagelement und/oder das Betätigungselement können (axial) an oder nahe des innenliegenden Endes des Schlüsselkanals angeordnet sein. Dadurch sind Manipulationen an diesen Komponenten erschwert.The side tumbler, the stop element and / or the actuating element can (axially) be arranged at or near the inner end of the key channel. This makes manipulation of these components difficult.

Der Schließzylinder kann weitere Merkmale aufweisen. So kann der Schließzylinder Zuhaltungen für Ausnehmungen im Schlüsselschaft aufweisen. Die Zuhaltungen können Kernstifte, Gehäusestifte und Federn (Zylinderfedern) zur Vorspannung der Zuhaltungen aufweisen. Stahlkugeln können die Öffnungen für die Zuhaltungen im Zylindergehäuse verschließen. Im Zylinderkern können benachbart zur Schließkanalöffnung Hartmetallstifte als Bohrschutz angeordnet sein. Der Schließzylinder kann eine zweireihige Ausgestaltung an Zuhaltungen und seitliche Zuhaltungen mit Profilabfragestiften aufweisen.The locking cylinder can have further features. The locking cylinder can thus have tumblers for recesses in the key shaft. The tumblers can have core pins, housing pins and springs (cylinder springs) for pretensioning the tumblers. Steel balls can close the openings for the tumblers in the cylinder housing. Tungsten carbide pins can be arranged in the cylinder core adjacent to the closing channel opening as drilling protection. The locking cylinder can have a two-row design of tumblers and lateral tumblers with profile query pins.

Zur weiteren Ausgestaltung des Schließsystems können auch die im Zusammenhang mit dem Schlüssel beschriebenen Maßnahmen dienen.The measures described in connection with the key can also be used to further develop the locking system.

Figur 1 zeigt eine Ausführungsform eines Schlüssels (Schließzylinderschlüssel), der insgesamt mit dem Bezugszeichen 10 bezeichnet ist. Der Schlüssel 10 ist vorliegend als "herkömmlicher Profilzylinderschlüssel" (Bartschlüssel) ausgebildet. Figure 1 shows an embodiment of a key (lock cylinder key), which is generally designated by the reference numeral 10. In the present case, the key 10 is designed as a “conventional profile cylinder key” (beard key).

Der Schlüssel 10 weist eine Schlüsselreide 12 und einen sich entlang einer Axialrichtung 14 von der Schlüsselreide 12 weg erstreckenden Schlüsselschaft 16 auf. Der Schlüsselschaft 16 weist eine axial von der Schlüsselreide 12 abgewandte Hälfte 18 (vordere Hälfte 18) und eine der Schlüsselreide 12 zugewandte Hälfte 20 (hintere Hälfte 20) auf.The key 10 has a key chalk 12 and a key shaft 16 which extends along an axial direction 14 away from the key chalk 12. The key shaft 16 has a half 18 (front half 18) axially facing away from the key spike 12 and a half 20 (rear half 20) facing the key spreader 12.

Im Schlüsselschaft 16 ist ein sich durch den Schlüsselschaft 16 hindurch erstreckender Kanal 22 ausgebildet. In dem Kanal 22 ist ein Wälzkörper 24 zur Betätigung einer seitlichen Zuhaltung eines zugehörigen Schließzylinders angeordnet (siehe Figur 3 und 4). Der Wälzkörper 24 ist entlang des Kanals 22 innerhalb des Kanals 22 verlagerbar. Der Wälzkörper 24 kann sich entlang des Kanals 22 frei bewegen.A channel 22 extending through the key shaft 16 is formed in the key shaft 16. A rolling element 24 for actuating a side tumbler of an associated locking cylinder is arranged in the channel 22 (see Figure 3 and 4th ). The rolling element 24 can be displaced along the channel 22 within the channel 22. The rolling element 24 can move freely along the channel 22.

Der Kanal 22 ist endseitig jeweils offen und (bezogen auf den zwischen den Enden befindlichen Kanalabschnitt) im Querschnitt reduziert (siehe Figur 4). Der Wälzkörper 24 kann endseitig abschnittsweise aus dem Kanal 22 herausragen, ein Herausfallen des Wälzkörpers 24 aus dem Kanal 22 ist jedoch vermieden. Der Wälzkörper 24 kann bspw. im Schlüsselschaft 16 verstemmt sein, wie vorliegend dargestellt.The channel 22 is open at the end and (in relation to the channel section located between the ends) reduced in cross section (see Figure 4 ). The rolling element 24 can protrude in sections from the end of the channel 22, but the rolling element 24 is prevented from falling out of the channel 22. The rolling element 24 can be caulked, for example, in the key shaft 16, as shown here.

Der Kanal 22 erstreckt sich quer durch den Schlüsselschaft 16 hindurch (Kanal 22 quer zur Längsmittelebene des Schlüsselschafts 16 angeordnet). Der Kanal 22 schneidet den Schlüsselschaft 16 insbesondere unter einem rechten Winkel.The channel 22 extends across the key shaft 16 (channel 22 arranged transversely to the longitudinal center plane of the key shaft 16). The channel 22 intersects the key shaft 16 in particular at a right angle.

Der Wälzkörper 24 ist vorliegend als Kugel ausgebildet. Der Kanal 22 weist einen kreisrunden Querschnitt auf und ist minimal größer ausgebildet als der Durchmesser des Wälzkörpers 24. Der Kanal 22 kann durch Bohren oder Stanzen ausgebildet sein.In the present case, the rolling element 24 is designed as a ball. The channel 22 has a circular cross section and is designed to be slightly larger than the diameter of the rolling element 24. The channel 22 can be formed by drilling or punching.

Der Schlüsselschaft 16 weist eine Seite 26 (Seitenfläche 27) und eine gegenüberliegende Seite 28 (Seitenfläche 29) auf (siehe Figur 1). An einer Seite 26 des Schlüsselschafts 16 ist eine Längsnut 30 ausgebildet, die sich axial von dem Kanal 22 bis zum freien Ende des Schlüsselschafts 16 (Schlüsselschaftspitze) erstreckt. Die Längsnut 30 dient als Zugang für ein zylinderseitiges Abtastelement, das den Wälzkörper 24 abtastet (weiter unten beschrieben).The key shaft 16 has a side 26 (side surface 27) and an opposite side 28 (side surface 29) (see Figure 1 ). A longitudinal groove 30 is formed on one side 26 of the key shaft 16 and extends axially from the channel 22 to the free end of the key shaft 16 (key shaft tip). The longitudinal groove 30 serves as an access for a cylinder-side scanning element, which scans the rolling element 24 (described below).

Der Schlüsselschaft 16 weist in seiner von der Schlüsselreide 12 axial abgewandten Hälfte 18 (vordere Hälfte 18) einen Stabilisationseinsatz 32 auf. Der Stabilisationseinsatz 32 verfügt über eine höhere Festigkeit als das Material des Schlüsselschafts 16. Der Stabilisationseinsatz 32 ist in einem im Schlüsselschaft 16 ausgebildeten Durchgang 33 befestigt, insbesondere eingepresst. Der Stabilisationseinsatz 32 ist derart ausgebildet, dass dieser im eingesetzten Zustand bezogen auf die Seitenflächen 27, 29 des Schlüsselschafts 16 bündig oder vertieft angeordnet ist.The key shaft 16 has a stabilizing insert 32 in its half 18 (front half 18) axially facing away from the key chalk 12. The stabilizing insert 32 has a higher strength than the material of the key shaft 16. The Stabilization insert 32 is fastened, in particular pressed, in a passage 33 formed in key shaft 16. The stabilizing insert 32 is designed such that it is arranged flush or recessed in the inserted state with respect to the side surfaces 27, 29 of the key shaft 16.

Die Seitenflächen 27, 29 des Schlüsselschafts 16 sind zueinander parallel und profilfrei ausgebildet. Dies bedeutet, dass die Seitenflächen 27, 29 frei von - eine Schlüsselschaftprofilierung bildenden -, bspw. axialen, Erhebungen und/oder Vertiefungen sind. Die oben beschriebene Längsnut 30 stellt keine Profilierung dar, da diese lediglich einer Einführung eines Abtastelements oder mit anderen Worten als Zugang für ein Anschlagelement in den Kanal 22 dient.The side surfaces 27, 29 of the key shank 16 are formed parallel to one another and without a profile. This means that the side surfaces 27, 29 are free of elevations and / or depressions, for example axial ones, which form a key shaft profile. The longitudinal groove 30 described above does not represent a profiling, since this only serves to introduce a scanning element or in other words as an access for a stop element into the channel 22.

Der Schlüsselschaft 16 weist zur Schließcodierung dienende Ausnehmungen 34, 36 auf (Einschnitte zur Betätigung von schlossseitigen Zuhaltungen 114). Im Bereich der Ausnehmungen 34, 36 ist eine durchgehende Außenkante 38 ausgebildet. Die Außenkante 38 ist durch einen sich axial entlang des Schlüsselschafts 16 erstreckenden Steg 40 gebildet. Beidseitig zum Steg 40 sind jeweils die Ausnehmungen 34, 36 angeordnet (zweireihige Ausgestaltung).The key shaft 16 has recesses 34, 36 serving for locking coding (incisions for actuating lock-side tumblers 114). A continuous outer edge 38 is formed in the area of the recesses 34, 36. The outer edge 38 is formed by a web 40 which extends axially along the key shaft 16. The recesses 34, 36 are arranged on both sides of the web 40 (double-row design).

Der Schlüssel 10, insbesondere die Schlüsselreide 12 und der Schlüsselschaft 16, können Materialstärken aufweisen wie oben beschrieben. Des Weiteren kann der Schlüssel 10 aus nickelarmem Metall oder einer nickelarmen Metalllegierung ausgebildet sein, wie oben beschrieben.The key 10, in particular the key chalk 12 and the key shaft 16, can have material thicknesses as described above. Furthermore, the key 10 can be formed from a low-nickel metal or a low-nickel metal alloy, as described above.

Figur 3 zeigt ein Schließsystem, welches insgesamt mit dem Bezugszeichen 100 bezeichnet ist. Das Schließsystem 100 weist einen Schlüssel 10 wie voranstehend beschrieben und einen zugehörigen Schließzylinder 102 auf. Der Schließzylinder 102 ist als "herkömmlicher Profilzylinder" zur Aufnahme eines Bartschlüssels ("herkömmlicher Profilzylinderschlüssel") ausgebildet. Figure 3 shows a locking system, which is designated overall by reference numeral 100. The locking system 100 has a key 10 as described above and an associated lock cylinder 102. The locking cylinder 102 is designed as a "conventional profile cylinder" for receiving a beard key ("conventional profile cylinder key").

Der Profilzylinder 102 weist ein Zylindergehäuse 104 auf, welches einen Durchmesserbereich 106 und einen taillierten Bereich 108 aufweist. Das Zylindergehäuse 104 kann einstückig oder modular ausgebildet sein (verschiedene Längen durch ein aus mehreren, unterschiedlich langen Elementen gebildetes Zylindergehäuse 104). Im Zylindergehäuse 104 ist ein Kerndurchgang 110 zur Aufnahme eines drehbaren Zylinderkerns 112 ausgebildet.The profile cylinder 102 has a cylinder housing 104 which has a diameter region 106 and a waisted region 108. The cylinder housing 104 can be formed in one piece or in a modular manner (different lengths by a cylinder housing 104 formed from several elements of different lengths). A core passage 110 for receiving a rotatable cylinder core 112 is formed in the cylinder housing 104.

Der Schließzylinder 102 weist Zuhaltungen 114 auf, die in Zuhaltungsbohrungen 116 in das Zylindergehäuse 104 bzw. den Zylinderkern 112 eingeführt werden. Die Zuhaltungen 114 weisen Gehäusestifte 118, Kernstifte 120 sowie Zylinderfedern 122 auf. Kugeln oder Stahlkugeln 124 verschließen die Zuhaltungsbohrungen 116 am in Figur 3 unteren Ende des Zylindergehäuses 104 (taillierter Bereich 108) .The locking cylinder 102 has tumblers 114 which are inserted into tumbler bores 116 in the cylinder housing 104 or the cylinder core 112. The tumblers 114 have housing pins 118, core pins 120 and cylinder springs 122. Balls or steel balls 124 close the tumbler holes 116 in Figure 3 lower end of the cylinder housing 104 (waisted area 108).

Der Zylinderkern 112 weist einen Schlüsselkanal 126 auf, in den der Schlüssel 10 von einem Einführende 128 eingeführt werden kann. Am Einführende 128 ist zu beiden Seiten des Schlüsselkanals 126 jeweils ein Bohrschutz 130 in Form eines Hartmetallstifts eingebracht. Die Hartmetallstifte 130 werden hierzu in Bohrschutzöffnungen 132 in den Zylinderkern 112 eingebracht.The cylinder core 112 has a key channel 126, into which the key 10 can be inserted by an introducer 128. A drill protection 130 in the form of a hard metal pin is inserted on each side of the key channel 126 at the introducer 128. For this purpose, the hard metal pins 130 are introduced into drilling protection openings 132 in the cylinder core 112.

Der Schließzylinder 102 weist eine seitliche Zuhaltung 134 zur Betätigung durch den verlagerbaren Wälzkörper 24 des Schlüssels 10 auf. Zudem weist der Zylinderkern 112 an oder in seinem Schlüsselkanal 126 ein Anschlagelement 136 auf. Die seitliche Zuhaltung 134 und das Anschlagelement 136 sind bezogen auf die Längsrichtung des Schlüsselkanals 126 axial auf gleicher Höhe angeordnet. Die seitliche Zuhaltung 134 und das Anschlagelement 136 liegen einander somit gegenüber.The locking cylinder 102 has a side tumbler 134 for actuation by the displaceable rolling element 24 of the Key 10 on. In addition, the cylinder core 112 has a stop element 136 on or in its key channel 126. The lateral tumbler 134 and the stop element 136 are arranged axially at the same height in relation to the longitudinal direction of the key channel 126. The lateral tumbler 134 and the stop element 136 are thus opposite one another.

Das Anschlagelement 136 ist als ein orthogonal zum Schlüsselkanal 126 im Zylinderkern 112 angeordneter Stift (Abtaststift) ausgebildet. Das Anschlagelement 136 ist in einer Anschlagelementaufnahmeöffnung 138 ortsfest im Zylinderkern 112 angeordnet. Das Anschlagelement 136 weist bezogen auf den Schlüsselkanal 126 einen vorderen Abschnitt 140 mit einem ersten Durchmesser und einen hinteren Abschnitt 142 mit einem zweiten Durchmesser auf, der größer als der erste Durchmesser ist. Das Anschlagelement 136 weist ein konisches vorderes Ende 144 auf, welches in den Schlüsselkanal 126 hineinragt.The stop element 136 is designed as a pin (scanning pin) arranged orthogonally to the key channel 126 in the cylinder core 112. The stop element 136 is arranged in a stop element receiving opening 138 in a stationary manner in the cylinder core 112. The stop element 136 has, with respect to the key channel 126, a front section 140 with a first diameter and a rear section 142 with a second diameter that is larger than the first diameter. The stop element 136 has a conical front end 144 which projects into the key channel 126.

Die seitliche Zuhaltung 134 ist im Durchmesserbereich 106 des Zylindergehäuses 104 angeordnet, und zwar in einer Ausnehmung 151 des Zylindergehäuses 104. Die seitliche Zuhaltung 134 weist einen Einpress-Stopfen 146 auf, der schalenförmig ausgebildet und zu einer Seite hin offen ist. In dieser Öffnung des Einpress-Stopfens 146 sind eine Druckfeder 148 und ein Sperrstift 150 angeordnet (siehe Figur 3 und 4).The side tumbler 134 is arranged in the diameter region 106 of the cylinder housing 104, specifically in a recess 151 of the cylinder housing 104. The side tumbler 134 has a press-in plug 146 which is bowl-shaped and is open on one side. A compression spring 148 and a locking pin 150 are arranged in this opening of the press-in plug 146 (see Figure 3 and 4th ).

In einer Ausnehmung 161 im Zylinderkern 112 des Schließzylinders 102 ist ein Betätigungselement 152 angeordnet, über welchen der Wälzkörper 24 (Kugel) auf die seitliche Zuhaltung 134 wirkt. Das Betätigungselement 152 kann auch als Betätigungsstift oder Umlenkstift bezeichnet werden. Im verriegelten Zustand grenzt das Betätigungselement 152 insbesondere bündig an den Schlüsselkanal 126.An actuating element 152 is arranged in a recess 161 in the cylinder core 112 of the locking cylinder 102, via which the rolling element 24 (ball) acts on the lateral tumbler 134. The actuating element 152 can also be referred to as an actuating pin or deflection pin will. In the locked state, the actuating element 152 borders in particular flush on the key channel 126.

Das Betätigungselement 152 weist einen zylindrischen Abschnitt 154 auf. Der zylindrische Abschnitt 154 kann einen bezogen auf den Schlüsselkanal 126 vorderen Bereich 156 mit geringerem Durchmesser und einen hinteren Bereich 158 mit größerem Durchmesser aufweisen. Das Betätigungselement 152 weist zudem einen vom zylindrischen Abschnitt 154 abragenden Armabschnitt 160 auf. Der Armabschnitt 160 ist mit dem Sperrstift 150 der seitlichen Zuhaltungen 134 in Kontakt. Der Armabschnitt 160 erlaubt eine versetze Anordnung der Zuhaltung 134 und des zylindrischen Abschnitts 154 des Betätigungselements.The actuating element 152 has a cylindrical section 154. The cylindrical section 154 can have a front area 156 with a smaller diameter in relation to the key channel 126 and a rear area 158 with a larger diameter. The actuating element 152 also has an arm section 160 projecting from the cylindrical section 154. The arm portion 160 is in contact with the locking pin 150 of the side tumblers 134. The arm section 160 allows an offset arrangement of the tumbler 134 and the cylindrical section 154 of the actuating element.

Die Funktion des Schließsystems 100 wird unter Bezugnahme auf Figur 4 erläutert.The function of the locking system 100 is described with reference to FIG Figure 4 explained.

Figur 4(a) zeigt einen verriegelten Zustand des Schließzylinders 102. Der Schlüssel 10 ist nicht in den Schlüsselkanal 126 eingesteckt. Figure 4 (a) shows a locked state of the lock cylinder 102. The key 10 is not inserted into the key channel 126.

Das Betätigungselement 152 ist unbetätigt, so dass die seitliche Zuhaltung 134 aktiv ist und eine Betätigung des Schließzylinders 102 sperrt. Der Sperrstift 150 ragt somit in den Zylinderkern 112 hinein. Selbst wenn sich die Zuhaltungen 114 in Freigabestellung befinden würden, könnte der Zylinderkern 112 relativ zum Zylindergehäuse 104 nur so weit gedreht werden, bis die Wandungsabschnitte 162, 164 am Sperrstift 150 anliegen. Eine zu einer Öffnung erforderliche vollständige Betätigung des Schließzylinders 102 ist nicht möglich.The actuating element 152 is not actuated, so that the side tumbler 134 is active and blocks actuation of the locking cylinder 102. The locking pin 150 thus protrudes into the cylinder core 112. Even if the tumblers 114 were in the release position, the cylinder core 112 could only be rotated relative to the cylinder housing 104 until the wall sections 162, 164 bear against the locking pin 150. A complete actuation of the locking cylinder 102 required for an opening is not possible.

Figur 4(b) zeigt einen entriegelten Zustand des Schließzylinders 102. Dabei ist der Schlüssel 10 in den Schließkanal 126 eingesteckt. Figure 4 (b) shows an unlocked state of the locking cylinder 102. The key 10 is inserted into the locking channel 126.

Beim Einstecken des Schlüssels 10 in den Schlüsselkanal 126 durchläuft das Anschlagelement 136 (konisches Ende 144) zunächst die im Schlüsselschaft 16 ausgebildete Längsnut 30, bevor der Wälzkörper 24 (Kugel) mit dem Anschlagelement 136 (konisches Ende 144) in Kontakt gelangt. Dabei ragt das Anschlagelement 136 mit seinem konischen Ende 144 in den im Schlüsselschaft 16 ausgebildeten Kanal 22 hinein und verlagert den Wälzkörper 24 entlang der Längsrichtung des Kanals 22 (in Figur 4 nach rechts). Der Wälzkörper 24 ragt dann an der vom Anschlagelement 136 abgewandten Seite des Schlüsselschafts 16 abschnittsweise heraus.When the key 10 is inserted into the key channel 126, the stop element 136 (conical end 144) first runs through the longitudinal groove 30 formed in the key shaft 16 before the rolling element 24 (ball) comes into contact with the stop element 136 (conical end 144). The conical end 144 of the stop element 136 projects into the channel 22 formed in the key shaft 16 and displaces the rolling element 24 along the longitudinal direction of the channel 22 (in Figure 4 to the right). The rolling element 24 then protrudes in sections on the side of the key shaft 16 facing away from the stop element 136.

Dadurch wird die seitliche Zuhaltung 134 in Freigabestellung verlagert. Indem der Wälzkörper 24 auf Grund des Kontakts mit dem Anschlagelement 136 aus dem Schlüsselschaft 16 herausragt, wird das Betätigungselement 152 entsprechend in Richtung der Zuhaltung 134 verlagert. Das vordere Ende des Sperrstifts 150 befindet sich somit in der Trennebene zwischen Zylinderkern 112 und Zylindergehäuse 104 (Rand des Kerndurchgangs) und damit in Freigabestellung. Sofern sich auch die Zuhaltungen 114 in Freigabestellung befinden, kann der Zylinderkern 112 bezogen auf das Zylindergehäuse 104 gedreht werden. Somit ist eine vollständige Betätigung des Schließzylinders 102 ermöglicht.As a result, the side tumbler 134 is shifted into the release position. Since the rolling element 24 projects out of the key shaft 16 due to the contact with the stop element 136, the actuating element 152 is correspondingly displaced in the direction of the tumbler 134. The front end of the locking pin 150 is thus in the parting plane between the cylinder core 112 and the cylinder housing 104 (edge of the core passage) and thus in the release position. If the tumblers 114 are also in the release position, the cylinder core 112 can be rotated in relation to the cylinder housing 104. This enables complete actuation of the locking cylinder 102.

Die Erfindung wurde im Zusammenhang mit einem als Bartschlüssel ("herkömmlicher Profilzylinderschlüssel") ausgebildeten Profilzylinderschlüssel und einem als "herkömmlichem Zylinder" ausgebildeten Profilzylinder beschrieben. Bei nicht dargestellten Ausführungsformen kann der Schlüssel als Profizylinderschlüssel in Form eines Wendeschlüssels und der Profilzylinder als Zylinder für einen solchen Wendeschlüssel ausgebildet sein. Der Schlüssel 10 kann dann an beiden Seiten 26, 28 eine Längsnut 30 aufweisen, die sich von der Spitze des Schlüsselschafts 16 bis zum Kanal 22 erstreckt.The invention was made in connection with a profile cylinder key designed as a beard key ("conventional profile cylinder key") and a profile cylinder designed as a "conventional cylinder" described. In embodiments not shown, the key can be designed as a professional cylinder key in the form of a reversible key and the profile cylinder as a cylinder for such a reversible key. The key 10 can then have a longitudinal groove 30 on both sides 26, 28, which extends from the tip of the key shaft 16 to the channel 22.
