Definitions
- the present invention relates to a lock cylinder comprising a rotatable cylinder core with a symmetrical key channel, which is suitable for receiving a reversible key.
- the present invention relates to a locking system with such a lock cylinder and with a key.
- the invention has for its object to enable a high variety of variants with reduced storage.
- lock cylinder with the features of claim 1. Thereafter, the lock cylinder is characterized in that adjacent to and in strictlyeinsteckides before the cylinder core an attachment element is arranged with an adjoining the key channel passage and that the passage is formed such that the keyway is partially covered by the attachment element.
- the passage may have an asymmetrical cross section.
- the symmetrical key channel is partially covered by the attachment element. A symmetrical reversible key can thus no longer be inserted into the key channel.
- the passage may have projections oriented in the key insertion direction at its edge regions, in particular at its edge regions which are located in the installed position.
- the attachment element may be formed as a profile disk.
- a flat design is realized, so that the overall length of the lock cylinder does not increase or only slightly.
- the passage may be adapted in its cross section to one of several possible key base profiles. This can increase the security against manipulation, since at most keys of a similar key base profile can be introduced into the lock cylinder. Already by providing several, in particular at least two, key base profiles, the security against manipulation can be increased.
- the manipulation safety can be increased again, since keys with the same profile base cross section can no longer be inserted into the lock cylinder, depending on the protrusions.
- the keyway can have a cross-sectionally round-cylindrical section and a substantially trapezoidal section which adjoins the round-cylindrical section with a narrow side. This allows a high key stability can be achieved. In addition, this embodiment provides space for a variety of tumblers.
- the keyway can have a further or second circular cylindrical section, which is partially covered by the attachment element.
- An asymmetrical section of a key can be received in this further or second cross-sectionally cylindrical section.
- further tumblers can be arranged here.

- These tumblers can be designed as Stiftzuness Herbertn with circumferentially more tumblers, the Stiftzuness Herbertn can be arranged on a circular arc, for example, a circular arc of about 300 °.
- further or second tumblers may be arranged in the cylinder core, which protrude into the further or second round cylindrical section. Manipulation is thus further complicated.
- the key shank may have a round cylindrical portion and a trapezoidal section in cross-section, which is connected at a narrow side with the round cylindrical portion. This creates a stable key profile.
- a variety of security features may be appropriate.
- recesses may be formed, which correspond with projections formed on the passage.
- These recesses which may also be referred to as longitudinal grooves, may be formed on broad sides of the trapezoidal section.
- profile cascades can be formed that match a corresponding shape of the passage of the attachment element.
- incisions for further tumblers can be formed in the trapezoidal section at a narrow side facing away from the round cylindrical section. This makes it possible to increase variant diversity and manipulation security.
- an active closing element can be arranged in the round cylindrical section.
- the active closing element can be designed as a ball, as a pin, as a magnet or as a roller.
- broad sides of the trapezoidal section may have an angled course with mutually parallel sections, a straight parallel course, a course with respective concave sections or a cross shape with laterally projecting struts.
- FIG. 1 shows a lock cylinder, which is designated by the reference numeral 10.

- the passage 20 has at its edge portions in Haitieinsteckraum 16 oriented projections 24 (only indicated here).
- the projections 24 prevent insertion of a key into the keyway 14 when the key is formed with its cross section not corresponding to the projections 24.
- tumblers 32 are arranged, which protrude into the - first - circular cylindrical portion 26 (only indicated here).
- the tumblers 32 are Stiftzuienss 1942n, which are arranged on a circular arc, for example, a circular arc of about three hundred degrees.
- further tumblers 34 are arranged, which protrude into the further or second round cylindrical section 30.
- the further tumblers 34 may be a pin tumbler row whose pins are arranged in the key insertion direction 16 on a straight line section.
- FIG. 2 shows a key 36 of a locking system 11.
- the key 36 has a key shaft 38 which is adapted in its cross section to the passage 20 so that the key shaft 38 is inserted through the passage 20 in the keyway 14.

Description
Die vorliegende Erfindung betrifft einen Schließzylinder umfassend einen drehbaren Zylinderkern mit einem symmetrischen Schlüsselkanal, der zur Aufnahme eines Wendeschlüssels geeignet ist. Zudem betrifft die vorliegende Erfindung ein Schließsystem mit einem solchen Schließzylinder und mit einem Schlüssel.The present invention relates to a lock cylinder comprising a rotatable cylinder core with a symmetrical key channel, which is suitable for receiving a reversible key. In addition, the present invention relates to a locking system with such a lock cylinder and with a key.
Aus dem Stand der Technik sind konventionelle Schließzylinder und Schlüssel sowie konventionelle Schließsysteme bekannt, beispielsweise aus der
Bei konventionellen Schlüsseln und Schließzylindern ist nachteilig, dass der Schlüssel lediglich in einer Position in den Schließzylinder eingeführt werden kann, wodurch die Handhabung beeinträchtigt ist. Wendeschlüssel und entsprechende Schließzylinder haben den Nachteil, dass die Variantenvielfalt an Schließmerkmalen auf Grund der symmetrischen Ausgestaltung eingeschränkt ist. Zur Fertigung der jeweiligen Schlüssel und Schließzylinder ist eine hohe Lagerhaltung erforderlich.In conventional keys and lock cylinders is disadvantageous that the key can be inserted only in one position in the lock cylinder, whereby the handling is impaired. Turnkey and corresponding lock cylinder have the disadvantage that the variety of types of locking features is limited due to the symmetrical design. For the production of the respective key and lock cylinder high storage is required.
Der Erfindung liegt die Aufgabe zugrunde, eine hohe Variantenvielfalt bei reduzierter Lagerhaltung zu ermöglichen.The invention has for its object to enable a high variety of variants with reduced storage.
Diese Aufgabe wird durch einen Schließzylinder mit den Merkmalen des Anspruchs 1 gelöst. Danach zeichnet sich der Schließzylinder dadurch aus, dass angrenzend an und in Schlüsseleinsteckrichtung vor dem Zylinderkern ein Aufsatzelement mit einem sich an den Schlüsselkanal anschließenden Durchgang angeordnet ist und dass der Durchgang derart ausgebildet ist, dass der Schlüsselkanal durch das Aufsatzelement teilweise abgedeckt ist.This object is achieved by a lock cylinder with the features of claim 1. Thereafter, the lock cylinder is characterized in that adjacent to and in Schlüsseleinsteckrichtung before the cylinder core an attachment element is arranged with an adjoining the key channel passage and that the passage is formed such that the keyway is partially covered by the attachment element.
Auf diese Weise kann eine hohe Variantenvielfalt bereitgestellt werden, wobei gleichzeitig die Anzahl vorzuhaltender Schließzylinderarten gering gehalten werden kann. So können mit lediglich einer Art an vorzuhaltenden Schließzylindern und Zylinderkernen verschiedene Schlossbauarten verwirklicht werden, nämlich herkömmliche Schließzylinder einerseits und Schließzylinder für Wendeschlüssel andererseits.In this way, a high variety of variants can be provided, while at the same time the number of locking cylinder types to be kept low can be kept. Thus, with only one type of locking cylinders to be kept and cylinder cores different types of locks can be realized, namely conventional lock cylinder on the one hand and lock cylinder for reversible key on the other.
Durch das Aufsatzelement, das auch als Profilaufsatz bezeichnet werden kann, wird der Schließzylinder mit einem Schlüsselkanal für Wendeschlüssel zu einem Schließzylinder ohne Wendefunktion. Das in axialer Richtung oder Schlüsseleinsteckrichtung vor dem Zylinderkern angeordnete Aufsatzelement weist einen sich an den Schlüsselkanal anschließenden Durchgang auf, der derart ausgebildet ist, dass der Schlüsselkanal durch das Aufsatzelement teilweise abgedeckt ist. Dies ermöglicht ein Einführen eines mit dem Durchgang korrespondierenden Schlüssels. Ein Wendeschlüssel, der ohne Aufsatzelement in den Zylinderkern passt, kann auf Grund des Aufsatzelements nicht mehr eingesteckt werden.By the attachment element, which can also be referred to as a profile attachment, the lock cylinder with a keyway for turning key to a lock cylinder without turning function. The attachment element arranged in the axial direction or key insertion direction in front of the cylinder core has a passage adjoining the key channel and formed in such a way that the keyway is partially covered by the attachment element. This allows insertion of a key corresponding to the passage. A reversible key that fits without attachment element in the cylinder core, can not be inserted due to the attachment element.
Das Aufsatzelement ist drehfest mit dem Zylinderkern gekoppelt. Aufsatzelement und Zylinderkern können bspw. miteinander verschweißt oder verpresst sein.The attachment element is rotatably coupled to the cylinder core. Attachment element and cylinder core can, for example, be welded or pressed together.
Im Weiteren ist von einem trapezförmigen Abschnitt die Rede. Dieser kann als im Wesentlichen quaderförmiger Abschnitt ausgebildet sein.In the following, we talk about a trapezoidal section. This can be designed as a substantially cuboidal section.
Im Konkreten kann der Durchgang einen asymmetrischen Querschnitt aufweisen. Somit ist der symmetrische Schlüsselkanal durch das Aufsatzelement teilweise abgedeckt. Ein symmetrischer Wendeschlüssel kann somit nicht mehr in den Schlüsselkanal eingeführt werden.Specifically, the passage may have an asymmetrical cross section. Thus, the symmetrical key channel is partially covered by the attachment element. A symmetrical reversible key can thus no longer be inserted into the key channel.
Alternativ oder zusätzlich kann der Durchgang eine kleinere Querschnittsfläche als der Schlüsselkanal aufweisen. Auch auf diese Weise ist ein Einführen eines symmetrischen Wendeschlüssels in den Schlüsselkanal durch das Aufsatzelement verhindert.Alternatively or additionally, the passage may have a smaller cross-sectional area than the keyway. Also in this way, insertion of a symmetrical reversible key into the keyway is prevented by the attachment element.
Zum Erhöhen der Variantenvielfalt kann der Durchgang an seinen Randbereichen, insbesondere an seinen in Einbaulage seitlichen Randbereichen, in Schlüsseleinsteckrichtung orientierte Vorsprünge aufweisen. Diese verhindern das Einführen eines Schlüssels in den Schlüsselkanal, falls der Schlüssel mit seinem Querschnitt nicht den Vorsprüngen entspricht, also nicht mit den Vorsprüngen des Durchgangs korrespondiert.In order to increase the variety of variants, the passage may have projections oriented in the key insertion direction at its edge regions, in particular at its edge regions which are located in the installed position. These prevent that Inserting a key in the keyway, if the key with its cross section does not correspond to the projections, so does not correspond to the projections of the passage.
Im Konkreten kann das Aufsatzelement als Profilscheibe ausgebildet sein. Somit ist eine flache Bauweise verwirklicht, so dass sich die Baulänge des Schließzylinders nicht oder nur unwesentlich erhöht.Specifically, the attachment element may be formed as a profile disk. Thus, a flat design is realized, so that the overall length of the lock cylinder does not increase or only slightly.
Im Konkreten kann der Durchgang in seinem Querschnitt an eines von mehreren möglichen Schlüsselgrundprofilen angepasst sein. Damit lässt sich die Manipulationssicherheit erhöhen, da allenfalls Schlüssel eines gleichartigen Schlüsselgrundprofils in den Schließzylinder eingeführt werden können. Bereits durch Bereitstellung mehrerer, insbesondere mindestens zwei, Schlüsselgrundprofile lässt sich die Manipulationssicherheit erhöhen.Concretely, the passage may be adapted in its cross section to one of several possible key base profiles. This can increase the security against manipulation, since at most keys of a similar key base profile can be introduced into the lock cylinder. Already by providing several, in particular at least two, key base profiles, the security against manipulation can be increased.
Zusammen mit den in Randbereichen des Durchgangs ausgebildeten Vorsprüngen lässt sich die Manipulationssicherheit abermals erhöhen, da auch Schlüssel mit gleichem Profilgrundquerschnitt je nach Vorsprüngen nicht mehr in den Schließzylinder eingeführt werden können.Together with the protrusions formed in the edge regions of the passage, the manipulation safety can be increased again, since keys with the same profile base cross section can no longer be inserted into the lock cylinder, depending on the protrusions.
Im Konkreten kann der Schlüsselkanal einen im Querschnitt rundzylindrischen Abschnitt und einen im Wesentlichen trapezförmigen Abschnitt aufweisen, der sich mit einer Schmalseite an den rundzylindrischen Abschnitt anschließt. Dadurch kann eine hohe Schlüsselstabilität erreicht werden. Zudem bietet diese Ausgestaltung Raum für eine Vielzahl an Zuhaltungen.In concrete terms, the keyway can have a cross-sectionally round-cylindrical section and a substantially trapezoidal section which adjoins the round-cylindrical section with a narrow side. This allows a high key stability can be achieved. In addition, this embodiment provides space for a variety of tumblers.
Zudem kann der Schlüsselkanal einen weiteren oder zweiten im Querschnitt rundzylindrischen Abschnitt aufweisen, der durch das Aufsatzelement teilweise abgedeckt ist. In diesem weiteren oder zweiten im Querschnitt rundzylindrischen Abschnitt kann ein asymmetrischer Abschnitt eines Schlüssels aufgenommen werden. Zudem können hier weitere Zuhaltungen angeordnet sein.In addition, the keyway can have a further or second circular cylindrical section, which is partially covered by the attachment element. An asymmetrical section of a key can be received in this further or second cross-sectionally cylindrical section. In addition, further tumblers can be arranged here.
Im Konkreten können im Zylinderkern Zuhaltungen angeordnet sein, die in den - ersten - rundzylindrischen Abschnitt hineinragen. Diese Zuhaltungen können als Stiftzuhaltungsreihen mit in Umfangsrichtung mehreren Zuhaltungen ausgebildet sein, wobei die Stiftzuhaltungsreihen auf einem Kreisbogen angeordnet sein können, beispielsweise einem Kreisbogen von ca. 300°.Concretely, tumblers may be arranged in the cylinder core, which protrude into the - first - round-cylindrical section. These tumblers can be designed as Stiftzuhaltungsreihen with circumferentially more tumblers, the Stiftzuhaltungsreihen can be arranged on a circular arc, for example, a circular arc of about 300 °.
Zur Erhöhung der Variantenvielfalt können im Zylinderkern weitere oder zweite Zuhaltungen angeordnet sein, die in den weiteren oder zweiten rundzylindrischen Abschnitt hineinragen. Eine Manipulation ist somit weiter erschwert.To increase the variety of variants further or second tumblers may be arranged in the cylinder core, which protrude into the further or second round cylindrical section. Manipulation is thus further complicated.
Die eingangs genannte Aufgabe wird auch mit einem Schließsystem mit den Merkmalen des nebengeordneten Patentanspruchs gelöst. Hinsichtlich der erfinderischen Tätigkeit wird auf das zum Anspruch 1 Gesagte verwiesen.The object mentioned above is also achieved with a locking system having the features of the independent claim. With regard to the inventive step, reference is made to what has been said for claim 1.
Zweckmäßigerweise kann der Schlüsselschaft einen rundzylindrischen Abschnitt und einen im Querschnitt trapezförmigen Abschnitt aufweisen, der an einer Schmalseite mit dem rundzylindrischen Abschnitt verbunden ist. Hiermit ist ein stabiles Schlüsselprofil geschaffen. Eine Vielfalt von Sicherheitsmerkmalen kann angebracht werden.Conveniently, the key shank may have a round cylindrical portion and a trapezoidal section in cross-section, which is connected at a narrow side with the round cylindrical portion. This creates a stable key profile. A variety of security features may be appropriate.
Im Konkreten können im trapezförmigen Abschnitt in Schlüssellängsrichtung orientierte Vertiefungen ausgebildet sein, die mit am Durchgang ausgebildeten Vorsprüngen korrespondieren. Diese Vertiefungen, die auch als Längsnuten bezeichnet werden können, können an Breitseiten des trapezförmigen Abschnitts ausgebildet sein. Somit können Profilkaskaden gebildet werden, die zu einer entsprechenden Form des Durchgangs des Aufsatzelements passen.Specifically, in the trapezoidal section in the key longitudinal direction oriented recesses may be formed, which correspond with projections formed on the passage. These recesses, which may also be referred to as longitudinal grooves, may be formed on broad sides of the trapezoidal section. Thus, profile cascades can be formed that match a corresponding shape of the passage of the attachment element.
In vorteilhafter Weise können im trapezförmigen Abschnitt an einer vom rundzylindrischen Abschnitt abgewandten Schmalseite Einschnitte für weitere Zuhaltungen ausgebildet sein. Damit lassen sich Variantenvielfalt und Manipulationssicherheit erhöhen.Advantageously, incisions for further tumblers can be formed in the trapezoidal section at a narrow side facing away from the round cylindrical section. This makes it possible to increase variant diversity and manipulation security.
Zur weiteren Erhöhung der Sicherheit kann im rundzylindrischen Abschnitt ein aktives Schließelement angeordnet sein. Das aktive Schließelement kann als Kugel, als Stift, als Magnet oder als Walze ausgebildet sein.To further increase the security, an active closing element can be arranged in the round cylindrical section. The active closing element can be designed as a ball, as a pin, as a magnet or as a roller.
In vorteilhafter Weise können Breitseiten des trapezförmigen Abschnitts einen angewinkelten Verlauf mit zueinander parallelen Abschnitten, einem geradlinig parallelen Verlauf, einen Verlauf mit jeweils konkaven Abschnitten oder eine Kreuzform mit seitlich abstehenden Streben aufweisen.Advantageously, broad sides of the trapezoidal section may have an angled course with mutually parallel sections, a straight parallel course, a course with respective concave sections or a cross shape with laterally projecting struts.
