Description

Die Erfindung betrifft ein Zylinderschloss-Schließsystem mit einem Wendeschlüssel dieser mit Schlüsselreide und Schlüsselbart, wobei der Schlüsselbart eine Vielzahl von rotationssymmetrischen Vertiefungen zur Aufnahme von stiftartigen Zuhaltungen eines Schließzylinders aufweist, wobei die stiftartigen Zuhaltungen als klassische zweiteilige Reihenanordnung im Schließzylindergehäuse sowie im Zylinderkern ausgeführt sind, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a cylinder lock system with a reversible key this with key and key bit, wherein the key bit has a plurality of rotationally symmetrical depressions for receiving pin-like tumblers of a lock cylinder, wherein the pin-like tumblers are designed as a classic two-part arrangement in the lock cylinder housing and in the cylinder core, according to the preamble of claim 1.

Die WO 2004/011745 A1 betrifft einen Wendeschlüssel mit dort vorgesehenen weiteren Codiermöglichkeiten in Form von durch Prägung ausgebildeten Steuerflächen. Diese Steuerflächen besitzen eine rechteckige Bodenfläche.The WO 2004/011745 A1 relates to a reversible key with there provided further Codiermöglichkeiten in the form of formed by embossing control surfaces. These control surfaces have a rectangular bottom surface.

Aus der US 5,682,779 ist ein System aus Schlüssel und Zylinderschloss vorbekannt, welches weitere Kodiermöglichkeiten und eine höhere Sicherheit schaffen soll.From the US 5,682,779 is a system of key and cylinder lock previously known, which should provide more coding options and greater security.

Dies wird dadurch erreicht, dass im Schlüssel Schlitze vorgesehen sind, welche mit Stiften im Zylinder korrespondieren, die eine prismatische Form besitzen und mit ihrer Oberseite in die jeweiligen Schlitze eingreifen.This is achieved by providing in the key slots which correspond to pins in the cylinder, which have a prismatic shape and engage with their upper side in the respective slots.

Die Schlitze im Schlüssel können einerseits auf der Längsachse liegen bzw. parallel zu dieser angeordnet sein, aber auch ganz unterschiedliche Winkelorientierungen besitzen. Konkret wird diesbezüglich auf Winkel im Bereich zwischen 0° bis 360° verwiesen. Bei einer bevorzugten Ausgestaltung der Lösung nach US 5,682,779 ist die Winkelposition einstellbar gestaltet, um auch kundenseitig eine individuelle Kodierung vornehmen zu können. Bei einer weiteren Ausführungsvariante sind die Winkel und die Position der einzelnen Schlitze bereits herstellerseitig fest vorgegeben.The slots in the key can either lie on the longitudinal axis or be arranged parallel to it, but also have very different angular orientations. Specifically, in this regard, reference is made to angles in the range between 0 ° to 360 °. In a preferred embodiment of the solution according to US 5,682,779 the angular position is designed adjustable so that the customer can also make an individual coding. In a further embodiment, the angle and the position of the individual slots are already specified by the manufacturer.

Die dortigen Schlitze bzw. Fräsungen weisen bei einer Ausbildung eine Schrägstellung bezogen auf die Längsachse des Schlüssels auf.The local slots or milling have an inclined position with respect to the longitudinal axis of the key.

Nachteilig ist jedoch der notwendige herstellungsseitige Aufwand, insbesondere bei variablen Schlitzpositionen und die trotz Winkelvariabilität nur begrenzte Anzahl von Kodiermöglichkeiten.A disadvantage, however, is the necessary production-side effort, especially in variable slot positions and despite angle variability only limited number of coding options.

Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, eine weiterentwickelte Lösung für ein Zylinderschloss-Schließsystem mit Wendeschlüssel anzugeben, wobei der Schlüssel ausgehend von bekannten Kernstiften und dementsprechenden Zuhaltungen über eine sehr umfangreiche Möglichkeit zusätzlicher Kodierungen verfügt und wobei diese Kodierungen mit einer technischen Lösung umsetzbar sind, die mit wenig herstellungsseitigem bzw. technologischem Aufwand einhergeht, gleichzeitig aber ein unberechtigtes Kopieren des Schlüssels erschwert.From the foregoing, it is therefore an object of the invention to provide a further developed solution for a cylinder lock system with reversible key, the key has, starting from known core pins and corresponding tumblers on a very extensive possibility of additional coding and these codes can be implemented with a technical solution , which goes hand in hand with little manufacturing or technological effort, but at the same time makes it difficult to copy the key without authorization.

Die Lösung der Aufgabe der Erfindung erfolgt durch ein Zylinderschloss-Schließsystem mit Wendeschlüssel gemäß der Lehre nach Patentanspruch 1, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen umfassen.The object of the invention is achieved by a cylinder lock locking system with reversible key according to the teaching of claim 1, wherein the dependent claims comprise at least expedient refinements and developments.

Die Erfindung geht demnach von einem Zylinderschloss-Schließsystem mit Wendeschlüssel dieser mit Schlüsselreide und Schlüsselbart aus. Der Schlüsselbart weist eine Vielzahl von rotationssymmetrischen Vertiefungen zur Aufnahme von stiftartigen Zuhaltungen eines entsprechenden Schließzylinders des Schließsystems auf, wobei die stiftartigen Zuhaltungen als klassische zweiteilige Reihenanordnung im Schließzylindergehäuse sowie im Zylinderkern ausgeführt sind.The invention is therefore based on a cylinder lock system with reversible key this with key and key bit. The key bit has a plurality of rotationally symmetrical depressions for receiving pin-like tumblers of a corresponding lock cylinder of the locking system, wherein the pin-like tumblers are designed as a classic two-part arrangement in the lock cylinder housing and in the cylinder core.

Erfindungsgemäß ist in mindestens einer Abstandsfläche zwischen den rotationssymmetrischen Vertiefungen der Schlüsselbart mit einer nicht rotationssymmetrischen Ausnehmung versehen. Diese nicht rotationssymmetrische zusätzliche Ausnehmung weist zwei parallele Seitenwände sowie einen Boden auf. Der Boden besitzt eine kreisbogenförmige Bodenfläche, welche von den Seitenwänden begrenzt ist, um derartig eine weitere Schlüsselkodierung zu bilden.According to the invention, the key bit is provided with a non-rotationally symmetrical recess in at least one spacer surface between the rotationally symmetrical depressions. This non-rotationally symmetrical additional recess has two parallel side walls and a bottom. The bottom has an arcuate bottom surface which is bounded by the side walls so as to form another key code.

Unter Abstandsfläche zwischen den rotationssymmetrischen Vertiefungen wird diejenige freie Fläche verstanden, die zwischen benachbarten rotationssymmetrischen Vertiefungen vorliegt.The distance surface between the rotationally symmetrical depressions is understood to be that free surface which exists between adjacent rotationally symmetrical depressions.

Bezüglich der geschaffenen nicht rotationssymmetrischen Ausnehmungen sind weitere stiftartige Zuhaltungen als zweiteilige Reihenanordnung ausgebildet, welche jeweils einen Zylinderkernstift und einen zugeordneten federbelasteten Außenstift umfassen.With respect to the created non-rotationally symmetrical recesses further pin-like tumblers are designed as a two-part series arrangement, each comprising a cylinder core pin and an associated spring-loaded outer pin.

Der Außenstift ist im Schließzylindergehäuse und der Kernstift im Zylinderkern befindlich. Die weitere Reihenanordnung ist bevorzugt der bereits vorhandenen, klassischen Reihenanordnung gegenüberliegend und/oder in diese eingebunden angeordnet bzw. vorgesehen.The outer pin is located in the lock cylinder housing and the core pin in the cylinder core. The further row arrangement is preferably arranged or provided in relation to the already existing, conventional row arrangement opposite and / or incorporated into it.

Die der weiteren zusätzlichen Schlüsselkodierung mit Blick auf die nicht rotationssymmetrischen Ausnehmungen jeweils zugeordnete Zuhaltung weist eine Zuhaltungsspitze auf, welche eine Form besitzt, die der jeweiligen nicht rotationssymmetrischen Ausnehmung im Wesentlichen komplementär ist.The further additional key coding with regard to the non-rotationally symmetrical recesses respectively assigned tumbler has a tumbler tip which has a shape that is substantially complementary to the respective non-rotationally symmetric recess.

Insofern weist die betreffende Zuhaltungsspitze eine Bogen-, insbesondere eine Kreisbogenform auf, welche zu der insbesondere kreisbogenförmigen Bodenfläche oder einem Abschnitt dieser Bodenfläche komplementär ausgebildet ist, um entsprechend in die nicht rotationssymmetrische Ausnehmung eintauchen zu können.In this respect, the respective tumbler point on a bow, in particular a circular arc shape, which is complementary to the particular arcuate bottom surface or a portion of this bottom surface, in order to dive into the non-rotationally symmetric recess accordingly.

Die jeweilige Zuhaltungsspitze stellt insofern den Kernstift für die erweiterte Kodierungsmöglichkeit dar oder bildet einen Bestandteil desselben, wobei der Kernstift unter Beibehalten seiner Verschieblichkeit um seine Längsachse gegen Rotation bzw. Verdrehen um seine eigene Achse im Zylinderkern gesichert ist.The respective tumbler tip represents the core pin for the extended coding possibility or forms part of the same, wherein the core pin is secured while maintaining its displaceability about its longitudinal axis against rotation or rotation about its own axis in the cylinder core.

Die diesbezügliche Winkelposition entspricht dann der Lage in der Ausnehmung der Seitenwände der nicht rotationssymmetrischen jeweiligen Ausnehmung.The relevant angular position then corresponds to the position in the recess of the side walls of the non-rotationally symmetric respective recess.

In einer Ausgestaltung ist die Zuhaltungsspitze als abgesetzter Teil des Kernstifts ausgebildet. Der abgesetzte Teil entspricht in seiner geometrischen Form der jeweiligen zugehörigen nicht rotationssymmetrischen Ausnehmung oder einem wesentlichen Teil dieser Ausnehmung.In one embodiment, the tumbler tip is formed as a stepped part of the core pin. The stepped part corresponds in its geometric shape of the respective associated non-rotationally symmetrical recess or a substantial part of this recess.

In einer Ausgestaltung der Erfindung verlaufen die Seitenwände der nicht rotationssymmetrischen Ausnehmungen parallel zur Längsachse des Schlüsselbarts.In one embodiment of the invention, the side walls of the non-rotationally symmetrical recesses extend parallel to the longitudinal axis of the key bit.

Alternativ oder ergänzend können die Seitenwände der nicht rotationssymmetrischen Ausnehmungen unter einem von 0° abweichenden Winkel zur Längsachse des Schlüsselbarts orientiert sein.Alternatively or additionally, the side walls of the non-rotationally symmetrical recesses may be oriented at an angle other than 0 ° to the longitudinal axis of the key bit.

Die Seitenwände der nicht rotationssymmetrischen Ausnehmungen können parallel zueinander verlaufen oder aber auch einen vorgegebenen, z.B. spitzen Winkel einschließen.The side walls of the non-rotationally symmetrical recesses may run parallel to each other or else a predetermined, e.g. Include sharp angles.

In technologisch einfacher Weise sind die nicht rotationssymmetrischen Ausnehmungen als Fräsungen und die rotationssymmetrischen Vertiefungen als Bohrungen oder Einsenkungen ausgeführt.In a technologically simple manner, the non-rotationally symmetric recesses are designed as milling and the rotationally symmetrical depressions as holes or depressions.

Die erfindungsgemäße Lösung gemäß Ausführungsbeispiel geht aus von einem klassischen Zylinderschloss-Schließsystem. In einem Zylindergehäuse 1 befindet sich ein erster Zylinderkern 2 und ein zweiter Zylinderkern 3, welche über Kupplungsmittel 4 verbindbar sind.The inventive solution according to the embodiment is based on a classic cylinder lock system. In a cylinder housing 1 is a first cylinder core 2 and a second cylinder core 3, which are connectable via coupling means 4.

Der Schlüssel 5 besitzt im Bereich seines Schlüsselbarts eine Vielzahl von rotationssymmetrischen Vertiefungen auf seiner Ober- und Unterseite, die mit stiftartigen Zuhaltungen 6; 7 im Schließzylindergehäuse sowie im Zylinderkern befindlich sind und einer klassischen zweiteiligen Reihenanordnung entsprechen.The key 5 has in the region of its key bit a plurality of rotationally symmetrical depressions on its top and bottom, with pin-like tumblers 6; 7 are located in the lock cylinder housing and in the cylinder core and correspond to a classic two-piece series arrangement.

Bei entsprechend passender Ausführungsform der rotationssymmetrischen Vertiefungen im Flachschlüssel in Verbindung mit den diesbezüglichen stiftartigen Zuhaltungen 6; 7 wird die jeweilige Sperrebene 8; 9 freigegeben und es lässt sich der Zylinderkern frei drehen.In accordance with appropriate embodiment of the rotationally symmetric depressions in the flat key in conjunction with the relevant pin-like tumblers 6; 7, the respective lock level 8; 9 released and it can rotate the cylinder core freely.

Ergänzend zu den bekannten rotationssymmetrischen Vertiefungen zur Aufnahme der zugehörigen stiftartigen Zuhaltungen sind im Bereich wenigstens einer Abstandsfläche zwischen diesen rotationssymmetrischen Vertiefungen weitere, nicht rotationssymmetrische Ausnehmungen 10 befindlich. Diese nicht rotationssymmetrischen Ausnehmungen 10 bestehen aus zwei Seitenwänden sowie einem Boden, der insbesondere eine kreisförmige Bodenfläche besitzt (siehe Detaildarstellung nach Fig. 2).In addition to the known rotationally symmetrical depressions for receiving the associated pin-like tumblers, further, non-rotationally symmetrical recesses 10 are located in the region of at least one distance surface between these rotationally symmetrical depressions. These non-rotationally symmetrical recesses 10 consist of two side walls and a bottom, which in particular has a circular bottom surface (see detailed illustration according to FIG Fig. 2 ).

Weitere stiftartige Zuhaltungen 11; 12 können als ein- oder zweiteilige Reihenanordnung ausgebildet sein. Diese weiteren stiftartigen Zuhaltungen 11; 12 jeweils einen Zylinderkernstift 13 und einen zugeordneten federbelasteten Außenstift 14 auf. Der Außenstift 14 ist im Schließzylindergehäuse 1 und der Kernstift 13 im Zylinderkern 2 befindlich.Other pin-like tumblers 11; 12 may be formed as a one- or two-part series arrangement. These other pin-like tumblers 11; 12 each have a cylinder core pin 13 and an associated spring-loaded outer pin 14. The outer pin 14 is located in the lock cylinder housing 1 and the core pin 13 in the cylinder core 2.

Die weitere Reihenanordnung kann insofern der klassischen Reihenanordnung gegenüberliegend und/oder in diese eingebunden vorgesehen sein.
Die der weiteren Schlüsselkodierung jeweils zugeordnete Zuhaltung besitzt eine Zuhaltungsspitze 131, welche eine Form aufweist, die der jeweiligen, nicht rotationssymmetrischen Ausnehmung 10 im Wesentlichen komplementär sein kann.The further series arrangement can be provided so far as opposed to the classical series arrangement and / or in this.
The tumbler in each case assigned to the further key coding has a tumbler tip 131, which has a shape that can be substantially complementary to the respective non-rotationally symmetrical recess 10.

So kann die Zuhaltungsspitze 131 eine Bogen-, insbesondere Kreisbogenform aufweisen, wie dies die Detaildarstellung nach Fig. 2 beispielhaft zeigt.Thus, the tumbler tip 131 may have a bow, in particular circular arc shape, as the detailed representation of Fig. 2 exemplifies.

Beispielhafte weitere Ausgestaltungen der Zuhaltungsspitze 131 sind in den Fig. 4 und 5 dargestellt.Exemplary further embodiments of the tumbler tip 131 are in the 4 and 5 shown.

Die jeweilige Zuhaltungsspitze 131 des Zylinderkernstifts 13 kann selbst den Kernstift bilden oder ein Bestandteil desselben sein. Der Kernstift ist unter Beibehaltung seiner Längsverschieblichkeit gegen Rotation bzw. Verdrehen um seine eigene Achse im Zylinderkern 2 gesichert, was mit Hilfe eines nockenartigen Fortsatzes 132 möglich ist, der formschlüssig in einer diesbezüglichen Ausnehmung im Zylinderkern seinen Sitz findet.The respective tumbler tip 131 of the cylinder core pin 13 may itself form the core pin or be part of the same. The core pin is secured while maintaining its longitudinal displaceability against rotation or rotation about its own axis in the cylinder core 2, which is possible with the aid of a cam-like extension 132, which finds its seat in a form-fitting recess in the cylinder core.

Gemäß den Darstellungen nach den Fig. 4 und 5 ist die Zuhaltungsspitze 131 als abgesetzter Teil des Kernstifts ausgeführt. Dieser abgesetzte Teil entspricht in seiner geometrischen Form der jeweiligen zugehörigen, nicht rotationssymmetrischen Ausnehmung 10 oder einem entsprechenden Teil dieser Ausnehmung.According to the representations after the 4 and 5 the tumbler tip 131 is designed as a stepped-off part of the core pin. This offset part corresponds in its geometric shape of the respective associated, non-rotationally symmetrical recess 10 or a corresponding part of this recess.

Die Seitenwände der nicht rotationssymmetrischen Ausnehmungen können parallel zur Längsachse des Schlüsselbarts verlaufen. Alternativ können die Seitenwände der nicht rotationssymmetrischen Ausnehmungen aber auch unter einem von 0° abweichenden Winkel zur Längsachse des Schlüsselbarts orientiert sein. Diesbezüglich ist dann auch für eine komplementäre Lage der jeweiligen zusätzlichen Zylinderkernstifte mit entsprechender Zuhaltungsspitze zu sorgen.The side walls of the non-rotationally symmetrical recesses may extend parallel to the longitudinal axis of the key bit. Alternatively, the side walls of the non-rotationally symmetrical recesses may also be oriented at an angle other than 0 ° to the longitudinal axis of the key bit. In this regard, it is then also necessary to ensure a complementary position of the respective additional cylinder core pins with a corresponding tumbler tip.

Die Darstellungen nach den Fig. 4 und 5 zeigen eine Ausbildung der Zuhaltungsspitze in Bogenform mit unterschiedlichen Radien (Radius 1 und Radius 2) und parallel verlaufenden flächigen Abschnitten 134, und zwar zum Einsatz bei diesbezüglich komplementären nicht rotationssymmetrischen Ausnehmungen mit parallel verlaufenden Seitenwänden. Wenn hingegen die Seitenwände der nicht rotationssymmetrischen Ausnehmungen nicht parallel verlaufen, sondern z.B. einen Winkel, insbesondere einen spitzen Winkel einschließen, sind die Seitenwände 134 ebenfalls komplementär winklig realisiert (nicht in den Figuren gezeigt).The representations after the 4 and 5 show an embodiment of the tumbler tip in an arc shape with different radii (radius 1 and radius 2) and parallel planar sections 134, for use in this complementary non-rotationally symmetric recesses with parallel side walls. If, on the other hand, the side walls of the non-rotationally symmetrical recesses do not run parallel, but for example enclose an angle, in particular an acute angle, the side walls 134 are also implemented as complementary angles (not shown in the figures).

Die nicht rotationssymmetrischen Ausnehmungen sind technologisch besonders einfach als Fräsungen realisierbar, wobei die rotationssymmetrischen Vertiefungen oder Ausnehmungen als Bohrungen oder Einsenkungen ausgeführt sind.The non-rotationally symmetrical recesses are technologically particularly easy to implement as milling, wherein the rotationally symmetric depressions or recesses are designed as holes or depressions.
