Die Erfindung betrifft einen Schlüssel, insbesondere Wendeschlüssel für ein Zylinderschloss-Schließsystem mit Schlüsselreide und Schlüsselbart, wobei der Schlüsselbart eine Vielzahl von rotationssymmetrischen Vertiefungen zur Aufnahme von stiftartigen Zuha ltungen eines Schließzylinders aufweist, wobei die stiftartigen Zuhaltungen als klassische zweiteilige Reihenanordnung im Schließzylindergehäuse sowie im Zyli nderkern ausgeführt sind, gemäß The invention relates to a key, in particular reversible key for a cylinder lock system with key and key bit, wherein the key bit has a plurality of rotationally symmetrical depressions for receiving pin-like Zuha obligations of a lock cylinder, wherein the pin-like tumblers as a classic two-part arrangement in the lock cylinder housing and in the cyli kernel are executed according to
Oberbegriff des Anspruchs 1. Preamble of claim 1.
Aus der US 5, 682, 779 ist ein System aus Schlüssel und Zylinderschloss vorbekannt, welches weitere Kodiermöglichkeiten und eine höhere Sicherheit schaffen soll . From US 5, 682, 779 a system of key and cylinder lock is already 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 ei ngreifen . This is achieved in that slots are provided in the key, which correspond with pins in the cylinder, which have a prismatic shape and engage with their top in the respective slots ei.
Die Schlitze i m Schlüssel können einerseits auf der Längsachse liegen bzw . parallel zu dieser angeordnet sein, aber auch ganz unterschiedliche The slots in the key can lie on the longitudinal axis on the one hand. be arranged parallel to this, but also very different
Winkelorientierungen besitzen. Konkret wird diesbezüg lich auf Winkel im Bereich zwischen 0° bis 360° verwiesen. Bei einer bevorzugten Ausgestaltung der Lösung nach US 5,682,779 ist die Wi nkelposition einstel lbar gestaltet, um auch kundenseitig eine individuelle Kodierung vornehmen zu können. Bei einer weiteren Ausführungsvariante sind die Winkel und die Position der einzelnen Sch litze bereits herstellerseitig fest vorgegeben . Have angular orientations. Specifically, reference is made in this respect to angles in the range between 0 ° to 360 °. In a preferred embodiment of the solution according to US Pat. No. 5,682,779, the Wi nkelposition is designed einstel lbar in order to make an individual coding by the customer can. In a further embodiment, the angle and the position of the individual Sch strand are already specified by the manufacturer.
Die dortigen Schlitze bzw. Fräsungen weisen bei einer Ausbildung eine The local slots or milling have a training a
Schrägstellung bezogen auf die Längsachse des Schlüssels auf. Nachteilig ist jedoch der notwendige herstel lungsseitige Aufwand, insbesondere bei variablen Schlitzpositionen und die trotz Winkelvariabilität nur begrenzte Anzahl von Kodiermöglichkeiten . Inclined relative to the longitudinal axis of the key. A disadvantage, however, is the necessary manufacturing side effort, especially for variable slot positions and despite angle variability only limited number of coding options.
Aus dem Vorgenannten ist es daher Aufgabe der Erfi ndung, eine weiterentwickelte Lösung für einen Schlüssel, insbesondere Wendeschlüssel für ein Zyiinderschloss-Schließsystem 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 above, it is therefore an object of the invention to provide a further developed solution for a key, in particular reversible key for a Zyiinderschloss locking system, the key starting from known core pins and corresponding tumblers has a very extensive possibility of additional encodings and these codings with a technical solution can be implemented, which goes hand in hand with little production-side or technological effort, but at the same time makes it difficult to unauthorized copying the key.
