Zuhaltungen vorgesehen sind, die die mechanische Kodierung des Schlüssels abtasten und bei passender Kodierung eine Drehung des Zylinderkernes zulassen und damit einen Schließvorgang ermöglichen, Tumblers are provided which sense the mechanical coding of the key and, with appropriate coding, allow rotation of the cylinder core and thus enable a closing operation,
dadurch, dass der Schlüsselkanal eine mit einer der seitlichen Profilierungen des Schlüssels korrespondierende Profilierung aufweist, dass die seitliche Profilierung des Schlüsselkanals eine Freimachung aufweist, in die eine im Schlüssel federnd gelagerte Kugel hineinragt, in that the key channel has a profile corresponding to one of the lateral profiles of the key, that the lateral profiling of the keyway has a franking into which a spring-mounted ball protrudes in the key,
dass der letzte Kernstift im Zylinderkern eine Nut oder Ausnehmung aufweist, mit der ein im Zylinderkern drehbar gelagerter Fingerstift in Eingriff bringbar ist, um den Kernstift in seiner Sperrstellung zu halten, wobei der Fingerstift beim Einführen des Schlüssels durch die Kugel dreh- und außer Eingriff mit der Nut des Kernstiftes bringbar ist. in that the last core pin in the cylinder core has a groove or recess with which a finger pin rotatably mounted in the cylinder core can be engaged to hold the core pin in its locking position, wherein the finger pin rotates and disengages as the key is inserted through the ball the groove of the core pin can be brought.
Vorzugsweise Weiterbildungen ergeben sich aus den Unteransprüchen und werden nachfolgend noch erläutert. Preferably further developments will become apparent from the dependent claims and will be explained below.
Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen erläutert werden. Dabei zeigt: Fig. 1 schematisch einen teilweise in den Schließzylinder eingeführten Schlüssel, Fig. 2a einen Schnitt durch den Schließzylinder gemäß der Linie B-B in Figur 1 und Fig. 2b einen Schnitt gemäß A-A in Figur 1. The invention will be explained below with reference to the drawings. 1 schematically shows a key partially inserted into the lock cylinder, FIG. 2a shows a section through the lock cylinder along the line B-B in FIG. 1 and FIG. 2b shows a section according to A-A in FIG.
Dargestellt ist hier der Sperrzustand, der beim weiteren Einführen des Schlüssels Shown here is the lock state, the further insertion of the key
aufgehoben werden würde. would be lifted.
Im Schlüssel 2 befindet sich eine gefederte Kugel 6, 7, die im ersten parazentrischen Profilmerkmal 8 sitzt und - bei dem hier gezeigten Ausführungsbeispiel - sich nach oben, in Richtung Schlüsselrücken bewegen kann. In the key 2 is a spring-loaded ball 6, 7, which sits in the first paracentric profile feature 8 and - in the embodiment shown here - can move upwards, towards the back of the key.
In Abwandlung dieser Ausführung könnte diese Kugel auch in der Schlüsselseite angeordnet sein, vorausgesetzt, dass das dem Schlüsselprofil zugeordnete parazentrische Profil im Zylinderkern (Schlüsselkanal) die Kugel beim Einführen des Schlüssels in den In a modification of this embodiment, this ball could also be arranged in the key side, provided that the key profile associated paracentric profile in the cylinder core (key channel) the ball when inserting the key in the
Schlüsselschaft hinein drücken kann. Key shaft can press into it.
Im Zylinderkern 1 hat der letzte Kernstift 3 eine Nut 9, in die ein drehbar - parallel zum Schlüsselkanal - gelagerter Fingerstift 4 mit dem Finger 12 eingreift. In the cylinder core 1, the last core pin 3 has a groove 9, in which a rotatable - parallel to the key channel - mounted finger pin 4 engages with the finger 12.
Dieser Stift hat einen zweiten Finger 10, der in Höhe des ersten parazentrischen This pen has a second finger 10, the height of the first paracentric
Profilmerkmals sitzt und von diesem "verdeckt" wird. Das Profilmerkmal des Kerns ist an dieser Stelle ausgenommen. Profile feature sits and is "hidden" by this. The profile feature of the core is excluded at this point.
Wird der Schlüssel nun in den Schlüsselkanal eingeführt, dann drückt das parazentrische Profil des Zylinderkernes die Kugel in den Schlüssel 1 , bis die Freimachung erreicht ist und die Kugel durch die Feder 7 wieder nach unten gedrückt wird. Beim weiteren Einführen des Schlüssels nimmt die Kugel den zweiten Finger 10 des Fingerstiftes 4 mit und verdreht ihn etwas, bis der Kernstift 3 freigegeben wird und von der Schlüsselspitze herunter gedrückt werden kann, wobei der Kernstift soweit verschoben wird, dass er unter Mitwirkung des üblichen Gehäusestiftes die Trennebene Zylinderkern/Zylindergehäuse und damit seine bisherige Sperrstellung freigibt.. If the key is now inserted into the keyway, then the paracentric profile of the cylinder core pushes the ball into the key 1 until the clearance is reached and the ball is pushed down again by the spring 7. Upon further insertion of the key, the ball takes the second finger 10 of the finger pin 4 with and twisted it slightly until the core pin 3 is released and can be pressed down by the key tip, wherein the core pin is moved so far that he in cooperation with the usual housing pin the parting plane cylinder core / cylinder housing and thus releases its previous locking position ..
Der Fingerstift 4 wird beim Herausziehen des Schlüssels durch die Feder 5 wieder in die Ursprungslage zurück gedreht.  The finger pin 4 is rotated when pulling out the key by the spring 5 back to the original position.
Ist keine Kugel im Schlüssel 2, oder nicht an der richtigen Position, dann kann der Schlüssel 2 nicht komplett in den Schlüsselkanal des Zylinderkernes 1 eingeführt werden, da der letzte Kernstift 3 durch den Fingerstift 4 bzw. dessen Finger 12 blockiert wird und somit nicht herunter gedrückt werden kann. If no ball in the key 2, or not in the correct position, then the key 2 can not be completely inserted into the key channel of the cylinder core 1, since the last core pin 3 is blocked by the finger pin 4 and its fingers 12 and thus not down can be pressed.
Der Vorteil der erfindungsgemäßen Lösung besteht darin, dass sie einerseits einen technischen Schlüsselkopierschutz darstellt und zum Anderen in bestehende Systeme integrierbar ist. The advantage of the solution according to the invention is that on the one hand it represents a technical key copy protection and on the other hand it can be integrated into existing systems.
