Description

Die Erfindung betrifft einen Schlüssel für einen Schließzylinder mit einem einen Schlüsselrücken und eine Schlüsselbrust aufweisenden Schaft und mit einer Reihe von in der Schlüsselbrust angeordneten kerbenförmigen Schließausnehmungen zur Abstützung von Stiftzuhaltungen. Weiterhin betrifft die Erfindung einen Schließzylinder für einen solchen Schlüssel mit einem in einem Gehäuse drehbaren Kern und mit einem Schließkanal zum Einführen des Schlüssels und mit einer Reihe von mit den Schließausnehmungen des Schlüssels zusammenwirkenden Stiftzuhaltungen.The invention relates to a key for a lock cylinder with a key back and a key-breast having shaft and with a number of arranged in the key-chest notch-shaped locking recesses for supporting pin tumblers. Furthermore, the invention relates to a lock cylinder for such a key with a rotatable core in a housing and with a closing channel for insertion of the key and with a series of cooperating with the locking recesses of the key pin tumblers.

Ein Schlüssel und ein Schließzylinder sind aus der DE 27 36 331 B2 bekannt. Bei diesem Schlüssel sind die Schließausnehmungen bildende Flanken um einen vorgesehenen Winkel zur Mittelachse der Schließausnehmung geneigt. Solche Schlüssel weisen Stufungen der Schließausnehmungen auf, wobei die Stufe eins beispielsweise einer geringen Tiefe der Schließausnehmung und die Stufe acht einer besonders großen Tiefe der Schließausnehmung entspricht. Beim Einführen des Schlüssels in den Schließkanal des Schließzylinders werden die Stiftzuhaltungen von den auf der Schlüsselbrust angeordneten Flanken der Schließkerben bewegt. Dabei gleitet das meist kegelförmige Ende der Stiftzuhaltung entlang der auf der Schlüsselbrust angeordneten Schließausnehmungen. Dies führt jedoch dazu, dass bei einander benachbarten Stiftzuhaltungen keine großen Stufensprünge möglich sind. Beispielsweise ist es nicht möglich, neben einer Schließausnehmung der Stufe eins mit geringer Tiefe eine Schließausnehmung der Stufe acht, also einer besonders großen Tiefe der Schließausnehmung anzuordnen. Bei einem solchen großen Stufensprung würde bei gängigen Schlüsseln die Flanke der tiefen Schließausnehmung bis in die benachbarte flache Schließausnehmung eindringen. Daher weist der bekannte Schlüssel nur eine geringe Anzahl an Kombinationsmöglichkeiten der Stufen der Schließausnehmungen und damit auch eine geringe Anzahl an Schließgeheimnissen auf.A key and a lock cylinder are out of the DE 27 36 331 B2 known. In this key, the locking recesses forming flanks are inclined by an intended angle to the central axis of the locking recess. Such keys have gradations of the closing recesses, wherein the stage one, for example, corresponds to a small depth of the closing recess and the stage eight of a particularly large depth of the closing recess. Upon insertion of the key in the lock channel of the lock cylinder, the pin tumblers are moved by the arranged on the key chest flanks of the lock notches. The usually conical end of the Stiftzuhaltung slides along the arranged on the key chest locking recesses. However, this means that with adjacent pin tumblers no large increments are possible. For example, it is not possible, in addition to a closing recess of the stage one with a shallow depth a closing recess of the stage eight, so to arrange a particularly large depth of the locking recess. With such a large increment, the flank of the deep locking recess would penetrate into the adjacent, flat locking recess with common keys. Therefore, the known key has only a small number of possible combinations of the levels of Schließausnehmungen and thus a small number of secrets.

Um dieses Problem zu vermeiden, könnte man daran denken, die Schließausnehmungen weit voneinander zu beabstanden. Dies führt jedoch bei einer begrenzten Länge des Schließzylinders zu einer geringen Anzahl an möglichen auf dem Schlüssel anzuordnenden Schließausnehmungen. Dies begrenzt ebenfalls die mögliche Anzahl an Schließgeheimnissen des Schlüssels.To avoid this problem, one might think of spacing the closing recesses far apart. However, this results in a limited length of the lock cylinder to a small number of possible to be arranged on the key locking recesses. This also limits the possible number of locking secrets of the key.

Der Erfindung liegt das Problem zugrunde, einen Schlüssel der eingangs genannten Art so weiterzubilden, dass er eine möglichst große Anzahl an Schließgeheimnissen ermöglicht. Weiterhin liegt der Erfindung das Problem zugrunde, einen Schließzylinder für einen solchen Schlüssel zu schaffen, welcher eine große Anzahl von Schließgeheimnissen ermöglicht und bei dem die Stiftzuhaltungen dem Schlüssel beim Einführen in den Schließkanal eine besonders geringe Reibung entgegensetzen.The invention is based on the problem, a key of the type mentioned in such a way that it allows the greatest possible number of privacy secrets. Furthermore, the invention is based on the problem to provide a lock cylinder for such a key, which allows a large number of locking secrets and in which the pin tumblers oppose the key when inserted into the closing channel a particularly low friction.

Das erstgenannte Problem wird erfindungsgemäß dadurch gelöst, dass die Schließausnehmungen bildenden Flanken oberhalb einer vorgesehenen Tiefe der jeweiligen Schließausnehmung in Abschnitte unterteilt sind und dass eine Übergangsfläche von einem Abschnitt zum nächst tiefer in dem Schaft angeordneten Abschnitt eine Erweiterung der Schließausnehmung bildet.The first problem is inventively achieved in that the closing recesses forming flanks are subdivided into sections above an intended depth of the respective locking recess and that a transition surface from one section to the next lower in the shaft arranged portion forms an extension of the closing recess.

Durch diese Gestaltung weisen die Schließausnehmungen oberhalb einer vorgesehenen Tiefe ein Profil nach Art eines Tannenbaums auf. Dies führt dazu, dass die Flanken einer besonders tiefen Schließausnehmung zur Schlüsselbrust von Abschnitt zu Abschnitt die Breite der Schließausnehmung verringern. Im Vergleich zu dem bekannten Schlüssel ist bei dem erfindungsgemäßen Schlüssel die Breite tiefer Schließausnehmungen geringer, wenn die Winkel der Flanken der einzelnen Abschnitte der Schließausnehmungen des erfindungsgemäßen Schlüssels und der Winkel der Flanken der Schließausnehmungen des bekannten Schlüssels gleich sind. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass der Schlüssel durch die verschiedenen Abschnitte nur sehr schwer zu kopieren ist.As a result of this design, the closing recesses have a profile in the manner of a Christmas tree above a planned depth. As a result, the flanks of a particularly deep closing recess for the key-breast are reduced from section to section in the width of the closing recess. Compared to the known key, the width of deep locking recesses is smaller in the key according to the invention, when the angle of the flanks of the individual sections of the locking recesses of the key according to the invention and the angle of the flanks of the locking recesses of the known key are the same. Another advantage of this design is that the key through the various sections is very difficult to copy.

Ränder von Stiftzuhaltungen gleiten gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders reibungsarm entlang der Flanken der Schließausnehmungen, wenn zwischen der Übergangsfläche und dem angrenzenden Abschnitt eine zur Abstützung der Stiftzuhaltung des Schließzylinders vorgesehene Kante angeordnet ist.According to another advantageous development of the invention, edges of pin tumblers slide in a particularly low-friction manner along the flanks of the locking recesses when an edge provided for supporting the pin tumbler of the lock cylinder is arranged between the transition surface and the adjacent section.

Der erfindungsgemäße Schlüssel gestaltet sich konstruktiv besonders einfach, wenn die Abschnitte die Flanken der Schließausnehmung treppenförmig unterteilen.The key according to the invention is structurally particularly simple if the sections divide the flanks of the closing recess in a staircase.

Hohe Absätze bei kurzen Übergangsflächen lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erzeugen, wenn die Übergangsfläche in einem scharfen Winkel zu den angrenzenden Abschnitten angeordnet ist.High heels with short transitional surfaces can be easily produced according to another advantageous development of the invention, if the transition surface is arranged at a sharp angle to the adjacent sections.

Die Schließausnehmungen des erfindungsgemäßen Schlüssels weisen eine gleichmäßige Reibung gegenüber den Stiftzuhaltungen des Schließzylinders auf, wenn die Neigungswinkel einander benachbarter Abschnitte gleich sind.The locking recesses of the key according to the invention have a uniform friction against the pin tumblers of the lock cylinder, when the inclination angle of adjacent sections are equal.

Das zweitgenannte Problem, nämlich die Schaffung eines Schließzylinders für einen solchen Schlüssel, welcher eine große Anzahl von Schließgeheimnissen ermöglicht und bei dem die Stiftzuhaltungen dem Schlüssel beim Einführen in den Schließkanal eine besonders geringe Reibung entgegensetzen, wird erfindungsgemäß dadurch gelöst, dass die Stiftzuhaltungen in ihrem zentrischen, in den Schließkanal hineinragenden Ende einen nippelförmigen Vorsprung aufweisen.The second-mentioned problem, namely the creation of a lock cylinder for such a key, which allows a large number of locking secrets and in which the pin tumblers the key when inserted into the closing channel particularly low friction, is inventively achieved in that the pin tumblers in their centric , End projecting into the closing channel have a nippelförmigen projection.

Durch diese Gestaltung gleitet die Stiftzuhaltung mit ihrem nippelförmigen Vorsprung und einer Kante am Umfang beim Einführen des Schlüssels in den Schließzylinder entlang der Schlüsselbrust. Die Reibung wird dabei von den Kanten der Abschnitte an den Übergangsflächen zusätzlich besonders gering gehalten. Dies ermöglicht es, den Schließzylinder mit besonders hohen Stufensprüngen einander benachbarter Stiftzuhaltungen zu gestalten, ohne dass hierbei der von den Stiftzuhaltungen erzeugte Widerstand beim Einführen des Schlüssels in den Schließzylinder ansteigt. Die großen möglichen Stufensprünge ermöglichen die Gestaltung des Schließzylinders mit einer besonders großen Anzahl von Schließgeheimnissen.By virtue of this configuration, the pin tumbler slides with its nipple-shaped projection and an edge on the circumference when the key is inserted into the lock cylinder along the spanner's breast. The friction is additionally kept particularly low by the edges of the sections at the transition surfaces. This makes it possible to design the lock cylinder with particularly high incremental steps of adjacent pin tumblers, without this increasing the resistance generated by the pin tumblers when inserting the key into the lock cylinder. The large possible increments allow the design of the lock cylinder with a particularly large number of locking secrets.

Figur 1 zeigt einen Schlüssel 1 mit einem zum Schließen mit dem Schlüssel 1 vorgesehenen Schließzylinder 2 im Teilschnitt. Der Schlüssel 1 hat einen Schaft 3 mit einem Schlüsselrücken 4 und mit einer Reihe an einer Schlüsselbrust 5 angeordneten Schließausnehmungen 6. Der Schließzylinder 2 hat einen in einem Gehäuse 7 drehbaren Kern 8 und einen in dem Kern 8 angeordneten Schließkanal 9. Weiterhin hat der Schließzylinder 2 eine Reihe von in dem Gehäuse 7 geführten und in den Schließkanal 9 des Kerns 8 hineinragende Stiftzuhaltungen 10. Die Reihe der Stiftzuhaltungen 10 wirkt bei in den Schließzylinder 2 eingeführtem Schlüssel 1 mit der Reihe der Schließausnehmungen 6 des Schlüssels 1 zusammen.Figure 1 shows a key 1 with a provided for closing with the key 1 lock cylinder 2 in partial section. The key 1 has a shaft 3 with a key back 4 and with a number on a key chest 5 arranged locking recesses 6. The lock cylinder 2 has a rotatable housing 7 in a core 8 and arranged in the core 8 closing channel 9. Furthermore, the lock cylinder has the second a series of guided in the housing 7 and projecting into the lock channel 9 of the core 8 pin tumblers 10. The series of Stiftzuhaltungen 10 acts in introduced into the lock cylinder 2 key 1 with the series of locking recesses 6 of the key 1 together.

Figur 2 zeigt stark vergrößert zwei der Schließausnehmungen 6 des Schlüssels 1 aus Figur 1. Zur Verdeutlichung sind vorgesehene Stufungen der Schließausnehmungen 6 in der Zeichnung von null bis acht dargestellt. Die Stufe null entspricht einer Schließausnehmung 6 mit besonders geringer Tiefe, während Stufe acht eine besonders große Tiefe der Schließausnehmung 6 darstellt. Eine der dargestellten Schließausnehmungen 6 hat die Stufe acht, während die benachbarte Schließausnehmung 6 die Stufe null hat. Zur Verdeutlichung sind Mittellinien der benachbarten Schließausnehmungen 6 in der Zeichnung strichpunktiert dargestellt. Die Schließausnehmung 6 der Stufe acht weist Flanken 11 mit einem Flankenwinkel α zur Mittellinie auf. Die Flanken 11 sind in mehrere Abschnitte 12 unterteilt, welche über Übergangsflächen 13 miteinander verbunden sind. Die Übergangsflächen 13 bilden von einem Abschnitt 12 zum nächst tiefer in dem Schaft 3 angeordneten Abschnitt 12 eine Erweiterung der tiefen Schließausnehmung 6. Dies vermeidet, dass die Schließausnehmung 6 der Stufe acht in die benachbarte Schließausnehmung 6 der Stufe null eindringt. Damit lassen sich eng benachbarte Schließausnehmungen 6 mit dem dargestellten, größtmöglichen Stufensprung von Stufe null zu Stufe acht auf der Schlüsselbrust 5 anordnen.Figure 2 shows greatly enlarged two of the locking recesses 6 of the key 1 of Figure 1. For clarity, provided gradations of the locking recesses 6 are shown in the drawing from zero to eight. The level zero corresponds to a closing recess 6 with a particularly small depth, while stage eight represents a particularly large depth of the closing recess 6. One of the locking recesses 6 shown has the level eight, while the adjacent closing recess 6 has the stage zero. For clarity centerlines of the adjacent locking recesses 6 are shown in phantom in the drawing. The closing recess 6 of the stage eight has flanks 11 with a flank angle α to the center line. The flanks 11 are divided into a plurality of sections 12 which are interconnected via transitional surfaces 13. The transition surfaces 13 form from a portion 12 to the next deeper in the shaft 3 arranged portion 12 an extension of the deep closing recess 6. This avoids that the closing recess 6 of the stage eight penetrates into the adjacent closing recess 6 of the stage zero. This can be closely adjacent locking recesses 6 with the illustrated, the largest possible increment from level zero to level eight on the key chest 5 order.

Figur 3 zeigt stark vergrößert das in den Schließkanal 9 hineinragende Ende einer der Stiftzuhaltungen 10 des Schließzylinders 2 aus Figur 1. Hierbei ist zu erkennen, dass die Stiftzuhaltung 10 in ihrem zentrischen, in den Schließkanal 9 hineinragenden Bereich einen nippelförmigen Vorsprung 14 aufweist.FIG. 3 greatly enlarges the end of one of the pin tumblers 10 of the lock cylinder 2 from FIG. 1 projecting into the closing channel 9. It can be seen here that the pin tumbler 10 has a nipple-shaped projection 14 in its central region projecting into the closing channel 9.
