Description

Die Erfindung betrifft einen Schlüssel für einen Schließzylinder mit einem Schaft und mit einem in dem Schaft angeordneten Steuerglied zur Ansteuerung eines in dem Schließzylinder angeordneten Sperrstiftes. Weiterhin betrifft die Erfindung einen Schließzylinder für einen Schlüssel mit einem in einem Gehäuse drehbaren Kern, mit einem in dem Kern angeordneten Schließkanal zur Aufnahme des Schlüssels und mit einem in dem Kern verschieblich geführten und einer Tasche im Gehäuse gegenüberstehenden und in den Schließkanal hinein ragenden Sperrstift.The invention relates to a key for a lock cylinder with a shaft and with a arranged in the shaft control member for controlling a arranged in the lock cylinder locking pin. Furthermore, the invention relates to a lock cylinder for a key with a rotatable core in a housing, with a arranged in the core closing channel for receiving the key and with a displaceably guided in the core and a pocket in the housing opposite and projecting into the locking channel locking pin.

Eine Schließeinrichtung mit einem solchen Schließzylinder und einem solchen Schlüssel ist beispielsweise aus der DE 35 18 743 A1 bekannt. Bei dieser Schließeinrichtung ist das Steuerglied in dem Schaft des Schlüssels quer zur Längsachse des Schaftes verschieblich geführt. Der in dem Schließzylinder angeordnete Sperrstift tastet ein Ende des Steuergliedes ab. Das andere Ende des Steuergliedes wird von einem in dem Kern des Schließzylinders angeordneten Einsatzstück abgestützt. Daher lässt sich der Schließzylinder mittels des Schlüssels nur entriegeln, wenn durch die Position und die Länge des Steuergliedes der Sperrstift in einer vorgesehenen Position gegenüber der Tasche des Gehäuses gehalten wird. Der Sperrstift steht einer Seitenfläche des Schaftes gegenüber und bildet damit ein weiteres Schließgeheimnis des Schlüssels. Zudem hat der Schlüssel eine Reihe von Schließkerben als weiteres Schließgeheimnis zur Ansteuerung von Stiftzuhaltungen des Schließzylinders.A locking device with such a lock cylinder and such a key is for example from the DE 35 18 743 A1 known. In this locking device, the control member is guided displaceably in the shank of the key transversely to the longitudinal axis of the shaft. The locking pin arranged in the lock cylinder scans an end of the control member. The other end of the control member is supported by a arranged in the core of the lock cylinder insert. Therefore, the lock cylinder can be unlocked by the key only when held by the position and the length of the control member of the locking pin in a predetermined position relative to the pocket of the housing. The locking pin is opposite to a side surface of the shaft and thus forms another key to secrecy of the key. In addition, the key has a number of closing notches as Another secret for the control of pin tumblers of the lock cylinder.

Nachteilig bei der bekannten Schließeinrichtung ist, dass der Schlüssel und der Schließzylinder sehr aufwändig zu fertigende Bauteile sind. Hierdurch weisen der Schlüssel und der Schließzylinder sehr hohe Fertigungskosten auf. Weiterhin lassen sich die Position und die Länge des Steuergliedes durch Abmessen des Schlüssels einfach ermitteln. Der Schlüssel ist daher besonders einfach kopierbar.A disadvantage of the known locking device is that the key and the lock cylinder are very complex to be manufactured components. As a result, the key and the lock cylinder on very high production costs. Furthermore, the position and the length of the control member can be easily determined by measuring the key. The key is therefore very easy to copy.

Der Erfindung liegt das Problem zugrunde, einen Schlüssel der eingangs genannten Art so zu gestalten, dass er besonders kostengünstig zu fertigen ist.The invention is based on the problem of designing a key of the type mentioned so that it is particularly inexpensive to manufacture.

Das erstgenannte Problem wird erfindungsgemäß dadurch gelöst, dass das Steuerglied zusammen mit einer Seitenfläche des Schaftes eine vom freien Ende des Schaftes aus zugängliche Hinterschneidung zur Bewegung des in dem Schließzylinder angeordneten Sperrstiftes begrenzt und sich die Hinterschneidung von dem freien Ende des Schaftes weg verjüngt.The first problem is inventively solved in that the control member together with a side surface of the shaft from the free end of the shaft accessible from undercut limited to the movement of the lock cylinder arranged in the locking pin and the undercut tapers away from the free end of the shaft.

Durch diese Gestaltung lässt sich das in den Schließkanal eingeführte Ende des Sperrstiftes beim Einführen des erfindungsgemäßen Schlüssels in den Schließkanal mittels der Hinterschneidung greifen und in die vorgesehene Position bewegen. Eine verschiebliche Führung des Steuergliedes ist dank der Erfindung nicht erforderlich. Daher ist der erfindungsgemäße Schlüssel zudem unempfindlich gegenüber Verschmutzung und lässt sich besonders kostengünstig fertigen. Die Verjüngung der Hinterschneidung ermöglicht es, die Sperrstift von dem Gehäuse des Schließzylinders wegzuziehen. Weiterhin wird bei in den Schließzylinder eingeschobenem Schlüssel der Sperrstift im Schließzylinder zuverlässig in der Hinterschneidung gehalten. Die Position des Sperrstiftes wird zudem von der Kontur des Steuergliedes und der Art der Verjüngung der Hinterschneidung festgelegt. Der erfindungsgemäße Schlüssel ist daher nur schwer kopierbar.By this design, the inserted into the closing channel end of the locking pin when inserting the key according to the invention in the closing channel by means of the undercut can be used and move in the intended position. A sliding guide of the control member is not required thanks to the invention. Therefore, the key according to the invention is also insensitive to contamination and can be manufactured particularly cost-effectively. The taper of the undercut makes it possible to pull the locking pin away from the housing of the lock cylinder. Furthermore, when inserted into the lock cylinder key the locking pin in the lock cylinder reliably held in the undercut. The position of the locking pin is also determined by the contour of the control member and the type of taper of the undercut. The key according to the invention is therefore difficult to copy.

Der erfindungsgemäße Schlüssel lässt sich besonders kostengünstig fertigen, wenn das Steuerglied fest mit dem Schaft verbunden ist. Durch diese Gestaltung benötigt das Steuerglied keine aufwändige Führung oder Lagerung in dem Schaft. Das Steuerglied lässt sich daher besonders einfach und kostengünstig an dem Schaft montieren.The key according to the invention can be manufactured particularly cost-effectively, if the control member is firmly connected to the shaft. By virtue of this design, the control member does not require expensive guidance or storage in the shaft. The control element can therefore be mounted on the shaft in a particularly simple and cost-effective manner.

Der bauliche Aufwand zur Erzeugung der Hinterschneidung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn das Steuerglied eine Rampe zur Verjüngung der Hinterschneidung aufweist.The structural complexity for generating the undercut can be kept particularly low according to another advantageous embodiment of the invention, when the control member has a ramp for tapering the undercut.

Mechanische Belastungen des Steuergliedes während der Aufbewahrung des erfindungsgemäßen Schlüssels in einer Tasche lassen sich einfach vermeiden, wenn das Steuerglied in einer parallel zur Längsachse des Schaftes angeordneten Nut befestigt ist. Hierdurch wird zudem eine Beschädigung der zur Aufbewahrung des Schlüssels vorgesehenen Tasche oder eine Verletzungsgefahr durch das Steuerglied vermieden. Vorzugsweise befindet sich das freie Ende des Steuergliedes auf einer Höhe mit der Seitenfläche des Schaftes.Mechanical loads on the control member during storage of the key according to the invention in a pocket can be easily avoided if the control member is mounted in a groove arranged parallel to the longitudinal axis of the shaft. In this way, damage to the pocket provided for storage of the key or a risk of injury by the control member is also avoided. Preferably, the free end of the control member is at a level with the side surface of the shank.

Der Sperrstift in dem Schließzylinder lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung mit einer großen Formenvielfalt ausstatten, wenn die Nut breiter ist als das Steuerglied. Dies trägt zur Erhöhung der Anzahl der möglichen Schließgeheimnisse des erfindungsgemäßen Schlüssels bei.The locking pin in the lock cylinder can be equipped according to another advantageous embodiment of the invention with a large variety of forms when the groove is wider than the control member. This contributes to increasing the number of possible secrets of the key according to the invention.

Der Sperrstift in dem Schließzylinder wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung nach jedem Abziehen des erfindungsgemäßen Schlüssels zuverlässig in die den Schließzylinder blockierende Stellung gedrückt, wenn ein Boden der Nut zwischen dem Steuerglied und dem freien Ende des Schaftes eine wellenförmige Erhebung aufweist. Durch diese Gestaltung benötigt der Sperrstift kein Federelement zu seiner Vorspannung in die Grundstellung.The locking pin in the lock cylinder is reliably pressed according to another advantageous embodiment of the invention after each removal of the key according to the invention in the locking cylinder blocking position when a bottom of the groove between the control member and the free end of the shaft has a wave-shaped elevation. By this design, the locking pin does not require a spring element to its bias in the normal position.

Eine großflächige und dauerhafte Befestigung des Steuergliedes an dem Schaft lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erreichen, wenn das Steuerglied einstückig mit einer Leiste gefertigt ist und wenn die Leiste parallel zur Längsachse des Schaftes angeordnet ist.A large-area and permanent attachment of the control member to the shaft can be achieved easily according to another advantageous embodiment of the invention, when the control member is made in one piece with a bar and when the bar is arranged parallel to the longitudinal axis of the shaft.

Der erfindungsgemäße Schlüssel weist einen besonders hohen Kopierschutz auf, wenn die Leiste mit einem Vorsprung eine zweite, quer zur Längsachse des Schaftes hin offene Hinterschneidung begrenzt. Da die Hinterschneidung und ein in der Hinterschneidung angeordnetes Profil der Leiste und/oder der Nut dem Schlüssel nicht ohne weiteres ersichtlich ist, wird das Kopieren des erfindungsgemäßen Schlüssels wesentlich erschwert. Sofern die Hinterschneidung die Nut um zumindest 50% überdeckt, kann diese zudem nicht mehr mit einem Fräswerkzeug gefertigt werden, was zu einer weiteren Erschwerung des Kopierens des erfindungsgemäßen Schlüssels beiträgt.The key according to the invention has a particularly high copy protection when the bar with a projection defines a second, transverse to the longitudinal axis of the shaft open undercut. Since the undercut and arranged in the undercut profile of the bar and / or the groove of the key is not readily apparent, the copying of the key according to the invention is much more difficult. If the undercut covers the groove by at least 50%, it can no longer be manufactured with a milling tool, which contributes to further complicating the copying of the key according to the invention.

Die Leiste ermöglicht die Erzeugung eines Anschlags für den erfindungsgemäßen Schlüssel in dem Schließzylinder, wenn das zum freien Ende des Schaftes weisende Ende der Leiste von dem freien Ende des Schaftes beabstandet ist.The strip allows the generation of a stop for the key according to the invention in the lock cylinder when the end of the strip facing the free end of the shaft is spaced from the free end of the shaft.

Dies trägt zur weiteren Erhöhung der Anzahl der Schließgeheimnisse des erfindungsgemäßen Schlüssels bei.This contributes to the further increase in the number of locking secrets of the key according to the invention.

Eine besonders feste und dauerhafte Fügung des Steuergliedes mit dem Schaft lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erreichen, wenn das Steuerglied mit dem Schaft verpresst oder verlötet ist.A particularly firm and permanent joining of the control member with the shaft can be achieved easily according to another advantageous embodiment of the invention, when the control member is pressed or soldered to the shaft.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt in

Figur 1 zeigt einen Schlüssel 1 und einen Schließzylinder 2. Der Schlüssel 1 hat eine Reide 3 und einen Schaft 4 mit einer an einer Schlüsselbrust 5 angeordneten Reihe von Schließkerben 6. Der Schließzylinder 2 hat einen in einem Gehäuse 7 drehbaren Kern 8 und eine Reihe von Stiftzuhaltungen 9, welche in der dargestellten Stellung die Bewegung des Kerns 8 blockieren. Die Stiftzuhaltungen 9 ragen in einen Schließkanal 10 für den Schlüssel 1 hinein. Bei in den Schließkanal 10 eingeführtem Schlüssel 1 werden die Stiftzuhaltungen 9 von den Schließkerben 6 in eine die Bewegung des Kerns 8 freigebende Stellung bewegt. In einer Seitenfläche 11 des Schaftes 4 hat der Schlüssel 1 eine Nut 12 mit einer darin befestigten Leiste 13. Die Nut 12 ist breiter als die Leiste 13.Figure 1 shows a key 1 and a lock cylinder 2. The key 1 has a Reide 3 and a shaft 4 with a arranged on a key-chest 5 series of closing notches 6. The lock cylinder 2 has a rotatable in a housing 7 core 8 and a number of Pin tumblers 9, which block the movement of the core 8 in the position shown. The pin tumblers 9 protrude into a closing channel 10 for the key 1 inside. When inserted into the lock channel 10 key 1, the pin tumblers 9 are moved by the locking notches 6 in a movement of the core 8 releasing position. In a side surface 11 of the shank 4, the key 1 has a groove 12 with a strip 13 fastened therein. The groove 12 is wider than the strip 13.

Figur 2 zeigt in einer Schnittdarstellung entlang der Linie II - II durch den Schlüssel 1 und den Schließzylinder 2 aus Figur 1, dass an dem freien Ende der Leiste 13 ein Steuerglied 14 angeordnet ist, welches mit dem Grund der Nut 12 eine Hinterschneidung 15 begrenzt. Die Hinterschneidung 15 verjüngt sich von dem freien Ende des Schaftes 4 aus gesehen. In den Schließkanal 10 des Schließzylinders 2 ragt ein Sperrstift 16 geringfügig hinein. Der Sperrstift 16 ist im Kern 8 zum Schließkanal 10 quer verschiebbar geführt. Das in den Schließkanal 10 hinein ragende Ende des Sperrstiftes 16 ist entsprechend dem Steuerglied 14 geformt. In der dargestellten Stellung dringt das dem Schließkanal 10 abgewandte Ende des Sperrstiftes 16 in eine Tasche 17 des Gehäuses 7 ein und blockiert damit die Bewegung des Kerns 8 gegenüber dem Gehäuse 7. Die Bewegung des Kerns 8 wird erst freigegeben, wenn der Sperrstift 16 aus der Tasche 17 des Gehäuses 7 heraus gezogen wird. Die Leiste 13 ist von dem freien Ende des Schaftes 4 beabstandet. Die Nut 12 hat zwischen dem Steuerglied 14 und dem freien Ende des Schaftes 4 eine wellenförmige Erhebung 18.Figure 2 shows in a sectional view along the line II - II by the key 1 and the lock cylinder 2 of Figure 1, that at the free end of the bar 13, a control member 14 is arranged, which defines an undercut 15 with the bottom of the groove 12. The undercut 15 tapers as seen from the free end of the shaft 4. In the closing channel 10 of the lock cylinder 2, a locking pin 16 protrudes slightly into it. The locking pin 16 is guided transversely displaceable in the core 8 to the closing channel 10. The projecting into the closing channel 10 in the end of the locking pin 16 is shaped according to the control member 14. In the illustrated position, the closing channel 10 facing away from the end of the locking pin 16 penetrates into a pocket 17 of the housing 7 and thus blocks the movement of the core 8 relative to the housing 7. The movement of the core 8 is released only when the locking pin 16 from the Pocket 17 of the housing 7 is pulled out. The strip 13 is spaced from the free end of the shaft 4. The groove 12 has a wave-shaped elevation 18 between the control member 14 and the free end of the shaft 4.

Beim Einführen des Schlüssels 1 in den Schließkanal 10 gelangt das Steuerglied 14 gegen den Sperrstift 16. Da sich die Hinterschneidung 15 durch die Form des Steuergliedes 14 verjüngt, wird der Sperrstift 16 in den Schließkanal 10 hinein und aus der Tasche 17 des Gehäuses 7 heraus gezogen. Damit wird die Bewegung des Kerns 8 gegenüber dem Gehäuse 7 freigegeben. Diese Stellung des Steuergliedes 14 und des Sperrstiftes 16 ist stark vergrößert in Figur 3 dargestellt. Hierbei ist zu erkennen, dass eine radiale Verbreiterung 19 des Sperrstiftes 16, welche in der Hinterschneidung 15 gehalten ist, von einer Einschnürung 20 des Sperrstiftes 16 begrenzt ist. Der Sperrstift 16 und das Steuerglied 14 bilden zudem einen Anschlag beim Einführen des Schlüssels 1 in den Schließkanal 10. Die das Steuerglied 14 aufweisende Leiste 13 hat einen Bolzen 21, mit dem sie in einer Ausnehmung 22 des Schlüssels 1 verpresst ist. Beim Herausziehen des Schlüssels 1 aus dem Schließkanal 10 gelangt die wellenförmige Erhebung 18 gegen den Sperrstift 16 und drückt diesen in die Tasche 17 des Gehäuses 7. Damit ist die Bewegung des Kerns 8 wieder blockiert. In einer nicht dargestellten Ausführungsform kann der Sperrstift 16 auch mit einem Federelement in die Tasche 17 des Gehäuses 2 vorgespannt sein. Die Leiste 13 weist eine Rampe 25 auf, welche die Hinterschneidung 15 von dem freien Ende des Schaftes 4 weg verjüngt.When inserting the key 1 in the lock channel 10, the control member 14 passes against the locking pin 16. Since the undercut 15 tapers by the shape of the control member 14, the locking pin 16 is pulled into the lock channel 10 and out of the pocket 17 of the housing 7 out , This is the movement of the core 8 opposite released the housing 7. This position of the control member 14 and the locking pin 16 is shown greatly enlarged in Figure 3. It can be seen that a radial widening 19 of the locking pin 16, which is held in the undercut 15, is limited by a constriction 20 of the locking pin 16. The locking pin 16 and the control member 14 also form a stop when inserting the key 1 in the lock channel 10. The control member 14 having bar 13 has a pin 21, with which it is pressed in a recess 22 of the key 1. When pulling out the key 1 from the lock channel 10, the wave-shaped elevation reaches 18 against the locking pin 16 and pushes it into the pocket 17 of the housing 7. Thus, the movement of the core 8 is blocked again. In one embodiment, not shown, the locking pin 16 may be biased with a spring element in the pocket 17 of the housing 2. The strip 13 has a ramp 25 which tapers the undercut 15 away from the free end of the shaft 4.

Figur 4 zeigt eine Schnittdarstellung durch den Schlüssel 1 mit dem Sperrstift 16 aus Figur 3 entlang der Linie IV - IV. Hierbei ist zu erkennen, dass die Leiste 13 schmaler ist als die Nut 12 und mit einem Vorsprung 23 eine quer zur Längsachse des Schaftes 4 weisende zweite Hinterschneidung 24 begrenzt. In diese zweite Hinerschneidung 24 kann ein nicht dargestellter Profilfortsatz des Kerns 8 eingreifen.FIG. 4 shows a sectional view through the key 1 with the locking pin 16 from FIG. 3 along the line IV - IV. It can be seen here that the strip 13 is narrower than the groove 12 and with a projection 23 a transverse to the longitudinal axis of the shaft 4 pointing second undercut 24 limited.
