Abstract

In order to provide an additional possibility of variation for the flat key 5 of a cylinder lock 1, blocking pins 9 are provided which are attached in the cylinder housing 2. Said blocking pins project inside the cylinder housing 2 into an annular groove 10 of the cylinder core 3. In order to be able to rotate the cylinder core 3 despite these blocking pins 9, a fitting key 5 with a corresponding notching 12 must be used. After correct positioning of the key 5 in the cylinder lock 1, this notching 12 comes to rest exactly in the annular groove 10 so that the key 5 can be moved past the blocking pins 9 without impedance. <IMAGE>

Description

Die Erfindung betrifft ein Drehzylinderschloß mit einem Zylindergehäuse und einem darin drehbar gelagerten, einem Schlüsselkanal zur Aufnahme des Schlüssel mit wenigstens einer Einkerbung an seiner Rückseite aufweisenden Zylinderkern, der an seiner äußeren Mantelfläche mit wenigstens einer Ringnut versehen ist.The invention relates to a rotary cylinder lock with a cylinder housing and a rotatably mounted therein, a key channel for receiving the key with at least one notch on the back of the cylinder core, which is provided on its outer surface with at least one annular groove.

Es ist - gemäß DE-PS 2 548 202 - bereits ein Drehzylinderschloß mit einem Zylindergehäuse und einem darin drehbar gelagerten Zylinderkern mit einem Schlüsselkanal zur Aufnahme eines Flachschlüssels bekannt. Im Zylinderkern sind Kernstife und im Zylindergehäuse Gehäusestifte durch Federdruck radial verschiebbar gelagert. Der Zylinderkern weist an seiner Außenfläche Ringnuten auf, die durch entsprechende Einkerbungen am Schlüsselrücken ergänzbar sind. Mit Hilfe dieser Ringnuten wird eine Kupplung eines Gehäusestiftes mit einem Kernstift herbeigeführt.According to DE-PS 2 548 202, a rotary cylinder lock with a cylinder housing and a cylinder core rotatably mounted therein with a key channel for receiving a flat key is already known. Core pins are located in the cylinder core and housing pins in the cylinder housing are radially displaceable by spring pressure. The cylinder core has annular grooves on its outer surface, which can be supplemented by corresponding notches on the spine of the key. With the help of these ring grooves, a coupling of a housing pin with a core pin is brought about.

Es ist auch - gemäß DE-OS 3 004 992 - bekannt, zwecks Profilvariation von Drehzylinderschlössern am Rücken eines Flachschlüssels in dessen Längsrichtung verlaufende Nuten anzubringen. Im Zylinderkern sind quer verlaufende Schlitze zur Aufnahme von Scheiben vorgesehen, die ein dem Querschnittsprofil des Schlüsselrückens entsprechendes Durchgangsprofil aufweisen. Wird nun ein Schlüssel mit einem abweichenden Querschnittsprofil verwendet, so kann der Schlüssel nicht in den Schlüsselkanal eingeführt werden. Eine derartige bekannte Ausführung zur Vergrößerung der Profilvariation ist relativ aufwendig und hat außerdem den Nachteil, daß die Breite des Schlüsselrückens für in dessen Längsrichtung verlaufende Nuten sehr gering ist.It is also known - according to DE-OS 3 004 992 - to make grooves in the longitudinal direction of the flat key in order to vary the profile of rotary cylinder locks. Transversely extending slots are provided in the cylinder core for receiving disks, which have a through profile corresponding to the cross-sectional profile of the spine of the key. If a key with a different cross-sectional profile is now used, the key cannot be inserted into the key channel. Such a known design for increasing the profile variation is relatively complex and also has the disadvantage that the width of the spine of the key for grooves running in its longitudinal direction is very small.

Schließlich ist noch - gemäß DE-OS 2 809 351 - ein anderes Drehzylinderschloß mit einem Flachschlüssel bekannt der am Schlüsselrücken Einkerbungen aufweist, die mit den Gehäusestiften in Wirkverbindung stehen.Finally, according to DE-OS 2 809 351, another rotary cylinder lock with a flat key is known which has notches on the key back which are operatively connected to the housing pins.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Drehzylinderschlosses der eingangs beschriebenen Art, das mit nur geringem konstruktiven Mehraufwand eine Vergrößerung der Schlüssel- Profilvariation ermöglicht.The object of the present invention is now to provide a rotary cylinder lock of the type described in the introduction, which enables the key profile variation to be enlarged with only little additional construction effort.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der entriegelten Position des Zylinderkerns wenigstens an einer Seite des Schlüsselkanals jeweils wenigstens ein Sperrstift am Zylindergehäuse befestigt ist, wobei das innere Ende jedes Sperrstiftes in die Ringnut des Zylinderkerns hineinragt und die Breite der Einkerbung am Schlüsselrücken geringfügig großer als die Breite bzw. Dicke des Sperrstiftes ausgebildet ist. Auf diese Weise liegt zusätzlich zum Profilverlauf des Schlüsselbartes und der Sperrsicherung von Gehäuse- und Zylinderstiften eine weitere Profilvariation des Schlüssels vor, die mit lediglich geringem konstruktiven Mehraufwand verbunden ist. Mit der Anordnung eines derartigen Sperrstiftes kann der Zylinderkern nur geringfügig bis zur Anlage des nicht passenden Schlüsselrückens an den Sperrstift bzw. nach der anderen Drehrichtung nur um eine volle Drehung ebenfalls bis zur Anlage an den Sperrstift verdreht werden. Mit dieser erfindungsgemäßen Ausführung ist außerdem noch der Vorteil verbunden, daß die gesamte Länge des Schlüsselrückens für die Einkerbung zur Verfügung steht, sodaß allein schon in Bezug auf den Abstand der Einkerbung zur Schlüsselbrust eine große Anzahl von Variationen offen steht. Eine weitere Variationsmöglichkeit besteht auch noch in der Form der Einkerbung, der zugeordneten Ringnut, sowie dem in diese hineinragenden Sperrstift. Diese Form kann im Querschnitt z.B. trapez-, halbkreis-, V-förmig oder dergleichen ausgebildet sein.This object is achieved in that in the unlocked position of the cylinder core at least on one side of the key channel at least one locking pin is attached to the cylinder housing, the inner end of each locking pin protruding into the annular groove of the cylinder core and the width of the notch on the spine of the key slightly larger is designed as the width or thickness of the locking pin. In this way, in addition to the profile profile of the key bit and the locking device for the housing and cylinder pins, there is a further profile variation of the key, which is associated with only a small additional design effort. With the arrangement of such a locking pin, the cylinder core can only be rotated slightly until it comes into contact with the back of the key that does not match the locking pin or, in the other direction of rotation, only by one full turn until it contacts the locking pin. This embodiment of the invention also has the advantage that the entire length of the key spine is available for the notch, so that a large number of variations are already available in relation to the distance between the notch and the key face. Another variation is also in the shape of the notch, the associated ring groove, and the locking pin protruding into it. This shape can e.g. be trapezoidal, semicircular, V-shaped or the like.

Eine weitere bevorzugte Ausführungsvariante der Erfindung besteht auch darin, daß mehrere Einkerbungen am Schlüsselrücken sowie eine gleiche Anzahl von Ringnuten im Zylinderkern vorgesehen sind, wobei jeder Ringnut wenigstens ein Sperrstift zugeordnet ist. Mit einer Vielzahl von derartigen Einkerbungen und mit diesen zusammenwirkenden Ringnuten und Sperrstifen kann die Variationsmöglichkeit noch zusätzlich beträchtlich gesteigert werden. Damit entfällt auch die Möglichkeit, daß durch probeweises Einfeilen von Einkerbungen in einen Schlüsselrücken die Sperrstifte umgangen werden können.Another preferred embodiment of the invention also consists in the fact that several notches are provided on the spine of the key and an equal number of ring grooves in the cylinder core, each ring groove being assigned at least one locking pin. With a variety of such notches and with these cooperating ring grooves and locking pins, the possibility of variation can also increase considerably be tied. This also eliminates the possibility that the locking pins can be bypassed by trial-filing notches in a key spine.

Gemäß einer-weiteren-vorteilhaften Ausführungsform der Erfindung ist vorgesehen, daß jeweils pro Ringnut zwei beidseits des Schlüsselkanals angeordnete Sperrstifte vorgesehen sind. Mit einer derartigen Doppelsicherung kann der Zylinderkern überhaupt nicht mehr bewegt werden, sodaß auch bei einem Schnappschloß, daß nicht verriegelt wurde, die Falle zum Öffnen der Tür blockiert ist.According to a further advantageous embodiment of the invention it is provided that two locking pins arranged on each side of the key channel are provided for each annular groove. With such a double lock, the cylinder core can no longer be moved, so that even with a snap lock that has not been locked, the latch for opening the door is blocked.

Entsprechend einer anderen bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß am Schlüsselrücken mehrere unterschiedlich tiefe Einkerbungen vorgesehen sind, denen jeweils eine die entsprechende gleiche Tiefe aufweisende Ringnut und wenigstens ein entsprechend lang ausgebildeter Sperrstift zugeordnet ist. Mit dieser unterschiedlich tiefen Ausbildung der Einkerbungen, Ringnuten und den unterschiedlich langen Sperrstiften ist eine zusätzliche Variationsmöglichkeit gegeben, sodaß die Einbruchsicherheit mit der erfindungsgemäßen Ausführung eines Drehzylinderschlosses wesentlich erhöht ist.According to another preferred embodiment of the invention it is provided that several notches of different depths are provided on the spine of the key, each of which is assigned an annular groove of the same depth and at least one correspondingly long locking pin. With this different depth formation of the notches, ring grooves and the locking pins of different lengths, there is an additional possibility of variation, so that the security against burglary is significantly increased with the design of a rotary cylinder lock according to the invention.

Schließlich ist noch entsprechend einer weiteren Ausführungsvariante der Erfindung vorgesehen, daß die Längsrichtung der Einkerbung am Schlüsselrücken schräg zur Längsrichtung des Schlüssels verlaufend ausgebildet ist. Auch mit dieser schrägen Lage der Einkerbung, die natürlich eine entsprechend Schräglage der Ringnut und der Sperrstifte erfordert, ist die Wahrscheinlichkeit eines unbefugten Öffnens des Schlosses durch versuchsweises Einfeilen von Einkerbungen am Schlüsselrücken praktisch auf null reduziert, da zusätzlich zum Abstand der Einkerbung zur Schlüsselbrust auch noch die Tiefe sowie der Winkel zur Schlüssellängsrichtung erraten werden müßte.Finally, according to a further embodiment variant of the invention, it is provided that the longitudinal direction of the notch on the back of the key is formed obliquely to the longitudinal direction of the key. Even with this inclined position of the notch, which of course requires a correspondingly inclined position of the ring groove and the locking pins, the probability of unauthorized opening of the lock is practically reduced to zero by trial-filing notches on the spine of the key, because in addition to the distance between the notch and the key face the depth and the angle to the key longitudinal direction would have to be guessed.

Im folgenden wird die Erfindung an Hand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. Dabei zeigen:

  • Fig. 1 eine Seitenansicht eines Doppel-Drehzylinderschlosses;
  • Fig. 2, 3 und 4 jeweils einen Querschnitt durch ein erfindungsgemäß ausgebildetes Drehzylinderschloß mit entsprechendem Schlüssel und
  • Fig. 5 eine Seitenansicht eines weiteres Schlüsselausführungsbeispieles gemäß der Erfindung.
The invention is described in more detail below with reference to exemplary embodiments shown in the drawing. Show:
  • Fig. 1 is a side view of a double rotary cylinder lock;
  • 2, 3 and 4 each show a cross section through an inventive rotary cylinder lock with a corresponding key and
  • Fig. 5 is a side view of another key embodiment according to the invention.

Ein in Fig. 1 ersichtliches Drehzylinderschloß 1 besteht in an sich bekannter Weise aus einem Zylindergehäuse 2, einem Zylinderkern 3 mit einem Schlüsselkanal 4 zur Aufnahme eines Flachschlüssels 5. Kern- und Zylinderstifte 6 bzw. 7 sind in entsprechenden Bohrungen verschiebbar gelagert und werden durch den Druck von Schraubenfedern 8 gegen den Schlüsselbart gedrückt.A rotary cylinder lock 1 shown in Fig. 1 consists in a conventional manner of a cylinder housing 2, a cylinder core 3 with a key channel 4 for receiving a flat key 5. Core and cylinder pins 6 and 7 are slidably mounted in corresponding holes and are through the Pressure of coil springs 8 pressed against the key bit.

Wie insbesondere auch in den Fig. 2, 3 und 4 ersichtlich, sind am Zylindergehäuse - bei entriegelter Position des Schlüssels beidseits des Schlüsselkanals 4 - Sperrstifte 9 befestigt. Diese sind in eine Bohrung des Zylindergehäuses 2 gesteckt und ragen mit ihrem radial inneren Ende in eine Ringnut 10 des Zylinderkernes 3. Diese Ringnut 10 ist geringfügig breiter als die Sperrstifte 9 ausgebildet, sodaß trotz der vorstehenden Sperrstifte 9 eine ungehinderte Drehbewegung des Zylinderkernes möglich ist. Für eine derartige ungehinderte Drehung des Zylinderkernes 3 ist es jedoch unbedingt erforderlich, daß der Schlüssel 5 im Bereich seines Schlüsselrückens 11 eine Einkerbung 12 aufweist. Der Abstand dieser Einkerbung 12 von der Schlüsselbrust 13 entspricht dem Abstand der Ringnut 10 vom Anschlag 14 des Zylinderkernes 3. Die Länge der Einkerbung 12 ist geringfügig größer als die Dicke der Sperrstifte 9 ausgebildet.As can also be seen in particular in FIGS. 2, 3 and 4, locking pins 9 are attached to the cylinder housing 4 when the key is unlocked on both sides of the key channel 4. These are inserted into a bore of the cylinder housing 2 and protrude with their radially inner end into an annular groove 10 of the cylinder core 3. This annular groove 10 is slightly wider than the locking pins 9, so that an unimpeded rotational movement of the cylinder core is possible despite the above locking pins 9. For such an unimpeded rotation of the cylinder core 3, however, it is absolutely necessary that the key 5 has a notch 12 in the area of its key back 11. The distance of this notch 12 from the key face 13 corresponds to the distance of the annular groove 10 from the stop 14 of the cylinder core 3. The length of the notch 12 is slightly larger than the thickness of the locking pins 9.

Wie in Fig. 2 ersichtlich, kann der Zylinderkern 3 mit Hilfe des in den Schlüsselkanal 4 eingeführten Schlüssels 5 ohne Behinderung durch die Sperrstifte 9 gedreht werden, da durch die in der Ringnut 10 positionierte Einkerbung 12 des Schlüssels 5 kein Anschlag an die Sperrstifte 9 möglich ist.As can be seen in FIG. 2, the cylinder core 3 can be rotated with the help of the key 5 inserted into the key channel 4 without hindrance by the locking pins 9, since the notch 12 of the key 5 positioned in the annular groove 10 means that no stop on the locking pins 9 is possible is.

Anders ist die Situation in der Ausführung gemäß Fig. 3, bei der ein Schlüssel ohne Einkerbung am Schlüsselrücken verwendet wird. Bei Drehung des Zylinderkernes 3 durch einen derartigen Schlüssel 5 kommt es zu einem Anschlag des Schlüsselrückens 11 an den Sperrstift 9, sodaß ein Weiterdrehen und Öffnen ausgeschlossen ist. Die in Fig. 4 dargestellte Ausführung zeigt deutlich, daß eine gänzliche Entfernung des Schlüsselrückens 11 zur Vermeidung eines Anschlages an die Sperrstifte 9 nicht zielführend ist, da mit dieser Lösung nach halber Drehung des Zylinderkernes 3 eine Sperrung durch die Kern- und Gehäusestifte 6, 7 erfolgt.The situation in the embodiment according to FIG. 3 is different who uses a key without a notch on the back of the key. When the cylinder core 3 is rotated by such a key 5, the back of the key 11 stops against the locking pin 9, so that further turning and opening is excluded. The embodiment shown in Fig. 4 clearly shows that a complete removal of the key spine 11 to avoid a stop on the locking pins 9 is not expedient, since with this solution after a half rotation of the cylinder core 3 a locking by the core and housing pins 6, 7th he follows.

Im Schlüsselrücken 11 des in Fig. 5 dargestellten Schlüssels 5 sind verschiedene mögliche Ausführungsformen der Einkerbungen 12 angeführt. Abweichend von dieser Ausführung können natürlich mehrere Einkerbungen 12 der gleichen Art hintereinander vorgesehen sein.Various possible embodiments of the notches 12 are given in the key back 11 of the key 5 shown in FIG. 5. In a departure from this embodiment, a plurality of notches 12 of the same type can of course be provided in succession.
