Abstract

The cylinder has a sprung housing pin (3) belonging to a core pin (7) which has a stop piece (4) restricting its displacement. The end surface of the housing pin, in the stop position lies inside the housing hole (5) near the core hole. The end surface of the housing pin forms the base of a cavity (6) into which the core pin fits in a locking position. The connection between the key (9) and the core pin has at least one sloping surface (14) for lifting the core pin out of the locking position into a release position. The head of the core pin has a V-shaped groove in the side of its outer surface. The protruding flank (14) on the front of the key forms part of a hooked tooth (15).

Description

Die Erfindung betrifft einen Schließzylinder und bzw. oder Flachschlüssel für den Schließzylinder mit einem in einer Bohrung eines Zylindergehäuses drehbaren Zylinderkern mit Schlüsselkanal sowie mit Kern- und Gehäusestiften, die als Zuhaltungen von Kerben bzw. Zahnungen an der Schlüsselbrust des Flachschlüssels aus einer die Drehung des Zylinderkernes blockierenden Sperrstellung in eine Freigabestellung verschiebbar sind, wobei der in den Schlüsselkanal hineinragende Teil mindestens eines Kernstiftes, insbesondere des der Öffnung des Schlüsselkanals zunächst liegenden Kernstiftes, an seiner Mantelfläche mit einer in Einschubrichtung des Schlüssels vorspringenden Flanke der Schlüsselbrust eine Eingriffsverbindung aufweist.The invention relates to a locking cylinder and or or flat key for the locking cylinder with a rotatable in a bore of a cylinder housing with a cylinder core key channel and with core and housing pins, which as tumblers of notches or serrations on the key face of the flat key from a rotation of the cylinder core blocking blocking position can be displaced into a release position, the part of at least one core pin projecting into the key channel, in particular the core pin initially lying at the opening of the key channel, having an engagement connection on its lateral surface with a flank of the key face projecting in the direction of insertion of the key.

Aus der AT 396 957 B ist ein Schlüssel bekannt, der im Bereich seiner Zahnung nächst der Schlüsselreide eine Kerbe aufweist, in die eine in Einschubrichtung vorspringende Flanke, insbesondere ein Haken hineinragt. Diese meist trogförmige Kerbe der Schlüsselzahnung wird durch den Haken teilweise überdeckt. Der Schlüssel ist infolge dieser Ausbildung nur schwer nachzuarbeiten. Die üblichen Schlüsselkopierfräsen reproduzieren einen falschen Schlüssel. Durch den Zahn wird das Drehmoment zwischen Schlüssel und Schließzylinder sehr gut übertragen, weil die wirksame Barthöhe im Schlüsselkanal jedenfalls die maximal mögliche Größe hat. Der Schlüssel wirkt ferner mit einem besonderen Schließzylinder dadurch zusammen, daß der Haken den zugeordneten Kernstift festhält und so verhindert, daß der Kernstift in eine Gehäuseausnehmung eintaucht und die Drehung des Zylinderkernes blockiert.A key is known from AT 396 957 B which has a notch in the area of its teeth next to the key chalk into which a flank, in particular a hook, projects in the direction of insertion. This mostly trough-shaped notch of the key teeth is partially covered by the hook. The key is difficult to rework as a result of this training. The usual key copy milling machines reproduce the wrong key. The torque between the key and the locking cylinder is transmitted very well through the tooth, because the effective bit height in the key channel is at least as large as possible. The key also interacts with a special locking cylinder in that the hook holds the assigned core pin and thus prevents the core pin from dipping into a housing recess and blocking the rotation of the cylinder core.

Die Erfindung zielt darauf ab, mit einem Schlüssel der beschriebenen Art eine zusätzliche Funktion bei einem speziellen Schließzylinder zu erreichen, nämlich einen in Sperrstellung in eine Gehäusebohrung eintauchenden Kernstift in die Freigabestellung zu bringen und den Kernstift in dieser festzuhalten. Dies wird dadurch erreicht, daß der dem Kernstift zugeordnete, gefederte Gehäusestift mit einem Anschlag zur Hubbegrenzung seines Verschiebungsweges ausgebildet ist, wobei die Stirnfläche des Gehäusestiftes in der Anschlagstellung im Inneren der Gehäusebohrung nahe der Kernbohrung liegt und die Stirnfläche des Gehäusestiftes den Boden einer Ausnehmung bildet, in die der Kernstift in der Sperrstellung eintaucht, und daß die Eingriffsverbindung zwischen Schlüssel und Kernstift mindestens eine Schrägfläche zum Anheben des Kernstiftes aus der Sperrstellung in die Freigabestellung aufweist. Beim Einschieben des richtigen Schlüssels hebt dessen Schrägfläche den Kernstift aus der Ausnehmung im Zylindergehäuse heraus und bringt ihn mit seiner Stirnfläche in die Teilungsfläche zwischen Zylinderkern und Zylindergehäuse. Dadurch kann der Schließzylinder gesperrt werden. Die Schrägfläche kann am Schlüssel im Bereich der vorspringenden Flanke einer Kerbe der Schlüsselbrust nächst der Schlüsselreide vorgesehen sein. Sie kann in technischer Umkehr auch am Kernstift oder sowohl an diesem als auch an der vorspringenden Flanke der Schlüsselbrust angeordnet sein. Es ist zweckmäßig, wenn im Kopfbereich des Kernstiftes seitlich in der Mantelfläche eine V-förmige Nut vorgesehen ist und die an der Schlüsselbrust angeordnete und dem Kernstift zugeordnete, in Einschubrichtung über eine Schlüsselkerbe vorspringende Flanke als Teil eines hakenähnlichen Zahnes mit einer in die Nut des Kernstiftes eingreifenden und den Kernstift anhebenden Schrägfläche ausgebildet ist. Die Nut kann auch als V-förmige Ringnut ausgebildet sein. Im Zusammenwirken mit dem hakenförmigen Zahn wird der Kernstift durch Auflaufen auf die Schrägfläche aufgegriffen und angehoben. Die Steigung der Schrägfläche und deren Länge ist so bemessen, daß der Hub des Kernstiftes der Tiefe der Ausnehmung im Zylindergehäuse entspricht.The invention aims to use a key of the type described to achieve an additional function in a special locking cylinder, namely to bring a core pin that is immersed in a locking position into a housing bore into the release position and to hold the core pin in this position. This is achieved in that the spring-loaded housing pin assigned to the core pin is designed with a stop for limiting the stroke of its displacement path, the end face of the housing pin lying in the stop position in the interior of the housing bore near the core bore and the end face of the housing pin forms the bottom of a recess into which the core pin is immersed in the locking position, and that the engagement connection between the key and the core pin has at least one inclined surface for lifting the core pin out of the locking position into the release position. When the correct key is inserted, its inclined surface lifts the core pin out of the recess in the cylinder housing and brings it with its end face into the dividing surface between the cylinder core and the cylinder housing. This allows the locking cylinder to be locked. The inclined surface can be provided on the key in the area of the projecting flank of a notch of the key face next to the key chalk. In technical reversal, it can also be arranged on the core pin or both on this and on the projecting flank of the key face. It is expedient if a V-shaped groove is provided in the head area of the core pin laterally in the lateral surface and the flank which is arranged on the key face and assigned to the core pin and projects in the insertion direction via a key groove as part of a hook-like tooth with a into the groove of the core pin engaging and lifting the core pin inclined surface is formed. The groove can also be designed as a V-shaped annular groove. In cooperation with the hook-shaped tooth, the core pin is picked up and raised by running onto the inclined surface. The slope of the inclined surface and its length is such that the stroke of the core pin corresponds to the depth of the recess in the cylinder housing.

Eine spezielle Ausführungsform ist dadurch gekennzeichnet, daß ein Taststift in einer Bohrung des Zylinderkernes verschiebbar gelagert ist, die in die Kernstiftbohrung einmündet und daß der Taststift von dem aus der Teilungslage in das Zylinderkerninnere eingeschobenen Kernstift aus dem Zylinderkern in eine Sperrstellung ausschiebbar ist, in der der Taststift in eine Gehäuseausnehmung eintaucht. Damit ist sichergestellt, daß eine Freigabe durch den hier in Rede stehenden Kernstift tatsächlich nur in einer einzigen Verschiebelage erfolgt. Wird Teilung nicht erreicht, dann blockiert der Zylinder, weil der Kernstift noch in die Ausnehmung eintaucht. Wird der Kernstift über die Teilung gehoben, dann drückt er den Taststift seitlich in eine Gehäuseausnehmung hinaus und der Zylinder ist neuerlich blockiert. Um ein sicheres Sperren zu gewährleisten ist es zweckmäßig, wenn der Kernstift in Ausschubrichtung aus dem Zylinderkern durch eine Feder vorgespannt ist.A special embodiment is characterized in that a stylus is slidably mounted in a bore of the cylinder core, which opens into the core pin bore and that the stylus from the core pin inserted from the division position into the interior of the cylinder core can be pushed out of the cylinder core into a locking position in which Immerses the stylus in a housing recess. This ensures that a release by the core pin in question is actually only in a single displacement position. If division is not achieved, the cylinder locks because the core pin is still immersed in the recess. If the core pin is lifted over the division, it pushes the stylus laterally into a housing recess and the cylinder is blocked again. In order to ensure safe locking, it is expedient if the core pin is biased by a spring in the direction of extension from the cylinder core.

In den Zeichnungen ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Fig. 1 zeigt.-einen Längsschnitt durch einen Teil eines Schließzylinders in der Sperrstellung, Fig. 2 den Schließzylinder nach Fig. 1 mit einem passenden Schlüssel in der Freigabestellung und Fig. 3 den Querschnitt zu Fig. 2.An exemplary embodiment of the subject matter of the invention is shown in the drawings. 1 shows a longitudinal section through part of a locking cylinder in the locked position, FIG. 2 shows the locking cylinder according to FIG. 1 with a suitable key in the release position and FIG. 3 shows the cross section to FIG. 2.

Ein Schließzylinder umfaßt ein Zylindergehäuse 1 mit einer Kernbohrung, in welcher ein Zylinderkern 2 drehbar gelagert ist. Fünf, sechs oder sieben Reihen von Kern- und Gehäusestiften sind bei üblichen Schließzylinderkernkonstruktionen in radialen Bohrungen verschiebbar angeordnet und werden aus einer Sperrstellung durch den passenden Schlüssel derart verdrängt, daß die jeweiligen Berührungsflächen der Kernstifte mit den Gehäusestiften in der Kernbohrungsfläche liegen. Die Verschiebung der Kern- und Gehäusestifte erfolgt durch die an der Schlüsselbrust angeordnete Zahnung bzw. durch die Kerben.A lock cylinder comprises a cylinder housing 1 with a core bore in which a cylinder core 2 is rotatably mounted. Five, six or seven rows of core and housing pins are slidably arranged in radial bores in conventional lock cylinder core designs and are displaced from a locked position by the appropriate key in such a way that the respective contact surfaces of the core pins with the housing pins lie in the core bore area. The core and housing pins are shifted by the teeth on the key face or by the notches.

Die erste Stiftzuhaltung ist in den Figuren dargestellt Sie weicht gemäß der Erfindung von dem oben beschriebenen klassischen Funktionsprinzip ab. Ein Gehäusestift 3 ist abgesetzt ausgeführt und wirkt mit einem Anschlag 4 zusammen. Dadurch ist der Hub innerhalb der Gehäusebohrung 5 begrenzt. Die Stirnfläche des Gehäusestiftes 3 liegt in der den maximalen Hub begrenzenden Anschlagstellung (z.B. Fig. 1) etwas gegenüber der Kernborung zurückversetzt und bildet den Boden einer Ausnehmung 6 in die der Kernstift 7 gemäß Fig. 1 eintaucht. Dadurch ist der Zylinderkern 2 im Zylindergehäuse gegen Verdrehen blockiert. Der Schließzylinder ist gesperrt.The first pin tumbler is shown in the figures. According to the invention, it deviates from the classic functional principle described above. A housing pin 3 is of a stepped design and interacts with a stop 4. The stroke within the housing bore 5 is thereby limited. The end face of the housing pin 3 is in the stop position limiting the maximum stroke (e.g. FIG. 1) set back somewhat from the core bore and forms the bottom of a recess 6 into which the core pin 7 is immersed according to FIG. 1. As a result, the cylinder core 2 is blocked in the cylinder housing against twisting. The locking cylinder is locked.

Der Kernstift 7 trägt seitlich - der Öffnung des Schlüsselkanals 8 zugewandt - als Formschlußelement zum Zwecke der Eingriffsverbindung mit einem Schlüssel 9 (Fig. 2) eine V-förmige Nut 10 mit einer Schrägfläche 11. Wie Fig. 3 zeigt, wirkt eine Feder 12 auf den Kernstift 7. Wenn kein Schlüssel 9 im Schlüsselkanal 2 steckt (Fig. 1), dann drückt die Feder 12 den Kernstift 7 aus dem Zylinderkern 2 heraus, bis der Kernstift 7 in die Ausnehmung 6 sperrend eingreift.The core pin 7 carries laterally - facing the opening of the key channel 8 - as a positive locking element for the purpose of the engagement connection with a key 9 (FIG. 2) a V-shaped groove 10 with an inclined surface 11. As shown in FIG. 3, a spring 12 acts the core pin 7. If there is no key 9 in the key channel 2 (FIG. 1), the spring presses 12 the core pin 7 out of the cylinder core 2 until the core pin 7 engages in the recess 6 in a locking manner.

Ein üblicher Schlüssel mit Kerben und Zähnen an der Schlüsselbrust wird beim Einschieben in den Schlüsselkanal 8 den Kernstift 7 und dem Gehäusestift 3 allenfalls noch tiefer in die Bohrung 5 hineindrücken. Der Schließzylinder kann in keiner dieser Stellungen gesperrt werden.A conventional key with notches and teeth on the key face will at most push the core pin 7 and the housing pin 3 even deeper into the bore 5 when it is inserted into the key channel 8. The lock cylinder cannot be locked in any of these positions.

Der richtige Schlüssel 9 verfügt im Bereich der Schlüsselkerbe 13 über eine in Einschubrichtung über die Schlüsselkerbe 13 vorspringende Flanke 14 auf einem hakenähnlichen Zahn 15, der die Schlüsselkerbe 13 teilweise überdeckt. Die Flanke 14 ist als Schrägfläche ausgebildet, die mit der Schrägfläche 11 des Kernstiftes 7 korrespondiert. Beim Einschieben des Schlüssels 9 in den Schlüsselkanal 8 gleiten die Schrägflächen 11 bis 14 aufeinander und der Kernstift 7 wird gegen die Kraft der Feder 12 angehoben. Wenn der richtige Schlüssel 9 vollständig eingeschoben ist (Fig. 2), dann entspricht der Hub der Tiefe der Ausnehmung 6. Somit liegt der Kernstift 7 zur Gänze innerhalb des Zylinderkernes 2, der nun im Gehäuse 1 gedreht werden kann (vorausgesetzt natürlich, daß die hier nicht dargestellten Zuhaltungen auf Teilung gebracht wurden). Der Kernstift 7 wird in seiner Freigabestellung festgehalten und es wird verhindert, daß er durch die Feder 12 in die Ausnehmung 6 oder eine zusätzliche Ausnehmung im Drehbereich des Kernstiftes 7 gedrückt wird. Ein üblicher Flachschlüssel würde den Kernstift 7 nach unten drücken, wobei der gefederte Gehäusestift 3 ebenfalls zurückweicht, ohne daß Teilung jemals erreichbar ist. Da der Kernstift 7 abgesetzt ausgeführt ist, kann der Zylinderkern 2 bei Erreichen der Teilung der nicht dargestellten Zuhaltungen zwar aus der Grundstellung geringfügig weggedreht werden. Eine weitere Drehung des Zylinderkernes 2 wird aber durch Anschlagen des abgesetzten Kernstiftbereichs 7 an der Bohrungswand der Gehäusebohrung 5 blockiert.In the area of the key notch 13, the correct key 9 has a flank 14 projecting in the insertion direction over the key notch 13 on a hook-like tooth 15 which partially covers the key notch 13. The flank 14 is designed as an inclined surface which corresponds to the inclined surface 11 of the core pin 7. When the key 9 is inserted into the key channel 8, the inclined surfaces 11 to 14 slide on one another and the core pin 7 is raised against the force of the spring 12. If the correct key 9 is fully inserted (Fig. 2), then the stroke corresponds to the depth of the recess 6. Thus, the core pin 7 lies entirely within the cylinder core 2, which can now be rotated in the housing 1 (provided, of course, that tumblers not shown here were brought to division). The core pin 7 is held in its release position and it is prevented that it is pressed by the spring 12 into the recess 6 or an additional recess in the rotating area of the core pin 7. A conventional flat key would press the core pin 7 down, the spring-loaded housing pin 3 also withdrawing without division ever being achievable. Since the core pin 7 is of stepped design, the cylinder core 2 can be turned slightly away from the basic position when the tumblers, not shown, are reached. A further rotation of the cylinder core 2 is blocked by striking the stepped core pin region 7 on the bore wall of the housing bore 5.

Der Kernstift 7 ist infolge seiner Federung und des exzentrischen Mitnehmerstiftes 16 drehfest geführt. In der Fig. 3 ist ein Taststift 17 dargestellt, der in einer Querbohrung zum Schlüsselkanal 8 liegt und der bei über die Teilungsfläche angehobenem Kernstift 7 von diesem nach außen verdrängt wird. Der Taststift 17 greift dann in eine Gehäuseausnehmung 18 sperrend ein. Die Bohrung für den Taststift 17 kann schräg zur Drehachse des Zylinderkernes 2 ausgeführt sein, damit der Taststift 17 beim Sperrvorgang nicht in die Ausnehmung 6 gleitet. Dies kann auch dadurch verhindert werden, daß der Taststift 17 in Richtung auf den Schlüsselkanal 8 gefedert ist. Der Taststift 17 kann zylindrisch oder im Bereich seines Eingriffs auch als quaderförmiger Schieber ausgebildet sein.The core pin 7 is rotatably guided due to its suspension and the eccentric driver pin 16. 3 shows a stylus 17 which lies in a transverse bore to the key channel 8 and which, when the core pin 7 is raised above the dividing surface, displaces it outwards becomes. The stylus 17 then engages in a recess 18 in the housing. The bore for the stylus 17 can be made obliquely to the axis of rotation of the cylinder core 2 so that the stylus 17 does not slide into the recess 6 during the locking process. This can also be prevented in that the stylus 17 is sprung in the direction of the key channel 8. The stylus 17 can be cylindrical or in the area of its engagement as a cuboid slide.
