Description

Die Erfindung betrifft einen Schließzylinder, mit einem im Schließzylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zum Einführen eines Flachschlüssels aufweist und der eine durch den Schlüssel aktivierbare Kupplung aufweist, die die Drehverbindung des Zylinderkerns mit einem Abtrieb herstellt.The invention relates to a lock cylinder, with a cylinder core rotatably mounted in the lock cylinder housing, which has a keyway for inserting a flat key and which has a clutch which can be activated by the key, which produces the rotary connection of the cylinder core with an output.

Ein solcher Schließzylinder ist zum Beispiel aus US 2006/0156771 A1 und EP 1 717 761 A2 bekannt.Such a lock cylinder is for example off US 2006/0156771 A1 and EP 1 717 761 A2 known.

Es ist ein sehr großer Aufwand erforderlich, um die Kernposition bei rein elektronischen Zylindern gegen Verdrehen zu sichern (siehe DIN 1303: bis zu 30Nm), wenn man ein Design mit fester Kernposition wählt.It takes a very great effort to secure the core position against rotation with purely electronic cylinders (see DIN 1303: up to 30Nm), if one chooses a design with fixed core position.

Aufgabe der Erfindung ist es, einen Schließzylinder bereitzustellen, der einen vereinfachten Aufbau, einen hohen Manipulationsschutz und auch Kernziehschutz aufweist,The object of the invention is to provide a lock cylinder which has a simplified structure, a high protection against manipulation and also core pull protection,

Gelöst wird diese Aufgabe erfindungsgemäß mit einem Schließzylinder, mit einem im Schließzylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zum Einführen eines Flachschlüssels aufweist und der eine durch den Schlüssel aktivierbare Kupplung aufweist, die die Drehverbindung des Zylinderkerns mit einem Abtrieb herstellt. der dadurch gekennzeichnet ist,

  • dass in der Stirnseite des Schließzylindergehäuses ein Kernkopf drehbar angeordnet ist,
  • dass der Zylinderkern gegenüber dem Kernkopf frei drehbar hinter dem Kernkopf angeordnet ist,
  • dass im Zylinderkern ein Elektroantrieb angeordnet ist, mit dessen Hilfe Kupplungselemente in einen Formschluss mit dem Abtrieb bringbar sind, um die Drehverbindung zwischen Zylinderkern und Abtrieb herzustellen,
  • und dass die Aktivierung des Elektroantriebes durch den in den Schlüsselkanal eingeführten Schlüssel erfolgt,
  • und dass der Schlüssel Kernkopf und Zylinderkern drehfest miteinander verbindet.
This object is achieved according to the invention with a lock cylinder, with a cylinder core rotatably mounted in the lock cylinder housing, which has a keyway for inserting a flat key and having an activatable by the key coupling that produces the rotational connection of the cylinder core with an output. which is characterized
  • a core head is rotatably arranged in the end face of the lock cylinder housing,
  • the cylinder core is freely rotatable behind the core head in relation to the core head,
  • that in the cylinder core, an electric drive is arranged, with the aid of coupling elements can be brought into positive engagement with the output in order to produce the rotational connection between the cylinder core and output,
  • and that the activation of the electric drive is effected by the key inserted into the key channel,
  • and that the key core head and cylinder core rotatably connected.

Der Mechanismus am vom Elektroantrieb abgewandten Ende der Spindel kann als konischer Schieber ausgebildet sein, mit dessen Hilfe Kugelelemente radial in den Formschluss mit dem Abtrieb bringbar sind, wobei der Abtrieb der Schließbartring ist.The mechanism on the end remote from the electric drive end of the spindle can be designed as a conical slider, with the help of ball elements can be brought radially into positive engagement with the output, the output of the Schließbartring.

In einer weiteren Ausführungsform kann der Antrieb ein Elektromagnet sein, der den konischen Schieber zwischen seinen beiden Endpositionen bewegt.In another embodiment, the drive may be an electromagnet that moves the conical slider between its two end positions.

Weiterhin ist eine Ausführung denkbar, bei der die Kugeln magnetisch sind und dadurch ständig am magnetischen Abtrieb (Schließbartring) anliegen. Jetzt kann der Schieber lastfrei um nur 90° gedreht werden, um die Kupplungsposition zu erreichen.Furthermore, a design is conceivable in which the balls are magnetic and thereby constantly abut the magnetic output (Schließbartring). Now the slider can be rotated without load by only 90 ° to reach the coupling position.

Die Energiequelle für die Elektronik und den Antrieb ist wahlweise im Zylindergehäuse oder im Schlüssel untergebracht. Bei Anordnung der Energiequelle im Zylindergehäuse ist sie von der Gehäusestirnseite (Türaußenseite) her erreichbar angeordnet.The power source for the electronics and the drive is housed either in the cylinder housing or in the key. When arranging the power source in the cylinder housing, it is arranged accessible from the housing front side (outside of the door).

Gemäß einer Weiterbildung der Erfindung weist der Kernkopf eine Rastung auf, die als Schlüsselabzugssicherung bzw. Schlüsselabzugspositionierung dient.According to one embodiment of the invention, the core head on a detent, which serves as a key trigger security or key withdrawal positioning.

Vorzugsweise weist auch der Schließbart eine Rastung auf, die ihn in der Kupplungsposition arretiert.Preferably, the cam has a detent that locks it in the coupling position.

Vorzugsweise ist im Zylinderkern eine Auswerteelektronik angeordnet ist, die den Schlüsselcode prüft und bei passender Zugangsberechtigung den Elektroantrieb aktiviert.Preferably, an evaluation is arranged in the cylinder core, which checks the key code and activates the electric drive with appropriate access authorization.

Es gibt bisher kein Schließsystem, dass einen frei drehenden Zylinderkern hat; d.h. wo der Zylinderkern so lange frei drehend bleibt, bis mit einem berechtigten Schlüssel der Zylinderkern an den Schließbart gekuppelt wird. Dabei trägt der Schlüssel eine elektronische Codierung und die Spannungsversorgung für den im Kern befindlichen kuppelnden, elektromechanischen Mechanismus, sofern diese nicht im Zylindergehäuse untergebracht ist.So far, there is no locking system that has a freely rotating cylinder core; i.e. where the cylinder core remains free to rotate until it is coupled with an authorized key of the cylinder core to the cam. The key carries an electronic coding and the power supply for the core located coupling, electromechanical mechanism, unless it is housed in the cylinder housing.

Hier kann noch angefügt werden, dass der Schlüssel trotzdem (obwohl der Kern frei drehend ist) nur horizontal oder vertikal in den Kern eingeführt werden kann (Abzugsposition). Dies kann mittels einer Kugelrastung einfach erreicht werden. Der Schließkanal kann zentrisch zum Kern sein, oder exzentrisch.Here it can be added that the key can still be inserted horizontally or vertically into the core (although the core is freely rotating) (trigger position). This can be easily achieved by means of a ball catch. The closing channel can be centric to the core, or eccentric.

Die Erfindung soll nachfolgend mit Bezug auf ein in den Zeichnungen dargestelltes Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail with reference to an exemplary embodiment illustrated in the drawings.

Figur 2 zeigt einen Schnitt durch das Schließzylindergehäuse 3 und den in den Schlüsselkanal des Zylinderkerns eingeführten Schlüssel 1. Der Zylinderkern ist unterteilt in den Kernkopf 6, der keine Verbindung zum eigentlichen Zylinderkern 7 hat. Hergestellt wird die Verbindung erst durch den in den Schlüsselkanal eingeführten Schlüssel. Im Zylinderkern 7 ist die Elektronik 8 zur Prüfung der Zugangsberechtigung unter gebracht. Vor dem Antrieb 9 kann noch ein Bohrschutz 20 positioniert sein. FIG. 2 shows a section through the lock cylinder housing 3 and introduced into the keyway of the cylinder core key 1. The cylinder core is divided into the core head 6, which has no connection to the actual cylinder core 7. The connection is made only by the key inserted in the keyway. In the cylinder core 7, the electronics 8 is brought to check the access authorization. Before the drive 9, a drill protection 20 can still be positioned.

Ein Antrieb 9 ist drehfest im Zylinderkern 7 angeordnet und - bei dem gezeigten Ausführungsbeispiel - mit einer Gewindespindel 10 versehen, auf der ein konischer Schieber 11 vor und zurück bewegt werden kann. In der Figur 2 ist der Schieber 11 nach vorne in Mitnahmeposition gefahren. Der Schieber drückt zwei in dem Zylinderkern 7 angeordnete Kugeln 12 nach außen an den Schließbartring 5. Der Schließbartring hat entsprechende Ausnehmungen 13, um eine Drehmomentübertragung vom Zylinderkern oder besser gesagt, vom Schlüssel auf den Schließbartring zu ermöglichen.A drive 9 is non-rotatably arranged in the cylinder core 7 and - in the embodiment shown - provided with a threaded spindle 10 on which a conical slider 11 can be moved back and forth. In the FIG. 2 the slider 11 has moved forward in driving position. The slider pushes two arranged in the cylinder core 7 balls 12 outwardly to the Schließbartring 5. The Schließbartring has corresponding recesses 13 to allow torque transmission from the cylinder core or rather, the key on the Schließbartring.

Eine Rastung mittels Kugel 18 und Senkung im Schlüsselschaft 19 ermöglicht eine einfache Schlüsselabzugssicherung, bzw. Schlüsselabzugsposition und auch Sicherung vor falschen Schlüsseln (Senkung an falscher Position oder in falscher Tiefe). Bei abgezogenem Schlüssel wird die Kugel durch die gefederte Stiftkombination 16,17 in Richtung Schließkanal gedrückt und die Verdrehung des Kernkopfes 6 verhindert.A detent by means of ball 18 and lowering in the key shank 19 allows a simple key withdrawal protection, or key withdrawal position and also protection against false keys (lowering in the wrong position or in the wrong depth). When the key is removed, the ball is pressed by the spring-loaded pin combination 16,17 in the direction of the closing channel and prevents the rotation of the core head 6.
