Description
Die Erfindung betrifft eine Schließeinrichtung, insbesondere Schließzylinder, mit einem in einem Gehäuse gelagerten Kern, mit einem Sperrmechanismus zur Erzeugung eines Formschlusses zwischen dem Gehäuse und dem Kern, mit einem Schließbart und mit einer Kupplung zur wahlweisen Erzeugung oder Lösung eines Formschlusses des Schließbartes mit dem Kern und mit Mitteln zur Einleitung eines Drehmoments in den Kern, wobei die Kupplung ein in den Bewegungsbereich des Kerns und des Schließbartes eindringendes Formschlusselement zur Erzeugung eines Formschlusses aufweist, wobei der Formschluss der Kupplung auf einen vorgesehenen Winkelbereich begrenzt ist und die Kupplung über den vorgesehenen Winkelbereich einen Freilauf hat und wobei die wahlweise Erzeugung oder Lösung des Formschlusses der Kupplung abhängig von dem Winkelbereich des Kerns ist, so dass sich der Schließbart durch eine entsprechend weite Drehung des Kerns antreiben lässt, jedoch die Kupplung einen Freilauf über zumindest den Winkelbereich gewährleistet.The invention relates to a locking device, in particular lock cylinder, with a core mounted in a housing, with a locking mechanism for generating a positive connection between the housing and the core, with a cam and with a clutch for selectively generating or solving a positive connection of the cam with the core and means for introducing a torque into the core, wherein the coupling has a positive engagement element penetrating into the movement region of the core and the lock bit to produce a positive connection, wherein the positive connection of the coupling is limited to an intended angle range and the coupling over the intended angular range Freewheel has and wherein the optional generation or solution of the positive connection of the coupling is dependent on the angular range of the core, so that the cam can be driven by a correspondingly wide rotation of the core, but the clutch over a freewheel over guaranteed the angle range.

Bei Anti-Panik Schließeinrichtungen ist es jedoch erforderlich, dass in einer der Nichtbetätigung entsprechenden Grundstellung des Schließzylinders der Schließbart eine Freilauffunktion aufweist, so dass der Schließbart ohne Ansteuerung des Sperrmechanismus bewegt werden kann.In anti-panic locking devices, however, it is necessary that in a non-actuation corresponding basic position of the lock cylinder, the cam has a freewheeling function, so that the cam can be moved without activation of the locking mechanism.
Der Erfindung liegt das Problem zugrunde, eine Schließeinrichtung der eingangs genannten Art so weiter zu bilden, dass eine Freilauffunktion des Schließbartes in Grundstellung zuverlässig gewährleistet ist.The invention is based on the problem, so to form a locking device of the type mentioned so that a freewheeling function of the cam in the basic position is reliably guaranteed.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Kern oder der Schließbart eine Führung für das Formschlusselement aufweist, wobei das Formschlusselement in Drehrichtung einen Formschluss in der Führung hat und in Abhängigkeit von dem Winkelbereich radial nach innen oder nach außen über die Begrenzung der Führung bewegbar ist.This problem is inventively solved in that the core or the cam has a guide for the positive locking element, wherein the positive locking element has a positive connection in the direction of rotation in the guide and is movable depending on the angular range radially inwardly or outwardly beyond the limitation of the guide ,
Durch diese Gestaltung ist die wahlweise Erzeugung oder Lösung des Formschlusses der Kupplung abhängig von dem Winkelbereich des Kerns. Damit lässt sich der Schließbart durch eine entsprechend weite Drehung des Kerns antreiben. Jedoch gewährleistet die Kupplung auch einen Freilauf über zumindest den Winkelbereich. Damit kann der Schließbart unabhängig von dem Kern angetrieben werden, um die Anti-Panik Funktion zu erzeugen. Die Mittel zur Einleitung eines Drehmoments sind bei gängigen Schließeinrichtungen meist ein Knauf oder ein Schließkanal zum Einführen eines Schlüssels. Die Lösung oder Erzeugung des Formschlusses zwischen dem Kern und dem Schließbart in Abhängigkeit von dem Winkelbereich gestaltet sich konstruktiv besonders einfach, weil der Kern oder der Schließbart eine Führung für das Formschlusselement aufweist, wobei das Formschlusselement in Drehrichtung einen Formschluss in der Führung hat und in Abhängigkeit von dem Winkelbereich radial nach innen oder nach außen über die Begrenzung der Führung bewegbar ist. Durch diese Gestaltung kann das Formschlusselement aus der Führung radial herausragen und damit einen Formschluss mit dem jeweils anderen Bauteil des Kerns oder des Schließbartes erzeugen. Da jedoch das Formschlusselement in Abhängigkeit von dem Winkelbereich in die Führung zurückbewegbar ist, kann der Formschluss zwischen Kern und Schließbart einfach gelöst werden.By this design, the optional generation or solution of the positive connection of the coupling is dependent on the angular range of the core. Thus, the cam can be driven by a correspondingly wide rotation of the core. However, the clutch also ensures a freewheel over at least the angular range. Thus, the cam can be driven independently of the core to produce the anti-panic function. The means for introducing a torque are usually a knob or a closing channel for insertion of a key in common locking devices. The solution or generation of the positive connection between the core and the cam as a function of the angular range is structurally particularly simple because the core or the cam has a guide for the positive locking element, wherein the positive locking element in the direction of rotation has a positive connection in the guide and in dependence from the angular range radially inwardly or outwardly beyond the boundary of the guide is movable. By virtue of this configuration, the positive-locking element can protrude radially out of the guide and thus produce a positive connection with the respective other component of the core or of the locking bit. However, since the interlocking element is movable back into the guide depending on the angular range, the positive connection between the core and cam can be easily solved.
Die Begrenzung des Formschlusses auf den vorgesehenen Winkelbereich gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Kupplung Mittel zur Entfernung des Formschlusselementes aus dem Bewegungsbereich des Kerns oder des Schließbartes nach dem vorgesehenen Winkelbereich hat.The limitation of the positive locking on the intended angular range designed according to another advantageous embodiment of the invention is particularly simple if the coupling has means for removing the positive locking element from the range of motion of the core or the cam after the intended angle range.
Zur Vereinfachung der Lösung des Formschlusses nach dem vorgesehenen Winkelbereich trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die Mittel eine in einem feststehenden Bauteil angeordnete Tasche zur Aufnahme des Formschlusselementes haben. Durch diese Gestaltung kann das Formschlusselement nach dem vorgesehenen Winkelbereich in die Tasche abtauchen und den Formschluss zwischen Kern und Schließbart lösen.To simplify the solution of the positive connection according to the intended angular range, it contributes according to another advantageous embodiment of the invention, when the means have a arranged in a fixed component pocket for receiving the positive locking element. By this design, the positive locking element can dive into the pocket after the intended angular range and solve the positive connection between the core and cam.
Die Erzeugung des Formschlusses zwischen Schließbart und Kern gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das der Führung gegenüberstehende Bauteil des Schließbartes oder des Kerns zumindest einen in den Bewegungsbereich des aus der Führung hervorstehenden Formschlusselementes hineinragenden Steuernocken hat.The generation of the positive connection between cam and core designed in accordance with another advantageous embodiment of the invention structurally particularly simple when the guide member opposite the cam or the core at least has a in the range of movement of the protruding from the guide positive engagement element control cam.
Der Freilauf des Schließbartes lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung im Grundzustand der Schließeinrichtung einfach sicherstellen, wenn in einer Schlüsselabzugsstellung des Sperrmechanismus das Formschlusselement außerhalb des Bewegungsbereichs des Steuernockens angeordnet ist. Durch diese Gestaltung ist der Formschluss im Grundzustand der Schließeinrichtung für einen Antrieb am Schließbart dauerhaft gelöst, so dass eine Blockierung eines Schlosses durch die im Grundzustand befindliche Schließeinrichtung vermieden ist.The freewheel of the cam can be easily ensured in accordance with another advantageous embodiment of the invention in the basic state of the locking device when the interlocking element is arranged outside the range of movement of the control cam in a key withdrawal position of the locking mechanism. By this design, the positive connection in the basic state of the closing device for a drive on the cam is permanently released, so that a blockage of a lock is avoided by the locking device located in the ground state.
Die Erzeugung des Freilaufes für den vorgesehenen Winkelbereich gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das der Führung gegenüberstehende Bauteil des Schließbartes oder des Kerns eine sich über den vorgesehenen Winkelbereich erstreckende, von dem Steuernocken begrenzte Nut zur Aufnahme des aus der Führung hervorstehenden Formschlusselementes hat. Durch diese Gestaltung ist in der einen Drehrichtung der Formschluss erzeugt, solange das Formschlusselement aus der Führung hervorsteht, jedoch in der entgegen gesetzten Drehrichtung der Formschluss über den vorgesehenen Winkelbereich gelöst, weil sich das Formschlusselement in der Nut bewegt.The generation of the freewheel for the intended angular range designed in accordance with another advantageous embodiment of the invention structurally particularly simple if the leadership of the opposing component of the cam or the core extending over the intended angular range, limited by the control cam groove for receiving the from Guide protruding positive locking element has. By this design, the positive connection is produced in one direction of rotation, as long as the positive locking element protrudes from the guide, but solved in the opposite direction of rotation of the positive locking over the intended angular range, because the positive locking element moves in the groove.
Ein Abwechseln des Formschlusses und des Freilaufes über mehrere Umdrehungen des Kerns lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erzeugen, wenn zwischen zwei Steuernocken eine Zweitnut zur Aufnahme des Formschlusselementes angeordnet ist und dass sich die Zweitnut zumindest über den Winkelbereich der Tasche in dem feststehenden Bauteil erstreckt. Hierdurch lässt sich gewährleisten, dass nach jeder vollständigen Umdrehung oder jeder zweiten vollständigen Umdrehung des Kerns ein Freilauf über eine Umdrehung des Kerns erzeugt ist. Die Wirkungsweise gilt zudem in beide Drehrichtungen.A change of the positive connection and the freewheel over several revolutions of the core can be easily generated according to another advantageous embodiment of the invention, if between two control cam a second groove for receiving the positive locking element is arranged and that the second groove at least over the angular range of the pocket in the fixed Component extends. This ensures that one freewheel is generated over one revolution of the core after every complete revolution or every second complete revolution of the core. The mode of action also applies in both directions.
Die Schließeinrichtung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kostengünstig fertigen, wenn das Formschlusselement als Kugel ausgebildet ist.According to another advantageous development of the invention, the closing device can be produced particularly inexpensively if the positive-locking element is designed as a ball.
Die Steuerung des Formschlusselementes in radialer Richtung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn zumindest eines der Bauteile der Tasche, der Nut und der Zweitnut an ihren Enden Rampen zur Bewegung des Formschlusselementes in die Führung aufweisen.The control of the positive locking element in the radial direction is particularly simple according to another advantageous embodiment of the invention, if at least one the components of the pocket, the groove and the second groove have at their ends ramps for moving the positive locking element in the guide.
Die Schließeinrichtung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn ein mit dem Kern verbundenes Ringelement die Führung, ein mit dem Schließbart verbundene Schließbarthülse den Steuernocken und/oder ein mit dem Gehäuse verbundener Gehäuseausleger die Tasche aufweist.According to another advantageous development of the invention, the closing device is structurally particularly simple if a ring element connected to the core has the guide, a cam bit connected to the cam has the control cam and / or a housing arm connected to the housing has the pocket.
