  • This locking device also known under the trade name TrioVing Trygg, can be mounted in front of the lock cylinder of a lock If a key is inserted into the lock channel of the lock cylinder, it can be locked in the lock channel of the lock cylinder by a locking element of the locking device If the key is not in key withdrawal position, the key can not be pulled out, but if the key is in the key withdrawal position, the locking device prevents the key from being pulled out of the lock cylinder, for example a key can be used as a rotary knob For example, without the key being accidentally removed from the lock cylinder, however, if it is desired to pull the key out of the lock cylinder in the key withdrawal position, it is e manual operation of the blocking element required, to solve the locking of the locking element with the key.
  • the blocking element is guided in the locking device in a lifting axis which extends radially to the preferably cylindrical locking cylinder.
  • the locking element is perpendicular to the lock cylinder axis back and forth movable.
  • the locking element In order to release the key from the locking by the locking element, the locking element has to be moved cumbersome in the lifting axis of the lock cylinder axis away.

  • the invention is based on the idea of creating a slide element which is accommodated in an advantageous and in particular ergonomic manner in the locking device, wherein initially the slide element cooperates with the locking element to release the locking of the key is enabled.
  • the slider element thus serves as a transfer means between the hand and in particular between a finger of an operator and the blocking element, so that the slider element serves as a control element.
  • the transversely provided mobility of the slide element thus means a possible direction of movement, which is perpendicular to the extension direction of the lock cylinder axis.
  • This direction of movement of the slide element thus extends in the plane of the door leaf, in which the lock cylinder is installed in particular as part of a lock. Due to the spacing from the lock cylinder axis, an operating height of the slide element relative to the lock cylinder axis arises, in which a simple interaction between a finger, a hand and the slider element can be done.
  • the pressure actuation by the finger can thus take place in the tangential direction to the lock cylinder, the tangential direction not being understood basically as a tangent on the outer circumference of the lock cylinder.
  • the rather tangential direction describes a direction transverse to the lock cylinder axis direction, which, however, can also be understood as a secant orĂȘte to the mathematical envelope shape of the lock cylinder.

Description

Die vorliegende Erfindung betrifft eine Arretiervorrichtung zur Arretierung eines SchlĂŒssels an einem Schließzylinder, wobei die Arretiervorrichtung zur stirnseitigen Anordnung am Schließzylinder ausgebildet ist und um eine Schließzylinderachse herum erstreckbar ist, wobei ein Sperrelement vorgesehen ist, das zur Arretierung des SchlĂŒssels in SchlĂŒsselabzugsstellung mit dem SchlĂŒssel verrastbar ist, wobei die Arretiervorrichtung ein quer und beabstandet zur Schließzylinderachse bewegbares Schieberelement aufweist, das durch manuelle DruckbetĂ€tigung in tangentialer Richtung zum Schließzylinder mit dem Sperrelement derart zusammenwirkt, dass ein Lösen der Verrastung des SchlĂŒssels ermöglicht ist, wobei das Schieberelement entlang einer Schieberachse bedinbar und bewegbar ist. Eine gattungsbildende Arretiervorrichtung zur Arretierung eines SchlĂŒssels an einem Einsteckschloss ist aus WO 03/071059 A1 bekannt.The present invention relates to a locking device for locking a key on a lock cylinder, wherein the locking device is formed to the frontal arrangement on the lock cylinder and is extendable about a lock cylinder axis, wherein a locking element is provided, which can be locked to lock the key in key withdrawal position with the key wherein the locking device comprises a transversely and spaced from the lock cylinder axis movable slide element which cooperates by manual pressure operation in the tangential direction to the lock cylinder with the locking element such that a release of the latching of the key is enabled, wherein the slide element along a slide axis is bedinbar and movable. A generic locking device for locking a key on a mortise lock is off WO 03/071059 A1 known.

Eine andere Arretiervorrichtung zur Arretierung eines SchlĂŒssels an einem Schließzylinder ist vom Hersteller TrioVing/ASSA ABLOY, www.trioving.no bekannt, siehe Produktkatalog 2008, Seite 53, Produktbezeichnung "Knappsperre for 5596C ". Diese ferner unter der Handelsbezeichnung TrioVing Trygg bekannte Arretiervorrichtung kann stirnseitig vor den Schließzylinder eines Schlosses montiert werden. Wird ein SchlĂŒssel in den Schließkanal des Schließzylinders eingefĂŒhrt, so kann dieser durch ein Sperrelement der Arretiervorrichtung im Schließkanal des Schließzylinders arretiert werden. Befindet sich der SchlĂŒssel nicht in SchlĂŒsselabzugsstellung, so kann der SchlĂŒssel aus dem Schließzylinder grundsĂ€tzlich nicht herausgezogen werden. Befindet sich jedoch der SchlĂŒssel in SchlĂŒsselabzugsstellung, so verhindert die Arretiervorrichtung durch das Sperrelement, dass der SchlĂŒssel aus dem Schließzylinder herausgezogen werden kann. Folglich kann beispielsweise ein SchlĂŒssel als Drehknauf verwendet werden, ohne dass der SchlĂŒssel beispielsweise versehentlich vom Schließzylinder abgezogen wird. Ist es jedoch gewĂŒnscht, den SchlĂŒssel in SchlĂŒsselabzugsstellung aus dem Schließzylinder herauszuziehen, so ist eine manuelle BetĂ€tigung des Sperrelementes erforderlich, um die Verrastung des Sperrelementes mit dem SchlĂŒssel zu lösen.Another locking device for locking a key to a lock cylinder is from Manufacturer TrioVing / ASSA ABLOY, www.trioving.no known, see product catalog 2008, page 53, product description "Knappsperre for 5596C This locking device, also known under the trade name TrioVing Trygg, can be mounted in front of the lock cylinder of a lock If a key is inserted into the lock channel of the lock cylinder, it can be locked in the lock channel of the lock cylinder by a locking element of the locking device If the key is not in key withdrawal position, the key can not be pulled out, but if the key is in the key withdrawal position, the locking device prevents the key from being pulled out of the lock cylinder, for example a key can be used as a rotary knob For example, without the key being accidentally removed from the lock cylinder, however, if it is desired to pull the key out of the lock cylinder in the key withdrawal position, it is e manual operation of the blocking element required, to solve the locking of the locking element with the key.

Das Sperrelement ist in der Arretiervorrichtung in einer Hubachse gefĂŒhrt, die radial zum vorzugsweise zylindrisch ausgefĂŒhrten Schließzylinder verlĂ€uft. Damit ist das Sperrelement senkrecht zur Schließzylinderachse hin- und her bewegbar. Um den SchlĂŒssel aus der Verrastung durch das Sperrelement freizugeben, muss das Sperrelement umstĂ€ndlich in der Hubachse von der Schließzylinderachse weg bewegt werden. Das Lösen des SchlĂŒssels aus der Verrastung ist folglich nur mit zwei HĂ€nden möglich, in dem mit einer Hand der SchlĂŒssel gegriffen und aus dem Schließzylinder herausgezogen wird, wĂ€hrend mit der anderen Hand das Sperrelement ĂŒber eine außenseitig angeformte Bedienlasche gegen eine Federkraft von der Schließzylinderachse wegbewegt werden muss. Will ein Bediener mit nur einer Hand den SchlĂŒssel aus der Schließzylinderachse herausziehen, wĂ€hrend zugleich von Hand das Sperrelement gegen die Federkraft in Freihaltestellung gehalten werden muss, so kann - wenn ĂŒberhaupt - das Sperrelement lediglich mit dem Daumen von der Schließzylinderachse weg bewegt werden. Damit ergibt sich eine nachteilhafte Bedienung der Arretiervorrichtung, und es ist wĂŒnschenswert, eine Vereinfachung der Bedienung der Arretiervorrichtung insbesondere zur Freigabe des SchlĂŒssels zu schaffen.The blocking element is guided in the locking device in a lifting axis which extends radially to the preferably cylindrical locking cylinder. Thus, the locking element is perpendicular to the lock cylinder axis back and forth movable. In order to release the key from the locking by the locking element, the locking element has to be moved cumbersome in the lifting axis of the lock cylinder axis away. The release of the key from the latch is therefore possible only with two hands in which one hand gripped the key and pulled out of the lock cylinder, while the other hand, the locking element are moved away via an externally molded control tab against a spring force from the lock cylinder axis got to. If an operator wants to extract the key from the lock cylinder axis with only one hand, while at the same time the locking element must be kept in the free-hold position against the spring force by hand, then the locking element can be moved away from the lock cylinder axis, if at all, with only the thumb. This results in a disadvantageous operation of the locking device, and it is desirable to provide a simplification of the operation of the locking device in particular to release the key.

Es ist die Aufgabe der vorliegenden Erfindung, eine Arretiervorrichtung zur Arretierung eines SchlĂŒssels an einem Schließzylinder zu schaffen, die eine verbesserte Bedienung ermöglicht. Insbesondere ist es die Aufgabe der vorliegenden Erfindung, eine Arretiervorrichtung zu schaffen, bei der die Verrastung des SchlĂŒssels und die gleichzeitige Entnahme des SchlĂŒssels aus dem Schließzylinder mit nur einer Hand erfolgen kann.It is the object of the present invention to provide a locking device for locking a key on a lock cylinder, which enables improved operation. In particular, it is the object of the present invention to provide a locking device in which the locking of the key and the simultaneous removal of the key from the lock cylinder can be done with one hand.

Diese Aufgabe wird ausgehend von einer Arretiervorrichtung zur Arretierung eines Schlosses an einem Schließzylinder gemĂ€ĂŸ dem Oberbegriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhĂ€ngigen AnsprĂŒchen angegeben.This object is based on a locking device for locking a lock on a lock cylinder according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die technische Lehre ein, dass die Wirkverbindung zwischen dem Schieberelement und dem Sperrelement derart ausgebildet ist, dass ein Lösen der Verrastung des SchlĂŒssels durch ein Bewegen des Schieberelementes in beiden Richtungen der Schieberachse ermöglicht ist. Das hat zur Folge, dass in AbhĂ€ngigkeit von baulichen Gegebenheiten, z. B. durch eine angrenzende, rechtwinklig zur TĂŒr verlaufende Wand, das Schieberelement sowohl von links als auch von rechts bedient werden kann, um den SchlĂŒssel zu entrasten. Insbesondere kann sowohl mit der rechten Hand als auch mit der linken Hand der SchlĂŒssel aus dem Schließzylinder entnommen werden, so dass entweder beispielsweise die Bedienung des Schieberelementes mit der rechten Hand von der linken Seite erfolgt, und mit der linken Hand von der rechten Seite, da die jeweilige Daumenseite die Bedienseite bildet.The invention includes the technical teaching that the operative connection between the slider element and the locking element is designed such that a release of the locking of the key is made possible by moving the slider element in both directions of the slide axis. This has the consequence that, depending on structural conditions, eg. B. by an adjacent, perpendicular to the door wall, the slider element can be operated both from the left and from the right to unlatch the key. In particular, both with the right hand and with the left hand, the key can be removed from the lock cylinder, so that either, for example, the operation of the slider element with the right hand from the left side, and with the left hand from the right side, there the respective thumb side forms the operating side.

Die Erfindung geht dabei von dem Gedanken aus, ein Schieberelement zu schaffen, das auf vorteilhafte und insbesondere ergonomische Weise in der Arretiervorrichtung aufgenommen wird, wobei zunĂ€chst das Schieberelement mit dem Sperrelement zusammenwirkt, um ein Lösen der Verrastung des SchlĂŒssels ermöglicht ist. Das Schieberelement dient folglich als Übertragungsmittel zwischen der Hand und insbesondere zwischen einem Finger eines Bedieners und dem Sperrelement, so dass das Schieberelement als Bedienelement dient. Durch eine Bewegungsmöglichkeit des Schieberelementes quer und beabstandet zur Schließzylinderachse wird erreicht, dass eine ergonomische Bedienbarkeit der Arretiervorrichtung entsteht. Die quer vorgesehene Bewegbarkeit des Schieberelementes meint damit eine mögliche Bewegungsrichtung, die senkrecht zur Erstreckungsrichtung der Schließzylinderachse verlĂ€uft. Diese Bewegungsrichtung des Schieberelementes verlĂ€uft folglich in der Ebene des TĂŒrblattes, in dem der Schließzylinder insbesondere als Bestandteil eines Schlosses eingebaut ist. Durch die Beabstandung zur Schließzylinderachse entsteht eine Bedienhöhe des Schieberelementes relativ zur Schließzylinderachse, in der auf einfache Weise eine Wechselwirkung zwischen einem Finger, einer Hand und dem Schieberelement erfolgen kann. Die DruckbetĂ€tigung durch den Finger kann folglich in tangentialer Richtung zum Schließzylinder erfolgen, wobei die tangentiale Richtung nicht grundsĂ€tzlich als Tangente auf dem Ă€ußeren Umfang des Schließzylinders zu verstehen ist. Die tangentiale Richtung beschreibt vielmehr eine quer zur Schließzylinderachse verlaufende Richtung, die jedoch auch als Sekante oder als Passante zur mathematischen HĂŒllform des Schließzylinders verstanden werden kann.The invention is based on the idea of creating a slide element which is accommodated in an advantageous and in particular ergonomic manner in the locking device, wherein initially the slide element cooperates with the locking element to release the locking of the key is enabled. The slider element thus serves as a transfer means between the hand and in particular between a finger of an operator and the blocking element, so that the slider element serves as a control element. By a possibility of movement of the slider element transversely and spaced from the lock cylinder axis is achieved that an ergonomic operation of the locking device is formed. The transversely provided mobility of the slide element thus means a possible direction of movement, which is perpendicular to the extension direction of the lock cylinder axis. This direction of movement of the slide element thus extends in the plane of the door leaf, in which the lock cylinder is installed in particular as part of a lock. Due to the spacing from the lock cylinder axis, an operating height of the slide element relative to the lock cylinder axis arises, in which a simple interaction between a finger, a hand and the slider element can be done. The pressure actuation by the finger can thus take place in the tangential direction to the lock cylinder, the tangential direction not being understood basically as a tangent on the outer circumference of the lock cylinder. The rather tangential direction describes a direction transverse to the lock cylinder axis direction, which, however, can also be understood as a secant or passante to the mathematical envelope shape of the lock cylinder.

Vorzugsweise ist die Anordnung des Schieberelementes derart quer und beabstandet zur Schließzylinderachse ausgefĂŒhrt, dass die manuelle DruckbetĂ€tigung auf das Schieberelement durch einen Finger, vorzugsweise durch einen Daumen ausfĂŒhrbar ist, insbesondere wenn der SchlĂŒssel zugleich manuell gehalten ist. Beispielsweise kann der SchlĂŒsselkörper ĂŒber die SchlĂŒsselreide von der Vorderhand, das dem ersten bis vierten Finger, gehalten werden, wĂ€hrend das Schieberelement mit dem Daumen bedient wird. Dadurch entsteht eine ergonomische Handbewegung zur Entnahme des SchlĂŒssels aus dem Schließzylinder. Der Schließzylinder ist vorliegend als Einbauteil in ein Schloss fĂŒr eine TĂŒr, ein Fenster, ein Tor oder dergleichen zu verstehen, wobei der Schließzylinder einen Schließzylinderkern aufweist, in den der SchlĂŒssel einfĂŒhrbar ist, und der mit dem SchlĂŒssel im Schließzylinder rotierbar ist. Die Arretiervorrichtung ist gemĂ€ĂŸ der vorliegenden Erfindung stirnseitig an den Schließzylinder anordbar, so dass die Arretiervorrichtung vor dem Schließzylinder in zugĂ€nglicher Weise des TĂŒrblattes montiert ist.Preferably, the arrangement of the slider element is designed transversely and spaced from the lock cylinder axis, that the manual pressure actuation on the slider element by a finger, preferably by a thumb is executable, especially if the key is also held manually. For example, the key body can be held by the forehead, the first to the fourth fingers, over the crayons while the pusher member is operated with the thumb. This creates an ergonomic hand movement for removal of the key from the lock cylinder. The lock cylinder is presently understood as a built-in part in a lock for a door, a window, a gate or the like, wherein the lock cylinder has a lock cylinder core into which the key is inserted, and which is rotatable with the key in the lock cylinder. The locking device can be arranged according to the present invention, the front side of the lock cylinder, so that the locking device is mounted in front of the lock cylinder in an accessible manner of the door leaf.

Nach einer bevorzugten AusfĂŒhrungsform der Arretiervorrichtung ist ein etwa scheibenförmiger Grundkörper vorgesehen, in dem vorzugsweise ein Schieberkanal zur FĂŒhrung des Schieberelementes ausgebildet ist, der quer und beabstandet zur Schließzylinderachse etwa tangential zum Schließzylinder durch den Grundkörper verlĂ€uft. Der Grundkörper kann als metallisches Bauteil durch spanende Verfahren oder durch Gussverfahren, beispielsweise durch ein Druckgussverfahren oder ein MINM- Verfahren, hergestellt werden. Ferner kann der Grundkörper aus einem Kunststoffmaterial gebildet sein, wobei sĂ€mtliche Funktionsgeometrien und FunktionsflĂ€chen vorzugsweise direkt am einteiligen Grundkörper angebracht sind. Die scheibenförmige Grundstruktur beschreibt einen flachen Zylinder, der im Durchmesser vorzugsweise an den Durchmesser des Schließzylinders angepasst ist. Um das Schieberelement vorteilhaft im Grundkörper aufzunehmen, ist ein Schieberkanal vorgesehen, der insbesondere als eine Vertiefung zu einer PlanflĂ€che des scheibenförmigen Grundkörpers hin ausgebildet sein kann. Die PlanflĂ€che, zu der der Schieberkanal offen ausgestaltet ist, bildet im montierten Zustand die KontaktflĂ€che des Grundkörpers an der Stirnseite des Schließzylinders. Damit ergibt sich eine einfache Montierbarkeit des Schieberelementes, welches im montierten Zustand des Grundkörpers an der Stirnseite des Schließzylinders ferner gegen die Stirnseite des Schließzylinders gefĂŒhrt ist. Die tangentiale Ausrichtung des Schieberkanals zum Schließzylinder gibt folglich die Bewegungsrichtung und damit die Bedienrichtung des Schieberelementes vor.According to a preferred embodiment of the locking device, an approximately disc-shaped base body is provided, in which preferably a slide channel is designed for guiding the slide element, which extends transversely and spaced from the lock cylinder axis approximately tangential to the lock cylinder through the main body. The base body can be produced as a metallic component by machining processes or by casting processes, for example by a die casting process or a MINM process. Furthermore, the main body may be formed of a plastic material, wherein all functional geometries and functional surfaces are preferably mounted directly on the one-piece base body. The disc-shaped basic structure describes a flat cylinder, which is preferably adapted in diameter to the diameter of the lock cylinder. In order to advantageously receive the slide element in the main body, a slide channel is provided, which can be designed in particular as a depression to a plane surface of the disc-shaped base body. The planar surface, to which the slide channel is designed to be open, forms the contact surface of the base body on the end face of the lock cylinder in the mounted state. This results in a simple mountability of the slide element, which is further guided in the mounted state of the body on the front side of the lock cylinder against the end face of the lock cylinder. The tangential orientation of the slide channel to the lock cylinder thus gives the direction of movement and thus the operating direction of the slide element.

Das Sperrelement kann in einer Hubachse hubbeweglich im Grundkörper aufgenommen sein, wobei das Sperrelement zur Verrastung mit dem SchlĂŒssel in einen SchlĂŒsseldurchgang hineinragt und aus diesem zurĂŒckziehbar ist, der im Grundkörper eingebracht ist. Dabei kann der SchlĂŒssel eine Rastnase aufweisen, in die das Sperrelement zur Verrastung des SchlĂŒssels am Schließzylinder dann einrastet, wenn das Sperrelement in den SchlĂŒsseldurchgang hineinragt, wobei die Hubachse vorzugsweise radial zum Schließzylinder verlĂ€uft. Durch den Verlauf der Hubachse ist die Bewegungsrichtung des Sperrelementes zur Bewegungsrichtung des Schieberelementes senkrecht im Grundkörper der Arretiervorrichtung angeordnet. Ebenso wie die Anordnung des Schieberelementes im Schieberkanal kann das Sperrelement in einem Hubkanal angeordnet sein, wobei der Hubkanal senkrecht zum Schieberkanal verlĂ€uft und mit dem Schieberkanal einen Kreuzungspunkt aufweist. Das Sperrelement wird derart in den Hubkanal eingebracht, dass dieses in der Stellung zur Verrastung des SchlĂŒssels am Schließzylinder in den SchlĂŒsseldurchgang hineinragt. Die Rastnase am SchlĂŒssel ist so ausgefĂŒhrt, dass bei Verrastung des Sperrelementes an der Rastnase der SchlĂŒssel nicht aus dem Schließzylinder entnommen werden kann. Wird das Schieberelement im Schieberkanal bewegt, so bewegt sich das Sperrelement durch die Wirkverbindung zwischen dem Sperrelement und dem Schieberelement aus dem SchlĂŒsseldurchgang heraus, so dass der SchlĂŒssel auch mit der Rastnase frei durch den SchlĂŒsseldurchgang bewegbar ist.The blocking element can be received in a liftable lifting in the base body, wherein the locking element for locking with the Key protrudes into a keyway and is retractable from this, which is introduced in the body. In this case, the key may have a detent into which the locking element for locking the key on the lock cylinder then locks when the locking element projects into the keyway, wherein the lifting axis preferably extends radially to the lock cylinder. Due to the course of the lifting axis, the direction of movement of the blocking element is arranged perpendicular to the direction of movement of the slide element in the main body of the locking device. As well as the arrangement of the slide element in the slide channel, the blocking element can be arranged in a Hubkanal, wherein the Hubkanal perpendicular to the slide channel and with the slide channel has a crossing point. The blocking element is introduced into the lifting channel in such a way that it projects into the keyed passage in the position for locking the key on the locking cylinder. The latch on the key is designed so that when locking the locking element on the locking lug the key can not be removed from the lock cylinder. If the slide element is moved in the slide channel, then the blocking element moves out of the keyed passage through the operative connection between the blocking element and the slide element, so that the key can also be moved freely with the latching lug through the key passage.

GemĂ€ĂŸ einer bevorzugten AusfĂŒhrungsform einer Wirkverbindung zwischen dem Schieberelement und dem Sperrelement weist das Schieberelement eine WirkflĂ€che mit einer Rastkerbe auf, wobei das Sperrelement einen Druckzapfen aufweist. Die Wirkverbindung zwischen dem Schieberelement und dem Sperrelement wird durch ein Abgleiten des Druckzapfens ĂŒber der Rastkerbe gebildet ist. Durch die manuelle BetĂ€tigung des Schieberelementes wird dieses senkrecht zum Sperrelement bewegt. Folglich gleitet die Rastkerbe des Schieberelementes unter dem Druckzapfen des Sperrelementes hinweg. Die Rastkerbe bildet die Mittelstellung des Schieberelementes, so dass der Druckzapfen in die Rastkerbe einrasten kann, wenn das Schieberelement nicht betĂ€tigt ist und sich in Mittelstellung befindet. Rastet der Druckzapfen in die Rastkerbe ein, ist der Weg des Sperrelementes entlang des Hubkanals freigegeben, und das Sperrelement kann teilweise in den SchlĂŒsseldurchgang hineinragen, um mit der Rastnase am SchlĂŒssel in Wirkverbindung zu treten.According to a preferred embodiment of an operative connection between the slide element and the blocking element, the slide element has an active surface with a latching notch, wherein the blocking element has a pressure pin. The operative connection between the slide element and the blocking element is formed by a sliding of the pressure pin on the notch. By the manual operation of the slider element this is moved perpendicular to the blocking element. Consequently, the notch of the slider element slides under the pressure pin of the locking element away. The latching notch forms the middle position of the slide element, so that the pressure pin engage in the latching notch can when the slider element is not actuated and is in the center position. If the pressure pin engages in the latching notch, the path of the blocking element along the lifting channel is released, and the blocking element can partially protrude into the keyway in order to come into operative connection with the latching lug on the key.

Um ein Abgleiten des Druckzapfens ĂŒber der Rastkerbe sicherzustellen, ist ein Federelement vorgesehen, welches das Sperrelement in Richtung zur Verrastung des Sperrelementes in die Rastnase des SchlĂŒssels vorspannt. Durch die Vorspannung des Federelementes erfolgt ein permanentes Abgleiten des Druckzapfens ĂŒber der Rastkerbe. Die WirkflĂ€che ist links und rechts der Rastkerbe ausgebildet, so dass bei Abgleiten des Druckzapfens in Richtung der WirkflĂ€che das Sperrelement aus dem SchlĂŒsseldurchgang herausgefĂŒhrt ist. Befindet sich das Schieberelement in Mittelstellung, so ist die Rastkerbe unmittelbar unterhalb des Druckzapfens angeordnet. In dieser Stellung ist ein Weg des Sperrelementes in Richtung zum SchlĂŒsseldurchgang freigegeben, da der Druckzapfen in die Rastkerbe einrasten kann, die eine Vertiefung in der WirkflĂ€che des Schieberelementes darstellt.In order to ensure slipping of the pressure pin on the notch, a spring element is provided which biases the locking element in the direction of locking the locking element in the locking lug of the key. By the bias of the spring element is a permanent sliding of the pressure pin on the notch. The active surface is formed on the left and right of the latching notch, so that when the pressure pin slides in the direction of the effective surface, the blocking element is led out of the keyed passage. The slider element is in the middle position, the notch is located immediately below the pressure pin. In this position, a path of the locking element is released in the direction of the keyway, since the pressure pin can engage in the notch, which represents a depression in the effective surface of the slide element.

Wird das Schieberelement durch manuelles BetĂ€tigen entlang der Schieberachse bewegt, so wandert der Druckzapfen wieder aus der Rastkerbe heraus, und das Sperrelement wird entgegen der Richtung zur Schließzylinderachse in der Hubachse bewegt. Damit wird der sperrende Teil des Sperrelementes aus dem SchlĂŒsseldurchgang wieder herausgefĂŒhrt, und eine Entnahme des SchlĂŒssels aus dem Schließzylinder ist freigegeben. Durch die symmetrische Anordnung des Schieberelementes kann der Druckzapfen in beiden Richtungen aus der Rastkerbe herausgefĂŒhrt werden, so dass unabhĂ€ngig von der Bewegungsrichtung des Schieberelementes in der Schieberachse eine Hubbewegung des Sperrelementes von der Schließzylinderachse weg erfolgt.If the slide element is moved by manual actuation along the slide axis, then the pressure pin moves out of the latching notch again, and the blocking element is moved counter to the direction of the lock cylinder axis in the stroke axis. Thus, the blocking part of the blocking element is led out of the keyway again, and a removal of the key from the lock cylinder is released. Due to the symmetrical arrangement of the slide element, the pressure pin can be led out of the notch in both directions, so that regardless of the direction of movement of the slide element in the slide axis, a lifting movement of the locking element takes place away from the lock cylinder axis.

Vorzugsweise ist ein FĂŒhrungselement vorgesehen, das zur FĂŒhrung und vorzugsweise zur Bewegungsbegrenzung des Sperrelementes und des Schieberelementes ausgebildet und insbesondere im Grundkörper eingebracht ist. Das FĂŒhrungselement kann einen Zylinderstift bilden, der fest im Grundkörper eingesetzt ist. Sowohl im Schieberelement als auch im Sperrelement ist ein Langloch eingebracht, durch das sich das FĂŒhrungselement jeweils hindurch erstreckt. Das FĂŒhrungselement bildet folglich den Kreuzungspunkt zwischen den Bewegungsachsen des Schieberelementes und des Sperrelementes, die senkrecht zueinander verlaufen.Preferably, a guide element is provided, which is designed for guiding and preferably for limiting the movement of the locking element and the slider element and in particular in the base body is introduced. The guide element may form a cylindrical pin which is firmly inserted in the base body. Both in the slider element and in the blocking element, a slot is introduced, through which the guide element extends through each. The guide element thus forms the point of intersection between the axes of movement of the slider element and the blocking element, which run perpendicular to each other.

Nach einer weiteren vorteilhaften AusfĂŒhrungsform weist das Schieberelement zwei Drucktaster auf, die derart endseitig am Schieberelement angeformt sind, dass mit manuellem Druck auf die Drucktaster das Schieberelement in der Schieberachse bewegbar ist, wobei die Drucktaster vorzugsweise in die UmfangsflĂ€che des scheibenförmigen Grundkörpers integriert sind. Das Schieberelement kann einen etwa rechteckförmigen Querschnitt senkrecht zur Schieberachse aufweisen, wobei die Drucktaster in GrĂ¶ĂŸe und Form derart ausgebildet sind, dass diese sich in die UmfangsflĂ€che des scheibenförmigen Grundkörpers integrieren. Dabei können die Drucktaster derart ausgefĂŒhrt sein, dass diese nicht ĂŒber die Grundabmessungen des Grundkörpers hinausragen, insbesondere ragen die Drucktaster nicht ĂŒber eine der PlanflĂ€chen des Grundkörpers hinaus, wodurch die Bruchgefahr der Drucktaster minimiert wird.According to a further advantageous embodiment, the slide element on two push-buttons, which are integrally formed on the end of the slide element, that with manual pressure on the push button, the slide element in the slide axis is movable, wherein the push buttons are preferably integrated into the peripheral surface of the disc-shaped base body. The slide element may have an approximately rectangular cross section perpendicular to the slide axis, wherein the push buttons are formed in size and shape such that they integrate into the peripheral surface of the disc-shaped base body. In this case, the push-buttons can be designed such that they do not protrude beyond the basic dimensions of the base body, in particular the push-buttons do not project beyond one of the plane surfaces of the base body, whereby the risk of breakage of the push-button is minimized.

Der Grundkörper kann zur stirnseitigen Anordnung am Schließzylinder ausgefĂŒhrt sein, wobei der Grundkörper wenigstens ein Durchgangsloch aufweist, durch das ein Schraubelement zur Verschraubung des Grundkörpers an der Stirnseite des Schließzylinders hindurch fĂŒhrbar ist. Vorzugsweise können zwei Durchgangslöcher benachbart zum SchlĂŒsseldurchgang vorgesehen sein, so dass eine Verschraubung des Grundkörpers am Schließzylinder ermöglicht wird.The main body can be designed for frontal arrangement on the lock cylinder, wherein the base body has at least one through hole through which a screw for screwing the body on the front side of the lock cylinder can be guided. Preferably, two through holes may be provided adjacent to the keyway, so that a screwing of the base body is made possible on the lock cylinder.

Nach einer weiteren vorteilhaften AusfĂŒhrungsform der erfindungsgemĂ€ĂŸen Arretiervorrichtung kann ein elektrisches Erkennungsmittel vorgesehen sein, durch das wenigstens die Verrastung des SchlĂŒssels am Schließzylinder erkennbar ist. Das elektrische Erkennungsmittel kann einen Mikroschalter umfassen, welcher die verrastete Anordnung des SchlĂŒssels in der Arretiervorrichtung sensiert. Damit kann ein elektrisches Signal bereitgestellt werden, um beispielsweise zu erfassen, ob der Schließzylinder eine Drehknauffunktion durch den SchlĂŒssel bietet oder ob der SchlĂŒssel abgezogen ist oder zum Abziehen freigegeben ist.According to a further advantageous embodiment of the locking device according to the invention, an electrical detection means may be provided, by which at least the locking of the key on the lock cylinder can be seen. The electrical detection means may comprise a microswitch which senses the latched arrangement of the key in the locking device. Thus, an electrical signal can be provided to detect, for example, whether the lock cylinder provides a rotary knob function by the key or whether the key is removed or released for removal.

Ferner kann ein weiteres oder alternatives elektrisches Erkennungsmittel vorgesehen sein, das die Anordnung einer Arretiervorrichtung an einem Schließzylinder eines Schlosses sensiert. Dieses elektrische Erkennungsmittel kann in der Arretiervorrichtung oder im Schloss integriert sein.Furthermore, a further or alternative electrical detection means can be provided which senses the arrangement of a locking device on a lock cylinder of a lock. This electrical detection means may be integrated in the locking device or in the lock.

Die Aufgabe der vorliegenden Erfindung wird ferner gelöst durch ein Schloss mit einer Arretiervorrichtung nach Anspuch 1 zur Arretierung eines SchlĂŒssels an einem Schließzylinder des Schlosses.The object of the present invention is further achieved by a lock with a locking device according Anspuch 1 for locking a key to a lock cylinder of the castle.

Die Figur 1 zeigt ein AusfĂŒhrungsbeispiel einer erfindungsgemĂ€ĂŸen Arretiervorrichtung 1, die stirnseitig an einem Schließzylinder 11 angeordnet ist. Die Darstellung zeigt zwei sich gegenĂŒberliegende Schließzylinder 11, die mit Schraubelementen 26 miteinander verschraubt sind. Zur Anordnung der Arretiervorrichtung 1 am vorderseitig dargestellten Schließzylinder 11 verlaufen zwei Schraubelemente 26 derart durch die Arretiervorrichtung 1, dass diese sowohl eine gegenseitige Verspannung der gezeigten Schließzylinder 11 als auch eine Befestigung der Arretiervorrichtung 1 am Schließzylinder 11 ermöglichen. Sind die Schließzylinder 11 beispielsweise seitlich an einem Schlosskasten angeordnet, das in einem TĂŒrblatt eingebaut ist, können die Schließzylinder 11 zur endgĂŒltigen Befestigung durch Spannmuttern 27 im TĂŒrblatt verspannt werden. Die Spannmuttern 27 sind dafĂŒr auf einem außenseitig auf den Schließzylindern 11 aufgebrachtes Gewinde aufschraubbar.The FIG. 1 shows an embodiment of a locking device 1 according to the invention, which is arranged on the front side of a lock cylinder 11. The illustration shows two opposite locking cylinder 11, which are screwed together with screw 26. For the arrangement of the locking device 1 on the lock cylinder 11 shown on the front side, two screw elements 26 extend through the locking device 1 in such a way that they both exhibit a mutual tension of the one shown Lock cylinder 11 and allow attachment of the locking device 1 on the lock cylinder 11. If the lock cylinder 11, for example, arranged laterally on a lock case, which is installed in a door leaf, the lock cylinder 11 can be braced for final attachment by clamping nuts 27 in the door leaf. The clamping nuts 27 can be screwed on a externally applied to the lock cylinders 11 thread.

Im vorderseitig dargestellten Schließzylinder 11 ist ein SchlĂŒssel 10 eingesteckt, der in einer Abzugsstellung gezeigt ist. Durch die Arretiervorrichtung 1 wird der SchlĂŒssel 10 am Schließzylinder 11 arretiert, so dass der SchlĂŒssel 10 auch in der SchlĂŒsselabzugsstellung nicht aus dem Schließzylinder 11 entnommen werden kann. Folglich kann der SchlĂŒssel 10 eine Knauffunktion erfĂŒllen, wobei die Arretiervorrichtung 1 vorzugsweise auf dem Schließzylinder 11 eines TĂŒrblattes angeordnet wird, der zu einer Rauminnenseite weist.In the lock cylinder 11 shown on the front side, a key 10 is inserted, which is shown in a deduction position. By the locking device 1, the key 10 is locked to the lock cylinder 11, so that the key 10 can not be removed from the lock cylinder 11 in the key withdrawal position. Consequently, the key 10 can perform a knob function, wherein the locking device 1 is preferably arranged on the lock cylinder 11 of a door leaf, which faces a room inside.

Die Darstellung zeigt die Arretiervorrichtung 1 mit einem erfindungsgemĂ€ĂŸen Schieberelement 13, welches manuell durch DruckbetĂ€tigung in tangentialer Richtung zum Schließzylinder 11 betĂ€tigt werden kann. Durch die BetĂ€tigung des Schieberelementes 13 kann der SchlĂŒssel 10 freigegeben werden, um diesen aus dem Schließzylinder 11 herauszuziehen. Das Schieberelement 13 erstreckt sich nach Art einer Sekante durch den Grundkörper 15 der Arretiervorrichtung 1, so dass das Schieberelement 13 die MantelflĂ€che des Grundkörpers 15 an zwei sich gegenĂŒberliegenden Seiten durchstĂ¶ĂŸt. An den Endseiten des Schieberelementes 13 kann durch manuelle DruckbetĂ€tigung eine Bewegung des Schieberelementes 13 erzeugt werden, so dass der SchlĂŒssel 10 zur Entnahme aus dem Schließzylinder 11 freigegeben wird.The illustration shows the locking device 1 with a slide element 13 according to the invention, which can be manually operated by pressure actuation in the tangential direction to the lock cylinder 11. By the operation of the slide element 13, the key 10 can be released to pull it out of the lock cylinder 11. The slider element 13 extends in the manner of a secant through the main body 15 of the locking device 1, so that the slider element 13 pierces the lateral surface of the base body 15 on two opposite sides. At the end sides of the slide element 13, a movement of the slide element 13 can be generated by manual pressure actuation, so that the key 10 is released for removal from the lock cylinder 11.

Figur 2 zeigt eine Vorderansicht der Anordnung der Arretiervorrichtung 1 am Schließzylinder 11. Der Durchmesser des scheibenförmigen Grundkörpers 15 der Arretiervorrichtung 1 ist dem Durchmesser des Schließzylinders 11 angepasst und erstreckt sich im Wesentlichen um die Schließzylinderachse 12, die die LĂ€ngsachse des Schließzylinderkerns bildet, in der der SchlĂŒssel 10 rotierbar ist. Die Bewegungsrichtung des Schieberelementes 13 ist durch einen Doppelpfeil angedeutet und verlĂ€uft in einer Schieberachse 14. Das Schieberelement 13 kann sowohl von der linken Seite als auch von der rechten Seite druckbetĂ€tigt werden, um das Schieberelement 13 in der Schieberachse 14 seitlich zu verlagern. GemĂ€ĂŸ der Darstellung ist erkennbar, dass die Anordnung des Schieberelementes 13 unter BerĂŒcksichtigung des Verlaufes der Schieberachse 14 einen ergonomischen Vorteil bietet, da der SchlĂŒssel 10 mit der Vorderhand umschlossen werden kann, wĂ€hrend das Schieberelement 13 zur Entnahme des SchlĂŒssels 10 mit dem Daumen betĂ€tigt wird. Durch die beiderseitige Bewegbarkeit des Schieberelementes 13 kann sowohl von der linken Seite mit dem Daumen der rechten Hand als auch von der rechten Seite mit dem Daumen der linken Hand eine BetĂ€tigung des Schieberelementes 13 auf ergonomische Weise erfolgen, wobei zugleich der SchlĂŒssel 10 mit der Vorderhand aus dem Schließzylinder 11 entnommen werden kann, wĂ€hrend das Schieberelement 13 betĂ€tigt ist. Die Wirkverbindung zwischen der Verrastung des SchlĂŒssels 10 und der BetĂ€tigung des Schieberelementes 13 ist in der folgenden Figur in einer Explosionsdarstellung der Arretiervorrichtung 1 nĂ€her gezeigt. FIG. 2 shows a front view of the arrangement of the locking device 1 on the lock cylinder 11. The diameter of the disc-shaped base body 15 of the locking device 1 is adapted to the diameter of the lock cylinder 11 and extends substantially around the lock cylinder axis 12, which forms the longitudinal axis of the lock cylinder core, in which the key 10 is rotatable. The direction of movement of the slide element 13 is indicated by a double arrow and extends in a slide axis 14. The slide element 13 can be pressure-actuated both from the left side and from the right side to laterally displace the slide element 13 in the slide axis 14. According to the illustration, it can be seen that the arrangement of the slide element 13, taking into account the progression of the slide axis 14, offers an ergonomic advantage, since the key 10 can be enclosed with the fore hand while the slide element 13 is actuated with the thumb to remove the key 10. Due to the mutual mobility of the slider element 13, an actuation of the slider element 13 can take place ergonomically from both the left side with the thumb of the right hand and from the right side with the thumb of the left hand, at the same time the key 10 with the fore hand the lock cylinder 11 can be removed while the slider element 13 is actuated. The operative connection between the locking of the key 10 and the actuation of the slide element 13 is shown in more detail in the following figure in an exploded view of the locking device 1.

Figur 3 zeigt in einer Explosionsdarstellung das AusfĂŒhrungsbeispiel der Arretiervorrichtung 1 gemĂ€ĂŸ der vorliegenden Erfindung. Die Arretiervorrichtung 1 umfasst zunĂ€chst einen Grundkörper 15, der als Einzelteil ausgefĂŒhrt ist und zur Aufnahme und FĂŒhrung weiterer die Arretiervorrichtung 1 bildender Bauteil entsprechende Aussparungen und KanĂ€le aufweist. Insbesondere weist der Grundkörper 15 einen SchlĂŒsseldurchgang 28 auf, durch den sich der SchlĂŒssel 10 im in den Schließzylinder 11 eingesteckten Zustand hindurch erstreckt. FIG. 3 shows an exploded view of the embodiment of the locking device 1 according to the present invention. The locking device 1 initially comprises a base body 15, which is designed as a single part and for receiving and guiding further the locking device 1 forming component corresponding recesses and channels. In particular, the base body 15 has a keyed passage 28, through which the key 10 extends in the inserted into the lock cylinder 11 state.

Zur quer und beabstandet zur Schließzylinderachse 12 erforderlichen FĂŒhrung des Schieberelementes 13 ist im Grundkörper 15 ein Schieberkanal 16 eingebracht. Dieser ist als U-förmige Vertiefung in der Stirnseite des Grundkörpers 15 eingebracht, die zur Anordnung an einen Schließzylinder 11 an diesen angrenzt. Das Schieberelement 13 weist eine Geometrie auf, die komplementĂ€r zur Ausgestaltung des Schieberkanals 16 gebildet ist, um eine FĂŒhrung in Richtung des gezeigten Doppelpfeils im Schieberkanal 16 zu ermöglichen.For transversely and spaced from the lock cylinder axis 12 required guidance of the slide element 13, a slide channel 16 is introduced in the main body 15. This is introduced as a U-shaped recess in the end face of the base body 15, which adjoins the arrangement of a lock cylinder 11 thereto. The slide element 13 has a geometry which is formed complementary to the design of the slide channel 16 in order to allow a guide in the direction of the double arrow shown in the slide channel 16.

Die Arretiervorrichtung 1 umfasst ein Sperrelement 17, das zur Arretierung des SchlĂŒssels 10 in SchlĂŒsselabzugsstellung mit diesem verrastbar ist. Das Sperrelement 17 ist in einer Hubachse 18 gemĂ€ĂŸ des vertikal gezeigten Doppelpfeils hubbeweglich aufgenommen. Befindet sich das Sperrelement 17 in einer Arretierstellung, in der der SchlĂŒssel 10 arretiert ist, so ragt der untere Teil des Sperrelementes 17 in den SchlĂŒsseldurchgang 28 hinein. Soll der SchlĂŒssel 10 freigegeben werden, indem die Verrastung mit dem Sperrelement 17 gelöst wird, bewegt sich das Sperrelement 17 entlang der Hubachse 18 in die nach oben verlaufende Richtung. Um das Sperrelement 17 in die Raststellung vorzuspannen, ist ein Federelement 22 rĂŒckseitig am Sperrelement 17 angeordnet, so dass die zungenartige Unterseite des Sperrelementes 17 in der Ruhestellung in den SchlĂŒsseldurchgang 28 hineinragt, um den SchlĂŒssel 10 zu arretieren.The locking device 1 comprises a blocking element 17 which can be latched to lock the key 10 in key withdrawal position with this. The blocking element 17 is received in a liftable manner in a lifting axis 18 according to the double arrow shown vertically. If the blocking element 17 is in a locking position in which the key 10 is locked, the lower part of the blocking element 17 projects into the keyway 28. If the key 10 is to be released by disengaging the catch with the blocking element 17, the blocking element 17 moves along the lifting axis 18 in the upward direction. In order to bias the blocking element 17 into the detent position, a spring element 22 is arranged on the rear side on the blocking element 17 so that the tongue-like underside of the blocking element 17 protrudes into the keyway 28 in the rest position in order to lock the key 10.

Zur HubbetĂ€tigung des Sperrelementes 17 entlang der Hubachse 18 ist eine Wirkverbindung zwischen dem Schieberelement 13 und dem Sperrelement 17 vorgesehen. HierfĂŒr weist das Schieberelement 13 eine WirkflĂ€che 23 mit einer Rastkerbe 20 auf, wobei das Sperrelement 17 einen Druckzapfen 21 besitzt, welcher mit der WirkflĂ€che 23 und insbesondere mit der Rastkerbe 20 zusammenwirkt. Die Schieberachse 14 verlĂ€uft horizontal und damit senkrecht zur Hubachse 18, so dass das Schieberelement 13 eine Bewegung ausfĂŒhrt, die senkrecht zur Bewegung des Sperrelementes 17 verlĂ€uft. Der Druckzapfen 21 kann dabei mit Rastkerbe 20 in Wechselwirkung treten. Durch die Vorspannung des Sperrelements 17 durch das Federelement 22 wird ein permanenter Kontakt des Druckzapfens 21 mit der der Rastkerbe 20 aufrecht erhalten. Befindet sich das Schieberelement 13 in Mittelstellung, so greift der Druckzapfen 21 in die Mitte der Rastkerbe 20 im Schieberelement 13 ein. Durch die Vertiefung, die durch die Rastkerbe 20 gebildet ist, kann das Sperrelement 17 derart weit in Richtung zum SchlĂŒsseldurchgang 28 bewegt werden, dass der zungenartige Fortsatz des Sperrelementes 17 in den SchlĂŒsseldurchgang 28 hineinragt. Wird das Schieberelement 13 durch DruckbetĂ€tigung entweder in der ersten oder in der zweiten Richtung der Schieberachse 14 bewegt, so wird das Sperrelement 17 entlang der Hubachse 18 nach oben bewegt, so dass der SchlĂŒsseldurchgang 28 vollstĂ€ndig freigegeben wird. In dieser aktivierten Stellung gleitet der Druckzapfen in Richtung zur WirkflĂ€che 23 ab, jedoch wird die WirkflĂ€che 23 nicht vollstĂ€ndig erreicht, sondern der Druckzapfen 21 bleibt derart in Kontakt mit der SchrĂ€ge der Rastkerbe 20, dass eine selbsttĂ€tige RĂŒckstellung des Schieberelementes 13 noch erfolgen kann. Folglich besitzt die Arretiervorrichtung 1 eine Ruhestellung, in der der Druckzapfen 21 in die Rastkerbe 20 mittig eingreift, die nach Loslassen des Schieberelementes 13 grundsĂ€tzlich wieder eingenommen wird.For lifting operation of the blocking element 17 along the lifting axis 18, an operative connection between the slide element 13 and the blocking element 17 is provided. For this purpose, the slider element 13 has an active surface 23 with a latching notch 20, wherein the blocking element 17 has a pressure pin 21 which cooperates with the active surface 23 and in particular with the latching notch 20. The slide axis 14 extends horizontally and thus perpendicular to the lifting axis 18, so that the slide element 13 carries out a movement which is perpendicular to the movement of the blocking element 17. The pressure pin 21 may be with notch 20 interact. By the bias of the locking element 17 by the spring element 22, a permanent contact of the pressure pin 21 with the notch 20 is maintained. If the slide element 13 is in the middle position, then the pressure pin 21 engages in the middle of the latching notch 20 in the slide element 13. Through the depression, which is formed by the latching notch 20, the blocking element 17 can be moved so far in the direction of the keyed passage 28 that the tongue-like extension of the blocking element 17 projects into the keyway 28. If the slide element 13 is moved by pressure actuation either in the first or in the second direction of the slide axis 14, the blocking element 17 is moved upwards along the lifting axis 18, so that the key passage 28 is completely released. In this activated position, the pressure pin slides in the direction of the active surface 23, but the active surface 23 is not completely reached, but the pressure pin 21 remains in contact with the slope of the notch 20 so that an automatic return of the slide element 13 can still be done. Consequently, the locking device 1 has a rest position in which the pressure pin 21 centrally engages in the notch 20, which is basically taken after release of the slide element 13 again.

Zur FĂŒhrung des Schieberelementes 13 und des Sperrelementes 17 ist ein FĂŒhrungselement 24 vorgesehen, welches als Bolzen ausgefĂŒhrt ist und fest im Grundkörper 15 eingebracht wird. Damit die jeweilige BewegungsfĂŒhrung ermöglicht ist, weist das Schieberelement 13 ein Langloch 31 und das Sperrelement 17 ein Langloch 32 auf, wobei sich das FĂŒhrungselement 24 durch die Langlöcher 31 und 32 hindurch erstreckt. Folglich ist zugleich eine Begrenzung der Bewegung des Schieberelementes 13 und des Sperrelementes 17 geschaffen.To guide the slider element 13 and the blocking element 17, a guide element 24 is provided, which is designed as a bolt and is firmly inserted in the base body 15. In order for the respective movement guide to be possible, the slide element 13 has a slot 31 and the blocking element 17 has a slot 32, wherein the guide element 24 extends through the elongated holes 31 and 32. Consequently, at the same time a limitation of the movement of the slider element 13 and the blocking element 17 is created.

Figur 4 zeigt eine Seitenansicht eines SchlĂŒssels 10, der zur Verrastung mit der Arretiervorrichtung 1 ausgefĂŒhrt ist. Der SchlĂŒssel 10 besitzt eine SchlĂŒsselreide 30, die beispielhaft als Kunststoff-Spritzgussbauteil ausgefĂŒhrt ist und aus der sich der SchlĂŒsselbart 29 heraus erstreckt. Am Ansatzende der SchlĂŒsselreide 30 in Richtung zum SchlĂŒsselbart 29 ist eine Rastnase 19 gezeigt, die einteilig mit dem Kunststoff-Spritzgussbauteil der SchlĂŒsselreide 30 ausgefĂŒhrt ist. Das Sperrelement 17 kann in Raststellung hinter die Rastnase 19 eingreifen, so dass in der Bewegung des SchlĂŒssels 10 in Richtung zur SchlĂŒsselreide 30 verhindert ist, wenn der SchlĂŒsselbart 29 in den Schließzylinder 11 eingesteckt ist. Um ein EinfĂŒhren des SchlĂŒssels 10 in den Schließzylinder 11 zu ermöglichen, ohne dass durch Anstoßen der Rastnase 19 gegen das Sperrelement 17 ein Blockieren des SchlĂŒssels 10 in Einsteckrichtung erfolgt, weißt die Rastnase 19 eine AnlaufschrĂ€ge 19a auf. Eine komplementĂ€r ausgefĂŒhrte AnlaufschrĂ€ge kann ferner am Sperrelement 17 vorgesehen sein. Dadurch wird ermöglicht, dass bei Einschieben des SchlĂŒssels 10 in den Schließzylinder 11 das Sperrelement 17 an der AnlaufschrĂ€ge 19a der Rastnase 19 abgleitet und sich in der Hubachse 18 entgegen der Federkraft des Federelementes 22 bewegt. Damit fĂŒhrt das Sperrelement 17 eine Schnappbewegung aus, so dass dieses bei vollstĂ€ndigem Einstecken des SchlĂŒssels 10 in den Schließzylinder 11 hinter die Rastnase 19 eingreift. Die Rastnase 19 ist in dem Winkelsegment am SchlĂŒssel 10 angeordnet, in dem die Rastnase 19 in Richtung zum Sperrelement 17 weist, wenn sich der SchlĂŒssel 10 in SchlĂŒsselabzugsstellung befindet. In einer ĂŒbrigen Stellung außerhalb der SchlĂŒsselabzugsstellung kann der SchlĂŒssel 10 nicht aus dem Schließzylinder 11 entnommen werden, da der SchlĂŒssel 10 durch den Schließzylinderkern und den entsprechenden Zuhaltungen festgehalten ist. FIG. 4 shows a side view of a key 10, which is designed for locking with the locking device 1. The key 10 has a Key 30, which is exemplified as a plastic injection molded component and from which the key bit 29 extends out. At the beginning end of the key 30 in the direction of the key bit 29, a latching lug 19 is shown, which is embodied in one piece with the plastic injection-molded component of the key bit 30. The locking element 17 can engage behind the locking lug 19 in the locking position, so that is prevented in the movement of the key 10 in the direction of the key grain 30 when the key bit 29 is inserted into the lock cylinder 11. In order to allow insertion of the key 10 in the lock cylinder 11 without blocking the key 10 in the plug-in direction by abutment of the latching lug 19 against the blocking element 17, the latching lug 19 has a run-on bevel 19a. A complementarily executed run-on slope can also be provided on the blocking element 17. This makes it possible that upon insertion of the key 10 in the lock cylinder 11, the blocking element 17 slides on the starting slope 19a of the locking lug 19 and moves in the lifting axis 18 against the spring force of the spring element 22. Thus, the locking element 17 performs a snap action, so that this engages with complete insertion of the key 10 in the lock cylinder 11 behind the locking lug 19. The latching lug 19 is arranged in the angle segment on the key 10, in which the latching lug 19 points in the direction of the blocking element 17 when the key 10 is in the key withdrawal position. In a remaining position outside the key withdrawal position, the key 10 can not be removed from the lock cylinder 11, since the key 10 is held by the lock cylinder core and the corresponding tumblers.

Die Figuren 5 und 6 zeigen eine Draufsicht auf die Arretiervorrichtung 1, wobei diese in Figur 5 in der Ruhestellung und in Figur 6 in einer aktivierten Stellung gezeigt ist. Die Arretiervorrichtung 1 ist mit dem Grundkörper 15 dargestellt, in dem sowohl das Schieberelement 13 als auch das Sperrelement 17 in einer durch das FĂŒhrungselement 24 eingebauten und befestigten Anordnung gezeigt ist. In der Ruhestellung befindet sich der Druckzapfen 21 in der Rastkerbe 20, die im Schieberelement 13 eingebracht ist. Die Rastkerbe 20 ist mittig auf der WirkflĂ€che 23 eingebracht, wobei der Druckzapfen 21 eine erste Flanke 21a und eine gegenĂŒberliegende zweite Flanke 21 b aufweist, durch die der Druckzapfen 21 V-förmig ausgefĂŒhrt ist. Die V-Form wiederholt sich in der Rastkerbe 20, wobei die V-Öffnung der Rastkerbe 20 mit einem grĂ¶ĂŸeren Winkel ausgefĂŒhrt ist als der Winkel zwischen der ersten Flanke 21 a und der zweiten Flanke 21 b.The FIGS. 5 and 6 show a plan view of the locking device 1, wherein these in FIG. 5 at rest and in FIG. 6 is shown in an activated position. The locking device 1 is shown with the base body 15, in which both the slider element 13 and the blocking element 17 in a built-in by the guide member 24 and attached arrangement is shown. In the rest position, the pressure pin 21 is located in the notch 20, which is incorporated in the slider element 13. The latching notch 20 is centrally placed on the active surface 23, wherein the pressure pin 21 has a first flank 21a and an opposite second flank 21b, through which the pressure pin 21 is designed V-shaped. The V-shape is repeated in the notch 20, wherein the V-opening of the notch 20 is designed with a larger angle than the angle between the first edge 21 a and the second edge 21 b.

Das Schieberelement 13 weist endseitig Drucktaster 13a und 13b auf, ĂŒber die das Schieberelement 13 manuell betĂ€tigt werden kann. Wird beispielsweise auf den Drucktaster 13b ein Druck ausgeĂŒbt, so verlagert sich das Schieberelement 13 in der Bildebene gemĂ€ĂŸ Figur 6 nach links. Damit wandert der Druckzapfen 21 durch einen Kontakt des Druckzapfens 21 mit der Rastkerbe 20 ĂŒber die zweite Flanke 21 in der Hubachse 18 nach oben. Damit wird das Sperrelement 17 wenigstens teilweise aus dem SchlĂŒsseldurchgang 28 herausgezogen. Wird das Schieberelement 13 wieder losgelassen, so stellt sich dieses durch Druckkontakt des Druckzapfens 21 ĂŒber die zweite Flanke 21 b auf die Rastkerbe 20 wieder in die Mittelstellung, wie diese in Figur 5 gezeigt ist. Um die RĂŒckstellung zu bewirken, dient die Federkraft 22, so dass ein A-stabiler Gleichgewichtszustand des Schieberelementes 13 und damit das Sperrelement 17 in Sperrstellung erreicht wird.The slide element 13 has end push buttons 13a and 13b, via which the slide element 13 can be manually operated. For example, if a pressure is exerted on the pushbutton 13b, then the slider element 13 moves in the image plane according to FIG FIG. 6 to the left. Thus, the pressure pin 21 moves by contact of the pressure pin 21 with the notch 20 via the second edge 21 in the lifting axis 18 upwards. Thus, the blocking element 17 is at least partially pulled out of the keyway 28. If the slider element 13 is released again, this is due to pressure contact of the pressure pin 21 on the second edge 21 b on the notch 20 back to the middle position, as in FIG. 5 is shown. To effect the return, the spring force 22, so that an A-stable state of equilibrium of the slider element 13 and thus the locking element 17 is achieved in the locked position.

Der Grundkörper 15 ist scheibenförmig ausgefĂŒhrt und weist eine UmfangsflĂ€che 15a auf, in die sich die Drucktaster 13a und 13b integrieren, die endseitig am Schieberelement 13 angeformt sind. Der Grundkörper 15 besitzt ferner Durchgangslöcher 25, um eine Verschraubung der Arretiervorrichtung 1 mit dem Schließzylinder 11 zu ermöglichen.The main body 15 is designed disk-shaped and has a peripheral surface 15 a, in which the push-buttons integrate 13 a and 13 b, which are integrally formed on the slide element 13. The main body 15 further has through holes 25 to allow a screwing of the locking device 1 with the lock cylinder 11.

Die Erfindung beschrĂ€nkt sich in ihrer AusfĂŒhrung nicht auf das vorstehend angegebene bevorzugte AusfĂŒhrungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsĂ€tzlich anders gearteten AusfĂŒhrungen Gebrauch macht. Beispielsweise kann das Schieberelement 13 zwei unterschiedlich tiefe Rastkerben aufweisen, wobei eine erste Rastkerbe eine Tiefe aufweist, in der das Sperrelement 17 sich derart weit in den SchlĂŒsseldurchgang 28 hinein erstrecken kann, dass ein SchlĂŒssel 10 im Schließzylinder 11 arretiert ist. Wird das Schieberelement 13 derart bewegt, dass der Druckzapfen 21 mit der zweiten, weniger tiefen Rastkerbe in Überdeckung gebracht wird, so ragt das Sperrelement 17 nicht oder nur mit einer geringen Tiefe in den SchlĂŒsseldurchgang 28 hinein, so dass der SchlĂŒssel 10 weiterhin entlang der Schließzylinderachse 12 frei beweglich bleibt und nicht arretiert ist. Damit entsteht ein Bi-stabiler Zustand des Schieberelementes 13 und folglich des Sperrelementes 17, so dass der SchlĂŒssel 10 in einer ersten Stellung des Schieberelementes 13 arretiert ist und in einer zweiten Stellung trotz vorhandener Arretiervorrichtung 1 freigegeben ist, ohne dass diese betĂ€tigt wird.The invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number Variants conceivable, which makes use of the illustrated solution even with fundamentally different types of execution. For example, the slider element 13 may have two differently deep notches, wherein a first notch has a depth in which the locking element 17 can extend so far into the keyway 28 in that a key 10 is locked in the lock cylinder 11. If the slider element 13 is moved such that the pressure pin 21 is brought into coincidence with the second, less deep notch, the blocking element 17 does not protrude into the keyway 28 or only with a small depth, so that the key 10 continues along the lock cylinder axis 12 remains free to move and is not locked. This results in a bi-stable state of the slide element 13 and consequently of the blocking element 17, so that the key 10 is locked in a first position of the slide element 13 and is released in a second position despite existing locking device 1, without this being actuated.
