Description

Die Erfindung betrifft eine Schließeinrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a locking device according to the preamble of claim 1.

Zum Sperren eines Schlosses ist üblicherweise ein Betätigungsglied bzw. eine Handhabe vorgesehen, wie beispielsweise ein Türgriff, ein Türknauf, ein Schlüssel oder dergleichen, dessen Bewegung entweder unmittelbar oder unter Zwischenschaltung einer Kupplungseinrichtung mit dem Schließglied, wie beispielsweise einer Sperrnase oder einem Sperrriegel, zum Öffnen oder Schließen des Schlosses gekuppelt ist, wobei die Kupplungseinrichtung das Betätigungsglied mit dem Schließglied in der Regel nur dann kuppelt, wenn eine Zutrittsberechtigung festgestellt wurde. Die Zutrittsberechtigung wird bei elektronisch arbeitenden Schließeinrichtungen durch elektronische Zutrittskontrollmittel gesteuert, bei denen eine Identifizierung mittels eines elektronischen Codes festgestellt wird. Die Kupplungseinrichtung wird meist durch Motoren oder elektromagnetisch angetrieben, um zwischen einer Ineingriffs- und einer Außereingriffslage bewegt zu werden.For locking a lock usually an actuator or a handle is provided, such as a door handle, a door knob, a key or the like, the movement either directly or with the interposition of a coupling device with the closing member, such as a locking lug or a locking latch to open or closing the lock is coupled, wherein the coupling device usually couples the actuator with the closing member only when an access authorization has been established. The access authorization is controlled by electronically operated locking devices by electronic access control means, in which an identification by means of an electronic code is detected. The coupling device is usually driven by motors or electromagnetically driven to be moved between an engaged and disengaged position.

Die elektronischen Zutrittskontrollmittel umfassen meist eine Leseeinheit zum Auslesen von Zutrittsrechtsdaten aus einem Identmedium, eine Auswerteschaltung zur Feststellung der Zutrittsberechtigung in Abhängigkeit von den Zutrittsrechtsdaten und eine mit der Auswerteschaltung zusammenwirkenden Logikeinheit zur Ansteuerung der Kupplungsmittel, wobei zumindest ein Element ausgewählt aus Leseeinheit, Auswerteschaltung und Logikeinheit in der Handhabe angeordnet und mit einem in dem Schließzylinder angeordneten Element elektrisch verbunden ist. Es ist beispielsweise die Kupplungseinrichtung samt der zugeordneten Logikeinheit in dem Schließzylinder angeordnet und muss zu deren Ansteuerung und ggf. Energieversorgung elektrisch mit der Handhabe verbunden werden, in der zumindest ein Teil der anderen Komponenten der elektronischen Zutrittskontrolle und ggf. auch der Energiespeicher angeordnet sind. Die Handhabe muss für Montage- und Demontagezwecke, aber ggf. auch zum Auswechseln des Energiespeichers lösbar mit dem Zylinderkern verbunden werden, sodass neben den elektrischen auch mechanische Verbindungsmittel vorgesehen sind. Die lösbare mechanische und elektrische Verbindung ermöglicht weiters die Ausbildung eines modularen Systems, bei dem ein Schließzylinder wahlweise mit einem aus einer Mehrzahl von unterschiedlich ausgebildeten Handhaben verbunden werden kann, beispielsweise um unterschiedlichen Datenübertragungstechnologien für das Auslesen der Zutrittsrechtsdaten aus einem Identmedium Rechnung zu tragen.The electronic access control means usually comprise a reading unit for reading access rights data from a ID medium, an evaluation circuit for determining the access authorization in dependence on the access right data and a cooperating with the evaluation logic unit for controlling the coupling means, wherein at least one element selected from the reading unit, evaluation circuit and logic unit in the handle is arranged and electrically connected to a arranged in the lock cylinder element. It is, for example, arranged the coupling device together with the associated logic unit in the lock cylinder and must be electrically connected to the control and possibly power supply to the handle, in the at least one part the other components of the electronic access control and possibly also the energy storage are arranged. The handle must be connected for assembly and disassembly purposes, but possibly also for replacing the energy store releasably connected to the cylinder core, so that in addition to the electrical and mechanical connection means are provided. The releasable mechanical and electrical connection further allows the formation of a modular system in which a lock cylinder can be selectively connected to one of a plurality of differently designed handles, for example, to accommodate different data transmission technologies for reading the access right data from a ID medium.

Sowohl in der DE 10 2004 009 992 A1 als auch in der EP 1 908 898 A1 wird eine elektronische Schließeinrichtung mit einem elektronischen Schließzylinder und einer Handhabe in Form eines Knaufs beschrieben.Both in the DE 10 2004 009 992 A1 as well as in the EP 1 908 898 A1 An electronic locking device is described with an electronic lock cylinder and a handle in the form of a knob.

Weiters beschreibt die EP 1 739 631 A1 allgemein einen Schließzylinder mit Knauf, wobei im Knauf eine Leseeinheit räumlich getrennt von der Auswerteelektronik angeordnet ist, welche beispielsweise im Schließzylindergehäuse selbst oder in der Rosette an einer Seite des Schließzylinders untergebracht sein kann.Further describes the EP 1 739 631 A1 In general, a lock cylinder with knob, wherein a reading unit is spatially separated from the evaluation arranged in the knob, which may be housed for example in the lock cylinder housing itself or in the rosette on one side of the lock cylinder.

Die vorliegende Erfindung zielt nun darauf ab, die mechanische Verbindung zwischen der Handhabe und dem Schließzylinder in einer Weise auszuführen, dass die Verbindung zwar einfach gelöst werden kann, aber trotzdem überaus stabil ist und hohen mechanischen Belastungen beispielsweise bei Manipulationsversuchen oder dgl. standhält. Weiters soll die mechanische Verbindung in einfacher Weise mit einer elektrischen Verbindung kombiniert werden, sodass bei einem Herstellen der mechanischen Verbindung automatisch auch die elektrische Verbindung hergestellt und umgekehrt bei einem Lösen der mechanischen Verbindung gleichzeitig auch die elektrische Verbindung getrennt wird.The present invention now aims to make the mechanical connection between the handle and the lock cylinder in a way that, although the connection can be easily solved, but still is extremely stable and withstand high mechanical loads, for example in tampering or the like. Furthermore, the mechanical connection should be combined with an electrical connection in a simple manner, so that the electrical connection is automatically established when the mechanical connection is made and conversely, upon release of the mechanical connection, the electrical connection is disconnected at the same time.

Zur Lösung dieser Aufgabe ist die Schließeinrichtung im Wesentlichen derart ausgebildet, dass die Verbindungsmittel eine Gewindeverbindung zwischen Zylinderkern und Handhabe umfassen, wobei die Gewindeverbindung eine formschlüssige Verdrehsicherung in der Form von an dem Zylinderkern oder der Handhabe angeordneten axialen Ausnehmungen aufweist, in die an dem anderen Teil ausgebildete Vorsprünge im verschraubten Zustand der Gewindeverbindung axial eingreifen können, wobei die Vorsprünge und/oder die Ausnehmungen axial verschiebbar angeordnet sind. Die Verdrehsicherung erlaubt es, eine bewährte Gewindeverbindung für die mechanische Verbindung der Handhabe mit dem Schließzylinder einzusetzen, ohne dass Nachteile hinsichtlich der Drehfestigkeit der Verbindung in Kauf genommen werden müssen. Es kann auf nachteilige Steck- oder Rastverbindungen verzichtet werden. Die Vorsprünge und Ausnehmungen sind insbesondere so angeordnet, dass die Vorsprünge bei Erreichen eines verschraubten Zustandes selbsttätig in die Ausnehmungen formschlüssig eingreifen bzw. einrasten. Dies ist insbesondere dann sichergestellt, wenn, wie dies einer bevorzugten Weiterbildung entspricht, die Vorsprünge und/oder die Ausnehmungen axial in Eingriffsrichtung federbeaufschlagt sind. Auf Grund der Erfindung sind gesondert zu montierende Sicherungsmittel, wie z.B. Sicherungsstifte, Madenschrauben oder dgl. nicht erforderlich.To achieve this object, the closing device is essentially designed such that the connecting means comprise a threaded connection between the cylinder core and the handle, wherein the threaded connection has a form-locking anti-rotation in the form of arranged on the cylinder core or the handle axial recesses into which on the other part formed projections in the screwed state of the threaded connection can engage axially, wherein the projections and / or the recesses are arranged axially displaceable. The anti-rotation device makes it possible to use a proven threaded connection for the mechanical connection of the handle with the lock cylinder, without having to accept disadvantages with regard to the rotational strength of the connection. It can be dispensed with disadvantageous plug or snap connections. The projections and recesses are arranged in particular so that the projections automatically engage or snap into the recesses when a screwed state is reached. This is ensured in particular if, as corresponds to a preferred development, the projections and / or the recesses are spring-loaded axially in the direction of engagement. By virtue of the invention, securing means to be mounted separately, e.g. Locking pins, set screws or the like not required.

Bevorzugt ist vorgesehen, dass wenigstens drei Ausnehmungen und Vorsprünge in Umfangsrichtung verteilt angeordnet sind. Bevorzugt sind die wenigstens drei Ausnehmungen gleichmäßig über den Umfang des Gewindes verteilt, sodass die Vorsprünge in einer der Umfangsteilung entsprechenden Anzahl an Drehlagen in Eingriff mit den Ausnehmungen gebracht werden können. Bevorzugt sind wenigstens vier, insbesondere wenigstens sechs Vorsprünge und Ausnehmungen vorgesehen.It is preferably provided that at least three recesses and projections are arranged distributed in the circumferential direction. Preferably, the at least three recesses are distributed uniformly over the circumference of the thread, so that the projections can be brought into engagement with the recesses in a number of rotational positions corresponding to the circumferential pitch. Prefers At least four, in particular at least six projections and recesses are provided.

Grundsätzlich können die Vorsprünge entweder an der Handhabe oder am Zylinderkern und die Ausnehmungen am jeweils anderen Teil angeordnet werden. Aufgrund der begrenzten Platzverhältnisse im Zylinderkern ist es aber vorteilhaft, wenn die Vorsprünge an der Handhabe und die Ausnehmungen am Zylinderkern ausgebildet sind. Dies insbesondere wenn, wie dies einer weiteren bevorzugten Weiterbildung entspricht, die Gewindeverbindung ein an einer Stirnseite der Handhabe, insbesondere an einer den Deckel eines topförmigen Knaufs bildenden Platte, ausgebildetes Innengewinde und ein am Zylinderkern ausgebildetes Außengewinde umfasst.In principle, the projections can be arranged either on the handle or on the cylinder core and the recesses on the respective other part. Due to the limited space in the cylinder core, it is advantageous if the projections on the handle and the recesses are formed on the cylinder core. This in particular if, as corresponds to a further preferred development, the threaded connection comprises an internal thread formed on an end face of the handle, in particular on a plate forming the lid of a pot-shaped knob, and an external thread formed on the cylinder core.

Die Vorsprünge sind hierbei vorteilhafterweise an einem hinter der Stirnseite der Handhabe, insbesondere hinter der den Deckel des Knaufs bildenden Platte, angeordneten Bauteil ausgebildet, wobei die Vorsprünge in Ausnehmungen des Innengewindes formschlüssig eingreifen und radial in die lichte Weite des Innengewindes hineinragen. Dadurch wird der die Vorsprünge tragende Teil in konstruktiv einfacher Weise ebenfalls formschlüssig und verdrehgesichert gehalten.The projections are in this case advantageously formed on a behind the end face of the handle, in particular behind the cover of the knob forming plate, arranged component, wherein the projections engage in recesses of the internal thread positively and protrude radially into the inside diameter of the internal thread. As a result, the part carrying the projections is also held positively in a structurally simple manner and secured against rotation.

Um zu ermöglichen, dass die Vorsprünge erst nach einem möglichst vollständigen Verschrauben der Handhabe mit dem Zylinderkern formschlüssig in die Ausnehmungen eingreifen, muss eine Möglichkeit geschaffen werden, die Vorsprünge wegzudrücken und erst nach dem Verschraubungsvorgang eingreifen zu lassen. Die Ausbildung ist in diesem Zusammenhang bevorzugt derart getroffen, dass der die Vorsprünge tragende Bauteil radial außerhalb des Gewindes angeordnete Sicherungsstifte aufweist, die in Ausnehmungen an der Stirnseite der Handhabe, insbesondere in einer den Deckel eines topförmigen Knaufs bildenden Platte, eingreifen. Die Sicherungsstifte sind hierbei von außen mittels eines Werkzeuges zurückdrückbar angeordnet, sodass die Vorsprünge während des Einschraubvorgangs unter Verwendung eines Spezialwerkzeugs in eine Position gebracht werden können, in der sie nicht in Eingriff in die Ausnehmungen gelangen können. Erst nachdem die Handhabe vollständig bis zum Anschlag auf den Zylinderkern aufgeschraubt wurde, werden die Sicherungsstifte losgelassen und die Vorsprünge auf Grund der Federkraft in Richtung zu den Ausnehmungen beaufschlagt. Ein Zurückdrehen der Handhabe um einen bestimmten Winkel führt dazu, dass die Vorsprünge bei Erreichen einer mit den Ausnehmungen überdeckenden Position in diese automatisch eingreifen, um auf diese Art die formschlüssige Verdrehsicherung zu realisieren. Je größer die Anzahl der in Umfangsrichtung verteilten Vorsprünge und Ausnehmungen ist, desto geringer ist der bis zum Einrasten der Vorsprünge in die Ausnehmungen erforderliche Rückdrehwinkel.In order to enable the projections to engage in a form-fitting manner into the recesses only after screwing the handle with the cylinder core as completely as possible, a possibility must be provided for pushing the projections away and for engaging only after the screwing procedure. The training is preferably made in this context such that the component carrying the projections has radially outwardly of the threaded locking pins, which in recesses on the end face of the handle, in particular in a the lid of a pot-shaped knob forming plate, intervene. The locking pins are in this case arranged back from the outside by means of a tool, so that the projections can be brought during the screwing using a special tool in a position in which they can not get into engagement with the recesses. Only after the handle has been completely screwed to the stop on the cylinder core, the locking pins are released and the projections acted upon by the spring force in the direction of the recesses. A turning back of the handle by a certain angle causes the projections automatically engage in reaching a covering with the recesses position in this, in order to realize in this way the positive rotation. The greater the number of circumferentially distributed projections and recesses, the lower is the required until the projections engage in the recesses return angle.

Bevorzugt weisen die Verbindungsmittel durch die Gewindeverbindung hindurchgeführte elektrische Kontaktierungsmittel auf, sodass gleichzeitig mit der mechanischen auch die elektrische Verbindung hergestellt werden kann. Die elektrischen Kontaktierungsmittel weisen dabei wenigstens zwei in unterschiedlichem radialen Abstand von der Drehachse des Zylinderkerns angeordnete elektrische Kontakte und auf entsprechendem Durchmesser liegende ringförmige Gegenkontakte auf. Die ringförmige Ausbildung der Gegenkontakte stellt sicher, dass die elektrische Kontaktierung unabhängig von der jeweiligen Drehlage der Handhabe relativ zum Zylinderkern hergestellt ist. Wenn die elektrischen Kontakte als federnde Kontaktstifte ausgebildet sind, wirken die Kontaktstifte mit den ringförmigen Gegenkontakten beim Verschrauben der Handhabe mit dem Zylinderkern nach Art von Schleifkontakten zusammen.The connection means preferably have electrical contacting means guided through the threaded connection, so that the electrical connection can be established simultaneously with the mechanical connection. In this case, the electrical contacting means have at least two electrical contacts arranged at different radial distances from the axis of rotation of the cylinder core and annular countercontacts lying at the corresponding diameter. The annular design of the mating contacts ensures that the electrical contact is made independently of the respective rotational position of the handle relative to the cylinder core. If the electrical contacts are designed as resilient contact pins, the contact pins interact with the annular mating contacts when screwing the handle with the cylinder core in the manner of sliding contacts.

Bevorzugt sind die ringförmigen Gegenkontakte als Leiterbahnen auf einem Träger, insbesondere einer Trägerfolie ausgebildet.Preferably, the annular mating contacts are designed as conductor tracks on a carrier, in particular a carrier foil.

Bevorzugt sind die elektrischen Kontakte am Zylinderkern und die Gegenkontakte an der Handhabe angeordnet.Preferably, the electrical contacts on the cylinder core and the mating contacts are arranged on the handle.

Gemäß einer vorteilhaften Weiterbildung sind wenigstens drei elektrische Kontakte und zugeordnete Gegenkontakte vorgesehen, wobei zwei Kontakte der Energieübertragung von einem in der Handhabe angeordnetem elektrischen Energiespeicher zu dem Kupplungsmittel und wenigstens ein Kontakt der Signal- bzw. Datenübertragung dient.According to an advantageous development, at least three electrical contacts and associated mating contacts are provided, wherein two contacts of the energy transfer from an arranged in the handle electrical energy storage to the coupling means and at least one contact of the signal or data transmission is used.

Wenn die Leseeinheit und die Auswerteschaltung in der Handhabe und die Logikeinheit im Schließzylinder angeordnet sind, dient die elektrische Verbindung zwischen der Handhabe und dem Zylinderkern unter anderem der Übertragung von Steuerbefehlen der Logikschaltung, um die Kupplungsmittel zu betätigen.When the reading unit and the evaluation circuit are arranged in the handle and the logic unit in the lock cylinder, the electrical connection between the handle and the cylinder core, inter alia, the transmission of control commands of the logic circuit to actuate the coupling means.

Die Erfindung kann im Rahmen von verschiedenen Ausbildungen der Schließeinheit zum Einsatz gelangen. Es ist daher bevorzugt vorgesehen, dass die Schließeinheit als Doppelknaufschließzylinder, Schließzylinder mit lediglich einem Knauf, mit oder ohne Schlüsselsteckfunktion auf der dem Knauf gegenüberliegenden Schließzylinderseite, Doppelschließzylinder, Doppelschließzylinder mit beidseitiger elektronischer oder mechatronischer Berechtigungsabfrage, Halbzylinder, Halbzylinder mit Knauf, Halbzylinder mit mechatronischer Berechtigungsabfrage oder Halbzylinder mit elektronischer Berechtigungsabfrage ausgebildet ist.The invention can be used within the scope of various embodiments of the clamping unit.

In dieser zeigt Fig. 1 einen Schließzylinder, Fig. 2 einen Knauf, Fig. 3 den Schließzylinder aus Fig. 1 mit einem vorderen Teil des Knaufs, Fig. 4 den Schließzylinder mit aufgeschraubtem Knauf und einem Montierwerkzeug und Fig. 5 das Montierwerkzeug in angesetztem Zustand.The invention will be explained in more detail with reference to an embodiment shown in the drawing.

Mit dem frei drehbaren Teil 5 kann ein Drehknauf 6 drehfest verbunden werden, sodass die Drehbewegung des Drehknaufs 6 stets auf den frei drehbaren Teil 5 des Zylinderkerns 3 übertragen wird. Mit dem hinteren Teil des Zylinderkerns 3 ist eine nicht dargestellt Schließnase oder dgl. drehfest verbunden. Sobald der frei drehbare Teil 5 des Zylinderkerns 3 mittels der Kupplung 4 in drehfeste Wirkverbindung mit dem hinteren Teil des Zylinderkerns 3 gebracht wird, bewirkt eine Verdrehung des Drehknaufs 6 eine Betätigung der Sperrnase, sodass ein nicht näher dargestelltes Schloss geöffnet werden kann. Die Kupplung 4 wird hierbei von einer Logikeinheit 7 angesteuert, die mittels dreier elektrischer Leitungen 9 mit einer in dem Drehknauf 6 angeordneten Auswerteschaltung 8 elektrisch verbunden ist.In Fig. 1 the lock cylinder is denoted by 1 and has a lock cylinder housing 2 and a cylinder core 3 rotatably received in the lock cylinder housing 2. The cylinder core 3 consists of two axially successively arranged parts and takes on a schematically indicated clutch 4, with which the front part 5 of the cylinder core 3 rotatably connected to the rear part and the rotationally fixed connection can be released again. The front, protruding from the cylinder housing 2 Part 5 is always freely rotatably mounted in the lock cylinder housing 2. With the freely rotatable part 5, a rotary knob 6 can be rotatably connected, so that the rotational movement of the rotary knob 6 is always transmitted to the freely rotatable part 5 of the cylinder core 3. With the rear part of the cylinder core 3 is not shown closing lug or the like. Non-rotatably connected. As soon as the freely rotatable part 5 of the cylinder core 3 is brought into non-rotatable operative connection with the rear part of the cylinder core 3 by means of the coupling 4, a rotation of the rotary knob 6 causes an actuation of the locking nose, so that a lock (not shown) can be opened. The clutch 4 is in this case controlled by a logic unit 7, which is electrically connected by means of three electrical lines 9 with an arranged in the rotary knob 6 evaluation circuit 8.

Die drehfeste Verbindung des Zylinderkerns 3 mit dem Drehknauf 6 erfolgt über eine Gewindeverbindung, die ein Außengewinde 10 an dem vorragenden Abschnitt des frei drehbaren Teils 5 und ein Innengewinde 11 (Fig. 2) an einer stirnseitigen Platte 14 des Drehknaufs 6 umfasst. Zur Verdrehsicherung der Gewindeverbindung sind am freien Ende des Teils 5 sechs in Umfangsrichtung regelmäßig verteilte Ausnehmungen 12 vorgesehen, in welche im verschraubten Zustand entsprechende Vorsprünge 13 des Drehknaufs 6 axial eingreifen. Die Vorsprünge 13 sind an einem hinter der den Deckel des Drehknaufs 6 bildenden Platte 14 angeordneten plattenförmigen Bauteil 15 ausgebildet. Die Anordnung des Bauteils 15 ist am besten in Fig. 3 ersichtlich, in welcher der Bauteil 15 so wie in Fig. 1 der besseren Übersichtlichkeit halber nicht in der Einbaulage, sondern nach links versetzt dargestellt ist. In Fig. 3 ist ersichtlich, dass der Bauteil 15 an der dem Schließzylinder 1 zugewandten Seite drei in Umfangsrichtung regelmäßig verteilte Sicherungsstifte 16 trägt. Die Sicherungsstifte 16 greifen in Ausnehmungen 17 der Platte 14 ein, damit der plattenförmige Bauteil 15 in Bezug auf den Drehknauf 6 bzw. die Platte 14 in einem drehfesten Zustand gehalten wird. Wie dies in Fig. 2 ersichtlich ist, ragen die Spitzen der Sicherungsstifte 16 aus den Ausnehmungen 17 hervor, d.h. sie stehen aus der Platte 14 heraus. Die Sicherungsstifte 16 dienen gleichzeitig als Montage- und Demontagehilfe. Der plattenförmige Bauteil 15 ist nämlich in axialer Richtung verschiebbar gelagert und mittels eines nicht dargestellten Federelements in Richtung zur Platte 14 beaufschlagt. Wenn nun das in Fig. 4 dargestellte Montagewerkzeug 18 angesetzt wird (Fig. 5), können die Sicherungsstifte 16 und mit ihnen das plattenförmige Bauteil 15 zurückgeschoben werden, sodass die Vorsprünge 13 in Bezug auf die Ausnehmungen 12 außer Eingriff gelangen. In dieser Stellung ist die Verdrehsicherung der Gewindeverbindung gelöst und der Drehknauf 6 kann vom Schließzylinder 1 heruntergeschraubt werden. Nach dem Entfernen des Montagewerkzeugs 18 kehrt das Bauteil 15 samt den Sicherungsstiften 17 auf Grund der Federkraft in seine ursprüngliche Position zurück.The rotationally fixed connection of the cylinder core 3 with the rotary knob 6 via a threaded connection, the external thread 10th on the projecting portion of the freely rotatable part 5 and an internal thread 11 (FIG. Fig. 2 ) on an end plate 14 of the rotary knob 6 includes. To prevent rotation of the threaded connection six circumferentially regularly distributed recesses 12 are provided at the free end of the part, in which corresponding projections 13 of the rotary knob 6 engage axially in the screwed state. The projections 13 are formed on a behind the lid of the knob 6 forming plate 14 arranged plate-shaped member 15. The arrangement of the component 15 is best in Fig. 3 can be seen, in which the component 15 as in Fig. 1 the sake of clarity not in the installed position, but shown offset to the left. In Fig. 3 It can be seen that the component 15 on the side facing the lock cylinder 1 carries three circumferentially regularly distributed locking pins 16. The locking pins 16 engage in recesses 17 of the plate 14, so that the plate-shaped member 15 is held in relation to the rotary knob 6 and the plate 14 in a rotationally fixed state. Like this in Fig. 2 it can be seen protrude the tips of the locking pins 16 from the recesses 17, ie they stand out of the plate 14. The locking pins 16 simultaneously serve as assembly and disassembly aid. The plate-shaped component 15 is in fact displaceably mounted in the axial direction and acted upon by means of a spring element, not shown, in the direction of the plate 14. If now that in Fig. 4 shown assembly tool 18 is set ( Fig. 5 ), the locking pins 16 and with them the plate-shaped member 15 can be pushed back, so that the projections 13 with respect to the recesses 12 are disengaged. In this position, the rotation of the threaded connection is released and the knob 6 can be screwed down from the lock cylinder 1. After removing the assembly tool 18 returns the component 15 together with the locking pins 17 due to the spring force in its original position.

Das Montagewerkzeug 18 wird auch für das Anschrauben des Drehknaufs 6 verwendet. Zuerst werden die Sicherungsstifte 16 mit dem Montagewerkzeug 18 zurückgeschoben. Danach wird der Drehknauf 6 auf den Schließzylinder 1 bis zum Anschlag aufgeschraubt. Danach wird das Montagewerkzeug 18 entfernt, sodass nun die Federkraft den plattenförmigen Bauteil 15 in Richtung zum Schließzylinder 1 beaufschlagt. Danach wird der Drehknauf 6 ein wenig zurückgedreht bis die Vorsprünge 13 auf Grund der Federkraft in die Ausnehmungen 12 eintauchen und dadurch eine weiteres Rückschrauben verhindern.The assembly tool 18 is also used for screwing the knob 6. First, the locking pins 16 are pushed back with the mounting tool 18. Thereafter, the knob 6 is screwed onto the lock cylinder 1 until it stops. Thereafter, the assembly tool 18 is removed, so that now the spring force acts on the plate-shaped component 15 in the direction of the lock cylinder 1. Thereafter, the knob 6 is turned back a little until the projections 13 dive due to the spring force in the recesses 12 and thereby prevent further screwing back.

In Fig. 2 ist schematisch angedeutet, dass im Inneren des Drehknaufs 6 eine Leseeinheit 19 und eine Batterie 20 eingebaut sind. Die Batterie 20 versorgt die Leseeinheit 19 sowie die Auswerteschaltung 8 mit Strom. Die Leseeinheit 19 kann Identifikationsdaten eines elektronischen Schlüssels empfangen und diese an die Auswerteschaltung 8 weitergeben, wo sie hinsichtlich einer Zutrittsberechtigung überprüft werden. Sofern die Überprüfung erfolgreich war, wird die Logikeinheit 7 angesteuert und die Kupplung 4 wird betätigt.In Fig. 2 is schematically indicated that inside the rotary knob 6, a reading unit 19 and a battery 20 are installed. The battery 20 supplies the reading unit 19 and the evaluation circuit 8 with power. The reading unit 19 can receive identification data of an electronic key and forward it to the evaluation circuit 8, where it is checked for access authorization. If the check was successful, the logic unit 7 is activated and the clutch 4 is actuated.

Die elektrische Verbindung zwischen der Auswerteschaltung 8 und der Logikeinheit 7 erfolgt mittels elektrischer Kontakte, die als federnde Kontaktstifte 21 ausgebildet sind und die mit zwei ringförmigen Gegenkontakten 22 und einem kreisförmigen mittigen Gegenkontakt 23 zusammenwirken. Die Kontaktstifte 21 sind mit den elektrischen Leitungen 9 und die Gegenkontakte 22,23 mit den elektrischen Leitungen 24 verbunden. Die Kontaktstifte sind dabei in unterschiedlichem radialen Abstand von der zentralen Achse angeordnet, sodass die elektrische Kontaktierung unabhängig von der gegenseitigen Drehlage von Drehknauf 6 und Schließzylinder 1 gegeben ist.The electrical connection between the evaluation circuit 8 and the logic unit 7 by means of electrical contacts, which are designed as resilient contact pins 21 and which cooperate with two annular mating contacts 22 and a circular central mating contact 23. The contact pins 21 are connected to the electrical leads 9 and the mating contacts 22,23 to the electrical leads 24. The contact pins are arranged at different radial distance from the central axis, so that the electrical contact independently given by the mutual rotational position of knob 6 and lock cylinder 1.
