An electromechanical converter (44) is provided for the operating body (24; 40), which converts an operation (30) of the operating body (24; 40) into electrical energy which is used for wireless communication (32) to the transponder and/or, on receipt of a valid identification signal, for support of the connection of the coupling (34).

Description

Die vorliegende Erfindung betrifft einen Schließzylinder zum Einbau in ein Schloss, mit einem Schließglied zum Betätigen eines Schlossriegels oder dergleichen, und einem Betätigungsglied, wobei das Betätigungsglied im Normalfall von dem Schließglied entkuppelt ist, und mit einer Kupplung zum Verbinden des Schließgliedes mit dem Betätigungsglied nach Erhalt eines Identifikationscodes von einem zugeordneten Transponder, und mit einem elektromechanischen Wandler, der eine Betätigung des Betätigungsgliedes in elektrische Energie umsetzt, die dazu verwendet wird, die drahtlose Kommunikation mit dem Transponder und/oder bei Empfang eines gültigen Identifikationssignals das Einkuppeln der Kupplung zu unterstützten.The present invention relates to a lock cylinder for installation in a lock, comprising a closure member for actuating a lock bolt or the like, and an actuator, wherein the actuator is normally decoupled from the closure member, and a coupling for connecting the closure member to the actuator upon receipt an identification code from an associated transponder, and an electromechanical transducer that converts actuation of the actuator into electrical energy used to facilitate wireless communication with the transponder and / or upon receipt of a valid identification signal, to engage the clutch.

Ferner betrifft die vorliegende Erfindung ein Verfahren zum Durchführen eines Schließvorganges eines Schlosses, insbesondere einer Tür.Furthermore, the present invention relates to a method for performing a closing operation of a lock, in particular a door.

Bei dem gattungsgemäßen Schließzylinder handelt es sich um einen sogenannten elektronischen Schließzylinder. Der Schließzylinder kann beispielsweise ein Profilzylinder sein.In the generic lock cylinder is a so-called electronic lock cylinder. The lock cylinder may for example be a profile cylinder.

Herkömmliche Schließzylinder weisen mechanische Stiftzuhaltungen auf und können mittels eines mechanischen Schlüssels entsperrt werden, um mittels eines Schließbartes ein Türschloss zu ver- oder entriegeln.Conventional lock cylinders have mechanical pin tumblers and can be unlocked by means of a mechanical key to lock or unlock a door lock by means of a lock bit.

Elektronische Schließzylinder weisen in der Regel eine Steuereinrichtung elektronischer Art auf. Sobald ein Identifikationscode von der elektronischen Steuereinrichtung akzeptiert wird, wird eine Kupplung angesteuert, um das Schließglied mit dem Betätigungsglied zu verbinden, um so zu ermöglichen, dass ein Benutzer mittels des Betätigungsgliedes das Schloss ver- oder entriegeln kann.Electronic lock cylinders usually have a control device of electronic type. Once an identification code is accepted by the electronic control device, a clutch is actuated to connect the closure member to the actuator so as to allow a User can lock or unlock the lock by means of the actuator.

Zum Ansteuern der Kupplung kann innerhalb des Schließzylinders beispielsweise ein geeigneter Antrieb, beispielsweise ein Motor, vorgesehen sein.For driving the clutch can be provided within the lock cylinder, for example, a suitable drive, such as a motor.

Dabei kann die Prüfung der Zutrittsberechtigung mittels eines mobilen Transponders (Identträgers) erfolgen, in dem für die Überprüfung der Zutrittsberechtigung relevante Daten (Identifikationscode bzw. Zutrittberechtigungscode) in elektronischer Form gespeichert sind.In this case, the access authorization can be checked by means of a mobile transponder (identification carrier) in which data relevant for checking the access authorization (identification code or access authorization code) are stored in electronic form.

In manchen Systemen ist vorgesehen, dass der Schließzylinder mit einem Spannungsversorgungsnetz verbunden ist. Dies erfordert jedoch eine relativ aufwändige Verkablung. Dies gilt insbesondere dann, wenn vorgesehen ist, einen vorhandenen herkömmlichen mechanischen Schließzylinder durch einen elektronischen Schließzylinder zu ersetzen.In some systems it is provided that the lock cylinder is connected to a power supply network. However, this requires a relatively complex cabling. This is especially true when it is intended to replace an existing conventional mechanical lock cylinder with an electronic lock cylinder.

Es ist daher auch bekannt, elektronische Schließzylinder mit einer eigenen Energieversorung (Energiespeicher in Form einer Batterie oder eines Akkumulators) auszustatten. Solche elektronischen Schließzylinder eignen sich auch zur Nachrüstung und sind für eine einfache Integration in bestehende Schließanlagen geeignet.It is therefore also known to equip electronic lock cylinder with its own energy supply (energy storage in the form of a battery or a rechargeable battery). Such electronic lock cylinders are also suitable for retrofitting and are suitable for easy integration into existing locking systems.

Bei solchen elektromechanischen Schließeinrichtungen (elektronischen Schließzylindern) wird zum Entsperren häufig ein mechanisches Schließglied (zum Beispiel ein Schließbart) mit einem Betätigungsglied (Handhabe, vorzugsweise ein Knauf oder ähnliches) gekuppelt. Der eigentliche Ver- oder Entriegelungsvorgang erfolgt dann durch Betätigen des Betätigungsgliedes. Hierdurch wird Energie eingespart.In such electromechanical locking devices (electronic lock cylinders) is often to unlock a mechanical closure member (for example, a cam) with an actuator (handle, preferably a knob or the like) coupled. The actual locking or unlocking then takes place by pressing the actuator. This saves energy.

Eine weitere Maßnahme, um die Energieaufnahme möglichst gering zu halten, besteht darin, den elektronischen Teil der elektromechanischen Schließeinrichtung bei Nichtbenutzung in einen inaktiven Modus zu versetzen (Schlafmodus). In dem inaktiven Modus befindet sich die Elektronik des Schließzylinders in einem Zustand, in dem die autarke Energieversorgung möglichst wenig, im Idealfall gar nicht, belastet wird.Another measure to minimize the power consumption is to put the electronic part of the electromechanical lock when not in use in an inactive mode (sleep mode). In the inactive mode, the electronics of the lock cylinder is in a state in which the self-sufficient energy supply as little as possible, ideally not at all, is charged.

Nichtsdestotrotz wird bei derartigen elektronischen Schließzylindern zumindest bei dem Einkuppelvorgang eine nicht unerhebliche Energie verbraucht, so dass derartige Schließzylinder allenfalls wartungsarm, nicht aber weitgehend wartungsfrei ausgebildet werden können.Nevertheless, a considerable energy is consumed in such electronic locking cylinders at least during the coupling process, so that such lock cylinder can be formed at most low maintenance, but not largely maintenance-free.

Das Dokument US 6 370 928 B1 zeigt einen elektromechanisch betriebenen Schließzylinder mit einem Generator zum Erzeugen von elektrischer Energie zum Betreiben eines Schaltkreises.The document US Pat. No. 6,370,928 B1 shows an electromechanically operated lock cylinder with a generator for generating electrical energy for operating a circuit.

Es ist die Aufgabe der vorliegenden Erfindung, einen verbesserten Schließzylinder sowie ein verbessertes Schließverfahren anzugeben.It is the object of the present invention to provide an improved lock cylinder and an improved closure method.

Diese Aufgabe wird bei dem eingangs genannten Schließzylinder dadurch gelöst, dass das Betätigungsglied ein Knauf ist, in dem der als elektrischer Generator ausgebildete elektromechanische Wandler angeordnet ist, der eine Betätigung des Knaufes in elektrische Energie umsetzt, die dazu verwendet wird, die drahtlose Kommunikation mit dem Transponder und/oder bei Empfang eines gültigen Identifikationssignals das Einkuppeln der Kupplung zu unterstützen.This object is achieved with the lock cylinder mentioned above in that the actuator is a knob in which the constructed as an electrical generator electromechanical transducer is arranged, which converts an operation of the knob into electrical energy, which is used to wireless communication with the Transponder and / or on receipt of a valid identification signal to assist the coupling of the clutch.

Die obige Aufgabe wird ferner gelöst durch ein Verfahren zum Durchführen eines Schließvorganges eines Schlosses, insbesondere einer Tür, mit den Schritten:

  • Betätigen eines Knaufes eines Schließzylinders des Schlosses, wobei hierbei mechanische Energie übertragen wird und wobei ein als elektrischen Generator ausgebildeter elektromechanischer Wandler in dem Knauf angeordnet ist, der eine Betätigung des Knaufes in elektrische Energie umsetzt;
  • Umwandeln der auf den Knauf übertragenen mechanischen Energie in elektrische Energie;
  • Versorgen einer Steuereinrichtung mit der elektrischen Energie, wobei die Steuereinrichtung eine drahtlose Kommunikation mit einem Transponder aufbaut;
  • Empfangen eines Codes von dem Transponder in der Steuereinrichtung und Überprüfen desselben auf Gültigkeit; und
  • Betätigen einer Kupplung zum Verbinden des Knaufes mit einem Schließglied, sofern der empfangene Identifikationscode gültig ist.
The above object is further achieved by a method for performing a closing operation of a lock, in particular a door, with the steps:
  • Actuating a knob of a lock cylinder of the lock, in which case mechanical energy is transmitted and wherein an electrical generator designed as an electromechanical transducer is arranged in the knob, which converts an operation of the knob into electrical energy;
  • Converting the mechanical energy transferred to the knob into electrical energy;
  • Supplying a control device with the electrical energy, wherein the control device establishes a wireless communication with a transponder;
  • Receiving a code from the transponder in the controller and checking it for validity; and
  • Actuating a coupling for connecting the knob with a closing member, if the received identification code is valid.

In einem mechatronischen Schließzylinder sind eine Zutrittskontrollelektronik und ein elektromechanischer (eigentlich "mechano-elektrischer") Energiewandler vorgesehen. Der Energiewandler wird mittels der Betätigung einer Handhabe (Betätigungsglied) betrieben und erzeugt Energie. Mit der erzeugten Energie wird die Elektronik z.B. versorgt und zumindest unterstützend betrieben. Das Bereitstellen der Energie ist gleichzeitig der Auslöser eines Kommunikationsaufbaus zu einem ID-Geber (Transponder). Dieser wird in geeigneter Weise durch das Signal der Schließzylinderelektronik aktiviert, um mit der Steuerelektronik des Schließzylinders zu kommunizieren. Ist der ID-Geber berechtigt, wird zum Beispiel ein Kupplungselement angesteuert, welches den Schließbart des Zylinders freigibt bzw. einkuppelt, so dass der Riegel oder die Falle des Schlosses betätigt werden kann.In a mechatronic lock cylinder an access control electronics and an electromechanical (actually "mechano-electrical") energy converter are provided. The energy converter is operated by the operation of a handle (actuator) and generates energy. With the generated energy, the electronics, for example, supplied and operated at least supportive. The provision of energy is also the trigger of a communication setup to an ID transmitter (transponder). This is suitably indicated by the signal the lock cylinder electronics activated to communicate with the control electronics of the lock cylinder. If the ID transmitter is authorized, for example, a coupling element is activated, which releases or engages the cam of the cylinder, so that the bolt or the latch of the lock can be actuated.

Es ist auch möglich, dass die von dem Energiewandler bereitgestellte elektrische Energie nur dazu verwendet wird, eine Steuereinrichtung aus einem Schlafmodus zu wecken, um so durch die mechanische Betätigung eine Unterstützung zu leisten. Dabei wird die Steuereinrichtung nach dem Wecken durch andere Energiequellen gespeist (z.B. Batterie, Netz, etc.).It is also possible that the electrical energy provided by the energy converter is only used to wake a control device out of a sleep mode so as to provide support by the mechanical actuation. In this case, the control device is fed after awakening by other energy sources (for example battery, mains, etc.).

Die bei einem Drehen des Betätigungsgliedes erzeugte elektrische Energie kann dazu verwendet werden, um die Funkverbindung mit dem Transponder aufzubauen. Dabei kann es bei einem aktiven, batteriegespeisten Transponder möglich sein, diesen mittels eines "burst"-Signals aus einem Schlafmodus zu wecken, so dass dieser dann seinen Identifikationscode sendet. Der Code wird empfangen (vorzugsweise immer noch gestützt durch die durch das Drehen des Knaufes erzeugte Energie), und auch die Kupplung zum Verbinden des Knaufes mit einem Riegel oder einem sonstigen Sperrglied wird vorzugsweise betätigt auf der Grundlage der durch das Drehen des Knaufes erzeugten Energie.The electrical energy generated upon rotation of the actuator may be used to establish the radio connection with the transponder. It may be possible for an active, battery-powered transponder to wake this by means of a "burst" signal from a sleep mode, so that this then sends its identification code. The code is received (preferably still supported by the energy generated by the turning of the knob), and also the coupling for connecting the knob to a latch or other locking member is preferably actuated based on the energy generated by the rotation of the knob.

Vorzugsweise bedeutet das erfindungsgemäße Verfahren für den Benutzer, dass er lediglich das Betätigungsglied (den Knauf) dreht, bis die Tür geöffnet ist. Weiterhin bedeutet dies: die Abläufe der Energiewandlung, der Authentisierung und des Schließens selbst können miteinander verschmelzen, so dass sie wie ein Vorgang wirken und die Handhabung denkbar einfach ist, als würde keine Authentisierung stattfinden.Preferably, the inventive method means to the user that he only rotates the actuator (the knob) until the door is opened. Furthermore, this means: the processes of energy conversion, authentication and closing itself can merge together so that they how a process works and the handling is very simple, as if no authentication took place.

Demzufolge ist es möglich, den Schließzylinder im Idealfall vollkommen batterielos, also ohne eigene Energiequelle, auszugestalten. Die Energieversorgung erfolgt allein durch das Drehen des Knaufes (oder eine sonstige mechanische Bewegung an einem hierzu geeigneten Glied, beispielsweise Herunterdrücken eines Hebels, Zusammendrücken von zwei Hebeln o.ä.).Consequently, it is possible, the lock cylinder ideally completely batteryless, so without own power source to design. The power is supplied solely by turning the knob (or other mechanical movement of a suitable member, for example, pushing down a lever, squeezing two levers, etc.).

Selbst dann, wenn auf eine zusätzliche Energiequelle (wie eine Batterieversorgung oder ein Akkumulator) nicht vollständig verzichtet werden kann, kann diese Energiequelle entweder sehr klein oder besonders langlebig sein, da durch das Drehen des Knaufes Zusatzenergie erzeugt wird.Even if an additional energy source (such as a battery or an accumulator) can not be completely dispensed with, this energy source can be either very small or particularly durable, since additional energy is generated by turning the knob.

Insbesondere ist es möglich, dass bei Verwendung einer wiederaufladbaren Energiequelle, insbesondere eines Akkumulators und/oder eines Kondensators, vorgesehen ist, dass durch Betätigung des Betätigungsgliedes die wiederaufladbare Energiequelle aufgeladen wird.In particular, it is possible that when using a rechargeable power source, in particular an accumulator and / or a capacitor, it is provided that the rechargeable energy source is charged by actuation of the actuator.

Ferner kann der Transponder, der in Verbindung mit einem solchen Schließzylinder verwendet wird, ein passiver Transponder oder ein aktiver Transponder sein. Passive Transponder sind an sich bekannt. Ein passiver Transponder weist keine eigene Energieversorgung auf.Further, the transponder used in connection with such a lock cylinder may be a passive transponder or an active transponder. Passive transponders are known per se. A passive transponder does not have its own power supply.

Der elektromechanische Wandler ist als elektrische Maschine (Generator) ausgebildet, bspw. als Kombination aus Permanentmagnet(en) mit einer oder mehreren Induktionsspulen, als Piezo-Wandler o.ä. Bei Verwendung eines Generators kann beispielsweise auch ein Getriebe o.ä. vorgesehen sein, um eine Drehzahloptimierung zum Antrieb des Generators zu erzielen.The electromechanical transducer is designed as an electric machine (generator), for example as a combination of permanent magnet (s) with one or more induction coils, as a piezo-converter etc. When using a generator, for example, a gear o.ä. be provided to achieve a speed optimization for driving the generator.

Im Fall eines passiven Transponders wird auch der passive Transponder vorzugsweise zumindest teilweise durch die Energie versorgt, die durch das Betätigen des Betätigungsgliedes erzeugt wird.In the case of a passive transponder also the passive transponder is preferably at least partially powered by the energy generated by the actuation of the actuator.

Alternativ kann der Transponder ein aktiver Transponder sein, also ein batteriegestützter Transponder, der jedoch vorzugsweise in der Regel in einem Schlafmodus ist, so dass die Batterie nur im Schließfall belastet wird. Dann kann die Batterie mehrere Jahre halten.Alternatively, the transponder can be an active transponder, that is to say a battery-supported transponder which, however, is preferably in a sleep mode as a rule, so that the battery is only loaded in the event of a lock. Then the battery can last for several years.

Bei dem erfindungsgemäßen Verfahren ist es gemäß einer alternativen Ausgestaltung bevorzugt, wenn die durch Betätigen des Betätigungsgliedes erzeugte elektrische Energie unmittelbar zum Betrieb der Steuereinrichtung und/oder der Kupplung verwendet wird.In the method according to the invention, it is preferred according to an alternative embodiment, when the electrical energy generated by operating the actuator is used directly for the operation of the control device and / or the clutch.

Alternativ ist es auch möglich, die durch Betätigen des Betätigungsgliedes erzeugte elektrische Energie zunächst zumindest teilweise in einem wieder aufladbaren elektrischen Energiespeicher, wie einem Akkumulator und/oder einem Kondensator, zu speichern.Alternatively, it is also possible to initially store the electrical energy generated by actuating the actuating member at least partially in a rechargeable electrical energy store, such as an accumulator and / or a capacitor.

In Figur 1 ist eine Schließanlage generell mit 10 bezeichnet.In FIG. 1 is a locking system generally designated 10.

Die Schließanlage 10 ist für eine Tür 12 vorgesehen, die eine Außenseite A von einer Innenseite I trennt. Die Schließanlage 10 ermöglicht, dass Personen P zu der Innenseite I lediglich dann Zutritt haben, wenn sie hierzu berechtigt sind.The locking system 10 is provided for a door 12 which separates an outer side A from an inner side I. The locking system 10 allows persons P to the inside I only have access if they are entitled to do so.

Die Schließanlage 10 weist einen Schließzylinder 20 auf, der beispielsweise als Profilzylinder ausgebildet sein kann.The locking system 10 has a lock cylinder 20, which may be formed for example as a profile cylinder.

Bei dem Schließzylinder 20 handelt es sich um einen sogenannten elektronischen Schließzylinder. Der Schließzylinder 20 ist bei der vorliegenden Ausführungsform unabhängig von einem Spannungsversorgungsnetz. Er weist ferner keine eigene Energieversorgung auf. Alternativ ist es möglich, dass der Schließzylinder 20 eine wiederaufladbare Energiequelle, wie einen Akkumulator und/oder einen Kondensator, aufweist. Schließlich ist es auch möglich, dass der Schließzylinder 20 eine nicht wiederaufladbare Batterie oder Ähnliches aufweist.The lock cylinder 20 is a so-called electronic lock cylinder. The lock cylinder 20 is independent of a power supply network in the present embodiment. He also has no own energy supply. Alternatively, it is possible that the lock cylinder 20 has a rechargeable power source, such as an accumulator and / or a capacitor. Finally, it is also possible that the lock cylinder 20 has a non-rechargeable battery or the like.

Die Person P trägt zu ihrer Identifikation und zur Feststellung, ob sie zum Zutritt zu dem Innenraum I berechtigt ist, einen Transponder 22.The person P contributes to their identification and to determine whether they are entitled to access to the interior I, a transponder 22nd

An der Tür 12 sind ferner ein äußerer Knauf 24 und ein innerer Knauf 26 vorgesehen, die jeweils Betätigungsglieder bilden.On the door 12, an outer knob 24 and an inner knob 26 are further provided, each forming actuators.

Der Schließzylinder 20 weist ferner in an sich herkömmlicher Ausbildung ein Schließglied in Form eines Schließbartes 28 auf. Der Schließbart 28 betätigt in nicht näher dargestellter Weise einen Schließriegel eines Schlosses der Tür 12.The lock cylinder 20 also has a locking member in the form of a locking bit 28 in a conventional configuration. The cam 28 actuates in a manner not shown a locking latch of a lock of the door 12th

In einem Normalzustand ist der Schließbart 28 zumindest von dem äußeren Knauf 24 entkoppelt. Eine Person P, die in dem Normalzustand an dem äußeren Knauf 24 drehen würde, könnte demzufolge das Schloss der Tür 12 weder ver- noch entriegeln.In a normal state, the lock bit 28 is decoupled at least from the outer knob 24. As a result, a person P who would turn the outer knob 24 in the normal condition could not lock or unlock the door 12.

Der Schließzylinder 20 weist zum einen Mittel auf, um mit dem Transponder 22 der Person P in Kommunikation (zum Beispiel Funkkontakt) zu treten, und weist ferner eine nicht näher dargestellte Kupplung auf, die dazu ausgelegt ist, den äußeren Knauf 24 mit dem Schließbart 28 zu kuppeln.The lock cylinder 20 has, on the one hand, means for communicating (for example radio contact) with the transponder 22 of the person P, and furthermore has a coupling, not shown, which is designed to connect the outer knob 24 with the lock bit 28 to couple.

Ferner weist der Schließzylinder 20 eine nicht näher dargestellte Steuereinrichtung auf, die das Ein- und Auskuppeln der Kupplung sowie die Kommunikation mit dem Transponder 22 steuert und koordiniert.Furthermore, the lock cylinder 20 has a control device, not shown, which controls the coupling and disengagement of the clutch and the communication with the transponder 22 and coordinates.

Die Energieversorgung für die Steuereinrichtung sowie die Kupplung zum Kuppeln von äußerem Knauf 24 und Schließbart 28 erfolgt bei der vorliegenden Ausführungsform folgendermaßen: die Person P, die Einlass zu dem Innenraum I begehrt, übt auf den äußeren Knauf 24 eine Betätigungskraft 30 aus. Die hierdurch auf den Knauf 24 ausgeübte mechanische Energie wird mittels eines nicht näher dargestellten Wandlers in elektrische Energie umgewandelt, die die Steuereinrichtung und/oder die Kupplung speist.The power supply for the control device and the clutch for coupling the outer knob 24 and the lock bit 28 are as follows in the present embodiment: the person P who desires entrance to the inner space I exerts an actuating force 30 on the outer knob 24. The thereby exerted on the knob 24 mechanical energy is converted by means of a converter not shown in electrical energy, which feeds the control device and / or the clutch.

Obgleich es zwar theoretisch möglich erscheint, dass die Energieversorgung des Schließzylinders 20 ausschließlich aus der Betätigungskraft 30 der Person P abgeleitet wird, ist es in der Praxis in der Regel so, dass die Betätigungskraft 30 lediglich einen Beitrag, vorzugsweise einen überwiegenden Beitrag, zu der elektrischen Energieversorgung des Schließzylinders 20 beiträgt. In diesem Fall kann eine Batterie und/oder ein wiederaufladbarer Energiespeicher (wie ein Akkumulator und/oder ein Kondensator) vorgesehen sein, um die restlich benötigte Energie aufzubringen.Although it appears theoretically possible that the power supply of the lock cylinder 20 is derived solely from the actuation force 30 of the person P, in practice it is usually so that the actuating force 30 only a contribution, preferably a major contribution to the electrical power supply of the lock cylinder 20 contributes. In this case, a battery and / or a rechargeable energy storage (such as an accumulator and / or a capacitor) may be provided to apply the remaining energy required.

Es ist auch möglich, dass die Steuereinrichtung des Schließzylinders 20 sich in einem "Schlafmodus" befindet und durch die elektrische Energie, die aus der Betätigungskraft 30 abgeleitet wird, zunächst geweckt wird, um dann eine Abfrageprozedur nach autorisierten Transpondern 22 durchzuführen.It is also possible that the control means of the lock cylinder 20 is in a "sleep mode" and is first awakened by the electrical energy derived from the actuation force 30 to then perform an interrogation procedure for authorized transponders 22.

Eine solche Abfrageprozedur erfolgt folgendermaßen. Es wird zunächst, wie es schematisch bei 32 angedeutet ist, eine drahtlose Verbindung (zum Beispiel Funkverbindung) 32 zu dem Transponder 22 eingerichtet. Sofern es sich bei dem Transponder 22 um einen aktiven Transponder handelt, wird dieser zunächst durch das Abfragesignal "geweckt", der Transponder 22 sendet daraufhin den gespeicherten Identifikationscode zu dem Schließzylinder 20. Dort findet in der Steuereinrichtung ein Vergleich statt, ob der Identifikationscode autorisiert ist. Sofern dies der Fall ist, initiiert die Steuereinrichtung das Einkuppeln der Kupplung zum Verbinden des äußeren Knaufes 24 und des Schließbartes 28. Die Person P kann dann im eingekuppelten Zustand die Tür 12 entriegeln, um den Innenraum I zu gelangen.Such a polling procedure is done as follows. Initially, as indicated schematically at 32, a wireless connection (eg, radio link) 32 to the transponder 22 is established. If the transponder 22 is an active transponder, it is first "awakened" by the interrogation signal, the transponder 22 then sends the stored identification code to the locking cylinder 20. There, a comparison takes place in the control device as to whether the identification code is authorized , If this is the case, the control device initiates the engagement of the clutch for connecting the outer knob 24 and the lock bit 28. The person P can then unlock the door 12 in the engaged state to reach the inner space I.

Nach einer gewissen Zeit kuppelt die Kupplung wieder aus und die Steuereinrichtung wird wieder in einen "Schlafmodus" versetzt.After a certain time, the clutch disengages again and the control device is put back into a "sleep mode".

In der Praxis können das Betätigen des äußeren Knaufes 24, das Wecken der Steuereinrichtung, das Einrichten der drahtlosen Verbindung 32, das Überprüfen der Zugangsberechtigung in der Steuereinrichtung und das Schließen der Kupplung zeitlich unmittelbar aufeinander folgen, so dass für die Person P diese Vorgänge mehr oder weniger zeitlich verschmelzen. Mit anderen Worten ist es hierbei möglich, dass die Person P zum Zwecke des Erlangens eines Zutritts des Innenraums I lediglich den äußeren Knauf 24 betätigt (beispielsweise dreht). Während dieser Drehung wird die mechanische Energie in elektrische Energie gewandelt und die Autorisierungsprozedur findet statt, und noch während der Benutzer den äußeren Knauf 24 betätigt, wird die Kupplung eingekuppelt, so dass die weitere Betätigung zu einer Entriegelung des Schlosses der Tür 12 führt. Die Person P kann somit die Tür 12 quasi mit einem Handgriff öffnen.In practice, the operation of the outer knob 24, the awakening of the control device, the setting up of the wireless connection 32, the checking of the access authorization in the control device and the closing of the clutch can follow one another directly in time, so that for the person P these processes more or less time merge. In other words, in this case, it is possible for the person P to operate (eg, rotate) only the outer knob 24 for the purpose of obtaining an entrance of the inner space I. During this rotation, the mechanical energy is converted to electrical energy and the authorization procedure takes place, and while the user operates the outer knob 24, the clutch is engaged so that further actuation results in unlocking the lock of the door 12. The person P can thus open the door 12 virtually with a handle.

Der elektromechanische Energiewandler, der die Betätigungskraft 30 und die von der Person P aufgewendete Energie in elektrische Energie umwandelt, kann beispielsweise eine elektrische Maschine (Generator) sein, es kann sich auch um eine Kombination aus Permanentmagnet(en) mit einer oder mehreren Induktionsspulen handeln, der Wandler kann als Piezo-Wandler oder Ähnliches ausgebildet sein etc. Ferner kann zur Erlangung einer optimalen Energiewandlung ein Übersetzungsgetriebe mit dem Energiewandler, insbesondere dem elektrischen Generator, gekoppelt sein.The electromechanical energy converter, which converts the actuating force 30 and the energy expended by the person P into electrical energy, may for example be an electric machine (generator), it may also be a combination of permanent magnet (s) with one or more induction coils, the converter can be designed as a piezo-converter or the like, etc. Furthermore, in order to obtain an optimal energy conversion, a transmission gear can be coupled to the energy converter, in particular the electric generator.

Die folgenden Ausführungsformen von Schließzylindern gemäß den Figuren 2 bis 4 basieren sämtlich auf der oben in Bezug auf Figur 1 beschriebenen Ausführungsform. Gleiche Elemente sind daher mit gleichen Bezugsziffern versehen. Im Folgenden werden lediglich die jeweiligen Unterschiede zu der Ausführungsform der Figur 1 erläutert.The following embodiments of lock cylinders according to the FIGS. 2 to 4 are all based on the above FIG. 1 described embodiment. The same elements are therefore provided with the same reference numerals. The following will be only the respective differences from the embodiment of the FIG. 1 explained.

In Figur 2 ist als Schließzylinder ein Profilzylinder 20 mit einem äußeren Knauf 24 und einem inneren Knauf 26 dargestellt. Ferner ist in Figur 2 in schematischer Form die Kupplung 34 zum Verbinden bzw. Trennen von äußerem Knauf 24 und Schließbart 28 als Element im Inneren des Zylindergehäuses angedeutet.In FIG. 2 is shown as a lock cylinder, a profile cylinder 20 with an outer knob 24 and an inner knob 26. Furthermore, in FIG. 2 schematically indicated the coupling 34 for connecting or disconnecting the outer knob 24 and cam 28 as an element in the interior of the cylinder housing.

Figur 3 zeigt eine Ausführungsform eines erfindungsgemäßen Schließzylinders in schematischer Form. Der Schließzylinder 20 weist ein Betätigungsglied 40 (erfindungsgemäß einen Knauf, beispielsweise den äußeren Knauf 24) auf, das über die Kupplung 34 mit dem Schließglied 42 verbindbar ist. FIG. 3 shows an embodiment of a lock cylinder according to the invention in a schematic form. The lock cylinder 20 has an actuating member 40 (according to the invention a knob, for example, the outer knob 24), which is connectable via the coupling 34 with the closing member 42.

Das Betätigungsglied 40 ist ferner mit einem elektromechanischen Wandler 44 verbunden, der die Betätigungskraft 30 in elektrische Energie umwandelt und einer Steuereinrichtung 46 zuführt. Die Steuereinrichtung 46 ist mit einer Antenne 48 verbunden, über die die drahtlose Verbindung zwischen der Steuereinrichtung 46 und dem Transponder 22 erfolgt.The actuator 40 is further connected to an electromechanical transducer 44 which converts the actuating force 30 into electrical energy and supplies it to a control device 46. The control device 46 is connected to an antenna 48, via which the wireless connection between the control device 46 and the transponder 22 takes place.

Bei 50 ist ferner schematisch ein Aktuator angedeutet, den die Steuereinrichtung 46 ansteuert, um die Kupplung 34 zu öffnen bzw. zu trennen. Es ist auch möglich, dass die Kupplung 34 selbsttätig öffnend ist (beispielsweise mittels einer mechanischen Vorspannfeder), so dass der Aktuator 50 lediglich einseitig wirkend ausgebildet sein muss.At 50, an actuator is also schematically indicated, which controls the control device 46 to open the clutch 34 and to separate. It is also possible that the clutch 34 is self-opening (for example by means of a mechanical biasing spring), so that the actuator 50 must be formed only one-sided acting.

Statt einer Kupplung 34 kann auch ein Stellglied, welches das Kuppeln durch seine Stellung zulässt oder verhindert, verwendet werden.Instead of a clutch 34 may also be an actuator, which allows or prevents the coupling by its position, can be used.

Bei 52 ist eine optionale Energiequelle dargestellt. Im Idealfall reicht die Betätigungskraft 30 aus, um die Steuereinrichtung 46 während der Kommunikation mit dem Transponder 22 und zum Betätigen der Kupplung 34 mit elektrischer Leistung zu versorgen. Es ist jedoch auch möglich, dass ein zusätzlicher elektrischer Energiespeicher, wie eine Batterie, ein Akkumulater und/oder ein Kondensator, vorgesehen ist, so dass die Betätigungskraft 30 lediglich einen Teil der notwendigen elektrischen Leistung bereitstellen muss.At 52, an optional power source is shown. Ideally, the actuation force 30 is sufficient to supply the controller 46 with electrical power during communication with the transponder 22 and to actuate the clutch 34. However, it is also possible for an additional electrical energy store, such as a battery, an accumulator and / or a capacitor, to be provided, so that the actuation force 30 only has to provide a part of the necessary electrical power.

In Figur 4 ist eine schematische Konstruktion dargestellt, bei der der äußere Knauf 24 über eine durchgehende Welle bis in das Innere des inneren Knaufes 26 reicht. Diese Welle ist in Figur 4 mit 54 bezeichnet und ist als hohe Welle ausgebildet.In FIG. 4 a schematic construction is shown in which the outer knob 24 extends over a continuous shaft into the interior of the inner knob 26. This wave is in FIG. 4 designated 54 and is formed as a high wave.

Im Inneren des inneren Knaufes 26 ist die Steuereinrichtung 46 angeordnet. Die Antenne 48 ist im Inneren des äußeren Knaufes 24 angeordnet und durch die Hohlwelle 54 hindurch mittels einer elektrischen Leitung 56 mit der Steuereinrichtung 46 verbunden.Inside the inner knob 26, the control device 46 is arranged. The antenna 48 is disposed inside the outer knob 24 and connected through the hollow shaft 54 by means of an electrical line 56 to the controller 46.

Ferner ist dargestellt, dass der Schließbart 28 drehbar in Bezug auf die Hohlwelle 54 gelagert ist. Die Kupplung 34 ist schematisch als axial verschiebliches Element dargestellt (Pfeil in Richtung der Betätigung mittels Aktuator 50), obgleich natürlich auch eine radiale Kupplung möglich ist. Die Steuereinrichtung 46 ist mit der Kupplung 34 (bzw. dem Aktuator 50) über eine elektrische Leitung 58 verbunden. Über die elektrische Leitung 58 steuert die Steuereinrichtung 46 den Aktuator für die Kupplung 34 an.It is further shown that the cam 28 is rotatably supported with respect to the hollow shaft 54. The coupling 34 is shown schematically as an axially displaceable element (arrow in the direction of actuation by means of actuator 50), although of course a radial coupling is possible. The control device 46 is connected to the clutch 34 (or the actuator 50) via an electrical line 58. About the electrical Line 58 controls the controller 46 to the actuator for the clutch 34.

Der im Inneren des inneren Knaufes 26 angeordnete elektromechanische Wandler 44 weist ein erstes Glied auf, das mit der Hohlwelle 54 verbunden ist, und ein zweites Glied, dessen elektrischer Ausgang mit der Steuereinrichtung 46 verbunden ist.The arranged inside the inner knob 26 electromechanical transducer 44 has a first member which is connected to the hollow shaft 54, and a second member whose electrical output is connected to the control device 46.

Wie es schematisch bei 62 dargestellt ist, kann das erste Glied über einen Freilauf 62 mit der Hohlwelle 54 verbunden sein. Dabei kann dieses erste Glied auch als Schwungmasse (Schwungrad) ausgebildet sein, um die elektrische Energieversorgung möglichst lange aufrecht erhalten zu können.As schematically illustrated at 62, the first member may be connected via a freewheel 62 to the hollow shaft 54. In this case, this first member may also be designed as a flywheel (flywheel) in order to maintain the electrical power supply as long as possible.

Bei 60 ist ferner schematisch angedeutet, dass der innere Knauf 26 starr mit dem Schließbart 28 gekoppelt sein kann, so dass Personen von der Innenseite I aus die Tür 12 ohne Berechtigungsnachweis verriegeln bzw. entriegeln können.At 60 is further indicated schematically that the inner knob 26 may be rigidly coupled to the lock bit 28, so that persons from the inside I from the door 12 can lock or unlock without proof of entitlement.

In Figur 5 ist ein Flussdiagramm einer Ausführungsform des erfindungsgemäßen Verfahrens dargestellt.In FIG. 5 a flow chart of an embodiment of the method according to the invention is shown.

Der generelle Verfahrensablauf zum Durchführen eines Schließvorganges eines Schlosses beginnt im Schritt S2 (Startschritt).The general procedure for performing a closing operation of a lock starts in step S2 (starting step).

In einem darauffolgenden Schritt S6 erfolgt nach einer Betätigung des Betätigungsgliedes 24, 40 eine Energieumwandlung der Betätigungskraft 30 in elektrische Energie und damit eine elektrische Energieversorgung der Steuereinrichtung 46.In a subsequent step S6, after an actuation of the actuating member 24, 40, an energy conversion of the actuating force 30 into electrical energy and thus an electrical power supply of the control device 46 takes place.

Im Schritt S8 baut die Steuereinrichtung 46 eine drahtlose Kommunikationsverbindung zu dem Transponder 22 auf.In step S8, the controller 46 establishes a wireless communication link to the transponder 22.

Im Schritt S10 wird abgefragt, ob das empfangene Signal von dem Transponder 22 einen gültigen Identifikationscode enthält. Sofern dies der Fall ist (J im Schritt S10), steuert die Steuereinrichtung 46 im Schritt S12 den Aktuator 50 an, um die Kupplung 34 zu schließen.In step S10 it is queried whether the received signal from the transponder 22 contains a valid identification code. If so (J in step S10), the controller 46 in step S12 drives the actuator 50 to close the clutch 34.

Die Person P, die das Betätigungsglied 24, 40 betätigt hat, kann demzufolge durch Fortsetzen der Betätigung den Schließbart 28 betätigen und folglich das Schloss der Tür 12 ver- oder entriegeln.The person P who has actuated the actuator 24, 40 can thus actuate the cam 28 by continuing the operation and consequently lock or unlock the door 12.

Im Schritt S14 erfolgt nach Ablauf einer bestimmten Zeitdauer ein Auskuppeln der Kupplung 34, beispielsweise indem die Ansteuerung des Aktuators 50 beendet wird und die Kupplung 34 mittels eines Energiespeichers (zum Beispiel Feder) automatisch wieder in die ausgekuppelte Position übergeht.In step S14 after a certain period of time a disengagement of the clutch 34, for example by the actuation of the actuator 50 is terminated and the clutch 34 by means of an energy storage (for example spring) automatically returns to the disengaged position.

Im Schritt S16 ist die Ausführungsform des erfindungsgemäßen Verfahrens beendet bzw. das Verfahren beginnt erneut vor dem Schritt S4.In step S16, the embodiment of the method according to the invention is ended or the method restarts before step S4.

Die vorstehende Beschreibung gilt für einen einseitig schließbaren Schließzylinder. Bei einem beidseitig schließbaren Schließzylinder kann das Betätigungsglied der Außenknauf 24 oder der Innenknauf 26 sein.The above description applies to a lockable on one side lock cylinder. In a lockable on both sides lock cylinder, the actuator may be the outer knob 24 or the inner knob 26.
