Description

Die vorliegende Erfindung betrifft eine Schließvorrichtung für eine Tür mit aktivierbarer Privacy-Funktion zum Blockieren eines Zutritts von einer ersten Seite.The present invention relates to a locking device for a door with activatable privacy function for blocking access from a first page.

Aus dem Stand der Technik sind Schließvorrichtungen mit Privacy-Funktion beispielsweise bei Hotelzimmertüren bekannt. So kann ein sich im Hotelzimmer aufhaltender Gast, wenn er beispielsweise durch Personal nicht gestört werden möchte, den Zutritt zum Hotelzimmer von außen durch Einschalten der Privacy-Funktion blockieren.Closing devices with privacy function, for example in hotel room doors, are known from the prior art. For example, a guest staying in the hotel room, if he does not want to be disturbed by staff, can block access to the hotel room from the outside by switching on the privacy function.

Auf dem Markt erhältliche Lösungen weisen hierfür an der gesicherten Seite, beispielsweise dem Hotelzimmer, einen Schalter auf, dessen Signal mit einem Kabel auf die ungesicherte Seite geführt werden muss, beispielsweise zu einer Anzeige des Zustands der Privacy-Funktion für das Personal. Dies führt zu erhöhtem Montageaufwand, da ein Loch gebohrt und ein Kabel durchgeführt oder ein vorhandener Durchgang zur Kabeldurchführung genutzt werden muss. Hier besteht stets die Gefahr einer Beschädigung der Leitung. Eine solche Kabelverbindung zwischen gesicherter und ungesicherter Seite führt daher regelmäßig zu einem teuren Produkt. Ein zuverlässiger Betrieb ist nicht in hinreichendem Maße gewährleistet. Aus EP 0 193 537 A1 ist eine Schließvorrichtung für eine Tür umfassend eine mehrere Reedschalter aufweisende Steuerung an einer ersten Seite, und an der ersten Seite angeordnete Permanentmagneten bekannt, wobei die Permanentmagnete mit einer Türknaufwelle und einer Riegelwelle gekoppelt sind, so dass deren Stellung ermittelt werden kann. In JP 2008 261138 A ist eine Türverriegelung beschrieben. JP 2012 144950 A offenbart eine Sperrvorrichtung mit Anwesenheitserkennung.For this purpose, solutions available on the market have a switch on the secured side, for example the hotel room, whose signal has to be led with a cable to the unsecured side, for example to an indication of the status of the privacy function for the personnel. This leads to increased installation effort, since a hole must be drilled and carried out a cable or an existing passage must be used for cable entry. There is always the risk of damage to the line. Such a cable connection between the secured and unsecured side therefore regularly leads to an expensive product. Reliable operation is not guaranteed to a sufficient extent. Out EP 0 193 537 A1 is a door closing device comprising a multiple reed switch control on a first side, and on the first side arranged permanent magnet known, wherein the permanent magnets are coupled to a door knob shaft and a locking shaft, so that their position can be determined. In JP 2008 261138 A is described a door lock. JP 2012 144950 A discloses a locking device with presence detection.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Mitteln eine zuverlässige Privacy-Funktion an einer Schließvorrichtung zu ermöglichen.The present invention has for its object to provide a simple way of constructive means a reliable privacy function on a locking device.

Die vorliegende Erfindung löst die Aufgabe mit den Merkmalen des Anspruchs 1. Danach zeichnet sich die Schließvorrichtung aus durch eine einen Magnetfeldsensor aufweisende Steuerung an der ersten oder ungesicherten Seite, mindestens einen Dauermagneten an einer von der ersten Seite abgewandten zweiten oder gesicherten Seite, und ein sich von der ersten Seite bis zur zweiten Seite erstreckendes ferromagnetisches Befestigungselement, wobei der mindestens eine Dauermagnet mittels einer Handhabe zwischen einer die Privacy-Funktion aktivierenden Verriegelungsstellung und einer die Privacy-Funktion deaktivierenden Freigabestellung verlagerbar ist, wobei das Befestigungselement zur Übertragung des Magnetfelds des mindestens einen Dauermagneten auf den Magnetfeldsensor dient, so dass die Steuerung in Abhängigkeit von der Stellung des mindestens einen Dauermagneten ein Betätigen der Schließvorrichtung von der ersten Seite ermöglicht oder sperrt.The present invention achieves the object with the features of claim 1. Thereafter, the locking device is characterized by a control having a magnetic field sensor on the first or unsecured side, at least one permanent magnet on a second or secured side facing away from the first side, and a extending from the first side to the second side ferromagnetic fastening element, wherein the at least one permanent magnet is displaceable by means of a handle between a privacy function activating the locking position and the privacy function deactivating release position, wherein the fastening element for transmitting the magnetic field of the at least one permanent magnet is used on the magnetic field sensor, so that the controller in response to the position of the at least one permanent magnet allows actuation of the locking device from the first side or locks.

Eine solche Ausgestaltung hat den Vorteil, dass der Status der Privacy-Funktion ohne Kabelverbindung von der zweiten Seite (gesicherte Seite oder Türinnenseite) auf die erste Seite (ungesicherte Seite oder Türaußenseite) übertragen werden kann. Dies erfolgt nicht mittels einer aufwändigen Elektronik, sondern mittels mindestens eines Dauermagneten, dessen Magnetfeld über das ferromagnetische Befestigungselement auf einen Magnetfeldsensor übertragen wird. Die Anfertigung von Bohrungen und Kabeldurchführungen ist nicht erforderlich, da ein bereits vorhandenes Befestigungselement genutzt wird. Das Befestigungselement kann zur Befestigung der Schließvorrichtung an einer Tür dienen. Auf diese Weise ist mit einfachen konstruktiven Mitteln eine zuverlässige Übertragung der Privacy-Funktion geschaffen.Such an embodiment has the advantage that the status of the privacy function is transmitted without cable connection from the second side (secured side or door inner side) to the first side (unsecured side or outside of the door) can be. This is not done by means of a complex electronics, but by means of at least one permanent magnet whose magnetic field is transmitted via the ferromagnetic fastener to a magnetic field sensor. The preparation of holes and cable glands is not required because an existing fastener is used. The fastening element can serve for fastening the closing device to a door. In this way, a reliable transmission of the privacy function is created with simple structural means.

Das ferromagnetische Befestigungselement kann aus Stahl ausgebildet sein, je nach seinen ferromagnetischen Eigenschaften auch aus Edelstahl. Außerdem kann das Befestigungselement orthogonal zur Türblattebene oder Türflügelebene angeordnet sein.The ferromagnetic fastener may be formed of steel, depending on its ferromagnetic properties and stainless steel. In addition, the fastener may be arranged orthogonal to the door leaf level or door leaf level.

Mittels der Handhabe ist der mindestens eine Dauermagnet relativ zum Befestigungselement verlagerbar. Wird der Dauermagnet mit einem Pol dem Befestigungselement angenähert, detektiert der Magnetfeldsensor eine Feldänderung, wodurch ein Umschalten des Ausgangssignals des Magnetfeldsensors erfolgt. Hierdurch kann die Privacy-Funktion eingeschaltet werden. Ein Betätigen der Schließvorrichtung von der ersten Seite ist dann gesperrt. Bei Entfernen des Dauermagneten vom Befestigungselement detektiert der Magnetfeldsensor erneut eine Feldänderung, wodurch das Ausgangssignal des Magnetfeldsensors erneut umgeschaltet wird. Hiermit kann die Privacy-Funktion ausgeschaltet werden.By means of the handle, the at least one permanent magnet is displaceable relative to the fastening element. If the permanent magnet with a pole approximates the fastening element, the magnetic field sensor detects a field change, whereby a switching of the output signal of the magnetic field sensor takes place. This allows the privacy feature to be turned on. Actuation of the locking device from the first side is then locked. Upon removal of the permanent magnet from the fastener, the magnetic field sensor again detects a field change, whereby the output of the magnetic field sensor is switched again. This can be used to switch off the privacy function.

Es ist denkbar, dass die Schließvorrichtung ein Einsteckschloss aufweist, welches stirnseitig in eine Tasche eines Türflügels eingebaut werden kann.It is conceivable that the locking device has a mortise lock, which can be installed on the front side in a pocket of a door leaf.

In vorteilhafter Weise ist zur Türöffnung auf der ersten oder ungesicherten Seite eine mit der Steuerung zusammenwirkende Authentifizierungseinrichtung vorgesehen. Hierbei kann es sich insbesondere um einen RFID-Kartenleser handeln. Je nach Status der Privacy-Funktion (aktiviert oder deaktiviert) wird eine Betätigung der Schließvorrichtung durch die Authentifizierungseinrichtung ermöglicht oder blockiert. Anstelle einer vollständigen Blockierung ist denkbar, dass Karten oder Transponder mit unterschiedlichen Autorisierungsniveaus existieren, so dass bei Einschalten der Privacy-Funktion eine höher autorisierte Karte oder ein höher autorisierter Transponder zugelassen wird, Schlüssel niedriger Autorisierung jedoch blockiert werden. Somit kann beispielsweise ein Sicherheitsdienst auch bei aktivierter Privacy-Funktion Zutritt zu beispielsweise einem Hotelzimmer erhalten, nicht jedoch das Reinigungspersonal.Advantageously, an authentication device cooperating with the control is provided for the door opening on the first or unsecured side. This may in particular be an RFID card reader. Depending on the status of the privacy function (activated or deactivated), activation of the locking device is enabled or blocked by the authentication device. Instead of a complete blocking, it is conceivable that cards or transponders with different authorization levels exist, so that when the privacy function is activated, a higher authorized card or a higher authorized transponder is allowed, but lower authorization keys are blocked. Thus, for example, a security service even with activated privacy function access to, for example, a hotel room, but not the cleaning staff.

Zweckmäßigerweise kann eine mit der Steuerung zusammenwirkende Kupplungseinrichtung vorgesehen sein, welche zur Türöffnung einen Türdrücker oder Türknauf mit einem Schließelement oder einem Schlosseingerichte der Schließvorrichtung koppelt. Durch diese Kopplung kann durch Betätigung des Türdrückers oder Türknaufs ein Schließelement zurückgeschlossen und die betreffende Tür geöffnet werden. Das Schließelement kann als Fallenriegel oder Schließriegel ausgebildet sein. Mit anderen Worten kann die Schließvorrichtung ein Einsteckschloss mit integrierter Kupplungseinrichtung, insbesondere einen kuppelbaren Beschlag, aufweisen.
Zur Signalisierung des Zustandes der Privacy-Funktion (aktiviert oder deaktiviert) an Zutrittspersonen kann die Steuerung ein Anzeigeelement zur Anzeige des Status der Privacy-Funktion aufweisen. Hiermit werden Zutrittspersonen bei einem Zutrittsversuch über den Status der Privacy-Funktion informiert. Beispielsweise kann eine LED als Anzeigeelement dienen.
Appropriately, cooperating with the controller coupling device may be provided, which couples to the door opening a door handle or doorknob with a closing element or a Schlosseigerichte the closing device. Through this coupling can be closed by pressing the door handle or doorknob, a closing element and the relevant door to be opened. The closing element can be designed as a latch bolt or locking bolt. In other words, the locking device may have a mortise lock with integrated coupling device, in particular a detachable fitting.
For signaling the state of the privacy function (activated or deactivated) to access persons, the controller can have a display element for displaying the status of the privacy function. Hereby become access persons informed about the status of the privacy function during an access attempt. For example, an LED can serve as a display element.

Im Konkreten kann die Handhabe als Schlitten, Drehknauf, Schieber oder Taster ausgebildet sein. Mit diesen Mitteln ist ein Heranführen des mindestens einen Dauermagneten an das Befestigungselement ermöglicht.Concretely, the handle can be designed as a carriage, knob, slide or button. These means make it possible to bring the at least one permanent magnet to the fastening element.

In vorteilhafter Weise kann die Handhabe eine Anzeige aufweisen oder selbst als Anzeige dienen. Auf diese Weise wird der eine Privacy-Funktion einschaltenden Person, die sich auf der zweiten oder gesicherten Seite der Tür befindet, der Zustand der Privacy-Funktion signalisiert. Die Anzeige kann als Display, Textinformation oder dergleichen ausgebildet sein. Ebenso kann die Handhabe als Anzeige dienen, indem der Untergrund oder Hintergrund der Handhabe, beispielsweise das Türblatt, farblich unterlegt ist. Die Handhabe kann ein Hinweiselement, beispielsweise einen auf den farblichen Untergrund hinweisenden Pfeil, aufweisen.Advantageously, the handle can have an indication or even serve as a display. In this way, the person who activates a privacy function, which is located on the second or secure side of the door, is informed of the status of the privacy function. The display can be designed as a display, text information or the like. Likewise, the handle can serve as an indicator by the background or background of the handle, such as the door leaf, is highlighted in color. The handle may have a reference element, for example an arrow pointing to the colored background.

In Bezug auf die Positionierung des mindestens einen Dauermagneten ist von Vorteil, wenn dieser an oder innerhalb der Handhabe angeordnet und vorzugsweise von dieser umschlossen ist. Hiermit ist der mindestens eine Dauermagnet relativ zum Benutzer abgeschirmt, wodurch Beeinträchtigungen des Magnetfelds des Dauermagneten weitestgehend ausgeräumt sind. In Richtung des Befestigungselements sollte der mindestens eine Dauermagnet unabgeschirmt sein.With regard to the positioning of the at least one permanent magnet is advantageous if it is arranged on or within the handle and preferably surrounded by this. Hereby, the at least one permanent magnet is shielded relative to the user, whereby impairments of the magnetic field of the permanent magnet are largely eliminated. In the direction of the fastening element, the at least one permanent magnet should be unshielded.

Im Konkreten kann das Befestigungselement als eine die Schließvorrichtung an der Tür befestigende Montageschraube ausgebildet sein. Insbesondere kann die Montageschraube Beschläge der Schließvorrichtung an der Tür befestigen. Hinsichtlich ergonomischer Gesichtspunkte ist von Vorteil, wenn es sich dabei um die obere Montageschraube der Schließvorrichtung handelt, also um eine Montageschraube, die oberhalb eines Türdrückers oder eines Türknaufs angeordnet ist. Hiermit sind eine Handhabe auf der zweiten oder gesicherten Seite sowie ein ggf. vorhandenes Anzeigeelement oder eine Authentifizierungseinrichtung für eine Bedienperson gut zu erreichen und/oder gut einsehbar.Specifically, the fastener may be formed as a mounting screw attaching the locking device to the door. In particular, the mounting screw Fasten fittings of the locking device to the door. With regard to ergonomic aspects, it is advantageous if this is the upper mounting screw of the closing device, ie a mounting screw which is arranged above a door handle or a door knob. Hereby, a handle on the second or secured side as well as a possibly present display element or an authentication device for an operator are easy to reach and / or easy to see.

Um den konstruktiven Aufwand gering zu halten und Manipulationen möglichst zu vermeiden, ist es von Vorteil, wenn die Steuerung einen netzunabhängigen Energiespeicher aufweist. Hierfür kann eine Batterie oder ein Akkumulator eingesetzt werden. Dabei ist denkbar, dass die Steuerung, der Magnetfeldsensor sowie der Energiespeicher innerhalb eines Steuerungsgehäuses angeordnet und von diesem umschlossen sind. Somit sind diese Komponenten nach außen hin abgeschirmt und von Zugriffen durch Dritte geschützt.In order to keep the design effort low and to avoid manipulation as much as possible, it is advantageous if the controller has a network-independent energy storage. For this purpose, a battery or an accumulator can be used. It is conceivable that the controller, the magnetic field sensor and the energy storage are arranged within a control housing and enclosed by this. Thus, these components are shielded to the outside and protected from access by third parties.

In Bezug auf den Magnetfeldsensor ist denkbar, dass dieser als Hall-Sensor oder GMR-Sensor ausgebildet ist. Mit derartigen Sensoren kann das durch das Befestigungselement übertragene Magnetfeld des Dauermagneten detektiert werden. Um Einflüsse durch Remanenz der Befestigungsschraube auszuschließen, ist es von Vorteil, wenn der Magnetfeldsensor ein Sensor mit Latch-Verhalten ist. Dies bedeutet, dass ein Umschalten des Ausgangssignals des Sensors erst dann erfolgt, wenn ein entgegengesetzt gepoltes Feld einer definierten Mindestfeldstärke am Sensor detektiert wird. Dabei ist es in Bezug auf die Erfassungsgenauigkeit von Vorteil, wenn das Befestigungselement einer wechselnden Magnetisierung unterworfen ist, und zwar in Abhängigkeit von der Stellung des mindestens einen Dauermagneten.With respect to the magnetic field sensor is conceivable that this is designed as a Hall sensor or GMR sensor. With such sensors, the transmitted through the fastener magnetic field of the permanent magnet can be detected. To exclude influences by remanence of the fastening screw, it is advantageous if the magnetic field sensor is a sensor with latch behavior. This means that a switching of the output signal of the sensor takes place only when an oppositely poled field of a defined minimum field strength is detected at the sensor. It is advantageous in terms of detection accuracy, when the fastener is subjected to an alternating magnetization, depending on the position of the at least one permanent magnet.

Zweckmäßigerweise kann sich der Dauermagnet in der Verriegelungsstellung mit einem Pol in einer Flucht mit dem Befestigungselement befinden und in der Freigabestellung mit dem Gegenpol in einer Flucht mit dem Befestigungselement befinden. Auf diese Weise wird das Befestigungselement in den unterschiedlichen Stellungen des Dauermagneten durch entgegengesetzte Magnetfelder beaufschlagt, was eine Erfassung des Magnetfelds durch den Magnetfeldsensor begünstigt. Hierfür kann der Dauermagnet mittels der Handhabe entlang der Tür verlagert werden, beispielsweise mittels eines Schlittens.Conveniently, the permanent magnet may be in the locked position with a pole in alignment with the fastener and in the release position with the opposite pole in alignment with the fastener. In this way, the fastening element in the different positions of the permanent magnet is acted upon by opposite magnetic fields, which favors a detection of the magnetic field by the magnetic field sensor. For this purpose, the permanent magnet can be displaced by means of the handle along the door, for example by means of a carriage.

Alternativ hierzu kann sich der Dauermagnet in der Verriegelungsstellung mit einem Pol in einer Flucht mit dem Befestigungselement befinden und ein weiterer Dauermagnet kann sich in der Freigabestellung mit dem Gegenpol in einer Flucht mit dem Befestigungselement befinden. Auch hiermit wird das Befestigungselement in Verriegelungsstellung sowie in Freigabestellung durch entgegengesetzte Magnetfelder beaufschlagt. Hierfür können die Dauermagneten mittels der Handhabe relativ zur Tür verschwenkbar befestigt sein.Alternatively, the permanent magnet may be in the locked position with a pole in alignment with the fastener and another permanent magnet may be in the release position with the opposite pole in alignment with the fastener. Again, the fastener is acted upon in the locked position and in the release position by opposite magnetic fields. For this purpose, the permanent magnets may be pivotally mounted by means of the handle relative to the door.

Zweckmäßigerweise ist zur Überbrückung eines Luftspalts zwischen dem ferromagnetischen Befestigungselement und dem Magnetfeldsensor ein ferromagnetisches Element, insbesondere eine Schraube, angeordnet. Durch das ferromagnetische Element liegt infolge der Überbrückung des Luftspalts am Sensor ein stärkeres Feld an. Ist das ferromagnetische Element als Schraube ausgebildet, kann diese beispielsweise an einem die Steuerung umgebenden Gehäuse befestigt sein.Conveniently, a ferromagnetic element, in particular a screw, is arranged to bridge an air gap between the ferromagnetic fastening element and the magnetic field sensor. Due to the bridging of the air gap on the sensor, a stronger field is present due to the ferromagnetic element. If the ferromagnetic element is designed as a screw, it can for example be attached to a housing surrounding the control.

In vorteilhafter Weise ist die Steuerung derart ausgebildet, dass sich diese erst bei einem Zutrittsversuch, insbesondere einer versuchten Authentifizierung an der Authentifizierungseinrichtung, einschaltet. Dies ist hinsichtlich ökonomischer Gesichtspunkte von Vorteil, da somit ein geringer Energieverbrauch der Schließvorrichtung erzielt werden kann. Bei einem netzunabhängigen Energiespeicher, beispielsweise einem Akkumulator oder einer Batterie, kann somit eine lange Einsatzzeit erreicht werden.Advantageously, the controller is designed such that this only at a Access attempt, in particular an attempted authentication to the authentication device turns on. This is advantageous in terms of economic aspects, since thus a low energy consumption of the closing device can be achieved. In a network-independent energy storage, such as a battery or a battery, thus a long service life can be achieved.

Zweckmäßigerweise kann ein auf der zweiten Seite befindlicher Türdrücker, also ein auf der gesicherten Seite befindlicher Türdrücker, derart mit der Handhabe zusammenwirken, dass bei Betätigen des Türdrückers die Handhabe in die Freigabestellung verlagert wird. Somit wird beim Öffnen der Tür von der Innenseite die Privacy-Funktion automatisch deaktiviert, so dass ein erneutes Betreten des geschützten Bereichs, beispielsweise des Hotelzimmers, durch Authentifizieren an der Authentifizierungseinrichtung, ermöglicht ist.Conveniently, a door handle located on the second side, that is, a door handle located on the secured side, cooperate with the handle in such a manner that, upon actuation of the door handle, the handle is displaced into the release position. Thus, when the door is opened from the inside, the privacy function is automatically deactivated so that it is possible to re-enter the protected area, for example the hotel room, by authenticating to the authentication device.

Die Erfindung wird im Folgenden anhand der Figur näher erläutert. Es zeigt:

Figur 1
in einer schematischen Ansicht ein Ausführungsbeispiel einer Schließvorrichtung.
The invention will be explained in more detail below with reference to FIG. It shows:
FIG. 1
in a schematic view of an embodiment of a closing device.

Figur 1 zeigt eine Ausführungsform einer Schließvorrichtung 10 für eine Tür 12. Die Schließvorrichtung 10 weist eine aktivierbare Privacy-Funktion zum Blockieren eines Zutritts von einer ersten oder ungesicherten Seite 14 auf. FIG. 1 1 shows an embodiment of a closure device 10 for a door 12. The closure device 10 has an activatable privacy function for blocking access from a first or unsecured page 14.

Die Schließvorrichtung 10 umfasst eine einen Magnetfeldsensor 16 aufweisende Steuerung 18 an der ersten Seite 14. An einer von der ersten Seite 14 abgewandten zweiten oder gesicherten Seite 20 weist die Schließvorrichtung 10 einen Dauermagneten 22 und einen weiteren Dauermagneten 23 auf. Ein ferromagnetisches Befestigungselement 24 erstreckt sich von der ersten Seite 14 bis zur zweiten Seite 20.The locking device 10 comprises a magnetic field sensor 16 having a controller 18 on the first side 14. At a side facing away from the first side 14 second or secured side 20 has the Locking device 10 a permanent magnet 22 and another permanent magnet 23. A ferromagnetic fastener 24 extends from the first side 14 to the second side 20.

Der Dauermagnet 22 und der weitere Dauermagnet 23 sind mittels einer Handhabe 26 zwischen einer die Privacy-Funktion aktivierenden Verriegelungsstellung und einer die Privacy-Funktion deaktivierenden Freigabestellung verlagerbar. Die Handhabe 26 und damit auch die Dauermagneten 22, 23 sind relativ zur Tür 12 rotierbar, insbesondere um eine Achse 27.The permanent magnet 22 and the further permanent magnet 23 are displaceable by means of a handle 26 between a locking function activating the privacy function and a release position deactivating the privacy function. The handle 26 and thus also the permanent magnets 22, 23 are rotatable relative to the door 12, in particular about an axis 27th

Das Befestigungselement 24 dient zur Übertragung des Magnetfelds der Dauermagneten 22, 23 auf den Magnetfeldsensor 16. Die Steuerung 18 kann somit in Abhängigkeit von der Stellung der Dauermagneten 22, 23 ein Betätigen der Schließvorrichtung 10 von der ersten Seite 14 ermöglichen oder sperren. Ein ferromagnetisches Element 17, beispielsweise eine Schraube 17, überbrückt den Luftspalt zwischen dem Befestigungselement 24 und dem Magnetfeldsensor 16. Hiermit wird das magnetische Feld am Magnetfeldsensor 16 verstärkt.The fastening element 24 serves to transmit the magnetic field of the permanent magnets 22, 23 to the magnetic field sensor 16. The control 18 can thus enable or disable actuation of the closing device 10 from the first side 14 as a function of the position of the permanent magnets 22, 23. A ferromagnetic element 17, for example a screw 17, bridges the air gap between the fastening element 24 and the magnetic field sensor 16. This strengthens the magnetic field at the magnetic field sensor 16.

Zur Türöffnung ist auf der ersten Seite 14 eine mit der Steuerung 18 zusammenwirkende Authentifizierungseinrichtung 28 vorgesehen. Die Authentifizierungseinrichtung 28 ist als RFID-Kartenleser ausgebildet. Die Authentifizierungseinrichtung 28 ist mit der Steuerung 18 verbunden, beispielsweise über eine drahtgebundene Verbindung 29.For the door opening, an authentication device 28 cooperating with the controller 18 is provided on the first side 14. The authentication device 28 is designed as an RFID card reader. The authentication device 28 is connected to the controller 18, for example via a wired connection 29.

Die Kupplungseinrichtung 30 koppelt zur Türöffnung einen Türdrücker 32 mit einem Schließelement 34. Bei dem Schließelement 34 kann es sich um einen Fallenriegel oder einen Schließriegel handeln. Die Kupplungseinrichtung 30 ist über eine weitere, beispielsweise drahtgebundene, Verbindung 31 mit der Steuerung 18 verbunden.The coupling device 30 couples to the door opening a door handle 32 with a closing element 34. The closing element 34 may be a latch bolt or act a locking bolt. The coupling device 30 is connected via a further, for example, wired, connection 31 to the controller 18.

Die Schließvorrichtung 10 kann ein Einsteckschloss 36 aufweisen, welches stirnseitig in die Tür 12 eingebaut und mittels eines Stulps 38 an der Tür 12 befestigt wird.The locking device 10 may have a mortise lock 36, which is installed on the front side in the door 12 and fastened to the door 12 by means of a forend 38.

Die Steuerung 18 kann ein Anzeigeelement 40 zur Anzeige des Status der Privacy-Funktion aufweisen. Das Anzeigeelement 40 kann beispielsweise als LED ausgebildet sein.The controller 18 may include a display element 40 for indicating the status of the privacy function. The display element 40 may be formed, for example, as an LED.

Die Handhabe 26 ist im vorliegenden Ausführungsbeispiel als Drehknauf 42 ausgebildet, wobei der Drehknauf 42 relativ zur Tür 12 rotierbar ist.The handle 26 is formed in the present embodiment as a rotary knob 42, wherein the rotary knob 42 is rotatable relative to the door 12.

Die Handhabe 26 dient als Anzeige und ist farblich unterlegt. Damit kann der eine Privacy-Funktion einschaltenden Person der Status der Privacy-Funktion (aktiviert oder deaktiviert) signalisiert werden.
Die Dauermagneten 22, 23 sind an der Handhabe 26 angeordnet.
The handle 26 serves as a display and is highlighted in color. This allows the person who activates a privacy function to be signaled the status of the privacy function (activated or deactivated).
The permanent magnets 22, 23 are arranged on the handle 26.

Das Befestigungselement 24 ist als eine die Schließvorrichtung 10, insbesondere Beschläge 44, 46 der Schließvorrichtung 10 an der Tür 12 befestigende Montageschraube 48, ausgebildet.The fastening element 24 is designed as a mounting screw 48 which fixes the closing device 10, in particular fittings 44, 46 of the closing device 10 to the door 12.

Die Steuerung 18 weist einen Energiespeicher zur netzunabhängigen Energieversorgung, insbesondere eine Batterie oder einen Akkumulator auf (nicht dargestellt). Der Magnetfeldsensor 16 ist als Hall-Sensor mit Latch-Verhalten ausgebildet.The controller 18 has an energy storage for off-grid power supply, in particular a battery or an accumulator (not shown). The magnetic field sensor 16 is designed as a Hall sensor with latch behavior.

Der Dauermagnet 22 befindet sich in der Verriegelungsstellung mit einem Pol in einer Flucht mit dem Befestigungselement 24. In der Freigabestellung befindet sich der weitere Dauermagnet 23 mit dem Gegenpol in einer Flucht mit dem Befestigungselement 24. Dies erleichtert die Detektion der Schaltstellung der Dauermagneten 22, 23 und schließt Einflüsse durch Remanenz des Befestigungselements 24 weitestgehend aus.The permanent magnet 22 is in the locked position with a pole in alignment with the fastening element 24. In the release position, the further permanent magnet 23 is in alignment with the fastening element 24 with the opposite pole. This facilitates the detection of the switching position of the permanent magnets 22, 23 and excludes influences by remanence of the fastener 24 as far as possible.

Die Steuerung 18 ist derart ausgebildet, dass sich diese erst bei einem Zutrittsversuch, insbesondere einem Authentifizierungsversuch an der Authentifizierungseinrichtung 28, einschaltet. Dies sorgt für einen geringen Energieverbrauch.The controller 18 is designed such that it only turns on during an access attempt, in particular an authentication attempt on the authentication device 28. This ensures low energy consumption.

Ein auf der zweiten oder gesicherten Seite 20 befindlicher Türdrücker 50 wirkt derart mit der Handhabe 26 zusammen, dass bei Betätigen des Türdrückers 50 die Handhabe 26 in die Freigabestellung verlagert wird.A door handle 50 located on the second or secured side 20 interacts with the handle 26 in such a manner that, upon actuation of the door handle 50, the handle 26 is displaced into the release position.
