Zusammenfassung der ErfindungSummary of the Invention

Der Erfindung liegt die Aufgabe zugrunde, ein Schranktürschloss anzugeben, welches gegen ein händisch zu betätigendes Schranktürschloss austauschbar ist und eine verbesserte Funktionalität aufweist.The invention is based on the object of specifying a cabinet door lock which can be exchanged for a manually operated cabinet door lock and which has improved functionality.

Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The object is achieved by the invention specified in the claims.

In ihrer Gesamtheit besitzt das Schranktürschloss die nachfolgend aufgeführten konstruktiven und funktionellen Merkmale. Das Schranktürschloss besitzt ein Gehäuse. Das Gehäuse ist auf der zum Innenraum eines Schrankes weisenden Innenseite an einer Schranktür befestigbar. Es kann insbesondere gegen ein bereits dort vorhandenes Schrankschloss, welches nicht die technisch weiterbildenden Merkmale der Erfindung aufweist, ausgetauscht werden. Das Gehäuse beinhaltet einen Motor, der von einer elektronischen Schaltung angesteuert werden kann, oder eine Handhabe, die mit einem Riegelantrieb gekuppelt werden kann. Die elektronische Schaltung wirkt mit einer Codeeingabeeinrichtung zusammen. Über die Codeeingabeeinrichtung kann ein Öffnungscode eingegeben werden. Dies kann über eine Tastatur erfolgen. Die Codeeingabe kann aber auch durch in die Nähe halten eines Transponders erfolgen. Die Codeeingabeeinrichtung besitzt hierzu eine Kommunikationseinrichtung, die mit dem Transponder drahtlos kommuniziert. An den Transponder wird ein drahtloses Aufwecksignal gesendet, sodass der Transponder seine individuelle Kennung an die Codeeingabeeinrichtung sendet. Die Codeeingabeeinrichtung kann permanent oder intervallartig ein Prüfsignal erzeugen, welches ein elektromagnetisches Detektorfeld aufbaut, um zu prüfen, ob sich ein Transponder unmittelbar in der Nähe des Schranktürschlosses befindet. Dieses Signal wird mit sehr geringer Leistung erzeugt, sodass es keine Fernwirkung besitzt. Erst wenn das Vorhandensein eines Transponders in der unmittelbaren Nähe der Codeeingabeeinrichtung erfasst wird, wird ein leistungsstärkeres Aufwecksignal erzeugt, das den Transponder veranlasst, seine Kennung zu senden. Die Codeeingabeeinrichtung oder die elektronische Schaltung besitzen eine Schließberechtigungsprüfeinrichtung, mit der geprüft wird, ob der über die Tastatur oder die Transponder-Leseeinrichtung empfangene Öffnungscode eine Schließberechtigung besitzt. Diese Prüfung erfolgt aufgrund einer Aktivierung der elektronischen Schaltung, die entweder durch die PIN-Eingabe oder das Auslesen der Kennung eines Transponders erfolgt. Wird die Schließberechtigung des Öffnungscodes festgestellt, also bei einer schließberechtigten Aktivierung der elektronischen Schaltung, kann mit einem Betätigungsaggregat der Riegel zwischen zwei Riegelstellungen hin und her verlagert werden. Hierzu kann es vorgesehen sein, dass der Motor in Betrieb gesetzt, um den Riegel, der zwischen zwei Riegelstellungen hin und her verlagerbar ist, in die jeweils andere Riegelstellung zu verlagern. Es ist aber auch vorgesehen, dass eine Kupplung, die eine Betätigungshandhabe mit einem Riegelantrieb kuppelt von einer entkuppelten Stellung in eine gekuppelten Stellung gebracht wird, in der die Betätigung den Riegel verlagert. Der Riegel wird somit entweder in eine Öffnungsstellung gebracht, in der die Schranktür geöffnet werden kann, oder in eine Verriegelungsstellung, in der die Schranktür nicht geöffnet werden kann. Es ist eine Sende-Empfangseinrichtung vorgesehen, die von der optionalen Transponder-Leseeinrichtung funktionell getrennt ist. Diese, mit der elektronischen Schaltung zusammenwirkende Sende-Empfangseinrichtung dient zur drahtlosen Datenübertragung von zumindest Schließzustandsdaten an eine Zentraleinheit. Es ist vorgesehen, dass bei jeder Aktivierung der elektronischen Schaltung Schließzustandsdaten an die Zentraleinheit übertragen werden. Die Schließzustandsdaten beinhalten zumindest den Schließzustand des Schlosses vor bzw. nach der Codeeingabe und /oder den eingegebenen Code, also den PIN oder die individuelle Transponderkennung. Mit der Zentraleinheit können somit eine Vielzahl von Schranktürschlössern eine Anordnung, die eine Vielzahl von Schränken beinhaltet, verwaltet werden. Die Schranktürschlossverwaltung erfolgt als Folge der drahtlosen Datenfernübertragung ohne die Notwendigkeit von Leitungen, insbesondere von Busleitungen. Das Gehäuse besitzt eine Batterieaufnahme. Die Batterieaufnahme kann in demselben Gehäuse angeordnet sein, die auch den Riegel beinhaltet. Das Gehäuse kann aber auch aus mehreren, voneinander räumlich getrennten Einzelgehäusen ausgebildet sein, wobei die Batterie in einem vom Riegel getrennten Gehäuse angeordnet sein kann. Die Batterie dient insbesondere zur Energieversorgung des Motors oder der Kupplung, der elektronischen Schaltung, der Codeeingabeeinrichtung und der Sende-Empfangseinrichtung. Bevorzugt sind sämtliche elektrischen oder elektronischen Aggregate des Schranktürschlosses batteriebetrieben, sodass das Schranktürschloss keine Kabelverbindung mit einer externen Energieversorgung benötigt. Es handelt sich somit um ein autarkes Schloss, welches eine lange Betriebszeit besitzen kann, da es vorgesehen ist, dass die Sende-Empfangseinrichtung überwiegend ihren Ruhezustand einnimmt. Es ist vorgesehen, dass die Sende-Empfangseinrichtung nur nach einem vorgegebenen Zeitintervall ein Lebenszeichen an die Zentraleinheit sendet und ansonsten nur dann Schließzustandsdaten an die Zentraleinheit übermittelt, wenn die elektronische Schaltung aktiviert wird. Die Sende-Empfangseinrichtung geht nur dann in eine Empfangsbereitschaft, wenn sie zuvor aktiviert worden ist oder das zyklische Lebenszeichen abgesandt hat, wobei es ausreicht, wenn die Sende-Empfangseinrichtung einmal täglich ein diesbezügliches Lebenszeichen absendet. Dies minimiert den Energieverbrauch. Die elektronische Schaltung beinhaltet eine Uhr, die einen Takt vorgibt, nach dem ein Transponder-Erkennungssignal mit schwacher Leistung aufgebaut wird, um die Anwesenheit eines Transponders zu ermitteln, und das Lebenszeichen an die Zentraleinheit abgesandt wird. Funktionen mit einem größeren Energieverbrauch werden nur individuell nach einer Aktivierung vorgenommen. Anstelle einer drahtlosen Erfassung der Annäherung eines Transponders ist es aber auch möglich, einen Schalter vorzusehen, der bspw. durch Anlage des Transponders betätigt werden muss, um die Datenkommunikation mit dem Transponder zu starten. Die Codeeingabeeinrichtung kann als modulares Kommunikationsmodul ausgebildet sein. Dieses Kommunikationsmodul kann in einem Aufnahmefach des Gehäuses angeordnet sein. Das Kommunikationsmodul kann sich somit auf der Schrankinnenseite befinden. Bei dieser Anordnung ist die elektronische Schaltung nur durch die Annäherung eines Transponders aktivierbar. Die drahtlose Kommunikation mit dem Transponder erfolgt dann durch die insbesondere aus Holz bestehende Schranktür hindurch. Das Kommunikationsmodul kann aber auch auf der Türaußenseite montiert sein. Es ist dann über ein Kabel mit der elektronischen Schaltung verbunden. Bevorzugt steckt ein am Ende des Kabels befestigter Stecker in einer Einsteckbuchse der elektronischen Schaltung. Das Kommunikationsmodul kann als Türgriff verwendet werden. Das Schranktürschloss kann sowohl an links angeschlagenen als auch an rechts angeschlagenen Schranktürflügeln verwendet werden. Hierzu besitzt das Schranktürschloss einen Riegel, der bevorzugt länger ist, als die Breite des Schlosses und der mittels des Motors in Breitenerstreckungsrichtung hin und her fahrbar ist, sodass jeweils ein Ende des Riegels über das Gehäuse hinausragt. In einer ersten Betriebsstellung ragt ein erstes Ende des Riegels über eine erste Gehäuseseite. In einer zweiten Betriebsstellung des Riegels ragt ein zweites Ende des Riegels, das dem ersten Ende gegenüberliegt über eine zweite Gehäuseseite, die der ersten Gehäuseseite gegenüberliegt. Das Gehäuse besitzt Anschrauböffnungen, die entsprechend einem Lochbild angeordnet sind, das ein Schloss, wie es aus der eingangs genannten DE 19 832 516 A1 oder der DE 10 2007 052 583 A1 bekannt ist, besitzt. Das Schranktürschloss kann somit in einfacher Weise gegen ein konventionelles Schranktürschloss ausgetauscht werden. Es sind keine zusätzlichen Kabelverbindungen entweder zur Energieversorgung oder zu einer Datenkommunikation erforderlich. Gleichwohl lässt sich das Schloss in einfacherer Weise verwalten und lassen sich bevorzugt eine Vielzahl von gleichgestalteten Schranktürschlössern einer Schrankanordnung bspw. in einem Schwimmbad verwalten. Es ist somit möglich, auf Störungen zu reagieren. So ist es möglich, dass das Schranktürschloss ein oder mehrere Sensoren oder Sensorelemente aufweist, mit denen festgestellt werden kann, ob das Schloss eine elektronische, mechanische oder anderweitige Störung aufweist. Die elektronische Schaltung kann so eingerichtet sein, dass sie an die Zentraleinheit auch dann eine Statusmeldung absendet, wenn eine Störung ermittelt wird. Das Schranktürschloss sendet dann ein Alarm- oder Störsignal an die Zentraleinheit. Es ist ferner vorgesehen, dass mit den Sensoren oder Sensorelementen Vandalismus oder Aufbruchversuche festgestellt werden können, sodass über die Sende-Empfangseinrichtung ein Signal an die Zentraleinheit übermittelt wird. Mit diesem Alarmsignal kann ein stiller oder geräuschbehafteter Alarm ausgelöst werden. Es ist ferner möglich, auf den Verlust einer PIN oder eines Transponders zu reagieren, indem das Schranktürschloss bei einer x-beliebigen Aktivierung durch eine beliebige Tastenkombination oder durch einen beliebigen Transponder von der Zentraleinheit einen Öffnungsbefehl erhält, der bspw. veranlasst, dass der Motor den Riegel zurückzieht. Es ist auch vorgesehen, dass der Riegel nicht über einen Motor, sondern manuell vor- oder zurückgeschlossen werden kann.In its entirety, the cabinet door lock has the structural and functional features listed below. The cabinet door lock has a housing. The housing can be fastened to a cabinet door on the inside facing the interior of a cabinet. It can in particular be exchanged for a cabinet lock that is already there and does not have the technically advanced features of the invention. The housing contains a motor that can be controlled by electronic circuitry or a handle that can be coupled to a bolt drive. The electronic circuit interacts with a code input device. An opening code can be entered via the code input device. This can be done using a keyboard. The code can also be entered by holding a transponder close by. For this purpose, the code input device has a communication device that communicates wirelessly with the transponder. A wireless wake-up signal is sent to the transponder, so that the transponder sends its individual identifier to the code input device. The code input device can generate a test signal permanently or at intervals, which builds up an electromagnetic detector field to check whether a transponder is in the immediate vicinity of the cabinet door lock. This signal is generated with very low power, so it has no long-distance effect. Only when the presence of a transponder is detected in the immediate vicinity of the code input device is a more powerful wake-up signal generated, which causes the transponder to transmit its identifier. The code input device or the electronic circuit have a locking authorization checking device, which is used to check whether the opening code received via the keyboard or the transponder reading device has locking authorization. This test is based on an activation of the electronic circuit, which is done either by entering the PIN or reading the identifier of a transponder. If the locking authorization of the opening code is determined, i.e. when the electronic circuit is activated with locking authorization, the bolt can be shifted back and forth between two bolt positions with an actuating unit. For this purpose it can be provided that the motor is put into operation in order to shift the bolt, which can be shifted back and forth between two bolt positions, into the respective other bolt position. However, it is also provided that a clutch, which couples an actuating handle with a bolt drive, is brought from an uncoupled position into a coupled position, in which the actuation moves the bolt. The bolt is thus brought either into an open position in which the cabinet door can be opened, or into a locked position in which the cabinet door cannot be opened. A transceiver is provided which is functionally separate from the optional transponder reading device. This transceiver, which interacts with the electronic circuit, is used for wireless data transmission of at least locking status data to a central unit. Provision is made for locking state data to be transmitted to the central unit each time the electronic circuit is activated. The locking status data contain at least the locking status of the lock before or after entering the code and/or the entered code, i.e. the PIN or the individual transponder identification. The central unit can thus be used to manage a large number of cabinet door locks in an arrangement that includes a large number of cabinets. The cabinet door lock management takes place as a result of wireless data transmission without the need for cables, especially bus cables. The housing has a battery holder. The battery holder can be arranged in the same housing that also contains the latch. However, the housing can also be formed from a plurality of individual housings which are spatially separate from one another, it being possible for the battery to be arranged in a housing which is separate from the bolt. The battery serves in particular to supply energy to the motor or the clutch, the electronic circuit, the code input device and the transceiver. All electrical or electronic units of the cabinet door lock are preferably battery-operated, so that the cabinet door lock does not require a cable connection to an external power supply. It is therefore a self-sufficient lock, which can have a long operating time, since it is provided that the transceiver is mainly in its idle state. It is provided that the transceiver sends a sign of life to the central unit only after a predetermined time interval and otherwise only transmits locking status data to the central unit when the electronic circuit is activated. The transceiver only becomes ready to receive if it has previously been activated or has sent the cyclical sign-of-life, it being sufficient if the transceiver sends a relevant sign-of-life once a day. This minimizes energy consumption. The electronic circuitry includes a clock that provides a clock according to which a low-power transponder detection signal is built up to determine the presence of a transponder and the sign-of-life is sent to the central unit. Functions with a higher energy consumption are only carried out individually after activation. Instead of wireless detection of the approach of a transponder, however, it is also possible to provide a switch that has to be actuated, for example, by placing the transponder in place, in order to start data communication with the transponder. The code input device can be designed as a modular communication module. This communication module can be arranged in a compartment of the housing. The communication module can therefore be located on the inside of the cabinet. With this arrangement, the electronic circuit can only be activated by the approach of a transponder. The wireless communication with the transponder then takes place through the cabinet door, which is made of wood in particular. However, the communication module can also be mounted on the outside of the door. It is then connected to the electronic circuit via a cable. A plug attached to the end of the cable is preferably plugged into a socket of the electronic circuit. The communication module can be used as a door handle. The cabinet door lock can be used on cabinet door leaves hinged on the left as well as on the right. For this purpose, the cabinet door lock has a bolt which is preferably longer than the width of the lock and which can be moved back and forth in the width direction by means of the motor, so that one end of the bolt protrudes beyond the housing. In a first operating position, a first end of the latch projects beyond a first side of the housing. In a second operating position of the bolt, a second end of the bolt, which is opposite the first end, protrudes over a second side of the housing, which is opposite the first side of the housing. The housing has screw-on openings, which are arranged according to a hole pattern, which is a lock, as from the above-mentioned DE 19 832 516 A1 or the DE 10 2007 052 583 A1 is known, owns. The cabinet door lock can thus be exchanged for a conventional cabinet door lock in a simple manner. No additional cable connections are required either for power supply or for data communication. Nevertheless, the lock can be managed in a simpler way and preferably a large number of identically configured cabinet door locks in a cabinet arrangement, for example in a swimming pool, can be managed. It is thus possible to react to disturbances. It is thus possible for the cabinet door lock to have one or more sensors or sensor elements with which it can be determined whether the lock has an electronic, mechanical or other fault. The electronic circuit can be set up in such a way that it also sends a status message to the central unit when a fault is detected. The cabinet door lock then sends an alarm or fault signal to the central unit. Provision is also made for the sensors or sensor elements to be able to detect vandalism or attempted break-ins, so that a signal is transmitted to the central unit via the transceiver device. This alarm signal can be used to trigger a silent or noisy alarm. It is also possible to react to the loss of a PIN or a transponder by having the cabinet door lock receive an opening command from the central unit when it is activated by any combination of keys or by any transponder, which, for example, causes the motor to start the latch withdraws. Provision is also made for the bolt to be able to be closed or closed manually rather than by a motor.

Beschreibung der AusführungsformenDescription of the embodiments

Das Schranktürschloss S der Erfindung besitzt ein bspw. aus Kunststoff gefertigtes Gehäuse 1, welches auf der zum Innenraum eines Schrankes weisenden Innenseite einer Schranktür 10 eines Schrankes montierbar ist. Die Befestigung des Gehäuses 1 an der Schranktür 10 erfolgt mittels Schrauben 15, die durch Anschrauböffnungen 14 des Gehäuses 1 hindurch in das Türblatt eingeschraubt werden können. Die Anschrauböffnungen 14 befinden sich auf den Eckpunkten eines Rechtecks.The cabinet door lock S of the invention has a housing 1 made of plastic, for example, which can be mounted on the inside of a cabinet door 10 of a cabinet facing the interior of a cabinet. The housing 1 is fastened to the cabinet door 10 by means of screws 15 which can be screwed into the door leaf through screw-on openings 14 in the housing 1 . The screw-on openings 14 are located at the corners of a rectangle.

Innerhalb des Gehäuses 1 befindet sich ein Riegel 2. Beim Ausführungsbeispiel besitzt der Riegel 2 eine derartige Länge, dass er durch Betätigen eines Betätigungsaggregates 4 von einer ersten Betriebsstellung, in der ein Riegelkopf auf der linken Seite des Schlosses herausragt in eine zweite Betriebsstellung bringbar ist, in der ein Riegelkopf aus der rechten Schlossseite herausragt. Die Länge des Riegels kann dabei größer sein als der Abstand zweier gegenüberliegender Randkanten des Gehäuses. In der Figur 1 ist das linke Ende des Riegels 2 in seiner Verriegelungsstellung dargestellt. Das rechte Ende des Riegels 2 nimmt eine Offenstellung ein. Ein Betätigungsaggregat, bei dem es sich um einen Motor 4 oder um eine manuell verdrehbare Handhabe handeln kann, greift derart am Riegel 2 an, dass eine Betätigung des Betätigungsaggregates den Riegel von der in Figur 1 dargestellten ersten Stellung in die in der Figur 2 dargestellten zweiten Stellung sowie zurück in die erste Betriebsstellung verlagern kann. Hierzu kann bspw. ein Exzenterzapfen 3 in einen Querschlitz des Riegels 2 eingreifen.A bolt 2 is located inside the housing 1. In the exemplary embodiment, the bolt 2 has such a length that it can be brought from a first operating position, in which a bolt head protrudes on the left side of the lock, into a second operating position by actuating an actuating unit 4. in which a bolt head protrudes from the right side of the lock. The length of the bar can be greater than the distance between two opposite edges of the housing. In the figure 1 the left end of the bolt 2 is shown in its locked position. The right end of the bolt 2 takes an open position. An actuating unit, which can be a motor 4 or a manually rotatable handle, acts on the bolt 2 in such a way that actuation of the actuating unit moves the bolt from the in figure 1 shown in the first position in the figure 2 shown second position and can shift back to the first operating position. For this purpose, for example, an eccentric pin 3 can engage in a transverse slot of the bolt 2 .

Das Gehäuse 1 besitzt ein Batterieaufnahmefach 6. In dem Batterieaufnahmefach 6 können ein oder mehrere, bevorzugt drei Batterien 7 angeordnet sein. Die Batterien dienen der Energieversorgung des Schranktürschlosses S. Bevorzugt werden sämtliche elektrischen und elektronischen Verbraucher des Schranktürschlosses S durch die Batterien 7 leistungsversorgt.The housing 1 has a battery compartment 6. One or more, preferably three, batteries 7 can be arranged in the battery compartment 6. The batteries serve to supply energy to the cabinet door lock S. All electrical and electronic consumers of the cabinet door lock S are preferably supplied with power by the batteries 7 .

Innerhalb des Gehäuses befindet sich eine elektronische Schaltung 5. Die elektronische Schaltung 5 wirkt mit dem Elektromotor 4, einer Zugangskontrolleinrichtung 16, einer Codeeingabeeinrichtung 11 und einem Funkmodul 8 zusammen. Das Funkmodul 8 beinhaltet eine Sende-/Empfangseinrichtung, um Daten, insbesondere Schließzustandsdaten an eine Zentraleinheit Z zu übermitteln. Die Codeeingabeeinrichtung 11 kann ein Kommunikationsmodul sein, welches in einem Fach 9 des Gehäuses 1 Aufnahme finden kann. Über eine Kabelverbindung 17 ist das Kommunikationsmodul 11 mit der elektronischen Schaltung 5 verbunden. Die Zugangskontrolleinrichtung 16 kann körperlicher Teil der elektronischen Schaltung sein. Es kann sich hierbei um eine Mikrokontrolleranordnung handeln, die in der Lage ist, einen Öffnungscode auf Schließberechtigung zu überprüfen.An electronic circuit 5 is located inside the housing. The electronic circuit 5 interacts with the electric motor 4 , an access control device 16 , a code input device 11 and a radio module 8 . The radio module 8 contains a transmitter/receiver device in order to transmit data, in particular locking status data, to a central unit Z. The code input device 11 can be a communication module which can be accommodated in a compartment 9 of the housing 1 . Over a The communication module 11 is connected to the electronic circuit 5 by cable connection 17 . The access control device 16 can be a physical part of the electronic circuit. This can be a microcontroller arrangement that is able to check an opening code for locking authorization.

Die Figur 4 zeigt eine erste Einbauvariante des Schranktürschlosses S. Das Gehäuse 1 befindet sich auf der Innenseite einer Schranktür. Das Kommunikationsmodul 11 befindet sich auf der Außenseite der Schranktür und ist als Griff benutzbar. Über das Kabel 17, welches durch eine Öffnung des Türblattes 10 hindurchtritt, ist das Kommunikationsmodul 11 mit der elektronischen Schaltung 5 verbunden.the figure 4 shows a first installation variant of the cabinet door lock S. The housing 1 is on the inside of a cabinet door. The communication module 11 is located on the outside of the cabinet door and can be used as a handle. The communication module 11 is connected to the electronic circuit 5 via the cable 17 which passes through an opening in the door leaf 10 .

In einer zweiten Einbauvariante, die die Figur 6 zeigt, befindet sich das Kommunikationsmodul 11 in einer Aufnahmetasche 9, die sich auf der Anschraubseite des Gehäuses befindet.In a second installation variant, the figure 6 shows, the communication module 11 is in a receiving pocket 9, which is located on the screw-on side of the housing.

Das Kommunikationsmodul besitzt ein aus mehreren Tasten 12 bestehendes Tastenfeld, um einen Öffnungscode einzutippen. Es besitzt darüber hinaus eine Antennenanordnung 13, mit der eine Datenübertragungskommunikation mit einer RFID-Einrichtung, einem Transponder durchgeführt werden kann, um nach der Erkennung einer Annäherung eines Transponders an das Kommunikationsmodul 11 die digitale Kennung des Transponders auszulesen. Die Zugangskontrolleinrichtung 16 prüft dann, ob der eingegebene PIN oder die Transponderkennung eine Schließberechtigung aufweist. Das Eintippen eines Codes oder das Erkennen der Annäherung eines Transponders führt zu einer Aktivierung der elektronischen Schaltung 5, sodass über das Funkmodul 8 ein Datensatz an die Zentraleinheit Z gesandt wird. Im Anschluss daran besitzt die Sende-Empfangseinrichtung des Funkmoduls 8 für eine kurze Zeit eine Empfangsbereitschaft und ist in der Lage, Steuerungsdaten oder dergleichen von der Zentraleinheit Z zu empfangen. Bspw. kann es vorgesehen sein, dass die Sende-Empfangseinrichtung 8 den PIN oder die Transponderkennung an die Zentraleinheit Z übermittelt und letztere der Sende-Empfangseinrichtung 8 einen Schließ- oder einen Öffnungsbefehl schickt, sodass nur nach einer Überprüfung der Schließberechtigung durch die Zentraleinheit der Riegel vor- oder zurückgeschlossen werden kann. Es ist aber auch vorgesehen, dass das Schrankschloss S autark arbeitet und die Schließberechtigung selbst überprüft.The communication module has a keypad consisting of several keys 12 for typing in an opening code. It also has an antenna arrangement 13 with which data transmission communication can be carried out with an RFID device, a transponder, in order to read out the digital identifier of the transponder after the communication module 11 has detected that a transponder has approached. The access control device 16 then checks whether the entered PIN or the transponder identifier has locking authorization. Typing in a code or recognizing the approach of a transponder leads to activation of the electronic circuit 5 so that a data set is sent to the central unit Z via the radio module 8 . Following this, the transceiver has the radio module 8 for a short time a readiness to receive and is able to receive control data or the like from the central unit Z. For example, it can be provided that the transceiver 8 transmits the PIN or the transponder identifier to the central unit Z and the latter sends the transceiver 8 a locking or an opening command, so that only after the locking authorization has been checked by the central unit of the bolt can be advanced or reversed. However, it is also intended that the S cabinet lock works independently and checks the locking authorization itself.

Die Bezugsziffer 18 symbolisiert Sensoren oder Sensorelemente, mit denen bestimmte Betriebszustände des Schrankschlosses oder Schranks erfasst werden können. Mit diesen Sensoren oder Sensorelementen 18 kann bspw. das ordnungsgemäße Funktionieren des Schranktürschlosses S überprüft werden. Es ist ferner möglich, mit diesen Sensoren oder Sensorelementen 18 festzustellen, ob am Schranktürschloss Manipulationsversuche vorgenommen werden, sodass in einem derartigen Fall die Sende-Empfangseinrichtung 8 ein Alarmsignal an die Zentraleinrichtung Z übermittelt. Es kann somit auf Vandalismus und auf Störungen reagiert werden. Ferner ist es möglich, dass Schranktürschloss ferngesteuert zu öffnen oder zu schließen, bspw. um auf den Verlust eines Transponderschlüssels oder einer PIN zu reagieren. In diesem Falle reicht bereits eine Aktivierung der elektronischen Schaltung, durch Eingaben eines beliebigen PIN's oder durch Annähern eines beliebigen Transponders an das Kommunikationsmodul 11 aus, um den Riegel 2 zu verlagern.Reference number 18 symbolizes sensors or sensor elements with which specific operating states of the cabinet lock or cabinet can be detected. With these sensors or sensor elements 18, for example, the proper functioning of the cabinet door lock S can be checked. It is also possible to use these sensors or sensor elements 18 to determine whether manipulation attempts are being made to the cabinet door lock, so that the transceiver 8 transmits an alarm signal to the central device Z in such a case. It is thus possible to react to vandalism and disturbances. It is also possible to open or close the cabinet door lock remotely, for example to react to the loss of a transponder key or a PIN. In this case, activating the electronic circuit by entering any PIN or by approaching any transponder to the communication module 11 is sufficient to move the bolt 2 .

Die Figur 8 zeigt als Blockschaltbild eine Anordnung, wie sie bspw. in einem Schwimmbad anzutreffen ist. Dort stehen oftmals mehrere Hundert gleichgestalteter Schränke, die jeweils mit gleichgestalteten Schranktürschlössern S ausgestattet sind. Jedes der Schranktürschlösser S kommuniziert mit der Zentraleinheit Z, sodass sich mit einer Zentraleinheit Z über eine drahtlose Kommunikationsverbindung eine Vielzahl von autark arbeitender Schrankschlösser S verwalten lässt, ohne dass zu den einzelnen Schranktürschlössern Energieversorgungsleitungen führen müssen oder zwischen Schranktürschloss S und Zentraleinheit Z eine Datenübertragungsleitung vorhanden sein muss.the figure 8 shows a block diagram of an arrangement such as is found in a swimming pool, for example. There are often several hundred identically designed cabinets, each of which is equipped with identically designed cabinet door locks S. Each of the cabinet door locks S communicates with the central unit Z, so with a central unit Z via a wireless Communication link can manage a variety of self-sufficiently working cabinet locks S without having to lead power supply lines to the individual cabinet door locks or between cabinet door lock S and central unit Z a data transmission line must be present.

Das Schranktürschloss S arbeitet mit einem minimalen Energieaufwand. Die elektronische Schaltung 5 kann eine Uhr aufweisen, die in regelmäßigen Abständen veranlasst, dass das Kommunikationsmodul 11 mit schwacher Leistung ein Transpondererfassungssignal erzeugt, welches nur im Bereich unmittelbar um das Kommunikationsmodul 11 ein Transpondererfassungsfeld aufbaut. Nur wenn innerhalb des Transpondererfassungsfeldes ein Transponder erfasst wird, wird die elektronische Schaltung zur Datenkommunikation mit dem Transponder aktiviert bzw. sendet die Sende-Empfangseinrichtung 8 Schließzustandsdaten an die Zentraleinheit Z und geht für eine vorgegebene Zeit in einen Empfangsmodus, in dem sie in der Lage ist, Daten von der Zentraleinheit Z zu empfangen. Ansonsten befindet sich die Sende-Empfangseinrichtung in einem Ruhezustand. Die Batterien haben somit eine sehr lange Standzeit.The cabinet door lock S works with minimal energy consumption. The electronic circuit 5 can have a clock which causes the communication module 11 to generate a low-power transponder detection signal at regular intervals, which only establishes a transponder detection field in the area immediately around the communication module 11 . Only when a transponder is detected within the transponder detection field is the electronic circuit for data communication with the transponder activated or does the transceiver 8 send locking status data to the central unit Z and goes into a receiving mode for a specified time in which it is able to receive data from the central unit Z. Otherwise the transceiver is in an idle state. The batteries therefore have a very long service life.
