Description
Die Erfindung bezieht sich auf ein elektronisch-mechanisches Schließsystem gemäß den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to an electronic-mechanical locking system according to the features indicated in the preamble of
Dokument
Bekannte elektronische Schließeinrichtungen arbeiten entweder mit Codenummern, welche über besondere Eingabeeinheiten einzugeben sind, oder mit "Schlüsseln", die bei Ausbildung als Karten unhandlich beziehungsweise nicht kopiersicher sind. Eine Änderung am Schloß oder sonstigen mechanischen oder elektromechanischen Schließeinrichtungen der bekannten elektronischen Systeme, wie beispielsweise die Änderung von Berechtigungen, erfordert einen erheblichen Aufwand. Ferner sind Systeme, welche zusätzlich die Protokollierung von Schlüssel, Zeit und Datum ermöglichen, aufwendig und erfordern zusätzliche Hardware. Bei Stromausfall ist meist nur für einem begrenzten Zeitraum eine Notstromversorgung sichergestellt. Ferner sei auf rein mechanische Schließanlagen verwiesen, welche recht komplexe Systeme darstellen und einen erheblichen Aufwand zur Berechnung und Fertigung erfordern. Hinzu kommt ein hoher Aufwand bei Schlüsselverlust, da alle Schließzylinder geändert werden müssen.Known electronic locking devices work either with code numbers, which are to be entered via special input units, or with "keys" that are unwieldy or not copy-proof when formed as cards. A change in the lock or other mechanical or electromechanical locking devices of the known electronic systems, such as the change of permissions, requires considerable effort. Furthermore, systems which additionally enable logging of key, time and date are expensive and require additional hardware. In the event of a power failure, an emergency power supply is usually only ensured for a limited period of time. Furthermore, reference is made to purely mechanical locking systems, which represent quite complex systems and require considerable effort for calculation and production. In addition, a lot of effort in key loss, since all lock cylinders must be changed.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein elektronisch-mechanisches Schließsystem der genannten Art dahingehend weiterzubilden, daß neben einfacher Handhabung des Schließvorganges auch eine hohe Sicherheit und einfache Änderung der Berechtigung realisiert ist. Die Schließeinrichtung soll einen kompakten und darüberhinaus aufbruchsicheren Aufbau aufweisen. Die gesamte Schließeinrichtung soll in einem Türbeschlag Platz finden und die Bedienung soll nur über eine Schnittstelle erfolgen können. Darüberhinaus soll die Protokollierung der "Schlüssel", inclusive Zeit und Datum, ermöglicht werden. Schließlich soll auch bei Stromausfall jederzeit das Öffnen möglich sein ohne hierbei das zugrundeliegende Sicherheitskonzept zu verlieren.Proceeding from this, the invention has the object, an electronic-mechanical locking system of the type mentioned in such a way that in addition to simple handling of the closing process and a high level of security and ease of change Authorization is realized. The locking device should have a compact and moreover break-proof construction. The entire locking device should find place in a door fitting and the operation should be possible only via an interface. In addition, the logging of the "key", including time and date, should be possible. After all, even in the event of a power failure, it should be possible to open at any time without losing the underlying security concept.
Die Lösung dieser Aufgabe erfolgt gemäß den in dem Patentanspruche 1 angegebenen Merkmalen.The solution of this task is carried out according to the features specified in the
Das vorgeschlagene elektronisch-mechanische Schließsystem zeichnet sich durch eine einfache und funktionssichere Konstruktion aus und ermöglicht mit geringem Aufwand die Vorgabe und Veränderung der Zugriffsberechtigung. Als "Schlüssel" ist ein Speicherelement mit einem nicht veränderbaren eincodierten Datensatz vorgesehen. Dieser Datensatz ist in zweckmäßiger Weise beim Fertigungsprozeß des Speicherelements in dieses eingegeben, und zwar insbesondere durch fortlaufende Durchnumerierung der Seriennummer der gefertigten Speicherelemente. Es liegt für das jeweilige Speicherelement ein weltweit einmalig vergebener Datensatz, insbesondere als Seriennummer in dem ersten Speicherelement fest, wodurch eine nahezu hundertprozentige Kopiersicherheit gewährleistet wird. Als erste Speicherelemente gelangen insbesondere ROM-Chips der Firma Dallas zum Einsatz. Darüberhinaus ist es von besonderer Bedeutung, daß die zum Einsatz gelangenden ersten Speicherelemente oder ROM-Chips in der Zweidraht-Technologie ausgeführt sind, also nur zwei Drähte oder Leitungen zum Herstellen der elektrischen Verbindung mit weiteren Bauteilen aufweisen. Die Betätigung der Schließeinrichtung erfolgt durch einfaches Kontaktieren mit dem berechtigten Schlüssel beziehungsweise ersten Speicherelement oder ROM-Chip. Im Türbeschlag ist ein Prozessor vorgesehen, mit welchem der Datensatz des ersten Speicherelements auslesbar und mit dem Inhalt eines Speichers vergleichbar ist. In dem zweckmäßig in den Prozessor integrierten Speicher sind die Datensätze der Zugriffsberechtigten weitere Elemente eingetragen. Bei Übereinstimmung des eingelesenen Datensatzes mit einem in den Speicher eingetragenen wird zweckmäßig elektromechanisch die Öffnung des Schloßes ermöglicht. Zur Änderung des Speicherinhalts des Prozessorspeichers gelangt erfindungsgemäß ein zweites Speicherelement zum Einsatz, welches wiederum einen nicht veränderbaren Datensatz, insbesondere eine einmalige Seriennummer, enthält. Dieses zweite Speicherelement ist insbesondere als RAM-Chip der Firma Dallas ausgebildet. Wesentlich ist, daß dieser zweite, nicht veränderbare Datensatz bei der Herstellung des Prozessors fest, in insbesondere dessen Quellcode eingetragen wird und nicht veränderbar ist. Somit ist gewährleistet, daß jeweils nur ein einziges zweites Speicherelement Zugang zu dem jeweiligen Prozessor erhält. Das zweite Speicherelement oder der RAM-Chip enthält außer dem nicht veränderbaren Datensatz bzw. seiner Seriennummer noch einen frei schreib- und lesbaren Speicherbereich, welcher über eine geeignete entsprechend abgestimmte PC-Software beschrieben und gelesen werden kann. Diese PC-Software ermöglicht den Eintrag einer vorgegebenen Anzahl von Datensätzen der ersten Speicherelemente bzw. Schlüssel, beispielsweise bis zu 320 Schlüsseln in den dem Prozessor zugeordneten Speicher. Ferner wird mittels des Programms eine Zuordnung von beliebig vielen Schlüsseln zu beliebig vielen Schlössern bzw. deren Prozessorspeicher vorgenommen und verwaltet. Das derart beschriebene zweite Speicherelement wird dann wie ein Schlüssel mit dem nur für ihn zugelassenen Prozessor kontaktiert und die Schlüsseldaten werden in den dem Prozessor zugeordneten Speicher übernommen. Das zweite Speicherelement dient erfindungsgemäß als Datentransportmedium und macht somit eine Änderung der Berechtigung am Schloß vor Ort sehr einfach. Ohne das dem Prozessor definiert zugeordnete zweite Speicherelement ist hingegen ein Datenaustausch und insbesondere eine Änderung des Speicherinhalts des Prozessors nicht möglich, so daß unerlaubte Manipulationen ausgeschlossen sind. Andererseits ist eine Änderung des Speicherinhalts und letztendlich der Zugangsberechtigungen am Schloß beziehungsweise Türbeschlag vor Ort ohne weiteres mittels des berechtigten zweiten Speicherelements problemlos durchführbar.The proposed electronic-mechanical locking system is characterized by a simple and functionally reliable construction and allows the specification and modification of the access authorization with little effort. As a "key" a memory element is provided with a non-variable encoded record. This data set is expediently entered in the manufacturing process of the memory element in this, in particular by consecutive numbering of the serial number of the manufactured memory elements. It is for the respective memory element a record unique worldwide awarded, in particular as a serial number in the first memory element, which ensures almost 100% copy security. The first memory elements are used in particular ROM chips from Dallas. Moreover, it is of particular importance that the used reaching first memory elements or ROM chips are designed in two-wire technology, so only two wires or lines for making the electrical connection have with other components. The actuation of the locking device is effected by simply contacting with the authorized key or first memory element or ROM chip. In the door fitting a processor is provided with which the record of the first memory element is readable and comparable to the content of a memory. In the memory which is expediently integrated into the processor, the data records of the authorized users are entered further elements. In accordance with the read record with a registered in the memory is expediently electromechanically allows the opening of the lock. To change the memory contents of the processor memory, according to the invention, a second memory element is used, which in turn contains a non-changeable data record, in particular a unique serial number. This second memory element is designed in particular as a RAM chip from Dallas. It is essential that this second, unchangeable record in the production of the processor fixed, in particular its source code is entered and is not changeable. This ensures that only a single second memory element receives access to the respective processor. The second memory element or the RAM chip contains, in addition to the unchangeable data record or its serial number, a freely writable and readable memory area which can be written and read via a suitable suitably matched PC software. This PC software allows the entry of a predetermined number of records of the first memory elements or keys, for example, up to 320 keys in the memory associated with the processor. Furthermore, an allocation of any number of keys to any number of locks or their processor memory is made by means of the program and managed. The second memory element described in this way is then contacted like a key with the processor authorized for it only, and the key data is transferred to the memory assigned to the processor. The second memory element is used according to the invention as a data transport medium and thus makes a change in the right to the castle on site very easy. On the other hand, without the second memory element allocated to the processor, a data exchange and in particular a change of the memory contents of the processor is not possible, so that unauthorized manipulations are excluded. On the other hand, a change of the memory contents and ultimately the access rights to the lock or door fitting on site readily by means of the legitimate second memory element easily be performed.
In einer zweckmäßigen Ausgestaltung ist im Türbeschlag ein weiterer Speicher vorgesehen, welcher vor allem zur Protokollierung von Schließvorgängen genutzt wird. So kann beim Kontaktieren der Schließeinrichtung mit einem Schlüssel und/oder beim Öffnen der Datensatz des ersten Speicherelements beziehungsweise des verwendeten Schlüssels in dem weiteren Speicher abgelegt werden. Gleichzeitig wird bevorzugt auch der Dateninhalt einer Funkuhr, insbesondere einer DCF 77-Funkuhr, ausgelesen und gemeinsam mit dem genannten Datensatz in dem weiteren Speicher abgelegt. Zum Auslesen derartiger Protokolldaten wird das dem jeweiligen Prozessor zugeordnete zweite Speicherelement beziehungsweise RAM-Chip, insbesondere mittels des genannten PC-Programms, zum Auslesen vorbereitet. Das derart vorbereitete zweite Speicherelement wird wiederum lediglich mit dem Beschlag bzw. dem Prozessor kontaktiert, um die eingelesenen Daten im PC auswerten zu können.In an expedient embodiment, a further memory is provided in the door fitting, which is mainly used for logging closing operations. Thus, when contacting the locking device with a key and / or when opening the record of the first memory element or the key used in the further memory are stored. At the same time, the data content of a radio clock, in particular a
In einer zweckmäßigen Weiterbildung ist ferner ein Notladegerät vorgesehen, welches bei Stromausfall gleichwohl die Betätigung der Schließeinrichtung und somit das Öffnen einer Tür oder dergleichen ermöglicht. Hierzu ist in den Türbeschlag eine Hilfs-Stromquelle, insbesondere in Form eines Kondensators, integriert. Diese Hilfs-Stromquelle wird über die gleiche Kontaktstelle geladen, welche für die ersten oder zweiten Speicherelemente vorgesehen sind. Durch eine besondere Ladeelektronik wird gewährleistet, daß die übrige im Türbeschlag angeordnete Elektronik, insbesondere der Prozessor abgekoppelt ist. Nach dem Ladevorgang kann mit dem zugeordneten Schlüssel beziehungsweise ROM-Chip insbesondere einmalig ein Öffnungsvorgang erfolgen. Das Laden und anschließende Öffnen kann jederzeit wiederholt werden.In an expedient development, an emergency charger is also provided, which nevertheless allows the operation of the locking device and thus the opening of a door or the like in case of power failure. For this purpose, an auxiliary power source, in particular in the form of a capacitor integrated in the door fitting. This auxiliary power source is charged via the same contact point provided for the first or second memory elements. By a special charging electronics ensures that the rest arranged in the door fitting electronics, in particular the processor is disconnected. After the loading process, an opening process can be carried out in particular once with the associated key or ROM chip. Loading and subsequent opening can be repeated at any time.

Außerdem ist die Anordnung eines Kontaktstiftes 16 in Verbindung mit einer Isolationshülse 17 und der Befestigung durch die Mutter 21 gezeigt.With regard to the mechanical structure of the locking system, the fitting has an
Das elektrische Kupplungselement 14 weist zum Außenschild 1 hin einen Wechselstift 15 auf, der in den Drehknopf 38 eingreift, wobei die Lagerung in einem Einsatzstück 39 erfolgt und zwar in einem dort ausgebildeten Lager 41, wobei dieses Einsatzstück in einer Bohrung des Außenschildes 1 eingesetzt ist. Dieses Einsatzstück 39 ist zu dem Drehknopf 38 hin mit einem Absatz 48 als Ziehschutz versehen und stützt sich an einem Vorsprung 50 des Außenschildes 1 ab. Dieser Vorsprung 50 wird mittels des Drehknopfes 38 durch einen Materialüberstand 42 abgedeckt.The
An der gegenüberliegenden Seite des Kupplungselementes 14 ist ein Betätigungsstift 40 angeordnet, der in eine Schließnase 44 mit einem Vierkant-Innenausbruch eingreift. Diese Schließnase 44 betätigt ein Schloß, beispielsweise ein selbstverriegelndes Einsteckschloß 37, wobei aber alle Schlösser einsetzbar sind, die über Schließzylinder betätigbar sind. Zur Lagerung der Schließnase dient ein Verbindungssteg 45, der über die bei solchen Einsteckschlössern vorgesehene Befestigungsschraube 51, mit der üblicherweise Schließzylinder befestigt werden, gehaltert ist. Zu beiden Seiten sind Lagerbolzen 52 vorhanden, auf denen Lagerböcke 46 unverdrehbar aufgesteckt sind, zwischen denen wiederum Ringscheiben 53 vorgesehen sind, die die Nase 44 lagern.On the opposite side of the
Das System ist innen mit Hilfe eines Innenschildes 38 abgedeckt und von innen her betätigbar mit Hilfe eines Drückers 43 mit Wechselstift 49. Das Außenschild 1 wird innen mit einer Abdeckplatte 47 abgedeckt. Durch diese Ausgestaltung des Außenschildes 1 kann das System vormontiert werden, wodurch die Montage erleichtert wird. Nachdem der Betätigungsstift 40 eine Drehbewegung ausführt ist es zweckmäßig, den elektrischen Anschluß 54 über Schleifringe zu bewerkstelligen. Sowohl das Außenschild 1 als auch der Kontaktstift 16 bestehen aus gehärtetem Stahl.The system is covered inside with the help of an
In entsprechender Weise ist ein hier nicht weiter dargestelltes Kontaktelement ausgebildet, welches dem zweiten Speicherelement bzw. RAM-Chip zugeordnet ist. Über das Kontaktelement erfolgen die Verbindungen mit der erläuterten PC-Software und die Übernahme der in den RAM-Chip eingetragenen Schlüsseldaten in den Prozessorspeicher.In a corresponding manner, a contact element (not further illustrated here) is formed which is assigned to the second memory element or RAM chip. The connections to the explained PC software and the transfer of the key data entered into the RAM chip into the processor memory are effected via the contact element.

Zum Kuppeln des Wechselstiftes 15 mit dem Betätigungsstift 40 dient ein Elektromagnet, der innerhalb des Lagers 41 des Einsatzstückes 39 angeordnet ist. Dazu ist in ein Magnetgehäuse 59 ein Spulenkörper 60 eingesetzt, wobei das Magnetgehäuse 59 mit seinem Anschlagring 56 innerhalb des Einsatzstückes 39 gehaltert ist. Auf dem Bolzenteil 67 des Wechselstiftes 15 ist mit Hilfe eines quer durchgesteckten Stiftes 61 (
Der Wechselstift 15 ist mit seinem Bolzenteil 67 mit dem Betätigungsstift 40 in seiner axialen Bohrung 69 axial verschiebbar, jedoch nicht verdrehgesichert, mit Hilfe eines Spannstiftes 62 gekoppelt, der in einer Vertiefung 68 in der axialen Bohrung 69 des Stiftes 40 angeordnet ist (
Das Ende des Buchsenteiles 66 des Ankers 57 ist als Klaue 63 ausgebildet, die über ein entsprechend ausgebildetes Endteil als Rastelement 64 des Betätigungsstiftes 40 geschoben werden kann (
Die Angriffsfläche der Klaue 63 und die entsprechenden Angriffsflächen des Rastelementes 64 sind gegenüber der Waagerechten um einen Winkel α verschoben, so daß ausgehend von der Nullstellung bei erregtem Magneten der Wechselstift 15 bereits nach verdrehen um den Winkel α am Betätigungsstift 40 einrastet und die beiden Teile somit gekuppelt sind.The engagement surface of the
Das beschriebene Schließsystem ist für alle elektro-mechanischen Schlösser, wie Tresorschlösser, Einsteckschlösser, Kastenschlösser, Mehrpunktverriegelungsschlösser, Zutrittskontrollschlösser u. dgl. verwendbar, d. h. Schlösser, die über eine mechanische Welle betätigbar sind. Hierbei ergibt sich über die Klaue ein sicherer Eingriff und es läßt sich ein größeres Drehmoment übertragen. Daraus ergibt sich aber wiederum eine geringere Stromaufnahme und damit auch ein kleinerer Kondensator für den Notstrombetrieb.The locking system described is suitable for all electro-mechanical locks, such as safe locks, mortise locks, box locks, Multipoint Locks, Access Control Locks & Locks Like. Usable, ie locks that can be actuated via a mechanical shaft. This results in a secure engagement on the claw and it can be a greater torque transmitted. This in turn results in a lower power consumption and thus also a smaller capacitor for emergency power operation.
Nachdem sich der Anschluß 54 der elektrischen Kabel zusammen mit dem Betätigungsstift 40 verdreht, wird die Gefahr eines Kabelbruches oder sonstiger Beschädigungen vermieden.After the

Das Betätigungselement weist einen verdickten zylindrischen Teil 80 auf, an den sich ein Wechselstift 15 anschließt, wobei in einem Abstand zum zylindrischen Teil 80 ein Mehrkant-Abschnitt, beispielsweise ein Vierkant-Abschnitt 76 anschließt. Im vorderen Teil des Wechselstiftes 15 ist dieser mit einer Einschnürung 77 versehen.The actuating element has a thickened
Das Betätigungsteil 38 weist eine zylindrische Welle 72 auf, an die, zum Betätigungselement 40 hin, ein scheibenförmiges vergrößertes Aufnahmeteil 73 anschließt. Die Welle 72 ist mit einem Sackloch 79 versehen, in das der Wechselstift 15 eingesteckt wird. Das Aufnahmeteil 73 weist eine in etwa ovalförmige, sich achsial erstreckende Ausnehmung 81 auf.The actuating
Zum Kuppeln des Betätigungsteiles 38 mit dem Betätigungselement 40 dient ein scheibenförmiges Kupplungsteil 74, das auf dem Wechselstift 15 verschiebbar ist und in der Mitte eine Mehrkantausnehmung 78 aufweist. Die Höhe dieses Kupplungsteiles 74 ist geringer als die Höhe der Ausnehmung 81, so daß dieses Teil 74 innerhalb der Ausnehmung 81 einen Verschiebeweg besitzt. Die Mehrkantausnehmung 78 korrespondiert mit dem Mehrkantabschnitt 76 des Wechselstiftes 15. Zum Verschieben des Kupplungsteiles 74 dient ein Elektromagnet 60, dessen Spule mit elektrischem Anschluß 54 in einem Magnetgehäuse bzw. einer Spulenhalterung 59 angeordnet ist. Die Spulenhalterung 59 ist am Beschlag oder einem Einsatzstück des Beschlages befestigt. Sie sitzt im Bereich eines Abschnittes 82 des Wechselstiftes 15. Zwischen der Spule 60 und dem Kupplungsteil 74 befindet sich eine Feder 75. Weiterhin sind das Betätigungsteil 38 und das Betätigungselement 40 axial durch einen Sicherungsstift 83 im Betätigungsteil 38 und einer Einschnürung 77 am Vorderteil des Wechselstiftes 15 gehalten.For coupling the actuating
Zum Einkuppeln wird der Elektromagnet 60 erregt, wodurch das Kupplungsteil 74 gegen die Feder 75 und den Mehrkantabschnitt 76 des Wechselstiftes 15 verschoben wird, dabei aber aus der Ausnehmung 81 des Aufnahmeteiles 73 nicht ausrastet. Es wird dabei mit seiner Mehrkant-Ausnehmung 78 über den Mehrkant-Abschnitt 76 des Wechselstiftes 15 geschoben und damit die Kupplung bewirkt. Sobald der Elektromagnet 60 abgeschaltet ist, wird das Kupplungteil 74 durch die Feder 75 gegen das Betätigungsteil 38 innerhalb der Ausnehmung 81 verschoben und gelangt dabei zu dem Mehrkant-Abschnitt 76 des Wechselstiftes 15 außer Eingriff.To engage the
Diese Ausführungsform hat insbesondere den Vorteil, daß die Gefahr von Beschädigungen des elektrischen Anschlusses am Kupplungselement vermieden und der konstruktive Aufwand vereinfacht wird.This embodiment has the particular advantage that the risk of damage to the electrical connection to the coupling element avoided and the design complexity is simplified.
