Definitions
- the invention relates to a lock device, as they are usually used on containers and furniture, which are subject to higher-level management and relatively frequent user changes.
- Locking lockers and storage cabinets (lockers), office furniture, switchgear and tool cabinets in schools, businesses and sports facilities is the most common application.
- Lock devices of this type consist of a combination lock, which is usually designed as a combination lock and a secondary lock, which is usually designed as a master key to be operated cylinder lock.
- the combination lock is intended for normal operation and assigned to the users of the cabinets. It usually has several numbered or lettered control wheels, by means of which an opening code is set.
- the combination locks provided with the factory-preset opening code can be reprogrammed by the user to a personal opening code and changed again at any time.
- the combination lock must always be in the open position or the currently valid opening code must be known. If the opening code is lost or forgotten, the combination lock can not be opened or the opening code can be changed.
- the secondary lock is used for emergency opening and is assigned to the owner or administrator of the cabinets.
- An emergency opening is required, for example, when a cabinet user has lost or forgotten his personal opening code, a user can no longer be found, or if control of the content must also take place without the presence of the user in order to prevent crime or to avoid danger.
- the combination lock is usually simply bridged, so that with the master key each cabinet or lock device, even without knowledge of Opening codes, opens. Accordingly, the master key must be kept by the administrator.
- lock devices such as those in the EP 2 419 586 and US 8,087,274 moreover, have a function for automatically discarding the opening code during the opening movement of the lock device. This function is intended to ensure that the set and therefore visible opening code is automatically blurred after opening the lock device and does not remain visible for an unnecessarily long time. When blurring so only the adjusting wheels are rotated out of the opening code out in a specific predetermined position. The valid opening code is retained.
- the code discovery represents a considerable security gap because the supposedly secure personal opening codes can basically be read out by any unauthorized person who, even if only for a short time, obtains the master key.
- the particular risk of this is that the reading of the personal code remains completely unnoticed when the master key is put back in place. Thieves could gain regular access in this way.
- program the described Codefinding function is even more critical especially as most users are probably unaware that this code discovery function exists.
- the other major drawback is the extra time required to find the lost opening code to reset a lock to its delivery condition.
- the compulsion to code can mean a significant effort for the administrator, because vacant cabinets or locks are usually left by the users with their personally set codes.
- the scanning of the individual adjusting wheels with an additional tool is very time consuming.
- the present invention seeks to provide a lock device that is reset in factory settings and in the retrieval of a lost opening code is neither possible nor necessary and thus provides security against reading the personal opening code and about
- a quick and comfortable management of the lock device ensures when users change frequently.

Description
Die Erfindung bezieht sich auf eine Schlossvorrichtung, wie sie in der Regel an Behältnissen und Möbeln eingesetzt werden, die einer übergeordneten Verwaltung und relativ häufigen Nutzerwechseln unterliegen. Das Verschließen von Umkleide- und Aufbewahrungsschränken (Spinde), Büromöbeln, Schalt- und Werkzeugschränken in Schulen, Unternehmen und Sportstätten ist dabei die häufigste Anwendung. Schlossvorrichtungen dieser Art bestehen aus einem Kombinationsschloss, das meist als Zahlenschloss und einem Sekundärschloss, das meist als ein mit Hauptschlüssel zu betätigendes Zylinderschloss ausgeführt ist.The invention relates to a lock device, as they are usually used on containers and furniture, which are subject to higher-level management and relatively frequent user changes. Locking lockers and storage cabinets (lockers), office furniture, switchgear and tool cabinets in schools, businesses and sports facilities is the most common application. Lock devices of this type consist of a combination lock, which is usually designed as a combination lock and a secondary lock, which is usually designed as a master key to be operated cylinder lock.
Das Kombinationsschloss ist für den Normalbetrieb vorgesehen und den Nutzern der Schränke zugeordnet. Es verfügt in der Regel über mehrere mit Zahlen oder Buchstaben versehene Stellräder, mittels deren ein Öffnungscode eingestellt wird. Bei erstmaliger Benutzung können die mit werksseitig voreingestelltem Öffnungscode versehenen Kombinationsschlösser vom Nutzer auf einen persönlichen Öffnungscode umprogrammiert und jederzeit wieder geändert werden. Zum Ändern des Öffnungscodes muss sich das Kombinationsschloss immer in Offenstellung befinden bzw. der aktuell gültige Öffnungscode bekannt sein. Bei verlorenem bzw. vergessenem Öffnungscode lässt sich das Kombinationsschloss weder öffnen, noch der Öffnungscode ändern.The combination lock is intended for normal operation and assigned to the users of the cabinets. It usually has several numbered or lettered control wheels, by means of which an opening code is set. When used for the first time, the combination locks provided with the factory-preset opening code can be reprogrammed by the user to a personal opening code and changed again at any time. To change the opening code, the combination lock must always be in the open position or the currently valid opening code must be known. If the opening code is lost or forgotten, the combination lock can not be opened or the opening code can be changed.
Das Sekundärschloss dient zur Notöffnung und ist dem Eigentümer bzw. Verwalter der Schränke zugeordnet. Eine Notöffnung wird z.B. dann erforderlich, wenn ein Schranknutzer seinen persönlichen Öffnungscode verloren bzw. vergessen hat, ein Nutzer nicht mehr auffindbar ist oder wenn zur Verhinderung von Straftaten oder zur Gefahrenabwehr eine Kontrolle des Inhaltes auch ohne Beisein des Nutzers erfolgen muss. Mit dem Sekundärschloss wird das Kombinationsschloss in der Regel einfach überbrückt, so dass sich mit dem Hauptschlüssel jeder Schrank bzw. jede Schlossvorrichtung, auch ohne Kenntnis des Öffnungscodes, öffnen lässt. Entsprechend sorgfältig muss der Hauptschlüssel vom Verwalter aufbewahrt werden.The secondary lock is used for emergency opening and is assigned to the owner or administrator of the cabinets. An emergency opening is required, for example, when a cabinet user has lost or forgotten his personal opening code, a user can no longer be found, or if control of the content must also take place without the presence of the user in order to prevent crime or to avoid danger. With the secondary lock, the combination lock is usually simply bridged, so that with the master key each cabinet or lock device, even without knowledge of Opening codes, opens. Accordingly, the master key must be kept by the administrator.
Um ein Kombinationsschloss, dessen Öffnungscode verloren ist, wieder nutzbar zu machen bzw. den werkseitig vorgegebenen Öffnungscode wieder herzustellen, verfügen die zum Stand der Technik gehörenden Schlossvorrichtungen in der Regel über eine Funktion zur Codefindung, die natürlich nur im Notöffnungsbetrieb bzw. im notgeöffnetem Zustand verfügbar ist.In order to make a combination lock whose opening code is lost again usable or to restore the factory default opening code, belonging to the prior art lock devices usually have a function for code finding, of course, only in emergency opening operation or in Notopen state available is.
Die aus dem Stand der Technik bekannten und auf dem Markt befindlichen Schlossvorrichtungen bedienen sich für die Codefindung unterschiedlicher Lösungen. Aus den

Während die Funktion des automatischen Verwischens durchaus sinnvoll ist, weil damit die Sicherheit gegen Ausspähen des Öffnungscodes erhöht wird, hat die Funktion der Codefindung mindestens zwei erhebliche Nachteile.While the function of automatic blurring makes sense, because it increases the security against spying on the opening code, the function of finding a code has at least two significant disadvantages.
Zum einen stellt die Codefindung eine erhebliche Sicherheitslücke dar, weil die vermeintlich sicheren persönlichen Öffnungscodes grundsätzlich von jedem Unbefugten ausgelesen werden können, der, wenn auch nur für kurze Zeit, in den Besitz des Hauptschlüssels gelangt. Das besondere Risiko daran ist, dass das Auslesen der persönlichen Codes völlig unbemerkt bleibt, wenn der Hauptschlüssel wieder an seinen Platz gelegt wird. Diebe könnten sich auf diese Weise einen regelmäßigen Zugang verschaffen. Berücksichtigt man noch die Tatsache, dass viele Nutzer trotz und entgegen allgemein bekannter Sicherheitsratschläge aus Angst davor, den Öffnungscode zu vergessen, gerne einen ihnen vertrauten Code, welchen sie schon zur Verschlüsselung an anderen Schlössern oder Geräten verwenden, einprogrammieren, ist die beschriebene Codefindungsfunktion noch kritischer zu betrachten, zumal den meisten Nutzern wahrscheinlich gar nicht bewusst ist, dass diese Codefindungsfunktion existiert.On the one hand, the code discovery represents a considerable security gap because the supposedly secure personal opening codes can basically be read out by any unauthorized person who, even if only for a short time, obtains the master key. The particular risk of this is that the reading of the personal code remains completely unnoticed when the master key is put back in place. Thieves could gain regular access in this way. Considering the fact that many users despite and contrary to well-known security advice for fear of forgetting the opening code, like a familiar code, which they already use for encryption on other locks or devices, program the described Codefinding function is even more critical especially as most users are probably unaware that this code discovery function exists.
Der andere wesentliche Nachteil liegt in dem zusätzlichen Zeitaufwand, der zum Finden des verlorenen Öffnungscodes benötigt wird, um ein Schloss in seinen Auslieferungszustand zurückzusetzen. Besonders da, wo relativ häufige Nutzerwechsel stattfinden, wie z.B. in Sportstätten oder Betrieben mit einem hohem Anteil an Leihpersonal oder Saisonkräften, kann der Zwang zur Codefindung einen erheblichen Aufwand für den Verwalter bedeuten, weil frei werdende Schränke bzw. Schlösser von den Nutzern in der Regel mit ihren persönlich eingestellten Codes hinterlassen werden. Insbesondere das Abtasten der einzelnen Stellräder mit einem zusätzlichen Werkzeug ist dabei sehr zeitraubend.The other major drawback is the extra time required to find the lost opening code to reset a lock to its delivery condition. Especially where relatively frequent user changes take place, such as in sports facilities or businesses with a high proportion of temporary staff or seasonal forces, the compulsion to code can mean a significant effort for the administrator, because vacant cabinets or locks are usually left by the users with their personally set codes. In particular, the scanning of the individual adjusting wheels with an additional tool is very time consuming.

Da es bei einer Schlossvorrichtung, dessen Öffnungscode verloren ist, letztendlich nur darum geht, das Kombinationsschloss wieder in einen Zustand mit vorgegebenem Öffnungscode, wie z.B. den Werkscode, zurückzusetzten, ist das vorher erforderliche Auffinden des gültigen Öffnungscodes eine rein konstruktionsbedingte Notwendigkeit, die nur Nachteile bringt.Since, in the case of a lock device whose opening code is lost, the ultimate goal is simply to return the combination lock to a condition with a predetermined opening code, such as a lock. To reset the factory code, the previously required finding the valid opening code is a purely design-related need that brings only disadvantages.
Ausgehend von dem vorstehend geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Schlossvorrichtung zu schaffen, die in Werkseinstellung rücksetzbar ist und bei der das Wiederauffinden eines verlorenen Öffnungscodes weder möglich noch nötig ist und damit eine Sicherheit vor Auslesen des persönlichen Öffnungscodes bietet und darüber hinaus eine schnelle und komfortable Verwaltung der Schlossvorrichtung gewährleistet, wenn die Nutzer häufig wechseln.Based on the above-described prior art, the present invention seeks to provide a lock device that is reset in factory settings and in the retrieval of a lost opening code is neither possible nor necessary and thus provides security against reading the personal opening code and about In addition, a quick and comfortable management of the lock device ensures when users change frequently.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Zurücksetzen des Kombinationsschlosses in einen Zustand mit vorgegebenen Öffnungscode automatisch erfolgt, wenn das Sekundärschloss betätigt ist und während der Öffnungsdrehbewegung der Schlossvorrichtung durch gleichzeitiges Betätigen eines Betätigungselementes die Kupplungsscheiben aus den Stellrädern ausgekuppelt sind.The object is achieved in that the resetting of the combination lock automatically takes place in a state with predetermined opening code, when the secondary lock is actuated and during the opening rotation of the lock device by simultaneous actuation of an actuating element, the clutch discs are disengaged from the setting wheels.
Gemäß einer vorteilhaften Ausführungsform der erfindungsgemäßen Schlossvorrichtung verfügen die Stellräder des Kombinationsschlosses über koaxial angeordnete Kupplungsscheiben, die in verschiedenen Winkelpositionen mit den Stellrädern drehfest eingekuppelt oder ausgekuppelt werden können, und die auf einer äußeren Umfangsfläche Taschen aufweisen, in die die Tastelemente eines Abtastteils fallen können.According to an advantageous embodiment of the lock device according to the invention, the adjusting wheels of the combination lock on coaxially arranged clutch discs, which can be rotatably engaged or disengaged in different angular positions with the setting wheels, and having pockets on an outer peripheral surface into which the sensing elements of a sensing part can fall.
An den Stellrädern und Kupplungsscheiben sind bevorzugt jeweils Stellelemente ausgebildet, mittels deren die Stellräder und Kupplungsscheiben durch ein Einstellteil in eine vorgebbare Winkelstellung gedreht werden können, wenn Einstellabschnitte eines Einstellteils auf die Stellelemente wirken, wobei die vorgebbare Winkelstellung vorzugsweise dem werksseitig voreingestellten Öffnungscode entspricht.On the adjusting wheels and clutch plates are preferably each adjusting elements formed by means of which the adjusting wheels and clutch discs can be rotated by a setting in a predetermined angular position when adjusting sections of an adjustment act on the control elements, wherein the predetermined angular position preferably corresponds to the factory preset opening code.
Die stellradseitigen- und kupplungsscheibenseitigen Stellelemente sind vorteilhaft so gestaltet, dass sie spiralförmig auf die Drehachse zulaufende Kurvenabschnitte sind, die, wenn sie von Einstellabschnitten des betätigten Einstellteils in Richtung der Drehachse beaufschlagt werden, die Stell- bzw. Kupplungsscheiben in eine vorgebbare Winkelstellung drehen.The Stellradseitige- and clutch plate side adjusting elements are advantageously designed so that they are spirally tapering on the axis of rotation curve portions which, when acted on by adjustment of the actuated adjusting member in the direction of the axis of rotation, the adjusting or coupling discs rotate in a predetermined angular position.
In Weiterbildung der Erfindung ist am Einstellteil, das drehbar um eine Achse gelagerte ist, die parallel zu einer die Stellräder und Kupplungsscheiben lagernden Achse angeordnet, sind erste Einstellabschnitte ausgebildet, die den Stellelementen der Stellräder zugeordnet sind und zweite Einstellabschnitte, die den Stellelementen der Kupplungsscheiben zugeordnet sind, wobei die ersten Einstellabschnitte so angeordnet sind, dass sie bei jeder Betätigung des Einstellteils auf die Stellelemente der Stellräder wirken und die zweiten Einstellabschnitte so angeordnet sind, dass sie nur dann auf die Stellelemente der Kupplungsscheiben wirken, wenn sich die Kupplungsscheiben in einer mit den Stellrädern ausgekuppelten Position befinden.In a further development of the invention is arranged on the adjusting member which is rotatably mounted about an axis which is parallel to a bearing the adjusting wheels and clutch discs axis, first Einstellabschnitte are formed, which are associated with the control elements of the adjusting wheels and second adjusting sections associated with the control elements of the clutch discs are, wherein the first adjusting portions are arranged so that they act on each actuation of the adjusting member on the adjusting elements of the adjusting wheels and the second adjusting portions are arranged so that they act on the adjusting elements of the clutch discs only when the clutch discs in one with the Adjusting wheels are disengaged position.
Das Einstellteil wird bei jeder Öffnungsdrehbewegung der Schlossvorrichtung betätigt. In einer mit den Stellrädern eingekuppelten Position der Kupplungsscheiben, werden entsprechend nur die Stellräder in ihre vorgebbare Stellung gedreht. Die drehfest eingekuppelten Kupplungsscheiben werden dabei, ohne ihre relative Position zum Stellrad zu ändern, mitgenommen, so dass der eingestellte Öffnungscode erhalten bleibt und das Verwischen des angezeigten Öffnungscodes gewährleistet ist.The adjusting member is operated every opening rotation of the lock apparatus. In a coupled with the setting wheels position of the clutch discs, only the adjusting wheels are rotated according to their predetermined position accordingly. The rotatably engaged clutch plates are thereby, without changing their relative position to the setting wheel, taken away, so that the set opening code is maintained and the blurring of the displayed opening code is guaranteed.
In einer mit den Stellrädern ausgekuppelten Position der Kupplungsscheiben hingegen, werden die Stellräder als auch die Kupplungsscheiben unabhängig von einander in ihre jeweils vorgebbare Stellung gedreht. Der eingestellte Öffnungscode bleibt somit nicht erhalten und der werkseitig vorgegebene Öffnungscode wird eingestellt.In contrast, in a disengaged with the setting wheels position of the clutch discs, the adjusting wheels and the clutch discs are rotated independently of each other in their respective predeterminable position. The set opening code is thus not retained and the factory default opening code is set.
Des Weiteren verfügt die erfindungsgemäße Ausführungsform der Schlossvorrichtung über ein Abtastteil, das ebenfalls drehbar um eine Achse gelagert ist, die parallel zu einer die Stellräder und Kupplungsscheinen lagernden Achse angeordnet ist und darüber hinaus in Richtung der Achse verschiebbar ist. Das Abtastteil ist durch eine ersten Druckfeder in Drehrichtung auf die Kupplungsscheiben so vorgespannt, dass Tastelemente des Abtastteils an den äußeren Umfangsflächen der Kupplungsscheiben anliegen und in die Taschen der Umfangsflächen fallen, wenn sich die Taschen aller Kupplungsscheiben gegenüber den Tastelementen des Abtastteils befinden bzw. der Öffnungscode eingestellt ist.Furthermore, the embodiment of the lock device according to the invention has a scanning part, which is likewise rotatably mounted about an axis which is parallel to an axis supporting the adjusting wheels and coupling coupons is arranged and, moreover, is displaceable in the direction of the axis. The sensing member is biased by a first compression spring in the direction of rotation of the clutch discs so that sensing elements of the scanning abut the outer peripheral surfaces of the clutch discs and fall into the pockets of the peripheral surfaces when the pockets of all the clutch discs are opposite to the sensing elements of the Abtastteils or the opening code is set.
Bei eingestelltem Öffnungscode fallen die Tastelemente des Abtastteils in die Taschen der Kupplungsscheiben, wobei das Abtastteil eine kurze Kippbewegung um die eigene Achse ausführt, Dabei gibt der Hebelarm des Abtastteils einen mit der ersten Druckfeder vorgespannten und in einer Schieberplatte gelenkig gelagerten Riegel frei, so dass sich der Riegel in eine erste, die Schlossvorrichtung freigebende Stellung bewegt.When the opening code is set, the sensing elements of the scanning fall into the pockets of the clutch discs, wherein the scanning performs a short tilting movement about its own axis, this gives the lever arm of the Abtastteils a biased with the first compression spring and hinged in a slide plate latch so that the latch moves to a first position releasing the lock device.
Vorteilhaft weist das Abtastteil Mitnehmerstege auf, zwischen denen die in Achsrichtung aneinander liegenden Kupplungsscheiben formschlüssig so gefangen sind, dass sie sich zwar frei drehen können aber bei Verschiebung des Abtastteils in Achsrichtung mitgenommen werden. Das Abtastteil ist dabei mit einer zweiten Druckfeder in Achsrichtung so vorgespannt, dass im nicht betätigten Zustand des Abtastteils die Kupplungsscheiben in axialer Richtung in der mit den Stellrädern eingekuppelten Position gehalten werden und bei Betätigung des Abtastteils in Achsrichtung gegen die zweite Druckfeder die Kupplungsscheiben aus den Stellrädern ausgekuppelt werden.Advantageously, the sensing part on Mitnehmerstege, between which the adjacent in the axial direction of the clutch discs are positively caught so that they can indeed rotate freely but are taken along with displacement of the Abtastteils in the axial direction. The sensing part is biased with a second compression spring in the axial direction so that in the non-actuated state of the Abtastteils the clutch discs are held in the axial direction in the coupled with the setting wheels position and upon actuation of the Abtastteils in the axial direction against the second compression spring, the clutch discs from the setting wheels be disengaged.
Das Sekundärschloss der erfindungsgemäßen Schlossvorrichtung ist vorteilhaft als ein mit Hauptschlüssel zu bedienender Schließzylinder ausgebildet, welcher auf der der Schlüsselöffnung gegenüberliegenden Stirnseite einen exzentrisch angeordneten Mitnehmerzapfen aufweist, der bei Drehung in Entriegelungsrichtung eine quer zur Achse des Abtastteils verschiebbare Schieberplatte mitnimmt, und die wiederum einen an ihr gelenkig befestigten Riegel, unabhängig vom eingestellten Code, in eine die Schlossvorrichtung freigebende Position bewegt.The secondary lock of the lock device according to the invention is advantageously designed as a key-operated cylinder, which has an eccentrically arranged driving pin on the opposite end of the keyhole, which entrains a transverse to the axis of the Abtastteils sliding plate when rotating in the unlocking, and in turn one on her articulated latch, regardless of the set code, moves in a releasing the lock device position.
Des Weiteren verfügt die vorteilhafte Ausführung der erfindungsgemäßen Schlossvorrichtung über ein Blockierteil, das quer zur Schieberplattenrichtung aber parallel zur Achse des Abtastteils, in der Schieberplatte verschiebbar gelagert ist und bei nicht in Grundstellung befindlicher Schlossvorrichtung und nicht betätigtem Sekundärschloss, das Abtastteil in die Kupplungsscheiben auskuppelnde Richtung blockiert. Dadurch wird sichergestellt, dass die Kupplungsscheiben nicht durch unbeabsichtigtes Betätigen des seitlichen Betätigungselementes beim Öffnen bzw. Drehen der Schlossvorrichtung im Normalbetrieb ausgekuppelt werden.Furthermore, the advantageous embodiment of the lock device according to the invention has a blocking part, which is mounted transversely to the slide plate direction but parallel to the axis of the Abtastteils, slidably in the slide plate and blocked in non-home position lock device and non-actuated secondary lock, the scanning in auskuppelnde direction in the clutch discs , This ensures that the clutch discs are not disengaged by unintentional actuation of the lateral actuating element when opening or turning the lock device in normal operation.
Darüber hinaus ist es vorteilhaft das Schließwerk über einem in Bezug zum Schrank bzw. Behältnis feststehenden Stator anzuordnen, in dem Kurvenbahnen mit Vertiefungen und Erhebungen ausgebildet sind, durch die über Druckstifte die Funktionsbewegungen von Einstellteil, Abtastteil und Rastfeder während der Öffnungsdrehbewegung der Schlossvorrichtung gesteuert werden.Moreover, it is advantageous to arrange the locking mechanism over a stationary relative to the cabinet or container stator, are formed in the curved paths with depressions and elevations, are controlled by the pressure strokes, the functional movements of setting, Abtastteil and detent spring during the opening rotational movement of the lock device.

Der Stator 8, der seitliche Abflachungen 14 aufweist, ragt durch die ebenfalls mit seitlichen Abflachungen versehene Lochung 15 der angedeuteten Schranktür 16 und ist von hinten mit einer Befestigungsmutter 17 mit der angedeuteten Schranktür 16 starr verbunden. Der Stator 8 bildet somit mit der Befestigungsmutter 17, einem Sperrstück 18 und einer Schenkelfeder 19 eine in Bezug zur Schranktür feststehende Einheit der Schlossvorrichtung. Alle anderen Teile bilden zusammen mit dem Gehäuse 3 eine in Bezug zur Schranktür drehbare Einheit.The
Das Gehäuse 3 der hier beschriebenen Ausführungsform dient vorteilhaft als Bedienelement, das zum Öffnen und Schließen der Schlossvorrichtung wie ein Knauf gegriffen und gedreht werden kann.
Wird die Schlossvorrichtung über das Kombinationsschloss 1 oder dem Sekundärschloss 2 entriegelt, kann sie durch eine Öffnungsdrehbewegung in die, wie in

Dem Kombinationsschloss 1 zugeordnet ist die Achse 26, die im Gehäuse 3 fest gehaltert ist und auf der in dieser Ausführungsform vier Kupplungsscheiben 25 drehbar und axial verschiebbar gelagert sind. Jede Kupplungsscheibe 25 greift seitlich in ein Stellrad 4, das wiederum auf einem Hülsenabschnitt 27 der Kupplungsscheiben 25 drehbar gelagert ist und durch die Fenster 5 des Gehäuses 3 ragen, wo sie seitlich geführt sind.Associated with the
An dem Rasthebel 28, dessen Achse 29 parallel zur Achse 26 im Gehäuse 3 drehbar gelagert ist, sind Rastfedern 30 befestigt, die, wenn der Rasthebel 28 von einem Druckstift 31 beaufschlagt wird, auf die Stellräder 4 wirken und für einen Rasteffekt beim Drehen bzw. Einstellen der Stellräder 4 sorgen und diese exakt in der eingestellten Rastposition bzw. Codeeinstellung halten.On the locking
Der Abtasthebel 32 dessen Achse 33 ebenfalls parallel zur Achse 26 im Gehäuse 3 drehbar und axial verschiebbar gelagert ist, wird mittels der Druckfeder 34 in die Kupplungsscheiben 25 einkuppelnde Richtung vorgespannt. Der Abtasthebel 7 weist auf der der Druckfeder 34 gegenüber liegenden Seite ein Betätigungselement 6 auf, das durch die seitliche Öffnung 35 im Gehäuse 3 ragt. Des Weiteren weist der Abtasthebel 32 je einer Kupplungsscheibe 25 zugeordnete Tastarme 42 auf, an denen wiederum Tastelemente 43 ausgebildet sind, die auf die Umfangsflächen 44 der Kupplungsscheiben 25 mittels der Druckfeder 45 vorgespannt sind, wenn der Abtasthebel 7 nicht von dem Druckstift 46 beaufschlagt wird.The
Das Einstellteil 36, dessen Achse 37 ebenfalls parallel zur Achse 26 im Gehäuse 3 drehbar gelagert ist, weist Einstellabschnitte 38 und 70 auf, die, wenn das Einstellteil 36 von dem Druckstift 39 beaufschlagt wird, auf die Einstellabschnitte 40 der Stellräder 4 bzw. auf die Einstellabschnitte 41 der Kupplungsscheiben 25 wirken.The adjusting
Der Riegel 32 ist mit seinen gegenüberliegenden Gelenkzapfen 47 schwenkbar in den Lageraugen 48 der Schieberplatte 24 gelagert und greift im verriegelten Zustand der Schlossvorrichtung formschlüssig in die Riegeltasche 49 des Sperrstückes 18, wodurch eine Öffnungsdrehbewegung der Schlossvorrichtung verhindert ist.The
Das Blockierteil 50 ist in einer Führungsnut 51 der Schieberplatte 24 quer zur Schieberichtung der Schieberplatte 24 bzw. parallel zur Achse 33 des Abtastteils 7 verschiebbar gelagert und weist eine Mitnehmernase 52 auf, die von einer Schiebernase 53 des Abtastteils 7 mitgenommen wird, wenn das Abtastteil 7 durch Betätigen des Betätigungselementes 6 gegen die Druckfeder 34 verschoben wird.The blocking
Der Rotor 10, der mit seinem Mitnehmerzapfen 57 durch die Führungsbuchse 58 des Stators 8 ragt, ist mittels der Schrauben 13 fest in das Gehäuse 3 geschraubt und hält das gesamte Schließwerk in Position.

Die Mitnehmerstege 66 und 67 des Abtastteils 7 sind so gestaltet, dass die Kupplungsscheiben 25 grundsätzlich unabhängig von ihrer Winkelstellung, also auch bei unbekanntem Öffnungscode, aus den Stellrädern 4 ausgekuppelt werden können. Dabei muss aber sicherstellt sein, dass sich bei unbekanntem Code die Kupplungsscheiben 25 nur bei betätigtem Sekundärschloss 2 und nicht im Normalbetrieb aus den Stellrädern 4 auskuppeln lassen.

Die Druckstifte 31, 39 und 46 laufen senkrecht in den Kurvenbahnen 73, 74 und 75 des Stators 3, die konzentrisch um die Drehachse der Schlossvorrichtung verlaufen und jeweils buckelförmige Erhebungen 76 aufweisen. Die Druckstifte 31, 39 und 46, die in den Durchbrüchen 58 des Rotors 10 in Längsrichtung geführte sind, führen somit bei einer Öffnungsdrehbewegung der Schlossvorrichtung einen Längshub aus, wenn sie über eine der Erhebungen 76 laufen. Der Druckstift 46 wirkt dabei auf das Einstellteil 36, der Druckstift 31 auf den Hebelarm 77 des Rasthebels 28 und damit auf die Rastfedern 30 und der Druckstift 39 auf den Hebelarm 78 des Abtasthebels 7.The pressure pins 31, 39 and 46 run vertically in the cam tracks 73, 74 and 75 of the
