Description

Die Erfindung betrifft eine Steuerungseinheit für ein elektronisches Schloss, insbesondere für ein Türschloss eines Tresors, welche zur elektronischen Datenverarbeitung einer benutzerseitig eingebbaren digitalen Kennung ausgebildet ist, aufweisend ein Gehäuse und ein manuell betätigbares Stellglied zur Steuerung einer mit einer Schließeinrichtung des Schlosses verbundenen Welle, wobei das Stellglied in Abhängigkeit der Gültigkeit der eingegebenen Kennung aktivierbar ausgebildet ist. Ferner betrifft die Erfindung ein elektronisches Schloss mit einer Steuerungseinheit gemäß der Erfindung.The invention relates to a control unit for an electronic lock, in particular for a door lock of a safe, which is designed for electronic data processing of a digital identifier that can be entered by the user, having a housing and a manually operable actuator for controlling a shaft connected to a locking device of the lock, the Actuator is designed to be activated depending on the validity of the identifier entered. Furthermore, the invention relates to an electronic lock with a control unit according to the invention.

Vorgenannte Steuerungseinheiten dienen in erste Linie der Eingabe und der Verarbeitung einer insbesondere elektronischen Kennung, beispielsweise in Form einer Zahlenfolge. Die eingegebene Kennung wird mit einem Sollwert verglichen. Stimmen Kennung und Sollwert überein, ist die Kennung gültig. Erst bei Vorliegen einer gültigen Kennung wird das Stellglied aktiviert, so dass die mit der Schließeinrichtung verbundene Welle, insbesondere Antriebswelle, mittels des Stellglieds gesteuert werden kann. Durch die Welle wird die Schließeinrichtung zwischen den Stellungen "Offen" und "Geschlossen" bewegt. Eine Schließeinrichtung umfasst dabei meist Riegel, die je nach gewünschter Stellung ein- und ausgefahren werden können.The aforementioned control units are primarily used for inputting and processing an identifier, in particular an electronic identifier, for example in the form of a sequence of numbers. The identifier entered is compared with a target value. If the identifier and setpoint match, the identifier is valid. The actuator is activated only when a valid identifier is present, so that the shaft connected to the locking device, in particular the drive shaft, can be controlled by the actuator. The locking device is moved between the "open" and "closed" positions by the shaft. A locking device usually includes bolts that can be moved in and out depending on the desired position.

Die Steuerung der Welle durch das Stellglied kann dabei unmittelbar im Sinne einer mechanischen Bewegungskoppelung erfolgen. Alternativ kann die Steuerung mittelbar erfolgen, indem mittels des Stellglieds ein mit der Welle verbundener Antriebsmotor bestromt wird. In diesem Fall wirkt das Stellglied beispielsweise als elektrischer Schalter, mittels dem der Versorgungsstromkreis des Antriebsmotors unterbrochen oder geschlossen wird.The shaft can be controlled directly by the actuator in the sense of a mechanical movement coupling. Alternatively, the control can take place indirectly, in that a drive motor connected to the shaft is energized by means of the actuator. In this case, the actuator acts, for example, as an electrical switch, by means of which the power supply circuit of the drive motor is interrupted or closed.

Steuerungseinheiten mit Stellglied aufweisend eine Handhabe, beispielsweise in Form eines Griffes oder eines Hebels, sind aus dem Stand der Technik gut bekannt. Ein gesonderter druckschriftlicher Nachweis erübrigt sich daher an dieser Stelle.Control units with an actuator having a handle, for example in the form of a handle or a lever, are well known in the art. A separate printed proof is therefore not necessary at this point.

Diese bekannten Ausgestaltungen sind in meist in Form eines hervorstehenden Türgriffes oder eines Drehgriffes realisiert. Beide Ausgestaltungen sind jedoch anfällig für bestimmte Fehlfunktionen, die einen erhöhten Reparatur und Wartungsaufwand erfordern. Aufgrund der jeweiligen Mechanismen neigen beide Ausgestaltungen dazu, sich zu verkannten und mit der Zeit zu zerkratzen. Die Schrift DE 10 2014 006515 A1 offenbart ebenfalls eine gattungsgemäße Steuerungseinheit.These known configurations are usually implemented in the form of a protruding door handle or a rotary handle. However, both configurations are susceptible to certain Malfunctions that require increased repair and maintenance effort. Due to their respective mechanisms, both designs tend to become misaligned and scratched over time. The font DE 10 2014 006515 A1 also discloses a generic control unit.

Es ist daher die Aufgabe der Erfindung diesbezüglich Abhilfe zu schaffen und insbesondere eine ergonomisch handhabbare und ferner auch gegen unberechtigten Zugriff sichere Steuerungseinheit bereitzustellen.It is therefore the object of the invention to provide a remedy in this regard and in particular to provide a control unit which can be handled ergonomically and is also secure against unauthorized access.

Zur Lösung der Aufgabe wird mit der Erfindung eine Steuerungseinheit gemäß Anspruch 1 vorgeschlagen.To solve the problem, a control unit according to claim 1 is proposed with the invention.

Die erfindungsgemäße Ausgestaltung ist gegenüber den aus dem Stand der Technik bekannten Ausgestaltungen verklemmsicher ausgebildet. Zum anderen ist die Handhabe gegenüber unbeabsichtigter, schadhafter Einwirkung vergleichsweise gut geschützt. Dies insbesondere deshalb, sie am Außenrand der des Gehäuses entlanggeführt wird und entsprechend positioniert ist. Sie ist daher durch den Gehäuserand vor den Einwirkungen geschützt. Darüber hinaus erlaubt die erfindungsgemäße Ausgestaltung die Handhabe vergleichsweise klein auszubilden. Die Angriffsfläche für Fremdeinwirkung ist damit deutlich reduzierter als die aus dem Stand der Technik bekannten Lösungen, so dass eine höhere Sicherheit gegen unbefugten Zugriff möglich ist.The configuration according to the invention is designed to be safe from jamming compared to the configurations known from the prior art. On the other hand, the handle is comparatively well protected against unintentional, damaging effects. This in particular because it is guided along the outer edge of the housing and is positioned accordingly. It is therefore protected from the effects by the edge of the housing. In addition, the configuration according to the invention allows the handle to be made comparatively small. The attack surface for external influences is thus significantly smaller than the solutions known from the prior art, so that greater security against unauthorized access is possible.

Erfindungsgemäß weist das Stellglied eine Scheibe auf, welche innerhalb des Gehäuses um eine zentrale Achse rotierbar gelagert ist. Eine Scheibe im Sinne der Erfindung bezeichnet einen geometrischen Körper in Form eines Zylinders, dessen Radius um ein Vielfaches höher ist als seine Dicke. In axialer Aufsicht hat die Scheibe vorzugsweise eine im Wesentlichen kreisförmige Kontur. Vorzugsweise sind die Scheibe und der kreisbogenförmige Außenrandabschnitt des Gehäuses mit korrespondierendem Radius ausgebildet. "Korrespondierend" bezeichnet im Sinne der Erfindung einen gleichen Wert oder einen um bis zu +/- 10 % abweichenden Wert. Vorzugsweise ist der Radius der Scheibe um maximal 5% geringer als der des kreisbogenförmigen Außenrandabschnitts des Gehäuses. In Vorteilhafter Weise befindet sich die Scheibe hierbei wenigstens zum überwiegenden Teil innerhalb des Gehäuses und ist dadurch vor Fremdeinwirkung geschützt. Darüber hinaus erlaub diese Ausgestaltung die Bewegung der Handhabe des Stellglieds entlang des Außenrandabschnitts des Gehäuses.According to the invention, the actuator has a disc which is mounted within the housing so that it can rotate about a central axis. A disc in the sense of the invention refers to a geometric body in the form of a cylinder whose radius is many times greater than its thickness. In an axial plan view, the disc preferably has a substantially circular contour. Preferably, the disc and the arcuate outer edge portion of the housing are formed with a corresponding radius. "Corresponding" in the context of the invention denotes an identical value or a value deviating by up to +/-10%. Preferably, the radius of the disc is less than that of the arcuate outer edge portion of the housing by a maximum of 5%. Advantageously, the disc is here at least for the most part within the housing and is thus protected from external influences. In addition, this configuration allows the handle of the actuator to be moved along the outer edge portion of the housing.

Erfindungsgemäß ist die Scheibe über einen Verbindungsabschnitt mit der Handhabe verbunden. Vorzugsweise ist der Verbindungsabschnitt umfangsseitig der Scheibe an selbiger befestigt. Es kann ferner vorgesehen sein, Scheibe und Verbindungsabschnitt einstückig auszubilden. Erfindungsgemäß ist der Verbindungsabschnitt nach Art eines flächigen Vorsprungs, insbesondere einer Zunge, ausgebildet. Andernendseitig ist der Verbindungsabschnitt mit der Handhabe verbunden. Die Handhabe ist vorzugsweise vollständig außerhalb des Gehäuses angeordnet. Der Verbindungsabschnitt ragt dazu aus dem Gehäuse heraus. Hierzu stellt der kreisbogenförmige Außenrandabschnitt des Gehäuses eine in Umfangsrichtung verlaufende Öffnung bereit, in welcher der Verbindungsabschnitt des Stellglieds geführt ist. Die Öffnung ist vorzugsweise als länglicher Schlitz in der Außenwand des Gehäuses im kreisbogenförmigen Außenrandabschnitt ausgebildet. Vorzugsweise erstreckt sich der Schlitz über den gesamten kreisbogenförmigen Abschnitt. Gemäß einem weiteren bevorzugten Merkmal ist der Außenrand der Scheibe mit dem Schlitz fluchtend angeordnet ist. Hierdurch ist ein weitgehender Verklemmschutz realisiert. Dies wird insbesondere durch den weitgehenden Verzicht auf zwischengeordnete bewegliche Teile erreicht. Für die Rotation des Stellglieds ist erfindungsgemäß lediglich eine Krafteinwirkung auf die Handhabe erforderlich, welche eine tangentiale, zur Rotation führende Kraft auf die Scheibe überträgt.According to the invention, the disc is connected to the handle via a connecting section. The connecting section is preferably fastened to the disk on the peripheral side thereof. Provision can also be made for the disk and connecting section to be designed in one piece. According to the invention, the connecting section is designed in the manner of a flat projection, in particular a tongue. The connecting section is connected to the handle at the other end. The handle is preferably arranged entirely outside the housing. For this purpose, the connecting section projects out of the housing. For this purpose, the arcuate outer edge section of the housing provides an opening running in the circumferential direction, in which the connecting section of the actuator is guided. The opening is preferably formed as an elongated slot in the outer wall of the housing in the arcuate outer edge portion. The slot preferably extends over the entire arcuate section. According to another preferred feature, the outer edge of the disk is aligned with the slot. As a result, extensive protection against jamming is implemented. This is achieved in particular by largely dispensing with intermediate moving parts. For the rotation of the actuator, according to the invention, only a force action on the handle is required, which transmits a tangential force leading to the rotation to the disk.

Gemäß einem bevorzugten Merkmal der Erfindung ist es vorgesehen, dass die Scheibe eine zentrale Ausnehmung zur Aufnahme der Welle der Schließeinrichtung aufweist. Welle und Scheibe sind insofern bestimmungsgemäß koaxial anordenbar bzw. angeordnet. Diese Ausgestaltung dient insbesondere der mechanischen Bewegungskoppelung zwischen Stellglied und Welle. Es sind jedoch auch elektronische Ausgestaltungen denkbar, in denen das Stellglied als elektrischer Schalter zur Bestromung eines Antriebsmotors dient.According to a preferred feature of the invention, it is provided that the disc has a central recess for receiving the shaft of the locking device. Shaft and disk can be or are arranged coaxially as intended. This configuration is used in particular for the mechanical movement coupling between the actuator and the shaft. However, electronic configurations are also conceivable, in which the actuator serves as an electrical switch for energizing a drive motor.

Es ist gemäß einem bevorzugten Merkmal der Erfindung vorgesehen, dass die Scheibe ein sich in Rotationsrichtung erstreckendes Langloch aufweist. Das Langloch dient der Festlegung zweier Endstellungen zwischen denen die Handhabe bewegt werden kann. Hierzu greift ein vorzugsweise zylindrischer Vorsprung des Getriebes in das Langloch ein. Die Rotationsbewegung der Scheibe ist dabei durch das Erreichen der jeweiligen Endstellung begrenzt, bei der der Vorsprung die jeweilige endseitige Wand des Langlochs kontaktiert. Vorzugsweise definiert die eine Endstellung dabei den Zustand "Offen" und die andere Endstellung den Zustand "Geschlossen". Bei Erreichen der jeweiligen Endstellung überträgt die Welle die Rotation des Stellgliedes derart auf die Schließeinrichtung, dass sich dieser in entsprechender Stellung befindet. Dies kann vorzugsweise mittels eines seitens der Schließeinrichtung vorgesehenen Getriebes zur Umwandlung der Rotationsbewegung der Welle erfolgen. Vorzugsweise weist das Langloch wenigstens einendseitig eine Lochverbreiterung zur Festlegung der Endstellungen des Stellglieds auf. Diese kann in Entsprechung der Kontur des Gehäusevorsprungs eckig oder rund ausgebildet sein. Vorzugsweise ist die Lochverbreiterung elliptisch ausgebildet. Vorzugsweise steht der Vorsprung unter Federvorspannung. Bei Erreichen der jeweiligen Endstellung wird der Vorsprung durch die anliegende Federkraft in die Lochverbreiterung gedrückt. Hierdurch ist eine eindeutige Endstellung definiert.It is provided according to a preferred feature of the invention that the disc has a slot extending in the direction of rotation. The slot is used to define two end positions between which the handle can be moved. For this purpose, a preferably cylindrical projection of the gear engages in the elongated hole. The rotational movement of the disk is limited by reaching the respective end position in which the projection contacts the respective end wall of the elongated hole. One end position preferably defines the “open” state and the other end position defines the “closed” state. When the respective end position is reached, the shaft transmits the rotation of the actuator to the locking device in such a way that it is in the corresponding position. This can preferably be done by means of a gear provided by the locking device for converting the rotational movement of the shaft. The elongated hole preferably has a hole widening at least at one end for fixing the end positions of the actuator. This can be angular or round in accordance with the contour of the housing projection. Preferably, the hole widening is elliptical. The projection is preferably spring-biased. When the respective end position is reached, the projection is pressed into the widened hole by the applied spring force. This defines a clear end position.

Es ist bevorzugt vorgesehen, dass das Langloch in radialer Richtung beabstandet von der zentralen Ausnehmung angeordnet ist. Das Langloch umgreift dabei die zentrale Ausnehmung dabei in Rotationsrichtung teilweise. Dies dient dem Zwecke der räumlichen Separation von Vorsprung und Welle. Vorteilhafterweise werden hierdurch Beschädigungen an den Bauteilen vermieden.Provision is preferably made for the elongated hole to be arranged at a distance from the central recess in the radial direction. The elongated hole partially encompasses the central recess in the direction of rotation. This serves the purpose of spatially separating the projection and shaft. This advantageously prevents damage to the components.

Gemäß einem weiteren bevorzugten Merkmal der Erfindung ist vorgesehen, dass die Scheibe ein sich in radialer Richtung erstreckendes Langloch aufweist. Dieses Langloch dient zum einen der Montage eines radial zu einer Welle verlaufenden Eingriffselement, welches sich von der Welle in das Langloch erstreckt. Die Welle verbindet die Scheibe des Stellglieds mit dem Schließmechanismus. Das Eingriffselement kann beispielsweise als zylindrischer Stift ausgebildet und in eine Radialbohrung der Welle eingesetzt sein. Entspricht der Durchmesser des Stiftes der Innenabmessung des einseitig offen ausgebildeten Langlochs, so wird eine Drehbewegung der Scheibe unmittelbar über den Stift auf die Welle übertragen. Das Langloch dient somit zum anderen der Verbindung zwischen Stellglied und Schließmechanismus. Die Verbindung zwischen der Scheibe des Stellglieds und der in den Schließmechanismus eingreifenden Welle ist in diesem Fall formschlüssig ausgebildet. Vorzugsweise ist das Langloch kürzer ausgebildet als der Stift, so dass die Montage des Stiftes in der Welle vereinfacht ist.According to a further preferred feature of the invention, it is provided that the disc has an elongated hole extending in the radial direction. On the one hand, this elongated hole serves to mount an engagement element which runs radially to a shaft and which extends from the shaft into the elongated hole. The shaft connects the actuator disc to the locking mechanism. The engagement element can be designed, for example, as a cylindrical pin and can be inserted into a radial bore of the shaft. If the diameter of the pin corresponds to the inner dimension of the elongated hole that is open on one side, a rotational movement of the disc is transmitted directly to the shaft via the pin. The elongated hole thus serves on the other hand for the connection between the actuator and the locking mechanism. The connection between the disc of In this case, the actuator and the shaft engaging in the locking mechanism are formed in a form-fitting manner. The elongated hole is preferably shorter than the pin, so that the assembly of the pin in the shaft is simplified.

Die Erfindung betrifft ferner ein elektronisches Schloss, insbesondere Türschloss eines Tresors, mit einer Steuerungseinheit gemäß der Erfindung, einer in eine Tür einbaubaren Schließeinrichtung und einer Welle, welche Steuerungseinheit und Schließeinrichtung miteinander verbindet.The invention also relates to an electronic lock, in particular a door lock of a safe, with a control unit according to the invention, a locking device that can be installed in a door, and a shaft that connects the control unit and the locking device to one another.

Insgesamt werden durch die Erfindung eine Steuerungseinheit und ein elektronisches Schloss bereitgestellt, bei dem die Handhabe verklemmsicher betätigbar und gegenüber Verkratzung weitestgehend geschützt ist.Overall, the invention provides a control unit and an electronic lock in which the handle can be actuated in a jam-proof manner and is largely protected against scratching.

Figuren 1 und 2 zeigen die erfindungsgemäße Steuerungseinheit 1 in Ansicht von vorne bzw. seitlich von vorne. Zu erkennen ist das Gehäuse 2, welches frontseitig ein Bedienfeld 3 zur Eingabe einer zahlen- und/oder buchstabenbasierten Kennung aufweist. figures 1 and 2 show the control unit 1 according to the invention in a view from the front and side from the front. The housing 2 can be seen, which has a control panel 3 on the front for entering a numerical and/or letter-based identifier.

Ferner verfügt das Gehäuse 2 über ein Funksymbol 4, hinter dem ein Funkempfänger, insbesondere zum Empfang eines WLAN-, Bluetooth- oder NFC-Signals, angeordnet ist. Es ist vorgesehen, dass die elektronische Kennung zusätzlich oder alternativ zur Eingabe über das Bedienfeld 3 über einen externen Sender, insbesondere ein Smartphone oder ein Tablet, übermittelt und weiterverarbeitet wird.Furthermore, the housing 2 has a radio symbol 4 behind which a radio receiver, in particular for receiving a WLAN, Bluetooth or NFC signal, is arranged. Provision is made for the electronic identifier to be transmitted and further processed via an external transmitter, in particular a smartphone or a tablet, in addition to or as an alternative to input via the control panel 3 .

Darüber hinaus verfügt die Steuerungseinheit 1 frontseitig des Gehäuses 2 über einen Sensor 5 zur Erfassung biometrischer Daten. Diese biometrischen Daten können ebenfalls als Kennung im Sinne der Erfindung verarbeitet werden. Biometrische Daten sind dabei vorzugsweise fingerabdruck-, gesichts- und/oder netzhautbezogene Daten eines Benutzers.In addition, the control unit 1 has a sensor 5 on the front of the housing 2 for recording biometric data. This biometric data can also be processed as an identifier within the meaning of the invention. Biometric data are preferably fingerprint, facial and/or retina-related data of a user.

Die über das Bedienfeld 3, die Funkverbindung und/oder über den Sensor erhaltenen Kennungen können in Kombination miteinander abgeglichen und mit einem vorgebbaren Sollwert verglichen werden. Nur wenn alle drei Werte mit dem Sollwert übereinstimmen liegt beispielsweise ein gültiger Zustand vor, der die Aktivierung eines Stellglieds 6 erlaubt. Hierdurch wird die Sicherheit des Schlosses insgesamt verbessert.The identifiers obtained via the control panel 3, the radio link and/or via the sensor can be compared with one another in combination and compared with a predefinable target value. For example, only if all three values match the desired value is there a valid state that allows an actuator 6 to be activated. This improves the overall security of the lock.

Die Steuerungseinheit 1 weist frontseitig des Gehäuses 2 ein Display 7 auf. Hierüber können dem Benutzer bestimmte Zustände der Steuerung angezeigt und Anweisungen gegeben werden. vorzugsweise handelt es sich hierbei um ein LCD-Display oder ein OLED-Display.The control unit 1 has a display 7 on the front side of the housing 2 . This can be used to show the user certain statuses of the controller and give instructions. this is preferably an LCD display or an OLED display.

Das Display 7 und der Sensor 5 sind in einem Flächenbereich angeordnet, der unter einem Winkel zu einer Rückseite des Gehäuses 2 derart angeordnet ist, dass die Darstellungen auf dem Display 7 bzw. die Nutzung des Sensors 5 ergonomisch optimiert ist. Hierdurch wird eine gute Ablesbarkeit des Displays 7 bereitgestellt und die Nutzung des Sensors 5 ist mit einer für den Benutzer angenehmen Bewegung beispielsweise seiner Hand mit ausgestrecktem und zur Legitimation erforderlichen Finger verbunden. Durch die Anordnung dieser Baugruppen in diesem Flächenbereich ist die Handhabung dieser Baugruppen auch selbsterklärend, so dass auch Benutzer mit geringen Kenntnissen über derartige Steuerungseinheiten schnell mit einer Handhabung vertraut sind.The display 7 and the sensor 5 are arranged in a surface area which is arranged at an angle to a rear side of the housing 2 in such a way that the representations on the display 7 and the use of the sensor 5 are ergonomically optimized. This provides good readability of the display 7 and the use of the sensor 5 is connected to a movement that is comfortable for the user, for example his hand with an outstretched finger and is required for legitimation. Due to the arrangement of these assemblies in this area, the handling of these assemblies is also self-explanatory, so that even users with little knowledge of such control units are quickly familiar with handling.

Ferner verfügt die Steuerungseinheit 1 seitlich des Gehäuses 2 über ein in den Figuren 6 und 7 im Detail dargestelltes Stellglied 6. Das Stellglied 6 weist eine rotierbar innerhalb des Gehäuses 2 gelagerte Scheibe 9 und eine über einen Verbindungsabschnitt 10 mit selbiger verbundene Handhabe 11 auf. Bestimmungsgemäß sind die Handhabe 11 und der Verbindungsabschnitt 10 entlang eines kreisbogenförmigen Außenrandabschnitts 12 des Gehäuses 2 bewegbar. Dies wird vorliegend dadurch realisiert, dass der Radius der Scheibe 9 identisch mit dem Radius des kreisbogenförmigen Abschnitts 12 des Gehäuses 2 ausgebildet ist. Die Scheibe 9 ist insofern bündig mit den Außenwänden des Gehäuses 2 in einem vom Gehäuse 2 bereitgestellten Schlitz 13 angeordnet. Der Schlitz 13 erstreckt sich entlang des gesamten kreisbogenförmigen Abschnitts 12, welcher vorliegend die Unterseite des Gehäuses 2 bildet.Furthermore, the control unit 1 has a side of the housing 2 in the figures 6 and 7 actuator 6 shown in detail. The actuator 6 has a rotatably mounted disk 9 within the housing 2 and a handle 11 connected to the same via a connecting section 10 . The handle 11 and the connecting section 10 are intended to be movable along an arcuate outer edge section 12 of the housing 2 . In the present case, this is realized in that the radius of the disc 9 is identical to the radius of the arcuate section 12 of the housing 2 . In this respect, the disk 9 is arranged flush with the outer walls of the housing 2 in a slot 13 provided by the housing 2 . The slot 13 extends along the entire arcuate section 12, which forms the underside of the housing 2 in the present case.

Die Handhabe 11 ist zweiteilig ausgebildet, wobei die beiden Teile 14, 15 (Figur 1) beidseits des Verbindungsabschnitts 10 mit diesem verbunden, vorzugsweise verschraubt sind. Beide Teile 14, 15 weisen gehäuseseitig eine gerade Außenfläche auf. Eine gehäuseentfernte Außenfläche ist demgegenüber abgerundet ausgebildet. Dabei weisen diese Außenflächen einen im Wesentlichen halbkreisförmigen Querschnitt auf. Beide Teile 14, 15 sind nach Art eines einseitig offenen Hohlkörpers ausgebildet.The handle 11 is formed in two parts, the two parts 14, 15 ( figure 1 ) connected to both sides of the connecting portion 10 with this, preferably screwed. Both parts 14, 15 have a straight outer surface on the housing side. In contrast, an outer surface remote from the housing is rounded. In this case, these outer surfaces have an essentially semicircular cross section. Both parts 14, 15 are designed in the manner of a hollow body open on one side.

Zu erkennen ist ferner eine Batteriefachklappe 16, die eine Batterieaufnahme 17 verschließt.A battery compartment flap 16 which closes a battery receptacle 17 can also be seen.

Die Figuren 3 und 4 zeigen die Steuerungseinheit 1 in rückwärtiger Ansicht. Zu erkennen ist, dass das Gehäuse 2 zwei Gehäuseteile 18, 19 aufweist, zwischen denen der Schlitz 13 ausgebildet ist. Die beiden Gehäuseteile 18, 19 sind mittels der Schrauben 21, 22, 23 miteinander verbunden.The Figures 3 and 4 show the control unit 1 in rear view. It can be seen that the housing 2 has two housing parts 18, 19, between which the slot 13 is formed. The two housing parts 18, 19 are connected to one another by means of screws 21, 22, 23.

Ferner zu erkennen ist das Batteriefach 17, in welchem Batterien 20 angeordnet sind. Die Batterien 20 dienen der Stromversorgung der Steuerungseinheit 1. Das Batteriefach 17 ist mittels der Batteriefachklappe 16 unterseitig verschlossen. Die Klappe 16 bildet dabei einen Teil des kreisbogenförmigen Außenrandabschnitts 12 des Gehäuses 2. Sie verfügt zur Fixierung am Gehäuse 2 beidendseitig über Rastabschnitte 24.The battery compartment 17, in which batteries 20 are arranged, can also be seen. The batteries 20 are used to power the control unit 1. The battery compartment 17 is closed by means of the battery compartment flap 16 on the underside. The flap 16 forms part of the arcuate outer edge section 12 of the housing 2. It has latching sections 24 on both sides for fixing to the housing 2.

Figur 5 zeigt die Steuerungseinheit 1 in unterseitiger Ansicht. Besonders hervorgehoben ist die Batteriefachklappe 16. Sie ist zur weitergehenden Befestigung am Gehäuse 2 mittels einer Schraube 25 mit dem Gehäuse 2 verbunden. figure 5 shows the control unit 1 in a view from below. The battery compartment flap 16 is particularly emphasized. It is connected to the housing 2 by means of a screw 25 for further attachment to the housing 2 .

Die Figur 6 zeigt das Stellglied 6 in perspektivischer Ansicht von vorne. Das Stellglied 6 weist die Handhabe 11, den Verbindungsabschnitt 10 und die Scheibe 9 auf. Die Scheibe 9 weist ein in Rotationsrichtung verlaufendes erstes Langloch 26 auf. In dem kreisbogenabschnittförmig ausgebildeten Langloch 26 ist bestimmungsgemäß ein nicht gezeigter Vorsprung angeordnet. Bei einer Rotationsbewegung der Scheibe 9 bewegt sich das Langloch 26 relativ zu dem Vorsprung. Sobald der Vorsprung dabei in Kontakt mit den jeweiligen Enden 27, 28 des Langlochs 26 kommt, wird die Rotationsbewegung beendet, so dass zwei Endstellungen definiert sind. Die Enden 27, 28 sind als Lochverbreiterung ausgeführt und weisen jeweils einen elliptischen Umriss auf.The figure 6 shows the actuator 6 in a perspective view from the front. The actuator 6 has the handle 11, the connecting section 10 and the disc 9. The disk 9 has a first elongated hole 26 running in the direction of rotation. In accordance with regulations, a projection (not shown) is arranged in the oblong hole 26, which is designed in the shape of a segment of a circular arc. When the disk 9 rotates, the elongated hole 26 moves relative to the projection. As soon as the projection comes into contact with the respective ends 27, 28 of the elongated hole 26, the rotational movement is terminated, so that two end positions are defined. The ends 27, 28 are designed as hole widening and each have an elliptical outline.

Ferner weist die Scheibe 9 eine Zentrale Ausnehmung 29 auf. Die Ausnehmung 29 dient der Aufnahme einer Antriebswelle 31, welche die Steuerungseinheit 1, nämlich das Stellglied 6 bewegungstechnisch mit einer nicht dargestellten Schließeinrichtung verbindet.Furthermore, the disk 9 has a central recess 29 . The recess 29 serves to accommodate a drive shaft 31, which connects the control unit 1, namely the actuator 6, in terms of movement with a locking device, not shown.

Das Stellglied 6 weist ferner ein zweites Langloch 30 auf, welches sich in radialer Richtung der Scheibe 9 erstreckt und der Aufnahme eines Stiftes 32 dient, der zur Antriebswelle 31 radial verlaufend ausgerichtet ist und in eine Radialöffnung 33 der Antriebswelle 31 eingreift. Der Stift 32, der auch als Schraube oder Gewindestange ausgebildet sein kann, kann durch eine radial verlaufende und in einer Seitenfläche in Bereich des Langlochs 30 angeordnete Bohrung 34 der Scheibe 9 in diese Bohrung 34 eingeschoben und anschließend mit der Antriebswelle 31 verbunden werden. Hierbei erstreckt sich der Stift ausgehend von der Antriebswelle 31 in das Langloch 30.The actuator 6 also has a second elongated hole 30 which extends in the radial direction of the disk 9 and serves to receive a pin 32 which is aligned radially to the drive shaft 31 and engages in a radial opening 33 of the drive shaft 31 . The pin 32, which can also be designed as a screw or threaded rod, can be inserted through a radially running bore 34 of the disk 9 and arranged in a side surface in the area of the elongated hole 30 and then connected to the drive shaft 31. Here, the pin extends from the drive shaft 31 into the slot 30.

Abschließend zeigt Figur 8 eine ausschnittsweise Explosionsdarstellung der Steuerungseinheit 1, welche die Anordnung der einzelnen Elemente untereinander verdeutlicht. Die vorbeschriebenen Elemente der Erfindung sind auch in der Explosionsdarstellung mit gleichen Bezugszeichen bezeichnet wie in den übrigen Zeichnungen.Finally shows figure 8 a partial exploded view of the Control unit 1, which shows the arrangement of the individual elements with one another. The elements of the invention described above are also denoted in the exploded view with the same reference numbers as in the other drawings.

Die Figur 8 zeigt eine Folie 35, die auf dem Gehäuseteil 18 angeordnet ist. Die Folie 35 weist die Tasten des Bedienfelds 3 auf. Hierbei handelt es sich um Touchelemente, die für Berührungen sensitiv sind, so dass die Tasten keine mechanisch bewegbaren Bestandteile aufweisen. Hierdurch wird zum Beispiel auch vermieden, dass über eine Tastenbewegung ein Auslesen eines Schließgeheimnisses erfolgt. Die Folie 35 ist darüber hinaus im Bereich ihrer Oberfläche derart ausgebildet, dass Fingerabdrücke problemlos entfernt werden können. Hierzu kann die Oberfläche der Folie 35 lipophob ausgebildet sein.The figure 8 shows a foil 35 which is arranged on the housing part 18 . The film 35 has the buttons on the control panel 3 . These are touch elements that are sensitive to touch, so that the keys do not have any mechanically movable components. This also avoids, for example, a locking code being read out via a key movement. In addition, the film 35 is designed in the area of its surface in such a way that fingerprints can be removed without any problems. For this purpose, the surface of the film 35 can be designed to be lipophobic.

Insgesamt werden durch die Erfindung eine Steuerungseinheit und ein elektronisches Schloss bereitgestellt, bei dem die Handhabe verklemmsicher betätigbar und gegenüber Verkratzung weitestgehend geschützt ist.
