Description

Die Erfindung betrifft eine Entriegelungsvorrichtung für eine Tür oder ein Tor, mit einem Kraftübertragungsteil, das in Längsrichtung der Entriegelungsvorrichtung verstellbar ist und dabei auf ein Schloss wirken und dieses entriegeln kann, sowie einem Betätigungselement, das mittels mindestens einem Getriebe das Kraftübertragungsteil verstellen kann, und einem Antrieb, der das Kraftübertragungsteil verstellen kann, wobei der Antrieb einen Rotationsmotor und ein Antriebsgetriebe mit mindestens einem Rotationselement aufweist, und wobei das Antriebsgetriebe die rotatorische Bewegung des Rotationsmotors in eine lineare Bewegung des Kraftübertragungsteils übersetzt.The invention relates to an unlocking device for a door or a gate, with a power transmission part that can be adjusted in the longitudinal direction of the unlocking device and can act on a lock and unlock it, and an actuating element that can adjust the power transmission part by means of at least one gear, and a Drive that can adjust the power transmission part, the drive having a rotary motor and a drive gear with at least one rotary element, and the drive gear translating the rotary movement of the rotary motor into a linear movement of the power transmission part.

Solche Entriegelungsvorrichtungen sind bekannt und werden insbesondere an Türen eingesetzt, die Auflagen zur Entfluchtbarkeit eines Gebäudes genügen müssen. Die Entriegelungsvorrichtungen weisen üblicherweise ein längliches Gehäuse mit einer Druckstange als Betätigungselement auf, welches sich meist über die gesamte Breite der Tür oder des Tores erstreckt. Die Druckstange ist dabei über das Getriebe in das Gehäuse eindrückbar, um das Schloss mittels des Kraftübertragungsteils zu entriegeln. Dabei führt auch eine unkoordinierte Bewegung gegen die Tür mit der darauf angeordneten Entriegelungsvorrichtung, wie im Falle einer panischen Flucht, zum Entriegeln und Öffnen der Tür.Such unlocking devices are known and are used in particular on doors that have to meet requirements for escape from a building. The unlocking devices usually have an elongated housing with a push rod as an actuating element, which usually extends over the entire width of the door or gate. The push rod can be pressed into the housing via the gear in order to unlock the lock by means of the power transmission part. An uncoordinated movement against the door with the unlocking device arranged on it, as in the case of a panicked escape, also leads to the unlocking and opening of the door.

Bei Türen, an denen solche Entriegelungsvorrichtungen verbaut werden, muss oft auch eine automatische Entriegelung möglich sein. Dafür sind an der Tür Antriebe, etwa in einem Motorschloss, vorgesehen, um die Tür aus der Ferne zu entriegeln. So kann eine Tür, die auf der Gegenseite zur Entriegelungsvorrichtung keine weitere Entriegelungsvorrichtung, zum Beispiel einen Drücker, aufweist und somit manuell nicht ohne Schlüssel zu entriegeln ist, kurzzeitig für die Benutzung von dieser Seite aus freigegeben werden. Ein solches System ist etwa von Haustüren von Mehrfamilienhäusern bekannt und wird beispielsweise auch bei Eingangstüren von Veranstaltungsstätten eingesetzt.In the case of doors on which such unlocking devices are installed, automatic unlocking must often also be possible. For this purpose, drives are provided on the door, for example in a motor lock, in order to unlock the door remotely. So a door that is on the opposite side to the unlocking device no other unlocking device, for example a handle, and therefore cannot be unlocked manually without a key, can be released for use from this side for a short time. Such a system is known, for example, from the front doors of apartment buildings and is also used, for example, for the entrance doors of event venues.

Es sind solche Entriegelungsvorrichtungen mit einem integrierten Schloss bekannt, wobei dann kein Schloss in dem Türblatt selbst angeordnet ist und in Ausführungsformen, die mit einem in der Tür eingebauten Schloss zusammenwirken. Bei ersteren ist es bekannt, einen Antrieb in der Entriegelungsvorrichtung vorzusehen, der das Kraftübertragungsteil verstellen kann, wobei der Antrieb einen Rotationsmotor und ein Antriebsgetriebe mit mindestens einem Rotationselement aufweist, und wobei das Antriebsgetriebe die rotatorische Bewegung des Rotationsmotors in eine lineare Bewegung des Kraftübertragungsteils übersetzt. So etwa aus US 2011/0047874 A1 , US 4,976,479 und US 4,785,286 . Nachteilig sind diese sehr aufwändig gestaltet und benötigen viel Bauraum innerhalb der Entriegelungsvorrichtung.Such unlocking devices with an integrated lock are known, in which case no lock is arranged in the door leaf itself and in embodiments which interact with a lock built into the door. In the case of the former, it is known to provide a drive in the unlocking device which can adjust the force transmission part, the drive having a rotary motor and a drive gear with at least one rotary element, and the drive gear converting the rotary movement of the rotary motor into a linear movement of the force transmission part. Something like that US 2011/0047874 A1 , U.S. 4,976,479 and U.S. 4,785,286 . Disadvantageously, these are very complex and require a lot of space within the unlocking device.

Bei solchen Entriegelungsvorrichtungen, die mit einem Türschloss zusammenwirken, ist es bekannt, dass der automatische Antrieb schlossseitig umgesetzt wird und ein Motorschloss in die Tür eingebaut wird. Nachteilig sind dabei sowohl die Entriegelungsvorrichtung als auch das Motorschloss vergleichsweise teuer. Es ist grundsätzlich nachteilig, für jede gewünschte Funktion an der Tür, ein eigenes Funktionsbauteil vorzusehen. Soweit ein vorhandenes Schloss ohne Antrieb durch ein Motorschloss ersetzt werden soll, muss gegebenenfalls auch die Entriegelungsvorrichtung ersetzt werden. Gegebenenfalls müssen Entriegelungsvorrichtungen passend sowohl für normale Schlösser als auch für Motorschlösser vom Hersteller vorgehalten werden.With unlocking devices of this type, which interact with a door lock, it is known that the automatic drive is implemented on the lock side and a motor lock is installed in the door. The disadvantage here is that both the unlocking device and the motorized lock are comparatively expensive. It is fundamentally disadvantageous to provide a separate functional component for each desired function on the door. If an existing lock without a drive is to be replaced by a motor lock, the unlocking device may also have to be replaced. If necessary, unlocking devices suitable for both normal locks and motorized locks must be provided by the manufacturer.

Die Aufgabe der Erfindung ist es daher, eine Entriegelungsvorrichtung mit einem einfachen, kompakten Antrieb bereitzustellen.The object of the invention is therefore to provide an unlocking device with a simple, compact drive.

Gelöst wird die Aufgabe durch eine Entriegelungsvorrichtung nach Anspruch 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.The object is achieved by an unlocking device according to claim 1. Advantageous refinements are specified in the dependent claims.

Erfindungsgemäß weist das Antriebsgetriebe mindestens eine Pleuelstange auf, die auf das Kraftübertragungsteil wirkt und an einem Koppelpunkt verdrehbar an dem Rotationselement gelagert ist. Bei in der Entriegelungsvorrichtung angeordneten Antrieben ist der durch den Antrieb auf das Kraftübertragungsteil zur Entriegelung aufzubringende Kraftverlauf über den Entriegelungsvorgang nicht linear. Das Schloss wird üblicherweise gegen eine Rückstellfeder geöffnet, die einen progressiven Widerstand erzeugt. Zwischen dem Schloss und dem Kraftübertragungsteil ist zudem oft ein Getriebe angeordnet, das ebenfalls einen nichtlinearen Kraftverlauf bei der Umsetzung der linearen Bewegung des Kraftübertragungsteils in eine Drehbewegung eines Teils des Schlosses aufweist. Die gesamte Kraft, die von dem Kraftübertragungsteil auf das Schloss übertragen werden muss, ist daher in Summe ansteigend über den Entriegelungsvorgang.According to the invention, the drive gear has at least one connecting rod on, which acts on the power transmission part and is rotatably mounted at a coupling point on the rotary element. In the case of drives arranged in the unlocking device, the course of force to be applied by the drive to the force transmission part for unlocking is not linear over the unlocking process. The lock is usually opened against a return spring that creates progressive resistance. In addition, a gear is often arranged between the lock and the force transmission part, which also has a non-linear course of force when converting the linear movement of the force transmission part into a rotary movement of a part of the lock. The total force that has to be transmitted from the force transmission part to the lock is therefore increasing over the unlocking process.

Eine erfindungsgemäße Gestaltung kann eine derartig ansteigende Kraft bei gleichbleibender Belastung des Rotationsmotors mittels der Pleuelstange bereitstellen, denn deren Ausrichtung zum Kraftübertragungsteil bzw. der Winkel zwischen Längsachse der Pleuelstange und der Bewegungsachse des Kraftübertragungsteils verändert sich während der Entriegelung derart, dass sich die Übersetzung zwischen Rotationsmotor und Kraftübertragungsteil verändert. Die Rotationsachse des Rotationselements, an dem die Pleuelstange antriebsseitig angekoppelt ist, liegt orthogonal zur Bewegungsachse der linearen Bewegung des Kraftübertragungsteils, an dem das abtriebsseitige Ende der Pleuelstange angreift. Somit verändert sich während der Entriegelung der Stellwinkel zwischen der Verbindungslinie zwischen dem Mittelpunkt der Rotationselements und dem Koppelpunkt und der Bewegungsachse des Kraftübertragungsteils. Die Pleuelstange wird daher verschwenkt. In einer Ausgangsstellung kann der vorbeschriebene Stellwinkel etwa 90° betragen, von wo aus das Rotationselement zum Entriegeln bis zu einem Stellwinkel von 0° verdreht wird. Eine Verdrehung des Rotationselements um mehr als 90° ist dann nicht vorgesehen.A design according to the invention can provide such an increasing force with a constant load on the rotary motor by means of the connecting rod, because its alignment with the force transmission part or the angle between the longitudinal axis of the connecting rod and the axis of movement of the force transmission part changes during unlocking in such a way that the transmission ratio between the rotary motor and Power transmission part changed. The axis of rotation of the rotary element, to which the connecting rod is coupled on the input side, is orthogonal to the axis of movement of the linear movement of the power transmission part, on which the output-side end of the connecting rod engages. The setting angle between the connecting line between the center point of the rotary element and the coupling point and the axis of movement of the force transmission part thus changes during unlocking. The connecting rod is therefore pivoted. In an initial position, the above-described adjustment angle can be approximately 90°, from where the rotary element is rotated to an adjustment angle of 0° for unlocking. A rotation of the rotary element by more than 90° is then not provided.

Als Übersetzungsverhältnis wird das Verhältnis vK/ωR der Bewegungsgeschwindigkeit vK des Kraftübertragungsteils zu der Winkelgeschwindigkeit ωR des Rotationsteils verstanden, wenn sich die Teile in Bewegung befinden. Bei einem kleineren Übersetzungsverhältnis wird folglich bei gleicher Motorkraft eine größere Kraft auf das Kraftübertragungsteil erzeugt. Es kann somit vorteilhaft im Verlauf des Entriegelungsvorgangs eine größere Kraft auf das Kraftübertragungsteil bei gleichbleibender Motorleistung wirken. Der Rotationsmotor kann damit vorteilhaft klein ausgelegt, kompakt angeordnet und über den gesamten Entriegelungsvorgang nahezu gleichmäßig belastet werden.The transmission ratio is the ratio v K /ω R of the movement speed v K of the power transmission part to the angular speed ω R of the rotating part when the parts are in motion. With a smaller transmission ratio, the engine power is the same generates a greater force on the power transmission part. A greater force can thus advantageously act on the force transmission part during the course of the unlocking process, with the engine output remaining the same. The rotary motor can thus advantageously be of small design, arranged in a compact manner and loaded almost uniformly over the entire unlocking process.

Mit der vorbeschriebenen Anordnung wird der durch das Betätigungselement auf das Kraftübertragungsteil mittels Scherengetrieben übertragene Kraftverlauf nachempfunden. Bei Scherengetrieben verändert sich durch die Drehung der Scherenschenkel bei einer manuellen Betätigung des Betätigungselements ebenfalls die Übersetzung zwischen dem Betätigungselement und dem Kraftübertragungsteil im Verlauf des Entriegelungsvorgangs hin zu einer größeren Kraft auf das Kraftübertragungsteil.With the arrangement described above, the course of force transmitted by the actuating element to the force transmission part by means of scissor gears is simulated. In the case of scissor gears, the rotation of the scissor arm during manual actuation of the actuating element also changes the translation between the actuating element and the force transmission part in the course of the unlocking process towards a greater force on the force transmission part.

Die Pleuelstange kann antriebsseitig an einem Rad, insbesondere einem Zahnrad, in einem Koppelpunkt beabstandet von dem drehbar gelagerten Mittelpunkt des Rades angelagert sein, wobei sich der Mittelpunkt des Rads in der Nähe und besonders bevorzugt auf der Bewegungsachse des Kraftübertragungsteils befinden kann. An dem Kraftübertragungsteil greift dabei das Pleuel in einem Angriffspunkt an, der besonders bevorzugt auf dessen Bewegungsachse liegt. In einer Ausgangsstellung des Antriebs kann dann das Rad in einer Stellung stehen, bei der der Koppelpunkt maximal von der Bewegungsachse des Kraftübertragungsteils beabstandet ist. Der Winkel zwischen Pleuelstange und Bewegungsrichtung des Kraftübertragungsteils ist dann maximal, so dass der Kraftanteil, den die Pleuelstange in Bewegungsrichtung des Kraftübertragungsteils überträgt, minimal ist. Wird das Rad beim Entriegeln mittels des Rotationsmotors gedreht, so verändert sich der Abstand des Koppelpunkts zu einem Angriffspunkt der Pleuelstange an dem Kraftübertragungsteil beim Verstellen des Kraftübertragungsteils mittels des Antriebs quer zur Längsrichtung der Entriegelungsvorrichtung, so dass sich die auf das Kraftübertragungsteil übertragene Kraft über den Verstellweg des Rotationselements verändert. Insbesondere vergrößert sich diese Kraft, denn der Kraftanteil in Bewegungsrichtung des Kraftübertragungsteils wird mit kleiner werdendem Winkel größer.On the drive side, the connecting rod can be attached to a wheel, in particular a gear wheel, at a coupling point spaced from the rotatably mounted center point of the wheel, with the center point of the wheel being able to be located near and particularly preferably on the movement axis of the power transmission part. The connecting rod acts on the force-transmitting part at a point which is particularly preferably on its axis of movement. In an initial position of the drive, the wheel can then be in a position in which the coupling point is at a maximum distance from the movement axis of the force transmission part. The angle between the connecting rod and the direction of movement of the force transmission part is then at a maximum, so that the proportion of force which the connecting rod transmits in the direction of movement of the force transmission part is minimal. If the wheel is turned by means of the rotary motor when unlocking, the distance between the coupling point and a point of application of the connecting rod on the force transmission part changes when the force transmission part is adjusted by means of the drive transversely to the longitudinal direction of the unlocking device, so that the force transmitted to the force transmission part changes over the adjustment path of the rotation element changed. In particular, this force increases because the proportion of force in the direction of movement of the force transmission part increases as the angle decreases.

Der Antrieb kann an einem Gehäuse der Entriegelungsvorrichtung befestigt sein, er kann aber auch an dem Kraftübertragungsteil befestigt sein. In erstem Fall kann die Pleuelstange an dem Kraftübertragungsteil angreifen, etwa an einem an diesem angeformten Stift, um diese zu verstellen, während der Antrieb sich gegen das Gehäuse abstützt. In zweitem Fall kann die Pleuelstange an dem Gehäuse oder einem damit verbundenen Teil angreifen, etwa an einen an dem Gehäuse angeformten Stift, und der Antrieb wird mit dem Kraftübertragungsteil zusammen verstellt.The drive can be attached to a housing of the unlocking device, but it can also be attached to the power transmission part. In the first case, the connecting rod can act on the power transmission part, for example on a pin formed on this, in order to adjust it while the drive is supported against the housing. In the second case, the connecting rod can act on the housing or on a part connected thereto, for example on a pin formed on the housing, and the drive is adjusted together with the power transmission part.

In jedem Falle ist es vorteilhaft, wenn der Antrieb nicht das Kraftübertragungsteil blockieren kann, wenn die Entriegelungsvorrichtung manuell über das Betätigungselement bedient werden soll. Zu diesem Zweck sollte ein entsprechender Freilauf zwischen Rotationsmotor und Kraftübertragungsteil vorgesehen sein. Grundsätzlich kann ein solcher Freilauf an jeder Stelle des Antriebsgetriebes zwischen Rotationsmotor und Kraftübertragungsteil vorgesehen sein. Es wird bei einer Pleuelstange, die an einem Stift angreift, bevorzugt, dass zwischen diesen Teilen der Freilauf vorgesehen ist und sich Pleuelstange und Stift frei gegeneinander bewegen können. Dafür kann etwa die Pleuelstange eine Ausnehmung, insbesondere ein Langloch, aufweisen, in der sich der Stift bewegen kann, ohne eine Kraft auf die Pleuelstange auszuüben, bzw. ohne die Pleuelstange so zu bewegen, dass sie gegen einen Widerstand des Antriebsgetriebes und des Rotationsmotors Arbeit verrichten muss. Vorteilhaft muss ein Benutzer so nur die zum Entriegeln der Tür notwendige Kraft auf das Betätigungselement aufbringen. In die andere Richtung, in der die Pleuelstange bei Betätigung des Antriebs auf das Kraftübertragungsteil wirkt, muss dabei eine Kopplung bestehen.In any case, it is advantageous if the drive cannot block the force transmission part when the unlocking device is to be operated manually via the actuating element. For this purpose, a corresponding freewheel should be provided between the rotary motor and the power transmission part. In principle, such a freewheel can be provided at any point in the drive gear between the rotary motor and the power transmission part. In the case of a connecting rod which acts on a pin, it is preferable for the freewheel to be provided between these parts and for the connecting rod and pin to be able to move freely in relation to one another. For this purpose, the connecting rod can have a recess, in particular a slot, in which the pin can move without exerting a force on the connecting rod or without moving the connecting rod in such a way that it works against a resistance of the drive gear and the rotary motor must perform. Advantageously, a user only has to apply the force required to unlock the door to the actuating element. In the other direction, in which the connecting rod acts on the force transmission part when the drive is actuated, there must be a coupling.

In einer Ausführungsform weist das Antriebsgetriebe mehrere Rotationselemente auf. So kann das Antriebsgetriebe insbesondere ein Zahnradgetriebe sein. Vorteilhaft kann so eine besonders günstige Übersetzung eingestellt werden, so dass der Rotationsmotor möglichst klein ausgelegt werden kann. Der Rotationsmotor sowie das Antriebsgetriebe lassen sich dann auf einem kleinen Bauraum unterbringen und sehr kompakt gestalten. Als Rotationselemente sind neben Zahnrädern auch Wellen, Hebel, Spindeln oder Schnecken mit Schneckenrädern möglich.In one embodiment, the drive gear has a plurality of rotating elements. In particular, the drive mechanism can be a gear mechanism. A particularly favorable translation can advantageously be set in this way, so that the rotary motor can be designed as small as possible. The rotary motor and the drive gear can then be accommodated in a small space and made very compact. In addition to gear wheels, shafts, levers, spindles or worms with worm gears are also possible as rotating elements.

In einer Ausführungsform weist das Antriebsgetriebe mehrere verschiedene Rotationselemente auf, etwa eine Motorwelle und mindestens ein Zahnrad, dass von der Motorwelle angetrieben wird. Die Auswahl der Rotationselemente und der genauen Bauweise des Getriebes hängt dabei maßgeblich von der benötigten Kraft an dem Kraftübertragungsteil sowie von der Geometrie der Entriegelungsvorrichtung ab und kann für verschiedene Entriegelungsvorrichtungen entsprechend angepasst werden.In one embodiment, the drive gear has a plurality of different rotating elements, such as a motor shaft and at least one gear wheel that is driven by the motor shaft. The selection of the rotating elements and the precise design of the gear mechanism depends largely on the force required on the force transmission part and on the geometry of the unlocking device and can be adjusted accordingly for different unlocking devices.

Als Rotationsmotor kommt insbesondere ein Elektromotor in Betracht, da dieser sich sehr klein ausführen lässt.An electric motor is particularly suitable as the rotary motor, since it can be made very small.

In einer besonders bevorzugten Ausführungsform ist an dem Kraftübertragungsteil neben dem Antrieb auch eine Sperrvorrichtung angeordnet, die auf das Kraftübertragungsteil wirken kann. So lassen sich mehrere Funktionen in einer Entriegelungsvorrichtung kombinieren. Etwa kann die Tür gegen unberechtigte Benutzung durch die Sperrvorrichtung gesperrt werden, während durch den Antrieb die Tür automatisch entriegelt werden kann, etwa um einen Zutritt von der Außenseite kurzzeitig zu gewähren. Eine solche Entriegelungsvorrichtung kann dann an einer Tür eingesetzt werden, die im Alltag versperrt sein muss, von innen entfluchtbar sein muss und von außen nicht über ein Betätigungselement bedienbar ist, jedoch im Rahmen eines Zugangssystems entriegelbar für das Öffnen von außen sein muss. Vorteilhaft müssen dann an der Tür neben der Entriegelungsvorrichtung keine weiteren Funktionsbauteile angeordnet und/oder eingebaut werden.In a particularly preferred embodiment, a blocking device, which can act on the force transmission part, is also arranged on the force transmission part in addition to the drive. In this way, several functions can be combined in one unlocking device. For example, the door can be locked against unauthorized use by the locking device, while the door can be unlocked automatically by the drive, for example to allow access from the outside for a short time. Such an unlocking device can then be used on a door that must be locked in everyday life, must be able to be escaped from the inside and cannot be operated from the outside via an actuating element, but must be able to be unlocked for opening from the outside as part of an access system. Advantageously, no further functional components then have to be arranged and/or installed on the door in addition to the unlocking device.

Figur 1 zeigt eine Entriegelungsvorrichtung 1 mit einem Gehäuse 2 und einem Betätigungselement 3 in Form einer Druckstange. Weiterhin weist die Entriegelungsvorrichtung 1 Endkappen 4 mit jeweils einem feststehenden, an dem Gehäuse 2 angeformten unteren Teil 4a und einem mit dem Betätigungselement 3 gemeinsam beweglichen oberen Teil 4b. Das Betätigungselement und die oberen Teile 4b der Endkappen 4 können zur Entriegelung einer nicht dargestellten Tür in das Gehäuse 2 eingedrückt werden. figure 1 shows an unlocking device 1 with a housing 2 and an actuating element 3 in the form of a push rod. Furthermore, the unlocking device 1 has end caps 4, each with a stationary lower part 4a formed on the housing 2 and an upper part 4b which can be moved together with the actuating element 3. The actuating element and the upper parts 4b of the end caps 4 can be pushed into the housing 2 to unlock a door (not shown).

Aus der in Figur 2 dargestellten Detailansicht ist zu erkennen, dass im Inneren der Entriegelungsvorrichtung 1 ein Getriebe 5 angeordnet ist, mittels dem die Bewegung eines nicht dargestellte Betätigungselements 3 beim Eindrücken in das Gehäuse 2 auf ein Kraftübertragungsteil 6 übertragen wird, welches sich in Längsrichtung LR der Entriegelungsvorrichtung 1 bewegen kann und dabei mittelbar oder unmittelbar auf ein Schloss, etwa auf eine Schlossnuss, zum Entriegeln des Schlosses wirkt. Weiterhin koppelt das Kraftübertragungsteil 6 auch das dargestellte Getriebe 5 mit einem weiteren, nicht dargestellten gleichartigen Getriebe 5 auf der nicht in Figur 2 dargestellten Seite der Entriegelungsvorrichtung 1, welches ebenfalls das Betätigungselement 3 trägt und mit dem Kraftübertragungsteils 6 verbindet.from the inside figure 2 The detailed view shown in the detailed view shows that a gear 5 is arranged inside the unlocking device 1, by means of which the movement of an actuating element 3 (not shown) when pressed into the housing 2 is transmitted to a force transmission part 6, which can move in the longitudinal direction LR of the unlocking device 1 and acts directly or indirectly on a lock, such as a lock follower, to unlock the lock. Furthermore, the power transmission part 6 also couples the gear 5 shown to another, not shown, similar gear 5 on the not shown in figure 2 shown side of the unlocking device 1, which also carries the actuating element 3 and connects it to the power transmission part 6.

An dem Kraftübertragungsteil 6 greift ein Antrieb 7 an, der eine Pleuelstange 8 aufweist, die an einem Stift 9 angreift, der an dem Kraftübertragungsteil 6 befestigt ist, etwa mittels Schrauben 10. Die Pleuelstange 8 weist zudem ein Langloch 11 auf, mittels dem der Antrieb 7 und das Kraftübertragungsteil 6 voneinander entkoppelt sind. Mittels des Antriebs 7 kann das Kraftübertragungsteil 6 in Längsrichtung LR verstellt werden, wobei die Getriebe 5 ebenfalls betätigt werden, falls diese fest mit dem Kraftübertragungsteil 6 verbundenen sind, so dass das Betätigungselement 3 in das Gehäuse 2 hineingezogen wird. Es ist jedoch auch möglich, eine Entkopplung zwischen dem Kraftübertragungsteil 6 und den Getrieben 5 vorzusehen, so dass das Betätigungselement 3 nicht mit eingezogen wird, wenn der Antrieb 7 das Kraftübertragungsteil 6 verstellt. Wird das Betätigungselement 3 manuell in das Gehäuse 2 eingedrückt, ohne dass der Antrieb 7 betätigt wird, so kann sich das Kraftübertragungsteil 6 frei gegenüber dem Antrieb 7 in Längsrichtung LR bewegen. Der Stift 9 gleitet dann in dem Langloch 11 entlang, ohne die Pleuelstange 8 mit einer Zugkraft zu beaufschlagen. Die Pleuelstange 8 wird dabei lediglich verdreht.A drive 7 acts on the force transmission part 6 and has a connecting rod 8 which acts on a pin 9 which is fastened to the force transmission part 6 is, for example by means of screws 10. The connecting rod 8 also has a slot 11, by means of which the drive 7 and the force transmission part 6 are decoupled from one another. The power transmission part 6 can be adjusted in the longitudinal direction LR by means of the drive 7 , with the gears 5 also being actuated if they are firmly connected to the power transmission part 6 , so that the actuating element 3 is drawn into the housing 2 . However, it is also possible to provide a decoupling between the force transmission part 6 and the gears 5 so that the actuating element 3 is not drawn in when the drive 7 adjusts the force transmission part 6 . If the actuating element 3 is pressed manually into the housing 2 without the drive 7 being actuated, the force transmission part 6 can move freely in relation to the drive 7 in the longitudinal direction LR. The pin 9 then slides along in the slot 11 without subjecting the connecting rod 8 to a tensile force. The connecting rod 8 is only twisted.

Die Figuren 3, 4 und 5 zeigen Detailansichten des Antriebs 7 von innen. In Figur 3 ist dabei die Ausgangstellung dargestellt, die Antrieb 7 und Kraftübertragungsteil 6 einnehmen, wenn das Betätigungselement 3 nicht eingedrückt ist und der Antrieb 7 nicht betätigt wird. Figur 4 zeigt die Stellung, die Antrieb 7 und Kraftübertragungsteil 6 einnehmen, wenn das Kraftübertragungsteil 6 mittels des Antriebs 7 in Längsrichtung LR verstellt wurde, um das Schloss zu entriegeln. Figur 5 zeigt die Stellung, in der sich Antrieb 7 und Kraftübertragungsteil 6 befinden, wenn das Betätigungselement 3 manuell betätigt wird, der Antrieb 7 jedoch nicht betätigt wird.the Figures 3, 4 and 5 show detailed views of the drive 7 from the inside. FIG. 3 shows the starting position that drive 7 and force transmission part 6 assume when actuating element 3 is not pressed in and drive 7 is not actuated. figure 4 shows the position that the drive 7 and power transmission part 6 assume when the power transmission part 6 has been adjusted by means of the drive 7 in the longitudinal direction LR in order to unlock the lock. figure 5 shows the position in which the drive 7 and the power transmission part 6 are located when the operating element 3 is actuated manually, but the drive 7 is not actuated.

Der Antrieb 7 weist einen Rotationsmotor 12 sowie ein Antriebsgetriebe 13 auf, das die Motorwelle 13a sowie mehrere Zahnräder 13b, 13c, 13d und 13e umfasst. An dem Zahnrad 13e ist an einem Koppelpunkt KP, der von dem Mittelpunkt M des Zahnrads 13e beabstandet ist, die Pleuelstange 8 drehbar gelagert. Der Mittelpunkt M des Zahnrades 13e schneidet die Bewegungsachse BA des Kraftübertragungsteils 6. Die Pleuelstange 8 greift weiterhin an einem Angriffspunkt AP, der durch den Stift 9 gebildet ist, an dem Kraftübertragungsteil 6 an. Zum Entriegeln des Schlosses verdreht der Rotationsmotor 12 die Motorwelle 13a, wobei die Motorwelle 13a die Zahnräder 13b, 13c, 13d und 13e des Antriebsgetriebes 13 bewegt, woraufhin der Koppelpunkt KP der Pleuelstange 8 an dem Zahnrad 13e verdreht wird. Durch die Rotation des Zahnrades 13e verändert sich der Winkel α zwischen der Längsachse PA der Pleuelstange 8 und der Bewegungsachse BA des Kraftübertragungsteils 6. Durch die Verringerung des Winkels α bis hin zu einer 0°-Stellung in der komplett ausgefahrenen Stellung der Pleuelstange 8 gemäß Figur 4, steigt der Kraftanteil, der von der Pleuelstange 8 in Längsrichtung LR, die die Bewegungsrichtung des Kraftübertragungsteils 6 ist, von dem Antrieb 7 auf das Kraftübertragungsteil 6 aufgebracht werden kann. Im Verlaufe der Entriegelung sinkt daher das Übersetzungsverhältnis, wie es auch in Figur 6 in einem Diagramm dargestellt ist. Der in Figur 6 aufgetragen Drehwinkel ist dabei der Drehwinkel des Zahnrades 13e, wobei die Ausgangstellung gemäß Figur 3 0° entspricht und die Stellung gemäß Figur 4 90°. Weiterhin verringert sich während der Entriegelung der Abstand A zwischen dem Kopplungspunkt KP und dem Angriffspunkt AP. Der Kopplungspunkt KP bewegt sich in Querrichtung QR auf den Angriffspunkt AP zu, wobei die Pleuelstange 8 verdreht wird.The drive 7 has a rotary motor 12 and a drive gear 13, which includes the motor shaft 13a and a plurality of gears 13b, 13c, 13d and 13e. The connecting rod 8 is rotatably mounted on the gear 13e at a coupling point KP, which is spaced apart from the center point M of the gear 13e. The center point M of the gear wheel 13e intersects the movement axis BA of the power transmission part 6. The connecting rod 8 also acts on the power transmission part 6 at a point of application AP, which is formed by the pin 9. To unlock the lock, the rotary motor 12 turns the motor shaft 13a, the motor shaft 13a turning the gear wheels 13b, 13c, 13d and 13e of the drive gear 13 is moved, whereupon the coupling point KP of the connecting rod 8 on the gear wheel 13e is rotated. The rotation of the gear wheel 13e changes the angle α between the longitudinal axis PA of the connecting rod 8 and the movement axis BA of the power transmission part 6. By reducing the angle α down to a 0° position in the completely extended position of the connecting rod 8 according to figure 4 , the proportion of force that can be applied by the drive 7 to the force transmission part 6 by the connecting rod 8 in the longitudinal direction LR, which is the direction of movement of the force transmission part 6, increases. In the course of unlocking, the transmission ratio therefore decreases, as is also the case in figure 6 is shown in a diagram. the inside figure 6 plotted angle of rotation is the angle of rotation of the gear 13e, the starting position according to figure 3 corresponds to 0° and the position according to figure 4 90°. Furthermore, the distance A between the coupling point KP and the point of application AP decreases during unlocking. The coupling point KP moves in the transverse direction QR towards the point of application AP, with the connecting rod 8 being twisted.

Der Rotationsmotor 12 weist eine Anschlusseinheit 14 auf, an der Strom- und Signalleitungen angeschlossen werden können.The rotary motor 12 has a connection unit 14 to which power and signal lines can be connected.
