Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, an actuating lever chain and a drive for electrically opening the locking mechanism, wherein an additional drive is provided, which, if necessary, "locked” the actuating lever chain in its position in which the actuating lever chain is mechanically interrupted.
- a motor vehicle door lock of the structure described above is in the utility model DE 20 2010 013 611 U1 described.
- the overall aim here is to reduce the structural design with an identical range of functions, that is to say to realize an additional safety function through a coupling in the drive train between a so-called OBW drive (Open By Wire) and a pawl.
- OBW drive Open By Wire
- the procedure in the known motor vehicle door lock is that a switchable coupling between an actuating lever and a release lever of a lock mechanism is provided.
- the clutch can be "unlocked” into a first clutch state and brought into a second clutch state "locked”.
- the electrical opening of a locking mechanism with the aid of the electric drive is regularly accomplished so that an operator, for example, an outside door handle or a door inner handle acted upon. This regularly results in a switch operation, which is interpreted as an opening request. As a result, an opening signal is generated which causes the electric drive to be energized to electrically open the locking mechanism.
- blocking elements are used in practice, for example. The blocking element in question ensures a mechanical securing of the electric drive.
- the electric drive can electrically open the locking mechanism.
- the release of the blocking element is regularly coupled to a mechanical loading by means of the outside door handle or the inside door handle. That is, the outside door handle or the inside door handle is mechanically connected to the blocking element and ensures that the blocking element releases the electric drive, so that it can work in the opening sense on the locking mechanism. This has proven itself in principle.
- the invention is based on the technical problem of further developing such a motor vehicle door lock so that a solution is made available which, in principle, also enables a remote control, wherein in addition, a mechanical opening of the locking mechanism should succeed in emergency opening operation.
- a generic motor vehicle door lock in the invention is characterized in that the operating lever chain consistently "locked” maintains its position and only when the position "locked” the operating lever chain is reached, generates an opening signal for the drive to electrically open the locking mechanism is, with only in the event of an emergency opening or in the event of a crash the operating lever chain is effective and previously "unlocked” transferred to their position in which the locking mechanism can be opened mechanically via the operating lever chain so that, for example, rescue personnel can open an associated vehicle door.
- the motor vehicle door lock according to the invention has the previously described "temporary crash redundancy” (TCR).
- TCR temporary crash redundancy
- the electrical opening of the locking mechanism with the aid of the drive can always and only then take place when a corresponding opening signal is generated. That is, the locking and the electrical opening are linked together in such a way that no mechanical locking is possible without opening.
- the opening signal is coupled to that before the operating lever chain assumes its position "locked” or is transferred to this position.
- the additional drive does not mechanically act on the operating lever chain, if this has already taken their position "locked”. That is, the additional drive transfers the actuating lever chain "locked” into its position as needed.
- the operating lever chain consistently maintains its "locked” position. In this way, an unlocking is realized, which ensures that the operating lever chain is kept in the "locked” position.
- any mechanical loading of the actuating lever chain can not be implemented in an opening of the locking mechanism.
- the electric drive for electrically opening the Gesperres not ensure this, because the opening signal is missing. So there is maximum security.
- the invention opens up the possibility of fernzubedienen the drive for electrically opening the Gesperres. Because this is ultimately applied to the additional drive, which, if necessary, "transferred” locked the actuating lever chain in its position. At the same time, the admission of the additional drive ensures that the necessary opening signal is generated, so that the drive for electrically opening the locking mechanism can even run. The opening signal is of course only generated when the operating lever chain has reached its "locked” position.
- the additional drive is designed so that its application in the direction "locked” the actuating lever chain at the end of the travel also generates the respective opening signal.
- a motor vehicle door lock is shown, which is equipped with a not explicitly shown ratchet of substantially rotary latch and pawl.
- the motor vehicle door lock has a release lever 1.
- the release lever 1 is rotatably mounted together with a blocking element or blocking lever 2 about a common axis 3 in a lock housing 4.
- a drive 4, 5 is provided, which serves for the electrical opening of the locking mechanism.
- the drive 4, 5 is composed of an electric motor 4 and a driven pulley 5, which can perform rotary movements initiated by the electric motor 4 in the clockwise direction and in the counterclockwise direction about its axis 6.
- a movement of the driven pulley 5 in the counterclockwise direction about its axis 6 ensures that a provided in plan view of the back contour with the release lever 1 interacts such that the release lever 1 is pivoted about its axis 3 in a clockwise direction (see. Fig. 1 ).
- the locking mechanism is opened, in which the release lever 1, the pawl of the locking mechanism pivots away from the associated rotary latch and opens the rotary latch spring-assisted.
- a lock pin previously caught by the catch comes free.
- the clockwise movement of the driven pulley 5, however, corresponds to the emergency opening and at the same time that the locking mechanism can be opened mechanically.
- an additional drive 7, 8 used according to the invention which is comparable to the drive 4, 5 is constructed.
- the additional drive 7, 8 is also composed of an electric motor 7 and a driven pulley 8.
- the electric motor 7 is equipped on its output shaft with a worm which meshes with an outer peripheral toothing of the driven pulley 8 to pivot the driven pulley 8 about its axis in a clockwise or counterclockwise direction.
- the additional drive 7, 8 in the exemplary embodiment is a safety drive.
- the backup drive may act as a child safety drive and / or anti-theft drive.
- the additional drive 7, 8 or backup drive is a child safety drive.
- the locking lever 10 is consistently “locked” in its position, because insofar an unlocking lock is realized, as will be explained in more detail below. Only when the so-called emergency opening operation is carried out, the locking lever 10 is typically transferred to its "unlocked” position, so that in this (rare) case, an actuating lever or operating lever chain 12 is effective and can mechanically open the locking mechanism. As already explained above, the emergency opening corresponds to a clockwise movement of the driven pulley 5.
- the operating lever mechanism 12 has in addition to a lever 12 in addition to a clutch lever, which interacts depending on its position with the release lever 1 or not for further basic structure.
- the actuating lever or connecting lever 12 and the clutch lever are then mechanically connected via an intermediate lever with the release lever 1, depending on the position of the clutch lever.
- the operating lever chain 12 is “locked” in its position, the operating lever chain 12 is mechanically interrupted and is not lying continuous mechanical connection, for example, from an outside door handle or inside door handle up to the release lever 1 before.
- the position "unlocked” the actuating lever chain 12 corresponds to the fact that the release lever 1 can be acted upon by the actuating lever chain 12 mechanically to open the locking mechanism. This is only the case in the embodiment and only possible if a so-called emergency opening is to take place or should take place.
- the additional drive 7, 8 or child safety drive is mechanically connected to the adjusting lever 12.
- the adjusting lever 12 is pivotally connected to the driven pulley 8 of the additional drive 7, 8.
- the relevant additional drive 7, 8 operates on the coupling lever of the actuating lever mechanism 12.
- the adjusting lever 12 has in detail a locking pin 11 which engages in an associated recess on the locking lever 10. In this way, the adjusting lever 12 can pivot the locking lever 10, for example, in the positions "locked” or “unlocked” convict and thereby implement the parental control function.
- the additional drive 7, 8 acts on a sensor when the actuating lever mechanism 12 is in the "locked" position.
- This sensor may be a child safety sensor or child safety switch. Only when the sensor in question is acted upon, the initially mentioned opening signal is generated, which causes the drive 4, 5 is energized to electrically open the locking mechanism. That is, the electric opening operation of the locking requires that a signal from the sensor from a not registered control unit is registered, to which the sensor is connected.
- the application of the sensor presupposes that the additional drive 7, 8 from its position “off or child safety off” as shown in the Fig. 1 at the transition to Fig. 2 finally the position after the Fig. 3 reached, which corresponds to the position "on or parental lock on”. Only when the additional drive 7, 8 this position after Fig. 3 has reached, the sensor undergoes a corresponding action and the drive 4, 5 electrically open the locking mechanism.
- the invention ensures that, on the one hand, the locking lever 10 definitively assumes or retains its "locked” position because the counterclockwise movement of the driven pulley 8 of the additional drive 7 connected to the transition from the "off" position to the “on” position, 8 corresponds to the fact that the locking lever 10 is pivoted about its axis, if necessary, in a clockwise direction, as in the transition from the Fig. 1 to Fig. 2 becomes clear.
- the additional drive 7, 8 the operating lever chain 12 is transferred to its "locked” position, in which there is no continuous mechanical connection to the triggering lever 1. Any mechanical loading of the actuating lever chain 12 can therefore not lead to an unwanted opening of the locking mechanism.
- the signal generated by the sensor in this way is now interpreted as an opening signal and ensures that the drive 4, 5 electrically opens the locking mechanism.

Description
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit einem Gesperre, einer Betätigungshebelkette und einem Antrieb zum elektrischen Öffnen des Gesperres, wobei ein zusätzlicher Antrieb vorgesehen ist, welcher die Betätigungshebelkette bedarfsweise in ihre Stellung "verriegelt" überführt, in der die Betätigungshebelkette mechanisch unterbrochen ist.The invention relates to a motor vehicle door lock, with a locking mechanism, an actuating lever chain and a drive for electrically opening the locking mechanism, wherein an additional drive is provided, which, if necessary, "locked" the actuating lever chain in its position in which the actuating lever chain is mechanically interrupted.
Ein Kraftfahrzeugtürverschluss des eingangs beschriebenen Aufbaus wird in dem Gebrauchsmuster
Eine manuelle Betätigung des Betätigungshebels in der Stellung "entriegelt" der Kupplung sorgt über den Auslösehebel für ein manuelles Ausheben der Sperrklinke. Die Kupplung lässt sich darüber hinaus in einen dritten Kupplungszustand "OBW" bringen. Ausschließlich in diesem Zustand wird der Auslösehebel durch den OBW-Antrieb motorisch betätigt.Manual operation of the operating lever in the "unlocked" position of the clutch provides over the release lever for manual release of the pawl. The clutch can also be brought into a third coupling state "OBW". Only in this condition is the release lever actuated by the OBW drive.
Bei einem Kraftfahrzeugtürverschluss entsprechend der
Das elektrische Öffnen eines Gesperres mit Hilfe des elektrischen Antriebes wird regelmäßig so bewerkstelligt, dass ein Bediener beispielsweise einen Türaußengriff oder auch einen Türinnengriff beaufschlagt. Daraus resultiert regelmäßig eine Schalterbetätigung, die als Öffnungswunsch interpretiert wird. Als Folge hiervon wird ein Öffnungssignal erzeugt, welches dazu führt, dass der elektrische Antrieb zum elektrischen Öffnen des Gesperres bestromt wird. Um an dieser Stelle Fehlbestromungen schon vom Ansatz her auszuschleißen, werden in der Praxis beispielsweise Blockierelemente eingesetzt. Das betreffende Blockierelement sorgt für eine mechanische Sicherung des elektrischen Antriebes.The electrical opening of a locking mechanism with the aid of the electric drive is regularly accomplished so that an operator, for example, an outside door handle or a door inner handle acted upon. This regularly results in a switch operation, which is interpreted as an opening request. As a result, an opening signal is generated which causes the electric drive to be energized to electrically open the locking mechanism. In order to compensate for erroneous currents at the point of view, blocking elements are used in practice, for example. The blocking element in question ensures a mechanical securing of the electric drive.
Erst wenn das Blockierelement den elektrischen Antrieb freigibt, kann der elektrische Antrieb das Gesperre elektrisch öffnen. Die Freigabe des Blockierelementes ist regelmäßig an eine mechanische Beaufschlagung mit Hilfe des Türaußengriffes oder des Türinnengriffes gekoppelt. Das heißt, der Türaußengriff oder auch der Türinnengriff ist mechanisch mit dem Blockierelement verbunden und sorgt dafür, dass das Blockierelement den elektrischen Antrieb freigibt, damit dieser in öffnendem Sinne auf das Gesperre arbeiten kann. Das hat sich grundsätzlich bewährt.Only when the blocking element releases the electric drive, the electric drive can electrically open the locking mechanism. The release of the blocking element is regularly coupled to a mechanical loading by means of the outside door handle or the inside door handle. That is, the outside door handle or the inside door handle is mechanically connected to the blocking element and ensures that the blocking element releases the electric drive, so that it can work in the opening sense on the locking mechanism. This has proven itself in principle.
In der Praxis ergeben sich allerdings zunehmend Anforderungen dahingehend, den Antrieb zum elektrischen Öffnen des Gesperres fernzubedienen. In diesem Fall fällt eine mechanische Beaufschlagung weg, weil letztendlich die zugehörige Kraftfahrzeugtür elektrisch und fernbedienbar geöffnet werden soll, und zwar ohne das zusätzlich beispielsweise ein Außentürgriff eine Betätigung erfährt. Hierfür existieren bisher keine überzeugenden Lösungen.In practice, however, increasingly arise requirements to remotely control the drive for electrically opening the locking mechanism. In this case, falls away a mechanical loading, because ultimately the associated motor vehicle door is to be opened electrically and remote-controlled, and Although without the addition, for example, an outside door handle undergoes an operation. There are no convincing solutions for this.
Der Erfindung liegt das technische Problem zugrunde, einen derartigen Kraftfahrzeugtürverschluss so weiterzuentwickeln, dass eine Lösung zur Verfügung gestellt wird, die grundsätzlich auch eine Fernbedienung ermöglicht, wobei zusätzlich im Notöffnungsbetrieb ein mechanisches Öffnen des Gesperres gelingen soll.The invention is based on the technical problem of further developing such a motor vehicle door lock so that a solution is made available which, in principle, also enables a remote control, wherein in addition, a mechanical opening of the locking mechanism should succeed in emergency opening operation.
Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Kraftfahrzeugtürverschluss im Rahmen der Erfindung dadurch gekennzeichnet, dass die Betätigungshebelkette durchweg ihre Position "verriegelt" beibehält und erst wenn die Position "verriegelt" der Betätigungshebelkette erreicht ist, ein Öffnungssignal für den Antrieb zum elektrischen Öffnen des Gesperres erzeugt wird, wobei nur im Falle einer Notöffnung bzw. im Crashfall die Betätigungshebelkette wirksam ist und zuvor in ihre Stellung "entriegelt" überführt wird, in der das Gesperre mechanisch über die Betätigungshebelkette geöffnet werden kann, damit beispielsweise Rettungspersonal eine zugehörige Kraftfahrzeugtür öffnen kann.To solve this technical problem, a generic motor vehicle door lock in the invention is characterized in that the operating lever chain consistently "locked" maintains its position and only when the position "locked" the operating lever chain is reached, generates an opening signal for the drive to electrically open the locking mechanism is, with only in the event of an emergency opening or in the event of a crash the operating lever chain is effective and previously "unlocked" transferred to their position in which the locking mechanism can be opened mechanically via the operating lever chain so that, for example, rescue personnel can open an associated vehicle door.
Im Rahmen der Erfindung ist folglich sichergestellt, dass sich die Betätigungshebelkette durchweg in ihrer Stellung "verriegelt" befindet, und zwar auch dann, wenn der elektrische Antrieb zum elektrischen Öffnen des Gesperres bestromt wird. Nur im Falle einer Notöffnung bzw. im Crashfall wird so vorgegangen, dass die Betätigungshebelkette zuvor in ihre Stellung "entriegelt" überführt wird, damit beispielsweise Rettungspersonal eine zugehörige Kraftfahrzeugtür öffnen kann. Dazu muss lediglich ein Türgriff mechanisch beaufschlagt werden.In the context of the invention, it is thus ensured that the actuating lever chain is consistently "locked" in its position, even if the electric drive is energized to electrically open the locking mechanism. Only in the case of an emergency opening or in the event of a crash, the procedure is such that the operating lever chain is previously transferred to its "unlocked" position so that, for example, rescue personnel can open an associated motor vehicle door. For this purpose, only a door handle must be applied mechanically.
Das heißt, der erfindungsgemäße Kraftfahrzeugtürverschluss verfügt über die zuvor bereits beschriebene "temporäre Crash-Redundanz" (TCR). Bei einem Unfall stellt hierzu der elektrische Antrieb zum elektrischen Öffnen des Gesperres im dann ablaufenden Notbetrieb sicher, dass das Gesperre mechanisch redundant geöffnet werden kann. Das geschieht unabhängig von dem elektrischen Antrieb.That is, the motor vehicle door lock according to the invention has the previously described "temporary crash redundancy" (TCR). In an accident, this is the electric drive for electrically opening the Locking in then running emergency operation sure that the locking mechanism can be opened mechanically redundant. This happens independently of the electric drive.
Im Rahmen der Erfindung wird nun sichergestellt, dass das elektrische Öffnen des Gesperres mit Hilfe des Antriebes immer und erst dann erfolgen kann, wenn ein entsprechendes Öffnungssignal erzeugt wird. D. h., das Verriegeln und das elektrische Öffnen sind derart miteinander verknüpft, dass kein mechanisches Verriegeln möglich ist ohne zu öffnen. Das Öffnungssignal ist daran gekoppelt, dass zuvor die Betätigungshebelkette ihre Stellung "verriegelt" einnimmt bzw. in diese Stellung überführt wird. Selbstverständlich braucht in diesem Kontext der zusätzliche Antrieb nicht auf die Betätigungshebelkette mechanisch einwirken, sofern diese bereits ihre Stellung "verriegelt" eingenommen hat. Das heißt, der zusätzliche Antrieb überführt die Betätigungshebelkette bedarfsweise in ihre Stellung "verriegelt".In the context of the invention it is now ensured that the electrical opening of the locking mechanism with the aid of the drive can always and only then take place when a corresponding opening signal is generated. That is, the locking and the electrical opening are linked together in such a way that no mechanical locking is possible without opening. The opening signal is coupled to that before the operating lever chain assumes its position "locked" or is transferred to this position. Of course, in this context, the additional drive does not mechanically act on the operating lever chain, if this has already taken their position "locked". That is, the additional drive transfers the actuating lever chain "locked" into its position as needed.
Erst wenn die Position "verriegelt" der Betätigungshebelkette erreicht ist, wird das bereits angesprochene Öffnungssignal erzeugt, welches letztlich dazu führt, dass der elektrische Antrieb zum elektrischen Öffnen des Gesperres bestromt wird.Only when the position "locked" the operating lever chain is reached, the already mentioned opening signal is generated, which ultimately leads to the electric drive is energized to electrically open the locking mechanism.
Das heißt, die Betätigungshebelkette behält durchweg ihre Position "verriegelt" bei. Auf diese Weise wird eine Entriegelungssperre realisiert, welche dafür sorgt, dass die Betätigungshebelkette in der Stellung "verriegelt" gehalten wird. Dadurch können etwaige mechanische Beaufschlagungen der Betätigungshebelkette nicht in eine Öffnung des Gesperres umgesetzt werden. Außerdem kann auch der elektrische Antrieb zum elektrischen Öffnen des Gesperres hierfür nicht sorgen, weil das Öffnungssignal fehlt. Es ist also eine maximale Sicherheit gegeben.That is, the operating lever chain consistently maintains its "locked" position. In this way, an unlocking is realized, which ensures that the operating lever chain is kept in the "locked" position. As a result, any mechanical loading of the actuating lever chain can not be implemented in an opening of the locking mechanism. In addition, the electric drive for electrically opening the Gesperres not ensure this, because the opening signal is missing. So there is maximum security.
Zugleich eröffnet die Erfindung die Möglichkeit, den Antrieb zum elektrischen Öffnen des Gesperres fernzubedienen. Denn dazu wird letztendlich der zusätzliche Antrieb beaufschlagt, welcher die Betätigungshebelkette bedarfsweise in ihre Stellung "verriegelt" überführt. Zugleich sorgt die Beaufschlagung des zusätzlichen Antriebes dafür, dass das notwendige Öffnungssignal erzeugt wird, damit der Antrieb zum elektrischen Öffnen des Gesperres überhaupt loslaufen kann. Das Öffnungssignal wird selbstverständlich erst dann erzeugt, wenn die Betätigungshebelkette ihre Stellung "verriegelt" erreicht hat. Zu diesem Zweck ist der zusätzliche Antrieb so ausgelegt, dass seine Beaufschlagung in Richtung "verriegelt" der Betätigungshebelkette am Ende des Stellweges zugleich das betreffende Öffnungssignal erzeugt.At the same time, the invention opens up the possibility of fernzubedienen the drive for electrically opening the Gesperres. Because this is ultimately applied to the additional drive, which, if necessary, "transferred" locked the actuating lever chain in its position. At the same time, the admission of the additional drive ensures that the necessary opening signal is generated, so that the drive for electrically opening the locking mechanism can even run. The opening signal is of course only generated when the operating lever chain has reached its "locked" position. For this purpose, the additional drive is designed so that its application in the direction "locked" the actuating lever chain at the end of the travel also generates the respective opening signal.
Weitere Einzelheiten und vorteilhafte Ausgestaltungen werden in den Unteransprüchen beschrieben. Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

- the motor vehicle door lock according to the invention in different functional positions.
In den Figuren ist ein Kraftfahrzeugtürverschluss dargestellt, welcher mit einem nicht explizit gezeigten Gesperre aus im Wesentlichen Drehfalle und Sperrklinke ausgerüstet ist. Zur Beaufschlagung des Gesperres verfügt der Kraftfahrzeugtürverschluss über einen Auslösehebel 1. Der Auslösehebel 1 ist zusammen mit einem Blockierelement bzw. Blockierhebel 2 um eine gemeinsame Achse 3 drehbar in einem Schlossgehäuse 4 gelagert.In the figures, a motor vehicle door lock is shown, which is equipped with a not explicitly shown ratchet of substantially rotary latch and pawl. To actuate the locking mechanism, the motor vehicle door lock has a
Zum Öffnen des Gesperres ist es erforderlich, den Auslösehebel 1 um seine Achse 3 im Uhrzeigersinn zu verschwenken, wie ein zugehöriger Pfeil in der
Eine Bewegung der Abtriebsscheibe 5 im Gegenuhrzeigersinn um ihre Achse 6 sorgt dafür, dass eine in Aufsicht an der Rückseite vorgesehene Kontur mit dem Auslösehebel 1 derart wechselwirkt, dass der Auslösehebel 1 um seine Achse 3 im Uhrzeigersinn verschwenkt wird (vgl.
Ergänzend zu dem bereits angesprochenen Antrieb 4, 5 zum elektrischen Öffnen des Gesperres erkennt man einen erfindungsgemäß eingesetzten zusätzlichen Antrieb 7, 8, welcher vergleichbar wie der Antrieb 4, 5 aufgebaut ist. Tatsächlich setzt sich der zusätzliche Antrieb 7, 8 ebenfalls aus einem Elektromotor 7 und einer Abtriebsscheibe 8 zusammen. Wie im Falle des Antriebes 4, 5 ist der Elektromotor 7 an seiner Abtriebswelle mit einer Schnecke ausgerüstet, die mit einer außenumfangseitigen Verzahnung der Abtriebsscheibe 8 kämmt, um die Abtriebsscheibe 8 um ihre Achse im Uhrzeigersinn oder im Gegenuhrzeigersinn zu verschwenken.In addition to the previously mentioned
Bei dem zusätzlichen Antrieb 7, 8 handelt es sich im Ausführungsbeispiel um einen Sicherungsantrieb. Der Sicherungsantrieb kann als Kindersicherungsantrieb und/oder Diebstahlsicherungsantrieb fungieren. Im Ausführungsbeispiel handelt es sich bei dem zusätzlichen Antrieb 7, 8 bzw. Sicherungsantrieb um einen Kindersicherungsantrieb. Dieser arbeitet auf einen Verriegelungshebel 10, welcher um seine Achse verschwenkbar im Schlossgehäuse gelagert ist. Der Verriegelungshebel 10 kann im Wesentlichen in eine Stellung "entriegelt" oder in die Position "verriegelt" entsprechend den
Tatsächlich befindet sich der Verriegelungshebel 10 durchweg in seiner Stellung "verriegelt", weil insofern eine Entriegelungssperre realisiert ist, wie nachfolgend noch näher erläutert wird. Nur dann, wenn der sogenannte Notöffnungsbetrieb erfolgt, wird typischerweise der Verriegelungshebel 10 in seine Stellung "entriegelt" überführt, so dass in diesem (seltenen) Fall ein Betätigungshebelwerk bzw. eine Betätigungshebelkette 12 wirksam ist und das Gesperre mechanisch öffnen kann. Wie zuvor bereits erläutert, korrespondiert die Notöffnung zu einer Uhrzeigersinnbewegung der Abtriebsscheibe 5.In fact, the locking
Zum weiteren grundsätzlichen Aufbau gehört noch das bereits angesprochene Betätigungshebelwerk bzw. die Betätigungshebelkette 12. Das Betätigungshebelwerk 12 weist neben einem Stellhebel 12 zusätzlich noch einen Kupplungshebel auf, welcher je nach seiner Position mit dem Auslösehebel 1 wechselwirkt oder nicht. Der Stellhebel bzw. Verbindungshebel 12 und der Kupplungshebel sind dann noch über einen Zwischenhebel mechanisch mit dem Auslösehebel 1 verbindbar, und zwar je nach Stellung des Kupplungshebels.The operating
Befindet sich die Betätigungshebelkette 12 in ihrer Stellung "verriegelt", so ist die Betätigungshebelkette 12 mechanisch unterbrochen und liegt keine durchgängige mechanische Verbindung beispielsweise von einem Türaußengriff oder Türinnengriff bis hin zum Auslösehebel 1 vor. Dagegen korrespondiert die Position "entriegelt" der Betätigungshebelkette 12 dazu, dass der Auslösehebel 1 über die Betätigungshebelkette 12 mechanisch zum Öffnen des Gesperres beaufschlagt werden kann. Das ist im Ausführungsbeispiel nur dann der Fall und nur dann möglich, wenn eine sogenannte Notöffnung erfolgt oder erfolgen soll.If the operating
Der zusätzliche Antrieb 7, 8 bzw. Kindersicherungsantrieb ist mechanisch mit dem Stellhebel 12 verbunden. Tatsächlich ist der Stellhebel 12 gelenkig an die Abtriebsscheibe 8 des zusätzlichen Antriebes 7, 8 angeschlossen. Über den an den zusätzlichen Antrieb 7, 8 angeschlossenen Stellhebel 12 arbeitet der betreffende zusätzliche Antrieb 7, 8 auf den Kupplungshebel des Betätigungshebelwerkes 12.The
Dazu verfügt der Stellhebel 12 im Detail über einen Verriegelungszapfen 11, der in eine zugehörige Ausnehmung am Verriegelungshebel 10 eingreift. Auf diese Weise kann der Stellhebel 12 den Verriegelungshebel 10 verschwenken, beispielsweise in die Positionen "verriegelt" oder "entriegelt" überführen und hierdurch die Kindersicherungsfunktion umsetzen.For this purpose, the adjusting
Man erkennt, dass der zusätzliche Antrieb 7, 8 bei in Stellung "verriegelt" befindlichem Betätigungshebelwerk 12 einen Sensor beaufschlagt. Bei diesem Sensor kann es sich um einen Kindersicherungssensor bzw. Kindersicherungsschalter handeln. Nur dann, wenn der fragliche Sensor beaufschlagt wird, wird das einleitend bereits angesprochene Öffnungssignal erzeugt, welches dazu führt, dass der Antrieb 4, 5 zum elektrischen Öffnen des Gesperres bestromt wird. Das heißt, der elektrische Öffnungsvorgang des Gesperres setzt voraus, dass ein Signal des Sensors seitens einer nicht dargestellten Steuereinheit registriert wird, an welche der Sensor angeschlossen ist.It can be seen that the
Die Beaufschlagung des Sensors setzt voraus, dass der zusätzliche Antrieb 7, 8 von seiner Position "aus bzw. Kindersicherung aus" entsprechend der Darstellung in der
Auf diese Weise stellt die Erfindung sicher, dass einerseits der Verriegelungshebel 10 definitiv seine Position "verriegelt" einnimmt bzw. beibehält, weil die mit dem Übergang von der Position "aus" zur Stellung "ein" verbundene Gegenuhrzeigersinnbewegung der Abtriebsscheibe 8 des zusätzlichen Antriebes 7, 8 dazu korrespondiert, dass der Verriegelungshebel 10 um seine Achse bedarfsweise im Uhrzeigersinn verschwenkt wird, wie dies beim Übergang von der
Nach Erreichen der Position "ein" entsprechend der
