Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism and a closing / opening device, which has at least one drive and a lever drive.
- Cinching / opening devices are generally used for convenience in motor vehicles and serve to either transfer a vehicle door to its fully closed position (main closed position) or to provide for its opening. Due to the not inconsiderable mechanical and cost overhead Zuzieh- / opening devices are nowadays mainly reserved for high-priced automobiles. However, since total safety can also be increased by means of closing aids, an integrated equipment is increasingly being promoted.
- the lever drive is complicated and costly constructed as part of the closing / opening device.
- the entire lever drive must be moved. This is often not very comfortable for an operator.
- children, for example, can hardly interrupt the closing process. This is where the invention starts.
- the invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described above so that the possibility of energy-saving interruption of its function is given with a simple and cost-effective construction of the closing / opening device.
- the lever drive is usually found in engaged position, namely, when the release lever is not actuated. On the other hand, if the release lever experiences an actuation, the lever drive is thereby transferred to the disengaged position and at the same time the mechanical operative connection between the drive and the locking mechanism is interrupted. As a result, the drive can not work (more) on the ratchet and the closing / opening device is switched as it were ineffective.
- the lever drive is designed in two parts. It generally has a support lever and a drive lever. Both the support lever and the drive lever are usually designed as Einarmhebel and equipped at one end with a rotation axis.
- the axis of rotation for the support lever is usually in or on a lock case, which receives the essential elements of the motor vehicle door lock.
- the off-axis free end of the support lever is held between on the one hand the (unactuated) release lever and on the other hand the drive lever.
- the drive lever and the release lever each be equipped with stop pins that receive the support lever between them.
- the support lever is generally equipped with an associated spring.
- This spring ensures that the support lever is acted upon, with a force in the direction of contact with the drive lever. As a result, it is ensured that the support lever as it were supports or holds the drive lever, in a position that allows the drive lever to attack the ratchet respectively a local catch of the locking mechanism.
- the engaged state of the lever drive corresponds.
- the drive lever is ejected as it were. That is, the drive lever is designed ausierd in disengaged position of the lever drive itself.
- the drive lever is generally connected at one end to the drive and interacts with the other end of the locking mechanism.
- the Caribbeanausdorfde effect is now preferably achieved in that the drive lever has a stop surface with pre-cut or chamfer at its locking-side end.
- the precut or the chamfer is designed so that an already obligatory and the locking associated spring ensures that the drive lever is ejected immediately when the supporting or blocking action of the support lever is omitted because the release lever has been actuated.
- the release lever engages over both the support lever and the drive lever, in its unactuated position.
- the support lever and the drive lever do not become (more) fixed by the release lever or held.
- the rotary latch acting on the stop surface with precut and acted upon by the spring in the direction "open” can eject the drive lever.
- the drive lever with its stop surface is not (more) on the locking mechanism and the closing / opening device can also develop no effect.
- the lever drive is in its disengaged position.
- the release lever effecting its operation by means of its actuation is generally a lock operating lever.
- This lock operating lever may be configured as an inner operating lever and / or an outer operating lever and / or an operating main lever.
- Actuator main lever means an operating lever in the context of the invention, on which both the internal operating lever and the external operating lever work.
- the inside operating lever is mechanically connected to an inside operation and a inside door handle, respectively, whereas an outside door handle interacts with the outside operating lever.
- an action on the inside door handle and / or the outside door handle ensures that the lever drive is disengaged and the drive lever or a drive pawl realized at this point is released from the locking mechanism because it is itself ejected.
- the locking mechanism returns to its prelocking position when the vehicle door lock as a whole is in the "locked” position or even assumes the open position. This applies in the event that the motor vehicle door lock is in the "unlocked” position.
- lock operating lever is sufficient to disengage the lever drive and thus the mechanical operative connection from the drive to the locking mechanism.
- This process is usually associated with an emergency interruption, for example, when a closing process, an object or a hand is trapped between the door and body.
- a motor vehicle door lock is shown, which is composed essentially of a motor vehicle door lock 1 and a cooperating and only hinted locking bolt 2.
- the motor vehicle door lock 1 or the motor vehicle door lock is with a conventional locking mechanism 3, 4 equipped, which is composed of a rotary latch 3 and a pawl 4.
- a schematically indicated drive 5 is realized, which together with a lever drive 6, 7, 8 defines a closing / opening device 5 to 8.
- the closing / opening device 5 to 8 is designed in the context of the embodiment as a closing aid 5 to 8.
- Fig. 1 As part of the presentation after Fig. 1 is the lever drive 6, 7, 8 in the engaged position and provides a mechanical operative connection between the drive 5 and the locking mechanism 3, 4 ago.
- a pulling action on a transmission lever 6 with the aid of a Bowden cable provided at the end of the drive 5 actually ensures in the direction of the arrow Fig. 1 that a connected to the transmission lever 6 drive lever 7 abuts against the rotary latch 3 of the locking mechanism 3, 4.
- the rotary latch 3 is moved in the counterclockwise direction, as indicated by an associated arrow.
- a differently shaped connecting means between drive 5 and transmission lever 6 can be used.
- Fig. 1 is the ratchet 3, 4 in the prelocking or pre-locking position, in which the pawl 4 has fallen into a pre-catch of the rotary latch 3 as is common practice.
- This position has been initiated or achieved that the locking pin 2 is retracted in an inlet mouth of the rotary latch 3 when closing the vehicle door and the rotary latch 3 has pivoted to the pre-locking position in the counterclockwise direction.
- the drive 5 is acted upon as described.
- the drive lever 7 is guided by means of a support lever 8, so that the two stop surfaces 7a, 3a on the one hand on the drive lever 7 and on the other hand on the catch 3 remain engaged.
- the drive lever 7 and the support lever 8 are each formed as a Einarmhebel.
- the drive lever 7 is mounted with its one end in a rotation axis on the transmission lever 6. Its other end has the already mentioned stop surface 7a.
- the support lever 8 finds at its one end a pivot bearing in a rotation axis, which is defined in a lock case 9. His other free end is held on the one hand between a trigger lever 10 and on the other hand, the drive lever 7.
- both the drive lever 7 and the release lever 10 each have stop pins 11, 12.
- the stop pin 11 on the drive lever 7 and on the other hand the stop pin 12 on the release lever 10 of the support lever 8 is received, in the "unactuated or not actuated "of the trigger lever 10.
- the basic structure still includes a merely indicated spring, which acts on the support lever or blocking lever 8 with a force in the direction of engagement with the drive lever 7.
- Another spring which is not explicitly shown, ensures that the locking mechanism 3, 4 or its rotary latch 3 is acted upon in the direction of the "open" position.
- a clockwise force acting on the rotary latch 3 corresponds (see the arrow in FIG Fig. 2 ). That is, the spring acts in the opposite direction to the movement of the rotary latch 3 during the closing operation (counterclockwise).
- Fig. 1 is the vehicle door lock 1 in the pre-locking position, wherein the release lever 10 is not actuated.
- This pre-locking position of the locking mechanism 3, 4 has been taken because the locking pin 2 is retracted into an inlet mouth of the rotary latch 3 and the rotary latch 3 has pivoted counterclockwise until the in Fig. 1 shown position has been reached in pre-engaged position pawl 4. Once this is the case, the drive 5 comes into action.
- the drive 5 operates on, for example, an output-side Bowden cable or generally a flexible connecting element on the transmission lever 6 and acts on this with a vertical force at one end down, as indicated by a local arrow.
- the other end of the executed as Zweiarmhebel transmission lever 6 is moved upward, which then also applies to the rotatably mounted on the transmission lever 6 drive lever 7.
- the abutment surface 7a of the drive lever 7 strikes directly on the rotary latch 3 (abutment surface 3a) and transfers the rotary latch 3 counterclockwise into its main latching position (cf. Fig. 3 ).
- the motor or drive 5 is stopped. This is the usual functionality of the Zuziehfunktion.
- the release lever 10 As a result, the release lever 10, the support lever 8 and the drive lever 7 no longer overlap and therefore no longer hold in position, as the Fig. 2 reflects. For as soon as the release lever 10 is actuated, this corresponds to the disengaged position of the lever drive 6, 7, 8. In this disengaged position of the lever drive 6, 7, 8, the drive lever 7 is ejected itself.
- the stop surface 7a of the drive lever 7 is equipped with a precut or bevel, which rotatably (clockwise) on the rotary latch 3 working said spring ensures that the drive lever 7 from the locking mechanism 3, 4 and the stop surface 3a on the Rotary latch 3 is pushed away.
- the support lever 8 is taken, against the force of the spring. That's it attributed that the spring force of the locking member 3, 4 associated spring exceeds that force that lives in the spring of the support lever 8 and in addition the door seal pressure, the rotary latch 3 presses.
- the drive lever 7 is thus issued upon actuation of the release lever 10 by the force of the locking mechanism 3, 4 associated spring, the back pressure of the door and under an optional entrainment of the support lever 8.
- the drive lever 7 is therefore formed aus-d even as soon as the lever drive 6, 7, 8 assumes its disengaged position when the trigger lever 10 is actuated.
- the actuation of the release lever 10 is - as mentioned - initiated by applying an internal door handle and / or outside door handle.

Description
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit einem Gesperre sowie einer Zuzieh-/Öffnungseinrichtung, welche wenigstens einen Antrieb und einen Hebeltrieb aufweist.The invention relates to a motor vehicle door lock, with a locking mechanism and a closing / opening device, which has at least one drive and a lever drive.
Zuzieh-/Öffnungseinrichtungen werden im Allgemeinen aus Komfortgründen bei Kraftfahrzeugen eingesetzt und dienen dazu, entweder eine Kraftfahrzeugtür in ihre vollständig geschlossene Position (Hauptschließstellung) zu überführen oder für deren Öffnung zu sorgen. Aufgrund des nicht unbeträchtlichen mechanischen und kostenmäßigen Aufwandes sind Zuzieh-/Öffnungseinrichtungen heutzutage überwiegend hochpreisigen Automobilien vorbehalten. Da sich durch Zuziehhilfen insgesamt aber auch die Sicherheit erhöhen lässt, wird zunehmend eine durchgängige Ausrüstung propagiert.Cinching / opening devices are generally used for convenience in motor vehicles and serve to either transfer a vehicle door to its fully closed position (main closed position) or to provide for its opening. Due to the not inconsiderable mechanical and cost overhead Zuzieh- / opening devices are nowadays mainly reserved for high-priced automobiles. However, since total safety can also be increased by means of closing aids, an integrated equipment is increasingly being promoted.
Bei bekannten Ausgestaltungen, wie sie beispielsweise in der
Der Erfindung liegt das technische Problem zugrunde, einen Kraftfahrzeugtürverschluss der eingangs beschriebenen Ausgestaltung so weiter zu entwickeln, dass bei einfachem und kostengünstigem Aufbau der Zuzieh-/Öffnungseinrichtung zugleich die Möglichkeit zur kraftsparenden Unterbrechung seiner Funktion gegebenen ist.The invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described above so that the possibility of energy-saving interruption of its function is given with a simple and cost-effective construction of the closing / opening device.
Zur Lösung dieser technischen Problemstellung ist bei einem gattungsgemäßen Kraftfahrzeugtürverschluss vorgesehen, dass der Hebeltrieb in eingekuppelter Stellung durch einen unbetätigten Auslösehebel gehalten wird und seine ausgekuppelte Stellung bei Betätigung des Auslösehebels einnimmt.To solve this technical problem is provided in a generic motor vehicle door lock that the lever drive is held in the engaged position by an unactuated release lever and occupies its disengaged position upon actuation of the release lever.
In der eingekuppelten Stellung liegt eine mechanische Wirkverbindung zwischen dem Antrieb und dem Gesperre vor. Das heißt, der Antrieb kann über den Hebeltrieb das Gesperre in die gewünschte Position (meistens die Hauptschließstellung oder die Hauptraststellung) überführen. In der ausgekuppelten Stellung des Hebeltriebes ist die mechanische Wirkverbindung dagegen unterbrochen. Erfindungsgemäß sorgt nun der Auslösehebel für den Wechsel des Hebeltriebes von der eingekuppelten Stellung in die ausgekuppelte Stellung.In the engaged position there is a mechanical operative connection between the drive and the locking mechanism. This means that the drive can use the lever drive to transfer the locking mechanism into the desired position (usually the main locking position or the main locking position). In the disengaged position of the lever drive, however, the mechanical operative connection is interrupted. According to the invention now provides the release lever for the change of the lever drive from the engaged position to the disengaged position.
Tatsächlich findet sich der Hebeltrieb üblicherweise in eingekuppelter Stellung, wenn nämlich der Auslösehebel nicht betätigt wird. Erfährt der Auslösehebel dagegen eine Betätigung, so wird hierdurch der Hebeltrieb in die ausgekuppelte Stellung überführt und zugleich die mechanische Wirkverbindung zwischen dem Antrieb und dem Gesperre unterbrochen. Als Folge hiervon kann der Antrieb nicht (mehr) auf das Gesperre arbeiten und ist die Zuzieh-/Öffnungseinrichtung gleichsam wirkungslos geschaltet. In der Regel ist der Hebeltrieb zweiteilig ausgebildet. Er verfügt im Allgemeinen über einen Stützhebel und einen Antriebshebel. Sowohl der Stützhebel als auch der Antriebshebel sind meistens als Einarmhebel ausgestaltet und an ihrem einen Ende mit einer Drehachse ausgerüstet.In fact, the lever drive is usually found in engaged position, namely, when the release lever is not actuated. On the other hand, if the release lever experiences an actuation, the lever drive is thereby transferred to the disengaged position and at the same time the mechanical operative connection between the drive and the locking mechanism is interrupted. As a result, the drive can not work (more) on the ratchet and the closing / opening device is switched as it were ineffective. As a rule, the lever drive is designed in two parts. It generally has a support lever and a drive lever. Both the support lever and the drive lever are usually designed as Einarmhebel and equipped at one end with a rotation axis.
Dabei findet sich die Drehachse für den Stützhebel in der Regel in oder an einem Schlosskasten, welcher die wesentlichen Elemente des Kraftfahrzeugtürschlosses aufnimmt. Das achsferne freie Ende des Stützhebels wird zwischen einerseits dem (unbetätigten) Auslösehebel und andererseits dem Antriebshebel gehalten. Zu diesem Zweck mögen der Antriebshebel und der Auslösehebel jeweils mit Anschlagzapfen ausgerüstet sein, die den Stützhebel zwischen sich aufnehmen.In this case, the axis of rotation for the support lever is usually in or on a lock case, which receives the essential elements of the motor vehicle door lock. The off-axis free end of the support lever is held between on the one hand the (unactuated) release lever and on the other hand the drive lever. For this purpose like the drive lever and the release lever each be equipped with stop pins that receive the support lever between them.
Des Weiteren ist der Stützhebel im Allgemeinen mit einer zugeordneten Feder ausgerüstet. Diese Feder sorgt dafür, dass der Stützhebel beaufschlagt wird, und zwar mit einer Kraft in Richtung Anlage am Antriebshebel. Dadurch wird insgesamt gewährleistet, dass der Stützhebel den Antriebshebel gleichsam abstützt bzw. festhält, und zwar in einer Position, die es dem Antriebshebel ermöglicht, am Gesperre respektive einer dortigen Drehfalle des Gesperres angreifen zu können. Hierzu korrespondiert der eingekuppelte Zustand des Hebeltriebes.Furthermore, the support lever is generally equipped with an associated spring. This spring ensures that the support lever is acted upon, with a force in the direction of contact with the drive lever. As a result, it is ensured that the support lever as it were supports or holds the drive lever, in a position that allows the drive lever to attack the ratchet respectively a local catch of the locking mechanism. For this purpose, the engaged state of the lever drive corresponds.
Ist jedoch der Hebeltrieb ausgekuppelt, weil der Auslösehebel betätigt worden ist, so wird der Antriebshebel gleichsam selbst ausgeworfen. Das heißt, der Antriebshebel ist in ausgekuppelter Stellung des Hebeltriebs selbst auswerfend ausgebildet. Dazu ist der Antriebshebel im Allgemeinen mit seinem einen Ende an den Antrieb angeschlossen und wechselwirkt mit seinem anderen Ende mit dem Gesperre. Die selbstauswerfende Wirkung wird nun vorzugsweise dadurch erreicht, dass der Antriebshebel an seinem gesperreseitigen Ende eine Anschlagfläche mit Vorschnitt oder Fase aufweist.However, if the lever drive is disengaged because the release lever has been actuated, the drive lever is ejected as it were. That is, the drive lever is designed auswerfend in disengaged position of the lever drive itself. For this purpose, the drive lever is generally connected at one end to the drive and interacts with the other end of the locking mechanism. The Selbstauswerfende effect is now preferably achieved in that the drive lever has a stop surface with pre-cut or chamfer at its locking-side end.
Dabei ist der Vorschnitt bzw. die Fase so gestaltet, dass eine ohnehin meist obligatorische und dem Gesperre zugeordnete Feder dafür sorgt, dass der Antriebshebel unmittelbar dann ausgeworfen wird, wenn die abstützende oder blockierende Wirkung des Stützhebels wegfällt, weil der Auslösehebel betätigt worden ist.In this case, the precut or the chamfer is designed so that an already obligatory and the locking associated spring ensures that the drive lever is ejected immediately when the supporting or blocking action of the support lever is omitted because the release lever has been actuated.
Im Allgemeinen übergreift der Auslösehebel sowohl den Stützhebel als auch den Antriebshebel, und zwar in seiner unbetätigten Stellung. Wenn jedoch der Auslösehebel betätigt wird, werden der Stützhebel und der Antriebshebel nicht (mehr) von dem Auslösehebel fixiert bzw. festgehalten. Als Folge hiervon kann die an der Anschlagfläche mit Vorschnitt angreifende und von der Feder in Richtung "offen" beaufschlagte Drehfalle den Antriebshebel auswerfen.In general, the release lever engages over both the support lever and the drive lever, in its unactuated position. However, when the trip lever is operated, the support lever and the drive lever do not become (more) fixed by the release lever or held. As a result, the rotary latch acting on the stop surface with precut and acted upon by the spring in the direction "open" can eject the drive lever.
Dadurch liegt der Antriebshebel mit seiner Anschlagfläche nicht (mehr) am Gesperre an und kann die Zuzieh-/Öffnungseinrichtung auch keine Wirkung mehr entfalten. Der Hebeltrieb befindet sich in seiner ausgekuppelten Stellung.As a result, the drive lever with its stop surface is not (more) on the locking mechanism and the closing / opening device can also develop no effect. The lever drive is in its disengaged position.
Bei dem die Auskupplung durch seine Betätigung bewirkenden Auslösehebel handelt es sich im Allgemeinen um einen Schlossbetätigungshebel. Dieser Schlossbetätigungshebel kann als Innenbetätigungshebel und/oder Außenbetätigungshebel und/oder Betätigungshaupthebel ausgestaltet sein. Betätigungshaupthebel meint dabei einen Betätigungshebel im Rahmen der Erfindung, auf welchen sowohl der Innenbetätigungshebel als auch der Außenbetätigungshebel arbeiten. Wie üblich ist der Innenbetätigungshebel an eine Innenbetätigung respektive einen Türinnengriff mechanisch angeschlossen, wohingegen ein Türaußengriff mit dem Außenbetätigungshebel wechselwirkt.The release lever effecting its operation by means of its actuation is generally a lock operating lever. This lock operating lever may be configured as an inner operating lever and / or an outer operating lever and / or an operating main lever. Actuator main lever means an operating lever in the context of the invention, on which both the internal operating lever and the external operating lever work. As usual, the inside operating lever is mechanically connected to an inside operation and a inside door handle, respectively, whereas an outside door handle interacts with the outside operating lever.
In jedem Fall sorgt eine Beaufschlagung des Türinnengriffes und/oder des Türaußengriffes dafür, dass der Hebeltrieb ausgekuppelt wird und der Antriebshebel bzw. eine an dieser Stelle realisierte Antriebsklinke von dem Gesperre frei kommt, weil er bzw. sie selbst ausgeworfen wird. Als Folge hiervon geht das Gesperre in seine Vorschließstellung zurück, wenn sich das Kraftfahrzeugtürschloss insgesamt in der Position "verriegelt" befindet oder nimmt sogar die Offenstellung ein. Das gilt für den Fall, dass sich das Kraftfahrzeugtürschloss in der Position "entriegelt" befindet.In any case, an action on the inside door handle and / or the outside door handle ensures that the lever drive is disengaged and the drive lever or a drive pawl realized at this point is released from the locking mechanism because it is itself ejected. As a result, the locking mechanism returns to its prelocking position when the vehicle door lock as a whole is in the "locked" position or even assumes the open position. This applies in the event that the motor vehicle door lock is in the "unlocked" position.
In sämtlichen Fällen reicht die simple Beaufschlagung des Auslösehebels bzw. des an dieser Stelle realisierten Schlossbetätigungshebels vollständig aus, um den Hebeltrieb auszukuppeln und folglich die mechanische Wirkverbindung vom Antrieb bis zum Gesperre zu unterbrechen. Dieser Vorgang geht meist mit einer Notunterbrechung einher, wenn beispielsweise bei einem Zuziehvorgang ein Gegenstand oder eine Hand zwischen Tür und Karosserie eingeklemmt ist.In all cases, the simple loading of the release lever or realized at this point lock operating lever is sufficient to disengage the lever drive and thus the mechanical operative connection from the drive to the locking mechanism. This process is usually associated with an emergency interruption, for example, when a closing process, an object or a hand is trapped between the door and body.
Dann führt eine unmittelbare Betätigung des Türaußengriffes und/oder Türinnengriffes dazu, dass der Zuziehvorgang augenblicklich unterbrochen wird und je nach Stellung des Kraftfahrzeugtürschlosses (entriegelt oder verriegelt) die zugehörige Kraftfahrzeugtür im Anschluss daran vollständig geöffnet werden kann, zumindest eine weitere Zuziehbewegung (nicht) mehr erfolgt. Das Gleiche gilt prinzipiell für den Fall, dass anstelle in zuziehendem Sinne in öffnendem Sinne auf die Kraftfahrzeugtür gearbeitet wird. Ingesamt sind nur minimale Bedienkräfte erforderlich, die problemlos auch von einem Kind aufgebracht werden können. Hierin sind die wesentlichen Vorteile zu sehen.Then, an immediate operation of the outside door handle and / or inside door handle causes the closing process is interrupted immediately and depending on the position of the motor vehicle door lock (unlocked or locked), the associated motor vehicle door can be completely opened thereafter, at least one further Zuziehbewegung (not) more , The same applies in principle for the case that is worked in the opening sense of the motor vehicle door instead of pulling in the sense. All in all, only minimal operating forces are required, which can also be easily applied by a child. Here are the main benefits.

Sein anderes freies Ende wird einerseits zwischen einem Auslösehebel 10 und andererseits dem Antriebshebel 7 gehalten. Zu diesem Zweck verfügen sowohl der Antriebshebel 7 als auch der Auslösehebel 10 jeweils über Anschlagzapfen 11, 12. Zwischen einerseits dem Anschlagzapfen 11 am Antriebshebel 7 und andererseits dem Anschlagzapfen 12 am Auslösehebel 10 wird der Stützhebel 8 aufgenommen, und zwar in der Position "unbetätigt oder nicht betätigt" des Auslösehebels 10.The
Dagegen sind der Antriebshebel 7 und auch der Stützhebel 8 von dem Auslösehebel 10 frei, wenn dieser betätigt wird. Diese Betätigung korrespondiert zu einem Verschwenken des Auslösehebels 10 um seine im Schlosskasten 9 angeordnete Drehachse D im Uhrzeigersinn, wie dies in der
Zum grundsätzlichen Aufbau gehört noch eine lediglich angedeutete Feder, die den Stützhebel bzw. Blockierhebel 8 mit einer Kraft in Richtung Anlage am Antriebshebel 7 beaufschlagt. Eine weitere Feder, die nicht ausdrücklich dargestellt ist, sorgt dafür, dass das Gesperre 3, 4 bzw. seine Drehfalle 3 in Richtung der Stellung "offen" beaufschlagt wird. Hierzu korrespondiert eine im Uhrzeigersinn angreifende Kraft an der Drehfalle 3 (vgl. den Pfeil in
Die Funktionsweise ist wie folgt. In der
Der Antrieb 5 arbeitet über beispielsweise einen ausgangsseitigen Bowdenzug oder allgemein ein flexibles Verbindungselement auf den Übertragungshebel 6 und beaufschlagt diesen mit einer Vertikalkraft an seinem einen Ende nach unten, wie dies ein dortiger Pfeil andeutet. Dadurch wird das andere Ende des als Zweiarmhebel ausgeführten Übertragungshebels 6 nach oben bewegt, was dann auch für den auf dem Übertragungshebel 6 drehbar gelagerten Antriebshebel 7 gilt. Als Folge hiervon schlägt die Anschlagfläche 7a des Antriebshebels 7 unmittelbar an der Drehfalle 3 an (Anschlagfläche 3a) und überführt die Drehfalle 3 im Gegenuhrzeigersinn in ihre Hauptraststellung (vgl.
Als Folge hiervon kann der Auslösehebel 10 den Stützhebel 8 und auch den Antriebshebel 7 nicht mehr übergreifen und folglich nicht mehr in ihrer Position halten, wie dies die
Dies geschieht dergestalt, dass der mit seinem einen Ende an den Antrieb 5 angeschlossene Antriebshebel 7 und mit seinem anderen Ende mit dem Gesperre 3, 4 wechselwirkende Antriebshebel 7 durch die Kraft des Gesperres 3, 4 ausgeworfen wird. Das heißt, die dem Gesperre 3, 4 zugeordnete Feder beaufschlagt die Drehfalle 3 (im Uhrzeigersinn) in Richtung ihrer Stellung "offen".This is done in such a way that the
Dadurch, dass die Anschlagfläche 7a des Antriebshebels 7 mit einem Vorschnitt oder einer Fase ausgerüstet ist, sorgt die rotativ (im Uhrzeigersinn) auf die Drehfalle 3 arbeitende besagte Feder dafür, dass der Antriebshebel 7 vom Gesperre 3, 4 bzw. der Anschlagfläche 3a an der Drehfalle 3 weggedrückt wird. Bei diesem Vorgang des Selbstauswerfens wird zugleich der Stützhebel 8 mitgenommen, und zwar gegen die Kraft dessen Feder. Das lässt sich darauf zurückführen, dass die Federkraft der dem Gesperre 3, 4 zugeordneten Feder diejenige Kraft übersteigt, die der Feder des Stützhebels 8 inne wohnt und zusätzlich der Türdichtungsdruck die Drehfalle 3 aufdrückt.Characterized in that the stop surface 7a of the
Insgesamt wird der Antriebshebel 7 bei Betätigung des Auslösehebels 10 also durch die Kraft der dem Gesperre 3, 4 zugehörigen Feder, dem Türgegendruck sowie unter einer optionalen Mitnahme des Stützhebels 8 ausgestellt. Der Antriebshebel 7 ist also selbst auswerfend ausgebildet, sobald der Hebeltrieb 6, 7, 8 seine ausgekuppelte Stellung bei betätigtem Auslösehebel 10 einnimmt. Die Betätigung des Auslösehebels 10 wird - wie gesagt - durch Beaufschlagung eines Innentürgriffs und/oder Außentürgriffs initiiert.Overall, the
