Abstract

The invention relates to a lock, especially for the doors, flaps or the like, of motor vehicles, comprising a rotating latch (11) into which a closing element (20) is inserted, when the door is closed. Said rotating latch (11) is pivoted out of an open position into a main locking position, via a pre-locking position. Said lock also comprises a catch (21) which, in the pre-locking position, engages in a pre-stop notch provided on the rotating latch (11), and in the main locking position, engages in the main stop notch (14) positioned on the rotating latch. The inventive lock also comprises motor-driven closing/opening auxiliary means for the door, having a drive part (29) and a drive device (30) with at least two output elements (37, 38) which act on the rotating latch (11) or the catch (21). Said lock further comprises control means for positioning the closing and opening auxiliary means in an active or passive position, wherein the output elements (37, 38) are continuously coupled to the drive part (29) in such a way that the two output elements (37, 38) are displaced in an isochronous manner when the drive part (29) is switched on.

Description

Schloß, insbesondere für Kraftfahrzeugtüren, -klappen od. dgl Lock, in particular for motor vehicle doors, flaps or the like
Die Erfindung richtet sich auf ein Schloß der im Oberbegriff des Patentanspruches 1 genannten Art, wie es z.B. bei Kraftfahrzeugtüren oder -klappen zum Einsatz kommt. Die Drehfalle besitzt außer einer Vorrast auch noch eine Hauptrast, in welche eine Klinke einfällt. Beim schließen einer geöffneten Tür bleibt manchmal ein Spalt offen, weil die Klinke nur in die Vorrast der Drehfalle einfällt. Dann bleibt die Drehfalle in ihrer Vorrastlage stehen. Um den Spalt zu schließen, werden motorische Schließhilfen verwendet, die an der Drehfalle angreifen, und die die Drehfalle in eine endgültige Lage weiterbewegen, in der die Klinke in die Hauptrast einfällt. Diese endgültige Lage wird im nachfolgenden „Hauptrastlage" genannt.The invention relates to a lock of the type mentioned in the preamble of claim 1, as it e.g. is used for motor vehicle doors or flaps. In addition to a preliminary catch, the rotary latch also has a main catch, into which a latch engages. When closing an open door, a gap sometimes remains open because the latch only engages in the latch's latch. Then the rotary latch remains in its pre-locked position. In order to close the gap, motorized locking aids are used which engage the rotary latch and which move the rotary latch into a final position in which the latch engages in the main catch. This final position is referred to below as the "main rest position".
Ein Schloß der obengenannten Art ist aus der WO99/49159 bekannt. Darin ist ein Schloß beschrieben, bei dem an einem Motorantrieb ein Getriebe angeordnet ist, das über zwei Abtriebswege verfügt. Der erste Abtriebsweg kann dabei als Schließhilfe auf die Drehfalle, und der zweite Abtriebsweg als Öffnungshilfe auf die Klinke einwirken. An dem Getriebe ist ein Übertragungsglied vorgesehen, über welches jeweils ein Abtriebsweg wirksam gesetzt werden kann, während der andere Abtriebsweg inaktiv gesetzt wird, je nachdem ob der Antrieb als Öffnungs- oder Schließhilfe genutzt werden soll.A lock of the type mentioned above is known from WO99 / 49159. This describes a lock in which a gear is arranged on a motor drive and has two output paths. The first output path can act as a closing aid on the catch and the second output path as an opening aid on the latch. A transmission element is provided on the transmission, via which one output path can be set effectively, while the other output path is set inactive, depending on whether the drive is to be used as an opening or closing aid.
Von Nachteil bei diesem Schloß ist, dass zur Umstellung des Übertragungsgliedes ein Schaltwerk und ein weiterer Antrieb benötigt wird, wodurch das Schloß recht aufwendig in der Herstellung ist. Aus der WO 98/27301 A2 ist ferner ein Schloß mit einer motorischen Schließ- undThe disadvantage of this lock is that a switching mechanism and a further drive are required to convert the transmission element, which means that the lock is quite complex to manufacture. From WO 98/27301 A2 is also a lock with a motorized locking and

In der Funktion als Schließhilfe, in der zweiten Drehrichtung des Antriebs, wird nach einem Zuschlagen der Tür, über den zweiten Abtriebsweg eine Zuziehbewegung auf die Drehfalle übertragen, während dieOpening movement of the rotary latch further supported. In the function as a closing aid, in the second direction of rotation of the drive, after the door slams shut, a closing movement is transferred to the rotary latch via the second output path, while the

Von Nachteil bei diesem Schloß ist es, daß zur zeitversetzten Ankopplung der beiden Abtriebswege an den Antrieb aufwendige Kopplungs- und Steuermittel notwendig sind, um die Ankopplung zum exakt benötigten Zeitpunkt zu ermöglichen. Hierdurch ist dieses Schloß in der Herstellung relativ kostenintensiv.The disadvantage of this lock is that complex coupling and control means are required for the time-delayed coupling of the two output paths to the drive in order to enable the coupling at the exact time required. As a result, this lock is relatively expensive to manufacture.
Aufgabe der Erfindung ist es, ein Schloß der eingangs genannten Art zu entwickeln, das zuverlässig arbeitet und die oben genannten Nachteile vermeidet. Dieses wird erfindungs gemäß durch die im kennzeichnenden Teil des Anspruches 1 genannten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The object of the invention is to develop a lock of the type mentioned that works reliably and avoids the disadvantages mentioned above. This is achieved according to the Invention by the measures mentioned in the characterizing part of claim 1, which have the following special meaning.
Die Besonderheit der dort beschriebenen Maßnahmen liegt darin, an dem Getriebe zwei Abtriebswege vorzusehen, die ständig an den Antrieb angekuppelt sind. Durch diese Maßnahme ist das erfindungsgemäße Schloß günstig herzustellen, und durch seinen einfachen Aufbau sehr zuverlässig.The peculiarity of the measures described there is to provide two output ways on the transmission, which are constantly coupled to the drive. This measure makes the lock according to the invention inexpensive to manufacture and very reliable due to its simple construction.
Das Wirksam- bzw. Unwirksamsetzen der Abtriebswege erfolgt lediglich über die Drehrichtung des Antriebes, der als motorische Öffnungs- oder Schließhilfe dient. Durch diese Maßnahme wird die Verwendung eines Übertragungsglieds und eines Schaltwerks mit zusätzlichem Antrieb bzw. die Verwendung von Kopplungsmitteln zur Zuschaltung eines Abtriebsweges überflüssig. Günstig gemäß Anspruch 3 ist es, wenn die Abtriebselemente bei eingeschaltetem Antriebsteil in entgegengesetzte Richtungen laufen. Beide Abtriebselemente sind dabei in Bezug auf ihre Lagerung an den Drehachsen und ihre Geometrie derart konfiguriert, dass sich beide Abtriebselemente auf ihren jeweiligen Bewegungswegen nicht kreuzen. Von Vorteil ist gemäß Anspruch 4 ferner, wenn das Getriebe zwei Achsen umfasst und an einer jeden dieser Achsen jeweils ein Abtriebselement angeordnet ist. Über Zahnräder unterschiedlichen Durchmessers, welche ebenfalls an diesen Achsen angeordnet sind, können dabei vorteilhafterweise den Abtriebselementen unterschiedliche Antriebsmomente zugeordnet werden, so dass auf die speziellen Anforderungen bei einer Funktion als Öffnungs- bzw. als Zuziehhilfe eingegangen werden kann.The output paths only become effective or ineffective via the direction of rotation of the drive, which serves as a motorized opening or closing aid. This measure makes the use of a transmission element and a switching mechanism with additional drive or the use of coupling means for connecting an output path superfluous. It is expedient according to claim 3 if the output elements run in opposite directions when the drive part is switched on. Both output elements are configured with regard to their mounting on the axes of rotation and their geometry such that both output elements do not cross on their respective paths of movement. It is also advantageous according to claim 4 if the transmission comprises two axles and an output element is arranged on each of these axles. Different drive torques can advantageously be assigned to the output elements via gearwheels of different diameters, which are also arranged on these axes, so that the special requirements for a function as an opening or closing aid can be addressed.
Das Abtriebselement, welches als Öffnungshilfe fungiert, kann z.B. ein Koppelglied umfassen, über welches bei einer Bewegung des Abtriebselementes die Klinke aus der Hauptrast an der Drehfalle ausgehoben werden kann.The output element, which acts as an opening aid, can e.g. comprise a coupling member, by means of which the pawl can be lifted out of the main catch on the rotary latch when the output element moves.
Von Vorteil ist es ebenfalls, wenn an der Flank ^j der Klinge ein Sperrelemen^ arigeordnet ist, welches den Bewegungswea des Kjoppelgliedes oder Abtriebselementes, welches als Öffnungshilfe fungiert, in ffnungshilferichtung begrenzt. Fährt das Abtriebseleinent/Koppelglied gegen das Sperrelement und wird es hierdurch gestoppt, so kann dieser Vorgang ein Signal auslösen, welches den motorischen Antrieb des Schlosses abstellt und/oder welches eine Rückstellung des Getriebes über den Motorantrieb in die Grundstellung auslöst. Weitere Steuermittel können demnach für die Rückstellung des Getriebes/der motorischen Öffnungs- /Zuziehhilfe in die Grundstellung nicht mehr notwendig sein.It is also advantageous if a locking element is arranged on the flank of the blade, which limits the movement of the coupling element or output element, which acts as an opening aid, in the opening aid direction. If the output element / coupling element moves against the blocking element and is thereby stopped, this process can trigger a signal which shuts off the motor drive of the lock and / or which triggers a return of the transmission to the basic position via the motor drive. Further control means may therefore no longer be necessary for the return of the transmission / the motorized opening / closing aid to the basic position.
Günstigerweise kann auch das Abtriebselement, welches als Zuziehhilfe fungiert, ein Koppelglied umfassen, das im Betätigungsfall mit einer, an der Drehfalle angeordneten Schulter zusammenwirkt, an die es angreift und über welche es die Drehfalle in Schließrichtung bis in eine Überhublage überführen kann. Wird die Überhublage erreicht und das Koppelglied bzw. das Abtrieb selement hierdurch in seiner Bewegung gestoppt, so kann hierdurch ebenfalls ein Antriebsstopsignal und/oder ein Signal zur Rückstellung des Getriebes bzw. der motorischen Zuzieh-/Öffnungshilfe in dieConveniently, the output element, which acts as a closing aid, can comprise a coupling member which, when actuated, cooperates with a shoulder arranged on the catch, which it engages and via which it can transfer the catch in the closing direction to an overtravel position. If the overstroke position is reached and the coupling element or the output element is thereby stopped in its movement, a drive stop signal and / or a signal can also be hereby Reset the gearbox or the motorized closing / opening aid in the
Grundstellung ausgelöst werden. Auch in diesem Fall können weitere Steuerungsmittel für eine Überführung der motorischen Zuziehhilfe in die Grundstellung dann nicht mehr notwendig sein.Home position can be triggered. In this case too, further control means for moving the motor-driven closing aid to the basic position may then no longer be necessary.
Eine besonders gute Verteilung der Abtriebsmomente auf das erste und zweite Abtriebselement ergibt sich, wenn die Rotationsgeschwindigkeit das Zahnrades a, welches das erste Abtrieb sei ement antreibt und die Rotationsgeschwindigkeit des Zahnrades b, welches das zweite Abtriebselement antreibt, nach folgender Formel im Verhältnis zueinander stehen: Va = Vb x i a/b.A particularly good distribution of the output torques to the first and second output elements is obtained if the rotational speed of the gear wheel a, which drives the first output element, and the rotational speed of the gear wheel b, which drives the second output element, are related to one another according to the following formula: Va = Vb xia / b.
Hierbei ist Va die Rotationsgeschwindigkeit des Zahnrades a und Vb die Rotationsgeschwindigkeit des Zahnrades b. Die Größe i a/b gibt hierbei das Zahnverhältnis der Zahnräder a und b an. Grundvoraussetzung ist, dass Va größer als Vb ist.Here Va is the rotation speed of the gear a and Vb the rotation speed of the gear b. The size i a / b indicates the tooth ratio of the gears a and b. The basic requirement is that Va is larger than Vb.

Neben dem Antriebsmotor 29 und dem Getriebe 30 umfasst das Schloß eine Drehfalle 11, die im verriegelten Zustand des Schlosses über eine Klinke 21 in einer Hauptrastlage festgehalten wird. Die Verriegelung einer Tür an einem gegenüberliegenden Holm etc. eines Kraftfahrzeuges erfolgt dabei über einBe arranged motor vehicle. In addition to the drive motor 29 and the gear 30, the lock includes a rotary latch 11 which is held in a main detent position in the locked state of the lock via a pawl 21. The locking of a door on an opposite spar etc. of a motor vehicle takes place via a
Schließteil 20, welches sich in der Hauptrastlage der Drehfalle 1 1 in einer AufnahmeLocking part 20, which is in the main position of the catch 1 1 in a recording
16 der Drehfalle 11 befindet. Die Drehfalle 11 ist an einem Lagerzapfen 13 schwenkbar angeordnet. Auch die Klinke 21 ist schwenkbar an einen Lagerzapfen 23 angeordnet. An der Drehfalle 11 ist ferner noch eine Hauptrast 14 angeordnet, an der, in der Verriegelungsstellung des Schlosses ein Rasthaken 24 der Klinke 21 angreift, wobei die Hauptrastlage des Schlosses erzeugt wird. Weiterhin ist an der Drehfalle 1 1 eine Vorrast 15 angeordnet, in die in der Vorrastlage des Schlosses der Rasthaken 24 16 of the catch 11 is located. The rotary latch 11 is pivotably arranged on a bearing pin 13. The pawl 21 is also pivotally arranged on a bearing pin 23. Also arranged on the rotary latch 11 is a main catch 14, on which, in the locked position of the lock, a catch hook 24 of the pawl 21 engages, the main catch position of the lock being generated. Furthermore, a preliminary catch 15 is arranged on the rotary latch 11, into which the catch hook 24 is in the preliminary catch position of the lock
Auf die Klinke 21 wirkt eine elastische Kraft in Pfeilrichtung 45 ein, die z.B. durch ein an der Klinke angreifendes Federelement erzeugt wird. Diese Federbelastung 45 belastet die Klinke in Richtung auf die Drehfalle.The pawl 21 is subjected to an elastic force in the direction of arrow 45, which e.g. is generated by a spring element acting on the pawl. This spring load 45 loads the pawl in the direction of the rotary latch.
Auch die Drehfalle 1 1 ist über ein an der Drehfalle 1 1 angeordnetes Mittel federbelastet in Pfeilrichtung 49. Die Federbelastung 49 an der Drehfalle wirkt in Richtung auf die Öffnungsposition der Drehfalle 1 1, wobei die Öffnungsbewegung der Drehfalle 1 1 durch die Federbelastung 49 unterstützt wird.The rotary latch 11 is also spring-loaded in the direction of arrow 49 via a means arranged on the rotary latch 11. The spring load 49 on the rotary latch acts in the direction of the opening position of the rotary latch 11, the opening movement of the rotary latch 11 being supported by the spring load 49 ,
Das Getriebe 30 umfasst folgende Komponenten: An der Welle des Motorantriebs 29 ist eine Schnecke 31 angeordnet, die ein Schneckenrad 32 kämmt. Über die Schnecke 3 1 und das Schneckenrad 32 wird eine Antriebsbewegung vom Antriebsmotor 29 auf die Achse a 33 übetragen. An dieser Achse a 33 ist ferner noch ein Zahnrad a 34 sowie ein Abtrieb sei ement 37 angeordnet, welches in dem vorliegenden Ausführungsbeispiel als Nocken 37' ausgeführt ist. Das Zahnrad a 34 kämmt ein Zahnrad b 35, welches an einer Achse b 36 angeordnet ist. An dieser Achse b 36 ist ferner noch ein Abtriebselement/Koppelglied 38 angeordnet, welches einen Arm 39 umfasst, an dessen freiem Ende ein zur Drehfalle 1 1 hin gerichteter Nocken 39' angeordnet ist. Dieser Nocken 39' kann durch eine Vertiefung 18 an der Drehfalle 1 1 fahren und am Ende dieser Vertiefung 18 gegen eine Schulter 12 laufen, über die der Nocken 39' die Drehfalle 1 1 in Schließrichtung entgegen der Federbelastung 49 bewegen kann. In den Fig. 2 bis 6 sollen nun die Funktionen des erfindungsgemäßen Schlosses beschrieben werden.The gear 30 comprises the following components: A worm 31, which meshes with a worm wheel 32, is arranged on the shaft of the motor drive 29. Via the worm 3 1 and the worm wheel 32, a drive movement is transmitted from the drive motor 29 to the axis a 33. On this axis a 33 there is also a gearwheel 34 and an output element 37, which in the present exemplary embodiment is designed as a cam 37 '. Gear a 34 meshes with gear b 35, which is arranged on an axis b 36. On this axis b 36 there is also an output element / coupling element 38, which comprises an arm 39, at the free end of which a cam 39 'directed towards the rotary latch 11 is arranged. This cam 39 'can travel through a recess 18 on the rotary latch 11 and at the end of this recess 18 run against a shoulder 12, via which the cam 39' can move the rotary latch 11 against the spring load 49 in the closing direction. 2 to 6 the functions of the lock according to the invention will now be described.
Ausgehend von der in Fig. 1 dargestellten Grundstellung der motorischen Öffnungs- /Schließhilfe und der dort dargestellten Hauptrastlage des Schlosses ist in Fig. 2 dargestellt, wie durch eine Betätigung des Antriebsmotors 29 in Öffnungshilfe- Richtung die Klinke 21 und deren Rasthaken/Gegenraststelle 24 aus der Hauptrast 14 der Drehfalle 11 ausgehoben wird. Hierzu wird das Zahnrad a 34 in Richtung des Pfeils 40 bewegt. Das Abtriebselement 37 bzw. der Nocken 37' wird hierdurch mit der Achse a 33 ebenfalls in Pfeilrichtung 40 in eine Drehbewegung versetzt, durch dies ein freies Ende gegen die Flanke 22 an der Klinke 21 fährt und im Zuge seiner ' Schwenkbewegung hierdurch die Klinke 21 entgegen der Federbelastung in Pfeilrichtung 45 aus der Hauptrast 14 an der Drehfalle 1 1 aushebt. Das Zahnrad b 35, welches das Zahnrad a 34 kämmt, wird dabei in entgegengesetzter Drehrichtung in Pfeilrichtung 41 bewegt, und mit diesem das Abtriebselement 38 mit dem Arm 39 und Nocken 39' . Wie aus der Zeichnung ersichtlich ist, ist die Geometrie des Getriebes 30 und der Abtrieb selemente 37, 38 so gewählt, dass das Abtriebselement 38 mit seinem Arm 39 und mit seinem Nocken 39' an sämtlichen an der Achse b 36 angeordneten Elementen frei vorbeilaufen kann.Starting from the basic position of the motorized opening / closing aid shown in FIG. 1 and the main latching position of the lock shown there, FIG. 2 shows how the pawl 21 and its latching hook / counter latching point 24 are actuated in the opening aid direction by actuating the drive motor 29 the main catch 14 of the rotary latch 11 is raised. For this purpose, gear 34 is moved in the direction of arrow 40. The output element 37 or the cam 37 'is thereby also set in a rotational movement with the axis a 33 in the direction of arrow 40, through which a free end moves against the flank 22 on the pawl 21 and in the course of its ' pivoting movement the pawl 21 counteracts this the spring load in the direction of arrow 45 lifts out of the main catch 14 on the rotary latch 11. Gear b 35, which meshes gear a 34, is moved in the opposite direction of rotation in the direction of arrow 41, and with it output element 38 with arm 39 and cams 39 '. As can be seen from the drawing, the geometry of the transmission 30 and the output elements 37, 38 is selected such that the output element 38 with its arm 39 and with its cam 39 'can freely run past all elements arranged on the axis b 36.
Durch das Ausheben der Klinke 21 aus der Hauptraste 14 an der Drehfalle 1 1 wird nun die Drehfalle auf Grund der Federbelastung 49 in Pfeilrichtung 43 verschwenkt, wodurch das Schließteil 20 in Richtung des Pfeils 44 aus der Aufnahme 16 der Drehfalle 1 1 herausbewegt wird. Das Schloß befindet sich nunmehr in seiner Freigabelage und die Tür, Klappe oder der Heckdeckel kann geöffnet werden.By lifting the pawl 21 out of the main catch 14 on the rotary latch 11, the rotary latch is now pivoted in the direction of arrow 43 due to the spring load 49, as a result of which the closing part 20 is moved out of the receptacle 16 of the rotary latch 11 in the direction of arrow 44. The lock is now in its release position and the door, flap or trunk lid can be opened.
In Fig. 3 ist nun dargestellt, wie die motorische Öffnungs-/Zuziehhilfe in ihre Grundstellung zurückgefahren wird. Nach der Anlage des Nockens 37' an dem Sperrelement 25 der Klinke 21 (siehe Fig. 2) wird der Antriebsmotor 29 über eine Steuerung abgeschaltet und für einen bestimmten Zeitintervall in entgegengesetzer Laufrichtung wieder in Betrieb gesetzt. Hierdurch wird das auf der Achse a 33 angeordnete Zahnrad a 34 in Pfeilrichtung 46 in Bewegung gesetzt und zwar genau um den Bewegungsbetrag, bis der Nocken 37' wieder die aus Fig. 1 ersichtliche Grundstellung eingenommen hat. Auch das Antriebselement 38 und das Zahnrad b 35 auf der Achse b 36 werden in Pfeilrichtung 47 um genau den Betrag bewegt, bis sie sich wieder in der aus Fig. 1 ersichtlichen Grundstellung befinden. Die Klinke 21 wird dabei auf Grund der auf sie einwirkenden Federbelastung in Pfeilrichtung 45 wieder in Richtung auf die Drehfalle 11 bewegt, bis es zu einer Anlage des Abstützelementes 27 der Klinke 21 an der Kante 17 der Drehfalle 1 1 kommt.In Fig. 3 it is now shown how the motorized opening / closing aid is moved back into its basic position. After the cam 37 'has been applied to the locking element 25 of the pawl 21 (see FIG. 2), the drive motor 29 is switched off via a control and is put back into operation for a certain time interval in the opposite direction. As a result, the gear a 34 arranged on the axis a 33 is set in motion in the direction of the arrow 46, specifically by the amount of movement, until the cam 37 'has again assumed the basic position shown in FIG. The drive element 38 and the gearwheel b 35 on the axis b 36 are also moved in the arrow direction 47 by exactly the amount until they are again in the basic position shown in FIG. 1. The pawl 21 is due to the spring load acting on it in the direction of arrow 45 in again Moves towards the catch 11 until the support element 27 of the pawl 21 abuts against the edge 17 of the catch 11.
In Fig. 4 ist das Schloß durch ein manuelles Zuschlagen der Tür, Klappe od.dgl. in die Vorrastlage der Drehfalle 11 überführt worden. Das Schließteil 20 ist dabei in Pfeilrichtung 48 in die Aufnahme 16 der Drehfalle 1 1 eingedrückt, und dadurch die Drehfalle 1 1 in Pfeilrichtung 48' und entgegen der auf die sie wirkenden Federbelastung in Pfeilrichtung 49 verschwenkt worden. Das Abstützelement 27 der Klinke 21 ist dabei entlang der Kante 17 der Drehfalle 1 1 gelaufen, bis es in die Vorrast 15 der Drehfalle 11 eingefallen ist und dort nun als Rasthaken 24 ein Zurückschwenken der Drehfalle 11 in Richtung der Federbelastung 49 verhindert. Die Klinke 21 bleibt dabei unter ihrer Federbelastung 45 an die Drehfalle 1 1 angedrückt. Diese Vorrastlage wird von einem am Schloß befindlichen Sensor erkannt, der daraufhin den Antriebsmotor 29 als Zuziehhilfe in Betrieb setzt. Diese Bewegung wird über die Schnecke 31 auf das Schneckenrad 32 übertragen, welches in Pfeilrichtung 50 bewegt wird. Von dem Zahnrad a 34 wird diese Drehbewegung auf das Zahnrad b 35 übertragen, welches sich dann in Pfeilrichtung 51 dreht. Das mit dem Zahnrad b 35 auf der Achse b 36 befindliche Abtrieb selement 38 mit seinem Arm 39 und seinem Nocken 39' wird ebenfalls in Pfeilrichtung 51 verschwenkt, bis es gegen die Schulter 12 der Drehfalle 11 fährt (vergl. Fig. 5). Nachdem der Nocken 39' gegen die Schulter 12 an der Drehfalle 11 gefahren ist, wird die Drehfalle 1 1, wie aus Fig. 6 ersichtlich, weiter in Pfeilrichtung 52 verschwenkt, bis die Drehfalle 1 1 in eine Überhublage versetzt ist, in der die Hauptrast 14 mit einem Überhub gemäß Pfeil 53 über dem Rasthaken 24 steht. Die Nase, in der sich die Hauptrast 14 befindet, ist dabei an dem Rasthaken 24 verbeibewegt worden, wobei die Klinke 21 kurzfristig entgegen der Federbelastung gemäß Pfeil 45 von der Drehfalle 11 weggerückt worden ist.In Fig. 4, the lock or the like by manually slamming the door, flap. have been transferred to the latching position of the rotary latch 11. The locking part 20 is pressed in the direction of arrow 48 into the receptacle 16 of the rotary latch 11, and thereby the rotary latch 11 has been pivoted in the arrow direction 48 'and counter to the spring load acting on it in the arrow direction 49. The support element 27 of the pawl 21 has run along the edge 17 of the rotary latch 11 until it has fallen into the preliminary catch 15 of the rotary latch 11 and there, as latching hooks 24, prevents the rotary latch 11 from pivoting back in the direction of the spring load 49. The pawl 21 remains pressed under its spring load 45 on the rotary latch 11. This pre-locking position is recognized by a sensor located at the lock, which then starts the drive motor 29 as a closing aid. This movement is transmitted via the worm 31 to the worm wheel 32, which is moved in the direction of the arrow 50. This rotary motion is transmitted from gear a 34 to gear b 35, which then rotates in the direction of arrow 51. The with the gear b 35 on the axis b 36 output element 38 with its arm 39 and its cam 39 'is also pivoted in the direction of arrow 51 until it moves against the shoulder 12 of the rotary latch 11 (see. Fig. 5). After the cam 39 'has moved against the shoulder 12 on the rotary latch 11, the rotary latch 11, as shown in FIG. 6, is pivoted further in the direction of the arrow 52 until the rotary latch 11 is set in an overtravel position in which the main catch 14 stands with an overstroke according to arrow 53 above the locking hook 24. The nose in which the main catch 14 is located has been moved past the catch hook 24, the pawl 21 being moved away from the catch 11 for a short time against the spring load according to arrow 45.
In dieser Überhublage lösen Sensoren einen Motorstopp aus, dem eine Rückstellung der motorischen Zuzieh-/Öffungshilfe in den Pfeilrichtungen 55 und 54 folgt. Die Abtriebselemente 38 und 37 werden dabei ebenfalls in Pfeilrichtung 55 und 54 in die aus Fig. 1 ersichtliche Grundstellung zurückbewegt, wobei die Drehfalle 1 1 aus ihrer Überhublage in ihre Hauptrastlage, wie aus Fig. 1 ersichtlich, überführt wird.' In this overstroke position, sensors trigger an engine stop, which is followed by a reset of the motorized closing / opening aid in the direction of arrows 55 and 54. The output elements 38 and 37 are also moved back in the direction of the arrows 55 and 54 into the basic position shown in FIG. 1, the rotary latch 11 being transferred from its overstroke position to its main detent position, as can be seen in FIG. 1. '
Es bleibt nun noch zu bemerken, das die hier dargestellte Ausführungsform nur eine beispielhafte Verwirklichung der Erfindung darstellt. Diese ist jedoch nicht darauf beschränkt. So können z.B. die Zahnräder auch als Treibräder ausgeführt sein. B e z u i c h e n 1 i s t eIt remains to be noted that the embodiment shown here represents only an exemplary implementation of the invention. However, this is not limited to this. For example, the gears can also be designed as driving wheels. Reference 1
