Description

Die Erfindung betrifft eine Vorrichtung zum Verschließen einer mit einem Türschloß versehenen Fahrzeugtür, Motorhaube, Kofferraumdeckel, Heckklappe o.dgl., wobei die Vorrichtung ein auf einem Trägerteil angeordnetes bolzen- oder bügelförmiges Schließelement umfaßt, und wobei das Schließelement einerseits mit Hilfe einer einen Antriebsmotor mit nachgeschaltetem Getriebe enthaltenden Antriebseinrichtung gegen den Druck mindestens einer Feder von einer Ent- in eine Verriegelungsstellung bewegbar ist und andererseits in der Entriegelungsstellung durch eine dem Türschloß zugeordnete schwenkbare Gabelfalle umgreifbar ist, so daß das Schließelement bei seiner Bewegung in die Verriegelungsstellung über die Gabelfalle die Fahrzeugtür etc. in deren geschlossene Stellung zieht.The invention relates to a device for closing a vehicle door, hood provided with a door lock, Luggage compartment lid, tailgate or the like, the device a bolt or bow-shaped arranged on a carrier part Closing element comprises, and wherein the closing element on the one hand with the help of a drive motor with a downstream Gearbox containing drive device against the pressure of at least one spring from one to the other Locking position is movable and on the other hand in the Unlocked position by one assigned to the door lock pivotable fork latch can be gripped so that the closing element when moving into the locked position the fork latch the vehicle door etc. in its closed Position.

Eine derartige Schließ- bzw. Zuziehhilfe für Fahrzeugtüren etc. ist beispielsweise aus der DE 197 37 996 A1 bekannt. Bei dieser bekannten Vorrichtung wird das Trägerteil des Schließelementes mittels einer Antriebseinrichtung verschoben, die einen Exzenter mit einem Steuernocken antreibt, welcher direkt auf die Randbereiche einer Ausnehmung des Trägerteiles einwirkt. Um sicherzustellen, daß bei einem manuellen Schließen der Fahrzeugtür keine Behinderung durch den Exzenter erfolgt, weist die Ausnehmung in Bewegungsrichtung des Trägerteiles ein lichtes Maß auf, das dem Außendurchmesser der Bewegungsbahn des Exzenters entspricht.Such a closing or closing aid for vehicle doors etc. is known for example from DE 197 37 996 A1. at this known device becomes the carrier part of the closing element shifted by means of a drive device which drives an eccentric with a control cam, which directly on the edge areas of a recess of the carrier part acts. To ensure that with a manual Closing the vehicle door no obstruction by the eccentric takes place, the recess points in the direction of movement Carrier part on a clear measure that the outer diameter corresponds to the movement path of the eccentric.

Nachteilig bei dieser bekannten Vorrichtung ist unter anderem, daß das Trägerteil des Schließelementes relativ aufwendig aufgebaut ist, weil es einerseits eine der Bewegungsbahn des Exzenters entsprechend breite Ausnehmung aufweist und andererseits eine ausreichende Stabilität besitzen muß. Nachteilig ist ferner, daß zum Verschließen der Fahrzeugtür bei Ausfall der Antriebseinrichtung eine separate Handeinstelleinrichtung vorgesehen ist, mittels welcher das Trägerteil des Schließelementes manuell in die Verriegelungsstellung verschoben und in dieser Stellung dann anschließend fixiert werden muß.A disadvantage of this known device is, among other things, that the carrier part of the closing element is relatively complex is built up because it is one of the trajectory of the eccentric has a correspondingly wide recess and on the other hand must have sufficient stability. Another disadvantage is that to close the vehicle door if the drive device fails, a separate manual setting device is provided, by means of which the carrier part the locking element manually in the locking position moved and then in this position must be fixed.

Aus der DE 196 16 655 A1 ist ebenfalls eine als Schließhilfe für Fahrzeugtüren dienende gattungsgemäße Vorrichtung bekannt, bei welcher die Verschiebung des das Schließelement aufnehmenden Trägerteiles durch eine direkt auf das Trägerteil wirkende Antriebsvorrichtung erfolgt. Dabei drückt ein von der Antriebsvorrichtung gedrehter Nocken so lange gegen einen an dem Trägerteil angeordneten Mitnehmer, bis das Trägerteil durch einen schwenkbaren federbelasteten Fanghebel in seiner Verriegelungsstellung fixiert wird. Anschließend wird der Nocken dann noch so lange weitergedreht, bis er nicht mehr im Eingriff mit dem Mitnehmer ist.From DE 196 16 655 A1 is also a locking aid generic device known for vehicle doors, in which the displacement of the closing element receiving carrier part by a directly on the carrier part acting drive device takes place. It presses in against the cam rotated by the drive device a driver arranged on the carrier part until the carrier part by a swiveling spring-loaded catch lever in its locking position is fixed. Then will the cam then continued to rotate until it did not is more engaged with the driver.

Um das Trägerteil wieder von der Ver- in die Entriegelungsstellung zu verschieben, wird der Fanghebel entweder mittels eines separaten Antriebes oder über ein mit der Antriebseinrichtung verbundenes Getriebe aus der Fixierstellung herausgeschwenkt. Around the carrier part again from the locked to the unlocked position to move, the catch lever is either by means of of a separate drive or via one with the drive device connected gear swiveled out of the fixing position.

Zwar besitzt diese bekannte Vorrichtung gegenüber der DE 197 37 996 A1 unter anderem die Vorteile, daß eine Ausnehmung in dem Trägerteil des Schließelementes für einen Exzenter nicht erforderlich ist und daß zum Verschließen der Fahrzeugtür bei Ausfall der Antriebseinrichtung ein manuelles Verschieben des Trägerteiles in die Verriegelungsstellung entfallen kann, weil der Fanghebel diese Funktion mit übernimmt, doch ist bei der bekannten Vorrichtung eine relativ platzaufwendige Antriebseinrichtung erforderlich.This known device has compared to DE 197 37 996 A1, inter alia, the advantages that a recess in not the carrier part of the closing element for an eccentric is required and that to close the vehicle door Failure of the drive means a manual shift of the Carrier part can be omitted in the locking position, because the catch lever also takes on this function, but is at the known device a relatively space-consuming drive device required.

Aus der nicht vorveröffentlichten deutschen Patentanmeldung 199 10 031.4 ist schließlich eine gattungsgemäße Vorrichtung bekannt, bei der zwischen dem von der Antriebseinrichtung betätigten Steuernocken und dem Trägerteil des Schließelementes ein laschenförmiges Koppelelement vorgesehen ist, welches eine erste Ausnehmung enthält, in die der Steuernocken formschlüssig eingreift und welches eine als Langloch ausgebildete zweite Ausnehmung enthält, in die eine mit dem Trägerteil des Schließelementes verbundene zapfenförmige Verlängerung eingreift. Die Länge des Langloches ist dabei derart gewählt, daß das in der Entriegelungsstellung befindliche Schließelement manuell ohne Behinderung durch den Steuernocken in seine Verriegelungsstellung verschiebbar ist.From the unpublished German patent application Finally, 199 10 031.4 is a generic device known in the between that of the drive device actuated control cam and the support part of the closing element a tab-shaped coupling element is provided, which contains a first recess into which the control cam has a positive fit engages and which one designed as an elongated hole contains second recess, in one with the carrier part of the closing element connected pin-shaped extension intervenes. The length of the elongated hole is chosen such that that the locking element is in the unlocked position manually without hindrance by the control cam in its Locking position is displaceable.

Auch diese Vorrichtung ist relativ platzaufwendig, da das gesamte Trägerteil des Schließelementes verschiebbar gelagert sein muß.This device is also relatively space-consuming since the entire Carrier part of the closing element slidably mounted have to be.

Ausgehend von der 199 10 031.4 liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs erwähnten Art anzugeben, die einfach und platzsparend ausgestaltet ist.The present invention is based on the 199 10 031.4 the task of a device of the type mentioned Specify type that is simple and space-saving is.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of characterizing part of claim 1 solved. More, especially disclose advantageous embodiments of the invention the subclaims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, anstatt eines verschiebbaren Trägerteiles ein verschwenkbares Trägerteil zu verwenden. Als vorteilhaft hat sich als Trägerteil ein z.B. zweiarmiger Umlenkhebel erwiesen, an dessen ersten Hebelarm über die zapfenförmige Verlängerung das Koppelelement und an dessen zweiten Hebelarm das Schließelement angeordnet ist.The invention is essentially based on the thought rather than a slidable carrier part a pivotable Carrier part to use. Has proven to be advantageous as a carrier part a e.g. two-armed bell crank proven first lever arm over the pin-shaped extension the coupling element and on its second lever arm the closing element is arranged.

Abgesehen davon, daß ein verschwenkbares Trägerteil einfach zu fertigen und platzsparend an dem Fahrzeug zu montieren ist, weist es den Vorteil auf, daß durch entsprechende Zuordnung von Koppel- und Schließelement auf einfache Weise eine Anpassung der erfindungsgemäßen Vorrichtung an die vorgegebenen Raumverhältnisse vorgenommen werden kann. Insbesondere hat es sich als vorteilhaft erwiesen, das Koppelelement und das Schließelement derart an dem Trägerteil anzuordnen, daß sich bei einer axialen Verschiebung des Koppelelementes das Schließelement in einer zur Bewegungsrichtung des Koppelelementes etwa senkrechten Richtung bewegt.Apart from the fact that a pivotable support part is simple to manufacture and to save space on the vehicle it has the advantage that by appropriate assignment coupling and closing element in a simple way an adaptation of the device according to the invention to the given space conditions can be made. In particular the coupling element has proven to be advantageous and the closing element in this way on the carrier part to arrange that with an axial displacement of the Coupling element, the closing element in a direction of movement of the coupling element moves approximately in the vertical direction.

Als besonders vorteilhaft hat es sich ferner erwiesen, wenn zur Fixierung des Schließelementes in seiner Verriegelungsstellung ein federbeaufschlagter Fanghebel vorgesehen ist, welcher in dieser Stellung den ersten Hebelarm des Trägerteiles fixiert. Dadurch wird erreicht, daß bei einem manuellen Zuschlagen der Fahrzeugtür -unabhängig davon, ob die Antriebseinrichtung ausgefallen ist oder nicht- diese sicher verschlossen wird. It has also proven to be particularly advantageous if to fix the locking element in its locking position a spring-loaded catch lever is provided, which in this position the first lever arm of the support part fixed. This ensures that with a manual Slamming the vehicle door regardless of whether the drive device has failed or is not safe is closed.

Um den Fanghebel auf einfache Weise in seine Ausgangslage zurückzuschwenken, wenn das Schließelement von der Ver- in die Entriegelungsstellung verschoben werden soll, hat es sich als zweckmäßig erwiesen, wenn an dem Koppelelement ein Steuerhebel angeordnet ist, der bei Drehung des Nockenrades von der Ver- in die Entriegelungsstellung den Fanghebel in seine Freigabestellung verschwenkt.In order to easily swing the catch lever back into its original position, when the closing element from the ver to the Unlocked position to be moved, it has turned out to be Proven useful when a control lever on the coupling element is arranged, the rotation of the cam wheel of the In the unlocking position the catch lever in his Release position pivoted.

Das Koppelelement 9 besitzt ferner ein sich in axialer Richtung erstreckendes Langloch 10, in welches ein mit dem ersten Hebelarm 11 eines Umlenkhebels 12 verbundener Zapfen 13 eingreift. An dem zweiten Hebelarm 14 des Umlenkhebels 12 ist ein Schließbolzen 15 befestigt, welcher von einer gestrichelt dargestellten, dem Türschloß zugeordneten Gabelfalle 16 umgriffen ist. Der Umlenkhebel 12 wird durch eine Drehfeder 17 in seiner in Fig.1 und 2 dargestellten Ausgangslage (Entriegelungsstellung) gehalten, wobei der erste Hebelarm 11 an einem mit 18 bezeichneten Anschlag anliegt und der Zapfen 13 sich an dem einen Ende 19 des Langloches 10 abstützt.The coupling element 9 also has an axially extending slot 10, in which one with the first Lever arm 11 of a bell crank 12 engages connected pin 13. On the second lever arm 14 of the bell crank 12 a locking bolt 15 attached, which is dashed by a shown, the fork lock 16 associated with the door lock is. The bell crank 12 is by a torsion spring 17th in its initial position shown in FIGS. 1 and 2 (unlocked position) held, the first lever arm 11 on abuts a stop designated 18 and the pin 13 is supported on one end 19 of the elongated hole 10.

Die Vorrichtung 1 umfaßt ferner einen schwenkbar angeordneten Fanghebel 20, der durch eine Druckfeder 21 gegen den ersten Hebelarm 11 des Umlenkhebels 12 gedrückt wird. Außerdem ist an dem Koppelelement 9 ein Steuerhebel 22 verschwenkbar angeordnet, dessen Funktion nachfolgend noch näher beschrieben wird.The device 1 further comprises a pivotally arranged Catch lever 20 by a compression spring 21 against the first Lever arm 11 of the bell crank 12 is pressed. Besides, is a control lever 22 is pivotably arranged on the coupling element 9, its function is described in more detail below becomes.

Die Fig.1 und 2 zeigen den Schließbolzen 15 in der Entriegelungsstellung. Dabei sei die Heckklappe des nicht dargestellten Fahrzeuges an dessen heckseitiger Karosserie angelehnt und das Türschloß möge sich in seiner Vorraststellung befinden, bei der die Gabelfalle 16 den Schließbolzen 15 umfaßt und durch eine nicht dargestellte Sperrklinke gesichert ist. Gleichzeitig mit der Sicherung der Gabelfalle 16 durch die Sperrklinke wird über einen z.B. im Türschloß befindlichen Mikroschalter der Antriebsmotor 3 (Fig.2) der erfindungsgemäßen Vorrichtung 1 aktiviert und das Nockenrad 5 dreht sich aus der in Fig.1 dargestellten Stellung entgegen dem Uhrzeigersinn (Fig.3-8).1 and 2 show the locking bolt 15 in the unlocked position. The tailgate of the not shown Vehicle leaned against the rear body and the door lock may be in its pre-locked position, in which the fork latch 16 includes the locking bolt 15 and is secured by a pawl, not shown. Simultaneously with the securing of the fork latch 16 by the Pawl is e.g. located in the door lock Microswitch of the drive motor 3 (Fig.2) of the invention Device 1 activated and the cam wheel 5 rotates from the position shown in Figure 1 counterclockwise (Fig.3-8).

Dabei drückt der Steuernocken 7 gegen das stangenförmige Koppelelement 9 und verschiebt dieses in Richtung seiner Längsachse 23. Das als Anschlag wirkende Ende 19 des Langloches 10 drückt gegen den Zapfen 13 und verschwenkt dadurch den Umlenkhebel 12 gegen den Druck der Drehfeder 17 in Richtung des mit 24 bezeichneten Pfeiles (Fig.1). Hierbei nimmt der Schließbolzen 15 die Gabelfalle 16 des Türschlosses mit, so daß die Heckklappe des entsprechenden Fahrzeuges definiert gegen die zwischen Heckklappe und Karosserie befindliche (nicht dargestellte) Gummidichtung gezogen wird.The control cam 7 presses against the rod-shaped coupling element 9 and moves it in the direction of its longitudinal axis 23. The end 19 of the elongated hole 10 acting as a stop presses against the pin 13 and thereby pivots the bell crank 12 against the pressure of the torsion spring 17 in the direction of with 24 designated arrow (Fig.1). Here, the Lock bolt 15 with the fork latch 16 of the door lock, so that defines the tailgate of the corresponding vehicle against the one between the tailgate and the body Rubber seal (not shown) is pulled.

Sobald die Heckklappe geschlossen und damit die Verriegelungsstellung des Schließbolzens 15 erreicht ist (Fig.7 und 8), rastet der als Sperrnase 25 ausgebildete Endbereich des Fanghebels 20 in eine Rastnut 26 des ersten Hebelarmes 11 des Umlenkhebels 12 ein (Fixierstellung des Fanghebels) und der Antriebsmotor 3 (Fig.2) wird über einen nicht dargestellten Mikroschalter wieder abgeschaltet.As soon as the tailgate closed and thus the locking position of the locking bolt 15 is reached (Fig.7 and 8), the end portion of the Catch lever 20 in a locking groove 26 of the first lever arm 11 of the Deflection lever 12 a (fixing position of the catch lever) and Drive motor 3 (Fig.2) is a not shown Microswitch switched off again.

Zur Entriegelung des Schließbolzens 15 wird beispielsweise durch Betätigung eines Griffes oder des Schließzylinders der Heckklappe der Antriebsmotor 3 wiederum aktiviert und dreht das Nockenrad 5 weiter entgegen dem Uhrzeigersinn (Fig.9-12). Dabei verharrt der Schließbolzen 15 zunächst in seiner Verriegelungsstellung, bis der Steuerhebel 22 den Fanghebel 20 erreicht und den Umlenkhebel 12 freigibt (Fig.9 und 10).To unlock the locking bolt 15, for example by operating a handle or the locking cylinder of the The tailgate of the drive motor 3 in turn is activated and rotates the cam wheel 5 further counterclockwise (Fig. 9-12). The locking bolt 15 initially remains in its locking position, until control lever 22 catch lever 20 reached and releases the bell crank 12 (Fig. 9 and 10).

Anschließend wird der Umlenkhebel 12 zurückverschwenkt, bis der Zapfen 13 gegen das als Anschlag wirkende Ende 19 des Langloches 10 des Koppelelementes 9 stößt (Fig.11 und 12) und dann durch das Koppelelement 9 zwangsgeführt wird, bis die Entriegelungsstellung des Schließbolzens (Fig.1 und 2) erreicht ist und der Antriebsmotor 3 automatisch ausgeschaltet wird.Then the bell crank 12 is pivoted back until the pin 13 against the end acting as a stop 19 of the Elongated hole 10 of the coupling element 9 abuts (Fig. 11 and 12) and is then positively guided by the coupling element 9 until the Unlocking position of the locking bolt (Fig. 1 and 2) reached is and the drive motor 3 is automatically switched off becomes.

For example the pivoting support part also moving cause a striker. A corresponding embodiment give the Fig.13 and 14 again, Fig.13 with the 29 designated striker in its unlocked position and Fig. 14 the striker in its locked position shows.

Zum Verschieben des Schließbügels 29 ist sein erster Schenkel 30 an einem verschwenkbaren scheibenförmigen Trägerteil 31 angeordnet, welches im wesentlichen dem in den Fig.1-12 mit 12 bezeichneten Umlenkhebel entspricht. Der zweite Schenkel 32 des Schließbügels 29 ist hingegen an einer zusätzlichen, ebenfalls schwenkbaren Flanschplatte 33 befestigt. Die Wirkungsweise dieser Vorrichtung entspricht im wesentlichen der im Zusammenhang mit den Fig.1 bis 12 beschriebenen erfindungsgemäßen Vorrichtung. To move the striker 29 is its first leg 30 on a pivotable disk-shaped carrier part 31 arranged, which is essentially the same as that in FIGS 12 designated lever corresponds. The second leg 32 of the striker 29, however, is on an additional, also pivoted flange plate 33 attached. The mode of action this device corresponds essentially to the 1 to 12 described in connection with the invention Contraption.
