Description

Die Erfindung bezieht sich auf ein motorisches Stellele­ment für eine Zentralverriegelungsanlage, welches eine zum Betätigen eines Türschlosses vorgesehene, mit einer Knopfstange gekoppelte und zwischen zwei Endstellungen mittels eines Motors bewegbare Schloßstange und eine Sperreinrichtung zur Diebstahlsicherung hat. Solche Stellelemente sind in Zentralverriegelungsanlagen heuti­ger Kraftfahrzeuge eingebaut und allgemein bekannt.The invention relates to a motorized actuating element for a central locking system, which has a lock rod provided for actuating a door lock, coupled with a button rod and movable between two end positions by means of a motor, and a locking device for theft protection. Such actuators are installed in central locking systems of today's motor vehicles and are generally known.

Bei den bekannten Stellelementen ist die Knopfstange fest mit der Schloßstange verbunden. In der Diebstahl­sicherungsstellung wird die Schloßstange unverschiebbar blockiert, damit ein Einbrecher nach einem gewaltsamen Öffnen eines Fensters die Schloßstange nicht durch Ziehen am Ende der zugehörigen Knopfstange hochbewegen und so das Schloß entsichern und danach die Tür öffnen kann. Die Diebstahlsicherung ist nur mit dem Schlüssel aufzuheben, indem ein elektrischer Kontakt im Schloß betätigt wird und dadurch die Sperre motorisch gelöst wird.In the known actuators, the button bar is firmly connected to the lock bar. In the anti-theft position, the lock bar is immovably blocked so that a burglar cannot pull the lock bar up by pulling the end of the associated button bar after a window has been opened violently, thus unlocking the lock and then opening the door. The anti-theft device can only be removed with the key by actuating an electrical contact in the lock and thereby releasing the lock by a motor.

Nachteilig bei den bekannten Zentralverriegelungsanlagen ist es, daß bei einem Ausfall des Bordnetzes die Dieb­stahlsicherung nicht mehr entsichert werden kann. Des­halb verzichtet man an der Fahrertür auf eine solche Diebstahlsicherung und sieht stattdessen dort eine mecha­nische, mittels des Schlüssels zu betätigende Diebstahl­sicherung vor. Dadurch kann bei einem Ausfall des Bord­netzes wenigstens die Fahrertür noch geöffnet werden. Nachteilig bei einer solchen Zentralverriegelungsanlage ist es natürlich, daß bei ihr die Diebstahlsicherung aller Türen nur mittels des Schlüssels an der Fahrertür erfolgen kann.A disadvantage of the known central locking systems is that the anti-theft device can no longer be unlocked if the vehicle electrical system fails. For this reason, the driver's door is not equipped with such an anti-theft device and instead there is a mechanical anti-theft device that can be operated using the key. As a result, at least the driver's door can still be opened in the event of a failure of the vehicle electrical system. A disadvantage of such a central locking system is, of course, that the anti-theft protection of all doors can only be carried out by means of the key on the driver's door.

Der Erfindung liegt die Aufgabe zugrunde, ein motori­sches Stellelement der eingangs genannten Art derart zu gestalten, daß sich auch ohne Energieversorgung über das Bordnetz alle Türschlösser öffnen lassen, wenn ihre Dieb­stahlsicherung eingeschaltet ist und welches bei Vorhan­densein von Bordspannung von allen einen Schließzylinder aufweisenden Türen betätigbar ist.The invention has for its object to design a motorized actuator of the type mentioned in such a way that even without energy supply via the vehicle electrical system, all door locks can be opened if their anti-theft device is switched on and which can be actuated by all doors having a lock cylinder in the presence of on-board voltage .

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Diebstahlsicherung durch einen die Verschiebbarkeit der Schloßstange begrenzenden, motorisch angetriebenen, durch Federkraft in Entriegelungsstellung gehaltenen Riegel gebildet und zur Betätigung des Motors des Rie­gels in Verriegelungsrichtung ein mit seinem Taster gegen die Schloßstange anliegender Endlagenschalter vorgesehen ist und daß in Schließstellung der Schloß­stange unterhalb des Endlagenschalters in der Schloß­stange zum Schalten des Endlagenschalters ein Steuerbe­reich vorgesehen ist.This object is achieved in that the anti-theft device is formed by a motor-driven bolt which limits the displaceability of the lock rod and is held in the unlocking position by spring force, and for the actuation of the motor of the bolt in the locking direction there is provided a limit switch which rests against the lock rod and that in the closed position of the lock rod below the limit switch, a control area is provided in the lock rod for switching the limit switch.

Bei einer solchen, erfindungsgemäßen Diebstahlsicherung handelt es sich um eine Bedarfsdiebstahlsicherung. Die Schloßstange wird nur vorübergehend verriegelt, wenn an ihr gezogen und dadurch der Endlagenschalter betätigt wird. Da der Motor den Riegel in Verriegelungsrichtung bewegt und bei Ausfall des Bordnetzes der Riegel durch Federkraft in Entriegelungsstellung vorgespannt ist, kann es bei Ausfall des Bordnetzes nicht dazu kommen, daß eine diebstahlgesicherte Tür nicht mit dem Schlüssel zu öffnen ist. Durch das erfindungsgemäße Stellelement wird somit eine Bedarfsdiebstahlsicherung geschaffen, die die Schloßstange nur sichert, wenn sie bei einge­schalteter Diebstahlsicherung mittels des mit ihr starr verbundenen Sicherungsknopfes geringfügig hochgezogen wird, ohne daß die Offenstellung erreicht wird. Mit dem erfindungsgemäßen Stellelement ist eine Mehrtürbetäti­gung möglich. Es ist nicht mehr erforderlich, die Fahrer­tür mit einer mechanisch vom Schlüssel betätigbaren Dieb­stahlsicherung zu versehen.Such an anti-theft device according to the invention is an anti-theft device. The lock bar is only temporarily locked when it is pulled and the limit switch is thereby actuated. Since the motor moves the bolt in the locking direction and in the event of a failure of the vehicle electrical system, the bolt is pretensioned in the unlocking position by spring force, if the vehicle electrical system fails, it cannot happen that an anti-theft door cannot be opened with the key. The actuating element according to the invention thus creates a theft protection requirement, which only secures the lock bar if it is pulled up slightly by means of the security button rigidly connected to it while the anti-theft device is switched on, without the open position being reached. Multi-door actuation is possible with the actuating element according to the invention. It is no longer necessary to provide the driver's door with an anti-theft device that can be mechanically operated by the key.

Besonders einfach läßt sich der Endlagenschalter durch geringfügiges Verschieben der Schloßstange betätigen, wenn der Steuerbereich durch eine Steuernut in der Schloßstange gebildet ist.The limit switch can be actuated particularly easily by slightly shifting the lock rod if the control area is formed by a control groove in the lock rod.

Der Motor zum Bewege des Riegels ist besonders einfach und damit kostengünstig, wenn es sich bei ihm um eine Magnetspule handelt.The motor for moving the bolt is particularly simple and therefore inexpensive if it is a solenoid.

Auch die elektrische Beschaltung des Stellelementes ist sehr einfach, wenn gemäß einer anderen Ausgestaltung der Erfindung der Riegel durch eine Feder in der entsperrten Stellung vorgespannt und der Endlagenschalter zum Schließen eines Versorgungsstromkreises der Magnetspule ausgebildet ist.The electrical connection of the actuating element is also very simple if, according to another embodiment of the invention, the bolt is pretensioned in the unlocked position by a spring and the limit switch is designed to close a supply circuit of the magnetic coil.

Eine ganz besonders vorteilhafte Ausgestaltung der Erfin­dung besteht darin, daß zum Verrasten des Riegels mit der Schloßstange auf der Schloßstange ein um eine an seiner unteren Seite vorgesehene Achse innerhalb eines ein Verrasten mit dem Riegel ermöglichenden Bereichs schwenkbarer, mittels einer Feder in einer Mittelstel­lung gehaltener Klapphaken vorgesehen ist. Ein solcher Klapphaken liegt im diebstahlgesicherten Zustand beim Hochziehen der Schloßstange mit Vorspannung gegen den Riegel an. Das hat zur Folge, daß nach einem Loslassen des Sicherungsknopfes dieser zusammen mit der Schloß­stange durch die Federkraft des Riegels wieder zurück in seine Ausgangsstellung, die Sicherungsstellung, gelangt und der Riegel dann wieder zurückfahren kann. Dadurch wird nur während des Hochziehens kurzfristig Strom zum Betätigen und Halten des Riegels in Verriegelungsstel­lung benötigt. Zum Aufrechterhalten der Bedarfsdiebstahl­sicherung ist keine elektrische Energie erforderlich.A very particularly advantageous embodiment of the invention consists in that for latching the bolt with the lock rod on the lock rod, a folding hook is provided which is pivotable by means of a spring in a central position and which is pivotable about an axis provided on its lower side within a region which permits latching with the bolt is. Such a folding hook is in the anti-theft state when pulling up the lock rod with pretension against the bolt. The result of this is that, after the safety button has been released, the latter, together with the lock rod, returns to its starting position, the safety position, by the spring force of the bolt and the bolt can then move back again. As a result, current is only needed for a short time during the pull-up to operate and hold the bolt in the locking position. No electrical energy is required to maintain the anti-theft device.

Das Stellelement eignet sich sehr gut für pneumatisch arbeitende Zentralverriegelungsanlagen. Hierbei ist vorteilhafterweise die Schloßstange unmittelbar mit einer Membran eines pneumatischen Stellmotors verbunden.The control element is very well suited for pneumatic central locking systems. Here, the lock rod is advantageously connected directly to a membrane of a pneumatic servomotor.

Das erfindungsgemäße Stellelement kann jedoch auch elek­tromotorisch arbeiten, indem die Schloßstange mittels einer Spindelmutter einer von einem Elektromotor antreib­baren Gewindespindel angetrieben ist.However, the actuating element according to the invention can also work by an electric motor, in that the lock rod is driven by means of a spindle nut of a threaded spindle which can be driven by an electric motor.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips sind zwei davon in der Zeichnung dargestellt und werden nachfol­gend beschrieben. Die Zeichnung zeigt in

  • Fig. 1 einen Längsschnitt durch ein pneumatisches Stellelement in Offenstellung,
  • Fig. 2 einen Längsschnitt durch das Stellelement nach Figur 1 in Schließstellung,
  • Fig. 3 einen Längsschnitt durch das Stellelement in diebstahlgesicherter Stellung,
  • Fig. 4 einen Längsschnitt durch ein elektromoto­risches Stellelement in diebstahlgesicherter Stellung,
  • Fig. 5 einen Längsschnitt durch das Stellelement nach Figur 4 in Offenstellung des Tür­schlosses.
The invention allows numerous embodiments. To further clarify its basic principle, two of them are shown in the drawing and are described below. The drawing shows in
  • 1 shows a longitudinal section through a pneumatic control element in the open position,
  • 2 shows a longitudinal section through the actuating element according to FIG. 1 in the closed position,
  • 3 shows a longitudinal section through the actuating element in the anti-theft position,
  • 4 shows a longitudinal section through an electromotive actuator in the anti-theft position,
  • 5 shows a longitudinal section through the actuating element according to FIG. 4 in the open position of the door lock.

Das in der Figur 1 dargestellte Stellelement hat in einem nicht dargestellten Gehäuse eine Schloßstange 1, welche unmittelbar mit einer Membran 2 eines teilweise dargestellten pneumatischen Motors 3 verbunden ist. Auf der Schloßstange 1 ist ein Klapphaken 4 um eine quer zur Schloßstange 1 verlaufende Achse 5 schwenkbar angeord­net, wobei die Achse 5 den Klapphaken 4 an seiner unte­ren Seite lagert. Schematisch angedeutet sind auf dem Klapphaken 4 zwei Anschläge 6, 7, zwischen denen eine blattförmige Feder 8 angeordnet ist. Schwenkt man den Klapphaken 4, so gelangen je nach Schwenkrichtung die Anschläge 6 oder 7 gegen die Feder 8 und verformen diese, so daß der Klapphaken 4 von der Feder 8 wieder zurückgestellt wird, wenn man ihn losläßt. In Spreizrich­tung ist die Schwenkbarkeit des Klapphakens 6 durch einen Anschlag 9 auf der Schloßstange 1 begrenzt.The actuator shown in Figure 1 has a lock rod 1 in a housing, not shown, which is connected directly to a membrane 2 of a pneumatic motor 3, partially shown. On the lock rod 1, a folding hook 4 is pivotally arranged about an axis 5 extending transversely to the lock rod 1, the axis 5 supporting the folding hook 4 on its lower side. Two stops 6, 7, between which a leaf-shaped spring 8 is arranged, are schematically indicated on the folding hook 4. If you swivel the folding hook 4, depending on the pivoting direction, the stops 6 or 7 move against the spring 8 and deform them so that the folding hook 4 is reset by the spring 8 when it is released. In the spreading direction, the pivotability of the folding hook 6 is limited by a stop 9 on the lock rod 1.

In der in Figur 1 gezeigten Offenstellung der Schloß­stange 1 befindet sich unterhalb des Klapphakens 4 ein Riegel 10, welcher die Form eines Bolzens hat und von einer Magnetspule 11 umschlossen ist. Eine Feder 12 spannt den Riegel 10 in die dargestellte, zurückgezogene Stellung vor. Wird die Magnetspule 11 erregt, so bewegt sich der Riegel 10 gegen die Kraft der Feder 12 in Rich­tung der Schloßstange 1.In the open position of the lock rod 1 shown in FIG. 1, there is a bolt 10 below the folding hook 4, which has the form of a bolt and is enclosed by a magnetic coil 11. A spring 12 biases the latch 10 in the illustrated, retracted position. If the magnet coil 11 is excited, the bolt 10 moves against the force of the spring 12 in the direction of the lock rod 1.

Zum Einschalten der Magnetspule 11 dient ein Endlagen­schalter 13, der mit einem Taster 14 gegen die Schloß­stange 1 anliegt und sich in der dargestellten Position in Offenstellung befindet. Angedeutet ist in der Figur 1 desweiteren ein mit einem Schlüssel betätigbarer Schließ­zylinder 15 mit einem Schalter 16 und die Schaltung der Magnetspule 11 mit dem Endlagenschalter 13.A limit switch 13 is used to switch on the solenoid coil 11, which bears against the lock rod 1 with a button 14 and is in the position shown in the open position. Also indicated in FIG. 1 is a lock cylinder 15, which can be actuated with a key, with a switch 16, and the switching of the solenoid 11 with the limit switch 13.

Oberhalb des Endlagenschalters 13 ist an der Schloß­stange 1 ein Steuerbereich in Form einer Steuernut 17 vorgesehen, in die der Taster 14 zu gelangen vermag, wenn sich die Schloßstange 1 entsprechend weit nach oben bewegt. Gelangt der Taster 14 in die Steuernut 17, dann schließt der Endlagenschalter 13.Above the limit switch 13, a control area in the form of a control groove 17 is provided on the lock rod 1, into which the button 14 is able to reach when the lock rod 1 moves correspondingly upwards. If the button 14 reaches the control groove 17, the limit switch 13 closes.

Die Figur 2 zeigt das Stellelement in Schließstellung. In ihr befinden sich der Klapphaken 4 unmittelbar unter­halb des Riegels 10 und die Steuernut 17 unmittelbar unterhalb des Tasters 14 des Endlagenschalters 13. Die Magnetspule 11 ist jedoch nicht erregt, so daß der Riegel 10 genau wie in Figur 1 eingefahren ist.Figure 2 shows the actuator in the closed position. In it, the folding hook 4 is located immediately below the bolt 10 and the control groove 17 immediately below the button 14 of the limit switch 13. The solenoid 11 is not energized, however, so that the bolt 10 is retracted exactly as in FIG.

Wird nun an dem mit der Schloßstange 1 verbundenen Sicherungsknopf gezogen, dann gelangt die Steuernut 17 vor den Taster 14, was in der Figur 3 gezeigt ist. Der Endlagenschalter 13 schließt dadurch, so daß die Magnet­spule 11 erregt wird und sich der Riegel 10 gegen die Kraft der Feder 12 zur Schloßstange 1 hin bewegt. Ein weiteres Hochziehen der Schloßstange ist nur noch im geringfügigen, durch die Verschwenkbarkeit des Klapp­hakens 4 zugelassenen Bereich möglich, so daß ein Ent­riegeln der Tür ausgeschlossen ist. Läßt man den Siche­rungsknopf wieder los, so bewegt sich die Schloßstange 1 zurück in die in Figur 2 gezeigte Stellung, in der der Riegel 10 wieder zurückgezogen ist.If the safety button connected to the lock rod 1 is now pulled, the control groove 17 arrives in front of the button 14, which is shown in FIG. 3. The limit switch 13 closes, so that the solenoid 11 is energized and the bolt 10 moves against the force of the spring 12 to the lock rod 1. A Further pulling up the lock bar is only possible in the slight range permitted by the pivoting of the folding hook 4, so that unlocking the door is impossible. If you let go of the safety button again, the lock rod 1 moves back into the position shown in FIG. 2, in which the bolt 10 is withdrawn again.

Die Figuren 4 und 5 zeigen, daß das erfindungsgemäße Prinzip auch bei einem elektromotorischen Stellelement anwendbar ist. Die Schloßstange 1 hat bei dieser Ausfüh­rungsform ein Kuppelstück 18, welches zusammen mit der Schloßstange 1 mittels einer Spindelmutter 19 angehoben oder abgesenkt werden kann. Die Schloßmutter 19 ist auf eine Gewindespindel 20 geschraubt, die ihrerseits über ein Getriebe 21 und einen Elektromotor 22 antreibbar ist.FIGS. 4 and 5 show that the principle according to the invention can also be used with an electromotive adjusting element. The lock rod 1 in this embodiment has a coupling piece 18 which can be raised or lowered together with the lock rod 1 by means of a spindle nut 19. The lock nut 19 is screwed onto a threaded spindle 20, which in turn can be driven via a gear 21 and an electric motor 22.

Der übrige Aufbau des Stellelementes nach den Figuren 4 und 5 entspricht dem des zuvor beschriebenen Stellele­mentes. In der in Figur 4 gezeigten diebstahlgesicherten Stellung wurde die Schloßstange 1 durch Ziehen am Siche­rungsknopf aus der Schließstellung geringfügig nach oben gezogen. Dadurch gelangte der Taster 14 in die Steuernut 17, welche bei dieser Ausführungsform im Kuppelstück 18 vorgesehen ist, so daß der Endlagenschalter 13 schaltete und die Magnetspule 11 bestromt wird. Der Riegel hat sich deshalb vor den Klapphaken 4 geschoben, so daß die Schloßstange 1 nicht weiter nach oben bis in Offenstel­lung gezogen werden kann.The remaining structure of the control element according to Figures 4 and 5 corresponds to that of the previously described control element. In the anti-theft position shown in FIG. 4, the lock rod 1 was pulled up slightly from the closed position by pulling the safety button. As a result, the button 14 came into the control groove 17, which is provided in the coupling piece 18 in this embodiment, so that the limit switch 13 switched and the solenoid 11 is energized. The bolt has therefore been pushed in front of the folding hook 4, so that the lock rod 1 cannot be pulled further up to the open position.

Wenn mit dem Schlüssel ein Türschloß auf "auf" geschlos­sen ist, dann ist die Stromverbindung zum Endlagenschal­ter 13 am Türschloß unterbrochen. Bei einer Aufwärtsbe­wegung der Schloßstange 1 wird zwar auch der Endlagen­schalter 13 kurzfristig geschlossen, jedoch hat das keine Wirkung, da keine Spannung ansteht. Die Schloß­ stange 1 kann sich deshalb mit dem Klapphaken 4 am zurückgezogenen Riegel 10 vorbei in die in Figur 5 ge­zeigte Offenstellung bewegen.If a door lock is closed with the key "open", then the power connection to the limit switch 13 on the door lock is interrupted. When the lock rod 1 moves upward, the limit switch 13 is also closed for a short time, but this has no effect since there is no voltage. The castle rod 1 can therefore move past the retracted latch 10 with the folding hook 4 into the open position shown in FIG. 5.
