Description

Die Erfindung bezieht sich auf eine Einrichtung zur Verstellung des Verriegelungshebels eines Türschlosses aus einer öffnungs- in eine Verriegelungsstellung und umgekehrt, wobei das Türschloß in der Verriegelungsstellung mit dem Außentürgriff nicht, mit dem Innentürgriff jedoch zu öffnen ist, enthaltend ein fernbedienbares Stellelement und einen von Hand zu betätigenden Türknopf, wobei das Stellelement über eine erste Betätigungsstange und der Türknopf über eine zweite Betätigungsstange mit dem Verriegelungshebel gekoppelt sind.The invention relates to a device for adjusting the locking lever of a door lock from an open to a locking position and vice versa, the door lock in the locked position not being able to be opened with the outer door handle, but with the inner door handle, containing a remote-controlled control element and one by hand door knob to be actuated, the actuating element being coupled to the locking lever via a first actuating rod and the door knob being coupled via a second actuating rod.

In heutigen Kraftfahrzeugen eingebaute Zentralverriegelungsanlagen haben pro Schloß zwei an verschiedenen Stellen eingebaute, meist pneumatisch arbeitende Stellelemente, von denen eines zur Betätigung der Türverriegelung und das andere zur zusätzlichen Diebstahlsicherung dient. Diese Anordnung erfordert für jedes Stellelement eine eigene Druckmittelleitung und entsprechende Drucksteuereinrichtungen an verschiedenen Stellen. Dadurch wird eine solche Zentralverriegelungsanlage aufwendig und störanfällig.In today's motor vehicles, central locking systems have two locks installed at different points, mostly pneumatically operating, one of which is used to actuate the door lock and the other to provide additional theft protection. This arrangement requires a separate pressure medium line and corresponding pressure control devices at different points for each control element. Such a central locking system is complex and prone to failure.

Wenn man die beiden pneumatischen Stellelemente in ein gemeinsames Gehäuse integriert und über eine einzige, gemeinsame Druckmittelleitung betätigen will, dann muß man eine Rangfolgesteuerung vorsehen, damit beim Verschließen einer Tür immer zunächst die Verriegelung und danach erst die Diebstahlsicherung und beim öffnen in umgekehrter Reihenfolge zunächst die Diebstahlsicherung und dann die Verriegelung betätigt werden.If you want to integrate the two pneumatic control elements in a common housing and operate them via a single, common pressure medium line, then you have to provide a priority control so that when a door is closed, the lock is activated first and then the anti-theft device and when the door is opened in reverse order, the anti-theft device and then the lock are activated.

Der Erfindung liegt die Aufgabe zugrunde, eine Zentralverriegelungsanlage der eingangs genannten Art so auszubilden, daß mit möglichst einfachen Mitteln beim Absperren eines Fahrzeugs zunächst verriegelt und dann diebstahlgesichert und beim öffnen genau umgekehrt zunächst diebstahlentsichert und dann entriegelt wird.The invention has for its object to provide a central locking system of the type mentioned so that with simple means when locking a vehicle first locked and then theft-proof and when opened the other way around theft-unlocked and then unlocked.

Diese Aufgabe wird bei der eingangs genannten Einrichtung erfindungsgemäß dadurch gelöst, daß

  • der Verriegelungshebel in Schließrichtung über die Schließstellung hinaus bis in eine Diebstahlsicherungsstellung verstellbar ist, in der das Türschloß ausschließlich mit dem Türschlüssel zu öffnen ist.
  • ein Sicherungsstift vorgesehen ist, der senkrecht zur Bewegungsrichtung der Betätigungsstangen verschiebbar angeordnet ist,
  • die erste Betätigungsstange eine Betätigungsrampe und die zweite Betätigungsstange eine Rastaufnahme aufweist und
  • der Sicherungsstift gegen die Rückstellkraft einer Feder mittels der Betätigungsrampe zum Eingriff in die Rastaufnahme gebracht wird, wenn der Verriegelungshebel in die Diebstahlsicherungsstellung verstellt ist.
This object is achieved in the device mentioned at the outset in that
  • the locking lever can be adjusted in the closing direction beyond the closed position to an anti-theft position in which the door lock can only be opened with the door key.
  • a locking pin is provided, which is arranged to be displaceable perpendicular to the direction of movement of the actuating rods,
  • the first actuating rod has an actuating ramp and the second actuating rod has a latching seat and
  • the locking pin is brought into engagement with the locking receptacle against the restoring force of a spring by means of the actuating ramp when the locking lever is moved into the anti-theft position.

Durch diese Gestaltung einer Zentralverriegelungsanlage kann man mit einem einzigen Stellelement ein Türschloß zwangsläufig in der richtigen Reihenfolge verriegeln und diebstahlsichern bzw. beim öffnen zunächst diebstahlentsichern und dann entriegeln. Da nur noch ein Stellelement erforderlich ist, benötigt die Zentralverriegelungsanlage bei einem pneumatisch arbeitenden Stellelement auch nur eine einzige Druckmittelzuführleitung, so daß sie einfach herstellbar und zu installieren ist. Die einzelnen Stellungen des Schlosses werden lediglich durch eine mehr oder minder hohe Druckbeaufschlagung des Betätigungselementes erreicht.With this design of a central locking system, you can inevitably lock and lock the door lock in the correct order with a single adjusting element or secure it against theft or unlock it and then unlock it when it is opened. Since only one actuating element is required, the central locking system also only requires a single pressure medium supply line in the case of a pneumatically operating actuating element, so that it can be produced and installed easily. The individual positions of the lock are only achieved by a more or less high pressurization of the actuating element.

Zweckmäßig ist es, wenn zusätzlich eine mechanische Kopplung vorgesehen ist, die von einem Türschlüssel bewegbar und mittels derer der Verriegelungshebel unabhängig vom Stellelement in die öffnungsstellung schwenkbar ist.It is expedient if a mechanical coupling is additionally provided which can be moved by a door key and by means of which the locking lever can be pivoted into the open position independently of the actuating element.

Anstelle der einteiligen Betätigungsstange kann auch eine zweiteilige Betätigungsstange vorgesehen werden, deren Teile gegen die Rückstellkraft einer Feder in Betätigungsrichtung relativ zueinander verschiebbar sind, wobei das erste Teil sowohl mit dem Stellelement als auch mit der mechanischen Kopplung verbunden ist und die Betätigungsrampe aufweist und das zweite Teil mit dem Verriegelungshebel verbunden ist.Instead of the one-piece actuating rod, a two-part actuating rod can also be provided, the parts of which can be displaced relative to one another against the restoring force of a spring in the actuating direction, the first part being connected both to the actuating element and to the mechanical coupling and having the actuating ramp and the second part is connected to the locking lever.

In weiterer Ausbildung der letztgenannten Ausführungsform kann noch vorgesehen werden, daß die Teile jeweils mit einem abgewinkelten Abschnitt über das andere Teil greifen, daß die Feder als Druckfeder ausgebildet und zwischen den abgewinkelten Abschnitten angeordnet ist und daß an jedem Teil ein Anschlag in Form eines Bundes vorgesehen ist, durch die die Verschiebung der beiden Teile relativ zueinander begrenzt ist.In a further embodiment of the latter embodiment, it can be provided that the parts each grip with an angled section over the other part, that the spring is designed as a compression spring and is arranged between the angled sections and that a stop in the form of a collar is provided on each part by which the displacement of the two parts is limited relative to each other.

Weitere Einzelheiten des Erfindungsgedankens werden anhand der in den Fig. 1 und 2 dargestellten Ausführungsbeispiele näher erläutert.

Further details of the inventive concept are explained in more detail with reference to the exemplary embodiments shown in FIGS. 1 and 2.
Fig. 1
shows a first embodiment of the inventive concept,
Fig. 2
shows a second embodiment of the inventive concept.

Die Fig. 1 zeigt schematisch ein pneumatisch arbeitendes Stellelement 1, welches ein Gehäuse 2 mit einem Druckmittelanschluß 3 hat. Im Gehäuse 2 ist eine von einer Membran 4 begrenzte Arbeitskammer 5 gebildet. An der Membran 4 ist ein oberes Ende einer ersten Betätigungsstange 6 befestigt, welche mit ihrem anderen Ende an einem Verriegelungshebel 7 angelenkt ist. Die Betätigungsstange 6 verläuft zweifach abgeknickt, wobei der abgeknickte Bereich eine schräg verlaufende Betätigungsrampe 8 bildet, gegen die ein Sicherungsstift 9 mit einem Ende anliegt. Der Sicherungsstift 9 ist hierzu mit einer Feder 10 zur Betätigungsstange 6 hin vorgespannt.Fig. 1 shows schematically a pneumatically operating actuator 1, which has a housing 2 with a pressure medium connection 3. A working chamber 5 defined by a membrane 4 is formed in the housing 2. On the membrane 4, an upper end of a first actuating rod 6 is attached, which is hinged at its other end to a locking lever 7. The actuating rod 6 runs twice bent, the bent region forming an inclined operating ramp 8 against which a locking pin 9 rests with one end. The locking pin 9 is biased by a spring 10 towards the actuating rod 6.

Die Zeichnung zeigt weiterhin einen Türknopf 11, der über eine zweite Betätigungsstange 12 mit einem freien Ende des Verriegelungshebels 7 verbunden ist. Diese Betätigungsstange 12 hat oberhalb des Sicherungsstiftes 9 eine Rastaufnahme 13.The drawing also shows a door knob 11 which is connected to a free end of the locking lever 7 via a second actuating rod 12. This actuating rod 12 has a locking receptacle 13 above the securing pin 9.

Beaufschlagt man das Stellelement 1 mit Druck bis zu einem festgelegten Druckniveau, dann verschiebt sich zunächst die Betätigungsstange 6 nur so weit in der Zeichnung gesehen nach unten, bis sich die Betätigungsrampe 8 soeben oberhalb des Sicherungsstiftes 9 befindet. Der Verriegelungshebel 7 schwenkt dabei in die strichpunktiert gezeigte Verriegelungsstellung. Dabei verschiebt sich auch die zweite Betätigungsstange 12 nach unten, wobei die Rastaufnahme 13 oberhalb des Sicherungsstiftes 9 bleibt. Soll die Zentralverriegelungsanlage diebstahlgesichert werden, dann ist die Arbeitskammer 5 des Stellelementes 1 mit höherem Druck zu beaufschlagen. Die Membran 4 verschiebt sich dann unter Mitnahme der Teile 6, 7, 12 weiter nach unten, so daß die Betätigungsrampe 8 den Sicherungsstift 9 gegen die Rückstellkraft der Feder 10 nach links in die Rastaufnahme 13 verschieben kann.If pressure is applied to the control element 1 up to a fixed pressure level, then the actuating rod 6 is first shifted downward only as far as seen in the drawing until the actuating ramp 8 is just above the locking pin 9. The locking lever 7 pivots in the locking position shown in dash-dotted lines. The second actuating rod 12 also moves downward, the latching receptacle 13 remaining above the locking pin 9. If the central locking system is to be secured against theft, then the working chamber 5 of the actuating element 1 must be subjected to higher pressure. The membrane 4 then moves with the entrainment of the parts 6, 7, 12 further downward, so that the actuating ramp 8 can move the locking pin 9 against the restoring force of the spring 10 to the left into the latching receptacle 13.

Baut man später in der Arbeitskammer 5 Unterdruck auf, dann wird die Betätigungsstange 6 zunächst so weit hochgezogen, daß der Sicherungsstift 9 von der Feder 10 wieder in die gezeigte Stellung verschoben werden kann. Bei weiterem Druckaufbau schwenkt der Verriegelungshebel 7 zurück in die in durchgezogenen Linien gezeigte Entriegelungsstellung.If you later build up vacuum 5 in the working chamber, then the actuating rod 6 is first pulled up so far that the locking pin 9 can be moved back into the position shown by the spring 10. If pressure builds up further, the locking lever 7 pivots back into the unlocking position shown in solid lines.

Für den Fall, daß der Schwenkwinkel des Verriegelungshebels 7 auf den Bereich "auf-zu" beschränkt bleiben soll, kann die Betätigungsstange 6 zweiteilig ausgebildet werden. Die Fig. 2 zeigt eine aus zwei Stangenteilen 14, 15 bestehende Betätigungsstange 6, wobei jeweils über das andere Stangenteil greifende, abgewinkelte Abschnitte 16, 17 vorgesehen sind. Eine Feder 18 stützt sich gegen die Unterseite des Abschnittes 16 des unteren Stangenteiles 15 und gegen die Oberseite des Abschnittes 17 des oberen Stangenteiles 14 auf. In der dargestellten Position liegen die beiden Stangenteile 14 und 15 an einem Bund 19 oberhalb des Abschnittes 16 und einem Bund 20 unterhalb des Abschnittes 17 an.In the event that the pivot angle of the locking lever 7 is to be limited to the "open-closed" area, the actuating rod 6 can be formed in two parts. 2 shows an actuating rod 6 consisting of two rod parts 14, 15, angled sections 16, 17 extending over the other rod part in each case being provided. A spring 18 is supported against the underside of section 16 of the lower rod part 15 and against the upper side of section 17 of the upper rod part 14. In the position shown, the two rod parts 14 and 15 rest on a collar 19 above section 16 and a collar 20 below section 17.

Dreht man an einem Schlüssel 21, so kann man unter Zusammendrücken der Feder 18 durch eine gestrichelt angedeutete, mechanische Kopplung 22 den Stangenteil 14 anheben, ohne daß dabei der mit dem Verriegelungshebel 7 verbundene Stangenteil 15 bewegt werden muß. Dadurch kommt es zu einer Verschiebung der in Fig. 1 gezeigten Betätigungsrampe 8, so daß der Sicherungsstift 9 mittels der Feder 10 aus der Rastaufnahme 13 herausgezogen und in Entsicherungsstellung verschoben werden kann.If you turn a key 21, you can press the spring 18 by a dashed mechanical coupling 22 to raise the rod part 14 without the rod part connected to the locking lever 7 15 must be moved. This results in a displacement of the actuating ramp 8 shown in FIG. 1, so that the locking pin 9 can be pulled out of the latching receptacle 13 by means of the spring 10 and moved into the unlocking position.
