Bei einer Verriegelungsvorrichtung für ein bewegliches Element, insbesondere eine Klappe oder eine Schublade, das in einer geschlossenen oder in einer geöffneten Position sein kann, wobei die Verriegelungsvorrichtung ein bewegliches Verriegelungselement zur Verriegelung des beweglichen Elementes in dessen geschlossener Position aufweist, ist es erfindungswesentlich, daß ein Schaltelement vorgesehen ist, das bei Druckausübung auf das bewegliche Element geschaltet wird, daß das Verriegelungselement so ausgebildet ist, daß bei Druckausübung auf das bewegliche Element ein mechanischer Kontakt zwischen dem Verriegelungselement und dem beweglichen Element aufgehoben wird und daß das Schaltelement mit einem Aktuator derart in Signalverbindung steht, daß bei Betätigung des Schaltelementes der Aktuator geschaltet wird, so daß das Verriegelungselement zwischen einer Verriegelungsposition und einer Freigabeposition wechselt. Mit dieser Schließvorrichtung ist eine besonders einfache Ausgestaltung möglich, da zunächst das bewegliche Element, insbesondere eine Klappe, bewegt werden muß, um das Schaltelement auszulösen, so daß dann das Schaltelement den Aktuator schaltet, der das Verriegelungselement in die Freigabeposition bringt, so daß dann die Klappe aufgeschwenkt werden kann. Da zunächst die Klappe bewegt wird und zwar so bewegt wird, daß das Verriegelungselement nicht mehr in Wirkverbindung mit der Klappe oder einem der Klappe zugeordnetem Verriegelungsstift ist, kann das Verriegelungselement danach besonders einfach bewegt werden, ohne daß Scherkräfte oder andere durch den Kontakt zur Klappe entstehende Reibungskräfte überwunden werden müßten. Der Aktuator kann dabei ein Motor, ein Getriebemotor, eine Kombination von Federvorrichtungen oder ein auf andere Weise Kraft ausübendes Element sein, das es ermöglicht, das Verriegelungselement von der Verriegelungsposition in die Freigabeposition und umgekehrt zu bewegen. Bevorzugt ist das Schaltelement ein Bestandteil der Verriegelungsvorrichtung und mit dem beweglichen Element derart in Wirkverbindung bzw. so positioniert, daß es bei Druckausübung auf das bewegliche Element geschaltet wird.In a locking device for a movable element, in particular a flap or drawer that is in a closed or in a can be in the open position, the locking device being a movable locking element for locking the movable Has element in its closed position, it is essential to the invention that a switching element is provided which at Pressure is switched on the movable element that the Locking element is designed so that when pressure is exerted on the movable element a mechanical contact between the Locking element and the movable element is lifted and that the switching element is in signal connection with an actuator, that when the switching element is actuated, the actuator is switched, so that the locking element between a locking position and a Release position changes. With this locking device one is special simple design possible because first the movable element, in particular a flap must be moved to the switching element trigger, so that the switching element then switches the actuator that the Brings locking element in the release position, so that then the flap can be swung open. Because the flap is moved first is moved so that the locking element is no longer in operative connection with the flap or a locking pin assigned to the flap, the locking element can then be moved particularly easily, without shear forces or others arising from contact with the flap Frictional forces would have to be overcome. The actuator can be a Motor, a gear motor, a combination of spring devices or a otherwise be a force-exerting element that enables the Locking element from the locking position to the release position and vice versa to move. The switching element is preferably a component the locking device and with the movable element in such a way Active connection or positioned so that when pressure is exerted on the movable element is switched.
Bevorzugt ist es jedoch, dem beweglichen Verriegelungselement eine Federeinrichtung zuzuordnen, die das Verriegelungselement in einer Verriegelungsposition hält und außerdem einen Aktuator zu verwenden, der mit dem Verriegelungselement derart in Wirkverbindung steht, daß der Aktuator das Verriegelungselement entgegen der von der Federeinrichtung aufgebrachten Kraft in eine Freigabeposition bringt. In einer solchen Schließvorrichtung kann ein besonders einfach ausgestalteter Aktuator eingesetzt werden, der nur in eine Richtung eine Kraft ausüben muß. However, it is preferred that the movable locking element Assign spring device that the locking element in a Holds locked position and also use an actuator that is in operative connection with the locking element such that the Actuator the locking element against that of the spring device applied force in a release position. In one Locking device can be a particularly simple actuator can be used, which only has to exert a force in one direction.
Zum Schließen der Klappe ist es in einer bevorzugten Ausgestaltung möglich, die Klappe manuell zuzudrücken, bis die Klappe mit dem Schaltelement in Wirkverbindung kommt, so daß der Aktuator geschaltet wird und das Verriegelungselement freigibt, so daß das Verriegelungselement wieder in die Verriegelungsposition wechseln kann. Bevorzugt ist jedoch eine Schaltung vorgesehen, die bei Betätigung des Schaltelements den Aktuator nur für eine vorbestimmte Zeitdauer aktiviert, so daß das Verriegelungselement für die vorbestimmte Zeitdauer in der Freigabeposition ist. Danach wechselt das Verriegelungselement automatisch wieder in die Verriegelungsposition, so daß beim Zudrücken der Klappe diese direkt in das Verriegelungselement einrasten kann.To close the flap, it is possible in a preferred embodiment close the flap manually until the flap with the switching element in Active connection comes, so that the actuator is switched and that Locking element releases, so that the locking element again in the Lock position can change. However, a circuit is preferred provided that the actuator for only one when the switching element is actuated predetermined period of time activated so that the locking element for the predetermined period of time is in the release position. Then that changes Locking element automatically returns to the locking position, see above that when you press the flap this directly into the locking element can snap into place.
Das Schaltelement kann in einer Vielzahl verschiedener Ausführungsformen realisiert werden. Es kann beispielsweise eine elektrische, elektromagnetische oder optische Detektion erfolgen, daß die schwenkbare Klappe in eine bestimmt Position gebracht worden ist. Mechanisch einfach und zuverlässig ist die Ausgestaltung des Schaltelements als Taster, der von der Klappe betätigt wird. Bevorzugt ist das Schaltelement, insbesondere der Taster, mit einer Schaltung verbunden, die erst nach einer vorbestimmten Zeitdauer anhaltenden Drucks auf den Taster ein Aktivierungssignal für den Aktuator abgibt. Auf diese Weise wird ein versehentliches Öffnen durch eine zufällige bzw. unabsichtliche Berührung der Klappe ausgeschlossen. Weiterhin ist es bevorzugt, daß die dem Taster zugeordnete Schaltung auf eine vorbestimmte Zeitdauer eingestellt ist, die etwa der vorbestimmten Zeitdauer entspricht, auf die eine dem Aktuator zugeordnete Schaltung eingestellt ist. Dabei wird erreicht, daß beim Öffnen zufällige Berührungen ausgeschlossen werden und die Klappe für eine Zeitdauer, von beispielsweise etwa einer Sekunde, gedrückt werden muß, um eine Freigabe zu erreichen. Die Schaltdauer des Aktuators ist etwa in der gleichen Größenordnung, so daß innerhalb dieser Zeit, die einer bewußten und gewollten Betätigung entspricht, die Klappe geöffnet werden kann und danach der Aktuator das Verriegelungselement wieder freigibt und die oben beschriebene rastende Verriegelung erfolgen kann. The switching element can be in a variety of different embodiments will be realized. For example, it can be electrical, electromagnetic or optical detection that the pivotable flap into a determined position has been brought. Mechanically simple and reliable is the design of the switching element as a button that from the flap is operated. The switching element, in particular the button, is preferred with a circuit connected after a predetermined period of time Continuous pressure on the button activates the actuator emits. This way, accidental opening by accidental or accidental contact with the flap is excluded. Furthermore it is preferred that the circuit assigned to the button to a predetermined Time period is set, which corresponds approximately to the predetermined period of time a circuit assigned to the actuator is set. Doing so achieved that accidental touches are excluded when opening and the flap for a period of time, for example about one second, must be pressed to get a release. The switching duration of the Actuator is roughly of the same order of magnitude, so within this Time that corresponds to a conscious and intentional activity, shut up can be opened and then the actuator the locking element releases again and the latching lock described above take place can.
In einer bevorzugten Ausgestaltung der Erfindung ist der Aktuator als Elektromagnet ausgebildet. Die Schließvorrichtung kommt daher vollständig ohne Motor aus und ist besonders einfach und kostengünstig herstellbar. In einer anderen bevorzugten Ausgestaltung der Erfindung ist die Verriegelungseinrichtung mit dem Schaltelement, insbesondere dem Taster, und dem Aktuator in einer Baugruppe ausgebildet. Die Schließeinrichtung kann daher als ein Element in oder an der Klappe montiert werden. Nach einer anderen bevorzugten Ausgestaltung der Erfindung ist der Aktuator in Schaltverbindung mit der Zentralverriegelung und/oder einem weiteren optionalen Steuergerät. Die dem Aktuator zugeordnete Schaltung ist dabei bevorzugt so ausgelegt, daß beim Schließen der Zentralverriegelung eine Betätigung des Aktuators und damit ein Öffnen des Deckels ausgeschlossen ist. Erst bei Freigabe der Zentralverriegelung wird eine Betätigung des Aktuators und damit ein Öffnen des Deckels wieder ermöglicht.In a preferred embodiment of the invention, the actuator is a Electromagnet trained. The locking device therefore comes completely without a motor and is particularly easy and inexpensive to manufacture. In Another preferred embodiment of the invention is the locking device with the switching element, in particular the button, and the Actuator formed in an assembly. The locking device can therefore can be mounted as an element in or on the flap. After another preferred embodiment of the invention is the actuator in switching connection with the central locking system and / or another optional control unit. The circuit associated with the actuator is preferably designed such that that when the central locking is closed, actuation of the actuator and thus opening the lid is excluded. Only when the Central locking is an actuation of the actuator and thus an opening of the lid again.
Das Schaltelement der Schließeinrichtung, insbesondere der Taster, ist bevorzugt so positioniert, daß er von einem an der Klappe angeordneten Verriegelungsstift betätigbar ist. Die Klappe steht dabei günstigerweise mit einer Federeinrichtung in Verbindung, die die Klappe in einer geöffneten Position hält, so daß der Verriegelungsstift der Klappe in der geschlossenen Position eingerastet ist und in diese eingerastete Position gedrückt ist. Erst wenn der Bediener eine gegen die Federkraft gerichtete Kraft aufbringt und die Klappe etwas nach innen drückt, kann der an der Klappe angeordnete Verriegelungsstift den Taster betätigen, wobei der Verriegelungsstift gleichzeitig die eingerastete Position verläßt und das Verriegelungselement der Verriegelungseinrichtung nach Betätigung des Tasters bei vernachlässigbar kleinen Scher- und Reibkräften bewegt wird.The switching element of the locking device, in particular the button, is preferably positioned so that it is arranged on the flap by one Locking pin can be actuated.

In Fig. 1 ist eine Prinzipskizze einer erfindungsgemäßen Schließvorrichtung
mit einer Klappe 1, die hier als Tankdeckel ausgebildet ist, und einer
Verriegelungseinrichtung 2 dargestellt. Die Klappe 1 ist an der in der Figur
linken Seite schwenkbar um eine Halterung 3 befestigt bzw. um eine durch die
Halterung 3 laufende Achse drehbar, wobei eine Federvorrichtung
vorgesehen ist, die die Klappe 1 entgegen der Richtung des Pfeils 6
vorspannt. Die Klappe 1 weist im rechten Endbereich, also in dem frei
schwenkbaren Endbereich, einen Verriegelungsstift 4 mit einem am Ende des
Verriegelungsstifts angeordneten Haken 5 auf. Der Haken 5 ist zum Eingriff in
die Verriegelungseinrichtung 2, genauer in ein Hakenelement 16 eines
Verriegelungselements 10, ausgelegt. Die Verriegelungseinrichtung 2 weist
ein um eine Achse 14 schwenkbares Verriegelungselement 10 auf, das hier in
seiner Verriegelungsposition mit der Bezugszahl 10 und in seiner zusätzlich
dargestellten Freigabeposition mit 10a gekennzeichnet ist. Die
Verriegelungseinrichtung 2 weist weiterhin einen als Elektromagnet
ausgebildeten Aktuator 12 und einen Taster 11 auf. Die
Verriegelungseinrichtung ist in einem zweiteiligen Gehäuse in einer
Baugruppe angeordnet. Der erste Gehäuseteil 18 nimmt das Schaltelement
11, das Verriegelungselement 10 und den Aktuator 12 auf. Das zweite
Gehäuseteil 13 umgibt insbesondere den Aktuator 12 von oben und unten und
bildet die Achse 14 für die Schwenkbewegung des Verriegelungselements 10
aus. In Fig. 1 is a schematic diagram of a locking device according to the invention
with a flap 1, which is designed here as a fuel cap, and one
In Fig. 2 ist die als Tankdeckel ausgebildete Klappe 1 in der
hochgeschwenkten Position dargestellt. In der Verriegelungseinrichtung 2 ist
das Verriegelungselement wieder in beiden Stellungen, also sowohl in der
Verriegelungsposition 10 als auch in der Freigabeposition 10a dargestellt.
Gleiche Teile sind mit gleichen Bezugszahlen gekennzeichnet.In Fig. 2, the flap 1 designed as a fuel cap is in the
shown swiveled position. In the
Der Bewegungsablauf wird unter Bezugnahme auf die drei in Fig. 3
dargestellten Positionen im Folgenden weiter erläutert. Die schematische
Darstellung gemäß der ersten Position in Fig. 3 entspricht der Darstellung in
Fig. 1, wobei das Verriegelungselement 10 in der Verriegelungsposition ist
und der Verriegelungsstift 4 mit seinem Haken 5 in das Hakenelement 16 des
Verriegelungselements 10 eingreift. Das Verriegelungselement 10 wird durch
eine Federeinrichtung 20, die am unteren Ende des Verriegelungselements
10, insbesondere unterhalb des Schwenkpunkts 14, angeordnet ist, in der
Verriegelungsposition gehalten. In der zweiten Position wird nun, wie in Fig. 1
mit Pfeil 6 angedeutet, manuell ein Druck auf die Klappe ausgeübt, so daß der
Verriegelungsstift 4 nach unten gedrückt wird und dort auch das als Taster
ausgebildete Schaltelement 11 betätigt. Daraufhin wird, wie in der dritten
Position in Fig. 3 dargestellt, der Aktuator 12 betätigt und zieht das
Verriegelungselement in die als 10a gekennzeichnete Freigabestellung. Damit
ist auch das Hakenelement 16 des Verriegelungselements 10 in der Figur
nach rechts gezogen, so daß die Klappe 1 nach Beendigung des manuell
ausgeübten Drucks um die in der Halterung 3 verlaufende Achse nach oben
schwenken kann.The sequence of movements is described with reference to the three in FIG. 3
positions explained further explained below. The schematic
Representation according to the first position in FIG. 3 corresponds to the representation in
Fig. 1, wherein the locking
Der Schließvorgang wird anhand der drei Darstellungen in Fig. 4 erläutert. Der
Aktuator 12 ist nur eine kurze Zeit betätigt und schaltet danach wieder aus, so
daß das Verriegelungselement 10 in der Verriegelungsposition ist. Beim
Schließen der Klappe 1 wird der Verriegelungsstift 4 nach unten geführt und,
wie in der zweiten Darstellung der Fig. 4 zu sehen ist, drückt das
Verriegelungselement 10 entlang der definierten Gleitflächen zur Seite, bis der
Haken 5 und das Hakenelement 16 ineinander einrasten können bzw.
einschnappen oder verhaken. The closing process is explained on the basis of the three representations in FIG. 4. The
In Fig. 5 ist die Schaltdauer in einem Diagramm dargestellt. Auf der x-Achse
ist die Zeit t angegeben und auf der y-Achse ist der Schaltzustand
aufgetragen. Im ersten, mit 25 gekennzeichneten Teil der dargestellten Kurve,
ist der Aktuator ausgeschaltet, da eine vorbestimmte Drückdauer 25 gegeben
sein muß, in der der Verriegelungsstift 4 das Schaltelement 11 beaufschlagt,
so daß eine zufällige oder unabsichtliche Berührung von einer gewollten
Öffnung unterschieden werden kann. Nachdem der Verriegelungsstift 4 für die
vorbestimmte Zeitdauer das Schaltelement 11 beaufschlagt hat, wird der
Aktuator 12 zum Zeitpunkt 26 eingeschaltet. Der Aktuator 12 ist dann für eine
vorbestimmte Zeitdauer 27 eingeschaltet, in der das Verriegelungselement in
der Freigabeposition 10a ist. In dieser Zeitdauer muß der Bediener den
Deckel freigeben bzw. den Druck auf den Deckel lösen, so daß der Deckel
hochschwenken kann. Nach Ende der Zeitdauer 27 schaltet der Aktuator zum
Zeitpunkt 28 aus und das Verriegelungselement geht entsprechend dem Zug
der Federeinrichtung 20 zurück in die Verriegelungsposition 10. Die
vorbestimmte Drückdauer 25 entspricht in ihrer zeitlichen Länge etwa der
vorbestimmten Zeitdauer 27, die der Aktuator geschaltet ist. Dies deshalb, da
letztlich beide Zeitdauern an eine bewußte menschliche Handlung angepaßt
sind. Die Zeitdauer ist jeweils etwa eine Sekunde.5, the switching duration is shown in a diagram. On the x axis
the time t is specified and the switching state is on the y-axis
applied. In the first part of the curve shown, marked with 25,
the actuator is switched off because there is a predetermined
