Abstract
Description
Die Erfindung bezieht sich auf eine Sperrvorrichtung mit einem in eine Schließanlage einschiebbaren Schließkörper, der in der Schließlage mit einem quer zur Einschubrichtung gegen Federkraft verschiebbaren Rastelement in Eingriff steht.The The invention relates to a locking device with a in one locking retractable closing body, the in the closed position with a transverse to the insertion direction against spring force Locking element is engaged.
Derartige Sperrvorrichtungen sind beispielsweise an Kofferraum- oder Motorraumhauben von Kraftfahrzeugen üblich und dort regelmäßig derart ausgestaltet, dass das Rastelement sowie der Schließkörper riegelnd zusammenwirken. Nach Einschub des Schließkörpers in die Schließlage muss also eine Entriegelungsvorrichtung betätigt werden, um den Schließkörper von der Sperrvorrichtung trennen zu können.such Locking devices are for example on trunk or engine compartment hoods of motor vehicles usual and there regularly configured, that the latching element and the closing body cooperate in a locking manner. After insertion of the closing body in the closed position So an unlocking device must be actuated to the closing body of to be able to disconnect the locking device.
Grundsätzlich kann es bei einer Sperrvorrichtung wünschenswert sein, deren Sperrfunktion steuern zu können.Basically it is desirable in a locking device be able to control their lock function.
Deshalb ist es Aufgabe der Erfindung, eine Sperrvorrichtung mit variablen Sperrverhalten zu schaffen.Therefore It is an object of the invention to provide a locking device with variable To create blocking behavior.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine die Federkraft bewirkende Feder mit ihrem rastelementfernen Ende gegen ein relativ stationäres Widerlager gespannt ist, welches zwischen einer Lage für hohe Federkraft und einer Lage für geringe Federkraft verstellbar ist.These Task is inventively characterized solved, that a spring causing the spring force with their detent element removed End against a relatively stationary one Abutment is curious, which between a position for high spring force and a location for low spring force is adjustable.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einer Sperrvorrichtung Mittel vorzusehen, mit denen die das Sperrverhalten bestimmende Rastkraft veränderbar ist. Damit wird die Möglichkeit geboten, bei Bedarf zwischen einer schwach oder einer stark verrasteten Schließlage zu wechseln. Darüber hinaus ist vorteilhaft, dass durch Veränderung der Federspannung am Rastelement auch die Dämpfung veränderbar ist, die beim Einschub des Schließkörpers in die Schließlage wirksam wird, denn die Federspannung bestimmt die Kraft, mit der das Rastelement eine Seitenfläche des Schließkörpers beaufschlagt, bzw. den Reibwiderstand, der beim Einschub des Schließkörpers in die Schließlage überwunden werden muss.The The invention is based on the general idea of a locking device Provide means with which the locking behavior determining latching force variable is. This provides the opportunity if necessary, between a weak or a strongly locked closed position switch. About that It is also advantageous that by changing the spring tension on Locking element and the damping variable is, which is effective when inserting the closing body in the closed position is, because the spring tension determines the force with which the locking element a side surface the closing body acted upon, or the frictional resistance, the insertion of the closing body in overcome the closed position must become.
Bei entsprechender Formung der miteinander zusammenwirkenden Teile von Rastelement und Schließkörper kann gemäß einer ersten bevorzugten Ausführungsform der Erfindung vorgesehen sein, dass der Schließkörper und das Rastelement sowohl bei geringer als auch bei hoher Federspannung auslösbar rastend zusammenwirken. Im Ergebnis wird also nur die Stärke der Verrastung des Schließkörpers in seiner durch die Sperrvorrichtung vorgegebenen Schließlage verändert, der Schließkörper lässt sich also aus dieser Endlage immer, allerdings mit unterschiedlichem Kraftaufwand, auslösen.at appropriate shaping of the cooperating parts of Locking element and closing body can according to a first preferred embodiment be provided of the invention, that the closing body and the locking element both at less cooperable triggering latching at high spring tension. The result is only the strength the locking of the closing body in changed its predetermined by the locking device closing position, the Closing body can be So from this end position always, but with different Force, trigger.
Stattdessen ist es gemäß einer weiteren bevorzugten Ausführungsform auch möglich, dass der Schließkörper und das Rastelement bei geringer Federspannung auslösbar rastend und bei hoher Federspannung mit Selbsthemmung riegelnd zusammenwirken. In diesem Falle lässt sich also der Schließkörper bei hoher Federspannung auch mit hohem Kraftaufwand nicht mehr aus der durch den Aufnahmekörper vorgegebenen Endlage auslösen.Instead is it according to one another preferred embodiment also possible, that the closing body and the latching element at low spring tension releasably latching and at high Spring tension with self-locking locking cooperate. In this Trap So join the closing body high spring tension even with high effort no longer out of the through the receiving body trigger predetermined end position.
Gemäß einer konstruktiv besonders bevorzugten Ausführungsform kann zur Verstellung des relativ stationären Widerlagers der Feder eine Magnetanordnung vorgesehen sein, welche einen Permanentmagnet aufweist, der mit einer Elektromagnetanordnung zusammenwirkt, die je nach elektrischer Stromrichtung ein das Magnetfeld des Permanentmagnetes verstärkendes oder ein dem Magnetfeld des Permanentmagnetes entgegenwirkendes Magnetfeld erzeugt.According to one structurally particularly preferred embodiment can for adjustment of the relatively stationary Abutment of the spring may be provided a magnet assembly, which a permanent magnet having an electromagnet arrangement cooperates, depending on the electric current direction, the magnetic field of the permanent magnet reinforcing or a magnetic field of the permanent magnet counteracting Magnetic field generated.
Diese Magnetanordnung kann nun mit einem am relativ stationären Widerlager der Feder angeordneten Stößel bzw. Anker aus magnetisierbarem Material zusammenwirken: Wenn die Elektromagnetanordnung in das Magnetfeld des Permanentmagnetes verstärkender Richtung elektrisch bestromt wird, wird der Stößel bzw. Anker in eine Endlage gebracht, in der der Stößel bzw. Anker an einem Pol des Permanentmagnetes magnetisch haftend anliegt und die Feder mit hoher Federkraft gespannt wird. Diese Lage bleibt bei Abschaltung der elektrischen Bestromung der Elektromagnetanordnung selbsthaftend aufrechterhalten, weil die Federkraft nicht ausreicht, den Stößel bzw. Anker vom genannten Pol des entsprechend starken Permanentmagnetes zu entfernen. Erst wenn die Elektromagnetanordnung in dem Magnetfeld des Permanentmagnetes entgegenwirkender Richtung elektrisch bestromt wird, verschiebt die Feder den Stößel bzw. Anker in eine durch einen Anschlag vorgegebene Endlage, in der die Feder nur mit geringer Federkraft gespannt wird. Auch diese Endlage bleibt bei Abschaltung der elektrischen Bestromung selbsthaltend aufrechterhalten, weil das Magnetfeld des Permanentmagnetes allein nicht ausreicht, den Stößel bzw. Anker gegen die Kraft der Feder zu bewegen. Die Feder hat also eine Doppelfunktion. Einerseits beaufschlagt sie das Rastelement in Richtung der Eingriffslage, andererseits spannt sie das relativ stationäre Federwiderlager in Richtung der Endlage für geringe Federkraft.These Magnet arrangement can now with a relatively stationary abutment the spring arranged plunger or Armature of magnetizable material interact: When the electromagnet assembly in the magnetic field of the permanent magnet amplifying direction electrically is energized, the plunger or Anchor brought into an end position in which the plunger or armature to a pole of the permanent magnet is magnetically adhesive and the spring with high spring force is stretched. This situation remains at shutdown the electrical energization of the electromagnet assembly self-adhesive, because the spring force is insufficient, the plunger or anchor of the above Pol to remove the correspondingly strong permanent magnet. First when the electromagnet assembly in the magnetic field of the permanent magnet counteracting direction is electrically energized, shifts the Spring the plunger or Anchor in a predetermined by a stop limit position in which the Spring is tensioned only with low spring force. Also this end position remains self-holding when switching off the electrical current supply maintained because the magnetic field of the permanent magnet alone is not enough, the plunger or Anchor to move against the force of the spring. The spring has one Dual function. On the one hand, it acts on the locking element in the direction the engagement position, on the other hand it spans the relatively stationary spring abutment in the direction of the final position for low spring force.
