In other words, according to the invention, a 2-stroke operation with a single actuating means of e.g. provided from a vehicle interior.
Durch die erfindungsgemäß vorgesehene Steuerungsfunktion der Drehfalle für die Betätigung des Fanghakens werden eine über die Fallenkontur der Drehfalle realisierte Primärschließfunktion und eine über den Hakenabschnitt des Fanghakens realisierte Sekundärschließfunktion vorteilhaft in einem einzigen Bauteil (der Drehfalle) zusammengeführt.By inventively provided control function of the catch for the operation of the fishing hook a realized over the case contour of the rotary latch primary closing function and over the hook portion of the catch hook secondary closing function are advantageously combined in a single component (the catch).
Gemäß einer Ausführungsform der Erfindung sind der Fanghaken und die Drehfalle auf einer gemeinsamen Drehachse angeordnet.According to one embodiment of the invention, the catch hook and the rotary latch are arranged on a common axis of rotation.
Dies ermöglich eine besonders platzsparende und kostengünstige Herstellung der erfindungsgemäßen Schlossvorrichtung.This allows a particularly space-saving and cost-effective production of the lock device according to the invention.
Gemäß einer weiteren Ausführungsform der Erfindung weist die Drehfalle eine Mitnehmerkontur auf, wobei der Fanghaken einen Mitnehmerabschnitt aufweist, der so in Kopplungsbeziehung zur Mitnehmerkontur der Drehfalle steht, dass in der Entriegelungsposition der Drehfalle der Fanghaken gegen seine Federvorspannung aus einer zu der Verriegelungsposition der Drehfalle korrespondierenden Überfangposition dessen in seine Fangposition gestellt ist.According to a further embodiment of the invention, the catch has a Mitnehmerkontur, wherein the catch hook has a driver portion which is so in coupling relationship to Mitnehmerkontur the catch, that in the unlocked position of the catch of the fishing hook against its spring bias from a corresponding to the locking position of the catch overlapping position which is placed in its catch position.
Mit Überfangposition ist erfindungsgemäß eine Position gemeint, welche in Schließdrehrichtung noch hinter der Fangposition liegt, also über diese hinaus geht, und welche das sichernde Hintergreifen des Schließbügels durch den Hakenabschnitt gewährleistet.With overfalling position according to the invention, a position is meant, which in the closing direction of rotation is still behind the catching position, that goes beyond this, and which ensures the securing engagement behind the striker by the hook portion.
Durch die erfindungsgemäße Kopplungsbeziehung zwischen Mitnehmerabschnitt und Mitnehmerkontur wird auf einfache und robuste Weise ein Drehantrieb des Fanghakens entgegen seiner Federvorspannung realisiert, wobei die Drehfalle die Steuerung des Fanghakens übernimmt. Zu diesem Zweck stellt die Federvorspannung der Drehfalle bevorzugt ein höheres Federmoment bereit als die Federvorspannung des Fanghakens.Due to the inventive coupling relationship between the driver and Mitnehmerkontur a rotary drive of the fishing hook counter to its spring bias is realized in a simple and robust manner, the catch takes over the control of the fishing hook. For this purpose, the spring preload of the rotary latch preferably provides a higher spring torque than the spring preload of the catch hook.
Gemäß noch einer Ausführungsform der Erfindung weist die Schlossvorrichtung ferner eine Fanghakensperre auf, die federvorgespannt drehbar im Gehäuse gelagert ist, so dass in der Fangposition des Fanghakens ein Rastabschnitt der Fanghakensperre mit einer ersten Rastkontur des Fanghakens in Eingriff steht und den Fanghaken damit gegen dessen Federvorspannung in seiner Fangposition hält.According to yet another embodiment of the invention, the lock device further comprises a catch hook, which is spring-loaded rotatably mounted in the housing, so that in the catching position of the catching hook a latching portion of the catching hook catch is in engagement with a first latching contour of the catching hook and thus holds the catching hook against its spring preload in its catching position.
Auf diese Weise wird gewährleistet, dass der Fanghaken sicher in seiner Fangposition gehalten wird nachdem die Drehfalle durch die erste Entsperrbetätigung der Sperrklinke in ihre Entriegelungsposition gedreht hat. Daher kann z.B. ein über einen Bowdenzug mit der Sperrklinke verbundener Betätigungshebel im Fahrzeuginnenraum nach der ersten Entsperrbetätigung dessen komfortabel losgelassen bzw. ausgelassen werden, um zu einem gewünschten späteren Zeitpunkt die zweite Entsperrbetätigung dessen durchzuführen.In this way, it is ensured that the catch hook is securely held in its catching position after the catch has rotated by the first Entsperrbetätigung the pawl in its unlocked position. Therefore, e.g. a connected via a Bowden cable with the pawl operating lever in the vehicle interior after the first Entsperrbetätigung be released comfortably or omitted to perform at a desired later time, the second Entsperrbetätigung.
Gemäß noch einer weiteren Ausführungsform der Erfindung weist der Fanghaken eine zweite Rastkontur auf, so dass in der Freigabeposition des Fanghakens der Rastabschnitt der Fanghakensperre mit der zweiten Rastkontur des Fanghakens in Eingriff steht und den Fanghaken damit gegen dessen Federvorspannung in seiner Freigabeposition hält.According to yet another embodiment of the invention, the catch hook has a second latching contour, so that in the release position of the catch hook the catch portion of the catch hook is engaged with the second catch contour of the hook and thus holds the catch against its spring bias in its release position.
Auf diese Weise wird gewährleistet, dass der Fanghaken nach der zweiten Entsperrbetätigung der Sperrklinke sicher in seiner Freigabeposition gehalten wird, so dass ein freies und gefahrloses Ausheben des bevorzugt an einer Frontklappe wie einer Motorhaube des Kraftfahrzeugs angebrachten Schließbügels aus der Schlossvorrichtung ermöglicht wird.In this way, it is ensured that the catch hook is securely held in its release position after the second unlocking operation of the pawl, so that a free and safe lifting of preferably attached to a front flap such as a hood of the motor vehicle striker from the lock device is made possible.
Gemäß einer Ausführungsform der Erfindung ist die erste Rastkontur in Öffnungsdrehrichtung gesehen um eine vorbestimmte Winkeldistanz vor der zweiten Rastkontur angeordnet.According to one embodiment of the invention, as seen in the opening direction of rotation, the first latching contour is arranged in front of the second latching contour by a predetermined angular distance.
Durch diese Ausgestaltung der Erfindung wird vorteilhaft gewährleistet, dass die zweite Entsperrbetätigung der Sperrklinke einen größeren Bewegungshub aufweisen muss als die erste Entsperrbetätigung der Sperrklinke, womit eine zusätzliche Sicherung gegen versehentliches vollständiges Öffnen der erfindungsgemäßen Schlossvorrichtung bereitgestellt wird. Ein Fahrer des Kraftfahrzeugs muss, um den Fanghaken in seiner Freigabeposition zu fixieren, im Rahmen der zweiten Entsperrbetätigung bewusst einen größeren Bewegungshub ausführen, womit versehentliche Betätigungen weitestgehend ausgeschlossen werden können.This embodiment of the invention advantageously ensures that the second unlocking operation of the pawl must have a greater movement stroke than the first unlocking operation of the pawl, whereby an additional safeguard against accidental complete opening of the lock device according to the invention is provided. A driver of the motor vehicle must, in order to fix the catch hook in its release position, consciously carry out a larger movement stroke in the context of the second unlocking operation, whereby accidental actuations can be largely excluded.
Gemäß noch einer Ausführungsform der Erfindung weist die Drehfalle eine weitere Steuerkontur zum Steuern einer Bewegung der Fanghakensperre auf, wobei die weitere Steuerkontur zum Steuern so geformt ist, dass bei einer durch ein in eine Eindringrichtung in die Schlossvorrichtung entlang eines Eindringpfades Eindringen des Schließbügels verursachten gegen deren Federvorspannung gerichteten Drehung der Drehfalle in Schließrichtung der Rastabschnitt der Fanghakensperre außer Eingriff mit der ersten Rastkontur des Fanghakens gebracht wird, so dass der Fanghaken sich durch seine Federvorspannung in Schließrichtung bis auf eine zwischen seiner Fangposition und seiner Überfangposition liegende Zwischenfangposition drehen kann.According to yet another embodiment of the invention, the catch has a further control contour for controlling a movement of the catch hook, wherein the further control contour for controlling is formed so that at one of them by a penetrating in a direction of penetration into the lock device along a Eindringpfades penetration of the striker Spring bias directed rotation of the catch in the closing direction of the locking portion of the catch hook is disengaged from the first locking contour of the fishing hook is brought so that the fishing hook can rotate by its spring bias in the closing direction to a lying between its catching position and its overhung catching position.
Mit dieser Ausgestaltung der Erfindung wird auf einfache und robuste Weise sichergestellt, dass der Fanghaken beim Schließen der Schlossvorrichtung von der Drehfalle gesteuert in Schließdrehrichtung bewegbar ist bzw. bewegt wird.With this embodiment of the invention is ensured in a simple and robust manner that the catch hook when closing the lock device is controlled by the catch in the closing direction of rotation is movable or is moved.
Mit Zwischenfangposition ist erfindungsgemäß eine Position gemeint, welche in Schließdrehrichtung noch hinter der Fangposition liegt und welche das sichernde Hintergreifen des Schließbügels durch den Hakenabschnitt gewährleistet.With intermediate catching position according to the invention a position is meant, which is still behind the catching position in the closing direction of rotation and which ensures the securing engagement behind the striker by the hook portion.
Gemäß einer weiteren Ausführungsform der Erfindung ist der Fanghaken in seiner Zwischenfangposition durch die Kopplungsbeziehung seines Mitnehmerabschnitts mit der Mitnehmerkontur der Drehfalle gegen ein Weiterdrehen in die Überfangposition gesperrt.According to a further embodiment of the invention, the catch hook is locked in its intermediate catching position by the coupling relationship of its driver portion with the driver contour of the rotary latch against further rotation in the overlapping position.
Auf diese Weise wird durch die Drehfalle gesteuert sichergestellt, dass die Fallenkontur der Drehfalle den Schließbügel verriegelnd aufnehmen kann bevor der Fanghaken seine Überfangposition als Endposition in Schließdrehrichtung erreicht. Damit wird auf einfache und robuste Weise eine Behinderung der Drehfalle durch den Fanghaken ausgeschlossen.Controlled by the catch in this way it is ensured that the case contour of the catch can latchingly receive the striker before the catch hook reaches its overhanging position as an end position in the closing direction of rotation. This is a simple and robust way of disabling the catch by the fishing hook excluded.
Gemäß noch einer weiteren Ausführungsform der Erfindung weist die Schlossvorrichtung ferner eine Betätigungseinrichtung für die Fanghakensperre auf, wobei die Betätigungseinrichtung eine Fanghakensperrenklinke hat, die so im Eindringpfad angeordnet ist, dass die Fanghakensperrenklinke beim Eindringen des Schließbügels von diesem verdrängt wird und über eine mit ihr verbundene Fanghakensperrenkoppel die Fanghakensperre betätigt, so dass der Rastabschnitt der Fanghakensperre außer Eingriff mit der zweiten Rastkontur des Fanghakens gebracht wird und sich damit der Fanghaken durch seine Federvorspannung in Schließrichtung bis auf seine Fangposition drehen kann.According to yet another embodiment of the invention, the lock device further comprises an actuating device for the catch hook, wherein the actuating device has a catch hook pawl which is arranged in the penetration path, that the catch hook pawl is displaced during penetration of the striker from this and via a connected thereto Fanghakensperrenkoppel the catch hook lock actuated so that the locking portion of the catch hook lock is disengaged from the second locking contour of the fishing hook and thus the fishing hook can rotate by its spring bias in the closing direction to its catching position.
Mit der erfindungsgemäß vorgesehenen Betätigungseinrichtung wird auf einfache und sichere Weise gewährleistet, dass bei jeglichem auch nur geringen Einbringen des Schließbügels in die Schlossvorrichtung der Schließbügel zuverlässig von dem Fanghaken gesichert bzw. gehalten wird, so dass ein z.B. fahrtwindbasiertes Aufstellen der Frontklappe des Kraftfahrzeugs zuverlässig verhindert werden kann. Bevorzugt reicht für ein Auslösen der Betätigungseinrichtung das von Frontklappe und daran angebrachtem Schließbügel bereitgestellte Eigengewicht aus, so dass der Fanghaken in seine Fangposition fällt.With the invention provided for actuating device is ensured in a simple and secure manner, that with any even little introduction of the striker in the lock device, the striker is reliably secured or held by the fishing hook, so that a. Running wind based installation of the front door of the motor vehicle can be reliably prevented. Preferably, the self-weight provided by the front flap and the striker attached thereto is sufficient for triggering the actuating device, so that the catch hook falls into its catching position.
Gemäß einer Ausführungsform der Erfindung weist die Schlossvorrichtung ferner einen Auswerfer auf, der federvorgespannt drehbar im Gehäuse gelagert ist, so dass ein im Eindringpfad angeordneter Auswerfabschnitt des Auswerfers dem in die Schlossvorrichtung Eindringen des Schließbügels entgegenwirkt.According to one embodiment of the invention, the lock device further comprises an ejector, which is spring-loaded rotatably mounted in the housing, so that an ejection path arranged in the Einringpfad the ejector opposes the penetration into the lock device in the lock device.
Durch die vorteilhafte Integration des Auswerfers in die Schlossvorrichtung wird kostengünstig und montageaufwandsarm ein bequemes Ausheben des Schließbügels aus der Schlossvorrichtung durch z.B. per Hand Anheben der. Frontklappe ermöglicht.Due to the advantageous integration of the ejector in the lock device is inexpensive and easy to install a comfortable lifting the striker from the lock device by, for example, by hand lifting the. Front flap allows.
Bevorzugt ist dazu der Auswerfer derart federvorgespannt, dass der Schließbügel bei statischer Auflage auf dem Auswerfabschnitt auf einem Aushebehöhenniveau gehalten wird, das über einem Drehfallenhöhenniveau liegt, in dem sich die Fallenkontur der Drehfalle in deren Entriegelungsposition befindet, und das das in der Fangposition Hintergreifen des Schließbügels durch den Hakenabschnitt des Fanghakens ermöglicht.To this end, the ejector is preferably spring-biased in such a way that the striker is held at a Aushebehöhenniveau with static support on the Auswerfabschnitt, which is above a Drehfallenhöhenniveau in which the trap contour of the catch is in its unlocked position, and that in the catching position behind the striker allowed by the hook portion of the fishing hook.
Durch das etwas erhöhte Aushebehöhenniveau wird ein zum Eingreifen mit einer Hand ausreichend weiter Spalt zwischen Frontklappe und Frontgrill des Fahrzeugs bereitgestellt, so dass das Ausheben des Schließbügels noch bequemer erfolgen kann. Dadurch, dass auf dem Aushebehöhenniveau das Hintergreifen des Schließbügels durch den Hakenabschnitt des Fanghakens ermöglicht ist, behindert der Auswerfer nicht die Sicherungsfunktion des Fanghakens.Due to the slightly increased Aushebehöhenniveau one to intervene with a hand sufficiently wide gap between the front door and the front grill of the vehicle is provided so that the lifting of the striker can be made even more convenient. The fact that on the Aushebehöhenniveau the engagement of the striker is made possible by the hook portion of the fishing hook, the ejector does not hinder the safety function of the fishing hook.
Gemäß noch einer Ausführungsform der Erfindung weist die Schlossvorrichtung ferner eine elektrische Überwachungseinrichtung, die eingerichtet ist, einen Schließzustand der Schlossvorrichtung zu überwachen und entsprechende Schließzustandsignale auszugeben, und ein elektromechanisches Stellelement auf, welches eingerichtet ist, in Reaktion auf ein zur Freigabeposition des Fanghakens korrespondierendes Signal der Überwachungseinrichtung und ein zu einer Motorinbetriebnahme des Kraftfahrzeugs korrespondierendes Signal einer Fahrzeugsteuervorrichtung eine Stellbewegung auszuführen, so dass der Fanghaken aus seiner Freigabeposition in seine Fangposition verbracht wird.According to yet another embodiment of the invention, the lock device further comprises an electric monitor configured to monitor a lock state of the lock device and to output respective lock state signals, and an electromechanical actuator configured to respond in response to a signal corresponding to the release position of the catch hook Monitoring device and a corresponding to an engine startup of the motor vehicle signal of a vehicle control device perform an adjusting movement, so that the fishing hook is moved from its release position to its catching position.
Durch die Kombination von elektrischer Überwachungseinrichtung und elektromechanischem Stellelement wird vorteilhaft sichergestellt, dass bei einer Fehlbedienung (z.B. ein Fahrer des Kraftfahrzeugs entriegelt die Schlossvorrichtung mit zweimaligem Ziehen am Bedienhebel im Fahrzeuginnenraum und nimmt anschließend den Fahrbetrieb ohne vollständiges Schließen der Schlossvorrichtung wieder auf) bei offener Drehfalle der Fanghaken über das Stellelement bzw. Stellglied in die Fangposition (Hakenabschnitt ist am Schließbügel in Eingriff) gebracht wird und somit die Schließsicherheit gewährleistet wird.The combination of electrical monitoring device and electromechanical actuator is advantageously ensured that in a faulty operation (eg a driver of the vehicle unlocks the lock device with two pulls on the control lever in the vehicle interior and then resumes driving without complete closing of the lock device again) with open catch the Fishing hooks on the actuator or actuator in the catch position (hook portion is on the striker in engagement) is brought and thus the locking security is ensured.
