Description
Die Erfindung betrifft eine Einrichtung zur Sicherung eines Kraftfahrzeuges vor unbefugtem Öffnen, insbesondere der Fahrzeugtür, mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen.The invention relates to a device for securing a motor vehicle against unauthorized opening, in particular the vehicle door, with the features mentioned in the preamble of claim 1.
In Verbindung mit der ständigen Weiterentwicklung von Kraftfahrzeugen findet auch in zunehmendem Maß die Ausgestaltung von Kraftfahrzeugschlössern Berücksichtigung, so auch unter dem Gesichtspunkt der Diebstahl- oder Aufbruchsicherheit. Dabei nehmen zwar elektronische Einrichtungen einen breiten Raum ein, aber auch mechanische Einrichtungen zur Erhöhung der Diebstahl- beziehungsweise Aufbruchsicherheit werden stetig weiterentwickelt.In connection with the constant development of motor vehicles, the design of motor vehicle locks is also increasingly being taken into account, including from the point of view of theft or break-up security. Although electronic devices occupy a large space, but also mechanical devices to increase theft or Aufbruch security are constantly evolving.
Grundsätzlich wird bei der Weiterentwicklung von Kraftfahrzeugschlössern im Wesentlichen immer wieder von der allgemein bekannten Ausbildung ausgegangen, gemäß der die in die Fahrzeugtür integrierte Schließvorrichtung aus einem in einem Systemgehäuse angeordneten Schließzylinder besteht. Dabei besitzt der Schließzylinder eine Zylinderbuchse, in der ein drehbar gelagerter Zylinderkern angeordnet ist. Zu diesem gehören radial verschiebbar angeordnete, federbelastete Zuhaltungen in Form von Plättchen, die bei Verriegelung durch die Schließvorrichtung in entsprechende Kanäle der Zylinderbuchse eingreifen. Wird der zugehörige Schlüssel des Kraftfahrzeuges in den Schließzylinder eingesteckt, so werden die Plättchen der Zuhaltungen derart einsortiert, dass der Zylinderkern gegenüber der Zylinderbuchse drehbar ist. Diese Drehbewegung des Zylinderkernes wird über ein langgestrecktes Bauteil, dem Paddel, das über eine Kupplung mit dem Zylinderkern mittelbar oder unmittelbar in Verbindung steht, auf den Schließmechanismus der Schließvorrichtung des Kraftfahrzeuges übertragen. Erfolgt ein Herausziehen des zugehörigen Schlüssels des Kraftfahrzeuges aus dem Schließzylinder, so erfolgt eine Verriegelung, indem die Plättchen der Zuhaltungen in entsprechende Kanäle der Zylinderbuchse des Schließzylinders eingreifen.In principle, in the further development of motor vehicle locks, it is generally assumed that the generally known design is used, according to which the locking device integrated in the vehicle door consists of a lock cylinder arranged in a system housing. In this case, the lock cylinder has a cylinder liner in which a rotatably mounted cylinder core is arranged. This includes radially displaceably arranged, spring-loaded tumblers in the form of platelets, which engage in locking by the locking device in corresponding channels of the cylinder liner. If the associated key of the motor vehicle is inserted into the lock cylinder, the plates of the tumblers are sorted in such a way that the cylinder core is rotatable relative to the cylinder liner. This rotational movement of the cylinder core is transmitted to the closing mechanism of the locking device of the motor vehicle via an elongated component, the paddle, which is directly or indirectly connected to the cylinder core via a coupling. If a withdrawal of the associated key of the motor vehicle from the lock cylinder, so there is a lock by the plates of the tumblers engage in corresponding channels of the cylinder liner of the lock cylinder.
Ausgehend von dieser grundsätzlichen Ausbildung der in die Fahrzeugtür integrierten Schließvorrichtung sind die vielfältigsten mechanischen Einrichtungen bekannt, durch die eine Sicherung von Kraftfahrzeugen vor unbefugtem Öffnen der Fahrzeugtür erfolgt. Unabhängig davon, wie nun diese mechanischen Einrichtungen ausgebildet sind, sind sie jedoch im Wesentlichen immer wieder nur dazu geeignet, um bei hohen Zugkräften eine sichere Arretierung des Schließzylindergehäuses in der Schließzylinderaufnahme zu ermöglichen. Ist ein gewaltsames Öffnen der Fahrzeugtür und damit verbunden ein Diebstahl des Kraftfahrzeuges vorgesehen, indem von außen schlagartig auf den Schließzylinder eine große Kraft einwirkt, derart, dass ein Hereinschlagen des Schließzylinders ins Innere der Fahrzeugtür erfolgt, was mit dem Zugang an das Türschloss verbunden ist, so sind die bekannten mechanischen Einrichtungen nicht dazu geeignet, um unter Berücksichtigung dieser auf den Schließzylinder einwirkenden Kraft einen Diebstahl des Kraftfahrzeuges zu verhindern.Based on this basic design of the integrated in the vehicle door locking device, the most diverse mechanical devices are known, done by securing motor vehicles against unauthorized opening of the vehicle door. Regardless of how now these mechanical devices are formed, however, they are essentially always suitable only to allow for high tensile forces secure locking of the lock cylinder housing in the lock cylinder receptacle. Is a violent opening of the vehicle door and the associated theft of the motor vehicle provided by acting suddenly on the outside of the lock cylinder a large force, such that a knocking of the lock cylinder takes place inside the vehicle door, which is connected to the access to the door lock, so the known mechanical devices are not suitable to prevent theft of the motor vehicle taking into account this force acting on the lock cylinder.
Aus dem Stand der Technik ist die Druckschrift
Bekannt ist ferner die Druckschrift
Der Erfindung liegt daher die Aufgabe zugrunde, eine noch robustere Einrichtung zur Sicherung eines Kraftfahrzeuges vor unbefugtem Öffnen, insbesondere der Fahrzeugtür, zu schaffen, durch die ein Hereinschlagen des Schließzylinders in das Innere der Fahrzeugtür und damit der Zugang an das Türschloss verhindert und somit die Diebstahlsicherheit erhöht wird.The invention is therefore an object of the invention to provide an even more robust device for securing a motor vehicle against unauthorized opening, in particular the vehicle door, prevented by the breaking of the lock cylinder in the interior of the vehicle door and thus access to the door lock and thus theft security is increased.
Diese Aufgabe wird erfindungsgemäß durch eine Einrichtung mit den im Anspruch 1 genannten Merkmalen gelöst.This object is achieved by a device having the features mentioned in claim 1.
Ausgangspunkt der Erfindung ist eine Einrichtung zur Sicherung eines Kraftfahrzeuges vor unbefugtem Öffnen einer Fahrzeugtür, in die eine Schließvorrichtung integriert ist, bei der in einem Systemgehäuse ein Schließzylinder angeordnet ist, der aus einem in einer Zylinderbuchse drehbar gelagerten Zylinderkern besteht, der radial verschiebbar angeordnete, federbelastete Zuhaltungen besitzt, die bei Verriegelung durch die Schließvorrichtung in entsprechende Kanäle der Zylinderbuchse eingreifen, wobei die Drehbewegung des Zylinderkernes um die Achse des Schließzylinders über ein langgestrecktes Verbindungsteil, das mittelbar oder unmittelbar mit dem Zylinderkern in Wirkverbindung steht, auf den Schließmechanismus der Schließvorrichtung übertragen wird, so dass der Schließzylinder und damit der Zylinderkern mit seinem langgestreckten, mit dem Schließmechanismus in Wirkverbindung stehenden Verbindungsteil bei Einwirkung, insbesondere einer großen, von außen auf den Schließzylinder schlagartig einwirkenden Kraft in seiner axialen Position durch eine eine nach innen gerichtete axiale Verschiebung des Schließzylinders verhindernde mechanische Sperre im Wesentlichen unveränderbar ist, wobei die mechanische Sperre im Bereich der Verbindung des Zylinderkernes des Schließzylinders mit dem langgestreckten Verbindungsteil vorgesehen ist, und das langgestreckte Bauteil mit dem Zylinderkern über eine Kupplung in Verbindung steht.The starting point of the invention is a device for securing a motor vehicle against unauthorized opening a vehicle door, in which a closing device is integrated, in which a lock cylinder is arranged in a system housing, which consists of a cylinder core rotatably mounted in a cylinder core, the radially displaceable arranged spring-loaded Has tumblers, which engage in locking by the locking device in corresponding channels of the cylinder liner, wherein the rotational movement of the cylinder core about the axis of the lock cylinder via an elongate connecting part, directly or indirectly with the cylinder core in Operative connection is transmitted to the closing mechanism of the closing device, so that the lock cylinder and thus the cylinder core with its elongated, with the closing mechanism operatively connected to the connecting member upon action, in particular a large, abruptly acting from the outside on the lock cylinder force in its axial position a mechanical lock preventing an inward axial displacement of the lock cylinder is substantially invariable, the mechanical lock being provided in the region of connection of the cylinder core of the lock cylinder with the elongate connection part, and the elongate member being in communication with the cylinder core via a coupling.
- zu der Kupplung ein Gehäuse gehört, das einen mit einem Gewinde versehenen Einsatz der Kupplung aufnimmt, in den das langgestreckte Bauteil eingeschraubt ist,to the clutch is a housing which receives a threaded insert of the coupling into which the elongate member is screwed,
- wobei das Systemgehäuse zur Bildung der mechanischen Sperre eine den Bereich der Verbindung des Zylinderkernes des Schließzylinders mit dem langgestreckten Verbindungsteil im Wesentlichen übergreifende, sich axial erstreckende Anformung besitzt, die an ihrem zum Zylinderkern gerichteten freien Ende eine in Richtung der Achse des Schließzylinders verlaufende, einen ersten Anschlag bildende Einengung besitzt, durch die der Schließzylinder in seiner axialen Position begrenzt ist,wherein the system housing for forming the mechanical lock has an axially extending Anformung the area of the connection of the cylinder core of the lock cylinder with the elongated connecting part substantially extending, at its directed to the cylinder core free end extending in the direction of the axis of the lock cylinder, a first Stop forming constriction has, by which the lock cylinder is limited in its axial position,
- wobei die Anformung in Richtung des langgestreckten Verbindungsteiles ausgebildet ist,wherein the Anformung is formed in the direction of the elongated connection part,
- so dass zur Begrenzung der axialen Position des Schließzylinders die den ersten Anschlag bildende Einengung der axial sich erstreckenden Anformung des Systemgehäuses mit einem zweiten Anschlag in Wirkverbindung steht, der mit dem Gehäuse der Kupplung in Verbindung steht, und der nach Art eines Flansches am äußeren Umfang des Gehäuses der Kupplung angeordnet ist, über die das langgestreckte Verbindungsteil mit dem Zylinderkern des Schüeßzylinders verbunden ist.so that for limiting the axial position of the lock cylinder, the first stop forming constriction of the axially extending Anformung the system housing is in operative connection with a second stop, which is in communication with the housing of the clutch, and the manner of a flange on the outer circumference of Housing of the clutch is arranged, via which the elongated connecting part is connected to the cylinder core of the Schüeßzylinders.
Dadurch wird erreicht, dass ein Hereinschlagen des Schließzylinders in das Innere der Fahrzeugtür und damit der Zugang an das Türschloss verhindert und somit die Diebstahlbeziehungsweise Aufbruchsicherheit erhöht wird. Der schlagartig von außen auf den Schließzylinder einwirkenden Kraft stehen praktisch über den Schließzylinder relativ große Kräfte gegenüber, die aus der Anordnung der eine axiale Verschiebung des Schließzylinders verhindernden mechanischen Sperre resultieren.This ensures that a penetration of the lock cylinder into the interior of the vehicle door and thus prevents access to the door lock and thus the theft or breakdown security is increased. The abruptly acting from the outside on the lock cylinder force are practically opposite to the lock cylinder relatively large forces resulting from the arrangement of an axial displacement of the lock cylinder preventing mechanical lock.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen. Obwohl sich für die Anordnung der mechanischen Sperre die verschiedensten Varianten anbieten, ist unter Berücksichtigung dessen, dass der umbaute Raum des Schließzylinders nicht zu vergrößern ist, eine Anordnung der mechanischen Sperre besonders vorteilhaft, gemäß der die mechanische Sperre im Bereich der Verbindung des Zylinderkernes des Schließzylinders mit dem langgestreckten Bauteil, dem Paddel, vorgesehen ist.Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics. Although a variety of variants are available for the arrangement of the mechanical lock, taking into account that the enclosed space of the lock cylinder is not to be increased, an arrangement of the mechanical lock is particularly advantageous, according to which the mechanical lock in the region of the connection of the cylinder core of the lock cylinder is provided with the elongate member, the paddle.
Bei dieser Anordnung der mechanischen Sperre besitzt zu ihrer Bildung das den Schließzylinder aufnehmende Systemgehäuse eine den Bereich der Verbindung des Zylinderkernes des Schließzylinders mit dem langgestreckten Bauteil im Wesentlichen übergreifende, axial sich erstreckende Anformung, die an ihrem freien Ende eine in Richtung der Achse des Schließzylinders verlaufende, einen ersten Anschlag bildende Einengung besitzt, durch die der Schließzylinder in seiner axialen Position hinsichtlich einer nach innen gerichteten axialen Verschiebung begrenzt ist. Dabei kann die axial sich erstreckende, den Bereich der Verbindung des Zylinderkerns des Schließzylinders mit dem langgestreckten Verbindungsteil übergreifende Anformung an ihrem äußeren Umfang in Richtung des langgestreckten Verbindungsteiles bei Erzielung einer großen Stabilität gegen die aus dem Hereinschlagen des Schließzylinders in das Innere der Fahrzeugtür resultierenden Kraft konisch verjüngend ausgebildet sein, während sie an ihrem inneren Umfang unter Berücksichtigung der durch sie überdeckenden Bauteile vorwiegend zylindrisch auszubilden ist.In this arrangement, the mechanical lock has to its formation the lock cylinder receiving system housing a the region of the connection of the cylinder core of the lock cylinder with the elongate member substantially cross, axially extending Anformung, which extends at its free end in the direction of the axis of the lock cylinder has a first stop forming constriction by which the lock cylinder is limited in its axial position with respect to an inwardly directed axial displacement. In this case, the axially extending, the region of the connection of the cylinder core of the lock cylinder with the elongated connecting part cross-conformation on its outer periphery in the direction of the elongated connection member to achieve great stability against the force resulting from the blowing of the lock cylinder into the interior of the vehicle door conical be formed tapered, while it is predominantly cylindrical form at its inner periphery, taking into account the components covering them.
Ausgehend von der einen ersten Anschlag bildenden Einengung der axial sich erstreckenden Anformung steht zur Begrenzung der axialen Position des Schließzylinders die den ersten Anschlag bildende Einengung der Anformung des Systemgehäuses mit einem zweiten Anschlag in Wirkverbindung, der nach Art eines Flansches am äußeren Umfang eines Gehäuses der Kupplung angeordnet ist, über die das langgestreckte Verbindungsteil mit dem Zylinderkern des Schließzylinders verbunden ist.Starting from the first stop forming constriction of the axially extending Anformung is to limit the axial position of the lock cylinder forming the first stop narrowing of the molding of the system housing with a second stop in operative connection, in the manner of a flange on the outer circumference of a housing of the clutch is arranged, via which the elongated connecting part is connected to the cylinder core of the lock cylinder.
Zweckmäßigerweise besteht zwecks weiterer Erhöhung der Stabilität gegen die aus dem Hereinschlagen des Schließzylinders in das Innere der Fahrzeugtür resultierende Kraft das Systemgehäuse und damit die den Bereich der Verbindung des Zylinderkernes des Schließzylinders mit dem langgestreckten Verbindungsteil übergreifende, axial sich erstreckende Anformung mit ihrer den ersten Anschlag bildenden Einengung aus einem druckbelastbaren Material. Aus diesem druckbelastbaren Material sollte aber auch zumindest der zweite Anschlag bestehen, der nach Art eines Flansches am äußeren Umfang des Gehäuses der Kupplung angeordnet ist. Dabei kann als druckbelastbares Material nicht nur ein harter Kunststoff, sondern auch Metall eingesetzt werden. Kommt Metall zur Anwendung, so werden die Anforderungen hinsichtlich einer hohen Druckbelastung besonders berücksichtigt, wenn als druckbelastbares Material Zinkdruckguss vorgesehen ist.Conveniently, for the purpose of further increasing the stability against the resulting from the hammering of the lock cylinder in the interior of the vehicle door force the system housing and thus the area of the connection of the cylinder core of the lock cylinder with the elongated connecting part cross, axially extending Anformung with their first stop forming Narrowing of a pressure-resistant material. For this pressure-resistant material but should also be at least the second stop, which in the manner of a flange on the outside Circumference of the housing of the coupling is arranged. Not only a hard plastic, but also metal can be used as pressure-resistant material. If metal is used, the requirements with regard to a high pressure load are taken into special consideration when zinc-pressure casting is intended as a pressure-resistant material.
Selbstverständlich werden die durch die Erfindung beabsichtigten Wirkungen nicht nur dann erzielt, wenn die erfindungsgemäße Einrichtung bei Fahrzeugtüren eingesetzt wird, sondern diese Wirkungen treten auch dann ein, wenn die Einrichtung beispielsweise in die Schließvorrichtung der Heckklappe von Kraftfahrzeugen integriert ist.Of course, the effects intended by the invention are achieved not only when the device according to the invention is used in vehicle doors, but these effects occur even when the device is integrated, for example, in the closing device of the tailgate of motor vehicles.
Die Erfindung wird nachfolgend in einem Ausführungsbeispiel anhand der zugehörigen Zeichnung, die eine Schließvorrichtung einer Fahrzeugtür in einer Schnittdarstellung zeigt, näher erläutert.The invention will be explained in more detail in an embodiment with reference to the accompanying drawing, which shows a closing device of a vehicle door in a sectional view.
Die Figur zeigt einen Schnitt einer Schließvorrichtung 1 der Fahrzeugtür eines Kraftfahrzeuges. Dabei besteht die Schließvorrichtung 1 aus einem in einem Systemgehäuse 2 angeordneten Schließzylinder 3, der eine Zylinderbuchse 4 besitzt, in der ein drehbar gelagerter Zylinderkern 5 angeordnet ist. Am äußeren Umfang des Zylinderkernes 5 sind radial verschiebbar angeordnete, federbelastete Zuhaltungen 6 vorgesehen, die die Form von Plättchen besitzen und bei Verriegelung durch die Schließvorrichtung 1 in am inneren Umfang der Zylinderbuchse 4 vorgesehene Kanäle 7 eingreifen. Wird der zugehörige Schlüssel des Kraftfahrzeuges über den Schlüsselkanal 8 in den Zylinderkern 5 und damit in den Schließzylinder 3 eingeführt, so werden die federbelasteten Zuhaltungen 6, die vor dem Einführen des Schlüssels radial nach außen gedrückt werden, einsortiert, so dass der Zylinderkern 5 gegenüber der ihn umgebenden Zylinderbuchse 4 um die Achse 9 des Schließzylinders 3 drehbar ist, so dass bei Drehung des Zylinderkernes 5 eine Betätigung des mechanisch mit dem Zylinderkern 5 gekoppelten, nicht weiter dargestellten Schließmechanismus beispielsweise zum Öffnen der Fahrzeugtür des Kraftfahrzeuges erfolgt. Ist der Schlüssel abgezogen, so erfolgt die Verriegelung, da die federbelasteten Zuhaltungen 6 nunmehr unter Berücksichtigung der einwirkenden Kraft in die Kanäle 7 der Zylinderbuchse 4 eingreifen.The figure shows a section of a closing device 1 of the vehicle door of a motor vehicle. Here, the closing device 1 consists of a arranged in a system housing 2
Übertragen wird die Drehbewegung des Zylinderkernes 5 des Schließzylinders 3 auf den Schließmechanismus der Schließvorrichtung 1 durch das langgestreckte, nur teilweise dargestellte Verbindungsteil 10, dem Paddel. Dabei steht dieses mit dem Zylinderkern 5 über eine Kupplung 11 in Verbindung, zu der ein Gehäuse 12 gehört, das einen mit einem Gewinde versehenen Einsatz 13 aufnimmt, in den das langgestreckte Bauteil 10 einschraubbar ist.The rotational movement of the cylinder core 5 of the
Um nun ein Hereinschlagen des Schließzylinders 3 in das Innere der Fahrzeugtür durch die dabei wirksame Kraft F1 zu verhindern, ist der Schließzylinder 3 und damit der Zylinderkern 5 sowie das mit dem Schließmechanismus der Schließvorrichtung 1 in Wirkverbindung stehende langgestreckte Verbindungsteil 10 in seiner axialen Position durch eine eine nach innen gerichtete axiale Verschiebung des Schließzylinders 3 verhindernde mechanische Sperre 14 festgelegt. Dabei besitzt zur Bildung der mechanischen Sperre 14 das Systemgehäuse 2 eine axial sich erstreckende Anformung 15, die an ihrem freien Ende 16 eine einen ersten Anschlag 17 bildende Einengung 18 besitzt. Dieser erste Anschlag 17 steht mit einem zweiten Anschlag 19 in Wirkverbindung, der nach Art eines Flansches 20 am äußeren Umfang des Gehäuses 12 der Kupplung 11 angeordnet ist. Ist ein Hereinschlagen des Schließzylinders 3 in das Innere der Fahrzeugtür beabsichtigt, so wird dieses Hereinschlagen durch das Auftreffen des zweiten, mit dem Gehäuse 12 in Verbindung stehenden Anschlages 19 auf den ersten, durch die Einengung 18 der axial sich erstreckenden Anformung 15 gebildeten Anschlag 17 verhindert. Da bei diesem Auftreffen große Kräfte wirksam werden, besteht sowohl das Systemgehäuse 2 und damit auch die axial sich erstreckende Anformung 15 mit ihrem ersten Anschlag 17 als auch der zweite Anschlag 19 und somit auch das Gehäuse 12, das den mit einem Gewinde versehenen Einsatz 13 der Kupplung 11 aufnimmt, aus Zinkdruckguss. Dabei ist die axial sich erstreckende Anformung 15 an ihrem äußeren Umfang in Richtung der Einengung 18 konisch verjüngend ausgebildet, während sie an ihrem inneren Umfang zylindrisch ausgebildet ist.In order now to prevent the closing
