Description

Die Erfindung betrifft eine Schließeinrichtung für eine Tür oder Klappe, insbesondere eines Fahrzeugs, vorzugsweise Kraftfahrzeugs, mit einem Zylinderschloss, das eine Zylinderbuchse und einen in der Zylinderbuchse drehbar gelagerten Zylinderkern aufweist, mit einem an der Tür oder Klappe befestigbaren oder befestigten Lagerbügel, der eine Aufnahme für das Zylinderschloss aufweist, und mit einer Schraube, die eine mechanische Verbindung der Zylinderbuchse mit einem Verkleidungselement der Schließeinrichtung für die Tür oder Klappe herstellt, wobei ein die Zylinderbuchse zumindest bereichsweise radial umgreifendes Bügelelement vorgesehen ist, das verschieblich gelagert an dem Lagerbügel angeordnet ist und das wenigstens ein Eingriffsmittel zum Eingreifen in eine Aussparung der Zylinderbuchse aufweist.
Schließeinrichtungen der eingangs genannten Art sind aus dem Stand der Technik, beispielsweise aus der DE 10 2004 012 456 A1 bekannt. Im Zuge der Weiterentwicklung von Kraftfahrzeugen findet auch eine Entwicklung von Maßnahmen zur Erhöhung der Diebstahl- oder Aufbruchsicherheit von Fahrzeugen statt. Neben elektronischen Einrichtungen, wie beispielsweise Wegfahrsperren, kommen dabei auch mechanische Einrichtungen zum Einsatz. Als mechanische Sicherheitseinrichtungen sind Schließeinrichtungen üblich, die ein in einer Tür oder einer Klappe des Fahrzeugs angeordnetes Zylinderschloss umfassen. Das Zylinderschloss weist als wesentliche Bauelemente eine insbesondere ortsfeste Zylinderbuchse auf, die an dem Lagerbügel befestigt ist und in welcher ein Zylinderkern drehbar gelagert ist. Infolge der Drehung des Zylinderkerns, die nur mit einem korrespondierenden, in den Kern eingeführten Schlüssel auslösbar ist, wird die Drehbewegung auf einen Schließmechanismus der Schließvorrichtung übertragen, wodurch letztendlich die Öffnung oder Schließung der Tür oder Klappe bewirkt wird. Das Zylinderschloss ist dabei üblicherweise in einem Lagerbügel gehalten, der im Inneren der Tür oder Klappe beziehungsweise an deren Innenseite befestigt ist.
Aus der DE 10 2004 012 456 A1 ist es außerdem bekannt, eine Schraube vorzusehen, die eine mechanische Verbindung der Zylinderbuchse mit einem Verkleidungsblech der Tür oder Klappe herstellt. Dazu ist die Schraube von außen durch das Verkleidungsblech und durch den Lagerbügel in einer Radialaussparung der Zylinderbuchse bereichsweise eingeführt. Die in der Radialausnehmung einliegende Spitze der Schraube sorgt dafür, dass sich die Zylinderbuchse bei gewaltsamer Zerstörung ihrer Befestigung an dem Verkleidungsblech verhakt und nicht herausgezogen werden kann.
Weiterhin ist es aus der Offenlegungsschrift DE 10 2012 112 520 A1 bereits bekannt, ein Bügelelement vorzusehen, das verschieblich an dem Lagerbügel gehalten ist und in Führungsnuten der Zylinderbuchse einerseits und des Lagerbügel andererseits verschieblich gelagert ist. Dabei ist vorgesehen, dass die Schraube in die Zylinderbuchse eingeschraubt ist.The invention relates to a closing device for a door or flap, in particular a vehicle, preferably a motor vehicle, with a cylinder lock having a cylinder liner and a cylinder core rotatably mounted in the cylinder core, with a fastened to the door or flap bearing bracket, a receptacle has for the cylinder lock, and with a screw which produces a mechanical connection of the cylinder liner with a cladding element of the closing device for the door or flap, wherein the cylinder liner at least partially radially embracing bracket member is provided which is slidably mounted on the bearing bracket and the has at least one engagement means for engaging in a recess of the cylinder liner.
Locking devices of the type mentioned are of the prior art, for example from the DE 10 2004 012 456 A1 known. In the course of the further development of motor vehicles, there is also the development of measures to increase theft or breakdown safety of vehicles. In addition to electronic devices, such as immobilizers, this also mechanical devices are used. As mechanical safety devices closing devices are common, which comprise a arranged in a door or a flap of the vehicle cylinder lock. The cylinder lock has as essential components on a particular stationary cylinder liner which is fixed to the bearing bracket and in which a cylinder core is rotatably mounted. Due to the rotation of the cylinder core, which can only be triggered with a corresponding key inserted into the core, the rotational movement is transmitted to a closing mechanism of the closing device, which ultimately causes the opening or closing of the door or flap. The cylinder lock is usually held in a bearing bracket, which is fixed inside the door or flap or on the inside.
From the DE 10 2004 012 456 A1 It is also known to provide a screw which establishes a mechanical connection of the cylinder liner with a trim panel of the door or flap. For this purpose, the screw is inserted from outside through the cladding sheet and through the bearing bracket in a radial recess of the cylinder liner partially. The in the Radial recess inset tip of the screw ensures that the cylinder liner in violent destruction of their attachment to the cladding sheet hooked and can not be pulled out.
Furthermore, it is from the published patent application DE 10 2012 112 520 A1 already known to provide a bracket member which is slidably held on the bearing bracket and is mounted on the other hand slidably mounted in guide grooves of the cylinder liner on the one hand and the bearing bracket. It is envisaged that the screw is screwed into the cylinder liner.

Aus der nicht vorveröffentlichten internationalen Anmeldung WO 2015/067562 A1 der Anmelderin ist weiterhin eine Schließeinrichtung nach dem Oberbegriff des Anspruchs 1 bekannt.From the non-prepublished international application WO 2015/067562 A1 the applicant is still a locking device according to the preamble of claim 1 known.

Aus der Patentschrift US 6,173,535 B1 ist weiterhin ein Türgriffsystem bekannt, das eine Torsionsstrebe aufweist, die einendig V-förmig ausgebildet ist, um eine Anordnung der Torsionsstrebe sowohl bei einer Montage an einer linken Fahrzeugseite als auch an einer rechten Fahrzeugseite zu ermöglichen. Dadurch kann auf das Bereitstellen unterschiedlicher Torsionsstreben für die verschiedenen Fahrzeugseiten verzichtet werden. Hierdurch ergibt sich eine Vereinheitlichung der Bauteile, die mit entsprechenden Vorteilen in Bezug auf die Herstellungskosten einher geht.
Zusätzlich zu der eigentlichen Befestigung der Zylinderbuchse in dem Lagerbügel ist somit die Schraube vorgesehen, die erst im Falle eines gewaltsamen Aufbrechens ihre Funktion erfüllt. Durch die Vielzahl der Einzelteile wird ein verhältnismäßig großer Bauraum beansprucht und es entstehen auch entsprechend hohe Herstellungs- und Montagekosten.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Schließeinrichtung zu schaffen, die kostengünstiger und bauraumsparend ausgebildet ist, ohne dabei an Sicherheit gegen ein Aufbrechen einzubüßen, und wobei eine Anpassung der Schließeinrichtung an unterschiedliche Rahmenbedingungen anpassbar ist. Die der Erfindung zugrunde liegende Aufgabe wird durch eine Schließeinrichtung mit den Merkmalen des Anspruchs 1 gelöst. Diese hat den Vorteil, dass sowohl für die Befestigung der Zylinderbuchse in dem Lagerbügel als auch für die Sicherung an dem Verkleidungselement nur eine einzige Schraube vorgesehen ist, die sowohl die Funktion der Befestigung als auch die Funktion der Sicherung übernimmt. Dadurch können Bauteilkosten gespart, die Montage zeitlich verkürzt und vereinfacht und Bauraum gespart werden, wobei die Sicherheit der Schließeinrichtung gegenüber gewaltsames Aufbrechen zumindest gleichbleibt. Vorzugsweise handelt es sich bei dem Verkleidungselement um ein Verkleidungsblech, besonders bevorzugt um ein Innenblech der Tür oder Klappe. Das Verkleidungselement stellt dabei einen Bestandteil der Schließeinrichtung dar. Dadurch, dass mindestens zwei Gewindebohrungen an dem Bügelelement vorgesehen sind, und entsprechend auch mindestens zwei Radialvertiefungen an der Zylinderbuchse, von denen jeweils eine einer der Gewindebohrungen zugeordnet ist, wird außerdem erreicht, dass unterschiedliche Positionen für die Schraube zur Befestigung der Zylinderbuchse zur Verfügung stehen. Diese hat insbesondere in Bezug auf das Verkleidungselement und daran vorgesehene/ausgebildete Dichtungen den Vorteil, dass die erfindungsgemäße Schließeinrichtung an Türen mit unterschiedlichen Verläufen der Dichtungen und/oder der Verkleidungselemente insgesamt verwendet werden kann, wobei durch die mindestens zwei unterschiedlichen Verschraubungsmöglichkeiten die Schraube in die jeweils besser geeigneten Position insbesondere in Bezug auf den Verlauf der Dichtung und/oder des Verkleidungselements angeordnet werden kann. Damit wird auch durch die erfindungsgemäße Lösung die Anzahl unterschiedlicher Bauteile, insbesondere unterschiedlich gestalteter Schließeinrichtungen für unterschiedliche Türen, insbesondere Fahrzeugtüren, verringert, wodurch auch Herstellungskosten reduziert werden.From the patent US 6,173,535 B1 Further, a door handle system is known, which has a torsion bar, which is formed in a single-ended V-shaped to allow an arrangement of the torsion bar both when mounted on a left side of the vehicle and on the right side of the vehicle. This eliminates the need to provide different torsion struts for the different sides of the vehicle. This results in a standardization of the components, which is associated with corresponding advantages in terms of manufacturing costs.
In addition to the actual attachment of the cylinder liner in the bearing bracket thus the screw is provided, which only fulfills its function in the event of a violent breakup. Due to the large number of items a relatively large amount of space is required and there are also correspondingly high manufacturing and assembly costs.
The invention is therefore an object of the invention to provide a locking device which is less expensive and space-saving, without sacrificing security against breakage, and wherein an adjustment of the locking device is adaptable to different conditions. The object underlying the invention is achieved by a locking device with the features of claim 1. This has the advantage that only a single screw is provided both for the attachment of the cylinder liner in the bearing bracket and for securing to the cladding element, which assumes both the function of attachment and the function of the fuse. As a result, component costs can be saved, the assembly shortened and simplified in time and space can be saved, the security of the locking device against violent breakage at least remains the same. Preferably, the cladding element is a cladding panel, more preferably an inner panel of the door or flap. The cladding element is doing a part of the locking device. Due to the fact that at least two threaded holes on the Ironing element are provided, and correspondingly also at least two radial recesses on the cylinder liner, one of which is associated with one of the threaded holes, is also achieved that different positions for the screw for fixing the cylinder liner are available. This has in particular in relation to the cladding element and provided thereon / seals formed the advantage that the closing device according to the invention can be used on doors with different gradients of the seals and / or the cladding elements in total, with at least two different Verschraubungsmöglichkeiten the screw into each better suitable position, in particular with respect to the course of the seal and / or the cladding element can be arranged. Thus, the number of different components, in particular differently shaped locking devices for different doors, in particular vehicle doors, is reduced by the inventive solution, which also reduces manufacturing costs.

Die erfindungsgemäße Schließeinrichtung zeichnet sich dadurch aus, dass die Schraube mit einer von mindestens zwei Gewindebohrungen des Bügelelementes zu dessen Verlagerung zusammenwirkt, wobei die Zylinderbuchse jeder der Gewindebohrungen zugeordnet beziehungsweise zuordenbar jeweils eine Radialvertiefung aufweist, die eine Druckfläche bildet, und wobei die Schraube an ihrem der Zylinderbuchse zugewandten Ende eine Druckspitze aufweist, die in die jeweilige Radialvertiefung eingebracht ist/wird und mit der Druckfläche zur axialen und radialen Abstützung der Schraube zusammenwirkt. Die Schließeinrichtung weist somit nur die eine Schraube zur Befestigung und Sicherung des Zylinderschlosses beziehungsweise der Zylinderbuchse auf. Die Schraube wird durch ein Gewinde des Bügelelementes beziehungsweise durch eine der Gewindebohrungen geführt. Durch eine Drehung der Schraube lässt sich diese bezüglich des Bügelelementes axial verschieben. Wird die Schraube derart weit in die gewählte Gewindebohrung eingeschraubt, dass ihre Druckspitze auf die Radialvertiefung beziehungsweise die Druckfläche der Radialvertiefung trifft, so wird eine Axialkraft erzeugt, die das Bügelelement mit dem die Gewindebohrung aufweisenden Abschnitt von der Zylinderbuchse wegdrängt. Dadurch lässt sich durch das Einschrauben der Schraube das Bügelelement spindelartig verschieben und insbesondere mit dem wenigstens einen Eingriffsmittel in Eingriff mit der Aussparung der Zylinderbuchse bringen, um diese in dem Lagerbügel zu befestigen. Vorzugsweise ist das wenigstens eine Eingriffsmittel auf der den Gewindebohrungen gegenüberliegenden Seite des Bügelelements, also in einem die Zylinderbuchse hintergreifenden Abschnitt des Bügelelements angeordnet. Das Bügelelement umgreift damit die Zylinderbuchse radial derart weit, dass es die Zylinderbuchse zumindest bereichsweise -aus Sicht der Gewindebohrung- hintergreift. Da die Schraube gleichzeitig die mechanische Verbindung zu dem Verkleidungselement herstellt, erfüllt die Schraube beide obengenannten Funktionen. Zur Befestigung stützt sich die Schraube an der Zylinderbuchse ab, um das Bügelelement zu verlagern, und steht gleichzeitig in mechanischer Verbindung mit dem Verkleidungselement, um das beschriebene Verhaken bei einem gewaltsamen Aufbrechen der Schließeinrichtung zu gewährleisten. Bei der Schraube handelt es sich also um die einzige Schraube zur Befestigung und Sicherung der Schließeinrichtung beziehungsweise des Zylinderschlosses. Dadurch, dass mehrere Gewindebohrungen und Radialvertiefungen vorgesehen sind, die das Einfügen der Schraube in unterschiedlichen Positionen erlaubt, kann die Schließeinrichtung vorteilhafterweise an unterschiedlichen Türen oder Klappen -wie oben bereits erwähnt- angeordnet und verwendet werden.The locking device according to the invention is characterized in that the screw cooperates with one of at least two threaded holes of the bracket member to its displacement, wherein the cylinder liner assigned to each of the threaded holes or assignable each having a radial recess which forms a pressure surface, and wherein the screw on her Cylinder socket facing the end has a pressure peak, which is introduced into the respective radial recess / and cooperates with the pressure surface for axial and radial support of the screw. The locking device thus has only one screw for fastening and securing the cylinder lock or the cylinder liner. The screw is guided by a thread of the bracket element or by one of the threaded holes. By a rotation of the screw can be moved axially with respect to the bracket element. If the screw is screwed so far into the selected threaded hole that its pressure peak strikes the radial recess or the pressure surface of the radial recess, then an axial force is generated, which pushes away the bracket element with the threaded bore having portion of the cylinder liner. As a result, by screwing in the screw, the bracket element can be moved in a spindle-like manner and, in particular, with the at least one engagement means, be brought into engagement with the recess of the cylinder liner in order to fasten it in the bearing bracket. Preferably, the at least one engagement means on the opposite side of the threaded holes of the bracket element, that is arranged in a cylinder bushing behind engaging portion of the bracket member. The strap member thus engages around the cylinder liner radially so far that it engages behind the cylinder liner at least partially - from the perspective of Gewindebohrung-. Since the screw at the same time makes mechanical connection to the cladding element, the screw fulfills both of the above functions. For attachment, the screw is supported on the cylinder liner to relocate the stirrup element and at the same time is in mechanical connection with the trim element to ensure the described entanglement in the event of a violent breakage of the closure device. The screw is thus the only screw for fastening and securing the locking device or the cylinder lock. Characterized in that a plurality of threaded holes and radial recesses are provided which allows the insertion of the screw in different positions, the locking device can advantageously be arranged and used on different doors or flaps -as already mentioned above.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das Bügelelement zumindest im Wesentlichen ringförmig ausgebildet ist und die Zylinderbuchse vollständig radial umgreift. Das Bügelelement umschließt somit die Zylinderbuchse vollständig und weist aufgrund der durchgehenden Ringform eine besonders hohe Stabilität gegen ein mechanisches Aufbrechen auf. Dadurch wird die Sicherheit gegen ein unbefugtes Öffnen der Tür oder Klappe weiter erhöht. Zweckmäßigerweise sind die Gewindebohrungen an einer Seite des Bügelelements nebeneinanderliegend ausgebildet. Insbesondere sind die Gewindebohrungen in Längserstreckung des Zylinders gesehen verteilt, insbesondere gleichmäßig verteilt angeordnet. Besonderes bevorzugt sind die Gewindeachsen der Gewindebohrungen dabei parallel zueinander ausgerichtet. Zweckmäßigerweise sind die Gewindeachsen parallel zur Verschieberichtung des Bügelelements ausgerichtet.According to a preferred embodiment of the invention it is provided that the bracket element is at least substantially annular and engages the cylinder liner completely radially. The bracket member thus encloses the cylinder liner completely and has due to the continuous ring shape a particularly high stability against mechanical breakage. As a result, the security against unauthorized opening of the door or flap is further increased. Conveniently, the threaded holes are formed side by side on one side of the bracket element. In particular, the threaded bores are distributed in the longitudinal extent of the cylinder, in particular evenly distributed. Particularly preferably, the threaded axes of the threaded holes are aligned parallel to each other. Conveniently, the threaded axes are aligned parallel to the direction of the ironing element.

Weiterhin ist bevorzugt vorgesehen, dass das Bügelelement auf der den Gewindebohrungen gegenüberliegenden Seite einen Quersteg als Eingriffsmittel aufweist. Der Quersteg verbindet zwei parallel und beabstandet zueinander angeordnete Schenkel des Bügelelements an ihren freien Enden miteinander, wodurch die geschlossene Ringform gebildet und die hohe Einbruchsicherheit gewährleistet wird. Dadurch, dass der Quersteg selbst das Eingriffsmittel bildet, sind keine weiteren Vorkehrungen an dem Bügelelement notwendig, wie beispielsweise radial nach innen vorstehende Eingriffsvorsprünge, sodass das Bügelelement besonders kostengünstig und einfach herstellbar ist. Selbstverständlich kann jedoch auch gemäß einer weiteren Ausführungsform vorgesehen sein, dass an dem Quersteg ein oder mehrere radial nach innen beziehungsweise in Richtung der Zylinderbuchse weisende Vorsprünge vorgesehen sind, die in entsprechende Aufnahmen eingreifen.Furthermore, it is preferably provided that the bracket element has on the opposite side of the threaded bores a crosspiece as engaging means. The crossbar connects two parallel and spaced apart legs of the bracket element at their free ends together, whereby the closed ring shape is formed and the high burglar resistance is ensured. The fact that the transverse web itself forms the engagement means, no further precautions to the bracket element are necessary, such as radially inwardly projecting engagement projections, so that the bracket element is particularly inexpensive and easy to produce. Of course, however, it can also be provided according to a further embodiment that one or more projections pointing radially inward or in the direction of the cylinder liner are provided on the transverse web, which engage in corresponding receptacles.

Bevorzugt ist vorgesehen, dass die Zylinderbuchse auf ihrer der Radialvertiefung gegenüberliegenden Seite die Aussparung zur Aufnahme des oder der Eingriffsmittel aufweist. Damit ist die Aussparung der Zylinderbuchse dem Eingriffsmittel des Bügelelementes zugeordnet, das auf der den Gewindebohrungen gegenüberliegenden Seite liegt. Zum einen wird hierdurch eine Fehlmontage verhindert, und zum anderen wird hierdurch das Einbringen des oder der Eingriffsmittel in die Aussparung durch das Abstützen der Schraube an der Druckfläche der Zylinderbuchse optimal ermöglicht.It is preferably provided that the cylinder liner on its side opposite the radial recess side has the recess for receiving the or the engagement means. Thus, the recess of the cylinder liner is associated with the engagement means of the bracket element, which lies on the opposite side of the threaded holes. On the one hand this prevents incorrect assembly, and on the other hand, the introduction of the or the engagement means in the recess by the support of the screw on the pressure surface of the cylinder liner is thereby optimally possible.

Vorzugsweise ist die Aussparung als Aufnahmenut in der Zylinderbuchse ausgebildet. Dadurch kann ein besonders breites Eingriffsmittel in die Aussparung eingreifen, wodurch der Formschluss vergrößert und die Sicherheit gegen Aufbrechen erhöht wird. Zweckmäßigerweise ist die Aufnahmenut zur Aufnahme des Querstegs ausgebildet, wobei sich die Aufnahmenut bevorzugt nur über einen beschränkten Umfangswinkel der Zylinderbuchse erstreckt. Zweckmäßigerweise sind die Schenkel, die von dem Quersteg zu dem die Gewindebohrung aufweisenden Abschnitt des Bügelelements führen, derart weit voneinander entfernt, dass die Zylinderbuchse zwischen ihnen durchgeführt werden kann. Durch das anschließende Verlagern des Schließbügels gelangt der Schließbügel in Eingriff mit der Ausnehmung und arretiert die Zylinderbuchse in axialer Richtung formschlüssig. Besonders bevorzugt ist vorgesehen, dass der Quersteg und/oder die Aufnahmenut jeweils wenigstens eine Einführfase aufweisen, die ein sicheres Einbringen des Bügelelementes in die Aussparung der Zylinderbuchse sowie eine automatische Zentrierung der Zylinderbuchse gewährleistet.Preferably, the recess is formed as a receiving groove in the cylinder liner. This allows a particularly wide engagement means engage in the recess, whereby the positive engagement is increased and the security against breakage is increased. Conveniently, the receiving groove for receiving the cross bar is formed, wherein the receiving groove preferably extends only over a limited circumferential angle of the cylinder liner. Conveniently, the legs, which lead from the crosspiece to the threaded bore portion of the bracket element, so far apart that the cylinder liner can be performed between them. By the subsequent displacement of the striker, the striker comes into engagement with the recess and locks the cylinder liner in the axial direction positively. It is particularly preferred that the transverse web and / or the receiving groove each have at least one Einführfase that ensures a safe insertion of the bracket element in the recess of the cylinder liner and an automatic centering of the cylinder liner.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Lagerbügel eine Schiebeführung zur zumindest im Wesentlichen nur radial bezüglich der Zylinderbuchse verlagerbaren Anordnung des Bügelelements aufweist. Durch die im Wesentlichen nur radiale Verschiebbarkeit des Bügelelements wird gewährleistet, dass das Bügelelement beziehungsweise die Zylinderbuchse axial mit nur geringem, vorzugsweise mit keinem Spiel beziehungsweise spielfrei an dem Lagerbügel gehalten ist. Die axiale Abstützung des Bügelelements erfolgt also an dem Lagerbügel selbst.According to an advantageous embodiment of the invention it is provided that the bearing bracket has a sliding guide for at least substantially only radially with respect to the cylinder liner displaceable arrangement of the bracket member. By essentially only radial displaceability of the bracket element ensures that the bracket member or the cylinder liner is held axially with only a small, preferably with no play or clearance on the bearing bracket. The axial support of the bracket element thus takes place on the bearing bracket itself.

Weiterhin ist bevorzugt vorgesehen, dass die Druckfläche der jeweiligen Radialvertiefung konisch ausgebildet ist, wobei die Druckspitze der Schraube komplementär zu der Druckfläche ausgebildet ist. Dadurch wird erreicht, dass eine flächige Auflage der Druckspitze in der Radialvertiefung beziehungsweise auf der Druckfläche zur vorteilhaften Kraftübertragung gewährleistet wird. Durch die konische Ausbildung wird außerdem eine automatische Zentrierung der Schraube beziehungsweise deren Druckspitze erreicht, wobei im eingeschraubten beziehungsweise in die Radialvertiefung eingebrachten Zustand über die Druckspitze der Schraube Kräfte auch radial bezüglich der Schraube auf das Bügelelement und andersherum übertragen werden können.Furthermore, it is preferably provided that the pressure surface of the respective radial recess is conical, wherein the pressure peak of the screw is formed complementary to the pressure surface. This ensures that a flat support of the pressure peak is ensured in the radial recess or on the pressure surface for advantageous power transmission. The conical training is also an automatic Centering of the screw or its pressure peak reached, wherein in the screwed or introduced into the radial recess state on the pressure peak of the screw forces can also be transmitted radially relative to the screw on the bracket element and vice versa.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Bügelelement einen ersten die Zylinderbuchse umgreifenden Abschnitt und einen zweiten, die Gewindebohrungen aufweisenden Abschnitt aufweist, wobei die beiden Abschnitte zumindest im Wesentlichen senkrecht zueinander ausgebildet sind. Hierdurch wird erreicht, dass insbesondere bei einer Ausbildung des Bügelelementes als Blechbiegeteil, der die Zylinderbuchse umgreifende Abschnitt verhältnismäßig flach ausgebildet sein kann, insbesondere flacher als der Durchmesser der Schraube, und dass die Gewindebohrungen auf einfache Art und Weise in den senkrecht dazu ausgerichteten Abschnitt einbringbar ist. Dadurch lässt sich auch die bereits erwähnte Ausbildung des Bügelelements als Blechbiegeteil auf einfache und kostengünstige Art und Weise realisieren.According to an advantageous embodiment of the invention, it is provided that the bracket element has a first cylinder bushing engaging portion and a second, the threaded holes having portion, wherein the two portions are at least substantially perpendicular to each other. This ensures that, in particular in a design of the bracket member as a sheet metal bending part, the cylinder sleeve encompassing portion may be formed relatively flat, in particular flatter than the diameter of the screw, and that the threaded holes in a simple manner in the perpendicular aligned portion can be introduced , As a result, the already mentioned embodiment of the bracket element can be realized as a sheet metal bent part in a simple and cost-effective manner.

Ferner ist bevorzugt vorgesehen, dass das Verkleidungselement eine Öffnung aufweist, durch welche die Schraube mit ihrem der Druckspitze gegenüberliegenden Ende hindurchgeführt ist. Dadurch wird auf einfache Art und Weise das Verhaken der Zylinderbuchse an dem Verkleidungselement bei einem gewaltsamen Aufbrechen der Schließeinrichtung gewährleistet. Vorzugsweise entspricht der Durchmesser der Erfindung nahezu dem Durchmesser eines Gewindeschafts der Schraube, um ein sicheres Verhaken zu gewährleisten.Further, it is preferably provided that the cladding element has an opening through which the screw is passed with its opposite end of the pressure tip. As a result, the hooking of the cylinder liner to the cladding element is ensured in the event of a violent break-up of the closing device in a simple manner. Preferably, the diameter of the invention almost corresponds to the diameter of a threaded shaft of the screw to ensure a secure hooking.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die Schraube einen Schraubenkopf aufweist, dessen Durchmesser größer als der Durchmesser der Öffnung des Verkleidungselementes ist, wobei der Schraubenkopf auf der dem Bügelelement gegenüberliegenden Seite des Verkleidungselements liegt, sodass vorteilhafterweise durch den Schraubenkopf eine zusätzliche formschlüssige Sicherung gegen ein unbefugtes Aufbrechen der Schließeinrichtung gewährleistet wird.According to a preferred embodiment of the invention it is provided that the screw has a screw head whose diameter is greater than the diameter of the opening of the cladding element, wherein the screw head is located on the opposite side of the cleat element of the cladding element, so advantageously by the screw head an additional positive locking is ensured against unauthorized breaking the locking device.

Im Folgenden soll die Erfindung anhand eines Ausführungsbeispiels näher erläutert werden. Dazu zeigen:

Figur 1 zeigt eine ausschnittsweise dargestellte Tür 1 eines nicht näher dargestellten Kraftfahrzeugs, die eine Schließeinrichtung 2 aufweist, in einer Schnittdarstellung. An der Tür 1 ist ein Lagerbügel 3 der Schließeinrichtung 2 fest angeordnet, der auch einen betätigbaren Türgriff 4 trägt. Der Lagerbügel 3 weist weiterhin eine Aufnahme 5 auf, in welcher ein Zylinderschloss 6 angeordnet ist. FIG. 1 shows a fragmentary door 1 of a motor vehicle, not shown, which has a closing device 2, in a sectional view. On the door 1, a bearing bracket 3 of the locking device 2 is fixed, which also carries an actuable door handle 4. The bearing bracket 3 further has a receptacle 5, in which a cylinder lock 6 is arranged.

Das Zylinderschloss 6 weist eine Zylinderbuchse 7 sowie einen in der Zylinderbuchse drehbar gelagert angeordneten Zylinderkern 8 auf. Die Drehung des Zylinderkerns 8 ist nur mit einem korrespondierenden, in den Kern eingeführten Schlüssel auslösbar. Die grundsätzliche Ausbildung eines Zylinderschlosses ist aus dem Stand der Technik bekannt und soll daher hier nicht näher erläutert werden. Die Zylinderbuchse 7 ist axial in die Aufnahme 5 eingeschoben und zumindest radial formschlüssig durch die Aufnahme 5 gehalten.The cylinder lock 6 has a cylinder bushing 7 and a cylinder core 8 which is rotatably mounted in the cylinder bushing. The rotation of the cylinder core 8 can only be triggered with a corresponding key inserted into the core. The basic design of a cylinder lock is known from the prior art and will therefore not be explained in detail here. The cylinder liner 7 is inserted axially into the receptacle 5 and held at least radially positive fit by the receptacle 5.

Dem Zylinderschloss 6 ist weiterhin ein Bügelelement 9 zugeordnet, das zur axialen Fixierung der Zylinderbuchse 7 und damit des Zylinderschlosses 6 in der Aufnahme 5 beziehungsweise an dem Lagerbügel 3 dient. Weiterhin weist die Schließeinrichtung 2 eine Schraube 10 auf, die mit dem Bügelelement 9, wie untenstehend beschrieben wird, zusammenwirkt. Die Schraube 10 kann in zwei unterschiedlichen Positionen P1 und P2 angeordnet werden, wobei eine erste Position P1 durch durchgezogene Linien und eine zweite Position P2 durch gestrichelte Linien in Figur 1 gezeigt sind.The cylinder lock 6 is further associated with a bracket member 9, which serves for the axial fixation of the cylinder liner 7 and thus of the cylinder lock 6 in the receptacle 5 and on the bearing bracket 3. Furthermore, the closure device 2 has a screw 10, which cooperates with the bracket element 9, as described below. The screw 10 can be arranged in two different positions P1 and P2, wherein a first position P1 by solid lines and a second position P2 by dashed lines in FIG. 1 are shown.

Figur 2 zeigt hierzu eine vergrößerte Detailansicht der Schließeinrichtung 2 in einer weiteren Schnittdarstellung. Dabei zeigt Figur 2 eine Detailansicht der ersten Position P1 der Schraube 10, wobei die Ausbildung der Schließeinrichtung 2 bezogen auf die Position P1 in der Position P2 wiederholt wird, sodass die folgende Beschreibung auch für die Ausbildung der Schließeinrichtung 2 im Bereich der Position P2 gilt. Die Schraube 10 weist einendig einen Schraubenkopf 11 auf, an den sich ein Gewindeschaft 12 anschließt, der anderendig in einer Druckspitze 13 endet. Der Gewindeschaft 12 weist ein Außengewinde 14 auf, das mit einem Innengewinde 15 einer Gewindebohrung 16 des Bügelelementes 9 zusammenwirkt. Die Druckspitze 13 weist eine konische Kontur auf und ist dazu ausgebildet, mit einer Druckfläche 17, die von einer Radialvertiefung 18 der Zylinderbuchse 7 gebildet wird, zusammenzuwirken. Die Druckfläche 17 weist dabei eine zu der Druckspitze 13 komplementäre Konizität auf, sodass die Druckspitze 13 flächig an der Druckfläche 17 aufliegt, sodass sowohl axial als auch radial - in Bezug auf die Schraube 10 - Kräfte übertragen werden können. Um die Schraube 10 oder eine andere Schraube 10 an der Position P2 anzuordnen, weist die Schließeinrichtung 2 beabstandet zu der Gewindebohrung 16 eine weitere Gewindebohrung 16 in dem Bügelelement 9 auf, die in Längsrichtung der Zylinderbuchse 7 versetzt zu der ersten Gewindebohrung 16 ausgebildet ist. Der weiteren Gewindebohrung 16 ist eine weitere Radialvertiefung 18 in der Zylinderbuchse 7 zugeordnet, die, wie zuvor beschriebenen, mit der Druckspitze 13 der Schraube 10 zusammenwirkt. FIG. 2 shows an enlarged detail view of the locking device 2 in a further sectional view. It shows FIG. 2 a detailed view of the first position P1 of the screw 10, wherein the formation of the locking device 2 is repeated relative to the position P1 in the position P2, so that the following description also applies to the formation of the locking device 2 in the region of the position P2. The screw 10 has at one end a screw head 11, to which a threaded shaft 12 connects, the other end in a Pressure peak 13 ends. The threaded shaft 12 has an external thread 14 which cooperates with an internal thread 15 of a threaded bore 16 of the bracket element 9. The pressure peak 13 has a conical contour and is designed to cooperate with a pressure surface 17, which is formed by a radial recess 18 of the cylinder liner 7. The pressure surface 17 has a conicity complementary to the pressure peak 13, so that the pressure peak 13 rests flat against the pressure surface 17, so that both axially and radially - with respect to the screw 10 - forces can be transmitted. To arrange the screw 10 or another screw 10 at the position P2, the closing device 2 at a distance from the threaded bore 16 has a further threaded bore 16 in the bracket element 9 which is offset in the longitudinal direction of the cylinder sleeve 7 to the first threaded bore 16. The further threaded bore 16 is associated with a further radial recess 18 in the cylinder liner 7, which, as described above, cooperates with the pressure peak 13 of the screw 10.

Figur 3 zeigt das Zylinderschloss 6 zusammen mit dem Bügelelement 9 und der Schraube 10 in einer perspektivischen Darstellung. Hierbei ist zu erkennen, dass das Bügelelement 9 einen ersten Abschnitt 19 aufweist, welcher die Gewindebohrungen 16 für die Schraube 10 umfasst, und einen zweiten Abschnitt 20, der die Zylinderbuchse 7 des Zylinderschlosses 6 radial umgreift. FIG. 3 shows the cylinder lock 6 together with the bracket member 9 and the screw 10 in a perspective view. It can be seen that the bracket member 9 has a first portion 19 which includes the threaded holes 16 for the screw 10, and a second portion 20 which radially surrounds the cylinder liner 7 of the cylinder lock 6.

Figur 4 zeigt hierzu das Bügelelement 9 zusammen mit der Schraube 10 in einer weiteren perspektivischen Darstellung, aus welcher ersichtlich wird, dass das Bügelelement 9 im Wesentlichen ringförmig mit einer rechteckförmigen Kontur ausgebildet ist. Durch diese Ringform weist das Bügelelement 9 ausgehend von dem Abschnitt 19 in dem Abschnitt 20 zwei parallel zueinander angeordnete und voneinander beabstandete Schenkel 20' und 20" auf, die an ihren freien Enden durch einen Quersteg 20''' miteinander verbunden sind. Das Bügelelement 9 ist einstückig ausgebildet und besonders bevorzugt als Blechbiegeteil hergestellt. Der erste Abschnitt 19 ist dabei im Wesentlichen senkrecht zu dem zweiten Abschnitt 20 ausgerichtet, wobei sich die Gewindebohrungen 16, durch welche die Schraube 10 mit ihrem Gewindeschaft 12 geführt ist, auf Höhe des Querstegs 20''' befindet, sodass die Drehachse der Schraube 10 in der Ebene des Abschnitts 20 liegt, wobei die Druckspitze 13 der Schraube 10 auf den Querschnitt 20''' weisend ausgerichtet ist. Die weitere Gewindebohrung 16 ist auf einer Höhe versetzt zu dem Quersteg 20''' angeordnet. Gemäß einem alternativen, hier nicht dargestellten Ausführungsbeispiel ist vorgesehen, dass die beiden Gewindebohrungen 16 beide gleich beabstandet zu der Höhe des Querstegs 20''' in dem Abschnitt 19 ausgebildet sind. Besonders bevorzugt ist vorgesehen, dass das Bügelelement 9 zwei der Querstege 20''' aufweist, die jeweils auf Höhe einer der Gewindebohrungen 16 liegen. Die beiden Schenkel 20' und 20" sowie der Quersteg 20''' und der Abschnitt 19 liegen eine Öffnung des Bügelelementes bildend jeweils derart weit beabstandet voneinander, dass die Zylinderbuchse 7, wie durch einen Pfeil 21 in Figur 3 angedeutet, durch die Öffnung des Bügelelements 9 hindurch beziehungsweise hineinschiebbar ist. FIG. 4 shows the bracket member 9 together with the screw 10 in a further perspective view, from which it will be apparent that the bracket member 9 is formed substantially annular with a rectangular contour. As a result of this ring shape, the bracket element 9, starting from the section 19 in the section 20, has two legs 20 'and 20 "arranged parallel to one another and spaced apart from each other, which are connected to one another at their free ends by a transverse web 20''' The first portion 19 is aligned substantially perpendicular to the second portion 20, wherein the threaded holes 16, through which the screw 10 is guided with its threaded shank 12, at the level of the crosspiece 20 '. is located so that the axis of rotation of the screw 10 is in the plane of the section 20, the pressure peak 13 of the screw 10 being aligned with the cross-section 20 '''The further threaded bore 16 is offset at a height to the transverse web 20'. According to an alternative embodiment, not shown here, it is provided that the two taps ments 16 both equally spaced from the height of the transverse web 20 '''in the section 19 are formed. It is particularly preferred that the bracket element 9 two of the transverse webs 20 ''', which are each at the level of one of the threaded bores 16. The two legs 20 'and 20 "and the crossbar 20''' and the portion 19 are forming an opening of the bracket element respectively spaced so far from each other that the cylinder liner 7, as indicated by an arrow 21 in FIG. 3 indicated by the opening of the bracket member 9 through or hineinschiebbar.

Die Zylinderbuchse 7 weist auf ihrer der Radialvertiefung 18 gegenüberliegenden Seite eine Ausnehmung 22 in Form einer Aufnahmenut 23 auf, wie am besten in Figur 1 ersichtlich. Die Aufnahmenut 23 weist eine Höhe beziehungsweise lichte Weite auf, die im Wesentlichen der Höhe des Querstegs 20''' entspricht, sodass dieser in die Aufnahmenut 23 vorzugsweise spielfrei einschiebbar ist, wie in Figuren 1 und 3 dargestellt. Die Aufnahmenut 23 erstreckt sich dabei bevorzugt lediglich über die Rückseite beziehungsweise die der Radialvertiefung 18 gegenüberliegenden Seite der Zylinderbuchse 7.The cylinder liner 7 has on its radial recess 18 opposite side of a recess 22 in the form of a receiving groove 23, as best in FIG. 1 seen. The receiving groove 23 has a height or clear width, which substantially corresponds to the height of the transverse web 20 ''', so that it is preferably inserted into the receiving groove 23 without play, as in FIGS. 1 and 3 shown. The receiving groove 23 preferably extends only over the rear side or the radial recess 18 opposite side of the cylinder liner. 7

Anhand von Figur 5 soll nunmehr die Befestigung des Zylinderschlosses 6 an dem Lagerbügel 3 mittels des Bügelelements 9 erläutert werden. Figur 5 zeigt hierbei eine Draufsicht auf die Baugruppe aus Zylinderschloss 6 und Bügelelement 9 sowie Schraube 10 gemäß Figur 3 im fertig montierten Zustand. Zunächst wird das Bügelelement 9 in dem Lagerbügel 3 positioniert. Dazu weist der Lagerbügel 3 eine Schiebeführung 24 auf, durch welche das Bügelelement 9 in der Ebene des Abschnitts 20 radial bezüglich der Zylinderbuchse 7 verschiebbar gelagert ist. Anschließend wird das Zylinderschloss 6 in die Aufnahme 5 und durch die Öffnung des vormontierten Bügelelements 9 eingeschoben, gemäß Pfeil 21. Anschließend wird die Schraube 10 zugeführt, und zwar derart, dass sie in Richtung des Querstegs 20''' in eine der Gewindebohrungen 16 eingeschraubt wird. Dabei wird in Abhängigkeit von den Bauraumbedingungen entschieden, in welche der Gewindebohrungen 16 die Schraube 10 eingeschraubt werden soll. Figur 1 zeigt hierzu in dem Ausführungsbeispiel ein erstes Verkleidungselement und gestrichelt als Alternative ein zweites Verkleidungselement 26'. Die Verkleidungselemente 26 und 26' unterscheiden sich in ihrer Formgebung und sind beispielsweise an eine Karosserie des die Tür 1 aufweisenden Kraftfahrzeugs optimal in Bezug auf eine Dichtwirkung angepasst. Je nachdem, welches der Verkleidungselemente 26, 26' vorgesehen ist, wird die Schraube 10 in die Position P1 oder die Position P2 geführt. Je nach Ausführungsform der Verkleidungselemente 26, 26' kann erforderlich sein, dass in Abhängigkeit davon, in welche Position die Schraube 10 angeordnet werden soll, ein Schraubenschaft der Schraube 10 unterschiedlich lang ausgebildet sein muss, damit der Schraubenkopf 11 der Schraube 10 das jeweilige Verkleidungselement 26, 26' hintergreifen kann. Sobald die Druckspitze 13 mit der Rückfläche 17 in Anlagekontakt gerät, wird eine Axialkraft ausgeübt, durch welche das Bügelelement 9 in Richtung des Schraubenkopfes 11 auf dem Gewindeschaft 12 spindelartig gezogen wird. Dadurch wird der Quersteg 20''' in die Aufnahmenut 23 der Zylinderbuchse 7 eingeschoben. Vorzugsweise wird der Quersteg 20''' bis zum Anschlag in die Aufnahmenut 23 eingezogen, sodass er im Wesentlichen vollständig die Aufnahmenut 23 ausfüllt. Dadurch wird ein Formschluss zwischen Bügelelement 9 und Zylinderbuchse 7 in axialer Richtung - in Bezug auf die Zylinderbuchse 7 gesehen - gebildet, der ein einfaches Herausziehen des Zylinderschlosses 6 aus der Aufnahme 5 des Lagerbügels 3 sicher verhindert. Hierdurch wird das Zylinderschloss 6 auf einfache Art und Weise an dem Lagerbügel 3 beziehungsweise der Tür 1 befestigt.
Wie aus Figuren 1 und 2 ersichtlich, ist weiterhin vorgesehen, dass der Gewindeschaft 12 der Schraube 10 durch eine Öffnung 25 des Verkleidungselements 26 der Tür 1, das insbesondere als Innenblech ausgebildet ist, hindurchgeführt ist, sodass der Schraubenkopf 11 außerhalb des Verkleidungselements 26 liegt, während die übrige Schließeinrichtung 2 innerhalb des Verkleidungselements 26 angeordnet ist. Der Schraubenkopf 11 weist dabei einen Außendurchmesser auf, der größer ist als der der Öffnung 25. Bei der Montage wird die Schraube 10 daher von außen durch die Öffnung 25 des Verkleidungselements 26 der Gewindebohrung 16 des Bügelelements 9 zugeführt. Die Schließeinrichtung 2 ist dabei derart ausgebildet, dass der Schraubenkopf 11 auch dann außerhalb des Verkleidungselements 26 liegt, wenn die Schraube 10 maximal in die Gewindebohrung 16 eingeschraubt wurde. Dadurch wird zusätzlich zu der Befestigung des Zylinderschlosses 6 an dem Lagerbügel 3 eine weitere Sicherung gegen unbefugtes Öffnen der Tür gewährleistet. Würde das Zylinderschloss 6 unter Gewaltaufbringung aus der Aufnahme 5 herausgezogen werden, so würde aufgrund der radialen Kraftübertragung auf die Schraube 10 durch die konische Druckfläche 17 erreicht, dass durch die mechanische Verbindung mit dem Verkleidungselement 26 die Zylinderbuchse 7 beziehungsweise das Zylinderschloss 6 sich an dem Verkleidungselement 26 verhakt. Dadurch wird auch dann, wenn die Befestigung des Zylinderschlosses 6 aufgebrochen wurde, ein einfaches Herausziehen des Zylinderschlosses 6 aus dem Lagerbügel 3 verhindert.
Die Schraube 10 erfüllt somit zwei Funktionen gleichzeitig, zum einen das Befestigen des Zylinderschlosses 6 und zum anderen das Sichern des Zylinderschlosses 6 bei einem Aufbrechen der Schließeinrichtung 2, wobei dadurch, dass die Schraube 10 in unterschiedlichen Positionen P1, P2 verwendet werden kann, eine Anpassung der Schließeinrichtung 2 an unterschiedliche Rahmenbedingungen, insbesondere an unterschiedliche Bauraumbedingungen/-verhältnisse anpassbar ist, wie mit Bezug auf die unterschiedlich ausgebildeten Verkleidungselemente 26, 26' beschrieben.Based on FIG. 5 will now be explained the attachment of the cylinder lock 6 on the bearing bracket 3 by means of the bracket element 9. FIG. 5 shows a plan view of the assembly of cylinder lock 6 and bracket member 9 and screw 10 according to FIG. 3 in the assembled state. First, the bracket member 9 is positioned in the bearing bracket 3. For this purpose, the bearing bracket 3 on a sliding guide 24, by which the bracket member 9 is mounted radially in the plane of the portion 20 radially relative to the cylinder liner 7 slidably. Subsequently, the cylinder lock 6 is inserted into the receptacle 5 and through the opening of the preassembled bracket element 9, as indicated by arrow 21. Subsequently, the screw 10 is supplied, in such a way that it in the direction of the crosspiece 20 '''screwed into one of the threaded bores 16 becomes. It is decided depending on the installation space conditions, in which of the threaded holes 16, the screw 10 is to be screwed. FIG. 1 shows in the embodiment, a first cladding element and dashed as an alternative a second cladding element 26 '. The cladding elements 26 and 26 'differ in their shape and are optimally adapted, for example, to a body of the motor vehicle having the door 1 with respect to a sealing effect. Depending on which of the cladding elements 26, 26 'is provided, the screw 10 is guided to the position P1 or the position P2. Depending on the embodiment of the cladding elements 26, 26 'may be required that depending on the position in which the screw 10 is to be arranged, a screw shank of the screw 10 must be designed to be different lengths, so that the screw head 11 of the screw 10, the respective cladding element 26th , 26 'can reach behind. As soon as the pressure peak 13 comes into contact with the rear surface 17, an axial force is exerted, by which the bracket member 9 is pulled in the direction of the screw head 11 on the threaded shaft 12 in a spindle-like manner. As a result, the transverse web 20 '''is inserted into the receiving groove 23 of the cylinder liner 7. Preferably, the crossbar 20 '''retracted into the receiving groove 23 until it stops, so that it substantially completely fills the receiving groove 23. As a result, a positive connection between the bracket element 9 and cylinder liner 7 in the axial direction - as seen in relation to the cylinder liner 7 - formed, which reliably prevents easy removal of the cylinder lock 6 from the receptacle 5 of the bearing bracket 3. As a result, the cylinder lock 6 is fastened in a simple manner to the bearing bracket 3 or the door 1.
How out Figures 1 and 2 can be seen, it is further provided that the threaded shaft 12 of the screw 10 is passed through an opening 25 of the lining element 26 of the door 1, which is in particular designed as an inner plate, so that the screw head 11 is outside of the cladding element 26, while the rest of the closing device 2 inside the cladding element 26 is arranged. The screw head 11 in this case has an outer diameter which is larger than that of the opening 25. During assembly, the screw 10 is therefore supplied from the outside through the opening 25 of the lining element 26 of the threaded bore 16 of the bracket element 9. The closing device 2 is designed such that the screw head 11 is also outside of the cladding element 26 when the screw 10 has been screwed into the maximum threaded bore 16. As a result, in addition to the fastening of the cylinder lock 6 on the bearing bracket 3, a further safeguard against unauthorized opening of the door is ensured. If the cylinder lock 6 are pulled out of the receptacle 5 by force application, the radial force transmission to the screw 10 would be achieved by the conical pressure surface 17, that through the mechanical connection with the lining element 26, the cylinder liner 7 or the cylinder lock 6 on the cladding element 26 hooked. As a result, even when the attachment of the cylinder lock 6 has been broken, a simple extraction of the cylinder lock 6 from the bearing bracket 3 is prevented.
The screw 10 thus fulfills two functions simultaneously, on the one hand the fastening of the cylinder lock 6 and on the other the securing of the cylinder lock 6 at a break of the closing device 2, wherein the fact that the screw 10 can be used in different positions P1, P2, an adaptation the closing device 2 to different conditions, in particular to different installation space conditions / conditions is adaptable, as described with reference to the differently shaped cladding elements 26, 26 '.

Während sich das vorliegende Ausführungsbeispiel auf eine Fahrzeugtür bezieht, kann gemäß einem anderem Ausführungsbeispiel vorgesehen sein, dass die beschriebene Schließeinrichtung 2 auch an einer Fahrzeugklappe, wie beispielsweise einer Kofferraumklappe oder Dergleichen, angeordnet ist.While the present embodiment relates to a vehicle door, according to another embodiment, it may be provided that the described closure device 2 is also arranged on a vehicle flap, such as a boot lid or the like.
