SCHLIESSVORRICHTUNG  CLOSING
Beschreibung description
Die Erfindung betrifft eine Schließvorrichtung, insbesondere eines Kraftfahrzeuges, mit einem Schlüssel und einem Schließzylinder, mit einem in einem Zylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal aufweist, in den der Schlüssel einbringbar ist, federbelastete Zuhalteelemente, die beim Einstecken des Schlüssels in den Schlüsselkanal radial zur Zylinderachse des Schließzylinders verschiebbar gelagert sind, mehreren am Schlüssel vorgesehenen Außenflächen, die Steuerbahnen aufweisen, die beim Einführen des Schlüssels auf die Zuhalteelemente wirken. The invention relates to a locking device, in particular a motor vehicle, with a key and a lock cylinder, with a rotatably mounted in a cylinder housing cylinder core, which has a keyway into which the key is inserted, spring-loaded tumblers, the radial when inserting the key into the keyway are slidably mounted to the cylinder axis of the lock cylinder, a plurality of provided on the key outer surfaces having control tracks, which act on insertion of the key on the tumblers.
In der DE 10 2007 014 900 A1 ist eine Schließvorrichtung der oben genannten Art offenbart, wobei der Schlüssel sowohl an seinen beiden Schmalseiten als auch an seinen zwei Breitseiten jeweils mit einer Steuerbahn ausgeführt ist. Die genannten Steuerbahnen wirken auf federbelastete Zuhalteelemente, die im Schließzylinder angeordnet sind. Es hat sich gezeigt, dass derartige Zuhalteelemente sich insbesondere bei Kraftfahrzeugen bewährt haben. Um ein Kraftfahrzeug zu entwenden, bemühen sich unberechtigte Personen mittels Einbruchswerkzeuge, z. B. durch ein sogenanntes„Picking-Systems", die Zuhalteelemente im Schlüsselkanal auf dem Querschnitt des Zylinderkerns zu sortieren, wodurch die Zuhalteelemente den Zylinderkern zur Drehung freigeben. In DE 10 2007 014 900 A1 discloses a closing device of the above type is disclosed, wherein the key is executed both at its two narrow sides and at its two broad sides each with a control track. The said control tracks act on spring-loaded locking elements, which are arranged in the lock cylinder. It has been shown that such Locking elements have proven particularly in motor vehicles. In order to steal a motor vehicle, unauthorized persons strive by means of burglary tools, for. B. by a so-called "picking system" to sort the tumblers in the keyway on the cross section of the cylinder core, whereby the tumblers release the cylinder core for rotation.
Es hat sich ergeben, dass in einigen Anwendungsfällen geringere Bauräume für derartige Schließvorrichtungen notwendig sind, wobei gleichzeitig eine hohe Aufbruchsicherheit der Schließvorrichtung zu gewährleisten ist. It has been found that in some applications smaller installation spaces are necessary for such closing devices, at the same time ensuring a high resistance to breakage of the closing device.
Zur Lösung dieser Aufgabe wird eine Schließvorrichtung mit allen technischen Merkmalen des Anspruches 1 vorgeschlagen. In den abhängigen Patentansprüchen sind mögliche Ausführungsformen vorgeschlagen. To solve this problem, a locking device with all the technical features of claim 1 is proposed. In the dependent claims possible embodiments are proposed.
Erfindungsgemäß weisen die Außenflächen des Schlüssels zwei Schmalseiten und zwei Breitseiten auf, wobei jede Breitseite mit einer ersten Steuerbahn ausgeführt ist, die erste Schmalseite eine zweite Steuerbahn aufweist, und die zweite der ersten Schmalseite gegenüberliegende Schmalseite steuerbahnfrei ausgebildet ist. Einer der wesentlichen Vorteile dieser erfindungsgemäßen Schließvorrichtung ist, dass aufgrund der steuerbahnfrei ausgeführten zweiten Schmalseite des Schlüssels zum einen der Schließzylinder sowie der Zylinderkern mit dem Schlüsselkanal kleiner und kompakter ausgeführt werden kann. Des Weiteren wird ein kompakterer Schlüssel geschaffen, der einen geringeren Bauraum im Schließzylinder benötigt. According to the invention, the outer surfaces of the key have two narrow sides and two broad sides, wherein each broad side is embodied with a first control track, the first narrow side has a second control track, and the second narrow side opposite the first narrow side is free of control tracks. One of the main advantages of this locking device according to the invention is that due to the tax-free executed second narrow side of the key on the one hand, the lock cylinder and the cylinder core with the key channel can be made smaller and more compact. Furthermore, a more compact key is created, which requires less space in the lock cylinder.
Ebenfalls kann erfindungsgemäß vorgesehen sein, dass das Zuhalteelement mit mindestens einem Vorsprung ausgeführt ist, das bei nicht eingeführten Schlüssel in den Schlüsselkanal ragt, wobei der Vorsprung durch die erste oder die zweite Steuerbahn beim Einführen des Schlüssels aus den Schlüsselkanal bewegbar ist, wobei insbesondere das Zuhalteelement an seiner der zweiten Schmalseite zugewandten Seite vorsprungfrei ausgeführt ist, insbesondere der ebenen, flächigen Ausgestaltung der zweiten Schmalseite geometrisch angepasst ist. Die Steuerbahnen dienen hierbei als Codebahn, wobei die Codebahn mit einer derartigen Profilierung ausgeführt ist, die mit den Zuhalteelementen des Schließzylinders entsprechend korrespondieren, das bedeutet, dass lediglich der Schlüssel mit der entsprechend „richtigen" Codebahn bzw. Codebahnen eine entsprechende Verschiebung der Zuhalteelemente aus dem Schlüsselkanal bewirkt, um beim eingesteckten Schlüssel eine Bewegung des Zylinderkerns innerhalb des Zylindergehäuses zu bewirken. It can also be provided according to the invention that the locking element is designed with at least one projection which projects into the keyway with not inserted key, wherein the projection is movable by the first or the second control path during insertion of the key from the keyway, wherein in particular the locking element on its side facing the second narrow side is designed without projections, in particular the flat, planar configuration of the second narrow side is geometrically adjusted. The control tracks serve as a code track, wherein the code track is designed with such a profiling that correspond with the locking elements of the lock cylinder accordingly, that means that only the key effected with the corresponding "correct" code track or code tracks a corresponding displacement of the tumblers from the keyway to cause the plugged key movement of the cylinder core within the cylinder housing.
Vorteilhafterweise bildet die zweite Schmalseite in ihrer gesamten Erstreckung des Schlüssels eine ebene Fläche. Aufgrund der flächigen zweiten Schmalseite, die an einer der vier Wandungen des Schlüsselkanals anliegt, wird auf einfache Weise ein Kippeln des Schlüssels verringert, wodurch ein weitaus geringerer Verschleiß des Schließzylinders und der Zuhalteelemente bei einem wiederholten Einführen und Betätigen des Schließzylinders mit dem Schlüssel erfolgt. Advantageously, the second narrow side forms in its entire extension of the key a flat surface. Due to the flat second narrow side, which rests against one of the four walls of the keyway, a tilting of the key is reduced in a simple manner, whereby a much lesser wear of the lock cylinder and the locking elements in a repeated insertion and actuation of the lock cylinder is done with the key.
Eine mögliche Ausführungsform der Erfindung ist, dass die erste und/oder die zweite Steuerbahn als Steuernut ausgebildet ist, wobei insbesondere die Steuernut eine im Wesentlichen gleich bleibende Bahnbreite aufweist. Alternativ oder zusätzlich ist es ebenfalls denkbar, dass die erste Steuerbahn eine Steuernut ist und die zweite Steuerbahn eine Steuerrippe ist. Die Steuernut ist hierbei konkav ausgebildet, wobei die Steuerrippe konvex an der Außenfläche des Schlüssels ausgeführt ist und ihre Außenfläche vom Schlüssel überragt. A possible embodiment of the invention is that the first and / or the second control track is formed as a control groove, wherein in particular the control groove has a substantially constant track width. Alternatively or additionally, it is also conceivable that the first control track is a control groove and the second control track is a control rib. The control groove is in this case concave, wherein the control rib is convex on the outer surface of the key and its outer surface surmounted by the key.
Vorteilhafterweise ist der Schlüssel nur in einer Position in dem Zylinderkern einsteckbar, so dass es sich hier um keinen Wendeschlüssel handelt. Zweckmäßigerweise ist der Schlüssel ein massives Bauteil, bei dem die Steuerbahnen eingefräst sind. Durch die Maßnahme einer Steuerbahnfreien Schmalseite kann die Schlüsselhöhe weiter reduziert werden. Durch die resultierende mögliche Verkleinerung des Schlüsselkanals wird der Schließzylinder auch aufbruchsicherer, da mit jeder Verkleinerung ebenfalls ein potentielles Aufbruchswerkzeug kleiner werden muss, um noch in den Schüsselkanal eingeführt zu werden und auch die maximale ausübbare Kraft verringert wird. Advantageously, the key can only be inserted in one position in the cylinder core, so that this is not a reversible key. Conveniently, the key is a solid component in which the control tracks are milled. By the measure of a tax-free narrow side, the key height can be further reduced. Due to the resulting possible reduction of the key channel of the lock cylinder is also safe from breakage, as with each reduction also a potential breaking tool must be smaller in order to be introduced into the bowl channel and also the maximum exercisable force is reduced.
Weitere Maßnahmen und Vorteile sowie technische Merkmale der Erfindung ergeben sich aus den Ansprüchen, der nachfolgenden Beschreibung und den Zeichnungen. In den nachstehenden Figuren ist die erfindungsgemäße Schließvorrichtung in einem Ausführungsbeispiel detailliert dargestellt. Es zeigen: Fig. 1 eine perspektivische Ansicht des Schaftes des Schlüssels der erfindungsgemäßen Vorrichtung, Further measures and advantages and technical features of the invention will become apparent from the claims, the following description and the drawings. In the following figures, the closing device according to the invention is shown in detail in one embodiment. Show it: 1 is a perspective view of the shaft of the key of the device according to the invention,

Die Figuren 1 bis 4 zeigen rein schematisch eine Schließvorrichtung eines Kraftfahrzeuges mit einem Schlüssel 10 und einem Schließzylinder 30, der in einer Fahrzeugtür angeordnet ist. Der Schließzylinder 30 weist ein Zylindergehäuse 31 auf, innerhalb dessen ein Zylinderkern 32 drehbar gelagert ist. Der Zylinderkern 32 weist zahlreiche federbelastete Zuhalteelemente 41 , 42 auf. Ferner ist der Zylinderkern 32 mit einem Schlüsselkanal 33 ausgeführt, in den der Schlüssel 10 einbringbar ist. Figures 1 to 4 show purely schematically a locking device of a motor vehicle with a key 10 and a lock cylinder 30 which is arranged in a vehicle door. The lock cylinder 30 has a cylinder housing 31, within which a cylinder core 32 is rotatably mounted. The cylinder core 32 has numerous spring-loaded locking elements 41, 42. Furthermore, the cylinder core 32 is designed with a key channel 33 into which the key 10 can be inserted.
Ist der Schlüssel 10 nicht innerhalb des Schlüsselkanals 33 eingesteckt, ragen die Zuhalteelemente 41 , 42 mit ihren Vorsprüngen 41 a, 42a in den Schlüsselkanal 33 und sperren gleichzeitig eine Drehung des Zylinderkerns 32 innerhalb des Zylindergehäuses 31 , welches explizit nicht zeichnerisch dargestellt ist. Im vorliegenden Fall handelt es sich bei den Zuhalteelementen 41 , 42 um Plättchenzuhaltungen. Diese Zuhalteelemente 41 , 42 werden beim Einführen eines ordnungsgemäßen„richtigen" Schlüssels 10 derart verstellt, dass die Zuhalteelemente 41 , 42 nicht mehr über die Mantelfläche des Zylinderkerns 32 hinausragen, und der Zylinderkern 32 somit im Zylindergehäuse 31 drehbar ist. Durch eine Drehbewegung des eingesteckten Schlüssels 10 kann der Benutzer daraufhin eine Betätigungseinrichtung des Kraftfahrzeuges mittels der Schließvorrichtung entriegeln und/oder verriegeln, je nach Drehrichtung des Schlüssels 10. Ebenfalls ist durch die Drehbewegung des Schlüssels 10 ein Schalter betätigbar, der die Zündung, Spannung für elektronische Bauteile des Kraftfahrzeuges etc. aktiviert und/oder deaktiviert. If the key 10 is not inserted within the keyway 33, the tumblers 41, 42 protrude with their projections 41 a, 42 a in the keyway 33 and lock at the same time a rotation of the cylinder core 32 within the cylinder housing 31, which is not explicitly shown in the drawing. In the present case, the tumblers 41, 42 are platelet tumblers. These locking elements 41, 42 are displaced during insertion of a proper "correct" key 10 such that the locking elements 41, 42 no longer protrude beyond the lateral surface of the cylinder core 32, and the cylinder core 32 is thus rotatable in the cylinder housing 31. By a rotational movement of the inserted Key 10, the user then unlock an actuator of the motor vehicle by means of the locking device and / or lock, depending on the direction of rotation of the key 10. Also by the rotational movement of the key 10, a switch can be actuated, the ignition, voltage for electronic components of the motor vehicle, etc. activated and / or deactivated.
Wie in Fig. 1 bis Fig. 3 deutlich zu erkennen ist, weist der Schlüssel 10 Außenflächen 13, 14, 15 auf, die mit Steuerbahnen 11 , 12 ausgeführt sind, die beim Einführen des Schlüssels 10 in den Schlüsselkanal 33 auf die Zuhalteelemente 41 , 42 sowie auf die Vorsprünge 41 a, 42a der Zuhalteelemente 41 , 42 wirken. Die Außenflächen 13, 14, 15 des Schlüssels 10 sind mit zwei Schmalseiten 14, 15 und zwei Breitseiten 13 ausgeführt. Jede Breitseite 13 weist eine erste Steuerbahn 1 1 auf, die als Steuernut 11 ausgebildet ist. Das bedeutet, dass jeweils eine Breitseite 13 mit jeweils einer Steuernut 1 1 versehen ist. Die erste Schmalseite 14 ist mit einer zweiten Steuerbahn 12 ausgeführt, die eine hervorstehende Steuerrippe 12 ist. Die Steuernuten 1 1 sowie die Steuerrippe 12 sind ferner mit ersten Führungsflächen 16 sowie zweiten Führungsflächen 17 ausgestattet, die eine individuelle Topographie der Steuerbahnen 11 , 12 bestimmen und somit jeweils eine Codebahn bilden. As can be clearly seen in FIGS. 1 to 3, the key 10 has outer surfaces 13, 14, 15, which are designed with control tracks 11, 12 which are in the insertion of the key 10 in the keyway 33 on the tumblers 41, 42 and the projections 41 a, 42 a of the tumblers 41, 42 act. The outer surfaces 13, 14, 15 of the key 10 are designed with two narrow sides 14, 15 and two broad sides 13. Each broad side 13 has a first control track 1 1, which is designed as a control groove 11. This means that in each case one broad side 13 is provided with a respective control groove 1 1. The first narrow side 14 is designed with a second control track 12, which is a protruding control rib 12. The control grooves 1 1 and the control rib 12 are further equipped with first guide surfaces 16 and second guide surfaces 17 which determine an individual topography of the control tracks 11, 12 and thus each form a code track.
Die zweite Schmalseite 15 des Schlüssels 10 ist als ebene Fläche ausgeführt, das bedeutet, dass im Gegensatz zu der ersten Schmalseite 14 und beiden Breitseiten 13 die erste Schmalseite 15 steuerbahnfrei ausgeführt ist. Im vorliegenden Ausführungsbeispiel ist der Schlüssel 10 aus einem vierkantigen Flachprofil gebildet, wobei die zweite Schmalseite 15 zu den Breitseiten 13 rechtwinklig ausgerichtet ist. Wie in Fig. 1 und Fig. 2 gut zu erkennen ist, erstreckt sich die erste Steuerbahn 1 1 entlang der Längserstreckung des Schlüssels 10, wobei die erste Steuerbahn 1 1 in einigen Bereichen der Breitseite 13 bis zur gemeinsamen Kante 18 der Breitseite 13 und der zweiten Schmalseite 15 verlaufen kann. Somit kann möglichst die gesamte Höhe der Breitseite 13 für die erste Steuerbahn 1 1 ausgenutzt werden, wodurch die Kompaktheit des Schlüssels 10 erhöht wird. The second narrow side 15 of the key 10 is designed as a flat surface, which means that in contrast to the first narrow side 14 and two broad sides 13, the first narrow side 15 is executed free of tax. In the present embodiment, the key 10 is formed from a four-edged flat profile, wherein the second narrow side 15 is aligned at right angles to the broad sides 13. As can be clearly seen in FIGS. 1 and 2, the first control track 1 1 extends along the longitudinal extension of the key 10, wherein the first control track 1 1 in some areas of the broad side 13 to the common edge 18 of the broad side 13 and second narrow side 15 can run. Thus, if possible, the entire height of the broad side 13 can be utilized for the first control track 1 1, whereby the compactness of the key 10 is increased.
Die Steuernut 11 ist ferner am freien Ende 21 des Schlüssels 10 trichterartig verbreitert zur eigentlichen Bahnbreite 19 der Steuernut 1 1 ausgeführt, um den Schlüssel 10 leichter in den Schlüsselkanal 33 des Schließzylinders 30 einzufädeln. Im übrigen Verlauf außerhalb des freien Endes 21 des Schlüssels 10 weist die Steuernut 11 zu beiden Seiten der Breitseite 13 eine gleich bleibende Bahnbreite 19 auf. Analoges gilt auch für die Steuerrippe 12, die ebenfalls eine im Wesentlichen konstante Wandstärke 20, die auch als Rippenbreite 20 bezeichnet werden kann, aufweist. Selbstverständlich können die Bahnbreite 19 sowie die Rippenbreite 20 in unterschiedlichen Schlüsselabschnitten variieren, welches explizit nicht dargestellt ist. The control groove 11 is further widened like a funnel at the free end 21 of the key 10 to the actual web width 19 of the control groove 1 1 executed to thread the key 10 more easily in the keyway 33 of the lock cylinder 30. In the rest of the course outside the free end 21 of the key 10, the cam 11 has on both sides of the broad side 13 a constant web width 19. The same applies to the control rib 12, which also has a substantially constant wall thickness 20, which may also be referred to as rib width 20 has. Of course, the web width 19 and the rib width 20 in different key sections vary, which is not explicitly shown.
Wie in Fig. 3 zu erkennen ist, sind die Zuhalteelemente 41 , 42, die innerhalb des Zylinderkerns 32 verschiebbar gelagert sind, mit mindestens einem Vorsprung 41a, 42a ausgeführt. Ist der Schlüssel 10 nicht im Schlüsselkanal 33 eingeführt, wie es in Fig. 3 dargestellt ist, ragen die Vorsprünge 41a, 42a in den Schlüsselkanal 33. Der Schließzylinder 30 ist im dargestellten Ausführungsbeispiel durch zwei Arten von Zuhalteelementen 41 , 42 ausgestattet. Wie in Fig. 3 angedeutet ist, kann ein erstes Zuhalteelement 41 der ersten Art in eine erste radiale Richtung 43 zur Zylinderachse 34 verschoben werden, wobei die erste radiale Richtung 43 der Vorsprünge 41a die sich im linken Bereich des Schlüsselkanals 33 befinden, nach unten gerichtet ist. Die erste radiale Richtung 43 der Vorsprünge 41 a die sich im rechten Bereich des Schlüsselkanals 33 befinden, ist hierbei entgegengesetzt ausgerichtet. Das zweite Zuhalteelement 42 der zweiten Art ist in eine zweite radiale Richtung 44 verschiebbar, die senkrecht zur ersten radialen Richtung 43 ausgerichtet ist. As can be seen in Fig. 3, the tumblers 41, 42 which are slidably mounted within the cylinder core 32, with at least one projection 41 a, 42 a executed. If the key 10 is not inserted in the keyway 33, as shown in Fig. 3, protrude the projections 41 a, 42 a in the keyway 33. The lock cylinder 30 is in the illustrated embodiment by two types of locking elements 41, 42 equipped. As indicated in FIG. 3, a first locking element 41 of the first type can be displaced in a first radial direction 43 to the cylinder axis 34, wherein the first radial direction 43 of the projections 41 a which are located in the left area of the keyway 33 directed downward is. The first radial direction 43 of the projections 41 a which are located in the right area of the keyway 33, this is oppositely oriented. The second locking element 42 of the second type is displaceable in a second radial direction 44, which is aligned perpendicular to the first radial direction 43.
Die erste Steuerbahn 11 weist erste Führungsflächen 16 und die zweite Steuerbahn 12 zweite Führungsflächen 17 auf. Hierbei wirken die ersten Führungsflächen 16 auf mindestens ein erstes Zuhalteelement 41 sowie den Vorsprung 41 a. Die zweiten Führungsflächen 17 wirken analog auf mindestens ein zweites Zuhalteelement 42 sowie den Vorsprung 42a. Das bedeutet, dass während des Einführens des Schlüssels 10 über die profilierten Führungsflächen 16, 17 die Zuhalteelemente 41 , 42 in die erste und die zweite radiale Richtung 43, 44 entsprechend bewegt werden und somit innerhalb des Zylinderkerns 32 sortiert werden, damit beim eingesteckten Schlüssel 10 eine Drehbewegung des Schlüssels 10 sowie des Zylinderkerns 32 innerhalb des Zylindergehäuses 31 möglich ist. The first control track 11 has first guide surfaces 16 and the second control track 12 second guide surfaces 17. Here, the first guide surfaces 16 act on at least one first locking element 41 and the projection 41 a. The second guide surfaces 17 act analogously to at least one second locking element 42 and the projection 42 a. This means that during the insertion of the key 10 on the profiled guide surfaces 16, 17, the tumblers 41, 42 in the first and second radial directions 43, 44 are moved accordingly and thus sorted within the cylinder core 32 so that the inserted key 10th a rotational movement of the key 10 and the cylinder core 32 within the cylinder housing 31 is possible.
Die Zuhalteelemente 41 , 42 sind an der der zweiten Schmalseite 15 zugewandten Seite vorsprungfrei ausgeführt, das bedeutet, dass die Zuhalteelemente 41 , 42 in diesem Bereich der ebenen, flächigen Ausgestaltung der zweiten Schmalseite 15 geometrisch angepasst sind. Beim eingesteckten Schlüssel 10 liegt die zweite Schmalseite 15 unmittelbar an der benachbarten, zugewandten Wandung 33a des Schüsselkanals 33 an. The tumblers 41, 42 are designed without protrusions on the side facing the second narrow side 15, which means that the tumblers 41, 42 are geometrically adjusted in this area of the planar, planar configuration of the second narrow side 15. When inserted key 10, the second narrow side 15 is located directly on the adjacent, facing wall 33a of the bowl channel 33 at.
Im vorliegenden Fall ist die Anordnung der ersten Zuhalteelemente 41 und der zweiten Zuhalteelemente 42 in abwechselnder Reihenfolge angeordnet. Hierbei sind eine Vielzahl an ersten Zuhalteelementen 41 und zweiten Zuhalteelementen 42 innerhalb des Schließzylinders 30 vorgesehen. Die in dem Ausführungsbeispiel beschriebenen Steuerbahnen 11 , 12 können selbstverständlich entlang der gesamtem Erstreckung des Schlüssels 10 vorgesehen sein. Die Erstreckungslängen der ersten und der zweiten Steuerbahn 1 1 , 12 können auch unterschiedlich groß sein. Im vorliegenden Ausführungsbeispiel ist der erfindungsgemäße Schlüssel 10 nur in einer möglichen Position innerhalb des Schlüsselkanals 33 einsetzbar, das bedeutet, dass der Schlüssel 10 nicht als Wendeschlüssel Verwendung finden kann. In the present case, the arrangement of the first tumblers 41 and the second tumblers 42 is arranged in an alternating sequence. Here, a plurality of first tumblers 41 and second tumblers 42 are provided within the lock cylinder 30. The control tracks 11, 12 described in the exemplary embodiment may of course be provided along the entire extent of the key 10. The extension lengths of the first and the second control track 1 1, 12 may also be different in size. In the present embodiment, the key 10 according to the invention can only be used in a possible position within the key channel 33, which means that the key 10 can not be used as a reversible key.
