Description

Die Erfindung betrifft einen Schließzylinder mit einem in einem Gehäuse drehbaren Kern und mit einem Schließbart, mit einem in dem Kern angeordneten Schließkanal zur Einführung eines Schlüssels und mit einem einen Formschluss des Schließbartes gegenüber dem Kern wahlweise erzeugenden oder lösenden Kupplungsschieber.The invention relates to a lock cylinder with a rotatable core in a housing and a cam, with a arranged in the core closing channel for introducing a key and with a positive engagement of the cam against the core selectively generating or releasing coupling slide.

Ein solcher, als Doppelschließzylinder ausgebildeter Schließzylinder ist beispielsweise aus der DE 103 17 448 A1 bekannt. Bei diesem Schließzylinder wird ein Betätigungselement von einem in den Schließkanal eingeführten Schlüssel axial verschoben. Das Betätigungselement gibt die Bewegung eines Mitnehmers frei, welcher von einer Federkraft in Richtung Schließbart vorgespannt ist. In der freigegebenen Stellung des Mitnehmers wird ein Formschluss zwischen dem Kern und dem Schließbart erzeugt. Ein Entriegeln des Schließzylinders wird auch dann ermöglicht, wenn der zweite Kern mit dem Schließbart gekoppelt ist.Such, designed as a double lock cylinder lock cylinder is for example from the DE 103 17 448 A1 known. In this lock cylinder, an actuator is axially displaced by a key inserted into the lock channel. The actuating element releases the movement of a driver, which is biased by a spring force in the direction of the cam. In the released position of the driver, a positive connection between the core and the cam is generated. Unlocking of the lock cylinder is also made possible when the second core is coupled to the lock bit.

Weiterhin ist aus der EP 1 719 861 A2 ein Schließzylinder für ein elektronisches Schließsystem bekannt geworden, bei dem ein Ringelement mit einer inneren Betätigungswelle gekoppelt ist und ein axial verschiebliches Koppelungselement einen Formschluss zwischen dem Ringelement und dem Schließbart erzeugt oder löst.Furthermore, from the EP 1 719 861 A2 a lock cylinder for an electronic locking system has become known, in which a ring element is coupled to an inner actuating shaft and an axially displaceable coupling element generates or releases a positive connection between the ring element and the cam.

Nachteilig bei den bekannten Schleißzylindern ist jedoch, dass sie sehr aufwändig aufgebaut sind. Insbesondere erfordert die Ansteuerung des Mitnehmers über das Betätigungselement sehr viele Bauteile.A disadvantage of the known Schleißzylindern, however, that they are constructed very expensive. In particular, the control of the driver via the actuating element requires a large number of components.

Der Erfindung liegt das Problem zugrunde, einen Schließzylinder der eingangs genannten Art so weiter zu bilden, dass er besonders einfach aufgebaut ist und eine hohe Stabilität aufweist.The invention is based on the problem, so to form a lock cylinder of the type mentioned so that it is particularly simple and has a high stability.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Kupplungsschieber zur Lösung oder Erzeugung des Formschlusses radial verschieblich in dem Kern geführt ist, dass eine Schlüsselaufnahme des Kupplungsschiebers eine Schlüsselaufnahmeschräge zur radialen Bewegung des Kupplungsschiebers bei in den Schließkanal eingeführten Schlüssel hat und dass die radiale Bewegungsrichtung des Kupplungsschiebers in Richtung der längsten radialen Erstreckung des Schließkanals verläuft.This problem is inventively solved in that the coupling slide is guided radially displaceable in the core for solving or generating the positive connection, that a key receptacle of the coupling slide a key receiving slope for the radial movement of the coupling slide in inserted into the lock key has and that the radial direction of movement of the coupling slide extends in the direction of the longest radial extent of the closing channel.

Durch diese Gestaltung wird der Formschluss zwischen Schließbart und Kern durch eine radiale Verschiebung des Kupplungsschiebers erzeugt oder gelöst. Durch die Anordnung der Bewegungsrichtungen vermag die Schlüsselaufnahmeschräge sehr lang gestaltet sein und damit große Kräfte aufnehmen. Zudem wird eine Belastung des Schlüssels senkrecht auf seine Flachseite vermieden. Der Schließzylinder ist hierdurch besonders kompakt und einfach aufgebaut.By this design, the positive connection between the lock bit and core is generated or released by a radial displacement of the coupling slide. By arranging the directions of movement, the key receiving bevel can be made very long and thus absorb large forces. In addition, a load of the key is avoided perpendicular to its flat side. The lock cylinder is thus particularly compact and simple.

Der Kupplungsschieber wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zuverlässig von dem in den Schließkanal eingeführten Schlüssel geführt, wenn eine Spitze des Schlüssels seitlich umgreifende Stege des Kupplungsschiebers von der Schlüsselaufnahmeschräge beabstandet sind. Damit kann eine sehr lagestabile Dreipunkt Abstützung des Mitnehmers an dem Schlüssel erzeugt werden.According to another advantageous development of the invention, the coupling slide is guided reliably by the key inserted into the closing channel when a tip of the key laterally encompasses webs of the coupling slide which are spaced from the key receiving bevel. Thus, a very stable position three-point support of the driver can be generated on the key.

Die Übertragung des Drehmoments von dem Kupplungsschieber in Richtung des Schließbartes gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn eine Schließbartkupplung des Kupplungsschiebers mit einer Schließbarthülse zusammenwirkende Formschlussflächen hat. Die drehfeste Wirkverbindung der Schließbarthülse mit dem Schließbart kann über eine einfache Verzahnung, eine Verschraubung oder durch ein einstückiges Bauteil Schließbarthülse und Schließbart erfolgen. Die Schließbarthülse kann in verschiedenen Längen, abhängig von der Länge des Schließzylinders ausgeführt werden.The transmission of the torque of the coupling slide in the direction of the cam designed according to another advantageous embodiment of the invention is particularly simple when a cam coupling of the coupling slide has cooperating with a lock bit sleeve form-fitting surfaces. The non-rotatable operative connection of the lock bit sleeve with the cam can be done via a simple toothing, a screw or by a one-piece component Schließbarthülse and cam. The lock bit sleeve can be made in various lengths, depending on the length of the lock cylinder.

Das Einschieben des Schlüssels in den Schleißkanal bei verdrehtem Schließbart wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach ermöglicht, wenn der Kupplungsschieber axial verschieblich geführt ist und die Formschlussflächen in der einen axialen Stellung des Kupplungsschiebers mit denen der Schließbarthülse zusammenwirken und in der anderen axialen Stellung die Formschlussflächen voneinander getrennt sind. Durch diese Gestaltung ist der Kupplungsschieber für dieselbe Funktion axial und radial verschieblich geführt. Damit kann der Schlüssel vollständig in den Schließkanal eingeschoben werden, um Stiftzuhaltungen anzusteuern. Dabei wird der Kupplungsschieber axial und damit in der Achse des drehbaren Kerns verschoben. Da die Formschlussflächen des Kupplungsschiebers und der Schließbarthülse bei verdrehtem Schließbart nicht zusammen wirken, wird zunächst auch kein Formschluss zwischen dem Kern und der Hülse erzeugt. Jedoch kann nach einer anfänglichen Drehung des Kerns die Formschlussflächen ineinander greifen und damit in der vorgesehenen Drehstellung der Formschluss zwischen Kern und Schließbarthülse erzeugt werden.The insertion of the key in the wear channel with twisted cam is easily made possible according to another advantageous embodiment of the invention, when the coupling slide is guided axially displaceable and the form-fitting surfaces in one axial position of the coupling slide with those of the lock bit sleeve and cooperate in the other axial position the Molded interfaces are separated from each other. By this design, the coupling slide for the same function is guided axially and radially displaceable. Thus, the key can be fully inserted into the lock channel to control pin tumblers. In this case, the coupling slide is moved axially and thus in the axis of the rotatable core. Since the positive-locking surfaces of the coupling slide and the lock bit sleeve do not work together when the locking cam is twisted, no positive connection is initially produced between the core and the sleeve. However, after an initial rotation of the core, the interlocking surfaces may intermesh grab and thus be generated in the intended rotational position of the positive connection between the core and lock bit sleeve.

Die zusammenwirkenden Formschlussflächen der Schließbartkupplung und des Kupplungsschiebers gestalten sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die Schließbarthülse und der Kupplungsschieber einander gegenüberstehende Nasen aufweisen, wenn die Nasen in einer radial inneren Stellung des Kupplungsschiebers einen Abstand zueinander haben und in einer radial äußeren Stellung des Kupplungsschiebers einen Formschluss in Drehrichtung zwischen der Schließbarthülse und dem Kupplungsschieber erzeugen.The cooperating form-fitting surfaces of the lock cam and the coupling slide are structurally particularly simple according to another advantageous embodiment of the invention, when the cam bit and the coupling slide have opposing lugs, if the lugs in a radially inner position of the coupling slide have a distance from one another and in a radial outside position of the coupling slide produce a positive connection in the direction of rotation between the lock bit sleeve and the coupling slide.

Der Kupplungsschieber gestaltet sich gemäß einer vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die Schlüsselaufnahmeschräge auf einem gemeinsamen axialen Abschnitt wie die Stege angeordnet ist und in das Ende des Schließkanals hineinragt. Durch diese Gestaltung können die Stege und die Schlüsselaufnahmeschräge die Spitze des in den Schließkanal eingeführten Schlüssels umgreifen.The coupling slide is structurally particularly simple according to an advantageous development of the invention, when the key receiving bevel is arranged on a common axial portion as the webs and projects into the end of the closing channel. With this configuration, the webs and the key receiving bevel can embrace the tip of the inserted into the lock channel key.

Die Verbindung des Kupplungsschiebers mit dem Schließbart gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kompakt, wenn die Schließbartkupplung in axialer Richtung von der Schlüsselaufnahmeschräge beabstandet ist.The connection of the coupling slide with the lock bit designed according to another advantageous embodiment of the invention is particularly compact when the lock cam is spaced in the axial direction of the key receiving bevel.

Der Kupplungsschieber hat gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine hohe Stabilität, wenn zwischen der Schließbartkupplung und der Schlüsselaufnahmeschräge ein Grundteil des Kupplungsschiebers angeordnet ist.The coupling slide has, according to another advantageous embodiment of the invention, a high stability when a base part of the coupling slide is arranged between the lock cam and the key receiving bevel.

Die Führung des Kupplungsschiebers innerhalb des Schließzylinders gestaltet sich konstruktiv besonders einfach, wenn das Grundteil und der Kern miteinander korrespondierende Führungsflächen haben. Die Führungsflächen sind derart anzuordnen, dass eine axiale und radiale Beweglichkeit des Kupplungsschiebers ermöglicht ist.The leadership of the coupling slide within the lock cylinder designed structurally particularly simple when the base and the core have mutually corresponding guide surfaces. The guide surfaces are to be arranged such that an axial and radial mobility of the coupling slide is made possible.

Figur 1 zeigt einen Schließzylinder mit zwei in einem Gehäuse 1 drehbar gelagerten Kernen 2, 3. Die Bewegung der Kerne 2, 3 lässt sich über nicht dargestellte Stiftzuhaltungen wahlweise mit dem Gehäuse 1 verbinden oder freigeben. Die Kerne 2, 3 weisen jeweils einen Schließkanal 4, 5 zur Einführung eines Schlüssels 6 zum Ansteuern der Stiftzuhaltungen auf. Zwischen den Kernen 2, 3 ist ein Schließbart 7 angeordnet. Der Schlüssel 6 ist als Flachschlüssel ausgebildet. Der Schließbart 7 ist in Drehrichtung formschlüssig mit zwei axial verschieblichen Schließbarthülsen 8, 9 verbunden. Die Schließbarthülsen 8, 9 sind von einem Federelement 10 auf Abstand zueinander gehalten und damit in Richtung der Kerne 2, 3 vorgespannt. Jeweils ein Kupplungsschieber 11, 12 ist drehfest in den Kernen 2, 3 geführt und ermöglicht die Erzeugung oder Lösung eines Formschlusses des jeweiligen Kerns 2, 3 mit der jeweiligen Schließbarthülse 8, 9. Die Kupplungsschieber 11, 12 sind über Bolzen 27, 28 mittels eines schematisch dargestellten Federelementes 26 auf Abstand zueinander und damit in Richtung der Kerne 2, 3 vorgespannt. FIG. 1 shows a lock cylinder with two rotatably mounted in a housing 1 cores 2, 3. The movement of the cores 2, 3 can be connected via not shown Stiftzuhaltungen either with the housing 1 or release. The cores 2, 3 each have a closing channel 4, 5 for the introduction of a key 6 for driving the pin tumblers. Between the cores 2, 3, a cam 7 is arranged. The key 6 is designed as a flat key. The cam 7 is positively connected in the direction of rotation with two axially displaceable cam sleeves 8, 9. The Schließbarthülsen 8, 9 are held by a spring element 10 at a distance from each other and thus biased in the direction of the cores 2, 3. In each case, a coupling slide 11, 12 is rotatably guided in the cores 2, 3 and allows the generation or solution of a positive connection of the respective core 2, 3 with the respective Schließbarthülse 8, 9. The coupling slide 11, 12 via bolts 27, 28 by means of a schematically illustrated spring element 26 at a distance from each other and thus biased in the direction of the cores 2, 3.

In der dargestellten Stellung ist der Schlüssel 6 nur teilweise in den einen Schließkanal 4 eingeschoben. Damit sind Kupplungsschieber 11 und Schließbarthülse 8 auf dieser Seite des Schließzylinders axial voneinander getrennt. Der Formschluss des Kupplungsschiebers 11 ist daher von der Schließbarthülse 8 gelöst. Der Formschluss des anderen Kupplungsschiebers 12 von der anderen Schließbarthülse 9 ist ebenfalls gelöst, so dass der Schließbart 7 frei drehbar ist. Damit ist dieser Schließzylinder für den Einsatz in so genannten Paniktüren oder für elektrisch ansteuerbare Schlösser geeignet, bei denen die Möglichkeit bestehen muss, den Schließbart 7 ungehemmt von der Ansteuerung der Kerne 2, 3 zu bewegen.In the illustrated position, the key 6 is only partially inserted into the one closing channel 4. Thus, the coupling slide 11 and cam 8 are on this page the lock cylinder axially separated. The positive connection of the coupling slide 11 is therefore released from the lock bit sleeve 8. The positive connection of the other coupling slide 12 of the other cam sleeve 9 is also released, so that the cam 7 is freely rotatable. Thus, this lock cylinder is suitable for use in so-called panic doors or for electrically controllable locks in which the possibility must exist, the cam 7 unrestrained to move from the control of the cores 2, 3.

Figur 2 zeigt eine Schnittdarstellung durch den Schließzylinder aus Figur 1 entlang der Linie II - II im Bereich einer Schließbartkupplung 13 einer der Kupplungsschieber 11 mit der gegenüberstehenden Schließbarthülse 8. Die Schließbarthülse 8 hat eine radial nach innen weisende Nase 14, während der Kupplungsschieber 11 eine radial nach außen weisende Nase 15 hat. FIG. 2 shows a sectional view through the lock cylinder FIG. 1 along the line II - II in the region of a Schließbartkupplung 13 one of the coupling slide 11 with the opposite cam disc 8. The cam 8 has a radially inwardly facing nose 14, while the coupling slide 11 has a radially outwardly facing nose 15.

Schiebt man ausgehend von der Stellung aus Figur 1 den Schlüssel 6 vollständig in den Schließkanal 4 hinein, gelangt die Spitze des Schlüssels 6 gegen den Kupplungsschieber 11 und bewegt diesen in radialer Richtung und in axialer Richtung. Bei einer entsprechenden Drehstellung des Schließbartes 7 ist jedoch ein Schließen der Schließbartkupplung 13 verhindert. In dieser Drehstellung drückt der Kupplungsschieber 11 die Schließbarthülse 8 in den Schließbart 7. Der Kupplungsschieber 11 und die Schließbarthülse 8 liegen damit übereinander, so dass kein Formschluss der beiden Bauteile in Drehrichtung vorliegt.Moves out from the position FIG. 1 the key 6 completely into the closing channel 4, the tip of the key 6 passes against the coupling slide 11 and moves it in the radial direction and in the axial direction. In a corresponding rotational position of the cam 7, however, a closing of the lock cam 13 is prevented. In this rotational position of the coupling slide 11 presses the lock bit sleeve 8 in the cam 7. The coupling slide 11 and the lock bit sleeve 8 are thus one above the other, so that there is no positive connection of the two components in the direction of rotation.

Figur 4 zeigt zur Verdeutlichung dass durch das Einführen des Schlüssels 6 in den Schließkanal 4 die Nasen 14, 15 durch die radiale Bewegung des Kupplungsschiebers 11 übereinander liegen. Damit sind Kupplungsschieber 11 und Schließbarthülse 8 in Drehrichtung immer noch voneinander getrennt. Weiterhin zeigen die Figuren 2 und 4, dass die radiale Bewegungsrichtung des Kupplungsschiebers 11 in Richtung der längsten radialen Erstreckung des als Flachschlüssel ausgebildeten Schlüssels 6 und damit des Schließkanals 4 verlaufen. FIG. 4 shows to illustrate that by inserting the key 6 in the closing channel 4, the lugs 14, 15 are superimposed by the radial movement of the coupling slide 11. Thus, coupling slide 11 and cam 8 are still separated from each other in the direction of rotation. Furthermore, the show Figures 2 and 4 in that the radial direction of movement of the coupling slide 11 extends in the direction of the longest radial extent of the key 6 designed as a flat key and thus of the closing channel 4.

Durch das vollständige Einführen des Schlüssels 6 in den Schließkanal 4 sind jedoch die Stiftzuhaltungen angesteuert und der Kern 2 kann gegenüber dem Gehäuse 1 verdreht werden. Dabei gleitet der Kupplungsschieber 11 über die Schließbarthülse 8, bis die Schließbartkupplung 13 einrastet und einen Formschluss zwischen Kupplungsschieber 11 und Schließbarthülse 8 in Drehrichtung erzeugt. Diese Stellung ist in Figur 5 dargestellt. Die Schließbarthülse 8 ist wieder in den Kern 2 gedrückt. Der Kupplungsschieber 11 dringt axial in die Schließbarthülse 8 ein. Anschließend kann der Kern 2 und auch der der Schließbart 7 mittels des Schlüssels 6 gedreht werden.Due to the complete insertion of the key 6 in the closing channel 4, however, the pin tumblers are driven and the core 2 can be rotated relative to the housing 1. In this case, the coupling slide 11 slides over the lock bit sleeve 8 until the lock cam 13 engages and generates a positive connection between the coupling slide 11 and the lock bit sleeve 8 in the direction of rotation. This position is in FIG. 5 shown. The lock bit sleeve 8 is pressed back into the core 2. The coupling slide 11 penetrates axially in the lock bit sleeve 8 a. Subsequently, the core 2 and also the cam 7 can be rotated by means of the key 6.

Figur 6 zeigt in einer Schnittdarstellung durch die Schließbartkupplung 13 aus Figur 5 entlang der Linie VI - VI dass die Nase 15 des Kupplungsschiebers 11 und die Nase 14 der Schließbarthülse 8 ineinander greifen und damit Formschlussflächen 16, 17 zur Kupplung des Kupplungsschiebers 11 mit der Schließbarthülse 8 in Drehrichtung erzeugen. FIG. 6 shows in a sectional view through the lock cam 13 FIG. 5 along the line VI - VI that the nose 15 of the coupling slide 11 and the nose 14 of the lock bit sleeve 8 engage each other and thus form fit surfaces 16, 17 for coupling the coupling slide 11 with the lock bit sleeve 8 in the direction of rotation.

Figur 7 zeigt vergrößert einen der Kupplungsschieber 11 in einer perspektivischen Darstellung zusammen mit der Spitze des Schlüssels 6. Der Kupplungsschieber 11 hat eine Schlüsselaufnahme 18 zur Aufnahme der Spitze des Schlüssels 6, ein Grundteil 19, welches in dem Kern 2 geführt ist, und eine Hälfte der Schließbartkupplung 13, welche mit der Schließbarthülse 8 aus den Figuren 1 bis 6 zusammenwirkt. Das Grundteil 19 hat Führungsflächen 20, mit denen es drehfest sowie axial und radial verschieblich mit den Kern 2 verbunden ist. Die Schlüsselaufnahme 18 hat eine Schlüsselaufnahmeschräge 21, welche mit einer Rampe 22 an der Spitze des Schlüssels 6 zur radialen Bewegung des Kupplungsschiebers 11 zusammenwirkt. Die Spitze des Schlüssels 6 seitlich umgreifende Stege 23 sind von der Schlüsselaufnahmeschräge 21 beabstandet. Die Enden des Grundteils 19 begrenzen mit Anschlagflächen 24 die radiale Beweglichkeit des Kupplungsschiebers 11. FIG. 7 shows enlarged one of the coupling slide 11 in a perspective view together with the tip of the key 6. The coupling slide 11 has a key receptacle 18 for receiving the tip of the key 6, a base 19, which is guided in the core 2, and a half of the lock cam 13, which with the lock bit sleeve 8 from the FIGS. 1 to 6 interacts. The base 19 has guide surfaces 20 with which it is rotatably and axially and radially slidably connected to the core 2. The key holder 18 has a key receiving bevel 21, which cooperates with a ramp 22 at the tip of the key 6 for the radial movement of the coupling slide 11. The tip of the key 6 laterally encompassing webs 23 are spaced from the key receiving bevel 21. The ends of the base 19 limit with stop surfaces 24, the radial mobility of the coupling slide eleventh

Figur 8 zeigt den Kupplungsschieber 11 aus Figur 4 von der gegenüberliegenden Seite auf die Schließbartkupplung 13 mit der Nase 15. FIG. 8 shows the coupling slide 11 FIG. 4 from the opposite side to the lock dog clutch 13 with the nose 15.

Da die Schlüsselaufnahmeschräge 21 des Kupplungsschiebers 11 mit der Rampe 22 der Spitze des Schlüssels 6 zusammenwirkt, genügt es nicht zum Entriegeln des Schließzylinders nur die Stiftzuhaltungen anzusteuern. Zusätzlich muss zur Erzeugung des Formschlusses des Kerns 2 mit dem Schließbart 7 auch der Kupplungsschieber 11 angesteuert werden.Since the key receiving bevel 21 of the coupling slide 11 cooperates with the ramp 22 of the tip of the key 6, it is not enough to unlock the lock cylinder to control only the pin tumblers. In addition, to produce the positive connection of the core 2 with the cam 7 and the coupling slide 11 must be controlled.
