Description

Die Erfindung betrifft einen Schließzylinder mit einem in einem Gehäuse bewegbaren Kern, mit einem elektrisch aktivierbaren Sperrmechanismus, mit einem in einer Ausnehmung des Gehäuses geführten und in eine Ausnehmung des Kerns bewegbaren Sperrriegel zur wahlweisen Blockierung oder Freigabe des Kerns, und mit einem in den Bewegungsbereich des Sperrriegels bewegbaren Blockierelement zur Blockierung oder Freigabe der Bewegung des Sperrriegels, und mit einem Federelement zur Vorspannung des Sperrriegels in die Ausnehmung.The invention relates to a lock cylinder with a in a housing movable core, with an electrically activated Locking mechanism, with one in a recess of the housing and guided into a recess of the core movable locking bolt for optional blocking or Release of the core, and with one in the range of motion the locking bar movable blocking element for blocking or releasing the movement of the locking bolt, and with a spring element for biasing the locking bolt in the recess.

Ein solcher Schließzylinder ist beispielsweise aus der DE 41 26 160 A1 bekannt. Bei diesem Schließzylinder hat der Sperrmechanismus einen Elektromagneten zur Bewegung des Blockierelements. Das Blockierelement ist in die die Bewegung des Sperrriegels blockierende Stellung vorgespannt und wird bei einer Freigabe des Schließzylinders gegen die Kraft der Feder von dem Elektromagneten zurückgezogen. Anschließend lässt sich der Kern gegenüber dem Gehäuse verdrehen. Dabei wird der Sperrriegel aus der Ausnehmung des Kerns in das Gehäuse zurückgedrückt. Die Vorspannung des Sperrriegels in die Ausnehmung des Kerns ermöglicht die Erzeugung einer Nullstellung, in der der Kern gegenüber dem Gehäuse verrastet ist.Such a lock cylinder is for example from the DE 41 26 160 A1. In this lock cylinder has the locking mechanism is an electromagnet for movement of the blocking element. The blocking element is in the Movement of the locking bolt biased blocking position and is at a release of the lock cylinder withdrawn from the electromagnet against the force of the spring. Subsequently, the core can be compared to the Turn the housing. Here, the locking bolt from the Recess of the core pushed back into the housing. The Preload of the locking bolt in the recess of the core allows the generation of a zero position in which the Core is locked relative to the housing.

Nachteilig bei dem bekannten Schließzylinder ist, dass zur Bewegung des Blockierelements gegen die Kraft des Federelements ein hoher Energiebedarf notwendig ist. Der Energiebedarf wird jedoch meist von einer in dem Schließzylinder angeordneten Batterie gedeckt, so dass der Schließzylinder einen hohen Wartungsbedarf zum Auswechseln der Batterie aufweist. Zudem muss insbesondere bei Schließzylindern, bei denen der Kern zur Entriegelung zweimal gedreht werden muss, der Elektromagnet während der gesamten Dauer des Schließvorgangs angesteuert werden. Weiterhin wird bei einer über einen längeren Zeitraum vorliegenden Schließberechtigung, beispielsweise wenn ein Schlüssel in dem Schließzylinder stecken bleibt, der Elektromagnet dauerhaft angesteuert, was den Energiebedarf weiter erhöht.A disadvantage of the known lock cylinder is that for moving the blocking element against the force of the spring element a high energy requirement is necessary. Of the However, energy demand is usually from one in the lock cylinder arranged battery, so that the Lock cylinder a high maintenance requirement for replacement the battery has. In addition, especially at Lock cylinders, where the core for unlocking must be turned twice, the electromagnet during the entire duration of the closing process to be controlled. Furthermore, at a over a longer period of time present locking authorization, for example if a key gets stuck in the lock cylinder, the electromagnet is permanently activated, which reduces the energy requirement further increased.

Weiterhin ist aus der DE 198 27 827 A1 ein Schließzylinder bekannt geworden, bei dem ein sogenannter Lavet-Motor einen Steuernocken bewegt. Der Steuernocken arbeitet mit einer Ausnehmung einer Sperrleiste zusammen. Auf der Sperrleiste sind Rollelemente von einem Federelement in eine Ausnehmung des Gehäuses vorgespannt. Der Lavet-Motor befindet sich damit im Kern. Nachteilig bei diesem Schließzylinder ist jedoch, dass der Sperrmechanismus eine große Anzahl von beweglichen Bauteilen benötigt und daher aufwändig zu montieren ist.Furthermore, from DE 198 27 827 A1 a lock cylinder become known, in which a so-called Lavet engine moved a control cam. The control cam works with a recess of a locking bar together. On the Locking bar are rolling elements of a spring element in biased a recess of the housing. The Lavet engine is thus at the core. A disadvantage of this Lock cylinder is, however, that the locking mechanism a large number of moving parts needed and therefore expensive to assemble.

Der Erfindung liegt das Problem zugrunde, einen Schließzylinder der eingangs genannten Art so zu gestalten, dass er einen besonders geringen Energiebedarf hat.The invention is based on the problem, a lock cylinder of the type mentioned above to be designed so that he has a very low energy requirement.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Sperrmechanismus einen elektromotorischen Antrieb aufweist, dass das Blockierelement auf einer Antriebswelle des elektromotorischen Antriebs drehfest angeordnet ist und von einer Blockierstellung, in der der Sperrriegel abgestützt ist, in eine Freigabestellung, in der die Bewegung des Sperrriegels freigegeben ist, bewegbar ist und dass die Ausnehmung des Kerns für den Sperrriegel oder der Sperrriegel eine in Bewegungsrichtung des Kerns weisende Rampe aufweist.This problem is inventively achieved in that the locking mechanism an electric motor drive that the blocking element on a drive shaft the electromotive drive rotatably arranged is and from a blocking position, in which the locking bolt is in a release position in which the Movement of the locking bar is released, is movable and that the recess of the core for the locking latch or the locking bar one in the direction of movement of the core has pointing ramp.

Durch diese Gestaltung wird das Blockierelement bei fehlender Schließberechtigung zum Entriegeln des erfindungsgemäßen Schließzylinders in die Blockierstellung gedreht oder es verbleibt in dieser Stellung, falls es sich zuvor in dieser Stellung befand. Beim Vorliegen einer Schließberechtigung wird das Blockierelement in die Freigabestellung verdreht und verbleibt anschließend in dieser Stellung. Damit wird das Blockierelement kraftlos in beide Stellungen verstellt und benötigt daher einen besonders geringen Energiebedarf. Nach dem Entriegeln des Schließzylinders kann der Sperrmechanismus beispielsweise nach einer vorgesehenen Zeitspanne angesteuert werden, um das Blockierelement in die Blockierstellung zu bewegen. Ein Federelement zur Vorspannung des Blockierelements in eine der Stellungen ist dank der Erfindung nicht erforderlich. Bei in Freigabestellung befindlichem Blokkierelement ermöglicht die Rampe die Bewegung des Sperrriegels durch eine Drehung des Kerns.By this design, the blocking element is missing Lock authorization for unlocking the invention Locking cylinder turned to the blocking position or it remains in that position, if it was previously in this position. If there is a locking authorization the blocking element is in the release position twisted and then remains in this Position. Thus, the blocking element is powerless in both Positions adjusted and therefore requires a special low energy requirement. After unlocking the Locking cylinder, the locking mechanism, for example be driven after a predetermined period of time to to move the blocking element into the blocking position. A spring element for biasing the blocking element in one of the positions is not required thanks to the invention. When in the release position befindlicher Blocking element the ramp allows the movement of the Locking bar by a rotation of the core.

Der Sperrmechanismus erfordert gemäß einer vorteilhaften Weiterbildung der Erfindung einen besonders geringen Bauraum, wenn eine Antriebswelle des elektromotorischen Antriebs parallel zu einer Drehachse des Kerns angeordnet ist.The locking mechanism requires according to an advantageous Development of the invention a particularly small space, if a drive shaft of the electric motor drive arranged parallel to a rotation axis of the core is.

Das Federelement erfordert gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders geringen Bauraum, wenn das Federelement als Blattfeder ausgebildet ist. Vorzugsweise ist das als Blattfeder ausgebildete Federelement zwischen Sperrriegel und Blockierelement angeordnet, so dass das Blockierelement das Federelement in Blockierstellung abstützt und damit mittelbar die Bewegung des Sperrriegels blockiert.The spring element requires according to another advantageous Development of the invention a particularly low Space when the spring element is designed as a leaf spring is. Preferably, this is designed as a leaf spring Spring element between locking bolt and blocking element arranged so that the blocking element, the spring element supported in blocking position and thus indirectly blocked the movement of the locking bolt.

Zur weiteren Verringerung des erforderlichen Bauraums für den Sperrmechanismus trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn der Sperrriegel eine Kugel aufweist oder aus einem vorzugsweise zweigeteilten Stift mit Anschrägung besteht, und durch Drehung des Kerns bei in Freigabestellung befindlichem Blockierelement zur Freigabe des Kerns aus einer Trennebene zwischen Kern und Gehäuse verdrängbar ist. Die Kugel bzw. der Stift lässt sich in Freigabestellung des erfindungsgemäßen Schließzylinders einfach aus der Trennebene zwischen Kern und Gehäuse infolge der aufeinandertreffenden schrägen Flächen herausdrücken und verbleibt beim Verdrehen des Kerns ganz oder bei zweigeteiltem Stift teilweise in dem Gehäuse. Bei in Sperrstellung befindlichem Blockierelement kann die Kugel oder der Stift nicht aus der Trennebene verschoben werden, so dass der Kern blockiert bleibt.To further reduce the required space for the locking mechanism carries it according to another advantageous Development of the invention, when the Locking bar has a ball or one of preferably two-part pin with chamfer exists, and by rotation of the core in the release position befindlichem Blocking element for releasing the core from a Parting plane between the core and housing is displaceable. The Ball or the pin can be in the release position of Locking cylinder according to the invention simply from the parting plane between core and housing as a result of the collision push out sloping surfaces and remain when twisting the core whole or at two-parted Pen partially in the housing. In befindlichem in blocking position Blocking element can be the ball or the pen not be moved out of the dividing plane, so that the Core remains blocked.

Der Sperrmechanismus vermag gemäß einer anderen vorteilhaften Weiterbildung der Erfindung hohe, auf den Kern einwirkende Kräfte abzustützen, wenn der Sperrriegel ein in einer den Kern durchdringenden kanalförmigen Ausnehmung geführtes Sperrglied aufweist, wenn das Sperrglied eine der kanalförmigen Ausnehmung entsprechende Länge aufweist, wenn die Kugel zwischen dem Sperrglied und dem Blockierelement angeordnet ist und wenn das Gehäuse auf dem dem Blockierelement gegenüberliegenden Ende der kanalförmigen Ausnehmung eine zweite Ausnehmung zur Aufnahme des freien Endes des Sperrriegels hat. Hierdurch dringt in Sperrstellung des erfindungsgemäßen Schließzylinders der Sperrriegel in einander gegenüberstehende Ausnehmungen des Gehäuses ein. In Freigabestellung des Schließzylinders wird das Sperrglied mit dem Kern mitgedreht und die Kugel im Gehäuse gehalten.The locking mechanism can according to another advantageous Development of the invention high, on the core supporting forces acting when the locking latch a in a core-penetrating channel-shaped recess guided locking member, when the locking member one of the channel-shaped recess corresponding length when the ball between the locking member and the Blocking element is arranged and when the housing up the opposite end of the blocking element of the channel-shaped Recess a second recess for receiving the free end of the locking bar has. hereby penetrates in locked position of the lock cylinder according to the invention the locking bar in facing each other Recesses of the housing. In release position of Locking cylinder, the locking member is rotated with the core and the ball held in the case.

Eine Leichtgängigkeit der Bewegung des Kerns in Freigabestellung des erfindungsgemäßen Schließzylinders lässt sich einfach sicherstellen, wenn das Sperrglied eine in der kanalförmigen Ausnehmung geführte und in die zweite Ausnehmung des Gehäuses bewegbare Kugel aufweist.A smooth movement of the core in the release position of the lock cylinder according to the invention leaves Just make sure when the locking member in a guided the channel-shaped recess and into the second Recess of the housing has movable ball.

Eine Bewegung des in Blockierstellung befindlichen Blokkierelements durch hohe, in den Kern eingeleitete Kräfte lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn das Blokkierelement in Blockierstellung einen an dem Gehäuse anliegenden Anschlag aufweist. Damit werden die in den Kern eingeleiteten und über den Sperrriegel auf das Blokkierelement übertragenden Kräfte an dem Gehäuse abgestützt. Weiterhin kann der Anschlag zur Begrenzung der Bewegung des Blockierelements durch den elektromotorischen Antrieb dienen.A movement of the blocking element in the blocking position by high forces introduced into the core can be according to another advantageous development simply avoid the invention when the blocking element in Blockierstellung a voltage applied to the housing Stop has. This will be the core introduced and over the locking bar on the blocking element transmitted forces supported on the housing. Furthermore, the stop for limiting the Movement of the blocking element by the electromotive Drive serve.

Der elektromotorische Antrieb könnte beispielsweise dauerhaft bestromt werden, wenn das Blockierelement von einer Stellung in die andere Stellung bewegt werden soll. Die Bewegung des Blockierelementes könnte über Endschalter überwacht werden. Dies erfordert jedoch einen hohen konstruktiven Aufwand. Der erfindungsgemäße Schließzylinder gestaltet sich jedoch konstruktiv besonders einfach durch eine elektronische Steuereinrichtung mit einem Impulsgeber zur Erzeugung eines Steuerimpulses für den elektromotorischen Antrieb. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass bei in der Bewegung blokkiertem Blockierelement eine dauerhafte Bestromung des elektromotorischen Antriebs vermieden wird. Eine Blockierung der Bewegung des Blockierelements kann beispielsweise entstehen, wenn der Kern sich nicht in der Nullstellung befindet und die Bewegung des Blockierelementes in die Blockierstellung zeitabhängig erfolgen soll.The electric motor drive could, for example, permanently be energized when the blocking element of a Position to be moved to the other position. The movement of the blocking element could be via limit switches be monitored. However, this requires a high constructive effort. The lock cylinder according to the invention However, it is structurally very simple by an electronic control device with a pulse generator for generating a control pulse for the electromotive drive. Another advantage of this Design is that when in motion blocked Blocking a permanent energization of the electric motor drive is avoided. A blockage the movement of the blocking element can, for example arise when the core is not in the zero position is located and the movement of the blocking element in the blocking position is to be time-dependent.

Das Blockierelement lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung durch den elektromotorischen Antrieb einfach in seine Freigabestellung bewegen, wenn das in Freigabestellung befindliche Blokkierelement einen an dem Gehäuse anliegenden Anschlag hat. Hierdurch werden aufwändig zu montierende Endschalter vermieden.The blocking element can be according to another advantageous Development of the invention by the electromotive Simply move the drive to its release position, when the blocking element is in the release position a voltage applied to the housing stop Has. As a result, be complicated to install limit switch avoided.

Figur 2 zeigt in einer Schnittdarstellung durch den Schließzylinder aus Figur 1 entlang der Linie II - II, dass das Blockierelement 14 unrund gestaltet ist und zwei Anschläge 18, 19 aufweist, mit denen es sich in zwei Endstellungen an dem Gehäuse 1 abstützt. In der dargestellten Endstellung hat das Blockierelement 14 einen Abstand zu dem Sperrriegel 8 und befindet sich damit in einer Freigabestellung. Dreht man das Blockierelement 14 gegen den Uhrzeigersinn, bis der andere Anschlag 19 gegen das Gehäuse 1 gelangt, steht das Blockierelement 14 unmittelbar dem als Blattfeder ausgebildeten Federelement 10 vor und verhindert damit ein Herausbewegen des Sperrriegels 8 aus der Ausnehmung 11 des Kerns 2. Damit ist die Bewegung des Kerns 2 gegenüber dem Gehäuse 1 blockiert und der Schließzylinder befindet sich in einer Verriegelungsstellung.Figure 2 shows in a sectional view through the Lock cylinder of Figure 1 along the line II - II, that the blocking element 14 is out of round and two Stops 18, 19, with which it is in two end positions is supported on the housing 1. In the illustrated End position, the blocking element 14 has a distance to the locking bar 8 and is thus in one Release position. Turning the blocking element 14 against clockwise until the other stop 19 against the Housing 1 passes, the blocking element 14 is immediately the spring element 10 designed as a leaf spring and thus prevents it from moving out of the locking bolt. 8 from the recess 11 of the core 2. This is the movement the core 2 is blocked relative to the housing 1 and the Locking cylinder is in a locking position.

Figur 3 zeigt eine weitere Ausführungsform des Schließzylinders, welcher sich von dem aus Figur 1 vor allem dadurch unterscheidet, dass der Sperrriegel 8 über der von dem als Blattfeder ausgebildeten Federelement 10 gehaltenen Kugel 9 ein Sperrglied 20 hat. Das Sperrglied 20 ist in einer den Kern 2 durchdringenden kanalförmigen Ausnehmung 21 verschieblich angeordnet und weist eine dem Durchmesser des Kerns 2 entsprechende Länge auf. Das Sperrglied 20 setzt sich aus einem in der Ausnehmung 21 angeordneten Bolzen 22 und einer in eine zweite Ausnehmung 23 des Gehäuses 1 eindringenden zweiten Kugel 24 zusammen.FIG. 3 shows a further embodiment of the lock cylinder, which differs from that of Figure 1, especially by it distinguishes that the locking bar 8 on the of held as a leaf spring spring element 10 held Ball 9 has a locking member 20. The locking member 20 is in a core 2 penetrating channel-shaped recess 21 slidably disposed and has a the Diameter of the core 2 corresponding length. The Locking member 20 is composed of a in the recess 21st arranged bolts 22 and one in a second recess 23 of the housing 1 penetrating second ball 24 together.

Figur 4 zeigt in einer Schnittdarstellung durch den Schließzylinder aus Figur 3 entlang der Linie IV -IV, dass die zweite Ausnehmung 23 des Gehäuses 1 dachförmig gestaltet ist. Bei einer Drehung des Kerns 2 wird die zweite Kugel 24 gegen den Bolzen 22 und dieser gegen die von dem Federelement 10 gehaltene Kugel 9 gedrückt. Das Blockierelement 14 ist bei der Bewegung in die Blockierstellung dargestellt, in der ein Herausbewegen der von dem Federelement 10 gehaltenen Kugel 9 aus dem Kern 2 verhindert wird. Damit wird der Kern 2 in Verriegelungsstellung des Schließzylinders durch die beiden in der Trennebene zwischen Kern 2 und Gehäuse 1 befindlichen Kugeln 9, 24 an zwei Stellen formschlüssig mit dem Gehäuse 1 verbunden. Ansonsten ist der Schließzylinder nach den Figuren 3 und 4 wie der aus den Figuren 1 und 2 aufgebaut.Figure 4 shows in a sectional view through the Lock cylinder of Figure 3 along the line IV -IV, that the second recess 23 of the housing 1 roof-shaped is designed. Upon rotation of the core 2, the second ball 24 against the pin 22 and this against the pressed by the spring element 10 ball 9 pressed. The Blocking element 14 is in the movement in the blocking position shown in which a move out of the spring element 10 held ball 9 of the core. 2 is prevented. This is the core 2 in the locked position of the lock cylinder through the two in the Parting plane between core 2 and housing 1 balls 9, 24 in two places form-fitting with the housing 1 connected. Otherwise, the lock cylinder after the Figures 3 and 4 as that of Figures 1 and 2 constructed.
