Dabei sind als Kraftübertragungselemente zumindest zwei jeweils als Wälzkörper ausgeführte, aufeinander abrollende Kraftübertragungselemente vorgesehen, wobei eines dieser Kraftübertragungselemente durch eine jeweilige Beaufschlagung durch das aktivierte Stellglied zur Überführung der Kraftübertragungselemente in deren Verriegelungsposition relativ zu dem wenigstens einen unmittelbar angrenzenden weiteren Kraftübertragungselement versetzt positioniert ist, so dass eine sich in Bewegungsrichtung des Stellgliedes erstreckende Kraftkomponente erzeugt wird und das durch das Stellglied beaufschlagbare Kraftübertragungselement bei deaktiviertem Stellglied zur Freigabe der Verriegelung zumindest im Wesentlichen in Bewegungsrichtung des Stellgliedes ausweichen kann. Erfindungsgemäß weist das Verriegelungssystem nur drei jeweils als aufeinander abrollende Wälzkörper ausgeführte Kraftübertragungselemente auf.The locking system according to the invention, in particular locking system of a door opener or lock, comprising a housing, a cooperating with a latch or the like, in particular pivotally mounted in the housing lock, an actuator and arranged between the lock and the actuator power transmission elements in the housing between a Locking position in which they lock the lock, and are mounted displaceably in a release position in which they release the lock.

Damit ist bei weiterhin relativ begrenzter Anzahl von Bauelementen und entsprechend kostengünstigem Aufbau die Funktionssicherheit entsprechend erhöht. Aufgrund dieser Ausbildung ergibt sich ein relativ einfacher, kompakter und entsprechend kostengünstiger Aufbau. Zudem gewährleistet das erfindungsgemäße Verriegelungssystem nicht nur eine höhere Funktionssicherheit, es weist auch eine längere Lebensdauer auf. Die aufgebrachten Kräfte sind einfach berechenbar und damit beherrschbar. Als Wälzkörper können verschleißfeste Normteile eingesetzt werden, womit sich die Lebensdauer des Verriegelungssystems entsprechend erhöht. Mit der höheren Genauigkeit und Oberflächengüte solcher Normalteile ergibt sich entsprechend auch wieder eine höhere Funktionssicherheit. Es sind insgesamt relativ wenige Bauteile erforderlich. Es ergeben sich insgesamt geringere Fertigungstoleranzen. Zudem ist das kostengünstig herstellbare erfindungsgemäße Verriegelungssystem universell einsetzbar.Thus, the functional reliability is increased accordingly in still relatively limited number of components and correspondingly inexpensive construction. Due to this design results in a relatively simple, compact and correspondingly inexpensive construction. In addition, the locking system according to the invention not only ensures a higher reliability, it also has a longer life. The applied forces are easy to calculate and therefore manageable. As rolling elements wear-resistant standard parts can be used, which increases the life of the locking system accordingly. With the higher accuracy and surface quality of such normal parts results in accordance with again higher reliability. There are a total of relatively few components required. This results in lower overall manufacturing tolerances. In addition, the cost-producible locking system according to the invention is universally applicable.
Das Verriegelungssystem ist darüber hinaus relativ reibungsarm, da das mechanische Zusammenwirken der Wälzkörper über Abrollbewegungen erfolgt und nahezu ausschließlich Rollreibungskräfte auftreten.The locking system is also relatively low friction, since the mechanical interaction of the rolling elements on rolling movements and occurs almost exclusively rolling friction forces.
In diesem Fall ist das durch das Stellglied beaufschlagbare Kraftübertragungselement bevorzugt zwischen den beiden unmittelbar angrenzenden weiteren Kraftübertragungselementen angeordnet.In this case, the force transmission element which can be acted upon by the actuator is preferably arranged between the two directly adjoining further force transmission elements.
Zweckmäßigerweise ist eines der beiden unmittelbar an das durch das Stellglied beaufschlagbare Kraftübertragungselement angrenzenden Kraftübertragungselemente zwischen dem durch das Stellglied beaufschlagbaren Kraftübertragungselement und der Verriegelung angeordnet.Conveniently, one of the two directly adjacent to the acted upon by the actuator force transmission element power transmission elements between the acted upon by the actuator force transmission element and the latch is arranged.
Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Verriegelungssystems sind die Kraftübertragungselemente jeweils als insbesondere gehärtete Stahlrollen ausgeführt. Mit solchen gehärteten Stahlrollen können für die Kraftübertragungselemente verschleißfeste Normteile eingesetzt werden, womit sich infolge der Genauigkeit und Oberflächengüte solcher Normteile eine höhere Funktionssicherheit und geringere Fertigungstoleranzen ergeben.According to a preferred practical embodiment of the locking system according to the invention, the power transmission elements are each designed as a particular hardened steel rollers. With such hardened steel rollers wear-resistant standard parts can be used for the power transmission elements, which results in a higher reliability and lower manufacturing tolerances due to the accuracy and surface quality of such standard parts.

Alternativ oder zusätzlich kann das Stellglied jedoch beispielsweise auch ein elektromechanisches Betätigungselement, einen Elektromotor, ein hydraulisches Betätigungselement, ein pneumatisches Betätigungselement und/oder dergleichen umfassen.The actuator preferably comprises an electromagnet.

Die Verriegelung kann insbesondere einen um eine Achse schwenkbar am Gehäuse gelagerten Hebel, einen linear geführten Schieber oder dergleichen umfassen.In particular, the lock may comprise a lever mounted pivotably on the housing about an axis, a linearly guided slide or the like.
Gemäß einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Verriegelungssystems umfasst die Verriegelung eine insbesondere mit einer Schlossfalle zusammenwirkende Türöffnerfalle.According to an expedient practical embodiment of the locking system according to the invention, the locking device comprises a door-opener trap cooperating in particular with a lock latch.
Zudem ist von Vorteil, wenn die um eine Achse schwenkbar im Gehäuse gelagerte Verriegelung mit einem zur Schwenkachse exzentrischen Ansatz versehen ist, durch den das unmittelbar angrenzende Kraftübertragungselement mit einem jeweiligen Verschwenken der Verriegelung in deren Freigabeposition gegen das durch das Stellglied beaufschlagbare Kraftübertragungselement gedrückt wird, so dass das durch das Stellglied beaufschlagbare, relativ zum durch die Verriegelung beaufschlagbaren Kraftübertragungselement versetzt positionierte Kraftübertragungselement bei deaktiviertem Stellglied zumindest im Wesentlichen in Bewegungsrichtung des Stellglieds aus seiner Verriegelungsposition herausgedrängt wird. Dagegen ist die Verriegelung bei aktiviertem Stellglied durch die in ihrer Verriegelungsposition gehaltenen Kraftübertragungselemente daran gehindert, aus ihrer Verriegelungsposition in ihre Freigabeposition verschwenkt zu werden, da das vom aktivierten Stellglied beaufschlagte Kraftübertragungselement nicht mehr in Bewegungsrichtung des Stellglieds ausweichen kann und entsprechend das an die Verriegelung angrenzende Kraftübertragungselement die Verriegelung über deren exzentrischen Ansatz blockiert.In addition, it is advantageous if the pivotally mounted about an axis in the housing latch is provided with an eccentric to the pivot axis approach by which the immediately adjacent power transmission element is pressed with a respective pivoting of the lock in its release position against the acted upon by the actuator force transmission element, so in that the force transmission element which is acted upon by the actuator and displaced relative to the force transmission element which can be acted upon by the locking is forced out of its locking position, at least substantially in the direction of movement of the actuator, when the actuator is deactivated. In contrast, the lock is activated by the actuators held in its locking position from being pivoted from its locking position to its release position, since the acted upon by the activated actuator power transmission element can no longer escape in the direction of movement of the actuator and corresponding to the locking adjacent force transmission element the lock is blocked by its eccentric approach.
Dabei wird das unmittelbar an die Verriegelung angrenzende Kraftübertragungselement bei deaktiviertem Stellglied mit einem jeweiligen Verschwenken der Verriegelung in deren Freigabeposition durch deren exzentrischen Ansatz bevorzugt zumindest im Wesentlichen quer zur Bewegungsrichtung des Stellglieds gegen das durch das Stellglied beaufschlagte Kraftübertragungselement gedrückt.In this case, the immediately adjacent to the locking force transmission element is disabled actuator with a respective pivoting of the lock pressed in the release position by the eccentric approach preferably at least substantially transversely to the direction of movement of the actuator against the acted upon by the actuator force transmission element.
Zusätzlich oder anstelle des Stellglieds kann eine als Überlastsicherung dienende Federeinheit oder dergleichen vorgesehen sein, durch die das Kraftübertragungselement federnd in seiner Verriegelungsposition gehalten ist.In addition to or instead of the actuator may be provided as overload protection spring unit or the like, through which the force transmission element is resiliently held in its locking position.
Von Vorteil ist zudem, wenn sich das durch das Stellglied beaufschlagbare Kraftübertragungselement bei ihre Verriegelungsposition einnehmenden Kraftübertragungselementen auf einem Absatz des Gehäuses abstützt und dadurch relativ zu dem wenigstens einen unmittelbar angrenzenden weiteren Kraftübertragungselement versetzt positioniert ist.It is also advantageous if the acted upon by the actuator force transmission element is supported at their locking position engaging force transmission elements on a shoulder of the housing and thereby positioned relative to the at least one immediately adjacent further force transmission element.

Das jeweilige erfindungsgemäße Verriegelungssystem zeichnet sich sowohl durch eine kompakte Bauweise als auch eine hohe Funktionssicherheit aus. Die aufzubringenden Kräfte sind leicht berechenbar und damit beherrschbar. Mit den gehärteten Stahlrollen als Kraftübertragungselemente können verschleißfeste Normteile eingesetzt werden. Durch die Genauigkeit und Oberflächengüte solcher Normteile ergibt sich eine relativ hohe Funktionssicherheit. Darüber hinaus zeichnet sich das erfindungsgemäße Verriegelungssystem 10 durch eine geringe Anzahl von Bauteilen aus, womit das System insbesondere kostengünstiger herstellbar ist. Zudem ergeben sich geringere Fertigungstoleranzen. Schließlich ist das relativ kostengünstig herstellbare erfindungsgemäße Verriegelungssystem 10 universell einsetzbar.The respective locking system according to the invention is characterized both by a compact design and high reliability. The applied forces are easy to calculate and thus manageable. Wear-resistant standard parts can be used with the hardened steel rollers as power transmission elements. The accuracy and surface quality of such standard parts results in a relatively high reliability. In addition, the locking
