Description
Die Erfindung betrifft ein Kupplungssystem für ein Schloss.The invention relates to a coupling system for a lock.
Aus dem Stand der Technik sind Schlosskästen mit einer Schlossnuss bekannt, die über eine mechanische Handhabe, die in der Regel über einen Vierkantstift mit der Schlossnuss verbunden ist, betätigt werden. Die Betätigung der Handhabe, beispielsweise eines Türdrückers, bewirkt eine Drehbewegung der Schlossnuss und löst das Zurückfahren eines Verriegelungselements, beispielsweise der Falle des Schlosses, aus.Lock cases with a lock nut are known from the prior art, which are actuated by a mechanical handle, which is usually connected via a square pin with the lock nut. The actuation of the handle, such as a door handle, causes a rotational movement of the lock nut and triggers the return of a locking element, such as the case of the castle from.
Insbesondere für elektromechanische Schlösser ist es bekannt, die Schlossnuss nicht direkt mit dem Verriegelungselement zu verbinden, sondern ein schaltbares Kupplungssystem vorzusehen, welches durch ein elektromechanisches System, beispielsweise ein Relais, aktivierbar ist. Im offenen Zustand ist das Kupplungssystem ausgekuppelt, sodass eine Betätigung der Handhabe keine Betätigung des Verriegelungselements bewirkt. Im geschlossenen Zustand ist das Kupplungssystem eingekuppelt, sodass eine Betätigung der Handhabe eine Betätigung des Verriegelungselements bewirkt. Derartige elektromechanische Kupplungssysteme eignen sich insbesondere für die Verwendung in Gebäuden, unter anderem da nur geringe Energie benötigt wird, um das Relais zu aktivieren. Somit kann eine Energieversorgung durch Batterien erfolgen, wodurch auch die Nachrüstung bestehender Systeme in Gebäuden ermöglicht wird.In particular, for electromechanical locks, it is known not to connect the lock nut directly to the locking element, but to provide a switchable coupling system, which can be activated by an electromechanical system, such as a relay. In the open state, the coupling system is disengaged, so that actuation of the handle causes no actuation of the locking element. In the closed state, the coupling system is engaged, so that actuation of the handle causes actuation of the locking element. Such electromechanical coupling systems are particularly suitable for use in buildings, inter alia, since only low energy is needed to activate the relay. Thus, a power supply can be done by batteries, which also allows the retrofitting of existing systems in buildings.
Derartige Kupplungssysteme umfassen in der Regel ein drehbares äußeres Kupplungsteil und ein inneres Kupplungsteil, das im äußeren Kupplungsteil im Wesentlichen konzentrisch und gegenüber dem äußeren Kupplungsteil drehbar gelagert ist.Such coupling systems usually comprise a rotatable outer coupling part and an inner coupling part, which is mounted in the outer coupling part substantially concentric and rotatable relative to the outer coupling part.
Weiters ist ein, in der Regel elektromechanisch betätigbares, Kuppelelement vorgesehen, das dazu ausgeführt ist, in einem Ruhezustand die beiden Kupplungsteile gegeneinander drehbar zu lassen und in einem Arbeitszustand die beiden Kupplungsteile drehfest miteinander zu verbinden.Furthermore, a, usually electromechanically actuated, coupling element is provided, which is designed to let the two coupling parts against each other rotatable in a resting state and in a working state, the two coupling parts rotatably connected to each other.
Ein Problem derartiger bekannter Kupplungssysteme besteht darin, dass die Drehstellung der beiden im Wesentlichen konzentrisch angeordneten Kupplungsteile zueinander in der Ruhestellung nicht in jedem Schlosskasten eingehalten werden kann. Manche Schlosskästen erfordern zur Montage der Handhabe eine bestimmte Drehstellung der Kupplungsteile zueinander, sodass vor Montage nicht mit Sicherheit bestimmt werden kann, welche Drehstellung die beiden Kupplungsteile zueinander in der Ruhestellung einnehmen werden. Dadurch wird jedoch der sichere Eingriff des Kuppelelements in beide Kupplungsteile zur drehfesten Verbindung erschwert oder unmöglich gemacht. Als Abhilfe werden in der Praxis Zusatzteile eingesetzt, die eine Verdrehung der Ruhestellung der Kupplungsteile um einen bestimmten Drehwinkel, beispielsweise 2° oder 4°, in eine bestimmte Richtung ermöglichen. Der Einsatz dieser Zusatzteile ist jedoch umständlich und fehleranfällig, und soll deshalb in der Praxis vermieden werden.A problem of such known coupling systems is that the rotational position of the two substantially concentric coupling parts to each other in the rest position can not be met in each lock case. Some lock boxes require a certain rotational position of the coupling parts to each other for mounting the handle, so that it can not be determined with certainty before assembly, which rotational position the two coupling parts will occupy each other in the rest position. As a result, however, the secure engagement of the coupling element in both coupling parts for rotationally fixed connection is made difficult or impossible. As a remedy, additional parts are used in practice, which allow a rotation of the rest position of the coupling parts by a certain angle of rotation, for example 2 ° or 4 °, in a certain direction. However, the use of these additional parts is cumbersome and error-prone, and should therefore be avoided in practice.
Die Aufgabe der Erfindung besteht darin, ein Kupplungssystem zu schaffen, welches eine robuste drehfeste Verbindung der Kupplungsteile ohne Zusatzteile auch dann ermöglicht, wenn in der Ruhelage die beiden Kupplungsteile in einer variablen und nicht vorgesehenen Drehstellung zueinander stehen.The object of the invention is to provide a coupling system which allows a robust non-rotatable connection of the coupling parts without additional parts, even if in the rest position, the two coupling parts are in a variable and not provided rotational position to each other.

Insbesondere können das äußere und innere Kupplungsteil als Kupplungsrine ausgeführt sein. Es kann erfindungsgemäß aber ebenso vorgesehen sein, dass das äußere und innere Kupplungsteil eine elliptische oder rechteckige Form aufweisen.According to the invention it can be provided that the outer and inner coupling part are made substantially circular or substantially annular. In particular, the outer and inner coupling part may be designed as a coupling rine. However, it can also be provided according to the invention that the outer and inner coupling part have an elliptical or rectangular shape.
Erfindungsgemäß kann dazu vorgesehen sein, dass das Kuppelelement in einer Ausnehmung des inneren Kupplungsteils entlang einer ersten Achse linear verschiebbar gelagert ist, wobei zur Verschiebung ein, in einer umfangsseitigen Ausnehmung des äußeren Kupplungsteils entlang einer zweiten Achse linear verschiebbar gelagertes Betätigungselement vorgesehen ist. Dieses Betätigungselement kann insbesondere derart ausgeführt sein, dass es das Kuppelelement betätigen, also linear verschieben kann. Bei dem Betätigungselement kann es sich insbesondere um einen Stift handeln, der in einer umfangsseitigen Öffnung des äußeren Kupplungsteils gelagert ist und durch einen elektromechanischen Aktor, beispielsweise ein Relais oder ein mit einem Relais verbundenen Hebel, entlang seiner Längsrichtung verschoben werden kann.According to the invention it can be provided that the coupling element is mounted linearly displaceable in a recess of the inner coupling part along a first axis, wherein for displacement, a, in a circumferential recess of the outer coupling part along a second axis linearly displaceably mounted actuating element is provided. This actuating element can in particular be designed such that it can actuate the coupling element, ie can move linearly. The actuating element may in particular be a pin which is mounted in a peripheral opening of the outer coupling part and can be displaced along its longitudinal direction by an electromechanical actuator, for example a relay or a lever connected to a relay.
Erfindungsgemäß kann vorgesehen sein, dass am Kuppelelement ein Betätigungsbereich zur Betätigung durch das Betätigungselement und ein Verbindungsbereich zur kraft- oder formschlüssigen Verbindung mit einer am inneren Umfang des äußeren Kupplungsteils vorgesehenen Eingriffsfläche vorgesehen sind. Der Betätigungsbereich und der Verbindungsbereich des Kuppelelements können über einen Steg verbunden sein. Insbesondere kann vorgesehen sein, dass das Kuppelelement einstückig ausgeführt ist. Insbesondere kann weiters vorgesehen sein, dass der Verbindungsbereich und der Betätigungsbereich an entgegengesetzten Enden des Kuppelelements angeordnet sind.According to the invention it can be provided that the coupling element an operating area for actuation by the actuating element and a connection area for non-positive or positive connection with a provided on the inner circumference of the outer coupling part engagement surface are provided.

Dadurch wird erreicht, dass das Betätigungselement das Kuppelelement auch dann lateral verschieben, also betätigen kann, wenn die Verschiebungsachse des Kuppelelements und die Verschiebungsachse des Betätigungselements nicht kollinear zueinander ausgerichtet sind. Das Betätigungselement drückt dann zwar schräg auf das Kuppelelement, solange jedoch die Winkelabweichung nicht zu groß und die die Kraft des Betätigungselements stark genug ist, bewirkt dies dennoch eine Längsverschiebung des Kuppelelements.It is thereby achieved that the actuating element, the coupling element even then move laterally, so can operate when the displacement axis of the coupling element and the displacement axis of the actuating element are not aligned collinear with each other. Although the actuator then presses obliquely on the coupling element, but as long as the angle deviation is not too large and the force of the actuator is strong enough, this still causes a longitudinal displacement of the coupling element.
Erfindungsgemäß kann vorgesehen sein, dass der Verbindungsbereich und die Eingriffsfläche einen kreisabschnittförmigen Querschnitt aufweisen, wobei die Eingriffsfläche einen größeren Winkelbereich des inneren Umfangs des äußeren Kupplungsteils abdeckt, als der Verbindungsbereich. Dadurch wird bewirkt, dass der Verbindungsbereich auch dann in Verbindung mit der Eingriffsfläche bringbar ist, wenn die Verschiebungsachse des Kuppelelements und die Verschiebungsachse des Betätigungselements nicht kollinear, sondern in einem Winkel zueinander angeordnet sind.According to the invention, it can be provided that the connection region and the engagement surface have a circular section-shaped cross-section, wherein the engagement surface covers a larger angle range of the inner circumference of the outer coupling part than the connection region. This has the effect that the connection region can be brought into connection with the engagement surface even if the displacement axis of the coupling element and the displacement axis of the activation element are not arranged collinearly but at an angle to one another.
Erfindungsgemäß kann vorgesehen sein, dass der Verbindungsbereich und die Eingriffsfläche mit Rastelementen, insbesondere mit einer korrespondierenden Verzahnung, ausgeführt sind. Selbstverständlich kann auch eine rein kraftschlüssige Verbindung zwischen Verbindungsbereich und Eingriffsfläche vorgesehen sein.According to the invention, it can be provided that the connection region and the engagement surface are designed with latching elements, in particular with a corresponding toothing. Of course, a purely frictional connection between the connection area and the engagement surface can also be provided.
Erfindungsgemäß kann vorgesehen sein, dass der durch die Eingriffsfläche definierte Kreisabschnitt am inneren Umfang des äußeren Kupplungsteils einen Mittelpunktwinkel von 30° bis 90°, vorzugsweise etwa 60°, aufweist. Erfindungsgemäß kann weiters vorgesehen sein, dass der durch den Verbindungsbereich definierte Kreisabschnitt am äußeren Umfang des inneren Kupplungsteils einen Mittelpunktwinkel von 15° bis 45°, vorzugsweise etwa 30°, aufweist.According to the invention, it may be provided that the circular section defined by the engagement surface on the inner circumference of the outer coupling part has a center angle of 30 ° to 90 °, preferably about 60 °. According to the invention, it can further be provided that the circle section defined by the connection region has a midpoint angle of 15 ° to 45 °, preferably approximately 30 °, on the outer circumference of the inner coupling part.
Als Mittelpunktwinkel wird jener Winkel bezeichnet, den die Enden des jeweiligen umfangsseitigen Kreisabschnitts in Bezug auf den Mittelpunkt der Drehachse der Kupplungsteile definieren.The center angle is the angle defined by the ends of the respective circumferential circle section with respect to the center of the axis of rotation of the coupling parts.

Weitere erfindungsgemäße Merkmale ergeben sich aus den Ansprüchen, der Beschreibung des Ausführungsbeispiels und den Zeichnungen.Further features of the invention will become apparent from the claims, the description of the embodiment and the drawings.
Im Folgenden wird die Erfindung am Beispiel eines nicht ausschließlichen Ausführungsbeispiels näher erläutert.In the following, the invention will be explained in more detail using the example of a non-exclusive embodiment.
Das Kupplungssystem 1 umfasst den äußeren Kupplungsring 2, den inneren Kupplungsring 3 sowie ein Kuppelelement 4. Der äußere Kupplungsring 2 und der innere Kupplungsring 3 sind im Wesentlichen konzentrisch angeordnet und um dieselbe Drehachse drehbar in einem (nicht dargestellten) Gehäuse gelagert.The
Im inneren Kupplungsring 3 ist eine, normal auf die Drehachse orientierte, Ausnehmung 10 vorgesehen. In dieser Ausnehmung 10 ist ein Kuppelelement 4 angeordnet, welches entlang seiner Längsachse 5 verschiebbar ist, wie durch den Doppelpfeil angedeutet ist. Das Kuppelelement 4 ist jedoch bezüglich Drehbewegungen formschlüssig in die Ausnehmung 10 eingebracht, sodass eine Verdrehung des Kuppelelements 4 relativ zum inneren Kupplungsring 3 nicht möglich ist. Ein (nicht dargestelltes) Rückstellelement 13 sorgt dafür, dass das Kuppelelement 4 nach einer Verschiebung entlang seiner Längsachse 5 wieder in die dargestellte Ruhelage bewegt wird.In the
Der äußere Kupplungsring 2 weist (nicht dargestellte) Verbindungsmittel auf, um mit einer ersten Handhabe zur Betätigung des Schlosses verbunden zu werden. Auch der innere Kupplungsring 3 weist (nicht dargestellte) Verbindungsmittel zur Verbindung mit einer zweiten Handhabe zur Betätigung des Schlosses auf.The
Das Kuppelelement 4 ist länglich und umfasst einen Betätigungsbereich 6 sowie einen gegenüber angeordneten Verbindungsbereich 7, die über einen Steg miteinander verbunden sind. Im vorliegenden Ausführungsbeispiel ist das Kuppelelement 4 einstückig, es sind aber auch Ausführungsformen der Erfindung vorgesehen, in denen das Kuppelelement 4 mehrstückig ist.The
Der Betätigungsbereich 6 des Kuppelelements 4 weist einen kreisabschnittförmigen Querschnitt auf, der bündig mit der äußeren Oberfläche des inneren Kupplungsrings 3 ausgeführt ist. Zur Aufnahme des Betätigungsbereichs 6 verfügt der innere Kupplungsring 3 über eine entsprechende Ausnehmung 10.
Beidseitig des Betätigungsbereichs 6 sorgen Vorsprünge am Kuppelelement 4 dafür, dass das Kuppelelement 4 nicht aus dem inneren Kupplungsring 3 herausgedrückt werden kann. Diese Vorsprünge wirken mit entsprechenden Anschlägen am inneren Umfang des inneren Kupplungsrings 3 formschlüssig zusammen, um diese Wirkung zu erzielen.The actuating
On both sides of the
Der Betätigungsbereich 6 des Kuppelelements 4 ragt durch eine Ausnehmung im Umfang des inneren Kupplungsrings 3 und schließt bündig mit dem äußeren Umfang des inneren Kupplungsrings 3 ab. Im Bereich dieser Ausnehmung befindet sich am Umfang des äußeren Kupplungsring 2 eine Öffnung, in der ein verschiebbares Betätigungselement 8, im vorliegenden Ausführungsbeispiel in Form eines verschiebbaren Stiftes, gelagert ist.The
Das Betätigungselement 8 befindet sich in der dargestellten ersten Ruhelage des Kupplungssystems 1 derart gegenüber dem Kuppelelement 4 angeordnet, dass sowohl das Betätigungselement 8, als auch das Kuppelelement 4 entlang im Wesentlichen derselben Längsachse 5 verschiebbar sind, wie durch die beiden Doppelpfeile angedeutet ist.The
Dadurch wird bewirkt, dass das Betätigungselement 8 das Kuppelelement 4 entlang der Längsachse 5 gegen die Rückstellkraft des (nicht dargestellten) Rückstellelements 13 verschieben kann.This causes the
Am gegenüberliegenden Ende des Kuppelelements 4 befindet sich ein Verbindungsbereich 7, der in einer weiteren umfangsseitigen Ausnehmung des inneren Kupplungsrings 3 geführt ist. Der Verbindungsbereich 7 ist zum formschlüssigen Eingriff in eine Eingriffsfläche 9 am inneren Umfang des äußeren Kupplungsrings 2 ausgeführt. Zu diesem Zweck weist sowohl der Verbindungsbereich 7, als auch die Eingriffsfläche 9 eine korrespondierende Verzahnung auf. In der dargestellten ersten Ruhelage des Kupplungssystems 1 befindet sich der Verbindungsbereich 7 jedoch nicht im Eingriff mit der Eingriffsfläche 9.At the opposite end of the
In diesem zweiten Ruhezustand ist die Längsachse 5 des Betätigungselements 8 nicht kollinear mit der Längsachse des Kupplungselements 4, sondern diese Achsen sind in einem Winkel zueinander angeordnet.
In this second resting state, the
Auch in diesem zweiten Ruhezustand bewirkt jedoch eine Verschiebung des Betätigungselements 8 entlang der Achse 5 eine Längsverschiebung des Kuppelelements 4, sodass auch in dieser verdrehten Stellung eine formschlüssige Kupplung des äußeren Kupplungsrings 2 mit dem inneren Kupplungsring 3 bewirkt werden kann.However, even in this second resting state, a displacement of the
Zu diesem Zweck weist der Betätigungsbereich 6 des Kuppelelements 4 einen kreisabschnittförmigen Querschnitt auf, der einen größeren Winkelbereich des inneren Umfangs des äußeren Kupplungsrings 2 abdeckt, als das Betätigungselement 8. Entsprechend ist auch die Ausnehmung 10 zur Aufnahme des Betätigungsbereichs 6 im inneren Kupplungsring 3 größer als die Ausnehmung zur Aufnahme des Betätigungselements 8 im äußeren Kupplungsring 2.For this purpose, the actuating
Auf der gegenüberliegenden Seite ist sowohl der Verbindungsbereich 7 des Kuppelelements 4, als auch die Eingriffsfläche 9 des äußeren Kupplungsrings 2 mit einem kreisabschnittförmigen Querschnitt ausgeführt, wobei jedoch die Eingriffsfläche 9 einen größeren Winkelbereich des inneren Umfangs des äußeren Kupplungsrings 2 abdeckt, als der Verbindungsbereich 7. Dadurch wird erreicht, dass der Verbindungsbereich 7 auch dann in formschlüssige Verbindung mit der Eingriffsfläche 9 treten kann, wenn die Längsachse 5 des Betätigungselements 8 nicht kollinear mit der Längsachse des Kuppelelements 4 liegt, und die Längsverschiebung des Betätigungselements 8 somit eine dazu in einem Winkel stehende Verschiebung des Kuppelelements 4 bewirkt, wie durch die beiden Doppelpfeile angedeutet ist.On the opposite side, both the connecting
Im vorliegenden Ausführungsbeispiel ist vorgesehen, dass der durch die Eingriffsfläche 9 definierte Kreisabschnitt am inneren Umfang des äußeren Kupplungsrings 2 einen Mittelpunktswinkel von etwa 60° aufweist. Ebenso ist vorgesehen, dass der durch den Betätigungsbereich 6 am äußeren Umfang des inneren Kupplungsrings 3 definierte Kreisabschnitt einen Mittelpunktswinkel von etwa 24° aufweist. Selbstverständlich sind auch Ausführungsformen mit anderen Werten der Mittelpunktswinkel erfindungsgemäß vorgesehen.In the present exemplary embodiment, it is provided that the circular section defined by the
Sobald das Betätigungselement 8 zurück bewegt wird, wird auch das Kuppelelement 4 durch das Rückstellelement 13 in seine Ruhelage zurück bewegt, sodass die Kupplung des äußeren Kupplungsrings 2 mit dem inneren Kupplungsring 3 wieder aufgehoben ist.As soon as the
Im vorliegenden Ausführungsbeispiel ist sowohl der innere Kupplungsring 3 als auch der äußere Kupplungsring 2 mit einem Verbindungsbereich zur Aufnahme einer ersten bzw. zweiten Handhabe zur Betätigung des Schlosses ausgeführt.In the present embodiment, both the
