- a cylinder lock is out of the FR 2 866 045 A1 previously known.
- a on a drive shaft which forms the cylinder core of a lock cylinder, seated rotary knob is described, whose end face is designed as a push button.
- This push button can be displaced against the restoring force of a spring in the direction of the axis of rotation of the rotary knob in order to achieve a rotational drive between a closing member and the rotary knob.
- the WO 2005/019570 A1 shows an element for opening and / or closing doors, gates or windows.
- the CH 334964 describes a rotary knob which can be coupled with an output element. Again, a push button must be moved in the axial direction of the axis of rotation.
- the DE 199 57 697 C2 describes a pusher element for use as a pawl in a door handle set, in which the rotary knob must be displaced in the direction of the axis of rotation in order to connect it to a shaft connected to a closing member.

- a clutch is provided within the core bore of the cylinder housing 1. This consists of two coupling elements 4, 5, which have on their mutually facing end faces coupling profiles which engage each other in a corresponding axial displacement of the coupling elements 4, 5, so that then the coupling elements 4, 5 occupy a rotational driving position.
- a clutch spring 17 is tensioned, which normally hold the two coupling elements 4, 5 in a distance position, in which the coupling profiles do not interlock, so that in this separate position of the rotary knob 3 can be rotated without the closing member 2 rotates.
- the rotary knob 3 has an axial cavity into which a shaft portion 9, which forms a plunger, is immersed.
- the plunger 9 is inserted in a cavity of a cylinder core 26, which is rotatably mounted within a core bore of the cylinder housing 1 and which supports a coupling element 5.

Description
Die Erfindung betrifft einen Betätigungsknauf insbesondere für ein Zylinderschloss mit einem Gehäuse welches einen Drehknauf lagert, mit einer zwei Kupplungselemente aufweisenden Kupplung, die durch gleichzeitige Verlagerung eines ersten und eines zweiten Druckknopfes von einer Normalstellung, in der die Kupplungselemente voneinander getrennt sind, in eine Drehmitnahmestellung bringbar sind, in der die Kupplungselemente in einem Eingriff zueinander stehen.The invention relates to an actuating knob, in particular for a cylinder lock with a housing which supports a knob, with a coupling having two coupling elements, which can be brought by simultaneous displacement of a first and a second push button from a normal position in which the coupling elements are separated from each other in a rotational driving position are in which the coupling elements are in engagement with each other.
Die Erfindung betrifft darüber hinaus ein Schließzylinderschloss mit einem derartigen Betätigungsknauf, der mittels der Kupplung in eine Drehmitnahmestellung mit einem Schließglied bringbar ist.The invention further relates to a lock cylinder lock with such an actuating knob, which can be brought by means of the clutch in a rotational driving position with a closing member.

Es wird als gebrauchsnachteilhaft angesehen, wenn bei einem Schließzylinder der Druckknopf auf der Stirnfläche des Drehknaufes sitzt. Bringt man den Druckknopf allerdings in die Mantelfläche des im Wesentlichen zylinderförmigen Drehknaufes, so besteht die Gefahr, dass der Schließzylinder mit der Schlingenöffnungsmethode geöffnet werden kann. Bei dieser Methode wird eine Schlinge von außen durch eine Öffnung des Türblatts eingeführt, um den Drehknauf gelegt, so dass durch Zug an einem Ende der Schlinge der Drehknauf zum Öffnen der Tür gedreht werden kann. Ein auf der Mantelfläche des Drehknaufs angeordneter Druckknopf könnte bei dieser Methode von der Schlinge derart verlagert werden, dass die beiden Kupplungselemente in einen Drehmitnahmeeingriff treten.It is considered to be disadvantageous in terms of use if, in the case of a lock cylinder, the push button is seated on the end face of the rotary knob. However, if you bring the push button in the lateral surface of the substantially cylindrical rotary knob, so there is a risk that the lock cylinder can be opened with the loop opening method. In this method, a loop is inserted from the outside through an opening of the door leaf, placed around the knob, so that by pulling on one end of the loop, the knob can be rotated to open the door. A arranged on the lateral surface of the knob push button could be moved in this method of the loop such that the two coupling elements enter into a rotary driving engagement.
Der Erfindung liegt die Aufgabe zu Grunde, einen Betätigungsknauf gebrauchsvorteilhaft weiterzubilden und einen Schließzylinder anzugeben, dessen Aufsperrsicherheit weiter erhöht worden ist.The invention is based on the object to further develop an operating knob advantageous for use and to provide a lock cylinder, the Aufsperrsicherheit has been further increased.
Zur Lösung dieser Aufgabe wird ein Betätigungsknauf mit sämtlichen Merkmalen des Anspruchs 1 vorgeschlagen. In den abhängigen Ansprüchen sind bevorzugte Weiterbildungen ausgeführt.To solve this problem, an actuating knob with all the features of
Wesentlich ist, dass zwei Druckknöpfe vorgeschlagen sind, die gleichzeitig zu betätigen sind, um die beiden Kupplungselemente in eine Drehmitnahmestellung zueinander zu bringen. Erfindungsgemäß ist der erste Druckknopf mit dem zweiten Druckknopf derart mit einem Bewegungsumlenkglied getriebeverbunden, dass die beiden Drehmitnahmestellungen der beiden Kupplungselement nur nach Verlagerung beider Druckknöpfe erreichbar ist. Hierzu ist das Bewegungsumlenkglied sowohl in Betätigungsrichtung der beiden Druckknöpfe als auch in Richtung der Drehachse der Betätigungshandhabe verlagerbar. In einer Normalstellung werden die beiden Kupplungselemente von einer Kupplungsfeder in einer Getrenntstellung gehalten. Um die beiden Kupplungselemente von der Getrenntstellung in eine Drehmitnahmestellung zu bringen, in der Kupplungsvorsprünge der beiden Kupplungselemente ineinander greifen, müssen beide Druckknöpfe verlagert sein. Es besteht zwischen den beiden Druckknöpfen somit eine logische UND-Verknüpfung. Beide Druckknöpfe werden vorzugsweise von der Kupplungsfeder in einer Normalstellung gehalten. Sie können durch Druck auf ein Betätigungsende in eine Betätigungsstellung verlagert werden. Die Getriebeverbindung zu zumindest einem der Kupplungselemente ist dabei so ausgebildet, dass beide Druckknöpfe in ihre Betätigungsstellung verlagert sein müssen, damit die Kupplungselemente ihre Drehmitnahmestellung erreichen. Dies erfolgt gegen die Rückstellkraft der Kupplungsfeder. Die Verlagerungsrichtung der beiden Druckknöpfe ist bevorzugt im Wesentlichen quer zur Drehachse des Drehknaufes. Die Druckknöpfe sind somit der Umfangsmantelfläche des Drehknaufs zugeordnet. Es ist ferner bevorzugt vorgesehen, dass die beiden Druckknöpfe zum Erreichen der Drehmitnahmestellung aufeinander zu verlagert werden müssen. Konstruktiv ist die Getriebeverbindung derart ausgebildet, dass die Druckknöpfe mit einem Bewegungsumlenkglied zusammenwirken. Dieses Bewegungsumlenkglied kann sich innerhalb des Drehknaufes sowohl in Verlagerungsrichtung der beiden Druckknöpfe als auch in Verlagerungsrichtung eines der Kupplungselemente verlagern. Das Bewegungsumlenkglied kann schwimmend in einer Aufnahmekammer des Drehknaufes gelagert sein. Es ist aber auch vorgesehen, dass das Bewegungsumlenkglied schwenkbar dort angeordnet ist. Es kann mit einem Stößel zusammenwirken, um eines der Kupplungselemente zu verlagern. Der Stößel kann Teil einer Antriebswelle sein, mit der das Schließglied drehangetrieben wird. Das Bewegungsübertragungsglied kann eine Kugel, ein Gleitstück oder ein Schwenkhebel sein. Der Schwenkhebel kann schwenkbar am Stößel angelenkt sein. Zufolge dieser Ausgestaltung ist die Möglichkeit, einen mit einem Innendrehknauf ausgestatteten Schließzylinder von der Türaußenseite mit Hilfe der Schlingenöffnungsmethode zu drehen deutlich erschwert. Mit der Schlinge muss nicht nur ein einzelner Druckknopf von einer Normalstellung in eine Betätigungsstellung verlagert werden. Es müssen vielmehr beide Druckknöpfe gleichzeitig jeweils von ihrer Normalstellung in die Betätigungsstellung verlagert werden. Wird nur ein Druckknopf in die Betätigungsstellung verlagert, wird zwar das Bewegungsumlenkglied in seiner Höhlung des Drehknaufes verlagert. Es wird aber nur in Richtung der Verlagerungsrichtung des Druckknopfes verlagert. Erst wenn der zweite Druckknopf zusätzlich verlagert wird, was zeitlich später passieren kann, wird das Bewegungsumlenkglied auch in Achsrichtung des Stößels also in der Richtung der Drehachse des Drehknaufes verlagert, um die Kupplung in eine Drehmitnahmestellung zu bringen. In einer bevorzugten Ausgestaltung ist jedoch vorgesehen, dass bei der Verlagerung lediglich eines der Druckknöpfe das Bewegungsübertragungsglied auch in Achsrichtung des Stößels verlagert wird, so dass die Kupplungsfeder geringfügig gespannt wird. Die Kupplungselemente werden dabei zwar aufeinander zu verlagert jedoch nicht bis in ihre Eingriffsstellung. Diese Variante hat zur Folge, dass mit nur einer Feder, nämlich der Kupplungsfeder, nicht nur die Kupplungselemente auf Distanz gehalten werden, sondern dass mit dieser Feder auch beide Druckknöpfe in ihrer Normalstellung gehalten werden.It is essential that two push buttons are proposed to be operated simultaneously to bring the two coupling elements in a rotational drive position to each other. According to the invention, the first push-button with the second push-button is gear-connected to a movement deflecting member in such a way that the two rotational driving positions of the two coupling elements can only be achieved after shifting both pushbuttons. For this purpose, the Bewegungsumlenkglied is displaceable both in the direction of actuation of the two push buttons and in the direction of the axis of rotation of the actuating handle. In a normal position, the two coupling elements are held by a clutch spring in a separate position. To bring the two coupling elements of the separate position in a rotational drive position, engage in the coupling projections of the two coupling elements, both push buttons must be displaced. There is thus a logical AND connection between the two push buttons. Both push buttons are preferably held by the clutch spring in a normal position. They can be moved by pressure on an actuating end in an operating position. The gear connection to at least one of the coupling elements is designed so that both push buttons must be displaced in their operating position, so that the coupling elements reach their rotational driving position. This is done against the restoring force of the clutch spring. The direction of displacement of the two push buttons is preferably substantially transverse to the axis of rotation of the rotary knob. The push buttons are thus assigned to the peripheral surface of the rotary knob. It is further preferably provided that the two push buttons must be moved towards each other to reach the rotational driving position. Constructively, the transmission connection is designed such that the push buttons cooperate with a Bewegungsumlenkglied. This Bewegungsumlenkglied can be within the rotary knob both in the direction of displacement of the two Shift push buttons as well as in the direction of displacement of one of the coupling elements. The Bewegungsumlenkglied can be stored floating in a receiving chamber of the rotary knob. But it is also envisaged that the Bewegungsumlenkglied is pivotally arranged there. It can interact with a plunger to displace one of the coupling elements. The plunger may be part of a drive shaft with which the closing member is rotationally driven. The motion transmitting member may be a ball, a slider or a pivot lever. The pivot lever may be pivotally hinged to the plunger. According to this embodiment, the ability to turn a lock cylinder equipped with an inside knob from the outside of the door by means of the loop opening method is made much more difficult. With the sling not only a single push button must be moved from a normal position to an operating position. Rather, both pushbuttons must be displaced simultaneously from their normal position to the actuating position. If only one push button is displaced into the actuated position, the movement deflecting element is displaced in its cavity of the rotary knob. But it is only shifted in the direction of the displacement direction of the push button. Only when the second push button is additionally displaced, which can happen later in time, the Bewegungsumlenkglied is thus displaced in the axial direction of the plunger in the direction of the axis of rotation of the rotary knob to bring the clutch in a rotational driving position. In a preferred embodiment, however, it is provided that in the displacement of only one of the push buttons, the motion transmission member is displaced in the axial direction of the plunger, so that the clutch spring is slightly tensioned. Although the coupling elements are displaced towards each other but not in their engaged position. This variant has the consequence that with only one spring, namely the clutch spring, not only the coupling elements are kept at a distance, but that with this spring both snaps are held in their normal position.
In einer Weiterbildung der Erfindung, die eigenständigen Charakter hat, also grundsätzlich nicht erfordert, dass zwei Druckknöpfe vorhanden sind, ist vorgesehen, dass der Druckknopf in einer Mulde angeordnet ist. Diese Mulde weist einen Muldenrand auf. Um die Kupplungsstellung zu erreichen, muss das Betätigungsende des Druckknopfes bis unter das tiefste Niveau des Muldenrandes gebracht werden. Mit dieser konstruktiven Lehre wird ebenfalls die Aufsperrsicherheit erhöht, da eine zum Drehen des Drehknaufs verwendete Schlinge zwar den Druckknopf in seiner Betätigungsrichtung verlagern kann. Die Schlinge ist jedoch nur in der Lage, das Betätigungsende des Druckknopfes bis auf das tiefste Niveau des Muldenrandes zu senken. Dies reicht aber nicht aus, um die Kupplungselemente von ihrer Getrenntstellung in ihre Drehmitnahmestellung zu bringen. Hierzu muss der Druckknopf tiefer in die Mulde hineinverlagert werden. Auch bei dieser Lösung ist es von Vorteil, wenn zwei Druckknöpfe vorhanden sind, die insbesondere in diametral einander zugeordneten Lagerbohrungen des Drehknaufes gelagert sind. Dies erfolgt vorzugsweise anschlagsbegrenzt. Zur Anschlagsbegrenzung können Fesselungsmittel vorgesehen sein, die ringförmig oder gabelartig ausgebildet sind. Diese greifen in den durchmesserverminderten Abschnitt des Drehknaufes ein. Auch hier kann eine Kupplungsfeder vorgesehen sein, die die Kupplungselemente in einer Getrenntstellung halten und darüber hinaus auch den Druckknopf beziehungsweise zwei Druckknöpfe in ihrer Normalstellung halten. Bei der Verlagerung des mindestens einen Druckknopfes wird diese Kupplungsfeder gespannt.In one embodiment of the invention, which has independent character, so basically does not require that two push buttons are present, it is provided that the push button is arranged in a trough. This trough has a trough edge. In order to reach the coupling position, the operating end of the push button must be brought to below the lowest level of the trough edge. With this constructive teaching the unlocking security is also increased, since a sling used to rotate the knob while the push button can shift in its direction of actuation. However, the loop is only able to lower the operating end of the push button to the lowest level of the trough edge. However, this is not enough to bring the coupling elements of their separate position in its rotational driving position. For this purpose, the push button must be moved deeper into the trough. Also in this solution, it is advantageous if two push buttons are present, which are mounted in particular in diametrically associated bearing bores of the rotary knob. This is preferably stop limited. To stop limit captive means may be provided which are formed annular or fork-like. These engage in the diameter-reduced portion of the knob. Again, a clutch spring may be provided which hold the coupling elements in a separate position and also hold the push button or two push buttons in their normal position. When shifting the at least one push button, this clutch spring is tensioned.

Der erfindungsgemäße Schließzylinder besitzt ein Zylindergehäuse 1, welches einen Flanschabschnitt und einen Zylinderkernabschnitt aufweist. Das Zylindergehäuse 1 ist in eine Profilöffnung eines Einsteckschlosses einsteckbar. Auf einer Seite des Zylindergehäuses ist ein Zylinderkern vorgesehen, der eine Schlüsseleinstecköffnung aufweist, in die ein Schlüssel eingesteckt werden kann, um den Zylinderkern drehen zu können. Dieser Zylinderkern ist bei eingestecktem Schlüssel mit einem Schließglied 2 gekuppelt, welches einen Schließmechanismus im Einsteckschloss betätigen kann. In den Zeichnungen ist dieser schlüsselbetätigbare Zylinderkern nicht dargestellt. Im eingebauten Zustand weist dieser Abschnitt des Zylindergehäuses nach außen.The lock cylinder according to the invention has a
Türinnenseitig trägt das Zylindergehäuse einen Drehknauf 3. Der Drehknauf 3 besitzt zumindest einen Druckknopf 6. In den Ausführungsbeispielen sind zwei Druckknöpfe 6, 7 vorgesehen. Durch Druck auf den Druckknopf 6 kann der Drehknauf 3 in eine drehfeste Verbindung zum Schließglied 2 gebracht werden, so dass durch die Drehung des Drehknaufes 3 das Schließglied 2 von der Innenseite her gedreht werden kann. Ohne Druckknopfbetätigung ist der Drehknauf 3 nicht mit dem Schließglied 2 drehgekuppelt. Innerhalb der Kernbohrung des Zylindergehäuses 1 ist eine Kupplung vorgesehen. Diese besteht aus zwei Kupplungselementen 4, 5, die auf ihren einander zugewandten Stirnseiten Kupplungsprofile aufweisen, die bei einer entsprechenden Axialverlagerung der Kupplungselemente 4, 5 aufeinander zu ineinander greifen, so dass dann die Kupplungselemente 4, 5 eine Drehmitnahmestellung einnehmen. Bei dieser Axialverlagerung wird eine Kupplungsfeder 17 gespannt, die die beiden Kupplungselemente 4, 5 normalerweise in einer Abstandsstellung halten, in der die Kupplungsprofile nicht ineinander greifen, so dass in dieser Getrenntstellung der Drehknauf 3 gedreht werden kann, ohne dass das Schließglied 2 mitdreht.The
Bei den in den Zeichnungen dargestellten Ausführungsbeispielen besitzt der Drehknauf 3 eine axiale Höhlung, in die ein Wellenabschnitt 9, der einen Stößel ausbildet, eintaucht. Der Stößel 9 steckt in einer Höhlung eines Zylinderkernes 26, der innerhalb einer Kernbohrung des Zylindergehäuses 1 drehbar gelagert ist und welcher ein Kupplungselement 5 lagert. Das Kupplungselement 5 weist hierzu einen Zylinderabschnitt mit einer Sechskantöffnung 27 auf, der in einer zentralen Bohrung des Zylinderkernes 26 steckt. Der Stößel 9 besitzt an seinem in der Bohrung des Zylinderkernes 26 steckenden Ende einen Sechskantabschnitt 28, der in der Sechskantöffnung 27 steckt.In the embodiments shown in the drawings, the
Der Drehknauf 3 besitzt eine im Wesentlichen zylindrische Gestalt, wobei die Umfangskontur der Zylinderquerschnittsfläche im Wesentlichen eine Kreisbogenlinie ist. In der Zylinderumfangswandung befinden sich zwei Mulden 12. Diese Mulden 12 liegen sich diametral gegenüber. Die Mulden 12 besitzen einen Muldenrand 13 der zur Folge der gekrümmten Mantelfläche des Drehknaufes 3 ein niedrigstes Niveau in Bezug auf den Muldenboden aufweist. Der
In den Muldenböden der Mulden 12 befinden sich Lagerbohrungen 24. Die beiden Lagerbohrungen 24 fluchten miteinander und sind mit der Zentralbohrung zur Aufnahme des Wellenabschnittes 9 verbunden. In den jeweiligen Lagerbohrungen 24 stecken Druckknöpfe 6, 7. Die Druckknöpfe 6, 7 besitzen jeweils Betätigungsenden 6", 7", die von den nach außen weisenden Stirnflächen der Druckknöpfe 6, 7 gebildet sind. Im Ausführungsbeispiel sind die Stirnflächen 6", 7" Ebenen. Die Stirnflächen 6", 7" können aber auch gewölbt sein.In the trough bottoms of the
Die den Betätigungsenden 6", 7" gegenüberliegenden Enden der Druckknöpfe 6, 7 bilden Abtriebsenden 6', 7', die kegelförmig ausgebildet sind. Zwischen dem Abtriebsende 6', 7' und dem Betätigungsende 6", 7" besitzt jeder Druckknopf 6, 7 einen durchmesserverminderten Abschnitt 10. Dieser durchmesserverminderte Abschnitt 10 wird zur Fesselung des Druckknopfes 6, 7 in der Lagerbohrung 24 verwendet. Hierzu dient ein Fesselungsmittel 11.The actuating ends 6 ", 7" opposite ends of the
Das Fesselungsmittel 11 ist bei dem in den
Zwischen den beiden Abtriebsenden 6', 7' der Druckknöpfe 6, 7 ist in den Ausführungsbeispielen ein Bewegungsumlenkglied 18 angeordnet. Dieses Bewegungsumlenkglied 18 ist in der Lage, sich sowohl in Verlagerungsrichtung der beiden Druckknöpfe 6, 7 also quer zur Drehachse des Drehknaufes 3 zu verlagern, als auch sich in Richtung der Drehachse des Drehknaufes 3 zu verlagern. Eine Verlagerung in Richtung der Drehachse des Drehknaufes 3 hat eine Verlagerung des Wellenabschnittes 9 zur Folge. Dabei wird das Kupplungselement 5 in Richtung auf das Kupplungselement 4 verlagert und die Kupplungsfeder 17 gespannt. Diese Axialverlagerung des Wellenabschnittes 9 gegenüber dem Zylinderkern 26 ist möglich, weil die axiale Fesselung des Wellenabschnittes 9 an den Zylinderkern 26 über einen Stift 15 erfolgt, der ein Langloch 16 des Wellenabschnittes 9 durchgreift.Between the two output ends 6 ', 7' of the
Das Schließglied 2 ist an einen Wellenabschnitt 8 gekoppelt. Diese Kopplung kann auch beim Einstecken eines Schlüssels aufgehoben sein. Bei nichteingestecktem Schlüssel ist das Schließglied 2 jedenfalls drehfest mit dem Kupplungselement 4 verbunden, dessen zylinderförmiger Abschnitt in einer Zentralbohrung des Wellenabschnittes 8 steckt.The closing

Die Funktionsweise des erfindungsgemäßen Schließzylinders ist die Folgende:
- Ausgehend von einer in
den Figuren 4 ,10 ,14 dargestellten Normalstellung, in der die 6, 7 eine maximale radiale Entfernung von der Drehachse des Drehknaufes 3 besitzen und in der dieDruckknöpfe 4, 5 maximal weit voneinander entfernt liegen und in der das Schließglied nicht in einerKupplungselemente Drehmitnahmestellung zum Drehknauf 3 steht, können die 6, 7 radial bezogen auf die Drehknaufdrehachse verlagert werden, um diebeiden Druckknöpfe 4, 5 in eine Drehmitnahmestellung zu bringen, in der der Drehknauf 3beiden Kupplungselemente mit dem Schließglied 2 in einer Drehmitnahmestellung steht.
- Starting from one in the
FIGS. 4 .10 .14 illustrated normal position in which the 6, 7 have a maximum radial distance from the rotational axis of thepush buttons rotary knob 3 and in which the 4, 5 are far apart and in which the closing member is not in a rotational driving position to thecoupling elements knob 3, the both 6, 7 are radially displaced relative to the rotary knob rotational axis in order to bring the twopushbuttons 4, 5 in a rotational driving position, in which thecoupling elements rotary knob 3 is in a rotational driving position with the closingmember 2.
In der in den
Wird einer der beiden Druckknöpfe 6, 7 aus dieser Normalstellung verlagert, so hat dies eine Axialverlagerung des Bewegungsumlenkgliedes 18 und des Wellenabschnittes 9 zur Folge, so dass das Kupplungselement 5 unter Erhöhung der Federspannung der Kupplungsfeder 17 in Richtung auf das Kupplungselement 4 verlagert wird. Werden beide Druckknöpfe 6, 7 lediglich soweit verlagert, wie es die
In den
Bei einem nicht dargestellten Ausführungsbeispiel stecken die beiden Druckknöpfe 6, 7 nicht in Mulden 12. Während bei den in den Zeichnungen dargestellten Ausführungsbeispielen die Stirnflächen 6", 7" in keiner Verlagerungsstellung über das höchste Niveau des Muldenrandes 13 hinausragen, ist bei dem nichtdargestellten Ausführungsbeispiel vorgesehen, dass die Druckknöpfe 6, 7 in ihrer Normalstellung bis über die Zylindermantelfläche des Drehknaufes 3 hinausragen. Auch bei diesem Ausführungsbeispiel ist es erforderlich, dass zwei der beiden Druckknöpfe 6, 7 gleichzeitig betätigt werden müssen, um die Kupplungselemente 4, 5 in eine Eingriffsstellung zu bringen.In one embodiment, not shown, the two
Bei einem weiteren, nicht in den Zeichnungen dargestellten Ausführungsbeispiel ist lediglich ein Druckknopf 6 beziehungsweise 7 vorgesehen. Dieser Druckknopf 6 liegt allerdings in einer Mulde 12 und ist derart mit einem Bewegungsumlenkglied 18 getriebeverbunden, dass der Druckknopf 6 mit seinem Betätigungsende 6" bis unter das tiefste Niveau des Muldenrandes 13 verlagert werden muss, um die beiden Kupplungselemente 4, 5 in eine Drehmitnahmestellung zu bringen. Wird dieser einzige Druckknopf 6 lediglich soweit verlagert, dass sein Betätigungsende 6" auf dem Niveau des Muldenrandes 13 liegt, haben die Kupplungselemente 4, 5 eine Getrenntstellung.
