Description
Die vorliegende Erfindung bezieht sich auf einen Kupplungsmechanismus der im Oberbegriff des Anspruchs 1 genannten Art.The present invention relates to a coupling mechanism referred to in the preamble of
Das Dokument EP-A-0709535 offenbart einen Kupplungsmechanismus nach dem Oberbegriff des Anspruchs 1.Document EP-A-0709535 discloses a clutch mechanism according to the preamble of
Ein derartiger Kupplungsmechanismus ermöglicht eine selektive Kupplung der Drehbewegung zwischen einer ersten und einer zweiten Welle, so daß frei bestimmt werden kann, ob die eine der beiden Wellen, zum Beispiel die erste Welle, durch die Drehung der anderen Welle, zum Beispiel der zweiten Welle, mitgedreht wird, oder nicht.Such a coupling mechanism allows a selective coupling of the rotational movement between a first and a second shaft, so that it can be freely determined whether one of the two shafts, for example the first shaft, by the rotation of the other shaft, for example the second shaft, is turned on or not.
Dieser Mechanismus ist speziell für Schlösser entworfen, und zwar sowohl für mechanische als auch für elektromechanische Schlösser.This mechanism is specifically designed for locks, both mechanical and electromechanical locks.
Im folgenden wird davon ausgegangen, daß die erste Welle diejenige ist, die sich auf der Innenseite des Schlosses befindet; sie wird als "innenliegende Welle" bezeichnet. Die zweite Welle befindet sich auf der Außenseite des Schlosses und wird als "außenliegende Welle" bezeichnet.In the following, it is assumed that the first shaft is the one located on the inside of the lock; it is called an "internal wave". The second shaft is located on the outside of the lock and is referred to as "outboard shaft".
Ein charakteristisches Merkmal der Herstellung von Schlössern ist, daß ihnen hochindividualisierte Konstruktionen zugrundeliegen, selbst wenn es sich um ein und denselben Hersteller handelt. Das bedeutet, daß jedes Schloß eine ausschließlich hierfür verwendete Konstruktion aufweist und Teile benötigt, die nur hier Verwendung finden und nicht untereinander austauschbar sind, auch wenn ihre Funktion identisch ist. Dies bedeutet auch, daß man dann, wenn man die Leistungsmerkmale eines Schlosses verbessern möchte, üblicherweise eine Änderung an der jeweiligen ursprünglichen Konstruktion vornimmt, statt eine neue Konstruktion zu konzipieren; damit ist das Ergebnis erneut nur auf dieses konkrete Schloß anwendbar und nicht für andere.A characteristic feature of the manufacture of locks is that they are based on highly individualized designs, even if they are one and the same manufacturer. This means that each lock has a construction exclusively used for this purpose and requires parts that are only used here and are not interchangeable, even if their function is identical. This also means that if you want to improve the performance of a lock, you usually make a change to the respective original design, rather than a new one Design construction; Thus, the result is again applicable only to this specific lock and not for others.
Dies geschieht, wenn man neue Anforderungen erfüllen möchte, indem man die konventionelle mechanische Technologie anwendet, und auch, wenn man versucht, die moderne elektronische Technologie anzuwenden.This happens when you want to meet new requirements by using conventional mechanical technology and also when trying to apply modern electronic technology.
Das Ergebnis ist die Herstellung von Ausführungsformen, die hinsichtlich der Form und der Anzahl und Montage der Teile kompliziert sind und die nur als solche brauchbar sind. Um diese schwierige Situation richtig einzuschätzen, sei an die große Vielzahl von Arten von vorhandenen Schlössern gedacht (äußere und/oder innere Betätigung durch üblichen Schlüssel, durch Handgriff oder Klinke, durch üblichen Schlüssel und Handgriff oder Klinke durch elektromechanische Mechanismen mit Handgriff, Klinke oder Schließzylinder, etc.).The result is the production of embodiments that are complicated in terms of the shape and number and assembly of the parts and that are useful only as such. To properly assess this difficult situation, consider the large variety of types of existing locks (external and / or internal operation by usual key, handle or latch, by usual key and handle or latch by electromechanical mechanisms with handle, latch or lock cylinder , Etc.).
Der Erfindung liegt die Aufgabe zugrunde, einen Kupplungsmechanismus der eingangs genannten Art zu schaffen, der bei kompakter und einfacher Konstruktion eine selektive Kupplung zwischen zwei Wellen in deren Drehrichtung ermöglicht, unabhängig davon, ob diese Wellen zu einem mechanischen oder einem elektromechanischem Schloß gehören, sowie unabhängig davon, ob auf diesen Wellen innere und/oder äußere Handgriffe oder Klinken befestigt sind.The invention has for its object to provide a coupling mechanism of the type mentioned, which allows a compact and simple construction, a selective coupling between two waves in the direction of rotation, regardless of whether these waves belong to a mechanical or an electromechanical lock, and independently of whether internal and / or external handles or pawls are attached to these shafts.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
Der erfindungsgemäße Kupplungsmechanismus umfaßt eine innenliegende Welle, eine außenliegende Welle, einen Statorkörper, einen Satz von radialen Zuhaltungsstiften und radialen Gegen-Zuhaltungsstiften und eine radiale Betätigungsvorrichtung, wobei die innenliegende Welle, die außenliegende Welle und der Statorkörper eine koaxial zueinander angeordnet sind und die außenliegende Welle frei drehbar in das Innere der innenliegenden Welle vorspringt, während beide Wellen (innenliegende und außenliegende Welle) frei drehbar in dem Statorkörper befestigt sind. Der genannte Satz von radialen Zuhaltungsstiften und radialen Gegen-Zuhaltungsstiften ist gleitend verschiebbar zwischen der Betätigungvorrichtung, die mit dem radialen Zuhaltungsstift in Kontakt steht, und einer radialen Druckfeder eingebaut, die zwischen dem radialen Gegen-Zuhaltungsstift und dem Boden eines Sitzes der außenliegenden Welle wirkt. Der radiale Zuhaltungsstift und der radiale Gegen-Zuhaltungsstift sind in Kombination miteinander so bemessen, daß ausschließlich der eine oder der andere die Grenzfläche zwischen dem Umfang des Außendurchmessers der außenliegenden Welle und den Umfang des Innendurchmessers der innenliegenden Welle durchquert. Die radiale Betätigungsvorrichtung ist durch eine bogenförmige Platte und zumindest eine Stange gebildet, wobei die bogenförmige Platte in einem ringförmigen Hohlraum zwischen der innenliegenden Welle und dem Statorkörper angeordnet ist, wobei sich diese bogenförmige Platte in Umfangsrichtung über einen Bogen erstreckt, der den Winkelsektor des Betriebsdrehungsbereichs der innenliegenden Welle auf der einen und der anderen Seite einer in der Mitte liegenden Ruhestellung überdeckt. Die Stange der radialen Betätigungsvorrichtung ist mit Gleitsitz in dem Statorkörper befestigt, und wenn es sich um eine einzelne Stange handelt, befindet sich die Stange am Mittelpunkt der bogenförmigen Platte und ist mit den radialen Zuhaltungs- und Gegen-Zuhaltungsstiften in der Ruhestellung ausgerichtet.The clutch mechanism of the invention comprises an inner shaft, an outer shaft, a stator body, a set of radial tumbler pins and radial anti-tumbler pins, and a radial actuator, wherein the inner shaft, the outer shaft and the stator body are arranged coaxially with each other and the outer shaft freely rotatably protrudes into the interior of the inner shaft, while both shafts (inner and outer shafts) are freely rotatably mounted in the stator body. Said set of radial tumbler pins and radial counter-tumbler pins are slidably mounted between the actuator in contact with the radial tumbler pin and a radial compression spring which acts between the radial tumbler pin and the bottom of a seat of the outboard shaft. The radial tumbler pin and the radial anti-tumble pin are dimensioned in combination with each other so that only one or the other crosses the interface between the circumference of the outer diameter of the outer shaft and the circumference of the inner diameter of the inner shaft. The radial actuator is formed by an arcuate plate and at least one rod, the arcuate plate being disposed in an annular cavity between the inner shaft and the stator body, said arcuate plate extending circumferentially over an arc defining the angular sector of the operational rotation range of the inside wave on one side and the other side of a lying in the middle rest position covered. The rod of the radial actuator is slidably mounted in the stator body, and if it is a single rod, the rod is at the center of the arcuate plate and is aligned with the radial tumbler and counter-tumbler pins in the rest position.
Die erfindungsgemäße Konstruktion weist eine einfache Funktionweise auf, die darin besteht, daß wenn die radiale Betätigungsvorrichtung nicht betätigt ist, der Kontakt zwischen dem Zuhaltungsstift und dem Gegen-Zuhaltungsstift genau auf der Grenzfläche der Drehkupplung zwischen der innenliegenden und der außenliegenden Welle erfolgt, während gleichzeitig der Zuhaltungsstift von dem Mittelpunkt der konkaven Fläche der bogenförmigen Platte der radialen Betätigungsvorrichtung abgestützt ist; dies bedeutet, daß beide Achsen sich unabhängig voneinander drehen können, so daß, wenn nur die innenliegende Welle mit dem eigentlichen Schloßmechanismus verbunden ist, die Tür von innen her und nicht von außen her geöffnet werden kann.The construction of the invention has a simple operation, which consists in that when the radial actuator is not actuated, the contact between the tumbler pin and the counter-tumbler pin exactly on the interface of the rotary coupling between the inner and the outer shaft, while the same Tumbler pin is supported by the center of the concave surface of the arcuate plate of the radial actuator; this means that both axes are can rotate independently of each other, so that if only the internal shaft is connected to the actual lock mechanism, the door can be opened from the inside and not from the outside.
Wenn andererseits die radiale Betätigungsvorrichtung betätigt ist (eingekuppelter Zustand), so kann der Zuhaltungsstift oder der Gegen-Zuhaltungsstift die Grenzfläche der Drehkupplung zwischen der innenliegenden Welle und der außenliegenden Welle durchqueren, was durch ein elastisches Zurückziehen oder Ausfahren des Gegen-Zuhaltungsstifts gegen seine Druckfeder im Inneren seines Sitzes erfolgt. Dies bedeutet, daß die Tür sowohl von innen her als auch von außen her geöffnet werden kann, nachdem die radiale Betätigungsvorrichtung verschoben wurde, was mit Hilfe von mechanischen oder elektromechanischen Einrichtungen erfolgt.On the other hand, when the radial actuator is actuated (engaged state), the tumbler pin or the anti-tumble pin can traverse the interface of the rotary joint between the inner shaft and the outer shaft, by resiliently retracting or extending the anti-tumble pin against its compression spring in the Inside of his seat done. This means that the door can be opened from the inside as well as from the outside after the radial actuating device has been displaced, which takes place with the aid of mechanical or electromechanical devices.
In jedem der beschriebenen Zustände und während des gesamten Betriebshubes der innenliegenden Welle in der einen oder anderen Richtung läuft der Zuhaltungsstift dauernd abgestützt auf der bogenförmigen Platte der radialen Betätigungsvorrichtung, was eine sanfte und zuverlässige Betriebsweise ergibt.In each of the states described and during the entire operating stroke of the internal shaft in one or the other direction, the tumbler pin constantly rests on the arcuate plate of the radial actuator, resulting in a smooth and reliable operation.
Gemäß einem weiteren Merkmal der Erfindung ist ein gleitendes Betätigungselement vorgesehen, das durch den Statorkörper hindurch eingebaut ist. Bezüglich der Ruhe-Drehstellung der innenliegenden Welle ist dieses gleitende Betätigungselement zwischen einer Spitze, die auf der Außenseite des Statorkörpers in Kontakt mit dem Betätigungshebel eines elektrischen Mikroschalters in einer Betriebsstellung dieses Mikroschalters in Berührung steht, und einem abgerundeten Kopf angeordnet, der gegen den Boden einer Aussparung anliegt, der in der innenliegenden Welle mit rampenförmigen Seitenflächen ausgebildet ist, die divergierend in eine kreisringförmige Umfangsbahn der eigentlichen innenliegenden Welle übergehen, wobei die Aussparung eine Tiefe aufweist, die dem Betriebshub des Betätigungshebels des Mikroschalters entspricht, wobei der abgerundete Kopf des gleitenden Betätigungselements mit seiner Rückseite gegen ein Ende einer Schrauben-Druckfeder anliegt, die an ihrem anderen Ende gegen den Statorkörper anliegt.According to a further feature of the invention, a sliding actuating element is provided which is installed through the stator body. With respect to the idle rotational position of the inner shaft, this sliding actuator is disposed between a tip which is in contact with the operating lever of an electric microswitch in contact with the operating lever of an electric microswitch in an operating position of this microswitch, and a rounded head which is against the bottom of a Recess rests, which is formed in the inner shaft with ramp-shaped side surfaces which diverging into an annular circumferential path of the actual internal shaft, wherein the recess has a depth corresponding to the operating stroke of the actuating lever of the microswitch, wherein the rounded head of the sliding actuating element with its Rear abuts against one end of a compression coil spring, which bears against the stator at its other end.
Diese Konstruktion bewirkt, daß eine Drehung der innenliegenden Welle ausgehend von ihrer Ruhestellung dazu führt, daß das gleitende Betätigungselement nach außen aus dem Statorkörper heraus angetrieben wird, und die Betätigung des Mikroschalters bewirkt, wodurch sich ein elektrisches Signal ergibt, das die Position dieses gleitenden Betätigungselements anzeigt, und das in Funktion hiervon für zusätzliche Funktionen des Schließsystems oder der eigentlichen Kupplung verwendet werden kann. Außerdem dient der Sitz des Kopfes des gleitenden Betätigungselements in der Aussparung der innenliegenden Achse zur Markierung einer Position, die die Montage erleichtert und die das genaue Erreichen der Ruhestellung begünstigt, in der genau der Übergang zwischen den ausgekuppelten und eingekuppelten Zuständen des erfindungsgemäßen Mechanismus erfolgen kann.This construction causes a rotation of the inner shaft from its rest position causes the sliding actuator is driven outwardly out of the stator, and the actuation of the micro-switch causes, resulting in an electrical signal representing the position of this sliding actuator and, in function thereof, may be used for additional functions of the locking system or the actual clutch. In addition, the seat of the head of the sliding actuator in the recess of the inner axis serves to mark a position that facilitates assembly and favors the exact achievement of the rest position, in which the transition between the disengaged and coupled states of the mechanism according to the invention can take place.
Eine weitere Besonderheit der Erfindung besteht darin, daß der Statorkörper ein Paar von Seitenplatten beinhaltet, die parallel zur Betriebsbewegung der bogenförmigen Platte der radialen Betätigungsvorrichtung angeordnet sind, und die über die Amplitude dieser Betriebsbewegung hinaus vorspringen, wobei diese Seitenplatten jeweils gegen ein Ende der bogenförmigen Platte anliegen. Diese Anordnung verbessert die Führung der radialen Betätigungsvorrichtung und bildet ein zusätzliches Widerstandselement an den Enden der bogenförmigen Platte, wenn der Zuhaltungsstift an diesen Enden abgestützt wird.Another peculiarity of the invention is that the stator body includes a pair of side plates arranged parallel to the operating movement of the arcuate plate of the radial actuator and projecting beyond the amplitude of this operating movement, these side plates respectively against an end of the arcuate plate issue. This arrangement improves the guidance of the radial actuator and forms an additional resistance element at the ends of the arcuate plate when the tumbler pin is supported at these ends.

Wie dies in Figur 1 gezeigt ist, umfaßt dieser Mechanismus eine (bezogen auf das Schloß oder eine Tür auf der Innenseite angeordnete) innenliegende Welle (1), eine (bezogen auf das Schloß oder eine Tür auf der Außenseite angeordnete) außenliegende Welle (2), einen Statorkörper (3), einen Satz aus einem radialen Zuhaltungsstift (4) und einem radialen Gegen-Zuhaltungsstift (5) und eine in Radialrichtung bewegliche Betätigungsvorrichtung (6). Die innenliegende Welle (1), die außenliegende Welle (2) und der Statorkörper (3) bilden eine koaxiale Konstruktion , bei der die außenliegende Welle (2) frei drehbar in das Innere eines hohlzylindrischen Abschnittes der innenliegenden Welle (1) vorspringt, wobei sowohl die innenliegende Welle (1) als auch die außenliegende Welle (2) frei drehbar in dem Statorkörper (3) angeordnet sind. Der Satz aus dem radialen Zuhaltungsstift (4) und dem radialen Gegen-Zuhaltungsstift (5) ist gleitend verschiebbar zwischen der Betätigungsvorrichtung (6), die mit dem radialen Zuhaltungsstift (4) in Kontakt steht, und einer radialen Druckfeder (7) eingebaut, die zwischen dem radialen Gegen-Zuhaltungsstift (5) und dem Boden eines Sitzes (2a) in der außenliegenden Welle (2) liegt, wobei der radiale Zuhaltungsstift (4) und der radiale Gegen-Zuhaltungsstift (5) in Kombination untereinander so bemessen sind, daß in einander ausschließender Weise der eine oder der andere die Grenzfläche zwischen dem Umfang des Außendurchmessers der außenliegenden Welle (2) und dem Umfang des Innendurchmessers der innenliegenden Welle (1) durchqueren kann, um die beiden Wellen in Abhängigkeit von der Position der Betätigungsvorrichtung miteinander zu kuppeln.As shown in Figure 1, this mechanism comprises an inner shaft (1) (with respect to the lock or a door on the inner side), an outer shaft (2) (with respect to the lock or a door on the outer side). a stator body (3), a set of a radial tumbler pin (4) and a radial anti-tumble pin (5), and a radially movable actuator (6). The inner shaft (1), the outer shaft (2) and the stator body (3) form a coaxial construction in which the outer shaft (2) freely rotates into the interior of a hollow cylindrical portion of the inner shaft (1) the inner shaft (1) and the outer shaft (2) are freely rotatably arranged in the stator body (3). The set of the radial tumbler pin (4) and the radial counter-tumbler pin (5) is slidably installed between the actuator (6) in contact with the radial tumbler pin (4) and a radial compression spring (7) between the radial counter-tumbler pin (5) and the bottom of a seat (2a) in the outer shaft (2), wherein the radial tumbler pin (4) and the radial anti-tumble pin (5) are dimensioned in combination with one another such that in mutually exclusive manner, one or the other may traverse the interface between the circumference of the outer diameter of the outer shaft (2) and the circumference of the inner diameter of the inner shaft (1) to couple the two shafts together in response to the position of the actuator ,
Die radiale Betätigungsvorrichtung (6) ist durch eine bogenförmige Platte (6a) und durch zumindest einer Stange (6b) gebildet ist, wobei die bogenförmige Platte (6a) in einem ringförmigen Hohlraum (8) angeordnet ist, der zwischen der innenliegenden Welle (1) und dem Statorkörper (3) gebildet ist. Die bogenförmige Platte (6a) erstreckt sich bogenförmig in Umfangsrichtung über einen Winkelsektor, der dem (beispielsweise für das Entriegeln eines Schlosses erforderlichen) Betriebs-Drehhub der innenliegenden Welle (1) zur einen oder anderen Seite einer in der Mitte liegenden Ruhestellung entspricht. Die Stange (6b) der radialen Betätigungsvorrichtung (6) ist gleitend in den Statorkörper (1) eingebaut, und wenn nur eine Stange vorgesehen ist, so ist diese Stange (6b) am Mittelpunkt der bogenförmigen Platte (6a) angeordnet und mit dem radialen Zuhaltungsstift (4) und dem radialen Gegen-Zuhaltungsstift (5) in der genannten Ruhestellung ausgerichtet.The radial actuating device (6) is formed by an arcuate plate (6a) and by at least one rod (6b), the arcuate plate (6a) being arranged in an annular cavity (8) arranged between the inner shaft (1). and the stator body (3) is formed. The arcuate plate (6a) extends arcuately in the circumferential direction over an angle sector, which corresponds to the (for example, for unlocking a lock required) operating rotary stroke of the inner shaft (1) to one or the other side of a lying in the middle rest position. The rod (6b) of the radial actuator (6) is slidably installed in the stator body (1), and if only one rod is provided, this rod (6b) is located at the center of the arcuate plate (6a) and with the radial tumbler pin (4) and the radial counter-tumbler pin (5) aligned in said rest position.
Diese Figur 1 bezieht sich auf eine bevorzugte Ausführungsform, bei der von dem Satz aus dem radialen Zuhaltungsstift (4) und dem radialen Gegen-Zuhaltungsstift (5) der radiale Zuhaltungsstift (4) gleitend in einer mit dem Sitz (2a) ausrichtbaren Bohrung des hohlzylindrischen Abschnittes der innenliegenden Welle (1) angeordnet ist und eine Länge aufweist, die gleich der Wandstärke dieser innenliegenden Welle (1) an der Stelle der Bohrung ist. Der radiale Gegen-Zuhaltungsstift (5) ist gleitend in dem Sitz 2a der außenliegenden Welle (2) angeordnet. Der Gegen-Zuhaltungsstift (5) weist eine derartige Länge auf, daß bei maximaler betriebsmäßiger Entspannung der Druckfeder (7) in der in der Mitte liegenden Ruhestellung der innenliegenden Welle (1) die Spitze des Gegen-Zuhaltungsstiftes (5) über den Außendurchmesser der außenliegenden Welle (2) in einem Ausmaß vorspringen kann, die angenähert gleich der halben Wandstärke der innenliegenden Welle (1) und gleich dem radialen Betriebshub der bogenförmigen Platte (6a) in dem ringförmigen Hohlraum (8) ist.This figure 1 relates to a preferred embodiment in which of the set of the radial tumbler pin (4) and the radial counter-tumbler pin (5) of the radial tumbler pin (4) slidably in a with the seat (2a) alignable bore of the hollow cylindrical Section of the inner shaft (1) is arranged and has a length which is equal to the wall thickness of this inner shaft (1) at the location of the bore. The radial counter-tumbler pin (5) is slidably disposed in the
Die Figuren 2 bis 5 zeigen die gemeinsame Montage der Elemente der Ausführungsform nach Figur 1 in verschiedenen Zuständen und Betriebsstellungen. Die Figur 2 zeigt die Ausgangs-Ruhestellung, in der der Mechanismus sich im entkuppelten Zustand befindet und die innenliegende Welle (1) und die außenliegende Welle (2) unabhängig voneinander drehbar sind, wie dies in Figur 3 gezeigt ist, in der die außenliegende Welle (2) gedreht wurde, ohne die innenliegende Welle (1) mitzunehmen. Hierbei stützt die Platte (6a) den Zuhaltungsstift (4) so ab, daß er im Inneren der Wandstärke der Innenliegenden Welle (1) liegt und die Kontaktfläche zwischen den Zuhaltungsstiften (4, 5) mit der Grenzfläche zwischen dem Außenumfang der außenliegenden Welle (2) und dem Innenumfang der innenliegenden Welle (1) ausgerichtet ist.Figures 2 to 5 show the common assembly of the elements of the embodiment of Figure 1 in different states and operating positions. Figure 2 shows the initial rest position in which the mechanism is in the decoupled state and the inner shaft (1) and the outer shaft (2) are independently rotatable, as shown in Figure 3, in which the outer shaft (2) was rotated without taking the inner shaft (1). Here, the plate (6a) supports the tumbler pin (4) so that it is inside the wall thickness of the inner Shaft (1) and the contact surface between the tumbler pins (4, 5) with the interface between the outer periphery of the outer shaft (2) and the inner circumference of the inner shaft (1) is aligned.
Wenn die radiale Betätigungsvorrichtung (6) durch mechanische oder elektromechanische Mittel radial nach außen verschoben ist, erstreckt sich der radiale Gegen-Zuhaltungsstift (5) (gemäß Figur 4) durch die Grenzfläche zwischen der innenliegenden Welle (1) und der außenliegenden Welle (2) derart, daß die Drehung der letzteren die erstere mitnimmt, wie dies in Figur 5 zu sehen ist.When the radial actuating device (6) is displaced radially outwards by mechanical or electromechanical means, the radial anti-tumble pin (5) (according to FIG. 4) extends through the interface between the inner shaft (1) and the outer shaft (2). such that the rotation of the latter entrains the former, as can be seen in FIG.
Ein weiteres Merkmal der Erfindung besteht in dem Vorhandensein eines gleitend verschiebbaren Betätigungselementes (9), das durch den Statorkörper (3) hindurch eingebaut ist, wobei bezüglich der Ruhe-Drehstellung der innenliegenden Welle (1) dieses gleitende Betätigungselement (9) zwischen einer Spitze (9a), die außerhalb des Statorkörpers (3) in Kontakt mit dem Betätigungshebel (10a) eines Mikroschalters (10) in einer Betriebsstellung dieses Schalters steht, und einen abgerundeten Kopf (9b) angeordnet ist, der gegen den Boden einer Aussparung (1a) anliegt, die in der innenliegenden Welle (1) ausgebildet ist und seitliche Wänden auweist, die rampenförmig divergieren, um in eine kreisringförmige Umfangsbahn (1b) am Außenumfang der innenliegenden Welle (1) überzugehen. Diese Aussparung (1a) weist eine Tiefe auf, die dem Betriebshub des Betätigungshebels (10a) des Mikroschalters (10) entspricht, und der abgerundete Kopf (9b) des gleitenden Betätigungselementes (9) liegt mit seinem Rücken gegen das Ende einer Schraubendruckfeder (11) an, die mit ihrem anderen Ende gegen den Statorkörper (3) anliegt.A further feature of the invention consists in the presence of a slidable actuating element (9) which is installed through the stator body (3), wherein with respect to the rest rotational position of the internal shaft (1) of this sliding actuating element (9) between a tip ( 9a) which is outside the stator body (3) in contact with the operating lever (10a) of a microswitch (10) in an operative position of this switch, and a rounded head (9b) is arranged, which bears against the bottom of a recess (1a) formed in the inner shaft (1) and having lateral walls which diverge rampwise to transition into an annular peripheral path (1b) on the outer circumference of the inner shaft (1). This recess (1a) has a depth which corresponds to the operating stroke of the actuating lever (10a) of the microswitch (10), and the rounded head (9b) of the sliding actuating element (9) lies with its back against the end of a helical compression spring (11). on, which rests with its other end against the stator body (3).
Die Funktionsweise dieser Vorrichtung ist klar anhand eines Vergleichs der Figuren 4 und 5 ersichtlich, in denen für die spezielle kombinierte Konfiguration der Aussparung (1b) und des abgerundeten Kopfes (9b) beim Drehen der innenliegenden Welle (1) eine Ausfahrbewegung des gleitenden Betätigungselementes (9) gegen die Schraubenfeder (11) hervorgerufen wird, was dazu führt, daß die Spitze (9a) den Betätigungshebel (10a) des Mikroschalters (10) betätigt.The operation of this device is clearly apparent from a comparison of Figures 4 and 5, in which for the special combined configuration of the recess (1b) and the rounded head (9b) during rotation of the inner shaft (1) an extension movement of the sliding actuating element (9 ) is caused against the coil spring (11), what causes the tip (9a) actuates the operating lever (10a) of the microswitch (10).
Eine weitere Besonderheit der Erfindung besteht darin, daß der Statorkörper ein Paar von Seitenplatten (12) aufweist, die sich parallel zur Betriebsbewegung der bogenförmigen Platte (6a) erstrecken und die sich über die Bewegungsstrecke dieser Bewegung hinaus erstrecken, wobei sie jeweils gegen ein Ende der bogenförmigen Platte (6a) anliegen. Diese Option ist in den Figuren 6 bis 8 gezeigt. Insbesondere zeigt eine Betrachtung der Figuren 7 und 8 die zusammenwirkende Funktion der Seitenplatten (12) bei der Führung der Enden der bogenförmigen Platte (6a) und sie ergeben an diesen Enden außerdem eine zusätzliche Festigkeit, wenn der Zuhaltungsstift eine Position erreicht, in der er über diesen Enden liegt, ähnlich wie in Figur 5.Another particularity of the invention is that the stator body has a pair of side plates (12) extending parallel to the operative movement of the arcuate plate (6a) and extending beyond the path of travel of that movement, each against one end of the movement abut arcuate plate (6a). This option is shown in Figs. 6-8. In particular, a consideration of Figures 7 and 8 shows the cooperating function of the side plates (12) in guiding the ends of the arcuate plate (6a) and also provide additional strength at these ends when the tumbler pin reaches a position in which it passes over these ends, similar to Figure 5.
Eine weitere Ausführungsform ist in den Figuren 6 bis 8 gezeigt, Bei dieser Ausführungsform weist bei dem Satz aus dem radialen Zuhaltungsstift (4) und dem radialen Gegen-Zuhaltungsstift (5) der gleitend in der außenliegenden Welle (2) angeordnete Gegen-Zuhaltungsstift (5) und eine derartige Länge auf, daß wenn sich die Druckfeder (7) in ihrem Zustand maximaler Betriebsentspannung befindet und die innenliegende Welle (1) ihre in der Mitte liegende Ruhestellung einnimmt, dieser radiale Gegenzuhaltungsstift (5) mit seiner Spitze am Außendurchmesser der außenliegenden Welle (2) und damit an der genannten Grenzfläche liegt, wobei gleichzeitig der radiale Zuhaltungsstift (4) gleitend in der innenliegenden Welle (1) angeordnet ist und eine Länge aufweist, die die Wandstärke dieser innenliegenden Welle (1) in einem Ausmaß übersteigt, die gleich dem radialen Betriebshub der bogenförmigen Platte (6a) in dem kreisringförmigen Hohlraum (8) ist. In diesem Fall sind der Längen des radialen Zuhaltungsstiftes (4) und des radialen Gegen-Zuhaltungsstiftes (5) derart, daß, wie dies in Figur 8 gezeigt ist, die Drehkupplung der innenliegenden Achse (1) und der außenliegenden Achse (2) (eingekuppelter Zustand) durch den radialen Zuhaltungsstift (4) bewirkt wird, der die Grenzfläche durchquert. Es sei darauf hingewiesen, daß hier der eingekuppelte Zustand dann erreicht wird, wenn die bogenförmige Platte (6a) gegen den Außenumfang der innenliegenden Welle anliegt, während bei der vorhergehenden Ausführungsform dieser Zustand erreicht wird, wenn diese bogenförmige Platte (6a) gegen den Statorkörper (3) anliegt (Figur 5).A further embodiment is shown in FIGS. 6 to 8. In this embodiment, in the set of the radial tumbler pin (4) and the radial counter-tumbler pin (5), the counter-tumbler pin (5) slidably disposed in the outboard shaft (2) ) and a length such that when the compression spring (7) is in its maximum operating relaxation state and the inner shaft (1) assumes its central resting position, this radial counter-retaining pin (5) has its tip on the outer diameter of the outer shaft (2) and thus located at said interface, wherein at the same time the radial tumbler pin (4) is slidably disposed in the inner shaft (1) and has a length which exceeds the wall thickness of this inner shaft (1) to an extent equal to the radial operating stroke of the arcuate plate (6a) in the annular cavity (8). In this case, the lengths of the radial tumbler pin (4) and the radial anti-tumble pin (5) are such that, as shown in Figure 8, the rotary joint of the inner axle (1) and the outer axle (2) (coupled State) is caused by the radial tumbler pin (4) passing through the interface. It should be noted that here the engaged state then is achieved when the arcuate plate (6a) abuts against the outer periphery of the inner shaft, while in the previous embodiment, this state is achieved when this arcuate plate (6a) abuts against the stator (3) (Figure 5).
Eine weitere alternative Ausführungsform ist in den Figuren 9 bis 11 dargestellt, wobei diese Ausführungsform im wesentlichen identisch zu der vorhergehenden ist (Figuren 6 bis 8), mit der einzigen Ausnahme, daß die Seitenplatten (12) fortgelassen sind. Es ist zu erkennen, daß diese Fortlassung der Seitenplatten in gleicher Weise bei der ersten Ausführungsform möglich ist, die in den Figuren 1 bis 5 gezeigt ist.A further alternative embodiment is shown in Figures 9 to 11, this embodiment being substantially identical to the previous one (Figures 6 to 8), with the sole exception that the side plates (12) are omitted. It will be understood that this omission of the side plates is equally possible in the first embodiment shown in Figs. 1-5.
