Description
Die vorliegende Erfindung betrifft eine Halte- und Indexierungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1. Dieser bezieht sich insbesondere auf eine Halte- und Indexierungsvorrichtung zur Integration in eine Stellvorrichtung von Uhren, insbesondere von Armbanduhren, wobei die Vorrichtung eine fest angebrachte Buchse, eine innerhalb der Buchse sowohl axial verschiebbar als auch drehbar gelagerte Achse, ein am ins Uhrinnere gerichteten Ende der Achse angebrachtes Übermittlungsorgan, welches den Antrieb eines im Uhrinneren befindlichen Uhrteils erlaubt, sowie zumindest ein elastisches Element, welches eine in axialer Richtung der Achse wirkende Vorspannkraft ausübt, aufweist. Die Erfindung bezieht sich auch auf eine Stellvorrichtung, welche eine derartige Halte- und Indexierungsvorrichtung besitzt, sowie eine Uhr mit einer solchen Stellvorrichtung.The present invention relates to a holding and indexing device according to the preamble of
Stelleinheiten, insbesondere in Form von drehbar und/oder ziehbar angebrachten Kronen, erlauben die Einstellung diverser beweglicher Bauteile, welche sich innerhalb der zugehörigen Uhr befinden, etwa einer Datumsanzeige, einer Weltzeitscheibe, einer Mondscheibe, eines insbesondere bei Taucheruhren verbreiteten Innendrehrings, der dort zur Anzeige der verbleibenden Tauchzeit benutzt wird, oder dergleichen. Die Einstellung wird hierbei normalerweise manuell vom Benutzer der Uhr vorgenommen, nachdem dieser die Stelleinheit in eine entsprechende Position gebracht hat, welche die Einstellung erlaubt, während ansonsten die Einstellmöglichkeit durch Auskupplung deaktiviert ist. Bei Taucheruhren oder anderen Anwendungen, bei denen sicherheitsrelevante Aspekte eine Rolle spielen, sind auch selbsttätig umschaltende Stelleinheiten, die die Aus- und Einkupplung automatisch vornehmen, bekannt, etwa aus dem Dokument
Das bewegliche Bauteil, im Falle des Dokuments

Bei den vorbekannten Stelleinheiten wird daher das Halten des beweglichen Bauteils in der einmal eingestellten Position sowie, falls vorhanden, die Indexierung des Einstellvorgangs über eine mit Kerben zusammenarbeitende Rastfedern bzw. Stifte, über Reibungseffekte, oder über eine teilweise fest am Uhrgehäuse verbaute Kupplung verwirklicht.In the prior art actuators, therefore, the holding of the movable member in the once set position and, if present, the indexing of the adjustment via a notch cooperating detent springs or pins, on friction effects, or realized via a partially fixedly mounted on the watch case coupling.
Dies ist aus verschiedenen Gründen nicht immer erwünscht oder zieht gar Nachteile nach sich. Zum Beispiel kann die Federkraft der Rastfeder oder die Reibungskraft nicht immer mit der nötigen Genauigkeit, etwa auf Grund von fertigungstechnischen Schwankungen oder der konstruktiven Auslegung der Rastfeder, eingestellt werden. Insbesondere läßt sich die Federkraft von Blattfedern weniger genau als die von Spiralfedern einstellen. Eine Rastfeder bedingt des weiteren einen eigenen, zusätzlichen Eingriffspunkt an der Peripherie des beweglichen, einstellbaren Bauteils, was einen erhöhten Raumbedarf sowie, je nach Art des beweglichen Bauteils und der sonst noch mit diesem im Zusammenspiel befindlichen Teile, eine erhöhte Komplexität oder Einschränkungen bei der Auslegung der zugehörigen Uhr nach sich ziehen kann. Auch müssen am beweglichen Bauteil entsprechende Kerben vorgesehen werden, was unerwünscht sein kann. Zudem läßt sich durch Reibungskraft alleine nur eine sehr grobe Sicherung des Bauteils in der eingestellten Position erreichen, jedoch keine Indexierung des Einstellvorgangs.This is not always desirable for various reasons or even disadvantages. For example, the spring force of the detent spring or the friction force can not always be adjusted with the necessary accuracy, such as due to manufacturing fluctuations or the structural design of the detent spring. In particular, the spring force of leaf springs can be less accurate than set of coil springs. A detent spring also requires its own additional point of engagement at the periphery of the movable, adjustable component, which increases the space required and, depending on the nature of the moving component and the otherwise interacting with this parts, an increased complexity or design restrictions the associated clock. Also, corresponding notches must be provided on the movable component, which may be undesirable. In addition, only a very rough securing of the component in the set position can be achieved by friction force alone, but no indexing of the adjustment process.
Das Ziel der vorliegenden Erfindung ist daher die Vermeidung der vorgenannten Nachteile und die Bereitstellung einer Halte- und Indexierungsvorrichtung, welche das Halten des beweglichen Bauteils in der einmal eingestellten Position sowie die Indexierung des Einstellvorgangs auf sichere, konstruktiv elegante, flexible, und platzsparende Weise verwirklicht.The aim of the present invention is therefore to avoid the aforementioned drawbacks and to provide a holding and indexing device, which comprises holding the movable member in the Once set and indexing the setting process in a safe, structurally elegant, flexible, and space-saving manner realized.
Der Gegenstand der vorliegenden Erfindung zeichnet sich hierfür durch die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale aus.The object of the present invention is characterized by the features mentioned in the characterizing part of
Insbesondere weist eine erfindungsgemäße Halte- und Indexierungsvorrichtung einen an besagter Achse axial gleitend angebrachten Indexierungsring mit einer Indexierungszahnung sowie das besagte Übermittlungsorgan an seiner in Richtung des Indexierungsrings weisenden Seitenfläche eine durch die Wirkung der Vorspannkraft des elastischen Elements mit der besagten Indexierungszahnung in Eingriff stehende Seitenzahnung auf, wobei in zumindest einer Drehrichtung der Achse eine Krafteinwirkung einer vordefinierten Größe auf den Indexierungsring ein Auskuppeln zwischen der Indexierungsverzahnung und der Seitenzahnung bewirkt und dadurch eine Positionsindexierung des besagten Uhrteils erlaubt.In particular, a holding and indexing device according to the invention has an indexing ring with indexing teeth axially slidably mounted on said axis, and said transmitting means has, on its side facing the indexing ring, a side toothing in engagement with said indexing teeth by the action of the biasing force of the resilient member. wherein in at least one direction of rotation of the axle, a force of a predefined amount on the indexing ring causes disengagement between the indexing and side teeth, thereby permitting positional indexing of said portion of the watch.
Durch diese Merkmale werden eine Reihe von Vorteilen erzielt. So kann eine Halte- und Indexierungsvorrichtung gemäß der vorliegenden Erfindung direkt in die zugehörige Stellvorrichtung integriert werden, wodurch kein zusätzlicher Raumbedarf an der Peripherie des beweglichen Bauteils entsteht. Die Halte- und Indexierungsvorrichtung kann gar einige ohnehin in manchen Stellvorrichtungen vorhandene Teile nutzen und stellt daher eine konstruktiv sehr interessante Lösung dar. Zudem kann durch die vorgeschlagene Lösung sowohl die Sicherung des beweglichen Bauteils in der eingestellten Position als auch die Indexierung des Einstellvorgangs verwirklicht werden. Die Vorrichtung ist robust und zeichnet sich durch einen sicheren Funktionsablauf aus. Sie kann in eine Vielzahl von Stellvorrichtungen und damit in diverse Uhren integriert werden, ohne dort nennenswerte Änderungen zu bedingen. Diese Eigenschaften sind laut der vorliegenden Erfindung auf relativ einfache Art und Weise realisiert.These features provide a number of advantages. Thus, a holding and indexing device according to the present invention can be integrated directly into the associated adjusting device, whereby no additional space is required at the periphery of the movable member. The holding and indexing device can even use some existing anyway in some actuators parts and therefore represents a structurally very interesting solution. In addition, the proposed solution, both the securing of the movable member in the set position and the indexing of the setting process can be realized. The device is robust and characterized by a safe functional sequence. It can be integrated in a variety of adjusting devices and thus in various watches, without causing any significant changes there. These properties are realized according to the present invention in a relatively simple manner.

Die Erfindung wird nun im folgenden unter Verweis auf die Abbildungen im Detail beschrieben werden.The invention will now be described in detail below with reference to the drawings.
Eine Halte- und Indexierungsvorrichtung laut der vorliegenden Erfindung ist zur Integration in eine Stellvorrichtung von Uhren, insbesondere von Armbanduhren, gestaltet. Wie aus den Abbildungen 1a, 1b, und 1c, sowie 1d, 1e, und 1f ersichtlich, weist eine derartige Halte- und Indexierungsvorrichtung eine Buchse 1 auf, die in einer Öffnung des Uhrgehäuses der Uhr, in welche die Vorrichtung integriert werden soll, fest angebracht ist. Innerhalb der Buchse 1 ist eine Achse 3 sowohl axial verschiebbar als auch drehbar gelagert, wobei die Achse 3 innerhalb der Buchse 1 und an ihrem ins Uhrinnere gerichteten Ende eine Achsstange 3.1 geringeren Durchmessers sowie an ihrem zur Uhraußenseite gerichteten Ende einen Achskopf größeren Durchmessers aufweist, so daß sie am Übergang zwischen Achsstange und Achskopf eine Achsschulter 3.2 besitzt. Die Vorrichtung besitzt zudem ein am ins Uhrinnere gerichteten Ende der Achsstange 3.1 der Achse 3 angebrachtes Übermittlungsorgan 7, 8, welches den Antrieb eines im Uhrinneren befindlichen, in den Abbildungen 1a bis 1f nicht dargestellten Uhrteils erlaubt, sowie zumindest ein elastisches Element 4, welches eine in axialer Richtung der Achse 3 wirkende Vorspannkraft ausübt. Aus
Die Halte- und Indexierungsvorrichtung zeichnet sich dadurch aus, daß sie einen an besagter Achse 3 axial gleitend angebrachten Indexierungsring 6 mit einer Indexierungszahnung 6.1 besitzt. Der Indexierungsring 6 weist einen rohrförmigen Abschnitt 6.2 auf, welcher die Achsstange 3.1 umfassend in der Buchse 1 gleitend gelagert ist. Dabei schließt das in Richtung des Uhräußeren weisende Ende des rohrförmigen Abschnitt 6.2 in der Normallage der Vorrichtung, welche in den Abbildungen 1a, 1b, und 1c wiedergegeben ist, bündig mit der besagten Buchsschulter ab und liegt daher an dem vorgenannten Beilagring 5 an, welcher seinerseits von der Spiralfeder 4 gegen die Buchsschulter der Buchse 1 gedrückt wird. Allerdings erlaubt diese Ausgestaltung eine gleitende Bewegung des Indexierungsrings 6 und damit auch des Beilagrings 5 in Richtung des Uhräußeren, soweit hierfür eine die Vorspannkraft der Spiralfeder 4 übersteigende Kraft aufgewendet wird.The holding and indexing device is characterized in that it has an axially slidably mounted on said
In diesem Zusammenhang ist zu erwähnen, daß die Buchse 1 am ins Uhrinnere gerichteten Ende eine gezahnte Endfläche aufweist, wobei die Höhe der Endflächenzähne 1.1, respektive die Tiefe der Einkerbungen 1.2 zwischen den Endflächenzähnen 1.1 an besagter gezahnten Endfläche größer als die Dicke des Indexierungsrings 6 und der zugehörigen Indexierungszahnung 6.1 ist. Der Indexierungsring 6 ist damit durch Eingriff seiner Indexierungszahnung 6.1 in die besagte gezahnte Endfläche der Buchse 1 verdrehungssicher axial gleitend an besagter Achse 3 angebracht, wobei der Hub 6.3 der axialen Beweglichkeit dem Unterschied zwischen der Höhe der Endflächenzähne 1.1 und der Dicke des Indexierungsrings 6 entspricht.In this connection, it should be mentioned that the
Gleichzeitig weist das besagte Übermittlungsorgan 7, 8 an seiner in Richtung des Indexierungsrings 6 weisenden Seitenfläche eine Seitenzahnung 7.1 auf, welche durch die Wirkung der Vorspannkraft des elastischen Elements, also in der Ausführungsform der Abbildungen 1a bis 1f durch die Wirkung der Spiralfeder 4, mit der besagten Indexierungszahnung 6.1 in Eingriff steht. Dies ist, wie oben erläutert, daher der Fall, insofern der Indexierungsring 6 über dessen rohrförmigen Abschnitt 6.2, der am Beilagring 5 anliegt, von der Spiralfeder 4 in Richtung des Uhrinneren, und somit in Richtung der Seitenzahnung 7.1, 8.1 des Übermittlungsorgans 7, 8 vorbeaufschlagt wird. Die radiale Lage der Seitenzahnung 7.1 des Übermittlungsorgans 7 ist entsprechend der Lage der die Buchse 1 radial überragenden Indexierungszahnung 6.1 gewählt, um einen Eingriff beider Zahnungen zu ermöglichen. Die Indexierungszahnung 6.1 des Indexierungsrings 6 und die Seitenzahnung 7.1 des Übermittlungsorgans 7, 8 sind zudem derart gestaltet, daß in zumindest einer Drehrichtung der Achse 3 durch eine Krafteinwirkung einer vordefinierten Größe auf den Indexierungsring 6 ein Auskuppeln zwischen der Indexierungszahnung 6.1 und der Seitenzahnung 7.1 bewirkt und dadurch eine Positionsindexierung des besagten Uhrteils 22 erlaubt wird. Auf Grund der entsprechend gewählten Länge des rohrförmigen Abschnitts 6.2, an dessen ins Uhrinnere gerichteten Ende radial umfassend die Indexierungszahnung 6.1 angebracht ist, sowie auf Grund der Vorspannkraft der Spiralfeder 4 ragt das ins Uhrinnere gerichtete Ende des Indexierungsrings 6, insbesondere die Indexierungszahnung 6.1 in der Normallage der Vorrichtung etwas über die gezahnte Endfläche der Buchse 1 hinaus und greift dadurch in die Seitenzahnung 7.1 des Übermittlungsorgans 7, 8 ein, wobei die Indexierungszahnung 6.1 die Buchse 1 vorzugsweise auch radial überragt, während in der ausgekuppelten Lage der Vorrichtung das ins Uhrinnere gerichtete Ende des Indexierungsrings 6, respektive die Indexierungszahnung 6.1 bündig mit der gezahnten Endfläche der Buchse 1 abschließt. Die Normallage der Vorrichtung ist beispielhaft in den Abbildungen 1b und 1c dargestellt.At the same time, the said
Allgemein ist weiter anzumerken, daß die Indexierungszahnung 6.1 des Indexierungsrings 6 vorzugsweise merklich rechteckförmige Zähne aufweist, während die mit der Indexierungszahnung 6.1 in Eingriff stehende Seitenzahnung 7.1, 8.1 an der in Richtung des Indexierungsrings 6 weisenden Seitenfläche des besagten Übermittlungsorgans 7, 8 aus einer in eine Drehrichtung gegen jegliche Verdrehung sichernden ersten Breguetzahnung 7.1 bzw. ein ähnlich geformte Sägezahnung oder aus einer eine bidirektionale Verdrehung erlaubenden Dreieckszahnung 8.1 besteht.In general, it should further be noted that the indexing toothing 6.1 of the
In der ersten Ausführungsform einer Halte- und Indexierungsvorrichtung laut der vorliegenden Erfindung, welche in den Abbildungen 1a bis 1f dargestellt ist, besteht die mit den rechteckförmigen Zähnen der Indexierungszahnung 6.1 in Eingriff stehende Seitenzahnung 7.1 an der in Richtung des Indexierungsrings 6 weisenden Seitenfläche des besagten Übermittlungsorgans 7, 8 aus einer in eine Drehrichtung gegen jegliche Verdrehung sichernden ersten Breguetzahnung 7.1.In the first embodiment of a holding and indexing device according to the present invention shown in Figures 1a to 1f is, with the rectangular teeth of the indexing 6.1 engaging side teeth 7.1 at the pointing in the direction of the
In dieser Ausführungsform ist das Übermittlungsorgan 7, 8 derart ausgestaltet, daß es einen an der Achse 3 fest angebrachten Mitnehmertrieb 8 und eine um die Achse 3 drehbar gelagerte Mitnehmerscheibe 7 aufweist, so wie dies insbesondere aus den Abbildungen 1c und 1d hervorgeht. Der Mitnehmertrieb 8 kann insbesondere mittels einer konischen Schraube 9 am ins Uhrinnere der Uhr gerichteten Ende der Achsstange 3.1 befestigt werden. Zwischen dem Mitnehmertrieb 8 und der Mitnehmerscheibe 7 ist eine Kupplung in Form einer auf der in Richtung des Mitnehmertriebs 8 weisenden Seitenfläche der Mitnehmerscheibe 7 angeordneten zweiten Breguetzahnung 7.2 und einer mit dieser zweiten Breguetzahnung 7.2 in Eingriff stehenden Mitnehmerzahnung 8.2 auf dem Mitnehmertrieb 8 angebracht. Die mit der Indexierungszahnung 6.1 in Eingriff stehende Seitenzahnung 7.1, 8.1 an der in Richtung des Indexierungsrings 6 weisenden Seitenfläche des besagten Übermittlungsorgans 7, 8 besteht in diesem Falle also aus einer in eine Drehrichtung gegen jegliche Verdrehung sichernden ersten Breguetzahnung 7.1, welche auf der in Richtung des Indexierungsrings 6 weisenden Seitenfläche der Mitnehmerscheibe 7 angeordnet ist.In this embodiment, the
Die erste - 7.1 und zweite Breguetzahnung 7.2 sind dabei so an der Mitnehmerscheibe 7 angeordnet, daß bei Einrasten zwischen der zweiten Breguetzahnung 7.2 der Mitnehmerscheibe 7 und der Mitnehmerzahnung 8.2 des Mitnehmertriebs 8 während dessen Antriebs in eine Drehrichtung die erste Breguetzahnung 7.1 der Mitnehmerscheibe 7 auskuppelt, das heißt ihre sägezahnförmige Zahnung über die Indexierungszahnung 6.1 des Indexierungsrings 6 gleitet, indem das vom Mitnehmertrieb 8 über die Mitnehmerscheibe 7 auf den Indexierungsring 6 ausgeübte Drehmoment eine Kraft bewirkt, welche den Indexierungsring 6 um den Hub 6.3 in Richtung des Uhräußeren verschiebt und die Spiralfeder 4 entgegen deren Vorspannkraft zusammendrückt. Dies erlaubt eine Indexierung während des Einstellvorgangs des beweglichen Uhrteils 22.The first - 7.1 and second Breguetzahnung 7.2 are arranged on the
Umgekehrt erfolgt während des Antriebs des Mitnehmertriebs 8 in die entgegengesetzte Drehrichtung ein Gleiten der Mitnehmerzahnung 8.2 des Mitnehmertriebs 8 über die zweite Breguetzahnung 7.2 der Mitnehmerscheibe 7, insofern die Achse 3 hierbei auf Grund der durch das Drehmoment entfalteten Kraft in axialer Richtung entgegen der Vorspannkraft der Spiralfeder 4 und unter deren Komprimierung in Richtung des Uhrinneren verschoben wird, wobei die Indexierungszahnung 6.1 des Indexierungsrings 6 in die erste Breguetzahnung 7.1 der Mitnehmerscheibe 7 einrastet und dadurch die Mitnehmerscheibe 7 gegen jegliche Verdrehung in diese Drehrichtung sichert. Dies erlaubt eine Sicherung des beweglichen Uhrteils 22 gegen jegliche Verdrehung in der dieser Drehrichtung der Mitnehmerscheibe 7 entsprechenden Richtung.Conversely, during the drive of the
In Zusammenhang mit der ersten Ausführungsform einer Halte- und Indexierungsvorrichtung laut der vorliegenden Erfindung sei, in Verbindung mit den Abbildungen 1a bis 1f, noch darauf verwiesen, daß das oben erwähnte, zumindest eine elastische Element 4, 10, welches eine in axialer Richtung der Achse 3 wirkende Vorspannkraft ausübt, hier als eine zwischen der Achse 3 und dem Indexierungsring 6 angeordnete Spiralfeder 4 ausgebildet ist. Laut

Insbesondere weist die Stellvorrichtung, wie vor allem aus den Abbildungen 2c und 2d ersichtlich ist, einen fest an der Achse 3 der Halte- und Indexierungsvorrichtung angebrachten äußeren Stellkörper 2, welcher die Einstellung des besagten Uhrteils 22 erlaubt, auf. Weiterhin ist im dargestellten Beispiel der äußere Stellkörper 2 als Stellkappe 2.2 mit einer Antriebszahnung 2.1 ausgebildet, welche mit einem Zahnkranz 21.1 eines Außendrehrings 21 der Uhr in Eingriff steht. Insofern der Benutzer der Uhr den Stellkörper 2 über den Außendrehring 21 bedient, wird der äußere Stellkörper 2 vorzugsweise mittels einer Haube 26 vor mechanischen Einflüssen geschützt, wobei die Haube 26 im dargestellten Anwendungsbeispiel einer Taucheruhr aus unten klarer werdenden Gründen mit Löchern 26.1 versehen ist. Die Uhr weist weiterhin, wie üblich, einen Gehäusering 23, in dem die Buchse 1 sowie die weiteren Teile der erfindungsgemäßen Halte- und Indexierungsvorrichtung, respektive die zugehörige Stellvorrichtung angebracht ist, sowie einen Gehäuseboden 24 und ein über dem Innendrehring 22 angeordneten, das Uhrinnere verschließendes Uhrglas 25 auf.In particular, the adjusting device, as can be seen in particular from Figures 2c and 2d, a fixedly attached to the
Zudem ist die Vorspannkraft zumindest eines elastischen Elements 4, 10, vorzugsweise der Spiralfeder 4, in Abhängigkeit von der effektiven Stirnfläche des Stellkörpers 2 bestimmt, um eine selbsttätige, axiale Positionsumschaltung der Stellvorrichtung in Abhängigkeit vom anliegenden Außendruck zu erlauben, so wie dies in allen Einzelheiten im Dokument

Umgekehrt erfolgt bei Drehung des Außendrehrings 22 durch den Benutzer der Uhr entgegen dem Uhrzeigersinn eine Drehung des äußeren Stellkörpers 2, der Achse 3, sowie des Mitnehmertriebs 8, vom Uhräußeren aus betrachtet, im Uhrzeigersinn. Dies bewirkt, wie ebenfalls aus

Weiterhin besteht die eingangs erwähnte, mit der Indexierungszahnung 6.1 in Eingriff stehende Seitenzahnung 7.1 8.1 an der in Richtung des Indexierungsrings 6 weisenden Seitenfläche des besagten Übermittlungsorgans 7, 8 in dieser Ausführungsform der Vorrichtung aus einer eine bidirektionale Verdrehung erlaubenden Dreieckszahnung 8.1 auf der in Richtung des Indexierungsrings 6 weisenden Seitenfläche des Mitnehmertriebs 8, so wie etwa aus den Abbildungen 1a und 1b ersichtlich. Die rechteckigen Zähne der Indexierungszahnung 6.1 des Indexierungsrings 6 weisen hierbei ebenfalls eine dementsprechende seitliche Abschrägung auf.Furthermore, there is the above-mentioned, with the indexing 6.1 engaged side teeth 7.1 8.1 at the facing in the direction of
Die Halte- und Indexierungsvorrichtung laut der zweiten Ausführungsform funktioniert in Analogie zur ersten Ausführungsform, allerdings wird bei der zweiten Ausführungsform der Vorrichtung nur ein Halten des beweglichen Uhrteils 22 in der eingestellten Position sowie eine Indexierung während des Einstellvorgangs angestrebt und verwirklicht, jedoch keine Sicherung des beweglichen Uhrteils 22 gegen eine Verstellung bei Drehung der zugehörigen äußeren Stellkrone 2, respektive der Achse 3 in eine gegebene Drehrichtung. Im Gegenteil ist es bei dieser Vorrichtung möglich, das beweglichen Uhrteil 22 bei Drehung der zugehörigen äußeren Stellkrone 2, respektive der Achse 3 in beide Drehrichtungen zu verstellen.The holding and indexing apparatus according to the second embodiment operates in analogy to the first embodiment, however, in the second embodiment of the apparatus, only holding of the
Es wäre natürlich in einer nicht dargestellten, alternativen Ausführungsform ebenfalls möglich, die Indexierungszahnung 6.1 sowie die mit dieser in Eingriff stehende Seitenzahnung 7.1 8.1 der Vorrichtung laut der zweiten Ausführungsform analog zu der Vorrichtung laut der ersten Ausführungsform zu gestalten und damit ebenfalls eine Sicherung des beweglichen Uhrteils 22 gegen eine Verstellung bei Drehung der zugehörigen äußeren Stellkrone 2, respektive der Achse 3 in eine gegebene Drehrichtung zu erreichen.Of course, it would also be possible in an alternative embodiment, not shown, the indexing toothing 6.1 as well as the side toothing 7.1 8.1 of the device according to the second embodiment which is in engagement therewith to make analogous to the device according to the first embodiment and thus also to achieve a backup of the
Umgekehrt kann die Indexierungszahnung 6.1 sowie die mit dieser in Eingriff stehende Seitenzahnung 7.1 8.1 der Vorrichtung laut der ersten Ausführungsform analog zu der Vorrichtung laut der zweiten Ausführungsform gestaltet werden, so daß eine zugehörige, selbsttätig umschaltende Stellvorrichtung bidirektional betätigt werden könnte.Conversely, the Indexierungszahnung 6.1 and the engaging with this side teeth 7.1 8.1 of the device according to the first embodiment can be designed analogous to the device according to the second embodiment, so that an associated, automatically switching actuator could be operated bidirectionally.

Im Übrigen ist es dem Fachmann im Lichte der obigen Beschreibung klar, daß das besagte bewegliche Uhrteil 22 der Uhr, welches mittels der Stellvorrichtung eingestellt sowie dessen Position mittels der Halte- und Indexierungsvorrichtung gehalten und/oder gesichert und dessen Positioneinstellung indexiert wird, in kinematischer Verbindung mit dem besagten Übermittlungsorgan 7, 8 steht und aus verschiedensten Teilen einer Uhr bestehen kann. Insbesondere kann dieses bewegliche Uhrteil 22 aus der Gruppe beinhaltend einen Innendrehring, eine Datumsscheibe, eine Weltzeitscheibe, eine Mondscheibe, eine Weckerscheibe, eine Tachymeterscheibe, und eine für diverse Zwecke benutzbare Indexierungszeigerscheibe gewählt werden, so daß die Erfindung nicht auf die explizit dargestellten Beispiele beschränkt ist.Incidentally, in the light of the above description, it will be apparent to those skilled in the art that said
Eine derartige Halte- und Indexierungsvorrichtung, respektive eine zugehörige Stellvorrichtung ist insbesondere bei Taucheruhren von Nutzen, da in diesem Falle eine ungewollte Verstellung des Innendrehringes 22, vor allem in die Richtung, in welcher der Innendrehring 22 eine längere Tauchzeit als tatsächlich richtig anzeigen würde, für die Sicherheit des Tauchers von Bedeutung wäre und vermieden werden muß. Dies ist mittels einer erfindungsgemäßen Halte- und Indexierungsvorrichtung möglich.Such a holding and indexing device, respectively an associated adjusting device is particularly useful in divers watches, since in this case an unwanted adjustment of the inner
