Description

Die Erfindung bezieht sich auf eine Repetieruhr mit einer manuell spannbaren Feder, durch deren Entspannung eine Achse aus einer Spannposition in eine Ruheposition drehbar antreibbar ist, mit einem von der Achse drehbar antreibbaren ersten Rechen zur Betätigung eines ersten Schlagwerkes, sowie mit einem von dem ersten Schlagwerk antreibbaren ersten Hammer, von dem eine erste Tonfeder anschlagbar ist, wobei in einem ersten Teil des Entspann-Bewegungswegs der Achse aus der Spannposition in die Ruheposition der erste Rechen und im zweiten Teil dieses Entspann-Bewegungswegs ein zweiter Rechen zur Betätigung eines zweiten Schlagwerks von der Achse drehbar antreibbar ist, und vom zweiten Rechen ein zweites Schlagwerk betätigbar ist, durch das ein zweiter Hammer eine zweite Tonfeder anschlagend antreibbar ist und wobei der Drehantrieb zwischen dem zweiten Rechen und der Achse durch eine zweite Kupplungsvorrichtung einkuppelbar ist.The invention relates to a repeater watch with a manually tensionable spring, by the relaxation of which an axis can be rotatably driven from a tensioned position into a rest position, with a first rake rotatable from the axis for actuating a first striking mechanism, and with one of the first striking mechanism Drivable first hammer, from which a first gong can be struck, the first rake in a first part of the relaxation movement path of the axis from the clamping position to the rest position and in the second part of this relaxation movement path a second rake for actuating a second percussion mechanism from the Axis can be rotatably driven, and a second hammer mechanism can be actuated by the second rake, by means of which a second hammer can be driven to strike a second gong and the rotary drive can be engaged between the second rake and the axis by a second coupling device.

Bei derartigen Repetieruhren besteht das Problem, daß insbesondere dann, wenn sie als Armbanduhren ausgebildet sind, nur wenig Einbauraum zur Verfügung steht, um das Repetierwerk im Uhrgehäuse unterzubringen.The problem with repeater watches of this type is that, particularly if they are designed as wristwatches, there is little installation space available for accommodating the repeater mechanism in the watch case.

Aus der CH-A-9962 ist eine Repetieruhr bekannt, bei der durch manuelles Spannen der Feder eines Repetierwerkes gleichzeitig der Stundenrechen betätigt und die Stundenschläge ausgelöst werden. Durch das anschließende Entspannen der Feder löst das Repetierwerk die Viertelstunden- und Minutenschläge aus. Dabei ist der zeitliche Abstand zwischen dem Auslösen der Stundenschläge und dem Beginn der Viertelstundenschläge abhängig von der Freigabe des Spannhebels durch die Bedienperson.A repeater watch is known from CH-A-9962, in which the hourly rake is actuated and the hourly strikes are triggered by manual tensioning of the spring of a repeater mechanism. By then releasing the spring, the repeater unit triggers the quarter-hour and minute strikes. The time interval between the triggering of the hourly strikes and the start of the quarterly strikes depends on the release of the tension lever by the operator.

Aus der CH-A-7905 ist eine Repetieruhr der eingangs genannten Art bekannt, bei der am Ende des ersten Teils des Entspannbewegungswegs, in dem die Stunden angeschlagen werden, der Drehantrieb sofort mit dem zweiten Rechen zum Anschlagen der Viertelstunden und Minuten gekuppelt wird. Dabei muß immer der volle Bewegungsweg für alle Viertelstundenschläge absolviert werden unabhängig davon, ob auch nur zwei oder ein Viertelstundenschlag ausgelöst wird. Dadurch ist die Pause zwischen den Stunden- und den Viertelstundenschlägen unterschiedlich entsprechend der momentanen Viertelstundenposition.From CH-A-7905 a repeater watch of the type mentioned is known, in which at the end of the first part of the relaxation movement path in which the hours are struck, the rotary drive is immediately coupled to the second rake for striking the quarter hours and minutes. The full path of movement must always be completed for all quarter-hour strikes, regardless of whether even two or a quarter-hour strikes are triggered. As a result, the pause between the hourly and quarter-hour beats differs according to the current quarter-hour position.

Aufgabe der Erfindung ist es daher, eine Repetieruhr der eingangs genannten Art zu schaffen, die derart ausgebildet ist, daß ein Anschlagen unterschiedlicher Töne erfolgen kann, wobei ihr Aufbau sowohl einfach als auch wenig Bauraum erfordernd ausgebildet ist, wobei durch das Repetitionswerk hintereinander die Stunden, die Viertelstunden und die Minuten angeschlagen werden und der Beginn des Anschlagens der Viertelstunden sowie der Minuten jeweils immer exakt zu einem gleichen Zeitpunkt nach dem Beginn des Anschlagens der Stunden erfolgt.The object of the invention is therefore to provide a repeater clock of the type mentioned at the outset, which is designed in such a way that different tones can be struck, its construction being simple and requiring little installation space, with the repetition mechanism successively indicating the hours, the quarter hours and the minutes are struck and the beginning of the striking of the quarter hours and the minutes always occurs at exactly the same time after the start of the striking of the hours.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Drehantrieb zwischen dem ersten Rechen und der Achse am Ende des ersten Teils des Entspann-Bewegungswegs der Achse durch eine erste Kupplungsvorrichtung entkuppelbar und der Drehantrieb zwischen dem zweiten Rechen und der Achse am Beginn des zweiten Teils des Entspann-Bewegungswegs der Achse durch die zweite Kupplungsvorrichtung einkuppelbar sein kann.This object is achieved in that the rotary drive between the first rake and the axle at the end of the first part of the relaxation movement path of the axis can be uncoupled by a first coupling device and the rotary drive between the second rake and the axle at the beginning of the second part of the relaxation Movement path of the axis can be engaged by the second coupling device.

Durch diese Ausbildung wird es bei äußerst geringem Bauraumerfordernis möglich, durch das erste Schlagwerk zuerst die Stunden anschlagen zu lassen, während anschließend vom zweiten Schlagwerk z. B. die Minuten angeschlagen werden. Der Antrieb geht für beide Schlagwerke gemeinsam von der Achse aus.This design makes it possible with extremely small installation space to let the hours strike first by the first striking mechanism, while the second striking mechanism then z. B. the minutes are struck. The drive for both striking mechanisms comes from the axis together.

Vorzugsweise besitzt der Drehantrieb zwischen dem ersten Rechen und der Achse ein frei drehbar auf der Achse gelagertes, den ersten Rechen antreibendes Bauteil, das durch die erste Kupplungsvorrichtung drehfest mit der Achse verbindbar ist. Eine einfach aufgebaute und leicht betätigbare Kupplung wird dadurch gebildet, daß die erste Kupplungsvorrichtung eine Raste aufweist, die radial in eine Ausnehmung an der zylindrischen Mantelfläche der Achse eine drehfeste Verbindung erzeugend einrastbar und am Ende des zweiten Teils des Entspann-Bewegungswegs der Achse radial aus der Ausnehmung heraus bewegbar antreibbar ist, wobei an dem auf der Achse frei drehbar gelagerten ersten Bauteil ein um eine zur Achse parallele Schwenkachse schwenkbarer Auskupplerhebel gelagert ist, an dessen einem freien Ende die Raste angeordnet ist und der einen in etwa radial nach außen vorstehenden Auskupplerfinger besitzt, der am Ende des ersten Teils des Entspann-Bewegungswegs an einem Anschlag anschlagbar und seine Raste aus der Ausnehmung der Achse bewegend schwenkbar ist.The rotary drive between the first rake and the axis preferably has a component which is freely rotatably mounted on the axis and drives the first rake and which can be connected to the axis in a rotationally fixed manner by the first coupling device. A simply constructed and easy-to-operate coupling is formed in that the first coupling device has a detent which can be latched radially into a recess on the cylindrical lateral surface of the axis, producing a non-rotatable connection, and radially at the end of the second part of the relaxation movement path of the axis Recess is movably drivable, on the first component, which is freely rotatable on the axis, a decoupling lever which is pivotable about a pivot axis parallel to the axis is mounted, on one free end of which the catch is arranged and which has an approximately radially outwardly projecting decoupling finger, which can be struck at the end of the first part of the relaxation movement path and its catch can be pivoted out of the recess in the axis.

Besonders wenige Bauteile sind erforderlich, wenn das frei drehbar auf der Achse gelagerte erste Bauteil der scheibenförmig ausgebildete erste Rechen ist, der an seinem radial umlaufenden Randbereich Zähne aufweist, durch die ein erster Schöpfer des ersten Schlagwerks schwenkbar antreibbar ist.Particularly few components are required if the first component of the is a disc-shaped first rake, which has teeth on its radially circumferential edge region, through which a first creator of the first striking mechanism can be pivotably driven.

Der Drehantrieb kann in einfacher Ausgestaltung zwischen dem zweiten Rechen und der Achse ein frei drehbar auf der Achse gelagertes, den zweiten Rechen antreibendes Bauteil besitzen, das durch die zweite Kupplungsvorrichtung drehfest mit der Achse verbindbar ist.In a simple embodiment, the rotary drive can have, between the second rake and the axle, a component which is freely rotatably mounted on the axle and drives the second rake and which can be connected to the axle in a rotationally fixed manner by the second coupling device.

Ein sicheres Einkuppeln der zweiten Kupplungsvorrichtung zu immer exakt demselben Zeitpunkt bei Ablauf des Repetierwerks wird dadurch erreicht, daß die zweite Kupplungsvorrichtung ein Klemmrichtgesperre ist, durch das eine drehfeste Verbindung zwischen Achse und zweitem Bauteil während des Entspann-Bewegungswegs vom Beginn seines zweiten Teils bis zur Ruheposition herstellbar ist.A safe engagement of the second coupling device at exactly the same time when the repeater works is achieved in that the second coupling device is a clamping directional lock, by means of which a rotationally fixed connection between the axle and the second component during the relaxation movement path from the beginning of its second part to the rest position can be produced.

Dabei kann in einfacher Weise der Sperrer des Klemmrichtgesperres ein Wälzkörper sein.The lock of the clamping directional lock can be a rolling element in a simple manner.

Ist der Wälzkörper in einer Gesperreausnehmung angeordnet, die in dem von dem zweiten Bauteil überdeckten Bereich der zylindrischen Mantelfläche der Achse radial nach außen offen ausgebildet ist und deren Tiefe in Entspann-Bewegungsrichtung der Achse von einem leicht geringerem Maß als dem Durchmesser des Wälzkörpers ausgehend sich vergrößert, so erfolgt in einer Drehrichtung der Achse zum gewünschten Zeitpunkt sicher ein Kuppeln von Achse und zweitem Bauteil und in der anderen Drehrichtung ebenfalls sicher ein freies Drehen der Achse.The rolling element is arranged in a locking recess which is designed to be radially open to the outside in the region of the cylindrical lateral surface of the axis covered by the second component and whose depth increases in the relaxation direction of movement of the axis from a slightly smaller dimension than the diameter of the rolling element , the axis and the second component are safely coupled in one direction of rotation of the axis at the desired time and the axis is also freely rotated in the other direction of rotation.

In einer einfach und wenige Bauteile aufweisenden Ausbildung kann die Gesperreausnehmung an einem kreisscheibenförmigen, koaxial drehfest an der Achse angeordneten Mitnehmer ausgebildet sein, dessen zylindrische Mantelfläche ein Gleitlager bildet, auf dem das zweite Bauteil mit einer zentrischen Bohrung drehbar gelagert ist, an deren zylindrischer Innenwand der Wälzkörper Achse und zweites Bauteil drehfest verbindend in Anlage bringbar ist. Um im ersten Teil des Entspann-Bewegungswegs sicher den Wälzkörper von der zylindrischen Innenwand der Bohrung des zweiten Bauteils wegzuhalten und ein Kuppeln zu verhindern, kann der Wälzkörper mittels einer Abstandsführung im ersten Teil des Entspann-Bewegungswegs der Achse in einem Abstand zur zylindrischen Innenwand der zentrischen Bohrung gehalten sein.In a simple and few components training, the locking recess can be formed on a circular disk-shaped, coaxially rotatably arranged driver, the cylindrical outer surface of which forms a slide bearing on which the second component is rotatably supported with a central bore, on the latter cylindrical inner wall of the rolling element axis and second component can be brought into contact in a rotationally fixed connection. In order to safely keep the rolling element away from the cylindrical inner wall of the bore of the second component in the first part of the relaxation movement path and to prevent coupling, the rolling element can be spaced in the first part of the relaxation movement path of the axis at a distance from the cylindrical inner wall of the central one Be borehole.

Dabei kann die Abstandsführung eine Gleitbahn ausweisen, die sich entlang des ersten Teils des Entspann-Bewegungswegs der Achse konzentrisch zur Achse erstreckt.The spacing guide can have a slideway that extends concentrically to the axis along the first part of the relaxation movement path of the axis.

Ist der Wälzkörper mit einem parallel zu Achse aus der Gesperreausnehmung herausragenden Ende an einem Gleitstück angeordnet, das in einer zur Achse senkrechten Ebene verschiebbar gelagert ist, und dessen Verschiebung radial nach außen im Bereich des ersten Teils des Entspann-Bewegungswegs der Achse durch die Gleitbahn begrenzt ist, entlang der eine Gleitfläche des Gleitstücks gleitbar geführt ist, so kann sich nach Verlassen des ersten Teils des Entspann-Bewegungswegs das Gleitstück mit dem Wälzkörper radial nach außen und der Wälzkörper sich in den Bereich der Gesperreausnehmung bewegen, in dem er zwischen der zylindrischen Innenwand der Bohrung des zweiten Bauteils und dem Boden der Gesperreausnehmung eingeklemmt wird und diese beiden Teile drehfest miteinander kuppelt.
Zur Leichtgängigkeit trägt bei, wenn die Gleitfläche des Gleitstücks eine der Krümmung der Gleitbahn entsprechende Krümmung besitzt.
The rolling element is arranged with an end projecting parallel to the axis from the locking recess on a sliding piece which is mounted so as to be displaceable in a plane perpendicular to the axis and whose displacement is limited radially outwards in the region of the first part of the relaxation movement path of the axis by the slideway is along which a sliding surface of the slider is slidably guided, so after leaving the first part of the relaxation movement path, the slider with the rolling element can move radially outwards and the rolling element can move into the area of the locking recess in which it is between the cylindrical inner wall the bore of the second component and the bottom of the locking recess is clamped and these two parts are coupled in a rotationally fixed manner.
Contribution to the smooth operation is made if the sliding surface of the sliding piece has a curvature corresponding to the curvature of the slideway.

In einfacher Ausbildung kann das zweite, den zweiten Rechen antreibende Bauteil ein Antriebszahnrad sein, das in einen Zahnsektor des um eine Schwenkachse schwenkbaren zweiten Rechens eingreift.In a simple embodiment, the second component driving the second rake can be a drive gearwheel which engages in a tooth sector of the second rake which can be pivoted about a pivot axis.

Dabei besitzt vorzugsweise der zweite Rechen eine konzentrisch zur Schwenkachse angeordnete Zahnreihe, durch deren Zähne ein zweiter Schöpfer des zweiten Schlagwerks schwenkbar antreibbar ist.The second rake preferably has a row of teeth arranged concentrically to the swivel axis, through the teeth of a second creator of the second striking mechanism is pivotally driven.

Die dargestellte Repetieruhr besitzt einen Aufzugshebel 1, der durch manuelle Beaufschlagung seines Betätigungsnockens 2 um eine Schwenkachse 3 entgegen dem Uhrzeigersinn schwenkbar ist, bis er mit einem Anschlagstift 4 an einer Stundenstaffel 5 in Anlage kommt. Die Stundenstaffel 5 ist um eine Achse 6 mit einer Umdrehung pro zwölf Stunden drehbar angetrieben und besitzt an ihrer radial umlaufenden Mantelfläche gleichmäßig verteilt zwölf Stufen, die spiralartig in ihrer Höhe ansteigend angeordnet sind. Je nach Stufe ist somit der Aufzugshebel 1 mehr oder weniger um seine Schwenkachse 3 schwenkbar. Durch diese Schwenkbewegung ist über einen konzentrisch zur Schwenkachse 3 am Aufzugshebel 1 angeordneten Zahnsektor 7 ein Aufzugstriebrad 8 drehbar antreibbar, das drehfest auf einer Achse 9 angeordnet ist. Eine spiralförmig die Achse 9 umschließende Zugfeder 10 ist mit ihrem inneren Ende an der Achse 9 befestigt, während sie mit ihrem äußeren Ende an einem drehfesten, konzentrisch die Achse 9 umschließenden Federhaus fest angeordnet ist. Auf der Achse 9 ist weiterhin ein kreisscheibenförmiger Stunden/Viertelstundenrechen 11 frei drehbar gelagert, der mittels einer ersten Kupplungsvorrichtung drehfest mit der Achse verbindbar ist. Der Stunden/Viertelstundenrechen 11 besitzt an seinem radial umlaufenden Rand im Uhrzeigersinn hintereinander eine Reihe von zwölf Stundenzähnen 12, eine erste Reihe von drei Viertelstundenzähnen 13 und eine zweite Reihe von drei Viertelstundenzähnen 14. Bei Drehung des Stunden/Viertelstundenrechens 11 entgegen dem Uhrzeigersinn ist durch die Stundenzähne 12 und durch die Viertelstundenzähne 13 ein Stundenschöpfer 15 und durch die Viertelstundenzähne 14 ein Viertelstundenschöpfer 16 schwenkbar antreibbar. Diese Drehbewegung des Stunden/Viertelstundenrechens 11 erfolgt, nachdem das Spannen der Zugfeder 10 durch manuelles Schwenken des Aufzugshebels 1 erfolgt war, durch die sich wieder entspannende Zugfeder 10.The repeater watch shown has an elevator lever 1, which is activated by manual actuation of its actuating cam 2 can be pivoted counterclockwise about a pivot axis 3 until it comes into contact with an hourly scale 5 with a stop pin 4. The hourly scale 5 is rotatably driven about an axis 6 with one revolution per twelve hours and has twelve stages on its radially circumferential circumferential surface, which are distributed evenly and are arranged in a spiral, increasing in height. Depending on the level, the elevator lever 1 can thus be pivoted more or less about its pivot axis 3. As a result of this pivoting movement, an elevator drive wheel 8, which is arranged in a rotationally fixed manner on an axis 9, can be rotatably driven via a tooth sector 7 arranged concentrically to the pivot axis 3 on the elevator lever 1. A tension spring 10 which spirally surrounds the axis 9 is fixed at its inner end to the axis 9, while its outer end is fixedly arranged on a rotationally fixed barrel concentrically surrounding the axis 9. A circular disk-shaped hour / quarter hour rake 11 is also freely rotatably mounted on the axis 9 and can be connected in a rotationally fixed manner to the axis by means of a first coupling device. The hour / quarter hour rake 11 has a row of twelve hour teeth 12, a first row of three quarter hour teeth 13 and a second row of three quarter hour teeth 14 on its radially circumferential edge in a clockwise direction Hour teeth 12 and through the quarter hour teeth 13 an hour creator 15 and through the quarter hour teeth 14 a quarter hour creator 16 can be pivoted. This rotary movement of the hour / quarter hour rake 11 takes place after the tensioning of the tension spring 10 has been carried out by manually pivoting the elevator lever 1, by means of the tension spring 10 which relaxes again.

Durch die Schwenkbewegung des Stundenschöpfers 15 ist über einen schwenkbaren Zwischenhebel 17 ein an seinem freien Ende einen Stundenhammer 18 tragender Stundenhammerhebel 19 derart schwenkbar antreibbar, daß der Stundenhammer 18 entgegen der Kraft der Feder 20 vor einer Stundentonfeder 21 wegbewegt wird.Due to the pivoting movement of the hourly scoop 15, an hour hammer lever 19 carrying an hour hammer 18 at its free end can be pivotably driven via a pivotable intermediate lever 17 in such a way that the hour hammer 18 is moved away from an hourly tone spring 21 against the force of the spring 20.

Nach Überrasten eines Stundenzahns 12 über den Stundenschöpfer 15 wird dann durch die Feder 20 der Stundenhammer 18 mit Schwung gegen die Stundentonfeder 21 bewegt und durch Anschlagen ein Ton erzeugt.After latching an hour tooth 12 over the hour creator 15, the hour hammer 18 is then moved by the spring 20 with momentum against the hour tone spring 21 and a tone is generated by striking.

Auf die gleiche Weise erfolgt durch die Schwenkbewegung des Viertelstundenschöpfers 16 über einen schwenkbaren Zwischenhebel 22 ein Wegschwenken eines an einem Viertelstundenhammerhebel 23 angeordneten Viertelstundenhammers 24 entgegen der Kraft einer Feder 25 von einer Viertelstundentonfeder 26.In the same way, the pivoting movement of the quarter-hour scoop 16 via a pivotable intermediate lever 22 causes a quarter-hour hammer 24 arranged on a quarter-hour hammer lever 23 to be pivoted away against the force of a spring 25 by a quarter-hour tone spring 26.

Nach Überrasten eines Viertelstundenzahns 14 über den Viertelstundenschöpfer 16 bewegt die Feder 25 den Viertelstundenhammer 24 mit Schwung gegen die Viertelstundentonfeder 26 und erzeugt durch Anschlagen einen Ton, der eine andere Tonhöhe besitzt als die Stundenfeder 21.After a quarter-hour tooth 14 has latched over the quarter-hour scraper 16, the spring 25 moves the quarter-hour hammer 24 with momentum against the quarter-hour tone spring 26 and generates a tone by striking which has a different pitch than the hour spring 21.

Die Stundenzähne 12 und die Viertelstundenzähne 13 besitzen die gleiche, gegenüber den Viertelstundenzähnen 14 geringere radiale Erstreckung.The hour teeth 12 and the quarter hour teeth 13 have the same radial extension compared to the quarter hour teeth 14.

Damit kann der Stundenschöpfer 15 sowohl durch die Stundenzähne 12 als auch durch die Viertelstundenzähne 13 schwenkbar angetrieben werden, während der in etwas größerem radialen Abstand zum Stunden/Viertelstundenrechen 11 angeordnete Viertelstundenschöpfer 16 nur durch die Viertelstundenzähne 14 antreibbar ist.The hour creator 15 can thus be pivotally driven both by the hour teeth 12 and by the quarter hour teeth 13, while the quarter hour creator 16 arranged at a somewhat greater radial distance from the hour / quarter hour rake 11 can only be driven by the quarter hour teeth 14.

Der Abstand von Stundenschöpfer 15 und Viertelstundenschöpfer 16 in Umfangsrichtung ist so, daß beim Anschlagen der Viertelstunden Doppelschläge durchgeführt werden.The distance from the hour creator 15 and quarter hour creator 16 in the circumferential direction is such that double strikes are carried out when the quarter hours are struck.

Dabei erfolgt erst ein Schwenkantrieb des Viertelstundenschöpfers 16 durch einen Viertelstundenzahn 14 und zeitlich kurz danach ein Schwenkantrieb des Stundenschöpfers 15 durch einen Viertelstundenzahn 13.First, the quarter-hour scoop 16 is pivoted by a quarter-hour tooth 14 and, shortly thereafter, the hour-scoop 15 is pivoted by a quarter-hour tooth 13.

Die Anzahl der Stundenschläge wird durch den Drehwinkel bestimmt, um den die Achse 9 durch die Schwenkbewegung des Aufzugshebels 1 und damit durch die Stellung der Stundenstaffel 5 verdreht wird.The number of hourly strikes is determined by the angle of rotation by which the axis 9 is rotated by the pivoting movement of the elevator lever 1 and thus by the position of the hourly scale 5.

Dabei ist für die Stundenschläge nur der dritte Teil dieses Schwenkwinkels relevant, da durch den ersten Teil die Schläge eines Minutenschlagwerks und durch den zweiten Teil die Viertelstundenschläge antreibbar sind.Only the third part of this swivel angle is relevant for the hourly strikes, since the strikes of a minute striking mechanism can be driven by the first part and the quarter-hour strikes by the second part.

Durch die erste Kupplungsvorrichtung und einen schwenkbaren Viertelverteiler 27 wird der Schwenkwinkel bestimmt, in dem die Viertelstundenzähne 13 und 14 den Stundenschöpfer 15 bzw. den Viertelstundenschöpfer 16 antreiben können.The first coupling device and a pivotable quarter distributor 27 determine the pivot angle at which the quarter-hour teeth 13 and 14 can drive the hour creator 15 and the quarter hour creator 16, respectively.

Die erste Kupplungsvorrichtung weist eine Raste 28 auf, die an einem Auskupplerhebel 29 angeordnet ist, der um eine zur Achse 9 parallele Schwenkachse 30 derart schwenkbar auf dem Stunden/Viertelstundenrechen 11 gelagert ist, daß die Raste 28 unter der Wirkung einer Feder 31 etwa radial sich eine radial nach außen offene Ausnehmung 31 einer Mitnehmerscheibe 32 einrasten und eine drehfeste Verbindung herstellen kann.The first coupling device has a catch 28 which is arranged on a decoupling lever 29 which is pivotably mounted on the hour / quarter hour rake 11 about a pivot axis 30 parallel to the axis 9 in such a way that the catch 28 is approximately radial under the action of a spring 31 can engage a recess 31 of a driving disk 32 which is open radially outwards and can produce a rotationally fixed connection.

Die Mitnehmerscheibe 32 ist koaxial fest mit der Achse 9 verbunden, so daß mittels der in die Ausnehmung 31 einrastenden Raste 28 eine drehfeste Verbindung zwischen Stunden/Viertelstundenrechen 11 und Achse 9 herstellbar ist.The drive plate 32 is coaxially fixed to the axis 9, so that a non-rotatable connection between hour / quarter hour rake 11 and axis 9 can be produced by means of the catch 28 which engages in the recess 31.

Der Auskupplerhebel 29 besitzt einen etwa radial hervorstehenden Auskupplerfinger 33, der beim Drehantrieb des Stunden/Viertelstundenrechens 11 entgegen dem Uhrzeigersinn nach einem bestimmten, sich an den die Stundenschläge bestimmenden Drehweg anschließenden Drehweg in eine Hakenausnehmung 34 des Viertelverteilers 27 eingreifen kann. Der Viertelverteiler 27 ist dann nur noch bis zur Anlage an einen Anschlag 35 verschwenkbar und beendet die drehfeste Kupplung zwischen Achse 9 und Stunden/Viertelstundenrechen 11, indem durch den vom Viertelverteiler 27 festgehaltenen Auskupplerfinger 33 der Auskupplerhebel 29 die Raste 28 aus der Ausnehmung 31 herausbewegend verschwenkt wird.The decoupler lever 29 has an approximately radially protruding decoupler finger 33, which rotates counterclockwise when the hour / quarter hour calculator 11 is rotated into a hook recess after a certain rotational path adjoining the rotational path determining the hourly shocks 34 of the quarter distributor 27 can intervene. The quarter distributor 27 can then only be pivoted up to the abutment against a stop 35 and ends the non-rotatable coupling between the axis 9 and hours / quarter hour rake 11 by pivoting the catch 28 out of the recess 31 by the decoupler fingers 33 held by the quarter distributor 27 becomes.

Der Viertelverteiler 27 besitzt vier etwa in Umfangsrichtung des Stunden/Viertelstundenrechens 11 hintereinander angeordnete Hakenausnehmungen 34, wobei jeweils eine Hakenausnehmung 34 einer Viertelstunde zugeordnet ist. Die entgegen dem Uhrzeigersinn erste Hakenausnehmung 34 entspricht der ersten Viertelstunde und die entgegen dem Uhrzeigersinn letzte Hakenausnehmung 34 der letzten Viertelstunde einer Stunde.The quarter distributor 27 has four hook recesses 34 arranged approximately one after the other in the circumferential direction of the hour / quarter hour calculator 11, one hook recess 34 in each case being assigned to a quarter of an hour. The counterclockwise first hook recess 34 corresponds to the first quarter of an hour and the counterclockwise last hook recess 34 corresponds to the last quarter of an hour.

Je nach der Schwenkstellung des Viertelverteilers 27 kommt eine Hakenausnehmung 34 in den Umlaufbereich des Auskupplerfingers 33, so daß dieser dort einhaken kann. Die Schwenkstellung des Viertelverteilers 27 wird durch einen Taster 36 bestimmt, der an einem Tastarm 37 des Viertelverteilers 27 angeordnet ist und eine Viertelstundenstaffel 38 abtastet.Depending on the pivoting position of the quarter distributor 27, a hook recess 34 comes into the circumferential area of the decoupler finger 33 so that it can hook there. The pivot position of the quarter distributor 27 is determined by a button 36, which is arranged on a probe arm 37 of the quarter distributor 27 and scans a quarter-hour scale 38.

Die Viertelstundenstaffel 38 ist um eine Achse 39 vom Uhrwerk mit einer Umdrehung pro drei Stunden drehbar angetrieben und besitzt gleichmäßig verteilt an ihrem Umfang drei jeweils vier Stufen aufweisende Staffeln 40. Die Stufen einer Staffel 40 haben spiralartig ansteigende Höhe und sind je einer Viertelstunde zugeordnet. Je nachdem, welche der Stufen vom Taster 36 abgetastet wird, kann der Viertelverteiler 27 mehr oder weniger verschwenken und die der abgetateten Viertelstundenstufe zugeordnete Hakenausnehmung 34 in den Bereich des Auskupplerfingers 33 bringen.The quarter-hour scale 38 is rotatably driven about an axis 39 by the clockwork at one revolution per three hours and has three graduations 40 each having four levels distributed evenly around its circumference. Depending on which of the stages is scanned by the button 36, the quarter distributor 27 can pivot more or less and bring the hook recess 34 associated with the quarter hour stage that has been scanned into the area of the decoupler finger 33.

Auf der Achse 9 ist weiterhin ein kreisscheibenförmiger Mitnehmer 42 drehfest angeordnet, dessen radial umlaufende zylindrische Mantelfläche ein Gleitlager bildet, auf dem ein Antriebszahnrad 41 mit einer zentrischen Bohrung 47 frei drehbar gelagert ist.On the axis 9, a circular disk-shaped driver 42 is arranged in a rotationally fixed manner, the radially rotating one cylindrical outer surface forms a slide bearing on which a drive gear 41 with a central bore 47 is freely rotatable.

Der Mitnehmer 42 besitzt an seiner zylindrischen Mantelfläche eine radial nach außen offene Gesperreausnehmung 43. Diese Gesperreausnehmung 43 ist stufenartig mit unterschiedlicher Tiefe ausgebildet, wobei die in der dem Uhrzeigersinn entgegengesetzten Richtung erste Stufe 44 im Uhrzeigersinn radial nach außen leicht ansteigende Tiefe besitzt.The driver 42 has on its cylindrical outer surface a radially outwardly open locking recess 43. This locking recess 43 is designed step-like with different depths, with the first step 44 in the counterclockwise direction having a radially outwardly slightly increasing depth in the clockwise direction.

Die Tiefe der zweiten Stufe 45 ist deutlich größer als die der ersten Stufe, wobei die zweite Stufe 45 eine etwa kreisförmige Mulde bildet.The depth of the second step 45 is significantly greater than that of the first step, the second step 45 forming an approximately circular trough.

Ein rollenartiger Wälzkörper 46 ragt axial zur Achse 9 in die Gesperreausnehmung 43 hinein. Der Durchmesser des Wälzkörpers 46 entspricht der Form der Mulde der zweiten Stufe 45 und ist um ein geringes Maß größer als die Tiefe der ersten Stufe 44. Dadurch liegt er, wenn er sich im Bereich der ersten Stufe 44 befindet, sowohl am Boden der ersten Stufe 44 als auch an der zylindrischen Innenwand der Bohrung 47 an und bildet ein Klemmrichtgesperre.A roller-like rolling element 46 projects axially into the locking recess 43 axially to the axis 9. The diameter of the rolling element 46 corresponds to the shape of the trough of the second step 45 and is slightly larger than the depth of the first step 44. As a result, when it is in the region of the first step 44, it lies both at the bottom of the first step 44 and on the cylindrical inner wall of the bore 47 and forms a clamping directional lock.

Dieses bewirkt, daß bei Drehung der Achse 9 und des Mitnehmers 42 im Uhrzeigersinn - das entspricht der Federspannrichtung der Zugfeder 10 - der Wälzkörper 46 sich in die Mulde der zweiten Stufe 45 bewegt und das Antriebszahnrad 41 von dem Mitnehmer 42 und der Achse 9 entkuppelt ist. Bei Drehung der Achse 9 entgegen dem Uhrzeigersinn kann sich der Wälzkörper 46 in den Bereich der ersten Stufe 44 bewegen und eine drehfeste Verbindung zwischen Mitnehmer 42 und Antriebszahnrad 41 herstellen.This causes that when the axis 9 and the driver 42 rotate clockwise - this corresponds to the spring tensioning direction of the tension spring 10 - the rolling element 46 moves into the trough of the second stage 45 and the drive gear 41 is uncoupled from the driver 42 and the axis 9 . When the axis 9 rotates counterclockwise, the rolling element 46 can move into the area of the first step 44 and establish a rotationally fixed connection between the driver 42 and the drive gear 41.

Damit wird mit der Drehbewegung der Achse 9 auch das Antriebszahnrad 41 mitgenommen.Thus, the drive gear 41 is taken along with the rotational movement of the axis 9.

Der Wälzkörper 46 ist mit seinem nach oben aus der Gesperreausnehmung 43 herausragenden Ende in einer Bohrung 48 eines scheibenartigen Gleitstücks 49 angeordnet, das auf der Oberfläche des Mitnehmers 42 in der zur Achse 9 senkrechten Ebene verschiebbar gelagert ist.The rolling element 46 is with its end projecting upwards out of the locking recess 43 in a bore 48 of a disc-like slider 49 is arranged, which is slidably mounted on the surface of the driver 42 in the plane perpendicular to the axis 9.

Das Gleitstück 49 besitzt an seiner radial nach außen gerichteten Seite eine kreissektorartige Gleitfläche 50, die entlang einer entsprechenden Gleitbahn 51 einer Abstandsführung 52 gleiten kann.On its radially outward side, the slider 49 has a circular sector-like sliding surface 50 which can slide along a corresponding slideway 51 of a spacer guide 52.

Die Gleitbahn 51 erstreckt sich konzentrisch zur Achse 9 um einen Bereich, der dem dritten Teil des Drehwinkels entspricht, um den die Achse 9 durch die Schwenkbewegung des Aufzugshebels 1 verdreht wird.The slideway 51 extends concentrically to the axis 9 by a region which corresponds to the third part of the angle of rotation about which the axis 9 is rotated by the pivoting movement of the elevator lever 1.

Durch die Gleitbahn 51 wird in diesem Bereich eine radiale Verschiebung des Gleitstücks 49 und damit auch des Wälzkörpers 46 derart begrenzt, daß der Wälzkörper 46 auch bei Drehung der Achse 9 im Uhrzeigersinn nicht zur Anlage an der zylindrischen Innenwand der Bohrung 47 gelangen und eine drehfeste Kupplung herstellen kann. Der Wälzkörper 46 wird dabei im Bereich der 2. Stufe 45 gehalten.Through the slideway 51 a radial displacement of the slider 49 and thus also the rolling element 46 is limited in such a way that the rolling element 46 does not come into contact with the cylindrical inner wall of the bore 47 even when the axis 9 rotates clockwise and a rotationally fixed coupling can manufacture. The rolling element 46 is held in the area of the second stage 45.

Während der Zeit, während der sich die Gleitfläche 50 entlang der Gleitbahn 51 bewegt, erfolgt der Antrieb des Stunden/Viertelstundenrechens 11 und damit das Anschlagen der Stunden und der Viertelstunden.During the time during which the sliding surface 50 moves along the slideway 51, the hour / quarter hour calculator 11 is driven and thus the hours and the quarter hours are struck.

Erst wenn die Gleitfläche 50 und damit auch die Gesperreausnehmung 43 aus dem Bereich der Gleitbahn 51 der Abstandsführung 52 sich herausbewegt, können das Gleitstück 49 und der Wälzkörper 46 sich wieder radial nach außen bewegen, wodurch sich der Wälzkörper 46 auch in die erste Stufe 44 der Gesperreausnehmung 43 hineinbewegen und eine drehfeste Verbindung zwischen Mitnehmer 42 und Antriebszahnrad 41 herstellen kann.Only when the sliding surface 50 and thus also the locking recess 43 moves out of the region of the sliding path 51 of the spacing guide 52 can the sliding piece 49 and the rolling element 46 move radially outward again, as a result of which the rolling element 46 also moves into the first step 44 of the Move locking recess 43 in and establish a rotationally fixed connection between driver 42 and drive gear 41.

Das Antriebszahnrad 41 greift in einen Zahnsektor 53 eines Minutenrechens 54 ein und schwenkt diesen um eine Schwenkachse 55. Der Minutenrechen 54 ist aus einer Position schwenkbar, die durch einen Taster 56 bestimmt wird, der zur Anlage an einer Minutenstaffel 57 gelangt. Die Minutenstaffel 57 besitzt eine Zahnreihe 58 mit vierzehn Zahnlücken, wobei jede Zahnlücke eine Minutenposition bedeutet. Durch Verschwenken der Minutenstaffel 57 um eine Schwenkachse 59 durch das Uhrwerk wird innerhalb einer Viertelstundenperiode die Anschlagstelle des Tasters 56 an der Zahnreihe 58 so verändert, daß der Minutenrechen 54 abhängig von dem Minutenstand des Uhrwerks mehr oder weniger weit schwenkbar von dem Antriebszahnrad 41 antreibbar ist.The drive gear 41 engages in a toothed sector 53 of a minute rake 54 and pivots it about a pivot axis 55. The minute rake 54 is made of a Position pivotable, which is determined by a button 56, which comes to rest on a minute scale 57. The minute series 57 has a row of teeth 58 with fourteen tooth gaps, each tooth gap representing a minute position. By pivoting the minute scale 57 about a pivot axis 59 through the clockwork, the stop point of the button 56 on the tooth row 58 is changed within a quarter of an hour period so that the minute rake 54 can be driven more or less pivotably by the drive gear 41 depending on the minute status of the clockwork.

Konzentrisch zur Schwenkachse 55 ist an dem Minutenrechen 54 eine Zahnreihe mit vierzehn Minutenzähnen 60 angeordnet, durch die ein Minutenschöpfer 61 schwenkbar antreibbar ist. Der Minutenschöpfer 61 ist um die gleiche Achse schwenkbar wie der Viertelstundenschöpfer 16 und treibt ebenfalls den Zwischenhebel 22, den Viertelstundenhammerhebel 23 und den Viertelstundenhebel 24 an.A row of teeth with fourteen minute teeth 60 is arranged concentrically to the pivot axis 55 on the minute rake 54, by means of which a minute scraper 61 can be pivotably driven. The minute scraper 61 is pivotable about the same axis as the quarter hour scoop 16 and also drives the intermediate lever 22, the quarter hour hammer lever 23 and the quarter hour lever 24.

Die Minuten einer Viertelstunde werden somit auch an der Viertelstundentonfeder 26 angeschlagen.The minutes of a quarter of an hour are thus struck at the quarter-hour spring 26.

Durch dieses Repetitionswerk werden somit hintereinander die Stunden, die Viertelstunden und die Minuten angeschlagen. Der Beginn des Anschlagens der Viertelstunden sowie der Minuten ist jeweils immer exakt zu einem gleichen Zeitpunkt nach dem Beginn des Anschlagens der Stunden.With this repetition work, the hours, the quarter hours and the minutes are struck one after the other. The start of the quarter-hour and the minute is always at exactly the same time after the start of the hour.
