Abstract

The timepiece has a two-directional corrector mechanism provided for a display device, which displays a time related quantity e.g. date. The display device is actuated by a control lever (14), where the lever is controlled by a cam on which the control lever abuts. A correction device e.g. annular cam, is actuated by a control stem (42) in a display device correction phase. The correction device moves the control lever out of a path of the cam. The control lever normally abuts in a normal operating phase of the timepiece.

Description

La présente invention concerne une pièce d'horlogerie comprenant un mécanisme de correction pour un dispositif d'affichage d'une grandeur temporelle. Plus précisément, la présente invention concerne une telle pièce d'horlogerie comprenant un mécanisme pour la correction bidirectionnelle d'un dispositif d'affichage d'une grandeur temporelle tel qu'un mécanisme de quantième.The present invention relates to a timepiece comprising a correction mechanism for a display device of a temporal magnitude. More specifically, the present invention relates to such a timepiece comprising a mechanism for the bidirectional correction of a display device of a temporal magnitude such as a date mechanism.

Les dispositifs d'affichage d'une grandeur temporelle tels que les mécanismes de quantième sont, pour une partie d'entre eux, basés sur des systèmes de bras de commande qui suivent le profil d'une came et qui, quotidiennement, actionnent un organe indicateur de quantième. Classiquement, en un endroit de son profil, la came présente un flanc abrupt qui marque le passage du dernier jour d'un mois donné au premier jour du mois suivant. La présence, en un endroit du profil de la came, de ce flanc abrupt pose un problème lorsqu'on veut effectuer une correction, par exemple de l'indication du quantième, dans le sens anti-horaire. En effet, lorsqu'on veut corriger l'indication du quantième dans le sens horaire, autrement dit lorsqu'on veut passer d'un quantième donné à un quantième supérieur d'une unité au quantième précédent, on ne rencontre pas de difficulté. Le bras de commande suit le profil de la came et commande pas à pas l'avance en marche avant de l'organe indicateur de quantième. Lorsque le bras de commande arrive à hauteur du flanc abrupt du profil de la came marquant le passage du dernier quantième d'un mois donné au premier quantième du mois suivant, il tombe, faisant avancer d'un pas l'organe indicateur de quantième. Il n'en va pas de même lorsqu'on cherche à faire reculer l'organe indicateur de quantième. En effet, dans ce cas survient un moment où le bras de commande vient taper contre le flanc abrupt du profil de la came et se bloque. Il devient alors impossible de corriger l'indication du quantième.The display devices of a time scale such as date mechanisms are, for a part of them, based on control arm systems which follow the profile of a cam and which, on a daily basis, actuate an organ date indicator. Conventionally, at one point of its profile, the cam has an abrupt flank marking the passage from the last day of a given month to the first day of the following month. The presence, in one place of the profile of the cam, of this abrupt flank poses a problem when one wants to make a correction, for example of the indication of the date, in the anti-clockwise direction. Indeed, when we want to correct the indication of the date in the clockwise direction, in other words when we want to go from a given date to a higher date of a unit to the previous date, we do not encounter any difficulty. The control arm follows the profile of the cam and controls step forward forward of the date indicator member. When the control arm reaches the steep side of the profile of the cam marking the passage of the last calendar of a given month to the first calendar of the following month, it falls, advancing by one step the date indicator organ. This is not the case when looking to roll back the date indicator organ. Indeed, in this case occurs a moment when the control arm is banging against the steep side of the profile of the cam and hangs. It becomes impossible to correct the indication of the date.

Pour remédier à ce problème, différentes solutions ont déjà été proposées. A titre d'exemple, on connaît par le document de brevet EP 0 851 321 au nom de Seiko Instruments Inc. une pièce d'horlogerie multifonction comprenant un levier de correction de la petite aiguille des heures qui pousse une partie de queue d'un marteau. Le marteau est alors pivoté dans le sens anti-horaire et amené dans un état dans lequel il n'est plus en contact avec une came d'actionnement. Le document Seiko ne décrit pas un mécanisme correcteur bidirectionnel comprenant un organe de correction en forme de came annulaire actionné par une tige de commande et permettant d'écarter, via une came de rappel sur laquelle il agit, le bras d'une bascule de commande de la came sur laquelle ce bras est normalement en appui.To remedy this problem, various solutions have already been proposed. For example, it is known from the patent document EP 0 851 321 on behalf of Seiko Instruments Inc. a multifunction timepiece including a small hour hand correction lever that pushes a tail portion of a hammer. The hammer is then rotated anti-clockwise and brought into a state in which it is no longer in contact with an actuating cam. The Seiko document does not describe a bi-directional corrective mechanism comprising an annular cam-shaped correction member actuated by a control rod and allowing to spread, via a return cam on which it acts, the arm of a control rocker of the cam on which this arm is normally supported.

On connaît également par le document de brevet EP 1 336 907 au nom de Richemont International S.A. un mécanisme d'actionnement pour un dispositif de mise à l'heure d'une pièce d'horlogerie. Plus précisément, le mécanisme d'actionnement comprend un anneau de commande disposé de manière concentrique par rapport au centre de la montre. En fonction de la position d'engagement d'une couronne, l'anneau de commande peut occuper deux positions radiales sous l'effet de l'action d'un levier coudé. Le document Richemont omet de mentionner que l'anneau de commande présente un profil de came sur son pourtour intérieur.It is also known from the patent document EP 1 336 907 on behalf of Richemont International SA an actuating mechanism for a time setting device of a timepiece. More specifically, the actuating mechanism comprises a control ring disposed concentrically with respect to the center of the watch. Depending on the position of engagement of a ring, the control ring can occupy two radial positions under the effect of the action of a bent lever. The Richemont document fails to mention that the control ring has a cam profile on its inner periphery.

On connaît aussi par le document de brevet CH 660 440 au nom de Dubois & Dépraz S.A., un mécanisme de quantième perpétuel dans lequel la grande bascule est levée par le levier d'une autre bascule. Le document Dubois & Dépraz ne décrit pas un mécanisme correcteur dans lequel le bras d'une bascule de commande est écarté de la came sur laquelle il est normalement en appui via une bascule de rappel qui coopère avec l'organe de correction en forme de came annulaire.It is also known from the patent document CH 660 440 in the name of Dubois & Dépraz SA, a perpetual calendar mechanism in which the large flip-flop is raised by the lever of another flip-flop. The document Dubois & Dépraz does not describe a corrective mechanism in which the arm of a control lever is spaced from the cam on which it is normally supported by a return lever which cooperates with the cam-shaped correction member annular.

On connaît enfin par le document de brevet CH 674 290 au nom de Roth un dispositif d'affichage mécanique de données de même qu'une pièce d'horlogerie équipée d'un tel dispositif. Dans l'un des modes de réalisation décrit dans ce document, on voit que lorsqu'une couronne est manoeuvrée à l'aide d'un poussoir, un levier à deux bras est déplacé, ce qui amène la denture de son râteau à entraîner un pignon. Ce document décrit bien un organe d'actionnement en forme de came annulaire. Il omet cependant de décrire l'actionnement d'une came de commande via une came de rappel qui coopère avec le profil de came prévu sur le pourtour intérieur de la came annulaire.Finally, we know from the patent document CH 674 290 in the name of Roth a mechanical data display device as well as a timepiece equipped with such a device. In one of the embodiments described in this document, it can be seen that when a crown is operated by means of a pusher, a lever with two arms is moved, which causes the toothing of its rake to cause a pinion. This document does describe an actuating member in the form of an annular cam. However, it fails to describe the actuation of a control cam via a return cam which cooperates with the cam profile provided on the inner periphery of the annular cam.

Au vu de ce qui précède, la présente invention a pour but de procurer une pièce d'horlogerie comprenant un nouveau type de mécanisme de correction d'un dispositif d'affichage par exemple du quantième permettant la correction de celui-ci à la fois dans le sens horaire, autrement dit en marche avant, et dans le sens anti-horaire, c'est-à-dire en marche arrière.In view of the foregoing, the object of the present invention is to provide a timepiece comprising a new type of correction mechanism of a display device, for example of the date, allowing the correction thereof at a time in clockwise, in other words in forward direction, and counter-clockwise, that is to say in reverse.

A cet effet, la présente invention a pour objet une pièce d'horlogerie comprenant un mécanisme correcteur bidirectionnel pour un dispositif d'affichage d'une grandeur temporelle tel qu'un quantième, le dispositif d'affichage étant actionné par une bascule de commande portant un râteau et commandée par une came sur laquelle la bascule de commande est en appui par un bras, l'appui de la bascule de commande sur la came et le retour en arrière dudit dispositif d'affichage étant assurés par une deuxième bascule dite bascule de rappel portant également un râteau, un organe de correction actionné par une tige de commande permettant d'écarter, via la bascule de rappel, le bras de la bascule de commande de la came sur laquelle il est normalement en appui.For this purpose, the subject of the present invention is a timepiece comprising a bidirectional corrective mechanism for a display device of a temporal magnitude such as a date, the display device being actuated by a control lever carrying a rake and controlled by a cam on which the control rocker is supported by an arm, the support of the control rocker on the cam and the return back of said display device being provided by a second rocker said rocker of reminder also carrying a rake, a correction member actuated by a control rod for removing, via the return lever, the arm of the control lever of the cam on which it is normally supported.

Grâce à ces caractéristiques, la présente invention procure une pièce d'horlogerie comprenant un mécanisme de correction qui permet de corriger en marche avant comme en marche arrière un dispositif d'affichage d'une grandeur temporelle tel qu'un dispositif d'affichage de quantième et ce malgré le fait que ce dispositif d'affichage soit actionné par une bascule elle-même commandée par une came. Ce résultat remarquable est atteint grâce au fait que le mécanisme correcteur selon l'invention comprend une seconde bascule commandée, via une tige de commande, par un organe de débrayage et qui permet d'écarter momentanément la bascule de commande du trajet de la came sur laquelle cette bascule de commande est normalement en appui. L'utilisateur peut alors effectuer une correction du mécanisme d'affichage en marche arrière car bien que la came tourne, le levier de commande ne se trouve pas sur sa trajectoire et ne vient pas taper contre celle-ci.Thanks to these features, the present invention provides a timepiece comprising a correction mechanism that corrects in forward and reverse a display device of a time magnitude such as a date display device despite the fact that this display device is actuated by a rocker itself controlled by a cam. This remarkable result is achieved thanks to the fact that the corrector mechanism according to the invention comprises a second lever controlled by a control rod, by a disengagement member and which makes it possible to temporarily shift the control lever from the path of the cam on which this control rocker is normally in support. The user can then make a correction of the display mechanism in reverse because although the cam rotates, the control lever is not in its path and does not knock against it.

Selon une caractéristique complémentaire de l'invention, l'organe de correction est formé par une came annulaire actionnée par la tige de commande et sur le profil de laquelle la bascule de rappel vient en appui par un bras.According to a complementary feature of the invention, the correction member is formed by an annular cam actuated by the control rod and on the profile of which the return lever is supported by an arm.

On a donc affaire à une pièce circulaire avantageusement centrée sur le centre du mouvement de la pièce d'horlogerie. De par sa forme géométrique et sa planéité, une telle pièce est relativement aisée à fabriquer et permet en outre de commander plusieurs dispositifs d'affichage d'une grandeur temporelle prévus en différents endroits de son périmètre.We are therefore dealing with a circular part advantageously centered on the center of movement of the timepiece. Due to its geometric shape and its flatness, such a part is relatively easy to manufacture and also makes it possible to control a plurality of display devices of a temporal size provided at different locations of its perimeter.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un exemple de réalisation du mécanisme de correction selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement en liaison avec le dessin annexé sur lequel:

Other features and advantages of the present invention will emerge more clearly from the following detailed description of an exemplary embodiment of the correction mechanism according to the invention, this example being given for purely illustrative and nonlimiting purposes only in connection with the attached drawing in which:

La présente invention procède de l'idée générale inventive qui consiste à procurer une pièce d'horlogerie comprenant un mécanisme de correction pour un dispositif d'affichage d'une grandeur temporelle tel qu'un dispositif de quantième qui permet de corriger ce dispositif dans les deux sens, autrement dit en marche avant comme en marche arrière. Pour atteindre cet objectif, la présente invention enseigne qu'il faut écarter la bascule de commande du dispositif d'affichage du chemin de la came en phase de correction arrière. A cet effet, il est prévu un mécanisme de débrayage qui, actionné par une tige de commande, permet d'écarter via une autre bascule appelée bascule de rappel le bras de la bascule de commande de la came sur laquelle il est normalement en appui.The present invention proceeds from the general inventive idea of providing a timepiece comprising a correction mechanism for a display device of a temporal magnitude such as a date device which makes it possible to correct this device in the two directions, in other words in forward and reverse direction. To achieve this objective, the present invention teaches that the control flip-flop of the cam path display device must be moved out of the rearward correction phase. For this purpose, there is provided a disengagement mechanism which, actuated by a control rod, allows to spread via another flip-flop called return lever the arm of the control lever of the cam on which it is normally supported.

La présente invention va être décrite en liaison avec un dispositif d'affichage de quantième. Néanmoins, comme il apparaîtra à la lecture de la présente description, l'invention ne se limite pas à un tel dispositif d'affichage de quantième et peut s'appliquer de manière analogue à un dispositif d'affichage du jour, à un dispositif d'affichage 24 heures et plus généralement à tout type de dispositif d'affichage d'une grandeur liée au temps.The present invention will be described in connection with a date display device. However, as will be apparent from the present description, the invention is not limited to such a date display device and can be applied in a similar manner to a day display device, to a device for displaying the date of day. 24-hour display and more generally to any type of display device of a magnitude related to time.

Un exemple de réalisation d'une pièce d'horlogerie comprenant le mécanisme de correction selon l'invention est représentée à la figure 1. Désignée dans son ensemble par la référence numérique générale 3, cette pièce d'horlogerie comprend en son centre un aiguillage de fuseau formé par une aiguille des heure 5a, une aiguille des minutes 5b et une aiguille des secondes 5c qui se déplacent au-dessus d'un cadran circulaire 7. Le mécanisme de fuseau a déjà été décrit dans la demande de brevet européen EP 1544691 au nom de la requérante et ne sera donc pas décrit davantage ici.An exemplary embodiment of a timepiece comprising the correction mechanism according to the invention is shown in FIG. figure 1 . Designated as a whole by the general reference numeral 3, this timepiece comprises in its center a spindle switch formed by a 5a hour hand, a minute hand 5b and a second hand 5c which move over a circular dial 7. The spindle mechanism has already been described in the patent application European EP 1544691 on behalf of the applicant and will not be described further here.

La montre 3 est complétée par:

  • un affichage rétrograde de quantième formé par une aiguille 9a qui se déplace devant une graduation 9b en arc de cercle qui s'étend entre le "1" et le "31";
  • un affichage rétrograde du jour formé par une aiguille 11 a qui se déplace le long d'une graduation 11 b repérée du "lundi" au "dimanche";
  • un affichage rétrograde 24 heures formé par une aiguille 13a qui se déplace le long d'une graduation 13b en arc de cercle qui s'étend entre "1" et "24".
Watch 3 is completed by:
  • a retrograde date display formed by a needle 9a which moves in front of a graduation 9b in an arc extending between the "1" and the "31";
  • a retrograde display of the day formed by a needle 11a which moves along a graduation 11b marked "Monday" to "Sunday";
  • a 24-hour retrograde display formed by a needle 13a which moves along a graduation 13b in an arc extending between "1" and "24".

L'affichage de la montre est complété par une indication de petite seconde 15.The display of the watch is completed by a small seconds indication 15.

La pièce d'horlogerie dont le mécanisme de correction est représenté en plan à la figure 2 est une montre à fuseau comprenant un affichage rétrograde 24 heures correspondant à l'heure locale du lieu où le porteur de la montre réside habituellement et un affichage 12 heures correspondant à l'heure du fuseau du lieu où le porteur de la montre séjourne temporairement. On verra ci-après que si le porteur de la montre souhaite corriger l'heure du fuseau, il faudra également corriger l'indication du quantième et l'indication du jour, et que si le porteur de la montre souhaite effectuer une mise à l'heure de la montre, il lui faudra également corriger l'affichage rétrograde 24 heures.The timepiece whose correction mechanism is shown in plan at figure 2 is a spindle watch comprising a 24-hour retrograde display corresponding to the local time of the place where the wearer of the watch usually resides and a 12-hour display corresponding to the time of the spindle of the place where the wearer of the watch is temporarily staying. It will be seen below that if the wearer of the watch wishes to correct the time of the time zone, it will also be necessary to correct the indication of the date and the indication of the day, and that if the wearer of the watch wishes to make a bet. time of the watch, it will also have to correct the retrograde display 24 hours.

Comme on le voit à la figure 2, le mécanisme de correction de la montre comprend notamment en son centre un renvoi 1 qui est solidaire d'une roue des heures 1a. Autrement dit, le renvoi 1 tourne dans le sens des aiguilles d'une montre et effectue un tour complet en douze heures. Ce renvoi 1 engrène avec une roue entraîneuse de quantième 2 qui tourne dans le sens anti-horaire à raison d'un tour en vingt-quatre heures. Cette roue entraîneuse de quantième 2 porte un doigt 4 par lequel elle entraîne à raison d'un pas par jour une roue de quantième 6 qui est indexée par un sautoir 8 et qui porte une came 10. En un endroit de son profil, la came présente un flanc abrupt 12 qui marque le passage entre le quantième du dernier jour d'un mois donné et le quantième du premier jour du mois suivant, autrement dit entre le quantième "31" et le quantième "1". Comme on le verra en détail ci-après, c'est la présence, sur le profil de la came 10, de ce flanc abrupt 12 qui, en temps normal, rend impossible la correction du quantième en marche arrière.As we see in figure 2 , the correction mechanism of the watch includes in particular at its center a reference 1 which is integral with a wheel hours 1a. In other words, the reference 1 rotates in a clockwise direction and performs a complete revolution in twelve hours. This reference 1 meshes with a date drive wheel 2 which rotates counterclockwise at the rate of one turn in twenty-four hours. This driving wheel of date 2 carries a finger 4 by which it drives at a rate of one step per day a date wheel 6 which is indexed by a jumper 8 and which carries a cam 10. At one point of its profile, the cam has an abrupt flank 12 which marks the passage between the date of the last day of a given month and the date of the first day of the following month, in other words between the date "31" and the date "1". As will be seen in detail below, it is the presence, on the profile of the cam 10, of this steep sidewall 12 which, in normal times, makes it impossible to correct the date in reverse.

Le mécanisme de correction selon l'invention est complété par une bascule de commande 14 pourvue à l'une de ses extrémités d'un bras 16 par lequel elle est en appui contre la came 10 en période de fonctionnement normal, et comprenant à son autre extrémité un râteau 18 par lequel elle engrène avec une roue d'affichage de quantième 20 qui porte l'indicateur de quantième 9a (non visible sur la figure 2). La bascule de commande 14 est pivotée en 22 tandis qu'une seconde bascule dite bascule de rappel 24 est pivotée en 26. Cette bascule de rappel 24 présente une structure similaire à celle de la bascule de commande 14 en comprenant notamment un râteau 28 par lequel elle engrène avec la roue d'affichage de quantième 20. Comme on peut le voir à l'examen de la figure 2, la bascule de rappel 24 est contrainte par un élément ressort 30 qui tend à la faire tourner dans le sens horaire. A son tour, la bascule de rappel 24 tend donc à faire tourner la roue d'affichage de quantième 20 dans le sens anti-horaire, ce qui tend à faire tourner la bascule de commande 14 dans le sens horaire et à maintenir son bras 16 en appui contre le profil de la came 10.The correction mechanism according to the invention is completed by a control rocker 14 provided at one of its ends with an arm 16 by which it bears against the cam 10 during normal operation, and comprising at its other end a rake 18 by which it meshes with a date display wheel 20 which carries the date indicator 9a (not visible on the figure 2 ). The control lever 14 is pivoted at 22 while a second rocker said return lever 24 is pivoted at 26. This return lever 24 has a similar structure to that of the control lever 14 including in particular a rake 28 by which it meshes with the date display wheel 20. As can be seen in the examination of the figure 2 , the return lever 24 is constrained by a spring element 30 which tends to rotate it clockwise. In turn, the return lever 24 tends to rotate the date display wheel 20 in the counterclockwise direction, which tends to turn the control lever 14 clockwise and to maintain its arm 16 resting against the profile of the cam 10.

Comme on peut le voir à l'examen du dessin, dans l'exemple représenté l'élément ressort 30 vient de matière avec la bascule de rappel 24 et est en appui contre une butée 32 pour son préarmage. Pour atteindre ce résultat, on peut réaliser cette bascule par exemple par une technique de photogravure LIGA. Il va néanmoins de soi que l'élément ressort 30 pourrait être réalisé sous la forme d'une pièce séparée de la bascule de rappel 24.As can be seen from the drawing, in the example shown the spring element 30 comes from material with the return lever 24 and bears against a stop 32 for its pre-arming. To achieve this result, one can achieve this latch for example by a photoengraving technique LIGA. However, it goes without saying that the spring element 30 could be made in the form of a separate part of the return lever 24.

A son extrémité opposée à celle qui porte le râteau 28, la bascule de rappel 24 présente un palpeur 34 qui coopère avec un organe de débrayage désigné dans son ensemble par la référence numérique générale 36. Dans l'exemple représenté au dessin, cet organe de débrayage 36 se présente sous la forme d'une came annulaire 38 centrée sur le centre du mouvement et sur le profil intérieur de laquelle le palpeur 34 de la bascule de rappel 24 vient en appui. En observant attentivement la figure 2, on remarque que dans la situation dans laquelle le mécanisme de correction selon l'invention est représenté sur cette figure, le palpeur 34 de la bascule de rappel 24 est situé au niveau d'un décrochement 40 que présente la came annulaire 38 sur son profil intérieur. La raison de la présence de ce décrochement 40 sera bien comprise à la lecture de ce qui suit. On peut également d'ores et déjà noter que la came annulaire 38 présente deux autres décrochements similaires pour la commande de deux autres dispositifs d'affichage d'une grandeur temporelle comme il sera expliqué en détail ultérieurement.At its end opposite to that carrying the rake 28, the return lever 24 has a feeler 34 which cooperates with a disengagement member generally designated by the general numerical reference 36. In the example shown in the drawing, this member of FIG. disengagement 36 is in the form of an annular cam 38 centered on the center of the movement and on the inner profile of which the probe 34 of the return lever 24 bears. By carefully observing the figure 2 , it is noted that in the situation in which the correction mechanism according to the invention is shown in this figure, the feeler 34 of the return lever 24 is located at a recess 40 that presents the annular cam 38 on its profile inside. The reason for the presence of this setback 40 will be well understood on reading the following. It can also already be noted that the annular cam 38 has two other similar recesses for the control of two other display devices of a time magnitude as will be explained in detail later.

On voit sur la figure 2 que le bras 16 de la bascule de commande 14 est au fond du flanc abrupt 12 que présente la came 10 sur son profil. Ceci signifie que le mécanisme indicateur de quantième auquel appartient notamment la roue de quantième 6 et sa came associée 10 vient de passer du dernier quantième "31" d'un mois donné au premier quantième "1" du mois suivant. Supposons maintenant que, partant de cette situation, il faille corriger l'indication du quantième. Si au cours de cette correction, la roue de quantième 6 tourne dans le sens des aiguilles d'une montre, on n'observe aucun problème particulier: le bras 16 de la bascule de commande 14 va suivre le profil de la came 10 et entraîner par son râteau 18 la roue d'affichage de quantième 20, ce qui aura pour effet d'incrémenter pas à pas l'indication du quantième. Il en va par contre tout à fait autrement si l'opération de correction de l'indication du quantième provoque une rotation en sens contraire de la roue de quantième 6 et donc de la came 10. En effet, dans ce cas, le bras 16 de la bascule de commande 14 va taper et s'arc-bouter contre le flanc abrupt 12 du profil de ladite came 10 et le mécanisme va se retrouver bloqué. C'est la raison pour laquelle il faut faire en sorte que, lors d'une correction de l'indication du quantième en marche arrière, le bras 16 de la bascule de commande 14 se trouve écarté du trajet de la came 10. La came annulaire 38, associée à une tige de commande 42, est prévue pour remédier à ce problème.We see on the figure 2 that the arm 16 of the control lever 14 is at the bottom of the steep side 12 that has the cam 10 on its profile. This means that the date indicator mechanism which belongs in particular to the date wheel 6 and its associated cam 10 has just passed the last calendar "31" of a given month to the first calendar "1" of the following month. Suppose now that, starting from this situation, it is necessary to correct the indication of the date. If during this correction, the date wheel 6 rotates in the clockwise direction, no particular problem is observed: the arm 16 of the control lever 14 will follow the profile of the cam 10 and cause by its rake 18 the date display wheel 20, which will have the effect of incrementing step by step the indication of the date. However, it is quite different if the operation of correcting the indication of the date causes a rotation in the opposite direction of the date wheel 6 and therefore of the cam 10. In fact, in this case, the arm 16 control flip-flop 14 will tap and bend against the steep side 12 of the profile of said cam 10 and the mechanism will become blocked. This is the reason why it must be ensured that, during a correction of the indication of the date in reverse, the arm 16 of the control lever 14 is removed from the path of the cam 10. The annular cam 38, associated with a control rod 42, is provided to remedy this problem.

En effet, comme on peut le voir à la figure 3A et mieux encore sur la figure 3B, la tige de commande 42 est reliée cinématiquement à la came annulaire 38 via un élément 44 qui permet de transformer un déplacement linéaire de ladite tige de commande 42 en un mouvement de pivotement de ladite came annulaire 38. A cet effet, l'élément 44 de transformation de mouvement comprend trois tenons rivetés respectivement 46, 48 et 50. La premier 46 de ces trois tenons forme l'axe de pivotement de l'élément de transformation 44. Par son second tenon 48, l'élément de transformation 44 est en liaison avec la tige de commande 42. A cet effet, le tenon 48 fait saillie dans une gorge annulaire 52 prévue en un endroit de la longueur de la tige de commande 42. Enfin, l'élément de transformation de mouvement 44 est couplé cinématiquement avec la came annulaire 38 via le troisième tenon 50 qui est libre de se déplacer dans un trou oblong 54 ménagé dans ladite came annulaire 38.Indeed, as can be seen at figure 3A and even better on the figure 3B , the control rod 42 is kinematically connected to the annular cam 38 via an element 44 which makes it possible to convert a linear displacement of said control rod 42 into a pivoting movement of said annular cam 38. For this purpose, the element 44 the first 46 of these three tenons forms the pivot axis of the transformation element 44. By its second tenon 48, the transformation element 44 is in the form of a rivet 46, 48 and 50 respectively. connection with the control rod 42. For this purpose, the pin 48 projects into an annular groove 52 provided at a location along the length of the control rod 42. Finally, the motion transformation element 44 is kinematically coupled with the annular cam 38 via the third pin 50 which is free to move in an oblong hole 54 formed in said annular cam 38.

On a déjà dit plus haut que le mécanisme de correction selon la présente invention est destiné à une pièce d'horlogerie du type montre à fuseau horaire, étant entendu que cet exemple est donné à titre purement illustratif, la présente invention pouvant s'appliquer à la correction de tout type de dispositif d'affichage d'une grandeur temporelle. Ainsi, dans le cas d'une telle montre à fuseau, la tige de commande 42 présente trois positions stables, à savoir une position neutre dans laquelle elle permet le remontage du mouvement, une première position tirée qui permet la correction de l'indicateur de fuseau horaire 12 heures (il s'agit d'un indicateur sautant qui avance ou recule par pas d'une heure sans que l'affichage des minutes en soit affecté) et une seconde position tirée qui permet la mise à l'heure de la montre. Ces trois positions de la tige de commande 42 sont classiquement indexées par une tirette 56 du mouvement de base qui fait le lien entre un sautoir de tirette 60 et ladite tige de commande 42.It has already been said above that the correction mechanism according to the present invention is intended for a timepiece of the time zone watch type, it being understood that this example is given purely by way of illustration, the present invention being applicable to the correction of any type of display device of a temporal magnitude. Thus, in the case of such a spindle watch, the control rod 42 has three stable positions, namely a neutral position in which it allows the reassembly of the movement, a first drawn position which allows the correction of the indicator of 12-hour time zone (this is a jumping indicator that moves forward or backward in one-hour increments without the minute display being affected) and a second drawn position that allows the time to be set. shows. These three positions of the control rod 42 are conventionally indexed by a pull tab 56 of the base movement which is the link between a puller puller 60 and said control rod 42.

Supposons donc maintenant que l'on exerce une traction sur la tige de commande 42 pour la faire passer de sa position neutre de remontage à sa première position tirée. Dans ce cas, la tige de commande 42 entraîne avec elle le tenon 48, ce qui provoque le pivotement de l'élément de transformation de mouvement 44 autour de son axe de pivotement matérialisé par le tenon 46. A son tour, le tenon 50, solidaire de l'élément de transformation 44, coulisse dans le trou oblong 54 et provoque le pivotement de la came annulaire 38 dans le sens anti-horaire. On se retrouve alors dans la position représentée sur la figure 3C où la came annulaire 38 a tourné dans le sens contraire des aiguilles d'une montre.Suppose now that we pull on the control rod 42 to move it from its neutral position winding to its first pulled position. In this case, the control rod 42 carries with it the tenon 48, which causes the pivoting of the movement transformation element 44 around its pivot axis materialized by the pin 46. In turn, the pin 50, integral with the transformation element 44, slides in the oblong hole 54 and causes the pivoting of the annular cam 38 in the anti-clockwise direction. We are then in the position represented on the figure 3C where the annular cam 38 has rotated counterclockwise.

Le pivotement dans le sens anti-horaire de la came annulaire 38 permet d'écarter le bras 16 de la bascule de commande 14 de la trajectoire de la came 10 comme illustré à la figure 4. En effet, sous l'effet du pivotement de ladite came annulaire 38, le palpeur 34 de la bascule de rappel 24 remonte le long du flanc 58 du décrochement 40 et glisse sur le périmètre intérieur de la came annulaire 38. Ce faisant, la bascule de rappel 24 pivote dans le sens contraire des aiguilles d'une montre et provoque, via la roue d'affichage de quantième 20, le pivotement de la bascule de commande 14 également dans le sens anti-horaire, ce qui a pour effet d'écarter le bras 16 de cette bascule de commande 14 du trajet de la came 10. On comprendra qu'au cours de ce mouvement, l'indicateur de quantième 9a (non visible sur la figure 2), entraîné par la roue d'affichage de quantième 20, va se déplacer et aller en fond de l'échelle de quantième, c'est-à-dire légèrement au-delà du quantième "31 ".The anti-clockwise pivoting of the annular cam 38 makes it possible to move the arm 16 of the control lever 14 away from the trajectory of the cam 10 as illustrated in FIG. figure 4 . Indeed, under the effect of the pivoting of said annular cam 38, the probe 34 of the return lever 24 rises along the side 58 of the recess 40 and slides on the inner perimeter of the annular cam 38. In doing so, the rocker 24 rotates counterclockwise and causes, via the date display wheel 20, the pivoting of the control lever 14 also in the counterclockwise direction, which has the effect of move the arm 16 of this control lever 14 away from the path of the cam 10. It will be understood that during this movement, the date indicator 9a (not visible on the figure 2 ), driven by the date display wheel 20, will move and go to the bottom of the date scale, that is to say slightly beyond the date "31".

Intéressons-nous maintenant aux raisons pour lesquelles il est nécessaire d'écarter le bras 16 de la bascule de commande 14 du trajet de la came 10. En supposant que la tige de commande 42 est amenée dans sa première position tirée, cela signifie que l'on souhaite corriger l'indication de l'heure de fuseau horaire. On va donc faire tourner la tige de commande 42 en marche avant ou en marche arrière selon que l'on veut incrémenter ou décrémenter l'indication de l'heure de fuseau horaire par pas d'une heure. Or, quand on fait tourner la tige de commande 42, on fait tourner la roue des heures (non représentée) et donc aussi le renvoi 1. Si le renvoi 1 tourne dans le sens horaire, autrement dit le sens dans lequel il tourne en régime de fonctionnement normal, la came 10 tourne dans le sens horaire et le bras 16 de la bascule de commande 14 glisse sans problème le long du profil de ladite came 10. Par contre, si en phase de correction de l'indication de fuseau dans le sens anti-horaire, le renvoi 1 tourne dans le sens anti-horaire, la came 10 va tourner dans le sens horaire et le bras 16 de la bascule de commande 14 va venir taper contre le flanc abrupt 12 de ladite came 10 et se bloquer. C'est la raison pour laquelle il faut, dans ce cas, que le bras 16 de la bascule de commande 14 soit écarté du trajet de la came 10.Let us now consider the reasons why it is necessary to move the arm 16 of the control lever 14 away from the path of the cam 10. Assuming that the control rod 42 is brought into its first drawn position, this means that the it is desired to correct the indication of the time zone time. So we will turn the control rod 42 forward or reverse depending on whether we want to increment or decrement the indication of the time zone time in steps of one hour. However, when the control rod 42 is rotated, the hour wheel (not shown) is rotated and therefore also the reference 1. If the transmission 1 rotates in the clockwise direction, in other words the direction in which it is running. in normal operation, the cam 10 rotates clockwise and the arm 16 of the control lever 14 slides smoothly along the profile of said cam 10. On the other hand, if during the correction phase of the indication of spindle in the anti-clockwise, the return 1 rotates counterclockwise, the cam 10 will rotate clockwise and the arm 16 of the control lever 14 will come to tap against the steep side 12 of said cam 10 and lock . This is why it is necessary, in this case, that the arm 16 of the control lever 14 is spaced from the path of the cam 10.

Comme il a déjà été mentionné en préambule, la présente invention ne se limite pas à un mécanisme de correction pour un dispositif d'affichage d'un quantième. En effet, la présente invention s'applique de manière très générale à tout type d'affichage d'une grandeur temporelle tel qu'entre autres un dispositif d'affichage des jours ou un dispositif d'affichage 24 heures comme il ressort des figures 2 et 4 annexées à la présente demande de brevet. On constate en effet à l'examen de ces figures qu'en plus du dispositif d'affichage de quantième, la Requérante à prévu d'équiper son mouvement d'un dispositif d'affichage des jours qui, pour l'essentiel, présente la même structure que le dispositif d'affichage de quantième. Plus précisément, ce mécanisme d'affichage des jours comprend une roue entraîneuse de jours 2a qui tourne dans le sens anti-horaire en étant entraînée par le renvoi 1. Cette roue entraîneuse de jours 2a porte un doigt 4a par lequel elle entraîne à raison d'un pas par jour une roue des jours 6a qui comporte quatorze dents et qui effectue donc un tour complet en quatorze jours. A cet effet, la roue des jours 6a porte une came 10a qui présente un profil de came double avec deux flancs abrupts 12a1 et 12a2 qui sont symétriques par rapport au centre géométrique de ladite came 10a. Il va de soi qu'un tel profil de came n'est qu'une question de choix de la part du constructeur et que l'on aurait très bien pu envisager une came avec un profil simple effectuant un tour complet en sept jours à l'image de la came 10 portée par la roue de quantième 6. Chacun des deux flancs abrupts 12a1 et 12a2 de la came 10a marque le passage de l'indicateur des jours du dernier jour d'une semaine au premier jour de la semaine suivante, à savoir du dimanche au lundi. On notera que la roue des jours 6a est indexée par un sautoir 8a.As already mentioned in the preamble, the present invention is not limited to a correction mechanism for a date display device. Indeed, the present invention applies very generally to any type of display of a time value such as inter alia a day display device or a 24-hour display device as is apparent from the figures 2 and 4 annexed to this patent application. It can be seen from these figures that in addition to the date display device, the Applicant has planned to equip its movement with a display device days which, for the most part, has the same structure as the date display device. More specifically, this day display mechanism comprises a driving wheel of days 2a which rotates in the counterclockwise direction being driven by the return 1. This driving wheel of days 2a carries a finger 4a by which it drives at a rate of one step per day a wheel of days 6a which has fourteen teeth and thus performs a complete revolution in fourteen days. For this purpose, the day wheel 6a carries a cam 10a which has a double cam profile with two steep sides 12a 1 and 12a 2 which are symmetrical with respect to the geometric center of said cam 10a. It goes without saying that such a cam profile is only a matter of choice on the part of the manufacturer and that we could very well have envisaged a cam with a simple profile performing a complete revolution in seven days. image of the cam 10 carried by the date wheel 6. Each of the two steep sides 12a 1 and 12a 2 of the cam 10a marks the passage of the indicator of the days of the last day of a week to the first day of the week next, from Sunday to Monday. It will be noted that the wheel of the days 6a is indexed by a jumper 8a.

Le mécanisme de correction du dispositif d'affichage des jours est complété par une bascule de commande 14a qui par son bras 16a est en appui contre le profil de la came 10a et qui engrène par son râteau 18a avec une roue d'affichage des jours 20a. Il est également prévu une bascule de rappel 24a contrainte par un ressort 30a et qui, à l'une de ses extrémités, comprend un râteau 28a par lequel elle engrène avec la roue d'affichage des jours 20a tandis qu'à son autre extrémité, elle comprend un palpeur 34a qui est situé dans un décrochement 40a que présente la came annulaire 38 sur son profil intérieur.The correction mechanism of the day display device is completed by a control lever 14a which by its arm 16a bears against the profile of the cam 10a and which meshes with its rake 18a with a display wheel 20a. . There is also provided a biasing latch 24a constrained by a spring 30a and which, at one of its ends, comprises a rake 28a by which it meshes with the display wheel 20a days while at its other end, it comprises a feeler 34a which is located in a recess 40a that has the annular cam 38 on its inner profile.

On rappelle que l'on s'intéresse ici à une montre à fuseau horaire. Par conséquent, dans la première position tirée de la tige de commande 42, lorsqu'on souhaite corriger l'heure de fuseau en laissant l'heure locale inchangée, il va falloir corriger simultanément l'indication du quantième et l'indication du jour. La correction de l'indication du quantième a déjà été décrite en détail ci-dessus. La correction de l'indication du jour se fait de manière identique. En effet, lorsqu'on tourne la tige de commande 42 et que cela provoque le pivotement de la came annulaire 38 dans le sens inverse des aiguilles d'une montre, le palpeur 34a de la bascule de rappel 24a remonte le long du flanc 58a du décrochement 40a et glisse sur le périmètre intérieur de la came annulaire 38. Sous l'effet du déplacement de son palpeur 34a, la bascule de rappel 24a pivote dans le sens anti-horaire et provoque, via la roue d'affichage des jours 20a, le pivotement de la bascule de commande 14a également dans le sens anti-horaire. Ceci à pour effet d'écarter le bras 16a de cette bascule de commande 14a du trajet de la came 10a. On comprendra qu'au cours de ce mouvement, l'indicateur de jours 11a (non visible sur la figure 2), entraîné par la roue d'affichage des jours 20a, va se déplacer et aller en fond de l'échelle des jours, légèrement au-delà de l'indication du dimanche.We recall that we are interested here in a time zone watch. Therefore, in the first position drawn from the control rod 42, when it is desired to correct the time zone by leaving the local time unchanged, it will be necessary to simultaneously correct the indication of the date and the indication of the day. The correction of the indication of the date has already been described in detail above. The correction of the indication of the day is done in the same way. Indeed, when turning the control rod 42 and that it causes the pivoting of the annular cam 38 in the counterclockwise direction, the feeler 34a of the return lever 24a rises along the side 58a of the recess 40a and slides on the inner perimeter of the annular cam 38. Under the effect of the displacement of its probe 34a, the return lever 24a pivots in the counterclockwise direction and causes, via the display wheel 20a days, pivoting of the control rocker 14a also in the counter-clockwise direction. This has the effect of spreading the arm 16a of this control rocker 14a of the path of the cam 10a. It will be understood that during this movement, the indicator of days 11a (not visible on the figure 2 ), driven by the display wheel of days 20a, will move and go to the bottom of the day scale, slightly beyond the Sunday indication.

On constate donc que par une action unique sur la tige de commande, on peut corriger simultanément l'heure de fuseau aussi bien dans le sens horaire que anti-horaire, l'indication du quantième et l'indication du jour ceci en prévoyant uniquement en regard des palpeurs 34, 34a des bascules de rappel 24, 24a deux décrochements 40, 40a sur le profil intérieur de la came annulaire 38. Le dispositif de correction selon la présente invention se caractérise donc par une simplicité des moyens mis en oeuvre et par une grande facilité d'utilisation.It can therefore be seen that, by a single action on the control rod, it is possible to simultaneously correct the time of spindle both in the clockwise and counterclockwise direction, the indication of the date and the indication of the day, this only providing for the probes 34, 34a of the return latches 24, 24a have two recesses 40, 40a on the inner profile of the annular cam 38. The correction device according to the present invention is therefore characterized by a simplicity of the means used and by a great ease of use.

Quand on fait passer la tige de commande 42 de sa première à sa seconde position tirée pour pouvoir effectuer la mise à l'heure de la montre, cela provoque un pivotement supplémentaire de la came annulaire 38. Ce pivotement supplémentaire est cependant sans effet sur les bascules de rappel 24, 24a dans la mesure où leurs palpeurs respectifs 34, 34a ont gravi les flancs 58, 58a des décrochements 40, 40a et glissent sur le périmètre intérieur de la came annulaire 38. Les bras 16, 16a des bascules de commande 14, 14a restent donc toujours en dehors du trajet des cames 10, 10a.When the control rod 42 is moved from its first position to its second pulled position in order to be able to set the time of the watch, this causes an additional pivoting of the annular cam 38. This additional pivoting however has no effect on the return flip-flops 24, 24a insofar as their respective feelers 34, 34a have climbed the flanks 58, 58a of the recesses 40, 40a and slide on the inside perimeter of the annular cam 38. The arms 16, 16a of the control flip-flops 14 , 14a therefore remain always outside the path of the cams 10, 10a.

On a déjà précisé ci-dessus que la montre comprenait également un affichage 24 heures de l'heure locale. Par conséquent, lorsqu'on corrige la position des aiguilles des heures et des minutes, il faut également pouvoir corriger l'indication 24 heures. A cet effet, le dispositif d'affichage 24 heures comprend un renvoi 60 entraîné par le mouvement de la montre et qui engrène avec une roue 24 heures 6b qui porte une came 10b. En un endroit de son profil, cette came 10b présente un flanc abrupt 12b qui marque le passage entre la vingt-quatrième heure d'une journée et la première heure de la journée suivante. Une bascule de commande 14b est en appui par son bras 16b contre le profil de la came 10b et engrène avec une roue d'affichage 24 heures 20b via son râteau 18b. De même, une bascule de rappel 24b contrainte par un élément ressort 30b engrène par son râteau 28b avec la roue d'affichage 24 heures 20b. Cette bascule de rappel 24b comprend également un palpeur 34b, qui, en position de fonctionnement normal de la montre (voir figure 2), se trouve à l'intérieur d'un décrochement 40b. Lorsque la tige de commande 42 est amenée dans sa première position tirée dans laquelle il est possible de corriger l'heure du fuseau, la came annulaire 38 pivote et le palpeur 34b remonte le long du flanc 58b du décrochement 40b et glisse sur le périmètre intérieur de ladite came annulaire 38. Sous l'effet du déplacement de son palpeur 34b, la bascule de rappel 24b pivote dans le sens contraire des aiguilles d'une montre et provoque, via la roue d'affichage 24 heures 20, le pivotement de la bascule de commande 14b également dans le sens anti-horaire. Ceci a pour effet d'écarter le bras 16b de cette bascule de commande 14b du trajet de la came 10b.It has already been stated above that the watch also includes a 24 hour local time display. Therefore, when correcting the position of the hour and minute hands, you must also be able to correct the 24 hour indication. For this purpose, the 24-hour display device comprises a transmission 60 driven by the movement of the watch and which meshes with a 24 hour wheel 6b which carries a cam 10b. In one place of its profile, this cam 10b has an abrupt flank 12b which marks the passage between the twenty-fourth hour of a day and the first hour of the following day. A control rocker 14b is supported by its arm 16b against the profile of the cam 10b and meshes with a display wheel 24 hours 20b via its rake 18b. Similarly, a return latch 24b constrained by a spring member 30b meshes with its rake 28b with the display wheel 24 hours 20b. This return lever 24b also comprises a feeler 34b, which, in the normal operating position of the watch (see FIG. figure 2 ), lies inside a recess 40b. When the control rod 42 is brought into its first drawn position in which it is possible to correct the time of the spindle, the annular cam 38 pivots and the probe 34b rises along the side 58b of the recess 40b and slides on the inner perimeter of said annular cam 38. Under the effect of the displacement of its probe 34b, the return lever 24b pivots in counterclockwise and causes, via the display wheel 24 hours 20, the pivoting of the control rocker 14b also in the counterclockwise direction. This has the effect of spreading the arm 16b of the control rocker 14b of the path of the cam 10b.

Néanmoins, dans la première position tirée de la tige de commande 42, le fait de faire tourner cette tige 42 dans un sens ou dans l'autre pour corriger l'heure de fuseau est sans effet sur l'affichage 24 heures. En effet, dans sa première position tirée, la tige de commande 42 attaque un train d'engrenages qui n'est pas relié au dispositif d'affichage 24 heures. Par contre, dans sa seconde position tirée correspondant à la mise à l'heure de la montre, la tige de commande attaque un autre train d'engrenages qui lui est relié au dispositif d'affichage 24 heures. Par conséquent, dans la seconde position tirée de la tige de commande 42, on peut corriger sans problème le dispositif d'affichage 24 heures dans la mesure où le bras 16b de la bascule de commande 14b est déjà écarté du trajet de la came 10b lorsque ladite tige de commande 42 est amenée dans sa première position tirée.Nevertheless, in the first position drawn from the control rod 42, rotating this rod 42 in one direction or the other to correct the spindle time has no effect on the 24-hour display. Indeed, in its first drawn position, the control rod 42 drives a gear train which is not connected to the display device 24 hours. In contrast, in its second drawn position corresponding to the time setting of the watch, the control rod drives another gear train which is connected to the display device 24 hours. Consequently, in the second position drawn from the control rod 42, the 24-hour display device can be corrected without any problem insofar as the arm 16b of the control lever 14b is already spaced from the path of the cam 10b when said control rod 42 is brought into its first pulled position.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. En particulier, on comprendra que lorsque la tige de commande est ramenée dans sa position neutre de remontage, la came annulaire revient dans sa position d'origine et les palpeurs retombent dans leurs décrochements respectifs. Sous l'effet du déplacement du palpeur, la bascule de rappel fait pivoter la roue d'affichage et la bascule de commande revient en appui contre sa came. Pendant la phase de correction, la came aura tourné et la bascule de commande viendra en appui contre celle-ci en un endroit différent de l'endroit où elle était en appui avant la correction, de sorte que la correction effectuée sera prise en compte par le dispositif d'affichage.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, it will be understood that when the control rod is returned to its neutral position of reassembly, the annular cam returns to its original position and feelers fall back into their respective recesses. Under the effect of the movement of the probe, the return rocker rotates the display wheel and the control rocker rests against its cam. During the correction phase, the cam will have turned and the control lever will come to bear against it in a different place from where it was in support before the correction, so that the correction made will be taken into account by the display device.
