Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie mécanique. Elle concerne, plus particulièrement, un système de commande de chronographe doté d'une pièce de commande comprenant :

  • une portion d'entraînement agencée pour recevoir une action de commande, et
  • une zone de positionnement agencée pour coopérer avec un organe de positionnement de manière à définir des positions stables de la pièce de commande.
The present invention relates to the field of mechanical watchmaking. It relates more particularly to a chronograph control system with a control part comprising:
  • a drive portion arranged to receive a control action, and
  • a positioning zone arranged to cooperate with a positioning member so as to define stable positions of the control part.

Etat de la techniqueState of the art

Dans le domaine des chronographes, il est connu notamment du document WO2009/098307 de commander les fonctions START, STOP et RESET au moyen de navettes qui, selon leurs positions, permettent d'embrayer ou de débrayer une roue de chronographe, d'actionner ou non un frein, d'actionner ou de relever des marteaux de remise à zéro. Dans ce document, les différentes fonctions sont réalisées au moyen d'une couronne mobile en rotation. La couronne est ainsi entraînée, à partir d'une position initiale, dans une première direction pour réaliser le START. Puis, on revient la position initiale pour réaliser le STOP et on entraîne la couronne dans une deuxième direction pour réaliser le RESET.In the field of chronographs, it is known from the document WO2009 / 098307 to control the START, STOP and RESET functions by means of shuttles which, according to their positions, make it possible to engage or disengage a chronograph wheel, to actuate or not to apply a brake, to actuate or to lift hammers for zero. In this document, the various functions are carried out by means of a rotating ring. The crown is thus driven, from an initial position, in a first direction to perform the START. Then, we return the initial position to perform the STOP and drive the crown in a second direction to achieve the RESET.

Il est donc nécessaire, pour redémarrer une mesure, de passer à nouveau par la position initiale, correspondant à la fonction STOP. Un retour manuel à cette position peut ne pas être pratique. Par exemple, si une deuxième mesure doit être déclenchée rapidement après une première, il faut d'abord passer de la position RESET à la position STOP. Un retour automatique pose également des problèmes au niveau du fonctionnement pour ramener la couronne et, dans l'exemple du mécanisme décrit dans le document précité, pour relever les marteaux.It is therefore necessary, to restart a measurement, to go back to the initial position corresponding to the STOP function. A manual return to this position may not be practical. For example, if a second measurement is to be triggered quickly after a first, you must first go from the RESET position to the STOP position. Automatic return also poses operating problems to bring back the crown and, in the example of the mechanism described in the aforementioned document, to raise the hammers.

La présente invention a pour but de résoudre les inconvénients susmentionnés.The present invention aims to solve the aforementioned drawbacks.

  • les figures 1 à 4 illustrent différentes position d'une pièce de commande selon l'invention, et
  • les figures 5 à 8 représentent ces différentes positions dans le cadre d'un système de commande, particulièrement adapté pour un mécanisme de chronographe
Other details of the invention will emerge more clearly on reading the description which follows, made with reference to the appended drawings, in which:
  • the Figures 1 to 4 illustrate different positions of a control part according to the invention, and
  • the Figures 5 to 8 represent these different positions as part of a control system, particularly suitable for a chronograph mechanism

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

Les figures 1 à 4 ne représentent que les pièces principales d'un mode de réalisation d'un système de commande d'un chronographe selon l'invention. Ce système comporte une pièce de commande 10 qui comprend une portion d'entraînement 12 agencée pour recevoir une action de commande. Selon l'exemple proposé, cette portion d'entraînement 12 est disposée à la périphérie d'une bascule 14 destinée à être montée pivotante sur un bâti. Cette portion d'entraînement 12 est typiquement une denture susceptible d'être actionnée par une couronne de commande, telle que proposée dans le document WO2009/098307 , pour commander un mécanisme de chronographe. La portion d'entraînement 12 pourrait également être prévue pour être actionnée par un ou plusieurs poussoirs.The Figures 1 to 4 represent only the main parts of an embodiment of a control system of a chronograph according to the invention. This system comprises a control part 10 which comprises a drive portion 12 arranged to receive a control action. According to the proposed example, this drive portion 12 is disposed at the periphery of a rocker 14 intended to be pivotally mounted on a frame. This drive portion 12 is typically a toothing that can be actuated by a control ring, as proposed in the document WO2009 / 098307 , to control a chronograph mechanism. The drive portion 12 could also be provided to be actuated by one or more pushers.

La pièce de commande 10 comprend également une zone de positionnement 16 agencée pour coopérer avec un organe de positionnement 18 de manière à définir des positions stables de la pièce de commande 10. L'organe de positionnement 18 est, typiquement, un ressort sautoir dont l'extrémité biseautée est agencée pour coopérer avec la zone de positionnement 16. On retrouve une telle zone de positionnement 16 dans les systèmes de came de l'état de la technique.The control part 10 also comprises a positioning zone 16 arranged to cooperate with a positioning member 18 so as to define stable positions of the control member 10. The positioning member 18 is, typically, a jumper spring of which the The beveled end is arranged to cooperate with the positioning zone 16. Such a positioning zone 16 is found in the cam systems of the state of the art.

Selon l'invention, la pièce de commande 10 comprend un levier mobile 20 dont une extrémité libre participe à la zone de positionnement 16. Dans le mode de réalisation proposé, le levier mobile 20 est disposé sur la bascule 14 de manière à pivoter en référence à elle. Le levier mobile 20 est disposé dans une échancrure 22 de la bascule 14, dont les bords 22a, 22b forment des butées définissant une première et une deuxième positions du levier mobile 20. La première position est représentée sur la figure 2 et correspond à une mise en butée du levier mobile 20 sur le bord 22a de l'échancrure 22. La deuxième position est représentée sur les figures 1, 3 et 4 et correspond à une mise en butée du levier mobile 20 sur le bord 22b de l'échancrure 22.According to the invention, the control part 10 comprises a movable lever 20 whose free end participates in the positioning zone 16. In the proposed embodiment, the mobile lever 20 is disposed on the rocker 14 so as to pivot with reference to her. The mobile lever 20 is disposed in a notch 22 of the rocker 14, the edges 22a, 22b form stops defining a first and a second position of the movable lever 20. The first position is shown on the figure 2 and corresponds to an abutment of the movable lever 20 on the edge 22a of the notch 22. The second position is represented on the figures 1 , 3 and 4 and corresponds to an abutment of the mobile lever 20 on the edge 22b of the notch 22.

Le levier mobile 20 est disposé dans le plan général défini par la bascule 14 et reste dans ce plan pendant ses déplacements. Typiquement, le levier mobile 20 est situé dans l'épaisseur de la bascule 14.The mobile lever 20 is disposed in the general plane defined by the latch 14 and remains in this plane during its movements. Typically, the mobile lever 20 is located in the thickness of the rocker 14.

La bascule 14 comprend, à sa périphérie, une première encoche 24 conformée pour coopérer avec l'organe de positionnement 18. La première encoche 24 définit encore un rebord 26 dont le rôle apparaîtra plus loin.The rocker 14 comprises, at its periphery, a first notch 24 shaped to cooperate with the positioning member 18. The first notch 24 further defines a flange 26 whose role will appear later.

Le levier mobile 20 comprend, à son extrémité libre, une deuxième encoche 28 également conformée pour coopérer avec l'organe de positionnement 18. La deuxième encoche 28 définit également un bec 30 dont le rôle apparaîtra plus loin. Lorsque le levier mobile 20 est dans sa deuxième position, représentée sur les figures 1, 3 et 4, on peut voir sur ces figures qu'une troisième encoche 32 est définie entre la première et la deuxième encoches 28. Cette troisième encoche 32 est plus précisément définie, d'une part, par le rebord 26 de la première encoche 24 et, d'autre part, par le bec 30 de la deuxième encoche 28.The mobile lever 20 comprises, at its free end, a second notch 28 also shaped to cooperate with the positioning member 18. The second notch 28 also defines a spout 30 whose role will appear later. When the mobile lever 20 is in its second position, shown on the figures 1 , 3 and 4 , it can be seen in these figures that a third notch 32 is defined between the first and the second notches 28. This third notch 32 is more precisely defined, on the one hand, by the flange 26 of the first notch 24 and, d on the other hand, by the spout 30 of the second notch 28.

De manière particulièrement intéressante, on constate que le bec 30 est dimensionné de manière à ce que le rebord 26 puisse se loger sous le bec 30 et que ce dernier puisse recouvrir le rebord 26. Lorsque le levier mobile 20 est dans sa première position représentée sur la figure 2, le rebord 26 n'est plus exposé à l'organe de positionnement 18. Ainsi, dans cette première position du levier mobile 20, la zone de positionnement 16 définit deux positions de la pièce de commande 10, par coopération avec l'organe de positionnement 18. De manière avantageuse, on peut prévoir que le bec 30 déborde au-delà du rebord 26 de manière à s'assurer que l'organe de positionnement 18 ne puisse coopérer qu'avec la première ou la deuxième encoches 28.In a particularly interesting way, it is found that the spout 30 is dimensioned so that the flange 26 can be housed under the spout 30 and that the latter can cover the flange 26. When the movable lever 20 is in its first position shown on the figure 2 , the rim 26 is no longer exposed to the positioning member 18. Thus, in this first position of the mobile lever 20, the positioning zone 16 defines two positions of the control part 10, by cooperation with the control member. Positioning 18. Advantageously, it is possible for spout 30 to protrude beyond flange 26 so as to ensure that positioning member 18 can cooperate only with first or second notches 28.

Le levier mobile 20 est donc susceptible d'évoluer entre une première position dans laquelle la zone de positionnement 16 définit deux positions de la pièce de commande 10, par coopération avec l'organe de positionnement 18, et une deuxième position dans laquelle la zone de positionnement 16 définit trois positions de la pièce de commande 10, par coopération avec l'organe de positionnement 18.The mobile lever 20 is therefore capable of changing between a first position in which the positioning zone 16 defines two positions of the control part 10, by cooperation with the positioning member 18, and a second position in which the zone of Positioning 16 defines three positions of the control part 10, by cooperation with the positioning member 18.

Une telle pièce de commande 10 peut avantageusement être mise en oeuvre dans un mécanisme de chronographe proposé dans le document WO2009/098307 . Le fonctionnement d'un tel chronographe est représenté schématiquement sur les figures 5 à 8 qui vont maintenant être décrites.Such a control part 10 can advantageously be implemented in a chronograph mechanism proposed in the document WO2009 / 098307 . The operation of such a chronograph is schematically represented on the Figures 5 to 8 which will now be described.

Après une remise à zéro, un mécanisme de chronographe incorporant une pièce de commande 10 selon l'invention, est dans la position de la figure 5, correspondant à la figure 1. Le levier mobile 20 est dans sa première position. Bien que nous ne décrirons pas ici en détails les éléments composant un mécanisme de chronographe, on peut voir que deux navettes 34 sont agencées solidairement et de manière coaxiale sur la pièce de commande 10. Pour réaliser les fonctions du chronographe, ces navettes 34 commandent le positionnement :

  • d'un frein 36 prévu pour appuyer sur une roue de compteur,
  • d'une bascule d'embrayage 38 prévue pour positionner un mobile d'embrayage, et
  • d'une bascule de marteaux 40 prévue pour positionner un ou plusieurs marteaux de remise à zéro.
After a reset, a chronograph mechanism incorporating a control part 10 according to the invention, is in the position of the figure 5 , corresponding to the figure 1 . The movable lever 20 is in its first position. Although we will not describe here in detail the elements making up a chronograph mechanism, we can see that two shuttles 34 are arranged jointly and coaxially on the control part 10. To perform the functions of the chronograph, these shuttles 34 control the positioning :
  • a brake 36 provided for pressing a counter wheel,
  • a clutch lever 38 provided for positioning a clutch mobile, and
  • a hammer rocker 40 provided for positioning one or more reset hammers.

En position de remise à zéro, l'organe de positionnement 18 est dans la deuxième encoche 28. Les marteaux sont en appui sur leur compteur respectif, le mobile d'embrayage est débrayé et le frein n'est pas en appui sur la roue de compteur.In reset position, the positioning member 18 is in the second notch 28. The hammers are resting on their respective counter, the clutch mobile is disengaged and the brake is not supported on the wheel of counter.

Pour enclencher une mesure, un utilisateur va exercer une action sur la portion d'entraînement 12, ce qui va faire pivoter la bascule 14 autour de son axe dans une première direction. Sous l'action de l'organe de positionnement 18, le levier mobile 20 va alors venir dans sa deuxième position et s'appuyer sur le bord 22b de l'échancrure 22. On est alors dans la position illustrée sur la figure 6, correspondant à la figure 2, juste avant le START. Une fois que le levier mobile 20 est dans sa deuxième position, la poursuite du pivotement de la bascule 14 permet que l'organe de positionnement 18 tombe directement dans la première encoche 24, sans passer par la troisième encoche 32. On passe donc directement d'une position RESET à une position START (figure 7, correspondant à la figure 3). Les marteaux sont levés, le mobile d'embrayage est embrayé et le frein n'est pas en appui sur la roue de compteur. On remarque que, le levier étant librement mobile, une fois que l'organe de positionnement 18 est dans la première encoche 24, il va être repoussé en direction de sa première position par l'organe de positionnement 18 mais ne sera pas nécessairement maintenu dans cette première position.To engage a measurement, a user will exert an action on the drive portion 12, which will rotate the latch 14 about its axis in a first direction. Under the action of the positioning member 18, the mobile lever 20 will then come into its second position and bear on the edge 22b of the notch 22. It is then in the position illustrated on the figure 6 , corresponding to the figure 2 , just before START. Once the movable lever 20 is in its second position, the continued pivoting of the rocker 14 allows the positioning member 18 to fall directly into the first notch 24, without passing through the third notch 32. It therefore passes directly from a RESET position to a START position ( figure 7 , corresponding to the figure 3 ). The hammers are raised, the clutch mobile is engaged and the brake is not supported on the counter wheel. Note that, the lever being freely movable, once the positioning member 18 is in the first notch 24, it will be pushed towards its first position by the positioning member 18 but will not necessarily be maintained in this first position.

Lorsqu'un utilisateur va ensuite exercer une action sur la portion d'entraînement 12 pour stopper la mesure, la bascule 14 va être entraînée autour de son axe dans une deuxième direction. Sous l'action de l'organe de positionnement 18, le levier mobile 20 va alors venir dans sa première position et s'appuyer sur le bord 22a de l'échancrure 22. La troisième encoche 32 ainsi défine peut recevoir l'organe de positionnement 18 pour positionner la pièce de commande 10 dans une position correspondant au STOP. Les marteaux sont levés, le mobile d'embrayage est débrayé et le frein est en appui sur la roue de compteur. On peut alors soit redémarrer la mesure ou remettre les compteurs à zéro. Dans ce dernier cas, on revient à la position initiale et une nouvelle mesure peut être immédiatement commencée, sans devoir revenir à la position STOP. De plus, c'est bien l'utilisateur qui fournit l'énergie nécessaire à relever les marteaux lors de l'enclenchement d'une mesure, assurant un fonctionnement précis.When a user will then exert an action on the drive portion 12 to stop the measurement, the latch 14 will be driven about its axis in a second direction. Under the action of the positioning member 18, the mobile lever 20 will then come into its first position and bear against the edge 22a of the notch 22. The third notch 32 thus deflected can receive the positioning member 18 to position the control part 10 in a position corresponding to the STOP. The hammers are raised, the clutch mobile is disengaged and the brake is supported on the counter wheel. We can then either restart the measurement or reset the counters. In the latter case, it returns to the initial position and a new measurement can be immediately started, without having to return to the STOP position. In addition, it is the user who provides the energy necessary to raise the hammers during the engagement of a measurement, ensuring accurate operation.

La présente description est proposée à titre d'illustration non limitative. L'homme du métier pourra envisager différentes adaptations sans sortir du cadre défini par les revendications. Par exemple, le levier mobile 20 pourrait également être solidaire de la bascule 14 et être monté mobile élastiquement en référence à cette bascule.This description is offered by way of non-limiting illustration. The skilled person may consider various adaptations without departing from the scope defined by the claims. For example, the mobile lever 20 could also be integral with the rocker 14 and be mounted elastically movable with reference to this rocker.
