Description

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne plus précisément un dispositif de commande de fonction ou de correction pour une pièce d'horlogerie.The present invention relates to the field of watchmaking. It relates more specifically to a function control device or correction for a timepiece.

Sur des montres comportant un nombre élevé de fonctions, les dispositifs de commande sont généralement constitués par des boutons-poussoirs disposés de part et d'autre de la couronne, sur les flancs de la boîte. Pour des raisons esthétiques, ou pour créer un effet surprenant, il peut être intéressant de remplacer ces boutons-poussoirs par des dispositifs de commande plus discrets, s'intégrant, par exemple, à la face supérieure de la boîte. La demande EP 1 580 626 décrit un tel dispositif équipant une montre comportant une boîte dans laquelle est logé un mouvement muni d'un mécanisme indicateur. Ce dispositif comprend un levier de commande situé à l'extérieur de la boîte et actionnable par l'utilisateur, un levier d'actionnement situé à l'intérieur de la boîte et coopérant avec le mécanisme indicateur, et une tige reliant entre eux rigidement les deux leviers et montée mobile en rotation à travers la boîte suivant un axe sensiblement perpendiculaire au plan général de la montre. Le pivotement du levier extérieur sous l'action de l'utilisateur entraîne en rotation, par l'intermédiaire de la tige, le levier d'actionnement qui coopère avec le mécanisme indicateur afin d'effectuer une correction. Le levier de commande est avantageusement situé dans une creusure ménagée dans une corne, afin d'être facilement accessible, tout en restant peu visible.On watches with a large number of functions, the control devices are generally constituted by pushbuttons arranged on either side of the crown, on the sides of the box. For aesthetic reasons, or to create a surprising effect, it may be interesting to replace these push buttons by more discreet control devices, integrating, for example, to the upper face of the box. Requirement EP 1,580,626 describes such a device equipping a watch comprising a box in which is housed a movement provided with an indicator mechanism. This device comprises a control lever located outside the box and operable by the user, an operating lever located inside the box and cooperating with the indicator mechanism, and a rod interconnecting between them rigidly. two levers and rotatably mounted through the box along an axis substantially perpendicular to the general plane of the watch. The pivoting of the outer lever under the action of the user rotates, via the rod, the actuating lever which cooperates with the indicator mechanism to perform a correction. The control lever is advantageously located in a recess in a horn, to be easily accessible, while remaining inconspicuous.

Le dispositif ainsi décrit constitue une alternative à un traditionnel bouton-poussoir, ou vient en complément, au cas ou les boutons-poussoirs ne suffiraient pas. Le dispositif selon l'invention remplit une même fonction, tout en s'intégrant encore mieux à la montre, puisque le levier de commande devient invisible.The device thus described is an alternative to a traditional push button, or comes in addition, in case the pushbuttons are not enough. The device according to the invention performs the same function, while integrating even better with the watch, since the control lever becomes invisible.

A cet effet, la présente invention concerne un dispositif de commande pour pièce d'horlogerie comportant une carrure délimitant un volume intérieur dans lequel est situé un mouvement, le dispositif comprenant un organe de transmission formé :

  • d'une tige montée mobile en rotation dans un trou traversant la carrure,
  • d'une première came située à l'intérieur du volume de la carrure, montée solidaire en rotation à une extrémité de la tige, et coopérant avec un levier de commande monté sur le mouvement lorsque l'organe de transmission tourne, et
  • d'une pièce située à l'extérieur du volume de la carrure, montée solidaire en rotation à l'autre extrémité de la tige, et comportant au moins une surface d'appui s'étendant sensiblement radialement,
For this purpose, the present invention relates to a control device for a timepiece comprising a middle part delimiting an internal volume in which a movement is located, the device comprising a transmission member formed:
  • a rod rotatably mounted in a hole through the middle part,
  • a first cam located inside the volume of the middle, mounted integral in rotation at one end of the rod, and cooperating with a control lever mounted on the movement when the transmission member rotates, and
  • a piece located outside the volume of the middle part, mounted to rotate with the other end of the rod, and having at least one bearing surface extending substantially radially,

Selon l'invention, la pièce d'horlogerie comporte en outre une lunette montée mobile en rotation sur la carrure, la lunette comportant une surface de contact agencée pour coopérer avec la surface d'appui lorsqu'elle tourne, de manière à entraîner l'organe de transmission en rotation.According to the invention, the timepiece further comprises a bezel mounted rotatably on the middle part, the bezel having a contact surface arranged to cooperate with the bearing surface when it rotates, so as to cause the transmission member in rotation.

Grâce à ces caractéristiques, le dispositif de commande selon l'invention permet de commander ou corriger une fonction à partir de la lunette, sans l'intervention de boutons-poussoirs. L'aspect esthétique de la montre est sensiblement amélioré, sans que la fonctionnalité en soit modifiée.Thanks to these characteristics, the control device according to the invention makes it possible to control or correct a function from the telescope, without the intervention of pushbuttons. The aesthetic appearance of the watch is significantly improved, without the functionality is changed.

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

  • les figures 1 et 2 sont des vues en coupe partielle, légèrement décalées angulairement l'une par rapport à l'autre, d'une montre équipée du dispositif selon l'invention,
  • les figures 3 et 4 sont des vues en coupe partielle selon des plans sensiblement parallèles au plan général de la montre, d'un tel dispositif, et
  • la figure 5 est une vue en perspective du dispositif selon l'invention.
Other features and advantages of the present invention will emerge more clearly from the following detailed description of an exemplary embodiment of the corrector device according to the invention, this example being given for purely illustrative and non-limiting purposes only, in connection with the attached drawing in which:
  • FIGS. 1 and 2 are partial sectional views, slightly angularly offset relative to one another, of a watch equipped with the device according to the invention,
  • FIGS. 3 and 4 are views in partial section along planes substantially parallel to the general plane of the watch, of such a device, and
  • Figure 5 is a perspective view of the device according to the invention.

La montre représentée partiellement sur les figures 1 et 2, comporte classiquement une boîte 10 formée d'une carrure 12 et d'un fond 14 délimitant ensemble un volume intérieur 16 dans lequel est monté un mouvement 18 par l'intermédiaire d'un cercle d'encageage 20. Le mouvement 18 s'étend dans un plan P sensiblement parallèle au plan défini par le fond 14. Ce mouvement peut être purement mécanique ou de type électromécanique alimenté par une source d'énergie électrique non représentée. Un levier de commande, non représenté, d'une fonction marche / arrêt d'un chronomètre est monté sur le mouvement 18. Ce levier coopère avec une pièce intermédiaire 24 montée coulissante dans une ouverture 26 traversant le cercle d'encageage 20 et destinée à permettre l'accès au levier de commande, depuis la carrure 12, à travers le cercle d'encageage 20. L'ouverture 26 sera mieux décrite ultérieurement, en regard de la figure 3. Une glace 27 est montée de manière étanche sur la carrure 12.The watch partially shown in FIGS. 1 and 2, conventionally comprises a box 10 formed of a middle part 12 and a bottom 14 defining together an interior volume 16 in which is mounted a movement 18 via a circle of The movement 18 extends in a plane P substantially parallel to the plane defined by the bottom 14. This movement may be purely mechanical or electromechanical type powered by a source of electrical energy not shown. A control lever, not shown, of a start / stop function of a stopwatch is mounted on the movement 18. This lever cooperates with an intermediate piece 24 slidably mounted in an opening 26 passing through the casing ring 20 and intended to allow access to the control lever, from the middle 12, through the casing ring 20. The opening 26 will be better described later, with reference to Figure 3. A mirror 27 is mounted in a sealed manner on the middle part 12.

La montre représentée sur les figures 1 et 2 comprend, en outre, un dispositif de commande 28, destiné à coopérer avec le levier de commande, et formé d'une lunette 30 et d'un organe de transmission 31. A cet effet, la carrure 12 comporte, dans sa portion supérieure, un dégagement 32 sensiblement circulaire formant une surface d'appui 34, parallèle au plan P, et une surface de guidage 35 perpendiculaire au plan P, sur lesquelles la lunette 30 est montée mobile en rotation selon une technique bien connue de l'homme de métier. Un ressort de rappel, non visible sur les figures 1 et 2, ramène la lunette 30 à sa position initiale après rotation. Dans le mode de réalisation présenté, la lunette 30 est formée de deux parties 30a et 30b, solidaires l'une de l'autre, la première assurant le montage sur la carrure 12, et la deuxième s'étendant sensiblement radialement autour de la glace 27. En variante, la lunette 30 pourrait être monobloc.The watch shown in FIGS. 1 and 2 further comprises a control device 28 intended to cooperate with the control lever and formed by a telescope 30 and a transmission member 31. For this purpose, the middle part 12 comprises, in its upper portion, a substantially circular clearance 32 forming a bearing surface 34, parallel to the plane P, and a guide surface 35 perpendicular to the plane P, on which the bezel 30 is rotatably mounted according to a technique well known to those skilled in the art. A return spring, not visible in Figures 1 and 2, returns the bezel 30 to its initial position after rotation. In the embodiment shown, the bezel 30 is formed of two parts 30a and 30b, integral with each other, the first assuring the mounting on the middle part 12, and the second extending substantially radially around the ice 27. Alternatively, the telescope 30 could be monobloc.

L'organe de transmission 31 comporte une tige cylindrique 36, montée mobile en rotation à l'intérieur d'un trou 38 d'axe XX sensiblement perpendiculaire au plan P, traversant la carrure 12, depuis la surface d'appui 34 jusqu'à une cavité 40, ménagée à l'intérieur de la carrure 12. La cavité 40 débouche elle même sur le volume intérieur 16, en regard de l'ouverture 26. Le trou 38 se prolonge, au-delà de la cavité 40, dans la carrure 12, par un trou borgne 42 qui lui est coaxial.The transmission member 31 comprises a cylindrical rod 36, rotatably mounted inside a hole 38 of axis XX substantially perpendicular to the plane P, passing through the middle part 12, from the bearing surface 34 to a cavity 40, formed inside the middle part 12. The cavity 40 opens itself on the internal volume 16, facing the opening 26. The hole 38 extends beyond the cavity 40, in the 12, by a blind hole 42 which is coaxial with it.

La tige cylindrique 36, présente une gorge 44 dans laquelle est monté un joint d'étanchéité 46. Elle comporte une première extrémité à section circulaire engagée dans le trou 42 de manière à optimiser son guidage en rotation suivant l'axe XX. Sa portion située à l'intérieur de la cavité 40 comporte, en outre, un tronçon à section carrée sur lequel est montée une première came 48, percée d'un trou à section carrée 50. En variante, ledit tronçon et la came 48 sont à section triangulaire ou hexagonale, ou toute forme adaptée à la transmission d'un couple. La hauteur de la cavité 40 est sensiblement égale à la hauteur de la came 48 de manière à ce que cette dernière puisse s'y loger, tout en étant bloquée axialement sur la tige 36. En variante, la came 48 est bloquée axialement en direction du trou 42 par un anneau élastique, et, en direction du trou 38, par la portée entre le tronçon de la tige 36 à section carrée et la portion à section cylindrique. Dans ce cas, la hauteur de la cavité 40 est quelconque.The cylindrical rod 36, has a groove 44 in which is mounted a seal 46. It has a first end circular section engaged in the hole 42 so as to optimize its rotational guidance along the axis XX. Its portion located inside the cavity 40 further comprises a section with a square section on which is mounted a first cam 48, pierced with a square section hole 50. In a variant, said section and the cam 48 are triangular or hexagonal section, or any form adapted to the transmission of a couple. The height of the cavity 40 is substantially equal to the height of the cam 48 so that the latter can be housed there, while being locked axially on the rod 36. In a variant, the cam 48 is locked axially in the direction the hole 42 by an elastic ring, and, in the direction of the hole 38, by the bearing between the section of the rod 36 of square section and the portion with cylindrical section. In this case, the height of the cavity 40 is arbitrary.

La came 48 est représentée en coupe selon un plan sensiblement parallèle au plan P sur la figure 3. De forme sensiblement allongée, la came 48 est montée décentrée sur la tige 36. Elle comprend une première extrémité formant un méplat 52, et une seconde formant une butée 54 destinée à limiter la course en rotation de la came 48 à l'intérieur de la cavité 40. Lorsque la butée 54 est en appui sur la paroi latérale de la cavité 40, le méplat 52 vient au contact de la pièce intermédiaire 24 logée dans l'ouverture 26. Par ailleurs, l'ouverture 26 forme une portion de cercle dans laquelle la came 48 est libre de se déplacer, sur un certain secteur angulaire, lorsqu'elle tourne autour de l'axe XX.The cam 48 is shown in section along a plane substantially parallel to the plane P in FIG. 3. With a substantially elongated shape, the cam 48 is mounted off center on the rod 36. It comprises a first end forming a flat portion 52, and a second forming a stop 54 intended to limit the rotational travel of the cam 48 inside the cavity 40. When the abutment 54 bears against the side wall of the cavity 40, the flat 52 comes into contact with the intermediate piece 24 housed in the opening 26. Furthermore, the opening 26 forms a portion of a circle in which the cam 48 is free to move, over a certain angular sector, when it rotates about the axis XX.

La deuxième extrémité de la tige 36 est formée d'une deuxième came 56 située à l'extérieur de la carrure 12 et s'étendant partiellement sur la surface d'appui 34. A cet effet, un dégagement circulaire 58 ménagé dans la face inférieure de la lunette 30, forme un logement 60 pour la came 56. Avantageusement, la came 56 et la tige 36 forment une seule pièce réalisée par décolletage ou usinage. En variante, la came 56 pourrait être collée ou soudée à la tige 36.The second end of the rod 36 is formed of a second cam 56 located outside the middle part 12 and extending partially on the bearing surface 34. For this purpose, a circular recess 58 formed in the lower face of the bezel 30, forms a housing 60 for the cam 56. Advantageously, the cam 56 and the rod 36 form a single piece produced by cutting or machining. Alternatively, the cam 56 could be glued or welded to the rod 36.

La came 56 et le dégagement 58 sont représentés en coupe selon un plan sensiblement parallèle au plan P sur la figure 4. La came 56 forme sensiblement un huit dont l'un des lobes est centré sur l'axe XX, et l'autre lobe forme une surface d'appui 59 s'étendant sensiblement radialement. Le dégagement 58 comporte un décrochement 61 formant une surface de contact 62, s'étendant perpendiculairement au plan P, et destinée à coopérer avec la surface d'appui 59 de manière à entraîner la came 56 en rotation lorsque la lunette 30 tourne.The cam 56 and the clearance 58 are shown in section along a plane substantially parallel to the plane P in FIG. 4. The cam 56 forms substantially an eight of which one of the lobes is centered on the axis XX, and the other lobe forms a bearing surface 59 extending substantially radially. The clearance 58 comprises a recess 61 forming a contact surface 62, extending perpendicular to the plane P, and intended to cooperate with the bearing surface 59 so as to drive the cam 56 in rotation when the telescope 30 rotates.

Le montage du dispositif de commande 28 selon l'invention s'opère de la façon suivante. La came 48 est positionnée dans la cavité 40, son trou à section carrée 50 étant disposé en regard des trous 38 et 42. La tige 36, solidaire de la came 56, est introduite dans le trou traversant 38, jusqu'au trou borgne 42, à travers le trou à section carrée 50. Puis la lunette 30 est montée de manière à ce que la came 56 prenne place à l'intérieur du logement 60. L'orientation relative des cames 48 et 56 est telle que, lorsque la butée 54 est en appui sur la paroi de la cavité 40, l'axe longitudinal de la came 56 est sensiblement perpendiculaire au déplacement de la lunette 30. La tige 36 est bloquée axialement, dans un sens par la came 56, et dans l'autre sens par la lunette 30.The mounting of the control device 28 according to the invention operates as follows. The cam 48 is positioned in the cavity 40, its square section hole 50 being disposed opposite the holes 38 and 42. The rod 36, integral with the cam 56, is inserted into the through hole 38 to the blind hole 42 through the hole with square section 50. Then the telescope 30 is mounted so that the cam 56 takes place inside the housing 60. The relative orientation of the cams 48 and 56 is such that, when the stop 54 is supported on the wall of the cavity 40, the longitudinal axis of the cam 56 is substantially perpendicular to the displacement of the telescope 30. The rod 36 is locked axially, in one direction by the cam 56, and in the other meaning by the telescope 30.

Le dispositif de commande selon l'invention est utilisé pour commander le départ et l'arrêt d'un chronomètre. En variante, il pourrait être utilisé pour corriger une indication, telle qu'un jour de la semaine, ou des phases de lune, ou commander toute autre fonction, telle que l'armage d'un ressort de compte à rebours. Son fonctionnement est le suivant. Lorsque la lunette 30 est dans sa position initiale, la surface de contact 62 est située au voisinage de la came 56 et le méplat 52 vient au contact de la pièce intermédiaire 24. Lorsque l'utilisateur actionne la lunette 30 en rotation, la surface de contact 62 vient exercer une poussée sur la surface d'appui 59, faisant ainsi pivoter la came 56 autour de l'axe XX. Ce mouvement de pivotement est transmis à la came 48 par l'intermédiaire de la tige 36. La came 48 presse alors sur la pièce intermédiaire 24, qui vient actionner le levier de commande de fonction, démarrant ainsi le chronomètre. La forme et dimension de l'ouverture 26 sont telles que le méplat 52 vient en butée sur la paroi de l'ouverture 26 après avoir actionné la pièce intermédiaire 24. Lorsque l'utilisateur relâche la lunette 30, celle-ci revient à sa position initiale grâce à l'action du ressort de rappel. De son côté, l'organe de transmission 31 revient à sa position initiale sous l'action du levier de commande, muni d'un ressort de rappel.The control device according to the invention is used to control the start and stop of a stopwatch. Alternatively, it could be used to correct an indication, such as a day of the week, or moon phases, or to control any other function, such as winding a countdown spring. Its operation is as follows. When the telescope 30 is in its initial position, the contact surface 62 is located in the vicinity of the cam 56 and the flat 52 comes into contact with the intermediate part 24. When the user actuates the telescope 30 in rotation, the surface of contact 62 comes to exert a thrust on the bearing surface 59, thereby rotating the cam 56 about the axis XX. This pivoting movement is transmitted to the cam 48 via the rod 36. The cam 48 then presses on the intermediate piece 24, which actuates the function control lever, thus starting the stopwatch. The shape and size of the opening 26 are such that the flat 52 abuts the wall of the opening 26 after having actuated the intermediate piece 24. When the user releases the telescope 30, the latter returns to its position initial action by the action of the return spring. For its part, the transmission member 31 returns to its initial position under the action of the control lever, provided with a return spring.

On notera qu'un deuxième dispositif de commande selon l'invention peut être monté symétriquement au premier. Un tel agencement est représenté en perspective sur la figure 5. La lunette 30 comporte un dégagement circulaire 58 formant un logement 60 dans lequel sont logées une première came 56 et une deuxième came 64 appartenant respectivement à un premier organe de transmission 31 et à un deuxième organe de transmission 66. Le logement comporte un premier décrochement 61 et un deuxième décrochement 68 formant une première surface de contact 62 et une deuxième surface de contact 70 disposées en regard l'une de l'autre de manière à actionner les organes de transmission 31 et 66 respectivement dans un sens de rotation et dans l'autre. Le deuxième organe de transmission 66, actionne, par exemple, la remise à zéro du chronomètre.Note that a second control device according to the invention can be mounted symmetrically to the first. Such an arrangement is shown in perspective in Figure 5. The bezel 30 has a circular recess 58 forming a housing 60 in which are housed a first cam 56 and a second cam 64 respectively belonging to a first transmission member 31 and a second transmission member 66. The housing comprises a first recess 61 and a second recess 68 forming a first contact surface 62 and a second contact surface 70 disposed opposite one another so as to actuate the transmission members 31 and 66 respectively in one direction of rotation and in the other. The second transmission member 66 actuates, for example, resetting the stopwatch.

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 de métier, sans sortir du cadre de la présente invention telle que définie par les revendications annexées.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 present invention such as defined by the appended claims.

On notera, par exemple, que la came 56 solidaire de l'extrémité de la tige 36 située à l'extérieur de la carrure 12, peut être remplacée par une roue dentée. La lunette tournante 30 est alors munie d'un secteur denté se substituant à la surface de contact 62, et destiné à coopérer avec la roue dentée de manière à entraîner l'organe de transmission 31 en rotation. De manière générale, toute pièce comportant au moins une surface d'appui s'étendant sensiblement radialement de manière à coopérer avec au moins une surface de contact appartenant à la lunette, peut être montée à l'extrémité extérieure de la tige 36 de manière à l'entraîner en rotation.It will be noted, for example, that the cam 56 integral with the end of the rod 36 located outside the middle part 12, can be replaced by a toothed wheel. The rotating bezel 30 is then provided with a toothed sector which is substituted for the contact surface 62, and intended to cooperate with the toothed wheel so as to drive the transmission member 31 in rotation. In general, any part comprising at least one bearing surface extending substantially radially so as to cooperate with at least one contact surface belonging to the telescope, may be mounted at the outer end of the rod 36 so as to rotate it.

Par ailleurs, le dispositif de commande selon l'invention comporte une tige 36 traversant la carrure 12 selon un axe XX sensiblement perpendiculaire au plan P défini par le fond. En variante, la tige 36 pourrait s'étendre parallèlement au plan P en étant engagée radialement dans la carrure 12.Furthermore, the control device according to the invention comprises a rod 36 passing through the middle part 12 along an axis XX substantially perpendicular to the plane P defined by the bottom. As a variant, the rod 36 could extend parallel to the plane P while being engaged radially in the middle part 12.

Enfin, dans le mode de réalisation présenté, le mouvement 18 est monté dans la boîte 10 par l'intermédiaire d'un cercle d'encageage 20. Il va de soi que l'ensemble des possibilités de montage du mouvement dans la boîte est compatible avec le dispositif de commande selon l'invention. En particulier, en l'absence de cercle d'encageage, la came 48 agit directement sur le levier de commande de fonction sans pièce intermédiaire 24.Finally, in the embodiment shown, the movement 18 is mounted in the box 10 by means of a casing ring 20. It goes without saying that all the possibilities for mounting the movement in the box is compatible with the control device according to the invention. In particular, in the absence of a casing ring, the cam 48 acts directly on the function control lever without an intermediate part 24.
