Description

Domaine techniqueTechnical area

La présente invention concerne une pièce d'horlogerie, comprenant :

  • une source d'énergie,
  • un organe de commande susceptible de se déplacer entre une première et une deuxième positions définies par un mécanisme de réserve de marche,
  • un mécanisme additionnel,
  • un bec de déclenchement dont le déplacement entraîne le déclenchement du mécanisme additionnel, et
  • un organe de déclenchement destiné à être actionné pour coopérer avec ledit bec de déclenchement pour déclencher le mécanisme additionnel.
The present invention relates to a timepiece, comprising:
  • a source of energy,
  • a control member capable of moving between a first and a second position defined by a power reserve mechanism,
  • an additional mechanism,
  • a trigger nose whose movement triggers the additional mechanism, and
  • a trigger member adapted to be actuated to cooperate with said trigger nose to trigger the additional mechanism.

Le fonctionnement d'une telle pièce d'horlogerie munie d'un mécanisme additionnel est ainsi sécurisé, particulièrement pour le cas où la source d'énergie sert à la fois à l'alimentation du mécanisme additionnel et à l'alimentation du rouage de finissage du mouvement. En effet, lorsque la source d'énergie atteint une réserve de marche prédéfinie, à partir de laquelle il est préférable que l'énergie restante serve uniquement à l'alimentation du rouage de finissage, le mécanisme additionnel ne peut plus être actionné. Une telle pièce d'horlogerie trouve une application particulièrement intéressante dans le cas où le mécanisme additionnel est un mécanisme de sonnerie. En effet, lors de son fonctionnement, une sonnerie consomme beaucoup d'énergie, ce qui peut être au préjudice du rouage de finissage.The operation of such a timepiece provided with an additional mechanism is thus secured, particularly in the case where the energy source serves both to feed the additional mechanism and to feed the finishing gear. some movement. Indeed, when the energy source reaches a predefined power reserve, from which it is preferable that the remaining energy only serve to feed the gear train, the additional mechanism can no longer be operated. Such a timepiece finds a particularly interesting application in the case where the additional mechanism is a striking mechanism. Indeed, during its operation, a bell consumes a lot of energy, which can be to the detriment of the gear train.

Etat de la techniqueState of the art

Les mécanismes de sonnerie permettant d'indiquer, sur demande, l'heure à la minute près, au moyen de coups frappés par deux marteaux sur deux timbres différents sont bien connus de l'homme du métier. Ils peuvent aussi permettre de sonner au passage les heures et les quarts. Les marteaux sont actionnés par des levées qui sont soulevées par un mécanisme de sonnerie. Celui-ci comprend une pièce des heures, une des quarts et une des minutes, dotées respectivement de douze, trois et quatorze dents pour sonner les heures, les quarts et les minutes.The striking mechanisms for indicating, on demand, the hour to the minute by means of blows struck by two hammers on two different stamps are well known to those skilled in the art. They can also ring the hours and quarters. The hammers are operated by lifts that are raised by a striking mechanism. This includes a room of hours, a quarter and a minute, each with twelve, three and fourteen teeth to ring the hours, quarters and minutes.

Dans les mécanismes de sonnerie de l'état de la technique, afin de régler le déplacement de ces pièces, une came des heures est disposée sur une étoile à douze dents, avançant d'un pas par heure, tandis qu'une came des quarts et une autre des minutes peuvent être ajustées sur un tigeron. Trois bascules, dotées chacune d'un puiseur coopérant avec ces cames, permettent de déterminer la course des pièces des heures, des quarts et des minutes et d'ajuster le nombre de coups sonnés.In the ringing mechanisms of the state of the art, in order to adjust the movement of these parts, an hour cam is arranged on a star with twelve teeth, advancing one step per hour, while a quarter cam and another minutes can be adjusted on a burrow. Three scales, each with a bucket cooperating with these cams, allow to determine the stroke of the parts of the hours, quarters and minutes and to adjust the number of shots sounded.

On trouvera d'autres détails sur ce genre de complications, notamment sur la force motrice de la répétition ou sur l'étape de décrochement, c'est-à-dire sur le déclenchement de la sonnerie, dans le livre " Théorie de l'horlogerie" de Reymondin et al, Fédération des Ecoles Techniques, 1998, ISBN 2-940025-10-X, pages 219 à 224 .Further details on this kind of complications can be found, especially on the driving force of the repetition or on the step of recess, that is to say on the triggering of the ring, in the book " Theory of Watchmaking "by Reymondin et al, Federation of Technical Schools, 1998, ISBN 2-940025-10-X, pages 219-224 .

Le document EP1760545 propose une pièce d'horlogerie telle que proposée ci-dessus, dans lequel le mécanisme additionnel est un mécanisme de sonnerie. Plus particulièrement, le déclenchement d'une sonnerie nécessite le débrayage d'une bascule d'embrayage afin de débloquer les râteaux de sonnerie et de permettre à ceux-ci de prendre leur information sur leur came respective. Un système de blocage est en outre prévu afin d'empêcher le débrayage de la bascule d'embrayage, lorsque la réserve de marche du barillet est inférieure à la valeur prédéfinie. La solution proposée est adaptée à un mouvement dans lequel la source d'énergie est éloignée de l'organe de déclenchement. Toutefois, outre sa complexité, elle présente également l'inconvénient d'être exclusivement applicable au mécanisme de sonnerie tel que décrit dans ce document.The document EP1760545 proposes a timepiece as proposed above, wherein the additional mechanism is a striking mechanism. More particularly, the triggering of a ring requires disengagement of a clutch rocker to unlock the ring rakes and allow them to take their information on their respective cam. A locking system is further provided to prevent disengagement of the clutch rocker, when the power reserve of the barrel is less than the preset value. The proposed solution is adapted to a movement in which the energy source is remote from the triggering member. However, in addition to its complexity, it also has the disadvantage of being exclusively applicable to the striking mechanism as described in this document.

La présente invention a pour objet de proposer un système de sécurité particulièrement fiable et susceptible d'être appliqué à d'autres mécanismes de sonnerie et plus généralement à d'autres mécanismes additionnels.The present invention aims to provide a particularly reliable security system and may be applied to other striking mechanisms and more generally to other additional mechanisms.

Divulgation de l'inventionDisclosure of the invention

De manière plus précise, l'invention porte sur une pièce d'horlogerie tel que mentionnée au premier paragraphe ci-dessus, dans lequel l'organe de déclenchement est susceptible d'occuper une première position dans laquelle il peut coopérer avec le bec et une deuxième position dans laquelle il ne peut pas coopérer avec le bec. En outre, l'organe de commande est agencé de manière à coopérer avec l'organe de déclenchement et à l'amener dans sa première ou dans sa deuxième positions, selon que ledit organe de commande est dans sa première ou dans sa deuxième positions.More specifically, the invention relates to a timepiece as mentioned in the first paragraph above, wherein the triggering member is likely to occupy a first position in which it can cooperate with the beak and a second position in which it can not cooperate with the beak. In addition, the control member is arranged to cooperate with the trigger member and to bring it into its first or second positions, according to whether said control member is in its first or in its second positions.

Selon un mode de réalisation avantageux, l'organe de commande comporte une bascule et une came entraînée par le barillet, ladite bascule pouvant occuper soit une première soit une deuxième positions.According to an advantageous embodiment, the control member comprises a rocker and a cam driven by the barrel, said rocker can occupy either a first or a second positions.

Cette came peut être un doigt monté sur un mobile pivotant sur moins de 360° entre l'armage maximal et le désarmage maximal du barillet.This cam can be a finger mounted on a mobile pivoting less than 360 ° between the maximum arming and maximum disarming of the barrel.

En outre, la bascule peut comporter un ergot avec lequel coopère la came pour faire passer la bascule de l'une à l'autre des première et deuxième positions.In addition, the latch may comprise a lug with which the cam cooperates to move the latch from one to the other of the first and second positions.

Selon un mode de réalisation préféré, l'organe de déclenchement comporte un levier actionné par un poussoir, se terminant par une portion articulée destinée à coopérer avec l'organe de commande.According to a preferred embodiment, the trigger member comprises a lever actuated by a pusher, ending in an articulated portion intended to cooperate with the control member.

L'organe de commande peut en outre comporter un élément en saillie coopérant avec une échancrure ménagée dans la portion articulée.The control member may further comprise a projecting element cooperating with a recess formed in the articulated portion.

Des éléments de guidage peuvent encore être agencés de manière à coopérer avec l'organe de déclenchement.Guiding elements may also be arranged to cooperate with the triggering member.

Brève description des dessinsBrief description of the drawings

D'autres caractéristiques de la présente invention apparaîtront plus clairement à la lecture de la description qui va suivre, faite en référence au dessin annexé, dans lequel les figures 1 et 2 présentent le mécanisme selon l'invention, respectivement dans ses première et deuxième positions.Other features of the present invention will appear more clearly on reading the description which follows, made with reference to the appended drawing, in which the figures 1 and 2 present the mechanism according to the invention, respectively in its first and second positions.

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

On a représenté au dessin les éléments essentiels pour la compréhension de l'invention, d'un mécanisme de sonnerie d'un mouvement de pièce d'horlogerie. Ces éléments sont montés sur des ponts ou platine du mouvement, sans qu'il soit besoin de le préciser ultérieurement. Le mécanisme de sonnerie comprend une source d'énergie, typiquement un barillet, pour l'alimenter. Ce barillet peut également servir à l'alimentation d'un rouage de finissage dont est muni le mouvement pour afficher le temps courant.The drawing shows the essential elements for the understanding of the invention, a striking mechanism of a timepiece movement. These elements are mounted on bridges or platinum movement, without need to specify later. The striking mechanism includes a power source, typically a barrel, for powering it. This barrel can also be used for food a finishing wheel which is provided with the movement to display the current time.

Pour le déclenchement sur demande d'une sonnerie, le mécanisme comporte un organe de déclenchement 10. Selon un mode de réalisation préféré, l'organe de déclenchement 10 se termine par un poussoir 12 actionnable depuis l'extérieur du mouvement, sur lequel un utilisateur exerce une pression pour provoquer une sonnerie. Ce poussoir 12 est monté coulissant à la périphérie du mouvement, selon une direction essentiellement radiale.For triggering on demand a ring, the mechanism comprises a trigger member 10. According to a preferred embodiment, the trigger member 10 ends with a pusher 12 operable from outside the movement, on which a user press to make a ring. This pusher 12 is slidably mounted at the periphery of the movement, in a substantially radial direction.

Le poussoir 12 entraîne, dans ses déplacements, un doigt 14 agencé pour actionner le mécanisme de sonnerie. Dans l'exemple proposé, le doigt 14 est susceptible de coopérer avec un bec 16 dont le déplacement va entraîner le début de l'ensemble des actions qui se succèdent au cours du déroulement d'une sonnerie.The pusher 12 causes, in its movements, a finger 14 arranged to actuate the striking mechanism. In the proposed example, the finger 14 is likely to cooperate with a spout 16 whose movement will cause the beginning of all the actions that follow one another during the course of a ring.

Le poussoir 12 se prolonge par un levier 18 dont l'extrémité opposée au poussoir, se situe avantageusement, comme on le comprendra par la suite, à proximité du barillet du mécanisme de sonnerie. Pour son guidage, le levier 18 est maintenu en appui contre un pont 20 par un ressort 22. De manière avantageuse, le ressort 22 permet également le retour du poussoir à sa position de repos après que l'utilisateur l'a actionné. On notera que, comme illustré sur les figures, le poussoir 12, le doigt 14 et le levier 18 sont réalisés en une seule pièce.The pusher 12 is extended by a lever 18, the end opposite the pusher, is advantageously, as will be understood later, near the barrel of the striking mechanism. For its guidance, the lever 18 is held in abutment against a bridge 20 by a spring 22. Advantageously, the spring 22 also allows the return of the pusher to its rest position after the user has actuated. Note that, as shown in the figures, the pusher 12, the finger 14 and the lever 18 are made in one piece.

L'extrémité du levier 18 opposée au poussoir se termine par une portion articulée 26. Plus particulièrement, la portion 26 pivote librement à l'extrémité du levier. Elle comporte une échancrure 28 ménagée à sa périphérie, définissant une première et une deuxième parois, orientées de manière à ce qu'un appui contre elles entraînent, respectivement, un pivotement de la portion articulée 26 dans le sens horaire et dans le sens antihoraire.The end of the lever 18 opposite the pusher ends in an articulated portion 26. More particularly, the portion 26 pivots freely at the end of the lever. It comprises a notch 28 formed at its periphery, defining a first and a second wall, oriented so that a bearing against them respectively cause a pivoting of the articulated portion 26 in the clockwise direction and in the counterclockwise direction.

Le mécanisme comprend également un organe de commande 32 susceptible de se déplacer entre une première et une deuxième positions définies par un mécanisme de réserve de marche et correspondant respectivement à une réserve de marche supérieure et inférieure à une réserve de marche prédéfinie de la source d'énergie. Selon le mode de réalisation proposé, l'organe de commande 32 comporte une came entraînée par le barillet et dont la position est caractéristique de la réserve de marche du barillet. La came est avantageusement un doigt 34 monté sur un mobile pivotant sur moins de 360° entre l'armage maximal et le désarmage maximal du barillet.The mechanism also comprises a control member 32 able to move between a first and a second position defined by a power reserve mechanism and respectively corresponding to a power reserve greater than and less than a predefined power reserve of the source of power. energy. According to the proposed embodiment, the control member 32 comprises a cam driven by the barrel and whose position is characteristic of the power reserve of the barrel. The cam is advantageously a finger 34 mounted on a mobile pivoting less than 360 ° between the maximum arming and maximum disarming of the barrel.

L'organe de commande comporte encore une bascule 36 destinée à coopérer, d'une part, avec le doigt 34 et, d'autre part, avec la portion articulée 26. La bascule 36 est dotée, à sa périphérie, d'un premier 38 et d'un deuxième 40 logements, avec lesquels travaille un ressort sautoir 42, définissant ainsi une première et une deuxième positions que peut occuper la bascule 36. La bascule 36 est encore munie d'un ergot définissant une première 44 et une deuxième 45 faces, avec lequel coopère le doigt 34. Le doigt 34 est positionné de manière à coopérer avec l'une ou l'autre des deux faces 44 ou 45 lorsque la réserve de marche du barillet atteint une valeur prédéfinie, tant au cours de son désarmage que de son armage. Typiquement, la valeur prédéfinie peut être vingt-quatre heures de marche pour le rouage de finissage si le mouvement comporte un barillet unique pour le finissage et pour la sonnerie. Un élément en saillie, tel qu'une goupille 46 est chassée dans la bascule 36 et est positionnée afin de coopérer avec l'échancrure 28 de la portion articulée 26.The control member further comprises a rocker 36 intended to cooperate, on the one hand, with the finger 34 and, on the other hand, with the articulated portion 26. The rocker 36 is provided, at its periphery, with a first 38 and a second 40 housings, with which works a spring jumper 42, thus defining a first and a second positions that can occupy the flip-flop 36. The flip-flop 36 is further provided with a lug defining a first 44 and a second 45 face, with which the finger 34 cooperates. The finger 34 is positioned to cooperate with one or the other of the two faces 44 or 45 when the power reserve of the barrel reaches a predefined value, both during its disarming than his armor. Typically, the preset value can be twenty-four hours of walking for the finishing gear if the movement has a single barrel for finishing and for ringing. A protruding element such as a pin 46 is driven into the rocker 36 and is positioned to cooperate with the notch 28 of the articulated portion 26.

Ainsi, en fonctionnement, lorsque la réserve de marche du barillet est supérieure à la valeur prédéfinie (voir figure 1), le ressort sautoir 42 coopère avec le premier logement 38 et maintient la bascule 36 dans sa première position. La goupille 46 appuie sur la première paroi de l'échancrure 28, ce qui, conjugué au guidage du levier par le ressort 22 et le pont 20, dispose le poussoir 12 dans sa première position. Lorsque l'utilisateur de la montre exerce une pression sur le poussoir 12, le doigt 14 va croiser le bec 16 et provoquer le déclenchement d'une sonnerie.Thus, in operation, when the power reserve of the barrel is greater than the preset value (see figure 1 ), the jumper spring 42 cooperates with the first housing 38 and keeps the rocker 36 in its first position. The pin 46 bears on the first wall of the notch 28, which, combined with the guide of the lever by the spring 22 and the bridge 20, has the pusher 12 in its first position. When the user of the watch exerts pressure on the pusher 12, the finger 14 will cross the spout 16 and cause the triggering of a ring.

Lorsque le barillet se dévide, le doigt 34 tourne dans le sens antihoraire en référence aux figures. Quand la réserve de marche devient inférieure à la valeur prédéfinie, le doigt 34 pousse la face 44. La bascule 36 pivote dans le sens horaire et, sous l'action du ressort sautoir 42, elle est ainsi amenée à sa deuxième position. La goupille 46 entre en contact avec la deuxième paroi de l'échancrure 28 et la pousse. Cette pression, conjuguée au guidage du levier par le ressort 22 et le pont 20, éloigne le poussoir du bec 16 et l'amène dans sa deuxième position. Lorsque l'utilisateur de la montre exerce une pression sur le poussoir 12, le doigt 14 ne va pas croiser le bec 16 et ne va donc pas provoquer le déclenchement d'une sonnerie.When the barrel is unwound, the finger 34 rotates counterclockwise with reference to the figures. When the power reserve becomes less than the preset value, the finger 34 pushes the face 44. The flip-flop 36 pivots clockwise and, under the action of the jumper spring 42, it is thus brought to its second position. The pin 46 comes into contact with the second wall of the notch 28 and pushes it. This pressure, combined with the guidance of the lever by the spring 22 and the bridge 20, moves the pusher from the spout 16 and brings it to its second position. When the user of the watch exerts pressure on the pusher 12, the finger 14 will not cross the spout 16 and therefore will not cause the triggering of a ring.

Lors de l'armage du barillet, lorsque la réserve de marche redevient supérieure à la valeur prédéfinie, le doigt 34 est entraîné dans le sens horaire et pousse la face 45, ramenant ainsi la bascule et le poussoir dans leur première position.When winding the barrel, when the power reserve becomes greater than the preset value, the finger 34 is driven clockwise and pushes the face 45, thus reducing the rocker and the pusher in their first position.

Ainsi est proposé un mécanisme de sonnerie munie d'une sécurité permettant de désactiver la sonnerie lorsque la source d'énergie ne dispose plus que d'une réserve de marche inférieure à une valeur limite. Le mécanisme selon l'invention est particulièrement simple et fiable en agissant directement sur l'organe de déclenchement.Thus is proposed a striking mechanism provided with a security to disable the ring when the power source has more than a power reserve less than a limit value. The mechanism according to the invention is particularly simple and reliable by acting directly on the trigger member.

Bien que la description ci-dessus ait été faite en référence à un mécanisme de sonnerie, l'homme du métier pourra adapter les différents éléments fonctionnels de la sécurité à tout mécanisme additionnel pouvant être déclenché par le déplacement d'un bec de déclenchement coopérant avec un organe de déclenchement. Particulièrement, l'organe de déclenchement peut être une roue à rochet d'une roue à colonne d'un mécanisme de chronographe, le bec de déclenchement étant déplacé par l'actionnement d'un poussoir de commande du crochet d'entraînement sans toutefois sortir du cadre de l'invention, comme définie par les revendications.Although the above description has been made with reference to a striking mechanism, those skilled in the art will be able to adapt the different functional elements of safety to any additional mechanism that can be triggered by the movement of a triggering nose cooperating with a triggering member. In particular, the triggering member may be a ratchet wheel of a column wheel of a chronograph mechanism, the trigger nose being moved by the actuation of a control pusher of the drive hook without exiting of the scope of the invention, as defined by the claims.
