It relates, more particularly, to a timepiece, in particular a timepiece comprising a striking mechanism comprising a striking gear, at least two striking hammers arranged to produce different tone sounds, a lifting of the hours and a first lift of the quarters to actuate one of the hammers, a lift of the minutes and a second lift of the quarters to actuate the other hammer, a part of the hours comprising a toothed sector arranged to cooperate with the ring gear, a rake of the hours arranged to actuate the lifting of the hours and a feeler hours arranged to cooperate with a cam hours, a quarter part comprising a quarter rake having a first set of teeth arranged to actuate the first lift quarters and a second set of teeth to actuate the second quarter lift, and a quarter feeler arranged to cooperate with a quarter cam, and a quarter piece Nutes comprising a minute rake arranged to actuate the lifting of the minutes and a minute feeler arranged to cooperate with a minute cam, said parts of the hours, quarters and minutes being pivotally mounted about a same axis, the quarter piece and the minute piece being kinematically connected by means of a first driving member cooperating with a first toothing.
De telles pièces d'horlogerie sont connues depuis longtemps, en particulier dans le domaine des montres dites compliquées telles que les montres à répétition ou les montres à grande sonnerie. Ces montres possèdent des mécanismes plus ou moins complexes de sonnerie ayant pour but de sonner à la demande ou automatiquement à des intervalles de temps réguliers.Such timepieces have been known for a long time, particularly in the field of so-called complicated watches such as repeating watches or big-bell watches. These watches have more or less complex mechanisms of ringing intended to ring on demand or automatically at regular intervals of time.
Une telle pièce est par exemple décrite dans la demande
Lors du fonctionnement de la sonnerie, les positions initiales respectives de la cheville et de l'ouverture varient en fonction de la position de la pièce des heures et de la pièce des quarts, respectivement, dépendant de l'heure courante. En conséquence, le temps nécessaire pour que la cheville de la pièce des heures vienne en contact avec l'ouverture de la pièce des quarts varie. C'est pourquoi il peut exister un temps mort de durée variable entre la sonnerie des heures et celle des quarts, ou entre celle des heures et celle des minutes lorsqu'il n'y a pas de quart à sonner.When operating the buzzer, the respective initial positions of the peg and the aperture vary depending on the position of the hour room and the quarter room, respectively, depending on the current time. As a result, the time required for the peg of the hour coin to come into contact with the opening of the quarter piece varies. This is why there may be a dead time of varying duration between the hour and the quarter bell, or between the hours and the minutes when there is no quarter to ring.
Un autre type de mécanisme de sonnerie traditionnel, comprenant un rochet des heures est décrit dans le brevet CH 9700. Il est prévu une pièce supplémentaire appelée "échelle" placée entre la pièce des quarts et la pièce des minutes, et présentant une denture intérieure engrenant avec le secteur denté de l'axe de la fusée. Cette pièce permet de régulariser l'intervalle entre la sonnerie des heures et des minutes, le secteur denté de l'axe de la fusée venant engrener par sa première dent avec la dent appropriée de la denture de ladite échelle. Toutefois, un tel mécanisme nécessite une pièce supplémentaire, dans un mécanisme déjà complexe. De plus, cette construction entraîne une rupture d'engrènement, qui pourrait provoquer un passage par des cas critiques tels qu'arc-boutement causant une perte de rendement.Another type of traditional striking mechanism, including a ratchet of the hours is described in the patent CH 9700. There is provided an additional piece called "ladder" placed between the quarter part and the minute piece, and having an internal toothing meshing with the toothed sector of the axis of the rocket. This piece makes it possible to regularize the interval between the hours and minutes striking, the tooth sector of the axis of the rocket meshing with its first tooth with the appropriate tooth of the toothing of said scale. However, such a mechanism requires an additional piece, in an already complex mechanism. In addition, this construction results in a meshing failure, which could cause a passage through critical cases such as over-arching causing a loss of efficiency.
Par ailleurs, les mécanismes d'entraînement de sonnerie sont généralement complexes et prévoient une superposition de différents éléments permettant la préparation à la sonnerie puis la sonnerie en coopération avec le rouage de sonnerie.Furthermore, the ringing drive mechanisms are generally complex and provide for a superposition of different elements for preparing the ring and then the ring in cooperation with the ring gear.

La pièce des heures 2, est de ce fait également libre de pivoter autour de son axe 3, son secteur denté 9 entrainant en rotation le pignon 10 libéré. Sous l'action de son ressort de rappel, la pièce des heures 2 se déplace alors en rotation dans le sens horaire jusqu'à ce que le palpeur des heures 12 atteigne la came des heures 13 positionnée en fonction du temps courant. Le pignon 10 est alors positionné en correspondance sur le secteur denté 9 (à gauche sur la
Lors de la rotation de la pièce des heures 2, le crochet 18 rencontre la butée 22 de sorte que celui-ci pivote et se dégage de la denture 21. La pièce des quarts 4 est ainsi libérée. Sous la poussée de son ressort, la pièce des quarts 4 pivote dans le sens horaire et tombe sur la came des quarts 5 positionnée en fonction du temps courant. De même, lors de la rotation de la pièce des quarts 4, le crochet 30 rencontre la butée 36 de sorte que celui-ci pivote et se dégage de la denture 34. La pièce des minutes 6 est ainsi libérée. Sous la poussée de son ressort, la pièce des minutes 6 pivote dans le sens horaire et tombe sur la came des minutes 27 positionnée en fonction du temps courant. Les pièces ainsi placées, telles que représentées sur les
En référence au mobile d'entrainement de sonnerie 40, l'organe de commande entrainant le rochet de détente 52 est ramené en position de repos par un ressort et bloque le rochet de détente 52.

La roue de sonnerie 41 est entrainée par les autres éléments du rouage de sonnerie dans le sens anti-horaire de sorte que le plateau 44, l'axe 47 et la première extrémité 45a du cliquet 45 avancent également dans le sens anti-horaire. La goupille 50 étant en prise dans le rochet de détente 52 bloqué en rotation par son organe de commande, retient le cliquet 45 de sorte que ledit cliquet 45 bascule autour de l'axe 47 en ramenant le bec 49 vers le pignon 46 jusqu'à ce que le bec 49 coopère avec ledit pignon 46 pour atteindre la position embrayée représentée sur la
En référence au mobile d'entrainement de sonnerie 60, l'organe de commande est ramené en position de repos par un ressort et bloque la denture 65 du râteau 64. Son cliquet de commande 66 retient alors le rochet d'entraînement 68 par la force du ressort 67. Le rochet d'entraînement étant retenu, le tube central 69 et son secteur denté 70 sont également retenus. Le secteur denté 70 du tube central 69 retient alors le secteur denté 82 du plateau 75.With reference to the ringer driving mobile 60, the control member is brought back into the rest position by a spring and blocks the
La roue de sonnerie 61 est entrainée par les autres éléments du rouage de sonnerie dans le sens anti-horaire. Le pivot 77 du plateau 75 étant solidaire de la roue de sonnerie avance également dans le sens anti-horaire. La combinaison du mouvement du pivot 77 du plateau 75 et de la force de son secteur denté 82 provoque un mouvement du cliquet de débrayage 74, son bec 78 basculant en direction de son rochet de débrayage 72. Le bec 78 du cliquet de débrayage 74 atteint le rochet de débrayage 72 et se met alors à le pousser pour atteindre la position embrayée. Dans cette position, le rochet de débrayage 72 étant solidaire de l'axe 15 et donc du pignon 10, ledit pignon 10 est alors relié cinématiquement à la roue de sonnerie 61 par l'intermédiaire du cliquet de débrayage 74, de sorte que le pignon 10 pivote dans le sens anti-horaire.The ringing
Une fois embrayé, c'est le cliquet de débrayage 74 qui, via le secteur denté 82 du plateau 75, entraine le tube central 69 et donc le rochet d'entraînement 68 qui lui est solidaire. Le râteau 64 étant retenu par son organe de commande, il ne pourra pas se mouvoir dans cette direction, son cliquet de commande 66 étant alors agencé pour laisser passer le rochet d'entraînement 68.Once engaged, it is the
Le pignon 10 pivotant dans le sens anti-horaire, entraîne un déplacement en rotation de la pièce des heures 2 dans le sens anti-horaire. Le râteau des heures 11 coopère avec la levée des heures 7a pour soulever le premier marteau en fonction du temps courant. Lorsque les heures ont sonné, la pièce des heures 2 continue sa rotation en entrainant avec elle le crochet 18. Le crochet 18 est agencé de sorte qu'il quitte la butée 22, pivote et entre en contact avec l'une des dents de la denture d'entraînement 21 en fonction de la position de la pièce des quarts 4 dépendante du temps courant.The
L'entraînement de la pièce des quarts par la pièce des heures au moyen d'un crochet et d'une denture prévus respectivement sur l'une ou l'autre de ces pièces selon l'invention permet de supprimer les temps morts. En effet, le crochet 18 et la denture d'entraînement 21 sont dimensionnés et positionnés de sorte que le crochet 18 pénètre directement dans la dent de la denture d'entraînement 21 qui correspond au nombre de quarts à sonner.The training of the quarter part by the hour part by means of a hook and a toothing respectively provided on one or the other of these parts according to the invention makes it possible to eliminate dead times. Indeed, the
Quand les heures ont fini de sonner, le crochet 18 se retrouve toujours au même endroit quel que soit le nombre d'heures sonné. En conséquence, il tombe sur la dent de la pièce des quarts qui s'est positionnée en regard du crochet via le palpeur de quarts en fonction du nombre de quarts à sonner.When the hours have finished ringing, the
La pièce des quarts 4 entrainée par la pièce des heures 2 au moyen du crochet 18 pivote dans le sens anti-horaire, ses dentures 16a, 16b coopérant avec les levées des quarts 7b, 8b pour soulever le premier marteau et le second marteau en fonction du temps courant.The part of the
Lorsque les quarts ont sonné, la pièce des quarts 4 continue sa rotation en entrainant avec elle le crochet 30. Le crochet 30 est agencé de sorte qu'il quitte la butée 36, pivote et entre en contact avec l'une des dents de la denture d'entraînement 34 en fonction de la position de la pièce des minutes 6 dépendante du temps courant.When the quarters have rung, the part of the
La pièce des minutes 6 entrainée par la pièce des quarts 4 au moyen du crochet 30 pivote dans le sens anti-horaire, le râteau des minutes 25 coopérant avec la levées des minutes 8a pour soulever le second marteau en fonction du temps courant.The
En plus de supprimer les temps morts, l'entraînement de la pièce des quarts par la pièce des heures au moyen d'un crochet et d'une denture prévus respectivement sur l'une ou l'autre de ces pièces selon l'invention permet de simplifier le mobile d'entraînement de sonnerie en comparaison avec un mobile d'entraînement de sonnerie traditionnel qui comprend un rochet des heures, un pignon des quarts et son mécanisme d'entraînement, tel qu'un doigt coopérant avec une goupille.In addition to eliminating the dead time, the training of the quarter part by the hour part by means of a hook and a toothing respectively provided on one or other of these parts according to the invention allows to simplify the ringing drive mobile in comparison with a traditional ringing drive mobile which includes a ratchet hours, a quarter gear and its drive mechanism, such as a finger cooperating with a pin.
