Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie mécanique. Elle concerne, plus particulièrement, un mécanisme de sonnerie comportant une source d'énergie pour entraîner des râteaux et un rouage reliant la source d'énergie à un organe régulateur.The present invention relates to the field of mechanical watchmaking. More particularly, it relates to a striking mechanism comprising a power source for driving rakes and a gear train connecting the power source to a regulating member.

Etat de la techniqueState of the art

On connaît ce genre de dispositif, notamment dans les montres appelées grandes sonneries. Ces montres donnent la possibilité de sonner les heures au passage, c'est-à-dire automatiquement tous les quarts et/ou toutes les heures. Il est donc évident que, pour ce faire, le porteur n'a pas besoin d'armer un barillet à chaque sonnerie, comme c'est le cas dans les répétitions à minutes les plus courantes, qui ne sonnent l'heure que sur demande et dans lesquelles un barillet de sonnerie est armé par l'intermédiaire d'une crémaillère lorsque l'utilisateur actionne la targette de commande.We know this kind of device, especially in watches called big ringtones. These watches give the possibility to ring the hours in passing, that is to say automatically every quarter and / or every hour. It is therefore obvious that, to do this, the wearer does not need to arm a barrel at each ring, as is the case in the most common minute repeaters, which only sound the time on request and in which a ringer barrel is armed via a rack when the user actuates the control bolt.

Les grandes sonneries sont donc équipées d'un rouage complet pour l'entraînement des pièces de sonnerie. Ce rouage relie donc un barillet de sonnerie muni de son propre système de remontage à un organe régulateur. Le barillet fournit de l'énergie aux pièces de sonnerie par l'intermédiaire d'un organe de commande et de distribution disposé dans le rouage, éventuellement coaxialement au barillet. L'organe de commande et de distribution comprend un empilement de plusieurs roues, libres ou solidaires en rotation les unes par rapport aux autres. Sans expliquer en détail ce dispositif qui est complètement décrit dans l'ouvrage " Les montres compliquées" de F. Lecoultre, aux Editions Horlogères, pages 182-205 , on peut résumer que des cliquets agencés dans cet organe et commandés par des bascules permettent de gérer les différentes étapes du déroulement de la sonnerie.The big ringtones are therefore equipped with a complete gear train for driving the ringing parts. This wheel thus connects a barrel of ringing with its own winding system to a regulating organ. The barrel provides energy to the ringing parts through a control and distribution member disposed in the train, possibly coaxially with the barrel. The control and distribution member comprises a stack of several wheels, free or fixed in rotation relative to each other. Without explaining in detail this device which is completely described in the book " Complicated watches "by F. Lecoultre, at Horloger's Editions, pages 182-205 it can be summarized that pawls arranged in this organ and controlled by rockers to manage the various stages of the course of the ring.

La présente invention a pour but de proposer une alternative avantageuse aux dispositifs de l'état de la technique.The object of the present invention is to propose an advantageous alternative to the devices of the state of the art.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, dans un mécanisme de sonnerie selon l'invention concerne, les pièces de sonnerie sont reliées cinématiquement à la source d'énergie par l'intermédiaire d'un différentiel disposé dans le rouage.More precisely, in a striking mechanism according to the invention, the striking pieces are kinematically connected to the energy source via a differential disposed in the gear train.

Avantageusement, ce différentiel comprend une première roue d'entrée reliée cinématiquement au rouage et une deuxième roue d'entrée reliée à un organe de commande et une roue de sortie reliée aux pièces de sonnerie.Advantageously, this differential comprises a first input wheel kinematically connected to the wheel and a second input wheel connected to a control member and an output wheel connected to the ringing parts.

L'organe de commande est agencé de manière à ce que le différentiel puisse occuper:

  • une première configuration dans laquelle la première roue d'entrée est bloquée en rotation et la deuxième roue d'entrée est libre en rotation, la roue de sortie étant libre en rotation,

  • une troisième configuration dans laquelle la première et la deuxième roues d'entrées sont bloquées en rotation, la roue de sortie étant elle aussi bloquée en rotation.
The control member is arranged in such a way that the differential can occupy:
  • a first configuration in which the first input wheel is locked in rotation and the second input wheel is free to rotate, the output wheel being free to rotate,
  • a second configuration in which the first input wheel is free to rotate, the second input wheel is locked in rotation, the output wheel then being free to be driven via the first input wheel, and
  • a third configuration in which the first and second input wheels are locked in rotation, the output wheel is also locked in rotation.

  • une première roue solaire constituant la première entrée du différentiel et reliée cinématiquement avec une roue du rouage,
  • au moins un satellite inférieur engrenant avec la première roue solaire,
  • une roue porte-satellites libre en rotation et coaxiale avec la roue solaire, constituant la deuxième entrée du différentiel, ledit satellite inférieur étant monté à rotation sur un premier niveau de la roue porte-satellites,
  • au moins un satellite supérieur monté à rotation sur un deuxième niveau de la roue porte-satellites, monté coaxial et solidaire en rotation avec le satellite inférieur,
  • une roue solaire supérieure, engrenant avec le satellite supérieur et constituant la sortie du différentiel.
In a preferred embodiment, the differential comprises:

  • at least one lower satellite meshing with the first sun gear,
  • a planet carrier wheel free in rotation and coaxial with the sun gear, constituting the second input of the differential, said lower satellite being rotatably mounted on a first level of the planet carrier wheel,
  • at least one upper satellite rotatably mounted on a second level of the planet carrier wheel, coaxially mounted and fixed in rotation with the lower satellite,
  • an upper sun wheel, meshing with the upper satellite and constituting the output of the differential.

De préférence, l'organe de commande est un arbre à cames comprenant une première came pour bloquer ou laisser libre en rotation la première roue d'entrée, une deuxième came pour bloquer ou laisser libre en rotation la deuxième roue d'entrée et au moins un mobile d'entraînement pour le pivotement de l'arbre.Preferably, the control member is a camshaft comprising a first cam for blocking or free rotation of the first input wheel, a second cam for locking or free rotation of the second input wheel and at least a driving wheel for pivoting the shaft.

Pour offrir à l'utilisateur la possibilité de désactiver la sonnerie, le mécanisme peut comprendre un dispositif de silencieux muni d'un verrou susceptible d'évoluer entre une première et une deuxième positions, dans laquelle il coopère avec le mobile d'entraînement pour bloquer l'organe de commande. Ce verrou peut être déplace par des moyens de commande manuel, actionnés par le porteur, ou par des moyens de commande automatique, par exemple pour empêcher une sonnerie au passage de se déclencher en dessous d'une certaine réserve de marche.In order to offer the user the possibility of deactivating the buzzer, the mechanism may comprise a silencer device provided with a latch capable of changing between a first and a second position, in which it co-operates with the driving wheel to block the control organ. This lock can be moved by manual control means, actuated by the carrier, or by automatic control means, for example to prevent a ringing at the passage to be triggered below a certain power reserve.

  • a series of snails 16 driven by the basic movement of the timepiece in which the mechanism is mounted, and providing information on current time, and
  • rakes 18 arranged to cooperate with these snails 16 to operate hammers striking stamps to produce a ring identifying the current time.

Ce mécanisme n'étant pas directement i'objet de i'invention, il ne sera pas décrit en détail. On pourra se référer à la demande EP 06121650.3 qui l'explique complètement. Les râteaux pourraient également faire partie d'un mécanisme plus conventionnel tel que décrit dans l'ouvrage précité ou encore 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 .Since this mechanism is not directly the subject of the invention, it will not be described in detail. We can refer to the request EP 06121650.3 who explains it completely. The rakes could also be part of a more conventional mechanism as described in the aforementioned work or in the book " Theory of Watchmaking "by Reymondin et al, Federation of Technical Schools, 1998, ISBN 2-940025-10-X, pages 219-224 .

Particulièrement à l'invention, un différentiel 20 relie cinématiquement le rouage 12 aux râteaux afin qu'ils soient entraînés au cours de la sonnerie par le barillet 10.Particularly to the invention, a differential 20 kinematically connects the gear 12 to the rakes so that they are driven during the ring by the barrel 10.

Un exemple de différentiel 20 particulièrement adapté à l'invention est représenté sur la figure 2. Sur un arbre d'axe A-A, il comprend une première roue solaire 22 constituant une première entrée du différentiel et reliée cinématiquement avec une roue du rouage 12. Selon l'exemple, le différentiel 20 est coaxial et solidaire avec cette roue du rouage 12. Cette roue solaire 22 engrène avec au moins un, typiquement trois, satellites inférieurs 24 montés à rotation sur un premier niveau d'une roue porte-satellites 26 munie d'une denture périphérique. Cette dernière constitue une deuxième entrée du différentiel. Elle est libre en rotation et coaxiale avec la roue solaire 22. Les trois satellites inférieurs 24 sont chacun montés coaxiaux et solidaires en rotation avec au moins un, typiquement trois, satellites supérieurs 28 montés à rotation sur un deuxième niveau de la roue porte-satellites 26. Les satellites supérieurs 28 engrènent avec une roue solaire supérieure 30, coaxiale et solidaire en rotation d'un renvoi 32. Cette roue solaire supérieure 30 constitue la sortie du différentiel.An example of a differential 20 particularly adapted to the invention is shown in FIG. 2. On a shaft AA axis, it comprises a first sun gear 22 constituting a first input of the differential and kinematically connected with a wheel of the gear 12. According to the example, the differential 20 is coaxial and integral with this wheel of the gear 12. This sun gear 22 meshes with at least one, typically three, lower satellites 24 rotatably mounted on a first level of a planet carrier wheel 26 provided with of a peripheral toothing. The latter constitutes a second differential input. It is free in rotation and coaxial with the sun gear 22. The three lower satellites 24 are each mounted coaxial and integral in rotation with at least one, typically three, upper satellites 28 rotatably mounted on a second level of the planet carrier wheel. 26. The upper satellites 28 meshes with an upper solar wheel 30, coaxial and rotationally integral with a reference 32. This upper sun gear 30 is the output of the differential.

Comme on peut le voir sur la figure 1, ce renvoi 32 est en prise avec un secteur denté 34 d'un palpeur des heures, destiné à coopérer avec le limaçon des heures. Un rochet des heures 36, destiné à actionner une levée pour sonner les heures, est également solidaire en rotation du renvoi 32. Le rochet des heures 36 est donc directement relié cinématiquement au palpeur des heures.As can be seen in Figure 1, this reference 32 is engaged with a toothed sector 34 of an hours probe, intended to cooperate with the snail hours. A ratchet of 36 hours, intended to actuate a lift to ring the hours, is also integral in rotation of the reference 32. The hour ratchet 36 is therefore directly kinematically connected to the feeler hours.

Ainsi, il apparaît que le différentiel peut occuper trois configurations utiles différentes en agissant sur les deux entrées.

  • Une première configuration dans laquelle la roue porte-satellites 26 est libre en rotation et dans laquelle la roue solaire inférieure 22 est bloquée : la roue solaire supérieure 30 et les éléments qui lui sont solidaires sont libres de tourner. Les satellites 24 et 28 tournent en effet autour de l'axe A-A du différentiel 20, car les satellites inférieurs 24 roulent sur la roue solaire inférieure 22 qui est bloquée.
  • Une deuxième configuration dans laquelle la roue porte-satellites 26 est bloquée en rotation et la roue solaire inférieure 22 est libre d'être entraînée par le rouage 12 : la roue solaire supérieure 30 est alors libre d'être entraînée par le rouage. En effet, dans ce cas, les satellites se comportent comme un simple renvoi vertical et transmettent la rotation de la roue solaire inférieure 22 à la roue solaire supérieure 30.
  • Une troisième configuration dans laquelle la roue porte-satellites 26 et la roue solaire inférieure 22 sont bloquées en rotation : la roue solaire supérieure 30 est elle aussi bloquée, de ce fait, en rotation. Les satellites 24 et 28 ne peuvent, dans ce cas, ni tourner sur eux-mêmes, ni tourner autour de l'axe A-A du différentiel.
Thus, it appears that the differential can occupy three different useful configurations by acting on the two inputs.
  • A first configuration in which the planet carrier wheel 26 is free to rotate and in which the lower sun gear 22 is locked: the upper sun gear 30 and the elements which are integral therewith are free to rotate. The satellites 24 and 28 rotate around the axis AA of the differential 20 because the lower satellites 24 roll on the lower sun gear 22 which is blocked.
  • A second configuration in which the planet wheel 26 is locked in rotation and the lower sun gear 22 is free to be driven by the gear 12: the upper sun gear 30 is then free to be driven by the gear train. Indeed, in this case, the satellites behave as a simple vertical reference and transmit the rotation of the lower sun gear 22 to the upper sun gear 30.
  • A third configuration in which the planet wheel 26 and the lower sun gear 22 are locked in rotation: the upper sun gear 30 is also locked, thereby, in rotation. The satellites 24 and 28 can not, in this case, turn on themselves or turn around the axis AA of the differential.

On comprend donc que, dans la première configuration ci-dessus, les râteaux 18 liés cinématiquement au palpeur des heures, peuvent bouger indépendamment du rouage 12 et du barillet 10. Cette configuration est celle qui est utilisée, lors du déclenchement de la sonnerie, pour permettre aux palpeurs des différents râteaux, de tomber sur leur limaçon respectif pour prendre une information relative au temps courant. La deuxième configuration permet de relier cinématiquement le barillet 10 aux râteaux 18. C'est donc celle qui est utilisée au cours du déroulement de la sonnerie pour que les râteaux se déplacent relativement à leur levée pour actionner les marteaux. Enfin, la troisième configuration correspond à la situation dans laquelle les râteaux 18 sont arrêtés et maintenus au repos.It is thus clear that, in the first configuration above, the rakes 18 kinematically connected to the hour sensor, can move independently of the gear train 12 and the cylinder 10. This configuration is the one that is used, when the bell is triggered, for allow the feelers of the different rakes, to fall on their respective snail to take information relative to the current time. The second configuration makes it possible to kinematically connect the barrel 10 to the rakes 18. This is the one that is used during the course of the ringing so that the rakes move relative to their lifting to operate the hammers. Finally, the third configuration corresponds to the situation in which the rakes 18 are stopped and kept at rest.

Comme on le comprendra mieux dans la suite de la description, le blocage de la roue solaire inférieure 22 se fait, selon le mode de réalisation préféré représenté sur les dessins, en bloquant le dévidement du barillet de sonnerie 10. Avantageusement, ce blocage est obtenu par un élément de butée 38 agencé de manière à évoluer entre une première et une deuxième positions extrêmes, l'élément de butée 38 croisant, dans l'une de ces positions extrêmes, la course d'une goupille 40 montée en saillie sur l'organe régulateur 14. C'est en effet à cet endroit du rouage que le couple est le moins important et que le blocage peut se faire avec une sécurité optimale. Ces éléments sont visibles sur la figure 6 et leur actionnement sera décrit ci-après.As will be better understood in the following description, the blocking of the lower sun gear 22 is, according to the preferred embodiment shown in the drawings, by blocking the unwinding of the ringer barrel 10. Advantageously, this lock is obtained by a stop element 38 arranged to move between a first and a second extreme position, the stop element 38 crossing, in one of these extreme positions, the stroke of a pin 40 projecting on the This is where the torque is the least important and the locking can be done with optimum safety. These elements are visible in Figure 6 and their operation will be described below.

On peut voir sur la figure 3 que le blocage de la roue porte-satellites 26 se fait directement par l'intermédiaire d'un verrou 42, ayant la forme d'un crochet 42a disposé sur une bascule 42b et susceptible d'évoluer entre une première et une deuxième positions extrêmes, le crochet 42a coopérant avec la denture de la roue porte-satellites 26 lorsqu'il se trouve dans l'une de ces positions extrêmes.It can be seen in FIG. 3 that the locking of the planet carrier wheel 26 is done directly via a latch 42, having the shape of a hook 42a disposed on a latch 42b and capable of changing between a first and second extreme positions, the hook 42a cooperating with the toothing of the planet carrier wheel 26 when it is in one of these extreme positions.

Nous allons maintenant examiner la manière dont l'élément de butée 38, d'une part, et le verrou 42, d'autre part, sont commandés afin qu'ils évoluent chacun entre leur première et deuxième positions extrêmes, de manière coordonnée.We will now examine how the stop element 38, on the one hand, and the latch 42, on the other hand, are controlled so that they each move between their first and second extreme positions, in a coordinated manner.

Un arbre à cames 50, particulièrement visible sur la figure 3, est monté pivotant dans le bâti et comporte une première came 52 destinée à commander le blocage de la roue solaire inférieure 22 et une deuxième came 54 commandant le blocage de la roue porte-satellites 26.A camshaft 50, particularly visible in FIG. 3, is pivotally mounted in the frame and comprises a first cam 52 intended to control the locking of the lower sun gear 22 and a second cam 54 controlling the locking of the planet wheel 26.

Les cames et les étoiles sont représentées individuellement à la figure 4. L'arbre à cames 50 est positionné par une première étoile 56 comportant un premier niveau 56a (figure 4a) muni de douze dents coopérant avec un sautoir 58 et un deuxième niveau 56b (figure 4b) ne comportant que quatre dents, régulièrement réparties sur un taillage de douze dents et superposées avec les dents du premier niveau. Cette étoile 56 remplit également la fonction de mobile d'entraînement de i'arbre 50, comme il sera décrit en détail par la suite.The cams and the stars are shown individually in FIG. 4. The camshaft 50 is positioned by a first star 56 comprising a first level 56a (FIG. 4a) provided with twelve teeth cooperating with a jumper 58 and a second level 56b ( Figure 4b) having only four teeth, regularly distributed on a cut of twelve teeth and superimposed with the teeth of the first level. This star 56 also performs the function of training drive of the shaft 50, as will be described in detail later.

Le fonctionnement du différentiel faisant intervenir trois configurations, l'étoile de positionnement 56 est nombrée selon un multiple de trois, douze présentant un pas angulaire entre deux positions consécutives avantageux par rapport à la taille de ces pièces et à l'espace disponible.The operation of the differential involving three configurations, the positioning star 56 is numbered in a multiple of three, twelve having an angular pitch between two consecutive advantageous positions with respect to the size of these parts and the available space.

La première came 52 représentée à la figure 4c, présente une succession de parties saillantes et de parties creuses. Comme mentionné ci-dessus et illustré par la figure 6, le blocage de la roue solaire inférieure 22 se fait au niveau de l'organe régulateur 14. L'élément de butée 38 peut être disposé à l'extrémité d'une double bascule 58, comprenant deux bascules 58a et 58b articulées l'une avec l'autre par un tenon 58c solidaire de l'une d'elles 58a et coopérant avec un logement 58d ménagé dans l'autre 58b. Un ressort 60 est disposé de manière à appuyer l'extrémité de la bascule 58a contre la première came 52. Les points de pivot de la double bascule 58 sont agencés, dans l'exemple, de manière à ce que, lorsque la bascule 58a appuie contre une partie saillante de la came 52, l'élément de butée 38 coopère avec l'organe régulateur 14, ce qui bloque la roue solaire inférieure 22. A l'inverse, lorsque la came 52 présente une partie creuse à la bascule 58a, la roue solaire inférieure 22 est libre. Ainsi, pour un cycle de sonnerie, la came 52 est dotée d'une succession d'une partie saillante, d'une partie creuse et d'une partie saillante, cette série étant répétée quatre fois selon l'exemple d'un arbre à cames 50 à douze positions.The first cam 52 shown in Figure 4c has a succession of projections and hollow portions. As mentioned above and illustrated in FIG. 6, the blocking of the lower sun wheel 22 is at the level of the regulating member 14. The stop element 38 can be arranged at the end of a double rocker 58 , comprising two rockers 58a and 58b articulated with each other by a pin 58c integral with one of them 58a and cooperating with a housing 58d formed in the other 58b. A spring 60 is arranged to support the end of the rocker 58a against the first cam 52. The pivot points of the double rocker 58 are arranged, in the example, so that when the rocker 58a supports against a protruding part of the cam 52, the stop element 38 cooperates with the regulating member 14, which blocks the lower sun gear 22. Conversely, when the cam 52 has a hollow portion at the rocker 58a, the lower sun wheel 22 is free. Thus, for a ringing cycle, the cam 52 is provided with a succession of a protruding part, a hollow part and a protruding part, this series being repeated four times according to the example of a shaft. cams 50 to twelve positions.

La deuxième came 54 (figure 4d) présente également une succession de parties saillantes et de parties creuses. Un ressort 62 est agencé de manière à appuyer l'extrémité de la bascule 42 ne portant pas le crochet 42a contre la came 54. Dans l'exemple, le point de pivot de la bascule 42 est agencé de manière à ce que, lorsque la came 54 présente une partie saillante à la bascule 42, le crochet 42a est en dehors de la denture de la roue porte-satellites 26 qui est donc libre en rotation. A l'inverse, lorsque la bascule 42 appuie contre un creux de la came, la roue porte-satellites 26 est bloquée. Ainsi, pour un cycle de sonnerie, la came 54 est dotée d'une succession d'une partie saillante et de deux parties creuses, cette série étant répétée quatre fois selon l'exemple d'un arbre à cames à douze positions.The second cam 54 (Figure 4d) also has a succession of projecting parts and hollow parts. A spring 62 is arranged to support the end of the latch 42 not carrying the hook 42a against the cam 54. In the example, the pivot point of the latch 42 is arranged so that when the Cam 54 has a protruding portion at the latch 42, the hook 42a is outside the toothing of the planet carrier wheel 26 which is free to rotate. Conversely, when the rocker 42 presses against a hollow of the cam, the planet wheel 26 is blocked. Thus, for a ringing cycle, the cam 54 is provided with a succession of a protruding part and two hollow parts, this series being repeated four times according to the example of a twelve-position camshaft.

L'homme du métier saura coordonner les deux cames de manière à avoir les positions suivantes: Configuration Première came Roue solaire inférieure Deuxième came Roue porte-satellites 1 Saillie Bloquée Saillie Libre 2 Creux Libre Creux Bloquée 3 Saillie Bloquée Creux Bloquée Those skilled in the art will know how to coordinate the two cams so as to have the following positions: Configuration First cam Lower solar wheel Second cam Satellite carrier wheel 1 projection blocked projection Free 2 Hollow Free Hollow blocked 3 projection blocked Hollow blocked

Afin d'expliquer comment l'arbre à cames 50 est entraîné pour passer d'une configuration à une autre, on partira de la configuration 3 dans laquelle les râteaux 18 sont au repos. Le passage à la configuration 1 se fait lors du déclenchement d'une sonnerie, c'est-à-dire soit au passage, soit à la demande.In order to explain how the camshaft 50 is driven to move from one configuration to another, one will start from the configuration 3 in which the rakes 18 are at rest. The transition to configuration 1 is done when triggering a ring, that is to say, either on the way or on demand.

Pour le déclenchement au passage, on pourra se référer à la figure 3 qui montre un doigt souple 70 destiné à coopérer avec le deuxième niveau 56b de l'étoile 56 et entraîné en rotation par le mouvement de base de la pièce d'horlogerie. Par exemple, le doigt 70 effectue un mouvement de va-et-vient sous l'action d'une douille 72 dont le pourtour définit une sorte de colimaçon et comporte un plan incliné 72a. Le doigt 70 est maintenu appuyé contre la came par un ressort 74 au niveau d'un ergot 70a dont il est muni. La douille est entraînée, dans le sens antihoraire par rapport à la figure 3, par la roue des minutes du mouvement de base, à raison d'un tour par heure, ce qui fait pivoter le doigt 70 dans le sens antihoraire et charge le ressort 74. Toutes les heures, au passage de l'heure, l'ergot passe le plan incliné et le doigt 70, sous l'effet du ressort 74, pivote dans le sens horaire et entraîne l'étoile 56 d'un pas, faisant ainsi passer le différentiel à la configuration 1.For triggering the passage, we can refer to Figure 3 which shows a flexible finger 70 for cooperating with the second level 56b of the star 56 and rotated by the base movement of the timepiece. For example, the finger 70 moves back and forth under the action of a sleeve 72 whose periphery defines a kind of spiral and has an inclined plane 72a. The finger 70 is held against the cam by a spring 74 at a lug 70a which it is provided. The bushing is driven, counterclockwise with respect to FIG. 3, by the minute wheel of the basic movement, at a rate of one revolution per hour, which makes the finger 70 turn counterclockwise and load the spring 74. Every hour, at the passage of time, the lug passes the inclined plane and the finger 70, under the effect of the spring 74, pivots clockwise and drives the star 56 a step, making thus pass the differential to configuration 1.

La douille 72 pourrait aussi comporter une pluralité de plans inclinés de manière à actionner le doigt tous les quarts d'heure, pour sonner les quarts, un isolateur pouvant alors être prévu s'il est souhaité que les heures ne soient pas sonnées lors de la sonnerie des quarts.The sleeve 72 could also include a plurality of inclined planes so as to actuate the finger every quarter of an hour, to ring quarters, an isolator can then be provided if it is desired that the hours are not ringed during the quarter ringing.

Pour le déclenchement manuel, on se référera à la figure 5. Il est proposé que l'utilisateur actionne une targette 76 solidaire d'une crémaillère 78, à l'instar d'une répétition à minutes conventionnelle. La crémaillère 78 engrène avec une denture extérieure d'un anneau 80, coaxial avec le barillet de sonnerie 10. Cet anneau 80 est relié à l'arbre du barillet 10 par un ressort radial 82 possédant un moyeu 82a monté à carré sur l'arbre et typiquement deux lames élastiques 82b, exerçant une pression radiale vers i'extérieure de la roue et se terminant par une portion dentée coopérant avec une denture intérieure que comporte l'anneau 80. Le ressort 82 et la denture intérieure de l'anneau 80 sont agencés de manière à former un encliquetage entre l'arbre du barillet 10 et la crémaillère 78. Ainsi, le pivotement de l'anneau 80 dans un sens entraîne l'arbre de barillet en rotation, mais ni le pivotement de l'arbre du barillet dans l'autre sens, par exemple lors du démontage du mouvement, ni l'entraînement de l'arbre lors du remontage manuel du barillet de sonnerie ne provoque de déplacement de la targette 76.For manual triggering, reference is made to FIG. 5. It is proposed that the user actuate a bolt 76 secured to a rack 78, like a conventional minute repeater. The rack 78 meshes with an external toothing of a ring 80, coaxial with the striking barrel 10. This ring 80 is connected to the shaft of the barrel 10 by a radial spring 82 having a hub 82a mounted square on the shaft and typically two blades resilient 82b, exerting a radial pressure towards the outside of the wheel and ending in a toothed portion cooperating with an internal toothing that includes the ring 80. The spring 82 and the internal toothing of the ring 80 are arranged in such a way as to forming a snap between the shaft of the barrel 10 and the rack 78. Thus, the pivoting of the ring 80 in one direction drives the barrel shaft in rotation, but neither the pivoting of the barrel shaft in the other sense, for example during disassembly of the movement, nor the drive of the shaft during the manual winding of the barrel of ringing causes displacement of the bolt 76.

La denture extérieure de l'anneau 80 transmet le mouvement de la targette à une roue 84 avec laquelle elle engrène. Cette roue 84 est munie d'un système de rappel 86, par exemple un ressort spiral, permettant le retour de la targette 76 à sa position de repos puisque le système d'encliquetage mentionné ci-dessus ne permet pas que ce retour soit assuré par i'énergie fournie par le barillet 10, comme c'est le cas dans les répétitions classiques. La roue 84 porte également un bras 88 monté sur son axe et se terminant par une zone d'appui 88a destinée à coopérer avec une deuxième étoile 90 (figure 4e), jouant également le rôle d'élément d'entraînement de l'arbre 50, pour faire avancer l'arbre à came 50 d'un pas et faire passer le différentiel à la configuration 1. Cette étoile 90 est taillée sur le nombre douze mais ne comporte que quatre dents, c'est-à-dire une par cycle de sonnerie. Elle est également bien visible sur la figure 7.The outer toothing of the ring 80 transmits the movement of the bolt to a wheel 84 with which it meshes. This wheel 84 is provided with a return system 86, for example a spiral spring, allowing the return of the bolt 76 to its rest position since the latching system mentioned above does not allow this return to be ensured by the energy provided by the barrel 10, as is the case in conventional repetitions. The wheel 84 also carries an arm 88 mounted on its axis and ending with a bearing zone 88a intended to cooperate with a second star 90 (FIG. 4e), also acting as a drive element for the shaft 50. , to advance the camshaft 50 one step and pass the differential to the configuration 1. This star 90 is cut on the number twelve but has only four teeth, that is to say one per cycle of ringtone. It is also clearly visible in FIG.

Ce dispositif d'enclenchement manuel fait l'objet d'une demande de brevet ayant la même date de dépôt que la présente demande et dans laquelle il est décrit plus en détail.This manual engagement device is the subject of a patent application having the same filing date as the present application and in which it is described in more detail.

Dans une version simplifiée, on pourrait prévoir qu'une simple bascule entraînée par un poussoir disposé dans la carrure de la montre, entraîne l'étoile 90 d'un pas, sans réarmer le barillet.In a simplified version, it could be provided that a simple rocker driven by a pusher disposed in the middle part of the watch, drives the star 90 by one step, without rearming the barrel.

Pour le passage de l'arbre à cames à la configuration 2, les dents de l'étoile 90 sont susceptibles de croiser le chemin d'une roue de transmission 92, mise en rotation en permanence par le rouage principal du mouvement. Typiquement, cette roue est entraînée par la roue de petite moyenne à raison d'un tour en trente secondes environ. L'homme du métier saura déterminer la forme des dents de l'étoile 90 et de la roue de transmission 92 pour assurer une bonne transmission du couple.For the passage from the camshaft to the configuration 2, the teeth of the star 90 are likely to cross the path of a transmission wheel 92, rotated permanently by the main wheel of the movement. Typically, this wheel is driven by the wheel of small average at the rate of one turn in thirty seconds approximately. The skilled person will determine the shape of the teeth of the star 90 and the transmission wheel 92 to ensure good torque transmission.

Plus particulièrement, les dents de l'étoile 90 sont disposées sur l'arbre à cames de manière à croiser le chemin de la roue de transmission 92 lorsque le différentiel est dans sa première configuration. L'arbre à cames 50 est donc entraîné lentement d'un pas et fait passer le différentiel 20 à la configuration 2.More particularly, the teeth of the star 90 are disposed on the camshaft so as to cross the path of the transmission wheel 92 when the differential is in its first configuration. The camshaft 50 is thus driven slowly by one step and passes the differential 20 to the configuration 2.

On rappellera que, dans la configuration 2, les râteaux 18 sont reliés cinématiquement au barillet 10 de manière à permettre le déroulement de la sonnerie en tant que tel. L'arbre 50 ne doit donc avancer d'un pas supplémentaire qu'à la fin de la sonnerie.It will be recalled that, in configuration 2, the rakes 18 are kinematically connected to the barrel 10 so as to allow the ringing to proceed as such. The shaft 50 must therefore move one step further than the end of the ring.

Pour ce faire, un des râteaux 18, de préférence le râteau des minutes 18a, car c'est lui qui intervient en dernier dans la sonnerie, ou une pièce qui lui est liée cinématiquement, permet le déplacement d'un élément de transmission à la fin de la sonnerie. En référence à la figure 5, cet élément peut être un doigt 94 agencé de manière à coopérer avec la première étoile 56 pour faire avancer l'arbre à cames 50 d'un pas. Dans ce cas, le râteau des minutes 18a porte une goupille 96 destinée à entraîner le doigt 94. Avantageusement, ce doigt 94 se situe à l'extrémité d'une portion élastique d'une bascule 98, ce qui améliore la sécurité du dispositif. Un ressort 99 maintient la bascule 98 en appui contre la goupille 96. Ainsi, en fin de sonnerie, l'arbre à cames 50 avance d'un pas, ce qui permet au différentiel de passer à la configuration 3. Un nouveau cycle de sonnerie peut démarrer.To do this, one of the rakes 18, preferably the minute rake 18a, because it is he who intervenes last in the ring, or a piece which is kinematically related thereto, allows the displacement of a transmission element to the end of the ring. Referring to Figure 5, this element may be a finger 94 arranged to cooperate with the first star 56 to advance the camshaft 50 by one step. In this case, the rake minutes 18a carries a pin 96 for driving the finger 94. Advantageously, the finger 94 is located at the end of an elastic portion of a flip-flop 98, which improves the safety of the device. A spring 99 holds the rocker 98 against the pin 96. Thus, at the end of the ring, the camshaft 50 advances by one step, which allows the differential to move to the configuration 3. A new ringing cycle can start.

Pour résumer, lorsque la sonnerie est au repos, le différentiel 20 est dans sa configuration 3, le barillet 10 étant verrouillé, et les râteaux 18 étant ainsi maintenues en position. Lors du déclenchement de la sonnerie, soit manuel, soit au passage, l'arbre à cames 50 est entraîné d'un pas, ce qui permet d'amener le différentiel 20 dans sa configuration 1. Les râteaux sont alors débrayés du rouage de sonnerie 12 et ils peuvent alors tomber librement, sous l'effet de leur ressort respectif, sur leur limaçon pour prendre une information relative au temps courant. Cette étape est très rapide et se fait pendant que la roue de transmission 92 entraîne la deuxième étoile 90 et fait passer le différentiel 20 dans sa configuration 2. Les râteaux sont alors reliés cinématiquement au barillet 10 qui est libéré. Le sens de déplacement des râteaux s'inverse alors et leur secteur denté actionne les levées et les marteaux pour produire la sonnerie. Enfin, à la fin de la sonnerie, la goupille 96 provoque l'avance d'un pas supplémentaire de l'arbre à cames 50 de manière à ce que le mécanisme se trouve à nouveau dans sa position de repos.To summarize, when the ring is at rest, the differential 20 is in its configuration 3, the barrel 10 being locked, and the rakes 18 thus being held in position. When triggering the ring, either manually or in passing, the camshaft 50 is driven one step, which allows to bring the differential 20 in its configuration 1. The rakes are then disengaged from the ring gear 12 and then they can freely fall, under the effect of their respective spring, on their snail to take a information relating to the current time. This step is very fast and is done while the transmission wheel 92 drives the second star 90 and passes the differential 20 in its configuration 2. The rakes are then kinematically connected to the barrel 10 which is released. The direction of movement of the rakes is then reversed and their toothed sector activates the levies and hammers to produce the ring. Finally, at the end of the ring, the pin 96 causes the advance of an additional step of the camshaft 50 so that the mechanism is again in its rest position.

On notera que, grâce au fait que le doigt 70 coopère avec le deuxième niveau 56b de l'étoile 56, si un déclenchement au passage intervient au cours du déroulement d'une sonnerie qui vient d'être déclenchée manuellement, alors le doigt 70 ne va trouver sur son chemin qu'un espace dépourvu de dent et ne butera pas contre l'arbre à cames. Cette sécurité est particulièrement avantageuse car tenter de déclencher une sonnerie au passage alors qu'une sonnerie est déjà en cours provoquerait de graves dommages au mécanisme.Note that, because the finger 70 cooperates with the second level 56b of the star 56, if a trip trigger occurs during the course of a ring that has just been triggered manually, then the finger 70 does not will find on its way that a space devoid of teeth and will not abut against the camshaft. This security is particularly advantageous because trying to trigger a ringing in passing while a ringing is already in progress would cause serious damage to the mechanism.

Le même effet est obtenu pour le déclenchement manuel grâce à la structure de l'étoile 90. Si un déclenchement manuel intervient au cours du déroulement d'une sonnerie qui vient d'être déclenchée manuellement ou au passage, alors le bras 88 ne va trouver sur son chemin qu'un espace dépourvu de dent et ne butera pas contre l'arbre 50. Combiné au système de remontage manuel décrit ci-dessus, il est même possible de remonter le barillet 10 uniquement par la targette, soit pendant une sonnerie, soit en ajustant la course de la targette de manière à ne pas déclencher de sonnerie.The same effect is obtained for manual triggering thanks to the structure of the star 90. If a manual trigger occurs during the course of a ring that has just been triggered manually or by the way, then the arm 88 will not find on its way a toothless space and will not abut against the shaft 50. Combined with the manual winding system described above, it is even possible to refit the barrel 10 only by the bolt, or during a ring, or by adjusting the stroke of the bolt so as not to sound a bell.

Le mécanisme selon l'invention peut, en outre, comporter un dispositif de silencieux 100 représenté sur la figure 7 et permettant à l'utilisateur d'empêcher le déclenchement au passage de la sonnerie. A cet effet, un poussoir ou un correcteur non représenté est disposé dans la carrure de la montre et fait évoluer une coulisse 102 entre une première position de repos et une deuxième position. Cette coulisse 102 est montée mobile en translation sur la platine du mécanisme de sonnerie et comporte, dans ce but, deux oblongs 102a dans lesquels passent des vis à portée.The mechanism according to the invention may further comprise a silencer device 100 shown in Figure 7 and allowing the user to prevent the triggering of the ringing. For this purpose, a pusher or corrector not shown is arranged in the middle part of the watch and makes a slide 102 evolve between a first rest position and a second position. This slide 102 is movably mounted in translation on the plate of the striking mechanism and comprises, for this purpose, two oblongs 102a in which pass screws in range.

La coulisse 102 coopère avec un tenon 104 disposé sur une bascule 106. Un verrou 108 est monté pivotant, coaxial à la bascule 106. Le verrou 108 est agencé de manière à pouvoir évoluer entre une première position de repos et une deuxième position dans laquelle il coopère avec la deuxième étoile 90, pour empêcher la rotation de l'arbre 50. Plus particulièrement, le verrou 108 présente une échancrure qui épouse sensiblement la circonférence de l'arbre à cames. L'échancrure définit un doigt 108a susceptible d'interagir avec les dents de l'étoile 90. Ces dents sont conformées de manière à venir s'appuyer sensiblement orthogonalement sur le doigt 108a, pour obtenir un blocage efficace.The slide 102 cooperates with a pin 104 disposed on a rocker 106. A latch 108 is pivotally mounted, coaxial with the rocker 106. The latch 108 is arranged to be able to move between a first rest position and a second position in which it cooperates with the second star 90, to prevent the rotation of the shaft 50. More particularly, the lock 108 has a notch which substantially matches the circumference of the camshaft. The notch defines a finger 108a capable of interacting with the teeth of the star 90. These teeth are shaped so as to bear substantially orthogonally on the finger 108a, to obtain an effective locking.

Le verrou 108 est doté d'un tigeron 110 susceptible de coopérer avec une surface d'appui 106a que présente la bascule 106. Un premier ressort 112 maintient le tigeron 110 en appui contre la surface 106a. La force exercée par ce ressort 112 sur le verrou tend à l'éloigner de l'arbre à cames 50 et à le ramener à sa première position. Un deuxième ressort 114 est agencé de manière à plaquer la bascule 106 contre la coulisse 102.The lock 108 is provided with a rod 110 capable of cooperating with a bearing surface 106a that the rocker 106 presents. A first spring 112 keeps the rod 110 in abutment against the surface 106a. The force exerted by this spring 112 on the lock tends to move it away from the camshaft 50 and bring it back to its first position. A second spring 114 is arranged to press the rocker 106 against the slide 102.

Dans le mode de réalisation illustré, le doigt 108a bloque la rotation de i'arbre 50 lorsque la coulisse 102 est tirée, c'est-à-dire lorsqu'elle est dans sa position la plus éloignée par rapport à i'arbre 50. Les positions extrêmes de la coulisse 102 peuvent être marquées par un système de cran, avantageusement obtenu au niveau du correcteur ou du poussoir. Ainsi, lorsque l'utilisateur actionne le correcteur de manière à tirer la coulisse 102, la bascule 106 pivote et, le ressort 112 étant moins fort que le ressort 114, le verrou 108 est amené dans sa deuxième position et bloque le pivotement de l'arbre à cames 50. Inversement, lorsque la coulisse 102 est poussée, le verrou 108 revient à sa première position sous l'effet du ressort 112, libérant l'arbre à cames 50.In the illustrated embodiment, the finger 108a blocks the rotation of the shaft 50 when the slide 102 is pulled, i.e. when in its furthest position relative to the shaft 50. The extreme positions of the slide 102 may be marked by a notch system, advantageously obtained at the level of the corrector or the pusher. Thus, when the user actuates the corrector so as to pull the slide 102, the rocker 106 pivots and, the spring 112 being less strong than the spring 114, the lock 108 is brought into its second position and blocks the pivoting of the Conversely, when the slide 102 is pushed, the lock 108 returns to its first position under the effect of the spring 112, releasing the camshaft 50.

Grâce au fait que le verrou 108 et la bascule 106 ne sont pas solidaires, le verrou 108 peut être amené dans sa deuxième position par un autre dispositif. Ainsi, une deuxième bascule 116 est également montée coaxiale par rapport à la première. Cette deuxième bascule 116 est munie d'un palpeur 116a maintenu par un troisième ressort 118 en appui contre une came 120 effectuant un tour, sensiblement en une durée égale à la réserve de marche du barillet de sonnerie 10. La came 120 présente un creux disposé de manière à se présenter au niveau de la bascule lorsque la réserve de marche du barillet est inférieure à un seuil prédéterminé.Due to the fact that the lock 108 and the rocker 106 are not integral, the lock 108 can be brought into its second position by another device. Thus, a second flip-flop 116 is also mounted coaxial with respect to the first. This second flip-flop 116 is provided with a probe 116a held by a third spring 118 in abutment against a cam 120 making a turn, substantially in a duration equal to the power reserve of the striking barrel 10. The cam 120 has a recess arranged so as to be at the level of the toggles when the power reserve of the cylinder is below a predetermined threshold.

Lorsque la réserve de marche du barillet 10 devient inférieure à ce seuil prédéterminé, la bascule 116 pivote et, le ressort 112 étant moins fort que le ressort 118, le verrou 108 est amené dans sa deuxième position et bloque le pivotement de l'arbre à cames 50. Inversement, lorsque la réserve de marche repasse au-dessus du seuil prédéterminé, le verrou revient à sa première position sous l'effet du ressort 112, libérant l'arbre à cames 50.When the power reserve of the barrel 10 becomes lower than this predetermined threshold, the flip-flop 116 pivots and, the spring 112 being less strong than the spring 118, the latch 108 is brought into its second position and blocks the pivoting of the shaft. 50. Conversely, when the power reserve reverts above the predetermined threshold, the latch returns to its first position under the effect of the spring 112, releasing the camshaft 50.

Dans le cas où le système de déclenchement manuel de la sonnerie permet de réarmer le barillet de sonnerie 10, il est utile de prévoir que la sonnerie puisse se dérouler, même si le dispositif de silencieux 100 est enclenché. A cet effet, lors du déclenchement manuel, le bras 88 actionnant l'étoile 90 est disposé de manière à croiser, dans sa course, le verrou 108 si celui-ci est dans sa deuxième position, de manière à l'amener dans sa première position le temps nécessaire pour faire avancer l'arbre 50. Ce dégagement doit se faire avant que le bras 88 exerce une poussée sur l'étoile 90. Ensuite, une fois que l'arbre a pivoté, étant donné que le verrou se trouve en regard de portions non dentées de l'étoile 90, il n'exerce plus de blocage, jusqu'à ce que, à la fin de la sonnerie, il coopère avec une dent suivante.In the case where the manual triggering system for ringing can reset the barrel 10, it is useful to provide that the ringing can take place, even if the silencer device 100 is engaged. For this purpose, during manual tripping, the arm 88 actuating the star 90 is arranged to intersect, in its race, the latch 108 if it is in its second position, so as to bring it into its first position. position the time necessary to advance the shaft 50. This clearance must be done before the arm 88 exerts a thrust on the star 90. Then, once the shaft has rotated, since the lock is in Looking at the toothless portions of the star 90, it no longer locks until, at the end of the ring, it cooperates with a next tooth.

L'homme du métier pourra prévoir d'autres cames pour actionner le dispositif de silencieux. Par exemple, une came entraînée par le rouage du mouvement de base à raison d'un tour par vingt-quatre heures peut définir des parties de la journée pendant lesquelles la sonnerie au passage est enclenchée et d'autres, par exemple pendant la nuit, pendant lesquelles elle est bloquée.The skilled person may provide other cams to actuate the silencer device. For example, a cam driven by the base gear wheel at a rate of one revolution per twenty-four hours may define parts of the day during which the ringing pass is engaged and others, for example during the night, during which time she is stuck.

Ainsi est proposé un nouveau mécanisme de sonnerie permettant de gérer les différentes étapes du déroulement de la sonnerie, particulièrement dans une grande sonnerie, c'est-à-dire dans une sonnerie permettant de sonner les heures au passage ou à la demande. Le mode de réalisation présenté ci-dessus n'est qu'une illustration non limitative de l'invention dont l'essentiel est d'utiliser un différentiel pour gérer les étapes de la sonnerie. L'homme du métier pourra facilement adapter divers éléments de liaison entre l'organe de commande et les entrées du différentiel sans sortir du cadre de i'invention. Il pourra également trouver d'autres solutions que celles proposées pour faire avancer i'arbre à cames. Ainsi, au lieu d'utiliser une roue de transmission pour faire passer l'arbre de sa première à sa deuxième configuration, on peut prévoir d'effectuer cet entraînement par l'intermédiaire d'un élément de transmission lié au râteau, à l'instar du doigt 94, entraînant i'arbre une fois que les râteaux sont tombés sur leur limaçon.Thus is proposed a new ringing mechanism for managing the various stages of the course of the ring, especially in a large ring, that is to say, in a ringing ring to ring the hours in passing or on demand. The embodiment presented above is only a non-limiting illustration of the invention whose essential is to use a differential to handle the steps of the ring. The skilled person can easily adapt various connecting elements between the control member and the inputs of the differential without departing from the scope of the invention. He may also find other solutions than those proposed to advance the camshaft. Thus, instead of using a transmission wheel to move the shaft from its first to its second configuration, it can be provided to carry out this drive via a transmission element connected to the rake, to the 94, dragging the tree once the rakes have fallen on their snail.
