Conformément à l'invention, la roue de commande 16 comprend une première roue d'entrainement 30 solidaire de la came de commande 18 et agencée pour être actionnée par le crochet 20a de la commande secondaire 20, et une deuxième roue d'entrainement 32 agencée pour être actionnée par le crochet 14a de la commande principale 14. Les première et deuxième roues d'entrainement 30 et 32 sont identiques, avec le même nombre de dents, et sont superposées de manière coaxiale, sans déphasage de l'une par rapport à l'autre.According to the invention, the control wheel 16 comprises a first drive wheel 30 integral with the control cam 18 and arranged to be actuated by the hook 20a of the secondary drive 20, and a second drive wheel 32 arranged to be actuated by the hook 14a of the main control 14. The first and second drive wheels 30 and 32 are identical, with the same number of teeth, and are superimposed coaxially, without a phase shift of one with respect to the other.

De préférence, les première et deuxième roues d'entrainement 30 et 32 sont des roues à rochet, et les colonnes 18a de la came de commande 18 sont disposées perpendiculairement auxdites première et deuxième roues d'entrainement 30 et 32, de sorte que la roue de commande 16 formée par les roues d'entrainement 30, 32 et la came de commande 18 est de type roue à colonnes. Le mécanisme étant à deux temps, les roues d'entrainement 30 et 32 comprennent deux fois plus de dents que de colonnes 18a sur la came de commande 18.Preferably, the first and second drive wheels 30 and 32 are ratchet wheels, and the columns 18a of the control cam 18 are arranged perpendicular to said first and second drive wheels 30 and 32, so that the control wheel 16 formed by the drive wheels 30, 32 and the control cam 18 is of the column wheel type. The mechanism being two-stroke, the drive wheels 30 and 32 include twice as many teeth as columns 18a on the control cam 18.

Les première et deuxième roues d'entrainement 30, 32 sont montées libres en rotation autour d'un même axe (non représenté) solidaire d'un élément de bâti du mouvement.The first and second drive wheels 30, 32 are mounted to rotate freely about the same axis (not shown) integral with a frame element of the movement.

Comme le montre plus précisément la figure 2, la deuxième roue d'entrainement 32 est reliée à la première roue d'entrainement 30 par un élément de couplage élastique 34, tel qu'un ressort cliquet, agencé pour lier solidairement en rotation la deuxième roue d'entrainement 32 à la première roue d'entrainement 30 lorsque seule la deuxième roue d'entrainement 32 est actionnée par le crochet 14a de la commande principale 14 si la commande secondaire 20 est passée à l'état déverrouillé et qu'alors seule la commande principale 14 est actionnée lors du prochain actionnement manuel via le premier organe de commande 12. A cet effet, l'élément de couplage élastique 34 présente une première extrémité 34a rendue solidaire de la première roue d'entrainement 30 au moyen d'une goupille par exemple, pour laquelle seul l'orifice d'introduction 36 a été représenté sur la première roue d'entrainement 30. L'élément de couplage élastique 34 comprend également une seconde extrémité 34b en contact avec une paroi interne 32a de la deuxième roue d'entrainement 32. Ladite paroi interne 32a présente la forme d'une denture configurée pour que la seconde extrémité 34b de l'élément de couplage élastique 34 constitue un cliquet, de manière à lier solidairement en rotation la deuxième roue d'entrainement 32 à la première roue d'entrainement 30 lorsque seule la deuxième roue d'entrainement 32 est actionnée par le crochet 14a de la commande principale 14, et pour désolidariser la deuxième roue d'entrainement 32 de la première roue d'entrainement 30 lorsque seule la première roue d'entrainement 30 est actionnée par le crochet 20a de la commande secondaire 20. Ainsi, lorsque seule la commande principale 14 est actionnée, elle entraine en rotation, par son crochet 14a, la deuxième roue d'entrainement 32 de sorte que la première roue d'entrainement 30, et donc la came de commande 18, sont également entrainées en rotation via le couplage réalisé par l'élément de couplage élastique 34. Lorsque seule la commande secondaire 20 est actionnée, elle entraine en rotation, par son crochet 20a, la première roue d'entrainement 30, et donc la came de commande 18, la deuxième roue d'entrainement 32 restant immobile puisqu'elle s'est désolidarisée de la première roue d'entrainement 30 par décliquetage de la seconde extrémité 34b de l'élément de couplage élastique 34 sur sa paroi 32a.As more specifically shown in the figure 2 , the second drive wheel 32 is connected to the first drive wheel 30 by an elastic coupling element 34, such as a pawl spring, arranged to securely connect in rotation the second drive wheel 32 to the first wheel drive 30 when only the second drive wheel 32 is actuated by the hook 14a of the main control 14 if the secondary control 20 has gone to the unlocked state and then only the main control 14 is activated during the next manual actuation via the first control member 12. For this purpose, the elastic coupling element 34 has a first end 34a made integral with the first drive wheel 30 by means of a pin for example, for which only the introduction orifice 36 has been shown on the first drive wheel 30. The elastic coupling element 34 also comprises a second end 34b in contact with an internal wall 32a of the second drive wheel. ment 32. Said internal wall 32a has the shape of a toothing configured so that the second end 34b of the elastic coupling element 34 constitutes a pawl, so as to securely connect in rotation the second drive wheel 32 to the first drive wheel 30 when only the second drive wheel 32 is actuated by the hook 14a of the main drive 14, and to separate the second drive wheel 32 from the first drive wheel 30 when only the first drive wheel 30 is actuated by the hook 20a of the secondary control 20. Thus, when only the main control 14 is actuated, it rotates, by its hook 14a, the second drive wheel 32 so that the first drive wheel 30, and therefore the control cam 18, are also driven in rotation via the coupling produced by the elastic coupling element 34. When only the secondary control 20 is actuated, it drives in rotation, by its hook 20a, the first drive wheel 30, and therefore the control cam 18, the second drive wheel 32 remaining stationary since it has become detached from the first drive wheel 30 by unclipping the second end 34b of the elastic coupling element 34 on its wall 32a.

Le crochet de verrouillage 40 comprend également un deuxième bras 40c agencé pour pouvoir venir en appui et coopérer avec la goupille 39 de la bascule de commande 38 de sorte que le crochet de verrouillage est commandé par ladite bascule de commande 38 actionnée par le deuxième organe de commande 26 pour pivoter dans le sens antihoraire et passer à l'état déverrouillé. Le crochet de verrouillage 40 comprend également un troisième bras 40d agencé pour coopérer avec un ressort de rappel 42.The locking mechanism also comprises a locking hook 40 pivotally mounted in C on the arm 15 of the main control 14. The locking hook 40 comprises a first arm 40a having at its end a hook 40b arranged to mate with a hook. 20b provided on the secondary control 20 in order to lock said secondary control 20 in rotation on the main control 14 in the locked state. The locking hook 40 also comprises a second arm 40c arranged to be able to come to bear and cooperate with the pin 39 of the control rocker 38 so that the locking hook is controlled by said control rocker 38 actuated by the second control member 26 to pivot counterclockwise and switch to the state unlocked. The locking hook 40 also comprises a third arm 40d arranged to cooperate with a return spring 42.

Le crochet de verrouillage 40 est également agencé pour pouvoir ensuite coopérer avec la commande secondaire 20, lors du prochain actionnement manuel de la commande principale 14, pour passer dans la position de verrouillage, puis à l'état verrouillé. Plus spécifiquement, le crochet 40b du crochet de verrouillage 40 présente un nez dont le flan présente une géométrie adaptée à celle du flan du nez du crochet 20b de la commande secondaire 20 de sorte que le crochet de verrouillage 40 coopérant avec la commande secondaire 20 lors du prochain actionnement manuel de la commande principale 14, pourra pivoter dans le sens antihoraire et passer dans la position de verrouillage avec le crochet 20b de ladite commande secondaire 20, puis pivoter dans le sens horaire et revenir à l'état verrouillé.The locking hook 40 is also designed to then be able to cooperate with the secondary control 20, during the next manual actuation of the main control 14, to go into the locking position, then to the locked state. More specifically, the hook 40b of the locking hook 40 has a nose whose blank has a geometry adapted to that of the blank of the nose of the hook 20b of the secondary control 20 so that the locking hook 40 cooperates with the secondary control 20 during the next manual actuation of the main control 14, can pivot counterclockwise and go into the locking position with the hook 20b of said secondary control 20, then rotate clockwise and return to the locked state.

Il est précisé qu'en plus de ceux déjà décrits, tous les éléments tels que bascules, commandes, pinces, crochets du mécanisme décrit ci-dessus sont soumis à leurs propres ressorts de rappel non représentés.It is specified that in addition to those already described, all the elements such as rockers, controls, clamps, hooks of the mechanism described above are subjected to their own return springs, not shown.

Le fonctionnement du dispositif de commande de l'invention est décrit ci-dessous en référence aux figures 4 à 9. Dans cet exemple, le dispositif de commande est une commande START/STOP d'un mécanisme de chronographe compte à rebours, le mécanisme horloger à commander étant le dispositif d'embrayage du chronographe, le deuxième organe de commande 26 étant un crochet commandé par un mécanisme 28 de fin de décompte agencé pour faire pivoter ledit deuxième organe de commande 26 à la fin du décompte.The operation of the control device of the invention is described below with reference to the figures 4 to 9 . In this example, the control device is a START / STOP control of a countdown chronograph mechanism, the watch mechanism to be controlled being the chronograph clutch device, the second control member 26 being a hook controlled by a end of count mechanism 28 arranged to pivot said second control member 26 at the end of the count.

La position STOP de départ est représentée sur la figure 1, dans laquelle le dispositif de commande 1 est prêt à fonctionner. Dans cette position STOP, le mécanisme de chronographe compte à rebours est inactif. Seule tourne la roue de seconde 6 du mouvement horloger de base. La commande secondaire 20 et le mécanisme de verrouillage sont à l'état verrouillé, le crochet 40b du crochet de verrouillage 40 étant accouplé au crochet 20b de la commande secondaire 20 et son premier bras 40a est en appui sur la goupille 17 de la commande principale 14. La commande secondaire 20 est donc verrouillée en rotation avec la commande principale 14, l'organe élastique 22 étant armé. La commande secondaire 20 est superposée à la commande principale 14 de sorte que leurs crochets 20a et 14a sont superposés, le crochet 20a coopérant avec la première roue d'entrainement 30 de la roue de commande 16 et le crochet 14a coopérant avec la deuxième roue d'entrainement 32. La roue de commande 16 est positionnée de sorte que la pince de commande d'embrayage 8 est dans un vide entre deux colonnes 18a de la came de commande 18, positionnée avec l'autre pince 10 en position fermée pour débrayer la roue de seconde 6 et le mobile entraineur chronographe 4. La bascule de commande 38 est maintenue par son bec 38a par le deuxième organe de commande 26.The starting STOP position is shown on the figure 1 , in which the control device 1 is ready to operate. In this STOP position, the Countdown chronograph mechanism is inactive. Only the 6 second wheel of the basic watch movement turns. The secondary control 20 and the locking mechanism are in the locked state, the hook 40b of the locking hook 40 being coupled to the hook 20b of the secondary control 20 and its first arm 40a is supported on the pin 17 of the main control. 14. The secondary control 20 is therefore locked in rotation with the main control 14, the elastic member 22 being armed. The secondary control 20 is superimposed on the main control 14 so that their hooks 20a and 14a are superimposed, the hook 20a cooperating with the first drive wheel 30 of the control wheel 16 and the hook 14a cooperating with the second wheel d drive 32. The control wheel 16 is positioned so that the clutch control clamp 8 is in a vacuum between two columns 18a of the control cam 18, positioned with the other clamp 10 in the closed position to disengage the clutch. second wheel 6 and the mobile chronograph drive 4. The control lever 38 is held by its beak 38a by the second control member 26.

En référence à la figure 4, lorsqu'un utilisateur exerce une pression, représentée par la flèche F, sur le premier organe de commande 12 du dispositif de commande 1, pour déclencher le START, la commande principale 14 bascule en A dans le sens horaire. La commande secondaire 20 étant verrouillée en rotation sur la commande principale 14 par le crochet de verrouillage 40 embarqué sur ladite commande principale 14, pivote de la même manière en A, de sorte que leurs crochets 14a et 20a agissent simultanément respectivement sur la deuxième roue d'entrainement 32 et sur la première roue d'entrainement 30 de la roue de commande 16, faisant tourner la came de commande 18 d'un pas dans le sens antihoraire, l'élément de couplage élastique 34 n'étant pas sollicité. La pince de commande d'embrayage 8 monte sur une colonne 18a de sorte qu'elle pivote dans le sens horaire, l'autre pince 10 pivotant dans le sens antihoraire pour se positionner en position ouverte afin d'embrayer la roue de seconde 6 et le mobile entraineur chronographe 4 pour déclencher le chronographe. La bascule de commande 38 reste à l'état verrouillé, bloquée par le deuxième organe de commande 26.With reference to the figure 4 , when a user exerts a pressure, represented by the arrow F, on the first control member 12 of the control device 1, to trigger the START, the main control 14 switches to A in the clockwise direction. The secondary control 20 being locked in rotation on the main control 14 by the locking hook 40 on board said main control 14, pivots in the same way at A, so that their hooks 14a and 20a act simultaneously respectively on the second wheel d drive 32 and on the first drive wheel 30 of the drive wheel 16, rotating the drive cam 18 one step counterclockwise, the resilient coupling member 34 not being biased. The clutch control clamp 8 mounts on a column 18a so that it rotates clockwise, the other clamp 10 rotates counterclockwise to position itself in the open position to engage the second wheel 6 and the cellphone chronograph trainer 4 to start the chronograph. The control rocker 38 remains in the locked state, blocked by the second control member 26.

En référence à la figure 5, la phase de START se termine par le retour de la commande principale 14 dans sa position initiale sous l'action de son ressort de rappel, représentée par la flèche F'. La commande secondaire 20 toujours verrouillée sur la commande principale 14 par le crochet de verrouillage 40 reprend également sa position initiale, superposée à la commande principale 14. Le décompte est en cours.With reference to the figure 5 , the START phase ends with the return of the main control 14 to its initial position under the action of its return spring, represented by the arrow F '. The secondary control 20 still locked on the main control 14 by the locking hook 40 also returns to its initial position, superimposed on the main control 14. The count is in progress.

Tant que le mécanisme de verrouillage est à l'état verrouillé comme représenté sur les figures 4 et 5, la commande secondaire 20 est solidaire en rotation de la commande principale 14. Ainsi, l'utilisateur peut faire des appuis successifs sur le premier organe de commande 12 pour enchainer des phases STOP et START en faisant, à chaque pression sur le premier organe de commande 12, tourner d'un pas la roue de commande 16 par traction simultané des crochets 20a et 14a sur ses roues d'entrainement 30, 32 respectivement, pour alternativement fermer et ouvrir de nouveau les pinces 8 et 10, de la même manière qu'expliqué ci-dessus.As long as the locking mechanism is in the locked state as shown in the figures 4 and 5 , the secondary control 20 is integral in rotation with the main control 14. Thus, the user can make successive presses on the first control member 12 to chain STOP and START phases by making, on each press on the first member of control 12, turn the control wheel 16 by one step by simultaneously pulling the hooks 20a and 14a on its drive wheels 30, 32 respectively, to alternately close and reopen the clamps 8 and 10, in the same way as 'explained above.

En référence à la figure 6, lorsque le décompte se termine et arrive à zéro, le mécanisme 28 de fin de décompte fait pivoter ledit deuxième organe de commande 26 de sorte qu'il libère la bascule de commande 38 qui pivote en B dans le sens antihoraire, sous l'effet de son ressort de rappel (non représenté).With reference to the figure 6 , when the counting ends and reaches zero, the end of counting mechanism 28 rotates said second control member 26 so that it releases the control lever 38 which pivots in B in the counterclockwise direction, under the effect of its return spring (not shown).

En référence à la figure 7, la bascule de commande 38, libérée, pivote suffisamment pour que sa goupille 39 vienne, dans sa course, coopérer avec le deuxième bras 40c du crochet de verrouillage 40 de manière à faire pivoter en C le crochet de verrouillage 40 dans le sens antihoraire. Le crochet de verrouillage 40 passe alors à l'état déverrouillé, son crochet 40b s'étant éloigné et séparé du crochet 20b de la commande secondaire 20. La commande secondaire 20 est alors également à l'état déverrouillé, désolidarisée de la commande principale 14, de sorte que, grâce à l'énergie fournie par l'organe élastique 22 qui se désarme, ladite commande secondaire 20 libérée pivote seule en A dans le sens horaire en actionnant, par son crochet 20a, la première roue d'entrainement 30 de la roue de commande 16 dans le sens antihoraire. Cela correspond à un STOP automatique, au cours duquel la roue de commande 16 est actionnée de manière automatique uniquement par la commande secondaire 20, la commande principale 14 et la deuxième roue d'entrainement 32 étant restées immobiles, et l'élément de couplage élastique 34 ayant décliqueté. La commande secondaire 20 n'est plus superposée à la commande principale 14. La rotation de la came de commande 18 d'un pas commande la fermeture des pinces d'embrayage 8 et 10, de manière à débrayer la roue de seconde 6 et le mobile entraineur chronographe 4, ce qui entraine l'arrêt du chronographe.With reference to the figure 7 , the control lever 38, released, pivots sufficiently so that its pin 39 comes, in its course, to cooperate with the second arm 40c of the locking hook 40 so as to cause the locking hook 40 to pivot in the counterclockwise direction. The locking hook 40 then goes into the unlocked state, its hook 40b having moved away and separated from the hook 20b of the secondary control 20. The secondary control 20 is then also in the unlocked state, separated from the main control 14. , so that, thanks to the energy supplied by the elastic member 22 which disarms, said released secondary control 20 pivots only in A in the clockwise direction by actuating, by its hook 20a, the first drive wheel 30 of the control wheel 16 counterclockwise. This corresponds to an automatic STOP, during which the control wheel 16 is actuated automatically only by the secondary control 20, the main control 14 and the second drive wheel 32 having remained stationary, and the elastic coupling element 34 having clicked. The secondary control 20 is no longer superimposed on the main control 14. The rotation of the control cam 18 by one step controls the closing of the clutch clamps 8 and 10, so as to disengage the second wheel 6 and the mobile chronograph trainer 4, which causes the stop of the chronograph.

En référence à la figure 8, la fonction automatique de la commande secondaire 20 est rendue de nouveau opérationnelle pour la prochaine utilisation du chronographe, grâce au passage du mécanisme de verrouillage dans sa position de verrouillage lorsque le prochain START est déclenché suite à une nouvelle pression de l'utilisateur sur le premier organe de commande12, avant de revenir à l'état verrouillé.With reference to the figure 8 , the automatic function of the secondary control 20 is made operational again for the next use of the chronograph, thanks to the passage of the locking mechanism in its locked position when the next START is triggered following a new pressure from the user on the first control unit12, before returning to the locked state.

Lorsqu'un utilisateur commence à exercer une nouvelle pression, représentée par la flèche F, sur le premier organe de commande 12 du dispositif de commande 1, pour déclencher un nouveau START, la commande principale 14 commence à basculer en A dans le sens horaire.When a user begins to exert a new pressure, represented by the arrow F, on the first control member 12 of the control device 1, to trigger a new START, the main control 14 begins to switch to A in the clockwise direction.

La commande secondaire 20 étant dans son état déverrouillé, libre et désolidarisée en rotation de la commande principale 14, seule la commande principale 14 pivote en A pour actionner la roue de commande 16, son crochet 14a actionnant la deuxième roue d'entrainement 32 de la roue de commande 16 dans le sens antihoraire, entrainant en rotation dans le sens antihoraire la première roue d'entrainement 30, le crochet 20a étant sans effet, et donc la came de commande 18, via le couplage réalisé par l'élément de couplage élastique 34, comme décrit ci-dessus. La rotation d'un pas de la came de commande 18 commande une nouvelle ouverture des pinces 8 et 10.The secondary control 20 being in its unlocked state, free and disconnected in rotation from the main control 14, only the main control 14 pivots at A to actuate the control wheel 16, its hook 14a actuating the second drive wheel 32 of the control wheel 16 counterclockwise, rotating counterclockwise the first drive wheel 30, the hook 20a having no effect, and therefore the control cam 18, via the coupling produced by the elastic coupling element 34, as described above. The rotation of one step of the control cam 18 controls a new opening of the clamps 8 and 10.

En parallèle, la commande principale 14 en basculant permet le réarmage de l'organe élastique 22. D'autre part, lors du basculement de la commande principale 14, sa goupille 17 vient, dans sa course, coopérer avec le doigt 38b de la bascule de commande 38, de manière à la faire pivoter en B dans le sens horaire, en position de verrouillage, en escamotant le deuxième organe de commande 26. Lors de son pivotement, la bascule de commande 38 permet également le réarmage de son ressort de rappel. En même temps, le crochet 40b du crochet de verrouillage 40, embarqué sur la commande principale 14, rentre en contact du crochet 20b de la commande secondaire 20, la géométrie des flans des nez desdits crochets 20b et 40b provoquant la rotation du crochet de verrouillage 40 en C dans le sens antihoraire. Ainsi, le crochet de verrouillage 40 se dégage pour passer en position de verrouillage afin de permettre à la commande principale 14 de revenir se superposer à la commande secondaire 20 sans être gênée.In parallel, the main control 14 by tilting allows the resetting of the elastic member 22. On the other hand, when the main control 14 is tilted, its pin 17 comes, in its course, to cooperate with the finger 38b of the rocker. control 38, so as to make it pivot at B in the clockwise direction, in the locked position, by retracting the second control member 26. When it is pivoted, the control lever 38 also allows the re-winding of its return spring . At the same time, the hook 40b of the locking hook 40, on board the main control 14, comes into contact with the hook 20b of the secondary control 20, the geometry of the blanks of the noses of said hooks 20b and 40b causing the locking hook to rotate. 40 in C counterclockwise. Thus, the locking hook 40 is released to pass into the locking position in order to allow the main control 14 to return to superimpose itself on the secondary control 20 without being hampered.

En référence à la figure 9, à la fin du basculement uniquement de la commande principale 14 en A, lorsque le premier organe de commande 12 a été poussé à fond selon la flèche F, la commande principale 14 est revenue en position superposée à la commande secondaire 20, de sorte que le crochet 40b du crochet de verrouillage 40 vient s'engager dans le crochet 20b de ladite commande secondaire 20. Une fois son crochet 40b engagé, ledit crochet de verrouillage 40 pivote dans le sens horaire pour bloquer le crochet 20b de la commande secondaire 20 et revenir à l'état verrouillé. L'organe élastique 22 est entièrement réarmé. En parallèle, la bascule de commande 38 a terminé son pivotement en se positionnant sous le deuxième organe de commande 26.With reference to the figure 9 , at the end of the tilting only of the main control 14 in A, when the first control member 12 has been pushed fully according to the arrow F, the main control 14 has returned to the position superimposed on the secondary control 20, so that the hook 40b of the locking hook 40 engages the hook 20b of the said secondary control 20. Once its hook 40b is engaged, the said locking hook 40 pivots clockwise to block the hook 20b of the secondary control 20 and return to the locked state. The elastic member 22 is fully reset. In parallel, the control lever 38 has completed its pivoting by positioning itself under the second control member 26.

Cette phase de START se termine par le retour en position initiale de la commande principale 14, sous l'action de son ressort de rappel, ainsi que de la commande secondaire 20, de nouveau à l'état verrouillé sur la commande principale 14 au moyen du crochet de verrouillage 40. La bascule de commande 38 est également revenue à l'état verrouillé, maintenue par le deuxième organe de commande 26. La fonction automatique de la commande secondaire 20 est de nouveau opérationnelle. Cette position à l'état verrouillé est identique à celle de la figure 5.This START phase ends with the return to the initial position of the main control 14, under the action of its return spring, as well as of the secondary control 20, again in the locked state on the control. main 14 by means of the locking hook 40. The control rocker 38 has also returned to the locked state, maintained by the second control member 26. The automatic function of the secondary control 20 is again operational. This position in the locked state is identical to that of the figure 5 .

La présente invention permet d'avoir un dispositif de commande d'un mécanisme horloger pouvant être actionné par un utilisateur, mais également par une commande interne liée à un autre mécanisme du mouvement, de manière à disposer d'une commande automatique, en plus d'une commande manuelle dudit mécanisme.The present invention makes it possible to have a control device for a watch mechanism that can be operated by a user, but also by an internal control linked to another mechanism of the movement, so as to have an automatic control, in addition to 'manual control of said mechanism.
