Description

La présente invention concerne un dispositif de sonnerie pour une pièce d'horlogerie mécanique ; elle concerne aussi un mouvement de montre muni d'un tel dispositif de même qu'une pièce d'horlogerie muni d'un tel mouvement comprenant un tel dispositif.The present invention relates to a striking device for a mechanical timepiece; it also relates to a watch movement provided with such a device as well as a timepiece provided with such a movement comprising such a device.

Les horlogers ont de tous temps introduit des dispositifs permettant notamment la sonnerie des heures dans leurs pièces d'horlogerie. En particulier pour les pièces d'horlogerie portables, que ce soit une montre à gousset, une montre bracelet ou autre pièce portable, une complication consiste à introduire une sonnerie des heures à répétition. Différents dispositifs ont été proposés à cet effet, comprenant une pluralité de leviers et cames afin de permettre de réaliser la fonction désirée.Watchmakers have, at all times, introduced devices that allow the ringing of hours in their timepieces. Especially for portable timepieces, whether it is a pocket watch, a wristwatch or other portable piece, a complication is to introduce a ring of hours to repetition. Various devices have been proposed for this purpose, comprising a plurality of levers and cams to enable the desired function to be achieved.

Ces pièces d'horlogerie connues munies de tels dispositifs possèdent quelques inconvénients.These known timepieces equipped with such devices have some disadvantages.

En particulier, le réglage de la sonnerie se fait généralement de manière indépendante de celui du mouvement d'horlogerie, respectivement de celui de l'affichage des heures. Ceci est un inconvénient majeur pour les montres modernes pour lesquelles le système actuel de passage de l'heure d'été à l'heure d'hiver et vice-versa, de même que la possibilité pour le porteur d'effectuer des voyages traversant plusieurs fuseaux horaires impose de nombreux réglages de l'heure affichée ainsi que de celui du dispositif de sonnerie.In particular, the setting of the ring is generally independent of that of the clockwork, respectively that of the display of hours. This is a major disadvantage for modern watches for which the current system of transition from summer time to winter time and vice versa, as well as the possibility for the wearer to make trips through several time zones imposes many settings of the time displayed as well as that of the ringing device.

Un autre inconvénient des dispositifs connus à leviers et cames est que lorsqu'on tente d'effectuer un réglage du dispositif de sonnerie alors que la sonnerie est en cours de fonctionnement, on peut arriver à provoquer des dégâts au mécanisme, voire au bris de certaines pièces.Another disadvantage of the known levers and cams devices is that when attempting to adjust the ringing device while the ring is in operation, it can happen to cause damage to the mechanism or break some of rooms.

De plus, de par les mouvements non linéaires ou non continus des dispositifs à leviers et cames connus, ces dispositifs sont généralement difficiles à mettre au point, à régler et à utiliser ; ils sont en outre généralement assez onéreux.Moreover, because of the non-linear or non-continuous movements of known levers and cams, these devices are generally difficult to develop, adjust and use; In addition, they are generally quite expensive.

Il est connu par ailleurs, notamment du document US 1 811 791 , un mécanisme d'horloge à sonnerie fournissant une forme spéciale d'interrupteur pour commander l'action du train de rouage frappante tel que déterminé par le mouvement du train.It is also known from the document US 1,811,791 a striking clock mechanism providing a special form of switch for controlling the action of the striking train gear as determined by the movement of the train.

Il est également connu, notamment du document CH 689 337 , une pièce d'horlogerie à carillon équipé d'un mécanisme de sonnerie comportant, agencées sur l'axe du centre, quatre cames de quarts, destinées à coopérer avec pièces de quarts, et un limaçon et une surprise des minutes destinée à coopérer avec une pièce des minutes. Le mécanisme de sonnerie comprend en outre un mécanisme de sonnerie des heures.It is also known, particularly from the document CH 689 337 , a carillon timepiece equipped with a striking mechanism comprising, arranged on the axis of the center, four cams of quarters, intended to cooperate with parts of quarters, and a snail and a surprise minutes intended to cooperate with a minute room. The striking mechanism further includes a clock striking mechanism.

Le but de l'invention est donc de proposer un dispositif de sonnerie pour une pièce d'horlogerie exempt des inconvénients connus des dispositifs de l'art antérieur, en particulier dont l'heure à sonner corresponde exactement à l'heure affichée, quel que soit le réglage positif ou négatif effectué sur cette dernière, un réglage effectué en cours de sonnerie n'entraînant pas de dégâts et qui soit relativement facile à mettre au point, à régler et utiliser. Ce dispositif étant moins complexe que les dispositifs connus, il sera moins onéreux.The object of the invention is therefore to propose a striking device for a timepiece free from the known drawbacks of the devices of the prior art, in particular whose time to ring corresponds exactly to the time displayed, whatever either the positive or negative setting on the latter, a setting made during ringing that does not cause damage and is relatively easy to debug, adjust and use. This device is less complex than the known devices, it will be less expensive.

Ce but est atteint par un dispositif de sonnerie pour une pièce d'horlogerie tel que décrit dans la revendication 1, des formes d'exécution particulières et variantes étant décrites dans les revendications dépendantes.This object is achieved by a striking device for a timepiece as described in claim 1, particular embodiments and variants being described in the dependent claims.

Une première forme d'exécution d'un dispositif de sonnerie pour une pièce d'horlogerie est décrite en bétails ci-dessous cette description étant à considérer en regard du dessin annexé comportant les figures où :

  • la figure 1 est un schéma montrant les différents élément constitutifs du dispositif disposés chacun selon son axe, son niveau et son type d'engrènement,
  • la figure 2 montre une portion du dispositif définissant la fonction heure à sonner,
  • la figure 3 montre une autre portion du dispositif en position de non-sonnerie,

  • la figure 11 montre la même portion du dispositif que celle de la figure 8, en position de fin de sonnerie.
A first embodiment of a striking device for a timepiece is described in cattle below this description to be considered with reference to the accompanying drawing comprising the figures where:
  • the figure 1 is a diagram showing the different constituent elements of the device each arranged along its axis, its level and its type of meshing,
  • the figure 2 shows a portion of the device defining the time function to ring,
  • the figure 3 shows another portion of the device in the non-ringing position,

  • the figure 10 shows the same portion of the device as that of the preceding figure, in end of ringing position,
  • the figure 11 shows the same portion of the device as that of the figure 8 , in the end of ringing position.

Dans la description qui suit ainsi que dans les figures et les revendications, une convention de numérotation des axes et des roues a été adoptée afin de faciliter la compréhension du fonctionnement du dispositif. Selon cette convention, chaque roue ou pignon est généralement repéré par un nombre à 3 chiffres ; le premier indique l'axe sur lequel est monté le pignon ou la roue et les deux derniers indiquent le niveau d'engrènement. Ainsi, par exemple, les roues ou pignons 7xx sont disposés sur le même axe et tournent ensemble, alors que les roues y05 et z05 engrènent ensemble. Une exception à ce système de numérotation est faite pour l'axe No 3, qui comprend en fait les axes 30 et 31, disposés coaxialement dans la forme d'exécution décrite, mais pouvant tourner indépendamment comme il sera décrit plus bas ; en conséquence, les roues montées sur ces deux derniers axes sont repérées par un nombre à 4 chiffres.In the following description as well as in the figures and claims, a numbering convention of the axes and wheels has been adopted in order to facilitate the understanding of the operation of the device. According to this convention, each wheel or pinion is generally identified by a 3-digit number; the first indicates the axis on which the pinion or the wheel is mounted and the last two indicate the level of meshing. Thus, for example, the wheels or sprockets 7xx are arranged on the same axis and rotate together, while the wheels y05 and z05 mesh together. An exception to this numbering system is made for the axis No. 3, which comprises in fact the axes 30 and 31, arranged coaxially in the embodiment described, but can rotate independently as will be described below; consequently, the wheels mounted on these last two axes are indicated by a 4-digit number.

La figure 1 est un schéma montrant les différents axes, les différents niveaux d'engrènement ainsi que les roue et pignons qui y sont montés. Cette figure sert essentiellement à repérer les positions relatives des différents éléments représentés sur les figures qui suivent.The figure 1 is a diagram showing the different axes, the different levels of meshing as well as the wheels and gears which are there mounted. This figure serves essentially to identify the relative positions of the various elements shown in the figures that follow.

La figure 2 montre une portion du dispositif permettant de déterminer l'heure à sonner. Selon la forme d'exécution représentée ici, l'axe 1, portant la roue 101 effectue 1 tour en 1 heure, dans le sens horaire ; sa rotation est commandée par le mouvement de la pièce d'horlogerie schématisé en 100 sur la figure 1. La dent unique de la roue 101 actionne, 1 fois par heure, un pignon intermédiaire 201, qui incrémente, dans le sens horaire, la roue 3001 (48 dents) de 1/24 ème de tour toutes les heures.The figure 2 shows a portion of the device for determining the time to ring. According to the embodiment shown here, the axis 1, carrying the wheel 101 makes 1 turn in 1 hour, clockwise; its rotation is controlled by the movement of the timepiece schematized in 100 on the figure 1 . The single tooth of the wheel 101 operates, 1 time per hour, an intermediate gear 201, which increments, clockwise, the wheel 3001 (48 teeth) of 1 / 24th of a turn every hour.

Sur la figure 1 on voit que l'axe 30 portant la roue 3001 est coaxial à l'axe 31 portant les roues 3104 et 3105. Lors du mouvement d'incrémentation de la roue 3001 décrit plus haut, les roues 3104 et 3105 suivent ce même mouvement d'incrémentation, des moyens de positionnement, schématisés par le ressort 32 sur la figure 1, entraînant simultanément l'axe 31 avec l'axe 30 dans le sens horaire.On the figure 1 it can be seen that the axle 30 carrying the wheel 3001 is coaxial with the axle 31 carrying the wheels 3104 and 3105. During the incrementing movement of the wheel 3001 described above, the wheels 3104 and 3105 follow this same movement. incrementation, positioning means, schematized by the spring 32 on the figure 1 , simultaneously driving the axis 31 with the axis 30 in the clockwise direction.

La figure 3 montre le dispositif d'entraînement de la sonnerie en position de non-sonnerie. Ce dispositif comprend un axe 4 portant un plateau 407 muni d'une goupille 41, ainsi qu'un pignon intermédiaire 402 en engrènement avec une roue intermédiaire 502 solidaire d'un pignon 503 engrenant sur une roue de marteau 603. Cette dernière engrène d'une part sur une roue d'entraîneur 803 et d'autre part sur un pignon de commande 703. Sur la figure on voit encore une came de commande 907, montée sur l'axe 9 en liaison avec un pignon de l'axe 7 d'une manière qui sera décrite plus bas, ainsi que l'encombrement montré en traits discontinus d'une roue montée sur l'axe 31. On y voit aussi une bascule de commande 60, actuellement verrouillée en position de non-sonnerie par un bras 62 logé dans un creux de la came de commande 907, un autre bras 61 étant engagé avec la goupille 41 du plateau 407, son dernier bras 63 maintenant l'axe 8 de manière à ce qu'aucune des roues portées par cet axe n'entre en engrènement avec une roue portée par l'axe 31. Un barillet de sonnerie schématisé en 69 sur la figure 1 alimente le dispositif en énergie, de préférence via son axe 6.The figure 3 shows the ringer drive in the non-ringing position. This device comprises an axis 4 carrying a plate 407 provided with a pin 41, and an intermediate gear 402 meshing with an intermediate wheel 502 integral with a pinion 503 meshing on a hammer wheel 603. The latter meshes with a part on a drive wheel 803 and secondly on a control pinion 703. In the figure we still see a control cam 907, mounted on the axis 9 in connection with a pinion of the axis 7 d a manner which will be described below, as well as the bulkiness shown in broken lines of a wheel mounted on the axis 31. It also shows a control rocker 60, currently locked in the non-ringing position by an arm 62 housed in a recess of the control cam 907, another arm 61 being engaged with the pin 41 of the plate 407, its last arm 63 maintaining the axis 8 so that none of the wheels carried by this axis n ' intermesh with a wheel by axis 31. A ringing barrel schematized in 69 on the figure 1 supplies the device with energy, preferably via its axis 6.

Dans la position de la bascule de commande représentée sur cette figure, l'ensemble du dispositif est au repos, le mouvement de rotation du rouage étant bloqué par la goupille 41 du plateau 407 engagée par le bras 61.In the position of the control lever shown in this figure, the entire device is at rest, the rotational movement of the gear being blocked by the pin 41 of the plate 407 engaged by the arm 61.

La figure 4 montre une portion du dispositif dans le même état que celui de la figure précédente, vu à un autre étage des roues d'engrènement.The figure 4 shows a portion of the device in the same state as that of the previous figure, seen on another floor of the meshing wheels.

Comme on le voit, les axes 7 et 9 portent chacun un pignon, respectivement 706 et 906 de chacun 12 dents, continuellement engagés ensemble, faisant que ces deux axes sont simultanément immobiles ou en rotation. L'axe 7 porte en plus un premier pignon de commande 705 muni ici de 4 dents sur 8, susceptible d'être actionné par une roue 3105, munie de 2 dents en opposition, montée sur l'axe 31. L'axe 9 porte de même une came de verrouillage de marteau 908 qui, selon sa position représentée sur la figure, bloque le marteau de sonnerie 90 en position verrouillée, empêchant toute sonnerie. On voit aussi sur la figure la roue de frappe 608 de 12 dents, dont la rotation décrite plus bas, permettra d'entraîner le marteau 90 afin de frapper les heures. Cette roue de frappe 608 se trouve à un autre niveau d'engrènement que le premier pignon de commande 705 ; contrairement à ce que la figure pourrait laisser croire, il n'y a jamais engrènement entre ces deux éléments.As seen, the axes 7 and 9 each carry a pinion, respectively 706 and 906 of each 12 teeth, continuously engaged together, making these two axes are simultaneously stationary or rotating. The axis 7 additionally carries a first control gear 705 provided here with 4 teeth out of 8, capable of being actuated by a wheel 3105, provided with 2 teeth in opposition, mounted on the axis 31. The axis 9 carries likewise a hammer lock cam 908 which, in its position shown in the figure, blocks the striking hammer 90 in the locked position, preventing any ringing. Also shown in the figure the knocking wheel 608 of 12 teeth, whose rotation described below, will drive the hammer 90 to hit the hours. This striking wheel 608 is at a different meshing level than the first control gear 705; contrary to what the figure might suggest, there is never any meshing between these two elements.

Tel que représenté sur les figures 3 et 4, de par la position de la bascule de commande 60, le dispositif de sonnerie est bloqué en position de non-sonnerie, la bascule de commande 60 étant verrouillée en position de non-sonnerie par son bras 62 en relation avec la came 907, bloquant ainsi la rotation du rouage, par la goupille du plateau 407 engagée par le bras 61, ainsi qu'en éloignant l'axe 8 par le bras 63, de manière à ce qu'aucune des roues portées sur cet axe ne puisse engrener avec une roue portée par l'axe 31. Par ailleurs, la position du premier pignon de commande 705 laisse passer les dents de la roue 3105 selon son mouvement d'incrémentations de 1/24ème de tour toutes les heures selon le sens horaire, décrit en regard de la figure 2. Dans cette position de la bascule de commande 60, on n'a donc aucune interaction entre le mouvement d'horlogerie lui-même et le dispositif de sonnerie.As shown on the figures 3 and 4 by the position of the control rocker 60, the striking device is locked in the non-ringing position, the control rocker 60 being locked in the non-ringing position by its arm 62 in relation to the cam 907, blocking thus the rotation of the train, by the pin of the plate 407 engaged by the arm 61, and by moving the axis 8 by the arm 63, so that none of the wheels carried on this axis can mesh with a wheel carried by the shaft 31. Furthermore, the position of the first drive gear 705 passes the teeth of the wheel 3105 along its movement increments of 1/24 of a turn every hour in the clockwise direction , described next to the figure 2 . In this position of the control rocker 60, there is therefore no interaction between the watch movement itself and the striking device.

La figure 5 montre les mêmes éléments que ceux de la figure 3, mais en position de début de sonnerie.The figure 5 shows the same elements as those of the figure 3 , but in the ring start position.

La bascule de commande 60 a pivoté d'une fraction de tour dans le sens horaire, sous l'action d'une commande de sonnerie de l'heure en cours fournie par le mouvement d'horlogerie 100 ou par une commande de sonnerie de l'heure en passant, fournie par un bouton poussoir sur le boîtier de la pièce d'horlogerie, ces deux commandes étant symbolisées par la flèche A sur la figure.The control flip-flop 60 has rotated a fraction of a turn clockwise, under the action of a current time ringing command provided by the watch movement 100 or by a ringing command of the clock. hour in passing, provided by a push button on the housing of the timepiece, these two commands being symbolized by the arrow A in the figure.

Lors de ce pivotement de la bascule 60, son bras 61 a libéré la goupille 41 du plateau 407, permettant ainsi aux roues et pignons 402, 502, 503, 603 et 803 de se mettre en rotation selon les sens indiqués par les flèches.During this pivoting of the rocker 60, its arm 61 has released the pin 41 of the plate 407, thus allowing the wheels and gears 402, 502, 503, 603 and 803 to rotate in the directions indicated by the arrows.

La rotation de la roue de marteau 603 entraîne le pignon de commande 703 qui pivote d'une portion de tour avant de s'arrêter vu qu'il n'a plus de dents en face de la roue 603. Les deux axes 7 et 9 pivotant simultanément comme vu précédemment par les pignons 706 et 906, l'axe 9 effectue de même un pivotement d'une portion de tour, amenant la came 907 en position comme représenté sur la figure, verrouillant ainsi la bascule 60 en position de sonnerie.The rotation of the hammer wheel 603 drives the control pinion 703 which pivots a portion of a turn before stopping since it has no more teeth in front of the wheel 603. The two axes 7 and 9 pivoting simultaneously as previously seen by the pinions 706 and 906, the axis 9 likewise rotates a portion of a turn, bringing the cam 907 into position as shown in the figure, thereby locking the latch 60 in the ringing position.

Le pivotement de la bascule 60 a encore déplacé l'axe 8, amenant la roue d'entraînement 804 en engrènement avec une roue 3104 montée sur l'axe 31, comme représenté sur la figure 6. On voit que la roue 3104 est maintenant entraînée en rotation selon le sens antihoraire alors qu'auparavant elle suivait la roue 3001 selon son mouvement d'incrémentation de 1/24 ème de tour toutes les heures, selon le sens horaire, comme décrit précédemment en regard de la figure 2.The pivoting of the rocker 60 has further moved the axis 8, bringing the drive wheel 804 into engagement with a wheel 3104 mounted on the shaft 31, as shown in FIG. figure 6 . It can be seen that the wheel 3104 is now rotated counterclockwise whereas previously it followed the wheel 3001 according to its movement. incrementation of 1 / 24th of a revolution every hour, in a clockwise direction, as described above with respect to the figure 2 .

La figure 7 montre les mêmes éléments que ceux de la figure 4, mais en position de début de sonnerie. Comme mentionné ci-dessus, les axes 7 et 9 ont pivoté d'une portion de tour puis se sont arrêtés, amenant le premier pignon de commande 705 en position prête à recevoir la dent de la roue 3105 en rotation selon le sens antihoraire entraînée selon le mouvement de la roue 3104 mentionné ci-dessus, alors que la came 908 a aussi pivoté d'une portion de tour, libérant le marteau 90. La roue de frappe 608 en rotation commande maintenant les coups de sonnerie du marteau 90.The figure 7 shows the same elements as those of the figure 4 , but in the ring start position. As mentioned above, the pins 7 and 9 have rotated a turn portion and then stopped, causing the first drive gear 705 to be in a position ready to receive the tooth of the wheel 3105 in a counter-clockwise rotation driven according to the movement of the wheel 3104 mentioned above, while the cam 908 has also rotated a portion of a turn, releasing the hammer 90. The knocking wheel 608 in rotation now controls the ringing of the hammer 90.

La figure 8 montre les mêmes éléments que ceux de la figure 7, mais en position de préparation de fin de sonnerie.The figure 8 shows the same elements as those of the figure 7 , but in the position of preparation of end of ring.

La roue 3105 a continué son mouvement de rotation dans le sens antihoraire de manière à ce qu'une de ses 2 dents arrive en prise avec le premier pignon de commande 705 et engrène avec ce dernier. Cet engrènement commande un pivotement de l'axe 7, puis de l'axe 9, via les pignons 706 et 906, décrits en regard de la figure 4. La came 908 est toujours en position de laisser le marteau 90 sonner les heures sous l'action de la roue de frappe 608.The wheel 3105 has continued to rotate counterclockwise so that one of its two teeth engages and meshes with the first drive gear 705. This meshing controls a pivoting of the axis 7, then of the axis 9, via the pinions 706 and 906, described with respect to the figure 4 . The cam 908 is still in the position to let the hammer 90 ring the hours under the action of the striking wheel 608.

La figure 9 montre que suite au mouvement de pivotement des axes 7 et 9 mentionné ci-dessus, le pignon 703 vient à nouveau en engrènement avec la roue 603, la rotation des axes 7 et 9 ainsi que des pignons et cames qu'ils portent étant maintenant commandée par ce dernier engrènement.The figure 9 shows that following the pivoting movement of the axes 7 and 9 mentioned above, the pinion 703 comes into meshing with the wheel 603, the rotation of the axes 7 and 9 and the gears and cams they are now being ordered by this last meshing.

La figure 10 est semblable à la précédente, juste un instant plus tard ; on y voit en particulier que le bras 62 de la bascule 60 va prochainement quitter la portion haute de la came 907 pour rejoindre sa portion en creux.The figure 10 is similar to the previous one, just a moment later; it is seen in particular that the arm 62 of the flip-flop 60 will soon leave the upper portion of the cam 907 to join its recessed portion.

La figure 11 montre les éléments de la figure 8 au même instant que celui représenté à la figure 10. Le premier pignon de commande 705 est maintenant dégagé de la roue 3105 et la came 908 est en position juste avant de bloquer le mouvement du marteau 90.The figure 11 shows the elements of the figure 8 at the same time as the one represented at figure 10 . The first drive gear 705 is now clear of the wheel 3105 and the cam 908 is in position just before blocking the movement of the hammer 90.

On comprend qu'a l'instant immédiatement suivant, le dispositif se trouve en même position que représentée aux figures 3 et 4, la came 907 maintenant la bascule 60 en position de non-sonnerie, soit éloigné l'axe 8 de l'axe 3, de manière à désengager la roue 804 de la roue 3104, et bloqué à nouveau le mouvement de rotation des axes 4, 5, 6 et 8 en engageant la goupille 41 du plateau 407 par son bras 61.It is understood that at the instant immediately following, the device is in the same position as shown in FIGS. figures 3 and 4 , the cam 907 maintaining the rocker 60 in the non-ringing position, is remote the axis 8 of the axis 3, so as to disengage the wheel 804 of the wheel 3104, and again blocked the rotational movement of the axes 4 , 5, 6 and 8 by engaging the pin 41 of the plate 407 by its arm 61.

Vu que la roue 3104 est maintenant hors d'engrènement, le moyen de positionnement schématisé par le ressort 32 représenté sur la figure 1, mais pouvant être un moyen magnétique, un moyen élastique comme par exemple un moyen à ressort comme un ressort spiral ou tout autre moyen mécanique permettant de ramener les roues 3104 et 3105 vers leur position de départ, soit indexée sur la roue 3001 d'où elles continuent leur mouvement d'incrémentation heure par heure. Lors de ce mouvement de retrait, la dent de la roue 3105 peut passer en face du pignon 705, de par la position de ce dernier.Since the wheel 3104 is now out of engagement, the positioning means schematized by the spring 32 shown in FIG. figure 1 but may be a magnetic means, an elastic means such as a spring means such as a spiral spring or any other mechanical means for bringing the wheels 3104 and 3105 to their starting position, is indexed on the wheel 3001 where they continue their incremental movement hour by hour. During this withdrawal movement, the tooth of the wheel 3105 can pass in front of the pinion 705, because of the position of the latter.

On comprend de ce qui précède que la durée pendant laquelle le marteau frappe les heures, respectivement le nombre de coups frappés est fonction de l'angle α représenté à la figure 7 correspondant au chemin que doit parcourir une dent de la roue 3105 entre le moment où la sonnerie est déclenchée, et celui où la came 907 repousse le bras 62 de la bascule 60 afin d'interrompre la sonnerie. Comme indiqué plus haut, cet angle augmente de 1/24ème de tour chaque heure. Le rapport d'engrenage entre la roue 3105 et la roue 608 est calculé de telle manière qu'un pivotement angulaire de 1/24ème de tour de la roue 3105 corresponde au passage d'une dent de la roue 608, respectivement à la frappe d'un coup de sonnerie.It is understood from the above that the duration during which the hammer strikes the hours, respectively the number of hits is a function of the angle α represented at the figure 7 corresponding to the path to be traveled by a tooth of the wheel 3105 between the moment when the ringing is triggered, and that where the cam 907 pushes the arm 62 of the rocker 60 to interrupt the ring. As noted above, this angle increases by 1/24 th of a turn every hour. The gear ratio between the wheel 3105 and the wheel 608 is calculated in such a way that an angular rotation of 1/24 th of a revolution of the wheel 3105 corresponds to the passage of a tooth of the wheel 608, respectively on strike a ringing sound.

Comme indiqué plus haut, la sonnerie peut être commandée soit par le mouvement d'horlogerie, auquel cas elle est commandée juste après que les roues 3001, 3104 et 3105 aient incrémenté d'un 24ème de tour, soit à la demande de l'utilisateur auquel cas le nombre de coups frappés correspond à l'heure passée.As indicated above, the buzzer can be controlled either by the watch movement, in which case it is controlled just after the wheels 3001, 3104 and 3105 have incremented by a 24 th of a turn, or at the request of the user, in which case the number of hits corresponds to the time passed.

Il est évident que de nombreuses variantes de construction peuvent être envisagée relativement à la forme d'exécution du dispositif de sonnerie décrit ci-dessus.It is obvious that many alternative constructions can be envisaged with respect to the embodiment of the striking device described above.

En particulier, la roue 101 a été décrite comportant une dent et effectuant 1 tour en 1 heure. Elle pourrait tout aussi bien comporter 12 dents et effectuer un tour en 12 heures ou n'importe quel nombre de dents, sa vitesse de rotation étant adaptée de manière à ce que la roue 3001, respectivement les axes 30 et 31 soient incrémentés de 1/24ème de tour toutes les heures. Cette roue 101, directement liée à l'affichage horaire, suit donc les réglages de cet affichage horaire, par exemple lors d'un passage de fuseau horaire ou lors d'un passage de l'heure d'hiver à l'heure d'été ou vice versa, modifiant ainsi directement l'angle α mentionné précédemment, réglant ainsi directement la sonnerie.In particular, the wheel 101 has been described having a tooth and performing 1 turn in 1 hour. It could equally well comprise 12 teeth and perform a revolution in 12 hours or any number of teeth, its rotational speed being adapted so that the wheel 3001, respectively the axes 30 and 31 are incremented by 1 / 24 th turn every hour. This wheel 101, directly related to the time display, therefore follows the settings of this time display, for example during a passage of time zone or during a transition from winter time to the time of day. summer or vice versa, thus directly modifying the angle α mentioned previously, thus directly adjusting the buzzer.

De même les axes 30 et 31 ont été décrits comme coaxiaux, on pourrait aussi bien avoir deux systèmes d'axe non coaxiaux, les moyens de positionnement 32 mentionnés pouvant comprendre un ou plusieurs pignons de liaison de manière à effectuer les opérations et fonctions décrites. En particulier, le découplage des axes 30 et 31, tel que décrit précédemment ou tel que proposé ci-dessus en variante, permet un réglage de sonnerie même lorsque celle-ci est en cours de sonnerie, sans endommagement d'aucune pièce du dispositif.Similarly the axes 30 and 31 have been described as coaxial, one could as well have two non-coaxial axis systems, the positioning means 32 mentioned may include one or more connecting gears so as to perform the operations and functions described. In particular, the decoupling of the axes 30 and 31, as previously described or as proposed above alternatively, allows a ring setting even when it is ringing, without damaging any part of the device.

De manière générale, les sens de rotation, nombres de pignons, de roues, nombres de dents décrits peuvent être adaptés selon les configurations rencontrées, de façon à remplir la ou les fonctions mentionnées. On voit donc que le dispositif de sonnerie comprend essentiellement des roues et pignons ; il est donc relativement simple de fabrication, facile à mettre au point, à régler et utiliser. Un tel dispositif est relativement moins onéreux qu'un dispositif correspondant à leviers et cames.In general, the directions of rotation, number of gears, wheels, numbers of teeth described can be adapted according to the configurations encountered, so as to fulfill the function or functions mentioned. It can be seen that the striking device essentially comprises wheels and gears; it is therefore relatively simple to manufacturing, easy to develop, adjust and use. Such a device is relatively less expensive than a device corresponding to levers and cams.
