Description

L'invention concerne les mouvements d'horlogerie comportant des mécanismes d'alarme ou de réveil, et en particulier de tels mouvements à remontage automatique comportant de tels mécanismes d'alarmes vibrantes, ces mouvements étant destinés à équiper des montres-bracelets, des montres de poche ou analogues.The invention relates to watch movements comprising alarm or alarm mechanisms, and in particular such self-winding movements comprising such vibrating alarm mechanisms, these movements being intended to equip wristwatches, watches and watches. pocket or the like.

Une montre bracelet commercialisée par la société Jaeger Lecoultre sous la référence « Master Grand Réveil » comprend un mécanisme de réveil permettant à une alarme de se déclencher automatiquement à un horaire prédéfini par l'utilisateur. Cette fonction réveil est assurée par un mécanisme relié au mouvement qui comprend un barillet indépendant, un système de réglage permettant de programmer l'heure de sonnerie, un système de déclenchement relié au rouage de finissage du mouvement et actionnant le réveil à l'heure prévue, et d'une sonnerie pour avertir le porteur. La sonnerie comprend d'une part un timbre sur lequel un marteau vient frapper afin de générer un signal sonore et d'autre part des moyens faisant vibrer la montre sans générer de signal sonore audible. Un commutateur permet de sélectionner le déclenchement soit d'une alarme sonore, soit d'une alarme silencieuse vibrante.A wristwatch sold by the company Jaeger Lecoultre under the reference "Master Grand Réveil" includes an alarm mechanism allowing an alarm to be triggered automatically at a predefined time by the user. This alarm function is provided by a mechanism connected to the movement which comprises an independent cylinder, an adjustment system for programming the time of ringing, a trigger system connected to the gear train of the movement and activating the alarm at the scheduled time , and a bell to warn the wearer. The ring comprises a first stamp on which a hammer is struck to generate an audible signal and secondly means vibrating the watch without generating an audible sound signal. A switch is used to select the triggering of either an audible alarm or a vibrating silent alarm.

Une telle montre présente cependant des inconvénients. En effet, le mécanisme de réveil nécessite une source d'énergie supplémentaire, et comprend des éléments spécifiques au mode de fonctionnement du mécanisme en mode d'alarme silencieuse qui augmente la complexité et l'encombrement de la structure. De plus l'amplitude de la vibration est limitée.Such a watch, however, has drawbacks. Indeed, the wakeup mechanism requires an additional source of energy, and includes elements specific to the operating mode of the mechanism in silent alarm mode that increases the complexity and bulk of the structure. In addition, the amplitude of the vibration is limited.

On connaît par ailleurs des montres utilisant un seul barillet pour l'actionnement d'un mouvement et la sonnerie d'une alarme, comme par exemple le brevet CH287622 , et également des dispositifs de sonnerie utilisant la masse oscillante comme timbre, comme dans le brevet CH330203 . Dans les deux cas toutefois l'alarme est toujours de type acoustique.Watches using a single barrel for the actuation of a movement and the ringing of an alarm, such as, for example, the patent are also known. CH287622 , and also ringing devices using the oscillating mass as a stamp, as in the patent CH330203 . In both cases, however, the alarm is always acoustic.

La présente invention a pour but principal de remédier à un ou plusieurs de ces inconvénients de l'art antérieur susmentionné en fournissant un mouvement d'horlogerie à remontage automatique utilisant avantageusement l'énergie stockée par le barillet d'un mouvement de base à remontage automatique pour actionner un mécanisme d'alarme.The main object of the present invention is to remedy one or more of these disadvantages of the abovementioned prior art by providing a self-winding watch movement advantageously using the energy stored by the barrel of a self-winding base movement. to operate an alarm mechanism.

La présente invention a également pour but de fournir un mouvement d'horlogerie à remontage automatique comportant un mécanisme d'alarme vibrante silencieuse utilisant avantageusement des éléments du mouvement et permettant de produire une vibration de forte amplitude.The present invention also aims to provide a self-winding clockwork movement comprising a silent vibrating alarm mechanism advantageously using elements of the movement and to produce a vibration of high amplitude.

Un autre but de l'invention est de fournir un mouvement d'horlogerie comprenant un tel dispositif d'alarme présentant une conception particulièrement simple et peu coûteuse à mettre en oeuvre dans le mouvement.Another object of the invention is to provide a watch movement comprising such an alarm device having a particularly simple and inexpensive design to implement in the movement.

A cet effet l'invention concerne un mouvement d'horlogerie 1 selon la revendication 1.For this purpose the invention relates to a clockwork movement 1 according to claim 1.

Le mécanisme d'alarme vibrante obtenu présente l'avantage d'être simplifié et de ne pas requérir de source d'énergie dédiée. Il en résulte un gain de place pour loger d'autres modules dans le boitier de la montre, comme par exemple un module chronographe, sans nécessiter d'augmentation du calibre de la montre. Par ailleurs, l'utilisation de la masse oscillante comme élément vibrant selon un mode de réalisation préférentiel de l'invention procure des vibrations d'une plus grande amplitude qu'avec un élément vibrant traditionnel, d'une part, et diminue d'autre part parallèlement le nombre de pièces à monter, tout comme le fait de réutiliser de nombreuses pièces du rouage de remontage, selon une autre variante préférentielle. Il en résulte un assemblage plus facile et une diminution des coûts de fabrication pour une montre comportant un tel mouvement.The vibrating alarm mechanism obtained has the advantage of being simplified and not requiring a dedicated energy source. This results in a saving of space to accommodate other modules in the case of the watch, such as a chronograph module, without requiring an increase in the caliber of the watch. Moreover, the use of the oscillating mass as a vibrating element according to a preferred embodiment of the invention provides vibrations of greater amplitude than with a traditional vibrating element, on the one hand, and decreases on the other hand. parallel to the number of parts to be assembled, just as the fact to reuse many parts of the winding train, according to another preferred embodiment. This results in easier assembly and lower manufacturing costs for a watch with such a movement.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description ci-après, en référence aux dessins annexés, dans lesquels:

  • la figure 1 est une vue de dessus du mouvement de la figure 1 formant une alarme vibrante selon un mode de réalisation préférentiel de l'invention, en coupe au niveau du pignon de masse;
  • la figure 2 est une vue de dessus du dispositif selon le mode de réalisation préférentiel de l'invention, avec la masse oscillante assemblée;
  • la figure 3 est une vue en coupe du dispositif selon la ligne III-III de la figure 2 ;
Other characteristics and advantages of the invention will emerge clearly from the description below, with reference to the appended drawings, in which:
  • the figure 1 is a top view of the movement of the figure 1 forming a vibrating alarm according to a preferred embodiment of the invention, in section at the ground pinion;
  • the figure 2 is a top view of the device according to the preferred embodiment of the invention, with the assembled oscillating weight;
  • the figure 3 is a sectional view of the device along line III-III of the figure 2 ;

La figure 1 représente une vue de dessus d'un mouvement d'horlogerie 1 d'une montre bracelet selon une variante préférentielle de l'invention. Le mouvement d'horlogerie 1 proposé associe un mécanisme d'alarme vibrante à un mouvement d'horlogerie comprenant un mécanisme de remontage automatique, connu en soi de l'homme du métier. Ce mécanisme de remontage automatique du mouvement 1 utilise la rotation d'une masse oscillante 2 - visible plus loin sur les figures 2 er 3 pour stocker de l'énergie mécanique dans un barillet 36 par l'intermédiaire d'un rouage 31,32,34 constituant une chaîne cinématique 3 qui engrène sur le pignon de masse 21 de la masse oscillante 2 - représentée sur la figure 2 - lequel forme une roue dentée. Grâce au décalage du centre de gravité de la masse oscillante 2 par rapport à son axe de rotation, qui est aussi celui du pignon de masse 21, les mouvements du poignet de l'utilisateur induisent une rotation de cette masse oscillante 2 par rapport au boîtier de la montre; cette rotation de la masse oscillante 2 entraîne celle de la roue à rochet 33 du barillet 36, à la sortie de la chaîne cinématique 3. La rotation de la roue à rochet 33 remonte le ressort à l'intérieur du barillet 36 et stocke ainsi de l'énergie mécanique qui sera distribuée vers un rouage de finissage 7, non représenté sur cette figure mais visible sur la figure 3, qui engrène sur les dents du barillet 36. Selon le mode de réalisation préférentiel illustré sur la figure 1, ce mécanisme de remontage est du type à remontage dans un seul sens, grâce à une roue inverseuse 31 classique, telle que décrite par exemple aux pages 35-37 de l'ouvrage « La montre Suisse à remontage automatique » de B. Humbert , et dont le fonctionnement sera expliqué plus loin. Les mobiles 32 et 34 sont des mobiles de réduction comportant chacun une roue et un pignon solidaires et coaxiaux, ils visent à établir un rapport d'engrenage adéquat pour ajuster la vitesse de rotation à obtenir à la sortie du rouage 3 en fonction de celle du pignon de masse 21. Les roues et pignons de tous les mobiles du rouage sont illustrés par la figure 3, qui permet de bien visualiser l'engrenage des différents éléments les uns sur les autres.The figure 1 represents a top view of a watch movement 1 of a wristwatch according to a preferred embodiment of the invention. The proposed clockwork movement 1 associates a vibrating alarm mechanism with a clockwork movement comprising an automatic winding mechanism, known per se to those skilled in the art. This mechanism of automatic winding movement 1 uses the rotation of an oscillating mass 2 - visible further on the figures 2 er 3 for storing mechanical energy in a barrel 36 via a gear train 31,32,34 constituting a kinematic chain 3 which meshes with the ground pinion 21 of the oscillating mass 2 - represented on the figure 2 which forms a toothed wheel. By shifting the center of gravity of the oscillating mass 2 relative to its axis of rotation, which is also that of the ground pinion 21, the wrist movements of the user induce a rotation of this oscillating mass 2 relative to the casing watch; this rotation of the oscillating mass 2 drives that of the ratchet wheel 33 of the barrel 36, at the output of the kinematic chain 3. The rotation of the ratchet wheel 33 raises the spring inside the barrel 36 and thus stores the mechanical energy that will be distributed to a work train 7, not shown in this figure but visible on the figure 3 which meshes with the teeth of the barrel 36. According to the preferred embodiment illustrated in FIG. figure 1 this winding mechanism is of the winding type in a single direction, thanks to a conventional inverting wheel 31, as described for example in FIGS. pages 35-37 of the book "The Swiss automatic watch" by B. Humbert , and whose operation will be explained later. The mobiles 32 and 34 are reduction mobiles each having a wheel and a pinion integral and coaxial, they are intended to establish a suitable gear ratio to adjust the speed of rotation to be obtained at the output of the train 3 according to that of the 21. The wheels and gears of all the moving parts of the wheel are illustrated by the figure 3 , which makes it possible to clearly visualize the gearing of the different elements on each other.

Comme représenté sur la figure 2, la masse oscillante 2 est montée à rotation sur un support 5 fixé à une platine 6, elle-même fixée dans le boîtier de la montre. La roue d'inversion 31 est également montée à rotation sur le support 5, qui présente des découpes adéquates de sorte que le pignon de masse 21 de la masse oscillante 2 s'engrène avec une première denture 311 de la roue d'inversion 31, tandis qu'une deuxième denture 312 de la roue d'inversion 31 s'engrène avec la roue du mobile de réduction 32. Ces premier et deuxième mobiles, non visibles sur la figure 2, sont visibles sur la figure 3. La roue d'inversion 31 forme une « roue libre » : dans un premier sens de rotation de la masse oscillante 2, la première denture du premier mobile 311 de la roue d'inversion 31 est accouplée à la deuxième denture du deuxième mobile 312 de cette roue d'inversion, alors que dans le deuxième sens de rotation de la masse oscillante 2, la première denture 311 de la roue d'inversion 31 est désaccouplée de la deuxième denture 312. La roue inverseuse consiste en un système à cliquet comprenant des tenons sur lesquels sont montés des bras 313 fixés sur le premier mobile 311, partiellement visibles sur la figure 1 et visibles également sur la vue en coupe de la figure 3 - tandis que des butées sont formées à la périphérie du deuxième mobile 312, qui est aussi solidaire d'un moyeu en étoile sur son axe de rotation. Les bras du cliquet 313 coopèrent avec le moyeu et les butées (non visibles sur la figure 1) de telle sorte qu'elles entraînent en rotation le deuxième mobile pour le sens de rotation S1 de la masse oscillante 2, et décliquètent dans le sens de rotation inverse S2.As shown on the figure 2 , the oscillating mass 2 is rotatably mounted on a support 5 fixed to a plate 6, itself fixed in the case of the watch. The reversing wheel 31 is also rotatably mounted on the support 5, which has adequate cutouts so that the ground pinion 21 of the oscillating mass 2 meshes with a first toothing 311 of the reversing wheel 31, while a second toothing 312 of the inversion wheel 31 meshes with the wheel of the reduction wheel 32. These first and second mobiles, not visible on the figure 2 , are visible on the figure 3 . The inversion wheel 31 forms a "free wheel": in a first direction of rotation of the oscillating mass 2, the first toothing of the first mobile 311 of the inversion wheel 31 is coupled to the second toothing of the second mobile 312 of this inversion wheel, while in the second direction of rotation of the oscillating mass 2, the first toothing 311 of the inversion wheel 31 is uncoupled from the second toothing 312. The inverting wheel consists of a ratchet system comprising tenons on which are mounted arms 313 fixed on the first mobile 311, partially visible on the figure 1 and also visible on the sectional view of the figure 3 - while stops are formed on the periphery of the second mobile 312, which is also integral with a star hub on its axis of rotation. The arms of the pawl 313 cooperate with the hub and the stops (not visible on the figure 1 ) such that they rotate the second mobile for the direction of rotation S1 of the oscillating mass 2, and declicker in the opposite direction of rotation S2.

Le mobile de réduction 32 engrenant avec la roue inverseuse 31 est monté à rotation par rapport au support 5 ; il comprend un pignon 322 et une roue de réduction 321, visibles tous deux sur la figure 3. La roue de réduction 321 s'engrène avec une roue 341 d'un autre mobile de réduction 34, aussi appelée roue entre-rochet, montée à rotation sur un pont 35 solidaire de la platine 6. La roue 341 engrène avec la roue à rochet 33 qui permet de remonter le ressort du barillet 36.The reduction gear 32 meshing with the inverting wheel 31 is rotatably mounted relative to the support 5; it comprises a pinion 322 and a reduction wheel 321, both visible on the figure 3 . The reduction wheel 321 meshes with a wheel 341 of another reduction wheel 34, also called a ratchet wheel, rotatably mounted on a bridge 35 secured to the plate 6. The wheel 341 meshes with the ratchet wheel 33 which makes it possible to raise the spring of the barrel 36.

Comme illustré sur la figure 3, qui constitue une coupe selon la ligne III-III de la figure 2, la roue à rochet 33 du barillet 36 est montée à rotation par rapport au pont 35, mais solidaire en rotation par rapport au moyeu du barillet 36, et qui engrène avec le pignon 342 du deuxième mobile de réduction 34 pour le remontage automatique du mouvement. Toutefois, un remontage manuel du barillet 36 est également possible par l'intermédiaire de la roue de remontage 371, qui engrène également avec la roue à rochet 33. La roue de remontage 371 est montée à rotation par rapport au pont 35 et peut être mise en rotation par l'utilisateur qui veut effectuer un remontage manuel de la montre par actionnement d'une tige ou d'une couronne munie d'une molette de préhension extérieure 372. L'énergie stockée dans le ressort (non illustré) du barillet 36 peut par conséquent être obtenue soit grâce à la rotation de la masse oscillante 2, soit par remontage manuel, le dispositif de remontage manuel 37 étant formé par la molette 372 et la roue de remontage 371. Cette dernière est cachée sur la figure 2 par la masse oscillante 2.As illustrated on the figure 3 , which constitutes a section along line III-III of the figure 2 , the ratchet wheel 33 of the barrel 36 is rotatably mounted relative to the bridge 35, but integral in rotation relative to the hub of the barrel 36, and which meshes with the pinion 342 of the second reduction gear 34 for the automatic winding of the movement . However, a manual winding of the barrel 36 is also possible via the winding wheel 371, which also meshes with the ratchet wheel 33. The winding wheel 371 is rotatably mounted relative to the bridge 35 and can be set in rotation by the user who wants to perform a manual winding of the watch by actuating a rod or a ring provided with an outer gripping wheel 372. The energy stored in the spring (not shown) of the barrel 36 can therefore be obtained either by the rotation of the oscillating weight 2 or by manual winding, the manual winding device 37 being formed by the wheel 372 and the winding wheel 371. The latter is hidden on the figure 2 by the oscillating mass 2.

Le mouvement 1 selon l'invention comprend également un mécanisme d'alarme vibrante, qui utilise la même source d'énergie 36 que celle du mouvement automatique 1, ainsi qu'une chaîne cinématique 4 pourvue d'un dispositif d'actionnement 41, visible sur les figures 1 et 2, et un élément vibrant 42. Le dispositif d'actionnement 41 du dispositif d'alarme vibrante est formé selon la variante illustrée par un cliquet 411 et un ressort 412 qui permettent de verrouiller le barillet 36 en rotation en dehors des horaires d'alarme grâce à la compression du cliquet 411 sur la denture d'un des mobiles du rouage 4 par l'intermédiaire du ressort 412, mais de libérer cette denture précisément lors du déclenchement de l'alarme à un horaire déterminé, de préférence réglable par l'utilisateur. Lorsque l'alarme se déclenche à un horaire prédéfini, le cliquet 411 pivote pour libérer la denture d'un des mobiles du rouage de la chaîne cinématique 4 et ainsi restituer l'énergie stockée dans le barillet 36. Un dispositif de commande, non représenté, permet de faire pivoter le cliquet 411 entre une position de verrouillage, en dehors de l'horaire l'alarme, et une position de dégagement durant l'horaire d'alarme.The movement 1 according to the invention also comprises a vibrating alarm mechanism, which uses the same energy source 36 as that of the automatic movement 1, as well as a kinematic chain 4 provided with an actuating device 41, visible on the figures 1 and 2 , and a vibrating element 42. The actuating device 41 of the vibrating alarm device is formed according to the variant illustrated by a pawl 411 and a spring 412 which make it possible to lock the barrel 36 in rotation outside the alarm times. at the compression of the pawl 411 on the toothing of one of the wheels of the wheel 4 via the spring 412, but to release this toothing precisely when the alarm is triggered at a fixed time, preferably adjustable by the user . When the alarm is triggered at a predefined time, the pawl 411 pivots to release the toothing of one of the moving wheels of the kinematic chain 4 and thus restore the energy stored in the barrel 36. A control device, not shown , makes it possible to rotate the pawl 411 between a locking position, outside the alarm time, and a release position during the alarm time.

Selon le mode de réalisation préférentiel illustré par les figures 1 à 3, l'élément vibrant 42 du mécanisme d'alarme vibrante est la masse oscillante 2. Cet élément est par conséquent référencé 2/42 sur les figures 2 et 3 pour indiquer que le même élément structurel correspond à deux éléments logiques distincts. Cette configuration permet de maximiser l'amplitude des vibrations sans requérir d'élément additionnel au mouvement, et ainsi économiser de la place. La masse oscillante 2 est tour à tour menante ou menée lorsqu'elle agit comme élément vibrant 42. L'élément vibrant 42 du mécanisme d'alarme vibrante, formé par la masse oscillante 2, est destiné à générer une vibration détectable au poignet de l'utilisateur; lorsque la montre repose sur une surface dure, les vibrations générées par le mécanisme d'alarme feront sautiller la montre ce qui provoquera un bruit lors des chocs avec cette surface.According to the preferred embodiment illustrated by the Figures 1 to 3 , the vibrating element 42 of the vibrating alarm mechanism is the oscillating mass 2. This element is therefore referenced 2/42 on the figures 2 and 3 to indicate that the same structural element corresponds to two distinct logical elements. This configuration makes it possible to maximize the amplitude of the vibrations without requiring additional element to the movement, and thus save space. The oscillating mass 2 is in turn driven or driven when it acts as a vibrating element 42. The vibrating element 42 of the vibrating alarm mechanism, formed by the oscillating mass 2, is intended to generate a detectable vibration at the wrist of the oscillator. 'user; when the watch rests on a hard surface, the vibrations generated by the alarm mechanism will make the watch skip which will cause a noise during shocks with this surface.

La source d'énergie utilisée pour alimenter le mécanisme d'alarme vibrante et le rouage de finissage 7, constituée par le barillet 36 commun aux deux chaînes cinématiques 3 et 4, est ici purement mécanique Toutefois, il est possible d'envisager une autre source d'énergie, par exemple électrique ou électromécanique, pour alimenter le dispositif d'alarme vibrante de l'invention, et/ou l'affichage normal de l'heure. Il est par exemple possible d'appliquer l'invention à un mécanisme de type ETA Autoquartz, dans lequel l'énergie mécanique de la masse oscillante est utilisée pour alimenter une génératrice, couplée à un accumulateur qui fournit de l'énergie électrique à un moteur de type Lavet.The energy source used to power the vibrating alarm mechanism and the finishing train 7, constituted by the barrel 36 common to the two kinematic chains 3 and 4, is here purely mechanical. However, it is possible to envisage another source. of energy, by electrical or electromechanical example, to supply the vibrating alarm device of the invention, and / or the normal display of the time. It is, for example, possible to apply the invention to an ETA Autoquartz type mechanism, in which the mechanical energy of the oscillating mass is used to power a generator, coupled to an accumulator which supplies electrical energy to an engine. Lavet type.

Selon le mode de réalisation préférentiel illustré sur les figures 1 à 3, les première et deuxième chaînes cinématiques 3,4 ont au moins un élément en commun en dehors du barillet 36. Selon la variante illustrée, tous les éléments de la chaîne cinématique 3, à savoir la roue inverseuse 31, et les roues de réduction 32,34 sont également communes à la chaîne cinématique 4 remontant du barillet 36 à la masse oscillante 2, qui est l'élément vibrant 42 du mécanisme d'alarme. En d'autres termes, selon le mode de réalisation illustré, les chaînes cinématiques 3 et 4 sont identiques, de telle sorte que tous les mobiles de la chaîne de remontage automatique peuvent être réutilisés par le mécanisme d'alarme vibrante sans requérir de mobile additionnel. On pourra toutefois remarquer que, contrairement à un mécanisme de remontage usuel, il n'y a pas de cliquet disposé sur la roue de couronne 37 afin de permettre le stockage de l'énergie dans le barillet 36. Ce cliquet a été remplacé par le cliquet 411, agissant ici sur la roue inverseuse 31, mais qui pourrait également agir, selon d'autres variantes non représentées, sur n'importe quel élément du rouage de la première chaîne cinématique 3 de remontage, comme par exemple la roue de rochet 33, ou l'une ou l'autre de roues de réduction 32,34. Le cliquet 411 selon l'invention a par conséquent une double vocation: hormis le déclenchement du mécanisme d'alarme vibrante, il agit sur le mécanisme de remontage pour permettre le stockage de l'énergie dans le barillet 36, et remplace ainsi un cliquet traditionnel de barillet.According to the preferred embodiment illustrated on the Figures 1 to 3 , the first and second drivelines 3.4 have at least one element in common outside the barrel 36. According to the variant shown, all the elements of the kinematic chain 3, namely the inverting wheel 31, and the reduction wheels 32 , 34 are also common to the drive train 4 going up from the barrel 36 to the oscillating weight 2, which is the vibrating element 42 of the alarm mechanism. In other words, according to the illustrated embodiment, the kinematic chains 3 and 4 are identical, so that all the mobile of the automatic winding chain can be reused by the vibrating alarm mechanism without requiring additional mobile . It may however be noted that, unlike a conventional winding mechanism, there is no pawl disposed on the crown wheel 37 in order to allow the energy to be stored in the barrel 36. This pawl has been replaced by the pawl 411, acting here on the inverting wheel 31, but which could also act, according to other variants not shown, on any element of the gear of the first kinematic chain 3 of winding, such as the ratchet wheel 33 , or either of the reduction wheels 32,34. The pawl 411 according to the invention therefore has a dual purpose: apart from the triggering of the vibrating alarm mechanism, it acts on the winding mechanism to allow the energy to be stored in the barrel 36, and thus replaces a traditional ratchet barrel.

Selon une variante préférentielle de l'invention, le mécanisme d'alarme vibrante qui utilise la même chaîne cinématique que celle du remontage du mouvement, entraîne la masse oscillante 2 formant l'élément vibrant 42 du mécanisme d'alarme dans le sens de rotation « libre », c'est-à-dire n'actionnant pas le remontage du mouvement. Lorsque l'énergie emmagasinée dans le barillet 36 est libérée par le cliquet 411, les éléments du rouage 31, 32, 33, 34 de la première chaîne cinématique 3 sont entraînés dans le sens inverse de celui observé lors du remontage du barillet par la masse oscillante 2 lorsque ces mêmes éléments sont considérés comme faisant partie de la deuxième chaîne cinématique 4. En effet, tandis que la première chaîne cinématique 3 actionne depuis le pignon de masse 21 la roue inverseuse 31, dont la rotation du premier mobile 311 entraîne celle du deuxième mobile 312, engrenant la première roue de réduction 32, puis la roue entre-rochet 34 et enfin la roue de rochet 33 pour remonter le ressort du barillet 36 pour un sens de rotation S1 du pignon de passe, la deuxième chaîne cinématique part de la roue de rochet 33 en sens inverse vers la roue entre-rochet 34 puis la roue de réduction 33 vers la roue inverseuse 31, qui entraîne cette fois le premier mobile 311 depuis le deuxième mobile 312 pour finalement engrener sur le pignon de masse 21, entraîné dans un sens de rotation S2 opposé à S1. La réflexion ci-dessus s'applique également à la roue de couronne 371, qui est entraînée dans un premier sens de rotation lors du remontage du mouvement 1 et dans un sens opposé lors que la roue de rochet 33 libère l'énergie du barillet vers l'éléments vibrant 42 formé par la masse oscillante 2.According to a preferred variant of the invention, the vibrating alarm mechanism that uses the same kinematic chain as that of the winding movement, causes the oscillating mass 2 forming the element. vibrating 42 of the alarm mechanism in the direction of rotation "free", that is to say not actuating the reassembly of the movement. When the energy stored in the barrel 36 is released by the pawl 411, the elements of the gear 31, 32, 33, 34 of the first kinematic chain 3 are driven in the opposite direction to that observed during the winding of the barrel by the mass. oscillating 2 when these same elements are considered as part of the second kinematic chain 4. Indeed, while the first kinematic chain 3 actuates from the ground pinion 21 the inverting wheel 31, the rotation of the first mobile 311 causes that of the second mobile 312, meshing the first reduction wheel 32, then the wheel between ratchet 34 and finally the ratchet wheel 33 to raise the spring of the barrel 36 for a direction of rotation S1 of the pinion gear, the second kinematic chain starts from the ratchet wheel 33 in the opposite direction to the wheel between the ratchet 34 and the reduction wheel 33 to the inverting wheel 31, which this time causes the first mobile 311 since the second mobile 312 to finally mesh with the pinion 21, driven in a direction of rotation S2 opposite to S1. The above reflection also applies to the crown wheel 371, which is driven in a first direction of rotation during the reassembly of the movement 1 and in an opposite direction when the ratchet wheel 33 releases the energy of the barrel towards the vibrating element 42 formed by the oscillating mass 2.

La vue en coupe du mouvement selon la figure 3, illustrant une variante préférentielle de l'invention selon laquelle les deux chaînes cinématiques 3 et 4 sont confondues, permet de mieux visualiser l'engrenage des différents éléments du rouage commun à ces deux chaînes cinématiques 3,4. On peut ainsi voir le rouage partant de la masse oscillante 2 et engrenant sur le premier mobile 311 de la roue inverseuse 31, qui entraîne le deuxième mobile 312 et le pignon 314 coaxial à ce deuxième mobile 312, qui lui-même engrène avec le mobile de réduction 32, dont le pignon 322 situé au dessus de la roue 321 engrenée entraîne en rotation la roue 341 du deuxième mobile de réduction 34, dont le pignon 342 inférieur engrène avec la roue à rochet. 33, laquelle remonte le ressort du barillet 36. L'énergie est libérée vers le rouage de finissage 7, tandis que le cliquet de retenue d'énergie dans le barillet 36, formé selon l'invention par le cliquet 411 de déclenchement du mécanisme d'alarme vibrante, n'est pas représenté, pour des questions de lisibilité. On distingue également la platine 6 sur laquelle sont placés tous les éléments du rouage ainsi que le pont 35 et le support 5 de la masse oscillante 2. Le même rouage 33, 342, 341, 322, 321, 314, 312, 311, 21 est utilisé en sens inverse depuis la roue de rochet 33 pour actionner la rotation de la masse oscillante agissant comme élément vibrant 42. La chaîne cinématique 4 permettant de transformer l'énergie du barillet 36 en rotation de la masse oscillante 2 remonte le même rouage 3 que celui utilisé pour le remontage du barillet 36. Il n'est ainsi pas nécessaire de placer un autre rouage partant de la denture du barillet 36 en série au rouage du finissage 7 pour le mécanisme d'alarme vibrante selon l'invention.The sectional view of the movement according to the figure 3 , illustrating a preferred variant of the invention according to which the two kinematic chains 3 and 4 are merged, makes it possible to better visualize the gearing of the different elements of the gear train common to these two kinematic chains 3,4. It is thus possible to see the train proceeding from the oscillating mass 2 and meshing with the first mobile 311 of the inverting wheel 31, which drives the second mobile 312 and the gear 314 coaxial with the second mobile 312, which itself meshes with the mobile reduction 32, the pinion 322 of which is located above the impeller 321 rotates the wheel 341 of the second reduction gear 34, the lower gear 342 meshes with the ratchet wheel. 33, which raises the spring of the barrel 36. The energy is released to the work train 7, while the energy retaining pawl in the barrel 36, formed according to the invention by the pawl 411 triggering the mechanism of vibrating alarm, not shown, for readability issues. We also distinguish the plate 6 on which are placed all the elements of the gear as well as the bridge 35 and the support 5 of the oscillating weight 2. The same wheel 33, 342, 341, 322, 321, 314, 312, 311, 21 is used in the opposite direction from the ratchet wheel 33 to actuate the rotation of the oscillating mass acting as a vibrating element 42. The kinematic chain 4 making it possible to transform the energy of the barrel 36 into rotation of the oscillating mass 2 goes back to the same wheel 3 that that used for the winding of the barrel 36. It is thus not necessary to place another gear from the teeth of the barrel 36 in series to the work train 7 for the vibrating alarm mechanism according to the invention.

La variante préférentielle du mouvement d'horlogerie selon l'invention contient de plus un dispositif de limitation de durée d'actionnement d'alarme 43, qui fixe un seuil maximal de prélèvement de l'énergie au barillet 36 alimentant à la fois le rouage de finissage 7 et le mécanisme d'alarme vibrante, de telle sorte que le déclenchement ce dernier n'ait pas d'influence néfaste sur le bon fonctionnement du mouvement en n'altérant pas ainsi sa réserve de marche de manière trop néfaste.The preferred variant of the watch movement according to the invention furthermore contains an alarm actuation duration limitation device 43, which sets a maximum energy picking threshold for the barrel 36 feeding both the gear train and the gearbox. finishing 7 and the vibrating alarm mechanism, so that the triggering of the latter has no adverse influence on the proper operation of the movement thus not altering its power reserve too damaging manner.

Comme illustré sur la figure 1, ce dispositif de limitation de durée d'actionnement d'alarme 43 comprend selon une variante préférentielle de l'invention une roue 432 qui engrène avec un des éléments de la deuxième chaîne cinématique 4, comme par exemple la roue de réduction 32, commune aux deux chaînes cinématiques 3,4 selon la variante illustrée, et un deuxième cliquet 431 qui engrène avec cette roue 432. Toutefois, lorsque le dispositif de limitation de durée d'actionnement d'alarme 43 engrène avec un élément commun à la chaîne cinématique de remontage 3 et la deuxième chaîne cinématique du mécanisme d'alarme vibrante 4, comme c'est le cas pour le mode de réalisation illustré, on doit s'assurer qu'il est inactif lors du remontage du barillet 36 par ladite masse oscillante 2 et bloquant lors du déclenchement de l'alarme. Ceci pourrait être réalisé par un agencement particulier du deuxième cliquet 431 et de l'encoche dans la roue 432, par exemple avec des formes obliques pour ne permettre l'encliquetage que dans un seul sens.As illustrated on the figure 1 , this alarm actuation duration limitation device 43 comprises, according to a preferred variant of the invention, a wheel 432 which meshes with one of the elements of the second kinematic chain 4, such as, for example, the reduction wheel 32, common to the two kinematic chains 3,4 according to the illustrated variant, and a second pawl 431 which meshes with this wheel 432. However, when the alarm actuation duration limitation device 43 meshes with a common element to the winding kinematic chain 3 and the second kinematic chain of the vibrating alarm mechanism 4, as is the case for the illustrated embodiment, it must be ensured that it is inactive during the winding of the barrel 36 by said oscillating mass 2 and blocking when triggering the alarm. This could be achieved by a particular arrangement of the second pawl 431 and the notch in the wheel 432, for example with oblique shapes to allow snapping only in one direction.

Un inconvénient du mécanisme de limitation selon la variante décrite ci-dessus est qu'il permet certes d'établir une borne supérieure de la durée d'alarme, mais jamais de borne inférieure. Il est ainsi tout à fait possible que le cliquet 431 se trouve très près de l'encoche lors du déclenchement de l'alarme, et que dans cette configuration l'alarme soit stoppée quasiment immédiatement après son déclenchement. C'est pourquoi, selon une variante non illustrée, la roue 432 pourrait également être constituée de deux mobiles couplés en rotation similairement à une roue inverseuse, le premier mobile étant solidaire de l'encoche dans laquelle viendrait se loger le cliquet 431, tandis que le deuxième mobile engrènerait avec un des éléments communs aux deux chaînes cinématiques 3,4, comme par exemple la roue de réduction 32. Si le mobile de la roue 432 engrenant avec les chaînes cinématiques est agencé de telle sorte qu'il décliquète lors du remontage du barillet 36, il sera alors entraînant lors de l'actionnement de l'alarme et il suffira de provoquer le décliquetage du cliquet 431 lors du déclenchement de l'alarme pour permettre le débloquage de la roue de limitation 432. De cette façon, la rotation de la roue de limitation 432 serait non seulement limitée, mais égale en permanence à une et une seule révolution complète de cette roue de limitation 432 lors du déclenchement de l'alarme. Ainsi, la durée de l'alarme serait identique pour chaque déclenchement d'alarme, la durée de l'alarme étant alors uniquement déterminée par le nombre de dents de la roue de limitation 432.A disadvantage of the limiting mechanism according to the variant described above is that it certainly allows to establish an upper limit of the alarm duration, but never lower limit. It is thus quite possible that the ratchet 431 is very close to the notch when the alarm is triggered, and that in this configuration the alarm is stopped almost immediately after it is triggered. Therefore, according to a variant not shown, the wheel 432 could also consist of two mobiles coupled in rotation similarly to an inverting wheel, the first mobile being secured to the notch in which the pawl 431 would be housed, while the second mobile unit would mesh with one of the elements common to the two kinematic chains 3,4, such as, for example, the reduction wheel 32. If the wheel of the wheel 432 meshing with the kinematic chains is arranged in such a way that it clicks during reassembly barrel 36, it will then be driving when actuating the alarm and it will suffice to cause the unclamping of the pawl 431 when triggering the alarm to allow the unlocking of the limitation wheel 432. In this way, the rotation of the limitation wheel 432 would not only be limited, but permanently equal to one and only one complete revolution of this limitation wheel 432 when triggering alarm. Thus, the duration of the alarm would be identical for each alarm trip, the duration of the alarm then being only determined by the number of teeth of the limitation wheel 432.

On pourrait ainsi configurer par ailleurs les rapports d'engrenage des différents éléments des chaînes cinématiques 3,4, en combinaison avec le mécanisme de limitation de durée de l'alarme 43 et en particulier le nombre de dents de la roue de limitation 432, de telle sorte que le fonctionnement de l'alarme soit limité à un tour de barillet 36 ou toute autre unité déterminée par l'homme du métier correspondant à une énergie suffisante pour générer des vibrations pendant une durée suffisante, de l'ordre d'une dizaine de secondes, sans pour autant vider indûment le barillet 36 en lui prélevant une énergie trop importante. Cette énergie peut également correspondre à une fraction de tour de barillet ou un nombre donné de tours de barillet, selon que le constructeur du mécanisme privilégie la durée de l'alarme au détriment de la réserve de marche restante. On pourra à cet effet considérer que l'utilisateur d'une montre munie d'un mécanisme d'alarme vibrante selon l'invention aura toujours tendance à remonter sa montre à chaque fin de mécanisme d'alarme, de telle sorte que même un arrêt de la montre après le déclenchement de l'alarme ne serait pas dommageable pour son utilisateur.It would thus be possible to configure the gear ratios of the various elements of the drivelines 3,4, in combination with the alarm duration limiting mechanism 43 and in particular the number of teeth of the limiting wheel 432, so that the operation of the alarm is limited to a barrel turn 36 or any other unit determined by the skilled in the art corresponding to sufficient energy to generate vibrations for a sufficient duration, of the order of ten seconds, without unduly emptying the barrel 36 by taking too much energy. This energy can also correspond to a fraction of a cylinder revolution or a given number of barrel turns, depending on whether the manufacturer of the mechanism favors the duration of the alarm at the expense of the remaining power reserve. It will be possible for this purpose to consider that the user of a watch provided with a vibrating alarm mechanism according to the invention will always tend to reassemble his watch at each end of the alarm mechanism, so that even a stop of the watch after the alarm is triggered would not be harmful to its user.

Selon ce mode de réalisation utilisant un mécanisme de limitation de durée de fonctionnement d'alarme 43, pour lequel on souhaite que le mécanisme ne soit actionné que pendant une durée correspondant à une seule rotation de la roue 432 de limitation, il serait nécessaire de coupler le deuxième cliquet 431 de limitation de la durée d'alarme au premier cliquet 411 de verrouillage du mécanisme d'alarme vibrante. En effet, si l'un ou l'autre de ces cliquets 411,431 n'est pas libéré, il sera impossible se restituer l'énergie du barillet 36 vers la masse oscillante 2 formant l'élément vibrant 42 du mécanisme d'alarme vibrante. Un tel couplage pourra être réalisé par une tige 44 solidaire des deux cliquets 411,431 représentée sur la figure 1. L'homme du métier comprendra toutefois que cette caractéristique de couplage pourra être réalisée indépendamment du choix de la durée maximale d'activation de l'alarme, en particulier si cette durée est simplement bornée mais pas nécessairement toujours égale, comme par exemple si la roue de limitation 432 n'est constituée que d'un seul mobile et avec un l'encliquetage asymétrique, c'est-à-dire passant pour le remontage du barillet 36 par la masse oscillante 2, mais bloquant pour l'enclenchement du mécanisme d'alarme vibrante dans le sens inverse de la même chaîne cinématique 3,4.According to this embodiment using an alarm operating duration limitation mechanism 43, for which it is desired that the mechanism be actuated only for a duration corresponding to a single rotation of the limiting wheel 432, it would be necessary to couple the second pawl 431 for limiting the alarm duration to the first locking pawl 411 of the vibrating alarm mechanism. Indeed, if one or the other of these pawls 411,431 is not released, it will be impossible to restore the energy of the barrel 36 to the oscillating mass 2 forming the vibrating element 42 of the vibrating alarm mechanism. Such coupling may be achieved by a rod 44 integral with the two pawls 411,431 shown in FIG. figure 1 . Those skilled in the art will however understand that this coupling characteristic can be achieved independently of the choice of the maximum duration of activation of the alarm, in particular if this duration is simply bounded but not necessarily always equal, as for example if the wheel 432 limitation is constituted by a single mobile and with an asymmetrical snap, that is to say passing for the winding of the barrel 36 by the oscillating mass 2, but blocking for the activation of the vibrating alarm mechanism in the opposite direction to the same kinematic chain 3,4.

L'homme du métier comprendra que les variantes décrites ci-dessus sont données à titre d'exemple et ne doivent en aucun cas être interprétées comme limitatives. L'invention concerne également une montre, par exemple une montre bracelet, comprenant un boîtier, et un mouvement d'horlogerie selon l'un des modes de réalisation décrits précédemment logé dans ledit boîtier.Those skilled in the art will understand that the variants described above are given by way of example and should in no way be interpreted as limiting. The invention also relates to a watch, for example a wristwatch, comprising a case, and a watch movement according to one of the previously described embodiments housed in said case.
