Etat de la techniqueState of the art

Une pièce d'horlogerie répondant aux caractéristiques ci-dessus est déjà connue de l'état de la technique, s'agissant du modèle EMC de la maison Urwerk, présentée en 2013, et dont la construction a fait l'objet d'une protection par brevet, sous le numéro CH 707105 B1 .A timepiece meeting the above characteristics is already known from the state of the art, in the case of the EMC model from the house of Urwerk, presented in 2013, and the construction of which has been protected. by patent, under the number CH 707105 B1 .

Cette pièce d'horlogerie comporte un dispositif de mesure de la marche de son oscillateur mécanique comprenant un microphone, activé à la demande pour prendre une mesure, ainsi qu'un dispositif d'affichage de la valeur mesurée pour la marche de l'oscillateur directement sur la montre. Ainsi, cette pièce d'horlogerie présente un mouvement mécanique sophistiqué et fidèle aux traditions horlogères du haut-de-gamme, tout en proposant une évolution dans le domaine électronique n'intervenant pas dans le fonctionnement du mouvement mais permettant au porteur de la montre d'interagir avec ce dernier.This timepiece includes a device for measuring the rate of its mechanical oscillator comprising a microphone, activated on demand to take a measurement, as well as a device for displaying the measured value for the rate of the oscillator directly on the watch. Thus, this timepiece presents a sophisticated mechanical movement that is faithful to high-end watchmaking traditions, while proposing an evolution in the electronic field that does not intervene in the functioning of the movement but allows the wearer of the watch to 'interact with it.

Par la suite, les montres connectées, d'abord électroniques puis électromécaniques voire hybrides, c'est-à-dire connectées mais à mouvement mécanique et affichage par des organes d'affichage mécaniques, sont apparues sur le marché.Subsequently, connected watches, first electronic then electromechanical or even hybrid, that is to say connected but to mechanical movement and display by mechanical display members have appeared on the market.

Certains développements ont permis de tirer profit de l'intégration croissante de l'électronique dans les montres à mouvement mécanique.Certain developments have made it possible to take advantage of the increasing integration of electronics in watches with mechanical movements.

A titre d'exemple, la demande de brevet CH 711303 A1, déposée en 2015 , décrit une pièce d'horlogerie hybride comportant un module de communication sans fil permettant de commander certaines fonctions à distance, par exemple au moyen d'un smartphone. Ainsi, notamment, le smartphone peut être pourvu d'une application grâce à laquelle il peut effectuer une mesure de la marche de l'oscillateur mécanique depuis l'extérieur de sa boite. Puis, en fonction du résultat de cette mesure, l'application peut agir directement et automatiquement sur une raquette associée à l'oscillateur mécanique, par l'intermédiaire d'un moteur commandé, pour en modifier la position et ajuster la marche de l'oscillateur.For example, the patent application CH 711 303 A1, filed in 2015 , describes a hybrid timepiece comprising a wireless communication module making it possible to control certain functions remotely, for example by means of a smartphone. Thus, in particular, the smartphone can be provided with an application thanks to which it can measure the rate of the mechanical oscillator from outside its box. Then, depending on the result of this measurement, the application can act directly and automatically on a racket associated with the mechanical oscillator, via a controlled motor, to modify its position and adjust the speed of the oscillator.

L'intégration de composants électroniques dans les montres mécaniques a ouvert la voie vers un nombre important d'applications nouvelles possibles.The integration of electronic components in mechanical watches has paved the way for a large number of possible new applications.

Divulgation de l'inventionDisclosure of the invention

Un but principal de la présente invention est de proposer une construction alternative aux constructions déjà connues pour réaliser une pièce d'horlogerie à mouvement horloger mécanique dans laquelle l'intégration de composants électroniques est mise à profit pour proposer un niveau d'interaction élevé de l'utilisateur avec sa pièce d'horlogerie.A main aim of the present invention is to provide an alternative construction to the constructions already known for producing a timepiece with a mechanical watch movement in which the integration of electronic components is taken advantage of to provide a high level of interaction of the machine. user with his timepiece.

A cet effet, la présente invention concerne plus particulièrement une pièce d'horlogerie du type mentionné plus haut, caractérisée par le fait que la boite loge en outre un module de communication sans fil, susceptible d'échanger des données avec le dispositif de mesure de la marche de l'oscillateur mécanique et destiné à communiquer avec une unité électronique externe pour lui transmettre des résultats des mesures effectuées par le dispositif de mesure de la marche de l'oscillateur mécanique, à destination d'un utilisateur.To this end, the present invention relates more particularly to a timepiece of the type mentioned above, characterized in that the box also houses a wireless communication module, capable of exchanging data with the measuring device. the rate of the mechanical oscillator and intended to communicate with an external electronic unit to transmit to it the results of the measurements carried out by the device for measuring the rate of the mechanical oscillator, to a user.

De manière avantageuse mais non limitative, l'unité électronique externe peut être un téléphone portable de type smartphone ou une tablette, voire un ordinateur. De tels appareils électroniques sont devenus omniprésents dans le mode de vie de l'homme contemporain qui est habitué à s'en servir dans le cadre d'activités nombreuses et très diversifiées.Advantageously but not in a limiting manner, the external electronic unit can be a portable telephone of the smartphone or tablet type, or even a computer. Such electronic devices have become ubiquitous in the lifestyle of contemporary man who is used to using it in the context of many and very diverse activities.

Ainsi, grâce aux caractéristiques de la pièce d'horlogerie selon la présente invention, l'utilisateur peut recourir à un outil qui fait partie de son environnement habituel pour interagir avec sa pièce d'horlogerie et prendre connaissance des conditions de fonctionnement de son oscillateur mécanique. Toutefois, l'utilisation de ces moyens d'analyse électroniques modernes est ici associée à un mode d'action, par l'utilisateur, qui respecte la tradition horlogère puisque le réglage de la marche de l'oscillateur mécanique est réalisé de manière manuelle, par actionnement de l'organe de commande manuel. L'utilisateur peut alors prendre toute la mesure de l'impact de son intervention manuelle sur le mouvement horloger et de la délicatesse des réalisations horlogères, de manière générale.Thus, thanks to the characteristics of the timepiece according to the present invention, the user can use a tool which is part of his usual environment to interact with his timepiece and become aware of the operating conditions of his mechanical oscillator. . However, the use of these modern electronic analysis means is associated here with a mode of action, by the user, which respects the watchmaking tradition since the adjustment of the rate of the mechanical oscillator is carried out manually, by actuation of the manual control unit. The user can then take full measure of the impact of his manual intervention on the watch movement and of the delicacy of horological achievements, in general.

De manière préférée, on peut prévoir que le dispositif de mesure de la marche de l'oscillateur mécanique soit programmé pour prendre des mesures périodiques.Preferably, provision can be made for the device for measuring the rate of the mechanical oscillator to be programmed to take periodic measurements.

De manière alternative ou complémentaire, on peut prévoir que le dispositif de mesure de la marche de l'oscillateur mécanique soit agencé pour pouvoir effectuer au moins une mesure de la marche de l'oscillateur mécanique à la demande, en réponse à la réception d'un signal adapté par le module de communication sans fil, avant de transmettre en retour au module de communication sans fil au moins un signal représentatif du résultat obtenu pour la mesure effectuée.Alternatively or in addition, provision can be made for the device for measuring the rate of the mechanical oscillator to be designed to be able to perform at least one measurement of the rate of the mechanical oscillator on demand, in response to the reception of a signal adapted by the wireless communication module, before transmitting back to the wireless communication module at least one signal representative of the result obtained for the measurement carried out.

Ainsi, l'utilisateur souhaitant régler la marche de sa pièce d'horlogerie peut se baser sur une mesure récente de celle-ci avant d'actionner le mécanisme de réglage de la marche.Thus, the user wishing to adjust the rate of his timepiece can base himself on a recent measurement thereof before actuating the rate adjustment mechanism.

De plus, on peut prévoir que le dispositif de mesure de la marche de l'oscillateur mécanique soit agencé pour effectuer des mesures rapprochées pendant une durée prédéfinie en réponse à la réception d'un signal adapté par le module de communication sans fil, avant de transmettre en retour au module de communication sans fil au moins un signal représentatif du résultat obtenu pour chacune des mesures effectuées.In addition, provision can be made for the device for measuring the rate of the mechanical oscillator to be arranged to perform close measurements for a predefined period in response to the reception of an adapted signal by the wireless communication module, before transmit back to the wireless communication module at least one signal representative of the result obtained for each of the measurements carried out.

De manière avantageuse, on peut prévoir que les mesures rapprochées soient effectuées toutes les deux secondes, préférablement toutes les secondes, et que la durée prédéfinie soit comprise entre dix secondes et dix minutes, préférablement entre trente secondes et trois minutes.Advantageously, provision can be made for the close measurements to be carried out every two seconds, preferably every second, and for the predefined duration to be between ten seconds and ten minutes, preferably between thirty seconds and three minutes.

De manière générale, lorsque l'oscillateur mécanique comporte un échappement, on peut prévoir que le dispositif de mesure de la marche de l'oscillateur mécanique comporte un capteur agencé pour écouter les bruits de fonctionnement de l'échappement, pour en déduire la valeur de la marche de l'oscillateur mécanique.In general, when the mechanical oscillator comprises an escapement, provision can be made for the device for measuring the rate of the mechanical oscillator to include a sensor designed to listen to the operating noises of the escapement, in order to deduce therefrom the value of the march of the mechanical oscillator.

On peut également prévoir que le dispositif de mesure de la marche de l'oscillateur mécanique soit en outre agencé pour déterminer la valeur de l'amplitude des oscillations de l'oscillateur mécanique et/ou la valeur de son repère.Provision can also be made for the device for measuring the rate of the mechanical oscillator to be furthermore arranged to determine the value of the amplitude of the oscillations of the mechanical oscillator and / or the value of its reference mark.

Par ailleurs, de manière générale, lorsque la boite de la pièce d'horlogerie comporte une carrure et que l'oscillateur mécanique est associé à une raquette dont les déplacements entrainent une variation de la marche de l'oscillateur mécanique, on peut prévoir

  • que l'organe de commande manuel du mécanisme de réglage de la marche soit agencé au travers de la carrure de telle manière que sa rotation entraine la rotation d'un mobile denté de correction situé à l'intérieur de la boite, et
  • que le mobile denté de correction présente une liaison cinématique avec un mobile de raquetterie dont les mouvements de rotation entrainent des déplacements de la raquette.
Moreover, in general, when the case of the timepiece has a middle part and the mechanical oscillator is associated with a racket whose movements cause a variation in the rate of the mechanical oscillator, it is possible to provide
  • that the manual control member of the rate adjustment mechanism is arranged through the caseband in such a way that its rotation causes the rotation of a toothed correction wheel located inside the case, and
  • that the toothed correction mobile has a kinematic connection with a racket mobile whose rotational movements cause movements of the racket.

Dans ce cas, on peut également prévoir que la liaison cinématique comprenne un mobile intermédiaire présentant un premier secteur denté agencé en prise avec le mobile denté de correction et un deuxième secteur denté agencé en prise avec une denture du mobile de raquetterie.In this case, provision can also be made for the kinematic connection to include an intermediate mobile having a first toothed sector arranged in engagement with the toothed correction mobile and a second toothed sector arranged in engagement with a toothing of the racket mobile.

Mode(s) de réalisation de l'inventionMode (s) for carrying out the invention

La figure 1 représente un schéma illustrant le principe général de la pièce d'horlogerie selon la présente invention.The figure 1 represents a diagram illustrating the general principle of the timepiece according to the present invention.

La pièce d'horlogerie 1 est du type mécanique, c'est-à-dire ici qu'elle comporte un mouvement horloger comprenant un oscillateur mécanique et celle-ci peut être, indifféremment, à remontage manuel ou à remontage automatique sans impact sur la mise en œuvre de l'invention.The timepiece 1 is of the mechanical type, that is to say here that it comprises a horological movement comprising a mechanical oscillator and the latter can be, indifferently, with manual winding or with automatic winding without impact on the implementation of the invention.

Par ailleurs, il est prévu de munir la pièce d'horlogerie 1 d'un module électronique (non visible) destiné à présenter un certain nombre de fonctionnalités dont quelques-unes seront décrites dans la suite de la description. Le module électronique comprend notamment un module de communication sans fil (non visible) agencé de telle manière qu'il puisse échanger des données avec une unité électronique externe 2, illustrée sur la figure 1 sous la forme d'un téléphone portable du type smartphone. Tout autre type d'unité électronique externe adaptée pourra être utilisée sans sortir du cadre de l'invention, comme par exemple un appareil électronique dédié, une tablette ou un ordinateur. De même, le système d'exploitation installé sur l'unité électronique externe importe peu pour la mise en œuvre de l'invention. Quel que ce soit le système d'exploitation utilisé, l'unité électronique externe 2 est pourvue d'une application adaptée pour communiquer avec le module de communication sans fil de la pièce d'horlogerie 1.Furthermore, provision is made to provide the timepiece 1 with an electronic module (not visible) intended to present a certain number of functions, some of which will be described in the remainder of the description. The electronic module comprises in particular a wireless communication module (not visible) arranged in such a way that it can exchange data with an external electronic unit 2, illustrated on the figure. figure 1 in the form of a cell phone of the smartphone type. Any other type of suitable external electronic unit can be used without departing from the scope of the invention, such as for example a dedicated electronic device, a tablet or a computer. Likewise, the operating system installed on the external electronic unit is of little importance for the implementation of the invention. Whatever the operating system used, the external electronic unit 2 is provided with an application adapted to communicate with the wireless communication module of the timepiece 1.

Du point de vue du transfert de données sans fil, si la technologie Bluetooth (marque déposée) basse consommation est particulièrement adaptée à l'échange de données entre deux appareils comme ceux impliqués dans la mise en œuvre de la présente invention, d'autres technologies de transmission sans fil, comme par exemple le WiFi, pourront être mises en œuvre sans pour autant sortir du cadre de l'invention.From the point of view of wireless data transfer, if the low-power Bluetooth (registered trademark) technology is particularly suited to the exchange of data between two devices such as those involved in the implementation of the present invention, other technologies transmission, such as WiFi, for example, can be implemented without departing from the scope of the invention.

De manière générale, la pièce d'horlogerie 1 peut présenter l'apparence d'une pièce d'horlogerie mécanique conventionnelle suivant les fonctionnalités électroniques dont elle est pourvue, ou elle peut éventuellement présenter au moins un affichage dédié aux fonctions gérées par le module électronique.In general, the timepiece 1 can have the appearance of a conventional mechanical timepiece depending on the electronic functions with which it is provided, or it can optionally have at least one display dedicated to the functions managed by the electronic module. .

Dans tous les cas, la présente invention prévoit que le module électronique comprenne, ou soit associé à, un dispositif de mesure de la marche de l'oscillateur mécanique logé dans la boite de la pièce d'horlogerie 1. Ce dispositif de mesure peut être intégré directement dans le module électronique ou, en alternative, en être distinct.In all cases, the present invention provides that the electronic module comprises, or is associated with, a device for measuring the rate of the mechanical oscillator housed in the case of the timepiece 1. This measuring device can be integrated directly into the electronic module or, alternatively, be separate from it.

Ce dispositif de mesure de la marche de l'oscillateur mécanique peut être mis en œuvre de différentes manières connues sans grande incidence sur la présente invention, typiquement par utilisation d'un capteur acoustique ou d'un capteur optique, voire éventuellement d'une combinaison des deux, ou encore d'un capteur de champ magnétique.This device for measuring the rate of the mechanical oscillator can be implemented in various known ways without much impact on the present invention, typically by using an acoustic sensor or an optical sensor, or even possibly a combination. both, or a magnetic field sensor.

Pour des questions pratiques de simplification, le dispositif de mesure de la marche peut préférablement comporter un microphone agencé pour écouter les bruits de fonctionnement d'un échappement de l'oscillateur mécanique, de manière conventionnelle.For practical reasons of simplification, the device for measuring the rate may preferably include a microphone arranged to listen to the operating noises of an exhaust of the mechanical oscillator, in a conventional manner.

Le dispositif de mesure de la marche est préférablement apte à conduire une analyse des mesures réalisées pour déterminer la marche de l'oscillateur mécanique. On peut éventuellement prévoir que le dispositif de mesure de la marche déduise des informations supplémentaires des résultats des mesures, comme par exemple l'amplitude des oscillations de l'oscillateur mécanique ou encore son repère.The device for measuring the rate is preferably suitable for carrying out an analysis of the measurements made to determine the rate of the mechanical oscillator. Provision can optionally be made for the device for measuring the rate to deduce additional information from the results of the measurements, such as, for example, the amplitude of the oscillations of the mechanical oscillator or its reference mark.

Bien entendu, il est possible de prévoir, en alternative, qu'un module électronique de calcul, distinct du dispositif de mesure de la marche, soit agencé dans la pièce d'horlogerie 1 pour analyser les résultats des mesures réalisées par le dispositif de mesure de la marche.Of course, it is possible to provide, as an alternative, that an electronic calculation module, separate from the rate measuring device, is arranged in the timepiece 1 in order to analyze the results of the measurements made by the measuring device. a walk.

De manière générale, on peut prévoir que le dispositif de mesure de la marche soit programmé (ou commandé par un circuit de commande adapté) pour effectuer des mesures périodiques automatiques de la marche de l'oscillateur mécanique, par exemple une fois par heure ou une ou deux fois par jour.In general, provision can be made for the device for measuring the rate to be programmed (or controlled by a suitable control circuit) to perform automatic periodic measurements of the rate of the mechanical oscillator, for example once an hour or once per hour. or twice a day.

Toutefois, il peut être avantageux de prévoir que le dispositif de mesure de la marche effectue une mesure ou plusieurs mesures successives à la demande d'un utilisateur, par exemple en sélectionnant une fonction appropriée dans l'application, sur l'unité électronique externe 2.However, it may be advantageous to provide that the gait measuring device performs one measurement or several successive measurements at the request of a user, for example by selecting an appropriate function in the application, on the external electronic unit 2. .

Ainsi, par exemple, on peut prévoir un mode de fonctionnement de réglage de la marche dans lequel le dispositif de mesure de la marche est commandé pour effectuer des mesures rapprochées pendant une durée prédéfinie en réponse à la réception d'un signal adapté par le module de communication sans fil, avant de transmettre en retour au module de communication sans fil au moins un signal représentatif du résultat obtenu pour chacune des mesures effectuées. En particulier, on peut préférablement prévoir que les mesures rapprochées soient effectuées toutes les deux secondes, encore plus préférablement toutes les secondes, et que la durée prédéfinie soit comprise entre dix secondes et dix minutes, encore plus préférablement entre trente secondes et trois minutes.Thus, for example, there can be provided an operating mode for adjusting the rate in which the device for measuring the rate is controlled to take close measurements for a period of time. predefined in response to the reception of an adapted signal by the wireless communication module, before transmitting back to the wireless communication module at least one signal representative of the result obtained for each of the measurements carried out. In particular, provision may preferably be made for the close measurements to be taken every two seconds, even more preferably every second, and for the predefined duration to be between ten seconds and ten minutes, even more preferably between thirty seconds and three minutes.

Les résultats de ces mesures sont ensuite transmis à l'unité électronique externe 2 pour que l'utilisateur puisse prendre connaissance de la valeur de la marche de l'oscillateur mécanique et décider d'un éventuel intérêt à procéder à son réglage.The results of these measurements are then transmitted to the external electronic unit 2 so that the user can take note of the value of the rate of the mechanical oscillator and decide whether it is worthwhile to adjust it.

Les figures 2, 3 et 4 représentent différentes vues en perspective simplifiées d'une partie de la pièce d'horlogerie 1 selon la présente invention et de certains détails de construction de cette pièce d'horlogerie 1, illustrant comment l'utilisateur peut agir sur son oscillateur mécanique si les résultats des mesures de sa marche ne sont pas satisfaisants.The figures 2 , 3 and 4 show various simplified perspective views of part of the timepiece 1 according to the present invention and of certain construction details of this timepiece 1, illustrating how the user can act on his mechanical oscillator if the results of the measures of his walk are not satisfactory.

La pièce d'horlogerie 1 présente une construction globalement conventionnelle. Elle comporte une boite comprenant notamment une carrure 4 et un fond (non représenté), la carrure 4 portant des cornes 6 de fixation à un bracelet (non représenté) et étant traversée par une tige de remontage et de mise à l'heure solidaire d'une couronne 8 à son extrémité externe.The timepiece 1 has a generally conventional construction. It comprises a case comprising in particular a caseband 4 and a back (not shown), the caseband 4 carrying lugs 6 for attachment to a bracelet (not shown) and being traversed by a winding and time-setting rod integral with 'a crown 8 at its outer end.

Un mouvement horloger 10 de type mécanique est assemblé à la carrure 4 par l'intermédiaire d'un cercle d'encageage 12, le mouvement horloger 10 étant ici à remontage automatique, à titre illustratif non limitatif, comme l'indique la présence d'une masse 14 de remontage automatique.A watch movement 10 of the mechanical type is assembled to the caseband 4 by means of a casing ring 12, the watch movement 10 here being self-winding, by way of non-limiting illustration, as indicated by the presence of an automatic winding mass 14.

La base de temps du mouvement horloger 10 est fournie par un oscillateur mécanique 16 comprenant ici un balancier 18 associé à un ressort spiral 20 ainsi qu'à un échappement, dont la roue d'échappement 22 est partiellement visible sur la figure 2.The time base of the watch movement 10 is provided by a mechanical oscillator 16 comprising here a balance 18 associated with a spiral spring 20 as well as an escapement, the escape wheel 22 of which is partially visible on the figure 2 .

De manière connue, le balancier 18 est solidaire d'un arbre de balancier (non visible) dont une extrémité est pivotée dans un pont de balancier 24. Le pont de balancier 24 porte une raquette 26, assemblée à frottement gras de manière à pouvoir être pivotée sur le pont de balancier 24 pour ajuster la longueur utile du ressort spiral 20.In known manner, the balance 18 is integral with a balance shaft (not visible), one end of which is pivoted in a balance bridge 24. The balance bridge 24 carries a racket 26, assembled with greasy friction so as to be able to be pivoted on the balance bridge 24 to adjust the useful length of the spiral spring 20.

Il ressort plus particulièrement de la figure 3 que la raquette 26 présente une fourchette 28, positionnée au-dessus d'un bras du pont de balancier 24. Ce dernier porte en outre un mobile de raquetterie 30 susceptible de pivoter dans un trou du pont de balancier 24.It emerges more particularly from the figure 3 that the racket 26 has a fork 28, positioned above an arm of the balance bridge 24. The latter also carries a racket mobile 30 capable of pivoting in a hole in the balance bridge 24.

Le mobile de raquetterie 30 est également représenté, sur la figure 4, dans une vue depuis son côté opposé à celui visible sur la figure 3. Il comporte un tenon 32 portant une tête 34 à son extrémité libre, définissant une butée axiale pour une planche dentée 36, et dont l'autre extrémité 38 est logée dans le pont de balancier 24. Un disque 40 est chassé sur le tenon 32 de manière à être agencé en appui contre la planche dentée 36, le disque 40 étant décentré par rapport au tenon 32 et donc plus globalement par rapport à l'axe de rotation du mobile de raquetterie 30.The snowshoe mobile 30 is also represented, on the figure 4 , in a view from its side opposite to that visible on the figure 3 . It comprises a tenon 32 carrying a head 34 at its free end, defining an axial stop for a toothed board 36, and the other end 38 of which is housed in the balance bridge 24. A disc 40 is driven out on the tenon 32 of so as to be arranged to bear against the toothed board 36, the disc 40 being off-center with respect to the tenon 32 and therefore more generally with respect to the axis of rotation of the snowshoe mobile 30.

On comprend ainsi que le disque 40 est positionné entre les deux dents de la fourchette 28 en configuration assemblée, et qu'une rotation du mobile de raquetterie 30 entraine un déplacement, dans son plan, du disque 40, celui-ci agissant alors sur la fourchette 28 pour déplacer la raquette 26.It is thus understood that the disc 40 is positioned between the two teeth of the fork 28 in the assembled configuration, and that a rotation of the snowshoe mobile 30 causes a displacement, in its plane, of the disc 40, the latter then acting on the fork 28 to move the racket 26.

Le mobile de raquetterie 30 fait partie d'un mécanisme de réglage manuel de la marche de l'oscillateur mécanique 16 comportant par ailleurs un organe de commande 42 (voir sur la figure 2), agencé au travers de la carrure 4 pour être accessible depuis l'extérieur de la boite, un renvoi 44 portant un mobile denté de correction 46 et un mobile intermédiaire 48. Le mobile intermédiaire 48 est monté pivotant sur un élément de bâti du mouvement horloger 10 et présente un premier secteur denté 50 agencé en prise avec le mobile denté de correction 46, et un deuxième secteur denté 52 agencé en prise avec la denture de la planche dentée 36 du mobile de raquetterie 30.The snowshoe mobile 30 forms part of a manual adjustment mechanism for the rate of mechanical oscillator 16 further comprising a control member 42 (see figure 2 ), arranged through the middle part 4 to be accessible from outside the box, a return 44 carrying a toothed correction mobile 46 and an intermediate mobile 48. The intermediate mobile 48 is pivotally mounted on a frame element of the movement watchmaker 10 and has a first toothed sector 50 arranged in engagement with the toothed correction mobile 46, and a second toothed sector 52 arranged in engagement with the teeth of the toothed board 36 of the racket mobile 30.

L'organe de commande 42 est inséré dans un trou 54 de la carrure 4, dans lequel il est retenu par une vis 56 engagée dans une gorge 58 de l'organe de commande 42. Deux joints O-ring 60 sont engagés dans le trou 54, sur l'organe de commande 42, pour assurer à la fois l'étanchéité de l'ouverture correspondante dans la carrure 4 et la tenue de l'organe de commande 42 en rotation.The control member 42 is inserted into a hole 54 of the caseband 4, in which it is retained by a screw 56 engaged in a groove 58 of the control member 42. Two O-rings 60 are engaged in the hole 54, on the control member 42, to ensure both the sealing of the opening corresponding in the caseband 4 and the holding of the control member 42 in rotation.

L'organe de commande 42 présente un carré 62 à son extrémité interne destiné à être engagé dans un pignon 64 agencé en prise avec une roue du renvoi 44, pour pouvoir entrainer le mobile denté de correction 46 en rotation, en réponse à une rotation de l'organe de commande 42 par un utilisateur, dans un sens ou dans l'autre.The control member 42 has a square 62 at its internal end intended to be engaged in a pinion 64 arranged in engagement with a return wheel 44, in order to be able to drive the toothed correction wheel 46 in rotation, in response to a rotation of the control unit 42 by a user, in one direction or the other.

On notera qu'une découpe 66 adaptée dans le bâti du mouvement horloger 10 permet de définir des butées de limitation pour la rotation du mobile intermédiaire 48, de telle manière que ses secteurs dentés 50 et 52 ne puissent pas se dégager des dentures avec lesquelles ils coopèrent.It will be noted that a cutout 66 adapted in the frame of the watch movement 10 makes it possible to define limit stops for the rotation of the intermediate mobile wheel 48, in such a way that its toothed sectors 50 and 52 cannot disengage from the teeth with which they cooperate.

Grâce aux caractéristiques qui viennent d'être présentées, il apparait que l'utilisateur peut agir manuellement sur la raquette de sa pièce d'horlogerie pour ajuster la marche de son oscillateur mécanique, tout en ayant accès à la valeur de la marche en temps réel ou presque, selon les paramètres de fonctionnement retenus. Une mesure de la marche peut être demandée au besoin et/ou un mode de fonctionnement de réglage peut être activé consistant à prendre des mesures rapprochées pendant une certaine durée prédéfinie, suffisamment longue pour pouvoir modifier plusieurs fois la position de la raquette et vérifier l'impact de cette modification sur la valeur de la marche mesurée ensuite. Ainsi, l'utilisateur peut alterner lectures des mesures et actions manuelles pour modifier la position de la raquette aussi longtemps que le réglage de la marche de l'oscillateur mécanique n'est pas satisfaisant pour lui. Chaque utilisateur peut définir ses propres critères correspondant à un réglage satisfaisant. Typiquement, on peut estimer qu'un réglage de la marche est satisfaisant par exemple si sa valeur est comprise entre -1 seconde/jour et +5 secondes/jour, préférablement dans trois orientations perpendiculaires de la pièce d'horlogerie.Thanks to the characteristics which have just been presented, it appears that the user can act manually on the racket of his timepiece to adjust the rate of his mechanical oscillator, while having access to the value of the rate in real time. or almost, depending on the operating parameters selected. A gait measurement can be requested as needed and / or an adjustment mode of operation can be activated of taking close measurements for a certain predefined period of time, long enough to be able to change the position of the racket several times and check the position. impact of this modification on the value of the rate measured subsequently. Thus, the user can alternate readings of measurements and manual actions to modify the position of the racket as long as the adjustment of the rate of the mechanical oscillator is not satisfactory for him. Each user can define his own criteria corresponding to a satisfactory setting. Typically, one can estimate that a rate adjustment is satisfactory, for example if its value is between -1 second / day and +5 seconds / day, preferably in three perpendicular orientations of the timepiece.

On notera également que, grâce à l'intégration du dispositif de mesure de la marche de l'oscillateur mécanique directement dans la boite de la pièce d'horlogerie, il est possible de réaliser un suivi périodique sur le long terme de l'évolution de la valeur de la marche de l'oscillateur mécanique, ce qui permet d'effectuer un réglage plus fin si nécessaire.It will also be noted that, thanks to the integration of the device for measuring the rate of the mechanical oscillator directly in the case of the timepiece, it is possible to carry out periodic monitoring over the long term of the evolution of the value of the rate of the mechanical oscillator, which allows finer adjustment if necessary.

La présente invention propose donc un nouvel équilibre entre le respect de la tradition de l'horlogerie mécanique et l'utilisation des outils électroniques modernes, avec une approche à la fois ludique et permettant à l'utilisateur de mieux apprécier le fonctionnement de sa montre mécanique.The present invention therefore offers a new balance between respect for the tradition of mechanical watchmaking and the use of modern electronic tools, with an approach that is both fun and allowing the user to better appreciate the operation of his mechanical watch. .

La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple le fait que la pièce d'horlogerie illustrée soit une montre-bracelet, le mode d'implantation de l'organe de commande manuel dans la carrure ou la nature du mouvement horloger illustré et décrit. Le module électronique n'est pas illustré et n'a pas été décrit en détail étant donné qu'il peut présenter un grand nombre de fonctionnalités additionnelles non directement liées à la mise en œuvre de la présente invention. Le fonctionnement du module électronique est préférablement assuré par une pile ou une batterie rechargeable, non représentée, une batterie pouvant éventuellement être rechargée à partir des mouvements de la masse de remontage.The foregoing description attempts to describe a particular embodiment by way of nonlimiting illustration and the invention is not limited to the implementation of certain particular characteristics which have just been described, such as for example the fact that the illustrated timepiece is a wristwatch, the mode of implantation of the manual control member in the middle part or the nature of the illustrated and described watch movement. The electronic module is not illustrated and has not been described in detail given that it can have a large number of additional functionalities not directly linked to the implementation of the present invention. The operation of the electronic module is preferably provided by a rechargeable battery or battery, not shown, a battery possibly being recharged from the movements of the winding mass.

L'exemple de réalisation qui a été décrit permet à l'homme du métier de réaliser une grande variété de constructions de pièces d'horlogerie, du type comprenant un module de communication sans fil agencé pour transmettre des informations relatives à la marche de son oscillateur mécanique à une unité électronique externe, pour permettre à un utilisateur d'intervenir ensuite sur un mécanisme de réglage manuel de la marche de l'oscillateur mécanique, en fonction de ses propres besoins et sans sortir du cadre de la présente invention.The exemplary embodiment which has been described enables those skilled in the art to produce a wide variety of constructions of timepieces, of the type comprising a wireless communication module arranged to transmit information relating to the operation of its oscillator. mechanical to an external electronic unit, to allow a user to then intervene on a manual adjustment mechanism of the rate of the mechanical oscillator, according to his own needs and without departing from the scope of the present invention.
