Definitions
- the present invention relates to the field of watchmaking and concerns a system for mechanically starting and stopping a function.
- starting the function we define the passage of the function, from an initial state, of rest, to a second state, active, and by stopping the function, we define the reverse passage from the active state to the state of rest.
- the present invention aims to propose a mechanism for controlling a function, which can be used in a mechanical watch, that is to say which does not use electronic or electrical elements, and which is remedied at least partially to the disadvantages of the prior art.
- the invention relates to a system for mechanically starting and stopping a function of a timepiece, comprising a mass, movably mounted on a frame, between a first and a second extreme positions, defined respectively by a first and a second stop, said mass moving, under the effect of gravity, by constraining a spring between the first and second extreme positions, and by relaxing said spring between the second and first extreme positions, said mass being connected kinematically or directly to a control member of said function.
- the mass and the force of the spring are determined as a function of the force necessary to control said function and move the control member, and the predetermined spatial orientations of the frame, in which the mass is moved in a bistable manner from one to the other. other of its extreme positions, depending on the result of the forces exerted by the spring and by gravity, the movement of the mass from the first extreme position to the second extreme position being capable of causing the starting or stopping of said function by via the control member, and the movement of the mass from the second extreme position to the first extreme position being capable of causing the stopping or starting respectively of said function via the control member. piloting.
- This definition of the invention extends to a system for controlling a function of a timepiece, capable of occupying a first state and a second state, in particular an animation.
- the invention also relates to a watch comprising such a starting and stopping system.
- the aim of the present invention is to provide a mechanical switch, making it possible to start and stop a function, on command, but without pressure or direct mechanical action on the switch. More precisely, the starting and stopping system according to the invention makes it possible to start and stop the function, according to the spatial orientation of the system and therefore of the watch in which it is integrated. As will be understood later, different dimensions are possible, but a preferred embodiment is to dimension and arrange the system according to the invention in such a way that the function starts when the wearer makes the usual gesture to read the time when the watch is on his wrist and the function stops when he rotates his wrist, for example to return his arm to a more vertical position.
- the system for starting and stopping a function comprises a mass, of the oscillating mass type, movably mounted on a watch frame, between a first and a second extreme positions.
- the latter are defined respectively by a first and a second stops, which can be elastic in order to absorb shocks.
- a spring is connected to the mass.
- the connection between the spring and the mass is preferably direct, so that the movements of the mass have a direct impact on the winding of the spring. More particularly, when the mass moves under the effect of gravity, following a gesture by the wearer which sets it in motion, the spring is arranged so as to be constrained by the mass when it moves between the first and the second extreme position. Conversely, when the mass moves between the second and first extreme positions, the spring relaxes and, if necessary, returns the energy stored in the mass, against gravity.
- the mass is connected kinematically or directly to a control member of said function.
- the connection between the mass and the control member is desmodromic.
- This connection can be of the meshing type with a pinion or a rack carried by the mass and meshing with the control member.
- the mass can also directly carry a magnet, which can magnetically control, for example, visual animation type functions as will be detailed below.
- the mass (of the mass) as well as the force of the spring are determined according to the force necessary to control said function and move the control member.
- the function is started when the wearer brings the watch to his or her gaze in a reading position.
- the alpha angle as being the angle of rotation around the axis 9H-3H
- the beta angle as being the angle of rotation around the axis 12H-6H
- the gamma axis as being l angle of rotation around the orthogonal axis passing through the center of the dial.
- the spring must also be dimensioned both in terms of its stiffness and its preload. Its function is to keep the mass abutting in its first extreme position, against gravity, until the watch has been placed in the corresponding orientation. Beyond this orientation, the force exerted by gravity is greater than the force exerted by the spring, and the mass moves starting the function.
- the spring also has the function, when the mass is abutted in its second extreme position, of returning the mass to its first extreme position when the force exerted by gravity becomes smaller than the force exerted by the spring. The mass then stops the function.
- a starting orientation and a stopping orientation are predetermined.
- the mass is of the bistable type and is maintained in its first extreme position as long as the watch has not crossed the starting orientation, and is maintained in its second extreme position as long as the watch has not crossed the starting orientation. 'stop.
- an oscillating mass of an automatic winder does not make it possible to stop the winding function.
- the winding and non-winding positions are not not predefined and do not correspond to specific spatial orientations of the watch.
- the ground can be connected to a speed regulator.
- the latter can be an escapement, for example with a rubbing rest as used in certain bells, or a brake with centrifugal weights, also of the type used in bells. It is also possible to use a magnetic or oil bath brake device.
- a ground blocking device can be provided.
- This device is advantageously accessible from outside the watch. It may consist of a pusher or a lock cooperating directly or indirectly with the mass to block its movements, preferably in one of its extreme positions.
- the system according to the invention could be arranged in the form of an independent module, comprising its own frame and mounted on a base movement.
- the mechanism or components making it possible to carry out the function to be controlled may also be arranged on the frame or be arranged on the basic movement.
- a kinematic or other connection, magnetic for example, will be provided between the module and the basic movement.
- the system according to the invention can be used to control, that is to say start and stop, a function whose mechanism which allows it to be carried out is arranged in the watch.
- An example of a function that can be controlled by the system according to the invention is a visual animation.
- the visual animation can be controlled mechanically, for example by releasing or blocking a barrel, respectively when the mass is in its first or second extreme positions.
- This barrel can drive an automaton, of the Jacquemart type, typically by driving a cam on which a mobile element is held pressed.
- this magnet By mounting a magnet on the mass or by having a magnet driven by the mass, this magnet can cause the movement of a paramagnetic or diamagnetic mobile element, capable of reacting to the movement of the magnet by moving itself. This movement can be guided by the mounting of said movable element, for example in rotation or on a guide rail.
- the function to be controlled is an animation, controlled by the movement of a magnet.
- the mass is an oscillating mass 10, mounted to move in rotation. It is provided with teeth 100, meshing with teeth 120 secured to the control member, which takes the form of a lever 12, pivotally mounted on the frame of the module or timepiece.
- the teeth 100 and 120 are advantageously incomplete, that is to say they are arranged on a toothed sector, less than 360°, given that the oscillating mass 10 is limited in its rotation between its two extreme positions, by two stops not shown. In the exemplary embodiment, the reduction ratio between the teeth is taken equal to -1.
- the spring 14 is of the spiral type, acting on the control member, according to the example at the level of the axis of rotation of the lever, by a first of its ends. The other end is fixed to the frame.
- the lever 12 at its end opposite its axis of rotation, carries a magnet 16.
- the latter acts on a magnetic, mobile element, movable for example above the dial, to be visible to a user, while the system of Start and stop is hidden under the dial.
- the spring 14 is preloaded, according to the example in a clockwise direction.
- the spring 14 will therefore apply a torque in the clockwise direction to the lever, transmitting to the oscillating mass 10, via the gear connection, a torque tending to make it pivot in the counterclockwise direction.
- the oscillating mass 10 is in its first extreme position, against a so-called high stop (not shown in the drawing).
- the system is therefore in equilibrium in a first stable position.
- the magnetic element positioned by the magnet is also in a first stable position. In this first position, it can be hidden behind a cover so as not to be visible to the wearer.
- Couple mass d * m * gravity * sinus alpha * cosine beta Beta being the angle (with a sign according to trigonometric standards) of the center of mass relative to the 9h-3h axis ( figure 2 )
- Couple Spring ⁇ K * Theta 0 + Beta 0 ⁇ Beta Beta0 being the Beta angle when the mass is in its first stable position.
- the alpha angle of the watch does not vary, only the Beta angle will change, and we will seek to ensure that the evolution of the torque generated by gravity increases faster than that of the spring (by choosing judiciously the different parameters of the mass and the spring).
- the torque only increases with the movement of the oscillating mass 10 and the passage from the first to the second extreme positions is carried out continuously, without passing through a stable intermediate position (without modification of the angle of the watch), and the mass is therefore bistable.
- the magnetic element is also in a second stable position. In this second position, it can be visible to the wearer.
- the oscillating mass 10 tends to rotate clockwise and therefore remains at a stop, in the second stable position.
- the function can also be a striking mechanism, the triggering of which can be repeated by a ringing in passing.
- the barrel is released or blocked depending on the positioning of the mass, respectively when it is in its first or second extreme positions.
- a winding mechanism either specific or via winding of the main barrel of the movement.
- This winding can be manual or automatic.
- the animation or ringing mechanism can also be powered by the movement barrel, using a barrel adapted to provide energy via two power take-offs.
- a kinematic connection with the unbalanced mass can also cause the movement of at least one movable flap on or under the main dial, a sub-dial or a part of the dial, to modify the appearance of the watch, or allow specific displays to appear.
- Polarized lenses can be used and moved via this movable shutter(s).
- Such shutters can also be moved by releasing a barrel, as described above.
- the system according to the invention makes it possible to control a function by starting and stopping it, or by controlling its passage from a first state to a second state, and vice versa, when the watch occupies respectively a first and a second spatial orientations.
- These particular spatial orientations correspond to first and second extreme positions of a mass. These positions are determined and thanks to the bistable nature of the movement of the mass, the transition from one state to another of the function is precise, corresponding to a specific spatial orientation.

Description
La présente invention se rapporte au domaine de l'horlogerie et concerne un système de démarrage et d'arrêt mécanique d'une fonction. Par démarrage de la fonction, on définit le passage de la fonction, d'un état initial, de repos, à un deuxième état, actif, et par arrêt de la fonction, on définit le passage inverse de l'état actif à l'état de repos.The present invention relates to the field of watchmaking and concerns a system for mechanically starting and stopping a function. By starting the function, we define the passage of the function, from an initial state, of rest, to a second state, active, and by stopping the function, we define the reverse passage from the active state to the state of rest.
Dans le domaine de l'horlogerie mécanique, on connait des fonctions qui présentent des états de repos ou d'arrêt et des états de fonctionnement. Par exemple, c'est le cas avec un chronographe, ou avec une répétition minute, qui sont actionnés par des poussoirs ou par une targette. Certaines fonctions sont également commandées automatiquement, par des systèmes complexes de déclenchement, comme également pour des sonneries au passage ou des réveils.In the field of mechanical watchmaking, we know functions which have rest or stop states and operating states. For example, this is the case with a chronograph, or with a minute repeater, which are operated by pushers or by a bolt. Certain functions are also controlled automatically, by complex trigger systems, such as ringtones or alarm clocks.

La présente invention a pour but de proposer un mécanisme de commande d'une fonction, qui soit utilisable dans une montre mécanique, c'est-à-dire qui ne fasse pas appel à des éléments électroniques ou électriques, et qui soit remédie au moins partiellement aux inconvénients de l'art antérieur.The present invention aims to propose a mechanism for controlling a function, which can be used in a mechanical watch, that is to say which does not use electronic or electrical elements, and which is remedied at least partially to the disadvantages of the prior art.
De façon plus précise, l'invention concerne un système de démarrage et d'arrêt mécanique d'une fonction d'une pièce d'horlogerie, comprenant une masse, montée mobile sur un bâti, entre une première et une deuxième positions extrêmes, définies respectivement par une première et une deuxième butées, ladite masse se déplaçant, sous l'effet de la gravité, en contraignant un ressort entre la première et la deuxième position extrêmes, et en détendant ledit ressort entre la deuxième et la première position extrêmes, ladite masse étant reliée cinématiquement ou directement à un organe de pilotage de ladite fonction.More precisely, the invention relates to a system for mechanically starting and stopping a function of a timepiece, comprising a mass, movably mounted on a frame, between a first and a second extreme positions, defined respectively by a first and a second stop, said mass moving, under the effect of gravity, by constraining a spring between the first and second extreme positions, and by relaxing said spring between the second and first extreme positions, said mass being connected kinematically or directly to a control member of said function.
La masse et la force du ressort sont déterminées en fonction de la force nécessaire pour commander ladite fonction et déplacer l'organe de pilotage, et des orientations spatiales prédéterminées du bâti, dans lesquelles la masse est déplacée de manière bistable de l'une à l'autre de ses positions extrêmes, selon la résultante des forces exercées par le ressort et par la gravité, le déplacement de la masse de la première position extrême à la deuxième position extrême étant apte à entraîner le démarrage ou l'arrêt de ladite fonction par l'intermédiaire de l'organe de pilotage, et le déplacement de la masse de la deuxième position extrême à la première position extrême étant apte à entraîner l'arrêt ou le démarrage respectivement, de ladite fonction par l'intermédiaire de l'organe de pilotage.The mass and the force of the spring are determined as a function of the force necessary to control said function and move the control member, and the predetermined spatial orientations of the frame, in which the mass is moved in a bistable manner from one to the other. other of its extreme positions, depending on the result of the forces exerted by the spring and by gravity, the movement of the mass from the first extreme position to the second extreme position being capable of causing the starting or stopping of said function by via the control member, and the movement of the mass from the second extreme position to the first extreme position being capable of causing the stopping or starting respectively of said function via the control member. piloting.
Cette définition de l'invention s'étend à un système de commande d'une fonction d'une pièce d'horlogerie, susceptible d'occuper un premier état et un deuxième état, notamment une animation.This definition of the invention extends to a system for controlling a function of a timepiece, capable of occupying a first state and a second state, in particular an animation.
Selon un autre aspect, l'invention concerne également une montre comprenant un tel système de démarrage et d'arrêt.According to another aspect, the invention also relates to a watch comprising such a starting and stopping system.

Le but de la présente invention est de proposer un interrupteur mécanique, permettant de démarrer et d'arrêter une fonction, sur commande, mais sans pression ou action mécanique directe sur l'interrupteur. Plus précisément, le système de démarrage et d'arrêt selon l'invention, permet de démarrer et d'arrêter la fonction, selon l'orientation spatiale du système et donc de la montre dans laquelle il est intégré. Comme on le comprendra par la suite, différents dimensionnements sont possibles, mais un mode de réalisation préféré est de dimensionner et d'agencer le système selon l'invention de manière à ce que la fonction démarre lorsque le porteur effectue le geste habituel pour lire l'heure lorsque la montre est à son poignet et que la fonction cesse lorsqu'il effectue une rotation du poignet, par exemple pour remettre son bras dans une position plus verticale.The aim of the present invention is to provide a mechanical switch, making it possible to start and stop a function, on command, but without pressure or direct mechanical action on the switch. More precisely, the starting and stopping system according to the invention makes it possible to start and stop the function, according to the spatial orientation of the system and therefore of the watch in which it is integrated. As will be understood later, different dimensions are possible, but a preferred embodiment is to dimension and arrange the system according to the invention in such a way that the function starts when the wearer makes the usual gesture to read the time when the watch is on his wrist and the function stops when he rotates his wrist, for example to return his arm to a more vertical position.
Plus particulièrement, le système de démarrage et d'arrêt d'une fonction selon l'invention, comprend une masse, de type masse oscillante, montée mobile sur un bâti de montre, entre une première et une deuxième positions extrêmes. Ces dernières sont définies respectivement par une première et une deuxième butées, pouvant être élastiques afin d'amortir les chocs.More particularly, the system for starting and stopping a function according to the invention comprises a mass, of the oscillating mass type, movably mounted on a watch frame, between a first and a second extreme positions. The latter are defined respectively by a first and a second stops, which can be elastic in order to absorb shocks.
Un ressort est relié à la masse. La liaison entre le ressort et la masse, est de préférence directe, de sorte que les déplacements de la masse ont directement une incidence sur l'armage du ressort. Plus particulièrement, lorsque la masse se déplace sous l'effet de la gravité, suite à un geste du porteur qui la met en mouvement, le ressort est agencé de manière à être contraint par la masse lorsqu'elle se déplace entre la première et la deuxième position extrêmes. A l'inverse, lorsque la masse se déplace entre la deuxième et la première position extrêmes, le ressort se détend et, le cas échéant, restitue l'énergie emmagasinée à la masse, à l'encontre de la gravité.A spring is connected to the mass. The connection between the spring and the mass is preferably direct, so that the movements of the mass have a direct impact on the winding of the spring. More particularly, when the mass moves under the effect of gravity, following a gesture by the wearer which sets it in motion, the spring is arranged so as to be constrained by the mass when it moves between the first and the second extreme position. Conversely, when the mass moves between the second and first extreme positions, the spring relaxes and, if necessary, returns the energy stored in the mass, against gravity.
La masse est reliée cinématiquement ou directement à un organe de pilotage de ladite fonction. De manière avantageuse, la liaison entre la masse et l'organe de pilotage, est desmodromique. Cette liaison peut être de type engrènement avec un pignon ou une crémaillère portée par la masse et engrenant avec l'organe de pilotage. La masse peut également porter directement un aimant, qui peut piloter magnétiquement, par exemple des fonctions de type animations visuelles comme on le détaillera ci-après.The mass is connected kinematically or directly to a control member of said function. Advantageously, the connection between the mass and the control member is desmodromic. This connection can be of the meshing type with a pinion or a rack carried by the mass and meshing with the control member. The mass can also directly carry a magnet, which can magnetically control, for example, visual animation type functions as will be detailed below.
La masse (de la masse) ainsi que la force du ressort sont déterminées en fonction de la force nécessaire pour commander ladite fonction et déplacer l'organe de pilotage. On dimensionne également le système en fonction des orientations angulaires prédéterminées de la montre, dans lesquelles la masse est déplacée de l'une à l'autre de ses positions extrêmes, selon la résultante des forcées exercées par le ressort et par la gravité, le déplacement de la masse de l'une à l'autre desdites positions extrêmes entraînant le démarrage, respectivement l'arrêt de ladite fonction par l'intermédiaire de l'organe de pilotage.The mass (of the mass) as well as the force of the spring are determined according to the force necessary to control said function and move the control member. We also dimension the system according to the predetermined angular orientations of the watch, in which the mass is moved from one to the other of its extreme positions, according to the result of the forces exerted by the spring and by gravity, the movement of the mass from one to the other of said extreme positions causing the starting or stopping of said function via the control member.
En d'autres termes, on détermine dans un premier temps la force ou le couple nécessaire pour démarrer, respectivement arrêter la fonction (pour faire pivoter des navettes ou une roue à colonne de chronographe, actionner un levier de déclenchement, déplacer un aimant...).In other words, we first determine the force or torque necessary to start or stop the function (to rotate shuttles or a chronograph column wheel, activate a trigger lever, move a magnet, etc.). .).
On détermine également les orientations de la montre dans lesquelles on souhaite que la fonction soit démarrée, respectivement arrêtée. Dans un mode de réalisation préféré, on détermine que la fonction est démarrée lorsque le porteur amène la montre à son regard dans une position de lecture. Comme on peut le voir sur la
De préférence, mais sans que ce soit obligatoire, on veut également arrêter la fonction dans une position de rotation du poignet qui soit différente de la position précédente. On limite ainsi le risque d'alternance intempestive entre des arrêts et des démarrages, autour d'une orientation unique. De préférence, l'orientation d'arrêt est définie pour Alpha compris entre 15-18°, Beta =0°, Gamma=0°. On relèvera que l'orientation d'arrêt est, de préférence, différente de l'orientation neutre du point de départ pris en considération pour le démarrage (dans lequel Alpha = 0°, Beta =0°, Gamma=0°). On pourra jouer sur cette hystérésis dans le calcul du ressort, pour différencier les orientations de la montre utilisées respectivement pour le démarrage et l'arrêt de la fonction. Cette différenciation permet d'éviter des alternances intempestives de démarrage et d'arrêt, que l'on pourrait avoir si la montre oscillait autour d'une position unique de déclenchement et d'arrêt.Preferably, but without it being obligatory, we also want to stop the function in a wrist rotation position which is different from the previous position. This limits the risk of untimely alternation between stops and starts, around a single orientation. Preferably, the stop orientation is defined for Alpha between 15-18°, Beta =0°, Gamma=0°. It will be noted that the stopping orientation is preferably different from the neutral orientation of the starting point taken into consideration for starting (in which Alpha = 0°, Beta = 0°, Gamma = 0°). We can play on this hysteresis in the calculation of the spring, to differentiate the orientations of the watch used respectively for starting and stopping the function. This differentiation makes it possible to avoid unwanted alternations of start and stop, which could occur if the watch oscillated around a single start and stop position.
A partir de ces facteurs, on détermine la course de la masse, la masse (de la masse) pour générer le couple nécessaire.From these factors, we determine the travel of the mass, the mass (of the mass) to generate the necessary torque.
Toutefois, on doit également dimensionner le ressort tant au niveau de sa raideur que de sa précontrainte. Sa fonction est de maintenir la masse en butée dans sa première position extrême, à l'encontre de la gravité, tant que la montre n'a pas été mise dans l'orientation correspondante. Au-delà de cette orientation, la force exercée par la gravité est plus grande que la force exercée par le ressort, et la masse se déplace en démarrant la fonction. Le ressort a également la fonction, lorsque la masse est en butée dans sa deuxième position extrême, de ramener la masse dans sa première position extrême lorsque la force exercée par la gravité devient plus petite que la force exercée par le ressort. La masse arrête alors la fonction.However, the spring must also be dimensioned both in terms of its stiffness and its preload. Its function is to keep the mass abutting in its first extreme position, against gravity, until the watch has been placed in the corresponding orientation. Beyond this orientation, the force exerted by gravity is greater than the force exerted by the spring, and the mass moves starting the function. The spring also has the function, when the mass is abutted in its second extreme position, of returning the mass to its first extreme position when the force exerted by gravity becomes smaller than the force exerted by the spring. The mass then stops the function.
Le dimensionnement et les calculs de la masse, et des caractéristiques du ressort sont à la portée de l'homme du métier, sans devoir les décrire en détails. Pour obtenir le résultat escompté, plusieurs solutions de paramètres existent, par exemple avec une masse plus lourde, et un ressort plus fort, le système peut être déclenché et arrêté selon le cahier des charges demandé.The sizing and calculations of the mass and characteristics of the spring are within the reach of those skilled in the art, without having to describe them in detail. To obtain the expected result, several parameter solutions exist, for example with a heavier mass, and a stronger spring, the system can be triggered and stopped according to the requested specifications.
On pourra avoir recours à une masse balourdée montée mobile en rotation, à l'instar d'une masse oscillante de remontage automatique, dont certaines fonctionnent selon une course angulaire limitée. Dans ce cas, on prendra en compte le balourd, qui inclut l'excentricité de la masse, qui a un effet sur le couple fourni. Cependant, la masse peut également avoir une trajectoire linéaire ou complexe.We could use an unbalanced mass mounted to move in rotation, like an automatic winding oscillating mass, some of which operate with a limited angular stroke. In this case, we will take into account the unbalance, which includes the eccentricity of the mass, which has an effect on the torque supplied. However, the mass can also have a linear or complex trajectory.
Ainsi, on prédétermine une orientation de démarrage et une orientation d'arrêt. La masse est de type bistable et est maintenue dans sa première position extrême tant que la montre n'a pas franchi l'orientation de démarrage, et est maintenue dans sa deuxième position extrême tant que la montre n'a pas franchi l'orientation d'arrêt.Thus, a starting orientation and a stopping orientation are predetermined. The mass is of the bistable type and is maintained in its first extreme position as long as the watch has not crossed the starting orientation, and is maintained in its second extreme position as long as the watch has not crossed the starting orientation. 'stop.
A la différence de la présente invention, une masse oscillante d'un remontoir automatique, ne permet pas d'arrêter la fonction de remontage. En tout état de cause, même si on devait considérer que dans certaines positions de la masse, notamment quand elle est à l'arrêt, il n'y a pas de remontage du barillet, les positions de remontage et de non-remontage ne sont pas prédéfinies et ne correspondent pas à des orientations spatiales spécifiques de la montre.Unlike the present invention, an oscillating mass of an automatic winder does not make it possible to stop the winding function. In any case, even if we were to consider that in certain positions of the mass, notably when it is stationary, there is no winding of the barrel, the winding and non-winding positions are not not predefined and do not correspond to specific spatial orientations of the watch.
Afin de réduire les chocs liés aux déplacements de la masse et aux interactions avec les butées, la masse peut être connectée à un régulateur de vitesse. Ce dernier peut être un échappement, par exemple à repos frottant comme utilisé dans certaines sonneries, ou un frein à masselottes centrifuges, également du type utilisé dans les sonneries. On pourra également utiliser un dispositif de frein magnétique ou à bain d'huile.In order to reduce shocks linked to mass movements and interactions with the stops, the ground can be connected to a speed regulator. The latter can be an escapement, for example with a rubbing rest as used in certain bells, or a brake with centrifugal weights, also of the type used in bells. It is also possible to use a magnetic or oil bath brake device.
Pour offrir à l'utilisateur la possibilité de shunter l'interrupteur et de bouger la montre sans lancer la fonction, on pourra prévoir un dispositif de blocage de la masse. Ce dispositif est avantageusement accessible depuis l'extérieur de la montre. Il peut consister en un poussoir ou un verrou coopérant directement ou indirectement avec la masse pour bloquer ses déplacements, de préférence dans une de ses positions extrêmes.To offer the user the possibility of shunting the switch and moving the watch without starting the function, a ground blocking device can be provided. This device is advantageously accessible from outside the watch. It may consist of a pusher or a lock cooperating directly or indirectly with the mass to block its movements, preferably in one of its extreme positions.
Le système selon l'invention pourra être agencé sous forme d'un module indépendant, comprenant son propre bâti et monté sur un mouvement de base. Le mécanisme ou les composants permettant de réaliser la fonction à commander pourront également être agencés sur le bâti ou être disposés sur le mouvement de base. Dans ce cas, une liaison cinématique ou autre, magnétique par exemple, sera prévue entre le module et le mouvement de base.The system according to the invention could be arranged in the form of an independent module, comprising its own frame and mounted on a base movement. The mechanism or components making it possible to carry out the function to be controlled may also be arranged on the frame or be arranged on the basic movement. In this case, a kinematic or other connection, magnetic for example, will be provided between the module and the basic movement.
Le système selon l'invention pourra être utilisé pour commander, c'est-à-dire démarrer et arrêter, une fonction dont le mécanisme qui permet de la réaliser, est agencé dans la montre.The system according to the invention can be used to control, that is to say start and stop, a function whose mechanism which allows it to be carried out is arranged in the watch.
Un exemple de fonction pouvant être pilotée par le système selon l'invention, est une animation visuelle. L'animation visuelle peut être commandée mécaniquement, par exemple en libérant ou en bloquant un barillet, respectivement lorsque la masse est dans sa première ou dans sa deuxième positions extrêmes. Ce barillet peut entraîner un automate, de type jacquemart, typiquement en entraînant une came sur laquelle est maintenu appuyé un élément mobile. En montant un aimant sur la masse ou en ayant un aimant entraîné par la masse, cet aimant peut entraîner le déplacement d'un élément mobile paramagnétique ou diamagnétique, susceptible de réagir au déplacement de l'aimant en se déplaçant lui-même. Ce déplacement pourra être guidé, par le montage dudit élément mobile, par exemple en rotation ou sur un rail de guidage.An example of a function that can be controlled by the system according to the invention is a visual animation. The visual animation can be controlled mechanically, for example by releasing or blocking a barrel, respectively when the mass is in its first or second extreme positions. This barrel can drive an automaton, of the Jacquemart type, typically by driving a cam on which a mobile element is held pressed. By mounting a magnet on the mass or by having a magnet driven by the mass, this magnet can cause the movement of a paramagnetic or diamagnetic mobile element, capable of reacting to the movement of the magnet by moving itself. This movement can be guided by the mounting of said movable element, for example in rotation or on a guide rail.
A la
La masse est une masse oscillante 10, montée mobile en rotation. Elle est munie d'une denture 100, en prise, avec une denture 120 solidaire de l'organe de pilotage, qui prend la forme d'un levier 12, monté pivotant sur le bâti du module ou de la pièce d'horlogerie. Les dentures 100 et 120 sont avantageusement incomplètes, c'est-à-dire qu'elles sont disposées sur un secteur denté, inférieur à 360°, étant donné que la masse oscillante 10 est limitée dans sa rotation entre ses deux positions extrêmes, par deux butées non représentées. Dans le mode de réalisation en exemple, le rapport de réduction entre les dentures est pris égal à -1.The mass is an
Le ressort 14 est de type spiral, agissant sur l'organe de pilotage, selon l'exemple au niveau de l'axe de rotation du levier, par une première de ses extrémités. L'autre extrémité est fixée au bâti.The
Le levier 12, à son extrémité opposée à son axe de rotation, porte un aimant 16. Ce dernier agit sur un élément magnétique, mobile, déplaçable par exemple au-dessus du cadran, pour être visible à un utilisateur, tandis que le système de démarrage et d'arrêt est caché sous le cadran.The
Lorsque la montre est en position horizontale, la gravité est parallèle à l'axe de rotation de la masse. De ce fait, le balourd de la masse ne génère aucun couple au niveau de l'axe.When the watch is in a horizontal position, gravity is parallel to the axis of rotation of the mass. As a result, the unbalance of the mass does not generate any torque at the axis.
De plus, le ressort 14 est précontraint, selon l'exemple dans le sens horaire. Le ressort 14 va donc appliquer un couple dans le sens horaire au levier, transmettant à la masse oscillante 10, via la liaison d'engrenage, un couple tendant à la faire pivoter dans le sens anti-horaire. Cependant dans cette position, la masse oscillante 10 est dans sa première position extrême, contre une butée dite haute (non représentée sur le dessin). Le système est donc en équilibre dans une première position stable. L'élément magnétique positionné par l'aimant est également dans une première position stable. Dans cette première position, il peut être caché derrière un cache pour ne pas être visible du porteur.In addition, the
Quand le porteur de la montre la fait tourner selon l'axe 9H-3H (
Le couple du ressort de rappel (ramené au centre de rotation de la masse) est constant tant que Beta reste le même et sa valeur est :
Il existe également un couple résistif pour faire passer la fonction d'un état arrêté à un état démarré. On va considérer ce couple comme étant constant dans notre exemple (de valeur Cresistif) et opposé au sens de déplacement.There is also resistive torque to move the function from a stopped state to a started state. We will consider this couple as being constant in our example (of Cresistif value) and opposite to the direction of movement.
L'équilibre des couples appliqués à la masse est donc :
Tant que ce couple est négatif, la masse tend à tourner dans le sens anti-horaire et donc reste en butée, dans la première position stable.As long as this torque is negative, the mass tends to rotate counterclockwise and therefore remains at a stop, in the first stable position.
Ce couple devient positif quand sinus (Alpha) devient plus grand que (beta=beta0) :
Une fois que la résultante des couples appliqués à la masse oscillante 10, est devenue positive, le couple généré par la gravité va être plus grand que le couple résistif de la fonction et du ressort de rappel. La masse va donc pivoter autour de son axe, dans le sens horaire (Beta va diminuer). La masse oscillante 10 va rester en mouvement tant qu'elle n'a pas atteint sa deuxième position extrême (
En pratique si l'angle alpha de la montre ne varie pas, seul l'angle Beta va changer, et on va chercher à ce que l'évolution du couple généré par la gravité, augmente plus vite que celui du ressort (en choisissant judicieusement les différents paramètres de la masse et du ressort). De la sorte, une fois la masse mise en mouvement, le couple ne fait qu'augmenter avec le déplacement de la masse oscillante 10 et le passage de la première à la deuxième des positions extrêmes est effectué en continu, sans passer par une position intermédiaire stable (sans modification de l'angle de la montre), et la masse est donc bistable. L'élément magnétique est également dans une deuxième position stable. Dans cette deuxième position, il peut être visible du porteur.In practice if the alpha angle of the watch does not vary, only the Beta angle will change, and we will seek to ensure that the evolution of the torque generated by gravity increases faster than that of the spring (by choosing judiciously the different parameters of the mass and the spring). In this way, once the mass is set in motion, the torque only increases with the movement of the
Tant que l'angle de la montre reste inchangé, le système reste en équilibre avec la masse oscillante 10 dans sa deuxième position stable. L'équation des couples a cependant changé car le couple résistif de la fonction a maintenant changé de signe (pour faire passer la fonction cette fois d'un état démarré, à un état arrêt), la masse devant tourner dans le sens anti horaire).As long as the angle of the watch remains unchanged, the system remains in balance with the
On a :
Tant que ce couple sera positif, la masse oscillante 10 tend à tourner dans le sens horaire et donc reste en butée, dans la deuxième position stable.As long as this torque is positive, the oscillating
Ce couple devient négatif quand sinus (Alpha) devient plus petit que (beta =betaF) :
Une fois que la résultante des couples appliqués à la masse, est devenue négative, le couple généré par la gravité va être plus petit que le couple résistif de la fonction et du ressort de rappel. La masse oscillante 10 va donc pivoter autour de son axe, dans le sens anti-horaire (Beta va augmenter). La masse va rester en mouvement tant qu'elle n'est pas revenue à sa première position extrême ou que le couple généré par la gravité redevient plus grand que les couples résistifs.Once the result of the torques applied to the mass has become negative, the torque generated by gravity will be smaller than the resistive torque of the function and the return spring. The oscillating
En pratique si l'angle de la montre ne varie pas, seul e va changer, et on va chercher à ce que l'évolution du couple généré par la gravité, diminue plus vite que celui du ressort (en choisissant judicieusement les différents paramètres de la masse et du ressort). De la sorte, une fois la masse mise en mouvement, le couple ne fait que diminuer avec le déplacement de la masse et le passage de la deuxième à la première des positions extrêmes est effectué en continu, sans passer par une position intermédiaire stable (sans modification de l'angle de la montre), et la masse est donc bien bistable.In practice if the angle of the watch does not vary, only e will change, and we will seek to ensure that the evolution of the torque generated by gravity decreases more quickly than that of the spring (by choosing judiciously the different parameters of mass and spring). In this way, once the mass is set in motion, the torque only decreases with the movement of the mass and the passage from the second to the first extreme positions is carried out continuously, without passing through a stable intermediate position (without modification of the angle of the watch), and the mass is therefore bistable.
On notera que dans le cas d'une animation visuelle, les notions d'arrêt et de démarrage de la fonction doivent s'entendre de manière large, comme correspondant à un premier et un deuxième état de l'animation visuelle. A toutes fins utiles, on pourra utiliser le terme de système de commande, comme équivalent au terme de système de démarrage et d'arrêt.It should be noted that in the case of a visual animation, the notions of stopping and starting the function must be understood broadly, as corresponding to a first and a second state of the visual animation. For all practical purposes, we can use the term control system, as equivalent to the term start and stop system.
A l'instar de l'animation visuelle entraînée par un barillet, la fonction peut également être un mécanisme de sonnerie, dont le déclenchement peut être repris d'une sonnerie au passage. Le barillet est libéré ou bloqué au gré du positionnement de la masse, respectivement lorsqu'elle est dans sa première ou dans sa deuxième positions extrêmes.Like the visual animation driven by a barrel, the function can also be a striking mechanism, the triggering of which can be repeated by a ringing in passing. The barrel is released or blocked depending on the positioning of the mass, respectively when it is in its first or second extreme positions.
Dans les deux exemples précités mettant en oeuvre un barillet, celui-ci est remonté par un mécanisme de remontage, soit spécifique soit via le remontage du barillet principal du mouvement. Ce remontage peut être manuel ou automatique. On peut également alimenter le mécanisme d'animation ou de sonnerie par le barillet du mouvement, en utilisant un barillet adapté pour fournir de l'énergie par deux prises de force.In the two aforementioned examples using a barrel, it is wound by a winding mechanism, either specific or via winding of the main barrel of the movement. This winding can be manual or automatic. The animation or ringing mechanism can also be powered by the movement barrel, using a barrel adapted to provide energy via two power take-offs.
Par une liaison cinématique de type engrenage (pignon ou crémaillère), on peut également déplacer des roues ou pignon, comme par exemple un jeu de navettes ou une roue à colonne de chronographe, en tant qu'organe de pilotage du chronographe. La phase de remise à zéro pourra être avantageusement effectuée par un poussoir agissant de manière séparée sur l'organe de pilotage et sur les éléments conventionnels de remise à zéro (marteaux ...).By a kinematic connection of gear type (pinion or rack), it is also possible to move wheels or pinions, such as for example a set of shuttles or a chronograph column wheel, as a control member of the chronograph. The reset phase can advantageously be carried out by a pusher acting separately on the control member and on the conventional reset elements (hammers, etc.).
Une liaison cinématique avec la masse balourdée peut également entraîner le déplacement d'au moins un volet mobile sur ou sous le cadran principal, d'un sous-cadran ou d'une partie de cadran, pour modifier l'apparence de la montre, ou laisser apparaître des affichages particuliers. Des verres polarisés peuvent être utilisés et déplacés via ce ou ces volets mobiles.A kinematic connection with the unbalanced mass can also cause the movement of at least one movable flap on or under the main dial, a sub-dial or a part of the dial, to modify the appearance of the watch, or allow specific displays to appear. Polarized lenses can be used and moved via this movable shutter(s).
De tels volets peuvent également être déplacés par la libération d'un barillet, à l'instar de ce qui a été décrit ci-dessus.Such shutters can also be moved by releasing a barrel, as described above.
Ainsi, le système selon l'invention permet de commander une fonction en la démarrant et en l'arrêtant, ou en commandant son passage d'un premier état à un deuxième état, et réciproquement, lorsque la montre occupe respectivement une première et une deuxième orientations spatiales. Ces orientations spatiales particulières correspondent à des première et deuxième positions extrêmes d'une masse. Ces positions sont déterminées et grâce au caractère bistable du déplacement de la masse, le passage d'un état à un autre de la fonction, est précis, correspondant à une orientation spatiale spécifique.Thus, the system according to the invention makes it possible to control a function by starting and stopping it, or by controlling its passage from a first state to a second state, and vice versa, when the watch occupies respectively a first and a second spatial orientations. These particular spatial orientations correspond to first and second extreme positions of a mass. These positions are determined and thanks to the bistable nature of the movement of the mass, the transition from one state to another of the function is precise, corresponding to a specific spatial orientation.
L'homme du métier pourra adapter le descriptif ci-dessus, sans sortir du cadre de l'invention défini dans les revendications. Il pourra définir les orientations de démarrage et d'arrêt, les types et forces et précontraintes de ressort, la liaison entre la masse et le système de pilotage.Those skilled in the art will be able to adapt the above description, without departing from the scope of the invention defined in the claims. It will be able to define the starting and stopping orientations, the types and forces and spring preloads, the connection between the mass and the control system.
