Definitions
- the invention relates to a watch movement for a mechanical watch, comprising, arranged on a plate, a resonator mechanism and an exhaust mechanism subjected to the pair of motor means that comprises said movement, said resonator mechanism comprising an inertial element arranged to oscillate with respect to said plate, said inertial element being subjected to the action of elastic return means fixed directly or indirectly to said plate, and said inertial element being arranged to cooperate with an escape wheel that includes said exhaust mechanism and which pivots around a main axis.
- the invention also relates to a mechanical watch comprising at least one such movement.
- the invention relates to the field of resonator mechanisms constituting the time bases of mechanical watches.
- the exhaust mechanism must be strong, shock-resistant, and designed to avoid pinching the movement (overturning).
- a mechanical resonator combines at least one inertial element and an elastic return element.
- the spiral acts as an elastic return element for the inertial element that constitutes the balance.
- the Swiss lever escapement has a low fuel efficiency (about 30%). This low performance comes from the fact that the movements of the exhaust are jerky, that there are “falls” (path lost to accommodate machining errors) and, also, that several components are transmitted their movement via inclined planes that rub against each other.
- a watchmaking mechanism comprises, mounted mobile, at least pivotally relative to a plate, an arranged escape wheel to receive a motor torque via a train, and a first oscillator having a first rigid structure connected to this plate by first elastic return means.
- This regulating mechanism comprises a second oscillator, which comprises a second rigid structure, which is connected to the first rigid structure by second elastic return means, and which comprises guide means arranged to cooperate with complementary guide means that includes the escape wheel, synchronizing the first oscillator and the second oscillator with the wheel.
- This clock oscillator comprises coupling means for the interaction of the primary resonators, comprising motor means for driving a mobile in motion which comprises driving and guiding means arranged to drive and guide an articulated control means with means for transmission each articulated, remote control means, with a mass of a primary resonator, and the primary resonators and the mobile are arranged such that the axes of the joints of any two of the primary resonators and the axis of articulation of the control means are never coplanar.

- the invention proposes a resonator in which the elastic return element also constitutes the guide, as well as mechanisms architectures allowing continuous interactions, without saccade, between resonator and escape wheel. To do this, we must concede the use of at least a second degree of freedom of the resonator, the second degree of freedom being out of phase with the first. So that the resonator is not sensitive to gravity or to shocks in translation, two degrees of freedom in rotation are chosen, the axes of which pass through the center of mass of the inertial element.

The above equation ensures, in steady state, a circular trajectory of this finger 21 with respect to the pivot axis of the escapement wheel 4.
- the invention more particularly relates to a watch movement 500 for a mechanical watch 1000.
- This movement 500 comprises, arranged on a plate 1, a resonator mechanism 100 and an escapement mechanism 200 subjected to the pair of motor means 300 that includes the movement 500.

- the first axis D1 and the second axis D2 are perpendicular to each other and perpendicular to the main axis D.
- the elastic return means 3, 31, 32 constitute cardan-type guiding means and are arranged to prohibit the movement of the center of inertia G of the inertial element 2 according to the three linear degrees of freedom and to a degree of freedom in rotation, so as to allow the mobility of the inertial element 2 only in two degrees of freedom in rotation, around the first axis D1 and of the second axis D2, and around a central point constituting a fixed position of the center of inertia G with respect to the plate 1.

Description
L'invention concerne un mouvement d'horlogerie pour une montre mécanique, comportant, agencés sur une platine, un mécanisme résonateur et un mécanisme d'échappement soumis au couple de moyens moteurs que comporte ledit mouvement, ledit mécanisme résonateur comportant un élément inertiel agencé pour osciller par rapport à ladite platine, ledit élément inertiel étant soumis à l'action de moyens de rappel élastique fixés directement ou indirectement à ladite platine, et ledit élément inertiel étant agencé pour coopérer avec un mobile d'échappement que comporte ledit mécanisme d'échappement et qui pivote autour d'un axe principal.The invention relates to a watch movement for a mechanical watch, comprising, arranged on a plate, a resonator mechanism and an exhaust mechanism subjected to the pair of motor means that comprises said movement, said resonator mechanism comprising an inertial element arranged to oscillate with respect to said plate, said inertial element being subjected to the action of elastic return means fixed directly or indirectly to said plate, and said inertial element being arranged to cooperate with an escape wheel that includes said exhaust mechanism and which pivots around a main axis.
L'invention concerne encore une montre mécanique comportant au moins un tel mouvement.The invention also relates to a mechanical watch comprising at least one such movement.
L'invention concerne le domaine des mécanismes résonateurs constituant les bases de temps des montres mécaniques.The invention relates to the field of resonator mechanisms constituting the time bases of mechanical watches.
La plupart des montres mécaniques actuelles comportent un résonateur de type balancier-spiral, qui constitue la base de temps de la montre, et un mécanisme d'échappement, généralement à ancre suisse, lequel remplit deux fonctions principales:
- l'entretien des va-et-vient du résonateur ;
- le comptage de ces va-et-vient.
- maintenance of the comings and goings of the resonator;
- Counting these back and forth.
Le mécanisme d'échappement doit être robuste, résister aux chocs, et être conçu pour éviter de coincer le mouvement (renversement).The exhaust mechanism must be strong, shock-resistant, and designed to avoid pinching the movement (overturning).
Un résonateur mécanique combine au minimum un élément inertiel et un élément de rappel élastique. Dans le balancier-spiral, le spiral joue le rôle d'élément de rappel élastique pour l'élément inertiel que constitue le balancier.A mechanical resonator combines at least one inertial element and an elastic return element. In the spiral balance, the spiral acts as an elastic return element for the inertial element that constitutes the balance.
Le balancier est guidé en rotation par des pivots qui tournent dans des paliers lisses en rubis. Cela donne lieu à des frottements, et donc à des pertes d'énergie et des perturbations de marche, que l'on cherche à supprimer. Les pertes sont caractérisées par le facteur de qualité Q. On cherche à maximiser ce facteur Q.The balance is guided in rotation by pivots which turn in smooth ruby bearings. This gives rise to friction, and therefore to energy losses and disturbances, which we seek to remove. The loss are characterized by quality factor Q. We seek to maximize this Q factor.
L'échappement à ancre suisse a un rendement énergétique faible (environ 30%). Ce faible rendement provient du fait que les mouvements de l'échappement sont saccadés, qu'il y a des « chutes » (chemin perdus pour s'accommoder des erreurs d'usinage) et, aussi, du fait que plusieurs composants se transmettent leur mouvement via des plans inclinés qui frottent les uns par rapport aux autres.The Swiss lever escapement has a low fuel efficiency (about 30%). This low performance comes from the fact that the movements of the exhaust are jerky, that there are "falls" (path lost to accommodate machining errors) and, also, that several components are transmitted their movement via inclined planes that rub against each other.

La demande de brevet
La présente invention se propose de mettre au point un mouvement d'horlogerie combinant un mécanisme résonateur d'horlogerie isochrone particulier, et un mécanisme d'échappement, agencés en relation l'un avec l'autre de façon à améliorer le facteur de qualité du résonateur, notamment en supprimant les frottements associés aux pivots classiques, et à augmenter le rendement d'échappement, en supprimant les saccades usuelles de l'échappement.The present invention proposes to develop a clockwork movement combining a particular isochronous clock resonator mechanism, and an escape mechanism, arranged in relation to one another so as to improve the quality factor of the resonator, in particular by eliminating the friction associated with conventional pivots, and to increase the exhaust efficiency, by eliminating the usual saccades of the exhaust.
Pour atteindre ces objectifs, l'invention propose un résonateur dans lequel l'élément de rappel élastique constitue également le guidage, ainsi que des architectures de mécanismes permettant des interactions continues, sans saccade, entre résonateur et roue d'échappement. On doit, pour ce faire, concéder l'utilisation d'au moins un deuxième degré de liberté du résonateur, le deuxième degré de liberté étant déphasé par rapport au premier. Afin que le résonateur ne soit pas sensible à la gravité, ni aux chocs en translation, on choisit deux degrés de liberté en rotation, dont les axes passent par le centre de masse de l'élément inertiel.To achieve these objectives, the invention proposes a resonator in which the elastic return element also constitutes the guide, as well as mechanisms architectures allowing continuous interactions, without saccade, between resonator and escape wheel. To do this, we must concede the use of at least a second degree of freedom of the resonator, the second degree of freedom being out of phase with the first. So that the resonator is not sensitive to gravity or to shocks in translation, two degrees of freedom in rotation are chosen, the axes of which pass through the center of mass of the inertial element.
Ainsi, l'invention concerne un mouvement d'horlogerie selon la revendication 1.Thus, the invention relates to a watch movement according to

Les axes de rotation des rotations flexibles sont perpendiculaires et passent par le centre de masse G de l'élément inertiel 2 du résonateur 100.The axes of rotation of the flexible rotations are perpendicular and pass through the center of mass G of the
L'invention est ici illustrée, non limitativement, avec un élément inertiel 2 unique.The invention is here illustrated, without limitation, with a single

Selon l'invention, le cardan flexible comporte :
- au moins un premier guidage rotatif flexible, notamment sans pivot, qui définit un axe de rotation D1= e3, encastré à une
platine 1 d'un côté, et lié de l'autre côté à un composant intermédiaire 35 appelé croisillon, - et au moins un deuxième guidage rotatif flexible, notamment sans pivot, définissant un axe de rotation n, dit aussi ligne des noeuds, lié à ce
croisillon 35 d'un côté, et lié à l'élément inertiel 2 durésonateur 100 de l'autre.
- at least one first flexible rotary guide, in particular without a pivot, which defines an axis of rotation D1 = e3, embedded in a
plate 1 on one side, and connected on the other side to anintermediate component 35 called a cross, - and at least one second flexible rotating guide, in particular without a pivot, defining an axis of rotation n, also called line of the nodes, linked to this
crosspiece 35 on one side, and connected to theinertial element 2 of theresonator 100 of the other.

Ces deux dernières caractéristiques permettent d'obtenir l'isochronisme du système, quelle que soit la trajectoire de l'élément inertiel 2.These last two characteristics make it possible to obtain the isochronism of the system, whatever the trajectory of the
En effet, ces caractéristiques simplifient le Lagrangien général, souvent dénommé par un L cursif majuscule, et ici exprimé par l'expression « Lag »,qui est égal à la différence entre l'énergie cinétique Ec = T (totale, qui fait intervenir la vitesse) et l'énergie potentielle Ep = V (totale, qui fait intervenir la position) du système :
L'invention permet donc d'aboutir au meilleur isochronisme possible.The invention therefore makes it possible to achieve the best possible isochronism.
On peut encore, dans un mode particulier, imposer que la fréquence soit identique entre les oscillations d'angles θ et ψ.One can still, in a particular mode, impose that the frequency is identical between oscillations of angles θ and ψ.
De façon particulière, la période d'oscillation selon les deux rotations est sensiblement identique. C'est-à-dire que:
