Description

Domaine technique de l'inventionTechnical field of the invention

L'invention se rapporte à un organe réglant à ressort-spiral muni de moyens de compensation de la température, notamment pour l'horlogerie.The invention relates to a spiral spring regulating member provided with temperature compensation means, particularly for watchmaking.

Arrière-plan technologiqueTechnology background

La plupart des montres mécaniques actuelles sont munies d'un balancier-spiral et d'un mécanisme d'échappement à ancre suisse. Le balancier-spiral constitue la base de temps de la montre. On l'appelle aussi résonateur ou organe réglant.Most current mechanical watches are equipped with a sprung balance and a Swiss anchor escapement mechanism. The sprung balance constitutes the time base of the watch. It is also called a resonator or regulating organ.

L'échappement, quant à lui, remplit deux fonctions principales:

  • entretenir les va-et-vient du résonateur ;
  • compter ces va-et-vient.
The exhaust, on the other hand, performs two main functions:
  • maintain the comings and goings of the resonator;
  • count these comings and goings.

Pour constituer un résonateur mécanique, il faut un élément inertiel, un guidage et un élément de rappel élastique. Traditionnellement, un ressort-spiral joue le rôle d'élément de rappel élastique pour l'élément inertiel que constitue un balancier. Ce balancier est guidé en rotation par des pivots, qui tournent généralement dans des paliers lisses en rubis.To constitute a mechanical resonator, you need an inertial element, guidance and an elastic return element. Traditionally, a spiral spring plays the role of an elastic return element for the inertial element that constitutes a balance wheel. This balance wheel is guided in rotation by pivots, which generally rotate in plain ruby bearings.

On choisit une fréquence pour le résonateur mécanique, qui est déterminée pour obtenir une marche prédéfinie pour le mouvement d'horlogerie.A frequency is chosen for the mechanical resonator, which is determined to obtain a predefined rate for the clock movement.

Cependant, pendant son fonctionnement, un tel résonateur mécanique peut être soumis à des perturbations provoquées par des changements de paramètres extérieurs, qui engendrent des variations de fréquence du résonateur. Ces paramètres sont par exemple la température, la pression, l'humidité, où la gravité. La variation de fréquence du résonateur a pour conséquence une erreur dans la mesure du temps et donc de la marche du mouvement d'horlogerie.However, during its operation, such a mechanical resonator may be subject to disturbances caused by changes in external parameters, which generate variations in frequency of the resonator. These parameters are for example temperature, pressure, humidity, or gravity. The frequency variation of the resonator results in an error in the measurement of time and therefore in the running of the clock movement.

Le document CH 704687 décrit un organe réglant comprenant un ressort-spiral et un organe de correction de la position du piton pour corriger les déformations du ressort-spiral dues à certains paramètres, en particulier la température.The document CH 704687 describes a regulating member comprising a spiral spring and a member for correcting the position of the eyebolt to correct deformations of the spiral spring due to certain parameters, in particular temperature.

Néanmoins, un tel organe de correction n'atteint pas un niveau de précision souhaité.However, such a correction member does not achieve a desired level of precision.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de pallier tout ou partie des inconvénients cités précédemment en proposant un organe réglant d'horlogerie à ressort-spiral muni de moyens de compensation de la température plus précis.The aim of the present invention is to overcome all or part of the drawbacks cited above by proposing a watchmaking regulating organ with a spiral spring provided with more precise temperature compensation means.

A cet effet, l'invention se rapporte à un organe réglant rotatif pour mouvement d'horlogerie comprenant une masse oscillante, par exemple un balancier, un ressort-spiral comprenant un ruban flexible enroulé sur lui-même selon plusieurs spires, le ruban ayant une rigidité prédéfinie pour permettre à la masse oscillante d'effectuer un mouvement oscillatoire rotatif, le ruban comprenant une extrémité externe.For this purpose, the invention relates to a rotary regulating member for a timepiece movement comprising an oscillating mass, for example a balance wheel, a spiral spring comprising a flexible ribbon wound on itself in several turns, the ribbon having a predefined rigidity to allow the oscillating mass to perform a rotary oscillatory movement, the ribbon comprising an external end.

L'invention est remarquable en ce que l'organe réglant comprend un dispositif élastique de compensation de la température configuré pour adapter sa raideur en fonction de la température afin de compenser l'effet de la température sur l'organe réglant, le dispositif élastique comprenant un élément élastique reliant l'extrémité externe à un premier support immobile par rapport au mouvement d'horlogerie, ainsi que des moyens de précontrainte pour appliquer une force ou un couple variable sur l'élément élastique en fonction de la température.The invention is remarkable in that the regulating member comprises an elastic temperature compensation device configured to adapt its stiffness as a function of the temperature in order to compensate for the effect of the temperature on the regulating member, the elastic device comprising an elastic element connecting the external end to a first support stationary with respect to the clockwork movement, as well as prestressing means for applying a variable force or torque on the elastic element as a function of the temperature.

Grâce à l'invention, les moyens de précontrainte exercent une force ou un couple variable sur l'élément élastique en fonction de la température, de sorte que l'organe réglant conserve sensiblement une marche précise malgré des modifications importantes de la température. En effet, lorsque la température change, les moyens de précontrainte modifient la force ou le couple exercé sur l'élément élastique, de sorte qu'on modifie la raideur de l'ensemble comprenant l'élément élastique et le ressort-spiral. En modifiant la raideur de cet ensemble, on ajuste la marche de l'organe réglant. Par conséquent, lorsque la température change, le dispositif élastique est mécaniquement impacté pour ajuster la marche du ressort-spiral à ce changement.Thanks to the invention, the prestressing means exert a variable force or torque on the elastic element as a function of the temperature, so that the regulating member substantially maintains a precise course despite significant changes in the temperature. Indeed, when the temperature changes, the prestressing means modify the force or the torque exerted on the elastic element, so that the stiffness of the assembly comprising the elastic element and the spiral spring is modified. By modifying the stiffness of this assembly, we adjust the operation of the regulating organ. Consequently, when the temperature changes, the elastic device is mechanically impacted to adjust the action of the spiral spring to this change.

Cet élément élastique modifie la rigidité du point d'attache et apporte une flexibilité supplémentaire au résonateur. Ainsi, la rigidité effective du résonateur comprend la rigidité du ruban et la rigidité de l'élément élastique. La force ou le couple variable permet de pré-contraindre l'élément élastique, de préférence sans pré-contraindre le ruban et sans déplacer l'extrémité du ruban. En pré-contraignant l'élément élastique, sa rigidité change, tandis que la rigidité du ruban reste inchangée, puisqu'il n'est pas précontraint et que son extrémité ne se déplace pas.This elastic element modifies the rigidity of the attachment point and provides additional flexibility to the resonator. Thus, the effective stiffness of the resonator includes the stiffness of the ribbon and the stiffness of the elastic element. The variable force or torque allows the elastic element to be pre-stressed, preferably without pre-stressing the tape and without moving the end of the tape. By pre-stressing the elastic element, its rigidity changes, while the rigidity of the ribbon remains unchanged, since it is not pre-stressed and its end does not move.

En changeant la flexibilité de l'élément élastique, la rigidité du résonateur (rigidité du ruban et rigidité de l'élément élastique) change, ce qui modifie par conséquent la marche du résonateur. L'élément élastique étant, de préférence, plus rigide que le ruban, la part de la rigidité de l'élément élastique dans la rigidité d'ensemble est inférieure à celle du ruban. Par conséquent, une modification de la rigidité de l'élément élastique modifie la rigidité de l'ensemble du résonateur, et par conséquent règle sa marche de manière fine, ce qui permet d'ajuster précisément la fréquence de notre base de temps. On obtient ainsi une grande précision dans le maintien de la marche en fonction de la température.By changing the flexibility of the elastic element, the stiffness of the resonator (ribbon stiffness and stiffness of the elastic element) changes, which consequently changes the action of the resonator. The elastic element being preferably more rigid than the ribbon, the share of the rigidity of the elastic element in the overall rigidity is less than that of the ribbon. Consequently, a modification of the rigidity of the elastic element modifies the rigidity of the entire resonator, and consequently fine-tunes its operation, which makes it possible to precisely adjust the frequency of our time base. We thus obtain great precision in maintaining operation as a function of temperature.

Dans les deux modes de réalisation, l'organe réglant 1, 10 comprend un ressort-spiral muni d'un ruban flexible 2 enroulé sur lui-même selon plusieurs spires. Le ruban flexible 2 comprend une extrémité externe 9 et une extrémité interne 8.In both embodiments, the regulating member 1, 10 comprises a spiral spring provided with a flexible ribbon 2 wound on itself in several turns. The flexible ribbon 2 comprises an external end 9 and an internal end 8.

L'organe réglant 1, 10 comprend une masse oscillante, par exemple un balancier annulaire, non représenté sur les figures, qui est relié à l'extrémité interne 8 du ruban 2, le ruban 2 ayant une rigidité prédéfinie pour permettre à la masse oscillante d'effectuer un mouvement oscillatoire rotatif. Par exemple, la masse oscillante comprend un arbre de rotation axial, l'extrémité interne 8 du ruban 2 étant reliée audit arbre.The regulating member 1, 10 comprises an oscillating mass, for example an annular balance, not shown in the figures, which is connected to the internal end 8 of the ribbon 2, the ribbon 2 having a predefined rigidity to allow the oscillating mass to perform a rotary oscillatory movement. For example, the oscillating mass comprises an axial rotation shaft, the internal end 8 of the ribbon 2 being connected to said shaft.

De préférence, l'organe réglant 1, 10 s'étend sensiblement dans un même plan, excepté la masse oscillante, qui oscille dans un plan parallèle, au-dessus du ressort-spiral.Preferably, the regulating member 1, 10 extends substantially in the same plane, except for the oscillating mass, which oscillates in a parallel plane, above the spiral spring.

Selon l'invention, l'organe réglant 1, 10 comprend un dispositif élastique 50 de compensation d'un paramètre extérieur configuré pour adapter la raideur de l'élément élastique 5 en fonction de la température afin de compenser l'effet de la température sur l'organe réglant 1, 10.According to the invention, the regulating member 1, 10 comprises an elastic device 50 for compensating an external parameter configured to adapt the stiffness of the elastic element 5 as a function of the temperature in order to compensate for the effect of the temperature on the regulating organ 1, 10.

Le dispositif élastique 50 comprend un élément élastique 5 reliant l'extrémité externe 9 à un support immobile 7 par rapport au mouvement d'horlogerie, par exemple à une platine. Le dispositif élastique 50 comprend en outre des moyens de précontrainte 6 pour appliquer une force ou un couple variable sur l'élément élastique 5 en fonction du paramètre extérieur.The elastic device 50 comprises an elastic element 5 connecting the external end 9 to a stationary support 7 relative to the watch movement, for example to a plate. The elastic device 50 further comprises prestressing means 6 for applying a variable force or torque to the elastic element 5 as a function of the external parameter.

L'élément élastique 5 comprend ici un corps ponctuel suspendu 3 et une paire de lames décroisées 4 reliant le corps ponctuel suspendu 3 au support immobile 7. Le corps ponctuel suspendu 3 est par exemple un corps cylindrique de hauteur sensiblement égale au diamètre, les lames décroisées 4 s'écartant depuis le corps ponctuel suspendu 3 jusqu'au support immobile 7.The elastic element 5 here comprises a suspended point body 3 and a pair of uncrossed blades 4 connecting the suspended point body 3 to the immobile support 7. The suspended point body 3 is for example a cylindrical body of height substantially equal to the diameter, the blades uncrossed 4 moving away from the suspended point body 3 to the immobile support 7.

L'élément élastique 5 est agencé dans le prolongement du ruban flexible 2, le ressort spiral et l'élément élastique 5 étant adjacents, mais en évitant les contacts pendant l'oscillation de la masse oscillante.The elastic element 5 is arranged in the extension of the flexible ribbon 2, the spiral spring and the elastic element 5 being adjacent, but avoiding contact during the oscillation of the oscillating mass.

Les moyens de précontrainte 6 sont configurés pour exercer la force ou le couple sur le corps ponctuel suspendu 3. Les moyens de précontrainte 6 comprennent une partie ressort munie d'une lame flexible 11 reliée au corps ponctuel suspendu 3. La première lame flexible 11 s'étend dans l'axe de l'élément élastique, tangentiellement au ressort spiral, et est légèrement décalé par rapport à l'extrémité externe 9.The prestressing means 6 are configured to exert the force or torque on the suspended point body 3. The prestressing means 6 comprise a spring part provided with a flexible blade 11 connected to the suspended point body 3. The first flexible blade 11 s 'extends in the axis of the elastic element, tangentially to the spiral spring, and is slightly offset relative to the external end 9.

Dans le premier mode de réalisation de la figure 1, la partie ressort des moyens de précontrainte 6 comprend une table de translation munie d'un premier élément mobile 12 en forme de L et d'un second support immobile 13 par rapport au mouvement. Le premier élément mobile 12 est relié à la lame flexible 11 par une extrémité d'un premier bras du L. Le second bras du L comporte une excroissance 53 arrondie du côté externe. La table de translation comprend deux lames flexibles 14 sensiblement parallèles reliant le premier élément mobile 12 au second support immobile 13.In the first embodiment of the figure 1 , the spring part of the prestressing means 6 comprises a translation table provided with a first movable element 12 in the shape of an L and a second immobile support 13 relative to the movement. The first movable element 12 is connected to the flexible blade 11 by one end of a first arm of the L. The second arm of the L includes a rounded projection 53 on the external side. The translation table comprises two substantially parallel flexible blades 14 connecting the first movable element 12 to the second stationary support 13.

Les moyens de de précontrainte 6 comportent en outre un corps déformable 15 thermiquement en fonction de la température, le corps déformable 15 exerçant la force ou le couple variable sur l'élément mobile 12.The prestressing means 6 further comprise a thermally deformable body 15 as a function of the temperature, the deformable body 15 exerting the variable force or torque on the movable element 12.

Dans cet exemple, le corps déformable thermiquement 15 est un bilame dont la déformation est provoquée par la température. Le bilame présente un corps s'étendant longitudinalement, et comprend deux parties allongées 51, 52 associées longitudinalement. Les deux parties allongées 51, 52 sont formées chacune d'un matériau différent, avec des propriétés de déformation thermique différentes l'une de l'autre. Ainsi, sous l'effet de la chaleur, le bilame se déforme latéralement, une extrémité 55 du bilame étant retenue, l'autre extrémité pouvant se déplacer et déformer le bilame pour le courber d'un côté.In this example, the thermally deformable body 15 is a bimetal whose deformation is caused by the temperature. The bimetallic strip has a body extending longitudinally, and comprises two elongated parts 51, 52 associated longitudinally. The two elongated parts 51, 52 are each formed of a different material, with thermal deformation properties different from each other. Thus, under the effect of heat, the bimetallic strip deforms laterally, one end 55 of the bimetallic strip being retained, the other end being able to move and deform the bimetallic strip to bend it to one side.

Le bilame est disposé perpendiculairement à l'élément mobile 12, de sorte qu'une première partie libre 54 soit en contact avec l'excroissance 53 du deuxième bras du L. L'extrémité retenue 55 est maintenue par une seconde table de translation comprenant un deuxième élément mobile 18 et une deuxième paire 17 de lames flexibles parallèles reliant le deuxième élément mobile 18 à un troisième support immobile 19 par rapport à la platine du mouvement. Le deuxième élément mobile 18 a une forme de L, un bras du L supportant l'extrémité retenue 55 du bilame, tandis que les lames de la deuxième paire 17 de lames, relient la face interne 56 du second bras au troisième support immobile 19. Les lames de la deuxième paire 17 de lames sont agencées perpendiculairement au bilame en position de repos des moyens de précontrainte 6.The bimetallic strip is arranged perpendicular to the movable element 12, so that a first free part 54 is in contact with the protrusion 53 of the second arm of the L. The retained end 55 is held by a second translation table comprising a second movable element 18 and a second pair 17 of parallel flexible blades connecting the second movable element 18 to a third immobile support 19 relative to the movement plate. The second movable element 18 has an L shape, one arm of the L supporting the retained end 55 of the bimetallic strip, while the blades of the second pair 17 of blades connect the internal face 56 of the second arm to the third immobile support 19. The blades of the second pair 17 of blades are arranged perpendicular to the bimetallic strip in the rest position of the prestressing means 6.

En cas de modification de la température, le corps déformable 15, ici le bilame, se courbe ou se redresse, de sorte que la première partie libre 54 exerce une force plus ou moins importante sur l'excroissance, et donc sur le premier élément mobile 12, qui se déplace en étant guidé par la première table de translation. Ainsi, par l'intermédiaire de la première lame flexible 11, l'élément élastique 5 reçoit une force ou un couple modifiant sa raideur et donc la marche de de l'organe réglant 1.In the event of a change in temperature, the deformable body 15, here the bimetallic strip, bends or straightens, so that the first free part 54 exerts a more or less significant force on the protrusion, and therefore on the first movable element. 12, which moves while being guided by the first translation table. Thus, via the first flexible blade 11, the elastic element 5 receives a force or a torque modifying its stiffness and therefore the operation of the regulating member 1.

Des moyens de réglage, telle une vis, peuvent être ajoutés pour exercer une force 57 sur le deuxième élément mobile 18, en particulier à l'extrémité du deuxième bras 58, parallèlement à l'axe longitudinal du bilame. Ainsi, on peut régler la longueur effective d du bilame, pour régler l'effet des moyens de précontrainte 6 sur l'élément élastique 5, en particulier en fonction de la température. En déplaçant le deuxième élément mobile 18, guidé par la deuxième table de translation, on modifie le contact entre la partie libre 54 et l'excroissance 53, et ainsi on augmente ou on diminue la longueur effective d du bilame. Ainsi, plus la longueur effective est importante, plus la force exercée sur le premier élément mobile 12 varie en fonction de la température.Adjustment means, such as a screw, can be added to exert a force 57 on the second movable element 18, in particular at the end of the second arm 58, parallel to the longitudinal axis of the bimetallic strip. Thus, we can adjust the effective length d of the bimetallic strip, to adjust the effect of the prestressing means 6 on the elastic element 5, in particular as a function of the temperature. By moving the second movable element 18, guided by the second translation table, the contact between the free part 54 and the projection 53 is modified, and thus the effective length d of the bimetallic strip is increased or reduced. Thus, the greater the effective length, the more the force exerted on the first movable element 12 varies as a function of the temperature.

En cas de déformation courbe du corps déformable 15, la partie libre 54 pousse le premier élément mobile 12, de sorte que la première lame flexible 11 transmette une force ou un couple sur le corps ponctuel suspendu 3. Ainsi, la raideur de la paire de lames décroisées 4 diminue. Inversement, si le corps déformable 15 se redresse, la force ou un couple sur le corps ponctuel suspendu 3 diminue, de sorte que la raideur de la paire de lames décroisées 4 augmente.In the event of curved deformation of the deformable body 15, the free part 54 pushes the first movable element 12, so that the first flexible blade 11 transmits a force or a torque on the suspended point body 3. Thus, the stiffness of the pair of uncrossed blades 4 decreases. Conversely, if the deformable body 15 straightens, the force or torque on the suspended point body 3 decreases, so that the stiffness of the pair of uncrossed blades 4 increases.

Dans le deuxième mode de réalisation, l'organe réglant 10 comprend un ressort spiral, une masse oscillante (non représentée sur la figure), un élément élastique 5, et une première lame flexible 11 identique au premier mode de réalisation.In the second embodiment, the regulating member 10 comprises a spiral spring, an oscillating mass (not shown in the figure), an elastic element 5, and a first flexible blade 11 identical to the first embodiment.

Pour exercer la force ou le couple sur l'élément élastique 5, la partie ressort des moyens de précontrainte 6 comprend un premier élément mobile 22 allongé, relié à la lame flexible 11 et disposé dans son prolongement. Une première paire de lames flexibles parallèles 24 relie le premier élément mobile 22 à un deuxième support immobile 23 pour former une table de translation et guider le déplacement du premier élément mobile 22.To exert the force or torque on the elastic element 5, the spring part of the prestressing means 6 comprises a first elongated movable element 22, connected to the flexible blade 11 and arranged in its extension. A first pair of parallel flexible blades 24 connects the first movable element 22 to a second immobile support 23 to form a translation table and guide the movement of the first movable element 22.

La partie ressort comprend une deuxième paire de lames flexibles parallèles 25 agencée du même côté que la première paire de lames flexibles parallèles 24, et relie le premier élément mobile 22 à un deuxième élément mobile 28.The spring part comprises a second pair of parallel flexible blades 25 arranged on the same side as the first pair of parallel flexible blades 24, and connects the first movable element 22 to a second movable element 28.

Le deuxième élément mobile 28 est relié latéralement au corps déformable 15 thermiquement par une deuxième lame flexible 21 sensiblement parallèle au premier élément mobile 22 en position de repos de l'organe réglant 10.The second movable element 28 is connected laterally to the thermally deformable body 15 by a second flexible blade 21 substantially parallel to the first movable element 22 in the rest position of the regulating member 10.

Dans ce mode réalisation, le corps déformable est de préférence également un bilame agencé perpendiculairement à la deuxième lame flexible 21 et au premier élément mobile 22. La deuxième lame flexible 21 est relie au sommet de la partie libre du bilame, ce dernier étant maintenu par un support fixe à sa base.In this embodiment, the deformable body is preferably also a bimetallic strip arranged perpendicularly to the second flexible blade 21 and to the first movable element 22. The second flexible blade 21 is connected to the top of the free part of the bimetallic strip, the latter being held by a fixed support at its base.

Ainsi, lorsque le bilame se courbe ou se redresse, la deuxième lame flexible 21 transmet un déplacement au deuxième élément mobile 28, qui le transmet au premier élément mobile 22 par la deuxième paire de lames flexibles parallèles 25. Le premier élément mobile 22 est guidé par la première table de translation pour transmettre la force ou le couple à l'élément élastique 5 à travers la première lame flexible 11.Thus, when the bimetallic strip curves or straightens, the second flexible blade 21 transmits a movement to the second movable element 28, which transmits it to the first movable element 22 by the second pair of parallel flexible blades 25. The first movable element 22 is guided by the first translation table to transmit the force or torque to the elastic element 5 through the first flexible blade 11.

De manière semblable au premier mode de réalisation, la variation de température va engendrer une déformation du corps déformable thermiquement 15, et une modification de la raideur de l'élément élastique 5, et donc de la marche de l'organe réglant 10.Similar to the first embodiment, the temperature variation will cause a deformation of the thermally deformable body 15, and a modification of the stiffness of the elastic element 5, and therefore of the operation of the regulating member 10.

Une troisième paire de lames flexibles parallèles 26, relie le deuxième élément mobile 28 à un troisième élément mobile 27. La troisième paire de lames flexibles parallèles 26 et le troisième élément mobile 27 étant agencés en série de la deuxième paire de lames flexibles parallèles 25 et du deuxième élément mobile 28.A third pair of parallel flexible blades 26 connects the second movable element 28 to a third movable element 27. The third pair of parallel flexible blades 26 and the third movable element 27 being arranged in series with the second pair of parallel flexible blades 25 and of the second mobile element 28.

Des moyens de réglage, telle une vis, peuvent être ajoutés pour exercer une force 59 sur le troisième élément mobile 27. En augmentant la force 59, le déplacement du bilame est transmis plus faiblement au premier élément mobile 22, tandis qu'en diminuant la force, le déplacement du bilame est transmis plus fortement au premier élément mobile 22. Les moyens de réglage permettent de régler la sensibilité des moyens de précontrainte 6 en fonction de la température.Adjustment means, such as a screw, can be added to exert a force 59 on the third movable element 27. By increasing the force 59, the movement of the bimetallic strip is transmitted more weakly to the first movable element 22, while by reducing the force, the movement of the bimetallic strip is transmitted more strongly to the first movable element 22. The adjustment means make it possible to adjust the sensitivity of the prestressing means 6 as a function of the temperature.

L'invention se rapporte également à un mouvement d'horlogerie, non représenté sur les figures, le mouvement comprenant un organe réglant rotatif 1, 10 tel que décrit précédemment.The invention also relates to a clock movement, not shown in the figures, the movement comprising a rotary regulating member 1, 10 as described above.

Naturellement, l'invention n'est pas limitée aux modes de réalisation décrits en référence aux figures et des variantes pourraient être envisagées sans sortir du cadre de l'invention.Naturally, the invention is not limited to the embodiments described with reference to the figures and variants could be considered without departing from the scope of the invention.
