Description

Domaine technique de l'inventionTechnical field of the invention

L'invention se rapporte à un organe réglant d'horlogerie à guidage flexible muni de moyens de compensation de la pression.The invention relates to a watchmaking regulating member with flexible guidance provided with pressure compensation means.

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 organe réglant, 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 regulating organ, 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 utilise aujourd'hui des guidages flexibles comme partie ressort pour former un pivot virtuel. Les guidages flexibles à pivot virtuel permettent d'améliorer sensiblement les résonateurs horlogers. Les plus simples sont des pivots à lames croisées, composés de deux dispositifs de guidage à lames droites qui se croisent, en général perpendiculairement. Ces deux lames peuvent être, soit tridimensionnelles dans deux plans différents, soit bidimensionnelles dans un même plan et sont alors comme soudées à leur point de croisement. Mais il existe aussi des guidages à lames décroisées de type RCC (pour « Remote Center Compliance » en anglais), qui ont des lames droites ne se croisant pas. Un tel résonateur est décrit dans le document EP 2911912 , ou dans les documents EP14199039 , et EP16155039 .Today, flexible guides are used as spring parts to form a virtual pivot. Flexible virtual pivot guides make it possible to significantly improve watch resonators. The simplest are cross-blade pivots, consisting of two straight-blade guide devices that cross each other, usually perpendicularly. These two blades can be either three-dimensional in two different planes, or two-dimensional in the same plane and are then welded at their crossing point. But there are also guides with uncrossed blades of the RCC type (for “Remote Center Compliance” in English), which have straight blades not crossing. Such a resonator is described in the document EP 2911912 , or in the documents EP14199039 , And EP16155039 .

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 direction de la gravité. La variation de fréquence du résonateur a pour conséquence une erreur dans la mesure du temps.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 the direction of gravity. The variation in frequency of the resonator results in an error in the measurement of time.

Par exemple, 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 la température.For example, 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 temperature.

Aujourd'hui, il n'existe pas d'organe réglant muni de moyens de compensation configurés pour compenser les variations de pression ambiante. Ainsi, lorsque la pression change, par exemple à cause de l'altitude, l'organe réglant perd en précision, car la différence de pression modifie les frottements aérodynamiques de l'organe réglant. Par exemple, une augmentation de la pression engendre une diminution de la fréquence d'oscillation de l'organe réglant.Today, there is no regulating organ equipped with compensation means configured to compensate for variations in ambient pressure. Thus, when the pressure changes, for example because of altitude, the regulating member loses precision, because the pressure difference modifies the aerodynamic friction of the regulating member. For example, an increase in pressure causes a reduction in the oscillation frequency of the regulating organ.

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 guidage flexible muni de moyens de compensation de la pression, qui soient précis et adaptables aux guidages flexibles.The aim of the present invention is to overcome all or part of the drawbacks cited above by proposing a watchmaking regulating member with flexible guidance provided with pressure compensation means, which are precise and adaptable to flexible guides.

A cet effet, l'invention se rapporte à un organe réglant pour mouvement d'horlogerie, l'organe réglant comprenant une masse oscillante, par exemple un balancier, un guidage flexible comprenant au moins deux lames flexibles reliant un support rigide à la masse oscillante pour permettre à la masse oscillante d'effectuer un mouvement rotatif autour d'un pivot virtuel.For this purpose, the invention relates to a regulating member for a clock movement, the regulating member comprising an oscillating mass, for example a balance wheel, a flexible guide comprising at least two flexible blades connecting a rigid support to the oscillating mass to allow the oscillating mass to perform a rotary movement around a virtual pivot.

L'invention est remarquable en ce que l'organe réglant comprend un dispositif élastique de compensation de la pression extérieure, le dispositif élastique de compensation étant agencé en série du support rigide, de manière à relier le support rigide à des moyens de fixation de l'organe réglant sur le mouvement d'horlogerie, le dispositif élastique de compensation étant configuré pour adapter sa raideur en fonction de la pression extérieure afin de compenser l'effet de la pression extérieure sur l'organe réglant.The invention is remarkable in that the regulating member comprises an elastic device for compensating for the external pressure, the elastic compensation device being arranged in series with the rigid support, so as to connect the rigid support to means for fixing the the regulating member on the clockwork movement, the elastic compensation device being configured to adapt its stiffness as a function of the external pressure in order to compensate for the effect of the external pressure on the regulating member.

Grâce à l'invention, les moyens de précontrainte exercent une force ou un couple variable sur l'élément élastique du dispositif élastique de compensation en fonction de la pression, de sorte que l'organe réglant conserve sensiblement une marche précise malgré des modifications importantes de la pression. En effet, lorsque la pression change, les moyens de précontrainte modifient la force ou le couple exercé sur l'élément élastique, de sorte qu'on modifie la raideur du guidage flexible. En modifiant la raideur du guidage flexible, on ajuste la marche de l'organe réglant. Par conséquent, lorsque la pression change, le dispositif élastique est mécaniquement impacté pour ajuster la marche du guidage flexible à ce changement.Thanks to the invention, the prestressing means exert a variable force or torque on the elastic element of the elastic compensation device as a function of the pressure, so that the regulating member substantially maintains a precise course despite significant modifications of pressure. Indeed, when the pressure changes, the prestressing means modify the force or the torque exerted on the elastic element, so that the stiffness of the flexible guide is modified. By modifying the stiffness of the flexible guide, the action of the regulating member is adjusted. Consequently, when the pressure changes, the elastic device is mechanically impacted to adjust the course of the flexible guide 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 guidage flexible 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 guidage flexible et sans déplacer l'extrémité du guidage flexible. En pré-contraignant l'élément élastique, sa rigidité change, tandis que la rigidité du guidage flexible 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 rigidity of the resonator includes the rigidity of the flexible guide and the rigidity of the elastic element. The variable force or torque makes it possible to pre-stress the elastic element, preferably without pre-stressing the flexible guide and without moving the end of the flexible guide. By pre-stressing the elastic element, its rigidity changes, while the rigidity of the flexible guide remains unchanged, since it is not pre-stressed and its end does not move.

En modifiant la rigidité de l'élément élastique, la rigidité du résonateur (rigidité du guidage flexible 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 guidage flexible, la part de la rigidité de l'élément élastique dans la rigidité d'ensemble est inférieure à celle du guidage flexible. 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 pression.By changing the rigidity of the elastic element, the rigidity of the resonator (rigidity of the flexible guide and rigidity of the elastic element) changes, which consequently modifies the operation of the resonator. The elastic element being preferably more rigid than the flexible guide, the share of the rigidity of the elastic element in the overall rigidity is less than that of the flexible guide. 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 walking depending on the pressure.

Description détaillée de l'inventionDetailed description of the invention

Les figures 1 et 2, représentent un mode de réalisation d'un organe réglant 1 selon l'invention, l'organe réglant 1, comprenant un dispositif élastique 50 configuré pour compenser une variation de pression exercée sur l'organe réglant 1. De tels organes réglants 1 sont destinés à être agencés dans un mouvement d'horlogerie pour le réguler.THE figures 1 and 2 , represent an embodiment of a regulating member 1 according to the invention, the regulating member 1, comprising an elastic device 50 configured to compensate for a variation in pressure exerted on the regulating member 1. Such regulating members 1 are intended to be arranged in a clockwork movement to regulate it.

Dans ce mode de réalisation, l'organe réglant 1 comprend un guidage flexible 2 et une masse oscillante 19. Une masse oscillante peut par exemple être de forme annulaire ou un bras en forme d'os.In this embodiment, the regulating member 1 comprises a flexible guide 2 and an oscillating mass 19. An oscillating mass can for example be annular in shape or a bone-shaped arm.

La masse oscillante 19 est ici de forme annulaire, et comprend une branche 8 traversant l'anneau, la branche 8 étant agencée pour diviser l'anneau en deux parties, une première partie comprenant un tiers de l'anneau, et une deuxième partie comprenant deux tiers de l'anneau. En outre, la masse oscillante 19 comprend des vis de réglage 20 du balourd, ici trois vis. Les vis de réglage 20 sont réparties angulairement autour de l'anneau, et elles traversent l'anneau en direction du centre de l'anneau.The oscillating mass 19 is here of annular shape, and comprises a branch 8 passing through the ring, the branch 8 being arranged to divide the ring into two parts, a first part comprising a third of the ring, and a second part comprising two thirds of the ring. In addition, the oscillating mass 19 includes unbalance adjustment screws 20, here three screws. The adjustment screws 20 are distributed angularly around the ring, and they pass through the ring towards the center of the ring.

De préférence, l'organe réglant 1 s'étend sensiblement dans un même plan, excepté la masse oscillante 19, qui oscille dans un plan parallèle, dans un mouvement rotatif autour d'un pivot virtuel, par exemple au-dessus du guidage flexible 2.Preferably, the regulating member 1 extends substantially in the same plane, except the oscillating mass 19, which oscillates in a parallel plane, in a rotary movement around a virtual pivot, for example above the flexible guide 2 .

Le guidage flexible 2 comprend deux lames flexibles principales 9, et un support rigide 3. Le guidage flexible 2 s'étend selon un axe de symétrie principal. Les lames flexibles principales 9 sont jointes d'une part au support rigide 3 du guidage flexible 2, et d'autre part à la branche 8 de la masse oscillante 19.The flexible guide 2 comprises two main flexible blades 9, and a rigid support 3. The flexible guide 2 extends along a main axis of symmetry. The main flexible blades 9 are joined on the one hand to the rigid support 3 of the flexible guide 2, and on the other hand to the branch 8 of the oscillating mass 19.

Les deux lames principales 9 du guidage flexible 2 sont croisées, de préférence droites et de même longueur. Le point de croisement des lames flexibles principales 9 est plus proche du support rigide 3 que de la branche 8. Les lames flexibles principales 9 sont centrées, de sorte que l'axe de symétrie principal passent par une droite divisant l'anneau en deux.The two main blades 9 of the flexible guide 2 are crossed, preferably straight and of the same length. The crossing point of the main flexible blades 9 is closer to the rigid support 3 than to the branch 8. The main flexible blades 9 are centered, so that the main axis of symmetry passes through a straight line dividing the ring in two.

Le guidage flexible 2 est disposé à l'intérieur de l'anneau dans la deuxième partie plus grande.The flexible guide 2 is arranged inside the ring in the second larger part.

Le support rigide 3 présente un corps allongé sensiblement parallélépipédique.The rigid support 3 has an elongated, substantially parallelepiped body.

Selon l'invention, l'organe réglant 1 comprend un dispositif élastique de compensation 50 de la pression, le dispositif élastique étant agencé en série du support rigide 3 de manière à relier le support rigide 3 à des moyens de fixation 7 de l'organe réglant 1 sur le mouvement d'horlogerie.According to the invention, the regulating member 1 comprises an elastic pressure compensation device 50, the elastic device being arranged in series with the rigid support 3 so as to connect the rigid support 3 to fixing means 7 of the member setting 1 on the clockwork.

Le dispositif élastique de compensation 50 est configuré pour adapter sa raideur en fonction des variations de la pression environnante afin de compenser l'effet de ces variations sur l'organe réglant 1. Le dispositif élastique de compensation 50 a de préférence une raideur supérieure à la paire de lames flexibles principales 9.The elastic compensation device 50 is configured to adapt its stiffness as a function of variations in the surrounding pressure in order to compensate for the effect of these variations on the regulating member 1. The elastic compensation device 50 preferably has a stiffness greater than the pair of main flexible blades 9.

Le dispositif élastique de compensation 50 comprend un élément élastique 5 agencé entre le support rigide 3 et les moyens de fixation 7, ainsi que des moyens de précontrainte 6 pour appliquer une force ou un couple variable sur l'élément élastique 5 et le support rigide 3 en fonction de la pression.The elastic compensation device 50 comprises an elastic element 5 arranged between the rigid support 3 and the fixing means 7, as well as prestressing means 6 for applying a variable force or torque on the elastic element 5 and the rigid support 3 depending on the pressure.

Sur la figure 2, l'élément élastique 5 comprend une paire de lames décroisées 4 reliant le support rigide 3 aux moyens de fixation 7. Les lames décroisées 4 s'étendent du support rigide 3, du côté opposé au côté des lames flexibles principales 9 aux moyens de fixation 7 en s'écartant l'une de l'autre.On the figure 2 , the elastic element 5 comprises a pair of uncrossed blades 4 connecting the rigid support 3 to the fixing means 7. The uncrossed blades 4 extend from the rigid support 3, on the side opposite to the side of the main flexible blades 9 to the fixing means 7 moving away from each other.

Les moyens de précontrainte 6 sont disposés entre les lames flexibles de la paire de lames décroisées 4.The prestressing means 6 are arranged between the flexible blades of the pair of uncrossed blades 4.

Les moyens de précontrainte 6 comprennent une partie ressort exerçant la force ou le couple variable sur le support rigide 3. Ainsi, la raideur du dispositif élastique est modifiée, car les moyens de précontrainte 6 modifient la raideur des lames décroisées 4. La partie ressort est en outre configurée pour subir une force ou un couple variable, qui est transmis à l'élément élastique 5.The prestressing means 6 comprise a spring part exerting the variable force or torque on the rigid support 3. Thus, the stiffness of the elastic device is modified, because the prestressing means 6 modify the stiffness of the uncrossed blades 4. The spring part is further configured to experience a variable force or torque, which is transmitted to the elastic element 5.

Pour transmettre une force ou un couple variable en fonction de la pression extérieure à la partie ressort, les moyens de précontrainte 6 comprennent une capsule anéroïde 10.To transmit a variable force or torque as a function of the external pressure to the spring part, the prestressing means 6 comprise an aneroid capsule 10.

Une telle capsule est généralement utilisée pour mesurer la pression atmosphérique. A cette fin, la capsule comprend un espace au moins en partie vide d'air, et comprend un élément de rappel élastique de type ressort dans l'espace pour retenir une paroi mobile de la capsule. Ainsi, lorsque la pression extérieure augmente, la capsule est comprimée, et lorsque la pression extérieure diminue, la capsule s'élargit.Such a capsule is generally used to measure atmospheric pressure. To this end, the capsule comprises a space at least partly empty of air, and comprises a spring-type elastic return element in the space to retain a movable wall of the capsule. Thus, when the external pressure increases, the capsule is compressed, and when the external pressure decreases, the capsule expands.

Sur la figure 2, la capsule anéroïde 10 comprend un volume variable en fonction de la pression extérieure.On the figure 2 , the aneroid capsule 10 comprises a variable volume depending on the external pressure.

Pour cela, la capsule anéroïde 10 comprend une paroi mobile 13 et une paroi immobile 15 reliées par au moins un ressort 16. Une enceinte étanche, non représentée sur les figures, permet d'instaurer au moins en partie le vide à l'intérieur des parois mobile 13 et immobile 15.For this, the aneroid capsule 10 comprises a movable wall 13 and a stationary wall 15 connected by at least one spring 16. A sealed enclosure, not shown in the figures, makes it possible to establish at least part of the vacuum inside the movable walls 13 and immobile 15.

La paroi immobile 15 est reliée solidairement aux moyens de fixation 7. La paroi immobile 15 a une forme en L, dont le grand segment 21 est sensiblement parallèle aux moyens de fixation 7 et au support, et le petit segment 22 est relié aux moyens de fixation 7 perpendiculairement au grand segment 21.The immobile wall 15 is integrally connected to the fixing means 7. The immobile wall 15 has an L shape, the large segment 21 of which is substantially parallel to the fixing means 7 and to the support, and the small segment 22 is connected to the means of fixing 7 perpendicular to the large segment 21.

La paroi mobile 13 a une forme de L, la paroi mobile 13 étant agencée tête-bêche par rapport à la paroi immobile 15, de sorte que les grands segments 17, 21 des L soient sensiblement en face l'un de l'autre, et que les petits segments 18, 22 des L soient sensiblement en face l'un de l'autre.The movable wall 13 has an L shape, the movable wall 13 being arranged head to tail relative to the stationary wall 15, so that the large segments 17, 21 of the L are substantially opposite each other, and that the small segments 18, 22 of the L are substantially opposite each other.

Les moyens de précontrainte 6 comprennent en outre au moins un ressort, ici deux ressorts 16 reliant les grands segments 17, 21 du côté intérieur, qui forment l'élément de rappel élastique de la capsule anéroïde. En fonction de la pression exercée sur la paroi mobile 13, les ressorts 16 s'étendent, notamment lorsque la pression baisse, ou se contractent, notamment lorsque la pression augmente. Ainsi, ils rapprochent ou éloignent la paroi mobile 13 de la paroi immobile 15.The prestressing means 6 further comprise at least one spring, here two springs 16 connecting the large segments 17, 21 on the interior side, which form the elastic return element of the aneroid capsule. Depending on the pressure exerted on the movable wall 13, the springs 16 extend, particularly when the pressure drops, or contract, particularly when the pressure increases. Thus, they bring the movable wall 13 closer to or further away from the immobile wall 15.

La partie ressort des moyens de précontrainte 6 est reliée au support mobile 3 et à la capsule anéroïde 10, la partie ressort transmettant la force ou le couple de la capsule anéroïde 10 à l'élément élastique 5 par l'intermédiaire du support mobile 3.The spring part of the prestressing means 6 is connected to the mobile support 3 and to the aneroid capsule 10, the spring part transmitting the force or torque from the aneroid capsule 10 to the elastic element 5 via the mobile support 3.

La partie ressort comprend une lame flexible unique 11 reliée perpendiculairement au support rigide 3 du même côté que les lames décroisées 4. La lame flexible unique 11 permet de transmettre la force de précontrainte au support mobile 3 tout en laissant le support mobile 3 libre de tourner.The spring part comprises a single flexible blade 11 connected perpendicularly to the rigid support 3 on the same side as the uncrossed blades 4. The single flexible blade 11 makes it possible to transmit the prestressing force to the mobile support 3 while leaving the mobile support 3 free to rotate .

La partie ressort comprend aussi une table de translation 33 agencée en série entre la paroi mobile 13 et la lame flexible unique 11. La table de translation 33 comprend deux lames flexibles 14 sensiblement parallèles et un élément mobile 12. Les lames flexibles 14 relient l'élément mobile 12 au côté intérieur du petit segment du L de la paroi mobile 13, parallèlement aux grands segments des L.The spring part also comprises a translation table 33 arranged in series between the movable wall 13 and the single flexible blade 11. The translation table 33 comprises two substantially parallel flexible blades 14 and a movable element 12. The flexible blades 14 connect the movable element 12 on the interior side of the small segment of the L of the movable wall 13, parallel to the large segments of the L.

La table de translation 33 a pour fonction de transformer l'écartement de la capsule en force de précontrainte sur le support mobile 3.The function of the translation table 33 is to transform the spacing of the capsule into a prestressing force on the mobile support 3.

L'élément mobile 12 est un parallélépipède relié au support rigide 3 par la lame flexible unique 11, les deux lames flexibles 14 de la table de translation 33 étant agencées perpendiculairement à la lame flexible unique 11. La lame flexible unique 11 s'étend depuis le côté supérieur de l'élément mobile 12 jusqu'au milieu du côté inférieur du support rigide 3.The movable element 12 is a parallelepiped connected to the rigid support 3 by the single flexible blade 11, the two flexible blades 14 of the translation table 33 being arranged perpendicular to the single flexible blade 11. The single flexible blade 11 extends from the upper side of the movable element 12 to the middle of the lower side of the rigid support 3.

Lorsque la pression change, la paroi mobile 13 se rapproche ou s'éloigne de la paroi immobile 15 et du support rigide 3. Ainsi, l'élément mobile 12 de la table de translation subit une force de poussée plus ou moins importante vers le support rigide 3, cette force étant transmise au support rigide 3 via la lame flexible unique 11.When the pressure changes, the movable wall 13 approaches or moves away from the stationary wall 15 and the rigid support 3. Thus, the movable element 12 of the translation table experiences a more or less significant thrust force towards the support rigid 3, this force being transmitted to the rigid support 3 via the single flexible blade 11.

Ainsi, les moyens de précontrainte 6 exercent une force d'écartement variable entre le support rigide 3 et les moyens de fixation 7. En conséquence, la raideur de l'élément élastique 5 varie, et permet d'adapter la marche du balancier aux conditions de pression extérieure pour garder la précision de l'organe réglant.Thus, the prestressing means 6 exert a variable spacing force between the rigid support 3 and the fixing means 7. Consequently, the stiffness of the elastic element 5 varies, and makes it possible to adapt the operation of the balance to the conditions. external pressure to maintain the precision of the regulating organ.

Par exemple, lorsque la pression augmente, la paroi mobile 13 se rapproche de la paroi immobile 15. Ce rapprochement engendre une augmentation de la force d'écartement entre le support rigide 3 et les moyens de fixation 7, qui est exercée par les moyens de précontrainte 6. Ainsi, la raideur de l'élément élastique 5, et donc celle des lames 4 de la paire de lames décroisées est augmentée.For example, when the pressure increases, the movable wall 13 approaches the stationary wall 15. This rapprochement causes an increase in the spacing force between the rigid support 3 and the fixing means 7, which is exerted by the means of prestressing 6. Thus, the stiffness of the elastic element 5, and therefore that of the blades 4 of the pair of uncrossed blades is increased.

Au contraire, lorsque la pression diminue, la paroi mobile 13 s'éloigne de la paroi immobile 15. Cet écartement engendre une diminution de la force d'écartement entre le support rigide 3 et les moyens de fixation 7, qui est exercée par les moyens de précontrainte 6. Ainsi, la raideur de l'élément élastique 5, et donc celle de la paire de lames décroisées 4 est diminuée.On the contrary, when the pressure decreases, the movable wall 13 moves away from the stationary wall 15. This spacing causes a reduction in the spacing force between the rigid support 3 and the fixing means 7, which is exerted by the means prestressing 6. Thus, the stiffness of the elastic element 5, and therefore that of the pair of uncrossed blades 4 is reduced.

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