TECHNIQUE ANTERIEUREPRIOR ART

De nombreux mouvements d'horlogerie mécaniques conventionnels comportent un organe de régulation réalisé sous la forme d'un ensemble balancier-spiral, cet ensemble étant formé d'un balancier et d'un ressort spiral.Many conventional mechanical watch movements include a regulating member produced in the form of a balance-spring assembly, this assembly being formed of a balance and a spiral spring.

Les balanciers conventionnels sont formés d'une serge, d'un axe de balancier et de bras reliant la serge à l'axe de balancier. Les bras et la serge sont dans le même plan. Le ressort spiral est disposé généralement dans un plan, parallèle au plan de la serge et des bras.Conventional pendulums are formed by a serge, a pendulum axis and arms connecting the serge to the pendulum axis. The arms and the serge are in the same plane. The spiral spring is generally arranged in a plane, parallel to the plane of the twill and the arms.

Dans certaines réalisations, le ressort spiral peut avoir une forme cylindrique, conique ou sphérique.In certain embodiments, the spiral spring may have a cylindrical, conical or spherical shape.

Lorsque le ressort spiral est plan et qu'il est placé dans le même plan que la serge et les bras, le centre de gravité de l'ensemble balancier-spiral se trouve également dans le même plan, sur l'axe de rotation du balancier.When the spiral spring is plane and it is placed in the same plane as the serge and the arms, the center of gravity of the balance-spring assembly is also in the same plane, on the axis of rotation of the balance .

Dans certaines configurations, il pourrait être intéressant et avantageux de pouvoir choisir la position du centre de gravité de l'ensemble balancier-spiral le long de l'axe de rotation du balancier, sans devoir ajouter des pièces supplémentaires qui ajoutent de la masse et de la complexité. Un tel réglage du centre de gravité peut être recherché notamment lorsque l'ensemble balancier-spiral est utilisé dans un système réglant tel que par exemple un tourbillon ou un carrousel.In certain configurations, it could be advantageous and advantageous to be able to choose the position of the center of gravity of the balance-spring assembly along the axis of rotation of the balance, without having to add additional parts which add mass and the complexity. Such a center of gravity adjustment can be sought in particular when the balance-spring assembly is used in a regulating system such as for example a tourbillon or a carousel.

MANIERE DE REALISER L'INVENTIONMANNER OF CARRYING OUT THE INVENTION

En référence aux figures, le mouvement d'horlogerie selon la présente invention est destiné à être placé dans un boîtier (non représenté) d'une pièce d'horlogerie telle que notamment une montre de type montre-bracelet. Une telle pièce d'horlogerie comporte, de façon conventionnelle, une platine supportant notamment un système moteur ayant une source d'énergie, et un rouage formé d'engrenages entraînés en rotation par le système moteur. La platine supporte en outre un organe de régulation réalisé sous la forme d'un ensemble balancier-spiral 10, cet ensemble balancier-spiral 10 étant illustré par les figures 1 à 4.With reference to the figures, the timepiece movement according to the present invention is intended to be placed in a case (not shown) of a timepiece such as in particular a watch of the wristwatch type. Such a timepiece conventionally comprises a plate supporting in particular a motor system having a power source, and a cog formed of gears driven in rotation by the motor system. The plate further supports a regulating member produced in the form of a balance-spring 10, this balance-spring 10 assembly being illustrated by the figures 1 to 4 .

L'ensemble balancier-spiral 10 comporte d'une part un balancier 11 et d'autre part un ressort spiral 12. Le balancier 11 est formé d'une serge 13, d'un axe de balancier 14 et de bras 15 reliant la serge 13 à l'axe de balancier 14. En fonctionnement, le balancier 11 pivote alternativement autour de l'axe de balancier 14, sous l'effet du ressort spiral 12.The balance-spring assembly 10 comprises a balance 11 on the one hand and a spiral spring 12 on the other hand. The balance 11 is formed by a clamp 13, a balance pin 14 and arms 15 connecting the clamp 13 to the balance axis 14. In operation, the balance 11 alternately pivots around the balance axis 14, under the effect of the spiral spring 12.

Les bras 15 du balancier 11 sont fixés à l'axe de balancier 14. Cette fixation peut se faire au moyen d'une liaison fixe tel qu'un rivetage. Les bras 15 peuvent également être chassés sur l'axe de balancier 14 ou être fixés au moyen d'une bague 16 vissée sur l'axe de balancier 14.The arms 15 of the pendulum 11 are fixed to the pendulum axis 14. This fixing can be done by means of a fixed link such as riveting. The arms 15 can also be driven out on the balance axis 14 or be fixed by means of a ring 16 screwed onto the balance axis 14.

Contrairement aux balanciers conventionnels, les bras 15 ne sont pas plans et disposés dans un plan dans lequel se trouve la serge 13. Ces bras 15 ont une forme courbée ou arquée et sont fixés à l'axe de balancier 14 dans une zone située hors du plan de la serge 13. Cette forme arquée des bras 15 permet de définir un logement limité par une enveloppe formée par les bras 15 et par le plan dans lequel est placé la serge 13.Unlike conventional pendulums, the arms 15 are not planar and arranged in a plane in which the serge 13 is located. These arms 15 have a curved or arcuate shape and are fixed to the pendulum axis 14 in an area outside the plane of the serge 13. This arched shape of the arms 15 makes it possible to define a housing limited by an envelope formed by the arms 15 and by the plane in which the serge 13 is placed.

Une extrémité 17 du ressort spiral 12 est fixée à l'axe de balancier 14, comme mentionné précédemment. Cette fixation est faite à l'intérieur du logement défini par les bras 15 et la serge 13.One end 17 of the spiral spring 12 is fixed to the pendulum axis 14, as mentioned previously. This fixing is made inside the housing defined by the arms 15 and the twill 13.

Une autre extrémité 18 du ressort spiral 12 est fixée à un coq (non représenté) par l'intermédiaire d'un piton, de façon conventionnelle.Another end 18 of the spiral spring 12 is fixed to a cock (not shown) by means of a stud, in a conventional manner.

Le choix de la forme des bras 15 et de la position de fixation du ressort spiral 12 sur l'axe de balancier 14 permet de choisir la position du centre de gravité de l'ensemble balancier-spiral 10 le long de l'axe de rotation du balancier.The choice of the shape of the arms 15 and of the fixing position of the balance spring 12 on the balance axis 14 makes it possible to choose the position of the center of gravity of the balance balance spring 10 along the axis of rotation. pendulum.

Le logement défini par l'enveloppe des bras 15 et la serge 13 permet de recevoir un ressort spiral 12 ayant une forme cylindrique ou sphérique notamment.The housing defined by the envelope of the arms 15 and the serge 13 makes it possible to receive a spiral spring 12 having a cylindrical or spherical shape in particular.

L'ensemble balancier-spiral 10 peut ainsi être facilement adapté ou modifié pour choisir la position du centre de gravité de cet ensemble. Ce dernier a par ailleurs un aspect esthétique particulier, original et attrayant.The balance-spring assembly 10 can thus be easily adapted or modified to choose the position of the center of gravity of this assembly. The latter also has a particular aesthetic aspect, original and attractive.
