Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

L'invention concerne le domaine des montres mécaniques à performances chronométriques élevées.The invention relates to the field of mechanical watches with high chronometric performance.

Pour améliorer l'insensibilité aux positions d'une montre 1000, il est connu de l'équiper d'un dispositif limiteur 100 d'horlogerie, comportant un oscillateur 200, et comportant des moyens pour la limitation de l'écart de marche de cet oscillateur 200 dans les différentes positions de la montre 1000 dans l'espace.To improve the insensitivity to the positions of a watch 1000, it is known to equip it with a clock limiting device 100, comprising an oscillator 200, and comprising means for limiting the rate deviation of this oscillator 200 in the various positions of the watch 1000 in space.

Ce dispositif 100 comporte au moins un tourbillon 300 ou un carrousel, qui, dans l'un ou l'autre cas, comporte une cage 10 qui est montée pivotante autour d'un axe de cage D par rapport à une platine 900.This device 100 comprises at least one tourbillon 300 or a carousel, which, in either case, comprises a cage 10 which is mounted to pivot about a cage axis D relative to a plate 900.

Cette platine 900 est porteuse d'une roue fixe 210 quand le dispositif limiteur 100 comporte un tourbillon 300.This plate 900 carries a fixed wheel 210 when the limiting device 100 includes a tourbillon 300.

La cage 10 porte l'oscillateur 200, et comporte une roue de cage 5, qui est agencée pour être entraînée par une source d'énergie 400 de la montre 1000 ou d'un mouvement 800 que comporte la montre, au travers d'un rouage. Cette source d'énergie 400 peut notamment comporter au moins un barillet ou similaire.The cage 10 carries the oscillator 200, and comprises a cage wheel 5, which is arranged to be driven by a power source 400 of the watch 1000 or of a movement 800 that the watch includes, through a cog. This energy source 400 can in particular include at least one barrel or the like.

La cage 10 porte encore un mécanisme d'échappement 700, qui est agencé pour coopérer avec l'oscillateur 200, et qui comporte un pignon d'échappement 201. La cage 10 comporte un pont inférieur 11 et un pont supérieur 12. Le pont supérieur de cage 12 protège à la fois l'oscillateur 200, le mécanisme d'échappement 700, et le mécanisme selon l'invention.The cage 10 also carries an escape mechanism 700, which is arranged to cooperate with the oscillator 200, and which comprises an escape pinion 201. The cage 10 comprises a lower bridge 11 and an upper bridge 12. The upper bridge cage 12 protects both the oscillator 200, the escape mechanism 700, and the mechanism according to the invention.

Plus particulièrement, le dispositif 100 comporte des moyens de mise à l'heure 500 qui constituent ou qui commandent l'organe de commande, lequel est agencé pour mouvoir la tringle de commande 30 dans un premier sens d'activation lors du passage des moyens de mise à l'heure 500 d'une position de repos T1 à une position activée T2, et pour mouvoir la tringle de commande 30 dans un deuxième sens contraire au premier sens lors du passage des moyens de mise à l'heure 500 de la position activée T2 à la position de repos T1.More particularly, the device 100 comprises time-setting means 500 which constitute or which control the control member, which is arranged to move the control rod 30 in a first direction of activation during the passage of the control means. setting the time 500 from a rest position T1 to an activated position T2, and to move the control rod 30 in a second direction opposite to the first direction during the passage of the time-setting means 500 from the position activated T2 at rest position T1.

Dans une variante, tel que visible sur les figures 1 à 4, la lame-ressort comporte une surface d'appui lisse, en portion cylindrique, de même rayon que le diamètre extérieur de la roue de cage 5.In a variant, as seen on the figures 1 to 4 , the leaf spring has a smooth bearing surface, in a cylindrical portion, with the same radius as the outside diameter of the cage wheel 5.

Dans une autre variante, tel que visible sur la figure 5, la lame élastique 4 comporte une denture 41 agencée pour coopérer en engrènement avec la denture de la roue de cage 5.In another variant, as seen on the figure 5 , the elastic blade 4 comprises a set of teeth 41 arranged to cooperate in mesh with the teeth of the cage wheel 5.

Plus particulièrement, la lame élastique 4 s'étend en porte-à-faux par rapport à sa fixation sur la tringle de commande 30.More particularly, the elastic blade 4 extends overhanging with respect to its attachment to the control rod 30.

Dans une variante, la lame élastique 4 présente une surface convexe du côté de la cage 10.In a variant, the elastic blade 4 has a convex surface on the side of the cage 10.

Dans une autre variante, la lame élastique 4 présente une surface concave du côté de la cage 10.In another variant, the elastic blade 4 has a concave surface on the side of the cage 10.

Plus particulièrement, l'oscillateur 200 est un ensemble balancier-spiral.More particularly, the oscillator 200 is a balance-spring assembly.

L'invention concerne encore une montre 1000 comportant un mouvement d'horlogerie 800 comportant des moyens de stockage d'énergie 400, un oscillateur 200, des moyens de mise à l'heure 500, et un tel dispositif limiteur 100.The invention also relates to a watch 1000 comprising a clockwork movement 800 comprising energy storage means 400, an oscillator 200, time-setting means 500, and such a limiting device 100.

Plus particulièrement, le tourbillon 300 ou carrousel constitue un organe d'affichage de la montre 1000 ou est agencé pour entraîner au moins un organe d'affichage de la montre 1000, et les moyens de mise à l'heure 500 constituent ou commandent l'organe de commande.More particularly, the tourbillon 300 or carousel constitutes a display member of the watch 1000 or is arranged to drive at least one display member of the watch 1000, and the time-setting means 500 constitute or control the control unit.

Dans la variante non limitative illustrée par les figures, des moyens de mise à l'heure 500 constituent ou commandent l'organe de commande, et comportent une tige de remontage et de mise à l'heure 1 classique, et le fonctionnement est le suivant :

  • en position T1, la tige de remontage et de mise à l'heure 1 positionne la tirette 2, sur laquelle est chassé un grand plot 24. Ce plot 24 est en contact avec la tringle de commande 3 par l'intermédiaire d'une ganse 34. La tringle de commande 3 est guidée par la coopération de deux goupilles 320 et 330 fixées à la platine 900 et de deux oblongs 32 et 33 que comporte la tringle 3, pour se déplacer de façon linéaire. Elle porte une lame-ressort 4 qui est dans le même plan que la roue de cage 5. Cette roue de cage 5 est solidaire de la cage 10. Le système est fixe dans la position ci-dessous en T1 ;
  • en passant de T1 à T2, la tige de remontage et de mise à l'heure 1 fait pivoter la tirette 2 qui elle-même fait descendre la tringle de commande 3 en direction de la cage 10. La lame-ressort 4 vient alors en contact sur la denture de la roue de cage 5 ce qui provoque l'arrêt de la cage.
In the non-limiting variant illustrated by the figures, time-setting means 500 constitute or control the control member, and comprise a conventional winding and time-setting rod 1, and the operation is as follows :
  • in position T1, the winding and time-setting rod 1 positions the zipper 2, on which is driven a large stud 24. This stud 24 is in contact with the control rod 3 by means of a strap 34. The control rod 3 is guided by the cooperation of two pins 320 and 330 fixed to the plate 900 and two oblongs 32 and 33 which the rod 3 comprises, in order to move in a linear fashion. It carries a leaf spring 4 which is in the same plane as the cage wheel 5. This cage wheel 5 is integral with the cage 10. The system is fixed in the position below at T1;
  • going from T1 to T2, the winding and time-setting rod 1 rotates the zipper 2 which itself lowers the control rod 3 in the direction of the cage 10. The leaf spring 4 then comes in contact on the teeth of the cage wheel 5 which causes the cage to stop.

Le système est conçu pour stopper le tourbillon, ou respectivement le carrousel, en mise à l'heure.The system is designed to stop the tourbillon, or the carrousel respectively, in setting the time.

Le système vient s'appuyer sur la roue de cage avec une lame-ressort qui effectue une pression suffisante pour stopper la cage.The system rests on the cage wheel with a leaf spring which applies sufficient pressure to stop the cage.

En somme, l'invention permet de :

  • stopper instantanément une cage de tourbillon ou de carrousel ;
  • effectuer une mise à l'heure à la seconde près.
In short, the invention makes it possible to:
  • instantly stop a tourbillon or carousel cage;
  • set the time to the nearest second.

Ce mécanisme à roue d'arrêt intégré est compact, sa fabrication relève de technologies usuelles, et son coût est donc modéréThis integrated locking wheel mechanism is compact, its manufacture is based on conventional technologies, and its cost is therefore moderate.
