Description

Oscillateur pour mouvement horloger et pièce d'horlogerie Oscillator for watch movement and timepiece
comportant un tel oscillateur comprising such an oscillator
Domaine technique Technical area
[0001] La présente invention concerne un oscillateur du type balancier- spiral pour mouvement horloger, un mouvement horloger comportant un tel oscillateur ainsi qu'une pièce d'horlogerie comportant un tel mouvement horloger. La présente invention concerne également un dispositif stop- seconde agencé pour coopérer l'oscillateur. The present invention relates to an oscillator of the sprung balance type for a watch movement, a watch movement comprising such an oscillator and a timepiece comprising such a watch movement. The present invention also relates to a stop-seconds device arranged to cooperate with the oscillator.
Etat de la technique State of the art
[0002] Il existe déjà plusieurs oscillateurs se démarquant des oscillateurs traditionnels par leur agencement par rapport au cadran d'une montre procurant ainsi à la montre un aspect visuel original. [0002] Several oscillators already exist which differ from traditional oscillators by their arrangement with respect to the dial of a watch thus providing the watch with an original visual appearance.
[0003] A titre d'exemple, CH713649 divulgue une pièce d'horlogerie comprenant un dispositif de cache ayant au moins un organe mobile et un mécanisme de commande entraînant l'organe mobile entre une position fermée dans laquelle une partie de l'organe réglant, du type balancier-spiral, est cachée par le dispositif de cache, et une position ouverte dans laquelle le balancier-spiral est entièrement visible. L'organe mobile est situé entre le balancier et le spiral lorsqu'il est dans la position fermée. Le dispositif de cache est configuré de sorte à laisser apparaître uniquement le balancier lorsque l'organe mobile est dans une position fermée. A cette fin, le balancier et le spiral sont montés sur l'arbre de balancier de sorte à être séparé d'une distance axiale suffisante pour se situer de part et d'autre de l'organe mobile lorsque celui-ci est dans une position fermée. [0004] EP0520218 divulgue une pièce d'horlogerie comportant un cadran pourvu d'une ouverture dans laquelle est agencé un oscillateur du type balancier-spiral de sorte à ce que l'oscillateur soit agencé sensiblement dans le plan du cadran. [0003] By way of example, CH713649 discloses a timepiece comprising a cover device having at least one movable member and a control mechanism driving the movable member between a closed position in which part of the regulating member , of the sprung balance type, is hidden by the cover device, and an open position in which the sprung balance is fully visible. The movable member is located between the balance and the hairspring when it is in the closed position. The cover device is configured so as to reveal only the balance when the movable member is in a closed position. To this end, the balance and the hairspring are mounted on the balance shaft so as to be separated by a sufficient axial distance to be located on either side of the movable member when the latter is in a position closed. [0004] EP0520218 discloses a timepiece comprising a dial provided with an opening in which is arranged an oscillator of the sprung balance type so that the oscillator is arranged substantially in the plane of the dial.
[0005] DE202012002284U 1 divulgue une pièce d'horlogerie comportant un cadran pourvu d'une ouverture circulaire à l'intérieur de laquelle est monté un mécanisme de tourbillon. Celui-ci comprend un balancier-spiral, un échappement et une roue d'échappement monté dans une cage de tourbillon. Une aiguille d'affichage est montée solidaire de la cage de sorte à être entraîné en rotation à l'intérieur de l'ouverture circulaire au niveau du cadran. Le mécanisme de tourbillon est configuré de sorte à ce que le balancier-spiral soit surélevé par rapport au cadran est oscille au-dessus de l'aiguille d'affichage. [0005] DE202012002284U 1 discloses a timepiece comprising a dial provided with a circular opening inside which a tourbillon mechanism is mounted. This comprises a sprung balance, an escapement and an escape wheel mounted in a tourbillon cage. A display needle is mounted integral with the cage so as to be driven in rotation inside the circular opening at the level of the dial. The tourbillon mechanism is configured so that the sprung balance is raised above the dial and oscillates above the display hand.
[0006] Par ailleurs, il existe de nombreux mécanismes stop-secondes permettant d'arrêter l'aiguille des secondes pour une mise à l'heure précise. [0006] Furthermore, there are many stop-seconds mechanisms making it possible to stop the seconds hand for precise time setting.
[0007] A titre d'exemple, EP1422579 divulgue un système de remise à l'heure comprenant un levier comportant une première partie placée sur une partie supérieure de la platine et une deuxième partie orthogonale avec la première partie et traversant la platine supérieure de façon à venir en contact avec la serge du balancier. [0007] By way of example, EP1422579 discloses a time-setting system comprising a lever comprising a first part placed on an upper part of the plate and a second part orthogonal with the first part and passing through the upper plate so coming into contact with the balance rod.
[0008] Ce système est néanmoins difficile à intégrer au mouvement horloger à cause de la forme du levier dictée par l'emplacement du balancier dans le mouvement. [0008] This system is nevertheless difficult to integrate into the watch movement because of the shape of the lever dictated by the location of the balance in the movement.
[0009] Un but de la présente invention est de proposer un oscillateur du type balancier-spiral selon une construction alternative originale. [0010] Un autre but de la présente invention est de proposer un mouvement horloger dont l'emplacement du balancier permet de simplifier la construction d'un dispositif stop-secondes. An object of the present invention is to provide an oscillator of the sprung balance type according to an original alternative construction. Another object of the present invention is to provide a watch movement whose location of the balance makes it possible to simplify the construction of a stop-seconds device.
[0011] Un autre but de la présente invention est de proposer une pièce d'horlogerie comportant un oscillateur agencé pour conférer à la pièce d'horlogerie un aspect visuel original. Another object of the present invention is to provide a timepiece comprising an oscillator arranged to give the timepiece an original visual appearance.

Le balancier et le spiral sont agencés de part et d'autre de l'organe de transmission. a transmission member arranged to cooperate with an exhaust. The balance and the hairspring are arranged on either side of the transmission member.
[0013] Selon une forme d'exécution, le balancier et le spiral sont montés respectivement à une première et une seconde extrémité de l'arbre de balancier. [0013] According to one embodiment, the balance and the hairspring are mounted respectively at a first and a second end of the balance shaft.
[0014] Selon une forme d'exécution, l'organe de transmission est sous la forme d'un double plateau comportant une cheville destinée à coopérer avec une ancre d'échappement. [0015] Selon une forme d'exécution, l'extrémité interne du spiral est solidaire d'une virole montée à la seconde extrémité de l'arbre de balancier. [0014] According to one embodiment, the transmission member is in the form of a double plate comprising a pin intended to cooperate with an escape anchor. [0015] According to one embodiment, the internal end of the hairspring is integral with a ferrule mounted at the second end of the balance shaft.
[0016] Selon une forme d'exécution, une entretoise est montée sur l'arbre de balancier entre la virole et l'organe de transmission. [0016] According to one embodiment, a spacer is mounted on the balance shaft between the ferrule and the transmission member.
[0017] Un autre aspect de l'invention porte sur un mouvement horloger comportant l'oscillateur tel que décrit ci-dessus. Another aspect of the invention relates to a horological movement comprising the oscillator as described above.
[0018] Selon une forme d'exécution, le mouvement horloger comporte une platine et l'oscillateur est monté dans le mouvement horloger, de sorte à ce que le balancier et le spiral sont agencés de part et d'autre de la platine. [0018] According to one embodiment, the watch movement comprises a plate and the oscillator is mounted in the watch movement, so that the balance and the spring are arranged on either side of the plate.
[0019] Selon une forme d'exécution, le mouvement horloger comporte un cadran et un dispositif stop-secondes disposé intégralement sur la partie supérieure de la platine côté cadran. [0019] According to one embodiment, the watch movement comprises a dial and a stop-seconds device disposed entirely on the upper part of the plate on the dial side.
[0020] Selon une forme d'exécution, le dispositif stop-secondes comporte une bascule montée sur ladite partie supérieure de la platine. La bascule comporte une portion levier agencée pour coopérer avec un pignon-coulant d'un mécanisme de remontoir et une portion d'engagement agencée pour coopérer avec une portion de la serge du balancier.

Exemple(s) de mode de réalisation de l'invention Example (s) of embodiment of the invention
[0024] Selon les Figures 1 et 2, l'oscillateur 10 comporte un balancier 12, un spiral 16 et un arbre de balancier 18. Le balancier 12 comporte une serge 13, un moyeu 15 et plusieurs bras 14 reliant la serge 13 au moyeu 15. Le moyeu 15 du balancier 12 est monté à une première extrémité de l'arbre de balancier 18 au niveau d'un premier segment 18a de l'arbre 18 et contre un épaulement 24 afin d'assurer que le balancier 12 oscille dans un plan perpendiculaire à son axe de rotation. According to Figures 1 and 2, the oscillator 10 comprises a balance 12, a hairspring 16 and a balance shaft 18. The balance 12 comprises a rim 13, a hub 15 and several arms 14 connecting the rim 13 to the hub 15. The hub 15 of the balance 12 is mounted at a first end of the balance shaft 18 at a first segment 18a of the shaft 18 and against a shoulder 24 to ensure that the balance 12 oscillates in a plane perpendicular to its axis of rotation.
[0025] Le spiral 16 est monté à une seconde extrémité de l'arbre de balancier 18 au niveau d'un second segment 18b de l'arbre 18. L'extrémité interne 16a du spiral est solidaire d'une virole 28. La virole 28 est montée sur le second segment 18b de l'arbre de balancier 18 par l'intermédiaire d'une entretoise 26. Celle-ci comporte une première portion 26a possédant un premier diamètre et une seconde portion 26b possédant un second diamètre supérieur au premier diamètre 26a. The hairspring 16 is mounted at a second end of the balance shaft 18 at the level of a second segment 18b of the shaft 18. The inner end 16a of the hairspring is integral with a ferrule 28. The ferrule 28 is mounted on the second segment 18b of the balance shaft 18 by means of a spacer 26. The latter comprises a first portion 26a having a first diameter and a second portion 26b having a second diameter greater than the first diameter 26a.
[0026] La virole 18 est montée sur la première portion 26a de l'entretoise 26, par exemple par chassage ou rivetage, alors que la seconde portion 26b de l'entretoise 26 est agencée entre la virole 18 et un organe de transmission solidaire de l'arbre de balancier 18. Cet organe de transmission est, de préférence, sous la forme d'un double plateau 20 comportant une cheville 22 destinée à coopérer avec une ancre d'échappement (non illustrée) pour réguler la marche d'un mouvement horloger. Selon une forme d'exécution, l'entretoise 26 est formée intégrale avec l'organe de transmission. Dans le mode de réalisation des Figures 1 et 2, le balancier 12 et le spiral 16 sont agencés de part et d'autre de l'organe de transmission. Autrement dit, l'organe de transmission et le spiral 16 sont du même côté du balancier 12. The ferrule 18 is mounted on the first portion 26a of the spacer 26, for example by driving or riveting, while the second portion 26b of the spacer 26 is arranged between the ferrule 18 and a transmission member integral with the balance shaft 18. This transmission member is preferably in the form of a double plate 20 comprising a pin 22 intended to cooperate with an escape anchor (not illustrated) to regulate the rate of a movement watchmaker. According to one embodiment, the spacer 26 is formed integrally with the transmission member. In the embodiment of Figures 1 and 2, the balance 12 and the spring 16 are arranged on either side of the transmission member. In other words, the transmission member and the spring 16 are on the same side of the balance 12.
[0027] Les Figures 3 à 5 montrent un mouvement horloger comportant une platine 80. L'oscillateur est monté dans le mouvement horloger 80, de sorte à ce que le balancier 12 et le spiral 16 soient agencés de part et d'autre de la platine 80. Par exemple, le balancier 12 est arrangé du côté affichage de la platine 80 et le spiral est arrangé du côté opposé (côté fond) de la platine 80. Dans l'exemple de la Figure 3, le mouvement horloger comporte un cadran 70. L'oscillateur 10 est monté dans le mouvement horloger de sorte à ce que le balancier 12 soit agencé au niveau du cadran 70, par exemple dans une ouverture circulaire 72 réalisée sur le cadran 70. Le balancier 12 peut également être agencé au-dessus du cadran 70. Le spiral 16 est, quant à lui, agencé du côté opposé de la platine. Par exemple, le spiral 16 est agencé de sorte à se trouver côté fond d'une boite de montre (non illustrée) lorsque le mouvement est incorporé dans la boite de montre d'une pièce d'horlogerie. Selon une variante, la pièce d'horlogerie est dépourvu de cadran ou comporte uniquement un cadran partiel avec une découpe en arc de cercle de sorte à entourer que partiellement le balancier du mouvement. Figures 3 to 5 show a watch movement comprising a plate 80. The oscillator is mounted in the watch movement 80, so that the balance 12 and the hairspring 16 are arranged on either side of the plate 80. For example, the balance 12 is arranged on the display side of the plate 80 and the hairspring is arranged on the opposite side (back side) of the plate 80. In the example of Figure 3, the watch movement comprises a dial 70. The oscillator 10 is mounted in the watch movement so that the balance 12 is arranged at the level of the dial 70, for example in a circular opening 72 made on the dial 70. The balance 12 can also be arranged at the- above the dial 70. The hairspring 16 is, for its part, arranged on the opposite side of the plate. For example, the hairspring 16 is arranged so as to be on the bottom side of a watch case (not shown) when the movement is incorporated in the watch case of a timepiece. According to a variant, the timepiece does not have a dial or only has a partial dial with a cutout in an arc of a circle so as to only partially surround the balance of the movement.
[0028] Les extrémités de l'arbre de balancier 18 sont montées dans un premier et un second palier (non visibles) agencés respectivement sur un premier et un second pont de balancier 30, 36 montés sur la platine 80 coté cadran et coté fond respectivement. Les extrémités du premier pont de balancier 32 sont fixées à la platine 80 par deux vis 34. Ces vis sont également vissées dans deux cylindres de fixation 33 agencés entre les extrémités du premier pont de balancier 30 et la platine 80. La hauteur des cylindres de fixation 33 a été ajustée de sorte à ce que la balancier 12 de l'oscillateur 10 soit agencé dans l'ouverture 72 au niveau du cadran 70. Notons qu'une décoration peut être usinée sur le premier pont de balancier 30, du côté cadran, afin d'améliorer l'aspect esthétique du mouvement horloger comprenant l'oscillateur 10. The ends of the balance shaft 18 are mounted in a first and a second bearing (not visible) arranged respectively on a first and a second balance bridge 30, 36 mounted on the plate 80 on the dial side and bottom side respectively . The ends of the first balance bridge 32 are fixed to the plate 80 by two screws 34. These screws are also screwed into two fixing cylinders 33 arranged between the ends of the first balance bridge 30 and the plate 80. The height of the cylinders of fixing 33 has been adjusted so that the balance 12 of oscillator 10 is arranged in the opening 72 at the level of the dial 70. It should be noted that a decoration can be machined on the first balance bridge 30, on the dial side, in order to improve the aesthetic appearance of the watch movement comprising the oscillator 10.
[0029] Selon la Figure 5, le second pont de balancier 36 comporte un porte porte-piton 38 dans lequel est fixé un piton 17 solidaire de l'extrémité externe du spiral 16. Un système de raquetterie est en outre monté sur le second pont de balancier 36. Le système de raquetterie comporte une raquette 39 pour l'ajustement de la longueur active du spiral 16 afin de corriger des écarts de marche au cours d'un contrôle qualité. La raquette 39 comprend à cet effet un bras supportant une goupille 39a muni d'une fente à l'intérieur de laquelle un segment du spiral 16 est agencé. La raquette 39 est ajustée à frottement gras sur le second pont de balancier 36. Comme visible dans les Figures 4 et 5, il est prévu dans la platine 80 un dégagement 81 permettant le passage de l'oscillateur 10 lors du montage de ce dernier dans le mouvement. Le dégagement 81 a une forme demi circulaire, ouverte à la périphérie de la platine 80 mais peut avoir également toute autre forme appropriée à l'assemblage de l'oscillateur 10 dans le mouvement. According to Figure 5, the second balance bridge 36 comprises a pin holder 38 in which is fixed a pin 17 integral with the outer end of the hairspring 16. A snowshoe system is also mounted on the second bridge balance 36. The snowshoe system comprises a racket 39 for adjusting the active length of the hairspring 16 in order to correct rate deviations during quality control. The racket 39 comprises for this purpose an arm supporting a pin 39a provided with a slot inside which a segment of the hairspring 16 is arranged. The racket 39 is adjusted with greasy friction on the second balance bridge 36. As visible in Figures 4 and 5, there is provided in the plate 80 a clearance 81 allowing the passage of the oscillator 10 during assembly of the latter in movement. The clearance 81 has a semi-circular shape, open to the periphery of the plate 80 but can also have any other shape suitable for the assembly of the oscillator 10 in the movement.
[0030] Selon les Figures 6a, 6b, le mouvement horloger comporte un dispositif stop-secondes coopérant avec la tige de remontoir 40 du mouvement horloger. Le dispositif stop-secondes comporte une bascule 50 qui a l'avantage d'être agencée dans une fraisure 59 réalisée sur la platine supérieure 80 côté cadran, ce qui simplifie l'intégration du dispositif stop- secondes dans le mouvement horloger. According to Figures 6a, 6b, the watch movement comprises a stop-seconds device cooperating with the winding stem 40 of the watch movement. The stop-seconds device comprises a rocker 50 which has the advantage of being arranged in a countersink 59 made on the upper plate 80 on the dial side, which simplifies the integration of the stop-seconds device in the watch movement.
[0031] La bascule 50 est montée pivotante autour d'un tenon 58 à l'intérieur de la fraisure 50. Cette bascule est réalisée par un assemblage deux pièces distinctes, un levier 52 agencé pour coopérer avec la tige de remontoir 40 et un bras d'engagement 56 comportant à son extrémité distale un sabot 57 agencé pour venir en butée contre une partie du pourtour de la serge 13 du balancier 12 lorsque le dispositif stop-secondes est actionné. The rocker 50 is pivotally mounted around a tenon 58 inside the countersink 50. This rocker is produced by an assembly of two separate parts, a lever 52 arranged to cooperate with the winding stem 40 and an engagement arm 56 comprising at its distal end a shoe 57 arranged to abut part of the periphery of the rim 13 of the balance 12 when the stop-seconds device is actuated.
[0032] Le bras d'engagement 56 est connecté au levier 52 de la bascule 50 de sorte à basculer dans un plan parallèle au plan dans lequel le levier 52 est agencé. A cette fin, une entretoise 60 est montée entre le levier 52 et le bras d'engagement 56 de sorte à ce que le sabot 57 du bras d'engagement se trouve à la même hauteur que le balancier 12. Par ailleurs, le bras d'engagement 56 et le levier de la bascule 50 sont agencés de part et d'autre du tenon 58 autour duquel pivote la bascule 50 et forment entre eux un angle situé entre 30° et 60°. Selon une variante, la bascule 50 est formée d'une seule pièce comportant une portion d'engagement et une portion levier. Selon une forme d'exécution, l'entretoise 60 est formé intégrale avec le levier 52 et le bras d'engagement 56. The engagement arm 56 is connected to the lever 52 of the rocker 50 so as to switch in a plane parallel to the plane in which the lever 52 is arranged. To this end, a spacer 60 is mounted between the lever 52 and the engagement arm 56 so that the shoe 57 of the engagement arm is at the same height as the balance 12. Furthermore, the arm d 'engagement 56 and the lever of the rocker 50 are arranged on either side of the tenon 58 around which the rocker 50 pivots and form between them an angle between 30 ° and 60 °. According to a variant, the rocker 50 is formed in a single piece comprising an engagement portion and a lever portion. According to one embodiment, the spacer 60 is formed integrally with the lever 52 and the engagement arm 56.
[0033] Le levier 52 de la bascule 50 est en prise avec un pignon coulant 46 agencé contre le pignon de remontoir 44 au cours de la marche du mouvement horloger. L'extrémité distale du levier 52 comporte un doigt 54 agencé pour coopérer avec une tirette 42 du mécanisme de remontoir du mouvement horloger. La tirette 42 est agencé pour pivoter autour de son axe de pivotement lorsque la tige de remontoir 40 est actionnée d'une première position axiale à une seconde position axiale correspondant à la position pour le réglage de l'heure. The lever 52 of the rocker 50 is engaged with a sliding pinion 46 arranged against the winding pinion 44 during the running of the watch movement. The distal end of the lever 52 comprises a finger 54 arranged to cooperate with a pull tab 42 of the winding mechanism of the watch movement. The pull tab 42 is arranged to pivot about its pivot axis when the winding stem 40 is actuated from a first axial position to a second axial position corresponding to the position for setting the time.
[0034] Le pivotement de la tirette 42 exerce une force contre le doigt 54 de la bascule 50 afin d'entraîner celle-ci en rotation autour du tenon 58. Le pivotement de de la bascule 50 permet, d'une part, d'amener le sabot 57 de la portion d'engagement 56 en butée contre une portion du pourtour de la serge 13 du balancier 12 afin d'immobiliser le balancier et, d'autre part, d'éloigner le pignon coulant 46 du pignon de remontoir 44 jusqu'à ce qu'il engrène avec les renvois et la minuterie pour la commande des aiguilles pour la mise à l'heure du mouvement. The pivoting of the zipper 42 exerts a force against the finger 54 of the lever 50 in order to cause it to rotate around the tenon 58. The pivoting of the lever 50 allows, on the one hand, to bring the shoe 57 of the engagement portion 56 into abutment against a portion of the periphery of the rim 13 of the balance 12 in order to immobilize the balance and, on the other hand, move the sliding pinion 46 away from the winding pinion 44 until it meshes with the references and the timer for controlling the hands for setting the time of the movement.
