Description

  • La présente invention est relative à une masse oscillante destinée au remontage automatique d'un mouvement d'horlogerie, la masse étant à pivotement décentré par rapport au centre du mouvement et étant réalisée en un seul matériau lourd. The present invention relates to a rotor intended for the automatic winding of a timepiece movement, the mass being eccentric pivoting movement relative to the center and being made of a single heavy material.
  • Lorsqu'il s'agit d'une montre à remontage automatique traditionnelle, le remontage est généralement assuré par la rotation d'une masse oscillante d'un rayon approximativement égal à celui du mouvement et pivotant au centre et au dessus de ce dernier. In the case of a watch with traditional automatic winding, the winding is generally provided by rotation of a rotor with a radius approximately equal to that of movement and pivoting in the center and above the latter. Dans ce cas, la masse oscillante est normalement constituée de deux parties distinctes: le support de masse et le secteur lourd. In this case, the rotor normally consists of two distinct parts: the mass carrier and the construction sector. Le support de masse porte le secteur lourd sur son pourtour et, en son centre, est pivoté sur un arbre qui constitue la suspension de toute la masse oscillante. Mass holder carries the heavy sector at its periphery and at its center, is pivoted on a shaft which constitutes the suspension of the oscillating mass. Ce support est généralement fait en laiton ou en maillechort et est volontairement rendu flexible pour ne pas endommager la suspension de la masse oscillante en cas de choc. This support is usually made of brass or nickel silver and is deliberately made flexible to avoid damaging the suspension of the oscillating weight on impact. Ici le support de masse joue le rôle d'un amortisseur de choc. Here the mass media acts as a shock absorber.
  • Une manière de rendre flexible le support de masse est décrite dans l'exposé d'invention One way to make flexible the mass holder is described in the statement of invention CH-279 001 CH-279001 . . Ici le secteur lourd est supporté par au moins deux bras élastiques, pivotés en un même point du bâti, de manière que les chocs axiaux subis par la masse soient absorbés par l'élasticité de ces bras. Here the construction sector is supported by at least two resilient arms, pivoted at a same point of the frame, so that the axial shocks to the mass to be absorbed by the elasticity of the arms.
  • Le secteur lourd d'un système traditionnel à grand rayon est la partie extérieure de la masse oscillante et est solidaire du support de masse auquel il est fixé par vissage, rivetage ou encore sertissage. The construction sector of a traditional system with a large radius is the outer part of the rotor and is secured to the mass holder to which it is fixed by screwing, riveting or crimping. Il est constitué d'alliage frité ou de métal précieux de grande masse volumique. It consists of frit alloy or high density precious metal.
  • Lors d'un choc de faible intensité, l'élasticité du support de masse suffit à protéger le système de l'impact. During an impact of low intensity, the elasticity of the mass holder is sufficient to protect the system from the impact. En cas de choc de forte intensité, le déplacement de la masse oscillante est limité par l'appui du secteur lourd sur la platine dans un sens et sur le fond de la boîte dans l'autre sens. In case of shock of high intensity, displacement of the oscillating mass is limited by the support of the construction area on the plate in one direction and on the bottom of the box in the other direction. Le support de masse, souvent décoré, ne risque donc pas d'être rayé. The mass media, often decorated, so do not risk being scratched.
  • On a cependant déjà proposé de limiter l'ébat de la masse par des butées ajustées dans la masse oscillante et présentant des parties arrondies et polies faisant saillie par rapport à la surface de ladite masse, de telle sorte qu'en cas de chocs brusques, cette masse n'arrive pas à toucher le fond de la boîte ni le dessus de la platine. However, it has already been proposed to limit the shake of the mass by stops fitted into the oscillating weight and having rounded and polished portions projecting with respect to the surface of said mass, so that in case of sudden shocks, this mass can not touch the bottom of the can or the top of the deck. Une telle réalisation est décrite dans le brevet Such an embodiment is described in patent CH-331 275 CH-331 275 . .
  • Comme la présente invention concerne une masse oscillante à pivotement décentré par rapport au centre du mouvement, telle que décrite par exemple dans la demande de brevet Since the present invention relates to a rotor pivotally offset from the center of motion, as described for example in patent application CH 9.431/66 CH 9431/66 , les remèdes décrits pour contrecarrer les effets néfastes des chocs appliqués à la pièce d'horlogerie ne conviennent pas, car le rayon de la masse oscillante est fortement réduit par rapport à celui d'une masse oscillante traditionnelle pour former ce qu'on peut appeler un micro-rotor. The remedies described to counteract the adverse effects of shocks applied to the timepiece are not suitable, because the radius of the rotor is greatly reduced compared to that of a conventional rotor to form what can be called a micro-rotor. Ce micro-rotor est intégré au mouvement et par conséquent ne le surplombe pas, ce qui conduit dans la plupart des cas à une diminution d'épaisseur de la pièce d'horlogerie. This micro-rotor movement is integrated and therefore not overlooking, leading in most cases to a reduction in thickness of the timepiece.
  • Etant donné que le moment d'inertie d'une masse oscillante dépend de son rayon, de son épaisseur et de sa matière, la perte engendrée par la réduction de rayon observée sur le micro-rotor doit être compensée par une augmentation de son épaisseur. Since the moment of inertia of a rotor depends on its radius, thickness and its material, the loss generated by the radius reduction observed in the micro-rotor must be compensated by an increase in its thickness. En conséquence, le micro-rotor va présenter une grande épaisseur et sera réalisé d'un seul bloc en un seul matériau lourd faisant disparaître ainsi le support de masse élastique dont il a été question plus haut. Accordingly, the micro-rotor will have a greater thickness and is made of a single block of a single heavy material thereby removing the elastic mass support which has been discussed above. Le système ne présentant alors plus l'élasticité requise, la suspension autour de laquelle est articulé le micro-rotor subit en totalité la contrainte causée par un choc appliqué à la masse oscillante et risque d'être endommagée. The system then no longer having the required elasticity, suspension around which is hinged micro-rotor undergoes completely the stress caused by a shock applied to the oscillating weight and may be damaged.
  • Une partie du choc en question pourrait être compensé en augmentant le jeu axial du rotor sur son arbre, mais alors la face du rotor se trouvant en regard du fond de la pièce d'horlogerie pourrait entrer en contact avec ce fond et être endommagée ainsi que le décor susceptible d'y être apposé. Some of the shock in question could be compensated by increasing the axial play of the rotor on its shaft, but then the face of the rotor lying opposite the bottom of the timepiece may come in contact with this bottom and be damaged and the decoration may be affixed.
  • Pour remédier aux inconvénients cités ci-dessus, la présente invention, a pour objet un mouvement d'horlogerie défini par la revendication 1 du brevet. To remedy the drawbacks mentioned above, the present invention relates to a timepiece movement defined by claim 1 of the patent.
  • L'invention va être expliquée maintenant en détail ci-dessous au moyen de dessins de principe d'une part et d'autre part au moyen de dessins illustrant un mode de réalisation particulier, ce dernier étant donné à titre d'exemple non limitatif, dessins dans lesquels : The invention will now be explained in detail below by means of principle drawings one hand and on the other hand by means of the drawings illustrating a particular embodiment, the latter being given by way of non-limiting example, drawings in which:

  • Les The figures 1 et 2 Figures 1 and 2 sont des coupes simplifiées montrant un amortisseur . are simplified sections showing a damper. Elles montrent une masse oscillante 2 destinée au remontage automatique d'un mouvement 3 d'horlogerie lequel est brièvement esquissé en They show an oscillating mass 2 for the automatic winding of a timepiece movement 3 which is briefly outlined in figure 5 Figure 5 . . La masse 2 est à pivotement décentré par rapport au centre du mouvement, est intégrée à ce mouvement et est réalisée en un seul matériau lourd. The mass 2 is off-centered pivot with respect to the center of motion, is integrated to this movement and is performed in a single construction material. Comme le montre bien les As highlighted in the figures 1 et 2 Figures 1 and 2 et selon une caractéristique importante de l'invention, la masse 2 est supportée par un amortisseur de choc 1 qui se présente sous la forme d'une plaque 4 dont une extrémité est fixée à cette plaque (à l'endroit marqué par un X) et dont une autre extrémité est fixée ou est solidaire d'un tube 5, ce dernier étant arrangé pour tourner autour d'un arbre 6 constituant l'axe 7 de rotation de ladite masse. and according to an important characteristic of the invention, the mass 2 is supported with a 1 shock absorber which is in the form of a plate 4 having one end fixed to this plate (at the location marked by an X) and another end is fixed or is integral with a tube 5, the latter being arranged to rotate about a shaft 6 constituting the axis 7 of rotation of said mass.
  • Ainsi, lors d'un choc, ce dernier est absorbé dans sa plus grande partie par l'amortisseur 1, ce qui préserve ainsi l'intégrité de l'arbre 6 autour duquel tourne la masse 2, la suspension de la masse ne subissant plus la totalité de la contrainte provoquée par ce choc et ne risquant plus d'être endommagée. Thus, upon impact, it is absorbed in the most part by the damper 1, which thus preserves the integrity of the shaft 6 around which the mass 2, the suspension of the mass undergoing more all of the stress caused by the shock and risk from being damaged.
  • La partie gauche de la The left side of the figure 1 figure 1 présente la masse oscillante 2 dans sa situation normale, c'est-à-dire quand la pièce d'horlogerie n'est affectée d'aucun choc. this oscillating weight 2 in its normal position, that is to say when the timepiece is not affected by any shock. La partie droite de la The right side of the figure 1 figure 1 présente la situation de la masse oscillante 2 lorsque la pièce d'horlogerie subit un choc dirigé axialement dans le sens de la flèche A. La masse 2 s'est affaissée d'une distance - h par rapport à sa position normale, amenant la plaque 4 à fléchir et à jouer son rôle d'amortisseur 1 comme le montre la presents the situation of the rotor 2 when the timepiece is impacted directed axially in the direction of arrow A. The mass 2 collapsed a distance - h relative to its normal position, causing the plate 4 to flex and play its role of shock absorber 1 as shown figure 1 figure 1 . .
  • La partie gauche de la The left side of the figure 2 Figure 2 présente la même masse oscillante 2 en situation normale, la pièce d'horlogerie n'étant affectée d'aucun choc. has the same rotor 2 in normal situation, the timepiece being affected by any shock. La partie droite de la The right side of the figure 2 Figure 2 présente la situation de la masse 2 lorsque la pièce d'horlogerie subit un choc dirigé axialement et dans le sens de la flèche B, opposé au sens de la flèche A. La masse 2 s'est soulevée d'une distance + h par rapport à sa position normale, amenant la plaque 4 à fléchir et à jouer à nouveau son rôle d'amortisseur 1 comme le montre la presents the situation of the mass 2 when the timepiece is impacted axially directed and in the direction of arrow B, opposite to the direction of arrow A. The mass 2 is raised by a distance h with respect + to its normal position, causing the plate 4 to flex and play again the shock absorber 1 as shown in figure 2 Figure 2 . .
  • Dans les deux cas de figures, on remarquera que le tube 5 ne subit aucun déplacement axial lors de chocs, retenu qu'il est par construction et comme on le verra à propos de la In both scenarios, it is noted that the tube 5 does not undergo any axial movement during impacts, it is retained by construction and as will be seen about the figure 6 Figure 6 . .
  • Comme on le verra également en As will also be seen in figure 6 Figure 6 , on préférera disposer la plaque 4 servant d'amortisseur de choc 1 entre la masse oscillante 2 et la platine 8 que comporte le mouvement 3. Il résulte de cette disposition que la face 23 de la masse 2 qui est opposée à celle à laquelle est fixée la plaque 4 se trouve située directement sur le fond que présente la pièce d'horlogerie. , It is preferable to have the plate 4 serving as a shock absorber 1 between the rotor 2 and the plate 8 that has the movement 3. It follows from this arrangement that the face 23 of the weight 2 which is opposite to that which is the fixed plate 4 is located directly on the bottom that has the timepiece. Cette face 23 peut être munie d'un décor qui peut être rendu visible si le fond est une glace saphir par exemple. This face 23 may be provided with a decoration which can be rendered visible if the background is a sapphire crystal for example. Si la masse 2 n'est pas munie de moyens de butée pour limiter son ébat axial lors d'un choc, sa face décorée peut entrer en contact avec le fond et être ainsi endommagée. If the mass 2 is not provided with stop means for limiting the axial clearance upon impact, its decorated face may come into contact with the bottom and thus be damaged.
  • Un mode de réalisation possible pour limiter l'ébat en question est montré en One possible embodiment to limit the shake in question is shown in figures 3 et 4 Figures 3 and 4 qui sont des représentations simplifiées d'un principe pris en exemple. which are simplified representations of a principle taken as an example. La The figure 3 Figure 3 est une vue en plan de ce mode de réalisation et la is a plan view of this embodiment and the figure 4 Figure 4 une coupe à échelle agrandie selon la ligne IV - IV de la an enlarged section along the line IV - IV of figure 3 Figure 3 . . Dans ces figures, les moyens de butée consistent en une gorge 15 pratiquée dans la masse oscillante 2. Dans cette gorge 15 pénètre avec jeu une languette 16 de retenue qui peut terminer un pont de limitation 17 comme cela sera apparent sur la In these figures, the abutment means consist of a groove 15 formed in the rotor 2. In this groove 15 penetrates with clearance a tab retainer 16 which may terminate a limiting bridge 17 as will be apparent on figure 6 Figure 6 . . Les jeux seront calculés de façon à ce que la masse 2 ne vienne jamais toucher en cas de choc ni le fond, ni la platine de la pièce d'horlogerie. The games will be calculated so that the mass 2 never comes to touch on impact or the background or the platinum timepiece.
  • La The figure 5 Figure 5 est une vue en plan et la is a plan view and figure 6 Figure 6 une coupe à échelle agrandie selon la ligne VI - VI de la an enlarged section along line VI - VI of figure 5 Figure 5 d'un mode d'exécution pratique et particulier de la présente invention. a practical embodiment and particularly of the present invention.

The face 23 of the mass 2 may be provided with a decoration and appear through a transparent background. La The figure 7 Figure 7 est une vue en perspective éclatée du mécanisme objet de la présente invention et fait mieux comprendre les vue et coupe des is an exploded perspective view of the mechanism object of the present invention and is better understand the view and cutting figures 5 et 6 Figures 5 and 6 respectives. respectively.
  • Dans cette exécution particulière, la plaque 4 jouant le rôle d'amortisseur de choc 1 et définie plus haut présente la forme d'un secteur 9 sensiblement semi-circulaire. In this particular embodiment, the plate 4 acting as a shock absorber 1 and defined above in the form of a sector 9 substantially semicircular. Ce secteur 9 est fixé dans sa zone périphérique 10 à la masse oscillante 2 et dans sa zone centrale 11 au tube 5. La zone intermédiaire 12 située entre lesdites zones périphérique et centrale présente un milieu élastique susceptible de fléchir en cas de chocs portés sur la masse oscillante 2. The sector 9 is fixed in its peripheral zone 10 to the rotor 2 and in its central region 11 to the tube 5. The intermediate zone 12 between said peripheral and central zones has an elastic medium capable of bending in case of shocks worn on the 2 oscillating weight.
  • Une manière de rendre élastique la zone intermédiaire 12 du secteur 9 est d'y pourvoir des vides laissant subsister des bras reliant la zone centrale 11 à la zone périphérique 10 comme cela est bien explicité dans l'exposé d'invention One way to make the elastic intermediate region 12 of the sector 9 is of providing for leaving empty arms connecting the central zone 11 to the peripheral zone 10 as is well explained in the statement of invention CH 279 001 CH 279 001 cité plus haut. cited above. Si l'épaisseur du secteur 9 est suffisamment mince les bras présenteront la flexibilité voulue. If the thickness of 9 sector is sufficiently thin arms present the flexibility.
  • La The figure 8 Figure 8 est une vue en plan d'un mode d'exécution du secteur 9 présenté en perspective sur la is a plan view of a sector of the embodiment 9 shown in perspective in figure 7 Figure 7 . . On voit que la zone intermédiaire 12 comporte trois bras élastiques 18, 19 et 20 prenant naissance dans la zone périphérique 10 et se dirigeant vers la zone centrale 11 qui entoure l'axe de rotation 7 de la masse oscillante 2. It is seen that the intermediate zone 12 comprises three elastic arms 18, 19 and 20 begin in the peripheral zone 10 and moving towards the central zone 11 surrounding the rotational axis 7 of the rotor 2.
  • La The figure 9 Figure 9 est une vue en plan d'un autre mode d'exécution du secteur 9 constituant l'amortisseur de choc de la présente invention. is a plan view of another embodiment of sector 9 constituting the shock absorber of the present invention. Ici la zone intermédiaire 12 ne comporte que deux bras élastiques 13 et 14 reliant les zones périphérique 10 et centrale 11 du secteur 9. Here the intermediate region 12 includes only two spring arms 13 and 14 connecting the central 10 and peripheral zones 11 of 9 sector.
  • Pour terminer cette description, on reviendra sur la coupe de la To complete this description, it will return to the cup of figure 6 Figure 6 à laquelle on associera la perspective de la to which associate the perspective of the figure 7 Figure 7 . .
  • L'arbre 6 et son axe 7 autour duquel tourne la masse oscillante 2 est solidaire de la platine 8 du mouvement 3 esquissé en The axis 6 and its shaft 7 around which the rotor 2 is secured to the plate 8 of the movement 3 outlined in figure 5 Figure 5 . . La masse 2 est supportée par le secteur semi-circulaire 9. La zone périphérique 10 de ce secteur 9 est fixée à la masse 2 au moyen de vis 21. La zone centrale 11 de ce même secteur 9 est fixée au tube 5 au moyen de vis 22. Le tube 5 tourne librement autour de l'arbre 6. Un roulement à billes 25 est disposé entre l'arbre 6 et le tube 5. La couronne 26 du roulement 25 est chassée à l'intérieur du tube 5 et la partie centrale 27 du même roulement 25 est ajusté sur l'arbre 6 et y est maintenue axialement entre un épaulement 28 pratiqué sur l'arbre 6 et une clavette 29. Le tube 5 entraîne une roue 30 qui est fixée au tube 5 par les mêmes vis 22 utilisées pour fixer le secteur 9 audit tube 5. La The mass 2 is supported by the semicircular sector 9. The peripheral zone 10 of the sector 9 is fixed to the ground 2 by means of screws 21. The central zone 11 of the same sector 9 is fixed to the tube 5 by means of screw 22. the tube 5 rotates freely about the shaft 6. A ball bearing 25 is disposed between the shaft 6 and the tube 5. the ring 26 of the bearing 25 is forced inside the tube 5 and the part center 27 of the bearing 25 is fitted on the shaft 6 and is held there axially between a shoulder 28 made on the shaft 6 and a wedge 29. the tube 5 drives a wheel 30 which is fixed to the tube 5 by the same screws 22 used to secure the tube 9 to said area 5. the figure 6 Figure 6 montre que le secteur 9 est pris en sandwich entre le tube 5 et la roue 30. La même figure montre encore que la roue 30 entraîne un premier mobile intermédiaire 31 débutant une chaîne aboutissant à un rochet à remonter. shows that the sector 9 is sandwiched between the tube 5 and the wheel 30. The same figure also shows that the wheel 30 drives a first intermediate wheel 31, starting a chain leading to a ratchet up. L'arbre 32 de ce premier mobile est pivoté entre la platine 8 et un pont 17 qui est prolongé par la languette 16 limitant l'ébat axial de la masse 2, cette languette étant introduite dans la gorge 15 dont il a été question plus haut. The shaft 32 of the first mobile is pivoted between the plate 8 and a bridge 17 which is extended by the tongue 16 limiting the axial clearance of the mass 2, said tongue being inserted into the groove 15 which has been discussed above .
