Description

La présente invention concerne une montre à remontage automatique comprenant une indication de la réserve de marche.The present invention relates to a self-winding watch comprising an indication of the power reserve.

Dans une montre à remontage automatique, les mouvements du porteur sont transmis au ressort de barillet par l'intermédiaire d'une masse oscillante et d'un rouage de démultiplication. Cette masse peut être fixée au centre du mouvement ou éventuellement décentrée. Généralement, le mécanisme de remontage automatique est placé au-dessus du mouvement, côté ponts. Toutefois, il arrive également fréquemment que la masse oscillante soit disposée au-dessous du mouvement Le rouage du mécanisme de remontage automatique se compose d'éléments dentés qui permettent de transmettre la force depuis la masse oscillante jusqu'au rochet et d'armer le ressort de barillet. Ce rouage de mécanisme de remontage automatique se compose généralement des éléments suivants: pignon de la masse oscillante, mobiles intermédiaires redresseurs de sens, mobiles de réduction et rochet. Le rouage du mécanisme de remontage automatique se compose en général d'une partie train de renvoi et d'une partie rouage démultiplicatif aussi appelé rouage réducteur. C'est ce dernier qui a pour but de réduire la vitesse initiale de la masse oscillante et d'accroître la force destinée à l'armage du ressort de barillet.In a self-winding watch, the movements of the wearer are transmitted to the mainspring by means of an oscillating weight and a reduction gear train. This mass can be fixed at the center of the movement or possibly off-center. Generally, the automatic winding mechanism is placed above the movement, side bridges. However, it is also frequently the case that the oscillating mass is arranged below the movement. The gearing of the automatic winding mechanism consists of toothed elements which make it possible to transmit the force from the oscillating mass to the ratchet and to arm the spring. barrel. This automatic winding mechanism gear generally consists of the following elements: oscillating weight gearwheel, intermediate moving direction straighteners, reduction mobiles and ratchet. The gear of the automatic winding mechanism generally consists of a gear train part and a gear train gear also called gear reducer. It is the latter which aims to reduce the initial speed of the oscillating weight and increase the force for winding the mainspring.

Certains constructeurs munissent les montres à remontage automatique d'un dispositif indicateur de réserve de marche, c'est-à-dire un dispositif permettant au porteur de connaître à n'importe quel moment le nombre d'heures durant lesquelles la montre fonctionnera encore sans être remontée. La réserve de marche est alors indiquée soit par un disque portant des chiffres dont l'un est visible à travers un guichet, soit au moyen d'une aiguille se déplaçant au-dessus d'une graduation supplémentaire.Some manufacturers provide self-winding watches with a power-reserve indicator device, that is to say a device allowing the wearer to know at any time the number of hours during which the watch will still function without to be reassembled. The power reserve is then indicated either by a disc bearing figures, one of which is visible through a window, or by means of a needle moving above an additional graduation.

La combinaison d'un mécanisme de remontage automatique avec une indication de la réserve de marche est plutôt réservée à des montres de prix, habituellement appelées montres à complications. De telles montres peuvent comprendre, outre le mécanisme d'affichage de réserve de marche, un mécanisme chronographe, un mécanisme de quantième, un mécanisme d'indication des phases de lune ou autres, de sorte que la place disponible sur le cadran de telles montres pour l'indication de la réserve de marche est réduite.The combination of an automatic winding mechanism with an indication of the power reserve is rather reserved for price watches, usually called complicated watches. Such watches may include, in addition to the power-reserve display mechanism, a chronograph mechanism, a date mechanism, a mechanism for indicating moon phases or the like, so that the space available on the dial of such watches for the indication of the power reserve is reduced.

La présente invention a pour but de pallier cet inconvénient en agençant le mécanisme indicateur de réserve de marche en un endroit de la montre où l'on dispose davantage de place.The present invention aims to overcome this disadvantage by arranging the power reserve indicator mechanism in a place of the watch where there is more room.

A cet effet, la présente invention concerne une montre à remontage automatique comprenant une masse oscillante dont les mouvements sont transmis à un ressort de barillet de la montre, cette montre comprenant également un dispositif indicateur de réserve de marche comprenant des moyens d'affichage de la réserve de marche, caractérisée en ce que les moyens d'affichage de la réserve de marche sont montés sur la masse oscillante.For this purpose, the present invention relates to a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, this watch also comprising a power reserve indicator device comprising means for displaying the power reserve, characterized in that the display means of the power reserve are mounted on the oscillating weight.

Grâce à ces caractéristiques, la présente invention procure une pièce d'horlogerie à remontage automatique comprenant un mécanisme indicateur de réserve de marche dont les moyens d'affichage de la réserve de marche sont portés par la masse oscillante. En procédant de la sorte, on libère de la place sur le cadran de la montre, ce qui permet d'afficher des informations horaires ou non liées au temps de manière plus lisible ou de rajouter des indications supplémentaires. Par ailleurs, comme les masses oscillantes sont souvent de grandes dimensions, cela permet d'afficher l'information relative à la réserve de marche de manière plus lisible.Thanks to these features, the present invention provides a timepiece with automatic winding comprising a power reserve indicator mechanism whose power reserve display means are carried by the oscillating weight. By proceeding in this way, there is free space on the dial of the watch, which allows to display time or non-time-related information in a more legible manner or to add additional information. Moreover, since the oscillating masses are often large, this makes it possible to display the information relating to the power reserve more legibly.

Selon une autre caractéristique de l'invention, la montre à remontage automatique comprend un mécanisme différentiel à deux entrées et une sortie, une première entrée étant constituée par une roue de renvoi reliée cinématiquement au dispositif indicateur de réserve de marche, tandis que la deuxième entrée est constituée par un mécanisme qui compense la rotation des moyens d'affichage du dispositif indicateur de réserve de marche induite par la rotation de la masse oscillante, la sortie du mécanisme différentiel étant constituée par les moyens d'affichage de la réserve de marche.According to another characteristic of the invention, the self-winding watch comprises a differential mechanism with two inputs and an output, a first input being constituted by a return wheel connected kinematically to the power reserve indicator device, while the second input is constituted by a mechanism that compensates for the rotation of the display means of the power reserve indicator device induced by the rotation of the oscillating mass, the output of the differential mechanism being constituted by the display means of the power reserve.

Grâce à ces autres caractéristiques, la position relative des moyens d'affichage de la réserve de marche par rapport à la masse oscillante reste inchangée lorsque cette dernière tourne, sauf bien entendu en ce qui concerne les déplacements des moyens d'affichage inhérents au chargement/déchargement du ressort de barillet.Thanks to these other characteristics, the relative position of the display means of the power reserve with respect to the oscillating weight remains unchanged when the latter rotates, except of course with regard to the displacements of the display means inherent to the loading / unloading of the mainspring.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suite d'un mode de réalisation de la montre selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement en liaison avec le dessin annexé sur lequel :

  • la figure 1 est une vue de dessus d'une masse oscillante portant des moyens indicateurs de la réserve de marche conformément à l'invention, et
  • la figure 2 est une vue en coupe du dispositif indicateur de réserve de marche selon l'invention.
Other features and advantages of the present invention will emerge more clearly from the detailed description which follows from an embodiment of the watch according to the invention, this example being given for purely illustrative and nonlimiting purposes only in connection with the drawing. annexed in which:
  • FIG. 1 is a view from above of an oscillating weight carrying indicator means of the power reserve according to the invention, and
  • Figure 2 is a sectional view of the power reserve indicator device according to the invention.

La présente invention procède de l'idée générale inventive qui consiste à loger les moyens d'affichage d'un dispositif indicateur de réserve de marche dans la masse oscillante d'une montre à remontage automatique. Ce faisant, on libère de la place sur le cadran de la montre pour afficher plus d'informations ou des informations de manière plus lisible sur ce cadran, tandis qu'en raison des dimensions de la masse oscillante il est également plus aisé de lire l'indication relative à la réserve de marche.The present invention proceeds from the general inventive idea of housing the display means of a power reserve indicator device in the oscillating weight of a self-winding watch. In doing so, we free up space on the dial of the watch to display more information or information in a more legible way on this dial, while because of the dimensions of the oscillating mass it is also easier to read the indication relative to the power reserve.

La présente invention va être décrite en liaison avec des moyens d'affichage de l'indication de réserve de marche à aiguille. Il va de soi que cet exemple est donné à titre purement illustratif et non limitatif seulement, et que l'invention peut s'appliquer de manière analogue à une indication de la réserve de marche au moyen d'un disque. On notera également que l'invention s'applique indifféremment à une masse oscillante située au-dessous ou au-dessus du mouvement de la montreThe present invention will be described in connection with means for displaying the power reserve indication. It goes without saying that this example is given purely by way of illustration and not limitation, and that the invention can be applied analogously to an indication of the power reserve by means of a disk. It will also be noted that the invention applies equally to an oscillating mass situated below or above the movement of the watch

Le dispositif indicateur de réserve de marche, désigné dans son ensemble par la référence numérique générale 1, comprend classiquement un rouage qui relie cinématiquement un ressort de barillet de la montre (non représenté) à des moyens d'affichage de la réserve de marche tels qu'une aiguille 2. Seul un renvoi de sortie 4 du dispositif indicateur de réserve de marche 1 est représenté au dessin. Ce renvoi de sortie 4 tourne lentement en sens horaire ou anti-horaire selon que le ressort de barillet s'arme ou se désarme. Pour les besoins de la présente description, on supposera que ce renvoi de sortie 4 est sensiblement immobile et constitue l'une des entrées d'un mécanisme différentiel 6.The power reserve indicator device, generally designated by the general numerical reference 1, conventionally comprises a train which kinematically links a mainspring of the watch (not shown) to means for displaying the power reserve such that A needle 2. Only an output gear 4 of the power reserve indicator device 1 is shown in the drawing. This output reference 4 rotates slowly clockwise or counterclockwise as the barrel spring is armed or disarmed. For the purposes of the present description, it will be assumed that this output reference 4 is substantially stationary and constitutes one of the inputs of a differential mechanism 6.

En tournant autour d'un axe X-X, la masse oscillante 8 entraîne avec elle une roue de différentiel 10 montée libre via un palier 12 autour d'un axe de différentiel 14 qui porte, à son extrémité libre, l'aiguille 2 indicatrice de la réserve de marche. La roue de différentiel 10 porte un mobile de satellite 16 formé d'une roue de satellite 18 elle-même chassée sur un pignon de satellite 20. L'ensemble roue de satellite 18 et pignon de satellite 20 est libre en rotation autour d'une goupille 22 chassée dans la roue de différentiel 10. Ainsi, lorsque la roue de différentiel 10 tourne, elle roule sur le renvoi de sortie 4 du dispositif 1 indicateur de réserve de marche et entraîne en rotation la roue de satellite 18. Cette dernière engrène à son tour avec un pignon de différentiel 24 fixé sur l'axe de différentiel 14. En admettant que le rapport d'engrenage pour l'entraînement de l'axe de différentiel soit égal à 1, l'aiguille 2 indicatrice de la réserve de marche va être entraînée en même temps que la masse oscillante 8 tourne. Il faut donc compenser ce déplacement de façon que l'aiguille 2 reste immobile par rapport à la masse oscillante 8 sauf, bien entendu, pour ce qui est de l'armage et du désarmage du ressort de barillet.By rotating about an axis XX, the oscillating mass 8 carries with it a differential wheel 10 freely mounted via a bearing 12 around a differential axis 14 which carries, at its free end, the needle 2 indicative of the power reserve. The differential wheel 10 carries a satellite mobile 16 formed of a satellite wheel 18 itself driven on a satellite gear 20. The satellite wheel assembly 18 and satellite gear 20 is free to rotate around a wheel. pin 22 driven into the differential wheel 10. Thus, when the differential wheel 10 rotates, it rolls on the output gear 4 of the device 1 power reserve indicator and rotates the satellite wheel 18. The latter meshes with in turn with a differential gear 24 fixed on the differential axis 14. Assuming that the gear ratio for the drive of the differential axis is equal to 1, the needle 2 indicative of the power reserve will be driven at the same time as the oscillating mass 8 rotates. It is necessary to compensate for this displacement so that the needle 2 remains immobile with respect to the oscillating mass 8 except, of course, with regard to the winding and disarming of the mainspring.

Pour compenser le déplacement de l'aiguille 2 indicatrice de la réserve de marche inhérent au pivotement de la masse oscillante 8 il est prévu un mobile d'entrée de différentiel désigné dans son ensemble par la référence numérique générale 26 et qui se compose d'une roue 28 et d'un pignon 30. Le pignon 30 est solidaire de la roue 28 et l'ensemble ainsi formé est libre en rotation autour de l'axe de différentiel 14. Par suite, lorsque la masse oscillante 8 tourne, elle entraîne en rotation la roue 28 d'entrée de différentiel qui roule sur la denture d'une couronne d'entrée 32 fixée sur les ponts 34 du mouvement. En tournant, la roue 28 d'entrée de différentiel entraîne en rotation le pignon 30 d'entrée de différentiel qui engrène avec le pignon de satellite 20. Celui-ci entraîne en rotation la roue de satellite 18 qui engrène avec le pignon de différentiel 24 pour finalement entraîner en rotation l'axe de différentiel 14 et donc l'aiguille 2 indicatrice de la réserve de marche. En admettant que le rapport d'engrenage pour la compensation du déplacement de l'aiguille indicatrice de la réserve de marche est égal à -1, dans ce cas les deux rapports d'entrée du renvoi de sortie 4 et de la couronne 32 s'annulent et l'aiguille 2 indicatrice de la réserve de marche reste immobile.In order to compensate for the displacement of the pointer 2 indicative of the power reserve inherent in the pivoting of the oscillating mass 8, a differential input gear designated as a whole by the general reference numeral 26 and which consists of a wheel 28 and a pinion 30. The pinion 30 is integral with the wheel 28 and the assembly thus formed is free to rotate about the differential axis 14. Consequently, when the oscillating mass 8 rotates, it drives in rotation the differential input wheel 28 which rolls on the toothing of an input ring 32 fixed on the bridges 34 of the movement. By turning, the differential input wheel 28 rotates the differential input gear 30 which meshes with the planet pinion 20. This causes the planet wheel 18 which rotates with the differential gear 24 to rotate. to finally rotate the differential axis 14 and thus the needle 2 indicative of the power reserve. Assuming that the gear ratio for the compensation of the displacement of the indicator needle of the power reserve is equal to -1, in this case the two input ratios of the output gear 4 and the gear 32 cancel and the indicator needle 2 of the power reserve remains stationary.

Lors de l'armage ou du désarmage du ressort de barillet de la montre, le renvoi de sortie 4 tourne en sens horaire, respectivement anti-horaire et provoque la rotation de l'aiguille 2 indicatrice de réserve de marche sur la masse oscillante 8.When winding or disarming the mainspring of the watch, the output gear 4 rotates clockwise, respectively anti-clockwise and causes the rotation of the needle 2 power reserve indicator on the oscillating weight 8.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. En particulier, il peut être envisagé d'intercaler des roues de renvoi intermédiaires entre le renvoi de sortie 4 et la roue de différentiel 10 d'une part, et entre la couronne d'entrée 32 et la roue 28 d'entrée de différentiel d'autre part, pour peu que les rapports d'engrenage soient égaux et de signes opposés. On notera enfin que l'axe de différentiel 14 est porté par un pont de limitation 36. En liaison avec les figures 1 et 2, on voit que l'aiguille 2 indicatrice de la réserve de marche est noyée dans une creusure 38 pratiquée dans la masse oscillante 8.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, it may be envisaged to interpose intermediate return wheels between the output gear 4 and the differential wheel 10 on the one hand, and between the input ring 32 and the differential input wheel 28 on the other hand, provided that the gear ratios are equal and of opposite signs. Finally, it will be noted that the differential axis 14 is carried by a limiting bridge 36. In connection with FIGS. 1 and 2, it can be seen that the pointer 2 indicative of the power reserve is embedded in a recess 38 made in FIG. oscillating weight 8.
