Description

La présente invention se rapporte à un mouvement d'horlogerie comprenant un bâti portant un barillet contenant un ressort moteur, un rouage de finissage, un mécanisme d'échappement et un balancier-spiral.The present invention relates to a watch movement comprising a frame carrying a barrel containing a mainspring, a finishing gear, an escapement mechanism and a sprung balance.

Un mouvement d'horlogerie est susceptible de recevoir diverses « complications », nom donné par les horlogers à tous les mécanismes additionnels destinés à indiquer des intervalles de temps autres que les heures les minutes et les secondes. Ces mécanismes sont souvent constitués par des modules additionnels qui sont rapportés sur le mouvement d'horlogerie et sont reliés à lui par l'un de ses mobiles, du rouage de finissage ou de celui de minuterie.A watch movement is likely to receive various "complications", a name given by watchmakers to all additional mechanisms intended to indicate time intervals other than hours, minutes and seconds. These mechanisms are often constituted by additional modules that are reported on the watch movement and are connected to it by one of its mobiles, the gear train or the timer.

Le document CH376061 divulgue un mouvement permettant de placer au choix la roue de seconde au centre ou excentrée. Dans certains cas, la présence d'une aiguille des secondes et donc d'une roue des secondes au centre peut constituer une entrave au mécanisme additionnel dont on désire munir le mouvement d'horlogerie. Dans d'autres cas, la roue des secondes au centre du mouvement d'horlogerie n'est pas gênante et est souhaitée. L'inconvénient vient du fait qu'il est nécessaire d'avoir deux mouvements d'horlogerie différents pour répondre à ces exigences. Deux mouvements d'horlogerie différents impliquent deux lignes de fabrication distinctes.The document CH376061 discloses a movement for placing the choice of the second wheel in the center or eccentric. In some cases, the presence of a second hand and therefore a second wheel in the center may be an obstacle to the additional mechanism that is to be provided with the watch movement. In other cases, the seconds wheel at the center of the watch movement is not annoying and is desired. The disadvantage comes from the fact that it is necessary to have two different clock movements to meet these requirements. Two different watch movements involve two separate production lines.

Le but de la présente invention est de permettre, à partir d'un même mouvement d'horlogerie, d'avoir une roue des secondes au centre ou une roue des secondes décentrée.The object of the present invention is to allow, from the same clockwork, to have a second wheel in the center or an off-center seconds wheel.

A cet effet, la présente invention a pour objet un mouvement d'horlogerie selon la revendication 1.For this purpose, the subject of the present invention is a watch movement according to claim 1.

L'avantage d'un tel mouvement est de permettre une rationalisation plus poussée de la fabrication à partir d'un seul et même mouvement, alors qu'aujourd'hui, il est nécessaire de changer de mouvement suivant le type de complication dont on désire équiper la pièce d'horlogerie. Il est évident que le fait de permettre d'équiper un même mouvement du plus grand nombre possible de complications simplifie sensiblement la planification de la fabrication.The advantage of such a movement is to allow a further rationalization of manufacturing from a single movement, while today, it is necessary to change the movement depending on the type of complication which one wishes to equip the timepiece. It is obvious that allowing the same number of complications to be equipped with the same number of complications substantially simplifies the planning of manufacture.

Les dessins annexés illustrent, schématiquement et à titre d'exemple, une forme d'exécution du mouvement d'horlogerie objet de la présente invention.

  • La figure 1 est une vue en plan du mouvement d'horlogerie dans sa version aiguille des secondes au centre;
  • la figure 2 est une vue en plan de ce même mouvement d'horlogerie dans sa version aiguille des secondes décentrée;
  • la figure 3 est une vue en plan partielle du mouvement d'horlogerie selon la figure 1 et représentant l'ensemble de l'échappement et du système réglant.
The accompanying drawings illustrate, schematically and by way of example, an embodiment of the watch movement object of the present invention.
  • The figure 1 is a plan view of the watchmaking movement in its second hand central seconds;
  • the figure 2 is a plan view of this same clockwork movement in its off-center second-hand version;
  • the figure 3 is a partial plan view of the watch movement according to the figure 1 and representing the entire exhaust and regulating system.

La figure 1 illustre un mouvement d'horlogerie de montre comprenant essentiellement un ressort moteur logé dans un barillet 1 dont la denture engrène avec le pignon de la roue des minutes 2 qui ne se situe pas au centre du mouvement. Cette roue des minutes engrène avec le pignon de la roue de moyenne 3 qui engrène avec le pignon de la roue des secondes 4 dont l'axe coïncide avec l'axe central du mouvement d'horlogerie. Cette roue des secondes engrène avec le pignon de la roue d'échappement 5.The figure 1 illustrates a clock watch movement essentially comprising a motor spring housed in a barrel 1 whose teeth meshes with the pinion of the minute wheel 2 which is not in the center of the movement. This minute wheel meshes with the pinion of the wheel of average 3 which meshes with the pinion of the seconds wheel 4 whose axis coincides with the central axis of the watch movement. This second wheel meshes with the pinion of the escape wheel 5.

Etant donné que la roue des minutes 2 ne se situe pas au centre du mouvement d'horlogerie, la roue de moyenne 3 porte un second pignon (non représenté) du côté du mouvement tourné vers le cadran et engrène avec une roue des minutes située au centre du mouvement et qui porte la chaussée (non représentée). Ces éléments sont connus de l'homme de l'art et ne sont pas nécessaires à la compréhension de la présente invention.Since the minute wheel 2 is not at the center of the watch movement, the average wheel 3 carries a second gear (not shown) on the movement side facing the dial and meshes with a minute wheel located at center of the movement and which carries the pavement (not shown). These elements are known to those skilled in the art and are not necessary for the understanding of the present invention.

Le rouage de finissage qui vient d'être décrit est porté, comme habituellement entre des paliers solidaires d'une platine 6 et des paliers solidaires de ponts fixés sur la platine 6. Ces ponts ont été enlevés pour permettre de voir le rouage de finissage.The finishing gear that has just been described is worn, as usually between solidarity bearings a plate 6 and integral bearings bridges fixed on the plate 6. These bridges have been removed to allow to see the finishing train.

Comme illustré en particulier par la figure 3, l'ensemble de l'échappement et du système réglant comprenant la roue d'échappement 5, une ancre 7 et un balancier spiral 8 est disposé sur un bâti auxiliaire 9. Un pont d'échappement 10 fixé au bâti auxiliaire 9 par deux vis 11 comporte un premier palier 12 pour le pivotement de l'extrémité supérieure de l'arbre de la roue d'échappement 5. Un pont d'ancre 13 est fixé par deux vis 14, dont seule l'une est visible sur la figure 1, tandis que l'autre est visible sur la figure 2. Ce pont d'ancre comporte un palier 15 pour le pivotement de l'extrémité supérieure de l'arbre de l'ancre 7. Enfin un pont de balancier 16 est fixé par deux vis 17 au bâti auxiliaire 9. Ce pont de balancier 16 comporte un palier 18 pour le pivotement de l'extrémité supérieure de l'arbre du balancier-spiral 8. Le bâti auxiliaire 9 est fixé à la platine 6 par deux vis 19 et est positionné par des pieds (non représentés) à l'instar des ponts.As illustrated in particular by the figure 3 , the exhaust system and the regulating system comprising the escape wheel 5, an anchor 7 and a balance spring 8 is disposed on an auxiliary frame 9. An exhaust bridge 10 attached to the auxiliary frame 9 by two screws 11 comprises a first bearing 12 for pivoting the upper end of the shaft of the escape wheel 5. An anchor bridge 13 is fixed by two screws 14, of which only one is visible on the figure 1 , while the other is visible on the figure 2 . This anchor bridge comprises a bearing 15 for pivoting the upper end of the anchor shaft 7. Finally a balance bridge 16 is fixed by two screws 17 to the auxiliary frame 9. This balance bridge 16 comprises a bearing 18 for pivoting the upper end of the balance spring shaft 8. The auxiliary frame 9 is fixed to the plate 6 by two screws 19 and is positioned by feet (not shown) like the bridges.

Comme on peut le constater sur la figure 3, le pont d'échappement 10 comporte un second palier 20 symétrique au premier palier 12 par rapport à un axe de symétrie reliant les axes du balancier-spiral 8 à celui de la roue de moyenne 3. Sur les figures 1 et 3, ce second palier 20 est inutilisé. La platine auxiliaire 9 comporte une ouverture 25 constituant le siège du premier palier 12 pour l'arbre de la roue d'échappement 5.As can be seen from the figure 3 , the exhaust bridge 10 comprises a second bearing 20 symmetrical to the first bearing 12 with respect to an axis of symmetry connecting the axes of the sprung balance 8 to that of the wheel of average 3. On figures 1 and 3 this second bearing 20 is unused. The auxiliary plate 9 has an opening 25 constituting the seat of the first bearing 12 for the shaft of the escape wheel 5.

Si l'on se réfère maintenant à la figure 2, on constate que la roue d'échappement 5 est maintenant pivotée dans le second palier 20 du pont d'échappement 10. Le pignon de la roue d'échappement 5 engrène avec la roue des secondes 4 qui est alors décentrée par rapport au centre du mouvement d'horlogerie. Son pignon engrène avec la roue de moyenne 3 qui reste à la même place que dans la figure 1.If we now refer to the figure 2 , it is found that the escape wheel 5 is now pivoted in the second bearing 20 of the exhaust bridge 10. The pinion of the escape wheel 5 meshes with the seconds wheel 4 which is then off-center with respect to the center of the movement watchmaking. Its gear meshes with the wheel of average 3 which remains in the same place as in the figure 1 .

On voit sur la figure 1 des ouvertures 26 et 23 ménagées respectivement dans le bâti auxiliaire 9 et dans la platine 6, constituant les sièges pour recevoir les paliers inférieur des arbres de pivotement respectifs de l'ancre d'échappement 7 et de la roue des secondes 4, dans la version à roue des secondes décentrée illustrée par la figure 2.We see on the figure 1 openings 26 and 23 formed respectively in the auxiliary frame 9 and in the plate 6, constituting the seats for receiving the lower bearings of the respective pivot shafts of the escape anchor 7 and the seconds wheel 4, in the version second wheel off-center illustrated by the figure 2 .

On voit par ailleurs sur la figure 2 des ouvertures 24 et 25 ménagées dans le bâti auxiliaire 9, constituant respectivement les sièges pour recevoir les paliers inférieurs des arbres de pivotement respectifs de l'ancre 7 et de la roue d'échappement 5, dans la version à roue des secondes centrée illustrée par la figure 1.We also see on the figure 2 openings 24 and 25 formed in the auxiliary frame 9, respectively constituting the seats for receiving the lower bearings of the respective pivot shafts of the anchor 7 and the escape wheel 5, in the second wheel-centered version illustrated by the figure 1 .

Le pont d'ancre 13 est déplacé angulairement autour de l'axe de pivotement du balancier-spiral 8 et le bâti auxiliaire 9 comporte des moyens pour le positionnement et la fixation du pont d'ancre 13 par les vis 14 dans les deux positions, celle de la figure 1 comme celle de la figure 2.The anchor bridge 13 is angularly displaced about the pivot axis of the balance spring 8 and the auxiliary frame 9 comprises means for positioning and fixing the anchor bridge 13 by the screws 14 in the two positions, that of figure 1 like that of the figure 2 .

Comme on peut le constater, les figures 1 et 2 correspondent respectivement aux versions du mouvement d'horlogerie à roue des secondes au centre, donc à aiguille des secondes au centre et à aiguille des secondes décentrée, à partir d'un mouvement d'horlogerie comportant les mêmes composants. En effet, il n'existe aucune pièce différente ni aucune pièce en plus ou en moins entre les deux versions de ce mouvement, y compris en ce qui concerne le bâti auxiliaire 9, seule la place de l'ancre 7, de la roue d'échappement 5 et de la roue des secondes 4 change. Par contre ni la structure, ni le nombre des pièces ne change.As can be seen, the figures 1 and 2 correspond respectively to the versions of the second wheel clock movement in the center, and therefore to second hand in the center and second hand off-center, from a watch movement comprising the same components. Indeed, there is no different part or part more or less between the two versions of this movement, including with regard to the auxiliary frame 9, only the place of the anchor 7, the wheel d Exhaust 5 and the seconds wheel 4 changes. On the other hand, neither the structure nor the number of pieces changes.

En outre, le bâti auxiliaire 9 permet d'effectuer le montage sur ce bâti auxiliaire 9 selon la version pour roue des secondes au centre, ou selon la version pour roue des secondes décentrées. Il suffit alors de monter la version de ce module pré-assemblé avec la roue d'échappement 5 pivotée dans les paliers ou sièges de paliers 12, 25 et l'ancre 7 dans les paliers ou sièges de paliers 15, 24 sur une platine 6 avec roue des secondes au centre ou de monter la version de ce module pré-assemblé avec la roue d'échappement 5 pivotée dans les paliers ou sièges de paliers 20, 22 et l'ancre 7 dans les paliers ou sièges de paliers 15, 26 sur une platine 6 avec roue des secondes 4 décentrées.In addition, the auxiliary frame 9 allows mounting on the auxiliary frame 9 according to the version for the second wheel in the center, or according to the wheel version of the off-center seconds. It is then sufficient to mount the version of this pre-assembled module with the escapement wheel 5 pivoted in the bearings or bearing seats 12, 25 and the anchor 7 in the bearings or bearing seats 15, 24 on a plate 6 with center seconds wheel or mounting the version of this pre-assembled module with the escapement wheel 5 rotated in the bearings or bearing seats 20, 22 and the anchor 7 in the bearings or bearing seats 15, 26 on a plate 6 with 4 offset seconds wheel.

L'identité totale de tous les composants des deux versions du mouvement d'horlogerie constitue également un avantage pour le service après-vente, du fait que toutes les pièces sont utilisables indifféremment dans les deux versions, ce qui simplifie leur remplacement en supprimant les risques d'erreurs.The total identity of all the components of the two versions of the watch movement is also an advantage for the after-sales service, since all the parts can be used in both versions, which simplifies their replacement by eliminating the risks. errors.
