Description

Domaine de l'inventionField of the invention

L'invention concerne un mouvement d'horlogerie comportant une tige de mise à l'heure mobile longitudinalement et en rotation selon un axe de tige dans une platine, ledit mouvement comportant au moins un mécanisme de commande d'affichage lequel comporte au moins un compteur dont un axe pivote autour d'un axe de pivotement, ledit axe étant sécant avec ledit axe de tige.The invention relates to a watch movement comprising a setting rod movable longitudinally and in rotation along a rod axis in a plate, said movement comprising at least one display control mechanism which comprises at least one counter an axis pivots about a pivot axis, said axis being secant with said shaft axis.

L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement.The invention also relates to a timepiece comprising at least one such movement.

L'invention concerne le domaine des mécanismes d'affichage d'horlogerie, et tout particulièrement celui des chronographes.The invention relates to the field of clock display mechanisms, and particularly that of chronographs.

Arrière-plan de l'inventionBackground of the invention

Sur les pièces d'horlogerie à affichage multiple, l'implantation d'une pluralité de compteurs, dédiés chacun à l'affichage d'une grandeur particulière, pose souvent problème, dans certaines zones déjà très encombrées du mouvement, en particulier au voisinage de la tige de commande de mise à l'heure, et, dans certains cas, de commande de remontage ou/et d'ajustement d'autres grandeurs, quantième, jour, mois, fuseau, ou autre.On multi-display timepieces, the implantation of a plurality of counters, each dedicated to the display of a particular quantity, is often problematic, in certain areas already very congested with movement, particularly in the vicinity of the control rod time setting, and in some cases, winding control and / or adjustment of other quantities, calendar, day, month, time zone, or other.

Il est alors connu d'implanter l'axe de pivotement d'un tel compteur sur la platine, lié au rouage de finissage. Cette disposition présente l'inconvénient d'un éloignement du rouage du mécanisme de commande d'affichage, dont le compteur est un des périphériques d'affichage, rouage qui est traditionnellement disposé au niveau d'un pont de rouage, et éloigné de la zone du rouage de finissage.It is then known to implant the pivot axis of such a counter on the plate, linked to the work train. This arrangement has the disadvantage of a distance from the gear of the display control mechanism, whose counter is a display device, which is traditionally arranged at a gearset, and away from the area the finishing gear.

Le document JP 62 251690 A au nom de SEIKO EPSON Corp. décrit un mécanisme d'affichage permettant de corriger uniquement un affichage d'une pièce d'horlogerie principale tout en maintenant un autre affichage, par une opération unique en réglant le couple de freinage d'une bascule de commande à une valeur supérieure à celle du couple de glissement d'un mécanisme coulissant. Lors de la traction de la tige de remontoir, un mécanisme de commutation transmet la rotation de la tige, par un pignon coulant, à une roue des heures pour corriger l'affichage principal. Une bascule principale associée au pignon coulant comporte un ergot de coopération avec un mobile sautant. La bascule principale a pour effet d'empêcher la transmission d'une rotation de la roue des heures principale, provoquée par la correction principale, à une roue des heures subordonnée, dont le réglage est possible par un poussoir annexe coopérant avec une bascule secondaire comportant un crochet agencé pour son attelage avec un crochet complémentaire de la bascule principale.The document JP 62 251690 A on behalf of SEIKO EPSON Corp. discloses a display mechanism for correcting only one display of a main timepiece while maintaining another display, by a single operation by adjusting the braking torque of a control lever to a value greater than that of the sliding torque of a sliding mechanism. When pulling the winding stem, a switching mechanism transmits the rotation of the rod, by a sliding pinion, to an hour wheel to correct the main display. A main rocker associated with the sliding pinion comprises a cooperation lug with a jumping mobile. The main rocker has the effect of preventing the transmission of a rotation of the main hours wheel, caused by the main correction, to a subordinate hour wheel, the adjustment of which is possible by an auxiliary pushbutton cooperating with a secondary rocker comprising a hook arranged for its coupling with a complementary hook of the main rocker.

Résumé de l'inventionSummary of the invention

L'invention se propose d'améliorer l'implantation d'un tel compteur, en le logeant au plus près du mécanisme de commande de mise à l'heure, de façon à pouvoir couvrir un diamètre d'affichage le plus grand possible, tout en améliorant la qualité des pivotements par rapport à l'art antérieur.The invention proposes to improve the implementation of such a counter, by housing it as close to the time setting control mechanism, so as to cover the largest display diameter possible, while improving the quality of pivoting compared to the prior art.

L'invention se propose, encore, de rendre le compteur proche de la tige, indépendant du rouage de finissage.The invention proposes, again, to make the counter close to the rod, independent of the work train.

A cet effet, l'invention concerne un mouvement d'horlogerie comportant une tige de mise à l'heure mobile longitudinalement et en rotation selon un axe de tige dans une platine, ledit mouvement comportant au moins un mécanisme de commande d'affichage lequel comporte au moins un compteur dont un axe pivote autour d'un axe de pivotement, ledit axe étant sécant avec ledit axe de tige, caractérisé en ce que ledit axe est agencé pour pivoter dans une première pierre dont une première portée externe est chassée dans ladite platine, et dont une deuxième portée externe est agencée pour guider en pivotement l'alésage d'une roue de renvoi de mise à l'heure commandable par ladite tige.For this purpose, the invention relates to a clockwork movement comprising a setting rod movable longitudinally and in rotation along a rod axis in a plate, said movement comprising at least one display control mechanism which comprises at least one counter having an axis pivoting about a pivot axis, said axis being secant with said rod axis, characterized in that said axis is arranged to pivot in a first stone, a first outer bearing is driven in said platen , and a second outer bearing surface of which is arranged to pivotally guide the bore of a time setting wheel which can be controlled by said rod.

L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement, caractérisé en ce que ladite pièce est une montre-bracelet.The invention also relates to a timepiece comprising at least one such movement, characterized in that said piece is a wristwatch.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne un mouvement 100 d'horlogerie.The invention relates to a watch movement 100.

Ce mouvement 100 comporte une tige de mise à l'heure 2 mobile longitudinalement et en rotation selon un axe de tige T dans une platine 3.This movement 100 comprises a setting rod 2 movable longitudinally and in rotation along a rod axis T in a plate 3.

Le mouvement 100 comporte au moins un mécanisme de commande d'affichage 200, lequel comporte au moins un compteur 1 dont un axe 4 pivote autour d'un axe de pivotement D.The movement 100 comprises at least one display control mechanism 200, which comprises at least one counter 1 whose axis 4 pivots about a pivot axis D.

Cet axe 4 est sécant avec l'axe de tige T.This axis 4 is secant with the axis of rod T.

Selon l'invention, cet axe 4 pivote dans une première pierre 6. Cette première pierre 6 est montée dans l'axe T de la tige 2, elle comporte une première portée 61 externe qui est chassée dans la platine 3, et une deuxième portée 62 externe qui guide en pivotement l'alésage 71 d'une roue de renvoi de mise à l'heure 7 commandable par la tige 2. De préférence, tel que visible sur la figure 2, la première portée 61 externe et la deuxième portée 62 externe sont juxtaposées, et forment ensemble une surface de révolution autour de l'axe de pivotement D. De préférence, la première portée 61 et la deuxième portée 62 externe sont cylindriques et de même diamètre.According to the invention, this axis 4 pivots in a first stone 6. This first stone 6 is mounted in the axis T of the rod 2, it comprises a first outer surface 61 which is driven into the plate 3, and a second scope 62 which guides the bore 71 pivotally of a time setting wheel 7 controllable by the rod 2. Preferably, as visible on the figure 2 , the first outer surface 61 and the second outer surface 62 are juxtaposed, and together form a surface of revolution about the pivot axis D. Preferably, the first surface 61 and the second outer surface 62 are cylindrical and of the same diameter .

Dans une réalisation préférée, la platine 3 comporte, selon l'axe de pivotement D, un alésage 31 dans lequel est chassée la première portée 61. La platine 3 comporte classiquement, selon l'axe de tige T, un premier alésage avant 32 de guidage d'une première portée avant 22 de la tige 2 et un deuxième alésage arrière 33 de guidage d'une deuxième portée arrière 23 de la tige 2.In a preferred embodiment, the plate 3 comprises, along the axis of pivoting D, a bore 31 in which is driven the first bearing 61. The plate 3 conventionally comprises, along the rod axis T, a first bore 32 before guiding a first front bearing surface 22 of the rod 2 and a second rear guide bore 33 of a second rear bearing surface 23 of the rod 2.

De façon préférée, la pierre 6 est tout entière d'un seul côté du premier alésage avant 32, du côté d'une première extrémité 46 de l'arbre 4, tel que visible sur la figure 2. C'est à proximité de cette première extrémité 46 que l'axe 4 est guidé, par un bobineau 41 qu'il comporte, dans un alésage 64 de la première pierre 6. De préférence, ce bobineau 41 est guidé dans une surface intérieure qui est au même niveau que la première portée 61 externe, le bobineau est ainsi fermement maintenu, sans être en porte-à-faux par rapport à la platine 3. La pierre 6 comporte une face d'extrémité 63 qui est en retrait du premier alésage avant 62, ou tangente avec lui. Cette disposition permet notamment, lors du montage, de passer une broche dans l'alésage 62 avant le montage de la tige, de façon à limiter la course de chassage de la première pierre 6 dans l'alésage 31 de la platine 3, ce qui assure automatiquement la cote de longueur souhaitée pour chacune des portées 61 et 62.Preferably, the stone 6 is entirely on one side of the first front bore 32, on the side of a first end 46 of the shaft 4, as visible on the figure 2 . It is near this first end 46 that the axis 4 is guided, by a bobbin 41 that it comprises, in a bore 64 of the first stone 6. Preferably, this bobbin 41 is guided in an inner surface which is the same level as the first outer scope 61, the coil is thus firmly maintained, without being cantilevered with respect to the plate 3. The stone 6 has an end face 63 which is set back from the first bore before 62, or tangent with it. This arrangement makes it possible, during assembly, to pass a spindle into the bore 62 before mounting the rod, so as to limit the hunting stroke of the first stone 6 in the bore 31 of the plate 3, which automatically provides the desired length dimension for each of the staves 61 and 62.

En somme, la première pierre 6 a une triple fonction :

  • la première portée 61 de son diamètre extérieur est utilisée pour la tenue de la première pierre 6 dans la platine 3 ;
  • la deuxième portée 62 de son diamètre extérieur est utilisée pour le pivotement du renvoi de mise à l'heure 7 ;
  • le diamètre intérieur 64 est utilisé pour le pivotement du bobineau 41 de l'axe 4.
In sum, the first stone 6 has a triple function:
  • the first span 61 of its outer diameter is used for the holding of the first stone 6 in the plate 3;
  • the second span 62 of its outer diameter is used for the pivoting of the time-setting reference 7;
  • the inside diameter 64 is used for the pivoting of the bobbin 41 of the axis 4.

Dans une réalisation particulière, la platine 3 comporte au moins un filet 34 agencé pour coopérer, à frottement minimal, avec une portée d'appui 74 de la roue de renvoi de mise à l'heure 7, pour la limitation d'ébat de cette roue de renvoi de mise à l'heure 7 par rapport à la platine 3.In a particular embodiment, the plate 3 comprises at least one thread 34 arranged to cooperate, with minimum friction, with a bearing surface 74 of the time setting wheel 7, for the fretting limitation of this time setting return wheel 7 with respect to the plate 3.

Le mouvement 100 comporte de préférence un pont de rouage 9, qui comporte une deuxième pierre 91 dans laquelle pivote un pivot 42 que comporte l'axe 4 à une deuxième extrémité 47 opposée à la première extrémité 46.The movement 100 preferably comprises a gear wheel 9, which comprises a second stone 91 in which pivots a pivot 42 that includes the axis 4 at a second end 47 opposite the first end 46.

Le mécanisme de commande d'affichage 200 comporte un rouage engrenant avec une denture 44 que comporte une roue de compteur 43 solidaire en pivotement de l'axe 4, et qui est située à proximité immédiate du pont de rouage 9. Cette disposition est un avantage, car, dans un cas particulier où le mécanisme de commande d'affichage 200 est un mécanisme de chronographe, il est ainsi possible de motoriser l'axe 4 du compteur à la hauteur de ce pont de rouage 9, de façon équivalente aux autres compteurs, ce qui n'était pas le cas dans l'art antérieur où l'implantation d'un compteur dans l'alignement de la tige imposait un déport d'altitude par rapport aux autres compteurs.The display control mechanism 200 comprises a gear meshing with a toothing 44 that comprises a counter wheel 43 pivotally integral with the axis 4, and which is located in the immediate vicinity of the gear wheel bridge 9. This arrangement is an advantage because, in a particular case where the display control mechanism 200 is a chronograph mechanism, it is thus possible to motorize the axis 4 of the counter at the height of this wheel bridge 9, in a manner equivalent to the other counters , which was not the case in the prior art where the implementation of a counter in the alignment of the rod imposed an altitude offset compared to other meters.

Tel que visible sur la figure 2, la roue de renvoi de mise à l'heure 7 comporte une denture 72 agencée pour engrener, dans certaines positions longitudinales de la tige 2, avec une denture frontale 81 que comporte un pignon coulant 8 assujetti en pivotement à la tige 2 autour du axe de tige T et mobile longitudinalement selon l'axe de tige T, par un agencement classique de carré mâle 21 de la tige 2 coopérant avec un carré femelle 82 du pignon coulant 8.As visible on the figure 2 , the setting wheel of time setting 7 comprises a toothing 72 arranged to mesh, in certain longitudinal positions of the rod 2, with a front toothing 81 that includes a sliding pinion 8 pivotally secured to the rod 2 about the axis T-rod and mobile longitudinally along the axis of rod T, by a conventional arrangement of male square 21 of the rod 2 cooperating with a female square 82 of the sliding pinion 8.

De préférence, l'axe 4 porte, à sa première extrémité 46 distale au-delà de la deuxième portée 62 de la première pierre 6, une portée d'aiguille 45 pour la réception d'une aiguille 5 d'affichage du compteur 1.Preferably, the axis 4 carries, at its first end 46 distal beyond the second bearing 62 of the first stone 6, a needle bearing 45 for receiving a display needle 5 of the counter 1.

L'invention trouve une application avantageuse, mais non limitative, quand le mécanisme de commande d'affichage 200 est un mécanisme de chronographe.The invention finds an advantageous, but not limiting, application when the display control mechanism 200 is a chronograph mechanism.

L'invention concerne encore une pièce d'horlogerie 300, comportant au moins un tel mouvement 100, et en particulier une pièce 300 qui est une montre-bracelet.The invention also relates to a timepiece 300, comprising at least one such movement 100, and in particular a piece 300 which is a wristwatch.

En somme, l'invention permet d'avoir une aiguille 5 de compteur 1 sur l'axe T de la tige de mise à l'heure 2, tout particulièrement dans la position à 3h de celle-ci par rapport à la montre 300.In short, the invention makes it possible to have a counter needle 1 on the T-axis of the time-setting rod 2, particularly in the 3 o'clock position of the latter relative to the watch 300.

L'invention permet de motoriser l'axe du compteur à la hauteur du pont de rouage 9, comme les autres compteurs du mécanisme de commande d'affichage 200.The invention makes it possible to motorize the axis of the counter at the height of the gear train 9, like the other counters of the display control mechanism 200.

L'axe 4 du compteur 1 est ainsi rendu indépendant de ces autres compteurs.The axis 4 of the counter 1 is thus made independent of these other counters.

Le renvoi de mise à l'heure 7 bénéficie d'un pivotement de qualité sur la deuxième portée 62 de la première pierre 6, contrairement à de nombreuses réalisations usuelles où le coussinet est souvent une goutte usinée directement dans la platine 3, et est sujette à l'usure.The time setting return 7 has a quality pivoting on the second range 62 of the first stone 6, unlike many usual embodiments where the pad is often a drop machined directly in the plate 3, and is subject to to wear.

L'engrènement du pignon coulant 8 sur le renvoi de mise à l'heure 7 se fait directement, et de façon très compacte, le mouvement 100 ainsi réalisé est de faible hauteur.The meshing of the sliding pinion 8 on the time setting return 7 is directly, and very compactly, the movement 100 thus produced is of low height.

L'invention permet, encore, l'utilisation d'un axe 4 standard, qui pivote sur la platine 3 et sur le pont de rouage 9.The invention allows, again, the use of a standard axis 4, which pivots on the plate 3 and on the gearset 9.
