Abstract

The device has locking levers (52, 52') maintaining jumpers (50, 50') out of correction phases of date indication, respectively. The levers move aside from a locking position of the jumpers by an activation unit (54) for liberating the jumpers in correction phases of the date indication, respectively. Each lever is locked between corresponding jumper and the activation unit out of the correction periods of the date indication. The lever is provided with diametrically opposite arms (53a, 53b) that allow the lever to be supported against the jumper and a toothed wheel.

Description

La présente invention concerne un dispositif d'aide au maintien en position indexée d'un disque indicateur de quantième pour pièce d'horlogerie.The present invention relates to a device for maintaining the indexed position of a date indicator disc for a timepiece.

Un exemple de réalisation d'un mécanisme indicateur de quantième est représenté en perspective à la figure 1 annexée à la présente demande de brevet. Désigné dans son ensemble par la référence numérique générale 1, un tel mécanisme est destiné à être monté dans la platine d'une montre non illustrée, typiquement une montre-bracelet destinée à afficher le jour du mois. Le mécanisme de quantième 1 comprend un anneau de quantième supérieur 2 et un anneau de quantième inférieur 3. L'anneau de quantième supérieur 2 est superposé à l'anneau de quantième inférieur 3. L'anneau de quantième supérieur 2 présente seize secteurs régulièrement répartis sur sa circonférence. Les seize secteurs comportent sur la face supérieure de l'anneau 2 des marquages successifs allant de « 17 » à « 31 » ainsi qu'une fenêtre 21 qui, dans l'exemple représenté, correspond à une ouverture traversante ménagée dans l'anneau de quantième supérieur 2. L'anneau de quantième inférieur 3 présente également seize secteurs régulièrement répartis sur sa circonférence. Les seize secteurs comportent sur la face supérieure de l'anneau 3 des marquages successifs allant de « 1 » à « 16 ». La montre présentera typiquement un guichet au travers duquel les marquages présents sur les anneaux de quantième inférieur 3 et supérieur 2 pourront être vus.An exemplary embodiment of a date indicator mechanism is shown in perspective at the figure 1 attached to this patent application. Designated as a whole by the general numerical reference 1, such a mechanism is intended to be mounted in the plate of a non-illustrated watch, typically a wristwatch intended to display the day of the month. The date mechanism 1 comprises an upper date ring 2 and a lower date ring 3. The upper date ring 2 is superimposed on the lower date ring 3. The upper date ring 2 has sixteen regularly distributed sectors. on its circumference. The sixteen sectors comprise on the upper face of the ring 2 successive markings ranging from "17" to "31" and a window 21 which, in the example shown, corresponds to a through opening formed in the ring of upper calendar 2. The lower date ring 3 also has sixteen sectors evenly distributed around its circumference. The sixteen sectors have on the upper face of the ring 3 successive markings ranging from "1" to "16". The watch will typically have a window through which the markings on the lower and upper date rings 3 and 2 can be seen.

Les figures 2 et 3 représentent plus précisément des détails constitutifs des anneaux de quantième inférieur 3 et supérieur 2. Des dents 22 font saillie radialement vers l'intérieur de l'anneau de quantième supérieur 2 depuis un rebord périphérique intérieur 23 dudit anneau supérieur 2. De façon similaire, des dents 32 font saillie radialement vers l'intérieur de l'anneau de quantième inférieur 3 depuis un rebord intérieur 33 de celui-ci. Les dents 22 et 32 sont régulièrement espacées le long des rebords périphériques intérieurs 23 et 33 des anneaux de quantième 2 et 3 respectifs. Chaque dent 22 est associée à un marquage 24 ou à la fenêtre 21 de l'anneau de quantième supérieur 2. De même, chaque dent 32 est associée à un marquage 34 de l'anneau de quantième inférieur 3.The Figures 2 and 3 more precisely represent the constituent details of the lower and upper calendar rings 2. Teeth 22 project radially inwardly of the upper date ring 2 from an inner peripheral rim 23 of said upper ring 2. Similarly, teeth 32 protrude radially inwardly of the lower date ring 3 from an inner rim 33 thereof. The teeth 22 and 32 are regularly spaced along the inner peripheral rims 23 and 33 of the respective date rings 2 and 3. Each tooth 22 is associated with a marking 24 or the window 21 of the upper date ring 2. Similarly, each tooth 32 is associated with a marking 34 of the lower date ring 3.

Le mécanisme indicateur de quantième 1 comprend de plus une roue de commande 4 pour entraîner les anneaux de quantième supérieur 2 et inférieur 3 qui effectue un tour complet en 31 jours en étant entraînée via un pignon 61 chassé sur la roue des heures et des engrenages 62 et 63 qui ne seront pas décrits davantage ici.The date indicator mechanism 1 further comprises a control wheel 4 for driving the top and bottom 2 and lower date rings 3 which performs a complete revolution in 31 days being driven via a pinion 61 driven on the hour wheel and gears 62 and 63 which will not be described further here.

La figure 4 annexée à la présente demande de brevet est une vue de détail en perspective de la roue de commande 4. Comme il ressort de cette figure, la roue de commande 4 présente des premier et second étages de dentures 41 et 42 superposés. Chacun des étages 41 et 42 présente sur son pourtour une portion munie de dents adjacentes successives et une portion dépourvue de dent. Dans la portion munie de dents de chacun des premier et second étages de dentures 41 et 42, les dents sont régulièrement espacées d'un angle de 2π/31.The figure 4 attached to the present patent application is a detail view in perspective of the control wheel 4. As apparent from this figure, the control wheel 4 has first and second stages of teeth 41 and 42 superimposed. Each of the stages 41 and 42 has on its periphery a portion provided with successive adjacent teeth and a portion without teeth. In the portion provided with teeth of each of the first and second gear stages 41 and 42, the teeth are regularly spaced by an angle of 2π / 31.

Comme visible sur la figure 4, sur chacune des dents des étages de dentures 41 et 42 a été reportée une référence numérique indiquant lequel des secteurs des anneaux de quantième inférieur 3 et supérieur 2 est commandé par cette dent. Ainsi, le premier étage de denture 41 comprend des dents qui vont commander les secteurs « 17 » à « 31 » et la fenêtre 21 de l'anneau de quantième supérieur 2. La portion dépourvue de dent du premier étage de denture 41 s'étend donc entre la dent qui commande le secteur correspondant à la fenêtre 21 et la dent qui commande le secteur « 17 ». Le second étage de denture 42 comprend quant à lui des dents qui commandent les secteurs « 1 » à « 16 ». La portion dépourvue de dent du second étage de denture 42 s'étend donc entre la dent qui commande le secteur « 16 » et la dent qui commande le secteur « 1 ». La portion pourvue de dents d'un étage est placée à l'aplomb de la portion dépourvue de dent de l'autre étage. Ainsi, les dents du premier étage de denture 41 commandant les marquages « 17 » à « 31 » de l'anneau supérieur 2 sont disposées à l'aplomb de la portion du second étage de denture 42 dépourvue de dent. La portion dépourvue de dent du premier étage de denture 41 est placée à l'aplomb des dents du second étage de denture 42 commandant les marquages « 2 » à « 16 » de l'anneau de quantième inférieur 3. Par exception, la dent du premier étage de denture 41 qui commande le secteur « 1 » de l'anneau de quantième inférieur 3 est disposée à l'aplomb de la dent du second étage de denture 42 qui commande le secteur correspondant à la fenêtre 21 de l'anneau de quantième supérieur 2.As visible on the figure 4 , on each of the teeth of the toothed stages 41 and 42 has been reported a numerical reference indicating which of the sectors of the lower and upper date ring 3 and 2 is controlled by this tooth. Thus, the first gear stage 41 includes teeth that will control the sectors "17" to "31" and the window 21 of the upper date ring 2. The toothless portion of the first gear stage 41 therefore extends between the tooth that controls the sector corresponding to the window 21 and the tooth that controls the sector "17". The second gear stage 42 comprises teeth that control the sectors "1" to "16". The toothless portion of the second gear stage 42 thus extends between the tooth that controls the sector "16" and the tooth that controls the sector "1". The portion provided with teeth of a stage is placed in line with the toothless portion of the other stage. Thus, the teeth of the first gear stage 41 controlling the markings "17" to "31" of the upper ring 2 are disposed vertically above the portion of the second toothless stage 42 without teeth. The toothless portion of the first gear stage 41 is placed in alignment with the teeth of the second gear stage 42 controlling the markings "2" to "16" of the lower date ring 3. By exception, the tooth of the first tooth stage 41 which controls the sector "1" of the lower date ring 3 is disposed vertically above the tooth of the second tooth stage 42 which controls the sector corresponding to the window 21 of the date ring. superior 2.

Les premier et deuxième étages de dentures 41 et 42 sont couplés en rotation, de sorte qu'une simple rotation d'un tour de la roue de commande 4 permet d'entraîner l'un ou l'autre des deux anneaux de quantième supérieur 2 ou inférieur 3. Les premier et second étages de dentures 41 et 42 sont agencés pour entraîner respectivement l'anneau de quantième supérieur 2 et l'anneau de quantième inférieur 3 par leurs portions munies de dents. Des mobiles multiplicateurs 11 et 13 permettent de réaliser une liaison cinématique entre les premier et second étages de dentures 41 et 42 et les anneaux de quantième supérieur 2 et inférieur 3 respectivement. Les mobiles multiplicateurs 11 et 13 permettent de garantir que la rotation quotidienne de la roue de commande 4 implique l'avance d'un pas d'un anneau de quantième d'un quantième au quantième suivant.The first and second stages of teeth 41 and 42 are coupled in rotation, so that a simple rotation of one turn of the control wheel 4 makes it possible to drive one or the other of the two upper date rings 2 or lower 3. The first and second stages of teeth 41 and 42 are arranged to respectively drive the upper date ring 2 and the lower date ring 3 by their portions provided with teeth. Mobile multipliers 11 and 13 make it possible to achieve a kinematic connection between the first and second gear stages 41 and 42 and the top and bottom 2 and lower date rings 3, respectively. The multiplier mobiles 11 and 13 make it possible to guarantee that the daily rotation of the control wheel 4 involves the advance of a step of a date ring from a date to the next date.

La figure 5 annexée à la présente demande de brevet est une vue de côté du mécanisme de correction de l'indication de quantième. Comme illustré sur cette figure, le premier étage de denture 41 est relié cinématiquement à l'anneau de quantième supérieur 2 par l'intermédiaire du premier engrenage multiplicateur 11, du troisième engrenage multiplicateur 13 et de l'engrenage supérieur d'un train d'engrenages correcteur 9. L'engrenage multiplicateur 11 comprend un pignon 112 entraîné par la partie dentée du premier étage de denture 41. L'engrenage multiplicateur 11 comprend par ailleurs une roue 111 fixée sur le pignon 112. L'engrenage multiplicateur 13 comprend quant à lui un pignon 131 entraîné par la roue 111. L'engrenage multiplicateur 13 comprend de plus une roue 132 fixée sur le pignon 131 et entraînant l'engrenage supérieur du train d'engrenages correcteur 9.The figure 5 attached to this patent application is a side view of the correction mechanism of the date indication. As illustrated in this figure, the first gear stage 41 is kinematically connected to the upper date ring 2 via the first multiplier gear 11, the third gear 13 and the upper gear of a gear train. correction gear 9. The multiplier gear 11 comprises a pinion 112 driven by the toothed portion of the first gear stage 41. The multiplier gear 11 further comprises a wheel 111 fixed to the gear 112. The multiplier gear 13 comprises as it a pinion 131 driven by the wheel 111. The multiplier gear 13 further comprises a wheel 132 fixed on the pinion 131 and driving the upper gear of the corrective gear train 9.

Durant la rotation de la roue de commande 4, le fonctionnement du mécanisme indicateur de quantième 1 est le suivant. On suppose que la fenêtre 21 et le marquage « 1 » sont initialement placés sous le guichet de la montre. Le premier quantième du mois est donc visible par le porteur de la montre. Lors du passage, commandé par la roue de commande 4, du premier quantième au second, puis du second au troisième et ainsi de suite jusqu'au quantième « 16 » :

  • la partie dépourvue de dents du premier étage de denture 41 est en regard du premier mobile 11. L'anneau de quantième supérieur 2 n'est donc pas entraîné et la fenêtre 21 reste immobile, placée sous le guichet de la montre ;
  • les dents du second étage de denture 42 qui commandent le déplacement des marquages « 2 » à « 16 » vont successivement être en prise avec le deuxième engrenage multiplicateur 12 et donc entraîner l'anneau de quantième inférieur 3 par ses dents 32. Ainsi, les quantièmes « 2 » à « 16 » seront successivement visibles dans le guichet de la montre à travers la fenêtre 21.
During the rotation of the control wheel 4, the operation of the date indicator mechanism 1 is as follows. It is assumed that the window 21 and the marking "1" are initially placed under the window of the watch. The first day of the month is visible by the wearer of the watch. During the passage, controlled by the control wheel 4, from the first date to the second, then from the second to the third and so on until the date "16":
  • the toothless portion of the first tooth stage 41 is opposite the first mobile 11. The upper date ring 2 is not driven and the window 21 remains stationary, placed under the window of the watch;
  • the teeth of the second gear stage 42 which control the displacement of the markings "2" to "16" will successively be engaged with the second multiplier gear 12 and thus drive the lower date ring 3 by its teeth 32. "2" to "16" will be successively visible in the window of the watch through the window 21.

Lors du passage, commandé par la roue 4, du quantième « 16 » marqué sur l'anneau de quantième inférieur 3 au quantième « 17 » marqué sur l'anneau de quantième supérieur 2 puis subséquemment du quantième « 17 » au quantième « 31 » :

  • la partie dépourvue de dents du second étage de denture 42 est en regard du deuxième engrenage multiplicateur 12. L'anneau de quantième inférieur 3 n'est donc pas entraîné et le quantième « 16 » reste immobile sous le guichet ;
  • les dents du premier étage de denture 41 qui commandent le déplacement des marquages « 17 » à « 31 » vont successivement être en prise avec le mobile 11, et donc entraîner l'anneau de quantième supérieur 2 par ses dents 22. Ainsi, les quantièmes « 17 » à « 31 » seront successivement affichés dans le guichet.
During the passage, controlled by the wheel 4, the date "16" marked on the lower date ring 3 to the date "17" marked on the upper date ring 2 and subsequently the date "17" to the date "31" :
  • the tooth-free portion of the second gear stage 42 is opposite the second multiplier gear 12. The lower date ring 3 is therefore not driven and the "16" calendar remains stationary under the window;
  • the teeth of the first stage of teeth 41 which control the movement of the markings "17" to "31" will successively be engaged with the mobile 11, and thus drive the upper date ring 2 by its teeth 22. Thus, the dates "17" to "31" will be successively displayed in the window.

Lors du passage du quantième « 31 » porté par l'anneau de quantième supérieur 2 au quantième « 1 » porté par l'anneau de quantième inférieur 3, la dent du premier étage de denture 41 qui commande le déplacement de la fenêtre 21 et qui est superposée à la dent du second étage de denture 42 qui commande le déplacement du marquage « 1 » sont simultanément en prise avec les mobiles 11 et 12 respectivement. L'anneau de quantième supérieur 2 pivote ainsi pour placer la fenêtre 21 sous le guichet, alors que l'anneau de quantième inférieur 3 pivote pour placer le marquage « 1 » sous le guichet.During the passage of the date "31" carried by the upper date ring 2 to the date "1" carried by the lower date ring 3, the tooth of the first gear stage 41 which controls the movement of the window 21 and which is superimposed on the tooth of the second gear stage 42 which controls the displacement of the marking "1" are simultaneously engaged with the mobiles 11 and 12 respectively. The upper date ring 2 thus pivots to place the window 21 under the aperture, while the lower date ring 3 pivots to place the marking "1" under the aperture.

On remarque à l'examen de la figure 1 que la position des anneaux de quantième supérieur 2 et inférieur 3 est indexée par un sautoir 50 maintenu par un ressort 51. Ces sautoirs 50 servent à maintenir les anneaux de quantième 2 et 3 en position et à éviter qu'ils ne tournent inopinément en dehors des périodes de correction de l'indication de quantième, par exemple sous l'effet d'un choc. Quand on cherche à obtenir un mécanisme de quantième dont la durée du saut soit aussi brève que possible, on doit prévoir un rapport de multiplication entre la roue de commande et l'anneau de quantième considéré aussi élevé que possible. Or, dans un tel cas, le couple disponible en sortie du train d'engrenages qui relie la roue de commande à l'anneau de quantième est faible, de sorte que la force exercée par le sautoir sur ledit anneau de quantième doit être aussi minime que possible pour pouvoir être vaincue lorsqu'on commande l'avance d'un pas de l'anneau de quantième. Mais si la force de retenue exercée par le sautoir sur l'anneau de quantième est faible, le risque est important de voir sauter l'anneau de quantième en cas de choc et d'avoir une indication erronée de la date.We notice in the examination of the figure 1 that the position of the upper and lower date rings 2 is indexed by a jumper 50 held by a spring 51. These jumpers 50 serve to hold the date rings 2 and 3 in position and to prevent them from spinning unexpectedly outside. periods of correction of the date indication, for example under the effect of a shock. When one seeks to obtain a date mechanism whose jump duration is as short as possible, one must provide a multiplication ratio between the control wheel and the date ring considered as high as possible. However, in such a case, the torque available at the output of the gear train which connects the control wheel to the date ring is small, so that the force exerted by the jumper on said date ring must also be minimal. as much as possible to be defeated when ordering the advance of one step of the date ring. But if the retaining force exerted by the jumper on the date ring is small, the risk is important to see the date ring jump in case of shock and have a wrong indication of the date.

Le document EP 1 962 152 décrit un dispositif d'aide au maintien en position d'un disque indicateur de quantième pour pièce d'horlogerie, la position du disque indicateur de quantième étant indexée par un sautoir. Ce dispositif comprend un organe de blocage qui, en dehors des périodes de correction de l'indication de quantième, maintient bloqué le sautoir, cet organe de blocage s'effaçant en phase de correction de l'indication de quantième pour libérer le sautoir.The document EP 1 962 152 discloses a device for assisting in the positioning of a date indicator disc for a timepiece, the position of the date indicator disc being indexed by a jumper. This device comprises a locking member which, apart from the periods of correction of the date indication, keeps the jumper blocked, this locking member fading during the correction phase of the date indication to release the jumper.

La présente invention a pour but de remédier à cet inconvénient ainsi qu'à d'autres encore en procurant un mécanisme indicateur de quantième présentant une résistance élevée aux chocs en dehors des périodes de correction de l'indication de quantième tout en n'opposant qu'un faible couple résistant durant les phases de correction de l'indication de quantième.The object of the present invention is to remedy this drawback as well as others by providing a date indicator mechanism having a high impact resistance outside the correction periods of the date indication while opposing only a low resisting torque during the correction phases of the date indication.

A cet effet, la présente invention concerne un dispositif d'aide au maintien en position d'un disque indicateur de quantième pour pièce d'horlogerie selon la revendication 1 annexée au présent brevet.For this purpose, the present invention relates to a support device for holding in position a date indicator disk for a timepiece according to claim 1 attached to this patent.

La présente invention concerne un mécanisme indicateur de quantième dont le disque de quantième est maintenu bloqué en dehors des phases de correction de l'indication de quantième et est libéré et juste maintenu indexé par un sautoir durant les phases de correction de l'indication de quantième. On est ainsi assuré que, durant le fonctionnement normal de la montre, le disque indicateur de quantième est fermement maintenu et ne risque pas de pivoter inopinément sous l'effet d'un choc par exemple. L'indication du quantième fournie par la montre équipée du mécanisme de quantième est donc toujours fiable. Par contre, au voisinage de minuit, lorsque l'indication de quantième doit changer, le disque de quantième n'est plus maintenu que par le sautoir qui oppose un faible couple résistant. Le couple disponible en sortie du train d'engrenages qui relie la roue de commande à l'anneau de quantième n'a donc pas besoin d'être élevé, de sorte que le rapport de multiplication entre ladite roue de commande et ledit anneau de quantième peut être grand. On obtient ainsi un mécanisme de quantième à saut plus rapide que celui d'un mécanisme traînant et qui se rapproche d'un mécanisme à saut instantané.The present invention relates to a date indicator mechanism whose date disk is kept locked outside the correction phases of the date indication and is released and just kept indexed by a jumper during the correction phases of the date indication. . It is thus ensured that, during the normal operation of the watch, the date indicator disc is firmly maintained and is not likely to rotate unexpectedly under the effect of a shock for example. The indication of the date provided by the watch equipped with the date mechanism is therefore always reliable. By cons, in the vicinity of midnight, when the date indication must change, the date disc is maintained only by the jumper which opposes a low resisting torque. The torque available at the output of the gear train that connects the control wheel to the date ring does not need to be high, so that the multiplication ratio between said control wheel and said date ring. can be big. This results in a date mechanism with a jump faster than that of a trailing mechanism and which is close to an instantaneous jump mechanism.

En phase de correction de l'indication de quantième, l'organe de verrouillage est écarté de sa position de blocage du sautoir par un organe d'activation qui est lui-même entraîné par un train d'engrenages qui relie cinématiquement une roue de commande au disque indicateur de quantième.In the correction phase of the date indication, the locking member is moved away from its locking position of the jumper by an activation member which is itself driven by a gear train which kinematically links a control wheel. to the date indicator disc.

Le sautoir n'est libéré de sa position de blocage qu'au moment même où le rouage de correction de l'indication de quantième se met en marche, ce qui se produit seulement une fois toutes les vingt-quatre heures pendant un faible laps de temps au voisinage de minuit ainsi que pendant les phases de correction manuelle de la date. Ainsi, pendant la majeure partie du temps, le disque de quantième est parfaitement immobilise et ne risque donc pas de sauter inopinément par exemple en cas de choc.The jumper is released from its blocking position only at the very moment when the date indicator correction wheel starts, which occurs only once every twenty-four hours for a short period of time. time around midnight as well as during manual correction of the date. Thus, during most of the time, the date disk is perfectly immobilized and therefore does not risk to jump unexpectedly for example in case of shock.

En dehors des phases de correction de l'indication de quantième, l'organe de verrouillage est bloqué entre le sautoir et l'organe d'activation.Outside the correction phases of the date indication, the locking member is blocked between the jumper and the activation member.

La présente invention procède de l'idée générale inventive qui consiste à concilier deux objectifs qui, de prime abord, paraissent antagonistes, à savoir procurer un mécanisme de quantième dont le disque indicateur de quantième soit à la fois fermement maintenu pour éviter qu'il ne pivote en cas de choc et fournisse une indication erronée du quantième, et oppose un couple résistant aussi faible que possible lors de sa correction pour pouvoir avancer d'un pas dans un laps de temps relativement faible grâce à un train d'engrenages présentant un rapport de multiplication élevé. Ce double objectif est atteint grâce à l'utilisation d'un organe qui bloque le disque indicateur de quantième en agissant sur son sautoir en dehors des périodes de correction de l'indication de quantième, cet organe étant écarté de sa position dans laquelle il bloque le disque indicateur de quantième durant les phases ou l'indication de quantième est corrigée.The present invention proceeds from the general inventive idea of reconciling two objectives which, at first glance, seem antagonistic, namely to provide a date mechanism whose date indicator disc is both firmly maintained to prevent it from rotates in the event of impact and provides an erroneous indication of the date, and opposes a resistant torque as low as possible during its correction to be able to advance a step in a relatively short period of time thanks to a gear train with a ratio of high multiplication. This dual purpose is achieved through the use of a member that blocks the date indicator disk by acting on its jumper outside periods of correction of the date indication, this body being removed from its position in which it blocks the date indicator disk during the phases or the date indication is corrected.

La présente invention va être décrite en liaison avec un mécanisme indicateur de quantième comprenant deux disques de quantième superposés. Il va de soi que la présente invention s'applique de manière identique à un mécanisme indicateur de quantième comprenant un seul disque de quantième qui serait divisé en 31 secteurs sur lesquels sont reportées les indications de quantième « 1 » à « 31 ».The present invention will be described in connection with a date indicator mechanism comprising two superposed date disks. It goes without saying that the present invention applies identically to a date indicator mechanism comprising a single date disc which would be divided into 31 sectors on which are reported the date indications "1" to "31".

Par souci de clarté, le mécanisme de blocage selon l'invention va être décrit en liaison avec l'anneau de quantième supérieur 2. On comprendra que le mécanisme de blocage associé à l'anneau de quantième inférieur 3 est identique à celui de l'anneau supérieur 2.For the sake of clarity, the locking mechanism according to the invention will be described in conjunction with the upper date ring 2. It will be understood that the locking mechanism associated with the lower date ring 3 is identical to that of the upper ring 2.

Comme déjà expliqué ci-dessus, les anneaux de quantième supérieur 2 et inférieur 3 sont reliés cinématiquement à la roue de commande 4 via un rouage de correction de l'indication de quantième comprenant les mobiles multiplicateurs 11 et 13, respectivement 12 et 14, ainsi que le mobile correcteur 9. Plus précisément, l'anneau de quantième supérieur 2 est entraîné par le premier étage de denture 41 de la roue de commande 4 via le premier mobile multiplicateur 11, le troisième mobile multiplicateur 13 et l'engrenage supérieur du mobile correcteur 9. L'engrenage multiplicateur 11 comprend le pignon 112 entraîné par la partie dentée du premier étage de denture 41. La roue 111 fixée coaxialement sur le pignon 112 entraîne le pignon 131 du troisième mobile multiplicateur 13. Enfin, la roue 132 fixée coaxialement sur le pignon 131 entraîne l'engrenage supérieur du mobile correcteur 9 qui a son tour entraîne l'anneau de quantième supérieur 2. Comme on peut le voir à l'examen de la figure 6, la position de l'anneau de quantième supérieur 2 est indexée par le sautoir 50 maintenu par un bras 51 a du ressort 51.As already explained above, the upper and lower 2 and lower date rings 3 are kinematically connected to the control wheel 4 via a date indication correction gear train comprising the multiplier mobiles 11 and 13, respectively 12 and 14, and that the corrector mobile 9. More specifically, the upper date ring 2 is driven by the first gear stage 41 of the control wheel 4 via the first mobile multiplier 11, the third mobile multiplier 13 and the upper gear of the mobile corrector 9. The multiplier gear 11 comprises the pinion 112 driven by the toothed portion of the first gear stage 41. The wheel 111 fixed coaxially on the pinion 112 drives the pinion 131 of the third multiplier 13. Finally, the wheel 132 fixed coaxially on the pinion 131 drives the upper gear of the corrector mobile 9 which in turn drives the upper date ring 2. As can be seen r at the examination of the figure 6 , the position of the upper date ring 2 is indexed by the jumper 50 held by an arm 51a of the spring 51.

On cherche à ce que le saut de l'indication de quantième d'un quantième donné au quantième suivant soit la plus rapide possible. Il faut donc que le rapport de multiplication entre la roue de commande 4 et l'anneau de quantième supérieur 2 via le premier mobile multiplicateur 11, le troisième mobile multiplicateur 13 et l'engrenage supérieur du mobile correcteur 9 soit le plus grand possible. Sous réserve que cette condition soit vérifiée et avec un angle entre deux pas de quantième de 22,5° qui est la valeur pour un mécanisme indicateur de quantième à deux disques, le changement de l'indication de quantième s'opère en environ 40 minutes. C'est habituellement la durée du saut d'un mécanisme indicateur de quantième de type semi-instantané à un seul disque, cette durée étant ramenée à 20 minutes pour un tel mécanisme indicateur de quantième à un seul disque grâce à la présente invention. On peut donc ranger le mécanisme de quantième selon l'invention dans la catégorie des quantièmes semi-instantanés, entre les quantièmes traînants et les quantièmes instantanés. Il est ainsi possible, en dimensionnant convenablement le rouage de correction de l'indication de quantième, d'obtenir un mécanisme de quantième dont le changement de date est plus rapide que par le passé mais, en contrepartie, le couple disponible en bout du rouage de correction au niveau de l'engrenage supérieur du mobile correcteur 9 est relativement faible. Il faut donc choisir un sautoir 50 exerçant sur l'anneau de quantième supérieur 2 une force de retenue suffisamment faible pour qu'elle puisse être vaincue par l'engrenage supérieur du mobile correcteur 9 en phase de correction de l'indication de quantième. On comprend immédiatement que, dans un tel cas, le maintien de l'anneau de quantième supérieur 2 assuré par le sautoir 50 n'est pas sans faille et que les risques de voir sauter l'anneau de quantième en cas de chocs sont importants.It is sought that the jump of the date indication of a given date to the next date is as fast as possible. It is therefore necessary that the multiplication ratio between the control wheel 4 and the upper date ring 2 via the first mobile multiplier 11, the third mobile multiplier 13 and the upper gear of the mobile corrector 9 be the largest possible. Provided that this condition is verified and with an angle between two date steps of 22.5 ° which is the value for a date indicator mechanism with two disks, the change of the date indication takes place in about 40 minutes. . This is usually the duration of the jumping of a single-disc semi-instantaneous date indicator mechanism, this time being reduced to 20 minutes for such a single disk date indicator mechanism by the present invention. We can store the date mechanism according to the invention in the category of semi-instantaneous dates, between trailing dates and instant calendars. It is thus possible, by suitably dimensioning the correction wheel of the date indication, to obtain a date mechanism whose date change is faster than in the past but, in return, the torque available at the end of the gear train correction at the upper gear of the corrective mobile 9 is relatively low. It is therefore necessary to choose a jumper 50 exerting on the upper date ring 2 a retaining force sufficiently low so that it can be overcome by the upper gear of the corrector mobile 9 in the correction phase of the date indication. It is immediately understood that, in such a case, the maintenance of the upper date ring 2 provided by the jumper 50 is not flawless and that the risks of seeing the date ring jump in case of shocks are important.

La présente invention s'est assigné pour objectif de résoudre ce problème en procurant un dispositif d'aide au maintien en position d'un anneau de quantième qui, en phase de fonctionnement normal de la montre, c'est-à-dire en dehors des périodes de correction de l'indication de quantième, garantit une excellente tenue aux chocs de l'anneau de quantième, tout en permettant une correction de l'indication de quantième avec un couple minimal. A cet effet, la présente invention enseigne d'adjoindre au mécanisme indicateur de quantième un organe de blocage qui, en dehors des périodes de correction de l'indication de quantième, maintient le sautoir bloqué et qui s'efface en phase de correction de l'indication de quantième pour libérer le sautoir. Dans l'exemple de réalisation représenté à la figure 6, cet organe de blocage, désigné dans son ensemble par la référence numérique générale 52, se présente sous la forme d'un levier dont l'axe de pivotement se confond avec son axe central de symétrie. Plus précisément, le levier de blocage 52 comprend deux bras 53a et 53b diamétralement opposés par lesquels il est en appui d'une part contre le sautoir 50 et d'autre part contre un organe d'activation 54 qui est lui-même activé par le rouage de correction de l'indication de quantième. Dans l'exemple représenté au dessin, cet organe d'activation 54 est formé par la roue 132 du troisième mobile multiplicateur 13. Bien entendu, cet exemple est donné à titre purement illustratif seulement et on pourrait envisager que le levier de blocage 52 soit en appui, directement ou via un élément intermédiaire, contre une autre roue du rouage de correction de l'indication de quantième.The present invention has set itself the objective of solving this problem by providing a device for helping to hold a date ring in position, which, in the normal operating phase of the watch, that is to say outside periods of correction of the date indication, ensures excellent shock resistance of the date ring, while allowing a correction of the date indication with a minimum torque. For this purpose, the present invention teaches adding to the date indicator mechanism a locking member which, outside the correction periods of the date indication, keeps the jumper blocked and disappears in the correction phase of the date indication to release the jumper. In the embodiment shown in figure 6 this locking member, generally designated by the general numerical reference 52, is in the form of a lever whose pivot axis merges with its central axis of symmetry. More specifically, the locking lever 52 comprises two arms 53a and 53b diametrically opposed by which it is supported on the one hand against the jumper 50 and on the other hand against an activation member 54 which is itself activated by the date correction wheel of the date indication. In the example shown in the drawing, this activation member 54 is formed by the wheel 132 of the third mobile multiplier 13. Of course, this example is given for illustrative purposes only and it could be envisaged that the locking lever 52 is in support, directly or via an intermediate element, against another wheel of the gear train of the date indication correction.

On voit que le bras 53b du levier de blocage 52 est maintenu appliqué contre les dents de la roue 132 par un bras 51 b du ressort 51 qui vient de matière avec le bras 51 a de ce dernier. Bien entendu, il serait tout à fait envisageable de prévoir deux ressorts distincts pour maintenir respectivement le sautoir 50 et le levier de blocage 52. On voit aussi que le sautoir 50 comprend une creusure 56 pour faciliter l'appui du bras 53a du levier de blocage 52.It can be seen that the arm 53b of the locking lever 52 is held pressed against the teeth of the wheel 132 by an arm 51b of the spring 51 which comes from the material with the arm 51a of the latter. Of course, it would be quite possible to provide two separate springs to respectively maintain the jumper 50 and the locking lever 52. It is also seen that the jumper 50 comprises a recess 56 to facilitate the support of the arm 53a of the locking lever 52.

On examine maintenant le fonctionnement du dispositif d'aide au maintien en position de l'anneau de quantième selon l'invention en liaison avec les figures 7A à 7F. En période de fonctionnement normal de la montre, c'est-à-dire en dehors des phases de correction de l'indication de quantième, le levier de blocage 52 est bloqué entre la roue 132 du troisième mobile multiplicateur 13 et le sautoir 50 qu'il maintient fermement appuyé contre l'anneau de quantième supérieur 2. Le mobile multiplicateur 13 et l'anneau de quantième supérieur 2 étant tous deux immobiles, il n'y a pas de risque que ledit anneau de quantième supérieur 2 bouge en cas de choc. Peu de temps avant minuit, on entre en phase de correction de l'indication de quantième et la roue de commande 4 commence à tourner (figure 7A). Le levier de blocage 52 étant maintenu contre la roue 132 du troisième mobile multiplicateur 13 par le bras 51 b du ressort 51, il n'y a pas de jeu entre ce levier 52 et cette roue 132. Par contre, il y a des jeux qui s'additionnent entre la roue 132 et l'engrenage supérieur du mobile correcteur 9 ainsi qu'entre l'engrenage supérieur du mobile correcteur 9 et l'anneau de quantième supérieur 2. En conséquence, quand la roue de commande 4 et donc la roue 132 du troisième mobile multiplicateur 13 commencent à tourner, ladite roue 132 va d'abord entraîner le levier de blocage 52 avant d'entraîner le mobile correcteur 9 et l'anneau de quantième 2. Ce faisant, la roue 132 va écarter le levier 52 de sa position de blocage à l'encontre de la force de rappel du bras 51 b du ressort 51 et ainsi libérer le sautoir 50 (figure 7B). Immédiatement après avoir écarté le levier 52 de sa position de blocage du sautoir 50, la roue 132 commence à faire tourner l'anneau de quantième 2 via l'engrenage supérieur du mobile correcteur 9. A partir de ce moment là (voir figure 7C). c'est le sautoir 50 qui devient l'organe de commande du levier de blocage 52. On observe en effet à ce stade que le bras 53a du levier de blocage 52 est sorti de la creusure 56 prévue sur le sautoir 50 et est en appui glissant contre un flanc droit 58 dudit sautoir 50 qui se trouve dans le prolongement de ladite creusure 56. Ainsi, lorsque l'anneau de quantième 2, entraîné par l'engrenage supérieur du mobile correcteur 9, se met à tourner, le sautoir 50 pivote à son tour pour passer de l'intervalle entre deux dents 22 de la denture intérieure de l'anneau de quantième 2 dans lequel il se trouve à l'intervalle suivant en passant par-dessus la dent 22 qui sépare ces deux intervalles. En pivotant, le sautoir 50 fait pivoter le levier de blocage 52 dans le sens horaire, c'est-à-dire dans le même sens que le sens dans lequel la roue 132 le fait pivoter, à l'encontre de la force de rappel du bras 51 b du ressort 51 qui tend à ramener ledit levier 52 dans sa positon de blocage du sautoir 50.We now examine the operation of the device for assisting in maintaining the position of the date ring according to the invention in connection with the Figures 7A to 7F . During normal operation of the watch, that is to say outside the correction phases of the date indication, the locking lever 52 is locked between the wheel 132 of the third mobile multiplier 13 and the jumper 50 which it keeps firmly pressed against the upper date ring 2. The mobile multiplier 13 and the upper date ring 2 being both immobile, there is no risk that said top date ring 2 move in case of shock. Shortly before midnight, the date indication correction phase is started and the control wheel 4 begins to rotate ( Figure 7A ). The locking lever 52 being held against the wheel 132 of the third mobile multiplier 13 by the arm 51 b of the spring 51, there is no clearance between the lever 52 and the wheel 132. However, there are games which add up between the wheel 132 and the upper gear of the corrector mobile 9 as well as between the upper gear of the corrector mobile 9 and the upper date ring 2. Consequently, when the control wheel 4 and therefore the wheel 132 of the third mobile multiplier 13 begin to rotate, said wheel 132 will first drive the locking lever 52 before driving the corrector mobile 9 and the date ring 2. In doing so, the wheel 132 will move the lever 52 of its locking position against the restoring force of the arm 51 b of the spring 51 and thus release the jumper 50 ( Figure 7B ). Immediately after having moved the lever 52 away from its blocking position of the jumper 50, the wheel 132 begins to turn the date ring 2 via the upper gear of the corrector mobile 9. From this moment on (see Figure 7C ). it is the jumper 50 which becomes the control member of the locking lever 52. It is indeed observed at this stage that the arm 53a of the locking lever 52 is out of the recess 56 provided on the jumper 50 and is in support sliding against a right side 58 of said jumper 50 which is in the extension of said recess 56. Thus, when the date ring 2, driven by the upper gear of the corrector mobile 9, begins to rotate, the jumper 50 rotates in turn to pass the interval between two teeth 22 of the internal toothing of the date ring 2 in which it is at the next interval by passing over the tooth 22 which separates these two intervals. By pivoting, the jumper 50 rotates the locking lever 52 clockwise, that is to say in the same direction as the direction in which the wheel 132 rotates it, against the return force arm 51 b of the spring 51 which tends to bring said lever 52 back to its locking position of the jumper 50.

A la figure 7D, le mécanisme de quantième selon l'invention est représenté dans la position qui précède immédiatement le passage de l'indication de quantième d'un quantième donné, en l'espèce le « 16 », au quantième suivant, ici le « 17 ». On voit sur cette figure que le sautoir 50 est en appui par son talon 60 sur celle des dents 22 de la denture intérieure de l'anneau de quantième 2 qui sépare l'intervalle entre deux dents 22 dans lequel ledit sautoir 50 se trouvait de l'intervalle suivant dans lequel ledit sautoir 50 va tomber. Additionnellement, le sautoir 50 maintient le levier 52 écarté de sa position de repos dans laquelle il bloque ledit sautoir 50.To the Figure 7D , the date mechanism according to the invention is shown in the position immediately preceding the passage of the date indication of a given date, in this case the "16", the next date, here the "17". It can be seen in this figure that the jumper 50 is supported by its heel 60 on that of the teeth 22 of the internal toothing of the date ring 2 which separates the gap between two teeth 22 in which said jumper 50 was located next interval in which said jumper 50 will fall. Additionally, the jumper 50 keeps the lever 52 away from its rest position in which it blocks said jumper 50.

Lorsqu'on passe de la figure 7D à la figure 7E, l'engrenage supérieur du mobile correcteur 9 a fini de faire avancer l'anneau de quantième supérieur 2 et le sautoir 50 est tombé dans l'intervalle entre les deux dents 22 suivantes sous l'effet de la force de rappel élastique du bras 51 a du ressort 51. Lors de son saut, le sautoir 50 devient l'élément moteur de l'anneau de quantième 2 qui finit de pivoter et qui est limité dans son avance par le talon 60 dudit sautoir 50 dont les plans inclinés viennent en contact avec les deux dents 22 suivantes. Simultanément, le levier de blocage 52 remonte le long du flanc 58 du sautoir 50 et à la figure 7F qui représente le mécanisme de quantième selon l'invention après le saut du quantième, l'extrémité du bras 53b du levier de blocage 52 est revenue se loger dans la creusure 56 du sautoir 50, bloquant ainsi à nouveau ce dernier.When we go from Figure 7D to the figure 7E , the upper gear of the corrector 9 has finished advancing the upper date ring 2 and the jumper 50 has fallen in the gap between the two following teeth 22 under the effect of the elastic restoring force of the arm 51 51. During its jump, the jumper 50 becomes the driving element of the date ring 2 which ends to pivot and which is limited in its advance by the heel 60 of said jumper 50 whose inclined planes come into contact with the next two teeth 22. Simultaneously, the locking lever 52 rises along the side 58 of the jumper 50 and at the figure 7F which represents the date mechanism according to the invention after the jump of the date, the end of the arm 53b of the locking lever 52 has returned to lodge in the recess 56 of the jumper 50, thus blocking the latter again.

On constate, au vu de ce qui précède, que l'anneau de quantième supérieur 2 est constamment bloqué et qu'il présente donc une bonne résistance aux chocs et ne risque pas de sauter inopinément. Plus précisément, durant les phases de fonctionnement normal de la montre, le disque de quantième supérieur 2 est maintenu en position de blocage par le levier de blocage 52 et durant les périodes de correction de l'indication de quantième, le disque de quantième 2 est maintenu par l'engrenage supérieur du mobile correcteur 9.In view of the foregoing, it can be seen that the upper date ring 2 is constantly blocked and therefore has good impact resistance and is unlikely to jump unexpectedly. More specifically, during the normal operation phases of the watch, the upper date disk 2 is held in the locking position by the locking lever 52 and during the correction periods of the date indication, the date disk 2 is maintained by the upper gear of the correcting mobile 9.

Dans ce qui précède, on s'est intéressé au disque de quantième supérieur 2. La présente invention s'applique de manière identique à l'anneau de quantième inférieur 3. A cet effet, il est prévu un levier de blocage 52' agencé sous le levier de blocage 52 et monté pivotant autour du même axe que ce dernier. Ce levier de blocage 52' coopère avec la roue 122 du quatrième engrenage multiplicateur 14 et avec un sautoir 50' monté sous le sautoir 50 et pivotant autour du même axe que ce dernier. Le levier de blocage 52' est maintenu contre la roue 122 par un ressort 51b' et le sautoir 50' est maintenu en position d'indexation de l'anneau de quantième inférieur 3 par un ressort 51 a'. Les deux ressorts 51 b' et 51 a' peuvent être séparés ou venir de matière. Il peut même être envisagé, comme représenté à la figure 6, que les quatre ressorts 51 a, 51a', 51 b et 51 b' soient réalisés d'une seule pièce sous la forme de lames élastiques parallèles deux à deux.In the foregoing, we are interested in the upper date disc 2. The present invention applies identically to the lower date ring 3. For this purpose, there is provided a locking lever 52 'arranged under the locking lever 52 and pivotally mounted about the same axis as the latter. This locking lever 52 'cooperates with the wheel 122 of the fourth multiplier gear 14 and with a jumper 50' mounted under the jumper 50 and pivoting about the same axis as the latter. The locking lever 52 'is held against the wheel 122 by a spring 51b' and the jumper 50 'is held in the indexing position of the lower date ring 3 by a spring 51 a'. The two springs 51b 'and 51a' can be separated or come from one another. It can even be considered, as represented in figure 6 , that the four springs 51a, 51a ', 51b and 51b' are made in one piece in the form of elastic blades parallel in pairs.
