Definitions
- the present invention relates to a date mechanism for a timepiece comprising a display crown carrying date indications intended to be designated successively to be read, typically through a window or using a pointer.
- the patent application EP 1,596,261 A1 describes an annual calendar mechanism for a timepiece comprising a calendar display crown with internal toothing bearing indications intended to be read through a window.
- the drive of this display crown in rotation under the window is carried out on the one hand, by the daily actuation of its internal toothing by a first finger of a drive member and on the other hand by the actuation each thirty of the month months of less than thirty-one days of a satellite carried by this crown and situated on a level different from that of the internal toothing of the crown by a second finger of said drive member.
- the date mechanism described in this patent application has the drawback that its display crown comprises means, on the one hand including its internal toothing and on the other hand its month satellite, distinct for its rotational drive, these means on different levels. This takes up a lot of space, especially since the satellite, integral with the display crown, pivots with it.
- European patent application EP 1 666 991 A1 describes an annual calendar mechanism for a timepiece comprising a movable date trainer making a revolution in twenty-four hours, this mobile being equipped with a first finger driving with a step and once a day a first stage of a date crown comprising thirty-one internal teeth, said mobile being equipped with a second finger leading by one step and at the end of one month less thirty-one days one of the five lugs which is fitted with a board secured to an annual wheel arranged coaxially with the date crown, said mechanism further comprising a reference connecting at the end of each month, said annual wheel to a lug arranged inside a second stage of said date crown.
- the mechanism described in this application also has the disadvantage of taking up space.
- its display crown comprises means, including on the one hand its internal toothing and on the other hand the lug which it carries via its second stage, distinct for its rotational drive, these means being located on different levels .
- An object of the present invention is to provide a date mechanism allowing the correct display of the date display at the end of the month, whether the month is a month of thirty days or a month of thirty-one days, said mechanism comprising a display crown of which only the internal toothing, located on a single level, allows it to rotate.
- the invention also relates to a timepiece such as a wristwatch, a pocket watch or a table calendar comprising such a date mechanism.
- the date mechanism according to the invention is typically fixed on a frame such as a plate or a bridge of a watch movement.
- the frame can also be an additional board, the date mechanism and said board typically forming a module. Unless otherwise indicated, the various movements described are described in relation to said frame.
- the month cam typically includes hollowed parts, all of the same depth, and non-hollowed parts, distributed over adjacent angular sectors. It is typically a cam of twelve comprising twelve angular sectors of 30 ° alternating, following the order of the months that they represent, hollowed and non-hollowed angular portions.
- the month cam rotates each month, typically a twelfth of a turn, to present a hollowed-out part to the probe in the months of less than thirty-one days and to present an undeveloped part to the probe in the months of thirty-one and one day.
- rocker spring a spring that is typically fixed on the frame.
- rest position the position of the scale in which its feeler is pressed against the month cam. There are typically two distinct rest positions of the scale, depending on whether the current month comprises thirty-one days or less than thirty-one days, these positions depending on the angular position of the cam of the months relative to the built.
- a date mechanism 1 comprises a date display crown 2, a cam of twelve 3, a rocker 4 comprising a feeler 4a and carrying a pawl 4b, and a wheel 5 of twenty-four hours wearing a finger 6.
- the pawl 4b carried by the rocker 4 is able to pivot around an axis of rotation A3 (virtual or imaginary), fixed relative to the rocker 4.
- the date mechanism 1 is integrated into a timepiece movement comprising a plate 100.
- the date display crown 2 includes indications 7 ranging from one to thirty-one and corresponding to the dates of the months, uniformly distributed over a circumference of its upper surface and intended to be read through a window 8 of which the position is fixed relative to the plate 100.
- the window 8 is typically produced in a dial positioned above the display crown 2. In the figures, although such a dial is not shown for reasons of readability, the position of the window 8 is materialized.
- the rocker 4 is intended to pivot around an axis of rotation O (virtual or imaginary) between a rest position, in which its feeler 4a is held in abutment against the cam of twelve 3, typically by a rocker spring 9 fixed on the plate 100, and a predetermined position called “extreme position” corresponding to the position of the rocker 4 in which the probe 4a is the furthest from the cam of twelve 3.
- O axis of rotation
- the pawl 4b which it carries actuates the display crown 2, the positioning of which is ensured by a positioning device 10 comprising a jumper 10a.
- the end 4b 'of the pawl 4b cooperating with the teeth of the display crown 2 is kept pivoted counterclockwise by a pawl spring 11, fixed on the rocker 4.
- the cam of twelve 3 has hollow parts and solid (or non-hollow) parts, each of which corresponds to a month of the common year.
- the hollow parts of the cam of twelve 3 are all located at the same distance from its axis of rotation A2 (virtual or imaginary) and therefore all have the same depth.
- the solid parts are also all located at the same distance from the axis of rotation A2.
- the cam of twelve 3 rotates at the end of each month by a twelfth of a turn.
- the probe 4a is located at a given position which determines the rest position of the rocker 4. This position determines the amplitude of the pawl 4b of the rocker 4 acting on the internal toothing of the display crown 2.
- the cam of twelve 3 is coaxial and integral in rotation with a star of twelve 16 comprising twelve teeth.
- This star 16 pivots around the axis A2 of a not per month. It is typically positioned by a jumper 17, only part of which is visible in the figures.
- the finger 6 is coaxial with the wheel 5 of twenty-four hours and pivots around the axis of rotation A1 of this wheel 5 at a speed of one revolution per twenty-four hours counterclockwise.
- the twenty-four hour wheel 5 makes one revolution a day.
- it typically meshes with the hour wheel 18 of the clockwork of the timepiece movement in which the date mechanism 1 is integrated.
- a pin 15 fixed on the wheel 5 of twenty-four hours allows the drive of the finger 6 in rotation at a speed of one revolution per twenty-four hours counterclockwise. It is the normal direction of rotation of the hour wheel 18 (here clockwise) which defines the direction of rotation of the wheel 5 and therefore of the finger 6.
- the pin 15 could be replaced by an element, such as '' a retractable lug.
- said element would allow finger 6 to be driven only when the 24-hour wheel 5 would pivot counterclockwise. This would protect the mechanism, for example when setting the time which would consist of moving the time back.
- tooth X / Y the tooth of the display crown 2 located between the indications 7 bearing the numbers X and Y.
- this first special tooth 15/16 comprising a first 13a and a second 13b small teeth which correspond to a tooth classic split in half. Together, these teeth 13a, 13b occupy a width "l", identical to the width of a conventional tooth.
- These small teeth 13a, 13b play a particular role for the passage of dates at the end of the month depending on whether or not the current month is a month of thirty-one days, as explained below.
- the figures 2a to 2d illustrate mechanism 1 in successive states, during the passage from the twenty-eight calendar to the twenty-nine calendar of the month of March.
- the figure 2a illustrates mechanism 1, on March 28 at the end of the day.
- the rocker 4 at rest, its feeler 4a being held in abutment by the rocker spring 9 against an in-hollow part of the cam of twelve 3.
- the pawl 4b is in turn supported on a tooth 13/14 of the internal toothing of the date display crown 2.
- the positioning device 10 of the display crown 2 is pivoted under the effect of this rotation. Even if the extreme position of the lever 4 is not sufficient for the pawl 4b to generate a full pitch rotation of the display crown 2, the positioning device 10 allows the repositioning of the display crown to be date 2. It helps the latter to complete the rotation of a step it started, as illustrated in figure 2c .
- the figure 3 illustrates mechanism 1 on April 1 at the start of the day.
- the rocker 4 at rest, its feeler 4a being held in abutment by the rocker spring 9 against a hollowed-out part of the cam of twelve 3.
- the pawl 4b is in abutment against a tooth of the internal toothing of the date display crown 2, typically in the middle of the width of this tooth, as illustrated in the figure 3 not against the side of that tooth.
- the stages are identical for each standard jump of a month of less than thirty-one days, that is to say for each date change of a month of less than thirty-one days except for the passage from the 30th calendar of this month to the first calendar of the following month.
- mechanism 1 during the transition from the thirty-thirty to the thirty-one calendar of a month then from the thirty-one calendar of this month to the first calendar of the following month in the thirty-one day months is described in more detail below with reference to figures 4a to 4g .
- the figure 4a illustrates mechanism 1 on March 30, at the end of the day.
- the probe 4a of the rocker 4 is in abutment against a solid part of the cam of twelve 3 indicating that it is a month of thirty-one days.
- the pawl 4b is held, by the spring 11, in abutment against the first 13a of the two small teeth 13a, 13b facing it.
- the lever 4 is actuated by the finger 6 of the twenty-four hour wheel 5, it pivots and its pawl 4b drives the display crown 2 in clockwise rotation by acting on the tooth 14/15 of the date crown 2. This is illustrated in figures 4b and 4c .
- the stop 12 prevents the pawl 4b from retracting by pivoting counterclockwise when the rocker 4 is raised ( figure 4b ).
- rocker 4 has reached its extreme position.
- the display in the window 8 shows that the display crown 2 has performed part of its rotation.
- the rest of the rotation of the display crown 2 then occurs under the effect of the positioning device 10 of the display crown 2 which helps said crown 2 to complete its pitch.
- the indication corresponding to the date thirty-one is then fully visible through the window 8, as illustrated in the figure 4c .
- the figure 4d illustrates mechanism 1 several hours later, on March 31, at the end of the day.
- the position of the cam of twelve 3 has not changed.
- the rocker 4 is in the rest position, with its feeler 4a resting against an in-ground part of the cam of twelve 3.
- the finger 6 again raises the rocker 4 and its pawl 4b comes drive the display crown 2 to rotate clockwise by acting this time on the small lower tooth 13b of the date crown 2 between the indications fifteen and sixteen. This is illustrated in figures 4e and 4f .
- rocker 4 has reached its extreme position.
- the display in the window 8 shows that the display crown 2 has performed part of its rotation.
- the rest of the rotation of the display crown then occurs under the effect of the positioning device 10 of the display crown 2, as already explained.
- the indication corresponding to the date "one” is then entirely visible through the window 8, as illustrated in the figure 4f .
- mechanism 1 during the transition from the 30th calendar of a month to the first calendar of the following month in months of less than thirty-one days is described in more detail below with reference to Figures 5a to 5f .
- the figure 5a illustrates mechanism 1 on April 30 at the end of the day.
- the probe 4a of the rocker 4 is in abutment against a hollowed-out part of the cam of twelve 3 indicating that it is a month of less than thirty-one days.
- the end 4b ′ of the pawl 4b is held, by the pawl spring 11, in abutment against the second 13b of the two small teeth facing it, that is to say between the two small teeth 13a, 13b.
- the lever 4 is actuated by the finger 6 of the twenty-four hour wheel 5, it pivots and its pawl 4b drives the display crown 2 in clockwise rotation by acting on the first small tooth 13a of the date crown 2.
- the stop 12 prevents the end 4b 'of the pawl 4b from being retracted during the lifting of the rocker 4. It keeps the end 4b' of the pawl 4b in the trajectory of the first small tooth 13a and therefore participates in the drive of the display crown 2 in rotation.
- rocker 4 has not reached its extreme position.
- the display in the window 8 shows that the display crown 2 has started to rotate one step towards the date display "thirty-one".
- the rest of the rotation of the display crown 2 then occurs under the effect of the positioning device 10 which helps said crown 2 to complete its pitch.
- the pawl 4b retracts and lets the second small tooth 13b pass.
- the indication corresponding to the date thirty-one is then fully visible through the window 8, as illustrated in the figure 5c . But it only lasts a very short time. Indeed, at this stage the rocker 4 continues its rotation clockwise so that the pawl 4b again drives the display crown 2 in clockwise rotation by acting on the second small tooth 13b of the crown of date 2. This is illustrated in the figure 5d .
- rocker 4 has reached its extreme position.
- the display in the window 8 shows that the display crown 2 has carried out part of its rotation by one step towards the display of the date "one".
- the rest of the rotation of the display crown 2 then occurs under the effect of the positioning device 10 of the display crown 2 which helps the latter to complete its pitch.
- the indication corresponding to the date "one” is then entirely visible through the window 8, as illustrated in the figure 5e .
- the second special tooth 14 of the display crown 2 caused the star to rotate one step. of twelve 16 and therefore the positioning of the cam of twelve 3 in a position corresponding to the following month, the month of May, which is a month of thirty-one days.
- the rotation of the star of twelve 16 is illustrated in particular in figures 5d and 5th .
- the date mechanism 1 allows the correct passage of the date display at the end of the month whether the month is a month of thirty days or a month of thirty-one days.
- the months of thirty days, in the night from the thirty to the first, the thirty of the month is followed by the first without manual intervention.
- the date mechanism 1 has the advantage of comprising a display crown of which only the internal toothing, located on a single level, allows it to rotate. It therefore takes up less space than the date mechanisms of this type according to the prior art. In addition, it also has the advantage of requiring only one pawl to actuate the date display crown 2.
- the month cam 3 has twelve angular portions with hollow and non-hollow parts corresponding respectively to months of less than thirty-one days and to months of thirty-one days and is associated with a star of twelve 16 to twelve teeth. It is clear that the month cam could take different forms as long as its function is not impaired. It could in particular comprise a number of angular portions multiple of twelve and be associated with a star comprising a number of teeth corresponding to this number of angular portions. The mechanism could also be adjusted so that the valleys correspond to the months of thirty-one days and the flat parts to the months of less than thirty-one days.
- the date mechanism 1 illustrated in figures 1 to 5f is an annual calendar mechanism and behaves in February as if it were thirty days old.
- the mechanism could be modified so that it behaves in February as if it had thirty-one days.
- a person skilled in the art could easily adapt it, in particular by adding a leap year cam, to make it a perpetual calendar.
- the date mechanism according to the invention is typically fixed on a frame such as a plate or a bridge of a watch movement.
- the date mechanism according to the invention can also have its own frame, typically an additional plate, which can be made integral with the frame of said watch movement.
- date mechanism 1 can be adapted so that the so-called "special" teeth are positioned elsewhere on the internal teeth of the date display crown 2.
- their shape can also be modified as long as their function is preserved.
- the two teeth 13a, 13b of the first special tooth 13 of width "l” may not have the same width so that the recess separating them would not be located in the middle of the width "l” of the first special tooth 13 but at a distance corresponding to x% of "l” with respect to one end of this tooth 13, the position of this end being considered with respect to a predetermined direction of rotation.
- the mechanism 1 would then be adapted so that, during the dates one to twenty-nine months of less than thirty-one days, the end 4b ′ of the pawl 4b is positioned in abutment against a tooth of the internal toothing of the display crown 2, at the same distance of x% of "l” from the end of this tooth considered with respect to the same predetermined direction of rotation.
- the positioning device 10 illustrated in the figures 1 to 5f is a device comprising a jumper 10a associated with a mobile, said mobile comprising a five-tooth star 10b and a wide-toothed wheel 10c.
- the width of the teeth of said wide-toothed wheel 10c typically corresponds to the distance separating two teeth from the internal toothing of the date crown 2.
- the five-tooth star is positioned by a "classic" jumper 10a fixed on the plate 100 and the wide-toothed wheel 10c cooperates with the teeth of the display crown 2.
- Such a positioning device 10 could be replaced by a conventional jumper (such as the jumper 10a).
- the pawl 4b could have come in one piece with the rocker 4 while remaining mobile in rotation relative to this rocker 4.
- the twenty-four hour wheel 5 could be rotated other than via the hour wheel 18 of the clockwork train of the watch movement in which the mechanism 1 is integrated.
- the positioning device 10 participates in the rotation of the display crown 2, the lever not having to generate alone the displacement of a complete pitch of the crown d 'display 2. This is to limit the energy consumption required to lift the lever 4.

L'invention propose à cette fin un mécanisme de quantième comprenant une couronne d'affichage à denture intérieure portant des indications allant de un à trente-et-un destinées à être désignées successivement pour indiquer le quantième du mois, une dent de la denture intérieure de la couronne d'affichage étant remplacée par un organe d'entraînement de forme différente de celle des dents de ladite denture, une came des mois dont la position angulaire est indicative du nombre de jours dans le mois en cours et une bascule comprenant un palpeur et un cliquet, ladite bascule étant destinée à être entraînée en rotation, depuis une position dans laquelle son palpeur est en appui contre ladite came des mois, cette position dépendant du nombre de jours dans le mois, vers une position prédéterminée, le tout étant agencé de sorte que :
- quel que soit le nombre de jours du mois en cours, lorsque le quantième du mois est compris entre un et vingt-neuf inclus, à chaque rotation de la bascule depuis la position dans laquelle son palpeur est en appui contre la came des mois vers ladite position prédéterminée, le cliquet coopère avec une dent de la denture intérieure de la couronne d'affichage, pour entraîner la rotation d'un pas de ladite couronne d'affichage, l'indication de quantième désignée étant ainsi incrémentée d'une unité ;
- lorsque le quantième du mois est égal à trente :
- ∘ si le mois en cours est un mois de trente jours, sous l'effet de la rotation de la bascule depuis la position dans laquelle son palpeur est en appui contre la came des mois, le cliquet coopère avec une première partie de l'organe d'entraînement pour entraîner la rotation d'un premier pas de ladite couronne d'affichage puis coopère avec une dent de la denture intérieure de la couronne d'affichage adjacente à l'organe d'entraînement pour entraîner d'un second pas la couronne d'affichage, l'indication de quantième désignée passant ainsi de trente à trente-et-un puis de trente-et-un à un consécutivement ; et
- ∘ si le mois en cours est un mois de trente-et-un jours, sous l'effet de la rotation de la bascule depuis la position dans laquelle son palpeur est en appui contre la came des mois vers ladite position prédéterminée, le cliquet coopère avec une dent de la denture intérieure de la couronne d'affichage adjacente à l'organe d'entraînement pour entraîner la rotation d'un pas de ladite couronne d'affichage, l'indication de quantième désignée passant ainsi de trente à trente-et-un.
- lorsque le quantième du mois est égal à trente-et-un, sous l'effet de la rotation de la bascule depuis la position dans laquelle son palpeur est en appui contre la came des mois vers ladite position prédéterminée, le cliquet coopère avec une seconde partie de l'organe d'entraînement pour entraîner la rotation d'un pas de ladite couronne d'affichage, l'indication de quantième désignée passant ainsi de trente-et-un à un.
- regardless of the number of days in the current month, when the calendar of the month is between one and twenty-nine inclusive, each rotation of the scale from the position in which its feeler is pressed against the cam of the months towards said predetermined position, the pawl cooperates with a tooth of the internal toothing of the display crown, to cause the rotation of one step of said display crown, the designated date indication thus being incremented by one;
- when the calendar of the month is equal to thirty:
- ∘ if the current month is a month of thirty days, under the effect of the rotation of the scale from the position in which its feeler is in abutment against the cam for months, the pawl cooperates with a first part of the organ drive to drive the rotation of a first step of said display crown and then cooperates with a tooth of the internal toothing of the display crown adjacent to the drive member to drive the crown a second step display, the designated date indication thus going from thirty to thirty-one then from thirty-one to one consecutively; and
- ∘ if the current month is a month of thirty-one days, under the effect of the rotation of the rocker from the position in which its probe is pressing against the cam for months towards said predetermined position, the pawl cooperates with a tooth of the internal toothing of the display crown adjacent to the drive member for driving the rotation of one step of said display crown, the designated date indication thus passing from thirty to thirty-and -a.
- when the calendar of the month is equal to thirty-one, under the effect of the rotation of the scale from the position in which its probe is pressing against the month cam to said predetermined position, the pawl cooperates with a second part of the drive member for driving the rotation of one step of said display crown, the designated date indication thus going from thirty-one to one.
L'invention concerne également une pièce d'horlogerie telle qu'une montre bracelet, une montre de poche ou un calendrier de table comprenant un tel mécanisme de quantième.The invention also relates to a timepiece such as a wristwatch, a pocket watch or a table calendar comprising such a date mechanism.
Le mécanisme de quantième selon l'invention est typiquement fixé sur un bâti tel qu'une platine ou un pont d'un mouvement horloger. Le bâti peut également être une planche additionnelle, le mécanisme de quantième et ladite planche formant typiquement un module. Sauf indication contraire, les différents mouvements décrits sont décrits relativement audit bâti.The date mechanism according to the invention is typically fixed on a frame such as a plate or a bridge of a watch movement. The frame can also be an additional board, the date mechanism and said board typically forming a module. Unless otherwise indicated, the various movements described are described in relation to said frame.
La came des mois comprend typiquement des parties creusées, toutes de même profondeur, et des parties non creusées, réparties sur des secteurs angulaires adjacents. Il s'agit typiquement d'une came de douze comprenant douze secteurs angulaires de 30° alternant, en suivant l'ordre des mois qu'elles représentent, des portions angulaires creusées et non creusées. La came des mois pivote chaque mois, typiquement d'un douzième de tour, pour présenter une partie creusée au palpeur lors des mois de moins de trente-et-un jours et pour présenter une partie non creusée au palpeur lors des mois de trente-et-un jours.The month cam typically includes hollowed parts, all of the same depth, and non-hollowed parts, distributed over adjacent angular sectors. It is typically a cam of twelve comprising twelve angular sectors of 30 ° alternating, following the order of the months that they represent, hollowed and non-hollowed angular portions. The month cam rotates each month, typically a twelfth of a turn, to present a hollowed-out part to the probe in the months of less than thirty-one days and to present an undeveloped part to the probe in the months of thirty-one and one day.
Le palpeur de la bascule est typiquement maintenu en appui contre la came des mois par le biais d'un ressort dit « ressort de bascule », ce ressort étant typiquement fixé sur le bâti. Selon que le mois en cours comprenne trente-et-un jours ou moins, la position de la bascule dans laquelle son palpeur est en appui contre la came des mois, appelée « position de repos », varie. Il existe typiquement deux positions de repos distinctes de la bascule, selon que le mois en cours comprenne trente-et-un jours ou moins de trente-et-un jours, ces positions dépendant de la position angulaire de la came des mois par rapport au bâti.The rocker probe is typically held in abutment against the month cam by means of a spring called “rocker spring”, this spring being typically fixed on the frame. Depending on whether the current month includes thirty-one days or less, the position of the scale in which its feeler is pressed against the month cam, called "rest position", varies. There are typically two distinct rest positions of the scale, depending on whether the current month comprises thirty-one days or less than thirty-one days, these positions depending on the angular position of the cam of the months relative to the built.
L'expression « couronne à denture intérieure » désigne un anneau à denture intérieure. Il s'agit typiquement d'un disque creux comportant des dents uniformément réparties sur son contour intérieur.The expression “crown with internal teeth” designates a ring with internal teeth. It is typically a hollow disc having teeth uniformly distributed around its inner contour.

Le cliquet 4b porté par la bascule 4 est apte à pivoter autour d'un axe de rotation A3 (virtuel ou imaginaire), fixe par rapport à la bascule 4.The
Le mécanisme de quantième 1 est intégré dans un mouvement horloger comprenant une platine 100.The
La couronne d'affichage de quantième 2 comporte des indications 7 allant de un à trente-et-un et correspondant aux quantièmes des mois, uniformément réparties sur une circonférence de sa surface supérieure et destinées à être lues au travers d'un guichet 8 dont la position est fixe par rapport à la platine 100. Le guichet 8 est typiquement réalisé dans un cadran positionné au-dessus de la couronne d'affichage 2. Dans les figures, bien qu'un tel cadran ne soit pas représenté pour des raisons de lisibilité, la position du guichet 8 est quant à elle matérialisée.The
La bascule 4 est destinée à pivoter autour d'un axe de rotation O (virtuel ou imaginaire) entre une position de repos, dans laquelle son palpeur 4a est maintenu en appui contre la came de douze 3, typiquement par un ressort de bascule 9 fixé sur la platine 100, et une position prédéterminée dite « position extrême » correspondant à la position de la bascule 4 dans laquelle le palpeur 4a est le plus éloigné de la came de douze 3.The
Le passage de la position de repos à la position extrême s'effectue, chaque vingt-quatre heures, sous l'effet du doigt 6 pivotant autour d'un axe de rotation A1 (virtuel ou imaginaire) à une vitesse d'un tour par vingt-quatre heures dans le sens antihoraire, ce doigt 6 venant pousser la bascule 4 en agissant sur une de ses extrémités 4c.The transition from the rest position to the extreme position is carried out, every twenty-four hours, under the effect of the
Lors du pivotement de la bascule 4, le cliquet 4b qu'elle porte actionne la couronne d'affichage 2 dont le positionnement est assuré par un dispositif de positionnement 10 comprenant un sautoir 10a. L'extrémité 4b' du cliquet 4b coopérant avec la denture de la couronne d'affichage 2 est maintenue pivotée dans le sens antihoraire par un ressort de cliquet 11, fixé sur la bascule 4.During the pivoting of the
La came de douze 3 possède des parties creuses et des parties pleines (ou non creuses), chacune d'elles correspondant à un mois de l'année commune. Les parties creuses de la came de douze 3 sont toutes situées à la même distance de son axe de rotation A2 (virtuel ou imaginaire) et ont donc toutes la même profondeur. De même, les parties pleines sont également toutes situées à la même distance de l'axe de rotation A2. La came de douze 3 pivote à chaque fin de mois d'un douzième de tour.The cam of twelve 3 has hollow parts and solid (or non-hollow) parts, each of which corresponds to a month of the common year. The hollow parts of the cam of twelve 3 are all located at the same distance from its axis of rotation A2 (virtual or imaginary) and therefore all have the same depth. Likewise, the solid parts are also all located at the same distance from the axis of rotation A2. The cam of twelve 3 rotates at the end of each month by a twelfth of a turn.
Selon la position angulaire de la came de douze 3, le palpeur 4a se situe à une position donnée qui détermine la position de repos de la bascule 4. Cette position détermine l'amplitude du cliquet 4b de la bascule 4 agissant sur la denture intérieure de la couronne d'affichage 2. Il existe typiquement deux positions de repos distinctes de la bascule 4, selon que le mois en cours comprenne trente-et-un jours ou moins de trente-et-un jours. Par exemple, une première de ces positions est représentée à la
La came de douze 3 est coaxiale et solidaire en rotation d'une étoile de douze 16 comprenant douze dents. Cette étoile 16 pivote autour de l'axe A2 d'un pas par mois. Elle est typiquement positionnée par un sautoir 17 dont seule une partie est visible sur les figures.The cam of twelve 3 is coaxial and integral in rotation with a star of twelve 16 comprising twelve teeth. This star 16 pivots around the axis A2 of a not per month. It is typically positioned by a
Le doigt 6 est coaxial de la roue 5 de vingt-quatre heures et pivote autour de l'axe de rotation A1 de cette roue 5 à une vitesse d'un tour par vingt-quatre heures dans le sens antihoraire. Comme son nom l'indique, la roue 5 de vingt-quatre heures effectue un tour par jour. Pour cela, elle engrène typiquement avec la roue des heures 18 du rouage de minuterie du mouvement horloger dans lequel le mécanisme de quantième 1 est intégré. Une goupille 15 fixée sur la roue 5 de vingt-quatre heures permet l'entraînement du doigt 6 en rotation à une vitesse d'un tour par vingt-quatre heures dans le sens antihoraire. C'est le sens de rotation normal de la roue des heures 18 (ici sens horaire) qui définit le sens de rotation de la roue 5 et donc du doigt 6. En variante, la goupille 15 pourrait être remplacée par un élément, tel qu'un ergot, escamotable. Dans ce cas, ledit élément ne permettrait l'entraînement du doigt 6 que lorsque la roue 5 de vingt-quatre heures pivoterait dans le sens antihoraire. Cela permettrait de protéger le mécanisme, par exemple lors d'un réglage de l'heure qui consisterait à reculer l'heure.The
Dans la suite de la description, pour faciliter la compréhension de l'invention, nous appellerons, en référence aux
Entre les indications quinze et seize de la couronne d'affichage 2 se trouve une première dent (15/16) spéciale en deux parties, cette première dent spéciale 15/16 comprenant une première 13a et une seconde 13b petites dents qui correspondent à une dent classique séparée en deux. A elles deux, ces dents 13a, 13b occupent une largeur « l », identique à la largeur d'une dent classique. Ces petites dents 13a, 13b jouent un rôle particulier pour le passage des quantièmes en fin de mois selon que le mois en cours soit ou non un mois de trente-et-un jours, comme expliqué plus loin.Between the indications fifteen and sixteen of the
Entre les indications vingt et vingt-et-un se trouve une seconde dent spéciale 20/21, différente de la première et plus longue que les autres de manière à permettre l'entraînement de l'étoile 16 de douze d'un pas chaque mois.Between the indications twenty and twenty-one is a second
A l'exception de ces dents « spéciales » 13a, 13b et 14, toutes les autres dents de la couronne d'affichage 2 ou « dents classiques » sont identiques ou sensiblement identiques entre elles. Elles ont une largeur « l ».With the exception of these “special”

Lorsque la bascule 4 est entraînée en rotation par le doigt 6, l'extrémité 4b' du cliquet 4b vient en butée contre la dent 12/13 de la couronne d'affichage de quantième 2 pour la lever. Dans un premier temps, le cliquet 4b pivote dans le sens antihoraire jusqu'à ce que ce pivotement soit bloqué par une butée 12 fixée sur la bascule 4. Le couple nécessaire pour entraîner la rotation de la couronne d'affichage 2 est typiquement défini par le dispositif de positionnement 10.When the
Comme la bascule 4 continue de pivoter, le cliquet 4b qui ne peut pas pivoter davantage dans le sens antihoraire pousse la dent 12/13 se trouvant immédiatement à côté de lui, ce qui entraîne la rotation de la couronne d'affichage de quantième 2 dans le sens horaire, comme illustré à la
Le dispositif de positionnement 10 de la couronne d'affichage 2 est pivoté sous l'effet de cette rotation. Même si la position extrême de la bascule 4 n'est pas suffisante pour que le cliquet 4b engendre la rotation d'un pas complet de la couronne d'affichage 2, le dispositif de positionnement 10 permet le repositionnement de la couronne d'affichage de quantième 2. Il aide cette dernière à terminer la rotation d'un pas qu'elle a débuté, comme illustré à la
Alors que la position extrême de la bascule 4 est atteinte, le doigt 6 continue à pivoter. Aussi, la pression qu'il exerce sur l'extrémité 4c de la bascule 4 fini par disparaître, si bien que celle-ci retourne vers sa position de repos, sous l'effet du ressort 9 de bascule.While the extreme position of the
Lorsque la bascule 4 pivote vers sa position de repos, le cliquet 4b s'escamote contre la force de rappel élastique de son ressort 11 pour laisser passer la dent 13/14 sans perturber la position de la couronne de quantième 2.When the

Les étapes sont identiques pour chaque saut standard d'un mois de trente-et-un jours c'est-à-dire pour chaque passage de quantième d'un mois de trente-et-un jours sauf pour le passage du quantième trente au quantième trente-et-un de ce mois puis du quantième trente-et-un de ce mois au premier quantième du mois suivant. Ces étapes particulières associées aux fins de mois sont expliquées plus loin dans la description.The steps are identical for each standard jump of a month of thirty-one days, that is to say for each change of date from a month of thirty-one days except for the change from the date thirty to one calendar thirty-one of this month then from calendar thirty-one of this month to the first calendar of the following month. These particular milestones associated with the end of the month are explained later in the description.

A partir de cette position de repos, lorsque la bascule 4 sera pivotée, sous l'effet du doigt 6, le cliquet 4b commencera par glisser contre la dent 17/18 contre laquelle il est en appui sans la déplacer puis poussera la dent 16/17 suivante, ce qui entraînera la rotation de la couronne d'affichage de quantième 2 dans le sens horaire. Les étapes suivantes sont les mêmes que celles décrites lors d'un saut standard d'un mois de trente-et-un jours. Lorsque la bascule 4 reviendra vers sa position de repos, le cliquet 4b s'escamotera contre la force de rappel élastique de son ressort 11 pour laisser passer la dent 17/18. Il viendra ainsi se positionner contre la dent 18/19, typiquement au milieu de la largeur de cette dent 18/19.From this rest position, when the
Les étapes sont identiques pour chaque saut standard d'un mois de moins de trente-et-un jours c'est-à-dire pour chaque passage de quantième d'un mois de moins de trente-et-un jours sauf pour le passage du quantième trente de ce mois au premier quantième du mois suivant.

De plus, lors de la rotation de la couronne d'affichage de quantième 2, entre le trente avril et le premier mai, la seconde dent spéciale 14 de la couronne d'affichage 2 a entraîné la rotation d'un pas de l'étoile de douze 16 et donc le positionnement de la came de douze 3 dans une position correspondant au mois suivant, le mois de mai, qui est un mois de trente-et-un jours. La rotation de l'étoile de douze 16 est illustrée notamment aux
Le mécanisme de quantième 1 selon l'invention permet le passage correct de l'affichage de quantième en fin de mois que le mois soit un mois de trente jours ou un mois de trente-et-un jours. Les mois de trente jours, dans la nuit du trente au premier, le trente du mois est suivi du premier sans intervention manuelle.The
Pour obtenir cela, le mécanisme de quantième 1 présente l'avantage de comprendre une couronne d'affichage dont seule la denture intérieure, située sur un seul niveau, permet sa mise en rotation. Il prend donc moins d'espace que les mécanismes de quantième de ce type selon l'art antérieur. De plus, il présente également l'avantage de ne nécessiter qu'un seul cliquet pour l'actionnement de la couronne d'affichage de quantième 2.To obtain this, the
Il apparaîtra clairement à l'homme du métier que la présente invention n'est en aucun cas limitée au mode de réalisation présenté ci-dessus et illustré dans les figures.It will be clear to those skilled in the art that the present invention is in no way limited to the embodiment presented above and illustrated in the figures.
Dans le mode de réalisation illustré, la came des mois 3 comporte douze portions angulaires avec des parties creuses et non creuses correspondants respectivement aux mois de moins de trente-et-un jours et aux mois de trente-et-un jours et est associée à une étoile de douze 16 à douze dents. Il est clair que la came des mois pourrait prendre des formes différentes pour autant que sa fonction ne soit pas altérée. Elle pourrait notamment comprendre un nombre de portions angulaires multiple de douze et être associée à une étoile comprenant un nombre de dents correspondant à ce nombre de portions angulaires. Le mécanisme pourrait également être ajusté pour que les creux correspondent aux mois de trente-et-un jours et les parties planes aux mois de moins de trente-et-un jours.In the illustrated embodiment, the
Le mécanisme de quantième 1 illustré aux
Comme indiqué précédemment, le mécanisme de quantième selon l'invention est typiquement fixé sur un bâti tel qu'une platine ou un pont d'un mouvement horloger. Le mécanisme de quantième selon l'invention peut également posséder son propre bâti, typiquement une planche additionnelle, qui pourra être rendu solidaire du bâti dudit mouvement horloger.As indicated previously, the date mechanism according to the invention is typically fixed on a frame such as a plate or a bridge of a watch movement. The date mechanism according to the invention can also have its own frame, typically an additional plate, which can be made integral with the frame of said watch movement.
Il semble en outre évident que le mécanisme de quantième 1 peut être adapté pour que les dents dites « spéciales » soient positionnées ailleurs sur la denture intérieure de la couronne d'affichage de quantième 2. De plus, leur forme peut également être modifiée tant que leur fonction est conservée.It also seems obvious that the
Typiquement, les deux dents 13a, 13b de la première dent spéciale 13 de largeur « l » pourraient ne pas avoir la même largeur de sorte que la creusure les séparant ne se situerait pas au milieu de la largeur « l » de la première dent spéciale 13 mais à une distance correspondant à x% de « l » par rapport à une extrémité de cette dent 13, la position de cette extrémité étant considérée par rapport à un sens de rotation prédéterminé. Le mécanisme 1 serait alors adapté pour que, lors des quantièmes un à vingt-neuf des mois de moins de trente-et-un jours, l'extrémité 4b' du cliquet 4b se positionne en appui contre une dent de la denture intérieure de la couronne d'affichage 2, à une même distance de x% de « l » à partir de l'extrémité de cette dent considérée par rapport au même sens de rotation prédéterminé.Typically, the two

Bien évidemment, les sens de pivotement des différents organes pourraient être modifiés.Obviously, the directions of pivoting of the various members could be modified.
Dans d'autres variantes, il est évident que la forme des différents organes décrits peut varier à l'infini pour autant que leurs fonctions soient assurées.In other variants, it is obvious that the shape of the various organs described can vary infinitely provided that their functions are ensured.
Dans le mode de réalisation décrit, le dispositif de positionnement 10 participe à la mise en rotation de la couronne d'affichage 2, la bascule n'ayant pas besoin d'engendrer à elle seule le déplacement d'un pas complet de la couronne d'affichage 2. Cela a pour but de limiter la consommation d'énergie nécessaire pour lever la bascule 4. Cependant, il est très bien envisageable de concevoir le mécanisme de quantième selon l'invention de sorte que la bascule 4 puisse, à elle seule, via son cliquet 4b, engendrer la rotation d'un pas complet de la couronne d'affichage 2.In the embodiment described, the
