Description

La présente invention est relative à un mécanisme de quantième annuel pour pièce d'horlogerie comportant un mobile entraîneur de quantième faisant un tour en vingt-quatre heures, ce mobile étant équipé d'un premier doigt entraînant d'un pas et une fois par jour un premier étage d'un anneau de quantième comportant trente et une dents intérieures, ledit mobile étant équipé d'un second doigt entraînant d'un pas et à la fin d'un mois de moins de trente et un jours l'un des cinq ergots dont est munie une planche solidaire d'une roue annuelle disposée coaxialement à l'anneau de quantième, ledit mécanisme comportant en outre un renvoi reliant à la fin de chaque mois, ladite roue annuelle à un second étage dudit anneau de quantième.The present invention relates to an annual calendar mechanism for a timepiece comprising a date-driven mobile moving around in twenty-four hours, this mobile being equipped with a first finger causing a step and once a day. a first stage of a date ring having thirty-one inner teeth, said mobile being equipped with a second finger causing a step and at the end of a month of less than thirty-one days one of the five pins which is provided with a board integral with an annual wheel arranged coaxially with the date ring, said mechanism further comprising a reference connecting at the end of each month, said annual wheel to a second stage of said date ring.

Des éléments contenus dans la définition ci-dessus sont connus des documents EP-A-1 251 412 et CH-B-684 815 . On retrouve dans ces documents un mobile entraîneur de quantième faisant un tour en vingt-quatre heures. Dans les deux documents ce mobile entraîneur est équipé d'un premier doigt entraînant d'un pas et une fois par jour un affichage de quantième et d'un second doigt entraînant d'un pas et à la fin d'un mois de moins de trente et un jours l'un des cinq ergots dont est munie une planche solidaire d'une roue annuelle. On retrouve également dans ces documents une roue intermédiaire ou renvoi qui relie, à la fin de chaque mois, la roue annuelle à l'affichage du quantième.Elements contained in the definition above are known from the documents EP-A-1,251,412 and CH-B-684 815 . We find in these documents a mobile date coach making a turn in twenty-four hours. In both documents this mobile trainer is equipped with a first finger taking a step and once a day a date display and a second finger causing a step and at the end of a month less than thirty-one days one of the five lugs which is provided with a board integral with an annual wheel. Also included in these documents an intermediate wheel or referral which connects, at the end of each month, the annual wheel to the display of the date.

Plus particulièrement, le document EP-A-1 251 412 met en oeuvre un anneau à deux étages supportant l'affichage du quantième et une roue annuelle disposée coaxialement audit anneau. Un premier doigt du mobile entraîneur est en prise avec les trente et une dents intérieures d'un premier étage de l'anneau , un second doigt se trouvant situé à la fin d'un mois de moins de trente et un jours sur le chemin d'une planche à cinq ergots sur laquelle est fixée une roue annuelle comportant dix-sept dents. Cette roue annuelle est en prise avec un renvoi comportant également dix-sept dents dont sept sont amincies. Le second étage de l'anneau porte deux dents intérieures l'une de ces dents étant plus mince que l'autre. Le tout est arrangé de telle façon qu'à la fin des mois de trente et un jours la roue annuelle avance d'un pas et qu'à la fin des mois de moins de trente et un jours, ladite roue avance de deux pas. Il s'en suit que l'indicateur des mois comporte dix-sept secteurs égaux. Le nom des mois de trente et un jours (janvier, mars, mai, juillet, août, octobre, décembre) figure une fois et le nom des mois de moins de trente et un jours (février, avril, juin, septembre, novembre) figure deux fois au travers d'un guichet découpé dans le cadran de la pièce d'horlogerie.More particularly, the document EP-A-1,251,412 uses a two-stage ring supporting the display of the date and an annual wheel arranged coaxially with said ring. A first finger of the mobile trainer is engaged with the thirty-one inner teeth of a first stage of the ring, a second finger being located at the end of a month of less than thirty-one days on the road. a five-pin board on which is fixed an annual wheel with seventeen teeth. This annual wheel is engaged with a referral also comprising seventeen teeth, seven of which are thinned. The second stage of the ring carries two inner teeth, one of these teeth being thinner than the other. Everything is arranged in such a way that at the end of the thirty-one days the annual wheel advances one step and that at the end of the months of less than thirty-one days, the wheel advances by two steps. It follows that the month indicator has seventeen equal sectors. The names of the thirty-one-day months (January, March, May, July, August, October, December) appear once and the names of the months of less than thirty-one days (February, April, June, September, November) figure twice through a window cut in the dial of the timepiece.

Le mécanisme qui vient d'être décrit présente l'inconvénient d'un indicateur mensuel hybride, les mois de trente et un jours n'apparaissant qu'une fois au travers du guichet alors que les mois de moins de trente et un jours y apparaissent deux fois. De plus ce mécanisme nécessite l'utilisation d'un renvoi relativement complexe puisque des dix-sept dents dont il est pourvu, dix sont épaisses et sept sont amincies, ce qui conduit à un usinage particulier et complexe de ce renvoi. Ce mécanisme nécessite encore la présence, sur le second étage de l'anneau, de deux ergots situés à des niveaux différents ce qui complique la façon de réaliser cet étage. Enfin on mentionnera que, lors du montage de ce mécanisme, le renvoi doit être placé dans une position angulaire bien précise pour assurer une synchronisation correcte des affichages du quantième et du mois correspondant.The mechanism that has just been described has the drawback of a hybrid monthly indicator, the thirty-one days appearing only once through the counter while the months of less than thirty-one days appear therein. twice. In addition this mechanism requires the use of a relatively complex reference since seventeen teeth which it is provided, ten are thick and seven are thinned, which leads to a particular and complex machining of this reference. This mechanism still requires the presence, on the second stage of the ring, two lugs located at different levels which complicates the way to achieve this floor. Finally, it will be mentioned that, during the assembly of this mechanism, the return must be placed in a precise angular position to ensure correct synchronization of the displays of the date and the corresponding month.

Le document CH-B-684815 met en oeuvre plus particulièrement un quantième annuel où l'affichage de la date est une aiguille. Dans cette exécution, la roue annuelle n'est pas centrale, mais déportée sur le haut de la pièce d'horlogerie. Cela conduit à un mécanisme compliqué, le nom des mois apparaissant sur un disque décentré en prise avec un renvoi comportant trente et une dents dont trente sont tronquées.The document CH-B-684 815 particularly implements an annual calendar where the display of the date is a needle. In this embodiment, the annual wheel is not central, but offset on the top of the timepiece. This leads to a complicated mechanism, the names of the months appearing on an off-center disc grappling with a reference with thirty-one teeth, thirty of which are truncated.

Pour obvier aux inconvénients des documents cités ci-dessus, la présente invention, outre qu'elle obéit à la définition générique exprimée au premier paragraphe de cette description, est remarquable en ce que la roue annuelle comporte deux fois plus de dents que l'année comporte de mois et que le renvoi comprend une première roue en prise avec la roue annuelle et une deuxième roue fixée solidairement sur et disposée coxialement à la première, cette deuxième roue étant en prise, à la fin de chaque mois, avec un ergot disposé à l'intérieur du second étage de l'anneau de quantième.To obviate the disadvantages of the documents cited above, the present invention, in addition to fulfilling the generic definition expressed in the first paragraph of this description, is remarkable in that the annual wheel has twice as many teeth as the year comprises month and the return includes a first wheel engaged with the annual wheel and a second wheel fixed integrally on and disposed coxialement to the first, the second wheel being engaged at the end of each month, with a lug arranged to inside the second floor of the date ring.

On va décrire maintenant, à l'aide des figures 1 à 8, un mécanisme de quantième annuel exécuté selon un premier mode d'utilisation de l'invention.We will describe now, with the help of Figures 1 to 8 , an annual calendar mechanism executed according to a first mode of use of the invention.

Ce mécanisme comporte de manière connue un mobile 1 entraîneur de quantième faisant un tour en vingt-quatre heures. Ce mobile 1 tire la force motrice agissant sur lui d'une chaîne cinématique entraînée par le mouvement de la pièce d'horlogerie dont le dernier maillon est illustré par la roue 15. Le mobile 1 est équipé d'un premier doigt 2 qui entraîne d'un pas et une fois par jour à minuit un premier étage 3 d'un anneau de quantième 4 portant trente et une dents intérieures dont trois portent les références 10, 11, 12. Le mobile 1 est encore équipé d'un second doigt 5 qui entraîne d'un pas et à la fin de chaque mois comptant moins de trente et un jours une planche 6 par l'un des ses cinq ergots 20 à 24 (voir figure 3). La planche 6 est solidaire d'une roue annuelle 7, l'ensemble 6, 7 étant disposé coaxialement à l'anneau de quantième 4. Les figures montrent enfin que le mécanisme de quantième annuel comporte en outre un renvoi 8 qui relie, à la fin de chaque mois, la roue annuelle 7 à un second étage 9 de l'anneau de quantième 4.This mechanism comprises, in a known manner, a mobile 1 day trainer making a turn in twenty-four hours. This mobile 1 draws the driving force acting on it of a kinematic chain driven by the movement of the timepiece whose last link is illustrated by the wheel 15. The mobile 1 is equipped with a first finger 2 which leads d a step and once a day at midnight a first stage 3 of a date ring 4 carrying thirty-one inner teeth, three of which bear the references 10, 11, 12. The mobile 1 is still equipped with a second finger which leads one step and at the end of each month with less than thirty-one days a board 6 by one of its five pins 20 to 24 (see figure 3 ). The board 6 is integral with an annual wheel 7, the assembly 6, 7 being disposed coaxially to the ring 4. The figures finally show that the annual calendar mechanism further comprises a reference 8 which connects, at the end of each month, the annual wheel 7 to a second stage 9 of the date ring 4.

Par rapport à ce qui vient d'être dit ci-dessus, le mécanisme de la présente invention se distingue par deux dispositions remarquables et originales. Il s'agit d'abord de la roue annuelle 7 qui comporte deux fois plus de dents 30 que l'année comporte de mois. En d'autres termes, la roue annuelle 7 comprend vingt-quatre dents 30. Il s'agit enfin du renvoi 8 qui comprend une première roue 40 en prise avec la roue annuelle 7, les dents 30 de cette dernière engrenant avec les dents 41 de la première roue 40. Le renvoi 8 comprend encore une deuxième roue 50 fixée sur et disposée coaxialement à la première roue 40. Cette deuxième roue 50 est en prise, à la fin de chaque mois, avec un ergot 60 disposé à l'intérieur du second étage 9 de l'anneau de quantième 4. Les figures montrent que l'ergot 60 est entraîné par les dents 51 qui comprend la deuxième roue 50.Compared with what has just been said above, the mechanism of the present invention is distinguished by two remarkable and original arrangements. It is first of all the annual wheel 7 which has twice as many teeth 30 as the year comprises of months. In other words, the annual wheel 7 comprises twenty-four teeth 30. It is finally the reference 8 which comprises a first wheel 40 in engagement with the annual wheel 7, the teeth 30 of the latter meshing with the teeth 41 of the first wheel 40. The reference 8 further comprises a second wheel 50 fixed on and arranged coaxially with the first wheel 40. This second wheel 50 is engaged at the end of each month, with a lug 60 arranged inside. of the second stage 9 of the date ring 4. The figures show that the lug 60 is driven by the teeth 51 which comprises the second wheel 50.

On remarquera ici que les deux roues 40 et 50 qui forment le renvoi 8 sont munies de dents 41, respectivement 51, régulièrement réparties sur le pourtour des roues correspondantes ce qui conduit à un usinage très classique, ceci contrairement à l'usinage mis en oeuvre pour le renvoi du document EP-A-1 251 412 cité plus haut. La même remarque peut être faite au sujet de l'ergot 60 disposé à l'intérieur du second étage 9 de l'anneau de quantième 4, cet ergot étant unique contrairement aux deux ergots situés sur deux niveaux différents et nécessaires au fonctionnement du quantième équipant le document cité.It will be noted here that the two wheels 40 and 50 which form the reference 8 are provided with teeth 41, respectively 51, regularly distributed around the periphery of the corresponding wheels, which leads to a very conventional machining, this in contrast to the machining employed. for returning the document EP-A-1,251,412 cited above. The same remark can be made about the lug 60 disposed inside the second floor 9 of the date ring 4, this lug being unique in contrast to the two lugs located on two different levels and necessary for the operation of the equipping calendar. the document cited.

Les figures 1 à 8 montrent encore que l'anneau de quantième 4 porte un anneau indicateur de quantième 25 sur lequel sont apposés trente et un chiffres 26. Ces chiffres apparaissent à tour de rôle au travers d'un guichet 27 découpé dans un cadran 28 qui porte la pièce d'horlogerie.The Figures 1 to 8 show again that the date ring 4 carries a date indicator ring 25 on which are affixed thirty-one numbers 26. These figures appear in turn through a window 27 cut in a dial 28 which carries the piece of watchmaking.

Les mêmes figures montrent aussi que la roue annuelle 7 porte un disque indicateur des mois 16 sur lequel sont apposés les noms des douze mois de l'année 17. Ces noms apparaissent chaque mois deux fois et à tour de rôle au travers d'un guichet 18 découpé dans le cadran 28. On s'aperçoit que le disque indicateur du mois comporte donc vingt-quatre secteurs égaux.The same figures also show that the annual wheel 7 carries a disc indicator of months 16 on which are affixed the names of the twelve months of the year 17. These names appear each month twice and in turn through a wicket 18 cut into the dial 28. We see that the indicator disc of the month thus comprises twenty-four equal sectors.

On va décrire maintenant le fonctionnement du quantième annuel en s'aidant des figures 1 à 6 pour expliquer le passage d'un mois à l'autre, d'abord pour les mois comptant moins de trente et un jours, puis pour les mois comptant trente et un jours.We will now describe the operation of the annual calendar with the help of Figures 1 to 6 to explain the transition from one month to another, first for months of less than thirty-one days, then for months with thirty-one days.

Les figures 1 à 3 illustrent le passage d'un mois à l'autre pour les mois de moins de trente et un jours. Le passage du 30 avril au 1er mai est pris en exemple.The Figures 1 to 3 illustrate the transition from one month to another for months of less than thirty-one days. The passage from April 30 to May 1 is taken as an example.

La figure 1 montre la situation de l'affichage le 30 avril à 23 heures 30. Le premier doigt 2 du mobile entraîneur de quantième 1 entre en contact avec la dent intérieure 10 du premier étage 3 de l'anneau du quantième 4. L'anneau indicateur de quantième 25 fait apparaître un chiffre 26 au travers du guichet 27 qui est le 30 (avril). Le disque indicateur des mois 16 fait apparaître le nom du mois d'avril pour une première fois 17 au travers du guichet 18. L'ergot 60 disposé à l'intérieur du second étage 9 de l'anneau de quantième 4 se trouve proche de la dent 52 de la roue 50 qui compose le renvoi 8.The figure 1 shows the situation of the display on April 30 at 11:30 pm. The first finger 2 of the date-driven mobile phone 1 comes into contact with the inner tooth 10 of the first stage 3 of the date ring 4. The indicator ring of date 25 shows a number 26 through the window 27 which is the 30 (April). The indicator disc of the months 16 shows the name of the month of April for the first time 17 through the window 18. The lug 60 disposed inside the second floor 9 of the date ring 4 is close to the tooth 52 of the wheel 50 which forms the reference 8.

La figure 2 montre la situation de l'affichage le 1er mai à 00h 30. Entraînés par le premier doigt 2 du mobile 1 l'anneau de quantième 4 et sa dent 10 ont progressé d'un pas. L'anneau indicateur 25 présente un court instant le chiffre 31 au travers du guichet 27. En même temps l'ergot 60 lié à l'anneau de quantième 4 a aussi progressé d'un pas entraînant la roue 50 par sa dent 52 dans le sens horaire. La roue 40, solidaire de la roue 50 pour former le renvoi 8, entraîne à son tour la roue annuelle 7 dans le sens antihoraire et par conséquent la planche 6 et l'ergot 20 qui lui est lié. A ce moment et faisant suite à la rotation du mobile 1, le second doigt 5 de ce dernier entre en contact avec l'ergot 20 de la planche 6. Lors de cette opération la roue annuelle 7 a progressé d'un vingt-quatrième de tour ainsi que le disque indicateur des mois 16 qui lui est lié. Le nom du mois d'avril apparaît ainsi une seconde fois 31, mais peu de temps, au travers du guichet 18.The figure 2 shows the position of the display 1 May to 00h 30. Driven by the first finger 2 of one mobile date ring 4 and its tooth 10 increased by one step. The indicator ring 25 has a short moment the number 31 through the window 27. At the same time the lug 60 connected to the date ring 4 has also progressed by one step driving the wheel 50 by its tooth 52 in the clockwise. The wheel 40, secured to the wheel 50 to form the return 8, in turn causes the annual wheel 7 in the counterclockwise direction and therefore the board 6 and the lug 20 which is connected thereto. At this time and following the rotation of the mobile 1, the second finger 5 of the latter comes into contact with the lug 20 of the board 6. During this operation the annual wheel 7 has progressed by one twenty-fourth of turn as well as the indicator disc of the months 16 which is bound to it. The name of the month of April appears a second time 31, but shortly, through the window 18.

La figure 3 montre la situation de l'affichage le 1er mai à 2 heures 00. Poursuivant sa rotation, le mobile 1 par son second doigt 5 a entraîné la planche 6 et son ergot 20 dans le sens antihoraire. Ainsi la roue annuelle 7, solidaire de la planche 6, de menée qu'elle était devient menante et entraîne à son tour le renvoi 8 dans le sens horaire et sa dent 53 fait progresser d'un pas l'anneau de quantième par sa dent 60. L'anneau indicateur 25 présente le chiffre 1 au travers du guichet 27. En tournant, la roue annuelle 7 a entraîné le disque indicateur des mois 16 qui affiche alors une première fois le mois de mai 32.The figure 3 shows the position of the display 1 May to 2 hours 00. Continuing its rotation, the moving body 1 by his second finger 5 has resulted in the plate 6 and its lug 20 in a counterclockwise direction. Thus the annual wheel 7, secured to the board 6, led it was becomes leading and in turn causes the reference 8 clockwise and its tooth 53 advances the date ring by its tooth 60. The indicator ring 25 has the number 1 through the window 27. Turning, the annual wheel 7 has driven the indicator disc months 16 which then displays a first time May 32.

On observera (voir figure 3) que les cinq ergots 20, 21, 22, 23 et 24 correspondent chacun aux mois de moins de trente et un jours, à savoir les mois d'avril, juin, septembre, novembre et février. On s'arrange pour que chacun de ces ergots se trouve sur le chemin du doigt 5 du mobile 1 à la fin des mois qui viennent d'être cités. Pour cela les ergots 20 à 24 sont placés nécessairement autour de la planche 6 à 60°, 90°, 60°, 90° et 60°. On observera ainsi qu'à la fin du mois de février, une correction manuelle reste nécessaire. Enfin, on remarquera que le mobile entraîneur du quantième 1 peut être du type à passage semi-instantané auquel cas un sautoir (non-représenté) doit être disposé sur la denture intérieure de l'anneau de quantième.We will observe (see figure 3 ) that the five pins 20, 21, 22, 23 and 24 each correspond to months of less than thirty-one days, namely the months of April, June, September, November and February. It is arranged that each of these lugs is on the path of the finger 5 of the mobile 1 at the end of the months just mentioned. For this purpose the lugs 20 to 24 are necessarily placed around the board 6 at 60 °, 90 °, 60 °, 90 ° and 60 °. We will observe that at the end of February, a manual correction is still necessary. Finally, it will be noted that the mobile trainer of the date 1 may be of the semi-instantaneous transit type in which case a jumper (not shown) must be placed on the internal toothing of the date ring.

Les figures 4 à 6 illustrent le passage d'un mois à l'autre pour les mois de trente et un jours. Le passage du 30 mai au 1er juin est pris en exemple.The Figures 4 to 6 illustrate the passage from one month to another for the months of thirty-one days. The transition from May 30 to June 1 is taken as an example.

La figure 4 montre la situation de l'affichage le 30 mai à 23 heures 30. Le doigt 2 du mobile entraîneur 1 entre en contact avec la dent intérieure 10 de l'anneau de quantième 4. L'indicateur de quantième 25 fait apparaître un chiffre 26 au travers du guichet 27 qui est le 30 (mai). Le disque indicateur des mois 16 fait apparaître le nom du mois de mai pour un première fois 17 au travers du guichet 18. L'ergot 60 de l'anneau de quantième 4 se trouve proche de la dent 52 de la roue 50 qui compose le renvoi 8. Si l'on observe la position angulaire de l'ergot 20 de la planche 6, on constate que la roue annuelle est restée à la place qu'elle avait le 1er mai à 2 heures 00 (voir figure 3).The figure 4 shows the situation of the display on May 30 at 11:30 pm. The finger 2 of the mobile driver 1 comes into contact with the inner tooth 10 of the date ring 4. The date indicator 25 shows a numeral 26 at through wicket 27 which is the 30th (May). The indicator disc of the months 16 shows the name of the month of May for the first time 17 through the window 18. The lug 60 of the date ring 4 is close to the tooth 52 of the wheel 50 which forms the reference 8. If one observes the angular position of the lug 20 of the board 6, it is found that the annual wheel has remained at the position it had on May 1 to 2:00 (see figure 3 ).

La figure 5 montre la situation de l'affichage le 31 mai à 23 heures 30. Entraîné par le doigt 2 du mobile 1, l'anneau de quantième 4 et sa dent 10 ont progressé d'un pas. L'anneau indicateur de quantième 25 présente le chiffre 31 au travers du guichet 27 et, à 23 heures 30 du 31 mai, le doigt 2 du mobile 1 entre en contact avec la dent intérieure 11 de l'anneau de quantième 4. En passant du 30 au 31 mai, l'ergot 60 lié à l'anneau de quantième a aussi progressé d'un pas entraînant la roue 50 par sa dent 52 dans le sens horaire. La roue 40, solidaire de la roue 50 pour former le renvoi 8 entraîne à son tour la roue annuelle 7 dans le sens antihoraire et par conséquent dans le même sens la planche 6 et l'ergot 20 qui lui est lié. Lors de cette opération, la roue annuelle 7 a progressé d'un vingt-quatrième de tour ainsi que le disque indicateur des mois 16 qui lui est lié. Le nom du mois de mai apparaît ainsi une seconde fois 32, mais peu de temps, au travers du guichet 18.The figure 5 shows the situation of the display on May 31 at 23:30. Driven by the finger 2 of the mobile 1, the date ring 4 and its tooth 10 have progressed by one step. The date indicator ring 25 has the number 31 through the window 27 and, at 23:30 on May 31, the finger 2 of the mobile 1 comes into contact with the inner tooth 11 of the date ring 4. By the way from 30 to 31 May, the lug 60 linked to the date ring has also progressed by one step driving the wheel 50 by its tooth 52 in the clockwise direction. The wheel 40, secured to the wheel 50 to form the return 8 in turn causes the annual wheel 7 in the counterclockwise direction and therefore in the same direction the board 6 and the lug 20 which is related thereto. During this operation, the annual wheel 7 has progressed one twenty-fourth of a turn as well as the indicator disk of the months 16 which is linked to it. The name of the month of May appears a second time 32, but shortly, through the window 18.

La figure 6 montre la situation de l'affichage le 1er juin à 0 heure 30. En poursuivant sa rotation le mobile 1 par son premier doigt 2 a entraîné l'anneau de quantième 4 d'un pas. Le chiffre 1 du 1er juin de l'indicateur de quantième 25 apparaît au travers du guichet 27. En même temps, l'ergot 60 de l'anneau de quantième a entraîné la roue 50 dans le sens horaire par sa dent 52. La roue 40 formant le renvoi 8 avec la roue 50 entraîne la roue annuelle 7 d'un pas et dans un sens antihoraire. Le disque indicateur des mois 16 qui est lié à la roue annuelle progresse ainsi d'un pas et fait apparaître l'indication 33, soit juin, dans le guichet 18. On observera que la planche 6 a aussi progressé d'un pas et avec elle l'ergot 21, cet ergot se préparant ainsi à remplir sa fonction à la fin du mois de juin qui ne comporte que trente jours.The figure 6 shows the position of the display on June 1 at 0 hours 30. Continuing its rotation the moving body 1 by its first finger 2 has led to the date ring 4 by one step. The 1 1 June to 25 calendar indicator seen through the window 27. At the same time, the lug 60 of date ring caused the wheel 50 clockwise by his tooth 52. The wheel 40 forming the return 8 with the wheel 50 drives the annual wheel 7 one step and in a counterclockwise direction. The indicator disk of the months 16 which is linked to the annual wheel progresses thus one step and shows the indication 33, ie June, in the window 18. It will be observed that the board 6 has also progressed a step and with it ergot 21, this ergot thus preparing to perform its function at the end of June which has only thirty days.

On va décrire maintenant à l'aide des figures 9 à 16 un mécanisme de quantième annuel exécuté selon un second mode de réalisation de l'invention. Ce mécanisme met en oeuvre et dans leur totalité tous les éléments utilisés jusqu'ici et décrits ci-dessus pour réaliser le mécanisme de quantième exécuté selon le premier mode de réalisation de l'invention. On y a ajouté simplement deux éléments supplémentaires de façon à ne faire apparaître qu'une seule fois le nom du mois dans le guichet qui lui est destiné.We will now describe with the help of Figures 9 to 16 an annual calendar mechanism executed according to a second embodiment of the invention. This mechanism implements and in their entirety all the elements used hitherto and described above to achieve the date mechanism executed according to the first embodiment of the invention. There are simply two additional elements added so that the name of the month appears only once in the window intended for it.

Ainsi les figures 9 à 16 montrent que le renvoi 8 comporte une troisième roue 70 qui est fixée sur la deuxième roue 50 qui compose, avec la première roue 40, le renvoi 8. Par ailleurs la roue annuelle 7 est surmontée d'une étoile 80 montée en rotation libre sur ladite roue annuelle 7. L'étoile 80 comporte des branches 81 qui sont en prise avec des dents 71 que comprend la troisième roue 70. Le nombre de branches 81 et le nombre de dents 71 que comprennent respectivement l'étoile 80 et la troisième roue 70 sont arrangés de telle manière que l'étoile progresse d'un pas quand la troisième roue progresse de deux pas.So the Figures 9 to 16 show that the reference 8 comprises a third wheel 70 which is fixed on the second wheel 50 which composes, with the first wheel 40, the reference 8. Furthermore the annual wheel 7 is surmounted by a star 80 mounted in free rotation on said annual wheel 7. The star 80 has branches 81 which are engaged with teeth 71 which comprises the third wheel 70. The number of branches 81 and the number of teeth 71 that respectively comprise the star 80 and the third wheel 70 are arranged in such a way that the star progresses one step when the third wheel progresses two steps.

Corollairement à ce qui vient d'être dit, l'étoile 80 porte un disque indicateur des mois 90 sur lequel sont apposés les noms 91 des douze mois de l'année. Ces noms apparaissent une fois chaque mois et à tour de rôle au travers d'un guichet 100 découpé dans le cadran 28 que porte la pièce d'horlogerie. Le disque indicateur 90 comprend ainsi douze secteurs égaux.As a corollary to what has just been said, the star 80 carries an indicator disc of the 90's on which are affixed the names 91 of the twelve months of the year. These names appear once every month and in turn through a window 100 cut in the dial 28 worn by the timepiece. The indicator disc 90 thus comprises twelve equal sectors.

On va décrire maintenant, sans revenir sur tous les détails décrits à propos du premier mode de réalisation mais en insistant sur les éléments nouveaux et en s'aidant des figures 9 à 16, le fonctionnement du quantième annuel exécuté selon le second mode de réalisation de l'invention pour expliquer le passage d'un mois à l'autre.We will describe now, without going back on all the details described about the first embodiment but by insisting on the new elements and with the help of Figures 9 to 16 , the operation of the annual calendar performed according to the second embodiment of the invention to explain the transition from one month to another.

Les figures 9 à 11 illustrent le passage d'un mois à l'autre pour les mois de moins de trente et un jours, le passage du 30 avril au 1er mai étant pris en exemple.The Figures 9 to 11 illustrate the transition from one month to the next for the months of less than thirty one days, the passage from April 30 to May 1 being taken as an example.

La figure 9 montre la situation de l'affichage le 30 avril à 23 heures 30. Le mois d'avril 91 apposé sur le disque indicateur 90 apparaît au travers du guichet 100. Le doigt 2 du mobile 1 s'apprête à faire tourner l'anneau du quantième et avec lui l'ergot 60 qui va entraîner le renvoi 8 dans le sens horaire. La troisième roue 70 du renvoi 8 tourne donc dans le sens horaire. Les dents 71, 72 et 73 de la roue 70 sont marquées dans les figures par un petit cercle pour les reconnaître et les distinguer des dents 51 de la deuxième roue qui se trouve au -dessous de la troisième. Le calendrier affiche le 30.The figure 9 shows the situation of the display on April 30 at 11:30 pm. The month of April 91 affixed to the indicator disk 90 appears through the window 100. The finger 2 of the mobile 1 is about to turn the ring of the date and with him the lug 60 which will cause the return 8 in the clockwise direction. The third wheel 70 of the reference 8 thus rotates clockwise. The teeth 71, 72 and 73 of the wheel 70 are marked in the figures by a small circle to recognize them and to distinguish them from the teeth 51 of the second wheel which is below the third. The calendar shows 30.

La figure 10 montre la situation de l'affichage le 1er mai à 0 heure 30. En tournant, l'anneau de quantième affiche un court instant la date du 31. Son ergot 60 a fait tourner le renvoi 8. En passant de la position représentée en figure 9 à la position représentée en figure 10, la dent 72 de la troisième roue 70 n'a pas entraîné la branche 82 de l'étoile 80 et le disque des mois 90 qui est lié à cette étoile affiche toujours le mois d'avril.The figure 10 shows the situation of the display on May 1 at 0 hours 30. By rotating, the date ring briefly displayed the date of 31. Her 60 pin rotated referral 8. In moving from the position shown in figure 9 at the position represented in figure 10 , the tooth 72 of the third wheel 70 did not cause the branch 82 of the star 80 and the disc of the 90's that is related to this star always displays the month of April.

La figure 11 montre la situation de l'affichage le 1er mai à 2 heures 00. Le renvoi 8 entraîné par la roue annuelle 6 entraînée à son tour par le doigt 5 du mobile 1 fait progresser d'un pas l'anneau de quantième par son ergot 60. Le calendrier affiche le 1er mai. En tournant, la troisième roue 70 par sa dent 72 fait avancer d'un pas l'étoile 80 par sa dent 82. Le disque des mois 90 lié à l'étoile 80 avance aussi d'un pas et le mois de mai 92 apparaît au travers du guichet 100.The figure 11 shows the position of the display 1 May to 2 hours 00. The reference 8 driven by the annual wheel 6 in turn driven by the finger 5 of the moving body 1 advances by one step the date ring through its lug 60. The calendar shows May 1 st . By turning, the third wheel 70 by its tooth 72 advances a star 80 by its tooth 82. The disc 90 months linked to the star 80 also advances one step and the month of May 92 appears through the counter 100.

Les figures 12 à 14 illustrent le passage d'un mois à l'autre pour les mois de trente et un jours, le passage du 30 mai au 1er juin étant pris en exemple.The Figures 12 to 14 illustrate the transition from one month to another month for thirty-one days, passage of the May 30 to June 1 is taken as an example.

La figure 12 montre la situation de l'affichage le 30 mai à 23 heures 30. Le mois de mai 92 apposé sur le disque indicateur 90 apparaît au travers du guichet 100. Le doigt 2 du mobile 1 s'apprête à faire tourner l'anneau du quantième par sa dent 10. En tournant, l'anneau du quantième, par son ergot 60, va entraîner le renvoi 8 dans le sens horaire ainsi que la troisième roue 70 qui lui est liée. Le calendrier affiche la date du 30.The figure 12 shows the situation of the display on May 30 at 23:30. The month of May 92 affixed to the indicator disc 90 appears through the window 100. The finger 2 of the mobile 1 is about to rotate the ring of the date by its tooth 10. By turning, the date ring, with its lug 60, will cause the reference 8 in the clockwise direction and the third wheel 70 which is linked thereto. The calendar displays the date of the 30th.

La figure 13 montre la situation de l'affichage le 31 mai à 23 heures 30. L'anneau du quantième a avancé d'un pas et le calendrier affiche la date du 31. L'ergot 60 de l'anneau de quantième a fait tourner le renvoi 8. En passant de la position représentée en figure 12 à la position représentée en figure 13, la dent 72 de la troisième roue 70 n'a pas entraîné la branche 82 de l'étoile 80 et le disque des mois 90 qui est lié à cette étoile affiche toujours le mois de mai.The figure 13 shows the situation of the display on the 31st of May at 11.30 pm The date ring has moved forward one step and the calendar shows the date of the 31st. The lug 60 of the date ring has turned the reference 8. Moving from the represented position to figure 12 at the position represented in figure 13 , the tooth 72 of the third wheel 70 has not driven the branch 82 of the star 80 and the disc of the 90 months that is linked to this star always displays the month of May.

La figure 14 montre la situation de l'affichage le 1er juin à 0 heure 30. En poursuivant sa rotation le mobile 1 par son premier doigt 2 a entraîné l'anneau du quantième d'un pas. Le chiffre 1 du 1er juin de l'indicateur de quantième 25 apparaît au travers du guichet 27. L'ergot 60 a aussi progressé d'un pas entraînant le renvoi 8 dans le sens horaire. En tournant, la troisième roue 70 par sa dent 72 fait avancer d'un pas l'étoile 80 par sa dent 82. Le disque des mois 90 lié à l'étoile 80 avance aussi d'un pas et le mois de juin 93 apparaît au travers du guichet 100.The figure 14 shows the position of the display on June 1 at 0 hours 30. Continuing its rotation the moving body 1 by its first finger 2 has led to the calendar ring of a step. The 1 1 June 25 of the calendar indicator appears through aperture 27. The lug 60 also advanced a step involving the dismissal 8 clockwise. By turning, the third wheel 70 by its tooth 72 advances the star 80 by its tooth 82. The disc of the 90 months linked to the star 80 also advances one step and the month of June 93 appears through the counter 100.

Le second mode d'exécution de l'invention qui vient d'être décrit permet de proposer une lecture plus aisée du nom des mois. En effet, le disque des mois 90 ne comporte que douze secteurs, soit un secteur par mois ce qui permet d'agrandir notablement le nom du mois et d'augmenter ainsi sa lisibilité. Les figures 9 à 14 montrent bien cet avantage et surtout un graphisme harmonisé entre la date et le mois qui présente une taille très semblable. On comprendra que ceci ne peut pas être atteint si le disque des mois (figures 1 à 6) comporte vingt-quatre secteurs auquel cas le nom des mois doit être diminué en regard des chiffres affichant la date.The second embodiment of the invention which has just been described makes it possible to propose an easier reading of the name of the months. Indeed, the disc of the 90 months has only twelve sectors, one sector per month which allows to significantly increase the name of the month and increase its readability. The Figures 9 to 14 show this advantage and especially a harmonized graphic between the date and the month which has a very similar size. It will be understood that this can not be achieved if the disc of the months ( Figures 1 to 6 ) has twenty-four sectors, in which case the name of the months must be reduced next to the figures showing the date.

On mentionnera encore que le mécanisme de quantième annuel selon l'invention est très simple à fabriquer puisqu'il ne comporte que des roues classiques taillées régulièrement, les dents qu'elles portent étant uniformément réparties sur leur pourtour. On remarquera ainsi que le mécanisme en question peut très facilement remplacer un simple mécanisme de quantième ne comportant que la date et cela sans modification importante du calibre de base. C'est notamment le cas du calibre 2892 A2 mis sur le marché par ETA SA Manufacture Horlogère Suisse.It will also be mentioned that the annual calendar mechanism according to the invention is very simple to manufacture since it comprises only conventional wheels cut regularly, the teeth they wear being uniformly distributed around their periphery. It will be noted that the mechanism in question can very easily replace a simple date mechanism with only the date and without significant modification of the basic caliber. This is notably the case of the 2892 A2 caliber put on the market by ETA SA Manufacture Horlogère Suisse.
