Description

La présente invention a pour objet un mécanisme d'affichage pour pièce d'horlogerie et en particulier un mécanisme d'affichage du quantième.The subject of the present invention is a display mechanism for a timepiece and in particular a date display mechanism.

Une des difficultés rencontrées dans l'affichage du quantième pour une pièce d'horlogerie, et notamment une montre bracelet, est sa lisibilité. En effet, avec trente-et-une indications à répartir sur un mobile d'affichage (disque de quantième) ou directement sur le cadran (affichage avec aguille), la taille des indications est souvent très petite, voire trop petite pour être lues confortablement.One of the difficulties encountered in displaying the date for a timepiece, and in particular a wristwatch, is its readability. Indeed, with thirty-one indications to be distributed on a mobile display (date disc) or directly on the dial (display with hand), the size of the indications is often very small, even too small to be read comfortably. .

Plusieurs solutions à ce problème ont été envisagées ; soit des moyens d'agrandissement optiques, comme une loupe, sont prévus sur la glace pour faciliter la lecture du quantième, soit les chiffres des unités et des dizaines sont répartis sur des mobiles séparés et alors la taille de ces chiffres peut alors être considérablement agrandie.Several solutions to this problem have been considered; either optical magnification means, such as a magnifying glass, are provided on the crystal to facilitate reading of the date, or the units and tens digits are distributed on separate mobiles and then the size of these digits can then be considerably enlarged .

Les mécanismes de quantième appliquant cette dernière solution sont communément appelés « grande date » et sont bien connus. Le document CH 310559 décrit par exemple un affichage de quantième, dans lequel le quantième est indiqué par deux disques juxtaposés ou coplanaires, l'un portant les chiffres des dizaines, l'autre ceux des unités. D'autres agencements des disques des unités et des dizaines sont possibles. Les documents EP 0 529 191 et EP 1 070 996 décrivent un affichage de quantième avec un disque des unités et un disque des dizaines superposés. Les documents CH 690 515 , DE 102005010602 et CH 688 671 décrivent un affichage de quantième avec un disque des unités et un disque des dizaines coplanaires et coaxiaux.The date mechanisms applying this last solution are commonly called “big date” and are well known. The document CH 310559 describes for example a date display, in which the date is indicated by two juxtaposed or coplanar discs, one bearing the tens digits, the other those of the units. Other arrangements of the units and tens discs are possible. The documents EP 0 529 191 and EP 1 070 996 describe a date display with a units disc and a tens disc superimposed. The documents CH 690 515 , DE 102005010602 and CH 688 671 describe a date display with a units disc and a coplanar and coaxial tens disc.

La répartition des chiffres sur les disques des unités et des dizaines peut varier notamment en fonction de la disposition et de la taille des indications. Le disque des unités porte en général la série 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 qui peut être éventuellement répétée plusieurs fois. Le disque des dizaines porte généralement la série 0, 1, 2, 3 parfois répétée plusieurs fois comme dans le document CH 310559 dans lequel le disque des dizaines porte la série 0, 1, 2, 3, 0, 1, 2, 3.The distribution of the digits on the units and tens discs may vary in particular according to the layout and size of the indications. The units disk generally bears the series 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 which can possibly be repeated several times. The tens disc generally bears the series 0, 1, 2, 3 sometimes repeated several times as in the document CH 310559 in which the tens disc bears the series 0, 1, 2, 3, 0, 1, 2, 3.

Avec cette répartition, le mobile des dizaines entraîné par le mobile de quantième sera commandé quatre fois par mois avec deux changements très proches : du 29 au 30 et du 31 au 01 tandis que le mobile des unités est lui commandé tous les jours, sauf du 31 au 01 où le chiffre 1 reste deux jours de suite.With this distribution, the tens wheel driven by the date wheel will be ordered four times a month with two very similar changes: from 29 to 30 and from 31 to 01, while the units wheel is ordered every day, except from 31 to 01 where the number 1 remains two days in a row.

En général, le changement de dizaine est commandé par une roue de trente-et-une dents dont on n'a gardé que quatre dents (pour les indications des dizaines 0, 1, 2, 3). Dans ce cas, il faut prévoir un système de verrouillage pour les vingt-sept jours où le mobile des dizaines n'avance pas, ainsi qu'un système pour éviter la désindexation du mécanisme en cas de choc et empêcher le mobile des dizaines de tourner lorsqu'il est en face d'un secteur sans dent.In general, the change of ten is controlled by a wheel of thirty-one teeth of which only four teeth have been kept (for the indications of the tens 0, 1, 2, 3). In this case, a locking system must be provided for the twenty-seven days when the tens mobile does not move forward, as well as a system to prevent the mechanism from being de-indexed in the event of an impact and to prevent the tens mobile from rotating. when it is in front of a toothless sector.

Selon d'autres répartitions, le disque des dizaines porte la série de chiffres : 0, 0, 0, 0, 1, 1, 2, 2, 3, 3 ou une autre série formée de répétitions des chiffres 0, 1, 2 et 3 pour obtenir dix caractères soit le même nombre que pour la série 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 des unités. Même avec de telles répartitions, il existe des jours où le mobile des dizaines va rester immobileAccording to other distributions, the tens disk bears the series of digits: 0, 0, 0, 0, 1, 1, 2, 2, 3, 3 or another series made up of repetitions of the digits 0, 1, 2 and 3 to obtain ten characters is the same number as for the series 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 of the units. Even with such distributions, there are days when the mobile of the tens will stand still.

Un autre problème important arrive lors du passage du 31 au 01, le chiffre 1 des disques des unités devant rester en place deux jours de suite, tandis que le disque des dizaines avance. La solution la plus couramment utilisée consiste à enlever une dent à l'étoile de 31 commandant le mécanisme de quantième et dont la vitesse est d'un tour en trente-et-un jours. Ainsi, au passage du 31 au 01, ladite étoile de 31 n'entraînera pas le mobile des unités qui affichera le chiffre 1 deux jours de suite. Comme précédemment pour le mobile des dizaines, il faut également s'assurer que le mobile des unités, en face d'un secteur sans dent, ne se désindexe pas en cas de choc.Another important problem occurs during the transition from 31 to 01, the number 1 of the discs of the units having to remain in place for two days in a row, while the disc of the tens advances. The solution most commonly used consists in removing a tooth from the star of 31 controlling the date mechanism and whose speed is one revolution in thirty-one days. Thus, when passing from 31 to 01, said star of 31 will not cause the mobile unit to display the number 1 two days in a row. As previously for the tens mobile, it must also be ensured that the units mobile, facing a toothless sector, does not de-index in the event of an impact.

Le but de la présente invention est de proposer un mécanisme d'affichage du quantième dans lequel les chiffres des unités et des dizaines sont répartis sur des mobiles séparés (affichage type « grande date ») et qui offre une solution simple pour le passage du 31 au 01 ainsi qu'un verrouillage sûr du mécanisme en cas de choc, empêchant le désindexage de l'un ou l'autre des mobiles des unités ou des dizaines.The object of the present invention is to propose a date display mechanism in which the units and tens digits are distributed over separate mobiles (“big date” type display) and which offers a simple solution for switching from 31 to 01 as well as a safe locking of the mechanism in the event of an impact, preventing the de-indexing of one or other of the mobiles units or tens.

La présente invention a pour objet un mécanisme d'affichage du quantième destiné à équiper un mouvement d'une pièce d'horlogerie.The subject of the present invention is a date display mechanism intended to be fitted to a movement of a timepiece.

En particulier, le mécanisme d'affichage du quantième illustré comprend un indicateur des dizaines 11 et un indicateur des unités 12, formant ensemble un affichage du quantième.In particular, the illustrated date display mechanism comprises a tens indicator 11 and a units indicator 12, together forming a date display.

L'indicateur des dizaines 11 a la forme d'une couronne et porte la série de chiffres 0, 1, 2, 3 répétée cinq fois dans le sens antihoraire. L'indicateur des dizaines 11 est porté par une bague des dizaines 110 qui présente une denture extérieure 111 et une denture de positionnement 112 coopérant avec un sautoir 113 pour son positionnement angulaire.The tens indicator 11 has the shape of a crown and bears the series of numbers 0, 1, 2, 3 repeated five times counterclockwise. The tens indicator 11 is carried by a tens ring 110 which has a toothing outer 111 and a positioning toothing 112 cooperating with a jumper 113 for its angular positioning.

L'indicateur des unités 12 a également la forme d'une couronne et porte la série de chiffres 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, répétée deux fois dans le sens antihoraire. L'indicateur des unités 12 est porté par une bague des unités 120 comprenant une denture extérieure 121 une denture de positionnement 122 coopérant avec un sautoir 123 pour son positionnement angulaire.The 12 units indicator also has the shape of a crown and bears the series of numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, repeated twice counterclockwise. The units indicator 12 is carried by a units ring 120 comprising an external toothing 121 a positioning toothing 122 cooperating with a jumper 123 for its angular positioning.

Les unités et les dizaines étant indiquées par des mobiles séparés, l'affichage du quantième est du type « grande date » et permet donc d'utiliser des indications de taille raisonnable pour faciliter la lecture.The units and tens being indicated by separate mobiles, the date display is of the “large date” type and therefore allows the use of reasonably sized indications to facilitate reading.

Dans la forme d'exécution illustrée, l'indicateur des dizaines 11 et l'indicateur des unités 12 sont coplanaires et juxtaposés.In the illustrated embodiment, the tens indicator 11 and the units indicator 12 are coplanar and juxtaposed.

De manière générale, le mécanisme de quantième selon la présente forme d'exécution est agencé pour entraîner la bague des unités 120 (indicateur des unités 12) trente fois par mois, la bague des dizaines 110 et l'indicateur des dizaines 11 quatre fois par mois.In general, the date mechanism according to the present embodiment is arranged to drive the units ring 120 (units indicator 12) thirty times per month, the tens ring 110 and the tens indicator 11 four times per month. month.

Dans la forme d'exécution illustrée, le mécanisme de quantième comprend un mobile de quantième 5 agencé pour être relié cinématiquement au mouvement de la pièce d'horlogerie comprenant le mécanisme de quantième. Le mobile de quantième 5 est monobloc mais comprend deux étages avec deux dentures différentes. Pour faciliter la compréhension, ces deux dentures seront appelées dans la suite première roue de quantième 51 et seconde roue de quantième 52.In the illustrated embodiment, the date mechanism includes a date mobile 5 arranged to be kinematically connected to the movement of the timepiece comprising the date mechanism. The date wheel set 5 is in one piece but comprises two stages with two different toothings. To facilitate understanding, these two toothings will be referred to below as first date wheel 51 and second date wheel 52.

La première roue de quantième 51 comprend trente-et-une dents et est soumise à l'action d'un sautoir 511 pour son positionnement. Le sautoir 511 assure ainsi le positionnement angulaire de l'ensemble du mobile de quantième 5. C'est par cette première roue de quantième 51 que le mobile de quantième 5 est relié cinématiquement au mouvement de la pièce d'horlogerie pour son entraînement d'un pas par jour (dans le sens horaire dans les figures). Cette liaison cinématique est bien connue et ne sera pas décrite en détail dans la suite.The first date wheel 51 comprises thirty-one teeth and is subjected to the action of a jumper 511 for its positioning. The jumper 511 thus ensures the angular positioning of the whole of the date wheel set 5. It is via this first date wheel 51 that the date wheel set 5 is kinematically connected to the movement of the timepiece for its drive of one step per day (clockwise in the figures). This kinematic connection is well known and will not be described in detail below.

La première roue de quantième 51 est reliée cinématiquement à la bague des dizaines 110 et à l'indicateur des dizaines 11 pour son entraînement. Dans la forme d'exécution illustrée (voir figures 4a et 4b), la première roue de quantième 51 coopère avec un renvoi des dizaines 60. Ce renvoi des dizaines 60 entraîne une roue entraîneuse des dizaines 61 solidaire d'une roue des dizaines 62 comprenant quatre dents, dont la répartition correspond au changement de dizaines dans un mois complet de trente-et-un jours (passage de la dizaine 0 à 1 après neuf jours, 1 à 2 après dix jours, 2 à 3 après dix jours et 3 à 0 après 1 jour). La roue des dizaines 62 engrène avec le pignon des dizaines 63 qui comprend lui aussi quatre dents. Une roue intermédiaire des dizaines 64 est coaxiale et solidaire du pignon des dizaines 63 et engrène avec la denture extérieure 111 de la bague des dizaines 110 portant l'indicateur des dizaines 11.The first date wheel 51 is kinematically connected to the tens ring 110 and to the tens indicator 11 for its drive. In the illustrated embodiment (see figure 4a and 4b ), the first date wheel 51 cooperates with a tens wheel 60. This tens wheel 60 drives a driving tens wheel 61 integral with a tens wheel 62 comprising four teeth, the distribution of which corresponds to the change of tens in a complete month of thirty-one days (transition from ten 0 to 1 after nine days, 1 to 2 after ten days, 2 to 3 after ten days and 3 to 0 after 1 day). The tens wheel 62 meshes with the tens pinion 63 which also comprises four teeth. An intermediate tens wheel 64 is coaxial with and integral with the tens pinion 63 and meshes with the external toothing 111 of the tens ring 110 carrying the tens indicator 11.

La seconde roue de quantième 52 est reliée cinématiquement à la bague des unités 120 et à l'indicateur des unités 12 pour son entraînement. Dans la forme d'exécution illustrée (voir figures 5a et 5b), la seconde roue de quantième 52 engrène avec une roue entraîneuse des unités 7 solidaire d'une planche entraîneuse des unités 71. La planche entraîneuse des unités 71 engrène avec un mobile de blocage 8, lui-même en prise avec un pignon des unités 72 comprenant quatre dents. Le pignon des unités 72 est solidaire et coaxial d'une roue intermédiaire des unités 73 en prise avec une denture 121 de la bague des unités 120.The second date wheel 52 is kinematically connected to the units ring 120 and to the units indicator 12 for its drive. In the illustrated embodiment (see figure 5a and 5b ), the second date wheel 52 meshes with a unit drive wheel 7 secured to a unit drive plate 71. The unit drive plate 71 meshes with a blocking mobile 8, itself engaged with a unit pinion 72 comprising four teeth. The pinion of the units 72 is secured and coaxial with an intermediate wheel of the units 73 meshing with a toothing 121 of the ring of the units 120.

Le fonctionnement du mécanisme d'affichage illustré aux figures est décrit ci-dessous.The operation of the display mechanism illustrated in the figures is described below.

Une fois par jour (aux environs de minuit), le mobile de quantième 5, entraîné par le mouvement de la pièce d'horlogerie, pivote d'un pas (1/31ème de tour) dans le sens horaire (un pas pour un quantième simple, au moins un pas pour un quantième annuel, perpétuel ou séculaire). Il entraine alors via les chaines cinématiques décrites ci-dessus l'indicateur des unités 12 (via la seconde roue de quantième 52 et la roue entraîneuse des unités 7 notamment) et/ou l'indicateur des dizaines 11 (via la première roue de quantième 51 et la roue entraîneuse des dizaines 61 notamment).Once a day (around midnight), the date mobile 5, driven by the movement of the timepiece, pivots by one step (1/31 th of a turn) clockwise (one step for one simple calendar, at least one step for an annual, perpetual or secular calendar). It then drives via the kinematic chains described above the units indicator 12 (via the second date wheel 52 and the units driving wheel 7 in particular) and/or the indicator tens 11 (via the first date wheel 51 and the tens driving wheel 61 in particular).

Le cas particulier du passage du 31 ou 01 en fin de mois, objet de la présente invention, est décrit ci-après. Lors du passage du 31 au 01 en fin de mois, l'indicateur des dizaines 11 tourne d'un pas (pour passer de 3 à 0) tandis que l'indicateur des unités 12 doit rester immobile (pour continuer à afficher le chiffre 1). Pour ce faire, la seconde roue de quantième 52 et la roue entraîneuse des unités 7 sont agencées pour que, une fois par mois, au passage du 31 au 01, le mobile de quantième 5 n'entraîne pas la roue entraîneuse des unités 7. Ainsi, lorsque le mobile de quantième 5 effectue un tour, la roue entraîneuse des unités 7 effectue un tour également, mais le mobile de quantième 5 a effectué trente-et-un pas, tandis que la roue entraîneuse des unités 7 aura effectué trente pas et un arrêt. Plusieurs agencements connus sont envisageables pour le mobile de quantième 5 et la roue entraîneuse des unités 7. La solution proposée par la présente invention est décrite ci-après en référence notamment aux figures 3a à 3g.The particular case of the passage of 31 or 01 at the end of the month, object of the present invention, is described below. When changing from 31 to 01 at the end of the month, the tens indicator 11 rotates one step (to go from 3 to 0) while the units indicator 12 must remain stationary (to continue to display the number 1 ). To do this, the second date wheel 52 and the unit driving wheel 7 are arranged so that, once a month, when changing from 31 to 01, the date mobile 5 does not drive the unit driving wheel 7. Thus, when the date wheel set 5 performs a revolution, the drive wheel of the units 7 also performs a turn, but the wheel set of the date 5 has taken thirty-one steps, while the drive wheel of the units 7 will have taken thirty steps. and a stop. Several known arrangements can be envisaged for the date wheel set 5 and the drive wheel of the units 7. The solution proposed by the present invention is described below with particular reference to the figures 3a to 3g .

Selon l'invention, la seconde roue de quantième 52 du mobile de quantième 5 comprend vingt-neuf dents taillées sur un profil de trente-et-une dents et deux secteurs sans dent 521, 522 occupant la place d'une dent, le tout étant réparti comme suit : un secteur denté 520 de vingt-huit dents consécutives, suivi d'un secteur sans dent 521, d'une dent 523 et du deuxième secteur sans dent 522. La roue entraîneuse des unités 7 comprend vingt-huit dents taillées sur un profil de trente dents et deux secteurs sans dent 701, 702 occupant la place d'une dent, le tout étant réparti comme suit : un secteur denté 700 de vingt-sept dents consécutives, suivi d'un secteur sans dent 701, d'une dent seule 703 et du deuxième secteur sans dent 702.According to the invention, the second date wheel 52 of the date wheel set 5 comprises twenty-nine teeth cut on a profile of thirty-one teeth and two toothless sectors 521, 522 occupying the place of a tooth, the whole being distributed as follows: a toothed sector 520 of twenty-eight consecutive teeth, followed by a toothless sector 521, a tooth 523 and the second toothless sector 522. The driving wheel of the units 7 comprises twenty-eight cut teeth on a profile of thirty teeth and two toothless sectors 701, 702 occupying the place of one tooth, the whole being distributed as follows: a toothed sector 700 of twenty-seven consecutive teeth, followed by a toothless sector 701, d a single tooth 703 and the second sector without a tooth 702.

Les figures 3a et 3b illustrent le positionnement de la seconde roue de quantième 52 et de la roue entraîneuse des unités 7 le 29, respectivement le 30 du mois. A partir de la position de la figure 3b, lors du prochain pas du mobile de quantième 5, une dent 5201 du secteur denté 520 de la seconde roue de quantième 52 va engrener avec la dent 704 du secteur denté 700 de la roue entraîneuse des unités 7 immédiatement adjacente au premier secteur sans dent 701 mais non adjacente au second secteur sans dent 702. La roue entraîneuse des unités 7 pivote elle aussi d'un pas et la date affichée désormais est le 31. Cette position est illustrée à la figure 3c.The figures 3a and 3b illustrate the positioning of the second date wheel 52 and of the drive wheel of the units 7 on the 29th, respectively the 30th of the month. From the position of the figure 3b , during the next step of the mobile from date 5, a tooth 5201 of the toothed sector 520 of the second date wheel 52 will mesh with the tooth 704 of the toothed sector 700 of the unit driving wheel 7 immediately adjacent to the first sector without tooth 701 but not adjacent to the second sector without tooth 702. The driving wheel of units 7 also rotates one step and the date displayed is now 31. This position is illustrated in figure 3c .

Au prochain pas du mobile de quantième 5, un secteur sans dent 521 de la seconde roue de quantième 52 coopère avec le premier secteur sans dent 701 de la roue entraîneuse de quantième 7, qui n'est donc pas entraînée et marque un arrêt. Ainsi, l'indicateur des unités 12 reste immobile. L'indicateur des dizaines 11 a, quant à lui, pivoté, entraîné par le mobile de quantième 5 (plus précisément par la première roue de quantième 51). La date affichée est le 01. La figure 3d illustre la position de la seconde roue de quantième 52 et de la roue entraîneuse des unités 7 dans ce cas.At the next step of the date mobile 5, a toothless sector 521 of the second date wheel 52 cooperates with the first toothless sector 701 of the date driving wheel 7, which is therefore not driven and marks a stop. Thus, the units indicator 12 remains stationary. The tens indicator 11 has, for its part, pivoted, driven by the date wheel set 5 (more precisely by the first date wheel 51). The date displayed is 01. The 3d figure illustrates the position of the second date wheel 52 and of the units driving wheel 7 in this case.

De préférence, et comme illustré aux figures, la dent 704 du secteur denté 700 de la roue entraîneuse des unités 7 immédiatement adjacente au premier secteur sans dent 701 mais non adjacente au second secteur sans dent 702 est légèrement tronquée pour permettre à la seconde roue de quantième 52 de pivoter sans entraîner la roue entraîneuse des unités 7 et à l'une des dents du secteur denté 520 de la seconde roue de quantième 52 de pouvoir sortir du premier secteur sans dent 701 de la roue entraîneuse des unités 7 sans entraîner cette dernière.Preferably, and as illustrated in the figures, the tooth 704 of the toothed sector 700 of the driving wheel of the units 7 immediately adjacent to the first sector without tooth 701 but not adjacent to the second sector without tooth 702 is slightly truncated to allow the second wheel to date 52 to pivot without driving the unit drive wheel 7 and one of the teeth of the toothed sector 520 of the second date wheel 52 to be able to leave the first toothless sector 701 of the unit drive wheel 7 without driving the latter .

Au prochain pas de la seconde roue de quantième 52, la dent 523 de cette roue située entre les secteurs sans dent 521, 522 coopère avec la dent 703 de la roue entraîneuse des unités 7 située entre les secteurs sans dent 701, 702. La roue entraîneuse des unités 7 pivote à nouveau d'un pas entraînant l'indicateur des unités 12. La date affichée est le 02. La figure 3f illustre la position de la seconde roue de quantième 52 et de la roue entraîneuse des unités 7 dans ce cas.At the next step of the second date wheel 52, the tooth 523 of this wheel located between the toothless sectors 521, 522 cooperates with the tooth 703 of the drive wheel of the units 7 located between the toothless sectors 701, 702. 7 units trainer pivots again one step driving the 12 units indicator. The date displayed is 02. The figure 3f illustrates the position of the second date wheel 52 and of the units driving wheel 7 in this case.

Les figures 3g et 3h illustrent les deux pas suivants de la seconde roue de quantième 52, lorsque les dents de son secteur denté 520 coopèrent à nouveau de manière classique avec les dents du secteur denté 700 de la roue entraîneuse des unités 7 (retour à un engrènement normal pour l'affichage du 03 à la figure 3g et 04 à la figure 3h).The figure 3g and 3h illustrate the next two steps of the second date wheel 52, when the teeth of its toothed sector 520 again cooperate in a conventional manner with the teeth of the toothed sector 700 of the drive wheel of the units 7 (return to normal meshing for the display from 03 to figure 3g and 04 at the figure 3h ).

De préférence, le second secteur sans dent 702 de la roue entraîneuse des unités 7 comprend un plat 706 reliant ledit second secteur sans dent 702 à la dent 705 du secteur denté 700 qui lui est immédiatement adjacente. Ce plat 706 est conformé pour empêcher la roue entraîneuse des unités 7 d'entraîner la seconde roue de quantième 52 le premier du mois (01 affiché), en cas de choc ou d'inertie en aval par exemple. Ainsi, le 31 et le premier du mois, si un choc ou une inertie en aval vient à mettre en rotation la roue entraîneuse des unités 7, le plat 706 vient buter contre la dent 523 de la seconde roue de quantième 52 située entre les deux secteurs sans dents 521, 522 (la figure 3e illustre cette situation pour le premier du mois, 01).Preferably, the second toothless sector 702 of the drive wheel of the units 7 comprises a flat 706 connecting said second toothless sector 702 to the tooth 705 of the toothed sector 700 which is immediately adjacent to it. This flat 706 is shaped to prevent the drive wheel of the units 7 from driving the second date wheel 52 on the first of the month (01 displayed), in the event of impact or inertia downstream for example. Thus, on the 31st and the first of the month, if a shock or inertia downstream causes the drive wheel of the units 7 to rotate, the flat 706 comes to abut against the tooth 523 of the second date wheel 52 located between the two sectors without teeth 521, 522 (the figure 3e illustrates this situation for the first of the month, 01).

L'enchaînement ci-dessus, décrit étape par étape, pour le passage du 31 au 01 à lieu quelle que soit la durée du mois : c'est-à-dire qu'il a lieu pour les mois de trente-et-un jours mais également pour les mois de trente jours (le passage du 30 au 01 est en fait le passage du 30 au 31 puis le passage du 31 au 01, le tout en accéléré) et les mois de 28 ou 29 jours (passage en accéléré du 28 au 29, du 29 au 30, du 30 au 31 et du 31 au 01).The sequence above, described step by step, for the passage from 31 to 01 takes place whatever the length of the month: that is to say that it takes place for the months of thirty-one days but also for the months of thirty days (the passage from 30 to 01 is in fact the passage from 30 to 31 then the passage from 31 to 01, all accelerated) and the months of 28 or 29 days (transition in accelerated from 28 to 29, from 29 to 30, from 30 to 31 and from 31 to 01).

Ainsi, il est donc possible de gérer le passage du 31 au 01 de manière très simple. Le système de la présente forme d'exécution est également sûr, puisque il n'y a pas de risque de désindexation entre la seconde roue de quantième 52 et la roue entraîneuse des unités 7, si cette dernière devenait motrice en cas de choc suffisant pour mettre en rotation l'indicateur des unités 12 par exemple : en effet, pas de désindexation possible lorsque les secteurs dentés 520 et 700 engrènent normalement (entre le 2 et le 30 de chaque mois) et pas de désindexation possible le 31 ou le premier du mois, grâce à la forme du second secteur sans dent 702 de la roue entraîneuse des unités et à son plat 706.Thus, it is therefore possible to manage the transition from 31 to 01 in a very simple way. The system of the present embodiment is also safe, since there is no risk of de-indexation between the second date wheel 52 and the driving wheel of the units 7, if the latter became driving in the event of an impact sufficient to rotate the indicator of units 12 for example: indeed, no de-indexation possible when the toothed sectors 520 and 700 mesh normally (between the 2nd and the 30th of each month) and no de-indexation possible on the 31st or the first of the month, thanks to the shape of the second toothless sector 702 of the drive wheel of the units and its flat 706.

Le mécanisme d'affichage du quantième décrit ci-dessus peut encore comprendre un mécanisme de correction pour permettre de corriger le quantième.The date display mechanism described above may also include a correction mechanism to enable the date to be corrected.

Le mécanisme d'affichage décrit ci-dessus permettant l'affichage du quantième est un exemple d'une forme d'exécution d'un mécanisme d'affichage du quantième selon l'invention. En variante, le mécanisme d'affichage du quantième selon l'invention pourrait être un quantième simple, annuel, perpétuel ou séculaire et permettre en outre l'affichage du jour de la semaine et du mois.The display mechanism described above allowing the display of the date is an example of an embodiment of a date display mechanism according to the invention. As a variant, the calendar display mechanism according to the invention could be a simple, annual, perpetual or secular calendar and also allow the display of the day of the week and of the month.

De manière générale, le mécanisme d'affichage du quantième selon l'invention comprend un indicateur des unités, un indicateur des dizaines et un mobile de quantième relié à l'indicateur des unités et à l'indicateur des dizaines pour leur entraînement, la chaîne cinématique reliant le mobile de quantième à l'indicateur des unités comprenant un premier mobile et un second mobile, le première mobile étant agencé pour engrener avec le second mobile. Selon l'invention, le premier mobile comprend vingt-neuf dents taillées sur un profil de trente-et-une dents ainsi qu'un premier et un second secteurs sans dent occupant chacun la place d'une dent, les premier et second secteurs sans dent du premier mobile étant non adjacents et séparés par une dent. Le second mobile comprend vingt-huit dents taillées sur un profil de trente dents ainsi qu'un premier et un second secteurs sans dent occupant chacun la place d'une dent, les premier et second secteurs sans dent du second mobile étant non adjacents et séparés par une dent.In general, the date display mechanism according to the invention comprises a units indicator, a tens indicator and a date mobile connected to the units indicator and to the tens indicator for their drive, the chain kinematics connecting the date mobile to the unit indicator comprising a first mobile and a second mobile, the first mobile being arranged to mesh with the second mobile. According to the invention, the first mobile comprises twenty-nine teeth cut on a profile of thirty-one teeth as well as a first and a second sectors without teeth each occupying the place of a tooth, the first and second sectors without tooth of the first mobile being non-adjacent and separated by a tooth. The second mobile comprises twenty-eight teeth cut on a profile of thirty teeth as well as a first and a second toothless sectors each occupying the place of a tooth, the first and second toothless sectors of the second mobile being non-adjacent and separated by a tooth.

Le premier mobile est agencé pour engrener avec le second mobile de sorte que lorsque le premier mobile fait un tour, il effectue trente-et-un pas et entraîne le second mobile d'un tour également mais celui-ci n'aura effectué que trente pas et un arrêt.The first mobile is arranged to mesh with the second mobile so that when the first mobile makes a turn, it performs thirty-one steps and also drives the second mobile one turn, but the latter will have only completed thirty step and a stop.

Il est ainsi possible de gérer le passage du 31 au 01 avec un quantième du type grande date, de manière très simple et peu encombrante.It is thus possible to manage the transition from 31 to 01 with a calendar of the large date type, in a very simple and space-saving manner.

De préférence, le second secteur sans dent du second mobile est conformé pour empêcher toute désindexation des premier et second mobile lorsque ledit premier mobile engrène avec ledit second secteur sans dent du second mobile. De cette façon, le mécanisme est sécurisé en cas de choc ou d'inertie en aval.Preferably, the second toothless sector of the second mobile is shaped to prevent any de-indexing of the first and second mobile when said first mobile meshes with said second toothless sector of the second mobile. In this way, the mechanism is secure in the event of shock or inertia downstream.
