- an angle formed by a half-line originating from the axis A1 of rotation of the control mobile and passing through the axis A3 of rotation of the first mobile and by a half-line having origin the axis A1 of rotation of the control wheel and passing through the axis A4 of rotation of the second wheel is advantageously less than 170 °, or even less than 160 °.
- This arrangement makes it possible to coexist the disks of the tens and units in the same plane closely, while displaying substantially enlarged fonts in comparison with those conventionally displayed by a conventional date disc. Such a conformation is possible by the fact that a digit or digit is split on the tens disk, for example the digit or digit "1".
- an angle ⁇ formed by a half-line, originating from the axis of rotation A1 of the control wheel 1 and passing through the vacuum 98 induced by the absence of a tooth, and the half-line, originating in the axis of rotation of the control wheel 1 and passing through the axis of symmetry of the tooth provided to allow the drive of the tens disk from the twenty-ninth calendar to the thirtieth day, may be equal to or substantially equal to the angle ⁇ .
- the digit or digit "1" is preferentially split on the tens disk.
- the digits "0", “2", “3” could be split by changing the distribution of the teeth of the fourth toothing 1b.

Ce mobile de commande a par ailleurs pour avantage de minimiser l'épaisseur requise pour la réalisation d'un tel dispositif.Preferably, the invention relates to a device for displaying an hourly or time-derived indication, in particular a device for displaying a "big date" indication in which the indication is displayed by first and second disks provided for displaying respectively the tens and the units of the indication. It is proposed to implement a simplified control mobile disk tens and units. The control mobile is arranged and shaped so as to rationalize the construction of the device. This also makes it possible to simplify and streamline the construction of the watch movement in which it is intended to be integrated. This control mobile also has the advantage of minimizing the thickness required for the production of such a device.
Un premier mode de réalisation d'une pièce d'horlogerie 120 selon l'invention est décrit ci-après en référence aux
Le dispositif d'affichage de quantième 100 comprend :
- un
premier mobile 3 incluant unepremière denture 31 et un disque d'unités 32 portant deschiffres 33 destinés à indiquer les unités de quantième, - un
deuxième mobile 4 incluant unedeuxième denture 41 et un deuxième disque dedizaines 42 portant deschiffres 43 destinés à indiquer les dizaines de quantième, et - un
mécanisme 90 d'entraînement des premier et deuxième mobiles.
- a first mobile 3 including a first toothing 31 and a
unit disk 32 bearingnumbers 33 intended to indicate the date units, - a second mobile 4 including a second toothing 41 and a
second dozen disc 42 bearingdigits 43 for indicating the date tens, and - a
mechanism 90 for driving the first and second mobiles.
Le mécanisme d'entraînement comprend :
- un
mobile 1 de commande comprenant :- une
troisième denture 1 a agencée de sorte à coopérer par obstacle, notamment par engrènement, avec lapremière denture 31, - une
quatrième denture 1 b agencée de sorte à coopérer par obstacle, notamment par engrènement, avec ladeuxième denture 41,
et
- une
- une roue d'entraînement 2 comprenant une
cinquième denture 2c agencée de sorte à coopérer par obstacle, notamment par engrènement, avec les troisième et quatrième dentures, unmême élément 99 de la cinquième denture, notamment unemême surface 99, en particulier une même surface s'étendant parallèlement ou sensiblement parallèlement à un axe A2 de rotation de la roue d'entraînement, étant agencé de sorte à coopérer avec les troisième et quatrième dentures.
- a control mobile 1 comprising:
- a
third toothing 1 arranged so as to cooperate by obstacle, in particular by meshing, with thefirst toothing 31, - a
fourth toothing 1b arranged to cooperate by obstacle, in particular by meshing, with thesecond toothing 41,
and
- a
- a
drive wheel 2 comprising afifth toothing 2c arranged to co-operate by obstacle, in particular by meshing, with the third and fourth teeth, thesame element 99 of the fifth toothing, in particular thesame surface 99, in particular the same surface extending parallel or substantially parallel to an axis A2 of rotation of the drive wheel, being arranged to cooperate with the third and fourth teeth.
La cinquième denture peut présenter une unique dent.The fifth set of teeth may have a single tooth.
De préférence, les troisième et quatrième dentures sont disposées selon deux plans P3 et P4 parallèles et distants ou, autrement dit sur deux niveaux. Les deux plans P3 et P4 ou les deux niveaux s'étendent perpendiculairement à un axe A1 de rotation du mobile de commande. Ainsi, la troisième denture 1a est formée sur un premier niveau ou au niveau d'un premier plan P3. Elle est prévue pour entraîner la première denture 31 d'une roue du premier mobile 3. La première denture 31 est solidaire du disque des unités 32. Par exemple, la première denture 31 est fixée au disque des unités 32. La quatrième denture 1b est formée sur un deuxième niveau ou au niveau d'un deuxième plan P4. Elle est prévue pour entraîner la deuxième denture 41 d'une roue du deuxième mobile 4. La deuxième denture 41 est solidaire du disque des dizaines 42. Par exemple, la deuxième denture 41 est fixée au disque des dizaines 42. De préférence, la première denture 31 se situe au niveau du premier plan P3, et la deuxième denture 41 se situe au niveau du deuxième plan P4. Autrement dit, préférentiellement, la première denture 31 intersecte le premier plan P3 et pas le deuxième plan P4, et la deuxième denture 41 intersecte le deuxième plan P4 et pas le premier plan P3.Preferably, the third and fourth teeth are arranged in two planes P3 and P4 parallel and distant or, in other words on two levels. The two planes P3 and P4 or both levels extend perpendicular to an axis A1 of rotation of the control wheel. Thus, the
L'élément 99 peut avantageusement être une dent ou une portion de surface de dent, comme une partie de profil formant une dent. Cet élément 99, notamment cette surface de dent, s'étend selon l'axe A2 de sorte à coopérer avec la troisième denture et avec la quatrième denture. Ainsi, l'élément 99 s'étend sur un premier niveau matérialisé par le plan P3 qui est par exemple le plan médian de la troisième denture. L'élément 99 s'étend aussi sur un deuxième niveau matérialisé par le plan P4 qui est par exemple le plan médian de la quatrième denture.The
Avantageusement, des dents de la quatrième denture, en particulier les surfaces actives de dents de la quatrième denture, se trouvent dans le prolongement, selon un axe A1 de rotation du mobile 1 de commande, de dents de la troisième denture, en particulier dans le prolongement, selon l'axe A1, de surfaces actives de dents de la troisième denture. Les surfaces actives sont les surfaces qui viennent en contact lors de l'engrènement.Advantageously, the teeth of the fourth toothing, in particular the active tooth surfaces of the fourth toothing, lie in the extension, along an axis A1 of rotation of the
Les troisième et quatrième dentures sont de préférence complémentaires et forment ensemble :
une sixième denture 1 c à trente et une dents ou à trente dents, et/ou- une denture présentant un pas angulaire d'un trente et unième de tour.
- a
sixth toothing 1c to thirty-one teeth or thirty teeth, and / or - a toothing having an angular pitch of a thirty-first round.
Ainsi, le mobile de commande 1 peut comprendre une troisième denture 1a et une quatrième denture 1b dont la combinaison, notamment la superposition, permet de former une denture résultante 1c. Cette superposition est avantageusement réalisée selon l'axe A1. Cette sixième denture résultante peut être apte à être actionnée de telle sorte que le mobile de commande 1 effectue un déplacement d'au moins un trente et unième de tour toutes les vingt-quatre heures ou parcourt un angle en degré de 360/31 en vingt-quatre heures. A cet effet, les profils des dentures 1a et 1b sont de préférence identiques ou sensiblement identiques.Thus, the
Le mobile de commande peut ainsi être agencé de sorte à effectuer un trente et unième de tour toutes les vingt-quatre heures.The control wheel can thus be arranged to perform a thirty-first round every twenty-four hours.
Le mobile de commande est de préférence monobloc ou fabriqué d'un seul tenant ou réalisé par assemblage, notamment par superposition, de deux éléments présentant respectivement les troisième et quatrième dentures. Par exemple, le mobile de commande peut être réalisé par assemblage d'au moins deux roues, notamment par fixation de deux roues l'une à l'autre.The control wheel is preferably monobloc or manufactured in one piece or made by assembling, in particular by superposition, two elements respectively having the third and fourth teeth. For example, the control wheel can be made by assembling at least two wheels, in particular by fixing two wheels to one another.
De préférence, les troisième et quatrième dentures sont des dentures externes. La cinquième denture peut aussi être une denture externe.Preferably, the third and fourth teeth are external teeth. The fifth set of teeth may also be external toothing.
De préférence, les premier et deuxième disques 32, 42 sont disposés sur un même plan P1 et/ou présentent chacun un même nombre de chiffres 33, 43, notamment dix chiffres, et/ou présentent le même diamètre ou sensiblement le même diamètre.Preferably, the first and
Dans ce premier mode de réalisation, les disques des dizaines et des unités portent chacun dix chiffres. Par exemple, le disque des dizaines porte deux fois une série de chiffres "0-1-1-2-3", tandis que le disque des unités indique une série de chiffres "0-1-2-3-4-5-6-7-8-9". Ainsi, les dentures 31 et 41 présentent un même nombre de dents, à savoir dix dents. Comme vu précédemment les profils des dentures peuvent être identiques ou sensiblement identiques.In this first embodiment, the tens and units disks each carry ten digits. For example, the tens disk carries twice a series of numbers "0-1-1-2-3", while the disk of the units indicates a series of numbers "0-1-2-3-4-5- 6-7-8-9 ". Thus, the
Dans le premier mode de réalisation, le nombre de dents de la troisième denture 1 a du mobile de commande 1 est différent de celui de la sixième denture résultante 1 c.In the first embodiment, the number of teeth of the
Comme représenté sur la
Les trente dents 10a et les cinq dents 10b sont agencées de façon à générer trente et une dents 10c sur la denture résultante 1 c. Pour ce faire, les dentures 1a et 1 b présentent toutes deux un pas angulaire de 360°/31, et une dent 10b est superposée au vide 98 sur la troisième denture 1a. Ce vide 98 est induit par l'absence de dent qui permet de ne pas faire déplacer le disque des unités du trente et unième quantième d'un mois donné au premier quantième du mois suivant. On peut ainsi passer de l'affichage « 31 » à l'affichage « 01 » et non passer de l'affichage « 31 » à l'affichage « 02 » si une dent était présente sur la troisième denture au niveau du vide 98.The thirty
Avantageusement, la dent 10b qui est superposée au vide 98 est prévue pour permettre l'entraînement du disque des dizaines à une date comprise entre le dixième et le vingtième quantième, par exemple lors du passage au quantième 20 comme représenté sur la
La troisième denture comprend trente dents, le pas angulaire entre les dents étant de 360°/31, soit un trente et unième detour.The third toothing comprises thirty teeth, the angular pitch between the teeth being 360 ° / 31, a thirty-first detour.
La quatrième denture peut comprendre cinq dents ou quatre dents, le pas angulaire entre deux dents étant un multiple de 360°/31 ou d'un trente et unième de tour.The fourth set of teeth may comprise five teeth or four teeth, the angular pitch between two teeth being a multiple of 360 ° / 31 or a thirty-first of a turn.
Un deuxième mode de réalisation d'une pièce d'horlogerie 220 selon l'invention est décrit ci-après en référence aux
Dans ce deuxième mode de réalisation, tout élément du dispositif d'affichage ayant la même structure et/ou la même fonction qu'un élément du dispositif d'affichage selon le premier mode de réalisation, porte la même référence que cet élément du dispositif d'affichage selon le premier mode de réalisation.In this second embodiment, any element of the display device having the same structure and / or the same function as an element of the display device according to the first embodiment, bears the same reference as this element of the display device. display according to the first embodiment.
Ce deuxième mode de réalisation diffère du premier mode de réalisation en ce que le nombre de dents de la troisième denture 1a du mobile de commande 1 est égal à celui de la sixième denture résultante 1 c comme représenté sur les
Comme dans le premier mode de réalisation, la troisième denture 1a peut comporter trente dents 10a. Ces dents sont chacune prévues pour entraîner, une fois durant le mois, la première roue portant la première denture 31 d'un dixième de tour avec la coopération d'un sautoir 5. Cette denture présente un pas angulaire de 360°/31 de tele sorte qu'un vide 98 permet de ne pas faire déplacer le disque des unités du trente et unième quantième d'un mois donné au premier quantième du mois suivant. La quatrième denture 1 b présente aussi un pas angulaire de 360°/31. Cette quatrième denture peut également comporter cinq dents 10b. Ces dents 10b sont chacune prévues pour entraîner, une fois durant le mois, la deuxième roue 4 portant la deuxième denture 41 d'un dixième de tour avec la coopération d'un sautoir 6. La sixième denture 1 c résultant de la superposition des troisième et quatrième dentures 1a et 1b, comporte trente dents 10c. Autrement dit, les dents 10b sont agencées de telle manière qu'aucune de ces dents n'est superposée au vide induit par l'absence de dent. Ainsi, la denture 1 c présente le même profil global que la denture 1a. Pour permettre un entraînement adéquat du mobile de commande 1, le sautoir 5 et/ou le sautoir 6 sont prévus pour repositionner angulairement les premier et deuxième mobiles. Pour ce faire, le sautoir 5 et/ou le sautoir 6 sont par exemple prévus pour entraîner le premier mobile et/ou le deuxième mobile avant que le premier mobile ou le deuxième mobile n'ait tourné d'un demi-pas, voire avant que le premier mobile ou le deuxième mobile n'ait tourné d'un tiers de pas. Par ailleurs, de manière avantageuse, le sautoir 5 et/ou le sautoir 6 sont prévus pour repositionner angulairement le mobile de commande après que le mobile de commande ait parcouru un angle d'une valeur de l'ordre d'un demi-pas angulaire, voire après que le mobile de commande ait parcouru un angle d'une valeur de l'ordre de trois-quarts de pas angulaire, sous l'effet de la roue d'entraînement 2. Ceci est par exemple réalisé par une conformation particulière des becs de sautoir, notamment par une géométrie particulière des becs de sautoir. La géométrie du bec peut à cet effet être dissymétrique, de sorte que le sommet du bec franchit le sommet d'une dent avant que le premier mobile ou le deuxième mobile n'ait tourné d'un demi-pas, voire avant que le premier mobile ou le deuxième mobile n'ait tourné d'un tiers de pas. Le repositionnement du mobile de commande est obtenu par utilisation d'un jeu adéquat entre les dentures 1 c et 31 et 1 c et 41, notamment entre les dentures 1 a et 31 et 1 b et 41.As in the first embodiment, the
Ce deuxième mode de réalisation a pour avantage de permettre de disposer la première denture 31 de la première roue du premier mobile sur toute la hauteur du mobile de commande 1, en particulier sur toute la hauteur de la sixième denture 1 c du mobile de commande 1. Ainsi, cette conception permet de s'affranchir des sécurités axiales nécessaires dans le premier mode de réalisation et qui sont, dans le premier mode de réalisation, prévues pour distinguer une première hauteur de denture 1a, dédiée à l'entraînement du premier mobile 3 comportant le disque des unités, et une deuxième hauteur de denture 1 b, dédiée à l'entraînement du deuxième mobile 4 comportant le disque des dizaines. Ainsi, la première denture 31 peut se situer aux niveaux des premier et deuxième plans P3 et P4, et la deuxième denture 41 peut se situer au niveau du deuxième plan P4. Autrement dit, la première denture 31 peut intersecter les premier et deuxième plans P3, P4, et la deuxième denture 41 peut intersecter le deuxième plan P4 et pas le premier plan P3. La hauteur du mobile de commande 1 peut ainsi être minimisée. Par conséquent, la hauteur du dispositif d'affichage de grande date peut également être réduite.This second embodiment has the advantage of making it possible to arrange the
Dans tous les modes de réalisation, la roue d'entraînement peut être solidaire d'une étoile 12. Cette étoile peut être située au centre du mouvement. L'étoile est prévue pour être actionnée une fois par jour par un doigt entraîneur de calendrier 13 comme représenté sur les
Dans tous les modes de réalisation, préférentiellement, le dispositif d'affichage peut comprendre un premier sautoir 5 associé au premier mobile, le premier sautoir et le premier mobile étant agencés de sorte à positionner le premier mobile dans la position suivante avant que le premier mobile n'ait parcouru un demi pas angulaire dans le sens de l'indication croissante des chiffres portés par le premier disque. Alternativement ou complémentairement, le dispositif d'affichage peut comprendre un deuxième sautoir 6 associé au deuxième mobile, le deuxième sautoir et le deuxième mobile étant agencés de sorte à positionner le deuxième mobile dans la position suivante avant que le deuxième mobile n'ait parcouru un demi pas angulaire dans le sens de l'indication croissante des chiffres portés par le deuxième disque.In all the embodiments, preferably, the display device may comprise a
Dans tous les modes de réalisation, préférentiellement, le dispositif d'affichage peut comprendre un sautoir 5 et/ou un sautoir 6 prévus pour repositionner angulairement le mobile de commande après que le mobile de commande ait parcouru un angle d'une valeur de l'ordre d'un demi-pas angulaire sous l'effet de la roue d'entraînement 2.In all embodiments, preferably, the display device may comprise a
Dans tous les modes de réalisation, les modules des première, deuxième, troisième, quatrième, cinquième et sixième dentures sont égaux ou sensiblement égaux, et sont de l'ordre de 0,2 à 0,3. Dans une variante de réalisation alternative, le module des dentures troisième, quatrième et sixième dentures peut être environ deux fois inférieur à celui des première et deuxième dentures 31 et 41 de façon à minimiser les jeux d'engrenages, comme représenté sur la
Dans tous les modes de réalisation, un angle a formé par une demi-droite ayant pour origine l'axe A1 de rotation du mobile de commande et passant par l'axe A3 de rotation du premier mobile et par une demi-droite ayant pour origine l'axe A1 de rotation du mobile de commande et passant par l'axe A4 de rotation du deuxième mobile est avantageusement inférieur à 170°, voire inférieur à 160°. Cet agencement permet de faire cohabiter les disques des dizaines et des unités dans un même plan de manière rapprochée, tout en affichant des polices de caractère sensiblement agrandies en regard de celles conventionnellement affichées par un disque des quantièmes classique. Une telle conformation est possible par le fait qu'un chiffre ou digit est dédoublé sur le disque des dizaines, par exemple le chiffre ou digit « 1 ».In all the embodiments, an angle formed by a half-line originating from the axis A1 of rotation of the control mobile and passing through the axis A3 of rotation of the first mobile and by a half-line having origin the axis A1 of rotation of the control wheel and passing through the axis A4 of rotation of the second wheel is advantageously less than 170 °, or even less than 160 °. This arrangement makes it possible to coexist the disks of the tens and units in the same plane closely, while displaying substantially enlarged fonts in comparison with those conventionally displayed by a conventional date disc. Such a conformation is possible by the fact that a digit or digit is split on the tens disk, for example the digit or digit "1".
Dans tous les modes de réalisation, comme représenté sur la
Dans les modes de réalisation, en particulier dans tous les modes de réalisation illustrés, le chiffre ou digit « 1 » est préférentiellement dédoublé sur le disque des dizaines. Alternativement, les digits « 0 », « 2 », « 3 », pourraient être dédoublés en modifiant la répartition des dents de la quatrième denture 1 b.In the embodiments, in particular in all the illustrated embodiments, the digit or digit "1" is preferentially split on the tens disk. Alternatively, the digits "0", "2", "3" could be split by changing the distribution of the teeth of the
Les digits « 0 » sur le disque des dizaines peuvent ne pas être représentés. Dans ce cas, des secteurs de disque peuvent ne pas présenter de digit.Digits "0" on the tens disk may not be shown. In this case, disk sectors may not have a digit.
Le dispositif d'affichage d'une indication horaire, notamment le dispositif d'affichage de quantième, selon l'invention permet donc d'utiliser deux disques qui sont disposés dans un même plan et qui présentent sensiblement le même diamètre. Ces disques peuvent être solidaires de roues dotées préférentiellement d'un même profil de denture et du même nombre de dents, à savoir dix dents, qui sont prévues pour être actionnées par un mobile de commande comprenant une troisième denture et une quatrième denture de même profil dont la superposition permet de former une sixième denture résultante apte à être actionnée de telle sorte que le mobile de commande effectue au moins un trente et unième de tour toutes les vingt-quatre heures.The device for displaying a time indication, in particular the date display device, according to the invention thus makes it possible to use two disks which are arranged in the same plane and which have substantially the same diameter. These disks may be integral with wheels preferably having the same tooth profile and the same number of teeth, namely ten teeth, which are intended to be actuated by a control wheel comprising a third toothing and a fourth toothing of the same profile. whose superposition makes it possible to form a sixth resultant toothing capable of being actuated so that the control wheel performs at least thirty-first of a turn every twenty-four hours.
Un tel agencement permet de minimiser le nombre de composants qui constituent le mobile de commande.Such an arrangement makes it possible to minimize the number of components constituting the control mobile.
La solution permet également de minimiser la hauteur du mobile de commande. Celui-ci est formé d'au minimum deux niveaux qui correspondent respectivement à la hauteur de la troisième denture et à celle de la quatrième denture. Ainsi, celui-ci se distingue des mobiles de commande de l'art antérieur qui sont constitués de trois niveaux. Une telle construction offre par exemple l'opportunité d'adjoindre des fonctions connexes au mobile de commande, telle qu'une fonction de verrouillage d'au moins un des deux disques d'affichage.The solution also makes it possible to minimize the height of the control wheel. This is formed by at least two levels which correspond respectively to the height of the third toothing and that of the fourth toothing. Thus, it differs from the control mobiles of the prior art which consist of three levels. Such a construction offers for example the opportunity to add functions related to the control mobile, such as a locking function of at least one of the two display disks.
Le mobile de commande peut être en prise directe avec une roue d'entraînement qui présente un profil de denture identique ou sensiblement identique au profil résultant du mobile de commande.The control wheel can be in direct contact with a drive wheel which has a gear profile identical or substantially identical to the profile resulting from the control wheel.
Le dispositif d'affichage d'une indication horaire, notamment le dispositif d'affichage de quantième, peut également être réglé par des moyens de correction communs à d'autres dispositifs d'affichage tels qu'un dispositif d'affichage de l'indication des jours.The device for displaying a time indication, in particular the date display device, may also be set by correction means common to other display devices such as a display device for the indication. days.
Le dispositif d'affichage d'une indication horaire, notamment le dispositif d'affichage de quantième, peut être intégré au sein d'un module prévu pour être rapporté sur un mouvement de base. Celui-ci peut par exemple se substituer à un module prévu pour afficher le jour de la semaine.The device for displaying a time indication, in particular the date display device, may be integrated within a module intended to be attached to a basic movement. This one can for example replace a module intended to display the day of the week.
Dans une variante compatible avec les différents modes de réalisation, la deuxième denture peut présenter un nombre de dents différent de celui de la première denture. Par exemple, la deuxième denture peut présenter huit dents et le deuxième disque peut indiquer huit digits (deux fois la série de chiffres "0-1-2-3"). Dans ce cas de figure, la quatrième denture 1 b du mobile de commande comporte quatre dents. Ces quatre dents sont chacune prévues pour entraîner, une fois durant le mois, le deuxième mobile 41 d'un huitième de tour avec la coopération du sautoir 6.In a variant compatible with the different embodiments, the second toothing may have a number of teeth different from that of the first toothing. For example, the second toothing may have eight teeth and the second disc may indicate eight digits (twice the number series "0-1-2-3"). In this case, the
Dans les différents modes de réalisation décrits précédemment, le dispositif d'affichage est un dispositif d'affichage de quantième. Alternativement, le dispositif d'affichage selon l'invention peut par exemple être prévu pour indiquer une information horaire ou dérivée de l'heure telle que le comptage des minutes d'un temps chronométré par un mécanisme connexe de chronographe.In the various embodiments described above, the display device is a date display device. Alternatively, the display device according to the invention may, for example, be provided to indicate hourly or time-derived information such as the counting of the minutes of a time timed by a related chronograph mechanism.
Ainsi, de manière identique à ce qui a été décrit précédemment, un dispositif d'affichage des minutes peut comprendre :
- un premier mobile 3 incluant une première
denture 31 etun disque d'unités 32 portant des chiffres 33 destinés à indiquer les unités des minutes, - un deuxième mobile 4 incluant une deuxième
denture 41 et un deuxième disque de dizaines 42 portant des chiffres 43 destinés à indiquer les dizaines des minutes, et un mécanisme 90 qui est capable d'entraîner les premier et deuxième mobiles.
- a first mobile 3 including a first set of
teeth 31 and aunit disk 32bearing numbers 33 intended to indicate the minutes units, - a second mobile 4 including a second set of
teeth 41 and asecond dozen disc 42 bearingdigits 43 for indicating the tens of minutes, and - a
mechanism 90 that is capable of driving the first and second mobiles.
Par exemple, le disque des dizaines porte deux fois une série de chiffres "0-1-1-2-3", tandis que le disque des unités indique une série de chiffres "0-1-2-3-4-5-6-7-8-9". Ainsi, les dentures 31 et 41 peuvent présenter un même nombre de dents, à savoir dix dents. Dans ce cas de figure, le dispositif d'affichage constitue un compteur des minutes de chronographe qui est capable d'indiquer un temps chronométré inférieur ou égal à trente minutes. Le mécanisme d'entraînement 90 peut comprendre un mobile 1 effectuant un tour complet en trente minutes. Celui-ci peut comprendre une troisième denture 1a, constituée par exemple de 30 dents, agencée de sorte à coopérer par obstacle, notamment par engrènement, avec la première denture 31, ainsi qu'une quatrième denture 1b, constituée par exemple de 5 dents, agencée de sorte à coopérer par obstacle, notamment par engrènement, avec la deuxième denture 41. Le mécanisme d'entraînement 90 peut comprendre également une roue d'entraînement 2 effectuant un tour complet en une minute. Celle-ci présente une cinquième denture 2c qui se réduit ici à une unique dent qui peut par exemple se présenter sous la forme d'un doigt entraîneur des minutes.For example, the tens disk carries twice a series of numbers "0-1-1-2-3", while the disk of the units indicates a series of numbers "0-1-2-3-4-5- 6-7-8-9 ". Thus, the
Le dispositif d'affichage selon l'invention peut bien entendu être prévu pour indiquer toute autre information horaire ou dérivée de l'heure, par exemple une information calendaire comme l'indication du mois ou une indication des minutes sur soixante minutes ou une indication des heures sur douze ou vingt-quatre heures.The display device according to the invention can of course be provided to indicate any other information hourly or derived from the time, for example a calendar information such as the indication of the month or an indication of minutes in sixty minutes or an indication of hours in twelve or twenty-four hours.
