Definitions
- the present invention relates to a mechanism for calendar for watch movement and more particularly such a mechanism allowing the display large dates.
- Wrist watches with a device date display with classic windows generally the disadvantage of being difficult to read due to the small size of the counters and the numbers transferred onto the indicator organs visible through these counters.
- the ring further includes an additional tooth which, when passage from the second "zero" to the first "one” of the units, leads with a step a four-pointed star carrying the digits of tens of dates, i.e. digits "zero", "one", "two” and "three".
- the main object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a date display mechanism of large dimensions and therefore more readable, yes mechanism requires only extremely simple means and little manufacturing modifications of the basic movement in which it is integrated.
- the invention relates to a mechanism for date for a watch movement comprising a member tens indicator with four positions bearing a graduation from “zero” to “three” or from “one” to “three” more a blank, designed to take at least one step every ten days, and a unit indicating unit planned for take one step every twenty-four hours, characterized by what the unit indicator can occupy thirty-one positions and carries three graduations from “zero” to “nine” successive, one of the three graduations having a "one” extra inserted between its "zero” and its “one".
- the date according to the invention allows, on the one hand, to display large calendars and, on the other hand, the change from the end of the month to thirty-one days on the first day of the following month without acting on a correction.
- the transition from the end of the month to the first day of following month is done using a mechanism of correction of classic dates.
- the unit indicator body is associated with a first toothing with thirty-one teeth which cooperates with an organ coach, and a second toothing having four teeth of which three teeth drive the indicator organ of tens when crossing the "zero" of a graduation of the unit indicating unit at the "one” of the graduation next, while the fourth tooth drives the organ tens indicator when passing "one" additional from the graduation modified to the next "one".
- the organ unit indicator consists of an annular disc and the first and second teeth are teeth interior spaces that extend into two different planes.
- the watch shown schematically in Figure 1 includes a date mechanism designated by the general numerical reference 1.
- the watch includes also other indicator mechanisms and organs. These will however not be described here since they are known to those skilled in the art and that they do not relate by directly the date mechanism according to the present invention.
- the watch equipped of the date mechanism 1 comprises a dial 2 provided with two windows 4, 6 juxtaposed with six hours which in another form of execution could be brought together in one large window.
- Window 4 leaves appear a figure relating to the tens of a calendar, while the window 6 reveals a number relating to the units of a date so as to allow, according to their relative positions, the indication of digits from "one" to "thirty-one".
- the tens indicator body 8 carries a graduation from “zero” to “three” or from “one” to “three” more one blank, and is scheduled to take one step every ten days.
- the indicator unit 10 has three successive graduations 10a, 10b, and 10c from “zero” to "new", the 10c graduation, known as modified graduation, having an additional "a” inserted between its "zero” and its "a”.
- the indicator member 8 can occupy four positions different, while the indicator member 10 can occupy thirty-one different positions.
- the organ unit indicator 10 consists of an annular disc associated with a first internal toothing 12 comprising thirty-one teeth.
- a driving member 14 having the shape of a training finger and belonging to a basic movement M conventionally turns every twenty-four hours, training in a conventional manner the annular disc 10 by action on the teeth 12.
- a long necklace (not shown) secured to the basic movement M acts on the teeth 12 to hold the annular disc 10 in place when not driven.
- the organ unit indicator 10 is also associated with a second internal toothing 16 having four teeth 16a, 16b, 16c, and 16d.
- teeth are distributed at the inner periphery of the annular disc 10 so that they drive the tens indicator body 8 during the respective passage of the "zero" of the graduations 10a, 10b and 10c from the indicator unit 10 to the "one” of the next graduation.
- the fourth tooth 16d drives the tens indicator body 8 when passing the "one” additional graduation modified 10c to "one” following this same graduation.
- the teeth 12 and 16 extend in two different planes, the teeth 16 cooperating with a star 18 with four teeth secured to the indicator member of the tens 8, star 18 being positioned by a jumper 20.
- the indicator body of the tens 8 moves above the annular disc 10 and includes cutouts that reveal the number units carried by said annular disc 10 and in front be displayed through window 6.
- the tens indicator 8 consists of a disc cut in the shape of a cross with four branches, the branches marked with the numbers “zero”, “one", “two” respectively and “three” as shown, or "one", "two", “three” and a white.
- the mechanism according to the invention further comprises a support plate 22 of the star 18, of the tens cross 8 and the annular disc of the units 10.
- This plate 22 is arranged on the surface of the basic movement M at which is associated with the date mechanism according to the invention. More specifically, the star 18 is rotatably mounted in a recess 24 made in the upper surface 26 of plate 22, the tens cross 8, integral with the star 18, extending in a second recess 28 also produced in surface 26 and located between this surface and the bottom of the recess 24.
- the plate 22 also includes, dug in its surface 26, a path annular 30 on which the indicator member of the units 10. This annular path 30 includes a recess 32 in which the internal teeth 12 extend to cooperate with the training finger 14.
- the drive finger 14 acts once every twenty-four hours on toothing 12 to advance the disc annular 10 of a thirty-first of a turn. So a digit of any unit of date appeared, by example, at midnight in window 6, will be replaced when passage at midnight following by the number which makes it after.
- the finger drive 14 acts on the teeth 12, as described above, to pass the "nine" of the graduation of units corresponding to "zero” of the following graduation, teeth 16a, 16b and 16c of teeth 16 acting on the star 18 to simultaneously pass the number of tens from “zero” to "one", from “one” to “two” and from “two” to “three” respectively.
- teeth 16a, 16b, and 16c are arranged respectively appreciably opposite the figures "eight" graduations 10a, 10b, 10c.
- the drive finger 14 acts normally on the teeth 12, as described above, and passes the "zero" of the graduation of units 10b at the first "one” of the graduation of units 10c, none of the teeth of toothing 16 not acting at this moment on the star 18, so that the cross 10 remains stationary and always displays the "three" of tens.
- the date mechanism according to the invention is designed so that the cross 8 tens performs one revolution per month in four steps, the same tooth of the teeth 16 always producing the display of the same figure, while the annular disc makes a turn every thirty-one days.
- the change from the last day of this month to "one" of the following month can be performed using a correction device 34 with sliding pinion and rocker known per se which acts directly on the teeth 12 of the annular disc 10.

Abstract
Description
La présente invention concerne un mécanisme de quantième pour mouvement d'horlogerie et plus particulièrement un tel mécanisme permettant l'affichage de quantièmes de grandes dimensions.The present invention relates to a mechanism for calendar for watch movement and more particularly such a mechanism allowing the display large dates.
Les montres-bracelets comportant un dispositif d'affichage de quantièmes à guichets classiques présentent généralement l'inconvénient d'être peu lisibles du fait de la petitesse des guichets et des chiffres décalqués sur les organes indicateurs visibles à travers ces guichets.Wrist watches with a device date display with classic windows generally the disadvantage of being difficult to read due to the small size of the counters and the numbers transferred onto the indicator organs visible through these counters.
On connaít déjà par le brevet CH 342 270 un mécanisme indicateur de quantièmes de grandes dimensions pour montre-calendrier comprenant une roue intermédiaire effectuant deux tours par jour et dont toutes les dents sont tronquées sauf une. Cette dernière agit sur un anneau denté à vingt dents oui porte les chiffres des unités des quantièmes et gui est visible à travers un grand guichet. Chacun de ces chiffres est répété deux fois de suite sur cet anneau. Ainsi un chiffre d'unité quelconque apparu à minuit dans le guichet est remplacé à midi, au deuxième tour de la roue intermédiaire, par un second chiffre identique qui ne disparaítra qu'au minuit suivant pour laisser apparaítre le chiffre d'unité suivant. L'anneau comporte en outre une dent supplémentaire qui, lors du passage du deuxième "zéro" au premier "un" des unités, entraíne d'un pas une étoile à quatre branches portant les chiffres des dizaines des quantièmes, c'est-à-dire les chiffres "zéro", "un", "deux" et "trois".We already know from patent CH 342 270 a mechanism large date indicator for calendar watch including an intermediate wheel performing two rounds a day and all of whose teeth except one. The latter acts on a ring toothed with twenty teeth yes carries the unit numbers of the dates and mistletoe is visible through a large window. Each of these figures is repeated twice in succession on this ring. Thus any unit figure appeared at midnight in the counter is replaced at noon on the second revolution of the intermediate wheel, by a second digit identical which will not disappear until the next midnight for let appear the following unit figure. The ring further includes an additional tooth which, when passage from the second "zero" to the first "one" of the units, leads with a step a four-pointed star carrying the digits of tens of dates, i.e. digits "zero", "one", "two" and "three".
Avec ce mécanisme, il est toutefois nécessaire d'agir sur l'anneau des unités et sur l'étoile des dizaines en fin de mois pour pouvoir passer respectivement du vingthuitième, vingt-neuvième et trente et unième jour d'une fin de mois au premier jour du mois suivant. Ceci nécessite donc l'utilisation d'un mécanisme de correction complexe qui doit permettre notamment le déplacement de l'étoile des dizaines d'un pas sans déplacement concomitant de l'anneau des unités. De tels mécanismes nécessitent généralement l'utilisation de dispositifs de débrayage de l'anneau des unités oui compliquent la réalisation de ces mécanismes et les rendent ainsi plus chers et plus volumineux.With this mechanism, however, it is necessary to act on the unit ring and on the tens star in end of the month to be able to move respectively from the twenty-eighth, twenty-ninth and thirty-first day of a end of month on the first day of the following month. This therefore requires the use of a correction mechanism complex which must allow in particular the displacement of the star of the tens of a step without displacement concomitant of the ring of units. Such mechanisms generally require the use of declutching the unit ring yes complicate the realization of these mechanisms and thus make them more expensive and larger.
La présente invention a pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant un mécanisme d'affichage de quantièmes de grandes dimensions et donc plus lisibles, mécanisme oui ne nécessite que des moyens extrêmement simples et que peu de modifications de fabrication du mouvement de base dans lequel il est intégré.The main object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a date display mechanism of large dimensions and therefore more readable, yes mechanism requires only extremely simple means and little manufacturing modifications of the basic movement in which it is integrated.
A cet effet, l'invention a pour objet un mécanisme de quantième pour mouvement d'horlogerie comprenant un organe indicateur des dizaines à quatre positions portant une graduation de "zéro" à "trois" ou de "un" à "trois" plus un blanc, prévu pour effectuer au moins un pas tous les dix jours, et un organe indicateur des unités prévu pour effectuer un pas par vingt-quatre heures, caractérisé en ce que l'indicateur des unités peut occuper trente et une positions et porte trois graduations de "zéro" à "neuf" successives, une des trois graduations ayant un "un" supplémentaire intercalé entre son "zéro" et son "un".To this end, the invention relates to a mechanism for date for a watch movement comprising a member tens indicator with four positions bearing a graduation from "zero" to "three" or from "one" to "three" more a blank, designed to take at least one step every ten days, and a unit indicating unit planned for take one step every twenty-four hours, characterized by what the unit indicator can occupy thirty-one positions and carries three graduations from "zero" to "nine" successive, one of the three graduations having a "one" extra inserted between its "zero" and its "one".
Grâce à ces caractéristiques, le mécanisme de quantième selon l'invention permet, d'une part, d'afficher des quantièmes de grandes dimensions et, d'autre part, le passage d'une fin de mois à trente et un jours au premier jour du mois suivant sans agir sur un mécanisme de correction. Dans le cas d'un mois de moins de trente et un jours, le passage d'une fin de mois au premier jour du mois suivant s'effectue en utilisant un mécanisme de correction des quantièmes classiques.Thanks to these characteristics, the date according to the invention allows, on the one hand, to display large calendars and, on the other hand, the change from the end of the month to thirty-one days on the first day of the following month without acting on a correction. In the case of a month of less than thirty-one days, the transition from the end of the month to the first day of following month is done using a mechanism of correction of classic dates.
Selon une caractéristique avantageuse de l'invention, l'organe indicateur des unités est associé à une première denture à trente et une dents qui coopère avec un organe entraíneur, et à une seconde denture comportant quatre dents dont trois dents entraínent l'organe indicateur des dizaines lors du passage du "zéro" d'une graduation de l'organe indicateur des unités au "un" de la graduation suivante, tandis que la quatrième dent entraíne l'organe indicateur des dizaines lors du passage du "un" supplémentaire de la graduation modifiée au "un" suivant.According to an advantageous characteristic of the invention, the unit indicator body is associated with a first toothing with thirty-one teeth which cooperates with an organ coach, and a second toothing having four teeth of which three teeth drive the indicator organ of tens when crossing the "zero" of a graduation of the unit indicating unit at the "one" of the graduation next, while the fourth tooth drives the organ tens indicator when passing "one" additional from the graduation modified to the next "one".
Selon un mode de réalisation préféré, l'organe indicateur des unités consiste en un disque annulaire et les première et deuxième dentures sont des dentures intérieures qui s étendent dans deux plans différents.According to a preferred embodiment, the organ unit indicator consists of an annular disc and the first and second teeth are teeth interior spaces that extend into two different planes.
D'autres caractéristiques et avantages de la présente invention apparaítront dans la description suivante d'un mode de réalisation préféré, présenté à titre d'exemple non limitatif en référence aux dessins annexés, dans lesquels :

- Figure 1 is a plan view of a watch equipped with a date mechanism according to the invention;
- Figure 2 is a plan view of the date mechanism according to the invention;
- FIG. 3 is a half plan view in which the tens indicator and the units indicator have been partially broken away, and

La montre représentée schématiquement à la figure 1
comporte un mécanisme de quantième désigné par la
référence numérique générale 1. La montre comprend
également d'autres mécanismes et organes indicateurs.
Ceux-ci ne seront toutefois pas décrits ici puisqu'ils
sont connus de l'homme du métier et qu'ils ne concernent
par directement le mécanisme de quantième selon la
présente invention.The watch shown schematically in Figure 1
includes a date mechanism designated by the
general
On voit également à la figure 1 que la montre équipée
du mécanisme de quantième 1 selon l'invention comprend un
cadran 2 muni de deux guichets 4, 6 juxtaposés à six
heures qui dans une autre forme d'exécution pourraient
être réunis en un seul grand guichet. Le guichet 4 laisse
apparaítre un chiffre relatif aux dizaines d'un quantième,
tandis que le guichet 6 laisse apparaítre un chiffre
relatif aux unités d'un quantième de manière à permettre,
suivant leurs positions relatives, l'indication des
chiffres de "un" à "trente et un".We also see in Figure 1 that the watch equipped
of the
Comme cela est visible sur la figure 2, ces chiffres
sont portés par deux organes indicateurs 8, 10 différents,
respectivement l'organe indicateur des dizaines 8 et
l'organe indicateur des unités 10. L'affichage des
quantièmes à l'aide de ces deux organes 8, 10 permet ainsi
d'augmenter les dimensions respectives des chiffres portés
par chacun de ces organes 8 et 10 et de rendre la lecture
des quantièmes plus aisée.As can be seen in Figure 2, these numbers
are carried by two
L'organe indicateur des dizaines 8 porte une
graduation de "zéro" à "trois" ou de "un" à "trois" plus
un blanc, et est prévu pour effectuer un pas tous les dix
jours. L'organe indicateur des unités 10 porte trois
graduations 10a, 10b, et 10c successives de "zéro" à
"neuf", la graduation 10c, dite graduation modifiée, ayant
un "un" supplémentaire intercalé entre son "zéro" et son
"un". L'organe indicateur 8 peut occuper quatre positions
différentes, tandis que l'organe indicateur 10 peut
occuper trente et une positions différentes.The
En référence aux figures 2 à 4, on voit que l'organe
indicateur des unités 10 consiste en un disque annulaire
associé à une première denture intérieure 12 comportant
trente et une dents. Un organe entraíneur 14 ayant la
forme d'un doigt d'entraínement et appartenant à un
mouvement de base M fait classiquement un tour toutes les
vingt-quatre heures, entraínant de façon conventionnelle
le disque annulaire 10 par action sur la denture 12. Un
sautoir (non représenté) solidaire du mouvement de base M
agit sur la denture 12 pour maintenir le disque annulaire
10 en place lorsqu'il n'est pas entraíné. L'organe
indicateur des unités 10 est également associé à une
deuxième denture intérieure 16 comportant quatre dents
16a, 16b, 16c, et 16d. Ces dents sont réparties à la
périphérie intérieure du disque annulaire 10 de sorte
qu'elles entraínent l'organe indicateur des dizaines 8
lors du passage respectif du "zéro" des graduations 10a,
10b et 10c de l'organe indicateur des unités 10 au "un" de
la graduation suivante. La quatrième dent 16d entraíne
l'organe indicateur des dizaines 8 lors du passage du "un"
supplémentaire de la graduation modifiée 10c au "un"
suivant de cette même graduation.Referring to Figures 2 to 4, we see that the
En se référant plus particulièrement à la figure 4,
on voit que les dentures 12 et 16 s'étendent dans deux
plans différents, la denture 16 coopérant avec une étoile
18 à quatre dents solidaire de l'organe indicateur des
dizaines 8, l'étoile 18 étant positionnée par un sautoir
20.With particular reference to Figure 4,
we see that the
Dans l'exemple illustré, l'organe indicateur des
dizaines 8 se déplace au-dessus du disque annulaire 10 et
comprend des découpes qui laissent apparaítre le chiffre
des unités porté par ledit disque annulaire 10 et devant
être affiché à travers le guichet 6. De préférence,
l'organe indicateur des dizaines 8 consiste en un disque
découpé en forme de croix à quatre branches, les branches
portant respectivement les chiffres "zéro", "un", "deux"
et "trois" comme cela est illustré, ou "un", "deux",
"trois" et un blanc.In the example illustrated, the indicator body of the
Le mécanisme selon l'invention comprend en outre une
plaque-support 22 de l'étoile 18, de la croix des dizaines
8 et du disque annulaire des unités 10. Cette plaque 22
est disposée à la surface du mouvement de base M auquel
est associé le mécanisme de quantième selon l'invention.
Plus précisément, l'étoile 18 est montée à rotation dans
une creusure 24 réalisée dans la surface supérieure 26 de
la plaque 22, la croix des dizaines 8, solidaire de
l'étoile 18, s'étendant dans une deuxième creusure 28
également réalisée dans la surface 26 et située entre
cette surface et le fond de la creusure 24. La plaque 22
comprend également, creusé dans sa surface 26, un chemin
annulaire 30 sur lequel se déplace l'organe indicateur des
unités 10. Ce chemin annulaire 30 comprend un évidement 32
dans lequel s'étend la denture intérieure 12 pour coopérer
avec le doigt d'entraínement 14.The mechanism according to the invention further comprises a
Nous allons maintenant décrire le fonctionnement du
mécanisme de quantième selon la présente invention. Le
doigt d'entraínement 14 agit une fois par vingt-quatre
heures sur la denture 12 pour faire avancer le disque
annulaire 10 d'un trente et unième de tour. Ainsi, un
chiffre d'une unité quelconque de quantième apparu, par
exemple, à minuit dans le guichet 6, sera remplacé lors du
passage au minuit suivant par le chiffre qui lui fait
suite.We will now describe how the
date mechanism according to the present invention. The
Au "dix", "vingt" et "trente" du mois, le doigt
d'entraínement 14 agit sur la denture 12, comme décrit ci-dessus,
pour faire passer le "neuf" de la graduation des
unités correspondante au "zéro" de la graduation suivante,
les dents 16a, 16b et 16c de la denture 16 agissant sur
l'étoile 18 pour faire simultanément passer le chiffre des
dizaines du "zéro" au "un", du "un" au "deux" et du "deux"
au "trois" respectivement.At the "ten", "twenty" and "thirty" of the month, the
On notera à ce propos que dans le mode de réalisation
illustré, les dents 16a, 16b, et 16c sont disposées
respectivement sensiblement en regard des chiffres "huit"
des graduations 10a, 10b, 10c.Note in this regard that in the embodiment
illustrated, the
Lors du passage du "trente" au "trente et un", le
doigt d'entraínement 14 agit normalement sur la denture
12, comme décrit ci-dessus, et fait passer le "zéro" de la
graduation des unités 10b au premier "un" de la graduation
des unités 10c, aucune des dents de la denture 16
n'agissant à cet instant sur l'étoile 18, de sorte que la
croix 10 reste immobile et affiche toujours le "trois" des
dizaines.When changing from "thirty" to "thirty-one", the
Lors du passage du "trente et un" d'un mois au "un"
du mois suivant le doigt d'entraínement 14 agit
normalement sur la denture 12, comme décrit ci-dessus, et
fait passer le premier "un" de la graduation des unités
10c au deuxième "un" de cette même graduation.
Simultanément, la dent 16d de la denture 16 agit sur
l'étoile 18 pour faire passer le chiffre "trois" porté par
la croix des dizaines 10 au "zéro" ou à une plage
d'affichage blanche.When switching from "thirty-one" a month to "one"
of the month following the
On comprend ainsi que le mécanisme de quantième selon
l'invention est conçu de sorte que la croix 8 des dizaines
effectue un tour par mois selon quatre pas, la même dent
de la denture 16 produisant toujours l'affichage du même
chiffre, tandis que le disque annulaire effectue un tour
tous les trente et un jours.It is thus understood that the date mechanism according to
the invention is designed so that the
Dans le cas d'un mois de trente et un jours, le
passage du dernier jour de ce mois au "un" du mois suivant
peut être effectué à l'aide d'un dispositif de correction
34 à pignon coulant et bascule connu en soi qui agit
directement sur la denture 12 du disque annulaire 10. Le
dispositif 34 comprend notamment une roue 36 en prise avec
un pignon baladeur 38 à trois dents. Dans un premier sens
de rotation de la tige de correction 40 partiellement
représentée, la roue 36 entraíne le pignon 38 guidé dans
un trou oblong (non représenté) pour venir en prise avec
la denture 12 du disque annulaire 10. Ce dernier est alors
déplacé dans le sens horaire du nombre de pas nécessaire
pour faire apparaítre le deuxième "un" de la graduation
10c dans le guichet 6. De façon classique, le pignon 38
est dégagé de la denture 12 lorsque la tige 40 est
actionnée dans le sens de rotation opposé au premier sens.
On notera que le mécanisme de quantième selon l'invention
peut, sans modification majeure, utiliser le dispositif de
correction de quantièmes d'un mouvement classique.
L'utilisation d'un tel mécanisme de correction permet
d'assurer manuellement le passage de la fin d'un mois de
moins de trente et un jours au premier jour du mois
suivant aisément et rapidement.In the case of a thirty-one day month, the
change from the last day of this month to "one" of the following month
can be performed using a
Certaines modifications peuvent être apportées au
mécanisme de quantième qui vient d'être décrit sans pour
autant sortir du cadre de cette invention. Ainsi, par
exemple, on pourrait envisager de déplacer l'axe de
rotation de la croix 8 des dizaines vers le centre du
mouvement M afin qu'elle ne se déplace plus au-dessus du
disque annulaire 10, mais vienne se déplacer en
juxtaposition de celui-ci. Dans ce cas, le guichet 4
serait bien entendu disposé au-dessus du guichet 6 sur
l'axe 12 heures 6 heures.Some changes can be made to the
date mechanism which has just been described without
as well go beyond the scope of this invention. So by
example, we could consider moving the axis of
rotation of the
