Description

Domaine techniqueTechnical area

La présente invention concerne une pièce d'horlogerie comportant un mécanisme d'affichage agencé pour commander les déplacements d'un organe d'affichage en regard d'une échelle indicatrice comportant différentes indications présentant au moins deux largeurs différentes et étant séparées les unes des autres par des espaces de séparation correspondants.The present invention relates to a timepiece comprising a display mechanism arranged to control the movements of a display member facing an indicator scale comprising different indications having at least two different widths and being separated from each other. by corresponding separation spaces.

Etat de la techniqueState of the art

De telles pièces d'horlogerie sont bien connues depuis longtemps dans l'art antérieur.Such timepieces have been well known for a long time in the prior art.

Ainsi, par exemple, on connaît DE 17 69 783 U , ou encore les pièces d'horlogerie qui comportent un mécanisme d'affichage du quantième par une aiguille et répondent la plupart du temps aux caractéristiques énoncées ci-dessus. En effet, si les indications des vingtaines et des trentaines peuvent éventuellement présenter une seule et même largeur, les indications des dizaines présentent typiquement une largeur plus faible puisque le "1" présente une largeur moindre que celle du "2" et/ou du "3", et les indications des unités présentent typiquement une largeur encore plus faible puisqu'elles ne comportent qu'un seul chiffre. Ces mécanismes d'affichage comprennent généralement un organe d'affichage entrainé par l'intermédiaire d'un rouage conventionnel, pour se déplacer en regard des différentes indications avec un pas de déplacement constant. Ainsi, les espaces de séparation situés entre les indications présentent, eux, une largeur variable pour permettre d'entrainer l'organe d'affichage suivant un pas constant malgré la largeur variable des indications.So, for example, we know DE 17 69 783 U , or even timepieces which include a mechanism for displaying the date by a hand and most of the time meet the characteristics set out above. Indeed, if the indications of the twenties and thirties may possibly have one and the same width, the indications of the tens typically have a smaller width since the "1" has a smaller width than that of the "2" and/or the "3", and unit indications are typically even narrower as they are only one digit long. These display mechanisms generally comprise a display member driven by means of a conventional gear train, to move opposite the various indications with a constant displacement pitch. Thus, the separation spaces located between the indications have, themselves, a variable width to enable the display member to be driven along a constant pitch despite the variable width of the indications.

Ces constructions entrainent justement une apparence irrégulière des échelles indicatrices correspondantes, du fait que les indications comportant deux chiffres soient plus serrées les unes contre les autres que les indications des unités, ceci étant plus particulièrement marqué au niveau des indications des vingtaines et des trentaines.These constructions lead precisely to an irregular appearance of the corresponding indicator scales, due to the fact that the indications comprising two figures are closer together than the indications of the units, this being more particularly marked at the level of the indications of the twenties and thirties.

Par ailleurs, plus la surface d'affichage de ces indications est réduite, plus cette apparence irrégulière est amplifiée. Ainsi, par exemple, les indications à deux chiffres du quantième apparaissent comme particulièrement proches les unes des autres lorsque le quantième est affiché dans un petit compteur.Moreover, the more the display surface of these indications is reduced, the more this irregular appearance is amplified. Thus, for example, the indications two digits of the date appear particularly close to each other when the date is displayed in a small counter.

Divulgation de l'inventionDisclosure of Invention

Un but principal de la présente invention est de proposer une pièce d'horlogerie offrant une présentation alternative en référence aux pièces d'horlogerie connues en termes d'affichage, notamment une lisibilité améliorée.A main object of the present invention is to provide a timepiece offering an alternative presentation with reference to known timepieces in terms of display, in particular improved readability.

A cet effet, la présente invention concerne plus particulièrement une pièce d'horlogerie du type indiqué plus haut, caractérisée par le fait que les espaces de séparation présentent tous sensiblement une même largeur, et par le fait que le mécanisme d'affichage comporte

  • un mobile d'affichage agencé pour commander les déplacements de l'organe d'affichage, et
  • un mécanisme d'actionnement agencé pour coopérer avec le mobile d'affichage et le déplacer suivant différentes positions successives associées aux indications, de telle manière que les différentes positions successives présentent entre elles au moins deux pas différents.
To this end, the present invention relates more particularly to a timepiece of the type indicated above, characterized in that the separation spaces all have substantially the same width, and in that the display mechanism comprises
  • a mobile display arranged to control the movements of the display member, and
  • an actuating mechanism arranged to cooperate with the mobile display and move it along different successive positions associated with the indications, such that the different successive positions have between them at least two different pitches.

Grâce à ces caractéristiques, l'affichage associé au mécanisme selon l'invention apparait plus homogène et aéré que les affichages de l'art antérieur et est par conséquent plus lisible que ces derniers.Thanks to these characteristics, the display associated with the mechanism according to the invention appears more homogeneous and airy than the displays of the prior art and is consequently more readable than the latter.

Selon un premier mode de réalisation préféré, le mécanisme d'actionnement peut comporter une came contre laquelle un palpeur est agencé en appui, le palpeur étant lié cinématiquement au mobile d'affichage, la came présentant au moins deux valeurs de pente différentes suivant sa longueur de telle manière que le mobile d'affichage puisse être entrainé en rotation suivant deux valeurs de pas différentes pour un même angle de rotation de la came en fonction de l'orientation de cette dernière en référence au palpeur.According to a first preferred embodiment, the actuating mechanism may comprise a cam against which a feeler is arranged in support, the feeler being kinematically linked to the mobile display, the cam having at least two different slope values along its length in such a way that the mobile display can be driven in rotation according to two different pitch values for the same angle of rotation of the cam as a function of the orientation of the latter with reference to the feeler.

Selon un deuxième mode de réalisation préféré, le mécanisme d'actionnement peut comporter des première et deuxième roues partenaires d'un engrenage non-circulaire ou une première roue partenaire d'un engrenage non-circulaire, le mobile d'affichage comprenant une deuxième roue partenaire de l'engrenage non-circulaire, les première et deuxième roues partenaires étant agencées de telle manière qu'elles engrènent l'une avec l'autre avec un rapport d'engrenage variable, le mobile d'affichage étant entrainé suivant au moins deux pas différents.According to a second preferred embodiment, the actuation mechanism may comprise first and second partner wheels of a non-circular gear or a first partner wheel of a non-circular gear, the display mobile comprising a second wheel partner of the non-circular gear, the first and second partner wheels being arranged in such a way that they mesh with each other with a variable gear ratio, the display mobile being driven in at least two different pitches.

Selon un troisième mode de réalisation préféré, le mobile d'affichage comporte une denture présentant au moins deux pas différents et agencé pour coopérer, d'une part, avec un mobile d'actionnement du mécanisme d'actionnement et, d'autre part, avec un sautoir pour assurer le maintien de la position et/ou de l'orientation de l'organe d'affichage, la denture étant indexée sur la position de l'échelle indicatrice.According to a third preferred embodiment, the display mobile comprises a toothing having at least two different pitches and arranged to cooperate, on the one hand, with an actuating mobile of the actuating mechanism and, on the other hand, with a jumper to maintain the position and/or the orientation of the display member, the teeth being indexed to the position of the indicator scale.

Dans ce cas, le mobile d'actionnement et le sautoir sont préférablement agencés de telle manière que le mobile d'actionnement actionne l'une des dents avec lesquelles le sautoir coopère, pour déplacer l'organe d'affichage.In this case, the actuating wheel set and the jumper are preferably arranged in such a way that the actuating wheel set actuates one of the teeth with which the jumper cooperates, to move the display member.

En outre, on peut prévoir que la denture présente au moins trois pas différents.In addition, provision can be made for the toothing to have at least three different pitches.

Dans une variante de réalisation particulière, on peut prévoir que la denture soit conformée de telle manière que sa dent la plus large présente une largeur inférieure au double de la largeur de sa dent la moins large.In a particular variant embodiment, provision may be made for the toothing to be shaped in such a way that its widest tooth has a width less than twice the width of its narrowest tooth.

De manière générale, on peut prévoir que les indications indiquent le quantième et/ou éventuellement qu'elles présentent trois largeurs différentes.In general, provision can be made for the indications to indicate the date and/or possibly for them to have three different widths.

Brève description des dessinsBrief description of the drawings

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée d'un mode de réalisation préféré qui suit, faite en référence aux dessins annexés donnés à titre d'exemple non limitatif et dans lesquels:

  • les figures 1a et 1b représentent une même vue de face simplifiée d'un affichage d'une pièce d'horlogerie respectivement selon l'état de la technique et selon un mode de réalisation préféré de la présente invention,
  • les figure 2a et 2b représentent des vues de face simplifiées d'une partie d'un mécanisme d'affichage en position de repos selon un mode de réalisation préféré de la présente invention, respectivement avec et sans disque d'affichage, et
  • la figure 3 représente le même mécanisme, dans une vue similaire à celle de la figure 2b, lors d'un changement de quantième.
Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description of a preferred embodiment which follows, made with reference to the appended drawings given by way of non-limiting example and in which:
  • them figures 1a and 1b represent the same simplified front view of a display of a timepiece respectively according to the state of the art and according to a preferred embodiment of the present invention,
  • them figure 2a and 2b show simplified front views of part of a display mechanism in the rest position according to a preferred embodiment of the present invention, respectively with and without a display disc, and
  • the figure 3 represents the same mechanism, in a view similar to that of the figure 2b , when changing the date.

Mode(s) de réalisation de l'inventionEmbodiment(s) of the Invention

Les figures 1a et 1b représentent une vue simplifiée d'un affichage d'une pièce d'horlogerie, respectivement selon l'état de la technique et selon la présente invention.The figures 1a and 1b represent a simplified view of a display of a timepiece, respectively according to the state of the art and according to the present invention.

Plus précisément, la figure 1a représente un compteur de quantième 106 selon l'état de la technique, destiné à être intégré dans un cadran d'une pièce d'horlogerie. Ladite pièce d'horlogerie comporte notamment un mécanisme d'affichage du quantième agencé pour afficher la valeur du quantième en commandant les déplacements d'une aiguille 102 en regard d'indications 104 disposées le long d'une échelle indicatrice 105, dans le compteur de quantième 106.More specifically, the picture 1a represents a date counter 106 according to the state of the art, intended to be integrated into a dial of a timepiece. Said timepiece comprises in particular a date display mechanism arranged to display the value of the date by controlling the movements of a hand 102 opposite indications 104 arranged along an indicator scale 105, in the counter of date 106.

Un examen visuel des indications 104 permet de constater qu'elles présentent différentes largeurs, ce qui est flagrant lorsque l'on compare notamment les indications relatives aux unités avec celles relatives aux dizaines, avec celles relatives aux vingtaines ou encore avec celle relative aux trentaines.A visual examination of the indications 104 shows that they have different widths, which is obvious when comparing in particular the indications relating to the units with those relating to the tens, with those relating to the twenties or even with that relating to the thirties.

Typiquement, l'aiguille 102 est portée par un mobile de quantième (non visible) entrainé par un doigt (non visible) pour avancer d'au moins un pas par jour, le doigt étant lui-même entrainé par un mobile de vingt-quatre heures (non visible). Un tel agencement permet à l'aiguille 102 d'avancer à pas constant (sans considérer ici le cas d'un mécanisme de quantième annuel ou perpétuel qui permettrait à l'aiguille 102 d'avancer de plusieurs pas d'affilé en fins de mois de moins de trente-et-un jours).Typically, the hand 102 is carried by a calendar wheel (not visible) driven by a finger (not visible) to advance at least one step per day, the finger itself being driven by a mobile of twenty-four hours (not visible). Such an arrangement allows the hand 102 to advance at a constant pitch (without considering here the case of an annual or perpetual calendar mechanism which would allow the hand 102 to advance several steps in a row at the end of the month less than thirty-one days).

Les différentes indications 104 sont séparées par des espaces de séparation 112. On constate que les espaces de séparation 112 ne présentent pas la même largeur entre deux indications 104 associées aux unités et entre deux indications 104 associées aux vingtaines, par exemple. Cette caractéristique conventionnelle est en effet destinée à assurer que le pas séparant deux indications 104 successives soit le même tout au long de l'échelle indicatrice 105, afin que les positions des indications 104 soient correctement associées aux différentes positions que peut occuper l'aiguille 102 du fait de son mode d'entrainement standard.The different indications 104 are separated by separation spaces 112. It can be seen that the separation spaces 112 do not have the same width between two indications 104 associated with the units and between two indications 104 associated with the scores, for example. This conventional feature is in fact intended to ensure that the pitch separating two successive indications 104 is the same all along the indicating scale 105, so that the positions of the indications 104 are correctly associated with the different positions that the needle 102 can occupy due to its standard drive mode.

Un tel affichage présente donc une différence notable dans la présentation des valeurs du quantième entre le début et la fin de l'échelle indicatrice, ce qui peut ne pas convenir à tout le monde d'un point de vue esthétique et diminue quelque peu la lisibilité dans les régions de l'échelle où les indications 104 sont plus proches les unes des autres. Bien entendu, si la question esthétique est également présente sur un affichage agencé à la périphérie du cadran, contrairement à la question de la lisibilité, ces deux aspects deviennent plus frappants à mesure que la surface de l'affichage concerné diminue.Such a display therefore presents a notable difference in the presentation of the date values between the start and the end of the indicator scale, which may not be suitable for everyone from an aesthetic point of view and somewhat reduces readability. in the regions of the scale where the indications 104 are closer together. Of course, if the aesthetic question is also present on a display arranged on the periphery of the dial, unlike the question of readability, these two aspects become more striking as the surface of the display concerned decreases.

Dans l'ensemble de la description le terme « largeur » désigne la dimension de l'indication dans la direction dans laquelle s'étend l'échelle indicatrice, parallèlement ou tangentiellement à l'échelle indicatrice selon qu'elle s'étend de manière rectiligne ou curviligne. Dans le mode de réalisation présenté, l'échelle indicatrice est circulaire sur une amplitude de 360° et la largeur d'une indication est sa dimension selon une direction ortho radiale. Cette dimension peut s'exprimer sous la forme d'une distance ou d'un angle dans le cas d'une échelle curviligne. De la même façon, les espaces de séparation représentent une dimension mesurée dans la direction où s'étend l'échelle indicatrice de sorte que, la longueur ou l'amplitude angulaire de l'échelle indicatrice est la somme des largeurs des indications et des espaces de séparation.Throughout the description, the term "width" designates the dimension of the indication in the direction in which the indicator scale extends, parallel or tangential to the indicator scale depending on whether it extends rectilinearly or curvilinear. In the embodiment shown, the indicator scale is circular over an amplitude of 360° and the width of an indication is its dimension in an ortho radial direction. This dimension can be expressed in the form of a distance or an angle in the case of a curvilinear scale. Similarly, the separating spaces represent a dimension measured in the direction in which the indicating scale extends so that the length or angular amplitude of the indicating scale is the sum of the widths of the indications and the spaces of seperation.

La figure 1b représente un compteur de quantième 6 selon l'invention, destiné à être intégré dans un cadran d'une pièce d'horlogerie. Selon un mode de réalisation préféré de la présente invention, ladite pièce d'horlogerie comporte notamment un mécanisme d'affichage du quantième agencé pour afficher la valeur du quantième en commandant les déplacements d'une aiguille 2 en regard d'indications 4 disposées le long d'une échelle indicatrice 5 dans le compteur 6.The figure 1b represents a date counter 6 according to the invention, intended to be integrated into a dial of a timepiece. According to a preferred embodiment of the present invention, said timepiece comprises in particular a date display mechanism arranged to display the value of the date by controlling the movements of a hand 2 facing indications 4 arranged along of an indicator scale 5 in the meter 6.

Les indications 4 présentent également différentes largeurs, comme c'est le cas avec les indications de l'état de la technique.The indications 4 also have different widths, as is the case with the indications of the state of the art.

On constate que les espaces de séparation 12 présentent cette fois tous sensiblement la même largeur, que cela soit entre deux indications 4 associées aux unités ou entre deux indications 4 associées aux vingtaines, par exemple. On obtient ainsi une perception plus agréable à l'œil, du fait de la régularité des alternances entre les indications 4 et les espaces de séparation 12 et on constate également que la lisibilité est augmentée en référence aux affichages de l'état de la technique, plus particulièrement au niveau des valeurs des vingtaines.It can be seen that the separation spaces 12 this time all have substantially the same width, whether this is between two indications 4 associated with the units or between two indications 4 associated with the twenties, for example. A perception that is more pleasing to the eye is thus obtained, due to the regularity of the alternations between the indications 4 and the separation spaces 12 and it is also noted that the readability is increased with reference to the displays of the state of the art, more particularly at the level of the values of the twenties.

Il ressort de ce qui précède que, pour passer d'une indication 4 à la suivante, l'aiguille 2 doit se déplacer suivant une certaine valeur de pas, cette valeur étant fonction de la largeur des indications 4 concernées, de manière à correspondre au positionnement angulaire irrégulier des indications le long de l'échelle indicatrice. Ainsi, cette valeur de pas sera par exemple plus faible entre deux indications 4 associées à des unités du quantième qu'entre deux indications 4 associées à des vingtaines du quantième.It emerges from the foregoing that, to pass from one indication 4 to the next, the hand 2 must move along a certain pitch value, this value being a function of the width of the indications 4 concerned, so as to correspond to the irregular angular positioning of indications along the indicating scale. Thus, this pitch value will for example be smaller between two indications 4 associated with units of the date than between two indications 4 associated with twenties of the date.

Pour permettre un tel agencement des indications 4, la présente invention prévoit préférablement que le mécanisme d'affichage comporte un mobile d'affichage agencé pour commander les déplacements de l'aiguille d'affichage 2, et un mécanisme d'actionnement agencé pour coopérer avec le mobile d'affichage et le déplacer suivant différentes positions successives associées aux indications 4, de telle manière que les différentes positions successives présentent entre elles au moins deux pas différents.To allow such an arrangement of the indications 4, the present invention preferably provides that the display mechanism comprises a mobile display arranged to control the movements of the display hand 2, and an actuating mechanism arranged to cooperate with the mobile display and move it according to different successive positions associated with the indications 4, in such a way that the different successive positions have between them at least two different pitches.

Différentes constructions sont envisageables pour le mécanisme d'affichage pour que l'aiguille 2 puisse se déplacer de telle manière que ses différentes positions successives présentent entre elles au moins deux pas différents.Different constructions can be envisaged for the display mechanism so that the hand 2 can move in such a way that its different successive positions have between them at least two different pitches.

A titre d'exemple illustratif non limitatif, le mécanisme d'actionnement peut comporter une came contre laquelle un palpeur est agencé en appui, le palpeur étant lié cinématiquement au mobile d'affichage, la came présentant au moins deux valeurs de pente différentes suivant sa longueur de telle manière que le mobile d'affichage puisse être entrainé en rotation suivant deux valeurs de pas différentes pour un même angle de rotation de la came en fonction de l'orientation de cette dernière en référence au palpeur.By way of non-limiting illustrative example, the actuating mechanism may include a cam against which a feeler is arranged to rest, the feeler being kinematically linked to the mobile display, the cam having at least two different slope values depending on its length in such a way that the mobile display can be driven in rotation according to two different pitch values for the same angle of rotation of the cam according to the orientation of the latter with reference to the probe.

En alternative, on peut prévoir que le mécanisme d'actionnement comporte des première et deuxième roues partenaires d'un engrenage non-circulaire ou une première roue partenaire d'un engrenage non-circulaire, le mobile d'affichage comprenant une deuxième roue partenaire de l'engrenage non-circulaire, les première et deuxième roues partenaires étant agencées de telle manière qu'elles engrènent l'une avec l'autre avec un rapport d'engrenage variable, le mobile d'affichage étant entrainé suivant au moins deux pas différents. Par engrenage non-circulaire, il faut comprendre, de manière conventionnelle, qu'il s'agit d'un engrenage entre deux roues partenaires présentant une région de contact dont la position, en référence aux centres de rotation des roues partenaires, dépend de l'orientation angulaire des roues partenaires.Alternatively, provision may be made for the actuation mechanism to comprise first and second partner wheels of a non-circular gear or a first partner wheel of a non-circular gear, the display mobile comprising a second partner wheel of the non-circular gear, the first and second partner wheels being arranged such that they mesh with each other with a variable gear ratio, the display mobile being driven in at least two different pitches . By non-circular gear, it should be understood, conventionally, that it is a gear between two partner wheels having a contact region whose position, with reference to the centers of rotation of the partner wheels, depends on the angular orientation of the partner wheels.

Selon une variante de réalisation supplémentaire, illustrée partiellement et de manière simplifiée sur les figures 2a, 2b et 3, on prévoit avantageusement que le mobile d'affichage comporte une denture 14 présentant au moins deux pas différents et agencée pour coopérer, d'une part, avec un mobile d'actionnement 16 du mécanisme d'actionnement et, d'autre part, avec un sautoir 18 pour positionner et maintenir le mobile d'affichage, la denture étant indexée sur la position de l'échelle indicatrice 5.According to an additional variant embodiment, illustrated partially and in a simplified manner on the figure 2a , 2b and 3 , it is advantageously provided that the mobile display comprises a set of teeth 14 having at least two different pitches and arranged to cooperate, on the one hand, with an actuating mobile 16 of the actuating mechanism and, on the other hand, with a jumper 18 to position and hold the display mobile, the teeth being indexed to the position of the indicator scale 5.

Le mécanisme d'affichage partiellement illustré sur les figures est destiné à afficher le quantième perpétuel et son fonctionnement ne sera pas intégralement décrit ici dans la mesure où le principe de base est déjà présenté dans le brevet EP 3026504 B1 , au nom de la Demanderesse. L'organe d'affichage 2 est une aiguille qui pointe sur une indication de quantième du compteur 6 en étant solidaire du mobile d'affichage.The display mechanism partially illustrated in the figures is intended to display the perpetual calendar and its operation will not be fully described here insofar as the basic principle is already presented in the patent EP 3026504 B1 , on behalf of the Claimant. Display member 2 is a hand which points to a date indication of counter 6 while being integral with the display mobile.

Le mobile d'actionnement 16 présente ici la forme d'une bascule d'actionnement, à titre illustratif non limitatif, celle-ci étant pivotée suivant un axe de rotation X1 en référence au bâti du mouvement horloger.The actuating mobile 16 here has the form of an actuating rocker, by way of non-limiting illustration, the latter being pivoted along an axis of rotation X1 with reference to the frame of the watch movement.

La bascule d'actionnement comprend un bras 20 destiné à recevoir des impulsions à partir d'un mobile d'entrainement (non visible) du mouvement horloger pour faire pivoter la bascule d'actionnement, dans le sens de rotation horaire, et entrainer en rotation le mobile d'affichage.The actuating rocker comprises an arm 20 intended to receive impulses from a drive mobile (not visible) of the movement watchmaker to rotate the actuating rocker, in the clockwise direction, and rotate the mobile display.

Dans ce but, la bascule d'actionnement porte un double-bec 22 comprenant des première et deuxième dents 24 et 26 agencées pour coopérer avec la denture 14 comme décrit dans le brevet antérieur mentionné plus haut. La bascule d'actionnement coopère notamment avec une came de quarante-huit 28, au moyen d'un palpeur 30, la came de quarante-huit 28 comprenant quarante-huit encoches de différentes profondeurs et dont chacune correspond à un mois donné parmi les quarante-huit mois d'un cycle bissextile.For this purpose, the actuating rocker carries a double jaw 22 comprising first and second teeth 24 and 26 arranged to cooperate with the toothing 14 as described in the prior patent mentioned above. The actuating rocker cooperates in particular with a forty-eight cam 28, by means of a sensor 30, the forty-eight cam 28 comprising forty-eight notches of different depths and each of which corresponds to a given month among the forty -eight months of a leap cycle.

Comme on peut le voir sur la figure 3, la première dent 24 agit sur la denture 14 lors du passage d'un jour au suivant jusqu'au dernier jour d'un mois donné. La deuxième dent 26 est destinée à agir sur un évidement 32 adapté, ménagé dans la denture 14, pour faire passer le quantième de la valeur du dernier jour d'un mois donné au premier jour du mois suivant lorsque le mois en cours compte moins de trente-et-un jours. L'information relative au nombre de jours du mois en cours est lue sur la came de quarante-huit 28 par insertion du palpeur 30 dans une encoche donnée, ce qui définit la position de départ de la bascule d'actionnement et donc son amplitude de pivotement, comme exposé dans le brevet antérieur précité.As can be seen on the picture 3 , the first tooth 24 acts on the toothing 14 during the transition from one day to the next until the last day of a given month. The second tooth 26 is intended to act on a suitable recess 32, provided in the toothing 14, to cause the date to pass from the value of the last day of a given month to the first day of the following month when the current month has fewer than thirty-one days. The information relating to the number of days of the current month is read on the forty-eight cam 28 by inserting the feeler 30 into a given notch, which defines the starting position of the actuating rocker and therefore its amplitude of pivoting, as disclosed in the aforementioned prior patent.

Le double-bec 22 est porté par la bascule d'actionnement par l'intermédiaire d'une liaison pivot associée à un ressort 34 de manière à former un cliquet, escamotable lors du retour de la bascule d'actionnement.The double jaw 22 is carried by the actuating rocker by means of a pivot connection associated with a spring 34 so as to form a pawl, retractable when the actuating rocker returns.

Un organe de positionnement double 36 assure le maintien des positions angulaires respectives de la came de quarante-huit 28 et de la bascule d'actionnement lorsqu'elles ne sont pas entrainées en rotation.A double positioning member 36 maintains the respective angular positions of the forty-eight cam 28 and of the actuating rocker when they are not rotated.

On notera également la présence de deux butées de limitation 38 de part et d'autre du bras 20 pour éviter que la bascule d'actionnement puisse quitter sa position de service.Note also the presence of two limit stops 38 on either side of the arm 20 to prevent the actuating rocker from leaving its operating position.

Le mécanisme d'affichage selon la présente invention se distingue de l'art antérieur par le fait que l'aiguille 2 se déplace suivant des pas variables le long de l'échelle indicatrice 5. En dehors d'autres constructions possibles comme celles mentionnées plus haut, il est possible de réaliser un entraînement adapté de l'aiguille 2 en réalisant une denture 14 présentant des dents de largeur variable.The display mechanism according to the present invention is distinguished from the prior art by the fact that the needle 2 moves according to variable pitches along the indicator scale 5. Apart from other possible constructions such as those mentioned above high, it is possible to make a adapted drive of the needle 2 by producing a set of teeth 14 having teeth of variable width.

L'aiguille de quantième 2 est positionnée en regard de l'indication 4 correspondant au premier du mois dans la configuration illustrée sur les figures 2a, 2b et 3. La position angulaire du mobile d'affichage est déterminée par les deux dents de la denture 14 qui coopèrent avec le sautoir 18.The date hand 2 is positioned opposite the indication 4 corresponding to the first of the month in the configuration illustrated on the figure 2a , 2b and 3 . The angular position of the mobile display is determined by the two teeth of the toothing 14 which cooperate with the jumper 18.

Un examen minutieux de la denture 14 permet de constater qu'une première série de dents 141, associée aux unités de quantième, présente une première largeur et est suivie d'une deuxième série de dents 142, associée aux dizaines de quantième, présentant une largeur légèrement supérieure à celle des dents 141 de la première série, la deuxième série étant suivie d'une troisième série de dents 143, associée aux vingtaines de quantième, dont la largeur est très légèrement supérieure à celle des dents 142 de la deuxième série, la troisième série étant enfin suivie de deux dents 144 pour les trentaines de quantième de largeur sensiblement identique à celle des dents 143 de la troisième série.A careful examination of the toothing 14 shows that a first series of teeth 141, associated with the date units, has a first width and is followed by a second series of teeth 142, associated with the tens of the date, having a width slightly greater than that of the teeth 141 of the first series, the second series being followed by a third series of teeth 143, associated with the date twenties, the width of which is very slightly greater than that of the teeth 142 of the second series, the third series being finally followed by two teeth 144 for the thirties of the date with a width substantially identical to that of the teeth 143 of the third series.

Ainsi, lorsque la bascule d'actionnement reçoit une impulsion, sa première dent 24 exerce une pression sur la dent de la denture 14 située immédiatement en amont du sautoir 18 pour faire tourner le mobile d'affichage, comme cela est illustré sur la figure 3. Dans la configuration présentée, il est important que le sautoir 18 soit situé à proximité de la dent de la denture 14 destinée à être entrainée par la première dent 24 afin que la dent destinée à être entrainée soit bien dans la trajectoire de la première dent 24. En effet le rôle du sautoir est non seulement d'assurer le maintien et le positionnement du mobile d'affichage en référence à l'échelle indicatrice 5 mais aussi de positionner la denture 14 en référence au mobile d'actionnement 16.Thus, when the actuating rocker receives an impulse, its first tooth 24 exerts pressure on the tooth of the gearing 14 located immediately upstream of the jumper 18 to rotate the display mobile, as illustrated in the picture 3 . In the configuration presented, it is important that the jumper 18 is located close to the tooth of the gearing 14 intended to be driven by the first tooth 24 so that the tooth intended to be driven is indeed in the trajectory of the first tooth 24 In fact, the role of the jumper is not only to hold and position the display mobile with reference to the indicator scale 5 but also to position the toothing 14 with reference to the actuating mobile 16.

Alternativement, il est possible, notamment pour faciliter la construction et réduire l'encombrement, de placer le sautoir à un autre emplacement en prévoyant que le mobile d'affichage comporte deux dentures distinctes, une première denture coopérant avec le sautoir, et une seconde denture coopérant avec le mobile d'entrainement. Les première et seconde dentures présentent des séquences de variations de pas angulaire identiques mais ont une orientation angulaire et/ou des rayons différents. On note que, dans le cas d'une denture avec des dents symétriques, il est préférable que la denture 14 soit conformée de telle manière que sa dent la plus large présente une largeur inférieure au double de la largeur de sa dent la moins large. Une telle limitation n'est pas nécessaire dans le cas d'une denture asymétrique.Alternatively, it is possible, in particular to facilitate construction and reduce bulk, to place the jumper at another location by providing that the mobile display has two separate teeth, a first toothing cooperating with the jumper, and a second toothing cooperating with the mobile drive. The first and second teeth have sequences of identical angular pitch variations but have different angular orientation and/or radii. It is noted that, in the case of a set of teeth with symmetrical teeth, it is preferable for the set of teeth 14 to be shaped in such a way that its widest tooth has a width less than twice the width of its narrowest tooth. Such a limitation is not necessary in the case of asymmetrical toothing.

Ce principe de fonctionnement à pas variable ne modifie pas la nature de l'action de la deuxième dent 26 de la bascule d'actionnement sur la denture 14, en fin de mois courts, par rapport à ce qui a été décrit dans le brevet antérieur cité plus haut.This variable-pitch operating principle does not modify the nature of the action of the second tooth 26 of the actuating rocker on the toothing 14, at the end of short months, compared to what was described in the prior patent. quoted above.

De même, la denture 14 présente une dent 141' de longueur supérieure à celle des autres dents de manière à ce qu'elle puisse coopérer avec la came de quarante-huit 28 une fois par mois pour la faire avancer d'un mois au suivant.Similarly, the toothing 14 has a tooth 141 'of greater length than that of the other teeth so that it can cooperate with the forty-eight cam 28 once a month to advance it from one month to the next. .

Grâce aux caractéristiques qui viennent d'être présentées, on obtient un mécanisme d'affichage qualitatif offrant une excellente lisibilité et qui peut être facilement adapté à un mécanisme existant.Thanks to the characteristics which have just been presented, a qualitative display mechanism is obtained offering excellent readability and which can be easily adapted to an existing mechanism.

La mise en œuvre de la présente invention n'est pas limitée à l'affichage du quantième. En effet, l'homme du métier ne rencontrera aucune difficulté particulière pour adapter le présent enseignement à la mise en œuvre d'un mécanisme d'affichage d'une autre grandeur que le quantième, qu'elle soit affichée par des nombres, des mots ou encore par des symboles de largeur variable, comme par exemple les phases de la Lune.The implementation of the present invention is not limited to the display of the date. Indeed, the person skilled in the art will not encounter any particular difficulty in adapting the present teaching to the implementation of a display mechanism of a magnitude other than the date, whether it is displayed by numbers, words or even by symbols of variable width, such as the phases of the Moon, for example.

La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple la construction du mécanisme d'actionnement telle que décrite et illustrée. En effet, comme mentionné plus haut, la divulgation qui précède permet à l'homme du métier de réaliser une grande variété de mécanismes d'affichage, comprenant des indications de largeur variable et des espaces de séparation entre elles, tous sensiblement de même largeur, en fonction de ses propres besoins, sans aucune difficulté et, de ce fait, sans sortir du cadre de la présente invention.The foregoing description sets out to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular characteristics which have just been described, such as for example the construction of the actuating mechanism as described and illustrated. Indeed, as mentioned above, the foregoing disclosure allows those skilled in the art to produce a wide variety of display mechanisms, comprising indications of variable width and separation spaces between them, all substantially of the same width, according to its own needs, without any difficulty and, therefore, without departing from the scope of the present invention.

Enfin, on notera également que, suivant le type de construction mis en œuvre, l'homme du métier pourra réaliser un affichage trainant ou sautant en fonction de ses propres besoins.Finally, it will also be noted that, depending on the type of construction implemented, the person skilled in the art will be able to produce a dragging or jumping display according to his own needs.
