Correction is applied by an adjusting wheel (25). The hour wheel (1) and it's bushing (11) have radial elastic fingers (15) and guides (17) which allow the indicating disk and toothed wheel to be pushed past them and retained axially being free to rotate in response to the driving wheel Independent claims are also included for the following: (1) A timepiece mechanism wheel which has a bushing with radial outwardly directed elastic fingers to receive and locate axially an indicating wheel which is free to rotate in response to a separate drive; (2) A timepiece mechanism wheel which has elastic fingers directed radially inward to locate it axially on a central support while leaving it free to rotate in response to a separate drive.

Description

La présente invention concerne de manière générale le montage de mobiles coaxiaux, notamment le montage de disques indicateurs (par ex. des disques indicateurs des jours, des quantièmes, des mois ou analogues), dans des pièces d'horlogerie. La présente invention concerne plus particulièrement le montage de tels mobiles coaxiaux par leur centre sur un organe de support central, et notamment le montage d'un mobile coaxial sur un mobile de minuterie d'une pièce d'horlogerie.The present invention relates generally to the mounting of mobiles coaxial, in particular the mounting of indicator discs (e.g. discs day, date, month or similar indicators), in rooms watchmaking. The present invention relates more particularly to the mounting of such coaxial mobiles by their center on a central support member, and in particular the mounting of a coaxial mobile on a timer mobile of a timepiece.

Les mobiles coaxiaux tels les disques indicateurs montés par leur centre sont communément retenus axialement par un élément additionnel, à savoir un circlip engagé dans une gorge ménagée sur la périphérie de l'organe de support central sur lequel est monté le disque (typiquement un arbre, un axe ou le canon d'un mobile de minuterie). Ce circlip se présente communément sous la forme d'un anneau ouvert ou fermé présentant des caractéristiques élastiques permettant son insertion dans la gorge de l'organe de support central.Coaxial mobiles such as indicator discs mounted by their center are commonly retained axially by an additional element, namely a circlip engaged in a groove formed on the periphery of the central support member on which is mounted the disc (typically a shaft, an axis or the barrel of a mobile of timer). This circlip is commonly in the form of an open ring or closed with elastic characteristics allowing its insertion into the throat of the central support member.

Le document US 3,659,412 montre par exemple la fixation d'un disque indicateur sur le canon d'un mobile de minuterie (en l'occurrence une roue des heures) et sa retenue axiale au moyen de différents exemples de circlips ouverts ou fermés. A noter que le disque indicateur est typiquement solidaire d'une étoile collaborant avec un système d'entraínement adéquat et que la position angulaire du disque indicateur est indexée au moyen d'un ressort-sautoir venant se loger entre deux dents de l'étoile.Document US 3,659,412 shows for example the fixing of a disc indicator on the barrel of a timer mobile (in this case a wheel of hours) and its axial retention by means of different examples of open circlips or closed. Note that the indicator disc is typically attached to a star collaborating with an adequate drive system and that the angular position of the indicator disc is indexed by means of a jumper spring which fits between two teeth of the star.

On notera ainsi que la retenue axiale du disque indicateur sur son organe de support central est réalisée au moyen d'un élément additionnel qui renchérit les coûts de fabrication de la pièce d'horlogerie et implique une étape d'assemblage additionnelle consistant en l'introduction du circlip dans la gorge correspondante de l'organe de support central.It will thus be noted that the axial retention of the indicator disc on its member central support is achieved by means of an additional element which increases costs of manufacturing the timepiece and involves an assembly step additional consisting of the introduction of the circlip in the corresponding groove of the central support member.

Un but de la présente invention est de proposer une solution permettant de s'affranchir de l'utilisation d'un élément de retenue additionnel et en conséquence de réduire les coûts de fabrication et limiter le nombre d'étapes d'assemblage de la pièce d'horlogerie.An object of the present invention is to propose a solution making it possible to get rid of the use of an additional retaining element and consequently reduce manufacturing costs and limit the number of assembly steps for the part watchmaking.

La présente invention a ainsi pour premier objet un dispositif de fixation d'un mobile coaxial pour pièce d'horlogerie dont les caractéristiques sont énoncées dans la revendication indépendante 1, ainsi que dans la revendication indépendante 15. The present invention thus has for first object a device for fixing a coaxial mobile for a timepiece whose characteristics are set out in the independent claim 1, as well as in independent claim 15.

La présente invention a également pour objet un mobile de minuterie destiné à recevoir un mobile coaxial dont les caractéristiques sont énoncées dans la revendication indépendante 9.The present invention also relates to a timer mobile intended for receive a coaxial mobile whose characteristics are set out in the independent claim 9.

Des modes de réalisation avantageux de la présente invention font l'objet des revendications dépendantes.Advantageous embodiments of the present invention are the subject of dependent claims.

Selon l'invention, le mobile coaxial est ainsi retenu axialement sur son organe de support par l'intermédiaire d'une pluralité de doigts élastiques. De la sorte, on s'affranchit de la nécessité de prévoir un élément de retenue axiale additionnel pour maintenir le mobile coaxial sur l'organe de support. Ces doigts élastiques font préférablement partie intégrante de l'organe de support. Au titre d'alternative, ces doigts élastiques peuvent être ménagés sur le mobile coaxial lui-même.According to the invention, the coaxial mobile is thus retained axially on its member of support by means of a plurality of elastic fingers. In this way, we overcomes the need to provide an additional axial retaining element for maintain the coaxial mobile on the support member. These elastic fingers make preferably an integral part of the support member. As an alternative, these elastic fingers can be provided on the coaxial mobile itself.

L'assemblage du mobile coaxial sur son organe de support est par ailleurs très simple en ce sens qu'il suffit d'introduire le mobile sur l'organe de support parallèlement à son axe, la pluralité de doigts élastiques se déformant radialement au passage du mobile pour revenir ensuite en place est en assurer la retenue axiale.The assembly of the coaxial mobile on its support member is also very simple in the sense that it suffices to introduce the mobile on the support member parallel to its axis, the plurality of elastic fingers deforming radially at the passage of the mobile to return then in place is to ensure the axial retention.

D'autres caractéristiques et avantages de la présente invention apparaítront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation préféré de l'invention donné uniquement à titre d'exemple non limitatif et illustré par les dessins annexés où :

  • la figure 1 est une vue en coupe partielle, selon une ligne de coupe A-A, d'un mouvement d'une pièce d'horlogerie montrant un exemple de réalisation préféré d'un dispositif de fixation d'un disque indicateur des jours sur le canon d'une roue des heures ;
  • la figure 2 est une vue en plan partielle, côté cadran, du dispositif de fixation illustré dans la figure 1 ;
  • la figure 3a est une vue en coupe partielle, analogue à la vue en coupe de la figure 1, illustrant de manière détaillée le dispositif de fixation lors du montage du disque indicateur des jours sur le canon de la roue des heures ;
  • la figure 3b est analogue à la figure 3a et illustre le dispositif de fixation après montage du disque indicateur des jours sur le canon de la roue des heures ; et
  • les figures 4a et 4b sont deux vues isométriques, respectivement des parties supérieure et inférieure de la roue des heures à canon du mouvement des figures 1 à 3b.
Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description which follows of a preferred embodiment of the invention given solely by way of nonlimiting example and illustrated by the appended drawings where:
  • Figure 1 is a partial sectional view, along a section line AA, of a movement of a timepiece showing a preferred embodiment of a device for fixing a day indicator disc on the barrel an hour wheel;
  • Figure 2 is a partial plan view, dial side, of the fixing device illustrated in Figure 1;
  • Figure 3a is a partial sectional view, similar to the sectional view of Figure 1, illustrating in detail the fixing device during mounting of the day indicator disc on the barrel of the hour wheel;
  • Figure 3b is similar to Figure 3a and illustrates the fixing device after mounting the day indicator disc on the barrel of the hour wheel; and
  • Figures 4a and 4b are two isometric views, respectively of the upper and lower parts of the cannon hour wheel of the movement of Figures 1 to 3b.

Les figures montrent un mode de réalisation préféré d'un dispositif de fixation d'un mobile coaxial selon la présente invention. En l'occurrence, le dispositif de fixation illustré est destiné à assurer la fixation et la retenue d'un disque indicateur des jours, désigné globalement par la référence numérique 2, sur le canon 11 d'une roue des heures 1 d'un mouvement horloger.The figures show a preferred embodiment of a fixing device of a coaxial mobile according to the present invention. In this case, the fixing illustrated is intended to ensure the fixing and the retention of an indicator disc of the days, generally designated by the numerical reference 2, on the barrel 11 of a wheel 1 hours of a watch movement.

Le mouvement pour pièce d'horlogerie du type avec seconde au centre est visible en partie sur la coupe de la figure 1 et la vue en plan de la figure 2 (à noter que les coupes sont prises selon la ligne de coupe A-A reportée sur la figure 2). On y distingue notamment un pont de rouage 8 et une platine 9 définissant une cage dans laquelle se trouve l'essentiel du mouvement. On distingue en particulier un mobile de seconde 3 au centre, monté à pivot sur le pont de rouage 8, avec son axe de seconde 30, son pignon de seconde 31 et sa roue de seconde 32, une chaussée 4 disposée directement sur l'axe 30 du mobile de seconde 3 et une roue d'entraínement 42 montée à friction sur la chaussée 4. Cette roue d'entraínement 42 se trouve typiquement en prise avec un pignon de moyenne (non représenté) solidaire d'une roue moyenne (non représentée) qui engrène avec le pignon de seconde 31. La chaussée 4 transmet typiquement son mouvement de rotation à un mobile de minuterie (non représenté) qui engrène dans sa partie terminale, du côte cadran, avec la roue des heures 1 via son pignon de minuterie (non représenté). La face externe de la platine 9 comporte en outre un épaulement annulaire 91 servant de guide de positionnement radial à la roue des heures 1, elle-même pourvue dans sa base d'un évidement correspondant pour accueillir cet épaulement 91. On notera enfin que la roue des heures 1, montée libre à rotation sur la chaussée 4, intègre également un renvoi 12 d'une roue d'entraínement 5 actionnant un disque de quantième 6 à denture intérieure ainsi que le disque indicateur des jours 2.The movement for a timepiece of the type with a central second is partially visible in the section of FIG. 1 and the plan view of FIG. 2 (note that the sections are taken along the section line A-A shown in Figure 2). We distinguishes in particular a gear train 8 and a plate 9 defining a cage in which is the essence of the movement. There is in particular a mobile of second 3 in the center, pivotally mounted on the gear train 8, with its second axis 30, its second pinion 31 and its second wheel 32, a carriageway 4 arranged directly on the axis 30 of the second mobile 3 and a drive wheel 42 friction mounted on the roadway 4. This drive wheel 42 is located typically engaged with a medium pinion (not shown) secured to a medium wheel (not shown) which meshes with the second pinion 31. The pavement 4 typically transmits its rotational movement to a mobile timer (not shown) which meshes in its terminal part, on the dial side, with the hour wheel 1 via its timer pinion (not shown). The external face of the plate 9 further comprises an annular shoulder 91 serving as a guide radial positioning at the hour wheel 1, itself provided in its base with a corresponding recess to accommodate this shoulder 91. Finally, it will be noted that the hour wheel 1, freely mounted for rotation on the roadway 4, also incorporates a return 12 of a drive wheel 5 actuating a date disc 6 with teeth interior as well as the day indicator disc 2.

Le disque indicateur des jours 2 comporte quant à lui une étoile des jours 21 solidaire d'un disque 22 portant les inscriptions des jours de la semaine, inscriptions qui sont typiquement destinées à apparaítre successivement dans un guichet du cadran (non représenté). Par souci de clarté, le disque 22 n'est pas illustré dans la vue en plan de la figure 2, seul l'étoile des jours 21 étant représentée. Le disque indicateur des jours 2 est typiquement actionné tous les jours (une fois par 24 heures), aux environs de minuit, par l'intermédiaire de la roue d'entraínement 5 au moyen d'un doigt 51 qui lui est solidaire. Cette roue d'entraínement 5 est d'un type spécifique dont une plus ample description peut être trouvée dans le document EP 0 548 659, également au nom du présent Déposant.The day 2 indicator disc has a day star 21 attached to a disc 22 carrying the inscriptions of the days of the week, inscriptions which are typically intended to appear successively in a window of the dial (not shown). For the sake of clarity, the disc 22 is not illustrated in the plan view of FIG. 2, only the day star 21 being represented. The disc day indicator 2 is typically operated every day (once per 24 hours), around midnight, via the drive wheel 5 at by means of a finger 51 which is integral with it. This drive wheel 5 is of a type specific of which a further description can be found in the document EP 0 548 659, also on behalf of the present Applicant.

La position du disque indicateur des jours 2 peut en outre être corrigée par le biais d'un mécanisme de correction (typiquement entraíné par une tige-couronne). Une roue correctrice 25 faisant partie de ce mécanisme de correction est illustrée dans les figures 1 et 2. On notera également que la position angulaire du disque indicateur des jours 2 est indexée au moyen d'un ressort-sautoir 72 dont une partie apparaít sur la coupe de la figure 1. Ce ressort-sautoir 72 fait partie d'une plaque de maintien 7 qui est rendue solidaire de la platine 9 et qui intègre également, comme illustré dans la figure 2, un ressort-sautoir 76 pour l'indexation du disque de quantième 6.The position of the day 2 indicator disc can also be corrected by the through a correction mechanism (typically driven by a crown stem). A corrective wheel 25 forming part of this correction mechanism is illustrated in Figures 1 and 2. Note also that the angular position of the disc day indicator 2 is indexed by means of a jumper spring 72, part of which appears in the section of Figure 1. This jumper spring 72 is part of a plate holding 7 which is made integral with the plate 9 and which also incorporates, as illustrated in FIG. 2, a jumper spring 76 for indexing the disc of date 6.

On s'intéressera maintenant plus particulièrement à la structure de la roue des heures 1 et de son canon 11 qui constituent à proprement parler l'organe de support central du disque indicateur des jours 2 permettant d'en assurer la fixation et la retenue axiale. Les figures 3a et 3b montre des vues agrandies de la coupe de la figure 1, respectivement lors du montage et après le montage du disque indicateur 2 sur le canon 11 de la roue des heures 1. Les figures 4a et 4b montrent quant à elles des vues isométriques de cette roue des heures 1 et de son canon 11. Selon l'invention, le canon 11 de la roue des heures 1 porte ainsi une pluralité, ici trois, de doigts élastiques 15 s'étendant radialement vers l'extérieur du canon 11 et destinés à assurer un maintien axial du disque indicateur 2 sur le canon 11. Ces doigts élastiques 15 sont préférablement disposés symétriquement autour du canon 11 (dans cet exemple à 120° les uns des autres).We will now focus more specifically on the structure of the wheel of hours 1 and its barrel 11 which strictly speaking constitute the support member center of the day 2 indicator disc allowing it to be fixed and axial restraint. Figures 3a and 3b show enlarged views of the cross-section of the Figure 1, respectively during assembly and after assembly of the indicator disc 2 on the barrel 11 of the hour wheel 1. Figures 4a and 4b show isometric views of this hour wheel 1 and its barrel 11. According to the invention, the barrel 11 of the hour wheel 1 thus carries a plurality, here three, of elastic fingers 15 extending radially outwards from the barrel 11 and intended for ensure axial retention of the indicator disc 2 on the barrel 11. These fingers elastic bands 15 are preferably arranged symmetrically around the barrel 11 (in this example at 120 ° from each other).

Dans la configuration illustrée, les doigts élastiques 15 sont agencés pour se déformer de manière élastique vers l'intérieur du canon 11 pour permettre une insertion axiale du disque indicateur 2, par son orifice central de montage 2a, sur le canon 11 de la roue des heures 1. Les figures 3a et 3b permettent de mettre en évidence ce qui vient d'être mentionné. En effet, comme illustré dans la figure 3a, lors de l'insertion du disque indicateur 2, l'étoile des jours 21 entre en contact avec l'extrémité des doigts 15 de sorte qu'ils sont contraints à se déformer radialement vers l'axe de la roue des heures 1. Une fois le disque 2 inséré, comme illustré dans la figure 3b, les doigts 15 reviennent dans leur position de repos pour retenir axialement le disque 2 par son étoile des jours 21. Dans cette position, on comprendra bien évidemment que le disque indicateur 2 est libre en rotation autour du canon 11.In the illustrated configuration, the elastic fingers 15 are arranged to be deform elastically inward of the barrel 11 to allow a axial insertion of the indicator disc 2, through its central mounting hole 2a, on the canon 11 of the hour wheel 1. Figures 3a and 3b are used to highlight evidence what has just been mentioned. Indeed, as illustrated in Figure 3a, when of the insertion of the indicator disc 2, the day star 21 comes into contact with the end of the fingers 15 so that they are forced to deform radially towards the axis of the hour wheel 1. Once the disc 2 is inserted, as illustrated in the Figure 3b, the fingers 15 return to their rest position to retain axially disc 2 by its star of days 21. In this position, we will understand obviously that the indicator disc 2 is free to rotate around the barrel 11.

On comprendra encore que, lors du montage du disque indicateur 2 sur la roue des heures, il conviendra de veiller à ce que l'étoile des jours 21 engrène convenablement avec sa roue d'entraínement 5, sa roue correctrice 25 ainsi qu'avec l'extrémité du ressort-sautoir 72.It will also be understood that, during the mounting of the indicator disc 2 on the hour wheel, it will be necessary to ensure that the day star 21 meshes suitably with its drive wheel 5, its corrective wheel 25 as well as with the end of the jumper spring 72.

Comme illustré dans les figures, la configuration du canon 11 de la roue des heures 1, selon le mode de réalisation préféré, est telle que ce canon 11 présente une partie terminale 11 a destinée à l'introduction d'une aiguille des heures (non représentée), une première partie médiane 11 b où sont disposés les doigts élastiques 15, une seconde partie médiane 11c de diamètre sensiblement analogue (mais inférieur) au diamètre de l'orifice de montage 2a du disque indicateur des jours 2 et autour de laquelle repose radialement ce disque indicateur, et une portée 11d sur laquelle repose axialement le disque indicateur des jours 2 (cette portée 11 d est ici formée par la face du renvoi 12 de la roue de quantième).As illustrated in the figures, the configuration of the barrel 11 of the wheel of the hours 1, according to the preferred embodiment, is such that this barrel 11 has a end part 11 a intended for the introduction of an hour hand (not shown), a first middle portion 11 b where the elastic fingers are arranged 15, a second middle portion 11c of substantially similar diameter (but lower) than the diameter of the mounting hole 2a of the day 2 indicator disc and around which this indicator disc rests radially, and a bearing 11d on which axially rests the indicator disc for days 2 (this range 11 d is here formed by the face of the reference 12 of the date wheel).

Dans ce mode de réalisation préféré, on notera que la seconde partie médiane 11c accueillant le disque indicateur des jours 2 comporte une pluralité d'évidements radiaux 16, en nombre équivalent au nombre de doigts élastiques, ménagés dans des positions correspondant angulairement aux positions des doigts élastiques 15. De la sorte, une fois monté, le disque des jours 2 repose directement sur la seconde partie médiane 11 c, rigide, les doigts élastiques 15 revenant dans leur position de repos une fois le disque indicateur 2 inséré pour en assurer sa retenue axiale. On notera bien évidemment que les doigts élastiques 15 s'étendent radialement du canon 11 sur une distance légèrement supérieure au rayon correspondant de l'orifice de montage 2a du disque indicateur 2 de manière à assurer, en position de repos, la retenue axiale du disque 2. Ces doigts élastiques 15 doivent par ailleurs être suffisamment flexibles pour qu'ils se déforment lors de l'insertion du disque et permettent le passage de ce dernier.In this preferred embodiment, it will be noted that the second middle part 11c housing the day 2 indicator disc has a plurality of recesses radial 16, in a number equivalent to the number of elastic fingers, formed in positions angularly corresponding to the positions of the elastic fingers 15. From the so, once mounted, the 2 days disc rests directly on the second part middle 11 c, rigid, the elastic fingers 15 returning to their rest position a the indicator disc 2 inserted to ensure its axial retention. We will note well obviously that the elastic fingers 15 extend radially from the barrel 11 over a distance slightly greater than the corresponding radius of the mounting hole 2a of the indicator disc 2 so as to ensure, in the rest position, the axial retention of the disc 2. These elastic fingers 15 must moreover be sufficiently flexible so that they deform when the disc is inserted and allow the passage of this latest.

On notera que les évidements radiaux 16 se prolongent comme illustré vers la base de la roue des heures 1. En effet, la roue des heures, ou de manière générale l'organe de support central du disque indicateur, est préférablement réalisé en un matériau synthétique, tel un plastique. La configuration illustrée des évidements radiaux 16 permet à ce titre de simplifier la construction du moule de la roue des heures 1. On notera cependant que l'utilisation d'un matériau plastique n'est pas obligatoire, tout matériau présentant des caractéristiques élastiques suffisantes pour le but recherché pouvant être utilisé.It will be noted that the radial recesses 16 extend as illustrated towards the base of the hour wheel 1. Indeed, the hour wheel, or generally the central support member of the indicator disc, is preferably made in one synthetic material, such as plastic. The illustrated configuration of the recesses radials 16 makes it possible to simplify the construction of the mold of the wheel of the hours 1. Note, however, that the use of a plastic material is not compulsory, any material with sufficient elastic characteristics to the desired goal can be used.

On notera encore que la première partie médiane 11 b du canon 11 de la roue des heures 1 comporte en outre préférablement une pluralité de guides radiaux 17 (également au nombre de trois dans cet exemple) disposés entre les doigts élastiques 15 pour guider le disque indicateur 2 lors de son insertion sur la roue des heures 1. Ces guides 17 permettent d'assurer un bon positionnement radial du disque indicateur 2 lors de son insertion et protègent également les doigts élastiques 15 de la roue des heures de sorte qu'ils ne subissent qu'une déformation minime lors de l'insertion du disque indicateur 2. Préférablement, ces guides radiaux 17 sont ménagés de sorte qu'ils soient les premiers à entrer en contact avec le disque indicateur 2 lors de son insertion. Plus exactement, les guides radiaux 17 ainsi que les doigts élastiques 15 présentent, dans leur partie supérieure, un chanfrein dont l'angle diffère. En l'occurrence, l'angle du chanfrein pratiqué sur les guides radiaux 17 est moins important (par rapport à une perpendiculaire à l'axe d'insertion du disque indicateur) que l'angle du chanfrein pratiqué sur les doigts flexibles. De la sorte, le disque indicateur est tout d'abord guidé et centré sur l'axe par les guides 17 (cf. figure 3a) avant d'entrer effectivement en contact avec les doigts élastiques 15. D'autres configuration peuvent évidemment être envisagées. Les guides 17 peuvent ainsi simplement être placés plus en hauteur sur le canon 11 de la roue des heures 1.It will also be noted that the first middle part 11b of the barrel 11 of the wheel hours 1 further preferably comprises a plurality of radial guides 17 (also three in this example) arranged between the elastic fingers 15 to guide the indicator disc 2 when it is inserted on the hour wheel 1. These guides 17 ensure good radial positioning of the indicator disc 2 during its insertion and also protect the elastic fingers 15 of the wheel from hours so that they undergo only minimal deformation when inserting the indicator disc 2. Preferably, these radial guides 17 are arranged so they are the first to come into contact with the indicator disk 2 when it insertion. More precisely, the radial guides 17 as well as the elastic fingers 15 have, in their upper part, a chamfer whose angle differs. In the occurrence, the angle of the chamfer made on the radial guides 17 is less important (relative to a perpendicular to the axis of insertion of the indicator disc) than the angle of the chamfer on the flexible fingers. In this way, the disc indicator is first of all guided and centered on the axis by the guides 17 (cf. FIG. 3a) before actually coming into contact with the elastic fingers 15. Others configuration can obviously be considered. Guides 17 can thus simply be placed higher on the barrel 11 of the hour wheel 1.

On comprendra de manière générale que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. En particulier, la présente invention n'est pas limitée uniquement à la fixation d'un disque des jours et de son étoile sur le canon d'une roue des heures, mais s'applique de manière analogue pour permettre la fixation de tout autre mobile coaxial devant être monté sur un organe de support central tel un mobile de minuterie ou tout autre élément de support, que celui-ci soit fixe ou mobile. La solution décrite reste cependant particulièrement avantageuse pour l'application présentée plus haut.It will generally be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the mode of embodiment described in the present description without departing from the scope of the invention defined by the appended claims. In particular, the present invention is not limited only to the fixing of a disc of the days and its star on the barrel of a wheel hours, but applies analogously to allow the fixation of any other coaxial mobile to be mounted on a central support member such as a mobile timer or any other support element, whether fixed or mobile. The solution described remains particularly advantageous for the application presented above.

On notera par ailleurs que l'invention n'est pas limitée à la fixation d'un disque indicateur des jours, mais peut s'appliquer à tout autre type de disque indicateur monté par son centre sur un organe de support central, tel par exemple un disque des quantièmes, des mois, ou encore des phase de lune.Note also that the invention is not limited to the attachment of a disc day indicator, but may apply to any other type of indicator disc mounted by its center on a central support member, such as for example a disc of dates, months, or even moon phases.

Au titre d'alternative au mode de réalisation présenté plus haut, on notera encore qu'il est envisageable de ménager les doigts élastiques, non plus sur l'organe de support central, mais sur le mobile coaxial lui-même. Dans ce cas, la pluralité de doigts élastiques s'étendraient radialement vers l'intérieur du mobile coaxial (c'est-à-dire en direction de l'axe de rotation de l'ensemble), ces doigts élastiques étant similairement agencé pour se déformer de manière élastique pour permettre une insertion axiale du mobile coaxial sur l'organe de support central et pour revenir dans une position de repos afin d'assurer une retenue axiale du mobile coaxial.As an alternative to the embodiment presented above, it will be noted although it is possible to spare the elastic fingers, no longer on the organ central support, but on the coaxial mobile itself. In this case, the plurality of elastic fingers would extend radially inward from the coaxial mobile (i.e. towards the axis of rotation of the assembly), these elastic fingers being similarly arranged to deform elastically to allow a axial insertion of the coaxial mobile on the central support member and to return to a rest position to ensure axial retention of the coaxial mobile.
