Il existe donc un risque de casse du calendrier lors du réglage de la pièce d'horlogerie.The drive member may be in the form of a rigid finger, such as that disclosed, for example, by the figure 11 of the patent application EP2015146 . Such a finger, however, may oppose a calendar related correction mechanism if said finger is disposed in the teeth of the calendar disk. There is therefore a risk of breakage of the calendar when adjusting the timepiece.

L'organe d'entraînement peut également se présenter sous la forme d'un doigt élastique comme celui divulgué, par exemple, dans la demande de brevet EP3173878 . Un tel doigt est conformé pour d'une part entraîner de manière instantanée un disque de calendrier et, d'autre part, pour arrêter le disque de calendrier une fois le saut de date effectué, et ce afin d'obvier à tout risque de double saut de date. Ainsi, ce doigt fait également office de butée en venant s'opposer à une dent de la denture du disque de calendrier. Dans le cas, notamment, d'un calendrier annuel ou perpétuel, l'énergie accumulée par le mobile entraîneur de calendrier peut être telle que le doigt entraîneur élastique risque d'être escamoté sous l'effet du disque de calendrier un fois le saut de date effectué.The drive member may also be in the form of an elastic finger such as that disclosed, for example, in the patent application EP3173878 . Such a finger is shaped to firstly drive a calendar disk instantaneously and, secondly, to stop the calendar disk once the date jump is made, and this in order to obviate at any risk of double date jump. Thus, this finger also serves as a stop coming to oppose a tooth of the teeth of the calendar disc. In the case, in particular, of an annual or perpetual calendar, the energy accumulated by the mobile trainer calendar may be such that the elastic drive finger may be retracted under the effect of the calendar disc once the jump of date done.

On connaît du document FR1467726 un mobile d'entraînement doté d'un organe d'entraînement élastique. Celui-ci se présente sous la forme d'un ressort encastré sur une roue de calendrier, dont une extrémité se présente sous la forme d'un doigt d'entraînement. Le ressort est armé graduellement sous l'effet d'une dent d'un disque de calendrier jusqu'à ce que le doigt vienne buter à l'encontre d'une surface de butée, ce qui provoque le saut de date. Un tel mobile ne permet pas un saut de date parfaitement instantané du fait de l'armage graduel du ressort, ce qui induit un léger décalage angulaire du disque de calendrier avant le saut de date. Par ailleurs, le doigt risque d'être escamoté sous l'effet du disque de calendrier une fois le saut de date effectué. Il peut donc subsister un risque de double saut de date. Dans cette construction, le contact entre le doigt venu de matière avec le ressort et la surface de butée est ponctuel, dans le but de proposer un mobile entraîneur de calendrier alternatif au mobile entraîneur à came.Document is known FR1467726 a driving wheel with an elastic drive member. This is in the form of a recessed spring on a calendar wheel, one end of which is in the form of a drive finger. The spring is gradually cocked by a tooth of a calendar disc until the finger abuts against a stop surface, causing the date jump. Such a mobile does not allow a perfectly instantaneous date jump due to the gradual arming of the spring, which causes a slight angular offset of the calendar disc before the date jump. Moreover, the finger may be retracted under the effect of the calendar disc after the date jump. There may therefore be a risk of double jump dates. In this construction, the contact between the finger integrally with the spring and the abutment surface is punctual, in order to provide an alternating calendar driving mobile to the cam follower.

Le document CH711851 concerne un mobile d'entraînement similaire à celui du brevet FR1467726 . On reconnaît un doigt entraîneur venu de matière d'un ressort encastré à une roue. Un flanc du doigt est susceptible de venir en contact ponctuel à l'encontre d'une butée afin de déclencher le saut de date. Ce document concerne, plus particulièrement, une optimisation de la géométrie du doigt de façon à permettre le réglage rapide du calendrier lorsque le doigt est positionné au sein de la denture d'une étoile de calendrier.The document CH711851 relates to a training mobile similar to that of the patent FR1467726 . We recognize a driving finger come from material of a recessed spring to a wheel. A flank of the finger is likely to come into specific contact against a stop in order to trigger the date jump. This document relates, more particularly, an optimization of the geometry of the finger so as to allow quick adjustment of the calendar when the finger is positioned within the toothing of a calendar star.

Le document EP2428855 divulgue un mobile d'entraînement à came doté d'un organe d'entraînement pivotant constitué d'un pivot, d'un ressort de rappel et d'un doigt d'entraînement sur trois niveaux distincts. Si un tel mobile remplit les fonctions d'entraînement et d'arrêt du disque de calendrier, tout en permettant un réglage rapide du calendrier en tout temps, aussi bien dans le sens chronologique qu'anti-chronologique, il nécessite de mettre un volume conséquent à disposition pour répartir les différentes fonctions de l'organe d'entraînement.The document EP2428855 discloses a cam drive with a pivoting drive member consisting of a pivot, a return spring and a drive finger on three distinct levels. If such a mobile performs the functions of training and stopping the calendar disc, while allowing a quick adjustment of the calendar at any time, both chronologically and chronologically, it requires putting a large volume available to distribute the various functions of the drive member.

Le système de calendrier comprend un dispositif 100 d'entraînement.The calendar system includes a training device 100.

Le dispositif d'entraînement comprend un mobile 10 d'entraînement de l'élément 4 à entraîner, notamment le disque de calendrier 4. Le mobile d'entraînement est destiné à être monté à rotation autour d'un axe A1. Le mobile comprend :

  • un support 11 ;
  • un premier flanc f11 d'entraînement de l'élément à entraîner ; et

le mobile comprenant une liaison glissière 111, 121 liant le deuxième flanc au support.The driving device comprises a mobile 10 for driving the element 4 to be driven, in particular the calendar disk 4. The driving mobile is intended to be rotatably mounted about an axis A1. The mobile includes:
  • a support 11;
  • a first driving flank f11 of the element to be driven; and
  • a second flank f12 'arranged to receive a retraction action of the drive wheel, in particular a second retraction flank f12' extending orthoradially or substantially orthoradially with respect to the axis A1;
the mobile comprising a slide connection 111, 121 linking the second side to the support.

Avantageusement, la liaison glissière est orientée radialement ou sensiblement radialement relativement à l'axe A1.Advantageously, the slide connection is oriented radially or substantially radially relative to the axis A1.

L'élément à entraîner ne fait pas partie du dispositif d'entraînement.The element to be driven is not part of the training device.

Le premier flanc peut être constitué par une première surface plane ou sensiblement plane ou incurvée. Le deuxième flanc peut être constitué par une deuxième surface plane ou sensiblement plane ou incurvée.The first sidewall may be constituted by a first flat surface or substantially flat or curved. The second sidewall may be constituted by a second flat or substantially flat or curved surface.

Le premier flanc peut s'étendre radialement ou sensiblement radialement relativement à l'axe A1. Avantageusement, le premier flanc s'étend aussi parallèlement ou sensiblement parallèlement à l'axe A1. De préférence, le premier flanc est fixe ou sensiblement fixe angulairement autour de l'axe A1 par rapport au support.The first sidewall may extend radially or substantially radially relative to the axis A1. Advantageously, the first sidewall also extends parallel or substantially parallel to the axis A1. Preferably, the first flank is fixed or substantially angularly fixed around the axis A1 relative to the support.

Le deuxième flanc est agencé de sorte à recevoir une action d'escamotage du mobile, notamment à recevoir une action mécanique d'escamotage du mobile, l'action étant produite par l'élément à entraîner lorsque le mobile 10 se trouve dans une position interférant avec l'élément à entraîner.The second sidewall is arranged so as to receive a retraction action of the mobile, in particular to receive a mechanical action of retraction of the mobile, the action being produced by the element to be driven when the mobile 10 is in an interfering position with the element to train.

De préférence, le deuxième flanc s'étend orthoradialement ou sensiblement orthoradialement relativement à l'axe A1. Le deuxième flanc peut s'étendre en formant un angle inférieur à 30° avec la direction orthoradiale à l'axe A1. Avantageusement, le deuxième flanc s'étend aussi parallèlement ou sensiblement parallèlement à l'axe A1.Preferably, the second flank extends orthoradially or substantially orthoradially relative to the axis A1. The second sidewall may extend at an angle of less than 30 ° to the orthoradial direction to the axis A1. Advantageously, the second side also extends parallel or substantially parallel to the axis A1.

Ainsi, le dispositif comprend un premier organe rigide 11, notamment le support, incluant le premier flanc f11 d'entraînement et un deuxième organe élastique 12 incluant le deuxième flanc f12', qui sont prévus pour coopérer ensemble. De préférence, le deuxième organe 12 comprend encore un troisième flanc f12 de butée agencé pour arrêter l'élément à entraîner. Avantageusement, une telle réalisation permet un entraînement fiable du disque de calendrier grâce au premier organe d'entraînement, notamment grâce au premier flanc f11 du premier organe d'entraînement, ainsi qu'une correction en tout temps du calendrier grâce au deuxième organe élastique, notamment grâce au deuxième flanc f12' du deuxième organe élastique 12. En outre, une telle réalisation permet un arrêt fiable du disque de calendrier grâce au deuxième organe élastique 12, notamment grâce au troisième flanc f12 de butée de l'organe élastique 12. Avantageusement, cette structure de dispositif d'entraînement présente les avantages d'être compacte et simple à mettre en oeuvre.Thus, the device comprises a first rigid member 11, including the support, including the first flank f11 drive and a second elastic member 12 including the second flank f12 ', which are provided to cooperate together. Preferably, the second member 12 further comprises a third stop flank f12 arranged to stop the element to be driven. Advantageously, such an embodiment allows a reliable drive of the calendar disk thanks to the first drive member, in particular thanks to the first flank f11 of the first drive member, as well as a correction at any time of the calendar by means of the second elastic member, in particular by virtue of the second sidewall f12 'of the second elastic member 12. In addition, such an embodiment makes it possible to reliably stop the calendar disc by virtue of the second elastic member 12, in particular thanks to the third end flank f12 of the elastic member 12. Advantageously , this drive device structure has the advantages of being compact and simple to implement.

Dans ce premier mode de réalisation, le premier organe rigide 11 et le deuxième organe élastique 12 du mobile d'entraînement 10 sont disposés dans un même plan ou sur un même niveau P1.In this first embodiment, the first rigid member 11 and the second elastic member 12 of the driving wheel 10 are arranged in the same plane or on the same level P1.

Ces premier et deuxième organes 11 et 12 font tous deux partie d'un organe d'entraînement 1 pivoté selon un axe A1 relativement à un moyen de guidage du bâti du mouvement non représenté sur les figures. L'organe d'entraînement fait partie du dispositif d'entraînement.These first and second members 11 and 12 are both part of a drive member 1 pivoted along an axis A1 relative to a guide means of the frame of the movement not shown in the figures. The driving member is part of the driving device.

L'organe d'entraînement 1 présente ici une forme de noyau tubulaire dont au moins une portion est prévue pour réceptionner les premier et deuxième organes 11, 12. Le premier organe rigide 11 peut être venu de matière avec l'organe 1. Celui-ci prend ici la forme d'une protrusion de matière faisant saillie de l'organe 1 selon l'axe A1, c'est-à-dire une saillie s'étendant longitudinalement à l'axe A1. Cette saillie s'étend également notamment selon une direction radiale ou sensiblement radiale relativement à l'axe A1.The drive member 1 here has a tubular core shape of which at least a portion is provided for receiving the first and second members 11, 12. The first rigid member 11 may be integral with the member 1. This here takes the form of a protrusion of material protruding from the member 1 along the axis A1, that is to say a projection extending longitudinally to the axis A1. This projection also extends in particular in a radial direction or substantially radial relative to the axis A1.

Le deuxième organe élastique 12 est, quant à lui, rapporté sur l'organe 1. Le deuxième organe élastique 12 est un élément de rappel élastique, comme un ressort, dont une première extrémité présente une tête 12a, et dont une deuxième extrémité présente un pied 12b encastré ou fixé rigidement à l'organe 1, notamment par des rivets. Ainsi, la première extrémité présente le deuxième flanc. La deuxième extrémité présente quant à elle une fixation au support. La tête 12a et le pied 12b sont reliés par une partie élastique formant un ressort courbé 12c. La tête 12a est préférentiellement en contact avec l'organe rigide 11. Préférentiellement, les organes 11 et 12 sont conformés de telle façon que la tête 12a présente un seul et unique degré de liberté de déplacement (aux jeux près) selon une direction radiale ou sensiblement radiale relativement à l'axe A1. Le ressort courbé 12c constitue un élément 12c de rappel élastique rappelant le deuxième organe 12 et le deuxième flanc f12' vers une position de repos, comme illustré sur les figures 1, 2 et 5 à 9. Le ressort 12c a par exemple une forme d'anneau ouvert.The second elastic member 12 is, in turn, attached to the member 1. The second elastic member 12 is an elastic return member, such as a spring, a first end has a head 12a, and a second end has a foot 12b recessed or rigidly fixed to the member 1, in particular by rivets. Thus, the first end has the second flank. The second end has a fixation to the support. The head 12a and the foot 12b are connected by an elastic portion forming a curved spring 12c. The head 12a is preferably in contact with the rigid member 11. Preferably, the members 11 and 12 are shaped such that the head 12a has a single and unique degree of freedom of movement (with the games close) in a radial direction or substantially radial relative to the axis A1. The curved spring 12c constitutes an element 12c of elastic return reminding the second member 12 and the second flank f12 'towards a rest position, as illustrated in the figures 1 , 2 and 5 to 9 . The spring 12c has for example an open ring shape.

Par exemple, la liaison glissière liant le deuxième flanc au support comprend une première face 121 réalisée sur l'élément portant le deuxième flanc, notamment la tête 12a et une deuxième face 111 réalisée sur le support 11. Les faces 111 et 121 sont de préférence planes et/ou les faces 111 et 121 s'étendent préférentiellement radialement ou sensiblement radialement relativement à l'axe A1. Avantageusement, les faces 111 et 121 s'étendent aussi parallèlement ou sensiblement parallèlement à l'axe A1. De préférence, un élément de rappel élastique, notamment le ressort 12c, est conformé et/ou agencé de sorte à rappeler les faces 111 et 121 l'une contre l'autre.For example, the slide connection linking the second sidewall to the support comprises a first face 121 made on the element carrying the second side, in particular the head 12a and a second face 111 made on the support 11. The faces 111 and 121 are preferably planes and / or the faces 111 and 121 preferably extend radially or substantially radially relative to the axis A1. Advantageously, the faces 111 and 121 also extend parallel or substantially parallel to the axis A1. Preferably, an elastic return element, in particular the spring 12c, is shaped and / or arranged so as to recall the faces 111 and 121 against each other.

Dans ce premier mode de réalisation, le deuxième flanc peut être déplacé relativement au premier flanc selon la liaison glissière contre l'action de l'élément de rappel élastique.In this first embodiment, the second sidewall can be moved relative to the first side according to the sliding connection against the action of the elastic return element.

L'organe d'entraînement 1 est solidaire d'une came 2, notamment une came de calendrier, coopérant avec un accumulateur d'énergie 3, afin que cet organe puisse entraîner instantanément, d'un pas angulaire au moins, la denture du disque 4 d'affichage des quantièmes, qui est indexée angulairement par le biais d'un bec 51 d'un sautoir 5. De préférence, le support 11 est solidaire de la came 2 de calendrier.The drive member 1 is integral with a cam 2, in particular a calendar cam cooperating with an energy accumulator 3, so that this member can drive instantly, at least an angular pitch, the toothing of the disc 4 of date display, which is indexed angularly through a spout 51 of a jumper 5. Preferably, the support 11 is secured to the cam 2 calendar.

L'accumulateur d'énergie est ici constitué d'une bascule 3 munie d'un galet 31 appliqué contre le flanc de la came 2 sous l'effet d'une portion 3a de bascule formant ressort, et permet, lors du passage de date, de vaincre le couple produit par le sautoir 5.The energy accumulator here consists of a rocker 3 provided with a roller 31 applied against the side of the cam 2 under the effect of a portion 3a of spring rocker, and allows, during the passage of date , to overcome the couple produced by the jumper 5.

Le mobile 10 comprend, par ailleurs, une roue 6, pivotée librement selon l'axe A1 autour de l'organe 1, qui est reliée à un mouvement de base, notamment à une roue des heures non représentée sur les figures afin que le saut de date puisse être effectué une fois par jour à minuit. La liaison entre l'organe d'entraînement 1 et la roue 6 s'effectue par le biais d'un dispositif 7 de liaison unidirectionnelle, dont le principe de fonctionnement est décrit dans le document EP2428855 .The mobile 10 further comprises a wheel 6, freely rotated along the axis A1 around the member 1, which is connected to a base movement, in particular to a wheel hours not shown in the figures so that the jump can be done once a day at midnight. The connection between the drive member 1 and the wheel 6 is effected by means of a unidirectional connecting device 7, the operating principle of which is described in the document EP2428855 .

Ce dispositif 7 comporte un organe 71 d'encliquetage et un ressort 72 qui sont tous deux pivotés sur un plateau 73 chassé sur l'organe 1. Le ressort 72, prenant appui contre une extrémité de l'organe 71, tend à maintenir l'extrémité opposée de cet organe 71 contre une paroi 73a du plateau 73. Cet organe 71 est entraîné par la roue 6 de manière unidirectionnelle en coopérant par obstacle avec un plot 6a faisant saillie de la planche de la roue 6.This device 7 comprises a locking member 71 and a spring 72 which are both pivoted on a plate 73 driven on the member 1. The spring 72, bearing against one end of the member 71, tends to maintain the opposite end of this member 71 against a wall 73a of the plate 73. This member 71 is driven by the wheel 6 in a unidirectional manner cooperating by obstacle with a stud 6a projecting from the plate of the wheel 6.

Ce dispositif 7 comprend la roue de 24 heures 6 qui est en prise avec la roue des heures ou roue à canon (non représentée) du rouage de la pièce d'horlogerie. Le rapport d'engrenage entre la roue de 24 heures 6 et la roue des heures est tel que la roue de 24 heures 6 fait un tour en 24 heures. Cette roue pivote librement autour d'un premier segment du noyau tubulaire 1 monté pivotant sur un pivot solidaire d'un bâti de la pièce d'horlogerie.This device 7 comprises the 24-hour wheel 6 which is engaged with the hour wheel or barrel wheel (not shown) of the wheel of the timepiece. The gear ratio between the 24 hour wheel 6 and the hour wheel is such that the 24 hour wheel 6 makes one turn in 24 hours. This wheel pivots freely around a first segment of the tubular core 1 pivotally mounted on a pivot integral with a frame of the timepiece.

Un évidement circulaire comprenant la paroi 73a est ménagé dans le plateau 73. L'organe d'encliquetage 71 est monté pivotant à l'aide d'un pivot dans l'évidement. Le ressort 72, prenant appui contre une extrémité de l'organe d'encliquetage 71, tend à maintenir l'extrémité opposée de cet organe d'encliquetage 71 contre la paroi latérale de l'évidement circulaire. Cet organe d'encliquetage 71 sert d'organe d'entraînement unidirectionnel entre la roue de 24 heures 6 et le plateau 73 qui est solidaire de l'organe 1.A circular recess including the wall 73a is provided in the plate 73. The latching member 71 is pivotally mounted with a pivot in the recess. The spring 72, bearing against one end of the detent member 71, tends to keep the opposite end of the detent member 71 against the side wall of the circular recess. This locking member 71 serves as unidirectional drive member between the 24-hour wheel 6 and the plate 73 which is integral with the member 1.

Le noyau tubulaire 1 comporte encore un deuxième segment de diamètre réduit par rapport au premier segment sur lequel pivote la roue de 24 heures 6 et qui s'étend au-dessous de cette roue de 24 heures 6. La came 2 de saut instantané est chassée sur le deuxième segment du noyau tubulaire 1 et peut prendre appui contre une portée ménagée entre les premier et deuxième segments par l'intermédiaire du plateau 73 lui-même chassé sur ledit deuxième segment du noyau tubulaire 1.The tubular core 1 further comprises a second reduced diameter segment with respect to the first segment on which the 24 hour wheel 6 pivots and which extends below this 24 hour wheel 6. The instantaneous jump cam 2 is driven out on the second segment of the tubular core 1 and can bear against a span formed between the first and second segments through the plate 73 itself driven on said second segment of the tubular core 1.

La came de saut instantané 2 est en prise avec le galet 31 porté par la bascule 3 qui est pressée contre la came 2 par le ressort 3a. Cette came 2 comporte au moins une surface d'armage, une surface de saut instantané et une surface d'arrêt, notamment une surface d'arrêt concave. L'intersection entre les deux surfaces d'armage et de saut instantané détermine l'instant exact où la bascule 3 sollicitée par le ressort 3a va faire brusquement passer le galet 31 de cette intersection à la surface d'arrêt.The instantaneous jump cam 2 is engaged with the roller 31 carried by the rocker 3 which is pressed against the cam 2 by the spring 3a. This cam 2 comprises at least one arming surface, an instantaneous jump surface and a stop surface, in particular a concave stop surface. The intersection between the two surfaces of arming and instantaneous jump determines the exact moment when the rocker 3 solicited by the spring 3a will make abruptly pass the roller 31 of this intersection to the stop surface.

Les figures 1 à 4 illustrent les caractéristiques précitées en détail. Dans un souci de clarté, les figures 5 à 9, qui détaillent le séquencement d'un saut instantané de date, ainsi que des phases de réglage rapide de la date, ne représentent ni la roue 6, ni le dispositif 7 de liaison unidirectionnelle.The Figures 1 to 4 illustrate the above-mentioned features in detail. For the sake of clarity, Figures 5 to 9 , which detail the sequencing of an instantaneous jump of date, as well as phases of rapid adjustment of the date, represent neither the wheel 6, nor the device 7 unidirectional connection.

Tout au long de la journée, la roue 6 mène une came 2 par le biais du dispositif 7 et accumule l'énergie nécessaire au saut instantané de l'organe 1, c'est-à-dire l'énergie nécessaire à la rotation sur une plage angulaire prédéterminée de l'organe 1, en armant la portion élastique 3a d'un ressort par l'intermédiaire d'un galet 31 et du profil de la came 2. Juste avant le passage de date (illustré sur les figures 4 et 5), le galet 31 est disposé sensiblement au sommet du profil de la came 2. Le passage de date (illustré sur la figure 6) s'effectue en une fraction de seconde lorsque la portion ressort 3a restitue l'énergie accumulée en communiquant un mouvement brusque de rotation à la came 2 et à l'organe 1 par l'intermédiaire de la bascule 3 et de son galet 31. Ce mouvement relatif entre les éléments 1, 2 et la roue 6 est rendu possible grâce au degré de liberté offert par le dispositif 7 de liaison unidirectionnelle.Throughout the day, the wheel 6 leads a cam 2 through the device 7 and accumulates the energy required for the instantaneous jump of the member 1, that is to say the energy required for rotation on a predetermined angular range of the member 1, by arming the elastic portion 3a of a spring via a roller 31 and the profile of the cam 2. Just before the date shift (shown on the figures 4 and 5 ), the roller 31 is disposed substantially at the top of the profile of the cam 2. The passage of date (shown on the figure 6 ) is performed in a fraction of a second when the spring portion 3a restores the accumulated energy by communicating a sudden rotational movement to the cam 2 and to the member 1 via the rocker 3 and its roller 31. This relative movement between the elements 1, 2 and the wheel 6 is made possible thanks to the degree of freedom offered by the unidirectional connecting device 7.

De préférence, le premier organe rigide 11 constitue avantageusement un doigt d'entraînement de calendrier, et comporte un flanc f11 qui est prévu pour venir en contact direct avec une dent 4a du disque 4, comme représenté sur la figure 6. Ainsi, du fait de la rigidité du premier organe, l'organe d'entraînement 1 ne subit pas de déformation parasite lors de l'entraînement du disque, et transmet ainsi au disque 4 une force F orthoradiale ou sensiblement orthoradiale relativement à l'axe A1, et dont l'orientation est constante ou sensiblement constante en regard de la dent 4a. Lors de cette séquence de fonctionnement, l'organe élastique 12 est sans effet sur le disque.Preferably, the first rigid member 11 advantageously constitutes a calendar drive finger, and has a flank f11 which is provided to come into direct contact with a tooth 4a of the disc 4, as shown in FIG. figure 6 . Thus, because of the rigidity of the first member, the drive member 1 does not undergo spurious deformation during drive of the disk, and thus transmits to the disk 4 a force F orthoradial or substantially orthoradial relative to the axis A1, and whose orientation is constant or substantially constant with respect to the tooth 4a. During this sequence of operation, the elastic member 12 has no effect on the disc.

Une fois le saut de date réalisé (comme illustré figure 7), le disque 4 est freiné par l'organe 1 par l'intermédiaire d'une dent 4b jouxtant la dent 4a, qui vient buter à l'encontre du troisième flanc de butée f12 de la tête 12a du deuxième organe élastique 12, lui-même en butée ou susceptible de venir en butée à l'encontre du premier organe rigide 11, sous l'effet d'une force de réaction F' orthoradiale ou sensiblement orthoradiale relativement à l'axe A1. Lors de cette séquence de fonctionnement, le ressort 12c du deuxième organe élastique 12 est sans effet. Ainsi, l'organe 1 ne subit pas de déformation parasite lors du freinage du disque lorsque les éléments 11 et 12a sont disposés au sein de la denture du disque 4, entre deux dents 4a, 4b.Once the date jump is done (as shown figure 7 ), the disk 4 is braked by the member 1 via a tooth 4b adjacent the tooth 4a, which abuts against the third abutment flange f12 of the head 12a of the second elastic member 12, he even in abutment or capable of coming into abutment against the first rigid member 11, under the effect of a reaction force F 'orthoradial or substantially orthoradial relative to the axis A1. During this sequence of operation, the spring 12c of the second elastic member 12 has no effect. Thus, the member 1 does not undergo spurious deformation during braking of the disc when the elements 11 and 12a are disposed within the toothing of the disc 4, between two teeth 4a, 4b.

Ainsi, le troisième flanc f12 est un flanc de freinage ou de butée de l'élément 4 à entraîner. De préférence, ce troisième flanc s'étend radialement ou sensiblement radialement relativement à l'axe A1. Avantageusement, le troisième flanc s'étend aussi parallèlement ou sensiblement parallèlement à l'axe A1. Le troisième flanc est de préférence fixe ou sensiblement fixe angulairement autour de l'axe A1 par rapport au support.Thus, the third flank f12 is a brake or abutment flank of the element 4 to be driven. Preferably, this third flank extends radially or substantially radially relative to the axis A1. Advantageously, the third flank also extends parallel or substantially parallel to the axis A1. The third sidewall is preferably fixed or substantially angularly fixed around the axis A1 relative to the support.

Dans la configuration de la figure 7, le premier organe 11 et le deuxième organe 12, notamment la tête 12a, sont maintenus en position sous l'effet d'une force prédéfinie et établie par la portion ressort 3a de la bascule 3, qui maintient le galet 31 dans un creux défini par le profil de la came 2.In the configuration of the figure 7 , the first member 11 and the second member 12, in particular the head 12a, are held in position under the effect of a predefined force and established by the spring portion 3a of the lever 3, which holds the roller 31 in a defined recess by the profile of the cam 2.

Avant le saut de date (illustré sur la figure 5), les organes 11 et 12a sont hors de portée de la denture du disque 4. Il est donc possible de procéder à une correction rapide de la date, que ce soit en sens chronologique ou anti-chronologique, par un actionnement de la denture du disque 4 grâce, par exemple, à une étoile 8 de correction prenant part à un mécanisme de correction connexe activable à la demande.Before the date jump (shown on the figure 5 ), the members 11 and 12a are out of range of the toothing of the disc 4. It is therefore possible to proceed to a rapid correction of the date, whether chronologically or chronologically, by actuating the teeth of the disk 4 by, for example, a star 8 correction taking part in a related correction mechanism activatable on demand.

Après le saut de date, les organes 11 et 12a sont maintenus dans la denture sous l'effet d'une force prédéfinie et établie par la portion ressort 3a de la bascule 3, qui maintient le galet 31 dans un creux défini par le profil de la came 2. Une correction rapide de la date en sens chronologique comme illustré sur la figure 8 est néanmoins possible grâce au dispositif de liaison unidirectionnelle 7 qui permet de découpler les éléments 1 et 2 de la roue 6.After the date jump, the members 11 and 12a are held in the toothing under the effect of a predefined force and established by the spring portion 3a of the lever 3, which holds the roller 31 in a recess defined by the profile of the cam 2. A quick correction of the date in chronological sense as shown on the figure 8 is nevertheless possible thanks to the unidirectional connecting device 7 which allows to decouple the elements 1 and 2 of the wheel 6.

Le premier organe 11 présente ici la particularité d'être conformé et/ou agencé de façon à être hors de portée de la denture du disque 4 une fois le saut de date effectué comme représenté sur la figure 9. Ainsi, une correction rapide de la date en sens anti-chronologique comme illustré sur la figure 9 est tout à fait possible grâce à l'escamotage de la tête 12a sous l'effet de la dent 4a repoussant le flanc f12' en déformant élastiquement le ressort 12c. La force d'action F" de la dent 4a sur le flanc f12' de la tête 12a est ici radiale ou sensiblement radiale relativement à l'axe A1. La tête 12a et le flanc f12' que la tête constitue sont écartés de la position de repos illustrée sur les figures 1, 2 et 5 à 9. Dans cette configuration, la tête 12a présente ici la particularité d'être conformée et/ou agencée de sorte que seul son flanc f12' soit à la portée de la dent 4a. Une fois la correction effectuée, le ressort courbé 12c rappelle élastiquement le deuxième organe 12 et le deuxième flanc f12' vers une position de repos, comme illustré sur les figures 1, 2 et 5 à 9.The first member 11 here has the particularity of being shaped and / or arranged so as to be out of reach of the toothing of the disk 4 once the date jump is performed as shown in FIG. figure 9 . So, a quick correction of the date in anti-chronological direction as shown on the figure 9 is quite possible thanks to the retraction of the head 12a under the effect of the tooth 4a pushing the flank f12 'elastically deforming the spring 12c. The action force F "of the tooth 4a on the flank f12 'of the head 12a is here radial or substantially radial relative to the axis A1. The head 12a and the flank f12' that the head constitutes are separated from the position of rest illustrated on figures 1 , 2 and 5 to 9 . In this configuration, the head 12a here has the particularity of being shaped and / or arranged so that only its side f12 'is within range of the tooth 4a. Once the correction is made, the curved spring 12c resiliently recalls the second member 12 and the second flank f12 'towards a rest position, as illustrated in FIGS. figures 1 , 2 and 5 to 9 .

Ainsi, le deuxième flanc est de préférence un flanc d'escamotage du mobile, en particulier d'escamotage de la tête 12a du deuxième organe.Thus, the second sidewall is preferably a retraction side of the mobile, in particular retraction of the head 12a of the second member.

Dans le premier mode de réalisation, le premier flanc est fixe relativement au support ou le premier flanc est solidaire du support.In the first embodiment, the first sidewall is fixed relative to the support or the first sidewall is integral with the support.

Un deuxième mode de réalisation est décrit ci-après en référence aux figures 10 à 12. Ce deuxième mode de réalisation diffère du premier mode de réalisation en ce que le deuxième flanc est solidaire du premier flanc, c'est-à-dire que les premier et deuxième flancs sont fixes l'un par rapport à l'autre et/ou diffère du premier mode de réalisation par la réalisation de la liaison glissière.A second embodiment is described below with reference to Figures 10 to 12 . This second embodiment differs from the first embodiment in that the second sidewall is secured to the first sidewall, that is to say that the first and second sides are fixed relative to each other and / or differs from the first embodiment by producing the slide connection.

Dans une première variante du deuxième mode de réalisation représentée sur la figure 10, la liaison glissière comprend une rainure 120 réalisée sur un élément portant le deuxième flanc, notamment réalisée dans la tête 12a du deuxième organe 12, et une goupille 11 réalisée sur le support, notamment une goupille encastrée dans le support. La rainure et la goupille sont agencées et conformées pour coopérer ensemble pour réaliser la liaison glissière. De préférence, la glissière est agencée de sorte que son axe de translation ou sensiblement de translation soit radial ou sensiblement radial à l'axe A1. En fonctionnement, il peut se produire un léger pivotement de la rainure autour de la goupille. Toutefois, ce pivotement reste tout-à-fait négligeable de sorte que la liaison est considérée comme une liaison glissière. Si besoin, la goupille peut être remplacée par une conformation non circulaire, notamment parallélépipédique, pour limiter ce pivotement.In a first variant of the second embodiment shown on the figure 10 , the slide connection comprises a groove 120 formed on an element carrying the second sidewall, in particular made in the head 12a of the second member 12, and a pin 11 made on the support, in particular a pin embedded in the support. The groove and the pin are arranged and shaped to cooperate together to achieve the slide connection. Preferably, the slideway is arranged so that its axis of translation or substantially of translation is radial or substantially radial to the axis A1. In operation, there may be a slight pivoting of the groove around the pin. However, this pivoting remains completely negligible so that the link is considered as a slide link. If necessary, the pin can be replaced by a non-circular conformation, including parallelepiped, to limit this pivoting.

Ainsi, dans cette première variante, la tête 12a du deuxième organe élastique peut constituer le doigt d'entraînement de calendrier. La goupille 11 peut être remplacée par un tenon 11 venu de matière de l'organe 1. En fonctionnement du calendrier, les parois de la rainure 120 sont prévues pour venir buter à l'encontre de la goupille ou du tenon.Thus, in this first variant, the head 12a of the second elastic member may constitute the calendar drive finger. The pin 11 may be replaced by a pin 11 integrally made of the member 1. In calendar operation, the walls of the groove 120 are provided to abut against the pin or the tenon.

La rainure peut se limiter à une découpe à une seule paroi.The groove may be limited to a single wall cut.

Dans une deuxième variante du deuxième mode de réalisation représentée sur les figures 11 et 12, la liaison glissière comprend une goupille 120' réalisée sur un élément portant le deuxième flanc, notamment une goupille encastrée dans la tête 12a du deuxième organe 12, et une rainure 110 réalisée sur le support. La rainure et la goupille sont agencées et conformées pour coopérer ensemble pour réaliser la liaison glissière. De préférence, la glissière est agencée de sorte que son axe de translation ou sensiblement de translation soit radial ou sensiblement radial à l'axe A1. En fonctionnement, il peut se produire un léger pivotement de la rainure autour de la goupille. Toutefois, ce pivotement reste tout-à-fait négligeable de sorte que la liaison est considérée comme une liaison glissière. Si besoin, la goupille peut être remplacée par une conformation non circulaire, notamment parallélépipédique, pour limiter ce pivotement.In a second variant of the second embodiment shown on the figures 11 and 12 , the slide connection comprises a pin 120 'made on a member carrying the second side, including a pin embedded in the head 12a of the second member 12, and a groove 110 formed on the support. The groove and the pin are arranged and shaped to cooperate together to make the slide connection. Preferably, the slideway is arranged so that its axis of translation or substantially of translation is radial or substantially radial to the axis A1. In operation, there may be a slight pivoting of the groove around the pin. However, this pivoting remains completely negligible so that the link is considered as a slide link. If necessary, the pin can be replaced by a non-circular conformation, in particular parallelepipedic, to limit this pivoting.

Dans cette deuxième variante, le premier organe rigide 11 et le deuxième organe élastique 12 sont disposés selon deux plans ou deux niveaux distincts. En effet, dans cette variante, le doigt d'entraînement et la liaison glissière sont réalisés sur deux plans perpendiculaires à l'axe A1 et différents. Le principe de fonctionnement du mobile 10 selon cette deuxième variante est similaire à celui selon la première variante.In this second variant, the first rigid member 11 and the second elastic member 12 are arranged in two planes or two distinct levels. Indeed, in this variant, the drive finger and the slide connection are made on two planes perpendicular to the axis A1 and different. The operating principle of the mobile 10 according to this second variant is similar to that according to the first variant.

Le deuxième organe élastique de cette variante peut présenter une forme semblable à celle du deuxième organe élastique de la première variante. Le tenon 120' venu de matière de la tête 12a ou la goupille 120' peuvent s'étendre selon un plan P2 de sorte à s'ébattre au sein de la découpe 110 creusée sur l'organe 11. Cette découpe peut présenter préférentiellement la forme d'une rainure dotée de deux parois distinctes, et ce de sorte à faire office de butée quelle que soit la phase de fonctionnement du calendrier. Bien entendu, cette découpe peut se limiter à présenter une seule paroi.The second elastic member of this variant may have a shape similar to that of the second elastic member of the first variant. The tenon 120 'made of material of the head 12a or the pin 120' can extend along a plane P2 so as to romp within the cutout 110 excavated on the member 11. This cutout may preferably have the shape a groove with two separate walls, and that to act as a stop regardless of the operating phase of the calendar. Of course, this cut can be limited to presenting a single wall.

Quel que soit le mode de réalisation, l'organe d'entraînement 1 peut par ailleurs comporter un doigt d'entraînement 13 additionnel prévu pour actionner une denture connexe non représentée à la fin d'un mois de moins de 31 jours. Préférentiellement, ce doigt 13 est disposé à un niveau ou sur un plan distinct de celui du doigt d'entraînement comprenant les organes 11 ou 12a.Whatever the embodiment, the drive member 1 may further comprise an additional drive finger 13 provided to actuate a not shown connected toothing at the end of a month of less than 31 days. Preferably, this finger 13 is disposed at a level or on a plane distinct from that of the driving finger comprising the members 11 or 12a.

Des modes de réalisation du dispositif d'entraînement ont été décrits précédemment appliqués à l'entraînement d'un élément de calendrier. Toutefois, un dispositif d'entraînement selon l'invention peut bien entendu être utilisé pour entraîner toute sorte d'élément permettant l'affichage ou l'indication d'une information horlogère, notamment une information d'heures et/ou une information de minutes. De préférence, l'affichage ou l'indication de l'information horlogère est du type sautant, en particulier sautant instantané.Embodiments of the training device have been described previously applied to the training of a calendar element. However, a drive device according to the invention can of course be used to drive any kind of element allowing the display or the indication of a watch information, including hour information and / or minute information. Preferably, the display or the indication of the clock information is of the jumping type, in particular jumping instantaneously.

Au contraire de ce qui est connu de l'art antérieur, dans les solutions selon l'invention, le deuxième organe élastique se distingue notamment par le fait que celui-ci n'est pas prévu pour être armé graduellement par le disque de calendrier afin d'activer un saut plus ou moins instantané de date, mais pour escamoter le mobile d'entraînement de la denture du calendrier lors d'une phase de réglage du calendrier. Dans les solutions selon l'invention, l'instantanéité du saut pourra, quant à elle, être garantie préférentiellement par une came 2 liée au, notamment solidaire du, support 11. Par ailleurs, le deuxième organe élastique se distingue par le fait qu'à une première extrémité, il est encastré sur le support et, à une deuxième extrémité, il est monté en liaison glissière relativement à ce support. Enfin, le doigt d'entraînement, par sa rigidité, permet de mener de la manière la plus continue qui soit le disque de calendrier. Ceci permet d'éviter toute saccade du disque de calendrier lors du saut instantané.In contrast to what is known from the prior art, in the solutions according to the invention, the second elastic member is distinguished in particular by the fact that it is not intended to be gradually armed by the calendar disk so to activate a jump more or less instantaneous date, but to retract the training mobile of the teeth of the calendar during a phase of adjustment of the calendar. In the solutions according to the invention, the instantaneity of the jump may, for its part, be preferably guaranteed by a cam 2 linked to, in particular, integral with the support 11. Furthermore, the second elastic member is distinguished by the fact that at a first end, it is recessed on the support and, at a second end, it is mounted in sliding connection relative to this support. Finally, the drive finger, by its rigidity, can lead in the most continuous way that is the calendar disc. This avoids any jerkiness of the calendar disk during the instantaneous jump.

Quel que soit le mode de réalisation, la liaison glissière est opérante aussi bien pour une correction en sens avant, que pour une correction en sens arrière.Whatever the embodiment, the slide connection is operative both for correction in the forward direction, as for a correction in the backward direction.

Quel que soit le mode de réalisation, le deuxième flanc f12' est exclusivement prévu pour recevoir une action d'escamotage, c'est-à-dire que le deuxième flanc et l'élément à entraîner sont agencés de préférence de sorte que l'élément à entraîner puisse agir exclusivement et/ou directement par contact sur le deuxième flanc pour l'escamoter. Le premier flanc f11 est exclusivement prévu pour entraîner l'élément à entraîner, c'est-à-dire que le premier flanc et l'élément à entraîner sont agencés de sorte que le premier flanc puisse agir exclusivement et/ou directement par contact sur l'élément à entraîner pour l'entraîner. Il y a donc une séparation des fonctions entre les deux flancs. Autrement dit, le premier flanc n'est pas utilisé pour escamoter le mobile d'entraînement et le deuxième flanc n'est pas utilisé pour entraîner l'élément à entraîner.Whatever the embodiment, the second flank f12 'is exclusively intended to receive a retraction action, that is to say that the second flank and the element to be driven are preferably arranged so that the element to be driven can act exclusively and / or directly by contact on the second side to retract it. The first flank f11 is exclusively intended to drive the element to be driven, that is to say that the first flank and the element to be driven are arranged of so that the first sidewall can act exclusively and / or directly by contact on the element to be driven to drive it. There is therefore a separation of functions between the two flanks. In other words, the first sidewall is not used to retract the drive wheel and the second sidewall is not used to drive the element to train.

Quel que soit le mode de réalisation, les premier et deuxième flancs sont distincts l'un de l'autre.Whatever the embodiment, the first and second flanks are distinct from each other.

Dans tout ce document, par « liaison glissière », on entend, de préférence, une liaison mécanique n'autorisant qu'un degré de liberté. Ce degré de liberté est une translation selon l'axe de la liaison glissière.Throughout this document, by "slide connection" is meant, preferably, a mechanical connection allowing only one degree of freedom. This degree of freedom is a translation along the axis of the slide link.

Dans tout ce document, par « escamotage du mobile d'entraînement », on entend, de préférence, l'escamotage d'un élément ou d'une partie du mobile d'entraînement, notamment l'escamotage d'une tête 12a du mobile d'entraînement.Throughout this document, by "retraction of the drive mobile" is preferably meant the retraction of an element or a portion of the drive mobile, including the retraction of a head 12a of the mobile drive.
