Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

La demande EP18186552 , relative à un mécanisme d'affichage d'horlogerie à géométrie variable avec aiguille élastique, expose un premier mécanisme d'actionnement par le biais de mobiles avec dentures de forme. Une telle réalisation permet l'exécution d'affichages très innovants en horlogerie, et est toutefois coûteuse, et réservée à des pièces de luxe.Requirement EP18186552 , relating to a variable geometry clockwork display mechanism with elastic hand, discloses a first actuation mechanism by means of mobiles with shaped teeth. Such an embodiment allows the execution of very innovative displays in horology, and is however expensive, and reserved for luxury parts.

La même demande décrit encore un deuxième cas de mécanisme d'actionnement par le biais d'un premier différentiel sur le rouage du premier canon et un second différentiel sur le rouage du second canon, et au moins une came constituant une entrée d'un tel différentiel. Dès lors, il convient de trouver et de dimensionner un engrenage planétaire (différentiel) adéquat. Les engrenages planétaires ont l'avantage de réaliser des rapports de transmission importants sous un faible encombrement. Les arbres d'entrées et de sortie sont dans le prolongement l'un de l'autre. Les possibilités de combinaison d'engrenages sont très nombreuses. Elles permettent, en particulier, de réaliser d'intéressantes boîtes à vitesses. Dans le cas présent, il s'agit de piloter une des entrées du différentiel, de manière à générer une avance et respectivement un retard d'une valeur spécifique équivalente sur chacune des extrémités de l'aiguille. Et, lorsque cette valeur est nulle, il faut obtenir un rapport de transmission de 1 (la valeur positive signifie que le sens doit également être identique).The same application also describes a second case of an actuation mechanism by means of a first differential on the cog of the first barrel and a second differential on the cog of the second barrel, and at least one cam constituting an input of such differential. Therefore, it is necessary to find and size a suitable planetary gear (differential). Planetary gears have the advantage of achieving high transmission ratios in a small footprint. The input and output shafts are an extension of one another. There are many possibilities for combining gears. They make it possible, in particular, to produce interesting gearboxes. In the present case, it is a question of controlling one of the inputs of the differential, so as to generate an advance and respectively a delay of a specific equivalent value on each of the ends of the needle. And, when this value is zero, it is necessary to obtain a transmission ratio of 1 (the positive value means that the direction must also be the same).

La figure 8 montre un exemple d'une telle réalisation, avec une came en cœur en partie droite de la figure, parcourue par un levier courbe en forme de faucille comportant une partie dentée intérieurement, avec laquelle coopère une roue d'un premier différentiel, en partie gauche de la figure, un deuxième différentiel étant visible en partie droite arrière de la figure, ces deux différentiels attaquant deux canons coaxiaux. Le levier de cette figure est dépourvu de ressort de rappel, car c'est l'aiguille élastique qui remplit avantageusement cette fonction. Le levier actionne la couronne, qui par le biais des satellites visibles sur le schéma de principe d'un des deux différentiels, permet de générer l'avance ou le retard nécessaire.The figure 8 shows an example of such an embodiment, with a heart-shaped cam in the right part of the figure, traversed by a curved lever in the shape of a sickle comprising an internally toothed part, with which cooperates a wheel of a first differential, in the left part of the figure, a second differential being visible in the rear right part of the figure, these two differentials attacking two coaxial guns. The lever in this figure does not have a return spring, because it is the elastic needle which advantageously fulfills this function. The lever actuates the crown, which by means of the satellites visible on the principle diagram of one of the two differentials, makes it possible to generate the necessary advance or delay.

Ce mécanisme de la figure 8 remplit bien la fonction de génération d'avance ou de retard sur les canons, mais reste volumineux et comporte beaucoup de composants.This mechanism of the figure 8 performs well the function of generating lead or lag on the barrels, but remains bulky and has a lot of components.

L'invention se propose de simplifier encore le mécanisme et de le rendre encore plus compact et économique à produire. En particulier, quand il s'agit d'implanter l'aiguille élastique sur un petit calibre, tel une montre dame, et de surcroît sur l'aiguille des minutes. La difficulté principale est liée au faible couple à disposition. Il convient donc de créer un mécanisme avec la consommation d'énergie la plus faible possible.The invention proposes to further simplify the mechanism and to make it even more compact and economical to produce. In particular, when it comes to implanting the elastic hand on a small caliber, such as a lady's watch, and in addition on the minute hand. The main difficulty is linked to the low torque available. It is therefore necessary to create a mechanism with the lowest possible energy consumption.

En détournant le fonctionnement normal d'un différentiel, l'invention se propose de piloter le satellite. En implantant un palpeur dans le satellite, et en commandant ce dernier par une came ronde, nous obtenons un rapport de vitesse égal à un entre la roue solaire et le châssis porteur des satellites : l'ensemble se comporte alors comme un mobile.By diverting the normal operation of a differential, the invention proposes to control the satellite. By implanting a feeler in the satellite, and by controlling the latter by a round cam, we obtain a speed ratio equal to one between the sun wheel and the supporting frame of the satellites: the assembly then behaves like a mobile.

Le remplacement de la came ronde de cet exemple par une came de forme adéquate permet de piloter désormais l'avance ou le retard que nous désirons obtenir sur le canon. Il est à noter que là encore, le mécanisme est dépourvu de ressort de rappel pour conserver le contact du palpeur sur la came, car c'est l'aiguille élastique qui permet de remplir cette fonction.The replacement of the round cam of this example by a cam of adequate shape makes it possible from now on to control the advance or the delay which we wish to obtain on the barrel. It should be noted that here again, the mechanism does not have a return spring to keep the contact of the feeler on the cam, because it is the elastic needle which makes it possible to fulfill this function.

Dans le cas d'un châssis unique portant les deux satellites du premier et du deuxième différentiel, l'un au-dessus du châssis pour le deuxième canon, et l'autre en-dessous du châssis pour le premier canon, nous obtenons un système capable de reproduire les mêmes avance et retard que le mécanisme de la demande EP18186552 ou de la présent figure 8, avec seulement quatre dentures.In the case of a single frame carrying the two satellites of the first and of the second differential, one above the frame for the second gun, and the other below the frame for the first gun, we obtain a system able to reproduce the same lead and lag as the demand mechanism EP18186552 or from the present figure 8 , with only four teeth.

Les cames représentées sur la figure 2 permettent, ainsi, d'obtenir la trajectoire de la pointe de l'aiguille de la figure 5.The cams shown on the figure 2 allow, thus, to obtain the trajectory of the point of the needle of the figure 5 .

L'invention concerne ainsi, plus particulièrement, un mécanisme d'affichage 10 d'horlogerie à géométrie variable, comportant au moins une aiguille élastique 1.The invention thus relates, more particularly, to a variable geometry watch display mechanism 10, comprising at least one elastic hand 1.

Une telle aiguille élastique, et des mécanismes d'affichage comportant de telles aiguilles élastiques, ont été décrits dans les documents EP2863274 , EP3159751 , et EP18186552 , qui divulguent de nombreuses variantes.Such an elastic needle, and display mechanisms comprising such elastic needles, have been described in the documents EP2863274 , EP3159751 , and EP18186552 , which disclose many variations.

Cette aiguille élastique laquelle comporte un premier canon 2 d'entraînement solidaire d'une première extrémité d'une lame flexible 3, et un deuxième canon 4 d'entraînement solidaire d'une autre extrémité de la lame flexible 3.This elastic needle which comprises a first drive barrel 2 integral with a first end of a flexible blade 3, and a second drive barrel 4 integral with another end of the flexible blade 3.

Cette lame flexible 3 peut être une lame continue, ou encore une lame comportant une succession de segments 5 joints deux à deux au niveau de sommets 6, tel que visible sur les figures 5 et 6.This flexible strip 3 can be a continuous strip, or even a strip comprising a succession of segments 5 joined two by two at the vertices 6, as can be seen on the figures 5 and 6 .

Cette lame flexible 3 comporte un index d'affichage qui, dans un état libre non contraint de l'aiguille élastique 1 dans lequel à la fois le premier canon 2 et le deuxième canon 4 ne sont soumis à aucune contrainte et sont distants l'un de l'autre, est distant du premier canon 2 et du deuxième canon 4, la position de service de la aiguille élastique 1 étant une position contrainte où le premier canon 2 et le deuxième canon 4 sont coaxiaux l'un à l'autre autour d'un axe de sortie D. Notamment dans une variante comportant des segments 5 raboutés, l'index d'affichage est avantageusement, mais non nécessairement, constitué par un sommet 6.This flexible blade 3 comprises a display index which, in an unstressed free state of the elastic needle 1 in which both the first barrel 2 and the second barrel 4 are not subjected to any constraint and are distant from each other. on the other, is distant from the first barrel 2 and from the second barrel 4, the service position of the elastic needle 1 being a constrained position where the first barrel 2 and the second barrel 4 are coaxial with each other around of an output axis D. In particular in a variant comprising segments 5 joined together, the display index is advantageously, but not necessarily, constituted by a vertex 6.

Le mécanisme d'affichage 10 comporte des premiers moyens d'entraînement 11 du premier canon 2 autour de l'axe de sortie D, et des deuxièmes moyens d'entraînement 13 du deuxième canon 4 autour de l'axe de sortie D.The display mechanism 10 comprises first drive means 11 of the first barrel 2 around the output axis D, and second drive means 13 of the second barrel 4 around the output axis D.

Des variantes où le premier canon 2 et le deuxième canon 4 ne sont pas coaxiaux ne sont pas décrites ici, elles restent réalisables pour certains affichages spéciaux, notamment des affichages qui ne sont pas de révolution, tels des affichages rétrogrades ou similaires.Variants where the first barrel 2 and the second barrel 4 are not coaxial are not described here, they remain feasible for certain special displays, in particular displays which are not of revolution, such as retrograde displays or the like.

Les premiers moyens d'entraînement 11 et les deuxièmes moyens d'entraînement 13 sont agencés pour déformer la lame flexible 3, en faisant varier la position angulaire du deuxième canon 4 par rapport à la position angulaire du premier canon 2 autour de l'axe de sortie D, et pour faire varier la position radiale de l'index d'affichage par rapport à l'axe de sortie D.The first drive means 11 and the second drive means 13 are arranged to deform the flexible blade 3, by varying the angular position of the second barrel 4 relative to the angular position of the first barrel 2 around the axis of output D, and to vary the radial position of the display index relative to the output axis D.

Selon l'invention, le mécanisme d'affichage 10 comporte un premier différentiel 912 sur le rouage d'entraînement du premier canon 2, et dont une entrée est constituée par une première came 92 ou 820, et un deuxième différentiel 914 sur le rouage d'entraînement du deuxième canon 4, et dont une entrée est constituée par une deuxième came 94 ou 810. Selon la configuration adoptée, la première came peut être une came fixe ou une came mobile, et la deuxième came peut être, de la même façon, une came fixe ou une came mobile. Les figures 10, 12, 14, 16, illustrent certaines configurations particulières.According to the invention, the display mechanism 10 comprises a first differential 912 on the drive train of the first barrel 2, and one input of which is formed by a first cam 92 or 820, and a second differential 914 on the drive train. drive of the second barrel 4, and one input of which is constituted by a second cam 94 or 810. Depending on the configuration adopted, the first cam can be a fixed cam or a movable cam, and the second cam can be, in the same way , a fixed cam or a movable cam. The figures 10, 12 , 14 , 16 , illustrate some particular configurations.

Avantageusement, le premier différentiel 912 et le deuxième différentiel 914 comportent un châssis commun porte-satellite ou deux châssis synchrones chacun porte-satellite, porteur ou respectivement porteurs des satellites 82, 84, lesquels comportent chacun un palpeur excentré 83, 85, qui est agencé pour suivre sa came respective 92, 820, 94, 810, selon la variante.Advantageously, the first differential 912 and the second differential 914 comprise a common planet carrier chassis or two synchronous planet carrier chassis, each carrying or respectively carriers of the planet wheels 82, 84, which each comprise an eccentric feeler 83, 85, which is arranged to follow its respective cam 92, 820, 94, 810, depending on the variant.

Plus particulièrement, les premiers moyens d'entraînement 11 ou les deuxièmes moyens d'entraînement 13 sont agencés pour entraîner une autre entrée d'un différentiel d'entrée, qui est une autre entrée que la came citée ci-dessus constituant une des entrées du différentiel concerné. Ce différentiel d'entrée est l'un des premier différentiel 912 et deuxième différentiel 914; par exemple sur la variante des figures 1 et 2, le différentiel d'entrée est le deuxième différentiel 914.More particularly, the first drive means 11 or the second drive means 13 are arranged to drive another input of an input differential, which is another input than the cam mentioned above constituting one of the inputs of the input differential. differential concerned. This input differential is one of the first differential 912 and second differential 914; for example on the variant of figures 1 and 2 , the input differential is the second 914 differential.

Cette autre entrée est constituée par un premier satellite du différentiel d'entrée. Le premier satellite est monté libre en rotation sur un châssis porte-satellite d'entrée 80 qui est lui-même monté libre en rotation autour de l'axe de sortie D. Et le pignon solaire du différentiel d'entrée est constitué, ou bien par une première denture 21 que porte le premier canon 2 quand le différentiel d'entrée est le premier différentiel 912, ou bien par une deuxième denture 41 que porte le deuxième canon 4 quand le différentiel d'entrée est le deuxième différentiel 914. Par « châssis porte-satellite » on entend un châssis apte à porter au moins un satellite, sur n'importe laquelle de ses faces.This other input is formed by a first satellite of the input differential. The first satellite is mounted to rotate freely on an input satellite carrier frame 80 which is itself mounted to rotate freely around the output axis D. And the sun gear of the input differential is formed, or else by a first toothing 21 carried by the first barrel 2 when the input differential is the first differential 912, or else by a second toothing 41 carried by the second barrel 4 when the input differential is the second differential 914. By " satellite carrier chassis ”means a chassis capable of supporting at least one satellite, on any of its faces.

Plus particulièrement, l'autre des premier différentiel 912 et deuxième différentiel 914 est un différentiel de sortie, dont une autre entrée est constituée par un deuxième satellite du différentiel de sortie. Ce deuxième satellite est monté libre en rotation sur le châssis porte-satellite d'entrée 80 comme sur la figure 2, ou bien sur un châssis porte-satellite de sortie qui est monté libre en rotation autour de l'axe de sortie D et synchrone avec le châssis porte-satellite d'entrée 80. Le pignon solaire du différentiel de sortie est constitué par une deuxième denture 41 que porte le deuxième canon 4 quand le différentiel d'entrée est le premier différentiel 912, ou par une première denture 21 que porte le premier canon 2 quand le différentiel d'entrée est le deuxième différentiel 914.More particularly, the other of the first differential 912 and second differential 914 is an output differential, another input of which is constituted by a second satellite of the output differential. This second satellite is mounted freely in rotation on the entry satellite carrier frame 80 as on the figure 2 , or else on an output planet carrier frame which is mounted to rotate freely around the output axis D and synchronous with the input planet carrier frame 80. The sun gear of the output differential is formed by a second toothing 41 which the second barrel 4 carries when the input differential is the first differential 912, or by a first toothing 21 which the first barrel 2 carries when the input differential is the second differential 914.

Plus particulièrement, le deuxième satellite est monté libre en rotation sur le châssis porte-satellite d'entrée 80, sur la face opposée à celle qui porte le premier satellite, tel que visible sur les figures 2 et 3, qui montrent le châssis porte-satellite d'entrée 80 comportant des lamages en faces supérieure et inférieure, et des pions de pivot supérieur 81 et inférieur 89.More particularly, the second satellite is mounted to rotate freely on the entry satellite carrier frame 80, on the face opposite to that which carries the first satellite, as visible on the figures. figures 2 and 3 , which show the entry satellite carrier frame 80 comprising countersinks on the upper and lower faces, and upper 81 and lower 89 pivot pins.

Plus particulièrement, le premier différentiel 912 comporte un premier satellite 82 comportant un premier doigt excentré 83, lequel est agencé pour parcourir une première piste interne 93 de la première came 92 ou 820, notamment une came fixe, et est rappelé contre la première piste interne 93 par l'élasticité de l'aiguille élastique 1. De la même façon, le deuxième différentiel 914 comporte un deuxième satellite 84 comportant un deuxième doigt excentré 85, qui est agencé pour parcourir une deuxième piste interne 95 de la deuxième came 94 ou 810, notamment une came fixe, et qui est rappelé contre la deuxième piste interne 95 par l'élasticité de l'aiguille élastique 1. Il est avantageux d'utiliser l'élasticité de l'aiguille élastique 1 elle-même pour économiser un composant de rappel qui serait nécessaire pour assurer le plaquage de chaque palpeur sur sa piste de came.More particularly, the first differential 912 comprises a first satellite 82 comprising a first eccentric finger 83, which is arranged to travel a first internal track 93 of the first cam 92 or 820, in particular a fixed cam, and is biased against the first internal track 93 by the elasticity of the elastic needle 1. Likewise, the second differential 914 comprises a second satellite 84 comprising a second eccentric finger 85, which is arranged to run through a second internal track 95 of the second cam 94 or 810, in particular a fixed cam, and which is biased against the second internal track 95 by the elasticity of the elastic needle 1. It is advantageous to use the elasticity of the elastic needle 1 itself to save a return component which would be necessary to ensure the plating of each probe on its cam track.

On comprend que l'agencement relatif des cames 92, 820, 94, 810, peut être effectué de différentes façons :

  • ou bien au moins l'une des cames est distincte du châssis commun porte-satellite ou des deux châssis synchrones porte-satellite ;
  • ou bien les deux cames sont distinctes entre elles et chacune distincte du châssis commun porte-satellite ou des deux châssis synchrones porte-satellite ;
  • ou bien encore au moins l'une des cames est portée par le châssis commun porte-satellite ou un des deux châssis synchrones porte-satellite.
It is understood that the relative arrangement of the cams 92, 820, 94, 810 can be carried out in different ways:
  • or else at least one of the cams is separate from the common planet carrier frame or from the two synchronous planet carrier frames;
  • or else the two cams are distinct from each other and each separate from the common planet carrier frame or from the two synchronous planet carrier frames;
  • or else at least one of the cams is carried by the common planet carrier frame or one of the two synchronous planet carrier frames.

Dans une réalisation particulière, pour former un bloc additionnel de montage facile, la première came, 92 ou 820, notamment une came fixe, est fixée de façon indexée à la deuxième came, 94 ou 810, notamment une came fixe, avec laquelle elle forme une boîte. Cette boîte renferme le premier canon 2, le deuxième canon 4, et, interposé libre en rotation entre la première came 92 ou 820, notamment une came fixe, et la deuxième came 94 ou 810, notamment une came fixe, ou bien un châssis porte-satellite d'entrée 80 unique porteur de la totalité des mobiles du premier différentiel 912 et du deuxième différentiel 914, ou bien un châssis porte-satellite d'entrée 80 porteur de la totalité des mobiles du premier différentiel 912 et un châssis porte-satellite de sortie monté libre en rotation autour de l'axe de sortie D et synchrone avec le châssis porte-satellite d'entrée 80 et porteur de la totalité des mobiles du deuxième différentiel 914.In a particular embodiment, to form an additional block of easy assembly, the first cam, 92 or 820, in particular a fixed cam, is indexedly fixed to the second cam, 94 or 810, in particular a fixed cam, with which it forms a box. This box contains the first barrel 2, the second barrel 4, and, interposed freely in rotation between the first cam 92 or 820, in particular a fixed cam, and the second cam 94 or 810, in particular a fixed cam, or else a door frame. single entry satellite 80 carrying all of the moving bodies of the first differential 912 and of the second differential 914, or else an entry satellite carrier frame 80 carrying all of the moving bodies of the first differential 912 and a satellite carrier frame output mounted to rotate freely around the output axis D and synchronous with the input planet carrier frame 80 and carrying all of the moving parts of the second differential 914.

Plus particulièrement encore, le premier satellite est saillant radialement, en référence à l'axe de sortie D et par rapport à la première came, 92 ou 820, notamment une came fixe, et à la deuxième came, 94 ou 810, notamment une came fixe,, et est agencé pour coopérer avec un anneau denté intérieurement, que comporte le mécanisme d'affichage 10, pour l'entraînement de cette au moins une aiguille élastique 1.More particularly still, the first satellite protrudes radially, with reference to the output axis D and relative to the first cam, 92 or 820, in particular a fixed cam, and to the second cam, 94 or 810, in particular a cam fixed ,, and is arranged to cooperate with an internally toothed ring, which the display mechanism 10 comprises, for driving this at least one elastic needle 1.

La mise en œuvre de l'invention permet d'obtenir une grande variété d'affichages différents, selon la cinématique imposée aux cames et au châssis porte-satellite, ou aux châssis porte-satellite quand il y en a plusieurs.The implementation of the invention makes it possible to obtain a wide variety of different displays, depending on the kinematics imposed on the cams and the planet carrier frame, or on the planet carrier frames when there are several.

En effet, il est possible d'imposer une mise à l'arrêt d'une partie de ces constituants, qui peut être un arrêt permanent avec une fixation à demeure sur une platine, un pont, ou similaire, ou bien qui peut être un arrêt commandé du mobile concerné qui peut être libéré par l'utilisateur ou bien par le mouvement pour être mis en rotation, pour une durée limitée ou non, pour l'obtention passagère d'un effet d'affichage particulier.Indeed, it is possible to impose a shutdown of part of these constituents, which may be a permanent shutdown with permanent attachment to a plate, a bridge, or the like, or else which may be a controlled stop of the mobile concerned which can be released by the user or else by the movement to be rotated, for a limited period or not, for the temporary obtaining of a particular display effect.

Ainsi, dans une variante illustrée par la figure 10, la première came 92 ou 820 et la deuxième came 94 ou 810 sont fixes par rapport à une platine ou un pont que comporte le mécanisme d'affichage, et le châssis commun porte-satellite 80 dans le cas de la figure, ou les deux châssis synchrones porte-satellite, dans une autre variante non illustrée, est ou sont entraînés par un mécanisme de commande du mécanisme d'affichage 10. La figure 11 montre la trajectoire ovoïde T d'un sommet 6 de l'aiguille 1, associée à ce mécanisme.Thus, in a variant illustrated by figure 10 , the first cam 92 or 820 and the second cam 94 or 810 are fixed relative to a plate or a bridge that comprises the display mechanism, and the common planet carrier frame 80 in the case of the figure, or both synchronous satellite carrier chassis, in another variant not shown, is or are driven by a control mechanism of the display mechanism 10. The figure 11 shows the ovoid trajectory T of a vertex 6 of needle 1, associated with this mechanism.

Dans une autre variante, la première came, 92 ou 820, et la deuxième came, 94 ou 810, sont pivotantes et synchrones.In another variant, the first cam, 92 or 820, and the second cam, 94 or 810, are pivoting and synchronous.

Ainsi, dans une variante illustrée par la figure 12, la première came, 92 ou 820, et la deuxième came, 94 ou 810, sont pivotantes et synchrones, et le châssis commun porte-satellite 80 illustré, ou les deux châssis synchrones, chacun porte-satellite, est ou sont fixes par rapport à une platine ou un pont que comporte le mécanisme d'affichage 10. La figure 13 montre la trajectoire linéaire d'un sommet 6 de l'aiguille 1, associée à ce mécanisme, puisque cette aiguille élastique 1 ici ne tourne pas autour de l'axe de sortie D, mais change de longueur en fonction de la forme des cames, entre un rayon minimal RMIN et un rayon maximal RMAX ; une application consiste par exemple en un affichage de réserve de marche linéaire.Thus, in a variant illustrated by figure 12 , the first cam, 92 or 820, and the second cam, 94 or 810, are pivoting and synchronous, and the common planet carrier 80 frame shown, or the two synchronous frames, each carrier, is or are fixed relative to a plate or a bridge that comprises the display mechanism 10. The figure 13 shows the linear trajectory of a vertex 6 of needle 1, associated with this mechanism, since this elastic needle 1 here does not turn around the output axis D, but changes length depending on the shape of the cams, between a minimum radius RMIN and a maximum radius RMAX; one application consists, for example, of a linear power reserve display.

Dans une autre variante encore illustrée par la figure 14, la première came, 92 ou 820, et la deuxième came, 94 ou 810, sont pivotantes, et peuvent être bloquées en position fixe, mais de façon non permanente, car elles peuvent effectuer un mouvement de rotation à la demande, notamment mais non limitativement de un tour ou d'un nombre entier de tours. Ici la première came, 92 ou 820, et la deuxième came, 94 ou 810, sont pivotantes et synchrones, et le châssis commun porte-satellite 80 illustré, ou les deux châssis synchrones, chacun porte-satellite, dans une autre variante non illustrée, est ou sont pivotants de façon coaxiale par rapport à la première came, 92 ou 820, et la deuxième came, 94 ou 810. Plus particulièrement, le mécanisme d'affichage 10 comporte alors un mécanisme de commande à la demande pour faire pivoter ensemble la première came, 92 ou 820, et la deuxième came, 94 ou 810, et pour faire varier l'extension radiale de l'aiguille élastique 1 par rapport à l'axe de sortie D.In another variant further illustrated by figure 14 , the first cam, 92 or 820, and the second cam, 94 or 810, are pivoting, and can be locked in a fixed position, but not permanently, because they can perform a rotational movement on demand, in particular but not limited to one turn or a whole number of turns. Here the first cam, 92 or 820, and the second cam, 94 or 810, are pivoting and synchronous, and the common planet carrier frame 80 shown, or the two synchronous frames, each planet carrier, in a another variant not shown, is or are pivoting coaxially with respect to the first cam, 92 or 820, and the second cam, 94 or 810. More particularly, the display mechanism 10 then comprises a demand control mechanism to rotate together the first cam, 92 or 820, and the second cam, 94 or 810, and to vary the radial extension of the elastic needle 1 with respect to the output axis D.

La figure 15 montre la trajectoire carrée T d'un sommet 6 de l'aiguille 1, associée au mécanisme de la figure 14. Ce sommet 6 est distant de l'axe de sortie D d'une distance qui varie entre un rayon minimal RMIN et un rayon maximal RMAX. Lors du fonctionnement, lorsque les cames, 92 ou 820, et 94 ou 810, sont à l'arrêt, ce somment 7 suit la trajectoire carrée aux coins arrondis T. Lorsque l'on commande la rotation des cames, l'aiguille 1 pointe toujours la même direction, mais change de longueur, à la façon d'une pulsation cardiaque : l'aiguille 1 a ici la forme d'un cœur qui palpite à la demande.The figure 15 shows the square trajectory T of a vertex 6 of the needle 1, associated with the mechanism of the figure 14 . This vertex 6 is distant from the output axis D by a distance which varies between a minimum radius RMIN and a maximum radius RMAX. During operation, when the cams, 92 or 820, and 94 or 810, are at a standstill, this point 7 follows the square path with rounded corners T. When controlling the rotation of the cams, needle 1 points always the same direction, but changes length, like a heartbeat: needle 1 here has the shape of a heart which beats on demand.

La figure 16 illustre, de façon similaire aux figures 10, 12, et 14, une autre variante où l'une des cames, ici la deuxième came 810, est portée par le châssis porte-satellite 80 : elle coopère avec le deuxième doigt excentré 85 du deuxième satellite 84 qui est porté par le pion de pivot 81 du même châssis porte-satellite 80 ; sur la face inférieure de ce châssis porte-satellite 80 est guidé, de façon similaire, le premier satellite 82, dont le premier doigt excentré 83 coopère avec la première piste interne 93 de la première came 92. Bien sûr la configuration symétrique peut être réalisée avec une première came 820 ménagée au niveau du châssis porte-satellite 80, et d'une deuxième came 94 extérieure à ce dernier.The figure 16 illustrates, similarly to figures 10, 12 , and 14 , another variant where one of the cams, here the second cam 810, is carried by the planet carrier frame 80: it cooperates with the second eccentric finger 85 of the second satellite 84 which is carried by the pivot pin 81 of the same satellite carrier frame 80; on the lower face of this planet carrier frame 80 is guided, in a similar manner, the first planet gear 82, the first eccentric finger 83 of which cooperates with the first internal track 93 of the first cam 92. Of course, the symmetrical configuration can be achieved. with a first cam 820 formed at the level of the planet carrier frame 80, and a second cam 94 outside the latter.

L'invention concerne encore un mouvement d'horlogerie 900 comportant au moins un tel mécanisme d'affichage 10.The invention also relates to a timepiece movement 900 comprising at least one such display mechanism 10.

L'invention concerne encore une montre 1000 comportant au moins un tel mouvement 900, et/ou au moins un tel mécanisme d'affichage 10.The invention also relates to a watch 1000 comprising at least one such movement 900, and / or at least one such display mechanism 10.

En somme, l'invention permet de générer de l'avance et/ou du retard sur les deux canons de l'aiguille élastique, permettant de générer des trajectoires complexes, le tout d'une manière très simple, compacte, peu gourmande en couple et donc d'une grande fiabilité.In short, the invention makes it possible to generate the advance and / or the delay on the two barrels of the elastic needle, making it possible to generate complex trajectories, all in a very simple, compact way that does not consume much torque. and therefore of great reliability.
