Description

Domaine de l'inventionField of the invention

L'invention concerne un mécanisme d'affichage d'horlogerie à saut instantané, agencé pour être entraîné par un mouvement d'horlogerie, et comportant un mécanisme d'arrêtage de type à croix de Malte avec un mobile directeur apte à commander dans une partie de sa course angulaire le pivotement d'au moins un mobile satellite.The invention relates to an instantaneous jump timepiece display mechanism, arranged to be driven by a timepiece movement, and comprising a Maltese cross-type stop mechanism with a directing mobile able to control in a part of its angular stroke the pivoting of at least one mobile satellite.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant au moins un tel mécanisme d'affichage.The invention also relates to a timepiece, in particular a watch, comprising at least one such display mechanism.

L'invention concerne le domaine des mécanismes d'affichage pour pièces d'horlogerie à complications.The invention relates to the field of display mechanisms for timepieces with complications.

Arrière-plan de l'inventionBackground of the invention

On connaît l'utilisation de mécanismes d'arrêtage à croix de Malte pour réaliser certaines fonctions d'affichage en horlogerie. La plus connue est l'affichage de l'année bissextile sur une pièce d'horlogerie à quantième perpétuel.The use of Maltese cross stop mechanisms to perform certain display functions in horology is known. The best known is the display of the leap year on a timepiece with a perpetual calendar.

Habituellement, un mécanisme à croix de Malte est dit traînant. Le satellite est en rotation continue autour de la planète, et la rotation du satellite sur son axe propre est elle aussi traînante.Usually, a Maltese cross mechanism is said to be trailing. The satellite is in continuous rotation around the planet, and the rotation of the satellite on its own axis is also dragging.

Les affichages traînants amènent une incertitude pour l'utilisateur, surtout au voisinage de l'instant de changement d'affichage, car il ne dispose pas de moyens pour savoir si le changement d'affichage a été effectué ou non.Trailing displays cause uncertainty for the user, especially in the vicinity of the display change instant, because he does not have the means to know whether the display change has been performed or not.

Le document WO2010/058367A1 au nom de BALLOUARD décrit un mécanisme d'affichage d'une montre dont le mouvement permet d'entraîner une chaussée, à l'extrémité libre de laquelle est fixé un organe indicateur effectuant un tour par heure au-dessus d'un cadran doté de douze ou de vingt-quatre repères indiquant les heures dans une disposition circulaire. Ces repères sont chacun associés à un pignon isolé, doté d'un nombre pair de dents, entraîné simultanément avec un de ses pignons adjacents par engrènement avec un secteur denté dont le diamètre primitif est égal à la moitié du nombre de repères multiplié par le diamètre primitif du pignon, et qui est actionné en rotation, autour de cette chaussée et après chaque tour de l'organe indicateur, d'une valeur angulaire égale à un tour divisé par le nombre de repère, par le biais d'un moyen de commande lui-même entraîné par la rotation de cette chaussée.The document WO2010/058367A1 in the name of BALLOUARD describes a mechanism for displaying a watch whose movement makes it possible to drive a roadway, at the free end of which is fixed an indicator member carrying out one revolution per hour above a dial equipped with twelve or twenty-four markers indicating the hours in a circular arrangement. These markers are each associated with an isolated pinion, equipped with an even number of teeth, driven simultaneously with one of its adjacent pinions by meshing with a toothed sector whose pitch diameter is equal to half the number of markers multiplied by the diameter pitch of the pinion, and which is actuated in rotation, around this roadway and after each revolution of the indicator member, by an angular value equal to one revolution divided by the number of marks, by means of a control means itself driven by the rotation of this roadway.

Le document CH3366A au nom de JACCARD décrit une montre dite "montre sans aiguilles", comportant une combinaison d'un canon portant une came et une roue, avec un disque-doigt destiné à actionner une roue croix-de-Malte. Ce disque portant l'une des extrémités d'un ressort spiral dont l'autre extrémité est fixée au canon ou à l'arbre portant ce dernier, et une dent ou projection inférieure traversant une ouverture de la roue, en combinaison avec un levier ou bras ayant une dent ou projection et avec un ressort ; la dent ou projection arrêtant temporairement le disque-doigt pendant la rotation continue du canon, pour l'abandonner à lui-même dès que la dent ou projection tombe dans l'encoche des cames.The document CH3366A in the name of JACCARD describes a watch called a "watch without hands", comprising a combination of a barrel carrying a cam and a wheel, with a finger disc intended to actuate a Maltese cross wheel. This disc carrying one of the ends of a spiral spring, the other end of which is fixed to the barrel or to the shaft carrying the latter, and a lower tooth or projection passing through an opening of the wheel, in combination with a lever or arm having a tooth or projection and with a spring; the tooth or projection temporarily stopping the disc-finger during the continuous rotation of the barrel, to abandon it to itself as soon as the tooth or projection falls into the notch of the cams.

La figure 1 expose la problématique générale du mouvement orbital d'un mobile satellite autour d'un élément fixe ou mobile dénommé planète, où le mobile satellite est en mouvement continu de rotation (flèches A) autour de la planète, et, dans au moins une position angulaire ici représentée non limitativement à six heures, effectue un pivotement sur lui-même (flèche B), la course angulaire de ce pivotement dépendant de l'agencement du mécanisme.There figure 1 exposes the general problem of the orbital movement of a mobile satellite around a fixed or mobile element called planet, where the mobile satellite is in continuous rotational movement (arrows A) around the planet, and, in at least one angular position shown here without limitation at six o'clock, pivots on itself (arrow B), the angular stroke of this pivoting depending on the arrangement of the mechanism.

L'invention est illustrée dans une variante particulière avec un seul point de rotation des satellites, on comprend qu'un mécanisme d'affichage particulier peut comporter plusieurs tels points de rotation répartis sur la périphérie de la planète, selon l'application d'affichage désirée.The invention is illustrated in a particular variant with a single point of rotation of the satellites, it is understood that a particular display mechanism may comprise several such points of rotation distributed over the periphery of the planet, depending on the display application desired.

L'invention concerne un mécanisme d'affichage 100 d'horlogerie à saut instantané. Ce mécanisme d'affichage 100 est agencé pour être entraîné par un mouvement d'horlogerie, et comporte un mécanisme d'arrêtage de type dit « à croix de Malte » avec un mobile directeur 200 apte à commander, dans au moins une partie de sa course angulaire, le pivotement d'au moins un mobile satellite 300.The invention relates to an instantaneous jump timepiece display mechanism 100 . This display mechanism 100 is arranged to be driven by a clock movement, and comprises a stop mechanism of the so-called "Maltese cross" type with a director mobile 200 capable of controlling, in at least part of its angular stroke, the pivoting of at least one mobile satellite 300.

Selon l'invention, ce mobile directeur 200 comporte une couronne 10, qui est agencée pour être entraînée indirectement en pivotement depuis un mobile entraîneur ou une chaussée 12 que comporte un mouvement d'horlogerie, au travers d'un mobile de came 456.According to the invention, this director wheel set 200 comprises a ring gear 10, which is arranged to be driven indirectly in pivoting from a drive wheel set or a roadway 12 that includes a clockwork movement, through a cam wheel set 456.

Ce mobile de came 456 est agencé pour faire passer la couronne 10 d'une position armée à une position désarmée par un déplacement instantané de la couronne 10 dans un premier sens pour faire pivoter un mobile satellite 300 autour d'un axe de satellite, et pour faire passer la couronne 10 de la position désarmée à la position armée par un déplacement régulé de la couronne 10 plus lent que le déplacement instantané lors d'un mouvement de retour dans un deuxième sens opposé au premier sens.This cam wheel set 456 is arranged to move the ring gear 10 from an armed position to a disarmed position by an instantaneous movement of the ring gear 10 in a first direction to make a satellite wheel set 300 pivot around a satellite axis, and to move the crown 10 from the disarmed position to the armed position by a regulated displacement of the crown 10 slower than the instantaneous displacement during a return movement in a second direction opposite to the first direction.

Le mobile de came 456 comporte, montés coaxiaux, au moins un plateau 15 et une came 16. Le plateau 15 est entraîné indirectement par la chaussée 12, et comporte une ganse 151, agencée pour la limitation de course et pour l'entraînement en position de butée à une extrémité de la ganse, d'un doigt excentré 160 que comporte la came 16. Le profil évolutif 161 de la came 16 commande le pivotement d'un entraîneur 17, lequel est agencé pour entraîner la couronne 10 entre deux positions extrêmes d'armement et de désarmement. La ganse 151 permet ainsi, d'une part un saut franc de l'entraîneur 17 qui interagit avec la came 16 dans le sens du désarmement, et d'autre part une durée plus longue de réarmement liée au parcours relatif du doigt 160 et de la ganse 151. L'utilité du système ganse-doigt est d'avoir une chute instantanée du palpeur, qui lui quand il chute touche le plus petit rayon de la came.The cam wheel set 456 comprises, mounted coaxially, at least one plate 15 and one cam 16. The plate 15 is driven indirectly by the roadway 12, and comprises a loop 151, arranged for the stroke limitation and for driving in position stop at one end of the loop, an eccentric finger 160 that comprises the cam 16. The changing profile 161 of the cam 16 controls the pivoting of a driver 17, which is arranged to drive the crown 10 between two extreme positions of armament and disarmament. The loop 151 thus allows, on the one hand a free jump of the trainer 17 which interacts with the cam 16 in the direction of the disarmament, and on the other hand a longer duration of rearmament related to the relative course of the finger 160 and of the loop 151. The usefulness of the loop-finger system is to have an instantaneous fall of the feeler, which when it falls touches the smallest radius of the cam.

Plus particulièrement, le mobile directeur 200 comporte une première alternance de premières zones de glissement et de premières zones d'entraînement, et le mobile satellite 300 comporte une deuxième alternance de deuxièmes zones de dégagement et de deuxièmes zones d'entraînement. Les deuxièmes zones de dégagement sont agencées pour glisser chacune à leur tour sur une des premières zones de glissement du mobile directeur pendant une partie de la course angulaire du mobile directeur 200 correspondant à une position de repos du mobile satellite 300. Et les premières zones d'entraînement du mobile directeur 200 sont agencées pour, dans certaines portions de la course angulaire du mobile directeur 200, coopérer avec les deuxièmes zones d'entraînement que comporte le mobile satellite 300 pour entraîner en pivotement le mobile satellite 300 jusqu'à la remise en coopération d'une deuxième zone de dégagement avec une première zone de glissement dans une nouvelle position de repos du mobile satellite 300.More particularly, the director mobile 200 comprises a first alternation of first sliding zones and first driving zones, and the satellite mobile 300 comprises a second alternation of second clearance zones and second driving zones. The second clearance zones are arranged to slide each in turn on one of the first sliding zones of the director mobile during part of the angular travel of the director mobile 200 corresponding to a rest position of the satellite mobile 300. And the first zones of drive of the director mobile 200 are arranged to, in certain portions of the angular travel of the director mobile 200, cooperate with the second drive zones that the satellite mobile 300 comprises to pivotally drive the satellite mobile 300 until the cooperation of a second clearance zone with a first sliding zone in a new rest position of the mobile satellite 300.

Plus particulièrement, l'entraîneur 17 est un râteau pivotant, qui est rappelé par un ressort de râteau 18, et qui comporte une denture de râteau 170 qui est agencée pour coopérer avec une denture interne de couronne 107 que comporte la couronne 10. Ce râteau pivotant comporte un palpeur 171, qui est agencé pour suivre le profil de la came 16.More particularly, the driver 17 is a pivoting rake, which is returned by a rake spring 18, and which comprises a rake toothing 170 which is arranged to cooperate with an internal crown toothing 107 that the crown 10 comprises. swivel includes a sensor 171, which is arranged to follow the profile of the cam 16.

Plus particulièrement, la came 16 est une came-limaçon avec un profil externe évolutif 161 en escargot et un front 162 permettant le saut. Et la combinaison de la ganse 151 et du doigt 160 permet et limite le retour du palpeur 171 sur le plus grand rayon de la came 16.More particularly, the cam 16 is a snail cam with an evolving external profile 161 snail and a front 162 allowing the jump. And the combination of the loop 151 and the finger 160 allows and limits the return of the sensor 171 on the largest radius of the cam 16.

Dans une exécution particulière, ce profil externe évolutif 161 en escargot est en croissance sur les premiers 180° de la came, et est suivi par une partie concentrique à évolution nulle sur le reste de la course angulaire ; ainsi la couronne dentée, en position armée, peut attendre l'arrivée du satellite. De préférence la rampe de montée n'est pas trop rapide, de façon à éviter toute interférence avec le satellite qui vient de sauter.In a particular embodiment, this snail-shaped external profile 161 grows over the first 180° of the cam, and is followed by a concentric part with zero evolution over the rest of the angular stroke; thus the ring gear, in the armed position, can wait for the arrival of the satellite. Preferably the ascent ramp is not too fast, so as to avoid any interference with the satellite which has just jumped.

De façon avantageuse, le front 162 comporte une pente qui permet la réversibilité du mécanisme, qui est utile lors d'un réglage comme une mise à l'heure, qui peut nécessiter un mouvement en arrière.Advantageously, the front 162 has a slope which allows the reversibility of the mechanism, which is useful during an adjustment such as setting the time, which may require a backward movement.

Selon l'invention, le mobile de came 456 comporte encore, montée coaxiale avec le plateau 15 et la came 16, une roue à friction 14 qui est entraînée directement ou indirectement (par exemple au travers d'un mobile de minuterie 13) par la chaussée 12, et qui est agencée pour entraîner par friction un tourillon 152 du plateau 15, et dont l'ajustement angulaire par rapport au plateau permet un réglage précis de l'instant du saut de la couronne 10.According to the invention, the cam wheel set 456 further comprises, mounted coaxially with the plate 15 and the cam 16, a friction wheel 14 which is driven directly or indirectly (for example through a timer wheel set 13) by the floor 12, and which is arranged to drive by friction a pin 152 of the plate 15, and whose angular adjustment relative to the plate allows precise adjustment of the moment of the jump of the crown 10.

Plus particulièrement, la couronne 10 est annulaire et pivote, guidée par des galets de couronne 19 excentrés par rapport à son axe de pivotement. Ce guidage par galet n'est naturellement pas exclusif, il s'agit d'un cas particulier et non limitatif de système de guidage.More particularly, crown 10 is annular and pivots, guided by crown rollers 19 eccentric with respect to its pivot axis. This roller guidance is naturally not exclusive, it is a particular and non-limiting case of a guidance system.

Plus particulièrement, le mécanisme d'affichage 100 comporte une étoile 4 porteuse de chaque mobile satellite 300, qui est montée pivotante, dans un pivotement continu dans un unique sens de pivotement, et entraînée par un mobile du mouvement d'horlogerie. Ce mouvement continu de l'étoile est un cas particulier, non limitatif : on comprend que, par exemple lors d'un réglage de mise à l'heure ou similaire, la rotation peut ne pas être continue ; il en est de même pour le sens de rotation, qui peut aussi être inversé, notamment dans le même exemple d'un réglage de mise à l'heure.More particularly, the display mechanism 100 comprises a carrier star 4 of each satellite mobile 300, which is pivotally mounted, in a continuous pivoting in a single direction of pivoting, and driven by a mobile of the clockwork. This continuous movement of the star is a particular, non-limiting case: it is understood that, for example during a setting of the time or the like, the rotation may not be continuous; the same is true for the direction of rotation, which can also be reversed, in particular in the same example of a time-setting.

De préférence, les axes de pivotement de la couronne 10 et de l'étoile 4 sont confondus ; plus particulièrement, ils sont coaxiaux avec l'axe de pivotement principal D de la roue des heures 1 ou la chaussée 12 du mouvement d'horlogerie.Preferably, the pivot axes of crown 10 and star 4 coincide; more particularly, they are coaxial with the main pivot axis D of the hour wheel 1 or the roadway 12 of the clock movement.

Dans une variante, chaque mobile satellite 300 est monté pivotant fou sur un bras 7 ou la périphérie de l'étoile 4.In a variant, each mobile satellite 300 is mounted to pivot freely on an arm 7 or the periphery of the star 4.

Dans une autre variante, chaque mobile satellite 300 est monté pivotant avec friction dans un logement que comporte un bras 7 ou la périphérie de l'étoile 4.In another variant, each mobile satellite 300 is pivotally mounted with friction in a housing that includes an arm 7 or the periphery of the star 4.

De façon particulière, chaque mobile satellite 300, notamment une roue satellite 8, est monté à l'extrémité 71 d'un bras 7, que comporte l'étoile 4, et qui, dans une variante particulière, est flexible. Cette extrémité 71 de bras 7 peut encore comporter un palier pour le guidage d'un autre mobile engrenant avec la roue satellite 8. La roue satellite 8 peut comporter un moyeu de satellite 80, guidé dans un alésage de l'extrémité 71 de bras 7, ou dans une pince à friction que comporte cette extrémité 71 de bras 7, formée par un bras flexible complémentaire 72. La roue satellite 8 peut encore comporter au moins un flasque 83 de limitation axiale par rapport à l'extrémité 71 de bras 7.In particular, each satellite mobile 300, in particular a satellite wheel 8, is mounted at the end 71 of an arm 7, which includes the spider 4, and which, in a particular variant, is flexible. This end 71 of arm 7 may also include a bearing for guiding another mobile unit meshing with the planet gear 8. The planet gear 8 may include a planet gear hub 80, guided in a bore in the end 71 of arm 7 , or in a friction clamp that this end 71 of arm 7 comprises, formed by a complementary flexible arm 72. The planet wheel 8 can also comprise at least one flange 83 for axial limitation with respect to the end 71 of arm 7.

Dans la variante particulière illustrée par les figures, chaque mobile satellite 300 comporte une denture tronquée comportant des dents 81, 811, 812, 813, 814, 815, 816, qui sont agencées pour coopérer avec une partie dentée externe 108 que comporte la couronne 10, notamment des dents de couronne 1802, 1804, que comporte la couronne 10 pour leur entraînement relatif. La couronne 10 comporte des dégagements 1801, 1803, 1805 entre sa structure et les dents 1802 et 1804. Et chaque mobile satellite 300 comporte des zones dégagées 82, 821, 822, qui constituent des deuxièmes zones de dégagement, permettant le glissement du mobile satellite 300 sur une portée cylindrique 9 lisse que comporte la couronne 10. Dans l'exemple illustré par les figures, le glissement se fait au niveau des dents 811, 816, d'une part, et 813 et 814 d'autre part, du mobile satellite 300, qui sont collatérales à chaque deuxième zone de dégagement.In the particular variant illustrated by the figures, each mobile satellite 300 comprises a truncated toothing comprising teeth 81, 811, 812, 813, 814, 815, 816, which are arranged to cooperate with an external toothed part 108 that comprises the crown 10 , in particular crown teeth 1802, 1804, which the crown 10 comprises for their relative drive. The crown 10 has clearances 1801, 1803, 1805 between its structure and the teeth 1802 and 1804. And each satellite mobile 300 has cleared areas 82, 821, 822, which constitute second clearance areas, allowing the sliding of the satellite mobile 300 on a cylindrical bearing surface 9 smooth that includes the crown 10. In the example illustrated by the figures, the sliding takes place at the level of the teeth 811, 816, on the one hand, and 813 and 814 on the other hand, of the mobile satellite 300, which are collateral to each second clearing zone.

Dans l'exemple illustré par les figures, les mobiles satellites 300 comportent chacun deux deuxièmes zones de dégagement 821, 822, qui permettent une rotation à 180° du satellite. On comprend que d'autres exécutions sont possibles, par exemple trois deuxièmes zones dégagées pour une rotation de 120°, ou autre ; de la même façon, ces deuxièmes zones dégagées ne sont pas nécessairement équidistantes.In the example illustrated by the figures, the mobile satellites 300 each comprise two second clearance zones 821, 822, which allow a 180° rotation of the satellite. It is understood that other executions are possible, for example three second free zones for a rotation of 120°, or other; in the same way, these second cleared zones are not necessarily equidistant.

Dans une autre variante non illustrée, chaque mobile satellite 300 est une croix de Malte avec des branches comportant chacune un profil creux cylindrique constituant une deuxième zone de dégagement, qui est agencée pour glisser sur une portée cylindrique 9 que comporte la couronne 10. Les branches de cette croix de Malte sont classiquement séparées par des évidements, qui sont agencés pour coopérer avec un doigt, ou une dent, ou similaire, saillant de la couronne 10 pour leur entraînement relatif en pivotement.In another variant not shown, each satellite mobile 300 is a Maltese cross with branches each comprising a hollow cylindrical profile constituting a second clearance zone, which is arranged to slide on a cylindrical bearing surface 9 that comprises crown 10. The branches of this Maltese cross are conventionally separated by recesses, which are arranged to cooperate with a finger, or a tooth, or the like, projecting from the crown 10 for their relative drive in pivoting.

Dans une autre variante encore, non illustrée, le mécanisme comporte une croix de Malte qui fonctionne sur une denture intérieure.In yet another variant, not illustrated, the mechanism comprises a Maltese cross which operates on an internal toothing.

Dans une variante particulière de réalisation, le mécanisme d'affichage 100 est un affichage de phase de lune ou d'âge de lune.In a particular embodiment variant, the display mechanism 100 is a moon phase or moon age display.

Dans une autre variante particulière de réalisation, le mécanisme d'affichage 100 est un affichage jour/nuit.In another particular embodiment variant, the display mechanism 100 is a day/night display.

Dans une autre variante particulière de réalisation, le mécanisme d'affichage 100 est un affichage AM/PM.In another particular variant embodiment, the display mechanism 100 is an AM/PM display.

Dans une autre variante particulière de réalisation, le mécanisme d'affichage 100 est un affichage d'heure universelle.In another particular embodiment variant, the display mechanism 100 is a universal time display.

Dans une autre variante particulière de réalisation, le mécanisme d'affichage 100 est un affichage de calendrier, de quantième, de jour, ou de mois, ou d'année bissextile.In another particular embodiment variant, the display mechanism 100 is a calendar, date, day, or month, or leap year display.

L'invention concerne encore une pièce d'horlogerie 1000 comportant un mouvement d'horlogerie, qui est agencé pour entraîner au moins un tel mécanisme d'affichage 100. Selon l'invention, ce mécanisme d'affichage 100 comporte un entraînement distinct du mobile directeur 200 selon un pivotement de va-et-vient avec une course angulaire limitée, et du pivotement continu dans un sens unique d'une étoile 4 porteuse de chaque mobile satellite 300.The invention also relates to a timepiece 1000 comprising a timepiece movement, which is arranged to drive at least one such display mechanism 100. According to the invention, this display mechanism 100 comprises a drive separate from the mobile director 200 according to a back-and-forth pivoting with a limited angular travel, and the continuous pivoting in one direction of a carrier star 4 of each mobile satellite 300.

Plus particulièrement, cette pièce d'horlogerie 1000 est une montre.More particularly, this timepiece 1000 is a watch.

Les figures illustrent une variante particulière, non limitative, de l'invention, et permettent de détailler son fonctionnement.The figures illustrate a particular, non-limiting variant of the invention, and provide details of its operation.

Le mécanisme d'affichage 100 est ici composé de deux sous-systèmes, qui sont combinés l'un à l'autre :

  • un premier mécanisme concerne l'entraînement de l'étoile 4, qui porte la roue satellite 300, ou les roues satellites 3000 dans le cas d'espèce : ce mécanisme est agencé pour effectuer une prise d'information sur rouage d'un mouvement d'horlogerie mécanique, ou électro-mécanique, pour réaliser une réduction de la vitesse de rotation par train d'engrenage, la transmission et le guidage en rotation ;
  • un deuxième mécanisme concerne l'entraînement de la couronne 10, qui porte la dent fixe type croix de Malte ; ce mécanisme est agencé pour effectuer une prise d'information sur rouage d'un mouvement mécanique, ou électro-mécanique, autoriser un réglage par l'utilisation d'un système à friction, déclencher un saut par l'utilisation d'un mécanisme à came, la transmission et le guidage en rotation.
The display mechanism 100 is here composed of two subsystems, which are combined with each other:
  • a first mechanism concerns the drive of the star wheel 4, which carries the satellite wheel 300, or the satellite wheels 3000 in the present case: this mechanism is arranged to carry out an information pick-up on the cog of a movement of mechanical or electro-mechanical clockwork, to achieve a reduction in the speed of rotation by gear train, transmission and rotational guidance;
  • a second mechanism concerns the driving of the crown 10, which carries the fixed tooth of the Maltese cross type; this mechanism is arranged to take information from the cog of a mechanical or electro-mechanical movement, to authorize adjustment by the use of a friction system, to trigger a jump by the use of a mechanism with cam, transmission and rotation guidance.

Le sous-système relatif à l'entraînement de l'étoile 4, illustré par la figure 2, a pour but de mettre en rotation à vitesse constante les mobiles satellites 300, ici des roues satellites 8, autour d'une platine 5.The star 4 drive subsystem, illustrated by the figure 2 , aims to rotate the satellite wheels 300 at a constant speed, here satellite wheels 8, around a plate 5.

Pour réaliser ce mouvement, l'information est prise au centre d'un mouvement d'horlogerie, notamment mais non limitativement sur une roue des heures 1 comportant une denture 11, cette information est transmise par un train d'engrenage, comportant notamment un mobile réducteur 2 comportant des dentures 21 et 22, et un renvoi entraîneur 3, jusqu'à l'étoile 4, via sa denture intérieure 43. L'étoile 4 pivote autour de la platine 5 grâce à des galets d'étoile 6 guidant un alésage 46 de l'étoile 4, et effectue une révolution en douze heures dans le sens horaire dans le cas particulier illustré. Naturellement, cette révolution en douze heures est une construction particulière illustrée par les figures, et d'autres valeurs de période peuvent être choisies pour d'autres applications, sans s'éloigner de l'invention. Plus particulièrement, l'étoile 4 comporte une denture intérieure 43 au niveau d'une serge annulaire qui pivote, guidée par des galets d'étoile 6 excentrés par rapport à l'axe de pivotement de l'étoile 4. Le guidage par galets n'est qu'un cas particulier illustré par les figures, on peut imaginer d'autres modes de guidage, comme un guidage rotatif par roulement, ou autre. Cette denture 43 coopère avec la denture 32 du renvoi entraîneur 3.To produce this movement, the information is taken from the center of a watch movement, in particular but not limited to an hour wheel 1 comprising a toothing 11, this information is transmitted by a gear train, in particular comprising a mobile reducer 2 comprising teeth 21 and 22, and a driving gear 3, up to star 4, via its internal toothing 43. Star 4 pivots around plate 5 thanks to star rollers 6 guiding a bore 46 of star 4, and completes one revolution in twelve hours clockwise in the particular case illustrated. Naturally, this revolution in twelve hours is a particular construction illustrated by the figures, and other period values can be chosen for other applications, without departing from the invention. More particularly, the star 4 comprises an internal toothing 43 at the level of an annular rim which pivots, guided by star rollers 6 eccentric with respect to the pivot axis of the star 4. Guide by rollers n It is only a particular case illustrated by the figures, one can imagine other modes of guidance, such as a rotary guidance by rolling, or other. This toothing 43 cooperates with the toothing 32 of the driving gear 3.

L'étoile 4 comporte ici douze bras 7, ce sont plus particulièrement mais non limitativement des bras flexibles, ces bras 7 permettent de réaliser un pivot avec chaque roue satellite 8. Les roues satellites 8 sont entraînées en rotation autour de la platine 5 par l'étoile 4, et elles sont guidées angulairement la plupart du temps par la couronne 10, par glissement de la denture des roues satellites 8 contre la surface cylindrique 9 externe de la couronne 10.The star 4 here comprises twelve arms 7, these are more particularly but not limited to flexible arms, these arms 7 make it possible to produce a pivot with each planet wheel 8. The planet wheels 8 are driven in rotation around the plate 5 by the star 4, and they are angularly guided most of the time by the crown 10, by sliding of the teeth of the planet gears 8 against the outer cylindrical surface 9 of the crown 10.

Chaque roue satellite 8 effectue une rotation complète autour de la platine 5 en douze heures, et sans pour autant tourner sur elle-même.Each satellite wheel 8 performs a complete rotation around the plate 5 in twelve hours, and without turning on itself.

Le sous-système relatif à l'entraînement de la couronne 10 a pour but de gérer le déplacement et la position angulaire de la couronne 10.The purpose of the subsystem relating to the drive of crown 10 is to manage the movement and the angular position of crown 10.

La couronne 10 passe de la position armée à désarmée par un déplacement instantané rapide, puis revient en position armée par un déplacement régulé lent. Plus particulièrement, la montée lors du retour en position armée est évolutive au début, et nulle à la fin.The crown 10 passes from the armed position to disarmed by a rapid instantaneous displacement, then returns to the armed position by a slow regulated displacement. More specifically, the climb when returning to the armed position is progressive at the beginning, and zero at the end.

Pour réaliser ces différents mouvements de la couronne 10, l'information est, notamment et non limitativement prise au centre du mouvement d'horlogerie sur une chaussée 12, et est transmise par un mobile de minuterie 13 jusqu'à un mobile de came 456. Ce mobile de came 456 comporte une roue à friction 14, qui dispose ainsi d'une vitesse de rotation constante, et effectue une révolution en une heure dans le sens horaire (sur les figures SAM = sens des aiguilles d'une montre).To carry out these different movements of the crown 10, the information is, in particular and not limited to, taken from the center of the clock movement on a roadway 12, and is transmitted by a timer wheel set 13 to a cam wheel set 456. This cam wheel 456 comprises a friction wheel 14, which thus has a constant speed of rotation, and completes one revolution in one hour clockwise (in the figures SAM = clockwise).

Le mobile de came 456 comporte trois étages: la roue à friction 14, un plateau 15, et une came 16 qui porte un doigt excentré 160. Cette came 16 a pour fonction de manoeuvrer un entraîneur, ici un râteau pivotant 17, pour mouvoir la couronne 10 dans un sens ou dans l'autre. La roue à friction 14 entraîne le plateau 15 via la friction exercée par exemple sur une portée arbrée 152 du plateau 15 par des lames flexibles que comporte la roue à friction 14 et qui délimitent une fente 140. Le plateau 15 entraîne le doigt 160 de la came 16 via une ganse 151 que comporte ce plateau 5, notamment une ganse en arc de cercle concentrique à ce plateau 15.The mobile cam 456 comprises three stages: the friction wheel 14, a plate 15, and a cam 16 which carries an eccentric finger 160. This cam 16 has the function of maneuvering a driver, here a pivoting rake 17, to move the crown 10 in one direction or the other. The friction wheel 14 drives the plate 15 via the friction exerted for example on a shaft bearing 152 of the plate 15 by flexible blades that the friction wheel 14 comprises and which delimit a slot 140. The plate 15 drives the finger 160 of the cam 16 via a loop 151 that this plate 5 comprises, in particular a loop in the form of an arc of a circle concentric with this plate 15.

La friction permet le réglage précis de l'instant du saut de la couronne 10, et la ganse 151 permet un saut franc du râteau 17 qui interagit avec la came 16.The friction allows the precise adjustment of the moment of the jump of the crown 10, and the strap 151 allows a free jump of the rake 17 which interacts with the cam 16.

Le râteau 17, contraint par un ressort de râteau 18, prend l'information sur la périphérie de la came 16, et la transmet à la couronne 10 par un engrènement de la denture intérieure 107 de la couronne 10 avec la denture de râteau 170. Plus particulièrement, la couronne 10 pivote autour de la platine 5 grâce à des galets de couronne 19 qui guident un alésage de couronne 119.The rake 17, forced by a rake spring 18, takes the information on the periphery of the cam 16, and transmits it to the crown 10 by meshing of the internal toothing 107 of the crown 10 with the rake toothing 170. More in particular, crown 10 pivots around plate 5 thanks to crown rollers 19 which guide a crown bore 119.

La couronne 10 effectue donc un saut instantané depuis sa position armée vers sa position désarmée(sur les figures SIAM : sens inverse des aiguilles d'une montre), pour ensuite revenir lentement en sens contraire (sur les figures SAM : sens des aiguilles d'une montre) en position armée, et ce cycle se répète périodiquement, par exemple toutes les heures dans le mécanisme illustré par les figures ; naturellement cette périodicité dépend du type d'affichage, et la période serait différente pour un affichage de l'âge de la lune, par exemple.The crown 10 therefore performs an instantaneous jump from its armed position to its disarmed position (in the SIAM figures: anti-clockwise direction), to then return slowly in the opposite direction (in the SAM figures: clockwise direction). a watch) in the armed position, and this cycle is repeated periodically, for example every hour in the mechanism illustrated by the figures; naturally this periodicity depends on the type of display, and the period would be different for a display of the age of the moon, for example.

La figure 4 montre le système d'entraînement de couronne en position armée, le râteau 17 comporte un palpeur 171 qui est en appui sur un bec que comporte la came 16 sur son plus grand rayon, à la limite entre un limaçon 161 et un front 162, notamment un front sensiblement droit, destiné à provoquer le saut.There figure 4 shows the crown drive system in the armed position, the rake 17 comprises a feeler 171 which bears on a beak which the cam 16 comprises over its largest radius, at the limit between a cochlea 161 and a front 162, in particular a noticeably straight forehead, intended to cause the jump.

La figure 6 montre le système d'entraînement de couronne en position désarmée ; le palpeur 171 est en appui sur le plus petit rayon du limaçon 161, juste après avoir franchi le front 162.There figure 6 shows the crown drive system in the decocked position; the feeler 171 rests on the smallest radius of the cochlea 161, just after having crossed the front 162.

La figure 8 illustre le mécanisme complet de croix de Malte à saut instantané selon l'invention, qui combine les deux sous-systèmes énoncés précédemment. Les roues satellites 8 sont entraînées par les bras 7 de l'étoile 4, et tournent à vitesse constante autour de la platine 5. Lorsque qu'une roue satellite 8 arrive en position à six heures, la couronne 10 lui impose un demi-tour sur elle-même de manière instantanée. Pour rappel, la roue satellite 8 est en rotation constante autour de la platine 5 par l'étoile 4, et elle est guidée angulairement par la platine 5.There figure 8 illustrates the complete instantaneous jump Maltese cross mechanism according to the invention, which combines the two subsystems set out above. The planet wheels 8 are driven by the arms 7 of the star wheel 4, and rotate at constant speed around the plate 5. When a planet wheel 8 arrives in position at six o'clock, the crown 10 imposes a half turn on it on itself instantly. As a reminder, the planet wheel 8 is in constant rotation around the plate 5 by the star 4, and it is angularly guided by the plate 5.

Les séquences du saut instantané des roues satellites 8 sont les suivantes :

  • position d'approche, tel que visible sur la figure 9 : la roue satellite 8 est entraînée par l'étoile 4, et est guidée en glissement par la couronne 10, laquelle est en position armée ;
  • position avant saut, tel que visible sur la figure 10 : la roue satellite 8 est en position à six heures d'une pièce d'horlogerie, notamment une montre, cette position particulière n'étant nullement limitative ; la couronne 10 guide la roue satellite 8 ; la couronne 10 est encore en position armée ;
  • saut, décomposé sur les figures 11 à 14, qui montrent la permutation des évidements 821 et 822 au cours de la manoeuvre de demi-tour, et dans cet ordre ; la roue satellite 8 est toujours en position à six heures, la couronne 10 est à présent en rotation, elle passe de la position armée à la position désarmée, et vient, lors de sa course engrener avec la roue satellite 8 pour lui imprimer un demi-tour ; la roue satellite 8 a effectué un demi-tour instantanément sur elle-même ; la dent 811 est passée dans le premier évidement 1801 de la couronne 10, puis la deuxième dent 812 dans le deuxième évidement 1803 après la première dent 1802 de couronne, puis la troisième dent 813 dans le troisième évidement 1805 après la deuxième dent 1804 de couronne, laissant le deuxième évidement 822 de mobile venir progressivement vers la portée cylindrique 9, c'est-à-dire que les flancs latéraux des dents 813 et 814 vienne glisser sur cette portée 9 ;
  • position après le saut, tel que visible sur la figure 15 : la roue satellite 8 est guidée par la couronne 10, et, entraînée par l'étoile 4, elle quitte la position à six heures, et est guidée par ses dents 813 et 814, qui encadrent son deuxième évidement 822, sur la portée cylindrique 9 de la couronne 10. La couronne 10 revient alors de sa position désarmée à sa position armée, mais ce mouvement est effectué plus lentement que l'avancement de l'étoile 4, pour ne pas interférer sur l'opération en cours avec la roue satellite 8, mais avec le décalage convenable pour être prêt à faire sauter instantanément la prochaine roue satellite, qui se présentera une heure plus tard.
The sequences of the instantaneous jump of the satellite wheels 8 are as follows:
  • approach position, as seen on the figure 9 : the satellite wheel 8 is driven by the star wheel 4, and is guided in sliding by the crown 10, which is in the armed position;
  • pre-jump position, as seen on the figure 10 : the satellite wheel 8 is in the six o'clock position of a timepiece, in particular a watch, this particular position not being limiting in any way; crown 10 guides satellite wheel 8; crown 10 is still in the cocked position;
  • jump, broken down on the figures 11 to 14 , which show the permutation of recesses 821 and 822 during the U-turn maneuver, and in this order; the satellite wheel 8 is still in position at six o'clock, the crown 10 is now in rotation, it passes from the armed position to the disarmed position, and comes, during its race, to mesh with the satellite wheel 8 to give it a half turn; the satellite wheel 8 has performed an instantaneous U-turn on itself; the tooth 811 has passed into the first recess 1801 of the crown 10, then the second tooth 812 into the second recess 1803 after the first crown tooth 1802, then the third tooth 813 into the third recess 1805 after the second crown tooth 1804 , leaving the second mobile recess 822 to come progressively towards the cylindrical bearing surface 9, that is to say that the lateral flanks of the teeth 813 and 814 come to slide on this bearing surface 9;
  • position after the jump, as seen on the figure 15 : the satellite wheel 8 is guided by the crown 10, and, driven by the star 4, it leaves the position at six o'clock, and is guided by its teeth 813 and 814, which frame its second recess 822, on the cylindrical surface 9 of the crown 10. The crown 10 then returns from its disarmed position to its armed position, but this movement is carried out more slowly than the advancement of the star 4, so as not to interfere with the operation in progress with the wheel satellite 8, but with the proper offset to be ready to instantly jump the next satellite wheel, which will show up an hour later.

L'invention présente des avantages conséquents. Elle permet surtout de réaliser le saut instantané d'un mécanisme à croix de Malte. La réalisation d'un tel saut instantané impacte directement l'affichage, et assure la sécurité de lecture pour l'utilisateur. L'indicateur passe d'une position à une autre de manière franche, sans position intermédiaire ; par exemple le changement AM/PM à douze heures. Ainsi l'utilisateur perçoit une information dont la lecture claire est précise et sans ambiguïté.The invention has substantial advantages. Above all, it makes it possible to perform the instantaneous jump of a Maltese cross mechanism. Performing such an instantaneous jump directly impacts the display, and ensures reading security for the user. The indicator passes from one position to another frankly, without intermediate position; for example the AM/PM change at twelve o'clock. Thus the user perceives information whose clear reading is precise and unambiguous.

Le mécanisme selon l'invention tolère un réglage en arrière, par exemple lors d'une mise à l'heure ou similaire, avec un défaut de synchronisation du moment du saut.The mechanism according to the invention tolerates backward adjustment, for example when setting the time or the like, with a fault in synchronization of the moment of the jump.
