Description

La présente invention concerne un mouvement d'horlogerie munie d'un mécanisme de calendrier à quantième perpétuel, comportant un dispositif d'entraínement d'un indicateur de quantième, ce dispositif comprenant un entraíneur pouvant faire avancer l'indicateur par saut une fois toutes les 24 heures.The present invention relates to a motion with a calendar mechanism to perpetual calendar, comprising a device of a date indicator, this device including a coach who can advance the indicator by jumping once every 24 hours.

Ce mouvement comprend en outre un dispositif de rattrapage permettant de faire effectuer à cet indicateur des pas de rattrapage supplémentaires, pour tenir compte automatiquement des mois à 28, 29, ou 30 jours.This movement further comprises a device for catching up for this indicator additional catch-up steps, to take into account automatically months to 28, 29, or 30 days.

Plus particulièrement, et de façon avantageuse, ce mouvement est conçu pour pouvoir s'adapter facilement sur un mouvement comprenant un dispositif d'entraínement d'un indicateur de quantième classique.More particularly, and advantageously, this movement is designed to easily fit on a movement comprising a drive device of a classic date indicator.

En outre, le mouvement selon l'invention permet l'affichage d'indications complémentaires journalières, mensuelles et/ou annuelles, sans apporter de modifications majeures au mouvement.In addition, the movement according to the invention allows displaying additional daily indications, monthly and / or annual, without any modifications major to movement.

On connaít déjà du brevet suisse CH 574 125 un mécanisme de commande d'un calendrier semi-perpetuel comprenant un disque de quantième dont une bascule unique effectue l'avance intermédiaire journalière et la correction, à la fin de certains mois, à l'aide d'un mécanisme. Cette correction est réalisée à l'aide d'un mécanisme comprenant une came des mois en liaison avec un dispositif de verrouillage du disque de quantième. Un tel mécanisme présente l'inconvénient d'être complexe et coûteux à mettre en oeuvre.We already know Swiss patent CH 574 125 a mechanism of ordering a semi-perpetual calendar including a date disc including a single flip-flop makes the daily intermediate advance and the correction, at the end of some months, using a mechanism. This correction is carried out using a mechanism comprising a cam of months in connection with a locking device of the date disc. Such mechanism has the disadvantage of being complex and expensive to implement.

Par ailleurs, ce mécanisme est semi-perpétuel, c'est-à-dire qu'il ne tient pas compte des années bissextiles et il nécessite l'utilisation d'un mécanisme d'affichage journalier et de correction mensuel.Moreover, this mechanism is semi-perpetual, that is to say that it does not account for leap years and it requires the use of a display mechanism daily and monthly correction.

On connaít par ailleurs du brevet EP 0 052 070 un dispositif d'entraínement perpétuel du disque de quantième, comportant une came des mois et une came des années pour réaliser la correction requise de l'affichage à la fin des mois de moins de 31 jours. Cette construction est compliquée et ne peut pas s'adapter sur un mouvement comportant un dispositif d'affichage du quantième traditionnel. En outre, ce système ne permet pas l'affichage d'indications complémentaires à l'indication du quantième, telles que l'indication du jour, des mois et de l'année bissextile.EP 0 052 070 discloses a perpetual drive device of the disc of date, including a cam of the months and a cam of years to achieve the required correction of the display at the end of the months of less than 31 days. This construction is complicated and can not fit on a move having a date display device traditional. In addition, this system does not allow the display of additional indications to the indication date, such as the indication of the day, months and of the leap year.

Le brevet suisse CH 169 64 décrit un mécanisme qui ne tient pas compte des années bissextiles et qui comprend un système à cames à encoches variables de petites dimensions, disposées entre le centre du mouvement et sa périphérie. Les faibles dimensions de ce système à cames ne permet pas d'obtenir une précision satisfaisante.Swiss patent CH 169 64 describes a mechanism which does not ignores leap years and that includes a Variable slot cam system of small size dimensions, arranged between the center of the movement and its periphery. The small dimensions of this cam system does not provide satisfactory accuracy.

Ainsi, la présente invention a pour but de remédier aux inconvénients de l'art antérieur susmentionné, en fournissant un mouvement d'horlogerie à quantième perpétuel, qui peut s'adapter facilement sur un mouvement comprenant déjà un dispositif d'affichage du quantième classique, qui offre une grande précision de fonctionnement et qui, en outre, permet l'affichage d'indications complémentaires à celles du quantième, telles que l'indication du mois et/ou des années bissextiles et non bissextiles, ainsi qu'un affichage 24h permettant l'initialisation après l'arrêt de la montre.Thus, the present invention aims to remedy disadvantages of the aforementioned prior art, providing a watchmaking movement with a date perpetual, which can easily adapt to a movement already including a date display device classic, which offers great accuracy of functioning and which, in addition, allows the display additional indications to those of the date, such as the indication of the month and / or years leap and non-leap, as well as a 24h display allowing initialization after stopping the watch.

A cet effet, l'invention a pour objet un mouvement d'horlogerie muni d'un mécanisme de calendrier à quantième perpétuel, comportant un dispositif d'entraínement d'un indicateur de quantième, ce dispositif comprenant des moyens d'entraínement pouvant faire avancer ledit indicateur par saut une fois toutes les 24 heures. Ce mouvement est caractérisé en ce qu'il comporte en outre un dispositif de rattrapage permettant de faire effectuer à cet indicateur des pas de rattrapage supplémentaires, pour tenir compte automatiquement des mois à 28, 29, ou 30 jours, ce dispositif comportant une came rotative entraínée d'au moins un pas toutes les 24 heures, cette came ayant un profil apte à piloter un palpeur provoquant:

  • d'une part, le mouvement oscillant d'un équipage mobile muni d'un système à cliquet, pour faire avancer l'indicateur de quantième du ou des pas de rattrapage supplémentaires requis, et
  • d'autre part, l'avancement de ladite came pour lui faire effectuer un nombre de pas égal au nombre de pas de rattrapage dudit indicateur afin de lui faire effectuer un tour complet par année.
For this purpose, the subject of the invention is a watch movement provided with a perpetual calendar calendar mechanism, comprising a device for driving a date indicator, this device comprising drive means capable of advancing said flag by jumping once every 24 hours. This movement is characterized in that it further comprises a retrofit device making it possible to make this indicator take additional retrofit steps, to automatically take account of the months at 28, 29, or 30 days, this device comprising a rotary cam driven at least one step every 24 hours, this cam having a profile capable of driving a feeler causing:
  • on the one hand, the oscillating movement of a mobile unit equipped with a ratchet system, to advance the date indicator of the additional step (s) required, and

En se référant désormais à la figure 8, on décrira ci-après le mouvement selon l'invention, qui est désigné par la référence générale 1.Referring now to Figure 8, we will describe hereinafter the movement according to the invention, which is designated by the general reference 1.

Le mouvement 1 comprend un mécanisme de calendrier à quantième perpétuel comportant un disque de quantièmes 2 qui porte des indications des quantièmes 4. Ces indications apparaissent dans un guichet 6 d'un cadran, non représenté.Motion 1 includes a calendar mechanism to perpetual calendar comprising a date disc 2 which carries indications of the dates 4. These indications appear in a window 6 of a dial, not shown.

Le disque 2 est associé à un dispositif d'entraínement 8 comportant des moyens d'entraínement constitués d'un bras élastique 10 solidaire d'une roue de 24 heures référencée 12. La roue 12 est en prise avec un mobile 14, engrenant avec une roue du canon des heures 16, qui fait un tour en douze heures.Disk 2 is associated with a device 8 having drive means constituted by an elastic arm 10 integral with a wheel of 24 hours referenced 12. The wheel 12 is engaged with a mobile 14, meshing with a clock wheel of hours 16, who goes around in twelve hours.

Le bras élastique 10 comprend à son extrémité libre un crochet 18 prévu pour venir s'engager dans une denture intérieure 22 du disque 2, afin de faire avancer le disque des quantièmes 2 une fois par 24 heures, lorsque le crochet 18 vient en prise sur une dent de cette denture 22.The elastic arm 10 comprises at its free end a hook 18 provided to engage in teeth 22 of the disc 2, to advance the disc 2 days once every 24 hours, when the hook 18 engages on a tooth of this toothing 22.

Un ressort sautoir 24 maintient en position fixe le disque 2, jusqu'à ce que le crochet 18, entraíné en rotation par la roue 12, vienne s'engager sur la dent, par exemple D1, et arme le bras élastique 10, jusqu'à ce qu'il surmonte la force du ressort sautoir 24 et déplace, de façon quasi instantanée, le disque de quantième 2 d'un saut pour le passage d'un quantième au quantième suivant.A jumper spring 24 maintains in a fixed position the disc 2, until the hook 18, driven in rotation by the wheel 12, come engage on the tooth, by example D1, and arm the elastic arm 10, until it overcomes the force of the jumper spring 24 and moves, almost instantaneously, the date disk 2 of a jump for the transition from a date to the next date.

On notera que le dispositif 8 est conçu de sorte qu'après le passage au quantième suivant, comme expliqué ci-dessus, le crochet 18 se dégage de la denture 22 pour permettre, le cas échéant, un avancement supplémentaire du disque 2 afin de lui faire effectuer un ou plusieurs pas de rattrapage et pour tenir compte des mois ayant moins de 31 jours, à l'aide d'un dispositif de rattrapage qui sera décrit ci-après.Note that the device 8 is designed so after the changeover to the next day, as explained above, the hook 18 emerges from the toothing 22 to allow, where appropriate, further advancement of the disk 2 to make it take one or more steps catch-up and to take into account months with less than 31 days, using a catch-up device that will be described below.

Le dispositif d'entraínement 8 est un dispositif classique qui ne sera pas décrit de façon plus détaillée.The training device 8 is a device classic that will not be described in more detail.

Selon l'invention, le mouvement 1 comporte un dispositif de rattrapage pourvu d'une came rotative 26 entraínée d'au moins un pas toutes les 24 heures et effectuant un tour complet par année.According to the invention, the movement 1 comprises a catch-up device provided with a rotary cam 26 driven at least one step every 24 hours and performing a full turn per year.

La came 26 est guidée en rotation, par exemple à la surface du mouvement, par des moyens non représentés et elle présente un profil 28 destiné à piloter un palpeur 30.The cam 26 is guided in rotation, for example at the surface of the movement, by means not shown and it has a profile 28 intended to drive a feeler 30.

Le palpeur 30 commande, d'une part, le mouvement oscillant d'un équipage mobile 32 qui est muni d'un système à cliquet 34 destiné à faire avancer le disque 2 du ou des pas de rattrapage requis.The probe 30 controls, on the one hand, the movement oscillating of a mobile equipment 32 which is provided with a ratchet system 34 for advancing the disc 2 the required catch-up step (s).

Le palpeur 30 commande, d'autre part, l'avancement de la came 26 afin de lui faire effectuer un nombre de pas égal au nombre de pas de rattrapage du disque 2.The probe 30 controls, on the other hand, the advancement of the cam 26 to make it perform a number of steps equal to the number of retrofit steps of the disc 2.

La came 26 est entraínée par un train d'engrenage relié à la roue des heures 16. Plus précisément, la roue du canon des heures 16 (appelée ci-après roue des heures) porte un pignon 36 en prise avec la roue 38 d'un premier mobile. Ce premier mobile comporte un doigt 40 solidaire de la roue 38. Le rapport de démultiplication entre le pignon 36 et la roue 38 est tel que la roue 38 effectue un tour en 24 heures. Le doigt 40 coopère avec la denture d'une roue 42 à 31 dents, appartenant à un deuxième mobile dont le pignon 44 entraíne la came 26.The cam 26 is driven by a gear train connected to the hour wheel 16. More specifically, the wheel of the hours 16 canon (hereinafter referred to as the hour wheel) carries a pinion 36 engaged with the wheel 38 of a first mobile. This first mobile has a finger 40 integral wheel 38. The gear ratio between the pinion 36 and the wheel 38 is such that the wheel 38 performs a turn in 24 hours. The finger 40 cooperates with the teeth a wheel 42 to 31 teeth belonging to a second mobile whose pinion 44 drives the cam 26.

On notera que le doigt 40 est positionné au montage de sorte que ce dernier entre en contact avec la denture de la roue 42 après que le dispositif d'entraínement 8 ait permis le saut du disque 2.Note that the finger 40 is positioned at the assembly so that the latter comes into contact with the teeth of the wheel 42 after the training device 8 has allowed the jump of the disc 2.

La came 26 présente une forme annulaire entourant l'équipage mobile 32 et le dispositif d'entraínement 8. La came 26 et la roue des heures 16 ont un même axe de rotation R.The cam 26 has an annular shape surrounding the mobile equipment 32 and the training device 8. The cam 26 and the hour wheel 16 have the same axis of rotation R.

La came 26 présente une denture intérieure 46 qui coopère avec le pignon 44 pour l'entraínement en rotation de cette came.The cam 26 has an internal toothing 46 which cooperates with the pinion 44 for the rotational drive of this cam.

Le palpeur 30, qui a la forme générale d'une ancre, comprend un premier bras 48 qui repose, sous l'action d'un ressort de rappel 50, sur le profil 28 de la came 26 par une levée 52.The probe 30, which has the general shape of an anchor, includes a first arm 48 which rests, under the action of a return spring 50, on the profile 28 of the cam 26 by a lift 52.

La levée 52, qui est en contact permanent avec le profil de la came 26, présente une forme semi-sphérique et est disposée au voisinage de l'extrémité libre du bras 48. Cette levée 52 est réalisée de préférence en rubis synthétique.The lift 52, which is in permanent contact with the profile of the cam 26, has a semi-spherical shape and is disposed in the vicinity of the free end of the arm 48. This lift 52 is preferably made of ruby synthetic.

Le palpeur 30 comprend un deuxième bras 54 qui est relié au premier bras 48 par une partie de jonction 56. Ce deuxième bras 54 est accouplé à l'équipage mobile 32 par son extrémité libre qui a la forme d'une fourche 58 dont les dents sont engagées, dans l'exemple représenté, sur une goupille 60 solidaire de l'équipage mobile 32.The probe 30 comprises a second arm 54 which is connected to the first arm 48 by a joining portion 56. This second arm 54 is coupled to the mobile assembly 32 by its free end which has the shape of a fork 58 whose the teeth are engaged, in the example shown, on a pin 60 secured to the moving assembly 32.

Le palpeur 30 comprend un troisième bras 62 s'étendant, depuis la partie de jonction 56, sensiblement dans le prolongement du premier bras 48 et dont l'extrémité coopère avec le ressort 50 afin de pousser la levée 52 en direction du profil de la came 26.The probe 30 comprises a third arm 62 extending from the joining portion 56, substantially in the extension of the first arm 48 and the end cooperates with the spring 50 to push the lifting 52 towards the profile of the cam 26.

Pour ce faire, le palpeur 30 est monté pivotant par sa partie de jonction 56, via un axe 64, sur le mouvement, par exemple sur une platine (non représentée).To do this, the probe 30 is pivotally mounted by its junction part 56, via an axis 64, on the movement, for example on a plate (not shown).

L'axe 64 du palpeur 30 est associé à un excentrique 66 qui permet l'ajustement final de la levée 52 par rapport au profil 28 de la came 26.The axis 64 of the probe 30 is associated with an eccentric 66 which allows the final adjustment of the lift 52 by relative to the profile 28 of the cam 26.

Dans l'exemple représenté, le palpeur 30 et le ressort 50 s'étendent généralement sous la came 26.In the example shown, the probe 30 and the spring 50 generally extend under the cam 26.

L'équipage mobile 32 est également associé à un levier mobile 68 qui est articulé par l'une des ses extrémités libres sur la goupille 60, ce levier 68 étant commandé par le palpeur 30. L'autre extrémité libre du levier 68 présente un bec 70 en prise avec une roue 72 à dents de loup. Cette roue 72 est solidaire de la roue 44 appartenant au mobile entraínant la came 26. Le levier 68 est maintenu en prise avec la roue 72 par l'intermédiaire d'un ressort à lame 74 qui appuie latéralement sur le dos du bec 70, dans une direction radiale de la roue 72.The mobile equipment 32 is also associated with a mobile lever 68 which is articulated by one of his free ends on the pin 60, this lever 68 being controlled by the probe 30. The other free end of the lever 68 has a spout 70 engaged with a wheel 72 to Wolf teeth. This wheel 72 is secured to the wheel 44 belonging to the mobile driving the cam 26. The lever 68 is kept in engagement with the wheel 72 via a leaf spring 74 which bears laterally on the back of the nose 70, in a radial direction of the wheel 72.

Par ailleurs, on précisera que les roues 72 et 42 qui appartiennent au mobile entraínant la came 26 sont maintenues en position, entre chaque pas, par un sautoir 76, sollicité par un ressort 78.In addition, it will be specified that the wheels 72 and 42 which belong to the mobile driving the cam 26 are held in position, between each step, by a jumper 76, biased by a spring 78.

L'équipage 32 comporte une plaque de base 80 montée à rotation autour de l'axe R, autour de la roue des heures 16. La plaque de base 80 s'étend depuis le centre du mouvement en direction radiale, vers le disque 2. Cette plaque 80 porte le cliquet 34 qui est monté à rotation sur cette plaque par l'intermédiaire d'un pivot 82.The crew 32 comprises a base plate 80 mounted at rotation around the R axis, around the hour wheel 16. The base plate 80 extends from the center of the radial direction towards disk 2. This plate 80 carries the ratchet 34 which is rotatably mounted on this plate via a pivot 82.

Le cliquet 34 est constitué, d'une part, d'un bec 84 destiné à venir s'engager dans la denture 22 du disque 2 et, d'autre part, d'un bras élastique 86 qui s'étend au dessus de la plaque 80. Dans cet exemple, le bras 86 s'étend en direction du centre du mouvement.The pawl 34 consists, on the one hand, of a spout 84 intended to engage in the toothing 22 of the disc 2 and, on the other hand, an elastic arm 86 which extends above the plate 80. In this example, the arm 86 extends towards the center of the movement.

Le cliquet 34 comporte, en outre, un ressort 88 agissant sur le bec 84 pour le faire pénétrer dans la denture 22 du disque 2. Dans l'exemple illustré, le ressort 88 a la forme -générale d'un L qui entoure partiellement le pivot 82 et dont une branche s'appuie contre un flanc du bec 84, tandis que l'autre branche s'appuie contre un axe 90 solidaire de la plaque 80.The pawl 34 further comprises a spring 88 acting on the beak 84 to get it into the Toothing 22 of the disk 2. In the illustrated example, the spring 88 has the general shape of an L that surrounds partially pivot 82 and a branch is based against one side of the beak 84, while the other branch leans against an axis 90 secured to the plate 80.

L'axe 90 porte une roue de 24 heures référencée 92, qui engrène avec un pignon 94, solidaire du canon des heures. L'axe 90 porte également une came inertielle 96 qui est entraínée par la roue 92, cette came inertielle 96 coopérant périodiquement avec l'extrémité du bras 86 pour bloquer ce bras 86 contre une goupille 98, également portée par la plaque de base 80.The axis 90 carries a 24-hour wheel referenced 92, which meshes with a pinion 94, integral with the barrel of hours. Axis 90 also carries an inertial cam 96 which is driven by the wheel 92, this inertial cam 96 periodically cooperating with the end of the arm 86 to block this arm 86 against a pin 98, also carried by the base plate 80.

Comme on le comprendra de la description du fonctionnement détaillé du mouvement selon l'invention, cet agencement constitue un système de blocage permettant, tous les deux mois, de bloquer le déplacement du bras 86 du cliquet 34 pour le condamner au moment du ou des sauts de rattrapage. Ainsi, ce système de blocage maintient, dans une première position, le bec 84 de façon quasiment fixe pour que ce bec 84 assure l'entraínement du disque 2. Dans une deuxième position, ce système de blocage libère le bec 84 pour qu'il assure sa fonction de cliquet, vis-à-vis du disque 2, lorsque ce disque 2 est actionné, notamment par le dispositif d'entraínement 8.As will be understood from the description of detailed operation of the movement according to the invention, this arrangement constitutes a locking system allowing, every two months, to block the movement of the arm 86 ratchet 34 to condemn it at the time of the jump (s) catching up. Thus, this locking system maintains, in a first position, the nozzle 84 almost fixed for this spout 84 provides drive disk 2. In a second position, this locking system releases the spout 84 to ensure its function of ratchet, vis-à-vis of disk 2, when this disk 2 is actuated, in particular by the driving device 8.

Le profil 28 de la came 26 est formé de cinq secteurs contigus référencés I à V reliés entre eux par des décrochements formant des encoches E1 à E5. La profondeur des encoches E1 à E5 détermine le déplacement radial du palpeur 30, et notamment le déplacement radial de la levée 52 pour faire effectuer au disque 2 le nombre de pas de rattrapage requis à la fin des mois ayant moins de 31 jours.The profile 28 of the cam 26 is formed of five sectors contiguous referenced I to V interconnected by recesses forming notches E1 to E5. The depth notches E1 to E5 determines the radial displacement of the probe 30, and in particular the radial displacement of the lift 52 to make disk 2 perform the number of steps of catch-up required at the end of the month with less than 31 days.

Les cinq secteurs I à V forment des rampes continues R1 à R5 qui s'étendent, dans le sens anti-horaire. Ces rampes R1 à R5 s'étendent du fond d'une encoche En jusqu'au sommet d'une encoche suivante En+1, à partir d'un premier rayon jusqu'à un deuxième rayon supérieur au premier.The five sectors I to V form continuous ramps R1 to R5 extending in the counterclockwise direction. These ramps R1 to R5 extend from the bottom of a notch to the top of a next notch En + 1, from a first ray to a second radius greater than first.

L'une des encoches, référencée E3, présente une. profondeur plus grande que celle des quatre autres encoches E1, E2, E4, E5, ces dernières ayant des profondeurs égales les unes aux autres.One of the notches, referenced E3, presents a. depth greater than that of the other four notches E1, E2, E4, E5, the latter having depths equal to each other.

Les encoches E1, E2, E4 et E5 ont des profondeurs telles qu'elles peuvent faire déplacer le palpeur 30 pour commander, via l'équipage mobile 32, le déplacement du disque 2 d'un pas de rattrapage à la fin de mois à 30 jours (avril, juin, septembre, novembre), tandis que l'encoche E3 a une profondeur telle qu'elle peut faire déplacer le palpeur 30 pour commander également via l'équipage mobile 32, le déplacement du disque 2 de deux ou de trois pas de rattrapage, respectivement à la fin des mois de 29 et 28 jours (février, bissextile et non-bissextile).Notches E1, E2, E4 and E5 have depths such that they can move the probe 30 to order, via the mobile equipment 32, the displacement of disc 2 of a catch-up at the end of the month at 30 days (April, June, September, November), while the notch E3 has a depth such that it can make move the probe 30 to also control via the moving equipment 32, the displacement of the disc 2 of two or three catch-up steps, respectively at the end of months of 29 and 28 days (February, leap and non-leap).

A cet effet, la profondeur de l'encoche E3 n'est pas constante. L'encoche E3 est associée à un système référencé 100, capable de faire varier sa profondeur une fois tous les quatre ans. Ce système 100 visible à la figure 13, est constitué d'un volet mobile 102 monté à rotation sur la came 26 par l'intermédiaire d'un axe 104. L'axe 104 porte une roue 106 faisant un tour tous les quatre ans, cette roue étant donc actionnée, à chaque rotation complète de la came d'un quart de tour. A cet effet, le système 100 coopère une fois par année avec un doigt fixe du mouvement, référencé 108. Grâce à cet agencement, le volet mobile 102 peut venir obturer une fois tous les quatre ans l'encoche E3 afin de diminuer sa profondeur. Cela permet de limiter le déplacement du palpeur 30 pour que ce dernier ne fasse effectuer au disque 2 que deux pas de rattrapage à la fin des mois de février des années bissextiles.For this purpose, the depth of the notch E3 is not constant. The E3 notch is associated with a system referenced 100, able to vary its depth a once every four years. This system 100 visible to the FIG. 13, consists of a movable flap 102 mounted at rotation on the cam 26 via an axis 104. The axis 104 carries a wheel 106 making a turn every four years, this wheel being operated, at each complete rotation of the cam a quarter of a turn. In this Indeed, the system 100 cooperates once a year with a fixed finger of the movement, referenced 108. Thanks to this arrangement, the movable flap 102 can close off a once every four years the E3 notch to reduce its depth. This limits the movement of the feeler 30 so that the latter does not make disc 2 that two no catch-up at the end of the months of February leap years.

En outre, le volet 102 comporte un rebord qui, lorsque le volet vient une fois obturer l'encoche E3, rallonge la longueur de la rampe R3 d'une distance correspondant à un jour.In addition, flap 102 has a flange which, when the flap comes once closing the notch E3, extends the length of the ramp R3 by a distance corresponding to a day.

La roue 106 est maintenue en position par un sautoir 110 en forme de L, monté à rotation à l'aide d'un pivot 112 qui est supporté par une couronne 116 formant un disque des mois et solidaire de la came .The wheel 106 is held in position by a jumper 110 L-shaped, rotatably mounted with a pivot 112 which is supported by a crown 116 forming a disc of the months and solidarity of the cam.

Ce sautoir 110 coopère avec un ressort de rappel 114 qui agit sur l'une des branches du L pour que l'autre branche vienne pénétrer entre deux dents de la roue 106, cette deuxième branche ayant une extrémité prévue à cet effet. Ainsi, le sautoir 110 et son ressort 114 tournent avec la came 26 à raison d'un tour complet par année.This jumper 110 cooperates with a return spring 114 which acts on one of the branches of the L so that the other branch comes between two teeth of the wheel 106, this second branch having an end provided for this effect. Thus, the jumper 110 and its spring 114 turn with cam 26 at the rate of one complete revolution per year.

On a également représenté à la figure 13 un dispositif d'indication des années bissextiles 120 qui peut équiper de façon avantageuse le mouvement 1. FIG. 13 also shows a leap year indication device 120 which can advantageously equip the movement 1.

Le dispositif 120 comprend une étoile 122 portant une aiguille d'indication annuelle (non représentée), cette aiguille étant pivotée sur le mouvement 1. L'étoile 122 est maintenue par un ressort sautoir 124, assurant le positionnement de l'aiguille. Dans l'exemple représenté, l'étoile 122 comporte huit branches et est entraínée par deux dents d'entraínement 126 solidaires de la came 26. Ainsi, l'étoile 122 est commandée, une fois par année, par les deux dents pour effectuer un quart de tour à chaque rotation complète de la came. Cette indication est précieuse pour la mise en évidence de l'année bissextile.The device 120 comprises a star 122 carrying a annual indication needle (not shown), this needle being rotated on the movement 1. The star 122 is maintained by a jumper spring 124, ensuring the positioning of the needle. In the example shown, the star 122 has eight branches and is driven by two drive teeth 126 integral with the cam 26. Thus, the star 122 is ordered, once a year, by both teeth to perform a quarter turn at each complete rotation of the cam. This indication is valuable for highlighting the leap year.

En référence aux figures 1 à 15, on décrira ci-après le fonctionnement du mouvement selon l'invention.With reference to FIGS. 1 to 15, will be described below the operation of the movement according to the invention.

A la figure 1, on voit le dispositif d'entraínement du quantième classique à 21 heures, soit au début de son armage pour le déclenchement d'un saut usuel, au passage du 12 au 13 du mois.In Figure 1, we see the drive device of the classical date at 9 pm, at the beginning of his arming for the triggering of a usual jump, in passing from the 12th to the 13th of the month.

Le crochet 18 du bras élastique 10 vient buter contre une dent D1 de la denture 22. La levée 52 est en cours de montée sur la rampe R5. La came inertielle 96 n'a pas atteint l'extrémité du bras 86 du cliquet 34. Le bec 84 peut donc monter lentement sur le flanc d'une dent D2. Le cliquet 34 est donc libre et permet soit la fonction de passage futur du quantième, soit une remise à la date rapide au moyen d'un dispositif non décrit.The hook 18 of the elastic arm 10 abuts against a tooth D1 of the toothing 22. The lifting 52 is in progress climb on ramp R5. The inertial cam 96 does not have reaches the end of the arm 86 of the pawl 34. The spout 84 can therefore slowly climb on the side of a tooth D2. The ratchet 34 is therefore free and allows either the function of future passage of the date, a discount to the date fast by means of a device not described.

En outre, l'extrémité du doigt 40 n'a pas, à cet instant, encore atteint l'une des dents de la roue 42 à 31 dents.In addition, the end of the finger 40 does not have, at this moment, still reached one of the teeth of wheel 42 to 31 teeth.

A la figure 2, on voit le dispositif d'entraínement du quantième classique à 23 heures 30. Le bras élastique 10 des moyens d'entraínement a poursuivi son armage sans pour autant que le disque 2 n'ait encore bougé, ce dernier étant maintenu par le ressort sautoir 24. Les deux roues de 24 heures référencées respectivement 38 et 92 ont parcouru l'angle complémentaire correspondant au temps écoulé entre 21 heures et 23 heures 30, sans qu'aucune autre fonction ne se soit produite. In Figure 2, we see the drive device of the classic date at 11.30 pm The elastic arm 10 means of training continued without as long as the disc 2 has not moved yet, the latter being held by the jumper spring 24. Both wheels 24 hours referenced respectively 38 and 92 have traveled the complementary angle corresponding to the time between 9 pm and 11.30 pm, without any other function did not occur.

A la figure 3, on voit le dispositif d'entraínement du quantième classique à 24 heures, le disque 2 étant prêt à sauter d'un pas. Le crochet 18 a fait avancer le disque 2 durant la demi-heure précédent minuit. Le ressort sautoir 24 s'est soulevé durant cette courte période. Il retient encore le disque 2.In Figure 3, we see the drive device of the classical date at 24 hours, the disc 2 being ready to jump a step. Hook 18 advanced the disc 2 during the half-hour preceding midnight. The spring jumper 24 has risen during this short period. he still holds the disc 2.

A la figure 4, on voit le dispositif d'entraínement juste après le saut du disque 2, c'est-à-dire après le passage au 13 du mois. Le bras élastique 10 des moyens d'entraínement a retrouvé sa forme au repos. Le crochet 18 commence à se dégager de la denture 22 pour permettre la future rotation du disque 2, lors des fins de mois de moins de 31 jours.In Figure 4, we see the training device just after the jump of disk 2, that is after the passage to the 13th of the month. The elastic arm 10 means training has returned to its form at rest. The hook 18 starts to disengage from the toothing 22 to allow the future rotation of the disk 2, at the end of the month of less than 31 days.

A la figure 5, on voit l'état du mouvement après le saut susmentionné, à 2 heures du matin. Le crochet 18 du bras élastique 10 s'est complètement dégagé de la denture. 22. L'extrémité du doigt 40 entraíne une dent D3 de la roue 42 à 31 dents, jusqu'au moment où la force de rappel du sautoir 76 va être vaincue par l'entraínement du doigt 40 et va terminer la fonction d'entraínement de cette roue 42 sous l'action du ressort 78.In Figure 5, we see the state of the movement after the jump mentioned above, at 2 o'clock in the morning. The hook 18 of elastic arm 10 has completely cleared the teeth. 22. The end of the finger 40 causes a tooth D3 of the wheel 42 to 31 teeth, until the moment the force of recall jumper 76 will be defeated by the training of the finger 40 and will finish the drive function of this wheel 42 under the action of spring 78.

Le pignon 44 qui est solidaire de la roue 42 entraíne en rotation la came 26 par l'intermédiaire de la denture intérieure 70 de cette came. Ainsi, la came 26 qui est solidaire du disque 116 aura effectué un pas supplémentaire de 1/372ème de tour dans le sens horaire, faisant ainsi monter la levée 52 sur la rampe R5 en déplaçant lentement le palpeur 30 dans le sens anti-horaire, ce palpeur 30 entraínant dans sa course l'équipage mobile 32.The pinion 44 which is integral with the wheel 42 causes the cam 26 to rotate by means of the internal toothing 70 of this cam. Thus, the cam 26 which is secured to the disk 116 has made an additional step of 1/372 th of a turn in the clockwise direction, thereby raising the lift 52 on the ramp R5 by slowly moving the probe 30 in the counterclockwise direction , this probe 30 driving in its race the mobile equipment 32.

Au cours de cette période, la pointe du bec 84 est montée contre le flanc d'une dent D4 de la denture 22 du disque 2. Le bras 86 s'est déplacé angulairement autour de son axe 82, l'extrémité de ce bras étant poussée par la came inertielle 96 et sortant le bec 84 de la denture 22.During this period, the tip of beak 84 is mounted against the flank of a tooth D4 of the teeth 22 of the disc 2. The arm 86 has moved angularly around its axis 82, the end of this arm being pushed by the inertial cam 96 and out the spout 84 of the toothing 22.

L'extrémité de ce bras 86 se déplace jusqu'au moment où, par la rotation en 24 heures de la came inertielle 96, la came 96 laissera retomber le cliquet 34 dans la denture 22, sous l'effet du ressort 88. Durant toute cette période, le disque 2 a la liberté de tourner, notamment sous l'effet d'une mise à la date rapide.The end of this arm 86 moves until the moment where, by the rotation in 24 hours of the inertial cam 96, the cam 96 will drop the pawl 34 into the teeth 22, under the effect of the spring 88. During all this period, the disc 2 has the freedom to turn, especially under the effect of a quick update.

Le déplacement maximum du cliquet 34 étant atteint, dans cette configuration, vers 4 heures du matin, comme le montre la figure 6 qui présente à cet instant la position des autres mobiles en mouvement.The maximum displacement of the pawl 34 being reached, in this configuration, around 4 am, as the shows Figure 6 which shows at this moment the position other moving mobiles.

La figure 7 montre le mouvement dans les mêmes conditions que celles décrites précédemment à la figure 3, mais cette fois avant le pas de rattrapage du disque 2 pour le passage du 30 au 31 du mois, pour un mois de 30 jours.Figure 7 shows the movement in the same conditions than those previously described in Figure 3, but this time before the disc catch 2 for the passage from 30 to 31 of the month, for a month of 30 days.

Au cours de la période qui suit, la came inertielle 96 va venir se positionner devant l'extrémité du bras 86 pour le bloquer contre la goupille 98 et afin d'immobiliser le cliquet 34 par rapport à la plaque de base 80. A ce moment, le bec 84 du cliquet pénétre entièrement dans la denture 22 du disque 2.During the following period, the inertial cam 96 will come to stand in front of the end of the arm 86 to lock it against pin 98 and so to immobilize the pawl 34 relative to the plate of base 80. At this moment, the beak 84 of the ratchet penetrates entirely in the toothing 22 of the disc 2.

Parallèlement, le levier articulé 68 s'est déplacé lentement sous l'action du palpeur 30, via la goupille 60, pour monter sur la denture de la roue 72. Le bec 70 de ce levier est venu s'engager dans le creux suivant de la roue 72, sous l'effet du ressort 74.At the same time, articulated lever 68 has moved slowly under the action of the feeler 30, via the pin 60, to mount on the teeth of the wheel 72. The spout 70 of this lever came engage in the next trough of the wheel 72, under the effect of the spring 74.

On notera que la levée 52 repose toujours au bord de l'encoche E1 de la came 26 sur là rampe R1.Note that the lift 52 is still at the edge of the notch E1 of the cam 26 on the ramp R1.

Comme pour les figures 1 à 5, le dispositif d'entraínement 8 va s'armer et, aux alentours de minuit, va faire tourner le disque 2 pour le saut 30 au 31, comme on le voit sur la figure 8.As for Figures 1 to 5, the device training 8 will arm and, around midnight, will turn disk 2 for jump 30 to 31, as we see it in figure 8.

La figure 8 montre la situation du mouvement à 2 heures du matin, juste avant qu'il n'effectue le pas de rattrapage, du 31 au 1er.Figure 8 shows the situation of the movement at 2 in the morning, just before he takes the step of catching up, from the 31st to the 1st.

Le crochet 18 est complètement dégagé de la denture 22. A ce moment, le cliquet 34, et plus particulièrement son bec 84 est immobilisé sur la plaque de base 80 par la came inertielle 96 et la levée qui est au bord de l'encoche E1, est prête à tomber dans cette encoche.The hook 18 is completely clear of the teeth 22. At this moment, the ratchet 34, and more particularly its nozzle 84 is immobilized on the base plate 80 by the inertial cam 96 and the lift that is at the edge of the notch E1, is ready to fall into this notch.

Le doigt 40 entraíne alors la roue 42 d'un pas pour faire avancer la came 26 d'un pas correspondant. L'avance de la came 26 provoque la chute de la levée 52 dans l'encoche E1, sous l'effet du ressort 50. Dans sa course, le palpeur 30 déplace l'équipage mobile 32 en rotation, qui fait alors avancer le disque 2 d'un pas de rattrapage, grâce au bec 84 qui est immobilisé par la came inertielle 96 (figure 9) .The finger 40 then drives the wheel 42 a step to advancing the cam 26 with a corresponding step. The advance of the cam 26 causes the drop of the lift 52 in the notch E1, under the effect of the spring 50. In its race, the probe 30 moves the mobile assembly 32 in rotation, which then advances the disc 2 by a catch-up step, thanks to the nozzle 84 which is immobilized by the inertial cam 96 (Figure 9).

On notera à ce propos que lors du pas de rattrapage, l'inertie du disque 2 n'est pas maítrisable d'autant plus que l'énergie distribuée par le ressort 50 est variable en fonction de son armage, lui-même dépendant de la profondeur des encoches E1 à E5. La solution à ce problème consiste à bloquer le cliquet 32 par la came inertielle 96, comme mentionné ci-dessus. Ce blocage s'effectue au moment où le saut de rattrapage est effectué, ce qui maintient ainsi le bec 84 dans la denture 22 du disque 2.It should be noted in this regard that during the catch-up period, the inertia of disk 2 is not manageable even more that the energy distributed by the spring 50 is variable in function of its arming, itself dependent on the depth of the notches E1 to E5. The solution to this problem consists in blocking the pawl 32 by the inertial cam 96, as mentioned above. This blocking occurs at moment when the skip jump is made, which thus maintains the spout 84 in the toothing 22 of the disc 2.

Ainsi, après l'avance d'un pas du disque 2, la dent précédente D5 vient buter contre le talon du bec 84, empêchant ainsi le disque 2 de passer une dent supplémentaire.Thus, after advancing one step of the disc 2, the tooth previous D5 abuts against the heel of the beak 84, thus preventing the disc 2 from passing a tooth additional.

On précisera par ailleurs qu'étant donné que la came inertielle 96 tourne en permanence, le cliquet 32 est libre la majeure partie du temps et notamment lors du passage du quantième traditionnel à minuit. Toutefois, si un changement rapide de date devait intervenir au moment où la came bloque le bras élastique 86, notamment entre la période qui suit le saut traditionnel à minuit et le saut de rattrapage en fin de mois, le bras élastique 8G a la souplesse nécessaire pour faire passer une ou plusieurs dents de la denture 22 par dessus la pointe du cliquet 84.It will be specified that since the cam inertial 96 rotates continuously, the ratchet 32 is free most of the time and especially during the transition from the traditional date to midnight. However, if a quick change of date was to occur at the moment where the cam blocks the elastic arm 86, in particular between the period following the traditional jump at midnight and the jump catch-up at the end of the month, the 8G elastic arm has the flexibility to pass one or more teeth of the toothing 22 over the ratchet tip 84.

Pour commenter davantage ce qui précède, on précisera qu'au cours des jours successifs des mois à 31 jours, la levée 52 monte progressivement le long d'une des rampes R1 à R5 de la came 26. Durant ce trajet qui représente, dans le cas de la rampe R1, l'intervalle entre deux mois, le ressort 50 a été progressivement bandé par le bras 62 du palpeur 30 et a armé le palpeur 30 pour qu'il tombe dans l'encoche E1, lorsque le doigt 40 aura commandé le déplacement de la came 26. Lorsque le palpeur 30 progresse le long de la rampe R1, il pivote autour de son axe 64 et entraíne par là-même un déplacement angulaire de l'équipage mobile 32, via la goupille 60. Lorsque le palpeur 30 monte sur la rampe R1, il pivote dans le sens horaire et déplace l'équipage mobile 32 angulairement dans le sens anti-horaire. Au moment où la levée 52 tombe dans l'encoche E1, le palpeur 30 pivote autour de son axe 64 dans le sens anti-horaire et déplace l'équipage mobile 32 angulairement dans le sens horaire, ce qui fait effectuer au disque 2 le pas de rattrapage requis. Le bec 84 du cliquet 34 qui est immobilisé par la came inertielle, pousse alors la denture 22 dans le sens horaire. Simultanément, le mouvement de rotation du palpeur 30 provoque la rotation de la roue 72, par traction sur le levier 68. La roue 72 étant solidaire du pignon 44, le mouvement de traction du levier 68 provoque également la rotation de la came 26 du même pas de rattrapage, de sorte que cette came 26 reste en phase avec les périodes, des mois suivants.To comment further on the above, we will specify that during the successive days of the months to 31 days, the lift 52 rises gradually along one of the ramps R1 to R5 of the cam 26. During this journey which represents, in the case of the ramp R1, the interval between two months, the spring 50 was gradually bandaged by the arm 62 of feeler 30 and armed the feeler 30 so that it falls into the notch E1, when the finger 40 will have ordered the displacement of the cam 26. When the probe 30 progresses along the ramp R1, it pivots about its axis 64 and leads to an angular displacement of the moving assembly 32, via the pin 60. When the feeler 30 goes up on ramp R1, it pivots in the direction time and moves the mobile equipment 32 angularly in counter clockwise. At the moment the lifting 52 falls into the notch E1, the probe 30 pivots about its axis 64 counter-clockwise and moves the moving equipment 32 angularly clockwise, which causes to disk 2 the catch-up required. The bill 84 of the ratchet 34 which is immobilized by the inertial cam, then push the toothing 22 clockwise. Simultaneously, the rotation movement of the probe 30 causes rotation of the wheel 72, by pulling on the lever 68. The wheel 72 being integral with the pinion 44, the pulling movement of the lever 68 also causes the rotation of the cam 26 of the same retrofit step, so that this cam 26 remains in phase with the periods, following months.

La figure 9 montre la situation du mouvement après le pas de rattrapage, au passage du 31 au 1er, à la fin d'un mois de 30 jours.Figure 9 shows the situation of the movement after the catch-up, from the 31st to the 1st , at the end of a 30-day month.

Lors du pas, c'est-à-dire au moment où le palpeur est tombé dans l'encoche E1, le levier articulé 68 par l'entraínement de son bec 70 a fait tourner le mobile des roues.42, 72 et 44 d'un pas. Ainsi, la levée 52 n'est pas tombée directement au fond de l'encoche E1, mais à une distance de la paroi verticale de l'encoche E1, cette distance correspondant à un jour pour une fin de mois à 30 jours. During the step, that is to say when the probe is dropped into the notch E1, the articulated lever 68 by the drive of its beak 70 has rotated the mobile of wheels.42, 72 and 44 a step. So the lift 52 is not fallen directly to the bottom of the notch E1, but at a distance from the vertical wall of the notch E1, this distance corresponding to one day for a month end to 30 days.

Les figures 10 et 11 montrent la situation du mouvement avant et après les trois pas de rattrapage, pour le passage du 29 au 1er, à la fin d'un mois de 28 jours.Figures 10 and 11 show the situation of the movement before and after the three steps of catching, for the passage of the 29 to the 1 st , at the end of a month of 28 days.

Le mécanisme du mouvement selon l'invention fonctionne d'une façon identique à ce qui a été décrit précédemment à la différence que le nombre de pas est déterminé par la profondeur de l'encoche E3. Cette encoche a une profondeur a priori prévue pour que le déplacement du palpeur 30 dans cette encoche provoque un déplacement du disque 2 de trois pas, grâce à un déplacement angulaire correspondant de l'équipage mobile.The mechanism of the movement according to the invention works in the same way as described previously with the difference that the number of steps is determined by the depth of the notch E3. This notch has a priori expected depth so that the displacement of the probe 30 in this notch causes a displacement of the disc 2 of three steps, thanks to an angular displacement correspondent of the mobile crew.

Cependant, à la fin du mois de février des années bissextiles (voir figures 14 et 15), l'encoche E3 peut être partiellement obstruée pour ne provoquer qu'un déplacement du disque 2 de deux pas et un jour plus tard. L'obstruction de cette encoche E3 est effectuée en temps et en heure à l'aide du mécanisme 100 décrit ci-dessus, et notamment via le volet 102.However, at the end of February years leap (see Figures 14 and 15), the E3 notch may be partially obstructed to cause only one moving the disc 2 two steps and a day later. The obstruction of this notch E3 is performed in time and hour using the mechanism 100 described above, and in particular via section 102.
