Description

Domaine de l'inventionField of the invention

L'invention concerne un mouvement d'horlogerie comportant au moins un organe régulateur qui est un tourbillon ou carrousel comportant une cage, ledit mouvement comportant un mécanisme d'entraînement comportant une structure fixe sur laquelle est monté pivotant, autour d'un axe principal, un bras porteur de ladite cage, ledit bras étant soumis au couple de rappel d'une première source d'énergie, ledit mécanisme d'entraînement comportant encore au moins une deuxième source d'énergie, agencée pour réalimenter en permanence ladite première source d'énergie.The invention relates to a timepiece movement comprising at least one regulating member which is a tourbillon or carousel comprising a cage, said movement comprising a drive mechanism comprising a fixed structure on which is pivotally mounted, around a main axis, an arm carrying said cage, said arm being subjected to the return torque of a first energy source, said drive mechanism further comprising at least a second energy source, arranged to permanently replenish said first source of energy energy.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant un tel mouvement.The invention also relates to a timepiece, in particular a watch, comprising such a movement.

L'invention concerne le domaine des mécanismes d'entraînement d'horlogerie, et le domaine des mécanismes d'affichage d'horlogerie.The invention relates to the field of clockwork drive mechanisms, and the field of clockwork display mechanisms.

Arrière-plan de l'inventionInvention background

Les amateurs de complications horlogères sont sensibles à une certaine animation des affichages d'une pièce d'horlogerie, ce que peuvent procurer des mécanismes d'affichage rétrograde, ou encore des mécanismes de tourbillon ou similaire, qui de surcroît garantissent une meilleure insensibilité aux positions.Lovers of horological complications are sensitive to a certain animation of the displays of a timepiece, which can be achieved by retrograde display mechanisms, or by tourbillon mechanisms or the like, which in addition guarantee better insensitivity to the positions. .

Un éclatement des affichages est également apprécié, et permet d'offrir une nouvelle physionomie du cadran ou du mécanisme.A bursting of the displays is also appreciated, and makes it possible to offer a new physiognomy of the dial or the mechanism.

Les affichages rétrogrades sont généralement limités à l'entraînement d'aiguilles, ou plus rarement de disques.Retrograde displays are generally limited to driving needles, or more rarely discs.

L'entraînement rétrograde d'une cage de tourbillon ou de carrousel n'a jamais pu être réalisé, car une cage ne peut revenir en arrière sur sa roue fixe, et doit tourner toujours dans le même sens. Si l'on introduit un système de débrayage, par came ou similaire, pour ramener la cage en arrière, la marche cesse durant le mouvement rétrograde, ce qui n'est pas admissible.The retrograde drive of a tourbillon or carousel cage has never been possible, because a cage cannot go back on its fixed wheel, and must always rotate in the same direction. If a clutch release system, by cam or similar, is introduced to bring the cage back, walking stops during the retrograde movement, which is not admissible.

Le document CH709331A2 au nom de SEIKO INSTR. décrit un mécanisme d'affichage qui comprend une unité de cage comprenant un échappement et un régulateur, et une unité de fonctionnement configurée pour différencier la vitesse de déplacement de l'unité de cage avec le passage du temps et pour déplacer l'unité de cage dans la direction se rapprochant de ou s'éloignant d'un premier axe qui est le centre d'une zone d'affichage particulier, dans lequel l'unité de fonctionnement déplace l'unité de cage de manière que la trajectoire de mouvement, reproduite lorsque l'unité de cage se déplace dans la direction se rapprochant du premier axe qui est le centre de la zone d'affichage particulier, est en continuité avec la trajectoire de mouvement reproduite lorsque l'unité de cage se déplace dans la direction s'éloignant du premier axe qui est le centre de la zone d'affichage particulier.The document CH709331A2 on behalf of SEIKO INSTR. describes a display mechanism which comprises a cage unit comprising an exhaust and a regulator, and an operating unit configured to differentiate the speed of movement of the cage unit with the passage of time and to move the cage unit in the direction approaching or moving away from a first axis which is the center of a particular display area, in which the operating unit moves the cage unit so that the movement path, reproduced when the cage unit moves in the direction approaching the first axis which is the center of the particular display area, is continuous with the path of movement reproduced when the cage unit moves in the direction away from the first axis which is the center of the particular display area.

Résumé de l'inventionSummary of the invention

L'invention se propose de développer un mécanisme d'entraînement rétrograde qui soit capable d'embarquer des mobiles d'inertie beaucoup plus importante que des aiguilles, notamment des tourbillons ou similaires, et de ce fait de proposer des affichages entièrement nouveaux.The invention proposes to develop a retrograde drive mechanism which is capable of carrying mobiles of much greater inertia than needles, in particular vortices or the like, and therefore of proposing entirely new displays.

A cet effet, l'invention concerne un mouvement d'horlogerie selon la revendication 1.To this end, the invention relates to a timepiece movement according to claim 1.

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

Description détaillée des modes de réalisation préférésDetailed description of preferred embodiments

L'invention concerne un mouvement d'horlogerie 500 comportant au moins un organe régulateur 15 qui est un tourbillon ou un carrousel comportant une cage 150, et comportant un mécanisme d'entraînement 100 d'horlogerie, qui présente l'intérêt de pouvoir être utilisé dans une montre, ou encore dans une pièce d'horlogerie statique, avec des fonctionnalités nouvelles.The invention relates to a clockwork movement 500 comprising at least one regulating member 15 which is a tourbillon or a carousel comprising a cage 150, and comprising a clockwork drive mechanism 100, which has the advantage of being able to be used in a watch, or in a static timepiece, with new features.

Ce mécanisme d'entraînement 100 comporte une structure 110, telle que platine, pont ou similaire, sur laquelle est monté un bras 1 pivotant autour d'un axe principal D0. Ce bras 1 est porteur d'un premier mécanisme, qui constitue un satellite 10, lequel est monté pivotant sur le bras 1 autour d'un premier axe de pivotement D1, qui est distant de l'axe principal D0. Ce satellite 10 comporte une première roue 11, qui est montée pivotante autour du premier axe de pivotement D1 ou d'un axe de pivotement secondaire D11 qui lui est parallèle.This drive mechanism 100 comprises a structure 110, such as a plate, bridge or the like, on which is mounted an arm 1 pivoting about a main axis D0. This arm 1 carries a first mechanism, which constitutes a satellite 10, which is pivotally mounted on the arm 1 around a first pivot axis D1, which is distant from the main axis D0. This satellite 10 comprises a first wheel 11, which is pivotally mounted around the first pivot axis D1 or a secondary pivot axis D11 which is parallel to it.

Le bras 1 est soumis au couple de rappel d'une première source d'énergie 12, telle qu'un barillet, un système de poids, ou autre.The arm 1 is subjected to the return torque of a first energy source 12, such as a barrel, a weight system, or the like.

Le mécanisme d'entraînement 100 comporte encore au moins une deuxième source d'énergie 22, qui est agencée pour soumettre à un couple de rappel un troisième mobile 3 que comporte le mécanisme d'entraînement 100, directement ou indirectement au travers d'un deuxième mobile 2 monté pivotant autour d'un deuxième axe de pivotement D2, comme dans la variante particulière et non limitative illustrée par les figures 1 et 2.The drive mechanism 100 also comprises at least a second energy source 22, which is arranged to subject a third mobile 3 to a restoring torque 3 which the drive mechanism 100 includes, directly or indirectly through a second mobile 2 mounted pivoting around a second pivot axis D2, as in the particular and non-limiting variant illustrated by the figures 1 and 2 .

Cette deuxième source d'énergie 22 est la source d'énergie principale, et elle est agencée pour stocker davantage d'énergie que la première source d'énergie 12.This second energy source 22 is the main energy source, and it is arranged to store more energy than the first energy source 12.

La première roue 11 est agencée pour rouler sur le troisième mobile 3 dans un mouvement de roulement d'avance régulier, sous l'action du couple de rappel de la première source d'énergie 12.The first wheel 11 is arranged to roll on the third mobile 3 in a regular advance rolling movement, under the action of the restoring torque of the first energy source 12.

Le satellite 10 constitue, ainsi, un mobile planétaire, qui se déplace en rotation autour du troisième mobile 3, autour de l'axe principal D0, toujours dans le même sens, selon la flèche G (sens horaire sur la figure 1), et à vitesse constante.The satellite 10 thus constitutes a planetary mobile, which rotates around the third mobile 3, around the main axis D0, always in the same direction, according to the arrow G (clockwise on the figure 1 ), and at constant speed.

De façon propre à l'invention, le troisième mobile 3 est agencé pour rester en position fixe pendant une première course élémentaire du satellite 10, et pour effectuer une rotation, et de façon particulière une rotation rapide, toujours dans un seul sens, celui de la flèche B anti-horaire sur les figures 1 et 2, pendant une deuxième course élémentaire de la course du satellite 10, sous l'action de la deuxième source d'énergie 22.Specifically to the invention, the third mobile 3 is arranged to remain in a fixed position during a first elementary stroke of the satellite 10, and to perform a rotation, and in particular a rapid rotation, always in one direction, that of the anti-clockwise arrow B on the figures 1 and 2 , during a second elementary race of the race of the satellite 10, under the action of the second energy source 22.

Et la première roue 11 entraîne la cage 150 du tourbillon ou carrousel, ou constitue la cage 150 du tourbillon ou carrousel.And the first wheel 11 drives the cage 150 of the tourbillon or carousel, or constitutes the cage 150 of the tourbillon or carousel.

Ainsi, par rapport à la structure fixe 110, le bras 1 se déplace dans le sens de la flèche E sous l'action de la première source d'énergie 12 relativement au troisième mobile 3 quand celui-ci est à l'arrêt, tandis que, lors du rappel du troisième mobile 3 sous l'action de la deuxième source d'énergie 22, le bras 1, qui est porté par le troisième mobile 3, se déplace de façon rétrograde dans le sens de la flèche F, par rapport à la structure fixe 110, pendant la deuxième course élémentaire du satellite 10.Thus, with respect to the fixed structure 110, the arm 1 moves in the direction of the arrow E under the action of the first energy source 12 relative to the third mobile 3 when the latter is stopped, while that, when the third mobile 3 is recalled under the action of the second energy source 22, the arm 1, which is carried by the third mobile 3, moves retrograde in the direction of the arrow F, with respect to to the fixed structure 110, during the second elementary race of the satellite 10.

On comprend que le satellite 10 roule en permanence autour du troisième mobile 3, et qu'il continue à tourner par rapport au troisième mobile 3 pendant la rotation de ce dernier. Il y a donc une alternance de premières courses élémentaires et de deuxièmes courses élémentaires.It is understood that the satellite 10 rolls continuously around the third mobile 3, and that it continues to rotate relative to the third mobile 3 during the rotation of the latter. There is therefore an alternation of first elementary races and second elementary races.

Du fait des rotations successives du bras dans le premier sens d'avance selon la flèche E, et selon le deuxième sens réverse selon la flèche F, l'axe D1 effectue une course angulaire limitée autour de l'axe principal D0.Due to the successive rotations of the arm in the first direction of advance along the arrow E, and in the second reverse direction along the arrow F, the axis D1 performs a limited angular travel around the main axis D0.

De façon particulière et non limitative, la première course élémentaire du satellite 10, est très supérieure à la deuxième course élémentaire de la course, notamment plus de vingt fois supérieure à celle-ci.In a particular and nonlimiting manner, the first elementary race of the satellite 10 is much greater than the second elementary race of the race, in particular more than twenty times greater than the latter.

Dans l'exemple avantageux illustré par les figures 1 et 2, le cycle complet dure une minute, avec cinquante-huit secondes de parcours à vitesse lente du bras 1 dans la première course élémentaire, et deux secondes de retour rapide du bras 1 dans la deuxième course élémentaire.In the advantageous example illustrated by figures 1 and 2 , the complete cycle lasts one minute, with fifty-eight seconds of slow speed travel of arm 1 in the first elementary race, and two seconds of rapid return of arm 1 in the second elementary race.

L'invention permet toutefois de moduler autrement le rapport entre la première partie de course et la deuxième course élémentaire de course, il est par exemple imaginable d'obtenir une première course élémentaire et une deuxième course élémentaire égales.The invention however makes it possible to otherwise modulate the ratio between the first part of the race and the second elementary race of the race, it is for example imaginable to obtain a first elementary race and a second elementary race equal.

Dans la variante illustrée par les figures 1 et 2, pour gérer le mouvement de rotation du troisième mobile 3, le mécanisme d'entraînement 100 comporte des moyens d'arrêt 120, qui sont fixés sur la structure 110, et qui sont plus particulièrement agencés pour coopérer avec des moyens d'arrêt complémentaire 123 que comporte le troisième mobile 3 pour son maintien en position, ou que comporte un autre mobile extérieur engrenant directement ou indirectement avec le troisième mobile 3. Les moyens d'arrêt 120 comportent plus particulièrement un levier déclencheur, qui est agencé pour coopérer successivement avec des goupilles réparties sur le troisième mobile 3, et qui constituent ces moyens d'arrêt complémentaire 123 dans l'exemple non limitatif illustré par les figures 1 et 2. Dans l'exemple illustré ces goupilles sont disposées angulairement de façon régulière. Il est néanmoins possible de concevoir d'autres espacements angulaires, pour réaliser des affichages particuliers.In the variant illustrated by figures 1 and 2 , to manage the rotational movement of the third mobile 3, the drive mechanism 100 includes stop means 120, which are fixed to the structure 110, and which are more particularly arranged to cooperate with complementary stop means 123 that includes the third mobile 3 for maintaining it in position, or that includes another external mobile engaging directly or indirectly with the third mobile 3. The stop means 120 more particularly comprise a trigger lever, which is arranged to cooperate successively with pins distributed on the third mobile 3, and which constitute these complementary stop means 123 in the nonlimiting example illustrated by the figures 1 and 2 . In the example illustrated, these pins are arranged angularly in a regular manner. It is nevertheless possible to design other angular spacings, to produce particular displays.

Ces moyens d'arrêt 120 sont débrayables, sous l'action de moyens de commande de débrayage 13 que comporte le bras 1, quand la première roue 11 termine sa première course élémentaire, pour autoriser le pivotement du troisième mobile 3 dans un sens unique (flèche B anti-horaire) sous l'action de la deuxième source d'énergie 22 en entraînant une rotation rétrograde du bras 1 jusqu'au début de sa course angulaire.These stop means 120 are disengageable, under the action of declutching control means 13 that comprises the arm 1, when the first wheel 11 ends its first elementary stroke, to allow the pivoting of the third mobile 3 in a single direction ( anti-clockwise arrow B) under the action of the second energy source 22 by causing a retrograde rotation of the arm 1 until the start of its angular travel.

Quand le troisième mobile 3 est à l'arrêt dans une position angulaire de butée, la première roue 11 effectue une première course élémentaire, et le bras 1 se déplace en course angulaire d'avance à une vitesse lente qui est sa vitesse d'affichage. A la fin de cette première course élémentaire de la première roue 11, les moyens de commande de débrayage 13 débrayent les moyens d'arrêt 120, et le troisième mobile 3 est alors libre et soumis au couple de la deuxième source d'énergie 22, directement ou au travers du deuxième mobile 2 selon la variante de construction retenue. Le troisième mobile 3 effectue alors une rotation, et plus particulièrement une rotation brusque et quasiment instantanée, avant de revenir à une autre position angulaire de butée entre une autre goupille 123 et le levier déclencheur 120. Et cette rotation du troisième mobile 3 entraîne le retour rétrograde du bras 1 à sa position de début de course angulaire, et notamment dans le cas illustré à une vitesse accélérée qui est très supérieure à sa vitesse lente d'affichage.When the third mobile 3 is stopped in an angular stop position, the first wheel 11 performs a first elementary stroke, and the arm 1 moves in angular stroke in advance at a slow speed which is its display speed . At the end of this first elementary stroke of the first wheel 11, the declutching control means 13 disengage the stop means 120, and the third mobile 3 is then free and subjected to the torque of the second energy source 22, directly or through the second mobile 2 depending on the construction variant selected . The third mobile 3 then performs a rotation, and more particularly a sudden and almost instantaneous rotation, before returning to another angular abutment position between another pin 123 and the trigger lever 120. And this rotation of the third mobile 3 causes the return retrograde of the arm 1 to its angular start position, and in particular in the case illustrated at an accelerated speed which is much higher than its slow display speed.

Dans une autre variante, la première roue 11 est agencée pour rouler à l'intérieur du troisième mobile 3. Bien d'autres configurations sont envisageables, notamment concernant les positions relatives des différents axes de pivotement, avec des cascades de renvois adaptées.In another variant, the first wheel 11 is arranged to roll inside the third mobile 3. Many other configurations are possible, in particular concerning the relative positions of the different pivot axes, with cascades of suitable references.

Naturellement il est encore possible de soumettre le troisième mobile 3 au couple d'au moins une troisième source d'énergie, par exemple en engrènement direct.Naturally, it is also possible to subject the third mobile 3 to the torque of at least one third energy source, for example in direct engagement.

Le fonctionnement du mécanisme d'entraînement 100 est tributaire du niveau d'énergie disponible au niveau de la deuxième source d'énergie 22. Dans le cas où le mécanisme d'entraînement 100 est intégré dans une montre, la deuxième source d'énergie 22 est avantageusement rechargée par un mécanisme de remontage automatique, non détaillé ici car bien connu de l'homme du métier : la première source d'énergie 11 est en permanence réarmée par la deuxième source d'énergie tant que celle-ci dispose de suffisamment d'énergie, cette première source d'énergie 11 constitue ainsi un tampon, et l'entraînement du satellite 10 par cette première source d'énergie 11 est ainsi un mécanisme dit à force constante, ou plus précisément à couple constant, jusqu'à la fin de la réserve de marche du barillet principalThe operation of the drive mechanism 100 is dependent on the level of energy available at the second energy source 22. In the case where the drive mechanism 100 is integrated in a watch, the second energy source 22 is advantageously recharged by an automatic winding mechanism, not detailed here as well known to those skilled in the art: the first energy source 11 is permanently reset by the second energy source as long as the latter has sufficient energy, this first energy source 11 thus constitutes a buffer, and the drive of satellite 10 by this first energy source 11 is thus a mechanism known as constant force, or more precisely constant torque, until the end of the main barrel power reserve

Dans la variante très compacte illustrée par les figures 1 et 2, les moyens d'arrêt 120 comportent une bascule, qui forme un levier déclencheur, et qui est montée pivotante sur un axe de bascule D12, et qui est rappelée dans le sens de la flèche D par des moyens de rappel élastique 127, tels que ressort ou similaire. Cette bascule porte une goupille de bascule 129.In the very compact variant illustrated by figures 1 and 2 , the stop means 120 comprise a rocker, which forms a trigger lever, and which is pivotally mounted on a rocker axis D12, and which is returned in the direction of the arrow D by elastic return means 127, such as spring or similar. This rocker carries a rocker pin 129.

Le bras 1 comporte une rampe 13, qui est agencée pour coopérer avec la goupille de bascule 129, en fin de course angulaire d'avance du bras 1, et pour repousser la bascule dans le sens de la flèche C, ce qui permet d'éclipser un bec de la bascule comportant une surface d'appui 128, qui jusque-là maintenait en position une goupille de butée 123, que comporte le troisième mobile 3 (qui en comporte trois à 120° dans le cas d'espèce). Le troisième mobile 3 est alors libéré, et peut tourner, sa goupille 123 précédemment immobilisée pouvant passer sous le bras 1. La position des goupilles 123 dirige le déclenchement, elles sont garantes de la précision de la durée d'une période de course totale.The arm 1 comprises a ramp 13, which is arranged to cooperate with the rocker pin 129, at the end of the angular advance travel of the arm 1, and for push the rocker in the direction of arrow C, which makes it possible to eclipse a beak of the rocker comprising a bearing surface 128, which until then maintained in position a stop pin 123, which comprises the third mobile 3 ( which includes three at 120 ° in the present case). The third mobile 3 is then released, and can rotate, its pin 123 previously immobilized being able to pass under the arm 1. The position of the pins 123 directs the triggering, they guarantee the precision of the duration of a period of total travel.

De façon avantageuse, le bras 1 comporte des moyens de limitation 20, qui tendent à s'opposer au couple moteur de la première source d'énergie 12, et qui sont agencés pour limiter la vitesse de roulement de la première roue 11. En effet, tout ce qui peut ralentir le système est avantageux, pour un fonctionnement régulier du mécanisme à force constante que constitue l'invention.Advantageously, the arm 1 comprises limiting means 20, which tend to oppose the driving torque of the first energy source 12, and which are arranged to limit the running speed of the first wheel 11. Indeed , anything that can slow down the system is advantageous for regular operation of the constant force mechanism that constitutes the invention.

Plus particulièrement, ces moyens de limitation 20 sont des moyens de freinage et/ou de friction et/ou de régulation. Ils peuvent notamment comporter des moyens de freinage aérodynamique, par courants de Foucault, ou autre. Par exemple, la première roue 11 peut porter une aiguille des secondes.More particularly, these limiting means 20 are braking and / or friction and / or regulation means. They may in particular include aerodynamic braking means, by eddy currents, or the like. For example, the first wheel 11 can carry a second hand.

Plus particulièrement encore, comme dans le cas non limitatif illustré par les figures 1 et 2, les moyens de limitation 20 sont des moyens de régulation de la vitesse de roulement de la première roue 11 autour du troisième mobile 3. Le mécanisme régulateur est de préférence au niveau du satellite 10 qui constitue un mobile planétaire.More particularly still, as in the nonlimiting case illustrated by the figures 1 and 2 , the limiting means 20 are means for regulating the running speed of the first wheel 11 around the third mobile 3. The regulating mechanism is preferably at the level of the satellite 10 which constitutes a planetary mobile.

Tel que visible dans une variante non limitative illustrée par les figures 1 et 2, les moyens de régulation de la vitesse de roulement de la première roue 11 autour du troisième mobile 3 comportent un arrêtoir 17, tel qu'une ancre ou similaire, et qui est agencé pour coopérer de façon discontinue avec la première roue 11, ou avec un mobile synchrone de la première roue 11, ou avec un quatrième mobile engrenant directement ou indirectement avec la première roue 11.As visible in a nonlimiting variant illustrated by the figures 1 and 2 , the means for regulating the running speed of the first wheel 11 around the third mobile 3 comprise a retainer 17, such as an anchor or the like, and which is arranged to cooperate discontinuously with the first wheel 11, or with a synchronous mobile of the first wheel 11, or with a fourth mobile engaging directly or indirectly with the first wheel 11.

De façon particulière et tel que visible sur les figures 1 et 2, le deuxième axe de pivotement D2 est parallèle à l'axe principal D0 et distinct de lui.In a particular way and as visible on the figures 1 and 2 , the second pivot axis D2 is parallel to the main axis D0 and distinct from it.

De façon particulière et tel que visible sur les figures 1 et 2, le troisième mobile 3 est agencé pour pivoter autour de l'axe principal D0.In a particular way and as visible on the figures 1 and 2 , the third mobile 3 is arranged to pivot around the main axis D0.

Tout particulièrement, le satellite 10 constitue tout ou partie des moyens de limitation 20, et est un organe régulateur 15.In particular, the satellite 10 constitutes all or part of the limiting means 20, and is a regulating member 15.

Plus particulièrement, l'organe régulateur 15 comporte au moins une masse inertielle 1700 soumise à un mouvement de pivotement alternatif par une ancre 170, que comporte l'arrêtoir 17, et qui est agencée pour coopérer avec un rochet 18 entraîné directement ou indirectement par la première roue 11. Cette ancre 170 permet de limiter la vitesse pour éviter l'emballement, notamment lors du retour rapide en 2 secondes.More particularly, the regulating member 15 comprises at least one inertial mass 1700 subjected to an alternating pivoting movement by an anchor 170, which comprises the retainer 17, and which is arranged to cooperate with a ratchet 18 driven directly or indirectly by the first wheel 11. This anchor 170 makes it possible to limit the speed to avoid runaway, in particular during the rapid return in 2 seconds.

Plus particulièrement, le rochet 18 est coaxial à la première roue 11.More particularly, the ratchet 18 is coaxial with the first wheel 11.

Plus particulièrement ce rochet 18 est une roue d'échappement.More particularly, this ratchet 18 is an escape wheel.

Quand l'organe régulateur 15.est un tourbillon, la première roue 11 entraîne la cage 150 du tourbillon, ou bien constitue la cage 150 du tourbillon. Dans ce cas, l'axe du mécanisme résonateur, typiquement un balancier-spiral, que comporte l'organe régulateur 15, est confondu avec le premier axe de pivotement D1.When the regulating member 15.is a vortex, the first wheel 11 drives the cage 150 of the vortex, or else constitutes the cage 150 of the vortex. In this case, the axis of the resonator mechanism, typically a balance-spring, which comprises the regulating member 15, coincides with the first pivot axis D1.

Quand l'organe régulateur 15 est un carrousel, la première roue 11 entraîne la cage du carrousel ou constitue la cage du carrousel. Dans ce cas, l'axe du mécanisme résonateur, typiquement un balancier-spiral, que comporte l'organe régulateur 15, est un axe de pivotement secondaire, parallèle au premier axe de pivotement D1, par exemple situé à l'extrémité distale d'un régulateur 19 tel qu'illustré sur les figures 1 et 2.When the regulating member 15 is a carousel, the first wheel 11 drives the carousel cage or constitutes the carousel cage. In this case, the axis of the resonator mechanism, typically a balance-spring, which comprises the regulating member 15, is a secondary pivot axis, parallel to the first pivot axis D1, for example located at the distal end of a regulator 19 as illustrated on the figures 1 and 2 .

Plus particulièrement, l'organe régulateur 15 comporte un régulateur 19, qui est entraîné directement ou indirectement par la première roue 1.More particularly, the regulating member 15 comprises a regulator 19, which is driven directly or indirectly by the first wheel 1.

Plus particulièrement, ce régulateur 19 est synchrone avec la première roue 11, et est apte à constituer un premier afficheur d'une première grandeur temporelle.More particularly, this regulator 19 is synchronous with the first wheel 11, and is capable of constituting a first display of a first time quantity.

Plus particulièrement encore, le régulateur 19 est une cage de tourbillon ou de carrousel.More particularly still, the regulator 19 is a tourbillon or carousel cage.

Chaque mobile du mécanisme d'entraînement du mouvement selon l'invention est utilisable pour un affichage particulier. Ainsi, plus particulièrement, le bras 1 constitue ou entraîne un afficheur d'une deuxième grandeur temporelle. Ce bras peut porter des affichages excentrés, par exemple sur des étoiles montées pivotantes sur le bras 1.Each mobile of the movement drive mechanism according to the invention can be used for a particular display. Thus, more particularly, the arm 1 constitutes or drives a display of a second temporal magnitude. This arm can carry eccentric displays, for example on stars pivotally mounted on the arm 1.

De façon similaire, plus particulièrement, le troisième mobile 3 constitue ou entraîne un afficheur d'une troisième grandeur temporelle, par exemple un afficheur des minutes avançant par sauts.Similarly, more particularly, the third mobile 3 constitutes or drives a display of a third temporal magnitude, for example a display of the minutes advancing by jumps.

Plus particulièrement, le deuxième mobile 2 constitue ou entraîne un afficheur de réserve de marche.More particularly, the second mobile 2 constitutes or drives a power reserve display.

On comprend que ce mécanisme d'entraînement propre à l'invention autorise un affichage très vivant de l'écoulement du temps, par le roulement très visible de la première roue 11 sur le troisième mobile 3, et par le retour rétrograde périodique du bras 1. Chaque mobile est utilisable pour porter un affichage décentré.We understand that this drive mechanism specific to the invention allows a very lively display of the passage of time, by the very visible rolling of the first wheel 11 on the third mobile 3, and by the periodic retrograde return of the arm 1 Each mobile can be used to carry an off-center display.

L'invention concerne encore une pièce d'horlogerie 1000 comportant au moins un tel mouvement d'horlogerie 500, et qui dans une première variante est une montre. Sa première source d'énergie 12 et/ou sa deuxième source d'énergie 22 peut classiquement comporter au moins un barillet, et/ou une source d'énergie électromécanique, ou autre. Avantageusement la deuxième source d'énergie 22 est rechargée par un mécanisme de remontage automatique.The invention also relates to a timepiece 1000 comprising at least one such timepiece movement 500, and which in a first variant is a watch. Its first energy source 12 and / or its second energy source 22 can conventionally comprise at least one barrel, and / or an electromechanical, or other, energy source. Advantageously, the second energy source 22 is recharged by an automatic winding mechanism.

Dans une autre variante, la pièce d'horlogerie 1000 est statique, et peut être notamment une pendule. Sa première source d'énergie 12 et/ou sa deuxième source d'énergie 22 peut classiquement comporter au moins un barillet, et/ou une source d'énergie électromécanique, ou autre. Ou encore sa première source d'énergie 12 et/ou sa deuxième source d'énergie 22 comporte au moins un poids, et cette pièce d'horlogerie 1000 comporte alors des moyens de remontage de chaque poids. Toutefois de préférence la première source d'énergie 12 est un barillet faisant tampon, ce qui permet de ne devoir remonter que la deuxième source d'énergie 22 qui alimente la première source d'énergie 12.In another variant, the timepiece 1000 is static, and may in particular be a pendulum. Its first energy source 12 and / or its second energy source 22 can conventionally comprise at least one barrel, and / or an electromechanical, or other, energy source. Or its first energy source 12 and / or its second energy source 22 comprises at least one weight, and this timepiece 1000 then comprises means for winding each weight. Preferably, however, the first energy source 12 is a buffer barrel, which means that only the second energy source 22 which feeds the first energy source 12 has to be raised.

Le principe de l'invention est applicable à bien d'autres variantes, et à de nombreuses applications particulières. Ce principe est illustré, de façon simplifiée par rapport aux figures 1 et 2, par les figures 4 à 9, qui ne comportent que la première source d'énergie 12, illustrée sous la forme d'un simple ressort plat, le bras 1 porteur de la première roue 11, et le troisième mobile 3 sur lequel tourne cette première roue 11. Dans cet exemple, une cage de tourbillon, portée par la première roue 11, effectue un tour par minute, la première roue 11 se déplace sur le troisième mobile 3 pendant environ 18 secondes quand le troisième mobile 3 est encore en position fixe, et continue à rouler sur ce troisième mobile pendant les deux secondes que dure le retour rétrograde de 120° du troisième mobile 3 dans le sens anti-horaire sur ces figures. La figure 5 montre l'ensemble en position juste après un tel retour rétrograde ; la figure 6 montre une position intermédiaire X ; la figure 7 montre la position angulaire extrême du bras 1 en course horaire, et la figure 8 illustre le retour rétrograde en sens anti-horaire du troisième mobile (visible par le changement de position des repères 1, 2, 3) et du bras 1 qu'il porte.The principle of the invention is applicable to many other variants, and to many particular applications. This principle is illustrated, in a simplified manner compared to figures 1 and 2 , by figures 4 to 9 , which comprise only the first energy source 12, illustrated in the form of a simple flat spring, the arm 1 carrying the first wheel 11, and the third mobile 3 on which this first wheel turns 11. In this example , a tourbillon carriage, carried by the first wheel 11, makes one revolution per minute, the first wheel 11 moves on the third mobile 3 for approximately 18 seconds when the third mobile 3 is still in the fixed position, and continues to roll on this third mobile during the two seconds that the retrograde return of 120 ° lasts from the third mobile 3 counterclockwise in these figures. The figure 5 shows the assembly in position just after such a retrograde return; the figure 6 shows an intermediate position X; the figure 7 shows the extreme angular position of arm 1 in time travel, and the figure 8 illustrates the retrograde counterclockwise return of the third mobile (visible by the change in position of the pins 1, 2, 3) and of the arm 1 which it carries.

La figure 10 illustre encore une autre variante, avec un bras 1 faisant râteau d'armage sur un barillet d'armage du bras de cage, constituant la première source d'énergie 12, qui mène le bras 1 de cage; sous l'effet de son couple, la cage de tourbillon est menée et fait sa rotation sur la circonférence du troisième mobile 3, le bras 1 se déplace en fonction de la fréquence et du rapport d'engrenage. Le bras 1 menant la cage se déplace de sa position première de 0° et arrive à sa position maximale 120°. Il se produit à cet instant un déverrouillage de la deuxième source d'énergie 22, ici constituée par le barillet du mouvement de base d'une montre. Ce barillet est en chaîne avec un mobile de réduction 2230, et celui-ci en liaison avec le troisième mobile 3. La force du barillet mouvement 22 va mener le mobile de réduction 2230 et de fait va mener le troisième mobile 3 en rotation anti-horaire de 120°. Le déplacement en degrés du troisième mobile 3 est géré via un train de rouage 221 et positionné par une goupille d'arrêt au niveau d'un verrou de position 223, ce rouage 221 peut être en lien soit avec le mobile de réduction 2230, soit avec le barillet mouvement 22. Pour gérer le retour sur une durée d'environ de 2 secondes, un régulateur avec inverseur, comportant notamment un pignon, un rochet 18, une ancre 170, est en série avec le troisième mobile 3, et permet d'ajuster la durée du retour rétrograde, notamment comprise entre 1 et 10 secondes. Lors du déplacement de 120° du troisième mobile 3, la première source d'énergie 12, ici le ressort du bras de cage, se réarme, la cage continue à fonctionner en se déplaçant sur la circonférence du troisième mobile 3. Cette variante de la figure 10 permet de gérer la course angulaire autrement que par les goupilles 123 de la variante des figures 1 et 2, que remplace ici le rouage de position 221 il est ici possible de gérer d'autres valeurs angulaire, par exemple 360° pour afficher un passage de date, ou autre.The figure 10 illustrates yet another variant, with an arm 1 forming a winding rake on a winding barrel of the cage arm, constituting the first energy source 12, which leads the arm 1 of the cage; under the effect of its torque, the tourbillon cage is driven and rotated around the circumference of the third mobile 3, the arm 1 moves as a function of the frequency and of the gear ratio. The arm 1 leading the cage moves from its initial position by 0 ° and arrives at its maximum position 120 °. At this instant, the second energy source 22 is unlocked, here constituted by the barrel of the basic movement of a watch. This barrel is in chain with a reduction mobile 2230, and the latter in connection with the third mobile 3. The force of the movement barrel 22 will drive the reduction mobile 2230 and in fact will lead the third mobile 3 in anti-rotation 120 ° hourly. The displacement in degrees of the third mobile 3 is managed via a gear train 221 and positioned by a stop pin at the level of a position lock 223, this train 221 can be linked either to the reduction mobile 2230, or with the movement barrel 22. To manage the return over a period of approximately 2 seconds, a regulator with inverter, comprising in particular a pinion, a ratchet 18, an anchor 170, is in series with the third mobile 3, and allows d '' adjust the duration of the retrograde return, in particular between 1 and 10 seconds. During the 120 ° movement of the third mobile 3, the first energy source 12, here the spring of the cage arm, rearms, the cage continues to operate by moving around the circumference of the third mobile 3. This variant of the figure 10 used to manage the angular stroke other than by pins 123 of the variant of figures 1 and 2 , which is replaced here by the gear train 221, it is here possible to manage other angular values, for example 360 ° to display a passage of date, or the like.

On remarque que le ressort de barillet de mouvement de base n'intercède plus avec le rouage de finissage comme sur un mouvement classique. Il a maintenant pour fonction unique de donner l'impulsion nécessaire au positionnement du troisième mobile 3.It is noted that the basic movement barrel spring no longer intercedes with the gear train as in a conventional movement. It now has the unique function of providing the necessary impetus for positioning the third mobile 3.

La première source d'énergie 12, ici le ressort du bras de cage, a un préarmage donnant le couple nécessaire au fonctionnement du tourbillon, cette force restera constante. La course angulaire de 120° en rotation anti-horaire du troisième mobile 3 arme de manière régulière le ressort de bras de cage.The first energy source 12, here the spring of the cage arm, has a pre-arm giving the torque necessary for the operation of the tourbillon, this force will remain constant. The angular travel of 120 ° in counterclockwise rotation of the third mobile 3 regularly arms the cage arm spring.

De cette façon, il est concevable d'élaborer plusieurs types de déplacement de l'aiguille d'heure et des minutes, ainsi que des complications comme les indications de la lune, et/ou jour/nuit, et/ou de la réserve de marche, tel que visible sur les figures 11 à 13, en particulier, au retour de la cage et du troisième mobile, ou encore avec le rouage de position où il n'est plus nécessaire d'utiliser une chaussée, et où la mise à l'heure est unidirectionnelle; ou avec le rouage de position; avec le rouage de position et /ou le barillet mouvement la mise à l'heure est possible dans les deux directions.In this way, it is conceivable to develop several types of movement of the hour and minute hand, as well as complications such as the indications of the moon, and / or day / night, and / or the reserve of step, as visible on figures 11 to 13 , in particular, on the return from the cage and the third mobile, or even with the gear train in which it is no longer necessary to use a carriageway, and where the time setting is unidirectional; or with the gear train; with the gear train and / or the movement barrel setting the time is possible in both directions.

Le remontage se fait par la couronne 220, le barillet principal 22 n'intercédera plus avec le rouage de finissage comme dans la technique usuelle.The reassembly is done by the crown 220, the main barrel 22 will no longer intercede with the gear train as in the usual technique.

Cet agencement permet, encore, de faire la correction de la lune directement par la couronne, il n'est plus nécessaire d'intégrer un correcteur intégré à la carrure.This arrangement also makes it possible to make the correction of the moon directly by the crown, it is no longer necessary to integrate a corrector integrated into the middle.

On comprend que l'invention assure une force motrice quasi constante au mécanisme régulateur, notamment une cage de tourbillon ou de carrousel, durant toute la réserve de marche du barillet principal.It is understood that the invention provides an almost constant driving force to the regulating mechanism, in particular a tourbillon or carousel cage, throughout the power reserve of the main barrel.

Les figures 11 à 14 illustrent la large latitude offerte par l'invention pour le positionnement des différents affichages. Sur l'exemple illustré, la lecture des heures et des minutes se fait sur un cadran à 12h, celle de la réserve de marche sur un secteur avec aiguille rétrograde à 9h, celle de l'affichage de lune et/ou jour/nuit, ou encore coucher de soleil, ou autre, à 3h, tandis que le tourbillon a un déplacement sur 120°, et qu'il est possible d'orienter le déplacement de la cage sur 120° selon un mouvement sensiblement périphérique comme sur les figures 11 et 14, ou selon un mouvement autour d'un axe excentré au maximum comme sur les figures 12 et 13, avec un mouvement rétrograde de la cage respectivement de gauche à droite, ou de droite à gauche.The figures 11 to 14 illustrate the wide latitude offered by the invention for the positioning of the various displays. In the example illustrated, the hours and minutes are read on a dial at 12 o'clock, that of the power reserve on a sector with retrograde hand at 9 o'clock, that of the moon and / or day / night display, or even sunset, or other, at 3 o'clock, while the tourbillon has a movement over 120 °, and it is possible to orient the movement of the cage over 120 ° according to a substantially peripheral movement as on the Figures 11 and 14 , or according to a movement around a maximum eccentric axis as on the figures 12 and 13 , with a retrograde movement of the cage respectively from left to right, or from right to left.

La valeur de 120° prise pour les exemples n'est nullement contraignante, la valeur angulaire dépend de la durée de course horaire désirée, la valeur de la course rétrograde est elle aussi ajustable, par exemple entre 2 et 5 secondes, et permet d'obtenir un retour rétrograde non brusque, dépourvu de choc.The value of 120 ° taken for the examples is in no way binding, the angular value depends on the duration of the desired hourly stroke, the value of the retrograde stroke is also adjustable, for example between 2 and 5 seconds, and allows obtain an abrupt retrograde return, devoid of shock.

Le retour rétrograde de la cage permet d'alimenter le passage des minutes.The retrograde return of the cage feeds the passage of the minutes.

Le retour rétrograde n'est pas lié à la fréquence du mécanisme résonateur, et n'a aucune influence sur la marche du mouvement.The retrograde return is not linked to the frequency of the resonator mechanism, and has no influence on the movement.

Dans d'autres variantes d'exécution il est possible d'équiper le troisième mobile de plusieurs satellites 10 sur sa périphérie. Il est aussi possible de concevoir un système sur plusieurs étages pour gérer des fonctions distinctes.In other alternative embodiments it is possible to equip the third mobile with several satellites 10 on its periphery. It is also possible to design a multi-stage system to manage separate functions.

Les figures 15 à 31 illustrent, sur le principe de base de la figure 10, une exécution particulière de l'invention, dans laquelle la première roue 11 est une cage 150 de tourbillon, et où le troisième mobile 3 est un mobile de pas de cage 700, qui va être détaillé plus loin.The Figures 15 to 31 illustrate, on the basic principle of figure 10 , a particular embodiment of the invention, in which the first wheel 11 is a tourbillon cage 150, and where the third mobile 3 is a mobile with a cage pitch 700, which will be detailed below.

Selon l'invention, dans cette exécution, le mouvement d'horlogerie 500 comporte, pour la commande du mouvement rétrograde du bras pivotant rétrograde 1, un mécanisme très compact qui comporte un mobile déclencheur 600 relié cinématiquement à la deuxième source d'énergie 22, et qui est agencé pour coopérer avec un mobile de came 620 relié cinématiquement au bras 1 relié à la première source d'énergie 12.According to the invention, in this embodiment, the clockwork movement 500 comprises, for controlling the retrograde movement of the retrograde pivoting arm 1, a very compact mechanism which comprises a trigger mobile 600 kinematically connected to the second energy source 22, and which is arranged to cooperate with a cam mobile 620 kinematically connected to the arm 1 connected to the first energy source 12.

Ce mouvement d'horlogerie 500 comporte au moins un organe régulateur qui est un tourbillon ou carrousel comportant une cage 150. Le mouvement 500 comporte un mécanisme d'entraînement 100 comportant une structure fixe 110 sur laquelle est monté pivotant, autour d'un axe principal D0, un bras 1 porteur de la cage 150. Ce bras 1 est soumis au couple de rappel d'une première source d'énergie 12. Le mécanisme d'entraînement 100 comporte encore au moins une deuxième source d'énergie 22, agencée pour réalimenter en permanence la première source d'énergie 12.This clockwork movement 500 comprises at least one regulating member which is a tourbillon or carousel comprising a cage 150. The movement 500 comprises a drive mechanism 100 comprising a fixed structure 110 on which is pivotally mounted, around a main axis D0, an arm 1 carrying the cage 150. This arm 1 is subjected to the return torque of a first energy source 12. The drive mechanism 100 also comprises at least a second energy source 22, arranged for permanently replenish the first energy source 12.

Selon l'invention, la deuxième source d'énergie 22 est agencée pour entraîner un mobile de pas de cage 700, lequel entraîne lui-même un pignon de cage 710 pour l'entraînement en rotation de la cage 150.According to the invention, the second energy source 22 is arranged to drive a cage pitch mobile 700, which itself drives a cage pinion 710 for driving the cage 150 in rotation.

Et le mouvement 500 comporte, pour la commande périodique d'un mouvement rétrograde du bras 1, un mobile déclencheur 600 relié cinématiquement à la deuxième source d'énergie 22 et tournant toujours dans le même sens, et qui est agencé pour coopérer, au niveau d'une palette 601 que comporte le mobile déclencheur 600, avec une came 621 que comporte un mobile de came 620 relié cinématiquement au bras 1.And the movement 500 comprises, for the periodic control of a retrograde movement of the arm 1, a triggering mobile 600 kinematically connected to the second energy source 22 and always rotating in the same direction, and which is arranged to cooperate, at the level of a pallet 601 that comprises the trigger mobile 600, with a cam 621 that comprises a cam mobile 620 kinematically connected to the arm 1.

Cette came 621 couvre un secteur angulaire inférieur à 360° et qui correspond à un mouvement d'avance du bras 1 en pivotement dans un premier sens direct E à une première vitesse constante par rapport à la structure fixe 110 aussi longtemps que la palette 601 est en appui sur la came 621. Une interruption de la came 621 est agencée pour déclencher une chute de la palette 601 du mobile déclencheur 600 sous l'action du couple moteur de la deuxième source d'énergie 22, et pour commander un retour rétrograde rapide du bras 1 dans un deuxième sens rétrograde F par rapport à la structure fixe 110 à une deuxième vitesse supérieure à la première vitesse, pendant la chute de la palette 601 entre l'instant où elle quitte la came 621 et l'instant où elle revient en appui sur la came 621, le mobile de came 620 effectuant, pendant la chute, un pivotement rétrograde sous l'effet du retour rétrograde du bras 1.This cam 621 covers an angular sector less than 360 ° and which corresponds to an advance movement of the arm 1 in pivoting in a first direct direction E at a first constant speed relative to the fixed structure 110 as long as the pallet 601 is pressing on cam 621. An interruption of the cam 621 is arranged to trigger a fall of the pallet 601 of the triggering mobile 600 under the action of the engine torque of the second energy source 22, and to command a rapid retrograde return of the arm 1 in a second retrograde direction F relative to the fixed structure 110 at a second speed greater than the first speed, during the fall of the pallet 601 between the moment when it leaves the cam 621 and the moment when it comes to bear on the cam 621, the mobile cam 620 performing, during the fall, a retrograde pivoting under the effect of the retrograde return of the arm 1.

Le mécanisme selon l'invention comporte ainsi deux branches, l'une alimentée par la première source d'énergie 12, l'autre par la deuxième source d'énergie 22, et le point de convergence de ces deux branches est la zone de coopération entre le mobile déclencheur 600 et le mobile de came 620. Cette coopération est périodique, car sa période est déterminée par l'oscillateur du tourbillon, notamment un balancier-spiral ou similaire.The mechanism according to the invention thus comprises two branches, one supplied by the first energy source 12, the other by the second energy source 22, and the point of convergence of these two branches is the cooperation zone between the trigger mobile 600 and the cam mobile 620. This cooperation is periodic, since its period is determined by the oscillator of the tourbillon, in particular a balance-spring or the like.

Nous allons examiner successivement ces deux branches depuis leur alimentation en énergie.We will successively examine these two branches from their energy supply.

Le bras pivotant rétrograde 1 est ici pivoté sur la platine ou sur une structure 110 que comporte le mouvement 500. La première source d'énergie 12 comporte ici, non limitativement, au moins un ressort de bras de cage 120, fixé à une première extrémité au bras pivotant rétrograde 1, et à la platine ou la structure 110 à son autre extrémité ; sur les figures, et de façon non limitative, ce ressort de bras de cage 120 est un ressort spiral.The retrograde pivoting arm 1 is here pivoted on the plate or on a structure 110 which comprises the movement 500. The first energy source 12 here comprises, without limitation, at least one cage arm spring 120, fixed at a first end to the retrograde pivoting arm 1, and to the plate or the structure 110 at its other end; in the figures, and without limitation, this cage arm spring 120 is a spiral spring.

Un bloc regroupe, montés coaxiaux autour de l'axe D0 et libres l'un par rapport à l'autre, d'une part le bras pivotant rétrograde 1 en forme de huit qui est porteur d'une cage 150 sur sa partie excentrée, et qui porte une première extrémité d'un ressort de bras de cage, et d'autre part un mobile de pas de cage 700 qui comporte une première roue inférieure 680 et une deuxième roue intermédiaire 670 espacées axialement et solidaires en rotation, et qui sont aussi coaxiales et espacées axialement d'un secteur denté 660 (ou d'une denture complète) que comporte le bras pivotant rétrograde 1.A block groups together, mounted coaxial around the axis D0 and free relative to each other, on the one hand the retrograde pivoting arm 1 in the shape of an eight which carries a cage 150 on its eccentric part, and which carries a first end of a cage arm spring, and on the other hand a cage pitch mobile 700 which comprises a first lower wheel 680 and a second intermediate wheel 670 axially spaced and integral in rotation, and which are also coaxial and axially spaced from a toothed sector 660 (or a complete toothing) which comprises the retrograde pivoting arm 1.

Le mobile de pas de cage 700 comportant la première roue inférieure 680 et la deuxième roue intermédiaire 670 est bloqué ou libéré selon la position relative du mobile déclencheur 600 et du mobile de came 620, comme cela va être exposé ci-après. Ce mobile de pas de cage 700 constitue une roue de pas de 120° SIAM (sens inverse des aiguilles d'une montre).The cage pitch mobile 700 comprising the first lower wheel 680 and the second intermediate wheel 670 is blocked or released depending on the relative position of the trigger mobile 600 and the cam mobile 620, as will be explained below. This cage pitch mobile 700 constitutes a pitch wheel of 120 ° SIAM (anticlockwise).

Le bras pivotant rétrograde 1 porte une roue fixe 720 de tourbillon, avec laquelle coopère le pignon d'une roue d'échappement d'un mécanisme d'échappement non détaillé ici car classique, par exemple un échappement à ancre suisse coopérant avec un balancier-spiral non représenté sur les figures où seule est visible la roue d'échappement. Notamment mais non limitativement la fréquence imposée est d'une rotation de cage par minute.The retrograde pivoting arm 1 carries a fixed tourbillon wheel 720, with which the pinion of an escape wheel of an escape mechanism cooperates, which is not detailed here because it is conventional, for example a Swiss anchor escapement cooperating with a balance wheel. hairspring not shown in the figures where only the escape wheel is visible. In particular but not limited to the imposed frequency is one rotation of the cage per minute.

De ce fait, le bras pivotant rétrograde 1 ne peut parcourir qu'une course angulaire d'au maximum 120° en une minute, correspondant à une révolution complète de la cage : dans un sens direct pendant environ cinquante-huit secondes de parcours à vitesse lente du bras 1 dans la première course élémentaire, et environ deux secondes de retour rapide dans un sens rétrograde du bras 1 dans la deuxième course élémentaire.As a result, the retrograde pivoting arm 1 can only travel an angular travel of maximum 120 ° in one minute, corresponding to a complete revolution of the cage: in a direct direction for approximately fifty-eight seconds of travel at speed slow of arm 1 in the first elementary stroke, and approximately two seconds of rapid return in a retrograde direction of arm 1 in the second elementary stroke.

Le secteur denté 660 engrène, directement, ou indirectement comme sur les figures, avec un mobile de came 620, qui subit donc des mouvements directs ou rétrogrades comme le bras pivotant rétrograde 1 : quand le bras pivotant rétrograde 1 pivote dans le sens direct E, le mobile de came 620 pivote dans un sens direct H, et, quand le bras pivotant rétrograde 1 pivote dans le sens rétrograde F, le mobile de came 620 pivote dans un sens rétrograde J.The toothed sector 660 meshes, directly, or indirectly as in the figures, with a cam mobile 620, which therefore undergoes direct or retrograde movements like the retrograde pivoting arm 1: when the retrograde pivoting arm 1 pivots in the direct direction E, the cam mobile 620 pivots in a direct direction H, and, when the retrograde pivoting arm 1 pivots in the retrograde direction, the cam mobile 620 pivots in a retrograde direction J.

Dans la variante des figures le secteur denté 660 engrène indirectement avec le mobile de came 620 au travers d'un rouage, qui est non limitativement illustré ici par un premier renvoi 630 et un deuxième renvoi 640 porteur d'un pignon 650. Dans une version particulière, ce rouage de came comporte au moins un composant réglable par friction ou similaire : par exemple, le deuxième renvoi 640 peut comporter deux chaussées lanternées coopérant par friction entre elles pour un réglage fin en usine ou en SAV de l'orientation angulaire du pignon supérieur 650 par rapport à l'autre denture inférieure que porte ce deuxième renvoi 640, pour ajuster si nécessaire l'angle rétrograde de 120°, ou autre.In the variant of the figures, the toothed sector 660 meshes indirectly with the cam mobile 620 through a gear train, which is non-limitatively illustrated here by a first reference 630 and a second reference 640 carrying a pinion 650. In a version particular, this cam train comprises at least one component adjustable by friction or the like: for example, the second reference 640 may comprise two lanterned carriageways cooperating by friction with one another for fine adjustment in the factory or in after-sales service of the angular orientation of the pinion upper 650 with respect to the other lower toothing carried by this second reference 640, to adjust if necessary the retrograde angle of 120 °, or the like.

Ce mobile de came 620 comporte ou porte une came 621, qui couvre un secteur angulaire inférieur à 360° et qui correspond à un mouvement d'avance du bras pivotant rétrograde 1, l'interruption de la came 621 étant agencée pour déclencher une chute d'une palette 611 que comporte le mobile déclencheur 600, et pour commander un retour rétrograde rapide du bras pivotant rétrograde 1.This cam mobile 620 comprises or carries a cam 621, which covers an angular sector of less than 360 ° and which corresponds to a forward movement of the retrograde pivoting arm 1, the interruption of the cam 621 being arranged to trigger a fall d 'a pallet 611 that includes the trigger mobile 600, and for controlling a rapid retrograde return of the retrograde pivoting arm 1.

Ce mobile de came 620 a des rotations alternées dans les deux sens, selon le sens de mouvement angulaire du bras pivotant rétrograde 1.This cam mobile 620 has alternating rotations in both directions, according to the direction of angular movement of the retrograde pivoting arm 1.

Plus particulièrement, cette came 621 est une came à couple linéaire, avec une piste coaxiale à l'axe du mobile de came 620. Cette came 621 couvre un secteur angulaire inférieur à 360°, choisi en fonction de la cinématique souhaitée, et est prolongée par un dégagement 623. La came 621 comporte une pointe de came 622 à l'une de ses extrémités.More particularly, this cam 621 is a cam with linear torque, with a track coaxial with the axis of the cam mobile 620. This cam 621 covers an angular sector less than 360 °, chosen as a function of the desired kinematics, and is extended by a clearance 623. The cam 621 has a cam tip 622 at one of its ends.

Si, dans la variante préférée illustrée par les figures, la piste de la came 621 est cylindrique, on comprend que son profil pourrait être autre que circulaire, sans altérer sa fonction d'animation du mécanisme rétrograde. L'emploi d'un autre profil, avec une came de forme particulière, autorise des manoeuvres particulières des afficheurs, par exemple pour réaliser des évitements de certaines zones, au prix d'une légère consommation d'énergie.If, in the preferred variant illustrated by the figures, the track of the cam 621 is cylindrical, it is understood that its profile could be other than circular, without altering its function of animation of the retrograde mechanism. The use of another profile, with a cam of particular shape, allows particular operations of the displays, for example to avoid certain areas, at the cost of a slight consumption of energy.

Considérons maintenant la deuxième branche du mécanisme.Now consider the second branch of the mechanism.

La deuxième source d'énergie 22 comporte ici, non limitativement, au moins un barillet principal, qui est rechargé en énergie par des moyens connus, les figures illustrent plus particulièrement et non limitativement un barillet principal 22 unique, réarmé au travers d'un rouage de remontage, non détaillé ici, par une tige de mise à l'heure et de remontage 2200, agencée pour être actionnée par la couronne 220. Naturellement cette deuxième source d'énergie 22 peut être de toute nature usuelle en horlogerie, par exemple une source électrique apte à entraîner un mobile en rotation, ou autre. Ce barillet principal 22 entraîne ici classiquement un rouage de finissage, qui comporte un mobile de grande moyenne 601, et un mobile de petite moyenne 602. Ce dernier entraîne un mobile de finissage 603.The second energy source 22 here includes, without limitation, at least one main cylinder, which is recharged with energy by known means, the figures illustrate more particularly and without limitation a single main cylinder 22, rearmed through a gear train winding, not detailed here, by a time-setting and winding rod 2200, arranged to be actuated by the crown 220. Naturally, this second source of energy 22 can be of any kind customary in watchmaking, for example a electrical source capable of driving a mobile in rotation, or other. This main barrel 22 conventionally drives a finishing train here, which comprises a large medium mobile 601, and a small medium mobile 602. The latter drives a finishing mobile 603.

Plus particulièrement, la deuxième source d'énergie 22 entraîne, au travers du rouage de finissage, le mobile de finissage 603, qui entraîne un mobile déclencheur 600, qui tourne toujours dans le même sens.More particularly, the second energy source 22 drives, through the gear train, the finishing mobile 603, which drives a trigger mobile 600, which always turns in the same direction.

Ce mobile déclencheur 600 comporte une roue du doigt déclencheur 610, laquelle engrène avec le mobile de finissage 603. Tel que visible notamment sur la figure 30, cette roue du doigt déclencheur 610 est montée coaxiale, autour d'un axe 619, avec un doigt déclencheur 615 porteur d'une palette 611.This trigger mobile 600 comprises a trigger finger wheel 610, which meshes with the finishing mobile 603. As visible in particular on the figure 30 , this wheel of the trigger finger 610 is mounted coaxially, around an axis 619, with a trigger finger 615 carrying a pallet 611.

De préférence, la roue du doigt déclencheur 610 et le doigt déclencheur 615 ont une petite mobilité angulaire d'angle α d'un par rapport à l'autre, de l'ordre de quelques degrés, et notamment de moins de 15 degrés.Preferably, the wheel of the trigger finger 610 and the trigger finger 615 have a small angular mobility of angle α from one relative to the other, of the order of a few degrees, and in particular of less than 15 degrees.

De façon avantageuse, la roue du doigt déclencheur 610 porte ou comporte un bras-ressort 612, dont une extrémité distale formant marteau 613 est agencée pour coopérer en appui de butée avec une goupille 614 que porte le doigt déclencheur 615. La roue du doigt déclencheur 610 comporte, d'une part une surface de butée arrière 618 pour limiter la course angulaire relative de la goupille 614, et d'autre part une surface de butée avant 617 pour limiter la course angulaire du marteau 613. Le bras-ressort 612 est ici monobloc avec la roue du doigt déclencheur 610 et est mobile dans une lumière 6120 que comporte cette dernière, et dont des surfaces intérieures limitent la course radiale du bras-ressort 612 ; le bras-ressort 612 peut, encore, être un élément rapporté, dont la course radiale est alors limitée par des surfaces de butée ménagées à cet effet. Dans une autre exécution, l'ensemble du mobile déclencheur 600 est un composant monobloc.Advantageously, the wheel of the trigger finger 610 carries or comprises a spring arm 612, one distal end of which forms a hammer 613 is arranged to cooperate in abutment support with a pin 614 which the trigger finger 615 carries. The wheel of the trigger finger 610 comprises, on the one hand a rear abutment surface 618 for limiting the relative angular travel of the pin 614, and on the other hand a front abutment surface 617 for limiting the angular travel of the hammer 613. The spring arm 612 is here monobloc with the wheel of the trigger finger 610 and is movable in a light 6120 which the latter comprises, and whose internal surfaces limit the radial stroke of the spring arm 612; the spring arm 612 can also be an added element, the radial stroke of which is then limited by abutment surfaces provided for this purpose. In another embodiment, the entire trigger mobile 600 is a one-piece component.

Considérons maintenant la coopération entre le mobile déclencheur 600 et le mobile de came 620.Now consider the cooperation between the trigger mobile 600 and the cam mobile 620.

Au niveau de la roue de came 620, la piste de la came 621 est prévue pour servir d'appui à la palette 611 du doigt déclencheur 610 : tant que la palette 611 est en appui sur la piste de la came 621, le bras pivotant rétrograde 1 est animé d'un mouvement d'avance régulier dans le sens direct, jusqu'à ce que la pointe de la palette 611 vienne en appui sur la pointe de came 622, dernier instant précédant la chute de la palette 611 : Le dégagement 623 de la roue de came 620 est prévu pour autoriser, sans lui faire obstacle, le passage de la palette 611 le long du mobile de came 620 : lorsque la pointe de la palette 611 quitte la pointe de came 622, la palette 611 chute et effectue un mouvement rapide sous l'effet d'entraînement du rouage de finissage, ce mouvement rapide commence par le passage de la palette 611 dans le dégagement 623, puis la palette 611 quitte l'emprise du mobile de came 620, et la roue du doigt déclencheur 610 tend à faire un tour complet autour de son axe, jusqu'au retour en appui de la palette 611 sur la piste de la came 621. Cette came 621 a aussi tourné dans l'intervalle. En effet, lors de la séparation de la palette 611 et de la came 621, plus rien ne retient la roue de came 620, ni par conséquent le bras pivotant rétrograde 1 qui est rappelé en mouvement rétrograde rapide sous l'action du ressort de bras de cage 120, et bien sûr la roue de came 620 effectue aussi un tel mouvement rétrograde pendant environ 2 secondes.At the level of the cam wheel 620, the track of the cam 621 is provided to serve as a support for the pallet 611 of the trigger finger 610: as long as the pallet 611 is in abutment on the track of the cam 621, the pivoting arm retrograde 1 is animated with a regular forward movement in the direct direction, until the tip of the pallet 611 comes to bear on the cam tip 622, last instant preceding the fall of the pallet 611: The release 623 of the cam wheel 620 is provided to allow, without obstructing it, the passage of the pallet 611 along the cam mobile 620: when the tip of the pallet 611 leaves the cam tip 622, the pallet 611 drops and performs a rapid movement under the driving effect of the finishing train, this rapid movement begins with the passage of the pallet 611 in the clearance 623, then the pallet 611 leaves the grip of the cam mobile 620, and the wheel of the trigger finger 610 tends to make a full turn around its axis e, until the pallet 611 returns to bear on the track of the cam 621. This cam 621 has also rotated in the meantime. Indeed, during the separation of the pallet 611 and the cam 621, nothing more retains the cam wheel 620, nor consequently the retrograde pivoting arm 1 which is returned in rapid retrograde movement under the action of the arm spring cage 120, and of course the cam wheel 620 also performs such a retrograde movement for about 2 seconds.

Pendant cette course de retour rapide la vitesse des mobiles, et notamment du mobile déclencheur 600, est limitée par un mobile de régulateur 604, comportant par exemple une étoile engrenant avec le mobile de finissage 603 et coopérant avec une ancre de régulateur 605.During this rapid return stroke, the speed of the mobiles, and in particular of the trigger mobile 600, is limited by a regulator mobile 604, comprising for example a star meshing with the finishing mobile 603 and cooperating with a regulator anchor 605.

La deuxième roue intermédiaire 670 du mobile de pas de cage 700 engrène avec un pignon de cage 710 qui entraîne la cage 150, tel que visible sur la figure 22. Cette même figure 22 montre encore l'engrènement entre un renvoi 690, avec lequel engrène le mobile déclencheur 600, avec la première roue inférieure 680 du mobile de pas de cage 700.The second intermediate wheel 670 of the cage pitch mobile 700 meshes with a cage pinion 710 which drives the cage 150, as visible on the figure 22 . This same figure 22 still shows the meshing between a reference 690, with which the trigger mobile 600 meshes, with the first lower wheel 680 of the cage pitch mobile 700.

On comprend donc que, tant que la palette 611 du mobile déclencheur 610 est en contact avec la piste de came 621 de la roue de came 620, le mobile de pas de cage 700 est maintenu à l'arrêt par le renvoi 690 qui engrène avec le mobile déclencheur 610, qui est immobile. Quand la palette chute, l'énergie du barillet principal 22 est libérée, et provoque la rotation rapide, toutefois freinée par l'ancre 605, du rouage de finissage et du mobile de pas de cage 700, qui entraîne dans sa rotation le pignon de cage 710.It is therefore understood that, as long as the pallet 611 of the trigger mobile 610 is in contact with the cam track 621 of the cam wheel 620, the cage pitch mobile 700 is kept stationary by the reference 690 which meshes with the trigger mobile 610, which is stationary. When the pallet drops, the energy of the main barrel 22 is released, and causes the rapid rotation, however braked by the anchor 605, of the finishing train and of the cage pitch mobile 700, which drives in its rotation the pinion of cage 710.

Pendant les deux secondes de la chute le mobile de pas de cage 700, qui est indépendant du bras pivotant rétrograde 1, tourne, et entraîne ainsi la cage de tourbillon, jusqu'à la fin de la chute, et le mobile de pas de cage 700 est alors arrêté. Naturellement la cage de tourbillon a poursuivi sa rotation, toujours dans le même sens et à la même vitesse, pendant la durée de la chute. Pendant la chute la roue de came 620 est entraînée dans son sens rétrograde J, et, à la fin de la chute, se présente dans une position angulaire dans laquelle la came 621 reçoit en la palette 611 en appui radial.During the two seconds of the fall, the cage pitch mobile 700, which is independent of the retrograde pivoting arm 1, rotates, and thus drives the tourbillon cage, until the end of the fall, and the cage pitch mobile 700 is then stopped. Naturally the tourbillon cage continued its rotation, always in the same direction and at the same speed, during the duration of the fall. During the fall the cam wheel 620 is driven in its retrograde direction J, and, at the end of the fall, is in an angular position in which the cam 621 receives in the pallet 611 in radial support.

Lorsque le bras pivotant rétrograde 1 revient en position de départ et reprend sa course en sens direct, le mobile de pas de cage 700 est, ainsi, à l'arrêt.When the retrograde pivoting arm 1 returns to the starting position and resumes its travel in the direct direction, the cage pitch mobile 700 is thus stopped.

En somme, la roue de came 620 a un mouvement alternatif à déclenchement périodique, dont la période dépend de la fréquence de l'oscillateur du tourbillon.In short, the cam wheel 620 has an alternating movement with periodic triggering, the period of which depends on the frequency of the oscillator of the vortex.

On comprend que, ici, les deux sources d'énergie ont des fonctions différentes : le barillet principal du mouvement 500, qui est ici la deuxième source d'énergie 22, définit la réserve de marche, alimente le système, mais n'alimente pas le résonateur en direct ; tandis que la première source d'énergie 12 ici constituée par le ressort de cage 120 (qui pourrait aussi être un barillet, ou autre), entraîne le mobile de came 620 porteur de la came 621, commande dans cet exemple particulier l'armage/désarmage de 120°, alimente l'oscillateur, et effectue les mouvements +120° et -120°; la deuxième source d'énergie 22 réalimente en permanence la première source d'énergie 12._It is understood that, here, the two energy sources have different functions: the main barrel of the movement 500, which is here the second energy source 22, defines the power reserve, supplies the system, but does not supply the live resonator; while the first energy source 12 here constituted by the cage spring 120 (which could also be a barrel, or the like), drives the cam mobile 620 carrying the cam 621, in this particular example controls the arming / 120 ° disarm, powers the oscillator, and performs movements + 120 ° and -120 °; the second energy source 22 continuously replenishes the first energy source 12._

Les figures 32 à 34 illustrent une variante du mécanisme des figures 15 à 31, avec le bloc composé du bras et du mobile de pas de cage est séparé de la première source d'énergie, qui est déportée sur la platine ou structure fixe 110, et qui comporte une première roue 1200 coopérant avec le ressort de bras de cage 120, et qui engrène avec le secteur denté 660 du bras pivotant rétrograde 1. Dans ce mécanisme les rouages sont représentés de façon simplifiée, pour mettre en évidence les deux branches de circulation d'énergie :

  • la branche alimentée par la première source d'énergie 12 comporte successivement cette première roue 1200, le bras pivotant rétrograde 1 avec la roue fixe de tourbillon 720, un renvoi 650, et la roue de came 620 ;
  • la branche alimentée par la deuxième source d'énergie 22 comporte successivement, depuis le dessous du mouvement visible sur la figure 34, le barillet principal, une roue de moyenne 601 dont l'arbre traverse la platine ou structure fixe 110, le mobile de pas de cage 700 (dont la deuxième roue intermédiaire 670 engrène avec le pignon de cage non représenté ici), le mobile de renvoi 690 et un autre renvoi, puis le mobile déclencheur 610.
The figures 32 to 34 illustrate a variant of the mechanism of Figures 15 to 31 , with the block composed of the arm and of the cage pitch mobile is separated from the first source of energy, which is offset on the plate or fixed structure 110, and which comprises a first wheel 1200 cooperating with the cage arm spring 120, and which meshes with the toothed sector 660 of the retrograde pivoting arm 1. In this mechanism the cogs are represented in a simplified manner, to highlight the two branches of energy circulation:
  • the branch supplied by the first energy source 12 successively comprises this first wheel 1200, the retrograde pivoting arm 1 with the fixed tourbillon wheel 720, a reference 650, and the cam wheel 620;
  • the branch supplied by the second energy source 22 successively comprises, from below the movement visible on the figure 34 , the main barrel, a medium wheel 601 whose shaft crosses the plate or fixed structure 110, the cage pitch mobile 700 (including the second intermediate wheel 670 meshes with the cage pinion not shown here), the mobile reference 690 and another reference, then the trigger mobile 610.

Le fonctionnement du mécanisme est ainsi assuré par des chaînes cinématiques courtes, comportant peu de composants, lesquels sont d'exécution facile et économique. L'invention permet de réaliser une complication innovante avec une faible consommation d'espace dans la boîte de la montreThe operation of the mechanism is thus ensured by short kinematic chains, comprising few components, which are easy and economical to execute. The invention makes it possible to produce an innovative complication with a low consumption of space in the watch case
