Description

La présente invention a pour objet un mouvement d'horlogerie comprenant un organe réglant oscillant destiné à réguler un rouage du mouvement, un mécanisme de mise à l'heure et un mécanisme d'arrêt et de relance permettant d'arrêter et de relancer les oscillations de l'organe réglant oscillant.The subject of the present invention is a watch movement comprising an oscillating regulating member intended to regulate a cog of the movement, a time setting mechanism and a stopping and restarting mechanism making it possible to stop and restart the oscillations of the oscillating regulating organ.

Lors de la mise à l'heure d'un mouvement d'horlogerie, l'organe réglant oscillant est généralement arrêté lorsque la tige de mise à l'heure est tirée. Si le mécanisme d'échappement utilisé dans le mouvement est auto-démarrant, il n'y aura pas de problème lors de la fin de la mise à l'heure : la tige de mise à l'heure est repoussée et l'échappement et l'organe réglant oscillant redémarrent. C'est le cas des mécanismes d'échappement à ancre classiques.When setting the time of a watch movement, the oscillating regulating member is generally stopped when the time setting stem is pulled. If the escapement mechanism used in the movement is self-starting, there will be no problem when the time setting is completed: the time setting stem is pushed back and the escapement and the oscillating regulating organ restarts. This is the case with classic lever escapement mechanisms.

Dans le cas d'un mécanisme d'échappement non auto-démarrant, comme un échappement à détente, il est nécessaire de prévoir un dispositif pour relancer les oscillations de l'organe réglant oscillant à la fin de la mise à l'heure.In the case of a non-self-starting escapement mechanism, such as a detent escapement, it is necessary to provide a device to restart the oscillations of the oscillating regulating member at the end of time setting.

Le but de la présente invention est de fournir un mouvement d'horlogerie comprenant un mécanisme d'arrêt et de relance de l'organe réglant oscillant qui permette de relancer efficacement l'organe réglant oscillant dans tous les cas, quel que soit le mécanisme d'échappement associé, avec un angle de relance le plus grand possible et tout en restant simple et peu encombrant.The aim of the present invention is to provide a clock movement comprising a mechanism for stopping and restarting the oscillating regulating member which makes it possible to effectively restart the oscillating regulating member in all cases, whatever the mechanism. associated exhaust, with the largest possible recovery angle while remaining simple and space-saving.

La présente invention a pour objet un mouvement d'horlogerie selon la revendication 1 ainsi qu'une pièce d'horlogerie selon la revendication 6.The subject of the present invention is a timepiece movement according to claim 1 as well as a timepiece according to claim 6.

Les figures annexées illustrent schématiquement une forme d'exécution du mouvement d'horlogerie selon l'invention.The appended figures schematically illustrate an embodiment of the clock movement according to the invention.

Les figures 1 et 2 illustrent en particulier l'organe réglant oscillant et le mécanisme d'arrêt et de relance de celui-ci d'un mouvement selon une forme d'exécution de l'invention, le mécanisme d'arrêt et de relance de l'organe réglant oscillant étant dans sa position de repos dans la figure 1 et dans sa position d'arrêt dans la figure 2.THE figures 1 And 2 illustrate in particular the oscillating regulating member and the mechanism for stopping and restarting a movement thereof according to one embodiment of the invention, the mechanism for stopping and restarting the regulating member oscillating being in its rest position in the figure 1 and in its stopping position in the figure 2 .

Le mouvement d'horlogerie selon l'invention comprend un organe réglant oscillant destiné à réguler un rouage du mouvement, un mécanisme de mise à l'heure commandé par un organe de commande actionnable par un utilisateur entre une positon de repos et une position de mise à l'heure et un mécanisme d'arrêt et de relance de l'organe réglant commandé par ledit organe de commande. Dans la forme d'exécution illustrée, l'organe réglant oscillant 1 est un balancier-spiral comprenant un balancier 10 et un spiral 11. En variante, l'organe réglant pourrait être un oscillateur à guidage flexible.The watch movement according to the invention comprises an oscillating regulating member intended to regulate a cog of the movement, a time setting mechanism controlled by a control member operable by a user between a rest position and a setting position on time and a mechanism for stopping and restarting the regulating member controlled by said control member. In the illustrated embodiment, the oscillating regulating member 1 is a sprung balance comprising a balance 10 and a hairspring 11. Alternatively, the regulating member could be an oscillator with flexible guidance.

Dans la forme d'exécution illustrée, le mouvement comprend un mécanisme de mise à l'heure bien connu de l'homme du métier et dont seule la tirette 2 est visible. Le mécanisme de mise à l'heure et les déplacements de la tirette 2 sont notamment commandés par u une tige de mise à l'heure non illustrée.In the illustrated embodiment, the movement includes a time setting mechanism well known to those skilled in the art and of which only the pull tab 2 is visible. The time setting mechanism and the movements of the pull tab 2 are in particular controlled by a time setting rod not shown.

Dans la forme d'exécution illustrée, le mécanisme d'arrêt et de relance du balancier-spiral 1 comprend une bascule 3 montée pivotante en A sur une partie fixe du mouvement et présentant un premier bras 31 destiné à coopérer avec la tirette 2. Pour ce faire, le premier bras 31 comprend à son extrémité une fente 311 dans laquelle vient se loger un plot 4 fixée sur la tirette 2. Ainsi, lorsque la tirette 2 pivote, elle entraîne la bascule 3 qui pivote à son tour. La bascule 3 est agencée pour pivoter entre une première position de repos illustrée à la figure 1, qui correspondant à la position poussée de la tige de mise à l'heure (fonctionnement normal du mouvement), et une position d'arrêt illustrée à la figure 2, qui correspond à la position tirée de la tige de mise à l'heure (mise à l'heure du mouvement).In the illustrated embodiment, the mechanism for stopping and restarting the sprung balance 1 comprises a rocker 3 pivotally mounted at A on a fixed part of the movement and having a first arm 31 intended to cooperate with the pull tab 2. To do this, the first arm 31 comprises at its end a slot 311 in which a stud 4 fixed on the zipper 2 is housed. Thus, when the zipper 2 pivots, it drives the rocker 3 which pivots in turn. The rocker 3 is arranged to pivot between a first rest position illustrated in figure 1 , which corresponds to the pushed position of the time setting stem (normal operation of the movement), and a stop position illustrated in figure 2 , which corresponds to the pulled position of the time setting stem (setting the time of the movement).

La bascule 3 comprend en outre un second bras 32 qui possède à son extrémité une denture 321.The rocker 3 further comprises a second arm 32 which has teeth 321 at its end.

Le mécanisme d'arrêt et de relance du balancier-spiral 1 comprend encore un levier stop 5 pivoté en B sur un partie fixe du mouvement d'horlogerie. Le levier stop 5 comprend une denture 51 en prise avec la denture 321 du second bras 32 de la bascule 3. Ainsi, lorsque la bascule 3 pivote de sa positon de repos à sa position d'arrêt, elle entraîne à son tour le levier stop 5 qui pivote également de sa position de repos à sa position d'arrêt.The mechanism for stopping and restarting the sprung balance 1 also includes a stop lever 5 pivoted at B on a fixed part of the clock movement. The lever stop 5 includes teeth 51 engaged with teeth 321 of the second arm 32 of rocker 3. Thus, when rocker 3 pivots from its rest position to its stopping position, it in turn drives stop lever 5 which also pivots from its rest position to its stop position.

Le levier stop 5 comprend en outre un bras élastique 52 agencé pour venir en contact avec le balancier 10 du balancier-spiral 1 tangentiellement à celui-ci. Dans sa position de repos, le levier stop 5 est agencé pour que son bras élastique 52 soit en contact avec une goupille 6 fixée dans le mouvement d'horlogerie, ledit contact générant une mise en contrainte ou un pré-armage dudit bras élastique 52. Cette précontrainte ou ce préarmage, qui peut être léger, permet de rattraper les jeux dans le mécanisme d'arrêt et de relance de l'organe réglant oscillant et donc permet d'éviter que le levier stop 5 ne bouge lorsqu'il est dans sa position de repos.The stop lever 5 further comprises an elastic arm 52 arranged to come into contact with the balance 10 of the sprung balance 1 tangentially thereto. In its rest position, the stop lever 5 is arranged so that its elastic arm 52 is in contact with a pin 6 fixed in the clock movement, said contact generating stress or pre-arming of said elastic arm 52. This preload or this preload, which can be light, makes it possible to compensate for the play in the stopping and restarting mechanism of the oscillating regulating member and therefore makes it possible to prevent the stop lever 5 from moving when it is in its position. rest position.

En fonctionnement normal du mouvement, la tige de mise à l'heure est dans sa position poussée, la tirette 2 est dans sa position de repos. La bascule 3 et le levier stop 5 sont donc également dans leur position de repos respective, le bras élastique 52 du levier stop 5 étant en appui avec précontrainte sur la goupille 6. Dans cette configuration, illustrée à la figure 1, l'organe réglant 1 formé du balancier 10 et du spiral 11 oscille, régulant ainsi un rouage du mouvement, ses oscillations étant entretenues par un mécanisme d'échappement.In normal operation of the movement, the time setting stem is in its pushed position, pull tab 2 is in its rest position. The rocker 3 and the stop lever 5 are therefore also in their respective rest position, the elastic arm 52 of the stop lever 5 being supported with preload on the pin 6. In this configuration, illustrated in figure 1 , the regulating member 1 formed of the balance 10 and the hairspring 11 oscillates, thus regulating a cog of the movement, its oscillations being maintained by an escapement mechanism.

Lorsque l'utilisateur effectue une mise à l'heure, la tige de mise à l'heure est déplacée dans sa position tirée. Elle déplace alors la tirette 2 dans sa position de mise à l'heure. Ce faisant, la tirette 2 entraîne la bascule 3 qui pivote dans sa position d'arrêt emmenant avec elle le levier-stop 5 grâce à l'engrenage des dentures 321 et 51. En pivotant, le bras élastique 52 du levier stop 5 vient en contact contre le balancier 10 tangentiellement à celui-ci. Le mécanisme d'arrêt et de relance de l'organe réglant selon l'invention est agencé pour que, lorsque le levier stop 5 pivote dans sa position d'arrêt, le bras élastique 52 vient en contact avec le balancier 10 et entraîne celui-ci brièvement d'un certain angle, qu'on appellera angle de relance (dans le sens horaire dans la figure 2) avant de le freiner et de le stopper complètement dès que la position d'arrêt du levier stop 5 est atteinte. De préférence, le levier stop 5 est agencé pour entraîner le balancier 10 d'un angle de relance supérieur à 20°, de manière encore plus privilégiée d'un angle de relance supérieur à 25° lorsqu'il pivote de sa position de repos dans sa positon d'arrêt.When the user sets the time, the time setting stem is moved to its pulled position. It then moves pull tab 2 to its time setting position. In doing so, the pull tab 2 drives the rocker 3 which pivots into its stopping position taking with it the stop lever 5 thanks to the gearing of the teeth 321 and 51. By pivoting, the elastic arm 52 of the stop lever 5 comes into contact against the balance 10 tangentially thereto. The stopping and restarting mechanism of the regulating member according to the invention is arranged so that, when the stop lever 5 pivots into its stopping position, the elastic arm 52 comes into contact with the balance 10 and drives it. briefly from a certain angle, that we will call raise angle (clockwise in the figure 2 ) before braking it and stopping it completely as soon as the stopping position of stop lever 5 is reached. Preferably, the stop lever 5 is arranged to drive the balance 10 by a restart angle greater than 20°, even more preferably by a restart angle greater than 25° when it pivots from its rest position in its stopping position.

Dans la position d'arrêt du levier-stop 5 illustrée à la figure 2, l'organe réglant 1 est arrêté et n'oscille plus. L'utilisateur peut alors effectuer la mise à l'heure de manière conventionnelle via la tige de mise à l'heure.In the stopping position of the stop lever 5 illustrated in figure 2 , regulating organ 1 is stopped and no longer oscillates. The user can then set the time conventionally via the time setting stem.

Lorsque la mise à l'heure est effectuée et que l'utilisateur repousse la tige de mise à l'heure dans sa position poussée, la tirette 2 reprend sa position de repos et entraîne donc la bascule 3 et le levier stop 5 qui pivotent chacun pour retrouver leur position de repos. Ce faisant, le bras élastique 52 du levier stop 5 en contact avec le balancier 10 va, grâce aux frottements, relancer le balancier-spiral 1 en faisant pivoter le balancier 10 dans le sens anti-horaire dans les figures d'un angle correspondant essentiellement à l'angle de relance défini ci-dessus. L'organe réglant oscillant 1 est relancé et le mouvement peut redémarrer quel que soit le mécanisme d'échappement utilisé.When the time is set and the user pushes the time setting rod back into its pushed position, the pull tab 2 returns to its rest position and therefore drives the rocker 3 and the stop lever 5 which each pivot to return to their resting position. In doing so, the elastic arm 52 of the stop lever 5 in contact with the balance 10 will, thanks to friction, restart the sprung balance 1 by rotating the balance 10 in the counterclockwise direction in the figures by an angle essentially corresponding at the recovery angle defined above. The oscillating regulating member 1 is restarted and the movement can restart regardless of the escapement mechanism used.

Ainsi, il est possible de réaliser un mécanisme d'arrêt et de relance de l'organe réglant oscillant qui est commandé par la tige de mise à l'heure et la tirette et qui permet, grâce à l'engrenage denté entre la bascule 3 et le levier stop 5, de multiplier la course dudit levier de sorte que celui-ci peut relancer l'organe réglant avec un angle de relance important. Il est ainsi assuré que l'organe réglant oscillant redémarre après une mise à l'heure, peu importe la position dans laquelle le mouvement s'est arrêté et peu importe le mécanisme d'échappement du mouvement. Le levier stop 5 agit tangentiellement au balancier 10 ce qui garantit un mécanisme simple et peu encombrant.Thus, it is possible to produce a mechanism for stopping and restarting the oscillating regulating member which is controlled by the time-setting rod and the pull-tab and which allows, thanks to the toothed gear between the rocker 3 and the stop lever 5, to multiply the stroke of said lever so that it can restart the regulating member with a significant restart angle. It is thus ensured that the oscillating regulating member restarts after setting the time, regardless of the position in which the movement stopped and regardless of the movement escapement mechanism. The stop lever 5 acts tangentially to the balance 10, which guarantees a simple and space-saving mechanism.

Dans la forme d'exécution illustrée, l'organe réglant oscillant est un balancier spiral. En variante, l'organe réglant pourrait être d'un autre type, comme un oscillateur à guidage flexible.In the illustrated embodiment, the oscillating regulating member is a spiral balance. Alternatively, the regulating member could be of another type, such as a flexible guided oscillator.

Dans la forme d'exécution illustrée, l'organe réglant oscillant comprend une partie inertielle mobile en oscillation ayant la forme d'un balancier circulaire plein. En variante, la partie inertielle de l'organe réglant oscillant pourrait être formée de plusieurs segments circulaires ou encore pourrait présenter toute autre forme appropriée.In the illustrated embodiment, the oscillating regulating member comprises an inertial part movable in oscillation having the shape of a solid circular balance wheel. Alternatively, the inertial part of the oscillating regulating member could be formed of several circular segments or could have any other appropriate shape.

De manière générale, le mouvement d'horlogerie selon l'invention comprend un organe réglant oscillant destiné à réguler un rouage du mouvement et comprenant une partie inertielle mobile, un mécanisme de mise à l'heure commandé par un organe de commande actionnable par un utilisateur entre une positon de repos et une position de mise à l'heure et un mécanisme d'arrêt et de relance de l'organe réglant oscillant destiné à arrêter l'organe réglant oscillant lors d'une mise à l'heure du mouvement et à relancer ledit organe réglant lorsque la mise à l'heure est effectuée. Le mécanisme d'arrêt et de relance de l'organe réglant oscillant est commandé par l'organe de commande du mécanisme de mise à l'heure et comprend une bascule montée pivotante entre une position de repos et une position d'arrêt et comprenant un secteur denté destiné à coopérer avec un secteur denté correspondant d'un levier. Le levier est monté pivotant entre une position de repos et une position d'arrêt et comprend un bras élastique agencé pour venir en contact avec la partie inertielle mobile de l'organe réglant oscillant, tangentiellement à celle-ci, lorsque le levier pivote de sa position de repos dans sa position d'arrêt.Generally speaking, the watch movement according to the invention comprises an oscillating regulating member intended to regulate a cog of the movement and comprising a movable inertial part, a time setting mechanism controlled by a control member operable by a user between a rest position and a time setting position and a mechanism for stopping and restarting the oscillating regulating member intended to stop the oscillating regulating member when setting the time of the movement and to restart said regulating organ when the time is set. The mechanism for stopping and restarting the oscillating regulating member is controlled by the control member of the time setting mechanism and comprises a rocker mounted to pivot between a rest position and a stopping position and comprising a toothed sector intended to cooperate with a corresponding toothed sector of a lever. The lever is pivotally mounted between a rest position and a stopping position and comprises an elastic arm arranged to come into contact with the movable inertial part of the oscillating regulating member, tangentially thereto, when the lever pivots from its position. rest position in its stopping position.

  • en ramenant l'organe de commande dans sa position de repos, la bascule et le levier pivotent également pour retrouver leur position de repos et ce faisant, le bras élastique du levier fait pivoter la partie inertielle mobile de manière à relancer les oscillations de l'organe réglant oscillant.
