Description
L'invention concerne un module horloger. Elle concerne aussi un mouvement horloger comprenant un tel module. Elle concerne encore une pièce d'horlogerie, notamment une montre bracelet, comprenant un tel module ou un tel mouvement. Elle concerne également un procédé de production d'un système horloger. Elle concerne enfin un système horloger obtenu par un tel procédé.The invention relates to a watch module. It also relates to a watch movement comprising such a module. It also relates to a timepiece, including a wristwatch, including such a module or such a movement. It also relates to a method of producing a watch system. Finally, it relates to a clock system obtained by such a method.
Des mobiles horlogers sont généralement prévus pour coopérer avec des moyens de rappel élastique afin de permettre leur positionnement ou leur actionnement dans l'accomplissement des différentes fonctions d'un mouvement horloger. De manière usuelle, ces moyens de rappel élastique prennent la forme de ressorts, en particulier de ressorts lames ou de ressorts fils, qui sont mis en place par un horloger lors de l'assemblage du mouvement. Une telle opération de mise en place peut être délicate, notamment du fait de l'opération de mise en précontrainte du ressort, qui risque de marquer le mobile horloger. Par ailleurs, de tels ressorts requièrent un encombrement non négligeable, en particulier dans le plan du bâti du mouvement, en regard de la surface à disposition au sein du mouvement horloger. Il existe des conceptions alternatives dans lesquels des ressorts prennent la forme de rondelles ou de clinquants. L'assemblage de tels ressorts dans le mouvement peut toutefois s'avérer particulièrement délicat du fait de leur petite taille.Watchmakers are generally provided to cooperate with elastic return means to enable their positioning or actuation in the performance of the various functions of a watch movement. Usually, these elastic return means take the form of springs, in particular leaf springs or wire springs, which are put in place by a watchmaker during the assembly of the movement. Such a setting operation can be difficult, especially because of the preloading operation of the spring, which may mark the mobile watch. Moreover, such springs require a significant amount of space, especially in the plane of the frame of the movement, facing the surface available within the watch movement. There are alternative designs in which springs take the form of washers or foils. The assembly of such springs in the movement can however be particularly difficult because of their small size.

Un premier mode de réalisation d'un module horloger 100 selon l'invention est décrit ci-après en référence aux
Le module horloger 100 comprend :
- un
mobile 11 comprenant une première partie fonctionnelle 11 a, une deuxième partie fonctionnelle 11 b et unarbre 15 de translation et/ou de rotation dumobile 11, l'arbre présentant unpremier axe 151 ; - un
ressort 13, notamment un ressort hélicoïdal. - un
boîtier 14 comprenant unlogement 140 présentant undeuxième axe 141 ; - une première surface de
guidage 140a dans lelogement 140 ; - une deuxième surface de
guidage 14a dans lelogement 140 ; - une
première butée 140b dans le logement ; - une
deuxième butée 16b agencée sur lemobile 11 ;
- a mobile 11 comprising a first
functional portion 11a, a secondfunctional portion 11b and ashaft 15 for translation and / or rotation of the mobile 11, the shaft having afirst axis 151; - a
spring 13, in particular a helical spring. - a
housing 14 comprising ahousing 140 having asecond axis 141; - a
first guide surface 140a in thehousing 140; - a
second guide surface 14a in thehousing 140; - a
first stop 140b in the housing; - a
second stop 16b arranged on the mobile 11;
Dans le premier mode de réalisation, le mobile 11 présente une première partie fonctionnelle 11a qui comporte une roue 12. La roue est disposée à une première extrémité de l'arbre 15. Le mobile 11 présente encore une deuxième partie fonctionnelle 11 b. Ici, la deuxième partie fonctionnelle comprend une conformation 15b de l'arbre. Cette conformation se trouve à une deuxième extrémité de l'arbre 15. La conformation peut être bombée. Cette conformation peut être utilisée pour transmettre des efforts axiaux de déplacement du mobile selon l'axe 151 de l'arbre comme il sera vu plus loin.In the first embodiment, the mobile 11 has a first
Un tel mobile 11 est, par exemple, prévu au sein d'un dispositif d'embrayage, notamment prévu au sein d'un dispositif d'embrayage vertical, d'un mécanisme, en particulier d'un mécanisme de correction, d'une pièce d'horlogerie. Le mobile présente alors une première position axiale d'embrayage avec une chaîne cinématique et une deuxième position axiale où il n'est pas embrayé avec la chaîne cinématique. Ainsi, la première partie fonctionnelle peut être utilisée pour réaliser effectivement l'embrayage du mobile et la deuxième partie fonctionnelle peut être utilisée pour activer ou désactiver l'embrayage en déplaçant le mobile afin de positionner la première partie fonctionnelle de manière voulue.Such a mobile 11 is, for example, provided within a clutch device, in particular provided within a vertical clutch device, a mechanism, in particular a correction mechanism, a timepiece. The mobile then has a first axial clutch position with a kinematic chain and a second axial position where it is not engaged with the kinematic chain. Thus, the first functional part can be used to effectively effect the clutch of the mobile and the second functional part can be used to activate or deactivate the clutch by moving the mobile to position the first functional part in a desired manner.
L'arbre 15 peut ainsi être un arbre de rotation et/ou de translation du mobile, c'est-à-dire que le mobile est guidé en rotation et/ou en translation au niveau de l'arbre. Notamment, ce guidage peut n'être effectué qu'au niveau d'une portion de cet arbre.The
L'arbre 15 est par exemple cylindrique de révolution. La première partie fonctionnelle et/ou la deuxième partie fonctionnelle peuvent être venues de matière avec l'arbre. Ainsi, les ensembles :
- arbre, première partie fonctionnelle et deuxième partie fonctionnelle ; ou
- arbre et première partie fonctionnelle ; ou
- arbre et deuxième partie fonctionnelle ;
- tree, first functional part and second functional part; or
- tree and first functional part; or
- tree and second functional part;
Le logement 140 réalisé dans le boîtier comprend un premier alésage 140 et un deuxième alésage 14a. Les premier et deuxième alésages sont par exemple coaxiaux et/ou de révolution. Le premier alésage présente une première surface de guidage 140a. Cette première surface de guidage est par exemple simplement une portion du premier alésage 140. Le deuxième alésage présente une deuxième surface de guidage 14a. Cette deuxième surface de guidage est par exemple simplement tout ou portion du deuxième alésage. Chacune des première et deuxième surfaces de guidage sont agencées de sorte à coopérer directement ou indirectement avec une surface de l'arbre 15 pour réaliser la fonction de guidage. Le deuxième alésage présente un diamètre inférieur à celui du premier alésage. Ainsi, les premier et deuxième alésages sont raccordés par un épaulement 140b au fond du premier alésage. Le logement 140 permet également de recevoir le ressort 13.The
Le boîtier présente une surface externe 14c préférentiellement cylindrique de révolution. Cette surface peut être coaxiale à l'un et/ou à l'autre des premier et deuxième alésages. Ainsi, le boîtier peut par exemple être un bouchon.The housing has an
Le ressort 13 est ici du type hélicoïdal. Il est disposé entre la première butée et la deuxième butée, notamment contre les première et deuxième butées. Le ressort peut être précontraint entre la première et la deuxième butée. Alternativement, le ressort peut être monté non précontraint dans le boîtier. La précontrainte du ressort peut toutefois être réalisée lorsque le module est monté dans un système dont il est destiné à faire partie, comme une ébauche, une platine ou un pont. Dans ce cas, c'est un élément environnant le module horloger qui vient agir pour précontraindre le ressort. Dans le module horloger, le ressort assure dans tous les cas une fonction de rappel du mobile vers une position de repos, notamment une position axiale de repos.The
La première butée est constituée ou comprend l'épaulement 140b réalisé en fond d'alésage.The first stop is constituted or comprises the
La deuxième butée est réalisée sur l'arbre. Par exemple, elle peut être constituée ou réalisée par une bague 16 montée sur l'arbre. Cette bague peut notamment être chassée sur l'arbre. En particulier, elle peut être chassée jusqu'à venir en contact contre un épaulement réalisé sur l'arbre. Alternativement, la bague peut être fixée à l'arbre de toute autre manière. Dans le mode de réalisation représenté sur les
En alternative, la deuxième butée peut être constituée ou réalisée par une collerette formée sur l'arbre. Le ressort 13 est monté entre ces première et deuxième butées. Ainsi, le ressort 13 est encapsulé dans le boîtier.Alternatively, the second stop may be constituted or made by a flange formed on the shaft. The
La roue 12, l'arbre 15, et le ressort 13 sont ici délimités axialement vis-à-vis du bouchon 14 par le biais de la bague 16 rapportée sur l'arbre 15 au niveau d'une extrémité du mobile 11 opposée à celle de la roue 12. Le ressort 13 peut ainsi être maintenu en précontrainte, si bien que la portion 12b de la roue 12 peut naturellement être maintenue pressée à l'encontre d'une troisième butée 14b prévue sur le boîtier sous l'effet du ressort 13 comme représenté sur la
Comme vu précédemment, dans ce premier mode de réalisation, le mobile 11 présente une deuxième partie fonctionnelle 11 b située à une extrémité opposée à celle de la première partie fonctionnelle 11a. Cette deuxième partie fonctionnelle se présente sous la forme de l'extrémité 15b de l'arbre 15. Dans le cas de figure où le mobile 11 est, par exemple, prévu au sein d'un dispositif d'embrayage 111 comme représenté sur les
De manière avantageuse, la came de commande 112 peut éventuellement se présenter sous la forme d'une tige de commande de façon à mettre en oeuvre un mécanisme de réglage et/ou de remontage tel que celui décrit au sein de la demande de brevet
Bien entendu, la première partie fonctionnelle 11 a du mobile 11 peut comporter plus d'une roue. A titre d'exemple, la
Un deuxième mode de réalisation d'un module horloger 200 selon l'invention est décrit ci-après en référence aux
Dans les premier et deuxième modes de réalisation, les références des éléments identiques ou ayant la même fonction ne diffèrent que par leur premier chiffre : un « 1 » pour les éléments du premier mode et un « 2 » pour les éléments du deuxième mode.In the first and second embodiments, the references of identical elements or having the same function differs only in their first digit: a "1" for the elements of the first mode and a "2" for the elements of the second mode.
Avantageusement, le deuxième mode de réalisation présente les caractéristiques qui suivent.Advantageously, the second embodiment has the following characteristics.
Le module horloger 200 comprend un mobile 21 qui présente une première partie fonctionnelle 21a qui comporte une bascule 22, notamment une tirette 22 comme représenté sur la
La bague 26 permet aussi dans ce mode de réalisation de délimiter axialement la tirette 22 vis-à-vis du bouchon 24. Avantageusement, l'arbre 25 peut complémentairement ou alternativement être guidé au sein de la paroi intérieure 240a du logement 240 du bouchon 24 par le biais de la périphérie extérieure 26a de la bague 26. Ainsi, une surface 240a d'un premier alésage du logement coopère avec une surface 26a d'une bague 26 rapportée sur l'arbre de sorte à réaliser un guidage de l'arbre 25 dans le bouchon.The
Une telle réalisation permet de remplacer avantageusement une construction conventionnelle de tirette telle que celle divulguée au sein du document
Les
Le ressort 23 étant maintenu ici en précontrainte au sein du module horloger 200, la portion 22b de la tirette 22 tend naturellement à être pressée à l'encontre d'une portion 215b de la platine 215 sous l'effet du ressort 23 comme illustré sur la
Dans ce deuxième mode de réalisation, le mobile 21 présente une seconde partie fonctionnelle 21 b située à une extrémité opposée à celle de la première partie fonctionnelle 21 a. Celle-ci se présente sous la forme d'une découpe biseautée 25b de l'arbre 25, qui est prévue pour coopérer avec une pointe d'horloger représentée sous la forme d'une flèche sur la
Dans chacun des premier et deuxième modes de réalisation, la roue 12 et la tirette 22 présentent un degré de liberté en translation selon la direction de l'arbre 15, 25, par exemple une direction sensiblement perpendiculaire au plan du bâti du mouvement. Il est bien entendu possible de proposer un module horloger dans lequel un mobile présente un degré de liberté en translation selon une direction différente, par exemple une direction sensiblement parallèle au plan du bâti du mouvement.In each of the first and second embodiments, the
Un troisième mode de réalisation d'un module horloger 300 selon l'invention est décrit ci-après en référence aux
Dans les premier et troisième modes de réalisation, les références des éléments identiques ou ayant la même fonction ne diffèrent que par leur premier chiffre : un « 1 » pour les éléments du premier mode et un « 3 » pour les éléments du troisième mode.In the first and third embodiments, the references of the elements that are identical or have the same function differ only in their first number: a "1" for the elements of the first mode and a "3" for the elements of the third mode.
Avantageusement, le troisième mode de réalisation présente les caractéristiques qui suivent.Advantageously, the third embodiment has the following characteristics.
Dans ce troisième mode de réalisation, le module horloger 300 comprend un mobile 31 comportant, au niveau d'une première partie fonctionnelle 31 a, un pignon de remontoir 32 prévu pour être intégré au sein d'un dispositif d'embrayage 311 d'une chaîne de remontage d'un mécanisme 310.In this third embodiment, the
Le module 300 présente la particularité de comporter un pont 34 se présentant sous la forme d'un brancard qui est prévu pour être vissé sur une platine 315. Ainsi, dans ce troisième mode de réalisation, le boîtier est un pont.The
Outre la géométrie du boîtier 34, le mobile 31 présente une structure semblable à celle des mobiles 11 et 21. Dans ce troisième mode de réalisation, le pignon de remontoir 32 est positionné axialement par un ressort 33 qui est encapsulé au sein d'un logement 340 du pont 34. Le ressort 33 agit ici directement à l'encontre du pignon 32. Ce dernier est chassé sur un arbre 35 qui peut être prévu pour être pivoté au niveau de portions respectives 34a, 35a du pont et de l'arbre. Ainsi, les surfaces 34a et 35a coopèrent pour guider l'arbre dans le logement 340. Avantageusement, l'arbre 35 peut complémentairement ou alternativement être guidé au sein de la paroi intérieure 340a du logement 340 du pont 34 par le biais de la périphérie extérieure 32a du pignon 32. Ce dernier est également délimité axialement au niveau des portions respectives 34b, 32b du pont et de l'arbre, qui sont naturellement maintenues en contact sous l'effet du ressort 33.In addition to the geometry of the
Le mobile 31 comporte, en outre, une seconde partie fonctionnelle 31 b. Celle-ci se présente sous la forme d'une découpe axiale non circulaire 35b de l'arbre 35, qui est prévue pour coopérer avec un carré 312a d'une tige 312 du dispositif d'embrayage 311 lors de l'actionnement de la fonction de remontage du mouvement comme illustré sur la
Le ressort 33 permet ici de conférer un degré de liberté en translation au pignon 32 lors de l'entrée du carré 312a de la tige 312 au sein de la découpe 35b de l'arbre 35, et permet ainsi l'engrènement, sans risque de blocage, de la denture Breguet du pignon de remontoir 32 avec celle d'un second pignon de remontoir 313, simplement pivoté sur la tige de remontoir, qui est en prise avec une couronne 314 de remontage.The
Un quatrième mode de réalisation d'un module horloger 400 selon l'invention est décrit ci-après en référence aux
Dans les premier et quatrième modes de réalisation, les références des éléments identiques ou ayant la même fonction ne diffèrent que par leur premier chiffre : un « 1 » pour les éléments du premier mode et un « 4 » pour les éléments du quatrième mode.In the first and fourth embodiments, the references of identical elements or having the same function differs only by their first digit: a "1" for the elements of the first mode and a "4" for the elements of the fourth mode.
Avantageusement, le quatrième mode de réalisation présente les caractéristiques qui suivent.Advantageously, the fourth embodiment has the following characteristics.
Dans ce quatrième mode de réalisation, le module horloger 400 comprend plusieurs mobiles 41. Par exemple, les différents mobiles 41 présentent des roues 42, notamment des roues constituant des portions de chaînes cinématiques distinctes. Si le module horloger 400 comprend n mobiles, il s'ensuit qu'il comprend également n ressorts 43,n logements 440, n premières surfaces de guidage 44a, n deuxièmes surfaces de guidage 440a, n premières butées 440b dans le logement, n deuxièmes butées 46b, mais un seul boîtier 44. n est un entier naturel. Sur les
Dans le quatrième mode de réalisation, les roues 42 sont rapportées sur les arbres 45 et des collerettes 46 sont venues de matière avec les arbres 45.In the fourth embodiment, the
Dans le quatrième mode de réalisation décrit, toute les premières partie fonctionnelles présentent des roues 42 et assurent donc des fonctions identiques ou similaires. Alternativement, cela peut ne pas être le cas. Les différentes premières parties fonctionnelles peuvent assurer des fonctions différentes. Par exemple, une première partie fonctionnelle peut présenter une roue, une autre première partie fonctionnelle peut présenter une bascule ou un levier, une autre partie fonctionnelle peut présenter une came, un suiveur ou une tête de sautoir.In the fourth embodiment described, all the first functional parts have
Quel que soit le mode de réalisation, le mobile peut comprendre une partie fonctionnelle, comme une roue, qui est pivotée excentriquement relativement à l'axe de l'arbre et à l'axe de translation et/ou de rotation de l'arbre dans le boîtier.Whatever the embodiment, the mobile may comprise a functional part, such as a wheel, which is pivoted eccentrically relative to the axis of the shaft and to the axis of translation and / or rotation of the shaft in The box.
Quel que soit le mode de réalisation, le module horloger est prévu pour pallier les inconvénients des mobiles connus de l'art antérieur. Le module horloger se distingue notamment par le fait qu'il incorpore un ressort de rappel en son sein, ainsi que des moyens d'assemblage et de guidage. Cette réalisation s'avère particulièrement avantageuse en regard de sa simplicité de mise en oeuvre et d'assemblage au sein du mouvement. Ainsi, le module horloger se présente sous la forme d'un module préassemblé prêt à être rapporté au sein d'une ébauche d'un mouvement horloger. Une telle solution permet de minimiser l'encombrement d'un mécanisme horloger incorporant un tel mobile. Par ailleurs, le ressort de rappel peut être précontraint indépendamment de l'assemblage du mobile dans le mouvement. Son assemblage au sein du mouvement en est ainsi considérablement simplifié.Whatever the embodiment, the watch module is intended to overcome the disadvantages of the known mobile prior art. The watch module is distinguished in particular by the fact that it incorporates a return spring within it, as well as assembly and guiding means. This embodiment is particularly advantageous in view of its simplicity of implementation and assembly within the movement. Thus, the watch module is in the form of a preassembled module ready to be reported within a blank of a watch movement. Such a solution makes it possible to minimize the size of a clock mechanism incorporating such a mobile. Furthermore, the return spring can be prestressed independently of the assembly of the mobile in the movement. Its assembly within the movement is thus considerably simplified.
Quel que soit le mode de réalisation, le module horloger s'avère particulièrement avantageux en regard de sa simplicité de mise en oeuvre et d'assemblage au sein d'un mouvement d'horlogerie. Outre la présence d'un mobile ou d'un composant horloger 12, 22, 32, 42 qui est prévu pour actionner un second composant horloger d'un mécanisme 110, 210, 310, 410, le module se caractérise par des éléments de rappel 13, 23, 33, 43 encapsulés au sein d'un bouchon ou d'un pont 14, 24, 34, 44 qui est prévu pour être assemblé sur une ébauche 115, 215, 315, 415.Whatever the embodiment, the watch module is particularly advantageous in view of its simplicity of implementation and assembly within a watch movement. In addition to the presence of a mobile or a
Les mobiles 11, 21, 31, 41 présentent au moins un premier degré de liberté en translation dans une direction préférentiellement sensiblement perpendiculaire ou parallèle au plan du bâti du mouvement. Avantageusement, les mobiles 11, 21, 31, 41 présentent au moins un deuxième degré de liberté en rotation. Optionnellement, les mobiles présentent au moins une deuxième partie fonctionnelle 11 b, 21 b, 31 b, 41 b qui est prévue pour coopérer avec un mécanisme du mouvement horloger ou avec un outil lors des opérations de montage ou de démontage du mouvement horloger.The
Avantageusement, la course axiale du mobile 11, 21, 31, 41 est inférieure à l'étendue axiale du boîtier 14, 24, 34, 44. Avantageusement, les moyens de rappel se présentent sous la forme d'un ressort hélicoïdal 13, 23, 33, 43.Advantageously, the axial stroke of the mobile 11, 21, 31, 41 is less than the axial extent of the
Dans les différents modes de réalisation décrits, le module horloger comprend un mobile pivoté dans le boîtier. Toutefois, le module horloger peut alternativement comprendre un mobile uniquement en liaison glissière dans le boîtier. Ce pourrait notamment être le cas d'un mobile qui aurait une fonction de tête de sautoir ou de doigt, par exemple un doigt d'indexation en position ou un suiveur de came.In the various embodiments described, the watch module comprises a mobile pivoted in the housing. However, the watch module may alternatively comprise a mobile only in sliding connection in the housing. This could in particular be the case of a mobile that would have a function of jumping head or finger, for example an indexing finger in position or a cam follower.
L'invention porte encore sur un procédé de production d'un système horloger comprenant une platine ou un pont, notamment un mouvement horloger 110 ; 210 ; 310 ; 410 tel que décrit précédemment ou une pièce d'horlogerie 120 ; 220 ; 320 ; 420 telle que décrite précédemment.The invention also relates to a method for producing a watch system comprising a plate or a bridge, in particular a
