Definitions
- the present invention relates to a control mechanism for a timepiece comprising a member that can be operated manually from outside the timepiece, a rocker mounted to pivot between a rest position and a tilted position, and a spring arranged to return the rocker in the rest position, the rocker comprising a first arm arranged to cooperate with the manually operable member so as to allow the rocker to be brought into the tilted position when the member is actuated and comprising a second arm the end of which is arranged to come directly or indirectly into engagement with the toothing of a star wheel or a disc so as to allow it to be driven by actuating the control mechanism.
- Such mechanisms are known. They are most generally used as correctors making it possible to advance certain indicator members step by step in timepieces.
- One thinks in particular of calendar watches whose date, day of the week or even month indicators are very often either hands carried by stars, or discs.
- a calendar watch can for example be equipped with correctors making it possible to correct certain indicators individually without modifying the other time information displayed.
- the possibility of updating the indicators of a timepiece independently of each other can prove to be useful in particular when restarting a timepiece after several days of stoppage.
- the date indicators are incremented by the movement at regular intervals.
- the incrementation of the various indicators is often ensured by fingers which are each carried by a drive wheel and arranged to actuate the toothing of a star or of a disc at each turn of the driving wheel.
- date changes take place at midnight, and that it is therefore when the hands of a calendar watch are around midnight that the indicators are incremented by the calendar mechanism. This is the reason why the wearer of a calendar watch should absolutely not try to correct the indications of the calendar at this late hour.
- a calendar indicator which is carried by a star or a disc does not have the possibility of moving freely during the periods when the driving finger intersects the trajectory of the teeth of the star or the disc which it must drive. . It will thus be understood that, if, wishing to correct an indicator, a user decides to actuate the corresponding control mechanism during one of these periods, the antagonistic forces exerted by the driving finger and the manually actuable member risk causing the rupture of part of the mechanism.
- An object of the present invention is to remedy the drawbacks of the prior art which have just been explained.
- the present invention achieves this object as well than others by providing a timepiece operating mechanism which is in accordance with appended claim 1.
- the second arm is elastically flexible enough to allow the rocker to come into the tilted position when the mechanism is actuated, even if the end of the second arm is retained because the rotation of the star or of the disc is otherwise blocked. Thanks to this characteristic, a possible blocking of the star or of the disk does not prevent the first arm of the rocker from pivoting to the rockered position. It will also be understood that a blocking of the star or of the disc does not have any influence on the stroke of the manually operable member either. In other words, the same gesture performed by a user will drag the star or the disk by one step, when it is free to rotate, and will simply not drag it if it is blocked. Thanks to this characteristic, the force exerted by a user on the control mechanism does not risk causing the breakage of a part.
- the schematic plan views of the appended figures show a control mechanism according to an exemplary embodiment.
- the control mechanism represented comprises a control member that can be operated manually from outside the timepiece (symbolized by an arrow referenced 1), a rocker (generally referenced 3), and a return spring (referenced 9).
- the figures also show a star (referenced 11) which has seven teeth.
- the star could carry a member indicating the days of the week (not shown).
- the position of the star 11 is indexed by a jumper (referenced 13) which is biased against the toothing of the star by a jumper spring (referenced 15).
- the figures also show a drive wheel (referenced 17) forming part of a gear train (not shown) which is driven by a motor mechanism (not shown) of the timepiece.
- the gear train is arranged to rotate the drive wheel 17 at the speed of one revolution in 24 hours (clockwise in the drawings).
- drive wheel 17 carries a drive finger (referenced 19) which is arranged to cause star wheel 11 to pivot by the angular value of one tooth on each pass.
- Rocker 3 is pivotally mounted about an axis (reference 21), and it comprises two arms which extend diverging from the pivot axis.
- the first arm (referenced 5) is the thickest arm.
- it comprises a proximal part which is oriented substantially radially with respect to the pivot axis 21 of the rocker, and a distal part (referenced 25) which is pierced with an oblong opening (referenced 27) oriented tangentially with respect to the pivot axis 21.
- the second arm (reference 7), meanwhile, is thinner and ends in a beak (reference 23).
- the beak forms a bend of about 90° at the end of the second arm.
- the head of a screw protrudes of the oblong opening 27 made in the distal part 25 of the first arm.
- the oblong shape of the opening 27 gives the screw 29 the possibility of sliding inside the opening when the rocker 3 pivots around the axis 21, and on the other hand that the angular position of the rocker is always between a first extreme position in which the screw 29 abuts against one of the ends of the opening 27, and a second extreme position in which the screw abuts against the other end of the opening .
- the distal part 25 of the first arm 5 also carries a pin (not referenced) against which the end of the return spring 9 rests.
- Spring 9 is arranged to return rocker 3 to its first extreme position, called the rest position. It may be noted that, in the drawings, the direction in which the spring 9 recalls the rocker 3 corresponds to the counterclockwise direction.
- FIGS. 1A, 1B and 1C illustrate three successive stages in the normal operation of the control mechanism which is the subject of the present description.
- rocker 3 is in the rest position, while star 11 is indexed by jumper 13 which is lowered between two consecutive teeth of the star.
- the control mechanism is being actuated, and it can be seen that the rocker 3 is in an intermediate position in which the star 11 has been driven just enough so that one of its teeth has raised the jumper 13 It can be seen that at the moment represented, the jumper is balanced on the tip of the tooth.
- rocker 3 is in its second extreme position, called rocked position, whereas star wheel 11 has now advanced by the angular value of one tooth and jumper 13 is again lowered between two consecutive teeth.
- FIG. 2A illustrates by way of example such a deadlock situation.
- a tooth of the star 11 came to buttress against the end of the finger 19, so that the star is blocked before it can advance a full step counterclockwise. It can be seen that any rotation of Star 11 counter-clockwise is now impossible.
- the star 11 retains the beak 23 and therefore also the end of the second arm of the rocker 3.
- rocker 3 is not rigid since its second arm 7 is elastically flexible enough to allow the first arm 5 to come into the completely tilted position when the mechanism is activated, even if the spout 23 is retained because the star 11 is locked in rotation.
- the second arm 7 of the rocker can for example be essentially constituted by a leaf spring which connects the pivot axis 21 to the beak 23.
- the control mechanism is illustrated with the star 11 blocked by the drive finger 19 in a configuration identical to that of the figure 2A . Beak 23 has not moved either. However, the figure 2B shows the first arm 5 of the rocker 3 has pivoted clockwise to its second extreme position, called the tilted position.
- the screw 29 is in abutment against the corresponding end of the opening 27. It will be understood that it is the flexibility of the second arm 7 of the rocker which makes this configuration possible. We can indeed see that, in the figure 2B , the second arm 7 is curved while it is straight in the figure 2A . Thus, in accordance with the invention, when the actuation of the control mechanism does not allow the star wheel 11 to be driven by one step because the latter is blocked, the second arm 7 of the rocker has the possibility of flexing for allow the first arm 5 to come into the tilted position as if the mechanism had operated normally.
- the length of the stroke traveled by the first arm 5 of the rocker 3 is the same in the event of blocking as in normal operation, and that the same applies to the length of the stroke of the actuable member manually.
- the feeling of the user who actuates the control mechanism can thus also be the same.
- the second arm 7 must not be too flexible. Indeed, the second arm 7 of rocker 3 must have sufficient stiffness to allow it to push one of the teeth of the toothing of star 11 with sufficient force to overcome the holding torque generated by the pressure of the jumper 13 on the star teeth. It will be understood that the second arm of the rocker of a control mechanism according to the invention always fulfills this condition, provided that jumper spring 15 is not chosen too strong.

Description
La présente invention concerne un mécanisme de commande pour pièce d'horlogerie comprenant un organe actionnable manuellement depuis l'extérieur de la pièce d'horlogerie, une bascule montée pivotante entre une position de repos et une position basculée, et un ressort agencé pour rappeler la bascule en position de repos, la bascule comportant un premier bras agencé pour coopérer avec l'organe actionnable manuellement de façon à permettre d'amener la bascule en position basculée lorsque l'organe est actionné et comportant un deuxième bras dont l'extrémité est agencée pour venir directement ou indirectement en prise avec la denture d'une d'étoile ou d'un disque de façon à permettre de l'entraîner en actionnant le mécanisme de commande.The present invention relates to a control mechanism for a timepiece comprising a member that can be operated manually from outside the timepiece, a rocker mounted to pivot between a rest position and a tilted position, and a spring arranged to return the rocker in the rest position, the rocker comprising a first arm arranged to cooperate with the manually operable member so as to allow the rocker to be brought into the tilted position when the member is actuated and comprising a second arm the end of which is arranged to come directly or indirectly into engagement with the toothing of a star wheel or a disc so as to allow it to be driven by actuating the control mechanism.
De tels mécanismes sont connus. Ils servent le plus généralement de correcteurs permettant de faire avancer pas à pas certains organes indicateurs dans des pièces d'horlogerie. On pense notamment aux montres-calendrier dont les indicateurs du quantième, du jour de la semaine ou encore du mois, sont très souvent, soit des aiguilles portées par des étoiles, soit des disques. Une montre-calendrier peut par exemple être équipée de correcteurs permettant de corriger individuellement certains indicateurs sans modifier les autres informations horaires affichées. La possibilité de mettre à jour les indicateurs d'une pièce d'horlogerie indépendamment les uns des autres peut s'avérer utile notamment lors de la remise en marche d'une pièce d'horlogerie après plusieurs jours d'arrêt.Such mechanisms are known. They are most generally used as correctors making it possible to advance certain indicator members step by step in timepieces. One thinks in particular of calendar watches whose date, day of the week or even month indicators are very often either hands carried by stars, or discs. A calendar watch can for example be equipped with correctors making it possible to correct certain indicators individually without modifying the other time information displayed. The possibility of updating the indicators of a timepiece independently of each other can prove to be useful in particular when restarting a timepiece after several days of stoppage.
D"autre part, durant la marche normale d'une montre-calendrier, les indicateurs de dates sont incrémentés par le mouvement à intervalles réguliers. L'incrémentation des différents indicateurs est souvent assurée par des doigts qui sont portés chacun par une roue entraîneuse et agencés pour actionner la denture d'une étoile ou d'un disque à chaque tour de la roue entraîneuse. On gardera par ailleurs à l'esprit que les changements de date ont lieu à minuit, et que c'est donc lorsque les aiguilles d'une montre-calendrier se trouvent aux environs de minuit que les indicateurs sont incrémentés par le mécanisme de calendrier. C'est la raison pour laquelle le porteur d'une montre-calendrier ne doit absolument pas essayer de corriger les indications du calendrier à cette heure tardive. En effet, un indicateur de calendrier qui est porté par une étoile ou un disque n'a pas la possibilité de se déplacer librement durant les périodes où le doigt entraîneur coupe la trajectoire des dents de l'étoile ou du disque qu'il doit entraîner. On comprendra ainsi que, si, voulant corriger un indicateur, un utilisateur décide d'actionner le mécanisme de commande correspondant durant l'une de ces périodes, les forces antagonistes exercées par le doigt entraîneur et l'organe actionnable manuellement risquent de provoquer la rupture d'une partie du mécanisme.On the other hand, during the normal operation of a calendar watch, the date indicators are incremented by the movement at regular intervals. The incrementation of the various indicators is often ensured by fingers which are each carried by a drive wheel and arranged to actuate the toothing of a star or of a disc at each turn of the driving wheel. bear in mind that date changes take place at midnight, and that it is therefore when the hands of a calendar watch are around midnight that the indicators are incremented by the calendar mechanism. This is the reason why the wearer of a calendar watch should absolutely not try to correct the indications of the calendar at this late hour. Indeed, a calendar indicator which is carried by a star or a disc does not have the possibility of moving freely during the periods when the driving finger intersects the trajectory of the teeth of the star or the disc which it must drive. . It will thus be understood that, if, wishing to correct an indicator, a user decides to actuate the corresponding control mechanism during one of these periods, the antagonistic forces exerted by the driving finger and the manually actuable member risk causing the rupture of part of the mechanism.
Un certain nombre de solutions ont été proposées dans le but d'éviter tout problème lorsqu'on corrige manuellement les indications du calendrier aux « environ de minuit ». Il est notamment connu d'agencer le doigt que porte la roue entraîneuse de manière à ce qu'il soit libre de pivoter concentriquement à cette dernière, une goupille chassée dans la planche de la roue entraîneuse permettant alors d'entraîner le doigt. Avec un tel agencement, si on corrige manuellement une des indications du calendrier, alors que le doigt de la roue entraîneuse se trouve dans la trajectoire des dents de l'étoile ou du disque, les dents repoussent simplement le doigt dans la direction opposée à celle de la goupille. Il est donc possible de corriger les indications du calendrier vers l'avant sans risque de casse. Cette solution n'est pas non plus dénuée d'inconvénient. En particulier, elle entraîne le désindexage du doigt de la denture.A certain number of solutions have been proposed in order to avoid any problem when manually correcting the indications of the calendar at "about midnight". It is in particular known to arrange the finger carried by the drive wheel so that it is free to pivot concentrically to the latter, a pin driven into the board of the drive wheel then allowing the finger to be driven. With such an arrangement, if one of the indications of the calendar is manually corrected, while the finger of the driving wheel is in the trajectory of the teeth of the star or of the disc, the teeth simply push the finger back in the direction opposite to that of the pin. It is therefore possible to correct the indications of the calendar forwards without risk of breakage. This solution is not without drawbacks either. In particular, it leads to the de-indexing of the finger from the teeth.
Un but de la présente invention est de remédier aux inconvénients de l'art antérieur qui viennent d'être expliqués. La présente invention atteint ce but ainsi que d'autres en fournissant un mécanisme de commande pour pièce d'horlogerie qui est conforme à la revendication 1 annexée.An object of the present invention is to remedy the drawbacks of the prior art which have just been explained. The present invention achieves this object as well than others by providing a timepiece operating mechanism which is in accordance with appended
Conformément à l'invention, le deuxième bras est suffisamment flexible élastiquement pour permettre à la bascule de venir en position basculée quand le mécanisme est actionné, même si l'extrémité du deuxième bras est retenue parce que la rotation de l'étoile ou du disque est bloquée par ailleurs. Grâce à cette caractéristique, un éventuel blocage de l'étoile ou du disque n'empêche pas le premier bras de la bascule de pivoter jusqu'à la position basculée. On comprendra en outre qu'un blocage de l'étoile ou du disque n'a pas non plus d'influence sur la course de l'organe actionnable manuellement. Autrement dit, le même geste effectué par un utilisateur va entraîner d'un pas l'étoile ou le disque, lorsqu'il est libre de tourner, et ne va tout simplement pas l'entraîner s'il est bloqué. Grâce à cette caractéristique, la force exercée par un utilisateur sur le mécanisme de commande ne risque pas de provoquer la rupture d'une pièce.According to the invention, the second arm is elastically flexible enough to allow the rocker to come into the tilted position when the mechanism is actuated, even if the end of the second arm is retained because the rotation of the star or of the disc is otherwise blocked. Thanks to this characteristic, a possible blocking of the star or of the disk does not prevent the first arm of the rocker from pivoting to the rockered position. It will also be understood that a blocking of the star or of the disc does not have any influence on the stroke of the manually operable member either. In other words, the same gesture performed by a user will drag the star or the disk by one step, when it is free to rotate, and will simply not drag it if it is blocked. Thanks to this characteristic, the force exerted by a user on the control mechanism does not risk causing the breakage of a part.
D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple non limitatif, et faite en référence aux dessins annexés dans lesquels :
- les
figures 1A, 1B et 1C sont des vues en plan schématisées qui illustrent trois stades successifs dans le fonctionnement normal d'un mécanisme de commande qui est conforme à un mode de réalisation particulier de l'invention ; - les
figures 2A, et 2B sont des vues semblables à celles de lafigure 1 illustrant deux instants successifs dans le fonctionnement du même mécanisme de commande lorsque la rotation de l'étoile est bloquée par un doigt entraîneur.
- the
figures 1A, 1B and 1C are diagrammatic plan views which illustrate three successive stages in the normal operation of a control mechanism which is in accordance with a particular embodiment of the invention; - the
figures 2A, and 2B are views similar to those of thefigure 1 illustrating two successive instants in the operation of the same control mechanism when the rotation of the star is blocked by a drive finger.
Les vues schématiques en plan des figures annexées montrent un mécanisme de commande conforme à un mode de réalisation exemplaire. Le mécanisme de commande représenté comprend un organe de commande actionnable manuellement depuis l'extérieur de la pièce d'horlogerie (symbolisé par une flèche référencée 1), une bascule (généralement référencée 3), et un ressort de rappel (référencé 9). Outre le mécanisme de commande, les figures montrent encore une étoile (référencée 11) qui comporte sept dents. Dans le présent exemple, l'étoile pourrait porter un organe indicateur des jours de la semaine (non représenté). La position de l'étoile 11 est indexée par un sautoir (référencé 13) qui est rappelé contre la denture de l'étoile par un ressort de sautoir (référencé 15). Les figures montrent en outre une roue entraîneuse (référencée 17) faisant partie d'un rouage (non représenté) qui est entraîné par un mécanisme moteur (non représenté) de la pièce d'horlogerie. Dans l'exemple illustré, le rouage est agencé pour faire tourner la roue entraîneuse 17 à la vitesse d'un tour en 24 heures (dans le sens horaire sur les dessins). On peut voir que la roue entraîneuse 17 porte un doigt entraîneur (référencé 19) qui est agencé pour faire pivoter l'étoile 11 de la valeur angulaire d'une dent à chaque passage.The schematic plan views of the appended figures show a control mechanism according to an exemplary embodiment. The control mechanism represented comprises a control member that can be operated manually from outside the timepiece (symbolized by an arrow referenced 1), a rocker (generally referenced 3), and a return spring (referenced 9). In addition to the control mechanism, the figures also show a star (referenced 11) which has seven teeth. In the present example, the star could carry a member indicating the days of the week (not shown). The position of the
La bascule 3 est montée pivotante autour d'un axe (référencé 21), et elle comprend deux bras qui s'étendent en divergeant à partir de l'axe de pivotement. On peut voir que le premier bras (référencé 5) est le bras le plus épais. Dans l'exemple illustré, il comprend une partie proximale qui est orientée sensiblement radialement par rapport à l'axe de pivotement 21 de la bascule, et une partie distale (référencée 25) qui est percée d'une ouverture oblongue (référencée 27) orientée tangentiellement par rapport à l'axe de pivotement 21. On peut voir que ces caractéristiques donnent au premier bras 5 la forme approximative d'un T. Le deuxième bras (référencé 7), quant à lui, est plus fin et se termine par un bec (référencé 23). On peut voir que le bec forme un coude d'environ 90° à l'extrémité du deuxième bras. Dans l'exemple illustré, la tête d'une vis (référencée 29) dépasse de l'ouverture oblongue 27 ménagée dans la partie distale 25 du premier bras. On peut comprendre d'une part que la forme oblongue de l'ouverture 27 donne à la vis 29 la possibilité de coulisser à l'intérieur de l'ouverture lorsque la bascule 3 pivote autour de l'axe 21, et d'autre part que la position angulaire de la bascule est toujours comprise entre une première position extrême dans laquelle la vis 29 bute contre une des extrémités de l'ouverture 27, et une seconde position extrême dans laquelle la vis bute contre l'autre extrémité de l'ouverture. La partie distale 25 du premier bras 5 porte également une goupille (non référencée) contre laquelle l'extrémité du ressort de rappel 9 se trouve en appui. Le ressort 9 est agencé pour rappeler la bascule 3 vers sa première position extrême, dite position de repos. On peut noter que, dans les dessins, le sens dans lequel le ressort 9 rappelle la bascule 3 correspond au sens antihoraire.

Comme déjà mentionné, si le mécanisme de commande est actionné à un moment où l'étoile 11 ne peut pas se déplacer librement, la force exercée par l'utilisateur sur l'organe actionnable manuellement risque de provoquer la rupture d'une partie du mécanisme. La
Conformément à l'invention, la bascule 3 n'est pas rigide puisque son deuxième bras 7 est suffisamment flexible élastiquement pour permettre au premier bras 5 de venir en position complètement basculée quand le mécanisme est actionné, même si le bec 23 est retenu parce que l'étoile 11 est bloquée en rotation. Le deuxième bras 7 de la bascule peut par exemple être essentiellement constitué par une lame-ressort qui relie l'axe de pivotement 21 au bec 23. En se référant maintenant à la
Enfin, lorsque le mécanisme de commande se trouve dans la configuration illustrée dans la
Il vaut la peine de noter encore que le deuxième bras 7 ne doit pas être trop souple. En effet, il faut que le deuxième bras 7 de la bascule 3 ait une raideur suffisante pour lui permettre de pousser une des dents de la denture de l'étoile 11 avec suffisamment de force pour vaincre le couple de maintien engendré par la pression du sautoir 13 sur la denture de l'étoile. On comprendra que le deuxième bras de la bascule d'un mécanisme de commande selon l'invention remplit toujours cette condition, pour autant que le ressort de sautoir 15 ne soit pas choisi trop fort.It is worth noting again that the
On comprendra en outre que diverses modifications et/ou améliorations évidentes pour un homme du métier peuvent être apportées aux modes de réalisation qui font l'objet de la présente description sans sortir du cadre de la présente invention définie par les revendications annexées.It will also be understood that various modifications and/or improvements obvious to a person skilled in the art can be made to the embodiments which are the subject of the present description without departing from the scope of the present invention defined by the appended claims.
