Description

Domaine de l'inventionField of the invention

L'invention concerne un mécanisme d'affichage sonore, comportant un mécanisme de chronographe combiné à un mécanisme de sonnerie, agencé pour l'affichage sonore, par ledit mécanisme de sonnerie, d'une durée mesurée par ledit mécanisme de chronographe.The invention relates to a sound display mechanism, comprising a chronograph mechanism combined with a striking mechanism, arranged for the sound display, by said striking mechanism, of a duration measured by said chronograph mechanism.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant un tel mécanisme d'affichage sonore.The invention also relates to a timepiece, including a watch, comprising such a sound display mechanism.

L'invention concerne le domaine des mécanismes d'affichage d'horlogerie.The invention relates to the field of clock display mechanisms.

Arrière-plan de l'inventionBackground of the invention

Certains affichages de pièces d'horlogerie sont parfois difficiles à lire, en particulier quand la pièce d'horlogerie est une montre de petites dimensions, comme une montre dame, ou encore une montre compliquée, comportant un grand nombre d'affichages, chacun occupant alors une surface nécessairement restreinte, ou venant en superposition d'autres afficheurs, ce qui peut rendre l'interprétation imprécise pour l'utilisateur, ce qui est paradoxal quand il s'agit d'une mesure de précision du temps.Some displays of timepieces are sometimes difficult to read, especially when the timepiece is a small watch, such as a lady's watch, or a complicated watch, with a large number of displays, each occupying then a necessarily restricted area, or superimposed other displays, which can make the interpretation imprecise for the user, which is paradoxical when it comes to a measure of accuracy of time.

La lecture d'un affichage peut encore être perturbée par une faible luminosité ambiante comme en plongée, ou dans certaines plages horaires de nuit ou de crépuscule, ou au contraire être perturbée par des éclairages parasites générateurs d'ombres rendant les indications illisibles, ou encore en raison d'une déficience visuelle de l'utilisateur ou de conditions particulières d'emploi, comme le vol de nuit ou certaines opérations particulières. C'est d'ailleurs la raison pour laquelle les horlogers du XVIIIème et du XIXème siècle ont développé les montres à sonnerie, au passage ou à répétition, ou encore les montres à tact permettant d'avoir une information tactile.The reading of a display can still be disturbed by low ambient light such as diving, or in certain time slots night or twilight, or conversely be disturbed by parasitic lighting shadows making the indications illegible, or because of a visual impairment of the user or special conditions of employment, such as night flying or certain special operations. This is the reason why watchmakers of the eighteenth and nineteenth century have developed watches ringing, passage or repetition, or the tactful watches for having a tactile information.

La demande EP17206439.6 du même déposant décrit un mécanise de chronographe lié à mécanisme de sonnerie externe ou interne pour effectuer, en particulier à la demande, un affichage sonore d'une durée mesurée par le mécanisme de chronographe, ce mécanisme constitue une répétition chronographe. Quand le mécanisme de sonnerie est en marche, les râteaux de secondes et dizaines de secondes ainsi le palpeur des minutes peuvent se trouver dans la course des cames de secondes, dizaines de secondes et minutes. Si on venait à enclencher le mécanisme de chronographe (START), on risquerait d'arrêter le mouvement, avec un fort risque de casse. C'est pourquoi il est nécessaire d'empêcher qu'on puisse enclencher le mécanisme de chronographe pendant que le mécanisme de sonnerie est en marche.The demand EP17206439.6 the same depositor describes a chronograph mechanism linked to external or internal striking mechanism to perform, in particular on demand, a sound display of a duration measured by the chronograph mechanism, this mechanism is a chronograph repeat. When the striking mechanism is running, the rakes of seconds and tens of seconds so the minute feeler can be in the run of the seconds cams, tens of seconds and minutes. If we just started the chronograph mechanism (START), one could stop the movement, with a high risk of breakage. Therefore, it is necessary to prevent the chronograph mechanism from being engaged while the striking mechanism is operating.

Résumé de l'inventionSummary of the invention

L'invention se propose d'apporter une sécurité de fonctionnement à un mécanisme de répétition chronographe, couplant à un affichage visuel classique un affichage sonore, ou remplaçant un affichage visuel classique par un affichage sonore, pour prévenir tout enclenchement du mécanisme de chronographe pendant que le mécanisme de sonnerie fonctionne.The invention proposes to provide operational reliability to a chronograph repetition mechanism, coupling to a conventional visual display a sound display, or replacing a conventional visual display by a sound display, to prevent any engagement of the chronograph mechanism while the striking mechanism works.

A cet effet, l'invention concerne un mécanisme de répétition chronographe d'horlogerie selon la revendication 1.For this purpose, the invention relates to a clock chronograph repetition mechanism according to claim 1.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant un tel mécanisme de répétition chronographe.The invention also relates to a timepiece, including a watch, including such a chronograph repeat mechanism.

Ce mécanisme d'affichage sonore 500 d'horlogerie à répétition chronographe permet l'affichage sonore, par un mécanisme de sonnerie 1, d'une durée mesurée par un mécanisme de chronographe 100.This chronograph repetition clock sound display mechanism 500 allows the audible display, by a striking mechanism 1, of a duration measured by a chronograph mechanism 100.

Selon l'invention, ce mécanisme de sonnerie 1 comporte une commande d'armage 39, qui est agencée pour déclencher la lecture de la durée chronométrée sur les limaçons et cames, et pour entraîner une crémaillère 33 à l'encontre de moyens de rappel élastique constituant des moyens moteurs du mécanisme de sonnerie 1, pour mouvoir un bloc de sonnerie comportant un pignon de crémaillère 31 solidaire d'un rochet de sonnerie 32, et pour mouvoir une pièce de sonnerie pour chaque came d'affichage pour la lecture de la grandeur concernée, par exemple pièce des minutes sur une came-limaçon des minutes, pièce des secondes sur une came-limaçon des secondes, pièce des dizaines de secondes sur une came des dizaines de secondes, ou similaire, et déclencher une sonnerie correspondante.According to the invention, this striking mechanism 1 comprises an armature control 39, which is arranged to trigger the reading of the timed duration on the snails and cams, and to drive a rack 33 against elastic return means constituting driving means of the striking mechanism 1, for moving a ringing unit comprising a rack pinion 31 integral with a ringing ratchet 32, and for moving a ringing part for each display cam for reading the quantity concerned, for example minute piece on a cam-snail minutes, seconds piece on a cam-snail seconds, tens of seconds piece on a cam tens of seconds, or the like, and trigger a corresponding ring.

Selon l'invention, ce mécanisme d'affichage sonore 500 comporte, entre le mécanisme de commande du mécanisme de chronographe 100 et la commande d'armage 39, un mécanisme de sécurité 40, qui est agencé pour, selon la position du mobile de sonnerie, et plus particulièrement mais non limitativement du pignon de crémaillère 31, autoriser ou non la course d'une commande 56, que comporte le mécanisme de commande du mécanisme de chronographe 100, et laquelle est agencée pour être pivotée sous l'action d'un poussoir de départ de chronographe 562.According to the invention, this sound display mechanism 500 comprises, between the control mechanism of the chronograph mechanism 100 and the armature control 39, a safety mechanism 40, which is arranged for, depending on the position of the ringing device. , and more particularly but not limited to the rack pinion 31, allow or not the stroke of a control 56, which includes the control mechanism of the chronograph mechanism 100, and which is arranged to be pivoted under the action of a 562 chronograph start pushbutton.

Le mécanisme de chronographe 100 comporte classiquement des moyens de commande externes accessibles à l'utilisateur, tel que poussoir départ-arrêt, poussoir de retour à zéro, ou similaires, et notamment tels que décrits dans l'ouvrage l'ouvrage collectif « Théorie d'horlogerie » de MM. Reymondin, Monnier, Jeanneret, Pelaratti, édité par la FET (Fédération des écoles techniques) en Suisse, au chapitre 11. Pour la fonction départ-arrêt, ces moyens de commande externes entraînent en général une commande 56, qui tire ou pousse une came de commande 60, notamment une came pivotante, telle qu'une roue à colonnes 54, ou une came comportant une navette supérieure et une navette inférieure, ou autre.The chronograph mechanism 100 conventionally comprises external control means accessible to the user, such as push-stop, push back to zero, or the like, and in particular as described in the book the collective work "Theory of watchmaking of MM. Reymondin, Monnier, Jeanneret, Pelaratti, published by the FET (Federation of Technical Schools) in Switzerland, chapter 11. For the start-stop function, these external control means generally cause a command 56, which pulls or pushes a cam control device 60, in particular a pivoting cam, such as a column wheel 54, or a cam having an upper shuttle and a lower shuttle, or the like.

L'invention est applicable aussi bien à un chronographe mono-poussoir tel qu'illustré par les figures, utilisable pour déclencher les commandes de départ START, arrêt STOP, et remise à zéro RAZ, qu'à un mécanisme de chronographe à deux poussoirs, l'un pour marche-arrêt, l'autre pour la remise à zéro, selon la même logique, qui consiste à mouvoir, lors de l'actionnement manuel du mécanisme de sonnerie, un mécanisme d'isolement, comportant une bascule de sécurité exposée ci-après, agencée pour rendre impossible tout appui sur le poussoir unique, ou sur l'un quelconque des poussoirs, selon le cas, par interposition d'un plot sous chaque poussoir concerné.The invention is applicable both to a single-pusher chronograph as illustrated by the figures, usable to trigger the start commands START, stop STOP, and reset reset, that a chronograph mechanism with two pushers, one for on-off, the other for resetting, according to the same logic, which consists in moving, during the manual actuation of the striking mechanism, an isolation mechanism, comprising an exposed safety scale Hereinafter, arranged to make it impossible to press the single pusher, or any of the pushers, as the case may be, by interposing a pad under each pusher concerned.

Plus particulièrement, le mécanisme de commande du mécanisme de chronographe 100 comporte un poussoir de départ de chronographe 562, agencé pour exercer un appui sur la commande 56, soumise au rappel d'un ressort de commande 58, et qui est une bascule qui pivote autour d'un axe de commande F. Dans la réalisation non limitative illustrée, cette commande 56 est munie d'un crochet 57, agencée pour manoeuvrer le rochet 59 d'une came de commande 60, telle que roue à colonnes 54 dans la variante non limitative illustrée par les figures, ou came de commande, ou autre, laquelle came de commande 60 est maintenue en position par un sautoir 55, ou similaire. Le mécanisme de chronographe 100 comporte au moins un mobile d'affichage rotatif, tel que mobile des secondes ou mobile des minutes, qui est solidaire au moins en rotation d'une came d'affichage correspondante, dont le pourtour coopère avec le palpeur d'une pièce de sonnerie correspondante, que comporte le mécanisme de sonnerie 1, pour sonner une valeur numérique caractéristique d'une durée chronométrée mesurée par le mécanisme de chronographe 100.More particularly, the control mechanism of the chronograph mechanism 100 comprises a chronograph start pusher 562, arranged to exert a bearing on the control 56, subject to the recall of a control spring 58, and which is a rocker that pivots around of a control pin F. In the illustrated non-limiting embodiment, this control 56 is provided with a hook 57, arranged to manipulate the ratchet 59 of a control cam 60, such as a column wheel 54 in the variant limitative illustrated by the figures, or control cam, or other, which control cam 60 is maintained in position by a jumper 55, or the like. The chronograph mechanism 100 comprises at least one mobile rotary display, such as mobile seconds or mobile minutes, which is integral at least in rotation with a corresponding display cam, the periphery cooperates with the probe of a corresponding ringing part, which comprises the striking mechanism 1, to ring a numerical value characteristic of a timed duration measured by the chronograph mechanism 100.

Le mécanisme de sécurité 40 est agencé pour, selon la position du mobile de sonnerie, et plus particulièrement mais non limitativement du pignon de crémaillère 31, autoriser ou non la course de la commande 56. A cet effet, dans la variante illustrée par les figures, cette liaison mécanique de sécurité comporte une bascule de sécurité 41 montée pivotante sur un axe de sécurité E. Une première extrémité 44 de la bascule de sécurité 41 coopère en appui avec une came 310 à deux niveaux, inférieur 311 et supérieur 312, qui est solidaire du pignon de crémaillère 31, sous l'action d'un moyen de rappel élastique, notamment d'un ressort de sécurité 45. La deuxième extrémité 42 de cette bascule de sécurité 41 comporte un plot 43, qui est agencé pour s'interposer sur la trajectoire de la commande 56, selon la position angulaire de la bascule de sécurité 41 :

  • quand la sonnerie fonctionne, tel que visible sur les figures 2 et 4, le plot 43 s'oppose au pivotement de la commande 56 sous une pression effectuée par un utilisateur sur le poussoir de départ de chronographe 562 ;
  • quand la sonnerie ne fonctionne pas ou plus, tel que visible sur les figures 1, 3, et 4, le plot 43 ne s'oppose pas au pivotement de la commande 56 sous une pression effectuée par un utilisateur sur le poussoir de départ de chronographe 562, la figure 5 montre la position enfoncée du poussoir de départ de chronographe 562.
The safety mechanism 40 is arranged for, depending on the position of the striking wheel, and more particularly but not limited to the rack pinion 31, allow or not the stroke of the control 56. For this purpose, in the variant illustrated by the figures , this mechanical safety connection comprises a safety latch 41 pivotally mounted on a safety axis E. A first end 44 of the security latch 41 cooperates in abutment with a cam 310 at two levels, lower 311 and upper 312, which is secured to the rack pinion 31, under the action of an elastic return means, in particular a safety spring 45. The second end 42 of this safety latch 41 comprises a stud 43, which is arranged to interpose on the trajectory of the control 56, according to the angular position of the security latch 41:
  • when the ring is working, as visible on the figures 2 and 4 , the stud 43 opposes the pivoting of the control 56 under a pressure made by a user on the chronograph start pushbutton 562;
  • when the ring does not work or more, as visible on the figures 1 , 3, and 4 , the stud 43 does not oppose the pivoting of the control 56 under a pressure made by a user on the chronograph start pushbutton 562, the figure 5 shows the depressed position of the 562 chronograph start pushbutton.

On comprend que cette configuration permet de prévenir tout risque d'arrêt du mouvement ou de casse : l''utilisateur ne peut enclencher le mécanisme de chronographe 100 que quand il en a le droit, c'est-à-dire quand le mécanisme de sonnerie 1 est inopérant.It is understood that this configuration prevents any risk of stopping the movement or breakage: the user can not engage the chronograph mechanism 100 when it has the right, that is to say when the mechanism of ring 1 is inoperative.

L'invention peut mettre en oeuvre un mécanisme de sonnerie plus complexe que ceux exposés dans l'ouvrage cité en référence, notamment avec plusieurs sonneries ou mélodies comme sur les demandes de brevets au nom de la Société BLANCPAIN : sonnerie classique ou un jeu de mélodie, mécanisme de sonnerie à plusieurs étages avec des pièces à râteaux différents.The invention can implement a ringing mechanism more complex than those set forth in the referenced work, especially with several ringtones or melodies as on the patent applications on behalf of the BLANCPAIN Company: classical ringtone or a melody game , multi-stage bell mechanism with different rake pieces.

L'invention concerne encore une pièce d'horlogerie 1000, notamment une montre, comportant un tel mécanisme d'affichage 500.The invention also relates to a timepiece 1000, in particular a watch, comprising such a display mechanism 500.

Dans un mode de réalisation, le mécanisme de sonnerie 1 est distinct du mécanisme d'affichage 500.In one embodiment, the striking mechanism 1 is distinct from the display mechanism 500.

Dans un autre mode de réalisation, le mécanisme de sonnerie 1 est intégré audit mécanisme d'affichage 500.In another embodiment, the striking mechanism 1 is integrated with said display mechanism 500.

Si le mécanisme d'affichage sonore décrit ci-dessus est conçu comme un doublage d'un affichage visuel classique, il peut également se substituer à ce dernier.If the sound display mechanism described above is designed as a dubbing of a conventional visual display, it can also be substituted for the latter.

L'invention permet d'ajouter une sécurité utile à un mécanisme d'affichage de type répétition chronographe, qui combine un mécanisme de chronographe et un mécanisme de sonnerie, qui sont connus pour être les mécanismes horlogers les plus complexes et les plus délicats, et qu'il est nécessaire de protéger contre toute manoeuvre dangereuse.The invention makes it possible to add a useful security to a chronograph-type display mechanism, which combines a chronograph mechanism and a striking mechanism, which are known to be the most complex and delicate watchmaking mechanisms, and that it is necessary to protect against any dangerous maneuver.
