- the ring 62 has four teeth 60 regularly distributed. Thus, each time the drum is released, it performs a quarter turn. When it is desired that this rotation of the drum takes place at a high speed, the barrel spring 5 then being calibrated in a suitable manner, the shock resulting from the locking of the ring 62 by the cooperation between the spout 58 and a tooth 60 can be violent. Thus, mounting the first latch 10 on the frame via a damper limits the risk of premature wear constituents of the watch movement according to the present invention.

- the disengaging member 68 comprises a toothed pinion 70 integral with a cam 72, of oblong shape and arranged eccentrically with reference to the axis of rotation of the pinion gear.
- the latter is dimensioned and toothed so that it turns on itself when the barrel 4 is a quarter turn.
- the fingers release the two latches 10 and 50 during the rotation of the drum 4, even when the pusher 24 is held down by the user, guaranteeing in all cases the locking of the drum barrel after a predefined stroke, a quarter of a turn in the embodiment shown in a non-limiting manner.
- the drum When the drum is released, it also drives a first transmission mobile 74 kinematically connected to a mobile, preferably display or contributing to the appearance of the room.
- the figure 4 represents a simplified perspective view of a preferred embodiment of a watch mechanism that can be driven from the barrel drum whose behavior has just been described.
- the first transmission mobile 74 is arranged in engagement with a second transmission mobile 76, itself engaged with a pinion 78 integral with the transmission shaft 2.
- the corresponding timepiece comprises a mobile dial having at least one window or window that can take four different angular positions, with reference to the timepiece box , in order to provide four different appearances to the room and / or present different complications of which only one would be visible at a time.
- a stabilizing member 86 may be provided, which comprises a roller 88 carried by the end of a spring 90.
- the roller 88 is arranged to cooperate with a recess 92 formed in the ring 82 to each of the stable positions provided for the mobile dial.

- the energy stored in the barrel is sufficient to allow several successive activations of the dial between two pumping. It may be preferable to provide that the safety device prevents the user from unlocking the barrel drum if the residual energy of its spring is no longer sufficient to guarantee its movement a quarter of a turn, which could lead to a phase shift of the mobile dial.
- the safety device comprises a differential gear 100, of which a first input wheel 101 has a kinematic connection with the winding ratchet 6 of the barrel, and a second input wheel 102 meshes directly with the drum 4 of the barrel.
- barrel 1 The first wheel 101 is connected to the winding ratchet 6 via a reference 104 for rotating the first input wheel 101 in the direction required to ensure the proper operation of the differential gear.

- the finger 114 is intended to engage between two branches 122 of the second counting mobile 116 to drive the latter in rotation, in one direction or the other.
- the toothing of the second counting mobile 116 is arranged in engagement with a rack (numerical reference 124 on the figure 1 ) to ensure the displacement of the locking wheel 118, either towards the first pusher 14 or towards the second pusher 24.
- the locking mobile 118 carries first and second arms 126, 128 for cooperating respectively with the first and second pushers 14, 24 to ensure locking.
- an action on the first pusher 14 has the effect of raising the spring 5 of the cylinder 1
- an action on the second pusher 24 has the effect of releasing the drum 4 of the cylinder and thus at least partially unload the spring 5.
- cam 112 also defines a stop for the first counting mobile 110 via the finger 114.
- the user wishes to turn the mobile support 84 by a quarter of a turn, he actuates the second pusher 24. In doing so, he releases the drum 4 which rotates a quarter of a turn and causes the rotating the second input wheel 102 of the differential gear 100.
- the rotation of the second wheel 102 causes a rotation of the first counting wheel 110 in the anti-clockwise direction of rotation.
- the angle of rotation of the first counting mobile 110 is a function of the gear ratio introduced in particular by the gear train 108.
- the first pusher 14 can again be operated once to raise the mainspring before being locked again.
- the second pusher 24 can still be actuated several times before being locked by the second arm 128 of the locking wheel 118. More specifically, in the example illustrated here by way of non-limiting example, the second pusher 24 can still be operated three times before being locked.
- the spring 5 may be calibrated in such a way that it makes it possible to actuate the support mobile 84 84 times.

More particularly, this construction makes it possible to guarantee a good positioning of the arms in their locking position. Indeed, when the locking wheel is placed in one or other of the locking positions, the pusher 14 or 24 corresponding is still actuated and is in the path of its locking arm 126 or 128. In this intermediate phase, the arm pivots by deforming its spring 130 to that the pusher is released and allows the arm to be positioned in its locking position, under the effect of the spring.

Description
La présente invention concerne un dispositif d'entraînement d'un mécanisme pour mouvement horloger, comprenant au moins un mobile et un dispositif de commande destinés à actionner le mécanisme, et comportant un levier agencé pour agir sur un premier verrou susceptible d'être déplacé entre des première et seconde positions respectives, en réponse à une action prédéfinie d'un utilisateur et par l'intermédiaire d'un organe d'actionnement mobile entre des positions active et inactive, pour au moins indirectement verrouiller et libérer le mobile. Le levier comprend une base susceptible de se déplacer en référence au bâti du mouvement horloger en réponse à cette action prédéfinie. Le dispositif d'entraînement comprend également un premier organe élastique agencé pour tendre à positionner le premier verrou dans sa première position, ainsi qu'un organe de débrayage agencé pour être mis en mouvement par les déplacements du mobile et destiné à permettre le déplacement du verrou vers sa première position pour verrouiller le mobile.The present invention relates to a device for driving a mechanism for a watch movement, comprising at least one mobile and a control device intended to actuate the mechanism, and comprising a lever arranged to act on a first lock that can be moved between respective first and second positions, in response to a predefined action of a user and via a movable actuator between active and inactive positions, to at least indirectly lock and release the mobile. The lever includes a base capable of moving with reference to the frame of the watch movement in response to this predefined action. The drive device also comprises a first elastic member arranged to tend to position the first lock in its first position, and a release member arranged to be set in motion by the movements of the mobile and intended to allow the movement of the lock. to its first position to lock the mobile.
De nombreux dispositifs de ce type ont déjà été divulgués. On pourra noter, par exemple, la structure d'un dispositif de commande mis en oeuvre en relation avec un mécanisme de chronographe, tel que décrit dans la demande de brevet
Ce mécanisme de chronographe comporte un marteau de remise à zéro des compteurs de secondes et de minutes chronométrées. Un organe élastique est prévu pour exercer une pression sur le marteau tendant à le positionner dans sa position active, dans laquelle il verrouille les compteurs de secondes et de minutes chronométrées. Le marteau porte un bec agencé pour coopérer avec les colonnes d'une roue à colonnes, permettant de soulever le marteau pour libérer les compteurs de secondes et de minutes et effectuer la mesure d'un intervalle de temps. Un levier dont les déplacements sont commandés à partir d'un organe de commande externe est agencé pour faire tourner la roue à colonnes et, notamment, pour libérer le marteau ou le soulever.This chronograph mechanism includes a reset hammer of the seconds and minutes timed counters. An elastic member is provided to exert a pressure on the hammer tending to position it in its active position, in which it locks the timed seconds and minutes counters. The hammer carries a spout arranged to cooperate with the columns of a column wheel, to raise the hammer to release the seconds and minutes counters and measure a time interval. A lever whose movements are controlled from an organ of external control is arranged to rotate the column wheel and, in particular, to release the hammer or lift.
Cependant, il faut noter que l'état du verrou décrit dans ce mécanisme, à savoir le marteau, dépend de l'état de la roue à colonnes. Deux actions successives de l'utilisateur sont nécessaires pour faire passer le marteau de son état de verrouillage à un état libre et inversement.However, it should be noted that the state of the lock described in this mechanism, namely the hammer, depends on the state of the column wheel. Two successive actions of the user are necessary to move the hammer from its locking state to a free state and vice versa.
Ainsi, un tel dispositif de commande n'est pas adapté pour mettre en oeuvre la commande de mécanismes horlogers nécessitant d'être libérés puis à nouveau verrouillés automatiquement, en réponse à une action unique de l'utilisateur.Thus, such a control device is not adapted to implement the control of clock mechanisms requiring to be released and then locked again automatically, in response to a single action of the user.
Certains mécanismes de chronographe présentent une structure différente permettant d'effectuer un "retour en vol" des compteurs de temps mesurés par actionnement de l'organe de remise à zéro. Dans ce cas, les compteurs sont maintenus à zéro par le marteau aussi longtemps que l'utilisateur maintient sa pression sur l'organe de commande externe de remise à zéro. Lorsque l'organe de remise à zéro est libéré, les compteurs de chronographe sont à nouveau libres de tourner. Toutefois, dans ce cas, la position du marteau au repos est sa position levée dans laquelle il n'agit pas sur les compteurs pour les verrouiller. Aussi, un organe additionnel spécifique de verrouillage des compteurs est nécessaire lorsqu'aucune mesure d'un intervalle de temps n'est en cours.Some chronograph mechanisms have a different structure for performing a "return flight" time meters measured by actuating the reset member. In this case, the counters are maintained at zero by the hammer as long as the user maintains his pressure on the external reset control member. When the reset member is released, the chronograph counters are again free to rotate. However, in this case, the position of the hammer at rest is its raised position in which it does not act on the counters to lock them. Also, a specific additional counter lock member is needed when no measure of a time interval is in progress.

Un but principal de la présente invention est de proposer une alternative aux dispositifs connus de l'art antérieur, en proposant un tel dispositif permettant, en réponse à une action prédéfinie d'un utilisateur, de désactiver un verrou agissant sur un mobile d'un mécanisme tout en le laissant reprendre sa position de verrouillage lorsque le verrouillage du mobile est à nouveau requis.A main object of the present invention is to propose an alternative to the devices known from the prior art, by proposing such a device allowing, in response to a predefined action of a user, to deactivate a lock acting on a mobile of a mechanism while allowing it to resume its locking position when the locking of the mobile is again required.
A cet effet, la présente invention concerne plus particulièrement un dispositif de commande du type mentionné plus haut, caractérisé par le fait
que l'organe d'actionnement est monté mobile sur la base,
que le levier comprend un second organe élastique agencé pour tendre à positionner l'organe d'actionnement dans sa position active, et
que l'organe de débrayage est susceptible d'agir sur l'organe d'actionnement pour le déplacer dans sa position inactive et libérer le verrou.For this purpose, the present invention relates more particularly to a control device of the type mentioned above, characterized in that
that the actuating member is movably mounted on the base,
that the lever comprises a second elastic member arranged to tend to position the actuating member in its active position, and
that the disengaging member is able to act on the actuating member to move it to its inactive position and release the lock.
Grâce à ces caractéristiques, ce dispositif de commande garantit un retour du premier verrou dans sa position de verrouillage, après qu'il ait libéré le mobile, pour verrouiller à nouveau ce dernier.Thanks to these characteristics, this control device ensures a return of the first lock in its locking position, after it has released the mobile, to lock the latter again.
La durée au cours de laquelle le verrou est inactif suite à l'action prédéfinie de l'utilisateur peut avantageusement être adaptée selon les besoins et en fonction de divers paramètres, comme par exemple un intervalle de temps prédéfini ou encore un déplacement spatial prédéfini d'un mobile.The duration during which the lock is inactive following the predefined action of the user can advantageously be adapted according to the needs and according to various parameters, such as for example a predefined time interval or a predefined spatial displacement of a mobile.
En particulier, on notera que le dispositif selon la présente invention permet d'assurer le verrouillage du mobile après sa libération même dans le cas où un utilisateur exercerait une action prolongée sur l'organe de commande externe associé, qui maintiendrait le levier dans sa position active.In particular, it will be noted that the device according to the present invention makes it possible to lock the mobile after its release even in the case where a user exerts a prolonged action on the associated external control member, which would hold the lever in its position. active.
De manière préférée, l'organe d'actionnement est agencé sur la base de manière à pouvoir se déplacer en translation en référence à cette dernière.Preferably, the actuating member is arranged on the base so as to move in translation with reference to the latter.
Par ailleurs, l'organe de débrayage est préférablement destiné à être monté pivotant sur le bâti du mouvement horloger, en étant entraîné au moins indirectement par le mobile du mécanisme, et comprend une came susceptible d'exercer une pression sur l'organe d'actionnement pour le déplacer dans sa position inactive suivant la position angulaire de l'organe d'embrayage.Furthermore, the disengaging member is preferably intended to be pivotally mounted on the frame of the watch movement, being driven at least indirectly by the mobile mechanism, and comprises a cam may exert pressure on the body of actuation to move it to its inactive position according to the angular position of the clutch member.
Ainsi, l'action du mobile de débrayage est directement liée à l'accomplissement d'une condition prédéfinie, ici un déplacement prédéfini du mobile du mécanisme libéré par le verrou.Thus, the action of the disengaging mobile is directly related to the fulfillment of a predefined condition, here a predefined movement of the mobile mechanism released by the lock.
Selon un mode de réalisation préféré, la base est destinée à être agencée pivotante sur le bâti du mouvement horloger, l'organe d'actionnement comprenant un premier doigt agencé pour faire pivoter le premier verrou en réponse à l'action prédéfinie.According to a preferred embodiment, the base is intended to be pivotally arranged on the frame of the watch movement, the actuating member comprising a first finger arranged to pivot the first lock in response to the predefined action.
La présente invention concerne également un dispositif d'entraînement comportant un mobile denté agencé pour être verrouillé lorsque le premier verrou est dans sa première position et pour être libre de tourner lorsque le premier verrou est dans sa seconde position. Le mobile denté présente alors avantageusement une liaison cinématique avec l'organe de débrayage pour l'entraîner en rotation lorsqu'il est lui-même libre de tourner.The present invention also relates to a drive device comprising a toothed mobile arranged to be locked when the first latch is in its first position and to be free to rotate when the first latch is in its second position. The toothed mobile then advantageously has a kinematic connection with the disengaging member to drive it in rotation when it is itself free to rotate.
Le mobile denté peut être un tambour de barillet portant une denture reliée cinématiquement à l'organe de débrayage, le tambour étant solidaire en rotation d'au moins une première dent susceptible de coopérer avec un bec de verrouillage du premier verrou.The toothed mobile may be a barrel drum bearing a toothing kinematically connected to the disengagement member, the drum being rotatably connected to at least one first tooth capable of cooperating with a locking nose of the first latch.
Grâce à ces caractéristiques, le barillet peut transmettre une quantité d'énergie prédéfinie et à la demande à un mécanisme horloger.Thanks to these characteristics, the barrel can transmit a predefined quantity of energy and on demand to a clock mechanism.
Dans ce cas, on peut prévoir que le premier verrou est destiné à être monté pivotant sur un arbre solidaire du bâti du mouvement horloger, un organe amortisseur étant agencé entre l'arbre et le premier verrou pour permettre à ce dernier de se déplacer également en translation en référence au bâti du mouvement horloger.In this case, it can be provided that the first lock is intended to be pivotally mounted on a shaft integral with the watch movement frame, a damping member being arranged between the shaft and the first lock to allow the latter to move also in translation with reference to the building of the watch movement.
Par ailleurs, la présente invention concerne également un mouvement horloger comportant un dispositif d'entraînement répondant aux caractéristiques ci-dessus ainsi qu'un dispositif de sécurité agencé pour verrouiller le dispositif de commande lorsque le niveau de charge du ressort du barillet est inférieur à une première valeur prédéfinie.Furthermore, the present invention also relates to a watch movement comprising a drive device meeting the above characteristics and a safety device arranged to lock the control device when the load level of the spring of the barrel is less than one. first predefined value.
Ce mouvement horloger peut également comporter un dispositif de remontage du ressort de barillet, le dispositif de sécurité étant également agencé pour verrouiller le dispositif de remontage lorsque le niveau de charge du ressort de barillet est supérieur à une seconde valeur prédéfinie.This clock movement may also include a device for winding the mainspring, the safety device being also arranged to lock the winding device when the load level of the mainspring is greater than a second preset value.
De manière préférée, le ressort de barillet présente une première extrémité solidaire du tambour de barillet et une seconde extrémité solidaire d'un rochet de remontage, le mécanisme de remontage pouvant comporter une crémaillère présentant une denture reliée cinématiquement au rochet de remontage.Preferably, the mainspring has a first end secured to the barrel drum and a second end integral with a winding ratchet, the winding mechanism may comprise a rack having a toothing kinematically connected to the winding ratchet.
La présente invention concerne également une pièce d'horlogerie comprenant un tel mouvement horloger ainsi qu'un organe mobile visible présentant une liaison cinématique avec le tambour de barillet, l'organe mobile étant par exemple un cadran rotatif.The present invention also relates to a timepiece comprising such a watch movement and a visible movable member having a kinematic connection with the barrel drum, the movable member being for example a rotary dial.

Le dispositif de commande selon la présente invention, destiné à actionner le dispositif d'entraînement du cadran rotatif, va à présent être détaillé en relation avec les
Le dispositif de commande comporte un poussoir 24 monté rotatif sur le bâti du mouvement horloger, au moyen d'une vis 25. On notera que le ressort de rappel 23 présente deux bras symétriques et est agencé pour agir également sur le poussoir 24. Ce dernier est destiné à être actionné par un utilisateur, par l'intermédiaire d'un second poussoir externe (non illustré).The control device comprises a
Le poussoir 24 est solidaire d'un levier de commande 26 comprenant un bras 27 légèrement coudé et relié à une base 28, au moyen d'une vis 29. La base est montée pivotante sur le bâti du mouvement horloger par une première vis 30, tout en étant guidée dans ses déplacements en rotation par une seconde vis 32 fixée dans le bâti mais disposée au travers d'une courte fente 34.The
La base 28 supporte un organe d'actionnement 36 fixé sur elle par des vis 38, serrées sur des pieds-vis et, logées dans des fentes adaptées de l'organe d'actionnement, permettant à ce dernier de se déplacer en translation en référence à la base 28, entre des première et seconde positions, respectivement active et inactive. Un organe élastique 40 est par ailleurs prévu pour appliquer une force sur un doigt 41 solidaire de l'organe d'actionnement pour tendre à le repousser dans sa position active, c'est-à -dire avancée par rapport à la base 28. L'organe élastique 40 est monté sur une vis 42 solidaire de la base 28 pour permettre un ajustement de la force qu'il applique sur le doigt 41.The
L'organe d'actionnement 36 porte des premier et second doigts 44, 45 disposés de manière à dépasser de la face de la base 28 opposée à celle située du côté du bras 27. Chacun des doigts présente une extrémité inclinée par rapport à la direction de déplacement de l'organe d'actionnement en référence à la base 28.The actuating
Une goupille 46, solidaire de la base 28, émerge entre les deux doigts 44, 45 pour définir une surface d'appui destinée à coopérer avec un organe élastique supplémentaire 48, monté sur le bâti du mouvement horloger pour appliquer une force de rappel sur le levier 26 et le repousser vers sa position de repos, c'est-à -dire en direction du poussoir 24.A
Les premier et second doigts 44 et 45 sont agencés pour coopérer respectivement avec le premier verrou 10 et un second verrou 50.The first and
Le premier verrou 10 comporte une planche montée rotative sur un arbre 52 solidaire du bâti du mouvement horloger, avec interposition d'un ressort hélicoïdal 54 définissant une fonction d'amortisseur.The
La planche comprend un premier bec 56 destiné à coopérer avec le premier doigt 44, ainsi qu'un second bec 58 destiné à coopérer avec des dents 60 ménagées sur une bague 62, solidaire du tambour 4 du barillet 1, pour verrouiller ce dernier dans le sens de rotation anti-horaire sur la vue de la
Il ressort de la
De même, lorsque le ressort 5 de barillet présente un couple important, il peut être nécessaire de prévoir le second verrou 50 pour sécuriser le verrouillage du tambour 4 par le premier verrou 10, en éliminant les risques de dégagement intempestif de ce dernier. Du fait de son agencement, le second verrou 50 empêche le premier verrou 10 de se dégager de la dent 60 avec laquelle il est en prise sans autre action extérieure.Similarly, when the
Il apparaît de ce qui précède que le doigt 45 de l'organe d'actionnement 36 est destiné à actionner le second verrou 50 par l'intermédiaire d'une surface de butée 64 ménagée sur ce dernier. Plus précisément, lors de l'actionnement du poussoir 24 par un utilisateur, la base 28 du levier 26 est entraînée en rotation, de même que l'organe d'actionnement 36 dont les doigts 44 et 45 vont agir respectivement sur les premier et second verrous, le doigt 45 agissant sur le second verrou avant que le doigt 44 n'agisse sur le premier verrou. Ainsi, la sécurité du premier verrou est neutralisée avant qu'il ne soit actionné pour libérer le tambour de barillet.It appears from the above that the
On notera qu'un ressort de rappel 66 présentant trois bras agit sur les premier et second verrous, pour exercer sur eux des forces tendant à les positionner dans leur position active de verrouillage, ainsi que sur le cliquet 8 du rochet de remontage, de manière connue.Note that a
Pour éviter que le premier verrou 10 ne reste dans sa position inactive, du fait d'une action prolongée de l'utilisateur sur le poussoir 24, c'est-à -dire lorsque la durée de cette action excède le temps nécessaire au tambour de barillet pour effectuer un quart de tour, un premier dispositif de sécurité est prévu. Celui-ci présente ici la forme d'un organe de débrayage 68 monté rotatif sur le bâti du mouvement horloger, entre le tambour de barillet et le levier 26.To prevent the
L'organe de débrayage 68 comprend un pignon denté 70 solidaire d'une came 72, de forme oblongue et, agencée de manière excentrée en référence à l'axe de rotation du pignon denté. Ce dernier est dimensionné et denté de telle manière qu'il fait un tour sur lui-même lorsque le barillet 4 fait un quart de tour. Lorsque le tambour de barillet est libéré par le premier verrou 10, suite à une pression sur le poussoir 24, il entraîne l'organe de débrayage 68 en rotation, dont la came 72 agit sur l'organe d'actionnement 36 pour le repousser en direction de la base 28 et rétracter les premier et second doigts 44, 45. Grâce à cette construction, les doigts libèrent les deux verrous 10 et 50 pendant la rotation du tambour 4, même lorsque le poussoir 24 est maintenu enfoncé par l'utilisateur, garantissant dans tous les cas le verrouillage du tambour de barillet après une course prédéfinie, d'un quart de tour dans le mode de réalisation illustré à titre non limitatif.The disengaging
Lorsque le tambour est libéré, il entraîne également un premier mobile de transmission 74 relié cinématiquement à un mobile, préférablement d'affichage ou contribuant à l'apparence de la pièce.When the drum is released, it also drives a first transmission mobile 74 kinematically connected to a mobile, preferably display or contributing to the appearance of the room.
La
Le premier mobile de transmission 74 est agencé en prise avec un second mobile de transmission 76, lui-même en prise avec un pignon 78 solidaire de l'arbre 2 de transmission.The
Ce dernier porte un pignon supplémentaire 80 à son extrémité opposée, située du côté platine du mouvement horloger. Ce dernier est agencé en prise avec une bague dentée 82 destinée à être solidaire d'un mobile support 84, mobile en rotation et, destiné par exemple à porter un cadran. En particulier, on peut prévoir dans un mode de réalisation préféré que la pièce d'horlogerie correspondante comprend un cadran mobile présentant au moins un guichet ou une fenêtre qui peut prendre quatre positions angulaires différentes, en référence à la boîte de la pièce d'horlogerie, dans le but de procurer quatre apparences différentes à la pièce et/ou présenter des complications différentes dont une seule serait visible à la fois.The latter carries an
Un exemple d'une telle pièce d'horlogerie est divulgué dans le brevet
A titre indicatif, un organe de stabilisation 86 peut être prévu, celui-ci comprenant un galet 88 porté par l'extrémité d'un ressort 90. Le galet 88 est agencé de manière à coopérer avec une creusure 92 ménagée dans la bague 82 pour chacune des positions stables prévues pour le cadran mobile.As an indication, a stabilizing
Bien entendu, le nombre de positions décrit pour le cadran mobile est indicatif et non limitatif. De manière avantageuse, il devrait pouvoir en prendre deux différentes au minimum, mais pourrait en présenter plus que quatre en alternative, sans sortir du cadre de l'invention qui est défini par les revendications annexées.Of course, the number of positions described for the mobile dial is indicative and not limiting. Advantageously, it should be able to take two different minimum, but could present more than four alternative, without departing from the scope of the invention which is defined by the appended claims.
La
Suivant un mode de réalisation préféré de l'invention, on peut prévoir que l'énergie stockée dans le barillet est suffisante pour permettre plusieurs activations successives du cadran entre deux remontages. Il peut être préférable de prévoir que le dispositif de sécurité empêche l'utilisateur de déverrouiller le tambour de barillet si l'énergie résiduelle de son ressort n'est plus suffisante pour garantir son déplacement d'un quart de tour, ce qui pourrait conduire à un déphasage du cadran mobile.According to a preferred embodiment of the invention, it can be provided that the energy stored in the barrel is sufficient to allow several successive activations of the dial between two pumping. It may be preferable to provide that the safety device prevents the user from unlocking the barrel drum if the residual energy of its spring is no longer sufficient to guarantee its movement a quarter of a turn, which could lead to a phase shift of the mobile dial.
Dans ce but, le dispositif de sécurité comporte un engrenage différentiel 100, dont une première roue d'entrée 101 présente une liaison cinématique avec le rochet de remontage 6 du barillet et, une seconde roue d'entrée 102 engrène directement avec le tambour 4 du barillet 1. La première roue 101 est reliée au rochet de remontage 6 par l'intermédiaire d'un renvoi 104 permettant de faire tourner la première roue d'entrée 101 dans le sens requis pour assurer le bon fonctionnement de l'engrenage différentiel.For this purpose, the safety device comprises a
L'engrenage différentiel présente en outre une roue de sortie 106 agencée en prise avec un train d'engrenages 108 destiné à entraîner un premier mobile de comptage 110 portant une première came 112, présentant sensiblement la forme d'une portion de disque, et un doigt 114 adjacent à la came.The differential gear further has an
Le premier mobile de comptage 110 coopère avec un second mobile de comptage 116 comprenant une denture (non visible), agencée pour déplacer un mobile de verrouillage 118 entre deux positions extrêmes, ainsi qu'une seconde came 120 présentant au moins partiellement la forme d'une croix de Malte à au moins deux branches 122, ici quatre.The
La première came 112 est agencée de manière à coopérer avec les extrémités libres des branches 122 pour empêcher une rotation du second mobile de comptage 116.The
Le doigt 114 est destiné à s'engager entre deux branches 122 du second mobile de comptage 116 pour entraîner ce dernier en rotation, dans un sens ou dans l'autre.The
La denture du second mobile de comptage 116 est agencée en prise avec une crémaillère (référence numérique 124 sur la
Le mobile de verrouillage 118 porte des premier et second bras 126, 128 destinés à coopérer respectivement avec les premier et second poussoirs 14, 24, pour en assurer le verrouillage.The locking mobile 118 carries first and
Le fonctionnement du dispositif de sécurité va maintenant être exposé en relation avec la
Pour rappel, une action sur le premier poussoir 14 a pour effet de remonter le ressort 5 du barillet 1, tandis qu'une action sur le second poussoir 24 a pour effet de libérer le tambour 4 du barillet et donc de décharger au moins partiellement le ressort 5.As a reminder, an action on the
Dans la configuration illustrée sur la
On notera par ailleurs que la came 112 définit également un arrêt pour le premier mobile de comptage 110 par l'intermédiaire du doigt 114.Note also that the
Si, partant de cette configuration, l'utilisateur souhaite faire tourner le mobile support 84 d'un quart de tour, il actionne le second poussoir 24. Ce faisant, il libère le tambour 4 qui tourne d'un quart de tour et entraîne la rotation de la seconde roue d'entrée 102 de l'engrenage différentiel 100.If, based on this configuration, the user wishes to turn the
La rotation de la seconde roue 102 entraîne une rotation du premier mobile de comptage 110 dans le sens de rotation anti-horaire.The rotation of the
L'angle de rotation du premier mobile de comptage 110 est fonction de la démultiplication introduite notamment par le train d'engrenages 108.The angle of rotation of the
Admettons, à titre d'exemple non limitatif et pour simplifier les présentes explications, qu'une rotation d'un quart de tour du tambour de barillet entraîne une rotation d'un tour complet du premier mobile de comptage 110. Dans ce cas, le doigt 114 pénètre dans l'espace situé entre deux branches 122 de la seconde came 120, lors de la fin de la course du premier mobile de comptage, pour faire tourner cette dernière d'un pas dans le sens horaire (le pas étant défini ici par les branches 122). La rotation du second mobile de comptage 116 dans le sens horaire induit un déplacement de la crémaillère 124 en direction du second poussoir 24, libérant ainsi le premier poussoir 14.As a nonlimiting example and to simplify the present explanations, let us suppose that a rotation of a quarter turn of the barrel drum causes rotation of a complete revolution of the
A partir de là , le premier poussoir 14 peut à nouveau être actionné une fois pour remonter le ressort de barillet avant d'être à nouveau verrouillé.From there, the
A l'inverse, le second poussoir 24 peut encore être actionné plusieurs fois avant d'être verrouillé par le second bras 128 du mobile de verrouillage 118. Plus précisément, dans l'exemple illustré ici à titre non limitatif, le second poussoir 24 peut encore être actionné trois fois avant d'être verrouillé.Conversely, the
Bien entendu, l'homme du métier ne rencontrera pas de difficulté particulière pour adapter le dispositif de sécurité aux propriétés du ressort 5 de barillet. On peut par exemple prévoir que le ressort 5 est calibré de telle manière qu'il permet d'actionner huit fois la rotation du mobile support 84. Dans ce cas, le premier mobile de comptage 110 ne ferait qu'un demi-tour à chaque actionnement du second poussoir 24 à la place d'un tour complet.Of course, those skilled in the art will not encounter any particular difficulty in adapting the safety device to the properties of the barrel spring. For example, provision may be made for the
On notera que les bras 126, 128 sont montés sur le mobile de verrouillage 118 en présentant un léger jeu en rotation, des ressorts 130 étant prévus pour assurer leur bonne coopération avec les poussoirs. Plus particulièrement, cette construction permet de garantir une bonne mise en place des bras dans leur position de verrouillage. En effet, lorsque le mobile de verrouillage vient se placer dans l'une ou l'autre des positions de verrouillage, le poussoir 14 ou 24 correspondant est encore actionné et se trouve sur le trajet de son bras de verrouillage 126 ou 128. Dans cette phase intermédiaire, le bras pivote en déformant son ressort 130 jusqu'à ce que le poussoir soit libéré et permette au bras de se positionner dans sa position de verrouillage, sous l'effet du ressort.Note that the
La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en oeuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple le fait que le barillet est destiné à entraîner un cadran mobile, voire même le fait que le premier verrou coopère avec un barillet. En effet, il est possible de mettre en oeuvre la présente invention pour que le premier verrou agisse sur un mobile quelconque, de manière générale, pour l'empêcher de tourner, sans sortir du cadre de la présente invention qui est défini par les revendications annexées. De manière similaire, les formes spécifiquement illustrées et décrites pour les différents constituants ne sont pas limitatives. A titre d'exemple, il est possible de prévoir que l'organe de débrayage n'agit que de façon indirecte sur l'organe d'actionnement. Par ailleurs, il est également possible de prévoir que les dents 60 coopérant avec le premier verrou ne soient pas réparties de manière régulière autour de la bague 62.The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular features which have just been described, for example the fact that the barrel is intended to drive a mobile dial, or even the fact that the first latch cooperates with a barrel. Indeed, it is possible to implement the present invention so that the first latch acts on any mobile in general, to prevent it from rotating, without departing from the scope of the present invention which is defined by the appended claims . Similarly, the forms specifically illustrated and described for the various constituents are not limiting. For example, it is possible to provide that the disengaging member acts only indirectly on the actuating member. Moreover, it is also possible to provide that the
L'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins, et mettre en oeuvre un dispositif de commande ne reprenant qu'en partie les caractéristiques exposées ici, sans sortir du cadre de la présente invention qui est défini par les revendications annexées.The person skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to his own needs, and implement a control device that only partially reproduces the features set forth herein, without departing from the scope of this document. invention which is defined by the appended claims.
Bien entendu, si l'invention n'est pas limitée à la mise en oeuvre d'un barillet, elle n'est pas non plus limitée à la mise en oeuvre du mécanisme de remontage décrit et illustré et, encore moins à la mise en oeuvre du dispositif de sécurité, lorsqu'un barillet est concerné.Of course, if the invention is not limited to the implementation of a cylinder, it is not limited to the implementation of the winding mechanism described and illustrated and even less to the implementation of safety device, when a cylinder is concerned.
