Description

L'invention concerne une pièce d'horlogerie comportant un mécanisme de sonnerie à répétition, notamment une montre-bracelet à grande sonnerie.The invention relates to a timepiece comprising a recurring striking mechanism, in particular a large ring wristwatch.

L'invention concerne plus particulièrement une pièce d'horlogerie comportant un rouage de minuterie qui entraîne des moyens d'affichage analogiques et un rouage de sonnerie qui entraîne un mécanisme de sonnerie, dans laquelle le rouage de minuterie est entraîné en rotation par un barillet comportant un ressort de barillet, une denture qui engrène avec le rouage de minuterie, et un rochet de remontoir coaxial au barillet, le rochet de remontoir étant solidaire en rotation de l'arbre d'entraînement du barillet, et dans laquelle un organe de remontage est prévu pour engrener avec le rochet de remontoir en vue d'armer le ressort de barillet au cours d'une phase d'armement.The invention more particularly relates to a timepiece comprising a timer train which drives analog display means and a ring gear which drives a striking mechanism, in which the timer train is rotated by a cylinder comprising a mainspring, a toothing that meshes with the time train, and a winding ratchet coaxial with the barrel, the winding ratchet being integral in rotation with the drive shaft of the barrel, and in which a winding member is provided to mesh with the winding ratchet to arm the mainspring during an arming phase.

De telles pièces d'horlogerie sont connues depuis longtemps, en particulier dans le domaine des montres dites compliquées telles que les montres à répétition ou les montres à grande sonnerie. Pour une bonne compréhension de l'état de la technique dans le domaine des montres compliquées, on pourra se reporter à l'ouvrage de François Lecoultre intitulé "Les montres compliquées" (ISBN 2-88175-000-1), qui comporte notamment plusieurs chapitres relatifs aux montres équipées d'un mécanisme de sonnerie (pages 97 à 205 ), dont un chapitre dédié aux montres à grande sonnerie (182 à 205).Such timepieces have been known for a long time, particularly in the field of so-called complicated watches such as repeating watches or big-bell watches. For a good understanding of the state of the art in the field of complicated watches, reference can be made to François Lecoultre entitled "Complicated Watches" (ISBN 2-88175-000-1), which includes several chapters relating to watches equipped with a striking mechanism (pages 97 to 205 ), including a chapter dedicated to big-bell watches (182 to 205).

Les montres à grande sonnerie comportent généralement deux rouages, un rouage de minuterie pour l'entraînement des moyens d'affichage de l'heure tels que des aiguilles, et un rouage de sonnerie pour l'entraînement du mécanisme de sonnerie, chaque rouage comportant son propre barillet et ressort de barillet pour fournir l'énergie motrice à l'entraînement du rouage.The large-bell watches generally comprise two wheels, a timer train for driving the time display means such as hands, and a ring gear for driving the striking mechanism, each wheel including its own barrel and barrel spring to provide motive power to drive the gear train.

Pour diminuer le nombre d'éléments constituant la pièce d'horlogerie et dans un objectif de gain de place, il a été proposé d'utiliser un barillet unique pour les deux rouages. C'est le cas dans les documents CH 50 729 et CH 23 477 qui décrivent et représentent chacun une pièce d'horlogerie dans laquelle le rouage de minuterie est entraîné par le tambour denté du barillet et le rouage de sonnerie est entraîné par une roue dentée coaxiale à l'arbre de barillet et liée en rotation à l'arbre de barillet par un cliquet coopérant par un rochet fixé sur l'arbre de barillet.To reduce the number of elements constituting the timepiece and in order to save space, it has been proposed to use a single barrel for the two wheels. This is the case in the documents CH 50 729 and CH 23,477 each of which describes and represents a timepiece in which the timer wheel is driven by the barrel toothed drum and the ring gear is driven by a gearwheel coaxial with the barrel shaft and rotatably connected to the shaft barrel by a pawl cooperating with a ratchet attached to the barrel shaft.

Ces solutions ne sont pas complètement satisfaisantes car elles nécessitent une modification de la structure du barillet pour le rendre apte à supporter cette double utilisation. En particulier, il est nécessaire d'agencer un système de cliquet et de rochet supplémentaire sur la face supérieure du barillet, alors que du côté opposé il faut agencer le rochet de remontoir, ce qui est pénalisant pour l'encombrement axial du barillet.These solutions are not completely satisfactory because they require a modification of the structure of the barrel to make it suitable to support this double use. In particular, it is necessary to arrange an additional ratchet and ratchet system on the upper face of the barrel, while on the opposite side it is necessary to arrange the winding ratchet, which is disadvantageous for the axial size of the barrel.

La présente invention vise à remédier à ces inconvénients en proposant une solution alternative pour réaliser un mécanisme d'entraînement à un seul barillet minimisant l'encombrement axial et facilitant les opérations d'assemblage.The present invention aims to remedy these drawbacks by proposing an alternative solution for producing a drive mechanism with a single barrel minimizing axial size and facilitating assembly operations.

La présente invention vise aussi à proposer une solution permettant d'utiliser un barillet standard.The present invention also aims at providing a solution for using a standard barrel.

Dans ce but, l'invention propose une pièce d'horlogerie du type décrit précédemment, caractérisée en ce que le rochet de remontoir entraîne en rotation le rouage de sonnerie via un mobile intermédiaire d'axe déporté par rapport à l'axe du barillet, et en ce que le mobile intermédiaire comporte un dispositif à cliquet permettant de débrayer le rochet de remontoir par rapport au rouage de sonnerie lors de la phase d'armement du ressort.For this purpose, the invention proposes a timepiece of the type described above, characterized in that the winding ratchet causes the ring gear train to rotate by means of an intermediate wheel having an offset axis with respect to the axis of the barrel, and in that the intermediate mobile comprises a ratchet device for disengaging the winding ratchet relative to the ring gear during the arming phase of the spring.

Grâce à la pièce d'horlogerie selon l'invention, il est possible d'utiliser un barillet standard pour entraîner à la fois le rouage de minuterie et le rouage de sonnerie, ce qui limite le nombre de références différentes pour réaliser, par exemple, un modèle de pièce d'horlogerie avec sonnerie et un modèle sans sonnerie.Thanks to the timepiece according to the invention, it is possible to use a standard cylinder to drive both the clockwork and the ring gear, which limits the number of different references to achieve, for example, a model of timepiece with ringing and a model without ringing.

Comme la structure du barillet n'est pas modifiée, son encombrement axial n'est pas modifié, ce qui facilite son agencement dans la pièce d'horlogerie.As the structure of the barrel is not modified, its axial size is not changed, which facilitates its arrangement in the timepiece.

Selon un mode de réalisation avantageux, le mobile intermédiaire comporte une roue intermédiaire qui est entraînée en rotation par le rochet de remontoir, une roue à rochet qui est liée en rotation à la roue intermédiaire, et un pignon intermédiaire qui est lié en rotation à la roue à rochet par au moins un cliquet et qui engrène avec le rouage de sonnerie. Le mobile intermédiaire selon l'invention est donc particulièrement simple de structure et peu encombrant, ce qui facilite son agencement dans la pièce d'horlogerie.According to an advantageous embodiment, the intermediate mobile comprises an intermediate wheel which is rotated by the winding ratchet, a ratchet wheel which is rotatably connected to the intermediate wheel, and an intermediate gear which is connected in rotation to the ratchet wheel by at least one ratchet and which meshes with the ring gear. The intermediate mobile according to the invention is particularly simple structure and space-saving, which facilitates its arrangement in the timepiece.

De préférence, la roue intermédiaire s'étend dans le même plan que le rochet de remontoir ce qui minimise l'encombrement axial du mobile intermédiaire.Preferably, the intermediate wheel extends in the same plane as the winding ratchet which minimizes the axial size of the intermediate mobile.

La roue à rochet comporte un prolongement axial et la roue intermédiaire est montée solidaire à rotation sur ce prolongement axial. On obtient ainsi un système d'entraînement particulièrement compact et de faible encombrement axial pour transmettre le couple du rochet de remontoir au rouage de sonnerie.The ratchet wheel has an axial extension and the intermediate wheel is rotatably mounted on the axial extension. This provides a particularly compact drive system and low axial size to transmit the torque of the winding ratchet ring gear.

Avantageusement, la roue à rochet comporte au moins deux cliquets, et le pignon intermédiaire est muni d'une roue d'inversion coaxiale qui est liée en rotation au pignon intermédiaire avec un débattement angulaire déterminé et qui comporte des moyens pour commander la levée des cliquets lorsque l'on provoque un mouvement angulaire relatif de la roue d'inversion par rapport au pignon intermédiaire. Ceci facilite les opérations de maintenance en permettant de commander la levée de tous les cliquets avec un seul outil en vue de désarmer le ressort de barillet, notamment lorsque l'on souhaite intervenir sur le mécanisme de sonnerie.Advantageously, the ratchet wheel comprises at least two ratchets, and the intermediate gear is provided with a coaxial inversion wheel which is rotatably connected. intermediate gear with a determined angular displacement and which comprises means for controlling the lifting of the pawls when it causes a relative angular movement of the reversing wheel relative to the intermediate gear. This facilitates maintenance operations by controlling the lifting of all pawls with a single tool to disarm the mainspring, especially when it is desired to intervene on the striking mechanism.

Selon un mode de réalisation avantageux, un renvoi auxiliaire engrène avec le pignon intermédiaire, et le renvoi auxiliaire est sollicité en rotation dans le sens de l'entraînement du rouage de sonnerie, de manière à maintenir un couple de blocage sur le pignon intermédiaire pendant la phase d'armement. On limite ainsi les risques de déclenchement intempestif de la sonnerie, pendant les phases d'armement.According to an advantageous embodiment, an auxiliary gear meshes with the intermediate gear, and the auxiliary gear is biased in rotation in the direction of driving the striking gear, so as to maintain a locking torque on the intermediate gear during the arming phase. This limits the risk of nuisance tripping of the ring, during arming phases.

Avantageusement, le rochet de remontoir engrène avec un renvoi principal qui engrène avec le mobile intermédiaire. On obtient ainsi une démultiplication adéquate tout en minimisant l'encombrement des éléments d'entraînement reliant le rochet de remontoir au rouage de sonnerie.Advantageously, the winding ratchet meshes with a main return which meshes with the intermediate mobile. This provides an adequate gearing while minimizing the size of the drive elements connecting the ratchet winding ring gear.

Sur la figure 1, on a représenté schématiquement un organe de déclenchement 19 de la sonnerie, constitué par exemple par une bascule de déclenchement.The ringing mechanism 18 of the wristwatch 10 according to the invention is, for example, of the big ring type, that is to say that it is capable of ringing the hours and the quarters, or by an automatic triggering. or by triggering on demand under the effect of a manual intervention M2. On the figure 1 schematically shows a trigger member 19 of the ring, consisting for example of a trigger rocker.

Le rouage de minuterie 12 est entraîné en rotation par un barillet 20, qui est représenté sur les figures 2 et 3, comportant un tambour 22 cylindrique dans lequel est logé un ressort 24 de barillet, un arbre d'entraînement 26 sur lequel est fixé une première extrémité 28 du ressort 24, et un couvercle 30 qui ferme le tambour 22 à son extrémité axiale supérieure.The clock train 12 is rotated by a cylinder 20, which is shown on the figures 2 and 3 , comprising a cylindrical drum 22 in which is housed a barrel spring 24, a drive shaft 26 on which is fixed a first end 28 of the spring 24, and a lid 30 which closes the drum 22 at its upper axial end.

Dans la suite de la description, on utilisera à titre non limitatif une orientation verticale suivant l'axe A1 de l'arbre d'entraînement 26 du barillet 20.In the rest of the description, use will be made without limitation of a vertical orientation along the axis A1 of the drive shaft 26 of the barrel 20.

Le ressort 24 est une lame en forme de spirale enroulée autour de l'arbre d'entraînement 26. Le tambour 22 comporte un dégagement 32 dans sa paroi axiale interne qui permet la fixation d'une seconde extrémité 34 du ressort 24.The spring 24 is a spiral-shaped blade wound around the drive shaft 26. The drum 22 has a clearance 32 in its inner axial wall which allows the attachment of a second end 34 of the spring 24.

Le tambour 22 comporte une denture externe 36 qui engrène avec un pignon de huitaine minuterie 37 solidaire en rotation de la roue de huitaine minuterie 39 (visibles sur la figure 3) du rouage de minuterie 12, de manière à transmettre le couple fourni par le ressort 24 au rouage de minuterie 12. On a représenté l'axe de centre minuterie 41 qui est pourvu d'un pignon 43 engrenant avec la roue de huitaine minuterie 39.The drum 22 has an external toothing 36 which meshes with an eight-minute timer pinion which is rotatably connected to the eight-minute timer wheel 39 (visible on the figure 3 ) of the timer train 12, so as to transmit the torque supplied by the spring 24 to the clock train 12. There is shown the center axis timer 41 which is provided with a pinion 43 meshing with the timer wheel of eight 39 .

Un rochet de remontoir 38 coaxial au barillet 20 est monté sur l'extrémité axiale supérieure 40 de l'arbre d'entraînement 26 par l'intermédiaire d'un carré 42, de manière que le rochet de remontoir 38 soit solidaire en rotation de l'arbre d'entraînement 26.A winding ratchet 38 coaxial with the barrel 20 is mounted on the upper axial end 40 of the drive shaft 26 via a square 42, so that the winding ratchet 38 is integral in rotation with the drive shaft 26.

Un organe de remontage 44, qui peut être commandé par une action manuelle M1 sur une tige de remontoir (non représentée), est prévu pour provoquer l'armement du ressort de barillet 24, au cours d'une phase d'armement. L'organe de remontage 44 est constitué ici par un pignon qui engrène avec le rochet de remontoir 38 de manière à entraîner en rotation le rochet de remontoir 38 dans le sens de l'armement du ressort 24, dans le sens horaire en considérant la figure 3.A winding member 44, which can be controlled by a manual action M1 on a winding stem (not shown), is provided to cause the cocking spring 24 to be cocked during a cocking phase. The winding member 44 is constituted here by a pinion which meshes with the winding ratchet 38 so as to rotate the winding ratchet 38 in the direction of arming the spring 24, in a clockwise direction by considering the figure 3 .

Conformément aux enseignements de l'invention, le rochet de remontoir 38 entraîne en rotation le rouage de sonnerie 16 via un mobile intermédiaire 45 dont l'axe A2 de rotation est déporté par rapport à l'axe A1 du barillet 20. Le mobile intermédiaire 45 est pourvu d'un dispositif 47 à cliquets permettant de débrayer le rochet de remontoir 38 par rapport au rouage de sonnerie 16 pendant la phase d'armement du ressort 24.In accordance with the teachings of the invention, the winding ratchet 38 rotates the ring gear 16 via an intermediate wheel 45 of which the axis A2 of rotation is offset relative to the axis A1 of the cylinder 20. The intermediate mobile 45 is provided with a device 47 with ratchets for disengaging the winding ratchet 38 relative to the ring gear 16 during the phase arming the spring 24.

Le mobile intermédiaire 45 comporte une roue intermédiaire 46 qui est liée en rotation à une roue à rochet 48. La roue à rochet 48 est liée en rotation, dans le sens du désarmement du ressort 24 de barillet, via deux cliquets 50, 52, à un pignon intermédiaire 54 engrenant avec le rouage de sonnerie 16. Le dispositif 47 à cliquets est constitué ici par la roue à rochet 48, les cliquets 50, 52, et le pignon intermédiaire 54.The intermediate wheel 45 comprises an intermediate wheel 46 which is rotatably connected to a ratchet wheel 48. The ratchet wheel 48 is rotatably connected in the disarming direction of the barrel spring 24 via two pawls 50, 52, to an intermediate pinion 54 meshing with the ring gear 16. The ratchet device 47 is constituted here by the ratchet wheel 48, the pawls 50, 52, and the intermediate pinion 54.

Sur la figure 3, on a représenté l'axe de centre sonnerie 55 qui est pourvu d'un pignon 57 engrenant avec le pignon intermédiaire 54.On the figure 3 the ring center axis 55 which is provided with a pinion 57 meshing with the intermediate gear 54 is shown.

Lorsque l'organe de déclenchement 19 est actionné, que ce soit automatiquement ou par une intervention manuelle M2, il libère le rouage de sonnerie 16 qui est entraîné en rotation sous l'effet de la détente du ressort 24 de barillet, le ressort 24 se dévidant alors dans le sens du désarmement en provoquant la rotation du rochet de remontoir 38, ici dans le sens anti-horaire. Le rochet de remontoir 38 est donc retenu dans le sens du désarmement du ressort 24 de barillet par le rouage de sonnerie 16 qui reste bloqué tant qu'il n'a pas été libéré par l'organe de déclenchement 19.When the trigger member 19 is actuated, whether automatically or by a manual intervention M2, it releases the ring gear 16 which is rotated under the effect of the relaxation of the spring 24 of the barrel, the spring 24 is then unwinding in the direction of disarmament by causing the rotation of the winding ratchet 38, here in the counterclockwise direction. The winding ratchet 38 is thus retained in the disarming direction of the barrel spring 24 by the ring gear 16 which remains blocked until it has been released by the trigger member 19.

Selon le mode de réalisation représenté ici, le rochet de remontoir 38 engrène avec un renvoi principal 56 qui engrène avec la roue intermédiaire 46. Le renvoi principal 56 et la roue intermédiaire 46 s'étendent dans le même plan que le rochet de remontoir 38.According to the embodiment shown here, the winding ratchet 38 meshes with a main return 56 which meshes with the intermediate wheel 46. The main return 56 and the intermediate wheel 46 extend in the same plane as the winding ratchet 38.

Selon un mode de réalisation avantageux, illustré en particulier par la figure 4, la roue à rochet 48 est annulaire et comporte, vers le haut, un prolongement axial 58 tubulaire. La roue intermédiaire 46 est chassée sur ce prolongement axial 58 de sorte que la roue à rochet 48 est coaxiale et solidaire à rotation par rapport à la roue intermédiaire 46. Le pignon intermédiaire 54 est ici réalisé d'une seule pièce avec son arbre 60 de rotation qui s'étend axialement à l'intérieur de la roue à rochet 48 et du prolongement axial 58. L'arbre 60 du pignon intermédiaire 54 est monté libre à rotation par rapport à la roue à rochet 48. La roue à rochet 48 et la roue intermédiaire 46 sont portées par le pignon intermédiaire 54.According to an advantageous embodiment, illustrated in particular by the figure 4 , the ratchet wheel 48 is annular and comprises, upward, a tubular axial extension 58. The intermediate wheel 46 is driven on this axial extension 58 so that the ratchet wheel 48 is coaxial and rotationally fixed relative to the intermediate wheel 46. The intermediate gear 54 is here made in one piece with its shaft 60. rotation that extends axially inside the ratchet wheel 48 and the axial extension 58. The shaft 60 of the intermediate gear 54 is rotatably mounted relative to the ratchet wheel 48. The ratchet wheel 48 and the intermediate wheel 46 are carried by the intermediate gear 54.

Chaque cliquet 50, 52 est monté pivotant autour d'un axe de cliquet 62, 64 qui est fixé dans la face transversale supérieure 66 du pignon intermédiaire 54. Les deux axes de cliquet 62, 64 sont ici diamétralement opposés. Chaque cliquet 50, 52 est sollicité vers les dents de la roue à rochet 48 par une lame élastique 68, 70 de rappel associée.Each pawl 50, 52 is pivotally mounted about a pawl pin 62, 64 which is fixed in the upper transverse face 66 of the intermediate pinion 54. The two pawl pins 62, 64 are here diametrically opposed. Each ratchet 50, 52 is biased toward the teeth of the ratchet wheel 48 by an associated resilient leaf 68, 70.

Avantageusement, une roue d'inversion 72 est intercalée axialement entre la roue à rochet 48 et le pignon intermédiaire 54. La roue d'inversion 72 comporte deux lumières 74, 76 oblongues à travers lesquelles s'étendent respectivement les deux axes de cliquet 62, 64. Les lames élastiques 68, 70 sont ici fixées sur la face transversale supérieure 78 de la roue d'inversion 72.Advantageously, an inversion wheel 72 is interposed axially between the ratchet wheel 48 and the intermediate gear wheel 54. The inversion wheel 72 comprises two oblong slots 74, 76 through which the two pawl axes 62 respectively extend, 64. The elastic blades 68, 70 are here fixed on the upper transverse face 78 of the reversing wheel 72.

La roue d'inversion 72 est liée en rotation au pignon intermédiaire 54 par la butée des axes de cliquet 62, 64 contre le bord d'extrémité de la lumière associée 74, 76. Les lumières 74, 76 permettent un débattement angulaire déterminé par la longueur circonférentielle des lumières 74, 76, entre la roue d'inversion 72 et le pignon intermédiaire 54.The reversing wheel 72 is rotatably connected to the intermediate gear 54 by the abutment of the pawl pins 62, 64 against the end edge of the associated light 74, 76. The lights 74, 76 allow an angular deflection determined by the circumferential length of the lumens 74, 76, between the reversing wheel 72 and the intermediate gear 54.

Un pivotement relatif de la roue d'inversion 72 par rapport au pignon intermédiaire 54 provoque la levée des cliquets 62, 64 en raison du déplacement de l'extrémité d'appui 80 de chaque lame élastique 68, 70 du côté opposé à l'axe de pivotement du cliquet 62, 64 associé, les lames 68, 70 ne sollicitant plus les cliquets 62, 64 vers la roue à rochet 48.Relative pivoting of the reversing wheel 72 relative to the intermediate gear 54 causes the pawls 62, 64 to rise due to the displacement of the bearing end 80 of each elastic blade 68, 70 on the side opposite the axis. pivoting the pawl 62, 64 associated, the blades 68, 70 no longer soliciting the pawls 62, 64 to the ratchet wheel 48.

La roue d'inversion 72 vise à faciliter les opérations de maintenance de la pièce d'horlogerie 10 en permettant de lever les cliquets 50, 52 pour désarmer le ressort 24, comme cela sera expliqué par la suite.The inversion wheel 72 aims to facilitate the maintenance operations of the timepiece 10 by lifting the pawls 50, 52 to disarm the spring 24, as will be explained later.

Selon une autre caractéristique avantageuse de l'invention, un renvoi auxiliaire 82 engrène avec le pignon intermédiaire 54. Le renvoi auxiliaire 82 est sollicité en rotation dans le sens de l'entraînement du rouage de sonnerie 16, c'est-à-dire dans le sens du désarmement du ressort 24 de barillet, de manière à maintenir un couple de blocage sur le pignon intermédiaire 54 pendant la phase d'armement du ressort 24 de barillet.According to another advantageous characteristic of the invention, an auxiliary gear 82 meshes with the intermediate gear 54. The auxiliary gear 82 is urged in rotation in the direction of driving the striking gear 16, that is to say in the disarming direction of the spring 24 of the barrel, so as to maintain a locking torque on the intermediate gear 54 during the cocking phase of the spring 24 of the barrel.

On explique maintenant le fonctionnement de la pièce d'horlogerie 10 selon l'invention.The operation of the timepiece 10 according to the invention is now explained.

Dans une situation neutre, c'est-à-dire en l'absence de sonnerie ou d'opération d'armement, la pièce d'horlogerie 10 indique l'heure courante et le mécanisme de sonnerie 18 est bloqué dans une position prête pour le déclenchement d'une sonnerie. Le rouage de minuterie 12 est entraîné en rotation par le tambour de barillet 22 qui tourne, ici dans le sens horaire, sous l'effet du ressort 24 de barillet qui se déroule.In a neutral situation, that is to say in the absence of ringing or arming operation, the timepiece 10 indicates the current time and the striking mechanism 18 is locked in a position ready for triggering a ring. The clock train 12 is rotated by the barrel drum 22 which rotates, here clockwise, under the effect of the barrel spring 24 which takes place.

Dans cette situation neutre, le ressort 24 de barillet se déroule uniquement dans un sens puisque, du côté de sa première extrémité 28, il est fixe, le rochet de remontoir 38 étant retenu dans une position angulaire fixe par le rouage de sonnerie 16 et le mécanisme de sonnerie 18.In this neutral situation, the barrel spring 24 only proceeds in one direction since, on the side of its first end 28, it is fixed, the ratchet winder 38 being held in a fixed angular position by the ring gear 16 and the striking mechanism 18.

Au cours d'une phase de sonnerie, l'organe de déclenchement 19 libère le mécanisme de sonnerie 18, ce qui provoque la libération du rouage de sonnerie 16 qui est entraîné en rotation par le rochet de remontoir 38 qui tourne alors avec l'arbre 40 de barillet, ici dans le sens anti-horaire.During a ringing phase, the trigger member 19 releases the striking mechanism 18, which causes the release of the ring gear 16 which is rotated by the winding ratchet 38 which then rotates with the shaft 40 barrel, here in the counterclockwise direction.

Pendant la phase de sonnerie, le ressort 24 de barillet se déroule par ses deux extrémités puisque sa première extrémité 28 est liée en rotation au rochet de remontoir 38, alors que sa seconde extrémité 34 continue de se déplacer avec le tambour 22 de barillet pour entraîner le rouage de minuterie 12 et continuer d'afficher l'heure courante.During the ringing phase, the barrel spring 24 is unwound at both ends since its first end 28 is rotatably connected to the winding ratchet 38, while its second end 34 continues to move with the barrel drum 22 to drive. timer train 12 and continue to display the current time.

Au cours d'une phase d'armement, appelée aussi phase de remontage, l'organe de remontage 44 engrène avec le rochet de remontoir 38 pour l'entraîner en rotation, ici dans le sens horaire, et ainsi armer le ressort 24 de barillet.During an arming phase, also called winding phase, the winding member 44 meshes with the winding ratchet 38 to drive it in rotation, here in the clockwise direction, and thus to cock the barrel spring 24 .

La rotation du rochet de remontoir 38 provoque la rotation de la roue intermédiaire 46, via le renvoi principal 56, dans le sens inverse par rapport à la phase de sonnerie, ici dans le sens horaire. La roue à rochet 48 tourne avec la roue intermédiaire 46 en provoquant la levée des cliquets 50, 52, à l'encontre des lames élastiques 68, 70, grâce à ses dents de loup 49, de sorte que le pignon intermédiaire 54 reste sensiblement immobile angulairement.The rotation of the winding ratchet 38 causes the rotation of the intermediate wheel 46, via the main return 56, in the opposite direction with respect to the ringing phase, here in the clockwise direction. The ratchet wheel 48 rotates with the intermediate wheel 46 causing the ratchets 50, 52 to rise against the elastic blades 68, 70, thanks to its wolf teeth 49, so that the intermediate gear 54 remains substantially immobile. angularly.

Pendant la phase d'armement, le renvoi auxiliaire 82 maintient un couple de blocage sur le pignon intermédiaire 54 ce qui compense les jeux angulaires et évite que, en raison du relâchement du couple exercé par le rochet de remontoir 38 sur le rouage de sonnerie 16 dans le sens du déclenchement de la sonnerie, les éléments du mécanisme de sonnerie 18 se déplacent, ce qui risquerait de provoquer un déclenchement de sonnerie impromptu.During the arming phase, the auxiliary return 82 maintains a locking torque on the intermediate gear 54 which compensates for the angular clearances and prevents that, due to the relaxation of the torque exerted by the winding ratchet 38 on the ring gear 16 in the direction of the triggering of the ring, the elements of the striking mechanism 18 move, which could cause an impromptu ringing trigger.

Lors d'une opération de maintenance, il peut s'avérer nécessaire de permettre le désarmement du ressort 24 de barillet sans avoir à déclencher une série de sonneries, notamment pour soulager le mécanisme de sonnerie 18. En entraînant en rotation la roue d'inversion 72 par rapport au pignon intermédiaire 54, par exemple au moyen d'un outil ou d'un râteau équipant la pièce d'horlogerie 10 et engrenant avec des dents de la roue d'inversion 72, dans le sens anti-horaire en considérant la figure 3, on provoque la levée des cliquets 50, 52 ce qui permet le déroulement complet du ressort 24 de barillet sans entraîner en rotation le rouage de sonnerie 16.During a maintenance operation, it may be necessary to allow the disarming of the barrel spring 24 without having to trigger a series of rings, in particular to relieve the striking mechanism 18. By rotating the inversion wheel 72 relative to the intermediate gear 54, for example by means of a tool or a rake equipping the timepiece 10 and meshing with the teeth of the reversing wheel 72, in the counter-clockwise direction by considering the figure 3 the pawls 50, 52 are raised, thereby allowing the barrel spring 24 to unwind without rotating the ring gear 16.

La présente invention a été décrite ici en référence avec une pièce d'horlogerie 10 équipée d'un mécanisme à grande sonnerie. Bien entendu, l'invention s'applique à toute pièce d'horlogerie comportant un rouage de sonnerie et un rouage de minuterie, et dans laquelle l'énergie pour la sonnerie est fournie par un barillet, notamment les pièces d'horlogerie avec une sonnerie à déclenchement programmé (fonction réveil) et les pièces d'horlogerie à petite sonnerie.The present invention has been described here with reference to a timepiece 10 equipped with a large ring mechanism. Of course, the invention applies to any timepiece comprising a ring gear and a gear train timer, and wherein the energy for the ring is provided by a cylinder, including timepieces with a timed alarm (alarm function) and timepieces small bell.
