Abstract

When a striking command is issued, a catch (36) is released allowing a spring (25) to rotate a curved rack (28) and lever (22). The lever has a contact finger (26) which releases a surprise jumper (8). The jumper moves under spring (10) loading to adjust the position of a surprise (5) mounted on a minutes spiral (4) and the contact finger with surprise insulator (47) continues the movement to block the hours spiral (16).

Description

La présente invention concerne une pièce d'horlogerie à sonnerie comportant un mobile de centre faisant un tour par heure et pourvu d'un premier limaçon et d'une surprise associée à celui-ci, un deuxième limaçon, une pièce à crémaillère reliée à une commande de sonnerie et agencée pour pivoter à partir d'une position de repos lorsque ladite commande est actionnée, la pièce à crémaillère étant pourvue d'un palpeur agencé pour buter contre le deuxième limaçon lorsque la commande de sonnerie est actionnée, un sautoir de surprise agencé pour s'appuyer contre la surprise sous l'effet d'un ressort pour faire pivoter la surprise sur le premier limaçon, et un dispositif isolateur de surprise agencé pour tenir le sautoir de surprise à l'écart de la surprise lorsque la pièce à crémaillère est en position de repos.The present invention relates to a clockwork timepiece comprising a center mobile making one turn per hour and provided with a first snail and a surprise associated therewith, a second snail, a rack piece connected to a ring control and arranged to pivot from a rest position when said command is actuated, the rack part being provided with a probe arranged to abut against the second snail when the ringing command is actuated, a surprise jumper arranged to lean against the surprise under the effect of a spring to rotate the surprise on the first snail, and a surprise insulator device arranged to hold the surprise jumper away from the surprise when the piece to rack is in the rest position.

Rappelons que pratiquement toutes les pièces d'horlogerie capables de sonner les quarts et les minutes (ou les intervalles de cinq minutes) comportent une came escamotable appelée "surprise", qui est associée au limaçon des minutes (ou des cinq minutes). L'extrémité de chacune des quatre branches de ce limaçon doit être rétrécie pour permettre au palpeur des minutes d'atteindre l'échelon le plus proche du centre du limaçon, quand quatorze minutes doivent être sonnées. Il en résulte que l'échelon extérieur du limaçon, qui correspond à zéro minute de sonnerie, s'étend sur un angle inférieur à la valeur normale de 6° correspondant à la rotation du mobile de centre en une minute. Les quatre branches de la surprise servent à agrandir temporairement cet échelon au début de chaque quart d'heure. Le sautoir de surprise commande le pivotement de la surprise sur le limaçon en s'appuyant contre l'extrémité d'une des branches de la surprise. Dans les anciennes pièces d'horlogerie, cet appui était continu durant les dernières minutes d'un quart d'heure et les premières minutes du quart d'heure suivant. Le frottement du sautoir sur la surprise pendant cette durée produisait une usure notable des pièces en contact et tendait à ralentir le mouvement d'horlogerie.Remember that virtually all timepieces capable of ringing the quarters and minutes (or intervals of five minutes) include a retractable cam called "surprise", which is associated with the minute snail (or five minutes). The end of each of the four branches of this snail must be narrowed to allow the minute feeler to reach the nearest rung of the center of the snail, when fourteen minutes must be sounded. As a result, the outer rung of the snail, which corresponds to zero minute of ringing, extends at an angle less than the normal value of 6 ° corresponding to the rotation of the center wheel in one minute. The four branches of surprise serve to temporarily enlarge this step at the beginning of each quarter of an hour. The jumper of surprise controls the pivoting of the surprise on the snail by leaning against the end of one of the branches of surprise. In the old timepieces, this support was continuous during the last minutes of a quarter of an hour and the first minutes of the quarter of an hour following. The friction of the jumper on the surprise during this time produced a significant wear of the parts in contact and tended to slow the clockwork movement.

Pour pallier cet inconvénient, on a inventé il y a plus d'un siècle des dispositifs isolateurs de surprise, qui maintiennent le sautoir hors de prise de la surprise tant que la sonnerie des minutes n'est pas demandée. On trouve une description détaillée d'un exemple d'un isolateur de surprise aux pages 175 à 181 de la troisième édition du livre de F. Lecoultre intitulé "Les montres compliquées" et publié par Chs. Rohr & Cie SA, Bienne (Suisse) en 1985 (ISBN 2-88175-000-1 ). Ce dispositif est formé par un levier supplémentaire à deux branches, dont l'une s'appuie contre la commande de sonnerie lorsque celle-ci est au repos, pour que l'autre branche tienne pendant ce temps le sautoir de surprise à distance de la surprise, contre la force du ressort agissant sur le sautoir. La commande de sonnerie agit d'une part sur la pièce à crémaillère et d'autre part sur l'isolateur de surprise.To overcome this disadvantage, it was invented more than a century ago surprise insulator devices, which keep the jumper out of the surprise as long as the minute bell is not requested. There is a detailed description of an example of a surprise isolator at pages 175 to 181 of the third edition of F. Lecoultre's book entitled "Complicated watches" and published by Chs. Rohr & Cie SA, Bienne (Switzerland) in 1985 (ISBN 2-88175-000-1 ). This device is formed by an additional lever with two branches, one of which rests against the ringing command when it is at rest, so that the other branch during this time holds the surprise jumper at a distance from the surprise, against the strength of the spring acting on the saltire. The ringing control acts on the one hand on the rack piece and on the other hand on the surprise isolator.

Dans le brevet CH 11660 , il est décrit un isolateur de surprise comportant aussi un levier supplémentaire, mais agencé différemment. Dans ce cas, l'un des bras du levier isolateur prend appui sur la pièce à crémaillère pour que le levier garde une position telle que son autre bras retienne le sautoir de surprise. La commande de sonnerie agit sur le premier bras pour faire pivoter le levier de façon à pousser la pièce à crémaillère et libérer pendant ce temps le sautoir de surprise. Par contre, dans ce mécanisme le palpeur des heures n'est pas monté sur la pièce à crémaillère.In the patent CH 11660 , there is described a surprise insulator also having an additional lever, but arranged differently. In this case, one of the arm of the isolator lever is supported on the rack piece so that the lever maintains a position such that its other arm holds the surprise jumper. The ringer control acts on the first arm to pivot the lever so as to push the rack piece and release during this time the jumper surprise. By cons, in this mechanism the feeler hours is not mounted on the rack piece.

Dans les deux dispositifs susmentionnés, la fonction d'isolateur de surprise nécessite un levier supplémentaire relativement grand, qui est gênant dans un mécanisme déjà très compliqué. La présente invention permet d'éviter cet inconvénient grâce à une construction très simple et peu encombrante.In the two aforementioned devices, the surprise insulator function requires a relatively large additional lever, which is troublesome in an already very complicated mechanism. The present invention avoids this disadvantage through a very simple and compact construction.

A cet effet, l'invention concerne une pièce d'horlogerie à sonnerie du genre indiqué ci-dessus en préambule, caractérisée en ce que le dispositif isolateur de surprise comporte un élément saillant fixé à la pièce à crémaillère et agencé pour coopérer avec le sautoir de surprise pour écarter celui-ci de la surprise.For this purpose, the invention relates to a striking timepiece of the type indicated above in the preamble, characterized in that the surprise insulator device comprises a projecting element fixed to the rack piece and arranged to cooperate with the jumper of surprise to dismiss this one from the surprise.

Selon un mode de réalisation préféré de l'invention, ledit élément saillant, qui peut être formé par une goupille agencée pour s'appuyer contre un bord du sautoir de surprise, est disposé sur ledit palpeur, lequel est formé de préférence par un bras de la pièce à crémaillère qui croise le sautoir de surprise. Ledit palpeur peut être soit le palpeur des heures, agencé pour palper un limaçon des heures, soit un autre palpeur disposé sur une pièce à crémaillère et agencé pour palper par exemple un limaçon des quarts.According to a preferred embodiment of the invention, said projecting element, which may be formed by a pin arranged to bear against an edge of the jumper of surprise, is disposed on said feeler, which is preferably formed by an arm of the cogwheel piece that crosses the surprise jumper. Said probe may be either the feeler hours, arranged to feel a snail hour, or another probe disposed on a rack and arranged to feel for example a quarter snail.

D'autres caractéristiques et avantages de la présente invention apparaîtront dans la description suivante d'un mode de réalisation préféré, présenté à titre d'exemple non limitatif en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue en plan montrant le dispositif isolateur de surprise selon l'invention et les éléments auxquels il est associé dans le mécanisme de sonnerie d'une montre à grande sonnerie, dans une position de repos de ce mécanisme;
  • la figure 2 représente les éléments de la figure 1 dans une position où la commande de sonnerie vient d'être actionnée, et
  • la figure 3 représente les mêmes éléments que la figure 1, à une échelle agrandie.
Other features and advantages of the present invention will appear in the following description of a preferred embodiment, presented by way of non-limiting example with reference to the accompanying drawings, in which:
  • the figure 1 is a plan view showing the surprise isolator device according to the invention and the elements with which it is associated in the striking mechanism of a big-bell watch, in a rest position of this mechanism;
  • the figure 2 represents the elements of the figure 1 in a position where the ringing command has just been actuated, and
  • the figure 3 represents the same elements as the figure 1 on an enlarged scale.

Le mécanisme représenté dans les dessins représente un mobile de centre 1 entraîné par le mouvement d'horlogerie pour faire un tour par heure dans le sens de la flèche A. Le mobile 1 comporte une chaussée 2, un limaçon des quarts 3 et un limaçon des minutes 4 équipé d'une surprise 5. Chaque branche 4a, 4b, 4c et 4d du limaçon des minutes comporte quinze échelons, dont le premier 6a, situé le plus à l'extérieur et correspondant à la première minute d'un quart d'heure, est plus étroit que les autres. La surprise a pour fonction de prolonger cet échelon lorsqu'elle est dans sa position active 5a représentée en traits interrompus dans la figure 2. La position de la surprise 5 dessinée en traits continus est sa position escamotée. Elle est maintenue par un ressort de rappel (non représenté) s'appuyant sur le limaçon 4.The mechanism represented in the drawings represents a center mobile 1 driven by the watch movement to make one turn per hour in the direction of the arrow A. The mobile 1 comprises a roadway 2, a quarter snail 3 and a minute snail 4 equipped with a surprise 5. Each limb 4a, 4b, 4c and 4d of the minutes snail comprises fifteen steps, the first of which 6a, located the outermost and corresponding to the first minute of a quarter of an hour, is narrower than the others. The surprise has the function of extending this step when it is in its active position 5a shown in dashed lines in the figure 2 . The position of the surprise 5 drawn in continuous lines is its retracted position. It is held by a return spring (not shown) resting on the snail 4.

Un sautoir de surprise 8 est formé par un levier monté de manière pivotante en 9 et sollicité par un ressort 10 qui s'appuie contre une goupille 11 du sautoir 8 pour le pousser en direction de la surprise 5, le sautoir ayant un bec 12 en V qui présente un plan incliné 13 servant à faire pivoter la surprise 5 dans le sens de la flèche A contre la force du ressort de rappel susmentionné. Une butée fixe 15 retient le sautoir 8 quand il est avancé sans pouvoir s'appuyer contre la surprise.A surprise jumper 8 is formed by a lever pivotally mounted at 9 and biased by a spring 10 which rests against a pin 11 of the jumper 8 to push it towards the surprise 5, the jumper having a spout 12 in V which has an inclined plane 13 for rotating the surprise 5 in the direction of arrow A against the force of the aforementioned return spring. A fixed stop 15 holds the jumper 8 when it is advanced without being able to lean against the surprise.

Un limaçon des heures 16, formant une came à douze échelons 17, est fixé par une vis 18 à une étoile 19 qui est entraînée pas à pas par le mouvement d'horlogerie de façon à effectuer un tour en douze heures. Un sautoir 20 sollicité par un ressort 21 maintient l'étoile 19 dans chacune de ses douze positions.A snail 16 hours, forming a twelve-echelon cam 17, is fixed by a screw 18 to a star 19 which is driven step by step by the clockwork so as to perform a turn in twelve hours. A jumper 20 biased by a spring 21 maintains the star 19 in each of its twelve positions.

Une pièce à crémaillère 22 est montée de manière pivotante en 23 et comporte une goupille 24 contre laquelle s'appuie un ressort 25 qui tend à faire pivoter la pièce 22 dans le sens de la flèche B. Un bras de la pièce 22 constitue un palpeur des heures 26 dont l'extrémité 27 va buter contre l'un des échelons 17 du limaçon des heures 16 lorsque la pièce 22 pivote dans le sens de la flèche B. La pièce 22 comporte en outre une crémaillère 28 en arc de cercle, centrée en 23 et s'engrenant sur un pignon de crémaillère 29 monté de manière librement rotative sur un mobile de centre de sonnerie 30 pourvu d'un plateau d'entraînement 31. Le mobile de centre de sonnerie 30 comporte un pignon (non représenté) qui est en prise avec un barillet de sonnerie tendant à le faire tourner dans le sens de la flèche C. Le pignon de crémaillère 29 fait partie d'un mobile appelé tourelle, qui est rotatif autour du mobile 30 et comporte en outre un rochet à dents de loup 33 et un rochet des heures 34 destiné à actionner le marteau des heures (non représenté). Le plateau 31 porte un crochet 36 sollicité par un ressort 37 pour s'accrocher aux dents de loup du rochet 33 afin d'empêcher que la tourelle comprenant le pignon 29 ne tourne sous l'effet de la crémaillère 28 et du ressort 25.A rack piece 22 is pivotally mounted at 23 and has a pin 24 against which a spring 25 rests, which tends to pivot the piece 22 in the direction of the arrow B. An arm of the piece 22 constitutes a feeler hours 26 whose end 27 will abut against one of the rungs 17 of the hours snail 16 when the piece 22 pivots in the direction of the arrow B. The piece 22 further comprises a rack 28 in a circular arc, centered 23 and meshing on a rack pinion 29 mounted freely rotatably on a ring center mobile 30 provided with a drive plate 31. The ring center mobile 30 comprises a pinion (not shown) which is engaged with a ringing barrel tending to rotate in the direction of the arrow C. The rack pinion 29 is part of a mobile called turret, which is rotatable around the mobile 30 and further comprises a ratchet teeth of Wolf 33 and an hour ratchet 34 for operating the hour hammer (not shown). The plate 31 carries a hook 36 biased by a spring 37 to catch the wolf teeth of the ratchet 33 to prevent the turret comprising the pinion 29 from rotating under the effect of the rack 28 and the spring 25.

La commande de sonnerie ne sera pas décrite en détail ici. Il suffit de mentionner que pour mettre en action le mécanisme qui vient d'être décrit, elle comporte une roue dentée 40 montée sous le plateau 31 de façon à pouvoir pivoter dans une mesure limitée par rapport à celui-ci, la roue 40 ayant une goupille de commande 41 qui peut s'appuyer contre un pan incliné 42 du crochet 36 pour dégager celui-ci des dents du rochet 33.The ringing command will not be described in detail here. It suffices to mention that to activate the mechanism that has just been described, it comprises a toothed wheel 40 mounted under the plate 31 so as to be able to pivot to a limited extent with respect thereto, the wheel 40 having a control pin 41 which can bear against an inclined portion 42 of the hook 36 to disengage it from the teeth of the ratchet 33.

Dans la position de repos illustrée par les figures 1 et 3, le mobile de centre 1 tourne avec l'aiguille des minutes de la montre, tandis que l'étoile des heures 19 avance d'un pas par heure. Toutes les autres pièces représentées restent immobiles tant que la commande de sonnerie n'est pas actionnée, car le mobile de centre de sonnerie 30 est alors bloqué par la pièce des minutes (non représentée), qui bloque en fin de course le rouage de sonnerie.In the rest position illustrated by the figures 1 and 3 , the center mobile 1 rotates with the minute hand of the watch, while the hour star 19 advances one step per hour. All the other parts shown remain motionless until the ringing command is actuated, because the ring center mobile 30 is then blocked by the minute piece (not shown), which blocks at the end of the stroke the ring gear .

Le crochet 36 immobilise la tourelle formée par les éléments 29, 33 et 34, ce qui retient la pièce à crémaillère 22 à l'encontre de la force du ressort 25. Dans cette position de repos, une goupille 44, disposée en saillie sur le palpeur des heures 26 qui croise le sautoir de surprise 8, s'appuie contre un bord 45 du sautoir 8 et maintient celui-ci à l'écart de la trajectoire 46 des extrémités des bras de la surprise 5. Ainsi, le palpeur 26 et sa goupille 44 constituent un dispositif isolateur de surprise 47.The hook 36 immobilizes the turret formed by the elements 29, 33 and 34, which holds the rack piece 22 against the force of the spring 25. In this rest position, a pin 44, disposed projecting on the feeler of the hours 26 which crosses the jumper surprise 8, leans against an edge 45 of the jumper 8 and keeps it away from the trajectory 46 of the ends of the arm of the surprise 5. Thus, the probe 26 and its pin 44 is a surprise isolator device 47.

Lorsque la commande de sonnerie est actionnée, la roue dentée 40 tourne de quelques degrés dans le sens de la flèche C par rapport au plateau d'entraînement 31, de sorte que sa goupille 41 soulève le crochet 36 et libère la tourelle comprenant les éléments 29, 33 et 34. Cette tourelle est alors entraînée en rotation par la pièce à crémaillère 22 pivotant sous l'action du ressort 25. Dès le début de ce pivotement, la goupille 44 laisse le sautoir de surprise 8 pivoter en direction du mobile de centre 1. Si à ce moment-là l'une des branches 4a à 4d du limaçon des minutes 4 se trouve à proximité d'un des pans inclinés 12 et 13 du bec du sautoir 8, ce pan s'appuie contre la branche correspondante de la surprise 5 et met celle-ci dans la position appropriée, de manière connue. La pièce à crémaillère 22 continue de pivoter jusqu'à ce que l'extrémité 27 de son palpeur 26 bute contre le limaçon des heures 16, ce qui arrête l'action du rochet des heures 34. Ensuite, le mécanisme représenté est ramené à la position de repos de la figure 1 par l'action du barillet de sonnerie entraînant le mobile de centre de sonnerie 30. La goupille 44 de l'isolateur de surprise 47 soulève de nouveau le sautoir de surprise 8 et le tiendra à l'écart de la surprise 5 tant que la commande de sonnerie ne sera pas actionnée à nouveau.When the ringing command is actuated, the toothed wheel 40 rotates a few degrees in the direction of the arrow C relative to the drive plate 31, so that its pin 41 lifts the hook 36 and releases the turret comprising the elements 29. , 33 and 34. This turret is then rotated by the rack piece 22 pivoting under the action of the spring 25. From the beginning of this pivoting, the pin 44 leaves the jumper surprise 8 pivot towards the mobile center 1. If at that time one of the branches 4a to 4d of the minutes snail 4 is near one of the inclined faces 12 and 13 of the beak of the jumper 8, this pan rests against the corresponding branch of the surprise 5 and puts it in the appropriate position, in a known manner. The rack piece 22 continues to pivot until the end 27 of its feeler 26 abuts against the snail hours 16, which stops the action of the ratchet hours 34. Then, the mechanism shown is reduced to the rest position of the figure 1 by the action of the striking barrel driving the ringing center mobile 30. The pin 44 of the surprise isolator 47 raises the surprise jumper 8 again and will keep it away from the surprise 5 as long as the command ringer will not be pressed again.

La description qui précède montre que la présente invention permet de réaliser un dispositif isolateur de surprise sans aucune pièce mobile supplémentaire, simplement grâce à l'adjonction d'un élément saillant 44 sur une partie de la pièce à crémaillère 22 qui se déplace au voisinage d'un bord du sautoir de surprise 8. On notera que cet élément saillant n'est pas nécessairement disposé sur le palpeur des heures 26, mais pourrait se trouver sur un autre bras de la pièce 22 et présenter toute autre configuration apte à coopérer avec le sautoir 8, par exemple sous la forme d'un crochet ou d'un rebord plié à angle droit.The above description shows that the present invention makes it possible to produce a surprise insulator device without any additional moving parts, simply by adding a projecting element 44 to a part of the rack part 22 which moves in the vicinity of One edge of the jumper surprise 8. Note that this projecting element is not necessarily disposed on the feeler hours 26, but could be on another arm of the room 22 and present any another configuration adapted to cooperate with the jumper 8, for example in the form of a hook or a ridge bent at right angles.

Bien que l'exemple décrit ci-dessus se rapporte au cas d'une surprise associée au limaçon des minutes, il faut rappeler qu'un dispositif isolateur de surprise selon l'invention peut aussi bien coopérer avec une surprise associée à un autre limaçon, notamment un limaçon des quarts ou des cinq minutes.Although the example described above relates to the case of a surprise associated with the minute snail, it should be remembered that a surprise insulator device according to the invention can also cooperate with a surprise associated with another snail, especially a snail quarter or five minutes.

L'invention est utilisable dans toute pièce d'horlogerie pourvue d'une sonnerie, notamment une montre à répétition minutes ou à grande sonnerie.The invention can be used in any timepiece provided with a ring, including a minute repeater watch or large ring.
