Description

Arrière-plan de l'inventionBackground of the invention

La présente invention est relative à un dispositif d'arrêt pendant la mise à l'heure d'une montre équipée d'un tourbillon, ce tourbillon comportant une cage rotative à l'intérieur de laquelle un balancier oscille autour d'un axe de rotation de la cage, ce dispositif comprenant des moyens commandés manuellement pour bloquer le balancier dans sa zone périphérique.The present invention relates to a stop device during the time setting of a watch equipped with a tourbillon, this tourbillon comprising a rotating cage inside which a balance oscillates about an axis of rotation. of the cage, this device comprising manually controlled means for locking the balance in its peripheral zone.

Un tel dispositif, parfois appelé "stop-seconde", a déjà été proposé pour arrêter l'oscillation du balancier dans la cage du tourbillon pendant la mise à l'heure, dans n'importe quelle position de la cage, à partir de la tige de commande de la montre afin de démarrer le mouvement à un instant précis, par exemple exactement à l'heure indiquée par les aiguilles de la montre.Such a device, sometimes called "stop-second", has already been proposed to stop the oscillation of the balance in the vortex cage during the time setting, in any position of the cage, from the control rod of the watch to start the movement at a specific time, for example exactly at the time indicated by the hands of the watch.

Une description de ce dispositif est donnée dans le document DE 101 60 287 A1 repris par la demande internationale WO 03/048871. De façon bien connue dans l'état de la technique, le tourbillon comprend une cage mobile qui porte tous les organes de l'échappement et, en son centre, l'organe régulateur comprenant le balancier. Le pignon d'échappement tourne autour de la roue des secondes qui est fixe. La cage fait un tour par minute et annule en tournant les écarts de marche dans les positions verticales. Pour arrêter le mouvement, le document cité propose un ressort mobile à deux branches élastiques terminées chacune par un patin pouvant aller s'appuyer élastiquement contre la périphérie du balancier pour l'arrêter. Ce ressort mobile est commandé par la tige de mise à l'heure, cette dernière étant à son tour commandée manuellement.A description of this device is given in the document DE 101 60 287 A1 reproduced by the international application WO 03/048871. In a manner well known in the state of the art, the vortex comprises a movable cage which carries all the bodies of the exhaust and, in its center, the regulating member comprising the balance. The escape gear rotates around the seconds wheel which is fixed. The cage makes one revolution per minute and cancels by turning the deviations in the vertical positions. To stop the movement, the cited document proposes a movable spring with two elastic branches each terminated by a pad that can bear resiliently against the periphery of the beam to stop it. This mobile spring is controlled by the time setting rod, the latter being in turn manually controlled.

Ce dispositif présente plusieurs inconvénients. Celui d'abord de la réalisation du ressort mobile qui est compliquée, ce ressort, vu sa grande longueur, demandant en outre un réglage difficile à réaliser. Un autre inconvénient réside dans le fait qu'un ressort d'une telle longueur peut facilement se déformer sous l'effet d'un choc appliqué à la montre et bloquer ainsi intempestivement le balancier. Enfin on mentionnera que dans l'horlogerie de très haut de gamme l'emploi du ressort-fil ou ressort-lame est généralement proscrit, car inesthétique et présentant des solutions convenant mal à un objet de haute technicité.This device has several disadvantages. That first of the realization of the mobile spring is complicated, this spring, given its great length, also requiring a setting difficult to achieve. Another disadvantage lies in the fact that a spring of such a length can easily be deformed under the effect of a shock applied to the watch and thus inadvertently block the balance. Finally, it should be mentioned that in the high end of the watchmaking industry the use of the wire spring or leaf spring is generally proscribed, since it is unsightly and has solutions that are not suitable for an object of high technicality.

Résumé de l'inventionSummary of the invention

Pour pallier les inconvénients cités ci-dessus, la présente invention, outre qu'elle obéit à la définition générique posée au premier paragraphe de cette description, est remarquable en ce que les moyens pour bloquer le balancier comportent des éléments mobiles montés sur la cage du tourbillon et susceptibles d'entrer en contact avec la périphérie du balancier pour le bloquer quand une action est exercée sur l'un au moins des éléments mobiles par un élément disposé à l'extérieur de la cage et commandé manuellement.To overcome the drawbacks mentioned above, the present invention, besides it obeys the generic definition in the first paragraph of this description, is remarkable in that the means for locking the pendulum comprise movable elements mounted on the tourbillon cage and likely to come into contact with the periphery of the balance to block when an action is exerted on at least one of movable elements by an element disposed outside the cage and controlled manually.

Description détaillée d'un mode de réalisationDetailed description of an embodiment

Le tourbillon 1 montré sur les figures 1 et 2 comprend de manière habituelle une cage rotative 2 à trois piliers 4. A l'intérieur de la cage se trouvent le balancier 3 associé à un spiral et les organes de l'échappement, notamment la roue d'échappement 5, le pignon d'échappement 6 et l'ancre 7. Une aiguille des secondes est représentée en 8. Le balancier 3 oscille en rotation à l'intérieur de la cage 2 autour de l'axe de rotation 10 de la cage. La périphérie du balancier 3 comporte une serge 12 munie de vis 13. Les figures 1 à 4 montrent que sur la périphérie du balancier 3 agissent des moyens commandés manuellement pour bloquer ledit balancier, ces moyens consistant, non pas à mettre en oeuvre un ressort mobile à deux branches à l'extérieur à la cage du tourbillon comme dans le document DE 101 60 287 cité plus haut, mais à utiliser des éléments mobiles 14, 15 et 16 montés sur la cage 2 et susceptibles d'entrer en contact avec la périphérie du balancier 3 pour le bloquer quand une action est exercée sur l'un au moins desdits éléments mobiles par un élément 17, ici un sabot coulissant, disposé à l'extérieur de la cage 2 et commandé manuellement.The vortex 1 shown in FIGS. 1 and 2 comprises, in the usual manner, a rotary cage 2 with three pillars 4. Inside the cage there is the balance 3 associated with a hairspring and the bodies of the exhaust, in particular the wheel. 5, the exhaust pinion 6 and the anchor 7. A second hand is shown in 8. The rocker 3 oscillates in rotation inside the cage 2 about the axis of rotation 10 of the cage. The periphery of the balance 3 comprises a serge 12 provided with screws 13. FIGS. 1 to 4 show that on the periphery of the balance 3 act manually controlled means for locking said balance, these means consisting, not in implementing a movable spring with two branches outside the vortex cage as in DE 101 60 287 cited above, but to use movable elements 14, 15 and 16 mounted on the cage 2 and may come into contact with the periphery balance 3 to block when an action is exerted on at least one of said movable elements by an element 17, here a sliding shoe disposed outside the cage 2 and manually controlled.

On va examiner maintenant une manière de réaliser les éléments mobiles dont il a été question ci-dessus et comment ces éléments mobiles peuvent être commandés manuellement par le porteur de la montre.We will now examine a way to achieve the moving elements discussed above and how these movable elements can be manually controlled by the wearer of the watch.

Si l'on considère particulièrement la figure 1 qui présente le tourbillon 1 dont une partie est montrée en éclaté, on voit que chacun desdits éléments mobiles est un levier 14, 15 et 16 monté sur la cage 2. Chaque levier 14, 15 et 16 présente un bord extérieur 18, 19 et 20 en forme d'arc de cercle centré sensiblement sur l'axe de rotation 10 de la cage 2. La première extrémité 21 de chaque levier est montée pivotante sur la cage et sa seconde extrémité 22 porte un patin 23, 24 et 25 susceptible de bloquer le balancier 3. Comme on le voit sur la figure 4, ce blocage intervient quand le sabot 17, commandé par une tige de mise à l'heure 26, exerce une pression sur le levier 14 et plus généralement sur au moins un des leviers 14, 15 et 16. Les figures 1 et 4 montrent encore que chacun de ces leviers est rappelé par un ressort de rappel 28, 29 et 30 monté sur la cage 2, quand le sabot 17 cesse d'exercer son appui sur le levier.1, which presents the vortex 1, a portion of which is shown in an exploded view, it can be seen that each of said movable elements is a lever 14, 15 and 16 mounted on the cage 2. Each lever 14, 15 and 16 has an outer edge 18, 19 and 20 in the form of a circular arc centered substantially on the axis of rotation 10 of the cage 2. The first end 21 of each lever is pivotally mounted on the cage and its second end 22 carries a skid 23, 24 and 25 capable of blocking the balance 3. As can be seen in FIG. 4, this blocking occurs when the shoe 17, controlled by a time-setting rod 26, exerts a pressure on the lever 14 and more generally on at least one of the levers 14, 15 and 16. Figures 1 and 4 show that each of these levers is recalled by a return spring 28, 29 and 30 mounted on the cage 2, when the shoe 17 ceases to exert support on the lever.

Le mode de réalisation présenté sur les figures comporte trois leviers 14, 15 et 16 montés sur la cage 2 et entourant la totalité de cette cage. Pour ce faire, dans une zone périphérique de ladite cage 2 sont fixés trois pieds à vis 32 appelés aussi pieds-vis, répartis à égale distance les uns des autres et dont un seul est visible sur la figure 1, les autres étant masqués par une tête de vis 33 de large dimension vissée dans le pied-vis. Sur chacun des pieds-vis est montée pivotante une douille 35, 36 et 37. Comme on le voit clairement sur la figure 1, sur cette douille sont chassés un premier anneau 38, 39 et 40 formant la première extrémité 21 du levier 14, 15 et 16 et un second anneau 42, 43 et 44 formant une première extrémité 45 du ressort de rappel respectif 28, 29 et 30. La figure 2 montre que la seconde extrémité 46 du ressort de rappel 28 s'appuie contre un élément supporté par la cage, en l'occurrence le second anneau 43 du ressort de rappel suivant 29. Il en va de même pour les ressorts de rappel 29 et 30. Ainsi par exemple, quand le sabot 17 exerce une pression sur le levier 14 (situation représentée à la figure 4), le ressort de rappel 28 se tend et sa seconde extrémité 46 glisse sur l'anneau 43 du ressort de rappel 29.The embodiment shown in the figures comprises three levers 14, 15 and 16 mounted on the cage 2 and surrounding the entire cage. To do this, in a peripheral zone of said cage 2 are fixed three screw feet 32 also called screw feet, distributed at equal distance from each other and only one of which is visible in FIG. 1, the others being masked by a screw head 33 of large dimension screwed into the foot-screw. On each of the screw-feet is pivotally mounted a sleeve 35, 36 and 37. As can be seen clearly in Figure 1, on this sleeve are driven a first ring 38, 39 and 40 forming the first end 21 of the lever 14, 15 and 16 and a second ring 42, 43 and 44 forming a first end 45 of the respective return spring 28, 29 and 30. FIG. 2 shows that the second end 46 of the return spring 28 bears against an element supported by the cage, in this case the second ring 43 of the next return spring 29. The same applies to the return springs 29 and 30. For example, when the shoe 17 exerts a pressure on the lever 14 (situation shown in FIG. 4), the return spring 28 is tensioned and its second end 46 slides on the ring 43 of the return spring 29.

On mentionnera que dans le mode de réalisation représenté sur les figures, la position de repos de chacun des leviers 14, 15 et 16 est définie par un arrêt 47, 48 et 49 qui fait partie de la cage 2, comme cela se voit sur les figures 1 et 2. On voit en effet que le patin 23, 24 et 25 du levier 14, 15 et 16 va buter contre cet arrêt.It will be mentioned that in the embodiment shown in the figures, the rest position of each of the levers 14, 15 and 16 is defined by a stop 47, 48 and 49 which forms part of the cage 2, as can be seen in the Figures 1 and 2. It is seen that the shoe 23, 24 and 25 of the lever 14, 15 and 16 will abut against this stop.

On va expliquer maintenant comment le sabot 17 est commandé à partir de la tige de mise à l'heure 26. Les figures 3 et 4 sont des vues en plan d'une partie de la montre dans laquelle est installé le tourbillon 1. On a expliqué ci-dessus comment le balancier 3 équipant le tourbillon peut être bloqué par le sabot 17. Comme le montrent les figures 3 et 4, ce sabot 17 est pourvu d'une queue 50 apte à glisser dans un fraisage 51 que comporte la platine de la montre. L'extrémité de la queue 50 est attachée à une bielle 52 commandée par une tirette 53, commandée à son tour par la tige de mise à l'heure 26. La tirette 53 agit sur un sautoir 54 qui indexe les positions poussée et tirée de la tige 26.We will now explain how the shoe 17 is controlled from the time-setting rod 26. FIGS. 3 and 4 are plan views of a part of the watch in which the tourbillon 1 is installed. explained above how the 3 balance equipping the vortex can be blocked by the shoe 17. As shown in Figures 3 and 4, the shoe 17 is provided with a tail 50 adapted to slide in a milling 51 that includes the watch plate. The end of the tail 50 is attached to a rod 52 controlled by a pull rod 53, in turn controlled by the time setting rod 26. The pull rod 53 acts on a jumper 54 which indexes the push and pull positions of the stem 26.

La figure 3 montre la tige 26 en position poussée. C'est la position de repos pour laquelle la montre peut être remontée. Dans cette position, le sabot 17 est espacé du tourbillon 1 et du balancier de celui-ci.Figure 3 shows the rod 26 in the pushed position. This is the rest position for which the watch can be reassembled. In this position, the shoe 17 is spaced from the vortex 1 and the balance thereof.

La figure 4 montre la tige 26 en position tirée. C'est la position de mise à l'heure de la montre, pour laquelle les aiguilles d'heure et de minute peuvent être réglées en tournant une couronne coiffant la tige 26 à l'extérieur de la boîte de la montre. Lorsque la tige 26 est tirée, le sabot 17 est déplacé en direction du tourbillon et exerce une pression sur au moins un des leviers 14, 15 et 16, sur le levier 14 dans cet exemple. Le patin 23 monté sur le levier 14 bloque alors instantanément le balancier 3 par friction en s'appuyant radialement contre un élément du balancier, en l'occurrence contre une des vis 13 montées sur la serge 12. Ce patin pourrait s'appuyer contre la serge 12 dans certains cas.Figure 4 shows the rod 26 in the pulled position. This is the time setting position of the watch, for which the hour and minute hands can be adjusted by turning a crown covering the stem 26 on the outside of the watch case. When the rod 26 is pulled, the shoe 17 is moved towards the vortex and exerts pressure on at least one of the levers 14, 15 and 16 on the lever 14 in this example. The shoe 23 mounted on the lever 14 then instantly blocks the rocker 3 by friction by pressing radially against an element of the rocker, in this case against one of the screws 13 mounted on the serge 12. This pad could lean against the serge 12 in some cases.

On notera que les bords extérieurs 18, 19 et 20 des leviers 14, 15 et 16 sont situés au-dessus des piliers 4 de la cage 2 (voir figures 1 et 2). De cette façon, le sabot 17 peut agir sur lesdits leviers sans interférer avec les piliers de cage qui circulent, on l'a vu plus haut, à raison d'un tour par minute. On notera encore que les patins 23, 24 et 25 présentent une certaine élasticité de sorte que le balancier, lors de son arrêt, n'est pas sollicité outre mesure. On notera enfin que le sabot 17 présente, en regard des bords extérieurs 18, 19 et 20 des leviers, une face concave 56 agencée pour s'appuyer contre lesdits bords extérieurs. Cette face concave présente une longueur plus grande que l'intervalle 57 (figure 3) séparant les bords extérieurs de deux leviers successifs. De cette manière, la face concave 56 du sabot 17 peut agir sur un ou deux leviers, quelle que soit la position angulaire de la cage du tourbillon.Note that the outer edges 18, 19 and 20 of the levers 14, 15 and 16 are located above the pillars 4 of the cage 2 (see Figures 1 and 2). In this way, the shoe 17 can act on said levers without interfering with the moving cage pillars, as we saw above, at a rate of one revolution per minute. It will also be noted that the shoes 23, 24 and 25 have a certain elasticity so that the balance, when it is stopped, is not unduly stressed. Note finally that the shoe 17 has, facing the outer edges 18, 19 and 20 of the levers, a concave face 56 arranged to bear against said outer edges. This concave face has a length greater than the interval 57 (Figure 3) separating the outer edges of two successive levers. In this way, the concave face 56 of the shoe 17 can act on one or two levers, regardless of the angular position of the tourbillon cage.

La description qui vient d'être donnée du dispositif d'arrêt selon la présente invention montre bien qu'on a affaire ici à une réalisation de haute technicité faisant appel à des solutions convenant parfaitement bien à une horlogerie de haut de gamme. En effet, le ressort-fil ou ressort-lame agissant directement sur le balancier a été évité, mettant ainsi de côté les inconvénients qu'il amène et qui ont été énumérés dans le préambule de cette description.The description that has just been given of the stop device according to the present invention shows that we are dealing here with a high-tech embodiment using solutions that are perfectly suited to a high-end watchmaking. Indeed, the wire spring or leaf spring acting directly on the beam has been avoided, thus setting aside the drawbacks it brings and which have been listed in the preamble of this description.
