Definitions
- the subject of the present invention is a mechanism for correcting the attitude of a balance-spiral regulating device of a mechanical timepiece, in order to reduce, or even cancel, the gait deviations resulting from the changes in the spatial orientation of said device. setting, as is the case for a wristwatch or a pocket watch.
- the patent CH 693 047 discloses a "vortex" mechanism, whose cage is pivoted on two perpendicular axes to make it take a large number of positions, the balance sprung axis then being centered on a pivot axis, the assembly always being driven by a intermediate wheel receiving its driving energy from the barrel.
- the movements imposed on the cage can theoretically and statistically compensate for the deviations of step, but that it does not exclude, when the watch is worn on the wrist, that the regulating device remains sufficiently long in a given position for cause a big delay, or a strong advance. In other words there is no interaction between the permanent rotational motion imposed on the vortex and the spatial orientation of the watch, and therefore its regulating device, when worn on the wrist.
- the invention therefore relates to a trim correction mechanism of the regulating device, that is to say a mechanism that maintains the assortment, escape wheel, anchor, plate and more particularly the balance-spiral in a plane essentially fixed, whether horizontal, vertical or with an intermediate slope, and this regardless of the movements imposed on the watch by wearing on the wrist, without using the energy of the drive member, namely the barrel.
- the barrel no longer biased to provide energy, but it can instead receive a correction mechanism of the plate, as will be explained later.
- the subject of the invention is a mechanism for correcting the attitude of a platform supporting a regulating device of a mechanical timepiece including in particular a spiral balance driven by an escape wheel, in which said platform is suspended in a cage around an axis A 1 being secured to a counterweight, in free rotation about the axis A 1 , maintaining said platform in a substantially fixed plane when the cage is inclined in a plane perpendicular to the axis A 1 .
- Said escape wheel is engaged with a driving wheel secured to the axis A 1 and driven in rotation by the barrel wheel indirectly by a driving kinematic chain, as well as by a gear train forming a corrective kinematic chain in engagement with a wheel secured to the counterweight to rotate said driving wheel in the same direction and with the same speed as the counterweight.
- the driving wheel and the driving and corrective kinematic chains are connected by a first differential device.
- the cage is itself pivoted in a frame integral with the watch case along an axis A 2 situated in a plane perpendicular to the axis A 1 , the transmission of the torque from the barrel wheel to the driving wheel being effected indirectly. by an intermediate gear constituting the output of a second differential device engaged with the barrel wheel and with a corrective kinematic chain meshing with a toothed wheel secured to the cage.
- the counterweight or the cage forming a counterweight positions the platform , and therefore the entire regulating device, in a constant position imposed by the counterweight or the counterweight assembly, the parasitic couples being annihilated by the kinematic correction chains.
- the mechanism is mounted in the housing of a wristwatch with mechanical winding and it is desired to maintain the regulating device in a substantially horizontal position.
- the figure 1 is a schematic overview comprising a cage 10 in which is disposed a platform 3 supporting the usual assortment of a regulating device shown in the figures only by the escape wheel 5, the sprung balance and the others elements of the set not being represented.
- platform is meant a rigid support, usually but not necessarily flat.
- the platform 3 is fixed on the upper part of a counterweight 9, constituted for example by a mass of brass.
- the counterweight 9 is mounted for free rotation on an axis A 1 pivoted between two panels 10a, 10b of the cage 10.
- the counterweight 9 keeps the platform 3 in a horizontal position, and thereby the entire assortment, including the sprung balance and the escape wheel 5 in the example shown.
- FIG. figure 2 which is an enlarged partial view
- the torque is transmitted through the axis A 1 to a driving wheel 6 engaged with the escape wheel 5 by a bevel gear.
- a spurious torque is created on the escapement wheel 5 due to the rotation of the counterweight 9 about the axis A 1 .
- the mechanism is provided to compensate for this parasitic torque as explained with reference to the corrective kinematic chain shown in FIG. figure 3 .
- a wheel 8 integral with the counterweight 9 meshes with a wheel 12, mounted on an axis A ' 1 pivoted between the panels 10a, 10b of the cage 10 and parallel to the axis A 1 , said axis A' 1 supporting at its other end a wheel 14 which itself meshes with a wheel 18 integral with the axis A 1 and can thus transmit the torque to the escape wheel 5 not via the driving wheel 6.
- the number of wheels and the gear ratios of the chain thus formed are provided so that the driving wheel 6 has the same speed and the same direction of rotation as the wheel 8.
- the dummy wheel 4 is replaced by a differential 11 having a PTO for the driving kinematic chain, a PTO for the corrective kinematic chain and an output engaged with the driving wheel 6.
- the differential 11 shown is composed of satellites with bevel gears. It comprises a carrier 15 provided on its outer wall with a toothed ring 15a in direct or indirect engagement with the barrel wheel 7.
- the satellite carrier 15 comprises a first satellite 17 with conical teeth rotated free rotation at a point of rotation. the inner wall of the planet carrier 15.
- a second conical satellite 19a meshing with the first satellite 17 is pivoted on an axis in the extension of the axis A 1 , crossing a bottom of the planet carrier 15 and supporting the wheel 18 of the correction kinematic chain.
- the three bevel gears 17, 19a, 19b have the same diameter and transmit without modification the speeds of the drive and correction chains.
- the cage 10 is rotatably mounted between two pivots 23a, 23b in bridges and / or plates 30a, 30b, 30c of the case 30 of the wristwatch along an axis A 2 perpendicular to the general plane of the watch and therefore to the axis A 1 .
- the lower plate 10c has a pivot 23a pivoted in a frame member 30c, and opposite a pivot 23b pivoted in another element 30a of the frame.
- the cage 10 and the elements it contains act as a second counterweight to maintain the platform 3 in a horizontal position when the watch is inclined by the movement of the wrist in a plane perpendicular to the axis A 2 . Since the largest mass of this second counterweight is the counterweight 9 itself, the axis A 2 will preferably be non-secant with the axis A 1 to increase the moment causing the rotation of the cage 10.
- the differential 21 is composed of mobiles 25a, 27, 29a and 29b similar to those already described for the first differential 11 and it will therefore not be described further. It comprises a driving force output of the barrel 7a formed by a conical gear 13 which meshes with the conical toothing 15a of the planet carrier 15 of the first differential 11 to transmit the driving torque to the driving wheel 6.
- the second differential 21 comprises an input connected to the wheel 20 of the cage 10 by a gear train 22, 24, 26, 28 designed with the same constraints as before and which will therefore not be described further.
- the mechanism which has just been described makes it possible to keep the platform 3 horizontal regardless of the inclinations imposed on the watch in planes perpendicular to the axes A 1 or A 2 , and obviously according to any other intermediate inclination, so that the balance-sprung adjusting device is no longer influenced by the spatial orientation of the watch.
- the movement of the cage 10 is comparable to that of an oscillating mass and it is possible to provide that the toothing of the wheel 20 of the cage 10 meshes with an automatic winding block 40, which makes it possible to "recover" the energy along the axis A 2 .
- a third differential 31 also comprising mobiles 37, 39a, 39b comparable to those described above, the carrier 35 from the material material with the upper plate 10c.
- the first PTO along the axis A 1 is effected by means of an additional wheel 34 integral with said axis A 1 and meshing by a bevel gear with a wheel 36 driving the satellite 39a and the intermediate satellite 37.
- the second take force along the axis A 2 is constituted by the satellite carrier 35 integral with the upper plate 10c of the cage 10.
- the output of the differential 31 is constituted by a wheel 38 secured to the satellite 39b and meshing with the automatic winding block 40
- This third differential 31 differs from the two preceding 11, 21, only in that it is crossed by an axis 33 connecting the intermediate wheel 13 in engagement with the first differential 11 and the satellite 29b of the second differential 21.

Description
La présente invention a pour objet un mécanisme de correction d'assiette d'un dispositif réglant balancier-spiral d'une pièce d'horlogerie mécanique, afin de réduire, voire annuler, les écarts de marche résultant des changements d'orientation spatiale dudit dispositif réglant, comme c'est le cas pour une montre-bracelet ou pour une montre de poche.The subject of the present invention is a mechanism for correcting the attitude of a balance-spiral regulating device of a mechanical timepiece, in order to reduce, or even cancel, the gait deviations resulting from the changes in the spatial orientation of said device. setting, as is the case for a wristwatch or a pocket watch.
On connaît déjà des systèmes réglants dits "tournants", dans lesquels le dispositif réglant est monté dans une cage tournante suspendue, pouvant comporter un ou deux axes de pivotement, ladite cage étant entraînée en permanence, par exemple par la roue de moyenne. Le brevet
Le brevet
Il existe également des mécanismes "tourbillon" dans lesquels il est prévu trois axes de pivotement, comme décrit par exemple dans le brevet
Dans tous les cas on observera que la rotation de la cage incorporant le dispositif réglant est un mouvement forcé. En d'autres termes, cette rotation de la cage exige un supplément d'énergie de la part de l'organe moteur, à savoir le barillet, même lorsque cela n'est pas nécessaire, par exemple lorsque la pièce d'horlogerie est une montre-bracelet au repos, par exemple en étant posée sur une table pour la nuit.In all cases it will be observed that the rotation of the cage incorporating the regulating device is a forced movement. In other words, this rotation of the cage requires additional energy from the motor member, namely the barrel, even when it is not necessary, for example when the timepiece is a wristwatch at rest, for example by being placed on a table for the night.
De plus on observera que les mouvements imposés à la cage peuvent théoriquement et statistiquement compenser les écarts de marche, mais qu'il n'exclut nullement, lorsque la montre est portée au poignet, que le dispositif réglant reste suffisamment longtemps dans une position donnée pour provoquer un fort retard, ou une forte avance. En d'autres termes il n'existe aucune interaction entre le mouvement de rotation permanent imposé au tourbillon et l'orientation spatiale de la montre, et donc de son dispositif réglant, lorsqu'elle est portée au poignet.Moreover, it will be observed that the movements imposed on the cage can theoretically and statistically compensate for the deviations of step, but that it does not exclude, when the watch is worn on the wrist, that the regulating device remains sufficiently long in a given position for cause a big delay, or a strong advance. In other words there is no interaction between the permanent rotational motion imposed on the vortex and the spatial orientation of the watch, and therefore its regulating device, when worn on the wrist.
L'invention a donc pour objet un mécanisme de correction d'assiette du dispositif réglant, c'est à dire un mécanisme qui maintienne l'assortiment, roue d'échappement, ancre, plateau et plus particulièrement le balancier-spiral dans un plan essentiellement fixe, qu'il soit horizontal, vertical ou avec une inclinaison intermédiaire, et ceci quels que soient les mouvements imposés à la montre par le porté au poignet, sans faire appel à l'énergie de l'organe moteur, à savoir le barillet.The invention therefore relates to a trim correction mechanism of the regulating device, that is to say a mechanism that maintains the assortment, escape wheel, anchor, plate and more particularly the balance-spiral in a plane essentially fixed, whether horizontal, vertical or with an intermediate slope, and this regardless of the movements imposed on the watch by wearing on the wrist, without using the energy of the drive member, namely the barrel.
Selon un autre aspect de l'invention, non seulement le barillet n'est plus sollicité pour fournir de l'énergie, mais il peut au contraire en recevoir du mécanisme de correction de l'assiette, comme cela sera expliqué par la suite.According to another aspect of the invention, not only is the barrel no longer biased to provide energy, but it can instead receive a correction mechanism of the plate, as will be explained later.
A cet effet l'invention a pour objet un mécanisme de correction d'assiette d'une plate-forme supportant un dispositif réglant d'une pièce d'horlogerie mécanique comprenant notamment un balancier spiral entraîné par une roue d'échappement, dans laquelle ladite plate-forme est suspendue dans une cage autour d'un axe A1 en étant solidaire d'un contrepoids, en libre rotation autour de l'axe A1, maintenant ladite plateforme dans un plan essentiellement fixe lorsque la cage est inclinée dans un plan perpendiculaire à l'axe A1. Ladite roue d'échappement est en prise avec une roue entraîneuse solidaire de l'axe A1 et entraînée en rotation par la roue de barillet indirectement par une chaîne cinématique motrice, ainsi que par un train d'engrenages formant une chaîne cinématique correctrice en prise avec une roue solidaire du contrepoids pour faire tourner ladite roue entraîneuse dans le même sens et avec la même vitesse que le contrepoids.For this purpose, the subject of the invention is a mechanism for correcting the attitude of a platform supporting a regulating device of a mechanical timepiece including in particular a spiral balance driven by an escape wheel, in which said platform is suspended in a cage around an axis A 1 being secured to a counterweight, in free rotation about the axis A 1 , maintaining said platform in a substantially fixed plane when the cage is inclined in a plane perpendicular to the axis A 1 . Said escape wheel is engaged with a driving wheel secured to the axis A 1 and driven in rotation by the barrel wheel indirectly by a driving kinematic chain, as well as by a gear train forming a corrective kinematic chain in engagement with a wheel secured to the counterweight to rotate said driving wheel in the same direction and with the same speed as the counterweight.
La roue entraîneuse et les chaînes cinématiques motrice et correctrice sont reliées par un premier dispositif différentiel.The driving wheel and the driving and corrective kinematic chains are connected by a first differential device.
La cage est elle-même pivotée dans un bâti solidaire de la boîte de montre selon un axe A2 situé dans un plan perpendiculaire à l'axe A1, la transmission du couple de la roue de barillet à la roue entraîneuse s'effectuant indirectement par un pignon intermédiaire constituant la sortie d'un deuxième dispositif différentiel en prise avec la roue de barillet et avec une chaîne cinématique correctrice en prise avec une roue dentée solidaire de la cage.The cage is itself pivoted in a frame integral with the watch case along an axis A 2 situated in a plane perpendicular to the axis A 1 , the transmission of the torque from the barrel wheel to the driving wheel being effected indirectly. by an intermediate gear constituting the output of a second differential device engaged with the barrel wheel and with a corrective kinematic chain meshing with a toothed wheel secured to the cage.
Ainsi quelles que soient les inclinaisons qu'on donne à la montre dans une direction perpendiculaire à l'axe A1, ou à l'axe A2, ou à une direction intermédiaire, le contrepoids ou la cage formant contrepoids positionne la plate-forme, et donc l'ensemble du dispositif réglant, dans une position constante imposée par le contrepoids ou l'ensemble formant contrepoids, les couples parasites étant annihilés par les chaînes cinématiques correctrices.Thus regardless of the inclinations given to the watch in a direction perpendicular to the axis A 1 , or to the axis A 2 , or to an intermediate direction, the counterweight or the cage forming a counterweight positions the platform , and therefore the entire regulating device, in a constant position imposed by the counterweight or the counterweight assembly, the parasitic couples being annihilated by the kinematic correction chains.

Dans la description qui suit, on considère que le mécanisme est monté dans le boîtier d'une montre-bracelet à remontage mécanique et qu'on souhaite maintenir le dispositif réglant dans une position essentiellement horizontale.In the following description, it is considered that the mechanism is mounted in the housing of a wristwatch with mechanical winding and it is desired to maintain the regulating device in a substantially horizontal position.
Le principe du mécanisme de correction d'assiette est d'abord décrit en se référant aux
La
En se référant maintenant plus particulièrement à la chaîne cinématique motrice représentée à la
Concernant la chaîne correctrice, une roue 8 solidaire du contrepoids 9 engrène avec une roue 12, montée sur un axe A'1 pivoté entre les panneaux 10a, 10b de la cage 10 et parallèle à l'axe A1, ledit axe A'1 supportant à son autre extrémité une roue 14 qui engrène elle-même avec une roue 18 solidaire de l'axe A1 et pouvant donc transmettre le couple à la roue d'échappement 5 pas l'intermédiaire de la roue entraîneuse 6.Concerning the corrective chain, a
Le nombre de roues et les rapports d'engrenage de la chaîne ainsi formée sont prévus de sorte que la roue entraîneuse 6 ait la même vitesse et le même sens de rotation que la roue 8.The number of wheels and the gear ratios of the chain thus formed are provided so that the
Dans l'exemple représenté on a un nombre impair de roues indépendantes 8, 12/14, 18, et les roues 8, 18 d'une part et les roues 12, 14 d'autre part ayant respectivement le même nombre de dents, la condition énoncée ci-dessus est remplie, mais d'autres choix sont évidemment possibles. Ainsi le dispositif qui vient d'être décrit permet de maintenir la roue d'échappement 5 immobile lorsque le contrepoids 9 subit une rotation autour de l'axe A1, en supposant bien sûr qu'aucun couple n'est exercé par la chaîne cinématique motrice.In the example shown there is an odd number of
En se référant maintenant à la
Comme on le voit, la roue fictive 4 est remplacée par un différentiel 11 ayant une prise de force pour la chaîne cinématique motrice, une prise de force pour la chaîne cinématique correctrice et une sortie en prise avec la roue entraîneuse 6. Le différentiel 11 représenté est composé de satellites à engrenages coniques. Il comprend un porte-satellite 15 pourvu sur sa paroi extérieure d'un anneau denté 15a en prise directe ou indirecte avec la roue de barillet 7. Le porte satellite 15 comprend un premier satellite 17 à denture conique pivoté à libre rotation en un point de la paroi intérieure du porte-satellite 15. Un deuxième satellite conique 19a engrenant avec le premier satellite 17 est pivoté sur un axe dans le prolongement de l'axe A1, traversant un fond du porte-satellite 15 et supportant la roue 18 de la chaîne cinématique correctrice. Un troisième satellite conique 19b monté sur l'axe A1, et engrenant avec le premier satellite 17, entraîne avec la roue entraîneuse en fonction des couples reçus des chaînes cinématiques motrice et correctrice. Etant donné que le différentiel 11 représenté introduit une inversion du sens de rotation il est nécessaire de prévoir, sur la chaîne cinématique allant de la roue 8 du contrepoids 9 à la roue entraîneuse 6, un pignon inverseur à double denture désigné par la référence 16, les nombres de dents des roues intermédiaires étant prévus pour que la roue menante 8 et la roue menée 6 aient la même vitesse et le même sens de rotation. Il est bien entendu possible de prévoir un dispositif inverseur de sens à tout autre endroit des chaînes cinématiques, y compris dans l'inverseur 11 lui-même. On peut également concevoir d'autres types de différentiel, par exemple un différentiel à double satellite planétaires ne nécessitant plus l'interposition d'un inverseur de sens dans la chaîne correctrice.As can be seen, the
Dans l'exemple représenté à la
Dans la description précédente on a décrit la correction d'assiette de la plate-forme 3 selon une seule direction. En revenant à la
La cage 10 et les éléments qu'elle contient, agissent comme un deuxième contrepoids pour maintenir la plate-forme 3 en position horizontale lorsque la montre est inclinée par le mouvement du poignet dans un plan perpendiculaire à l'axe A2. Etant donné que la masse la plus importante de ce deuxième contrepoids est le contrepoids 9 lui-même, l'axe A2 sera de préférence non secant avec l'axe A1 pour augmenter le moment entraînant la rotation de la cage 10.The cage 10 and the elements it contains, act as a second counterweight to maintain the
On retrouve comme précédemment une chaîne cinématique motrice à partir de la roue de barillet 7 et une chaîne cinématique correctrice à partir d'une roue 20 solidaire de la plaque supérieure 10c de la cage 10, ladite roue 20 pouvant venir de matière avec ladite plaque 10c, ces deux chaînes cinématiques étant reliées par un deuxième différentiel 21.As before, there is a driving kinematic chain from the barrel wheel 7 and a corrective kinematic chain from a
Le différentiel 21 est composé de mobiles 25a, 27, 29a et 29b analogues à ceux déjà décrits pour le premier différentiel 11 et il ne sera donc pas décrit plus avant. Il comporte une sortie de force motrice du barillet 7a constitué par un rouage conique 13 qui engrène avec la denture conique 15a du porte-satellite 15 du premier différentiel 11 pour transmettre le couple moteur à la roue entraîneuse 6. De même le deuxième différentiel 21 comporte une entrée reliée à la roue 20 de la cage 10 par un train de rouages 22, 24, 26, 28 conçu avec les mêmes contraintes que précédemment et qui ne sera donc pas décrit plus avant.The differential 21 is composed of
Ainsi on voit que le mécanisme qui vient d'être décrit permet de maintenir la plate-forme 3 horizontale quelles que soient les inclinaisons imposées à la montre dans des plans perpendiculaires aux axes A1 ou A2, et évidemment selon n'importe quelle autre inclinaison intermédiaire, de sorte que le dispositif réglant balancier-spiral ne subit plus d'influence de l'orientation spatiale de la montre.Thus, it can be seen that the mechanism which has just been described makes it possible to keep the
Pour une meilleure compréhension de l'invention on a volontairement, en quelque sorte, dédoublé des mobiles qui pourraient en fait parfaitement être fusionnés, par exemple pour réduire l'encombrement du dispositif. A titre d'exemple non limitatif, la roue d'échappement 5 et la roue entraîneuse 6 pourraient former un seul mobile.For a better understanding of the invention, it has voluntarily, in a way, duplicated mobiles that could in fact be perfectly merged, for example to reduce the size of the device. By way of non-limiting example, the
Selon un autre aspect de l'invention, le mouvement de la cage 10 est assimilable à celui d'une masse oscillante et il est possible de prévoir que la denture de la roue 20 de la cage 10 engrène avec un bloc de remontage automatique 40, ce qui permet en quelque sorte de "récupérer" l'énergie selon l'axe A2.According to another aspect of the invention, the movement of the cage 10 is comparable to that of an oscillating mass and it is possible to provide that the toothing of the
Selon une variante représentée à la
Cette variante, dans une forme simplifiée pourrait même avoir uniquement la fonction de remontage automatique bi-axes.This variant, in a simplified form could even have only the function of automatic winding bi-axis.
On observera enfin que les mobiles et les différentiels du mécanisme qui viennent d'être décrits permettent en outre très facilement, par les rapports d'engrenages, d'ajuster très facilement le couple et la vitesse de rotation de la roue d'échappement 5, ou de tout autre organe du dispositif réglant.Finally, it will be observed that the mobiles and the differentials of the mechanism which have just been described furthermore make it very easy, by the gear ratios, to very easily adjust the torque and the rotational speed of the
