Arrière-plan de l'inventionBackground of the invention

Il est souvent utile, dans un mécanisme d'horlogerie, de pouvoir commander un même mobile pivotant de façon à obtenir une réponse différente selon le sens de pivotement appliqué. Une telle fonction est en général exercée par un mécanisme à différentiel, encombrant et coûteux, surtout si ce mobile comporte plusieurs entrées.It is often useful, in a clockwork mechanism, to be able to control the same pivoting mobile so as to obtain a different response depending on the direction of pivoting applied. Such a function is generally exercised by a differential mechanism, bulky and expensive, especially if the mobile has several inputs.

Un canon est disposé dans le logement de couronne et comporte des moyens de fixation d'une tige de remontoir. Le premier élément déformable est solidaire de ce canon quelle que soit la valeur du couple de rotation, et l'élément rigide est fixe par rapport à la couronne. Le premier élément déformable coopère en rotation avec la périphérie interne de l'élément rigide qui est de forme annulaire.The MECO patent EP1738229B1 discloses a hollow ring having a first resiliently deformable element cooperating in a first direction of rotation with a rigid element, as long as the rotational torque transmitted by one of these elements to the other is less than a pre-defined value, beyond which this first deformable element is likely to deform to disengage its cooperation with this rigid element. A barrel is disposed in the crown housing and comprises means for fixing a winding stem. The first deformable element is integral with this gun regardless of the value of the couple rotation, and the rigid element is fixed relative to the crown. The first deformable element cooperates in rotation with the inner periphery of the rigid element which is of annular shape.

Ce moyen de rappel élastique comporte des cliquets élastiques qui ne sont pas continuellement en contact avec cette seconde pièce d'entraînement.The document CH 702 924 B1 PATEK PHILIPPE takes this principle, and describes a pinion and a wheel coaxially mounted, with a single elastic return means which cooperates, in certain discontinuous positions, only between a drive part integral with the pinion, and other share a female wolf tooth teeth that includes another second integral drive part of the wheel. This elastic return means comprises resilient pawls which are not continuously in contact with this second drive part.

L'invention concerne un mobile d'horlogerie à roue unidirectionnelle 8 comportant un arbre 80 porteur d'un pignon 81 et d'au moins une première roue 82 coaxiale avec ce pignon 81 et montée pivotante sur cet arbre 80.The invention relates to a unidirectional wheel watchmaker 8 having a shaft 80 carrying a pinion 81 and at least a first wheel 82 coaxial with the pinion 81 and pivotally mounted on the shaft 80.

Cette première roue 82 est liée à l'arbre 80 par des premiers moyens de rappel élastique en rotation ou au moins un premier ressort 84 constituant des premiers moyens de débrayage 91, et qui exercent sur cette première roue 82 un effort de friction.This first wheel 82 is connected to the shaft 80 by first elastically rotating return means or at least a first spring 84 constituting first disengaging means 91, and which exert on this first wheel 82 a frictional force.

Avantageusement ces premiers moyens de débrayage 91 exercent sur cette première roue 82 un effort de friction dont le moment du couple est différent selon le sens de pivotement relatif entre les premiers moyens de débrayage 91 et la première roue 82.Advantageously, these first disengaging means 91 exert on this first wheel 82 a friction force whose moment of the torque is different according to the direction of relative pivoting between the first disengaging means 91 and the first wheel 82.

Selon l'invention, et tel que visible en figure 1, le mobile 8 comporte encore une deuxième roue 86 montée pivotante sur l'arbre 80, et qui est liée à cet arbre 80 par des deuxièmes moyens de rappel élastique en rotation ou au moins un deuxième ressort 88 constituant des deuxièmes moyens de débrayage 92, et qui exercent sur cette deuxième roue 86 un effort de friction.According to the invention, and as visible in figure 1 , the mobile 8 further comprises a second wheel 86 pivotally mounted on the shaft 80, and which is linked to this shaft 80 by second elastic return means of rotation or at least one second spring 88 constituting second disengaging means 92, and which exert on this second wheel 86 a frictional force.

Avantageusement les deuxièmes moyens de débrayage 92 exercent sur cette deuxième roue 86 un effort de friction dont le moment du couple est différent selon le sens de pivotement relatif entre les deuxièmes moyens de débrayage 92 et la deuxième roue 86.Advantageously, the second disengaging means 92 exert on this second wheel 86 a friction force whose moment of torque is different in the direction of relative pivoting between the second disengaging means 92 and the second wheel 86.

Dans une réalisation particulière, le premier ressort 84 est agencé pour générer un sens unidirectionnel de pivotement sans jeu de la première roue 82 par rapport à l'arbre 80 du mobile 8, de façon à prévenir toute transmission d'un couple à un mobile antagoniste par une première denture 85 que comporte la première roue 82 lors de l'application d'un couple au pignon 81.In a particular embodiment, the first spring 84 is arranged to generate a unidirectional direction of pivoting without play of the first wheel 82 relative to the shaft 80 of the mobile 8, so as to prevent any transmission of a torque to an opposing mobile by a first toothing 85 that includes the first wheel 82 when applying a torque to the pinion 81.

Dans une réalisation particulière, le deuxième ressort 88 est agencé pour générer un sens unidirectionnel de pivotement sans jeu de la deuxième roue 86 par rapport à l'arbre 80 du mobile 8, de façon à prévenir toute transmission d'un couple à un mobile antagoniste par une deuxième denture 89 que comporte la deuxième roue 86 lors de l'application d'un couple au pignon 81.In a particular embodiment, the second spring 88 is arranged to generate a unidirectional pivoting direction without play of the second wheel 86 with respect to the shaft 80 of the moving part 8, so as to prevent any transmission of a torque to an opposing mobile by a second toothing 89 that includes the second wheel 86 when applying a torque to the pinion 81.

Dans une réalisation particulière, le deuxième ressort 88 est agencé pour générer un sens unidirectionnel de pivotement sans jeu de la deuxième roue 86 par rapport à l'arbre 80 du mobile 8, de façon à prévenir toute transmission d'un couple à un mobile antagoniste par le pignon 81 lors de l'application d'un couple à une deuxième denture 89 que comporte la deuxième roue 86.In a particular embodiment, the second spring 88 is arranged to generate a unidirectional pivoting direction without play of the second wheel 86 with respect to the shaft 80 of the moving part 8, so as to prevent any transmission of a torque to an opposing mobile by the pinion 81 when applying a torque to a second toothing 89 that includes the second wheel 86.

Dans une réalisation particulière, la première roue 82 et la deuxième roue 86 sont unidirectionnelles dans le même sens de pivotement.In a particular embodiment, the first wheel 82 and the second wheel 86 are unidirectional in the same direction of pivoting.

Dans une réalisation particulière, la première roue 82 comporte une première denture 85 qui est différente d'une deuxième denture 89 que comporte lad deuxième roue 86.In a particular embodiment, the first wheel 82 comprises a first toothing 85 which is different from a second toothing 89 which the second wheel 86 comprises.

Dans une réalisation particulière, le premier ressort 84 est identique au deuxième ressort 88.In a particular embodiment, the first spring 84 is identical to the second spring 88.

L'invention concerne encore un mouvement d'horlogerie 100 comportant au moins un tel mobile 8. Selon l'invention ce mouvement 100 comporte au moins un mobile émetteur 1, 2, engrenant avec une denture 85, 89, d'une roue 82,86, de ce mobile 8, et un mobile récepteur 3 engrenant avec le pignon 81 du mobile 8.The invention also relates to a watch movement 100 comprising at least one such mobile 8. According to the invention this movement 100 comprises at least one mobile transmitter 1, 2, meshing with a set of teeth 85, 89, of a wheel 82, 86, of this mobile 8, and a mobile receiver 3 meshing with the pinion 81 of the mobile 8.

Dans une réalisation particulière, le mouvement 100 comporte au moins un premier mobile émetteur 1 engrenant avec une première denture 85 d'une première roue 82 dudit mobile 8 et un deuxième mobile émetteur 2 engrenant avec une deuxième denture 89 d'une deuxième roue 86 du mobile 8.In a particular embodiment, the movement 100 comprises at least a first mobile transmitter 1 meshing with a first toothing 85 of a first wheel 82 of said mobile 8 and a second mobile transmitter 2 meshing with a second set of teeth 89 of a second wheel 86 of mobile 8.

L'invention concerne encore une pièce d'horlogerie 200, notamment une montre, comportant au moins un tel mouvement 100.The invention also relates to a timepiece 200, in particular a watch, comprising at least one such movement 100.

Ainsi, des moyens de débrayage 9, constitués par les premiers moyens de rappel élastique en rotation ou par le au moins un premier ressort 84, exercent sur la première roue 82 un effort de friction, dont le moment du couple est différent selon le sens de pivotement relatif entre ces moyens de débrayage 9, et la première roue 82.Thus, disengaging means 9, constituted by the first resiliently rotating return means or by the at least one first spring 84, exert on the first wheel 82 a friction force, the moment of the torque is different in the direction of relative pivoting between these disengaging means 9, and the first wheel 82.

La figure 1 montre une réalisation particulière, non limitative, d'un mobile 8 monté, composé de cinq pièces: un axe 80, de préférence décolleté en acier 20AP standard, la première roue 82 et la deuxième roue 86, qui pivotent librement, et le premier ressort 84 et le deuxième ressort 88 qui garantissent l'entraînement ou non-entraînement de ces roues.The figure 1 shows a particular, non-limiting embodiment of a mobile 8 mounted, consisting of five parts: an axis 80, preferably a 20AP steel standard neck, the first wheel 82 and the second wheel 86, which rotate freely, and the first spring 84 and the second spring 88 which guarantee the training or non-driving of these wheels.

En ce qui concerne la première roue 82 et la deuxième roue 86 unidirectionnelles, fabriquées de préférence en Cuivre-Béryllium durci (CuBe), leur fonction est d'entraîner l'axe 80 lorsqu'elles subissent un couple d'origine externe.As regards the unidirectional first wheel 82 and second wheel 86, preferably made of hardened copper-beryllium (CuBe), their function is to drive the axis 80 when they undergo a torque of external origin.

Par contre, elles ne doivent pas transmettre de couple lorsqu'elles sont entraînées par l'axe 80 (système de débrayage entre les deux roues). De plus, la roue 82 ou 86 ne doit pas avoir d'angle mort, au contraire d'une roue cliquet par exemple. De plus, les dentures 85 et 89 de ces roues 82 et 86 sont optimisées pour minimiser le jeu d'engrenage. Le comportement très différent de chaque ressort 84, 88, selon le sens du couple qui lui est appliqué peut être simplifié en un premier sens « libre » et un deuxième sens « friction » d'entraînement. Toutefois, même dans le sens dit libre du ressort, il existe un petit frottement entre le ressort et la roue concernée, du fait d'une légère précontrainte appliquée au ressort sur son diamètre extérieur, ce qui implique que la roue sera entraînée par ce faible couple de frottement, et tournera jusqu'à venir rattraper le jeu avec la roue ou le pignon suivant.However, they must not transmit torque when they are driven by the axis 80 (disengaging system between the two wheels). In addition, the wheel 82 or 86 must have no dead angle, unlike a ratchet wheel, for example. In addition, the teeth 85 and 89 of these wheels 82 and 86 are optimized to minimize gearing. The very different behavior of each spring 84, 88, according to the direction of the torque applied to it can be simplified in a first "free" direction and a second "friction" drive direction. However, even in the so-called free direction of the spring, there is a small friction between the spring and the wheel concerned, because of a slight preload applied to the spring on its outer diameter, which implies that the wheel will be driven by this weak friction torque, and will turn up to come catch the game with the next wheel or pinion.

Les deux roues 82 et 86 sont de préférence conçues pour recevoir le même ressort, ce qui limite le nombre de composants. De plus, leurs diamètres de pivotement sont de préférence identiques. Cela permet d'avoir la même dimension pour l'attache du ressort au centre sur l'entraînement, notamment six pans, de l'axe 80.The two wheels 82 and 86 are preferably designed to receive the same spring, which limits the number of components. In addition, their pivot diameters are preferably identical. This allows to have the same size for the attachment of the spring in the center on the drive, including hexagon, axis 80.

Le premier 84 ou deuxième 88 ressort flexible a pour fonction d'entraîner l'axe 80 lorsqu'il travaille en sens bloquant. Dans le cas où l'axe 80 entraîne un ressort, il ne devrait pas entraîner la roue correspondante. De préférence, on minimise le couple de frottement et on maximise le couple de blocage.The first 84 or second 88 flexible spring has the function of driving the axis 80 when working in blocking direction. In the case where the axis 80 drives a spring, it should not drive the corresponding wheel. Preferably, the friction torque is minimized and the locking torque is maximized.

On comprend qu'un tel système de débrayage est indispensable pour éviter un retour de force intempestif par un rouage. Le mobile 8 forme une roue unidirectionnelle dont le fonctionnement ressemble à une roue cliquet d'inversion. Le mobile 8 représente un gros progrès par rapport aux inverseurs connus, car il est beaucoup moins volumineux, et donc plus facile à implanter dans un mouvement 100. Le mobile 8 selon l'invention n'a pas d'angle mort, ce qui autorise son montage dans un mouvement automatique.It is understood that such a disengagement system is essential to prevent inadvertent force feedback by a cog. The mobile 8 forms a unidirectional wheel whose operation resembles a reversing ratchet wheel. The mobile 8 is a big improvement over the known inverters, because it is much less bulky, and therefore easier to implant in a movement 100. The mobile 8 according to the invention has no dead angle, which allows its assembly in an automatic movement.

Les figures 2 à 8 illustrent différentes géométries, non limitatives, de ressorts, qui sont applicables aussi bien au premier ressort 84 qu'au deuxième ressort 88. La figure 2 montre plus particulièrement le premier ressort 84 logé dans la première roue d'entraînement de rochet supplémentaire 82, et les figures 3 à 8 le deuxième ressort 88 logé dans la deuxième roue d'entraînement de rochet supplémentaire 86. Leur fixation à la roue correspondante est basée sur une friction: une spire externe 841, respectivement 881, du premier ressort 84, respectivement du deuxième ressort 88, coopère avec un logement 820, respectivement 860, de la roue 82, respectivement 86, dans laquelle elle est maintenue par friction au niveau de sa périphérie ou/et d'ergots 84A, respectivement 88A que comporte le premier ressort 84, respectivement deuxième ressort 88. La partie intérieure de chaque ressort, 842, respectivement 882, coopère avec l'arbre 80, par une partie femelle 840, respectivement 880, du premier ressort 84, respectivement du deuxième ressort 88, de profil complémentaire à une partie mâle 800 de l'arbre 80.The Figures 2 to 8 illustrate various non-limiting geometries of springs which are applicable to both the first spring 84 and the second spring 88. The figure 2 shows more particularly the first spring 84 housed in the first additional ratchet drive wheel 82, and the Figures 3 to 8 the second spring 88 housed in the second additional ratchet drive wheel 86. Their attachment to the corresponding wheel is based on a friction: an outer turn 841, respectively 881, of the first spring 84, respectively of the second spring 88, cooperates with a housing 820, respectively 860, of the wheel 82, respectively 86, in which it is held by friction at its periphery or / and lugs 84A, respectively 88A that includes the first spring 84, respectively second spring 88. The inner part of each spring, 842, respectively 882, cooperates with the shaft 80, by a female portion 840, respectively 880, of the first spring 84, respectively of the second spring 88, of complementary profile to a male portion 800 of the shaft 80.

Le profil particulier des ressorts illustrés, avec une raideur asymétrique d'au moins un bras 843, respectivement 883, joignant la partie intérieure de chaque ressort, 842, respectivement 882, à sa partie externe 841, respectivement 881, permet d'appliquer un couple avec un fort différentiel de moment, selon que le mouvement de pivotement relatif entre l'arbre 80 et la roue respective, se fait dans un sens ou dans l'autre. Le rapport du couple exercé dans un sens par rapport à l'autre est de préférence supérieur à 3 ; selon la forme du ressort, les sections utilisées, et les couples de matériaux en présence, ce rapport peut être notablement augmenté, en particulier au-delà d'un facteur 10.The particular profile of the illustrated springs, with an asymmetrical stiffness of at least one arm 843, respectively 883, joining the inner part of each spring, 842, respectively 882, to its outer portion 841, respectively 881, makes it possible to apply a torque with a strong moment differential, depending on whether the relative pivoting movement between the shaft 80 and the respective wheel, is in one direction or the other. The ratio of the torque exerted in one direction with respect to the other is preferably greater than 3; depending on the shape of the spring, the sections used, and the pairs of materials present, this ratio can be notably increased, in particular beyond a factor of 10.

Sur les figures 2 et 3, le profil du ressort est fermé : la partie intérieure de chaque ressort, 842, respectivement 882, a la forme d'un losange centré sur l'arbre 80, une des extrémités A du losange constitue le début de la partie externe 841, respectivement 881, laquelle est circulaire selon presque un tour complet, avant de s'enrouler sur elle-même au point C et d'y former un bras 843, respectivement 883, en secteur circulaire d'environ un demi-tour, de rayon inférieur à celui de la partie externe, s'accrochant au point B à l'autre extrémité du losange symétrique à la première extrémité A.On the Figures 2 and 3 , the profile of the spring is closed: the inner part of each spring, 842, respectively 882, has the shape of a rhombus centered on the shaft 80, one of the ends A of the rhombus constitutes the beginning of the outer portion 841, respectively 881, which is circular in almost a complete turn, before winding on itself at point C and forming an arm 843, respectively 883, in a circular sector of about a half-turn, radius less than that of the outer part, clinging to point B at the other end of the symmetrical rhombus at the first end A.

Sur la figure 5, le profil du ressort est ouvert : la partie intérieure, 842, respectivement 882, a la forme d'un disque prolongé sur un rayon par un triangle, dont la pointe distale H constitue le départ d'un bras 843, respectivement 883, en spirale croissante sur environ un demi-tour jusqu'au point I où démarre une partie externe 841, respectivement 881, circulaire, avant de s'arrêter à une extrémité distale J, après environ un tour et quart par rapport au point H.On the figure 5 , the profile of the spring is open: the inner part, 842, respectively 882, has the shape of a disk extended on a radius by a triangle, whose distal tip H constitutes the departure of an arm 843, respectively 883, in spiral increasing about half a turn to the point I where starts an outer portion 841, respectively 881, circular, before stopping at a distal end J, after about a turn and a quarter with respect to the point H.

Sur la figure 6, le profil du ressort est ouvert, le ressort comportant deux brins symétriques : la partie intérieure, 842, respectivement 882, a la forme d'un disque auquel s'accroche en K, N, un bras 843, respectivement 883, en spirale croissante sur environ trois quarts de tour jusqu'au point L, P, où démarre une partie externe 841, respectivement 881, circulaire d'un demi-tour, avant de s'arrêter à une extrémité distale M, Q.On the figure 6 , the profile of the spring is open, the spring having two symmetrical strands: the inner part, 842, respectively 882, has the shape of a disk which is hooked in K, N, an arm 843, respectively 883, spiraling increasing about three quarters of a turn to the point L, P, where starts a outer portion 841, respectively 881, circular one-half turn, before stopping at a distal end M, Q.

Sur la figure 7, le profil du ressort est fermé, et comporte un maillage avec un pas de 120°: la partie intérieure, 842, respectivement 882, a la forme d'un disque dont part au point R un bras 843, respectivement 883, sensiblement radial mais incurvé, lequel rejoint au point S une corde 885 qui joint deux secteurs circulaires de plus grand diamètre, dont un secteur TU formant une partie externe 841, respectivement 881, le ressort repartant au point U sur une autre corde 885 faisant environ 120° avec la précédente, et rejoignant au point V un autre arc incurvé radial similaire au premier, le point V étant le conjugué du point S de départ.On the figure 7 , the profile of the spring is closed, and comprises a mesh with a pitch of 120 °: the inner part, 842, respectively 882, has the shape of a disc whose part R at the point R an arm 843, respectively 883, substantially radial but curved, which joins at point S a rope 885 which joins two circular sectors of larger diameter, one sector TU forming an outer portion 841, respectively 881, the spring starting at point U on another rope 885 making about 120 ° with the previous, and joining at point V another radial arc similar to the first, the point V being the conjugate of the starting point S.
