Description

La présente invention concerne le domaine de l'horlogerie. L'invention porte en particulier sur un dispositif manuel de réglage et/ou de commande d'une fonction d'une pièce d'horlogerie comportant une boîte logeant un mouvement d'horlogerie, ledit dispositif manuel comprenant une tige et une couronne escamotable montée dans ladite boîte.The present invention relates to the field of watchmaking. The invention relates in particular to a manual device for adjusting and / or controlling a function of a timepiece comprising a box housing a clockwork movement, said manual device comprising a rod and a retractable crown mounted in a said box.

En horlogerie, la pièce qui sert en général au réglage des fonctionnalités principales d'une pièce d'horlogerie est appelée la couronne. Dans le cas d'une montre, la couronne est en règle générale fixée latéralement sur la carrure de la montre, la carrure étant la pièce au sein de laquelle est logé le système permettant l'affichage de l'heure sur le cadran.In watchmaking, the piece that is generally used to adjust the main features of a timepiece is called the crown. In the case of a watch, the crown is generally attached laterally to the middle part of the watch, the middle part being the part within which is housed the system for displaying the time on the dial.

Il existe par ailleurs deux grands types de systèmes permettant de mesurer le temps qui sont utilisés en horlogerie pour être implantés au sein de pièces d'horlogerie, notamment de boîtes de montres. D'une part, les systèmes électroniques, dits à quartz, sont généralement alimentés par une pile et comportent un oscillateur à quartz et des composants électroniques implantés sur un circuit électronique qui permet de mesurer et afficher le temps avec précision. D'autre part, les systèmes mécaniques sont généralement autonomes en énergie, ne nécessitent pas d'être alimentés par une pile et comportent généralement un ressort, dit spiral, et un certain nombre de pièces mécaniques, notamment des engrenages, montées au sein d'un système mécanique qu'on appelle le mouvement. La couronne permet, en règle générale, d'effectuer le réglage, d'activer ou de désactiver les fonctionnalités du mouvement d'une pièce d'horlogerie, généralement au moyen d'une tige qui la lie cinématiquement au mouvement de la pièce d'horlogerie.There are also two major types of time measurement systems that are used in watchmaking to be implanted within timepieces, including watch cases. On the one hand, the so-called quartz electronic systems are generally powered by a battery and comprise a quartz oscillator and electronic components implanted on an electronic circuit which allows accurate measurement and display of time. On the other hand, the mechanical systems are generally energy independent, do not need to be powered by a battery and generally comprise a spring, said spiral, and a number of mechanical parts, including gears, mounted within a system mechanical called movement. The crown makes it possible, as a general rule, to adjust, to activate or deactivate the functionalities of the movement of a timepiece, generally by means of a rod which kinematically links it to the movement of the workpiece. watchmaking.

L'invention s'applique en particulier aux montres mécaniques qui comportent une couronne de réglage et/ou de commande du mouvement. Dans le cas d'une montre mécanique, on appelle la boîte l'ensemble constitué par le fond, la carrure et la partie qui fait la jonction entre la boîte et le verre de la montre qu'on appelle la lunette.The invention applies in particular to mechanical watches which comprise a setting ring and / or movement control. In the case of a mechanical watch, the box is called the set consisting of the bottom, the middle and the part that is the junction between the box and the watch glass called the bezel.

Or, sur la plupart des modèles de montres mécaniques et même sur certains modèles de montres à quartz, la couronne est généralement montée latéralement sur la carrure de la montre. De plus, la majorité des modèles de montres mécaniques vendues sur le marché comportent une couronne de réglage et/ou de commande dont la position est identique quelque soit le modèle de montre et se situe généralement en face de la position qui marque trois heures sur le cadran de la montre. De plus, dans la plupart des modèles de montres, la couronne est généralement complètement saillante sur la carrure de la montre, ceci permettant à un utilisateur de manipuler la couronne.However, on most models of mechanical watches and even some models of quartz watches, the crown is generally mounted laterally on the middle part of the watch. In addition, the majority of the mechanical watch models sold on the market comprise an adjusting crown and / or control whose position is identical regardless of the watch model and is generally in front of the position that marks three hours on the watch face. In addition, in most watch models, the crown is generally completely protruding on the middle of the watch, this allowing a user to manipulate the crown.

Cependant, le fait que la couronne soit implantée latéralement sur la carrure de la montre et soit saillante ne va pas sans poser divers problèmes.However, the fact that the crown is implanted laterally on the middle part of the watch and is protruding does not go without causing various problems.

En effet, dans le cas d'une montre-bracelet, le fait que la couronne soit saillante et fixée à fleur de la carrure crée un point faible en cas de choc de la montre contre une surface dure. Lors de chocs, qui peuvent être engendrés par toute sorte d'accidents, il peut en effet arriver que la couronne vienne à se tordre et même parfois à rompre. Ceci vient du fait que cette dernière est généralement liée au mouvement de la montre uniquement au moyen d'une tige très fine. Ainsi, lors de chocs latéraux sur la couronne, cette dernière peut effectivement se tordre. Lorsque la tige est tordue, il va sans dire que la couronne ne permet plus de régler ou d'effectuer quelque commande que ce soit sur le mouvement de la montre.Indeed, in the case of a wristwatch, the fact that the crown is protruding and fixed flush with the middle part creates a weak point in case of shock of the watch against a hard surface. In shocks, which can be caused by any kind of accidents, it may happen that the crown comes to twist and even to break. This is because the latter is generally related to the movement of the watch only by means of a very thin rod. Thus, during lateral shocks on the crown, the latter can actually twist. When the rod is twisted, it goes without saying that the crown no longer allows to adjust or perform any command whatsoever on the movement of the watch.

Un autre problème qui se pose provient du fait que, lors de mauvaises manipulations, une couronne saillante peut venir s'accrocher à toutes sortes d'objets, notamment aux vêtements, gourmettes ou tout autre type de bijou qui peut être porté au poignet. Ceci peut provoquer une gêne pour l'utilisateur. De plus, en règle générale et afin de permettre une prise suffisante, les couronnes comportent généralement des stries qui constituent des arrêtes vives qui peuvent user les vêtements en contact avec elles.Another problem arises from the fact that, during mishandling, a protruding crown can cling to all kinds of objects, including clothing, curbs or any other type of jewelry that can be worn on the wrist. This can cause discomfort for the user. In addition, as a general rule and in order to allow sufficient grip, the crowns generally include ridges that constitute sharp edges that can wear clothes in contact with them.

Ensuite, un autre problème qui peut se poser vient de la gêne occasionnée par la présence de la couronne elle même. En effet, lorsque la couronne est saillante, cette dernière forme une sorte d'ergot qui peut en effet, lors de certains mouvements du poignet, venir frotter contre la peau de l'utilisateur. Ceci peut également provoquer une certaine gêne pour l'utilisateur.Then another problem that may arise comes from the inconvenience caused by the presence of the crown itself. Indeed, when the crown is protruding, the latter forms a kind of pin that can indeed, during some wrist movements, come rub against the skin of the user. This can also cause some inconvenience for the user.

Finalement, un autre problème qui se pose est lié à l'esthétique de la pièce d'horlogerie, notamment de la montre. En effet, une couronne saillante crée une sorte de protubérance au sein de la structure circulaire de la boîte de la montre. Cette protubérance, par le fait qu'elle vient rompre la continuité de la structure circulaire de la montre, nuit considérablement à l'esthétique de celle-ci.Finally, another problem that arises is related to the aesthetics of the timepiece, including the watch. Indeed, a protruding crown creates a kind of protuberance within the circular structure of the watch case. This protuberance, by the fact that it breaks the continuity of the circular structure of the watch, significantly affects the aesthetics of the latter.

Diverses solutions de l'état de la technique renseignent sur différents systèmes visant à renforcer le montage de la couronne sur la boîte.Various solutions of the state of the art provide information on various systems to strengthen the mounting of the crown on the box.

Une première solution consiste à usiner sur le boitier un pas de vis sur lequel la couronne vient se visser. Cette solution a l'avantage de fixer plus solidement la couronne sur le boîtier mais, à cause du fait que la couronne est toujours saillante et montée plus ou moins à fleur du boitier, ne garantit pas qu'en cas de choc celle-ci puisse se tordre ou rompre. De plus, lorsque l'utilisateur veut effectuer le réglage du mouvement, il doit d'abord dévisser la couronne et c'est seulement une fois cette dernière complètement dévissée que l'utilisateur peut ensuite amener la couronne dans un position permettant le réglage ou la commande du mouvement. Cette solution nuit à la facilité d'utilisation de la couronne. Un tel mécanisme de blocage est par exemple décrit dans le document FR 2783939 .A first solution is to machine on the housing a screw thread on which the crown is screwed. This solution has the advantage of fixing more securely the crown on the housing but, because of the fact that the crown is always protruding and mounted more or less flush with the housing, does not guarantee that in case of shock it can to twist or break. In addition, when the user wants to perform the adjustment of the movement, it must first unscrew the crown and only once the latter completely unscrewed that the user can then bring the crown in a position allowing adjustment or movement control. This solution affects the ease of use of the crown. Such a locking mechanism is for example described in the document FR 2783939 .

Une deuxième solution consiste à mettre en place un dispositif qui permet à la couronne de se rétracter complètement au sein du boîtier. Un tel dispositif est décrit dans la demande de brevet français FR2030095 . Le mécanisme comporte des bras d'arrêt élastiques 11 qui, sous l'effet d'une pression, s'écartent et viennent se bloquer contre une bague 9. Le mécanisme présente toutefois certains défauts. D'une part, lors d'une utilisation prolongée, on peut imaginer que les bras élastiques perdent de leur élasticité, ce qui aurait pour conséquence que la couronne ne serait plus efficacement bloquée. D'autre part, la bague servant de blocage peut s'user, suite à une utilisation prolongée, ce qui aurait également pour conséquence de ne plus assurer efficacement le blocage de celle-ci.A second solution is to set up a device that allows the crown to retract completely within the housing. Such a device is described in the French patent application FR2030095 . The mechanism comprises elastic stop arms 11 which, under the effect of pressure, deviate and come to lock against a ring 9. However, the mechanism has certain defects. On the one hand, during prolonged use, it is conceivable that the elastic arms lose their elasticity, which would have the consequence that the crown would no longer be effectively blocked. On the other hand, the locking ring can wear out, following prolonged use, which also has the effect of not effectively ensure blocking thereof.

La figure 1 représente une vue en coupe d'un premier mode d'exécution du dispositif de réglage et/ou de commande selon l'invention. Le dispositif 1 comprend une tige 3 et une couronne escamotable 4 et est fixé dans un logement creusé perpendiculairement dans une boîte de montre 2. La couronne escamotable 4 comprend un corps cylindrique présentant une creusure cylindrique 5 borgne entourant un passage tubulaire 6 destiné à entourer ladite tige 3 et à la lier cinématiquement en rotation avec la couronne escamotable 4. La tige 3, de section carrée ou polygonale, est logée à une extrémité dans le passage tubulaire 6 alors que l'autre extrémité de la tige 3 est logée dans un pont de sélection de fonction du mouvement 7 qui permet de transmettre les rotations de la tige au mouvement de la montre. La section du passage tubulaire 6 peut, de préférence, être carrée ou polygonale. Dans le cas présent la partie inférieure du passage est munie d'une vis 61 doté d'un passage de section carré ou polygonale conjuguée à la section de la tige 3 assurant la liaison cinématique en rotation de la tige 3 et de la couronne 4. Au sein de la creusure cylindrique 5 est logé un premier ressort 8 permettant de pousser la couronne 4 vers l'extérieur afin de faire passer celle-ci d'une position de repos, dans laquelle la couronne est complètement escamotée au sein de la boîte de la montre et aucune commande ni aucun réglage du mouvement ne sont possibles, à une position de travail dans laquelle la couronne est saillante à la surface de la montre et il est possible de commander ou de régler le mouvement de la montre. Le processus permettant le passage de la position de repos à la position de travail sera décrit plus en détail dans la suite de la description. La couronne comporte de plus un plongeur 9 ayant une extrémité conique qui, lorsque la couronne 4 se trouve en position de repos, vient se loger dans un trou 25 prévu à cet effet dans le pont se sélection de fonction du mouvement 7. Sur la figure 1, le dispositif de réglage et/ou de commande selon l'invention est représenté en position de repos et le plongeur 9 est logé dans le trou 25 prévu à cet effet dans le pont de sélection de fonction du mouvement 7, ce qui neutralise tout réglage et toute commande du mouvement. Ceci est décrit plus en détail en référence aux figures 3 à 5.The figure 1 represents a sectional view of a first embodiment of the adjustment device and / or control device according to the invention. The device 1 comprises a rod 3 and a retractable crown 4 and is fixed in a housing hollowed perpendicularly in a watch case 2. The retractable crown 4 comprises a cylindrical body having a blind cylindrical recess 5 surrounding a tubular passage 6 intended to surround said 3 and rod kinematically in rotation with the retractable crown 4. The rod 3, of square or polygonal section, is housed at one end in the tubular passage 6 while the other end of the rod 3 is housed in a bridge movement function selection 7 which allows to transmit the rotations of the rod to the movement of the watch. The section of the tubular passage 6 may preferably be square or polygonal. In this case the lower part of the passage is provided with a screw 61 having a passage of square or polygonal section conjugate to the section of the rod 3 ensuring the kinematic connection in rotation of the rod 3 and the crown 4. Within the cylindrical hollow 5 is housed a first spring 8 for pushing the crown 4 outwards in order to move it to a rest position, in which the crown is completely retracted within the box. the watch and no control or adjustment of the movement are possible at a working position in which the crown is projecting on the surface of the watch and it is possible to control or adjust the movement of the watch. The process allowing the transition from the rest position to the working position will be described in more detail later in the description. The ring further comprises a plunger 9 having a conical end which, when the ring 4 is in the rest position, is housed in a hole 25 provided for this purpose in the bridge is selected function of the movement 7. On the figure 1 , the adjustment and / or control device according to the invention is shown in the rest position and the plunger 9 is housed in the hole 25 provided for this purpose in the function selection bridge of the movement 7, which neutralizes any adjustment and any control of the movement. This is described in more detail with reference to Figures 3 to 5 .

Le dispositif de réglage et/ou de commande comprend par ailleurs une base 10 en forme couvercle cylindrique fixée dans la boîte 2 au moyen de deux vis (non représentées), un tube fraisé 11, de préférence soudé au laser dans la base 10, une bague crantée 12, de préférence soudée au laser dans le tube fraisé 11, un tube cranté 13, de préférence également soudé au laser dans le tube fraisé 11, une bague d'arrêt 14, de préférence soudée au laser à l'extrémité supérieure du tube cranté 13, et une bague d'indexation 15 apte à pivoter et à coulisser à l'intérieur du tube cranté 13 lorsque la couronne escamotable passe de la position de repos à la position de travail.The adjustment and / or control device further comprises a base 10 in the form of a cylindrical cover fixed in the box 2 by means of two screws (not shown), a milled tube 11, preferably laser-welded in the base 10, a toothed ring 12, preferably laser-welded in the milled tube 11, a notched tube 13, preferably also laser-welded in the milled tube 11, a bushing 14, preferably laser-welded at the upper end of the notched tube 13, and an indexing ring 15 adapted to pivot and slide inside the notched tube 13 when the retractable crown passes from the position of rest at the working position.

Sur la figure 1, la couronne est représentée sous une forme simplifiée. La figure 2 représente pour plus de clarté une vue éclatée de la couronne escamotable. La couronne escamotable 4 comprend un corps cylindrique 16 à l'intérieur duquel la creusure cylindrique borgne 5 permet de loger le ressort 8, un joint d'étanchéité annulaire 17 logé dans une saignée annulaire latérale 161, une bague 18, une coiffe 19 et un cabochon céramique 20. Par ailleurs, le plongeur 9 est positionné sur une paire de ressorts 91 qui permettent le mouvement du plongeur 9 lorsque la couronne passe de la position de repos à la position de travail. Le tube cranté 13 comporte en son intérieur des rainures 21 et des nervures 22 creusées de façon à ce que la bague d'indexation 15 puisse coulisser à l'intérieur du tube cranté 13. La couronne escamotable comprend finalement une vis 61 dont l'intérieur est creux et usiné de manière conjugué à la section de la tige 3 pour pouvoir être traversé par la tige 3. La vis 61 est vissée à l'extrémité inférieure du passage tubulaire 6 et permet de solidariser en translation la bague d'indexation 15 avec la couronne escamotable 4 lorsque celle-ci passe de la position de repos à la position de travail et de lier cinématiquement en rotation la couronne 4 et la tige 3.On the figure 1 , the crown is represented in a simplified form. The figure 2 represents for clarity an exploded view of the retractable crown. The retractable crown 4 comprises a cylindrical body 16 inside which the blind cylindrical hollow 5 accommodates the spring 8, an annular seal 17 housed in a lateral annular groove 161, a ring 18, a cap 19 and a Ceramic cabochon 20. Furthermore, the plunger 9 is positioned on a pair of springs 91 which allow the plunger 9 to move when the crown moves from the rest position to the working position. The grooved tube 13 has in its grooves 21 and ribs 22 hollowed so that the indexing ring 15 can slide inside the notched tube 13. The retractable crown finally comprises a screw 61 whose inside is hollow and machined in a manner conjugated to the section of the rod 3 in order to be traversed by the rod 3. The screw 61 is screwed to the lower end of the tubular passage 6 and allows to fix in translation the indexing ring 15 with the retractable crown 4 when it moves from the rest position to the working position and cinematically connect the ring 4 and the rod 3 in rotation.

Le fonctionnement de la couronne escamotable va maintenant être décrit en détail en référence aux figures 3 à 5.The operation of the retractable crown will now be described in detail with reference to Figures 3 to 5 .

La figure 3 représente une vue en coupe de la couronne escamotable 4 lorsque celle-ci se trouve en position de repos. En position de repos, la couronne est presque entièrement escamotée au sein de la boîte 2. Seule la partie supérieure de la couronne, composée par le cabochon 20 et la partie supérieure de la coiffe 19, s'étend au-delà de la surface supérieure de la lunette de la boîte 2. La partie inférieure de la couronne est, en revanche, complètement escamotée au sein de la boîte 2. Dans cette position de repos, les dents de la bague d'indexation 15 sont bloquées contre les nervures 22 du tube cranté 13. En position de repos, les dents de la bague d'indexation 15 se trouvent donc en face des nervures 22 du tube cranté 13 ce qui interdit à la bague d'indexation 15 de remonter à l'intérieur du tube cranté 13. Comme on le voit également, dans la position de repos, le plongeur 9 s'étend au-delà de la partie inférieure de la couronne escamotable pour venir se loger à l'intérieur d'un trou 25 présent à cet effet sur le pont de sélection de fonction du mouvement 7, neutralisant tout réglage et toute commande du mouvement de la montre. La neutralisation du pont de fonction du mouvement 7 par le plongeur 9 sera décrite plus en détail en rapport avec les figures 10A à 10D.The figure 3 is a sectional view of the retractable crown 4 when it is in the rest position. In the rest position, the crown is almost entirely retracted within the box 2. Only the upper part of the crown, composed of the cabochon 20 and the upper part of the cap 19, extends beyond the upper surface. the lower part of the crown is, on the other hand, completely retracted within the box 2. In this rest position, the teeth of the indexing ring 15 are locked against the ribs 22 of the ring. Notched tube 13. In the rest position, the teeth of the indexing ring 15 are therefore in front of the ribs 22 of the notched tube 13, which prevents the indexing ring 15 from going up inside the notched tube 13 As is also seen, in the rest position, the plunger 9 extends beyond the lower part of the retractable crown to be housed inside a hole 25 provided for this purpose on the bridge. of function selection of motion 7, neutralized any adjustment and control of the movement of the watch. The neutralization of the bridge of movement 7 by the plunger 9 will be described in more detail in connection with the Figures 10A to 10D .

La figure 4 représente une vue selon une coupe axiale de la couronne escamotable 4 lorsque celle-ci se trouve en position basse. Sous l'effet d'une pression effectuée sur la couronne par l'utilisateur lorsque celle-ci se trouve en position de repos, les ressorts 8 et 91 se compriment et la couronne 4 passe tout d'abord par la position basse dans laquelle elle est complètement escamotée au sein de la boîte 2. Les ressorts sont comprimés et le plongeur 9 s'enfonce au maximum dans le trou 25 prévu à cet effet dans le pont de sélection de fonction du mouvement 7. En position basse, les dents de la bague d'indexation 15 viennent s'indexer avec les dents de la bague crantée 12, ce qui provoque une rotation de la bague d'indexation 15. Ce processus de passage entre la position de repos et la position de travail sera décrit plus en détail en référence aux figures 6 à 8.The figure 4 represents a view in axial section of the retractable crown 4 when it is in the low position. Under the effect of pressure applied to the crown by the user when the latter is in the rest position, the springs 8 and 91 are compressed and the ring 4 passes firstly by the low position in which it is completely retracted within the box 2. The springs are compressed and the plunger 9 sinks to the maximum in the hole 25 provided for this purpose in the function selection bridge of the movement 7. In the low position, the teeth of the indexing ring 15 come to index with the teeth of the toothed ring 12, which causes a rotation of the indexing ring 15. This process of passage between the rest position and the working position will be described in more detail with reference to Figures 6 to 8 .

La figure 5 représente une vue selon une coupe axiale de la couronne escamotable 4 lorsque celle-ci se trouve en position de travail. Dans cette position, les ressorts 8 et 91 sont détendus et la couronne est saillante sur la boîte. Par ailleurs, la bague d'indexation 15 a coulissé dans les rainures 21 du tube cranté 13 et est venue se bloquer contre la bague d'arrêt 14. De plus, sous l'effet des ressorts 91, le plongeur 9 remonte en laissant libre le pont de sélection de fonction du mouvement 7 ce qui permet d'effectuer des réglages ou des commandes sur le mouvement de la montre.The figure 5 represents a view in axial section of the retractable crown 4 when it is in the working position. In this position, the springs 8 and 91 are relaxed and the crown is protruding on the box. Furthermore, the indexing ring 15 has slid into the grooves 21 of the notched tube 13 and has come to lock against the stop ring 14. In addition, under the effect of the springs 91, the plunger 9 rises leaving free the function selection bridge of the movement 7 which allows to make adjustments or controls on the movement of the watch.

Le processus de passage de la position de repos dans laquelle la couronne 4 est escamotée au sein de la boîte 2 à la position de travail dans laquelle la couronne 4 est saillante sur la lunette de la boîte va maintenant être décrit plus en détail en référence aux figures 6 à 8.The process of passage from the rest position in which the crown 4 is retracted within the box 2 to the working position in which the crown 4 is projecting on the bezel of the box will now be described in more detail with reference to the Figures 6 to 8 .

La figure 6 représente la couronne escamotable 4 lorsque cette dernière se trouve en position de repos. Les dents de la bague d'indexation 15 se trouvent en face des nervures 22 du tube cranté 13 interdisant la remontée de la bague d'indexation 15 à l'intérieur de celui-ci. En position de repos, le plongeur 9 s'étend au-delà de la partie inférieure de la base 10 et vient bloquer le pont de sélection de fonction du mouvement 7 en venant se loger à l'intérieur d'un trou 25 prévu à cet effet dans le pont de sélection de fonction du mouvement 7. En position de repos, tout réglage ou commande du mouvement est impossible.The figure 6 represents the retractable crown 4 when the latter is in the rest position. The teeth of the indexing ring 15 are opposite the ribs 22 of the notched tube 13 preventing the raising of the indexing ring 15 inside thereof. In the rest position, the plunger 9 extends beyond the lower part of the base 10 and blocks the function selection bridge of the movement 7 coming to be housed inside a hole 25 provided for this purpose. effect in the motion function selection bridge 7. In the rest position, any adjustment or control of movement is impossible.

La figure 7 représente la couronne escamotable 4 en position basse à la suite d'une pression effectuée par l'utilisateur sur la couronne qui était au préalable soit en position de repos soit en position de travail. En position basse, le plongeur 9 s'étend au maximum au-delà de la base 10 ce qui contribue à remettre dans une position neutre le pont de sélection de fonction du mouvement 7.The figure 7 represents the retractable crown 4 in the low position following a pressure made by the user on the crown which was previously either in the rest position or in the working position. In the low position, the plunger 9 extends as far as possible beyond the base 10, which contributes to putting the function selection bridge of the movement 7 back into a neutral position.

De la position de repos, à la suite d'une pression effectuée sur la couronne 4 par l'utilisateur, les dents de la bague d'indexation 15 viennent s'indexer avec celles de la bague crantée 12. Grâce à la forme triangulaire des dents de la bague d'indexation 15 et des dents de la bague crantée 12 et grâce au déphasage existant entre les dents de la bague d'indexation 15 et celles de la bague crantée 12, lorsque les dents de la bague d'indexation 15 viennent s'indexer avec celles de la bague crantée 12, ceci provoque une première rotation de la bague d'indexation 15. Par conséquent, les dents de la bague d'indexation 15, qui étaient, lorsque la couronne se trouvait en position de repos, face aux nervures 22 du tube cranté 13, ces dents, suite à cette première rotation, ne sont plus exactement en face des nervures 22. Ensuite, lorsque l'utilisateur relâche la pression sur la couronne, les ressorts 8,91 (non représentés) contribuent à rappeler la couronne 4 vers le haut. Les dents de la bague d'indexation 15 viennent alors s'indexer avec les dents du tube cranté 13 ce qui provoque une deuxième rotation de la bague d'indexation et contribue ainsi à mettre les dents de la bague d'indexation 15 en face des rainures 21 du tube cranté 13. La bague d'indexation 15 peut alors coulisser à l'intérieur du tube cranté 13 pour rejoindre l'extrémité supérieure du tube crantée 13 et venir se bloquer contre la bague d'arrêt 14. La couronne est alors dans la position de travail.From the rest position, following a pressure carried on the crown 4 by the user, the teeth of the indexing ring 15 are indexed with those of the toothed ring 12. Due to the triangular shape of the teeth of the indexing ring 15 and the teeth of the toothed ring 12 and thanks to the phase difference existing between the teeth of the indexing ring 15 and those of the toothed ring 12, when the teeth of the indexing ring 15 come to index with those of the toothed ring 12, this causes a first rotation of the indexing ring 15. By Therefore, the teeth of the indexing ring 15, which were, when the crown was in the rest position, facing the ribs 22 of the notched tube 13, these teeth, following this first rotation, are no longer exactly opposite the ribs 22. Then, when the user releases the pressure on the crown, the springs 8,91 (not shown) contribute to recall the crown 4 upwards. The teeth of the indexing ring 15 then come to index with the teeth of the notched tube 13 which causes a second rotation of the indexing ring and thus contributes to putting the teeth of the indexing ring 15 opposite the grooves 21 of the notched tube 13. The indexing ring 15 can then slide inside the notched tube 13 to join the upper end of the toothed tube 13 and come to lock against the stop ring 14. The crown is then in the working position.

La figure 8 représente la couronne escamotable 4 lorsque cette dernière se trouve en position de travail. Dans cette position, les dents de la bague d'indexation 15 ont coulissé à l'intérieur des rainures 21 du tube cranté 13 et la bague d'indexation 15 est maintenant bloquée contre la bague d'arrêt 14. Le plongeur 9 est complètement remonté et laisse totalement libre le pont de sélection de fonction du mouvement 7 et la couronne 4 est bloquée en position de travail. Cette position permet de régler ou d'effectuer les commandes sur le mouvement de la montre d'une part en activant un des poussoirs 29 (représentés à la figure 11) et d'autre part en tournant la couronne dans un sens ou dans l'autre selon le processus de réglage propre au mouvement de la montre qui sera décrit par la suite.The figure 8 represents the retractable crown 4 when the latter is in the working position. In this position, the teeth of the indexing ring 15 have slid inside the grooves 21 of the notched tube 13 and the indexing ring 15 is now locked against the stop ring 14. The plunger 9 is completely reassembled and leaves completely free the function selection bridge of the movement 7 and the ring 4 is locked in the working position. This position makes it possible to adjust or to carry out the commands on the movement of the watch on the one hand by activating one of the push-buttons 29 (shown in FIG. figure 11 ) and secondly by turning the crown in one direction or the other according to the adjustment process specific to the movement of the watch which will be described later.

Depuis la position de travail représentée à la figure 8, le passage à la position de repos dans laquelle la couronne est escamotée se fait ensuite de la manière suivante.From the work position represented at figure 8 the transition to the rest position in which the crown is retracted is then done in the following manner.

Sous l'effet d'une pression imposée par l'utilisateur sur la couronne, la bague d'indexation 15 coulisse à l'intérieur du tube crantée 13 jusqu'à son extrémité inférieure pour rejoindre la position basse. Lors du passage par la position basse, les dents de la bague d'indexation 15 viennent indexer les dents de la bague crantée 12 ce qui provoque une premier rotation de la bague d'indexation 15. Les dents de la bague d'indexation 15 ne sont donc plus exactement en face des rainures 21 du tube cranté 13. Ensuite, lorsque l'utilisateur relâche la pression sur la couronne, les dents de la bague d'indexation 15 viennent indexer celles du tube cranté 13 ce qui provoque une deuxième rotation de la bague d'indexation et a pour effet de mettre les dents de la bague d'indexation 15 en face des nervures 22 du tube cranté 13. La bague d'indexation est désormais bloquée contre l'extrémité inférieure du tube cranté 13 et la couronne est en position de repos.Under the effect of a pressure imposed by the user on the crown, the indexing ring 15 slides inside the toothed tube 13 to its lower end to reach the lower position. When passing through the low position, the teeth of the indexing ring 15 index the teeth of the toothed ring 12 which causes a first rotation of the indexing ring 15. The teeth of the indexing ring 15 do not are therefore more exactly opposite the grooves 21 of the notched tube 13. Then, when the user releases the pressure on the ring gear, the teeth of the indexing ring 15 come to index those of the notched tube 13 which causes a second rotation of the indexing ring and has the effect of putting the teeth of the indexing ring 15 in front of the ribs 22 of the notched tube 13. The ring indexing is now locked against the lower end of the notched tube 13 and the crown is in the rest position.

La figure 9 représente une vue de dessus du pont de sélection de fonction du mouvement sans la couronne escamotable.The figure 9 represents a top view of the function selection bridge of the movement without the retractable crown.

Dans la boîte 2 sont fixées plusieurs bascules 23 qui permettent, en fonction de pressions effectuées par l'utilisateur sur des poussoirs 29 (représentés à la figure 11) d'agir sur les bascules 23 afin de régler ou de commander le mouvement de la montre. Les poussoirs de la montre agissent sur les bascules 23 par l'intermédiaire de tiges ayant une extrémité conique. Par soucis de clarté, seule l'extrémité inférieure conique 24 de ces tiges est représentée à la figure 9.In the box 2 are fixed several flip-flops 23 which, as a function of pressures made by the user on push-buttons 29 (shown in FIG. figure 11 ) to act on the latches 23 to adjust or control the movement of the watch. The pushers of the watch act on the latches 23 by means of rods having a conical end. For the sake of clarity, only the conical lower end 24 of these rods is shown in FIG. figure 9 .

Dans un mode d'exécution préféré, la tige 3 a une section carrée mais on peut aussi envisager que la tige ait une section de forme plus généralement polygonale. La tige 3 est fixée dans le pont de sélection 7 qui comporte un trou 25 apte à recevoir le plongeur 9 lorsque la couronne est en position basse ou de repos et deux bras ressorts 27, 28.In a preferred embodiment, the rod 3 has a square section, but it can also be envisaged that the rod has a section of more generally polygonal shape. The rod 3 is fixed in the selection bridge 7 which has a hole 25 adapted to receive the plunger 9 when the crown is in the low or rest position and two spring arms 27, 28.

Dans un mode d'exécution préféré, sur la boîte sont fixés deux poussoirs 29 (représentés sur la figure 11), l'un situé en face de la position marquant 2h au cadran de la montre et l'autre situé en face de la position marquant 4h au cadran de la montre. Ces poussoirs agissent donc sur les bascules 23 et peuvent par ailleurs comporter plusieurs ressorts. Lorsque l'utilisateur induit une pression sur l'un ou l'autre des poussoirs 29 et lorsque la couronne 4 se trouve en position de travail, l'extrémité conique 24 de la tige relative au poussoir sur lequel l'utilisateur a pressé s'enfonce dans un trou usiné dans la bascule correspondante. Ceci induit un mouvement de rotation de la bascule qui à son tour induit un mouvement de rotation du pont de sélection de fonction du mouvement 7 et permet le réglage du mouvement d'horlogerie au moyen des engrenages 26 selon un processus de réglage et/ou de commande propre au mouvement de la montre. Toutefois, lorsque la couronne se trouve en position de travail mais que l'utilisateur n'a pressé aucun des poussoirs 29, le pont de sélection 7 et les bascules 23 sont en position neutre et rien ne se passe lorsque l'utilisateur tourne la couronne.In a preferred embodiment, on the box are fixed two pushers 29 (shown on the figure 11 ), one located opposite the position marking 2 o'clock on the dial of the watch and the other located opposite the position marking 4 o'clock on the dial of the watch. These pushers therefore act on the latches 23 and can also have several springs. When the user induces pressure on one or other of the pushers 29 and when the ring 4 is in the working position, the conical end 24 of the rod relative to the pusher on which the user has pressed s' pushes into a hole machined in the corresponding rocker. This induces a rotational movement of the rocker which in turn induces a rotational movement of the function selection bridge of the movement 7 and allows the adjustment of the clockwork movement by means of the gears 26 according to an adjustment process and / or command specific to the movement of the watch. However, when the crown is in the working position but the user has not pressed any of the pushers 29, the selection bridge 7 and the rockers 23 are in the neutral position and nothing happens when the user turns the crown .

La figure 10A représente une vue en transparence de l'élément plongeur 9 lorsque la couronne 4 est en position de repos.The figure 10A represents a transparency view of the plunger element 9 when the crown 4 is in the rest position.

En position de repos, le plongeur 9 empêche toute rotation du pont de sélection de fonction du mouvement 7. Comme décrit précédemment, en position de repos, la couronne 4 est escamotée et l'extrémité conique du plongeur est logée dans le trou 25 prévu à cet effet sur le pont de sélection de fonction du mouvement 7. Le pont est en position neutre et les engrenages 26 du pont de sélection de fonction du mouvement 7 ne sont pas en contact avec le mouvement d'horlogerie.In the rest position, the plunger 9 prevents any rotation of the function selection bridge of the movement 7. As previously described, in the rest position, the ring 4 is retracted and the conical end of the plunger is housed in the hole 25 provided in FIG. this effect on the function selection bridge of the movement 7. The bridge is in the neutral position and the gears 26 of the function selection bridge of the movement 7 are not in contact with the clockwork movement.

Le fait qu'en position de repos, le plongeur 9 neutralise tout mouvement du pont de sélection de fonction du mouvement 7 permet également d'économiser l'énergie du mouvement d'horlogerie et de prolonger la réserve de marche de ce dernier. En effet, en position de repos, le pont de sélection de fonction du mouvement 7 est en position neutre et ses engrenages 26 ne sont pas actifs. Il n'y a donc aucun frottement entre les engrenages 26 et ceux du mouvement et donc aucune perte d'énergie à ce niveau là.The fact that in the rest position, the plunger 9 neutralizes any movement of the function selection bridge of the movement 7 also saves the energy of the watch movement and extend the power reserve of the latter. Indeed, in the rest position, the function of the function selection bridge 7 is in the neutral position and its gears 26 are not active. There is therefore no friction between the gears 26 and those of the movement and therefore no loss of energy at this level.

La figure 10B représente une vue schématique du pont de sélection de fonction du mouvement 7 lorsque la couronne 4 se trouve en position de repos. Le plongeur 9 est logé dans le trou 25 du pont de sélection de fonction du mouvement 7 et empêche toute rotation de celui-ci. En cas de mise en fonction d'un des poussoirs 29, c'est l'un des bras ressort 27, 28 du pont de sélection de fonction du mouvement 7 qui se déforme et empêche la rotation de ce dernier.The figure 10B represents a schematic view of the function selection bridge of the movement 7 when the ring 4 is in the rest position. The plunger 9 is housed in the hole 25 of the function selection bridge of the movement 7 and prevents any rotation thereof. If one of the pushers 29 is turned on, it is one of the spring arms 27, 28 of the function selection bridge of the movement 7 which deforms and prevents rotation of the latter.

La figure 10C représente une vue schématique du plongeur 9 lorsque la couronne 4 est en position de travail et qu'une pression a été appliquée sur l'un des poussoirs 29. A cet instant, le plongeur n'est plus complètement en face du trou 25 du pont 7.The Figure 10C is a diagrammatic view of the plunger 9 when the crown 4 is in the working position and a pressure has been applied to one of the pushers 29. At this time, the plunger is no longer completely opposite the hole 25 of the bridge 7.

La figure 10D représente une vue schématique du plongeur 9 lorsque la couronne 4 est en position basse. L'extrémité conique du plongeur 9 s'enfonce dans le trou 25 du pont 7 ce qui contribue à ramener le pont en position neutre. Ainsi, lorsque l'utilisateur relâche la pression sur la couronne, le pont est en position neutre et le plongeur est logé dans le trou. Comme décrit précédemment, la couronne 4 est à cet instant débrayée et tous les engrenages 26 du pont 7 sont alors inactifs ce qui contribue à économiser l'énergie du mouvement et prolonge la réserve de marche. Le passage de la position de travail à la position de repos et vice-versa se fait toujours en passant par la position basse. Dans tous les cas, le passage par la position basse permet donc de remettre le pont de sélection de fonction du mouvement 7 à la position neutre.The figure 10D represents a schematic view of the plunger 9 when the crown 4 is in the low position. The conical end of the plunger 9 sinks into the hole 25 of the bridge 7 which contributes to bring the bridge to the neutral position. So when the user releases the pressure on the crown, the bridge is in neutral position and the plunger is housed in the hole. As previously described, the crown 4 is at this moment disengaged and all the gears 26 of the bridge 7 are then inactive which contributes to saving the energy of the movement and extends the power reserve. The transition from the working position to the rest position and vice versa is always going through the low position. In all cases, the passage through the low position therefore allows to reset the function selection bridge of the movement 7 to the neutral position.

La figure 11 représente une vue de dessus du premier mode d'exécution du dispositif de réglage et/ou de commande selon l'invention dans lequel le dispositif de réglage et /ou de commande 1 est implanté sur la face supérieure d'une boîte de montre 2, autrement dit du côté de la lunette. Outre les composants usuels, la boîte de montre de montre comporte une couronne de réglage et/ou de commande escamotable 4 et un ou plusieurs poussoirs 29. De préférence, la boîte de montre 2 comprend deux poussoirs 29 dont l'un est situé en face de la position marquant deux heures au cadran de la montre et l'autre en face de la position marquant quatre heures.The figure 11 represents a view from above of the first embodiment of the adjustment and / or control device according to the invention in which the adjustment and / or control device 1 is implanted on the upper face of a watch case 2, in other words, the side of the telescope. In addition to the usual components, the watch watch case comprises an adjustable crown and / or retractable control 4 and one or more pushers 29. Preferably, the watch case 2 comprises two pushers 29, one of which is located opposite from the position marking two hours on the dial of the watch and the other opposite the position marking four hours.

Dans un autre mode d'exécution, il est aussi possible que le dispositif de réglage soit fixé dans un logement creusé dans la carrure radialement à la boîte de montre.In another embodiment, it is also possible that the adjustment device is fixed in a housing hollowed in the caseband radially to the watch case.

Dans la description précédente du premier mode d'exécution, le dispositif de réglage et/ou de commande est fixé dans une montre mécanique. On peut aussi envisager que le dispositif de réglage soit plus généralement implanté dans une pièce d'horlogerie, notamment une horloge, un réveil ou tout autre pièce d'horlogerie mécanique.In the previous description of the first embodiment, the adjustment and / or control device is fixed in a mechanical watch. It is also conceivable that the adjustment device is more generally located in a timepiece, including a clock, an alarm clock or any other mechanical timepiece.

Grâce au dispositif de commande et/ou de réglage selon l'invention, la couronne de réglage est escamotée la plupart du temps et ne risque plus de se tordre ou de rompre.Thanks to the control device and / or adjustment according to the invention, the adjusting ring is retracted most of the time and no longer likely to bend or break.

De plus, grâce au dispositif de commande et/ou de réglage selon l'invention, la couronne n'est plus saillante et ne risque pas d'abimer vêtements ou bijoux.In addition, thanks to the control device and / or adjustment according to the invention, the crown is no longer salient and does not risk to damage clothing or jewelry.

Le dispositif de réglage et/ou de commande selon l'invention permet également d'éliminer la gêne occasionnée par la présence d'une couronne saillante.The adjustment and / or control device according to the invention also eliminates the inconvenience caused by the presence of a projecting ring.

Finalement, le dispositif de réglage et/ou de commande selon l'invention permet, par le fait que la couronne soit escamotée la plupart du temps, de ne pas rompre la continuité de la structure circulaire de la montre ce qui contribue largement à améliorer l'esthétique de la montre.Finally, the adjustment and / or control device according to the invention makes it possible, in that the crown is retracted most of the time, not to break the continuity of the circular structure of the watch, which largely contributes to improving the aesthetics of the watch.
