Description

La présente invention concerne un organe de commande pour mécanisme horloger. La présente invention concerne en particulier un organe de commande permettant la commande simultanée d'une pluralité d'éléments du mécanisme horloger. Selon certaines formes d'exécution, l'organe de commande de la présente invention est une roue à colonnes pour mécanisme de chronographe.The present invention relates to a control member for a watch mechanism. The present invention relates in particular to a control member allowing the simultaneous control of a plurality of elements of the watch mechanism. According to certain embodiments, the control member of the present invention is a column wheel for a chronograph mechanism.

Certains mécanismes horlogers, comme par exemple les mécanismes de chronographe ou certains mécanismes d'affichage, nécessitent la commande simultanée de plusieurs éléments du mécanisme, par exemple des compteurs ou des organes d'affichage. Afin de garantir leur synchronisation, ces éléments sont de préférence commandés à l'aide d'un organe de commande unique, par exemple à l'aide d'une roue à colonnes ou d'une came. L'organe de commande est actionné par exemple à la demande à l'aide d'un bouton poussoir accessible à un utilisateur, au passage par un mouvement horloger, ou par tout autre moyen approprié. La commande ainsi reçue est alors retransmise par l'organe de commande de préférence à tous les éléments du mécanisme horloger devant être actionnés à leur tour. La commande correspond par exemple au démarrage ou à l'arrêt d'un chronométrage, ou à une remise à zéro des compteurs, dans le cas d'un mécanisme de chronographe, à une modification d'un affichage dans le cas d'un mécanisme d'affichage, ou à toute autre commande/information devant être transmise au mécanisme horloger pour son bon fonctionnement.Certain watch mechanisms, such as for example chronograph mechanisms or certain display mechanisms, require the simultaneous control of several elements of the mechanism, for example counters or display members. In order to guarantee their synchronization, these elements are preferably controlled using a single control member, for example using a column wheel or a cam. The control member is actuated for example on demand using a push button accessible to a user, passing by a watch movement, or by any other appropriate means. The command thus received is then retransmitted by the control member preferably to all the elements of the watch mechanism which must be actuated in turn. The command corresponds for example to starting or stopping timing, or to resetting the counters to zero, in the case of a chronograph mechanism, to modifying a display in the case of a mechanism display, or any other command/information that must be transmitted to the watch mechanism for its proper functioning.

Pour retransmettre la commande simultanément à plusieurs éléments, l'organe de commande comprend généralement une roue montée mobile en rotation autour d'un axe et plusieurs surfaces de commande solidaires en rotation de la roue, généralement situées en saillie sur la planche de la roue. Les surfaces de commande sont par exemple les surfaces de colonnes, la périphérie à rayon variable d'une came, etc. La roue est tournée par exemple d'un pas prédéfini à chaque nouvelle activation de l'organe de commande. Les éléments du mécanisme à commander comprennent généralement chacun un palpeur ou un suiveur pour coopérer avec les surfaces de commande de l'organe de commande. Un changement de position de la surface de commande en regard du palpeur ou du suiveur, voire l'absence de surface de commande, à l'issue de la rotation de l'organe de commande génère une réponse appropriée de l'élément correspondant, qui provoque par exemple le démarrage d'un compteur de temps, la modification d'un affichage, une remise à zéro du mécanisme, etc. Les palpeurs ou suiveurs des différents éléments commandés par l'organe de commande sont généralement répartis autour de l'organe de commande et accèdent aux surfaces de commande chacun selon une position angulaire déterminée.To retransmit the command simultaneously to several elements, the control member generally comprises a wheel mounted movable in rotation around an axis and several control surfaces integral in rotation with the wheel, generally located projecting from the plate of the wheel. Control surfaces are, for example, column surfaces, the variable radius periphery of a cam, etc. The wheel is turned for example from a predefined pitch to each new activation of the control unit. The elements of the mechanism to be controlled generally each include a feeler or a follower to cooperate with the control surfaces of the control member. A change in position of the control surface facing the probe or the follower, or even the absence of a control surface, following rotation of the control member generates an appropriate response from the corresponding element, which causes for example the starting of a time counter, the modification of a display, a reset of the mechanism, etc. The feelers or followers of the different elements controlled by the control member are generally distributed around the control member and access the control surfaces each according to a determined angular position.

Un inconvénient d'un tel organe de commande est qu'il est difficile de ménager un accès aux surfaces de commande à un grand nombre d'éléments à commander, en particulier dans l'espace souvent limité d'une pièce d'horlogerie. Le nombre d'éléments pouvant être commandés par un même organe de commande est donc limité par l'espace disponible autour de ce dernier.A disadvantage of such a control member is that it is difficult to provide access to the control surfaces for a large number of elements to be controlled, in particular in the often limited space of a timepiece. The number of elements that can be controlled by the same control member is therefore limited by the space available around the latter.

Un but de la présente invention est de proposer un organe de commande pour mécanisme horloger permettant de commander simultanément un grand nombre d'éléments du mécanisme.An aim of the present invention is to propose a control member for a watch mechanism making it possible to simultaneously control a large number of elements of the mechanism.

Ce but et d'autres avantages sont atteints par un organe de commande pour mécanisme horloger comprenant une couronne à denture intérieure pour l'entraînement en rotation de l'organe de commande et une pluralité de surfaces de commande en saillie sur la surface supérieure et/ou inférieure de la couronne et orientées vers l'intérieur de l'organe de commande.This aim and other advantages are achieved by a control member for a watch mechanism comprising a crown with internal teeth for driving the control member in rotation and a plurality of control surfaces projecting from the upper surface and/or or lower of the crown and oriented towards the inside of the control member.

La denture pour l'entraînement de l'organe de commande étant localisée sur la périphérie intérieure de la couronne, le mécanisme d'entraînement de l'organe de commande peut être au moins partiellement disposé à l'intérieur de l'organe de commande. Les surfaces de commande étant orientées vers l'intérieur de l'organe de commande, les éléments du mécanisme horloger destinés à être commandés par l'organe de commande, et qui doivent accéder à ces surfaces de commande, peuvent également être au moins partiellement disposés à l'intérieur de l'organe de commande. L'organe de commande de l'invention ne nécessitant aucun entraînement ni aucun accès aux surfaces de commande depuis sa périphérie extérieure, son diamètre peut être maximisé jusqu'à correspondre pratiquement au diamètre extérieur du mécanisme horloger auquel il est destiné. L'organe de commande peut alors être intégré au mécanisme horloger de manière à suivre la périphérie de ce dernier sur tout le tour du mécanisme horloger, permettant ainsi de distribuer les surfaces de commande à la périphérie du mécanisme horloger. Les surfaces de commande de l'organe de commande de l'invention sont ainsi accessibles facilement depuis un grand nombre de positions dans le mécanisme horloger. Le diamètre de l'organe de commande étant maximal, le nombre de surfaces de commande en saillie sur la surface supérieure et/ou inférieure peut également être relativement important, permettant un accès simultané aux surfaces de commande à un grand nombre d'éléments.The teeth for driving the control member being located on the inner periphery of the crown, the drive mechanism of the control member can be at least partially arranged inside the control member. The control surfaces being oriented towards the inside of the control member, the elements of the watch mechanism intended to be controlled by the control member, and which must access these control surfaces, can also be at least partially arranged inside the control member. Since the control member of the invention does not require any drive or any access to the control surfaces from its outer periphery, its diameter can be maximized until it practically corresponds to the outer diameter of the watch mechanism for which it is intended. The control member can then be integrated into the watch mechanism so as to follow the periphery of the latter all the way around the watch mechanism, thus making it possible to distribute the control surfaces to the periphery of the watch mechanism. The control surfaces of the control member of the invention are thus easily accessible from a large number of positions in the watch mechanism. The diameter of the control member being maximum, the number of control surfaces projecting on the upper and/or lower surface can also be relatively large, allowing simultaneous access to the control surfaces of a large number of elements.

Selon une forme d'exécution de l'invention, l'organe de commande est une roue à colonnes annulaire pour mécanisme de chronographe. Les surfaces de commande sont alors situées sur une pluralité de colonnes formant des créneaux sur la surface supérieure et/ou inférieure de la couronne.According to one embodiment of the invention, the control member is an annular column wheel for a chronograph mechanism. The control surfaces are then located on a plurality of columns forming slots on the upper and/or lower surface of the crown.

Selon une autre forme d'exécution, les surfaces de commande de l'organe de commande de l'invention sont situées sur la périphérie intérieure d'une came située en saillie sur la surface supérieure et/ou inférieure de la couronne.According to another embodiment, the control surfaces of the control member of the invention are located on the inner periphery of a cam located projecting on the upper and/or lower surface of the crown.

Selon certaines formes d'exécution de l'invention, la denture intérieure comprend des dents en dents de scie formant un rochet. Cela permet typiquement d'entraîner l'organe de commande pas-à-pas dans un sens de rotation défini par la forme des dents de scie.According to certain embodiments of the invention, the internal teeth comprise sawtooth teeth forming a ratchet. This typically makes it possible to drive the control member step by step in a direction of rotation defined by the shape of the saw teeth.

Le but évoqué plus haut et d'autres avantages sont atteints également par un mécanisme horloger comprenant un tel organe de commande, un mécanisme d'entraînement pour entraîner l'organe de commande en rotation et une pluralité d'éléments destinés à être commandés par l'organe de commande.The aim mentioned above and other advantages are also achieved by a watch mechanism comprising such a control member, a mechanism drive to drive the control member in rotation and a plurality of elements intended to be controlled by the control member.

De préférence, l'organe de commande suit la périphérie du mécanisme horloger, au moins une partie du mécanisme d'entraînement et au moins une partie de chaque élément de la pluralité d'éléments du mécanisme horloger destinés à être commandés par l'organe de commande étant disposés à l'intérieur de l'organe de commande.Preferably, the control member follows the periphery of the watch mechanism, at least part of the drive mechanism and at least part of each element of the plurality of elements of the watch mechanism intended to be controlled by the control member. control being arranged inside the control member.

L'organe de commande est par exemple monté mobile en rotation sur une platine du mécanisme horloger.The control member is for example mounted to move in rotation on a plate of the watch mechanism.

L'organe de commande est par exemple guidé en rotation par au moins un galet et/ou au moins une goupille et/ou au moins un tenon disposé sur la platine à la périphérie extérieure de l'organe de commande.The control member is for example guided in rotation by at least one roller and/or at least one pin and/or at least one tenon arranged on the plate at the outer periphery of the control member.

Selon une forme d'exécution, le mécanisme horloger est un mécanisme de chronographe et l'organe de commande est une roue à colonnes annulaire.According to one embodiment, the watch mechanism is a chronograph mechanism and the control member is an annular column wheel.

Le but évoqué plus haut et d'autres avantages sont atteints aussi par une pièce d'horlogerie comprenant un tel mécanisme horloger.The aim mentioned above and other advantages are also achieved by a timepiece comprising such a watch mechanism.

The crown 2 includes internal teeth 20 on its interior periphery for its rotational drive. The internal teeth 20 comprise, for example, sawtooth teeth forming a ratchet. According to the illustrated embodiment, the control member 1 further comprises columns 3 projecting from the upper surface 21 of the crown 2. The columns 3 are preferably identical to each other and distributed regularly over the circumference of the crown 2, forming slots on the upper surface 21 of the crown 2.

Un intérieur 4 de l'organe de commande 1 est délimité par la denture intérieure 20 et les colonnes 3 de l'organe de commande 1. L'intérieur 4 de l'organe de commande 1 est de préférence vide pour permettre d'y loger au moins une partie du mécanisme horloger auquel l'organe de commande 1 est destiné. Selon l'invention, les surfaces des colonnes 3 orientées vers l'intérieur 4 de l'organe de commande 1 constituent les surfaces de commande 30 de l'organe de commande 1 qui sont par conséquent accessibles depuis l'intérieur 4 de l'organe de commande 1. L'intérieur 4 de l'organe de commande 1 permet de loger au moins partiellement un mécanisme d'entraînement destiné à coopérer avec la denture intérieure 20 pour mettre en rotation l'organe de commande 1, ainsi que les palpeurs et/ou suiveurs des éléments du mécanisme horloger destinés à être commandés par l'organe de commande 1. De préférence, l'organe de commande 1 est dimensionné pour suivre la périphérie du mécanisme horloger auquel il est destiné afin de maximiser le diamètre de l'intérieur 4 de l'organe de commande 1.An interior 4 of the control member 1 is delimited by the internal teeth 20 and the columns 3 of the control member 1. The interior 4 of the control member 1 is preferably empty to accommodate at least part of the watch mechanism for which the control member 1 is intended. According to the invention, the surfaces of the columns 3 oriented towards the interior 4 of the control member 1 constitute the control surfaces 30 of the control member 1 which are therefore accessible from the interior 4 of the member control member 1. The interior 4 of the control member 1 makes it possible to accommodate at least partially a drive mechanism intended to cooperate with the internal teeth 20 to rotate the control member 1, as well as the feelers and / or followers of the elements of the watch mechanism intended to be controlled by the control member 1. Preferably, the control member 1 is dimensioned to follow the periphery of the watch mechanism for which it is intended in order to maximize the diameter of the interior 4 of the control member 1.

L'organe de commande 1 est de préférence destiné à être monté mobile en rotation sur un support du mécanisme horloger, par exemple sur une platine du mécanisme horloger non représenté à la figure 1. L'organe de commande 1 est par exemple partiellement logé, par exemple par sa surface inférieure 22, dans une rainure annulaire du support dans laquelle il glisse au cours de sa rotation. La surface inférieure 22 de l'organe de commande 1 est de préférence lisse, de manière à minimiser la résistance à la rotation de l'organe de commande 1 sur le support. Le profil de la surface inférieure 22 de l'organe de commande 1 est par exemple complémentaire à un profil du support de manière à guider l'organe de commande 1 en rotation sur le support. De préférence, la circonférence extérieure 23 de la couronne 2 est également lisse. Optionnellement, des éléments de guidage sont disposés sur le support à la périphérie de l'organe de commande 1 pour guider la rotation de l'organe de commande 1 et/ou le maintenir sur le support. Les éléments de guidage comprennent par exemple une ou plusieurs goupilles et/ou un ou plusieurs galets et/ou un ou plusieurs tenons. Selon d'autres formes d'exécution, les éléments de guidage se trouvent à l'intérieur de l'organe de commande de l'invention, par exemple entre une platine sur laquelle l'organe de commande est disposé mobile en rotation et la pointe des dents de la denture intérieure. Cela permet de réduire au minimum, voire éliminer complètement, l'espace libre nécessaire autour de l'organe de commande et ainsi maximiser le diamètre de ce dernier.The control member 1 is preferably intended to be mounted movable in rotation on a support of the watch mechanism, for example on a plate of the watch mechanism not shown in the figure 1 . The control member 1 is for example partially housed, for example by its lower surface 22, in an annular groove of the support in which it slides during its rotation. The lower surface 22 of the control member 1 is preferably smooth, so as to minimize the resistance to rotation of the control member 1 on the support. The profile of the lower surface 22 of the control member 1 is for example complementary to a profile of the support so as to guide the control member 1 in rotation on the support. Preferably the outer circumference 23 of crown 2 is also smooth. Optionally, guide elements are arranged on the support at the periphery of the control member 1 to guide the rotation of the control member 1 and/or maintain it on the support. The guide elements include for example one or more pins and/or one or more rollers and/or one or more tenons. According to other embodiments, the guide elements are located inside the control member of the invention, for example between a plate on which the control member is arranged to move in rotation and the tip teeth of the internal teeth. This makes it possible to reduce to a minimum, or even completely eliminate, the necessary free space around the control member and thus maximize the diameter of the latter.

La figure 2 illustre un exemple de mécanisme horloger 5 comprenant l'organe de commande 1 de l'invention selon la forme d'exécution illustrée à la figure 1.There figure 2 illustrates an example of a watch mechanism 5 comprising the control member 1 of the invention according to the embodiment illustrated in figure 1 .

Dans l'exemple illustré, le mécanisme horloger 5 est un mécanisme de chronographe et l'organe de commande 1 est une roue à colonnes annulaire. Selon cette forme d'exécution, l'organe de commande 1 est posé sur la platine 50 du mécanisme horloger 5. L'organe de commande 1 est par exemple posé sur la platine 50 avec sa surface inférieure contre la platine 50. Afin de minimiser les frottements lors de sa rotation, l'organe de commande 1 est par exemple posé sur une ou plusieurs pierres, non visibles sur les figures, en saillie à la surface de la platine 50 et réparties en regard de la surface inférieure de l'organe de commande 1. Selon le mode de réalisation illustré, le mécanisme horloger 5 comprend des éléments de guidage répartis sur la platine 50 à la périphérie de l'organe de commande 1 pour le guider en rotation et pour le maintenir sur la platine 50. Les éléments de guidage comprennent par exemple cinq galets 6 montés de préférence chacun sur un bras qui les ramène élastiquement contre la périphérie extérieure 23 de l'organe de commande 1. Les cinq galets 6 sont de préférence répartis régulièrement à la périphérie de l'organe de commande 1. Le nombre et la nature des éléments de guidage peuvent être différents dans le cadre de l'invention. Ils sont choisis de préférence en fonction de la place disponible autour de l'organe de commande, du type de guidage et/ou de fixation souhaité, etc.In the example illustrated, the watch mechanism 5 is a chronograph mechanism and the control member 1 is an annular column wheel. According to this embodiment, the control member 1 is placed on the plate 50 of the watch mechanism 5. The control member 1 is for example placed on the plate 50 with its lower surface against the plate 50. In order to minimize friction during its rotation, the control member 1 is for example placed on one or more stones, not visible in the figures, projecting from the surface of the plate 50 and distributed facing the lower surface of the member control element 1. According to the illustrated embodiment, the watch mechanism 5 comprises guide elements distributed on the plate 50 at the periphery of the control member 1 to guide it in rotation and to maintain it on the plate 50. The guide elements comprise for example five rollers 6 preferably each mounted on an arm which brings them elastically against the outer periphery 23 of the control member 1. The five rollers 6 are preferably distributed regularly around the periphery of the control member. command 1. The number and nature of the guide elements may be different in the context of the invention. They are preferably chosen according to the space available around the control member, the type of guidance and/or fixing desired, etc.

Le mécanisme horloger 5 comprend de préférence un mécanisme d'entraînement pour entraîner l'organe de commande 1 en rotation, par exemple à la demande au moyen d'un bouton poussoir ou tout autre élément d'activation accessible à un utilisateur et/ou au passage à des instants déterminés par un mouvement horloger. Selon l'invention, le mécanisme d'entraînement est configuré pour entraîner l'organe de commande 1 à l'aide de la denture intérieure 20. Le mécanisme d'entraînement entraîne ainsi l'organe de commande 1 depuis l'intérieur de ce dernier. Le mécanisme d'entraînement est de préférence au moins partiellement disposé à l'intérieur de l'organe de commande 1. Le mécanisme d'entraînement comprend par exemple un bec 51 situé à l'intérieur de l'organe de commande 1 pour tourner l'organe de commande d'un pas dans une direction donnée à chaque activation, le déplacement angulaire au cours d'un pas correspondant par exemple à l'écartement entre deux dents adjacentes de la denture intérieure 20. D'autres modes d'entraînement sont cependant possibles dans le cadre de l'invention. Selon les modes d'exécution, le mécanisme d'entraînement entraîne par exemple l'organe de commande de manière continue et/ou en alternance dans les deux sens de rotation, ou selon toute autre séquence de mouvements rotatifs adaptée.The watch mechanism 5 preferably comprises a drive mechanism for driving the control member 1 in rotation, for example on demand by means of a push button or any other activation element accessible to a user and/or to the user. transition to moments determined by a clock movement. According to the invention, the drive mechanism is configured to drive the control member 1 using the internal teeth 20. The drive mechanism thus drives the control member 1 from inside the latter . The drive mechanism is preferably at least partially arranged inside the control member 1. The drive mechanism comprises for example a nozzle 51 located inside the control member 1 to turn the 'control member of a step in a given direction at each activation, the angular displacement during a step corresponding for example to the spacing between two adjacent teeth of the internal teeth 20. Other drive modes are however possible within the framework of the invention. Depending on the modes of execution, the drive mechanism drives the control member, for example, continuously and/or alternately in the two directions of rotation, or according to any other suitable sequence of rotary movements.

De préférence, le mécanisme horloger 5 comprend en outre un sautoir 52 pour maintenir l'organe de commande 1 dans une position angulaire déterminée après chaque rotation. De préférence, le sautoir 52 coopère avec la denture 20 de l'organe de commande 1 pour maintenir l'organe de commande 1 en position.Preferably, the watch mechanism 5 further comprises a jumper 52 to maintain the control member 1 in a determined angular position after each rotation. Preferably, the jumper 52 cooperates with the teeth 20 of the control member 1 to hold the control member 1 in position.

Selon la forme d'exécution illustrée, le mécanisme horloger 5 comprend en outre des éléments de limitation pour limiter le déplacement axial de l'organe de rotation 1 par rapport à la platine 50. Les éléments de limitation sont par exemple des vis 7 dont la tête comporte une portion tronquée et qui sont tournées d'un demi-tour pour limiter le déplacement axial de l'organe de commande 1 par rapport à la platine 50, ou pour libérer l'organe de commande 1 et le détacher de la platine 50. Selon la forme d'exécution illustrée, les éléments de limitation comprennent également une butée 70 vissé sur la platine 50 à la périphérie de l'organe de commande 1 pour limiter les déplacements axiaux de l'organe de commande 1 par rapport à la platine 50. Les éléments de limitation sont de préférence répartis régulièrement sur la platine 50 à la périphérie de l'organe de commande 1. D'autres types et nombres d'éléments de limitation sont cependant envisageable dans le cadre de l'invention. Le choix et la disposition des éléments de limitation dépendent par exemple de la place à disposition autour de l'organe de commande 1, de la surface de l'organe de commande 1 avec laquelle les éléments de limitation coopèrent, etc.According to the illustrated embodiment, the watch mechanism 5 further comprises limitation elements to limit the axial movement of the rotation member 1 relative to the plate 50. The limitation elements are for example screws 7 whose head has a truncated portion and which are turned by one half-turn to limit the axial movement of the control member 1 relative to the plate 50, or to release the control member 1 and detach it from the plate 50. According to the illustrated embodiment, the elements of limitation also include a stop 70 screwed onto the plate 50 at the periphery of the control member 1 to limit the axial movements of the control member 1 relative to the plate 50. The limitation elements are preferably distributed regularly over the plate 50 at the periphery of the control member 1. Other types and numbers of limiting elements are however possible within the framework of the invention. The choice and arrangement of the limiting elements depend for example on the space available around the control member 1, on the surface of the control member 1 with which the limiting elements cooperate, etc.

Selon l'invention, les surfaces de commande de l'organe de commande 1 sont orientées vers l'intérieur de l'organe de commande 1 et sont donc accessibles depuis cet intérieur. Chaque élément du mécanisme horloger 5 devant être commandé par l'organe de commande 1 est ainsi de préférence au moins partiellement disposé à l'intérieur de l'organe de commande 1 et comprend par exemple un palpeur et/ou un suiveur pour coopérer avec les surfaces de commande depuis l'intérieur de l'organe de commande 1 afin de déclencher une opération correspondant à la commande ou l'information lue par le palpeur ou le suiveur sur la surface de commande. Dans le cas de la roue à colonnes illustrée par les figures, par exemple, la commande ou l'information perçue par un élément commandé par l'organe de commande 1 peut prendre deux états : un premier état correspondant à la présence d'une colonne, et donc d'une surface de commande, en regard du palpeur ou suiveur correspondant, et un deuxième état correspondant à l'absence de colonne, et donc de surface de commande, en regard du palpeur ou suiveur correspondant.According to the invention, the control surfaces of the control member 1 are oriented towards the interior of the control member 1 and are therefore accessible from this interior. Each element of the watch mechanism 5 to be controlled by the control member 1 is thus preferably at least partially arranged inside the control member 1 and comprises for example a feeler and/or a follower to cooperate with the control surfaces from inside the control member 1 in order to trigger an operation corresponding to the command or the information read by the probe or the follower on the control surface. In the case of the column wheel illustrated by the figures, for example, the command or the information perceived by an element controlled by the control member 1 can take two states: a first state corresponding to the presence of a column , and therefore a control surface, facing the corresponding probe or follower, and a second state corresponding to the absence of column, and therefore of a control surface, facing the corresponding probe or follower.

Il est toutefois envisageable dans le cadre de l'invention de configurer l'organe de commande pour transmettre une commande ou une information pouvant prendre plus de deux états, par exemple en disposant sur l'organe de commande des surfaces de commande à des distances différentes du centre de l'organe de commande et/ou des espaces vides sans surface de commande, chaque distance ou vide correspondant à une commande ou information différente lue par les différents palpeurs et/ou suiveurs et interprétée par les éléments commandés correspondants. Selon certaines formes d'exécution, au moins deux surfaces de commande à des distances radiales différentes sont par exemple formées sur chaque colonne.It is however possible in the context of the invention to configure the control member to transmit a command or information capable of taking more than two states, for example by arranging on the control member control surfaces at different distances from the center of the control member and/or empty spaces without a control surface, each distance or void corresponding to a different command or information read by the different probes and/or trackers and interpreted by the corresponding controlled elements. According to certain embodiments, at least two control surfaces at different radial distances are for example formed on each column.

Selon la forme d'exécution illustrée par les figures 1 et 2, l'organe de commande 1 est une roue à colonnes annulaire destinée à être intégrée à un mécanisme de chronographe à trois temps : le nombre de dents de la denture intérieure 20 de l'organe de commande 1 est le triple du nombre de colonnes 3. Selon d'autres formes d'exécution de l'invention, l'organe de commande est une roue à colonnes annulaire destinée à être intégrée à un mécanisme de chronographe à deux temps et le nombre de dents de la denture intérieure de l'organe de commande est le double du nombre de colonnes.According to the form of execution illustrated by the figures 1 and 2 , the control member 1 is an annular column wheel intended to be integrated into a three-time chronograph mechanism: the number of teeth of the internal teeth 20 of the control member 1 is triple the number of columns 3 According to other embodiments of the invention, the control member is an annular column wheel intended to be integrated into a two-time chronograph mechanism and the number of teeth of the internal teeth of the member. order is double the number of columns.

Selon encore d'autres formes d'exécution, l'organe de commande comprend une came en saillie sur la surface supérieure de la couronne. La came comprend une surface périphérique intérieure orientée vers l'intérieur de l'organe de commande. Le rayon de la surface périphérique intérieure de la came est de préférence variable, formant ainsi une pluralité de surfaces de commande à des distances différentes du centre de l'organe de commande, chaque distance correspondant par exemple à une commande et/ou une information spécifique qui peut avoir une signification différente pour chaque élément du mécanisme horloger commandé par l'organe de commande.According to yet other embodiments, the control member comprises a cam projecting from the upper surface of the crown. The cam includes an interior peripheral surface oriented toward the interior of the control member. The radius of the interior peripheral surface of the cam is preferably variable, thus forming a plurality of control surfaces at different distances from the center of the control member, each distance corresponding for example to a specific command and/or information which can have a different meaning for each element of the watch mechanism controlled by the control member.

Selon l'invention, et en référence à la figure 1, la couronne 2 étant configurée pour être entraînée depuis l'intérieur 4 de l'organe de commande 1 et les surfaces de commande 30 étant configurées pour être accédées depuis l'intérieur 4 de l'organe de commande 1, le nombre de pièces à la périphérie extérieure de l'organe de commande 1 lors de son intégration dans un mécanisme horloger peut être limité aux seuls éventuels éléments de guidage pour le guider en rotation et/ou le maintenir axialement sur son support, par exemple sur la platine du mécanisme horloger. Le diamètre de l'organe de commande 1 peut ainsi être maximisé pour atteindre pratiquement le diamètre du mécanisme horloger auquel l'organe de commande 1 est destiné. L'organe de transmission 1 peut ainsi être intégré dans un mécanisme horloger de manière à couvrir l'ensemble de sa périphérie. L'organe de commande 1 annulaire est de préférence monté coaxial au mécanisme horloger. Les surfaces de commande 30 en saillie sur la surface supérieure de la couronne 2 peuvent ainsi être réparties sur toute la périphérie du mécanisme horloger, facilitant ainsi leur accès par un grand nombre d'éléments commandés du mécanisme horloger.According to the invention, and with reference to the figure 1 , the crown 2 being configured to be driven from the interior 4 of the control member 1 and the control surfaces 30 being configured to be accessed from the interior 4 of the control member 1, the number of parts to be the suburbs exterior of the control member 1 when it is integrated into a watch mechanism can be limited only to possible guide elements to guide it in rotation and/or maintain it axially on its support, for example on the plate of the watch mechanism. The diameter of the control member 1 can thus be maximized to practically reach the diameter of the watch mechanism for which the control member 1 is intended. The transmission member 1 can thus be integrated into a watch mechanism so as to cover its entire periphery. The annular control member 1 is preferably mounted coaxial with the watch mechanism. The control surfaces 30 projecting from the upper surface of the crown 2 can thus be distributed over the entire periphery of the watch mechanism, thus facilitating their access by a large number of controlled elements of the watch mechanism.

Avantageusement, lorsque le mécanisme horloger de l'invention est intégré dans une pièce d'horlogerie, par exemple dans une montre bracelet, l'organe de commande 1 est situé sous la lunette de la montre ou sous le support du verre de fond de boîte.Advantageously, when the watch mechanism of the invention is integrated into a timepiece, for example in a wristwatch, the control member 1 is located under the bezel of the watch or under the support of the case back glass .

Dans la description qui précède illustrée par les figures 1 et 2, l'organe de commande 1 est intégré dans le mécanisme horloger 5 avec la surface inférieure 22 de la couronne 2 en contact avec ou en regard d'un support du mécanisme horloger 5, les surfaces de commande 30 étant en saillie sur la surface supérieure 21 de la couronne 2 opposée à la surface inférieure 22. Il est cependant également envisageable dans le cadre de l'invention que les surfaces de commande soient en saillie sur la surface inférieure de l'organe de commande, ou sur la surface inférieure et sur la surface supérieure. L'organe de commande est alors intégré dans le mécanisme horloger avec l'extrémité distale des surfaces de commande en saillie sur la surface inférieure en contact avec ou en regard du support du mécanisme horloger, par exemple la platine. Lors de la rotation de l'organe de commande, l'extrémité distale des surfaces de commande en saillie sur la surface inférieure, par exemple le sommet des colonnes ou la surface inférieure de la came, glisse contre le support.In the preceding description illustrated by the figures 1 and 2 , the control member 1 is integrated into the watch mechanism 5 with the lower surface 22 of the crown 2 in contact with or facing a support of the watch mechanism 5, the control surfaces 30 being projecting from the upper surface 21 of the crown 2 opposite the lower surface 22. However, it is also possible in the context of the invention for the control surfaces to project from the lower surface of the control member, or from the lower surface and the upper surface. The control member is then integrated into the watch mechanism with the distal end of the control surfaces projecting from the lower surface in contact with or facing the support of the watch mechanism, for example the plate. When rotating the control member, the distal end of the projecting control surfaces on the bottom surface, for example the top of the columns or the bottom surface of the cam, slides against the support.
