Description

Domaine techniqueTechnical area

L'invention est relative à une montre pourvue d'au moins une fonction gérable de manière électronique et pourvue d'un organe de commande pour contrôler ladite fonction.The invention relates to a watch provided with at least one function which can be managed electronically and provided with a control member for controlling said function.

Arrière-plan technologiqueTechnological background

Les montres mécaniques ou électromécaniques comprennent de manière standard une tige-couronne qui permet de régler la position des aiguilles en tournant la couronne, ainsi que de remonter le barillet dans le cas d'une montre mécanique. Dans la plupart des cas, la couronne se trouve dans une position de repos proche de la boîte de la montre et il faut la tirer vers une position de réglage pour ajuster le temps et, le cas échéant, la date.Mechanical or electromechanical watches include as standard a stem-crown which makes it possible to adjust the position of the hands by turning the crown, as well as to wind the barrel in the case of a mechanical watch. In most cases, the crown is in a rest position close to the watch case and must be pulled to a setting position to adjust the time and, if applicable, the date.

De plus en plus des fonctions additionnelles sont prévues, tel qu'un affichage électronique d'informations personnelles et/ou géographiques, par exemple un agenda, des données fitness et de géolocalisation. Ceci est le cas également pour les montres équipées d'un mouvement mécanique, par exemple par l'ajout d'un module électronique comprenant un écran digital agencé sur une partie du cadran.More and more additional functions are provided, such as electronic display of personal and / or geographic information, for example a diary, fitness and geolocation data. This is also the case for watches equipped with a mechanical movement, for example by adding an electronic module comprising a digital screen arranged on part of the dial.

La présence des fonctions additionnelles susmentionnées requiert généralement des moyens de commande spécifiques, qui permettent par exemple de sélectionner une fonction, de naviguer dans un menu, etc.The presence of the above-mentioned additional functions generally requires specific control means, which make it possible, for example, to select a function, to navigate in a menu, etc.

Des montres électroniques ont été développées avec un organe de commande de type 'joystick' ou 'trackball'. Des exemples de ces solutions sont respectivement illustrés par les documents EP 1168113 et EP 0582150 . Mais on notera que ces solutions ne sont pas prévues pour une montre à remontage mécanique. Le document EP 0582150 décrit également une montre pourvue d'une tige-couronne ainsi que d'un dispositif 'trackball'. Le désavantage de cette dernière solution est que la présence de deux organes de commande séparés spatialement n'est pas toujours souhaitable d'un point de vue esthétique et/ou d'un point de vue économique étant donné que la boîte de montre est plus complexe à usiner. On remarquera aussi qu'une bonne étanchéité de la boîte de montre est plus difficile à obtenir avec les organes de commande de type 'joystick' ou 'trackball' décrits dans les documents antérieurs susmentionnés.Electronic watches have been developed with a control member of the 'joystick' or 'trackball' type. Examples of these solutions are respectively illustrated by the documents EP 1168113 and EP 0582150 . However, it should be noted that these solutions are not intended for a mechanical winding watch. The document EP 0582150 also describes a watch provided with a stem-crown as well as a 'trackball' device. The disadvantage of the latter solution is that the presence of two spatially separated control members is not always desirable from an aesthetic point of view and / or from an economic point of view given that the watch case is more complex to machine. It will also be noted that a good seal of the watch case is more difficult to obtain with the control members of the “joystick” or “trackball” type described in the above-mentioned prior documents.

Résumé de l'inventionSummary of the invention

L'invention vise à fournir une montre qui ne souffre pas des inconvénients décrits ci-dessus. Ce but est atteint par la montre selon les revendications annexées.The invention aims to provide a watch which does not suffer from the drawbacks described above. This object is achieved by the watch according to the appended claims.

Une montre selon l'invention comprend un organe de commande qui commande en une ou plusieurs fonctionnalités électroniques. L'organe de commande est monté de manière élastique sur un élément allongé, de sorte que l'utilisateur puisse faire balancer l'organe selon au moins une direction et de préférence selon deux dimensions par rapport à l'élément allongé. Au moins un détecteur de proximité est incorporé dans la carrure de la montre, à un endroit qui permet à ce détecteur de produire un signal qui est représentatif du balancement de l'organe autour d'un axe qui est perpendiculaire à l'axe central de l'élément allongé. Un processeur génère au moins une commande sur la base de signaux fournit par le détecteur de proximité ou les détecteurs de proximité, par exemple pour permettre à l'utilisateur de naviguer dans un menu ou un calendrier affichés sur un écran digital de la montre.A watch according to the invention comprises a control member which controls one or more electronic functions. The control member is resiliently mounted on an elongate member, so that the user can swing the member in at least one direction and preferably in two dimensions relative to the elongated member. At least one proximity detector is incorporated in the middle part of the watch, at a location which allows this detector to produce a signal which is representative of the sway of the organ around an axis which is perpendicular to the central axis of the watch. the elongated element. A processor generates at least one command on the basis of signals supplied by the proximity detector or the proximity detectors, for example to allow the user to navigate in a menu or a calendar displayed on a digital screen of the watch.

Description détaillée d'une forme d'exécution de l'inventionDetailed description of an embodiment of the invention

L'invention s'applique aussi bien à des montres munies d'un mouvement mécanique que d'un mouvement électromécanique. Il peut même s'appliquer à une montre électronique sans aiguilles.The invention applies equally to watches provided with a mechanical movement and an electromechanical movement. It can even apply to an electronic watch without hands.

Dans le cas d'un mouvement mécanique, la montre est pourvue de fonctions additionnelles avec un caractère électronique. Cette montre peut comporter un écran digital qui s'étend sur une portion du cadran, prévu pour l'affichage du temps par des aiguilles, et sur lequel s'affichent diverses données, telles que la date, le temps, des messages alphanumériques ou d'autres informations qui sont accessibles par exemple en navigant dans un ou plusieurs menus. La montre comprend un mécanisme tige-couronne de remontage et de réglage des aiguilles, bien connu dans l'état de la technique. Selon cette forme d'exécution de l'invention, la couronne sert également de moyen de commande de fonctions électroniques, grâce à un ensemble de capteurs formant des détecteurs de proximité qui servent à détecter un basculement de la couronne selon deux dimensions orthogonales à la direction axiale de la tige.In the case of a mechanical movement, the watch is provided with additional functions with an electronic character. This watch may include a digital screen which extends over a portion of the dial, provided for the display of time by hands, and on which various data are displayed, such as the date, the time, alphanumeric or digital messages. other information which is accessible for example by navigating in one or more menus. The watch comprises a stem-crown mechanism for winding and adjusting the hands, well known in the state of the art. According to this embodiment of the invention, the crown also serves as a means of controlling electronic functions, thanks to a set of sensors forming proximity detectors which serve to detect a tilting of the crown in two dimensions orthogonal to the axial direction of the rod.

Les figures 1 et 2 représentent des coupes verticale et horizontale du mécanisme tige-couronne dans une montre selon une forme d'exécution de l'invention. De manière connue, la couronne 1 est reliée à une tige de remontoir 2 par l'intermédiaire d'un raccord-tige 6 chassé sur une extrémité de la tige 2. L'ensemble de la tige 2 et du raccord-tige 6 passe à travers un tube 3 monté de manière fixe dans un trou 4 pourvu dans la paroi de la carrure 5 de la montre. Dans la montre terminée, la carrure 5 forme le support dans lequel est installé un mouvement horloger qui est réglable par le mécanisme tige-couronne. Des joints toriques 9 sont insérés entre le tube 3 et la carrure 5 et entre le tube et le raccord-tige 6 pour assurer l'étanchéité du mécanisme. La couronne est montée d'un côté du raccord-tige 6, de sorte que la rotation de la couronne autour de son axe central 10 entraine le raccord-tige 6 et la tige 2 en rotation, autour de leur axe central 10' qui est coaxial avec l'axe central 10. Le raccord-tige 6 est logé dans le tube 3 de manière rotative, et avec une tolérance réduite, de sorte que le raccord-tige 6 est essentiellement immobile en direction radiale.The figures 1 and 2 represent vertical and horizontal sections of the stem-crown mechanism in a watch according to one embodiment of the invention. In a known manner, the crown 1 is connected to a winding stem 2 by means of a stem connector 6 driven onto one end of the stem 2. The assembly of the stem 2 and of the stem connector 6 passes to through a tube 3 fixedly mounted in a hole 4 provided in the wall of the caseband 5 of the watch. In the finished watch, the middle 5 forms the support in which is installed a watch movement which is adjustable by the stem-crown mechanism. O-rings 9 are inserted between the tube 3 and the middle 5 and between the tube and the rod connector 6 to seal the mechanism. The crown is mounted on one side of the rod connector 6, so that the rotation of the crown around its central axis 10 causes the rod connector 6 and the rod 2 to rotate, around their central axis 10 'which is coaxial with the central axis 10. The rod connector 6 is housed in the tube 3 in a rotatable manner, and with a reduced tolerance, so that the rod connector 6 is essentially stationary in the radial direction.

L'ensemble du raccord-tige 6 et de la tige 2 représente une forme d'exécution d'un élément allongé auquel la couronne est fixée. On notera que cet ensemble peut prendre différentes formes selon le type de montre. En particulier, le raccord-tige et la tige peuvent former un seul et même élément. Dans le cas d'une montre purement digitale, on peut prévoir une couronne rotative fixée sur un élément allongé formant une tige électronique. De manière générale, l'élément allongé est un élément qui définit un axe central 10' et qui fait saillie hors de la carrure 5 de la montre, l'extrémité extérieure de cet élément allongé formant une rotule pour la couronne, comme ceci sera exposé plus en détails par la suite.The assembly of the rod connector 6 and of the rod 2 represents an embodiment of an elongated element to which the crown is fixed. It will be noted that this assembly can take different forms depending on the type of watch. In particular, the rod connector and the rod can form one and the same element. In the case of a purely digital watch, it is possible to provide a rotating crown fixed to an elongated element forming an electronic rod. In general, the elongated element is an element which defines a central axis 10 'and which projects out of the middle part 5 of the watch, the outer end of this elongated element forming a ball joint for the crown, as will be explained. in more detail later.

De plus, la couronne 1 n'est qu'une forme d'exécution d'un organe de commande monté latéralement par rapport à la carrure et auquel l'invention est applicable. Un autre exemple d'un tel organe de commande est la tête (généralement non-rotative) d'un poussoir équipant un chronographe. L'invention sera décrite pour le cas de la couronne rotative, qui représente le cas le plus courant dans le domaine horloger mais qui ne limite pas la portée de l'invention.In addition, the crown 1 is only one embodiment of a control member mounted laterally with respect to the middle part and to which the invention is applicable. Another example of such a control member is the head (generally non-rotating) of a pusher fitted to a chronograph. The invention will be described for the case of the rotating crown, which represents the most common case in the watchmaking field but which does not limit the scope of the invention.

Il est à noter que l'invention ne se limite pas à des organes de commande qui ont une fonction désignée et liée à la rotation ou le mouvement axial de l'organe de commande. L'invention couvre également un organe de commande qui n'est pas rotatif autour de l'axe de l'élément allongé ni déplaçable en direction axiale. Dans ce cas particulier, l'organe de commande est premièrement dédié à la fonction 'joystick' selon l'invention.It should be noted that the invention is not limited to control members which have a designated function linked to the rotation or the axial movement of the control member. The invention also covers a control member which is neither rotatable about the axis of the elongated member nor movable in the axial direction. In this particular case, the control member is firstly dedicated to the “joystick” function according to the invention.

Dans les figures, la couronne 1 est représentée dans une position relativement proche de la carrure 5, par exemple à une distance 'q' (marquée à la figure 1) inférieure à 1 mm. Cette position est appelée position de repos'. De manière connue en soi, cette position permet par exemple à l'utilisateur d'une montre mécanique de remonter sa montre manuellement en tournant la couronne 1. Selon des formes d'exécution, et de manière également connue, la couronne 1 peut être éloignée de la carrure 5, en tirant manuellement cette couronne et entraînant la tige 2 en direction axiale, pour activer des modes de réglage mécanique tel que l'ajustement de la position des aiguilles et, le cas échéant, la date. Différents systèmes existent qui règlent le positionnement axial de la couronne 1 et l'actionnement du réglage mécanique, et l'invention est applicable en combinaison avec l'un quelconque de ces systèmes. Indépendamment du système appliqué, l'invention est relative à des fonctionnalités apportées à la couronne 1 quand celle-ci se trouve de préférence dans la position de repos.In the figures, the crown 1 is shown in a position relatively close to the caseband 5, for example at a distance 'q' (marked at the figure 1 ) less than 1 mm. This position is called the rest position '. In a manner known per se, this position allows for example the user of a mechanical watch to wind his watch manually by turning the crown 1. According to embodiments, and in a manner also known, the crown 1 can be moved away. of the middle part 5, by manually pulling this crown and driving the rod 2 in the axial direction, to activate mechanical adjustment modes such as adjusting the position of the hands and, where appropriate, the date. Different systems exist which regulate the axial positioning of the crown 1 and the actuation of the mechanical adjustment, and the invention is applicable in combination with any of these systems. Regardless of the system applied, the invention relates to functions provided to the crown 1 when the latter is preferably in the rest position.

Comme illustré aux figures 1 et 2, la couronne 1 est montée sur le raccord-tige 6 via un bloc cylindrique 15 en matériau élastique, formant une rotule, qui permet de faire balancer la couronne 1, de manière auto-réversible, autour des axes Y et Z d'un système d'axes orthogonaux XYZ, dont l'axe X est colinéaire avec l'axe central 10' de la tige 2 et de l'axe central 10 de la couronne. Plus particulièrement, l'axe Z est essentiellement perpendiculaire au plan général de la carrure 5, et Y est dans ce plan général. Le balancement de la couronne autour des axes Y et Z est actionnable par l'utilisateur, par la manipulation manuelle de la couronne 1 par rapport à la carrure 5. L'utilisateur peut faire balancer la couronne autour de Y ou Z séparément ou simultanément (le dernier étant le cas pour la plupart des manipulations selon deux dimensions). Le caractère auto-réversible du balancement signifie que la couronne revient à sa position de repos dès que l'utilisateur relâche la couronne 1. Le matériau de la rotule 15 est sélectionné tel que ce balancement auto-réversible soit réalisable. Un matériau élastique ou élastomère d'une flexibilité adéquate est utilisable à ce but.As shown in figures 1 and 2 , the crown 1 is mounted on the rod connector 6 via a cylindrical block 15 of elastic material, forming a ball joint, which allows the crown 1 to swing, in a self-reversible manner, around the Y and Z axes of a system of orthogonal axes XYZ, the X axis of which is collinear with the central axis 10 'of the rod 2 and the central axis 10 of the crown. More particularly, the Z axis is essentially perpendicular to the general plane of the middle part 5, and Y is in this general plane. The crown swinging around the Y and Z axes can be actuated by the user, by manually manipulating the crown 1 with respect to the middle 5. The user can swing the crown around Y or Z separately or simultaneously ( the last being the case for most manipulations in two dimensions). The self-reversible nature of the swing means that the crown returns to its rest position as soon as the user releases the crown 1. The material of the ball joint 15 is selected such that this self-reversible swing is achievable. An elastic or elastomeric material of adequate flexibility can be used for this purpose.

Selon l'invention et en référence aux figures 3 à 6, deux détecteurs de proximité 16 et 17 sont intégrés dans la carrure 5, de sorte que ces détecteurs permettent de mesurer les variations de la distance entre la carrure 5 et la couronne 1, en fonction des rotations respectives de la couronne autour des axes Y et Z. Selon la forme d'exécution spécifique représentée aux figures, les détecteurs 16 et 17 sont intégrés dans le tube 3, et le tube 3 est incorporé dans la paroi de la carrure.According to the invention and with reference to figures 3 to 6 , two proximity detectors 16 and 17 are integrated in the caseband 5, so that these detectors make it possible to measure the variations in the distance between the caseband 5 and the crown 1, as a function of the respective rotations of the crown around the axes Y and Z. According to the specific embodiment shown in the figures, the detectors 16 and 17 are integrated in the tube 3, and the tube 3 is incorporated in the wall of the caseband.

De préférence, les détecteurs 16 et 17 sont positionnés de façon orthogonale l'un par rapport à l'autre. Une déviation de ce positionnement orthogonal est permise, à condition que les balancements autour de Y et Z puissent être dérivés des signaux mesurés, tenant compte de la position angulaire des détecteurs dans le plan YZ. Tout type de détecteur de proximité peut être utilisé. De préférence, et comme c'est le cas dans la forme d'exécution illustrée aux figures, des détecteurs magnétiques à réluctance variable sont implémentés. Dans les figures 3 à 6, on voit comment les détecteurs 16 et 17 sont intégrés dans le tube 3. Chacun des détecteurs comprend une tige en forme de 'U'. Cette tige est fabriquée d'un matériau ferromagnétique, tel que la ferrite. La tige comprend deux jambes 20 et une portion de raccord 21 entre les jambes 20. Les deux jambes 20 sont insérées dans des trous borgnes respectifs 22 pourvus dans la paroi du tube 3, selon une direction axiale de ce tube, de sorte que les extrémités des jambes 20 soient positionnées à proximité de la surface latérale extérieure 23 du tube 3, cette surface 23 se trouvant en face de la partie arrière de la couronne. Les trous 22 pourraient également traverser le tube 3 d'un côté à l'autre. La portion de raccord 21 est pourvue d'un solénoïde 24 qui est connecté à une carte de circuit imprimé (PCB) 25 attachée à la surface latérale intérieur du tube 3, et sur lequel se trouvent des moyens (non-représentés) pour mesurer un courant passant par le solénoïde 24. Comme montré aux figures, les détecteurs 16 et 17 sont positionnés à côté du mécanisme tige-couronne, mais à une distance telle que les extrémités des jambes 20 se trouvent en face de la surface intérieure de la couronne 1. Un anneau 26 en matériau ferromagnétique (par exemple ferrite) est incorporé dans la partie arrière de la couronne 1, de sorte que la surface latérale de cet anneau 26 se trouve en face des extrémités des jambes 20 des deux détecteurs quelle que soit la position angulaire de la couronne. Chacune des tiges en forme de U forme une partie d'un circuit magnétique à réluctance variable, la réluctance étant variable en fonction de la position axiale de l'anneau 26 de la couronne 1. Un changement de la distance entre l'anneau 26 et les détecteurs, obtenu par un basculement de la couronne grâce à la rotule élastique, va changer la réluctance d'au moins un des deux circuits magnétiques, ce qui sera détecté sur base d'un changement du courant circulant dans au moins un des solénoïdes 24 lorsqu'une une tension donnée est appliquée à chacun de ces solénoïdes (aussi nommées bobines).Preferably, the detectors 16 and 17 are positioned orthogonally to each other. A deviation from this orthogonal positioning is allowed, provided that the swings around Y and Z can be derived from the measured signals, taking into account the angular position of the detectors in the YZ plane. Any type of proximity switch can be used. Preferably, and as is the case in the embodiment illustrated in the figures, variable reluctance magnetic detectors are implemented. In the figures 3 to 6 , we see how the detectors 16 and 17 are integrated in the tube 3. Each of the detectors comprises a rod in the form of 'U'. This rod is made of a ferromagnetic material, such as ferrite. The rod comprises two legs 20 and a connecting portion 21 between the legs 20. The two legs 20 are inserted in respective blind holes 22 provided in the wall of the tube 3, in an axial direction of this tube, so that the ends of the legs 20 are positioned close to the outer side surface 23 of the tube 3, this surface 23 being in face of the rear part of the crown. The holes 22 could also pass through the tube 3 from side to side. The connector portion 21 is provided with a solenoid 24 which is connected to a printed circuit board (PCB) 25 attached to the inner side surface of the tube 3, and on which there are means (not shown) for measuring a current passing through the solenoid 24. As shown in the figures, the detectors 16 and 17 are positioned next to the stem-crown mechanism, but at a distance such that the ends of the legs 20 are in front of the inner surface of the crown 1 A ring 26 of ferromagnetic material (for example ferrite) is incorporated in the rear part of the ring 1, so that the lateral surface of this ring 26 is located opposite the ends of the legs 20 of the two detectors whatever the position. angular crown. Each of the U-shaped rods forms part of a variable reluctance magnetic circuit, the reluctance being variable depending on the axial position of the ring 26 of the crown 1. A change in the distance between the ring 26 and the detectors, obtained by tilting the crown thanks to the elastic ball joint, will change the reluctance of at least one of the two magnetic circuits, which will be detected on the basis of a change in the current flowing in at least one of the solenoids 24 when a given voltage is applied to each of these solenoids (also called coils).

La rotation de la couronne 1 autour des axes Y et Z, actionné par l'utilisateur, varie donc les distances respectives entre l'anneau 26 et les deux détecteurs 16 et 17, de sorte que les signaux générés par ces détecteurs sont représentatifs de ces distances et donc de l'ampleur dudit balancement autour des deux axes orthogonaux Y et Z définissant les deux dimensions du balancement. On remarquera qu'un balancement autour de l'axe Y correspond à un balancement selon l'axe Z, et réciproquement. Ces signaux peuvent donc être interprétés comme des commandes pour gérer des fonctions électroniques de la montre, tel que la navigation dans un menu affiché sur un écran digital de la montre. La couronne 1 remplit alors une fonction comparable à celle d'un joystick d'une console de commande pour un ordinateur.The rotation of the ring 1 around the Y and Z axes, actuated by the user, therefore varies the respective distances between the ring 26 and the two detectors 16 and 17, so that the signals generated by these detectors are representative of these distances and therefore the magnitude of said swing around the two orthogonal axes Y and Z defining the two dimensions of the swing. It will be noted that a swing around the Y axis corresponds to a swing along the Z axis, and vice versa. These signals can therefore be interpreted as commands to manage electronic functions of the watch, such as navigation in a menu displayed on a digital screen of the watch. The crown 1 then fulfills a function comparable to that of a joystick of a control console for a computer.

Un processeur (non-représenté) est à bord du PCB 25 pour traiter les signaux générés par les deux détecteurs de proximité et pour les traduire en commandes qui vont gérer une ou plusieurs fonctionnalités électroniques de la montre, par exemple le pilotage d'un curseur sur l'écran digital de la montre. On peut implémenter des méthodes et des algorithmes bien connus du domaine de l'informatique, pour le traitement des signaux ainsi que pour la génération de commandes. Une batterie ou autre source d'énergie électrique, tel qu'une cellule photovoltaïque, est présente dans la montre pour alimenter les composants montés sur le PCB 25 et/ou d'autres composants électroniques implémentés dans la montre.A processor (not shown) is on board the PCB 25 to process the signals generated by the two proximity detectors and to translate them into commands which will manage one or more electronic functions of the watch, for example the piloting of a cursor. on the digital screen of the watch. It is possible to implement methods and algorithms well known in the field of computer science, for the processing of signals as well as for the generation of commands. A battery or other source of electrical energy, such as a photovoltaic cell, is present in the watch to power the components mounted on the PCB 25 and / or other electronic components implemented in the watch.

L'invention n'est pas limitée à des formes d'exécution pourvue de deux détecteurs de proximité. Une montre selon l'invention pourrait comprendre un seul détecteur agencé de manière à pouvoir mesurer une manipulation selon une seule direction, par exemple seulement le détecteur 16. Il est également envisageable de prévoir plus que deux détecteurs, par exemple quatre situés à quatre endroits autour de l'axe de la couronne, correspondant notamment aux angles 0, 90°, 180° et 270°.The invention is not limited to embodiments provided with two proximity detectors. A watch according to the invention could comprise a single detector arranged so as to be able to measure a manipulation in a single direction, for example only the detector 16. It is also possible to envisage providing more than two detectors, for example four located at four locations around it. of the axis of the crown, corresponding in particular to angles 0, 90 °, 180 ° and 270 °.

Parmi les formes d'exécution pourvues d'au moins deux détecteurs de proximité, des formes d'exécution particulières sont par exemple l'attribution de fonctionnalités spécifiques en fonction de la direction dans laquelle l'organe de commande est manipulé dans un plan perpendiculaire à l'axe central 10'. Par exemple, dans le cas de la forme d'exécution représentée aux figures, le balancement autour de l'axe Y, détectée seulement par le détecteur 17, pourra commander une fonction différente que le balancement autour de l'axe Z, détectée seulement par le détecteur 16. Dans ce cas, le processeur est préférentiellement configuré de sorte qu'une légère déviation de l'axe de rotation du balancement par rapport aux axes Y et Z sera négligée.Among the embodiments provided with at least two proximity detectors, particular embodiments are for example the allocation of specific functionalities according to the direction in which the control member is manipulated in a plane perpendicular to the central axis 10 '. For example, in the case of the embodiment shown in the figures, the sway around the Y axis, detected only by the detector 17, can control a different function than the sway around the Z axis, detected only by detector 16. In this case, the processor is preferably configured so that a slight deviation of the axis of rotation of the swing relative to the Y and Z axes will be neglected.

Selon d'autres formes d'exécution, la couronne 1 (ou tout autre organe de commande auquel l'invention est applicable) est capable de subir un déplacement axial auto-réversible à partir de la position de repos, à la manière d'un poussoir de chronographe. Ce déplacement axial est actionné par l'utilisateur qui pousse la couronne brièvement vers la carrure 5 et puis relâche la couronne, qui revient de manière automatique vers sa position initiale. Ceci est réalisable par exemple quand la couronne 1 est assemblée à la tige 2 via un mécanisme de poussoir à ressort, connu en soi. Selon les formes d'exécution pertinentes pour l'invention, la montre est munie d'un détecteur agencé pour détecter ce déplacement axial de sorte que le processeur génère en réponse une commande spécifique et différente des commandes générées par le balancement de la couronne. Les commandes générées par la poussée de la couronne peuvent être des commandes de confirmation d'une sélection parmi des options présentées par exemple dans un menu. La poussée réversible peut aussi être utilisée également pour activer ou désactiver la fonction de 'joystick' de la couronne. La durée de la poussée peut déterminer la commande. Par exemple, une durée plus longue pour l'activation ou désactivation de la fonction 'joystick' et une durée plus courte pour confirmer une sélection dès que la fonction est active.According to other embodiments, the crown 1 (or any other control member to which the invention is applicable) is capable of undergoing a self-reversible axial displacement from the rest position, in the manner of a chronograph pusher. This axial movement is actuated by the user who pushes the crown briefly towards the middle part 5 and then releases the crown, which automatically returns to its initial position. This is achievable for example when the crown 1 is assembled to the rod 2 via a spring push mechanism, known per se. According to the embodiments relevant to the invention, the watch is provided with a detector designed to detect this axial displacement so that the processor generates in response a specific command and different from the commands generated by the swinging of the crown. The commands generated by pushing the crown can be commands for confirming a selection from among the options presented for example in a menu. The reversible push can also be used also to activate or deactivate the 'joystick' function of the crown. The duration of the push may determine the command. For example, a longer duration for activating or deactivating the 'joystick' function and a shorter duration for confirming a selection as soon as the function is active.

Selon une forme d'exécution préférée, les détecteurs 16 et 17 eux-mêmes sont utilisés pour détecter la poussée réversible de la couronne vers la carrure. Ceci est réalisable en configurant le processeur de manière qu'un déplacement axial de la couronne, engendrant un rapprochement de cette couronne et donc de l'anneau ferromagnétique 26 des deux détecteurs qui est donc détecté simultanément par les deux détecteurs de proximité, soit interprété comme une poussée réversible de la couronne. En effet, contrairement au cas d'un balancement, un déplacement axial de la couronne engendre une même variation de distance (une même diminution de la distance 'q') pour les deux détecteurs qui sont agencés pour détecter cette variation de distance. De manière alternative, un détecteur additionnel peut être implémenté, qui est spécifiquement configuré pour détecter le déplacement axial de la couronne en direction de la carrure. Par exemple, une paire de contacts galvaniques pourraient être prévus, qui se touchent quand la couronne est poussée, ou plus avantageusement un détecteur capacitif pourrait être implémenté.According to a preferred embodiment, the detectors 16 and 17 themselves are used to detect the reversible thrust of the crown towards the middle. This can be done by configuring the processor in such a way that an axial displacement of the ring, causing this ring to come together and therefore of the ferromagnetic ring 26 of the two detectors which is therefore detected simultaneously by the two proximity detectors, is interpreted as a reversible thrust of the crown. In fact, unlike in the case of a swing, an axial displacement of the crown generates the same variation in distance (the same reduction in the distance 'q') for the two detectors which are arranged to detect this variation in distance. Alternatively, an additional detector can be implemented, which is specifically configured to detect the axial displacement of the crown towards the middle. For example, a pair of galvanic contacts could be provided, which touch each other when the crown is pushed, or more advantageously a capacitive detector could be implemented.
