Description détaillée des modes de réalisation préférés Detailed Description of the Preferred Embodiments
L'invention concerne une boîte 1 de montre, comportant un logement 2 dans lequel est mobile, au moins en rotation, au moins une molette 3 de commande d'un affichage ou d'une fonction de la montre. Cette molette 3 est agencée pour être manipulée directement par l'utilisateur de la montre au niveau d'une surface périphérique de contact 4. La dénomination de « boîte » est à prendre au sens large : cette boîte 1 peut naturellement être une carrure ou similaire.  The invention relates to a watch case 1, comprising a housing 2 in which is movable, at least in rotation, at least one control wheel 3 of a display or a function of the watch. This wheel 3 is arranged to be handled directly by the user of the watch at a peripheral contact surface 4. The denomination "box" is to be taken in the broad sense: this box 1 can naturally be a middle or the like .
Les figures 1 et 2 montrent une telle boîte 1 , dans laquelle le logement 2 est une rainure en forme de gorge, avec, de part et d'autre d'un fond 20, une cloison intérieure 21 et une cloison extérieure 22. Cette cloison extérieure 22 est interrompue entre deux bords 23 et 24, agencés pour définir une ouverture par laquelle un utilisateur peut manœuvrer une molette 3 insérée dans le logement 2, tel que visible sur la figure 5.  Figures 1 and 2 show such a box 1, wherein the housing 2 is a groove-shaped groove, with, on either side of a bottom 20, an inner partition 21 and an outer wall 22. This partition 22 is interrupted between two edges 23 and 24, arranged to define an opening by which a user can operate a knob 3 inserted into the housing 2, as shown in Figure 5.
La géométrie du logement 2 permet l'insertion, avec du jeu, d'une telle molette 3, et permet en particulier que la molette 3puisse tourner et translater sur une distance faible, par exemple et non limitativement dans la direction 3h-9h sur la boîte 1 illustrée par les figures, et avec une ouverture afin que l'utilisateur de la montre puisse effectuer deux mouvements: pousser radialement la molette 3, et la faire tourner.  The geometry of the housing 2 allows the insertion, with play, of such a knob 3, and allows in particular that the wheel 3 can rotate and translate a small distance, for example and not limited to the direction 3h-9h on the box 1 illustrated by the figures, and with an opening so that the user of the watch can perform two movements: push the wheel 3 radially, and rotate it.
Selon l'invention, ce logement 2 est agencé pour autoriser un mouvement limité de translation, entre une fin de course intérieure et une fin de course extérieure, d'au moins une partie 30 de la molette 3 selon une direction radiale de la boîte 1 , à rencontre de moyens de rappel élastique 5 qui sont agencés pour éloigner la partie 30 de l'intérieur de la boîte 1 . On comprend que la partie 30 n'est pas toujours la même: il s'agit seulement de la partie de la molette 3, qui fait face à un instant donné à l'ouverture, définie sur les figures par les deux bords 23 et 24.  According to the invention, this housing 2 is arranged to allow a limited movement of translation, between an inner end-stop and an outer end-of-travel, of at least one part 30 of the wheel 3 in a radial direction of the box 1 , opposite elastic return means 5 which are arranged to move the part 30 away from the inside of the box 1. It is understood that the part 30 is not always the same: it is only the part of the wheel 3, which faces at a given instant at the opening, defined in the figures by the two edges 23 and 24 .
Les figures illustrent une variante particulière, où le logement 2 de la molette 3 est à proximité immédiate de la périphérie de la boîte 1 . Ainsi la molette 3 entoure un mouvement 100, sans contact direct avec celui-ci.  The figures illustrate a particular variant, where the housing 2 of the wheel 3 is in the immediate vicinity of the periphery of the box 1. Thus the wheel 3 surrounds a movement 100, without direct contact with it.
D'autres variantes sont réalisables, en particulier avec une petite molette, qui ne fait pas le tour de la montre, mais qui est sensiblement tangente intérieurement à sa périphérie, seule une partie 30 de la molette 3 étant, comme précédemment, accessible à l'utilisateur. Le logement 2 de cette petite molette est aussi séparé, de façon étanche, du compartiment intérieur de la boîte 1 qui enferme le mouvement 100. Other variants are feasible, in particular with a small wheel, which does not circumnavigate the watch, but which is substantially tangent internally to its periphery, only a part 30 of the wheel 3 being, as before, accessible to the user. The housing 2 of this small wheel is also separated, in a sealed manner, the inner compartment of the box 1 which encloses the movement 100.
Les moyens de rappel élastique 5 assurent la fonction de répulsion de la molette 3 vers l'extérieur de la boîte 1 au repos, au niveau de l'ouverture.  The elastic return means 5 provide the repulsion function of the wheel 3 towards the outside of the box 1 at rest, at the opening.
Pour assurer la fonction de détection d'appui lors de l'enfoncement de la molette 3, à proximité du logement 2, la boîte 1 comporte encore au moins un premier moyen de détection de commande 7, qui est agencé pour détecter la présence de la partie 30 de la molette 3 au plus près du centre de la boîte 1 lors d'un appui imposé par un utilisateur, et notamment en fin de course intérieure.  To ensure the support detection function when the wheel 3 is depressed near the housing 2, the box 1 also comprises at least a first control detection means 7, which is arranged to detect the presence of the part 30 of the wheel 3 closer to the center of the box 1 during a user-imposed support, including the end of internal race.
De façon particulière et non limitative, et tel que visible sur les figures 1 à 4, la boîte 1 peut être munie d'un poussoir 54 constituant ces moyens de rappel élastique 5, qui vient contraindre la molette 3 dans une position extrême dans la direction où elle peut translater, dans la position 3h dans le cas particulier des figures. Plus particulièrement, ce poussoir 54 comporte une tête 53 en forme de patin pour faciliter la rotation de la molette 3. Du côté intérieur de la boîte 1 , ce poussoir 54, qui traverse ici la cloison intérieure 21 , comporte une queue agencée pour coopérer avec un premier moyen de détection de commande 7. Du fait de ses petites dimensions, un tel poussoir 54 ne pose guère de problème d'étanchéité. Pour un environnement plus exigeant, tel que montre de plongée ou similaire, il peut être avantageux de dissocier, d'une part la fonction de répulsion de la molette 3 vers l'extérieur de la boîte 1 au repos, au niveau de l'ouverture, par exemple par un ressort-lame ou similaire, et d'autre part la fonction de détection d'appui lors de l'enfoncement de la molette 3, par une jauge de contrainte dans la cloison intérieure 21 , un capteur inductif, l'utilisation d'une cloison déformable, ou autre.  In a particular and nonlimiting manner, and as visible in Figures 1 to 4, the box 1 may be provided with a pusher 54 constituting these elastic return means 5, which constrains the wheel 3 in an extreme position in the direction where it can translate, in the 3h position in the particular case of the figures. More particularly, this pusher 54 comprises a head 53 in the form of a pad to facilitate the rotation of the wheel 3. On the inside of the box 1, this pusher 54, which passes through the inner partition 21, has a tail arranged to cooperate with a first control detection means 7. Because of its small dimensions, such a pusher 54 poses little problem of sealing. For a more demanding environment, such as a diving watch or the like, it may be advantageous to dissociate, on the one hand, the repulsion function of the wheel 3 towards the outside of the box 1 at rest, at the level of the opening , for example by a leaf spring or the like, and on the other hand the function of detecting the support during the driving of the wheel 3, by a strain gauge in the internal partition 21, an inductive sensor, the use of a deformable partition, or other.
La figure 3 montre le système au repos, le poussoir 54 maintient la molette 3 vers la position à 3h.  Figure 3 shows the system at rest, the pusher 54 keeps the wheel 3 to the position at 3 o'clock.
La figure 4 montre le système lors d'un appui sur la molette 3 par un utilisateur: sa zone locale 30 translate depuis a position à 3h vers la position à 9h, le poussoir 54 est repoussé vers l'intérieur de la boîte 1 . Par exemple on détecte cette pression par un module électronique dans le mouvement 100 de la montre 200.  FIG. 4 shows the system during a pressing on the wheel 3 by a user: his local area 30 translates from a position at 3 o'clock to the 9 o'clock position, the pusher 54 is pushed towards the inside of the box 1. For example, this pressure is detected by an electronic module in the movement 100 of the watch 200.
Ce premier moyen de détection 7 est agencé pour activer ou désactiver des moyens capteurs 8 que comporte la boîte 1 à proximité du logement 2, lesquels moyens capteurs 8 sont agencés pour détecter, lors d'un mouvement de rotation imprimé par l'utilisateur à la molette 3, le passage de moyens émetteurs 9 que comporte la molette 3. This first detection means 7 is arranged to activate or deactivate sensor means 8 that includes the box 1 near the housing 2, which sensor means 8 are arranged to detect, during a rotational movement printed by the user at the wheel 3, the passage of emitter means 9 that comprises the wheel 3.
Plus particulièrement, les moyens émetteurs 9 sont discontinus, et agencés selon des pas angulaires différents autour de la molette 3.  More particularly, the emitter means 9 are discontinuous, and arranged in different angular increments around the wheel 3.
Plus particulièrement, les moyens capteurs 8 sont maintenus distants des moyens émetteurs 9, il s'agit alors d'une interaction sans contact.  More particularly, the sensor means 8 are kept remote from the emitter means 9, it is then a contactless interaction.
Dans une variante particulière, au moins un des moyens capteurs 8 est agencé pour détecter le sens de passage ou/et l'inversion de sens de passage d'un moyen émetteur 9.  In a particular variant, at least one of the sensor means 8 is arranged to detect the direction of passage or / and the reversal of the direction of passage of an emitter means 9.
Dans une variante particulière, au moins un des moyens capteurs 8 est agencé pour détecter l'écart angulaire entre deux moyens émetteurs 9 successifs.  In a particular variant, at least one of the sensor means 8 is arranged to detect the angular difference between two successive emitter means 9.
Dans une variante particulière, au moins deux des moyens capteurs 8 sont agencés pour détecter le passage d'un même moyen émetteur 9.  In a particular variant, at least two of the sensor means 8 are arranged to detect the passage of the same transmitter means 9.
Dans une variante particulière, au moins un des moyens capteurs 8 est agencé pour mesurer l'angle de rotation de la molette 3, parcouru depuis une détection de commande effectuée par le premier moyen de détection 7.  In a particular variant, at least one of the sensor means 8 is arranged to measure the rotation angle of the wheel 3, traveled since a control detection performed by the first detection means 7.
Dans une variante particulière, au moins un des moyens capteurs 8 est agencé pour changer de position lors du passage d'un moyen émetteur 9 à sa proximité. Plus particulièrement, un tel moyen capteur 8 constitue une bascule mécanique, agencée pour commander une fonction mécanique ou électronique d'un mouvement d'horlogerie 100 que renferme la boîte 1 . Le mécanisme selon l'invention peut, ainsi, dans une variante particulière, être complètement mécanique. La combinaison des composants mobiles de déclenchement et d'arrêt de fonction peut aussi être séquentielle. Par exemple, un mouvement quelconque de mise en rotation de la molette peut déclencher successivement, sur un mécanisme de chronographe, la mise en marche, l'arrêt, et la remise à zéro.  In a particular variant, at least one of the sensor means 8 is arranged to change position during the passage of a transmitter means 9 to its vicinity. More particularly, such a sensor means 8 constitutes a mechanical rocker, arranged to control a mechanical or electronic function of a clockwork movement 100 contained in the box 1. The mechanism according to the invention can thus, in a particular variant, be completely mechanical. The combination of the mobile trip and stop components can also be sequential. For example, any movement of rotation of the wheel can trigger successively, on a chronograph mechanism, the start, stop, and reset.
Dans une variante avantageuse, la boîte 1 comporte des moyens de pilotage 10, qui sont agencés pour gérer les signaux émis et reçus au niveau du premier moyen de détection 7 et des moyens capteurs 8, pour activer ou désactiver ces moyens capteurs 8, et pour, quand les moyens capteurs 8 sont activés, analyser le nombre des moyens émetteurs 9 identifiés par les moyens capteurs 8, et/ou l'écart angulaire des moyens émetteurs 9 deux à deux, et/ou les sens de passage des moyens émetteurs 9, pour transformer le résultat de l'analyse en un ordre d'affichage ou d'activation d'une fonction de la montre, adressé à un mouvement d'horlogerie 100 que renferme la boîte 1 . Plus particulièrement, le moyen de détection 7, et/ou les moyens capteurs 8, et/ou les moyens de pilotage 10, sont de type électronique. In an advantageous variant, the box 1 comprises control means 10, which are arranged to manage the signals transmitted and received at the first detection means 7 and the sensor means 8, to activate or deactivate these sensor means 8, and for when the sensor means 8 are activated, analyzing the number of emitter means 9 identified by the sensor means 8, and / or the angular deviation of the emitter means 9 two by two, and / or the direction of passage of the emitter means 9, to turn the result of the analysis into an order display or activation of a function of the watch, addressed to a watch movement 100 contained in the box 1. More particularly, the detection means 7, and / or the sensor means 8, and / or the control means 10 are of the electronic type.
Dans une variante particulière, la molette 3 est flexible et constitue elle-même les moyens de rappel élastique 5. Dans cette variante le logement 2 peut consister en une gorge de révolution, parfaitement annulaire, et le poussoir 54, agencé pour la détection de la pression d'appui, joue avantageusement le rôle supplémentaire d'un tendeur de cette molette 3 flexible, et donne localement la forme circulaire à cette molette 3 flexible.  In a particular variant, the wheel 3 is flexible and constitutes itself the elastic return means 5. In this variant the housing 2 may consist of a groove of revolution, perfectly annular, and the pusher 54, arranged for the detection of the bearing pressure, advantageously plays the additional role of a tensioner of this flexible wheel 3, and locally gives the circular shape to this flexible wheel 3.
Dans une autre variante particulière, illustrée par les figures, la molette 3 est rigide, et les moyens de rappel élastique 5 comportent un poussoir 54, qui est agencé pour prendre appui sur la molette 3 par sa tête 53.  In another particular variant, illustrated by the figures, the wheel 3 is rigid, and the elastic return means 5 comprise a pusher 54, which is arranged to bear on the wheel 3 by its head 53.
Dans une variante particulière, illustrée par les figures, la molette 3 est annulaire, et le logement 2 est un ovale comportant deux demi-anneaux reliés par deux tronçons droits, tel que visible sur la figure 1 1 . Dans une variante chaque demi- anneau n'est pas strictement de révolution, mais le cercle le plus à l'extérieur, débouchant sur l'ouverture, comporte une excentricité, un peu supérieure à la valeur du décalage entre les deux cercles intérieurs, de façon à ce que la molette 3 dépasse d'un des côtés de la carrure mais pas de l'autre.  In a particular variant, illustrated by the figures, the wheel 3 is annular, and the housing 2 is an oval having two half-rings connected by two straight sections, as visible in Figure 1 1. In one variant each half-ring is not strictly of revolution, but the outermost circle, leading to the opening, comprises an eccentricity, a little greater than the value of the offset between the two inner circles, of so that the wheel 3 protrudes from one side of the middle but not from the other.
D'autres formes de logement sont envisageables, par exemple sensiblement elliptique, ou encore sensiblement annulaire, de largeur variable, et dont la projection sur toute parallèle à la direction radiale de la boîte 1 est au moins égale à l'écart entre la fin de course intérieure et la fin de course extérieure. De préférence, le logement 2 est de forme telle que le jeu soit le plus faible possible entre la molette 3 et les cloisons intérieure 21 et extérieure 22, sans pour autant provoquer de frottement excessif.  Other forms of housing are conceivable, for example substantially elliptical, or substantially annular, of variable width, and whose projection on any parallel to the radial direction of the box 1 is at least equal to the difference between the end of inner race and the outer race. Preferably, the housing 2 is shaped such that the game is as small as possible between the wheel 3 and the inner 21 and outer 22 walls, without causing excessive friction.
Dans une variante particulière, le premier moyen de détection 7 est un interrupteur actionné par les moyens de rappel élastique 5 ou par un poussoir 54 que comportent les moyens de rappel élastique 5.  In a particular variant, the first detection means 7 is a switch actuated by the elastic return means 5 or a pusher 54 that comprise the elastic return means 5.
Dans la variante illustrée par les figures, la molette 3 est munie d'aimants qui constituent les moyens émetteurs 9, notamment mais non limitativement disposés de manière régulière sur tout son pourtour, ce qui permet la détection de la rotation de la molette 3, via un ou plusieurs capteurs à l'intérieur la carrure qui constituent les moyens capteurs 8. In the variant illustrated by the figures, the wheel 3 is provided with magnets which constitute the emitter means 9, in particular but not exclusively, arranged in a regular manner all around its periphery, which allows the detection of the rotation. of the wheel 3, via one or more sensors inside the middle part which constitute the sensor means 8.
Ainsi, dans une variante particulière, les moyens capteurs 8 sont des capteurs magnétiques, qui sont agencés pour détecter, une fois activés, le passage d'aimants 91 que comportent les moyens émetteurs 9. Plus particulièrement, ces aimants 91 sont agencés selon un pas angulaire constant autour de la molette 3. Thus, in a particular variant, the sensor means 8 are magnetic sensors, which are arranged to detect, once activated, the passage of magnets 91 that comprise the emitter means 9. More particularly, these magnets 91 are arranged in a step constant angle around the wheel 3.
Dans une autre variante, ces aimants 91 sont agencés selon des pas angulaires différents autour de la molette 3. In another variant, these magnets 91 are arranged in different angular increments around the wheel 3.
Dans une variante particulière, la molette 3 comporte, sur une face agencée pour coopérer avec le fond 20 du logement 2, un relief 31 qui est agencé pour coopérer avec un relief complémentaire 21 que comporte le fond 20, pour un freinage par crantage lors de la rotation de la molette 3.  In a particular variant, the wheel 3 comprises, on a face arranged to cooperate with the bottom 20 of the housing 2, a relief 31 which is arranged to cooperate with a complementary relief 21 that comprises the bottom 20, for braking by notching during the rotation of the wheel 3.
Dans une variante particulière, la molette 3 comporte, sur une face agencée pour coopérer avec le fond 20 du logement 2, un relief 31 qui est agencé pour coopérer avec une bague 39 en relief interposée entre la molette 3 et le fond 20, pour un freinage par crantage lors de la rotation de la molette 3. Plus particulièrement, cette bague 39 en relief est une bague élastique. Plus particulièrement, cette bague 39 en relief comporte au moins une patte 38 d'arrêt radial, agencée pour coopérer de façon complémentaire avec un évidement 28 du logement 2.  In a particular embodiment, the wheel 3 comprises, on a face arranged to cooperate with the bottom 20 of the housing 2, a relief 31 which is arranged to cooperate with a ring 39 in relief interposed between the wheel 3 and the bottom 20, for a braking by detent during the rotation of the wheel 3. More particularly, this ring 39 in relief is an elastic ring. More particularly, this ring 39 in relief comprises at least one tab 38 of radial stop, arranged to cooperate in a complementary manner with a recess 28 of the housing 2.
Ainsi on réalise simplement un système de crantage pour la molette, plus agréable pour l'utilisateur qu'un simple frottement. Une telle bague 39 avec une répétition de bosses et creux est insérée dans le logement 2 avec la molette 3, laquelle est munie sur sa face inférieure d'au moins un relief 31 . Les figures 9, 10, 13, 14, montrent deux tels reliefs 31 constitués par des ergots en vé. Ainsi, lorsque la molette 3 tourne, chaque ergot 31 en vé vient sauter d'un creux de la bague à l'autre.  Thus one simply realizes a notching system for the wheel, more enjoyable for the user than a simple friction. Such a ring 39 with a repetition of bumps and depressions is inserted in the housing 2 with the wheel 3, which is provided on its underside with at least one relief 31. Figures 9, 10, 13, 14 show two such reliefs 31 constituted by V-shaped lugs. Thus, when the wheel 3 rotates, each lug 31 vee jumps from one hollow of the ring to another.
Dans une variante, la boîte 1 comporte un couvercle 19 ou une lunette ou un fond, ou encore une entretoise supplémentaire, ce composant étant agencé pour enfermer la molette 3 dans la boîte 1 , tel que visible sur la figure 5.  In a variant, the box 1 comprises a cover 19 or a telescope or a bottom, or an additional spacer, this component being arranged to enclose the wheel 3 in the box 1, as visible in FIG.
Le principe de l'invention est applicable à de nombreuses variantes, selon l'espace disponible dans la boîte de montre, l'épaisseur de celles-ci, et le nombre de fonctions à piloter. Ainsi la figure 17 illustre une boîte 1 avec deux ouvertures à 3h et à 9h, avec un poussoir 54 face à chacune de ces ouvertures. La molette 3 est accessible à 3h et 9h, et la présence d'un poussoir 54 de chaque côté permet une navigation dans les menus : activation de détection de rotation à 3h et 9h, puis « validation ok » à 3h et « retour » à 9h (ou l'inverse). The principle of the invention is applicable to many variants, depending on the space available in the watch case, the thickness thereof, and the number of functions to be controlled. Thus Figure 17 illustrates a box 1 with two openings at 3 o'clock and 9 o'clock, with a pusher 54 facing each of these openings. The wheel 3 is accessible at 3 and 9 o'clock, and the presence of a pusher 54 on each side allows navigation in the menus: rotation detection detection at 3 o'clock and 9 o'clock, then "validation ok" at 3 o'clock and "return" at 9am (or vice versa).
Une autre variante de boîte, illustrée aux figures 15 et 16, comporte quatre poussoirs non détaillés (dont éventuellement certains sont sans détection de rotation) et d'une géométrie adaptée de la molette pour se passer d'une pièce pour le verrouillage vertical (pas de lunette ni de bague de fond).  Another box variant, illustrated in FIGS. 15 and 16, comprises four non-detailed pushbuttons (some of which are without detection of rotation) and a suitable geometry of the wheel to dispense with a piece for vertical locking (not glasses or bottom ring).
Une autre variante encore concerne une boîte avec plusieurs molettes selon l'invention, superposées, chacune coopérant avec une ouverture propre, la figure 18 illustre un exemple à deux molettes 3X et 3Y, la boîte 1 ayant par exemple mais non limitativement deux ouvertures diamétralement opposées, une pour chaque molette. Le même logement 2 peut renfermer plusieurs molettes 3, ou bien chaque molette 3 peut disposer d'un logement 2 distinct.  Another variant also concerns a box with several wheels according to the invention, superimposed, each cooperating with a proper opening, Figure 18 illustrates an example with two wheels 3X and 3Y, the box 1 having for example but not limited to two diametrically opposed openings , one for each wheel. The same housing 2 may contain several wheels 3, or each wheel 3 may have a separate housing 2.
La figure 19 illustre une variante de boîte comportant des moyens capteurs 8 logés dans une corne 18, coopérant avec la surface périphérique 4 de la molette 3, soit par contact mécanique de friction ou d'entraînement direct si par exemple cette surface périphérique 4 est cannelée ou similaire, soit par interaction magnétique, ou autre.  FIG. 19 illustrates a box variant comprising sensor means 8 housed in a horn 18, cooperating with the peripheral surface 4 of the wheel 3, either by mechanical frictional contact or by direct drive if, for example, this peripheral surface 4 is fluted or the like, either by magnetic interaction, or the like.
La figure 20 illustre une variante où le poussoir comporte, à la place d'un patin, un pignon 57 coopérant avec une denture 37 que comporte alors la molette 3, ou qui est rapportée sur la molette, la tige poussoir permet alors la détection de la translation et de la rotation.  FIG. 20 illustrates a variant in which the pusher comprises, in place of a shoe, a pinion gear 57 cooperating with a toothing 37 which then comprises the wheel 3, or which is attached to the wheel, the push rod then allows the detection of translation and rotation.
L'invention concerne encore une montre 200 comportant une telle boîte 1 , agencée pour renfermer un mouvement d'horlogerie 100, dont l'affichage ou des fonctions horlogères sont agencées pour être commandés par des moyens capteurs 8 de la boîte 1 .  The invention also relates to a watch 200 comprising such a box 1, arranged to enclose a watch movement 100, whose display or watch functions are arranged to be controlled by sensor means 8 of the box 1.
Le mécanisme selon l'invention présente différents avantages.  The mechanism according to the invention has different advantages.
Tout d'abord ce système est sans risque pour l'étanchéité de la montre, les zones à étanchéifier concernant des systèmes connus et maîtrisés, tels que les liaisons glace/boîte et poussoir/boîte. Le capteur qui détecte la pression est monté sur le mouvement et est activé par le poussoir qui est facile à rendre étanche. Les capteurs qui détectent la rotation sont sur le mouvement. Comme la détection magnétique est sans contact, il n'y a pas de problème d'étanchéité. First of all this system is without risk for the waterproofness of the watch, the zones to be sealed concerning known and controlled systems, such as the links ice / box and push / box. The sensor that detects the pressure is mounted on the movement and is activated by the pusher which is easy to seal. The Sensors that detect rotation are on the move. As magnetic sensing is non-contact, there is no sealing problem.
En principe la fonction de répulsion de la molette peut être assurée par un poussoir qui ne débouche pas sur l'intérieur de la boîte ou de la carrure. En particulier dans les variantes illustrées, un dimensionnement approprié du crantage, de la force et la position des aimants, et de la position des capteurs magnétiques, permet la détection de la translation et la rotation de la molette. D'autres autres solutions sans contact, notamment galvaniques ou optiques, sont réalisables, mais de réalisation moins économique. L'utilisation d'une cloison déformable, pour une montre à boîte en matière plastique notamment, permet une détection de la translation sans contact.  In principle the repulsion function of the wheel can be provided by a pusher that does not open on the inside of the box or the middle part. In particular in the variants illustrated, an appropriate dimensioning of the notch, the force and the position of the magnets, and the position of the magnetic sensors, allows the detection of the translation and the rotation of the wheel. Other other non-contact solutions, in particular galvanic or optical, are feasible, but of less economic realization. The use of a deformable partition, for a watch plastic box in particular, allows a detection of the translation without contact.
Un autre avantage de l'invention est, dans la variante préférée mais non limitative de détection magnétique, la possibilité d'utilisation de la montre sous l'eau ou dans un environnement humide.  Another advantage of the invention is, in the preferred but nonlimiting variant of magnetic detection, the possibility of using the watch under water or in a humid environment.
La zone disponible pour que le doigt de l'utilisateur puisse actionner la molette est étendue, ce qui permet une bonne résolution de la détection: dans le cas d'une montre électronique ou d'une montre connectée ou intelligente, l'utilisateur n'est pas obligé de faire de nombreux tours pour faire défiler les menus (par rapport à une couronne électronique par exemple). Cet avantage vient du fait que la molette fait tout le tour du mouvement.  The area available for the finger of the user to actuate the wheel is extended, which allows a good resolution of the detection: in the case of an electronic watch or a connected or smart watch, the user does not is not obliged to make many laps to scroll through the menus (compared to an electronic crown for example). This advantage comes from the fact that the wheel is all around the movement.
Le système de crantage permet un bon ressenti à l'utilisateur pour déterminer de combien de pas il avance.  The notching system allows a good feeling to the user to determine how many steps he is moving forward.
L'invention est utilisable pour des couronnes, lunettes, et avec des molettes de différentes tailles : lunettes entourant tout ou partie du mouvement, ou bien mini- molettes empiétant le moins possible sur l'emprise géométrique du mouvement.  The invention is usable for crowns, glasses, and with wheels of different sizes: glasses surrounding all or part of the movement, or mini-wheels encroaching as little as possible on the geometric grip of the movement.
