Abstract

Watch has a winder rod (13) with helical fins (20, 20', 20'') over the inner part of its length. The fins engage with electrical contacts (14, 14') to open or close an electric connection to an electronic circuit (12) during rotation of the winder rod. This generates electrical signals that are used to correct the time, change the time-zone or alter the date.

Description

La présente invention concerne une montre du type montre-bracelet, comportant un affichage, par exemple un affichage analogique du temps, un circuit électronique de commande dudit affichage, une tige de mise à l'heure et au moins deux éléments de contact électrique, chacun d'eux ouvrant et fermant alternativement une connexion électrique dudit circuit électronique lors de la rotation de la tige de mise à l'heure de façon à générer au moins deux signaux électriques formés d'impulsions, transmis audit circuit électronique de commande.The present invention relates to a watch of the wristwatch type, comprising a display, for example an analog time display, a electronic circuit for controlling said display, a time-setting rod and at least two electrical contact elements, each of them opening and alternately closing an electrical connection of said electronic circuit during the rotation of the time-setting rod so as to generate at least two electrical signals formed by pulses, transmitted to said circuit control electronics.

Il existe actuellement de nombreuses montres et, en particulier, des montres-bracelets ayant un affichage analogique du temps et une commande électronique des fonctions de la montre. La demande de brevet anglais publiée sous le No. 2 070 815 et le brevet suisse No. 637 521 décrivent en particulier de telles montres.There are currently many watches and, in particular, wristwatches having an analog time display and a control electronic watch functions. English patent application published under No. 2,070,815 and Swiss Patent No. 637,521 describe in particular of such watches.

Ces montres comportent une tige de mise à l'heure ayant une section carrée sur une partie de sa longueur. Sur cette section carrée sont disposées deux cames qui peuvent notamment avoir un profil sensiblement carré, rectangulaire, triangulaire ou ellipsoïdal. Ces deux cames sont décalées angulairement l'une par rapport à l'autre et sont montées sur la tige de telle façon que la rotation de la tige de mise à l'heure entraíne la rotation des cames. Ces cames sont en outre disposées à proximité de deux lames conductrices élastiques qui ouvrent et ferment alternativement des connexions électriques lorsqu'elles sont déplacées sous l'effet de la rotation des cames. Ceci a pour conséquence que lors d'une rotation des cames, des signaux électriques formés d'impulsions sont générés, ces signaux transitant de l'état ouvert à l'état fermé et inversement, de manière décalée dans le temps. These watches have a time-setting rod having a square section over part of its length. On this square section are arranged two cams which can in particular have a substantially square profile, rectangular, triangular or ellipsoidal. These two cams are offset angularly with respect to each other and are mounted on the rod such so that the rotation of the time setting rod causes the rotation of cams. These cams are also arranged near two blades elastic conductors which open and close alternately electrical connections when moved by rotation cams. This has the consequence that during a rotation of the cams, electrical signals formed by pulses are generated, these signals passing through from the open state to the closed state and vice versa, offset in the time.

Le décalage angulaire des cames et le fait d'utiliser deux contacts électriques permettent de discriminer le sens de rotation de la tige de mise à l'heure, de façon connue.The angular offset of the cams and the fact of using two electrical contacts make it possible to discriminate the direction of rotation of the time-setting rod, known way.

La tige de mise à l'heure peut généralement être placée dans des positions longitudinales différentes, de façon à accéder à des fonctions différentes de la montre. Dans ce but, les cames sont coulissantes sur la section carrée de la tige de mise à l'heure de sorte qu'elles restent toujours en face des lames conductrices, quelle que soit la position longitudinale de la tige de mise à l'heure.The time-setting rod can usually be placed in positions different longitudinal ones, so as to access different functions of the watch. For this purpose, the cams are sliding on the square section of the time-setting rod so that they always remain opposite the blades regardless of the longitudinal position of the release rod time.

Ce mode de réalisation présente différents inconvénients. La section carrée de la tige de mise à l'heure doit avoir une taille suffisante pour recevoir les cames. De plus, ces cames occupent un volume important. Ceci pose des problèmes de place disponible, en particulier dans des montres de petites dimensions, telles que des montres de dames ou des montres très plates.This embodiment has various drawbacks. The square section of the time setting rod must be large enough to receive the cams. In addition, these cams occupy a large volume. This poses space problems, especially in small watches dimensions, such as ladies' watches or very flat watches.

La mise en place des cames sur la tige doit être réalisée selon une orientation donnée des cames, pour que la rotation de la tige dans un sens donné ne soit pas interprétée par le circuit électronique comme une rotation dans le sens inverse. D'autre part, au vu de la dimension des cames, il est clair que ce montage est complexe.The installation of the cams on the rod must be carried out according to a given cam orientation, so that the rotation of the rod in one direction given is not interpreted by the electronic circuit as a rotation In the opposite way. On the other hand, given the size of the cams, it is clear that this assembly is complex.

Le fait que les cames doivent rester en face des lames conductrices implique la mise en place d'un élément de maintien des cames dans une position longitudinale donnée, quelle que soit la position longitudinale de la tige de mise à l'heure. Cet élément complique également le montage. The fact that the cams must remain opposite the conductive blades implies the establishment of a cam retention element in a position given longitudinal, regardless of the longitudinal position of the rod setting the time. This element also complicates assembly.

Enfin, pour que les cames puissent coulisser longitudinalement sur la tige de mise à l'heure, il faut qu'elles soient montées sur celle-ci avec un certain jeu. Ceci introduit une hystérésis dans les signaux électriques de commande.Finally, so that the cams can slide longitudinally on the rod setting the time, they must be mounted on it with some play. This introduces hysteresis into the electrical control signals.

Cette hystérésis doit être traitée électroniquement, ce qui complique l'ensemble du traitement des signaux.This hysteresis must be treated electronically, which complicates the whole signal processing.

La présente invention se propose de pallier ces inconvénients en réalisant une montre comportant une tige de mise à l'heure ne portant pas de cames coulissantes, mais dont l'accès aux fonctions se fait de la même façon que pour les montres avec cames coulissantes.The present invention proposes to overcome these drawbacks by realizing a watch comprising a time-setting rod not carrying cams sliding, but access to functions is the same as for watches with sliding cams.

Ce but est atteint par une montre-bracelet telle que définie en préambule et caractérisée en ce que la tige de mise à l'heure comporte, sur au moins une partie de sa longueur, au moins un profil hélicoïdal coopérant avec lesdits éléments de contact électrique pour ouvrir et fermer alternativement une connexion électrique du circuit électronique lors de la rotation de ladite tige de mise à l'heure.This goal is achieved by a wristwatch as defined in the preamble and characterized in that the time-setting rod comprises, on at least one part of its length, at least one helical profile cooperating with said electrical contact elements for alternately opening and closing a electrical connection of the electronic circuit during the rotation of said rod time setting.

Selon un premier mode de réalisation, la tige de mise à l'heure comporte deux profils hélicoïdaux.According to a first embodiment, the time-setting rod comprises two helical profiles.

Selon un deuxième mode de réalisation, la tige de mise à l'heure comporte trois profils hélicoïdaux.According to a second embodiment, the time-setting rod comprises three helical profiles.

Ces profils hélicoïdaux sont avantageusement décalés angulairement d'une valeur constante.These helical profiles are advantageously offset angularly by one constant value.

Selon une forme de réalisation particulière de l'invention, chaque profil hélicoïdal a un pas d'hélice constant. According to a particular embodiment of the invention, each profile helical has a constant helix pitch.

Les éléments de contacts électriques sont de préférence séparés d'une distance donnée d.The electrical contact elements are preferably separated from one given distance d.

Selon un mode de réalisation préféré, le pas d'hélice des profils hélicoïdaux, le décalage angulaire de ces profils ainsi que la distance d séparant les éléments de contact électrique sont déterminés de façon à ce que les signaux électriques formés par l'ouverture et la fermeture alternative de chaque élément de contact électrique lors de la rotation à vitesse constante de la tige de mise à l'heure aient un rapport cyclique compris entre 30% et 70%, et avantageusement sensiblement égal à 50%.According to a preferred embodiment, the helical pitch of the helical profiles, the angular offset of these profiles as well as the distance d separating the electrical contact elements are determined so that the signals electric formed by the alternating opening and closing of each electric contact element during constant speed rotation of the rod time setting have a duty cycle of between 30% and 70%, and advantageously substantially equal to 50%.

Le pas des profils hélicoïdaux, le décalage angulaire de ces profils ainsi que la distance d séparant les éléments de contact électrique sont avantageusement déterminés de façon à ce que les signaux électriques formés par l'ouverture et la fermeture alternative de chaque élément de contact électrique lors de la rotation à vitesse constante de la tige de mise à l'heure soient sensiblement en quadrature.The pitch of the helical profiles, the angular offset of these profiles as well as the distance d separating the electrical contact elements are advantageously determined so that the electrical signals formed by the alternative opening and closing of each element of electrical contact when rotating the setting rod at constant speed the hour are substantially in quadrature.

Dans un mode de réalisation avantageux de l'invention, dans lequel la tige de mise à l'heure peut être placée dans au moins deux positions longitudinales différentes, chaque élément de contact électrique coopère avec ladite zone de la tige de mise à l'heure comportant au moins un profil hélicoïdal, pour toutes les positions longitudinales de la tige de mise à l'heure, excepté au maximum une position de cette tige.In an advantageous embodiment of the invention, in which the rod time setting can be placed in at least two longitudinal positions different, each electrical contact element cooperates with said zone of the time-setting rod comprising at least one helical profile, for all the longitudinal positions of the time-setting rod, except at maximum one position of this rod.

En référence aux figures et en particulier aux figures 1 et 2, la montre 10 selon la présente invention comporte notamment un affichage 11 tel qu'un affichage analogique ou numérique du temps, un circuit électronique 12 de commande dudit affichage, une tige de mise à l'heure 13 et deux éléments de contacts électriques 14, 14'. Dans les modes de réalisation représentés, ces éléments de contacts électriques sont des lames conductrices élastiques. With reference to the figures and in particular to Figures 1 and 2, the watch 10 according to the present invention notably comprises a display 11 such as a analog or digital time display, an electronic circuit 12 of control of said display, a time-setting rod 13 and two elements of electrical contacts 14, 14 '. In the embodiments shown, these electrical contact elements are elastic conductive strips.

La tige de mise à l'heure 13 est formée essentiellement de quatre zones. Une zone 15 comprend une couronne de mise à l'heure 16 accessible depuis l'extérieur du boítier de la montre et permettant à l'utilisateur de déplacer la tige de mise à l'heure en rotation et d'accéder ainsi à certaines fonctions de la montre. La tige comporte également deux zones cylindriques 17, 18 assurant un guidage de la tige de mise à l'heure aussi bien en rotation qu'en translation. Enfin, la tige de mise à l'heure comporte une zone 19 ayant au moins un profil hélicoïdal, cette zone étant nommée par la suite zone hélicoïdale 19.The time setting rod 13 is formed essentially from four zones. A zone 15 includes a time setting crown 16 accessible from the outside of the watch case and allowing the user to move the time-setting rod in rotation and thus access certain functions of the watch. The rod also has two cylindrical zones 17, 18 ensuring guidance of the time-setting rod both in rotation and in translation. Finally, the time setting rod has a zone 19 having at minus a helical profile, this area being referred to below as the area helical 19.

Dans les modes de réalisation illustrés par les figures 3A à 3C, qui sont des vues en coupe transversale de la zone hélicoïdale 19 de différentes tiges de mise à l'heure, cette zone comporte trois profils hélicoïdaux 20, 20', 20".In the embodiments illustrated by FIGS. 3A to 3C, which are cross-sectional views of the helical zone 19 of different rods of time setting, this area has three helical profiles 20, 20 ', 20 ".

La figure 3A illustre un premier mode de réalisation de la zone hélicoïdale 19 d'une tige de mise à l'heure. Cette zone est une surface réglée, ce qui signifie que chaque section perpendiculaire à l'axe longitudinal de la tige est délimitée par des segments de droite 21. Ce mode de réalisation permet une fabrication simple.FIG. 3A illustrates a first embodiment of the helical zone 19 a time-setting rod. This area is a ruled area, which means that each section perpendicular to the longitudinal axis of the rod is delimited by line segments 21. This embodiment allows a simple manufacturing.

Enfin, dans le mode de réalisation illustré par la figure 3C, ces sections sont délimitées par une courbe 23 légèrement bombée. Il est clair que d'autres formes de courbes pourraient également être choisies. La forme de ces sections est essentiellement déterminée par le procédé choisi pour la fabrication de la tige de mise à l'heure. Finally, in the embodiment illustrated in FIG. 3C, these sections are delimited by a slightly curved curve 23. It is clear that others curve shapes could also be chosen. The shape of these sections is essentially determined by the method chosen for the manufacture of the time-setting rod.

Le mode de réalisation illustré par la figure 3D comporte deux profils hélicoïdaux 24, 24' permettant de déplacer les éléments de contact électrique.The embodiment illustrated in FIG. 3D has two profiles helical 24, 24 'for moving the contact elements electric.

Le fonctionnement de la zone hélicoïdale 19 est expliqué en détail ci-dessous en référence aux figures 5, 6 et 7.The operation of the helical zone 19 is explained in detail below with reference to Figures 5, 6 and 7.

La figure 4 illustre les deux éléments de contacts électriques 14, 14'. Selon un mode de réalisation particulièrement avantageux, ces éléments de contacts sont formés de deux lames élastiques, électriquement conductrices et séparées d'une distance donnée d. Ces éléments de contacts sont de préférence réalisés en une seule pièce de façon que la distance d entre les deux lames ne puisse pas être modifiée lors du montage dans la montre. Il est toutefois également possible de réaliser les contacts de façon indépendante et d'assurer le maintien de la distance d par montage.Figure 4 illustrates the two electrical contact elements 14, 14 '. According to a particularly advantageous embodiment, these elements of contacts are formed by two elastic, electrically conductive blades and separated by a given distance d. These contact elements are preferably made in one piece so that the distance d between the two blades cannot be modified during assembly in the watch. he it is however also possible to make the contacts so independent and to maintain the distance d by mounting.

Les éléments de contacts électriques 14, 14' sont montés dans la montre de telle façon qu'ils ouvrent et ferment alternativement des connexions du circuit électrique du circuit électronique 12 en fonction de la partie du profil hélicoïdal qui déplace ces contacts. Ce montage des éléments de contact électrique est similaire au montage conventionnel comportant deux cames coulissantes.The electrical contact elements 14, 14 ′ are mounted in the watch of such that they alternately open and close circuit connections electrical circuit 12 as a function of the part of the profile helical which moves these contacts. This mounting of the contact elements electric is similar to conventional mounting with two cams sliding.

Les figures 5A, 5B et 5C illustrent une tige de mise à l'heure dans trois positions longitudinales possibles différentes.FIGS. 5A, 5B and 5C illustrate a time-setting rod in three different possible longitudinal positions.

Dans la figure 5A, la tige de mise à l'heure est entièrement poussée vers l'intérieur du boítier de la montre. Les deux contacts 14, 14' reposent sur la zone cylindrique 17 de la tige. La rotation de cette tige n'entraíne pas d'ouverture et/ou de fermeture des connexions électriques. Cette position correspond donc à une position "neutre" des contacts. Le diamètre de la zone cylindrique 17 implique que les connexions électriques sont toujours établies. Afin de minimiser la consommation électrique due à ces connexions, il est possible de prévoir l'arrêt de l'alimentation si les contacts restent immobiles pendant plus d'une durée prédéterminée.In FIG. 5A, the time-setting rod is fully pushed towards inside the watch case. The two contacts 14, 14 'rest on the cylindrical area 17 of the rod. The rotation of this rod does not cause opening and / or closing of electrical connections. This position therefore corresponds to a "neutral" position of the contacts. The diameter of the area cylindrical 17 implies that the electrical connections are always established. In order to minimize the power consumption due to these connections, it is it is possible to provide for the supply to be stopped if the contacts remain stationary for more than a predetermined period.

Dans la figure 5B, la tige de mise à l'heure est représentée dans une position légèrement déplacée vers l'extérieur du boítier de la montre. La zone hélicoïdale 19 se trouve en face des contacts 14, 14'. La rotation de la tige entraíne l'ouverture et la fermeture alternatives de chaque connexion. Cette ouverture et cette fermeture génèrent des signaux électriques formés d'impulsions, qui sont utilisés dans le circuit électronique 12 de la montre de façon à en commander différentes fonctions. La génération de signaux, de même que la discrimination du sens de rotation de la tige sont discutés ci-dessous en référence aux figures 7A et 7B. L'utilisation de ces signaux pour accéder à des fonctions de la montre, n'est pas discutée en détail, étant donné que ces éléments sont bien connus de l'homme du métier.In FIG. 5B, the time-setting rod is represented in a position slightly moved to the outside of the watch case. The area helical 19 is located opposite the contacts 14, 14 '. Rod rotation causes the alternative opening and closing of each connection. This opening and closing generate electrical signals formed of pulses, which are used in the electronic circuit 12 of the watch so as to control different functions. Signal generation, same as the discrimination of the direction of rotation of the rod are discussed below with reference to Figures 7A and 7B. The use of these signals for accessing watch functions, is not discussed in detail, being given that these elements are well known to those skilled in the art.

La figure 5C illustre la tige de mise à l'heure dans une position fortement déplacée vers l'extérieur du boítier de la montre. La zone hélicoïdale 19 reste en face des contacts 14, 14'. Ainsi, des signaux électriques formés d'impulsions peuvent de nouveau être générés par la rotation de la tige, avec un déphasage identique, donc indépendant de la position axiale de cette tige.Figure 5C illustrates the time setting rod in a strongly moved to the outside of the watch case. The helical zone 19 remains opposite the contacts 14, 14 '. So electrical signals formed pulses can again be generated by rotation of the rod, with an identical phase shift, therefore independent of the axial position of this rod.

Le mode de réalisation illustré par les figures 6A, 6B, 6C et 6D est similaire à celui des figures 5A, 5B et 5C. La tige de mise à l'heure 13 peut toutefois être déplacée dans quatre positions longitudinales différentes. Dans la position illustrée par la figure 6A, correspondant à la position de la tige poussée vers l'intérieur de la montre, les contacts 14, 14' sont disposés dans une zone cylindrique 17, mais ils ne sont pas déplacés par cette zone. Dans cette position, les connexions restent ouvertes en permanence et ne consomment donc pas d'énergie.The embodiment illustrated in FIGS. 6A, 6B, 6C and 6D is similar to that of FIGS. 5A, 5B and 5C. The time-setting rod 13 can however be moved to four different longitudinal positions. In the position illustrated by FIG. 6A, corresponding to the position of the rod pushed towards inside the watch, the contacts 14, 14 'are arranged in an area cylindrical 17, but they are not moved by this area. In this position, the connections remain permanently open and do not consume so no energy.

Dans les trois autres positions de la tige de mise à l'heure illustrées respectivement par les figures 6B, 6C et 6D, les contacts 14, 14' se trouvent en face de la zone hélicoïdale 19, ce qui permet, comme précédemment, de générer des signaux électriques par la rotation de la tige.In the other three positions of the time-setting rod illustrated respectively in FIGS. 6B, 6C and 6D, the contacts 14, 14 'are located opposite the helical zone 19, which, as before, allows generate electrical signals by rotating the rod.

Les figures 7A et 7B illustrent des signaux électriques obtenus lors d'une rotation à vitesse constante d'une tige de mise à l'heure telle qu'illustrée par la figure 3A par exemple.FIGS. 7A and 7B illustrate electrical signals obtained during a constant speed rotation of a time-setting rod as illustrated by Figure 3A for example.

La partie supérieure de ces figures illustrent un signal généré par l'élément de contact 14, alors que la partie inférieure illustre le signal généré par l'élément de contact 14'.The upper part of these figures illustrate a signal generated by the element contact 14, while the lower part illustrates the signal generated by the contact element 14 '.

Afin de permettre une discrimination fiable du sens de rotation, il est essentiel que les signaux générés lors de la rotation de la tige dans un sens, diffèrent de ceux générés lors de la rotation dans le sens opposé.In order to allow reliable discrimination of the direction of rotation, it is essential that the signals generated when the rod is rotated in one direction, differ of those generated when rotating in the opposite direction.

Afin d'optimiser cette discrimination, il est souhaitable, mais pas nécessaire, que la durée pendant laquelle chaque contact est fermé soit sensiblement égale à la durée pendant laquelle il est ouvert. On parle dans ce cas de rapport cyclique de 50%. De plus, il est également souhaitable que la commutation de l'un des contacts se produise sensiblement au milieu de la période pendant laquelle l'autre contact reste dans un état stable donné. A titre d'exemple, si une commutation sur un des contacts se produit toutes les 0,2 secondes, il est souhaitable que la commutation de l'autre contact se produise chaque fois 0,1 secondes après la commutation du premier contact. In order to optimize this discrimination, it is desirable, but not necessary, that the duration during which each contact is closed is substantially equal to the length of time it is open. We are talking in this case of 50% duty cycle. In addition, it is also desirable that the switching of one of the contacts occurs substantially in the middle of the period during which the other contact remains in a given stable state. AT As an example, if a switch to one of the contacts occurs every 0.2 seconds, it is desirable that the switching of the other contact is each time 0.1 seconds after switching the first contact.

Dans cette configuration, les signaux électriques sont dits "en quadrature". Pour un profil tel que celui des figures 3A, 3B et 3C, cette condition est remplie lorsque le pas de la section développée hélicoïdalement est tel que l'angle parcouru circulairement par une arrête sur une distance d est de 30°. Pour un profil tel que celui de la figure 3D, ce pas doit être de 45°. Cette configuration permet de minimiser le risque de fausse détection de commutation, et donc d'assurer que les signaux électriques seront interprétés correctement.In this configuration, the electrical signals are said to be "in quadrature". For a profile such as that of FIGS. 3A, 3B and 3C, this condition is filled when the pitch of the helically developed section is such that the angle traversed circularly by a stop over a distance d is 30 °. For a profile such as that in Figure 3D, this step must be 45 °. This configuration minimizes the risk of false detection of switching, and therefore ensuring that the electrical signals will be interpreted correctly.

La figure 7A illustre par exemple les signaux obtenus lors d'une rotation dans le sens horaire de la tige de mise à l'heure. D'après cette figure, on constate que la transition de l'état logique 0 à l'état logique 1 du premier contact est suivie d'une transition de l'état logique 0 à l'état logique 1 du deuxième contact.FIG. 7A illustrates for example the signals obtained during a rotation in clockwise of the time setting rod. From this figure, we can see that the transition from logical state 0 to logical state 1 of the first contact is followed by a transition from logical state 0 to logical state 1 of the second contact.

Lors de la rotation de la tige de mise à l'heure dans le sens anti-horaire, comme cela est illustré par la figue 7B, la transition de l'état logique 0 à l'état logique 1 du premier contact est suivie d'une transition de l'état logique 1 à l'état logique 0 du deuxième contact.When rotating the time-setting rod counterclockwise, as illustrated in fig 7B, the transition from logical state 0 to state logic 1 of the first contact is followed by a transition from logic state 1 to logic state 0 of the second contact.

En déterminant quelle transition se produit sur le deuxième contact lorsqu'une transition de l'état 0 à l'état 1 se produit sur le premier contact, il est possible de déterminer le sens de rotation de la tige.By determining what transition occurs on the second contact when a transition from state 0 to state 1 occurs on the first contact, it is possible to determine the direction of rotation of the rod.

La présente invention présente de nombreux avantages par rapport aux dispositifs de l'art antérieur.The present invention has many advantages over prior art devices.

La tige de mise à l'heure 13 est réalisée en une seule pièce et ne comporte pas d'éléments coulissants tels que des cames ou des pignons coulants. Ceci diminue le nombre de pièces à réaliser et simplifie considérablement le montage de l'ensemble de la montre.The time setting rod 13 is made in one piece and does not include no sliding elements such as cams or sliding gears. This reduces the number of parts to be produced and considerably simplifies the assembly of the entire watch.

Il est possible de prévoir que la zone hélicoïdale 19 soit une surface réglée, ce qui simplifie également la fabrication de cette tige.It is possible to provide for the helical zone 19 to be a regulated surface, which also simplifies the manufacture of this rod.

En outre, la section de la zone hélicoïdale 19 est grande par rapport à la section carrée des tiges de l'art antérieur. Ceci améliore la robustesse grâce à une résistance mécanique plus importante pour un encombrement réduit.In addition, the section of the helical zone 19 is large compared to the square section of the rods of the prior art. This improves robustness thanks to greater mechanical resistance for a reduced bulk.

La longueur totale de la tige peut également être réduite, puisqu'il n'est plus nécessaire de tenir compte des jeux liés au montage coulissant des cames. Ceci libère de la place dans la montre, ce qui est avantageux, en particulier dans des montres de petite dimension.The total length of the rod can also be reduced, since it is no longer it is necessary to take into account the play related to the sliding mounting of the cams. This frees up space in the watch, which is advantageous, in particular in small watches.

Le positionnement des contacts 14, 14' n'a pas besoin d'être particulièrement précis. Il suffit que la distance d entre les contacts concorde avec le pas de l'hélice de la zone hélicoïdale de la tige. Ceci est particulièrement simple à garantir du fait des procédés de fabrication généralement utilisés pour réaliser les contacts.The positioning of the contacts 14, 14 'need not be particularly specific. It is enough that the distance d between the contacts agrees with the pitch of the helix of the helical area of the rod. This is particularly simple to guarantee due to the manufacturing processes generally used to make the contacts.

Enfin, étant donné qu'il n'y a pas de jeu angulaire entre les zones engendrant un déplacement des contacts et la rotation de la tige, les signaux électriques ne présentent pas d'hystérésis et sont plus faciles à traiter. Ceci permet également une simplification du circuit électronique de traitement.Finally, since there is no angular play between the zones generating displacement of the contacts and rotation of the rod, the electrical signals do not have hysteresis and are easier to treat. this allows also a simplification of the electronic processing circuit.

La présente invention n'est pas limitée aux modes de réalisation décrits, mais s'étend à toute variante ou modification évidente pour un homme du métier. En particulier, la forme de la zone hélicoïdale peut être modifiée, pour autant qu'elle permette de déplacer les contacts lors de la rotation de la tige. Il est en effet possible de prévoir deux ou quatre profils hélicoïdaux par exemple au lieu des trois profils illustrés dans les figures 3A à 3C. Il est également possible de n'utiliser qu'un seul contact s'il n'est pas nécessaire de discriminer le sens de rotation de la tige. Ceci permettrait de déterminer un déplacement en translation de la tige, puisqu'en l'absence de rotation, un tel déplacement produirait une inversion de l'état du contact.The present invention is not limited to the embodiments described, but extends to any variant or modification obvious to a person skilled in the art. In particular, the shape of the helical area can be changed, provided that that it allows to move the contacts during the rotation of the rod. It is indeed possible to provide two or four helical profiles for example at location of the three profiles illustrated in FIGS. 3A to 3C. he is also possible to use only one contact if it is not necessary to discriminate the direction of rotation of the rod. This would determine a displacement in translation of the rod, since in the absence of rotation, such displacement would produce an inversion of the state of the contact.

De plus, le pas de l'hélice peut varier le long de la zone hélicoïdale. Ceci permettrait de déterminer la position axiale de la tige de mise à l'heure. En effet, le décalage entre le signal généré par l'un des contacts par rapport au décalage du signal généré par l'autre contact est différent si le pas de l'hélicoïde dans deux zones hélicoïdales est différent. En particulier, les signaux peuvent être en quadrature lorsque la tige de mise à l'heure est dans une première position axiale et ne pas être en quadrature lorsque la tige est dans une deuxième position axiale. L'analyse des signaux permettrait ainsi de déterminer dans quelle position axiale se trouve la tige de mise à l'heure.In addition, the pitch of the propeller can vary along the helical zone. This would determine the axial position of the time setting rod. In effect, the offset between the signal generated by one of the contacts compared to the offset of the signal generated by the other contact is different if the pitch of the helicoid in two helical zones is different. In particular, signals can be quadrature when the time setting rod is in a first axial position and not be in quadrature when the rod is in a second axial position. Signal analysis would thus allow determine the axial position of the time setting rod.
