Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention se rapporte à un système d'affichage des horaires de marée permettant d'indiquer au moins l'horaire de la prochaine marée haute.The present invention relates to a system for displaying tide times making it possible to indicate at least the time of the next high tide.

ARRIÈRE-PLAN TECHNIQUE DE L'INVENTIONTECHNICAL BACKGROUND OF THE INVENTION

Il a déjà été proposé des mécanismes d'affichage des marées. Toutefois, ces mécanismes dépendent généralement d'un autre mécanisme comme par exemple d'affichage de phase de lune ce qui occasionne des difficultés à réaliser un affichage fiable.Mechanisms for displaying the tides have already been proposed. However, these mechanisms generally depend on another mechanism such as, for example, a moon phase display, which causes difficulties in producing a reliable display.

Un tel mécanisme est divulgué par exemple dans le document EP 1 729 186 dans lequel un dispositif de correction règle simultanément le mobile des marées et la roue de la phase de lune ce qui rend l'ensemble très encombrant. Dans ce document, c'est le cycle de lunaison qui contrôle le déplacement du mobile des marées à raison d'une dent tous les jours ce qui empêche d'avoir l'horaire effectif de la prochaine marée haute au fur et à mesure des marées quotidiennes. En outre, si la correction est faite lorsque le doigt est en face d'une dent de la roue à étoile, il y a un risque de blocage à cause du mouvement en opposition de l'un par rapport à l'autre.Such a mechanism is disclosed for example in the document EP 1 729 186 in which a correction device simultaneously regulates the mobile of the tides and the wheel of the moon phase, which makes the assembly very cumbersome. In this document, it is the lunation cycle that controls the movement of the tidal mobile at the rate of one tooth every day, which prevents having the effective time of the next high tide as the tides change. daily. In addition, if the correction is made when the finger is in front of a tooth of the star wheel, there is a risk of jamming because of the movement in opposition of one relative to the other.

Le document US 2 677 928 A divulgue un système d'affichage des horaires des marées dans lequel un mécanisme qui assure plusieurs positions stables est disposé à l'extérieur d'un disque afficheur.The document US 2,677,928 A discloses a system for displaying tide times in which a mechanism which provides several stable positions is arranged outside a display disc.

RÉSUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention a pour but de proposer un système d'affichage des horaires de marée dédié afin d'améliorer sa fiabilité d'affichage et de simplifier sa correction et dont la compacité améliorée facilite son intégration dans une pièce d'horlogerie sans pour autant influencer la marche du mouvement horloger ou dérégler les autres mécanismes d'affichage.The object of the invention is to propose a dedicated tide time display system in order to improve its display reliability and to simplify its correction and whose improved compactness facilitates its integration into a timepiece without influencing the rate of the watch movement or disturb the other display mechanisms.

À cet effet, l'invention se rapporte à un système d'affichage des horaires de marée comportant un dispositif d'affichage dont l'élément afficheur indique l'horaire d'au moins la prochaine marée haute, dans lequel le dispositif d'affichage comporte un mécanisme à plusieurs positions stables permettant, à chaque saut entre deux positions stables, l'avancée de l'élément afficheur d'un déplacement prédéterminé afin de pouvoir indiquer, par saut instantané, l'horaire de la prochaine marée haute, le mécanisme à plusieurs positions stables étant supporté par le corps de l'élément afficheur afin de limiter le nombre de pièces du mécanisme.To this end, the invention relates to a system for displaying tide times comprising a display device whose display element indicates the time of at least the next high tide, in which the display device comprises a mechanism with several stable positions allowing, with each jump between two stable positions, the advancement of the display element by a predetermined displacement in order to be able to indicate, by instantaneous jump, the time of the next high tide, the mechanism with several stable positions being supported by the body of the display element in order to limit the number of parts of the mechanism.

Avantageusement selon l'invention, le système d'affichage est totalement indépendant et peut être aisément couplé par exemple au rouage de comptage d'un mouvement horloger. Le corps de l'élément afficheur peut être assimilé à un pont secondaire afin de supporter le mécanisme à plusieurs positions stables et ainsi limiter au maximum l'espace nécessaire au système d'affichage. L'élément afficheur étant à saut instantané, l'horaire de la prochaine marée sera toujours correctement affiché au contraire des affichages trainants qui modifient en continu l'horaire de marée. Enfin, le système évite avantageusement tout arcboutement ou accrochage de ses pièces quels que soient sa position et son orientation, même lors des phases de correction de l'affichage des marées ou lors de la correction d'un autre affichage du mouvement horloger tel que la date ou l'heure.Advantageously according to the invention, the display system is completely independent and can be easily coupled, for example, to the counting train of a watch movement. The body of the display element can be likened to a secondary bridge in order to support the mechanism at several stable positions and thus limit the maximum space required for the display system. The display element being an instantaneous jump, the next tide time will always be correctly displayed, unlike dragging displays which continuously modify the tide time. Finally, the system advantageously avoids any bracing or snagging of its parts regardless of its position and orientation, even during the phases of correction of the tide display or during the correction of another display of the watch movement such as the date or time.

L'invention peut également comporter l'une ou plusieurs des caractéristiques optionnelles suivantes, prises seules ou en combinaison.The invention may also include one or more of the following optional features, taken alone or in combination.

Le mécanisme à plusieurs positions stables peut comporter un organe de commande monté pivotant sur le corps de l'élément afficheur et destiné à imposer un déplacement relatif à un ensemble étoile - sautoir monté sur un pivot solidaire du corps de l'élément afficheur afin de réaliser un saut entre deux positions stables. L'organe de commande est préférentiellement couplé à un mouvement horloger afin de compter la durée des marées. L'organe de commande impose, de manière préférée, un déplacement relatif après chaque marée haute.The mechanism with several stable positions may comprise a control member pivotally mounted on the body of the display element and intended to impose a movement relative to a star assembly - jumper mounted on a pivot integral with the body of the display element in order to achieve a jump between two stable positions. The control member is preferably coupled to a watch movement in order to count the duration of the tides. The control member preferably imposes a relative movement after each high tide.

Le mécanisme à plusieurs positions stables peut comporter une couronne montée solidaire du corps de l'élément afficheur de manière coaxiale à l'organe de commande et comprenant une denture interne dans laquelle s'engrène un pignon solidaire de l'ensemble étoile - sautoir afin de guider la rotation de l'ensemble étoile - sautoir autour de l'organe de commande. On comprend que l'ensemble étoile - sautoir - pignon forme un satellite entraînant l'élément afficheur (faisant office de porte-satellite) entre l'intérieur de la couronne (formant un planétaire extérieur) et l'organe de commande (formant un planétaire intérieur qui n'est pas en contact permanent avec l'ensemble étoile - sautoir - pignon).The mechanism with several stable positions may comprise a crown mounted integral with the body of the display element coaxially with the control member and comprising internal toothing in which meshes a pinion integral with the star-jumper assembly in order to guiding the rotation of the star - jumper assembly around the control device. It is understood that the star - jumper - pinion assembly forms a satellite driving the display element (acting as a planet carrier) between the inside of the crown (forming an outer sun gear) and the control member (forming a sun gear interior which is not in permanent contact with the star - jumper - pinion assembly).

L'élément afficheur peut être un disque avec un repère de marée haute tournant à l'intérieur d'un limbe gradué sur douze heures afin de simplifier l'affichage à un horaire de marée haute (également appelé midi lunaire) et un horaire de marée basse (également appelé minuit lunaire). Cette configuration rend plus rapide la correction de l'élément afficheur en ne distinguant pas le matin de l'après-midi solaire et rend plus précise la détermination de l'horaire de marée haute en affichant un limbe de douze heures sur trois cent soixante degrés.The display element may be a disc with a rotating high tide marker inside a twelve-hour graduated limb to simplify the display at a high tide time (also called lunar noon) and a tide time. low (also called lunar midnight). This configuration makes the correction of the display element faster by not distinguishing the morning from the solar afternoon and makes the determination of the high tide time more precise by displaying a limb of twelve hours over three hundred and sixty degrees. .

Le déplacement prédéterminé de l'élément afficheur peut correspondre à une variation de sensiblement vingt-cinq minutes et quatorze secondes ce qui correspond à un changement de l'horaire de la marée haute toutes les douze heures, vingt-cinq minutes et quatorze secondes qui représente la moyenne des durées observées entre deux marées hautes.The predetermined displacement of the display element can correspond to a variation of substantially twenty-five minutes and fourteen seconds which corresponds to a change in the high tide time every twelve hours, twenty-five minutes and fourteen seconds which represents the average of the durations observed between two high tides.

Le système d'affichage peut comporter en outre un dispositif de correction couplé au dispositif d'affichage par un organe différentiel afin de pouvoir corriger à tout moment la position de l'élément d'affichage. On comprend donc que l'ensemble étoile - sautoir - pignon peut ainsi être déplacé soit par le dispositif de correction soit par l'organe de commande.The display system may further comprise a correction device coupled to the display device by a differential member in order to be able to correct the position of the display element at any time. It is therefore understood that the star/jumper/pinion assembly can thus be moved either by the correction device or by the control member.

L'organe différentiel peut être formé par la couronne du mécanisme à plusieurs positions stables comportant en outre une denture externe afin de commander un mouvement relatif entre la couronne et l'ensemble étoile - sautoir destiné à déplacer l'élément afficheur.The differential member may be formed by the crown of the mechanism with several stable positions further comprising external toothing in order to control a relative movement between the crown and the star/jumper assembly intended to move the display element.

Le système d'affichage peut comporter un rouage de correction couplé à la denture externe de la couronne et commandé par un organe de correction afin de modifier la position de l'élément d'affichage. Typiquement, l'organe de correction, tel qu'une couronne en saillie de la pièce d'horlogerie, permet à l'utilisateur de régler l'élément afficheur sur l'horaire effectif de la prochaine marée haute de l'endroit où il réside.The display system may include a correction gear train coupled to the external toothing of the crown and controlled by a correction member in order to modify the position of the display element. Typically, the corrective device, such as a crown protruding from the timepiece, allows the user to adjust the display element to the effective time of the next high tide of the place where he resides. .

L'invention se rapporte également à une pièce d'horlogerie comportant un mouvement horloger destiné à afficher au moins une valeur horaire, caractérisée en ce qu'elle comporte en outre un système d'affichage des horaires de marée tel que présenté plus haut. Préférentiellement, le dispositif d'affichage comporte un rouage de transmission couplé au mouvement horloger afin d'entraîner le mécanisme à plusieurs positions stables.The invention also relates to a timepiece comprising a timepiece movement intended to display at least one time value, characterized in that it further comprises a system for displaying the tide times as presented above. Preferably, the display device comprises a transmission train coupled to the watch movement in order to drive the mechanism to several stable positions.

DESCRIPTION DÉTAILLÉE D'AU MOINS UN MODE DE RÉALISATION DE L'INVENTIONDETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT OF THE INVENTION

Sur les différentes figures, les éléments identiques ou similaires portent les mêmes références, éventuellement additionné d'un indice. La description de leur structure et de leur fonction n'est donc pas systématiquement reprise.In the various figures, identical or similar elements bear the same references, possibly with the addition of an index. The description of their structure and function is therefore not systematically repeated.

Dans tout ce qui suit, les orientations sont les orientations de la pièce d'horlogerie. En particulier, les termes « supérieur », « inférieur », « gauche », « droit », « au-dessus », « en-dessous », « vers l'avant » et « vers l'arrière » s'entendent généralement par rapport au porté de la pièce d'horlogerie.In all that follows, the orientations are the orientations of the timepiece. In particular, the terms "upper", "lower", "left", "right", "above", "below", "forward" and "backward" generally mean relative to the wear of the timepiece.

Par « pièce d'horlogerie », on entend tous les types d'instruments de mesure ou de comptage du temps tels que les pendules, les pendulettes et les montres.By “timepiece” is meant all types of instruments for measuring or counting time such as clocks, clocks and watches.

Par « mouvement horloger », on entend tous les types de mécanisme capable de compter le temps qu'ils soient alimentés à base d'énergie mécanique (par exemple un barillet) et/ou électrique (par exemple une batterie).By “watch movement” is meant all types of mechanism capable of counting the time whether they are powered based on mechanical energy (for example a barrel) and/or electricity (for example a battery).

L'invention se rapporte à une pièce 1 d'horlogerie comportant un mouvement 3 horloger destiné à afficher au moins une valeur 2 horaire (des aiguilles des heures et des minutes sont représentées à la figure 1) et un système 5 d'affichage des horaires 4 de marée tel que présenté ci-dessous. Selon l'invention, le système 5 d'affichage des horaires 4 de marée est couplé au mouvement 3 horloger afin d'entraîner les éléments du système 5 d'affichage des horaires 4 de marée.The invention relates to a timepiece 1 comprising a watch movement 3 intended to display at least one time value 2 (hour and minute hands are represented on the figure 1 ) and a system 5 for displaying tide times 4 as presented below. According to the invention, the system 5 for displaying the tide times 4 is coupled to the watch movement 3 in order to drive the elements of the system 5 for displaying the tide times 4.

Dans l'exemple de la figure 1, l'élément 7 afficheur du système 5 d'affichage des horaires 4 de marée est préférentiellement un disque 6 avec un repère de marée haute tournant à l'intérieur d'un limbe 8 gradué sur douze heures (monté sur le cadran 9 à la figure 1) afin de simplifier l'affichage à un horaire 4 de marée haute et un horaire de marée basse. Cette configuration rend plus rapide la correction de l'élément 7 afficheur en ne distinguant pas le matin de l'après-midi solaire et rend plus précise la détermination de l'horaire 4 de marée haute en s'affichant sur un limbe 8 de douze heures sur trois cent soixante degrés.In the example of the figure 1 , the display element 7 of the system 5 for displaying the tide times 4 is preferably a disk 6 with a high tide mark rotating inside a limb 8 graduated over twelve hours (mounted on the dial 9 at the figure 1 ) in order to simplify the display at a time 4 of high tide and a time of low tide. This configuration makes the correction of the display element 7 faster by not distinguishing the morning from the solar afternoon and makes the determination of the high tide time 4 more precise by being displayed on a limb 8 of twelve hours at three hundred and sixty degrees.

Avantageusement selon l'invention, la pièce 1 d'horlogerie comporte un organe 10 de correction (illustré à la figure 1 par une couronne en saillie du boîtier de la pièce 1 d'horlogerie) permettant à l'utilisateur de régler l'élément 7 afficheur sur l'horaire effectif de la prochaine marée haute de l'endroit où il réside. L'organe 10 de correction peut se situer à différents endroits sur le boitier 1 et il peut également être intégré dans un autre organe de commande tel qu'une couronne de remontoir et/ou de mise à l'heure.Advantageously according to the invention, the timepiece 1 comprises a correction member 10 (illustrated in figure 1 by a crown projecting from the case of the timepiece 1) allowing the user to adjust the display element 7 to the actual time of the next high tide in the place where he resides. The correction member 10 can be located at different places on the case 1 and it can also be integrated into another control member such as a winding and/or time-setting crown.

Le système 5 d'affichage des horaires 4 de marée comporte un dispositif 11 d'affichage permettant de déplacer le disque 6 de l'élément 7 afficheur pour indiquer l'horaire 4 d'au moins la prochaine marée haute. Dans l'exemple illustré à la figure 1, préférentiellement, le disque 6 de l'élément 7 afficheur comporte un repère triangulaire pour indiquer uniquement l'horaire 4 de la prochaine marée haute et, incidemment, celui de la prochaine marée basse par une indication sensiblement symétrique par rapport au centre du disque 6. En effet, la marée basse suivante interviendra environ six heures et 12 minutes après l'horaire 4 de la marée haute ce qui correspond à une indication sensiblement décalée de cent quatre-vingts degrés sur le limbe 8 par rapport à celle indiquée pour l'horaire 4 de la marée haute.The system 5 for displaying the tide times 4 comprises a display device 11 making it possible to move the disk 6 of the display element 7 to indicate the time 4 of at least the next high tide. In the example shown in figure 1 , preferably, the disc 6 of the display element 7 comprises a triangular mark to indicate only the schedule 4 of the next high tide and, incidentally, that of the next low tide by an indication substantially symmetrical with respect to the center of the disk 6. Indeed, the next low tide will occur approximately six hours and 12 minutes after the high tide schedule 4, which corresponds to an indication substantially shifted by one hundred and eighty degrees on limb 8 with respect to that indicated for time 4 of high tide.

Le dispositif 11 d'affichage comporte un mécanisme 13 à plusieurs positions stables permettant, à chaque saut entre deux positions stables, l'avancée de l'élément 7 afficheur d'un déplacement prédéterminé afin de pouvoir indiquer, par saut instantané, l'horaire 4 de la prochaine marée haute. Avantageusement selon l'invention, le mécanisme 13 à plusieurs positions stables est supporté par le corps de l'élément 7 afficheur afin de limiter le nombre de pièces du mécanisme 13.The display device 11 comprises a mechanism 13 with several stable positions allowing, at each jump between two stable positions, the advance of the display element 7 by a predetermined movement in order to be able to indicate, by instantaneous jump, the time 4 of the next high tide. Advantageously according to the invention, the mechanism 13 with several stable positions is supported by the body of the display element 7 in order to limit the number of parts of the mechanism 13.

De manière avantageuse selon l'invention, le système 5 d'affichage est totalement indépendant et peut être aisément couplé par exemple au rouage (non représenté) de comptage d'un mouvement 3 horloger. Le corps de l'élément 7 afficheur, c'est-à-dire le disque 6 à la figure 1, peut être assimilé à un pont secondaire afin de supporter le mécanisme 13 à plusieurs positions stables et ainsi limiter au maximum l'espace nécessaire au système 5 d'affichage. L'élément 7 afficheur étant à saut instantané, l'horaire 4 de la prochaine marée sera toujours correctement affiché au contraire des affichages trainants qui modifient en continu l'horaire de marée.Advantageously according to the invention, the display system 5 is completely independent and can be easily coupled for example to the gear train (not shown) for counting a watch movement 3. The body of the display element 7, that is to say the disc 6 at the figure 1 , can be likened to a secondary bridge in order to support the mechanism 13 in several stable positions and thus minimize the space necessary for the display system 5 . The display element 7 being an instantaneous jump, the schedule 4 of the next tide will always be correctly displayed, unlike the dragging displays which continuously modify the tide schedule.

Dans l'exemple illustré aux figures 2 à 5, le mécanisme 13 à plusieurs positions stables comporte un organe 15 de commande qui est monté pivotant sur le corps de l'élément 7 afficheur tel que le dessous du disque 6. Comme visible à la figure 2, l'organe 15 de commande est monté sensiblement au centre du dessous du disque 6 et comporte un mobile 16 monté sur le pivot A solidaire du disque 6. Le mobile 16 comporte principalement un doigt 17 et un pignon 18 solidaires à rotation. Comme illustré aux figures 2 et 3, le pignon 18 est couplé à un rouage 19 de transmission, lui-même couplé au mouvement 3 horloger afin d'entraîner le mécanisme 13 à plusieurs positions stables. Préférentiellement, l'organe 15 de commande est couplé à la roue des heures (non représentée) du mouvement 3 horloger afin de compter la durée des marées en effectuant deux rotations par jour.In the example shown in figures 2 to 5 , the mechanism 13 with several stable positions comprises a control member 15 which is pivotally mounted on the body of the display element 7 such as the underside of the disc 6. figure 2 , the control member 15 is mounted substantially in the center of the underside of the disc 6 and comprises a mobile 16 mounted on the pivot A integral with the disc 6. The mobile 16 mainly comprises a finger 17 and a pinion 18 integral in rotation. As shown in figure 2 and 3 , the pinion 18 is coupled to a transmission cog 19, itself coupled to the watch movement 3 in order to drive the mechanism 13 to several stable positions. Preferably, the control member 15 is coupled to the hour wheel (not shown) of the watch movement 3 in order to count the duration of the tides by performing two rotations per day.

Le doigt 17 est destiné par contact à imposer un déplacement relatif à un ensemble étoile 21 - sautoir 20, c'est-à-dire imposer, par contact contre l'une des sept dents de l'étoile 21, un déplacement relatif entre l'étoile 21 et le sautoir 20 par déplacement élastique de ce dernier. Dans l'exemple illustré aux figures 2 à 5, l'étoile 21 est montée sur un pivot B solidaire du corps de l'élément 7 afficheur tel que le dessous du disque 6 tandis que le sautoir 20 est fixé, dans cet exemple et de manière classique, à l'aide d'un pivot C et une vis D au corps de l'élément 7 afficheur tel que le dessous du disque 6 afin de réaliser un saut entre deux positions stables, c'est-à-dire entre deux positions adjacentes dans lesquelles le sautoir 20 est situé entre deux dents de l'étoile 21. Bien entendu, le sautoir 20 ou un autre type d'élément élastique similaire peut également être fabriqué en une seule pièce avec l'élément 7 afficheur par exemple en utilisant un procédé d'impression tridimensionnelle à poudre ou à liquide, un procédé LIGA (parfois appelé électroformage, c'est-à-dire une photolithographie d'un moule suivi d'un dépôt électrolytique dans le creux du moule) ou encore un procédé DRIE (c'est-à-dire un gravage ionique réactif profond comportant une photolithographie d'un masque suivi d'un gravage sensiblement anisotrope à travers les trous du masque). Enfin, l'étoile 21 est surmonté et solidaire en rotation d'un pignon 22 à treize dents.The finger 17 is intended by contact to impose a relative displacement on a star 21 - jumper 20 assembly, that is to say to impose, by contact against one of the seven teeth of the star 21, a relative displacement between the star 21 and jumper 20 by elastic displacement of the latter. In the example shown in figures 2 to 5 , the star 21 is mounted on a pivot B secured to the body of the display element 7 such as the underside of the disc 6 while the jumper 20 is fixed, in this example and in a conventional manner, using a pivot C and a screw D to the body of the display element 7 such as the underside of the disk 6 in order to make a jump between two stable positions, that is to say between two adjacent positions in which the jumper 20 is located between two teeth of the star 21. Of course, the jumper 20 or another type of similar elastic element can also be manufactured in one piece with the display element 7 for example using a three-dimensional powder or liquid printing process, a LIGA process (sometimes called electroforming, i.e. a photolithography of a mold followed by electrolytic deposition in the cavity of the mold) or even a DRIE process (that is to say deep reactive ion etching comprising photolithography of a mask followed by substantially anisotropic etching at through the holes in the mask). Finally, the star 21 is surmounted and integral in rotation with a pinion 22 with thirteen teeth.

L'organe 15 de commande impose, de manière préférée, un déplacement relatif après chaque marée haute. Le doigt 17 est ainsi synchronisé avec les aiguilles de la valeur horaire 2 ainsi qu'avec la position de l'étoile 21 par rapport au disque 6. Il est préféré selon l'invention que le saut instantané de l'horaire 4 de marée se fasse directement après l'arrivée de la marée haute, c'est-à-dire typiquement après une durée comprise entre 1 seconde et 5 minutes comme par exemple 5 secondes, 15 secondes, 30 secondes, 45 secondes, 1 minute, 1,5 minute, 2 minutes, 3 minutes ou 4 minutes.The control member 15 preferably imposes a relative displacement after each high tide. The finger 17 is thus synchronized with the hands of the time value 2 as well as with the position of the star 21 with respect to the disc 6. It is preferred according to the invention that the instantaneous jump of the tide time 4 is done directly after the arrival of high tide, i.e. typically after a period of between 1 second and 5 minutes such as 5 seconds, 15 seconds, 30 seconds, 45 seconds, 1 minute, 1.5 minute, 2 minutes, 3 minutes or 4 minutes.

Dans l'exemple illustré aux figures 2 à 5, le mécanisme 13 à plusieurs positions stables comporte une couronne 23 montée solidaire du corps de l'élément 7 afficheur tel que le dessous du disque 6 de manière coaxiale à l'organe 15 de commande. La couronne 23 comprend une denture 24 interne de cinquante-trois dents dans laquelle s'engrène le pignon 22 solidaire de l'étoile 21 afin de guider la rotation de l'ensemble étoile 21 - sautoir 20 autour de l'organe 15 de commande. On comprend que l'ensemble étoile 21 - pignon 22 forme un satellite entraînant l'élément 7 afficheur (faisant office de porte-satellite) entre l'intérieur de la couronne 23 (formant un planétaire extérieur) et l'organe 15 de commande (formant un planétaire intérieur qui n'est pas en contact permanent avec l'étoile 21).In the example shown in figures 2 to 5 , the mechanism 13 with several stable positions comprises a crown 23 mounted integral with the body of the display element 7 such as the underside of the disc 6 coaxially with the control member 15 . The crown 23 comprises an internal set of teeth 24 of fifty-three teeth in which the pinion 22 integral with the star 21 meshes in order to guide the rotation of the star 21 - jumper 20 assembly around the control member 15 . It is understood that the star 21 - pinion 22 assembly forms a satellite driving the display element 7 (acting as a planet carrier) between the inside of the ring gear 23 (forming an outer sun gear) and the control member 15 ( forming an inner planetary which is not in permanent contact with the star 21).

Le déplacement prédéterminé du saut instantané correspond préférentiellement à une variation de sensiblement vingt-cinq minutes et quatorze secondes ce qui correspond à un changement de l'horaire 4 de la marée haute toutes les douze heures, vingt-cinq minutes et quatorze secondes. En effet, cette valeur représente la moyenne des durées observées entre deux marées hautes. Ce principe d'affichage est le moyen le plus simple pour visualiser l'horaire 4 des marées qui ont lieu au même moment mais pas au même endroit. En réalité, les marées représentent des « grandes vagues » ou des ondes consécutives qui déferlent le long des littoraux de sorte que la marée haute, c'est-à-dire le niveau le plus élevé atteint par la mer au cours d'un cycle de marée, varie en fonction de la forme du littoral. De plus, la durée de l'intervalle qui sépare deux marées n'est pas constamment la même. Elle est d'environ douze heures, vingt-cinq minutes et quatorze secondes. Cette durée moyenne entre les deux marées est dépendant de la révolution lunaire qui est d'environ 24 heures 50 minutes et 28 secondes, et qui fait que chaque jour le moment de la marée haute ou de la marée basse retarde d'environ trois quarts d'heure en un lieu donné par rapport à l'heure locale affiché (éventuellement corrigé par un changement d'heure local comme par exemple le basculement entre une heure d'été et une heure d'hiver suivant les saisons).The predetermined displacement of the instantaneous jump preferably corresponds to a variation of substantially twenty-five minutes and fourteen seconds, which corresponds to a change in the schedule 4 of the high tide every twelve hours, twenty-five minutes and fourteen seconds. Indeed, this value represents the average of the durations observed between two high tides. This principle of display is the simplest way to view the schedule 4 of the tides which take place at the same time but not in the same place. In reality, the tides represent "big waves" or consecutive waves which break along the coasts so that the high tide, that is to say the highest level reached by the sea during a cycle tidal, varies according to the shape of the coastline. Moreover, the duration of the interval which separates two tides is not always the same. It is approximately twelve hours, twenty-five minutes and fourteen seconds. This average duration between the two tides is dependent on the lunar revolution which is about 24 hours 50 minutes and 28 seconds, and which means that each day the moment of high tide or low tide is delayed by about three quarters of a hour. time in a given place in relation to the local time displayed (possibly corrected by a change of local time such as for example switching between summer time and winter time depending on the season).

Dans l'exemple illustré aux figures 2 à 5, le système 5 d'affichage comporte en outre un dispositif 25 de correction couplé au dispositif 11 d'affichage par un organe 27 différentiel afin de pouvoir corriger à tout moment la position de l'élément 7 d'affichage en évitant avantageusement tout arcboutement ou accrochage des pièces du mouvement 3 horloger quels que soient leur position et leur orientation. On comprend donc que l'ensemble étoile 21 - sautoir 20 - pignon 22 peut ainsi être déplacé soit par le dispositif 25 de correction soit par l'organe 15 de commande.In the example shown in figures 2 to 5 , the display system 5 further comprises a correction device 25 coupled to the display device 11 by a differential member 27 in order to be able to correct the position of the display element 7 at any time, advantageously avoiding any bowing or attachment of watch movement parts 3 regardless of their position and orientation. It is therefore understood that the star 21 - jumper 20 - pinion 22 assembly can thus be moved either by the correction device 25 or by the control member 15 .

L'organe 27 différentiel est avantageusement formé par la couronne 23 du mécanisme 13 à plusieurs positions stables. Préférentiellement, la couronne 23 comporte ainsi en outre une denture 26 externe de soixante-seize dents afin de commander un mouvement relatif entre la couronne 23 et l'ensemble étoile 21 - sautoir 20 destiné à déplacer l'élément 7 afficheur.The differential member 27 is advantageously formed by the crown 23 of the mechanism 13 with several stable positions. Preferably, the crown 23 thus further comprises an external toothing 26 of seventy-six teeth in order to control a relative movement between the crown 23 and the star 21 - jumper 20 assembly intended to move the display element 7 .

Dans l'exemple illustré aux figures 2 à 5, le système 5 d'affichage comporte un rouage 28 de correction qui est couplé à la denture 28 externe de la couronne 23 et commandé par l'organe 10 de correction tel qu'une couronne à la figure 1 afin de modifier la position de l'élément 7 d'affichage. On comprend donc qu'en dehors des périodes de correction, la couronne 23 est maintenue immobile par le rouage 28 de correction notamment par son mobile 29 de friction et l'élément 7 afficheur est déplacé uniquement quand l'organe 15 de commande entre en contact avec l'ensemble étoile 21 - pignon 22. Le doigt 17 entre en contact tous les 1,035 tour avec l'étoile 21 en l'absence de correction. Le disque 6 est déplacé selon la durée de vingt-cinq minutes et quatorze secondes pour indiquer la prochaine marée haute.In the example shown in figures 2 to 5 , the display system 5 comprises a correction gear train 28 which is coupled to the outer toothing 28 of the crown 23 and controlled by the correction member 10 such as a crown at the figure 1 to change the position of the display element 7. It is therefore understood that outside of the correction periods, the crown 23 is held stationary by the correction gear train 28, in particular by its friction wheel set 29 and the display element 7 is moved only when the control member 15 comes into contact with the star 21 - pinion 22 assembly. The finger 17 comes into contact every 1.035 turns with the star 21 in the absence of correction. Disc 6 is moved according to the duration of twenty-five minutes and fourteen seconds to indicate the next high tide.

Pendant les périodes de correction, l'organe 10 de correction est activé de sorte à le coupler au rouage 28 de correction. Le déplacement de l'organe 10 de correction permet donc d'entraîner le rouage 28 de correction en contrant notamment le frottement de son mobile 29 de friction et ainsi commander la rotation de la couronne 23 par engrènement de sa denture 26 externe. L'étoile 21 étant bloquée par son sautoir 20, elle ne peut pas tourner. C'est donc le disque 6 solidaire de la couronne 23 qui va directement être déplacé afin de pouvoir régler l'élément 7 afficheur sur l'horaire effectif de la prochaine marée haute.During the correction periods, the correction member 10 is activated so as to couple it to the gear train 28 for correction. The movement of the correction member 10 therefore makes it possible to drive the correction gear train 28 by notably countering the friction of its friction wheel set 29 and thus controlling the rotation of the ring gear 23 by meshing of its external toothing 26. The star 21 being blocked by its jumper 20, it cannot rotate. It is therefore the disk 6 secured to the crown 23 which will be moved directly in order to be able to adjust the display element 7 to the actual time of the next high tide.

Avantageusement, le dispositif 25 permet de faire des corrections sans risque d'arcboutements ou d'accrochages des pièces en interaction, de dérégler les autres affichages ou d'influencer la marche du mouvement 3 horloger. Si, lors de la correction, l'étoile 21 rencontre le doigt 17, cela a comme simple conséquence de faire pivoter l'étoile 21 et, incidemment, de modifier la vitesse de déplacement du disque 6 pendant un court instant sans que cette variation de vitesse soit forcément perceptible par l'utilisateur.Advantageously, the device 25 makes it possible to make corrections without risk of buttressing or snagging of the interacting parts, of disturbing the other displays or of influencing the rate of the watch movement 3. If, during the correction, the star 21 encounters the finger 17, this has the simple consequence of causing the star 21 to pivot and, incidentally, of modifying the speed of movement of the disk 6 for a short time without this variation of speed is necessarily perceptible to the user.

L'invention n'est pas limitée à l'exemple illustré aux figures 1 à 5 et d'autres modes de réalisation et variantes apparaîtront clairement à l'homme du métier. Il est notamment possible de changer l'organe 27 différentiel comme par exemple par un train épicycloïdal à plusieurs satellites sans perdre les avantages de l'invention. Il va également de soi, que le mécanisme type peut être construit différemment sans pour autant changer son principe de fonctionnement en ajoutant ou en éliminant des mobiles ou autres éléments dans le train d'engrenage, différentiel ou système d'étoile. L'encombrement du système 5 d'affichage illustré est avantageusement faible, mais en fonction de l'espace disponible pour l'affichage ou pour d'autres raisons les rapports d'engrenage des mobiles peuvent également varier.The invention is not limited to the example illustrated in figures 1 to 5 and other embodiments and variations will be apparent to those skilled in the art. It is in particular possible to change the differential member 27 such as for example by an epicyclic gear train with several satellites without losing the advantages of the invention. It also goes without saying that the standard mechanism can be constructed differently without changing its operating principle by adding or eliminating mobiles or other elements in the gear train, differential or star system. The size of the illustrated display system 5 is advantageously small, but depending on the space available for the display or for other reasons, the gear ratios of the mobiles can also vary.

De même, les dentures du mécanisme 13 sont adaptées à la durée moyenne de douze heures, vingt-cinq minutes et quatorze secondes. Toutefois, les dentures du mécanisme 13 pourraient être modifiées pour effectuer un saut instantané selon une durée différente sans sortir du cadre de l'invention.Similarly, the teeth of the mechanism 13 are adapted to the average duration of twelve hours, twenty-five minutes and fourteen seconds. However, the teeth of the mechanism 13 could be modified to perform an instantaneous jump according to a different duration without departing from the scope of the invention.

Enfin, le limbe 8 pourrait être gradué selon une autre échelle comme par exemple selon vingt-quatre heures sans perdre les avantages de l'invention mais en ayant uniquement à adapter le mécanisme 13 et l'élément 7 afficheur. De plus, l'affichage des marées peut être centré au lieu d'être décentré par rapport à l'affichage horaire, et il peut se faire par une aiguille au lieu d'un disque.Finally, the limb 8 could be graduated according to another scale such as for example according to twenty-four hours without losing the advantages of the invention but only having to adapt the mechanism 13 and the display element 7. In addition, the tide display can be centered instead of off-center with respect to the time display, and it can be done by a hand instead of a disc.
