Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie et concerne une pièce d'horlogerie à affichage modulable comprenant une boîte, un mouvement logé dans la boîte, une glace fermant la boîte et un cadran disposé entre le mouvement et la glace.The present invention relates to the field of watchmaking and relates to a timepiece with modular display comprising a box, a movement housed in the box, an ice box closing and a dial disposed between the movement and the ice.

Etat de la techniqueState of the art

L'évolution de l'horlogerie, tant mécanique qu'électronique, conduit à proposer des pièces capables d'afficher un grand nombre d'informations ou pouvant offrir aux yeux du porteur, des mécanismes de plus en plus sophistiqués. Toutefois, il n'est pas toujours souhaitable que l'ensemble des informations proposées par la montre soient affichées en permanence, que ce soit par discrétion ou pour favoriser la lecture de l'heure de certaines informations particulières, qui peut être rendue difficile par la multiplication des cadrans et autres index.The evolution of watchmaking, both mechanical and electronic, leads to offer parts capable of displaying a great deal of information or offering the wearer more and more sophisticated mechanisms. However, it is not always desirable that all of the information offered by the watch be displayed permanently, either by discretion or to promote the reading of the time of certain particular information, which can be made difficult by the multiplication of dials and other indexes.

Pour répondre à ce problème, il est connu, par exemple du document EP 0 484 821 , d'avoir une pièce d'horlogerie telle que définie ci-dessus, dans laquelle les informations à afficher ne sont pas toujours visibles sur le cadran. Plus particulièrement, la montre présentée comporte des aiguilles pour afficher l'heure courante et un écran LCD, pour afficher des informations particulières, liées à une alarme. Une plaque mobile est agencée de manière à recouvrir l'affichage LCD lors du fonctionnement normal de la montre, et à s'escamoter lors de l'enclenchement de l'alarme, afin d'afficher les informations particulières.To answer this problem, it is known, for example from the document EP 0 484 821 to have a timepiece as defined above, in which the information to be displayed is not always visible on the dial. More particularly, the presented watch has needles for displaying the current time and an LCD screen for displaying particular information related to an alarm. A movable plate is arranged to cover the LCD display during normal operation of the watch, and to retract when the alarm is triggered, in order to display the particular information.

La présente invention a pour but de proposer une autre solution à ce problème, qui, en particulier, ne nécessite pas de pratiquer d'ouverture dans le cadran, mis à part celle éventuellement nécessaire pour le passage des aiguilles.The present invention aims to propose another solution to this problem, which, in particular, does not require opening in the dial, apart from that possibly necessary for the passage of needles.

Un autre but de l'invention est d'améliorer le dispositif présenté dans le document précité, en lui ajoutant un organe de commande particulièrement original.Another object of the invention is to improve the device presented in the aforementioned document, by adding a particularly original control member.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, l'invention concerne une pièce d'horlogerie à affichage modulable telle que mentionnée ci-dessus, caractérisée en ce que le cadran est positionné en regard d'au moins une zone d'affichage située entre le mouvement et le cadran et est susceptible d'occuper :

  • un premier état dans lequel, au moins dans cette zone, il ne laisse pas passer la lumière venant de l'extérieur, et
  • un deuxième état dans lequel, au moins dans cette zone, il est traversé par la lumière venant de l'extérieur de la montre jusqu'au mouvement, tout en restant positionné en regard de la zone.
More specifically, the invention relates to a timepiece with a modular display as mentioned above, characterized in that the dial is positioned facing at least one display area located between the movement and the dial. and is likely to occupy:
  • a first state in which, at least in this zone, it does not let in light coming from outside, and
  • a second state in which, at least in this zone, the light coming from the outside of the watch passes through to the movement, while remaining positioned opposite the zone.

La pièce d'horlogerie comporte en outre un organe de commande pour faire passer le cadran d'un état à l'autre.The timepiece further comprises a control member for moving the dial from one state to another.

Selon un mode de réalisation avantageux, le cadran comprend un premier verre polarisé dans une première direction et un deuxième verre polarisé dans une deuxième direction, agencés de manière à ce que, lorsque le cadran est dans son premier état, les directions de polarisation sont orientées perpendiculairement et sont parallèles dans le deuxième état.According to an advantageous embodiment, the dial comprises a first polarized lens in a first direction and a second polarized lens in a second direction, arranged so that, when the dial is in its first state, the polarization directions are oriented. perpendicularly and are parallel in the second state.

Pour ce faire, l'un des verres peut être monté sur un cadre mobile.To do this, one of the glasses can be mounted on a moving frame.

L'organe de commande est un couvercle monté mobile en référence à la boîte et évoluant entre une première et une deuxième position extrêmes, relié cinématiquement au cadre pour le faire se déplacer lorsqu'il évolue entre sa première et sa deuxième position.The control member is a lid mounted movably with reference to the box and moving between a first and a second extreme position, kinematically connected to the frame to make it move when it moves between its first and second position.

La pièce d'horlogerie selon l'invention peut également comporter l'une ou l'autre des caractéristiques suivantes :

  • le couvercle et le cadre sont reliés cinématiquement par l'intermédiaire d'une vis sans fin.
  • le couvercle et le cadre sont, en outre, reliés cinématiquement par l'intermédiaire d'un différentiel agencé de manière à démultiplier la rotation engendrée par le couvercle et transmise au cadre.
  • la première et deuxième position extrêmes du couvercle sont définies par des butées et correspondent respectivement au premier et au deuxième état du cadran.
The timepiece according to the invention may also include one or other of the following characteristics:
  • the cover and the frame are kinematically connected by means of a worm.
  • the cover and the frame are further kinematically connected via a differential arranged to increase the rotation generated by the cover and transmitted to the frame.
  • the first and second extreme positions of the lid are defined by stops and correspond respectively to the first and second state of the dial.

Brève description des dessinsBrief description of the drawings

D'autres détails de l'invention apparaîtront plus clairement à la lecture de la description qui suit, faite en référence au dessin annexé, dans lequel :

  • la figure 1 est une vue en trois dimensions d'une montre selon un mode de réalisation préféré de l'invention,
  • les figures 2 et 3 sont des vues en coupe, respectivement selon un axe AA et BB, de la montre de la figure 1, et
  • la figure 4 est une vue en gros plan du différentiel.
Other details of the invention will emerge more clearly on reading the description which follows, made with reference to the appended drawing, in which:
  • the figure 1 is a three-dimensional view of a watch according to a preferred embodiment of the invention,
  • the figures 2 and 3 are views in section, respectively along an axis AA and BB, of the watch of the figure 1 , and
  • the figure 4 is a close-up view of the differential.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

On a représenté sur la figure 1, une montre selon un mode de réalisation préféré de l'invention. De manière conventionnelle, celle-ci comporte une boîte 10, un mouvement 12, visible sur la figure 3 et logé dans la boîte, et une glace 14, fermant la boîte. Dans cette variante, le mouvement est de type mécanique ou électromécanique et entraîne, pour l'affichage du temps courant, un jeu d'aiguilles 16 disposées sous la glace, de manière à être visibles pour le porteur.We have shown on the figure 1 , a watch according to a preferred embodiment of the invention. In a conventional manner, the latter comprises a box 10, a movement 12, visible on the figure 3 and housed in the box, and an ice cream 14, closing the box. In this variant, the movement is of mechanical or electromechanical type and causes, for the display of the current time, a set of needles 16 arranged under the glass, so as to be visible to the wearer.

La montre comporte également un couvercle 18, monté articulé sur la boîte 10 selon un axe AA de manière à se superposer à la glace de la montre lorsque le couvercle est fermé. Celui-ci reçoit une glace 19 de manière à laisser les aiguilles 16 visibles lorsqu'il est fermé. La boîte est dotée de deux paires de cornes 20 pour recevoir un bracelet. De préférence, l'axe AA est perpendiculaire à l'axe du bracelet et l'articulation est disposée entre deux cornes d'une paire. Comme le montre plus particulièrement la figure 2, la boîte 10 se prolonge, au niveau de sa carrure, par une cage 22 définissant un logement. La cage est disposée entre les cornes 20 qui reçoivent l'articulation du couvercle 18. On notera que le bracelet peut être attaché à la boîte selon un axe parallèle à mais non confondu avec l'axe AA.The watch also comprises a cover 18, hingedly mounted on the box 10 along an axis AA so as to be superimposed on the watch window when the cover is closed. It receives an ice 19 so as to leave the needles 16 visible when closed. The box is provided with two pairs of horns 20 to receive a bracelet. Preferably, the axis AA is perpendicular to the axis of the bracelet and the articulation is disposed between two horns of a pair. As shown more particularly in figure 2 , the box 10 is extended at its middle, by a cage 22 defining a housing. The cage is disposed between the horns 20 which receive the hinge of the lid 18. Note that the bracelet can be attached to the box along an axis parallel to but not coincident with the axis AA.

L'articulation du couvercle sur la boîte comporte deux gonds 23 prolongeant le couvercle, chacun étant interposé entre une corne 20 et la cage 22. L'articulation est également constituée de deux tigerons 24 pivotant respectivement dans l'une et l'autre des deux parois opposées de la cage 22 perpendiculaires à l'axe AA. Deux joints 26 assurent l'étanchéité et le pivotement de chacun des tigerons 24. Ces derniers traversent la paroi de la cage 22 et sont chassés, à une première de leurs extrémités, dans chacun des gonds 22 du couvercle 18. Le cas échéant, les premiers éléments du bracelet sont fixés entre les cornes et les gonds.The hinge of the lid on the box comprises two hinges 23 extending the lid, each being interposed between a horn 20 and the cage 22. The hinge is also constituted by two tigers 24 pivoting respectively in one and the other of the two opposite walls of the cage 22 perpendicular to the axis AA. Two seals 26 ensure the sealing and the pivoting of each of the tigerons 24. These last cross the wall of the cage 22 and are driven, at a first end, in each of the hinges 22 of the cover 18. Where appropriate, the first elements of the bracelet are fixed between the horns and hinges.

Comme le montre particulièrement la figure 2, au moins l'un 24a des tigerons 24 se termine, au niveau de sa deuxième extrémité, par un carré femelle disposé à l'intérieur du logement. Comme le comprend l'homme du métier, un carré femelle 28 est une ouverture de forme carrée, disposée perpendiculairement par rapport à l'axe du tigeron, de manière à permettre un entraînement en rotation autour de cet axe.As is particularly the case figure 2 at least one 24a of the tigers 24 ends, at its second end, with a female square disposed within the housing. As understood by those skilled in the art, a female square 28 is a square-shaped opening, arranged perpendicularly to the axis of the tigeron, so as to allow a drive in rotation about this axis.

A l'intérieur du logement prend place une vis sans fin 30, au centre de laquelle est chassée une tige 32 d'axe AA formant le moyeu de la vis 30. A une première extrémité, du côté du tigeron 24a, la tige est montée pivotante sur une pierre 34 logée dans un pont 36, solidaire du logement. Comme on le comprendra plus loin, le pont est agencé de manière à servir de butée au tigeron 24, afin de limiter la course du couvercle lors de son ouverture. A sa deuxième extrémité, la tige est montée pivotante sur une pierre 38 logée dans une paroi de la cage 22. La tige 32 est donc libre en rotation par rapport au tigeron 24a.Inside the housing takes place a worm 30, in the center of which is driven a rod 32 of axis AA forming the hub of the screw 30. At a first end, on the side of the stem 24a, the rod is mounted pivoting on a stone 34 housed in a bridge 36, integral with the housing. As will be understood later, the bridge is arranged to serve as a stop to the rod 24, to limit the stroke of the lid when it opens. At its second end, the rod is pivotally mounted on a stone 38 housed in a wall of the cage 22. The rod 32 is free to rotate relative to the rod 24a.

Pour relier cinématiquement le couvercle 18 à la vis sans fin 30, un différentiel 40, illustré en détail sur la figure 4, est disposé entre le tigeron 24a solidaire en rotation du couvercle 18 et la tige 32 solidaire de la vis sans fin 30. Ce différentiel 40 a pour but de transmettre la rotation engendrée par la rotation du couvercle à la vis sans fin, en la démultipliant.To kinematically connect the cover 18 to the worm 30, a differential 40, illustrated in detail on the figure 4 , is arranged between the rod 24a integral in rotation of the cover 18 and the rod 32 integral with the worm 30. This differential 40 is intended to transmit the rotation generated by the rotation of the lid to the worm, by multiplying it .

A l'entrée de ce différentiel, un carré mâle 42 monté libre sur la tige prend place à l'intérieur du carré femelle 28 du tigeron 24a, pour être entraîné en rotation par le couvercle 18. Ce carré est solidaire d'un porte-satellite, non représenté, qui entraîne au moins deux satellites 46 autour de l'axe AA. Les satellites engrènent avec une denture intérieure 48 d'un anneau 50 solidaire de la cage. Ces satellites 46 engrènent également avec une roue solaire 52, montée libre en rotation sur la tige 32. Afin d'avoir une démultiplication plus importante, le différentiel représenté à titre d'exemple est double. Ainsi, la roue solaire 52 est solidaire d'un deuxième porte-satellite, non représenté, qui entraîne également au moins deux satellites 56 autour de l'axe AA. Les satellites 56 engrènent avec la denture intérieure de l'anneau 50. Ces satellites engrènent également avec une deuxième roue solaire 58, solidaire de la tige 32. Cette construction permet avantageusement d'avoir un rapport d'engrenages important, avec un mécanisme occupant peu de place. Il serait possible de n'avoir qu'un différentiel simple en utilisant la roue solaire 52 comme sortie du différentiel. Dans ce cas, celle-ci est solidaire de la tige.At the entrance of this differential, a male square 42 mounted free on the rod takes place inside the female square 28 of the rod 24a, to be rotated by the cover 18. This square is secured to a carrier satellite, not shown, which drives at least two satellites 46 about the axis AA. The satellites meshing with an internal toothing 48 of a ring 50 integral with the cage. These satellites 46 also mesh with a sun gear 52, mounted free to rotate on the rod 32. In order to have a larger gear, the differential shown by way of example is double. Thus, the sun wheel 52 is secured to a second planet carrier, not shown, which also drives at least two satellites 56 about the axis AA. The satellites 56 meshes with the internal toothing of the ring 50. These satellites also mesh with a second sun gear 58, integral with the rod 32. This construction advantageously allows to have a gear ratio important, with a mechanism occupying little square. It would be possible to have only a single differential using the sun gear 52 as the output of the differential. In this case, it is secured to the rod.

On notera également que le diamètre de la tige 32 peut avantageusement ne pas être constant. Plus précisément, pour avoir une liaison mécaniquement solide entre la tige et la vis sans fin, la tige peut avoir un premier diamètre relativement important au niveau de l'interface avec la vis, tandis que, pour avoir des roues solaires 52 et 58 du différentiel 40 de petit diamètre, la tige 32 présente un deuxième diamètre inférieur au premier, au niveau du différentiel 40.It will also be noted that the diameter of the rod 32 may advantageously not be constant. More specifically, to have a mechanically strong connection between the rod and the worm, the rod may have a relatively large first diameter at the interface with the screw, while for having the differential wheels 52 and 58 40 of small diameter, the rod 32 has a second diameter smaller than the first, at the differential 40.

Sous la glace 14, la montre comporte un cadran 60 disposé sous les aiguilles 16. Selon un mode de réalisation préféré de l'invention, le cadran est formé de deux disques 62, 64 superposés et réalisés en verres polarisés percés en leur centre de manière à laisser passer les aiguilles 16.Under the glass 14, the watch has a dial 60 arranged under the needles 16. According to a preferred embodiment of the invention, the dial is formed of two disks 62, 64 superimposed and made of polarized lenses pierced at their center so to let the needles pass 16.

Un premier verre 62 est fixé, par exemple par clipsage, collage, soudage, vissage ou en étant maintenu par une bague de fixation, sur un réhaut 66 que comporte la boîte.A first glass 62 is fixed, for example by clipping, gluing, welding, screwing or being held by a fixing ring, on a flange 66 that includes the box.

Un deuxième verre 64 est fixé sur un cadre circulaire 68 monté mobile en rotation autour du centre du cadran. Ce cadre est disposé entre le réhaut et un cercle d'encageage 70, qui comprennent chacun, en vis-à-vis, un chemin de bille 72 entre lesquels le cadre pivote. Le deuxième verre 64 est situé suffisamment loin du mouvement pour permettre de disposer des petits cadrans 74 pour afficher différentes informations, comme une petite seconde, une réserve de marche, une phase de lune etc.... Le cadre 68 comprend, sur son pourtour un extérieur, une denture 76 en prise avec la vis sans fin 30. Ainsi, le pivotement de la vis 30 met en rotation le cadre 68, et donc le deuxième verre 64.A second glass 64 is fixed on a circular frame 68 rotatably mounted around the center of the dial. This frame is disposed between the flange and a casing ring 70, which each comprise, in facing relation, a ball path 72 between which the frame pivots. The second glass 64 is located far enough from the movement to allow small dials 74 to be displayed to display different information, such as a small second, a power reserve, a moon phase, etc. The frame 68 comprises, on its periphery an outside, a toothing 76 in engagement with the worm 30. Thus, the pivoting of the screw 30 rotates the frame 68, and therefore the second glass 64.

Plus particulièrement, la démultiplication réalisée par le différentiel 40, d'une part, le rapport entre les dentures de la vis sans fin 30 et du cadre 68, d'autre part, sont déterminés de manière à ce que, lorsque le couvercle 18 passe d'une première position dans laquelle il est fermé sur la glace de la montre, à une deuxième position dans laquelle il est ouvert et mis en butée sur le pont 36 par l'intermédiaire du tigeron 24a, le deuxième verre 64 tourne d'un angle prédéfini, dont la valeur peut être, par exemple, de 90°. En outre, les deux verres 62 et 64 sont agencés de manière à ce que, lorsque le couvercle est dans sa première position, les directions de polarisation des deux verres sont parallèles et, lorsque le couvercle est dans sa deuxième direction, elles sont perpendiculaires.More particularly, the reduction achieved by the differential 40, on the one hand, the ratio between the teeth of the worm 30 and the frame 68, on the other hand, are determined so that, when the lid 18 passes from a first position in which it is closed on the ice of the watch, to a second position in which it is open and abutted on the bridge 36 via the shank 24a, the second lens 64 turns of a predefined angle, whose value can be, for example, 90 °. In addition, the two glasses 62 and 64 are arranged so that, when the lid is in its first position, the polarization directions of the two glasses are parallel and, when the lid is in its second direction, they are perpendicular.

Le couvercle sert donc d'organe de commande pour modifier l'état du cadran. Plus particulièrement, lorsque le couvercle 18 est fermé, les deux verres 62 et 64 formant le cadran ne laissent pas passer la lumière et seules les aiguilles 16 sont visibles, derrière la glace 19 du couvercle et celle 14 de la montre, sur un fond noir constitué par le cadran 60. Lorsque le couvercle 18 est ouvert, les deux verres 62 et 64 formant le cadran 60 laissent passer au moins une partie de la lumière de manière à ce que les indications particulières affichées derrière le cadran ou d'éventuelles ouvertures laissant apparaître le mouvement, soient visibles au travers du cadran.The cover therefore serves as a control member to change the state of the dial. More particularly, when the lid 18 is closed, the two glasses 62 and 64 forming the dial do not let light and only the needles 16 are visible behind the glass 19 of the lid and 14 of the watch, on a black background constituted by the dial 60. When the lid 18 is open, the two glasses 62 and 64 forming the dial 60 pass at least a portion of the light so that the particular indications displayed behind the dial or possible openings leaving appear movement, be visible through the dial.

Bien que préféré, le mode de réalisation ci-dessus n'est qu'un exemple particulier illustrant l'invention. L'organe de commande pourrait être réalisé plus simplement, par exemple en utilisant une lunette tournante ou un verrou monté mobile dans la carrure de la boîte. En outre, la rotation de la vis 30 peut être amenée par un train d'engrenages en un endroit quelconque du mouvement, par exemple pour actionner un verre monté mobile au niveau d'un petit cadran, à l'instar de ce qui a été décrit ci-dessus pour le cadran principal. Le mouvement de rotation engendré par le couvercle et transmis au cadre mobile peut être démultiplié au niveau du train d'engrenage, sans qu'un différentiel soit nécessaire.Although preferred, the above embodiment is only a particular example illustrating the invention. The control member could be made more simply, for example using a rotating bezel or a latch mounted movably in the middle of the box. In addition, the rotation of the screw 30 can be brought by a gear train at any point of the movement, for example to actuate a movably mounted glass at a small dial, like what has been described above for the main dial. The rotational movement generated by the cover and transmitted to the moving frame can be multiplied at the gear, without a differential is required.

Par ailleurs, il est possible d'obtenir par différentes manière un cadran susceptible d'occuper

  • un premier état dans lequel, au moins dans une zone visible à travers la glace de la montre et normalement utilisée pour afficher une information, il ne laisse pas passer la lumière venant de l'extérieur jusqu'au mouvement, et
  • un deuxième état dans lequel, au moins dans cette zone, il est traversé par la lumière venant de l'extérieur de la montre jusqu'au mouvement, tout en restant positionné en regard de la zone.
Moreover, it is possible to obtain in different ways a dial likely to occupy
  • a first state in which, at least in an area visible through the ice of the watch and normally used to display information, it does not let the light coming from the outside to the movement, and
  • a second state in which, at least in this zone, the light coming from the outside of the watch passes through to the movement, while remaining positioned opposite the zone.

En effet, le but de l'invention est bien de masquer ou de rendre visible une information affichée sous le cadran, un décor ou une partie du mouvement, située sur sa face supérieure, c'est-à-dire du côté de la glace, mais sans que le cadran s'ouvre ou s'escamote. Le mouvement reste en permanence protégé par le cadran.Indeed, the purpose of the invention is to hide or make visible information displayed under the dial, a decor or part of the movement, located on its upper face, that is to say on the side of the ice but without the dial opening or retracting. The movement remains permanently protected by the dial.

Ainsi, le cadran pourrait également être constitué de deux prismes, l'un au moins étant susceptible de se déplacer perpendiculairement par rapport au plan du cadran. Le prisme supérieur, c'est-à-dire celui situé du côté de la glace, présente une face colorée qui réfléchit la lumière lorsque le cadran est dans son premier état et que les deux prismes sont distants l'un de l'autre. Lorsque le cadran est dans son deuxième état, le premier cadran est amené au contact du deuxième prisme et s'emboîte avec lui. La lumière incidente traverse alors les deux prismes, sans être réfléchie sur la face colorée, ce qui permet de laisser passer la lumière jusqu'au mouvement ou à la zone d'affichage.Thus, the dial could also consist of two prisms, at least one being able to move perpendicular to the plane of the dial. The upper prism, that is to say the one located on the side of the ice, has a colored face that reflects the light when the dial is in its first state and the two prisms are distant from each other. When the dial is in its second state, the first dial is brought into contact with the second prism and engages with it. The incident light then passes through the two prisms, without being reflected on the colored face, allowing the light to pass to the movement or the display area.

Il est aisé pour l'homme du métier de monter un prisme mobile, guidé en plusieurs points et mis en contrainte par un ressort pour éviter tout mouvement intempestif. Une came actionnée par un organe de commande pousse le prisme en contraignant le ressort, de manière à l'amener au contact de l'autre prisme. L'organe de commande peut être un couvercle ou un des autres organes cités précédemment.It is easy for a person skilled in the art to mount a mobile prism, guided at several points and constrained by a spring to prevent any inadvertent movement. A cam actuated by a control member pushes the prism by forcing the spring, so as to bring it into contact with the other prism. The control member may be a cover or one of the other organs mentioned above.

On pourrait également imaginer que le premier et le deuxième verres présentent chacun une alternance régulière de portions identiques de deux types, les portions du premier type étant polarisées dans une première direction et les portions du deuxième type étant polarisées dans une deuxième direction. L'un des verres est disposé dans un cadre monté mobile en translation ou en rotation. Dans le premier cas, les portions sont des bandes, tandis que dans le deuxième cas, ce sont des secteurs. Dans le premier cas, la translation du verre mobile peut être obtenue de différentes manières, notamment par l'intermédiaire d'un couvercle qui peut être également mobile en translation, à l'instar du couvercle d'un plumier. Le couvercle pourrait également pivoter, comme dans le mode de réalisation décrit précédemment, le mouvement de translation du cadre étant obtenu par l'intermédiaire d'une came, un organe ressort assurant le retour du cadre à sa position initiale. Dans le deuxième cas, la rotation du verre peut être obtenue de manière similaire à ce qui a été mentionné ci-dessus.One could also imagine that the first and second glasses each have a regular alternation of identical portions of two types, the portions of the first type being polarized in a first direction and the portions of the second type being polarized in a second direction. One of the glasses is arranged in a frame mounted to move in translation or in rotation. In the first case, the portions are bands, while in the second case they are sectors. In the first case, the translation of the movable glass can be obtained in various ways, in particular by means of a lid which can be also mobile in translation, like the lid of a pen. The lid could also pivot, as in the embodiment described above, the translational movement of the frame being obtained via a cam, a spring member ensuring the return of the frame to its initial position. In the second case, the rotation of the glass can be obtained in a manner similar to that mentioned above.

Le cadre mobile est agencé de manière à se déplacer entre

  • une première position dans laquelle les portions du premier type de chacun des verres sont disposées en quinconce (il en est donc de même pour les portions du deuxième type) de sorte que la lumière traverse les deux verres, et
  • une deuxième position dans laquelle les portions du premier type d'un premier verre sont superposées aux portions du deuxième type de l'autre verre (et vice versa), les directions de polarisation desdites portions étant orientées de manière à ce que, dans cette position, la lumière ne traverse pas les deux verres.
The mobile frame is arranged to move between
  • a first position in which the portions of the first type of each of the glasses are arranged in staggered rows (so it is the same for the portions of the second type) so that the light passes through the two glasses, and
  • a second position in which the portions of the first type of a first glass are superimposed on the portions of the second type of the other glass (and vice versa), the polarization directions of said portions being oriented so that in this position , the light does not cross the two glasses.

Bien entendu, dans le cas d'un mouvement en translation, le verre mobile doit comporter une ouverture en conséquence pour le passage des aiguilles.Of course, in the case of a translational movement, the movable glass must have an aperture accordingly for the passage of the needles.

Le cadran peut également comporter une cellule de type LCD connue de l'homme du métier, comportant une couche de cristal liquide disposé entre deux électrodes et entre deux polariseurs orientés à 90°. Ainsi, lorsque la cellule n'est pas sous tension, la lumière incidente traverse le premier polariseur, subit une rotation de 90° à travers la couche de cristal liquide, traverse le deuxième polariseur avant d'être réfléchie et de ressortir de la cellule par le chemin inverse. Lorsque la cellule est sous tension, les cristaux liquides s'alignent dans le champ électrique. La lumière incidente polarisée par le premier polariseur ne subit pas de rotation en traversant les cristaux liquides et ne peut donc pas traverser le deuxième polariseur. La cellule apparaît donc noire.The dial may also include an LCD type cell known to those skilled in the art, comprising a liquid crystal layer disposed between two electrodes and between two polarisers oriented at 90 °. Thus, when the cell is not energized, the incident light passes through the first polarizer, undergoes a 90 ° rotation through the liquid crystal layer, passes through the second polarizer before being reflected and out of the cell by the opposite way. When the cell is energized, the liquid crystals line up in the electric field. The incident light polarized by the first polarizer is not rotated through the liquid crystal and therefore can not pass through the second polarizer. The cell appears black.

Naturellement, la pièce d'horlogerie doit, dans ce mode de réalisation, comporter une source d'énergie reliée à la cellule. L'organe de commande peut n'être qu'un simple bouton. De manière avantageuse, la cellule peut être dimensionnée à l'envi de manière à n'occuper qu'une zone déterminée du cadran.Naturally, the timepiece must, in this embodiment, include a power source connected to the cell. The controller may be just a button. Advantageously, the cell can be sized to occupy a specific area of the dial.

Ainsi est proposée une pièce d'horlogerie proposant un affichage modulable, permettant d'afficher uniquement et très lisiblement l'heure courante ou, de manière supplémentaire, d'autres fonctions, un décor ou une partie du mouvement, sans nécessiter de pratiquer d'ouverture dans le cadran.Thus is proposed a timepiece with a modular display, to display only and very legibly the current time or, in addition, other functions, a decor or part of the movement, without the need to practice. opening in the dial.

Selon un deuxième aspect de l'invention, visant à améliorer le dispositif décrit dans le document EP 0 484 821 et à l'adapter à une montre ne comportant pas de source d'énergie électrique, l'homme du métier peut prévoir que la montre comporte un cadran de type conventionnel, disposé entre le mouvement et la glace, et percé d'une ouverture. Un cache dimensionné de manière à pouvoir recouvrir l'ouverture est monté mobile sous le cadran, entre une première position dans laquelle il obture ladite ouverture et une deuxième position dans laquelle il la laisse libre. Un couvercle similaire à celui décrit dans le premier mode de réalisation ci-dessus est disposé sur la montre et entraîne un système de transmission de l'énergie, reliant cinématiquement le couvercle au cache, à l'instar du cadre mobile ci-dessus. Ainsi, lorsque le couvercle évolue entre sa première et sa deuxième positions extrêmes, il entraîne le cache au lieu d'entraîner le cadre mobile. De la sorte, lorsque le couvercle est fermé, l'ouverture est obturée par le cache et un cadran non ouvert est visible à travers la glace du couvercle. Lorsque le couvercle est ouvert, l'ouverture est libre et laisse apparaître un affichage d'une fonction supplémentaire, un décor ou une partie du mouvement.According to a second aspect of the invention, to improve the device described in the document EP 0 484 821 and to adapt it to a watch that does not include a source of electrical energy, the person skilled in the art can provide that the watch comprises a conventional type dial disposed between the movement and the ice, and pierced with an opening. A cover sized so as to cover the opening is mounted movably under the dial, between a first position in which it closes said opening and a second position in which it leaves it free. A lid similar to that described in the first embodiment above is disposed on the watch and drives a power transmission system, kinematically connecting the cover to the cache, like the movable frame above. Thus, when the lid moves between its first and second extreme positions, it drives the cache instead of driving the mobile frame. In this way, when the lid is closed, the opening is closed by the cover and an unopened dial is visible through the cover glass. When the lid is open, the opening is free and reveals a display of an additional function, a decor or part of the movement.
