Definitions
- the subject of the present invention is improvements to display devices of the date type used on devices intended to indicate time such as, in particular, watches.
- these devices include a window provided in the watch face, through which the user can observe the signs to be displayed, arranged on a disc driven in rotation by the movement of the watch.
- the watch shown in FIG. 1 is a watch of a known type, in which a disc 1, bearing on its upper side the signs to be displayed, is rotated by the movement of the watch and scrolls during its rotation opposite a window 5 provided in the dial 3. It is clear that, in this watch, all of the the image located in the portion a of the disc is hidden from view by the observer located at 0 by the corner 7 of the window. In addition, as can also be seen in FIG. 1, the part of the image visible through the window 5 is not, beyond a given incidence of the light rays, fully illuminated. Indeed, we can easily see that part b of the image of the disc protected by the edge 8 of the window is located in a half-light zone.
- the object of the present invention is to remedy these drawbacks by proposing a display system which is completely free from the lighting and masking faults mentioned above and which allows the user to read from an observation angle. practically any.
- the subject of the invention is a watch or the like equipped with a date-type display device, in which the signs to be displayed are carried by a mobile support and are perceived by an observer through a window. formed in a part of the watch, this watch being characterized in that a bundle of coherent optical fibers is engaged in said window in such a way that one end of said bundle is disposed near the mobile support, while its other end is flush a visible face of an element of the watch, distinct or not from the part in which said window is formed.
- This visible face will constitute the reading plane of the display system and it may be constituted by the upper face of the watch face, the window being provided in this case in said face to the right of the movable support and the bundle of optical fibers flush the upper face of the dial.
- the reading plane could also consist of the upper face of the watch crystal, the bundle of optical fibers extending through a window provided in the dial directly above the mobile support up to the upper face of the ice.
- the reading plane may finally be constituted by an upper face of the watch case, the window being in this case formed in the body of the case directly above the mobile support, up to an upper face of the case, and said beam of fibers being housed in this window so as to be flush with said upper face.
- an optical bridge consisting of a low viscosity liquid will be interposed between the support of the signs to be displayed and the contiguous end of the bundle of optical fibers.
- the image of the displayed sign is thus improved in clarity by avoiding multiple parasitic reflections at the level of the surfaces of the fiber bundles and of the observation surface.
- the risk of scratches on the adjacent surfaces is avoided during the movement of the support of the signs to be displayed, since they can thus be moved away sufficiently without risking harming the sharpness.
- the lubrication ensured by the liquid will prevent the formation of scratches.
- the bundle of fibers is mounted "floating" on the film of liquid deposited on the disc, its lateral retention being ensured by the internal walls of the window. It is noted that in addition to its simplicity, this embodiment has the advantage of ensuring a constant spacing between the bundle of fibers and the disc. This results in practically total elimination, on the one hand, of the risks of scratches and, on the other hand, of irregularities in the image observed due to the differences in distance between the disc and the bundle of fibers.
- the liquid may rest on the upper face of the support of the signs to be displayed or be housed in a bowl of said support.
- This liquid could simply be an oil of the type used in watchmaking for the lubrication of small movements.
- the case 20 is closed at its upper part by a crystal 22. It supports a dial 24 pierced in its center with an orifice 26 intended for the passage of two axes 28 and 30, carrying respectively the hands 32 and 34 of the watch. It is also pierced with a circular window 36, in which is fixed, for example by gluing, a bundle 38 of coherent optical fibers.
- the upper end 40 of the beam 38 is arranged in the upper plane of the dial 24 and its lower end 42 is located a short distance from the surface of a rotating disc 44 carrying the signs to be displayed, dates for example.
- the signs will appear, like the hour indications, not as being located at the bottom of the bowl, but on the surface of the dial, on which they will stand out clearly, as can be seen in FIG. 3 ( see also figure 8).
- the window 36 ′ in which the bundle 38 of optical fibers is housed is formed in a lateral part of the case 20, directly above the disc 44, and the upper end of the bundle 38 is flush with the upper face of the housing, which then constitutes the reading plane.
- the window 36 in which the bundle of optical fibers 38 is engaged is formed in the dial 34, as in the case of the embodiment of FIG. 2, but its upper part is engaged in a slot 46 formed in the crystal 22 of the watch, on the outer surface of which is flush with the upper end of said beam.
- Figures 6 and 7 illustrate two alternative embodiments of the watch according to Figure 2, in which the bundle 38 of optical fibers is always housed in a window 36 of the dial 24, but where an optical bridge, intended to ensure the quality of the reading of the displayed signs is provided between the end of the beam 38 and the disc 44.
- the bundle 38 is integral with the dial 24 and the face of the rotating disc 44 facing the lower end of said bundle is coated with a liquid 48 with a low viscosity index, for example an oil for movement timepieces of the type marketed by the HOBIUS Company under reference No. 9027.
- the oil film is in contact with the adjacent end of the beam 38 and thus provides an optical bridge between the fibers and the disc 44. It removes or also reduces the risk of scratches due to accidental contact of the fiber bundle and the dial.
- the liquid 48 is placed in an annular bowl of the disc 44, in which the lower end of the bundle 38 of optical fibers rests, and this bundle, instead of being rigidly secured to the dial 24 is mounted floating in the window 36, the side walls of which simply serve to guide and maintain the bundle 38.
- the bundle 38 of fibers can move under the stress of the disc 44 while maintaining a constant distance from that -this. This avoids any risk of scratches on the disc and / or the end face of the fiber bundle.
- the invention therefore provides improvements which are simple and easy to implement in watches or the like equipped with a mobile display system of the date type, with a view to improving the observation of the indications carried by the display system.

Description
La présente invention a pour objet des perfectionnements aux dispositifs d'affichage du type dateur utilisés sur les appareils destinas à indiquer le temps tels que, notamment, des montres.The subject of the present invention is improvements to display devices of the date type used on devices intended to indicate time such as, in particular, watches.
D'ordinaire, ces dispositifs comprennent une fenêtre prévue dans le cadran de la montre, au travers de laquelle l'utilisateur peut observer les signes à afficher, disposés sur un disque entraîné en rotation par le mouvement de la montre.Usually, these devices include a window provided in the watch face, through which the user can observe the signs to be displayed, arranged on a disc driven in rotation by the movement of the watch.
Un inconvénient majeur inhérent à ce type d'affichage réside toutefois dans la difficulté de percevoir les signes affichés, dès lors que l'observateur n'est pas rigoureusement dans l'axe de la fenêtre.A major drawback inherent in this type of display, however, lies in the difficulty of perceiving the signs displayed, since the observer is not strictly in the axis of the window.
Cet inconvénient sera explicité ci-après, en référence à la figure 1 des dessins annexés, dont les autres dessins illustrent des formes de mise en oeuvre de l'invention, auxquelles on se référera dans la suite de la présente description. Sur ces dessins :
- La figure 1 est une coupe axiale partielle d'une montre d'un type connu à système dateur ;
- La figure 2 est une coupe analogue d'une montre conforme à l'invention
- La figure 3 est une coupe suivant la ligne III-III de la figure 2 ;
- Les figures 4 et 5 sont des coupes partielles analogues à celles des figures 1 et 2, d'autres formes de réalisation de l'invention ;
- Les figures 6 et 7 illustrent des variantes de réalisation de la montre de la figure 2 ;
- La figure 8 est une coupe selon la ligne VIII-VIII de la figure 7.
- Figure 1 is a partial axial section of a watch of a known type with date system;
- Figure 2 is a similar section of a watch according to the invention
- Figure 3 is a section along line III-III of Figure 2;
- Figures 4 and 5 are partial sections similar to those of Figures 1 and 2, other embodiments of the invention;
- Figures 6 and 7 illustrate alternative embodiments of the watch of Figure 2;
- Figure 8 is a section along line VIII-VIII of Figure 7.
La montre représentée sur la figure 1 est une montre d'un type connu, dans laquelle un disque 1, portant sur sa face supérieure les signes à afficher, est entraîné en rotation par le mouvement de la montre et défile au cours de sa rotation en regard d'une fenêtre 5 prévue dans le cadran 3. Il est clair que, dans cette montre, toute la partie de l'image située dans la portion a du disque se trouve dissimulée à la vue de l'observateur situé en 0 par le coin 7 de la fenêtre. De plus, comme on le voit également sur la figure 1, la partie de l'image visible au travers de la fenêtre 5 n'est pas, au-delà d'une incidence donnée des rayons lumineux, éclairée dans sa totalité. En effet, on voit aisément que la partie b de l'image du disque protégée par le bord 8 de la fenêtre est située dans une zone de pénombre.The watch shown in FIG. 1 is a watch of a known type, in which a disc 1, bearing on its upper side the signs to be displayed, is rotated by the movement of the watch and scrolls during its rotation opposite a
On a certes proposé, pour remédier partiellement à ces deux inconvénients, de diminuer l'épaisseur apparente du cadran en réalisant des chanfreins sur les bords internes de la fenêtre. Cependant, cette disposition n'est pas totalement satisfaisante, d'autant que, pour des raisons d'ordre mécanique (voilage du disque rotatif), on est obligé de prévoir un espace relativement important entre cadran et disque rotatif.It has certainly been proposed, to partially remedy these two drawbacks, to reduce the apparent thickness of the dial by making chamfers on the internal edges of the window. However, this arrangement is not entirely satisfactory, especially since, for mechanical reasons (warping of the rotating disc), it is necessary to provide a relatively large space between the dial and the rotating disc.
On a également proposé, afin d'améliorer la facilité de lecture, de grossir les dimensions des signes affichés au moyen d'une loupe fixée sur la glace de la montre ou faisant partie intégrante de celle-ci. Outre le fait que cette solution ne remédie en rien aux défauts de masquage et de pénombre précédemment mentionnés, elle diminue encore l'angle sous lequel il est possible à l'utilisateur d'effectuer sa lecture.It has also been proposed, in order to improve the ease of reading, to enlarge the dimensions of the signs displayed by means of a magnifying glass fixed on the crystal of the watch or forming an integral part thereof. In addition to the fact that this solution does not remedy the aforementioned masking and half-light faults, it also reduces the angle under which it is possible for the user to read.
La présente invention a pour but de remédier à ces inconvénients en proposant un système d'affichage totalement exempt des défauts d'éclairement et de masquage mentionnés ci-dessus et qui permette à l'utilisateur d'effectuer sa lecture sous un angle d'observation pratiquement quelconque.The object of the present invention is to remedy these drawbacks by proposing a display system which is completely free from the lighting and masking faults mentioned above and which allows the user to read from an observation angle. practically any.
A cet effet, l'invention a pour objet une montre ou similaire équipée d'un dispositif d'affichage du type dateur, dans lequel les signes à afficher sont portés par un support mobile et sont perçus par un observateur à travers une fenêtre ménagée dans une partie de la montre, cette montre étant caractérisée en ce qu'un faisceau de fibres optiques cohérentes est engagé dans ladite fenêtre de façon telle qu'une extrémité dudit faisceau soit disposée à proximité du support mobile, tandis que son autre extrémité affleure une face visible d'un élément de la montre, distinct ou non de la partie dans laquelle est ménagée ladite fenêtre.To this end, the subject of the invention is a watch or the like equipped with a date-type display device, in which the signs to be displayed are carried by a mobile support and are perceived by an observer through a window. formed in a part of the watch, this watch being characterized in that a bundle of coherent optical fibers is engaged in said window in such a way that one end of said bundle is disposed near the mobile support, while its other end is flush a visible face of an element of the watch, distinct or not from the part in which said window is formed.
Cette face visible constituera le plan de lecture du système d'affichage et elle pourra être constituée par la face supérieure du cadran de la montre, la fenêtre étant ménagée dans ce cas dans ledit cadran au droit du support mobile et le faisceau de fibres optiques affleurant la face supérieure du cadran.This visible face will constitute the reading plane of the display system and it may be constituted by the upper face of the watch face, the window being provided in this case in said face to the right of the movable support and the bundle of optical fibers flush the upper face of the dial.
Le plan de lecture pourra aussi être constitué par la face suppérieure de la glace de la montre, le faisceau de fibres optiques s'étendant à travers une fenêtre ménagée dans le cadran à l'aplomb du support mobile jusqu'à la face supérieure de la glace.The reading plane could also consist of the upper face of the watch crystal, the bundle of optical fibers extending through a window provided in the dial directly above the mobile support up to the upper face of the ice.
Le plan de lecture pourra enfin 8tre constitué par une face supérieure du bottier de montre, la fenêtre étant dans ce cas ménagée dans le corps du boîtier à l'aplomb du support mobile, jusqu'à une face supérieure du boîtier, et ledit faisceau de fibres étant logé dans cette fenêtre de manière à affleurer ladite face supérieure.The reading plane may finally be constituted by an upper face of the watch case, the window being in this case formed in the body of the case directly above the mobile support, up to an upper face of the case, and said beam of fibers being housed in this window so as to be flush with said upper face.
Avantageusement, un pont optique constitué d'un liquide à faible viscosité sera interposé entre le support des signes à afficher et l'extrémité contiguë du faisceau de fibres optiques. D'une part, on améliore ainsi la netteté de l'image du signe affiché en évitant de multiples réflexions parasites au niveau des surfaces des faisceaux de fibres et de la surface d'observation. D'autre part, on évite les risques de rayures des surfaces adjacentes,au cours du déplacement du support des signes à afficher, puisqu'on peut ainsi les éloigner suffisamment sans risquer de nuire à la netteté. De plus, dans le cas où ces deux surfaces viendraient en contact, la lubrification assurée par le liquide évitera la formation de rayures.Advantageously, an optical bridge consisting of a low viscosity liquid will be interposed between the support of the signs to be displayed and the contiguous end of the bundle of optical fibers. On the one hand, the image of the displayed sign is thus improved in clarity by avoiding multiple parasitic reflections at the level of the surfaces of the fiber bundles and of the observation surface. On the other hand, the risk of scratches on the adjacent surfaces is avoided during the movement of the support of the signs to be displayed, since they can thus be moved away sufficiently without risking harming the sharpness. In addition, in the event that these two surfaces come into contact, the lubrication ensured by the liquid will prevent the formation of scratches.
Dans une variante particulièrement intéressante de l'invention le faisceau de fibres est monté "flottant" sur le film de liquide déposé sur le disque, son maintien latéral étant assuré par les parois internes de la fenêtre. On constate qu'outre sa simplicité, cette forme de réalisation présente l'avantage d'assurer un écartement constant entre le faisceau de fibres et le disque. Il en résulte une élimination pratiquement totale,d'une part,des risques de rayures et,d'autre, part,des irrégularités de l'image observée dues aux différences d'éloignement du disque avec le faisceau de fibres.In a particularly advantageous variant of the invention, the bundle of fibers is mounted "floating" on the film of liquid deposited on the disc, its lateral retention being ensured by the internal walls of the window. It is noted that in addition to its simplicity, this embodiment has the advantage of ensuring a constant spacing between the bundle of fibers and the disc. This results in practically total elimination, on the one hand, of the risks of scratches and, on the other hand, of irregularities in the image observed due to the differences in distance between the disc and the bundle of fibers.
Le liquide pourra reposer sur la face supérieure du support des signes à afficher ou être logé dans une cuvette dudit support.The liquid may rest on the upper face of the support of the signs to be displayed or be housed in a bowl of said support.
Ce liquide pourra être simplement une huile du type de celles utilisées en horlogerie pour la lubrification des petits mouvements.This liquid could simply be an oil of the type used in watchmaking for the lubrication of small movements.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée qui va suivre, dans laquelle on se réfèrera aux figuros2 à 8 des dessins annexés.Other characteristics and advantages of the invention will appear in the detailed description which follows, in which reference will be made to figures 2 to 8 of the appended drawings.
Dans la montre des figures 2 et 3, le boitier 20 est fermé à sa partie supérieure par une glace 22. Il supporte un cadran 24 percé en son centre d'un orifice 26 destiné au passage de deux axes 28 et 30,portant respectivement les aiguilles 32 et 34 de la montre. Il est percé également d'une fenêtre circulaire 36, dans laquelle est fixé, par exemple par collage, un faisceau 38 de fibres optiques cohérentes. L'extrémité supérieure 40 du faisceau 38 est disposée dans le plan supérieur du cadran 24 et son extrémité inférieure 42 est située à courte distance de la surface d'un disque rotatif 44 portant les signes à afficher, des dates par exemple. Ainsi, pour l'utilisateur, les signes apparaîtront, comme les indications des heures, non pas comme étant situés au fond de la cuvette, mais à la surface du cadran, sur laquelle ils ressortiront clairement, comme on le voit sur la figure 3 (voir également figure 8).In the watch of FIGS. 2 and 3, the
Dans les formes de réalisation des figures 4 à 7, les organes décrits en relation avec la figure 2 conscrvent les mêmes chiffres de référence.In the embodiments of Figures 4 to 7, the members described in connection with Figure 2 conscreate the same reference numbers.
Dans la montre de la figure 4, la fenêtre 36' dans laquelle est logé le faisceau 38 de fibres optiques est ménagée dans une partie latérale du bottier 20, à l'aplomb du disque 44, et l'extrémité supérieure du faisceau 38 affleure la face supérieure du boîtier, qui constitue alors le plan de lecture.In the watch of FIG. 4, the
Sur la figure 5, la fenêtre 36 dans laquelle est engagé le faisceau de fibres optiques 38 est ménagée dans le cadran 34, comme dans le cas de la forme de réalisation de la figure 2, mais sa partie supérieure est engagée dans une lumière 46 ménagée dans la glace 22 de la montre, à la surface externe de laquelle affleure l'extrémité supérieure dudit faisceau.In FIG. 5, the
Les figures 6 et 7 illustrent deux variantes de réalisation de la montre selon la figure 2, dans lesquelles le faisceau 38 de fibres optiques est toujours logé dans une fenêtre 36 du cadran 24, mais où un pont optique,destiné à assurer la qualité de la lecture des signes affichés est prévu entre l'extrémité du faisceau 38 et le disque 44.Figures 6 and 7 illustrate two alternative embodiments of the watch according to Figure 2, in which the
Dans le cas de la figure 6, le faisceau 38 est solidaire du cadran 24 et la face du disque rotatif 44 tournée vers l'extrémité inférieure dudit faisceau est enduite d'un liquide 48 à faible indice de viscosité, par exemple une huile pour mouvement d'horlogerie du type commercialisé par la Société HOBIUS sous la référence N° 9027. Le film d'huile est en contact avec l'extrémité adjacente du faisceau 38 et assure ainsi un pont optique entre les fibres et le disque 44. Il supprime ou réduit en outre les risques de rayures consécutifs à un contact accidentel du faisceau de fibres et du cadran.In the case of FIG. 6, the
Dans la variante de la figure 7, le liquide 48 est disposé dans une cuvette annulaire du disque 44, dans laquelle repose l'extrémité inférieure du faisceau 38 de fibres optiques, et ce faisceau, au lieu d'être rigidement solidaire du cadran 24 est monté flottant dans la fenêtre 36, dont les parois latérales servent simplement à guider et à maintenir lc faisceau 38. Dans ce cas, le faisceau 38 de fibres peut se déplacer sous la sollicitation du disque 44 en maintenant un écart constant avec celui-ci. On évite ainsi tout risque de rayures du disque et/ou de la face d'extrémité du faisceau de fibres.In the variant of FIG. 7, the
L'invention apporte donc des perfectionnements simples et faciles à mettre en oeuvre aux montres ou similaires équipées d'un système d'affichage mobile du type dateur, en vue d'améliorer l'observation des indications portées par le système d'affichage.The invention therefore provides improvements which are simple and easy to implement in watches or the like equipped with a mobile display system of the date type, with a view to improving the observation of the indications carried by the display system.
