Definitions

  • the present invention relates to a wristwatch comprising a dial with luminous index. More specifically, the invention relates to a wristwatch for reading information located on the dial in the dark as well as in daylight.
  • Timepieces of the wristwatch type allowing their wearer to read the time in the dark are already known.
  • these wristwatches include a dial, typically brass, in which are formed recesses that materialize the hour markers eg full hours. These recesses are then filled by means of a syringe dispensing a phosphorescent material capable of restoring at night the light energy that phosphorescent material has stored during the day.
  • a phosphorescent material commonly used in mecanic horlogerie is marketed by the Japanese company Nemoto & Co. under the trade name Super-LumiNova.
  • the present invention aims to remedy the problems mentioned above as well as others by providing a timepiece comprising a dial with luminous index which gives in particular to the timepiece thus equipped appearance easily identifiable when this timepiece is consulted both in the dark and in daylight.
  • the present invention relates to a wristwatch comprising a watch case, a bezel rotatably mounted on the watch case and a dial provided with at least one luminous index, this luminous index being illuminated through the dial by less a light source arranged under the dial and powered by a source of electrical energy, an activation component of the light source being housed in the rotating bezel and cooperating with a detection component housed in the watch case, the activation component being arranged so that, in a determined position of the rotating bezel, its presence is detected by the detection component, the detection component then emitting an electrical signal which controls the ignition of the light source.
  • the present invention provides a wristwatch in which at least one luminous index allowing the reading in the dark as well as in broad daylight of information located on the dial, for example a time index, is illuminated at the request of the user by lighting a light source placed under the dial.
  • a light source placed under the dial.
  • a wristwatch is thus obtained whose hour markers with which the dial is equipped can be illuminated on demand by means of one or more light sources, which confers on the wristwatch according to the invention when it is consulted at night by its wearer a unique appearance that can not be confused with the appearance of another wristwatch.
  • Provide an activation component in the bezel of the wristwatch and a corresponding detection component in the box of the watch can turn on the light source on demand because it is obvious that it is not possible , both for reasons of autonomy of the source of electrical energy and for aesthetic reasons, to let the light source shine permanently.
  • controlling the ignition of the light source by means of a rotating bezel is very easy. It is indeed easier for the user to grope in the darkness the bezel and rotate it until the light source turns on, that having to detect the presence for example of a small push-button at one point of the watch case and press it to engage the light source.
  • the present invention proceeds from the general inventive idea of illuminating one or more indexes, for example time indexes, and / or one or more logos formed on the surface of a dial by means of one or more several light sources arranged under the dial and whose ignition is controlled by means of a rotating bezel mounted on the watch case.
  • the present invention makes it possible to significantly differentiate the visual appearance of such a watch the appearance of competing watches when these watches are viewed by their user.
  • the box of the wristwatch according to the invention comprises a middle part 2 on the top of which is mounted a rotating bezel 4.
  • a set of hands 6 hours, minutes and seconds moves over a dial 8 provided with fixing feet 10 and covered by an ice 11.
  • the dial 8 comprises at least one and, in the example illustrated in particular at the figure 2 , four indexes 12a, 12b, 12c and 12d arranged at noon, 3 hours, 6 hours and 9 hours. These four indexes 12a-12d are formed, for illustrative purposes only, four isosceles triangles equidistant from the edge of the dial 8 and whose vertices point to the center of the dial 8.
  • a fifth index, referenced 12e corresponds for example to the commercial logo ⁇ of the Applicant. This fifth index 12e is placed under the first index 12a, at a lower distance from the center of the dial 8. It will be understood that this is a simple construction choice and that the present invention is not limited by the number, shape and location of 12a-12e indexes.
  • the first technique is to provide a transparent dial 8 which is covered with a layer of paint except where the indexes 12a-12e are provided.
  • a second technique consists in providing an opaque dial 8 in which the shapes corresponding to the indexes 12a-12e are pierced. In the latter case, the holes corresponding to the indexes 12a-12e will preferably be sealed by means of small adhesive coupons 14 which will be glued by the underside of the dial 8. These adhesive coupons 14 may, as desired, be transparent or diffusing, white or colored.
  • a first printed circuit sheet 16 of substantially circular profile and whose diameter is slightly smaller than that of the dial 8 is bonded by its upper surface 18 against the lower surface 20 of the dial 8.
  • a possible manufacturing technique is to provide the lower surface 20 of the dial 8 of strips of double-sided adhesive tape, then press the first printed circuit board 16 against the dial 8.
  • the lower surface 20 of the dial 8 against which the upper surface of the first printed circuit sheet 16 is to be plated is provided, at the places which will be in correspondence with the indexes 12a-12e formed in the dial 8, with four light 22a, 22b, 22c and 22d of rectangular overall shape and whose dimensions slightly exceed those of the indexes 12a-12e.
  • the light guides 22a-22d are provided with ears 24 for mounting under the dial 8.
  • the mounting lugs 24 are asymmetrical, which provides a means of foolproofing to prevent that the light guides 22a-22d are mounted upside down under the dial 8.
  • the lower surface 20 of the dial 8 is provided with recesses 23a-23d whose profile corresponds to that guides of light 22a-22d.
  • the light guides 22a-22d are glued under the dial 8 by their ears 24. This makes it possible to guarantee the presence of a thin layer of air between the light guides 22a-22d and the lower surface 20 of the dial 8 at the locations where the light guides 22a-22d are not covered with glue, whereby the light will propagate by total reflection within the light guides 22a-22d.
  • the upper surface 18 of the first printed circuit sheet 16 by which the latter is to be pressed against the lower surface 20 of the dial 8 is provided at the places which will be in correspondence with the light guides 22a, 22b, 22c and 22d.
  • light sources 28 for example of the light-emitting diode type. These light sources 28 are arranged on the upper surface 18 of the first printed circuit board 16 in such a way that, when the first printed circuit board 16 is glued against the lower surface 20 of the dial 8, the light sources 28 are disposed opposite the narrow sides 30 of the light guides 22a-22d which are located opposite the periphery of the printed circuit sheet 16.
  • These light sources 28 are coupled optically with the light guides 22a-22d of so that the light they emit in a horizontal direction propagates inside the light guides 22a-22d by total reflection.
  • the first printed circuit sheet 16 is preferably pierced with holes 31 in which the feet 10 of the dial 8 will be engaged.
  • the light guides 22a-22d can be dispensed with and the light sources 28 placed directly below the indexes 12a-12e. It can also be envisaged to use light sources 28 illuminating vertically upwards and, if necessary, to associate them with diffusing lenses to illuminate a larger area.
  • the 22a-22d light guides can be diffusing. In this case, the small adhesive coupons that close the holes corresponding to the indexes 12a-12e formed in the dial 8 can be transparent.
  • the diffusing light guides have the disadvantage of diffusing the light isotropically; they therefore lack directivity, which can lead to a lack of brightness of the indexes.
  • transparent light guides for example made of polymethyl methacrylate or PMMA, and in which structure light extractors whose function is to extract upwards towards the indexes injected light by the light sources 28 in the light guides.
  • structure light extractors whose function is to extract upwards towards the indexes injected light by the light sources 28 in the light guides.

  • the casing ring 38 is itself fixed by screwing and clamping in the middle part 2.
  • the clockwork movement 36 can be of any type, for example purely mechanical or electromechanical.
  • the invention is particularly advantageous in the case where the wristwatch is equipped with a purely mechanical movement since it allows to associate with such a mechanical wristwatch an electric lighting function without having to make any changes to the movement mechanical.
  • a second printed circuit sheet 42 which carries the electronic power supply and control assembly 32 is disposed under the casing ring 38.
  • This second printed circuit board sheet 42 includes a connector 44 in which the connection tab is engaged.
  • the connecting tab 34 makes it possible to directly connect the light sources 28 carried by the first printed circuit sheet 16 to the electronic programming and power management electronic components 46 carried by the second printed circuit sheet 42, by stepping over the movement timepiece 36 housed in its casing ring 38. Thanks to this characteristic, it is possible to provide a purely mechanical watch of an electric lighting device without having to modify the movement 36.
