Definitions

  • the present invention relates to a timepiece with special aesthetic effects. More precisely, the present invention relates to a timepiece exhibiting original plays of light.
  • timepieces such as wristwatches exhibiting an improved aesthetic appearance is a constant concern among watch manufacturers and in particular among those responsible for designing the various trim elements. It would take too long to list here all the solutions that have been considered to give a timepiece an appearance as neat and aesthetic as possible.
  • the present invention is part of the quest to offer customers watches whose appearance is both aesthetic and surprising.
  • US2008004510A1 discloses an embodiment in which an opening is made in the middle part such that the light guide of the bracelet can be inserted therein in order to improve the coupling of the light coming out of the middle part to the bracelet.
  • US6690623B1 describes a timepiece having a dial in which the light transported by optical fibers escapes through the appliques.
  • the present invention relates to a timepiece defined by independent claims 1 and 2.
  • Dependent claims 3-12 define various embodiments.
  • the present invention provides a timepiece whose aesthetic appearance can be varied almost infinitely.
  • the light source being housed in the interior volume of the watch case, it is for example possible to envisage the middle part being partially or totally transparent, so that the light produced by the light source diffuses through said middle part.
  • the dial can be designed to be completely opaque and only let light escape at the level of the appliques. It is also possible to provide for covering a transparent dial with an opaque mask which, itself, only lets light escape at the level of the appliques.
  • the light produced by the light source directly illuminates the transparent or translucent zones of the covering element or elements through which it is desired that the light come out.
  • This variant is applicable when no obstacle comes between the light source and the covering element to be illuminated.
  • the light source is a light-emitting diode or LED which emits ultraviolet, violet, blue, white or infrared light and the covering element is made of a plastic material loaded with fluorescent particles and / or phosphorescent.
  • the fluorescent and / or phosphorescent particles absorb the emitted radiation and re-emit a homogeneous visible light.
  • the light effect ceases immediately after extinction of the light source or, on the contrary, continues by an afterglow effect.
  • the light produced by the light source is injected into a light guide which then brings the light to the level of the transparent or translucent zone or zones of the covering element or elements considered.
  • the light guide is an optical fiber which makes it possible to bypass any obstacles which may arise between the light source and the transparent or translucent zone of the covering element considered through which the light will escape. the interior volume of the watch case.
  • the optical fiber can be an optical fiber which diffuses the injected light over its entire length.
  • the light source is a light-emitting diode or LED mounted on a support of the printed circuit board or PCB type together with its electronic control circuit.
  • the light source is powered for example by an interchangeable or rechargeable battery or even by a solar cell.
  • the covering element concerned can be opaque in the mass or be coated with an opaque paint layer.
  • the present invention proceeds from the general idea which consists in accommodating at least one light source in the interior volume of a watch case, the light produced by the light source being able to escape to the outside of the watch case through at least one covering element of the watch intended to be at least partially transparent or at the very least translucent. This provides a timepiece with original aesthetic effects and having an extremely attractive appearance in the dark or in the dark.
  • the figure 1 is a sectional view of a caseband 1 delimiting with a back 2 and a dial 3 an interior volume 4 of a watch case 6.
  • the watch is an electronic watch and that its movement M is placed in the back of the watch case 6.
  • a support plate 8 of the printed circuit board or PCB type on which are mounted a light source 10, for example of the light-emitting diode or LED type and its electronic control circuit 12.
  • the light source 10 is powered for example by a battery 14 rechargeable or interchangeable and conventionally arranged under the watch movement M on the side of the bottom 2 of the watch case 6.
  • the watch can be electronic, electromechanical or even purely mechanical.
  • a crown of light around a control member of the watch such as a push-button 16.
  • a control member of the watch such as a push-button 16.
  • the caseband 1 is metallic, we practice in the latter a through hole 18 in which is engaged a transparent or at least translucent cylinder 20 which will serve as a light guide for the light which escapes from the watch case 6.
  • the outside diameter of the transparent or translucent cylinder 20 must be greater than the outside diameter of the head of the push button 16.
  • the cylinder 20 can also serve as a mechanical guide for the push button 16.
  • the middle part 1 is made of a transparent or translucent material such as a plastic material, a ceramic material, sapphire or fused silica, it can be tinted in the mass except in a region surrounding the push-button 16 where the material remains transparent or translucent according to the present invention. It is also possible, to simplify the process for injecting the plastic middle part 1, tint the latter in the mass throughout its volume, then machine a through hole in which a transparent or translucent cylinder is engaged as explained above in conjunction with a metallic caseband.
  • Yet another solution consists of producing the middle part 1 by injecting a transparent plastic material, then coating the inner face of this middle part with a layer of light-absorbing material except in the region surrounding the push-button 16.
  • a transparent plastic material to vary the effects in particular in the vicinity of the push-button 16, it is also possible to overmold a transparent or translucent plastic material on the covering element in question made of an opaque material.
  • any type of light source such as an incandescent lamp, light-emitting diode, organic light-emitting diode or the like can be used.
  • a light-emitting diode emitting ultraviolet, violet, blue, white or infrared light is used in combination with a middle part made of a plastic material loaded with fluorescent and / or phosphorescent particles.
  • the fluorescent and / or phosphorescent particles absorb the radiation emitted by the diode and re-emit a homogeneous visible light.
  • fluorescent and / or phosphorescent the light effect ceases immediately after extinction of the light source or, on the contrary, continues by an afterglow effect.
  • the watch trim element (s) which allow all or part of the light produced by the light source to pass through can be illuminated directly by this light source.
  • These trim elements can nevertheless also be illuminated indirectly by the light source.
  • the light guide 22 is an optical fiber which makes it possible to bypass any obstacles which may arise between the light source 10 and the transparent or translucent zone of the covering element considered through which the light will escape from the interior volume 4 of the watch case 6.
  • the optical fiber can be an optical fiber which diffuses the injected light over its entire length.
  • the middle part has been described as the only trim element. It must be understood, of course, that we are in no way limited to this single element and that the other elements of the watch which are the back, the dial, the bezel, the flange, the strands of the bracelet and others may be similarly considered.
  • the appliques 24 can for example be illuminated at the level of the bezel 26 and the dial 3.
  • the bezel 26 and the dial 3 can be provided completely opaque and do not leave escape of the light only at the level of the wall lights 24.
  • the bezel 26 and the dial 3 in a material, for example plastic, transparent or translucent, and then cover them with a mask in an opaque color which, also, only lets light escape at the level of the appliques 24.
  • the dial 3 can be transparent or translucent and the appliques 24 opaque. It is also conceivable that the bottom 2, the caseband 1 and the dial 3 are opaque and that only a flange disposed between the bezel 26 and the dial 3 is transparent or translucent, thus creating a luminous ring all around the crystal 34.
  • a caseband 1 which has two transparent zones 32a and 32b substantially at noon and at six o'clock, that is to say at the places where the strands 30 of the bracelet are attached to said middle part 1.
