Definitions

  • the present invention relates to an electronic timepiece with analog display comprising an electronic movement powered by an accumulator, photoelectric cells ensuring the charging of the accumulator and a dial having cutouts arranged opposite the photovoltaic cells.
  • the present invention aims to achieve a construction concept applicable to all types of movements, allowing very flat movements to be carried out and facilitating the automatic assembly of the components. of the watch.
  • the electronic timepiece according to the invention is characterized in that the accumulator is mounted on an annular piece surrounding the movement and carrying the photovoltaic cells located opposite the dial, as well as the components of the electrical circuit. connecting the photovoltaic cells to the accumulator.
  • the annular part, with its circuit, its photovoltaic cells and the accumulator, constitutes a ring-shaped module easily mountable around the movement.
  • This ring can simultaneously serve as a casing ring for the movement. In the case of a movement from one piece with the case back, the movement will also fit into the ring, between the case and the dial.
  • the accumulator is itself in annular shape and occupies most of the volume of the ring.
  • the capacity of such an accumulator can be very important, while the space it occupies corresponds practically to that of a movement casing ring.
  • Figure 1 is a plan view of a wristwatch valid for the three embodiments.
  • Figure 2 is an exploded view of the first embodiment.
  • Figure 3 is an exploded view of the second embodiment, without the middle-bezel identical to that of the first embodiment.
  • Figure 4 is a plan view of the ring surrounding the movement according to a third embodiment.
  • the watch shown in FIGS. 1 and 2 includes a case made up of a metal bezel-frame 1, a lens 2 fixed in a notch of ice in the frame-bezel 1 and a bottom 9 coming to be fixed to the notch in the middle- bezel 1.
  • the middle part bezel 1 is provided with two pairs of horns 3, 4, and 5, 6 for attaching a bracelet. Below the notch of ice, the middle-bezel has a range 7, the rest of the interior of the middle-bezel being simply constituted by a cylindrical face 8.
  • the watch according to the first embodiment ( Figure 2) comprises a movement 10 integrated into the metal back, as found on the market.
  • the movement is surmounted by a dial 11 which comes to rest against the surface 7 of the middle-bezel, leaving sufficient space for the hands 12 and 13.
  • the movement 10 is surrounded by a circle 14 of synthetic material having a cylindrical skirt 15 adapted to the movement and a flange 16 in contact with the dial.
  • the puddle 16 has rectangular recesses distributed over the periphery and each containing a photovoltaic cell 17.
  • an accumulator 18 of annular shape.
  • the dial 11 has, at its periphery, rectangular cutouts or notches 19, each of these cutouts being situated opposite a photovoltaic cell 17. These cutouts 19, preferably 4, 6 or 12 in number, can occupy the locations of time signs.
  • the annular part 14 further carries the diode and the capacitor of the charging circuit of the accumulator 18.
  • the galvanic connection of the accumulator to the movement 10 can be ensured on the one hand by the base 9 and, on the other hand, by a metal tongue 20 inside the ring 14.
  • the dial 11 can be omitted, the movement then being visible and the time signs being directly constituted by the photovoltaic cells 17.
  • the second embodiment represented in FIG. 3, comprises the same middle-bezel 1.
  • the bottom 21 is a simple metallic bottom fixed to the notch in this middle-bezel.
  • Movement 22 is any commercial movement, for example a 6 3/4 x 8 movement.
  • Such a movement has a battery compartment in which there is a contact tab 23 which can be folded down so as to protrude outside the metal cage of the movement to establish contact with the bottom 21.
  • This annular part 14 also has a contact tongue 20, but directed in the other direction.
  • FIG. 4 A third embodiment using such an accumulator is shown partially in FIG. 4.
  • this piece is shown, this piece, massive, presenting a housing for a small accumulator 25 in the form of pastille.
  • this annular part 24 is similar to part 14 of the other embodiments. It also carries photovoltaic cells 17 and a housing is provided for the diode and the capacitor of the charging circuit of the accumulator.
  • the accumulator 25 vertically occupies a space situated in the thickness of the movement and therefore makes it possible to produce very flat watches.
