Definitions

  • the present invention relates to a timepiece comprising a middle part in which a movement is arranged, display means coupled to said movement and a receiving and / or transmitting device comprising at least one element providing an antenna function, said middle part comprising at least one opening through which is arranged a control member for said movement of substantially elongated shape defining a longitudinal axis.
  • timepieces of this type often produced in the form of wristwatches with various applications, such as pager watches, radio watches or telephone watches.
  • the present invention relates in a preferred mode to a timepiece whose receiving and / or transmitting device is a transponder.
  • a timepiece is intended to communicate remotely with a device, for example, in the context of an object identification system.
  • each wristwatch comprises a transponder comprising a memory device containing its own identification code, a circuit for reception and emission of radio broadcast signals and an antenna connected thereto.
  • FIG. 2 a section of the crown stem 8 along its axis longitudinal, this being coupled to the watch movement 10 through an opening cylindrical 11 formed in the middle part 2.
  • a gasket 12 for example of the gasket type lip, is arranged at the entrance of the opening 11 around the rod so conventional for sealing the watch 1 according to the invention.
  • the watch movement 10 is simply shown diagrammatically under dial 13 since it does not constitutes here only a secondary aspect of the invention, insofar as any type of conventional movement can be used.
  • the crown rod 8 has a housing 14 in the rod so that a transponder 15 can be placed there.
  • the transponder 15 includes an antenna 16 and a signal transmission and / or reception circuit 17 radio-broadcast, these elements being well known to those skilled in the art.
  • the antenna 16 is preferably of the coil type 18 wound around a ferromagnetic core 19.
  • the antenna 16 and the circuit 17 are arranged on the same printed circuit 20, one at the following the other, so as to reduce their bulk.
  • the crown stem 8 is made of an electrically insulating material to avoid creating a magnetic shielding around the antenna 16 of the transponder 15.
  • a slot 21 (visible in FIG. 1) has been formed therein so as not to disturb the operation of the antenna 16 of the transponder. Indeed, without the presence of this slot 21, the passage of a magnetic flux through the antenna 16 would have consequence, in this case, of inducing the appearance of eddy currents in the middle, around opening 11. These eddy currents would in turn induce the appearance of a magnetic field opposing the field having induced them, and therefore reception by antenna 16 of radio-broadcast information communicated by a central system.
  • the integrated circuit 17 of the transponder 15 is arranged in the timepiece movement 10, preferably near the crown stem 8 on the printed circuit 24 of the movement 10, for example, if the watch is of the electronic type.
  • Electrical connection means are also provided in this case for connecting the two terminals of the antenna 16 to the integrated circuit 17.
  • These connection means are shown here by elastic metal blades 25, 26 secured to the printed circuit 24 and connected by metallization tracks 27, 28 to the integrated circuit 17.
  • These metal blades 25, 26 are in permanent contact with respective zones 29, 30 of the rod, formed by metallizations isolated from one another and produced over the entire circumference of the stem, in places spaced along its longitudinal direction.
  • These respective metallization zones 29, 30 are then connected inside the rod, for example by means of copper wires 31, 32, respectively to one and the other terminal of the antenna.
  • this variant has a greater structural complexity than the previous one, it allows flexibility upper in the dimensioning of the crown stem 8.
  • the pushbuttons generally present in the field of watchmaking has a greater diversity of forms than crown stems. This allows advantageously to a manufacturer of the watch according to the present invention to choose in a wider range of choices, than in the first embodiment previously described, the geometry of the button he wishes to use. This one can therefore more easily adapt the geometry of the push button rod to the structure of the transponder it has at its disposal.
  • FIG. 5 schematically represents a second variant of this embodiment similar to that of FIG. 3, in which the transponder 15 is only partially disposed in the housing 14 of the rod of the push button 9.
  • the numerical references are the same for the elements already described.
  • the connection means electrically connecting the antenna 16 to the integrated circuit 17 of the transponder.
  • the push button 9 does not have necessarily a symmetry of axial revolution as is the case for a crown stem 8, but above all, the button and its rod are not caused to rotate during use. Consequently, the metallized electrical contact zones 29, 30 described for the stem-crown can be limited here to one face of the stem, opposite elastic metal connection blades 25, 26, instead of covering the entire periphery.
