Definitions

  • the present invention relates to a timepiece comprising a receiving and / or transmitting antenna radio signals.
  • Timepieces of this type which are often made in the form of a wristwatch, are used in various applications. They are sometimes intended to communicate remotely with a device, by example, as part of an identification system of objects.
  • each wristwatch has a memory device containing a code unique identification for this wristwatch, a circuit for transmitting and receiving radio broadcast signals and an antenna connected to it.
  • Such a system further includes a transceiver central arranged to transmit a signal question mark.
  • the detection of this signal generates the transmission of an identification signal by the wristwatch in question, this signal being representative of the identification code stored in its device memory. So by identifying the wristwatch that belongs to each identification signal, the transceiver central can control the identity of the bearer of the wristwatch.
  • Patent application CH 686 696 describes a wristwatch in which the antenna is placed in a interior recess of the middle part and the bezel. This antenna is electrically connected to a circuit transmission and reception of radio signals which is mounted under the dial of the wristwatch. The circuit transmission and reception of radio signals and the antenna are powered by a battery housed in the part bottom of the wristwatch case.
  • This arrangement makes it possible to install in a box a antenna whose dimensions are as large as possible, given the dimensions of the wristwatch, so as to offer the largest section effective possible to electromagnetic fields. Moreover, the antenna housing at the bezel allows minimize the distance between the antenna and a source of radio signals when approaching the wristwatch this source.
  • the ends of the wire constituting the antenna housed in an interior recess of the middle and / or the telescope must be connected to the circuit housed at inside the case in the reserved space usually the watch movement. This connection is carried out by complex and costly means. Then the changing the antenna and / or the transmission circuit and reception of broadcast signals is difficult to perform and requires to open the case and disassemble the elements housed there.
  • connection of the antenna to the circuit transmission and reception of radio signals is performed during assembly of the part, which complicates the manufacturing and the risk of poor electrical contact is present in the embodiment of said connection offers.
  • This wristwatch is therefore expensive and limited. in its use, the circuit generally being dedicated to a specific application and the transponder being permanently associated with the watch in which it is arranged during the manufacture of this watch.
  • the present invention aims to provide a timepiece including a receiving antenna and / or transmission of a radio broadcast signal which overcomes the disadvantages of the aforementioned prior art.
  • the invention also aims to provide a timepiece including a receiving antenna and / or transmission of a radio-broadcast signal, the realization is simple and reliable.
  • the invention also aims to provide a part clock industry comprising a receiving and / or transmission which facilitates the change of the antenna and / or of the circuit for transmitting and / or receiving radio-broadcast signals.
  • the present invention relates to a
  • timepiece comprising a case, a bezel and a transponder comprising a transmission and / or reception of a radio broadcast signal and an antenna connected to the sending and / or receiving circuit.
  • the room watchmaking is characterized in that the antenna and the both transmitting and / or receiving circuits secured to the bezel.
  • the transponder can be assembled before to be assembled to the bezel of the timepiece, this reliably.
  • the transponder can be assembled before to be assembled to the bezel of the timepiece, this reliably.
  • by simple disassembly of the telescope or by simply changing the telescope it is possible to change the transponder associated with a given timepiece.
  • the part clockwork 1 conventionally comprises a housing which includes a middle part 2 and a crystal 12.
  • the middle part 2 is made, for example, of a plastic material by a well known injection technique.
  • the timepiece 1 further comprises a horometric movement 4 which is housed inside the middle 2 and which is mechanically coupled here to indicators 6, 8 and 10 formed respectively by a second hand, minute hand and hour hand.
  • the timepiece 1 is sealed by the glass 12.
  • the latter is fixedly mounted on the middle 2 in a conventional manner, for example by a bonding or ultrasonic welding technique.
  • a bezel 14 is mounted on the case, namely on the glass 12 and / or middle 2.
  • the wristwatch 1 further comprises a transponder 16 comprising an antenna 20 and a circuit 22 for transmitting and / or receiving radio broadcast signals, these elements being well known to those skilled in the art.
  • the antenna 20 and said circuit 22 are integrated into the bezel 14.
  • the watchmaking part (middle, crystal, movement, dial, hands, etc.) and the receiving and / or transmitting part (antenna, circuit) of the wristwatch can be designed, manufactured and tested completely separately from each other before the final assembly of the wristwatch.
  • the transponder 16 further comprises means supply to the circuit 22.
  • the supply means 17 can be realized by an energy source such than a battery or, preferably, by a circuit rectification of the signals picked up by said antenna 20. In the latter case, it is easier to integrate completely the transponder 16 in the bezel 14 for this which concerns the size.
  • the bezel 14 is mounted on the housing removably.
  • the glass 12 and the bezel 14 have a protuberance 26 and a groove 28 complementary so that the bezel is retained in place around the housing.
  • the bezel 14 can be made of an elastically deformable material of so that the bezel 14 is removable, that is to say that it can be assembled to the housing and disassembled from the latter by a simple press.
  • the bezel 14 is removable makes it possible to choose and easily change communication system (i.e. the sending and / or receiving circuit) or resonant frequency of the unit formed by the antenna and the transmission and / or reception circuit, depending on the country or desired service.
  • such an arrangement allows to sell the case and the bezel separately.
  • the consumers can choose both a wristwatch that suits him and match his wristwatch a telescope containing the antenna and the transmission circuit and / or reception corresponding to the service sought.
  • the separation of the horological elements of the antenna and the transmitting and / or receiving circuit allows the realization of a receiver or a transponder little expensive which can be combined with a wristwatch removable way.
  • the bezel 14 includes a clearance mounting 18 in which the antenna 20 and the circuit 22 for transmitting and / or receiving radio broadcast signals are housed.
  • the clearance 18 has a shape annular which follows that of the telescope 14.
  • the antenna 22 has an annular shape.
  • This antenna can be constituted by a coil comprising a or more turns arranged in a plane substantially parallel to that of dial 24 of wristwatch 1.
  • the present invention is applicable to any form of antenna capable of being integrated into a glasses.
  • Clearance 18 is formed in a surface outside of the bezel 14, that is to say in a surface seen by the user when looking at the wristwatch when wearing it. Clearance 18 is closed with a transparent cover 30 in order to make visible to the user the antenna 20 and the transmission circuit 22 and / or reception, this being a choice in no way limiting.
  • the cover 30 closes the clearance 18 and protects the antenna 20.
  • the bezel 14 housing the antenna 20 and the circuit 22 transmission and / or reception can, in case the antenna 20 or circuit 22 is not working properly or is not not suitable for a desired application, be easily replaced by another telescope.
  • Clearance 18 can also be filled at least partially by fixing means, such as an adhesive or a resin, to better ensure the stability of the assembly antenna 20 and circuit 22 for transmission and / or reception in the telescope 14.
  • fixing means such as an adhesive or a resin
  • the mounting clearance 18 has two non-coplanar surfaces 36 and 38, on which are mounted circuit 22 and antenna 20 respectively.
  • the dimensions, placement and orientation of the antenna 20 and circuit 22 can be optimized with respect to those of the bezel 14.
  • FIG. 3 represents a variant of the mode of production of the timepiece described above.
  • the mounting clearance 18 has a substantially flat surface 40 on which antenna 20 and circuit 22 for transmission and / or reception are mounted.
  • the antenna 20 and the circuit 22 are mounted on a common support 34 before being housed in the clearance 18 to facilitate assembly of the transponder in the bezel 14.
