Definitions

  • the invention relates to a small radio clock according to the preamble of claim 1.
  • This can be a wristwatch or a watch worn in some other way, for example on a piece of clothing, and for example a small alarm clock or a small style fireplace clock.
  • the JUNGHANS radio-controlled clocks in the form of table or wall clocks with features as described in more detail in EP-OS 0 180 155 have quickly become market leaders.
  • the realization of a radio clock on the order of a wristwatch was not considered realistic by experts (see R. Bermbach and M. Lobjinski "New Radio Clocks from the Institute for Data Technology" in FUNKUHREN, edited by W. Hilberg , Middle of page 170).
  • an antenna is no longer attached separately inside the watch case next to the movement capsule behind the dial, as is the case with the wall and table clocks on the market.
  • an antenna is incorporated directly into the watch case, namely integrated into the case edge (depending on the case material on the inside or the outside of the case wall).
  • an antenna coil can be arranged coaxially with the housing, using the ferromagnetic parts of the housing and the work as components of a coil core which are displaced more or less from the coil center in the direction of the effective field components.
  • the antenna coil is carried directly by a core made of ferrite powder or soft magnetic particles which is shaped in accordance with the housing design and whose outer contour can be adapted to the design requirements of the housing.
  • the small radio-controlled watch 11 sketched in FIG. 1 in top view can be designed with a digital or - as shown - analog time display and, for example, as a wristwatch, that is to say with a bracelet 12 connected to it, the housing 13 receiving the time telegram receiver 14.
  • the magnetic antenna 15 has a coil 17 penetrated by a highly permeable core 16. In the interest of optimal performance of the antenna 15, this is arranged in or next to the side area of the watch dial 18 (for digital or analog time display) in the direction of the greatest longitudinal extent of the housing 14, oriented transversely to the clockwork (numerical wave) axis.
  • the antenna coil 17 can be located inside the housing 14 if the housing 14 - at least in the vicinity of the antenna 15 - consists of electrically non-conductive material. Otherwise, the antenna 15 according to FIG. 1 is arranged next to the dial 18 outside on the watch housing 14.
  • the antenna core 16 can extend over the longitudinal extent of the housing 14 into the connection areas of the bracelet 12 in order to achieve a great length and thus a sensitive antenna 15. 1, the housing 14 and the connection area of the bracelet 12 are then expediently designed in such a way that a housing integration of the antenna core 16 results; whereby it can be quite interesting not to choose a symmetrical structure, on the one hand not to unnecessarily increase the total volume of the clock 11 and on the other hand to advertise effectively that it is a radio-controlled wristwatch 11.
  • the antenna 15 can also be divided into two ferrite rods as the cores 16 for coils 17, in order to achieve a more compact arrangement for the integration of the antenna 15.
  • the rod cores 16 can also be arranged at an angle to one another in or on the watch case 14 (depending on the material thereof) and can be of different lengths, for example in order to improve the directional characteristics of a ferrite rod antenna that are not desired per se in the direction of better all-round reception influence (as described in detail in EP-OS 0 242 717).
  • the watch housing 14 itself is designed as the antenna core 16, for example is made of pressed material with injected ferrite grains or soft magnetic particles.
  • This housing core 16 can then be U-shaped in plan view or O-shaped according to FIG. 4 or also according to FIG. 5 as a flat pot, that is to say with a continuous bottom 19.
  • the interior 20 accommodates the clockwork 13 located under the dial 18.
  • a single antenna 17 or a plurality thereof can be wound around a core extension 22 which extends in the direction of the radio field component 21 to be received, preferably embedded in a core incision 23 which acts as a winding body, but the coil 17 can also coaxially around one 5, where the core 16 is formed as a tube piece which is very short in relation to the diameter on the side of the watch case 14 facing away from the dial 18.
  • FIG. 6 shows an arrangement according to FIG.
