Definitions

  • the present invention relates to a clock module for a timepiece, and more particularly a clock module of a wristwatch.
  • Such modules comprise a striking barrel which meshes with a ringing device driving a striking hammer, this hammer striking a timbre intended to be vibrated to emit a sound at a desired frequency, in order to produce a signal alarm at a predetermined time by a user of the module.
  • This alarm module is further provided with a control device operated by means of a push button and for displaying visual information, indicating to the user whether the alarm mechanism is activated or deactivated. Simultaneously with the display of this information, the control device blocks or unlocks the alarm tone and, more particularly, the striking hammer.
  • the striking hammer could, instead of producing an audible alarm signal, for example strike a pin to generate a silent alarm, such as a vibration that the user might feel.
  • a silent alarm such as a vibration that the user might feel.
  • the alarm module described in the document WO 2006/103289 A2 includes a first striking mechanism having at least one hammer for striking at least one stamp, and a second striking mechanism having at least one hammer for striking at least one non-resonant object.
  • the latter allows the alarm module to operate in a so-called discrete mode, that is to say that the ring does not implement hammers and timbres emitting sound frequencies, but a striking hammer a non-resonant object, for example a pin fixed in the bottom of a suitable watch.
  • the alarm module instead of generating an audible alarm signal, the alarm module generates vibrations that can be felt by the wearer of the watch.
  • the user To choose one or the other of these modes and to activate the corresponding function, the user must select it. Similarly, the user can disable the alarm module, which is a so-called silent mode.
  • the wake-up modules described above have several disadvantages, such as the lack of flexibility based on the user's choice of binary choice, ie the choice between an audible or silent alarm signal. More particularly, the user can only activate or deactivate the audible ringer which, once triggered, operates until the complete disarming of the ringer barrel. Therefore, in the case where the user would not want to use a silent bell and would feel embarrassed by a continuous audible ring, the use of these alarm modules is not satisfactory for the user.
  • the alarm module described in the document WO 2006/103289 A2 requires for its realization a large number of parts which must be coordinated and adjusted in order to have a correct functioning. Moreover, this alarm module does not allow the user to recognize at any time whether he has chosen the audible or silent ring.
  • the present invention aims to provide a timepiece having an improved alarm module adapted to generate at least two different audible alarm signals while requiring for its implementation a limited number of parts.
  • This object is achieved by a timepiece comprising an alarm module having the features of the independent claims. Preferential variations of execution are the subject of the dependent claims.
  • the Fig. 1 illustrates as an example an alarm module 10 mounted on a plate 20 disposed in a box of a timepiece, such as a wristwatch, which is also provided with a timepiece device.
  • a timepiece such as a wristwatch
  • This is only schematically represented by an hour wheel 21 mounted using a fixing pin 22 on the Platinum 20.
  • a more detailed illustration has been omitted for the sake of clarity and for simplicity of representation.
  • the timepiece comprises a conventional clockwork movement intended to ensure the energy supply of the timepiece device and an additional movement intended to ensure the power supply of the alarm module 10.
  • a conventional clockwork movement intended to ensure the energy supply of the timepiece device and an additional movement intended to ensure the power supply of the alarm module 10.
  • the alarm module 10 is adapted, according to a preferred embodiment, to generate an alarm bell for the timepiece. More particularly, the alarm module 10 is designed to generate a first audible alarm signal in a first mode of operation and a second audible alarm signal in a second mode of operation.
  • the first audible alarm signal may be a continuous tone and the second audible alarm signal may be a tone interrupted by one or more temporary intervals.
  • the wake-up module comprises an operating mode selection mechanism 30, a command transmission mechanism 50 and a striking mechanism 60.
  • the operating mode selection mechanism 30 is provided with a push button 31 accessible from outside the timepiece box.
  • This push button 31 can be actuated by a user of the timepiece wishing to change the operating mode of the alarm module 10.
  • the push-button 31 is arranged to act on a head 32 provided at one end with a mode-changing arm 33.
  • the latter additionally comprises a perpendicular arm 37, and is fixed at its other end to a heel 35 with a screw 34.
  • it can be welded to the heel 35, for example by laser welding.
  • the heel 35 is mounted with a screw or a pin 36 on the plate 20 to allow the pivoting of the mode change arm 33 around the screw or the pin 36 when the push button 31 is operated. Note however that other means of mounting the heel 35 on the plate 20 are generally contemplated, also allowing the pivoting of the mode change arm 33.
  • the heel 35 may be provided with a pin adapted to be driven then riveted in the deck 20.
  • the perpendicular arm 37 meshes with a column wheel 38.
  • the latter in turn meshes with the command transmission mechanism 50 which is adapted to modify the operation of the striking mechanism 60 when the second operating mode is selected, to allow the one to operate. to generate the second audible alarm signal.
  • the composition and operation of the control transmission mechanism 50 is described in greater detail below, with reference to the Fig. 2 to 5 .
  • the column wheel 38 additionally meshes with a display mechanism of the selected mode 40 adapted to display an indication representing the selected operating mode.
  • This display mechanism of the selected mode 40 includes a display lever 41 mounted to the plate 20 by means of a screw or a pin 44 for pivoting the display lever 41 around it. Note however that other mounting means of the display lever 41 on the plate 20 are generally contemplated, also allowing the pivoting thereof.

In the first display position, illustrated in the Fig. 2 , the "A" is displayed, and in the second display position, illustrated in the Fig. 4 , the "B" is displayed.
  • the striking mechanism 60 comprises a striking hammer 63, and a stamp 65 intended to be struck by the striking hammer 63 to vibrate freely at its own sound frequency, in order to generate one of the first and second audible alarm signals.
  • the stamp 65 consists, for example, in a spring steel blade or hardened steel, which is strongly fixed by one of its ends to the plate 20. This steel blade surrounds at least a part of one of the movements distinct from the timepiece. In the Fig. 1 , fixing of the stamp 65 is effected for illustration by a heel 64 mounted on the plate 20.
