Definitions

  • the invention relates to the field of watchmaking and relates in particular to a device for setting the time of a watch.
  • time setting devices of a watch are integrated into the watch movement of the watch and are well known to those skilled in the art.
  • a commonly used time-setting device comprises one or more gears kinematically connecting a winding stem intended to be manipulated by a user to a minute wheel connected to a time display.
  • the invention relates to a device for setting the time of a watch, comprising a winding stem configured to occupy a time-setting position in which it is engaged with a time-setting gear train kinematically connected to a time display and to a 24-hour wheel.
  • the 24-hour wheel is engaged with a barrel comprising a barrel spring intended to provide the energy necessary for displaying a time value, the barrel comprising a ratchet mechanism configured so as to allow rotation of the barrel over more than one revolution when the winding stem winder is rotated in a first direction, and so as to limit the rotation of the barrel to an angular amplitude corresponding to less than one turn when the winding stem is rotated in a second direction.
  • the invention may further comprise one or more of the following features, taken individually or in any technically possible combination.
  • the time-setting gear train comprises a friction wheel configured to prevent the transmission of movement from the winding stem to the 24-hour wheel when said winding stem is rotated in the second direction and the barrel is forced into a stop position by the ratchet mechanism.
  • the time-setting gear train comprises a transmission wheel kinematically interposed between the friction wheel and the time display.
  • the transmission wheel is in meshing relationship with the 24-hour wheel and an hour wheel.
  • the barrel is configured such that the barrel spring is preloaded when the winding stem is rotated in the second direction and the ratchet mechanism prohibits rotation of the barrel.
  • the ratchet mechanism comprises a protrusion arranged on the barrel in an eccentric manner and extending parallel to the axis of rotation of the barrel, and a lever intended to cooperate with the protrusion so as to pivot the lever when the winding stem is rotated in the first direction, and so as to rest in abutment against said lever when the winding stem is rotated in the second direction.
  • the elastic member is formed by a disc having radial lobes on its periphery, intended to rest against the flange so as to ensure the rotational connection of said flange and the elastic member.
  • FIG. 1 shows a time-setting device 10 of a watch, intended to be integrated into a watch movement of said watch.
  • the time-setting device 10 is capable of setting both the time and the date of the watch.
  • the time-setting device 10 comprises a winding stem 11 on which a user of the watch is intended to act to set the time and possibly the date.
  • the winding stem 11 is configured to occupy a time-setting position in which it is engaged with a time-setting gear train 20 kinematically connected to a time display 30 and to a 24-hour wheel 31.
  • the time display 30 is constituted by hour and minute hands in the preferred embodiment of the invention.
  • the 24-hour wheel 31 is meshed with a barrel 40 comprising a barrel spring 40 intended to provide the energy necessary for displaying a time value, in particular the date.
  • the 24-hour wheel 31 is meshed with a ratchet 401 of the barrel 40.
  • the barrel 40 may be in accordance with that described in the patent EP3540524
  • the watch movement may include another barrel intended to provide the energy necessary for the rotation of the hour display 30.
  • the barrel 40 comprises a ratchet mechanism 41 configured so as to allow the rotation of the barrel 40 over an angular amplitude corresponding to more than one revolution when the winding stem 11 is rotated in a first direction, and so as to limit the rotation of the barrel 40 to an angular amplitude corresponding to less than one revolution when the winding stem 11 is rotated in a second direction.
