Definitions

  • the present invention relates to a mechanism for chronograph watch movement.
  • the present invention also relates to a chronograph watch movement comprising such a mechanism, as well as a chronograph watch, in particular a wristwatch chronograph watch, comprising such a movement.
  • a chronograph watch is a time device that allows a measurement of duration.
  • the chronometer is a precision time machine.
  • a chronograph may or may not be a chronometer.
  • a chronograph watch is a watch having at least one indicator such as a needle which can be turned on and off by means of a pushbutton or other control device in order to measure a duration. . Then it can be brought back to its starting point.
  • Many chronographs also have indicators for displaying the current time in addition to displaying the measured duration.
  • the indicator or second-hand needle (also called “second chronograph indicator” or “second chronograph hand”), which is at rest on the zero division of the dial, starts up (“START” phase).
  • a second pressure on the same pusher or on another pusher has the effect of stopping the second hand at the precise point where it was during this pressure (phase “STOP").
  • STOP the precise point where it was during this pressure
  • the second hand quickly returns to its starting point, that is to say on the zero division of the dial (phase "RESET”). In this way, it is possible to measure a duration in seconds.
  • the three phases or functions of a chronograph watch are therefore the start or start, the stop or stop and the reset or reset.
  • a possible known chronograph mechanism is that with the column wheel that uses two pushers or control devices, one for the "START” and “STOP” functions, the other for the reset ("RESET").
  • the usual chronograph watches take the energy necessary for the operation of the part of the movement allowing the measurement of a duration, on the kinematic chain making it possible to count and display the current time, that is to say on the chain kinematic linking a power source, for example a cylinder, to the regulating member and to the wheels of the watch, which are linked to the indicators of the watch in order to display the hours, minutes and / or seconds current.
  • a power source for example a cylinder
  • a wheel indicates a mobile which can be rotated and which allows a clutch with a toothing of another mobile.
  • a wheel is a gear wheel.
  • Such a wheel is generally linked to an indicator, for example a needle.
  • counter indicates a means providing information relating to a counted duration. More precisely, a dial and an indicator form a counter.
  • control devices may be cam or column wheel. As they are known per se in the field of technology, they will not be described here.
  • Known clutch devices can engage the seconds wheel of the current time (also called “second movement wheel” or “seconds wheel”) to the second chronograph wheel.
  • the second chronograph wheel is used to drive a seconds indicator that makes a full turn of the dial when the time has reached an integer of seconds, in most cases sixty seconds.
  • the second chronograph wheel causes, for example by means of a gear train, other wheels that can count a time timed, usually a wheel of chronograph minutes, or even a chronograph hour wheel.
  • the energy from the "basic movement”, that is to say the movement that displays the current time (seconds, minutes and / or hours) is then redistributed to the different wheels that allow to count a time timed directly by the second chronograph wheel.
  • Vertical clutch devices allow a so-called “vertical” clutch between the two kinematic chains, in particular between a wheel of a kinematic chain (that which makes it possible to determine the current time) and a wheel of the other kinematic chain (that which allows to measure a duration).
  • Lateral or horizontal clutch devices make it possible to couple two wheels by putting them in contact by their periphery (toothing).
  • the disadvantage of this type of clutch is that during the training of the counting wheel of a timed time it is possible to have a jump departure due to misalignment of the teeth of the two wheels.
  • the gap is all the smaller as there are teeth.
  • teeth with many teeth are difficult to manufacture and more prone to wear. In this type of device, there is no movement of oscillation or tilting of the elements of these devices.
  • the document EP2570869 describes a lateral or horizontal clutch device.
