Definitions

  • the present invention relates to a mechanical clock movement provided with power reserve detection means.
  • a power reserve of a mechanical watch movement of a mechanical watch makes it possible to display to a person wearing the watch the operating time before the watch movement stops. It has been observed that the power reserve from one watch to another can vary significantly depending mainly on the manufacturing tolerances of the watch, wear, lubrication, roughness.
  • a mechanical clockwork movement generally comprises a barrel system driving at least one load output wheel and one discharge output wheel connected respectively to a load wheel and a discharge wheel of a differential.
  • a set of wheels connected to an intermediate wheel of the differential controls a power reserve display, but no element of the movement is provided for a movement blocking operation when the power reserve is at zero.
  • the patent EP 0 568 499 B1 describes a power reserve indicating device for a mechanical watch.
  • the indicating device comprises at least one star wheel with an indicating member, which is rotated when the barrel is charged or discharged.
  • the indicating member makes it possible to display the power reserve of the watch. However, nothing is provided to ensure that the movement is blocked when the power reserve approaches zero.
  • the patent CH 698 752 B1 describes a timepiece, which includes a power reserve indicator mechanism. It includes two barrels facing each other and connected by a common shaft, which controls the power reserve display mechanism. However, nothing is provided to ensure that the movement is blocked when the power reserve approaches zero.
  • the patent application CH 710 320 A2 describes a timepiece, which comprises a source of mechanical energy, such as a barrel and a control member in connection with a control device in the watch case.
  • the control device comprises a power reserve wheel pivotally mounted on the frame and connected to the barrel by a differential so that the angular position of the power reserve wheel is a function of the charge level of the barrel.
  • a control cam is pivotally mounted on the same axis as the power reserve wheel.
  • the control cam has a slot extending in an arc of a circle in which is housed a pin secured to the power reserve wheel.
  • a spiral spring is mounted between the power reserve wheel and the cam.
  • a stop device which comprises a stop lever, to block the movement when the power reserve is close to zero.
  • a stop lever to block the movement when the power reserve indicator is at zero.
  • the main aim of the invention is therefore to overcome the drawbacks of the state of the art by proposing a mechanical watch movement equipped with power reserve detection means and capable of directly blocking the operation of the movement, when the power reserve is close to or equal to zero, using a minimum of components to obtain a compact system.
  • the present invention relates to a mechanical watch movement provided with power reserve detection means, which comprises the characteristics of independent claim 1.
  • An advantage of the mechanical watch movement with the power reserve detection means is that an increase in the accuracy of the power reserve indication is achieved.
  • the power reserve detection means are implemented in such a way that the power reserve indication at zero corresponds to the actual stopping of the mechanical watch movement.
  • a control element which may be a wheel or a plate, is preferably directly connected to a wheel of a drive wheel arrangement at the output of the differential to be driven in rotation or in a rectilinear direction.
  • a control element is preferably directly connected to a wheel of a drive wheel arrangement at the output of the differential to be driven in rotation or in a rectilinear direction.
  • the power reserve detection means preferably comprise a control wheel and a rotatably mounted lever. around a lever axis and cooperating with the control wheel so as to determine on the one hand that the barrel is fully charged, and on the other hand that the barrel is substantially completely discharged for the power reserve indication at zero.

  • the control lever comprises a contact element, such as a rod or a pin or a blade inserted into the opening of the control wheel.
  • the axis of the wheel is arranged parallel to the central axis of the barrel system.
  • the opening of the control wheel comprises a first end for determining a 100% power reserve of the barrel and a second end for determining a 0% power reserve of the barrel system.
  • the first and second ends have circular portions.
  • the circular portions at the ends define half of a circle of radius corresponding to half the width of the opening.
  • the power reserve is at 100%, i.e. the barrel system is fully charged, when the rod or pin, or when a complementary rod or complementary pin which may be the central axis of the barrel system between the rod or pin of the lever and the first end, comes into contact with the first end.
  • the power reserve is at zero when the rod or pin or the blade of the lever comes into contact with the second end.
  • the lever pivots around its axis of rotation in such a way as to allow a locking part of the lever to come and block any element of the movement causing the complete and instantaneous stopping of the movement.
  • the lever comprises a locking piece at one end of the lever coming into frictional contact with a peripheral edge of the barrel system cage to block the watch movement.
  • the locking piece is located at an end opposite that of the contact element, which is the inserted rod or pin in the wheel opening.
  • the axis of rotation of the lever is located close to the locking piece and arranged in such a way that in the locking position, rotation of the lever brings the locking piece against the peripheral edge of the barrel system.

  • the essential difference is at the level of the blocking part 15 of the lever 4 which is a tooth capable of coming into the teeth of a peripheral toothed wheel 24 of the cage of the barrel system 2 as the power reserve is at zero to block the movement.
  • the third form of execution represented in Figures 3a, 3b And 3c differ from the other two forms of execution, because it is not a blocking at the level of the cage of the barrel system which takes place when the power reserve is at zero, but a blocking of a 30 serge of a mechanical oscillator. However, the blocking of the movement takes place from the same way as the embodiments described above by the blocking piece 15 in contact with the serge 30. The entire description of these elements will therefore not be repeated.
