Definitions

  • the present invention relates to a timepiece movement intended to be placed in a case of a timepiece.
  • It also relates to a balance-spring assembly for a timepiece as well as a balance for such a timepiece.
  • the present invention further relates to a timepiece comprising such a timepiece movement, such a balance-spring assembly or such a balance.
  • Many conventional mechanical watch movements include a regulating member produced in the form of a balance-spring assembly, this assembly being formed of a balance and a spiral spring.
  • Conventional pendulums are formed by a serge, a pendulum axis and arms connecting the serge to the pendulum axis.
  • the arms and the serge are in the same plane.
  • the spiral spring is generally arranged in a plane, parallel to the plane of the twill and the arms.
  • the spiral spring may have a cylindrical, conical or spherical shape.
  • the center of gravity of the balance-spring assembly is also in the same plane, on the axis of rotation of the balance .
  • the present invention proposes to produce a balance and a balance-spring assembly such that the center of gravity of the balance-spring assembly can be adjusted along the axis of rotation of the balance.
  • a timepiece movement comprising an energy source, a gear train, a distribution mechanism and a regulation mechanism produced in the form of a balance-spring balance, this balance-spring assembly being formed of a balance and a spiral spring, the balance comprising a serge and arms connecting the serge to a balance axis, this clockwork movement being characterized in that at least part of the arms form a curve not coplanar with the pendulum serge.
  • a balance-spring assembly for a timepiece, this balance-spring assembly comprising a balance comprising a serge and arms connecting the serge to a balance axis, this balance-spring assembly further comprising a spiral spring, the balance-spring assembly being characterized in that at least part of the arms form a non-coplanar curve with the balance of the balance.
  • a pendulum for a timepiece comprising a serge and arms connecting the serge to a pendulum axis, characterized in that at least part of the arms form a curve not coplanar with the pendulum serge.
  • a timepiece comprising a movement, a balance-spring assembly and / or a balance wheel as defined above.
  • a spiral spring having an outer envelope of different shapes, for example a cylindrical, conical or portion of a sphere. It is also possible to use a planar spiral spring or other shapes, or even combinations of these different shapes, on different parts of the spiral spring.
  • the shape of the balance, the shape of the balance spring and the possibility of choosing the fixing position of the balance spring makes it possible to adjust the position of the center of gravity of the balance-spring assembly.
  • the timepiece movement according to the present invention is intended to be placed in a case (not shown) of a timepiece such as in particular a watch of the wristwatch type.
  • a timepiece such as in particular a watch of the wristwatch type.
  • Such a timepiece conventionally comprises a plate supporting in particular a motor system having a power source, and a cog formed of gears driven in rotation by the motor system.
  • the plate further supports a regulating member produced in the form of a balance-spring 10, this balance-spring 10 assembly being illustrated by the figures 1 to 4 .
  • the balance-spring assembly 10 comprises a balance 11 on the one hand and a spiral spring 12 on the other hand.
  • the balance 11 is formed by a clamp 13, a balance pin 14 and arms 15 connecting the clamp 13 to the balance axis 14. In operation, the balance 11 alternately pivots around the balance axis 14, under the effect of the spiral spring 12.
  • the arms 15 of the pendulum 11 are fixed to the pendulum axis 14. This fixing can be done by means of a fixed link such as riveting.
  • the arms 15 can also be driven out on the balance axis 14 or be fixed by means of a ring 16 screwed onto the balance axis 14.
  • the arms 15 are not planar and arranged in a plane in which the serge 13 is located. These arms 15 have a curved or arcuate shape and are fixed to the pendulum axis 14 in an area outside the plane of the serge 13. This arched shape of the arms 15 makes it possible to define a housing limited by an envelope formed by the arms 15 and by the plane in which the serge 13 is placed.
  • One end 17 of the spiral spring 12 is fixed to the pendulum axis 14, as mentioned previously. This fixing is made inside the housing defined by the arms 15 and the twill 13.
  • Another end 18 of the spiral spring 12 is fixed to a cock (not shown) by means of a stud, in a conventional manner.
  • the housing defined by the envelope of the arms 15 and the serge 13 makes it possible to receive a spiral spring 12 having a cylindrical or spherical shape in particular.
  • the balance-spring assembly 10 can thus be easily adapted or modified to choose the position of the center of gravity of this assembly.
  • the latter also has a particular aesthetic aspect, original and attractive.
