Definitions

  • the present invention relates to a watch movement comprising a power source for maintaining the oscillating movement of a mechanical oscillator by means of a finishing gear comprising a regulating device.
  • CH709394 discloses a clockwork comprising a mechanical power source, two control assemblies, each control assembly comprising an exhaust and a regulating member.
  • the watch movement further comprises a torque-sharing device comprising as many elastic members as regulation assemblies with an input connected to the source of mechanical energy, enabling the transmission of the energy produced by the source of power. mechanical energy to the control assemblies.
  • Each regulation assembly is driven by an elastic member provided until the mobile exhaust.
  • the main object of the present invention is to propose an improvement to the mechanisms known from the prior art, by proposing a movement for a timepiece comprising a regulating device whose construction makes it possible to improve chronometry by distributing a constant torque while disturbing the least possible escape.
  • a mechanical clockwork movement comprises a source of mechanical energy, in particular a barrel, driving a regulating member composed of a balance spring, the oscillating movement of which is maintained by the energy source.
  • the movement further comprises a regulating device disposed between the energy source and an exhaust associated with said regulating member, the regulating device comprising an elastic connection arranged to control the escapement.
  • the elastic connection comprises a spiral spring whose one end is connected to the regulating device and the other end is connected to a triggering device arranged in such a way that the triggering device is released periodically by the regulating device.
  • the regulating device comprises a second wheel in kinematic engagement with the work train of the energy supply device, and an escape pinion which connects the seconds wheel to the exhaust.
  • the seconds wheel is connected to the second end of the spiral spring.
  • an additional wheel is carried by the exhaust pinion.
  • the escape pinion meshes with an additional pinion carrying a trigger cam which controls a trigger anchor arranged to periodically release the trigger wheel.
  • the trip cam is integral in rotation with the escape wheel.
  • the trip cam is integral with the escape wheel.
  • the triggering device is arranged to be released by the regulator every second.
  • the regulating device comprises a second elastic connection in the form of a second spiral spring arranged to control a second regulating member.
  • the tripping device controls either the first spiral spring or the second spiral spring.
  • the first spiral spring, the second spiral spring and a wheel of the trigger device are arranged coaxially about an axis.
  • a first triggering device controls a first spiral spring arranged to control a first regulating member.
  • a second triggering device controls a second spiral spring arranged to control a second regulating member.
  • a differential mechanism cooperating with the power source is arranged to supply power to each of the first and second coil springs.
  • a mechanical clockwork movement in particular for a wristwatch, comprises a barrel 1, driving two balance-springs 4, 5.
  • a regulating device 7, 8, 80 is disposed between the barrel 1, and the escapements 2, 3 associated with each of the balance springs 4, 5.
  • the regulating device 7 comprises two spiral springs 8, 80 arranged to control the escapements 2, 3.
  • the first spiral spring 8 is connected to one end 8A (FIG. figure 2 ) to the energy supply device 9, and the other end 8B ( figure 2 ) is connected to the control device 7, 8 arranged in such a way that the energy supply device 9 is periodically released by the triggering device 6, 10, 11, 12, 13.
  • the spiral springs 8, 80 are concentric and only the escapement 2 controls the triggering and resets the two spiral springs 8, 80,
  • the regulation device comprises two coaxial second wheels 7 mounted free on a second pinion 9, only one of the second wheels 7 being visible on said figure 2 .
  • the second wheel 7 cooperates with an escape gear 14 to connect the second wheel 7 to the exhaust 2.
  • the second gear 9 carries a trigger wheel 6 and the inner end 8A of a spiral spring 8
  • the second wheel 7 is mounted free and is connected to the second free end, outer end 8B, of the spiral spring 8.
  • This second wheel 7 meshes with the exhaust pinion 14 which carries the escape wheel 2 and an additional wheel 12.
  • the escape wheel 2 works with an anchor as is usual in a traditional mechanical movement.
  • the additional wheel 12 drives an additional pinion 13 carrying a trigger cam 11 which controls a trigger anchor 10.
  • the control device comprises two second wheels 7 carried by a pinion of seconds 9.
  • the second pinion 9 also carries a trigger wheel 6 and the inner portion 8A of a spiral spring 8.
  • Each of the second wheels 7 is connected to the second free end of the spiral, respectively 8B of the spiral spring 8 and 80B of the spiral spring 80.
  • the trigger wheel 6 controls the rearming of the two spiral springs 8, 80.
  • the energy from the barrel is transmitted to the second pinion 9, integral with the trigger wheel 6 and the inner ends 8A, 80A of the spiral springs 8, 80.
  • the spiral springs 8, 80, pre-armed assembly comprise outer ends 8B, 80B secured to the second wheels 7 each driving a balance spring-balance 4,5.
  • the principle is the same as the mechanism illustrated in figure 1 with the difference that the balance springs 4, 5, in this example, are arranged one above the other.
  • the barrel 1 transmits kinematically the energy to the second pinion 9, secured to the inner ends 8A, 80A of the spiral springs 8, 80.
  • the outer end 80B of the spiral spring 80 integral with a first wheel of the second 7 drives the Exhaust 3 and the sprung balance 5.
  • the outer end 8B of the spiral spring 8, secured to a second second wheel 7 causes the exhaust 2, the additional wheel 12 and the sprung balance 4.
  • the additional wheel 12 leads the additional gear 13 carrying the trip cam 11 which controls the trigger anchor 10.
  • the trigger anchor then releases the trigger wheel 6 integral with the second gear 9.
  • the second spiral spring 80 and the second second wheel 7 give the force to the second balance spring 5 but only one of the two escape mobiles 2, 3 controls the trigger.
  • a first trigger device 6, 10, 11, 12, 13 controls a first spiral spring 8 arranged to control a first balance-spring 4.
  • a second trigger device 6, 10, 11, 12, 13 controls a second spiral spring 80 is arranged to control a second balance-spring 5.
  • a differential mechanism 20 cooperates with the barrel 1 to supply energy to each of the first and second spiral springs 8, 80 via the pinion of second 9.
