Definitions

  • the invention relates to a striking mechanism provided with a noise isolator arrangement of a stamp for a watch.
  • the striking mechanism generally comprises at least one stamp attached at one end to a stamp holder integral with a platen, and at least one hammer mounted on the platen to strike the stamp in desired ringing periods.
  • the sound isolator arrangement of the patch is configured to prevent any unintended tingling of the tone in a rest mode, in particular following a shock against adjacent components in the watch case.
  • the stamp or stamps used are each constituted by a metal wire generally of circular shape.
  • This wire of each stamp is placed in a plane parallel to the dial of the watch and the plate on which it is mounted.
  • the wire may normally be arranged around a movement in the watch cage.
  • One end of each stamp is fixed, for example by solder, to a stamp holder integral with the plate, which may be unique for all stamps.
  • the other end of each stamp may be generally free.
  • the striking mechanism of the watch includes a hammer actuated at predetermined times.
  • the vibration of the stamp is produced by the impact of the hammer on the stamp near the stamp holder.
  • the hammer usually makes a partial rotation in the plane of the stamp so as to vibrate the stamp in its plane. Part of the vibration of the stamp is transmitted to the plate by the twist of the stamp holder.
  • the stage then vibrates in a plane parallel to the plane of the timbre.
  • the striking mechanism comprises two cathedral type stamps, fixed at one end to a single stamp holder. There is at least one insert between the windings of the stamps, as well as rings regularly distributed on each stamp.
  • an insulator arrangement has the disadvantage of having a multitude of static insulator elements in the watch case, and in close proximity to each stamp, which can create some nuisance in a ring mode of each stamp.
  • all of these noise isolator elements greatly impairs the aesthetics of such a striking mechanism provided with this sound isolator arrangement of each stamp.
  • the invention therefore aims to overcome the disadvantages of the state of the art by providing a striking mechanism of a stamp provided with a sound isolator arrangement of the stamp, which is easy to implement while allowing the tone to vibrate freely in a ringing mode, and preserving all the aesthetics of said striking mechanism.
  • the invention relates to a striking mechanism of a watch cited above, which comprises the features defined in the independent claim 1.
  • An advantage of the striking mechanism provided with the sound insulator arrangement of the patch is that at least one insulator piece can be moved by a drive means to occupy a position near the patch in a rest or remote position of the stamp in a ring mode.
  • the insulator piece is rotatably mounted on a plate of the striking mechanism being driven by the drive means.
  • This insulating piece preferably comprises at least one U-shaped sector for coming into direct contact with an intermediate portion of the patch in a rest mode.
  • the noise isolator arrangement of the stamp also comprises an isolator counterpart for forming with the insulator part a clamp for trapping an intermediate portion of the stamp in a rest mode.
  • an isolator counterpart for forming with the insulator part a clamp for trapping an intermediate portion of the stamp in a rest mode.
  • the insulator part comprises a number of U-shaped sectors corresponding to the number of timbres of the striking mechanism or to the number of windings of the stamp, so that each U-shaped sector comes into contact with the corresponding stamp in a mode of rest.
  • a rod of the counter-piece comes into contact with all the stamps directly opposite the set of U-shaped sectors open towards the outside of the insulator piece.
  • At least the parts in contact with the stamps of the insulator part and the counterpart are made of an elastically deformable plastic material to serve as insulation of the noise of the stamp or stamps.
  • the figures 1 a and 1b show a top view and a side view of the ring mechanism 1 of a watch with an arrangement isolating the noise of the stamps in a rest mode of the mechanism.
  • the essential elements of the striking mechanism 1 are shown with the insulating arrangement of the sound of the stamps 3, 4, 5.
  • the striking mechanism 1 comprises in this embodiment three stamps 3, 4 and 5. Each of these stamps 3, 4 and 5 is connected by one of its ends to a stamp holder 2, which is integral with a plate not shown. This stage is normally below the elements shown in figure 1 a , and above the stamp holder 2 in the figure 1b an inverted side view of the striking mechanism. Preferably, one end of each patch is connected to a single stamp holder 2, although it could have been considered several stamp holder 2. The other end of each stamp is free movement.
  • Stamps can define a portion of a circle, as shown in figure 1 a , in order to surround a watch movement, not shown, which can be mounted on the plate of the striking mechanism 1.
  • This portion of a circle can describe a portion of angle torus included for example between 180 ° or less and 360 ° but preferably close to 330 ° in this embodiment.
  • the three stamps 3, 4 and 5 are mounted one above the other sufficiently spaced from each other and with their portion defining a plane parallel to the dial of the watch and the plate.

  • the second hammer 14 is intended to strike the second stamp 4, while the third hammer 15 is intended to strike the third stamp 5.
  • the hammers In a rest mode, the hammers are held by a spring element not shown at a distance from each stamp.
  • the striking mechanism 1 also includes an isolator arrangement of the sound of the patches, which is driven by a driving means, which generally comprises a set of levers or latches 10, 11, 12, 26 explained hereinafter.
  • the isolator arrangement of the sound of the stamps mainly comprises an insulator piece 6, which is rotatably mounted on the plate.
  • the rotation of this insulator piece is along an axis substantially perpendicular to the plate, but it could also be envisaged that the axis of rotation is not perpendicular to the plane of the plate.
  • Part 16 of this insulator piece 6 is intended to be placed near the stamps in a rest mode as shown in FIGS. figures 1 a and 1b, but preferably in direct contact with the three stamps 3, 4 and 5.
  • This insulator part 6 thus comprises three sectors U-shaped open outwardly of the insulator part and arranged one above the other along the axis of rotation of said part.
  • the spacing between each U-shaped sector corresponds to the spacing between each stamp 3, 4 and 5 to be isolated in the idle mode.

  • This second lever 11 is itself rotated at its second end in a counter-clockwise direction by an arm of a lever 10 in the form of a minute rake. which is operated in a clockwise direction to act on the first and second levers 12 and 11.
  • first lever 12 remains in contact with the second cam 9, there is provided a return spring, not shown, acting in the anti-clockwise direction of the striking mechanism presented in FIG. figure 1 at.
  • Another return spring, not shown, is also provided on the insulator 6, in particular on its axis of rotation, to act in the clockwise direction. Without the action of the second lever 11 and minute rake 10, the restoring force of the spring of the first lever 12 is much stronger than the restoring force of the spring of the insulator part 6 and also of the spring element of the 7.
  • the sound isolating arrangement of the stamps 3, 4 and 5 further comprises an insulator element 24 rotatably mounted on the plate and disposed of diametrically opposed to the insulator part 6 and counter-insulator part 7.
