Definitions

  • the present invention relates to a striking mechanism, in particular for a timepiece, for example of the minute repeater type or ringing in passing or on demand.
  • a striking mechanism in particular for a timepiece, for example of the minute repeater type or ringing in passing or on demand.
  • each stamp is associated with a hammer so that the sound produced is a note for each strike.
  • the invention also relates to timepieces equipped with a striking mechanism, that is to say a mechanism that makes it possible to strike simultaneously several tonal pitch timbres chosen so as to produce sounds composed of harmonic notes allowing the generation of chords by the simultaneous striking of two, three, four or five stamps.
  • the object of the present invention is to provide a harmonic ringing mechanism that is to say that can for a strike to produce a chord of two, three or more notes of choice to have a more harmonious and richer result.
  • the present invention proposes to make a harmonic ringing mechanism, where several stamps are struck simultaneously with precision while ensuring a given energy transmission to each stamp.
  • the subject of the present invention is a minute repetition or on-demand bell ringing mechanism comprising a group of two or more timbres each struck simultaneously by a hammer and in which a single trigger mechanism operates all the hammers.
  • the present invention also relates to a timepiece comprising such a striking mechanism.
  • the harmonic striking mechanism suitable for being integrated into a timepiece, in particular a wristwatch comprises a group of coaxial stamps of two or more stamps, generally three or four, each comprising a heel 1a, 1b, 1c fixed to the 2 using screws on a fixed part of the timepiece such as a platinum or middle case for example.
  • Each stamp comprises a vibrating member 3a, 3b, 3c extending in parallel planes preferably and following concentric circular arcs superimposed and same radii.
  • the vibrating member of the stamps could be rectilinear or have another shape. It is simply necessary that at least one point of the inner surface of each stamp is disposed on a first straight line 4 preferably perpendicular to the plane of the stamps. These aligned points of the stamps constitute for each stamp the point of strike where the corresponding hammer will strike the stamp.
  • the striking mechanism further comprises a group of hammers, a hammer 5a, 5b, 5c for each stamp, pivoted about a common axis 6 on a ring plate 7.
  • each hammer 5a, 5b, 5c is rotated crazy on the common axis 6 and is held axially to be located in the plane of the corresponding stamp.
  • Each hammer 5a, 5b, 5c has a hammer 8a, 8b, 8c respectively intended to come into contact with the corresponding vibrating member 3a, 3b, 3c when striking.
  • strikers 8 are aligned on a second straight line 4 ', parallel to the first straight line 4, and strike the corresponding vibrating members at the level of the first straight line 4 where the surfaces of the vibrating members 3a, 3b, 3c are located in a same plan. In this way it is ensured that the stroke of each hammer 5a, 5b, 5c during the striking is identical, which ensures the simultaneity of the striking of all the vibrating members and a well-determined energy transfer to each of them. Indeed this amount of energy transmitted to each vibrating member depends on the mass and the speed of the corresponding hammer.
  • each hammer comprises a movable head pivotally mounted on a support itself pivoted on the common axis 6.
  • a spring 9a, 9b, 9c tends to keep each hammer head in the rest position.
  • the hammers can be monobloc, directly rotated on the common axis 6.
  • All the hammers 5a, 5b, 5c are connected together by a connecting pin 10 so that the hammers are integral and can move in rotation about the common axis 6 that all together.
  • a hammer spring 11 secured to the ring plate 7 bears on the connecting pin 10 and tends to move all the hammers 5 towards the vibrating members 3 and maintains these hammers in support on a stop 12 integral with the ring plate 7.
  • One of the hammers here the upper hammer 5a, comprises a lift 13 cooperating with a winding wheel 14 to wolf teeth driven in stepwise rotation in a traditional manner by a control mechanism, here a pusher 15 and a rocker 16 pivoted on the ring plate 7 whose free end includes a hook 17 cooperating with the winding wheel 14.
  • a control mechanism here a pusher 15 and a rocker 16 pivoted on the ring plate 7 whose free end includes a hook 17 cooperating with the winding wheel 14.
  • the triggering of the hammers is absolutely simultaneous, their speed and their stroke are exactly the same, so that the striking of the vibrating members occurs exactly simultaneously and the energy which is transmitted to each vibrating organ depends only on the mass of each hammer. , which can be easily adjusted to the manufacture of the mechanism.
  • the described example of the striking mechanism uses hammers as described in the patent application EP 2 048 548 of the depositor which represents a preferred embodiment but this harmonic ringing mechanism can be equipped with all conventional hammers when they are secured to each other and controlled by the same trigger mechanism.
  • the arming wheel 14 may be driven step by step by any ringing mechanism different from the manual one described by way of example above.
  • the number of stamps is at least two but could be three to five or more depending on the applications.
  • the hammers 8 of all the hammers are aligned on a second straight line 4 'and arranged in planes corresponding to the plans of the stamps.
  • the hammers may be identical to each other if the same amount of energy is to be delivered to each patch. Alternatively the mass of the hammers may be different from one hammer to another depending on the energy to be transmitted to each of the stamps.
  • the timbres are arranged in the timepiece so that their vibrating members are preferably located in parallel planes and at least one point, the striking point, of each vibrating member is located on a first straight line 4 preferably perpendicular to the planes of the vibrating members. These striking points of the vibrating members are thus aligned and can be struck simultaneously by the corresponding jaws of the hammers, these jaws being aligned on a second straight line 4 'parallel to the first straight line 4 on which said strike points are aligned.
