Definitions

  • the invention relates to a striking mechanism of a watch provided with an active damping counter-spring.
  • the mechanism comprises at least one hammer arranged to strike at least one stamp attached to a stamp holder at specific times. Said hammer is kept at a distance from the stamp by said damper counter-spring in a rest mode.
  • a hammer driving spring of the mechanism may be configured as a resilient beam or blade. This drive spring can be armed to drive said hammer against the stamp to acoustically signal for example a programmed period of time.
  • a striking mechanism can be combined with a traditional watch movement to serve in particular for minute repetitions or to signal a programmed alarm time.
  • a striking mechanism generally comprises at least one stamp made of metal material, such as steel, bronze, precious metal, metal glass, sapphire or quartz.
  • This stamp can describe for example at least a portion of a circle around the watch movement in the watch cage.
  • the stamp is fixed by at least one of its ends to a stamp holder, which is itself secured to a watch plate.
  • a hammer mechanism is rotatably mounted on the plate for example near the stamp holder so as to hit the stamp to make it vibrate.
  • the sound produced by the hammer-struck tone is particularly in the audible frequency range from 1 kHz to 20 kHz. This makes it possible to signal to the wearer of the watch, a definite time, a programmed alarm or a minute repetition.
  • the striking mechanism of a watch may include two timbres fixed by one of their ends to a same stamp holder, which is itself secured to a plate. Each stamp may be struck by a respective hammer. To do this, each hammer is driven by a proper drive spring, which had to be previously armed, so as to drive the hammer against the stamp to signal a minute repeater or an alarm time.
  • Two damping counter-springs are each provided for pushing and holding the two hammers away from the stamps in a rest mode. The shock-absorbing counter-springs also slow the fall of each hammer before striking against the respective stamp before pushing it back to the rest position. Eccentrics are also provided for adjusting the operation of the counter-springs to prevent rebound of each hammer against the respective stamp.
  • a disadvantage of such a structure of the striking mechanism with these counter-springs is that there is a significant loss of kinetic energy of the hammer during the striking of the respective stamp, which reduces the acoustic level of the ring. This loss of energy is largely due to the slowdown imposed by each counter-spring on the path of the hammer when it hits the stamp. Moreover, even if the pre-arming of the drive springs is increased, this implies an adaptation of the counter-springs via their eccentric to also avoid any rebound, which is another disadvantage of such a striking mechanism.
  • the invention therefore aims to overcome the disadvantages of the state of the art mentioned above by providing a striking mechanism of a watch, which comprises means for increasing the acoustic level of the sound produced by at least one stamp struck by the minus a hammer avoiding any rebound and any loss of energy from the hammer when striking.
  • the invention relates to a striking mechanism of a watch, which comprises the features defined in the independent claim 1.
  • An advantage of the striking mechanism according to the present invention lies in the fact that it comprises a damper counter-spring considered active, that is to say that when the hammer is struck against the stamp, it acts not directly to push said hammer back to its rest position.
  • the counter-spring can be activated with a certain delay, in particular by means of the driving spring in support of a stop combined with the counter spring.
  • the drive spring can take the form of an elastic metal beam or blade attached to the watch plate and having a free end to push a pin or pin of the rotary hammer when the hammer is struck against the stamp.
  • the hammer is rotated by the drive spring to hit the stamp retaining all the energy of striking without being braked by the counter-spring. This ensures an increase in the acoustic level produced by the struck stamp.
  • the braking of the drive spring in contact with the stop combined with the counter-spring can also intervene after the striking of said hammer against the stamp.
  • the counter-spring pushes the hammer towards its rest position to avoid any rebound of the hammer against the stamp. In the rest mode, the hammer shaft is held trapped between the free end of the drive spring and one end of the spring.
  • the striking mechanism 1 comprises at least one stamp, which is fixed at one of its ends to a stamp holder, which is integral with a plate 15 of shows. The other end of the stamp is usually free of movement.
  • This striking mechanism 1 also comprises at least one hammer rotatably mounted about an axis 7 on the plate, in particular near the stamp holder.
  • the stamp, the stamp holder and the hammer of the striking mechanism 1 are not represented on this figure 1 , because they are on the other side of the plate 15. This allows to easily change the spring elements shown in the figure 1 , if needed.
  • the striking mechanism 1 further comprises a damping counter-spring 5 for holding the hammer 2 away from the bell in a rest mode, and a driving spring 3 of the hammer.
  • This drive spring 3 may be armed by a lift 11 explained hereinafter to drive the hammer 2 in a bell mode against the bell to produce an acoustic sound.
  • the damping counter-spring 5 is defined as active, since it acts on the hammer to return it to its rest position just after the hammer hits the stamp to avoid any energy loss of the hammer in action. This increases the quality of the sound produced.
  • the driving spring 3 of the hammer is fixed at one of its ends 3b in the form of a bead by means of a screw 13 on the watch plate 15. Since this heel 3b, the drive spring 3 has a beam or metal blade, which describes a U shape. This beam 3 surrounds a stop 10, in the form of a lever, which is combined with the damper counter-spring 5 to make the active counter-spring as explained below. This stop plays part of the role of activation means of said counter-spring.
  • This abutment 10 comprises a first branch 12, a free end of which is intended to come into contact with an intermediate portion of the beam of the drive spring 3.
  • the contact of the first branch 12 of this abutment with the intermediate portion of the spring 3 can be performed for example in a portion corresponding to half the length of the beam from its end 3b fixed to the plate 15. In this mode of rest, the intermediate portion of the beam of the drive spring 3 remains in direct contact with this end of the abutment 10.
  • the free end 3a of the beam of the drive spring 3 can be arranged in a rest mode slightly distant from the rod 6 of the not shown hammer.
  • the abutment 10 is combined with the counter-spring 5
  • the first end 5a of this counter-spring is actively driven with the hammer shaft 6 by the abutment 10 against the free end 3a of the driving spring in the operating mode. rest.
  • the hammer is thus kept remote from the stamp by the damping counter-spring 5 bearing against the hammer rod 6, which protrudes from the plate 15 on the side of the spring elements.
  • the damping counter-spring 5 is constituted by a substantially rectilinear lever rotatably mounted about an axis 8 perpendicular to the watch plate 15.
  • a first end 5a of the counter spring lever 5 thus bears against the rod 6 of the hammer to keep it remote from the stamp in a rest mode.
  • a second end 5b of this counter-spring lever 5 is disposed on an opposite side of the first end 5a with respect to the axis of rotation 8.
  • An eccentric part 4 can be rotatably mounted on the plate 15 to serve as a stop rotation of the counter spring lever 5.
  • the first end 5a of the metal counter-spring may bend slightly in the striking mode just after the hammer hits the bell, by the force applied by the driving spring 3 in action as explained hereinafter with reference to Figures 2A to 2E .
  • the first end 5a of the damper counter-spring 5 is momentarily released from the rod 6 of the hammer. This allows the hammer to not lose energy when it is in action for the striking of the stamp.
  • this first end 5a of the counter-spring 5 pushes the hammer with a certain delay towards its rest position after the hammer strike. .
  • the eccentric part 4 is not used in this embodiment to serve in particular as a fulcrum of the counter-spring lever 5 so that it pushes the hammer towards its position of rest after the strike. It could possibly not be present in the striking mechanism.
  • This eccentric part 4 consists of a wheel which can be in contact with a surface of the second end 5b. This wheel of the eccentric part 4 is mounted eccentrically on a rotation pin disposed in a bore of the plate 15.
  • the abutment 10 in the form of a lever, is mounted on the axis of rotation 8 of the counter-spring 5.
  • a screw root is provided for the mounting of the abutment 10 and the counter-spring 5 on the plate 15.
  • This screw foot comprises a disk at its base fixed on the plate 15 and on the disc, a tubular portion smooth on the outside and threaded inside.
  • the counter-spring 5 in the form of a lever is first mounted on the screw base 17 to bear on the disc of the screw foot.
  • the counter spring 5 comprises a through opening at the axis of rotation 8. This through opening has a diameter equivalent to the outer perimeter of the tubular portion to allow mounting the spring against, for example, without play on the tubular part.
  • the stop 10 also comprises a through opening in an intermediate portion 10a.
  • This opening of the abutment is of diameter equivalent to the outer perimeter of the tubular portion of the screw foot 17 to mount the stop without play on the tubular portion above the spring-spring 5.
  • a second eccentric part 14 which is rotatably mounted on the counter spring 5, for adjusting the position of the stop 10 on the counter spring 5.
  • This eccentric part 14 comprises a pin inserted into a bore of equivalent diameter formed on an intermediate portion of the counter-spring 5 between the axis of rotation 8 and the second end 5b of the spring against.
  • the second eccentric part 14 has, above the pin, an eccentric portion placed in another through opening 24 of particular shape at one end 10b of a second branch of the abutment 10. This eccentric portion is in contact with a surface inside the other through opening 24 of the stop. When the second eccentric part 14 is turned, this allows the free end of the first leg 12 of the stop lever 10 to be more or less remote from the stamp.
  • the intermediate portion of the pre-armored training spring 3 returns more or less quickly in contact with the free end of the first leg 12 of the stop lever 10 when the hammer is struck against the stamp. This also has the effect of adapting the action delay of the counter-spring 5 following the first hammer strike against the stamp.
  • the hammer activated by the drive spring in action is propelled quickly against the bell before the drive spring activates the counter-spring by contact on the stop 10 to push the hammer to its rest position.
  • the delay of action of the counter-spring 5 may be of the order of 2 ms depending on the configuration of the spring elements and the hammer, and the materials constituting them.
  • first and second branches of the lever of the abutment 10 are arranged substantially opposite one another, with a perforated portion between the two branches.
  • the rotation of the free end of the first branch 12 and the second branch is on the same side with respect to the axis of rotation 8 of the abutment 10 and the counter-spring 5.
  • the intermediate part of the spring comes into contact of the free end of the first leg 12 of the stop lever 10.
  • the second leg of the stop lever 10 is normally provided to drive the counter-spring 5 so that its first end 5a comes into contact with the hammer rod 6 in the rest mode.
  • This second branch 12 of the lever of the abutment 10 also serves to brake the drive spring 3 in action, while making the damping counter-spring 5 active to pinch the rod 6 of the hammer and bring it back to the rest position. This operation is carried out with a certain delay compared to the striking of the hammer against the stamp.
  • the base of the first leg 12 of the stop lever 10 may be located at the end 10b of the stop, where is disposed the second eccentric part 14.
  • the contact of the end of the first leg 12 of the abutment 10 with the drive spring 3 can be done in a portion closer to the free end 3a of said drive spring.
  • the abutment 10 has instead of a lever, a simple protruding portion. This protruding portion may be made in a single piece between the two through-openings of the abutment to come into contact with the intermediate portion of the drive spring 3.
  • a second eccentric part 14 for adjusting the position of the abutment 10 on the counter-spring 5
  • the preassembly operation of the drive spring 3 can be performed by means of the hammer shaft 6, which is driven by a lift 11 rotatably mounted about an axis of rotation 27 on the plate 15.
  • this lift 11 can also be mounted on the axis of rotation 7 of the hammer.
  • this lift 11 has a tooth 11a activated by a toothed wheel 16 rotatably mounted on the plate.
  • the teeth 16a of this wheel 16 are arranged according to the desired ring repetition.
  • the lift 11 can be turned by this toothed wheel 16 in a ringing mode to arm the drive spring 3 by pushing the rod 6 of the hammer against the free end 3a of the drive spring 3.
  • the damping counter-spring 5 is free to rotate while being limited in rotation by the first eccentric part 4.
  • an initial setting in particular by the second eccentric piece 14 must be made to avoid any rebound when hammering the hammer against the stamp.
  • the impact portion of the hammer may be arranged further from the stamp.
  • the drive spring 3 can be more or less strongly pre-armed with any type of stamp material once the initial setting has been made.
  • the hammer can be made of a hard material, such as tungsten cobalt carbide (WCCo), or a ceramic material or diamond. At least the impact portion 2a of the hammer 2 against the stamp 21 should be made of this hard material.
  • the material of said hammer 2 can also have a high density. This makes it possible to increase the energy during the impact of the hammer against the stamp according to a given typing speed of the hammer. No energy loss during the impact of the hammer is caused by the damping counter-spring 5, since it acts with a certain delay to bring the hammer back to its rest position.
  • This counter spring 5 can also be made of hard metal or steel, as the stop 10, while the drive spring 3 can be made of traditional spring steel.
  • the stamp 21 can be made in the form of at least a portion of a circle or rectangle.
  • the stamp may be for example a wire of circular or rectangular cross section, which is generally steel or precious metal or metal glass. Traditionally, this portion of a circle or rectangle surrounds part of the unrepresented watch movement.
  • the Figure 2A represents only in top view the striking mechanism 1 in a rest mode, as previously described with reference to the figure 1 .
  • the free end 3a of the drive spring 3 and the end 5a of the counter spring 5 pinch the rod 6 of the hammer 2.

  • the impact portion 2a of the hammer 2 remains remote from the stamp 21.
  • the hammer 2 is also kept remote by the counter-spring 5 and the spring 3 training even in case of shock of the watch equipped with this striking mechanism 1.
  • the drive spring 3 is pre-armed at the beginning of the ringing mode as shown in part at figure 2B .
  • the drive spring 3 is dimensioned in such a way as to be able to pre-arm it with a maximum force of the order of 1 N.
  • the preaming operation of the drive spring 3 can be carried out by means of the hammer rod 6 , which is driven by a lift 11 rotatably mounted about an axis of rotation 27 on the plate 15. This lift 11 is rotated by means of its tooth 11a, which is activated by one of the teeth 16a of a wheel. 16 in this position of the pre-armed spring, the impact portion 2a of the hammer 2, which ends in the form of an edge, is even further removed from the stamp 21. In this position, the counter- damping spring 5, as well as the abutment 10, are no longer in contact with the rod 6 of the hammer 2 and the driving spring 3.
  • the impact portion 2a of the hammer 2 strikes the stamp 21, at its highest speed, without being braked by the counter-spring 5, which increases the quality of the sound produced compared to a striking mechanism traditional.
  • the striking time of the hammer 2 against the stamp 21 from the position of the drive spring 3 prealarm may be of the order of 0.2 ms.
  • the drive spring 3 in action and in contact with the abutment 10, activates the damper counter-spring 5 with delay relative to the striking of the stamp 21 by the hammer 2. This delay can be of the order of 2 ms.
