Definitions

  • the present invention relates to a striking mechanism for a timepiece such as a wristwatch or a pocket watch.
  • the striking mechanism is for example a minute repeater or a grand strike.
  • the present invention relates more particularly to a striking mechanism of the type described in the patent EP 3108307 B1 of the plaintiff, that is to say comprising at least one gong, an actuating device for actuating the gong(s), a striking barrel, a rocker clutch device for coupling the device to actuation to the striking barrel, the lever of the clutch device being arranged to pivot between a first position where the actuating device is coupled to the striking barrel and a second position where the actuating device is decoupled from the striking barrel , and a bell trigger device.
  • the patent EP 3108307 B1 describes two exemplary embodiments for the bell triggering device.
  • a release lever 15 serves as a support for a pin 14 carried by the rocker 6 of the clutch device to retain this rocker.
  • a bell trigger button 15a the trigger lever 15 is pivoted, which releases the rocker 6, which pivots under the action of its return spring to pass from its first to its second position, thus triggering taking information of the number of strokes to ring then raising the rocker 6 to its first position and then the ringing itself.
  • the bell trigger device comprises a trigger lever 124 and a control lever 125 pivotable at respective points 126, 127 which are fixed relative to each other.
  • the lever trigger 124 serves as a support for a pin 121 carried by the rocker, designated here by the reference 110, of the clutch device to retain this rocker.
  • the control lever 125 is controlled by the bell trigger pusher and carries a retractable lip 132 which, when the pusher is actuated, comes into contact with a lip 133 of the trigger lever 124 to pivot the trigger lever 124 and release thus the flip-flop 110.
  • the trigger device there is a risk that too rapid a release of the pusher by the user will cause the trigger lever 15 to come to block against the pin 14 of the rocker before the seesaw has completed its ascent to its first position.
  • the rocker of the clutch device is then prevented from returning to its first position where it would allow the striking barrel to actuate the gong(s) via the actuating device.
  • the mechanism is blocked.
  • the rocker of the clutch device drops back down to its second position even though the bell has not finished ringing. ringing, which restarts the ringing and so on until the energy of the ringing barrel is exhausted. The same phenomenon can occur if the push-button is pressed while the bell is ringing.
  • the triggering device can cause the same type of malfunction as the first exemplary embodiment when the push-button is actuated while the bell is ringing: the bell restarts before it has finished ringing, the phenomenon repeating itself until the energy of the striking barrel is exhausted.
  • This type of malfunction can also occur during very slow actuation of the bell trigger push-piece, during which, because of the retractable spout 132, the trigger device may find itself in an unstable equilibrium position.

  • a second position or disengaged position, of the clutch rocker 6 the clutch pinion 9 does not mesh with the pinion 12 and therefore leaves the ring shaft 11 free to rotate.
  • the clutch rocker 6 is subjected to the action of a return spring 13 which tends to cause it to pivot in the disengagement direction.
  • the clutch rocker 6 carries a pin 14 (cf. figure 2 ) which, when the striking mechanism is in its rest state, is held against a first end of a striking trigger lever 15 by the action of the return spring 13, thus maintaining the clutch rocker 6 in its engaged position.
  • the bell trigger lever 15 In its rest position, the bell trigger lever 15 is held against a surface 1a of the frame 1 by an all-or-nothing return spring 17.
  • the bell trigger lever 15 can be pivoted in the clockwise direction of the figure 2 to release the pin 14 and therefore the clutch rocker 6 by pushing axially a tube 15a which acts on a second end 16 of the striking trigger lever 15.

Another optional difference is that in the present invention the shift feeler 44 and the first clutch control lever 64 are merged and are integral with the shift rake 35, this in order to simplify the mechanism while ensuring good synchronization between the contact of the beak 45 with the shift cam 46 and the actuation of the second clutch control lever 66 by the shift feeler 44.

  • the main body 200 further carries an abutment 207 (visible at figure 13 ), a return spring 208 which tends to hold the retractable spout 206 against the abutment 207 and an actuating pin 209.
  • the abutment 207 is constituted by the wall of an oblong hole in which is engaged a pin 206d carried by the retractable spout 206.

  • the clutch control lever 66 briefly raises the safety member 202 and then lets it fall against its stop 216.
  • the beak 217 of the safety member 202 is engaged in a notch 218 of the lever clutch control 66 and is almost in contact with a beak 219 of the latter.
  • the clutch device is in its engaged state and the 3 striking barrel begins to rotate the 34 hour, 35 quarter and 36 minute rakes in the other direction, opposing the force of their springs of reminder, to ring the bell.
  • the main member 200 and the auxiliary member 201 return to their rest position (cf. figure 10 ).
  • the shift rack 35 puts the safety device 202 back in its high position (cf. figure 6 ).

At some point during the ringing, after the quarter ringing, the beak 64 loses contact with the clutch control lever 66. If the user has released the pusher, the upper part 206a of the retractable beak 206 retains the fork 67 after the contact between the beak 64 and the clutch control lever 66 has been lost, allowing the bell to continue ringing. If the user has still not released the pusher, it is the safety device 202 which retains the clutch control lever 66 after loss of contact between the beak 64 and the clutch control lever 66 , by cooperating with the beak 219.

  • the main member 200 pivots and makes the auxiliary member 201 pivot, but the clutch control lever 66 is retained by the safety member 202, which maintains the rocker 6, 110 of the clutch device in its first position. No malfunction occurs.
  • the main member 200 returns to its rest position and, by cooperating with the inclined end face 67a of the upper tooth of the fork 67, slightly lifts the fork 67 and therefore the pin 14 which allows the auxiliary member 201 to resume its place under the pin 14.
  • the striking mechanism does not malfunction either in the event of very slow actuation of the striking trigger pusher since no position of unstable equilibrium can be obtained thanks in particular to the rigid connection (without retractable nose) between the main organ 200 and the auxiliary member 201.
