Definitions

  • the present invention relates to a timepiece comprising a striking mechanism that can operate at least in a repeater mode, in particular a minute repeater mode, in which it indicates the current time audibly on demand.
  • the repeater mechanisms are powered either by a large striking barrel that the user winds through a winding crown when the energy reserve is exhausted after several rings, or by a small striking barrel which is raised before each ring by means of a lock that the user manipulates to activate the repetition.
  • the repeater mechanism is only part of the striking mechanism, the latter also having, for example, a function of striking on passage (mechanisms known as grand strike or small strike) or alarm (see CH 703635).
  • the striking barrel then constitutes the source of energy for the entire striking mechanism.
  • the second case corresponds to ringing mechanisms which only include a repeater function.
  • a large striking barrel that can be wound by a winding crown requires in practice to provide a display of its energy reserve so that the user can know when to wind it, and the user must remember to check the energy level before activating the repetition.
  • the travel of the bolt depends on the number of strokes to be struck so that the ringing barrel only recharges with the amount of energy necessary to sound the ringing.
  • the bolt stops in fact as soon as an hour feeler comes into contact with an hour snail to take the information of the number of hours to strike, which, by moving an all or nothing, triggers the catch of quarter and minute information by quarter and minute parts coming to feel the quarter and minute snails under the impetus of respective return springs.
  • the bolt acts via a rack on the shaft of the striking barrel to arm the spring housed in the drum of the striking barrel.
  • the striking barrel arbor moves in the opposite direction under the action of the striking barrel spring and, regulated by a speed regulator, causes an hour ratchet and the quarter and quarter parts to wind up. minutes to strike the current time.
  • the rack returns to its rest position at the rhythm imposed by the arbor of the striking barrel.
  • the drum of the striking barrel meanwhile, always remains fixed.
  • the force applied to the hour cochlea is that of the user. If the user exerts excessive force, this may cause breakage or cause the hours cochlea to rotate until the hours feeler stops on the wrong rung, giving false information of the number of strokes to be struck.
  • the present invention aims to provide a repeating timepiece which overcomes, at least in part, the aforementioned drawbacks.
  • a timepiece in particular a wristwatch, a pocket watch, a pendant watch or a clock, comprising a striking mechanism capable of operating at least in a repeat mode, a striking barrel for powering the striking mechanism and a manual control member operable by the user to arm the striking barrel and activate the repeat mode
  • the striking barrel comprising a barrel drum, a barrel arbor and a housed spiral barrel spring in the barrel drum and coupled by its outer end to the barrel drum and by its inner end to the barrel arbor
  • the striking mechanism comprising at least one gong, at least one hammer to strike the at least one gong and an actuating device coupled to a first barrel element constituted by one of the barrel drum and the barrel arbor to actuate the at least one hammer, characterized in that a second barrel element consisting of the other of the barrel drum and the barrel arbor comprises a toothing with which a pawl cooperates, in that the manual control member is arranged to drive a meshing control rack, by means of a one-way clutch
  • the present invention applies just as well to ringing mechanisms having a repetition function combined with a second type of ringing such as an alarm or ringing on passage, as to ringing mechanisms having only a repetition function.
  • the striking barrel can also be wound by a winding crown, the winding by said manual control device, typically a lock, then serving to preserve the power reserve of the second ring type.
  • the winding crown 18 can occupy three axial positions: a pushed position, an intermediate position and a pulled position. In the pushed position, a clockwise rotation of the winding crown 18 winds the basic movement. In the intermediate position, a rotation of the winding crown 18 clockwise or anti-clockwise allows an alarm time to be set. In the pulled out position, a rotation of the winding crown 18 clockwise or anti-clockwise allows the current time to be set (time of the base movement).
  • the selection pusher 20 passes coaxially through the winding crown 18 and is axially movable with respect to the latter. The selection pusher 20 could nevertheless be separated from the winding crown 18.
  • the striking mechanism has a minute repeater operating mode and an operating mode alarm, the passage from one mode to the other being effected by means of the selection button 20.
  • an actuation of the activation lock 22 that is to say a sliding of the activation lock 22 on the periphery of the case 2 between a rest position and an end position , switches the striking mechanism from a selected minute repeater state (block a) to an activated minute repeater state (block b) by triggering the striking of the hours, quarters and minutes of the current time.
  • a selected minute repeater state block a
  • an activated minute repeater state block b
  • an actuation of the activation lock 22 causes the ringing mechanism to pass from a selected alarm state (block c), where the ringing mechanism is inactive, to an activated alarm state (block d), where the striking mechanism waits for the current time to reach a determined alarm time before triggering the striking of the hours, quarters and minutes of said alarm time (block e). Once the alarm time has been sounded, the alarm mechanism returns to its selected alarm state (block c).
  • the basic movement (not shown) is of the traditional type. It is located on the bridge side and comprises a barrel acting as a power source, a going train, an escapement and a balance-spring or other resonator.
  • the basic movement can be supplemented by an automatic winding mechanism arranged to wind the barrel using the energy released by the movements of the wearer of the timepiece.
  • the striking barrel 24 (cf. figures 4, 5, 6 and 10 ) consists of a barrel drum 52 housing a spiral barrel spring 54 and a toothing 56 secured to the barrel drum 52.
  • the barrel drum 52 is traversed, in a free rotation manner, by a barrel arbor 58 to which is attached the inner end of the barrel spring 54, the outer end of the barrel spring 54 being itself coupled to the wall of the barrel drum 52 by a sliding flange 60, as will be explained later.
  • the barrel drum 52 by its teeth 56, meshes with the wheel 104 of a one-way clutch mobile 106 (cf. figures 7 and 8 ).
  • the pinion 108 of the one-way clutch mobile 106 coupled to the wheel 104 by a disengageable pawl system, is engaged with a toothed sector 110 of a control rack 112 operable by the activation lock 22.
  • control 112 is pivotable around a point 114 and has a slot 116 in which a fixed pin 118 is engaged (visible at the figure 27 ) acting as a stop defining two limit positions of the control rack 112, namely a rest position and an end position.
  • a rack return spring 120 acts on the control rack 112 for the maintain in its rest position when it is not actuated by the activation lock 22.
  • the control rack 112 is used to arm the barrel spring 54 via the barrel drum 52.
  • a pawl 122 engaged in the toothing 56 under the action of a pawl return spring 123 prevents the striking barrel 24 from being unwound by the barrel drum 52.
  • the control rack 112 also serves to actuate a winding pawl 124 positioned by a winding pawl spring 126 - the winding pawl 124 and the winding pawl spring 126 are visible in figure 27 - to set the trigger ratchet 64 in motion and thus disengage the trigger pawl 74, more precisely its engagement lug 84, from the teeth of the barrel ratchet 86 by means of the pin 78 carried by the trigger ratchet 64.
  • the wheel 104 and the pinion 108 of the one-way clutch wheel set 106 are integral in rotation in one direction and free in rotation with respect to each other in the other direction.
  • the movement of the control rack 112 by the activation lock 22 rotates the pinion 108 in the direction in which it is integral with the wheel 104.
  • the wheel 104 driven by the pinion 108 in turn drives the barrel drum 52 , which arms the barrel spring 54.
  • each actuation of the activation lock 22 raises the striking barrel 24.
  • control rack 112 is abandoned to the action of its spring 120 and returns to its rest position by rotating pinion 108 but not wheel 104 which, in this sense, is disengaged from pinion 108 and retained by toothing 56 itself retained by pawl 122.
  • the control rack 112 For its drive by the activation lock 22, the control rack 112 comprises an arm 128 that a pin (not shown) carried by the activation lock 22 can push against the action of the rack return spring 120 and against the action of a return spring of the activation lock 22.
  • the activation lock 22 is movable between a rest position where its return spring presses it against an abutment of the box 2 and an end position of race where it bears against the control rack 112 itself at the end of the race against the pin 118 (cf. figure 28 ).
  • the one-way clutch mobile 106 (cf. figure 9 ) is for example as described in the applicant's international patent application no. PCT/IB2020/060506.
  • the wheel 104 comprises an internal toothing 132 with asymmetrical teeth which delimits a housing 134 in which there are a rigid pawl 136, a rigid drive member 138 and an elastic blade 140 connecting the rigid pawl 136 to the rigid drive member 138.
  • the rigid drive member 138 is integral in rotation with the pinion 108.
  • the wheel 104 is mounted loose around the axis 142 of the pinion 108 and is made integral with the pinion 108 in one direction of rotation by the rigid pawl 136 blocked by the rigid drive member 138 against a tooth of the internal toothing 132. In the other direction of rotation, the rigid pawl 136 clicks and thus separates the wheel 104 from the pinion 108 .
  • the striking barrel 24 has a sliding flange 60. It is therefore a barrel which resembles that of self-winding watches, the sliding flange 60 serving to avoid any overtension in the barrel spring 54. Indeed, unlike conventional minute repeater mechanisms where the degree of winding of the striking barrel depends on the number of strokes to be struck, the striking barrel 24 in the present invention is fully wound each time the activation lock is actuated. 22, this in order to guarantee sufficient energy for the maximum number of strokes that the striking mechanism 6 may have to ring according to the alarm time that the user has programmed.
  • This sliding flange 60 is shown in figure 10 . It may comprise protrusions 144 cooperating with corresponding notches made in the wall of the barrel drum 52 to index positions of the sliding flange 60 along said wall between which the sliding flange 60 can slide in the event of overtension of the barrel spring 54.
  • the spindle wheel 62 is kinematically connected to the speed regulator 48 via the ring gear 50, also called the “small gear”, which is a multiplier gear.
  • the speed regulator 48 makes it possible to regulate the speed of rotation of the striking wheel 50 and of the barrel arbor 58.
  • a helix 146 for locking and unlocking the striking wheel 50 is coaxial with and integral with the speed regulator 48.
  • the output torque of the striking wheel 50 is very low, so that a simple tangent contact on the helix 146 suffices to stop the entire striking wheel 50 and the barrel arbor 58. This tangent contact is ensured by a lever propeller stopper 148 when the latter is constrained by a quarter piece 150 as shown in figure 11 .
  • the quarter part 150 comprises on its periphery two series 152, 154 of three teeth.
  • the first series 152 is intended to drive a first raising of the quarters (not represented) raising a small hammer 42 striking a high pitch 46 (cf. figure 11 and 3 ), and the second series 154 is intended to drive a second lifting of the quarters (not represented) raising a large hammer 40 striking a low gong 44.
  • the part of the quarters 150 also has an internal toothing 156 in engagement with the pinion of the part quarters 94.
  • the piece quarters 150 still has a quarters feeler 158. This quarters feeler 158 is arranged to rest on the rungs of a quarters cochlea 160 (cf.
  • the quarter cochlea 160 is coaxial with the floor of the basic movement. In addition, it carries a pin 164 which, at each turn of the roadway, advances a twelve-pointed star 166 carrying a cochlea of hours 168 by one tooth.
  • a cochlea of 170 minutes (cf. figure 14 ) is coaxial with and integral with the roadway. On the rungs of this 170-minute cochlea can come to rest a 172-minute feeler of a 174-minute piece to determine the number of minutes to strike.
  • the minute part 174 is mounted on the same axis 176 as the quarter part 150 and is subjected to the action of a minute part return spring 178.
  • the minute part 174 is provided with a first toothed sector 180 of fourteen teeth intended to cause lifting of the minutes lifting the small hammer 42.
  • the minute part 174 comprises a second toothed sector 182 which cooperates in a traditional manner with a minute hook 184 carried by the quarter part 150 .
  • the function of a surprise is to lengthen the 0 rung of each arm of the minute cochlea when no minute is to strike, in order to prevent the minute feeler from falling untimely on the fourteenth rung of the adjacent branch.
  • the surprise 196 is activated before each striking, when the hour to strike is an hour without a minute to strike or an hour which slightly precedes (typically by one or two minutes) an hour without a minute to strike, by a quarter jumper 204 which shifts it angularly relative to the minutes cochlea 170 against the action of the spring 202. After the ringing, the surprise 196 returns to the rest position.
  • This movement of the quarter jumper 204 has most of the time no effect on the surprise 196 given the angular position of that here, but when the hour to strike is an hour without a minute to strike or an hour which slightly precedes an hour without a minute to strike, the quarter jumper 204 comes into contact with the surprise 196 to offset it angularly with respect to the minute cochlea 170.
  • the quarter jumper 204 is only in the way of the surprise 196 during the striking phase and does not need to be raised every quarters of an hour by the surprise 196 between the moment when the alarm is activated by the actuation of the activation lock 22 and the moment when the current time coincides with the determined alarm time. Energy consumption is thus reduced.
  • the 174 minute coin may be very close to the 170 minute cochlea.
  • the time it takes for the 174 minute coin to fall to the 170 minute cochlea may be too short to allow the 188 hour rack to activate the 196 surprise.
  • the mechanism of chime 6 is provided with a 210 minute blocker arranged to delay the fall of the 174 minute piece until the 196 surprise is activated by the 188 hour rack.
  • the 210 minute blocker is particularly noticeable at the figure 14 . It pivots around a point 212 and its rest position is defined by a pin 214 against which it presses under the action of a return spring 216.
  • a first arm 218 of the minute blocker 210 serves as a stop for a pin 220 carried by the minute piece 174 to stop the minute piece 174 during the fall of the quarter piece 150, the minute piece 174 and the hour rack 188.
  • a second arm 222 of the minute blocker 210 is struck by the pin 206 of the hour rack 188 after the hour rack 188 has let the quarter jumper 204 move towards the surprise 196 to activate it or not according to the hour to strike. This cooperation between the 188 hour rack and the 210 minute blocker raises the 210 minute blocker and releases the 174 minute piece which can thus fall on the 170 minute cochlea to take the information of the number of minutes to ring.
  • the striking mechanism 6 includes (cf. figures 15 to 20 ) a column wheel 224 consisting of a ratchet 226, a stage of columns 228 and a cap 230, these three elements 226, 228, 230 being mounted integrally around a column wheel axis 232.
  • the column wheel 224 is positioned by a jumper 234 cooperating with the ratchet 226. It is controlled by the selection pusher 20 via, successively, an intermediate rocker 236, a control 238 and a control hook 240 (more visible at the figure 36 ) engaged in the teeth of the ratchet 226.
  • the ratchet 226 has twelve teeth and the floor of columns 228 six columns.
  • the active faces RM of the columns of the stage of columns 228 correspond to the minute repeater mode while the voids AL between two columns correspond to the alarm mode.
  • the cap 230 is located in the example illustrated between the ratchet 226 and the stage of columns 228. It has in its lower face, that is to say the face farthest from the stage of columns 228, a recess 242 which surrounds the column wheel axle 232.
  • the two walls which laterally delimit the recess 242 constitute star-shaped cams for the inner wall 244 and of generally polygonal shape for the outer wall 246.
  • the vertices RM of the star and the polygon are aligned angularly with the active faces RM of the columns and also correspond to the minute repeater mode.
  • the zones AL of the hollow 242 between the vertices RM correspond to the alarm mode.
  • Each actuation of the selection pusher 20 moves the column wheel 224 by one ratchet tooth and causes the striking mechanism 6 to pass from one mode of operation to another.
  • the principle of operating mode selection is to allow quarter coin 150 to drop immediately after actuation of activation lock 22 when striking mechanism 6 is in minute repeater mode, to trigger the striking hours, quarters and minutes of the current time, and to prevent the quarters piece 150 from falling beyond an intermediate standby position, until the current time corresponds to the determined alarm time, when the striking mechanism 6 is in the alarm mode.
  • a secondary alarm trigger rocker 248 is used pivoted around a point 250 and which carries at one end a first pin 252 and at the other end a second pin 254 ( figure 20 ) engaged in the recess 242 of the cap 230.
  • On the first pin 252 acts an alarm trigger rocker jumper 256 subjected to the action of a jumper spring 258.
  • the alarm trigger rocker jumper 256 has two inclined surfaces 260, 262 forming an angle between them.
  • the support of the first inclined surface 260 of the alarm trigger rocker jumper 256 on the first pin 252 keeps the second pin 254 bearing against the outer wall 246 of the recess 242 in an RM zone and keeps the first pin 252 out of the gyration path of a stop 264 defined by an extension 266 of the quarter piece 150 - stop 264 which is in an arc of a concentric circle with the quarter piece 150.
  • the quarter piece 150 is free to fall on the quarter cochlea 160 as soon as the activation lock 22 is actuated.
  • the secondary alarm triggering rocker 248 prevents a primary alarm triggering rocker 268 from touching an output cam 270 of an alarm differential 272 , as will be explained later.
  • the purely “alarm” part of the striking mechanism 6 is thus disconnected from the rest of the mechanism 6 and does not induce any energy consumption in the basic movement.
  • the support of the second inclined surface 262 of the alarm trigger rocker jumper 256 on the first pin 252 keeps the latter in the path of gyration of the stop 264 of the quarter piece 150 and therefore prevents the piece from quarters 150 to fall on the quarters 160 cochlea and set off the bell.
  • the quarter piece 150 stops on the first pin 252, which corresponds to the intermediate waiting position mentioned upper. In this position, the second pin 254 is not in contact with either of the two walls 244, 246 of the recess 242 and the secondary alarm trigger rocker 248 is retained by the primary alarm trigger rocker 268 which, here , is in contact with the output cam 270 of the alarm differential 272.
  • the secondary alarm trigger flip-flop 248 For its cooperation with the primary alarm trigger flip-flop 268, the secondary alarm trigger flip-flop 248 is provided with a tab 274.
  • the secondary alarm trigger flip-flop 248 further comprises a finger 276 capable of cooperating with a nut on the roadway 278, coaxial and integral with the roadway of the basic movement, having four notches 280 (cf. figure 21 ) representative of the shifts to ring in the alarm mode.
  • the primary alarm trigger rocker 268 comprises on its periphery two lugs 282, 284 capable of interacting with the lug 274 of the secondary alarm trigger rocker 248 and an arm 286 passing under the output cam 270 of the differential d alarm 272 and whose end is surmounted by a lug 288 arranged to cooperate with this output cam 270.
  • the primary alarm trigger rocker 268 is not pivoted around a physical axis but around a virtual axis by means of a flexible guide 290 suspending it from a fixed base 292.
  • the alarm differential 272 is used to compare the current time to the determined alarm time.
  • Two diametrically opposed notches 294 made in the output cam 270 define two angular positions of the output cam 270 (one per twelve o'clock) in which the current time coincides with the determined alarm time.
  • the high rotational speed of the road relative to the output cam 270 allows the four notches 280 of the road nut 278 to refine the determination of when the alarm sound should be triggered.
  • the 278 pavement nut is indexed to the 170 minute cochlea for a trip one or two minutes before the quarter.
  • the output cam 270 is indexed so that the primary trigger occurs a little before the trigger on the road nut 278.
  • the alarm differential 272 comprises, around a differential axis 296, a programming wheel 298, a programming pinion 300, a satellite wheel 302, an output wheel 304 and the output cam 270 integral with the output wheel 304.
  • the programming wheel and pinion 298, 300 are integral with the differential shaft 296 and their angular position is maintained by a jumper 306 acting on the programming wheel 298.
  • the satellite wheel 302 and the wheel exit 304 are crazy climbs.
  • the satellite wheel 302 carries a satellite 308 which meshes on the one hand with the programming pinion 300 and on the other hand with the output wheel 304.
  • the output wheel 304 and the output cam 270 rotate at the rate of a turn per twenty-four hours.
  • the programming wheel 298 and the satellite wheel 302 are the two inputs of the alarm differential 272. They respectively represent the alarm time programmed by the user and the current time.
  • the satellite wheel 302 is kinematically connected, by two references 310, to the hour wheel 312 of the basic movement, coaxial with the roadway. Traditionally, the hour wheel 312 meshes with a timer pinion 314 and the roadway meshes with a timer wheel 316.
  • An alarm display wheel 318 is mounted coaxially with the hour wheel 312 and the roadway and freely rotatable with respect thereto. This alarm display wheel 318 is kinematically connected to the programming wheel 298 by a reference 320. This alarm display wheel 318 carries the alarm hour hand 16 indicating on the dial 8 the alarm time programmed by the user (cf. figure 1 ) and preferably moving in quarter-hour steps.
  • a locking lever called a "bird" 322 pivotally mounted around a point 324, comprises a first beak 326 which cooperates with a beak 328 of the part quarters 150 in minute repeater mode to prevent the quarters piece 150 from falling as long as the activation lock 22 has not reached the end of its travel (cf. figure 12 ).
  • This characteristic makes it possible to guarantee the smooth running of the sequence by preventing the quarter piece 150, after having been released, from rising under the action of the striking cylinder 24 without having been able to feel the quarter snail 160.
  • a pin 344 carried by the control rack 112 acts on a finger of the bird 322 to make the bird 322 pivot and release the quarters piece 150.
  • the quarters blocker 330 is positioned by the column wheel 224 such that the bird 322 is away from the beak 328 of the quarters piece 150 and cannot retain the quarters piece 150.
  • the function of the bird 322 is indeed filled, in the alarm mode, by the secondary alarm trigger flip-flop 248 and its pin 252.
  • the bird 322 also allows the striking mechanism 6 to return to minute repeater mode when the user actuates the selection pusher 20 while the striking mechanism 6 is in the activated alarm state (transition from the block of to block a to picture 3 ).
  • the quarter piece 150 is blocked by the pin 252 of the secondary alarm trigger rocker 248.
  • a rotation one step of the column wheel 224 caused by the actuation of the selection pusher 20 causes the shift blocker 330 to pivot, which itself actuates the bird 322 so that a second beak 346 of the latter, adjacent to the first beak 326, come and stand in the path of beak 328 of quarter piece 150 (cf.
  • the second beak 346 of the bird 322 retains the quarter piece 150 in a lower position than its high rest position and than its position on the first beak 326 of the bird 322.
  • the quarter piece 150 blocks the propeller 146, and therefore the speed regulator 48 and the barrel shaft 58, via the propeller stop lever 148.
  • the propeller 146 In its intermediate standby position ( alarm activated state) , the propeller 146 is blocked by a leg 348 of the secondary alarm trigger rocker 248.
  • the pin 384 moves relative to the pull tab 366 in one of the two branches of the L-shaped opening 386 during the passage from position 0 to position 1, and vice versa, of the winding crown 18, and in the other branch of the L-shaped opening 386 when passing from position 1 to position 2, and vice versa, of the winding crown 18.
  • the orientation of the L-shaped opening 386 is such that the corrector lever 376 retains its unchanged position between position 0 and position 1 of the winding crown 18 and pivots when the winding crown 18 moves between positions 1 and 2.
  • the quarter piece 150 drops to its intermediate standby position where it abuts against the pin 252 of the secondary alarm trigger rocker 248 ( figure 33 ), allowing the control disk 354 and thus the locking rocker 424, the stop lever 430 and the indicator drive rake 408 to rotate through an angle, thereby causing the display state to change to indicate the alarm activated state.
  • the quarter piece 150 After the alarm time has been reached and the bell has sounded, the quarter piece 150, at the end of the ascent, puts the display back in the selected alarm state. During this movement, the third pin 422 of the control disc 354 raises the secondary alarm trigger rocker 248 to return its pin 252 to the path of the stop 264 of the quarter piece 150. In a variant, it is a expansion 149 (cf. figure 11 ) of the propeller stop lever 148 controlled by the quarter piece 150, and not the pin 422, which raises the secondary alarm trigger rocker 248 after the alarm time has sounded.
  • the angular position of the indicator disk 396 is linked both to the angular position of the column wheel 224 and to the angular position of the quarter piece 150.
  • the column wheel 224 allows passage from the state minute repeater display to selected alarm and the status of selected alarm or activated alarm to minute repeater display. Moving the piece of quarters 150 allows you to switch from the selected alarm display state to activated alarm and, after ringing, to return to return to the selected alarm display state.
  • the blocking device 414 of the display mechanism is also used to fulfill an isolation function preventing a time setting (of the basic movement or of the alarm) when the bell is ringing, in order to avoid breakage in the striking mechanism 6, in particular at the level of the snails 160, 168, 170 and the output cam 270.
  • the blocking rocker 424 comprises a first lug 440 which is out of the way of the time-setting rocker 368 when no bell sounds, that is to say when the quarter piece 150 is in its position at rest or in its intermediate standby position where it retains the control disc 354.
  • the user can then freely pull the winding stem 364 to put it in its intermediate axial position for setting the alarm time ( position 1) or in its drawn axial position for setting the current time (position 2) and set the time.
  • position 1 the intermediate axial position for setting the alarm time
  • position 2 the current time
  • position 2 the current time
  • the control disc 354 and the blocking rocker 424 move into a position where the first lug 440 blocks the time-setting rocker 368 and prevents thus the user to pull the winding stem 364 from the pushed axial winding position (position 0).
  • the quarter part 150 only regains contact with the pin 418 of the control disk 354, thus releasing the time-setting rocker 368, at the end of its ascent.
  • Another isolation function is provided in the striking mechanism 6, which consists of preventing a change in the operating mode ( minute repeater or alarm ) when the bell is ringing, in order to avoid breakage, in particular at the level of the column wheel 224.
  • the blocking rocker 424 does not interact with the control hook 240 when no bell sounds, that is to say when the quarter piece 150 is in its high rest position or in its position intermediate standby where it retains the control disc 354. The user can then freely operate the column wheel 224 via the selection pusher 20.
  • the locking rocker 424 raises the control hook 240 to release it from the toothing of the ratchet 226 of the column wheel 224 and holds the hook of control 240 out of the toothing of the ratchet 226 until the end of the ascent of the quarter piece 150.
  • the interaction between the locking rocker 424 and the control hook 240 is carried out by means of a second leg 442 of the locking rocker 424 and a pin 444 of the control hook 240.
  • the striking mechanism 6 further comprises an isolation device, illustrated in figures 38 and 39 , preventing the selection of the minute repeater / alarm mode when setting the time (of the basic movement or of the alarm), this also in order to avoid breakage, in particular at the level of the link between the rockers primary and secondary alarm trigger 248, 268.
  • This device includes an L-shaped extension 446 (better visible on figures 34 and 35 ) of the pull tab 366 arranged to cooperate with the pin 444 of the control hook 240. When the winding stem 364 is in the axial winding thrust position (position 0, figure 38 ), pull tab 366 and its extension 446 do not interact with pin 444 of control hook 240.
  • winding stem 364 When, on the other hand, winding stem 364 is placed in the intermediate axial position for setting the alarm time (position 1) or in the drawn axial position for setting the current time (position 2), the extension 446 of the pull rod 366 pulls the control hook 240 out of the path of gyration of the ratchet 226 of the column wheel 224 ( figure 39 ). The user can press the selection button 20, but this action will have no effect on the column wheel 224.
  • the striking mechanism 6 includes an isolation device, also illustrated in figures 38 and 39 , making it possible to deactivate the alarm part of the striking mechanism 6 when setting the time (of the basic movement or of the alarm), this also in order to avoid breakage, in particular at the level of the trigger rockers d primary and secondary alarm 248, 268, especially when setting the time backwards.
  • This device comprises a deactivation rocker 448 coaxial with the time setting rocker 368, subjected to the action of a return spring 450 and controlled by the pull tab 366 and a locking lever 452 controlled by the deactivation rocker 448.
