Detailed description of the preferred embodiments The invention relates to a watch 1000 or a timepiece 2000, comprising at least one particular striking mechanism 100. Such a timepiece 2000 can be a music box, or include a music box. François LECOULTRE's work "Complicated watches", Editions horlogères, Bienne (Switzerland), 1985, ISBN 2-88 175-000-1, describes in detail the basic mechanisms constituting the striking mechanisms, pages 97 to 205, under different chapters: - ringtones, - antique rehearsal, - modern quarter repeater, - simplified repetition, - half shift repetition, - Breguet half-shift rehearsal, - five minute rehearsal, - minute repeater, - large bell. Unless necessary, these basic mechanisms will not be repeated here in detail, the ringtone specialist will be able to find their constitution in this universal reference work, in particular in the last two chapters cited above. The striking mechanism 100 according to the invention comprises, conventionally, at least one reference mobile 1, and preferably a plurality of reference mobiles 1, comprising the time reference snails and / or stars, and in particular a minute snail, a quarter snail, a 190 hour snail. This ringing mechanism 100 also includes at least one mobile ringing trainer 2, as explained in particular in the chapter "large ringing" of the book "Complicated watches" and visible in particular in Figure 40 of this book. This mobile ringing trainer 2 conventionally comprises a detent röchet 22 and a rack pinion 24. The striking mechanism 100 cooperates with a movement 200, which drives the reference mobile (s) 1, and a particular outlet 3 of which is illustrated in the figures, in the nonlimiting form of a star 130 for triggering the striking by movement, adjusted on a roadway, and having four teeth, so as to be able to lift, every quarter of an hour, an intermediate rocker triggered by movement, hereinafter lifted 70. The striking mechanism 100 includes at least one pivoting part, which is arranged to cooperate indirectly, via this lift 70, with the output 3 of the movement 200, and in particular comprises a feeler for reading such a reference mobile 1 and a rack pinion drive rake 24. One of these pivoting parts is an hour part 20 arranged to cooperate with the hour snail 190. The striking mechanism 100 also includes a main pawl 85, which is arranged to be set in motion during each ring on the way, and to come to drive, when possible, the trigger röchet 22. The ringing mechanism 100 according to the invention comprises all or part of the main ringing modes: large ringing, small ringing, alarm clock, silence, and more particularly comprises a repeating mechanism, in particular a minute repeating mechanism, such as explained in particular in the chapter "minute repeater" in the book "Complicated watches". The non-limiting variant illustrated by the figures includes three ringing modes: large ringing (GS), small ringing (PS), silence (S), and a repetition to minutes. This minute repeater mechanism notably includes an hour piece 20, arranged to cooperate, with a probe 29 which it comprises, with a 190 hour snail. Deactivation of the ringer in silent mode removes the pawls from the ringer trainer mobile 2, and makes it possible to prevent access of the hour piece to the corresponding snail. In particular, the striking mechanism 100 includes a minute repeater with a minute repeater control 4 comprising a repeating pawl 40, which is arranged to drive the detent röchet 22 after a reading performed by said hour piece 20 on the 1909 hour snail. And, in the silence mode, the main arm 64 of the silence rocker 60 authorizes the access of the repeating pawl 40 to the trigger röchet 22, as long as the available energy is sufficient for the 'execution of a complete ring. CH 714 016 A2 In a particular embodiment, the striking mechanism 100 includes a large striking mode for ringing at the passage of each hour, and of each quarter of an hour with the repetition of striking from the hour to the quarter of hour, and a mode of small ringing for the ringing at the passage of each hour, and of each quarter of an hour without the repetition of ringing of the hour to the quarter of hour. The ringing mechanism 100 then comprises a small ringing rocker 80, which is arranged for, when the small ringing mode is selected, orient the small ringing rocker 80 in a position in which the latter prevents the passage of the part of the 20 hours to the 190 hours snail, to prevent the quarter hour strike from striking. When, in this same arrangement, the large ring mode is selected, the small ring flip-flop 80 is oriented in another position in which the latter allows the passage of the 20 hour part towards the 190 hour snail , to authorize the bell to change from hour to quarter hour. To differentiate the ringing at the passage of hours and quarters of an hour, the striking mechanism 100 advantageously comprises, coaxial with a star 130 of four driven by the outlet 3 and which is arranged to trigger the passing of the quarter-rings hour, a tear-shaped hour cam 131, having a tip 132 which is arranged to raise the small striking lever 80, and authorize the passage of the hour piece 20 towards the 190 hour snail. The selection of a particular ringing mode does not hinder the operation of the minute repeater, and in particular in silent mode, except when, advantageously, the ringing mechanism 100 includes a particular stop function arranged to prevent the execution of any ringing if the quantity of available energy is insufficient to ensure its complete execution: the striking mechanism 100 then advantageously comprises a stop mechanism 5, which is arranged to prevent the execution of any ringing, to prevent the risk of stopping certain mobiles in intermediate positions, which may cause collisions during a restart. In the only case where the stop function is efficient, the operation of the minute repeater is also prohibited. This stop mechanism 5 is arranged to rotate a ring reverser rocker 59, especially when the energy available is insufficient for the execution of a complete ring. This ring reversing rocker 59 controls the pivoting of a ring disengaging lever 55, which is arranged to prevent access of the repeating pawl 40 to the trigger röchet 22 when the energy available is insufficient for the execution of a complete ring, and to move the main pawl 85 away from the detent röchet 22 when the available energy is insufficient for the execution of a full ring. Unlike a minute repeater controlled and supplied with energy instantaneously by the action of a user on a pin, a push-button, or the like, the large ring is supplied with energy by an energy reservoir, in particular at minus a barrel, inside the watch. Different energy storage configurations are possible, depending on the volume available inside the watch: a single barrel supplying both the movement and the rings, or a barrel dedicated to the movement and one or more barrels dedicated to the rings, for which energy consumption is always important. The storage device is not detailed here, the drawings show a ringing power reserve indicator output mobile 35, which constitutes the output of a differential mechanism, and said hereinafter more simply known mobile movement 35 of the skilled person. More particularly, this walking mobile 35 comprises several wheels and pinions coaxial and assembled by friction. This walking mobile 35 meshes with a stop wheel 33, which includes an oblong light 34, also called a loop. A stop finger 30 is mounted coaxial with the stop wheel 33, and this finger 30 comprises a stop pin 31, which is movable in a limited manner in the oblong slot 34, and a tip 32. A stopper jumper 36 is positioned opposite this stopper finger 30, it is recalled by a first spring 38, counterclockwise in the figures. In another variant, the stopper jumper 36 can be in one piece with this spring 38. The tip 32 of the stopper finger 30 is arranged to follow a song of this stopper jumper 36. In particular in the variant of the figures, this stopper jumper 36 comprises, at this song, a spout 37, surrounded by a first surface 37A and a second surface 37B, here substantially flat, and which are not aligned (in the nonlimiting example of the figures they make an angle of about 120 ° between them): the path of the tip 32 thus comprises, whatever the direction of this path, an upward slope meeting the torque of a spring, a passage through the spout 37, and a downward slope beyond this spout 37. The stop mechanism 5 further comprises a remote control ring latch 17, which is arranged to control a change in position of the ring release lever 55, during an instant jump of this latch control rocker ringing 17, as soon as the energy level available at said storage means crosses a predefined threshold: in a first direction for disengaging the ringing, when the energy in the storage means is below this threshold, or conversely in the opposite direction to re-authorize the operation of a buzzer, when the energy in the storage means has again become greater than this predefined threshold. This flip-flop control lever 17 comprises, at a first end a fork 19 arranged to surround the locking pin 31, and, under this fork 19, a lug 179, which is arranged to cooperate with a second spring 39, or with a jumper that this second spring controls 39, providing the flip-flop control mechanism 17 with bistable behavior, as will be seen later in the description of the function CH 714 016 A2 ment. Naturally, the second declutching spring 39 can, in a variant, be produced in a single piece with the flip-flop control lever 17. The ringing latch control flip-flop 17 comprises, at a second opposite end, a control arm 18. This remote-controlled arm 18 is supported on a pin 16 which comprises the ringing flip-flop 59, which is itself articulated on a first side with the striking bell release lever 55. The ring reversing rocker 59 is articulated on a second side with a declutching rocker 12, recalled by a declutching spring 13, and cooperating with a pull tab 11 conventionally cooperating with the rod 10 for controlling the setting to the time and winding the watch. Naturally, the declutching spring 13 can, in a variant, be produced in a single piece with the declutching lever 12. The declutching lever 12 advantageously carries an indicator 14, such as a flap visible through a window as visible on the fig. 15, or even such as a needle facing pictograms or the like, or any other suitable display system, intended to very simply warn the operator of the availability or not of the ringtones. Figs. 15 to 32 show the kinematics of the stop mechanism 5, which operates in a reversible manner, FIGS. 33 to 36 illustrating the reverse maneuver. From the initial position of FIG. 15, the walking mobile 35 drives the stop wheel 33, until, as visible in FIG. 19, the oblong slot 34 comes into contact with the locking pin 31, then pivotally driving the locking finger 30, which is in contact with its tip 32 with the first surface 37A of the locking jumper 36, of which is near one of its flanks 30A. The stop finger 30, thus indirectly driven by the walking mobile 35, must overcome the upward slope represented by this first surface 37A and the torque imposed by the first spring 38. After having traversed an angle of approximately 20 °, the tip 32 of the stop finger 30 comes to the top 37 of the slope of the first surface 37A of the stop jumper 36, as visible in FIG. 20. At this stage, the locking pin 31 is not yet in contact with the edge of the fork 19 of the ringing latch control lever 17. The cooperation of the locking finger 30 and the locking jumper 36 makes it possible to bring the locking pin 31 bearing on this fork 19, to control an abrupt pivoting of the ringing latch control lever 17 by instantaneous change of position of a lug 179 which the latter comprises relative to a second spring 39: as soon as the tip 32 of the locking finger 30 has passed the top 37, and comes into contact with the second surface 37B of the jumper stop 36, the stop pin 31 comes into contact with the edge of the fork 19. The second spring 39 has a tip 390 which passes from one side to the other of the lug 179 of the control rocker ringing latch 17, the second spring 39 of which thus causes it to overturn. This second spring 39 thus constitutes a ring lock control jumper, which is arranged to constrain the fork 19 of the ring lock control rocker 17 in pressing on a star 7, preferably one on each side of the fork 19, or on a limiting wall, in each of the two positions that the buoyancy control lever 17 can occupy, giving it its bistable character. The stop finger 30 travels about an additional 20 ° before arriving in the final stop position of FIG. 29, where the locking pin 31 is supported on the other end of the fork 19, the second side 30B of the locking finger 30 being in contact with the second surface 37B of the locking jumper 36. In this final position the fork 19 bears against the label 7. The trigger thus produced is instantaneous, and provides total security. The function operates in both directions of travel. The invention makes it possible to carry out a stop in big ring mode, when the stop function and the big ring mode exist. The same is true for the small ring mode and the silent mode. This striking mechanism 100 is first exposed without a stop mechanism. Figs. 1 and 2 show the small bell position, which rings the peak hours on the way, and the quarter-hours alone on the way. The usual quarter piece and snail of the quarter are not shown, in order to simplify the description of the operation. The star 130, arranged near the mobiles of the references 1, is arranged to come to cooperate, every quarter of an hour, with a spout 72, in particular elastic, that includes the lifting 70 for triggering ringing, which pivots in a pivot 73. This part of the hours 20 includes a feeler 29 arranged to palpate a snail of the hours 190, and a rake 25 arranged to cooperate with a rack pinion 24 which comprises a mobile ringing trainer 2. This part of the hours 20 also comprises , set back with respect to the probe 29, a rib 23 separating the oblong opening 26 from an interior clearance 28, and this rib 23 is terminated, on the same side as the probe 29, by a flat plate 27 of abutment support. The mobile ringing trainer 2 comprises, for its part, in a conventional manner, a detent röchet 22, with which is arranged to cooperate, or else a main ringing pawl 85, or else a minute repeating trigger pawl 40 , provided with a pin 41, and that includes a minute repeat command 4, where the latter pawl 40 cooperates with a spring 43. CH 714 016 A2 The pivoting of the ringing trigger lifting 70 causes the pivoting of a trigger rocker 50 by movement, which carries a thrust spring 52 which bears on the main ringing pawl 85, that also carries the trigger lever 50. A small ring flip-flop 80 of conventional type carries a stop pin 82. This small ring flip-flop 80, recalled by a declutching spring 83 fixed to a plate, comprises a declutching spout 81, which is arranged to take pressing on a cam pin 97, which comprises a mode selection cam 90, which comprises a mode selector mechanism 9. The small striking lever 80 faces the hour piece 20 during the angular travel of the latter, and the stop pin 82 is at the rib 23 of the hour piece 20, on the same radius, which allows it to cooperate in abutment support with the dish 27 of the hour piece 20, and to immobilize the latter by preventing it from reaching the 1901 snail, so as not to repeat the striking of the hours on each shift, depending on the operation specific to the small bell mode. In order to ensure the striking of the hour at the full hour, the star 130 is integral with a tear-shaped hour cam 131, the tip 132 of which is arranged to lift the small scale. buzzer 80, and therefore its stop pin 82, to allow passage to the feeler 29 of the hour piece 20 for reading on the 1901 hour snail. [0056] FIGS. 3 and 4 show the large bell position, which sounds the peak hours on the way, and both the hour and the quarter-hour on the way. The usual quarter piece and snail of the quarter are not shown. The support of the cam pin 97 on the small striking lever 80 is made at a greater distance from the end of the declutching spout 81 than in the case of the small striking, and therefore the stop pin 82 n '' is no longer at the rib 23, nor at the flat 27 of the hour piece 20, but is at the level of the clearance 28, which allows the 20 hour pieces to pivot freely towards the 190 hour snail each quarter time. For operation in silent mode, the ringing mechanism 100 includes a large ringing and small ringing isolator, hereinafter referred to as a silence flip-flop 60. This silence flip-flop 60 has at one end a readout spout 61 arranged to cooperate with one of the peripheral zones 98 of the mode selection cam 90, and at a second end 62 a main arm 64, which is arranged to stop a main pawl pin 86, which comprises the main ringing pawl 85. This silence rocker 60 has, in its middle part near its pivot, a silence pin 63. The spring 65 constrains the silence rocker 60 by means of the pin 63, for this rocker is always in contact with the cam 90 by its spout 61. When the selected mode is silent mode, this silence rocker 60 pivots and its part 62 disconnects the pawl 85 from the röchet 22. The cam pin 97 is in contact with the declutching spout 81 of the small ring latch 80. During a minute repeater (in small ring mode), a rocker not shown in the figures makes the link between the control 4 and the rocker light 80, so that the rake for hours 20 can fall on the snail of hours 190 in room 1. This silence flip-flop 60 is visible in FIGS. 5 to 11, which comprise the stopping mechanism 5, which essentially comprises a striking bell release lever 55. The striking mechanism 100 thus comprises, partially superimposed, the silence rocker 60 and the striking bell release lever 55, which are each arranged to obstruct the access of a particular pawl to the röchet 22 of the striking ringing mobile 2. In effect, the ringing disengaging lever 55 comprises a stop arm 56, which is arranged to stop a pawl pin 41, which includes a minute repeat trigger 40, of the minute repeat 4. The figures show the particular arrangement of the main pawl 85 and the minute repeating trigger pawl 40, which are both located on the same side of the ringing drive mobile 2 and its röchet 22, between the cam mode selection 90 and this röchet 22. This arrangement is particularly favorable, due to a particularly reduced volume, short distances between the various components, allowing the use of more rigid rockers, and it allows the design of a a compact, reliable and efficient stop mechanism. This arrangement is made possible in particular by placing the trigger rocker 50 between the lift 70 or first ring trigger rocker, and the main pawl 85: this trigger rocker 50 supports the articulation of this main pawl 85, and comprises the spring 52 which pushes on this pawl; it allows the positioning of the main pawl 85 on the same side as the minute repeating trigger pawl 40 relative to the röchet 22, it reverses the pivoting direction of the main pawl 85 compared to a standard assembly where the latter would be in direct contact with lifting 70, and above all generating energy savings by precisely managing the engagements and exits of the spout of the main pawl 85 relative to the röchet 22. In particular, the main pawl 85 and the minute repeating trigger pawl 40 are substantially aligned thanks to this new arrangement, and the silence rocker 60 and the striking bell release lever 55 can be superimposed, almost collinearly, which considerably simplifies the control and stopping of the rings, reducing the number components and the operating strokes of these components. Figs. 5 and 6 show the position of the silent mode, in which the small and large rings are disengaged, but where the operation of the minute repeater is authorized. The reading spout 61 of the silence rocker 60 is supported on the largest radius 98S of a peripheral range 98 of the cam 90, and, therefore, on the one hand the rocker CH 714 016 A2 small bell 80 is stopped by the cam pin 97 and the spring 67 and, on the other hand, the main arm 64 of the silence rocker 60, visible in FIG. 11, is in its position furthest from the striking bell driving mobile 2, and stops the main pawl pin 86. On the other hand, the striking bell disengaging lever 55 is very close to the striking bell driving mobile 2, since nothing happens opposes this extreme position, and therefore the trigger for repeating the minute repeater 40 is not hindered and can access the trigger röchet 22, and the minute repeater can therefore be launched at will by the user. When the stop mechanism 5 enters into operation, when the energy available is insufficient to ensure normal and complete execution of a buzzer, and therefore with a return of all the components to the rest position after at the end of the ringing game, the ringing latch control lever 17 suddenly pivots, causing the ringing lever 59 to pivot by its pin 16. The ringing lever 59 is articulated with the lever striking bell disengaging 55, which it immediately moves away from the striking mobile 2, so as to also move the main pawl 85 and the minute repeating trigger pawl 40 away from it, thus preventing any ringing being carried out. When the user reloads the barrel (s), he operates the rod 10: the position T1 conventionally corresponds, in a first direction, to the recharging of the movement barrel and in the other direction, to the recharging of the barrel bell, position T2 being reserved for setting the time of the watch. When the user reloads the barrel (s), it is only when the energy level has become sufficient that the flip-flop control flip-flop 17 can perform the reverse jump, thereby causing flip-flop d ring reversal 59 and tilting of the bell disengaging lever 55 to authorize the rings. The user must wind the barrel a certain number of turns, in order to guarantee a minimum of ringing. To this end, the winding train comprises one or more barrels cooperating with at least one röchet and a differential mechanism, in particular comprising a friction, and, the adjustment of which defines the predefined threshold at which the stopping or the release is triggered in the 'other way. The release of the clutch lever is instantaneous. When the user sets the time to the watch, the passage in position T2 of the rod 10 causes the pulling rod 11 to pivot, disengages the disengaging lever 12, then causing the reversing lever to strike 59 and the tilting of the strike disengaging lever 55. The latter comprises the stop arm 56 which disengages the repeating pawl 41 and the main striking pawl 85. This mechanism thus allows the user to make a setting the time in both directions safely, since no ringing is then possible. The combination of this mechanism with the stop mechanism thus constitutes an improvement favorable to the operating safety of the watch in all circumstances. The stop mechanism is coupled to that of disengaging the pawls in position T2. These safety mechanisms use the same components to disengage the bell reversing rocker 59 and bell disengaging lever 55), but these mechanisms operate independently of each other. Figs. 7 and 8 illustrate the stop in big ring mode. The stop mechanism 5 is arranged to disengage all the pawls, when the quantity of energy available, at the level of the barrel (s) or the like, is insufficient. This time, the reading spout 61 of the silence rocker 60 is supported on the smallest radius 98AGS of the peripheral range 98 of the cam 90, and, at its second end 62 the main arm 64 of the silence rocker 60 is in its position closest to the striking buoy 2, and cannot stop the main pawl pin 86. On the other hand, the striking clutch release lever 55 is in its position farthest from the striking buoy 2, and thereby hinders both the main pin 86 of the main pawl 85 and the repeating pawl pin 41, therefore the main pawl 85 and the minute repeating trigger pawl 40 are hindered and cannot access the detent röchet 22 The minute repeater cannot be activated by the user. No ring can therefore be launched. Nothing stands in the way of another fashion selection maneuver. Figs. 9 to 11 illustrate stopping in silent mode. These figures show the ring reversing rocker 59 for the articulated control of the ring disengaging lever 55. The reading spout 61 of the silence rocker 60 is supported on the largest radius 98S of the peripheral range 98 of the cam 90, and the main arm 64 of the silence rocker 60 is in its position furthest from the striking bell mobile 2, and stops the main pawl pin 86. The striking bell release lever 55 is also in its position the further from the striking bell mobile 2, and hinders the repeating pawl pin 41.
