Description

Field of the invention

The invention relates to a striking mechanism or timepiece, in particular a watch, comprising a movement, said striking mechanism comprising at least one reference mobile arranged to be driven by said movement and of which at least one is said reference mobile is an hour cochlea, at least one striking driving mobile comprising a detent ratchet and a rack pinion, said striking mechanism comprising at least one pivoting part arranged to cooperate indirectly with an output of said movement, comprising a feeler for reading said reference mobile and a drive rack for said rack pinion, one of said pivoting parts being an hour part arranged to cooperate with said hour cochlea, said striking mechanism further comprising a main pawl arranged to be set in motion each time the bell passes and drive said trigger ratchet, and said striking mechanism being capable of operating according to at least two distinct ringing modes including a silent mode.

[0002] A timepiece, in particular a watch, may comprise a movement comprising a ringing trigger output on passage through the movement, this movement being arranged to drive at least one reference mobile, and the timepiece comprises at least one such striking mechanism.

The invention relates to the field of striking mechanisms for watches, timepieces or music boxes.

Background of the invention

[0004] Clockwork striking mechanisms are grand complications, complex as much by the number and complexity of the kinematics of their components, as by the modes of operation of which they are capable. The selection among different ringing modes is in itself an additional complication, which implements expensive components, such as column wheels or the like, and which consumes a considerable volume inside the case of the watch or the timepiece, case which often has notches for this selection function. The interface between the selection mechanism and the exterior of the box must, again, benefit from a particular seal. Security management between the different modes is always tricky. For watches with additional complications such as a minute repeater, security management is very complex, and it is difficult to block passing bells to let a minute repeater play, or conversely to block the launch of a repeater minutes when a passing chime approaches, to prevent a minute repeater from being restarted when a repeat cycle has just been launched, to prevent a timer setting while a chime is running, or other, these safeties generally implement a fairly large number of insulators, which further complicates the mechanism and the risks of interference.

Summary of the invention

The invention proposes to carry out the selection of ringing modes in a simple and reliable manner, and compatible with the establishment of effective securities and of average complexity.

To this end, the invention relates to a striking mechanism according to claim 1.

[0007] A timepiece, in particular a watch, may comprise a movement comprising a trigger output comprising a chime as it passes through the movement, this movement being arranged to drive at least one reference mobile, and the timepiece includes at least one such striking mechanism.

Detailed Description of 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 comprise a music box.

[0010] François LECOULTRE's work "Les montres complexes", Editions horlogères, Bienne (Switzerland), 1985, ISBN 2-88175-000-1, describes in detail the basic mechanisms constituting striking mechanisms, on pages 97 to 205, under different chapters: – chimes, – antique repeater, – modern quarter repeater, – simplified repeater, – half-quarter repeater, – Breguet half-quarter repeater, – five-minute repeater, – minute repeater, – large alarm.

The striking mechanism 100 according to the invention comprises, in a conventional manner, at least one reference mobile 1, and preferably a plurality of reference mobiles 1, comprising the snails and/or time reference stars, and in particular a minute cochlea, a quarter cochlea, a 190 hour cochlea.

This ringing mechanism 100 also includes at least one mobile ringing trainer 2, as set out in particular in the chapter "Grande Sonnerie" of the book "Les Montres Complicates" and visible in particular in Figure 40 of this book. This ring trainer mobile 2 conventionally comprises a trigger ratchet 22 and a rack pinion 24.

The ringing mechanism 100 cooperates with a movement 200, which drives the reference mobile(s) 1, and of which a particular output 3 is illustrated in the figures, in the non-limiting form of a ringing trigger star 130 by the movement, adjusted on a roadway, and comprising four teeth, so as to be able to raise, every quarter of an hour, an intermediate rocker for triggering by the movement, hereinafter referred to as lifting 70.

The striking mechanism 100 comprises 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 sensor for reading such a reference mobile 1 and a drive rack for the rack pinion 24. One of these pivoting parts is an hour part 20 arranged to cooperate with the hour cochlea 190. The striking mechanism 100 also comprises a main pawl 85, which is arranged to be set in motion during each ringing in passing, and to drive, when possible, the trigger ratchet 22.

The striking mechanism 100 according to the invention comprises all or part of the main striking modes: grand ringing, small ringing, alarm clock, silence, and more particularly comprises a repeater mechanism, in particular a minute repeater mechanism, such as explained in particular in the chapter „minute repeater“ of the book „Les montres complexes“.

[0016] The non-limiting variant illustrated by the figures comprises three ringing modes: large ringtone (GS), small ringtone (PS), silence (S), and a minute repeater. This minute repeater mechanism comprises in particular an hour part 20, arranged to cooperate, with a feeler 29 that it comprises, with an hour cochlea 190.

According to the invention, the ringing mechanism 100 includes a mode selector mechanism 9. This mode selector mechanism 9 includes a selector 96 accessible to the user to allow him to choose the ringing mode to use, and which controls the angular position of at least one cam 90.

The mode selector mechanism 9 comprises at least one cam 90, which can comprise as many specific positions as there are modes attributable to the striking mechanism as in the variant illustrated by the figures, or which comprises positions specific to only certain of these modes. The variant illustrated represents a flat cam 90, which has three notches each corresponding to one of the selectable modes: 93 small ringtone, 94 large ringtone, 95 silence. More particularly, the notches correspond to notches of variable amplitude, requiring an increasing force in one of the two operating directions. More particularly, a particular notch, for example a notch in the center, is greater than those at the end, so as to ensure safety by preventing the user from switching unexpectedly from one ringing mode to another.

The cam 90 occupies particular positions for the different modes. This cam 90 comprises a continuous outer profile 98 for supporting the probe, which is arranged to cooperate with a beak 61 which comprises a silence rocker 60. This outer profile 98 comprises a zone of greater radius 98S corresponding to the silence mode, which is arranged to orient the silence rocker 60 in a position where a main arm 64 of the silence rocker 60 moves the main pawl 85 away from the trigger ratchet 22, to ensure the deactivation of any ringing in passing, in silent mode.

It is understood that the invention lends itself to the selection of an even greater number of distinct modes, in particular when it comes to differentiating the playing of different melodies, which can for example be used to differentiate the quarters sounded, or the set of different stamps, as in the patent EP2947523B1 of the same applicant, to integrate an alarm mechanism according to the application EP15190808.4 of the same applicant, a security mechanism for selecting and/or ringing or melody triggering according to the application EP15168700.1 by the same applicant, a disengageable lifting melody selection mechanism according to application EP15183110.4 by the same applicant, or even a chime according to application EP16206572.6 by the same applicant.

The cam 90 can thus have multiple notches: GS melody A, GS melody B, PS melody A, PS melody B, S, and/or even: GS stamp A, GS stamp B, PS stamp A, PS stamp B, S. When the modes to be differentiated are too numerous for a single cam, the mode selector mechanism 9 can comprise a plurality of cams 90, in particular superimposed, each of them being able to relate to some of these modes, for example with a melody particular, or a particular timbre, or whatever.

[0022] Such an arrangement makes it possible, in particular, to distinguish the ringing modes by the melodies played, and/or by the timbres used. For example, the big ringtone mode corresponds to a first melody and/or a first set of stamps, and the small ringtone mode corresponds to a second melody and/or a second set of stamps.

It is understood that different cams 90 can be superposed, in particular coaxial, or juxtaposed in a plane, and in particular chained to each other.

[0024] In addition to the mode selection, intended to ensure that only a mode chosen by the user is implemented by the ringing mechanism 100, the mode selector mechanism 9 ensures the deactivation of the ringing in silent mode, by moving away the pawls of the strike driving mobile 2, and makes it possible to prevent access to the hour piece at the corresponding cochlea.

[0025] In particular, the striking mechanism 100 comprises a minute repeater with a minute repeater control 4 comprising a repeater pawl 40, which is arranged to drive the trigger ratchet 22 after a reading performed by said hour piece 20 on the hour cochlea 190. And, in the silence mode, the main arm 64 of the silence rocker 60 allows access of the repeater pawl 40 to the trigger ratchet 22, as long as the energy available is sufficient for the running a full ringtone.

[0026] In a particular embodiment, the striking mechanism 100 comprises a large ringing mode for ringing at the passage of each hour, and of each quarter of an hour with the repetition of ringing from the hour to the quarter of an hour, and a small ringing mode for the ringing at the passage of each hour, and of each quarter of an hour without the repetition of ringing from the hour to the quarter of an hour. The striking mechanism 100 then comprises a small ring rocker 80, which is arranged to cooperate in bearing on a cam pin 97 that comprises the cam 90 of the mode selector mechanism 9) for, when the small ring mode is selected, orient the small ringing rocker 80 in a position in which it prohibits the passage of the hour piece 20 towards the hour cochlea 190, to prevent the ringing of the hours at the quarter-hours.

[0027] When, in this same arrangement, the grand strike mode is selected, the cam pin 97 orients the small strike rocker 80 into another position in which the latter authorizes the passage of the hour piece 20 towards the hour cochlea 190, to allow ringing when changing from hours to quarter-hours.

[0028] To differentiate the ringing when the hours and quarters of an hour pass, the ringing mechanism 100 advantageously comprises, coaxial with a star 130 of four driven by the output 3 and which is arranged to trigger the ringtones on the way to the quarters of the hour, a teardrop-shaped hour cam 131, comprising a tip 132 which is arranged to raise the small strike rocker 80, and authorize the passage of the hour piece 20 towards the hour cochlea 190.

[0029] The operation of the mode selector mechanism 9 does not hinder the operation of the minute repeater, and in particular in silent mode, except when, advantageously, the striking mechanism 100 includes a particular stop function arranged to prevent the execution of any ringing if the quantity of energy available 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 , in order to prevent the risk presented by the stopping of certain mobiles in intermediate positions, liable to cause collisions during a restart. In the only case where the stop function is effective, the operation of the minute repeater is also prohibited.

This stop mechanism 5 is arranged to rotate a ringing inversion rocker 59 when the available energy is insufficient for the execution of a complete ringing. This ringing inversion rocker 59 controls the pivoting of a ringing disengagement lever 55, which is arranged to prevent the access of the repetition pawl 40 to the trigger ratchet 22 when the energy available is insufficient for the execution a complete ringing, and to move the main pawl 85 away from the trigger ratchet 22 when the energy available is insufficient for the execution of a complete ringing.

[0031] The mode selector mechanism 9 is preferably designed to overcome the notching on the watch case, usual in the prior art: for this purpose, a selector lever 96 advantageously controls, in particular by an articulated connection such as visible in the figures, the pivoting of the cam 90, or cams 90 when there are several. More particularly, a cam jumper 91, associated with a cam jumper spring 92 for holding it in position, comprises a selector finger 99, which cooperates with one of the notches of the cam 90. This jumper 91 and its spring 92 have a dual function: to ensure the feeling of passing through the notches for the user, and the certainty of completing the selection manoeuvre, with a return to a clear position corresponding to one of the modes, and never to an intermediate position. Advantageously, the spring 92 is oversized to provide security, and in particular to overcome the friction forces of the seal in the watch case.

This cam 90 further includes a cam pin 97, which is arranged to constitute a stop for a small bell rocker 20, the function of which is explained below. Apart from the mode selection notches, the cam 90 advantageously comprises a continuous external profile 98 and comprising at least two feeler bearing zones, arranged to cooperate with a beak 61 which comprises a silence rocker 60: a greater radius 98S corresponding to a silent mode, and a zone of smaller radius 98AGS corresponding to a stoppage in grand ring mode, when the stop function and the grand ring mode exist.

The mode selection mechanism 9 can be used for different ringing mechanisms. Its interactions with the conventional components of a striking mechanism 100 comprising a minute repeater mechanism are illustrated in a particular arrangement which is detailed below, the person skilled in the art, specialist in striking for watches or mechanical timepieces , will be able to transpose them to mechanisms presenting variants.

This striking mechanism 100 is first exposed without a stopper mechanism.

[0035] Figures 1 and 2 show the mode selector 9 in the indexing position corresponding to notch 93 of the small ringtone, which strikes the full hours in passing, and the quarter hours only in passing. The quarter part and the usual quarter cochlea are not shown, so as to simplify the description of the operation.

The star 130, arranged near the mobile references 1, is arranged to come to cooperate, every quarter of an hour, with a beak 72, in particular elastic, that includes the lifting 70 of ringing trigger.

This hour part 20 includes a feeler 29 arranged to feel a cochlea hour 190, and a rake 25 arranged to cooperate with a rack pinion 24 that includes a striking driving mobile 2. This hour part 20 also includes , set back relative to feeler 29, a rib 23 which ends, on the same side as feeler 29, with a plate 27 for abutment support.

[0038] The mobile striking trainer 2 comprises meanwhile, in a conventional manner, a trigger ratchet 22, with which is arranged to cooperate, either a main striking pawl 85, or else a minute repeater trigger pawl 40 , provided with a pin 41, and which includes a minute repeater control 4, where this last pawl 40 cooperates with a spring 43.

The pivoting of the ring trigger lift 70 causes the pivoting of a trigger rocker 50 by the movement, which carries a thrust spring 52 which bears on the main ring pawl 85, which also carries the rocker trigger 50.

A small ring rocker 80 of the conventional type carries a stop pin 82. This small ring rocker 80, recalled by a release spring 83 fixed to a plate, comprises a release beak 81, which is arranged to take pressing on the cam pin 97, which the cam 90 comprises.

The small ring rocker 80 faces the hour part 20 during the angular stroke of the latter, and the stop pin 82 is at the level of the rib 23 of the hour part 20, on the same radius, which allows it to cooperate in abutment with the plate 27 of the hour part 20, and to immobilize the latter by preventing it from reaching the hour cochlea 190, so as not to repeat the striking of the hours every quarter, according to the operation specific to the small bell mode.

[0042] In order to ensure the striking of the hour at the full hour, the star 130 is integral with a teardrop-shaped hour cam 131, the tip 132 of which is arranged to raise the rocker from small chime 80, and therefore its stop pin 82, to allow feeler 29 of the hour 20 piece to pass through to read it on the hour snail 190.

[0043] Figures 3 and 4 show the mode selector 9 in the indexing position corresponding to notch 94 of the large ringtone, which strikes the full hours in passing, and both the hour and the quarter hour in passing. The usual quarter piece and quarter cochlea are not represented. The support of the cam pin 97 on the small bell rocker 80 is made at a greater distance from the end of the clutch release 81 than in the case of the small bell, and therefore the stop pin 82 n is no longer at the 23 rib, nor the 27 flat of the 20 hour piece, but is at the 28 undercut, allowing the 20 hour piece to swing freely to the 190 hour cochlea every quarter of hour.

For operation in silent mode, the ringing mechanism 100 comprises a large ringing and small ringing isolator, hereinafter referred to as silence rocker 60, which comprises at a first end a reading beak 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 bell pawl 85. This silence rocker 60 comprises, in its middle part near its pivot, a silence pin 63.

The spring 65 forces the silence rocker 60 via the pin 63, for this rocker is always in contact with the cam 90 by its beak 61. When the selected mode is the silence mode, this silence rocker 60 pivots and its part 62 disconnects the pawl 85 from the ratchet 22. The cam pin 97 is in contact with the clutch release 81 of the small ring rocker 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 hour rake 20 can fall on the hour cochlea 190 of part 1.

This silence rocker 60 is visible in Figures 5 to 11, which also include a stop mechanism 5, which essentially includes a ringing release lever 55. The ringing mechanism 100 thus comprises, partially superimposed, the silence rocker 60 and the ringing release lever 55, which are each arranged to hinder the access of a particular pawl to the ratchet 22 of the striking driving mobile 2. Indeed, the ringing release lever 55 comprises an arm stopper 56, which is arranged to stop a repeater pawl pin 41, which includes a minute repeater trigger pawl 40, of the minute repeater control 4.

The figures show the particular arrangement of the main pawl 85 and the minute repeater trigger pawl 40, which are both located on the same side of the striking drive mobile 2 and its ratchet 22, between the cam mode selection 90 and this ratchet 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 locking mechanism that is compact, reliable and efficient. This arrangement is made possible in particular by the interposition of the trigger rocker 50 between the lift 70 or first bell trigger rocker, and the main pawl 85: this trigger rocker 50 supports the articulation of this main pawl 85, and includes the spring 52 which pushes on this pawl; it allows the positioning of the main pawl 85 on the same side as the minute repeater trigger pawl 40 with respect to the ratchet 22, it reverses the direction of pivoting of the main pawl 85 with respect to a standard assembly where the latter would be in direct contact with lifting 70, and above all makes it possible to generate energy savings by precisely managing the engagement and exit of the beak of the main pawl 85 with respect to the ratchet 22. In particular, the main pawl 85 and the minute repeater trigger pawl 40 are substantially aligned thanks to this new arrangement, and the silence rocker 60 and bell release lever 55 can be superimposed, in an almost collinear fashion, which greatly simplifies the control and stopping of the bells, by reducing the number of components and the operating strokes of these components.

[0048] Figures 5 and 6 show the mode selector 9 in the indexing position corresponding to notch 95 of the silent mode, in which the small ringtone and the large ringtone are disengaged, but where the operation of the minute repeater is authorized . The read beak 61 of the silence rocker 60 bears on the largest radius 98S of the peripheral bearing surface 98 of the cam 90, and, therefore, on the one hand the small bell rocker 80 is stopped by the cam pin 97 and by the spring 67, and, on the other hand, the main arm 64 of the silence rocker 60 is in its furthest position from the striking drive mobile 2, and stops the main pawl pin 86. On the other hand, the striking disengagement lever 55 is very close to the striking driving mobile 2, since nothing opposes this extreme position, and therefore the minute repeater trigger pawl 40 is not hindered and can access the trigger ratchet 22, and the minute repeater can therefore be launched at will by the user.

[0049] Figures 7 and 8 illustrate stopping in ringtone mode, and show the mode selector 9 in the indexing position corresponding to notch 94 of the ringtone. 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 beak 61 of the silence rocker 60 rests on the smallest radius 98AGS of the peripheral bearing surface 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 bell driver mobile 2, and cannot stop the main pawl pin 86. On the other hand, the bell release lever 55 is in its position farthest from the bell driver mobile 2, and thereby obstructs both the main pin 86 of the main pawl 85 and the repeater pawl pin 41, so the main pawl 85 and the minute repeater trigger pawl 40 are impeded and cannot access the detent ratchet 22 The minute repeater cannot be activated by the user. No bell can therefore be launched. Nothing stands in the way of maneuvering the mode selection lever 96 into another position.

Figures 9 to 11 illustrate stopping in silent mode, and show the mode selector 9 in the indexing position corresponding to notch 95 of silent mode. These figures show an operating bolt 59 for the articulated control of the bell release lever 55. The reading beak 61 of the silence rocker 60 is supported on the largest radius 98S of the peripheral bearing surface 98 of the cam 90 , and the main arm 64 of the silence rocker 60 is in its furthest position from the strike driving mobile 2, and stops the main pawl pin 86. The strike release lever 55 is also in its furthest position of the strike driving mobile 2, and hinders the repeater pawl pin 41. Therefore the main pawl 85 and the minute repeater trigger pawl 40 are hindered and cannot access the trigger ratchet 22.

[0051] It is understood that the stoppage is active only in the case where there is no longer enough energy, and that, otherwise, this stoppage mechanism is disengaged.

[0052] Figures 13 to 19 illustrate a first variant of ringing mechanism combining a ringtone selection and a mode selection according to the invention, making it possible to play a first melody in the small ringtone mode, and a second melody different from the first melody in the grand ringtone mode.

[0053] Figures 20 to 29 illustrate a second variant of ringing mechanism combining a ringing selection and a mode selection according to the invention, making it possible to play one or the other of the first melody or the second melody, in each ring mode.

[0054] It is understood that the only limitation is that of the size inside the watch or the musical timepiece: these first and second variants are presented here with two melodies each, but it is understood that the striking mechanism could play more melodies, or even differentiate the melodies on different sets of gongs or gongs, in combination with the teachings of patent EP2947523B1 of the same applicant, and applications EP15190808.4, EP15168700.1, EP15183110.4 , and EP16206572.6 by the same applicant, the details of which are not repeated here. Similarly, mode selection can be performed by coaxial cams and/or juxtaposed cams in a plane.

The first variant comprises a melody selection cam 101, which cooperates with a first melody lever 103 and a second melody lever 104, which themselves cooperate with a melody selector 106, arranged to control the different lifts 107. Each of these levers 103 and 104 comprises an intermediate feeler nose, which runs on the periphery of the melody selection cam 101. The melody selection cam 101 comprises a pin 1010, which controls the fork 1050 of a melody selection probe 105, one of whose fingers 1051 cooperates with the periphery of a melody selection cam by mode 102. The latter is here in the same plane as the melody selection cam 101.

The second variant comprises, in a similar way, a first melody lever 103 and a second melody lever 104, which themselves cooperate with a melody selector 106, arranged to control the various lifts 107.

The mode and melody selection control is performed here by a mobile control 110, which comprises, stacked one on top of the other, several cams.

At the lower level, a first cam 111 is similar to the cam 90 presented above, and comprises notches 112 for jumper, and management of the small ringing, large ringing, silence modes, by its peripheral contour 113, which follows a beak 1090 that includes a passing ringtone isolator 109, arranged to prevent any interference between a minute repeater and a passing ringtone.

[0059] Each of the levers 103 and 104 comprises an intermediate feeler nose, which runs on the periphery, respectively of a first cam 114 for managing the first melody, and a second cam 115 for managing the second melody.

This control mobile 110 is extremely compact, is of lesser height than the bell mobile 2.

[0061] We see that these different variants use many common components, which reduces the cost of production, which is always high for grand complications.

The invention therefore provides the possibility of creating a wide variety of sets of differentiated ringtones, either controlled by the movement 200 of the watch or of the timepiece to ring as it passes, for example day/night, AM/ PM, weekly holiday, or other, either controlled by the user according to his tastes.

[0063] A watch 1000 includes a movement 200 including a ringing trigger output 3 on passage through the movement, this movement 200 being arranged to drive at least one reference mobile 1, and the watch 1000 includes at least one such mechanism of ringtone 100.

A timepiece 2000 comprises a movement 200 comprising an output 3 for triggering the ringing when passing through the movement, this movement 200 being arranged to drive at least one reference mobile 1, and the timepiece 2000 comprises at least one such striking mechanism 100.

Striking mechanism (100) for a timepiece (2000), in particular a watch (1000), comprising a movement (200), said striking mechanism (100) comprising at least one reference mobile (1) arranged to be driven by a said movement (200) and of which at least one said reference mobile (1) is an hour cochlea (190), and at least one striking driving mobile (2) comprising a detent ratchet (22) and a rack pinion (24), said striking mechanism (100) comprising at least one pivoting part arranged to cooperate indirectly with an output (3) of said movement (200), comprising a probe for reading a said mobile reference ( 1) and a drive rack for said rack pinion (24), one of said pivoting parts being an hour part (20) arranged to cooperate with said hour cochlea (190), said striking mechanism (100) further comprising a main pawl (85) arranged to be set in motion on each passing ring and drive said trigger ratchet (22), and said striking mechanism (100) being capable of operating according to at least two distinct ringing modes, one of which silence, characterized in that said ringing mechanism (100) comprises a mode selector mechanism (9), comprising a selector (96) accessible to the user to enable him to choose the ringing mode to be used, and which controls the angular position of at least one cam (90), which includes specific positions for different modes, said cam (90) including a continuous outer profile (98) for supporting the sensor, arranged to cooperate with a beak (61) that comprises a silence rocker (60), and which comprises a zone of greater radius (98S) corresponding to said silence mode, arranged to orient said silence rocker (60) in a position where a main arm (64) of said silence rocker silence (60) moves said main pawl (85) away from said detent ratchet (22), to ensure the deactivation of any ringing on passage, in silence mode. 2. Striking mechanism (100) according to claim 1, characterized in that said mode selector mechanism (9) comprises at least one said cam (90), which can include as many particular positions as there are modes attributable to the striking mechanism , or which includes positions specific to only some of these modes. 3. Striking mechanism (100) according to claim 1 or 2, characterized in that said mode selector mechanism (9) comprises at least one said flat cam (90), which comprises notches (93; 94; 95) corresponding each has one of the selectable modes (93; 94; 95). 4. Striking mechanism (100) according to claim 3, characterized in that said notches correspond to notches of variable amplitude, requiring an increasing force in one of the two operating directions. 5. Striking mechanism (100) according to claim 4, characterized in that a particular notch, in the center or in the vicinity of the center, is greater than those at the end, so as to ensure safety by avoiding the user from switching from one ring pattern to another unexpectedly. 6. Ringing mechanism (100) according to one of claims 1 to 5, characterized in that said mode selector mechanism (9) comprises at least one said cam (90), arranged to differentiate the playing of different melodies, and /or the set of different stamps. 7. Ringing mechanism (100) according to one of claims 1 to 6, characterized in that said mode selector mechanism (9) comprises at least one said cam (90) comprising multiple notches to differentiate between melodies and/or stamps assigned to each ring mode. 8. Striking mechanism (100) according to one of claims 1 to 7, characterized in that said mode selector mechanism (9) comprises a plurality of cams (90) superimposed, or juxtaposed in a plane. 9. Ringing mechanism (100) according to one of claims 1 to 8, characterized in that said mode selector mechanism (9) is arranged to ensure the deactivation of the ringing in silent mode, by moving said main pawl (85 ) of said strike driving mobile (2), and preventing access to said hour part (20) to said hour cochlea (190). 10. Striking mechanism (100) according to one of claims 1 to 9, characterized in that said striking mechanism (100) comprises a minute repeater with a minute repeater control (4) comprising a repeater pawl (40 ) arranged to drive said trigger ratchet (22) after a reading performed by said hour piece (20) on said hour cochlea (190), in that, in said silence mode, said main arm (64) of said rocker of silence (60) allows access of said repeat pawl (40) to said trigger ratchet (22), as long as the energy available is sufficient for the execution of a complete ringing.
