Detailed Description of the Preferred Embodiments

The invention relates to the field of watchmaking, and more specifically the field of timepieces comprising striking mechanisms, including repeating.

The invention relates to new complications brought to the striking mechanism.

In particular, the invention relates to the adaptation of a timepiece 1000 comprising a striking mechanism or large ringing or minute repeater 100, to use all or part of this mechanism called main bell, in as a sound display of another function, called secondary ring, different from the main ring, including a waking mechanism. The piece 1000 shown in the figures is a wristwatch, which incorporates various complications of the present invention.

By the general term "ringtone" is understood hereinafter any sound or musical emission, and in particular a sound emission produced by the percussion of a hammer on a stamp, or the like, according to the known mechanisms of timepieces. ring or music boxes.

FIG. 1 illustrates the constitution of a timepiece 1000 complicated, including a watch. This piece 1000 conventionally comprises at least one watch movement 200, and, on the one hand, at least one secondary ringing control mechanism 400 for triggering a so-called secondary ringing, for example an alarm bell, at a particular time linked to a preset , or / and upon receiving a signal, and / or when crossing a value threshold for a physical parameter, and on the other hand at least one striking or grand striking or minute repeating mechanism 100 controlled by main ring control means 10. These are interfaced with the watch movement 200, and arranged to trigger a main ring at times programmed by the watch movement 200, or on demand, in particular in the case of a repetition minutes, as the example illustrated by the figures. This mechanism 100 is preferably a repeating ring mechanism.

As the case may be, the watch movement 200 or the striking mechanism 100 comprises motor means 120 for driving a sound mechanism.

The timepiece 1000 comprises, in a preferred embodiment of the invention, illustrated by the figures, a secondary striking mechanism 1, which may consist of a wake up mechanism 300, and which advantageously comprises means mode selection 500 and clutch means 600. Nevertheless, the grouping of the functional blocks in FIG. 1 is indicative: one or the other may be part of another mechanism of the timepiece 1000, for example the selection means 500 may be integrated with the main ring control means 10, or the main striking mechanism 100.

This secondary ringing trigger mechanism 1 allows to use all or part of a main ring mechanism 100 to play a ringtone controlled by a secondary ringing mechanism, via clutch means 600 , and a control linkage 700 in the exemplary embodiment, which is advantageously coupled with isolation means 800 participating in the operational safety of the assembly, allowing only one command at a time to the sound emission mechanisms themselves. These include in all cases a ringer block 2 integrated in the main striking mechanism 100 or interface with him. In an advantageous variant, a secondary ring drive mechanism 350 incorporates a clutch mobile 150, interface with this ring block 2. In another variant for limiting the duration of a ring, a time limiter mechanism 330 incorporates a delay block 130 also interface with the ring block 2. Another optional security mechanism is an anti-snoc mechanism 900 which prevents any untimely maneuvering of launching a minute repeater, and which can be arranged between the mechanism of triggering secondary ring 1 and the main ring control means 10, or be integrated therewith, or the main striking mechanism 100.

The sound control mechanism 400 can thus be triggered by reaching a preset value, a time value in the case of an alarm clock, or the value of a physical quantity measured by a sensor such as the pressure in the case of a firing mechanism of a mine or torpedo, or as a threshold of radioactivity, temperature, or other, for personnel having to circulate in hazardous areas, and it can being triggered by the reception, at a receiver installed in the timepiece, of an external signal requiring a warning from the user of the timepiece, such as a telephone call signal or the like, these applications being cited as examples and not limiting.

Figs. 2 and 3 illustrate the cooperation, on a complicated timepiece 1000, of a repetitive striking mechanism 100, with its own complications, and of a secondary striking mechanism, in particular constituted by a mechanism of alarm clock 300. The particular functions will be detailed later in the description.

The striking mechanism 100 presented here is instantaneous trigger type, and resumes, as shown in Figs. 2 and 3, the features of the European patent application EP 1 798 611 of the same applicant, the content of which is incorporated by reference. In particular, the ringer mechanism 100 comprises a ringer block 2, which will be explained in detail in the following description, and which is adapted for the new features of the invention.

The watch movement 200 comprises a timer wheel, not shown in the figures, which drives a trigger cam 530 visible in FIG. 2 in the shape of a star of four. When the ringing is triggered, the ringing unit 2 drives a plate 525 carrying an arming cam 440, both visible in FIG. 3.

In automatic operation, the trip cam 530 causes the pivoting of a tripping lever 105, to a trigger ratchet 9, which comprises the ringing unit 2, which will be detailed later. Trigger lever 105 includes a first pawl 109, which drives the trigger ratchet 9 in pivoting, to release the gear of the ringer block 2.

In manual operation, a manual control member, such as the repeater minutes, linked to the first flip-flop 535, described above, according to the teachings of patent application EP 1798 611 of the same applicant incorporated here by reference, mechanically actuates the tripping lever 105. The arming cam 440 cooperates with an arm 441 that includes the tripping lever 105, visible in FIGS. 3 and 17, to control the arming thereof against a return spring. This arming cam 440 comprises a step, which allows to let down the tripping lever 105 during the tripping. The plate 525 comprises a pivoting hook 528, which, in the hooked position, at one of its ends, binds the plate 525 with a ratchet of a return wheel pivotally driven by the ring gear. An opposite end of this hook 528, visible in FIG. 2, cooperates with a locking device comprising a control arm with locking hook 529 and, in a preferred variant and illustrated here, a recess lever 531. According to its position, the locking hook 529 blocks or releases the cam armament 440, it therefore allows the stop or the triggering of all the ringtones according to its position. This locking hook 529 cooperates with a manual control lever for manually triggering the ring.

The recess rocker 531 is pivotally mounted on the manual control lever, biased by a spring, and cooperates at one end with the trip cam 530, and by a finger, with a pin carried by the control arm with locking hook 529, and it makes it possible to cause pivoting of the locking hook 529 in the unlocked position when the recess rocker 531 is itself released by the triggering cam 530.

The invention relates to a secondary ringing trigger mechanism 1 for such a timepiece 1000.

According to the invention, this secondary ringing trigger mechanism 1 comprises a clutch mechanism 600 arranged for, at this particular moment of triggering the secondary ringing mechanism 400, prohibit the execution of a main ring. by disengaging the main ringing control means 10, and for triggering a secondary ringing sound signal by clutching the ringing or ringing or minute repeating mechanism 100, or at least part of this mechanism. The mechanism 1 is further arranged for, outside of said particular instant triggering the secondary ringing control mechanism 400 and after the execution of the sound signal related to that particular moment triggering the secondary ringing mechanism 400, to allow the operation of a main ring by clutch of the main ring control means 10, and trigger a main ringing sound signal by clutch of the striking mechanism or large ring or minute repeater 100.

The trigger mechanism of secondary ring 1 according to the invention is particularly applicable to a timepiece 1000 which comprises several secondary ringing control mechanisms 400 hierarchized between them and priority on each other in cascade and all priorities on the main bell control means 10.

According to the invention, the secondary ringing triggering mechanism 1 then comprises means for comparing the priority levels of the secondary ringing control mechanisms 400, and an isolation mechanism 800 arranged for, at said particular time of triggering of one of said secondary ring control mechanisms 400, prohibit its operation if a sound signal of another secondary ringing mechanism 400 priority higher than hers is running, and allow its operation if no one sound signal from another secondary ringing control mechanism 400 of higher priority than its own is running, in which case said isolation mechanism 800 prohibits the operation of any other secondary ringing control mechanism 400 of priority lower than his.

The application of the invention is more specifically described for a particular case, illustrated by the figures, not limiting, wherein at least one secondary ringing control mechanism 400 is a wake up control mechanism 400 which comprises means set time setting of a desired wakeup time, not detailed here. In this case the secondary ringing triggering mechanism 1 is a wake up mechanism 300 controlled by a wake up control mechanism 400.

The secondary striking mechanism 1 or the timepiece 1000 comprises, preferably and in particular in the version illustrated by the figures, mode selection means 500.

These mode selection means 500 are arranged to differentiate, and select, at the timepiece 1000, at least on the one hand a secondary ring mode, including wake up, then activating the mechanism of secondary ringing command 400, in particular consisting of a wake-up control mechanism, and secondly one or more main ring modes, associated or not with a silent mode, by activating the main ringing control mechanism 10 which acts on a ringing pad 2.

For example, the mode selection means 500 may allow, on a timepiece 1000 provided with appropriate complications, to select different modes: alarm clock, large ring, ring, small ring, minute repeater, silence, this enumeration not being limiting.

These mode selection means 500 are arranged for, when the secondary ring mode, including alarm clock, is selected, arm the clutch mechanism 600 for the disengagement of the main ring and the clutch of a secondary ringing mechanism, in particular a wake-up mechanism 300, controlled by the alarm control mechanism 400, for controlling the execution of the alarm bell by a ringing block 2 that includes the big-bell mechanism 100. This mechanism of alarm clutch 600 is still arranged for, in case of selection of the main ring mode, disengage the secondary ringing mechanism or the alarm clock by the big ring, and for, or not to perform the secondary ring or alarm clock, or perform this secondary ring or waking by a mechanism other than the big ring.

The accumulation of energy, for the operation of the watch movement 200, and control mechanisms, alarm, and ringing, is not detailed here, nor in terms of reloading, nor in terms of storage. The energy storage means may be unique, for example in the form of a highly dimensioned barrel ensuring both a suitable power reserve watch movement 200 and a power reserve for the running of a number of ringtones and alarm tones, as known from EP 1 845 425 of the same applicant, the contents of which are hereby incorporated by reference. The energy storage means can also be differentiated, by the use of barrels, or the like, assigned to each of the functions.

The interface between the user and the timepiece 1000, for the selection and control of the ringing and waking functions, is, in the nonlimiting example illustrated by the figures and which relates to a part d 'minute repeater clockwork and big ring, consisting of three commands.

These three commands are added to the order specific to setting the time of waking, which is not detailed here, and which can advantageously include the characteristics of the European patent application EP 1 921 519 of the same applicant, whose contents are incorporated herein by reference. In a preferred embodiment, not detailed here, the timepiece 1000 comprises a pusher for performing the setting of the time of the movement, or setting the time of awakening, the action on this pushing start a clutch selecting one or the other timer.

The operation in secondary ring mode, including wake up, uses a secondary ringing control mechanism, including wake up, 400 arranged to trigger a sound signal, at a scheduled time, by the action of a mechanism. clutch 600 that includes the alarm mechanism 300.

Advantageously, because of its simplicity, the clutch mechanism 600 comprises a control linkage 700, comprising a large control 401, arranged to control a clutch mobile 150 for the execution of the secondary ringing or waking from a ringer block 2 that includes the large ring mechanism 100, and to control a delay mobile 130 to set the secondary ringing or waking time.

According to the invention, the alarm control mechanism 400 comprises a clutch mechanism 600 arranged for, in case of selection of the secondary ring mode or alarm clock, perform the secondary ring or wake up by the big ring of timepiece 1000. This clutch mechanism 600 allows, conversely, in case of selection of the main ring mode, to disengage this mechanism of ringing secondary ringing or the alarm clock by the big ring, and, or not to perform the secondary or wake-up ring, or to perform the secondary or wake-up ring using a mechanism other than grand arena, which is assigned to the display of the secondary or wake-up alarm, if the room watchmaking has such a mechanism, for example a vibrator. In the preferred embodiment, illustrated by the figures, this clutch mechanism 600, controlled by the large control 401, comprises a clutch mobile 150, which is shown in FIGS. 14 to 16.

Figs. 2, 3, 4and 19present, partially, a repetitive ringing mechanism 100 according to the invention, the conventional constituents of a large ringing or repeating ringing, in particular at minute repetition, are not all represented, the skilled person can refer to the book "Complicated watches" cited above to find the usual combinations.

The information taking organs of the ring are classically snails 101 hours, quarters 102 minutes 103 with surprise 103A, visible in FIG. 4. A trip lever 105, illustrated in detail in FIG. 17, is controlled by a control mechanism, such as a trip cam or similar, this flip-flop 105 is biased by a spring 107, and it comprises a second first pawl 109. This second first pawl 109 is intended to cooperate with the relaxation ratchet 9, that includes the ringing block 2, and which will be presented later.

The recurring ringing mechanism 100 includes parts of the minutes 110 and quarters 111, and for the ringing hours, a first lift 58 for driving a first hammer 108 on a stamp 117; in a particular variant, a second lift causes a second hammer 106. For ringing the minutes another lift 112 drives a small hammer 113. A rack rake 115 is used for arming the ring, it is intended to cooperate with a rack pinion 14 that includes the ringing block 2. A minute hook 116 can be fixed on the quarter part 111, to limit the ringing according to the number of minutes and quarters to ring, to prevent the mechanism from turning empty between quarters and minutes, the minute piece 110 then always stops at the same rest position.

A striking mechanism 100 comprises motor means, which may or may not be differentiated from those of the watch movement 200 itself. These motor means are not detailed here, they can take the form of a cylinder, a spring, or the like, generally powered by a user action on a rack push or the like. These motor means provide the energy necessary to perform the ringtone or ringtones. They are represented here only by a motor shaft 120, transmitting energy to the mobile generation of sound ringtones. This drive shaft 120 makes it possible to set in motion a ringer block 2, which directly communicates energy to one or more pivoting hammer lifts, which the ringer mechanism 100 comprises, to control, at the appropriate moment, the percussion one or more hammers on stamps, gongs, bells, or the like.

As will be detailed below, in a preferred embodiment illustrated by the figures, the secondary ringing triggering mechanism 1 comprises a special trigger rocker 105, specific to the invention, whose pivoting stroke is triggered, in automatic mode of ringing to a trigger ratchet 9 of the ringing unit 2 by a triggering cam 530 driven by a clockwork of the watch movement 200, or ringing on demand to the ratchet 9 by a minute repeater linkage actuated by a pusher 535 maneuvered by the user. This trigger rocker 105 cooperates with this trigger ratchet 9 then by means of a first pawl 109 that includes the trigger rocker 105. This first pawl 109 is biased by a first spring 109 A and serves to cooperate with the relaxation ratchet 9 for the big ring and the other main ringtones selected by the mode selection means 500.

According to the invention, as visible in FIG. 17, the trigger rocker 105 further comprises a second pawl 209 biased by a second spring 209 A and located in a plane parallel to that of the first pawl 109 and distinct from the plane thereof, and whose function is to cooperate with a toothing of a triggering wheel 118 of secondary ringing, including alarm clock, added to the ringer block 2 for actuating the alarm clock. The selection between the first pawl 109 and the second pawl 209 is performed by a selector lever 233 stage and articulated with the control linkage 700, itself controlled in displacement by the mode selection means 500.

Indeed, as visible in FIG. 17, the trigger rocker 105 comprises, at one of its ends, two pawls 109 and 209, in two parallel and neighboring planes, each spring-biased, respectively 109 A, 209 A. The first pawl 109 has the function of co-operating with the trigger ratchet 9 for the big ring and the other main ringing tones selected by the column wheel 500, while the second pawl 209 has the function of cooperating with the toothing of the trigger wheel 118 for the actuation of the secondary ring or alarm clock. The selector lever 233 is stage, and therefore has the function of choosing the appropriate ratchet according to the selected ring mode, and in particular the selector lever 233 allows, when necessary, to release the spout of the second pawl 209 of the toothing of the triggering wheel 118 of the striking block 2.

Thus, during its pivoting, the flip-flop 105 triggers, with one of its pawls 109 or 209, selected by a selection mechanism comprising a selector lever 415 and a selector lever 233, respectively the trigger ratchet 9 or the trigger wheel 118, te! that visible in fig. 7 and 13.

To do this, the large control 401 comprises a small arm 411, which is projecting laterally, relative to the rod of the large control 401. This small arm 411 has the function of driving a pin 415 A mounted to a end of a selector lever 415, which is pivotally mounted in its middle relative to the plate of the mechanism, as shown in FIGS. 10 to 12. As shown in FIG. 13, the other end of the selector lever 415 comprises a pin 415 B, for its articulation with the selector lever 233, which is pivotally mounted relative to a plate or a bridge of the timepiece.

The waking trigger wheel 118 is independent of the trigger ratchet 9 of the ringing block 2, and juxtaposed with it, each of them being able to act by a pin that includes each of them, but never at the same time, on a hook 5 driving a ratchet gun 11, which conventionally comprises the ringer block 2. This ratchet gun 11 is itself secured to at least one ratchet 13 cooperating with at least one lift 58 hammer for performing a bell.

The mode selection means 500 or a column wheel that comprises the latter, or which constitutes them, control the pivoting on a bridge of a hook 507. A first end of the hook 507 cooperates with a ratchet 505 integral with mode selection means 500, and a second end of the hook 507 is arranged to drive the control linkage 700, at the large control 401 arranged to drive, directly or indirectly via the selector lever 415 pivoting , the selector lever 233 which selects between the first pawl 109 and the second pawl 209.

The three commands for controlling the main ring and the secondary ring, including the alarm clock, are: - A control finger 501 for selecting a mode on a ring selector 500 constituting the mode selection means 500, which here comprises a column wheel, visible in FIG. 6; a pushbutton for triggering the minute repetition, not directly represented here, returned to the rest position by a spring 534, and directly controlling a first minute repeater 535; a pusher 211 for manually stopping the secondary ringer, or the alarm clock, connected by a spring 212 to a lever 210 for manually stopping the secondary ringer or the alarm clock, exposed later, and visible in FIGS. 2 and 3. This pusher 211 makes it possible to stop the secondary or wake-up ring before the end of the secondary ring or wake-up cycle.

The user selects, at the control finger 501, the desired operating mode of the striking mechanism. If it selects the secondary or wake-up function, the pusher 211 is made operative, otherwise it is disengaged. The selection made at the level of the column wheel 500 is exclusive of a single mode, or a secondary ring or alarm clock, or one of the main ring modes for which the ringing mechanism 100 is designed, including the silent mode. In silent mode, the minute repeater can be played in principle at any time, but security prevents the start of the minute repeater when another main ring, or a secondary or wake-up ring, is playing, and Conversely. A particular security constituted by an anti-snoc 900 mechanism presented below, and comprising a second pivoting pivot 536 and a pivoting lock 537, arranged to render inoperative the launch of the minute repeater, when it has already been launched and is still playing.

In FIGS. 2 and 6 is visible a time setting isolator 521, in accordance with the teachings of the patent application EP 1933 212 of the same applicant incorporated herein by reference, which allows to lock the time setting mechanism when a ring is engaged.

In wake function, the clutch mechanism 600, by its control linkage 700, sets up certain components, which, when the secondary or alarm mode is not selected, are isolated to leave the priority to the original main ringing function. This control linkage 700 essentially comprises the large control 401, in the form of a rod shown in FIG. 18, and which cooperates directly or indirectly with components assigned to the operating control of the secondary ring or alarm, to trigger the play of the secondary ring or the alarm clock, to limit the duration of this ring. These latter components are constituted respectively in the preferred embodiment shown in the figures by a clutch mobile 150, and a delay hook 141 associated with a delay mobile 130.

This large control 401 still cooperates with safety devices belonging to isolation means 800, including a first insulator 142 for limiting the movements of feeler fingers or rakes, as will be explained later.

The large control 401, visible in Figs. 6 and 8, can control the big ring to use part of its mechanism to play the alarm clock, or, conversely, to completely disengage the alarm function of the ringing functions. It governs all parts of the alarm clock, a clutch function, and ensures the proper implementation of all kinematics. In its application to a watch, the large control 401 traverses, substantially diametrically, the workpiece 1000, which allows a direct action, with a minimum of referrals, between functions whose mechanisms are remote. The large control 401 can be rigidly constructed, and thus effectively cooperates with safety functions preventing dangerous manipulations for the mechanisms.

The action of the user on the control finger 501 mode selection triggers the pivoting of the column wheel 500.

As can be seen in FIGS. 3 and 6, in a particular and nonlimiting embodiment, the column wheel 500 comprises, coaxial, four ratchets with four teeth, two of which are visible in the figures, the latter in opposite directions 502 and 503, it also comprises a cam 504 clover with 4 leaves, and a ratchet 505, which cooperates with a hook 507 pivoting on a bridge not shown.

As visible in FIG. 6, the hook 507 comprises a trunnion 432, or a pin, which is movable in an oblong slot 433 of the large control 401, and a spout which cooperates with the cam 504. The pivoting of the column wheel 500 thus causes pivoting the hook 507, the trunnion 432 pushes, at the oblong 433, fa great command 401.

In this particular embodiment, the large control 401 moves between two positions, one corresponding to the arming of the secondary ring, including wake up, for his game by the great ring, and the other the disarming of this secondary ring or waking.

The ratchet 502 of the column wheel 500 cooperates with a ratchet latch 512, one end of which includes a rake 513, for displaying the ringer mode selected at a wheel 514 meshing with this rake 513, such that that visible in fig. 3.

The ratchet 503 cooperates with an arm that includes a time insulator for small ring 506.

When the minute repeater is engaged, the first minute repeater 535 pushes the second flip-flop 536 of the minute repeater, which translates a weighing arm 523, rotating in turn a curve arm 522, which is arranged to cooperate with a recess 539 of the large control 401, as visible in FIG. 2. The arm 522 then pushes the large control 401, to isolate the alarm clock, the large control 401 is then blocked at its spout 430 by the spout 518 of a flip-flop 517, during the execution of the repetition minutes. After completion thereof, the flip-flop 517 is disengaged, then the large control 401 returns itself in place under the action of a return spring. The second flip-flop 536 is an effective security against untimely manipulation of the user.

The ringing unit 2, as shown in FIGS. 20 and 27, is a special embodiment built on a conventional basis, the invention adapts however without problem to different compositions.

This ringing unit 2 comprises a driving plate 3 to gun 4 pivotally mounted about a pivot axis D, shown in FIG. 35.

This drive plate 3 carries a pawl 5. The pawl 5 comprises a hook 6 beak 6A biased towards the axis D by a spring 7, as shown in FIG. 28.

Figs. 28 and 29 show a subassembly of a particular equipped drive plate, specific to the invention, formed on the basis of this drive plate 3, carrying the pawl 5, the spring 7, and a pivoting latch 181 with its return spring 183 as shown below.

The ringing unit 2 comprises a trigger ratchet 9, which is arranged to cooperate with a main ringing control mechanism 10, in particular to be driven by the second first pawl 109 of the trigger rocker 105.

The barrel 4 comprises pivoting drive means arranged to cooperate with a motor shaft 120 of a repeating ring mechanism 100.

The mechanism according to the invention is usable for a minute repeater, or for a large ring, as shown in the figures. Usually for a large ring, the watch movement 200 causes snails 101, 102, and 103, which provide at any time an exact time reference.

In main ring mode, the triggering of the ring, whether performed automatically or manually, causes the action of the first pawl 109 of the tripping lever 105 on the trigger ratchet 9, causing its pivoting. As a result, the pin 8 carried by this ratchet 9 circulates in the slot 3A of the drive plate 3, and pushes the hook 6, and then releases the toothing 12 of the barrel ratchet 11 which, in the rest position of the spring 7, meshes with the spout 6A of the hook 6.

The output stage of the ringer block 2, including the hour ratchet 13, can then rotate freely about the axis D. Under the action of springs that cooperate with the parts of quarters 111 and 111 minutes the hour ratchet 13 is pivoted under the action of the rack pinion 14 which is permanently driven by the rack 115, until a rack arm is stopped on the rim of the hours 101.

The spring of the quarter part 111 for its part pulls the quarter piece pinion 19, until the stop of an arm of the quarter part 111 on the quarter snail 102. The position taken 110 minute room arm on the minutes snail 103 is conventional, through the movement of the quarters room 111. When the bell starts, the pin 8 is released, and the spring 7 reenters the spout 6A of the hook 6 with the toothing 12 of the ratchet 11, which actuates the different levies on the respective hammers.

This relaxation ratchet 9, visible in FIG. 36, carries a pin 8, which can act through a slot 3A that comprises the drive plate 3 shown in FIG. 35, on the pawl 5, for the operation of the hook 6 under the action of such a main ringing control mechanism 10 or a tripping lever 105 or a first pawl 109 of such a rocker 105 that includes such a repetitive ring mechanism 100.

This pawl 5 is thus movable, preferably substantially radially, against the spring 7, that is to say towards the periphery of the plate 3, under the action of this pin 8.

As visible in FIG. 37, the ringer block 2 comprises a ratchet 11, which is arranged to be pivotally mounted on the barrel 4 of the drive plate 3, about the axis D. This ratchet gun 11 is designed to cooperate with the level of a toothing 12 that it comprises, with the spout 6A of the hook 6 of the pawl 5, as visible in FIG. 37. According to its position, this spout 6A allows or prohibits the pivoting of the ratchet 11.

The barrel ratchet 11 is pivotably mounted about the axis D with at least a first ratchet of hours 13, which is arranged to cooperate with at least one hammer drive lift 58 that includes the mechanism of repetition ring 100, to trigger a main ring. In a particular variant, the first ratchet of the hours 13 is pivotally integral with a second ratchet of the hours 15, which is angularly offset relative thereto, for triggering an additional ring, offset in time with respect to the basic ringtone, and in particular in certain time slots.

According to the invention, as visible in FIGS. 20, 27 and 30, the ringing unit 2 further comprises a triggering wheel 118, in particular triggering alarm when the secondary ring is an alarm bell, independent, for triggering a secondary ring, different from the main alarm . The secondary ring may in particular be played, using the energy of the same motor means 120 as those which operate the main ring, on at least one other stamp than the latter, by the action of at least one other lift on at least one other hammer, as illustrated in this particular and preferred embodiment. This trigger wheel 118 is juxtaposed to the trigger ratchet 9, each of them being able to act on the hook 6 by a pin, but never at the same time, to allow the transmission of energy to a sound mechanism for execute, respectively, the secondary ring, or the main ring.

Indeed, the trigger wheel 118 and the trigger ratchet 9 are independent of each other and each controlled by different control means selected to trigger the execution, respectively of the secondary ring, or of the main ring. And the trigger wheel 118 and the trigger ratchet 9 are both arranged to cooperate, but never at the same time, on the hook 6.

According to a preferred variant, the trigger wheel 118 is arranged to cooperate with a delay wheel 132 that includes a delay time-limiting device 130, explained below, to regulate and limit the duration of the execution of the secondary ring or alarm clock. Preferably, the control linkage 700, and in particular the large control 401, is arranged to block the delay wheel 132 at the end of the secondary ringing or waking cycle.

This delay mobile 130 has the function of limiting the duration of the secondary ring or the alarm to a predetermined value, for example to a duration of 20 seconds on the part 1000 illustrated by the figures.

According to another characteristic of the invention, the drive plate 3 comprises a peripheral toothing 119 arranged to cooperate with a clutch mobile 150 carried by a control linkage 700 of a secondary striking mechanism 1 corresponding to the other sound program called secondary ring.

This peripheral toothing 119 allows to use the driving force of a large ring mechanism to cause a secondary ring, here in the example of the figures a wake-up call. The example of waking is not limiting, other applications may be considered, such as the drive of a controller, or other.

More particularly, the ringing unit 2 comprises a drive plate 3 which has a peripheral toothing 119 for its cooperation with a pinion 158 that includes a clutch mobile 150, with which it meshes permanently, this mobile d clutch 150 being moved angularly by a large control 401 that includes the control linkage 700, to make, depending on its position, cooperate or not this pinion 158 with a pinion 159 carrying a star 161 which is arranged to cooperate with at least a lift 162 of a hammer 106 to perform the alarm clock.

Preferably, the ring unit 2 further comprises, mounted pivotably mounted about the axis D with the hour ratchet 13, a rack pinion 14, visible in FIG. 27, arranged to cooperate with the rack rake 115.

Preferably, the barrel 16 of the barrel ratchet 11 comprises a cylindrical seat 17 arranged to receive, pivotally movable, a quarter part gear 19 that includes the ring unit 2, visible in FIG. 25. This pinion 19 is arranged to cooperate with a quarter part 111 of such a striking mechanism 100, and carries a pin 21. This barrel 16 comprises pivoting drive means 18, for example under the form of a drive square or the like, a finger 22 that includes the ringing unit 2. This finger 22, visible in FIG. 27, comprises a bearing face 23, which is arranged to cooperate with the pin 21, to drive the pinion 19 pivotally when such a quarter part 111 pivots in a single pivoting direction suitable for driving the finger 22.

The finger 22 is secured to the hour ratchet 13 by its drive square, and it allows the pinion 19 to stop in a position that is imposed only by the quarter part 111. The angular difference between the bearing face 23 and the pin 8 is then all the larger as there are hours to ring, before the start of the ring.

The assembly of the ring 2 is formed by a screw or the like 24, bearing on a washer 24A and assembled with a motor shaft 120 or a mobile that carries it.

The barrel 4 of the drive plate 3 preferably comprises pivoting drive means, for example in the form of a driving square or the like, arranged to cooperate with the drive shaft 120 of the striking mechanism. at repeat 100.

The drive plate 3 comprises a light 3A for the passage of the pin 8 of the trigger ratchet 9 for the operation of the hook 6, under the action of such a main striking mechanism 10 or a tripping flip-flop 105 or a second first pawl 109 of such a flip-flop 105, that includes such a repetitive striking mechanism 100.

The trigger flip-flop 105 of the repeating large-bell mechanism 100, presses with its second first pawl 109 on the trigger ratchet 9, interposed between the drive plate 3 and the wake-up trigger wheel 118, and so on. drives this relaxation ratchet 9.

The trigger ratchet 9 is interposed between the drive plate 3 and the trigger wheel 118. As can be seen in FIGS. 30, 31, 34 and 36, this detent ratchet 9 comprises oblong slots 171 in which can move freely, with a limited angular stroke, screws 173 fixed on the face of the drive plate 3 opposite to that which supports the ratchet 5.

This trigger ratchet 9 further comprises another oblong slot 172, which allows a limited movement of a pin 175 mounted on the alarm trigger wheel 118, so as to limit the angular pivoting movement between them.

When the trigger wheel 118 pivots with respect to the deflection ratchet 9, the pin 175 that it carries then travels then an arc limited by a stroke limiting light 176 that includes the drive plate 3 as shown in FIGS. 29 and 32, and this pin 175 is arranged to push an end 186 of the pawl 5.

A locking latch 181 is pivoted on the drive plate 3, it comprises a cam 182, on which a spring 183 acts, which tends to rotate the latch 181 and to support a corner 184 thereof on a bias face 185, forming a ramp, of the pawl 5.

The action of the spring 7 then tends to bring the inner nose 6A of the pawl 5 on the barrel ratchet 11 of the downstream stage 1, and to lock it, except when precisely the pin 175 describes a bow of circle in its light 176, and presses on a front end 186 of the pawl 5 as visible in FIG. 29, which releases the tooth 6A of the ratchet 11.

When the pin 175 occupies the furthest position from the pivot of the cleat 181, the cleat 181 can tilt, under the action of the spring 183, and hold the pin 175, by a plate 187 that includes, te! that visible in fig. 33, and thus exert a locking action.

Once the ringing on the road, the stop 181 remains in lock support until unlocked at the end of the duration provided by the action of the delay wheel 132 on the trigger wheel 118, and the wheel Delay 132 will unlock it after running the secondary or wake-up ring for the expected time, preferably, this unlocking occurs before the delay wheel 132 has completed three quarters turn at the end of the ring.

When a secondary or wake-up alarm is triggered, at a programmed time, by a secondary or wake-up alarm control mechanism 400, the latter orders the trigger rocker 105 to rotate the wheel. trigger 118 of the bell block 2.

The manual control of the tripping lever 105 causes the movement of the flip-flops 523 and 522. The latter raises the large control 401. The flip-flop 517 then maintains, under the action of its spring, the large control 401 in this position, resting on its spout 430. The flip-flop 507 blocks the latch lever 517 as long as the minute repeater functions, if that is the case.

In operation in the main ring, the ringing unit 2, the pivoting of the trigger ratchet 9, is thus reflected by an angular stroke of its pin 8, which cooperates with the pawl 5 pivoting on the drive plate 3, and by the release of the spout 6A of the hook 6 with the toothing 12 that carries the ratchet ring 11 of the ringing unit 2.

In operation in the secondary ring, the pin 175 secured to the waking trigger wheel 118 drives the end 186 of the pawl 5, and thus raises the spout 6A of the hook 6, the locking by the cleat 181 authorizing a suspension in tripping of the trigger wheel 118.

The invention advantageously comprises an isolation mechanism 800, which is designed for any timepiece comprising on the one hand a watch movement 200, and on the other hand at least one striking mechanism comprising gripping sensors temporal information, on time references driven by this watch movement 200. According to the invention, this isolation mechanism 800, comprises at least a first insulator 142, arranged to cooperate with a control mechanism that includes this piece of timepiece 1000, for, in a first arming position to take a stop position prohibiting these temporal information capturing probes to seek information on these time references, and, in a second disarmament position, allow the passage of these probes to come into contact with these temporal references.

More particularly, this isolation mechanism 800 is arranged for the isolation between triggering mechanisms of different sound signals using, at least partially, the same striking mechanism or large ring or minute repeater 100 for execution of these sound signals. In particular, in the case where at least one of them is a main ringing control mechanism arranged to trigger a main ring at times programmed by a watch movement 200, or on demand, and whose sequence of each Ringing is determined by the search for information, by time probing probes, on time references driven by the watch movement 200. And at least one of these other mechanisms is a secondary ringing mechanism 400. This timepiece 1000 further comprises a secondary ringing triggering mechanism 1 comprising a clutch mechanism 600 arranged to allow exclusive operation at a given time, or of a single secondary ringing mechanism 400, or the only main bell control mechanism 10.

According to the invention, the isolation mechanism 800 comprises at least this first isolator 142, arranged to cooperate with this clutch mechanism 600, and, when it is armed by such a secondary ringing mechanism 400, arranged to take a stop position prohibiting temporal information pickup probes, which comprise the main ring control means 10, to search the time reference information as long as the secondary ringing mechanism 400 is operating, and for on the contrary allow the passage of these probes to come into contact with the time references when the secondary ringing control mechanism 400, for example an alarm mechanism 400 in the example of the figures, is disarmed and the main ringing control mechanism 10 works.

The isolation mechanism 800 further comprises a stop constituted by a delay hook 141 carried by the same large control rod 401 as the first isolator 142, and which is pivotally mounted on the large control rod 401, and which participates in the limitation of stroke probes temporal information acquisition.

The control linkage 700 controls the isolation mechanism 800, which comprises at least a first isolator 142 controlled directly or indirectly by a large control 401 actuated by the mode selection means 500, to take a stop position prohibiting to temporal information pickup probes, which comprise the main ring control means 10, to seek information on time references driven by the watch movement 200 when the secondary ringing or alarm clocking mechanism 400 operates to control executing the secondary or alarm bell, and to allow the passage of these probes to come into contact when the secondary or alarm bell control mechanism 400 is disarmed and the striking mechanism or large ring 100 operates.

Thus, the trigger wheel 118 is released, but the rakes of the rack 115, the quarter part 111, and the minute piece 110, can not take their information on their respective snails, hours 101 , quarters 102, and minutes 103, because they are prevented by stops or latches constituted by a delay hook 141 and by an isolation mechanism 800, which comprises a first insulator 142 for locking the rakes. This delay hook 141 and this first insulator 142 are controlled by the large control 401, as visible in FIG. 8, and by a time blocker of the small ring 506 visible in FIGS. 2 and 3. The first isolator 142 preferably comprises a boss 407 designed to obstruct in different parallel planes temporal information captors, including rakes or fingers.

Therefore, the drive plate 3 begins to rotate, but, as the finger 6A of the hook 6 is blocked in the air, it can not cause the account of the big ring. But, as explained above, the peripheral toothing 119 of the drive plate 3 drives the pinion 158, mounted on an arm of a clutch mobile 150.

In the embodiment illustrated in FIG. 14, which is in no way restrictive, the clutch mobile 150 has three arms, so as to allow access to other components. One of these three arms 156 carries the pinion 158 which cooperates permanently with the toothing 119 of the drive plate 3.

A second arm 154 carries a pin 157, which is movable in a window 431, here of substantially square shape, that includes the large control 401, whose position therefore determines the angular position of the clutch mobile 150. The third arm 155 carries a pin 191 for attachment to a return spring 190.

In one of the clutch mobile clutch 150 positions, the pinion 158 meshes with another pinion 159 mounted pivotally integral with a star 161. This star 161 controls the movement of at least one lift 162 to perform the alarm of the alarm by activation of a hammer 106, at a speed determined by the number of branches of the star 161.

During the execution of this movement, a so-called delay time delay command 130 is activated. This delay mobile 130 for clock mechanism, is designed to limit the duration of execution of a function after its release, and is arranged to cooperate with a trigger element whose start of movement initiates the triggering of this function. It is still arranged to cooperate with clutch means 600 of this function. According to the invention, the delay mobile 130 comprises a delay hook 141 arranged to be maneuvered by these clutch means 600 for its cooperation with a ratchet 133 or for its release of the ratchet 133. This ratchet 133 is mounted pivoting on an axis coaxially with a delay wheel 132 to which it is pivotally recalled by elastic return means 135. This delay wheel 132 is arranged to cooperate, directly or indirectly, with this trigger element.

This delay mobile 130, shown in FIG. 24, adjusts the duration of a signal, especially here the duration of the alarm clock. It can be used for any other desired time delay in the timepiece, or for applications derived from the watch industry, such as explosive firing retardants, or others.

This ratchet 133 comprises abutment means 136 arranged to cooperate, in a disarming position of the delay wheel 130, resting on complementary abutment means 137 integral with the delay wheel 132. These abutment means 136 and these complementary abutment means 137 are spaced from each other under the effect of the movement of the trigger element driving the delay wheel 132 by arming the elastic return means 135 when the ratchet 133 is pivotally immobilized by the delay hook 141.

This delay mobile 130 includes a delay wheel 132 meshing with the trigger wheel 118. Coaxially to this delay wheel 132 are mounted a plate 131 whose one end is pressed on the wheel delay 132, and a ratchet 133. This delay ratchet 133 is mounted prisoner between the plate 131 and the delay wheel 132, but free to pivot relative thereto. The delay ratchet 133 comprises a pin constituting the abutment means 136, mounted parallel to the pivot axis, so as to be able to interfere with a radial pin constituting the complementary abutment means 137 that the plate 131 comprises.

The pin 136 of the delay ratchet 133 also serves as a hooking at one end of a spiral spring constituting the elastic return means 135, the other end is carried by a plug 134, a bore 139 cooperates with with another tree part 138 of the plate 131.

The delay ratchet 133 cooperates with the delay hook 141, which is preferably articulated with the large control 401, and which retains the delay ratchet 133, as visible in FIG. 11.

The invention also relates to a time limiter mechanism 330 comprising such a delay mobile 130, and which comprises this trigger element, consisting of a trigger wheel 118 of a triggering mobile or a ringing block 2.

This trigger wheel 118 comprises, as shown in FIG. 32, a pin 175 parallel to its axis. The triggering mobile, or the ringing block 2 as in the application illustrated in the figures, comprises locking means 181 on which are exerted, antagonistically, the forces exerted on the one hand by the pin 175 of the trigger wheel 118 which meshes with the delay wheel 132, and secondly by a spring 183, as visible in FIG. 29.

In a first pivoting stroke of the delay wheel 132 relative to the delay ratchet 133, the return force exerted by said elastic return means 135 via said pin 175 on said locking means 181 is less than the force exerted on said locking means 181 by said spring 183 to allow the unfolding of said function under the driving of a ratchet 11 connected to the motor means 120. While in a second pivoting stroke of the delay wheel 132 relative to the delay ratchet 133, the return force exerted by the elastic return means 135 via the pin 175 on the locking means 181 is greater than the force exerted on the locking means 181 by the spring 183, and allows a movement of the pin 175 to release the closing movement of a pawl 5 on the ratchet barrel 11 to stop the exé implementation of the function concerned.

In the particular application illustrated by the figures, the time limiter mechanism 330 constitutes a mobile ringing time limiter, and the trigger wheel 118 belongs to a ringing unit 2 comprising a driving plate 3 to barrel 4 mounted pivoting about a pivot axis D, this drive plate 3 carrying the pawl 5 having a hook 6 beak 6A biased towards the axis D by a spring 7. This pawl 5 is movable against the spring 7 under the action of a pin 8 that includes a trigger ratchet 9 that includes the ringing unit 2, and which is arranged to cooperate with a main ringing control mechanism 10. The ringing unit 2 comprising said ratchet to barrel 11 is arranged to be pivotally mounted on a barrel 4 about the axis D and to cooperate, at a toothing 12 that it comprises, with this spout 6A which, according to its position, allows or prohibits the pivoting of the ro 11. This barrel ratchet 11 is mounted pivotally mounted about the axis D with a first hour ratchet 13 arranged to cooperate with a first hammer drive of a striking mechanism. The trigger wheel 118 is independent of the trigger ratchet 9 and controlled by other control means than this main striking mechanism 10, and the trigger wheel 118 and the trigger ratchet 9 are both arranged to cooperate, but never at the same time, on the hook 6 to allow the transmission of energy to a sound mechanism to perform, respectively, different sound emissions.

In this time limiter mechanism 330, the locking means 181 are preferably constituted by a locking latch which is pivoted on the drive plate 3. This latch 181 carries a cam 182, on which the latch acts. spring 183, which tends to rotate the latch 181 and to support a corner 184 thereof on a biased face 185, forming a ramp, the pawl 5. And the action of the spring 7 tends to bring the inner beak 6A ratchet 5 on the barrel ratchet 11, and lock it, except when the pin 175 describes a circular arc in a slot 176 that includes the drive plate 3, and presses on a front end 186 of the pawl 5 to release the tooth 6A of the barrel ratchet 11. When the pin 175 occupies the furthest position from the pivot of the cleat 181, the cleat 181 switches under the action of the spring 183 to hold the pin 175, by a plate 187 which it comprises , and thus exerts a lock action illage.

When the alarm triggering wheel 118 of the ringing unit 2 drives the delay wheel 132, counter-clockwise in FIG. 22, and thus drives the plate 131, the spiral spring 135 is armed, since the delay hook 141 then blocks the ratchet 133; the radial pin 137 for minimum retention of the plate 131, which was in abutment with the pin 136 of the delay ratchet 133, leaves it, and describes an angular stroke. This angular travel is preferably limited to 270 °, at this point the force exerted by the balance spring 135 balances the locking force of the hook lock 5.

In the wake function, the delay hook 141 holds the ratchet 133, so as to exert a torque on the drive plate 3, so as to overcome the force of the spring 183, to be able to rest the cleat of latch 181 visible in FIG. 29. The spiral spring 135 is calibrated according to this spring 183. Thus, when the cocking of the spiral spring 135 is greater than the force of the spring 183, the pin 175 of the wake-up trigger wheel 118 pushes the cleat locking 181, which frees the hook 5, which hooks the barrel ratchet 11 of the delay mobile 2, and restarts the assembly after a few degrees of pivoting, the ringing is then stopped.

When the hook 141 is released, the ratchet 133 pivots to resume its standby position, where its pin 136 is resting on the pin 137 of the plate 131. The delay mobile 130 rotates freely if the hook 141 is lifted .

The delay hook 141 carries a pin 405, visible in FIG. 10, which is arranged to be able to lock the delay wheel 132, so as to force the trip lever; in manual operation it is thus possible to block the wheel to short-circuit the delay mobile 130.

The delay hook 141 is then returned to its freedom, and it returns to the ratchet, and releases the ringing unit 2; the delay hook 141 hangs up the alarm triggering wheel 118, and still causes a few degrees the large ring assembly, to come put the various rakes in the rest position.

Thus all the parts are at rest, the delay hook 141 releases the delay ratchet 133 resuming under the effect of the spiral 135. Meanwhile the pivot 405 of the delay hook 141 on the large control 401 comes interfere with the teeth of the delay wheel 132, and locks it.

[0140] Activation or deactivation of the secondary ringing or alarm function includes the operation of the large control 401. When disabling the secondary or alarm ringer function, this large control 401 acts on the clutch mobile 150, belonging to the clutch mechanism 600. The large control 401 therefore acts on the clutch mobile 150, away or closer, as the case may be, the pinion 158 of the pinion 159 carrying the star 161.

The first isolator 142, which is pivotally mounted at a pivot 408 on a not shown bridge, then leaves the path of the quarter part 111, and the delay hook 141 is held in the air.

The cycle of the different ringtones can then resume its course, and the selector lever 415 can select one of the two ratchets 109 or 209.

Thus, the invention uses all or part of the great ring mechanism to perform the sound display of the secondary ringing or alarm function.

The first insulator 142 is movable, at a trunnion 404 that it comprises, in a groove 403 that includes the large control 401 disposed obliquely with respect to the longitudinal direction thereof, as visible in FIG. fig. 11.

This first insulator 142 has a protruding boss 407407, arranged to create an obstacle on the path of the rakes of the parts of the quarters 111 and minutes 110, and, as shown in Figure 8, to prevent them from coming to contact of the respective snails of the quarters 102 and minutes 103. Thus, this first isolator 142 does not prevent the buzzer from functioning as a generator of a sound signal, but prevents it from operating under the control of the quarter parts 111 and The mechanism of the striking hammers can thus generate an alarm bell.

The movement imposed on the large control 401 makes it possible to advance or retract the delay hook 141. A groove 403 formed in the large control 401 makes it possible to pivot the first isolator 142. At one end of the large control 401, a window 431 allows the pivoting of the clutch mobile 150, shown in FIGS. 14 to 16, which comprises an arm 154 provided with a pin 157 movable in this window 431.

The control linkage 700 controls the isolation mechanism 800 which preferably comprises at least one second isolator 143 controlled directly, or indirectly by a large control 401 actuated by the mode selection means 500, to put into operation, or out of service, depending on its position, a delay hook 141 which cooperates with a delay ratchet 133 that includes a delay mobile 130 arranged to adjust the duration of a secondary ring signal, or alarm clock, controlled by the secondary ringing mechanism 400.

Thus, the mechanism further comprises a second isolator 143, visible in FIGS. 8 to 11, and 18, and which is integral with the large control 401. This second insulator carries a large arm 143A, projecting obliquely relative to the longitudinal direction of the large control 401, visible in FIG. 10, and whose function is to put into operation, or out of service, according to its position, the delay hook 141. The latter is recalled by a spring 406A visible in Figs. 10 and 14, and the large arm 143 A abuts at a pin 406.

The time limiting mechanism 330 advantageously comprises a lever 210, visible in FIG. 10, linked, via a spring 212, to a pusher 211, to manually stop the ringing, in particular the alarm bell in this preferred application, and which is arranged to rotate the delay hook 141, for the stall of the delay hook 141, so as to unlock the delay wheel 132 during an action of a user on the pusher 211. For the stall of the delay hook 141, the lever 210 is arranged to cooperate with a song rounded delay hook 141, under the arm 143A, which also serves as a guide surface for the lever 210 which is very long. The action on the pusher 211 then makes it possible to unlock the delay wheel 132, through the lever 210 and the delay hook 141, which the lever 210 then rotates.

In a non-limiting embodiment of the invention and which makes it possible to arrange it in a plane that is offset from that of the large control 401, the small arm 411 of the large control 401 is integrated in the second isolator 143. and protrudes laterally from the side opposite to that of the large arm 143A, relative to the large control 401.

[0151] Preferably, when the striking mechanism or large ringing or minute repeater 100 comprises a minute repeater mechanism operable by a user by pressing a push pushing a first flip-flop 535 control a minute repeater, the mechanism 1 comprises a security anti-snoc mechanism 900.

This anti-snoc 900 security mechanism is designed against untimely manipulations of minute repeater control, and is studied for a timepiece 1000 which includes a watch movement 200 itself having a timer wheel which causes a Trigger cam 530. This cam 530, in automatic operation, causes the pivoting of a trigger rocker 105 to a trigger ratchet 9 that includes a ring 2 of such a striking mechanism 100 having a minute repetition. This ringing unit 2 is arranged to, when performing a ringing, drive a plate 525 carrying an arming cam 440.

According to the invention, this anti-snoc mechanism 900 is arranged to cooperate with this first flip-flop 535, it comprises a second pivoting safety flip-flop 536, whose pivoting is controlled by the first flip-flop 535 when the minute repeater is engaged. . This second flip-flop 536 includes a notch 536A which is arranged to cooperate with a finger 537A that includes a pivoting latch 537 spring-biased, to prohibit the retrigger of the repetition minutes once it is launched. The lock 537 is released only at the end of the time display ring cycle by the minute repetition.

This anti-snoc mechanism 900 consists of two parts: - The user interface, consisting of the push button of the repetition minutes, recalled in the rest position by a spring 534, and directly controlling a first latch 535 minute repeater; - An intermediate pusher, connected to the triggering of the striking mechanism, which comprises, arranged to cooperate with the first flip-flop 535, a second latch 536 safety trigger bell.

The pivoting of the second flip-flop 536 is controlled by the first flip-flop 535 when the minute repetition is switched on. As shown in fig. 21, the second flip-flop 536 comprises, on the one hand a notch 536A, which is arranged to cooperate with the finger 537A of a spring-loaded pivoting latch 537, to prohibit the restart of the minute repeater once the one It is launched, and secondly a nozzle 536C, whose function is to disconnect a minute blocker not shown here. Manual pressing on the pusher rotates the second flip-flop 536, and tends to release the safeties to allow probes probes temporal information, consisting of fingers that include rakes and / or parts of quarters and minutes, to search the information relating to the ringing sequence to be played by the main ring, on time references, constituted by snails or the like, driven by the watch movement 200.

The lock 537 is released only at the end of the hour display ring cycle by the minutes repetition, the pivoting of the second flip-flop 536 translates a weighing arm 523, which in turn rotates a weighing arm 522 arranged to cooperate with a recess 539 of the large control 401. The weighing arm 522 then pushes the control linkage 700, in particular the large control 401, to isolate the alarm clock, by blocking it at a spout 430 of the large control 401 by a spout 518 of a latch 517, during the execution of the repetition minutes. This latch 517 is disengaged after the completion of the minutes repetition, to let the large control 401 return into place under the action of a return spring.

Thus, as shown in FIG. 5, the minute repeater flip-flop 535 is arranged to cause the pivoting of a second minute repeater flip-flop 536, a notch 536 A of which is arranged to cooperate with the finger 537A. a spring-loaded pivoting latch 537 to prohibit re-engagement of the minute repetition once it is started. It is only at the end of the hour display ring cycle by the minute repeater that this lock 537 is released, and again authorizes a command on the trigger for triggering the minute repeater.

The first latch 535 comprises a spring 535A, a sloping end 535C presses on a pivoting arm 535B which also comprises the first latch 535, or at the end of a substantially circular cam 535D of this arm 535B, in a rest position visible in FIG. 21A, or inside this cam 535D in the positions of FIGS. 21B, relating to the triggering of the ring, and 21C, relating to the locking of the second flip-flop 536 constituting an intermediate pusher.

The second flip-flop 536 comprises a spout 536B, which is arranged to cooperate in support with a pin 523A that comprises an arm 523. The second flip-flop 536 still carries, pivotally, a recess rocker 531, including a bearing face 531A is arranged to push a bearing face 529A of a hook 529 pivotally mounted on a plate or a bridge. The arm 523 comprises a second pin 523B arranged to exert a bearing, in the opposite direction, on an opposite bearing face 529B of the hook 529.

[0160] Figs. 21A, 21B, 21C illustrate three successive stages of operation of this anti-snoc mechanism 900.

[0161] In FIG. 21A, the system is at rest. The sloped end 535C of the spring 535A presses the end of the cam 535D of the pivot arm 535B. This pivoting arm 535B is supported, by a first bearing surface 535E, on the second flip-flop 536. The second flip-flop 536 is in a position such that the bolt 537 is disengaged from the notch 536A. The pin 523B of the arm 523 does not act on the hook 529.

FIG. 21B relates to the triggering of the ring. The pusher 535, under the action of the user, pivots in the direction of the arrow A, and the spring 535A presses on the inside of the cam 535D. Thus the arm 535B pushes the second flip-flop 536 by a second bearing surface 535F. The second flip-flop 536 then hooks the lock 537. Its pivoting causes the arm 523, which is driven, at its pin 523A, to be displaced by the nose 536B of the second flip-flop 536. And this arm 523 drives itself, by its second pin 523B, the bearing surface 529B of the hook 529. This movement allows to release the hook 529 of a pivoting hook 528 visible in FIG. 2, armed by a plate spring 532. This hook 528, in the hooked position, binds, at one of its ends, the plate 525 with a ratchet of a wheel driven pivotally by the ring gear. The pivoting of the lock 537 allows it to be supported on a rocker 540, and to rotate it. This latch 540 then releases a stamp isolation mechanism 542, related to the movement of the minute piece 110 and object of the European patent application 09175266.7, incorporated herein by reference. Pivoting the pivoting hook 528 allows pivoting of the tripping lever 105, in the direction of the arrow C under the action of its spring 105A, the hook 109 then cooperates with the ratchet 9 of the ringing unit. The ringtone on demand then starts to play.

[0163] FIG. 21C relates to the locking of the second flip-flop 536. When fully supported on the first flip-flop 535, the restoring torque exerted by the spring 534 tends to return the first flip-flop 535 to the rest position. The second flip-flop 536, which is no longer held by the first latch 535, tends to pivot in the direction of the arrow B, and comes, during this movement, hook, by a flange of the notch 536A, a redan 537B that includes the 537A finger of the lock 537. It is then impossible to restart the ring before it has finished playing.

At the end of the game of the ring on demand, the latch 540 rotates the lock 537, which then releases the second latch 536, which can return to the rest position of FIG. 21 A.
