This application claims priority from European patent application No. 17182975.7 filed on Jul. 25, 2017, the entire disclosure of which is hereby incorporated herein by reference.

FIELD OF THE INVENTION

The invention concerns a striking mechanism for a watch or timepiece comprising a movement, said striking mechanism comprising at least one reference wheel set arranged to be driven by a said movement and wherein at least one said reference wheel set is an hour snail, at least one strike drive wheel set including a detent ratchet and a repeating rack pinion, said striking mechanism including at least one pivoting part arranged to cooperate indirectly with an output of a said movement, including a feeler arm for reading a said reference wheel set and a rack for driving said repeating rack pinion, one of said pivoting parts being an hour-rack arranged to cooperate with said hour snail, said striking mechanism further including a main click arranged to be set in motion at each passing strike and to drive said detent ratchet, and said striking mechanism being able to operate in at least two distinct strike modes including a silent mode, wherein said striking mechanism includes a strike selector mode, comprising a user-accessible selector which allows the user to choose which strike mode to use and controls the angular position of at least one cam, which has particular positions for different modes, said cam having a continuous, external, feeler arm support profile, arranged to cooperate with a beak comprised in a silencing lever, and which has an area of larger radius corresponding to said silent mode, arranged to orient said silencing lever into a position where a main arm of said silencing lever moves said main click away from said detent ratchet, in order to disable every passing strike, in silent mode.

The invention also concerns a watch comprising a movement including an output for releasing the passing strike function by the movement, this movement being arranged to drive at least one reference wheel set, and the watch includes at least one such striking mechanism.

The invention also concerns a timepiece comprising a movement including an output for releasing the passing strike function by the movement, this movement being arranged to drive at least one reference wheel set, and the timepiece includes at least one such striking mechanism.

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

BACKGROUND OF THE INVENTION

Timepiece striking mechanisms are large complications, which are complex as regards not only the number and complexity of the kinematics of their components, but also their possible operating modes. Choosing between the various strike modes is in itself an additional complication, which employs expensive components, such as column wheels or the like, and which takes up significant space inside the watch or timepiece case, which often has a set of notches for this selection function. The interface between the selection mechanism and the exterior of the case must also enjoy a particular seal tightness. Managing safety features between the various modes is always complex.

For watches that have additional complications, such as minute repeaters, managing safety features is very complex, and it is difficult to stop the passing strike function to allow a minute repeater to play, or conversely, to stop a minute repeater being released as a passing strike approaches, to prevent a minute repeater being released again when a repeater cycle has just started, to prevent an adjustment to the motion work during a striking function, etc., as these safety means generally employ a large number of isolators, which further complicates the mechanism and the risk of interference.

Swiss Patent No CH706080B1 in the name of PATEK PHILIPPE discloses a timepiece including a case enclosing a mechanical timepiece movement, including a repeater mechanism that can be released automatically by the mechanical timepiece movement, wherein the repeater mechanism includes a release lever provided with a click which is pivotably mounted on said release lever and arranged to move into engagement with the toothing of a detent ratchet comprised in the fusee of the repeater mechanism, so that, on automatic release, a nut driven by the motion work of the movement, preferably integral with the cannon pinion of the movement, causes the release lever to pivot towards the detent ratchet, and so that, when the release lever drops, the click beak drives the detent ratchet in rotation; the repeater mechanism includes a strike mode selection mechanism. This strike mode selection mechanism includes an operating member that is accessible from outside the timepiece and formed of a slide-piece, mounted to slide in a back-and-forth movement on the periphery of the timepiece case between at least two positions, one corresponding to a strike mode and the other to the silent mode.

CH Patent Application No 704590A1 in the name of MONTRES BREGUET SA discloses an isolating mechanism for a timepiece, including, on the one hand, a timepiece movement and, on the other hand, at least one striking mechanism including feeler arms for reading time information, on time references driven by said timepiece movement. This isolating mechanism includes at least a first isolator, arranged to cooperate with a control mechanism comprised in the timepiece, in order, in a first armed position, to adopt a stop position that prevents the time information feeler arms from searching for information on the time references, and, in a second unarmed position, to allow the feeler arms to pass and come into contact with the time references.

Swiss Patent No CH711258A2 in the name of RICHEMONT discloses a selector device for a timepiece striking mechanism, the striking mechanism being drivable by a strike train and configured to be placed in a ‘strike’ mode, in which the striking mechanism is always activated, a ‘night-time’ mode wherein the striking mechanism is disabled only for a predetermined period of the day, or a ‘silent’ mode in which the striking mechanism is always disabled; the selector device including: a cam completing one rotation in 24 hours and having the profile required for said predetermined period, a first lever, configured to switch between a first position, in which the first lever does not cooperate with the cam, so that the striking mechanism is in ‘strike’ mode, and a second position in which the feeler arm cooperates with the cam so that the striking mechanism is in ‘night-time’ mode; and a second lever, configured to switch between a first position, in which the striking mechanism is connected to the strike train, and a second position, in which the striking mechanism is disconnected from the strike train so that the striking mechanism is in ‘silent’ mode. This selector device comprises a push lever that can be actuated to tilt the first lever and the second lever to place the striking mechanism in one of the ‘strike’, ‘night-time’ or ‘silent’ modes.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The invention concerns a watch1000or a timepiece2000including at least one specific striking mechanism100. This timepiece2000may be a music box or include a music box.

The work by François LECOULTRE entitledLes montres compliquées(A Guide to Complicated Watches), Editions Horlogères, Bienne (Switzerland), 1985, ISBN 2-88175-000-1, explains, in detail, the basic mechanisms forming striking mechanisms, at pages 97 to 205 (pages 85 to 181 of the English edition), in different chapters:repeating watches,old repeating watches,modern quarter-repeater,simplified repeater,half-quarter repeater,Breguet half-quarter repeater,five minute-repeater,minute-repeatersclock watches
Unless necessary, these basic mechanisms will not be discussed here in detail, since striking mechanism specialists will know how to find the composition of such mechanisms in this universal reference work, in particular in the aforementioned last two chapters.

Striking mechanism100according to the invention includes, in a conventional manner, at least one reference wheel set1, and preferably a plurality of reference wheel sets1, including time reference snails and/or stars, and particularly a minute snail, a quarter snail and an hour snail190.

This striking mechanism100also includes at least one strike drive wheel set2, as explained in particular in the chapter on ‘Clock Watches’ in ‘A Guide to Complicated Watches’ and visible, in particular, inFIG. 40of this book. This strike drive wheel set2conventionally includes a detent ratchet22and a repeating rack pinion24.

Striking mechanism100cooperates with a movement200, which drives the reference wheel set(s)1, and a specific output3of which is illustrated in the Figures, in the non-limiting form of a star130for releasing the strike by the movement, fitted onto a cannon-pinion, and including four teeth, in order to lift, at each quarter hour, an intermediate lever for release by the movement, referred to hereinafter as gathering pallet70.

Striking mechanism100includes at least one pivoting part, which is arranged to cooperate indirectly, via this gathering pallet70, with the output3of movement200, and particularly includes a feeler arm for reading such a reference wheel set1and a rack for driving repeating rack pinion24. One of these pivoting parts is an hour-rack20arranged to cooperate with the hour snail190. Striking mechanism100further includes a main click85, which is arranged to be set in motion upon each passing strike, and to drive, when possible, detent ratchet22.

Striking mechanism100according to the invention includes all or part of the main strike modes: grande sonnerie, petite sonnerie, alarm, silent, and more particularly includes a minute repeater mechanism, particularly a minute repeater mechanism, notably as explained in the ‘Minute Repeater’ chapter of ‘A Guide to complicated watches’.

The non-limiting variant illustrated by the Figures includes three strike modes: grande sonnerie (GS), petite sonnerie (PS), silent (S), and a minute repeater. This minute repeater mechanism includes, in particular, an hour-rack20, arranged to cooperate via a feeler arm29comprised therein, with an hour-snail190.

Striking mechanism100includes a mode selector mechanism9. This mode selector mechanism9comprises a user-accessible selector96which allows the user to choose which strike mode to use, and which controls the angular position of at least one cam90.

Mode selector mechanism9includes at least one cam90, which may have as many specific positions as there are designated modes of the striking mechanism, as in the variant illustrated by the Figures, or which includes positions specific to only some of these modes. The illustrated variant represents a flat cam90, which includes three notched portions each corresponding to one of the selectable modes:93petite sonnerie,94grande sonnerie,95silence.

More particularly, according to the invention, the notched portions are notches of variable size, requiring increasing force in one of the two directions of operation. More particularly, one particular notch, for example a central notch, is larger than the end notches, to ensure safety by preventing the user from inadvertently changing from one strike mode to another.

Cam90occupies particular positions for the different modes. This cam90has a continuous, external, feeler arm support profile98, which is arranged to cooperate with a beak61comprised in a silencing lever60. This external profile98includes an area of larger radius98S corresponding to silent mode, which is arranged to orient silencing lever60into a position where a main arm64of silencing lever60moves main click85away from detent ratchet22, in order to disable every passing strike in silent mode.

It is understood that the invention is suitable for selection of an even higher number of distinct modes, in particular when a distinction has to be made between different tunes played, for example in order to differentiate between the quarters struck, or the different gongs played, as in European Patent Application No. EP2947523B1 by the same Applicant, when incorporating an alarm mechanism according to European Patent Application EP15190808.4 by the same Applicant, a safety mechanism for selection and/or release of a strike or tune according to European Patent Application No. EP15168700.1 by the same Applicant, a tune selection mechanism with an uncouplable lifting piece according to European Patent Application No. EP15183110.4 by the same Applicant, or a carillon striking mechanism according to European Patent Application No EP16206572.6 by the same Applicant.

Cam90can thus include multiple notches: GS tune A, GS tune B, PS tune A, PS tune B, S, and/or also: GS gong A, GS gong B, PS gong A, PS gong B, S. When there are too many different modes for a single cam, mode selector mechanism9can include a plurality of cams90, especially superposed cams, each relating to some of these modes, for example with a particular tune, or a particular gong, or otherwise.

Such an arrangement makes it possible, in particular, to distinguish between the strike modes by the tunes played and/or by the gongs used. For example, grande sonnerie mode corresponds to a first tune and/or a first set of gongs, and petite sonnerie mode corresponds to a second tune and/or a second set of gongs.

It is understood that different cams90can be superposed, especially coaxially, or juxtaposed in one plane, and especially arranged in series.

In addition to mode selection, intended to ensure that only one mode selected by the user is performed by striking mechanism100, mode selector mechanism9disables the striking mechanism in silent mode by moving the clicks away from strike drive wheel set2, and prevents access by the hour-rack to the corresponding snail.

In particular, striking mechanism100includes a minute repeater with a minute repeater control device4including a repeater click40, which is arranged to drive detent ratchet22once said hour-rack20has performed a reading on hour-snail190. And, in silent mode, the main arm64of silencing lever60allows repeater click40access to detent ratchet22, provided the energy available is sufficient to complete a striking function.

In a particular embodiment, striking mechanism100includes a grande sonnerie mode for the passing strike of each hour and of each quarter hour, repeating the hour at the quarter hour, and a petite sonnerie mode for the passing strike of each hour and of each quarter hour without repeating the hour at the quarter hour. Striking mechanism100thus includes a petite sonnerie lever80, which is arranged to cooperate by bearing on a cam pin97comprised in cam90of selector mechanism9, in order, when the petite sonnerie mode is selected, to orient petite sonnerie lever80into a position in which the latter prevents hour-rack20from moving towards hour snail190, to prevent the hour being struck at the quarter hours.

When, in this same arrangement, the grande sonnerie mode is selected, cam pin97orients petite sonnerie lever80into another position in which the latter allows hour-rack20to move towards hour-snail190, to allow the hours to be struck automatically on the quarter hours.

To distinguish between the passing strike of the hours and the quarter hours, striking mechanism100advantageously comprises, coaxial to a four-tooth star130driven by output3and which is arranged to automatically release strikes on the quarter hours, a tear-shaped hour cam131, comprising a tip132which is arranged to lift petite sonnerie lever80and to allow hour-rack20to move towards hour-snail190.

The operation of mode selector mechanism9does not hinder operation of the minute repeater, and especially in silent mode, except when, advantageously, striking mechanism100includes a particular stopping function arranged to prevent any striking function being performed if the amount of energy available is insufficient to ensure that the striking function is completed: striking mechanism100then advantageously comprises a stopping mechanism5, which is arranged to prevent any striking function being performed, in order to avoid the risk presented by certain wheel sets stopping in intermediate positions, which could cause collisions on restarting. It is only when the stopping function is activated that operation of the minute repeater is also prohibited.

This stopping mechanism5is arranged to pivot a strike reversing lever59when the available energy is insufficient to complete a striking function. This strike reversing lever59controls the pivoting of a strike uncoupling lever55, which is arranged to prevent access by repeater click40to detent ratchet22when the available energy is insufficient to complete a striking function, and to move main click85away from detent ratchet22when the available energy is insufficient to complete a striking function.

Mode selector mechanism9is preferably designed to avoid the use of a notch system on the watch case, which is standard in the prior art: to this end, a selector lever96advantageously controls, particularly via an articulated connection as seen in the Figures, the pivoting of cam90, or cams90when there are more than one. More particularly, a cam jumper91, associated with a cam jumper spring92for holding it in position, includes a selector finger99, which cooperates with one of the notches of cam90. This jumper91and its spring92have a dual function: allowing the user to feel the change of notch, and providing certainty of completion of the selection manoeuvre, with return to a clear position corresponding to one of the modes, and never to an intermediate position. Advantageously, spring92is oversized to ensure safety, and especially to overcome the friction forces of the gasket in the watch case.

This cam90also includes a cam pin97, which is arranged to form a stop for a petite sonnerie lever20, whose function will be explained hereinafter. In addition to the mode selection notches, cam90advantageously comprises a continuous external profile98including at least two feeler arm support areas, arranged to cooperate with a beak61of a silencing lever60:an area of larger radius98S corresponding to silent mode, and an area of smaller radius98AGS corresponding to a stoppage in grande sonnerie mode, when the stopping function and the grande sonnerie mode exist.

Mode selection mechanism9can be used for different striking mechanisms. Its interactions with the conventional components of a striking mechanism100including a minute repeater mechanism are illustrated in a particular arrangement which is detailed below, those skilled in the art who specialize in striking mechanisms for mechanical watches or timepieces, will know how to transpose them to any mechanisms presenting variants.

This striking mechanism100is first displayed without the stopping mechanism.

FIGS. 1 and 2show the mode selector mechanism9in the indexing position corresponding to petite sonnerie notch93, which strikes the full hours on passing, and the quarter hours only on passing. The usual quarter-rack and quarter-snail are not represented, in order to simplify the explanation of operation.

Star-wheel130, arranged in proximity to reference wheel sets1, is arranged to move into cooperation, every quarter hour, with a beak72, especially an elastic beak, comprised in strike release gathering pallet70.

This quarter-rack20includes a feeler arm29arranged to feel an hour-snail190, and a rack25arranged to cooperate with a repeating rack pinion24comprised in a strike drive wheel set2. Hour-rack20further includes, set back with respect to feeler arm29, a rib23which ends, on the same side as feeler arm29, in a flat abutment portion27.

Strike drive wheel set2includes, in a conventional manner, a detent ratchet22, which is arranged to cooperate, either with a main strike click85, or a minute repeater release click40, provided with a pin41, and comprised in a minute repeater control device4, wherein this latter click40cooperates with a spring43. The pivoting of strike release gathering pallet70causes the pivoting of a lever50for release by the movement, which carries a thrust spring52, which rests on main strike click85, which is also carried by release lever50.

A conventional petite sonnerie lever80carries a banking pin82. This petite sonnerie lever80, which is returned by an uncoupling spring83fixed to a plate, includes an uncoupling beak81, which is arranged to rest on a cam pin97comprised in cam90.

Petite sonnerie lever80faces hour-rack20during the angular travel of the latter, and banking pin82is at the level of rib23of hour-rack20, on the same radius, which allows it to cooperate in abutment with flat portion27of hour-rack20, and to immobilise the latter by preventing it from reaching hour-snail190, so that the hour strike is not repeated on each quarter hour, in accordance with the operation specific to the petite sonnerie mode.

In order to ensure that the hour is struck on the full hour, star-wheel130is integral with a tear-shaped hour cam131, whose tip132is arranged to lift petite sonnerie lever80, and thus its banking pin82, to allow feeler arm29of hour-rack20to pass in order to read hour-snail190.

FIGS. 3 and 4show mode selector mechanism9in the indexing position corresponding to grande sonnerie notch94, which strikes the full hours on passing, and repeats the hour and strikes the quarter-hours on passing. The usual quarter-rack and quarter-snail are not represented. Cam pin97bears on petite sonnerie lever80at a greater distance from the end of uncoupling beak81than in the case of the petite sonnerie, and consequently banking pin82is no longer at the level of rib23, or of flat portion27of hour-rack20, but is at the level of recess28, which allows hour-rack20to pivot freely towards hour-snail190at every quarter hour.

For operation in silent mode, striking mechanism100includes a grande sonnerie and petite sonnerie isolator, hereinafter referred to as silencing lever60, which includes, at a first end, a reading beak61arranged to cooperate with one of peripheral areas98of mode selection cam90, and at a second end62, a main arm64, which is arranged to stop a main click pin86, comprised in main strike click85. This silencing lever60includes, in its median part in proximity to its pivot, a silencing pin63.

Spring65constrains silencing lever60via pin63, so that the lever is always in contact with cam90via its beak61. When the selected mode is silent mode, this silencing lever60pivots and its part62moves to disconnect click85from ratchet22. Cam pin97is in contact with uncoupling beak81of petite sonnerie lever80. During a minute repeater function (in petite sonnerie mode), a lever (not represented in the Figures) forms the link between control device4and the hole in lever80, so that hour-rack20can fall onto hour-snail190of component1.

Silencing lever60is seen inFIGS. 5 to 11, which also include a stopping mechanism5, which essentially comprises a strike uncoupling lever55. Striking mechanism100thus includes silencing lever60and strike uncoupling lever55, which are partially superposed and each arranged to hinder access by a specific click to ratchet22of strike drive wheel set2. Indeed, strike uncoupling lever55includes a stop arm56, which is arranged to stop a repeater click pin41, comprised in a minute repeater release click40, of minute repeater control device4.

The Figures show the particular arrangement of main click85and of minute repeater release click40, which are both located on the same side of strike drive wheel set2and its ratchet22, between mode selection cam90and ratchet22. This arrangement is particularly advantageous, due to its particularly reduced volume and the short distances between the various components, which means that stiffer levers can be used, and it allows for the design of a stopping mechanism which is both compact, reliable and efficient. This arrangement is made possible, in particular, by the insertion of release lever50between the gathering pallet or first strike release lever70, and main click85: this release lever50carries the articulation of main click85, and includes spring52which pushes on the click; it allows main click85to be positioned on the same side as minute repeater release click40with respect to ratchet22, it reverses the direction of pivoting of main click85compared to a standard assembly in which the latter is meshed directly in gathering pallet70, and, in particular, allows energy to be saved by precisely managing the engagement and disengagement of main click85with respect to ratchet22. More particularly, main click85and minute repeater release click40are substantially aligned as a result of this novel arrangement, and silencing lever60and strike uncoupling lever55can be superposed, in an almost collinear manner, which considerably simplifies the control and stopping of the striking functions, by reducing the number of components and the manoeuvring travels of these components.

FIGS. 5 and 6show mode selector9in the indexing position corresponding to silent mode notch95, wherein the petite sonnerie and grande sonnerie mechanisms are uncoupled, but wherein it is possible to operate the minute repeater. Reading beak61of silencing lever60is resting on the largest radius98S of peripheral shoulder98of cam90, and consequently, on the one hand, petite sonnerie lever80is stopped by cam pin97and by spring67, and on the other hand, main arm64of silencing lever60is in its farthest position from strike drive wheel set2, and stops main click pin86. On the other hand, strike uncoupling lever55is very close to strike drive wheel set2, since there is nothing to obstruct this end position, and consequently minute repeater release click40is not hindered and can access detent ratchet22, and the minute repeater can thus be operated as desired by the user,

FIGS. 7 and 8illustrate a stoppage in grande sonnerie mode and show mode selector9in the indexing position corresponding to grande sonnerie notch94. Stopping mechanism5is arranged to uncouple all the clicks, when the amount of available energy, in the barrel(s) or suchlike, is insufficient. This time, reading beak61of silencing lever60is resting on the smallest radius98AGS of peripheral shoulder98of cam90, and, at its second end62, main arm64of silencing lever60is in its closest position to strike drive wheel set2, and cannot stop main click pin86. On the other hand, strike uncoupling lever55is in its furthest position from strike drive wheel set2, and consequently hinders both main pin86of main click85and repeater click pin41, thus main click85and minute repeater release click40are hindered and cannot access detent ratchet22. The minute repeater cannot be activated by the user. No striking function can therefore be activated. There is nothing to prevent mode selection lever96being moved into another position.

FIGS. 9 to 11illustrate stoppage in silent mode and show mode selector9in the indexing position corresponding to silent mode notch95. These Figures show an operating bolt59for the articulated control of strike uncoupling lever55. Reading beak61of silencing lever60is resting on the largest radius98S of peripheral shoulder98of cam90, and the main arm64of silencing lever60is in its furthest position from strike drive wheel set2, and stops main click pin86. Strike uncoupling lever55is also in its furthest position from strike drive wheel set2, and hinders repeater click pin41. Thus, main click85and minute repeater release click40are hindered and cannot access detent ratchet22.

It is clear that the stopping mechanism is only active when there is not enough energy and that, otherwise, this stopping mechanism is disconnected.

FIGS. 13 to 19illustrate a first variant of the striking mechanism combining strike selection and mode selection according to the invention, allowing a first tune to be played in petite sonnerie mode, and a second tune, different from the first tune in grande sonnerie mode.

FIGS. 20 to 29illustrate a second variant of the striking mechanism combining strike selection and mode selection according to the invention, wherein one or the other allows the first tune or the second tune to be played, in each strike mode.

It is understood that the only limitation is that of available space inside the watch or the musical timepiece: these first and second variants are each presented here with two tunes, but it is understood that the striking mechanism could play more tunes, or differentiate between the tunes on different sets of gongs or chimes, in combination with the teachings of European Patent No EP2947523B1 by the same Applicant, and European Patent Application Nos EP15190808.4, EP15168700.1, EP15183110.4, and EP16206572.6 by the same Applicant, the details of which are not repeated here. Likewise, mode selection can be performed by coaxial cams and/or juxtaposed cams in one plane.

The first variant includes a tune selection cam101, which cooperates with a first tune lever103and a second tune lever104, which in turn cooperate with a tune selector106, arranged to control the different gathering pallets107. Each of these levers103and104includes an intermediate feeler beak, which runs over the periphery of tune selection cam101. Tune selection cam101includes a pin1010, which drives fork1050of a tune selection feeler arm105, one of whose fingers1051cooperates with the periphery of a tune selection-by-mode cam102. The latter is in the same plane here as tune selection cam101.

The second variant includes, in a similar manner, a first tune lever103and a second tune lever104, which cooperate in turn with a tune selector106, arranged to control the various gathering pallets107.

Mode and tune selection is controlled here by a control wheel set110which includes several cams stacked one on top of the other.

At the lower level, a first cam111is similar to the cam90presented above, and includes jumper notches112, and control of the petite sonnerie, grande sonnerie and silent modes by its peripheral contour113, followed by a beak1090of a passing strike isolator109, arranged to prevent any interference between a minute repeater function and a passing strike.

Each of levers103and104includes an intermediate feeler beak, which runs over the periphery respectively of a first cam114controlling the first tune and a second cam115controlling the second tune.

This control wheel set110is extremely compact and uses less height space than strike wheel set2.

It is seen that these different variants use many common components, which reduces production costs that are always high for large complications. The invention therefore provides the possibility of creating a wide variety of differentiated striking functions, either controlled by the watch or timepiece movement200for automatic striking, for example day/night, AM/PM, weekly non-working days, or otherwise, or controlled by a user as he sees fit.

The invention also concerns a watch1000comprising a movement200including an output3for releasing a passing strike function by the movement, this movement200being arranged to drive at least one reference wheel set1, and watch1000includes at least one such striking mechanism100.

The invention also concerns a timepiece2000comprising a movement200including an output3for releasing a passing strike function by the movement, this movement200being arranged to drive at least one reference wheel set1, and watch2000includes at least one such striking mechanism100.
