Description

Technical area

The present invention relates to a control and adjustment device for a mechanical watch module. The invention is particularly suitable in particular for mechanical wristwatches type watch alarm clock.

State of the art

Adjusting devices based on crowns and drawbars are known, which make it possible to determine different functions of the rotation of the crown as a function of the position of the pull tab.

The document EP2012199 discloses for example a function control device and / or time indications advantageously using a rotating bezel to select the indication to be adjusted, and a controller for the functions or time indications selected. The control member has a degree of freedom in rotation for the adjustment, but also requires another degree of freedom in axial translation by which it is connected desmodromic with a cam having a profile with 2 state levels 0 , 1 respectively corresponding to a state of adjustment and a state of no adjustment.

Also known are control devices for chronographs using column wheels, in which the push button function can determine different modes of operation of the chronograph.

The disadvantage of this type of control mechanisms and adjustment is that it is not possible for the user to be aware of the current operating mode, on the one hand, which makes the navigation between the modes relatively impractical and can also give rise to handling errors.

Furthermore, in electromechanical watches, there are known watches with which different modes are selected using a first control member, often a pusher, and the setting of parameters is done using one or more other pushers. This kind of mechanism has the advantage of proposing a more intuitive navigation, but is however not applicable to movements or mechanical modules, for which the adjustment involves many dedicated control members, arranged at different places on the middle of the watch. This size also prevents easily integrate additional modules on the plate, for lack of space.

Brief summary of the invention

An object of the present invention is to provide a new device and a new control method for a watch module free from the limitations of the known prior art, which allow a more convenient use and a smaller space on the platen.

These aims are achieved in particular by means of a watch module containing a barrel, a control member, an adjusting member and mechanical display means, the control member enabling the selection of the modes of operation of the watchmaking module, the control means display comprising first display means coupled to the controller for displaying the current operating mode, the controller fulfilling at least 3 distinct functions according to the selected operating mode, characterized in that the control member is coupled to a pawl meshing with a 5-stage column wheel, a first stage of said column wheel controlling said first display means, a second stage controlling the pivoting of a release arm for activation and deactivating a gear train powered by said barrel, a third stage controlling the position of a pull tab associated with the adjusting member, and a fourth stage controlling the position of a flip-flop which directs the gear of said adjuster to a first kinematic chain or a second kinematic chain for setting a first or second time parameter separately.

An advantage of the proposed solution is to couple the adjustment and control members, so that a single adjustment member can perform several functions, which frees room on the plate for other watch modules.

Furthermore, the instantaneous display of the current mode makes it possible to determine the function performed by the adjustment member. The proposed solution thus allows a simple and fast adjustment, dispensing the use of any electronic part and while remaining particularly user-friendly thanks to the instantaneous visualization of the operating modes during the adjustment steps.

An additional advantage of the proposed solution is to have dedicated adjustment and control members, so that the use is much more intuitive. Moreover, since the adjusting member has only one axial position, whatever the mode of operation chosen, its use is facilitated over traditional pull mechanisms, for which changing the mode requires tedious operation. of the crown.

Example (s) of Embodiments of the Invention

The figure 1 illustrates the dial and the caseband of a watch 101 completely mechanical, that is to say whose housing contains no electronic component for any activation or display function. The watch 101 is an alarm clock provided with an alarm device, comprising a barrel as a source of energy 93, further illustrated by the Figures 8A and 8B , and several crowns 103,105 and pushers 102,104. A first pusher crown pair 105, 104 is associated with the basic movement of the clock watch 101, while a second pusher crown pair 103,102 is associated with the alarm device. The alarm device controlled by the pusher 102 and adjusted by the ring gear 103 consists of a preferred embodiment of the invention, more generally relating to a watch module, and which applies here to the alarm module, distinct from the basic movement. According to this preferred embodiment described below, the watch module is thus a module comprising a barrel, a control member, an adjustment member and display means, constituted according to the preferred embodiment described hereinafter by first means associated with the display of the operating mode of the watch, formed by the elements 23, 23 'and 108 described below, second display means subdivided between those dedicated to setting a date value of triggering the alarm, formed by the elements 109,109 ', 109 "described below, associated with the first setting time parameter that constitutes here the trigger date 109', and those 110,110 ', 110", 110 "' dedicated to setting the alarm trigger time, which is a second time setting parameter.

The alarm module described below allows, according to this preferred embodiment, the actuation of a ringing device, but it could also actuate a vibrating alarm, that is not necessarily generating intrinsically a sound. It will also be understood that the setting of two distinct time parameters with the same adjustment member 103 could be applied to other types of parameters.

On the dial of the watch, one can distinguish, from the center, the needles of the movement of the watch, namely the hour hand 106, that of minutes 106 'and that of seconds 106. At three o'clock there is a aperture 107, through which we can view the date, formed by a disassociated display tens 107 'and 107' units, tens and units on separate disks having their own drive means, the cross 14 and the wheel 15 illustrated in the following figures, and in particular the Figures 2A, B, C and 9 A, B , CD .

At nine o'clock on the dial is an annular scale containing inscriptions corresponding to date values 109. A needle 109 points to a date value chosen for the trigger 109 ', which will determine the day of actuation of the device. On the inner face of the ring formed by the annular scale 109 "is a window 108, which displays the operating mode of the alarm clock. On the figure 1 , the mode displayed by the icon corresponds to the D mode of deactivation of the alarm device; as will be seen later, particularly on the basis of Figures 8A and 8B showing the display disk 23 'of the modes in its entirety, the clock watch described hereinafter contains 4 distinct operating modes A, B, C and D, respectively corresponding to an engaged state A, a date adjustment mode of triggering B (visualized with the aid of the needle 109), a mode of setting the triggering time C, visualized in the counter 110 situated at 6 o'clock on the dial, and in which a 110 "ring carrying time indications related to the triggering of the alarm device, accurate according to the mode of described in steps of a quarter of an hour, and the deactivation mode D, in which the alarm can not be started. The hour value chosen during the setting of the alarm is displayed in the middle of the window 110 ', either by a numerical value, or by half-hour or quarter-hour indications, distinct from each other, the indications of quarter of an hour being smaller than those half-hour to allow an intuitive reading. Other types of display can however be envisaged as long as they allow a reading and thus easy verification of the alarm setting time 110 '. The scrolling through the window 110 is preferably done step by step, by means of an indexing element 111 acting on the ring 110 ", the person skilled in the art will understand that it is possible to adjust this step to a value less than fifteen minutes, or alternatively to use a trailing display for the desired trigger time value 110 'having two specific indication means, formed by the needle 109 and the disk 110 ", arranged in two different places of the dial, allows an easy and intuitive reading of each setting parameter. Moreover, the dissociated display with two different types of indicators, the needle as opposed to a ring, also makes it easy to differentiate the parameters when reading the values to be adjusted.

The middle part of the clock watch 101 carries two push-buttons 102 and 104. The push-button 104 makes it possible to correct the date values, in unit increments each time the push-button 104 is pressed. The correction of the date, as well as the coupling of the movement of the base which allows the display of the current time by the hands 106, 106 'and 106 ", are explained in detail with the help of Figures 9A, B , CD . The pusher 102 is itself a control member, which allows each pressure on the pusher 102 to change the display in the aperture 108 by means of a specific wheel, described below in particular with the help of Figures 6A, 6B , 7A, 7B and 8A, 8B . According to the preferred embodiment described, the change of mode causes the rotation of a display disc 23 'comprising 4 different icons, two of which are associated with the setting of time parameters, here the date 109' and the time 110 ' trigger, and two others on activation or deactivation of the alarm. It will be understood from reading the foregoing that the control mechanism for change of mode and setting parameters of the wakeup watch 101 described could be replicated to other types of watch modules, requiring for example the setting of other distinct time parameters (hours, minutes, moon phase for example) for a possibly different function, such as a countdown or the triggering of a chronograph mechanism.

Each time the pushbutton 102 is pressed, each mode change also has an influence on the function of the adjusting ring 103, which alternatively enables a ringing barrel 93 to be raised, illustrated further in particular on the Figures 8A, 8B , to adjust the date value 109 'or to adjust the value of the triggering time 110'. It is thus understood that the function of the ring 103, which acts as a control member as opposed to the push button 102 which acts as control member, changes according to the selected mode. The members 102 and 103 are thus coupled, and allow a particularly intuitive adjustment and actuation of the alarm device thus described, since the entry in each adjustment mode, calendar or time, can be viewed simultaneously, and that each pressure on the pusher is then followed, for the actuation of the alarm device, with an adjustment step. Considering the winding of the barrel as a setting step of the alarm device, it can be noted that the actuation of the alarm is effected by means of the succession of three stages of alternation of a pressure of the pusher, and rotation of the crown 103, to wind the barrel, set the date, and adjust the schedule. This succession of steps can be done in any order, ie not necessarily starting with a determined adjustment step; however, the succession of modes is, in the embodiment described, in a given order, namely: A, D, B, C. The winding of the ringer barrel 93 is possible in modes A and D; in which the alarm is respectively activated or deactivated. The triggering step of the alarm device A1, illustrated on the figure 3A consists in pivoting the release arm 10 by pressing the pushbutton 102 after setting the alarm 110 'alarm time. In doing so, the user of the alarm clock 101 enters the alarm activation mode A.

The advantage of using such a ring 103 as adjusting member makes it possible to adjust the chosen time parameters in any direction, that is to say incremental or decremental. The differentiated position of the various triggering values of the alarm for the date 109 'and the time 110' also allow an intuitive sequential adjustment in which one can instantly view the set value. The simultaneous display of the operating modes, including the two adjustment modes B and C, help to make the adjustment and visualization of the time parameters to be set more convenient. Moreover, the arrangement of the display of the trigger date value 109 'opposite the calendar of the basic movement formed by the indications of tens 107', and units 107 ', the indications being arranged respectively at 9 o'clock and 3 hours on the dial, allow a very fast comparison of these date values and therefore easy reading, the choice of a different display mode by needle 109 for triggering the alarm and by digital display for the date current also makes it possible to avoid any confusion about the interpretation of the displayed date values.The numerical value will give without effort the desired indication of the current date, which is the one most often consulted by the user on which he is working. will first focus spontaneously.

The alarm clock of the figure 1 Finally, it contains another ring gear 105, which makes it possible to raise the barrel of the basic movement driving the clockwork and the needles 106, 106 ', 106'', or to adjust these hands, The function of the ring 105 is preferably determined by the position a zipper, which however only needs two positions here since the calendar is set using the push button 104.

The Figures 2A, B and C illustrate the triggering device of the alarm module according to the preferred embodiment described in different views, the first in perspective, the second in section and the third view from above. The alarm consists according to this embodiment in a ringing device, therefore containing a ringing hammer 9 acting on a sound element 92, here a stamp, but this sound element could also take the form of a bell or a bell. any other type of sound element. Although not illustrated in this figure, and as will be seen later in view of Figures 8A and 8B , the alarm device also comprises a ringer barrel 93 and a ringer anchor 91, so that the ringer can continue for a time, at the convenience of the manufacturer of the alarm clock. The frequency of the repetitions, the duration of actuation of the ringing device, and the intensity of the sounds emitted depends on the energy available in the ringing barrel 93, ie the moment of inertia that it provides to the mobile phone. ringtone (not illustrated but doing exhaust wheel office distributing the energy of the barrel to the ring anchor), and the moment of inertia of the ring hammer 9. We can configure these parameters so that the ringing lasts about a minute. According to the preferred embodiment illustrated in the figures, the ringer anchor 91 is integral with the ringer hammer 9.

On the Figures 2A and 2C the motor means of the units 107 "and 107 'of the date can be distinguished according to one of claims 2 or 3, which conventionally consist respectively of a wheel 15 having 10 teeth and a cross 14 having four branches. a disk having the values of date units 107 "while the cross 14 drives a disk having the values of tens of days 107 '. The cross 14 and the disc 15 are indexed by respective elastic indexing elements 14 'and 15'; the gearing of the elements 15/15 'and 14/14' taking place on different planes. The wheel 15 meshes with a first date wheel 11 driven by the base movement, which drives in parallel a series of 4 teeth 13 on a slightly lower plane for the indexation of the tens of calendars and the passage from 31 to 1. Each of the 4 teeth meshes on the cross 14 tens. There is also, on a still lower floor, another date wheel 12 meshing with the date of expiration wheel 2 of the alarm device according to the invention, which constitutes a first element of triggering means (references 2,2 ', 3,3', 4,4 ', 5,6,6', 6 ', 7,7', 8,8 ', described below on the basis of Figure 2A ). These triggering means are not only associated with a date value 109 ', but also with a triggering time 110'. These triggering means comprise a date trigger element 4 and a time trigger element 6, each distinct and each armed with a spring 4 ', 6'. The triggering element 4 allows the vertical movement of a first triggering wheel 3, associated with the date, with respect to the date deadline wheel 2, coupled to the watch module via the date wheel 12. According to FIG. a variant, it would be possible to directly use the date wheel 12 as the deadline wheel of date 2, this however poses a particular machining problem of this wheel, which must include orifices or protruding elements, as it is will see later, and integration constraints to the calendar program wheel, formed by several superimposed wheels and in particular as regards the height. The first triggering wheel 3 is pressed onto the date-deadline wheel 2 by the triggering element of date 4, and the first trigger wheel 3 contains recesses 3 'to allow the penetration of pins 2' of the date of maturity wheel 2 at the time of tripping. It is understood here that the recesses and / or lugs 2 ', 3' cooperate mutually and that their positions could be reversed on each of the wheels 2 and 3.

The triggering means of the alarm device described (references 2,2 ', 3,3', 4,4 ', 5,6,6', 6 ', 7,7', 8,8 ', 10 on the Figures 2 to C and the following) comprise a second trigger wheel 7 pressed onto a clock wheel 8 by the time trigger element 6, which allows the vertical movement thereof, as well as the trigger element 4 for the first trigger wheel 2 The clock wheel 8 is coupled to an hour wheel of a clock movement 1061, 1061 ', illustrated later in the drawings. Figures 9A to D . Similarly to the wheels 2 and 3, the second trigger wheel 7 and the clock wheel 8 comprise recesses respectively cooperating pins 7 ', 8' respectively. The protruding parts could however be arranged on one or the other of these wheels. The first and second trigger wheels 3,7 are kinematically connected to one another via the calendar trigger element 4, taking the form of a potentially resilient lever, one end of which is arranged under one end. release bridge 5 secured to the second trigger wheel 7. The illustrated triggering means comprising a time trigger element 6 in the form of a preferably elastic lever, a first end of which is fixed to the second trigger wheel 7, and provided with at a second end of a first gripping element 6 "engageable in a second gripping element 9 'of the striking hammer 9. The respective gripping elements of the hammer 9' and of the triggering element 6 are particularly visible on Figures 2B and 2C . They may take any form suitable for stalling or permanent restraint; according to the preferred embodiment, preferred male / female elements that could be arranged indifferently on the hammer 9 or the time trigger element 6. Any other trigger mechanism for releasing the ring anchor 92 to the date 109 'and In the time zone 110 'determined for the alarm, for example by means of a rocking mechanism, could also be envisaged alternately for the arrangement of the triggers 4,6.

As can be seen from all FIGS. 2A, 2B, and 2C the alarm device comprises a release arm 10, which makes it possible to arm and disarm the ringing device. The release arm 10 is disposed below the release bridge 5, as will be seen in the following figures 4 having attraction to the adjustment functions, in all modes except the mode A of engagement of the alarm, which is the mode in which is the alarm device for Figures 2A, B and C illustrated. In this mode, the arm is thus in an unobstructed position, which will allow, as will be seen in the following figures 3 A, B and C, the vertical movement of the wheels 2/3 and 7/8 relative to one another. . The release arm 10 also comprises a heel 10 'cooperating with a control cam described with the column wheel 22 on the basis of the Figures 6 to 8 . The column wheel 22 serves as a control device for the arm 10, via the cam located on the floor 224 visible on the Figures 6 to 8 following, and the release of the arm 10 is caused by an action on the push button 102. As discussed below, the column wheel 22 determines the operating modes A, B, C, D of the alarm device; the clearance of the arm 10 corresponds to the entry into the mode A and the activation step of the alarm device A1, and vice versa, when the arm 10 is released, that is to say when is in this mode A, the engagement of the arm 10 corresponds to the entry into the deactivation mode D and the action on the pusher 102 to enter this mode corresponds to the deactivation step D1. These steps A1 and D1 are visualized by arrows on the Figures 3A, B, C . Although according to the embodiment described, the release arm 10 is used to activate and deactivate respectively a ring module, it will be understood that this release arm 10 could be used to deactivate any type of gear powered by a barrel.

The Figure 2B shows also a third date wheel 16, and an associated indexing element 16 '. The third date wheel 16 is used for the correction of the current date value with the aid of the push-button 104. This correction will be explained later on the basis of the figures 9 A to D.

The Figures 3 A to C show the alarm device in the same mode of engagement of the ring, with all the same elements as those illustrated in the Figures 2A, B, C previous and according to the same views as the figures 2A, B, C previous, but at the moment of the ringing. The trigger occurs "in cascade" with respect to each of the triggers associated with each trigger parameter, namely in this case first the date, then the time chosen for the alarm. When the chosen date 109 'is reached, the first trigger wheel 3 sinks on the date deadline wheel 2, in a vertical movement illustrated by the arrow A2. Simultaneously, the calendar trigger element 4 also decreases, according to the arrow A4. Once this step is performed, when the chosen time 110 'is reached, the second trigger wheel 7 sinks on the date deadline wheel 2, in a vertical movement illustrated by the arrow A4. Simultaneously, the time trigger element 6 also lowers, according to the arrow A5, thus releasing the hammer 9 and causing the ringing. When the current date is no longer equal to the trigger date value 109 ', the lugs of the date expiry wheel 2' push back the first trigger wheel, and similarly when the current time is not more equal to the hourly trigger value 110 'the lugs 8' of the hourly wheel expel the second trigger wheel, so that the device is found in the position illustrated in FIGS. Figures 2A, B, C preceding. Thus the alarm is no longer triggered not only for a particular schedule, but also for a particular day. Repetition takes place only when these two conditions are met, ie at most once a month.

This cascade mechanism makes it possible to envisage, although this variant is not described in detail or illustrated, to add an additional trigger stage for a monthly deadline, or a year-end, by coupling a third wheel of triggering a wheel of maturity of the months, or even a fourth a tripping wheel to a year-end wheel (unit wheel from 0 to 9), or other temporal parameters.

The control of the alarm device according to the preferred embodiment illustrated may comprise a deactivation step D1 of the alarm device, corresponding to the activation of a specific deactivation mode D by pressing the pushbutton 102. This step D1 deactivation, can be performed at any time, regardless of the effective triggering of the alarm device, the oscillation frequencies of the hammer 9 and the arrangement of elements 6 "of the calendar triggering element 6 and the hammer 9 'allowing the instantaneous stopping of the ring when mode D is activated even when the ring is operating. according to the scrolling order of the clock watch 101 modes, at a pressure on the push button 102 while the current operating mode is the alarm activation mode A, represented by the ringtone icon in the wicket 108. The deactivation mode D corresponds to the display of a crossed-out ringing icon in the window 108, as on the figure 1 .

For the description of the following figures, 4 A, B, C, A, B, C, A, B, A, B and A, B, the triggering means, identical in all respects to those described in FIGS. Figures 2A, B, C will not be repeated in detail, the references in the figures allowing a clear understanding in view of the references and explanations provided for Figures 2A, B, C .

The Figures 4A, B and C illustrate the triggering device of the alarm according to the preferred embodiment described according to the same views as the trilogies of figures 3 previous, the first in perspective, the second in section and the third view from above, but this time during mode B of setting the value of the trigger date 109 'of the alarm device. In this operating mode, and as for the clock setting operation mode C and the alarm device deactivating mode D, the release arm 10 is placed under the release bridge 5 next to the trigger wheel hour 7, so that it is blocked horizontally and can never lower. Thus, the time trigger element 6 can never release the hammer 9 and thus prevents the wheel from setting the ring. The setting wheel of the first trigger wheel 3 is detailed on the Figures 4A and 4C , the figure in section does not allow an explicit illustration.

The setting wheel of the trigger date 109 'comprises a first wheel 31 provided with a pinion 31', which meshes with a second intermediate wheel 32 returning meshing with the third wheel 33 driving the display needle 109 of the date trigger, located on a higher plane. The rotation of the third wheel 33 is indexed by date unit thanks to the elastic indexing element 33 '. The number of the teeth of the wheels 33, 32, 31 ', 31 and 3 is chosen such that the angle of rotation of the third wheel 33 is exactly transmitted to the first trigger wheel 3 so that these the last ones work in a fully synchronized way. To do this, it is for example possible to choose an equal number of teeth for the wheels 33 and the pinion 31 ', as well as for the wheels 31 and 3. The wheels 33 and the pinion 31' will thus have the same angular velocity of same as the wheels 31 and 3; since the first wheel 31 and the pinion 31 'are also the same, by transitivity that of the wheel 3 will be equal to that of the third wheel 33. The wheel is then extended by the fourth and fifth wheels 34 and 35, the fourth wheel 34 meshing on the third wheel 33 and the fifth wheel 35 meshing on the wheel 34. The fifth wheel 35 then meshes on a rocking wheel 2522, the second starting from the ring 103, which itself meshes on a first wheel of flip-flop 2511 located on the same flip-flop 251, which is oriented differently according to the operating modes, and more precisely between the operating modes B and C which are adjustment modes. In the case of the operating mode B of the setting of the trigger date value 109 ', illustrated by the Figures 4A-C this flip-flop is directed towards the date adjustment wheel formed by the elements 31-35 described above. The first rocking wheel 2511 finally meshes with the adjusting wheel 26, common to the two adjustment modes B and C, and which meshes with a sliding pinion formed of a first coupling gear 241 meshing with the adjusting wheel 26, and a second coupling gear 242, provided with a Breguet gearing for unidirectional gearing, conventionally used for winding the striking barrel 93. The position of the sliding pinion formed by the first and second coupling gears 241,242 of the rod of the 1033 adjustment ring is determined by the position of a coupling lever 24, which is illustrated further including using the Figures 6A , B to 8 A , B . Finally, it is possible to distinguish the wheel from the adjusting ring 1031 at the end of the rod 1033, which is actuated in rotation by the user by turning the ring gear 103. The setting wheel of the trigger date 109 'forms a first kinematic chain on which can mesh the flip-flop 251.

The Figures 5A, B and C illustrate the triggering device of the alarm according to the preferred embodiment described according to the same views as the trilogies of the figures 4 previous, the first in perspective, the second in section and the third view from above, but this time during mode C setting the trigger time 110 'of the alarm device. In this operating mode, and as for the operating modes B of setting of the disarming time and D of the alarm device, the disengagement arm 10 is disposed under the disengagement bridge 5 next to the hourly trigger wheel 7, so that it is blocked horizontally and can never lower. The clearance bridge 5 is shown on the Figures 5A and 5B but it is not visible on the Figure 5C on which we clearly see the spacing between the trigger wheel 7 and the hourly wheel 8, but not the clearance bridge 5 above the time trigger element 6, above which we see the ring 110 " bearing the time indications.

The Figure 5A illustrates in perspective the time setting wheel 110 'trigger, comprising a first wheel 71 of the adjusting wheel of the second trigger wheel, meshing directly with the second trigger wheel 7. This wheel 71 meshes with a second wheel the setting wheel of the second trigger wheel 72, which is engaged, upon activation of the adjustment mode C, with the second flip wheel 2512. The gear system of this second flip wheel 2512 at the the wheel of the setting ring 1031 is in all respects identical to that described for the adjusting mode B, namely a gear on the first rocker wheel 2511 located on the same lever 251, which then meshes with the adjusting wheel 26, by itself meshing with the sliding pinion formed by the first coupling gear 241, meshing with the adjusting wheel 26, and the second coupling gear 242 provided with a Breguet gearing for unidirectional gearing. ectional, conventionally used for winding the ringing barrel 93. The position of the sliding pinion formed by the first and second coupling gear 241,242 of the rod of the adjusting ring 1033 is determined by the position of the coupling lever 24, which is illustrated further including with the help of Figures 6A , B to 8 A , B , and whose position is identical for the adjustment modes B and C. The wheel of the adjusting ring 1031 located at the end of the rod 1033 is actuated in rotation by the user by turning the ring gear 103. The wheel of setting the triggering time 110 'forms a second kinematic chain on which the lever 251 can mesh.

The Figure 5A shows also a gear train to the internal toothing of the ring bearing the 110 "trigger time indication, which is actuated in stepwise rotation by the indexing elements 111 in engagement with the internal toothing. left of the figure shows an exploded view in which distinguishes the second wheel of the setting wheel of the trigger wheel 72 in engagement with a first wheel of the adjustment train of the trigger time ring 73, in the same plane, the rotation of which is secured to a second wheel the setting wheel of the trigger time ring 73 ', coaxial with the wheel 73 and located in a higher plane. The wheel 73 'meshes in the same plane with a third wheel of the setting wheel of the triggering time ring 74, the rotation of which is secured to a fourth wheel of the setting wheel of the triggering time ring 74', coaxial with the wheel 73 and located in the plane of the internal toothing of the ring bearing the 110 "trigger time indication, with which it meshes.The arrangement with coaxial wheels 73, 73 'and 74, 74' allows save space on the plate but has the disadvantage of a larger size in height.The gear ratios of the gear are determined so that a complete rotation of the ring 110 "bearing the indication trigger time is synchronized to a full rotation of the second trigger wheel 7.

The Figure 5B illustrates, in addition to the triggering means already described in detail using the Figures 2A, B, C , the same setting wheels of the second trigger wheel 7 and the time ring bearing the time indication 110 'trigger that those illustrated in the Figure 5A however, the view from above does not make it possible to determine the plane-by-plane position of the various elements of the gear train, but simply to determine the gear relationships of the various elements: 71-72-2512, forming a first kinematic sub-chain relative to adjusting the position of the second trigger wheel 7, and 72-73 / 73'-74 / 74'-110 ", forming a second kinematic sub-chain associated with adjusting the position of the ring containing the values of 110 "trigger time. The writing 73/73 'and 74/74' indicates here that the two elements referenced are coaxial and integral in rotation, but each of the elements being located on a different gear plane. We can notice on Figures 5A, B, C that the preferred embodiment illustrated uses lines on the ring 110 "bearing the time indication trigger, while this indication takes a different shape on the figure 1 . Any type of indication making it possible to clearly determine the triggering time 110 'may be indifferently chosen by those skilled in the art.

The Figures 6A and 6B illustrate views respectively in perspective and from above of the alarm device according to a preferred embodiment of the invention, with an illustration of a control device based on a column wheel 22. These figures make it possible to explain the selection modes, their implication on the position of the latch 251, their display in the window 108 visible on the figure 1 , as well as the coupling of the function of the crown 103 to the mode selected with the aid of the push-button 102. Figures 6A and 6B show the alarm device in the same mode as Figures 4A-C , that is to say the setting mode of the trigger date B. As already explained on the basis of the trilogy of figures 4 in this mode B, the position of the rocker is such that the second rocker wheel 2512 meshes with the fifth wheel of the control gear of the first trigger wheel 35. This position is controlled by a control cam of the rocker lever 25, positioned on a stage 222 of a column wheel, composed of 5 superimposed stages. The next higher stage 223 is that of the control cam of the coupling lever 24, which determines the position of the sliding pinion formed by the first and second coupling gears 241, 242. This stage consequently alternately controls the coupling of the wheel. 1032, shown on the Figures 6A and 6B contrary to Figures 4A and 4B , at the first coupling gear 241, to allow the winding of the ringer barrel 93, or the coupling of the second coupling gear 242 to be coupled to the adjusting wheel. It is therefore found that the modes in which the winding of the barrel 93 and the adjustments are made mutually exclusive, since they each correspond to different positions of the sliding pinion. The stage immediately above the stage 223 is the control stage 224 of the release arm 10, which comprises a cam acting on the heel 10 'of the release arm 10. Therefore, this stage controls the engagement and the disable the alarm. The last stage 225, located at the upper end of the stack of the column wheel 22, respectively corresponds to the mode display control, the wheel of the stage 225 meshing with the wheel 23, whose rotation is secured. to that of the disk 23 'carrying the icons indicating the operating modes of the alarm device. The wheel 23 ', not shown on the Figures 6A and 6B , is shown later on Figures 7A and 7B . For more clarity, the annular scale 109 "bearing the date indications the trigger date indicator needle 109 is illustrated only on the Figure 6B , but not on the Figure 6A . Finally the lower stage 221 corresponds to the gear stage of the column wheel 22 with a pawl 21 actuated by the push button 102, of which only the rod 1021 is shown in the figures.

• 222 : 0 = position du levier 24 permettant le remontage du barillet de sonnerie 93, engrenage des éléments 1032-241 ; 1 = position du levier permettant le réglage des paramètres de temps, engrenage des éléments 242-26;
• 223 : 0 = position de la bascule pour un engrenage sur le rouage du réglage du quantième, engrenage des éléments 2512-35 ; 1 = position de la bascule pour un engrenage sur le rouage de réglage de l'horaire, engrenage des éléments 2512-72 ;
• 224 : 0 = bras en position armée, bloquante ; 1 = bras en position dégagée (mode A du dispositif d'alarme).

As can be seen from the Figure 6A , the toothing of the lower stage 221 is arranged such that a pressure on the pusher 102, causing the movement of the rod and the actuation of the pawl 21, causes the rotation of the column wheel 22 in the anti-direction -Schedule. The stage wheel 225 thus causes the disk 23 'to rotate in the clockwise direction to scroll through the modes in the aperture 108. The gear ratios between the stage wheel 25 and the wheel 23 are determined by so that each actuation of the pusher 102, the disk 23 'mode display performs a quarter turn in the clockwise direction, causing the switch from one mode to another in the deactivated order D, setting the date B, setting of the time C, then A. In parallel with the scrolling modes, it can be seen that the cams on the 222,223 and 224 stages each have two distinct positions, with an activation model whose period is 4 By naming respectively "0" and "1" the following states for each floor:

• 222: 0 = position of the lever 24 for reassembly of the ringer barrel 93, gear elements 1032-241; 1 = position of the lever allowing adjustment of the time parameters, gearing elements 242-26;
• 223: 0 = position of the scale for a gear on the gear wheel of the date adjustment, gear of elements 2512-35; 1 = rocker position for a gear on the time control gear, gear elements 2512-72;
• 224: 0 = arm in armed position, blocking; 1 = arm in open position (mode A of the alarm device).

The overall state of the column wheel 22 can thus be summarized by the following table, in which the change of state of each stage corresponds to an angular displacement of a tooth of the lower stage 221. According to the embodiment illustrated preferential, the wheel of the lower stage comprises 12 teeth and thus 12 states are represented; those skilled in the art will understand, however, being given the periodicity noted, that a number of teeth equal to any multiple of the period can be chosen.
222: 0110 0110 0110
223: 1100 1100 1100
224: 0001 0001 0001

Reading column by column it is indeed noted that the various states of the system (010, 110, 100, 001) are repeated after incrementation of 4 teeth of the wheel of the lower stage 221; each of the 4 states corresponds to different modes of the system (010 = D mode deactivation 110 = B-mode calendar setting, the first "1" indicating that the system is in the setting mode and the ^2nd "1" indicating the type 100 = time-setting mode C, and finally 001 = switch-on mode A of said alarm device.) The activation or deactivation positions on the stages 222 and 223 cams illustrate how the function performed by the crown 103 is determined (0 = reassembly, 1 = control, with 11 = ¹ type of control and 10 = ^2nd type setting).

Those skilled in the art will understand that functional constraints can be applied to the system, for example: when the value of stage 222 is at 1, the value of stage 224 is preferably 0, so that no triggering of the alarm can not be unduly caused during the adjustment, as is the case here according to the preferred embodiment illustrated, which describes a control method in which the adjustment modes B, C and activation A are dissociated. Other constraints can be envisaged with the column wheel 22 described, which allows a number of potential modes equal to 8 (2 possible states at each stage on which cams are arranged, ie 222,223,224, at the power of the number of these stages, equal to 3).

The advantage of the use of such a column wheel 22 makes it possible to manage the states of the system from a centralized control device, whose arrangement can be determined on the plate. The fact that this control member is actuated by a single push button 102 enables the modes to be scrolled intuitively, each pressure corresponding to a mode change step. This arrangement dispenses with the use of control members dedicated to specific functions; according to the preferred embodiment of the invention, the Crown 103 fulfills 3 different functions. It will be understood by those skilled in the art that switching to different setting wheels can be applied to other independent time parameters, not just date values 109 'and hourly value 110 "combining hours and minutes.

The Figures 7A and 7B illustrate views respectively in perspective and from above of the alarm device according to the same preferred embodiment of the invention as in the preceding figures, with the illustration of the control device based on a column wheel 22, this time determining the mode C of time adjustment, that is to say the same mode as Figures 5A-C wherein the flip-flop 251 is oriented such that the second flip wheel 2512 meshes with the second wheel of the setting wheel of the second trigger wheel 72. A first major difference between Figures 5A, B and the Figures 7A, B relates to the addition of the column wheel 22, which controls the operating modes of the alarm device, as has already been explained in view of Figures 6A and 6B . On the Figures 7A and 7B , the position of the rocker control lever 25 differs from that of the Figures 6A and 6B , in that the rocker is oriented slightly more upwards to obtain the desired gear towards the second wheel of the adjusting gear of the second trigger wheel 72. This difference in orientation is particularly visible by comparing the Figures 6B and 7B for example. A second major difference between Figures 5A, B and the Figures 7A, B relates to the illustration of the mode display wheel 23 ', shown in its almost complete. All the icons being visible on the Figures 8 A and B , the detailed description of this element will therefore be made on the basis of these figures in the following description of the invention. All the other elements illustrated being identical to those of Figures 5A and B , this figure will be understood thanks to the explanations previously provided for these Figures 5A, B preceding.

The Figures 8A and 8B illustrate respectively perspective and top views of the alarm device according to the same preferred embodiment of the invention as in the previous figures, with the illustration of the control device based on a column wheel 22, this time ci in one of the modes A or D in which the winding of the ringer barrel 93 is possible. These Figures 8A and 8B also illustrate the entirety of the winding wheel of the barrel 93, which starts from the crown wheel 1031 and the coupling wheel 1032, which here is precisely coupled by a set of teeth Breguet to the first gear of coupling 241 of the sliding pinion mounted on the rod 1033, and which enables the wheel 1032 to be engaged in a determined direction of rotation, which is arranged to be that of the winding of the barrel 93, while generating no gearing in the reverse. The winding gear continues by a gear on the crown wheel 901, which itself meshes with a second winding wheel of the barrel 902 'coaxial and rotationally fixed with a first winding wheel of the barrel 902, meshing in a lower plane. The first winding wheel of the barrel 902 meshes with a third winding wheel of the barrel 903, coaxial and integral in rotation with a fourth winding wheel of the barrel 903 ', meshing in a lower plane with the fifth winding wheel of the barrel 904. , engaged with the ratchet wheel 93 "of the barrel, clearly visible on the Figure 8B . Thus when the ring gear 103 is actuated in a specific direction corresponding to that of the winding of the barrel 93, which is according to the preferential embodiment described chosen distinct from that of the base movement, so as not to reduce the power reserve during operation. actuation of the alarm device. The energy supplied in the barrel 93 will be released during actuation of the alarm device, the ring gear being engaged with the outer toothing of the barrel 93 '. The ringing device, acting as an escapement, is however not shown and only the anchor 91, integral with the hammer 9, is visible in the figures.

As already indicated previously in the description, the triggering means of the alarm device described (references 2,2 ', 3,3', 4,4 ', 5,6,6', 6 ', 7,7', 8.8 ', 10) are already explained in previous figures and will not be detailed for Figures 8A and 8C . The illustration of these tripping means next to the winding of the barrel 93 allows to appreciate their mutual positioning and the space generated on the plate. The coaxial arrangement of the first and second winding wheels 902, 902 'and the third and fourth wheels 903, 903' makes it possible precisely to reduce the space requirement in the plane of the plate.

• la cloche barrée: mode D, correspondant au mode désactivé. Ce mode peut être activé indépendamment de l'actionnement effectif de la sonnerie, comme expliqué précédemment.
• le « d » pour « day »: mode B, correspondant au réglage du quantième de déclenchement 109'. C'est le mode qui suit le mode D après une pression sur le bouton poussoir 102, auquel est liée la tige 1021, car le cliquet 21 entraîne alors la roue à colonnes 22 en rotation dans le sens anti-horaire, et donc la roue 23, auquel le disque d'affichage 23' est fixé, dans le sens horaire. Dans ce mode, la couronne 103 permet d'effectuer un réglage de la valeur de quantième de déclenchement 109'; le réglage est par ailleurs possible dans les deux sens, c'est à dire que la rotation de la couronne 103 dans un premier sens engendre la rotation de l'aiguille 109 dans un premier sens, pas à pas grâce à l'élément élastique d'indexation 33', et que la rotation de la couronne dans le sens inverse engendre la rotation de l'aiguille 109 dans le sens inverse. Cette fonctionnalité permet d'augmenter considérablement l'aisance du réglage.
• le « h » pour « hour »: mode C, correspondant au réglage de l'horaire de déclenchement 110'. C'est le mode qui suit le mode B après une autre pression sur le bouton poussoir 102. Dans ce mode, la couronne 103 permet d'effectuer un réglage d'une valeur d'horaire de déclenchement, avec, selon le mode de réalisation décrit, une précision au quart d'heure; le réglage est par ailleurs possible dans les deux sens, c'est à dire que la rotation de la couronne 103 dans un premier sens engendre la rotation de l'anneau portant les valeurs de déclenchement horaire 110" dans un premier sens, pas à pas grâce aux éléments d'indexation 111, et que la rotation de la couronne dans le sens inverse engendre la rotation de l'anneau dans le sens inverse. Cette fonctionnalité permet également d'augmenter considérablement l'aisance du réglage, dont la visualisation et facilitée par ailleurs grâce à l'affichage dissocié des paramètres de réglage, le guichet 110 et l'index 110"' montrant l'horaire de déclenchement étant situés à 6 heures, tandis que l'aiguille 109 pointant sur la valeur de quantième de déclenchement 109' est située à 9 heures. Le réglage séquentiel de chaque paramètre temporel avec le même organe de réglage, i.e. la couronne 103, est du reste particulièrement intuitif, comme sur une montre électronique.

We can visualize, on the figure 8A , the whole of the mode display disc 23 'on which are represented the four icons corresponding to each mode of operation, respectively:

• the barred bell: mode D, corresponding to the deactivated mode. This mode can be activated independently of the effective operation of the ringer, as explained above.
• the "d" for "day": mode B, corresponding to the setting of the trigger date 109 '. This is the mode which follows the mode D after a pressure on the push button 102, to which is connected the rod 1021, because the pawl 21 then drives the column wheel 22 in rotation in the counterclockwise direction, and therefore the wheel 23, to which the display disc 23 'is fixed, in the clockwise direction. In this mode, the ring 103 makes it possible to adjust the trigger date value 109 '; the adjustment is also possible in both directions, that is to say that the rotation of the ring 103 in a first direction causes the rotation of the needle 109 in a first direction, step by step through the elastic element of 33 'indexing, and that the rotation of the ring in the opposite direction causes the rotation of the needle 109 in the opposite direction. This feature greatly increases the ease of adjustment.
• the "h" for "hour": mode C, corresponding to the setting of the triggering time 110 '. This is the mode that follows the mode B after another press on the pushbutton 102. In this mode, the crown 103 makes it possible to adjust a trigger time value, with, according to the embodiment describes a quarter-hour precision; the adjustment is also possible in both directions, that is to say that the rotation of the ring 103 in a first direction causes the rotation of the ring bearing the time-release values 110 "in a first direction, step by step thanks to the indexing elements 111, and that the rotation of the ring in the opposite direction causes the rotation of the ring in the opposite direction.This feature also makes it possible to considerably increase the ease of adjustment, including visualization and facilitated Moreover, the dissociated display of the adjustment parameters, the window 110 and the index 110 "'showing the trigger time being located at 6 o'clock, while the needle 109 pointing to the trigger date value 109 is located at 9 o'clock. The sequential adjustment of each time parameter with the same adjustment member, ie the crown 103, is moreover particularly intuitive, as on an electronic watch.

• la cloche: correspondant au mode A d'enclenchement de l'alarme, activé par une pression sur le bouton poussoir 102 depuis le mode C précédent. Cette pression sur le bouton poussoir 102 est l'étape A1 d'enclenchement nécessaire à l'activation de l'alarme, qui libère le bras de dégagement du pont de dégagement 5. On pourra toutefois noter que, selon le mode de réalisation décrit même cette étape d'activation A1 n'est pas suffisante pour s'assurer que le dispositif d'alarme selon l'invention puisse générer une sonnerie ou tout autre type d'avertissement. Ceci ne pourra être réalisé que par un actionnement additionnel de la couronne 103 dans le sens de remontage du barillet 93; toutefois, cet actionnement aura pu être effectué au préalable et il n'est pas nécessaire, comme déjà expliqué précédemment, de se trouver dans le mode A pour pouvoir effectuer le remontage du barillet 93 de sonnerie, cette étape de remontage peut également être effectuée dans le mode D de désactivation. Dans un mode de réalisation alternatif selon lequel la sonnerie utilise le barillet du mouvement de base, une telle opération de remontage ne serait toutefois pas nécessaire mais simplement souhaitable pour ne pas entamer trop substantiellement la réserve de marche; dans ce cas la seule condition pour que le dispositif d'alarme puisse fonctionner serait que le mouvement horloger de base soit lui-même en fonction lors de l'enclenchement de l'alarme.

However, once this second adjustment has been made, the alarm device is still not activated and a separate additional step must be performed. A1 in order for the alarm to be activated, because in the mode C, the release arm is always located below the clearance bridge 5, preventing any vertical movement of the hourly release wheel 7 and thus the release of the hammer from 9. According to an alternative embodiment, one could imagine that this activation step A1 is not necessary and that the activation of the setting mode of the last parameter to be determined simultaneously engages the ringing device; However, this solution has the disadvantage of being able to trigger the alarm during adjustment, which makes it more difficult to use, insofar as it must be ensured that the adjustment step never coincides with the temporal parameters. trigger at the current time. The preferred solution comprising a separate engagement step A1 thus allows a better setting comfort.

• the bell: corresponding to the mode of activation of the alarm, activated by pressing the pushbutton 102 from the previous mode C. This pressure on the push button 102 is the activation step A1 necessary for the activation of the alarm, which releases the release arm of the release bridge 5. It may however be noted that, according to the embodiment described even this activation step A1 is not sufficient to ensure that the alarm device according to the invention can generate a ring or any other type of warning. This can only be achieved by an additional actuation of the ring gear 103 in the winding direction of the barrel 93; however, this actuation could have been done beforehand and it is not necessary, as already explained above, to be in mode A to be able to perform the winding of the barrel 93 ringer, this reassembly step can also be performed in D mode of deactivation. In an alternative embodiment in which the buzzer uses the barrel of the base movement, such a winding operation would not be necessary, but simply desirable not to too substantially reduce the power reserve; in this case the only condition for the alarm device to function is that the basic watch movement is itself in operation when the alarm is switched on.

The fact that the activation of all adjustment modes A, B, C, D is simultaneously displayed via the corresponding icon on the disk 23 'in the aperture 108 also improves the convenience of use. ; the adjustments are made sequentially, each time with the ring 103 after activation of a mode determining its function and the consequences of its rotation by pressing the push button 102. The activation of the alarm thus requires, depending on the mode of preferential embodiment described, three successive pressures of the push button 102, as well as the actuation of at least 3 times the adjusting ring 103, respectively for the winding of the barrel, before or after the adjustment steps, and the two stages of setting two distinct time parameters, here a trigger date value 109 'and a trigger time value 110'.

The Figures 9A, B are perspective views of the coupling gear between the timer of the basic movement and the hourly wheel 8, and the date correction wheel of the base movement of the dial and movement respectively. The Figures 9 C and D represent the same views as those of Figures A and B, respectively, but from above. These figures are intended to explain how the calendar deadline wheel 2 is synchronized with the date date displayed in the window 107 of the dial of the watch, visible on the figure 1 , and also how the deadline wheel 8 is also synchronized with the timer.

The Figures 9A and B highlight the push rod 104, located at two o'clock on the figure 1 , and which allows the setting of the date displayed in the aperture 107. The setting consists of incrementing in steps of one unit each time the pusher 104 is pressed. Fixed pivoting at the bottom of the rod of the pusher 104, there is a lever for adjustment of the date of the base movement 1041, which acts on a date adjustment ratchet of the base movement 1042. This pawl 1042 drives the toothing of the third calendar program tooth wheel of the base movement 16, which is incremented by a tooth. The indexing elements 14 ', 15', and 16 'have not been represented on the figures 9 A, B, C, D, but they allow the unit indexing of each of the elements 14,15 and 16 which it ensures the indexed positioning. The rotation of the wheel 16 drives that of the wheel 11 and teeth 13, which increments the unit values 107 ", and respectively tens 107 'displayed in the aperture 107 via the wheel 15 and the star 14. The indexing of the date units each day by the basic movement is effected by means of the indexing cam 1043 ', integral with the 24-hour wheel, meshing with the first wheel of the hours of the basic movement 1061, and which acts on the date adjustment ratchet of the base movement 1042. The indexing cam 1043 'allows the incrementation of a unit of the third date program gear of the base movement 16, and therefore, as explained in the previous paragraph, the incrementation of the value of the units 107 "displayed in the window 107. The indexing cam 1043 'is particularly visible on the Figures 9B and 9D .

The synchronization of the date-deadline wheel 2 with the calendar of the basic movement is simply ensured by the mutual gearing of the second gear wheel of the calendar program of the base movement 12 with the date-of-calendar wheel 2, as this is particularly visible on the Figure 9A . On the Figures 9B and 9D views from above the superposition of the date of maturity wheel 2 and the first trigger wheel 3 that they can not be distinguished; they are therefore referenced 2/3.

The basic movement comprises two wheels of distinct hours located in different planes: a first hour wheel 1061, and a second hour wheel 1061 ', much larger, engaged with the timer. The first hour wheel 1061 meshes with the 24 hour wheel 1043, which itself meshes with the transmission wheel 1062, in mesh with the hourly timing wheel 8. The transmission wheel 1062 thus serves as a reference and ensures the permanent synchronization of the hourly wheel 8 with the 24-hour wheel 1043, even when the hands 106 and 106 "are set for the hours and minutes of the basic movement through the ring 105.

The method for controlling and setting the alarm module described according to the invention makes it possible, thanks to the activation of the modes (A, B, C, D) with the aid of the push-button 102, and the setting of the parameters with the aid of the crown 103, a particularly effective handling of the clock watch, similar to that known for electromechanical watches which may include unique dedicated control and adjustment members. The solution therefore proposes an emulation of such an environment on a totally mechanical watch. However, the crown also allows an incremental and decremental adjustment of the time parameters used for the adjustment, here the date and the time, according to the direction of rotation. In this way, the use of such a mechanical member has the additional advantage of a faster adjustment because not limited to a single direction of adjustment to obtain the desired adjustment values.

Although the invention has been described in connection with an alarm module coupled to the basic movement, it will be understood that the described control devices and method using the combination of a pusher 102, a ring gear 103 and a column wheel 22 makes it possible to determine more modes of operation than the 4 modes A, B, C, D described and could be used to activate and respectively deactivate any type of gear powered by a cylinder, and perform different types of settings on it. train. One could also consider the pusher and the crown by other types of control and adjustment devices, provided that the convenience of use is not deteriorated; the crown and the pusher could for example be replaced by wheels arranged on the middle part of the watch.
