In the example illustrated by the figures, this third mechanism is a display mechanism capable of displaying the value of the first input quantity, or of the second input quantity, according to a selection made by the user.

More particularly, this first mechanism 100 and this second mechanism 200 operate continuously, independently of each other as to their operation, even if they can, for example, be powered by a single energy source.

According to the invention, this watch mechanism 1000 comprises a switching and clutch mechanism 500, which is arranged for the alternative and exclusive clutch between, on the one hand the first mechanism 100 or the second mechanism 200, which constitute two inputs operating more particularly each continuously, and on the other hand the third mechanism constituting an output.

This clockwork mechanism 1000 also comprises a control means 300, which can be operated by a user to disengage the one of the first mechanism 100 and second mechanism 200 which is engaged with the third mechanism, and to engage the other of the first mechanism 100 and second mechanism 200 with this third mechanism. The switching and clutch mechanism 500 comprises mechanical coupling means in a single angular position per revolution between on the one hand the first mechanism 100 or said second mechanism 200, and on the other hand said third mechanism, said means mechanical coupling authorizing clutching only in said unique angular position.

More particularly, this switching and clutch mechanism 500 comprises two input mobiles 1, 2, each constituted by an output mobile 101, 102, or driven directly by an output mobile 101, 102. This switching mechanism and clutch 500 comprises a sliding mobile 5, 935, 936, which is movable axially, and in particular on a clutch shaft 937, 938, in the first direction D1, and under permanent tension between the two input mobile parts 1, 2.

This portable mobile 5, 935, 936, is arranged to cooperate alternately and exclusively, by front latching in a single angular position per revolution, with one or the other of the two input mobiles 1, 2, selected under the action of a command printed by a user on the control means 300, to establish a drive connection between on the one hand the input mobile 1, 2, which is engaged with the portable mobile 5, 935, 936 , at the instant considered, and on the other hand this at least one third output mobile to rotate it by a stroke characteristic, as the case may be, of the first input quantity or the second input quantity.

More particularly, but not limited to, this third mechanism is a display mechanism for the respective display, on demand, on at least one display means, of a first or a second indications specific respectively to the first mechanism , and to the second mechanism. The clock mechanism 1000 then comprises such a switching and clutch mechanism 500 for producing a switchable display, the third output mobile is a display means 800, 8, 28.

Even more particularly, the output mobiles 101 and 102 are arranged to control the respective display, on at least one display means 800, 8, 28, on demand, of a first or a second indications specific respectively to the first mechanism, 100 and to the second mechanism 200.

By pure convention, the first mechanism 100 is called "upper", and the second mechanism 200 "lower", in particular the two clock movements, or the two cogs, or others, which are switched.

The invention is described for the particular and non-limiting case of switching a minute display, and for switching an hour display, these designations being used to distinguish the numerous components. Naturally the invention is also applicable to display switching for other horological quantities, or even to a switching mechanism for the transmission of an effort, a command, or other, the display being a particular case non-limiting.

More particularly, for the display of a first function, for example displaying the minutes and as visible on the figure 2 the portable mobile is a first portable mobile 5, 935 and the two input mobiles 1, 2 are coaxial around a first portable player axis D1. The first sliding mobile 5 is arranged to be engaged axially, directly or indirectly, with only one at a time of the two input mobiles 1, 2, by cooperation of complementary reliefs in a unique relative angular position per revolution for each mobile of entry 1, 2.

The first sliding mobile 5 comprises an external groove 59 allowing an external element such as a leaf spring 934, or a control lever, which the control means 300 comprises, to exert an axial, downward or upward force depending on the desired switching with an upper clutch wheel 3 or lower 4. The first sliding mobile 5 is held in its clutch position by at least one such leaf spring 934, or such a lever. More particularly, a leaf spring 934 is arranged to control the placing in axial position, then maintain the axial position of the first sliding mobile 5, 935. This means control 300 is also arranged to impart a rotational stroke to the first sliding mobile 5, 935, to search for the first clutch position between the first sliding mobile 5, 935, and the mobile towards which it is pushed. In the same way, the same leaf spring 934, or another leaf spring similarly controlled by the control means 300, can control the axial movement of another sliding mobile. THE figures 3 to 50 illustrate the preferred case where the same leaf spring 934 controls the simultaneous movements of a first sliding mobile 935 and a second sliding mobile 936.

More particularly, each portable mobile 5, 935, 936, is a coaxial clutch sliding sleeve. There figure 2 shows, for the management of the minute display, a first portable mobile 5, which is such a coaxial clutch slip sleeve for the clutch with on the one hand a lower minute clutch wheel 3 driven by friction by the first input mobile 1, in particular by means of elastic arms 13, and on the other hand an upper minute clutch wheel 4 driven by friction by the second input mobile 2, in particular by means of elastic arms 24. And the first input wheel 1, respectively the second input wheel 2, is arranged to drive the lower minute clutch wheel 3, respectively the upper minute clutch wheel 4.

This lower minute clutch wheel 3 and this upper minute clutch wheel 4 respectively comprise a first clutch element, not visible on the figure 2 , and a second clutch element 401, which are arranged to cooperate alternately in the clutch position, only one at a time, with a first complementary clutch element 5301 or with a second complementary clutch element, not visible on there figure 2 , which includes the mobile portable player concerned, here the first mobile portable player 5.

And the control means 300 is arranged to impart an axial stroke to this first sliding mobile 5 towards support on the lower minute clutch wheel 3 or respectively on the upper minute clutch wheel 4, and to print a stroke of rotation to the first sliding mobile 5, to search for the first clutch position between the first sliding mobile 5, and the lower minute clutch wheel 3, or respectively the upper minute clutch wheel 4, towards which it is pushed. In the case of figures 3 to 50 the first portable mobile 935 and the second portable mobile 936 are arranged in the same way, each sliding on its respective shaft 937, and 938.

We understand that the axial sliding movement of each sliding mobile on its respective shaft towards the clutch position is carried out in two stages: firstly the leaf spring exerts a force on the sliding mobile to put it in position axial support on the reliefs of one of the clutch wheels, then, during the relative rotation between this sliding mobile and this clutch wheel, these two mobiles reach the unique angular clutch position in which their male reliefs and respective females cooperate, to authorize the end of axial stroke corresponding to the clutch of the sliding mobile completely engaged in the clutch wheel concerned. When disengaging, axial support in the opposite direction exerted by the leaf spring authorizes the extraction and travel of the sliding mobile towards the other clutch wheel, and the sliding mobile travels an empty stroke between the extraction stroke of an upper clutch wheel and the support and introduction stroke towards the lower clutch wheel, or vice versa.

Different variants are described below for the arrangement of the first portable mobile 5, 935, they are applicable to the second mobile portable player 936, or any other similar portable mobile device that may include the switching and clutch mechanism 500.

More particularly, the switching and clutch mechanism 500 comprises at least one elastic return means which is arranged to axially push the first sliding mobile 5, 935, resting on the lower minute clutch wheel 3, or respectively the upper minute clutch wheel 4, towards which it is pushed.

More particularly, the first clutch element and the second clutch element are respectively a first clutch element and a second clutch element, which are arranged to cooperate alternately in the clutch position, only one at a time, with the first complementary clutch element or with the second complementary clutch element, which are respectively a first complementary clutch element and a second complementary clutch element.

More particularly, the control means 300 is arranged to impart a rotational stroke to an intermediate wheel secured in rotation to the first sliding mobile 5, 935, to seek a clutch position between the first sliding mobile 5, 935, and the wheel lower minute clutch wheel 3 or the upper minute clutch wheel 4, towards which it is pushed.

More particularly, the first sliding mobile 5, 935, comprises, on a first face facing the lower minute clutch wheel 3, and on a second face facing the upper minute clutch wheel 4, at least one tenon , or respectively a light, which is arranged or arranged to cooperate in a complementary manner with a light, respectively a tenon, which comprises the lower minute clutch wheel 3, and respectively the upper minute clutch wheel 4, on a unique position of cooperation during a relative rotation less than or equal to 360°, during the rotational stroke of the first portable mobile 5, 935.

More particularly, the first sliding mobile 5, 935, is mounted sliding on a first clutch shaft 937 with which it is indexed in rotation, which first clutch shaft 937 is arranged to drive in rotation, directly or indirectly, a means display 800, 8, 28.

More particularly, this first clutch shaft 937 is arranged to rotate a display means 800, 8, 28, through a cog incorporating the intermediate wheel, or through the intermediate wheel, which is indexed in rotation with the first clutch shaft 937.

More particularly, the first output mobile 101 and the second output mobile 102 are in permanent rotation.

The invention can be used for displaying all kinds of quantities.

More particularly, the first output mobile 101 and the second output mobile 102 are arranged to control the respective display, on at least one display means 800, 8, 28, of a first indication and a second indication , which are time indications.

A non-limiting example of application of the invention is described below for the display of two distinct time indications, on the same display support 800, in this case comprising a 28 hour hand and a minute hand 8.

More particularly, the first mechanism, in particular a first cog, 100 is driven by a first regulating member 1100, the second mechanism, in particular a second cog, 200 is driven by a second regulating member 1200, and this first regulating member 1100 and this second regulating member 1200 are arranged to operate in continuous, independently or not of each other, and without user intervention, for the respective display of a first and a second time indications, and respectively comprise a first input mobile 1 and a second mobile input 2 which are in permanent rotation.

More particularly, this first regulating member 1100 and this second regulating member 1200 are regulated differently. In a particular case, the first regulating member 1100 is adjusted for the display of a first time, and the second regulating member 1200 is adjusted for the display of a second time. The control means 300 allows the user to display the time at will according to the first time or according to the second time, and the mechanism according to the invention allows the continuation of the countdown of that of the two times which is not displayed at the moment in question.

There figure 2 thus shows the switching and clutch mechanism 500 for the example above: the first mechanism, in particular a first cog, 100, dedicated to the first time, called "lower", drives a first input mobile 1 which is a first lower minute wheel; the second mechanism, in particular a second cog, 200, dedicated to the second time, called "upper" drives a second input mobile 2 which is a second upper minute wheel. The first input wheel 1 is linked by friction to the lower minute clutch wheel 3, and the second input wheel 2 is linked by friction to an upper minute clutch wheel 4. The lower minute clutch wheel 3 and the upper minute clutch wheel 4 respectively comprise a first clutch element and a second clutch element, here constituted by projections extending in a direction parallel to that of the first axis of player D1, and distributed over different diameters, as visible on the Figure 35 ; the distal part of these projections is sloped or radiated, to facilitate cooperation with the lights included in the first portable mobile 5, 935. These lights, which are projected on a plane perpendicular to the axis D1 complementary to the salients, constitute the first complementary clutch element and the second element complementary clutch. Naturally these lights can be confused, on both sides of the first portable mobile 5, 935, to simplify manufacturing. The engagement cooperation between the lower minute clutch wheel 3, or respectively the upper minute clutch wheel 4, with the first sliding mobile 5, 935, is not possible, after the sliding mobile has been placed in support on the clutch wheel concerned, only in a single position per 360° revolution, as visible on the Figure 35 .

The axial support according to the direction of the first sliding axis D1 is easy to achieve: the first sliding mobile 5, 935, is movable on the first clutch shaft 937 according to a first square profile. In a variant, the first clutch shaft 937 carries an intermediate wheel which is thus integral in rotation with the first sliding mobile 5, 935. This intermediate wheel meshes with a minute track 8, pivoting around a display axis of the minutes. The first portable mobile 5, 935, thus ensures the coupling between this minute wheel 8 and the lower minute clutch wheel 3 or upper 4, corresponding to the minute wheel 1 or 2, depending on the time information to be displayed.

However, axial support alone is not enough, since it is necessary to find the angular position of concordance between the first sliding mobile 5, 935, and the lower minute clutch wheel 3 or upper 4 corresponding to the display to be carried out: it is only then possible to achieve clutching between the mechanisms concerned.

For this purpose, the control means 300 comprises means for driving the rotation of the first sliding mobile 5, 935, which are arranged to impose a rotation on it relative to the clutch wheel. lower minutes 3, or respectively to the upper minutes clutch wheel 4, towards which it is pushed axially, to search for the unique concordance position on a rotation less than or equal to 360°. The figures illustrate a non-limiting exemplary embodiment, which is distinguished by its small thickness, which is advantageous for allowing the accommodation of other complications in the timepiece 2000, in particular a watch.

The figures illustrate the extension of the principle explained above, to allow the display of several hourly quantities on the basis of the display of the minute by a minute switching group, and the display of the hours by a group switching hours. In a particular execution, the switching and clutch mechanism 500 is arranged to allow switching of the hour display, and comprises two secondary input mobiles. A second sliding mobile 936 is movable axially on a second clutch shaft 938 under permanent tension between these two secondary input mobile units.

More particularly, the second sliding mobile also includes a groove, and the two secondary input mobiles are coaxial around a second secondary sliding mobile axis. More particularly, the second sliding mobile is a coaxial clutch sliding sleeve, for clutching with on the one hand a lower hour clutch wheel driven by friction by the first secondary input mobile, and on the other hand an upper hour clutch wheel driven by friction by the second secondary input wheel, and the first secondary input wheel, respectively the second secondary input wheel, is arranged to drive the lower hour clutch wheel , respectively the upper hour clutch wheel. All the components of this assembly dedicated to switching the hour display are similar to those of the minutes.

The connection between the minute switching group and the hour switching group is possible by adding, on the minute switching group, intermediate transfer wheels, which are respectively secured to the lower minute clutch wheel 3 and the upper minute clutch wheel 4, and transition wheels, which respectively attack the lower hour clutch wheel and the upper hour clutch wheel. The second clutch shaft, which is the hour clutch shaft, carries a secondary intermediate wheel, held by a secondary screw, and which engages an hour road, in particular coaxial with the minute road. In the non-limiting embodiment, the leaf spring 934 is in the form of a Y-shaped fork, each of the branches of which acts on the first sliding mobile 5, 935, or the second corresponding sliding mobile 936.

This lower minute clutch wheel 3 and this upper minute clutch wheel 4 respectively comprise a first clutch element and a second clutch element, which are arranged to cooperate alternately in the clutch position, only one to both, with a first complementary clutch element or with a second complementary clutch element that the portable mobile includes.

And the control means 300 is arranged to impart an axial stroke to the first sliding mobile 5, 935, towards support on the lower minute clutch wheel 3 or respectively on the upper minute clutch wheel 4, and to print a rotational stroke at the first sliding mobile 5, 935, to search for the first clutch position between the first sliding mobile 5, 935, and the lower minute clutch wheel 3, or respectively the upper minute clutch wheel 4 , towards which he is pushed.

More particularly, the switching and clutch mechanism 500 comprises at least one elastic return means, which is arranged to axially push the first sliding mobile 5, 935, resting on the lower minute clutch wheel 3, or respectively the upper minute clutch wheel 4, towards which it is pushed.

THE figures 3 to 50 illustrate in detail a particular mode of execution of the invention, in no way limiting.

The switchable display mechanism 1000 concerns the display of the time indications of two separate cogs, and in particular but not limited to two separate clock movements. These two separate cogs are constantly working. In a particular variant, these cogs operate independently of each other, and include separate regulating organs. In another variant, the second mechanism, in particular a second cog, results from a multiplication of movements of certain mobiles of the first mechanism, in particular a first cog. The use of the switching mechanism makes it possible to display, at any time, one or other time information on demand.

• deux embrayages verticaux commutables (d'une part pour l'affichage de la minute et d'autre part pour l'affichage de l'heure dans le mode de réalisation particulier, non limitatif, illustré par les figures) ;
• un rouage qui peut provoquer un mouvement de rotation sur les deux arbres des accouplements verticaux ;
• un mécanisme qui contrôle le désengagement/ couplage et la transmission du mouvement de rotation.

The mechanism essentially consists of the following functional groups:

• two switchable vertical clutches (on the one hand for displaying the minute and on the other hand for displaying the time in the particular, non-limiting embodiment illustrated in the figures);
• a cog which can cause a rotational movement on the two shafts of the vertical couplings;
• a mechanism that controls disengagement/coupling and transmission of rotational motion.

THE figures 3 And 4 represent the complete mechanism, respectively on the dial side and the bridge side.

There Figure 5 represents a control mechanism 300, dial side, comprising, on the one hand a control lever 922 with toothed sectors operable by the user, and which controls the rotational movement and the clutches, and on the other hand a pivoting valve 930 intended to exert support on the leaf spring 934 comprising at least one connection fork 9345, 9346, arranged to cooperate with at least one sliding mobile at the level of a groove or the like, in particular and not limited to a first sliding mobile 935 and a second portable mobile 936, a succession of flip-flops: first flip-flop 923, second flip-flop 924, third flip-flop 925, fourth flip-flop 928, articulated to each other.

The third rocker 925 transmits the rotational movement to a pinion 926 carried by the fourth rocker 928.

The fourth rocker 928 comprises a pin 9280 which slides in a slot 9250 of the third rocker 925, and is subjected in its plane to the pressure of a rocker spring 929. The pinion 926 cooperates or not with a toothed sector 9259 of the before-fourth rocker 925 and/or with a single tooth 9270 which comprises a fixed plate 927 adjustable under the pressure of a rocker spring 929, to pivot the fourth rocker 928. The rocker spring 929 cooperates in support with a support support 931, adjustable during assembly. This fourth rocker 928 comprises a groove, respectively a finger, cooperating with a finger 9300, respectively a groove, of the pivoting valve 930, to pivot the pivoting valve 930 around an axis parallel to the plane to which all said rockers are parallel, and thus control the deformation and/or movement of the leaf spring 934.

The control lever 922 comprises, on either side of its median plane, two toothed sectors 9224 and 9221, each extended by a cylindrical bearing surface 9223, 9222, the two cylindrical bearing surfaces being located, in projection on this median plane, between the two toothed sectors, as visible on the figures 46 and 47 .

There Figure 6 , on the bridge side, shows the cooperation between the fourth rocker 928 and the pivoting valve 930. The Figure 7 shows the stacking of the rockers, and the rocker spring 929.

THE figures 8 to 10 illustrate a return mechanism in the rest position, comprising a return rocker 932, which is articulated to the control lever 922 which guides it, and, resting on a pin of this return rocker 932, a return spring 933, very voluminous, of dimensions similar to those of the largest rockers of the present mechanism, and which is very visible in the right part of the Figure 27 . This return spring 933 pushes the control lever 922 on the return rocker 932 in the final position, and constitutes a neutral spring, as will be explained later.

THE figures 11 to 13 illustrate the vertical clutch mechanism, which comprises the Y-shaped leaf spring 934, comprising forks 9345 and 9346 to move the first sliding mobile 935 and the second sliding mobile 936 on the respective clutch shafts of the minutes 937 and hours 938. A minute track 939 on the minute clutch shaft 937 is intended to receive a minute display, while the hour clutch shaft 938 includes a time wheel 940 for displaying the 'hour. Each portable mobile 935, 936 includes lights 9350, 9360, intended for coupling with the protuberances 930, 980, 950, 9100, which include the input clutch wheels 93, 98, 95, 910.

There Figure 14 shows the same vertical clutch mechanism, completed by different mobiles belonging to different sub-assemblies which are, from the bottom to the top of the figure: transfer cog of the lower movement, transfer cog of the upper movement, and transfer cog of display of hours, the latter finished by a roadway of hours 913, which is here and not limited to mounted coaxial to the roadway of 939 minutes. Figure 15 represents the same mechanism in section passing through the clutch shafts of minutes 937 and hours 938.

THE figures 16 to 18 illustrate the transfer train of the lower movement, which successively comprises a lower minute input wheel 91, comprising a friction for adjusting the display, a lower intermediate reversing wheel 92, a lower minute clutch wheel 93 , a lower reversing wheel 94, and a lower hour clutch wheel 95. The lower minute clutch wheel 93 and the lower hour clutch wheel 95 each comprise protrusions 930, 950, which are arranged to cooperate , in the clutch position, with these lights 9350, 9360, minute and hour clutch discs constituted by the mobile portable devices 935 and 936.

THE figures 19 to 21 illustrate the transfer train of the upper movement, which successively comprises an upper minute input wheel 96, comprising a friction for adjusting the display, an upper intermediate reversing wheel 97, an upper minute clutch wheel 98 , an upper reversing wheel 99, and an upper hour clutch wheel 910. The upper minute clutch wheel 98 and the upper hour clutch wheel 910 each comprise protrusions 980, 9100, which are arranged to cooperate with 9350, 9360 lights, minute and hour clutch plates.

THE figures 22 to 25 illustrate a rotation compensation mechanism comprising a first free-wheel mobile 914, free in the direction of clockwise, and a second free-wheel mobile 915 locking in the opposite direction to the first, connected by a first intermediate wheel 916 and by a second intermediate wheel 917.

THE figures 26 to 28 illustrate an hour rotation decoupling mechanism, comprising a third freewheel mobile 918, which decouples the movement of the switching in normal operation, meshing with a third hour friction mobile 919, which compensates for the rest of the rotational movement after the clutch.

THE figures 29 to 31 illustrate a minute rotation decoupling mechanism, comprising a fourth freewheel mobile 920, which decouples the movement of the switching in normal operation, meshing with a fourth minute friction mobile 921, which compensates for the rest of the rotational movement after the clutch.

THE figures 32 to 34 illustrate the hour display transfer gear visible in the upper part of the figures 14 and 15 , and which comprises a first hour transfer wheel 911, integral in rotation with the hour shaft 938, downstream of the hour rotation decoupling mechanism, and which meshes with an intermediate hour transfer wheel 912, with a integrated spring for taking up backlash, to drive an hour road 913 mounted coaxial with the minute road 939 on the minute axis.

There Figure 35 represents, in superposition, the unique position configuration by revolution of cooperation between the protuberances 930, 950, 980, 9100, of the minute and hour wheels on the one hand, and the lights 9350, 9360, of the clutch discs of the minutes and hours 935 and 936 on the other hand. The protrusions and lights are here distributed over three rays R1, R2, R3, of different values. Advantageously the angular positions are not equidistant, and the angles α12, α13 and a23 are different from each other.

THE figures 36 to 50 illustrate the main stages of the operation of switching the time information of the upper movement to that of the lower movement, with this second mode of execution of the invention.

THE figures 36 to 38 represent the control mechanism of figures 5 to 7 , in a switching start position; the leaf spring 934 is bent in its rest position, and without contact with the pivoting valve 930, the portable mobile devices 935 and 936 are in the high position.

THE figures 39 to 41 represent the same mechanism, in a minutes and hours disengagement position. The leaf spring 934 is pressed by the pivoting valve 930, the sliding mobiles 935 and 936 are in the middle position. An arrow shows, on the figure 39 , the movement of the third rocker 925, the pin 9280 which was at the end of its stroke in the light 9250 on the figures 3 And 36 , is now approximately in the middle of this light.

There figure 42 represents, similarly to the Figure 9 , the detail of the return mechanism in the rest position, with the passage of a neutral point PM when the return spring 933 ceases to oppose the switching, before accompanying this switching.

THE figures 43 to 45 represent the same control mechanism, in a minutes and hours disengaged position. The leaf spring 934 is pressed by the pivoting valve 930 in its lowest position, the sliding mobiles 935 and 936 are in the low position. On the figure 43 we see that the pin 9280 is now at the end of its travel in the light 9250 on the side opposite to that of the figures 3 And 36 .

THE figures 46 to 49 illustrate the cooperation between the control lever 922 and the first freewheel mobile 914, and the second freewheel mobile 915, visible on the figures 22 to 25 .

There figure 46 illustrates the cooperation between the first freewheel mobile 914, passing in the direction of clockwise, with a first lower cylindrical surface 9222 of the control lever 922, preventing it from rotating, and the cooperation between a second mobile with free wheel 915, running counterclockwise, with a second upper toothed sector 9224 of the control lever 922, authorizing its rotation.

We see on the figure 47 the control lever 922 with, at its lower part arranged to cooperate with the first freewheel mobile 914, a first cylindrical surface 9222 adjacent to a first toothed sector 9221, and, at its upper part arranged to cooperate with the second mobile to free wheel 915, a second cylindrical bearing surface 9223 adjacent to a second toothed sector 9224, these toothed sectors 9221 and 9224 extending on either side of the cylindrical bearing surfaces 9222 and 9223.

There figure 48 shows the lever and freewheels in the position of the figure 46 , when the control lever 922 begins to rotate clockwise. There figure 49 shows them during the continued rotation of the control lever 922 in the clockwise direction, during which the first freewheel mobile 914 leaves the first cylindrical bearing 9222 to mesh with the first toothed sector 9221, while the second mobile freewheel 915 leaves the second toothed sector 9224 to come to rest on the second cylindrical bearing 9223.

The time information corresponding to each of the two movements is stored in the clutch discs of the minute wheels, lower 93, or upper 98, or of the hour wheels, lower 95, or upper 910. The minute wheels / wheels of the hours, including the clutch plates, rotate constantly with the drives. The purpose of the switch is to access stored time information from only one of the two movements at a time.

We will first describe the switching of the time information of the upper movement to that of the lower movement.

Switching is carried out through a switching element on the housing, the user can switch between the two time information values.

The full stroke of the control lever 922 is divided into two stroke parts and supports the control of the leaf spring 934 (for declutching), as well as the transmission of rotary motion for position selection and re-clutching of the discs clutch of minutes 935 and hours 936.

In the first part of the stroke, the clutch discs 935 of the minutes and the hours 936 are disengaged, respectively from the upper minute clutch wheel 98, and from the upper hour wheel 910.

The second part of stroke allows the transfer of the rotational movement to the clutch shafts of minutes 937 and hours 938, therefore allowing the support, for probing, of the clutch discs of minutes 935 and hours 936, as well as that the clutch of these with the protuberances of the lower minute clutch wheel 93 and the lower hour wheel 95.

Let's detail the first part of the race:

• la lame-ressort 934 est ainsi déviée vers le bas par le clapet pivotant 930, ce qui réduit ainsi la pression avec laquelle les disques d'embrayage des minutes 935 et des heures 936 sont poussés vers le haut, respectivement sur la roue d'embrayage des minutes supérieure 98 et sur la roue d'heures supérieure 910, jusqu'à ce que les disques d'embrayage des minutes 935 et des heures 936 soient débrayés ;
• à partir de ce moment, les arbres d'embrayage des minutes 937 et des heures 938 sont libres en rotation, ainsi que les disques d'embrayage des minutes 935 et des heures 936 qui y sont associés, et ainsi que les aiguilles d'affichage ;

Clutch: in this case, the control lever 922 is tilted from bottom to top (in the top view), via a first rocker 923 and a second rocker 924 articulated on this first rocker 923, a third rocker 925 articulated on the second rocker 924 is pulled counterclockwise;

• if the third rocker 925 is now pulled counterclockwise by means of the pinion 926, the latter clings to the single tooth of the plate 927, and causes a rotational movement of the fourth rocker 928 in counterclockwise;
• the fourth rocker 928 includes another pin, which cooperates with a pivoting valve 930, to deflect it downwards, and thus press on the leaf spring 934; it is therefore this pivoting valve 930 which determines the position of the leaf spring 934, and which controls the switching;
• the leaf spring 934 is thus deflected downwards by the pivoting valve 930, which thus reduces the pressure with which the minute clutch plates 935 and hours 936 are pushed upwards, respectively on the clutch wheel upper minutes 98 and on the upper hour wheel 910, until the clutch discs of minutes 935 and hours 936 are disengaged;

Rotational movement: a rotational movement imparted to the control lever 922 is not yet transmitted to the first freewheel ball mobile 914 and the second freewheel ball mobile 915, which respectively allow clockwise rotations clockwise, and counterclockwise, and blocking in the opposite direction, and which are designed to mesh, in certain positions only, with one of the two toothed sectors 9221 and 9224 that the lever includes. control 922, each toothed sector being adjacent to a cylindrical surface 9222 or 9223 on which a wheel cannot mesh, but only slide.

• the first clockwise ball freewheel movable 914 is held in angular position via the surface of a cylindrical bearing 9222 of the control lever 922;
• the second freewheel ball mobile 915 in the counterclockwise direction is driven by the toothed sector 9224 of the control lever 922, by the lower teeth, and, since there is a rotational movement in the direction of the freewheel, this movement is not transferred to the upper teeth.

The state of the entire mechanism after the completion of the first part of the stroke is indicated on the figures 39 to 42 , relating to minute/hour decoupling. The end of the first part of the stroke is reached as soon as the toothed sector of the control lever 922 begins to mesh with the first freewheel ball mobile 914, and thus the transmission of the rotary movement is initiated.

Let's detail the second part of the race:

• la pression d'appui des disques d'embrayage des minutes 935 et des heures 936 est ainsi augmentée ;
• la plaque 927 comportant la dent unique est réglable de telle sorte que la pression maximale avec laquelle les disques d'embrayage des minutes 935 et des heures 936 sont pressés respectivement sur la roue des minutes inférieure 93 et sur la roue des heures inférieure 95 peut être réglée de manière optimale (si la pression est insuffisante, les disques d'embrayage ne sont pas appuyés sur les protubérances; si la pression est trop élevée, elle a pour effet de ralentir le mouvement, ce qui a donc un effet négatif sur l'amplitude) ;
• à partir d'un certain point, le pignon 926 est alors complètement au-dessus de la dent unique 9270, et roule et glisse lors d'une traction supplémentaire de la troisième bascule 925.

Clutch: the third rocker 925 is pulled further counterclockwise, and thus causes additional rolling of the pinion 926, and therefore also additional pivoting of the fourth rocker 928, which further pivots the pivot valve 930 , and thus exerts more pressure on the leaf spring 934;

• the support pressure of the clutch discs of minutes 935 and hours 936 is thus increased;
• the plate 927 having the single tooth is adjustable such that the maximum pressure with which the minute clutch plates 935 and hours 936 are pressed respectively on the lower minute wheel 93 and on the lower hour wheel 95 can be optimally adjusted (if the pressure is insufficient, the clutch discs are not pressed on the protrusions; if the pressure is too high, it has the effect of slowing down the movement, which therefore has a negative effect on the amplitude);
• from a certain point, the pinion 926 is then completely above the single tooth 9270, and rolls and slides during additional traction of the third rocker 925.

• après la deuxième roue intermédiaire 917, le mouvement de rotation est transformé au niveau d'un rouage pour les minutes d'une part, et d'un rouage pour les heures d'autre part ;
• cette division est nécessaire car les embrayages respectifs pour la minute et l'heure peuvent être couplés à des instants différents, selon la position relative des protubérances (sur la roue des minutes ou respectivement sur la roue des heures) par rapport à la position angulaire instantanée des disques d'embrayage des minutes 935 et des heures 936 ;
• les deux rouages nécessitent un troisième mobile à roue libre à billes 918, et respectivement un quatrième mobile à roue libre à billes 920, pour séparer le rouage et le mouvement, en ce qui concerne le mouvement de rotation, pendant le fonctionnement normal, si aucune commutation entre les affichages des deux mouvements n'est prévue ;
• en outre, chacun des deux rouages comporte une friction, respectivement une troisième roue à friction 921 des minutes et une quatrième roue à friction 919 des heures, chacune agencée pour glisser dès que l'accouplement est effectué entre le disque d'embrayage respectif et la deuxième roue supérieure des minutes 98 comportant les protubérances pour les minutes, respectivement la roue supérieure des heures 910 comportant les protubérances pour les heures, mais la course complète du levier de commande 922 n'est pas encore achevée ;

• les afficheurs, notamment mais non limitativement des aiguilles, tournent également au maximum à 360° (dans le sens des aiguilles d'une montre).

Rotational movement: the first freewheel ball mobile 914 is now (that is to say from the start of the second part of travel) driven by the toothed sector 9221 of the control lever 922;

• the rotational movement is transmitted by a first intermediate wheel 916 and by a second intermediate wheel 917;

• the upper wheel of the second ball freewheel 915 is driven by the second intermediate wheel 917; however, this does not cause blocking, because the upper wheel of the second ball freewheel 915 is driven in the direction of the freewheel;
• after the second intermediate wheel 917, the rotational movement is transformed at the level of a gear train for the minutes on the one hand, and a gear train for the hours on the other hand;

• the two cogs require a third freewheel ball mobile 918, and respectively a fourth freewheel ball mobile 920, to separate the cog and the movement, with regard to the rotational movement, during normal operation, if neither switching between the displays of the two movements is not provided;
• in addition, each of the two cogs comprises a friction, respectively a third friction wheel 921 for the minutes and a fourth friction wheel 919 for the hours, each arranged to slide as soon as the coupling is made between the respective clutch disc and the second upper minute wheel 98 comprising the protuberances for the minutes, respectively the upper hour wheel 910 comprising the protuberances for the hours, but the complete stroke of the control lever 922 is not yet completed;

• the minute 935 and hour 936 clutch discs are rotated to a maximum value of 360°, until the lights they contain come into correspondence with the protuberances of the lower minute wheel 93 or respectively of the lower hour wheel 95;

• dans la première moitié de l'angle de rotation du levier de commande 922, le ressort de rappel 933 contrecarre et contrarie le mouvement de rotation; dans la seconde moitié du mouvement de rotation le ressort de rappel 933 accompagne le mouvement de rotation, et pousse jusqu'au bout le levier de commande 922 dans sa position finale.

Rest position: the locking of the mechanism, and therefore the positioning at the start or respectively at the end of each switching by the user, is carried out via a return spring 933, which pushes the control lever 922 onto a control lever return 932, in the end positions, like a neutral leaf spring;

With regard to the reverse maneuver, relating to the switching of the time information of the movement lower than that of the higher movement, the processes are similar to those relating to switching from upper to lower movement, discussed above.

Only the direction of rotation of the control lever 922 and the associated movement of the control of the leaf spring 934 are reversed. The path of the control lever 922 is again divided into two stroke parts.

First part of the race:

Clutch: by the pressure of the leaf spring 934, the fourth rocker 928 is pushed against the pinion 926, clockwise, up to the single tooth of the plate 927;

• with continued movement of the control lever 922, the third rocker 925 is pivoted clockwise;
• the pinion 926 can now roll on the single tooth of the plate 927, and therefore on the fourth rocker 928 in a clockwise direction, which relaxes the leaf spring 934, which pushes the minute clutch discs 935 and hours 936 upwards until disengaging them from the upper minutes wheel 93, respectively from the upper hours wheel 95.

• le premier mobile à roue libre à billes 914 tourne dans le sens de la roue libre et ne transmet donc pas encore de mouvement de rotation.

Rotational movement: the second freewheel ball mobile 915 is held in position by the cylindrical bearing 9223 of the control lever 922;

• the first freewheel ball mobile 914 rotates in the direction of the freewheel and therefore does not yet transmit any rotational movement.

Second part of the race:

• le clapet pivotant 930 n'est plus en contact avec la lame-ressort 934 ;
• les disques d'embrayage des minutes 935 et des heures 936 sont appliqués et pressés sur la roue d'embrayage des minutes supérieure 98, ou respectivement la roue supérieure des heures 910.

Clutch: the 934 leaf spring is even more relaxed;

• the pivoting valve 930 is no longer in contact with the leaf spring 934;
• the minute clutch plates 935 and hours 936 are applied and pressed onto the upper minute clutch wheel 98, or respectively the upper hour wheel 910.

Rotational movement: the rotational movement of the control lever 922 is transmitted by its teeth, through the second ball freewheel mobile 915, to the cogs 916-917-918-919, or respectively 916-917-920-921 , towards the clutch shafts of the minutes 937 and the hours 938, to the clutch discs of the minutes 935 and the hours 936, for their engagement with the protuberances of the upper minute clutch wheel 98, or respectively of the upper hour wheel 910.

• le mécanisme d'entraînement en rotation, qui permet la saisie de la nouvelle information à afficher ;

Switching between a first and a second display indication on the same display medium, such as a conventional switch illustrated by the figure 1 , requires three phases: the disengagement of the first mechanism, in particular a first cog, corresponding to the first display indication, the search for synchronization of the second mechanism, in particular a second cog, corresponding to the second display indication, then the clutch of the second mechanism, in particular a second cog. These three phases are carried out thanks to the two functional mechanisms:

• the axial clutch, which allows the engagement and disengagement of each cog relative to the moving mobile;
• the rotation drive mechanism, which allows the entry of new information to be displayed;

And, when a user activates the control means to disengage the first mechanism 100 or said second mechanism 200 then engaged with the third mechanism, it moves, between two input mobiles connected respectively to the first mechanism 100 and to the second mechanism 200 and each comprising a frontal relief, a sliding mobile by a rocker and/or a control spring, to push it towards the input mobile corresponding to that of the first mechanism 100 and second mechanism 200 which was not engaged at the moment of the command, and we continue, as soon as they come into contact, the rotation of this input mobile until the cooperation of its frontal relief with a complementary frontal relief that includes said portable mobile, said frontal relief and said complementary frontal relief being such that their cooperation is achievable in a single angular position during a relative revolution between them, then their engagement is completed by axial thrust.

More particularly, this clock mechanism is a clock mechanism 1000 as described above, the mechanism of switching and clutch mechanism is the switching and clutch mechanism 500 as described above, and the control means is the control means 300 as described above.
