Definitions
- the present invention relates to a timepiece provided with a device for positioning a movable element in a plurality of discrete positions.
- the invention relates to a device for positioning a date ring in a plurality of display positions.
- the discs or rings used for displaying calendar data are held in any one of the plurality of display positions by a sautoir (also called spring-jumper).
- This jumper presses continuously against a toothing of the disc or of the ring in question.
- the toothing is configured so that the torque exerted on the jumper by its spring is minimal in the display positions and that, when driving the disc or the ring, the jumper passes through a torque peak. .
- the sizing of the calendar disks or rings, in particular the date rings, in the Watch movements is difficult because of the compromise to be found between guaranteeing the positioning function and minimizing the energy consumption of the system when switching from one display position to another.
- the spring cannot be too flexible because it is necessary to ensure the immobilization of the disc or the ring, but it cannot be excessively rigid because it would then generate a very important torque to be supplied by a clockwork movement mechanism.
- the mechanism for driving the disc or the ring can be bulky and there is a significant loss of energy for the energy source incorporated in the watch movement during the driving of this disc or of this ring.
- the document EP 2 998 799 describes a magnetic detent, in particular for a rotating bezel of a watch case.
- Two circular rows of magnets distributed regularly make it possible to define as many stable positions for the bezel as there are magnets per row (the magnets of the first row being oriented relative to the magnets of the second row to attract each other. ) and half as many stable positions in the case of magnets with alternating polarities along each circular row.
- the document EP 1 959 319 describes a magnetic device making it possible to drive a watch movement in rotation in its case by an external magnetic ring. Such a magnetic actuation is provided for setting the time of the watch without a conventional stem-crown which passes through the watch case.
- the document US 4,409,576 describes an electrical switch having two stable switching positions along a linear axis in the direction of which the magnetic axes of two magnets forming this electrical switch are aligned.
- the first magnet is applied against a ferromagnetic part to which it adheres at least magnetically.
- the ferromagnetic part is arranged between the two magnets.
- the second magnet is integral in translation with a shuttle that can be actuated manually between the two switching positions.
- the magnetic system formed by the two magnets and the ferromagnetic part makes it possible to maintain the shuttle stably in the two switching positions, thus defining a bistable system.
- the objective of the present invention is to solve the problems associated with conventional jumpers and to propose a device for positioning a mobile element, capable of successively occupying a plurality of discrete stable positions, which is safe, relatively compact and which requires relatively little energy for the watch movement to move from one discreet stable position to another.
- the present invention relates to a watch movement comprising a mobile element, which is capable of being driven along a displacement axis and of being momentarily immobilized along this displacement axis successively in a plurality of discrete stable positions, and a device for positioning this movable element in any one of the plurality of discrete stable positions.
- the positioning device comprises a rocker and a magnetic system formed of a first magnet, a second magnet secured to the rocker and a magnetic structure secured to the movable element, this magnetic structure being made of a material to high magnetic permeability and exhibiting, relative to the axis of movement, a transverse dimension which varies periodically so as to define a plurality of periods which correspond, for the mobile element, respectively to the distances to be traveled between the positions of the plurality of discrete stable positions.
- the first and second magnets are arranged so that their magnetic axes have opposite directions, in projection on a reference axis passing substantially through the respective centers of these first and second magnets, and respectively on one side and the other of the magnetic structure so that when the movable member is driven along its axis of movement from any stable position to a next stable position, the magnetic structure passes between the first and second magnets.
- the magnetic system is further arranged so that, when the movable member is driven along its axis of movement from any stable position to a next stable position, a first magnetic torque exerted on the rocker carrying the second magnet presents a first direction on a first section and a second direction, opposite to the first direction, on a second section of the corresponding distance, the first direction corresponding to a return torque in the direction of the movable element for a contact part of said rocker , while the second direction tends to separate this contact part of the movable element.
- the magnetic structure is arranged along the axis of movement so that, for each position of the plurality of discrete stable positions, the first magnetic torque is applied in the aforementioned first direction.
- the magnetic system generates a second magnetic torque which is exerted directly on the magnetic structure and thus on the mobile element.
- this second magnetic torque has a zero value, corresponding to a stable magnetic equilibrium position for the mobile element, while the first magnetic torque is applied to the rocker in the first direction.
- the latch is associated with a spring which exerts an elastic force on this latch so as to generate a mechanical torque which pushes the contact part of this latch in the direction of a toothing that the mobile element has and in which this contact part penetrates to mechanically position the movable element.
- the mobile element forms a display medium for calendar data.
- the mobile element is a date ring.
- the magnetic system 2 comprises a first fixed magnet 4, an element with high magnetic permeability 6 and a second magnet 8 which is movable, along a displacement axis coinciding here with the alignment axis 10 of these three magnetic elements, relative to the assembly formed by the first magnet 4 and the element 6.
- the element 6 is arranged between the first magnet and the second magnet, close to the first magnet and in a determined position relative to the latter.
- the distance between element 6 and magnet 4 is less than or substantially equal to one tenth of the length of this magnet along its magnetization axis.
- Element 6 consists, for example, of a carbon steel, tungsten carbide, nickel, FeSi or FeNi, or other alloys with cobalt such as Vacozet® (CoFeNi) or Vacoflux® (CoFe).
- this element with high magnetic permeability consists of a metallic glass based on iron or cobalt.
- Element 6 is characterized by a field of saturation Bs and a permeability ⁇ .
- the magnets 4 and 8 are for example made of ferrite, FeCo or PtCo, rare earths such as NdFeB or SmCo. These magnets are characterized by their remanent field Br1 and Br2.
- the high magnetic permeability element 6 has a central axis which is preferably substantially coincident with the magnetization axis of the first magnet 4 and also with the magnetization axis of the second magnet 8, this central axis being here coincident with the alignment axis 10.
- the respective magnetization directions of the magnets 4 and 8 are opposite. These first and second magnets therefore have opposite polarities and they are capable of undergoing relative movement between them over a certain relative distance.
- the distance D between the element 6 and the mobile magnet 8 indicates the distance of this mobile magnet relative to the assembly formed of the other two elements of the magnetic system.
- the axis 10 is provided here linear, but this is a non-limiting variant.
- the displacement axis can also be curved, as in the embodiments which will be described below.
- the central axis of the element 6 is preferably approximately tangent to the curved axis of displacement of the mobile magnet and thus the behavior of such a magnetic system is, in a first approximation, similar to that of the magnetic system described here. This is all the more true as the radius of curvature is large relative to the maximum possible distance between the element 6 and the mobile magnet 8.
- the element 6 has dimensions in a plane orthogonal to the central axis 10 which are greater than those of the first magnet 4 and those of the second magnet 8 in projection in this orthogonal plane. It will be noted that, in the case where the second mobile magnet abuts at the end of its travel against the element with high magnetic permeability, this second magnet advantageously comprises a hardened surface or a thin layer of hard material on its surface.
- the two magnets 4 and 8 are arranged in magnetic repulsion so that, in the absence of the high magnetic permeability element 6, a magnetic repulsion force tends to move these two magnets away from each other.
- the arrangement between these two magnets of the element 6 reverses the direction of the magnetic force exerted on the mobile magnet when the distance between this mobile magnet and the element 6 is sufficiently small, so that the moving magnet then undergoes a force of magnetic attraction.
- Curve 12 of the Figure 2 represents the magnetic force exerted on the mobile magnet 8 by the magnetic system 2 as a function of the distance D between the mobile magnet and the element with high magnetic permeability.
- the mobile magnet undergoes, over a first range D1 of the distance D, overall a magnetic force of attraction which tends to maintain the mobile magnet against the element 6 or to bring it back towards it in the event of 'distance, this overall force of attraction resulting from the presence of the element with high magnetic permeability (in particular ferromagnetic) between the two magnets, which allows a reversal of the magnetic force between two magnets arranged in magnetic repulsion, while this mobile magnet undergoes, on a second range D2 of the distance D, overall a magnetic repulsion force.
- This second range corresponds to distances between element 6 and magnet 8 which are greater than the distances corresponding to the first range of distance D.
- the second range is practically limited to a maximum distance D max which is generally defined by a stop limiting the distance of the moving magnet.
- the magnetic force exerted on the mobile magnet is a continuous function of the distance D and it therefore has a zero value at the distance D inv for which there is an inversion of this magnetic force ( Figure 2 ).
- the inversion distance D inv is determined by the geometry of the three magnetic parts forming the magnetic system and by their magnetic properties. This inversion distance can therefore be selected, to a certain extent, by the physical parameters of the three magnetic elements of the magnetic system 2 and by the distance separating the fixed magnet from the element. ferromagnetic 6.
- the watch movement 20 comprises a date ring 22, which is capable of being driven in clockwise rotation, along a circular displacement axis 24, and of being momentarily immobilized along this displacement axis successively in a plurality discrete stable positions.
- the watch movement comprises a device for positioning the date ring in any one of the angular positions of the plurality of discrete stable positions, this positioning device being formed of two complementary systems which are associated, namely a mechanical system, formed by a rocker 30 associated with a spring 32 and by a toothing 26 comprising a plurality of hollows or notches 28 in which is successively inserted an end part 31 of the rocker (which defines a contact part with the toothing) when the ring is successively positioned in the angular positions of said plurality of discrete stable positions, and a magnetic system formed of a first fixed magnet 34, a second magnet 36 integral with the rocker and a magnetic structure 38 integral ring 22.
- the magnetic structure 38 is made of a material with high magnetic permeability and has, relative to the axis of movement of the ring 22, a transverse dimension which varies periodically by defining a plurality of angular periods ⁇ P which correspond, for l 'movable ring, at the angular distances that it must travel between its display positions (plurality of discrete stable positions). More particularly, in the variant described in Figures 3 and 4 , the dimension transverse of the magnetic structure varies periodically between a maximum distance L1 and a minimum distance L2.
- This magnetic structure forms a crown with inner protrusions 40 (magnetic teeth) and outer protrusions 44 which are radially aligned with the protrusions 40.
- each pair of protrusions 40 and 44 arranged on the same radius of the ring defines the maximum width L1 of the magnetic structure while intermediate parts 42 define the minimum width L2.
- the pairs of protrusions are radially aligned with the notches 28 of the toothing 26.
- Each pair of protrusions and the respective notch define a radial axis corresponding to a stable display position P n (n being a natural number) of l ring 22.
- Each angular period ⁇ P lies between two successive maximum widths L1.
- the teeth can be formed by the internal profile of the magnetic structure.
- the first magnet 34 and the second magnet 36 are arranged respectively on one side and the other of the magnetic structure 38 with their magnetic axes substantially aligned with an AREF reference axis that they define (this axis passing substantially through their centers respective).
- the magnetic axes of the two magnets have opposite directions (magnets with their opposite polarities). Then, these first and second magnets, and therefore the flip-flop 30, are arranged so that, when the date ring is driven along its axis of movement 24, the magnetic structure passes between these two magnets.
- the magnetic couple described above forms a first magnetic positioning couple of the ring 22 by means of the latch fixedly bearing the magnet 36, this latch also forming a mechanical positioning system of the ring. dates.
- the magnetic system of the positioning device of the invention also generates a second magnetic torque on the ring 22 thanks to a magnetic force exerted by the magnetic system directly on the magnetic structure 38, this second magnetic torque reinforces the first magnetic torque since the magnetic structure (the magnetic teeth) is arranged so that the second magnetic torque is relatively low, preferably almost zero, when the ring is in any of its angular display positions, and that it increases relatively quickly on either side of each position display so as to oppose initially a displacement of the ring out of the display position which it occupies, by recalling the ring towards this display position.
- the evolution of the second magnetic torque is shown at Figure 6 .
- this second magnetic couple has a conservative character, that is to say that the energy necessary, during the drive of the ring over a first half-period, to overcome the return torque exerted on the magnetic structure is substantially returned to the ring over the second half-period since the second magnetic couple then has the same direction (positive direction) as the drive torque over this second half-period.
- the remanent field of each of the two magnets is equal to 1.35 T and the saturation field of the magnetic structure in ferromagnetic material (Vacoflux®) is equal to 2.2 T.
- a first curve 50 giving the magnetic torque exerted on the rocker when the latter is in an open position (corresponding to a position for which the end part 31 is located outside the toothing 26) and that the ring is driven over an angular period ⁇ P between two successive display positions (that is to say from any display position to a following display position); - a second curve 52 giving the magnetic torque exerted on the rocker when the latter is in a closed position (corresponding to a position for which the end part 31 is located at the bottom of the toothing 26, that is to say in a notch 28); and a third curve 54 representing approximately the functional magnetic torque applied to the latch over each angular period, this functional magnetic torque defining the first magnetic torque.
- the curve 52 is theoretical since the rocker does not cannot be maintained in a closed position during an angular displacement of the ring over a distance corresponding to an angular period in the presence of the ring with its toothing 26.
- a curve can be observed by taking a ring of test having a profile in its general plane corresponding to that of the magnetic structure.
- the curve 54 of the functional torque is an approximation of the real behavior since the position of the rocker does not depend only on the first magnetic couple but also on the profile of the toothing 26, on the profile of the end part 31 of this rocker and on the torque.
- mechanical generated by the spring in the first embodiment (It will be noted that the functional torque shown corresponds in fact to an embodiment without a spring and without toothing).
- the notches have a profile designed to mechanically position the ring with a small clearance and maintain it correctly in the display positions.
- the curve 54 only meets the curve 52 in the angular zones close to the stable display positions P n .
- the functional magnetic torque corresponds substantially to that of the curve 52 for each of the display positions P n .
- the first direction corresponds to a return torque in the direction of the movable ring for the contact part of the rocker, while the second direction tends to move this contact part away from the ring and in particular from its teeth 26.
- the magnetic structure 38 is arranged along the axis of movement 24 of so that, for each position P n of the plurality of discrete stable positions (display positions), the first magnetic torque is exerted in the aforementioned first direction.
- the end portion 31 of the rocker 30 bears against the teeth 26 of the ring 22 at least when the first magnetic torque is applied to this rocker in the first direction.
- the toothing and the rocker are arranged so that the end part 31 is located at the bottom of this toothing for each discrete display position P n .
- the first magnetic torque is applied in the first direction to continuous sections each formed of a first part TR1a and a second part TR1b located respectively on both sides of a stable position P n .
- the first magnetic couple (functional couple 54) has a maximum negative value (that is to say maximum in absolute value) for an angular position P CM close to each discrete stable position P n . In an advantageous variant, this maximum negative value is reached substantially at each discrete stable position P n .
- the end part 31 of the lever which presses against the teeth here comprises the second magnet 36.
- the non-magnetic support forming this end part and carrying the second magnet to be in abutment. against the toothing 26 so that this second magnet can approach the magnetic teeth 40 without, however, coming into contact with the ring.
- the second magnet has a contact surface with the toothing, this contact surface being hardened by an appropriate treatment.
- the part of the second magnet located on the side of the toothing is protected by a protective layer deposited on the second magnet, this protective layer being in contact with the toothing.
- a first curve 56 giving the magnetic torque applied to the magnetic structure, and therefore directly to the ring when the latch is in an open position and the ring is driven over an angular period ⁇ P ; a second curve 58 giving the magnetic torque applied to the magnetic structure when the latch is in a closed position; and a third curve 60 representing approximately the functional magnetic torque applied to the magnetic structure over each angular period, this functional magnetic torque defining a second magnetic torque intervening in the positioning device of the invention.
- the second magnetic torque has a substantially zero value at the position P n defining the start of an angular period between two display positions.
- the magnetic structure and therefore the ring 22 are in a stable magnetic position because the negative slope of the curve 60 at this position P n indicates that the second magnetic couple tends to bring the ring back to this position when it moves away from it (positive direction of the angle of rotation is clockwise).
- the ring and the latch are arranged so that each position P n of the plurality of discrete stable positions corresponds to a stable magnetic position, as is the case in the first embodiment.
- the first magnetic torque is applied to the rocker in the first direction when the ring is in a any stable magnetic equilibrium position.
- the maximum negative value of the first magnetic torque is reached for angular positions close to the positions of stable magnetic equilibrium.
- the first magnetic torque exerted on the rocker has a value close to the maximum value of this first magnetic torque in the first section where the first magnetic torque is exerted in the first meaning.
- the latch and the magnetic system are arranged so that said maximum value is substantially reached for each stable magnetic position, which corresponds to a display position of the date ring.
- the second magnetic torque 60 has in each angular period a negative value on a first section TR3 and a positive value on a second section TR4. Each of these two sections extends substantially over a half-period. It will be noted that this second magnetic couple has a zero value between these two sections, this position corresponding to an unstable magnetic equilibrium position. In this position, the AREF reference axis passes substantially between two magnetic teeth 40 and therefore between two notches or recesses 28 of the toothing 26, these notches or recesses being aligned radially with the magnetic teeth 40.
- the spring 32 pressing on the lever generates a mechanical torque applied by the lever to the ring 22.
- this mechanical torque can be relatively low given the first and second magnetic couples generated by the magnetic system which are exerted on the latch. 'ring in the same direction as this mechanical couple when the ring is in any one of the plurality of display positions.
- the mechanical torque can be greater than the first magnetic torque applied in the second direction, that is to say its value. maximum positive on the second section TR2, so that the part 31 of the lever remains continuously in abutment against the teeth 26 of this lever.
- the mechanical torque is less than this maximum positive value over a certain angular pivoting distance of the rocker.
- the rigidity of the spring is advantageously selected so that this spring limits, in the second section TR2, the distance of the magnet 36, carried by the end part 31 of the lever, relative to the magnetic structure 38. If this is not the case, then an element of the watch movement must have a stop function for the rocker when the part 31 moves away from the toothing, so as to limit its distance from this toothing in the second section TR2 of each period.
- the two magnetic forces which are exerted respectively on the rocker via the magnet which it carries and on the ring via the magnetic structure which it carries or of which it is formed, are vectors which each have a certain variable intensity and also a variable direction in the general plane of the ring and the rocker. These two parameters (intensity and direction) intervene in the first magnetic couple and in the second magnetic couple.
- the first magnetic couple is defined relative to the pivot axis of the rocker while the second magnetic couple is defined relative to the geometric axis of rotation of the ring.
- the Figure 7A corresponds to a display position of the ring where the force vector 64a is oriented radially, which corresponds to a zero value of the second magnetic torque and to a stable equilibrium position.
- the first magnetic torque is substantially maximum in the positive direction (direction in which the free end of the lever presses against the ring). This first magnetic torque is added here to the mechanical torque exerted by a spring (not shown) on the lever.
- a situation is observed in which the first magnetic torque is always positive (clockwise), but greatly reduced, and the second magnetic torque is negative (counterclockwise).
- the second magnetic couple here opposes the angular displacement of the ring clockwise (direction of drive).
- the first magnetic torque has become negative and the second magnetic torque remains negative.
- the force vector 62d has a direction substantially opposite to the force vector 62a of the Figure 7A , these two vectors being approximately oriented radially. There is therefore a reversal of the magnetic force exerted on the mobile magnet 36 during a drive of the ring from a given position to the Figure 7A up to a given position at the Figure 7D .
- the force vector 64d has become positive at this Figure 7D , the ring thus also being driven by the second magnetic couple in its angular displacement.
- the first magnetic couple became positive again before the next display position is reached, the rocker thus pressing again against the ring, while the second magnetic couple still drives the ring towards the next display position.
- FIG 8 To the Figure 8 is shown an alternative embodiment which differs from that of Figures 3 and 4 in that the magnetic structure 38A integral with the date ring 22A has a circular profile on the side of the fixed outer magnet 34.
- the distance between the magnetic structure and the The external magnet is constant.
- the variation in width of the magnetic structure is therefore obtained here only by the internal magnetic teeth formed by the teeth. 40 of this structure.
- the behavior of the magnetic system of this watch movement 70 is essentially similar to that of the variant described above.
- FIG. 9 A second embodiment of the invention is shown in Figure 9 .
- the references already described and the operation of the magnetic system will not be described again here in detail. It will be noted that this operation is essentially similar to that of the first embodiment.
- the second embodiment of a watch movement 80 according to the invention differs from the first embodiment by the shape of the magnetic structure. While in the first mode, the magnetic structure extends continuously along the movable element along its axis of movement, the magnetic structure 84, carried by the date ring 82, is formed of a plurality of elements. separate magnetic 86. These magnetic elements are radially aligned respectively with the plurality of notches 28 of the toothing 26 of the ring 82.
- the magnetic structure 84 is therefore formed of a plurality of distinct magnetic elements 86 made of a material with high magnetic permeability, in particular of a ferromagnetic material. These magnetic elements 86 are arranged along the ring along the axis of movement 24 with a space without material of high magnetic permeability between any two distinct successive elements.
- the first and second magnetic pairs act constructively with the mechanical torque generated by the spring 32 to position the ring in any position of the plurality of display positions and to maintain it in this position. position in the absence of a drive of the ring by its drive mechanism arranged in the watch movement (mechanism known to those skilled in the art).
- the drive mechanism must therefore defeating the first and second magnetic couples as well as the mechanical torque to drive the ring from one stable display position to a next stable display position.
- the second magnetic torque is substantially conservative.
- the first magnetic couple as well as the mechanical couple can restore some energy to the ring in the second half of the displacement between two stable display positions. This also depends on the profile of the teeth and of course on the frictional force of the lever on the teeth of the ring.
- the positioning device according to the invention is remarkable in that the first magnetic couple which is exerted on the rocker decreases rapidly as soon as the end portion 31 of the rocker begins to exit from one of the notches 28 and then changes sign as the ring is driven further to move from one display position to another.
- the magnetic torque decreases as soon as the lever is moved away from the ring via its toothing, which therefore rapidly decreases the magnetic positioning torque as soon as one moves away from a stable position. discreet.
- the rocker moves away from the toothing, the first magnetic torque decreases sharply and even reverses, so that the passage of a tooth is greatly facilitated and thus requires little energy.
- the magnetic elements 86 have an oblong shape with the two tapered ends. In a variant, these magnetic elements simply have a rectangular shape.
- the magnetic system is arranged so that the magnet carried by the rocker undergoes an attractive force in the direction of the teeth of the ring when a magnetic element is inserted between this mobile magnet 36 and the fixed magnet 34
- the magnet 36 is subjected to a repulsive force oriented substantially in the direction of the center of rotation of the ring.
- FIG. 10 a third embodiment of a watch movement 90 according to the invention is shown at Figure 10 .
- This third mode differs from the two preceding modes by the fact that no mechanical torque is generated by the positioning device.
- no spring is associated here with the lever 30.
- a stop 92 is provided to limit the rotation of the lever in the clockwise direction (positive direction in the present description) when the first magnetic torque becomes positive and for prevent the rocker from being in an angular position where the magnetic torque which is exerted on it in the open position no longer allows a return in the direction of the teeth 26 when the end part 31 is again presented opposite a notch 28 of the teeth. Indeed, it is necessary that the magnetic system alone can bring the lever against the teeth.
- the first magnetic couple remains negative around the discrete stable positions P n when the latch goes from a closed position to an open position. This is important for this third embodiment.
- the magnetic torque which is applied to it allows it to be driven into this notch and therefore towards its closed position.
- the dimensioning of the elements of the magnetic system and their spatial arrangement as well as the arrangement of the rocker, in particular its pivot axis, are provided so that the magnetic torque in the open position of the rocker is sufficient to drive its end part at the bottom of the teeth from the open position, namely here at the bottom of a notch when the latter is presented opposite the end part.
- the dimensioning of the magnets and their magnetic characteristics make it possible in particular to adjust the first magnetic couple.

Description
La présente invention concerne une pièce d'horlogerie munie d'un dispositif de positionnement d'un élément mobile dans une pluralité de positions discrètes. En particulier, l'invention concerne un dispositif de positionnement d'un anneau des quantièmes dans une pluralité de positions d'affichage.The present invention relates to a timepiece provided with a device for positioning a movable element in a plurality of discrete positions. In particular, the invention relates to a device for positioning a date ring in a plurality of display positions.
De manière classique, les disques ou anneaux servant à l'affichage d'une donnée de calendrier (quantième, jour de la semaine, mois, etc.) sont maintenus dans l'une quelconque position de la pluralité de positions d'affichage par un sautoir (aussi nommé ressort-sautoir). Ce sautoir presse continument contre une denture du disque ou de l'anneau en question. Lors du passage d'une position d'affichage à une autre, le sautoir s'écarte de la denture en subissant un mouvement de rotation dans un sens opposé à la force de rappel exercée par le ressort du sautoir. Ainsi, la denture est configurée de sorte que le couple exercé sur le sautoir par son ressort soit minimal dans les positions d'affichage et que, lors de l'entraînement du disque ou de l'anneau, le sautoir passe par un pic de couple. Si on veut assurer le positionnement en cas de choc, il faut dimensionner la denture et le sautoir, en particulier la rigidité du ressort, de manière que le pic de couple susmentionné (couple maximal à vaincre pour changer l'affichage) soit relativement important. Ainsi, le dimensionnement des disques ou anneaux de calendrier, en particulier des anneaux des quantièmes, dans les mouvements horlogers est difficile à cause du compromis à trouver entre garantir la fonction de positionnement et minimiser la consommation énergétique du système lors du passage d'une position d'affichage à une autre. En effet, le ressort ne peut pas être trop flexible parce qu'il faut assurer l'immobilisation du disque ou de l'anneau, mais il ne peut pas être excessivement rigide parce qu'il engendrerait alors un couple très important à fournir par un mécanisme du mouvement horloger. Dans ce dernier cas, le mécanisme d'entrainement du disque ou de l'anneau peut être encombrant et on a une perte d'énergie importante pour la source d'énergie incorporée dans le mouvement horloger lors de l'entraînement de ce disque ou de cet anneau.Conventionally, the discs or rings used for displaying calendar data (date, day of the week, month, etc.) are held in any one of the plurality of display positions by a sautoir (also called spring-jumper). This jumper presses continuously against a toothing of the disc or of the ring in question. When changing from one display position to another, the jumper moves away from the teeth by undergoing a rotational movement in a direction opposite to the return force exerted by the spring of the jumper. Thus, the toothing is configured so that the torque exerted on the jumper by its spring is minimal in the display positions and that, when driving the disc or the ring, the jumper passes through a torque peak. . If we want to ensure the positioning in the event of an impact, it is necessary to size the teeth and the jumper, in particular the stiffness of the spring, so that the aforementioned peak of torque (maximum torque to be overcome to change the display) is relatively high. Thus, the sizing of the calendar disks or rings, in particular the date rings, in the Watch movements is difficult because of the compromise to be found between guaranteeing the positioning function and minimizing the energy consumption of the system when switching from one display position to another. Indeed, the spring cannot be too flexible because it is necessary to ensure the immobilization of the disc or the ring, but it cannot be excessively rigid because it would then generate a very important torque to be supplied by a clockwork movement mechanism. In the latter case, the mechanism for driving the disc or the ring can be bulky and there is a significant loss of energy for the energy source incorporated in the watch movement during the driving of this disc or of this ring.

La présente invention a pour objectif de résoudre les problèmes liés aux sautoirs classiques et de proposer un dispositif de positionnement d'un élément mobile, susceptible d'occuper successivement une pluralité de positions stables discrètes, qui soit sûr, relativement peu encombrant et qui demande relativement peu d'énergie au mouvement horloger pour passer d'une position stable discrète à une autre.The objective of the present invention is to solve the problems associated with conventional jumpers and to propose a device for positioning a mobile element, capable of successively occupying a plurality of discrete stable positions, which is safe, relatively compact and which requires relatively little energy for the watch movement to move from one discreet stable position to another.
A cet effet, la présente invention concerne un mouvement horloger comprenant un élément mobile, lequel est susceptible d'être entraîné selon un axe de déplacement et d'être immobilisé momentanément le long de cet axe de déplacement successivement dans une pluralité de positions stables discrètes, et un dispositif de positionnement de cet élément mobile dans une quelconque des positions de la pluralité de positions stables discrètes. Le dispositif de positionnement comprend une bascule et un système magnétique formé d'un premier aimant, d'un deuxième aimant solidaire de la bascule et d'une structure magnétique solidaire de l'élément mobile, cette structure magnétique étant constituée d'un matériau à haute perméabilité magnétique et présentant, relativement à l'axe de déplacement, une dimension transversale qui varie périodiquement de manière à définir une pluralité de périodes qui correspondent, pour l'élément mobile, respectivement aux distances à parcourir entre les positions de la pluralité de positions stables discrètes. Les premier et deuxième aimants sont agencés de manière que leurs axes magnétiques ont des sens opposés, en projection sur un axe de référence passant sensiblement par les centres respectifs de ces premier et deuxième aimants, et respectivement d'un côté et de l'autre de la structure magnétique pour que, lorsque l'élément mobile est entraîné le long de son axe de déplacement d'une quelconque position stable à une position stable suivante, la structure magnétique passe entre les premier et deuxième aimants. Le système magnétique est en outre agencé de manière que, lorsque l'élément mobile est entraîné le long de son axe de déplacement d'une quelconque position stable à une position stable suivante, un premier couple magnétique exercé sur la bascule portant le deuxième aimant présente un premier sens sur un premier tronçon et un deuxième sens, opposé au premier sens, sur un deuxième tronçon de la distance correspondante, le premier sens correspondant à un couple de rappel en direction de l'élément mobile pour une partie de contact de ladite bascule, alors que le deuxième sens tend à écarter cette partie de contact de l'élément mobile. La structure magnétique est agencée le long de l'axe de déplacement de manière que, pour chaque position de la pluralité de positions stables discrètes, le premier couple magnétique est appliqué dans le premier sens susmentionné.To this end, the present invention relates to a watch movement comprising a mobile element, which is capable of being driven along a displacement axis and of being momentarily immobilized along this displacement axis successively in a plurality of discrete stable positions, and a device for positioning this movable element in any one of the plurality of discrete stable positions. The positioning device comprises a rocker and a magnetic system formed of a first magnet, a second magnet secured to the rocker and a magnetic structure secured to the movable element, this magnetic structure being made of a material to high magnetic permeability and exhibiting, relative to the axis of movement, a transverse dimension which varies periodically so as to define a plurality of periods which correspond, for the mobile element, respectively to the distances to be traveled between the positions of the plurality of discrete stable positions. The first and second magnets are arranged so that their magnetic axes have opposite directions, in projection on a reference axis passing substantially through the respective centers of these first and second magnets, and respectively on one side and the other of the magnetic structure so that when the movable member is driven along its axis of movement from any stable position to a next stable position, the magnetic structure passes between the first and second magnets. The magnetic system is further arranged so that, when the movable member is driven along its axis of movement from any stable position to a next stable position, a first magnetic torque exerted on the rocker carrying the second magnet presents a first direction on a first section and a second direction, opposite to the first direction, on a second section of the corresponding distance, the first direction corresponding to a return torque in the direction of the movable element for a contact part of said rocker , while the second direction tends to separate this contact part of the movable element. The magnetic structure is arranged along the axis of movement so that, for each position of the plurality of discrete stable positions, the first magnetic torque is applied in the aforementioned first direction.
Le système magnétique engendre un deuxième couple magnétique qui s'exerce directement sur la structure magnétique et ainsi sur l'élément mobile. Selon une variante principale, ce deuxième couple magnétique a une valeur nulle, correspondant à une position d'équilibre magnétique stable pour l'élément mobile, alors que le premier couple magnétique est appliqué à la bascule dans le premier sens.The magnetic system generates a second magnetic torque which is exerted directly on the magnetic structure and thus on the mobile element. According to a main variant, this second magnetic torque has a zero value, corresponding to a stable magnetic equilibrium position for the mobile element, while the first magnetic torque is applied to the rocker in the first direction.
Selon une variante avantageuse, la bascule est associée à un ressort qui exerce une force élastique sur cette bascule de manière à engendrer un couple mécanique qui pousse la partie de contact de cette bascule en direction d'une denture que présente l'élément mobile et dans laquelle cette partie de contact pénètre pour positionner mécaniquement l'élément mobile.According to an advantageous variant, the latch is associated with a spring which exerts an elastic force on this latch so as to generate a mechanical torque which pushes the contact part of this latch in the direction of a toothing that the mobile element has and in which this contact part penetrates to mechanically position the movable element.
Selon une application principale, l'élément mobile forme un support d'affichage d'une donnée de calendrier. En particulier, l'élément mobile est un anneau des quantièmes.According to a main application, the mobile element forms a display medium for calendar data. In particular, the mobile element is a date ring.

On commencera par décrire à l'aide des
Le système magnétique 2 comprend un premier aimant fixe 4, un élément à haute perméabilité magnétique 6 et un deuxième aimant 8 qui est mobile, selon un axe de déplacement confondu ici à l'axe d'alignement 10 de ces trois éléments magnétiques, relativement à l'ensemble formé par le premier aimant 4 et l'élément 6. L'élément 6 est agencé entre le premier aimant et le deuxième aimant, proche du premier aimant et dans une position déterminée relativement à celui-ci. Dans une variante particulière, la distance entre l'élément 6 et l'aimant 4 est inférieure ou sensiblement égale à un dixième de la longueur de cet aimant selon son axe d'aimantation. L'élément 6 est constitué par exemples d'un acier au carbone, de carbure tungstène, de nickel, de FeSi ou FeNi, ou d'autres alliages avec du cobalt comme le Vacozet® (CoFeNi) ou le Vacoflux® (CoFe). Dans une variante avantageuse, cet élément à haute perméabilité magnétique est constitué d'un verre métallique à base de fer ou cobalt. L'élément 6 est caractérisé par un champ de saturation Bs et une perméabilité µ. Les aimants 4 et 8 sont par exemples en ferrite, en FeCo ou PtCo, en terres rares comme NdFeB ou SmCo. Ces aimants sont caractérisés par leur champ rémanent Br1 et Br2.The
L'élément à haute perméabilité magnétique 6 présente un axe central qui est de préférence sensiblement confondu avec l'axe d'aimantation du premier aimant 4 et également avec l'axe d'aimantation du deuxième aimant 8, cet axe central étant ici confondu avec l'axe d'alignement 10. Les sens d'aimantation respectifs des aimants 4 et 8 sont opposés. Ces premier et deuxième aimants ont donc des polarités opposées et ils sont susceptibles de subir entre eux un mouvement relatif sur une certaine distance relative. La distance D entre l'élément 6 et l'aimant mobile 8 indique l'éloignement de cet aimant mobile relativement à l'ensemble formé des deux autres éléments du système magnétique. On notera que l'axe 10 est prévu ici linéaire, mais ceci est une variante non limitative. En effet, l'axe de déplacement peut aussi être courbe, comme dans les réalisations qui seront décrits par la suite. Dans ce dernier cas, l'axe central de l'élément 6 est de préférence approximativement tangent à l'axe de déplacement courbe de l'aimant mobile et ainsi le comportement d'un tel système magnétique est, en première approximation, semblable à celui du système magnétique décrit ici. Ceci est d'autant plus vrai que le rayon de courbure est grand relativement à la distance maximale possible entre l'élément 6 et l'aimant mobile 8. Dans une variante préférée, comme représentée à la
Les deux aimants 4 et 8 sont agencés en répulsion magnétique de sorte que, en l'absence de l'élément à haute perméabilité magnétique 6, une force de répulsion magnétique tend à éloigner ces deux aimants l'un de l'autre. Cependant, de manière surprenante, l'agencement entre ces deux aimants de l'élément 6 inverse le sens de la force magnétique exercée sur l'aimant mobile lorsque la distance entre cet aimant mobile et l'élément 6 est suffisamment petite, de sorte que l'aimant mobile subit alors une force d'attraction magnétique. La courbe 12 de la
La force magnétique exercée sur l'aimant mobile est une fonction continue de la distance D et elle a donc une valeur nulle à la distance Dinv pour laquelle il y a inversion de cette force magnétique (
En référence aux
Le mouvement horloger 20 comprend un anneau des quantièmes 22, qui est susceptible d'être entraîné en rotation dans le sens horaire, selon un axe de déplacement circulaire 24, et d'être immobilisé momentanément le long de cet axe de déplacement successivement dans une pluralité de positions stables discrètes. Le mouvement horloger comprend un dispositif de positionnement de l'anneau des quantièmes dans l'une quelconque des positions angulaires de la pluralité de positions stables discrètes, ce dispositif de positionnement étant formé de deux systèmes complémentaires qui sont associés, à savoir un système mécanique, formé par une bascule 30 associée à un ressort 32 et par une denture 26 comprenant une pluralité de creux ou encoches 28 dans lesquels vient s'insérer successivement une partie d'extrémité 31 de la bascule (laquelle définit une partie de contact avec la denture) lorsque l'anneau est successivement positionné dans les positions angulaires de ladite pluralité de positions stables discrètes, et un système magnétique formé d'un premier aimant fixe 34, d'un deuxième aimant 36 solidaire de la bascule et d'une structure magnétique 38 solidaire de l'anneau 22.The
La structure magnétique 38 est constituée d'un matériau à haute perméabilité magnétique et présente, relativement à l'axe de déplacement de l'anneau 22, une dimension transversale qui varie périodiquement en définissant une pluralité de périodes angulaires θP qui correspondent, pour l'anneau mobile, aux distances angulaires qu'il doit parcourir entre ses positions d'affichage (pluralité de positions stables discrètes). Plus particulièrement, dans la variante décrite aux
Le premier aimant 34 et le deuxième aimant 36 sont agencés respectivement d'un côté et de l'autre de la structure magnétique 38 avec leurs axes magnétiques sensiblement alignés sur un axe de référence AREF qu'ils définissent (cet axe passant sensiblement par leurs centres respectifs). Les axes magnétiques des deux aimants présentent des sens opposés (aimants avec leurs polarités opposées). Ensuite, ces premier et deuxième aimants, et par conséquent la bascule 30, sont agencés de sorte que, lorsque l'anneau des quantièmes est entraîné le long de son axe de déplacement 24, la structure magnétique passe entre ces deux aimants. On utilise le phénomène physique du système magnétique décrit aux
La
De plus, le système magnétique du dispositif de positionnement de l'invention engendre en outre un deuxième couple magnétique sur l'anneau 22 grâce à une force magnétique exercée par le système magnétique directement sur la structure magnétique 38, ce deuxième couple magnétique renforce le premier couple magnétique puisque la structure magnétique (la denture magnétique) est agencée de manière que le deuxième couple magnétique est relativement faible, de préférence quasi nul, lorsque l'anneau est dans l'une quelconque de ses positions angulaires d'affichage, et qu'il augmente relativement rapidement de part et d'autre de chaque position d'affichage de manière à s'opposer dans un premier temps à un déplacement de l'anneau hors de la position d'affichage qu'il occupe, en rappelant l'anneau vers cette position d'affichage. L'évolution du deuxième couple magnétique est représentée à la
Sur le graphe de la
Le premier couple magnétique exercé par le premier aimant et la structure magnétique sur la bascule 30 portant le deuxième aimant, en fonction de la position angulaire de l'anneau 22 (et donc de la structure magnétique 38) sur une période angulaire entre deux positions d'affichage de l'anneau, présente un premier sens (sens négatif à la
On observe que la première partie TR1a du premier tronçon d'une période donnée suit directement la deuxième partie TR1 b du premier tronçon de la période qui précède cette période donnée. Ainsi, entre les deuxièmes tronçons TR2, le premier couple magnétique est appliqué dans le premier sens sur des tronçons continus formés chacun d'une première partie TR1a et d'une deuxième partie TR1b situées respectivement des deux côtés d'une position stable Pn. De préférence, le premier couple magnétique (couple fonctionnel 54) présente une valeur négative maximale (c'est-à-dire maximale en valeur absolue) pour une position angulaire PCM proche de chaque position stable discrète Pn. Dans une variante avantageuse, cette valeur négative maximale est atteinte sensiblement à chaque position stable discrète Pn.It is observed that the first part TR1a of the first section of a given period directly follows the second part TR1b of the first section of the period preceding this given period. Thus, between the second sections TR2, the first magnetic torque is applied in the first direction to continuous sections each formed of a first part TR1a and a second part TR1b located respectively on both sides of a stable position P n . Preferably, the first magnetic couple (functional couple 54) has a maximum negative value (that is to say maximum in absolute value) for an angular position P CM close to each discrete stable position P n . In an advantageous variant, this maximum negative value is reached substantially at each discrete stable position P n .
On remarquera que la partie d'extrémité 31 de la bascule qui presse contre la denture comprend ici le deuxième aimant 36. Dans la variante représentée, il est prévu que le support amagnétique formant cette partie d'extrémité et portant le deuxième aimant soit en butée contre la denture 26 de manière que ce deuxième aimant puisse s'approcher des dents magnétiques 40 sans toutefois entrer en contact avec l'anneau. Dans une variante, le deuxième aimant présente une surface de contact avec la denture, cette surface de contact étant durcie par un traitement approprié. Dans une autre variante, la partie du deuxième aimant située du côté de la denture est protégée par une couche de protection déposée sur le deuxième aimant, cette couche de protection étant en contact avec la denture.It will be noted that the
Sur le graphe de la
Le deuxième couple magnétique présente une valeur sensiblement nulle à la position Pn définissant le début d'une période angulaire entre deux positions d'affichage. A chaque position Pn (n étant un nombre naturel), la structure magnétique et par conséquent l'anneau 22 se trouvent dans une position magnétique stable car la pente négative de la courbe 60 à cette position Pn indique que le deuxième couple magnétique tend à ramener l'anneau vers cette position lorsqu'il s'en écarte (sens positif de l'angle de rotation est le sens horaire). De préférence, l'anneau et la bascule sont agencés de manière que chaque position Pn de la pluralité de positions stables discrètes correspond à une position magnétique stable, comme c'est le cas dans le premier mode de réalisation. Le premier couple magnétique est appliqué à la bascule dans le premier sens lorsque l'anneau est dans une quelconque position d'équilibre magnétique stable. Dans une variante avantageuse représentée aux
Le deuxième couple magnétique 60 présente dans chaque période angulaire une valeur négative sur un premier tronçon TR3 et une valeur positive sur un deuxième tronçon TR4. Chacun de ces deux tronçons s'étend sensiblement sur une demi-période. On remarquera que ce deuxième couple magnétique présente une valeur nulle entre ces deux tronçons, cette position correspondant à une position d'équilibre magnétique instable. Dans cette position, l'axe de référence AREF passe sensiblement entre deux dents magnétiques 40 et par conséquent entre deux encoches ou creux 28 de la denture 26, ces encoches ou creux étant alignés radialement avec les dents magnétiques 40.The second
Le ressort 32 pressant sur la bascule engendre un couple mécanique appliqué par la bascule à l'anneau 22. On remarquera que ce couple mécanique peut être relativement faible étant donné les premier et deuxième couples magnétiques engendrés par le système magnétique qui s'exercent sur l'anneau dans un même sens que ce couple mécanique lorsque l'anneau est dans l'une quelconque position de la pluralité de positions d'affichage. On remarquera encore que le couple mécanique peut être supérieur au premier couple magnétique appliqué dans le deuxième sens, c'est-à-dire à sa valeur positive maximale sur le deuxième tronçon TR2, de sorte que la partie 31 de la bascule reste continument en appui contre la denture 26 de cette bascule. Cependant, dans une autre variante, le couple mécanique est inférieur à cette valeur positive maximale sur une certaine distance angulaire de pivotement de la bascule. Toutefois, dans ce dernier cas, la rigidité du ressort est avantageusement sélectionnée pour que ce ressort limite, dans le deuxième tronçon TR2, l'éloignement de l'aimant 36, porté par la partie d'extrémité 31 de la bascule, relativement à la structure magnétique 38. Si tel n'est pas le cas, alors un élément du mouvement horloger doit présenter une fonction de butée pour la bascule lorsque la partie 31 s'éloigne de la denture, de manière à limiter son éloignement de cette denture dans le deuxième tronçon TR2 de chaque période.The
On remarquera que les deux forces magnétiques, qui s'exercent respectivement sur la bascule via l'aimant qu'elle porte et sur l'anneau via la structure magnétique qu'il porte ou dont il est formé, sont des vecteurs qui ont chacun une certaine intensité variable et également une direction variable dans le plan général de l'anneau et de la bascule. Ces deux paramètres (intensité et direction) interviennent dans le premier couple magnétique et dans le deuxième couple magnétique. Le premier couple magnétique est défini relativement à l'axe de pivotement de la bascule alors que le deuxième couple magnétique est défini relativement à l'axe de rotation géométrique de l'anneau.It will be noted that the two magnetic forces, which are exerted respectively on the rocker via the magnet which it carries and on the ring via the magnetic structure which it carries or of which it is formed, are vectors which each have a certain variable intensity and also a variable direction in the general plane of the ring and the rocker. These two parameters (intensity and direction) intervene in the first magnetic couple and in the second magnetic couple. The first magnetic couple is defined relative to the pivot axis of the rocker while the second magnetic couple is defined relative to the geometric axis of rotation of the ring.
Dans le cadre d'une variante de réalisation, avec une bascule agencée symétriquement à la bascule représentée aux

Un deuxième mode de réalisation de l'invention est représenté à la
Comme dans le premier mode de réalisation, les premier et deuxième couples magnétiques agissent constructivement avec le couple mécanique engendré par le ressort 32 pour positionner l'anneau dans l'une quelconque position de la pluralité de positions d'affichage et pour le maintenir dans cette position en l'absence d'un entraînement de l'anneau par son mécanisme d'entraînement agencé dans le mouvement horloger (mécanisme connu de l'homme du métier). On notera que le mécanisme d'entraînement doit donc vaincre les premier et deuxième couples magnétiques ainsi que le couple mécanique pour entraîner l'anneau d'une position d'affichage stable à une position d'affichage stable suivante. Toutefois, comme déjà évoqué, le deuxième couple magnétique est substantiellement conservateur. De même, le premier couple magnétique ainsi que le couple mécanique peuvent redonner une certaine énergie à l'anneau dans la deuxième moitié du déplacement entre deux positions d'affichage stables. Ceci dépend aussi du profil de la denture et bien sûr de la force de frottement de la bascule sur la denture de l'anneau.As in the first embodiment, the first and second magnetic pairs act constructively with the mechanical torque generated by the
Outre les deux couples magnétiques qui agissent de concert sur l'anneau pour le positionner et le stabiliser, le dispositif de positionnement selon l'invention est remarquable par le fait que le premier couple magnétique qui s'exerce sur la bascule diminue rapidement dès que la partie d'extrémité 31 de la bascule commence à sortir d'une des encoches 28 et change ensuite de signe lorsque l'anneau est entraîné plus avant pour passer d'une position d'affichage à une autre. En d'autres termes, le couple magnétique diminue dès que la bascule est éloignée de l'anneau par l'intermédiaire de sa denture, ce qui diminue donc rapidement le couple de positionnement magnétique dès qu'on s'éloigne d'une position stable discrète. En effet, lorsque la bascule s'écarte de la denture, le premier couple magnétique diminue fortement et s'inverse même, de sorte que le passage d'une dent est grandement facilité et demande ainsi peu d'énergie. On remarquera que ce comportement est à l'inverse du couple mécanique exercé par le ressort sur la bascule, la force mécanique de rappel en direction de l'anneau augmentant lorsque la partie d'extrémité de la bascule sort d'une encoche ou plus généralement lorsqu'elle s'écarte pour permettre le passage d'une dent de la denture de positionnement (laquelle peut aussi servir à l'entraînement de l'anneau).In addition to the two magnetic couples which act in concert on the ring to position it and stabilize it, the positioning device according to the invention is remarkable in that the first magnetic couple which is exerted on the rocker decreases rapidly as soon as the
Les éléments magnétiques 86 ont une forme oblongue avec les deux extrémités tronconiques. Dans une variante, ces éléments magnétiques ont simplement une forme rectangulaire. En référence aux

- Timepiece movement comprising a movable element (22, 22A, 82), which is capable of being driven along an axis of displacement (24) and of being momentarily immobilised in any one stable position of a plurality of discrete stable positions, and a device for positioning said movable element in any one of the plurality of discrete stable positions, characterized in that the positioning device comprises a lever (30) and a magnetic system formed of a first magnet (34), a second magnet (36) integral with the lever and a magnetic structure (38, 38A, 84) integral with the movable element, said magnetic structure being formed of a highly magnetically permeable material and having, relative to said axis of displacement, a transverse dimension that varies periodically to define a plurality of periods respectively corresponding to the distances to be covered by the movable element between the positions of the plurality of discrete stable positions; in that the first and second magnets are arranged such that their magnetic axes are in opposite directions, in projection onto a reference axis (AREF) substantially passing through the respective centres of said first and second magnets, and respectively on either side of the magnetic structure so that, when the movable element is driven along its displacement axis from any one stable position to the next stable position, the magnetic structure moves between the first and second magnets, the magnetic system being further arranged such that, when the movable element is driven along its axis of displacement, from any one stable position to the next stable position, a first magnetic torque exerted on the lever carrying the second magnet has a first direction over a first section (TR1a, TR1b) and a second direction, opposite to the first direction, over a second section (TR2) of the corresponding distance, said first direction corresponding to a return torque towards the movable element for a contact portion of said lever; and in that the magnetic structure is arranged along said axis of displacement such that, in each position of the plurality of discrete stable positions, said first magnetic torque is applied in said first direction.
- Timepiece movement according to claim 1, characterized in that said reference axis is substantially orthogonal to said axis of displacement (24); and in that the first and second magnets are arranged such that their magnetic axes are substantially aligned on said reference axis (AREF).
- Timepiece movement according to claim 1 or 2, characterized in that the magnetic system produces a second magnetic torque that is exerted directly on the magnetic structure (38, 38A, 84) and thus on the movable element, said second magnetic torque having a zero value, corresponding to a stable position of magnetic equilibrium for the movable element, whereas the first magnetic torque is applied in said first direction to said lever.
- Timepiece movement according to claim 3, characterized in that said movable element and said lever are arranged such that each position of said plurality of discrete stable positions substantially corresponds to a stable magnetic position.
- Timepiece movement according to claim 4, characterized in that, in each stable magnetic position of the movable element, the first magnetic torque applied to the lever has a value close to, or substantially equal to, the maximum value of said first magnetic torque in said first section.
- Timepiece movement according to any of the preceding claims, characterized in that the movable element or the magnetic structure comprises a toothing (26) against which comes to bear said contact portion (31) of the lever at least when said first magnetic torque is applied in said first direction to said lever, the toothing and the lever being arranged such that said contact portion is located at the bottom of said toothing in each position of said plurality of discrete stable positions.
- Timepiece movement according to claim 6, characterized in that said lever is associated with a spring (32) which exerts an elastic force on said lever to produce a mechanical torque on said contact portion that pushes the latter towards said toothing.
- Timepiece movement according to any of the preceding claims, characterized in that said magnetic structure (38, 38A) extends continuously along the movable element on said axis of displacement (24).
- Timepiece movement according to any of claims 1 to 7, characterized in that said magnetic structure (84) is formed of a plurality of distinct magnetic elements (86) arranged along the movable element on said axis of displacement (24) to define said plurality of periods and with a space containing no highly magnetically permeable material between any two successive magnetic elements.
- Timepiece movement according to any of the preceding claims, characterized in that said movable element has an annular shape, said movable element being arranged to rotate on itself so that said axis of displacement is a circular axis.
- Timepiece movement according to claim 10, characterized in that the movable element forms a display support for calendar information.
- Timepiece movement according to claim 11, characterized in that the movable element is a date ring.
