Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the various figures, the same references denote identical or similar elements.

La figure 1 représente une pièce d'horlogerie 1 telle qu'une montre, comprenant :

  • un boîtier 2,
  • un mouvement horloger 3 contenu dans le boîtier 2,
  • généralement, un remontoir 4,
  • un cadran 5,
  • un verre 6 recouvrant le cadran 5,
  • un indicateur de temps 7, comprenant par exemple deux aiguilles 7a, 7b respectivement pour les heures et les minutes, disposé entre le verre 6 et le cadran 5 et actionné par le mouvement horloger 3.
The figure 1 represents a timepiece 1 such as a watch, comprising:
  • a box 2,
  • a watch movement 3 contained in the case 2,
  • generally, a winder 4,
  • a dial 5,
  • a glass 6 covering the dial 5,
  • a time indicator 7, comprising for example two hands 7a, 7b respectively for the hours and the minutes, arranged between the glass 6 and the dial 5 and actuated by the watch movement 3.

Comme représenté schématiquement sur la figure 2, le mouvement horloger 3 peut comprendre par exemple :

  • un dispositif 8 de stockage d'énergie mécanique, généralement un ressort de barillet,
  • une transmission mécanique 9 mue par le dispositif 8 de stockage d'énergie mécanique,
  • l'indicateur de temps 7 susmentionné,
  • un organe de distribution d'énergie 10 (par exemple une roue d'échappement),
  • une ancre 11 adaptée pour séquentiellement retenir et libérer l'organe de distribution d'énergie 10,
  • un régulateur 12, qui est un mécanisme comportant un organe réglant oscillant contrôlant l'ancre 11 pour la déplacer régulièrement de façon que l'organe de distribution d'énergie soit déplacé pas à pas à intervalles de temps constants.
As shown schematically on the figure 2 , the watch movement 3 can include, for example:
  • a device 8 for storing mechanical energy, generally a barrel spring,
  • a mechanical transmission 9 driven by the device 8 for storing mechanical energy,
  • the aforementioned time indicator 7,
  • an energy distribution member 10 (for example an escape wheel),
  • an anchor 11 adapted to sequentially retain and release the energy distribution member 10,
  • a regulator 12, which is a mechanism comprising an oscillating regulating member controlling the anchor 11 to move it regularly so that the energy distribution member is moved step by step at constant time intervals.

L'ancre 11 et le régulateur 12 forment un mécanisme 13 monolithique, comme il sera expliqué ci-après.The anchor 11 and the regulator 12 form a monolithic mechanism 13, as will be explained below.

Le mouvement horloger 3 va maintenant être expliqué plus en détail à l'aide de la figure 3, qui représente un cas particulier où le mécanisme 13 (en dehors du dispositif de blocage à vis décrit ci-après) est un système monolithique formé dans une même plaque 14 (habituellement plane) et dont les pièces mobiles sont conçues pour se déplacer essentiellement dans un plan moyen de ladite plaque 14.Watch movement 3 will now be explained in more detail using the figure 3 , which represents a particular case where the mechanism 13 (apart from the screw locking device described below) is a system monolithic formed in the same plate 14 (usually flat) and the moving parts of which are designed to move essentially in a mean plane of said plate 14.

La plaque 14 peut être de faible épaisseur, par exemple environ 0,05 à environ 1 mm, selon la nature du matériau de la plaque 14.The plate 14 may be of small thickness, for example about 0.05 to about 1 mm, depending on the nature of the material of the plate 14.

La plaque 14 peut avoir des dimensions transversales, dans le plan XY de la plaque (notamment largeur et longueur, ou diamètre), comprises entre environ 10 mm et 40 mm. X et Y sont deux axes perpendiculaires définissant le plan de la plaque 14.The plate 14 may have transverse dimensions, in the XY plane of the plate (in particular width and length, or diameter), of between approximately 10 mm and 40 mm. X and Y are two perpendicular axes defining the plane of plate 14.

La plaque 14 peut être fabriquée en tout matériau rigide adapté, ayant de préférence un module d'Young faible pour présenter de bonnes propriétés d'élasticité et une fréquence d'oscillation basse. Des exemples de matériaux utilisables pour réaliser la plaque 14 incluent le silicium, le nickel, l'alliage fer/nickel, l'acier, le titane. Dans le cas du silicium, l'épaisseur de la plaque 14 peut par exemple être comprise entre 0,2 et 0,6 mm.The plate 14 can be made of any suitable rigid material, preferably having a low Young's modulus to exhibit good elasticity properties and a low oscillation frequency. Examples of materials that can be used to make the plate 14 include silicon, nickel, iron / nickel alloy, steel, titanium. In the case of silicon, the thickness of the plate 14 can for example be between 0.2 and 0.6 mm.

Les différents organes formés dans la plaque 14, sont obtenus par réalisation d'ouvertures dans la plaque 14, obtenues par tout procédé de fabrication utilisé en micromécanique, en particulier les procédés utilisés pour la fabrication des MEMS.The various members formed in the plate 14 are obtained by making openings in the plate 14, obtained by any manufacturing process used in micromechanics, in particular the processes used for manufacturing MEMS.

Dans le cas d'une plaque 14 de silicium, la plaque peut être localement évidée par exemple par gravure ionique réactive profonde (DRIE - "Deep Reactive Ion Etching") ou éventuellement par découpe laser pour les petites séries.In the case of a silicon wafer 14, the wafer can be locally hollowed out, for example by deep reactive ion etching (DRIE - "Deep Reactive Ion Etching") or possibly by laser cutting for small series.

Dans le cas d'une plaque 14 de fer/nickel, la plaque pourrait être notamment réalisée par le procédé LIGA, ou par découpe laser.In the case of an iron / nickel plate 14, the plate could in particular be produced by the LIGA process, or by laser cutting.

Dans le cas d'une plaque 14 d'acier ou de titane, la plaque 14 peut être évidée par exemple par électroérosion par fil (WEDM).In the case of a plate 14 of steel or titanium, the plate 14 can be hollowed out, for example by wire spark erosion (WEDM).

Les parties constitutives du mécanisme vont maintenant être décrites plus en détail. Certaines de ces parties sont rigides et d'autres (notamment celles dénommées « branches élastiques ») sont élastiquement déformables, essentiellement en flexion. La différence entre les parties rigides et les parties élastiques, est leur raideur dans le plan XY de la plaque 14, qui est due à leur forme et en particulier à leur élancement. L'élancement peut être mesuré notamment par le rapport d'élancement (rapport longueur / largeur de la partie concernée). Par exemple, les parties rigides ont une raideur au moins environ 100 fois plus élevée dans le plan XY, que les parties élastiques. Des dimensions typiques pour les liaisons élastiques, par exemple les branches élastiques qui seront décrites ci-après, incluent des longueurs comprises par exemple entre 5 et 13 mm et des largeurs comprises par exemple entre 0,01 mm (10 µm) et 0,04 mm (40 µm), notamment environ 0,025 mm (25 µm). Compte tenu des largeurs des poutres et de l'épaisseur de la plaque 14, le rapport d'aspect de ces poutres en coupe longitudinale est compris entre 5 et 60. Le rapport d'aspect le plus grand possible est à privilégier pour limiter les modes d'oscillation hors plan.The constituent parts of the mechanism will now be described in more detail. Some of these parts are rigid and others (in particular those called “elastic branches”) are elastically deformable, essentially in bending. The difference between the rigid parts and the elastic parts is their stiffness in the XY plane of the plate 14, which is due to their shape and in particular to their slenderness. The slenderness can be measured in particular by the slenderness ratio (length / width ratio of the part concerned). For example, the rigid parts have a stiffness at least about 100 times greater in the XY plane than the elastic parts. Typical dimensions for elastic links, for example the elastic legs which will be described hereinafter, include lengths of for example between 5 and 13 mm and widths of for example between 0.01 mm (10 µm) and 0.04 mm (40 µm), especially about 0.025 mm (25 µm). Taking into account the widths of the beams and the thickness of the plate 14, the aspect ratio of these beams in longitudinal section is between 5 and 60. The largest possible aspect ratio is to be preferred to limit the modes. oscillation out of plane.

La plaque 14 forme un cadre externe 15 fixe qui est fixé à une platine de support 14a, par exemple par des vis ou similaires (non représentées) traversant des trous 15a du cadre 15. La platine de support 14a est solidarisée au boîtier 2 de la pièce d'horlogerie 1. Le cadre 15 peut entourer au moins partiellement l'organe de distribution d'énergie 10, l'ancre 11 et le régulateur 12.The plate 14 forms a fixed external frame 15 which is fixed to a support plate 14a, for example by screws or the like (not shown) passing through holes 15a of the frame 15. The support plate 14a is secured to the housing 2 of the timepiece 1. The frame 15 can at least partially surround the energy distribution member 10, the anchor 11 and the regulator 12.

L'organe de distribution d'énergie 10 peut être une roue d'échappement montée rotative par exemple sur la platine de support 14a, de façon à pouvoir tourner autour d'un axe de rotation Z0 perpendiculaire au plan XY de la plaque 14. L'organe de distribution d'énergie 10 est sollicité par le dispositif de stockage d'énergie 8 dans un unique sens de rotation 16.The energy distribution member 10 can be an escape wheel mounted to rotate, for example on the support plate 14a, so as to be able to rotate about an axis of rotation Z0 perpendicular to the XY plane of the plate 14. L the energy distribution member 10 is requested by the energy storage device 8 in a single direction of rotation 16.

L'organe de distribution d'énergie 10 présente des dents externes 17.The energy distribution member 10 has external teeth 17.

L'ancre 11 est une pièce rigide qui peut comporter un corps rigide 18 s'étendant par exemple parallèlement à l'axe X et deux bras latéraux rigides parallèles 19, 20 s'étendant par exemple parallèlement à l'axe Y de part et d'autre de l'organe de distribution d'énergie 10. Les bras 19, 20 comportent respectivement deux organes d'arrêt 21, 22 en forme de doigts faisant saillie l'un vers l'autre dans la direction de l'axe X à partir des bras 19, 20.The anchor 11 is a rigid part which may comprise a rigid body 18 extending for example parallel to the X axis and two parallel rigid side arms 19, 20 extending for example parallel to the Y axis on both sides. 'other of the energy distribution member 10. The arms 19, 20 respectively comprise two stop members 21, 22 in the form of fingers projecting towards each other in the direction of the axis X to from arms 19, 20.

L'ancre 11 est reliée élastiquement au cadre 15, de façon à pouvoir se déplacer parallèlement à l'axe X, selon une direction de translation 02. Avantageusement, l'ancre 11 peut être reliée au cadre 15 par une suspension élastique, comprenant par exemple deux branches élastiques 23 sensiblement parallèles à l'axe Y. Eventuellement, les branches élastiques 23 peuvent être reliées au corps 18 et disposées de part et d'autre des bras latéraux 19, 20, en encadrant ces bras latéraux.The anchor 11 is elastically connected to the frame 15, so as to be able to move parallel to the axis X, in a direction of translation 02. Advantageously, the anchor 11 can be connected to the frame 15 by an elastic suspension, comprising by example two elastic branches 23 substantially parallel to the Y axis. Optionally, the elastic branches 23 can be connected to the body 18 and arranged on either side of the lateral arms 19, 20, framing these lateral arms.

L'ancre 11 peut comporter en outre un bras rigide 24 s'étendant selon l'axe Y vers le régulateur 12, à l'opposé du bras 20.The anchor 11 may further include a rigid arm 24 extending along the Y axis towards the regulator 12, opposite the arm 20.

L'ancre 11 peut en outre comporter un organe élastique monostable 11a, qui peut se présenter sous la forme d'une languette élastique dont l'extrémité libre vient porter sur les dents 17 de l'organe de distribution d'énergie 10. L'organe élastique monostable 11a peut être relié au bras rigide 19 de l'ancre 11, par exemple par une suspension élastique comprenant deux branches élastiques parallèles 11b s'étendant selon l'axe Y depuis l'extrémité libre du bras rigide 19, en prolongeant le bras rigide 19 jusqu'à un support rigide 11c qui porte l'organe élastique monostable 11a. L'organe élastique monostable 11a peut s'étendre selon l'axe Y en direction du régulateur 12, à partir du support rigide 11c. L'organe élastique monostable 11a sert à ce que l'organe de distribution d'énergie 10 transfère une énergie mécanique précisément déterminée au régulateur, à chaque cycle de fonctionnement du mouvement horloger 3, comme expliqué dans la demande de brevet européen N° 14197015 ( EP3032350 ).The anchor 11 may further include a monostable elastic member 11a, which may be in the form of an elastic tongue, the free end of which bears on the teeth 17 of the energy distribution member 10. The monostable elastic member 11a can be connected to the rigid arm 19 of the anchor 11, for example by an elastic suspension comprising two parallel elastic branches 11b extending along the axis Y from the free end of the rigid arm 19, by extending the rigid arm 19 to a rigid support 11c which carries the monostable elastic member 11a. The monostable elastic member 11a can extend along the Y axis in the direction of the regulator 12, from the rigid support 11c. The monostable elastic member 11a is used for the energy distribution member 10 to transfer a precisely determined mechanical energy to the regulator, at each operating cycle of the watch movement 3, as explained in European patent application No. 14197015 ( EP3032350 ).

Le mécanisme 13 comporte en outre un organe d'équilibrage 25, qui peut être formé d'une pièce avec le cadre 15 et qui est porté par le cadre 15 pour osciller parallèlement à l'axe X, selon la direction de translation 02. L'organe d'équilibrage 25 peut par exemple comporter :

  • un corps rigide 26 s'étendant parallèlement à l'axe X, symétriquement au corps 18 de l'ancre par rapport à un axe de symétrie Y0 parallèle à l'axe Y susmentionné,
  • et un bras rigide 28 s'étendant selon l'axe Y vers le régulateur 12, symétriquement au bras 24 de l'ancre par rapport à l'axe de symétrie Y0.
The mechanism 13 further comprises a balancing member 25, which can be formed integrally with the frame 15 and which is carried by the frame 15 to oscillate parallel to the axis X, in the direction of translation 02. L 'balancing member 25 may for example comprise:
  • a rigid body 26 extending parallel to the X axis, symmetrically to the body 18 of the anchor with respect to an axis of symmetry Y0 parallel to the aforementioned Y axis,
  • and a rigid arm 28 extending along the axis Y towards the regulator 12, symmetrically to the arm 24 of the anchor with respect to the axis of symmetry Y0.

L'organe d'équilibrage 25 peut également être à l'intérieur du cadre 15 et peut être relié au cadre 15 par une suspension élastique, comprenant par exemple deux branches élastiques 27 sensiblement parallèles à l'axe Y et symétriques des branches élastiques 23 de l'ancre 11. Eventuellement, les branches élastiques 23 peuvent être reliées au corps 26 de l'organe d'équilibrage 25.The balancing member 25 can also be inside the frame 15 and can be connected to the frame 15 by an elastic suspension, comprising for example two elastic branches 27 substantially parallel to the Y axis and symmetrical with the elastic branches 23 of anchor 11. Optionally, the elastic branches 23 can be connected to the body 26 of the balancing member 25.

L'ancre 11 et l'organe d'équilibrage 25 sont chacun montés sur le cadre 15 pour osciller en translation circulaire, avec une amplitude d'oscillation dans la direction de translation 02 et une amplitude d'oscillation secondaire, non-nulle, perpendiculairement à la deuxième direction de translation. Ladite amplitude d'oscillation dans la direction de translation 02 est supérieure à l'amplitude d'oscillation secondaire de l'ancre et de l'organe d'équilibrage, par exemple au moins 10 fois plus grande que l'amplitude d'oscillation secondaire de l'ancre et de l'organe d'équilibrage.The anchor 11 and the balancing member 25 are each mounted on the frame 15 to oscillate in circular translation, with an amplitude of oscillation in the direction of translation 02 and a secondary amplitude of oscillation, non-zero, perpendicularly. to the second direction of translation. Said oscillation amplitude in the direction of translation 02 is greater than the secondary oscillation amplitude of the anchor and the balancing member, for example at least 10 times greater than the secondary oscillation amplitude anchor and the balancing member.

L'organe d'équilibrage 25 peut avantageusement avoir une masse sensiblement identique à celle de l'ancre 11, par exemple comprise entre 90 % et 110 % de la masse de l'ancre 11. La masse de l'organe d'équilibrage est très proche de celle de l'ancre mais n'est pas nécessairement identique pour tenir compte du fait que les contraintes appliquées à l'un ou l'autre de ces organes ne sont pas tout à fait symétriques (par exemple l'ancre est en contact avec l'organe de distribution d'énergie alors que l'organe d'équilibrage ne l'est pas).The balancing member 25 can advantageously have a mass substantially identical to that of the anchor 11, for example between 90% and 110% of the mass of the anchor 11. The mass of the balancing member is very close to that of the anchor but is not necessarily identical to take into account the fact that the stresses applied to one or the other of these members are not completely symmetrical (for example the anchor is in contact with the energy distribution member when the balancing member is not).

Le régulateur 12 est un oscillateur mécanique comportant des premier et deuxième organes réglants 29, 30 formant chacun une masse inertielle rigide, reliés chacun au cadre 15 par une suspension élastique qui est adaptée pour que les premier et deuxième organes réglants 29, 30 oscillent selon l'axe Y, dans une direction de translation O1.The regulator 12 is a mechanical oscillator comprising first and second regulating members 29, 30 each forming a rigid inertial mass, each connected to the frame 15 by an elastic suspension which is adapted so that the first and second regulating members 29, 30 oscillate according to l 'axis Y, in a direction of translation O1.

La suspension élastique est formée par l'ensemble des liaisons élastiques 31 ; 36, 55 qui relient (directement ou indirectement) les premier et deuxième organes réglants 29, 30 au cadre 15. Cette suspension élastique présente une certaine raideur globale, dont dépend la fréquence d'oscillation f des premier et deuxième organes réglants 29, 30.The elastic suspension is formed by the set of elastic links 31; 36, 55 which connect (directly or indirectly) the first and second regulating members 29, 30 to the frame 15. This elastic suspension has a certain overall stiffness, on which depends the oscillation frequency f of the first and second regulating members 29, 30.

La suspension élastique des premier et deuxième organes réglants 29, 30 peut comporter par exemple deux branches élastiques 31 pour chaque organe réglant 29, 30, s'étendant sensiblement selon l'axe X et reliées au cadre 15.The elastic suspension of the first and second regulating members 29, 30 may for example comprise two elastic branches 31 for each regulating member 29, 30, extending substantially along the X axis and connected to the frame 15.

Chacun des premier et deuxième organes réglants 29, 30 est donc monté sur le cadre 15 pour osciller en translation circulaire, avec une première amplitude d'oscillation dans la direction de translation O1 et avec une amplitude d'oscillation secondaire, non-nulle, perpendiculairement à la direction de translation O1. Ladite amplitude d'oscillation dans la direction de translation O1 est supérieure à l'amplitude d'oscillation secondaire des premier et deuxième organes réglants, par exemple au moins 10 fois plus grande que l'amplitude d'oscillation secondaire.Each of the first and second regulating members 29, 30 is therefore mounted on the frame 15 to oscillate in circular translation, with a first oscillation amplitude in the translation direction O1 and with a secondary, non-zero oscillation amplitude, perpendicular to the direction of translation O1. Said oscillation amplitude in the translation direction O1 is greater than the secondary oscillation amplitude of the first and second regulating members, for example at least 10 times greater than the secondary oscillation amplitude.

Dans l'exemple représenté, les premier et deuxième organes réglants 29, 30 peuvent présenter chacun une forme de C, avec un corps principal 32 s'étendant selon l'axe Y entre deux bras latéraux 33 s'étendant vers l'intérieur du cadre 15. Les branches élastiques 31 susmentionnées peuvent avantageusement être reliées aux extrémités libres des bras latéraux 33, ce qui permet d'avoir des branches élastiques 31 longues et donc particulièrement souples.In the example shown, the first and second regulating members 29, 30 may each have the shape of a C, with a main body 32 extending along the Y axis between two side arms 33 extending towards the inside of the frame. 15. The aforementioned elastic branches 31 can advantageously be connected to the free ends of the lateral arms 33, which makes it possible to have elastic branches 31 which are long and therefore particularly flexible.

Les premier et deuxième organes réglants 29, 30 peuvent être deux pièces symétriques par rapport à l'axe de symétrie Y0 susmentionné, de masse identique ou sensiblement identique. Ils peuvent définir entre eux un espace central libre 34.The first and second regulating members 29, 30 may be two parts symmetrical with respect to the aforementioned axis of symmetry Y0, of identical or substantially identical mass. They can define between them a free central space 34.

Les premier et deuxième organes réglants 29, 30 peuvent être reliés respectivement à l'ancre 11 et à l'organe d'équilibrage 25, par exemple par des branches élastiques d'entraînement 36. Ainsi, le premier organe réglant 29 commande les mouvements de l'ancre 11 et le deuxième organe réglant 30 commande les mouvements de l'organe d'équilibrage 25.The first and second regulating members 29, 30 can be connected respectively to the anchor 11 and to the balancing member 25, for example by elastic drive branches 36. Thus, the first regulating member 29 controls the movements of the anchor 11 and the second regulating member 30 control the movements of the balancing member 25.

Les branches élastiques d'entraînement 36 peuvent par exemple s'étendre sensiblement selon l'axe X. Les branches élastiques d'entraînement 36 peuvent notamment être reliées respectivement aux extrémités libres du bras rigide 24 de l'ancre et du bras rigide 28 de l'organe d'équilibrage.The elastic drive branches 36 can for example extend substantially along the X axis. The elastic drive branches 36 can in particular be connected respectively to the free ends of the rigid arm 24 of the anchor and of the rigid arm 28 of the anchor. 'balancing organ.

Eventuellement, chacun des premier et deuxième organes réglants 29, 30 peut comporter une échancrure 35 ouverte selon l'axe X entre le corps principal 32 et le bras rigide 33 le plus proche de l'ancre 11 ou de l'organe d'équilibrage 25, et la branche élastique d'entraînement 36 correspondante peut être reliée au corps principal 32 au fond de ladite échancrure 35, ce qui permet d'allonger les branches élastique d'entraînement 36 et donc d'en augmenter la souplesse.Optionally, each of the first and second regulating members 29, 30 may include a notch 35 open along the X axis between the main body 32 and the rigid arm 33 closest to the anchor 11 or to the balancing member 25, and the corresponding elastic drive branch 36 can be connected to the main body 32 at the bottom of said notch 35, which makes it possible to lengthen the elastic drive branches 36 and therefore increase their flexibility.

Dans l'espace intérieur libre 34 est disposé un levier d'équilibrage 37 rigide, monté pivotant autour d'un centre de rotation P central. Le levier d'équilibrage 37 peut éventuellement présenter une forme sensiblement en M, avec une partie centrale 38 en V divergeant à partir du centre de rotation P et deux bras latéraux 39.In the free interior space 34 is disposed a rigid balancing lever 37, mounted to pivot about a central center of rotation P. The balancing lever 37 may optionally have a substantially M-shaped shape, with a central V-shaped portion 38 diverging from the center of rotation P and two lateral arms 39.

Les bras latéraux 39 peuvent être reliés respectivement aux premier et deuxième organes réglants 29, 30, par exemple par deux branches élastiques 40 s'étendant sensiblement selon l'axe Y.The lateral arms 39 can be respectively connected to the first and second regulating members 29, 30, for example by two elastic branches 40 extending substantially along the Y axis.

Le levier d'équilibrage 37 peut être monté, par une suspension élastique 43, sur un support rigide 40a rigidement relié au cadre 15. Le support rigide 40a peut par exemple comporter un bras 41 s'étendant sur l'axe de symétrie Y0, depuis le cadre 15 jusqu'à une tête 42 qui peut par exemple s'étendre selon l'axe X en donnant au support 40a une forme en T.The balancing lever 37 can be mounted, by an elastic suspension 43, on a rigid support 40a rigidly connected to the frame 15. The rigid support 40a can for example include an arm 41 extending on the axis of symmetry Y0, since the frame 15 up to a head 42 which can for example extend along the X axis by giving the support 40 a T-shape.

La suspension élastique 43 peut par exemple comporter :

  • un organe pivotant rigide 44 disposé à l'intérieur du levier d'équilibrage 37, comprenant par exemple une âme centrale 45 au niveau du centre de rotation P, s'étendant selon l'axe X entre deux têtes élargies 46,
  • deux corps intermédiaires rigides 47, 48 disposés de part et d'autre de l'âme centrale 45 près du centre de rotation P,
  • deux branches élastiques 49 reliant respectivement les extrémités libres de la tête 42 du support rigide 41 au corps intermédiaire rigide 47,
  • deux branches élastiques 50 reliant respectivement le corps intermédiaire rigide 47 à l'une des extrémités libres des têtes élargies 46,
  • deux branches élastiques 51 symétriques des branches élastiques 50, reliant respectivement le corps intermédiaire rigide 48 à l'autre des extrémités libres des têtes élargies 46,
  • deux branches élastiques 52 reliant le corps intermédiaire rigide 48 respectivement aux extrémités de la partie centrale 38 du levier d'équilibrage.
The elastic suspension 43 can for example comprise:
  • a rigid pivoting member 44 arranged inside the balancing lever 37, comprising for example a central core 45 at the level of the center of rotation P, extending along the axis X between two enlarged heads 46,
  • two rigid intermediate bodies 47, 48 arranged on either side of the central web 45 near the center of rotation P,
  • two elastic branches 49 respectively connecting the free ends of the head 42 of the rigid support 41 to the rigid intermediate body 47,
  • two elastic branches 50 respectively connecting the rigid intermediate body 47 to one of the free ends of the widened heads 46,
  • two elastic branches 51 symmetrical with the elastic branches 50, respectively connecting the rigid intermediate body 48 to the other of the free ends of the widened heads 46,
  • two elastic branches 52 connecting the rigid intermediate body 48 respectively to the ends of the central part 38 of the balancing lever.

Le levier d'équilibrage 37 impose aux premier et deuxième organes réglants 29, 30 de se déplacer de façon symétrique et opposée selon la direction de translation O1, ce qui, par l'intermédiaire des branches élastiques d'entraînement 36, impose à l'ancre 11 et à l'organe d'équilibrage 25 de se déplacer de façon symétrique et opposée selon la direction de translation 02, comme représenté sur les figures 4 et 5 qui montrent les deux positions de fin de course du mécanisme 13.The balancing lever 37 requires the first and second regulating members 29, 30 to move symmetrically and opposite in the direction of translation O1, which, through the elastic drive branches 36, requires the anchor 11 and the balancing member 25 to move symmetrically and opposite in the direction of translation 02, as shown in figures 4 and 5 which show the two end positions of the mechanism 13.

Ces mouvements opposés permettent un équilibrage dynamique du mécanisme 13, qui permet de diminuer la sensibilité du mécanisme 13 aux chocs, à la gravité et plus généralement aux accélérations.These opposed movements allow dynamic balancing of the mechanism 13, which makes it possible to reduce the sensitivity of the mechanism 13 to shocks, to gravity and more generally to accelerations.

Le mécanisme 13 comporte en outre un dispositif de réglage de fréquence comprenant un organe de réglage de fréquence 53, qui permet d'effectuer un réglage fin de la fréquence d'oscillation du régulateur 12, notamment lors du montage du mouvement 3. L'organe de réglage de fréquence 53 peut par exemple être formé d'une seule pièce dans la plaque 14 avec les autres éléments du mécanisme 13 susmentionné.The mechanism 13 further comprises a frequency adjustment device comprising a frequency adjustment member 53, which makes it possible to perform a fine adjustment of the oscillation frequency of the regulator 12, in particular during the assembly of the movement 3. The member frequency adjustment 53 can for example be formed integrally in the plate 14 with the other elements of the aforementioned mechanism 13.

L'organe de réglage de fréquence 53 est relié, directement ou indirectement, à au moins un des organes réglants 29, 30 par une liaison élastique dite de réglage 36, 55. L'organe de réglage de fréquence 53 est en outre réglable en position par rapport à la platine de support 14a et au cadre 15 de façon à pouvoir déformer la liaison élastique de réglage 36, 55 et appliquer ainsi une contrainte élastique réglable sur l'organe réglant en question, de façon à influer sur la raideur globale de la suspension élastique du régulateur 12, et donc sur la fréquence f susmentionnée.The frequency adjustment member 53 is connected, directly or indirectly, to at least one of the adjustment members 29, 30 by a so-called adjustment elastic link 36, 55. The frequency adjustment member 53 is furthermore adjustable in position relative to the support plate 14a and to the frame 15 so as to be able to deform the elastic adjustment link 36, 55 and thus apply an adjustable elastic stress on the regulating member in question, so as to influence the stiffness overall of the elastic suspension of the regulator 12, and therefore on the above-mentioned frequency f.

L'organe de réglage de fréquence 53 peut par exemple être relié au cadre 15 par deux branches élastiques 54 s'étendant selon l'axe Y.The frequency adjustment member 53 can for example be connected to the frame 15 by two elastic branches 54 extending along the Y axis.

Dans l'exemple représenté sur la figure 3, la liaison élastique de réglage 36, 55 comporte deux parties élastiques :

  • une première partie élastique formée par la branche élastique 36 reliant le deuxième organe réglant 30 à l'organe d'équilibrage 25,
  • et une deuxième partie élastique 55 reliant l'organe d'équilibrage 25 à l'organe de réglage de fréquence 53.
In the example shown in figure 3 , the elastic adjustment link 36, 55 comprises two elastic parts:
  • a first elastic part formed by the elastic branch 36 connecting the second regulating member 30 to the balancing member 25,
  • and a second elastic part 55 connecting the balancing member 25 to the frequency adjustment member 53.

La deuxième partie élastique 55 peut comporter au moins une partie en forme de U, ou être constituée par un U. Dans ce cas, la liaison élastique 55 peut comprendre deux branches sensiblement parallèles à l'axe Y qui sont reliées entre elles à une extrémité proche du cadre 15, et dont les extrémités libres sont reliées respectivement à l'organe de réglage de fréquence 53 et à l'organe d'équilibrage 25.The second elastic part 55 can comprise at least one U-shaped part, or be constituted by a U. In this case, the elastic connection 55 can comprise two branches substantially parallel to the Y axis which are connected together at one end. close to the frame 15, and the free ends of which are respectively connected to the frequency adjustment member 53 and to the balancing member 25.

L'organe de réglage de fréquence 53 est monté mobile par rapport au cadre 15 et à la platine de support 14a, au moins parallèlement à l'axe X, par exemple grâce aux branches élastiques 54 susmentionnées. L'organe de réglage de fréquence 53 comporte un dispositif de blocage 56 adapté pour bloquer l'organe de réglage de fréquence 53 par rapport à la platine de support 14a, et donc par rapport au cadre 15. Le dispositif de blocage peut comprendre par exemple une vis 56 vissée dans la platine de support 14a autour d'un axe 58.The frequency adjustment member 53 is mounted to move relative to the frame 15 and to the support plate 14a, at least parallel to the X axis, for example by virtue of the aforementioned elastic branches 54. The frequency adjustment member 53 comprises a locking device 56 suitable for locking the frequency adjustment member 53 relative to the support plate 14a, and therefore relative to the frame 15. The locking device can include for example a screw 56 screwed into the support plate 14a around an axis 58.

Plus spécifiquement, dans l'exemple considéré, comme illustré sur les figures 3 et 3A, l'organe de réglage de fréquence 53 peut être relié à la platine de support 14a par une liaison excentrique, qui peut comprendre par exemple une came excentrique 56c en forme de disque, traversée par la tige 56b de la vis 56, tandis que la tête 56a de la vis 56 vient en appui sur ladite came excentrique 56c pour la bloquer. La came excentrique 56c est centrée sur un axe 57 décalé par rapport l'axe 58 de la vis 56.More specifically, in the example considered, as illustrated on the figures 3 and 3A , the frequency adjustment member 53 can be connected to the support plate 14a by an eccentric connection, which can for example comprise an eccentric cam 56c in the form of a disc, through which the rod 56b of the screw 56 passes, while the head 56a of screw 56 comes to rest on said eccentric cam 56c to lock it. The eccentric cam 56c is centered on an axis 57 offset from the axis 58 of the screw 56.

Avantageusement, l'organe de réglage 53 et le cadre 15 (ou la platine de support 14a) comportent des index 60, 61 en regard adaptés pour apprécier visuellement la position de l'organe de réglage 53 par rapport au cadre 15. Dans l'exemple représenté, le cadre 15 comporte un bossage 59 comportant un bord rectiligne pourvu de plusieurs index en regard de l'organe de réglage de fréquence 53, et l'organe de réglage de fréquence 53 comporte une pointe 61 ou similaire en regard des index 60.Advantageously, the adjustment member 53 and the frame 15 (or the support plate 14a) comprise facing indexes 60, 61 adapted to visually assess the position of the adjustment member 53 relative to the frame 15. In the example shown, the frame 15 comprises a boss 59 comprising a rectilinear edge provided with several indexes facing the frequency adjustment member 53, and the frequency adjustment member 53 comprises a point 61 or the like facing the indexes 60 .

Sur la figure 3, la came excentrique 56c est dans la position où l'organe de réglage de fréquence 53 est le plus proche de l'ancre 11 et n'impose pas de précontrainte élastique sur l'organe d'équilibrage 25. La fréquence f du régulateur 12 est alors maximale.On the figure 3 , the eccentric cam 56c is in the position where the frequency adjustment member 53 is closest to the anchor 11 and does not impose an elastic preload on the balancing member 25. The frequency f of the regulator 12 is then maximum.

Le mécanisme précédemment décrit fonctionne selon le principe expliqué dans la demande de brevet européen N° 14197015 susmentionnée ( EP3032350 ). Dans l'explication qui suit de ce fonctionnement, on utilise les notions de haut / bas, droite / gauche pour clarifier la description au regard de l'orientation des dessins des figures 3 à 5, mais ces indications ne sont pas limitatives.The mechanism described above operates according to the principle explained in European patent application No. 14197015 aforementioned ( EP3032350 ). In the following explanation of this operation, the notions of top / bottom, right / left are used to clarify the description with regard to the orientation of the drawings of the figures 3 to 5 , but these indications are not limiting.

Dans la situation de la figure 3, l'ancre 11 est dans une position extrême « droite » imposée par la branche élastique de transmission 36 et l'organe de distribution d'énergie 10 vient de pivoter sous l'effet du dispositif de stockage d'énergie 8, et au cours de ce mouvement l'organe élastique monostable 11a a fléchi puis s'est relâché en transmettant son énergie mécanique dans le régulateur 12, comme expliqué dans la demande de brevet européen N° 14197015 susmentionnée. La dent 17 de l'organe de distribution d'énergie située vers la gauche sur la figure 3 est alors en butée contre l'organe d'arrêt 21 situé sur la gauche de l'ancre 11. Les branches élastiques 31 sont en position de repos.In the situation of figure 3 , the anchor 11 is in an extreme "right" position imposed by the elastic transmission branch 36 and the distribution member energy 10 has just pivoted under the effect of the energy storage device 8, and during this movement the monostable elastic member 11a has flexed and then relaxed, transmitting its mechanical energy into the regulator 12, as explained in European patent application No. 14197015 aforementioned. Tooth 17 of the energy distribution member located to the left on the figure 3 is then in abutment against the stop member 21 located on the left of the anchor 11. The elastic branches 31 are in the rest position.

Les premier et deuxième organes réglants 29, 30 oscillent selon la direction de translation O1 entre les deux positions extrêmes représentées respectivement sur les figures 4 et 5, avec une fréquence f pouvant être comprise par exemple entre 20 et 30 Hz.The first and second regulating members 29, 30 oscillate in the direction of translation O1 between the two extreme positions shown respectively on the figures 4 and 5 , with a frequency f which may for example be between 20 and 30 Hz.

Sur un demi-cycle de mouvement, par exemple lorsque le premier organe réglant 29 passe de la position extrême « haute » de la figure 4 à la position extrême « basse » de la figure 5, le deuxième organe réglant 30 passe de la position extrême « basse » de la figure 4 à la position extrême « haute » de la figure 5, du fait de la présence du levier d'équilibrage 37. Pendant ce temps, l'ancre 11 passe de la position extrême « gauche » de la figure 4 à la position extrême « droite » de la figure 3 au moment où les premier et deuxième organes réglants passent dans la position neutre de la figure 3, puis l'ancre 11 repart vers la gauche 5 jusqu'à la position extrême « gauche » de la figure 5, où l'organe de distribution d'énergie 10 échappe à nouveau et tourne d'un pas sous la sollicitation du dispositif de stockage d'énergie 8. Pendant ce temps, l'organe d'équilibrage 25 suit un mouvement symétrique et opposé à l'ancre 11.Over a half-cycle of movement, for example when the first regulating member 29 passes from the extreme "high" position of the figure 4 at the extreme "low" position of the figure 5 , the second regulating member 30 passes from the extreme "low" position of the figure 4 at the extreme "high" position of the figure 5 , due to the presence of the balancing lever 37. During this time, the anchor 11 moves from the extreme "left" position of the figure 4 to the extreme "right" position of the figure 3 when the first and second regulating organs pass into the neutral position of the figure 3 , then anchor 11 sets off again to the left 5 to the extreme "left" position of the figure 5 , where the energy distribution member 10 escapes again and rotates with one step under the stress of the energy storage device 8. During this time, the balancing member 25 follows a movement symmetrical and opposite to anchor 11.

L'ancre 11 et l'organe d'équilibrage 25 oscillent donc avec une fréquence 2f selon la direction de translation 02.The anchor 11 and the balancing member 25 therefore oscillate with a frequency 2f in the direction of translation 02.

Le fonctionnement est le même lorsqu'on passe ensuite de la position de la figure 5 à celle de la figure 4. Les étapes susmentionnées se répètent ensuite indéfiniment.The operation is the same when moving from the position of the figure 5 to that of figure 4 . The aforementioned steps are then repeated indefinitely.

Lorsqu'il est nécessaire de procéder à un réglage fin de la fréquence f du régulateur, par exemple au montage initial du mouvement 3 ou après un entretien, un opérateur peut desserrer la vis 56 et ajuster la position de l'organe de réglage de fréquence 53, manuellement ou par des moyens automatisés, jusqu'à obtention de la fréquence exacte souhaitée (mesurée par des moyens classiques, notamment optiques), éventuellement en se guidant avec les index 60, 61. Dans la position de la figure 6, l'organe de réglage de fréquence 53 est dans sa position extrême la plus éloignée de l'ancre 11 (c'est-à-dire la position la plus à droite sur la figure 6), de sorte que la deuxième partie élastique 55 impose une contrainte vers la droite sur l'organe d'équilibrage 25, modifiant ainsi la fréquence d'oscillation f du système.When it is necessary to fine-tune the frequency f of the regulator, for example during the initial assembly of movement 3 or after maintenance, an operator can loosen the screw 56 and adjust the position of the frequency adjuster. 53, manually or by automated means, until the exact desired frequency is obtained (measured by conventional means, in particular optical), possibly by being guided with the indexes 60, 61. In the position of the figure 6 , the frequency adjustment member 53 is in its extreme position furthest from the anchor 11 (that is to say the position furthest to the right on the figure 6 ), so that the second elastic part 55 imposes a stress to the right on the balancing member 25, thus modifying the oscillation frequency f of the system.

Dans la deuxième forme de réalisation de l'invention, représentée sur les figures 7 et 7A, les explications ci-dessus relatives aux figures 1 et 2 restent valables.In the second embodiment of the invention, shown in the figures 7 and 7A , the above explanations relating to figures 1 and 2 remain valid.

L'ancre 11 et le régulateur 12 forment un mécanisme 13 monolithique, formé dans une même plaque 14 (habituellement plane) et dont les pièces mobiles sont conçues pour se déplacer essentiellement dans un plan moyen de ladite plaque 14. Les explications relatives à la plaque 14 données au regard de la première forme de réalisation restent valables dans la deuxième forme de réalisation.The anchor 11 and the regulator 12 form a monolithic mechanism 13, formed in the same plate 14 (usually flat) and the moving parts of which are designed to move essentially in a mean plane of said plate 14. The explanations relating to the plate 14 data with regard to the first embodiment remain valid in the second embodiment.

La plaque 14 comporte un support 15 qui est solidarisé à une platine de support 14a, par exemple par des vis ou similaires (non représentées) traversant des trous 15a du support 15. La platine de support 14a est solidarisée au boîtier 2 de la pièce d'horlogerie 1.The plate 14 comprises a support 15 which is secured to a support plate 14a, for example by screws or the like (not shown) passing through holes 15a of the support 15. The support plate 14a is secured to the housing 2 of the part d 'watchmaking 1.

L'organe de distribution d'énergie 10 peut être une roue d'échappement montée rotative par exemple sur la platine de support 14a, de façon à pouvoir tourner autour d'un axe de rotation Z1 perpendiculaire au plan XY de la plaque 14. L'organe de distribution d'énergie 10 est sollicité par le dispositif de stockage d'énergie 8 dans un unique sens de rotation 16.The energy distribution member 10 can be an escape wheel mounted to rotate, for example on the support plate 14a, so as to be able to rotate about an axis of rotation Z1 perpendicular to the XY plane of the plate 14. L The energy distribution member 10 is requested by the energy storage device 8 in a single direction of rotation 16.

L'organe de distribution d'énergie 10 présente des dents externes 17.The energy distribution member 10 has external teeth 17.

L'organe réglant 118 du régulateur 12 est relié au support 15 par une suspension élastique 119 reliant ledit organe réglant au support. Plus spécifiquement, ledit organe réglant 118 peut présenter sensiblement une symétrie axiale d'ordre n par rapport à un axe central Z'0 orthogonal au plan moyen XY et fixe par rapport au support 15. Par « présente sensiblement une symétrie axiale d'ordre n », on entend que l'organe réglant 118 est pour l'essentiel conformé selon cette symétrie, mais que certaines parties de masse relativement négligeable peuvent ne pas présenter cette symétrie (par exemple des parties servant au couplage de l'ancre avec l'organe réglant).The regulating member 118 of the regulator 12 is connected to the support 15 by an elastic suspension 119 connecting said regulating member to the support. More specifically, said regulating member 118 may have substantially an axial symmetry of order n with respect to a central axis Z'0 orthogonal to the mean plane XY and fixed with respect to the support 15. By "has substantially an axial symmetry of order n ", It is understood that the regulating member 118 is essentially shaped according to this symmetry, but that certain parts of relatively negligible mass may not present this symmetry (for example parts serving for the coupling of the anchor with the member. regulating).

Ledit organe réglant 118 comprend un nombre n de portions rigides reliées entre elles deux à deux par n liaisons élastiques de couplage, n étant un nombre entier au moins égal à 2.Said regulating member 118 comprises a number n of rigid portions interconnected in pairs by n elastic coupling links, n being an integer at least equal to 2.

La suspension élastique 119 comprend n liaisons élastiques de suspension reliant respectivement chaque portion rigide de l'organe réglant au support 15.The elastic suspension 119 comprises n elastic suspension links respectively connecting each rigid portion of the regulating member to the support 15.

En particulier, la suspension élastique peut être prévue pour que l'organe réglant 118 soit mobile sensiblement en rotation autour de l'axe central Z'0.In particular, the elastic suspension can be provided so that the regulating member 118 is movable substantially in rotation about the central axis Z'0.

Le nombre n est avantageusement égal à 3 ; il peut toutefois être égal à 2 ou plus que 3. Lorsque le nombre n est de 3 ou plus, chaque portion rigide de l'organe réglant 118 est reliée à deux portions rigides adjacentes de l'organe réglant respectivement par deux liaisons élastiques de couplage.The number n is advantageously equal to 3; it may however be equal to 2 or more than 3. When the number n is 3 or more, each rigid portion of the regulating member 118 is connected to two adjacent rigid portions of the regulating member respectively by two elastic coupling links.

L'organe réglant 118 du régulateur 12 peut présenter une forme générale annulaire centrée sur l'axe central Z'0 et comprend 3 portions rigides 120 reliées entre elles deux à deux par 3 liaisons élastiques de couplage 121.The regulating member 118 of the regulator 12 may have a generally annular shape centered on the central axis Z'0 and comprises 3 rigid portions 120 interconnected in pairs by 3 elastic coupling links 121.

La suspension élastique 119 qui relie l'organe réglant 118 du régulateur 12 au support 15, comprend 3 liaisons élastiques de suspension 122 reliant respectivement chaque portion rigide 120 au support 15 de façon que chaque portion rigide 120 soit mobile selon un mouvement au moins de rotation autour de l'axe central Z'0, l'organe réglant 118 ayant un mouvement global sensiblement de rotation autour de l'axe central Z'0.The elastic suspension 119 which connects the regulating member 118 of the regulator 12 to the support 15, comprises 3 elastic suspension links 122 respectively connecting each rigid portion 120 to the support 15 so that each rigid portion 120 is movable according to at least one rotational movement. around the central axis Z'0, the regulating member 118 having a substantially rotational overall movement around the central axis Z'0.

Chaque liaison élastique de suspension 122 comprend avantageusement au moins une branche élastique 123, par exemple une branche élastique 123. Chaque branche élastique 123 peut éventuellement comporter un tronçon rigide 123a, par exemple vers le centre de ladite branche élastique 123.Each elastic suspension link 122 advantageously comprises at least one elastic branch 123, for example an elastic branch 123. Each elastic branch 123 may optionally include a rigid section 123a, for example towards the center of said elastic branch 123.

Du fait que les branches élastiques 123 fléchissent lors de la rotation de l'organe réglant, les portions rigides 120 de l'organe réglant sont mobiles à la fois en rotation et en translation radiale par rapport à l'axe central Z'0.Due to the fact that the elastic branches 123 flex during the rotation of the regulating member, the rigid portions 120 of the regulating member are movable both in rotation and in radial translation with respect to the central axis Z'0.

Le support 15 peut éventuellement présenter une forme sensiblement en étoile, avec trois branches 15b reliées par une partie centrale 15c proche de l'axe Z'0.The support 15 may optionally have a substantially star shape, with three branches 15b connected by a central part 15c close to the axis Z'0.

Les portions rigides 120 de l'organe réglant 118 peuvent comporter chacune une partie 124 en forme d'arc de cercle centré sur l'axe central Z'0. Les parties 124 en forme d'arc de cercle sont voisines les unes des autres et forment ensemble un anneau discontinu centré sur l'axe central Z'0.The rigid portions 120 of the regulating member 118 may each include a portion 124 in the form of an arc of a circle centered on the central axis Z'0. The parts 124 in the form of a circular arc are adjacent to each other and together form a discontinuous ring centered on the central axis Z'0.

Chaque branche élastique 123 peut s'étendre sensiblement radialement par rapport à l'axe central Z'0 et relier la partie 124 en forme d'arc de cercle d'une des portions rigides 120, à la partie centrale 15c susmentionnée du support 15.Each elastic branch 123 can extend substantially radially with respect to the central axis Z'0 and connect the part 124 in the form of an arc of a circle of one of the rigid portions 120, to the aforementioned central part 15c of the support 15.

Les parties 124 en forme d'arc de cercle s'étendent chacune angulairement entre une première extrémité 125 et une deuxième extrémité 126 qui se recouvrent mutuellement en direction angulaire. Par exemple, chaque première extrémité 125 peut former un premier doigt 125a s'étendant vers la portion rigide 120 adjacente et chaque deuxième extrémité 126 peut former un deuxième doigt 126a s'étendant vers la portion rigide 120 adjacente, chaque premier doigt 125a recouvrant vers l'extérieur le deuxième doigt 126a de la portion rigide 120 adjacente.The circular arc-shaped portions 124 each extend angularly between a first end 125 and a second end 126 which overlap each other in an angular direction. For example, each first end 125 may form a first finger 125a extending toward the adjacent rigid portion 120 and each second end 126 may form a second finger 126a extending toward the adjacent rigid portion 120, each first finger 125a overlapping toward the end. 'outside the second finger 126a of the adjacent rigid portion 120.

La deuxième extrémité 126 de chaque partie 124 en forme d'arc de cercle peut être prolongée sensiblement radialement vers l'intérieur par un bras rigide 127 terminé par un bec 128 s'étendant angulairement au-delà de la deuxième extrémité, en direction de la portion rigide 120 adjacente.The second end 126 of each part 124 in the form of an arc of a circle can be extended substantially radially inwards by a rigid arm 127 terminated by a spout 128 extending angularly beyond the second end, in the direction of the adjacent rigid portion 120.

Chaque liaison élastique de couplage 121 peut comporter au moins une branche élastique de couplage 121a (ici 2 branches élastiques de couplage 121a parallèles) s'étendant sensiblement radialement par rapport à l'axe central Z'0 et reliant le bec 128 de chaque portion rigide 120 à la première extrémité 125 de la partie 124 en arc de cercle de la portion rigide 120 adjacente.Each elastic coupling link 121 can comprise at least one elastic coupling branch 121a (here 2 elastic coupling branches 121a parallel) extending substantially radially with respect to the central axis Z'0 and connecting the spout 128 of each rigid portion 120 at the first end 125 of the circular arc portion 124 of the adjacent rigid portion 120.

Les débattements de chaque portion rigide 120 de l'organe réglant peuvent être limités par des moyens de limitation de mouvement par rapport au support 15, pour limiter les débattements notamment angulaires des portions rigides 120 et protéger le mécanisme 13 notamment en cas de choc ou plus généralement lorsqu'il subit de fortes accélérations.The deflections of each rigid portion 120 of the regulating member can be limited by means for limiting movement relative to the support 15, in order to limit the displacements, in particular angular, of the rigid portions 120 and to protect the mechanism 13, in particular in the event of an impact or more. usually when it undergoes strong accelerations.

Ces moyens de limitation de mouvement peuvent comporter une fente 129 ménagée dans chaque partie 124 en arc de cercle et s'étendant angulairement autour de l'axe central Z'0, et un pion 130 qui est solidaire du support 15 (en fait, fixé à la platine de support 14a) et qui est disposé dans la fente 129. Les fentes 129 sont conformées selon la cinématique des portions rigides 120 lors du mouvement de rotation de l'organe réglant 118. Les fentes 129 ne sont donc pas de forme circulaire centrée sur l'axe central Z'0, mais ici plutôt en forme de tronçons de spirales.These movement limitation means can comprise a slot 129 formed in each part 124 in an arc of a circle and extending angularly around the central axis Z'0, and a pin 130 which is integral with the support 15 (in fact, fixed to the support plate 14a) and which is disposed in the slot 129. The slots 129 are shaped according to the kinematics of the rigid portions 120 during the rotational movement of the regulating member 118. The slots 129 are therefore not circular in shape centered on the central axis Z '0, but here rather in the form of sections of spirals.

L'ancre 11 et l'organe de distribution d'énergie 10 peuvent être disposés à l'intérieur de l'organe réglant 118.The anchor 11 and the energy distribution member 10 can be placed inside the regulating member 118.

L'ancre 11 est une pièce rigide qui peut comporter un corps rigide 131 voisin de la partie 124 en arc de cercle d'une des portions rigides 120 de l'organe réglant. L'ancre 11 peut comporter en outre un bras rigide d'entraînement 132 qui est solidaire du corps rigide 131 et qui s'étend vers l'une des branches 15b du support à partir dudit corps rigide 131.The anchor 11 is a rigid part which may include a rigid body 131 adjacent to the part 124 in the arc of a circle of one of the rigid portions 120 of the regulating member. The anchor 11 may further include a rigid drive arm 132 which is integral with the rigid body 131 and which extends towards one of the branches 15b of the support from said rigid body 131.

L'ancre 11 est reliée élastiquement au support 15, de façon à pouvoir osciller, par exemple selon un mouvement sensiblement en rotation autour d'un axe Z2 perpendiculaire au plan XY. Les oscillations de l'ancre 11 sont commandées par l'organe réglant 118.The anchor 11 is elastically connected to the support 15, so as to be able to oscillate, for example according to a substantially rotational movement about an axis Z2 perpendicular to the XY plane. The oscillations of the anchor 11 are controlled by the regulating member 118.

A cet effet, le bras rigide 127 d'une des portions rigides 120 de l'organe réglant peut être prolongé vers l'intérieur par un bras rigide supplémentaire 133 dont l'extrémité libre est reliée à l'extrémité libre du bras rigide d'entraînement 132 par une branche élastique d'entraînement 134.For this purpose, the rigid arm 127 of one of the rigid portions 120 of the regulating member can be extended inwards by an additional rigid arm 133, the free end of which is connected to the free end of the rigid arm of drive 132 by an elastic drive branch 134.

Avantageusement, l'ancre 11 peut être reliée au support 15 par une suspension élastique, comprenant par exemple deux branches élastiques 135 de suspension d'ancre convergeant sensiblement vers l'axe Z2. Eventuellement, les branches élastiques 135 peuvent relier le corps rigide 131 à l'extrémité libre 15d d'une des branches 15b du support.Advantageously, the anchor 11 can be connected to the support 15 by an elastic suspension, comprising for example two elastic anchor suspension branches 135 converging substantially towards the axis Z2. Eventually, the elastic branches 135 can connect the rigid body 131 to the free end 15d of one of the branches 15b of the support.

L'ancre 11 comporte deux organes d'arrêt 136, 137 en forme d'ergots faisant saillie sensiblement vers l'axe Z1, qui sont adaptés pour coopérer avec l'organe de distribution d'énergie 10.The anchor 11 comprises two stop members 136, 137 in the form of lugs projecting substantially towards the axis Z1, which are adapted to cooperate with the energy distribution member 10.

L'ancre 11 est ainsi commandée par ledit organe réglant 118 pour régulièrement et alternativement bloquer et libérer l'organe de distribution d'énergie 10 à l'aide des organes d'arrêt 136, 137, de sorte que ledit organe de distribution d'énergie 10 se déplace pas à pas dans la direction 16 sous la sollicitation du dispositif de stockage d'énergie 8 selon un cycle de mouvement répétitif, et ladite ancre 11 est en outre adaptée pour transférer de l'énergie mécanique à l'organe réglant 118 au cours de ce cycle de mouvement répétitif, de façon connue en soi.The anchor 11 is thus controlled by said regulating member 118 to regularly and alternately block and release the energy distribution member 10 by means of the stop members 136, 137, so that said distribution member energy 10 moves step by step in the direction 16 under the stress of the energy storage device 8 in a repetitive motion cycle, and said anchor 11 is further adapted to transfer mechanical energy to the regulating member 118 during this repetitive movement cycle, in a manner known per se.

Dans un exemple de réalisation, la masse totale des parties oscillantes du mécanisme peut être d'environ 0,33 g et leur inertie d'environ 20,19 10-9 kg.m2, la fréquence d'oscillation de l'organe réglant 118 est d'environ 18 Hz et la raideur en rotation du mécanisme est d'environ 2,58 10-4 Nm/rad. Un tel mécanisme présente un très bon isochronisme, qui conduit à une très bonne précision temporelle.In an exemplary embodiment, the total mass of the oscillating parts of the mechanism can be approximately 0.33 g and their inertia approximately 20.19 10 -9 kg.m 2 , the frequency of oscillation of the regulating member. 118 is about 18 Hz and the rotational stiffness of the mechanism is about 2.58 10 -4 Nm / rad. Such a mechanism exhibits very good isochronism, which leads to very good temporal precision.

Le mécanisme 13 comporte en outre un dispositif de réglage de fréquence permettant de régler la fréquence f susmentionnée. Ce dispositif de réglage de fréquence comprend un organe de réglage de fréquence 153 rigide, qui permet d'effectuer un réglage fin de la fréquence d'oscillation du régulateur 12, notamment lors du montage du mouvement 3. L'organe de réglage de fréquence 153 peut par exemple être formé d'une seule pièce dans la plaque 14 avec les autres éléments du mécanisme 13 susmentionné.The mechanism 13 further comprises a frequency adjustment device making it possible to adjust the aforementioned frequency f. This frequency adjustment device comprises a rigid frequency adjustment member 153, which makes it possible to perform a fine adjustment of the oscillation frequency of the regulator 12, in particular during the assembly of the movement 3. The frequency adjustment member 153 can for example be formed integrally in the plate 14 with the other elements of the aforementioned mechanism 13.

L'organe de réglage de fréquence 153 est relié, directement ou indirectement, à au moins une des portions rigides 120 de l'organe réglant 118 par une liaison élastique dite de réglage 155. L'organe de réglage de fréquence 153 est en outre réglable en position par rapport à la platine de support 14a et au support 15 de façon à pouvoir déformer la liaison élastique de réglage 155 et appliquer ainsi une contrainte élastique réglable sur l'organe réglant 118, de façon à influer sur la raideur globale de la suspension élastique du régulateur 12, et donc sur la fréquence f susmentionnée.The frequency adjustment member 153 is connected, directly or indirectly, to at least one of the portions rigid 120 of the regulating member 118 by a so-called adjusting elastic link 155. The frequency adjustment member 153 is also adjustable in position with respect to the support plate 14a and to the support 15 so as to be able to deform the link elastic adjustment 155 and thus apply an adjustable elastic stress on the adjusting member 118, so as to influence the overall stiffness of the elastic suspension of the regulator 12, and therefore on the above-mentioned frequency f.

L'organe de réglage de fréquence 153 peut présenter une forme allongée s'étendant entre une première extrémité 153a et une deuxième extrémité 153b. L'organe de réglage de fréquence 153 peut être disposé à l'intérieur de l'organe réglant 118, par exemple entre une des branches 15b du support 15 et un des bras rigides 127 susmentionnés. La deuxième extrémité 153b peut éventuellement être en forme de fourche ou comporter un trou de passage pour une vis de réglage 156. La deuxième extrémité 153b peut éventuellement être disposée en regard d'une partie échancrée 15e de la branche 15b adjacente du support.The frequency adjustment member 153 may have an elongated shape extending between a first end 153a and a second end 153b. The frequency adjustment member 153 can be placed inside the adjustment member 118, for example between one of the branches 15b of the support 15 and one of the rigid arms 127 mentioned above. The second end 153b may optionally be in the form of a fork or include a passage hole for an adjusting screw 156. The second end 153b may optionally be placed opposite a notched portion 15e of the adjacent branch 15b of the support.

L'organe de réglage de fréquence 153 peut par exemple être relié à l'un des branches 15b du support 15 par deux branches élastiques 154. Les branches élastiques 154 peuvent converger vers la première extrémité 153a, qui définit ainsi un axe de pivotement Z3 de l'organe de réglage de fréquence 153 (perpendiculaire au plan XY susmentionné). La partie échancrée 15e de la branche 15b adjacente à l'organe de réglage de fréquence 153 peut avantageusement présenter un bord 15f sensiblement circulaire et centré sur l'axe de pivotement Z3, qui peut éventuellement être sensiblement au contact de la deuxième extrémité 153b de l'organe de réglage de fréquence 153 et ainsi contribuer à guider l'organe de réglage de fréquence 153 lorsqu'il est réglé en position. La partie échancrée 15e de la branche 15b en question peut éventuellement comporter des index 60 tels que décrits dans la première forme de réalisation.The frequency adjustment member 153 can for example be connected to one of the branches 15b of the support 15 by two elastic branches 154. The elastic branches 154 can converge towards the first end 153a, which thus defines a pivot axis Z3 of the frequency regulator 153 (perpendicular to the aforementioned XY plane). The notched portion 15e of the branch 15b adjacent to the frequency adjustment member 153 may advantageously have an edge 15f which is substantially circular and centered on the pivot axis Z3, which may optionally be substantially in contact with the second end 153b of the frequency adjuster 153 and thus help guide the frequency adjuster 153 when it is adjusted in position. The notched part 15e of the branch 15b in question may possibly include indexes 60 as described in the first embodiment.

Dans l'exemple représenté sur les figures 7 et 7A, l'organe de réglage de fréquence 153 comporte un bras de levier 153c qui prolonge la première extrémité 153a à l'opposé de la deuxième extrémité 153b. Ce bras de levier 153c peut s'étendre avec un certain angle par rapport au corps principal de l'organe de réglage de fréquence 153 (c'est-à-dire la partie comprise entre les première et deuxième extrémités 153a, 153b), par exemple un angle d'environ 90 degrés. Le bras de levier 153c est avantageusement plus court que le corps principal de l'organe de réglage de fréquence 153, par exemple 3 à 6 fois plus court, ce qui permet qu'un mouvement de la première extrémité 153a induise un relativement plus faible mouvement de l'extrémité libre du bras de levier 153c.In the example shown on figures 7 and 7A , the frequency adjustment member 153 comprises a lever arm 153c which extends the first end 153a opposite the second end 153b. This lever arm 153c can extend at an angle relative to the main body of the frequency adjuster 153 (i.e. the part between the first and second ends 153a, 153b), for example example an angle of about 90 degrees. The lever arm 153c is advantageously shorter than the main body of the frequency adjustment member 153, for example 3 to 6 times shorter, which allows a movement of the first end 153a to induce a relatively smaller movement. of the free end of the lever arm 153c.

La liaison élastique de réglage 155 peut relier l'extrémité libre du bras de levier 153c à l'organe réglant 118, par exemple à l'extrémité libre du bras rigide 127 adjacent à l'organe de réglage de fréquence 153.The elastic adjustment link 155 can connect the free end of the lever arm 153c to the adjusting member 118, for example to the free end of the rigid arm 127 adjacent to the frequency adjustment member 153.

Dans l'exemple représenté, cette liaison élastique de réglage 155 peut comporter trois branche élastiques 155a, 155b, 155c, comprenant une première branche élastique 155a partant de l'extrémité libre du bras de levier 153c et s'étendant jusqu'à un premier coude, la deuxième branche élastique 155b s'étendant du premier coude à un deuxième coude et la troisième branche élastique 155c s'étendant du troisième coude à l'extrémité libre du bras rigide 127 susmentionné.In the example shown, this elastic adjustment link 155 may include three elastic branches 155a, 155b, 155c, comprising a first elastic branch 155a starting from the free end of the lever arm 153c and extending to a first elbow. , the second elastic branch 155b extending from the first elbow to a second elbow and the third elastic branch 155c extending from the third elbow to the free end of the aforementioned rigid arm 127.

L'organe de réglage de fréquence 153 peut être réglé par pivotement de sa deuxième extrémité 153b autour de l'axe de pivotement Z3 puis maintenu en position par la vis de réglage 156 susmentionnée. La vis de réglage 156 peut par exemple traverser une fente 161 en arc de cercle ménagée dans la platine de support 14a. Cette fente peut présenter une forme sensiblement en arc de cercle centré sur l'axe de pivotement Z3. La vis de réglage 156 peut par exemple être vissée dans un écrou (non représenté) disposé sous la platine de support 14a. Le réglage et le maintien en position de l'organe de réglage de fréquence 153 pourrait être fait par tout autre moyen tels que liaison excentrique ou autre.The frequency adjustment member 153 can be adjusted by pivoting its second end 153b around the pivot axis Z3 and then held in position by the aforementioned adjustment screw 156. The adjustment screw 156 may for example pass through a slot 161 in the form of an arc of a circle formed in the support plate 14a. This slot can have a substantially circular arc shape centered on the pivot axis Z3. The adjustment screw 156 can for example be screwed into a nut (not shown) arranged under the support plate 14a. The adjustment and maintenance in position of the frequency adjustment member 153 could be done by any other means such as an eccentric connection or the like.

Lorsqu'il est nécessaire de procéder à un réglage fin de la fréquence f du régulateur, par exemple au montage initial du mouvement 3 ou après un entretien, un opérateur peut desserrer la vis de réglage 156 et ajuster la position de l'organe de réglage de fréquence 153, manuellement ou par des moyens automatisés, jusqu'à obtention de la fréquence exacte souhaitée (mesurée par des moyens classiques, notamment optiques).When it is necessary to fine-tune the frequency f of the regulator, for example during the initial assembly of movement 3 or after maintenance, an operator can loosen the adjusting screw 156 and adjust the position of the regulator. frequency 153, manually or by automated means, until the exact desired frequency is obtained (measured by conventional means, in particular optical).
