Description

La présente invention se rapporte aux mécanismes d'échappement pour mouvement d'horlogerie.The present invention relates to escapement mechanisms for a watch movement.

Dans un mouvement pour pièce d'horlogerie, l'échappement a pour but d'entretenir et de compter les oscillations de l'organe réglant dudit mouvement, comme par exemple un balancier-spiral. L'échappement reçoit l'énergie dispensée par le barillet du mouvement pour pièce d'horlogerie et laisse échapper périodiquement un fragment de cette énergie pour restituer à l'organe réglant l'énergie qu'il perd dû aux frottements. Il est important que l'échappement perturbe le moins possible l'organe régulateur.In a movement for a timepiece, the purpose of the escapement is to maintain and count the oscillations of the regulating member of said movement, such as for example a balance-spring. The escapement receives the energy dispensed by the barrel of the timepiece movement and periodically lets out a fragment of this energy to restore to the regulating organ the energy it loses due to friction. It is important that the exhaust disturbs the regulating organ as little as possible.

Cependant, le rendement mécanique des échappements est typiquement faible puisque celui qui est généralement considéré comme le meilleur d'entre eux, l'échappement à ancre suisse, ne transmet à l'organe réglant que 30% environ de l'énergie qu'il reçoit. Cela est dû notamment à l'inertie des pièces qu'il faut mettre en mouvement rapidement, aux frottements, aux chocs et à la présence nécessaire de chemins perdus (courses mortes). CH 698 435 B1 dévoile une pièce d'horlogerie ayant un organe moteur, un dispositif régulateur avec un balancier-spiral et un dispositif de force constante. Le barillet transmet une force motrice au dispositif de force constante comprenant un ressort auxiliaire, qui lui-même transmet des impulsions d'énergie constante au dispositif régulateur, indépendamment de la tension du ressort du barillet.However, the mechanical efficiency of exhausts is typically low since the one which is generally considered to be the best of them, the Swiss anchor escapement, transmits to the regulating organ only around 30% of the energy it receives. . This is due in particular to the inertia of the parts which must be put into motion quickly, to friction, to shocks and to the necessary presence of lost paths (dead strokes). CH 698 435 B1 unveils a timepiece having a driving organ, a regulating device with a balance-spring and a constant force device. The barrel transmits a driving force to the constant force device comprising an auxiliary spring, which itself transmits pulses of constant energy to the regulating device, independently of the tension of the spring of the barrel.

Le but de la présente invention est de réaliser un mouvement pour pièce d'horlogerie comprenant un mécanisme d'échappement dans lequel l'inertie des pièces en mouvement lors de l'impulsion est très faible et dans lequel la grande majorité voire la totalité de la course angulaire de l'organe d'impulsion est active, supprimant ainsi les courses mortes. Un autre but de la présente invention est de réaliser un mouvement pour pièce d'horlogerie dans lequel le rendement du mécanisme d'échappement est nettement amélioré de même que la précision de la chronométrie du mouvement.The object of the present invention is to produce a movement for a timepiece comprising an escapement mechanism in which the inertia of the moving parts during the impulse is very low and in which the vast majority or even all of the angular stroke of the impulse member is active, thereby eliminating dead strokes. Another object of the present invention is to provide a movement for a timepiece in which the efficiency of the escapement mechanism is significantly improved as is the precision of the timing of the movement.

La présente invention a pour objet un mouvement d'horlogerie comportant un mobile d'échappement relié à un barillet par un rouage de finissage et un balancier-spiral ainsi qu'un mécanisme d'échappement comprenant une ancre d'impulsion et au moins un organe de réglage caractérisé par le fait que l'ancre d'impulsion et l'organe de réglage sont commandés par des organes de commande portés par l'axe du balancier ; par le fait que l'ancre d'impulsion et l'organe de réglage coopèrent avec le mobile d'échappement ; et par le fait que l'ancre d'impulsion et l'organe de réglage se déplacent dans deux plans formant un angle entre eux.The present invention relates to a timepiece movement comprising an escapement mobile connected to a barrel by a gear train and a balance-spring as well as an escapement mechanism comprising an anchor impulse and at least one adjustment member characterized in that the impulse anchor and the adjustment member are controlled by control members carried by the pendulum axis; by the fact that the pulse anchor and the adjustment member cooperate with the exhaust mobile; and by the fact that the pulse anchor and the adjusting member move in two planes forming an angle between them.

Dans la suite, les orientations et en particulier les sens de rotation sont données en référence aux figures.In the following, the orientations and in particular the directions of rotation are given with reference to the figures.

Une première forme d'exécution d'un échappement pour mouvement d'horlogerie selon l'invention va être décrite en référence aux figures 1 à 8.A first embodiment of an escapement for a watch movement according to the invention will be described with reference to figures 1 to 8 .

Selon cette forme d'exécution, le mécanisme d'échappement est destiné à équiper un mouvement d'horlogerie comprenant un balancier-spiral et un mobile d'échappement relié à un barillet par un rouage de finissage. Ce mécanisme d'échappement est dans cette forme d'exécution un mécanisme d'échappement à force constante et comporte une ancre d'impulsion coopérant d'une part avec le mobile d'échappement et d'autre part avec des organes de commande solidaires de l'arbre du balancier-spiral.According to this embodiment, the escapement mechanism is intended to equip a timepiece movement comprising a balance-spring and an escapement mobile connected to a barrel by a gear train. This exhaust mechanism is in this embodiment a constant force exhaust mechanism and comprises a pulse anchor cooperating on the one hand with the exhaust mobile and on the other hand with control members integral with the balance-spring shaft.

Dans cette première forme d'exécution, le mécanisme d'échappement comporte un mobile d'échappement 1 comportant, monté sur un axe 1.1, un pignon d'échappement 1.2 relié cinématiquement par un rouage de finissage (non illustré) au barillet (non illustré) d'un mouvement d'horlogerie.In this first embodiment, the exhaust mechanism comprises an exhaust mobile 1 comprising, mounted on an axis 1.1, an exhaust pinion 1.2 kinematically connected by a gear train (not illustrated) to the barrel (not illustrated ) a watch movement.

Ce mobile d'échappement 1 comporte encore une roue d'échappement inférieure 1.3, une roue d'échappement intermédiaire 1.4 et une roue d'échappement supérieure 1.5 toutes trois solidaires de l'axe 1.1. Ce mobile d'échappement 1 est pivoté sur une partie du bâti du mouvement d'horlogerie telle que la platine, un pont, ou une cage de tourbillon de ce mouvement d'horlogerie.This exhaust mobile 1 also comprises a lower escape wheel 1.3, an intermediate escape wheel 1.4 and an upper escape wheel 1.5 all three secured to the axis 1.1. This escapement mobile 1 is pivoted on a part of the frame of the timepiece movement such as the plate, a bridge, or a tourbillon cage of this timepiece movement.

Ce mécanisme d'échappement comporte encore des organes de commande solidaires de l'axe 2 du balancier-spiral (non illustré) pivoté sur une partie du bâti du mouvement d'horlogerie. Dans cette forme d'exécution, cet axe 2 du balancier-spiral, comporte un plateau de dard 3 muni d'une entaille 3.1; un plateau de cheville 4 comportant une cheville 4.1 situé sous le plateau de dard 3; un plateau de commande supérieur 6 comportant une came supérieure 6.1 sur sa face inférieure ; un plateau de commande inférieur 7 comportant une came inférieure 7.1 sur sa face supérieure faisant face audit plateau de commande supérieur 6 ; et un plateau d'impulsion 5 comportant un doigt d'impulsion 5.1 et situé entre les plateaux de commande supérieur 6 et inférieur 7. Ces différents plateaux et les éléments qu'ils portent ou comprennent constituent un ensemble d'organes de commande du mécanisme d'échappement comme cela sera expliqué dans ce qui suit.This escapement mechanism also includes control members integral with the axis 2 of the balance-spring (not shown) pivoted on a part of the frame of the watch movement. In this embodiment, this axis 2 of the sprung balance comprises a dart plate 3 provided with a notch 3.1; an ankle plate 4 comprising a pin 4.1 located under the dart plate 3; an upper control plate 6 comprising an upper cam 6.1 on its lower face; a lower control plate 7 comprising a lower cam 7.1 on its upper face facing said upper control plate 6; and an impulse plate 5 comprising an impulse finger 5.1 and situated between the upper 6 and lower 7 control plates. These various plates and the elements which they carry or comprise constitute a set of control members of the mechanism d exhaust as will be explained in the following.

Le mécanisme d'échappement comporte encore une ancre d'impulsion 8 montée pivotante et coulissante longitudinalement sur une partie du bâti du mouvement d'horlogerie. L'ancre 8 est solidaire d'un axe de blocage 9, perpendiculaire au plan dans lequel l'ancre d'impulsion 8 pivote. Cet axe de blocage 9 s'étend de préférence parallèlement à l'axe 2 du balancier-spiral et à l'axe de rotation 1.1 du mobile d'échappement 1. Cet axe de blocage 9 est solidaire d'une virole 10 elle-même solidaire de l'extrémité intérieure d'un ressort auxiliaire de force constante 11, de préférence un ressort-spiral, dont l'extrémité extérieure 11.1 est prévue pour être fixée sur une partie du bâti du mouvement d'horlogerie.The escapement mechanism also includes a pulse anchor 8 pivotally mounted and sliding longitudinally on part of the frame of the watch movement. The anchor 8 is integral with a locking pin 9, perpendicular to the plane in which the pulse anchor 8 pivots. This blocking axis 9 preferably extends parallel to the axis 2 of the balance spring and the axis of rotation 1.1 of the escapement mobile 1. This blocking axis 9 is integral with a ferrule 10 itself secured to the inner end of a spring constant force auxiliary 11, preferably a balance spring, the outer end 11.1 of which is intended to be fixed to a part of the frame of the clockwork movement.

L'ancre d'impulsion 8 comporte une première extrémité 8.1 en forme de dent destinée à coopérer avec les dents d'une denture d'impulsion de la roue d'échappement inférieure 1.3. Cette ancre d'impulsion 8 comporte une seconde extrémité 8.2 s'étendant entre le plateau de commande supérieur 6 et le plateau de commande inférieur 7 solidaires de l'axe du balancier-spiral et destinée à coopérer avec les cames supérieure 6.1 et inférieure 7.1. Une première goupille 12, fixée sur une partie du bâti du mouvement d'horlogerie sert de butée d'arrêt à l'ancre d'impulsion 8. Le ressort auxiliaire 11 tend à déplacer l'ancre d'impulsion 8 en direction d'une seconde goupille 13.The pulse anchor 8 has a first tooth-shaped end 8.1 intended to cooperate with the teeth of a pulse toothing of the lower escape wheel 1.3. This pulse anchor 8 has a second end 8.2 extending between the upper control plate 6 and the lower control plate 7 secured to the axis of the balance spring and intended to cooperate with the upper 6.1 and lower 7.1 cams. A first pin 12, fixed on a part of the frame of the clockwork movement serves as a stop for the pulse anchor 8. The auxiliary spring 11 tends to move the pulse anchor 8 towards a second pin 13.

L'axe de blocage 9 portant l'ancre d'impulsion 8 est susceptible- d'être déplacé longitudinalement entre une position haute pour laquelle son extrémité de blocage 9.1 coopère avec une première denture de blocage de la roue d'échappement supérieure 1.5 et empêche toute rotation de celle-ci, et une position basse pour laquelle la roue d'échappement supérieure 1.5 est libérée de l'extrémité de blocage 9.1 de cet axe de blocage 9.The locking pin 9 carrying the pulse anchor 8 is capable of being displaced longitudinally between a high position for which its locking end 9.1 cooperates with a first locking gear of the upper escape wheel 1.5 and prevents any rotation thereof, and a low position for which the upper escape wheel 1.5 is released from the locking end 9.1 of this locking axis 9.

Le mécanisme d'échappement comporte encore une ancre de blocage 14 comportant quatre bras solidaires d'un axe d'ancre de blocage 14.1 pivoté sur une partie du bâti du mouvement d'horlogerie. Cette ancre de blocage 14 comporte un premier bras 14.2 coopérant avec une troisième goupille 15 et une quatrième goupille 16 pour limiter l'ébat angulaire de l'ancre de blocage 14.The escape mechanism also comprises a blocking anchor 14 comprising four arms secured to a blocking anchor axis 14.1 pivoted on a part of the frame of the clockwork movement. This blocking anchor 14 comprises a first arm 14.2 cooperating with a third pin 15 and a fourth pin 16 to limit the angular clearance of the blocking anchor 14.

L'ancre de blocage 14 comporte encore un second bras 14.3 dont l'extrémité comporte une fourchette 14.4 et un dard 14.5 destiné à coopérer avec la cheville 4.1 respectivement le plateau de dard 3 à l'instar d'un échappement à ancre suisse classique pour commander les déplacements angulaires de l'ancre de blocage 14. Cette ancre de blocage 14 comporte encore un troisième bras 14.6 dont l'extrémité libre sert de butée de maintien pour l'ancre d'impulsion 8 en position armée contre la première goupille 12.The blocking anchor 14 also has a second arm 14.3, the end of which includes a fork 14.4 and a dart 14.5 intended to cooperate with the dowel 4.1 respectively the dart plate 3 like a classic Swiss anchor escapement for controlling the angular displacements of the blocking anchor 14. This blocking anchor 14 also has a third arm 14.6 the free end of which serves as a holding stop for the pulse anchor 8 in the armed position against the first pin 12.

Enfin, cette ancre de blocage 14 comporte un quatrième bras 14.7 dont l'extrémité présente un crochet 14.8 destiné à coopérer avec une seconde denture de blocage de la roue d'échappement intermédiaire 1.4.Finally, this blocking anchor 14 comprises a fourth arm 14.7, the end of which has a hook 14.8 intended to cooperate with a second toothing for blocking the intermediate escape wheel 1.4.

Partant de la position initiale de ce mécanisme d'échappement selon la première forme d'exécution illustrée aux figures 2, 2a, on va dans ce qui suit décrire le fonctionnement de ce mécanisme. Le ressort auxiliaire 11 n'est pas illustré dans les figures 2 à 8 afin de ne pas les surcharger.Starting from the initial position of this escape mechanism according to the first embodiment illustrated in figures 2 , 2a , we will describe in the following how this mechanism works. The auxiliary spring 11 is not illustrated in the figures 2 to 8 so as not to overload them.

Dans la position initiale illustrée aux figures 2, 2a, le mobile d'échappement 1 est bloqué par l'extrémité 9.1 de l'axe de blocage 9 qui est en position haute. L'ancre d'impulsion 8 est également en position haute pour laquelle sa première extrémité 8.1 est située au-dessus du plan de la roue d'échappement inférieure 1.3 avec laquelle elle ne coopère donc pas.In the initial position illustrated in figures 2 , 2a , the exhaust mobile 1 is blocked by the end 9.1 of the locking pin 9 which is in the high position. The pulse anchor 8 is also in the high position for which its first end 8.1 is located above the plane of the lower escape wheel 1.3 with which it therefore does not cooperate.

L'ancre d'impulsion 8 est soumise à l'action du couple du ressort auxiliaire 11 qui tend à la faire tourner dans le sens horaire (selon les figures). L'ancre d'impulsion 8 est bloquée par l'extrémité du troisième bras 14.6 de l'ancre de blocage. L'ancre d'impulsion 8 soumise à l'action du ressort auxiliaire 11 pousse sur l'extrémité du troisième bras 14.6 de l'ancre de blocage 14, ce qui maintient celle-ci en appui contre la troisième goupille 15 par son second bras 14.2. Le dard 14.5 et le plateau de dard 3 évitent tout déblocage intempestif du mécanisme.The pulse anchor 8 is subjected to the action of the torque of the auxiliary spring 11 which tends to make it rotate clockwise (according to the figures). The pulse anchor 8 is blocked by the end of the third arm 14.6 of the blocking anchor. The pulse anchor 8 subjected to the action of the auxiliary spring 11 pushes on the end of the third arm 14.6 of the locking anchor 14, which keeps the latter in abutment against the third pin 15 by its second arm 14.2. The dart 14.5 and the dart plate 3 prevent any untimely unlocking of the mechanism.

Le balancier tourne dans le sens anti-horaire amenant la cheville 4.1 du plateau de cheville 4 dans la fourchette 14.4 de l'ancre de blocage 14 provoquant le déplacement de cette ancre de blocage dans le sens horaire jusqu'à ce que son second bras 14.2 bute contre la quatrième goupille 16 (Figures 3, 4). L'ancre d'impulsion 8 est libérée mais le mobile d'échappement 1 est toujours bloqué par l'axe de blocage 9.The pendulum rotates counterclockwise bringing the pin 4.1 of the pin plate 4 into the fork 14.4 of the blocking anchor 14 causing this blocking anchor to move clockwise until its second arm 14.2 abuts the fourth pin 16 ( Figures 3 , 4 ). The pulse anchor 8 is released but the exhaust mobile 1 is still blocked by the locking pin 9.

L'ancre d'impulsion 8 libérée se déplace dans le sens horaire sous l'effet du ressort auxiliaire 11. La seconde extrémité 8.2 de l'ancre d'impulsion se trouvant à la hauteur du plateau d'impulsion 5 entre en contact avec le doigt d'impulsion 5.1 et transmet l'énergie au balancier et ceci jusqu'à l'arrivée de l'ancre d'impulsion 8 contre la seconde goupille 13. Ainsi la transmission d'énergie se fait jusqu'à l'arrêt de l'ancre d'impulsion 8, il n'y a donc pas de course perdue de l'ancre d'impulsion.The released pulse anchor 8 moves clockwise under the effect of the auxiliary spring 11. The second end 8.2 of the pulse anchor located at the height of the impulse plate 5 comes into contact with the impulse finger 5.1 and transmits energy to the balance wheel and this until the arrival of the impulse anchor 8 against the second pin 13. Thus the transmission of energy takes place until the pulse anchor 8 stops, there is therefore no lost stroke of the pulse anchor.

Le plan incliné de la came supérieure 6.1 du plateau supérieur 6 provoque la descente de l'ancre 8 dont la première extrémité 8.1 vient se loger entre deux dents de la denture d'impulsion de la roue d'échappement inférieure 1.3. En descendant, l'ancre d'impulsion 8 entraîne l'axe de blocage 9 jusque dans sa position basse libérant ainsi le mobile d'échappement 1 une fois que l'extrémité 9.1 de l'axe de blocage échappe à la première denture de blocage de la roue d'échappement supérieure 1.5 (Figure 5).The inclined plane of the upper cam 6.1 of the upper plate 6 causes the anchor 8 to descend, the first end 8.1 of which is housed between two teeth of the pulse teeth of the lower escape wheel 1.3. Going down, the impulse anchor 8 drives the locking pin 9 into its low position, thus releasing the exhaust mobile 1 once the end 9.1 of the locking pin escapes the first locking teeth. of the upper escape wheel 1.5 ( Figure 5 ).

Dans la forme d'exécution illustrée, la virole 10 peut se déplacer avec l'axe 9 car l'énergie du ressort 11 utilisé durant la monté/descente de l'axe 9 n'est pas importante. En variante, la virole 10 peut rester fixe en translation via une liaison glissière avec l'axe 9 de l'ancre d'impulsion 8.In the illustrated embodiment, the ferrule 10 can move with the axis 9 because the energy of the spring 11 used during the ascent / descent of the axis 9 is not important. As a variant, the ferrule 10 can remain fixed in translation via a sliding link with the axis 9 of the pulse anchor 8.

Etant libéré, le mobile d'échappement 1 tourne dans le sens contraire des aiguilles d'une montre, ce faisant la denture d'impulsion de la roue d'échappement inférieure 1.3 entraîne l'ancre d'impulsion 8 dans le sens des aiguilles d'une montre contre l'action du ressort auxiliaire 11 jusqu'à ce que le mobile d'échappement soit bloqué par le crochet 14.8 du quatrième bras 14.7 de l'ancre de blocage situé sur le chemin de la seconde denture de blocage de la roue d'échappement intermédiaire 1.4 (Figure 6). Le rouage de finissage et le mobile d'échappement 1 sont alors bloqués par l'ancre de blocage 14 et la roue d'échappement intermédiaire 1.4. L'ancre d'impulsion 8 est bloquée en rotation par la roue d'échappement inférieure 1.3. L'ancre de blocage 14 est maintenue contre la goupille 15 grâce à l'effort de la roue d'échappement intermédiaire 1.4 sur le quatrième bras 14.7 de cette ancre de blocage 14 (l'orientation de l'effort est étudiée comme dans un échappement à ancre suisse classique entre l'ancre et l'échappement). Le dard 14.5 et le plateau de dard 3 évitent tout déblocage intempestif. Le balancier complète sa demi-course.Being released, the exhaust mobile 1 rotates anti-clockwise, thereby making the pulse toothing of the lower escapement wheel 1.3 drives the pulse anchor 8 in the clockwise direction d 'a watch against the action of the auxiliary spring 11 until the exhaust mobile is blocked by the hook 14.8 of the fourth arm 14.7 of the locking anchor located on the path of the second locking wheel teeth 1.4 intermediate exhaust ( Figure 6 ). The gear train and the exhaust mobile 1 are then blocked by the locking anchor 14 and the intermediate escape wheel 1.4. The pulse anchor 8 is prevented from rotating by the lower escape wheel 1.3. The blocking anchor 14 is held against the pin 15 by the force of the intermediate escape wheel 1.4 on the fourth arm 14.7 of this blocking anchor 14 (the orientation of the force is studied as in an escapement classic Swiss anchor between anchor and the exhaust). The dart 14.5 and the dart plate 3 prevent any untimely unlocking. The balance completes its half-stroke.

Par la suite, le balancier inverse son sens de rotation. La cheville 4.1 du plateau de cheville coopère avec la fourchette du second bras 14.3 de l'ancre de blocage (comme dans un échappement à ancre suisse classique) ce qui libère le mobile d'échappement 1, le crochet 14.8 du quatrième bras de l'ancre de blocage échappe à la denture de la roue d'échappement intermédiaire 1.4 (Figure 7).Thereafter, the balance reverses its direction of rotation. The ankle 4.1 of the ankle plate cooperates with the fork of the second arm 14.3 of the blocking anchor (as in a classic Swiss anchor escapement) which releases the exhaust mobile 1, the hook 14.8 of the fourth arm of the locking anchor escapes the toothing of the intermediate escape wheel 1.4 ( Figure 7 ).

Le mobile d'échappement 1 ainsi libéré, il reprend sa rotation dans le sens des aiguilles d'une montre, la denture d'impulsion de la roue d'échappement inférieure 1.3 entraîne la première extrémité 8.1 de l'ancre d'impulsion réarmant le ressort auxiliaire 11 jusqu'à ce que l'ancre d'impulsion vienne buter contre la première goupille 12 (Figure 8).The escapement mobile 1 thus released, it resumes its rotation in a clockwise direction, the pulse toothing of the lower escape wheel 1.3 drives the first end 8.1 of the pulse anchor resetting the auxiliary spring 11 until the pulse anchor abuts against the first pin 12 ( Figure 8 ).

Le plan incliné de la came inférieure 7.1 du plateau de commande inférieur 7 provoque la remontée de l'ancre d'impulsion 8 la dégageant de la roue d'échappement inférieure 1.3. Ce faisant, l'axe de blocage 9 est également relevé et son extrémité de blocage 9.1 vient se loger entre deux dents de la denture de blocage de la roue d'échappement supérieure 1.5 bloquant le mobile d'échappement 1 et le rouage de finissage (Fig. 8). L'extrémité du troisième bras 14.6 de l'ancre de blocage 14 vient bloquer l'ancre d'impulsion 8 et le mécanisme se retrouve en position initiale (Figure 2).The inclined plane of the lower cam 7.1 of the lower control plate 7 causes the pulse anchor 8 to rise, releasing it from the lower escape wheel 1.3. In doing so, the blocking pin 9 is also raised and its blocking end 9.1 is housed between two teeth of the blocking teeth of the upper escapement wheel 1.5 blocking the exhaust mobile 1 and the gear train ( Fig. 8 ). The end of the third arm 14.6 of the blocking anchor 14 blocks the pulse anchor 8 and the mechanism returns to the initial position ( Figure 2 ).

Dans cette première forme d'exécution illustrée, le mobile d'échappement 1 comporte trois roues d'échappement 1.3, 1.4 et 1.5 comportant chacune une denture.In this first illustrated embodiment, the exhaust mobile 1 comprises three escape wheels 1.3, 1.4 and 1.5 each having teeth.

La denture d'impulsion est portée par la roue d'échappement inférieure 1.3 et coopère avec l'ancre d'impulsion 8, la seconde denture de blocage est portée par la roue d'échappement intermédiaire 1.4 et coopère avec le quatrième bras 14.7 de l'ancre de blocage 14, et la première denture de blocage est portée par la roue d'échappement supérieure 1.5 et coopère avec l'axe de blocage 9. Le nombre de roues d'échappement peut être réduit pour autant que le mobile d'échappement 1 comporte les trois dentures coopérant respectivement avec l'ancre d'impulsion 8, l'ancre de blocage 14 et l'axe de blocage 9. Ces trois dentures peuvent en effet être portées par une ou deux roues seulement.The pulse teeth are carried by the lower escape wheel 1.3 and cooperate with the pulse anchor 8, the second locking teeth are carried by the intermediate escape wheel 1.4 and cooperate with the fourth arm 14.7 of the blocking anchor 14, and the first blocking toothing is carried by the upper escape wheel 1.5 and cooperates with the blocking pin 9. The number of escape wheels can be reduced as far as the mobile exhaust 1 comprises the three teeth cooperating respectively with the pulse anchor 8, the locking anchor 14 and the locking pin 9. These three teeth can indeed be carried by one or two wheels only.

Une deuxième forme d'exécution va maintenant être décrite en référence aux figures 9 à 16, dans lesquelles les mêmes références désignent les mêmes éléments que dans la première forme d'exécution.A second embodiment will now be described with reference to Figures 9 to 16 , in which the same references designate the same elements as in the first embodiment.

Le mécanisme d'échappement selon cette deuxième forme d'exécution de l'invention est également destiné à équiper un mouvement d'horlogerie comprenant un balancier-spiral et un mobile d'échappement relié à un barillet par un rouage de finissage.The escapement mechanism according to this second embodiment of the invention is also intended to equip a timepiece movement comprising a balance-spring and an escapement mobile connected to a barrel by a gear train.

Dans cette deuxième forme d'exécution illustrée à titre d'exemple aux figures 9 à 16, le mécanisme d'échappement est un échappement à force constante et comporte un mobile d'échappement 1 comportant, monté sur un axe 1.1, un pignon d'échappement 1.2 relié cinématiquement par un rouage de finissage (non illustré) au barillet (non illustré) d'un mouvement d'horlogerie.In this second embodiment illustrated by way of example to Figures 9 to 16 , the exhaust mechanism is a constant force escapement and includes an exhaust mobile 1 comprising, mounted on an axis 1.1, an exhaust pinion 1.2 kinematically connected by a gear train (not shown) to the barrel (not shown) ) a watch movement.

A la différence de la première forme d'exécution, le mécanisme d'échappement selon cette deuxième forme d'exécution ne comporte pas d'ancre de blocage et le mobile d'échappement 1 comporte uniquement deux roues, soit une roue d'échappement inférieure 1.3 et une roue d'échappement supérieure 1.5 toutes deux solidaires de l'axe 1.1. Ce mobile d'échappement 1 est pivoté sur une partie du bâti du mouvement d'horlogerie telle que la platine ou un pont de ce mouvement d'horlogerie.Unlike the first embodiment, the exhaust mechanism according to this second embodiment does not have a locking anchor and the exhaust mobile 1 only has two wheels, ie a lower escape wheel 1.3 and an upper escape wheel 1.5 both integral with the axis 1.1. This escapement mobile 1 is pivoted on a part of the frame of the timepiece movement such as the plate or a bridge of this timepiece movement.

Ce mécanisme d'échappement comporte encore des organes de commande solidaires de l'axe 2 du balancier-spiral (non illustré) pivoté sur une partie du bâti du mouvement d'horlogerie. Dans cette deuxième forme d'exécution, cet axe 2 du balancier-spiral comporte un plateau d'impulsion 5 comportant un doigt d'impulsion 5.1 et situé entre un plateau de commande supérieur 6 comportant une première came supérieure 6.1 et une seconde came supérieure 6.2 sur sa face inférieure et un plateau de commande inférieur 7 comportant une came inférieure 7.1 sur sa face supérieure faisant face audit plateau de commande supérieur 6. Ces différents plateaux et les éléments qu'ils portent ou comprennent constituent, encore une fois, un ensemble d'organes de commande du mécanisme d'échappement comme cela sera expliqué dans ce qui suit.This escapement mechanism also includes control members integral with the axis 2 of the balance-spring (not shown) pivoted on a part of the frame of the watch movement. In this second embodiment, this axis 2 of the sprung balance comprises a pulse plate 5 comprising a pulse finger 5.1 and located between an upper control plate 6 comprising a first upper cam 6.1 and a second upper cam 6.2 on its lower face and a lower control plate 7 comprising a lower cam 7.1 on its upper face facing said upper control plate 6. These various plates and the elements which they carry or comprise constitute, once again, a set of control members of the exhaust mechanism as will be explained in the following.

Le mécanisme d'échappement selon cette forme d'exécution comporte encore une ancre d'impulsion 8 montée pivotante et coulissante longitudinalement sur une partie du bâti du mouvement d'horlogerie. L'ancre 8 est solidaire d'un axe de blocage 9, perpendiculaire au plan dans lequel elle pivote. Cet axe de blocage 9 s'étend de préférence parallèlement à l'axe 2 du balancier-spiral et à l'axe de rotation 1.1 du mobile d'échappement 1. Tout comme dans la première forme d'exécution, cet axe de blocage 9 est de préférence solidaire d'une virole elle-même solidaire de l'extrémité intérieure d'un ressort spiral auxiliaire de force constante (non illustré afin d'éviter de surcharger les figures) dont l'extrémité extérieure est prévue pour être fixée sur une partie du bâti du mouvement.The escapement mechanism according to this embodiment also includes a pulse anchor 8 pivotally mounted and sliding longitudinally on a part of the frame of the watch movement. The anchor 8 is integral with a locking pin 9, perpendicular to the plane in which it pivots. This blocking axis 9 preferably extends parallel to the axis 2 of the balance spring and the axis of rotation 1.1 of the escapement mobile 1. Just as in the first embodiment, this blocking axis 9 is preferably secured to a ferrule itself secured to the inner end of an auxiliary spiral spring of constant force (not illustrated in order to avoid overloading the figures), the outer end of which is intended to be fixed to a part of the movement frame.

L'ancre d'impulsion 8 comporte une première extrémité 8.1 en forme de dent destinée à coopérer avec les dents d'une denture d'impulsion de la roue d'échappement inférieure 1.3. Cette ancre d'impulsion 8 comporte une seconde extrémité 8.2, s'étendant entre le plateau de commande supérieur 6 et le plateau de commande inférieur 7 solidaires de l'axe du balancier-spiral, destinée à coopérer avec les première et seconde cames supérieures 6.1, 6.2 et la came inférieure 7.1. Une première goupille 12', fixée sur une partie du bâti du mouvement d'horlogerie sert de butée de blocage à l'ancre d'impulsion 8. Dans cette forme d'exécution, le ressort auxiliaire 11 tend à déplacer l'ancre d'impulsion 8 en direction d'une seconde goupille 13.The pulse anchor 8 has a first tooth-shaped end 8.1 intended to cooperate with the teeth of a pulse toothing of the lower escape wheel 1.3. This pulse anchor 8 has a second end 8.2, extending between the upper control plate 6 and the lower control plate 7 secured to the axis of the balance spring, intended to cooperate with the first and second upper cams 6.1 , 6.2 and the lower cam 7.1. A first pin 12 ', fixed on a part of the frame of the clockwork movement serves as a blocking stop for the pulse anchor 8. In this embodiment, the auxiliary spring 11 tends to move the anchor pulse 8 towards a second pin 13.

L'axe de blocage 9 portant l'ancre d'impulsion 8 est susceptible d'être déplacé longitudinalement entre une position haute pour laquelle son extrémité de blocage 9.1 coopère avec une première denture de blocage de la roue d'échappement supérieure 1.5 et empêche toute rotation de celle-ci et une position basse pour laquelle la roue d'échappement supérieure 1.5 est libérée de l'extrémité de blocage 9.1 de cet axe de blocage 9.The locking pin 9 carrying the pulse anchor 8 is capable of being displaced longitudinally between a high position for which its locking end 9.1 cooperates with a first locking gear of the upper escape wheel 1.5 and prevents any rotation of it and a low position for which the upper escape wheel 1.5 is released from the locking end 9.1 of this locking pin 9.

Partant de la position initiale de ce mécanisme d'échappement selon la deuxième forme d'exécution illustrée aux figures 9, 9a, on va dans ce qui suit décrire le fonctionnement de ce mécanisme.Starting from the initial position of this exhaust mechanism according to the second embodiment illustrated in figures 9 , 9a , we will describe in the following how this mechanism works.

Dans la position initiale illustrée aux figures 9, 9a, le mobile d'échappement 1 est bloqué par l'extrémité 9.1 de l'axe de blocage 9. L'ancre d'impulsion 8 est dans une première position intermédiaire pour laquelle sa première extrémité 8.1 est située au-dessus du plan de la roue d'échappement inférieure 1.3 avec laquelle elle ne coopère donc pas et pour laquelle sa seconde extrémité 8.2 coopère avec la première goupille 12' empêchant toute rotation dans le sens anti-horaire (selon les figures) de l'ancre d'impulsion en direction de la goupille 13.In the initial position illustrated in figures 9 , 9a , the exhaust mobile 1 is blocked by the end 9.1 of the locking pin 9. The pulse anchor 8 is in a first intermediate position for which its first end 8.1 is located above the plane of the lower escape wheel 1.3 with which it therefore does not cooperate and for which its second end 8.2 cooperates with the first pin 12 'preventing any rotation in the counterclockwise direction (according to the figures) of the pulse anchor in the direction of the pin 13.

L'ancre d'impulsion 8 est soumise à l'action du couple du ressort auxiliaire 11 qui tend à la faire tourner dans le sens anti-horaire en direction de la goupille 13. Dans la position initiale, l'ancre d'impulsion 8 est maintenue en appui contre la première goupille 12'. Le balancier tourne dans le sens horaire amenant la came inférieure 7.1 du plateau de commande inférieur 7 en contact avec la seconde extrémité 8.2 de l'ancre d'impulsion 8. Le plan incliné de ladite came inférieure 7.1 provoque le déplacement vers le haut de cette ancre d'impulsion 8. Ladite ancre d'impulsion 8 est alors dans sa position haute et n'est plus retenue par la première goupille 12' (Figures 10, 10a). L'ancre d'impulsion 8 est libérée mais le mobile d'échappement 1 est toujours bloqué par l'axe de blocage 9 qui est également dans sa position haute.The pulse anchor 8 is subjected to the action of the torque of the auxiliary spring 11 which tends to make it rotate counterclockwise in the direction of the pin 13. In the initial position, the pulse anchor 8 is held in abutment against the first pin 12 '. The balance wheel rotates clockwise bringing the lower cam 7.1 of the lower control plate 7 into contact with the second end 8.2 of the pulse anchor 8. The inclined plane of said lower cam 7.1 causes the upward movement of this pulse anchor 8. Said pulse anchor 8 is then in its high position and is no longer retained by the first pin 12 '( Figures 10 , 10a ). The pulse anchor 8 is released but the exhaust mobile 1 is still blocked by the locking pin 9 which is also in its high position.

L'ancre d'impulsion 8 libérée se déplace dans le sens anti-horaire sous l'effet du ressort auxiliaire 11. La seconde extrémité 8.2 de l'ancre d'impulsion se trouvant à la hauteur du plateau d'impulsion 5 entre en contact avec le doigt d'impulsion 5.1 (figures 11, 11a) et transmet l'énergie au balancier et ceci jusqu'à l'arrivée de l'ancre d'impulsion 8 contre la seconde goupille 13. Ainsi la transmission d'énergie se fait jusqu'à l'arrêt de l'ancre d'impulsion 8, il n'y a donc pas de course perdue de l'ancre d'impulsion (figures 12, 12a).The released pulse anchor 8 moves counterclockwise under the effect of the auxiliary spring 11. The second end 8.2 of the pulse anchor located at the level of the pulse plate 5 comes into contact with the impulse finger 5.1 ( figures 11 , 11a ) and transmits energy to the balance wheel and this until the arrival of the pulse anchor 8 against the second pin 13. Thus the energy transmission takes place until the pulse anchor 8 stops, there is therefore no lost stroke of the pulse anchor ( figures 12 , 12a ).

Le plan incliné de la seconde came supérieure 6.2 du plateau supérieur 6 provoque la descente de l'ancre 8 de sa position haute dans une seconde position intermédiaire, la première extrémité 8.1 de ladite ancre d'impulsion 8 venant se loger entre deux dents de la denture d'impulsion de la roue d'échappement inférieure 1.3. En descendant, l'ancre d'impulsion 8 entraîne l'axe de blocage 9 jusque dans une position intermédiaire dans laquelle ledit axe de blocage 9 bloque toujours le mobile d'échappement. L'ancre d'impulsion 8 est toujours bloquée par la seconde goupille 13 (figures 13, 13a).The inclined plane of the second upper cam 6.2 of the upper plate 6 causes the anchor 8 to descend from its high position into a second intermediate position, the first end 8.1 of said impulse anchor 8 being received between two teeth of the impulse teeth of the lower escape wheel 1.3. Going down, the pulse anchor 8 drives the locking pin 9 into an intermediate position in which said locking pin 9 always blocks the exhaust mobile. The pulse anchor 8 is always blocked by the second pin 13 ( figures 13 , 13a ).

Le balancier inverse son sens de rotation. Le plan incliné de la première came supérieure 6.1 du plateau supérieur 6 provoque la descente de l'ancre 8 de sa seconde position intermédiaire dans sa position basse, la première extrémité 8.1 de ladite ancre d'impulsion 8 restant logée entre deux dents de la denture d'impulsion de la roue d'échappement inférieure 1.3. En descendant, l'ancre d'impulsion 8 entraîne l'axe de blocage 9 jusque dans sa position basse libérant le mobile d'échappement 1 une fois que l'extrémité 9.1 de l'axe de blocage échappe à la première denture de blocage de la roue d'échappement supérieure 1.5 (Figure 14, 14a).The balance reverses its direction of rotation. The inclined plane of the first upper cam 6.1 of the upper plate 6 causes the anchor 8 to descend from its second intermediate position in its low position, the first end 8.1 of said pulse anchor 8 remaining housed between two teeth of the teeth of the lower escape wheel 1.3. Going down, the impulse anchor 8 drives the locking pin 9 into its low position releasing the exhaust mobile 1 once the end 9.1 of the locking pin escapes the first locking teeth of the upper escape wheel 1.5 ( Figure 14 , 14a ).

Le mobile d'échappement 1 ainsi libéré, il reprend sa rotation dans le sens anti-horaire (selon les figures), la denture d'impulsion de la roue d'échappement inférieure 1.3 entraîne la première extrémité 8.1 de l'ancre d'impulsion dans le sens horaire réarmant le ressort auxiliaire 11 jusqu'à ce que l'ancre d'impulsion vienne buter contre la première goupille 12' (Figure 15, 15a). Cette première goupille 12' est chanfreinée et présente un plan incliné qui, par l'effort de l'ancre d'impulsion 8 poussée contre ladite goupille 12' par le mobile d'échappement 1, provoque la remontée de ladite ancre d'impulsion 8 dans sa première position intermédiaire (position initiale). Ce faisant, la première extrémité 8.1 de l'ancre d'impulsion 8 est dégagée de la roue d'échappement inférieure 1.3. L'axe de blocage 9 est également relevé dans sa position initiale et son extrémité de blocage 9.1 vient se loger entre deux dents de la denture de blocage de la roue d'échappement supérieure 1.5 bloquant le mobile d'échappement 1 et le rouage de finissage. Le mécanisme se retrouve en position initiale (Figure 9, 9a).The escapement mobile 1 thus released, it resumes its rotation in an anti-clockwise direction (according to the figures), the pulse toothing of the lower escape wheel 1.3 drives the first end 8.1 of the pulse anchor clockwise resetting the auxiliary spring 11 until the pulse anchor abuts against the first pin 12 '( Figure 15 , 15a ). This first pin 12 'is chamfered and has an inclined plane which, by the force of the pulse anchor 8 pushed against said pin 12' by the exhaust mobile 1, causes the ascent of said pulse anchor 8 in its first intermediate position (initial position). In doing so, the first end 8.1 of the pulse anchor 8 is released from the lower escape wheel 1.3. The axis of blocking 9 is also raised in its initial position and its blocking end 9.1 is housed between two teeth of the blocking teeth of the upper escapement wheel 1.5 blocking the exhaust mobile 1 and the gear train. The mechanism is returned to the initial position ( Figure 9 , 9a ).

Comme indiqué ci-dessus, dans cette forme d'exécution, le mobile d'échappement 1 comporte deux roues d'échappement 1.3, et 1.5 comportant chacune une denture. La denture d'impulsion est portée par la roue d'échappement inférieure 1.3 et coopère avec l'ancre d'impulsion 8, et la première denture de blocage est portée par la roue d'échappement supérieure 1.5 et coopère avec l'axe de blocage 9. Le nombre de roue d'échappement peut être réduit pour autant que le mobile d'échappement 1 comporte les deux dentures coopérant respectivement avec l'ancre d'impulsion 8 et l'axe de blocage 9. Ces deux dentures peuvent en effet être portées par une roue seulement.As indicated above, in this embodiment, the exhaust mobile 1 comprises two escape wheels 1.3, and 1.5 each having teeth. The pulse toothing is carried by the lower escape wheel 1.3 and cooperates with the pulse anchor 8, and the first blocking teeth is carried by the upper escape wheel 1.5 and cooperates with the locking axis 9. The number of escape wheels can be reduced as long as the exhaust mobile 1 has the two teeth cooperating respectively with the pulse anchor 8 and the locking pin 9. These two teeth can indeed be carried by a wheel only.

Une particularité de ce mécanisme d'échappement selon l'invention est d'avoir séparé la fonction de blocage du mobile d'échappement 1 qui s'effectue soit par l'axe de blocage 9 et le quatrième bras 14.7 de l'ancre de blocage dans la première forme d'exécution, soit par l'axe de blocage 9 uniquement dans la seconde forme d'exécution de la fonction d'impulsion qui est réalisée à l'aide de l'ancre d'impulsion 8 et du ressort auxiliaire 11. En particulier, ces deux fonctions s'effectuent, du moins en partie, dans des plans différents formant un angle entre eux : dans les formes d'exécution illustrées, l'impulsion a lieu dans un plan sensiblement perpendiculaire à l'axe de balancier tandis que la régulation ou le blocage a lieu, du moins en partie, dans un plan comprenant l'axe du mobile d'échappement.A feature of this exhaust mechanism according to the invention is to have separated the locking function of the exhaust mobile 1 which is effected either by the locking pin 9 and the fourth arm 14.7 of the locking anchor in the first embodiment, either by the locking pin 9 only in the second embodiment of the impulse function which is carried out using the impulse anchor 8 and the auxiliary spring 11 In particular, these two functions are performed, at least in part, in different planes forming an angle between them: in the illustrated embodiments, the impulse takes place in a plane substantially perpendicular to the balance axis while regulation or blocking takes place, at least in part, in a plane comprising the axis of the exhaust mobile.

On notera particulièrement que lors de la phase d'impulsion le mobile d'échappement 1, et donc tout le rouage de finissage du mouvement, est bloqué de sorte que l'inertie des pièces en mouvement lors de l'impulsion est très faible, empêchant alors tout recul du mobile d'échappement 1. De plus, la totalité de la course angulaire de l'ancre d'impulsion est effectivement active, sans course morte. Grâce à ces dispositions le rendement du mécanisme d'échappement est nettement amélioré de même que la précision de la chronométrie du mouvement équipé de ce mécanisme d'échappement. Enfin, dans les formes d'exécution décrites, l'énergie transmise au balancier à chaque impulsion est rigoureusement constante car elle ne dépend que du ressort auxiliaire qui se réarme entre chaque impulsion.It will be noted in particular that during the impulse phase, the exhaust mobile 1, and therefore all the gear train for finishing the movement, is blocked so that the inertia of the moving parts during the impulse is very low, preventing then any retreat of the exhaust mobile 1. In addition, the entire angular travel of the pulse anchor is effectively active, without travel dead. Thanks to these provisions, the efficiency of the exhaust mechanism is significantly improved, as is the precision of the timing of the movement equipped with this exhaust mechanism. Finally, in the embodiments described, the energy transmitted to the balance at each pulse is strictly constant because it only depends on the auxiliary spring which rearms between each pulse.

Dans les formes d'exécution illustrées, l'organe de réglage constitué par l'axe de blocage 9 est solidaire de l'ancre d'impulsion 8 et lui sert d'axe de pivotement. Dans des variantes, l'organe de réglage pourrait être indépendant de l'ancre d'impulsion 8 et commandé par une autre paire de cames portées par les plateaux de commande inférieur 7 et supérieur 6 fixés à l'axe 2 du balancier.In the illustrated embodiments, the adjustment member constituted by the locking pin 9 is integral with the pulse anchor 8 and serves as its pivot axis. In variants, the adjusting member could be independent of the pulse anchor 8 and controlled by another pair of cams carried by the lower 7 and upper 6 control plates fixed to the axis 2 of the pendulum.
