Abstract

Two toothed wheels (3,4) one of which is motor driven, engage and give alternate impulses to a rocker (5) by contact between wheel teeth (8,10) and rocker edges (41,42). The toothed wheels are also alternately blocked by separate and more widely spaced rocker projections (43,44). The rocker motion is transmitted to a balance wheel plate (2) by teeth (11,12,13) and rocker bounce is prevented by a tongue (45).

Description

La présente invention est relative à un échappement disposé entre un rouage moteur et un plateau auquel est attaché un balancier d'un garde-temps, le balancier étant apte à parcourir un arc d'oscillation libre et à recevoir des impulsions d'entretien des oscillations, cet échappement comportant des première et seconde roues dentées engrenant l'une avec l'autre, l'une de ces roues étant entraînée par le rouage.The present invention relates to an escapement disposed between a power train and a platform to which a pendulum of a timepiece is attached, the balance being able to traverse a free oscillation arc and to receive oscillation maintenance pulses. , this exhaust having first and second toothed wheels meshing with each other, one of these wheels being driven by the gear train.

Le déposant de la présente invention a déjà proposé un échappement répondant en partie à la définition qui vient d'être donnée et dont une description est explicitée dans le document EP-1221637 , Ce document décrit un échappement représenté à la figure 1, disposé, comme cela est habituel, entre un rouage et un plateau 2 supportant un balancier-spiral d'un garde-temps. Le balancier-spiral, non représenté sur la figure, est apte, comme cela est connu, à parcourir un arc d'oscillation libre et arrangé pour recevoir des impulsions d'entretien de ces oscillations. Par définition, le rouage, appelé aussi finissage, est l'ensemble des roues et pignons qui, d'un barillet, transmet la force motrice à une roue d'échappement. En figure 1, le rouage est représenté par sa dernière roue 30, associée au pignon 31. La roue 30 entraîne une première roue 3 d'échappement par le pignon 32 qui lui est solidaire. La première roue 3 engrène avec une seconde roue 4. Les roues 3 et 4 présentent un même diamètre et un même nombre de dents.The applicant of the present invention has already proposed an escape partially answering the definition which has just been given and a description of which is explained in the document EP-1221637 This document describes an escapement represented at figure 1 , arranged, as is usual, between a cog and a plate 2 supporting a balance-spring of a timepiece. The balance-spring, not shown in the figure, is able, as is known, to go through a free oscillation arc and arranged to receive maintenance pulses of these oscillations. By definition, the wheel, also called finishing, is the set of wheels and gears which, a barrel, transmits the driving force to an escape wheel. In figure 1 , the gear is represented by its last wheel 30, associated with the pinion 31. The wheel 30 drives a first wheel 3 exhaust by the pinion 32 which is secured thereto. The first wheel 3 meshes with a second wheel 4. The wheels 3 and 4 have the same diameter and the same number of teeth.

L'échappement comporte également une bascule 5 apte à recevoir des impulsions engendrées alternativement par les première et seconde roues d'échappement 3 et 4. La bascule 5, à son tour, transmet les impulsions reçues au plateau 2 pour l'entraîner en rotation de façon à entretenir les oscillations du balancier-spiral solidaire de ce plateau 2. De plus, la bascule est arrangée pour bloquer alternativement les première et seconde roues d'échappement 3 et 4, ceci après que chaque impulsion ait été transmise au plateau 2.The exhaust also comprises a rocker 5 adapted to receive pulses generated alternately by the first and second escape wheels 3 and 4. The rocker 5, in turn, transmits the pulses received to the plate 2 to drive it in rotation. in order to maintain the oscillations of the sprung balance integral with this plate 2. In addition, the rocker is arranged to alternately block the first and second escape wheels 3 and 4, after each pulse has been transmitted to the plate 2.

La bascule 5 équipant l'échappement est supportée par un arbre 6 pivotant librement dans une platine (non représentée) que comporte le garde-temps. Cette bascule 5 présente une forme sensiblement triangulaire. Un premier sommet de la bascule définie une arête 19 sur laquelle peut s'appuyer une dent 8 de la première roue 3 pour soumettre la bascule 5 à une impulsion dans un premier sens. Un deuxième sommet de la bascule définie une autre arête 19 sur laquelle peut s'appuyer une dent 10 de la seconde roue 4 pour soumettre la bascule 5 à une impulsion dans un second sens B, inverse au premier sens. Les arêtes 19 de la bascule sont reliées par un bord 14 permettant de bloquer, au voisinage des arêtes, alternativement les première 3 et seconde 4 roues après chaque impulsion transmise. Enfin un troisième sommet de la bascule 5 comporte deux dents 11 et 12 susceptibles d'engrener avec une dent 13 que comporte le plateau 2.The rocker 5 equipping the exhaust is supported by a shaft 6 pivoting freely in a plate (not shown) that includes the timepiece. This rocker 5 has a substantially triangular shape. A first vertex of the rocker defines an edge 19 on which a tooth 8 of the first wheel 3 can rest to subject the rocker 5 to a pulse in a first direction. A second vertex of the rocker defines another edge 19 on which a tooth 10 of the second wheel 4 can rest to subject the rocker 5 to a pulse in a second direction B, which is the opposite of the first direction. The edges 19 of the rocker are connected by an edge 14 to block, in the vicinity of the edges, alternately the first 3 and second 4 wheels after each pulse transmitted. Finally a third top of the rocker 5 comprises two teeth 11 and 12 may mesh with a tooth 13 that includes the plate 2.

Chacune des dents 8, 10 des roues 3 et 4 présente un flanc avant 16 comportant une première découpe 17 sommitale incurvée susceptible de s'appuyer contre le bord 14 de la bascule pour bloquer une des roues, et une seconde découpe 18 en arc de cercle, faisant suite à la première découpe, susceptible de s'appuyer contre une des arêtes 19 pour entraîner la bascule 5 en rotation.Each of the teeth 8, 10 of the wheels 3 and 4 has a leading edge 16 having a first curved top cutout 17 which can bear against the edge 14 of the rocker to block one of the wheels, and a second cutout 18 in an arc. , following the first cut, likely to rest against one of the ridges 19 to drive the rocker 5 in rotation.

Le document EP 1 041 459 décrit un échappement avec deux roues agencées pour transmettre directement les impulsions au plateau du balancier.The document EP 1 041 459 describes an escapement with two wheels arranged to directly transmit the pulses to the balance plate.

La présente invention, qui reprend des caractéristiques décrites dans le document EP 1 221 637 , à savoir deux roues engrenant l'une avec l'autre, l'une de ces roues étant entraînée par le rouage a pour but de fournir un échappement pour garde-temps ayant des performances chronométriques améliorées.The present invention, which includes features described in the document EP 1 221 637 , namely two wheels meshing with each other, one of these wheels being driven by the gear is intended to provide an escapement for timekeeping with improved chronometric performance.

A cet effet, l'échappement de la présente invention qui est définie par la revendication 1, comprend en outre une bascule présentant :

  • des premiers et deuxièmes moyens de contact aptes à recevoir des impulsions engendrées alternativement par les première et seconde roues,
  • des moyens d'impulsion susceptibles de coopérer avec le plateau pour transmettre lesdites impulsions audit plateau pour l'entraîner en rotation et entretenir les oscillations du balancier,
  • et des premiers et deuxièmes moyens de blocage pour bloquer alternativement lesdites première et seconde roues après chaque impulsion transmise par lesdits moyens d'impulsion audit plateau,
  • lesdits premiers et deuxièmes moyens de contact et lesdits premiers et deuxièmes moyens de blocage étant ménagés à la périphérie de la bascule dans des régions distantes les unes des autres.
For this purpose, the escapement of the present invention which is defined by claim 1, further comprises a flip-flop having:
  • first and second contact means adapted to receive pulses generated alternately by the first and second wheels,
  • pulse means capable of cooperating with the plate to transmit said pulses to said plate in order to drive it in rotation and maintain oscillations of the balance,
  • and first and second blocking means for alternately blocking said first and second wheels after each pulse transmitted by said pulse means to said plate,
  • said first and second contact means and said first and second locking means being provided at the periphery of the flip-flop in regions distant from each other.

Selon un mode de réalisation préféré de l'invention, cette bascule est supportée par un arbre pivotant librement dans une platine que comporte le garde-temps et les moyens d'impulsion comprennent des première et deuxième dents susceptibles d'engrener avec une dent que comporte le plateau. Elle présente avantageusement une forme sensiblement symétrique par rapport à un axe passant entre lesdites première et deuxième dents de la bascule et par le centre de l'arbre, dans laquelle :

  • les premiers et deuxièmes moyens de contact sont disposés symétriquement par rapport audit axe,
  • et les premiers et deuxièmes moyens de blocage sont disposés symétriquement par rapport audit axe.
According to a preferred embodiment of the invention, this rocker is supported by a freely pivoting shaft in a plate that includes the timepiece and the pulse means comprise first and second teeth capable of meshing with a tooth that includes the tray. It advantageously has a substantially symmetrical shape with respect to an axis passing between said first and second teeth of the rocker and by the center of the shaft, in which:
  • the first and second contact means are arranged symmetrically with respect to said axis,
  • and the first and second locking means are arranged symmetrically with respect to said axis.

Ainsi, la bascule de l'invention permet non seulement de diminuer l'angle de levée, ce qui permet d'améliorer les performances chronométriques, mais aussi d'augmenter la vitesse d'impulsion en choisissant le bras de levier. En effet, l'introduction dans la présente invention d'une bascule comportant des moyens de contact (et d'impulsion associés) et les moyens de blocage séparés et distants les uns des autres et coopérant avec une dent de l'autre roue, permet :

  • d'augmenter le nombre de dents des roues d'échappement,
  • de faire varier la distance entre le centre du plateau et de la bascule et
  • d'optimiser lors d'une impulsion, l'angle d'attaque d'une dent de la première roue respectivement de la deuxième roue sur respectivement les premiers et deuxièmes moyens de contact.
Il en résulte d'une part que la vitesse périphérique des moyens d'impulsion de la bascule peut être choisie de façon à être supérieure à celle des moyens de contact et d'autre part que la force transmise par les dents des première et deuxième roues d'échappement sur la bascule est sensiblement perpendiculaire au rayon passant par l'axe de rotation de la bascule et le point de contact des dents sur la bascule, ce qui permet une transmission maximale du couple moteur.Thus, the rocker of the invention not only reduces the lift angle, which improves the chronometric performance, but also to increase the pulse speed by choosing the lever arm. Indeed, the introduction in the present invention of a rocker having contact means (and associated pulse) and the locking means separated and spaced from each other and cooperating with a tooth of the other wheel, allows :
  • to increase the number of teeth of the escape wheels,
  • to vary the distance between the center of the plateau and the rocker and
  • to optimize during a pulse, the angle of attack of a tooth of the first wheel respectively of the second wheel on respectively the first and second contact means.
As a result, on the one hand, the peripheral speed of the impulse means of the rocker can be chosen to be greater than that of the contact means and, on the other hand, that the force transmitted by the teeth of the first and second wheels The exhaust on the rocker is substantially perpendicular to the radius passing through the axis of rotation of the rocker and the point of contact of the teeth on the rocker, which allows a maximum transmission of the engine torque.

L'invention va être expliquée maintenant en détail ci-dessous par un mode d'exécution donné en exemple, cette exécution étant illustrée par les dessins annexés parmi lesquels :

  • la figure 1, déjà décrite, est une vue en plan de l'échappement selon l'art antérieur ;
  • les figures 2 à 7 sont des vues en plan de l'échappement selon l'invention représenté à six stades différents décrivant une oscillation complète du balancier.

  • the figure 1 , already described, is a plan view of the exhaust according to the prior art;
  • the Figures 2 to 7 are plan views of the exhaust according to the invention shown at six different stages describing a complete oscillation of the balance.

Les figures 2 à 7 sont des vues en plan de six phases successives de l'échappement selon l'invention, ces phases couvrant une oscillation complète du balancier-spiral. L'échappement représenté sur ces figures successives se distingue de l'échappement de l'art antérieur dans la structure de la bascule 5 utilisée ainsi que dans la forme des dents 8 et 10 des roues 3 et 4 d'échappement. Les autres éléments, communs aux deux échappements, ont déjà été décrits à la figure 1.The Figures 2 to 7 are plan views of six successive phases of the escapement according to the invention, these phases covering a complete oscillation of the sprung balance. The exhaust shown in these successive figures differs from the exhaust of the prior art in the structure of the rocker 5 used and in the form of the teeth 8 and 10 of the wheels 3 and 4 exhaust. The other elements, common to both exhausts, have already been described in figure 1 .

Comme le montre la figure 2, la bascule 5 équipant l'échappement selon l'invention est supportée par un arbre 6 pivotant librement dans une platine (non représentée) que comporte le garde-temps. Cette bascule 5 comprend des premiers et deuxièmes moyens de contact respectivement formés par des première 41 et deuxième 42 arêtes aptes à recevoir des impulsions engendrées alternativement par les première 3 et seconde 4 roues. Elle comprend également des moyens d'impulsions comprenant des première et deuxième dents 11 et 12 susceptibles d'engrener avec une dent 13 que comporte un plateau 2 pour transmettre ces impulsions au plateau pour l'entraîner en rotation et entretenir les oscillations du balancier.As shown in figure 2 , the rocker 5 equipping the exhaust according to the invention is supported by a shaft 6 pivoting freely in a plate (not shown) that includes the timepiece. This flip-flop 5 comprises first and second contact means respectively formed by first 41 and second 42 edges adapted to receive pulses generated alternately by the first 3 and second 4 wheels. It also comprises pulse means comprising first and second teeth 11 and 12 capable of to mesh with a tooth 13 that includes a plate 2 to transmit these pulses to the plate to drive it in rotation and maintain oscillations of the balance.

On notera à ce propos que le plateau 2 comprend un plateau inférieur 2a muni de la dent 13 et d'un plateau supérieur 2b ayant un diamètre sensiblement inférieur muni d'une encoche 46 en forme d'un arc de cercle s'ouvrant sur la dent 13 dont la fonction sera expliquée par la suite.Note in this regard that the plate 2 comprises a lower plate 2a provided with the tooth 13 and an upper plate 2b having a substantially smaller diameter provided with a notch 46 in the form of a circular arc opening on the tooth 13 whose function will be explained later.

Elle comprend en outre des premiers et deuxièmes moyens de blocage formés par des première 43 et deuxième 44 faces de blocage pour bloquer alternativement les première 3 et seconde 4 roues après chaque impulsion transmise. Il est à noter que les première 41 et deuxième 42 arêtes et les première 43 et deuxième 44 faces de blocage sont ménagées à la périphérie de la bascule 5 dans des régions distantes les unes des autres.It further comprises first and second locking means formed by first 43 and second 44 locking faces to alternately block the first 3 and second 4 wheels after each transmitted pulse. It should be noted that the first 41 and second 42 edges and the first 43 and second 44 locking faces are formed at the periphery of the latch 5 in regions distant from each other.

Cette bascule 5 présente de préférence une forme sensiblement symétrique par rapport à un axe (X-X) passant entre les première et deuxième dents 11 et 12 de la bascule et par le centre de l'arbre 6. Les premiers et deuxièmes moyens de contact sont disposés symétriquement par rapport à cet axe (X-X) ainsi que les premiers et deuxièmes moyens de blocage.This rocker 5 preferably has a substantially symmetrical shape with respect to an axis (XX) passing between the first and second teeth 11 and 12 of the rocker and by the center of the shaft 6. The first and second contact means are arranged symmetrically with respect to this axis (XX) as well as the first and second locking means.

Il est à noter que l'angle (a) formé par le segment reliant les premiers moyens de contact au centre de l'arbre et le segment reliant les deuxièmes moyens de contact au centre de l'arbre, est un angle aigu compris de préférence entre 50° et 70°. Cet angle (a), représenté à la figure 2, est avantageusement égal à 60°.It should be noted that the angle (a) formed by the segment connecting the first contact means to the center of the shaft and the segment connecting the second contact means to the center of the shaft, is an acute angle preferably comprised between 50 ° and 70 °. This angle (a), represented at figure 2 , is advantageously equal to 60 °.

Il est également à noter que l'angle (b) formé par le segment reliant les premiers moyens de blocage au centre de l'arbre et le segment reliant les deuxièmes moyens de blocage au centre de l'arbre, est un angle obtus compris de préférence entre 130° et 170°. Cet angle (b), représenté à la figure 3, est avantageusement égal à 155°.It should also be noted that the angle (b) formed by the segment connecting the first locking means to the center of the shaft and the segment connecting the second locking means to the center of the shaft, is an obtuse angle inclusive of preferably between 130 ° and 170 °. This angle (b), represented at figure 3 , is advantageously equal to 155 °.

La première arête 41 formant les premiers moyens de contact, coopère avec l'extrémité d'une dent 8 de la première roue 3 pour soumettre la bascule 5 à une impulsion dans un premier sens (B) (voir figure 3). Et la deuxième arête 42 formant les deuxièmes moyens de contact, coopère avec l'extrémité d'une dent 10 de la seconde roue 4 pour soumettre la bascule 5 à une impulsion dans un second sens (A), inverse au premier sens (B) (voir figure 7).The first edge 41 forming the first contact means, cooperates with the end of a tooth 8 of the first wheel 3 to subject the rocker 5 to a pulse in a first direction (B) (see figure 3 ). And the second edge 42 forming the second contact means, cooperates with the end of a tooth 10 of the second wheel 4 to subject the rocker 5 to a pulse in a second direction (A), inverse to the first direction (B) (see figure 7 ).

La première face de blocage 43 coopère avec l'extrémité d'une dent 8 de la roue 3, voisine de la dent 8 ayant précédemment servi pour soumettre la bascule à une impulsion dans le sens B, pour bloquer la bascule (voir figure 4). Et la deuxième face de blocage 44 coopère avec l'extrémité d'une dent 10 de la roue 4, voisine de la dent 10 ayant précédemment servi pour soumettre la bascule à une impulsion dans le sens A, pour bloquer la bascule.The first blocking face 43 cooperates with the end of a tooth 8 of the wheel 3, adjacent to the tooth 8 having previously served to subject the rocker to a pulse in the direction B, to block the rocker (see figure 4 ). And the second locking face 44 cooperates with the end of a tooth 10 of the wheel 4, close to the tooth 10 having previously served to subject the rocker to a pulse in the direction A, to block the rocker.

On observera également que chacune des dents 8, 10 respectivement des première 3 et seconde 4 roues présente un flanc avant 16 comportant une découpe 21 incurvée susceptible de coopérer respectivement avec les première 43 et deuxième 44 faces de blocage de la bascule pour bloquer une des roues, et également susceptible de s'appuyer respectivement contre les première 41 et deuxième arêtes 42 de la bascule pour entraîner la bascule en rotation.It will also be observed that each of the teeth 8, 10 respectively of the first 3 and second 4 wheels has a front flank 16 having a curved cutout 21 capable of cooperating respectively with the first 43 and second 44 blocking faces of the rocker to block one of the wheels. , and also capable of bearing respectively against the first 41 and second edges 42 of the rocker to drive the rocker in rotation.

Comme il est important d'éviter un renversement (dû par exemple à un choc) de la bascule 5 pendant le parcours de l'arc d'oscillation libre du balancier et donc du plateau 2 auquel il est attaché, il est prévu une languette 45 ayant de préférence une extrémité terminée en pointe, placée dans un plan parallèle à celui dans lequel s'étend les dents 11 et 12 de la bascule. Ainsi, au cours de l'arc d'oscillation libre, la languette 45 empêche un renversement de la bascule 5 par exemple en cas de choc par le blocage de cette dernière à la périphérie 20 du plateau supérieur 2b.Since it is important to avoid a reversal (due for example to a shock) of the rocker 5 during the course of the free oscillation arc of the balance and therefore of the plate 2 to which it is attached, a tongue 45 is provided. preferably having a tip terminated end, placed in a plane parallel to that in which the teeth 11 and 12 of the rocker. Thus, during the free oscillation arc, the tongue 45 prevents a reversal of the rocker 5 for example in case of impact by blocking the latter at the periphery 20 of the upper plate 2b.

Enfin on comprendra qu'il est important de limiter l'excursion angulaire de la bascule 5. On utilisera pour cela deux goupilles 25 et 26 fichées dans la platine du garde-temps. Les dents 11 et 12 de la bascule 5 viennent buter contre les goupilles comme représentées aux figures 2 et 4, limitant ainsi l'excursion de la bascule.Finally we understand that it is important to limit the angular excursion of the rocker 5. It will use two pins 25 and 26 stuck in the plate of the timepiece. The teeth 11 and 12 of the rocker 5 abut against the pins as shown in FIG. figures 2 and 4 , thus limiting the excursion of the rocker.

Un mode de réalisation préféré du nouvel échappement ayant été décrit ci-dessus ainsi que les fonctions remplies par les diverses pièces les composant, on va passer en revue maintenant son mode de fonctionnement proprement dit en décrivant un cycle de marche complet. On examinera tour à tour les figures 2 à 7 qui montrent six phases importantes de ce cycle.A preferred embodiment of the new exhaust having been described above as well as the functions performed by the various parts composing them, we will now review its actual operating mode by describing a complete operating cycle. We will examine in turn the Figures 2 to 7 which show six important phases of this cycle.

Première phase (figure 2)First phase (Figure 2)

Le mécanisme est à l'arrêt. La seconde roue d'échappement 4 est bloquée car la découpe incurvée 21 de sa dent 10 est en contact avec la deuxième face 44 de blocage de la bascule 5. L'excursion angulaire de la bascule 5 est à bout de course puisque sa dent 12 est en butée sur la goupille 26. A ce moment le balancier-spiral est proche de la fin d'oscillation (flèche E) ou proche de la fin de seconde alternance de cette oscillation. La dent 13 du plateau 2 entre en contact avec la dent 11 de la bascule 5 et va entraîner ladite bascule dans le sens de la flèche B. C'est une phase de dégagement de la bascule où d'une part la dent 12 est entraînée de manière à s'éloigner de la goupille 26 et où d'autre part la deuxième face 44 de blocage de la bascule peut s'effacer devant la découpe incurvée 21 de la dent 10.The mechanism is stopped. The second escape wheel 4 is blocked because the curved cutout 21 of its tooth 10 is in contact with the second locking face 44 of the rocker 5. The angular excursion of the rocker 5 is at the end of its stroke since its tooth 12 is in abutment on the pin 26. At this time the sprung balance is close to the end of oscillation (arrow E) or close to the end of second alternation of this oscillation. The tooth 13 of the plate 2 comes into contact with the tooth 11 of the rocker 5 and will cause said rocker in the direction of the arrow B. It is a phase of disengagement of the rocker where on the one hand the tooth 12 is driven so as to move away from the pin 26 and where on the other hand the second blocking face 44 of the rocker can fade before the curved cutout 21 of the tooth 10.

Deuxième phase (figure 3)Second phase (Figure 3)

La bascule 5 continue sa course dans le sens de la flèche B, entraînée qu'elle est par le plateau 2. A ce moment la dent 13 du plateau est totalement engagée entre les deux dents 11 et 12 de la bascule 5. On remarquera que l'encoche 46 du plateau supérieur 2b autorise dans cette position le passage de la languette 45 et donc la rotation de la bascule 5. La découpe incurvée 21 de la dent 8a de la première roue entre en contact avec la première arête 41 de la bascule. La roue d'échappement 4 est alors entraînée dans le sens de la flèche F par l'intermédiaire de la roue d'échappement 3 qui tourne dans le sens de la flèche G entraînée qu'elle est à son tour par le rouage dont le dernier élément 30 a été montré en figure 1. C'est une phase d'impulsion qui lance le plateau dans le sens de la flèche E et fait tourner la bascule dans le sens de la flèche B jusqu'à ce que la première face 43 de blocage de la bascule rencontre la découpe incurvée de la dent 8b de la première roue d'échappement, voisine de la dent 8a dans le sens inverse de rotation de la roue 3.The latch 5 continues its course in the direction of the arrow B, driven that it is by the plate 2. At this moment the tooth 13 of the plate is fully engaged between the two teeth 11 and 12 of the rocker 5. It will be noted that the notch 46 of the upper plate 2b allows in this position the passage of the tongue 45 and thus the rotation of the rocker 5. The curved cutout 21 of the tooth 8a of the first wheel comes into contact with the first edge 41 of the rocker . The escape wheel 4 is then driven in the direction of the arrow F by means of the escape wheel 3 which rotates in the direction of the arrow G driven that it is in turn by the wheel whose last element 30 was shown in figure 1 . It is a pulse phase which launches the plate in the direction of the arrow E and turns the rocker in the direction of the arrow B until the first face 43 of blocking of the rocker meets the curved cut of the tooth 8b of the first escape wheel, close to the tooth 8a in the opposite direction of rotation of the wheel 3.

Troisième phase (figure 4)Third phase (Figure 4)

Quand la dent 13 du plateau 2 quitte la dent 12 de la bascule, la première face 43 de blocage de la bascule bute sur la découpe incurvée 21 de la dent voisine 8b de la première roue d'échappement 3 bloquant ainsi les première et seconde roues 3 et 4. Dès ce moment le plateau 2 débute une seconde oscillation en direction de la flèche E. La bascule est alors retenue par la dent 11 qui appuie contre la goupille 25.When the tooth 13 of the plate 2 leaves the tooth 12 of the rocker, the first face 43 of locking of the rocker abuts on the curved cutout 21 of the adjacent tooth 8b of the first escape wheel 3 thus blocking the first and second wheels 3 and 4. From this moment the plate 2 starts a second oscillation in the direction of the arrow E. The rocker is then retained by the tooth 11 which bears against the pin 25.

Quatrième phase (figure 5)Fourth phase (Figure 5)

La situation de la bascule 5 est la même que celle décrite ci-dessus à la différence près que la languette 45 empêche tout renversement. Le plateau 2 continue à tourner dans le sens de la flèche E et parcourt la première alternance de sa seconde oscillation libre. La bascule 5 et les première et seconde roues 3 et 4 sont toujours bloquées.The situation of the flip-flop 5 is the same as that described above with the difference that the tab 45 prevents any reversal. The plate 2 continues to rotate in the direction of arrow E and travels the first half of its second free oscillation. The rocker 5 and the first and second wheels 3 and 4 are still blocked.

Cinquième phase (figure 6)Fifth phase (Figure 6)

Après avoir parcouru sa première alternance, le plateau 2 revient en sens inverse montré par la flèche M et parcourt la seconde alternance de sa seconde oscillation libre. La bascule 5 bloque toujours les première et seconde roues et est toujours empêchée de se renverser grâce à la languette 45.After having traversed its first alternation, the plateau 2 returns in the opposite direction shown by the arrow M and travels the second alternation of its second free oscillation. The rocker 5 always blocks the first and second wheels and is always prevented from overturning thanks to the tongue 45.

Sixième phase (figure 7)Sixth phase (Figure 7)

La dent 13 du plateau 2 entre en contact avec la dent 12 de la bascule 5 ce qui va entraîner cette dernière dans le sens de la flèche A. On se retrouve ici dans une situation semblable à celle illustrée par la figure 1, c'est-à-dire au début d'une nouvelle phase de dégagement où d'une part la dent 11 est entraînée de manière à s'éloigner de la goupille 25 et où d'autre part la première face 43 de blocage de la bascule peut s'effacer devant la découpe incurvée 21 de la dent 8 de la première roue 3 et qui va permettre à la dent 10a de la deuxième roue 4 de s'appuyer sur la deuxième arête 42 de la bascule 5 pour relancer à nouveau le plateau 2. A partir de cette sixième phase un nouveau cycle recommence semblable à celui qui vient d'être décrit, le prochain blocage agissant alors sur la seconde roue d'échappement 4 par l'intermédiaire de la roue 10b, voisine de la roue 10adans le sens inverse de rotation de la roue 4, sur la deuxième face de blocage 44 de la bascule.The tooth 13 of the plate 2 comes into contact with the tooth 12 of the rocker 5 which will cause the latter in the direction of the arrow A. Here we find ourselves in a situation similar to that illustrated by the figure 1 , that is to say at the beginning of a new phase of clearance where on the one hand the tooth 11 is driven away from the pin 25 and on the other hand the first face 43 of blocking of the rocker can fade before the curved cutout 21 of the tooth 8 of the first wheel 3 and which will allow the tooth 10a of the second wheel 4 to rest on the second edge 42 of the rocker 5 to relaunch again plateau 2. From this sixth phase a new cycle starts again similar to that just described, the next block then acting on the second escape wheel 4 via the wheel 10b, close to the wheel 10adans the opposite direction of rotation of the wheel 4, on the second blocking face 44 of the rocker.

Considérations finalesFinal considerations

On notera que les première et deuxième roues d'échappement ont une structure permettant de disposer plus de dents à leur périphérie, ainsi le couple nécessaire pour entraîner le barillet est moins important et donc l'énergie consommée est plus faible.Note that the first and second exhaust wheels have a structure to have more teeth at their periphery, and the torque required to drive the barrel is less important and therefore the energy consumed is lower.
