Description

La présente invention est relative à un échappement disposé entre un rouage 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 entraínée par le rouage.The present invention relates to an exhaust disposed between a gear train and a plate to which is attached a pendulum of a timepiece, the pendulum being able to traverse a free oscillation arc and to receive maintenance pulses from oscillations, this exhaust comprising first and second toothed wheels meshing with each other, one of these wheels being driven by the 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-A-1 041 459. Ce document décrit un échappement comprenant des première et seconde roues engrenant l'une avec l'autre. L'une de ces roues est entraínée par le rouage. Des premier et second plateaux solidaires d'un arbre commun supportent un balancier-spiral. Les roues et le premier plateau sont pourvus de moyens permettant audit premier plateau de recevoir des impulsions directes délivrées alternativement par les première et seconde roues en vue d'entretenir les oscillations du balancier. Le second plateau est pourvu de moyens pour entraíner une bascule de blocage arrangée pour bloquer alternativement lesdites première et seconde roues.The applicant of the present invention has already proposed an exhaust partially meeting the definition which has just been given and a description of which is explained in document EP-A-1 041 459. This document describes an escape comprising first and second wheels meshing with each other. One of these wheels is driven by the cog. First and second trays secured to a common tree support a balance-spring. The wheels and the first plate are provided with means allowing said first plate to receive pulses direct delivered alternately by the first and second wheels in sight to maintain the pendulum's oscillations. The second tray is provided with means to drive a blocking rocker arranged to alternately block said first and second wheels.

La présente invention reprend donc un caractère essentiel de ce qui est décrit dans le document cité, à savoir deux roues engrenant l'une avec l'autre, l'une de ces roues étant entraínée par le rouage. Cependant l'idée développée dans la citation d'utiliser deux plateaux superposés, l'un servant à recevoir des impulsions directes conférées alternativement par les première et seconde roues et l'autre servant à bloquer alternativement, par l'intermédiaire d'une bascule, lesdites première et seconde roues, a été abandonnée dans la présente invention pour des raisons évidentes de simplification du mécanisme.The present invention therefore takes up an essential character from what is described. in the cited document, namely two wheels meshing with one another, one of these wheels being driven by the cog. However the idea developed in the quote to use two superimposed trays, one used to receive direct pulses conferred alternately by the first and second wheels and the other serving to alternately block, by means of a rocker, said first and second wheel, has been abandoned in the present invention for reasons obvious simplification of the mechanism.

Comme on le verra de la description qui va suivre, un plateau unique supportant le balancier-spiral coopère avec une bascule qui coopère à son tour et alternativement avec les première et seconde roues. On comprendra donc que tout le mécanisme d'échappement est confiné dans un seul plan et qu'ainsi l'encombrement en hauteur de ce mécanisme est diminué de moitié par rapport à l'encombrement occupé par l'échappement du document cité.As will be seen from the description which follows, a single plate supporting the balance-spring cooperates with a rocker which in turn cooperates and alternately with the first and second wheels. We will therefore understand that all exhaust mechanism is confined in a single plane and that thus the size in height of this mechanism is halved compared to the size occupied by the escape of the cited document.

Ainsi l'échappement de la présente invention est-il caractérisé en ce qu'il comporte en outre une bascule apte à recevoir des impulsions engendrées alternativement par les première et seconde roues et à transmettre ces impulsions au plateau pour l'entraíner en rotation et entretenir les oscillations du balancier, ladite bascule étant arrangée pour bloquer alternativement lesdites première et seconde roues après chaque impulsion transmise.Thus the exhaust of the present invention is characterized in that it further includes a rocker capable of receiving generated pulses alternately by the first and second wheels and to transmit these impulses to the plate to drive it in rotation and maintain the pendulum oscillations, said rocker being arranged to alternately block said first and second wheels after each pulse transmitted.

On aura donc compris que la bascule de l'invention remplit une double fonction : celle d'abord de transmettre au plateau les impulsions reçues alternativement des première et seconde roues et celle ensuite de bloquer alternativement lesdites roues après chaque impulsion.It will therefore be understood that the scale of the invention fulfills a double function: that of first transmitting the pulses received to the plate alternately first and second wheels and then blocking alternately said wheels after each pulse.

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 :

  • les figures 1 à 6 sont des vues en plan de l'échappement selon l'invention représenté en six stades différents décrivant une oscillation complète du balancier,
  • la figure 7 est un agrandissement de la zone VII montrée en figure 2, et
  • la figure 8 est un agrandissement de la zone VIII montrée en figure 3.
The invention will now be explained in detail below by an embodiment given as an example, this embodiment being illustrated by the appended drawings among which:
  • FIGS. 1 to 6 are plan views of the escapement according to the invention represented in six different stages describing a complete oscillation of the balance,
  • FIG. 7 is an enlargement of zone VII shown in FIG. 2, and
  • FIG. 8 is an enlargement of zone VIII shown in FIG. 3.

Les figures 1 à 6 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 1 est 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 les figures, 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 entraíne 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. On remarquera ici que la roue de finissage 30 pourrait entraíner la seconde roue d'échappement 4 à la place de la première roue 3.Figures 1 to 6 are plan views of six successive phases of the exhaust according to the invention, these phases covering a complete oscillation of the sprung balance. The exhaust 1 is arranged, as usual, between a cog and a plate 2 supporting a balance-spring of a timepiece. The balance-spring, not shown in the figures, is capable, as is known, of traversing a free oscillation arc arranged to receive maintenance pulses from these oscillations. By definition, the cog, also called finishing, is the set of wheels and pinions which, from a barrel, transmits the driving force to an escape wheel. In Figure 1, the train is represented by its last wheel 30, associated with the pinion 31. The wheel 30 drives a first exhaust wheel 3 through the pinion 32 which is solidarity. 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. Note here that the finishing wheel 30 could drive the second escape wheel 4 instead of the first wheel 3.

Ce qui vient d'être dit est connu du document EP-A-1 041 459 qui montre déjà un échappement comportant deux roues engrenant l'une avec l'autre et arrangées pour transmettre des impulsions directes à un premier plateau tandis qu'un second plateau entraíne une bascule bloquant tour à tour la première puis la seconde roue d'échappement.What has just been said is known from document EP-A-1 041 459 which already shows an exhaust comprising two wheels meshing with each other and arranged to transmit direct impulses to a first plate while a second platform causes a rocker blocking in turn the first then the second wheel exhaust.

Par rapport à cette disposition antérieure, la présente invention est remarquable en ce qu'elle comporte une bascule 5 apte à recevoir des impulsions engendrées alternativement par les première et seconde roues d'échappement 3 et 4 comme le montrent bien les figures accompagnant cette description. De façon tout à fait générale, ces figures rendent évident le fait que la bascule 5, à son tour, transmet les impulsions reçues au plateau 2 pour l'entraíner en rotation de façon à entretenir les oscillations du balancier-spiral solidaire de ce plateau 2. Les mêmes figures rendent aussi apparent le fait que 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.Compared to this prior arrangement, the present invention is remarkable in that it comprises a rocker 5 capable of receiving pulses generated alternately by the first and second escape wheels 3 and 4 as the figures accompanying this description clearly show. So completely general fact, these figures make it obvious that the flip-flop 5, in turn, transmits the pulses received on the plate 2 to drive it in rotation so as to maintain the oscillations of the balance-spring fixed to this plate 2. The same figures also make it apparent that the rocker is arranged to block alternately the first and second escape wheels 3 and 4, this after each pulse has been transmitted to plate 2.

On va examiner maintenant plus en détail un mode d'exécution préféré de l'invention qui permet de mettre en oeuvre le principe d'échappement défini au paragraphe ci-dessus.We will now examine in more detail a preferred embodiment of the invention which enables the exhaust principle defined in paragraph above.

Comme le montrent les figures, 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 présente une forme sensiblement triangulaire.As shown in the figures, 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 has a shape substantially triangular.

Un premier sommet de la bascule comporte un premier logement 7 dans lequel peut s'introduire l'extrémité d'une dent 8 de la première roue 3 pour soumettre la bascule 5 à une impulsion dans un premier sens A. Cette situation d'introduction n'est pas représentée au dessin, mais on comprendra qu'elle suit la phase présentée en figure 6.A first top of the rocker comprises a first housing 7 in which can introduce the end of a tooth 8 of the first wheel 3 to submit flip-flop 5 to a pulse in a first direction A. This situation of introduction is not represented in the drawing, but it will be understood that it follows the phase presented in figure 6.

Un deuxième sommet de la bascule comporte un second logement 9 dans lequel peut s'introduire l'extrémité d'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 A. Cette situation est représentée au dessin à la figure 2 ainsi qu'à la figure 7 qui est un agrandissement de la zone VII de la figure 2.A second top of the scale comprises a second housing 9 in which can introduce the end of a tooth 10 of the second wheel 4 to subject flip-flop 5 to a pulse in a second direction B, reverses to the first direction A. This situation is represented in the drawing in FIG. 2 as well as in FIG. 7 which is a enlargement of zone VII of figure 2.

Enfin un troisième sommet de la bascule 5 comporte deux dents 11 et 12 susceptibles d'engrener avec une dent unique 13 que comporte le plateau 2, une situation d'engrènement total étant bien apparent aux figures 2 et 7.Finally a third top of the rocker 5 has two teeth 11 and 12 likely to mesh with a single tooth 13 that comprises the plate 2, a situation of total meshing being very apparent in FIGS. 2 and 7.

On va expliquer maintenant comment les dents des deux roues coopèrent avec la bascule 5 pour soumettre ladite bascule à des impulsions et pour bloquer cette même bascule après chaque impulsion transmise.We will now explain how the teeth of two wheels cooperate with rocker 5 to subject said rocker to pulses and to block this same rocker after each pulse transmitted.

On notera tout d'abord, en se référant aux figures 7 et 8, que les premier et second logements 7 et 9 de la bascule 5 sont reliés par un bord 14 présentant une configuration circulaire dont le rayon de courbure R1 passe par l'axe 15 de l'arbre 6 qui supporte la bascule 5. On observera également que les dents des première et seconde roues 3 et 4 présentent chacune un flanc avant 16 défini comme faisant face au sens d'avance respectif de chacune des roues. Chaque flanc avant 16 comporte une première découpe sommitale incurvée 17, dite face de blocage, dont le rayon de courbure R2 est sensiblement le même que le rayon de courbure R1 du bord 14 reliant les premier et second logements 7 et 9 de la bascule 5. Comme le montre bien la figure 8, cette face de blocage 17 vient s'appuyer contre le bord 14 de la bascule 5 pour bloquer une des roues 3 et 4, en l'occurrence ici la roue 3. Une situation semblable, bloquant la roue 4, est montrée en figure 1. Chaque flanc avant 16 comporte aussi une seconde découpe 18, en arc de cercle, appelée face d'impulsion, cette seconde découpe 18 faisant suite à la première découpe 17. Comme le montre bien la figure 7, cette face d'impulsion 18 vient s'appuyer contre une arête 19 définie comme étant l'intersection du bord 14 de la bascule 5 et d'un des logements 7 et 9 de la même bascule, en l'occurrence ici le logement 9. Cet appui entraíne la bascule 5 en rotation dans le sens de la flèche B et, par voie de conséquence, entraíne le plateau 2 dans le sens de la flèche E. L'impulsion est ainsi donnée au balancier-spiral.First of all, it will be noted, with reference to FIGS. 7 and 8, that the first and second housings 7 and 9 of the rocker 5 are connected by an edge 14 having a circular configuration whose radius of curvature R1 passes through the axis 15 of the shaft 6 which supports the rocker 5. We will also observe that the teeth of the first and second wheels 3 and 4 each have a front flank 16 defined as facing in the respective direction of advance of each of the wheels. Each front flank 16 comprises a first curved top cut 17, called blocking face, the radius of which curvature R2 is roughly the same as the radius of curvature R1 from edge 14 connecting the first and second housings 7 and 9 of the scale 5. As shown well Figure 8, this locking face 17 bears against the edge 14 of the rocker 5 to lock one of the wheels 3 and 4, in this case here the wheel 3. A situation similar, blocking the wheel 4, is shown in FIG. 1. Each front flank 16 also includes a second cutout 18, in an arc, called a pulse face, this second cut 18 following the first cut 17. As shown Figure 7, this impulse face 18 comes to bear against a defined edge 19 as being the intersection of the edge 14 of the rocker 5 and one of the housings 7 and 9 of the same rocker, in this case the housing 9. This support causes the rocker 5 in rotation in the direction of arrow B and, consequently, causes the plate 2 in the direction of arrow E. The impulse is thus given to the balance-spring.

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, on dimensionnera chacune des deux dents 11 et 12 occupant le troisième sommet de la bascule 5 pour qu'elles jouxtent le bord 20 du plateau 2. De telles situations sont montrées sur les figures 4 et 5.As it is important to avoid overturning (due for example to a shock) of rocker 5 during the course of the free swinging arc of the pendulum and therefore of the plate 2 to which it is attached, we will size each of the two teeth 11 and 12 occupying the third vertex of the scale 5 so that they adjoin the edge 20 of the tray 2. Such situations are shown in Figures 4 and 5.

Enfin on comprendra qu'il est important de limiter l'excursion angulaire de la bascule 5. Cette limitation peut être faite selon deux exécutions différentes.Finally it will be understood that it is important to limit the angular excursion of the flip-flop 5. This limitation can be made according to two different executions.

Une première exécution consiste à pourvoir les premier et deuxième sommets de la bascule 5 de première et, respectivement, de seconde cornes 21 et 22 comme le montrent toutes les figures et particulièrement la figure 8. La première corne 21 vient buter contre le flanc arrière 23 d'une dent 24 de la première roue 3 comme le montre la figure 1. De même, la seconde corne 22 vient buter contre le flanc arrière d'une dent 10 de la seconde roue 4 comme on le voit sur les figures 3 et 8. A noter ici que le flanc arrière 23 des dents en question est défini comme tournant le dos au sens d'avance respectif de chacune des roues.A first execution consists in providing the first and second vertices of the rocker 5 of the first and, respectively, of the second horns 21 and 22 as all the figures show this, and in particular FIG. 8. The first horn 21 abuts against the rear flank 23 of a tooth 24 of the first wheel 3 as the shows Figure 1. Similarly, the second horn 22 abuts against the rear flank a tooth 10 of the second wheel 4 as seen in Figures 3 and 8. Note here that the rear flank 23 of the teeth in question is defined as turning its back on the respective direction of advance of each wheel.

Une seconde exécution consiste à limiter l'exécution de la bascule 5 au moyen de deux goupilles 25 et 26 fichées dans la platine du garde-temps comme cela est montré en pointillés sur la figure 8. On comprendra alors que les cornes 21 et 22 équipant la bascule 5 ne sont plus nécessaires et qu'on peut les enlever. A ce moment les premier et deuxième sommets de la bascule 5 pourraient se terminer selon les pointillés 35, respectivement 36 qui pourraient être le prolongement du bord en arc de cercle 14 reliant les logements 7 et 9.A second execution consists in limiting the execution of the flip-flop 5 by means of two pins 25 and 26 inserted in the plate of the timepiece as is shown in dotted lines in FIG. 8. It will then be understood that the horns 21 and 22 equipping the scale 5 are no longer necessary and can be removed. At this moment the first and second vertices of rocker 5 could end according to the dotted lines 35, respectively 36 which could be an extension of the edge in an arc 14 connecting the housings 7 and 9.

Un mode d'exécution 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 1 à 6 qui montrent six phases importantes de ce cycle. A preferred embodiment of the new exhaust having been described above as well as the functions fulfilled by the various component parts, we will now review its actual mode of operation by describing a complete walking cycle. We will examine in turn Figures 1 to 6 which show six important phases of this cycle.

Première phase (figure 1)First phase (Figure 1)

Le mécanisme est à l'arrêt. La seconde roue d'échappement 4 est bloquée car la face de blocage de sa dent 10 repose sur le bord 14 reliant les logements 7 et 9 de la bascule 5. L'excursion angulaire de la bascule 5 est à bout de course puisque sa corne 21 repose sur le flanc arrière 23 de la dent 24 de la première roue d'échappement 3. 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 12 de la bascule 5 et va entraíner ladite bascule dans le sens de la flèche B. C'est une phase de dégagement de la bascule où d'une part la corne 21 et le bord 14 peuvent glisser sur le flanc arrière 23 de la dent 24 et où d'autre part le bord 14 peut s'effacer devant la face de blocage de la dent 10.The mechanism is stopped. The second escape wheel 4 is blocked because the locking face of its tooth 10 rests on the edge 14 connecting the housings 7 and 9 of flip-flop 5. The angular excursion of flip-flop 5 is at the end of its travel since its horn 21 rests on the rear flank 23 of the tooth 24 of the first wheel exhaust 3. At this moment the balance spring is close to the end of oscillation (arrow E) or close to the end of the second half-wave of this oscillation. Tooth 13 of the plate 2 comes into contact with the tooth 12 of the rocker 5 and will cause said rocks in the direction of arrow B. It is a phase of disengaging the rocker where on the one hand the horn 21 and the edge 14 can slide on the rear flank 23 of the tooth 24 and where on the other hand the edge 14 can fade in front of the blocking face of the tooth 10.

Deuxième phase (figures 2 et 7)Second phase (Figures 2 and 7)

La bascule 5 continue sa course dans le sens de la flèche B, entraínée 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. La dent 10 de la seconde roue d'échappement a pénétré dans le logement 9 de la bascule et la phase d'impulsion 18 de la dent 10 entre en contact avec l'arête 19 de la bascule. La roue d'échappement 4 est alors entraínée 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 entraínée 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 cette bascule rencontre la face de blocage d'une dent de la première roue d'échappement.The rocker 5 continues its race in the direction of the arrow B, driven 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. Tooth 10 of the second escape wheel has entered the housing 9 of the rocker and the impulse phase 18 of tooth 10 comes into contact with the edge 19 of the scale. The escape wheel 4 is then driven in the direction of arrow F via the escape wheel 3 which turns in the direction of the arrow G driven as it is in turn by the cog whose last element 30 has been shown in FIG. 1. It is a pulse phase which throws the platform in the direction of arrow E and turns the rocker in the direction of arrow B until this rocker meets the blocking face of a tooth of the first escape wheel.

Troisième phase (figure 3 et 8)Third phase (Figures 3 and 8)

Quand la dent 13 du plateau 2 quitte la dent 11 de la bascule, la phase de blocage 17 de la dent 8 de la première roue d'échappement 3 bute contre le bord 14 de la bascule 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 soit par la corne 22 qui appuie contre le front arrière 23 de la dent 10, soit par la goupille 25 selon la solution de limitation qu'on a choisie. When tooth 13 of plate 2 leaves tooth 11 of the rocker, the phase of blocking 17 of tooth 8 of the first escape wheel 3 abuts against the edge 14 of the rocker thus blocking the first and second wheels 3 and 4. From this moment the plate 2 starts a second oscillation in the direction of arrow E. The rocker is then retained either by the horn 22 which presses against the rear front 23 of the tooth 10, either by the pin 25 according to the limiting solution that has been chosen.

Quatrième phase (figure 4)Fourth phase (Figure 4)

La situation de la bascule est la même que celle décrite ci-dessus à la différence près que sa dent 11 jouxte le bord 20 du plateau 2 pour empêcher tout renversement. Le plateau 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 scale is the same as that described above in the difference except that its tooth 11 adjoins the edge 20 of the plate 2 to prevent any reversal. The plate continues to rotate in the direction of arrow E and traverses the first alternation of its second free oscillation. Flip-flop 5 and the first and second wheels 3 and 4 are still blocked.

Cinquième phase (figure 5)Fifth phase (Figure 5)

Après avoir parcouru sa première alternance, le plateau 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 par l'action de sa dent 11 contre le bord 20 du plateau 2.After going through its first alternation, the plateau returns in direction reverse shown by arrow M and cycles through the second half of its second free oscillation. Rocker 5 always blocks the first and second wheels and is always prevented from overturning by the action of its tooth 11 against the edge 20 of the tray 2.

Sixième phase (figure 6)Sixth phase (Figure 6)

La dent 13 du plateau 2 entre en contact avec la dent 11 de la bascule 5 ce qui va entraíner 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 qui va permettre à la dent 8 de la première roue 3 de s'introduire dans le logement 7 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 blocage agissant alors sur la seconde roue d'échappement 4.The tooth 13 of the plate 2 comes into contact with the tooth 11 of the rocker 5 which will train the latter in the direction of arrow A. We find ourselves here in a situation similar to that illustrated in Figure 1, i.e. at the start of a new release phase which will allow tooth 8 of the first wheel 3 to enter the housing 7 of the rocker 5 to restart the plate 2 again. From this sixth phase a new cycle begins again similar to that which has just been described, the blocking then acting on the second escape wheel 4.

Considérations finalesFinal considerations

On a déjà indiqué plus haut que l'échappement selon l'invention prend très peu de place en hauteur puisque toutes les pièces impliquées (roues d'échappement, bascule, plateau) se trouvent à un même niveau sur un seul plan. On remarque également que ce système fait intervenir moins de pièces que celles mises en oeuvre dans l'échappement décrit à propos du document précédemment cité EP-A-1 041 459, permettant ainsi de proposer un mécanisme moins coûteux. De plus les pièces mises en jeu sont très simples ce qui assure à l'ensemble une grande sécurité de fonctionnement. We have already indicated above that the exhaust according to the invention takes very little of space in height since all the parts involved (escape wheels, scale, platform) are on the same level on a single plane. We notice also that this system involves fewer parts than those used in the exhaust described in connection with the previously cited document EP-A-1 041 459, thus making it possible to propose a less expensive mechanism. Moreover the pieces involved are very simple which gives the whole a great operational safety.

On a vu que l'impulsion sur la bascule 5 est donnée par une dent 10 d'une des roues d'échappement 4 sur une arête 19 pratiquée sur la bascule 5 (voir figure 7). La portion de dent qui donne cette impulsion est la seconde découpe 18 qui présente une forme en arc de cercle. Ceci rappelle l'échappement à détente connu de l'état de la technique et utilisé principalement en chronométrie. Cette façon de faire est très économe en énergie dépensée puisque le contact des pièces en présence est réduit à une arête frottant sur un arc de cercle. On notera par contre, que contrairement à l'échappement à détente, l'échappement selon l'invention est autodémarrant.We have seen that the impulse on flip-flop 5 is given by a tooth 10 of one of the escape wheels 4 on an edge 19 formed on the rocker 5 (see FIG. 7). The portion of tooth which gives this impulse is the second cut 18 which presents an arc shape. This recalls the known detent escapement from the state of technique and used mainly in chronometry. This is very economical in energy expended since the contact of the parts involved is reduced to an edge rubbing on an arc. Note, however, that unlike the detent escapement, the exhaust according to the invention is self-starting.

On remarquera encore que l'impulsion est communiquée au plateau 2 par une pièce intermédiaire, appelée ici bascule 5. Ceci rappelle l'échappement à ancre suisse où l'impulsion est transmise au plateau par une fourchette. L'échappement à ancre présente cependant un inconvénient, à savoir le recul de la roue d'échappement au moment du dégagement, ce recul présentant l'inconvénient de freiner le balancier et donc de consommer de l'énergie. Dans l'échappement de la présente invention il n'y a pas de recul puisque le rayon de courbure R1 du bord 14 de la bascule 5 est le même que le rayon de courbure R2 de la première découpe 17 de la dent 8 de la roue 3 (voir figure 7 et 8).It will also be noted that the impulse is communicated to the plate 2 by a intermediate piece, called here flip-flop 5. This recalls the Swiss lever escapement where the impulse is transmitted to the tray by a fork. The anchor escapement has one drawback, however, namely the retraction of the escape wheel at moment of release, this recoil having the disadvantage of braking the pendulum and therefore to consume energy. In the exhaust of the present invention there is no recoil since the radius of curvature R1 of the edge 14 of the rocker 5 is the same that the radius of curvature R2 of the first cut 17 of the tooth 8 of the wheel 3 (see Figures 7 and 8).

Il est à noter encore que le système proposé n'a pas besoin d'être lubrifié. Ceci est dû aux surfaces de contact réduites au strict minimum tant en ce qui concerne la région où se donne l'impulsion (arête 19 et découpe 18) que la région concernée par le dégagement (découpe 17 de très faible surface).It should also be noted that the proposed system does not need to be lubricated. This is due to the contact surfaces reduced to the absolute minimum both with regard to the region where the impulse is given (edge 19 and cutout 18) that the region concerned by clearance (cutout 17 of very small area).
