Abstract

Watch movement enables a rotating cylinder to be seen through the face of the watch. A cylinder makes a twelfth of a rotation in an hour, while a rotating plate rotates once per hour. Watch movement comprises a cylinder that drives a rotating plate via a gear wheel. A bridge is mounted on the plate and its index indicates minutes. A first part of the gear wheel comprises a planet gear that rotates between the drum of the cylinder and a bridge including an hour indicator. The planet gear rotates around a fixed coil and drives a fixed pinion on the rotating plate. A second part of the gear wheel drives an escape and a regulator.

Description

La présente invention est relative à un mouvement de montre comportant un barillet délivrant une force motrice, un rouage entraíné par le barillet pour transmettre la force motrice à un échappement coopérant avec un organe régulateur et des index d'heures et de minutes, ce mouvement étant habillé par une boíte comportant une glace, une carrure et un fond.The present invention relates to a watch movement comprising a barrel delivering a driving force, a cog driven by the barrel to transmit the driving force in an exhaust cooperating with a regulating organ and indexes of hours and minutes, this movement being dressed by a box comprising a mirror, middle and bottom.

Les mouvements que l'on trouve dans une montre répondent généralement à la définition générique rappelée ci-dessus. La présente invention n'échappe pas à cette définition. Le moteur est constitué par un ressort enroulé à l'intérieur d'un barillet. Le rouage transmet la force motrice à l'échappement qui se compose ordinairement d'une roue d'échappement, d'une ancre et d'une fourchette. L'échappement entretient les oscillations de l'organe régulateur composé d'un balancier avec son spiral: c'est un oscillateur mécanique qui reçoit de l'échappement les impulsions nécessaires pour entretenir sa marche pendant un certain temps, plus une réserve de sûreté de marche. Le mouvement est complété par un système de remontoir et de mise à l'heure ainsi que par des index d'heures et de minutes. Il est habillé par une boíte.The movements found in a watch generally respond to the generic definition recalled above. The present invention does not escape this definition. The motor consists of a spring wound inside a barrel. The cog transmits the driving force to the exhaust which is composed usually an escape wheel, an anchor and a fork. The exhaust maintains the oscillations of the regulating organ composed of a pendulum with its hairspring: it is a mechanical oscillator which receives exhaust the impulses necessary to maintain its progress for a certain time, plus a market safety reserve. The movement is completed by a system of winding and setting the time as well as hour and minute indices. It is dressed by a box.

Dans une montre classique cependant, l'ensemble des organes décrits est supporté par une platine fixe et des ponts; le barillet est remonté par une tige actionnant une roue de couronne en prise sur un rochet; l'affichage du temps comporte des aiguilles d'heures et de minutes reliées par une minuterie et surmontant un cadran; la mise à l'heure est réalisée par une tige de mise à l'heure généralement confondue avec la tige de remontoir.In a classic watch, however, all of the organs described are supported by a fixed plate and bridges; the barrel is wound up by a rod operating a crown wheel engaged on a ratchet; time display has hour and minute hands linked by a timer and surmounting a dial; the time setting is carried out by a time setting rod generally confused with the winding stem.

Le mouvement de la présente invention ne comporte aucun des éléments ou caractéristiques qui viennent d'être énumérés. Il s'agit en fait d'un mouvement nouveau et original permettant de proposer des effets spéciaux et attrayants qui confèrent à la montre une facture inédite. Ainsi on n'hésitera pas à classer une telle montre dans la catégorie des montres compliquées par la haute complexité que présente son mécanisme.The movement of the present invention has none of the elements or features just listed. It’s actually a movement new and original allowing to offer special and attractive effects which give the watch an original invoice. So we will not hesitate to classify such shows in the category of watches complicated by the high complexity that presents its mechanism.

Dans ce but, et selon la présente invention, le mouvement de montre est remarquable en ce que le barillet entraíne, par une première partie du rouage, une platine tournante sur laquelle sont montrés une seconde partie du rouage, l'échappement et l'organe régulateur, le rouage étant arrangé de telle manière que le barillet tourne à raison d'un douzième de tour par heure et que la platine tournante tourne à raison d'un tour par heure. For this purpose, and according to the present invention, the watch movement is remarkable in that the barrel causes, by a first part of the train, a turntable on which a second part of the gear train is shown, the exhaust and the regulating member, the gear train being arranged in such a way that the barrel turns at a twelfth of a turn per hour and the turntable rotates at the rate of one revolution per hour.

Les caractéristiques et avantages de l'invention ressortiront maintenant de la description qui va suivre, faite en regard du dessin annexé et donnant à être explicatif, mais nullement limitatif, plusieurs formes avantageuses de réalisation de l'invention, dessins dans lesquels:

  • la figure 1 est une vue de dessus du mouvement de montre selon l'invention,
  • la figure 2 est une coupe opérée dans le mouvement de la figure 1,
  • la figure 3 est une vue schématique en plan du mouvement selon la ligne III - III de la figure 2, et
  • la figure 4 est une vue schématique en plan du mouvement selon la ligne IV - IV de la figure 2.
The characteristics and advantages of the invention will now emerge from the description which follows, given with reference to the appended drawing and giving to be explanatory, but in no way limiting, several advantageous embodiments of the invention, drawings in which:
  • FIG. 1 is a top view of the watch movement according to the invention,
  • FIG. 2 is a section made in the movement of FIG. 1,
  • FIG. 3 is a schematic plan view of the movement along line III - III of FIG. 2, and
  • FIG. 4 is a schematic plan view of the movement along the line IV - IV of FIG. 2.

Les figures 1 et 2 présentent la première en plan et la seconde en coupe le mouvement de montre selon l'invention. Ce mouvement comporte un barillet 1 qui délivre une force motrice au rouage. Le barillet 1 est composé d'un tambour 31 comportant en son sein un ressort spiral 43 dont l'extrémité extérieure est attachée à la paroi du tambour et dont l'extrémité intérieure 50 est attachée à l'arbre 12 du barillet. Le tambour 31 est fermé par un couvercle 51. Un rouage 18, 19 qui sera décrit en détail plus bas, transmet la force motrice du barillet 1 à un échappement 2 qui coopère avec un organe régulateur. 3. Le mouvement est complété par des index d'heures 40 et de minutes 41 qui apparaissent sur les figures 1, 3 et 4. Enfin le mouvement est habillé par une boíte comprenant une glace 6, une carrure 7 et un fond 8.Figures 1 and 2 show the first in plan and the second in section the watch movement according to the invention. This movement includes a barrel 1 which delivers a driving force to the cog. Barrel 1 is composed of a drum 31 comprising within it a spiral spring 43 whose outer end is attached to the wall of the drum and whose inner end 50 is attached to the shaft 12 of the barrel. The drum 31 is closed by a cover 51. A cog 18, 19 which will described in detail below, transmits the driving force of the barrel 1 to an exhaust 2 which cooperates with a regulatory body. 3. The movement is completed by indexes of hours 40 and minutes 41 which appear in FIGS. 1, 3 and 4. Finally the movement is dressed by a box comprising a crystal 6, a middle 7 and a background 8.

L'invention est remarquable et originale en ce que le barillet entraíne par une première partie 18 du rouage une platine tournante 9 sur laquelle sont montés une seconde partie 19 du rouage, l'échappement 2 et l'organe régulateur 3. Les première 18 et seconde 19 parties du rouage sont arrangées de telle manière que le barillet 1 tourne à raison d'un douzième de tour par heure et que la platine tournante 9 tourne à raison d'un tour par heure.The invention is remarkable and original in that the barrel is driven by a first part 18 of the train a rotating plate 9 on which are mounted a second part 19 of the train, the exhaust 2 and the regulating member 3. The first 18 and second 19 parts of the gear train are arranged in such a way that the barrel 1 rotates at a twelfth of an hour and that the turntable 9 rotates at one turn per hour.

Ainsi, à travers la glace 6, le porteur de la montre peut-il apercevoir une platine qui tourne au rythme des minutes ainsi qu'une seconde partie 19 du rouage, l'échappement 2 et l'organe régulateur qui tournent avec elle, cette platine entraínant en même temps l'index des minutes comme on va le voir ci-dessous. Nul doute qu'il s'agit là d'un effet esthétique remarquable qui laisse voir non seulement une aiguille des minutes tournant sur un cadran comme c'est le cas des mouvements classiques, mais encore le mécanisme qui entraíne cette aiguille et surtout l'organe régulateur qui tourne avec elle, cet organe régulateur se composant principalement d'un balancier spiral oscillant à fréquence élevée. Thus, through the crystal 6, the wearer of the watch can see a plate which turns to the rhythm of the minutes as well as a second part 19 of the train, the exhaust 2 and the regulating member which rotate with it, this driving plate at the same time the minute index as we will see below. No doubt he this is a remarkable aesthetic effect which reveals not only a needle minutes rotating on a dial as is the case with classic movements, but still the mechanism which drives this needle and especially the regulating organ which rotates with it, this regulating body consisting mainly of a pendulum spiral oscillating at high frequency.

On va décrire maintenant en détail des moyens préférés pour parvenir au résultat décrit ci-dessus.We will now describe in detail the preferred means for achieving the result described above.

La figure 3 est une vue schématique en plan du mouvement exécutée selon la ligne III - III de la figure 2. La figure 3 montre que sur le barillet 1 pivote librement une roue 10 dont l'arbre 11 est excentré par rapport à l'arbre 12 du barillet 1. Les dents 13 de la roue 10 sont en prise avec une denture intérieure 14 que présente une première couronne fixe 15 qui est solidaire de la carrure 7. Ainsi, en tournant dans le sens horaire, marqué par la flèche A, le barillet 1 entraíne-t-il la roue 10 qui roule sur la couronne 15 dans le sens antihoraires marqué par la flèche C. Les dents 13 de la roue 10 sont également en prise avec les dents 16 d'un pignon 17 qui est monté coaxialement à l'arbre 12 du barillet 1. On comprendra que le pignon 17, entraíné par la roue 10, tourne dans le sens horaire indiqué par la flèche D.Figure 3 is a schematic plan view of the movement performed according to the line III - III of Figure 2. Figure 3 shows that on the barrel 1 freely pivots a wheel 10 whose shaft 11 is eccentric relative to the shaft 12 of the barrel 1. The teeth 13 of the wheel 10 are engaged with an internal toothing 14 which has a first fixed crown 15 which is integral with the middle part 7. Thus, by turning in the direction hourly, marked by arrow A, the barrel 1 does it drive the wheel 10 which rolls on the crown 15 counterclockwise marked by arrow C. Teeth 13 of the wheel 10 are also engaged with the teeth 16 of a pinion 17 which is mounted coaxially with the shaft 12 of the barrel 1. It will be understood that the pinion 17, driven by wheel 10, turns clockwise indicated by arrow D.

Comme le montre la figure 4, qui est une vue schématique en plan du mouvement, exécutée selon la ligne IV - IV de la figure 2, le pignon 17 est solidaire de la platine tournante 9 qui tourne donc aussi dans le sens horaire signalé par la flèche E. Sur cette platine tournante 9 est montée la seconde partie 19 du rouage dont la première roue 20 est en prise avec la denture intérieure 21 que présente une seconde couronne 22. Cette seconde couronne 22 est solidaire d'une lunette de mise à l'heure 23. Comme on le voit sur la figure 2, la seconde partie 19 du rouage comporte après la première roue 20 trois mobiles 55, 56 et 57 engrenant les uns à la suite des autres. La dernière roue 24 du mobile 57 est en prise avec un pignon d'échappement 25 lui-même solidaire d'une roue d'échappement 58. Le mobile d'échappement 2 tourne librement entre la platine tournante 9 et un pont d'échappement 47. Sans que cela soit représenté au dessin, la roue d'échappement 58 peut coopérer, de manière habituelle, avec une ancre munie d'une fourchette, cette dernière transmettant des impulsions motrices à l'organe régulateur 3 dont on aperçoit le balancier 59 sur les figures 1 et 4. Le balancier 59 oscille librement entre la platine tournante 9 et un coq 46.As shown in Figure 4, which is a schematic plan view of the movement, performed along line IV - IV of Figure 2, the pinion 17 is integral of the turntable 9 which therefore also rotates clockwise indicated by the arrow E. On this turntable 9 is mounted the second part 19 of the train the first wheel 20 of which is engaged with the internal toothing 21 which has a second ring 22. This second ring 22 is integral with a focusing bezel at time 23. As seen in Figure 2, the second part 19 of the train comprises after the first wheel 20 three mobiles 55, 56 and 57 meshing with one another following the others. The last wheel 24 of the mobile 57 is engaged with a pinion exhaust 25 itself secured to an escape wheel 58. The mobile exhaust 2 rotates freely between the turntable 9 and a bridge exhaust 47. Without being shown in the drawing, the escape wheel 58 can cooperate, in the usual way, with an anchor provided with a fork, the latter transmitting motor impulses to the regulating member 3, of which sees the balance 59 in Figures 1 and 4. The balance 59 oscillates freely between the turntable 9 and a rooster 46.

Si l'on revient à la figure 3, on voit qu'on a affaire à un système d'engrenages planétaires comportant un satellite 10 roulant à l'intérieur d'une couronne fixe 15, le satellite 10 étant entraíné par le barillet 1 puis entraínant à son tour le pignon 17. Dans ces conditions, si le nombre de tours de la couronne 15 est égal à zéro et si le nombre de tours du barillet 1 est égal à un, le nombre de tours N 17 du pignon 17 sera égal à: N17=1+Z15 Z17 Z15 exprimant le nombre de dents 14 de la couronne 15 et Z17 exprimant le nombre de dents 16 du pignon 17. Avec Z15 = 176 dents et Z17 = 16 dents, on aura: N17=1+17616 =12 Ainsi quand le barillet 1 fait un tour, le pignon 17 en fait douze ou, en d'autres termes, quand le barillet 1 tourne à raison d'un douzième de tour par heure, le pignon 17 et donc la platine tournante 9 qui lui est liée, tourne à raison d'un tour par heure.If we return to Figure 3, we see that we are dealing with a planetary gear system comprising a satellite 10 rolling inside a fixed ring 15, the satellite 10 being driven by the barrel 1 then in turn driving the pinion 17. Under these conditions, if the number of turns of the crown 15 is zero and if the number of turns of the barrel 1 is equal to one, the number of turns N 17 of the pinion 17 will be equal at: NOT 17 = 1 + Z 15 Z 17 Z 15 expressing the number of teeth 14 of the crown 15 and Z 17 expressing the number of teeth 16 of the pinion 17. With Z 15 = 176 teeth and Z 17 = 16 teeth, we will have: NOT 17 = 1 + 176 16 = 12 Thus when the barrel 1 makes a turn, the pinion 17 makes twelve or, in other words, when the barrel 1 rotates at the rate of a twelfth of a turn per hour, the pinion 17 and therefore the turntable 9 which is linked, rotates at the rate of one revolution per hour.

Examinant plus en détail la coupe de la figure 2, on s'aperçoit que l'arbre 11 de la roue 10 montée sur le barillet 1 pivote d'une part dans un tambour 31 que présente le barillet 1 et d'autre part dans un premier pont 32 fixé sur ce tambour. Comme on peut le voir en figure 1, ce premier pont 32 porte une excroissance 40 qui n'est autre que l'index ou l'aiguille des heures 40 puisque, on l'a vu au paragraphe précédent, ce premier pont 32, lié au barillet 1, tourne à raison d'un douzième de tour par heure.Examining in more detail the section of Figure 2, we see that the shaft 11 of the wheel 10 mounted on the barrel 1 pivots on the one hand in a drum 31 which has the barrel 1 and on the other hand in a first bridge 32 fixed on this drum. As we can see in Figure 1, this first bridge 32 carries a projection 40 which is none other than the index or the hour hand 40 since, as we saw in the previous paragraph, this first bridge 32, linked to barrel 1, rotates at a twelfth of a turn per hour.

La figure 2 montre encore que la seconde partie 19 du rouage est prise en sandwich entre la platine tournante 9 et un second pont 33 fixé sur cette platine 9. Comme on a vu plus haut que la platine 9 tourne à raison d'un tour par heure, le second pont 33 en fera de même. La figure 1 montre ce second pont 33 selon une vue en plan. Le pont 33 porte aussi une excroissance 41 qui n'est autre que l'index ou l'aiguille des minutes puisque, lié à la platine tournante 9, il tourne à raison d'un tour par heure.Figure 2 also shows that the second part 19 of the train is taken into sandwich between the turntable 9 and a second bridge 33 fixed on this turntable 9. As we saw above that the plate 9 rotates at the rate of one revolution per hour, the second bridge 33 will do the same. Figure 1 shows this second bridge 33 according to a plan view. The bridge 33 also carries a projection 41 which is none other than the index or the minute hand since, linked to the turntable 9, it rotates at the rate of one revolution per hour.

Examinant plus avant encore la coupe montrée en figure 2, on voit que le mouvement de l'invention comporte une platine fixe 34. Cette platine 34 est traversée en son centre par une douille 35 qui a pour but de centrer le barillet 1 sur cette platine, et cela par l'intermédiaire du premier pont 32. Une pierre 36 est logée dans la douille 35. Cette pierre est traversée par un premier arbre 37. Cet arbre porte à son extrémité inférieure le pignon 17 d'entraínement de la platine tournante 9 et à son extrémité supérieure la platine tournante proprement dite. Sur le second pont 33 est chassé un second arbre 38 disposé coaxialement au premier arbre 37. Ce second arbre 38 pivote librement dans un palier 39 porté par la glace 6 qui recouvre la boíte.Examining further the section shown in Figure 2, we see that the movement of the invention comprises a fixed plate 34. This plate 34 is crossed in its center by a socket 35 which aims to center the barrel 1 on this plate, and this via the first bridge 32. A stone 36 is housed in the socket 35. This stone is crossed by a first tree 37. This tree bears at its end lower the pinion 17 for driving the turntable 9 and at its end upper the actual turntable. On the second bridge 33 is chased a second shaft 38 disposed coaxially with the first shaft 37. This second shaft 38 pivots freely in a bearing 39 carried by the glass 6 which covers the box.

La figure 2 montre aussi que le fond 8 de la boíte est solidaire de l'arbre 12 du barillet 1. Ce fond comporte des cannelures 26 qui permettent le remontage du barillet. Ainsi, comme on l'a déjà dit plus haut, le remontage n'utilise pas une tige de remontage usuelle, mais est assuré par la rotation du fond. Le fond 8 comporte encore une denture 27 qui coopère avec un cliquet de retenue 28. La figure 2 montre aussi que le fond 8 est retenu sous la boíte par une couronne 60 fixée à la carrure 7. Figure 2 also shows that the bottom 8 of the box is secured to the shaft 12 of the barrel 1. This bottom has grooves 26 which allow the winding of the barrel. Thus, as already mentioned above, the reassembly does not use a rod usual reassembly, but is ensured by the rotation of the bottom. The bottom 8 has another toothing 27 which cooperates with a retaining pawl 28. FIG. 2 shows also that the base 8 is retained under the case by a crown 60 fixed to the middle part 7.

Les figures 1, 2 et 4 montrent que la lunette 23 de mise à l'heure est une lunette tournante équipée de cannelures extérieures 29. On comprendra qu'en agissant sur cette lunette, on déplace la platine tournante 9, le pont 33 et l'index 41 qui lui est lié pour mettre à l'heure le mouvement, l'index 40 des heures étant alors aussi mis à l'heure par le déplacement de la platine tournante 9 qui entraíne à son tour et dans l'ordre le pignon 17, la roue 10, le barillet 1 et enfin le premier pont 32 sur lequel se trouve l'index 40 des heures.Figures 1, 2 and 4 show that the time setting bezel 23 is a rotating bezel fitted with external splines 29. It will be understood that in acting on this telescope, the rotating plate 9, the bridge 33 and the index 41 are moved linked to it to set the time, the 40 hour index then being also set the time by the movement of the turntable 9 which causes its turn and in order the pinion 17, the wheel 10, the barrel 1 and finally the first bridge 32 on which is the 40 hour index.

On remarquera encore que la platine fixe 34 est ajourée comme le montre bien la figure 1. Cette platine fixe peut porter des repères d'heures 61 et éventuellement de minutes. On observera que la platine fixe ajourée 34 laisse voir le tambour 31 du barillet1. Cette situation peut être mise à profit en pratiquant dans le tambour 31 une lumière 42 laissant voir le ressort 43 enfermé dans le barillet. Cette disposition permet alors d'apprécier l'état d'enroulement du ressort et de savoir ainsi si le barillet doit être remonté.It will also be noted that the fixed plate 34 is perforated as well shown Figure 1. This fixed plate can carry hour markers 61 and possibly minutes. It will be observed that the perforated fixed plate 34 reveals the drum 31 of the barrel 1. This situation can be taken advantage of by practicing in the drum 31 a light 42 showing the spring 43 enclosed in the barrel. This provision allows then to assess the state of winding of the spring and thus to know if the barrel must be traced back.

Enfin, on observera (figure 1) que le mouvement selon l'invention présente quelques analogies avec un mouvement baguette connu des horlogers où tous les mobiles sont placés en enfilade, du barillet jusqu'au balancier. Ici cependant la baguette ne comporte que la seconde partie du rouage qui tourne au rythme des minutes au lieu de rester stationnaire.Finally, it will be observed (FIG. 1) that the movement according to the invention has some analogies with a baguette movement known to watchmakers where all mobiles are placed in a row, from the barrel to the pendulum. Here however the baguette has only the second part of the cog which turns to the rhythm of minutes instead of staying stationary.
