Description

La présente invention concerne les mouvements pour montre-bracelet à affichage par aiguilles, et plus particulièrement ceux du type à complications. On appelle mouvement de montre à complications les mouvements permettant d'afficher des fonctions autres que celles de la date, qui sont généralement le quantième, le jour, l'heure, la minute et la seconde. C'est le cas notamment des montres connues sous le nom de chronographe et qui permettent de faire démarrer un compteur de temps en un instant donné et de l'arrêter, de le faire repartir ou de le remettre à zéro en n'importe quel moment.The present invention relates to movements for wristwatch with display by needles, and more particularly those of the type with complications. Complicated movements are movements that display functions other than the date, which are usually the date, the day, the hour, the minute and the second. This is particularly the case of watches known as the chronograph and which make it possible to start a time counter at a given moment and to stop it, to restart it or to reset it at any time .

Les montres réalisées au moyen de ces mouvements comportent, de manière classique, un affichage de l'heure et de la minute du temps courant au moyen d'aiguilles disposées au centre du cadran. L'aiguille de secondes du chronographe leur est concentrique. D'autres informations sont affichées au moyen d'aiguilles. Il s'agit généralement de la seconde du temps courant, de la minute et de l'heure chronométrée. Elles sont affichées au moyen de petites aiguilles dont l'axe de pivotement se trouve généralement à une distance de l'axe central sensiblement égale à la moitié du rayon du cadran. Si le cadran n'est pas rond, cette distance est sensiblement égale à la moitié du rayon d'un cercle inscrit dans le pourtour du cadran.The watches made using these movements comprise, in a conventional manner, a display of the hour and minute of the current time by means of needles arranged in the center of the dial. The seconds hand of the chronograph is concentric to them. Other information is displayed by means of needles. This is usually the second of the current time, the minute and the timed time. They are displayed by means of small needles whose pivot axis is generally at a distance from the central axis substantially equal to half the radius of the dial. If the dial is not round, this distance is substantially equal to half the radius of a circle inscribed in the periphery of the dial.

Le cadran de la montre comporte, ainsi, jusqu'à quatre petits cadrans disposés généralement à midi, 3, 6 et 9 heures. Des montres de ce type sont illustrées en pages 283 et 285 du catalogue d'oeuvres choisies du Musée International d'Horlogerie, La Chaux-de-Fonds 1999 ISBN 2-940088-07-1. On constate que pratiquement toute la surface apparente est occupée par l'affichage des différentes fonctions. Il en résulte une lourdeur qui nuit à l'esthétique de la montre.The dial of the watch thus comprises up to four small dials arranged generally at noon, 3, 6 and 9 o'clock. Watches of this type are illustrated on pages 283 and 285 of the catalog of selected works of the International Watchmaking Museum, La Chaux-de-Fonds 1999 ISBN 2-940088-07-1. It can be seen that practically all the apparent surface is occupied by the display of the different functions. This results in a heaviness that affects the aesthetics of the watch.

Par ailleurs, la lecture des informations affichées nécessite une attention très particulière, puisque le regard doit effectuer un mouvement tournant pour lire les quatre petites aiguilles.Moreover, the reading of the displayed information requires very particular attention, since the eye must make a turning movement to read the four small needles.

Le but de la présente invention est de permettre la réalisation de montres comportant un nombre important de complications, offrant un affichage dont la lecture est agréable et qui évite de surcharger le cadran.The object of the present invention is to allow the production of watches with a large number of complications, providing a display whose reading is pleasant and avoids overloading the dial.

Le mouvement pour montre-bracelet selon l'invention est donc à affichage par aiguilles, comportant des mobiles, destinés à recevoir des aiguilles des heures et des minutes du temps courant, montés pivotant autour d'un premier axe disposé sensiblement au centre du mouvement et quatre mobiles destinés à recevoir des aiguilles pour afficher des fonctions complémentaires.The wristwatch movement according to the invention is therefore a needle display, comprising mobiles, intended to receive hour and minute hands of the current time, mounted to pivot about a first axis disposed substantially at the center of the movement and four mobiles for receiving needles to display complementary functions.

Il est caractérisé en ce que les quatre mobiles sont montés pivotant sur le mouvement autour de deuxième, troisième, quatrième et cinquième axes disposés sur une droite qui leur est perpendiculaire, les deuxième et cinquième axes formant avec le premier axe les sommets d'un triangle isocèle dont la base repose sur ladite droite, l'angle au sommet étant compris entre 120° et 180°.It is characterized in that the four mobiles are mounted pivoting on the movement about second, third, fourth and fifth axes arranged on a line perpendicular thereto, the second and fifth axes forming with the first axis the vertices of a triangle. isosceles whose base rests on said straight line, the apex angle being between 120 ° and 180 °.

Il a certes déjà été représenté des arbres de mobiles d'horlogerie alignés sur une droite. Ainsi, le document EP-A-0 389 440 comporte un schéma-bloc de mouvement de montre muni de quatre aiguilles. Sur ce schéma, les aiguilles sont représentées sur une ligne. Par contre sur la figure représentant la montre dans sa structure, les axes des arbres portant les aiguilles sont disposés concentriquement au centre du mouvement.It has certainly already been represented by clockwork trees aligned on a straight line. Thus, the document EP-A-0 389 440 has a watch movement block diagram with four hands. In this diagram, the needles are represented on a line. On the other hand, in the figure representing the watch in its structure, the axes of the shafts carrying the needles are arranged concentrically in the center of the movement.

Le document US-A-5 739 647 se rapporte à un transducteur destiné à équiper une montre et comportant plusieurs rotors, certains modes de réalisation les montrant alignés. Les rouages entraînés par ces rotors ne sont, toutefois, pas représentés.The document US-A-5,739,647 relates to a transducer for equipping a watch and having several rotors, some embodiments showing them aligned. The workings driven by these rotors are, however, not represented.

De manière avantageuse, la droite passant par les deuxième à cinquième axes est disposée en dessous d'une ligne passant de 3 à 9 heures, par le centre du mouvement.Advantageously, the line passing through the second to fifth axes is disposed below a line passing from 3 to 9 hours, by the center of the movement.

L'expérience a montré que, de manière avantageuse, l'angle au sommet est sensiblement égal à 140°.Experience has shown that, advantageously, the apex angle is substantially equal to 140 °.

Une solution particulièrement attrayante se rapporte à un mouvement du type chronographe, qui comporte un mobile destiné à porter une aiguille de secondes du temps chronométré concentrique aux aiguilles d'heures et de minutes. Parmi les quatre mobiles dont les axes sont disposés en ligne, trois d'entre eux sont destinés à afficher respectivement la minute et l'heure du temps chronométré et la seconde du temps courant. Le quatrième mobile peut être destiné à afficher les 24 heures du jour.A particularly attractive solution relates to a movement of the chronograph type, which comprises a mobile intended to carry a second hand of concentric timed time to the hour and minute hands. Of the four mobiles whose axes are arranged in line, three of them are intended to display respectively the minute and hour of the timed time and the second of the current time. The fourth mobile can be intended to display the 24 hours of the day.

Il est bien connu que la construction et l'industrialisation d'un mouvement de montre, et à plus forte raison d'un chronographe, nécessite un fort investissement en temps et en argent. Aussi, afin de permettre une application rapide et économique de l'objet de l'invention, il est avantageux que le mouvement comporte une platine destinée à porter ses différents composants et que les quatre mobiles, dont les axes sont alignés, sont disposés sur un module, lui-même monté sur la platine, chacun des quatre mobiles étant relié cinématiquement à un mobile pivotant dans la platine.It is well known that the construction and industrialization of a watch movement, and even more so of a chronograph, requires a large investment of time and money. Also, to allow a rapid and economical application of the object of the invention, it is advantageous that the movement comprises a plate intended to carry its various components and that the four mobiles, whose axes are aligned, are arranged on a module, itself mounted on the plate, each of the four mobiles being kinematically connected to a mobile pivoting in the plate.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel:

  1. 1. La figure 1 représente une montre munie d'un mouvement selon l'invention;
  2. 2. Les figures 2 et 3 sont respectivement des vues de côté et de dessus du mouvement selon l'invention; et
  3. 3. Les figures 4 à 7 montrent, en coupe, des rouages spécifiques à ce mouvement.
Other advantages and features of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  1. 1. The figure 1 represents a watch provided with a movement according to the invention;
  2. 2. The Figures 2 and 3 are respectively side and top views of the movement according to the invention; and
  3. 3. The Figures 4 to 7 show, in section, the wheels specific to this movement.

La montre, représentée à la figure 1, est de type chronographe. Elle comporte, de manière classique, une boîte 10 à l'intérieur de laquelle est logé un mouvement 12, non visible sur la figure 1 et qui ne sera décrit qu'en référence aux figures 2 et 3.The watch, represented in figure 1 , is chronograph type. It comprises, in a conventional manner, a box 10 inside which is housed a movement 12, not visible on the figure 1 and which will only be described with reference to Figures 2 and 3 .

Le mouvement porte un cadran 14 au devant duquel sont disposées des aiguilles destinées à l'affichage des informations horaires courantes, soit une aiguille d'heures 16 effectuant un tour en 12 heures, une aiguille d'heures 18 effectuant un tour en 24 heures, une aiguille des minutes 20 et une aiguille des secondes 22. Cet affichage est complété par l'indication du quantième 24, qui apparaît au travers d'un guichet 26 pratiqué à midi dans le cadran 14. Les aiguilles des heures 16 et des minutes 20 sont disposées au centre du cadran 14 et tournent autour d'un axe A-A perpendiculaire au plan de la feuille sur la figure 1.The movement carries a dial 14 in front of which are arranged needles for the display of the current hourly information, namely an hour hand 16 performing a turn in 12 hours, an hour hand 18 performing a turn in 24 hours, a minute hand 20 and a second hand 22. This display is completed by the indication of the date 24, which appears through a window 26 practiced at noon in the dial 14. The hour hands 16 and minutes 20 are arranged at the center of the dial 14 and rotate about an axis AA perpendicular to the plane of the sheet on the figure 1 .

La montre comporte, en outre, trois aiguilles 27, 28 et 30 de chronographe, affichant respectivement les secondes, les minutes et les heures des temps chronométrés.The watch further comprises three chronograph hands 27, 28 and 30, respectively displaying the seconds, minutes and hours of the timed times.

Pour assurer la commande de la montre, l'utilisateur dispose d'une couronne 32, placée à 3 heures et qui permet d'assurer la mise à l'heure et, dans les montres mécaniques, le remontage du ressort-moteur. En outre, deux poussoirs 34 et 36, disposés respectivement à 2 et 4 heures, permettent, de manière classique, la commande des fonctions du chronographe.To ensure the control of the watch, the user has a ring 32, placed at 3 o'clock and which ensures the time setting and, in mechanical watches, the winding of the mainspring. In addition, two pushers 34 and 36, respectively arranged at 2 and 4 hours, allow, in a conventional manner, the control of the functions of the chronograph.

Comme le montre très clairement la figure 1, les aiguilles 28, 30, 18 et 22 pivotent respectivement autour d'axes B-B, C-C, D-D et E-E qui, sur la figure 1, sont perpendiculaires au plan du dessin et disposées en ligne, de sorte qu'il est possible de faire passer une droite X-X par les points d'intersection B, C, D, E de ces axes avec le plan du dessin. De plus, si l'on relie les points extrêmes B et E, correspondant aux axes B-B et E-E, avec le point A correspondant à l'axe A-A, on définit un triangle isocèle dont l'angle au sommet A est sensiblement égal à 140°. Cette solution permet un affichage tout à fait lisible tout en conférant au cadran une certaine "assise" esthétique due au fait que les structures graphiques disposées sur le cadran et définissant les échelles des aiguilles 28, 30, 18 et 22, sont disposées en dessous de l'axe A-A, soit sensiblement sur une droite passant entre 3 ½ heures et 8 ½ heures.As is very clearly shown figure 1 , the needles 28, 30, 18 and 22 pivot respectively about axes BB, CC, DD and EE which, on the figure 1 , are perpendicular to the plane of the drawing and arranged in line, so that it It is possible to pass a line XX by the points of intersection B, C, D, E of these axes with the plane of the drawing. Moreover, if we connect the extreme points B and E, corresponding to the axes BB and EE, with the point A corresponding to the axis AA, we define an isosceles triangle whose angle at the vertex A is substantially equal to 140 °. This solution allows a completely readable display while giving the dial a certain "seating" aesthetic due to the fact that the graphic structures arranged on the dial and defining the scales of the needles 28, 30, 18 and 22, are arranged below the axis AA, substantially on a line passing between 3 ½ hours and 8 ½ hours.

Ces considérations esthétiques sont particulièrement valables pour les montres dont le cadran est rond. En utilisant une boîte et un cadran présentant une forme différente, le problème peut se poser en d'autres termes. Il a toutefois été constaté que, dans la plupart des cas, l'angle au sommet est compris entre 120 et 180°.These aesthetic considerations are particularly valid for watches with a round dial. By using a box and a dial having a different shape, the problem may arise in other words. It has been found, however, that in most cases the apex angle is between 120 and 180 °.

En d'autres termes, dès l'instant où les axes B-B et E-E dépassent des secteurs définis par les lignes reliant 4 heures à 10 heures d'une part, et 2 heures à 8 heures d'autre part, la place disponible diminue de manière telle que les affichages sont trop réduits pour permettre une lecture dans des conditions favorables.In other words, as soon as the axes BB and EE exceed sectors defined by the lines connecting 4 hours to 10 hours on the one hand, and 2 hours to 8 hours on the other hand, the available space decreases by such that the displays are too small to allow reading under favorable conditions.

Pour bien comprendre comment il est possible de réaliser un affichage présentant les caractéristiques énoncées plus haut, il faut se référer aux figures 2 à 7 qui représentent les parties essentielles du mouvement 12 en rapport avec l'invention.To understand how it is possible to make a display with the characteristics listed above, we must refer to Figures 2 to 7 which represent the essential parts of the movement 12 in connection with the invention.

Le mouvement 12 comporte une platine 38 sur laquelle la plupart des composants de la montre sont montés, notamment en son centre, un pignon de secondes de chronographe 40, une chaussée 42 et une roue à canon 44. Ces trois mobiles, qui portent respectivement les aiguilles 26, 20 et 16 pivotent autour de l'axe A-A.The movement 12 comprises a plate 38 on which most of the components of the watch are mounted, in particular at its center, a chronograph seconds pinion 40, a roadway 42 and a gun wheel 44. three mobiles, which carry respectively the needles 26, 20 and 16 pivot about the axis AA.

Trois autres mobiles, munis chacun d'un tigeron identifié par la lettre a, et d'une roue de renvoi identifiée par la lettre b, portant respectivement les références 46, 48 et 50 effectuent respectivement un tour en 30 minutes de temps chronométré, 12 heures de temps chronométré et 60 secondes de temps courant (figure 3).Three other mobiles, each equipped with a tigeron identified by the letter a , and a reference wheel identified by the letter b, respectively bearing the references 46, 48 and 50 respectively perform a lap in 30 minutes timed, 12 hours of time and 60 seconds of current time ( figure 3 ).

La platine 38 porte, en outre, un module 52 formé d'une plaque de base 54 et d'un pont 56, fixés rigidement l'un à l'autre au moyen de vis 57. Le module 52 porte, intercalés entre la plaque 54 et le pont 56, trois rouages de renvoi 58, 60 et 62 et un rouage démultiplicateur 64.The plate 38 carries, in addition, a module 52 formed of a base plate 54 and a bridge 56, fixed rigidly to one another by means of screws 57. The module 52 carries, interposed between the plate 54 and the bridge 56, three gear wheels 58, 60 and 62 and a gear wheel 64.

Le rouage 58, représenté en coupe sur la figure 5, est en prise avec la roue de renvoi 46b. Il comporte un renvoi 58a et une roue 58b, celle-ci ayant le même nombre de dents que la roue 46b, de manière que la roue 58b tourne dans le même sens et à la même vitesse que la roue 46b. La roue 58b comporte un tigeron 58c destiné à recevoir l'aiguille des minutes de temps chronométré 28.The gear train 58, shown in section on the figure 5 is engaged with the return wheel 46b. It comprises a reference 58a and a wheel 58b, the latter having the same number of teeth as the wheel 46b, so that the wheel 58b rotates in the same direction and at the same speed as the wheel 46b. The wheel 58b includes a rod 58c intended to receive the minute hand of timed time 28.

Le rouage 60, représenté en coupe sur la figure 6, est en prise avec la roue de renvoi 48b. Il comporte un renvoi 60a et une roue 60b, celle-ci ayant le même nombre de dents que la roue 48b, de manière que la roue 60b tourne dans le même sens et à la même vitesse que la roue 48b. La roue 60b comporte un tigeron 60c destiné à recevoir l'aiguille des heures de temps chronométré 30.The gear train 60, shown in section on the figure 6 is engaged with the return wheel 48b. It comprises a reference 60a and a wheel 60b, the latter having the same number of teeth as the wheel 48b, so that the wheel 60b rotates in the same direction and at the same speed as the wheel 48b. The wheel 60b includes a tigger 60c for receiving the hour hand of timed time 30.

Le rouage 62, représenté en coupe sur la figure 7, est en prise avec la roue de renvoi 50b. Il comporte un renvoi 62a et une roue 62b, celle-ci ayant le même nombre de dents que la roue 50b, de manière que la roue 62b tourne dans le même sens et à la même vitesse que la roue 50b. La roue 62b comporte un tigeron 62c destiné à recevoir l'aiguille des secondes de temps courant 22.The gear train 62, shown in section on the figure 7 is engaged with the return wheel 50b. It comprises a reference 62a and a wheel 62b, the latter having the same number of teeth as the wheel 50b, so that the wheel 62b rotates in the same direction and at the same speed as the wheel 50b. The wheel 62b includes a rod 62c intended to receive the seconds hand of current time 22.

Enfin, le rouage démultiplicateur 64, représenté en coupe sur la figure 4, engrène avec un pignon 44a de la roue à canon 44. Il comporte un renvoi 64a et une roue 64b dont le nombre de dents est égal au double de celui du pignon 44a, de manière que la roue 64b tourne dans le même sens et deux fois plus lentement que la roue à canon, c'est-à-dire que l'aiguille des heures 16. La roue 64b comporte un tigeron 64c destiné à recevoir l'aiguille des heures de temps courant 18, effectuant un tour en 24 heures.Finally, the gear train 64, shown in section on the figure 4 , it meshes with a pinion 44a of the gun wheel 44. It comprises a return 64a and a wheel 64b whose number of teeth is twice that of the pinion 44a, so that the wheel 64b rotates in the same direction and two time more slowly than the barrel wheel, that is to say that the hour hand 16. The wheel 64b has a rod 64c for receiving the hour hand of current time 18, making a turn in 24 hours .

Comme on peut le voir tout particulièrement sur la figure 2, les axes de pivotement B, C, D et E des roues 58b, 60b, 64b et 62b sont disposées dans cet ordre, sur la ligne horizontale X - X, qui est légèrement décalée vers le bas par rapport au centre du mouvement.As can be seen especially in the figure 2 the pivot axes B, C, D and E of the wheels 58b, 60b, 64b and 62b are arranged in this order on the horizontal line X - X, which is slightly downward with respect to the center of the movement.

Le module 52 est positionné, de manière classique, au moyen de pieds 66 solidaires de la plaque de base et engagés dans des trous de la platine 38. Il est fixé, par exemple au moyen de vis, qui n'ont pas été représentées au dessin.The module 52 is positioned, in a conventional manner, by means of feet 66 integral with the base plate and engaged in holes in the plate 38. It is fixed, for example by means of screws, which have not been represented at drawing.

Il va de son que le mouvement selon l'invention peut-faire l'objet de nombreuses variantes, sans pour autant sortir du cadre de l'invention définie par les revendications. Ainsi, les quatre mobiles alignés pourraient porter des aiguilles assurant l'affichage de fonctions autres que celles décrites.It is understood that the movement according to the invention can be the subject of numerous variants without departing from the scope of the invention defined by the claims. Thus, the four aligned mobiles could carry needles ensuring the display of functions other than those described.

Il serait également possible de placer verticalement la droite sur laquelle les quatre axes sont alignés, par exemple pour les pays dans lesquels la lecture se fait de haut en bas.It would also be possible to place vertically the line on which the four axes are aligned, for example for the countries in which the reading is done from top to bottom.

Claims (7)
