Description

La présente invention se rapporte au domaine de l'horlogerie, et plus particulièrement à l'affichage des informations relatives au temps. Dans la plupart des montres mécaniques ou électromécaniques, l'heure, la minute et la seconde sont affichées avec des aiguilles. Il existe également des montres dans lesquelles l'information est indiquée de manière numérique. D'autres pièces encore combinent ces informations. C'est le cas, par exemple, des montres décrites dans les documents EP 0'327'513, CH27'838/538 ou encore CH 133'500. Ces mécanismes sont agencés de manière à ce que l'aiguille des minutes avance dans un mouvement continu, alors que l'affichage de l'heure saute brusquement, à raison d'un pas chaque heure.The present invention relates to the field of watchmaking, and more particularly to the display of information relating to time. In most mechanical or electromechanical watches, hour, minute and second are displayed with hands. There are also watches in which the information is digitally indicated. Still other pieces combine this information. This is the case, for example, with the watches described in EP 0'327'513, CH27'838 / 538 or CH 133'500. These mechanisms are arranged so that the minute hand advances in a continuous movement, while the time display jumps abruptly, one step every hour.

Une telle manière de commander l'affichage numérique a pour avantage essentiel d'éviter des flottements durant le changement d'heure. Par contre, il est difficile de savoir, aux environs de l'heure, si l'affichage numérique a sauté ou non. Il existe donc ainsi des situations dans lesquelles l'information affichée manque de clarté.Such a way of controlling the digital display has the essential advantage of avoiding flutter during the change of time. On the other hand, it is difficult to know, around the hour, if the digital signage has jumped or not. There are thus situations in which the information displayed lacks clarity.

Par ailleurs, les montres mécaniques présentent aujourd'hui une image plus orientée vers l'esthétique et la sérénité, en opposition aux mouvements brusques engendrés par les moteurs pas à pas.Moreover, mechanical watches nowadays present an image more oriented towards aesthetics and serenity, as opposed to abrupt movements generated by stepping motors.

La présente invention a pour but essentiel de proposer un dispositif d'affichage permettant une lecture à la fois numérique et analogique des informations horaires, présentant un caractère esthétique marqué, tout en facilitant la lecture, même lors des changements de l'information numérique.The present invention is essentially to provide a display device for reading both digital and analog hourly information, having a marked aesthetic, while facilitating reading, even during changes in digital information.

L'invention se rapporte plus particulièrement à un dispositif d'affichage d'informations horaires muni d'un bâti, destiné à équiper un mouvement de pièce d'horlogerie comportant un rouage, et comprenant, montés sur le bâti :

  • un premier mobile, relié au rouage, agencé de manière à effectuer un mouvement cyclique en une première période et à une vitesse angulaire constante v1, et destiné à porter une aiguille affichant une première unité de temps ,
  • un disque portant des indications numériques, muni de moyens d'entraînement et destiné à afficher une deuxième unité de temps, multiple de la première unité, et
  • un deuxième mobile effectuant un mouvement cyclique de même période que le premier mobile et coopérant périodiquement avec le disque pour modifier l'information affichée.
The invention relates more particularly to a time information display device provided with a frame, intended to equip a clockwork movement comprising a gear train, and comprising, mounted on the frame:
  • a first mobile, connected to the wheel, arranged to perform a cyclic movement in a first period and at a constant angular velocity v 1 , and intended to carry a needle displaying a first unit of time,
  • a disk bearing numerical indications, provided with drive means and intended to display a second unit of time, a multiple of the first unit, and
  • a second mobile performing a cyclic movement of the same period as the first mobile and cooperating periodically with the disk to change the displayed information.

Selon l'invention, le deuxième mobile engrène avec le disque et l'entraîne dans un mouvement continu et de vitesse v2 sensiblement constante d'une position d'affichage à la suivante. De la sorte, le disque avance périodiquement dans un mouvement lent, sans saut ni à-coups, donnant l'impression qu'il glisse.According to the invention, the second mobile engages with the disk and drives it in a continuous movement and of substantially constant speed v 2 from one display position to the next. In this way, the disc moves periodically in a slow movement, without jumps or jerks, giving the impression that it slides.

Afin d'éviter toute secousse, tout en garantissant un positionnement de qualité, le disque est avantageusement muni d'encoches reliées entre elles par des secteurs de cercles coaxiaux au disque. En outre, le bâti porte un ressort sautoir disposé de manière à être engagé dans l'une des encoches lorsque le disque est arrêté et en appui contre l'un des secteurs lorsque le disque passe de l'une à l'autre de ses positions d'affichage.To avoid any shaking, while ensuring quality positioning, the disc is advantageously provided with notches interconnected by sectors of coaxial circles disk. In addition, the frame carries a jumper spring arranged to be engaged in one of the notches when the disc is stopped and bearing against one of the sectors when the disc passes from one to the other of its positions display.

Le résultat est particulièrement plaisant lorsque le disque est concentrique à l'aiguille et qu'il parcourt un angle sensiblement égal à celui parcouru par l'aiguille, la vitesse v2 étant sensiblement égale à v1, durant le temps où l'aiguille termine un cycle de son mouvement périodique. De la sorte, la vitesse angulaire du disque et de l'aiguille sont sensiblement les mêmes. L'observateur peut alors avoir l'impression que l'aiguille pousse le disque.The result is particularly pleasing when the disk is concentric with the needle and it travels at an angle substantially equal to that traveled by the needle, the speed v 2 being substantially equal to v 1 during the time when the needle ends a cycle of its periodic movement. In this way, the angular velocity of the disc and the needle are substantially the same. The observer may then have the impression that the needle pushes the disc.

Avantageusement, le mouvement cyclique de l'aiguille est un mouvement de rotation, avec une période de une heure.Advantageously, the cyclic movement of the needle is a rotational movement, with a period of one hour.

Dans le but de garantir un bon positionnement du disque, tout en assurant son entraînement dans de bonnes conditions, le bâti comporte un anneau entourant le disque, le maintenant et le positionnant par sa périphérie.In order to ensure proper positioning of the disc, while ensuring its training in good conditions, the frame has a ring surrounding the disc, maintaining it and positioning it by its periphery.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en référence au dessin dans lequel :

  • les figures 1 et 2, représentent, respectivement vu en plan et en coupe, un mouvement de montre muni d'un dispositif selon l'invention, équipé d'un cadran et d'une aiguille, et
  • les figures 3 et 4 illustrent le même mouvement, dans lequel le cadran et l'aiguille ont été retirés sur la figure 3, une partie du disque étant en outre arrachée sur la figure 4.
The invention will be better understood on reading the description which follows, given by way of example and with reference to the drawing in which:
  • FIGS. 1 and 2 show, respectively in plan and in section, a watch movement provided with a device according to the invention, equipped with a dial and a needle, and
  • FIGS. 3 and 4 illustrate the same movement in which the dial and the needle have been removed in FIG. 3, a portion of the disc being further torn off in FIG.

La figure 1 représente les moyens d'affichage d'une pièce d'horlogerie munie d'un dispositif selon l'invention, et qui comportent un cadran 10 doté d'une fenêtre 10a, un disque d'affichage 12 destiné à indiquer l'heure, partiellement apparent au travers de la fenêtre 10a et une aiguille des minutes 14.FIG. 1 represents the display means of a timepiece provided with a device according to the invention, and which comprise a dial 10 provided with a window 10a, a display disk 12 intended to indicate the hour, partially visible through the window 10a and a minute hand 14.

Comme le montre la figure 2, la pièce d'horlogerie représentée à la figure 1 comporte un mouvement 16 qui comprend notamment :

  • une structure de base 18,
  • un mobile des minutes 20 pivotant dans la structure de base 18, effectuant un tour en une heure et portant l'aiguille 14, et
  • un module complémentaire 22 portant le dispositif selon l'invention.
As shown in FIG. 2, the timepiece represented in FIG. 1 comprises a movement 16 which notably comprises:
  • a basic structure 18,
  • a minute wheel 20 pivoting in the base structure 18, making a turn in one hour and carrying the needle 14, and
  • an additional module 22 carrying the device according to the invention.

Le module 22 comprend un bâti 23 monté sur le mouvement 18, une roue 24 montée solidaire en rotation du mobile 20 et, disposés sur le bâti 23, un renvoi 26, visible seulement sur les figures 3 et 4, et un mobile d'entraînement 28.The module 22 comprises a frame 23 mounted on the movement 18, a wheel 24 mounted to rotate with the mobile 20 and, disposed on the frame 23, a return 26, visible only in Figures 3 and 4, and a drive wheel 28.

Le bâti 23 forme, à sa périphérie, un rehaut 23a définissant une noyure à l'intérieur de laquelle est disposé le disque 12.The frame 23 forms, at its periphery, a flange 23a defining a hole inside which the disc 12 is disposed.

Le mobile d'entraînement 28 comporte une roue 28a engrenant avec le renvoi 26 et un doigt 28b (figure 4) fixé rigidement sur la roue 28a et coopérant avec le disque 12 comme cela sera expliqué plus loin. La roue 28a comporte un même nombre de dents que la roue 24, de telle sorte que, étant reliées l'une à l'autre par un renvoi, elles tournent à la même vitesse angulaire et dans le même sens.The drive wheel 28 comprises a wheel 28a meshing with the reference 26 and a finger 28b (Figure 4) fixedly fixed to the wheel 28a and cooperating with the disk 12 as will be explained later. The wheel 28a has the same number of teeth as the wheel 24, so that, being connected to each other by a reference, they rotate at the same angular speed and in the same direction.

Le disque 12 comprend deux bagues superposées 30 et 32. La bague 30, supérieure, mieux visible sur la figure 3, porte les nombres de 1 à 12, destinés à afficher l'heure. Elle est munie, sur sa portion annulaire intérieure, d'encoches 30a dont la fonction sera précisée plus loin, reliées entre elles par des secteurs de cercles 30b.The disc 12 comprises two superposed rings 30 and 32. The upper ring 30, better visible in FIG. 3, bears the numbers from 1 to 12, intended to display time. It is provided on its inner annular portion with notches 30a whose function will be specified later, interconnected by sectors of circles 30b.

La bague inférieure 32, mieux visible sur la figure 4, sert de support à la bague 30. Elle est munie de douze découpes 32a formant ensemble une denture intérieure destinée à coopérer avec le doigt 28b. Elle comporte, en outre, deux trous de positionnement 32b destinés à recevoir des pieds que comporte la bague 30, pour assurer leur fixation et positionnement mutuel. Ces bagues 30 et 32 sont rendues solidaires l'une de l'autre par chassage, collage, rivetage ou par tout autre moyen connu de l'homme du métier.The lower ring 32, better visible in Figure 4, serves as a support for the ring 30. It is provided with twelve cutouts 32a together forming an internal toothing intended to cooperate with the finger 28b. It comprises, in addition, two positioning holes 32b for receiving feet that includes the ring 30, to ensure their attachment and mutual positioning. These rings 30 and 32 are secured to one another by driving, gluing, riveting or by any other means known to those skilled in the art.

Le bâti 23 porte un sautoir 34 adjacent à la bague 30 et dont l'extrémité élastique 34a est en appui contre la portion annulaire intérieure, engagée dans l'une des encoches 30a lorsque l'affichage des heures est fixe.The frame 23 carries a jumper 34 adjacent to the ring 30 and whose elastic end 34a rests against the inner annular portion, engaged in one of the slots 30a when the hours display is fixed.

A chaque tour des roues 24 et 28, le doigt 28b pénètre dans l'une des découpes 32a et entraîne en rotation le disque 12. De manière typique, l'entraînement s'effectue sur un angle de 60° environ de la roue 28, ce qui correspond à une durée de dix minutes nécessaire au changement de l'affichage de l'heure. Ainsi, durant les dix minutes qui précèdent un changement d'heure, le disque 12 se déplace lentement et sur un angle de 30°, comme poussé par l'aiguille des minutes 14.At each turn of the wheels 24 and 28, the finger 28b enters one of the cutouts 32a and rotates the disc 12. Typically, the drive is performed at an angle of about 60 ° of the wheel 28, which corresponds to a duration of ten minutes necessary to change the display of the time. Thus, during the ten minutes preceding a change of time, the disk 12 moves slowly and at an angle of 30 °, as pushed by the minute hand 14.

Lorsque le doigt 28b sort de l'encoche 32a, l'extrémité 34a du sautoir 34 se trouve dans une encoche 30a, assurant le positionnement du disque 12 entre deux changements d'heure. Cela signifie donc que le lecteur aura l'impression d'un mouvement très harmonieux, sans à-coup.When the finger 28b comes out of the notch 32a, the end 34a of the jumper 34 is in a notch 30a, ensuring the positioning of the disc 12 between two time changes. This means that the reader will have the impression of a very harmonious movement, smoothly.

Pour assurer un tel fonctionnement, il est nécessaire de parfaitement maîtriser le dispositif dans ses dimensions, pour être certain que le positionnement soit garanti, tout en évitant un saut en fin de déplacement. Ainsi, pour un disque de 30mm de diamètre, son jeu latéral dans la noyure 23b peut être de l'ordre de 0,05mm. Par ailleurs, un positionnement du disque 12 peut être assuré dans de bonnes conditions avec des encoches embrassant un angle de l'ordre de 2° en référence au centre du disque 12. L'encoche peut être de forme quelconque, mais doit pouvoir recevoir le sautoir 34 dont l'angle au sommet de l'extrémité 34a du sautoir est égal à environ 120°.To ensure such operation, it is necessary to perfectly control the device in its dimensions, to be certain that positioning is guaranteed, while avoiding a jump at the end of displacement. Thus, for a disc of 30mm in diameter, its lateral play in the hole 23b may be of the order of 0.05mm. Furthermore, a positioning of the disc 12 can be provided in good conditions with notches embracing an angle of the order of 2 ° in reference to the center of the disc 12. The notch may be of any shape, but must be able to receive the jumper 34 whose angle at the top of the end 34a of the jumper is equal to about 120 °.

Dans le dispositif tel que décrit, l'aiguille 14 et le disque 12 permettent d'afficher respectivement la minute et l'heure du temps courant. Il est également possible d'utiliser le même dispositif pour indiquer d'autres unités de temps, aussi bien relatives au temps courant qu'à des temps chronométrés.In the device as described, the needle 14 and the disc 12 make it possible to display respectively the minute and the hour of the current time. It is also possible to use the same device to indicate other time units, both for current time and timed times.

Le dispositif tel que décrit est muni d'une aiguille 14 effectuant un tour complet en une heure. Il est, bien sûr, aussi envisageable d'avoir un affichage de type rétrograde, c'est à dire dans lequel l'aiguille parcourt un angle inférieur à 360°, fréquemment 120°, puis retrouve brusquement son point de départ. Dans ce cas, le dispositif présenterait un contraste important entre l'affichage par aiguille, sautant, et un affichage numérique qui se ferait très lentement, juste avant le saut.The device as described is provided with a needle 14 performing a complete revolution in one hour. It is, of course, also possible to have a retrograde-type display, that is to say in which the needle travels at an angle less than 360 °, frequently 120 °, then abruptly finds its starting point. In this case, the device would present a significant contrast between the needle display, jumping, and a digital display that would be very slowly, just before the jump.

Ainsi, grâce aux caractéristiques que présente le dispositif selon l'invention, l'affichage du temps courant et/ou d'un temps chronométré se présente sous une forme particulièrement originale, permettant d'éviter tout saut brusque de l'affichage numérique.Thus, thanks to the characteristics of the device according to the invention, the display of the current time and / or timed time is in a particularly original form, to avoid any sudden jump of the digital display.
