Description

La présente invention se rapporte aux mécanismes de quantième. Elle concerne plus particulièrement un mécanisme du type à grand guichet, grâce auquel la lecture de la date est facilitée.The present invention relates to date mechanisms. She more particularly a mechanism of the type with a large window, thanks to which the reading of the date is facilitated.

Un tel mécanisme est décrit dans le document WO 98/50829. Il comporte un mobile de commande annulaire effectuant un tour par mois et muni de première et deuxième dentures, lesquelles entraínent deux mobiles d'affichage portant respectivement les chiffres des unités et des dizaines. Le mobile de commande est disposé concentriquement aux aiguilles. Les mobiles d'affichage sont disposés côte à côte, à l'intérieur de l'anneau que forme le mobile de commande, et décentrés par rapport à ce dernier. Le mobile de commande peut être réalisé en modifiant un disque de quantième classique. Il est, de la sorte, possible de munir un calibre existant d'un affichage à grand guichet, avec un minimum de modifications. Une telle solution implique une date à midi ou à 6 heures, dans la partie médiane du cadran, avec des dimensions du guichet relativement modestes.Such a mechanism is described in WO 98/50829. It has a mobile ring control unit, making one turn per month and equipped with first and second teeth, which cause two movable displaying respectively the numbers of the units and the tens. The Mobile control is arranged concentrically to the needles. The mobile displays are arranged side by side, inside the ring that forms the control mobile, and off-center with respect to the latter. The Mobile control can be achieved by modifying a date disc classic. It is therefore possible to provide an existing template with a Big ticket display, with a minimum of modifications. Such a solution involves a date at noon or 6 o'clock in the middle part of dial, with relatively modest window dimensions.

Le document WO 99/13383 concerne un mécanisme comportant également un mobile de commande effectuant un tour par mois. Ce mobile assure, en outre, l'affichage des unités. Il entraíne un mobile d'affichage des dizaines superposé au disque des unités et muni de découpes au travers desquelles apparaissent les chiffres des unités. Les mobiles de commande et d'affichage des dizaines sont décentrés l'un par rapport à l'autre. Cette solution est encore plus simple que la précédente. Ici aussi, l'affichage doit se faire à 6 heures ou à midi, et la dimension maximale des chiffres affichés reste modeste.WO 99/13383 relates to a mechanism also comprising a control mobile performing one turn per month. This mobile ensures, in in addition, the display units. It drives a display mobile dozens superimposed on the disk of the units and provided with cuts through which the numbers of the units appear. The control and display mobiles dozens are off-center with respect to each other. This solution is even simpler than the previous one. Here too, the display should be 6 hours or noon, and the maximum dimension of the displayed figures remains modest.

Une autre solution est décrite dans le document EP 0 529 191, faisant appel à des mobiles d'affichage des unités et des dizaines qui peuvent être concentriques. Ceux-ci sont entraínés par un mobile de commande, décentré par rapport au centre du mouvement et des mobiles d'affichage, qui effectue un tour par mois. Les deux mobiles d'affichage sont munis de disques superposés dont le diamètre est sensiblement égal au rayon du mouvement. Cette solution permet d'avoir un affichage de très grande dimension, mais implique une construction spécifique. Ses organes constitutifs sont décalés par rapport au centre du mouvement.Another solution is described in document EP 0 529 191, using mobile display units and tens that can be concentric. These are driven by a control wheel, off-center relative to the center of movement and display mobiles, which performs one round a month. Both display mobiles have disks superimposed whose diameter is substantially equal to the radius of the movement. This solution makes it possible to have a very large display, but involves a specific construction. Its constituent organs are staggered relative to the center of the movement.

Le but de la présente invention est de pallier ces inconvénients. Selon l'invention, le mécanisme de quantième comporte :

  • un mobile de commande effectuant un tour par mois et muni de première et deuxième dentures,
  • des premier et deuxième trains d'engrenages respectivement en prise avec les première et deuxième dentures,
  • un premier mobile d'affichage entraíné par le premier train d'engrenages et portant les chiffres des unités du quantième, et
  • un deuxième mobile d'affichage entraíné par le deuxième train d'engrenages et portant les chiffres des dizaines du quantième.
The object of the present invention is to overcome these disadvantages. According to the invention, the date mechanism comprises:
  • a control wheel performing one turn per month and provided with first and second teeth,
  • first and second gear trains respectively engaged with the first and second teeth,
  • a first display unit driven by the first gear train and bearing the numbers of the date units, and
  • a second mobile display driven by the second gear and carrying the numbers of the tens of the date.

Il est caractérisé en ce que les mobiles de commande et d'affichage sont concentriques les uns aux autres.It is characterized in that the control and display mobiles are concentric to each other.

Ce mécanisme est avantageusement destiné à équiper une pièce d'horlogerie munie d'un affichage par aiguilles pivotant au centre du mouvement. Dans un mode de réalisation particulièrement intéressant, les mobiles de commande et d'affichage sont concentriques au mouvement. Il est, de la sorte, possible de réaliser un affichage de grande dimension sur la base d'un calibre existant, le disque de quantième modifié pouvant assurer la fonction de mobile de commande.This mechanism is advantageously intended to equip a timepiece equipped with a pivoting needle display in the center of the movement. In one particularly interesting embodiment, the control mobiles and display are concentric to movement. It is thus possible to make a large display on the basis of an existing template, the modified date disc capable of performing the mobile function of ordered.

Dans un premier mode de réalisation, le deuxième train d'engrenages est agencé de manière à ce que le deuxième mobile d'affichage, affichant les dizaines, effectue quatre pas par tour. Ce mobile d'affichage est muni d'un disque portant les indications « 0 » ou « rien », « 1 », « 2 » et « 3 ».In a first embodiment, the second gear train is arranged so that the second display mobile, displaying the dozens, takes four steps per turn. This mobile display is equipped with a disc marked "0" or "nothing", "1", "2" and "3".

Dans un deuxième mode de réalisation, le deuxième train d'engrenages est agencé de manière à ce que le deuxième mobile d'affichage, affichant les dizaines, effectue cinq pas par tour. Ce mobile d'affichage est muni d'un disque portant les indications « 0 » ou « rien », « 1 », « 2 », « 3 » et « 31 ».In a second embodiment, the second gear train is arranged so that the second display mobile, displaying the dozens, takes five steps per turn. This mobile display is equipped with a disc marked "0" or "nothing", "1", "2", "3" and "31".

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

  • La figure 1 représente une montre munie d'un mécanisme selon l'invention ;
  • Les figures 2a et 2b sont des vues de dessus d'un mécanisme selon l'invention, certaines parties étant arrachées sur la figure 2b pour voir le mécanisme disposé en dessous des moyens d'affichage ;
  • Les figures 3a et 3b montrent, respectivement vu en coupe selon les lignes AA et BB, le mouvement de la figure 2 ; et
  • Les figures 4 et 5 montrent, pour deux modes de réalisation, la structure des moyens de commandé de l'affichage des dates.
Other advantages and features of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • FIG. 1 represents a watch provided with a mechanism according to the invention;
  • Figures 2a and 2b are top views of a mechanism according to the invention, some parts being torn off in Figure 2b to see the mechanism disposed below the display means;
  • Figures 3a and 3b show, respectively seen in section along lines AA and BB, the movement of Figure 2; and
  • Figures 4 and 5 show, for two embodiments, the structure of the control means of the dates display.

La montre représentée sur la figure 1 comporte, de manière classique, une boíte 10, un cadran 12 muni d'un guichet 14, un affichage de la date 16 et des aiguilles des heures 18, des minutes 20 et des secondes 22. L'affichage de la date 16 ainsi que les aiguilles 18, 20 et 22 sont mus par un mouvement monté dans le logement que forme la boíte 10 et qui sera partiellement décrit en référence aux figures 2 et 3. Une couronne de mise à l'heure 24 permet de corriger les informations affichées.The watch shown in FIG. 1 comprises, in a conventional manner, a box 10, a dial 12 provided with a window 14, a display of the date 16 and 18, 20 and 22 hour hands. The display of the date 16 and needles 18, 20 and 22 are driven by a mounted movement in the housing that forms the box 10 and which will be partially described in 2 and 3. A time-setting ring 24 makes it possible to correct the information displayed.

Le mouvement, représenté en plan aux figures 2a et 2b, est montré en coupe respectivement selon les lignes AA et BB sur les figures 3a et 3b. Il comprend une structure de base 26, schématiquement illustrée et formée d'un bâti portant une source d'énergie, une base de temps, un rouage tournant en synchronisme avec la base de temps, et des mécanismes, de mise à l'heure commandé par la couronne 24, et de quantième entraínant l'affichage 16. Le rouage comporte des mobiles disposés au centre du mouvement et munis d'arbres 28, 30 et 32 destinés à porter respectivement les aiguilles 18, 20 et 22. La structure de base 26 porte un module 34 de quantième qui sera décrit de manière plus détaillée ci-après.The movement, shown in plan in FIGS. 2a and 2b, is shown in section respectively along the lines AA and BB in Figures 3a and 3b. He understands a basic structure 26, schematically illustrated and formed of a frame carrying a source of energy, a time base, a cog wheel turning synchronism with the time base, and mechanisms, setting time controlled by the crown 24, and the date of the month causing the display 16. The cogwheel consists of movers arranged at the center of the movement and equipped trees 28, 30 and 32 for respectively carrying the needles 18, 20 and 22. The basic structure 26 carries a date module 34 which will be described in more detail below.

Le mécanisme de quantième de la structure de base entraíne, de manière connue, un disque tenant lieu de mobile de commande 36 et faisant un tour en un mois. Il est muni de deux dentures 36a et 36b formées de goupilles disposées perpendiculairement au plan du disque.The date mechanism of the basic structure leads, in a manner known, a disk in place of mobile control 36 and making a tour in a month. It is provided with two toothings 36a and 36b formed of pins arranged perpendicularly to the plane of the disc.

Le module 34 comprend une plaque 38 montée sur le bâti de la structure de base 26 au moyen de vis non représentées et s'étendant sur l'essentiel de sa surface. La plaque 38 porte deux trains d'engrenages 40 (figure 3b) et 42 (figure 3a), respectivement en prise avec les dentures 36a et 36b. La plaque 38 est munie, dans sa partie centrale, d'un canon 38a concentrique aux arbres 28, 30 et 32 et les entourant.The module 34 comprises a plate 38 mounted on the frame of the structure of base 26 by means of screws not shown and extending over most of its area. Plate 38 carries two gear trains 40 (FIG. 3b) and 42 (Figure 3a) respectively engaged with the teeth 36a and 36b. The plaque 38 is provided, in its central part, with a concentric barrel 38a trees 28, 30 and 32 and surrounding them.

Deux mobiles d'affichage 44 et 46 sont montés pivotant sur le canon 38a. Le mobile 44 comporte un disque 44a, qui porte les chiffres des unités du quantième, et un pignon 44b en prise avec le train d'engrenages 40 et sur lequel est fixé le disque 44a. Le mobile 46 est monté pivotant sur le mobile 44. Il comprend un disque 46a, portant les chiffres des dizaines, et un pignon 46b en prise avec le train d'engrenages 42, et sur lequel est fixé le disque 46a.Two display mobiles 44 and 46 are pivotally mounted on the barrel 38a. The mobile 44 comprises a disk 44a, which carries the numbers of the units of the date, and a pinion 44b engaged with the gear train 40 and on which is fixed the disk 44a. The mobile 46 is pivotally mounted on the mobile 44. It comprises a disk 46a, bearing the digits of the tens, and a pinion 46b engaged with the gear train 42, and on which is fixed the disc 46a.

Le train d'engrenages 40 comporte :

  • une roue 40a, comprenant une planche 40b munie de quatre découpes en prise avec la denture 36a et un pignon 40c, et
  • un renvoi 40d transmettant le mouvement du pignon 40c vers le pignon 44b du mobile 44.
The gear train 40 comprises:
  • a wheel 40a, comprising a board 40b provided with four cutouts in engagement with the toothing 36a and a pinion 40c, and
  • a reference 40d transmitting the movement of the pinion 40c to the pinion 44b of the mobile 44.

Les nombres de dents des pignons 44b et 40c sont choisis de manière à ce que, pour un quart de tour du pignon 40c, le pignon 44b fasse un dixième de tour. De la sorte, à chaque pas du mobile de commande 36, et dans la mesure où la denture 36a comporte une goupille, la roue 40a fait un quart de tour et le pignon 44b un dixième de tour, ce qui correspond au passage d'un chiffre des unités au suivant. The numbers of teeth of the pinions 44b and 40c are chosen so that that, for a quarter turn of the pinion 40c, the pinion 44b makes a tenth of tower. In this way, at each step of the control wheel 36, and in the as the toothing 36a has a pin, the wheel 40a makes a quarter of turn and pinion 44b a tenth of a turn, which corresponds to the passage of a number of units to the next.

Le train d'engrenages 42 comporte :

  • une roue 42a, comprenant une planche 42b munie de trois découpes en prise avec la denture 36b et un pignon 42c, et
  • un renvoi 42d transmettant le mouvement du pignon 42c vers le pignon 46b du mobile 46.
The gear train 42 comprises:
  • a wheel 42a, comprising a board 42b provided with three cutouts in engagement with the toothing 36b and a pinion 42c, and
  • a reference 42d transmitting the movement of the pinion 42c to the pinion 46b of the mobile 46.

Les nombres de dents des pignons 46b et 42c sont choisis de manière à ce que, pour un tiers de tour du pignon 42c, le pignon 44b fasse un quart de tour. De la sorte, à chaque pas du mobile de commande 36, et dans la mesure où la denture 36b comporte une goupille, la roue 42a fait un tiers de tour et le pignon 46b un quart de tour, ce qui correspond au passage d'un chiffre des dizaines au suivant.The tooth numbers of the pinions 46b and 42c are chosen so that that for a third turn of the pinion 42c, the pinion 44b makes a quarter of tower. In this way, at each step of the control wheel 36, and in the as the toothing 36b has a pin, the wheel 42a is one third of turn and pinion 46b a quarter turn, which corresponds to the passage of a numbers from tens to the next.

Comme on peut le voir plus particulièrement sur les figures 3a et 3b, les roues 40a et 42a et les renvois 40d et 42d sont respectivement montés pivotants sur la plaque 38 au moyen de tenons 48, 50, 52 et 54.As can be seen more particularly in FIGS. 3a and 3b, the wheels 40a and 42a and the references 40d and 42d are respectively pivotally mounted on the plate 38 by means of pins 48, 50, 52 and 54.

Les goupilles de la denture 36a sont disposées en cercle sur le disque annulaire que forme le mobile 36. Elles sont plus longues que les goupilles de la denture 36b, également disposées en cercle sur le mobile 36, le diamètre de ce deuxième cercle étant plus petit que celui du premier. La roue 40a se trouve à un premier niveau, supérieur, choisi de manière à ce que sa planche 40b soit en prise avec la denture 36a, mais n'entre pas en contact avec la denture 36b. La roue 42a se trouve à un deuxième niveau, inférieur, les découpes que comporte sa planche 42b étant en prise avec la denture 36b.The pins of the teeth 36a are arranged in a circle on the disc ring that forms the mobile 36. They are longer than the pins of the teeth 36b, also arranged in a circle on the mobile 36, the diameter of this second circle being smaller than that of the first. Wheel 40a is finds at a first level, higher, chosen so that his board 40b is engaged with the toothing 36a, but does not come into contact with the tooth 36b. Wheel 42a is at a second, lower level, the cutouts that includes its board 42b being engaged with the toothing 36b.

Comme expliqué plus haut, le mobile de commande 36 entraíne les disques 44a et 46b par l'intermédiaire des trains d'engrenages 40 et 42. Il est bien entendu que les disques doivent être entraínés selon une séquence telle que les dizaines changent à chaque passage du 9 au 0 des unités et que l'affichage passe de 31 à 1 à la fin de chaque mois.As explained above, the control mobile 36 drives the disks 44a and 46b through the gear trains 40 and 42. It is well understood that the records must be driven in a sequence such that the tens change with each passing from 9 to 0 units and that the display changes from 31 to 1 at the end of each month.

La figure 4 montre plus précisément comment est défini cette séquence. En 4a est représenté le disque des dizaines 46a et en 4b le disque des unités 44a. La partie 4c a une forme de tableau avec, en première ligne la date affichée à laquelle est associée une position du mobile de commande 36, en deuxième ligne les dizaines affichées, en troisième ligne la structure de la dentures 36b, en quatrième ligne les unités affichées et en cinquième ligne la structure de la denture 36a.Figure 4 shows more precisely how this sequence is defined. In 4a is represented the disk of the tens 46a and in 4b the disk of the units 44a. Part 4c has a table form with, in the first line, the date displayed with which is associated a position of the control wheel 36, in second line the displayed tens, in third line the structure of the teeth 36b, in fourth line the units displayed and in fifth line the structure of the toothing 36a.

Le disque des dizaines 46a, tel que représenté en 4a, comporte une portion centrale et quatre bras, chacun d'eux portant un chiffre, soit la séquence 0, 1, 2 et 3. Pour que l'affichage des dates soit correct, le disque 46a doit sauter lors du passage du 9 au 10, du 19 au 20, du 29 au 30 et du 31 au 1 er, sous l'action des dents de la denture 36b représentées sur la troisième ligne du tableau 4c. A cet effet, la denture 36b comporte quatre goupilles agencées de manière à assurer l'entraínement du disque 46a lors de chaque changement de dizaine.The tens disk 46a, as shown in 4a, comprises a portion central and four arms, each of them bearing a number, the sequence 0, 1, 2 and 3. For the date display to be correct, the disk 46a must jump when passing from 9 to 10, from 19 to 20, from 29 to 30 and from 31 to the action of the teeth of the teeth 36b represented on the third line of the table 4c. For this purpose, the toothing 36b comprises four pins arranged so as to ensure the drive 46a drive at each change dozen.

Le disque des unités 44a représenté en 4b doit sauter tous les jours sauf lors du passage du 31 au 1 er. C'est pourquoi, comme on peut le voir sur la 5ème ligne du tableau 4c, la denture comporte trente goupilles et un espace entre les goupilles assurant respectivement le passage du 30 au 31 et du 1er au 2. En d'autres termes, à cause de cet espace, le disque des unités 44a ne saute pas lors du passage du 31 au 1 er.The disk of the units 44a shown in 4b must jump every day except when from the 31st to the 1st. That's why, as we can see on the 5th row of Table 4c, the toothing has thirty pins and a space between the pins respectively providing the passage from 30 to 31 and from 1 to 2. In other words, because of this space, the disk of the units 44a does not jump not when going from 31 to 1 st.

La figure 5 représente, selon une même structure que celle de la figure 4, une variante d'affichage dans laquelle le disque des dizaines 46a comporte cinq indications, soit 0, 1, 2, 3 et 31. Selon cette variante, la denture 36b comporte cinq goupilles assurant respectivement le saut du disque 46a lors du passage du 9 au 10, du 19 au 20, du 29 au 30, du 30 au 31 et du 31 au 1 er. Quant au disque des unités 44a, il peut être entraíné lors du passage du 30 au 31. Il peut aussi l'être lors du passage du 31 au premier, comme représenté sur cette figure.FIG. 5 represents, according to the same structure as that of FIG. display variant in which the disk of the tens 46a has five indications, namely 0, 1, 2, 3 and 31. According to this variant, the toothing 36b comprises five pins respectively ensuring the jump of the disc 46a during the passage 9 to 10, 19 to 20, 29 to 30, 30 to 31 and 31 to 1. As to units 44a disc, it can be driven during the passage from 30 to 31. It can also be when going from 31 to the first, as shown on this figure.

On relèvera que les pignons 44b et 46b sont avantageusement positionnés au moyen de sautoirs coopérant avec leur denture. Ces derniers ne sont toutefois pas représentés, pour éviter de surcharger le dessin. It will be noted that the pinions 44b and 46b are advantageously positioned at means of jumper cooperating with their teeth. These are not however not shown, to avoid overloading the drawing.

Dans le mode de réalisation décrit, le mobile de commande 36 et les mobiles d'affichage 40 et 42 sont concentriques entre eux et aux arbres portant les aiguilles des heures, des minutes et des secondes. Il est également possible de réaliser un mécanisme dans lequel le mobile de commande est décentré par rapport au mouvement. Les mobiles d'affichage sont, ici aussi, disposés concentriquement au mobile de commande. Dans ce cas, l'affichage est plus petit, mais reste intéressant. Ces mobiles peuvent être concentriques à un arbre portant une aiguille d'affichage complémentaire, indiquant, par exemple, la seconde.In the embodiment described, the control mobile 36 and the mobiles 40 and 42 are concentric with each other and with the shafts bearing the needles hours, minutes and seconds. It is also possible to realize a mechanism in which the control wheel is off-center compared to the movement. Mobile displays are here too concentrically to the control mobile. In this case, the display is no longer small, but still interesting. These mobiles can be concentric to a shaft carrying a complementary display needle, indicating, for example, the second.

Dans une autre variante, il est possible de placer l'affichage à 3 heures, les chiffres étant alors orientés tangentiellement sur la périphérie des disques. Il est alors aussi possible de placer les deux disques 44a et 46a sur un même plan.In another variant, it is possible to place the display at 3 o'clock, the digits are then oriented tangentially on the periphery of the disks. he is then also possible to place the two disks 44a and 46a on the same plan.

Ainsi, grâce au fait que le mobile de commande et les mobiles d'affichage sont concentriques, il est possible de réaliser un affichage de la date de grande dimension, par des moyens simples.Thus, thanks to the fact that the mobile control and mobile display are concentric, it is possible to make a display of the date of large dimension, by simple means.
