Abstract

The display mechanism provides a large-size date display for a watch through a window, utilizing a first digital support disk (A) including units and graduated at least from 0 to 9 and second digital support (B) in the form of an arc segment for displaying the tens, i.e. 1-3. The disk describes at least an arc driving the digits beneath the window based on the selected time unit. The second arc segment describes an arc whose center is placed outside a circle formed by the support disk, so that the figures of the tens are spaced apart by a non-obstructing zone revealing the first disk. The second arc segment is urged to be superimposed on the first disk to form the two digits of a date number.

Description

La présente invention a pour but la réalisation d'un mécanisme d'affichage pour tout types de mouvement de montre, en particulier pour montre bracelet, plus grand que ceux connus, permettant ainsi une lecture plus aisée d'un indicateur de quantième comportant des unités et des dizaines.The present invention aims to achieve a display mechanism for all types of watch movements, in particular for wristwatches, larger than those known, thus allowing easier reading of a date indicator comprising units and tens.

La plupart des mécanismes connus à ce jour, qui permettent l'affichage d'un grand quantième sont conçus de la même manière à savoir : deux disques, le premier étant un disque des unités du quantième, entraíné par un train d'engrenage démultiplicateur depuis la base de temps du mouvement, en général partant depuis son centre. Le deuxième disque est celui des dizaines du quantième, dont le centre est inscrit dans le disque des unités, lequel par une denture permet d'entraíner ledit disque des dizaines.Most of the mechanisms known to date, which allow the display of a grand date are designed in the same way, namely: two discs, the first being a disc of the date units, driven by a train reduction gear from the time base of the movement, in general leaving from his center. The second disc is that of the tens of the date, the center of which is inscribed in the disc of the units, which by a toothing allows to drive said tens disc.

Un tel système est décrit dans le document EP 0 529 191, illustrant la solution à deux disques, le disque des dizaines étant en forme d'étoile à quatre branches. L'axe de rotation du disque des dizaines s'inscrit à l'intérieur du disque des unités, ce dernier formant la circonférence de la montre.Such a system is described in document EP 0 529 191, illustrating the solution with two discs, the tens disc being in the shape of a four-star branches. The axis of rotation of the tens disc fits inside the disc of the units, the latter forming the circumference of the watch.

Ce type de réalisation est principalement adapté pour des mouvements circulaires.This type of realization is mainly adapted for movements circular.

Le but de la présente invention est de proposer une solution permettant l'affichage d'un quantième de grande taille offrant de larges possibilités d'implantation dans un mouvement de montre.The aim of the present invention is to propose a solution allowing the display of a large calendar offering wide possibilities of implantation in a watch movement.

Ce but est atteint par un mécanisme d'affichage d'un quantième de grande taille pour instrument horaire au travers d'un guichet, mettant en oeuvre un premier support numérique comprenant les unités et gradué d'au moins 0 à 9 et un second support numérique comprenant les dizaines, le premier support décrivant au moins un arc de cercle balayant les décimales sous le guichet selon l'unité de temps choisie, caractérisé en ce que le second support numérique décrit un arc de cercle dont le centre est placé en dehors du cercle formé par le premier support et dont les chiffres des dizaines sont espacés par une zone non obstruante laissant apparaítre le premier support, ce second support venant se superposer sur le premier support pour former les deux décimales d'un nombre.This goal is achieved by a date display mechanism of large size for time instrument through a window, implementing a first digital support comprising the units and graduated from at least 0 to 9 and a second digital medium comprising the tens, the first medium describing at least an arc sweeping the decimals under the window according to the chosen time unit, characterized in that the second support numeric describes an arc of a circle whose center is placed outside the circle formed by the first support and whose tens digits are spaced by a non-obstructing area revealing the first support, this second support coming to be superimposed on the first support to form the two decimals of a number.

Par support numérique on entend un support qui peut être de différentes formes, par exemple un disque, un secteur ou une portion de disque, sur lequel est placé la graduation souhaitée. Cette graduation peut être pour le premier support des unités de 0 à 9, ou un multiple soit de 0 à 9 deux fois si la place le permet.By digital medium is meant a medium which can be of different shapes, for example a disc, sector or portion of a disc, on which is placed the desired graduation. This graduation can be for the first support of units from 0 to 9, or a multiple of 0 to 9 twice if the place allows.

Pour ce qui concerne le second support des dizaines, selon l'application il portera les chiffres 0 à 3 si l'on souhaite afficher le quantième du mois, soit une autre graduation si l'on souhaite afficher le quantième de la semaine par exemple.Regarding the second tens support, depending on the application, will carry the numbers 0 to 3 if you want to display the calendar of the month, another graduation if you want to display the calendar of the week by example.

L'invention sera mieux comprise grâce à la description détaillée qui va suivre et qui se réfère aux dessins annexés qui sont donnés à titre d'exemple nullement limitatif, dans lesquels:

  • la figure 1 représente une vue par dessus d'un dispositif selon l'invention mettant en oeuvre un premier support en forme de disque et un second support en forme de secteur,
  • la figure 2 correspond à la vue éclatée de la figure 1,
  • la figure 3 représente une vue par dessus d'un dispositif selon l'invention mettant en oeuvre un premier support et un second support en forme de secteur.
The invention will be better understood thanks to the detailed description which follows and which refers to the appended drawings which are given by way of non-limiting example, in which:
  • FIG. 1 represents a view from above of a device according to the invention using a first support in the form of a disc and a second support in the form of a sector,
  • FIG. 2 corresponds to the exploded view of FIG. 1,
  • Figure 3 shows a top view of a device according to the invention using a first support and a second sector-shaped support.

Sur les figures 1 et 2, la roue (1) est la prise de force depuis le mouvement de base, qui porte un doigt (2) et fait un tour en 24 heures. La roue (1) engrène avec la roue (3) qui porte un doigt élastique (4). Le rapport d'engrenage entre la roue (1) et la roue (3) est de un de sorte que la roue (3) fait également un tour en 24 heures.In Figures 1 and 2, the wheel (1) is the PTO from the movement of base, which wears a finger (2) and goes around in 24 hours. The wheel (1) meshes with the wheel (3) which carries an elastic finger (4). The gear ratio between the wheel (1) and the wheel (3) is one so that the wheel (3) also makes a round in 24 hours.

Le bec (4a) du doigt (4) entraíne ainsi une fois par jour le disque des unités (A) lequel est muni d'une étoile (5), solidaire, à 10 positions, de 0 à 9. Ce disque est verrouillé par un sautoir (6). La roue (1) entraíne également une roue (20) faisant également un tour en 24 heures portant un doigt solidaire (21) qui entraíne à chaque tour une étoile (22) dont le nombre de dents est choisi en fonction du nombre de dizaines à indiquer, en l'occurrence 31. Cette étoile est verrouillée par un sautoir (27). Cette étoile porte une came (23) solidaire comportant plusieurs rayons (23a-23b-23c-23d) en fonctions du nombre de dizaines à indiquer, en l'occurrence 4. Le rayon (23d) à un angle de révolution plus court que les autres, du fait qu'il n'y a que 30 et 31 jours. Cette came est en liaison avec un secteur (24) et est mû par son bec (24a). Le dit secteur est maintenu en contact avec la came (23) par un ressort (25). Le secteur (24) entraíne par sa denture (24b) le secteur des dizaines (B) par son pignon solidaire (26). Le secteur des dizaines étant superposé au disque des unités, il comporte des espaces permettant la lecture des chiffres des unités, ainsi que le démontrent les figures 1 et 2.The beak (4a) of the finger (4) thus drives the disc of the units (A) once a day which is provided with a star (5), integral, with 10 positions, from 0 to 9. This disc is locked by a jumper (6). The wheel (1) also drives a wheel (20) also doing a tour in 24 hours wearing a solid finger (21) which each star causes a star (22) whose number of teeth is chosen by function of the number of tens to indicate, in this case 31. This star is locked by a jumper (27). This star carries a cam (23) integral comprising several rays (23a-23b-23c-23d) depending on the number of tens to indicate, in this case 4. The radius (23d) at an angle of revolution shorter than the others, because there are only 30 and 31 days. This cam is in connection with a sector (24) and is moved by its beak (24a). The said sector is maintained in contact with the cam (23) by a spring (25). The sector (24) drives by its teeth (24b) the tens sector (B) by its pinion integral (26). The tens sector being superimposed on the units disc, it has spaces for reading unit numbers, as well as shown in Figures 1 and 2.

Lors du 31ème jour, la came des dizaines va entraíner les secteurs (24 et B) dans une position qui laisse apparaítre au travers d'une ou deux ouvertures du cadran, une indication du chiffre 0 ou une plage vide. De manière à ce que le mécanisme affiche le 1er jour, il faut empêcher le 1 des unités du 31ème jour de tourner. Pour cela, le mécanisme comporte une étoile (30) entraínée d'une dent par jour par le doigt (2) de la roue (1). La dite étoile (30) comporte 31 dents, verrouillée par un sautoir 31, elle porte un doigt (32) solidaire. Le bec (32a) dudit doigt, le 31ème jour appuie sur le flanc (33a) du levier de débrayage (33) lequel pivote en son axe (34). Ainsi son flanc (33b) vient appuyer sur le bras du ressort élastique (4) de sorte que le bec (4a) ne peut entraíner une des dents de l'étoile 5 du disque des unités (A) qui ne change donc pas de position d'où le maintien du chiffre 1 des unités.At the 31st day, the tens cam will cause the sectors (24 and B) at a position which reveals through one or two openings of the dial, an indication of the number 0 or an empty beach. So that the mechanism displays the 1st day, we must prevent the 1 units of the 31th day running. For this, the mechanism comprises a star (30) driven a tooth a day by the finger (2) of the wheel (1). Said star (30) has 31 teeth, locked by a jumper 31, it carries a finger (32) secured. The mouthpiece (32a) of said finger, the 31st day based on the flank (33a) of the release lever (33) which pivots on its axis (34). Thus its side (33b) comes to press on the arm of the elastic spring (4) so that the beak (4a) cannot drive one of the teeth of the star 5 of the disc of the units (A) which therefore does not change position hence the maintenance of the number 1 of the units.

Sur la figure 3, le disque des unités est remplacé par un secteur des unités (A') à 10 positions de 0 à 9, également inscrit sur un même rayon extérieur que le secteur des dizaines, mû par un engrenage monté en lieu et place du disques des unités (A) des figures 1 et 2 engrenant par l'intermédiaire d'un pignon oscillant (40) lequel par une forme aménagée dans un bras du secteur des unités avec la denture dudit secteur des unités (A'). Le pivotement du secteur des unités est situé à n'importe quel emplacement dans ou à l'extérieur du mécanisme. Le retour à zéro s'opère au moyen du désengrenage du pignon oscillant en fin de course du secteur, lequel est ramené sous l'action du ressort (50).In Figure 3, the drive disk is replaced by a drive sector (A ') with 10 positions from 0 to 9, also written on the same external radius that the tens sector, moved by a gear mounted in place of the discs of the units (A) of FIGS. 1 and 2 meshing by means of a oscillating pinion (40) which by a shape arranged in an arm of the sector units with the toothing of said sector of units (A '). The pivoting of the unit area is located at any location in or at outside the mechanism. The return to zero is effected by means of the declutching of the oscillating pinion at the end of travel of the sector, which is brought back under the action of the spring (50).

Bien que le premier champ d'application de ce type d'affichage est le quantième du mois, cette invention recouvre également l'affichage de textes voire la combinaison de textes et de chiffres. Le premier disque pourrait ainsi supporter les jours de la semaine, et le secteur pourrait lui supporter les mois.Although the first scope of this type of display is calendar of the month, this invention also covers the display of texts or even the combination of texts and numbers. The first disc could thus withstand the days of the week, and the industry could withstand the months.
