Abstract

The device has two indicator disks (1,2) arranged side by side, where the disk (1) indicates units of the date and the disk (2) indicates tens of the date. The units and tens appear side by side in an aperture (3) arranged across an hour indicator dial. The disks are transparent such that color of an underlying surface (4) of the disks is contrast to the color of the date indication.

Description

La présente invention a pour objet un dispositif d'affichage des quantièmes pour pièce d'horlogerie, comprenant deux disques indicateurs disposés côte à côte, l'un portant les chiffres des unités, l'autre ceux des dizaines, les deux chiffres côte à côte des deux disques respectifs apparaissant dans un guichet ménagé au travers d'un cadran indicateur de l'heure.The present invention relates to a display device timepieces for a timepiece, comprising two indicator discs arranged side by side, one carrying the numbers of the units, the other ones of the tens, the two numbers side by side of the two respective disks appearing in a window arranged through an indicator dial Of time.

Pour permettre d'augmenter la taille des chiffres des quantièmes d'une montre bracelet en particulier, il a déjà été proposé d'utiliser deux disques, l'un portant les chiffres des unités et l'autre celui des dizaines. Lorsque l'on dispose ces disques côte à côte, de manière à faire apparaítre au travers d'un guichet les deux portions adjacentes de ces disques situées de part et d'autre d'une ligne reliant leurs centres respectifs, les portions des bords des disques situées à l'intérieur du guichet apparaissent. Pour dissimuler ces bords de disques, on divise généralement le guichet en deux par une étroite traverse verticale médiane, ménageant un demi-guichet gauche pour l'affichage du chiffre des dizaines et un demi-guichet droit pour l'affichage des unités.To increase the size of the numbers of dates of a particular wristwatch, it has already been proposed to use two discs, one bearing the figures units and the other tens. When one arrange these discs side by side, so as to show through a window the two adjacent portions of these disks located on both sides of a connecting line their respective centers, the portions of the edges of the disks located inside the window appear. To conceal these disk edges, we usually divide the wicket in two by a narrow median vertical crossbar, sparing a half-counter left for the display of the number of tens and a half-wicket right for displaying units.

On a aussi proposé des solutions dans lesquelles les deux disques sont superposés, un des chiffres apparaissant au travers d'une ouverture ménagée dans le disque supérieur. Cette solution présente cependant l'inconvénient d'avoir les deux chiffres du quantième situés à deux niveaux différents. On a également proposé dans le EP 1 070 996 de faire le disque supérieur en un matériau transparent, ce qui évite de devoir ménager une ouverture, mais ne résout pas le problème de l'affichage des deux chiffres à des niveaux différents. Solutions have also been proposed in which two disks are stacked, one of the numbers appearing through an opening in the upper disk. This solution, however, has the disadvantage of having the two date digits located at two different levels. It has also been proposed in EP 1 070 996 to make the disc superior in a transparent material, which avoids must have an opening, but do not solve the problem displaying two digits at different levels.

Une autre variante de la solution précédente est décrite dans le WO 03/071361 et présente donc le même inconvénient, à savoir celui d'afficher les deux chiffres des quantièmes sur deux niveaux différents.Another variant of the previous solution is described in WO 03/071361 and therefore has the same disadvantage, to know to display the two digits of the dates on two different levels.

Le but de la présente invention est d'apporter une solution capable de remédier, au moins partiellement, aux inconvénients susmentionnés.The object of the present invention is to provide a solution able to remedy, at least partially, the disadvantages above.

A cet effet, cette invention a pour objet un dispositif d'affichage des quantièmes pour pièce d'horlogerie selon la revendication 1.For this purpose, this invention relates to a device display of timepieces for a timepiece according to the claim 1.

La figure unique du dessin annexé illustre, schématiquement et à titre d'exemple, une vue de dessus d'une forme d'exécution du dispositif d'affichage objet de la présente invention.The single figure of the appended drawing illustrates, schematically and as an example, a top view of a shape execution of the display device object of this invention.

Pour la compréhension de la présente invention, l'homme de métier n'a pas besoin de connaítre le mécanisme d'entraínement du dispositif d'affichage, celui-ci étant un dispositif de quantièmes du type appelé "grande date" tout à fait classique, bien connu de l'homme de métier. Grâce à ce mécanisme, le disque des unités est entraíné d'un pas chaque jour et celui des dizaines d'un pas tous les dix jours. En fin de mois, si il s'agit d'un mécanisme de quantièmes annuel ou perpétuel, le passage du 28, 29, 30 ou 31 au 1 du mois suivant s'effectuera automatiquement par un mécanisme connu qui neutralise le disque des unités si le mois a 31 jours et n'entraíne que celui des dizaines ou qui entraíne les deux disques d'un pas si le mois a 30 jours. Si il s'agit d'un mécanisme perpétuel, il effectuera la correction également pour le mois de février. Enfin si il s'agit d'un quantième simple, la correction s'effectue à la main, chaque fois que le mois a moins de 31 jours.For the understanding of the present invention, the man profession does not need to know the drive mechanism of the display device, the latter being a device of the type called "big date" quite classic, well known to the skilled person. Thanks to this mechanism, the disc of the units is driven with a step each day and that dozens of a step every ten days. In end of the month, if it is an annual calendar mechanism or perpetual, the passage of 28, 29, 30 or 31 to 1 of next month will be done automatically by a mechanism known that neutralizes the units disk if the month has 31 days and only train the tens or that leads the two disks one step if the month has 30 days. If it is of a perpetual mechanism, he will perform the correction also for the month of February. Finally if it is a simple calendar, the correction is done by hand, each once the month is less than 31 days old.

Le dispositif d'affichage selon l'invention comporte donc deux disques côte à côte, un disque des unités 1 portant les chiffres de 0 à 9 et un disque des dizaines 2 portant au moins une série de quatre chiffres 0 à 3, le 0 pouvant être remplacé par un espace vide ou par un élément décoratif. De préférence, le disque des dizaines comporte deux séries de chiffres de 0 à 3, ce qui lui permet de se rapprocher du nombre de chiffres du disque des unités et de faire ainsi deux disques ayant sensiblement le même diamètre.The display device according to the invention comprises therefore two discs side by side, a disc of the units 1 carrying the numbers from 0 to 9 and a record of tens 2 carrying at least a series of four digits 0 to 3, the 0 being be replaced by an empty space or by an element decorative. Preferably, the disk of the tens comprises two sets of numbers from 0 to 3, which allows him to compare the number of digits of the units disk and thus make two disks having substantially the same diameter.

Ces deux disques 1, 2 sont transparents, les chiffres qu'ils portent étant d'une couleur, par exemple noire, comme habituellement. Seule les parties de ces disques 1, 2 situées à l'intérieur du guichet qui est représenté par un rectangle 3 sur le dessin sont visible pour l'observateur, en sorte que le mécanisme d'entraínement de ces disques 1, 2 peut se situer facilement hors du champ de vision du guichet 3. Sous ces parties des disques 1, 2 et de préférence un peu au-delà pour tenir compte de la parallaxe, la surface qui apparaít à travers ces parties des disques 1, 2 transparents est d'une couleur contrastant avec celle des chiffres portés par ces disques, par exemple, si les chiffres sont noirs, la surface qui apparaít à travers les disques 1, 2 sera blanche ou tout au moins claire. Etant donné que les disques sont transparents, leurs bords respectifs sont presque invisibles, en sorte qu'il n'est plus nécessaire de séparer le guichet 3 en deux par une traverse médiane pour cacher les bords des disques 1, 2.These two disks 1, 2 are transparent, the figures that they wear being of a color, for example black, as habitually. Only the parts of these disks 1, 2 located inside the wicket which is represented by a rectangle 3 on the drawing are visible to the observer, so that the drive mechanism of these disks 1, 2 can be easily located outside the box office 3. Under these parts of discs 1, 2 and preferably a little beyond to account for the parallax, the surface that appear through these parts transparent disks 1, 2 is of a color contrasting with that of the figures worn by these disks, for example, if the numbers are black, the surface that appears through the disks 1, 2 will be white or at least clear. Since the discs are transparent, their respective edges are almost invisible, so that it is no longer necessary to separate the wicket 3 in two by a median cross to hide the edges of the discs 1, 2.

La surface sous-jacente aux disques 1, 2 apparaissant en transparence dans le guichet 3 peut être ménagée sur une plaquette 4 fixée au bâti, en général à la platine de la pièce d'horlogerie par des vis 4a. Au cas où la portion du bâti située sous le guichet 3 présente une surface unie, la plaquette 4 peut être supprimée et la surface contrastante destinée à apparaítre sous les portions des disques 1, 2 situées dans le guichet 3 peut être directement ménagée sur la platine par revêtement total ou partiel de celle-ci de la couleur contrastante désirée. Si les essais effectués ont montré que le fond blanc et les chiffres noirs donnent de bons résultats, on peut également envisager de faire l'inverse, des chiffres blancs sur fond noir. Toutefois cette solution semble moins favorable à première vue. Etant donné que les disques transparents produisent un reflet, il peut être avantageux de choisir une couleur contrastante brillante pour atténuer la différence entre les portions de la surface de fond 4 qui sont recouvertes par les disques 1, 2 et les zones 4a de cette même surface de fond situées entre les disques 1, 2 et qui ne sont pas recouvertes par eux.The surface underlying the disks 1, 2 appearing transparency in the box 3 can be arranged on a plate 4 fixed to the frame, generally to the plate of the timepiece by screws 4a. In case the portion of frame under the window 3 has a solid surface, the pad 4 can be removed and the contrasting surface intended to appear under the portions of the discs 1, 2 located in the box 3 can be directly arranged on platinum by total or partial coating thereof contrasting color desired. If the tests carried out showed that the white background and the black numbers give good results, we can also consider doing the opposite, white numbers on a black background. However this solution seems less favorable at first sight. Given that transparent discs produce a reflection, it can be advantageous to choose a brilliant contrasting color to mitigate the difference between the portions of the surface background 4 which are covered by discs 1, 2 and zones 4a of this same bottom surface located between discs 1, 2 and which are not covered by them.

Les disques transparents 1, 2 peuvent être en matière plastique ou en verre. Dans le cas où ils sont en matière plastique, ils pourraient être obtenus par injection en positionnant des chiffres réalisés par exemple par découpage, dans le moule d'injection, de manière à ce qu'ils soient au moins partiellement noyés dans la matière plastique injectée. Ces chiffres pourraient avoir une certaine épaisseur, par exemple correspondant à l'épaisseur du disque transparent 1, 2, ce qui leur donnerait un relief particulier, encore inconnu jusqu'ici puisqu'on verrait alors la tranche de ces chiffres, étant donné qu'ils sont noyés dans un disque transparent.The transparent discs 1, 2 can be made of plastic or glass. In the case where they are in plastic they could be obtained by injection by positioning figures made for example by cutting, in the injection mold, so that they are at less partially embedded in the injected plastic material. These figures could have a certain thickness, for example corresponding to the thickness of the transparent disk 1, 2, which would give them a particular relief, still unknown so far since we would see the slice of these numbers, since they are drowned in a transparent disc.
