Arrière-plan de l'inventionBackground of the invention

L'état de la technique comprend de nombreux documents relatifs aux dispositifs d'affichage AM/PM.The state of the art includes numerous documents relating to AM / PM display devices.

Il est connu d'afficher le moment de la journée au moyen d'un disque ayant une surface visible qui est entraîné de manière à effectuer un tour en vingt-quatre heures dans le même sens que l'aiguille des heures. La surface visible du disque définit visuellement deux demi-disques pour indiquer l'information AM-PM relative à l'heure affichée par cette aiguille des heures.It is known to display the time of day by means of a disc having a visible surface which is driven so as to perform one revolution in twenty-four hours in the same direction as the hour hand. The visible surface of the disc visually defines two half-discs to indicate the AM-PM information relating to the time displayed by this hour hand.

Cependant, un tel affichage ne permet pas une lecture simple et directe de l'information AM-PM, ce type d'affichage étant généralement de petite taille. De même, lors du réglage de l'heure il n'est pas aisé de vérifier rapidement s'il s'agit du de la matinée ou de l'après-midi.However, such a display does not allow simple and direct reading of the AM-PM information, this type of display being generally of small size. Likewise, when setting the time, it is not easy to quickly check whether it is the morning or the afternoon.

Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

Une pièce d'horlogerie comprenant au moins des moyens d'affichage analogique de l'heure, un dispositif d'affichage AM-PM pour afficher un information jour-nuit dans le cadran de ladite pièce d'horlogerie selon l'invention va maintenant être décrite dans ce qui suit faisant référence conjointement aux figures 1 à 5.A timepiece comprising at least analog time display means, an AM-PM display device for displaying day-night information in the dial of said timepiece according to the invention will now be used. described in the following referring in conjunction with figures 1 to 5 .

En référence aux figures 1 et 2, le cadran 2 d'une montre 1 est représenté par un disque et comporte au moins deux guichets 3, 3' dans lesquels apparaît respectivement une inscription indiquant AM ou PM, les deux guichets 3, 3' étant diamétralement opposés par rapport aux moyens d'affichage de l'heure 6 formés de manière classique par des aiguilles. Ces inscriptions sont inscrites sur un disque rotatif ou anneau appelé disque d'affichage 5, disposé sous le cadran 2, et qui porte une première série d'inscription AM et une deuxième série d'inscription PM. Dans le mode de réalisation représenté aux figures 1 et 2, ces deux séries de d'inscriptions sont disposées sur deux cercles concentriques, les inscriptions étant ici disposées côte à côte. La première série d'inscription se compose de sept inscription AM et sept inscriptions PM et occupe le cercle intérieur, les deux séries d'affichage étant disposées sur au moins deux cercles concentriques.With reference to figures 1 and 2 , the dial 2 of a watch 1 is represented by a disc and comprises at least two apertures 3, 3 'in which appears respectively an inscription indicating AM or PM, the two apertures 3, 3' being diametrically opposed with respect to the means of 6 hour display conventionally formed by hands. These inscriptions are inscribed on a rotating disc or ring called display disc 5, arranged under the dial 2, and which bears a first series of inscriptions AM and a second series of inscriptions PM. In the embodiment shown in figures 1 and 2 , these two series of inscriptions are arranged on two concentric circles, the inscriptions here being arranged side by side. The first series of inscriptions consists of seven inscriptions AM and seven inscriptions PM and occupy the inner circle, the two series of displays being arranged on at least two concentric circles.

La dispositif d'affichage comprend également un mécanisme d'entrainement agencé pour amener automatiquement et alternativement ladite première série d'inscription dans un premier guichet et ladite deuxième série d'inscription dans un deuxième guichet via une rotation dudit disque d'affichage.The display device also comprises a drive mechanism arranged to automatically and alternately bring said first series of inscriptions in a first window and said second series of inscriptions in a second window via a rotation of said display disc.

Comme on peut le remarquer, les inscriptions de chaque cercle sont disposées sur des rayons du disque d'affichage 5, les rayons étant espacés de 360°/7. Grâce à cette disposition, l'une des deux inscriptions est alternativement affichée dans l'un des deux guichets 3, 3', le passage de l'affichage AM à l'affichage PM correspondant à une rotation du disque d'affichage 5 d'un septième de tour, soit toutes les douze heures.As can be seen, the inscriptions of each circle are arranged on spokes of the display disc 5, the spokes being spaced 360 ° / 7. Thanks to this arrangement, one of the two inscriptions is alternately displayed in one of the two windows 3, 3 ', the change from the AM display to the PM display corresponding to a rotation of the display disc 5 of one seventh of a turn, or every twelve hours.

Cette disposition des inscription AM-PM est particulièrement avantageuse par rapport à une disposition classique où les inscriptions se suivent sur un même cercle, cela permet d'agrandir considérablement la taille des inscriptions tout en limitant l'encombrement sur le disque d'affichage et par conséquent facilite la lecture.This arrangement of the AM-PM inscriptions is particularly advantageous compared to a conventional arrangement where the inscriptions follow one another on the same circle, this makes it possible to considerably enlarge the size of the inscriptions while limiting the bulk on the display disc and by therefore makes it easier to read.

La montre dont le mouvement est partiellement représenté vu en coupe par la figure 5 comporte le cadran 2 avec un guichet 3 et le disque d'affichage 5.The watch, the movement of which is partially shown, seen in section through the figure 5 features dial 2 with aperture 3 and display disc 5.

Le mécanisme d'entraînement de ce disque d'affichage se compose d'une étoile 51 comportant une denture périphérique 52 se composant de quatorze dents et qui est agencée pour coopérer avec une roue 53 portant doigts 54 diamétralement opposés, la roue 53 étant entrainée par la roue des heures. L'étoile 51 est solidaire du disque d'affichage et centrée sur ce dernier, les deux pièces formant un élément d'un seul tenant.The drive mechanism of this display disc consists of a star 51 comprising a peripheral toothing 52 consisting of fourteen teeth and which is arranged to cooperate with a wheel 53 carrying diametrically opposed fingers 54, the wheel 53 being driven by the hour wheel. The star 51 is integral with the display disc and centered on the latter, the two parts forming an integral element.

Selon un autre mode de réalisation de l'invention visible aux figures 1 et 2a, le disque d'affichage 5 comprend des inscriptions supplémentaires de manière à afficher égalent le jour de la semaine dans l'un des guichets 3, 3'.According to another embodiment of the invention visible to figures 1 and 2a , the display disc 5 comprises additional inscriptions so as to display equal to the day of the week in one of the windows 3, 3 '.

Grâce à ces différents aspects de l'invention, on dispose d'un dispositif d'affichage AM/PM permettant une lecture simple et de faciliter le réglage de la montre après une période prolongée au cours de laquelle la montre n'a pas été portée. L'invention permet également de faciliter les opérations de montage/ démontage ainsi que l'entretien d'une pièce d'horlogerie équipée d'un dispositif conforme à l'invention.Thanks to these different aspects of the invention, there is an AM / PM display device allowing easy reading and facilitating the adjustment of the watch after a prolonged period during which the watch has not been worn. . The invention also makes it possible to facilitate the assembly / disassembly operations as well as the maintenance of a timepiece equipped with a device in accordance with the invention.
