Abstract

The retrograde indication or display incorporates a mobile indicatory component (1) displaceable angularly in forward and backward movements between a position between zero and maximal values of the extent indicated and a position corresponding to half the maximal value of the extent indicated. A clockwork application is involved. The mobile indicatory component moves in relation to two graduations (2,3), the first extending from zero to half of the maximum value of the extent indicated and the second in the opposite direction.

Description

       

  



   Il existe de nombreux affichages rétrogrades dont l'un des plus simples  du point de vue du mécanisme est celui décrit dans le brevet CH 666  591. 



   Tous les affichages rétrogrades connus présentent un point commun,  l'organe d'affichage mobile se déplace dans un sens à la vitesse  d'incrémentation du temps jusqu'à une valeur maximale de la grandeur  affichée, puis cet organe d'affichage mobile revient à zéro de façon  instantanée. 



   La présente invention a pour objet un affichage rétrograde différent  en ce que l'organe mobile d'affichage effectue un mouvement de va  et vient en regard d'une graduation mais toujours à la même vitesse.  Ceci permet une esthétique particulière et nouvelle d'une pièce d'horlogerie.                                                  



   L'affichage rétrograde selon l'invention se distingue par les caractéristiques  énoncées à la revendication 1. 



   Le dessin annexé illustre schématiquement et à -titre d'exemple une  forme d'exécution de l'affichage rétrograde selon l'invention et  de son mécanisme.      La fig. 1 illustre le cadran d'une pièce  d'horlogerie comportant un affichage rétrograde des secondes selon  l'invention.     Les fig. 2 à 5 illustre le mécanisme de l'affichage  rétrograde dans quatre positions différentes.  



   L'affichage rétrograde selon l'invention comporte un organe d'affichage  mobile, ici une aiguille 1 entraînée par un mécanisme en regard de  deux graduations 2, 3 de sens opposé. Chaque graduation correspond  à la moitié des valeurs que peut prendre la grandeur affichée. Le  mécanisme, qui sera décrit plus loin, entraîne l'aiguille 1 de zéro  à trente secondes de gauche à droite et la lecture s'effectue sur  la première graduation 2. Ensuite l'aiguille 1 est entraînée de trente  à soixante secondes en sens inverse, soit de droite à gauche et la  lecture se fait sur la seconde graduation 3. Dans ce type d'affichage  rétrograde alternatif    l'aiguille 1 progresse jusqu'à son point  extrême, correspondant à la moitié de la valeur maximale de la grandeur  affichée, puis revient progressivement à son point de départ. 



   Le mécanisme entraînant l'aiguille 1 dans ses déplacements de va  et vient comporte un pignon 4 pivoté sur une platine dont l'axe porte  l'aiguille 1. Ce pignon 4 est soumis à l'action de rappel élastique  d'un ressort spirale 5 tendant à le maintenir dans une position par  laquelle l'aiguille indique zéro. Ce pignon 4 engrène avec le secteur  denté 6 d'un levier 7 pivoté en 8 sur la platine et dont l'autre  extrémité est munie d'un bec 9 maintenu en contact avec une came  10 sous l'action du ressort spirale 5. 



   La came 10 est entraînée en rotation à raison d'un tour en une minute  par un affichage des secondes, d'un tour en un jour pour l'affichage  de 24 heures, d'un tour en sept jour pour un affichage de jour ou  d'un tour par mois pour un affichage du quantième. 



   Cette came 10 présente la forme d'un coeur dont la partie la plus  élevée correspond à la moitié de la valeur maximale que peut prendre  l'affichage tandis que son point le plus bas correspond à l'affichage  de la valeur zéro ou maximale de la grandeur à afficher. 



   Ce mécanisme peut être intégré dans un mouvement d'horlogerie ou  constituer un module additionnel. 



   Un tel module permet l'affichage de différente information au moyen  d'une aiguille rétrograde affichant la moitié de l'information en  avançant dans une direction puis l'autre moitié pendant la course  de retour en sens inverse de l'aiguille. 



   Ce mécanisme permet de diviser un cycle en deux parties rigoureusement  égales. 



   Suivant la vitesse de rotation de la came 10 on peut réaliser un  affichage des secondes, des heures, des minutes, des jours ou du  quantième par exemple.



  



   There are many retrograde displays, one of the simplest from the point of view of the mechanism is that described in patent CH 666 591.



   All known retrograde displays have one thing in common, the mobile display member moves in one direction at the rate of incrementation of time up to a maximum value of the displayed quantity, then this mobile display member returns to zero instantly.



   The present invention relates to a different retrograde display in that the movable display member performs a back and forth movement opposite a graduation but always at the same speed. This allows a particular and new aesthetic of a timepiece.



   The retrograde display according to the invention is distinguished by the characteristics set out in claim 1.



   The attached drawing illustrates schematically and by way of example an embodiment of the retrograde display according to the invention and its mechanism. Fig. 1 illustrates the dial of a timepiece comprising a retrograde seconds display according to the invention. Figs. 2 to 5 illustrates the mechanism of the retrograde display in four different positions.



   The retrograde display according to the invention comprises a movable display member, here a needle 1 driven by a mechanism opposite two graduations 2, 3 in opposite directions. Each graduation corresponds to half the values that the displayed quantity can take. The mechanism, which will be described later, drives the hand 1 from zero to thirty seconds from left to right and the reading is carried out on the first scale 2. Then the hand 1 is driven from thirty to sixty seconds in the opposite direction , ie from right to left and the reading is done on the second graduation 3. In this type of alternative retrograde display, needle 1 progresses to its extreme point, corresponding to half of the maximum value of the quantity displayed, then gradually returns to its starting point.



   The mechanism driving the needle 1 in its back and forth movements comprises a pinion 4 pivoted on a plate whose axis carries the needle 1. This pinion 4 is subjected to the elastic return action of a spiral spring 5 tending to maintain it in a position by which the needle indicates zero. This pinion 4 meshes with the toothed sector 6 of a lever 7 pivoted at 8 on the plate and the other end of which is provided with a spout 9 held in contact with a cam 10 under the action of the spiral spring 5.



   The cam 10 is rotated at the rate of one revolution in one minute by displaying the seconds, one revolution in one day for the display of 24 hours, one revolution in seven days for the display of the day or one turn per month for a date display.



   This cam 10 has the shape of a heart, the highest part of which corresponds to half the maximum value that the display can take, while its lowest point corresponds to the display of the zero or maximum value of the quantity to display.



   This mechanism can be integrated into a timepiece movement or constitute an additional module.



   Such a module allows the display of different information by means of a retrograde hand displaying half of the information advancing in one direction and then the other half during the return stroke in the opposite direction of the needle.



   This mechanism makes it possible to divide a cycle into two strictly equal parts.



   Depending on the speed of rotation of the cam 10, it is possible to display seconds, hours, minutes, days or the date for example.
