Abstract

The clockwork mechanism permits numerical indication by means of two disks and instantaneous change of indication, together with an easy rapid manual correction. An elastic arm (A) causes the mobile (31) teeth counter (C) to turn instantaneously. The particular arrangement of the teeth on the mobile causes the stars (U,D), supporters of the indication disks, to advance simultaneously or separately. The mechanism showing the date (31) explins the automatic change to be operated at midnight. The elastic arm (A) activates the spring (E) and when the counter (C) advances by one step, the tooth (1) causes the star (D) to advance by one step, whilst the tooth (O) passes underneath star (U) without touching it. The result is that the tens disk shows the zero (0) and the 1 indicated by the units disk remains immobile.

Description

       

  



   La présente invention a pour objet un mécanisme d'horlogerie permettant  un affichage numérique, notamment de l'indication de l'heure ou d'un  quantième, avec lisibilité accrue par le moyen de deux disques, l'un  indiquant par exemple les unités et l'autre les dizaines, permettant  notamment le changement d'affichage d'une façon instantanée ainsi  que sa correction rapide. 



   Ces affichages ont souvent été réalisés dans des pièces d'horlogerie  et à divers degrés de perfection. 



   La présente invention, destinée principalement à des montres bracelets,  a pour but d'améliorer ces affichages par le moyen d'un mécanisme  inédit qui permet, par sa simplicité, une fiabilité totale, un changement  instantané et une possibilité de correction rapide à tous moments,  y compris pendant le changement automatique. 



   Ce mécanisme a été réalisé pour un affichage de la date et sa construction  a été faite sur un mouvement existant afin d'en tester sa fiabilité.  Les résultats obtenus nous ont prouvé la validité de la présente  invention.      La fig. 1 représente, à titre d'exemple, une  vue de la grandeur de l'affichage, objet de la présente invention,  obtenue par le moyen de deux disques parallèles sous un cadran d'un  diamètre de 27 mm, dimension habituellement employée actuellement.     La fig. 2 représente un affichage obtenu sur un même cadran  mais au travers de deux disques coaxiaux.     La fig. 3 montre  les composants du mécanisme.

   Nous pouvons ainsi voir une roue de  24 heures, porteuse d'un doigt élastique A et d'une butée B, qui  entraîne une étoile de 31 dents C positionnée par son sautoir E,  les étoiles porteuses des disques d'affichages D et U avec leurs  sautoirs DD et UU, ainsi que le correcteur F et sa butée G servant  à la correction rapide.  



   La roue de 24 heures, entraînée d'une façon traditionnelle par le  mouvement, tourne en sens horaire et par le moyen de son bras élastique  A entre en contact avec l'étoile C. Ce bras va s'armer jusqu'au moment  où il touchera la butée B, dès ce moment, c'est le ressort E qui  fléchit et l'étoile C commence à tourner. La rupture d'équilibre  et donc l'avancement d'une dent de l'étoile C arrive avant le contact  des dents de l'étoile C avec ceux des étoiles U et D. 



   La rencontre des dents de l'étoile C avec ceux des étoiles U et D,  porteuses des disques d'affichage, permet, d'une façon sure et instantanée,  grâce à l'énergie emmagasinée par le bras élastique A et le sautoir  E, bien plus importante que la résistance des sautoirs UU et DD,  l'avancement d'un pas de l'affichage. 



     Le positionnement angulaire qui est assigné par les sautoirs respectifs  entre C et U-D, évite leurs contacts avant la fonction, empêche un  double saut et contribue à la sécurité du mécanisme. 



   L'étoile C, pièce maîtresse du mécanisme, possède 31 dents comme  une normale roue de quantième mais son épaisseur n'est pas uniforme  et cette caractéristique lui permet d'entraîner les étoiles U et  D d'une façon particulière. 



   Pour comprendre le fonctionnement de l'étoile C et de ses trois étages,  la fig. 4 montre schématiquement une coupe des étoiles du mécanisme.                                                           



   Le mobile C peut être revenu d'une étoile dont on soustrait par fraisage  les épaisseurs pour obtenir les divers étages, ou bien être composé  de parties usinées séparément, indexées et assemblées ensuite. 



   L'étage Zéro possède 31 dents qui sont positionnées par le sautoir  E et coopèrent avec le doigt élastique A et le correcteur F. 



   L'étage Unités possède 30 dents qui coopèrent avec l'étoiles des  unités U, tandis que l'étage Dizaines possède 5 dents qui coopèrent  avec les étoiles D et U. 



   La fig. 3 montre le mécanisme affichant la date 31 et explique le  changement automatique qu'il va opérer à minuit. Le doigt élastique  A va armer le ressort E et lorsque C avancera d'un pas, la dent 1  fera avancer l'étoile D d'un pas tandis que la dent 0 passera sous  l'étoile U sans la toucher. Résultat, le disque des dizaines affichera  le 0, et le 1, affiché par le disque des unités, restera immobile.                                                             



   Le lendemain, lorsque C avancera d'un pas, l'une des 30 dents de  son étage unités, dans ce cas la dent 17, entrera en contact avec  l'étoile U et la fera avancer d'un pas, tandis que la dent 2 passera  sous l'étoile D sans la toucher. 



   La charge additionnelle de ce mécanisme sur la marche de la montre  est tout à fait acceptable, l'armage du bras élastique A se répartit  sur une durée d'environ 4 heures. 



   La rapidité de la correction manuelle de ce mécanisme permet d'accepter  le fait qu'elle est unidirectionnelle et de ce fait, dans la sécurité  la plus absolue. 



   Le correcteur F, tournant uniquement en sens horaire, fait avancer  l'étoile C et donc l'affichage, si A est en prise avec l'étoile C,  la force manuelle de la correction fera fléchir A sans dommages résiduels.                                                     



   Lors de la remise à l'heure manuelle, si A tourne en sens horaire  et F est en prise, F s'éloignera de G sans dommages résiduels; si  A tourne en sens contraire il fléchira et ne provoquera pas de changements  à l'affichage. 



   Le principe de ce mécanisme étant caractérisé par le mobile compteur  à engrènement sélectif, il va de soi qu'avec d'autres nombres de  dents, soit sur le mobile compteur, soit sur les mobiles d'affichages,  on peut réaliser d'autres affichages que la date, exemples des heures  sautantes, des fuseaux horaires, etc.



  



   The subject of the present invention is a clockwork mechanism allowing digital display, in particular of the indication of the hour or of a date, with increased readability by means of two disks, one indicating for example the units and the other the tens, allowing in particular the display change in an instantaneous manner as well as its rapid correction.



   These displays have often been produced in timepieces and to varying degrees of perfection.



   The present invention, intended mainly for wristwatches, aims to improve these displays by means of a unique mechanism which allows, by its simplicity, total reliability, instant change and the possibility of rapid correction at all times. , including during automatic change.



   This mechanism was made for a date display and its construction was made on an existing movement in order to test its reliability. The results obtained have proved to us the validity of the present invention. Fig. 1 shows, by way of example, a view of the size of the display, object of the present invention, obtained by means of two parallel discs under a dial with a diameter of 27 mm, dimension usually used today. Fig. 2 shows a display obtained on the same dial but through two coaxial discs. Fig. 3 shows the components of the mechanism.

   We can thus see a 24-hour wheel, bearing an elastic finger A and a stopper B, which drives a star of 31 teeth C positioned by its jumper E, the stars carrying the display disks D and U with their jumpers DD and UU, as well as the corrector F and its stop G used for rapid correction.



   The 24-hour wheel, traditionally driven by movement, turns clockwise and by means of its elastic arm A comes into contact with the star C. This arm will arm until it will touch the stop B, from this moment, it is the spring E which bends and the star C begins to turn. The rupture of equilibrium and therefore the advancement of a tooth of star C occurs before contact of the teeth of star C with those of stars U and D.



   The meeting of the teeth of star C with those of stars U and D, carriers of the display discs, allows, in a safe and instantaneous way, thanks to the energy stored by the elastic arm A and the jumper E, much more important than the resistance of the UU and DD jumpers, the advancement of one step of the display.



     The angular positioning which is assigned by the respective jumpers between C and U-D, avoids their contacts before the function, prevents a double jump and contributes to the safety of the mechanism.



   The star C, the centerpiece of the mechanism, has 31 teeth like a normal date wheel but its thickness is not uniform and this characteristic allows it to drive the stars U and D in a particular way.



   To understand how star C and its three stages work, fig. 4 schematically shows a section of the stars of the mechanism.



   The mobile C can be returned from a star from which the thicknesses are subtracted to obtain the various stages, or else be composed of parts machined separately, indexed and then assembled.



   The Zero stage has 31 teeth which are positioned by the jumper E and cooperate with the elastic finger A and the corrector F.



   The Units stage has 30 teeth which cooperate with the stars of the U units, while the Tens stages has 5 teeth which cooperate with the stars D and U.



   Fig. 3 shows the mechanism displaying the date 31 and explains the automatic change that it will operate at midnight. The elastic finger A will arm the spring E and when C advances by one step, tooth 1 will advance star D by one step while tooth 0 will pass under star U without touching it. Result, the tens disc will display 0, and the 1, displayed by the units disc, will remain stationary.



   The next day, when C advances by one step, one of the 30 teeth of its unit stage, in this case tooth 17, will come into contact with the star U and will make it advance by one step, while the tooth 2 will pass under the star D without touching it.



   The additional load of this mechanism on the running of the watch is entirely acceptable, the winding of the elastic arm A is spread over a period of approximately 4 hours.



   The speed of manual correction of this mechanism makes it possible to accept the fact that it is unidirectional and therefore, in the most absolute security.



   The corrector F, rotating only clockwise, advances the star C and therefore the display, if A is in engagement with the star C, the manual force of the correction will cause A to flex without residual damage.



   When resetting the manual time, if A rotates clockwise and F is engaged, F will move away from G without residual damage; if A turns in the opposite direction, it will flex and will not cause any changes to the display.



   The principle of this mechanism being characterized by the mobile counter with selective meshing, it goes without saying that with other numbers of teeth, either on the mobile counter or on the display mobiles, other displays can be produced as the date, examples of jumping hours, time zones, etc.
