Definitions
- the subject of the invention is a downshifting display mechanism.
- rake driven by sprockets with teeth truncated.
- These rake mechanisms include a rake rotating on an axis, a display needle being integral with the rake.
- the rake is a piece relatively large, so these mechanisms occupy an important place in a timepiece.
- the cam revolves around a axis, and is integral with a needle. The cam is based on the data we want display, and present at the end of the race a part right which will allow the probe to return to its initial position under the action of a spring.
- the object of the present invention is to achieve a retrograde display mechanism, which take up little space, while being safe operation.
- the display mechanism downshifts according to the invention is characterized in that it comprises a star secured to a toothed drive wheel, a succession of points constituting the star, each having a flank against which a feeler attached to a needle is supported by the action of a spring, the sides being adapted and dimensioned in function of the data to be displayed.
- the probe, the needle and the spring are mounted on a barrel turning on an axis.
- the mechanism includes a stop which blocks the barrel's return rotation, after the probe has finished its race on the side of the point of the star, and falls on the next flank for a new cycle.
- the sides of the points of the star can be trained and sized to achieve a linear display.
- the drive of the retrograde mechanism is made via wheels R1 and R2.
- the retrograde star 1 is integral with the wheel R2 and has several identical spikes regularly distributed around its periphery.
- the beak of the retrograde probe 3 is continuously in contact with a tip of the retrograde star 1 resting on the side B of said point. Indeed, the spiral spring 2 maintains this permanent contact.
- On the cup of axis A (figure 2), we can see the detail of the mechanism.
- the spiral spring 2 is integral with the canon 7.
- the retrograde probe 3 and the needle 6 are driven out on this same barrel 7. It is free on axis A.
- Pin 4 is used to hold the spiral spring 2.
- the mobile retrograde R2 rotates clockwise, causing the spout of the retrograde probe 3 via the flank B.
- the beak reaches the end of its travel ( Figure 3)
- it releases the probe which falls on the next flank C. And so on on the side C to the next. Therefore the needle is in continuous movement.
- the pin 5 acts as a stop during the jump, and prevents the beak of the retrograde probe 3 does not come to the bottom in profile of the retrograde star 1.
- flanks B, C, of the points of the star of retrograde 1 are judiciously adapted so that retrograde needle 6 moves linearly on a dial not shown.
- the spring hairspring 2, retrograde feeler 3, and needle 6 are driven out of barrel 7, and are by therefore fixed in their respective positions on said canon 7.
- Spiral spring 2 is under tension and fixed to the frame of the mechanism using the pin 4.
- the needle 6 is at the start of its race against stop 5 and the retrograde probe 3 also at the start of its stroke in contact with the flank B of a point of the retrograde star 1.
- the star 1 attached to the wheel R2 is driven according to the arrow (see Figures 1 and 3) by the mobile R1, and leads to its turn probe 3, which, as and the advance of the wheel R1, moves along the sidewall B of the point of the star 1.
- the needle 6 which is in a fixed position relative to the probe, is driven by said probe 3 against the action of spring 2, and indicates the values displayed on the dial not shown.
- the spring 2 brings back the probe 3 and the needle 6 in their starting position in abutment against the stop 5, and the cycle can start again on the flank C of star 1.
- the mechanism which has just been described in see Figures 1 to 4, can be adapted for indicate any data usually displayed by a timepiece, including seconds, minutes, hours, dates, days, phases of the moon, etc ... for this to adequately size the mobile R1 and R2, and adapt the tips of the star 1 with the values you want to display.
- the device described offers the advantage of being simple and to propose a display always in movement. Indeed, as soon as the probe passes a tip of the star, the next cycle starts and the display continues without interruption.

Abstract
Description
Dans le dessin :
- la figure 1 représente une vue de dessus du mécanisme,
- la figure 2 est une vue en coupe à travers l'axe portant l'aiguille du mécanisme,
- la figure 3 est une vue semblable à celle de la figure 1, le palpeur de rétrograde étant dans une position extrême précédent la remise à zéro de l'aiguille, et
- la figure 4 est une vue de dessus de l'étoile de rétrograde.
Le mécanisme comprend :
- une étoile rétrograde 1,
- un ressort spiral 2,
- un palpeur rétrograde 3,
- une goupille de fixation du ressort spiral4,
- une goupille de butée 5, et
- une aiguille 6
Claims (4)
- Mécanisme d'affichage rétrogradant, caractérisé en ce qu'il comprend une étoile (1) solidaire d'une roue d'entraínement, une succession de pointes constituant l'étoile présentant chacune un flanc (B, C, ..) contre lequel un palpeur (3) solidaire d'une aiguille (6) s'appuie, sous l'action d'un ressort (2), les flancs (B, C, ..) étant adaptés et dimensionnés en fonction de la donnée à afficher.
- Mécanisme selon la revendication 1 caractérisé en ce que le palpeur (3), l'aiguille (6), et le ressort (2) sont montés sur un canon (7) tournant sur un axe.
- Mécanisme selon la revendication 2 caractérisé en ce qu'une butée (5) bloque la rotation de retour du canon (7) sous l'action du ressort (2) après que le palpeur ait terminé sa course sur le flanc(B,C,..), et retombe sur le flanc suivant pour un nouveau cycle.
- Mécanisme selon la revendication 1, caractérisé en ce que les flancs (B, C, ..) des pointes de l'étoile (1) sont formés de manière à réaliser un affichage linéaire.
