Definitions
- the subject of the present invention is a mechanism for rapid correction of date for watch movement.
- Generally manual correction rapid date is made from the winding crown when the latter is in the middle position. Once the winding stem is placed in this axial date correction position the user can, by rotating the winding crown, correct the date.
- the date correction is only obtained for a direction of rotation determined from the winding crown. To correct several steps, or days, from the date, the user must turn the crown between two fingers, release it, then start the operation again.
- the object of the present invention is to provide a mechanism for quick manual correction of the date which allows correction of the date whatever the direction of rotation of the winding crown and even, for a correction of several days, by a rotary movement back and forth of the crown alternately in one direction then in the other, etc.
- the present invention relates to a manual correction mechanism rapid movement of the date of a watch movement which is distinguished by the Features listed in claim 1.
- the single figure of the attached drawing illustrates schematically and by way of example of an embodiment of the rapid correction mechanism of the date according to the invention.
- This figure is a plan view of the mechanism alone, the other elements of the watch movement not being represented.
- the date mechanism of a watch movement includes a date star 1 which is driven one step per day by the watch movement and which carries a mobile date indication.
- a date jumper 2 keeps this date star 1 in a position determined between two successive actuations.
- the manual quick date correction mechanism includes a corrector lever 3 pivoted to 0 on a plate or a movement bridge of watchmaking. This lever has at one of its ends an actuating spout 4 cooperating with the teeth of the date star 1.
- This cam 6 comprises one or more lifts, three in the example illustrated, which, when rotating this cam 6, causes the tilting of the corrector lever 3 and the drive with a step of the date star 1.
- the shape of the lifts of this cam is such that the finger 5 of the correction lever 3 can follow the periphery of this cam 6 which whatever its direction of rotation.
- the lifts of the cam 6 are symmetrical about a radius of the cam passing through the top of the lift.
- This cam 6 is carried by a date correcting wheel 8 connected kinematically by references 9, 10 and 11 to the sliding pinion 12 of the rod watch winder 13 of the clockwork movement when the latter is in the date correction.
- the jumper 2 ensures safe positioning of the star 1.
- Manual correction of the date can be done very quickly by a rotary back and forth movement of the crown that the user holds between two fingers.
- Cam 6 has pointed lifts so if by chance one of these lifted remained in the active position, in contact with the spout 5 of the lever 3, as soon as the winding stem 13 is moved from its middle position, the pinion 12 no longer meshing with the pinion 11, the lever 3 falls back into its rest position illustrated by the action of its return spring.
- the force of the return spring is such that when the connection kinematics 9,10,11 is disengaged from the winding stem 13, the cam 6 is moved under the action of the spout 5 into a position for which this spout 5 is located between two lifts of the cam 6 and for which the other end of the lever is disengaged from the date star.
- This is important because between two quick date corrections, it is imperative that the date star can be indexed every day by one step and therefore not be blocked by the lever 3.
- This quick date correction mechanism is very simple, it facilitates the manipulation to be carried out to correct the date and increases its speed.

Abstract
Description
Claims (5)
- Mécanisme de correction rapide manuelle du quantième d'un mouvement d'horlogerie comportant une tige de remontoir à trois positions axiales et une étoile de quantième, caractérisé par le fait qu'il comporte un levier correcteur (3) basculant comportant un bec (4) à l'une de ses extrémités coopérant avec la denture de l'étoile de quantième (1) et présentant un doigt (5) à son autre extrémité, doigt (5) maintenu à l'aide d'un ressort (7) contre une came (6) présentant au moins une levée et par le fait que cette came (6) est portée par une roue correctrice (8) entraínée par une liaison cinématique (9,10,11) par un pignon coulant (12) de la tige de remontoir (13) lorsque celle-ci est en position axiale intermédiaire de correction du quantième.
- Mécanisme selon la revendication 1, caractérisé par le fait que les levées de la came (6) sont pointues de sorte que lorsque la tige de remontoir est hors de sa position de correction de quantième, la force du ressort (7) provoque le retour du doigt (5) en position de repos entre deux levées de la came (6) de manière à ce que le bec (4) du levier (3) ne soit plus en contact avec l'étoile de quantième.
- Mécanisme selon la revendication 2, caractérisé par le fait que la came (6) comporte trois levées.
- Mécanisme selon la revendication 2 ou la revendication 3, caractérisé par le fait que la ou les levées de la came (6) sont symétriques par rapport à un rayon de la came passant par leur sommet.
- Mécanisme selon l'une des revendications précédentes, caractérisé par le fait que la liaison cinématique reliant la came correctrice (8) au pignon coulant (12) comporte trois renvois (9,10,11).
