Parallèlement, le mobile d'entraînement 14 engrène aussi avec un pignon de renvoi 15 solidaire d'une roue de renvoi 16 entraînant le pignon de verrou 9. Ainsi, ce dernier tourne également en sens antihoraire (comme également représenté par la flèche à la
La rotation de la roue d'armage 1, en entraînant le centre 3 du spiral 2, permet d'armer celui-ci, du moins, lorsque l'extrémité distale 4 du spiral 2 est immobile. Cette situation est représentée en particulier sur la

La rotation du pignon de verrou 9 continue toujours dans le sens antihoraire, ce qui a pour conséquence que la goupille 10 revient progressivement à sa position initiale 22 dans le trou oblong 11, c'est-à-dire celle située à l'extrémité opposée, par rapport à la position finale 21, de l'arc de cercle formé par le trou oblong 11 (cf.

Le pignon de renvoi 15 et sa roue de renvoi 16 sont de préférence montés coaxialement sur un axe en prévoyant une liaison par friction, ce qui permet un ajustement précis du moment de la libération du mobile de sortie 6.The
La virole 3 comprend préférentiellement plusieurs trous de positionnement 17 pour les goupilles de fixation 18. Ainsi, il est possible de plus ou moins préarmer le spiral 2, en changeant de trous de positionnement 17 recevant les goupilles de fixation 18, ce qui se traduit par un déplacement angulaire de la virole 3 par rapport à la roue d'armage 1 et donc à une modification de l'intensité de l'armage du spiral 2.The
Le mécanisme selon l'invention peut être utilisé dans toutes sortes d'applications. L'homme du métier peut l'adapter aisément en modifiant la taille des pièces, les rapports d'engrenage, le nombre de roues de renvoi, le nombre de dents 13 du mobile de sortie 6, etc.The mechanism according to the invention can be used in all kinds of applications.

La libération du mobile de sortie se produit instantanément, c'est pour cette raison qu'on emploie l'expression « saut instantané ». Ce saut peut être mis en oeuvre dans des mécanismes variés, notamment d'affichage des dizaines de minutes et des heures. Ainsi, si le mobile d'entraînement est le mobile des unités d'une pièce d'horlogerie, sa vitesse est de 1/5ème de tour par minute, la vitesse du verrou 8 est de 1 tour par minute et le cycle décrit ci-dessus se produit toutes les minutes.The release of the mobile output occurs instantly, it is for this reason that the term "instant jump" is used. This jump can be implemented in various mechanisms, including display tens of minutes and hours. Thus, if the driving wheel is the mobile units of a timepiece, its speed is 1/5 th of a minute, the speed of the
Le faible couple résistif du mécanisme de saut selon l'invention permet d'entraîner un dispositif d'affichage des minutes lourd et volumineux sans trop altérer le fonctionnement du mouvement de base. Sur le mobile de sortie peut par exemple venir se fixer une cage des minutes composée de deux ponts et de cinq mobiles supportant les disques des minutes. La cage des minutes peut être maintenue entre une platine et un pont baguette.The low resistive torque of the jump mechanism according to the invention makes it possible to drive a device for displaying the heavy and bulky minutes without unduly altering the operation of the basic movement. On the mobile output can for example come to set a cage of minutes composed of two bridges and five mobiles supporting the minutes disks. The minute cage can be held between a turntable and a stick bridge.
