Plus particulièrement, cette extrémité extérieure 6 est mobile avec du jeu dans le deuxième logement 76.More particularly, the elastic return means 3 is a spring, an outer end 6 of which is housed in a second housing 76 that comprises the stopper 7. More particularly, this outer end 6 is movable with play in the second housing 76.

Plus particulièrement, le moyen de rappel élastique 3 est un ressort qui comporte une spire 51, laquelle est agencée pour venir au contact du premier logement 71 de l'arrêtoir 7 dans la position armée selon une large zone de contact ZC d'une amplitude angulaire supérieure à 10° par rapport à l'axe D, et pour rester à distance du premier logement 71 dans la position désarmée.More particularly, the elastic return means 3 is a spring which comprises a coil 51, which is arranged to come into contact with the first housing 71 of the stopper 7 in the armed position according to a large contact zone ZC of an angular amplitude greater than 10 ° relative to the axis D, and to remain at a distance from the first housing 71 in the disarmed position.

De préférence, ce premier logement 71 est constitué par un alésage, ou un chambrage, ou un lamage, sur au moins une partie angulaire susceptible d'être en contact avec la ou les spires du ressort. Par exemple, les figures montrent un premier logement 71 constitué par un chambrage sur environ 355°, et qui est dégagé sur un angle au centre d'environ 5° pour permettre le passage de l'extrémité externe du ressort 6 et son insertion dans le deuxième logement 76.Preferably, this first housing 71 is formed by a bore, or a recess, or a counterbore, on at least one angular part capable of being in contact with the coil or turns of the spring. For example, the figures show a first housing 71 constituted by a recess over approximately 355 °, and which is cleared over an angle at the center of approximately 5 ° to allow the passage of the outer end of the spring 6 and its insertion into the second accommodation 76.

Plus particulièrement, l'arrêtoir 7 comporte une lumière oblongue 9 dans laquelle est logé le moyeu 2 et qui autorise une mobilité radiale de l'arrêtoir 7 par rapport au moyeu 2 pour modifier la position radiale du doigt d'arrêt 8 périphérique que comporte l'arrêtoir 7.More particularly, the stopper 7 comprises an oblong slot 9 in which the hub 2 is housed and which allows radial mobility of the stopper 7 relative to the hub 2 in order to modify the radial position of the peripheral stop finger 8 that the device comprises. stopper 7.

Plus particulièrement, ce mécanisme 100 est un mécanisme de quantième.More particularly, this mechanism 100 is a date mechanism.

La figure 7 expose ce cas particulier et non limitatif d'un mécanisme de quantième. Lors d'une correction de date par l'utilisateur, une dent 108 de l'indicateur de quantième 110, tournant dans le sens horaire de la flèche sur cette figure, pousserait le doigt 8, commandant ainsi le débrayage et le changement de position relatif du moyeu 2 par rapport à l'oblong 9 lors du retrait radial du doigt 8 sous l'action de poussée exercée par une dent 108, tel que visible sur la figure 4 ; après le passage de la dent 108, le ressort 3 ramène le doigt 8 dans la position illustrée par la figure 7 ; ce doigt 8 entraînera une dent 108 lors du prochain changement de date.The figure 7 describes this particular and non-limiting case of a date mechanism. During a date correction by the user, a tooth 108 of the date indicator 110, rotating in the clockwise direction of the arrow in this figure, would push the finger 8, thus controlling the disengagement and the relative change of position. of the hub 2 relative to the oblong 9 during the radial withdrawal of the finger 8 under the thrust action exerted by a tooth 108, as visible on the figure 4 ; after the passage of the tooth 108, the spring 3 returns the finger 8 to the position illustrated by the figure 7 ; this finger 8 will drive a tooth 108 during the next date change.

L'invention concerne encore une pièce d'horlogerie 1000 comportant au moins un tel mécanisme d'affichage d'horlogerie à saut semi-instantané 100, en particulier avec des moyens de commande 500. Plus particulièrement, cette pièce d'horlogerie 1000 est une montre.The invention also relates to a timepiece 1000 comprising at least one such semi-instantaneous jump clock display mechanism 100, in particular with control means 500. More particularly, this timepiece 1000 is a watch.

En somme, l'invention permet de sécuriser un mécanisme fragile, car elle réduit le risque de casse des éléments ressorts puisque la butée se fait sur une large zone d'appui du ressort, tout en procurant un gain sensible sur l'encombrement par rapport aux mécanismes existants. Le maintien des propriétés élastiques du ressort est garanti. L'invention garantit une meilleure maîtrise des forces. Le mécanisme selon l'invention emmagasine de l'énergie de manière maîtrisée, avec un armage angulaire précis.In short, the invention makes it possible to secure a fragile mechanism, because it reduces the risk of breakage of the spring elements since the stop is made on a large bearing area of the spring, while providing a significant gain in the size compared to to existing mechanisms. The maintenance of the elastic properties of the spring is guaranteed. The invention guarantees better control of the forces. The mechanism according to the invention stores energy in a controlled manner, with precise angular winding.
