Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne un mécanisme correcteur 1 pour un mécanisme d'affichage de quantième 10 d'horlogerie, lequel comporte un mobile d'affichage 11.The invention relates to a corrector mechanism 1 for a clock calendar display mechanism, which comprises a display unit 11.

Le mécanisme correcteur 1 est agencé pour modifier la position angulaire de ce mobile d'affichage 11.The corrective mechanism 1 is arranged to modify the angular position of this display mobile 11.

Le mécanisme correcteur 1 comporte, d'une part un mobile de commande 2 agencé pour être commandé par une action d'un utilisateur ou/et par un mécanisme d'horlogerie 100, et d'autre part un mobile de sortie 3 agencé pour coopérer avec un tel mobile d'affichage 11.The corrective mechanism 1 comprises, firstly a control mobile 2 arranged to be controlled by an action of a user and / or by a mechanism timepiece 100, and secondly an output mobile 3 arranged to cooperate with such a display mobile 11.

Selon l'invention, ce mécanisme correcteur 1 comporte un mécanisme de roue libre, qui est agencé pour débrayer le mobile de sortie 3 du mobile de commande 2 dans un premier sens relatif de rotation, et à embrayer le mobile de sortie 3 avec le mobile de commande 2 dans un deuxième sens relatif de rotation opposé au premier sens relatif de rotation.According to the invention, this corrective mechanism 1 comprises a freewheel mechanism, which is arranged to disengage the mobile output 3 of the control wheel 2 in a first relative direction of rotation, and to engage the mobile output 3 with the mobile 2 in a second relative direction of rotation opposite to the first relative direction of rotation.

Plus particulièrement 1, ce mobile de commande 2, ou respectivement ce mobile de sortie 3, est solidaire en rotation d'un rotor 4. Le mobile de sortie 3 ou respectivement le mobile de commande 2 comporte une cavité 30, dans laquelle est mobile en pivotement ce rotor 4. Et ce rotor 4 et/ou cette cavité 30 comporte au moins une première chambre 5, 50, de section variable radialement par rapport à l'axe de pivotement D du rotor 4.More particularly 1, this control mobile 2, or respectively this mobile output 3, is integral in rotation with a rotor 4. The output mobile 3 or respectively the control mobile 2 comprises a cavity 30, in which is movable in this rotor 4 is pivoted. And this rotor 4 and / or this cavity 30 comprises at least a first chamber 5, 50, of variable section radially with respect to the pivot axis D of the rotor 4.

Et ce mécanisme correcteur 1 comporte au moins un mobile fou 6, tel qu'une bille, un rouleau, ou autre, enfermé dans une telle chambre 5, 50, et dont les dimensions sont agencées pour autoriser sa liberté dans cette chambre 5, 50, dans le premier sens relatif de rotation du rotor 4 par rapport à la cavité 30, et pour provoquer son blocage sur une paroi de la chambre 5, 50, dans le deuxième sens relatif de rotation du rotor 4 par rapport à la cavité 30.And this corrective mechanism 1 comprises at least one crazy mobile 6, such as a ball, a roller, or the like, enclosed in such a chamber 5, 50, and whose dimensions are arranged to allow its freedom in this chamber 5, 50 in the first relative direction of rotation of the rotor 4 relative to the cavity 30, and to cause it to be blocked on a wall of the chamber 5, 50, in the second relative direction of rotation of the rotor 4 with respect to the cavity 30.

Dans une variante, le mobile fou 6 est mobile seulement dans un plan perpendiculaire à l'axe de pivotement D du rotor 4.In a variant, the idler 6 is movable only in a plane perpendicular to the pivot axis D of the rotor 4.

Dans une autre variante, le mobile fou 6 est mobile seulement parallèlement à l'axe de pivotement D du rotor 4.In another variant, the idler 6 is mobile only parallel to the pivot axis D of the rotor 4.

Dans une autre variante encore, le mobile fou 6 est mobile à la fois dans un plan perpendiculaire à l'axe de pivotement D du rotor 4 et parallèlement à l'axe de pivotement D du rotor 4.In yet another variant, the idler 6 is mobile both in a plane perpendicular to the pivot axis D of the rotor 4 and parallel to the pivot axis D of the rotor 4.

Selon une caractéristique particulière, la surface périphérique 40 du rotor 4 constitue, dans chaque chambre 5, une came dans un plan perpendiculaire à un axe de rotation D commun au mobile de sortie 3 et au rotor 4.According to a particular characteristic, the peripheral surface 40 of the rotor 4 constitutes, in each chamber 5, a cam in a plane perpendicular to an axis of rotation D common to the output mobile 3 and to the rotor 4.

Selon une autre caractéristique particulière, la surface périphérique 40 du rotor 4 constitue, dans chaque chambre 5, une came selon une direction parallèle à un axe de rotation D commun au mobile de sortie 3 et au rotor 4.According to another particular characteristic, the peripheral surface 40 of the rotor 4 constitutes, in each chamber 5, a cam in a direction parallel to an axis of rotation D common to the output mobile 3 and to the rotor 4.

Selon encore une autre caractéristique particulière, la surface périphérique 40 du rotor 4 constitue, dans chaque chambre 5, une came à la fois dans un plan perpendiculaire à un axe de rotation D commun au mobile de sortie 3 et au rotor 4, et selon une direction parallèle à l'axe de rotation D.According to yet another particular characteristic, the peripheral surface 40 of the rotor 4 constitutes, in each chamber 5, a cam at a time in a plane perpendicular to an axis of rotation D common to the output mobile 3 and the rotor 4, and in a direction parallel to the axis of rotation D.

Plus particulièrement, et tel que visible sur la figure 5, chaque chambre 5, 50, comporte, dans le même sens circonférentiel que toutes les autres chambres 5, 50, une zone d'élargissement progressif au niveau d'une surface inclinée 7, suivie d'une zone élargie limitée par une surface de butée 8. Et le mobile fou 6 est libre dans la zone élargie dans le premier sens relatif de rotation, et vient en appui de blocage sur la surface inclinée 7 dans le deuxième sens relatif de rotation.More particularly, and as visible on the figure 5 each chamber 5, 50 has, in the same circumferential direction as all the other chambers 5, 50, a progressive enlargement zone at an inclined surface 7, followed by an enlarged zone bounded by an abutment surface 8. And the idler 6 is free in the enlarged area in the first relative direction of rotation, and comes into blocking support on the inclined surface 7 in the second relative direction of rotation.

Plus particulièrement, chaque mobile fou 6 est une bille. Dans d'autres variantes non illustrées, les mobiles fous 6 peuvent prendre d'autres formes : des éléments bloquants non roulants mais seulement glissants, de type coins, à condition d'en assurer le déblocage, ou encore des géométries qui ne sont pas strictement de révolution, par exemple des pignons fous. Une autre variante, à l'inverse, concerne un maintien magnétique d'un mobile fou 6, notamment une bille, sur l'une des cages, et combinaison avec une came imprimant un effort permettant le décollage et le changement de position: la came ne sert alors plus au maintien, mais au déblocage.More particularly, each idler 6 is a ball. In other non-illustrated variants, the crazy mobiles 6 may take other forms: non-rolling blocking elements but only slippery, of the wedge type, provided that they are unlocked, or else geometries that are not strictly of revolution, for example crazy gears. Another variant, conversely, relates to a magnetic holding of an idler 6, in particular a ball, on one of the cages, and combination with a cam printing a force allowing the takeoff and the change of position: the cam then no longer serves to maintain, but to unlock.
