Description
L'invention concerne un mouvement d'horlogerie comportant au moins une platine et un pont pour le maintien de part et d'autre d'un mobile dont un pivot inférieur occupe une position de référence sur ladite platine, où ledit mouvement comporte des moyens de réglage en hauteur d'au moins un premier point dudit pont par rapport à ladite platine selon la direction de l'axe de rotation dudit mobile, ledit premier point étant, en projection sur un plan de référence de ladite platine orthogonal audit axe de rotation dudit mobile, à une première distance non nulle de ladite position de référence.The invention relates to a clockwork movement comprising at least one plate and a bridge for holding on either side of a mobile, a lower pivot of which occupies a reference position on said plate, where said movement comprises means for height adjustment of at least a first point of said bridge relative to said plate in the direction of the axis of rotation of said moving body, said first point being in projection on a reference plane of said plate orthogonal to said axis of rotation of said mobile, at a first non-zero distance from said reference position.
L'invention concerne encore une montre comportant au moins un tel mouvement.The invention also relates to a watch comprising at least one such movement.
L'invention concerne le domaine des instruments mécaniques de précision, et plus précisément d'horlogerie. Elle concerne en particulier des mouvements d'horlogerie comportant des mobiles pivotés entre deux éléments de structure.The invention relates to the field of precision mechanical instruments, and more precisely watchmaking. It relates in particular to watch movements comprising mobile rotated between two structural elements.
Le réglage de l'ébat d'un mobile horloger pivoté entre deux éléments de structure, notamment entre une platine et un pont, aussi dit coq notamment dans le cas d'un pont de balancier, permet souvent d'optimiser son fonctionnement, ainsi que la performance du mouvement dans lequel il est intégré. Souvent, cet ébat n'est pas réglable, et résulte des tolérances de fabrication et des jeux fonctionnels. Pour surmonter cette absence de plage de réglage, un horloger expérimenté sait effectuer une déformation locale d'un des composants de l'assemblage, le moins rigide, par exemple le coq, pour effectuer un réglage d'ébat, par exemple selon une amplitude de 20 à 40 micromètres pour un réglage d'ébat de balancier au T1.The setting of the frog of a clock mobile pivoted between two structural elements, in particular between a plate and a bridge, also called cock, especially in the case of a balance bridge, often makes it possible to optimize its operation, as well as the performance of the movement in which it is integrated. Often, this frolicking is not adjustable, and results from manufacturing tolerances and functional games. To overcome this lack of adjustment range, an experienced watchmaker knows how to perform a local deformation of one of the components of the assembly, the least rigid, for example the rooster, to perform a frolicking, for example according to an amplitude of 20 to 40 micrometers for a rocking balance at T1.
Cette manipulation est délicate, approximative, coûteuse en temps, nécessite du personnel de haute qualification, et n'est pas reproductible ni automatisable.This manipulation is delicate, approximate, costly in time, requires highly qualified personnel, and is not reproducible or automated.
L'autre option consiste à modifier manuellement la position relative d'un pont par rapport à une platine, et notamment de modifier la position d'un amortisseur porte-palier que comporte la platine, par rapport au pont, ou inversement, ce qui nécessite un déchassage, et entraîne, comme dans le cas précédent, une influence sur la force de tenue de l'amortisseur, ou/et une déformation d'au moins un des composants, ce qui n'est pas souhaitable.The other option is to manually change the relative position of a bridge relative to a platen, and in particular to change the position of a bearing damper that comprises the plate, relative to the bridge, or vice versa, which requires a disengagement, and causes, as in the previous case, an influence on the holding force of the damper, and / or a deformation of at least one of the components, which is undesirable.
Un réglage mécanique est donc préférable, car il permet de pallier les défauts de répétitivité, et est accessible à du personnel moins hautement qualifié, et est automatisable. Toutefois, l'espace disponible dans un calibre ne permet en général pas de loger un mécanisme de réglage supplémentaire, tout particulièrement dans la direction de l'épaisseur du mouvement selon laquelle un tel réglage d'ébat doit en général être effectué.A mechanical adjustment is therefore preferable because it makes it possible to overcome the defects of repetitiveness, and is accessible to less highly qualified personnel, and is automatable. However, the space available in a caliber generally does not accommodate an additional adjustment mechanism, especially in the direction of the thickness of the movement in which such frolicking setting is generally to be performed.

Le pont 3 peut, selon la réalisation du mouvement 1, encadrer le mobile 4 de part et d'autre de son axe de rotation D0, ou bien être monté en porte-à-faux d'un seul côté de cet axe D0 ; dans cette configuration, on utilise la désignation de pont balancier traversant. La fixation du pont 3 sur la platine 2, et son bon positionnement relatif par rapport à celle-ci, nécessitent un serrage de bonne qualité, qui est réalisé de préférence par au moins un moyen de serrage tel qu'une vis, et au moins une référence de positionnement telle que vis avec portée de pivot, pion de centrage, ou similaire. De préférence la référence de positionnement comporte un élément de centrage, tel que pivot ou pion dans une goutte ou un alésage, ou inversement, et un élément d'alignement, tel qu'un pion dans une lumière alignée avec l'élément de centrage, ou inversement. Qu'il s'agisse d'un coq ou d'un pont balancier traversant le système de centrage et d'alignement reste identique.The
Dans la version illustrée par les figures, le mouvement 1 comporte une vis de serrage 35 coopérant avec un taraudage 25 de la platine 2, selon un axe rectiligne D2 sensiblement parallèle à l'axe de rotation D0 du mobile 4, pour le serrage en appui du pont 3 sur le poussoir 9. Ce taraudage 25 est positionné dans une position P2, à une deuxième distance L2 non nulle de la position de référence P0 du mobile 4. De préférence, cette deuxième distance L2 est différente de la première distance L1. Dans une version préférée illustrée par les figures, l'axe rectiligne D9 du logement 29 et l'axe rectiligne D2 du taraudage 25 sont coplanaires avec l'axe de rotation D0 du mobile 4.In the version illustrated by the figures, the
Dans une variante particulière, le mouvement 1 comporte une vis de pivot 36 coopérant avec un taraudage 26 de la platine 2 selon un axe rectiligne de pivotement D6 sensiblement parallèle à l'axe de rotation D0 du mobile 4, pour autoriser un réglage angulaire du pont 3 par rapport à la platine 2 autour de cet axe rectiligne de pivotement D6, et pour le serrage en appui, dans une position angulaire déterminée, du pont 3 sur la platine 2 . Ce taraudage 26 est positionné à une troisième distance L3 non nulle de la position de référence P0. Dans cette même variante, le mouvement 1 comporte de préférence des moyens micrométriques de réglage angulaire 60 pour le réglage angulaire relatif du pont 3 par rapport à la platine 2. Et, quand le pont 3 comporte une surface de réception 39 du poussoir 9, cette surface de réception 39 est avantageusement limitée par des surfaces de butée qui limitent la course angulaire de réglage angulaire relatif du pont 3 par rapport à la platine 2, et la vis de serrage 35 prend appui sur une surface plane du pont 3, ou dans une rainure plane 37 du pont 3 délimité par des surfaces de butée. Dans un exemple particulier, ces moyens micrométriques de réglage angulaire 60 comportent une vis 61 logée dans un taraudage 21 sensiblement radial de la platine 2, ou respectivement dans un taraudage 31 sensiblement radial du pont 3, et cette vis 61 est agencée pour repousser ou tirer un doigt 62 solidaire du pont 3, ou respectivement de la platine 2, par exemple au niveau d'une gorge 63 que comporte la vis 61, ou similaire.In a particular variant, the

La vis sans fin 75 entraîne une couronne 81 prisonnière dans un alésage borgne 82 de la platine 2, dans laquelle elle est enfermée par la tête 83 d'un poussoir 84 qui constitue le poussoir 9. La couronne 81 comporte une denture externe 85 qui coopère avec la vis sans fin 75, et un taraudage interne 86, qui coopère avec un filetage 87 du poussoir 84. Ce poussoir comporte deux plats 88 qui l'immobilisent en rotation dans une lumière oblongue 89 de la platine 2. De ce fait le poussoir 84 est mobile selon la direction Z de l'axe D9 commun à la couronne 81 et au poussoir 84, quand on manoeuvre la vis sans fin 75, par exemple par un outil dans une fente 75A.The
Dans une variante avantageuse, une précontrainte par des moyens de précontrainte 90, représentés sous forme d'un ressort hélicoïdal sur la
De préférence, la vis sans fin 75 comporte une portée cylindrique 75B pour son guidage dans un alésage 377 de la platine 2.Preferably, the
Le montage de l'ensemble est aisé: on monte d'abord le poussoir 84 dans la couronne 81, on les dépose dans leur logement 82 en indexant le poussoir 84 de façon à guider ses plates 88 dans la rainure oblongue 89, puis on vient visser la vis sans fin 75, la mettre en position de butée sur la face 277 de la platine 2, puis on chasse la goupille d'arrêt 79, avant de poser le pont 3.The assembling of the assembly is easy: the
Le mouvement 1 selon l'invention est conçu pour un réglage facile au moment de la mise au point, et à cet effet les moyens de commande 7 sont de préférence situés en périphérie de la platine 2, et sont accessibles après assemblage du mouvement 1 complet. De la même façon, quand le mouvement 1 comporte des moyens micrométriques de réglage angulaire 60, ceux-ci sont également situés en périphérie de la platine 2 ou du pont 3, et sont accessibles après assemblage du mouvement 1 complet.The
L'invention concerne encore une montre 100 comportant au moins un tel mouvement 1.The invention also relates to a
L'invention permet ainsi d'éviter toute déformation du coq, de réutiliser des composants existants par des usinages simples, de ne rajouter que des composants très simples tels que billes, vis, ou similaires, d'effectuer des réglages d'ébat précis, rapides, reproductibles, et automatisables, grâce à l'accessibilité d'une vis pointeau en périphérie de la platine. De plus, cette conception dans l'épaisseur de la platine (ou de la platine et du coq) n'introduit, au voisinage du mobile dont on veut régler l'ébat, aucun élément susceptible de venir en interférence ou en collision avec un composant voisin voire le mobile lui-même.The invention thus makes it possible to avoid any deformation of the rooster, to reuse existing components by simple machining, to add only very simple components such as balls, screws, or the like, to make adjustments. Precise, fast, reproducible, and automatable, thanks to the accessibility of a needle screw at the periphery of the plate. In addition, this design in the thickness of the plate (or platinum and rooster) introduces, in the vicinity of the mobile which we want to adjust the frolicking, any element likely to come into interference or collision with a component neighbor or even the mobile itself.
Le mécanisme est simple, est facilement intégrable dans les mouvements existants, et procure un pouvoir réglant élevé.The mechanism is simple, easily integrable into existing movements, and provides high control power.
