L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement d'horlogerie.The invention also relates to a timepiece comprising at least one such watch movement.

Arrière-plan de l'inventionBackground of the invention

Pour effectuer le réglage d'isochronisme d'un ensemble réglant d'horlogerie, en particulier d'un balancier-spiral, il est connu d'agir sur la longueur active du spiral, lequel est attaché à son extrémité intérieure sur une virole solidaire du balancier, et à son extrémité extérieure sur un piton solidaire d'un coq fixé à la platine du mouvement. Pour modifier cette longueur active, et en particulier pour avoir une longueur inférieure à la longueur totale définie par l'encastrement au niveau du piton, on utilise une raquette munie de deux goupilles, ou encore une raquette sur laquelle est rapportée une clé de raquette porteuse de ces deux goupilles. Ces deux goupilles définissent deux portées parallèles, polies, sur lesquelles peut s'appuyer et glisser le spiral, à frottement minimal. A un instant donné, si le spiral s'appuie sur une des goupilles, sa longueur active est celle comprise entre sa fixation à la virole d'une part, et son appui sur cette goupille d'autre part. Si le spiral n'est appuyé sur aucune des goupilles, sa longueur active est égale à sa longueur totale. Si les goupilles sont très écartées, on crée du retard, et l'amplitude de variation est importante, ce qui n'est pas favorable pour une marche régulière. Si elles sont trop rapprochées, on crée de l'avance, et il y a risque de déformation du spiral, ce qui est pire.In order to adjust the isochronism of a timepiece adjusting assembly, in particular of a balance spring, it is known to act on the active length of the hairspring, which is attached at its inner end to a shell integral with the hairspring. pendulum, and at its outer end on a peg secured to a cock attached to the plate of the movement. To modify this active length, and in particular to have a length less than the total length defined by the recess at the peak, is used a racket provided with two pins, or a racket on which is reported a racket key carrier of these two pins. These two pins define two parallel surfaces, polished, on which can support and slide the spiral, minimal friction. At a given moment, if the hairspring relies on one of the pins, its active length is that between its attachment to the ferrule on the one hand, and its support on the pin on the other hand. If the hairspring is not supported on any of the pins, its active length is equal to its total length. If the pins are widely spaced, it creates delay, and the amplitude of variation is important, which is not favorable for a regular walk. If they are too close together, we create a lead, and there is a risk of deformation of the hairspring, which is worse.

L'opérateur ne pouvant visualiser les positions relatives du spiral et des goupilles est obligé de procéder par tâtonnements, ou bien d'utiliser des réglages empiriques, par exemple ajuster les goupilles, quand le balancier est au repos, de façon à ce que le spiral soit centré par rapport aux goupilles, avec un jeu d'une demi-épaisseur de spiral de part et d'autre. Mais, comme tout réglage empirique, il ne représente pas une optimisation du fonctionnement, mais seulement un réglage qu'il est convenu de considérer comme acceptable. De plus, un tel positionnement est théorique, et difficile à réaliser, en raison de l'impossibilité d'introduire des jauges ou similaire pour régler cet écartement.The operator can not visualize the relative positions of the hairspring and pins is forced to proceed by trial and error, or to use empirical settings, for example adjust the pins, when the pendulum is at rest, so that the hairspring is centered with respect to the pins, with a game of half a thickness of spiral on both sides. But, like any empirical setting, it does not represent an optimization of the operation, but only a setting which it is agreed to consider as acceptable. In addition, such positioning is theoretical, and difficult to achieve, because of the impossibility of introducing gauges or the like to adjust this spacing.

La situation se complique avec la combinaison des réglages possibles au niveau du piton et du pivotement de la raquette notamment, et il est difficile pour l'opérateur de maîtriser les phénomènes se produisant réellement au niveau du spiral. Il est donc du plus grand intérêt pour l'opérateur de pouvoir disposer de moyens lui permettant de connaître sa position exacte, pour effectuer les opérations de centrage et de réglage de son battement.The situation is complicated by the combination of possible settings at the piton and the pivoting of the racket in particular, and it is difficult for the operator to control the phenomena actually occurring at the spiral. It is therefore of the greatest interest for the operator to be able to have means enabling him to know his exact position, to perform the operations of centering and adjusting his beat.

Un document de brevet CH408787 au nom de Vuachet, décrit une clé de raquette, qui est constituée par une plaquette pliée en V, venant en appui par des rebords au-dessus d'une lumière radiale que comporte une raquette. Cette plaquette comporte une fente pour le passage du ressort, les bords de cette fente faisant fonction de goupilles pour la délimitation du battement du ressort spiral. L'opérateur peut voir le spiral à travers la lumière radiale de la raquette, mais ne peut appréhender sa position par rapport aux bords de la fente, qui sont masqués par la structure de la plaquette, et qui ne sont pas visibles au travers de la lumière de la raquette.A patent document CH408787 in the name of Vuachet, describes a racket key, which is constituted by a V-folded plate, supported by rims above a radial light that includes a racket. This plate has a slot for the passage of the spring, the edges of this slot acting as pins for the delimitation of the beating of the spiral spring. The operator can see the hairspring through the radial light of the racket, but can not apprehend its position with respect to the edges of the slot, which are masked by the structure of the plate, and which are not visible through the racket light.

Le document de brevet CH40792 Beyner, divulgue une raquette qui comporte deux doigts mobiles qui enserrent le spiral. Ce dernier est visible de dessus entre les deux doigts, toutefois il ne s'agit pas d'une clé de raquette mobile, mais d'un corps de raquette à position fixe, à part son pivotement par rapport à l'axe du spiral, et il n'est pas possible d'agir sur la position angulaire relative entre les goupilles et le ressort.The patent document CH40792 Beyner discloses a racket that has two movable fingers that enclose the spiral. The latter is visible from above between the two fingers, however it is not a mobile racket key, but a racket body with a fixed position, apart from its pivoting relative to the axis of the spiral, and it is not possible to act on the relative angular position between the pins and the spring.

Un document de brevet DE 11 64 931 B au nom de Kienzle Uhrenfabrik AG décrit une raquette qui peut être manoeuvrée sans ouverture de la clé de raquette. Elle comporte une clé de raquette dont la rainure est aussi large que l'épaisseur du spiral. Cette clé est composée de trois bandes minces à chants arrondis, plaquées l'une contre l'autre et coincées dans l'oeil de la raquette, la bande médiane ayant l'épaisseur du spiral et étant décalée des deux autres bandes pour laisser passer le spiral, ces deux autres bandes définissant alors la rainure de passage et de maintien du spiral.A patent document DE 11 64 931 B in the name of Kienzle Uhrenfabrik AG describes a racket that can be maneuvered without opening the racket key. It has a racket key whose groove is as wide as the thickness of the spiral. This key consists of three thin strips with rounded edges, pressed against each other and stuck in the eye of the racket, the middle band having the thickness of the spiral and being offset from the other two bands to let the spiral, these two other bands then defining the groove passage and holding the spiral.

Ces portées de goupilles sont, du moins au niveau des possibles surfaces d'appui du spiral 20, polies pour un appui à frottement minimal d'un tel spiral 20. Tel que visible sur la figure 3, le spiral 20 peut, soit être libre entre les deux portées de goupilles 2 et 3 tel qu'illustré sur la figure, soit porter sur une ou plusieurs des surfaces comprises entre les surfaces 2A et 2B qui délimitent la portée de goupille 2, ou comprises entre les surfaces 3A et 3B qui délimitent la portée de goupille 3.This racket key 1 comprises, parallel to each other in a direction D1 and spaced apart by a distance E, two pin bearings 2 and 3, which are arranged to limit the radial beating of such a spiral 20 inserted between them. These pin bearing surfaces are, at least at the level of the possible bearing surfaces of the spiral 20, polished for a minimum frictional support of such a spiral 20. As visible on the figure 3 , the hairspring 20 may either be free between the two pins 2 and 3 as shown in the figure, or bear on one or more of the surfaces between the surfaces 2A and 2B which delimit the pin bearing 2, or between the surfaces 3A and 3B which define the pin span 3.

La clé de raquette 1 comporte des moyens d'appui sur une telle raquette 10, qui sont agencés pour, en position de montage de la clé de raquette 1 sur une telle raquette 10, ajuster la direction D1 des portées de goupilles 2 et 3 parallèlement à l'axe de pivotement D de la raquette 10.The racket key 1 comprises bearing means on such a racket 10, which are arranged to, in the mounting position of the racket key 1 on such a racket 10, adjust the direction D1 of the pins 2 and 3 pins parallel to the pivot axis D of the racket 10.

Par exemple, ces moyens de maintien sont réalisés sous forme d'une portée sensiblement conique, ou similaire, s'étendant entre la zone d'ajustement 6, laquelle est par exemple réalisée sous forme d'une portée cylindrique d'axe D2, et une portée 8A de diamètre supérieur à celui de la zone d'ajustement 6, pour garantir le maintien de la clé de raquette 1 sur la raquette 10 après chassage.In a preferred embodiment visible on the figure 2 , the pinch holding means 5 comprise a support flange 7 arranged to bear on such a racket 10 on the opposite side to the pins 2 and 3, and a holding surface 8, which is arranged to maintain, on the side pins 2 and 3, the racket key 1 on such a racket 10 after its hunting on the latter. For example, these holding means are made in the form of a substantially conical bearing surface, or the like, extending between the adjustment zone 6, which is for example formed in the form of a cylindrical bearing surface of axis D2, and a range 8A of diameter greater than that of the adjustment zone 6, to ensure the maintenance of the racket key 1 on the racket 10 after driving.

Ainsi, de préférence, la surface de maintien 8 a, selon un plan orthogonal à la direction D2, au moins une section supérieure à celle d'un passage 11 que comporte une telle raquette 10 pour la réception de la clé de raquette 1, et on réalise la zone d'ajustement 6 de profil sensiblement complémentaire à celui de ce passage 11.Thus, preferably, the holding surface 8 has, in a plane orthogonal to the direction D2, at least one section greater than that of a passage 11 that includes such a racket 10 for receiving the racket key 1, and the adjustment zone 6 of profile is made substantially complementary to that of this passage 11.

Pour autoriser ce montage, la clé de raquette 1 est de préférence déformable élastiquement, au moins au niveau de la surface de maintien 8, pour son insertion par chassage dans untel passage 11 que comporte une telle raquette 10 pour la réception de la clé de raquette 1.To allow this mounting, the racket key 1 is preferably elastically deformable, at least at the level of the holding surface 8, for its insertion by driving in such a passage 11 that includes such a racket 10 for receiving the racket key 1.

De façon avantageuse, pour effectuer des réglages, la clé de raquette 1 comporte des moyens de préhension 9, par exemple sous forme de deux portées parallèles pour sa préhension par un outil tel qu'une clé, tel que visible sur les figures 1 et 3, pour sa manoeuvre en pivotement autour d'un axe D2 parallèle à la direction D1 et sensiblement médian par rapport aux portées de goupilles 2 et 3, après son chassage sur une telle raquette 10.Advantageously, to make adjustments, the racket key 1 comprises gripping means 9, for example under form of two parallel spans for its grip by a tool such as a key, as visible on the Figures 1 and 3 , for its maneuver in pivoting about an axis D2 parallel to the direction D1 and substantially median with respect to the pins of pins 2 and 3, after its driving on such a racket 10.

Pour améliorer le confort de travail de l'utilisateur, la clé de raquette 1 comporte avantageusement, dans l'alignement de l'orifice 4, des moyens de réception 40 d'un instrument d'optique comme un alésage 40 tel que visible sur les figures 2 et 3, ou encore un instrument optique de grossissement intégré tel qu'une lentille optique, ou un compte-fils, ou similaire.To improve the working comfort of the user, the racket key 1 advantageously comprises, in the alignment of the orifice 4, receiving means 40 of an optical instrument such as a bore 40 as visible on the Figures 2 and 3 or an integrated magnification optical instrument such as an optical lens, or a son-counter, or the like.

L'invention concerne encore une raquette 10 d'ajustement d'un spiral d'horlogerie 20, laquelle est agencée pour être montée pivotante par rapport à un axe D parallèle à l'axe de pivotement d'un tel spiral 20 ou confondu avec lui, comportant une clé de raquette 1 telle que décrite ci-dessus, chassée sur la raquette 10 de façon à ce que la direction D1 soit parallèle à l'axe D.The invention also relates to a racket 10 for adjusting a clockwork hairspring 20, which is arranged to be pivotally mounted relative to an axis D parallel to the pivot axis of such a hairspring 20 or coinciding with it. , comprising a racket key 1 as described above, driven on the racket 10 so that the direction D1 is parallel to the axis D.

De préférence, cette raquette 10 comporte au moins un passage 11 pour l'insertion et le chassage de la clé de raquette 1. De préférence, la raquette 10 et la clé de raquette 1 sont appairées de façon à ce que ce passage 11 soit de profil sensiblement complémentaire à celui d'une zone d'ajustement 6 que comporte la clé de raquette 1 pour son montage avec serrage sur cette raquette 10.Preferably, this racket 10 comprises at least one passage 11 for the insertion and the hunting of the racket key 1. Preferably, the racket 10 and the racket key 1 are paired so that this passage 11 is of profile substantially complementary to that of an adjustment zone 6 that includes the racket key 1 for mounting clamping on the racket 10.

Avantageusement, pour la mémorisation des réglages, et le suivi en service, la raquette 10 comporte des moyens de repérage 12 gradués pour la détermination de la position angulaire de la clé de raquette 1 autour d'un axe D2 parallèle à la direction D1 et sensiblement médian par rapport aux portées de goupilles 2 et 3 de la clé de raquette 1, laquelle comporte alors des moyens de repérage complémentaire 120, par exemple sous forme d'un index.Advantageously, for the memorization of the settings, and the follow-up in use, the racket 10 comprises registering means 12 graduated for the determination of the angular position of the racket key 1 about an axis D2 parallel to the direction D1 and substantially median relative to the pins 2 and 3 of the racket key 1, which then comprises complementary registration means 120, for example in the form of an index.

Le pivotement de la clé de raquette 1 par rapport à la raquette 10 permet alors un positionnement relatif entre une direction D3 joignant les portées de goupilles 2 et 3, dans un plan perpendiculaire à l'axe D2, et à une direction D4 tangente à la direction locale du ressort 20 dans ce même plan, et l'ajustement de l'angle a que forment entre elles ces deux directions D3 et D4, au voisinage de la valeur de 90°. Il est ainsi possible d'ajuster la clé de raquette 1 de façon à privilégier, selon les observations de l'opérateur et les choix de réglages qu'il décides, des contacts entre le ressort 20 et la clé au niveau de l'une ou l'autre des zones 2A, 2B, 3A, ou 3B.The pivoting of the racket key 1 relative to the racket 10 then allows a relative positioning between a direction D3 joining the pins of pins 2 and 3, in a plane perpendicular to the axis D2, and a direction D4 tangent to the local direction of the spring 20 in the same plane, and the adjustment of the angle a that form between them these two directions D3 and D4, in the vicinity of the value of 90 °. It is thus possible to adjust the racket key 1 so as to favor, according to the observations of the operator and the choice of settings that he decides, contacts between the spring 20 and the key at the level of one or the other of areas 2A, 2B, 3A, or 3B.

Dans une variante particulière, la raquette 10 comporte une fente 13, sensiblement radiale par rapport à l'axe de pivotement D de la raquette 10. Cette fente 13 sert de surface de réception pour la clé de raquette 1, et ses flancs constituent un passage 11 avec lequel coopère une zone d'ajustement 6 que comporte la clé de raquette 1. La raquette 10 peut alors comporter d'autres moyens de repérage radial 14 pour la mémorisation de la position radiale de la clé de raquette 1, de façon complémentaire avec des moyens de repérage complémentaire de la clé de raquette 1, par exemple sous forme d'un index non représenté sur les figures.In a particular variant, the racket 10 comprises a slot 13, substantially radial with respect to the pivot axis D of the racket 10. This slot 13 serves as a receiving surface for the racket key 1, and its flanks constitute a passage 11 with which cooperates an adjustment zone 6 that includes the racket key 1. The racket 10 may then include other radial locating means 14 for storing the radial position of the racket key 1, in a complementary manner with complementary marking means of the racket key 1, for example in the form of an index not shown in the figures.

La figure 1 illustre une pièce d'horlogerie 50, comportant un mouvement d'horlogerie 40. Celui-ci comporte une platine 43, laquelle supporte un coq 42 pour le maintien d'un ensemble réglant 30, comportant typiquement un ensemble balancier-spiral. Ce dernier comporte un ressort spiral 20, qui est attaché par sa dernière spire 21, à son extrémité, à un piton 41 solidaire du coq 42. Cette dernière spire 21 du ressort 21 est, à distance du piton 41, enfilée entre les deux portées de goupilles 2 et 3 de la clé de raquette selon l'invention, elle-même montée sur une raquette 10.The figure 1 illustrates a timepiece 50, comprising a clockwork movement 40. It comprises a plate 43, which supports a cock 42 for the maintenance of a regulating assembly 30, typically having a balance-spiral assembly. The latter comprises a spiral spring 20, which is attached by its last turn 21, at its end, to a stud 41 integral with the cock 42. The latter turn 21 of the spring 21 is, at a distance from the stud 41, threaded between the two spans pins 2 and 3 of the racket key according to the invention, itself mounted on a racket 10.

Ainsi l'invention concerne encore un ensemble réglant 30 pour mouvement d'horlogerie, comportant au moins un spiral 20 pivotant autour d'un axe de pivotement, et maintenu par une telle clé de raquette 1, ou par une telle raquette 10, agencé de façon à ce que la direction D1 soit parallèle à l'axe de pivotement du spiral 20.Thus, the invention also relates to a setting device 30 for a watch movement, comprising at least one spiral pivoting around of a pivot axis, and held by such a racket key 1, or by such a racket 10, arranged so that the direction D1 is parallel to the pivot axis of the spiral 20.
