There is a control rod (12) mounted on an annular groove (14) having a length l, an external diameter D, an internal diameter d, mounted movably in translation in the frame along the first axis AA'. There is a fixing plate (20) mounted on the frame parallel to this plane and having a locking piece (22) movably mounted in rotation about a second axis BB' perpendicular to the reference plane and cooperating with this rod by engagement in the groove for limiting its displacement in translation.

Description

La présente invention se rapporte aux mécanismes de commande d'une pièce d'horlogerie du type comportant :

  • un bâti, muni de deux faces parallèles, dont l'une est destinée à porter un cadran et l'autre se trouve en regard du fond,
  • une tige de commande, montée mobile en translation sur le bâti et comportant une gorge annulaire, et
  • une plaque de maintien montée mobile sur le bâti.
The present invention relates to control mechanisms for a timepiece of the type comprising:
  • a frame, provided with two parallel faces, one of which is intended to carry a dial and the other is located opposite the bottom,
  • a control rod, mounted movable in translation on the frame and comprising an annular groove, and
  • a retaining plate movably mounted on the frame.

Plus particulièrement, l'invention concerne les mécanismes de mise à l'heure pour lesquels la tige de commande est une tige de mise à l'heure et la plaque de maintien est une tirette.More particularly, the invention relates to time-setting mechanisms for which the control rod is a time-setting rod and the holding is a zipper.

Dans ces pièces d'horlogerie, la commande se fait par un mouvement de translation et de rotation de la tige, par l'intermédiaire d'une couronne dont elle est munie à son extrémité extérieure. Selon la position axiale de la tige, il est possible, par sa rotation, de corriger l'une ou l'autre des informations affichées, en général le quantième dans la première position tirée, et l'heure dans la seconde.In these timepieces, the order is made by a movement of translation and rotation of the rod, via a crown which it is provided at its outer end. Depending on the axial position of the rod, it is possible, by its rotation, to correct one or other of the displayed information, usually the date in the first drawn position, and the time in the second.

Pour que la tige puisse assurer sa fonction dans des conditions satisfaisantes, son mouvement doit être limité axialement. A cet effet, la tirette est munie d'un plot engagé dans la gorge de la tige.So that the rod can perform its function under satisfactory conditions, its movement must be limited axially. For this purpose, the zipper is provided with a stud engaged in the throat of the rod.

Dans la plupart des mécanismes, la tirette se trouve du côté cadran de la montre. Une vis ou une goupille est accessible du côté fond, pour permettre de repousser la tirette de manière à ce que le plot sorte de la gorge durant l'opération de mise en place et de retrait de la tige. Cette opération est délicate, car elle nécessite deux mouvements simultanés, soit le déplacement de la tirette et le retrait de la tige. In most mechanisms, the pull tab is on the dial side of the shows. A screw or a pin is accessible from the bottom side, to allow push the pull tab so that the stud comes out of the groove for the operation of placing and removing the rod. This operation is delicate, because it requires two simultaneous movements, i.e. moving the zipper and removing the rod.

Un pignon, monté sur la tige de mise à l'heure, est relié cinématiquement, par l'intermédiaire d'un renvoi, au rouage de mise à l'heure ou au rouage de correction du quantième, selon la position de la tige. Le déplacement du pignon contre le premier renvoi est assuré par un mécanisme composé de la tirette et d'une bascule. La tirette coopère avec la bascule par son extrémité opposée à celle portant le plot. La bascule déplace alors le pignon, en appuyant sur l'un ou l'autre des côtés d'une gorge ménagée dans l'épaisseur du pignon. Ce mécanisme est bien connu de l'homme de métier et est, par exemple, décrit dans le livre de théorie de l'horlogerie de Chs-A Reymondin et al, page 40 (Fédération des Ecoles Techniques de Suisse, 1998, ISBN 2-940025).A pinion, mounted on the time-setting rod, is kinematically connected, by through a reference, the time-setting train or the train of correction of the date, depending on the position of the stem. The displacement of the pinion against the first return is ensured by a mechanism composed of the pull tab and a rocker. The puller cooperates with the lever by its end opposite to the one with the stud. The rocker then moves the pinion, by pressing one or the other side of a groove made in the thickness of the pinion. This mechanism is well known to those skilled in the art and is, for example, described in the clock theory book of Chs-A Reymondin et al, page 40 (Federation of Technical Schools of Switzerland, 1998, ISBN 2-940025).

La présente invention propose une solution facilitant le retrait et la mise en place de la tige de mise à l'heure sans avoir à repousser simultanément la tirette.The present invention provides a solution that facilitates removal and installation of the time-setting rod without having to push the zipper simultaneously.

De façon plus précise, l'invention concerne un mécanisme de commande pour pièce d'horlogerie du type comportant un bâti muni de deux faces parallèles définissant un plan de référence, dont l'une est destinée à porter un cadran et l'autre se trouve en regard du fond. Le mécanisme comporte encore, solidaire de ce bâti :

  • une tige de commande munie d'une gorge annulaire ayant une largeur I, un diamètre extérieur D et un diamètre intérieur d, montée mobile en translation dans le bâti selon un premier axe AA' inclus dans ledit plan, et
  • une plaque de maintien montée sur le bâti parallèlement au plan et comportant une pièce de verrouillage coopérant avec la tige par engagement dans la gorge, pour en limiter le déplacement en translation.
More specifically, the invention relates to a control mechanism for a timepiece of the type comprising a frame provided with two parallel faces defining a reference plane, one of which is intended to carry a dial and the other is next to the bottom. The mechanism also includes, integral with this frame:
  • a control rod provided with an annular groove having a width I , an external diameter D and an internal diameter d , mounted movable in translation in the frame along a first axis AA 'included in said plane, and
  • a retaining plate mounted on the frame parallel to the plane and comprising a locking part cooperating with the rod by engagement in the groove, to limit its displacement in translation.

Selon l'invention, la plaque de maintien est montée du côté du fond et elle porte la pièce de verrouillage, montée mobile en rotation autour d'un deuxième axe BB' perpendiculaire au plan de référence. Elle est agencée de manière à ce qu'elle soit susceptible d'occuper une première position, dite de verrouillage, dans laquelle le déplacement en translation de la tige est limité par l'engagement de la pièce de verrouillage dans la gorge et une deuxième position, dite de déverrouillage, dans laquelle ladite pièce n'est plus engagée dans la gorge, permettant ainsi la mise en place de la tige sur le bâti ou son retrait.According to the invention, the retaining plate is mounted on the bottom side and it carries the locking piece, mounted to rotate about a second axis BB 'perpendicular to the reference plane. It is arranged so that that it is likely to occupy a first position, called the locking position, in which the displacement in translation of the rod is limited by the engagement of the locking piece in the groove and a second position, called unlocking, in which said part is no longer engaged in the groove, thus allowing the establishment of the rod on the frame or its removal.

Il est avantageux que la pièce de verrouillage comprenne :

  • une première partie de forme générale cylindrique, engagée dans la plaque de maintien pour permettre sa rotation sur la plaque,
  • une deuxième partie disposée du côté opposé à la tige et agencée pour permettre l'entraínement en rotation de la pièce de verrouillage, et
  • une troisième partie, disposée du côté de la tige, destinée à coopérer avec elle et comportant, à cet effet, deux ailes inscrites dans un cylindre fictif d'axe confondu avec le deuxième axe BB' et de diamètre légèrement inférieur à la largeur I de la gorge, lesdites ailes étant agencées de manière à ce que, dans la position de verrouillage, elles soient inscrites dans le diamètre extérieur D de la gorge et épousent le contour du diamètre intérieur d et, dans la position de déverrouillage, elles épousent le contour du diamètre extérieur D.
It is advantageous for the locking piece to include:
  • a first part of generally cylindrical shape, engaged in the holding plate to allow its rotation on the plate,
  • a second part disposed on the side opposite to the rod and arranged to allow the locking piece to rotate, and
  • a third part, arranged on the side of the rod, intended to cooperate with it and comprising, for this purpose, two wings inscribed in a fictitious cylinder with an axis coincident with the second axis BB 'and of diameter slightly less than the width I of the groove, said wings being arranged so that, in the locked position, they are inscribed in the outside diameter D of the groove and follow the outline of the inside diameter d and, in the unlocked position, they follow the outline of the outside diameter D.

La description qui va suivre fait référence à un mécanisme de commande constitué d'une tige de mise à l'heure pouvant se terminer par un pignon qui lui est solidaire en rotation et en translation et à une plaque de maintien constituée d'une tirette pouvant être mobile en translation.The following description refers to a control mechanism consisting of a time-setting rod which can end with a pinion which is integral in rotation and in translation and with a retaining plate made up a pull tab that can be movable in translation.

Il est très intéressant que la pièce de verrouillage comporte des moyens de positionnement assurant son maintien dans les positions verrouillées et déverrouillées. Ils sont formés par un engagement à friction d'une partie de la pièce de verrouillage sur la plaque de maintien et, dans une réalisation particulièrement avantageuse, par les ailes, qui s'étendent sur les côtés de la gorge au-delà de son fond, et dont leur extrémité libre épouse, en position verrouillée, le contour du diamètre intérieur d, de manière à définir un engagement à cran.It is very interesting that the locking piece includes positioning means ensuring its maintenance in the locked and unlocked positions. They are formed by a friction engagement of part of the locking piece on the retaining plate and, in a particularly advantageous embodiment, by the wings, which extend on the sides of the groove beyond its bottom. , and whose free end follows, in the locked position, the contour of the internal diameter d , so as to define a notched engagement.

L'invention sera mieux comprise à la lecture de la description qui suit, faite en regard du dessin annexé, sur lequel les figures 1a, b, c et 2 a, b, c sont des représentations d'un mécanisme selon l'invention, en position verrouillée et déverrouillée, respectivement en perspective retournée en b, en coupe longitudinale en a et transversale en c selon l'axe de la tige.The invention will be better understood on reading the description which follows, made with reference to the appended drawing, in which FIGS. 1a, b, c and 2 a, b, c are representations of a mechanism according to the invention, in the locked and unlocked position, respectively in perspective turned over at b , in longitudinal section at a and transverse at c along the axis of the rod.

Sur la figure 1a, on a représenté une partie de mouvement de montre, et plus particulièrement en 10 un bâti, par exemple une platine, muni de deux faces parallèles définissant un plan de référence, dont l'une est destinée à porter un cadran et l'autre se trouve en regard du fond. Une tige de mise à l'heure 12, munie d'une gorge annulaire 14 possédant une largeur I, un diamètre extérieur D et un diamètre intérieur d, est montée mobile en translation et en rotation dans le bâti 10, selon un premier axe (AA') inclus dans le plan de référence. L'extrémité de la tige 12 insérée dans le mécanisme de la montre est constituée d'une denture 16, coopérant avec un renvoi de mise à l'heure, qui n'est pas représenté au dessin, et qui pivote sur un plot 18.In FIG. 1a, a part of the watch movement is shown, and more particularly at 10 a frame, for example a plate, provided with two parallel faces defining a reference plane, one of which is intended to carry a dial and the other is next to the bottom. A time-setting rod 12, provided with an annular groove 14 having a width I , an outside diameter D and an inside diameter d , is mounted movable in translation and in rotation in the frame 10, along a first axis ( AA ') included in the reference plane. The end of the rod 12 inserted in the mechanism of the watch consists of a toothing 16, cooperating with a time-setting reference, which is not shown in the drawing, and which pivots on a stud 18.

On se référera maintenant à la figure 1b. Une tirette 20 est montée mobile en translation dans le plan de référence. Elle porte le plot 18 et comporte une pièce de verrouillage 22 coopérant avec la tige 12 par engagement dans sa gorge 14, rendant ainsi la tige 12 et la tirette 20 solidaires en translation. La tirette 20 permet également de positionner la tige 12 dans l'épaisseur du mouvement.We will now refer to FIG. 1b. A pull tab 20 is movably mounted in translation in the reference plane. It carries the stud 18 and has a part locking 22 cooperating with the rod 12 by engagement in its groove 14, thus making the rod 12 and the pull tab 20 integral in translation. Zipper 20 also allows to position the rod 12 in the thickness of the movement.

La tirette 20 est dotée de trous 24 dans lesquels s'engagent des plots fixés sur le bâti, non représentés au dessin, afin d'assurer son guidage lors de ses déplacements en translation.The pull tab 20 is provided with holes 24 in which engage studs fixed on the frame, not shown in the drawing, to ensure its guidance during its translational movements.

La pièce de verrouillage 22 est agencée de manière à pouvoir occuper deux positions, soit l'une dite de verrouillage, dans laquelle la tige 12 et la tirette 20 sont solidaires en translation et l'autre, dite de déverrouillage dans laquelle il est possible de retirer la tige ou de la mettre en place.The locking piece 22 is arranged so that it can occupy two positions, one called locking, in which the rod 12 and the pull tab 20 are secured in translation and the other, called unlocking in which it is possible to remove the rod or put it in place.

La pièce 22 comporte une première partie médiane 26, de forme générale cylindrique, dont une première portion 28 est engagée à friction dans la tirette 20 pour permettre sa rotation selon un deuxième axe BB', qui, fictivement, traverse verticalement le centre de la gorge 14 lorsque la tige est en place et dont une deuxième portion 30, de diamètre supérieur, est engagée dans une noyure 32 formée dans l'épaisseur de la tirette 20 et en appui contre son fond, de façon à positionner axialement la pièce 22.The part 22 comprises a first middle part 26, of general shape cylindrical, a first portion 28 of which is frictionally engaged in the pull tab 20 to allow its rotation along a second axis BB ', which, fictitiously, crosses vertically the center of the groove 14 when the rod is in place and one of which second portion 30, of greater diameter, is engaged in a recess 32 formed in the thickness of the pull tab 20 and pressing against its bottom, so as to position the part 22 axially.

Une deuxième partie 34 de la pièce de verrouillage 22, supérieure, est munie d'une fente 36 la traversant radialement, de manière à pouvoir permettre l'engagement d'un tournevis plat pour faire tourner la pièce 22.A second part 34 of the upper locking piece 22 is provided a slot 36 passing through it radially, so as to be able to allow engaging a flat screwdriver to rotate part 22.

Enfin, la pièce 22 se termine, du côté de la tige de mise à l'heure 10, par une troisième partie 38 qui comporte deux ailes 40, séparées par une ouverture 42 la traversant horizontalement, et disposées symétriquement par rapport à un plan vertical qui, en position déverrouillée, inclut l'axe AA'. Comme le montre la figure 2, les ailes 40 sont destinées à coopérer avec la gorge 14 lorsque la pièce 22 est en position verrouillée. A cet effet, elles sont dimensionnées de manière à ce qu'elles soient inscrites dans un cylindre fictif d'axe confondu avec le deuxième axe BB' et de diamètre légèrement inférieur à la largeur I de la gorge 14.Finally, the part 22 ends, on the side of the time-setting rod 10, by a third part 38 which has two wings 40, separated by an opening 42 passing through it horizontally, and arranged symmetrically with respect to a vertical plane which, in the unlocked position, includes the axis AA '. As shown in Figure 2, the wings 40 are intended to cooperate with the groove 14 when the part 22 is in the locked position. To this end, they are dimensioned so that they are inscribed in a fictitious cylinder with an axis coincident with the second axis BB ′ and with a diameter slightly less than the width I of the groove 14.

La pièce de verrouillage 22 est donc mobile en rotation selon l'axe BB'. Les ailes 40 de la partie 38 de la pièce 22 sont agencées de telle sorte qu'en position verrouillée, visible sur la figure 1c, elles soient inscrites dans le diamètre extérieur D de la gorge 14 et épousent le contour du diamètre intérieur d. Les ailes 40 de la partie 38 occupent ainsi pratiquement tout l'espace compris entre les parois de la gorge 14, de telle sorte que la tige 12 et la tirette 20 sont solidaires dans les mouvements en translation. The locking piece 22 is therefore movable in rotation along the axis BB '. The wings 40 of the part 38 of the part 22 are arranged so that in the locked position, visible in FIG. 1c, they are inscribed in the outside diameter D of the groove 14 and follow the outline of the inside diameter d . The wings 40 of the part 38 thus occupy practically the entire space between the walls of the groove 14, so that the rod 12 and the pull tab 20 are integral in the movements in translation.

Une rotation d'un quart de tour de la pièce de verrouillage 22 permet de passer à la deuxième position déverrouillée, visible sur la figure 2c, dans laquelle les ailes 40 épousent le contour du diamètre extérieur D de la gorge 14. L'axe AA' est alors inclus dans le plan de symétrie des ailes 40. Dans cette position, la gorge 14 est libérée et la tige 10 peut être déplacée en translation indépendamment de la tirette 20, pour permettre sa mise en place ou son retrait.A quarter-turn rotation of the locking piece 22 makes it possible to pass to the second unlocked position, visible in FIG. 2c, in which the wings 40 follow the outline of the outside diameter D of the groove 14. The axis AA 'is then included in the plane of symmetry of the wings 40. In this position, the groove 14 is released and the rod 10 can be moved in translation independently of the pull tab 20, to allow it to be put in place or removed.

On a donc ainsi réalisé une pièce de verrouillage qui permet de passer, sans démonter de pièces, d'une position verrouillée à une position déverrouillée, ces deux positions étant stables. En position verrouillée, la tige de mise à l'heure et la tirette sont parfaitement solidaires en translation, alors qu'en position déverrouillée, la tige peut facilement être retirée ou mise en place.We therefore produced a locking piece which allows passage without disassemble parts, from a locked position to an unlocked position, these two positions being stable. In the locked position, the time setting rod and the pull tab are perfectly secured in translation, while in position unlocked, the rod can easily be removed or put in place.

Dans une variante, les ailes 40, en position verrouillée, s'étendent sur les côtés de la gorge 14, au-delà de son fond, leur extrémité libre épousant le contour du diamètre intérieur d pour assurer le maintien du verrouillage par un cran.In a variant, the wings 40, in the locked position, extend over the sides of the groove 14, beyond its bottom, their free end conforming to the contour of the internal diameter d to ensure that the locking is maintained by a notch.

Pour franchir le cran de verrouillage, la force de rotation appliquée doit vaincre les forces de résistance élastique exercées par la tige 12 et par la tirette 20. Les ailes 40 appuient sur le fond de la gorge 14 et déplacent légèrement la tige 12 et la tirette 20, pour permettre leur passage et la transition vers la position déverrouillée. Dans ce cas, la partie médiane 26 peut être montée libre sur la tirette 20, la position de la pièce de verrouillage 22 étant assurée par le cran.To overcome the locking notch, the applied rotational force must overcome the elastic resistance forces exerted by the rod 12 and by the pull tab 20. The wings 40 press on the bottom of the groove 14 and slightly move the rod 12 and the pull tab 20, to allow their passage and the transition to the position unlocked. In this case, the middle part 26 can be freely mounted on the pull tab 20, the position of the locking piece 22 being ensured by the notch.

La description qui vient d'être faite s'applique à une tige de mise à l'heure, mais il va de soi que l'invention peut très bien s'adapter à n'importe quelle tige de commande et même à un poussoir, susceptible d'être animé d'un mouvement de translation. Dans ce cas, la plaque de maintien de la pièce de verrouillage peut être fixe. Il peut aussi s'agir d'une bascule commandée par le poussoir et faisant partie, par exemple, d'un mécanisme de chronographe.The description which has just been made applies to a time-setting rod, but it It goes without saying that the invention can adapt very well to any rod of control and even a pushbutton, capable of being animated by a movement of translation. In this case, the locking plate for the locking piece can to be fixed. It can also be a rocker controlled by the pusher and making part, for example, of a chronograph mechanism.
