Description

La présente invention se rapporte à un mécanisme de transmission de mouvements axiaux et rotatifs entre deux axes décalés trouvant une application particulière dans un mécanisme de mise à l'heure et de remontage d'une pièce d'horlogerie et plus particulièrement à un tel mécanisme comportant une couronne de remontoir actionnant une tige de remontoir et de mise à l'heure.The present invention relates to a transmission mechanism axial and rotary movements between two offset axes finding a particular application in a time-setting and winding mechanism a timepiece and more particularly to such a mechanism comprising a winding crown actuating a winding and time setting rod.

Plus particulièrement, la présente invention a trait à un tel mécanisme dont la tige de remontoir et de mise à l'heure est en deux parties d'axes situés dans des plans parallèles mais décalées l'une par rapport à l'autre. De tels mécanismes de remontage et de mise à l'heure à tige en deux pièces décalées sont particulièrement utiles pour des mouvements à complications, notamment modulaires, car dans de tels mouvements la tige de remontoir se trouve décalée par rapport au plan médian du mouvement ce qui est un inconvénient du point de vue pratique et surtout esthétique.More particularly, the present invention relates to such a mechanism, the winding and time-setting stem is in two parts of axes located in planes parallel but offset from each other. Such mechanisms winding and time setting with stem in two offset pieces are particularly useful for movements with complications, in particular modular, because in such movements the winding stem is offset with respect to the median plane of the movement which is a disadvantage of the point of practical and above all aesthetic view.

On connaít un tel dispositif de remontage et de mise à l'heure du document DE 197 25 884 qui divulgue une tige de remontoir et de mise à l'heure en deux parties d'axes parallèles et décalées reliées cinématiquement d'une part en rotation par une première liaison cinématique et d'autre part en translation par une seconde liaison cinématique.L'inconvénient majeur du mécanisme décrit dans ce document réside dans le fait que la première liaison cinématique introduit une inversion du sens de rotation entre la première et la seconde partie de la tige de remontage et de mise à l'heure. Cela est particulièrement désagréable pour l'usager lors de la mise à l'heure car elle se fait en sens inverse de ce qui est habituel.We know such a device for winding up and setting the time of the document DE 197 25 884 which discloses a winding and time setting rod in two parts of parallel and offset axes kinematically connected on the one hand in rotation by a first kinematic link and on the other hand in translation by a second kinematic link. The major drawback of the mechanism described in this document lies in the fact that the first kinematic link introduces a reversing the direction of rotation between the first and second part of the rod winding and setting the time. This is particularly unpleasant for the user when setting the time because it is done in reverse of what is usual.

La présente invention a pour but de permettre la réalisation d'un mécanisme de transmission de mouvement axiaux et rotatifs entre deux axes, notamment d'un mécanisme de remontage et de mise à l'heure comportant une tige de remontage en deux parties d'axes situés dans des plans parallèles reliées cinématiquement en rotation et en translation mais qui évite une inversion du sens de rotation des deux parties de la tige de remontage.The present invention aims to allow the realization of a mechanism for transmitting axial and rotary movements between two axes, in particular a winding and time-setting mechanism comprising a winding rod in two parts of axes located in connected parallel planes kinematically in rotation and in translation but which avoids a reversal of the direction of rotation of the two parts of the winding rod.

La présente invention a pour objet un mécanisme de transmission de mouvements axiaux et rotatifs entre deux axes situés dans des plans parallèles et notamment un mécanisme de remontage et de mise à l'heure d'une pièce d'horlogerie comportant une tige de remontage en deux parties d'axes situés dans des plans parallèles, ces deux parties de la tige de remontage étant reliées cinématiquement tant pour des rotations que pour des translations et qui se distingue par les caractéristiques énumérées dans la revendication 1.The subject of the present invention is a transmission mechanism for axial and rotary movements between two axes located in parallel planes and in particular a mechanism for winding and setting the time of a piece timepiece comprising a winding rod in two parts of axes located in parallel planes, these two parts of the winding rod being connected kinematically both for rotations and for translations and which is distinguished by the features listed in claim 1.

Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution du mécanisme de transmission de mouvements axiaux et rotatifs selon l'invention appliqué à un mécanisme de remontage et de mise à l'heure d'une pièce d'horlogerie.The attached drawing illustrates schematically and by way of example a shape of the mechanism for transmitting axial and rotary movements according to the invention applied to a winding and time-setting mechanism of a timepiece.

La figure 1 est une coupe axiale du mécanismeFigure 1 is an axial section of the mechanism

La figure 2 est une vue de dessus du mécanisme.Figure 2 is a top view of the mechanism.

La figure 3 est une vue en bout du chariot mobile reliant les première et seconde parties de la tige de remontoir.FIG. 3 is an end view of the mobile carriage connecting the first and second parts of the winding stem.

La figure 1 est une coupe partielle d'une pièce d'horlogerie munie du mécanisme de remontage et de mise à l'heure selon l'invention.Figure 1 is a partial section of a timepiece provided with the winding and time-setting mechanism according to the invention.

La pièce d'horlogerie comporte une boíte comportant un fond 1, une carrure lunette 2 et une glace 3 à l'intérieur de laquelle est monté un mouvement 4 éventuellement équipé d'un mécanisme additionnel 5 situé entre le mouvement 4 et le cadran 7.The timepiece comprises a box comprising a bottom 1, a middle part telescope 2 and a crystal 3 inside which a movement 4 is mounted possibly equipped with an additional mechanism 5 located between movement 4 and dial 7.

Comme on le voit, la première partie 8 de la tige de remontoir, faisant partie du mouvement 4, est située bien plus bas que le plan médian de cette pièce d'horlogerie du fait de la surépaisseur due au module chronographe 5. La première partie 8 de la tige de remontoir comporte à proximité de son extrémité située dans le mouvement 4 un carré 10 permettant de remonter par un rouage conventionnel le barillet du mouvement lorsque cette partie 8 de la tige de remontoir est en position de remontage illustrée à la figure 1. Ce carré 10 coulisse de façon conventionnelle dans un mobile actionnant une liaison cinématique entraínant en rotation l'aiguillage du mouvement pour sa mise à l'heure lorsque cette première partie 8 de la tige de remontoir est en position tirée de mise à l'heure illustrée en pointillés à la figure 1.As we can see, the first part 8 of the winding stem, being part of movement 4, is located much lower than the median plane of this piece because of the extra thickness due to the chronograph module 5. The first part 8 of the winding stem comprises near its end located in movement 4 a square 10 allowing to go up by a gear train conventional the barrel of the movement when this part 8 of the rod winder is in the winding position illustrated in Figure 1. This square 10 slides conventionally in a mobile actuating a kinematic link rotating the movement switch to set the time when this first part 8 of the winding stem is in the pulled-out position. the time shown in dotted lines in Figure 1.

L'extrémité libre de cette première partie 8 de la tige de remontoir est pivotée dans un ensemble mobile formé de deux plaques, une plaque avant 11 et une plaque arrière 12 fixées ensemble et dans des plans parallèles à l'aide de rivets 13. La distance entre ces plaques 11 et 12 est déterminée par des entretoises 14 constituée par la partie médiane des rivets 13 entre les deux plaques 11, 12.The free end of this first part 8 of the winding stem is pivoted in a mobile assembly formed by two plates, a front plate 11 and a back plate 12 fixed together and in parallel planes using rivets 13. The distance between these plates 11 and 12 is determined by spacers 14 formed by the middle part of the rivets 13 between the two plates 11, 12.

Monté rigidement sur l'extrémité de la première partie 8 de la tige de remontoir et situé entre les deux plaques 11, 12 se trouve un premier pignon 15. Ce premier pignon 15 est en prise avec un renvoi 16 pivoté fou entre les plaques 11 et 12. Ce pignon 15 comporte un moyeu 15a de sorte que l'épaisseur du pignon 15 et de son moyeu 15a occupe tout l'espace compris entre les deux plaques 11 et 12 de l'équipage mobile. Le renvoi 16 est en prise avec un second pignon 17, également situé entre les plaques 11 et 12 de l'équipage mobile, solidaire de l'extrémité interne de la seconde partie 18 de la tige de remontoir qui est logée et pivotée dans une lumière pratiquée dans la plaque 11 de l'équipage mobile 11, 12, lumière débouchant sur la tranche supérieure de cette plaque 11.Rigidly mounted on the end of the first part 8 of the rod winder and located between the two plates 11, 12 is a first pinion 15. This first pinion 15 is engaged with an idler 16 pivoted idly between the plates 11 and 12. This pinion 15 has a hub 15a so that the thickness of the pinion 15 and its hub 15a occupies all the space between the two plates 11 and 12 of the moving assembly. Reference 16 is engaged with a second pinion 17, also located between plates 11 and 12 of the movable assembly, secured to the internal end of the second part 18 of the winding stem which is housed and pivoted in a light made in the plate 11 of the crew mobile 11, 12, light opening onto the upper edge of this plate 11.

L'extrémité externe de la seconde partie 18 de la tige de remontoir traverse de façon étanche la carrure lunette 2 et se termine par une couronne de remontoir 19.The outer end of the second part 18 of the winding stem crosses watertight the middle bezel 2 and ends with a winding crown 19.

L'équipage mobile 11, 12 est disposé en partie au moins dans un logement 20 formé radialement dans la carrure lunette 2. Dans des variantes cet équipage mobile pourrait être partiellement ou totalement logée dans le mouvement 4 ou son mécanisme additionnel 5. La plaque 11 de cet équipage mobile est prise sans jeu entre le moyeu du second pignon 17 et une partie de grand diamètre de la seconde partie 18 de la tige de remontoir de sorte que l'équipage mobile 11, 12 suit les mouvements axiaux de cette première partie 18 de la tige de remontoir et les communique à la première partie 8 de la tige de remontoir.The moving element 11, 12 is disposed at least in part in a housing 20 formed radially in the middle of the bezel 2. In variants this crew mobile could be partially or totally housed in movement 4 or its additional mechanism 5. The plate 11 of this mobile assembly is taken without clearance between the hub of the second pinion 17 and a large diameter part of the second part 18 of the winding stem so that the moving assembly 11, 12 follows the axial movements of this first part 18 of the winding stem and communicates them to the first part 8 of the winding stem.

Ainsi suivant que l'usager place la couronne 19 dans sa position enfoncée, illustrée à la figure 1 en traits pleins, ou dans sa position rétractée, illustrée en traits mixtes à la figure 1, la première partie 8 de cette tige de remontoir, parallèle mais décalée, subit également des mouvements axiaux la déplaçant en position de remontage, respectivement de mise à l'heure du mouvement 4.Thus depending on whether the user places the crown 19 in its depressed position, illustrated in FIG. 1 in solid lines, or in its retracted position, illustrated in mixed lines in Figure 1, the first part 8 of this winding stem, parallel but offset, also undergoes axial movements moving it in position winding, respectively setting the time of the movement 4.

Lorsque l'usager imprime une rotation à la couronne 19 et donc à la seconde partie 18 de la tige de remontoir, cette rotation est transmise par le second pignon 17, le renvoi 16 et le premier pignon 15 à la première partie 8 de la tige de remontoir. Du fait de la présence du renvoi les première 8 et seconde 18 parties de la tige de remontoir tournent dans le même sens.When the user rotates the crown 19 and therefore the second part 18 of the winding stem, this rotation is transmitted by the second pinion 17, the reference 16 and the first pinion 15 to the first part 8 of the winding stem. Due to the presence of the referral the first 8 and second 18 parts of the winding stem rotate in the same direction.

Ce mécanisme de remontage et de mise à l'heure permet de disposer la couronne de remontoir 19 dans le plan médian de la boíte de montre bien que le mouvement 4 soit décalé par rapport à ce plan médian. De plus, ce mécanisme provoque lors de la rotation de la couronne de remontoir 19 une rotation dans le même sens de la première partie 8 de la tige de remontoir permettant une mise à l'heure du mouvement de façon traditionnelle et aisée pour l'usager.This winding and time-setting mechanism allows the winding crown 19 in the median plane of the watch case although the movement 4 is offset from this median plane. In addition, this mechanism causes the winding crown 19 to rotate in the same direction of the first part 8 of the winding stem allowing a setting movement time in a traditional and easy way for the user.

Ce mécanisme de remontage et de mise à l'heure comporte donc une première partie 8 de tige de remontage coopérant avec le mouvement 4, pivotée dans l'ensemble mobile 11, 12, mais axialement solidaire de cet ensemble ainsi qu'une seconde partie 18 de tige de remontage pivotée dans l'ensemble mobile 11, 12 mais axialement solidaire de celui-ci. Ainsi, les deux parties 8, 18 de la tige de remontoir sont axialement solidaires l'une de l'autre par l'intermédiaire de l'ensemble mobile 11, 12. De plus, ces deux parties 8, 18 de la tige de remontoir sont reliées par les premier 15 et second pignons 17 ainsi que le renvoi 16, la première partie 8 de cette tige suit donc les mouvements de rotation de la seconde partie 18 de cette tige. Ainsi les deux parties 8, 18 de la tige de remontoir sont reliées cinématiquement pour leurs mouvements de translation et de rotation et leur rotation s'effectue dans le même sens. La liaison cinématique de translation est réalisée par l'ensemble mobile 11, 12; le premier pignon 15 et son moyeu 15a et par le second pignon 17 et son moyeu et l'extrémité de grand diamètre de la seconde partie de la tige 18.This winding and time-setting mechanism therefore includes a first part 8 of winding rod cooperating with movement 4, pivoted in the movable assembly 11, 12, but axially integral with this assembly as well that a second part 18 of the winding rod pivoted in the mobile assembly 11, 12 but axially integral with it. Thus, the two parts 8, 18 of the rod winders are axially integral with one another by means of the movable assembly 11, 12. In addition, these two parts 8, 18 of the winding stem are connected by the first 15 and second pinions 17 as well as the reference 16, the first part 8 of this rod therefore follows the rotational movements of the second part 18 of this rod. Thus the two parts 8, 18 of the winding stem are kinematically linked for their translational and rotational movements and they rotate in the same direction. The kinematic translation link is produced by the mobile assembly 11, 12; the first pinion 15 and its hub 15a and by the second pinion 17 and its hub and the large diameter end of the second part of the rod 18.

Un tel mécanisme de transmission de mouvements axiaux et rotatifs entre deux axes situés dans deux plans parallèles peut-être appliqué dans des pièces d'horlogeries ayant un mouvement seul ou comportant un ou des mécanismes additionnels soit pour le remontage et la mise à l'heure, soit pour l'actionnement d'une fonction de quantième ou de réveil etc.Such a mechanism for transmitting axial and rotary movements between two axes located in two parallel planes can be applied in parts timepieces having a single movement or comprising one or more mechanisms either for winding and setting the time, or for actuation a date or alarm function, etc.

Dans une variante le renvoi16 provoquant l'inversion du mouvement de rotation pour que les deux parties de tige tournent dans le même sens peut-être remplacé par un train d'engrenage comportant un nombre impair de rouages, ceci peut-être nécessaire si la distance séparant les deux plans dans lesquels se trouvent les deux parties de la tige est grande.In a variant, the return16 causing the reversal of the movement of rotation so that the two rod parts rotate in the same direction maybe replaced by a gear train with an odd number of cogs, this may be necessary if the distance between the two planes in which find the two parts of the rod is large.

Dans une variante l'ensemble mobile 11,12 pourrait être venu d'une seule pièce de fabrication réalisé par usinage d'un seul bloc.In a variant, the mobile assembly 11.12 could have come from a single workpiece produced by machining in one piece.

Un avantage du mécanisme décrit réside encore dans le fait que la partie de tige 18 étant placée et pivotée dans une lumière de l'ensemble mobile, le mouvement et ses mécanismes additionnels peuvent être sortis de la boíte de montre par le fond de la boíte, le fond 1 ayant été retiré, sans enlever la tige du remontoir 18.An advantage of the mechanism described also lies in the fact that the part rod 18 being placed and pivoted in a lumen of the movable assembly, the movement and its additional mechanisms can be taken out of the box shows by the bottom of the box, the bottom 1 having been removed, without removing the rod from the wind 18.

Dans la forme d'exécution illustrée du mécanisme de transmission les deux axes sont parallèles entre eux. Dans une variante ces axes peuvent être situés dans des plans parallèles mais être angulairement décalés entre eux. Il suffit en effet que le train d'engrenage reliant les deux parties 8,18 d'axes comporte des engrenages coniques. In the illustrated embodiment of the transmission mechanism both axes are parallel to each other. In a variant, these axes can be located in parallel planes but be angularly offset between them. It is enough effect that the gear train connecting the two parts 8,18 of axes has bevel gears.

Le mécanisme décrit peut également être utilisé dans des applications non horlogère partout où il s'agit de transmettre entre deux axes, situés dans des plans parallèles, des mouvements axiaux et rotatifs.The mechanism described can also be used in non-applications watchmaking wherever it involves transmitting between two axes, located in planes parallel, axial and rotary movements.
