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 mechanism for transmitting axial and rotary movements between two offset axes finding a particular application in a mechanism for setting the time and winding of a timepiece and more particularly to such a mechanism comprising a crown of winding operating a winding and setting time.

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 whose winding stem and setting time is in two parts of axes located in parallel planes but offset with respect to each other. Such mechanisms of winding and setting time rod stem two offset parts are particularly useful for complicated movements, including modular, because in such movements the winding stem is offset with respect to the median plane of the movement. which is a disadvantage from the practical and especially aesthetic point of view.

On connaît 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.Such a device for reassembling and setting the time of the document is known. DE 197 25 884 which discloses a winding and setting rod in two parts of parallel axes and offset kinematically connected firstly in rotation by a first kinematic link and secondly in translation by a second kinematic link. The major disadvantage of the mechanism described in this document lies in the fact that the first kinematic connection introduces a reversal of the direction of rotation between the first and the second part of the winding and setting rod. This is particularly unpleasant for the user when setting the time because it is in the opposite direction 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 enable the realization of a mechanism for transmitting axial and rotary movements between two axes, in particular a winding mechanism and time setting comprising a winding rod in two parts of axes located in parallel planes kinematically connected 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 mechanism for transmitting axial and rotary movements between two axes located in parallel planes and in particular a winding and setting mechanism for a timepiece comprising a winding rod in two. parts of axes lying in parallel planes, these two parts of the winding rod being connected kinematically for both rotations and translations and 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.

  • La figure 1 est une coupe axiale du mécanisme
  • La figure 2 est une vue de dessus du mécanisme.
  • La figure 3 est une vue en bout du chariot mobile reliant les première et seconde parties de la tige de remontoir.
The accompanying drawing illustrates schematically and by way of example an embodiment of the mechanism for transmitting axial and rotary movements according to the invention applied to a winding mechanism and setting time of a timepiece.
  • The figure 1 is an axial section of the mechanism
  • The figure 2 is a top view of the mechanism.
  • The figure 3 is an end view of the movable 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.The figure 1 is a partial section of a timepiece provided with the winding and setting mechanism according to the invention.

La pièce d'horlogerie comporte une boîte 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 having a bottom 1, a caseband 2 and an ice 3 inside which is mounted a movement 4 optionally equipped with an additional mechanism 5 located between the movement 4 and the 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 entraînant 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 can be seen, the first part 8 of the winding stem, part of the movement 4, is located much lower than the median plane of this timepiece because of the extra thickness due to the chronograph module 5. The first part 8 of the winding stem has near its end located in the movement 4 a square 10 to go up by a conventional wheel barrel movement when this part 8 of the winding stem is in the winding position illustrated in the figure 1 . This square 10 slides in a conventional manner in a mobile actuating a kinematic link rotating the switch of the movement for its setting time when this first portion 8 of the winding stem is in the drawn position of time setting in dots at the 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 of two plates, a front plate 11 and a rear plate 12 fixed together and in parallel planes by means of rivets 13. distance between these plates 11 and 12 is determined by spacers 14 constituted by the median portion 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 winding stem and located between the two plates 11, 12 is a first pinion 15. This first pinion 15 is engaged with a return 16 rotated crazy between the plates 11 and 12. This pinion 15 comprises a hub 15a so that the thickness of the pinion 15 and its hub 15a occupies the entire space between the two plates 11 and 12 of the moving assembly. The reference 16 is engaged with a second pinion 17, also located between the plates 11 and 12 of the moving element, secured to the inner end of the second portion 18 of the winding stem which is housed and pivoted in a light made in the plate 11 of the moving element 11, 12, opening into 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 tightly crosses the caseband 2 and ends with a winding crown 19.

L'équipage mobile 11, 12 est disposé en partie au moins Jans 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 movable element 11, 12 is arranged in part at least in a housing 20 formed radially in the middle case 2. In variants this mobile unit could be partially or completely housed in the movement 4 or its additional mechanism 5. The plate 11 of this moving element is caught without play 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 element 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 following that the user places the crown 19 in its depressed position, illustrated in the figure 1 in solid lines, or in its retracted position, illustrated in phantom lines at the figure 1 , the first part 8 of this winding stem, parallel but offset, also undergoes axial movements moving it to the winding position, respectively setting the time of 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 prints a rotation to the crown 19 and therefore to the second portion 18 of the winding stem, this rotation is transmitted by the second pinion 17, the return 16 and the first pinion 15 to the first portion 8 of the stem winding. Because of the presence of the return 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 boîte 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 setting mechanism makes it possible to arrange the winding crown 19 in the center plane of the watch case even though the movement 4 is offset with respect to this median plane. In addition, this mechanism causes during the rotation of the winding crown 19 a rotation in the same direction of the first portion 8 of the winding stem allowing a time setting of the movement 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 setting mechanism therefore comprises a first part 8 of winding rod cooperating with the movement 4, pivoted in the movable assembly 11, 12, but axially integral with this assembly and a second part 18 winding rod pivoted in the movable assembly 11, 12 but axially secured thereto. Thus, the two parts 8, 18 of the winding stem are axially integral with each other through the movable assembly 11, 12. In addition, these two parts 8, 18 of the winding stem are connected by the first 15 and second gears 17 and the reference 16, the first part 8 of this rod therefore follows the rotational movements of the second portion 18 of this rod. Thus the two parts 8, 18 of the winding stem are kinematically connected for their translational and rotational movements and their rotation is in the same direction. The kinematic translation link is formed by the movable assembly 11, 12; the first pinion 15 and its hub 15a and the second pinion 17 and its hub and the end of large diameter of the second portion 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 timepieces having a movement alone or with one or more additional mechanisms for reassembly and setting time. , either for actuating a calendar 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 return 16 causing the reversal of the rotational movement so that the two rod parts rotate in the same direction can be replaced by a gear train comprising an odd number of wheels, this may be necessary if the distance separating the two planes in which are the two parts of the stem 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 movable assembly 11, 12 could have come from a single workpiece made by machining a single block.

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 boîte de montre par le fond de la boîte, le fond 1 ayant été retiré, sans enlever la tige du remontoir 18.An advantage of the described mechanism lies in the fact that the rod portion 18 being placed and pivoted in a light of the moving assembly, the movement and its additional mechanisms can be removed from the watch case by the bottom of the box, the bottom 1 having been removed, without removing the winding stem 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 the two axes are parallel to each other. In a variant these axes may be located in parallel planes but be angularly offset between them. It is sufficient that the gear train connecting the two parts 8, 18 axes comprises conical 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 described mechanism can also be used in non-horological applications wherever it is necessary to transmit between two axes, located in parallel planes, axial and rotary movements.
