Abstract
Description
La présente invention a pour objet un dispositif de remontage pour pièce d'horlogerie. Dans toute pièce d'horlogerie mécanique, on trouve un système de remontage qui permet de charger l'organe fournissant l'énergie de la montre, généralement le ressort de barillet. On actionne cet organe en se servant d'un tige de remontage, et un train de rouages transmet le mouvement au barillet. Un tel système de remontage porte le nom de remontage manuel et est présent dans toute montre mécanique. Il est composé d'un rochet, d'un barillet, d'une roue de couronne, d'un pignon de remontoir et d'un pignon coulant, d'une tige de remontoir, d'une couronne de remontage et d'un cliquet. Ce système est connu dans l'horlogerie traditionnelle depuis des lustres, et particulièrement des horlogers. Lorsqu'on est en position de remontage, le pignon coulant est plaqué contre le pignon de remontoir, et n'entraíne celui-ci que dans un sens. Si l'on actionne la couronne de remontoir dans ce sens, on entraíne le rouage jusqu'à l'arbre du barillet. Celui-ci est solidaire du rochet qui est retenu par un cliquet, lequel empêche le rochet de revenir en arrière.The present invention has for object a piece winding device watchmaking. In any timepiece mechanical, there is a winding system which allows to charge the organ supplying the energy of the watch, usually the barrel spring. We operates this organ using a rod reassembly, and a train of cogs transmits the barrel movement. Such a winding system is called manual winding and is present in any mechanical watch. It is made up of a ratchet, a barrel, a crown wheel, a pinion winder and a sliding pinion, a winder, winding crown and pawl. This system is known in watchmaking traditional for ages, and particularly watchmakers. When we are in reassembly position, the sliding pinion is plated against the winding pinion, and does not drive it that in a way. If we activate the crown of wind in this direction, we train the cog up to the barrel tree. He is united of the ratchet which is retained by a ratchet, which prevents the ratchet from going back.
Ce système manuel de remontage est parfois doublé d'un système de remontage auxiliaire à masse oscillante. Le système à masse oscillante utilise les mouvements du bras du porteur pour faire balancer une masse oscillante et ainsi actionner le rouage d'un système de remontage. C'est l'inertie propre de la masse qui fournit le couple nécessaire au remontage. Grâce à un système à rouages et à cliquets, il est possible de prévoir une solution pour que la dernière roue du système de remontage tourne toujours dans le même sens quel que soit le sens de rotation de la masse oscillante. Ceci est réalisé avec des roues à cliquets indirects et directs qui ne seront pas décrites en détail, car elles sont parfaitement connues de l'homme du métier.This manual winding system is sometimes doubled an auxiliary mass winding system oscillating. The oscillating mass system uses the movements of the wearer's arm to make swing an oscillating mass and thus activate the cog in a winding system. It's inertia clean of the mass which provides the necessary torque at reassembly. Thanks to a gear system and ratchets, it is possible to provide a solution so that the last wheel of the winding system always turns in the same direction whatever the direction of rotation of the oscillating weight. this is made with indirect ratchet wheels and which will not be described in detail because they are perfectly known to the man of the job.
Le but de la présente invention est de proposer un dispositif de remontage qui ne fasse pas uniquement référence à des pièces oscillantes ou mobiles, mais qui utilise la dilatation de pièces dues à des variations de température.The purpose of the present invention is to provide a winding device that does not only reference to oscillating parts or mobile, but which uses room expansion due to temperature variations.
Le dispositif de remontage pour pièce d'horlogerie selon l'invention, est caractérisé en ce qu'il comprend un moteur constitué par un corps se dilatant et se contractant sous l'effet de ses variations de température, des moyens destinés à transformer les variations du corps en déplacements angulaires étant intercalés entre le moteur et l'arbre du barillet de la pièce d'horlogerie.The piece winding device timepiece according to the invention, is characterized by what it includes a motor made up of a body expanding and contracting under the effect of its temperature variations, means for transform body variations into displacements angular being inserted between the motor and the barrel shaft of the timepiece.
Les moyens destinés à transformer les variations du corps peuvent être agencés de manière à transformer les variations d'allongement et de contraction en un déplacement angulaire de même sens de rotation que l'axe du barillet.Means for transforming variations of the body can be arranged to transform the variations in elongation and contraction in an angular displacement of the same direction of rotation as the axis of the barrel.
Le corps du moteur peut être agencé pour créer une amplification de ces variations d'allongement et de contraction.The motor body can be arranged to create an amplification of these variations in elongation and of contraction.
Le corps du moteur peut être un élément longiligne. Il peut également être constitué d'au moins une lame enroulée en spirale.The motor body can be an element rangy. It can also consist of at least minus a spirally wound blade.
Le corps du moteur peut être constitué par des lames métalliques superposées.The engine body can be made up of superimposed metal blades.
Le corps peut comprendre un élément enroulé en hélice et relié à l'axe d'une vis sans fin entraínant un pignon. The body may include an element wound in propeller and connected to the axis of a driving worm a pinion.
Le corps peut également être constitué par une colonne de mercure longiligne ou en spirale, retenu dans une colonne ou un tube fermé par un piston.The body can also be constituted by a column of long or spiral mercury, retained in a column or a tube closed by a piston.
Le corps pourra être réalisé en un matériau présentant un coefficient de dilatation important et une grande réactivité aux changements de température. Le corps pourra être réalisé en or, ou en platine, ou en un alliage à base de titane, ou encore être constitué par un polymère.The body can be made of a material with a large coefficient of expansion and high reactivity to temperature changes. The body can be made of gold, or platinum, or in a titanium-based alloy, or be consisting of a polymer.
Le dessin représente, à titre d'exemple, trois modes d'exécution d'un dispositif de remontage selon l'invention.The drawing shows, for example, three modes of execution of a winding device according to the invention.
Dans le dessin 2 :
Le dispositif de remontage d'un barillet d'une montre mécanique représenté dans la figure 1, comprend une barre (10) présentant un coefficient de dilatation thermique relativement élevé. La barre (10) sera réalisée dans un matériau présentant également un réactivité importante à tout changement de température. Elle pourra par exemple être réalisée en or, en platine, ou dans un alliage de titane. Elle peut également être réalisée dans un matériau non métallique, par exemple un polymère. La barre (10) comprend une extrémité fixe, l'autre extrémité étant reliée par l'intermédiaire d'un pivot (11) à une planche (12) solidaire d'une roue dentée (13). La roue dentée (13) est le premier organe d'une liaison cinématique transformant les variations de longueurs de la barre (10) en déplacements angulaires intermittents, de même sens, d'une roue à rochet (14).The device for winding a barrel of a mechanical watch shown in figure 1, includes a bar (10) having a coefficient of relatively high thermal expansion. The bar (10) will be made of a material that also has a significant reactivity to any change in temperature. It could for example be carried out in gold, platinum, or a titanium alloy. She can also be made of a non-material metallic, for example a polymer. The bar (10) includes a fixed end, the other end being connected via a pivot (11) to a board (12) integral with a toothed wheel (13). Wheel toothed (13) is the first organ of a connection kinematics transforming length variations of the bar (10) in angular displacements intermittent, in the same direction, of a ratchet wheel (14).
La liaison cinématique entre la roue dentée (13) et la roue à rochet (14), est parfaitement connue de l'homme du métier, et est utilisée dans les mécanismes de remontage automatique comprenant une masse oscillante. Elle sera par conséquent décrite très sommairement. La roue dentée (13) attaque un renvoi (15) en prise avec 2 roues à cliquet (16 et 17), un renvoi (18) et une couronne dentée (19) engrainant avec la roue à rochet (14) retenue par un cliquet (20) coopérant avec un sautoir (21). La liaison cinématique comprenant les éléments (15 à 21) permet de transformer les variations de longueur de la barre (10) en variations angulaires de la roue à rochet (14), étant entendu que grâce aux deux roues à cliquet (16 et 17), la rotation de la couronne dentée (19) se fait dans le même sens quel que soit le sens de rotation de la roue dentée (13).The kinematic connection between the toothed wheel (13) and the ratchet wheel (14), is perfectly known from skilled in the art, and is used in mechanisms automatic winding comprising a mass oscillating. It will therefore be described very summarily. The toothed wheel (13) attacks a gear (15) engaged with 2 ratchet wheels (16 and 17), one return (18) and a toothed crown (19) causing with the ratchet wheel (14) retained by a pawl (20) cooperating with a jumper (21). The kinematic link comprising the elements (15 to 21) allows transform bar length variations (10) in angular variations of the ratchet wheel (14), it being understood that thanks to the two ratchet wheels (16 and 17), the rotation of the ring gear (19) is done in the same direction whatever the meaning of rotation of the toothed wheel (13).
Les variations de longueur de la barre (10) n'arment toutefois le ressort du barillet (14) qu'au moment où le cliquet (20) saute une dent de la couronne dentée (19). Pour permettre un réglage adéquat du dispositif en fonction de ces différents paramètres, la planche (12) présente un certain nombre d'ouvertures destinées à recevoir le pivot (11).Bar length variations (10) however, only charge the spring of the barrel (14) when the pawl (20) jumps a tooth from the toothed crown (19). To allow adjustment adequate device according to these different parameters, the board (12) has a certain number openings intended to receive the pivot (11).
Dans le mode d'exécution de la figure 2 , qui représente un mécanisme de remontage basé sur le même principe que le dispositif de la figure 1, la barre (10) est remplacée par des lames métalliques (23) superposées et enroulées en spirale, une des extrémités de la spirale comprend une partie fixe (24), l'autre extrémité (11) supportant la planche (12)sur laquelle est fixée la roue dentée (13). Comme représenté dans le dessin, la planche 12 comprend plusieurs ouvertures (22) permettant de recevoir la roue dentée (13).In the embodiment of Figure 2, which represents a winding mechanism based on the same principle that the device of Figure 1, the bar (10) is replaced by metal blades (23) superimposed and wound in a spiral, one of the ends of the spiral includes a fixed part (24), the other end (11) supporting the board (12) on which the toothed wheel (13) is fixed. As shown in the drawing, plate 12 includes several openings (22) for receiving the toothed wheel (13).
On remarque immédiatement que dans le mode d'exécution de la figure 2, l'allongement ou la contraction de la spirale est beaucoup plus important que ne peut l'être celui de la barre (10) du mode d'exécution de la figure 1. D'autre part, la spirale présentant une certaine élasticité, l'allongement de celle-ci se transforme en son centre en une rotation de la roue dentée (13) qui peut être directement utilisée pour attaquer par exemple un mécanisme semblable à celui de la figure 1.We immediately notice that in the mode of execution of FIG. 2, the elongation or the spiral contraction is much more important that can not be that of the mode bar (10) of execution of figure 1. On the other hand, the spiral with a certain elasticity, the elongation of this turns in its center in a rotation the toothed wheel (13) which can be directly used to attack for example a mechanism similar to that in Figure 1.
Les mécanismes représentés dans les modes d'exécution des figures 1 et 2 qui viennent d'être décrits, présentent une barre (10) respectivement une spirale comprenant plusieurs lames métalliques (23) qui seront réalisées dans un matériau présentant une réactivité importante à tout changement de température, de même qu'un coefficient de dilatation aussi important que possible. La spirale formée des lames (23) pourra ainsi être réalisée comme la barre du mode d'exécution précédent, en or, en platine, dans un alliage de titane, ou dans une matière non métallique, par exemple un polymère.The mechanisms represented in the modes of execution of FIGS. 1 and 2 which have just been described, have a bar (10) respectively a spiral comprising several metal blades (23) which will be made of a material with a significant reactivity to any change in temperature, as well as a coefficient of expansion as important as possible. The spiral formed of blades (23) can thus be produced like the bar of the previous embodiment, in gold, platinum, in a titanium alloy, or in a material not metallic, for example a polymer.
Dans le mode d'exécution de la figure 3, la barre d'allongement (10) du mode d'exécution de la figure 1 est remplacée par une lame de forme hélicoïdale (25) couplée avec une vis sans fin (26). La vis sans fin (26) est montée sur un axe (27) tournant librement dans des butées (28 et 29). La vis sans fin (26) attaque un pignon (30) sur l'axe duquel est montée la roue dentée (13) représentant la première pièce de la liaison cinématique représentée dans la figure 1.In the embodiment of Figure 3, the bar extension (10) of the embodiment of Figure 1 is replaced by a helical blade (25) coupled with a worm screw (26). The worm (26) is mounted on a freely rotating axis (27) in stops (28 and 29). The worm (26) attacks a pinion (30) on the axis of which is mounted the toothed wheel (13) representing the first part of the kinematic link shown in Figure 1.
Avec la mode d'exécution de la figure 3, l'homme du métier remarque que la lame hélicoïdale (25) permet, si l'on prévoit un grand nombre de tours, d'obtenir un effet de démultiplication important lors de sa dilatation due à un changement de température.With the embodiment of Figure 3, the man of the profession notices that the helical blade (25) allows, if a large number of turns is planned, achieve a significant reduction effect during of its expansion due to a change in temperature.
Comme dans les modes d'exécution précédents, le matériau utilisé pour réaliser la lame hélicoïdale (25) sera choisi de manière à présenter une réactivité ainsi qu'un coefficient de dilatation importants à tout changement de température. Elle pourra par conséquent être réalisée dans un matériau présentant ces caractéristiques.As in the previous embodiments, the material used to make the helical blade (25) will be chosen so as to present a reactivity as well as a large coefficient of expansion at any change in temperature. By therefore be made of a material having these characteristics.
L'invention n'est évidemment pas limitée aux trois modes d'exécution représentés, aux dessins, et décrits ci-dessus. En particulier, les variations de dimension du corps (10, 23 ou 25) susceptibles de se dilater pourraient être amplifiés par des moyens appropriés en fonction des caractéristiques du barillet de la pièce d'horlogerie. En particulier, on peut concevoir avantageusement une barre de dilatation se présentant sous forme d'un colonne ou d'une spirale de mercure contenue dans un tube. L'une des extrémités du tube sera fermée, l'autre présentera un piston - non représenté - permettant de valoriser son déplacement dû à l'allongement ou à la contraction de la colonne de mercure sous l'effet des variations de température. Le mercure présentant un bon coefficient de dilatation relativement aux changements de température, cette solution peut présenter des avantages, étant entendu que la colonne de mercure peut être contenue dans un tube qui se présente sous toute forme adéquate, par exemple sous la forme d'une spirale ou d'un hélicoïde. Ce mode d'exécution étant particulièrement simple du point de vue de son principe, il ne sera pas décrit en détail.The invention is obviously not limited to three embodiments shown, in the drawings, and described above. In particular, variations in dimension of the body (10, 23 or 25) likely to be dilate could be amplified by means appropriate according to the characteristics of the barrel of the timepiece. In particular, we can advantageously design an expansion bar in the form of a column or a spiral of mercury in a tube. One end of the tube will be closed, the other will have a piston - not shown - to enhance your displacement due to lengthening or contraction of the column of mercury under the effect of variations in temperature. Mercury having a good coefficient dilation relative to changes in temperature, this solution may have advantages, it being understood that the mercury column can be contained in a tube which is presented under any suitable form, for example in the form of a spiral or helical. This mode of execution being particularly simple from the point of view of its principle, it will not be described in detail.
