Description

DISPOSITIF INDICATEUR DE RÉSERVE DE MARCHE POWER RESERVE INDICATOR DEVICE
La présente invention est relative à une pièce d'horlogerie, plus particulièrement au mécanisme permettant de mesurer et d'afficher l'énergie de fonctionnement emmagasinée dans une montre.The present invention relates to a timepiece, more particularly to the mechanism for measuring and displaying the operating energy stored in a watch.
Les montres mécaniques à remontage manuel disposent obligatoirement d'un système de remontage, appelé remontoir. C'est à travers ce dispositif que se transmet manuellement l'énergie au barillet, accumulateur d'énergie de la montre. Le remontoir est également utilisé pour d'autres fonctions telles que la remise à l'heure ou le changement de date.Mechanical watches with manual winding must have a winding system, called a winder. It is through this device that energy is manually transmitted to the barrel, the watch's energy accumulator. The winder is also used for other functions such as resetting the time or changing the date.
En tournant la couronne, le pignon coulant étant engagé dans le pignon de remontoir, on met en rotation la roue de couronne. Cette dernière faisant tourner le rochet, étant lui-même fixé sur l'arbre de barillet, on charge ainsi le barillet dans une montre traditionnelle. Le calcul du nombre de tours d'armage/désarmage est parfaitement maîtrisé.By turning the crown, the sliding pinion being engaged in the winding pinion, the crown wheel is rotated. The latter rotating the ratchet, being itself fixed on the barrel shaft, the barrel is thus loaded in a traditional watch. The calculation of the number of arming / disarming turns is perfectly mastered.
Afin d'augmenter l'autonomie d'une montre, il est connu d'utiliser des mouvements avec double barillets, tel qu'illustré dans le brevet CH 610465, en particulier la figure 2. Le principe du remontage susmentionné est applicable aux montres de ce type.In order to increase the autonomy of a watch, it is known to use movements with double barrels, as illustrated in patent CH 610465, in particular FIG. 2. The principle of the winding mentioned above is applicable to watches of this guy.
Il s'est avéré utile d'indiquer l'autonomie de telles montres, que ce soit pour les montres à simple ou à double barillets. Cette indication est appelée "réserve de marche".It has proved useful to indicate the autonomy of such watches, whether for single or double barrel watches. This indication is called "power reserve".
Un tel dispositif est décrit dans le document EP 0 568 499. Ce dispositif est compliqué et nécessite de nombreux composants et ne s'applique qu'à une montre à simple barillet.Such a device is described in document EP 0 568 499. This device is complicated and requires many components and only applies to a watch with a single barrel.
Le but de la présente invention est de proposer un dispositif d'indication de réserve de marche pour montres à double barillets, aussi bien celles à remontage manuel, que celles à remontage automatique. Ce but est atteint par un dispositif de réserve de marche, comprenant deux barillets, l'un dit d'armage et l'autre dit de désarmage, une roue-étoile solidaire d'un moyen d'affichage, caractérisé en ce que le barillet d'armage comprend une goupille d'armage actionnant un levier d'armage entraînant en rotation positive la roue-étoile, le barillet de désarmage comprend une goupille de désarmage actionnant un levier de désarmage entraînant en rotation négative la roue-étoile, cette dernière étant maintenue dans sa position par un sautoir.The object of the present invention is to provide a power reserve indication device for watches with double barrels, both those with manual winding and those with automatic winding. This object is achieved by a power reserve device, comprising two barrels, one called winding and the other said disarming, a star wheel secured to a display means, characterized in that the barrel armament comprises a winding pin actuating a winding lever driving in positive rotation the star wheel, the disarming barrel comprises a disarming pin actuating a disarming lever driving in negative rotation the star wheel, the latter being held in its position by a jumper.
La présente invention s'applique premièrement aux montres équipées de deux barillets. La particularité du mécanisme à double barillets réside dans le fait que lors de l'armage, seul un barillet est en rotation, le second restant immobile. Inversement, lors du désarmage, le deuxième barillet est en rotation alors que le premier reste immobile.The present invention applies firstly to watches equipped with two barrels. The peculiarity of the double barrel mechanism lies in the fact that during winding, only one barrel is in rotation, the second remaining stationary. Conversely, during disarming, the second barrel is in rotation while the first remains stationary.
La grande autonomie du système à double barillets rend utile de disposer d'un affichage de réserve de marche. Pour cela on utilise le mécanisme existant du double barillets avec l'adjonction de deux leviers. L'adjonction du mécanisme d'indication de réserve de marche affectera les barillets ainsi que l'affichage.The great autonomy of the double barrel system makes it useful to have a power reserve display. For this we use the existing mechanism of double barrels with the addition of two levers. The addition of the power reserve indication mechanism will affect the barrels as well as the display.
Le remontage s'effectue en tournant la couronne de remontoir, le pignon coulant étant dans sa position d'engrenage avec le pignon de remontoir. Ce dernier engrène avec la roue de couronne entraînant elle-même le rochet (fixé sur l'arbre de barillet de désarmage). Les barillets sont ainsi armés et exécutent leur fonction première à savoir: emmagasiner l'énergie nécessaire au fonctionnement de la montre. Une goupille d'armage a été fixée sur le barillet d'armage. Suivant le mouvement de rotation de ce barillet, la dite goupille entre en contact avec un levier dont le basculement à son extrémité opposée, actionnera la roue-étoile sur laquelle se situe l'affichage.The winding is carried out by turning the winding crown, the sliding pinion being in its gear position with the winding pinion. The latter meshes with the crown wheel itself driving the ratchet (fixed on the disarming barrel shaft). The barrels are thus armed and perform their primary function, namely: storing the energy necessary for the operation of the watch. A winding pin has been attached to the winding barrel. According to the rotational movement of this barrel, said pin comes into contact with a lever, the tilting of which at its opposite end, will actuate the star wheel on which the display is located.
Le remontage s'effectue à l'aide d'une masse oscillante, dont la rotation est assurée par les mouvements du bras et à travers une combinaison de cliquets et de rouages, et arme le ressort. Le barillet est ainsi armé et exécute sa fonction première à savoir : emmagasiner l'énergie nécessaire au fonctionnement de la montre. Une goupille d'armage a été fixée sur le barillet d'armage. Suivant le mouvement de rotation de ce barillet, la dite goupille entre en contact avec un levier dont le basculement, à son extrémité opposée, actionne la roue-étoile sur laquelle se situe l'affichage.The reassembly is carried out using an oscillating mass, whose rotation is ensured by the movements of the arm and through a combination of pawls and cogs, and arms the spring. The barrel is thus armed and performs its primary function, namely: to store the energy necessary for watch operation. A winding pin has been attached to the winding barrel. According to the rotational movement of this barrel, said pin comes into contact with a lever whose tilting, at its opposite end, actuates the star wheel on which the display is located.
Les deux leviers, soit le levier d'armage et le levier de désarmage, sont désengagés de la roue étoile par des ressorts de rappel. Ceci permet de laisser libre la roue-étoile pour l'action du levier qui est en cours de basculement.The two levers, the winding lever and the disarming lever, are disengaged from the star wheel by return springs. This allows the star wheel to be left free for the action of the lever which is being tilted.
Un sautoir en appui sur la roue-étoile garantit à cette dernière son maintien dans la position définie par l'action des leviers.A jumper resting on the star wheel guarantees that it remains in the position defined by the action of the levers.
Chacun des leviers est monté sur un axe de pivotement, un des côtés étant positionné en face de la denture de la roue-étoile, l'autre côté étant placé en regard de la goupille du barillet.Each of the levers is mounted on a pivot axis, one of the sides being positioned opposite the toothing of the star wheel, the other side being placed opposite the pin of the barrel.
L'invention sera mieux comprise grâce à la description détaillée qui va suivre en se référant aux dessins annexés dans lesquels :The invention will be better understood thanks to the detailed description which follows, with reference to the appended drawings in which:
- La figure 1 représente un indicateur de réserve de charge avec son mécanisme d'armage,FIG. 1 represents a charge reserve indicator with its winding mechanism,
La figure 2 représente un indicateur de réserve de charge avec son mécanisme de désarmage,FIG. 2 represents a charge reserve indicator with its disarming mechanism,
La figure 3 représente une vue de dessus illustrant les deux mécanisme d'armage et de désarmage,FIG. 3 represents a top view illustrating the two arming and disarming mechanisms,
La figure 4 représente, en coupe, l'indicateur de réserve de charge avec son mécanisme de rotation positive/négative et deux barillets superposés.Figure 4 shows, in section, the charge reserve indicator with its positive / negative rotation mechanism and two superimposed barrels.
La figure 5 représente l'indicateur de réserve de charge avec son mécanisme de rotation positive/négative et deux barillets côte à côte. La figure 1 décrit la partie propre à l'armage des barillets avec son mécanisme d'entraînement d'une roue d'indication (roue-étoile) 3 par un levier d'armage 4.Figure 5 shows the charge reserve indicator with its positive / negative rotation mechanism and two barrels side by side. FIG. 1 describes the part specific to winding the barrels with its mechanism for driving an indication wheel (star wheel) 3 by a winding lever 4.
Un premier levier dit levier d'armage 4 est monté sur un axe de pivotement 11 solidaire d'un pont non représenté. L'une des extrémités de ce levier 4, dispose d'une goupille 14, l'autre extrémité étant terminée par un ergot 13 de fonction d'entraînement. Ce levier d'armage 4 est maintenu dans sa position de repos par un ressort de rappel 6 appuyant sur la goupille 12, ledit ressort ayant comme fonction de ramener le levier d'armage 4 dans sa position de repos, c'est-à-dire hors de la circonférence de la roue-étoile 3. L'impulsion donnée par la goupille 14 permet la rotation de la roue-étoile d'une dent dans le sens positif (sens d'armage).A first lever, said winding lever 4, is mounted on a pivot axis 11 secured to a bridge, not shown. One end of this lever 4 has a pin 14, the other end being terminated by a lug 13 of the drive function. This winding lever 4 is held in its rest position by a return spring 6 pressing on the pin 12, said spring having the function of returning the winding lever 4 to its rest position, that is to say say outside the circumference of the star wheel 3. The impulse given by the pin 14 allows the rotation of the star wheel of a tooth in the positive direction (winding direction).
Le barillet d'armage 1 dispose d'une goupille d'armage 9 placée sur la périphérie du barillet 1. A chaque tour de ce barillet, la goupille d'armage 9 entraîne l'ergot 13 du levier d'armage 4, ledit levier venant par pivotement, s'engager dans la denture de la roue-étoile 3 grâce à la goupille 14 d'entraînement.The winding barrel 1 has a winding pin 9 placed on the periphery of the barrel 1. At each turn of this barrel, the winding pin 9 drives the lug 13 of the winding lever 4, said lever coming by pivoting, engage in the toothing of the star wheel 3 by means of the drive pin 14.
Sur la figure 2, la partie responsable de l'armage a été volontairement enlevée. Le levier de désarmage 5 comprend à l'une de ses extrémités un ergot 15 représenté en pointillé sur la figure, entraîné par une goupille de désarmage 10 solidaire du barillet 2 de désarmage. A chaque rotation de ce barillet 2, le levier de désarmage 5 bascule autour de son axe de pivotement 11 et entraîne la roue-étoile 3 d'une dent dans le sens dit négatif (sens de désarmage).In Figure 2, the party responsible for the armouring has been voluntarily removed. The disarming lever 5 comprises at one of its ends a lug 15 shown in dotted lines in the figure, driven by a disarming pin 10 secured to the disarming barrel 2. At each rotation of this barrel 2, the disarming lever 5 rocks around its pivot axis 11 and drives the star wheel 3 of a tooth in the so-called negative direction (disarming direction).
Ce levier de désarmage 5 est maintenu dans sa position de repos par un ressort de rappel 7 appuyant par l'intermédiaire d'une goupille 16, ledit ressort ayant comme fonction de ramener le levier de désarmage 5 dans sa position de repos, c'est-à-dire hors de la circonférence de la roue-étoile 3.This disarming lever 5 is held in its rest position by a return spring 7 pressing by means of a pin 16, said spring having the function of returning the disarming lever 5 to its rest position, it is i.e. outside the circumference of the star wheel 3.
La fonction du sautoir 8 est d'une part de garantir le maintien de la roue-étoile 3 dans sa position d'indication et d'autre part de participer au basculement. En effet, à chaque impulsion soit de la goupille d'armage 14, soit l'extrémité du levier de désarmage 5, le sautoir 8 permet de terminer la course d'une dent.The function of the jumper 8 is on the one hand to guarantee the maintenance of the star wheel 3 in its position of indication and on the other hand to participate in the tilting. Indeed, at each pulse either of the winding pin 14, or the end of the disarming lever 5, the jumper 8 allows the stroke of a tooth to be ended.
La figure 3 représente une vue de dessus du mécanisme complet avec ses deux leviers. Ces derniers sont montés sur un même axe 11 et on peut observer la double fonction d'armage et de désarmage.Figure 3 shows a top view of the complete mechanism with its two levers. These are mounted on the same axis 11 and we can observe the dual function of arming and disarming.
La figure 4 est une coupe du montage selon un plan déterminé par les axes des barillets et de la roue-étoile. L'axe de la roue-étoile 3 est solidaire des moyens d'affichage de la réserve de marche, dans notre cas un tambour gradué 17. Ce dernier, au travers d'un guichet servant de repère fixe, indiquera la réserve de marche de la montre.Figure 4 is a section of the assembly along a plane determined by the axes of the barrels and the star wheel. The axis of the star wheel 3 is integral with the means of displaying the power reserve, in our case a graduated drum 17. The latter, through a window serving as a fixed reference, will indicate the power reserve of the watch.
On peut observer les deux barillets montés coaxialement et sur chacun de ceux-ci, est placé une goupille d'entraînement. Le levier d'armage 4 prend son mouvement sur la goupille 9 solidaire du barillet supérieur 1. D'autre part, le levier de désarmage 5 prend son mouvement sur la goupille 10 solidaire du barillet inférieur 2.We can observe the two barrels mounted coaxially and on each of them is placed a drive pin. The winding lever 4 takes its movement on the pin 9 secured to the upper barrel 1. On the other hand, the disarming lever 5 takes its movement on the pin 10 secured to the lower barrel 2.
L'emplacement des goupilles sur les barillets n'est pas important en soi, que ce soit sur la planche du barillet tel qu'illustré sur le barillet de désarmage 2, ou sur le tambour tel qu'illustré sur le barillet d'armage .The location of the pins on the barrels is not important in itself, whether on the barrel board as illustrated on the disarming barrel 2, or on the drum as illustrated on the cocking barrel.
La figure 5 représente une variante de l'invention avec les deux barillets montés sur un même plan. Le système de l'invention s'applique également dans ce cas, la différence principale résidant dans le fait que chaque levier dispose de son axe propre, soit 1 V et 11".FIG. 5 represents a variant of the invention with the two barrels mounted on the same plane. The system of the invention also applies in this case, the main difference residing in the fact that each lever has its own axis, ie 1 V and 11 ".
On retrouve les mêmes éléments à savoir les goupilles sur les barillets 1 et 2 qui provoquent le basculement de chaque levier respectif.We find the same elements namely the pins on the barrels 1 and 2 which cause the tilting of each respective lever.
II est à noter que d'autres formes d'affichage peuvent être utilisées dans le cadre de cette invention; par exemple à l'aide d'une simple aiguille située sur la roue-étoile, les repères d'indication de réserve de charge étant dans ce cas fixés sur un cadran. De plus, le nombre de goupilles par barillet peut être supérieur à un selon le mode d'affichage choisi. En effet, si le nombre de dents de la roue-étoile est important, il peut être souhaitable de provoquer l'entraînement de deux dents par tour de barillet. It should be noted that other forms of display can be used in the context of this invention; for example using a simple needle located on the star wheel, the load reserve indication marks in this case being fixed on a dial. In addition, the number of pins per barrel can be greater than one depending on the display mode chosen. Indeed, if the number of teeth of the star wheel is large, it may be desirable to cause the drive of two teeth per barrel revolution.
