Definitions
- the present invention relates to a device comprising a usual time movement and a chronograph module according to the preamble of the independent claim 1.
- Wristwatches whose box houses a module or chronograph movement provided with a quartz oscillator allow the wearer to make measurements with a precision that varies according to the type of display, namely of the order of one tenth or hundredths of a second, depending on whether this display is analog or digital respectively.
- CH-667.771 discloses a chronograph watch comprising a usual central clockwork movement involving hour, minute and second hands and an autonomous chronograph movement having a timepiece and at least one indicator driven by an electric motor.
- the organs of the chronograph movement are arranged on the periphery of the usual movement or basic movement. Each movement has its own oscillating regulator at the same frequency as the other.
- the chronograph movement is provided with an independent bell-shaped cage covering the basic watch movement and surrounding it. The two movements are connected by means of a plate interposed between them.
- the document EP1043636 describes for example a mechanical chronograph based on common time for the hour part and the chronograph part, with a common central barrel.
- the document EP1024416 describes a mechanism for displaying the fractions of a second of a chronograph, with a precision preferably between 1/5 th of a second and the tenth of a second, thanks to an actuating mechanism comprising a co-coax cooperating with the hourly movement of based.
- the document EP0806712 describes a chronograph comprising a separate barrel for an alarm mechanism so as not to affect the power reserve of the watch. This invention does not relate to chronography and does not improve the accuracy of a chronograph.
- a timepiece more particularly a wristwatch housing a device comprising a basic time movement and a "all mechanical" chronograph movement
- Its price is therefore high, even though the precision of its chronograph movement is mediocre, not even reaching that of a low-end digital display chronograph quartz movement.
- the creation of a timepiece housing a dual movement, both mechanical and mechanical, both chronographically and chronographically confronts the manufacturer with a delicate problem of space or volume of the piece, a problem that , failing a solution, will result in an unsightly that could compromise the commercial success of the watch.
- the document EP620509 describes the combination of a basic module and auxiliary chronograph modules.
- the main purpose is to reduce the overall thickness of the device, but the auxiliary modules are always driven by PTOs of the basic movement.
- the object of the present invention is to provide a device that overcomes the disadvantage of the lack of precision while ensuring, in addition, a truly reliable reading regardless of the characteristic of the chosen regulator, therefore the expected accuracy, and excluding any disturbances (explained above) on the time part of the movements of the device.
- the device according to the invention advantageously finds its place in a chronograph wristwatch (not specifically referenced), as shown in FIG. figure 1 .
- This watch presents: at 2 o'clock, a pusher crown 1 making it possible to assemble a cylinder of the chronograph module of the device - module hereinafter called autonomous chronograph module MCA - and to control the start and stop functions of the autonomous chronograph module MCA, at 3 o'clock, a winding crown 2 of the time movement of the device, movement hereinafter referred to as basic movement MB, and at 4 o'clock a push button 3 activated for the reset and the return on the fly of the autonomous chronograph module MCA.
- the chronograph watch allows the display of the current time using a hand of hours 4, a minute hand 5 and a small second needle 6 arranged at three o'clock. It also makes it possible to display the measurement of an elapsed time using a thirty-minute counter 7 placed at nine o'clock and provided with a hand 8, a central chronograph hand 9 and a a counter of the hundredths of seconds 10 located at six o'clock and provided with a needle 11.
- a power reserve counter 12 of the autonomous chronograph module MCA equipped with a needle 13 and located at twelve o'clock serves to verify the autonomy of said module up to at the next winding.
- the graduations of these different counters are carried on a dial 14; in particular, the hundredths of a second correspond to one hundred marks materialized on a circular rule, the needle 11 effecting a rotation of 360 ° per second to ensure a comfortable and accurate reading of the time interval.
- the Fig. 2 is a perspective view showing the principle of assembly of the autonomous chronograph module MCA with the basic movement MB, providing centering elements and fasteners.
- a basic board 76 of the module Autonomous chronograph MCA has two holes (not visible and not referenced) in which cylindrical feet 16, 17 are disengaged for engaging in dial gauge holes 18, 19 of a plate 15 of the basic movement MB, for correct angular positioning of the MCA module relative to the movement MB.
- Fixing means connect the basic movement MB and the autonomous chronograph module MCA at their periphery. According to the example, screws 20 A, 21 A pass through holes (not visible and not referenced) made in the board 76 and are screwed into corresponding threaded holes 20, 21 of the plate 15.
- a push rod 1 A intended to receive the push crown 1 ( figure 1 ) and, emerging from its face from above, a shaft 71 of the mobile minutes, a shaft 67 of the seconds mobile, a shaft 61 of the mobile hundredths of a second and a shaft 88 of the small second, and secondly, on the base module MB, disengaging from its side, a push rod 2 B intended to receive the winding crown 2 ( figure 1 ) and emerging from its top face, in the center, a wheel 86 of the seconds mobile and a wheel 77 of the minutes mobile.
- the Fig. 3 is a perspective view of the two movements in the assembled state, essentially showing the autonomous chronograph module MCA covering the basic movement MB (visualized mainly by its plate 15 and its winding stem 2B) and illustrating the remarkable layout and conformation and original of the main bodies and elements of the MCA standalone chronograph module on its base board 76.
- This extremely compact and compact arrangement results from an optimal exploitation of volumes, which saves expensive miniaturization of said bodies and elements without sacrificing aesthetics, this design and construction to limit the dimensions of the device in the assembled state to very small values.
- these values are of the order of 7.75 mm (height) and 30 mm (overall diameter), the dimensions of the single chronograph module MCA not exceeding values of the order of 4 mm (height) and 30 mm (diameter). We understand that these dimensions allow skins of the device of the most varied and a remarkable and successful aesthetics.
- the autonomous chronograph module MCA is provided with its own barrel 22 and its own regulator member including a rocker 23. This feature eliminates any power take-off on the base movement MB and stops the balance 23 without disturbing the balance- spiral of the basic movement MB.
- the chronograph MCA is triggered and triggered by short pressure on the push rod 1 A, that is to say on the crown 1.
- Each of these pressures produces a displacement towards the center of the chronograph MCA of a plate 24 comprising grooves in the form of oblong openings 25, 26, this displacement, guided by screws 27, 28 cooperating with said grooves, simultaneously activating a spout 29.
- the plate 24 and the spout 29 take up their starting position under the action respectively of a wire spring 40 and a return spring 41.
- a new pressure on the crown 1 leads to the stop of the chronograph at the end of an identical but inverse process (position corresponding to that illustrated in the figure 3 (Pendulum in motion)), the leaf spring 38 entering this time tangentially in contact with the outer face of the beam 23 and immobilizes the latter.
- This reset is done by action of a single hammer 48.
- the aforementioned pressure on the button 3 rotates a rocker 42 and therefore its spout 44 around a pillar axis 43, which has the effect of causing an inverter 45 with its pin 46, the latter in turn controlling a lever 47 which pivots the hammer 48 whose three spouts (not referenced) strike hearts 49, 50, 51 respectively mounted on the mobiles of the minutes counters, seconds and hundredths of a second (see also figure 4 ) and reset the MCA chronograph module.
- the spout 44 When pressing on the rocker 42, the spout 44 remains in contact with the inverter 45 for about two-thirds of the angular space described by the rocker 42 about the pillar axis 43, then said spout 44 separates tangentially from the end of the inverter 45 and the inverter 45 returns to its starting point under the action of a return spring wound around the pivot axis of said inverter 45 (on the figure 3 neither this return spring nor this pivot axis are referenced, the pivot axis being moreover hidden by the inverter 45).
- the hammer 48 is fixed to the axle 52 by a screw 53 and an eccentric washer 54.
- the eccentric washer 54 makes it possible to adjust the adjustment of the hammer 48 so that the three jaws of said hammer 48 simultaneously press on the three cores 49, 50 and 51, the resetting of the chronograph module MCA is thus done just before the spout 44 leaves the inverter 45.
- the spout 44 When releasing the pressure on the latch 42, the spout 44, held by a return spring 56, can pivot about a pin 55 to avoid the inverter 45 and allow the latch 42 to resume its rest position under the effect of a return spring 57.
- the operating principle described above thus serves to avoid, during the resetting of the autonomous chronograph module MCA and the rocker 23 being in motion, any stop of said pendulum due to prolonged friction of the shafts 61, 67 and 71.
- the same pressure exerted on the press button 3 causes, when the rocker 23 is stopped, a resetting of the chronograph module MCA and, when the rocker 23 is in motion, a reset of the chronograph module MCA (operation referred to as flyback) followed by an automatic restart a new measurement (no obligation to press on the push rod 1 A).
- the spiral balance assembly of the regulating organ of the chronograph is stopped when the latter is not in operation.
- the Fig. 4 is a perspective view illustrating the arrangement of the regulating member, the gear train and the barrel mounted on the base board 76 of the autonomous chronograph module MCA.
- the balance spring assembly 23 is sized to oscillate at a frequency of 360,000 vibrations per hour.
- the solution therefore consists in adopting a compromise between a reduction in the outer diameter of the balance, which facilitates its integration into the autonomous chronograph module MCA, and an increase in the power of acceleration of the hairspring defined by its CGS number.
- a hairspring will therefore be chosen whose technical characteristics allow the choice of a balance of a dimension such that the controller oscillates at the predetermined frequency, that the regulating member offers a good quality of adjustment and that the pendulum can be relaunched effectively by the leaf spring 38.
- a wheel 59 driven on the shaft of the escape wheel 58 is chosen so that it rotates at a speed of 2.5 turns per second, the balance 23 oscillating, according to the example, at 50 Hz (ie 360'000 vibrations per hour).
- a wheel 60 of the mobile hundredths of a second turns clockwise at the speed of one revolution per second.
- a wheel (not visible in the figure, because hidden by the heart 51), integral with the wheel 60, is mounted on the shaft 61 of the mobile hundredths of a second and meshes with a wheel 62 driven on a pinion 63, the latter meshing with a wheel 64.
- a wheel 65 of the seconds wheel rotates clockwise at the speed of one revolution per minute by means of an inverter 66 which connects it to the wheel 64.
- a wheel 84 (shown in FIG. figure 5 ) hidden by the heart 50 and secured to the wheel 65 is mounted on the shaft 67 of the mobile seconds. This wheel 84 meshes with a wheel 68 driven on a shaft integral with a wheel 69 which drives a wheel 70 mounted on the shaft 71 of the mobile minutes.
- the wheel 70 rotates clockwise at the speed of one revolution in thirty minutes, it meshes with a wheel 72 driven on a shaft 73 secured to a wheel 74 which meshes with a ring gear 75 of the barrel 22, the latter being unwound under the action of the mainspring (not shown) clockwise at the speed of one revolution in 29.7 minutes.
- the mainspring In a mechanical movement, the mainspring is generally calculated to perform about 7.5 turns. According to the embodiment described, for reasons of space saving, the mainspring is sized to allow the barrel to perform about six turns, which equates to a power reserve of 178.2 minutes.
- the present invention also provides the possibility of modifying the spiral balance oscillation frequency, the measurement resolution and the reserve. of the MCA standalone chronograph module.
- the oscillation frequency provided by the controller of the autonomous chronograph module MCA is equal to N times the oscillation frequency supplied by the basic movement regulating member MB, for example, for a movement of based on a frequency of 28,800 vibrations per hour, N can be chosen at 12.50, so that the MCA standalone chronograph module beats the hundredth of a second.
- the Fig. 5 illustrates one of the many ways to transfer the time information, provided by the basic movement MB through the autonomous chronograph module MCA, to the hour hands 4, 5 and 6 disposed on the dial 14 ( figure 1 ).
- the wheel 77 mounted on the floor of the basic movement MB meshes with a return 78 driven on a shaft 79 integral with the returns 80, 81.
- the reference 80 causes a roadway 82 carrying the minute hand 5 and mounted freely on a tube 85, while the reference 81 drives a gun wheel 83 carrying the hour hand 4.
- a wheel 86 mounted on the seconds shaft of the base movement MB meshes with a return 87 which drives a wheel 89 driven on a small seconds 88 tree located at three o'clock.
- a wire spring (not shown) can press inside a groove 90 of the shaft 88 of the small second.
- This arrangement makes it possible to arrange - according to common practice - the shaft 67 of the chronograph second hand 9 in the center of the MCA module (see also figure 4 ) and offers the user a display of the time interval measured by the MCA standalone chronograph module.
- the figure 8 (comparable with figure 2 ) represents a variant according to which a seconds tree 67 B, a roadway 82 B and a base wheel 83 B of the base movement MB have been lengthened so as to pass through a central opening 115 of the autonomous chronograph module MCA and to display the hour, minute and second at the center of the dial 14.
- the second hand of the autonomous chronograph movement MCA is carried by a shaft 88 A arranged at three o'clock on a counter.
- the Fig. 6 is a perspective view of the winding system of the self-winding chronograph module MCA mounted on the base board 76.
- the manual winding of the barrel 22 is performed by rotating the push rod 1 A, in the rest position, in the same clockwise direction than that necessary for the manual winding of the basic mechanical movement MB, necessary to put it into service again when it has not been worn for a sufficiently long period and when the mainspring is fully unwound (automatic movement).
- the push rod 1 A is guided by a stud 91 and held in place by a leaf spring 92.
- a pressure exerted from below on the end of a lug 93 releases the push rod 1 A and allows to remove the movement of its case shown at figure 1 and not referenced, provided that the same operation is performed on the winding stem 2 B (not shown in this figure).
- An angle wheel 94 actuated by a drive square 95 of the push rod 1 A causes a return 96 which meshes with a clutch wheel 97.
- This wheel 97 is engaged with a return 98 if it turns in the direction counterclockwise around its shaft 114, or disengaged from this reference 98 if it rotates clockwise, the shaft 114 being truncated in the form of almond.
- the return 98 driven by the clutch wheel 97 when it turns counterclockwise, meshes with a reference 99 which actuates a ratchet 100 mounted on a bung 101 of the cylinder 22.
- the winding of the mainspring is therefore done by rotating the ratchet 100 clockwise (the system of snap required to conserve the energy stored by the mainspring during winding, known to those skilled in the art, is not shown).
- Fig. 7 represents in perspective an exemplary embodiment of a power reserve device of the autonomous chronograph module MCA, the power reserve information being displayed at noon on the frame 14 by the needle 12 ( figure 1 ).
- a ratchet 100 ( figure 6 ), during reassembly, causes an angular displacement of a power reserve shaft 102 about its axis, equivalent and of the opposite direction to that generated by a revolution of the ring 75 of the barrel 22 on the same shaft 102 during the running of the MCA standalone chronograph module.
- the ratchet 100 and the wheel 98 driven on the shaft 106 rotate at the same speed and in the same direction (time), a wheel 103, integral with a shaft 106, meshes with an external toothing of a solar corona 104, the internal toothing of the solar corona 104 drives a sun wheel 105, the wheel 105 being secured to a sun wheel 107 which is supported on an internal toothing of a solar corona 108 to rotate, in the direction counterclockwise, the shaft 102 of the power reserve at an angle of 30.375 degrees per ratchet turn 100.
- the ring 75 of the barrel 22 drives a wheel 109, this wheel 109 being secured to a pinion 110 and held by a return bridge 111.
- the pinion 111 meshes with an external toothing of the crown.
- solar 108 the internal toothing of the solar corona 108 drives the sun wheel 107 secured to the sun wheel 105 which rests on the internal toothing of the solar corona 104 to rotate, in the clockwise direction, the shaft 102 of the power reserve at an angle of 30.375 degrees per revolution of ring 75 of the barrel 22.
- the power reserve of the MCA standalone chronograph module is approximately one hundred twenty minutes, the barrel 22 makes a turn in 29.7 minutes, a barrel turn 22 corresponding to a rotation of 30.375 degrees of the shaft 102 of the power reserve.
- the approximate power reserve of the autonomous chronograph module MCA thus corresponds to a rotation angle of 127.72 degrees of the shaft 102 of the power reserve.
- a safety device can be provided which limits the rotation of the shaft 102 of the barrel.
- power reserve this device (not shown), which may consist for example of driving a pin-stop in a hole arranged on a planetary disc 112, this pin cooperating with an oblong opening concentric with the axis of the shaft 102 and arranged on a mechanism cover.
- the autonomous chronograph module MCA can be implemented as such, that is to say not necessarily associated with the basic movement MB.

Description
La présente invention porte sur un dispositif comprenant un mouvement horaire usuel et un module chronographe selon le préambule de la revendication indépendante 1.The present invention relates to a device comprising a usual time movement and a chronograph module according to the preamble of the
Le marché des montres chronographes dotées d'un dispositif de ce genre s'est considérablement développé au cours des dernières années, en particulier dans le segment haut de gamme. Cependant, une très grande partie de telles montres comporte une planche chronographe (appelée indifféremment, ci-après, partie, module ou mouvement chronographe), avec oscillateur à quartz, alors qu'une clientèle éprouve un attrait croissant pour des montres chronographes mécaniques. Mais avec ces dernières, pour des raisons explicitées plus loin, l'homme du métier se heurte notamment à un problème de précision (on parle aussi de résolution) de lecture.The market for chronograph watches equipped with such a device has grown considerably in recent years, particularly in the high-end segment. However, a very large part of such watches includes a chronograph board (hereinafter referred to alternatively as part, module or chronograph movement), with a quartz oscillator, while a customer is experiencing a growing attraction for mechanical chronograph watches. But with the latter, for reasons explained below, the skilled person is particularly faced with a problem of accuracy (we also speak of resolution) reading.
Les montres-bracelets dont la boîte abrite un module ou mouvement chronographe pourvu d'un oscillateurs à quartz permettent au porteur d'effectuer des mesures d'une précision qui varie selon le type d'affichage, à savoir de l'ordre du dixième ou du centième de seconde, selon que cet affichage est analogique ou digital respectivement.Wristwatches whose box houses a module or chronograph movement provided with a quartz oscillator allow the wearer to make measurements with a precision that varies according to the type of display, namely of the order of one tenth or hundredths of a second, depending on whether this display is analog or digital respectively.
Cette construction a pour but de réaliser une montre-chronographe électrique à bon compte. En revanche, la précision reste très discutable, l'aiguille chronographe battant le 1/5 de seconde (ce qui correspond à un oscillateur à 18'000 alternances par heure). En outre, ce document ne livre à l'homme du métier aucun enseignement quant à l'agencement des organes du module ou mouvement chronographe, dans l'hypothèse où ce module serait mécanique, ni à la coopération entre un module de ce type et le mouvement de base horaire usuel.This construction aims to make a cheap chronograph electric watch. On the other hand, the precision remains very questionable, the chronograph hand beating the 1/5 of a second (which corresponds to an oscillator with 18'000 vibrations per hour). In addition, this document does not provide the person skilled in the art any teaching as to the arrangement of the components of the module or chronograph movement, in the event that this module is mechanical, or the cooperation between a module of this type and the basic time base movement.
Or, cet agencement et cette coopération posent des problèmes complexes de fiabilité et de faisabilité sur les plans aussi bien technique qu'esthétique - que l'utilisation d'un chronographe à quartz ne résout nullement, mais en fait l'économie en les contournant - à tel point que l'homme du métier a toujours été dissuadé d'envisager ledit agencement et ladite coopération et a fortiori de s'assigner la tâche de les réaliser.However, this arrangement and this cooperation pose complex problems of reliability and feasibility in terms of both technical and aesthetic - that the use of a quartz chronograph does not solve at all, but in fact economics by circumventing them - so much so that one skilled in the art has always been discouraged from considering said arrangement and said cooperation and a fortiori to assign the task of realizing them.
De fait, la précision de mesure des chronographes mécaniques offerts actuellement sur le marché est, pour la plupart, de l'ordre de 0.125 seconde, le balancier correspondant oscillant à 28'800 alternances par heure, et plus rarement, pour certains autres chronographes mécaniques, sensiblement plus chers, dont le balancier oscille à 36'000 alternances par heure, de l'ordre de 0.1 seconde.In fact, the measurement accuracy of mechanical chronographs currently available on the market is, for the most part, of the order of 0.125 seconds, the corresponding balance oscillating at 28,800 vibrations per hour, and more rarely for some other mechanical chronographs , substantially more expensive, whose balance oscillates at 36,000 vibrations per hour, of the order of 0.1 seconds.

Cette précision de mesure ne peut être augmentée avec les chronographes mécaniques disposant d'une base de temps commune pour la partie horaire et la partie chronographe, cela pour plusieurs raisons. L'utilisation pour la partie horaire d'un balancier oscillant à une fréquence supérieure modifierait la vitesse de déroulement du ressort de barillet et diminuerait la durée de la réserve de marche du mouvement. De plus, un ensemble comprenant roue d'échappement, ancre, ellipse, pivot de balancier, qui serait soumis en continu à une telle condition de fonctionnement, accuserait après quelques mois déjà une usure importante provoquant inévitablement une altération irréversible du bon fonctionnement du mouvement. Il convient de souligner également qu'à haute fréquence, la transmission d'énergie du barillet au balancier-spiral à travers le rouage et l'échappement pose, en utilisation continue, des problèmes dont la solution impliquerait fort probablement la mise en oeuvre de moyens complexes et tout de même non exempts d'aléas. Ainsi, en guise d'illustration, un balancier oscillant à haute fréquence possède une amplitude plus faible que le même balancier oscillant à une fréquence plus basse. De ce fait, il sera plus sensible aux variations du couple moteur du ressort de barillet et n'offrira une stabilité de marche que pendant la période où la courbe de variation dudit couple moteur du ressort est linéaire.This measurement accuracy can not be increased with mechanical chronographs having a common time base for the time part and the chronograph part, for several reasons. Use for the hourly part a rocker oscillating at a higher frequency would change the unwinding speed of the mainspring and decrease the duration of the power reserve of the movement. In addition, an assembly comprising escapement wheel, anchor, ellipse, pendulum pivot, which would be subject to such a continuous operating condition, would, after a few months, already show significant wear inevitably causing irreversible deterioration of the smooth operation of the movement. It should also be emphasized that at high frequency, the transmission of energy from the barrel to the sprung balance through the gear train and the escapement poses, in continuous use, problems the solution of which would very likely imply the implementation of complex and still not free of hazards. Thus, by way of illustration, a high-frequency oscillating beam has a smaller amplitude than the same oscillating beam at a lower frequency. As a result, it will be more sensitive to variations in the engine torque of the mainspring and will offer stability during the period when the variation curve of said motor torque of the spring is linear.

Dans le prolongement de ces difficultés s'inscrivent celles que soulèvent les questions de coûts et d'esthétique. D'une part, on sait qu'une pièce d'horlogerie, plus particulièrement une montre-bracelet abritant un dispositif comportant un mouvement de base horaire et un mouvement chronographe "tout mécanique", est en principe classée dans le haut de gamme. Son prix est donc élevé, alors même que la précision de son mouvement chronographe est médiocre, n'atteignant pas même celle d'un mouvement chronographe à quartz à affichage digital de bas de gamme. D'autre part, on conçoit que la réalisation d'une pièce d'horlogerie abritant un double-mouvement, horaire et chronographe, tous deux mécaniques, confronte le manufacturier à un délicat problème d'encombrement ou de volume de la pièce, problème qui, à défaut de solution, se traduira par une inesthétique susceptible de compromettre le succès commercial de la montre. Une solution qui vient à l'esprit consisterait à miniaturiser les organes composant le chronographe mécanique. Mais en servant l'esthétique, elle irait en revanche à l'encontre de objectif du meilleur coût et soulèverait certainement des difficultés techniques majeures. La choisir et l'appliquer ne serait donc pas sans risques techniques et commercial. Ces risques apparaissant suffisamment dissuasifs pour inviter l'homme du métier à imaginer et investiguer d'autres pistes de solutions aux fins de réaliser le dispositif avec un rapport qualité / prix aussi avantageux que possible.In the wake of these difficulties are those raised by the questions of cost and aesthetics. On the one hand, it is known that a timepiece, more particularly a wristwatch housing a device comprising a basic time movement and a "all mechanical" chronograph movement, is in principle classified in the high-end. Its price is therefore high, even though the precision of its chronograph movement is mediocre, not even reaching that of a low-end digital display chronograph quartz movement. On the other hand, it is conceivable that the creation of a timepiece housing a dual movement, both mechanical and mechanical, both chronographically and chronographically, confronts the manufacturer with a delicate problem of space or volume of the piece, a problem that , failing a solution, will result in an unsightly that could compromise the commercial success of the watch. One solution that comes to mind is to miniaturize the components of the mechanical chronograph. But while serving aesthetics, it would, on the other hand, go against the objective of the best cost and would certainly raise major technical difficulties. To choose and apply it would not be without technical and commercial risks. These risks appear sufficiently dissuasive to invite the skilled person to imagine and investigate other possible solutions for the purpose of achieving the device with a quality / price ratio as advantageous as possible.

Le but de la présente invention est de proposer un dispositif qui pallie l'inconvénient du manque de précision tout en assurant, en outre, une lecture véritablement fiable quelle que soit la caractéristique du régulateur choisi, donc de la précision prévue, et excluant toutes perturbations (exposées plus haut) sur la partie horaire des mouvements du dispositif.The object of the present invention is to provide a device that overcomes the disadvantage of the lack of precision while ensuring, in addition, a truly reliable reading regardless of the characteristic of the chosen regulator, therefore the expected accuracy, and excluding any disturbances (explained above) on the time part of the movements of the device.
Ce but est atteint grâce aux moyens définis dans la revendication indépendante 1, les revendications dépendantes portant sur des moyens permettant des réalisations préférées de l'invention et, dans le droit fil du rapport qualité / prix évoqué plus haut, à bon compte.This object is achieved by the means defined in the

En d'autres termes, le dispositif selon l'invention permet d'offrir une pièce d'horlogerie haut de gamme véritablement "tout mécanique", dont la précision du chronographe n'a rien à envier à un chronographe à quartz de haute qualité.The tests carried out on prototypes according to the invention equipped with a chronograph whose balance oscillated at 360,000 vibrations per hour made it possible to establish that a precision of one hundredth of a second was ensured even in continuous use of at least thirty minutes. In other words, the device according to the invention makes it possible to offer a truly "all-mechanical" high-end timepiece, whose chronograph precision has nothing to envy to a high-quality quartz chronograph.

Pour réduire davantage encore la hauteur du mouvement chronographe, on peut envisager de disposer les éléments - sur lesquels on reviendra en détail plus loin (notamment organes régulateurs, barillets, rouages respectifs, réserve de marche, leviers, systèmes de remontage) - sur des ponts agencés de manière adéquate, à partir d'une platine unique, les mouvements de base et chronographes étant alors imbriqués l'un dans l'autre, cela sans entraver le bon fonctionnement du module chronographe selon les processus qui vont être décrits ci-après, mais en renchérissant les coûts de fabrication.To further reduce the height of the chronograph movement, we can consider arranging the elements - which will be discussed in detail later (including regulators, barrels, respective wheels, power reserve, levers, winding systems) - on bridges suitably arranged, from a single plate, the basic movements and chronographs then being nested one into the other, without hindering the proper operation of the chronograph module according to the processes that will be described below, but by increasing the manufacturing costs.
Le module chronographe autonome MCA est pourvu de son propre barillet 22 et de son propre organe régulateur comprenant notamment un balancier 23. Cette caractéristique supprime toute prise de force sur le mouvement de base MB et permet d'arrêter le balancier 23 sans perturber le balancier-spiral du mouvement de base MB.The autonomous chronograph module MCA is provided with its
Le chronographe MCA est enclenché et déclenché par courte pression sur la tige de poussoir 1 A, c'est-à-dire sur la couronne 1. Chacune de ces pressions produit un déplacement en direction du centre du chronographe MCA d'une plaque 24 comportant des rainures en forme d'ouvertures oblongues 25, 26, ce déplacement, guidé par des vis 27, 28 coopérant avec lesdites rainures, mettant simultanément en action un bec 29. Lorsque la pression est relâchée, la plaque 24 et le bec 29 reprennent leur position de départ sous l'action respectivement d'un ressort-fil 40 et d'un ressort de rappel 41.The chronograph MCA is triggered and triggered by short pressure on the
En partant d'une position de départ (chronographe arrêté, c'est-à-dire à zéro), l'extrémité du bec 29, pivotant autour d'une goupille 30, entre en contact avec un flanc d'une aile centrale d'une came 31 et fait tourner ladite came 31 autour d'un arbre 32 d'un angle défini par une butée 33. Un ergot 34 entraîne alors un levier 35, un ergot 39 fait pivoter un lanceur 36 autour de son arbre 37, et une lame-ressort 38 se dégage tangentiellement de la face extérieure du balancier 23. Ce faisant, le ressort 38 fournit au balancier 23 une impulsion de départ pour le mettre en mouvement. Une nouvelle pression sur la couronne 1 conduit à l'arrêt du chronographe au terme d'un processus identique mais inverse (position correspondant à celle qui est illustrée à la
Une pression exercée sur le bouton poussoir 3 (
Cette remise à zéro se fait par action d'un marteau unique 48. La pression précitée sur le bouton 3 fait pivoter une bascule 42 et par conséquent son bec 44 autour d'un axe de pilier 43, ce qui a pour effet d'entraîner un inverseur 45 avec sa goupille 46, cette dernière commandant à son tour un levier 47 qui fait pivoter le marteau 48 dont les trois becs (non référencés) viennent heurter des coeurs 49, 50, 51 montés respectivement sur les mobiles des compteurs des minutes, des secondes et des centièmes de seconde (voir aussi
Lors de la pression sur la bascule 42, le bec 44 reste en contact avec l'inverseur 45 pendant environ les deux tiers de l'espace angulaire décrit par la bascule 42 autour de l'axe de pilier 43, puis ledit bec 44 se sépare tangentiellement de l'extrémité de l'inverseur 45 et l'inverseur 45 revient à son point de départ sous l'action d'un ressort de rappel enroulé autour de l'axe de pivotement dudit inverseur 45 (sur la
Le marteau 48 est fixé au pont de rouage 52 par une vis 53 et une rondelle excentrique 54. La rondelle excentrique 54 permet d'ajuster le réglage du marteau 48 de manière que les trois becs dudit marteau 48 appuient simultanément sur les trois coeurs 49, 50 et 51, la remise à zéro du module chronographe MCA s'effectuant ainsi juste avant que le bec 44 ne quitte l'inverseur 45.The
Les conséquences lors de la remise à zéro du module chronographe MCA diffèrent selon que le balancier 23 est arrêté ou en mouvement.The consequences of resetting the chronograph module MCA differ depending on whether the
Si le balancier 23 est arrêté, la lame-ressort 38 est en contact avec le balancier 23 et la friction exercée par les arbres 61, 67, 71 (
Par contre, si le balancier est en mouvement, la lame-ressort 38 n'est pas en contact avec le balancier 23 et la friction exercée par les arbres 61, 67 et 71 sur le rouage aura tendance à freiner le balancier 23.On the other hand, if the rocker is moving, the
Lors du relâchement de la pression sur la bascule 42, le bec 44, maintenu par un ressort de rappel 56, peut pivoter autour d'une goupille 55 pour éviter l'inverseur 45 et permettre à la bascule 42 de reprendre sa position de repos sous l'effet d'un ressort de rappel 57.When releasing the pressure on the
Le principe de fonctionnement décrit ci-dessus sert donc à éviter, lors de la remise à zéro du module chronographe autonome MCA et le balancier 23 étant en mouvement, tout arrêt dudit balancier dû à une friction prolongée des arbres 61, 67 et 71.The operating principle described above thus serves to avoid, during the resetting of the autonomous chronograph module MCA and the
Ainsi, une même pression exercée sur le bouton pressoir 3 (
L'ensemble balancier spiral de l'organe régulateur du chronographe est arrêté lorsque ce dernier n'est pas en fonction.The spiral balance assembly of the regulating organ of the chronograph is stopped when the latter is not in operation.

Dans la formule :
- f Fréquence [Hz]
- M Couple élastique du spiral [Nm]
- I Moment d'inertie du balancier [kg·m2]
- R rayon extérieur du balancier [m]
- r rayon intérieur du balancier [m]
- h épaisseur du balancier [m]
- ρ poids spécifique du balancier [kg/m3].
- f Frequency [Hz]
- M Elastic torque of the spiral [Nm]
- I moment of inertia of the pendulum [kg · m 2 ]
- R outside beam radius [m]
- r inner radius of the pendulum [m]
- h thickness of the pendulum [m]
- ρ specific weight of the balance [kg / m 3 ].
En introduisant des valeurs de f, R et r dans cette fonction on constate que si l'on fait passer la fréquence, par exemple de 28'800 à 360'000 alternances par heure, on pourrait diviser le diamètre du balancier par environ cinq. L'expérience montre qu'un balancier trop petit n'assure plus une bonne stabilité de marche et pose des problèmes de réglage. La solution consiste donc à adopter un compromis entre une réduction du diamètre extérieur du balancier, ce qui facilite son intégration dans le module chronographe autonome MCA, et une augmentation du pouvoir d'accélération du spiral défini par son numéro CGS.By introducing values of f, R and r into this function, it is found that if the frequency is changed, for example from 28,800 to 360,000 vibrations per hour, the diameter of the balance could be divided by about five. Experience shows that a rocker too small no longer ensures good stability and poses adjustment problems. The solution therefore consists in adopting a compromise between a reduction in the outer diameter of the balance, which facilitates its integration into the autonomous chronograph module MCA, and an increase in the power of acceleration of the hairspring defined by its CGS number.
Eu égard à ces considérations, on choisira donc un spiral dont les caractéristiques techniques autorisent le choix d'un balancier d'une dimension telle que le régulateur oscille à la fréquence prédéterminée, que l'organe régulateur offre une bonne qualité de réglage et que le balancier puisse être relancé efficacement par la lame-ressort 38.In view of these considerations, a hairspring will therefore be chosen whose technical characteristics allow the choice of a balance of a dimension such that the controller oscillates at the predetermined frequency, that the regulating member offers a good quality of adjustment and that the pendulum can be relaunched effectively by the
On aperçoit à la
Dans un mouvement mécanique, le ressort de barillet est généralement calculé pour réaliser environ 7,5 tours. Selon la forme d'exécution décrite, pour des raisons de gain de place, le ressort de barillet est dimensionné pour permettre au barillet d'effectuer environ six tours, ce qui équivaut à une réserve de marche de 178,2 minutes. Mais comme expliqué supra, l'utilisation d'un organe régulateur dont l'ensemble balancier spiral oscillant à haute fréquence (360'000 alternances par heure) réduit l'utilisation du couple moteur du ressort de barillet à la période durant laquelle la fonction Δ couple moteur / Δ temps est linéaire (voir diagramme ci-dessus), la réserve de marche utile du module chronographe autonome MCA est de l'ordre de cent vingt minutes.In a mechanical movement, the mainspring is generally calculated to perform about 7.5 turns. According to the embodiment described, for reasons of space saving, the mainspring is sized to allow the barrel to perform about six turns, which equates to a power reserve of 178.2 minutes. However, as explained above, the use of a regulating member whose high-frequency oscillating balance spring assembly (360,000 vibrations per hour) reduces the use of the driving torque of the mainspring spring to the period during which the function Δ torque motor / Δ time is linear (see diagram above), the power reserve of the MCA standalone chronograph module is of the order of one hundred and twenty minutes.
Lors d'une mesure à l'aide d'un chronographe mécanique usuel le rouage de la partie chronographe doit être débrayé du rouage de la partie horaire. Pour éviter le flottement des aiguilles de chronographe il est indispensable d'immobiliser les roues des mobiles porteurs desdites aiguilles. Avec le module chronographe mécanique autonome MCA selon la présente invention, cette opération d'immobilisation n'est pas nécessaire, car comme cela se dégage de le description plus haut du rouage du module chronographe autonome MCA, le train d'engrenage reste en permanence contraint par le ressort de barillet du fait qu'il n'y a pas de système de débrayage et que sur tous les mobiles porteurs de plusieurs roues (comme par exemple les roues 84 et 65 du mobile des secondes ou encore la roue d'échappement 58 et la roue 59 montées sur le même arbre), ces dernières sont solidaires. Ces caractéristiques garantissent une reprise permanente du jeu des engrenages.During a measurement using a conventional mechanical chronograph the wheel of the chronograph part must be disengaged from the gear of the time part. To avoid the floating chronograph hands it is essential to immobilize the wheels of the mobile carriers of said needles. With the autonomous mechanical chronograph module MCA according to the present invention, this immobilization operation is not necessary because, as is clear from the above description of the work train of the autonomous chronograph module MCA, the gear train remains permanently constrained. by the mainspring spring because there is no clutch system and that on all mobile carriers of several wheels (such as the
De plus, sur un chronographe usuel, les opérations d'embrayage du rouage de la partie chronographe avec le rouage de la partie horaire (mouvement de base MB ou renvois du mouvement de base situés dans ie module chronographe), et/ou de débrayage de ces rouages entre eux, provoque des sauts, en particulier lors de la mise en marche du chronographe, qui peuvent fausser la mesure de plusieurs dixièmes de secondes. Ce défaut est supprimé par la présente invention. Pour effectuer une remise à zéro des aiguilles de compteurs montées sur les arbres 61, 67 et 71 (
Comparativement à un chronographe mécanique comportant un module chronographe additionnel usuel dans lequel on peut modifier le rouage et la disposition des compteurs, la présente invention donne en plus la possibilité de modifier la fréquence d'oscillation du balancier spiral, la résolution de mesure et la réserve de marche du module chronographe autonome MCA. De manière générale, la fréquence d'oscillation fournie par le régulateur du module chronographe autonome MCA est égale à N fois la fréquence d'oscillation fournie par l'organe régulateur du mouvement de base MB, à titre d'exemple, pour un mouvement de base d'une fréquence de 28'800 alternances par heure, N peut être choisi à 12,50, de sorte que le module chronographe autonome MCA batte le centième de seconde. Ces caractéristiques permettent de réaliser une gamme de produits pratiquement illimitée couvrant tous les secteurs et créneaux économiques, allant de la montre chronographe grand public à celle de haute horlogerie, jusqu'à des produits réservés à des usages professionnels.Compared to a mechanical chronograph comprising a conventional additional chronograph module in which the gear train and the meter arrangement can be modified, the present invention also provides the possibility of modifying the spiral balance oscillation frequency, the measurement resolution and the reserve. of the MCA standalone chronograph module. In general, the oscillation frequency provided by the controller of the autonomous chronograph module MCA is equal to N times the oscillation frequency supplied by the basic movement regulating member MB, for example, for a movement of based on a frequency of 28,800 vibrations per hour, N can be chosen at 12.50, so that the MCA standalone chronograph module beats the hundredth of a second. These characteristics make it possible to produce a virtually unlimited range of products covering all sectors and economic niches, ranging from the chronograph watch for the general public to that of haute horlogerie, up to products reserved for professional use.

La roue 77 montée sur la chaussée du mouvement de base MB engrène avec un renvoi 78 chassé sur un arbre 79 solidaire des renvois 80, 81.

Une roue d'angle 94 actionnée par un carré d'entraînement 95 de la tige poussoir 1 A entraîne un renvoi 96 qui engrène avec une roue d'embrayage 97. Cette roue 97 est en prise avec un renvoi 98 si elle tourne dans le sens antihoraire autour de son arbre 114, ou bien débrayée de ce renvoi 98 si elle tourne dans le sens horaire, l'arbre 114 étant tronqué en forme d'amande. Le renvoi 98 entraîné par la roue d'embrayage 97 lorsqu'elle tourne dans le sens antihoraire, engrène avec un renvoi 99 qui actionne un rochet 100 monté sur une bonde 101 du barillet 22. Le remontage du ressort de barillet se fait donc par rotation du rochet 100 dans le sens horaire (le système d'encliquetage nécessaire à la conservation de l'énergie emmagasinée par le ressort de barillet lors du remontage, connue de l'homme de métier, n'est pas représenté).An

Lors de la marche du chronographe autonome MCA, la couronne 75 du barillet 22 entraîne une roue 109, cette roue 109 étant solidaire d'un pignon 110 et maintenue par un pont de renvoi 111. Le pignon 111 engrène avec une denture extérieure de la couronne solaire 108, la denture intérieure de la couronne solaire 108 entraîne la roue planétaire 107 solidaire de la roue planétaire 105 qui s'appuie sur la denture intérieure de la couronne solaire 104 pour faire tourner, dans le sens horaire, l'arbre 102 de la réserve de marche d'un angle de 30,375 degrés par tour de couronne 75 du barillet 22.During the running of the autonomous chronograph MCA, the
Selon cette forme de réalisation, la réserve de marche du module chronographe autonome MCA est d'environ cent vingt minutes, le barillet 22 fait un tour en 29,7 minutes, un tour de barillet 22 correspondant à une rotation de 30,375 degrés de l'arbre 102 de la réserve de marche. La réserve de marche approximative du module chronographe autonome MCA correspond donc à un angle de rotation de 127.72 degrés de l'arbre 102 de la réserve de marche.According to this embodiment, the power reserve of the MCA standalone chronograph module is approximately one hundred twenty minutes, the
Pour garantir que le remontage ou que la marche du module chronographe autonome MCA ne donnent pas lieu à un déroulement du ressort de barillet au delà des limites définies ci-dessus, on peut prévoir un dispositif de sécurité limitant la rotation de l'arbre 102 de réserve de marche, ce dispositif (non représenté), pouvant consister par exemple à chasser une goupille-butée dans un trou aménagé sur un disque planétaire 112, cette goupille coopérant avec une ouverture oblongue concentrique à l'axe de l'arbre 102 et aménagée sur un couvre-mécanisme.To ensure that the reassembly or the running of the autonomous chronograph module MCA do not give rise to unwinding the barrel spring beyond the limits defined above, a safety device can be provided which limits the rotation of the
Il va de soi que le module chronographe autonome MCA peut être mis en oeuvre en tant que tel, c'est-à-dire non nécessairement associé au mouvement de base MB.It goes without saying that the autonomous chronograph module MCA can be implemented as such, that is to say not necessarily associated with the basic movement MB.
