Definitions

  • Watch manufacturers are constantly seeking to vary the presentation of the time dial. For this purpose, many proposals have already been made to give the dial and turn of hours peculiar and unusual looks. In addition, additional indications relating to time are frequently displayed. Thus display devices give the day, the day of the week, the phases of the moon or the 24-hour time. Sometimes the watch has a second hour hand, adjustable to a time zone chosen at will. All these features are added to enrich the time display and make it more attractive.

Abstract

Timepiece including indicator members actuated or not actuated by the movement. These indicator members are composed of movable hour marks represented by the faces of the studs (30, 40) mounted on staffs having planet wheels (34) driven by a rack (50). The faces of the studs carry stones of various colors. When the movement operates the rack, it determines the change of the hour marks. When operation by the movement is disengaged, manual control elements allow the hour marks appearing on the dial to be changed.

Description

Pièce d'horlogerie munie d'un tour d'heures variableTimepiece with a variable time lapse
Les fabricants de montres cherchent constamment à varier la présentation du cadran-horaire. Dans ce but, de nombreuses propositions ont déjà été faites pour donner au cadran et au tour d'heures des allures particulières et inhabituelles. Par ailleurs, des indications supplémentaires, en rapport avec le temps, sont fréquemment affichées. Ainsi des dispositifs d'affichage donnent le quantième, le jour de la semaine, les phases de la lune ou l'heure sur 24 heures. Parfois la montre possède une seconde aiguille des heures, ajustable sur un fuseau horaire choisi à volonté. Tous ces dispositifs sont ajoutés pour enrichir l'affichage de l'heure et le rendre plus attractif. Sur les montres dites de moyenne ou de haut de gamme, il est fréquent que ces indications soient symbolisées par une pierre fine, semi- précieuse ou précieuse, par exemple un diamant. La totalité des indications horaires «1, 2, ..., 12 » peut être représentée matériellement ou seulement une partie d'entre elles par de telles pierres. De fait, dans de nombreux modèles de montre, la représentation du tour d'heures est symbolisée par quatre repères horaires, par exemple par la présence d'un diamant aux points horaires «12», «3 », « 6 » et « 9 », voire par un seul un diamant à l'endroit des douze heures.Watch manufacturers are constantly seeking to vary the presentation of the time dial. For this purpose, many proposals have already been made to give the dial and turn of hours peculiar and unusual looks. In addition, additional indications relating to time are frequently displayed. Thus display devices give the day, the day of the week, the phases of the moon or the 24-hour time. Sometimes the watch has a second hour hand, adjustable to a time zone chosen at will. All these features are added to enrich the time display and make it more attractive. On the so-called medium or high-end watches, it is common for these indications to be symbolized by a fine, semi-precious or precious stone, for example a diamond. The totality of the hourly indications "1, 2, ..., 12" can be represented physically or only a part of them by such stones. In fact, in many watch models, the representation of the hour clock is symbolized by four hourly markers, for example by the presence of a diamond at the time points "12", "3", "6" and "9". "Or even a single diamond at the place of twelve hours.
Ces indications représentant le tour d'heures sont statiques et, bien entendu, le détenteur d'une telle pièce d'horlogerie ne peut en aucun cas en modifier l'aspect. Pourtant, dans bien des situations, il peut être intéressant de faire varier ces indications grâce à un système évolutif. Les documents cités ci-après illustrent la recherche d'attractivité de l'affichage de l'heure par les horlogers.These indications representing the turn of hours are static and, of course, the holder of such a timepiece can in no way change its appearance. However, in many situations, it may be interesting to vary these indications through an evolutionary system. The documents cited below illustrate the search for attractiveness of time display by watchmakers.
Le brevet suisse CH 684' 814 décrit une pièce d'horlogerie avec des moyens qui permettent de modifier la présentation du tour d'heures. Une crémaillère est agencée pour coopérer avec une couronne et permettre la rotation. A l'endroit des points horaires sont prévus des plots libres en rotation, pourvus de' satellites en prise avec la crémaillère. Les faces de prismes montés sur ces plots sont serties de pierres précieuses, lesquelles apparaissent à travers des ouvertures ménagées dans la carrure ou le cadran.Swiss patent CH 684 '814 describes a timepiece with means that make it possible to modify the presentation of the hour circle. A rack is arranged to cooperate with a ring and allow rotation. At the location of the hourly points there are provided free rotating studs provided with satellites in engagement with the rack. The faces of prisms mounted on these studs are set with precious stones, which appear through openings in the caseband or dial.
Le brevet allemand DE 33' 129 décrit un cadran de montre qui permet de voir les vingt-quatre heures du jour. Une fenêtre, pratiquée à l'endroit où se trouve la mention de l'heure montre une face d'un corps ubique, muni d'un axe tenu par des paliers. Sur les faces sont inscrites les heures correspondantes de 1 à 12 et de 13 à 24. L'axe tenant ce corps est pourvu de goupilles que vient actionner à chaque tour d'horloge une tige, elle-même reliée à l'axe animant les aiguilles. Au passage de l'aiguille des heures, la face visible du corps tourne d'un quart de tour et passe, par exemple, d'une heure à treize heures.German patent DE 33 '129 describes a watch dial which allows to see the twenty-four hours of the day. A window at the place where the time is found shows a face of a ubic body, with an axis held by bearings. On the faces are written the corresponding hours of 1 to 12 and 13 to 24. The axis holding this body is provided with pins that comes to actuate at each clock tower a rod, itself connected to the axis animating the needles. At the passage of the hour hand, the visible face of the body turns a quarter of a turn and passes, for example, from one hour to thirteen hours.
Le brevet français FR 2 '776' 785 décrit un ensemble constitutif de l'habillement d'une montre comportant une boite de montre et un bracelet muni d'un fermoir pour le lier à la boîte et un organe mobile muni de quatre faces décoratives monté pivotant sur l'une des deux pièces. La pièce comportant l'organe mobile est muni d'une découpe laissant apparaître une de ses faces. L'immobilisation de l'organe mobile dans l'une ou l'autre de ses positions est réalisée en fixant le bracelet à la boîte. Par rapport à cet état de la technique, d'importants perfectionnements ont été conçus pour faire varier le tour d'heures:French Patent FR 2 776 785 describes a constituent assembly of the clothing of a watch comprising a watch case and a bracelet provided with a clasp to bind to the box and a movable member provided with four decorative faces mounted pivoting on one of the two pieces. The part comprising the movable member is provided with a cutout revealing one of its faces. The immobilization of the movable member in one or the other of its positions is achieved by fixing the bracelet to the box. Compared to this state of the art, important improvements have been designed to vary the hours:
• L' actionnement par le mouvement mécanique de la montre, débrayable et permettant des fonctions comme l'indication jour/nuit en changeant la face visible des heures;• Actuation by the mechanical movement of the watch, disengageable and allowing functions such as day / night indication by changing the visible face of the hours;

An actuating device 60 drives the circular rack 50. Plugs 30, 40 integral with the satellites 34, 44 are driven by the rack 50. A gemstone 35A ... 48A is mounted on each face of the studs 30, 40. Openings 16 in the dial 3 allow to see the stones. By actuating the device 60, different stones appear in the openings 16. In that the pads 30, 40 may be three or four faces and the satellites 34, 44 with nine or twelve teeth, the ordering of the stones according to the visible hours as a function of the rotation of the rack 50 comprises twelve possibilities.
Les figures 4A et 4B montrent le fonctionnement des plots en détail. Le plot 40 est visible sur la figure 4A montré avec sa tige 42 d'axe 43, son satellite 44 et son cube 41 montés sur la tige 42. Les arêtes et notamment les coins 49 sont arrondies, afin de pouvoir agencer le plot aussi près que possible de la branche 14 de la carrure 10, c'est-à-dire de l'ouverture 16. En effet, la courbure des arêtes obtenue par arrondissement des coins évitera au cube 41 d'entrer en conflit avec la partie 14 au voisinage de l'ouverture 16 lors de sa rotation. Dans la face 45 du cube 41, est inséré ou serti, par exemple un diamant 45A. Dans la face adjacente 46 est inséré un rubis 46A. Dans la face 47, opposée à la face 45 est insérée une émeraude 47 A. Dans la face 48, adjacente à la face 45 et opposée à la face 46, est inséré un saphir 48A. Comme il est dit plus haut, le satellite 44 coopère avec la denture 51 de la crémaillère 50. Selon l'exemple représenté sur la figure 4A, le satellite 44 présente douze dents.Figures 4A and 4B show the operation of the pads in detail. The stud 40 is visible in FIG. 4A shown with its stem 42 of axis 43, its satellite 44 and its cube 41 mounted on the rod 42. The edges and in particular the corners 49 are rounded so as to be able to arrange the stud as close as possible as possible of the branch 14 of the caseband 10, that is to say the opening 16. In fact, the curvature of the edges obtained by corner rounding will avoid the cube 41 to conflict with the part 14 to vicinity of the opening 16 during its rotation. In the face 45 of the cube 41, is inserted or crimped, for example a diamond 45A. In the adjacent face 46 is inserted a ruby 46A. In the face 47, opposite the face 45 is inserted an emerald 47 A. In the face 48, adjacent to the face 45 and opposite to the face 46 is inserted a sapphire 48A. As mentioned above, the satellite 44 cooperates with the toothing 51 of the rack 50. According to the example shown in FIG. 4A, the satellite 44 has twelve teeth.
La figure 4B montre un autre exemple de plot, de référence globale 30, non représenté dans l'exemple de disposition de la figure 3. Ce plot comprend une tige 32 d'axe 33.11 est libre en rotation autour de cet axe. Le corps du plot 30 présente la forme d'un prisme droit triangulaire 31, dont les arêtes 39 sont courbes, pour les mêmes raisons que celles déjà exposées à l'alinéa précédent à propos du plot 40. Les trois faces parallèles à l'axe 33 sont désignées par les références 35, 36, 37. Ces faces présentent respectivement, par exemple, un diamant 35A, un rubis 36A et une émeraude 37A. Un satellite 34 coopère avec la denture 52 de la crémaillère 50. Selon l'exemple représenté, le satellite 34 comporte neuf dents.FIG. 4B shows another example of a pad, of overall reference 30, not shown in the example of arrangement of FIG. 3. This stud comprises a rod 32 of axis 33.11 which is free to rotate around this axis. The body of the stud 30 has the shape of a right triangular prism 31, whose edges 39 are curved, for the same reasons as those already explained in the previous paragraph about the stud 40. The three faces parallel to the axis 33 are designated by the references 35, 36, 37. These faces have, for example, a diamond 35A, a ruby 36A and an emerald 37A. A satellite 34 cooperates with the toothing 52 of the rack 50. In the example shown, the satellite 34 has nine teeth.
La fig. 5A montre le dispositif d'actionnement 60 de la crémaillère 50 et un dispositif d'appui ou de frein 70. Le dispositif d'actionnement est guidé par la carrure 10 grâce à des alésages ajustés aux dimensions des portions 66, 67 de la tige 61 et portant cette pièce. Les caractéristiques d'engrenage des roues pilotes dentées 63, 64 sont adaptées à celles de la denture 51, 52 de la crémaillère 50 (même module et correspondance des diamètres primitifs ou lignes primitives) . La crémaillère présente en outre un profil 68 étage, coopérant avec un profil correspondant de guidage (non représenté) pratiqué dans le fond 20.Fig. 5A shows the actuating device 60 of the rack 50 and a support device or brake 70. The actuating device is guided by the middle part 10 through bores adjusted to the dimensions of the portions 66, 67 of the rod 61 and wearing this piece. The gear characteristics of the toothed pilot wheels 63, 64 are adapted to those of the toothing 51, 52 of the rack 50 (same module and correspondence of the pitch diameters or primitive lines). The rack also has a floor profile 68 cooperating with a corresponding guide profile (not shown) formed in the bottom 20.
Au moins un dispositif de frein 70 est prévu. Ce dispositif est constitué d'une plaquette 71, par exemple en verre, et — I _At least one brake device 70 is provided. This device consists of a plate 71, for example glass, and - I _
d'un ressort 72 disposé dans une creusure pratiquée dans le fond 20, de telle sorte qu'une force soit exercée par ledit ressort sur la crémaillère, par l'intermédiaire de la plaquette 71. Les fonctions de ce dispositif sont doubles: d'une part, empêcher toute rotation intempestive de la crémaillère, par exemple lors des mouvements de poignet, d'autre part, permettre une rotation aisée et continue par actionnement de la couronne 65. De préférence, on prévoira deux dispositifs, agencés de façon diamétralement opposées l'un de l'autre.a spring 72 disposed in a recess in the bottom 20, so that a force is exerted by said spring on the rack, through the plate 71. The functions of this device are double: d ' on the one hand, to prevent any untimely rotation of the rack, for example during wrist movements, on the other hand, to allow easy and continuous rotation by actuation of the ring gear 65. Preferably, provision will be made for two devices, arranged in a diametrically opposite manner one of the other.
Les fig. 5B et 5C montrent une variante d'exécution selon laquelle la crémaillère est formée de deux parties indépendantes 55, 56. La crémaillère extérieure 55 est actionnée par un dispositif 6OB dont la seule roue-pilote dentée 6OD est en prise avec la denture de la partie 55. La crémaillère intérieure 56 étant elle-même en prise avec la seule roue-pilote dentée 6OC du dispositif 6OA. L'ajustage des faces portant la référence globale 57 est tel qu'il n'y a pas de frottement entre les deux crémaillères, afin d'éviter que la rotation de l'une provoque une rotation inopinée de l'autre. Les autres caractéristiques sont semblables à celles du dispositif 60.Figs. 5B and 5C show an alternative embodiment in which the rack is formed of two independent parts 55, 56. The outer rack 55 is actuated by a device 6OB whose only toothed pilot wheel 6OD engages the teeth of the part 55. The inner rack 56 is itself engaged with the only toothed pilot wheel 6OC device 6OA. The adjustment of the faces bearing the overall reference 57 is such that there is no friction between the two racks, to prevent the rotation of one causing an unexpected rotation of the other. The other features are similar to those of device 60.
Les figures 6 et 7 illustrent une autre solution pour permettre la variation de la vitesse de rotation des plots. Pour entraîner les plots triangulaires 30 et cubiques 40 avec la même crémaillère 50, une denture conique est utilisée. Ainsi le satellite 34 de plus petit diamètre est placé sur la partie la plus haute de la crémaillère 50 alors le satellite 44, qui a le plus grand diamètre est placé sur la partie la plus basse. La figure 8 indique une possibilité avantageuse de placer la couronne 60 en prise direct avec une tige de plot 32, 42 pour entraîner un satellite 34, 44, ce qui provoque la rotation de la crémaillère 50 et des onze autres plots reliés à la crémaillère 50 par l'intermédiaire de leur satellites respectifs.Figures 6 and 7 illustrate another solution to allow the variation of the rotation speed of the pads. To drive the triangular 30 and cubic studs 40 with the same rack 50, a conical toothing is used. Thus the satellite 34 of smaller diameter is placed on the highest part of the rack 50 while the satellite 44, which has the largest diameter is placed on the lowest part. FIG. 8 indicates an advantageous possibility of placing the ring gear 60 in direct engagement with a pad rod 32, 42 to drive a satellite 34, 44, which causes the rack 50 and the other 11 pads connected to the rack 50 to rotate. through their respective satellites.
Comme le montre la figure 9, la montre, selon l'invention, comprend les éléments d'une montre bracelet habituelle. Le boîtier de cette montre n'est pas représenté. Il peut être imaginé d'une construction usuelle. Le cadran 3 est équipé de douze signes horaires 8 répartis sur son pourtour, présentant l'apparence de pierres. Des aiguilles des heures 4, des minutes 4A et des secondes 4B tournent au dessus du cadran 3. La paroi du boîtier est traversée par une tige de commande 9 portant une couronne 60. Cette tige 9 actionne un mécanisme de commande par le déplacement axial de la couronne 60 qui peut s'arrêter dans trois positions différentes.As shown in Figure 9, the watch according to the invention comprises the elements of a usual wristwatch. The case of this watch is not shown. It can be imagined from a usual construction. The dial 3 is equipped with twelve hourly signs 8 distributed around its periphery, presenting the appearance of stones. Needles 4 hours, minutes 4A and 4B seconds turn above the dial 3. The wall of the housing is traversed by a control rod 9 carrying a ring 60. This rod 9 actuates a control mechanism by the axial displacement of the ring 60 which can stop in three different positions.
A la figure 10 le cadran 3 a été enlevé, la tige 9 et la couronne de commande 60 sont placées dans leur position moyenne, de telle sorte que divers mécanismes logés sous le cadran sont visibles. En fait, les signes horaires 8 sont des décors portés par des plots 30, 40 de forme cylindrique ou prismatique, à face latérale bombée qui sont répartis autour du mouvement et peuvent tourner autour d'axes radiaux.In Figure 10 the dial 3 has been removed, the rod 9 and the control ring 60 are placed in their average position, so that various mechanisms housed under the dial are visible. In fact, the hourly signs 8 are decorations carried by studs 30, 40 of cylindrical or prismatic shape, with a curved side face which are distributed around the movement and can rotate about radial axes.
La fig. 13 montre que le mouvement 5 de la montre décrite est engagé .dans une cage circulaire formée de deux pièces: un cercle inférieur 80 et un cercle supérieur 81, et que les plots 30,40 sont montés sur une tige 32, 42 qui pivote par ses extrémités dans des gorges ménagées dans les cercles 80 et 81. Le plot 30, 40 orienté sur trois heures tourne sur la tige 9. Il est monté sur un manchon 82 tournant sur la tige 9. Ce manchon 82 est solidaire, comme les tiges 32, 42, d'un satellite 34, 44. Les axes 33, 43 des tiges 32, 42 situés sur 2/4/6/8/10 et 12 heures sont légèrement plus proches de la surface de la platine 73 que les axes des autres tiges, ces derniers étant à la même hauteur que l'axe de la tige de commande 9. Ces différences de hauteur entre les axes des satellites 34, 44 sont aussi visibles sur la figure 16. Une crémaillère circulaire 50 (fig. 13) est coaxiale au mouvement et placée sur la platine 73. Cette crémaillère 50 présente à sa périphérie une denture 51 dont les dents sont en saillie vers le bas et engrènent dans les satellites 34, 44. Les diamètres de ceux-ci seront naturellement ajustés de manière que leurs dentures engrènent pareillement dans la denture 51. Cette disposition permet de donner des spécifications adaptées aux différents plots 30, 40 et de les faire tourner à des vitesses, différentes, comme cela a été décrit dans le brevet CH 684 814.Fig. 13 shows that the movement 5 of the described watch is engaged in a circular cage formed of two parts: a lower circle 80 and an upper circle 81, and that the studs 30, 40 are mounted on a rod 32, 42 which pivots by its ends in gorges in the circles 80 and 81. The stud 30, 40 oriented on three hours rotates on the rod 9. It is mounted on a sleeve 82 rotating on the rod 9. This sleeve 82 is secured, like the rods 32, 42, of a satellite 34, 44. The pins 33, 43 of the rods 32, 42 situated on 2/4/6/8/10 and 12 hours are slightly closer to the surface of the plate 73 than the axes of the other rods, the latter being at the same height of the axis of the control rod 9. These differences in height between the axes of the satellites 34, 44 are also visible in Figure 16. A circular rack 50 (Figure 13) is coaxial with the movement and placed on the plate. 73. This rack 50 has at its periphery a toothing 51 whose teeth are projecting downwards and meshing in the satellites 34, 44. The diameters thereof will naturally be adjusted so that their teeth mesh similarly in the toothing 51 This provision makes it possible to give specifications adapted to the different 30, 40 and turn them at different speeds, as described in patent CH 684 814.
Sur son bord intérieur la crémaillère 50 présente une autre denture 18, à dents espacées, dirigées radialement . La roue à canon des heures 19 qui est un élément usuel du mouvement 5 porte lui une roue étoile à douze dents 38. Celles-ci coopèrent avec une roue d'encliquetage 21 logée dans une creusure circulaire de la platine 73. Cette roue 21 est découpée avec un bras élastique arqué 22 dont l'extrémité libre est accrochée entre deux tenons plantés dans le fond de la creusure. La roue d'encliquetage 21 porte encore un cliquet 23 pivotant sur un tenon solidaire de la planche de la roue 21. Le cliquet 23 est sollicité par un fil ressort 24 appuyé contre un deuxième tenon et sa rotation est limitée par un troisième tenon. La figure 10 comparée avec les figures 11 et 12 et indépendamment du mécanisme de commande qui sera expliqué plus loin, montre comment la roue d'encliquetage 21 fonctionne. Elle possède un doigt radialOn its inner edge the rack 50 has another toothing 18, spaced teeth, directed radially. The clock wheel of hours 19 which is a common element of the movement 5 carries it a star wheel with twelve teeth 38. These cooperate with a ratchet wheel 21 housed in a circular recess of the plate 73. This wheel 21 is cut with an arched elastic arm 22 whose free end is hung between two studs planted in the bottom of the hollow. The ratchet wheel 21 further carries a ratchet 23 pivoting on a tenon integral with the board of the wheel 21. The pawl 23 is biased by a spring wire 24 pressed against a second pin and its rotation is limited by a third pin. Figure 10 compared with Figures 11 and 12 and independently of the control mechanism which will be explained later, shows how the ratchet wheel 21 works. She has a radial finger
25 qui entre dans le chemin des dents triangulaires de la roue 38. A la figure 10 ce doigt va être libéré. Le bras élastique 22 est armé au maximum et agit sur la roue étoile 38. A la figure 11, le doigt du cliquet 23 accroche une dent de la denture 18 et fait avancer la crémaillère 50 jusqu'à ce que la pointe du sautoir 26 ait passé la dent contre laquelle ce sautoir appuie. Dès ce moment, c'est le sautoir25 which enters the path of the triangular teeth of the wheel 38. In Figure 10 this finger will be released. The elastic arm 22 is fully armed and acts on the star wheel 38. In FIG. 11, the pawl 23 hooks a tooth of the toothing 18 and advances the rack 50 until the point of the jumper 26 has past the tooth against which this saltire presses. From that moment, it's the jumper
26 qui amène la crémaillère 50 dans sa position finale. Ainsi à chaque heure la crémaillère 50 avance d'un angle égal à la somme des angles marqués, par des doubles flèches à la figure 11. Tous les plots 30, 40 tournent d'un angle déterminé, par les modules des dentures 51 et des satellites 34, 44. Comme les plots 30, 40 peuvent être des prismes ayant des nombres de faces différents et porter sur leurs faces des décors figurant des signes horaires 8 ayant différents aspects 35A, 45A, on obtient ainsi un tour d'heures dont l'apparence change chaque heure. En combinant les nombres de dents des dentures et les nombres de faces des plots, on peut réaliser des variations cycliques simples ou complexes.26 which brings the rack 50 into its final position. Thus, every hour the rack 50 advances by an angle equal to the sum of the marked angles, by double arrows in FIG. 11. All the studs 30, 40 rotate by a determined angle, by the modules of the teeth 51 and satellites 34, 44. Since the studs 30, 40 may be prisms having different faces numbers and bearing decorations on their faces showing hour signs 8 having different aspects 35A, 45A, a circle of hours is obtained, one of which appearance changes every hour. By combining the number of teeth of the teeth and the number of faces of the studs, simple or complex cyclic variations can be realized.
A la figure 10, un mécanisme de commande qui ajoute d'autres possibilités d'animations des plots est représenté en partie. Il comporte des pièces qui sont celles d'un mécanisme usuel. Ainsi la tige 9 agit sur une tirette 27 dont les positions sont fixées par un ressort de tirette 28.In Figure 10, a control mechanism that adds other possibilities of animations of the pads is shown in part. It includes parts that are those of a usual mechanism. Thus the rod 9 acts on a pull tab 27 whose positions are fixed by a pull-rod spring 28.
Un ensemble articulé coopère avec la tirette 27. Il est formé d'un levier basculant 29 et d'un levier coudé 74 dont l'extrémité libre incurvée peut s'engager devant le bec du cliquet 23 et le maintenir hors d'état d'actionner la denture 18 lors de la rotation alternative de la roue d' encliquetage 21. La figure 13 montre que le système articulé 29, 74 ,est placé dans une creusure du cadran 3.An articulated assembly cooperates with the pull tab 27. It is formed of a rocking lever 29 and an angled lever 74 whose curved free end can engage with the beak of the pawl 23 and keep it out of state. operate the tooth 18 during the alternative rotation of the ratchet wheel 21. FIG. 13 shows that the articulated system 29, 74 is placed in a recess of the dial 3.
La position du mécanisme représentée en traits pleins à la figure 10 est une position intermédiaire désignée par (B) . Cependant le passage de la couronne 60 en position enfoncée (A) et le passage en position externe (C) amènent tous deux le levier 74, du fait de la courbure de sa partie arrière fendue, dans la position représentée en traitillé à la figure 10. Le cliquet 23 peut actionner la crémaillère 50 lorsque la roue 21 revient à sa position désarmée, comme on l'a vu plus haut. En outre, dans une position du mécanisme, de préférence la position intermédiaire (B) un renvoi 75 comportant une étoile à trois becs à son niveau supérieur et une denture à son niveau inférieur est relié à la tige 9 de telle manière que la rotation de cette dernière déplace rapidement la crémaillère 50, ce qui permet d'ajuster à volonté une constellation particulière des différentes faces des plots 30, 40. Enfin la figure 12 montre comment le mécanisme se comporte lors d'une mise à l'heure. La roue des heures 19, 38 étant actionnée dans le sens antihoraire, le bec 25 de la roue 21 est déplacé vers la droite et arque le bras élastique 22 vers l'extérieur sans que le cliquet 23 n'agisse sur la crémaillère 50.The position of the mechanism shown in solid lines in FIG. 10 is an intermediate position designated by (B). However, the passage of the ring 60 in the depressed position (A) and the passage in the external position (C) both bring the lever 74, because of the curvature of its slotted rear portion, in the position shown in phantom in FIG. The pawl 23 can actuate the rack 50 when the wheel 21 returns to its disarmed position, as has been seen above. In addition, in a position of the mechanism, preferably the intermediate position (B) a reference 75 having a star with three nozzles at its upper level and a toothing at its lower level is connected to the rod 9 in such a way that the rotation of the latter quickly moves the rack 50, which allows to adjust at will a particular constellation of different faces of the pads 30, 40. Finally Figure 12 shows how the mechanism behaves during a time setting. The hour wheel 19, 38 being actuated counterclockwise, the spout 25 of the wheel 21 is moved to the right and arque the elastic arm 22 outwards without the pawl 23 acting on the rack 50.
Les cercles 80 et 81 sont fixés l'un à l'autre par des vis de cercle 76 et le cadran 3 est fixé par ses pieds 78 et des vis de cadran 78 à l'ensemble 80, 81 (figures 12, 14 et 15) . Comme il s'agit de fixer le cadran de manière qu'il assure les positions de divers organes fonctionnels, il est prévu quatre pieds 77 avec des vis de cadran 78 et quatre vis de cercle 76 pour la rigidité du cercle d'encageage. Dans la construction décrite précédemment, par le fait que la denture 51 de la crémaillère 50 est continue sur tout son pourtour, tous les plots 30, 40 sont actionnés à chaque heure lorsque le mécanisme se trouve dans la position activée, c'est-à-dire que la tige 9 se trouve en position enfoncée (A) . Toutefois il est possible de prévoir un autre fonctionnement. Ainsi la figure 16 montre une variante de réalisation de la denture de la crémaillère 50 avec plusieurs secteurs dentés 79 de courte longueur répartis en des emplacements A, A1, A" le long de la crémaillère. Chaque secteur 79 peut engrener aussi bien dans un satellite à neuf dents 34 que dans le satellite à 12 dents 44. Cet agencement permet de prévoir des variations diverses. Si par exemple la denture 51 ne comporte qu'un seul secteur denté dont la longueur couvre l'espace occupé par deux plots 30, 40 successifs, à chaque heure, un plot tournera de sa face exposée à la face adjacente, et le précédent de celle-ci à la suivante. Si les plots 40 ont quatre faces portant des signes successivement blancs, noirs, blancs, rouge, par exemple, durant douze heures de fonctionnement, chaque plot 40 deviendra successivement noir puis blanc, ce qui simulera le déplacement d'une aiguille des heures sur le cadran. Durant les douze heures suivantes, chaque plot deviendra rouge puis blanc, simulant également le déplacement d'une aiguille des heures mais de façon à indiquer les heures de nuit. Cet arrangement peut être équivalent à l'indication de l'heure dans un fuseau horaire différent de celui pour lequel l'aiguille des heures normale 4 (figure 9) est ajustée. Cette utilisation n'est qu'un exemple et que d'autres arrangements et d'autres utilisations peuvent être prévus avec les moyens décrits et sans pour autant sortir du cadre de l'invention. En particulier, le mouvement d'horlogerie pourrait ne pas être mécanique, mais à quartz, auquel sera couplé un module additionnel d'entraînement de la couronne et intégrant des moyens de commande spécifiques évidents pour l'homme du métier. The circles 80 and 81 are fixed to each other by circle screws 76 and the dial 3 is fixed by its feet 78 and dial screws 78 to the assembly 80, 81 (FIGS. 12, 14 and 15). ). As it is a question of fixing the dial so that it ensures the positions of various functional organs, four feet 77 are provided with dial screws 78 and four circle screws 76 for the rigidity of the casing ring. In the construction described above, in that the toothing 51 of the rack 50 is continuous all the way around, all the pads 30, 40 are actuated every hour when the mechanism is in the activated position, that is to say that is, the rod 9 is in the depressed position (A). However it is possible to provide another operation. Thus, FIG. 16 shows an alternative embodiment of the toothing of the rack 50 with a plurality of toothed sectors 79 of short length distributed at locations A, A 1 , A "along the rack, each sector 79 can mesh as well in a satellite with nine teeth 34 as in the satellite with 12 teeth 44. This arrangement makes it possible to provide various variations If, for example, the toothing 51 has only one tooth sector whose length covers the space occupied by two studs 30, 40 successive, every hour, a plot will turn from its exposed face to the adjacent face, and the precedent from it to the next If the pads 40 have four faces bearing successively white, black, white, red, by For example, during twelve hours of operation, each stud 40 will successively become black and then white, which will simulate the movement of an hour hand on the dial.For the next twelve hours, each pad will become red or black. is white, also simulating the movement of an hour hand but so as to indicate the hours of night. This arrangement may be equivalent to indicating the time in a time zone different from that for which the normal hour hand 4 (Figure 9) is adjusted. This use is only an example and that other arrangements and other uses can be provided with the means described and without departing from the scope of the invention. In particular, the watch movement might not be mechanical, but quartz, which will be coupled an additional drive module of the crown and incorporating specific control means obvious to the skilled person.
