Description
MONTRE DU TYPE COMPORTANT UNE COURONNE POUR LA MANOEUVRE D'UNE LUNETTE TOURNANTE INDICATRICE DITE « REHAUT » La présente invention concerne une montre du type comportant une première couronne principale, en liaison avec un mécanisme d'entrainement des différentes fonctions de la montre, et une seconde couronne auxiliaire destinée à une fonction supplémentaire consistant à commander une lunette indicatrice tournante, dite « rehaut », disposée à l'intérieur de la montre, entre sa glace et la périphérie de son cadran, et manoeuvrable par ladite seconde couronne, par l'intermédiaire d'un pignon de commande en prise avec le rehaut, lui-même relié à un tube taraudé traversant librement un tube fixe vissé dans le boitier de la montre, et associé à des moyens d'indexation du rehaut. The present invention relates to a watch of the type comprising a first main ring, in connection with a drive mechanism of the different functions of the watch, and a ring gear of the type comprising a first main ring, in connection with a drive mechanism of the different functions of the watch, and a second auxiliary crown intended for an additional function of controlling a rotating indicating bezel, called "flange", disposed inside the watch, between its mirror and the periphery of its dial, and operable by said second ring, by the intermediate of a control pinion in engagement with the flange, itself connected to a threaded tube freely passing through a fixed tube screwed into the case of the watch, and associated with indexing means of the flange.
Une telle lunette indicatrice, ou rehaut, est par exemple destinée à afficher un fuseau horaire, par simple rotation par rapport au boitier fixe qui comporte les indications nécessaires, en l'occurrence le nom des villes. Such an indicator telescope, or flange, is for example intended to display a time zone, by simple rotation relative to the fixed housing which includes the necessary indications, in this case the names of cities.
Lorsque cette fonction est associée à la couronne principale de la montre, il est nécessaire d'exercer un tirage supplémentaire sur la couronne, ce qui peut provoquer le déréglage des autres fonctions en cas d'erreur de positions. Il a été recherché de remédier à cela, mais également de définir des moyens d'indexation du rehaut de réalisation simple et économique par rapport à l'art antérieur. Celui-ci enseigne par exemple d'indexer le rehaut selon les fuseaux horaires, en disposant trois cliquets fixes sur le boitier, aptes à coopérer avec vingt-quatre évidements du rehaut. Mais cet agencement est encombrant et provoque des contraintes mécaniques sur le rehaut. When this function is associated with the main crown of the watch, it is necessary to exert an additional draw on the crown, which may cause the adjustment of other functions in case of position error. It has been sought to remedy this, but also to define means for indexing the flange simple and economical realization compared to the prior art. This one teaches for example to index the flange according to the time zones, by arranging three pawls fixed on the case, able to cooperate with twenty-four recesses of the flange. But this arrangement is bulky and causes mechanical stress on the flange.
Un autre dispositif d'indexation connu consiste à disposer trois billes dans trois logements radiaux d'un axe, celui-ci traversant une douille ayant une gorge périphérique percée par trois trous correspondant aux billes, ladite gorge recevant un ressort spiral agissant en contrainte élastique sur les billes. La présence du ressort spiral et l'usinage nécessaire aux six logements et à la gorge pénalisent notablement le système. La présente invention a pour but de remédier à l'ensemble de ces inconvénients et concerne à cet effet une montre du type comportant une première couronne principale, en liaison avec un mécanisme d'entrainement des différentes fonctions de la montre, et une seconde couronne auxiliaire destinée à une fonction supplémentaire consistant à commander une lunette indicatrice tournante, dite « rehaut », disposée à l'intérieur de la montre, entre sa glace et la périphérie de son cadran, et manoeuvrable par ladite seconde couronne, par l'intermédiaire d'un pignon de commande en prise avec le rehaut, lui-même relié à un tube taraudé traversant librement un tube fixe vissé dans le boitier de la montre, et associé à des moyens d'indexation du rehaut, caractérisée en ce que les moyens d'indexation du rehaut sont constitués par une bague d'indexation, solidaire de la couronne et traversée librement par un tube d'indexation, éléments entre lesquels est interposée au moins une lame élastiquement déformable disposée dans la bague, de façon tangentielle au tube et susceptible de venir en appui sur au moins un méplat du tube, correspondant à l'une des positions souhaitées du rehaut. La présente invention concerne également les 15 caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles. 20 Cette description donnée à titre d'exemple non limitatif, fera mieux comprendre comment l'invention peut être réalisée en référence aux dessins annexés sur lesquels : 25 La figure 1 représente une vue en plan d'une montre et de son rehaut selon l'invention. La figure 2 est une vue en coupe selon la ligne AA de la figure 1. 30 La figure 3 est une vue à échelle agrandie du détail B selon la coupe AA de la figure 2. Another known indexing device consists in arranging three balls in three radial housings of an axis, the latter passing through a sleeve having a peripheral groove pierced by three holes corresponding to the balls, said groove receiving a spiral spring acting in elastic stress on the marbles. The presence of the spiral spring and the necessary machining of the six housings and the throat penalize the system significantly. The present invention aims to remedy all of these disadvantages and concerns for this purpose a watch of the type comprising a first main ring, in connection with a drive mechanism of the various functions of the watch, and a second auxiliary ring intended for an additional function of controlling a rotating indicating bezel, called "flange", arranged inside the watch, between its mirror and the periphery of its dial, and operable by said second ring, via a control pinion in engagement with the flange, itself connected to a threaded tube freely passing through a fixed tube screwed into the case of the watch, and associated with indexing means of the flange, characterized in that the means of indexing the flange are constituted by an indexing ring, secured to the crown and freely traversed by an indexing tube, elements between which is interposed with less an elastically deformable blade disposed in the ring, tangentially to the tube and capable of bearing on at least one flat part of the tube, corresponding to one of the desired positions of the flange. The present invention also relates to the features which will become apparent in the course of the following description, and which will have to be considered in isolation or in all their possible technical combinations. This description, given by way of nonlimiting example, will make it easier to understand how the invention can be made with reference to the appended drawings in which: FIG. 1 represents a plan view of a watch and its flange according to FIG. invention. FIG. 2 is a sectional view along line AA of FIG. 1. FIG. 3 is an enlarged view of detail B in section AA of FIG.
La figure 4 est une vue en coupe selon la ligne CC de la figure 3. Figure 4 is a sectional view along the line CC of Figure 3.
La figure 5 est une vue en coupe selon la ligne DD de la figure 3. La figure 6 est une vue en coupe selon la ligne EE de la figure 3. FIG. 5 is a sectional view along line DD of FIG. 3. FIG. 6 is a sectional view along the line EE of FIG. 3.
La montre 1 globalement désignée sur la figure 1 comporte une première couronne principale 2, en liaison avec un mécanisme d'entrainement des différentes fonctions de la montre 1, et une seconde couronne auxiliaire 3 destinée à une fonction supplémentaire consistant à commander une lunette indicatrice tournante, dite « rehaut » 4, disposée à l'intérieur de la montre 1, entre sa glace 5 et la périphérie de son cadran 6, et manoeuvrable par ladite seconde couronne 3, par l'intermédiaire d'un pignon de commande 7 en prise avec le rehaut 4, lui-même relié à un tube taraudé 8 traversant librement un tube fixe 9 vissé dans le boitier 10 de la montre 1, et associé à des moyens d'indexation du rehaut 4. The watch 1 generally designated in FIG. 1 comprises a first main crown 2, in connection with a drive mechanism of the different functions of the watch 1, and a second auxiliary ring gear 3 intended for an additional function of controlling a rotating indicator bezel , said "flange" 4, disposed inside the watch 1, between its mirror 5 and the periphery of its dial 6, and operable by said second ring 3, via a control gear 7 in mesh with the flange 4, itself connected to a threaded tube 8 freely passing through a fixed tube 9 screwed into the housing 10 of the watch 1, and associated with indexing means of the flange 4.
Selon l'invention, les moyens d'indexation du rehaut 4 sont constitués par une bague d'indexation 11, solidaire de la couronne 2 et traversée librement par un tube d'indexation 12, éléments 11,12 entre lesquels est interposée au moins une lame 13 élastiquement déformable disposée dans la bague 11, de façon tangentielle au tube 12 et susceptible de venir en appui sur au moins un méplat 14 du tube 12, correspondant à l'une des positions souhaitées du rehaut 4. According to the invention, the indexing means of the flange 4 are constituted by an indexing ring 11, secured to the ring 2 and freely traversed by an indexing tube 12, elements 11, 12 between which is interposed at least one 13 elastically deformable blade disposed in the ring 11, tangentially to the tube 12 and capable of bearing on at least one flat portion 14 of the tube 12, corresponding to one of the desired positions of the flange 4.
Selon le présent exemple de réalisation, et préférentiellement, l'indexation du rehaut 4 s'effectue par l'intermédiaire de trois lames 13, disposées dans une chambre cylindrique 15 de la bague 11, en définissant entre elles des angles a de 60°, pour former un triangle équilatéral dans lequel s'inscrit le tube (12) comportant trois méplats 14 correspondants. Dans ce cas, le rapport d'engrenage pignon denture du rehaut est tel que : 1/3 de tour de couronne 3 = 1/24 de tour de rehaut 4 1 tour = 3/3 de tour de couronne 3 = 3/24 de rehaut 4 8 tours = 8 x 3/3 de couronne 3 = 24/24 de rehaut 4 = 24 fuseaux horaires Bien entendu, d'autres rapports peuvent être envisagés. According to the present embodiment, and preferably, the indexing of the flange 4 is effected by means of three blades 13, arranged in a cylindrical chamber 15 of the ring 11, defining between them angles of 60 °, to form an equilateral triangle in which fits the tube (12) having three flats 14 corresponding. In this case, the sprocket gear ratio of the flange is such that: 1/3 turn of crown 3 = 1/24 turn of flange 4 1 turn = 3/3 turn of crown 3 = 3/24 of flare 4 8 turns = 8 x 3/3 crown 3 = 24/24 flare 4 = 24 time zones Of course, other reports may be considered.
Comme le montre bien la figure 3, le pignon 7 est relié solidairement au tube taraudé 8, par l'intermédiaire d'une vis axiale 17, lui-même en prise avec la couronne 2 sur l'extrémité filetée d'un axe central 18 de celle-ci. As shown in FIG. 3, the pinion 7 is integrally connected to the threaded tube 8, by means of an axial screw 17, itself engaged with the ring 2 on the threaded end of a central axis 18 of it.
La bague d'indexation 11 est solidaire d'un logement interne cylindrique 19 de la couronne 3 et susceptible d'être entrainée en rotation autour du tube d'indexation 12, qui lui, est rendu solidaire du tube fixe 9 de traversée du boitier 10, par l'intermédiaire de contours hexagonaux 20,21 réalisés en correspondance sur les deux éléments 9,12. La bague d'indexation 11 est chassée et collée 10 dans le logement cylindrique 19 de la couronne par l'intermédiaire d'au moins un joint torique 22 et d'une rondelle de retenue 23 de celui-ci. The indexing ring 11 is integral with a cylindrical internal housing 19 of the ring gear 3 and capable of being driven in rotation around the indexing tube 12, which is secured to the fixed tube 9 through which the box 10 passes. by means of hexagonal contours 20,21 made in correspondence on the two elements 9,12. The indexing ring 11 is driven out and adhered to the cylindrical housing 19 of the ring gear via at least one O-ring 22 and a retaining washer 23 thereof.
