Description

La présente invention est relative à une boîte de montre comportant une carrure, un fond, un mouvement logé dans la boite, un cadran surmontant le mouvement et un ensemble pouvant être entraîné rotativement par rapport à la carrure et au cadran, ledit ensemble comportant une lunette présentant un épaulement annulaire intérieur, une glace assujettie à la lunette par l'intermédiaire d'une première garniture et un organe annulaire formant réhaut, une seconde garniture étant interposée entre la lunette et la carrure.The present invention relates to a watch case comprising a middle part, a case back, a movement housed in the box, a dial surmounting the movement and an assembly that can be rotated with respect to the middle and to the dial, said assembly comprising a bezel. having an inner annular shoulder, a crystal fixed to the bezel by means of a first lining and an annular member forming a flange, a second lining being interposed between the bezel and the middle part.

Une boite de montre correspondant dans les grandes lignes à la définition générique qui vient d'être donnée est décrite dans le document CH-A-432 388 (Schmitz Frères). Dans cette construction un anneau intérieur est vissé dans la carrure et cet anneau comporte une collerette qui repose sur un épaulement de la lunette de façon à maintenir en place cette lunette sur la carrure. L'anneau n'est utilisé ici que pour retenir l'ensemble mobile sur la carrure et n'a pas d'autres fonctions. De ce fait, l'emboîtage du mouvement ne peut se faire que par le dessous de la carrure avec, comme corollaire, un cadran dont le diamètre est plus petit que le diamètre hors-tout du mouvement. Dans le cas où le réhaut de la lunette porte des graduations tournant en regard d'autres graduations portées par le cadran fixe, ces graduations étant utilisées comme règle à calcul par exemple, on a intérêt à agrandir le cadran au-delà du diamètre du mouvement pour augmenter la précision de lecture et faciliter l'application des graduations sur le cadran et le réhaut.A watch case corresponding broadly to the generic definition which has just been given is described in document CH-A-432 388 (Schmitz Frères). In this construction an inner ring is screwed into the middle part and this ring comprises a collar which rests on a shoulder of the bezel so as to hold this bezel in place on the middle part. The ring is used here only to retain the mobile assembly on the middle part and has no other functions. Therefore, the movement can only be fitted from below the middle with, as a corollary, a dial whose diameter is smaller than the overall diameter of the movement. In the case where the bezel flange carries graduations rotating opposite other graduations carried by the fixed dial, these graduations being used as slide rule for example, it is advantageous to enlarge the dial beyond the diameter of the movement to increase reading accuracy and facilitate the application of graduations on the dial and the flange.

Ainsi, comme on le verra dans la présente invention, si l'on utilise l'anneau du document cité, non seulement comme moyen de retenue, mais encore comme cercle d'encageage pour le mouvement, il est possible de proposer une construction dans laquelle le cadran est plus grand que le mouvement. L'anneau remplit alors une fonction supplémentaire qui n'est ni décrite ni suggérée dans le document cité. Pour atteindre ce but, la boite de l'invention est caractérisée par le fait qu'elle comprend un cercle d'encageage disposé à l'intérieur de la carrure, des premiers moyens pour fixer le mouvement dans le cercle d'encageage et des seconds moyens pour solidariser le cercle à la carrure, ledit cercle présentant une collerette annulaire reposant sur ledit épaulement pour accrocher ledit ensemble sur ladite carrure.Thus, as will be seen in the present invention, if the ring of the cited document is used, not only as a retaining means, but also as a casing ring for the movement, it is possible to propose a construction in which the dial is larger than the movement. The ring then fulfills an additional function which is neither described nor suggested in the cited document. To achieve this object, the box of the invention is characterized in that it comprises a casing circle disposed inside the middle, first means for fixing the movement in the casing circle and second means for securing the circle to the middle part, said circle having an annular collar resting on said shoulder for hanging said assembly on said middle part.

L'invention sera expliquée maintenant à l'aide de la description qui suit donnée à titre d'exemple et en s'aidant du dessin qui l'illustre et dans lequel

  • - la figure 1 est une vue en plan de la boite de montre selon l'invention;
  • - la figure 2 est une coupe selon la ligne II-II de la figure 1;
  • - la figure 3 montre une variante d'exécution par rapport à celle représentée en figure 2 où la boite de montre est pourvue d'une lunette à rotation unidirectionnelle;
  • - la figure 4 est une coupe selon la ligne IV-IV de la figure 1;
  • - la figure 5 montre une variante d'exécution par rapport à celle représentée en figure 4; et
  • - la figure 6 montre une variante d'exécution par rapport à celle de la figure 2.
The invention will now be explained with the aid of the following description given by way of example and with the aid of the drawing which illustrates it and in which
  • - Figure 1 is a plan view of the watch case according to the invention;
  • - Figure 2 is a section along line II-II of Figure 1;
  • - Figure 3 shows an alternative embodiment to that shown in Figure 2 where the watch case is provided with a bezel with unidirectional rotation;
  • - Figure 4 is a section along the line IV-IV of Figure 1;
  • - Figure 5 shows an alternative embodiment to that shown in Figure 4; and
  • - Figure 6 shows an alternative embodiment compared to that of Figure 2.

La figure 1 est une vue de dessus de la boite de montre selon l'invention. Sur le cadran 6 sont montées par exemple les aiguilles 43. A la carrure sont assujetties des cornes pour attacher les brins 41 et 42 d'un bracelet. On distingue sur cette vue en plan une lunette tournante 1 munie d'un moletage 19. Solidaire de la lunette 1, se trouve un réhaut 5 sur lequel sont apposées des graduations 45. En regard de ces dernières se trouvent d'autres graduations 46 apposées sur le cadran 6. Les graduations 45 et 46 ne sont représentées ici qu'en partie.Figure 1 is a top view of the watch case according to the invention. On the dial 6 are mounted, for example, the needles 43. Horns are attached to the middle to attach the strands 41 and 42 of a bracelet. We can see in this plan view a rotating bezel 1 provided with a knurling 19. Solid with the bezel 1, is a flange 5 on which are affixed graduations 45. Next to these are other graduations 46 affixed on dial 6. The graduations 45 and 46 are only partially represented here.

Les coupes des figures 2 et 4, réalisées respectivement selon les lignes II-II et IV-IV de la figure 1, montrent que la boite comporte une carrure 8, un fond 13, un mouvement 7 logé dans la boite, un cadran 6 surmontant le mouvement 7. Un ensemble 3 comportant une lunette 1 présentant un épaulement annulaire intérieur 20, une glace 2 assujettie à la lunette par l'intermédiaire d'une première garniture 4 et un organe annulaire formant réhaut 5, peut être entraîné en rotation par rapport à la carrure et au cadran. Entre la lunette et la carrure est pincée une seconde garniture 9 qui assure l'étanchéité de la boite.The sections of Figures 2 and 4, made respectively along lines II-II and IV-IV of Figure 1, show that the box has a middle part 8, a bottom 13, a movement 7 housed in the box, a dial 6 surmounting the movement 7. An assembly 3 comprising a bezel 1 having an inner annular shoulder 20, a lens 2 secured to the bezel by means of a first lining 4 and an annular member forming a flange 5, can be driven in rotation relative to the middle and the dial. Between the bezel and the middle part is pinched a second lining 9 which seals the case.

Dans l'exemple montré aux figures, la garniture 9 est disposée entre deux surfaces cylindriques coaxiales limitant l'une 22 une portion de la lunette et l'autre 23 une portion de la carrure.In the example shown in the figures, the lining 9 is arranged between two coaxial cylindrical surfaces, one limiting 22 a portion of the bezel and the other 23 a portion of the middle part.

Les figures 2 et 4 montrent surtout ce qui fait la particularité de la présente invention, à savoir que la boite comporte un cercle d'encageage 10 - 11 dispose à l'intérieur de la carrure 8, ce cercle présentant une collerette annulaire 21 reposant sur l'épaulement 20 de la lunette 1 pour accrocher ou retenir l'ensemble tournant 3 sur la carrure 8. Ainsi, l'anneau du document cite est transformé ici en cercle d'encageage qui sert non seulement de retenue à la lunette mais encore de support au mouvement. La figure 4 montre aussi que des premiers moyens sont prévus pour fixer le mouvement 7 dans le cercle 10 - 11 ces moyens consistant en des brides 16 et des vis 17 dans la construction prise ici en exemple. La figure 2 montre aussi que des seconds moyens 31 sont mis en oeuvre pour solidariser le cercle 10 - 11 à la carrure 8.Figures 2 and 4 show above all what makes the particularity of the present invention, namely that the box has a casing ring 10 - 11 has inside the middle part 8, this circle having an annular flange 21 resting on the shoulder 20 of the bezel 1 for hooking or retaining the rotating assembly 3 on the middle part 8. Thus, the ring of the cited document is transformed here into a casing circle which not only serves to retain the bezel but also to support for movement. Figure 4 also shows that first means are provided for fixing the movement 7 in the circle 10 - 11 these means consisting of flanges 16 and screws 17 in the construction taken here as an example. FIG. 2 also shows that second means 31 are used to secure the circle 10-11 to the middle part 8.

La figure 2 montre que la carrure 8 présente dans sa partie inférieure une collerette 24 s'étendant vers le centre de la boite. Sur cette collerette 24 s'appuie le cercle d'encageage 10, 11. Les seconds moyens évoqués plus haut sont des vis 31 placées verticalement et traversant des forures 25 pratiquées dans la collerette 24 et vissées dans des taraudages 26 pratiquées dans le cercle 11.Figure 2 shows that the middle part 8 has in its lower part a flange 24 extending towards the center of the box. On this collar 24 is supported by the casing ring 10, 11. The second means mentioned above are screws 31 placed vertically and passing through holes 25 made in the flange 24 and screwed into threads 26 made in the circle 11.

Il est intéressant de noter ici que la construction prévoit un fond 13 muni de saillies 27 qui, une fois le fond en place sous la carrure 8, empêchent les vis 31 de se dévisser, même si ces vis se sont débloquées. Ici le fond 13 est vissé en 14 à la carrure 8. Il pourrait aussi y être fixé à cran.It is interesting to note here that the construction provides a bottom 13 provided with projections 27 which, once the bottom in place under the middle part 8, prevent the screws 31 from being unscrewed, even if these screws have been released. Here the bottom 13 is screwed at 14 to the middle part 8. It could also be fixed there.

Les figures 2 et 4, comme la figure 5 dont il sera question plus bas, font apparaître un cadran 6 dont le diamètre est plus grand que le diamètre hors-tout du mouvement 7 ce qui est favorable pour les raisons évoquées dans le préambule de cette description. Dans ce cas les mêmes figures montrent que le mouvement 7 est emboîté par le dessus du cercle d'encageage 11, ce cercle présentant un épaulement 50 contre lequel est appuyé un filet 51 du mouvement 7. Pour permettre ce dépassement du cadran, les figures 2 et 4 montrent que le cercle d'encageage est réalisé en deux parties, soit une première partie intérieure 11 comportant l'épaulement 50 contre lequel est appuyé le mouvement 7 et une seconde partie extérieure 10 comportant la collerette 21. Le plus grand diamètre possible du cadran 6 est limité par le diamètre intérieur du cercle 10. On observera par ailleurs que le réhaut 5 peut aussi chevaucher le cadran 6 dans le but de rendre invisible la fente se trouvant entre le réhaut et le cadran et dans le but également de simplifier la construction.Figures 2 and 4, like Figure 5 which will be discussed below, show a dial 6 whose diameter is larger than the overall diameter of the movement 7 which is favorable for the reasons mentioned in the preamble of this description. In this case the same figures show that the movement 7 is fitted by the top of the casing circle 11, this circle having a shoulder 50 against which is supported a thread 51 of the movement 7. To allow this overshoot of the dial, Figures 2 and 4 show that the casing circle is produced in two parts, namely a first internal part 11 comprising the shoulder 50 against which the movement 7 is pressed and a second external part 10 comprising the flange 21. The largest possible diameter of the dial 6 is limited by the inside diameter of the circle 10. It will also be observed that the flange 5 can also overlap the dial 6 in order to make the slot between the flange and the dial invisible and also in order to simplify the construction.

Le montage de la boite avec le mouvement qu'elle emprisonne se fait selon l'ordre suivant. Par le haut de la lunette 1, prise seule, on monte la partie extérieure 10 du cercle d'encageage jusqu'à ce que la collerette 21 du cercle vienne en appui sur l'épaulement 20 de la lunette. On monte le réhaut 5 dans la lunette 1 et on pose la garniture 4 sur le réhaut. On force la glace 2 dans la garniture 4. On obtient l'ensemble 3 destiné à tourner sur la carrure 8, cet ensemble portant de surcroît la partie extérieure 10 du cercle d'encageage, cette partie restant libre de se mouvoir en rotation sur cet ensemble. On introduit par le dessus le mouvement 7 dans la partie intérieure 11 du cercle d'en- cageage jusqu'à ce que le filet 51 du mouvement 7 vienne buter sur l'épaulement 50 du cercle. On fixe le mouvement 7 sur le cercle 11 au moyen des vis 17. On introduit la partie intérieure 11 du cercle, avec son mouvement, à l'intérieur de la partie extérieure 10 du cercle et par le dessous de cette partie extérieure. On fixe ces deux parties du cercle l'une sur l'autre par des moyens qui seront discutés plus bas. On dispose une garniture 9 sur la surface cylindrique 22 de la lunette 1. L'ensemble ainsi formé est introduit par le dessus de la carrure 8 jusqu'à appui du cercle 11 contre la collerette 24 de la carrure. Le cercle 11 est fixé à la carrure au moyen des vis 31. Enfin, on ferme la boite au moyen du fond vissé 13 en interposant une garniture 15 entre fond et carrure.The assembly of the box with the movement it traps is done in the following order. From the top of the bezel 1, taken alone, the outer part 10 of the casing circle is mounted until the flange 21 of the circle comes to bear on the shoulder 20 of the bezel. Mount the flange 5 in the bezel 1 and place the trim 4 on the flange. The glass 2 is forced into the lining 4. The assembly 3 is obtained intended to rotate on the middle part 8, this assembly additionally carrying the outer part 10 of the casing circle, this part remaining free to move in rotation on this together. The movement 7 is introduced from above into the inner part 11 of the casing circle until the thread 51 of the movement 7 abuts on the shoulder 50 of the circle. The movement 7 is fixed on the circle 11 by means of the screws 17. The internal part 11 of the circle is introduced, with its movement, inside the external part 10 of the circle and from below this external part. These two parts of the circle are fixed to each other by means which will be discussed below. There is a lining 9 on the cylindrical surface 22 of the bezel 1. The assembly thus formed is introduced through the top of the middle part 8 until the hoop 11 presses against the flange 24 of the middle part. The circle 11 is fixed to the middle by means of the screws 31. Finally, the box is closed by means of the screwed bottom 13 by interposing a lining 15 between the bottom and the middle.

Il a été question au paragraphe précédent de la fixation des deux parties du cercle d'encageage l'un dans l'autre. Un mode de réalisation est montré à la figure 4 où l'on voit que la partie extérieure 10 est fixée sur la partie intérieure 11 au moyen de vis 12. Dans cette construction, on s'arrange en outre pour que les têtes de vis 12 se trouvent situées à faible distance de la paroi interne 52 de la carrure 8 quand la boite est montée. On comprendra que par ce moyen, les vis sont imperdables car, sitôt débloquées, les têtes viennent en contact avec la carrure ce qui empêche les vis de se dévisser plus avant.The previous paragraph discussed the fixing of the two parts of the casing circle one inside the other. An embodiment is shown in Figure 4 where we see that the outer part 10 is fixed on the inner part 11 by means of screws 12. In this construction, it is further arranged so that the screw heads 12 are located a short distance from the inner wall 52 of the middle part 8 when the box is mounted. It will be understood that by this means, the screws are captive because, as soon as unlocked, the heads come into contact with the middle which prevents the screws from unscrewing further.

Un autre mode de fixation des deux parties du cercle d'encageage est montré en figure 5. Ici la partie extérieure 30 présente des zones élastiques 53 munies chacune d'un bec 54 qui vient s'accrocher dans une échancrure 55 pratiquée dans la partie intérieure 11. Dans cette exécution, la partie extérieure 30 sera avantageusement réalisée en matière plastique.Another method of fixing the two parts of the casing circle is shown in FIG. 5. Here the external part 30 has elastic zones 53 each provided with a spout 54 which comes to hang in a notch 55 formed in the internal part 11. In this embodiment, the outer part 30 will advantageously be made of plastic.

La présente invention permet également, si cela est nécessaire, d'utiliser un mouvement dont le cadran est plus petit ou égal en diamètre au diamètre du mouvement. Ce mode d'exécution est montré en figure 6. Dans ce cas le mouvement 7 est emboîté par le dessous d'un cercle d'encagea- ge 40 qui peut être réalisé d'une seule pièce avec sa collerette 21 et un épaulement 28 contre lequel est appuyé un filet 29 du mouvement.The present invention also allows, if necessary, to use a movement whose dial is smaller or equal in diameter to the diameter of the movement. This embodiment is shown in Figure 6. In this case the movement 7 is fitted from below a casing circle 40 which can be made in one piece with its flange 21 and a shoulder 28 against which is supported a net 29 of the movement.

La figure 3 montre un mode d'exécution de la lunette tournante dans lequel est monté, entre l'ensemble rotatif 3, par ailleurs conforme à la description ci-dessus, et la carrure 37 un dispositif de rotation unidirectionnel dudit ensemble. Ce dispositif comporte un anneau 33 dans lequel sont levés des ressorts qui agissent sur des crans 34 dits crémaillère et apposés sur la lunette 38. Cet anneau 33 est retenu et orienté par au moins un ergot 35 emprisonné dans le logement 36 pratiqué dans la carrure 37. Un exemple détaillé de cette construction est décrit dans le document CH-A-631 592. Le dispositif est avantageusement placé à l'extérieur du périmètre de la garniture 9.
