Abstract

A brace (flange) (8) has an annular central part (8a) bearing on the glass (5) and diametrical arms (8b) fixed to the lugs (3b) of the case serving for the attachment of a bracelet. Thus, the glass is held in position even when it is engaged only with slight friction in a sealing packing (6) accommodated in the case body (3). The glass (5) will be dismantled easily by engaging a blade in a blade groove (16) of the case body (3) and in an annular groove (17) in the edge section of the glass (5). <IMAGE>

Description

La présente invention a pour objet une boîte de montre du type dit "monocoque", c'est-à-­dire dont le fond et la carrure sont en une pièce.The subject of the present invention is a watch case of the so-called "monocoque" type, that is to say the case and the middle of which are in one piece.

De telles boîtes de montres, connues en soi, présentent l'inconvénient que, si la glace est montée à cran sur le corps de boîte ou fond-­carrure, le démontage n'est pas aisé car il est im­possible d'agir sous la glace pour exercer sur elle une pression tendant à l'extraire.Such watch cases, known per se, have the disadvantage that, if the glass is mounted on the notch on the body of the case or case-back, disassembly is not easy because it is impossible to act under the glass to exert on it a pressure tending to extract it.

Dans le cas de glaces-calottes, en verre artificiel, déformable élastiquement, il est possi­ble d'utiliser des appareils enserrant la glace et la déformant pour permettre de l'extraire. Une telle solution n'est cependant pas possible avec les glaces en matière extra-dure telles que verre minéral trem­pé ou saphir qui sont pratiquement indéformables.In the case of ice-caps, made of artificial glass, elastically deformable, it is possible to use devices enclosing the ice and deforming it to allow it to be extracted. Such a solution is however not possible with the glass in extra hard material such as tempered mineral glass or sapphire which are practically non-deformable.

Le but de la présente invention est de fournir un moyen de fixation d'une glace de boîte de montre monocoque qui permette un démontage aisé de la glace tout en assurant une fixation fiable de celle-ci.The object of the present invention is to provide a means of fixing a monocoque watch case glass which allows easy dismantling of the glass while ensuring reliable fixing thereof.

Ce but est atteint grâce aux moyens dé­finis dans la revendication 1.This object is achieved by the means defined in claim 1.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.

  • La fig. 1 est une vue en plan d'une montre-bracelet.
  • La fig. 2 en est une vue en élévation.
  • La fig. 3 est une coupe partielle sui­vant la ligne III-III de la fig. 1, à échelle agrandie.
  • La fig. 4 est une coupe suivant la ligne IV-IV de la fig. 1, à l'échelle de la fig. 3, et
  • La fig. 5 est une vue en plan d'un détail, avec coupe partielle, à l'échelle des figs. 3 et 4.
The drawing represents, by way of example, an embodiment of the subject of the invention.
  • Fig. 1 is a plan view of a wristwatch.
  • Fig. 2 is an elevational view thereof.
  • Fig. 3 is a partial section along line III-III of FIG. 1, on an enlarged scale.
  • Fig. 4 is a section along the line IV-IV of FIG. 1, on the scale of FIG. 3, and
  • Fig. 5 is a plan view of a detail, with partial section, on the scale of FIGS. 3 and 4.

Le mouvement de la montre-bracelet repré­senté, désigné par 1, muni de son cadran désigné par 2, est logé dans une boîte étanche du type monocoque, c'est-à-dire dont le corps ou la carrure, désigné par 3, est venu d'une pièce avec le fond désigné par 3a. Le mouvement est fixé à ce fond-carrure 3 par des vis 4 prenant dans celui-ci.The movement of the wristwatch represented, designated by 1, provided with its dial designated by 2, is housed in a watertight box of the monocoque type, that is to say whose body or caseband, designated by 3, is come from a room with the bottom designated by 3 a . The movement is fixed to this case-back 3 by screws 4 taking in it.

La glace de la boîte, de préférence en matière extra-dure telle que du verre minéral trempé ou du saphir, désignée par 5, est engagée à frotte­ment doux dans le corps de boîte ou carrure 3 avec interposition d'une garniture d'étanchéité 6 en ma­tière souple et compressible. Cette glace est en ap­pui sur une bague 7 entourant le mouvement et qui joue le rôle de rehaut.The crystal of the case, preferably made of extra hard material such as tempered mineral glass or sapphire, designated by 5, is engaged with gentle friction in the case body or middle part 3 with the interposition of a seal 6 made of flexible and compressible material. This glass is supported on a ring 7 surrounding the movement and which plays the role of flange.

La glace 5 est maintenue en place dans le fond-carrure et méme appliquée axialement contre la tranche du rehaut 7 par une bride diamétrale de tension 8 comprenant une partie annulaire 8a prenant appui sur elle et deux paires de bras 8b, diamétra­lement opposées, dont les extrémités viennent s'en­gager de part et d autre de chacun de deux gonds 3b que présente la carrure 3 et qui servent à la fixa­tion du bracelet désigné par 9.The crystal 5 is held in place in the backband and even applied axially against the edge of the flange 7 by a diametrical flange of tension 8 comprising an annular part 8 a resting on it and two pairs of arms 8 b , diametrically opposite, the ends of which come to engage on either side of each of two hinges 3 b which has the middle part 3 and which serve when attaching the bracelet designated by 9.

L'assemblage entre les extrémités des bras 8b et chacun des gonds 3b est obtenu grâce à une barrette 10 à étages dont la partie terminale, la plus mince, désignée par 10a, est filetée et re­çoit, vissé sur elle, un manchon taraudé 11 dont le diamètre correspond à la partie de plus grand diamè­tre, désignée par 10b, de la barrette 10. Le diamètre de la partie 10b de la barrette 10 et du manchon 11 correspond au diamètre des trous, désignés par 12, que présentent les bras 8b de la bride diamétrale de maintien 8 de la glace, alors que la partie cen­trale de la barrette 10, désignée par 10c, a un dia­mètre qui correspond à celui du trou, désigné par 13, que présente chacun des gonds 3b. Les parties 10b et 10c de la barrette 10 sont reliées par un chanfrein 14 alors que l'extrémité antérieure du manchon 11 pré­sente un chanfrein 15.The assembly between the ends of the arms 8b and each of the hinges 3 b is obtained through a bar 10 to which floors the terminal portion, the thinner, designated 10a, is threaded and receives, screwed onto it, a threaded sleeve 11, the diameter of which corresponds to the part of larger diameter, designated by 10 b , of the bar 10. The diameter of the part 10 b of the bar 10 and of the sleeve 11 corresponds to the diameter of the holes, designated by 12, which have the arms 8 b of the diametrical flange holding 8 the glass, while the central part of the bar 10, designated by 10 c , has a diameter which corresponds to that of the hole, designated by 13, which each of the hinges 3 has b . The parts 10b and 10c of the bar 10 are connected by a chamfer 14 while the front end of the sleeve 11 has a chamfer 15.

L'agencement est tel que, lorsque la glace 5 est en place dans le fond-carrure 3, la bride diamétrale de maintien étant appliquée sur elle, il faut exercer une légère force sur les ex­trémités des bras 8b pour amener les trous 12 de ceux-ci en regard du trou 13 de chacun des gonds 3b. Les barrettes 10 sont mises en place et les manchons 11 vissés sur chacune d'elles. Les chan­freins 14 et 15, coopérant avec des entrées coni­ques 16 que présentent les trous 12, aident à la mise en place des barrettes et manchons dès lors que les trous 12 peuvent ne pas être en parfait alignement avec les trous 13. Les barrettes exer­cent alors une pré-tension sur la bride diamétrale 8 qui, de ce fait, exerce à son tour une force axia­le élastique sur la glace, appliquant celle-ci axia­lement contre le rehaut 7. De la sorte, la glace est fermement maintenue en place et ne risque pas, quand bien même sa friction sur la garniture d'étanchéité 6 n'est pas importante, de se séparer intempestive­ment du corps de boîte.The arrangement is such that, when the crystal 5 is in place in the backband 3, the diametrical support flange being applied to it, it is necessary to exert a slight force on the ends of the arms 8 b to bring the holes 12 of these opposite hole 13 of each of the hinges 3 b . The bars 10 are put in place and the sleeves 11 screwed onto each of them. The chamfers 14 and 15, cooperating with conical inlets 16 which have the holes 12, help in the positioning of the bars and sleeves as soon as the holes 12 may not be in perfect alignment with the holes 13. The bars then exert a pre-tension on the diametral flange 8 which, in turn, exerts an elastic axial force on the glass, applying the latter axially against the flange 7. In this way, the glass is firmly held in place and does not risk, even if its friction on the seal 6 is not significant, to inadvertently separate from the box body.

Les parties de la bride 10 et du manchon 11 qui débordent des bras 8b de la bride une fois le montage effectué servent de moyens d'accrochage du bracelet 9.The parts of the flange 10 and of the sleeve 11 which project beyond the arms 8b of the flange once the assembly has been carried out serve as attachment means for the bracelet 9.

L'extraction de la glace, une fois la bride diamétrale de maintien 8 démontée, s'effectue aisément, le corps de boîte présentant, au droit d'un des deux gonds 3b, un onglet 17 qui permet d'in­troduire une lame dans une gorge annulaire 18 que présente à cet effet la glace 5.The extraction of the ice, once the diametrical holding flange 8 removed, is easily carried out, the box body having, at the right of one of the two hinges 3 b , a tab 17 which makes it possible to introduce a blade into an annular groove 18 which the glass 5 has for this purpose.

Il est à remarquer que la mise à l'heure, voire le remontage si le mouvement est mécanique, s'effectue à l'aide d'un étrier semi-circulaire 19 (fig. 4),situé sous le fond 3a,articulé sur une piè­ce circulaire 20 montée rotativement sur le fond. Cet étrier peut occuper deux positions, l'une de tra­vail, dans laquelle il est perpendiculaire au plan de la boîte et peut être saisi en vue de permettre l'entraînement de la pièce 20, et l'autre, de repos, représentée au dessin, dans laquelle il est rabattu dans le plan de la boîte.It should be noted that the time setting, or even the winding if the movement is mechanical, is carried out using a semi-circular stirrup 19 (fig. 4), located under the bottom 3 a , articulated on a circular piece 20 rotatably mounted on the bottom. This stirrup can occupy two positions, one working, in which it is perpendicular to the plane of the box and can be grasped in order to allow the drive of the part 20, and the other, of rest, shown in the drawing , in which it is folded down in the plane of the box.

En variante, on pourra prévoir que les gonds 3b de fixation du bracelet et de la bride dia­métrale soient remplacés par des anses. Dans ce cas, les bras 8b pourront s'engager entre les deux anses, le bracelet étant lui-même engagé entre lesdits bras.As a variant, provision may be made for the hinges 3 b for fixing the bracelet and the diametrical flange to be replaced by handles. In this case, the arms 8b can engage between the two handles, the bracelet itself being engaged between said arms.

Chaque paire de bras 8b pourra être rem­placée par un bras unique se terminant par une four­chette dont les branches s'engageront sur les gonds de la boîte ou entre les anses de celle-ci.Each pair of arms 8b can be replaced by a single arm ending in a fork, the branches of which engage on the hinges of the box or between the handles of the latter.

En variante également, on pourra prévoir que la bride diamétrale présente, à des fins décora­tives, deux bras radiaux supplémentaires, disposés perpendiculairement à sa partie principale; ces bras pourraient même être fixés, par leurs extrémités, au corps de boîte.Alternatively also, it may be provided that the diametrical flange has, for decorative purposes, two additional radial arms, arranged perpendicular to its main part; these arms could even be fixed, by their ends, to the box body.

La fixation de la bride au corps de boîte pourra être différente de celle qui a été décrite et représentée et, en particulier, être indépendante des moyens d'attache du bracelet.The attachment of the flange to the box body may be different from that which has been described and shown and, in particular, be independent of the means of attachment of the bracelet.

Enfin, on pourra prévoir que la partie centrale annulaire 8a de la bride porte un tour d'heures.Finally, provision can be made that the annular central portion 8a of the flange carries a tower hours.
