Description

La présente invention est relative à une boíte pour instrument de petit volume, notamment une montre, comprenant une carrure et un fond amovible appliqué sous la carrure.The present invention relates to a box for small instrument volume, in particular a watch, comprising a middle and a removable back applied under the middle.

Ce genre de boíte est couramment utilisée pour habiller une montre-bracelet. Le fond peut être soit vissé, soit cranté avec éventuellement interposition entre le fond et la carrure d'une garniture d'étanchéité. Poser ou déposer un tel fond ne peut se faire qu'à l'aide d'outils particuliers et ces opérations sont généralement réservées à un horloger, comme cela est apparent dans les deux constructions prises en exemple ci-dessous :This kind of box is commonly used to dress a wristwatch. The bottom can be either screwed or notched with possibly interposition between the base and the middle part of a seal. Ask or depositing such a fund can only be done using special tools and these operations are generally reserved for a watchmaker, as is apparent in the two constructions taken as an example below:

Le document CH 251 447 montre un fond ajusté à cran sous une carrure. La boíte comprend une carrure-lunette, un cadre d'emboítage ajusté librement dans la carrure, une glace dont le talon est serré entre le rebord intérieur de la carrure-lunette et le cadre d'emboítage, et un fond. Le fond est ajusté librement dans la carrure et est pressé contre un paquetage compressible garnissant la face inférieure du cadre d'emboítage, par deux leviers pivotant chacun sur une arête que présente intérieurement chacun des deux côtés opposés portant les anses de la carrure.The document CH 251 447 shows a bottom adjusted to notch under a middle. The box includes a bezel, a fitted casing frame freely in the middle, a mirror whose heel is tight between the rim interior of the middle-bezel and the casing frame, and a bottom. The bottom is freely adjusted in the middle and is pressed against a package compressible lining the underside of the casing frame, in pairs levers each pivoting on an edge internally presented by each of the two opposite sides carrying the handles of the middle.

Le document CH 329 625 montre un fond appliqué sous une carrure au moyen d'un système à vis. Cette montre comprend une glace dont le bord rabattu vers l'extérieur est pressé contre un joint par un cercle d'encageage sur lequel il repose. Pour maintenir ce dernier dans la boíte, et pour qu'il exerce une pression contre le rebord, le fond, dont le pourtour est rectangulaire comme la carrure, est ajusté dans l'entrée inférieure de celle-ci et présente, sur sa face extérieure, un logement annulaire, dont la paroi extérieure est tangente aux côtés de l'entrée et ouverte à ces endroits de tangence. Dans ce logement est disposée une bague ronde, filetée extérieurement et se vissant dans la carrure aux endroits de tangence susmentionnés. Des encoches facilitent son vissage et son dévissage.The document CH 329 625 shows a background applied under a middle part to the by means of a screw system. This watch includes a crystal whose edge folded outwards is pressed against a joint by a casing ring on which it is based. To keep it in the box, and so that it exerts pressure against the rim, the bottom, the periphery of which is rectangular like the middle part, is adjusted in the lower entry of this one and has, on its outer face, an annular housing, the wall of which outside is tangent to the sides of the entrance and open at these places of tangency. In this housing is arranged a round ring, threaded externally and screwing into the middle at places of tangency mentioned above. Notches facilitate its screwing and unscrewing.

Dans les types de construction sommairement décrits ci-dessus comme dans toutes les autres constructions connues à ce jour, si, pour fonctionner, la montre est équipée d'une pile, l'usager n'aura d'autres ressources que de confier cette montre à un homme du métier pour changer la pile arrivée en fin de vie. In the types of construction briefly described above as in all the other constructions known to date, if, for operate, the watch is equipped with a battery, the user will have no other resources than entrusting this watch to a skilled person to change the battery has reached the end of its life.

Il est vrai que pour pallier cet inconvénient, certains fonds de boíte sont équipés d'une trappe de pile qui consiste en un bouchon vissé ou fixé à baïonnette dans le fond, ce bouchon étant muni d'une fente de vis qui permet à l'usager d'ouvrir lui-même la trappe au moyen d'une pièce de monnaie, comme cela est mis en oeuvre par exemple sur la montre Swatch (marque déposée).It is true that to overcome this drawback, some box funds are equipped with a battery door which consists of a screwed cap or fixed to bayonet at the bottom, this cap being provided with a screw slot which allows the user to open the hatch himself by means of a coin, as implemented for example on the Swatch watch (brand filed).

Cette solution cependant ne saurait convenir à une pile, ou autre source d'énergie de grand diamètre comme on en trouve dans des montres-pager ou encore dans des montres équipées d'un système GPS. Elle ne saurait pas convenir non plus à une montre particulière possédant au moins deux piles. Pour ce type d'instrument de petit volume, il est donc nécessaire de trouver une solution qui permette de déposer tout le fond afin d'accéder librement à la pile (ou aux piles) qui doit (doivent) être échangée (échangées), cet accès devant rester simple à mettre en oeuvre par l'usager, et cela sans devoir faire appel à un outil quelconque.This solution, however, is not suitable for a battery, or other source of large diameter energy as found in pager watches or in watches equipped with a GPS system. She wouldn't know no longer suitable for a particular watch with at least two batteries. For this type of small volume instrument, it is therefore necessary to find a solution that allows you to deposit the entire bottom in order to freely access the battery (or batteries) which must (must) be exchanged (exchanged), this access must remain simple to implement by the user, and without having to use any tool.

On notera encore que dans ce type d'instrument (pager ou GPS par exemple) la source d'alimentation doit être échangée fréquemment, cela étant dû à la forte consommation du système. Cet échange doit donc pouvoir être effectué rapidement et cela par l'usager lui-même qui gardera sur lui des piles de rechange.It should also be noted that in this type of instrument (pager or GPS by example) the power source must be exchanged frequently, this being due to the high consumption of the system. This exchange must therefore be able to be carried out quickly and this by the user himself who will keep batteries on him spare.

Pour résoudre ce problème, la présente invention propose un fond maintenu sous la carrure au moyen d'au moins un rail, ce rail présentant une première portion longitudinale arrangée pour être glissée dans une rainure pratiquée dans la carrure et une seconde portion longitudinale arrangée pour coiffer un bord du fond quand ladite première portion est introduite dans ladite rainure pour fixer ledit fond sous ladite carrure.To solve this problem, the present invention provides a background maintained under the middle by means of at least one rail, this rail having a first longitudinal portion arranged to be slid into a groove practiced in the middle and a second longitudinal portion arranged for cap a bottom edge when said first portion is introduced into said groove for fixing said bottom under said middle.

Les caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre, faite en regard du dessin annexé et donnant, à titre d'exemple explicatif, mais nullement limitatif, plusieurs formes avantageuses de réalisation de l'invention, dessin dans lequel :

  • - la figure 1 est une vue en perspective du dessous de la boíte selon l'invention, et selon son acception la plus évoluée,

  • - la figure 5 montre un système de blocage possible du fond de boíte sur la carrure,
  • - la figure 6 est une vue en coupe partielle de la boíte selon l'invention et selon son acception la plus simple, et
  • - la figure 7 est une coupe partielle montrant une variante de construction à celle présentée en figure 2.
  • The characteristics and advantages of the present invention will emerge from the description which follows, given with reference to the appended drawing and giving, by way of explanatory example, but in no way limiting, several advantageous embodiments of the invention, drawing in which:
  • - Figure 1 is a perspective view from below of the box according to the invention, and according to its most advanced meaning,
  • FIG. 2 is a section through the box of FIG. 1, section made along the line ll-ll,
  • - Figure 3 is a section in the box of Figure 1, section operated along the line lll-lll,
  • FIG. 4 is an exploded perspective view of the parts closing off the back of the middle part of the box according to the invention,
  • - Figure 5 shows a possible locking system of the bottom of the case on the middle,
  • - Figure 6 is a partial sectional view of the box according to the invention and in its simplest sense, and
  • FIG. 7 is a partial section showing a construction variant to that presented in FIG. 2.
  • La vue en perspective de la figure 1 présente une boíte de montre 1 selon la présente invention et selon son acception la plus évoluée. On reconnaít une carrure 2 à laquelle sont intégrées diverses cornes 30 qui serviront à attacher les brins d'un bracelet. A l'intérieur de cette carrure 2 prend place le mouvement de la montre ainsi que tous les composants qui peuvent l'accompagner, comme, par exemple une électronique pager ou GPS ainsi qu'une source d'énergie se présentant sous la forme d'une ou de deux piles. Un fond amovible 3 est appliqué sous la carrure 2. Si nécessaire, une garniture d'étanchéité 4 (voir figures 2 et 3) est interposée entre la carrure 2 et le fond 3.The perspective view of Figure 1 shows a watch box 1 according to the present invention and according to its most advanced meaning. We recognize a middle part 2 in which various horns 30 are integrated which will serve to attach the strands of a bracelet. Inside this middle part 2 takes place the watch movement as well as all the components that can accompany it, like, for example an electronic pager or GPS as well an energy source in the form of one or two batteries. A removable base 3 is applied under the middle part 2. If necessary, a seal 4 (see Figures 2 and 3) is interposed between the middle part 2 and the bottom 3.

    Comme le montre la figure 1, la boíte de l'invention est remarquable en ce que le fond 3 est maintenu sous la carrure 2 au moyen de deux rails 5 et 6 situés de part et d'autre du fond 3. Comme cela est visible sur la figure 2 qui est une coupe selon la ligne ll-ll de la figure 1, le rail 5 présente une première portion longitudinale 7 arrangée pour être glissée dans un logement ou rainure 9 pratiqué dans la carrure 2. Le rail 5 présente aussi une seconde portion longitudinale 11 arrangée pour coiffer un bord 13 du fond 3 quand ladite première portion 7 est introduite dans ledit logement ou rainure 9. La figure 2 montre aussi le rail 6 construit analogiquement au rail 5. Ainsi le rail 6 présente une première portion longitudinale 8 arrangée pour être glissée dans un logement ou rainure 10 pratiqué dans la carrure 2. Le rail 6 présente aussi une seconde portion longitudinale 12 arrangée pour coiffer un bord 14 du fond 3 quand ladite première portion 8 est introduite dans ledit logement ou rainure 10. On comprendra donc que quand les rails 5 et 6 sont en place le fond 3 est fixé sous la carrure 2.As shown in Figure 1, the box of the invention is remarkable in that the base 3 is held under the middle 2 by means of two rails 5 and 6 located on either side of the bottom 3. As can be seen in Figure 2 which is a section along line ll-ll of Figure 1, the rail 5 has a first longitudinal portion 7 arranged to be slid into a housing or groove 9 in the middle 2. The rail 5 also has a second longitudinal portion 11 arranged to cover an edge 13 of the bottom 3 when said first portion 7 is introduced into said housing or groove 9. The Figure 2 also shows rail 6 constructed analogously to rail 5. Thus rail 6 has a first longitudinal portion 8 arranged to be slid into a housing or groove 10 formed in the middle part 2. The rail 6 also has a second longitudinal portion 12 arranged to cover an edge 14 of the bottom 3 when said first portion 8 is introduced into said housing or groove 10. It will therefore be understood that when the rails 5 and 6 are in place the case back 3 is fixed under the middle part 2.

    Pour compléter la boíte 1 représentée aux figures 2 et 3, la carrure 2 porte sur sa partie supérieure une lunette 31 sous laquelle est appliquée une glace 32. L'étanchéité entre la lunette 31 et la glace 32 est assurée par une garniture 33. L'étanchéité entre la lunette 31 et la carrure 2 est assurée par une garniture 34.To complete the box 1 shown in Figures 2 and 3, the middle part 2 carries on its upper part a telescope 31 under which is applied a glass 32. The seal between the lens 31 and the glass 32 is provided by a gasket 33. The seal between the bezel 31 and the middle part 2 is provided by a garnish 34.

    L'invention pourrait s'arrêter là et se contenter de disposer deux rails 5 et 6 pour bloquer le fond 3 sous la carrure 2. Dans ce cas, pour déposer le fond 3, l'usager fait glisser l'un après l'autre les rails 5 et 6 hors de leur logement respectif, après quoi le fond 3 peut être enlevé. Pour faciliter cette extraction chacun des rails peut être pourvu d'une excroissance à son extrémité (non représentée sur les dessins). Pour fermer la boíte on applique le fond 3 sous la carrure 2 et on fait glisser d'abord la première portion 7 du rail 5 dans sa rainure 9, la seconde portion 11 de ce rail appuyant alors sur le bord 13 du fond 3, puis la première portion 8 du rail 6 dans sa rainure 10, la seconde portion de ce rail appuyant alors sur le bord 14 du fond 3. Dans le cas qui vient d'être exposé, on notera que les rails sont indépendants l'un de l'autre et pas nécessairement parallèles entre eux.The invention could stop there and be content with having two rails 5 and 6 to block the back 3 under the middle part 2. In this case, to deposit the bottom 3, the user slides the rails 5 and 6 one after the other out of their respective housing, after which the bottom 3 can be removed. To facilitate this extraction each of the rails can be provided with a projection at its end (not shown in the drawings). To close the box we apply the bottom 3 under the middle 2 and the first portion 7 of the rail 5 in its groove 9, the second portion 11 of this rail then pressing on the edge 13 of the bottom 3, then the first portion 8 of the rail 6 in its groove 10, the second portion of this rail then pressing on the edge 14 of the bottom 3. In the case which has just been exposed, it will be noted that the rails are independent one of the other and not necessarily parallel to each other.

    On a cependant jugé utile et commode de réunir les deux rails 5 et 6 par une traverse 15 comme cela est représenté sur les figures 1, 3, 4 et 5. La traverse 15 forme avec les rails 5 et 6, disposés parallèlement, un étrier référencé 16 et qui est bien apparent sur les figures 1 et 4. Cet étrier 16 a l'avantage de présenter d'une part une seule et unique pièce de fermeture moins difficile à égarer et d'autre part des moyens de préhension 17 pour extraire simultanément et manuellement les rails 5 et 6 hors de leur logement respectif 9 et 10 pour séparer ainsi le fond 3 de la carrure 2. Un exemple de moyens de préhension va être décrit maintenant :However, it was considered useful and convenient to combine the two rails 5 and 6 by a cross member 15 as shown in FIGS. 1, 3, 4 and 5. The cross member 15 forms with the rails 5 and 6, arranged in parallel, a stirrup referenced 16 and which is clearly visible in FIGS. 1 and 4. This stirrup 16 has the advantage of having on the one hand a single closure part less difficult to misplace and on the other hand gripping means 17 for extract rails 5 and 6 simultaneously and manually from their housing respective 9 and 10 to separate the case back 3 from the middle part 2. An example of gripping means will now be described:

    Le moyen de préhension 17 est illustré sur les figures 1 et 3. La traverse 15 est munie d'un bourrelet 18 et le fond 3 est muni d'une creusure ou onglet 19 qui fait face au bourrelet 18. Pour extraire l'étrier 16, on glisse un ongle dans la creusure 19 jusqu'à ce que la pointe de l'ongle appuie sur le bourrelet 18. On exerce avec l'ongle une force (flèche A) contre le bourrelet 18 ce qui a pour effet de dégager la traverse 15 de la carrure 2 (flèche B) et d'extraire les rails 5 et 6 de leur logement.The gripping means 17 is illustrated in Figures 1 and 3. The cross member 15 is provided with a bead 18 and the bottom 3 is provided with a recess or tab 19 which faces the bead 18. To extract the stirrup 16, slide a nail in the recess 19 until the tip of the nail presses on the bead 18. A force is applied with the nail (arrow A) against the bead 18 which has the effect of clearing the cross member 15 from the middle part 2 (arrow B) and extract the rails 5 and 6 from their housing.

    La figure 4 illustre les opérations à effectuer pour fermer la boíte. On commence par appliquer le fond 3 sous la carrure 2 dans le sens de la flèche C. On maintient sous le fond 3 une certaine force pour écraser quelque peu la garniture d'étanchéité 4 pendant qu'on introduit l'extrémité des rails 5 et 6 dans leur logement et qu'on les glisse, dans le sens de la flèche D, jusqu'au fond de leur logement, en pressant sur la traverse 15. Figure 4 illustrates the operations to be performed to close the box. We start by applying the back 3 under the middle 2 in the direction of the arrow C. A certain force is maintained under the bottom 3 to slightly crush the seal 4 while inserting the end of the rails 5 and 6 in their housing and that they slide, in the direction of arrow D, until bottom of their housing, pressing on the cross 15.

    Pour faire pendant au bourrelet 18 et assurer ainsi une certaine symétrie au fond 3, on a équipé le fond d'un second bourrelet 35 (figures 1 et 3).To counterbalance the bead 18 and thus ensure a certain symmetry at the bottom 3, the bottom has been fitted with a second bead 35 (FIGS. 1 and 3).

    Une fois en place et comme décrit ci-dessus, l'extérieur 16 n'est pas assuré contre une extraction intempestive due, par exemple, à un objet se présentant devant les moyens de préhension dont est pourvue la traverse 15. Pour éviter cela, on peut équiper le fond 3 d'un cran 20 comme le montre la figure 5. Ce cran 20 est susceptible de recevoir un verrou 21 disposé sur la traverse 15. Ce verrou présente, par rapport à la traverse 15, une élasticité suffisante pour fléchir lorsqu'il bute par son plan incliné 36 sur l'arête 37 du fond 3 jusqu'à ce que sa pointe tombe dans le cran 20. Pour dégager le verrou, il suffit d'agir avec un ongle sur le plan 36 pour le faire fléchir et dégager ainsi tout l'étrier 16.Once in place and as described above, the exterior 16 is not insured against untimely extraction due, for example, to an object having before the gripping means which is provided with the cross 15. To avoid this, the bottom 3 can be fitted with a notch 20 as shown in the Figure 5. This notch 20 is capable of receiving a lock 21 disposed on the cross member 15. This lock has, with respect to the cross member 15, an elasticity sufficient to bend when it abuts by its inclined plane 36 on the edge 37 of the bottom 3 until its tip falls into the notch 20. To release the lock, just act with a fingernail on plane 36 to make it bend and thus release the entire stirrup 16.

    La coupe de la figure 6 présente une boíte de montre 1 selon la présente invention et selon son acception la plus simple. Ici, le fond 3 est maintenu sous la carrure 2 au moyen d'un seul rail 5, qui présente, rappelons-le, une première portion longitudinale 7 arrangée pour être glissée dans une rainure 9 pratiquée dans la carrure 2 et une seconde portion longitudinale 11 arrangée pour coiffer un bord 13 du fond 3. Dans ce cas, comme cela apparaít sur la partie droite de la figure 6, l'autre bord 45 du fond 3 se termine en pointe, arrangée pour être logée dans une rainure 9 ménagée dans la carrure 2. Pour appliquer le fond 3 sous la carrure 2, on commence par introduire sous un certain angle l'arête pointue 45 dans la rainure 9. On rabat ensuite le fond 3 sous la carrure 2 et l'on fixe le fond 3 en introduisant le rail 5.The section of Figure 6 shows a watch box 1 according to the present invention and in its simplest sense. Here, the bottom 3 is maintained under the middle 2 by means of a single rail 5, which has, remember, a first longitudinal portion 7 arranged to be slid into a groove 9 formed in the middle part 2 and a second longitudinal portion 11 arranged to cover an edge 13 of the bottom 3. In this case, like this appears on the right part of Figure 6, the other edge 45 of the bottom 3 is ends in a point, arranged to be housed in a groove 9 formed in the middle 2. To apply the back 3 under the middle 2, we start with introduce the pointed edge 45 into the groove 9 at a certain angle. then the bottom 3 under the middle 2 and the bottom 3 is fixed by introducing the rail 5.

    Qu'il s'agisse de l'acception la plus simple de l'invention (figure 6) ou de son acception la plus évoluée (figure 2), les rails 5, 6 présentent une section droite en forme de Z, la première portion longitudinale 7 comportant un premier talon rectangulaire glissé dans la rainure 9 et la seconde portion longitudinale 11 comportant un second talon rectangulaire dont la face supérieure 40 appuie sur le bord 13 du fond 3 (voir figure 6).Whether it is the simplest meaning of the invention (Figure 6) or its most advanced meaning (Figure 2), the rails 5, 6 have a cross-section straight Z-shaped, the first longitudinal portion 7 comprising a first rectangular heel slipped in groove 9 and the second portion 11 with a second rectangular heel, the face of which upper 40 presses on the edge 13 of the bottom 3 (see FIG. 6).

    L'invention n'est pas limitée à cette section droite qui peut prendre d'autres profils comme par exemple, celui montré en figure 7. Ici, la première portion longitudinale 7 du rail 5 comporte un talon rectangulaire glissé dans la rainure 9 et la seconde portion longitudinale 11 du rail 5 comporte un coin présentant une face inclinée 41 arrangée pour appuyer sur un bord 13 du fond 3, ce bord étant taillé en biseau. The invention is not limited to this cross section which can take other profiles such as the one shown in figure 7. Here, the first longitudinal portion 7 of the rail 5 has a rectangular heel slid into the groove 9 and the second longitudinal portion 11 of the rail 5 has a corner having an inclined face 41 arranged to press on an edge 13 of the bottom 3, this edge being cut at a bevel.

    L'invention qui vient d'être décrite montre qu'un instrument de petit volume peut être muni d'un fond qui peut être posé ou déposé sans l'aide d'outil par l'usager. Ainsi, si une pile doit être échangée fréquemment, cet usager n'a-t-il pas à demander l'aide d'un spécialiste.The invention which has just been described shows that a small instrument volume can be provided with a bottom which can be installed or removed without assistance of tool by the user. So if a battery needs to be changed frequently, this does the user not have to seek the help of a specialist.
