Abstract

The device has a set of teeth (32) connected to a middle (22) of a case of a watch, and another set of teeth (42) provided on a base (23) and cooperating with the former set of teeth. The teeth orient the base with respect to the middle to a desired position, and are blocked in rotation with respect to each other. A blocking unit (47) e.g. nut, blocks translational displacement of the base with respect to the middle and connects the base with the middle. The blocking unit is distinct from the middle and the base. An independent claim is also included for a method for orienting and fixing a base on a middle of a case of a watch.

Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, un dispositif d'orientation et de fixation d'un fond sur une carrure d'une boite de montre. L'invention concerne également un procédé d'orientation et de fixation d'un fond sur une carrure d'une boite de montre au moyen d'un tel dispositif, permettant d'orienter le fond par rapport à la carrure dans une position déterminée.The present invention relates to the field of watchmaking. It relates, more particularly, a device for orienting and fixing a bottom on a middle part of a watch case. The invention also relates to a method of orienting and fixing a bottom on a middle of a watch case by means of such a device, for orienting the bottom relative to the middle part in a specific position.

Etat de la techniqueState of the art

La fabrication et le montage d'un fond de boite à visser sur la carrure d'une boîte de montre sont bien connus. En général, les fonds de boite vissés ne sont pas orientés. Toutefois, pour des raisons esthétiques, il est primordial, lorsque la face externe du fond porte une marque ou un logo, de pouvoir garantir que le fond soit ramené dans une orientation déterminée par rapport à la carrure lorsqu'il est en position vissée.The manufacture and assembly of a screw-down box on the middle of a watch case are well known. In general, the screwed bottoms are not oriented. However, for aesthetic reasons, it is essential, when the outer face of the bottom bears a mark or a logo, to be able to ensure that the bottom is brought back in a given orientation relative to the middle part when it is in the screwed position.

Différentes solutions existent pour permettre l'orientation d'un fond de boite vissé. Par exemple, il est possible de prévoir un début de filetage et un taraudage appariés et toujours identiques, afin de conserver l'orientation du fond, même après démontage par exemple lorsque la montre doit être réparée. Théoriquement, ce principe fonctionne correctement. Toutefois, il est très difficile de le réaliser en production.Various solutions exist to allow the orientation of a screwed bottom. For example, it is possible to provide a threading start and tapping paired and always identical, to maintain the orientation of the bottom, even after disassembly for example when the watch must be repaired. Theoretically, this principle works correctly. However, it is very difficult to achieve in production.

Des dispositifs d'orientation et de fixation d'un fond sur une carrure sont décrits par exemples dans les documents CH 696 564 , EP 1 890 203 , WO 2007/028554 et WO 2007/144019 . Les dispositifs décrits dans les documents CH 696 564 et WO 2007/144019 comprennent des éléments portant des butées d'arrêt en rotation. En outre, le document WO 2007/144019 décrit que la carrure et le fond présentent chacun une portion filetée coopérant entre elles. Ces portions filetées font parties intégrantes de la carrure et du fond. De tels éléments sont complexes à fabriquer. Le document EP 1 890 203 décrit un dispositif comportant un fond comprenant une portion filetée dans un premier sens, la carrure comprenant une portion filetée dans un deuxième sens opposé, et un élément intermédiaire présentant une première portion filetée coopérant avec la portion filetée du fond et une deuxième portion filetée coopérant avec la portion filetée de la carrure. De fait de ces nombreuses portions filetées, le dispositif est complexe à réaliser et n'offre pas une grande précision de l'orientation. Le document WO 2007/028554 décrit un dispositif utilisant de nombreux éléments intermédiaires, augmentant les temps de production et de montage.Devices for orienting and fixing a base on a caseband are described for example in the documents CH 696 564 , EP 1 890 203 , WO 2007/028554 and WO 2007/144019 . The devices described in the documents CH 696 564 and WO 2007/144019 comprise elements bearing rotational stops. In addition, the document WO 2007/144019 describes that the middle and the bottom each have a threaded portion cooperating with each other. These threaded portions are integral parts of the middle part and the bottom. Such elements are complex to manufacture. The document EP 1 890 203 describes a device comprising a bottom comprising a threaded portion in a first direction, the middle part comprising a threaded portion in a second opposite direction, and an intermediate element having a first threaded portion cooperating with the threaded portion of the bottom and a second threaded portion cooperating with the threaded portion of the middle part. Because of these many threaded portions, the device is complex to produce and does not offer a great precision of orientation. The document WO 2007/028554 describes a device using many intermediate elements, increasing the production and assembly time.

Un but de la présente invention est donc de pallier ces inconvénients, en proposant un dispositif d'orientation et de fixation d'un fond sur une carrure comprenant un nombre de pièces limité et permettant un réglage simple de l'orientation du fond par rapport à la carrure.An object of the present invention is therefore to overcome these disadvantages, by providing a device for orienting and fixing a bottom to a middle part comprising a limited number of parts and allowing a simple adjustment of the orientation of the bottom with respect to the build.

Other features of the present invention will emerge more clearly on reading the description which follows, made with reference to the appended drawings, in which:
  • the figure 1 is a sectional view of a first variant embodiment of the device according to the invention,
  • the figure 2 is a detail view of the figure 1 ,
  • the figure 3 is a sectional view of a second variant embodiment of the device according to the invention, and
  • the figure 4 is a detail view of the figure 3 . Mode (s) of realization of the invention

En référence aux figures 1 et 2, il est représenté une première variante de réalisation de la présente invention, selon laquelle les premiers moyens d'indexation sont liés directement à la carrure.With reference to Figures 1 and 2 , there is shown a first embodiment of the present invention, according to which the first indexing means are directly connected to the middle part.

D'une manière classique, la boite de montre 1 comprend notamment une carrure 2 et un fond 3. Les autres éléments traditionnellement utilisés dans une boite de montre étant connus de l'homme du métier et ne faisant pas partie de la présente invention, ne seront pas décrits ici.In a conventional manner, the watch case 1 comprises in particular a middle 2 and a bottom 3. The other elements traditionally used in a watch case being known to those skilled in the art and not forming part of the present invention, do not will not be described here.

Selon l'invention, la carrure 2 comprend sur son pourtour interne, du côté du fond 3, une première denture 4 constituant les premiers moyens d'indexation. La denture 4 peut être à 90° et peut comprendre par exemple 120 dents.According to the invention, the middle part 2 comprises on its inner periphery, on the side of the bottom 3, a first toothing 4 constituting the first indexing means. The toothing 4 may be 90 ° and may include, for example, 120 teeth.

De la carrure 2 de forme générale circulaire saillit une collerette annulaire 5, du côté du fond 3, à distance du pourtour extérieur de la carrure 2. La collerette annulaire 5 définit ainsi un rebord périphérique extérieur 6, dont le rôle sera expliqué ci-dessous.The middle part 2 of circular general shape protrudes an annular flange 5, the side of the bottom 3, away from the outer periphery of the middle part 2. The Annular flange 5 thus defines an outer peripheral flange 6, the role of which will be explained below.

La collerette annulaire 5 présente un filetage extérieur 8. Entre le pourtour interne de la carrure 2 et la collerette annulaire 5, il est prévu une gorge annulaire 10 agencée pour recevoir un joint d'étanchéité 11.The annular collar 5 has an external thread 8. Between the inner periphery of the middle part 2 and the annular flange 5, there is provided an annular groove 10 arranged to receive a seal 11.

Le fond 3 comprend, du côté de la carrure 2, une deuxième denture 13, constituant les seconds moyens d'indexation, et agencée pour coopérer avec la première denture 4. Il est bien évident que le nombre de dents de la denture peut varier et dépendre du nombre de positions dans lesquelles on souhaite orienter le fond 3 par rapport à la carrure 2. De même, il est bien évident que les dentures utilisées dans la présente invention peuvent être remplacées par tout moyen équivalent, tels que des gouges, des rainures, ou des cannelures, le nombre de ces éléments dépendant du nombre de position dans lesquelles on souhaite pouvoir orienter le fond par rapport à la carrure.The bottom 3 comprises, on the side of the middle 2, a second toothing 13, constituting the second indexing means, and arranged to cooperate with the first toothing 4. It is obvious that the number of teeth of the toothing can vary and depend on the number of positions in which it is desired to orient the bottom 3 relative to the middle part 2. Similarly, it is obvious that the teeth used in the present invention can be replaced by any equivalent means, such as gouges, grooves , or grooves, the number of these elements depending on the number of positions in which it is desired to be able to orient the bottom relative to the middle part.

Le fond 3 comprend également un rebord périphérique 15, présentant une forme complémentaire à la base de la carrure 2, de sorte que ladite carrure 2 repose sur ledit rebord périphérique 15, de son pourtour intérieur à sa collerette annulaire 5. La base de la carrure 2 constitue ainsi une butée pour le fond 3.The bottom 3 also comprises a peripheral flange 15, having a shape complementary to the base of the middle part 2, so that said middle part 2 rests on said peripheral flange 15, from its inner periphery to its annular flange 5. The base of the middle part 2 thus constitutes a stop for the bottom 3.

Sur son pourtour extérieur, le rebord 15 du fond 3 présente une rainure 16 dont le rôle sera expliqué ci-dessous.On its outer periphery, the flange 15 of the bottom 3 has a groove 16 whose role will be explained below.

La carrure 2 et le fond 3 sont assemblés au moyen d'un organe de blocage 17, formé d'un écrou extérieur, et agencé pour venir reposer sur le rebord périphérique extérieur 6 de la carrure. L'organe de blocage 17 présente un filetage intérieur 19, agencé pour coopérer avec le filetage extérieur 8 prévu sur la collerette annulaire 5 de la carrure 2. De plus, l'organe de blocage 17 comporte une portée 21 agencée pour passer sous la collerette annulaire 5 et venir circuler dans la rainure 16 prévue sur le fond 3, constituant en même temps une butée pour ledit fond 3.The middle part 2 and the bottom 3 are assembled by means of a locking member 17, formed of an outer nut, and arranged to rest on the outer peripheral edge 6 of the middle part. The locking member 17 has an internal thread 19, arranged to cooperate with the external thread 8 provided on the annular collar 5 of the middle part 2. In addition, the locking member 17 comprises a bearing 21 arranged to pass under the collar annular 5 and circulate in the groove 16 provided on the bottom 3, constituting at the same time a stop for said bottom 3.

Ainsi, lorsque le fond 3 est assemblé à la carrure 2, tout déplacement en translation du fond 3 par rapport à la carrure 2 est empêché par l'organe de blocage 17, vissé à la carrure 2 par la collerette annulaire 5 d'une part, et maintenant le fond 3 en butée contre sa portée 21 d'autre part.Thus, when the bottom 3 is assembled to the middle part 2, any displacement in translation of the bottom 3 relative to the middle part 2 is prevented by the body of blocking 17, screwed to the middle part 2 by the annular flange 5 on the one hand, and now the bottom 3 abuts against its bearing surface 21 on the other hand.

Le fond 3 est orienté par rapport à la carrure selon le procédé suivant:

  • positionnement du fond 3 contre la carrure 2 en orientant ledit fond 3 par rapport à la carrure 2 au moyen des moyens d'indexation 4 et 13,
  • fixation du fond 3 à la carrure 2 au moyen de l'organe de blocage 17.
The bottom 3 is oriented relative to the middle part according to the following method:
  • positioning the base 3 against the middle part 2 by orienting said base 3 with respect to the middle part 2 by means of the indexing means 4 and 13,
  • fixing the bottom 3 to the middle part 2 by means of the locking member 17.

Plus précisément, le fond 3 est tout d'abord placé à proximité de la carrure 2 et orienté selon la position souhaitée. Ensuite, le fond 3 est poussé contre la carrure 2, en faisant coopérer les dentures 4 et 13, selon l'orientation souhaitée du fond 3. Celui-ci est alors bloqué en rotation par les dentures 4 et 13 qui coopèrent ensemble. Lorsque le fond 3 est positionné, son rebord périphérique 15 vient en butée contre la base de la carrure 2, entre son pourtour intérieur et sa collerette annulaire 5. Puis l'organe de blocage 17 est vissé sur la collerette annulaire 5 de la carrure 2, sa portée 21 venant circuler dans la rainure 16 du fond 3, empêchant ainsi tout déplacement en translation du fond 3 par rapport à la carrure 2. Le fond 3 est ainsi bloqué en translation. Il est également bloqué en rotation, par exemple en cas de dévissage intempestif de l'organe de blocage 17. L'orientation du fond 3 ne peut être modifiée qu'en démontant l'ensemble. Quand l'ensemble doit être remonté, il est facile de replacer le fond 3 selon la bonne orientation en replaçant correctement sa denture 13 dans la denture 4 de la carrure 2.More specifically, the bottom 3 is first placed close to the middle part 2 and oriented according to the desired position. Then, the bottom 3 is pushed against the middle part 2, by causing the teeth 4 and 13 to cooperate, in the desired orientation of the bottom 3. The latter is then locked in rotation by the teeth 4 and 13 which cooperate together. When the bottom 3 is positioned, its peripheral rim 15 abuts against the base of the middle part 2, between its inner periphery and its annular flange 5. Then the locking member 17 is screwed onto the annular flange 5 of the middle part 2 , its range 21 flowing in the groove 16 of the bottom 3, thus preventing any displacement in translation of the bottom 3 relative to the middle part 2. The bottom 3 is thus locked in translation. It is also locked in rotation, for example in the event of inadvertent unscrewing of the locking member 17. The orientation of the bottom 3 can be modified only by dismantling the assembly. When the assembly must be reassembled, it is easy to replace the bottom 3 in the correct orientation by correctly placing its teeth 13 in the toothing 4 of the middle part 2.

En référence aux figures 3 et 4, il est représenté une deuxième variante de réalisation de la présente invention, selon laquelle les premiers moyens d'indexation sont liés indirectement à la carrure.With reference to Figures 3 and 4 , there is shown a second embodiment of the present invention, wherein the first indexing means are indirectly related to the middle part.

La boite de montre 20 comprend notamment une carrure 22 et un fond 23.The watch case 20 includes in particular a middle part 22 and a bottom 23.

La carrure 22, de forme générale circulaire, comprend sur son pourtour interne, du côté du fond 23, un filetage 24. La base 25 de la carrure 22 comprend une gorge annulaire 26 agencée pour recevoir un joint d'étanchéité 27.The middle part 22, of generally circular shape, comprises on its inner periphery, on the side of the bottom 23, a thread 24. The base 25 of the middle part 22 comprises an annular groove 26 arranged to receive a seal 27.

Selon l'invention, le dispositif d'orientation et de fixation comprend en outre une bague 28 présentant un filetage extérieur 30 destiné à coopérer avec le filetage 24 de la carrure 22. Par ailleurs, la bague 28 présente sur son pourtour interne, une denture 32 constituant les premiers moyens d'indexation. La denture 32 peut être à 90° et peut comprendre par exemple 120 dents. Au-dessus de la denture 32, la bague 28 présente un épaulement circulaire 34 formant un rebord 36, dont le rôle sera décrit ci-dessous.According to the invention, the orientation and fixing device further comprises a ring 28 having an external thread 30 intended to cooperate with the thread 24 of the middle part 22. Moreover, the ring 28 has on its inner periphery, a toothing 32 constituting the first indexing means. The toothing 32 may be at 90 ° and may comprise for example 120 teeth. Above the toothing 32, the ring 28 has a circular shoulder 34 forming a flange 36, the role of which will be described below.

Du fond 23 saillit une collerette annulaire 38, du côté de la carrure 22, à distance du pourtour extérieur du fond 23. La collerette annulaire 38 définit ainsi un rebord périphérique extérieur 40 sur lequel repose la base 25 de la carrure 22. La base 25 de la carrure 22 constitue ainsi une butée pour le fond 23.From the bottom 23 protrudes an annular flange 38, on the side of the middle part 22, away from the outer periphery of the bottom 23. The annular flange 38 thus defines an outer peripheral flange 40 on which the base 25 of the middle part 22 rests. The base 25 of the middle part 22 thus constitutes a stop for the bottom 23.

Du côté de la bague 28, la collerette annulaire 38 présente une denture 42, constituant les seconds moyens d'indexation, et agencée pour coopérer avec la denture 32 de la bague 28. Il est bien évident que le nombre de dents de la denture peut varier et dépendre du nombre de positions dans lesquelles on souhaite orienter le fond 23 par rapport à la carrure 22. De l'autre côté, la collerette annulaire 38 présente un filetage intérieur 44.On the side of the ring 28, the annular flange 38 has a toothing 42, constituting the second indexing means, and arranged to cooperate with the toothing 32 of the ring 28. It is obvious that the number of teeth of the toothing can vary and depend on the number of positions in which it is desired to orient the bottom 23 relative to the middle part 22. On the other side, the annular flange 38 has an internal thread 44.

La collerette annulaire 38 définit un logement intérieur agencé pour recevoir un organe de blocage 47 permettant d'assembler la carrure 22 et le fond 23. L'organe de blocage 47 est formé d'un écrou intérieur, et présente un filetage extérieur 48 coopérant avec le filetage intérieur 44 de la collerette annulaire 38. L'organe de blocage 47 est prolongé, sur son pourtour extérieur, par un rebord 49, agencé pour passer au-dessus de la collerette annulaire 38 et venir s'appuyer sur le rebord 36 de la bague 28. Le rebord 49 de l'organe de blocage 47 est agencé de manière à ce qu'il puisse circuler librement dans l'épaulement 34 de la bague.The annular flange 38 defines an inner housing arranged to receive a locking member 47 for assembling the middle part 22 and the bottom 23. The locking member 47 is formed of an inner nut, and has an external thread 48 cooperating with the internal thread 44 of the annular flange 38. The locking member 47 is extended, on its outer periphery, by a flange 49, arranged to pass over the annular flange 38 and come to rest on the rim 36 of the ring 28. The flange 49 of the locking member 47 is arranged so that it can flow freely in the shoulder 34 of the ring.

Ainsi, lorsque le fond 23 est assemblé à la carrure 22, tout déplacement en translation du fond 23 par rapport à la carrure 22 est empêché par l'organe de blocage 47, vissé au fond 23 par la collerette annulaire 28 d'une part, et maintenu à la carrure 22 par butée de son rebord 49 contre le rebord 36 de la bague 28 d'autre part.Thus, when the bottom 23 is assembled to the middle part 22, any displacement in translation of the bottom 23 relative to the middle part 22 is prevented by the locking member 47, screwed to the bottom 23 by the annular flange 28 on the one hand, and held at the middle 22 by abutment of its flange 49 against the flange 36 of the ring 28 on the other hand.

Le procédé d'orientation et de fixation du fond 23 sur la carrure 22 comprend les étapes suivantes:

  • vissage en butée de la bague 28 sur la carrure 22,
  • positionnement du fond 23 contre la bague 28 en orientant ledit fond 23 par rapport à la carrure 22 au moyen des moyens d'indexation 32 et 42,
  • dévissage de l'ensemble fond 23/bague 28 de la carrure 22,
  • assemblage de l'organe de blocage 47 sur l'ensemble fond 23/bague 28,
  • assemblage de l'ensemble fond 23/bague 28/organe de blocage 47 sur la carrure 22.
The method of orienting and fixing the base 23 to the middle part 22 comprises the following steps:
  • screwing in abutment of the ring 28 on the middle part 22,
  • positioning the base 23 against the ring 28 by orienting said bottom 23 relative to the middle part 22 by means of the indexing means 32 and 42,
  • unscrewing the bottom assembly 23 / ring 28 of the middle part 22,
  • assembly of the locking member 47 on the bottom assembly 23 / ring 28,
  • assembly of the bottom assembly 23 / ring 28 / locking member 47 on the middle part 22.

Plus précisément, la bague 28 est vissée en butée dans la carrure 22 en utilisant comme outil le fond 23 inséré dans ladite bague 28 ou tout autre outil approprié. Si le fond 23 a été utilisé comme outil de vissage, il est retiré de la bague 28. Ensuite, le fond 23 est placé à proximité de la bague 28 et orienté selon la position souhaitée. Puis, le fond 23 est poussé contre la bague 28, son rebord 40 butant contre la bague 28 et la base 25 de la carrure 22, en faisant coopérer les dentures 32 et 42, selon l'orientation souhaitée du fond 23. Celui-ci est alors bloqué en rotation par les dentures 32 et 42 qui coopèrent ensemble. Le fond 23, rendu solidaire en rotation de la bague 28 par les dentures 32 et 42 est ensuite dévissé de la carrure 22, en entrainant avec lui la bague 28. L'organe de blocage 47 est alors vissé sur la collerette annulaire 38 du fond 23, son rebord 49 venant reposer sur le rebord 36 de la bague 28, empêchant ainsi tout déplacement en translation du fond 23 par rapport à la bague 28. Le fond 23, déjà bloqué en rotation, est ainsi également bloqué en translation. L'organe de blocage 47 permet de rendre solidaire le fond 23 de la bague 28. L'ensemble fond 23/bague 28/organe de blocage 47 est ensuite assemblé à la carrure 22 en vissant la bague 28 en butée sur la carrure 22. La bague 28 retrouvant sa position initiale par rapport à la carrure, la bonne orientation du fond 23 par rapport à la carrure 22 est garantie.More specifically, the ring 28 is screwed in abutment in the middle part 22 using as a tool the bottom 23 inserted in said ring 28 or any other suitable tool. If the bottom 23 has been used as a screwdriver, it is removed from the ring 28. Then the bottom 23 is placed near the ring 28 and oriented to the desired position. Then, the bottom 23 is pushed against the ring 28, its rim 40 abutting against the ring 28 and the base 25 of the middle part 22, by causing the teeth 32 and 42 to cooperate, in the desired orientation of the bottom 23. This one is then locked in rotation by the teeth 32 and 42 which cooperate together. The bottom 23, secured in rotation of the ring 28 by the teeth 32 and 42 is then unscrewed from the middle part 22, driving with it the ring 28. The locking member 47 is then screwed on the annular collar 38 of the bottom 23, its flange 49 coming to rest on the flange 36 of the ring 28, thus preventing any displacement in translation of the bottom 23 relative to the ring 28. The bottom 23, already locked in rotation, is thus also locked in translation. The locking member 47 makes it possible to make the bottom 23 of the ring 28 integral. The bottom assembly 23 / ring 28 / locking member 47 is then assembled to the middle part 22 by screwing the ring 28 in abutment on the middle part 22. The ring 28 returning to its original position relative to the middle, the correct orientation of the bottom 23 relative to the middle part 22 is guaranteed.

Quand la montre doit être réparée, il suffit de dévisser l'ensemble fond 23/bague 28/organe de blocage 47 de la carrure pour retirer le fond 23. Au remontage, il suffit de revisser l'ensemble fond 23/bague 28/organe de blocage 47, la bague 28 venant en butée sur la carrure 22 pour retrouver l'orientation initiale du fond 23.When the watch must be repaired, simply unscrew the bottom assembly 23 / ring 28 / locking member 47 of the middle part to remove the bottom 23. When reassembling, simply screw the bottom assembly 23 / ring 28 / body 47, the ring 28 abuts on the middle part 22 to find the initial orientation of the bottom 23.

Si l'on souhaite changer le fond ou simplement modifier son orientation, il suffit de dévisser l'organe de blocage 47 pour libérer le fond 23 de la bague 28, et de repositionner le fond sur la bague en plaçant sa denture 42 dans la denture 32 de la bague 28 selon l'orientation souhaitée. L'ensemble est ensuite remonté comme décrit ci-dessus en garantissant l'orientation du fond par rapport à la carrure.If one wishes to change the bottom or simply change its orientation, simply unscrew the locking member 47 to release the bottom 23 of the ring 28, and reposition the bottom on the ring by placing its toothing 42 in the teeth 32 of the ring 28 according to the desired orientation. The assembly is then reassembled as described above ensuring the orientation of the bottom relative to the middle part.
