ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

La présente invention concerne un élément d'habillage d'une carrure de boite de pièce d'horlogerie comme une lunette de pièce d'horlogerie.The present invention relates to a cladding element of a watch case middle part as a timepiece bezel.

Des éléments d'habillage comme des systèmes de lunettes tournantes 2 connues, visibles à la figure 1, comprennent une lunette tournante 4 se présentant sous la forme d'une pièce annulaire. Cette pièce annulaire possède une face supérieure et une face inférieure, la face supérieure étant la face visible par l'utilisateur. Comme visible à la figure 2, cette lunette 8 comprend, sur sa surface inférieure, un crantage 10. Le système de lunette tournante comprend en outre un moyen ressort 11. Ce moyen ressort 11 est inséré entre la lunette tournante et la carrure 3 de la pièce d'horlogerie 1 lorsque la lunette est montée à force sur la carrure de la pièce d'horlogerie. Ce moyen ressort 11 se présente sous la forme d'un anneau plat comprenant, sur sa face en regard du crantage de la lunette 8, des lamelles. Ces lamelles sont disposées pour présenter une inclinaison par rapport au plan de l'anneau plat. Ces lamelles présentent une certaine élasticité de sorte que les moyens ressort agissent sur la lunette tournante pour exercer une force verticale. Cette force verticale tend à pousser la lunette hors de la carrure de la pièce d'horlogerie.Dressing elements such as rotating eyewear systems 2 known, visible at the figure 1 , comprise a rotating bezel 4 in the form of an annular piece. This annular piece has an upper face and a lower face, the upper face being the face visible by the user. As visible at figure 2 this bezel 8 comprises, on its lower surface, a notch 10. The rotating bezel system further comprises a spring means 11. This spring means 11 is inserted between the rotating bezel and the middle part 3 of the timepiece 1 when the bezel is mounted by force on the middle part of the timepiece. This spring means 11 is in the form of a flat ring comprising, on its face facing the notch of the bezel 8, slats. These slats are arranged to have an inclination relative to the plane of the flat ring. These slats have a certain elasticity so that the spring means act on the rotating bezel to exert a vertical force. This vertical force tends to push the bezel out of the middle of the timepiece.

Ces lamelles servent également à coopérer avec le crantage de la lunette. Les lamelles et le crantage sont alors configurés de sorte que la lunette ne puisse tourner que dans un seul sens, les lamelles s'opposent à la rotation de la lunette si l'utilisateur tente de faire tourner ladite lunette dans le mauvais sens. En général, la lunette et les moyens ressorts sont réalisés en acier qui a l'avantage d'avoir une bonne durée de vie et d'être peu couteux.These slats are also used to cooperate with the notching of the telescope. The slats and the notch are then configured so that the bezel can rotate in one direction, the slats are opposed to the rotation of the telescope if the user tries to rotate the telescope in the wrong direction. In general, the bezel and the spring means are made of steel which has the advantage of having a good life and being inexpensive.

Cette lunette est fixée à la carrure 2 de la boîte de montre par chassage. Pour cela, la carrure présente un épaulement périphérique 2a dans lequel ledit système de lunette tournante est placé. L'épaulement 2a présente une paroi parallèle 2b à l'axe central (C) de la carrure et une paroi perpendiculaire à l'axe central de la carrure. La paroi parallèle 2b dudit épaulement présente une gorge périphérique 2c. La lunette 8 est une pièce annulaire présentant, sur sa face inférieure, un rebord périphérique 8a. Ce rebord est muni d'une saillie 12 continue s'étendant le long dudit rebord vers le centre axial de la lunette. Lorsque ledit système de lunette tournante est monté sur la carrure de la boite de montre par chassage, la saillie continue s'insère dans la gorge périphérique de l'épaulement assurant un maintien vertical de la lunette sur la carrure.This bezel is attached to the middle part 2 of the watch case by hunting. For this, the middle part has a peripheral shoulder 2a in which said rotating bezel system is placed. The shoulder 2a has a wall 2b parallel to the central axis (C) of the middle and a wall perpendicular to the central axis of the middle part. The parallel wall 2b of said shoulder has a peripheral groove 2c. The bezel 8 is an annular piece having, on its underside, a peripheral rim 8a. This flange is provided with a continuous projection 12 extending along said flange towards the axial center of the telescope. When said rotating bezel system is mounted on the middle of the watch case by driving, the continuous projection is inserted into the peripheral groove of the shoulder ensuring vertical retention of the bezel on the middle part.

Un inconvénient de ce système est qu'il n'est pas démontable. En effet, la lunette des systèmes à lunette tournante selon l'art antérieur est chassée à la carrure de la boîte de sorte qu'une tentative de désolidarisation du système de lunette tournante doit se faire généralement par arrachage dudit système ce qui entraîne sa détérioration.A disadvantage of this system is that it is not removable. Indeed, the bezel rotating systems according to the prior art is driven to the middle of the box so that an attempt to separate the rotating bezel system must be generally by tearing said system causing its deterioration.

Bien sûr, cela dépend du matériau dans lequel le système de lunette est constitué. Une lunette en plastique qui est chassé sur la carrure sera plus facile à enlever qu'une lunette en acier. Cette prédisposition est la conséquence du fait que le plastique à des propriétés élastiques faisant qu'il se déforme plus facilement que l'acier ce qui rend le montage et le démontage d'une lunette en plastique plus facile que pour une lunette en acier.Of course, this depends on the material in which the bezel system is made. A plastic bezel that is hunted on the middle will be easier to remove than a steel bezel. This predisposition is the consequence of the fact that plastic has elastic properties that make it It is easier to deform than steel making it easier to assemble and disassemble a plastic bezel than for a steel bezel.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

La présente invention procède de l'idée générale inventive qui consiste à procurer un élément d'habillage pour carrure de pièce d'horlogerie facile à démonter.The present invention proceeds from the general inventive idea of providing a cladding element for the middle part of a timepiece that is easy to disassemble.

Une boîte 10 de pièce d'horlogerie comprend une carrure 20 fermée par un fond 60 et par une glace 40. Cette boite 10 comprend en outre l'élément d'habillage 30. Cet élément d'habillage 30 est fixé sur une zone de fixation de la carrure. Cet élément d'habillage 30 peut être un système de lunette 80 fixée à la carrure. Ce système de lunette 80 se présente sous la forme d'une pièce annulaire présentant une face supérieure et une face inférieure. La carrure 20 comprend un épaulement 2a dans lequel la lunette est placée. Cet épaulement 2a présente une paroi verticale 21, c'est-à-dire parallèle à l'axe central (C) de la carrure 20, et une paroi horizontale 22, c'est-à-dire perpendiculaire à l'axe central (C) de la carrure 20. La face supérieure de la pièce annulaire est la face visible par l'utilisateur, la face inférieure est la face en regard de la paroi horizontale 22 de la carrure. Une vue éclatée de la boîte 10 est visible à la figure 12.A timepiece box 10 comprises a middle part 20 closed by a bottom 60 and by an ice 40. This box 10 further comprises the covering element 30. This covering element 30 is fixed on a fixing zone of the middle part. This covering element 30 may be a telescope system 80 attached to the middle part. This bezel system 80 is in the form of an annular piece having an upper face and a lower face. The caseband 20 comprises a shoulder 2a in which the telescope is placed. This shoulder 2a has a vertical wall 21, that is to say parallel to the central axis (C) of the middle part 20, and a horizontal wall 22, that is to say perpendicular to the central axis ( C) of the middle part 20. The upper face of the annular piece is the face visible by the user, the lower face is the opposite face of the horizontal wall 22 of the middle part. An exploded view of the box 10 is visible at figure 12 .

Avantageusement, le système de lunette 80 visible à la figure 3 est une lunette 82 fixée à la carrure 20 de sorte à être facilement démontable. Pour cela, des moyens de fixation 70 sont agencés sur la carrure 20 et sur l'élément d'habillage 30, ici la lunette 82, pour que le démontage de ledit système de lunette 80 soit possible et simple.Advantageously, the telescope system 80 visible to the figure 3 is a bezel 82 attached to the middle part 20 so as to be easily removable. For this, fastening means 70 are arranged on the middle part 20 and on the covering element 30, here the bezel 82, so that the disassembly of said telescope system 80 is possible and simple.

Les moyens de fixation 70 comprennent une partie male 71 agencée sur la lunette 80 et une partie femelle 72 agencée sur la carrure 20. La partie male 71 est agencée sur la lunette 82 de préférence au niveau de la face inférieure 84 de. Cette partie male 71 se présente sous la forme d'au moins deux crochets 83 s'étendant depuis ladite face inférieure 84 c'est-à-dire de façon perpendiculaire au plan de la face inférieur 84. Ces crochets 83 sont composés d'une lame 86 s'étendant dans une direction verticale, perpendiculaire au plan de la face inférieure 84, et dont l'extrémité libre comprend une saillie 87. Cette saillie 87 s'étend dans une direction horizontale, c'est-à-dire parallèle au plan de la face inférieure 84 ou perpendiculaire par rapport à la lame, vers l'extérieure. On entend par là que cette saillie 87 s'étend dans une direction tendant à s'éloigner de l'axe central de la pièce annulaire qu'est la lunette 82.The attachment means 70 comprise a male portion 71 arranged on the bezel 80 and a female portion 72 arranged on the middle part 20. The male portion 71 is arranged on the bezel 82, preferably at the bottom face 84 of. This male portion 71 is in the form of at least two hooks 83 extending from said lower face 84, that is to say perpendicularly to the plane of the lower face 84. These hooks 83 are composed of a blade 86 extending in a vertical direction, perpendicular to the plane of the lower face 84, and whose free end comprises a projection 87. This projection 87 extends in a horizontal direction, that is to say parallel to the plane of the lower face 84 or perpendicular to the blade, to the outside. This means that this projection 87 extends in a direction tending to move away from the central axis of the annular piece that is the bezel 82.

La partie femelle 72 est agencée sur la carrure 20 et se présente, dans ce premier mode de réalisation, sous la forme de gorges 23, 203 dans laquelle un crochet 83 de la lunette 82. Le nombre de gorges 23, 203 est au moins égal au nombre de crochets 83 agencés sur la lunette 82. Cette gorge 23, 203 est agencée pour que, lorsque le crochet 83 est totalement engagé dedans, la saillie 87 dudit crochet 83 empêche la lunette d'être désolidarisée de la carrure 20. On comprendra qu'au moins deux crochets 83 sont nécessaires pour la fixation de la lunette 82.The female part 72 is arranged on the caseband 20 and is, in this first embodiment, in the form of grooves 23, 203 in which a hook 83 of the telescope 82. The number of grooves 23, 203 is at least equal to the number of hooks 83 arranged on the bezel 82. This groove 23, 203 is arranged so that, when the hook 83 is fully engaged in, the projection 87 of said hook 83 prevents the bezel from being detached from the middle part 20. It will be understood that at least two hooks 83 are necessary for fixing the telescope 82.

Dans une première alternative de la partie femelle 70 de la carrure 20 visible à la figure 3, celui-ci se présente sous la forme d'un rebord 24 situé sur la paroi horizontale 22 de l'épaulement. Ce rebord 24 s'étend perpendiculairement à la paroi horizontale 22 de l'épaulement et est périphérique. Ce rebord 24 présente une face intérieure et une face extérieure 24a. La face extérieure, la plus éloignée de l'axe central (C) de la carrure 20, comprend, à l'extrémité libre du rebord 24, une excroissance 25 parallèle à la paroi horizontale 22. Cette excroissance 25 permet de former un espace ouvert 27 entre ladite excroissance 25 et la paroi horizontale 22 de l'épaulement 2a. Cet espace est utilisé pour que la saillie 87 du crochet 83 puisse s'y insérer.In a first alternative of the female part 70 of the middle part 20 visible to the figure 3 , it is in the form of a flange 24 located on the horizontal wall 22 of the shoulder. This flange 24 extends perpendicularly to the horizontal wall 22 of the shoulder and is peripheral. This flange 24 has an inner face and an outer face 24a. The outer face, farthest from the central axis (C) of the caseband 20, comprises, at the free end of the rim 24, an outgrowth 25 parallel to the horizontal wall 22. This protrusion 25 makes it possible to form an open space 27 between said protrusion 25 and the horizontal wall 22 of the shoulder 2a. This space is used so that the projection 87 of the hook 83 can be inserted.

Dans une seconde alternative de la partie femelle 70 de la carrure 200 visible à la figure 4, la partie femelle 70 comprend une creusure 203a formant une gorge 203 située sur la paroi horizontale 202 de l'épaulement 2a. Cette gorge 203 présente un flanc intérieur et un flanc extérieur 204. A partir du flanc extérieur 204, le plus éloigné de l'axe central (C) de la carrure 20, s'étend une excroissance 205 permettant de former un espace ouvert 207 entre ladite excroissance 205 et la paroi horizontale 202 de l'épaulement 2a. Cet espace 207 est utilisé pour que la saillie 87 du crochet 83 puisse s'y insérer lorsque le crochet 87 est inséré dans la gorge 203.In a second alternative of the female part 70 of the middle part 200 visible at the figure 4 , the female part 70 comprises a recess 203a forming a groove 203 located on the horizontal wall 202 of the shoulder 2a. This groove 203 has an inner flank and an outer flank 204. From the outer flank 204, farthest from the central axis (C) of the middle part 20, extends an outgrowth 205 making it possible to form an open space 207 between said protrusion 205 and the horizontal wall 202 of the shoulder 2a. This space 207 is used so that the projection 87 of the hook 83 can be inserted therein when the hook 87 is inserted into the groove 203.

Lors du montage, la lunette 82 est placée dans l'épaulement de sorte que chaque crochet 87 soit placé en face d'une gorge 23, 203. Lorsqu'on exerce une pression sur la lunette 82 pour la fixer à la carrure 20, 200, les crochets 83 ont tendance à se déformer élastiquement pour entrer dans les gorges 23, 203. Lorsque la saillie 87 de chaque crochet 83 est en regard de l'espace 27, 207 entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 de l'épaulement, les crochets 83 reviennent dans leur position de repos et la saillie 87 de chaque crochet 83 entre dans ledit espace 27, 207. la coopération des crochets 83 avec l'espace entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 offre un maintien axial. La saillie 87 offre une surface de blocage venant prendre appui sur l'excroissance 25, 205 et bloquer la lunette 82 si l'utilisateur exerce une traction sur cette dernière. Ainsi, pour deux crochets 83 situés sur la lunette, la carrure 20, 200 comprend deux gorges 23, 203, ces crochets 83 et gorges 23, 203 étant agencés de sorte que la lunette 82 soit positionnée correctement c'est-à-dire que les sérigraphies sur la lunette comme les indications d'heure soient placés de façon correcte par rapport au cadran.During assembly, the telescope 82 is placed in the shoulder so that each hook 87 is placed in front of a groove 23, 203. When pressure is applied to the telescope 82 to fix it to the middle part 20, 200 the hooks 83 tend to deform elastically to enter the grooves 23, 203. When the projection 87 of each hook 83 is opposite the space 27, 207 between said protrusion 25, 205 and the horizontal wall 22, 202 of the shoulder, the hooks 83 return to their rest position and the projection 87 of each hook 83 enters said space 27, 207. the cooperation of the hooks 83 with the space between said protuberance 25, 205 and the horizontal wall 22 , 202 provides axial retention. The projection 87 provides a locking surface bearing on the protrusion 25, 205 and block the bezel 82 if the user exerts traction on the latter. Thus, for two hooks 83 located on the telescope, the middle part 20, 200 comprises two grooves 23, 203, these hooks 83 and grooves 23, 203 being arranged so that the bezel 82 is positioned correctly, that is to say that the serigraphs on the bezel as the time indications are placed correctly in relation to the dial.

Astucieusement selon l'invention, il est prévu que l'élément d'habillage 30 c'est-à-dire la lunette 82 puisse être facilement démontable. Pour cela, il est prévu que la carrure 20, 200 comprenne au moins une ouverture 26, 206 débouchant au niveau de la zone de fixation c'est à dire au niveau de la partie femelle. On comprend que ladite au moins une ouverture 26, 206 débouche dans l'espace 27, 207 présent entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 de l'épaulement. Cette ouverture 26, 206 est dimensionnée pour que l'utilisateur puisse y glisser un outil 90 pouvant être une lame ou une pointe comme visible aux figures 8 à 11. Cet outil 90 s'insère dans ladite ouverture 26, 206 de sorte à pouvoir faire pression sur la saillie 87 qui permet le maintien de ladite lunette 82 fixée à la carrure 20, 200 comme visible aux figures 8 à 11. Ainsi, lorsque l'utilisateur glisse l'outil 90 dans l'ouverture 26, 206 jusqu'à entrer en contact avec ladite saillie 87. Il exerce alors une pression sur la saillie 87 via son outil 90 de sorte que le crochet 83 se déforme et que la saillie 87 dudit crochet sorte de l'espace 27, 207 présent entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 de l'épaulement comme visible à la figure 10. Il devient alors possible pour l'utilisateur de soulever la lunette pour sortir l'un des crochets 83 de la gorge 23, 203 comme visible à la figure 11. L'utilisateur peut ensuite manipulée la lunette 83 pour désengager l'autre crochet 83 de la gorge 23, 203 avec laquelle il coopère.Cleverly according to the invention, it is expected that the covering element 30 that is to say the bezel 82 can be easily removable. For this, it is expected that the middle part 20, 200 comprises at least one opening 26, 206 opening at the attachment zone that is to say at the female part. It is understood that said at least one opening 26, 206 opens into the space 27, 207 present between said protrusion 25, 205 and the horizontal wall 22, 202 of the shoulder. This opening 26, 206 is dimensioned so that the user can slide a tool 90 that can be a blade or a tip as visible to Figures 8 to 11 . This tool 90 fits into said opening 26, 206 so as to be able to press the projection 87 which allows the maintenance of said bezel 82 fixed to the middle part 20, 200 as visible to the Figures 8 to 11 . Thus, when the user slides the tool 90 in the opening 26, 206 until it comes into contact with said projection 87. It then exerts pressure on the projection 87 via its tool 90 so that the hook 83 is deformed and that the projection 87 of said hook comes out of the space 27, 207 present between said protuberance 25, 205 and the horizontal wall 22, 202 of the shoulder as visible in FIG. figure 10 . It then becomes possible for the user to lift the telescope to release one of the hooks 83 of the groove 23, 203 as visible in FIG. figure 11 . The user can then manipulate the bezel 83 to disengage the other hook 83 of the groove 23, 203 with which it cooperates.

De préférence, la carrure 20, 200 comprend deux ouvertures 26, 206 agencées pour qu'un outil 90 à deux pointes puisse être utilisé. En effet, si le crochet 83 présente une largeur importante, le fait d'exercer une force en un point unique présente le risque de voir ledit crochet 83 se déformer uniquement à l'endroit où la pression est exercée. La force exercée risque donc de ne pas être suffisante pour provoquer le désengagement de la saillie 87 de l'espace 27, 207 présent entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 de l'épaulement. Le fait d'avoir une pièce configurée avec deux pointes permet de mieux répartir les forces exercées par l'outil sur la saillie 87 et donc le crochet 83. Cela permet d'avoir deux points de contacts avec la saillie 87 et donc de déformer élastiquement ledit crochet 83 de façon plus efficace.Preferably, middle part 20, 200 comprises two openings 26, 206 arranged for a two-point tool 90 can be used. Indeed, if the hook 83 has a large width, the fact of exerting a force at a single point has the risk of seeing said hook 83 deform only at the point where the pressure is exerted. The force exercised risk therefore not to be sufficient to cause the disengagement of the projection 87 of the space 27, 207 present between said protrusion 25, 205 and the horizontal wall 22, 202 of the shoulder. The fact of having a configured part with two tips makes it possible to better distribute the forces exerted by the tool on the projection 87 and therefore the hook 83. This makes it possible to have two points of contact with the projection 87 and thus to deform elastically said hook 83 more effectively.

Dans une première variante de ce premier mode de réalisation, la partie mâle 71 des moyens de fixation 70 comprennent plusieurs lames 86 disposés sur un cercle virtuel 86a comme visible à la figure 5. La partie mâle 71 est agencée pour que certaines lames 86 présentent une saillie 87 s'étendant dans une direction tendant à s'éloigner du centre du cercle virtuel 86a. La partie femelle 72 située sur la carrure 20, 200 se présente sous la forme d'une gorge 23, 203 formant un cercle identique au cercle virtuel 86a. Cette gorge 23, 203 peut être agencée pour reprendre le principe de la première version ou de la seconde version du système d'accrochage. La partie male 71 de la lunette 82 peut alors coopérer avec la partie femelle 72 de la carrure 20, 200. Cette configuration permet également de simplifier le montage car la lunette 82 peut être montée sans orientation spécifique par rapport à la carrure 20, 200. L'intérêt d'une telle configuration est de permettre à la lunette 82 de tourner par rapport à la carrure, la partie male se déplaçant le long de la gorge faisant ici office de rail. Des moyens de crantage et des moyens ressorts sont alors agencés au niveau de la carrure pour permettre de contrôler la rotation de la lunette.In a first variant of this first embodiment, the male portion 71 of the fastening means 70 comprises a plurality of blades 86 arranged on a virtual circle 86a as visible in FIG. figure 5 . The male portion 71 is arranged so that some blades 86 have a protrusion 87 extending in a direction tending to move away from the center of the virtual circle 86a. The female portion 72 located on the middle part 20, 200 is in the form of a groove 23, 203 forming a circle identical to the virtual circle 86a. This groove 23, 203 may be arranged to take the principle of the first version or the second version of the attachment system. The male part 71 of the telescope 82 can then cooperate with the female part 72 of the middle part 20, 200. This configuration also makes it possible to simplify the assembly because the telescope 82 can be mounted without specific orientation with respect to the caseband 20, 200. The advantage of such a configuration is to allow the bezel 82 to rotate relative to the middle part, the male part moving along the groove here rail office. Locking means and spring means are then arranged at the middle to allow to control the rotation of the bezel.

Un autre avantage est que la partie mâle peut, en outre, présenter des lames 86 ne présentant pas de saillie 87. Ces lames 86 font office de maintien radial.Another advantage is that the male part may, in addition, have blades 86 having no protrusion 87. These blades 86 act as radial support.

Avantageusement, cette variante, visible à la figure 5, est configurée pour que la partie male 71 comprenne deux lames 86 présentant une saillie 87. Ces lames 86 sont préférentiellement diamétralement opposées, une première lame 88 s'étend angulairement selon un premier angle al d'environ 20° alors que la seconde lame 89 s'étend selon un second angle a2, supérieur au premier angle, d'environ 120°. Cette configuration particulière permet d'avoir un meilleur maintien axial. Effectivement, le maintien axial de la lunette 82 sur la carrure 20, 200 est réalisé par les saillies 87 des crochets 83 qui coopère avec la gorge 23, 203 comme expliqué auparavant. Or, si les deux lames 86 s'étendaient angulairement sur un faible angle, le maintien axial serait assuré mais il existe un risque qu'une forte traction sur la lunette 82 puisse l'arracher de la carrure 20, 200 tout en l'endommageant. En effet, la force de traction serait appliquée sur une faible surface entraînant une forte contrainte sur les lames 86 présentant une saillie 87 et donc un risque de rupture important. Avec la configuration proposée, le maintien axial est amélioré car la partie male 71 possède une surface de blocage plus importante. De ce fait, la contrainte exercée lors de la traction est répartie sur une surface plus importante et les contraintes appliquées sur les saillies 87 sont moindres.Advantageously, this variant, visible at the figure 5 , is configured so that the male portion 71 comprises two blades 86 having a projection 87. These blades 86 are preferably diametrically opposed, a first blade 88 extends angularly at a first angle α of about 20 ° while the second blade 89 extends at a second angle a2, greater than the first angle, of about 120 °. This particular configuration allows for better axial retention. Indeed, the axial retention of the telescope 82 on the middle part 20, 200 is achieved by the projections 87 of the hooks 83 which cooperates with the groove 23, 203 as explained above. However, if the two blades 86 extended angularly at a small angle, axial retention would be ensured but there is a risk that a strong pull on the telescope 82 can tear it from the middle part 20, 200 while damaging it . Indeed, the tensile force would be applied to a small surface causing a high stress on the blades 86 having a projection 87 and therefore a significant risk of rupture. With the proposed configuration, the axial retention is improved because the male portion 71 has a larger locking surface. As a result, the stress exerted during the traction is distributed over a larger area and the stresses applied to the projections 87 are smaller.

De plus, cette configuration est réalisée pour que la première lame 86 qui s'étend angulairement sur un faible angle soit celle que l'utilisateur manipule pour désengager la lunette 82 de la carrure 20, 200. En effet, lorsque l'utilisateur veut désengager la lunette 82 de la carrure 20, 200, il agit sur la lunette 82 de sorte que cette première lame 86 vienne en regard de la au moins une ouverture 26, 206 débouchant dans l'espace 27, 207 présent entre ladite excroissance 25, 205 et la paroi horizontale 22, 202 de l'épaulement. Cela permet à l'utilisateur d'utiliser son outil 90 pour agir sur la première lame 86 et ainsi dégager la lunette 82 de la carrure 20, 200. Le fait d'avoir deux lames 86 avec saillie 87 disposées de façon diamétralement opposées et une des lames s'étendant angulairement de façon plus importante que l'autre permet d'avoir une lunette 82 qui est bien maintenu à la carrure 20, 200 tout en étant facilement détachable. Néanmoins, il ne faut pas que la lame qui s'étend angulairement de la façon la plus importante dépasse un certain angle.In addition, this configuration is performed so that the first blade 86 which extends angularly at a low angle is that which the user manipulates to disengage the telescope 82 of the middle part 20, 200. Indeed, when the user wants to disengage the bezel 82 of the middle part 20, 200, it acts on the bezel 82 so that this first blade 86 comes opposite the at least one opening 26, 206 opening into the space 27, 207 present between said outgrowth 25, 205 and the horizontal wall 22, 202 of the shoulder. This allows the user to use his tool 90 to act on the first blade 86 and thus release the bezel 82 of the middle part 20, 200. The fact of having two blades 86 with projection 87 arranged diametrically opposite and a blades extending angularly more than the other allows to have a telescope 82 which is well held at the middle 20, 200 while being easily detachable. Nevertheless, the blade that extends angularly in the most important way must not exceed a certain angle.

Dans une seconde variante de ce premier mode de réalisation, le système de lunette 800, visible aux figures 6a et 6b, est composée de plusieurs éléments. On comprend alors que le système de lunette 800 comprenant une bague de prémontage 812 présentant une face inférieure 812b et une face supérieure 812a. Sur la face supérieure 812a de la bague de prémontage 812 sont agencés des moyens ressorts 810, des moyens de crantage 811 et une bague de lunette 809, cette dernière étant la partie visible par l'utilisateur. Les moyens ressorts 810 et les moyens de crantage 811 sont agencés de sorte que les moyens ressorts 810 soient angulairement solidaires de la carrure 20, 200, les moyens de crantage 811 étant angulairement solidaires de la bague de prémontage 812 et de la bague lunette 809. Il se peut que les moyens ressorts 810 soient angulairement solidaires de la bague de prémontage 812 et de la bague lunette 809, les moyens de crantage 811 étant angulairement solidaires de la carrure 20, 200. Sur la face inférieure 812b de la bague de prémontage 812 est agencée la partie mâle 71 des moyens de fixation 70. Cette variante à l'avantage de permettre d'avoir un système de lunette 800 sous la forme d'un module indépendant qui peut être fixé à la carrure 20, 200 ou détaché de la carrure 20, 200 d'un seul bloc.In a second variant of this first embodiment, the telescope system 800, visible to Figures 6a and 6b , is composed of several elements. It is then understood that the bezel system 800 comprising a pre-assembly ring 812 having a lower face 812b and an upper face 812a. On the upper face 812a of the pre-assembly ring 812 are arranged spring means 810, notching means 811 and a bezel ring 809, the latter being the visible part by the user. The spring means 810 and the notching means 811 are arranged so that the spring means 810 are angularly integral with the middle part 20, 200, the notching means 811 being angularly integral with the pre-assembly ring 812 and the bezel ring 809. It may be that the spring means 810 are angularly integral with the pre-assembly ring 812 and the bezel ring 809, the notching means 811 being angularly integral with the middle part 20, 200. On the lower face 812b of the pre-assembly ring 812 is arranged the male portion 71 of the fastening means 70. This variant has the advantage of allowing to have a telescope system 800 in the form of an independent module which can be fixed to the middle part 20, 200 or detached from the middle part 20, 200 of a single block.

Dans un second mode de réalisation visible à la figure 7, l'élément d'habillage 30 est le fond 60 fixé à la carrure 2000. En effet, que ce soit dans une pièce d'horlogerie mécanique ou une pièce d'horlogerie électronique, il peut être utile d'avoir un fond 60 amovible. Cette possibilité de fond 60 amovible permet d'avoir facilement accès au mouvement de la montre. l'entretien du mouvement, le remplacement de pièce ou le changement de pile peuvent donc être effectués aisément.In a second embodiment visible at the figure 7 , the covering element 30 is the bottom 60 fixed to the middle of 2000. Indeed, whether in a mechanical timepiece or an electronic timepiece, it may be useful to have a removable bottom 60 . This possibility of removable background 60 allows easy access to the movement of the watch. Motion maintenance, part replacement or battery change can therefore be done easily.

La carrure 2000 comprend une face inférieure sur laquelle ledit fond 60 est fixé. De préférence la carrure 2000 et le fond 60 ont une forme sensiblement similaire pour des questions d'esthétisme. La face inférieure de la carrure 2000 comprend la partie femelle 72 des moyens de fixation 70 de sorte que la partie male 71, agencé sur le fond 60, puisse coopérer.The middle part 2000 comprises a lower face on which said bottom 60 is fixed. Preferably the middle part 2000 and the base 60 have a substantially similar shape for aesthetic reasons. The underside of the middle part 2000 includes the female part 72 of the fastening means 70 so that the male portion 71, arranged on the bottom 60, can cooperate.

Il est également possible que la face inférieure de la carrure présente un épaulement similaire à celui décrit pour le premier mode de réalisation. L'élément d'habillage se présente ici sous la forme d'un couvercle venant fermer la carrure. Les caractéristiques du premier mode de réalisation et de ses variantes et versions peuvent être appliqués pour ce second mode de réalisation.It is also possible that the lower face of the case has a shoulder similar to that described for the first embodiment. The dressing element is here in the form of a lid that closes the middle part. The features of the first embodiment and its variants and versions can be applied for this second embodiment.

L'étanchéité de cet élément d'habillage agencé comme fond de la carrure peut être amélioré en installant un joint d'étanchéité au niveau dudit élément d'habillage.The tightness of this covering element arranged as the bottom of the middle part can be improved by installing a seal at the level of said covering element.
