Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un outil destiné à aider un horloger à séparer un fond d'une carrure d'une pièce d'horlogerie, de même qu'un tel fond présentant un dégagement adapté pour recevoir l'outil et une pièce d'horlogerie équipée d'un tel fond.The present invention relates to a tool intended to help a watchmaker to separate a caseback from a middle part of a timepiece, as well as such a caseback having a clearance adapted to receive the tool and a timepiece equipped from such a background.

Arrière-plan technologique de l'inventionTechnological background of the invention

Lorsqu'une montre revient en usine, par exemple pour y être révisée ou y être réparée, il est nécessaire d'ouvrir le fond de cette montre. Mais l'opération consistant à ouvrir le fond d'une boîte de montre est toujours une opération délicate qui demande beaucoup de soin de la part de l'horloger effectuant une telle intervention. La catégorie de fonds auxquels s'intéresse la présente invention est celle qui regroupe les fonds montés sur la carrure par emboîtement avec interposition d'un joint d'étanchéité entre le fond et la carrure. Pour permettre leur ouverture, de tels fonds présentent classiquement en un endroit de leur bord périphérique extérieur un dégagement qui permet à l'horloger d'introduire un outil entre ce fond et la carrure sur laquelle ce fond est fixé. Pour ensuite séparer le fond de la carrure, deux techniques sont possibles : soit l'horloger engage l'outil dans le dégagement et fait tourner cet outil sur lui-même, de sorte que, par effet de levier, il est possible de séparer progressivement le fond de la carrure ; soit l'horloger pousse plusieurs fois l'outil en avant et engage progressivement ce dernier entre le fond et la carrure, se servant alors de l'outil à la façon d'un coin pour séparer le fond de la carrure. Quelle que soit la technique choisie par l'horloger pour séparer le fond de la carrure, et malgré tout le soin apporté par l'horloger pour effectuer cette opération, il est fréquent que le fond ressorte marqué de son opération de démontage. En effet, à l'heure actuelle, le dégagement ménagé sur le fond pour permettre d'engager l'outil et de séparer le fond de la carrure est agencé de sorte que, très souvent, lorsqu'on engage l'outil, cela blesse le bord périphérique extérieur du fond et laisse une marque parfaitement visible à l'œil nu une fois le fond remonté. Bien entendu, il n'est pas envisageable de rendre après révision à son propriétaire une montre qui a été abîmée. Par conséquent, lorsque ce genre de problème surgit, on est soit obligé de reprendre le fond pour faire disparaître la marque -cette opération est appelée opération de « rhabillage » dans le domaine de l'horlogerie-, soit on doit procéder au remplacement du fond. Dans les deux cas, cela entraîne un surcoût que l'on ne peut bien sûr pas imputer au propriétaire de la montre. Ce problème sera mieux compris à l'examen de la figure 1 annexée à la présente demande de brevet qui est une vue partielle en coupe d'une boîte de montre dans la région où est prévu un dégagement conforme à l'art antérieur permettant à un horloger d'introduire un outil à l'aide duquel il va séparer le fond de la carrure. Désignée dans son ensemble par la référence numérique générale 1, la boîte de montre comprend une carrure 2 à la base de laquelle est emboîté un fond 4 avec interposition d'un joint d'étanchéité 6 entre ce fond 4 et cette carrure 2. En un endroit de son périmètre, le fond 4 présente un dégagement 8 qui libère, entre ce fond 4 et la carrure 2, un espace 10 permettant à l'horloger d'engager l'extrémité d'un outil 12 à l'aide duquel l'horloger va exercer sur le fond 4 un bras de levier pour séparer ce fond 4 de la carrure 2.When a watch returns to the factory, for example to be serviced or repaired there, it is necessary to open the back of this watch. But the operation consisting in opening the back of a watch case is always a delicate operation which requires a great deal of care on the part of the watchmaker carrying out such an intervention. The category of backs with which the present invention is concerned is that which includes the backs mounted on the caseband by interlocking with the interposition of a seal between the caseback and the caseband. To allow them to be opened, such backs conventionally have, at a location on their outer peripheral edge, a clearance which allows the watchmaker to introduce a tool between this back and the caseband to which this back is fixed. To then separate the caseback from the middle, two techniques are possible: either the watchmaker engages the tool in the clearance and rotates this tool on itself, so that, by leverage, it is possible to gradually separate the case back; or the watchmaker pushes the tool forward several times and gradually engages the latter between the back and the caseband, then using the tool like a wedge to separate the caseback from the caseband. Whichever technique is chosen by the watchmaker to separate the caseback from the middle, and despite all the care taken by the watchmaker to carry out this operation, it is common for the caseback to emerge marked from its dismantling operation. Indeed, at the present time, the clearance provided on the back to allow the tool to be engaged and to separate the back from the caseband is arranged so that, very often, when the tool is engaged, this injures the outer peripheral edge of the caseback and leaves a mark perfectly visible to the naked eye once the caseback has been raised. Of course, it is not possible to return a damaged watch to its owner after servicing. Consequently, when this type of problem arises, one is either obliged to redo the caseback to make the mark disappear - this operation is called an operation of "redressing" in the field of watchmaking-, or one must replace the caseback. . In both cases, this entails an additional cost which of course cannot be attributed to the owner of the watch. This problem will be better understood by examining the figure 1 annexed to the present patent application which is a partial sectional view of a watch case in the region where there is provided a release in accordance with the prior art enabling a watchmaker to introduce a tool with the aid of which he will separate the back from the middle. Designated as a whole by the general reference numeral 1, the watch case comprises a middle part 2 at the base of which is fitted a back 4 with the interposition of a seal 6 between this bottom 4 and this middle part 2. In one location of its perimeter, the back 4 has a clearance 8 which releases, between this back 4 and the middle part 2, a space 10 allowing the watchmaker to engage the end of a tool 12 with the aid of which the watchmaker will exert on the back 4 a lever arm to separate this back 4 from the caseband 2.

Dans ce qui suit, on qualifiera un plan ou une surface d' « horizontal » quand ce plan ou cette surface s'étend dans un plan parallèle au plan P moyen dans lequel s'étend un mouvement d'horlogerie 14 qui est logé dans la boîte de montre 1. On parle de plan « moyen » P uniquement parce que le mouvement d'horlogerie 14 présente une épaisseur qui ne peut être réduite à un plan unique. Comme on peut le constater en examinant la figure 1, l'outil 12 a l'aspect d'un coin, c'est-à-dire une pièce de forme aigüe formée d'une première face 12a et d'une seconde face 12b qui se coupent selon un angle α inférieur à 90° et qui se raccordent l'une à l'autre par une portion arrondie 12c. Quant au dégagement 8 ménagé dans le fond 4, il se présente sous la forme d'une surface 8a inclinée par rapport à l'horizontale lorsque le fond 4 est fixé sur la carrure 2. Cette surface inclinée 8a s'éloigne de la carrure 2 vers le bas de cette dernière et est prolongée par une portion arrondie 8b assurant le raccordement entre la surface inclinée 8a et une surface inférieure 16 du fond 4. Comme il ressort de la figure 1, la portion arrondie 8b forme un bord extérieur 18 du fond 4.In what follows, a plane or a surface will be qualified as "horizontal" when this plane or this surface extends in a plane parallel to the mean plane P in which extends a clock movement 14 which is housed in the watch case 1. We speak of a “medium” plane P only because the watch movement 14 has a thickness which cannot be reduced to a single plane. As can be seen by examining the figure 1 , the tool 12 has the appearance of a wedge, that is to say a piece of acute shape formed of a first face 12a and a second face 12b which intersect at an angle α of less than 90° and which are connected to each other by a rounded portion 12c. As for the clearance 8 provided in the back 4, it is in the form of a surface 8a inclined with respect to the horizontal when the back 4 is fixed to the caseband 2. This inclined surface 8a moves away from the caseband 2 towards the bottom of the latter and is extended by a rounded portion 8b ensuring the connection between the inclined surface 8a and a lower surface 16 of the bottom 4. As emerges from the figure 1 , the rounded portion 8b forms an outer edge 18 of the bottom 4.

On voit sur la figure 1 que, pour séparer le fond 4 de la carrure 2, l'outil 12 est engagé dans le dégagement 8 en étant orienté de sorte que sa première face 12a s'étende horizontalement, c'est-à-dire parallèlement au plan moyen P dans lequel s'étend le mouvement d'horlogerie 14. On voit aussi sur cette figure 1 que lorsque l'horloger engage l'outil 12 dans l'espace 10 libéré entre la carrure 2 et le fond 4 par le dégagement 8, l'outil 12 vient en appui sur le bord extérieur 18 du fond 4 par sa seconde face 12b. Par conséquent, si, pour réussir à séparer le fond 4 de la carrure 2, l'horloger est obligé d'exercer avec l'outil 12 une force de levier un peu trop importante, il risque de blesser le bord extérieur 18 du fond 4 et de laisser une marque 19 bien visible dans la zone où l'outil 12 vient en appui sur le bord extérieur 18 du fond 4. Bien entendu, l'horloger ne pourra pas rendre la montre à son propriétaire dans cet état et devra soit ré-usiner le fond 4 pour faire disparaître la marque 19, soit se procurer un nouveau fond en remplacement de celui qui a été abîmé. Dans les deux cas, cela représente une perte de temps et d'argent pour le fabricant horloger.We see on the figure 1 that, to separate the back 4 from the middle part 2, the tool 12 is engaged in the recess 8 while being oriented so that its first face 12a extends horizontally, that is to say parallel to the mean plane P in which extends the clock movement 14. We also see on this figure 1 that when the watchmaker engages the tool 12 in the space 10 released between the caseband 2 and the back 4 by the clearance 8, the tool 12 comes to rest on the outer edge 18 of the back 4 by its second face 12b. Consequently, if, in order to successfully separate the back 4 from the caseband 2, the watchmaker is obliged to exert a little too much leverage with the tool 12, he risks injuring the outer edge 18 of the back 4 and to leave a clearly visible mark 19 in the area where the tool 12 bears against the outer edge 18 of the bottom 4. Of course, the watchmaker will not be able to return the watch to its owner in this state and will have to either -machine bottom 4 to remove mark 19, or obtain a new bottom to replace the damaged one. In both cases, this represents a waste of time and money for the watch manufacturer.

Résumé de l'inventionSummary of the invention

La présente invention a pour objet de procurer un outil ainsi qu'un nouvel agencement pour un fond d'une boîte de montre qui permet de garantir qu'au cas où le fond est marqué par l'outil lorsque l'horloger sépare le fond de la carrure de la boîte de montre, cette marque ne sera pas perceptible par le propriétaire de la montre.The object of the present invention is to provide a tool as well as a new arrangement for a bottom of a watch case which makes it possible to guarantee that in the event that the caseback is marked by the tool when the watchmaker separates the caseback from the middle part of the watch case, this mark will not be perceptible to the owner of the watch.

Description détaillée d'un mode de réalisation de l'inventionDetailed description of an embodiment of the invention

La présente invention procède de l'idée générale inventive qui consiste à procurer aux horlogers un outil leur permettant de séparer le fond d'une carrure d'une boîte de montre sans laisser sur le fond de marque visible par le propriétaire de la montre après remontage du fond sur la carrure. La présente invention concerne également un fond de boîte de montre qui présente un dégagement dont le profil est agencé de façon que si, malgré tout le soin apporté par l'horloger lorsqu'il sépare le fond de la carrure de la boîte de montre, le fond ressort marqué de cette opération de démontage, la marque laissée par l'outil sur le fond ne sera pas visible par le propriétaire de la montre une fois le fond remonté sur la carrure.The present invention proceeds from the inventive general idea which consists in providing watchmakers with a tool enabling them to separate the back of a caseband from a watch case without leaving a mark on the bottom visible to the owner of the watch after reassembly. from the back to the middle. The present invention also relates to a watch case back which has a clearance whose profile is arranged so that if, despite all the care taken by the watchmaker when separating the back from the middle of the watch case, the spring back marked by this dismantling operation, the mark left by the tool on the back will not be visible to the owner of the watch once the back is reassembled on the caseband.

Comme visible sur la figure 2A, un outil 20 conforme à l'invention a l'aspect d'un coin, c'est-à-dire d'une pièce de forme aigüe formée d'une première face 20a et d'une seconde face 20b qui se coupent selon un angle α inférieur à 90° et qui se raccordent l'une à l'autre par une portion arrondie 20c. Plus précisément, la portion arrondie 20c se raccorde à la seconde face 20b de l'outil 20 par une portion courbe 20d dont la courbure est dirigée vers l'intérieur d'une surface 20e de l'outil 20 délimitée par les première et seconde faces 20a, 20b.As seen on the figure 2A , a tool 20 in accordance with the invention has the appearance of a wedge, that is to say of a piece of acute shape formed of a first face 20a and a second face 20b which intersect along an angle α less than 90° and which are connected to each other by a rounded portion 20c. More specifically, the rounded portion 20c connects to the second face 20b of the tool 20 by a curved portion 20d whose curvature is directed towards the inside of a surface 20e of the tool 20 delimited by the first and second faces 20a, 20b.

Comme on le comprendra mieux par la suite, l'outil 20 est destiné à être utilisé par un horloger pour séparer un fond 22 d'une carrure 24 qui ensemble délimitent une boîte de montre 26 d'une pièce d'horlogerie 28 à l'intérieur de laquelle est logé un mouvement d'horlogerie 30. Plus précisément, la première face 20a de l'outil 20 est agencée de sorte que, lorsque l'horloger engage l'outil 20 entre le fond 22 et la carrure 24 afin de séparer ce fond 22 de cette carrure 24, cette première face 20a s'étend parallèlement à un plan moyen P dans lequel se trouve le mouvement d'horlogerie 30.As will be better understood subsequently, the tool 20 is intended to be used by a watchmaker to separate a back 22 from a middle part 24 which together delimit a watch case 26 from a timepiece 28 at the inside which a clockwork movement 30 is housed. More specifically, the first face 20a of the tool 20 is arranged so that, when the watchmaker engages the tool 20 between the back 22 and the middle part 24 in order to separate this bottom 22 of this middle part 24, this first face 20a extends parallel to a mean plane P in which the clock movement 30 is located.

Toujours selon l'invention, le fond 22 de la pièce d'horlogerie 28 est délimité extérieurement par un périmètre en un endroit au moins duquel est ménagé un dégagement 32 qui libère, entre ce fond 22 et la carrure 24, un espace 34 permettant à l'horloger d'engager l'extrémité de l'outil 20 à l'aide duquel l'horloger va exercer sur le fond 22 un bras de levier pour séparer ce fond 22 de la carrure 24. Pour permettre l'engagement de l'outil 20, le dégagement 32 comprend une première surface plane 32a parallèle au plan moyen P dans lequel s'étend le mouvement d'horlogerie 30, cette première surface plane 32a étant prolongée, via une première portion arrondie 32c, par une seconde surface plane inclinée 32b qui forme avec le plan moyen P un angle aigu β lorsque le fond 22 est fixé sur la carrure 24. Cette seconde surface plane inclinée 32b s'éloigne de la carrure 24 vers le bas de cette dernière et est prolongée par une portion 32d par exemple arrondie qui assure le raccordement entre la seconde surface plane inclinée 32b et une surface inférieure 36 du fond 22.Still according to the invention, the back 22 of the timepiece 28 is delimited on the outside by a perimeter at one place at least of which is made a clearance 32 which releases, between this back 22 and the middle part 24, a space 34 allowing the watchmaker to engage the end of the tool 20 with the aid of which the watchmaker will exert on the back 22 a lever arm to separate this back 22 from the middle part 24. To allow the engagement of the tool 20, clearance 32 comprises a first flat surface 32a parallel to the mean plane P in which extends the clock movement 30, this first flat surface 32a being extended, via a first rounded portion 32c, by a second inclined flat surface 32b which forms with the mean plane P an acute angle β when the bottom 22 is fixed on the caseband 24. This second inclined flat surface 32b moves away from the caseband 24 towards the bottom of the latter and is extended by a portion 32d by rounded example that provides the connection between the sec wave flat inclined surface 32b and a lower surface 36 of the bottom 22.

Pour faciliter l'engagement de l'outil 20 dans le dégagement 32, l'angle α entre la première face 20a et la seconde face 20b de l'outil 20 est inférieur à l'angle aigu β que forme la seconde surface inclinée 32b avec le plan moyen P, ce qui permet à l'outil 20 de venir en appui par sa portion courbe 20d dans une zone 38 de la première portion arrondie 32c du dégagement 32 qui ne sera pas perceptible par le propriétaire de la pièce d'horlogerie 28 une fois le fond 22 à nouveau fixé sur la carrure 24. Par conséquent, même si la zone 38 est marquée par l'opération de séparation du fond 22 et de la carrure 24, cette marque ne sera plus visible lorsque le fond 22 sera remonté.To facilitate the engagement of the tool 20 in the clearance 32, the angle α between the first face 20a and the second face 20b of the tool 20 is less than the acute angle β that the second inclined surface 32b forms with the mean plane P , which allows the tool 20 to come to rest by its curved portion 20d in a zone 38 of the first rounded portion 32c of the clearance 32 which will not be perceptible by the owner of the timepiece 28 a once the bottom 22 is fixed again on the caseband 24. Consequently, even if the zone 38 is marked by the operation of separating the caseback 22 and the caseband 24, this mark will no longer be visible when the caseback 22 is reassembled.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various simple modifications and variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined. by the appended claims.
