Elastic means (9) are also provided for returning the flange (6) in the direction of the cover (3) so as to hold the stake (7) jammed in the aperture in the plate-shaped part.

Description

Boîte protectrice pour le transport ou le stockage d'une pièce avant la forme d'une plaque percée d'une ouverture Protective box for transporting or storing a workpiece before the form of a plate pierced with an opening
La présente invention concerne une boîte protectrice pour le transport ou le stockage d'une pièce ayant la forme d'une pièce plane, ou plaque, percée d'une ouverture ; par exemple un cadran de montre. La présente invention concerne plus particulièrement une telle boîte comportant un dispositif de serrage prévu pour s'étendre dans l'ouverture de la plaque de façon à retenir la plaque. La présente invention concerne notamment une telle boîte prévue pour contenir un cadran de montre.The present invention relates to a protective box for transporting or storing a workpiece in the form of a flat part, or plate, pierced with an opening; for example a watch dial. The present invention relates more particularly to such a box comprising a clamping device intended to extend into the opening of the plate so as to retain the plate. The present invention relates in particular to such a box designed to contain a watch face.
Un but de la présente invention est de fournir une boîte dont la conception minimise les conséquences néfastes que pourrait avoir une manipulation maladroite ou erronée. En particulier, un but est de fournir une boîte conçue pour que la force avec laquelle on presse sur le couvercle n'influence pas la force de maintien de la pièce en forme de plaque.An object of the present invention is to provide a box whose design minimizes the harmful consequences that could have an awkward or wrong handling. In particular, an object is to provide a box designed so that the force with which one presses on the lid does not influence the holding force of the plate-shaped part.
Un autre but est de fournir une boîte prévue pour supporter des chocs accidentels de 5000 g (chute de un mètre sur du bois dur) sans pour autant que le contenu ou la boîte ne subisse quoi que ce soit comme dégâts.Another goal is to provide a box designed to withstand accidental shocks of 5000 g (falling one meter on hardwood) without the content or the box experiencing anything as damage.
Un autre but de la présente invention est de fournir une boîte pouvant accomoder la gamme la plus large possible de pièces de dimensions différentes (diamètre, épaisseur, diamètre de l'ouverture, etc).Another object of the present invention is to provide a box that can accommodate the widest possible range of pieces of different dimensions (diameter, thickness, diameter of the opening, etc.).
Un autre but de la présente invention est de fournir une gamme de boîtes ne se distinguant les unes des autres que par les dimensions du dispositif de serrage qui peut être adapté aux dimensions particulières d'un modèle de pièces.Another object of the present invention is to provide a range of boxes distinguished from each other only by the dimensions of the clamping device which can be adapted to the particular dimensions of a model parts.
Un autre but de la présente invention est de fournir une boite avec laquelle l'introduction et l'extraction d'une pièce est aisée.Another object of the present invention is to provide a box with which the introduction and extraction of a part is easy.
Un autre but de la présente invention est de fournir une boîte dont le coût unitaire est réduit.Another object of the present invention is to provide a box whose unit cost is reduced.
La présente invention atteint ces buts en fournissant une boîte, pour le transport et le stockage d'une pièce ayant la forme d'une plaque percée d'une ouverture, conforme à la revendication 1 annexée.The present invention achieves these objects by providing a box for transporting and storing a workpiece in the form of a plate pierced with an opening according to the appended claim 1.
Selon la présente invention, le tasseau est monté fixe sur la flasque, et la flasque est elle-même retenue par des moyens élastiques prévus pour la rappeler en direction du couvercle. Dans ces conditions, lorsque la boîte est fermée, la force exercée par la saillie sur le tasseau est toujours égale à la force de rappel fournie par les moyens élastiques. Ainsi, la force avec laquelle on presse sur le couvercle n'influence pas la force exercée sur le tasseau. Un avantantge de la présente invention est donc que la présence des moyens élastiques permet de ne pas endommager le tasseau.According to the present invention, the cleat is fixedly mounted on the flange, and the flange is itself retained by resilient means provided to recall it towards the cover. Under these conditions, when the box is closed, the force exerted by the projection on the cleat is always equal to the restoring force provided by the elastic means. Thus, the force with which one presses on the lid does not influence the force exerted on the cleat. An advantage of the present invention is therefore that the presence of elastic means makes it possible not to damage the cleat.
Un autre avantage de la présente invention est d'éviter que, sous l'effet d'une trop forte pression, le tasseau n'endommage le cadran.Another advantage of the present invention is to avoid that, under the effect of too much pressure, the cleat does not damage the dial.
Un autre avantage de la présente invention est que seul la flasque et le tasseau entrent en contact avec le cadran. Les parties fonctionnelles du cadran, qui sont situées sur sa face supérieure, n'ont donc jamais à entrer en contact avec les différentes parties de la boîte.Another advantage of the present invention is that only the flange and the cleat come into contact with the dial. The functional parts of the dial, which are located on its upper face, therefore never have to come into contact with the different parts of the box.
Un autre avantage est que la flasque retenue élastiquement permet d'utiliser la même boîte avec des cadrans ayant des épaisseurs différentes.Another advantage is that the elastically retained flange allows the same box to be used with dials having different thicknesses.
Selon la présente invention, les moyens élastiques doivent rappeler la flasque en direction du couvercle avec suffisamment de force pour maintenir le tasseau calé dans l'ouverture de la pièce en forme de plaque. Cela revient à dire que, pour maintenir le tasseau calé dans l'ouverture de la plaque, il est nécessaire que celui-ci offre moins de résistance à la déformation que les moyens élastiques. Sans quoi, le diamètre du tasseau demeure insuffisant pour immobiliser la pièce. Grâce à l'utilisation d'un tasseau déformable élastiquement, la présente invention permet en outre de fournir une boîte pouvant recevoir des pièces en forme de plaque qui diffèrent quant au diamètre de leur ouverture.According to the present invention, the elastic means must return the flange towards the cover with sufficient force to hold the cleat wedged in the opening of the plate-shaped part. That is to say that, to maintain the cleat wedged in the opening of the plate, it is necessary that it offers less resistance to deformation than the elastic means. Otherwise, the diameter of the cleat remains insufficient to immobilize the room. Through the use of an elastically deformable cleat, the present invention further provides a box capable of receiving plate-shaped parts that differ in the diameter of their opening.
Selon une variante avantageuse de la présente invention, le tasseau comporte un élément tubulaire fendu longitudinalement, la parois fendue de l'élément tubulaire constituant au moins deux bras élastiques. De plus, lors de la fermeture de la boîte, la saillie formée sous le couvercle est prévue pour s'introduire dans l'élément tubulaire fendu, à la manière d'un coin, pour écarter lesdits bras élastiques.According to an advantageous variant of the present invention, the cleat comprises a longitudinally split tubular element, the slotted wall of the tubular element constituting at least two elastic arms. In addition, when closing the box, the projection formed under the cover is intended to be introduced into the split tubular element in the manner of a wedge, to separate said elastic arms.
Selon encore une autre variante avantageuse de la présente invention, la flasque est ajourée. Cette caractéristique présente notamment l'avantage de permettre de conditionner des cadrans déjà munis de pied de cadran. D'autre part, si la caractéristique d'une flasque ajourée est combinée avec celle d'un fond transparent ou translucide, cette combinaison présente l'avantage de permettre l'indentification d'une référence ou d'un code barre éventuellement porté par la face inférieure de la plaque ou du cadran. Ainsi, il n'est pas nécessaire d'ouvrir la boîte pour prendre connaissance de son contenu.According to yet another advantageous variant of the present invention, the flange is perforated. This feature has the particular advantage of allowing to condition dials already equipped with dial feet. On the other hand, if the characteristic of a perforated flange is combined with that of a transparent or translucent background, this combination has the advantage of allowing the identification of a reference or a bar code possibly carried by the underside of the plate or dial. Thus, it is not necessary to open the box to learn about its contents.
Selon encore une autre variante avantageuse, les moyens élastiques pour rappeler la flasque en direction du couvercle sont des ressorts hélicoïdaux. Selon encore une autre variante avantageuse, la boîte porte un signe distinctif indiquant le diamètre du tasseau qu'elle contient.According to yet another advantageous variant, the elastic means for biasing the flange towards the cover are helical springs. According to yet another advantageous variant, the box bears a distinctive sign indicating the diameter of the cleat it contains.
Un mode de réalisation particulier de l'invention va maintenant être décrit en détail à titre d'exemple en se référant aux dessins annexés dans lesquels : la figure 1 est une vue en perspective d'une boîte protectrice pour le transport et le stockage d'un cadran de montre correspondant à un mode particulier de réalisation de la présente invention ; la figure 2 est une vue en coupe de la boîte protectrice de la figure 1 ; la figure 3 est une vue en coupe agrandie montrant le cône et les bras du tasseau constituant un exemple de moyens de serrage selon la présente invention ; la figure 4 est une vue en éclaté permettant de comprendre le mode d'assemblage des différents constituants de la boîte protectrice ; la figure 5 est une vue en coupe agrandie montrant le petit épaulement intérieur que présente la partie supérieure du rebord cylindrique. En se référant aux figures 1 et 2, on peut voir que la boîte 1 comporte tout d'abord une ensceinte définie par l'assemblage d'un fond 2 avec un couvercle transparent 3. Ces deux pièces présentent des rebords cylindriques (respectivement référencés 4 et 5) qui sont prévus pour s'emboîter. A l'intérieur de l'ensceinte est logée une flasque mobile 6 qui est prévue pour coulisser axialement à l'intérieur du rebord cylindrique 4. Cette flasque 6 porte un tasseau 7 qui est monté fixe au centre de sa face supérieure. Comme le montre plus en détail la figure 3, le tasseau 7 est constitué par un élément tubulaire qui est fendu en quatre longitudinalement, de manière à former quatre bras. Cet élément tubulaire est réalisé dans un matériau élastique comme du téflon par exemple. Comme on le verra plus en détail plus loin, le tasseau 7 est prévu pour coopérer avec une saillie en forme de cône 8 formée au centre de la face inférieure du couvercle 3. Finalement, la flasque 6 est suspendue sur quatre ressorts hélicoïdaux 9a, 9b, 9c et 9d qui sont comprimés entre la flasque 6 et le fond 2 (seul deux ressorts référencés 9a et 9c sont visibles dans la vue en coupe de la figure 2). Les quatre ressorts constituent des moyens élastiques prévus pour rappeler la flasque 6 en direction du couvercle 3.A particular embodiment of the invention will now be described in detail by way of example with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a protective box for the transport and storage of a watch face corresponding to a particular embodiment of the present invention; Figure 2 is a sectional view of the protective box of Figure 1; Figure 3 is an enlarged sectional view showing the cone and arms of the cleat constituting an example of clamping means according to the present invention; Figure 4 is an exploded view to understand the method of assembly of the various components of the protective box; Figure 5 is an enlarged sectional view showing the small inner shoulder that has the upper portion of the cylindrical rim. Referring to FIGS. 1 and 2, it can be seen that the box 1 comprises firstly a box defined by the assembly of a bottom 2 with a transparent cover 3. These two parts have cylindrical flanges (respectively referenced 4). and 5) which are intended to fit together. Inside the enclosure is housed a movable flange 6 which is provided to slide axially inside the cylindrical flange 4. This flange 6 carries a batten 7 which is fixedly mounted in the center of its upper face. As shown in more detail in Figure 3, the cleat 7 is constituted by a tubular element which is split in four longitudinally, so as to form four arms. This tubular element is made of an elastic material such as Teflon for example. As will be seen in more detail below, the cleat 7 is provided to cooperate with a cone-shaped projection 8 formed in the center of the lower face of the lid 3. Finally, the flange 6 is suspended on four coil springs 9a, 9b , 9c and 9d which are compressed between the flange 6 and the bottom 2 (only two springs referenced 9a and 9c are visible in the sectional view of Figure 2). The four springs constitute elastic means provided to return the flange 6 towards the cover 3.
Le fonctionnement de la boîte va maintenant être décrit en référance aux figures 2 et 3. La boîte est tout d'abord posée à plat, et le couvercle 3 est enlevé. Un cadran 1 1 peut ensuite être introduit dans la boîte est positionné à plat sur la flasqueThe operation of the box will now be described with reference to Figures 2 and 3. The box is first laid flat, and the lid 3 is removed. A dial 1 1 can then be introduced into the box is positioned flat on the flange
6, avec le tasseau s'étendant à travers le trou de centre du cadran. La boîte peut ensuite être refermée.6, with the cleat extending through the center hole of the dial. The box can then be closed again.
Dès que l'abaissement du couvercle provoque la rencontre du cône 8 et du tasseau 7 (qui forment ensemble le dispositif de serrage), la pointe du cône va - A -As soon as the lowering of the lid causes the cone 8 and the cleat 7 (which together form the clamping device) to meet, the tip of the cone - AT -
s'introduire à la manière d'un coin entre les quatres bras du tasseau. Le cône va ainsi pousser les quatre bras radialement de manière à ce qu'il s'écartent suffisament pour venir buter contre le bord intérieur du trou de centre du cadran 1 1 , immobilisant ainsi le cadran. Dès que la pince formée par les quatre bras du tasseau presse contre les flancs du trou de centre, le tasseau 7 ne peut plus se déformer. C'est donc la flasque mobile 6 qui s'abaisse sous la pression du couvercle 3 en comprimant les ressorts 9a, 9b, 9c et 9d, jusqu'à ce que la boîte soit complètement fermée. A ce moment là, les rebords cylindriques 4 et 5 sont complètement emboîtés. On comprendra que selon le principe de fonctionnement qui vient d'être décrit, l'élasticité du tasseau 7 et celle des moyens élastiques 9a, 9b, 9c et 9d assurant la suspension de la flasque 6 sont, en quelque sorte, en concurrence pour accompagner l'abbaissement du couvercle 3 et du cône 8. Il est donc important que les moyens élastiques soient suffisament résistants à la déformation pour permettre le calage des bras du tasseau 7 dans le trou de centre du cadran 1 1. Cela revient à dire qu'il est nécessaire que le tasseau soit plus souple que les moyens élastiques. Sans quoi, le diamètre du tasseau ne peut pas augmenter suffisament pour immobiliser le cadran.to introduce itself as a wedge between the four arms of the cleat. The cone will push the four arms radially so that it deviates sufficiently to abut against the inner edge of the center hole of the dial 1 1, thus immobilizing the dial. As soon as the clamp formed by the four arms of the cleat press against the sides of the center hole, the cleat 7 can no longer be deformed. It is therefore the mobile flange 6 which lowers under the pressure of the lid 3 by compressing the springs 9a, 9b, 9c and 9d, until the box is completely closed. At this moment, the cylindrical flanges 4 and 5 are completely nested. It will be understood that according to the operating principle which has just been described, the elasticity of the cleat 7 and that of the elastic means 9a, 9b, 9c and 9d ensuring the suspension of the flange 6 are, in a way, in competition with each other. the lowering of the cover 3 and the cone 8. It is therefore important that the elastic means are sufficiently resistant to deformation to allow the wedging of the arms of the cleat 7 in the center hole of the dial 1 1. This amounts to saying that it is necessary that the cleat is more flexible than the elastic means. Otherwise, the diameter of the cleat can not increase enough to immobilize the dial.
Selon le mode de réalisation de l'invention qui fait l'objet du présent exemple, une même gamme de boîtes et prévue pour accommoder tous les modèles de cadran d'un fabriquant. De plus, dans le présent exemple, les différentes boîtes de la gamme se distinguent uniquement par les dimensions de leur tasseau. Comme les tasseaux sont interchangeables, on comprendra qu'il est possible de conditionner l'ensemble des cadrans d'un fabriquant avec le même modèle de boîte. Comme on va le voir plus en détail, selon le présent exemple, les tasseaux eux-mêmes peuvent être indentiques en tout point, exception faite du diamètre (extérieur et intérieur) de la pince formée par les bras du tasseau.According to the embodiment of the invention which is the subject of this example, the same range of boxes and provided to accommodate all dial models of a manufacturer. In addition, in the present example, the different boxes of the range are distinguished only by the dimensions of their cleat. As the cleats are interchangeable, it will be understood that it is possible to package all the dials of a manufacturer with the same model box. As will be seen in more detail, according to the present example, the cleats themselves can be identical in every way, except for the diameter (outside and inside) of the clamp formed by the arms of the cleat.
Supposons à titre d'exemple que les différents modèles de cadran que l'on désire conditionner à l'aide de boîtes selon la présente invention ont des épaisseurs au centre comprises entre 0.25mm et 1 mm. Suposons de plus que les diamètres des trous de cadran de ces cadrans sont compris entre 1.1 mm et 2.7mm. A titre d'exemple, on pourra choisir d'avoir quatre modèles de tasseau avec des diamètres de pince différents. Tous ces tasseaux pourront avoir la même hauteur de 1.1 mm de manière à pouvoir recevoir tous les cadrans : - le premier modèle de tasseau pourra avoir une pince avec un diamètre extérieur de 1.05mm. Ce modèle pourra convenir pour des diamètres de trou de cadran compris entre environ 1.1 mm et 1.65mm. - le deuxième modèle de tasseau pourra avoir une pince avec un diamètre de 1.45mm. Ce modèle pourra convenir pour des diamètres de trou de cadran compris entre environ 1.65mm et 1.9mm.Suppose for example that the different dial models that are desired to be packaged using boxes according to the present invention have thicknesses in the center of between 0.25 mm and 1 mm. Suposons more than the diameters of the dial holes of these dials are between 1.1 mm and 2.7mm. For example, we can choose to have four models of cleat with different clamp diameters. All these cleats will be able to have the same height of 1.1 mm so as to be able to receive all the dials: - the first model of cleat can have a clamp with an outside diameter of 1.05mm. This model may be suitable for dial hole diameters of between 1.1 mm and 1.65 mm. - The second model of cleat can have a clamp with a diameter of 1.45mm. This model may be suitable for dial hole diameters of between 1.65mm and 1.9mm.
- le troisième modèle de tasseau pourra avoir une pince avec un diamètre de 1.65mm. Ce modèle pourra convenir pour des diamètres de trou de cadran compris entre environ 1.7mm et 2.3mm.- The third model of cleat can have a clamp with a diameter of 1.65mm. This model may be suitable for dial hole diameters between about 1.7mm and 2.3mm.
- le quatrième modèle de tasseau pourra avoir une pince avec un diamètre de 2.35mm. Ce modèle pourra convenir pour des diamètres de trou de cadran compris entre environ 2.4mm et 2.7mm. Si comme dans le présent exemple, les tasseaux sont réalisés en téflon, l'épaisseur de la paroi de l'élément tubulaire du tasseau pourra être, par exemple, de 0.3mm pour le modèle de tasseau le plus petit. Pour les trois modèles plus grand, l'épaisseur de la paroi pourra être par exemple de 0.5mm.- The fourth model of cleat can have a clamp with a diameter of 2.35mm. This model may be suitable for dial hole diameters between approximately 2.4mm and 2.7mm. If, as in the present example, the cleats are made of Teflon, the thickness of the wall of the tubular element of the cleat may be, for example, 0.3mm for the smallest cleat model. For the three larger models, the thickness of the wall may for example be 0.5mm.
D'autre part, Le cône 8 est de préférence dimensionné de manière à garder un certain écartement entre le dessus d'un cadran et le dessous du couvercle, quel que soit le diamètre du trou de centre du cadran. Cette condition est respectée, par exemple, si le cône présente un angle au sommet de 90° et que sa base circulaire possède un diamètre de 3mm.On the other hand, the cone 8 is preferably sized to keep a certain distance between the top of a dial and the underside of the lid, regardless of the diameter of the center hole of the dial. This condition is met, for example, if the cone has an apex angle of 90 ° and its circular base has a diameter of 3mm.
On voit de plus, sur la figure 5, que le rebord cylindirque 4, à l'intérieur duquel se déplace la flasque 6, présente un petit épaulement intérieur 16 qui est prévu pour limiter la course de la flasque 6 vers le haut. La présence de l'épaulement 16 permet d'éviter que la flasque 6 ne se désengage du rebord cylindrique 4 lorsqu la boîte est ouverte. D'autre part, lorsque la boîte est fermée, l'épaulement 16 garantit que le dessus du cadran 1 1 ne puisse pas venir en contact avec le dessous du couvercle 3. L'assemblage de la boîte va maintenant être décrit en s'appuyant sur les figures 4 et 5. La première opération de montage consiste en la mise en place des ressorts 9a, 9b, 9c et 9d dans les logements 17a, 17b, 17c et 17d aménagés à cet effet dans l'épaisseur du fond 2. Les ressorts peuvent par exemple être simplement posés dans les logements sans aucun moyen de fixation. La seconde opération consiste en le montage de la flasque 6 sur le fond. Le diamètre extérieur de la flasque et le diamètre intérieur du rebord 4 sont ajustés de manière à ce que la flasque puisse coulisser tout en étant maintenue latéralement. Toutefois, comme on l'a déjà dit, le rebord 4 présente, dans sa partie supérieure, un petit épaulement intérieur 16 prévu pour limiter la course de la flasque 6 et l'empêcher de se désengager du rebord cylindrique 4. Le diamètre intérieur de l'épaulement 16 est légèrement inférieur au diamètre extérieur de la flasque 6. Dans ces conditions, lors de l'assemblage, pour introduire la flasque dans le fond 2, il est nécessaire de forcer le passage. Cette opération est rendue possible par l'élasticité du matériau dont sont faits le rebord 4 et le fond 2. Ce matériau peut être par exemple du polystirène.It is further seen in FIG. 5 that the cylindrical flange 4, within which the flange 6 moves, has a small inner shoulder 16 which is provided to limit the travel of the flange 6 upwards. The presence of the shoulder 16 prevents the flange 6 from disengaging the cylindrical flange 4 when the box is open. On the other hand, when the box is closed, the shoulder 16 ensures that the top of the dial 1 1 can not come into contact with the underside of the lid 3. The assembly of the box will now be described by leaning in FIGS. 4 and 5. The first assembly operation consists in placing the springs 9a, 9b, 9c and 9d in the housings 17a, 17b, 17c and 17d arranged for this purpose in the thickness of the bottom 2. The For example, the springs can simply be placed in the housings without any means of attachment. The second operation consists in mounting the flange 6 on the bottom. The outside diameter of the flange and the inside diameter of the flange 4 are adjusted so that the flange can slide while being held laterally. However, as has already been said, the rim 4 has, in its upper part, a small internal shoulder 16 designed to limit the stroke of the flange 6 and prevent it from disengaging from the cylindrical rim 4. The inner diameter of the shoulder 16 is slightly smaller than the outer diameter of the flange 6. Under these conditions, during assembly, to introduce the flange into the bottom 2, it is necessary to force the passage. This operation is made possible by the elasticity of the material of which the flange 4 and the bottom 2 are made. This material may for example be polystirene.
Quatre logements 10a, 10b, 10c et 10d, prévus chacun pour recevoir l'extrémité supérieure d'un des ressorts hélicoïdaux 9a, 9b, 9c et 9d, sont encore aménagés dans la partie inférieure de la flasque 6. Lors du montage, avant de chasser la flasque 6 dans le fond 2, il est nécessaire de prépositionner la flasque 6 au dessus du fond 2 avec les quatre logements à la verticale des ressorts. A cet effet, on voit sur la figure 4 que le rebord 4 présente deux chanfreins 13 destinés à faciliter l'orientation correcte de la flasque 6 par rapport au fond 2. Lors de l'étape suivante de chassage de la flasque dans le fond, la présence des chanfreins 13 facilite également l'introduction de la flasque. Le chassage lui-même se fait de préférence avec un outil de chassage présentant une grande surface d'appui, de manière à ce que la flasque 6 descende parralèlellement au fond 2. Une fois la flasque 6 en place, l'étape suivante est le montage du tasseau 7 sur la flasque. Comme on l'a vu, dans le présent exemple, plusieurs modèles de tasseaux, avec des éléments tubulaires de diamètres différents, sont requis pour accommoder toute la gamme des cadrans existants. Dans le présent exemple, tous les modèles de tasseaux présentent une embase 14 de même diamètre. Cette caractéristique assure l'interchangeabilité des tasseaux.Four housings 10a, 10b, 10c and 10d, each intended to receive the upper end of one of the helical springs 9a, 9b, 9c and 9d, are further arranged in the lower part of the flange 6. During assembly, before to drive the flange 6 in the bottom 2, it is necessary to preposition the flange 6 above the bottom 2 with the four housings vertical springs. For this purpose, we see in Figure 4 that the flange 4 has two chamfers 13 to facilitate the correct orientation of the flange 6 relative to the bottom 2. During the next step of driving the flange in the bottom, the presence of the chamfers 13 also facilitates the introduction of the flange. The driving itself is preferably with a driving tool having a large bearing surface, so that the flange 6 downwards parallel to the bottom 2. Once the flange 6 in place, the next step is the mounting the cleat 7 on the flange. As we have seen, in this example, several models of cleats, with tubular elements of different diameters, are required to accommodate the entire range of existing dials. In the present example, all models of cleats have a base 14 of the same diameter. This characteristic ensures the interchangeability of the cleats.
La flasque 6 présente au centre de sa face supérieure un logement constitué par un chambrage cylindrique 15 prévu pour recevoir le tasseau 7. Le diamètre intérieur du chambrage 15 correspond au diamètre extérieur de l'embase 14, de sorte que le tasseau puisse être chassé jusqu'au fond du chambrage et y être maintenu._L'introduction du tasseau dans le chambrage est de préférence effectuée avec un outil conçu de manière à éviter d'abîmer la pince du tasseau. Cette outil peut par exemple avoir la forme d'un tube entourant l'élément cylindrique du tasseau et venant en appui contre l'embase 14.The flange 6 has in the center of its upper face a housing constituted by a cylindrical recess 15 provided to receive the cleat 7. The inner diameter of the recess 15 corresponds to the outer diameter of the base 14, so that the cleat can be driven up to At the bottom of the recess and to be maintained therein. The insertion of the batten into the recess is preferably carried out with a tool designed so as to avoid damaging the clamp of the cleat. This tool may for example have the shape of a tube surrounding the cylindrical element of the cleat and bearing against the base 14.
On voit sur la figure 7 que le chambrage cylindrique 15 se prolonge du côté inférieur de la flasque par un trou circulaire 16 traversant. Le fond 2 de la boîte est également percé d'un trou 18 traversant disposé dans le prolongement de l'axe du chambrage 15. Grâce à la présence de ces deux trous alignés il est possible de retirer le tasseau 7 de la boîte sans qu'il soit nécessaire, au préalable, d'extraire la flasque 6 du fond 2. En effet, en insérant une goupille par le fond dans les trous 18 et 16, il est possible d'éjecter le tasseau 7 de son logement 15. Cette possibilité est utile par exemple lorsqu'on veut remplacer le tasseau en place par un tasseau de diamètre différent. On comprendra que diverses modifications et/ou améliorations évidentes pour un homme du métier peuvent être apportées au mode de réalisation décrit dans la description sans sortir du cadre de la présente invention définie par les revendications annexées. On pourra notamment prévoir dans d'autres modes de réalisation que flasque et tasseau viennent réalisés en une seule pièce, de façon à réduire les coûts de production. Dans ces conditions, on pourra par exemple adapter une boîte selon l'invention à une autre dimension de cadran simplement en changeant de flasque. On pourra aussi prévoir dans d'autres variantes de réalisation de réaliser le tasseau non pas sur la flasque mais sur le couvercle, dans ce cas le cône coopérant avec le tasseau sera arrangé sur la flasque.It can be seen in FIG. 7 that the cylindrical recess 15 is extended on the lower side of the flange by a circular through hole 16. The bottom 2 of the box is also pierced with a through-hole 18 disposed in the extension of the axis of the recess 15. Thanks to the presence of these two aligned holes it is possible to remove the cleat 7 from the box without which it is necessary, beforehand, to extract the flange 6 from the bottom 2. In fact, by inserting a pin by the bottom in the holes 18 and 16, it is possible to eject the batten 7 from its housing 15. This possibility is useful for example when you want to replace the cleat in place by a cleat of different diameter. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment described in the description without departing from the scope of the present invention defined by the appended claims. It may be provided in other embodiments that the flange and flange are made in one piece, so as to reduce production costs. Under these conditions, for example, a box according to the invention can be adapted to another dial dimension simply by changing the flange. It may also be provided in other embodiments to make the cleat not on the flange but on the cover, in this case the cone cooperating with the cleat will be arranged on the flange.
On pourra notamment prévoir d'utiliser la boîte selon l'invention pour conditionner d'autres pièces en forme de plaque que des cadrans de montre. On pense notamment à des supports d'informations sous forme de disques. D'autre part, dans l'exemple de la description détaillée, le couvercle est transparent. Cette caractéristique présente l'avantage de permettre de lire des indications portées sur la face supérieure du cadran sans ouvrir la boîte. De plus, dans l'exemple, la flasque est ajourée. Cette caractéristique présente notamment l'avantage de permettre de conditionner des cadrans déjà munis de pied de cadran. D'autre part, si la caractéristique d'une flasque ajourée est combinée avec celle d'un fond transparent ou translucide, cette combinaison présente l'avantage de permettre l'indentification d'une référence ou d'un code barre éventuellement porté par la face inférieure du cadran.In particular, it will be possible to use the box according to the invention for packaging other plate-shaped parts than watch dials. One thinks in particular of information carriers in the form of disks. On the other hand, in the example of the detailed description, the cover is transparent. This feature has the advantage of allowing to read indications on the upper face of the dial without opening the box. In addition, in the example, the flange is perforated. This feature has the particular advantage of allowing to condition dials already equipped with dial feet. On the other hand, if the characteristic of a perforated flange is combined with that of a transparent or translucent background, this combination has the advantage of allowing the identification of a reference or a bar code possibly carried by the lower face of the dial.
Dans l'exemple de la description détaillée, les moyens élastiques pour rappeler la flasque en direction du couvercle sont des ressorts hélicoïdaux. On comprendra, toutefois, que tout autre forme de moyens de rappel connue de l'homme du métier est susceptible d'être utilisée dans la présente invention.In the example of the detailed description, the resilient means for biasing the flange towards the cover are helical springs. It will be understood, however, that any other form of return means known to those skilled in the art may be used in the present invention.
Enfin, pour faciliter la gestion des boîtes, il est possible de prévoir qu'elles portent un signe distinctif indiquant le diamètre du tasseau qu'elles contiennent. Finally, to facilitate the management of the boxes, it is possible to provide that they carry a distinctive sign indicating the diameter of the cleat they contain.
