La présente invention concerne un dispositif de fixation d'un fond sur une carrure d'une montre. Plus précisément, l'invention concerne un tel dispositif qui permet l'alignement d'une tel fond par rapport à l'axe 12H-6H de la montre.The present invention relates to a device for fixing a bottom on a middle part of a watch. More specifically, the invention relates to such a device that allows the alignment of such a background with respect to the axis 12H-6H of the watch.
Il arrive fréquemment que, lors du vissage d'un fond de boîte de montre sur la carrure de cette dernière, on s'aperçoive que, lorsque le fond est complètement vissé, les inscriptions ou motifs décoratifs qui peuvent avoir été par exemple frappés par étampage ou gravés sur la face du fond située du côté du poignet du porteur de la montre, ne sont pas convenablement alignés par rapport à l'axe vertical 12 heures- 6 heures de ladite montre ce qui, bien entendu, nuit à l'aspect esthétique de cette montre.It often happens that, when screwing a watchcase back on the middle part of the latter, it becomes apparent that, when the bottom is completely screwed, the inscriptions or decorative motifs that may have been for example struck by stamping or engraved on the face of the bottom located on the wrist side of the wearer of the watch, are not properly aligned with respect to the vertical axis 12 hours to 6 hours of said watch which, of course, detracts from the aesthetic appearance of this watch.
Ce défaut d'aspect, s'il peut être toléré pour des montres bon marché, constitue un inconvénient très gênant pour des montres plus onéreuses.This lack of appearance, if it can be tolerated for cheap watches, is a disadvantage very troublesome for more expensive watches.
Pour remédier à cet inconvénient, la seule solution connue par le passé consistait à apparier un fond avec une boîte de montre déterminée lors de l'usinage, de façon à être assuré qu'une fois complètement vissé, le fond fût parfaitement aligné avec l'axe 12h-6h de la montre. Cette solution n'était toutefois que peu satisfaisante car on s'exposait à des problèmes si jamais le fond d'origine de la montre était perdu ou abîmé et qu'il était nécessaire de le remplacer par un autre fond dont on n'était pas sûr qu'une fois vissé sur la carrure, il s'alignât toujours convenablement avec l'axe vertical 12h-6h.To remedy this drawback, the only solution known in the past was to match a bottom with a watch case determined during the machining, so as to be sure that once completely screwed, the bottom was perfectly aligned with the axis 12h-6h of the watch. This solution, however, was unsatisfactory because of the risk of problems if the original background of the watch was lost or damaged and it was necessary to replace it with another background of which it was not necessary. sure that once screwed on the middle part, it always aligned correctly with the vertical axis 12h-6h.
Une première solution à ce problème a été proposée par la Demanderesse de la présente demande dans le document de brevet EP-A-1278108 qui décrit un dispositif de fixation d'un fond sur la carrure d'une boîte de montre, le fond présentant un filetage périphérique extérieur. Ce dispositif comprend un ensemble intermédiaire comportant un élément élastique de blocage et un élément métallique concentrique à l'élément élastique de blocage, cet ensemble intermédiaire étant engagé à force dans la partie inférieure de la carrure de la montre et le fond étant fixé par vissage sur l'élément métallique de sorte que, lorsque le fond est complètement vissé sur l'élément métallique, cet élément métallique peut être pivoté en glissant sur l'élément élastique de blocage jusqu'à un point de butée à partir duquel l'élément élastique de blocage peut pivoter à son tour en glissant sur la carrure de la montre, ceci permettant de régler l'alignement du fond par rapport à l'axe vertical 12h-6h de la montre. La solution brièvement décrite ci-dessus a pour mérite d'apporter une première réponse au problème de l'alignement du fond d'une boîte de montre par rapport à l'axe 12h-6h de cette dernière. En particulier, elle permet de garantir que le fond sera toujours convenablement aligné indépendamment des caractéristiques d'usinage dudit fond et de la carrure. Toutefois, cette solution met en jeu un nombre important de pièces et nécessite le recours à une goupille chassée dans la carrure et formant butée dont on peut craindre qu'elle ne soit pas suffisamment résistante. La présente invention a pour but de remédier aux inconvénients susmentionnées ainsi qu'à d'autre encore en procurant un dispositif de fixation d'un fond sur une carrure de montre dont le nombre de pièces est limité et dont le fonctionnement est fiable.A first solution to this problem has been proposed by the Applicant of the present application in the patent document EP-A-1278108 which describes a device for fixing a bottom to the middle part of a watch case, the bottom presenting a outer peripheral thread. This device comprises an intermediate assembly comprising a resilient locking element and a metal element concentric with the elastic locking element, this intermediate assembly being forcibly engaged in the lower part of the middle part of the watch and the bottom being fixed by screwing on the metallic element so that, when the bottom is completely screwed onto the metal element, this metal element can be pivoted by sliding on the elastic locking element to a stop point from which the elastic element of blocking can rotate in turn by sliding on the middle of the watch, this to adjust the alignment of the bottom with respect to the vertical axis 12h-6h of the watch. The solution briefly described above has the merit of providing an initial answer to the problem of the alignment of the bottom of a watch case with respect to the axis 12h-6h of the latter. In particular, it ensures that the bottom will always be properly aligned regardless of the machining characteristics of said bottom and middle part. However, this solution involves a large number of parts and requires the use of a pin driven into the middle and forming a stop that can be feared that it is not sufficiently strong. The present invention aims to overcome the aforementioned drawbacks as well as still others by providing a device for fixing a bottom on a watchband whose number of parts is limited and whose operation is reliable.
A cet effet, la présente invention concerne un dispositif de fixation d'un fond sur une carrure d'une boîte de montre, caractérisé en ce qu'il comprend un élément intermédiaire auquel le fond est lié, cet élément intermédiaire étant vissé sur la carrure de la montre, des moyens étant prévus pour permettre au fond d'entraîner l'élément intermédiaire en rotation jusqu'à ce que ce dernier arrive en position de blocage sur la carrure, le fond étant en outre capable d'être pivoté par rapport à l'élément intermédiaire sans que celui-ci ne se dévisse pour son alignement avec l'axe 12h-6h de la montre. Grâce à ces caractéristiques, la présente invention procure un dispositif de fixation d'un fond sur une carrure d'une boîte de montre dont le faible nombre de pièces rend son montage aisé et son fonctionnement extrêmement fiable. Après vissage à fond de l'élément intermédiaire sur la carrure de la montre, on peut régler l'alignement du fond par rapport à l'axe 12h-6h de ladite montre sans que ledit élément intermédiaire ne se dévisse, ce qui rend le dispositif de fixation selon l'invention totalement imperdable. En outre, le couple à exercer pour pivoter le fond de la montre et régler son alignement est bien supérieur au couple que l'on pourrait exercer à la main, de sorte que l'alignement dudit fond ne peut être modifié de façon involontaire. On notera que le couple de frottement peut être réglé à volonté selon le type de construction envisagé.For this purpose, the present invention relates to a device for fixing a bottom to a middle part of a watch case, characterized in that it comprises an intermediate element to which the bottom is connected, this intermediate element being screwed on the middle part of the watch, means being provided to allow the bottom to drive the intermediate element in rotation until the latter arrives in the locking position on the middle part, the bottom being furthermore capable of being pivoted relative to the intermediate element without it unscrews for alignment with the axis 12h-6h of the watch. Thanks to these features, the present invention provides a device for fixing a bottom on a middle part of a watch case whose small number of parts makes its easy assembly and extremely reliable operation. After fully screwing the intermediate element on the middle part of the watch, it is possible to adjust the alignment of the base with respect to the axis 12h-6h of said watch without said intermediate element being unscrewed, which makes the device fixing according to the invention completely captive. In addition, the torque to be exerted to pivot the bottom of the watch and adjust its alignment is much greater than the torque that could be exercised by hand, so that the alignment of said bottom can not be modified unintentionally. It will be noted that the friction torque can be adjusted at will according to the type of construction envisaged.
Selon une autre caractéristique de l'invention, le fond comporte une rainure oblongue en arc de cercle dans laquelle est logée une pièce d'entraînement qui est libre de s'y déplacer et qui coopère avec une butée prévue sur l'élément intermédiaire pour entraîner ce dernier en rotation jusqu'à ce qu'il arrive en position de blocage sur la carrure. La pièce d'entraînement et la butée prévue sur l'élément intermédiaire sont extrêmement résistantes, de sorte que tout risque de voir cette pièce ou cette butée se détériorer est évité.According to another characteristic of the invention, the bottom comprises an oblong arcuate groove in which is housed a drive member which is free to move and cooperates with a stop provided on the intermediate element to drive the latter in rotation until it arrives in blocking position on the middle part. The drive part and the stop provided on the intermediate element are extremely resistant, so that any risk of this part or this abutment deteriorating is avoided.

La figure 1 est une vue en perspective et en éclaté des différents éléments constituant la présente invention. En examinant la figure 1 de bas en haut, on voit tout d'abord un fond 1 de forme générale circulaire dans lequel est ménagé un évidemment oblong en arc de cercle 2. A proprement parler, le dispositif de fixation du fond 1 selon l'invention, désigné dans son ensemble par la référence générale 4, comprend une pièce d'entraînement 6 telle qu'une bille, une clavette ou toute autre pièce de forme, un élément de liaison 8 tel qu'un ressort à pans et un élément intermédiaire 10. Comme on le verra dans la suite de la description, ce dispositif de fixation 4 sert au montage du fond 1 sur une carrure 12 d'une boîte de montre. L'ensemble représenté à la figure 1 comprend encore un joint d'étanchéité 14 qui permet notamment de garantir l'étanchéité de la boîte de montre.Figure 1 is a perspective and exploded view of the various elements constituting the present invention. By examining FIG. 1 from bottom to top, a bottom 1 of generally circular shape is seen first, in which an elongated oblong recess 2 is provided. Strictly speaking, the device for fixing the bottom 1 according to FIG. The invention, generally designated by the general reference 4, comprises a driving part 6 such as a ball, a key or any other piece of shape, a connecting element 8 such as a slotted spring and an intermediate element. 10. As will be seen in the following description, this fixing device 4 is used for mounting the bottom 1 on a middle part 12 of a watch case. The assembly shown in Figure 1 further comprises a seal 14 which allows in particular to ensure the sealing of the watch case.
Le fond 1 de la boîte de montre va être examiné plus en détail en liaison avec les figures 2 à 4. Comme il ressort de ces figures, sur le fond 1 de forme générale circulaire se dresse une collerette annulaire 16 à distance du pourtour extérieur dudit fond 1. Cette collerette annulaire 16 délimite ainsi une surface périphérique extérieure 18 dans laquelle est ménagée une rainure circulaire 20 qui s'étend entre ladite collerette 16 et un rebord 22. Dans la surface inférieure du fond 1 tournée du côté du poignet du porteur de la montre sont ménagées plusieurs encoches 24 (six dans l'exemple représenté au dessin) qui servent à l'introduction des tenons d'une clé de serrage (non représentée) qui permettra de visser complètement l'élément intermédiaire 10 sur la carrure 12 puis d'orienter convenablement le fond 1 par rapport à l'axe 12h-6h de la montre. On notera que cet exemple est donné à titre purement illustratif seulement et que la présente invention peut s'appliquer à d'autres types de fonds vissés tels que des fonds à pans ou sans encoches connus par l'homme du métier. Par ailleurs, dans le pourtour extérieur de la collerette 16 est ménagée une saignée circulaire 26 qui est destinée à former avec une saignée correspondante 28 pratiquée dans l'élément intermédiaire 10 une gorge annulaire 30 dans laquelle sera logé l'élément de liaison 8 comme décrit en détail ci-après. Enfin, un évidemment oblong 2 en arc de cercle est pratiqué de manière concentrique dans la rainure circulaire 20. Cet évidemment oblong 2 dans lequel la pièce d'entraînement 6 est libre de se déplacer forme, dans l'exemple représenté au dessin, un angle α de 40°. Il va de soi que cette valeur est donnée à titre purement illustratif seulement et que l'évidemment oblong 2 peut former un angle aussi petit que 10° ou aussi grand que 350°, la seule condition pesant sur les dimensions de cet évidemment 2 étant qu'il soit au moins aussi long que la somme des longueurs (ou diamètre) de la pièce d'entraînement 6 et d'une butée 34 dont est muni l'élément intermédiaire 10. On notera que l'évidemment 2 peut être pratiqué en un endroit quelconque de la rainure 20, ce qui signifie qu'aucune indexation n'est à prévoir entre le fond 1 , l'élément intermédiaire 10 et la carrure 12.The bottom 1 of the watch case will be examined in more detail in connection with FIGS. 2 to 4. As can be seen from these figures, on the bottom 1 of generally circular shape there is an annular flange 16 remote from the outer periphery of said 1. This annular flange 16 defines an outer peripheral surface 18 in which is formed a circular groove 20 which extends between said flange 16 and a flange 22. In the lower surface of the bottom 1 rotated on the wrist side of the wearer. the watch are provided several notches 24 (six in the example shown in the drawing) which serve to introduce the tenons of a wrench (not shown) which will allow to fully screw the intermediate element 10 on the middle part 12 and then to properly orient the bottom 1 with respect to the axis 12h-6h of the watch. Note that this example is given for illustrative purposes only and that the present invention can be applied to other types of screwed bottoms such as slatted bottoms or without notches known to those skilled in the art. Furthermore, in the outer periphery of the flange 16 is formed a circular groove 26 which is intended to form with a corresponding groove 28 formed in the intermediate element 10 an annular groove 30 in which will be housed the connecting element 8 as described in detail below. Finally, a recess oblong 2 in an arc is made concentrically in the circular groove 20. This oblong oblong 2 in which the drive part 6 is free to move form, in the example shown in the drawing, an angle α 40 °. It goes without saying that this value is given for purely illustrative purposes only and that oblong oblong 2 can form an angle as small as 10 ° or as large as 350 °, the only condition weighing on the dimensions of this obviously 2 being that it is at least as long as the sum of the lengths (or diameter) of the driving part 6 and a stop 34 which is provided with the intermediate element 10. It will be noted that the recess 2 can be practiced in one anywhere in the groove 20, which means that no indexing is to be expected between the bottom 1, the intermediate element 10 and the middle part 12.
On examine maintenant plus en détail l'élément intermédiaire 10 et la façon dont il permet le montage du fond 1 sur la carrure 12 de la boîte de montre en liaison avec les figures 5 à 8. Comme il ressort de ces figures, l'élément intermédiaire 10 est une pièce de forme circulaire sur le pourtour extérieur de laquelle est usiné un filetage 36 destiné à coopérer avec un filetage correspondant 38 prévu sur le pourtour intérieur de la carrure 12. Dans le pourtour intérieur de la pièce intermédiaire 10 est pratiquée la saignée 28 qui forme avec la saignée 26 pratiquée dans la collerette 16 la gorge annulaire 30 dans laquelle est logé l'élément de liaison 8 tel qu'un ressort à pans. Un tel ressort est également connu sous le nom de ressort lunette car il est couramment utilisé pour le montage des lunettes tournantes de montre. A sa base, la pièce intermédiaire 10 présente un talon circulaire 40 qui vient se loger dans la rainure 20 du fond 1. La pièce intermédiaire 10 est ainsi guidée et maintenue en place radialement par la collerette annulaire 16 contre laquelle elle vient en appui par son pourtour intérieur d'une part, et par le rebord 22 contre lequel elle vient en appui par le pourtour extérieur de son talon 40 d'autre part. L'élément de liaison 8 assure quant à lui le maintien axial du fond 1 et de l'élément intermédiaire 10 comme décrit en détail ci-dessous. Par ailleurs, l'élément intermédiaire 10 présente, à l'aplomb de la rainure circulaire 20 que présente le fond 1 , un dégagement 42 qui s'étend sur pratiquement toute la circonférence dudit élément intermédiaire 10 et qui est destiné à permettre la circulation de la pièce d'entraînement 6. En un seul endroit de son périmètre, le dégagement 42 est interrompu par la butée 34 qui fait saillie dans le fond de la rainure circulaire 20. Enfin, le joint d'étanchéité 14 est disposé entre le fond 1 et la carrure 12. II est logé dans une rainure circulaire 44 pratiquée à la base de la carrure 12 et vient en appui sur le rebord 22.We now examine in more detail the intermediate element 10 and the way it allows the mounting of the bottom 1 on the middle part 12 of the watch case in connection with Figures 5 to 8. As can be seen from these figures, the element intermediate 10 is a circular-shaped piece on the outer periphery of which is machined a thread 36 intended to cooperate with a corresponding thread 38 provided on the inner periphery of the middle part 12. In the inner periphery of the intermediate piece 10 is made bleeding 28 which forms with the groove 26 formed in the collar 16 the annular groove 30 in which is housed the connecting element 8 such as a leaf spring. Such a spring is also known as a telescope spring because it is commonly used for mounting rotating watch glasses. At its base, the intermediate piece 10 has a circular heel 40 which is housed in the groove 20 of the bottom 1. The intermediate piece 10 is thus guided and held in place radially by the annular flange 16 against which it bears by its inner periphery on the one hand, and the flange 22 against which it bears by the outer periphery of its heel 40 on the other. The connecting element 8 ensures the axial retention of the bottom 1 and the intermediate element 10 as described in detail below. Furthermore, the intermediate element 10 has, in line with the circular groove 20 that has the bottom 1, a clearance 42 which extends over substantially the entire circumference of said intermediate element 10 and which is intended to allow the circulation of the driving part 6. In one place of its perimeter, the clearance 42 is interrupted by the stop 34 which protrudes into the bottom of the circular groove 20. Finally, the seal 14 is disposed between the bottom 1 and the middle part 12. It is housed in a circular groove 44 made at the base of the middle part 12 and bears on the flange 22.
Dans ce qui suit, on considérera que la pièce d'entraînement 6 est une bille et que l'élément de liaison 8 est un ressort à pans. Il va de soi que ces exemples sont donnés à titre purement illustratif seulement et que d'autres types d'organes d'entraînement et de liaison peuvent être envisagés.In what follows, it will be considered that the driving part 6 is a ball and that the connecting element 8 is a leaf spring. It goes without saying that these examples are given purely for illustrative purposes only and that other types of driving and connecting members may be envisaged.
Le montage du dispositif de fixation 4 selon l'invention s'opère de la façon suivante. Le ressort à pans 8 est inséré dans la saignée 28 que présente la pièce intermédiaire 10. Un tel ressort, de forme polygonale, est préférentiellement constitué d'une seule spire qui s'inscrit sensiblement dans un cercle. Il est formé d'une succession de segments rectilignes ou pans 8' disposés de biais les uns par rapport aux autres. Une fois le ressort 8 inséré dans la saignée 28 et la bille 6 disposée dans l'évidemment oblong 2, on enfile l'ensemble formé par l'élément intermédiaire 10 et son ressort 8 sur la collerette annulaire 16. Ce mouvement s'interrompt lorsque l'élément intermédiaire 10 arrive en butée avec son talon 40 contre le fond de la rainure 20. A ce moment là, les deux saignées 26 et 28 sont en regard et le ressort 8 peut reprendre sa position de repos dans la gorge annulaire ainsi formée. Dans cette position, le sommet entre deux segments 8' immédiatement successifs du ressort 8 est par exemple en appui contre l'élément intermédiaire 10 tandis que le milieu de chacun des segments 8' qui précède et suit le sommet est en appui contre la collerette annulaire 16. Un tel agencement rend le fond 1 totalement indissociable de l'élément intermédiaire 10 après montage. Le fond 1 conserve toutefois la possibilité de tourner relativement à l'élément intermédiaire 10.The mounting of the fixing device 4 according to the invention takes place in the following manner. The leaf spring 8 is inserted into the groove 28 that the intermediate piece 10 presents. Such a spring, of polygonal shape, preferably consists of a single turn that is substantially in a circle. It is formed of a succession of rectilinear segments or sections 8 'arranged obliquely with respect to each other. Once the spring 8 inserted into the groove 28 and the ball 6 disposed in the oblong slot 2, the assembly formed by the intermediate element 10 and its spring 8 on the annular flange 16. This movement stops when the intermediate element 10 comes into abutment with its heel 40 against the bottom of the groove 20. At that moment, the two grooves 26 and 28 are facing and the spring 8 can resume its rest position in the annular groove thus formed. In this position, the vertex between two segments 8 'immediately successive spring 8 is for example in abutment against the intermediate element 10 while the middle of each of the segments 8' which precedes and follows the top bears against the annular flange 16. Such an arrangement makes the bottom 1 completely inseparable from the intermediate element 10 after assembly. The bottom 1 retains the possibility of turning relative to the intermediate element 10.
Une fois le fond 1 et l'élément intermédiaire 10 assemblés de façon indissociable, cet ensemble est vissé sur la carrure 12 par le biais des filetages 36 et 38. On commence à visser l'ensemble formé par le fond 1 et l'élément intermédiaire 10 au moyen de la clé de serrage. Le fond 1 et l'élément intermédiaire 10 tournent ensemble aussi longtemps que les forces de frottement induites par le ressort 8 entre ledit fond 1 et ledit élément intermédiaire 10 sont supérieures au couple de serrage dudit élément intermédiaire 10 sur la carrure 12. Une fois que le couple de serrage devient supérieur aux forces de frottement engendrées par le ressort 8, l'élément intermédiaire 10 s'immobilise et le fond 1 continue de tourner relativement audit élément intermédiaire 10. En tournant, le fond entraîne la bille 6 qui se trouve en butée en fond de l'évidemment oblong 2. On continue de faire tourner le fond 1 relativement à l'élément intermédiaire 10 jusqu'à ce que la bille 6 vienne buter contre la butée 34 dudit élément intermédiaire 10 qui fait saillie dans le fond de la rainure circulaire 20. A ce moment là, le fond 1 et l'élément intermédiaire 10 sent à nouveau couplés en rotation et en faisant tourner le fond 1 , on imprime à l'élément intermédiaire 10 un couple de serrage qui permet de visser à fond cet élément intermédiaire 10 sur la carrure 12. Le vissage s'interrompt lorsque l'élément intermédiaire 10 arrive en position de blocage sur la carrure 12. Pour régler l'alignement du fond 1 par rapport à l'axe 12h-6h de la montre, il suffit ensuite de faire tourner celui-ci en sens inverse du sens de vissage. On peut tourner le fond de plus de 360° car la somme du diamètre de la bille 6 et de la longueur de la butée 34 est inférieure à la longueur de l'évidemment oblong 2. Bien entendu, le couple à exercer pour régler l'alignement du fond 1 doit être inférieur au couple de serrage de l'élément intermédiaire 10 sur la carrure 12. Ce couple doit toutefois être suffisamment élevé pour que l'on ne puisse dérégler l'alignement du fond 1 la main. Ce couple est déterminé par le joint d'étanchéité 14 disposé entre le fond 1 et la carrure 12. On estime qu'un taux de compression du joint d'étanchéité 14 d'au moins 10% est nécessaire pour atteindre les objectifs requis. On notera que le couple de frottement peut être réglé à volonté selon le type de construction envisagé. Pour dévisser l'ensemble formé par le fond 1 et l'élément intermédiaire 10, il suffit de continuer à tourner le fond 1 dans le sens contraire du vissage jusqu'à tant que la bille 6 vienne à nouveau buter contre la butée 34. Par suite, le fond 1 entraîne à nouveau l'élément intermédiaire 10 en rotation mais cette fois dans le sens du dévissage.Once the bottom 1 and the intermediate element 10 assembled inseparably, this assembly is screwed on the middle part 12 by means of the threads 36 and 38. It begins to screw the assembly formed by the bottom 1 and the intermediate element 10 using the wrench. The bottom 1 and the intermediate element 10 rotate together as long as the frictional forces induced by the spring 8 between said bottom 1 and said intermediate element 10 are greater than the tightening torque of said intermediate element 10 on the middle part 12. Once the tightening torque becomes greater than the frictional forces generated by the spring 8, the intermediate element 10 stops and the bottom 1 continues to rotate relative to said intermediate element 10. By turning, the bottom drives the ball 6 which is in abutment at the bottom of the elongate oblong 2. The bottom 1 is continued to rotate relative to the intermediate element 10 until the ball 6 abuts against the abutment 34 of said intermediate element 10 which projects into the bottom of the circular groove 20. At this time, the bottom 1 and the intermediate element 10 are coupled again in rotation and by rotating the bottom 1, it prints at once. the intermediate element 10 a tightening torque which makes it possible to screw this intermediate element 10 fully to the middle part 12. The screwing stops when the intermediate element 10 reaches the locking position on the middle part 12. To adjust the alignment of the bottom 1 with respect to the axis 12h-6h of the watch, it is then sufficient to turn it in the opposite direction of the screwing direction. The bottom can be rotated by more than 360 ° because the sum of the diameter of the ball 6 and the length of the stop 34 is less than the length of the elongate oblong 2. Of course, the torque to be exerted to adjust the alignment of the bottom 1 must be less than the tightening torque of the intermediate element 10 on the middle 12. This torque must however be high enough so that one can not disrupt the alignment of the bottom 1 hand. This torque is determined by the seal 14 disposed between the bottom 1 and the middle part 12. It is estimated that a compression ratio of the seal 14 of at least 10% is necessary to achieve the required objectives. It will be noted that the friction torque can be adjusted at will according to the type of construction envisaged. To unscrew the assembly formed by the bottom 1 and the intermediate element 10, simply continue to turn the bottom 1 in the opposite direction of the screwing until the ball 6 comes again abut against the stop 34. By following, the bottom 1 again drives the intermediate element 10 in rotation but this time in the direction of unscrewing.
Les figures 10 à 12 sont des vues en coupe d'une variante de réalisation du dispositif de fixation 4 selon l'invention. Conformément à cette variante, l'élément de liaison 8 se présente sous la forme d'une bague 46 chassée entre la collerette annulaire 16 du fond 1 et l'élément intermédiaire 10. Plus précisément, la bague 46 vient en appui sur un épaulement annulaire 48 ménagé sur le pourtour intérieur de l'élément intermédiaire 10 et présente elle-même sur son pourtour intérieur un plan incliné 50 qui coopère avec un plan incliné 52 correspondant pratiqué sur le pourtour extérieur de la collerette 16 et qui permet le couplage axial entre le fond 1 et l'élément intermédiaire 10 par effet de coin.Figures 10 to 12 are sectional views of an alternative embodiment of the fixing device 4 according to the invention. According to this variant, the connecting element 8 is in the form of a ring 46 driven between the annular flange 16 of the bottom 1 and the intermediate element 10. More specifically, the ring 46 bears on an annular shoulder 48 formed on the inner periphery of the intermediate element 10 and itself has on its inner periphery an inclined plane 50 which cooperates with a corresponding inclined plane 52 formed on the outer periphery of the flange 16 and which allows the axial coupling between the bottom 1 and the intermediate element 10 by corner effect.
Il va de soi que la présente invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits 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 embodiments which have just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims.
