Description

La présente invention a pour objet un dispositif de fixation pour timbres d'une montre à sonnerie, en particulier un dispositif destiné à être agencé contre la glace fermant le boîtier d'une telle pièce d'horlogerie.The present invention relates to a fixing device for timbres of a striking watch, in particular a device intended to be arranged against the ice closing the case of such a timepiece.

Les montres à sonnerie sont dotées d'un organe générateur de sons pouvant produire une ou plusieurs ondes acoustiques de différentes tonalités, destinées à se propager au-delà du boîtier de la montre. Typiquement, l'organe vibrant au sein du boîtier peut être un timbre générant de telles ondes après avoir été frappé par le marteau du mécanisme de sonnerie.Bell watches have a sound generator that can produce one or more acoustic waves of different tones, intended to spread beyond the watch case. Typically, the vibrating member within the housing may be a stamp generating such waves after being struck by the hammer striking mechanism.

Le timbre d'une montre-bracelet est généralement constitué d'un brin métallique de section circulaire ou d'une lame métallique formant un enroulement autour du mouvement de la montre. La longueur de cet enroulement détermine la tonalité souhaitée.The stamp of a wristwatch is generally made of a metallic strand of circular section or a metal blade forming a winding around the movement of the watch. The length of this winding determines the desired tone.

Fortement fixé en l'une de ses extrémités sur laquelle vient frapper le marteau, le timbre se trouve ainsi supporté par un sabot généralement solidaire du mouvement ou de la carrure de la montre.Strongly fixed at one of its ends on which the hammer hits, the stamp is thus supported by a shoe generally integral with the movement or the middle part of the watch.

Pour pouvoir pleinement bénéficier de leur fonction sonore, il convient de réaliser des montres capables de produire des sons clairement audibles. Si cette caractéristique ne pose généralement que peu de problèmes pour les montres dites de poche ou pour les montres de plus grands formats, en revanche il n'en va pas de même pour les montres de taille beaucoup plus petite telles que les montres-bracelet pour lesquelles l'objet de la présente invention est préférentiellement destiné.To fully benefit from their sound function, it is necessary to make watches capable of producing clearly audible sounds. While this feature generally poses few problems for so-called pocket watches or larger size watches, the same is not true for watches of much smaller size such as wristwatches. which object of the present invention is preferentially intended.

L'espace restreint mis à disposition dans les boîtes de ces montres conditionne directement la taille des multiples pièces qui constituent son mouvement. Cette miniaturisation affecte la quantité d'énergie qu'une telle montre est en mesure de fournir et porte finalement préjudice aux capacités acoustiques des organes générateurs de sons. Le boîtier de ces montres constitue lui-même le premier élément qui empêche la propagation des ondes sonores vers l'extérieur. Cet inconvénient se trouve accentué par la présence de joints d'étanchéité dont est dotée la grande majorité des boites de montres-bracelet, en particulier à l'interface de la glace et de la lunette ainsi qu'entre la carrure et le fond du boîtier. Ce dernier peut également être fermé par une glace côté fond pour offrir une vue sur le mouvement depuis l'extérieur.The limited space available in the boxes of these watches directly determines the size of the multiple pieces that make up his movement. This miniaturization affects the amount of energy that such a watch is able to provide and ultimately damages the acoustic capabilities of the sound generating organs. The case of these watches is itself the first element that prevents the propagation of sound waves to the outside. This disadvantage is accentuated by the presence of seals which is endowed with the great majority of the wristwatch boxes, in particular at the interface of the glass and the bezel as well as between the middle and the bottom of the case. . The latter can also be closed by a side ice to provide a view of the movement from the outside.

Pour améliorer la propagation du son au travers du boîtier, il est connu de fixer le sabot porteur des timbres sur le mouvement et d'y adjoindre un appui sur la glace, côté fond ou côté cadran.To improve the propagation of sound through the housing, it is known to fix the stamp bearing shoe on the movement and to add a support on the ice, bottom side or dial side.

Suivant d'autres systèmes de fixation, il est suggéré de monter le sabot sur cette glace, par collage ou par soudage.According to other fastening systems, it is suggested to mount the shoe on this ice, by gluing or welding.

Qu'elle soit montée côté cadran ou côté fond, la glace constitue dans tous les cas une pièce destinée à clore le boîtier, lequel, dans la majorité des cas, requiert d'être à l'abri des poussières et de l'eau afin de protéger efficacement le mouvement et les timbres.Whether mounted on the dial side or the bottom side, the ice is in all cases a piece intended to close the case, which, in the majority of cases, requires to be protected from dust and water so to effectively protect the movement and the stamps.

L'objet de la présente invention a pour but d'améliorer la transmission des ondes sonores qui, de façon importante, conditionne aussi bien l'intensité du son perçu à l'extérieur du boîtier que la qualité acoustique des ondes restituées par ce dernier.The object of the present invention is to improve the transmission of sound waves which, importantly, conditions both the intensity of sound perceived outside the housing and the acoustic quality of the waves returned by the latter.

A cet effet, la présente invention a pour objet un dispositif de fixation d'un support de timbres conforme à ce qu'énonce la revendication 1.For this purpose, the subject of the present invention is a device for fixing a stamp holder according to claim 1.

Pour ce faire, il est suggéré un dispositif de fixation pour timbres destiné à être agencé en appui contre la glace fermant le boîtier de la montre. Le présent dispositif comprend un support ou sabot pouvant immobiliser au moins une extrémité d'un timbre au sein du boîtier, ainsi qu'un moyen de fixation de ce sabot contre la glace. Selon l'invention, ce moyen de fixation est un moyen de fixation par serrage permettant au sabot d'engendrer une pression contre la glace. Délivrée à demeure par une force de serrage appliquée sur ces deux pièces, cette pression permet avantageusement d'accentuer le rendu de l'intensité et de la qualité des ondes acoustiques transmises au travers du boîtier.To do this, it is suggested a fixing device for stamps intended to be arranged in support against the ice closing the case of the watch. The present device comprises a support or shoe that can immobilize at least one end of a stamp within the housing, and a means for fixing the shoe against the ice. According to the invention, this fastening means is a fastening means by clamping allowing the shoe to generate a pressure against the ice. Permanently delivered by a clamping force applied to these two parts, this pressure advantageously makes it possible to accentuate the rendering of the intensity and the quality of acoustic waves transmitted through the housing.

Selon le mode de réalisation préféré, le moyen de fixation par serrage intègre un moyen de réglage qui permet un ajustement de la force d'assemblage appliquée entre le sabot et la glace.According to the preferred embodiment, the clamping fastening means includes adjustment means which allows adjustment of the assembly force applied between the shoe and the ice.

Avantageusement, l'effet de serrage dispensé par ce moyen est réversible. Ainsi, il devient aussi aisé d'assembler que de séparer le sabot de la glace une fois ceux-ci accouplés.Advantageously, the clamping effect dispensed by this means is reversible. Thus, it becomes as easy to assemble as to separate the shoe from the ice once they are coupled.

Contrairement a une idée reçue selon laquelle la ou les glaces de fermeture du boîtier de la montre ne devraient pas être percées, l'invention suggère de préférence que le moyen de fixation par serrage traverse la glace par le biais d'au moins un trou ménagé dans l'épaisseur de celle-ci.Contrary to popular belief that the closing window (s) of the watch case should not be pierced, the invention preferably suggests that the clamping means passes through the ice through at least one hollow hole. in the thickness of it.

Ainsi, le moyen de fixation par serrage comprend de préférence au moins un organe fileté pourvu, en l'une de ses extrémités, d'une collerette ou d'une surface d'appui en contact avec la face extérieure de la glace. Cet organe est destiné à venir se visser avec une portion filetée sise dans le sabot utile au maintien des extrémités des timbres.Thus, the clamping means preferably comprises at least one threaded member provided at one of its ends with a flange or a bearing surface in contact with the outer face of the ice. This body is intended to be screwed with a threaded portion located in the shoe useful in maintaining the ends of the stamps.

Avantageusement, l'agencement d'un tel moyen permet, dans une plage allant de la limite du serrage à la rupture mécanique des pièces en jeu, d'engendrer une pression d'intensité variable entre le sabot et la glace.Advantageously, the arrangement of such a means makes it possible, in a range from the limit of the clamping to the mechanical break of the parts involved, to generate a pressure of variable intensity between the shoe and the ice.

La boîte de montre peut néanmoins être maintenue étanche aux liquides et aux fines particules de poussières, grâce à l'adjonction d'au moins un joint d'étanchéité disposé à l'interface de la glace et de la surface d'appui associé à l'organe fileté qui la traverse.The watch case can nevertheless be kept impervious to liquids and fine dust particles by adding at least one seal disposed at the interface of the ice and the bearing surface associated with the threaded member which passes through it.

D'autres avantages et spécificités apparaîtront à la lumière de la description qui va suivre et qui se réfère à un mode de réalisation préféré de l'objet de l'invention ainsi qu'à des variantes, pris à titre nullement limitatif et illustrés schématiquement et à titre d'exemple par les figures annexées dans lesquelles:

D'un point de vue terminologique, on mentionnera que le présent exposé fait référence à l'utilisation sans distinction des termes boîtier et boîte de montre. Aussi, on précisera que la glace utile à la fermeture du boîtier peut être indistinctement celle disposée au-dessus, côté cadran, ou au-dessous, côté fond.From a terminological point of view, it will be mentioned that the present description refers to the use without distinction of the terms case and watch case. Also, it will be specified that the useful ice closure of the housing can be indistinctly that disposed above, dial side, or below, bottom side.

En référence à la figure 1, celle-ci représente schématiquement la face intérieure 10a d'une glace 10 destinée à fermer une boite de montre (non illustrée) pour une pièce d'horlogerie dotée d'un dispositif de sonnerie. Ce dernier est partiellement représenté ici par deux timbres T1, T2 immobilisés par au moins une de leurs extrémités 1, 2 (mieux visibles aux figures 2, 3 et 3a) dans un support dénommé sabot 20. On relèvera que le nombre de timbres ne porte aucune incidence sur l'objet de l'invention. Compris généralement entre un et trois, il ne dépend essentiellement que du type de montre à sonnerie, dont on citera en exemple les montres à répétition, les montres à grandes sonneries ou les carillons.With reference to the figure 1 , this schematically represents the inner face 10a of a window 10 for closing a watch case (not shown) for a timepiece equipped with a striking device. The latter is partially represented here by two stamps T 1 , T 2 immobilized by at least one of their ends 1, 2 (better visible at Figures 2, 3 and 3a ) in a support called shoe 20. Note that the number of stamps does not affect the subject of the invention. Generally understood as between one and three, it depends essentially only on the type of striking watch, examples of which are repeating watches, watches with loud rings or chimes.

La figure la illustre plus en détail la portion de la figure 1 entourée du cercle dessiné en trait interrompu. La figure 1b représente cette même portion de détail, mais telle qu'elle apparaît du côté de la face extérieure 10b de la glace. Comme bien illustré sur ces figures, le sabot 20 est maintenu au contact de la face intérieure 10a de la glace par un moyen de fixation 30. Ce moyen de fixation consiste en un moyen de fixation par serrage, permettant au sabot 20 d'exercer une pression constante contre la glace 10.Figure la illustrates in more detail the portion of the figure 1 surrounded by a circle drawn in broken lines. The figure 1b represents the same portion of detail, but as it appears on the side of the outer face 10b of the ice. As well illustrated in these figures, the shoe 20 is held in contact with the inner face 10a of the ice by a fastening means 30. This fastening means consists of a fastening means by clamping, allowing the shoe 20 to exert a constant pressure against ice 10.

En référence à la figure 2, celle-ci illustre le dispositif de l'invention dans une coupe verticale simplifiée, suivant la ligne II-II de la figure 1b. Le moyen de fixation 30 par serrage comprend au moins une paire d'organes filetés, à savoir au moins un premier élément ou organe fileté 31 destiné à venir en prise avec une portion filetée 32 solidaire du sabot 20. Le premier organe fileté 31 est pourvu, en l'une de ses deux extrémités, d'une tête 33 destinée à servir au moins de surface d'appui lorsque cet organe est appliqué contre la face extérieure 10b de la glace 10. Comme bien illustré dans la figure 1b, cette tête 33 présente de préférence une surface lisse, dépourvue de tout encoche ou moyen de préhension.With reference to the figure 2 , this illustrates the device of the invention in a simplified vertical section along the line II-II of the figure 1b . The way fastening device 30 comprises at least one pair of threaded members, namely at least one first element or threaded member 31 intended to engage with a threaded portion 32 integral with the shoe 20. The first threaded member 31 is provided with one of its two ends, a head 33 intended to serve at least a bearing surface when this member is applied against the outer face 10b of the mirror 10. As illustrated in FIG. figure 1b this head 33 preferably has a smooth surface, devoid of any notch or gripping means.

En revenant à la figure 2, on remarque que le filetage de ce premier organe consiste en un taraudage, ou filetage intérieur 35, ménagé dans le corps tubulaire de cet organe. Plus précisément, ce taraudage est usiné dans un trou borgne de ce corps ouvert en l'extrémité opposée à celle coiffée de la tête 33. La partie extérieure du corps de ce premier organe fileté 31 est constituée par une portée ou une surface externe 37, préférentiellement lisse et cylindrique.Returning to figure 2 it will be noted that the threading of this first member consists of a tapping, or internal thread 35, formed in the tubular body of this member. More precisely, this tapping is machined in a blind hole of this open body at the end opposite to that capped with the head 33. The outer part of the body of this first threaded member 31 is constituted by a bearing surface or an external surface 37, preferably smooth and cylindrical.

Selon la figure 2, la portion filetée 32 correspond plus particulièrement au filetage d'un second organe fileté qui se trouve de préférence entièrement noyé dans le sabot 20. De préférence encore, ce second organe consiste en une vis dont la tête 34 vient se loger au fond d'un lamage ménager à la surface libre du sabot 20.According to figure 2 , the threaded portion 32 corresponds more particularly to the threading of a second threaded member which is preferably completely embedded in the shoe 20. More preferably, this second member consists of a screw whose head 34 is housed in the bottom of a countersink at the free surface of the shoe 20.

Grâce au mode de réalisation préféré du dispositif de fixation de l'invention, ce dernier intègre un moyen de réglage 40 permettant avantageusement d'ajuster la force de serrage générant la pression entre le sabot 20 et la glace 10. Comme représenté aux figures 1a, 2, 3, 3a et 4a, ce moyen de réglage permet d'agir sur le couple constitué du premier organe fileté 31 et de la portion filetée 32 qui, le cas échéant, correspond au second organe fileté. Ce moyen de réglage consiste de préférence en une encoche offrant un moyen de préhension pour pouvoir actionner l'un ou l'autre de ces organes filetés. Selon la figure 2, ce moyen de réglage 40 est associé à la tête 34 du second organe fileté et permet de visser ou de dévisser cet organe dans le taraudage 35 du premier organe fileté 31.Thanks to the preferred embodiment of the fixing device of the invention, the latter incorporates an adjusting means 40 advantageously to adjust the clamping force generating the pressure between the shoe 20 and the ice 10. As shown in FIG. figures 1a , 2, 3, 3a and 4a this means of adjustment makes it possible to act on the torque consisting of the first threaded member 31 and the threaded portion 32 which, if necessary, corresponds to the second threaded member. This adjustment means preferably consists of a notch providing a gripping means for actuating one or other of these threaded members. According to figure 2 , this means of adjustment 40 is associated with the head 34 of the second threaded member and makes it possible to screw or unscrew this member in the tapping 35 of the first threaded member 31.

Afin de pouvoir garantir l'étanchéité de la boîte de montre, un premier joint d'étanchéité 15 est encore disposé à l'interface de la glace 10 et de la tête 33 du premier organe fileté 31. De forme circulaire et préférentiellement torique, ce joint est destiné à venir se loger à la surface extérieure 10b de la glace, dans le creux d'un chanfrein usiné sur le bord de l'ouverture circulaire destinée au passage du premier organe fileté. De préférence, le diamètre de cette ouverture circulaire est supérieur à celui du premier organe fileté de manière à obtenir un jeu utile au positionnement du sabot sur la glace, plus particulièrement, au positionnement des timbres par rapport au marteau du dispositif de sonnerie qui viendra les frapper. Ainsi, ce jeu délimite la latitude de positionnement du sabot 20 par rapport à la glace 10 contre laquelle il est destiné à venir s'appliquer par serrage.In order to be able to guarantee the tightness of the watch case, a first seal 15 is still disposed at the interface of the lens 10 and the head 33 of the first threaded member 31. Of a circular shape and preferably of a ring, this seal is intended to be housed on the outer surface 10b of the ice, in the hollow of a chamfer machined on the edge of the circular opening for the passage of the first threaded member. Preferably, the diameter of this circular opening is greater than that of the first threaded member so as to obtain a clearance useful for the positioning of the shoe on the ice, more particularly, the positioning of the stamps relative to the hammer of the striking device which will come to them. hit. Thus, this game defines the positioning latitude of the shoe 20 relative to the ice 10 against which it is intended to be applied by clamping.

Les timbres T1 et T2 sont chacun maintenus dans le sabot 20 par insertion d'une de leurs extrémités 1, 2 respectives dans un trou d'axe parallèle à celui du plan de la glace 10. De préférence, ce trou est encore situé dans le plan vertical médian du sabot 20, conformément à la vue en coupe de la figure 2.The timbres T1 and T2 are each held in the shoe 20 by insertion of one of their respective ends 1, 2 in a hole of axis parallel to that of the plane of the ice 10. Preferably, this hole is still located in the median vertical plane of the shoe 20, in accordance with the sectional view of the figure 2 .

La figure 3 se réfère à une variante du moyen de fixation 30 illustré aux figures 1a, 1b et 2. Selon cet autre mode de réalisation, on remarque que le moyen de réglage 40 est associé à la tête 33 du premier organe fileté. En particulier, le moyen de réglage 40 consiste en une gorge ou une rainure, comparable ou identique à celle illustrée à la figure 1a, permettant d'y insérer un outil pour procéder au serrage qui convient. Bien entendu, il serait également possible de prévoir des ergots ou des trous en remplacement d'une telle encoche.The figure 3 refers to a variant of the fixing means 30 illustrated in FIGS. Figures 1a, 1b and 2 . According to this other embodiment, it is noted that the adjustment means 40 is associated with the head 33 of the first threaded member. In particular, the adjusting means 40 consists of a groove or a groove, comparable or identical to that illustrated in FIG. figure 1a , allowing to insert a tool to proceed to the appropriate tightening. Of course, it would also be possible to provide lugs or holes to replace such a notch.

Bien qu'aucun jeu ne soit illustré dans cette figure entre le premier organe fileté et l'ouverture ménagée pour son passage au travers de la glace, on comprendra que le couple d'organes filetés représenté ici en variante pourrait tout aussi bien remplir sa fonction en présence d'un tel jeu.Although no clearance is shown in this figure between the first threaded member and the opening formed for its passage through the ice, it will be understood that the pair of threaded members shown here alternatively could just as well fulfill its function in the presence of such a game.

Le second organe fileté illustré dans cette figure 3 consiste plus précisément en un tourillon dont une première partie 36 de sa longueur est pourvue d'un filetage. Par ce biais, le premier organe fileté 31 peut venir s'y visser. La seconde partie 38 du tourillon vise à empêcher toute rotation du second organe fileté dans l'ouverture 21 prévue dans le sabot 20 pour y recevoir le second organe fileté. Bien qu'illustrée traversante, cette ouverture 21 pourrait consister en un trou borgne, ouvert du côté de la glace. Le blocage en rotation de cet organe peut par exemple être obtenu par une clavette. En variante, un tel blocage pourrait être obtenu par vissage de la seconde partie 38 dans un taraudage usiné dans l'ouverture 21 ou encore au moyen d'un système à baïonnette, voire par serrage, en y chassant cette seconde partie.The second threaded member illustrated in this figure 3 more precisely consists of a trunnion of which a first portion 36 of its length is provided with a thread. By this means, the first threaded member 31 can come to screw. The second part 38 of the pin aims to prevent any rotation of the second threaded member in the opening 21 provided in the shoe 20 to receive the second threaded member. Although illustrated through, this opening 21 could consist of a blind hole, open on the side of the ice. The locking in rotation of this member can for example be obtained by a key. Alternatively, such locking could be obtained by screwing the second portion 38 into a thread machined in the opening 21 or by means of a bayonet system, or by clamping, by chasing this second part.

D'une façon identique ou similaire, il serait également possible de bloquer en rotation le premier organe fileté décrit dans le mode de réalisation préféré se référant à la figure 2.In an identical or similar manner, it would also be possible to lock in rotation the first threaded member described in the preferred embodiment referring to the figure 2 .

La figure 3a représente une variante du dispositif de la figure 3 dans laquelle le premier organe fileté 31 est dépourvu de filetage intérieur mais comprend un filetage extérieur 35'. Ce dernier est disposé à l'extrémité de la surface externe 37 de cet organe. Ainsi, cette surface externe comprend d'une part, une portée lisse destinée à venir se situer dans l'épaisseur de la glace 10 et d'autre part, une portée filetée en l'extrémité opposée à la tête 33. La portée filetée a pour but de venir se visser dans la portion filetée 32 qui, dans ce cas, consiste en un taraudage ménagé directement dans le sabot 20, par exemple dans un trou borgne 21'.The figure 3a represents a variant of the device of the figure 3 wherein the first threaded member 31 is devoid of internal thread but includes an external thread 35 '. The latter is disposed at the end of the outer surface 37 of this member. Thus, this external surface comprises on the one hand a smooth surface intended to be situated in the thickness of the window 10 and, on the other hand, a threaded surface at the end opposite the head 33. The threaded surface has intended to screw itself into the threaded portion 32 which, in this case, consists of a tapping formed directly in the shoe 20, for example in a blind hole 21 '.

Le dispositif de fixation de la présente invention intégrera encore de préférence un moyen de positionnement du sabot 20 contre la glace 10, en particulier contre la surface interne 10a de cette glace. Dans le mode de réalisations illustré à la figure 3, ce moyen de positionnement est obtenu par un alésage 50 ménagé au sein du sabot 20, dans le prolongement de l'ouverture 21, 21' utile à l'insertion du second organe fileté. Cet alésage permet de recevoir, sans jeu, l'extrémité libre de la surface externe 37 du premier organe fileté. Par emboîtement de cette surface externe dans l'alésage 50, le sabot 20 peut être positionné de façon précise contre glace 10. Un positionnement relatif entre le sabot et la glace pourra être garanti par un tel moyen pour autant qu'il n'existe aucun jeu entre le premier organe fileté et l'ouverture circulaire destinée à son passage au travers de la glace.The fastening device of the present invention will further preferably incorporate means for positioning the shoe 20 against the ice 10, in particular against the inner surface 10a of this ice. In the embodiment shown in figure 3 this positioning means is obtained by a bore 50 formed in the shoe 20, in the extension of the opening 21, 21 'useful for the insertion of the second threaded member. This bore allows to receive, without play, the free end of the outer surface 37 of the first threaded member. By interlocking this outer surface in the bore 50, the shoe 20 can be accurately positioned against ice 10. A relative positioning between the shoe and the ice can be guaranteed by such means provided that there is no clearance between the first threaded member and the circular opening for its passage through the ice.

En variante, il serait également possible d'obtenir un positionnement identique par un système d'emboîtement d'une bille dans une cavité, voire d'un ergot ou d'une douille dans un perçage.Alternatively, it would also be possible to obtain identical positioning by a system for fitting a ball into a cavity, or even a pin or a socket in a bore.

En référence aux figures 4a et 4b, celles-ci illustrent encore un autre mode de réalisation du dispositif représenté aux figures 2 et 1b respectives. La figure 4a correspond à une vue en coupe verticale simplifiée selon la ligne III-III de la figure 4b. On y remarque l'adjonction d'une collerette 13 disposée entre la glace 10 et la surface d'appui associée au premier organe fileté 31, en l'occurrence la tête 33. Ainsi, cette dernière se trouve être en appui contre la glace par l'intermédiaire de la collerette 13 qui vise à étendre la surface de contact sur la face extérieur 10b de la glace afin de réduire la pression exercée sur cette dernière.With reference to Figures 4a and 4b , these still illustrate another embodiment of the device shown in figures 2 and 1b respectively. The figure 4a corresponds to a simplified vertical sectional view along line III-III of the figure 4b . It is noted the addition of a flange 13 disposed between the ice 10 and the bearing surface associated with the first threaded member 31, in this case the head 33. Thus, the latter is supported against the ice by through the flange 13 which aims to extend the contact surface on the outer face 10b of the ice to reduce the pressure exerted on the latter.

Dans une telle configuration, un second joint d'étanchéité 15' est disposé à l'interface de la glace 10 et de la collerette 13 alors que le premier joint d'étanchéité 15 est dans ce cas situé à l'interface de la collerette 13 et de la tête 33. Ce second joint 15' est destiné à prendre place dans une gorge ménagée à la surface intérieure de la collerette 13 suivant une courbe fermée qui entoure la ou les ouvertures destinées au passage du ou des premiers organes filetés 31.In such a configuration, a second seal 15 'is disposed at the interface of the lens 10 and the collar 13 while the first seal 15 is in this case located at the interface of the collar 13 and the head 33. This second seal 15 'is intended to take place in a groove formed on the inner surface of the flange 13 along a closed curve which surrounds the opening or openings intended for the passage of the first threaded member (s) 31.

Comme représenté sur les figures 4a et 4b dans lesquelles le moyen de fixation 30 par serrage comprend deux paires d'organes filetés 31, 32, la collerette 13 fait office de pont entre les deux têtes 33 en leur procurant ainsi une assise commune.As shown on Figures 4a and 4b wherein the clamping means 30 comprises two pairs of threaded members 31, 32, the flange 13 acts as a bridge between the two heads 33 thereby providing a common seat.

Selon les modes de réalisation décrits dans le présent exposé, il a été prévu que la force de serrage soit obtenue par vissage d'un organe fileté. Cependant, on relèvera que d'autres moyens mécaniques permettraient également d'obtenir le même effet. En exemple, on mentionnera que cette force de serrage pourrait être obtenue par rotation d'un excentrique ou encore par basculement d'un petit bras de levier articulé.According to the embodiments described in the present disclosure, it has been provided that the clamping force is obtained by screwing a threaded member. However, it will be noted that other mechanical means would also make it possible to obtain the same effect. As an example, it should be mentioned that this clamping force could be obtained by rotating an eccentric or by tilting a small articulated lever arm.

Comme illustré dans les figures annexées, le dispositif de fixation 30 comprend deux couples constitués chacun d'un premier organe fileté 31 et d'une portion filetée 32. Cependant, on comprendra que le nombre de ces couples pourrait bien entendu être différent.As illustrated in the accompanying figures, the fixing device 30 comprises two pairs each consisting of a first threaded member 31 and a threaded portion 32. However, it will be understood that the number of these couples could of course be different.
