Description

La présente invention concerne d'une façon générale les projecteurs de véhicules automobiles, et plus particulièrement un projecteur équipé d'une lampe dont l'axe est orienté perpendiculairement à l'axe optique de son miroir.The present invention relates generally automotive headlights, and more particularly a projector equipped with a lamp whose the axis is oriented perpendicular to the optical axis of his mirror.

On sait déjà qu'une telle orientation de lampe apporte dans un projecteur certains avantages. En particulier, la zone de fond du miroir devient utilisable pour la formation du faisceau, ce qui est particulièrement intéressant dans le cas de miroirs capables d'engendrer par eux-mêmes des faisceaux ayant la photométrie requise, tels que des faisceaux à coupure, en particulier des faisceaux antibrouillard.We already know that such a lamp orientation brings certain advantages to a projector. In particular, the bottom area of the mirror becomes usable for beam formation, which is particularly interesting in the case of mirrors able to generate by themselves beams having the photometry required, such as cutting beams, in especially fog beams.

Un autre avantage de ce type de projecteur connu réside en ce que l'accès à la lampe pour son remplacement, par le dessus, ou par le côté du projecteur, voire par le dessous, peut être facilité dans certains types de configurations.Another advantage of this known type of projector resides in that access to the lamp for its replacement, from above, or from the side of the projector, or even from below, can be facilitated in certain types of configurations.

Le document FR-A-2 701 539 donne un exemple d'un tel projecteur.Document FR-A-2 701 539 gives an example of such a projector.

Ce projecteur connu présente toutefois l'inconvénient de nécessiter, pour le montage de la lampe, un porte-lampe spécial qui est monté sur des aménagements appropriés du miroir et qui comporte des aménagements propres pour la réception de la lampe.This known projector presents however the disadvantage of requiring, for mounting the lamp, a special lamp holder which is mounted on appropriate mirror fittings which include clean fittings for receiving the lamp.

La présence d'un tel porte-lampe accroít le coût de revient du projecteur et le temps nécessaire à son montage.The presence of such a lamp holder increases the cost of comes back from the projector and the time it takes to mounting.

Le remplacement de la lampe est également plus fastidieux, puisqu'il est nécessaire de retirer le porte-lampe, de remplacer la lampe puis de remettre le porte-lampe en place. Lamp replacement is also more tedious, since it is necessary to remove the lamp holder, replace the lamp and then replace the lamp holder in place.

En outre, un tel porte-lampe peut être visible à travers la glace du projecteur, et nuire à son aspect lorsqu'il est éteint.In addition, such a lamp holder can be visible at through the lens of the projector, and detract from its appearance when it is off.

La présente invention vise à pallier les inconvénients de l'état de la technique, et à proposer un projecteur à lampe transversale dans lequel la lampe puisse être montée directement sur des aménagements appropriés du miroir et puisse être aisément remplacée, ceci sans compromettre ou rendre particulièrement délicate la réalisation de ce miroir par moulage.The present invention aims to overcome the disadvantages of the state of the art, and to propose a projector with transverse lamp in which the lamp can be mounted directly on fittings suitable for the mirror and can be easily replaced, this without compromising or rendering particularly delicate the realization of this mirror by molding.

La réalisation des miroirs modernes par moulage est en effet un élément important pour la qualité du produit et le coût de revient et l'efficacité de sa fabrication, et ne doit pas être compromise sous seul prétexte de l'économie d'une pièce que constituait le porte-lampe dans l'art antérieur.The realization of modern mirrors by molding is indeed an important element for product quality and the cost price and the efficiency of its manufacture, and should not be compromised on the sole pretext of the economy of a room that constituted the lamp holder in the prior art.

Ainsi la présente invention propose un projecteur de véhicule automobile, comprenant une lampe montée dans un miroir et une glace de fermeture, la lampe possédant des aménagements d'appui dans un plan perpendiculaire à son axe et étant montée dans le miroir avec son axe perpendiculaire à un axe optique du miroir, et le miroir étant réalisé par injection de matière plastique en étant démoulé selon une direction parallèle audit axe optique, et le miroir possédant au moins une joue adjacente à une zone de fond, caractérisé en ce qu'un trou de lampe est formé directement dans ladite joue, en ce qu'une surface extérieure d'une paroi du miroir entourant le trou de lampe présente par rapport à la direction de démoulage un angle de dépouille, et en ce qu'il est prévu entre ladite surface et lesdits aménagements d'appui de la lampe des moyens d'adaptation formant pour lesdits aménagements d'appui de la lampe des surfaces d'appui s'étendant dans un plan parallèle audit axe optique.Thus the present invention provides a searchlight motor vehicle, comprising a lamp mounted in a mirror and a closing glass, the lamp having supporting arrangements in a plane perpendicular to its axis and being mounted in the mirror with its axis perpendicular to an optical axis of the mirror, and the mirror being made by injecting plastic material by being demolded in a direction parallel to said optical axis, and the mirror having at least one cheek adjacent to a bottom area, characterized in that a lamp hole is formed directly in said cheek, in that a surface exterior of a wall of the mirror surrounding the hole of lamp present in relation to the demolding direction a clearance angle, and in that it is provided between said surface and said lamp support arrangements of the adaptation means forming for said arrangements lamp support bearing surfaces extending into a plane parallel to said optical axis.

    • En référence tout d'abord aux figures 1 à 3, on a représenté un projecteur qui comprend une lampe 10 et un miroir 20, ainsi que, de façon bien connue et non représentée, une glace et le cas échéant un boítier.Referring first to Figures 1 to 3, we have shown a projector which includes a lamp 10 and a mirror 20, as well as, in a well known manner and not shown, a glass and if necessary a case.

    La lampe 10 comprend un filament 11 selon son axe à l'intérieur d'un bulbe 12, et un culot 13, un connecteur d'alimentation 14 étant également illustré.The lamp 10 comprises a filament 11 along its axis at the inside of a bulb 12, and a base 13, a connector supply 14 also being illustrated.

    Le miroir comprend une partie de fond 21 apte à coopérer avec la lampe pour engendrer un faisceau de photométrie souhaitée, par exemple un faisceau antibrouillard, et deux joues 22, 23. Il s'agit en l'espèce de joues latérales, mais il pourrait s'agir également de joues supérieure et inférieure.The mirror includes a bottom part 21 able to cooperate with the lamp to generate a beam of desired photometry, for example a fog beam, and two cheeks 22, 23. This is the case side cheeks, but it could also be upper and lower cheeks.

    Dans la région de la joue 22 adjacente au fond 21 est formé un dispositif de montage 200 pour la lampe 10.In the cheek region 22 adjacent to the bottom 21 a mounting device 200 is formed for the lamp 10.

    On observera ici que la réalisation du miroir par moulage implique le recours à une cavité de moule et à un poinçon de moule dont les surfaces présentent par rapport à la direction de démoulage un angle de dépouille, qui est ici révélé par l'inclinaison des joues 22 et 23 par rapport à l'axe optique x-x du miroir qui correspond à la direction de démoulage.We will observe here that the realization of the mirror by molding involves the use of a mold cavity and a mold punch whose surfaces have relative to to the demolding direction a draft angle, which is here revealed by the inclination of the cheeks 22 and 23 by relation to the optical axis x-x of the mirror which corresponds to the demoulding direction.

    Sachant qu'une lampe conventionnelle occupe sa position de référence par appui de sa collerette contre un plan perpendiculaire à l'axe de ladite lampe, on comprend donc que, si l'on souhaite donner à la lampe 10 une orientation perpendiculaire à l'axe optique x-x, alors se pose inévitablement le problème du démoulage de la surface d'appui précitée, qui devrait alors s'étendre parallèlement à l'axe optique x-x, c'est-à-dire à la direction de démoulage, et donc ne pas comporter l'angle de dépouille nécessaire.Knowing that a conventional lamp occupies its reference position by pressing its flange against a plane perpendicular to the axis of said lamp, we therefore understands that if we wish to give the lamp 10 an orientation perpendicular to the optical axis x-x, then inevitably arises the problem of demolding the aforementioned bearing surface, which should then extend parallel to the optical axis x-x, that is to say to the demolding direction, and therefore does not include the angle clearance required.

    Selon l'invention, le porte-lampe 200 est défini en premier lieu par des aménagements particuliers venus de moulage lors de la fabrication du miroir. Ces aménagements comprennent pour l'essentiel une cavité dont le fond est défini par une paroi 201 suivant un angle de dépouille par exemple de 7° et délimitée en outre par une paroi latérale 202 en forme générale de « U ». Dans la paroi de fond 201 est formée une ouverture traversante 204 destinée au passage de la lampe, ouverture dont la dimension est telle que la paroi de fond 201 forme un épaulement sensiblement tout autour d'elle. La paroi de fond 201 possède par ailleurs de façon localisée autour de l'ouverture 204 trois plots discrets d'appui 2011, 2012 et 2013 pour trois bossages de référence prévus sur la collerette d'une lampe normalisée telle qu'une lampe de type « H1 », « H4 » ou « H7 ».According to the invention, the lamp holder 200 is defined in first place by special arrangements from molding during the manufacture of the mirror. These facilities essentially include a cavity, the bottom is defined by a wall 201 at an angle of strikes for example by 7 ° and further delimited by a side wall 202 in the general shape of a "U". In the bottom wall 201 is formed a through opening 204 intended for the passage of the lamp, opening whose dimension is such that the bottom wall 201 forms a shoulder substantially all around it. The wall of background 201 also has localized around from the opening 204 three discrete support pads 2011, 2012 and 2013 for three reference bosses planned on the collar of a standard lamp such as a lamp type "H1", "H4" or "H7".

    Ces trois plots d'appui s'étendent dans un plan commun qui est aussi rigoureusement que possible à l'axe optique x-x du miroir, et grâce au fait qu'ils occupent chacun une surface limitée, il reste possible de démouler le miroir malgré l'absence d'angle de dépouille au niveau des surfaces de ces plots. Comme on l'observe en particulier sur la figure 4, les plots d'appui 2011 et 2012 sont situés au niveau de la partie incurvée de la paroi en U 202, tandis que le troisième plot d'appui 2013 est situé au niveau de la partie de la paroi de fond 201 adjacente au fond 21 du miroir. Les positions angulaires de ces plots par rapport au centre de l'ouverture de lampe 204 sont choisies en fonction du type de lampe, pour correspondre avec des bossages de référence ou analogues prévus sur la collerette de la lampe.These three support pads extend in a plane common which is as rigorously as possible to the axis optical x-x of the mirror, and thanks to the fact that they occupy each a limited surface, it remains possible to unmold the mirror despite the absence of a draft angle at the level surfaces of these studs. As we observe in particularly in Figure 4, the support pads 2011 and 2012 are located at the level of the curved part of the U-shaped wall 202, while the third support pad 2013 is located at the level of the part of the bottom wall 201 adjacent to the bottom 21 of the mirror. Angular positions of these studs relative to the center of the opening of lamp 204 are chosen according to the type of lamp, to match with reference bosses or analogues provided on the flange of the lamp.

    Dans la région de fond de la paroi en U 202 est formé un évidemment 2021 destiné à recevoir, comme le montre en particulier la figure 3, une patte de fixation 151 d'un occulteur 15 destiné à se placer devant la lampe pour éviter l'émission de lumière directe, la patte 151 étant fixée à l'aide d'une vis ou goupille 16 engagée dans un trou 2027 formé au fond de l'évidement 2021 lors du moulage.In the bottom region of the U-shaped wall 202 is formed an obviously 2021 intended to receive, as the shows in particular Figure 3, a mounting lug 151 of a concealer 15 intended to be placed in front of the lamp to avoid the emission of direct light, the tab 151 being fixed with a screw or pin 16 engaged in a hole 2027 formed at the bottom of the recess 2021 when molding.

    Au bord de l'ouverture 204 est également formée une protubérance destinée au détrompage de la lampe (ici une lampe de type « H7 ») pour qu'elle occupe la position angulaire convenue.At the edge of the opening 204 is also formed a protuberance intended for the coding of the lamp (here a lamp "H7" type) so that it occupies the angular position agreed.

    Comme on l'observe en particulier sur les figures 2, 3 et 5, la patte 151 de l'occulteur comporte à son extrémité extérieure une partie 152 recourbée à 180° pour former conjointement avec la face externe de la joue 22 un palier de retenue d'une épingle 300 de verrouillage de la lampe.As seen in particular in Figures 2, 3 and 5, the concealer tab 151 has at its outer end a part 152 bent at 180 ° for form together with the outer face of the cheek 22 a bearing for retaining a pin 300 for locking the lamp.

    Cette épingle, réalisée de façon traditionnelle par pliage d'un ressort-fil, comprend deux branches partant des deux extrémités d'une section d'attache 305 logée dans le palier précité, chacune ce ces deux branches possédant une section de manoeuvre et de verrouillage 301 essentiellement rectiligne et se terminant à l'extrémité libre de la branche par une section terminale 302 recourbée à 180°. Entre la section 301 et la section d'attache 305 est prévue dans chaque branche une section d'appui se composant de deux sous-sections 303, 304 définissant ensemble un « V » dont le sommet est destiné à venir s'appuyer contre l'extérieur de la collerette 13 de la lampe pour assurer son verrouillage en position.This pin, made in a traditional way by folding of a wire spring, includes two branches extending from both ends of a lashing section 305 housed in the aforementioned bearing, each this these two branches having an operating and locking section 301 essentially straight and ending at the end free from branch by terminal section 302 curved at 180 °. Between section 301 and section attachment 305 is provided in each branch a section support consisting of two subsections 303, 304 together defining a "V" whose vertex is intended to come to rest against the outside of the collar 13 to secure it in position.

    Dans les régions d'extrémité libre de la paroi en « U » 202, adjacentes à la partie de fond 21 du miroir, sont formées respectivement deux encoches 2025, venues de moulage (voir figure 5), dans lesquelles les sections 301 des branches de l'épingle 300 peuvent venir s'engager par expansion élastique pour assurer le verrouillage. Des rampes 2023, 2024 en biseau sont formées au niveau de ces encoches, au niveau de l'arête séparant la paroi en « U » 202 de la joue 22 du miroir, pour faciliter l'engagement desdites sections 301 lors du verrouillage. In the free end regions of the wall in “U” 202, adjacent to the bottom part 21 of the mirror, two notches 2025 are formed respectively, coming from molding (see Figure 5), in which sections 301 branches of the pin 300 can be engaged by elastic expansion to ensure locking. Of 2023, 2024 bevelled ramps are formed at these notches, at the edge separating the U-shaped wall 202 of the cheek 22 of the mirror, to facilitate engagement of said sections 301 during locking.

    Le déverrouillage de l'épingle 300 s'effectue simplement en rapprochant manuellement l'une de l'autre les extrémités de ses deux branches, pour dégager les sections 301 de leurs encoches respectives 2025.Pin 300 is unlocked simply by manually moving one towards the other the ends of its two branches, to release the sections 301 of their respective notches 2025.

    On réalise ainsi, sans pièce additionnelle et directement par des aménagements venus de moulage lors de la fabrication du miroir, et donc de façon simple et économique, un porte-lampe assurant un positionnement et un maintien tout à fait satisfaisants de la lampe, et ce en dépit des angles de dépouille nécessaires au démoulage.We thus realize, without additional part and directly by fittings from molding during the manufacture of the mirror, and therefore in a simple and economical, a lamp holder ensuring positioning and completely satisfactory maintenance of the lamp, and this despite the clearance angles necessary for demoulding.

    Les figures 6 à 8 illustrent une variante de réalisation de l'invention permettant d'améliorer la précision du positionnement de la lampe 10 transversalement à son axe.Figures 6 to 8 illustrate a variant of realization of the invention making it possible to improve the lamp positioning accuracy 10 transversely to its axis.

    Selon cette variante, la patte 151 de fixation de l'occulteur possède en outre, par rapport à la forme de réalisation précédente, une languette élastique 153 réalisée par découpage et déformation permanente, le découpage de cette languette étant par exemple fait dans la continuité du contour de l'orifice 154 destiné à la vis ou goupille de fixation 16, entre cet orifice et l'occulteur 15 suivant la direction longitudinale de la patte 151.According to this variant, the tab 151 for fixing the concealer also has, with respect to the form of previous embodiment, an elastic tongue 153 produced by cutting and permanent deformation, the cutting of this tongue being for example made in the continuity of the outline of the orifice 154 intended for the fixing screw or pin 16, between this hole and the concealer 15 in the longitudinal direction of the tab 151.

    La languette 153 est déformée vers l'intérieur de manière à s'appliquer élastiquement contre le bord de la collerette 13 de la lampe à cet endroit. Dans le même temps, l'ouverture 204 pour la lampe est conformée, dans sa région diamétralement opposée à la patte 151 de l'occulteur, de manière à présenter deux faces d'appui radial en « V », respectivement 2015 et 2016, définies par la paroi 201 entourant l'ouverture. Tongue 153 is deformed inward so as to apply elastically against the edge of the flange 13 of the lamp at this location. In the same time, the opening 204 for the lamp is conformed, in its region diametrically opposite to the leg 151 of the screen, so as to present two bearing faces radial in “V”, respectively 2015 and 2016, defined by the wall 201 surrounding the opening.

    De la sorte, la languette 153, en sollicitant la collerette 13 vers ces faces d'appui (selon la flèche F sur la figure 8), réalise un référencement de la position de la collerette 13 de la lampe dans la direction transversale à l'axe de la lampe. Il suffit donc dans ce cas, pour assurer le positionnement de la lampe avec la précision requise, de soigner particulièrement lors de la conception du moule du réflecteur la position de ces surfaces par rapport à la surface de fond du miroir.In this way, the tongue 153, by urging the collar 13 towards these bearing faces (according to the arrow F in FIG. 8), performs a referencing of the position of the flange 13 of the lamp in the direction transverse to the axis of the lamp. It is enough so in this case to ensure the positioning of the lamp with the required precision, to care particularly when designing the mold for the reflector the position of these surfaces relative to the bottom surface of the mirror.

    Maintenant en référence aux figures 9 et 10, on a représenté une seconde forme de réalisation de l'invention.Now with reference to FIGS. 9 and 10, we have shown a second embodiment of the invention.

    Selon celle-ci, la fixation de la lampe est réalisée non plus par une épingle de verrouillage, mais par un mécanisme à baïonette.According to this, the fixing of the lamp is carried out no longer by a locking pin, but by a bayonet mechanism.

    Plus précisément, la région du miroir destinée au montage de la lampe est semblable à celle décrite en référence aux figures précédentes, à ceci près que l'ouverture 204 pour la lampe est bordée par la paroi 201 qui forme un épaulement 201 entièrement lisse et plan, incliné suivant l'axe de dépouille (typiquement de 7°) nécessaire au démoulage. La paroi 201 est donc dépourvue ici des plots d'appui de la forme de réalisation précédentes.More specifically, the region of the mirror intended for fitting of the lamp is similar to that described in reference to the previous figures, except that the opening 204 for the lamp is bordered by the wall 201 which forms a completely smooth and flat shoulder 201, inclined along the draft axis (typically 7 °) necessary for demolding. The wall 201 is therefore devoid of here support pads of the embodiment previous.

    Le porte-lampe comporte dans ce cas un élément métallique généralement cylindrique, illustré sur les figures 9 et 10, globalement désigné par la référence 500.The lamp holder in this case comprises an element generally cylindrical metallic, illustrated on Figures 9 and 10, generally designated by the reference 500.

    Cet élément, à l'état développé (figure 9), comprend un bord supérieur rectiligne 501 et un bord inférieur 501' de forme sinueuse destiné, après mise en forme de l'élément selon une génératrice circulaire, à former un cercle contenu dans un plan incliné à 7° par rapport au plan contenant le cercle formé lors de cette même mise en forme par le bord supérieur 501.This element, in the developed state (Figure 9), includes a straight upper edge 501 and a lower edge 501 'of sinuous shape intended, after shaping the element according to a circular generator, to form a circle contained in a plane inclined at 7 ° relative to the plane containing the circle formed during this same setting formed by the upper edge 501.

    L'élément 500 comporte par ailleurs trois pattes d'appui 502, 503 et 504 destinées à être repliées vers l'extérieur à 90° de manière à former trois plots d'appui pour la lampe, ainsi que trois encoches 505 en forme générale de « L », typiques d'un montage de type baïonette.Element 500 also has three legs support 502, 503 and 504 intended to be folded towards outside at 90 ° so as to form three support pads for the lamp, as well as three 505 shaped notches general of "L", typical of a type mounting bayonet.

    Par ailleurs, la mise en forme de l'élément 500 implique également le pliage à environ 90° suivant des lignes qui séparent une zone 512 et deux zones de bordure 510, 511, de manière à former dans l'élément mis en forme une partie en saillie vers l'extérieur, destinée à se loger étroitement dans un renfoncement du type du renfoncement 2021 décrit plus haut, ceci afin d'assurer, lors du montage de l'élément sur le réflecteur, l'indexation de sa position angulaire.Furthermore, the shaping of the element 500 also involves bending at about 90 ° following lines that separate a 512 area and two border areas 510, 511, so as to form in the shaped element a part projecting outwards, intended to be stay tightly in a recess of the type recess 2021 described above, this in order to ensure, when mounting the element on the reflector, indexing its angular position.

    On comprend que, lorsque le bord 501' de l'élément mis en volume vient s'appuyer contre la paroi 201 orientée suivant l'angle de dépouille, alors le bord supérieur 501 de l'élément forme un cercle qui s'étend dans un plan perpendiculaire à l'axe de l'élément 500, lui-même perpendiculaire à l'axe optique du miroir. La lampe, en s'appuyant sur les trois pattes d'appui 502, 503 et 504 disposées dans ce même plan, va donc adopter dans le miroir l'orientation correcte.It is understood that, when the edge 501 ′ of the element put in volume comes to rest against the wall 201 oriented along the draft angle, then the edge top 501 of the element forms a circle which extends in a plane perpendicular to the axis of the element 500, itself perpendicular to the optical axis of the mirror. The lamp, based on the three support legs 502, 503 and 504 arranged in this same plane, will therefore adopt in the mirror the correct orientation.

    On notera ici que la mise en forme de l'élément 500 s'effectue par roulage de la feuille métallique plane illustrée sur la figure 9, la mise en concordance des extrémités libres de cette feuille au niveau de leur réunion étant assurée ici par des doigts 506 et des encoches 507 mutuellement imbriqués. On observera pour terminer que l'orifice 509 est destiné à être traversé par une vis ou goupille de fixation 16 engagée dans un trou tel que le trou 2027 décrit plus haut, et que de façon diamétralement opposée à cet orifice 509 se trouve un orifice plus grand 508 destiné au passage d'un tournevis pour la vis 16.It will be noted here that the shaping of the element 500 is carried out by rolling the flat metal sheet illustrated in Figure 9, the matching of free ends of this sheet at their meeting being ensured here by fingers 506 and mutually nested 507 notches. We will observe for finish that port 509 is intended to be crossed by a fixing screw or pin 16 engaged in a hole such as hole 2027 described above, and that diametrically opposite to this orifice 509 is a larger orifice 508 intended for the passage of a screwdriver for screw 16.

    On observera également que le dégagement laissé par les zones 510, 511 et 512 de l'élément 500 peut être mis à profit pour recevoir la patte 151 de fixation de l'occulteur 15, comme le montre la figure 10.It will also be observed that the clearance left by fields 510, 511 and 512 of element 500 can be set to take advantage of receiving the mounting tab 151 the concealer 15, as shown in FIG. 10.

    La figure 11 illustre une variante de cette forme de réalisation, suivant laquelle le cercle inférieur de l'élément 500, tel que défini par son bord 501', peut s'appuyer non pas sur la paroi plane 201 inclinée suivant l'angle de dépouille, mais sur un certain nombre de plots, dont en particulier deux plots 2017 et 2018. Ces plots peuvent se trouver, comme pour les plots 2011 à 2013 de la première forme de réalisation, dans un plan parallèle à l'axe optique du miroir, auquel cas l'élément 500 est modifié pour adopter la forme d'un cylindre de hauteur quelconque.Figure 11 illustrates a variant of this form of realization, according to which the lower circle of element 500, as defined by its edge 501 ', can not rest on the flat wall 201 inclined according to the draft angle, but over a number of studs, including in particular two studs 2017 and 2018. These plots can be found, as for the 2011 plots at 2013 of the first embodiment, in a plan parallel to the optical axis of the mirror, in which case the element 500 is modified to adopt the shape of a cylinder of any height.

    Tout autre agencement de tels plots est naturellement possible, auquel cas la forme du bord inférieur 501' de l'élément 500 est adaptée au cas par cas.Any other arrangement of such studs is naturally possible, in which case the shape of the edge lower 501 'of element 500 is adapted to the case by case.

    La figure 12 illustre une autre variante de réalisation, qui concerne l'élément 500. Celui-ci possède les mêmes aménagements que ceux de la figure 9, désignés par les mêmes signes de référence, mais la réunion des deux extrémités de l'élément lors de sa mise en forme cylindrique s'effectue non pas au niveau de l'ouverture 508 pour l'outil de vissage, mais au niveau de la paroi 512 du renfoncement. Dans ce cas, la vis 16 participe utilement au maintien de l'élément 500 en position fermée sur lui-même.Figure 12 illustrates another variant of realization, which concerns element 500. This one has the same arrangements as those in FIG. 9, designated by the same reference signs, but the meeting of two ends of the element during its shaping cylindrical not at the opening 508 for the screwing tool, but at the level of the wall 512 of the recess. In this case, the screw 16 participates usefully for keeping the element 500 in the closed position on himself.

    Bien entendu, la présente invention n'est nullement limitée aux formes de réalisation décrites et représentées, mais l'homme du métier saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is by no means limited to the embodiments described and represented, but the skilled person will be able to bring it any variant or modification in accordance with its spirit.
