Description

DISPOSITIF ANTI-SIPHONNAGEANTI-SIPHONING DEVICE
La présente invention a pour objet un dispositif destiné à être adapté sur l'entrée d'un réservoir de carburant d'un véhicule automobile, notamment un camion, en vue d'empêcher le vol dudit carburant par siphonnage.The present invention relates to a device intended to be adapted to the inlet of a fuel tank of a motor vehicle, including a truck, to prevent theft of said fuel siphoning.
Le vol de carburant par siphonnage des réservoirs des véhicules automobiles, notamment les camions, est relativement fréquent. II est en effet aisé d'enlever le bouchon qui ferme le réservoir pour y introduire un tuyau souple et en siphonner le contenu.Siphon fuel theft from motor vehicle tanks, including trucks, is relatively common. It is indeed easy to remove the cap which closes the tank to introduce a hose and siphon the contents.
Pour pallier cet inconvénient il a été proposé des dispositifs anti-siphonnage pour réservoir de carburant, qui se présentent sous la forme d'un manchon destiné à être introduit dans le tube de remplissage du réservoir et solidarisé au niveau de l'ouverture de celui-ci, et dont le fond est fermé tandis que la paroi est ajourée.To overcome this drawback, it has been proposed anti-siphoning devices for fuel tank, which are in the form of a sleeve intended to be introduced into the tank filling tube and secured to the opening of the latter. ci, and whose bottom is closed while the wall is openwork.
De tels dispositifs sont par exemple décrits dans les documents US 1 931 335 et notamment FR 2 855 463 au Nom du présent demandeur .Such devices are for example described in documents US 1,931,335 and in particular FR 2 855 463 in the name of the present applicant.
Ainsi, le dispositif objet du document FR 2 855 463 comprend un manchon ajouré dont le fond est fermé, et qui est destiné à être introduit dans l'ouverture d'un réservoir de carburant d'un véhicule, ladite ouverture étant du type comprenant une embouchure apte à recevoir un bouchon et qui comprend à cet effet sur son bord extrême une collerette intérieure dans laquelle est pratiqué au moins un évidement destiné à autoriser le passage d'un élément de coincement que comporte ledit bouchon, en sorte de pouvoir, par la rotation axiale dudit bouchon, s'insérer sous ladite collerette et coopérer avec une rampe inclinée pour réaliser un serrage et l'écrasement d'un joint d'étanchéité, jusqu'à venir se bloquer contre une butée, tandis que ledit manchon comporte à son extrémité opposée à celle comportant ledit fond, un adaptateur comprenant deux parties dans le prolongement l'une de l'autre et séparées par une paroi annulaire solidaire dudit manchon, à savoir une première partie en extrémité, comprenant les caractéristiques de ladite embouchure pour recevoir ledit bouchon, c'est-à-dire une collerette comportant au moins un évidement et inférieurement au moins une rampe inclinée aboutissant à une butée, et, sous ladite première partie, une seconde partie prévue apte à coiffer ladite embouchure et qui comporte au moins un élément de coincement faisant saillie du manchon vers l'extérieur et apte à passer dans le ou les évidements de la collerette, et à s'insérer sous cette dernière pour venir se bloquer contre la butée, ainsi que des moyens verrouillage consistant en au moins un élément prédécoupé dans la paroi du manchon, en un emplacement décalé angulairement par rapport audit élément de coincement, et qui est apte, après engagement dudit élément de coincement sous la collerette et blocage de celle-ci contre ladite butée, à être plié vers l'extérieur, en passant par l'ouverture de l'adaptateur, afin de prendre place de l'autre côté de ladite butée.Thus, the device of the document FR 2 855 463 comprises a perforated sleeve whose bottom is closed, and which is intended to be introduced into the opening of a fuel tank of a vehicle, said opening being of the type comprising a mouthpiece adapted to receive a cap and which comprises for this purpose on its extreme edge an inner collar in which is formed at least one recess for allowing the passage of a wedging element that includes said plug, so as to be able, by the axial rotation of said plug, fit under said flange and cooperate with an inclined ramp to perform a clamping and crushing of a seal, until it comes to lock against a stop, while said sleeve comprises at its opposite end to that comprising said bottom, an adapter comprising two parts in the extension of one another and separated by an annular wall integral with said sleeve, namely a first end portion, comprising the characteristics of said mouth for receiving said plug, c that is to say a flange comprising at least one recess and inferiorly at least one inclined ramp ending in an abutment, and, beneath said first part, a second part designed to cap said mouthpiece and which comprises at least one wedging element protruding from the sleeve outwards and able to pass into the recess or recesses of the collar, and to fit under the latter to come to lock against the stop, and locking means consisting of at least one pre-cut element in the wall of the sleeve, at a location angularly offset relative to said wedging element, and which is capable, after engagement of the said wedging element under the flange and locking it against said stop, to be bent outward, through the opening of the adapter, to take place on the other side of said stop.
Un tel dispositif fonctionne parfaitement, le fond qui ferme l'extrémité du manchon interdit l'introduction d'un tuyau de siphonnage, tandis que les ajours autorisent le remplissage du réservoir .Such a device works perfectly, the bottom that closes the end of the sleeve prohibits the introduction of a siphoning pipe, while openings allow the filling of the tank.
Ce dispositif présente cependant des inconvénients. En effet, l'élément de coincement se présente sous la forme d'une patte radiale s' étendant dans un plan perpendiculaire à l'axe principal du manchon, et qui est obtenue par pliage d'un élément découpé dans ledit manchon. Or, il a été constaté qu'en exerçant une forte traction sur le manchon, la patte en étant forcée contre la collerette, se replie, libérant ainsi le manchon.This device however has disadvantages. Indeed, the wedging element is in the form of a radial tab extending in a plane perpendicular to the main axis of the sleeve, and which is obtained by folding a cut element in said sleeve. However, it has been found that by exerting a strong traction on the sleeve, the tab being forced against the flange, folds, thus releasing the sleeve.
Par ailleurs, les moyens verrouillage qui consistent en au moins un élément prédécoupé dans la paroi du manchon sont de même construction que le ou les éléments de coincement, en sortent qu'ils subissent le même sort.Moreover, the locking means which consist of at least one pre-cut element in the wall of the sleeve are likewise construction that the element or elements of jamming, come out that they undergo the same fate.
La présente invention a pour but de proposer un dispositif anti- siphonnage permettant de remédier aux divers inconvénients précités .The present invention aims to provide an anti-siphoning device to overcome the various aforementioned drawbacks.

En référence à la figure 1, on peut voir l'embouchure 1 d'un réservoir de carburant d'un véhicule et un dispositif anti- siphonnage selon l'invention. De manière connue, cette embouchure 1 présente une forme annulaire, et son bord extrême est garni d'une collerette intérieure 10 dans laquelle sont pratiqués deux évidements 11, et qui comporte inférieurement, entre chacun des évidements 11, une rampe inclinée 12 aboutissant à une butée 13. En pratique, cette embouchure 1 est destinée à recevoir un bouchon, non représenté, comprenant deux pattes s'étendant radialement, dans un plan perpendiculaire à 1' axe de l' embouchure 1 , en vue d' une fixation de type à baïonnette, c'est-à-dire en étant introduites dans les évidements 11 , pour être coincées sous la collerette 10 et venir en blocage contre les butées 13.With reference to FIG. 1, one can see the mouth 1 of a fuel tank of a vehicle and an anti-siphoning device according to the invention. In known manner, this mouth 1 has an annular shape, and its extreme edge is lined with an inner flange 10 in which are formed two recesses 11, and which comprises below, between each of the recesses 11, an inclined ramp 12 leading to a 13. In practice, this mouth 1 is intended to receive a stopper, not shown, comprising two radially extending tabs, in a plane perpendicular to the axis of the mouth 1, in view of a type of attachment. bayonet, that is to say being introduced into the recesses 11, to be wedged under the flange 10 and come into block against the stops 13.
Le dispositif anti-siphonnage 2 selon l'invention comporte de manière connue un manchon 20 dont la paroi tubulaire 21 est percée d'orifices 22, et dont l'extrémité inférieure est fermée d'un fond 23.The anti-siphoning device 2 according to the invention comprises, in known manner, a sleeve 20 whose tubular wall 21 is pierced with orifices 22, and whose bottom end is closed by a bottom 23.
L'extrémité supérieure, opposée à celle comportant le fond 23, est munie d'un adaptateur 3 comprenant une partie supérieure 4 et une partie inférieure 5.The upper end, opposite to that comprising the bottom 23, is provided with an adapter 3 comprising an upper part 4 and a lower part 5.
La partie supérieure 4 est destinée à recevoir le bouchon d'origine, non représenté, et elle présente à cet effet les mêmes caractéristiques que l'embouchure 1, c'est-à-dire une forme annulaire, un bord extrême garni intérieurement d'une collerette 40 dans laquelle sont découpés deux évidements 41, et comprenant inférieurement, entre chaque évidement 41, une rampe inclinée 42 aboutissant à une butée 43. La partie inférieure 5, comme cela est plus particulièrement visible sur la figure 2 , se présente sous la forme d' une coiffe annulaire, délimitée extérieurement par une paroi tubulaire 50, intérieurement par la paroi tubulaire 21 du manchon 20, et supérieurement par une paroi annulaire séparant les parties 44 et 5.The upper part 4 is intended to receive the original cap, not shown, and it has for this purpose the same characteristics as the mouth 1, that is to say, an annular shape, an extreme edge lined internally with a flange 40 in which are cut two recesses 41, and comprising below, between each recess 41, an inclined ramp 42 leading to a stop 43. The lower part 5, as is more particularly visible in FIG. 2, is in the form of an annular cap, delimited externally by a tubular wall 50, internally by the tubular wall 21 of the sleeve 20, and superiorly by a wall ring separating portions 44 and 5.
Cette partie inférieure 5 est destinée à loger l'embouchure 1 et à permettre la fixation à cette dernière du dispositif anti- siphonnage 2. A cet effet, elle présente les caractéristiques structurelles du bouchon, c'est-à-dire que de la paroi tubulaire 21 font saillie diamétralement des éléments de coincement 6, dont un seul est visible sur la figure, destinés à passer dans les évidements 11 et à se bloquer sous la collerette 10 contre les butées 13.This lower part 5 is intended to house the mouth 1 and to allow attachment to the latter of the anti-siphoning device 2. For this purpose, it has the structural characteristics of the plug, that is to say that the wall tubular 21 protrude diametrically wedging elements 6, only one of which is visible in the figure, intended to pass into the recesses 11 and to lock under the flange 10 against the abutments 13.
Selon l'invention, chaque élément de coincement 6 se présente sous la forme d'une paire 60 d'éléments 61 chacun consistant en une lame venant d'une découpe 24 de la paroi 21 selon un trait en forme de U, et pliée selon un pli 62 coïncidant avec une génératrice du manchon 20, en sorte de s'étendre selon un plan radial à ce dernier.According to the invention, each wedging element 6 is in the form of a pair 60 of elements 61 each consisting of a blade coming from a cutout 24 of the wall 21 in a U-shaped line, and folded according to a fold 62 coinciding with a generatrix of the sleeve 20, so as to extend in a radial plane to the latter.
Les deux éléments 61 d'une paire 60 sont décalés angulairement, et éloignés l'un de l'autre d'une distance inférieure à celle de l'évidement 41, en sorte de pouvoir être introduite dans celui- ci .The two elements 61 of a pair 60 are angularly offset, and spaced from each other by a distance less than that of the recess 41, so as to be introduced therein.
On notera que de manière avantageuse chacun des éléments 61 comporte au niveau du pli 62 , un embouti de raidissement 63 permettant de garantir la position écartée de l'élément 61.Note that advantageously each element 61 comprises at the fold 62, a stiffening stamping 63 to ensure the spaced position of the element 61.
On notera également que chaque paire 60 d'éléments 61 peut être remplacée par un seul élément 61. Par ailleurs, le manchon 20 comporte à proximité de chacune des paires 60 d'éléments, dont une seule est visible, décalée angulairement, une découpe 25 selon un trait en forme de U, qui délimite une lame 26 susceptible d'être pliée vers l'extérieur.It will also be noted that each pair 60 of elements 61 can be replaced by a single element 61. Moreover, the sleeve 20 comprises near each of the pairs 60 of elements, only one of which is visible, angularly offset, a cutout 25 in a U-shaped line, which delimits a blade 26 that can be folded towards the outside. 'outside.
Cette lame 26 peut s'étendre, comme cela est visible sur les figures respectivement 2 et 3, selon perpendiculaire à l'axe du manchon 20, ou selon un plan radial à cet axe.This blade 26 may extend, as can be seen in FIGS. 2 and 3 respectively, perpendicular to the axis of the sleeve 20, or in a plane radial to this axis.
Le pliage de la lame 26 est destiné à être réalisé après vissage du dispositif anti-siphonnage 2, depuis l'intérieur du manchon 20, pour venir contre la butée 13, de l'autre côté de celle-ci, en sorte d' enserrer celle-ci et ainsi empêcher la rotation axiale, dans un sens comme dans l'autre du dispositif anti- siphonnage.The folding of the blade 26 is intended to be performed after screwing the anti-siphoning device 2, from the inside of the sleeve 20, to come against the abutment 13, on the other side thereof, so as to grip this and thus prevent the axial rotation, in either direction of the anti-siphon device.
Du fait du pliage des lames 26 depuis l'intérieur vers l'extérieur, il n'est pas possible d'accéder à celles-ci pour les plier frauduleusement dans le sens inverse.Due to the folding of the blades 26 from the inside to the outside, it is not possible to access them to bend them fraudulently in the opposite direction.
De préférence, dans le cas de la figure 2, la lame 26 est destinée à être pliée en direction de la paroi annulaire 44 , jusqu'à éventuellement venir au contact de celle-ci. La lame 26 pourrait également être prévue pliable de l'autre côté avec pour inconvénient le risque d'un repliement, frauduleux, à plat le long de la paroi 21 , supprimant ainsi le verrouillage . Preferably, in the case of Figure 2, the blade 26 is intended to be folded towards the annular wall 44, until possibly come into contact therewith. The blade 26 could also be provided foldable on the other side with the disadvantage of the risk of a folding, fraudulent, flat along the wall 21, thus removing the lock.
