Description

La présente invention a pour objet un dispositif destiné àThe subject of the present invention is a device intended for

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.  be adapted to the inlet of a fuel tank of a motor vehicle, in particular a truck, in order to prevent theft of said fuel by siphoning.

Le vol de carburant par siphonnage des réservoirs des véhicules automobiles, notamment les camions, est relativement fréquent. Il est en effet aisé d'enlever le bouchon qui ferme le réservoir pour y introduire un tuyau souple et en siphonner le contenu.  Theft of fuel by siphoning tanks from motor vehicles, especially trucks, is relatively frequent. It is indeed easy to remove the cap which closes the tank to introduce a flexible hose and siphon the contents.

Pour pallier cet inconvénient il est possible d'utiliser des bouchons qui ferment à clef, ce qui cependant demeure contraignant pour l'utilisateur, de plus cela n'arrête pas les voleurs qui arrivent généralement à casser la serrure.  To overcome this drawback it is possible to use plugs which lock with a key, which however remains restrictive for the user, moreover it does not stop thieves who generally manage to break the lock.

On connaît par ailleurs des dispositifs anti-siphonnage 15 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, de tels dispositifs sont par exemple décrits dans les 20 documents US 4.630.748, US 5.476.185, EP 901.926, FR 2.463.694 et FR 2.820.372.  Anti-siphoning devices 15 are also known for fuel tanks, which are in the form of a sleeve intended to be introduced into the filling tube of the tank and secured at the opening of the latter, and whose bottom is closed while the wall is perforated, such devices are for example described in the documents US 4,630,748, US 5,476,185, EP 901,926, FR 2,463,694 and FR 2,820,372.

Ces dispositifs fonctionnent parfaitement, le fond qui ferme l'extrémité du manchon interdit l'introduction d'un tuyau de siphonnage, tandis que les ouvertures de la paroi autorisent 25 le remplissage du réservoir.  These devices work perfectly, the bottom which closes the end of the sleeve prevents the introduction of a siphon pipe, while the openings in the wall allow the tank to be filled.

Ces dispositifs anti-siphonnage présentent toutefois des inconvénients, notamment en ce qui concerne leur mode de solidarisation au réservoir, car ils doivent bien entendu être indémontables. En effet, ils sont fixés soit par soudage, ce qui 30 nécessite des précautions particulières, soit par vissage ou rivetage après avoir réalisé des trous dans le tube de remplissage avec le risque d'introduire de la limaille dans le réservoir, soit par coinçage, au moyen d'éléments ressorts aptes à se déployer vers l'extérieur après introduction, ce qui 35 n'assure pas une fixation sans jeu.  However, these anti-siphoning devices have drawbacks, in particular as regards their method of attachment to the tank, since they must of course be removable. In fact, they are fixed either by welding, which requires special precautions, or by screwing or riveting after making holes in the filling tube with the risk of introducing filings into the tank, or by wedging, by means of spring elements capable of deploying outwards after insertion, which does not ensure a fixation without play.

La présente invention a pour but de proposer un dispositif antisiphonnage permettant de remédier aux divers inconvénients précités.  The object of the present invention is to propose an anti-siphoning device making it possible to remedy the various aforementioned drawbacks.

Le dispositif anti-siphonnage selon l'invention est du type 5 comprenant un manchon dont la paroi est ajourée et le fond 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 10 intérieure dans laquelle sont pratiqués au moins deux évidements destinés à autoriser le passage de pattes radiales que comporte ledit bouchon, en sorte que chacune puisse, par la rotation axiale dudit bouchon, s'insérer sous ladite collerette et coopérer avec une rampe inclinée pour réaliser un serrage pour 15 écraser un joint d'étanchéité, jusqu'à venir se bloquer contre une butée, et il se caractérise essentiellement en ce que ledit manchon comporte à son extrémité opposée à celle comportant ledit fond, un adaptateur comprenant deux parties dans le prolongement l'une l'autre et séparées par une paroi annulaire 20 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 deux évidements et inférieurement des rampes inclinées aboutissant à des butées, et, sous ladite première 25 partie, une seconde partie apte à coiffer ladite embouchure et qui comporte des moyens permettant son serrage sur cette dernière, ainsi que des moyens permettant son verrouillage.  The anti-siphoning device according to the invention is of type 5 comprising a sleeve whose wall is perforated and the bottom 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 capable of receiving a stopper, and which for this purpose comprises on its end edge an inner flange 10 in which are formed at least two recesses intended to allow the passage of radial lugs which said stopper comprises, so that each can, by the axial rotation of said plug, be inserted under said flange and cooperate with an inclined ramp to produce a tightening to crush a seal, until it comes to block against a stop, and it is essentially characterized in that said sleeve comprises at its end opposite to that comprising said bottom, an adapter comprising two parts in the extension of one another and separ arées by an annular wall 20 integral with said sleeve, namely a first end portion, comprising the characteristics of said mouth to receive said plug, that is to say a flange comprising at least two recesses and lower inclined ramps leading to stops, and, under said first part, a second part capable of covering said mouth and which comprises means allowing its clamping on the latter, as well as means allowing its locking.

Selon une caractéristique additionnelle du dispositif selon l'invention, les moyens permettant le serrage sur l'embouchure 30 consistent en des pattes radiales faisant saillies du manchon vers l'extérieur et aptes à passer dans les évidements de la collerette, et à s'insérer sous cette dernière pour venir se bloquer contre les butées.  According to an additional characteristic of the device according to the invention, the means allowing the clamping on the mouth 30 consist of radial lugs protruding from the sleeve towards the outside and able to pass into the recesses of the collar, and to be inserted under the latter to come and lock against the stops.

Selon une autre caractéristique additionnelle du dispositif 35 selon l'invention, les moyens permettant le verrouillage consistent en au moins un élément prédécoupé dans la paroi du manchon, en un emplacement décalé angulairement par rapport à la patte radiale qui lui correspond, et qui est apte, après engagement de ladite patte sous la collerette et blocage de celle-ci contre la butée, à être plié vers l'extérieur, en 5 passant par l'ouverture de l'adaptateur, afin de prendre place de l'autre côté de ladite butée.  According to another additional characteristic of the device 35 according to the invention, the means allowing the locking consist of at least one element precut in the wall of the sleeve, in a location offset angularly relative to the radial tab which corresponds to it, and which is suitable , after engagement of said tab under the collar and locking of the latter against the stop, to be folded outwards, passing through the opening of the adapter, in order to take place on the other side of said stop.

Selon un mode de réalisation préférentiel du dispositif selon l'invention, l'élément prédécoupé est disposé en sorte que, pour prendre sa position de verrouillage, il puisse être 10 plié en direction de la paroi annulaire séparant les deux parties de l'adaptateur, pour pouvoir, éventuellement, venir au contact de celle-ci.  According to a preferred embodiment of the device according to the invention, the precut element is arranged so that, in order to assume its locking position, it can be folded in the direction of the annular wall separating the two parts of the adapter, to be able to possibly come into contact with it.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui 15 suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.  The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé : - la figure 1 représente une vue schématique en perspective d'un dispositif anti-siphonnage selon l'invention lors de sa 20 mise en place.  In the accompanying drawing: - Figure 1 shows a schematic perspective view of an anti-siphoning device according to the invention when it is put in place.

- la figure 2 représente une vue schématique partielle du même dispositif sous un autre angle.  - Figure 2 shows a partial schematic view of the same device from another angle.

En référence à la figure 1, on peut voir l'embouchure 1 d'un réservoir de carburant d'un véhicule et un dispositif anti25 siphonnage selon l'invention. De manière connue, cette embouchure 1 présente une forme annulaire, et 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 30 aboutissant à une butée 13. En pratique, cette embouchure 1 est destinée à recevoir un bouchon, non représenté, comprenant deux pattes s'étendant radialement 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 35 en blocage contre les butées 13.  Referring to Figure 1, we can see the mouth 1 of a vehicle fuel tank and an anti-siphoning device according to the invention. In known manner, this mouthpiece 1 has an annular shape, and the extreme edge is provided with an inner flange 10 in which two recesses 11 are made, and which comprises, between each of the recesses 11, an inclined ramp 12 30 leading to a stop 13. In practice, this mouthpiece 1 is intended to receive a stopper, not shown, comprising two legs extending radially for a bayonet type fixing, that is to say by being inserted into the recesses 11, so as to be wedged under the flange 10 and come to block 35 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 a known manner a sleeve 20 whose tubular wall 21 is pierced with orifices 22, and whose lower end is closed with a bottom 23.

Selon l'invention, 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.  According to the invention, 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 10 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.  The upper part 4 is intended to receive the original plug, 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 internally trimmed. a collar 40 in which two recesses 41 are cut, and comprising, between each recess 41, an inclined ramp 42 leading to a stop 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 20 les parties 44 et 5.  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 parts 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 25 la paroi tubulaire 21 font saillie diamétralement deux pattes 24, dont une seule est visible sur la figure, destinées à passer dans les évidements 11 et à se bloquer sous la collerette 10 contre les butées 13. Chacune des pattes vient du pliage d'une lame issue de la découpe de la paroi 21 selon une ligne en forme 30 de U. Par ailleurs, le manchon 20 comporte à proximité de chacune des pattes 24, dont une seule est visible, décalée angulairement, une découpe 25 selon une ligne en forme de U, qui délimite une lame 26 susceptible d'être pliée vers l'extérieur, 35 comme la patte 24. 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.  This lower part 5 is intended to accommodate the mouth 1 and to allow the attachment to the latter of the anti-siphon device 2. For this purpose, it has the structural characteristics of the plug, that is to say from the tubular wall 21 project diametrically two legs 24, only one of which is visible in the figure, intended to pass into the recesses 11 and to be blocked under the flange 10 against the stops 13. Each of the legs comes from the folding of a blade from of the cutout of the wall 21 along a U-shaped line 30. Furthermore, the sleeve 20 comprises, near each of the tabs 24, only one of which is visible, angularly offset, a cutout 25 along a U-shaped line , which delimits a blade 26 capable of being folded outwards, like the tab 24. The folding of the blade 26 is intended to be carried out after screwing the anti-siphoning device 2, from the inside of the sleeve 20, to come c ontre the stop 13, on the other side thereof, so as to enclose it and thus prevent axial rotation, in one direction as in the other of the anti-siphoning 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 fraudulently fold them in the opposite direction.

De préférence, la patte 26 est destinée à être pliée en direction de la paroi annulaire 44, jusqu'à éventuellement venir 10 au contact de celleci. La patte 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, the tab 26 is intended to be folded in the direction of the annular wall 44, until possibly coming into contact with it. The tab 26 could also be provided foldable on the other side with the drawback of the risk of folding, fraudulently, flat along the wall 21, thus eliminating the locking.

Selon le mode de réalisation représenté, en cas de 15 tentative de repliement de la patte 26, celle-ci bute contre la paroi annulaire 44 et demeure sensiblement horizontale et conserve sa fonction de verrouillage.  According to the embodiment shown, in the event of an attempt to fold the tab 26, the latter abuts against the annular wall 44 and remains substantially horizontal and retains its locking function.

Selon le type de réservoir à équiper, c'est-à-dire selon le constructeur du véhicule, le nombre de pattes 24 peut varier, 20 ainsi que leur emplacement et que l'espace angulaire les séparant des lames 26.  Depending on the type of tank to be fitted, that is to say according to the vehicle manufacturer, the number of legs 24 may vary, as well as their location and the angular space separating them from the blades 26.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède de l'un de ses modes de réalisation, susceptible de subir quelques modifications sans 25 pour autant sortir du cadre de l'invention.  It goes without saying that the present invention cannot be limited to the foregoing description of one of its embodiments, capable of undergoing some modifications without departing from the scope of the invention.
