Means of transport.

Description

La présente invention concerne un dispositif antivol, notamment pour véhicule automobile ou tout engin de trans- port utilisant un carburant liquide. The present invention relates to an anti-theft device, in particular for a motor vehicle or any transport vehicle using liquid fuel.

On connaît de très nombreux dispositifs antivol pour voitures, les plus répandus comprenant des serrures de portière, des dispositifs de blocage du volant de direction et plus récemment des sirènes ou avertisseurs sonores. Cependant tous ces dispositifs présentent un certain nombre d'inconvénients au niveau de leur fiabilité et de leur résistance à l'effraction. Very numerous anti-theft devices for cars are known, the most widespread comprising door locks, steering wheel blocking devices and more recently sirens or audible warning devices. However, all these devices have a certain number of drawbacks in terms of their reliability and their resistance to burglary.

Selon l'invention, on propose un dispositif antivol simple, facile à installer et très efficace. I1 est caractérisé en ce qu'il comprend des moyens pour couper l'arrivée du carburant, intercalés sur le conduit d'alimentation du moteur. Selon une variante préférée, ces moyens comprennent un bloc métallique contenant des o;i- duits de carburant, et un obturateur d'au moins l'un des conduits commandé par une serrure à douille sollicitée par un ressort. According to the invention, a simple anti-theft device is proposed, easy to install and very effective. I1 is characterized in that it comprises means for cutting off the supply of fuel, interposed on the engine supply duct. According to a preferred variant, these means comprise a metal block containing o; i- fuel lines, and a shutter of at least one of the conduits controlled by a socket lock biased by a spring.

Selon d'autres variantes - l'obturateur consiste en une rondelle de matériau tlsss- tique tel que du caoutchouc fixée à une tige, l'ensemble formant soupape - la tige est associée à un ressort qui la sollicite Jans le sens de l'ouverture de la soupape - le dispositif antivol est muni de moyens pour son installation sur le plancher du véhicule. According to other variants - the shutter consists of a washer of flexible material such as rubber fixed to a rod, the valve assembly - the rod is associated with a spring which urges it in the direction of opening of the valve - the anti-theft device is provided with means for its installation on the vehicle floor.

L'invention sera maintenant décrite plus en détail avec référence au dssin annexé sur lequel la Fig. unique représente une vue sur. coupe avec arrachement partiel d'un mcd de réalisation du dispositif antivol, e position feir..  The invention will now be described in more detail with reference to the accompanying drawing in which FIG. unique represents a view on. section with partial cutaway of a mcd for making the anti-theft device, e position feir ..

Je dispositif représenté sur cette Fig. comprend un blo métallique 1 dont la partie supérieure 2, de forme sensiblement cylindrique, est filetée afin de permettre sa fixation à l'aide d'écrous 3 (et le cas échéant par l'intermédiaire de rondelles non représentées) sur le plancher 4 d'un véhicule automobile. Le dispositif est intercalé sur le conduit 5,5' d'alimentation du moteur, par exemple au moyen de raccords 6 à olive 7 et, dans ce cas , le bloc 1 comprend le filetage correspondant à ces raccords. The device shown in this FIG. comprises a metal block 1, the upper part 2 of which is substantially cylindrical in shape, is threaded so as to allow it to be fixed using nuts 3 (and if necessary by means of washers not shown) on the floor 4 d 'a motor vehicle. The device is interposed on the motor supply duct 5.5 ′, for example by means of fittings 6 to olive 7 and, in this case, the block 1 comprises the thread corresponding to these fittings.

Lorsque le dispositif est en position ouverte, le carburant provenant du conduit 5 traverse successivement le conduit 8, la chambre 9, le logement 10 et le conduit 11, avant de quitter le dispositif antivol par le conduit 5'. Une rondelle de caoutchouc 12 permet d'obturer le logement 10, interdisant ainsi au carburant la traversée du dispositif. Cette rondelle de caoutchouc 12 est fixée (par exemple au moyen d'écrous et de rondelles) à une tige 13 qui est commandée par la douille cylindrique 14 d'une serrure. Cette douille 14 est sollicitée (vers la position ouverte) par un ressort 15 s'appuyant sur une pièce filetée 16 vissée à l'intérieur du bloc 1. Par ailleurs, la tige 13 est sollicitée dans le sens de l'ouverture par un ressort 17 provoquant le soulèvement de la rondelle de caoutchouc 12 et par suite la libération de la chambre 9 pour le passage du carburant.L'ensemble rondelle 12, tige 13 et ressort 17 forment une soupape. When the device is in the open position, the fuel coming from the pipe 5 passes successively through the pipe 8, the chamber 9, the housing 10 and the pipe 11, before leaving the anti-theft device via the pipe 5 '. A rubber washer 12 makes it possible to close the housing 10, thus preventing fuel from passing through the device. This rubber washer 12 is fixed (for example by means of nuts and washers) to a rod 13 which is controlled by the cylindrical sleeve 14 of a lock. This socket 14 is urged (towards the open position) by a spring 15 resting on a threaded piece 16 screwed inside the block 1. Furthermore, the rod 13 is urged in the direction of opening by a spring 17 causing the lifting of the rubber washer 12 and consequently the release of the chamber 9 for the passage of the fuel. The washer 12, rod 13 and spring 17 assembly form a valve.

Ainsi, lorsque l'on appuie, par exemple par simple pression du pied, sur la douille 14 (passant de la position ouverte B à la position fermée A) on comprime simultanément les ressorts 15 et 17, la rondelle de caoutchouc 12 étant plaquée contre l'ouverture du logement 10, et l'on provoque en même temps le blocage de l'ensemble au moyen de l'ergot de la serrure venant se loger dans le trou 18 ménagé dans le bloc 1. Pour repasser à la position ouverte B, on ouvre la serrure avec sa clé (non représentée), provoquant le retrait de l'ergot du trou 18 et ainsi le déblocage et la remontée de la douille 14, et par suite celle de la tige 13 et de la rondelle 12. Thus, when one presses, for example by simple pressure of the foot, on the sleeve 14 (passing from the open position B to the closed position A) the springs 15 and 17 are simultaneously compressed, the rubber washer 12 being pressed against the opening of the housing 10, and at the same time the blocking of the assembly is caused by means of the lug of the lock coming to be housed in the hole 18 formed in the block 1. To return to the open position B , the lock is opened with its key (not shown), causing the lug to be withdrawn from the hole 18 and thus the unlocking and the ascent of the sleeve 14, and consequently that of the rod 13 and of the washer 12.

Le dispositif antivol selon l'invention peut être facilement installé sur le plancher d'un véhicule automobile, même de manière pratiquement invisible sous le tapis. I1 peut être utilement équipé d'un carter de protection.  The anti-theft device according to the invention can be easily installed on the floor of a motor vehicle, even practically invisible under the carpet. It can be usefully fitted with a protective casing.
