Description

The present invention relates to the field of road safety and more particularly to the stopping of vehicles on the run, otherwise called fleeing vehicles.

Stopping fleeing vehicles turns out to have become a key area of public and private security.

Indeed, with in particular the increase in commercial and private traffic, and the increase in the porosity of borders, there is an increasing need to benefit from solutions allowing to stop a fleeing vehicle presenting a certain number of benefits.

More particularly since the 1990s, numerous approaches have been taken in this area of stopping fleeing vehicles because it is necessary to have effective means which can neither lead to injuries, nor endanger the driver of the fleeing vehicle, nor endanger the manipulator.

In the prior art, many solutions have been proposed.

The best known products are those of the STOPSTICK® range, which are marketed worldwide.

The STOPSTICK® range is made up of several products: STOPSTICK® puncture modules with triangular section, PATROL TERMINATOR® puncture modules, BARRACUDA® puncture modules, etc.

A certain number of applications and patents corresponding to the STOPSTICK® range can be cited, in particular patents US5330285 , US5820293 and US5542962 , Requirement US2014199118 .

The most frequent use of STOPSTICK® puncture modules with triangular section is the simple throw in front of a fleeing vehicle. The manipulator directly has a STOPSTICK® puncture module with triangular section (or two nested) in the hand and launches them in front of the fleeing vehicle when the latter passes. He therefore has the obligation to be close to the vehicle, and is therefore in danger during handling.

An alternative technique for positioning a STOPSTICK® puncture module (s) with a triangular section consists in launching the puncture module (s) from a side of the road opposite to that which is about to run alongside the fleeing vehicle and pull the puncture module (s) by means of a wire (by reel or not) in order to place it / them in the vicinity of the tires of the fleeing vehicle when the latter passes. Again, the manipulator can be exposed to a danger because it is necessarily close to the fleeing vehicle.

If the STOPSTICK® puncture modules with triangular section are considered as the reference puncture modules, the positioning of these is not without risk, of misfire, because it is difficult for the manipulator to launch correctly the module (s) and / or bring them back to him at the precise moment when the fleeing vehicle passes.

Other products in the range can be mentioned, in particular the PATROL TERMINATOR® puncture modules intended to stop light vehicles, or even the BARRACUDA® puncture modules intended to stop trucks, buses, etc. Thus, depending on the use, different puncture modules must be used depending in particular on the type of vehicle to be stopped.

These products have the same drawbacks as the STOPSTICK® puncture modules with triangular section, they must be put in place by a manipulator being close to the vehicle to be stopped.

Given the presence of the manipulator and the manipulation that will be seen by the driver of the fleeing vehicle, the latter is likely to turn away from its trajectory and crash into the manipulator. This is all the more annoying as the handling agent will have difficulty reacting when he is occupied with the positioning of the modules.

In addition, the deployment time is relatively long, insofar as it requires a throw, then a draw. In addition, throwing must be taught to the manipulators.

Finally, the use of a wire during the drawing is not without risks insofar as the fleeing vehicle can take away the module (s). Finally, after the passage of the front wheel, the STOPSTICK® moves randomly.

A certain number of patent applications or patents relate to fixed systems, that is to say intended to be fixed on the road, or even to be incorporated therein. This is particularly the case of the system presented in the application US2011229260 in the name of Scott, in which a slide is fixed to the ground.

Fixed systems obviously have the disadvantage of not being transportable, difficult to replace, etc. but are justified for example at border posts and highway tolls.

Regarding transportable harrows, probably due to the danger of launching / pulling STOPSTICK® puncture modules with triangular section, some teams have worked on relatively complex deployment systems, like the system described in the request. FR2714404 in the name of Lang, in which the portable harrow has an element designed to unroll, unfold, raise or push it.

In the request US2012243935 , a complex system of multiple hinges for stretching the harrow is also described.

Other teams have worked on alternative or complementary tire puncture systems to stop a leaking vehicle. This is particularly the case for the inventors of the patent US8186905 in the name of Castro, who discloses a fleeing vehicle stop system independent of the configuration of the wheels or the chassis.

The system described in particular includes mechanisms for deploying membranes / tips. The membranes, for example nets, are attached to the tips. When the points are lodged in the tire during the passage of the vehicle, the membranes, for example nets, are wound around the wheel and thus immobilize the fleeing vehicle.

A similar system is presented in the application WO2005093163 on behalf of ISRAEL AIRCRAFT INDUSTRIES LTD.

Requirement WO2010026202 in the name of IFTACH SEGAL relates to a system made up of a substrate accommodating a certain number of points. When the vehicle tire is punctured, the substrate, fixed by means of the spikes, comes to wrap around the wheel and forces the vehicle to stop. In the Figure 6 , an embodiment is presented in which certain points are completely included in said substrate.

Such systems are unsatisfactory, in particular because the reloading is very long or impossible (need to quickly have a net which must be folded in a certain way, etc.) and they do not allow positioning very prior to the passage of the vehicle.

In the request FR2760026 in the name of France, a puncture device is presented consisting of a textile band presented as rigid, on this band is glued a strip of velcro, itself receiving spikes, the spikes being fixed by the velcro by the through a metal washer attached to the tip.

This device has a certain number of drawbacks, in particular the textile strip is liable to be carried away, the tip is liable to tip over and "lie down" when the vehicle passes and therefore not puncture the tire, being given the weak base provided by the washer. In addition, this device has a single rupture zone, due to the velcro.

Other teams have worked on points that stand out with other elements. In the request WO2008071954 on behalf of Mac Clean, a puncture system comprising a number of arms is presented. In the Figure 4 , he is presented spikes mounted on such elements, which are themselves mounted on the arms.

During the passage of the vehicle, the tip and the element are released from the arm.

This solution has a certain number of disadvantages, insofar as the element can notably considerably reduce the handling of the fleeing vehicle once the latter is secured to the tire via the tip. Indeed, in the present invention, the preservation of the safety of the driver of the fleeing vehicle, even if it was at fault, remains a key element.

In addition, in this application, the point is oriented approximately 45 ° relative to the surface on which the vehicle is traveling, this is in particular illustrated by the Figure 4 . This is a solution to the problem mentioned above of the "coating" of the tip.

In the patent US 3,456,920 in the name of Elvington, there is described a system composed of a non-rigid strip of fabric or film, on which are positioned several points comprising a washer base. The base of the tip is removably glued to the non-rigid strip. The tape must be wound manually after each use, it cannot therefore be used several times in a short time (as for example in the case of several fleeing vehicles following each other).

In the patent US 6,551,013 in the name of Blair, there is described a system composed of a non-rigid metal plate, the plate comprises adhesion strips fixed to said plate. The adhesion strips are removably linked to base spikes.

In the patent US 5,482,397 in the name of Soleau, there is described a system comprising a plate, on which are removably linked several base points. This system does not have puncture organs detachable from the puncture module, nor means for grouping the puncture organs being a carrier plate.

In these last three US patents, there is a single removable connection in the system, between the tip and the support (strip or plate). This link is intended to be broken each time the tip enters the tire.

Some teams have worked on systems that can be positioned before the vehicle arrives.

For example in the request US2012237293 on behalf of PACIFIC SCIENTIFIC ENERGETIC MATERIALS COMPANY (ARIZONA) LLC, a system composed of a box from which a harrow with multiple adjacent segments capable of being hinged is presented. This box can be positioned before the passage of the vehicle. On the Figures 5A and 5B , a foam is presented allowing both to protect the user against possible injuries inflicted by the flush points and to prevent the premature release of the points during deployment. The tips are detachable. When the fleeing vehicle passes, the harrow can be carried away.

In the patent US3235214 in the name of Sprung, a fixed barrier intended in particular to prevent the entry of an unauthorized vehicle into a parking lot is described, it allows the deployment of a series of fixed teeth. This presents a certain number of drawbacks: non-detachable teeth, impossibility of transport, etc.

In the utility model CN201250392 , a deployment system of a harrow with fixed points is presented.

In the request CN2633943 , a high barrier / harrow association system is presented.

In these last two prior arts, the system can be unbalanced, or even driven by the passage of the vehicle that one is trying to stop, which would lead to the need for fixing to the ground to avoid training.

A set of definitions relating to this description is given below.

The term “puncture module” means any element liable to puncture the tires of a fleeing vehicle once it is appropriately placed in an area where the tire of said fleeing vehicle will roll. The puncture module can be of variable size and shape, it can in particular comprise a means for grouping the puncture members, at least two positioning means and at least two puncture members. It can also be a product already on the market, such as the STOPSTICK® puncture modules with triangular section, PATROL TERMINATOR® or even BARRACUDA®. It can also be a puncture module capable of puncturing a tire whatever the side on which it rests, such as for example that presented in the Figure 1 demand US2014199118 in the name of Wersching or the STOPSTICK® puncture module with triangular section. When the puncture module is put in place on the road, a vehicle whose tires come into contact sees its travel slowed down, then stopped.

A “puncture member” is any element causing deterioration of the tire, this deterioration possibly being a puncture, a laceration or any other deterioration allowing the gas from the tire to leave the latter. When the puncture member is a point, it can be of any size, its section can be of any shape, the only imperative being that when it is inserted into the tire, it lets out the gas from the tire. It is therefore rigid. In particular, this can be ensured by means of a bore (hollow point), we will then speak of "point with axial bore", they can be of variable size and dimensions, it can also be double points like those described in Requirement US2014199118 . When it comes to blades, they can be of any shape and size.

The term “means of grouping puncture organs” is used to mean any element making it possible to keep the puncture organs sufficiently spaced apart to limit their number, but close enough so that at least one puncture organ damages the tire of the fleeing vehicle. It is a load-bearing plate of any shape and any size.

A “puncture member positioning means” is any element holding a puncture member in a position allowing it to present the puncture member to the tire of the fleeing vehicle at the desired angle, while being adapted and configured to allow the detachment of said puncture member, if the latter is for example sucked into the moving tire during its passage over the puncture module, and in general, at the same time as, or almost immediately, that the tire was damaged. By way of nonlimiting example, means for positioning the puncture members can be more or less circular orifices adapted to the puncture members, in particular when the puncture members have a more or less circular section such as for example spikes. The holes must be slightly larger than that of the section of the points, so that the points can come off or be caught during the passage of the fleeing vehicle once housed in the tire. The means of positioning the puncture members can be chosen from the group formed by the recesses, the additions of material and the separate elements secured to the grouping means. The separate elements secured to the grouping means can be of any kind, it can in particular be a point holder as described in the Figure 5A demand US2012 / 237293 under the reference 52, or else of blade holder. The positioning means can be completed by an element facilitating the detachment, such as for example the lubricant placed in the orifices, spring systems activated by the pressure of the tire, etc. As the puncture module only comprises positioning means, the puncture members are detachable.

The term “detachable puncture member”, or “easily detachable puncture member”, a puncture member whose vertical detachment is easy, for example whose vertical detachment requires a force in Newton (N) comparable to its weight. This is made possible for example by the association of a puncture member being a hollow point whose external section is circular and of a positioning means being a circular orifice whose diameter is slightly greater than the diameter of the section of the hollow point. Thus, during the passage of a fleeing vehicle, the point being free vertically, the detachment force will be mainly due to the weight of the point. It is important that the tip is free vertically precisely (and at least) at the time of post-puncture detachment. Thus, for example, a device of the STOPSTICK® type comprises points considered to be “detachable” according to the present application, insofar as at the time of the post-puncture detachment, the wheel has crushed the casing and the points are free vertically. In all cases, in the context of the present invention, a “detachable” puncture member systematically detaches more easily in a given situation than the puncture module.

A puncture member, may include a base secured to said member, for example a washer-shaped base, this base secured to a single member puncture can be compared to a "puncture member positioning means" according to the invention.

The term “compressible means of puncture protection means” means any material covering, at least in part, one or more puncture organ (s), it being understood that the means must be sufficiently compressible so that the puncture organ (s) can ( nt) damage the tire when passing a leaking vehicle. The compressible protective means can partially or completely cover the puncture organ (s). The compressible protection means can be fixed by means of grouping, for example by gluing, or only brought into contact with the latter. It can also cover only the ends of the puncture member (s), and therefore not be in contact with the grouping means. The compressible protective means has several roles: helping to maintain the puncture organs during the deployment of the puncture device (s) in order to avoid the premature dispersion of the said puncture organs, preventing the manipulating agent from being injured with the puncture means when handling the puncture module, hide the puncture devices from the driver of the fleeing vehicle until the puncture, etc. The compressible protective means may consist of a block of any compressible material, it may for example be chosen from the group consisting of polyurethane foams, blister cardboard, expanded polystyrene, and any other plastic / polymeric material having acceptable compression properties.

When the compressible protective means consists of a block of cellular material such as polyurethane foam or expanded polystyrene, the block may simply be placed on the puncture organ (s).

The term “support for said puncture module (s)” is used to mean any element located under the puncture module in the position of use, and intended to stabilize and maintain it. It may in particular be a plate of any shape and any size, suitable for the use. A support of said module (s) supports one or more puncture module (s). The underside of the puncture module (s) faces the upper face of the support, thus creating what is called an "interfacial zone". The support is linked to its puncture module (s) by means of what is called a "connection means which forms a privileged rupture zone". The support of said puncture module (s) is used to hold the puncture module (s) during the deployment of the device (s) on the road. Optionally, when the puncture module cannot be used on all its faces, the support is used to hold the useful face (or stop) in the position of use.

The term "rigid support for said puncture module (s)" means a support which does not deform or slightly deform during use, that is to say which has the same shape during the installation of the puncture system. puncture of a tire, during deployment, during the passage of the fleeing vehicle (s), when reloading the system in puncture module (s), as well as during storage of the system for reuse of said system in another place. It is understood that slight deformations are possible, especially during the passage of the fleeing vehicle, however they are limited. By way of example, the following materials can be used to manufacture a rigid support: steel, wood, etc., the support having to have a certain thickness. In particular if the support is made of stainless steel, its thickness must for example be greater than that described in column 4 lines 25-28 of the patent US 6,551,013 . The use of a rigid support ensures easier positioning of the puncture device, as well as good durability of the puncture device. In particular, the combination of a rigid support and a privileged rupture zone is preferred, because this makes it possible to have a robust puncture device while having a rupture zone preventing any projection and / or deterioration of the device.

We call "puncture device" the association of a support with one or more puncture module (s).

The term "connecting means which forms a privileged rupture zone" means any means making it possible to link the underside, or one of the faces when the puncture module is liable to puncture a tire whatever the face on which it rests, as for example example the one presented in the figure 1 demand US2014199118 , and the upper face of the support. This connection forms a privileged rupture zone, because it has the capacity to rupture during the passage of the fleeing vehicle or when it is desired to reload the support in puncture module (s). The resistance of the bonding of the bonding means which forms a privileged rupture zone is assessed by the adhesion force during a cleavage, it is expressed in N / cm ² of interfacial zone.

The term “privileged rupture” zone is understood to mean an zone which, when the device is subjected to a shock, will be broken according to the violence of the shock. This area can be broken. This area can be broken if the shock is relatively violent. This rupture protects the entire device and withstand the shock. The resistance being limited there is no risk of destruction of the device or risk of entrainment thereof. Only the modules which are in any case to be changed after each use risk being detached and driven.

The preferred rupture zone plays a real role of "fuse", that is to say that according to the conditions of use (in particular according to the speed of the vehicle fleeing, depending on the type of vehicle fleeing, depending on the type of tire, etc.), this zone will give or not give rise to a rupture, so when the impact is of a relative violence, the rupture of the preferred rupture zone will preserve the puncture device, as well as more generally (and if necessary) the puncture system, from deterioration.

Due to the presence of “compressible protective means”, the tips are neutralized and there is no risk of injury or scattering of the puncture organs during handling. In addition, due to the presence of this rupture zone, the modules can be easily and quickly detached by a manipulator in order to replace them.

A “connection means which forms a privileged rupture zone” ensures a connection at least during the deployment of the device (s). Indeed, in the case for example where the connecting means is an electromagnet, the latter can ensure a connection during the deployment of the device (s), the puncture modules being left free from the device (s) of flat tire deployed, even before the fleeing vehicle passes. This will be particularly suitable when the puncture modules used can be used on all sides, this is the case for example of the STOPSTICK® puncture module with triangular section usable on all three sides.

The term “damping means” is used to designate any element making it possible to reduce shocks during the deployment of the puncture device (s) on the road. The damping means is therefore generally disposed between the support and the ground when the device (s) are deployed. It can be of any compatible material, in particular rubber. The damping means may be present on the entire underside of the support, or only on a part of this face. Preferably, the damping means is present on substantially the entire underside of the support, so the support is not deformed, even after multiple passages of fleeing vehicles.

As indicated above, the puncture modules are positioned on the support, so that the support of the device has a zone free of any puncture module, on either side thereof. This free zone is delimited in two parts, namely a distance designated “pre-contact distance”, corresponding to the distance between an upstream edge of the support and an upstream edge of the puncture module, and a second distance designated, “distance from post-contact ”, corresponding to a distance between a downstream edge of the puncture module and a downstream edge of the support. When we speak of an upstream edge, it is the edge of the corresponding element which is touched first by the tire of the moving vehicle in a given trajectory. In the same way, the downstream edge is the edge of the element correspondent from which the vehicle tire loses the last contant, according to its movement trajectory.

Generally, the pre-contact distance is less than the post-contact distance, in order to facilitate the detachment of the puncture devices with the vehicle tire support point on the support.

“Tire puncture system” is any assembly comprising one or more puncture device (s) according to the definition given above, and allowing the puncture device (s) and the module (s) ) puncture to be properly positioned on the road. This assembly can for example consist of one or more puncture device (s), a means of receiving said puncture (s), a means of stabilization of said reception means, means for releasing said puncture device (s) and means for controlling said release means, a puncture device being connected to said stabilization means by means of a first articulation means. When there are several puncture devices, they can also be linked to one another by means of one or more articulation means. The puncture system is the most encompassing entity, a puncture system comprises one or more puncture device (s), said puncture device (s) comprising (each) one or more puncture module (s).

The term “means of reception of said puncture device (s)” means any element having an adequate volume allowing the disposition of said puncture device (s) therein, pending their deployment. It can for example be a hollow post, a small house, a trash can, a hollowed-out tree trunk, or even any other element having a sufficient volume and being commonly encountered in roadsides. Thus, before the deployment of the puncture device (s), the reception means will not arouse the attention of the driver of the fleeing vehicle.

The term "means for stabilizing said reception means" means any element allowing the reception means to be stable before, during and after the deployment of said puncture device (s). The means of stabilization must be adapted to the means of reception. For example, when the reception means is a hollow post, the stabilization means can be a base of suitable mass and dimensions.

The term “means for releasing said puncture device (s)” is any element allowing the deployment of said puncture device (s) on the road. It can for example be an electromagnet, or any other mechanical release means, such as for example a hook as mentioned in the application. CN201250392 . In one embodiment, it is an electromagnet must be energized so that the device (s) is (are) deployed, which prevents accidental deployment in the event of a power failure.

The term “means for controlling said release means” means any element transmitting information, in particular of a mechanical or electronic nature, to the release means. It can in particular be a push button, or a remote control for remote control, etc. When the control means of said release means is activated, said release means allows the deployment of the puncture device (s) on the road.

The control means controls the release means. This control can in particular be carried out by means of an electronic circuit.

Surprisingly, it has been demonstrated that a puncture device comprising one or more puncture module (s) having none of the drawbacks mentioned could be produced.

Surprisingly, it has been demonstrated that a puncture system comprising one or more puncture device (s) according to the invention and having none of the drawbacks mentioned could be achieved.

• sécurité ;
  Le dispositif de crevaison objet de l'invention présente une sécurité optimale, dans la mesure où aucune projection du dispositif ne peut avoir lieu. En outre, l'intégrité du dispositif est maintenue quelle que soit la vitesse de passage du véhicule fuyard et sa nature (voiture, camion, bus, etc.) grâce au moyen de liaison qui forme une zone de rupture privilégiée. La sécurité du conducteur du véhicule fuyard est également assurée.
• rechargement ;
  Le dispositif de crevaison objet de l'invention peut être facilement rechargé en module(s) de crevaison grâce au moyen de liaison qui forme une zone de rupture privilégiée, le manipulateur pouvant remplacer les modules de crevaisons utilisés (si ceux-ci sont restés en place) par des nouveaux, ceci est tout particulièrement appréciable dans le cas de multiples véhicules fuyards passant au même endroit à intervalles de temps relativement courts.
• performance de crevaison ;
  Le dispositif de crevaison selon l'invention maintient les organes de crevaison, pouvant être des pointes, bien droites sur le plan vertical, ces pointes sont facilement détachables et ne peuvent être « couchées » au passage du véhicule fuyard. Ainsi, toutes les pointes sont susceptibles de crever les pneus du véhicule fuyard, dans la mesure où ce dernier passe dessus. En outre, l'association maintien vertical/facilité de décrochement rend adapté le dispositif objet de l'invention à un grand panel de véhicules (voitures, camions, bus, etc.) et de situation, en particulier à des vitesses très variables d'un véhicule à l'autre.
• dispositif universel ;
  Contrairement à certains produits sur le marché, le dispositif de crevaison selon l'invention est adapté à un grand panel de véhicules circulant (voitures, camions, bus, etc.) roulant à des allures variables ;
• préservation du dispositif de crevaison ainsi que du système de crevaison / performances de crevaison ;
  Le dispositif de crevaison présente au moins un organe de crevaison facilement détachable, ainsi qu'une zone de rupture privilégiée. L'au moins un organe de crevaison facilement détachable se détache systématiquement et reste dans le pneu. Par ailleurs, selon les conditions de crevaison (en particulier selon la vitesse du véhicule fuyard, selon le type de véhicule fuyard, selon le type de pneu, etc.), cette zone de rupture privilégiée donnera ou ne donnera pas lieu à une rupture, ainsi lorsque le choc est d'une relative violence, la rupture de la zone de rupture privilégiée préservera le dispositif de crevaison, ainsi que plus généralement (et le cas échéant) le système de crevaison, d'une détérioration.
• crevaison de plusieurs pneus du même véhicule ;
  Etant donné que le dispositif de crevaison ainsi que plus généralement (et le cas échéant) le système de crevaison sont préservés de toute détérioration, le dispositif de crevaison est susceptible de crever plusieurs pneus du même véhicule fuyard. Dans certains modes de réalisation, par exemple, le second pneu touché peut avoir roulé sur le même module de crevaison (dans le cas d'une non-rupture de la zone de rupture privilégiée lors du contact avec le premier pneu touché, d'autres organes de crevaison n'ayant pas crevé le premier pneu touché peuvent crever le second pneu touché) ou sur un module de crevaison différent.

As regards the puncture device according to the invention, it has the following advantageous characteristics:

• security ;
  The puncture device which is the subject of the invention has optimum safety, insofar as no projection of the device can take place. In addition, the integrity of the device is maintained whatever the speed of passage of the fleeing vehicle and its nature (car, truck, bus, etc.) thanks to the connection means which forms a privileged rupture zone. The safety of the driver of the fleeing vehicle is also ensured.
• reloading;
  The puncture device which is the subject of the invention can be easily recharged in puncture module (s) thanks to the connection means which forms a privileged rupture zone, the manipulator being able to replace the puncture modules used (if these have remained in place) by new ones, this is particularly appreciable in the case of multiple fleeing vehicles passing in the same place at relatively short time intervals.
• puncture performance;
  The puncture device according to the invention holds the puncture members, which can be spikes, very straight on the vertical plane, these spikes are easily detachable and cannot be "laid down" as the fleeing vehicle passes. Thus, all the points are liable to puncture the tires of the fleeing vehicle, insofar as the latter passes over it. In addition, the combination of vertical hold / ease of unhooking makes the device which is the subject of the invention suitable for a large panel of vehicles (cars, trucks, buses, etc.) and of situation, in particular at very variable speeds from one vehicle to the other.
• universal device;
  Unlike certain products on the market, the puncture device according to the invention is suitable for a large panel of circulating vehicles (cars, trucks, buses, etc.) traveling at variable speeds;
• preservation of the puncture device as well as the puncture system / puncture performance;
  The puncture device has at least one easily detachable puncture member, as well as a privileged rupture zone. The at least one easily detachable puncture member systematically detaches and remains in the tire. Furthermore, depending on the puncture conditions (in particular according to the speed of the fleeing vehicle, according to the type of fleeing vehicle, according to the type of tire, etc.), this preferred rupture zone will or will not give rise to a rupture, thus when the shock is of a relative violence, the rupture of the privileged rupture zone will preserve the puncture device, as well as more generally (and if necessary) the puncture system, from deterioration.
• puncture of several tires on the same vehicle;
  Since the puncture device as well as more generally (and if applicable) the puncture system are preserved from any deterioration, the puncture device is liable to puncture several tires from the same fleeing vehicle. In certain embodiments, for example, the second tire affected may have rolled on the same puncture module (in the case of non-rupture of the preferred rupture zone during contact with the first tire affected, others puncture devices which have not punctured the first affected tire may puncture the second affected tire) or on a different puncture module.

As for the puncture system, it also has a number of advantages.

First of all, it is easily transportable, since it just has to be placed on the side of the road without any particular fixing.

Then he is very discreet. The deployment of the puncture device (s) is rapid, and can even be controlled remotely.

S'agissant du module de crevaison 18, il est composé d'un moyen de regroupement des organes de crevaison 14, ledit moyen de regroupement des organes de crevaison 14 étant une plaque porteuse ayant une longueur d, une largeur e, ainsi qu'une épaisseur c. Cette plaque porteuse est perforée par des orifices constituant des moyens de positionnement 15 d'organes de crevaison 16, lesdits organes de crevaison 16 étant des pointes à alésage axial. Lesdites pointes à alésage axial sont espacées d'une longueur f, elles ont un diamètre légèrement inférieur (d'environ 0,07 cm) à celui desdits orifices, elles ont une hauteur libre g. Un moyen de protection compressible couvrant 17 qui est une mousse est également représenté, cette mousse est destinée à recouvrir, au moins en partie, les pointes à alésage axial, elle est représentée en vue éclatée afin de pouvoir représenter les pointes et les orifices. La mousse a une longueur k, une largeur l, ainsi qu'une épaisseur j. Le module de crevaison 18 présente, sur la face inférieure I, un moyen de liaison qui forme une zone de rupture privilégiée 13 étant une bande de velcro (ruban auto aggripant) 13b. Le support 12 du module de crevaison 18 présente, sur sa face supérieure S, un moyen de liaison qui forme une zone de rupture privilégiée 13 étant le velcro complémentaire (ruban auto aggripant) 13a ayant une largeur h. Ledit support 12 repose sur un moyen d'amortissement 11 étant une plaque en caoutchouc ayant une épaisseur a. Le support 12 présente une largeur i et une épaisseur m. La bande de velcro 13a du support 12 présente une largeur h. Lorsqu'un véhicule fuyard roule sur l'extrait de dispositif de crevaison 1 présenté dans la Figure 1, le pneu écrase la mousse, permettant ainsi à une portion significative de la hauteur libre g des pointes à alésage axial de se loger dans le pneu. A partir de ce moment, le gaz se trouvant dans le pneu sort par l'intermédiaire de l'alésage axial des pointes à alésage axial. Lorsque le pneu dépasse le module de crevaison 18, les pointes restent logées dans le pneu et se détachent du moyen de regroupement, ledit moyen de regroupement 14 étant une plaque porteuse, par l'intermédiaire du moyen de positionnement 15, ledit moyen de positionnement 15 étant un orifice dont le diamètre est plus important que celui des pointes à alésage axial. La longueur pré-contact b et la longueur post-contact n sont telles que b < n. En effet, une fois que les pointes à alésage axial sont logées dans le pneu, il est nécessaire que le pneu prenne appui sur le support 12 dans la zone post-contact afin de créer un effet de levier permettant aux pointes de se détacher sans causer de dommages audit support 12. Ainsi, le support 12 du module de crevaison 18 n'est pas endommagé, le module de crevaison 18 peut en outre être rechargé rapidement en moyen(s) de crevaison 16 étant des pointes et/ou remplacé par un autre module de crevaison 18 préassemblé. Dans certaines conditions particulières, par exemple si le véhicule fuyard roule à vive allure, le moyen de liaison qui forme une zone de rupture privilégiée 13 est susceptible de permettre le détachement dudit moyen de regroupement 14 étant une plaque porteuse du support 12 étant une plaque rigide. Ceci permet de préserver l'intégrité du support 12 et de pouvoir le recharger en modules de crevaison 18 préassemblés dans le cas où au moins un module de crevaison 18 est emporté par le véhicule fuyard. Ainsi, le moyen de liaison qui forme une zone de rupture privilégiée 13 joue un véritable rôle de « fusible » (rupture ou non selon la violence du choc), permettant de préserver l'intégrité et de maintenir la durabilité du support 12 et la possibilité de le recharger rapidement en modules de crevaison 18 quel que soit le type de véhicule fuyard, quelle que soit sa vitesse.

  La Figure 2 représente une vue simplifiée d'un système de crevaison 20 selon l'invention, comprenant un unique dispositif de crevaison 1. Le déploiement du dispositif de crevaison 1 est représenté par la flèche recourbée. Le premier moyen formant articulation 23 existant entre le dispositif de crevaison 1 et le moyen de stabilisation 22 du système de crevaison 20 permet au dispositif de crevaison 1 de se déployer d'une position verticale vers une position horizontale (sur la route). Une fois que le système 20 a servi à arrêter un véhicule fuyard, le dispositif de crevaison 1 peut être replié dans le moyen d'accueil 21. Le temps de déploiement est de l'ordre de 0,5 seconde.
• Figure 3 : Vue simplifiée d'un système de crevaison selon l'invention déployant deux dispositifs de crevaison
  La Figure 3 représente une vue simplifiée similaire à celle de la Figure 2, la différence étant que le système ne comprend pas un mais deux dispositifs de crevaison 1, lesdits dispositifs de crevaison 1 étant articulés par un second moyen formant articulation 24.
  Lorsque les deux dispositifs se déploient, les moyens formant articulation 23 et 24 font évoluer les éléments les uns par rapport aux autres, le premier moyen formant articulation 23 faisant évoluer le premier dispositif par rapport au moyen de stabilisation 22, et le second moyen formant articulation 24 faisant évoluer le premier dispositif de crevaison 1 par rapport au second dispositif de crevaison 1.
  Sur la Figure 3 sont représentées trois flèches recourbées, elles représentent le déploiement des deux dispositifs de crevaison 1. Les mouvements qu'elles décrivent ont lieu, au moins en partie, simultanément. Le temps de déploiement est de l'ordre de 1,5 secondes.
• Figure 4 : Vue extérieure d'un système de crevaison selon l'invention
  La Figure 4 représente un système de crevaison 20 selon l'invention, il se compose d'un moyen d'accueil 21 des dispositifs de crevaison 1, ledit moyen d'accueil 21 étant un poteau creux ayant une largeur p et une hauteur q, d'un moyen de stabilisation 22 dudit moyen d'accueil 21, ledit moyen de stabilisation 22 étant une embase, d'un moyen de libération 26 desdits dispositifs de crevaison 1, ledit moyen de libération 26 étant un électro-aimant, d'un moyen de commande 25 dudit moyen de libération, ledit moyen de commande 25 étant une télécommande. Le système de crevaison 20 présente, pour chacun des deux dispositifs de crevaison 1, quatre modules de crevaison 18 dont les deux supports 12 qui sont des plaques en acier reposent sur un moyen d'amortissement 11 qui est une plaque en caoutchouc. La première plaque a une longueur s et la seconde plaque a une longueur o, s étant supérieur à o. Deux moyens formant articulation 23 et 24 sont représentés, un premier moyen formant articulation 23 liant le moyen de stabilisation étant une embase et le premier dispositif de crevaison 1, un second moyen formant articulation 24 liant le premier dispositif de crevaison 1 et le second dispositif de crevaison 1. Lorsqu'un véhicule fuyard est repéré, le système de crevaison 20 est disposé au bord de la route. A l'approche du véhicule fuyard, l'activation du moyen de commande 25 qui est une télécommande permet la libération desdits dispositifs de crevaison 1 par l'intermédiaire du moyen de libération 26 desdits dispositifs de crevaison 1, ledit moyen de libération 26 étant un électro-aimant. Les deux dispositifs de crevaison 1 sont alors déployés sur la route. Le sens de circulation du véhicule fuyard est représenté par la flèche de plus grand épaisseur. Le déploiement est optimisé par l'utilisation de moyens formant articulation 23 et 24 pourvus de moyens de stockage d'énergie de déploiement 27 et 28, lesdits moyens de stockage de l'énergie étant des ressorts. Ainsi le conducteur de véhicule fuyard ne pourra pas éviter l'endommagement de ses pneus, car le déploiement se fera très peu de temps avant le contact entre les pneus du véhicule fuyard et les modules de crevaison 18. Lorsque le véhicule fuyard roule sur les modules de crevaison 18, les pneus se dégonflent progressivement, assurant l'arrêt progressif mais certain du véhicule fuyard tout en préservant la sécurité de son/ses passager(s)/conducteur. Après le passage du véhicule fuyard, les dispositifs de crevaison 1 peuvent être repliés dans le moyen d'accueil 21 des dispositifs de crevaison 1, ledit moyen d'accueil étant un poteau creux.
• Figure 5 : Vue extérieure d'un système de crevaison selon l'invention
  La Figure 5 représente un système de crevaison 20 selon l'invention, elle diffère de la Figure 4 en ce que le système comprend un seul dispositif de crevaison 1.

  La Figure 6 représente un dispositif de crevaison 1 selon l'invention, lors du passage d'un véhicule fuyard. Le sens de circulation du véhicule fuyard est représenté par la grosse flèche.
  La roue du véhicule fuyard est pourvue d'un pneu 29. Le pneu 29 a été perforé par les organes de crevaison 16 étant des pointes à alésage axial lors de son passage sur le module de crevaison 1.
  La Figure 6 illustre que lorsque les organes de crevaison 16 qui sont des pointes à alésage axial sont logées dans le pneu, elles peuvent d'autant mieux être détachées sans endommager le reste du dispositif de crevaison que le pneu 29, lors d'au moins une partie de la phase d'arrachage, prend appui sur le support 12 en aval du module de crevaison.
  Il est notable que les proportions n'ont pas systématiquement été respectées dans la Figure 6, ceci ayant pour but de représenter un module de crevaison 18 (et ses composants) de manière détaillée. Dans des proportions réelles, par rapport à la roue, le module de crevaison est sensiblement plus petit.
• Figure 7 : vues de côté d'un dispositif de crevaison selon l'invention lors du passage d'un véhicule fuyard (cas où le module de crevaison n'est pas emporté)
  La figure 7 représente un dispositif de crevaison 1 selon l'invention, lors du passage d'un véhicule fuyard. Le dispositif de crevaison correspond à celui décrit dans la Figure 1. Le sens de circulation du véhicule est représenté par la grosse flèche.
  Les Figure 7a, 7b et 7c correspondent à une séquence temporelle.
  Dans la figure 7a, il est visible un pneu 29 d'un véhicule fuyard roulant sur une route 100.
  Dans la figure 7b, il est visible un dispositif de crevaison 1 selon l'invention, comprenant un module de crevaison 18. A ce stade, le pneu 29 a roulé sur le dispositif de crevaison 1, et en particulier sur le module de crevaison 18, et notamment sur le moyen de protection compressible 17. Les organes de crevaison 16, qui sont des pointes creuses, ont perforé le pneu 29, le pneu 29 prend appui sur la distance post-contact n.
  Dans la figure 7c, il est visible le pneu 29 du véhicule fuyard ayant dépassé le dispositif de crevaison 1 selon l'invention. Les organes de crevaison 16, qui sont des pointes creuses, sont logés dans le pneu 29 du véhicule fuyard et l'air s'échappe dudit pneu 29 du véhicule fuyard. Dans le mode de réalisation présenté à la figure 7c, le module de crevaison 18 est resté accroché au support 12 dudit module de crevaison 18. Dans d'autres conditions de crevaison (en particulier selon la vitesse du véhicule fuyard, selon le type de véhicule fuyard, selon le type de pneu, etc.), le module de crevaison 18 aurait pu se détacher du support 12 dudit module de crevaison 18, en ce qu'ils sont liés par un moyen de liaison qui forme une zone de rupture privilégiée 13.
• Figure 8 : vues de côté d'un dispositif de crevaison selon l'invention lors du passage d'un véhicule fuyard (cas où le module de crevaison est emporté)
  La Figure 8 est similaire à la Figure 7, mais contrairement au cas présenté dans la Figure 7, ici le module de crevaison 18 est arraché par le pneu 29 du véhicule fuyard. Ceci est dû au fait que d'autres conditions de crevaison sont présentes (vitesse du véhicule fuyard différente, type de véhicule fuyard différent, type de pneu différent, etc.)

In order to illustrate the invention, the Figures 1 to 5 are described below.

• Figure 1 : Exterior view of a puncture device according to the invention
  The Figure 1 shows an extract of puncture device 1 according to the invention comprising a puncture module 18 having a lower face I, a support 12 of the puncture module 18 being a rigid plate having an upper face S and a width i. The two faces I and S are opposite at an interfacial zone ZI. As regards the puncture module 18, it is composed of a means for grouping the puncture members 14, said means for grouping the puncture members 14 being a carrier plate having a length d, a width e, as well as a thickness c. This carrier plate is perforated by orifices constituting positioning means 15 of puncture members 16, said puncture members 16 being points with axial bore. Said points with axial bore are spaced apart by a length f, they have a diameter slightly smaller (about 0.07 cm) than that of said orifices, they have a free height g. A compressible protective means covering 17 which is a foam is also shown, this foam is intended to cover, at least in part, the points with axial bore, it is shown in exploded view in order to be able to represent the points and the orifices. The foam has a length k, a width l, and a thickness j. The puncture module 18 has, on the lower face I, a connecting means which forms a privileged rupture zone 13 being a strip of velcro (self-gripping tape) 13b. The support 12 of the puncture module 18 has, on its upper face S, a connecting means which forms a privileged rupture zone 13 being the complementary velcro (self-gripping tape) 13a having a width h. Said support 12 rests on a damping means 11 being a rubber plate having a thickness a. The support 12 has a width i and a thickness m. The velcro strip 13a of the support 12 has a width h. When a fleeing vehicle is traveling on the puncture device extract 1 presented in the Figure 1 , the tire crushes the foam, thus allowing a significant portion of the free height g of the points with axial bore to lodge in the tire. From this moment, the gas in the tire leaves via the axial bore of the axially bored tips. When the tire exceeds the puncture module 18, the points remain housed in the tire and detach from the grouping means, said grouping means 14 being a carrier plate, by means of positioning means 15, said positioning means 15 being an orifice whose diameter is larger than that of the points with axial bore. The pre-contact length b and the post-contact length n are such that b <n. Indeed, once the points with axial bore are housed in the tire, it is necessary for the tire to bear on the support 12 in the post-contact zone in order to create a leverage effect allowing the points to detach without cause damage to said support 12. Thus, the support 12 of the puncture module 18 is not damaged, the puncture module 18 can also be quickly recharged with puncture means 16 being spikes and / or replaced by another preassembled puncture module 18. Under certain specific conditions, for example if the fleeing vehicle is traveling at high speed, the connection means which forms a privileged rupture zone 13 is capable of allowing the detachment of said regrouping means 14 being a carrier plate of the support 12 being a rigid plate . This makes it possible to preserve the integrity of the support 12 and to be able to recharge it in preassembled puncture modules 18 in the event that at least one puncture module 18 is carried away by the fleeing vehicle. Thus, the connecting means which forms a privileged rupture zone 13 plays a real role of "fuse" (rupture or not depending on the severity of the impact), making it possible to preserve the integrity and maintain the durability of the support 12 and the possibility to quickly recharge it in puncture modules 18 whatever the type of fleeing vehicle, whatever its speed.
• Figure 2 : Simplified view of a puncture system according to the invention deploying a single puncture device
  The Figure 2 shows a simplified view of a puncture system 20 according to the invention, comprising a single puncture device 1. The deployment of the puncture device 1 is represented by the curved arrow. The first articulation means 23 existing between the puncture device 1 and the stabilization means 22 of the puncture system 20 allows the puncture device 1 to deploy from a vertical position to a horizontal position (on the road). Once the system 20 has been used to stop a fleeing vehicle, the puncture device 1 can be folded back into the reception means 21. The deployment time is of the order of 0.5 seconds.
• Figure 3 : Simplified view of a puncture system according to the invention deploying two puncture devices
  The Figure 3 represents a simplified view similar to that of the Figure 2 , the difference being that the system does not include one but two puncture devices 1, said puncture devices 1 being articulated by a second articulation means 24.
  When the two devices are deployed, the articulation means 23 and 24 cause the elements to evolve relative to one another, the first articulation means 23 causing the first device to evolve relative to the means of stabilization 22, and the second articulation means 24 causing the first puncture device 1 to evolve relative to the second puncture device 1.
  On the Figure 3 three bent arrows are shown, they represent the deployment of the two puncture devices 1. The movements they describe take place, at least in part, simultaneously. The deployment time is around 1.5 seconds.
• Figure 4 : Exterior view of a puncture system according to the invention
  The Figure 4 shows a puncture system 20 according to the invention, it consists of a receiving means 21 of the puncturing devices 1, said receiving means 21 being a hollow post having a width p and a height q, of a stabilization means 22 of said receiving means 21, said stabilization means 22 being a base, of a release means 26 of said puncture devices 1, said release means 26 being an electromagnet, of a control means 25 of said release means, said control means 25 being a remote control. The puncture system 20 has, for each of the two puncture devices 1, four puncture modules 18 of which the two supports 12 which are steel plates rest on a damping means 11 which is a rubber plate. The first plate has a length s and the second plate has a length o, s being greater than o. Two articulation means 23 and 24 are shown, a first articulation means 23 connecting the stabilization means being a base and the first puncture device 1, a second articulation means 24 linking the first puncture device 1 and the second puncture device puncture 1. When a fleeing vehicle is spotted, the puncture system 20 is located on the side of the road. When approaching the fleeing vehicle, the activation of the control means 25 which is a remote control allows the release of said puncture devices 1 via the release means 26 of said puncture devices 1, said release means 26 being a electro magnet. The two puncture devices 1 are then deployed on the road. The direction of movement of the fleeing vehicle is represented by the arrow of greater thickness. The deployment is optimized by the use of articulation means 23 and 24 provided with deployment energy storage means 27 and 28, said energy storage means being springs. Thus the driver of a fleeing vehicle will not be able to avoid damaging his tires, because deployment will take place very shortly before contact between the tires of the fleeing vehicle and the puncture modules 18. When the fleeing vehicle is traveling on the modules puncture 18, the tires gradually deflate, ensuring the gradual but certain stop of the fleeing vehicle while preserving the safety of his / her passenger (s) / driver. After the fleeing vehicle has passed, the puncture devices 1 can be folded back into the reception means 21 of the puncture devices 1, said reception means being a hollow post.
• Figure 5 : Exterior view of a puncture system according to the invention
  The Figure 5 represents a puncture system 20 according to the invention, it differs from the Figure 4 in that the system comprises a single puncture device 1.
• Figure 6 : Side view of a puncture device according to the invention
  The Figure 6 shows a puncture device 1 according to the invention, during the passage of a fleeing vehicle. The direction of movement of the fleeing vehicle is represented by the large arrow.
  The wheel of the fleeing vehicle is provided with a tire 29. The tire 29 has been punctured by the puncture members 16 being points with axial bore when it passes over the puncture module 1.
  The Figure 6 illustrates that when the puncture members 16 which are points with axial bore are housed in the tire, they can be detached all the better without damaging the rest of the puncture device than the tire 29, during at least part of the lifting phase, is supported on the support 12 downstream of the puncture module.
  It is notable that the proportions were not systematically respected in the Figure 6 , this aim being to represent a puncture module 18 (and its components) in detail. In real proportions, relative to the wheel, the puncture module is significantly smaller.
• Figure 7 : side views of a puncture device according to the invention during the passage of a fleeing vehicle (case where the puncture module is not carried away)
  The figure 7 shows a puncture device 1 according to the invention, during the passage of a fleeing vehicle. The puncture device corresponds to that described in the Figure 1 . The direction of movement of the vehicle is represented by the large arrow.
  The Figure 7a, 7b and 7c correspond to a time sequence.
  In the figure 7a , it is visible a tire 29 of a fleeing vehicle traveling on a road 100.
  In the figure 7b , a puncture device 1 according to the invention is visible, comprising a puncture module 18. At this stage, the tire 29 has rolled on the puncture device 1, and in particular on the puncture module 18, and in particular on the compressible protective means 17. The puncture members 16, which are hollow points, have punctured the tire 29, the tire 29 is supported on the post-contact distance n.
  In the figure 7c , it is visible the tire 29 of the leaking vehicle having exceeded the puncture device 1 according to the invention. The puncture members 16, which are hollow points, are housed in the tire 29 of the fleeing vehicle and the air escapes from said tire 29 of the fleeing vehicle. In the embodiment presented to the figure 7c , the puncture module 18 remained attached to the support 12 of said puncture module 18. In other puncture conditions (in particular according to the speed of the fleeing vehicle, according to the type of fleeing vehicle, according to the type of tire, etc. ), the puncture module 18 could have detached from the support 12 of said puncture module 18, in that they are linked by a connecting means which forms a privileged rupture zone 13.
• Figure 8 : side views of a puncture device according to the invention during the passage of a fleeing vehicle (case where the puncture module is carried away)
  The Figure 8 is similar to the Figure 7 , but unlike the case presented in the Figure 7 , here the puncture module 18 is torn off by the tire 29 of the fleeing vehicle. This is due to the fact that other puncture conditions are present (different speed of the leaking vehicle, different type of leaking vehicle, different type of tire, etc.)

The Figure 8a, 8b, 8c and 8d correspond to a time sequence.

The Figure 8a is identical to the Figure 7a , the tire 29 not having rolled on the puncture module 18.

In the Figure 8b , a puncture device 1 according to the invention is visible, comprising a puncture module 18. At this stage, the tire 29 has rolled on the puncture device 1, and in particular on the puncture module 18, and in particular on the compressible protective means 17. The puncture members 16, which are hollow points, have perforated the tire 29, the tire 29 is supported on the post-contact distance n.

In the Figure 8c , it is visible that the puncture module 18 has detached from the support 12. The puncture module 18 can be taken away. This is due to the fact that other puncture conditions are present (different speed of the leaking vehicle, different type of leaking vehicle, different type of tire, etc.).

In the Figure 8d , it is visible that the puncture module is detached from the wheel under the effect of centrifugal force and the pressure exerted by the compressible protective means 17. The puncture module 18 is therefore no longer visible. The puncture members 16 remain housed in the tire during deflation. The tire is more deflated than in the representation of the Figure 8c , that more time has passed since the puncture.

As seen above, the invention relates to both a tire puncture device 1, a tire puncture system 20, a method of stopping of a fleeing vehicle (characterized in that it comprises the positioning of a device 1 according to the invention so that at least one puncture module 18 is in contact with at least one tire of the fleeing vehicle when the latter passes).

The operation of the puncture device 1 according to the invention (included or not in a puncture system 20 according to the invention) is explained in detail below.

When an operator is warned of the imminent passage of a fleeing vehicle, the latter positions the device 1 (and, if applicable, the system 20) on the side of the road that the fleeing vehicle is about to walk alongside, the module puncture 18 must be substantially perpendicular to the road (orientation most appropriate a priori vis-à-vis the trajectory of the fleeing vehicle).

In the case of the use of a puncture system 20 according to the invention, the latter is actuated by means of the control means 25, shortly before the passage of the fleeing vehicle, so that the fleeing vehicle neither detects the system 20 , nor the device 1 too early, the device 1 is then positioned substantially perpendicular to the road.

The puncture module 18 of the puncture device 1 is then able to puncture the tires 29 of a fleeing vehicle. When the tire 29 passes over the puncture module 18, the compressible protective means covering 17 (which is for example a foam) is compressed, thus leaving the puncture members 16 being for example hollow (rigid) points puncturing the tire 29 of the fleeing vehicle. The deflation of the tire 29 of the fleeing vehicle then begins, the air escaping through the bore produced in the point (“hollow” point). The puncture members 16 are all the more easily detached from the puncture module 18, and more particularly from the positioning means 15 (which may for example be a hole), as the tire 29 bears on the post-contact length n located downstream of the puncture module 1 in the direction of the trajectory of the fleeing vehicle. When the puncture members 16 are detached, the puncture module 18 having a lower face I can be detached from the puncture device 1, and more particularly from the support 12 of said puncture module 18 having an upper face S. This detachment is made possible by the connecting means which forms a privileged rupture zone 13 situated in the interfacial zone ZI (on which the faces I and S are opposite).

Thus, according to the violence of the impact (in particular according to the speed of the fleeing vehicle, according to the type of fleeing vehicle, according to the type of tire 29, etc.), the puncture module 18 will come off or will not come off.

The puncture of the tire 29 by at least one puncture member 16 causes the tire to deflate, starting from the puncture. Time to tire deflation is very variable, for information the tire can be deflated after a few seconds, or after a minute, the deflation time depending on a large number of factors (number of punctures 16 housed in tire 29, type of bore, initial tire pressure, etc.). The tire is deflated when the pressure inside the tire 29 is similar to the pressure outside the tire 29.

The puncture device 1 of a tire according to the invention can then be “recharged” in puncture module (s) 18, the module (s) to be replaced being those having given rise to the puncture.

Alternatively, when only some of the puncture members 16 of the puncture module 18 have been introduced into the tire 29 (or when the puncture members 18 have been able to be recovered by any means), it may be possible to reload only with organs puncture 16, without replacing the entire puncture module 18 (the other elements of the puncture module must also be available). Preferably, the puncture device 1 according to the invention will be recharged directly in puncture module (s) 18, whatever the situation, since this presents less risk of injury, recharging is faster, etc.

Then, in the case of the use of a puncture system 20 according to the invention, the puncture device (s) 1 can be folded up in the reception means 21, said puncture system 20 is therefore reusable, either on a different day or immediately (in the case of following leaking vehicles, such as “go-fast” for example).

Example 1 : puncture test

A puncture test using a system according to the invention comprising a puncture device corresponding to the Figure 1 was conducted on a panel of different vehicles, traveling at different speeds. The results are shown in Table 1 below: <b> Table 1 </b> Vehicle type Number of wheels Impact speed Puncture Failure of the preferred rupture zone Car (mass: about 1000 kg) 4 10 km / h Yes no Car (mass: about 1000 kg) 4 60 km / h Yes Yes Truck (mass: about 28,000 kg) 10 80 km / h Yes Yes

It should be noted that whatever the experimental conditions, the tires of the vehicles were systematically punctured. Depending on the experimental conditions, the preferred rupture zone has been broken or not, thus preserving the system according to the invention.
