Description

L'invention relève du domaine de la protection passive contre des projectiles. L'invention propose un dispositif de protection anti-souffle, anti-fragment, anti-balle, anti-ricochet et anti-véhicule biface.The invention relates to the field of passive protection against projectiles. The invention provides an anti-blast, anti-fragment, anti-bullet, anti-ricochet and anti-two-sided vehicle protection device.

Des dispositifs visant à confiner in situ un objet dangereux dans l'attente de son traitement par un service compétent ont été mis au point, cf WO2004001329 et WO2009130398 .Devices aimed at confining a dangerous object in situ while awaiting its treatment by a competent service have been developed, cf. WO2004001329 and WO2009130398 .

FR 2 855 606 décrit un paravent anti-explosion déployable en portion de polygone. Le paravent est efficace pour des charges explosives légères et n'est pas conçu pour un service permanent. FR 2 855 606 describes an explosion-proof screen that can be deployed as a portion of a polygon. The draft shield is effective for light explosive charges and is not designed for permanent service.

FR 2 854 685 concerne une protection mobile temporaire. L'emprise au sol est relativement importante. FR 2 854 685 concerns temporary mobile protection. The footprint is relatively large.

WO 2009/035637 concerne un séparateur central d'autoroute comprenant une base en béton préexistante avec des faces latérales en pente et un sous-ensemble de protection comprenant une plaque résistante à la pénétration, un bâti de support et des moyens de fixation à la demande au sommet de la base. La plaque comprend une couche en acier AR500, une couche en résine ionomère Surlyn®, une couche en céramique opaque à 98% de silicate d'aluminium, une couche en résine ionomère Surlyn®, et une couche en fibre aramide Kevlar®. WO 2009/035637 relates to a central motorway separator comprising a pre-existing concrete base with sloping side faces and a protective sub-assembly comprising a penetration resistant plate, a support frame and means of on-demand attachment to the top of the road. based. The plate comprises an AR500 steel layer, a Surlyn® ionomer resin layer, a 98% aluminum silicate opaque ceramic layer, a Surlyn® ionomer resin layer, and a Kevlar® aramid fiber layer.

Récemment, de graves évènements dans des lieux accueillant du public ont amené la Demanderesse à chercher à mieux protéger les personnes. En effet, la combinaison arme à feu d'épaule, de type fusil d'assaut, et explosif à forte charge dans un attentat multiple s'avère meurtrière. Les charges peuvent atteindre plusieurs dizaines de kilos d'équivalent TNT, par exemple dans des valises ou des sacs de voyage de grand volume. Au début se produit un mitraillage à l'arme à feu, puis une ou plusieurs explosions.Recently, serious events in places open to the public have led the Applicant to seek to better protect people. Indeed, the combination of long gun, assault rifle type, and high charge explosive in a multiple attack is deadly. The loads can reach several tens of kilos of TNT equivalent, for example in suitcases or large-volume travel bags. At the beginning, there is a strafing with the firearm, then one or more explosions.

Des gilets pare-balles ne peuvent pas être portés par l'ensemble du public et ne protègent pas contre l'effet de souffle de l'explosion.Body armor cannot be worn by the general public and will not protect against the blast effect of the explosion.

Par ailleurs, la Demanderesse a procédé à l'analyse des lieux visés par de tels évènements. Il s'agit de lieux susceptibles d'accueillir une forte densité de personnes, tant en mouvement qu'à l'arrêt, notamment gare, aéroport, centre commercial, lieu de culte, salle de spectacle, stade, halle d'exposition, musée, hôtel, voie publique, etc. Le sol est en général constitué d'une dalle en béton. L'espace peut être cloisonné par des séparations légères, telles que parois de verre, panneaux de cloison mobiles, etc.. Les séparations légères sont susceptibles de s'effondrer, d'être transpercées par les projectiles ou encore de se fragmenter en multipliant ainsi les projectiles.Furthermore, the Applicant has carried out an analysis of the places targeted by such events. These are places likely to accommodate a high density of people, both moving and stationary, in particular train station, airport, shopping center, place of worship, performance hall, stadium, exhibition hall, museum , hotel, public road, etc. The floor is generally made of a concrete slab. The space can be partitioned off by light partitions, such as glass walls, movable partition panels, etc. Light partitions are liable to collapse, to be pierced by projectiles or even to fragment by multiplying in this way. the projectiles.

On entend ici par projectiles, les morceaux de matière présentant un danger pour les personnes. Les projectiles comprennent les balles issues d'armes à feu, les morceaux issus de ricochets de balles et comprenant de la matière de la balle et/ou de la matière de l'objet sur lequel la balle a ricoché, les éclats issus d'explosion directement par exemple des fragments du contenant de l'explosif ou des pièces métalliques ajoutées au voisinage de l'explosif ou indirectement par exemple des éclats de verre.The term “projectiles” is understood here to mean pieces of material presenting a danger to people. Projectiles include bullets from firearms, pieces from ricochets from bullets and comprising material from the bullet and / or material from the object on which the bullet ricocheted, shards from the explosion directly for example fragments of the explosive container or metal parts added to the vicinity explosive or indirectly, for example, shards of glass.

Une contrainte s'avère être de conserver l'aptitude du lieu à permettre un flux de personnes. Une autre contrainte est de conserver l'aptitude du lieu au stationnement de personnes. Une contrainte supplémentaire est d'améliorer la protection dans une infrastructure existante, notamment de génie civil. Une contrainte est aussi la conservation du modèle économique du lieu, par exemple les boutiques d'aéroport ou de gare, les stands, les bars ou autres commodités dans une halle. La visibilité et l'accessibilité sont à conserver. Une contrainte est aussi de venir rapidement améliorer la protection.One constraint turns out to be to preserve the aptitude of the place to allow a flow of people. Another constraint is to maintain the suitability of the place for parking people. An additional constraint is to improve the protection in an existing infrastructure, in particular civil engineering. A constraint is also the conservation of the economic model of the place, for example airport or station shops, stands, bars or other amenities in a hall. Visibility and accessibility must be maintained. A constraint is also to come quickly to improve protection.

Le dispositif de protection anti-souffle, anti-fragment, anti-balle, anti-ricochet et anti-véhicule, biface, pour lieu recevant du public, comprend :

  • un panneau sandwich comprenant deux couches extérieures réalisées en matériau de faible dureté, au moins deux couches intérieures réalisées en matériau de dureté élevée, chacune en contact avec une desdites couches extérieures, et au moins une couche intérieure réalisée en matériau de faible dureté et en contact avec des couches intérieures réalisées en matériau de dureté élevée, et
  • deux merlons disposés chacun de biais par rapport au panneau sandwich et fixés au panneau sandwich, pourvus d'un bord en contact avec le substrat ou un sol, et formant déviateurs de souffle.
The anti-blast, anti-fragment, anti-bullet, anti-ricochet and anti-vehicle protection device, biface, for places open to the public, includes:
  • a sandwich panel comprising two outer layers made of low hardness material, at least two inner layers made of high hardness material, each in contact with one of said outer layers, and at least one inner layer made of low hardness material and in contact with inner layers made of high hardness material, and
  • two merlons each arranged at an angle with respect to the sandwich panel and fixed to the sandwich panel, provided with an edge in contact with the substrate or a ground, and forming blast deflectors.

Ainsi, le panneau sandwich est susceptible d'arrêter les projectiles, courants et même perforants, d'armes à feu portatives et les projectiles d'explosion, est non ricochant jusqu'à des angles d'incidence faibles par exemple 10°, absorbe une partie de l'énergie du souffle de l'explosion et dévie la trajectoire du souffle. L'absorption est aussi assurée par la déformation éventuelle du merlon du panneau sandwich. La déviation du souffle est assurée par le merlon et par le panneau sandwich.Thus, the sandwich panel is capable of stopping projectiles, currents and even armor-piercing, portable firearms and explosion projectiles, is non-ricocheting down to low angles of incidence, for example 10 °, absorbs a part of the blast energy from the explosion and deflects the path of the blast. Absorption is also ensured by the possible deformation of the fence of the sandwich panel. The deflection of the breath is ensured by the fence and by the sandwich panel.

En outre, la Demanderesse, au cours de ses travaux, s'est aperçu que les trajectoires et les vitesses d'une balle d'arme à feu, d'un éclat projeté par une explosion et du souffle sont différentes nécessitant un traitement particulier. Une balle d'arme longue également dénommée arme d'épaule est animée d'une vitesse élevée de l'ordre de 800 à 900 m.s-1 et présente donc une trajectoire tendue assimilable à une droite aux portées usuelles et située à hauteur du tronc des personnes, soit 1 à 1,5 mètres de hauteur par rapport au sol. Les éclats d'explosion peuvent présenter des vitesses sur une très large plage allant de valeurs au-delà de 1000 m.s-1, supérieures aux balles d'armes longues, à des valeurs en dessous de 300 m.s-1, inférieures aux balles d'armes de poing, en fonction de leur densité, de leur rapport surface/volume et de leur forme. Certains éclats sont donc dangereux en perforation tandis que d'autres sont sujets à ricochet. La répartition spatiale des éclats d'explosion est sensiblement isotrope. Le souffle se propage dans toutes les directions libres mais avec une prépondérance à proximité du sol. Ceci est vérifié pour une explosion ne traversant pas le sol mais reste globalement valable pour une explosion endommageant fortement le sol, voire le traversant dans le cas d'un sol d'étage d'une construction. Le dispositif de protection traite de l'ensemble de ces situations.In addition, the Applicant, during its work, has noticed that the trajectories and speeds of a bullet from a firearm, of a burst projected by an explosion and of the blast are different, requiring special treatment. A long weapon bullet, also called a long gun, is driven at a high speed of the order of 800 to 900 ms -1 and therefore has a taut trajectory similar to a straight line with usual spans and located at the height of the body of people, ie 1 to 1.5 meters above the ground. Explosion shards can exhibit speeds over a very wide range, from values beyond 1000 ms -1 , higher than long gun bullets, to values below 300 ms -1 , lower than bullets. handguns, depending on their density, surface / volume ratio and shape. Some shards are therefore dangerous in perforation while others are subject to ricochet. The spatial distribution of explosion fragments is substantially isotropic. The breath propagates in all free directions but with a preponderance near the ground. This is verified for an explosion that does not pass through the ground but remains globally valid for an explosion severely damaging the ground, or even passing through it in the case of a floor of a building floor. The protection system deals with all of these situations.

En outre, le dispositif de protection constitue un obstacle significatif contre les véhicules, même après un éventuel basculement latéral. Le dispositif de protection présente une masse comprise entre 500 et 1000 kg. De par sa masse et ses dimensions, le dispositif de protection est difficile à pousser et contribue au freinage ou à l'arrêt d'un véhicule l'ayant rencontré.In addition, the protective device constitutes a significant obstacle against vehicles, even after a possible lateral tilt. The protective device has a mass of between 500 and 1000 kg. Due to its mass and dimensions, the protection device is difficult to push and contributes to the braking or stopping of a vehicle that has encountered it.

Par ailleurs, l'emprise au sol du dispositif de protection est faible et sa largeur impacte peu les circulations de personnes. Enfin, la Demanderesse s'est aperçu que l'augmentation des charges explosives produisait des dégâts ne croissant pas dans la même proportion dans la mesure où était dépassée la résistance du sol. Ainsi, la perforation d'une dalle de béton consomme une partie significative de l'énergie de l'explosion. L'efficacité du dispositif de protection est susceptible d'être bonne pour de telles charges.In addition, the footprint of the protective device is small and its width has little impact on the movement of people. Finally, the Applicant noticed that the increase in explosive charges produced damage that did not increase in the same proportion to the extent that the resistance of the ground was exceeded. Thus, the perforation of a concrete slab consumes a significant part of the energy of the explosion. The efficiency of the protective device is likely to be good for such loads.

Le dispositif de protection est statique tout en pouvant être déplacé par un engin de manutention courant. Le dispositif de protection peut, en variante, être pourvu de roues, démontables ou escamotables. Le dispositif de protection est passif. Le dispositif de protection est conçu pour être fixé au sol, par scellement, ancrage, etc., éventuellement de manière démontable.The protection device is static while being able to be moved by a common handling machine. The protection device may, as a variant, be provided with wheels, which can be dismantled or retracted. The protection device is passive. The protection device is designed to be fixed to the ground, by sealing, anchoring, etc., possibly in a removable manner.

Le dispositif de protection peut également ne pas être fixé au sol, simplement posé et associé à d'autres dispositifs similaires et reliés entre eux par une liaison au sol pouvant être souple ou rigide de type barre ou câble, ou un seul dispositif peut être fixé par ces liaisons à des points fixes.The protection device may also not be fixed to the ground, simply placed and associated with other similar devices and linked together by a ground connection which may be flexible or rigid of the bar or cable type, or a single device may be fixed. by these links to fixed points.

Le dispositif assure une protection biface.The device provides two-sided protection.

Le dispositif de protection peut également freiner ou arrêter des véhicules en cas de choc. En effet, une percussion d'un véhicule dans le plan principal du dispositif crée un freinage par augmentation de la masse à déplacer et frottement au sol. Une percussion d'un véhicule perpendiculairement au plan principal du dispositif de protection génère en plus une absorption d'énergie par déformation du dispositif de protection et un frottement au sol supplémentaire.The protective device can also brake or stop vehicles in the event of an impact. Indeed, a percussion of a vehicle in the main plane of the device creates braking by increasing the mass to be moved and friction on the ground. A percussion of a vehicle perpendicular to the main plane of the protective device also generates energy absorption by deformation of the protective device and additional friction on the ground.

Les couches extérieures de dureté faible évitent la formation d'éclats supplémentaires, diminuent les ricochets, en particulier de projectiles lents et légers, et dissipent de l'énergie vibratoire des couches dures. Les couches intérieures de dureté élevée absorbent l'énergie cinétique des projectiles, notamment rapides, transmettent aux couches adjacentes une partie de l'énergie reçue, arrêtent une partie des projectiles entrant et une partie des projectiles sortant ayant déjà traversé d'autres couches. Les notions de vitesse lente/rapide sont relatives. On peut considérer qu'une balle d'arme longue à canon rayé animée d'une vitesse de l'ordre de 700 à 1000 m.s-1 est rapide et qu'une balle d'arme de poing ou d'arme à canon lisse animée d'une vitesse de l'ordre de 300 à 400 m.s-1 est lente. Les éclats d'explosion sont en général encore moins rapides et très sujets à ricochet.The low hardness outer layers prevent additional splinter formation, reduce ricochets, especially from slow and light projectiles, and dissipate vibrational energy from hard layers. The interior layers of high hardness absorb the kinetic energy of projectiles, in particular fast projectiles, transmit part of the received energy to adjacent layers, stop part of the incoming projectiles and part of the outgoing projectiles that have already passed through other layers. The notions of slow / fast speed are relative. We can consider that a long rifled gun bullet animated with a speed of the order of 700 to 1000 ms -1 is fast and that a handgun or smoothbore bullet animated with a speed of the order of 300 to 400 ms -1 is slow. Explosion shards are generally even slower and very prone to ricochet.

Après de nombreux essais, avec une vaste gamme de projectiles sous des incidences variées, la Demanderesse a mis au point un multicouche de type très tendre-dur-tendre-très dur offrant des performances anti-perforation, anti-ricochet et anti-souffle remarquables dans une épaisseur contenue et une masse acceptable par la plupart des infrastructures.After numerous tests, with a wide range of projectiles under various incidences, the Applicant has developed a multilayer of the very soft-hard-soft-very hard type offering remarkable anti-perforation, anti-ricochet and anti-blast performance. in a contained thickness and a mass acceptable by most infrastructures.

Le dispositif de protection à panneau balistique a pour but de réduire le nombre de victimes et la gravité des blessures lors d'un attentat survenant dans un lieu accueillant du public. Le panneau balistique permet d'intercepter des projectiles et d'offrir un abri aux personnes exposées. Le panneau balistique présente de manière symétrique des propriétés de stabilité propre, des propriétés pare-éclats, des propriétés déviatrices de l'effet de souffle, et des propriétés d'absorption d'énergie par déformation.The purpose of the ballistic panel protection device is to reduce the number of victims and the severity of injuries during an attack in a place open to the public. The ballistic panel makes it possible to intercept projectiles and offer shelter to exposed persons. The ballistic panel symmetrically exhibits inherent stability properties, shatterproof properties, blast deflection properties, and deformation energy absorption properties.

Comme illustré sur les figures, le dispositif de protection est symétrique par rapport à un plan longitudinal généralement vertical. Le plan longitudinal est noté X-Z. Le dispositif de protection est symétrique par rapport à un plan transversal généralement vertical et perpendiculaire au plan longitudinal. Le plan transversal est noté Y-Z. Le dispositif de protection 1 peut présenter une largeur comprise entre 60 et 100 cm, selon l'axe Y. Le dispositif de protection 1 est biface à faces identiques en termes de protection.As illustrated in the figures, the protection device is symmetrical with respect to a generally vertical longitudinal plane. The longitudinal plane is denoted X-Z. The protection device is symmetrical with respect to a generally vertical transverse plane and perpendicular to the longitudinal plane. The transverse plane is denoted Y-Z. The protection device 1 can have a width of between 60 and 100 cm, along the Y axis. The protection device 1 is two-sided with identical faces in terms of protection.

Le dispositif de protection 1 comprend un panneau sandwich 2 de forme générale parallélépipédique. La longueur selon l'axe X est supérieure à la hauteur selon l'axe Z. La hauteur selon l'axe Z est supérieure à l'épaisseur selon l'axe Y, d'un facteur d'au moins 5. L'épaisseur du panneau sandwich 2 peut être comprise entre 8 et 20 cm, préférablement entre 12 et 17 cm. Dans une variante, le panneau sandwich 2 peut présenter en coupe transversale une section trapézoïdale à base située près du sol. Le panneau sandwich 2 est formé sur la hauteur et la longueur du dispositif de protection 1.The protection device 1 comprises a sandwich panel 2 of generally parallelepipedal shape. The length along the X axis is greater than the height along the Z axis. The height along the Z axis is greater than the thickness along the Y axis, by a factor of at least 5. The thickness of the sandwich panel 2 may be between 8 and 20 cm, preferably between 12 and 17 cm. In a variant, the sandwich panel 2 may have in cross section a trapezoidal section with a base located near the ground. The sandwich panel 2 is formed along the height and length of the protective device 1.

Le dispositif de protection 1 comprend deux merlons 3 déviateurs de souffle. Les merlons 3 sont disposés sur la longueur du dispositif de protection 1. Les merlons 3 sont formés sur une partie de la hauteur du dispositif de protection 1 en partant du bas. Les merlons 3 présentent, ici, une section en triangle rectangle en coupe dans le plan transversal. La section des merlons 3 est constante. Les merlons 3 comprennent des extrémités fermées. Les merlons 3 comprennent une enveloppe en tôle d'acier. L'enveloppe peut être pliée et soudée. L'enveloppe peut former un caisson.The protection device 1 comprises two merlons 3 blast deflectors. The merlons 3 are arranged along the length of the protection device 1. The merlons 3 are formed over part of the height of the protection device 1 starting from the bottom. The merlons 3 present, here, a section in a right-angled triangle in section in the transverse plane. The section of merlons 3 is constant. Merlons 3 include closed ends. Merlons 3 include a sheet steel casing. The envelope can be folded and welded. The envelope can form a box.

Les deux merlons 3 d'un dispositif de protection 1 peuvent être formés à partir d'une tôle unique ou d'un ensemble unique. Ledit ensemble unique peut comprendre au moins une couche de faible dureté et au moins une couche de haute dureté. Dans ce cas, la tôle unique peut former les deux merlons 3 et une surface supportant le panneau sandwich 2. Une tôle inférieure d'épaisseur plus faible peut former la paroi inférieure en appui sur le sol. Entre les merlons 3 peut être installé au moins parmi : un rebord de la tôle d'un merlon, un rebord de chaque tôle d'un merlon, un rebord de la tôle unique, un rebord de l'ensemble unique, une région inférieure du panneau sandwich 2 de même structure qu'une région supérieure du panneau sandwich 2, une région inférieure du panneau sandwich 2 de structure moins épaisse qu'une région supérieure du panneau sandwich 2, notamment une prolongation vers le bas d'une couche de dureté élevée.The two merlons 3 of a protection device 1 can be formed from a single sheet or from a single assembly. Said single assembly may include at least one low hardness layer and at least one high hardness layer. In this case, the single sheet can form the two merlons 3 and a surface supporting the sandwich panel 2. A lower sheet of lower thickness can form the lower wall resting on the ground. Between the merlons 3 can be installed at least among: a rim of the sheet of a barrier, a rim of each sheet of a barrier, a rim of the single sheet, a rim of the single assembly, a lower region of the sandwich panel 2 of the same structure as an upper region of the sandwich panel 2, a lower region of the sandwich panel 2 of less thickness than an upper region of the sandwich panel 2, in particular a downward extension of a layer of high hardness .

Un projectile traversant la paroi extérieure d'un merlon présente une probabilité élevée d'être sur une trajectoire descendante vers sol et de ricochet à l'intérieur du dispositif de protection 1, soit sur le sol ou la paroi inférieure vers le merlon 3 opposé, soit sur le merlon 3 opposé vers le sol ou la paroi inférieure. Le ricochet à l'intérieur du dispositif de protection 1 est souhaitable car l'énergie du projectile est nettement réduite par un tel ricochet. En ce sens, l'épaisseur des couches dures peut être plus faible à la hauteur des merlons 3 qu'au-dessus des merlons 3.A projectile passing through the outer wall of a fence has a high probability of being on a downward trajectory towards the ground and of ricochet inside the protection device 1, either on the ground or the lower wall towards the opposite fence 3, either on the fence 3 opposite to the ground or the lower wall. The ricochet inside the protection device 1 is desirable because the energy of the projectile is markedly reduced by such a ricochet. In this sense, the thickness of the hard layers can be lower at the height of the 3 merlons than above the 3 merlons.

Les merlons 3 présentent en sous face orientée vers le sol une ou deux rainures 4 longitudinales ouvertes aux extrémités pour la manutention du dispositif de protection 1 par un engin de manutention à fourches, tel que transpalette, chariot élévateur, grue, etc. On évite la présence de rainures transversales susceptibles de transmettre l'effet de souffle. Le dispositif de protection 1 repose au sol par les merlons 3. La surface inférieure 5 du dispositif de protection 1 est plane pour offrir un contact avec un sol plan sans solution de continuité selon l'axe transversal Y. Une propagation d'un effet de souffle est évitée. Les merlons 3 peuvent présenter une hauteur de 30 à 50 cm.The merlons 3 have on the underside oriented towards the ground one or two longitudinal grooves 4 open at the ends for the handling of the protection device 1 by a handling machine with forks, such as a pallet truck, forklift, crane, etc. The presence of transverse grooves capable of transmitting the blast effect is avoided. The protection device 1 rests on the ground by the merlons 3. The lower surface 5 of the protection device 1 is flat to provide contact with a flat ground without any solution of continuity along the axis. transverse Y. A propagation of a blast effect is avoided. The merlons 3 can have a height of 30 to 50 cm.

Chaque merlon 3 comprend une paroi oblique 6. Vue en coupe transversale, la paroi oblique 6 s'étend d'une région distale du plan de symétrie et inférieure à une région proximale du plan de symétrie et supérieure. La paroi oblique 6 est droite dans les modes de réalisation illustrés. La paroi oblique 6 est concave dans d'autres modes de réalisation. Chaque merlon 3 peut comprendre une paroi inférieure ou sous face.Each merlon 3 comprises an oblique wall 6. Viewed in cross section, the oblique wall 6 extends from a region distal to the plane of symmetry and below to a region proximal to the plane of symmetry and above. The oblique wall 6 is straight in the illustrated embodiments. The oblique wall 6 is concave in other embodiments. Each merlon 3 can include a lower wall or an underside.

La paroi oblique 6 présente un angle compris entre 30 et 60° avec le plan X-Z. Une inclinaison de 45° est préférée pour une stabilité latérale du dispositif de protection, une compatibilité avec des sièges, un accroissement de plus de 40% de l'épaisseur de l'obstacle pour un projectile à trajectoire horizontale, et un encombrement restreint. La paroi oblique 6 peut être plane. La paroi oblique 6 peut comprendre une tôle d'épaisseur comprise entre 3 et 10 mm. Les merlons 3 sont efficaces pour dévier le souffle d'une explosion et participer à la dissiper.The oblique wall 6 has an angle of between 30 and 60 ° with the X-Z plane. An inclination of 45 ° is preferred for lateral stability of the protection device, compatibility with seats, an increase of more than 40% in the thickness of the obstacle for a projectile with a horizontal trajectory, and a small footprint. The oblique wall 6 can be flat. The oblique wall 6 can comprise a sheet of thickness between 3 and 10 mm. Merlons 3 are effective for deflecting the blast of an explosion and helping to dispel it.

La paroi oblique 6 peut comprendre, en outre, au moins une couche de matériau de faible dureté analogue au matériau de faible dureté du panneau sandwich 2, disposée à l'extérieur et/ou à l'intérieur de la paroi oblique 6. Dans une variante, la paroi oblique 6 peut être formée en continuité de la moitié du panneau sandwich 2. La paroi oblique 6 peut être constituée de manière identique à un ensemble latéral du panneau sandwich 2 dans le sens de l'épaisseur. Ainsi, le panneau sandwich 2 se sépare vers le bas en Y inversé.The oblique wall 6 may further comprise at least one layer of low hardness material similar to the low hardness material of the sandwich panel 2, arranged outside and / or inside the oblique wall 6. In a As a variant, the oblique wall 6 can be formed in continuity with half of the sandwich panel 2. The oblique wall 6 can be formed in an identical manner to a lateral assembly of the sandwich panel 2 in the direction of the thickness. Thus, the sandwich panel 2 separates downwards in an inverted Y.

Les merlons 3 sont reliés par des entretoises 7. Les entretoises 7 peuvent être au nombre de trois pour une longueur d'un mètre environ, de quatre pour une longueur de 1,20 m à 1,80 m et de cinq au-delà. Les entretoises 7 disposées en extrémité des merlons 3 forment une paroi d'extrémité. Les parois d'extrémité sont fermées en ce sens qu'un projectile de dimension dangereuse, par exemple supérieure à 1 ou 2 mm, ne peut pas y trouver de passage. Les entretoises 7 présentent un contour de forme générale trapézoïdale avec un sommet correspondant à l'épaisseur du panneau sandwich 2, des côtés correspondant aux parois 6 des merlons 3 et une base concave en raison de la rainure 4. Les entretoises 7 peuvent présenter une épaisseur comprise entre 10 et 20 mm.The merlons 3 are connected by spacers 7. The spacers 7 may be three in number for a length of approximately one meter, four for a length of 1.20 m to 1.80 m and five beyond. The spacers 7 arranged at the end of the merlons 3 form an end wall. The end walls are closed in the sense that a projectile of dangerous size, for example greater than 1 or 2 mm, cannot find a way through them. The spacers 7 have an outline of generally trapezoidal shape with an apex corresponding to the thickness of the sandwich panel 2, sides corresponding to the walls 6 of the merlons 3 and a concave base due to the groove 4. The spacers 7 may have a thickness between 10 and 20 mm.

Avantageusement, les entretoises 7 disposées en extrémité sont soudées aux parois 6 des merlons 3. La ou les entretoises 7 disposées à l'intérieur sont soudées aux parois 6 des merlons 3.Advantageously, the spacers 7 disposed at the end are welded to the walls 6 of the merlons 3. The spacers 7 disposed inside are welded to the walls 6 of the merlons 3.

Le dispositif de protection 1 comprend un châssis 8. Le châssis 8 comprend un cadre mécano soudé. Le châssis 8 sépare le panneau sandwich 2 en deux ensembles latéraux 20, 21. Le châssis 8 supporte le panneau sandwich 2 et est supporté par les merlons 3. Le châssis 8, le panneau sandwich 2 et les merlons 3 sont fixés ensemble par soudure. Le châssis 8 peut supporter une ou plusieurs couches dures disposées entre les merlons 3, notamment verticalement.The protection device 1 comprises a frame 8. The frame 8 comprises a mechanically welded frame. The frame 8 separates the sandwich panel 2 into two side assemblies 20, 21. The frame 8 supports the sandwich panel 2 and is supported by the merlons 3. The frame 8, the sandwich panel 2 and the merlons 3 are fixed together by welding. The frame 8 can support one or more hard layers arranged between the merlons 3, in particular vertically.

Le bord supérieur du dispositif de protection 1 peut être recouvert par une tôle cachant la tranche du châssis 8 et du panneau sandwich 2. Les bords latéraux verticaux du dispositif de protection 1 peuvent être recouverts par une tôle cachant la tranche du châssis 8 et du panneau sandwich 2. La ou lesdites tôles évitent que des projectiles issus de l'espace 22 n'en ressortent par le chant ou la tranche du dispositif de protection 1.The upper edge of the protection device 1 can be covered by a sheet hiding the edge of the frame 8 and of the sandwich panel 2. The vertical side edges of the protection device 1 can be covered by a sheet hiding the edge of the frame 8 and of the panel. sandwich 2. Said sheet or sheets prevent projectiles from the space 22 from coming out through the edge or the edge of the protection device 1.

Dans le mode de réalisation représenté sur les figures 4 et 5, le panneau sandwich 2 comprend huit couches 201, 202, 203, 204, 211, 212, 213, 214 réparties en lesdits ensembles latéraux 20, 21 de quatre couches, séparés par un espace 22. Chaque ensemble latéral 20, 21 comprend, de l'extérieur vers l'intérieur du panneau sandwich 2, une première couche 201, 211 réalisée en matériau de faible dureté, une deuxième couche 202, 212 réalisée en matériau de dureté élevée, une troisième couche 203, 213 réalisée en matériau de faible dureté, une quatrième couche 204, 214 réalisée en matériau de dureté élevée.

L'espace 22 entre les ensembles latéraux 20, 21 est de largeur supérieure à l'épaisseur des deux ensembles latéraux 20, 21. Ainsi, un projectile ayant traversé un premier desdits ensembles latéraux 20, 21 peut ricocher contre le deuxième desdits ensembles latéraux 20, 21 et rester dans ledit espace 22. Plus un projectile est lent plus il a tendance à ricocher à angle d'incidence égal.The space 22 between the lateral assemblies 20, 21 is of a width greater than the thickness of the two lateral assemblies 20, 21. Thus, a projectile having passed through a first of said lateral assemblies 20, 21 can ricochet against the second of said lateral assemblies 20. , 21 and remain in said space 22. The slower a projectile the more it tends to ricochet at an equal angle of incidence.

De façon plus générale, le panneau sandwich 2 peut comprendre deux couches extérieures 201, 211 réalisées en matériau de faible dureté, au moins deux couches intérieures 202, 212 réalisées en matériau de dureté élevée, chacune en contact avec une desdites couches extérieures 201, 211, et au moins une couche intérieure réalisée en matériau de faible dureté et en contact avec des couches intérieures réalisées en matériau de dureté élevée.More generally, the sandwich panel 2 can comprise two outer layers 201, 211 made of low hardness material, at least two inner layers 202, 212 made of high hardness material, each in contact with one of said outer layers 201, 211 , and at least one inner layer made of low hardness material and in contact with inner layers made of high hardness material.

Dans le mode de réalisation représenté, le panneau sandwich 2 présente une hauteur comprise entre 100 et 170 cm, une largeur comprise entre 100 et 250 cm, et préférablement une forme de parallélépipède rectangle sur chant. Le bord supérieur 23 (chant) du panneau sandwich 2 peut être arrondi.In the embodiment shown, the sandwich panel 2 has a height of between 100 and 170 cm, a width of between 100 and 250 cm, and preferably the shape of a rectangular parallelepiped on the edge. The upper edge 23 (edge) of the sandwich panel 2 can be rounded.

Le panneau sandwich 2 est résistant aux calibres usuels : 9 mm Parabellum, 5,56 mm, 7,62 mm, 308 Winchester, 338 LP, 12,7 mm à balle ordinaire, en ce sens que le projectile ne traverse pas le panneau sandwich 2 à 50 m de distance de tir. En outre, y compris en 9 mm Parabellum, le projectile ne ricoche pas jusqu'à un angle d'incidence de 10°. Plus l'angle d'incidence est faible, plus le risque de ricochet est élevé et moins le projectile est pénétrant. En effet, un projectile tiré sous incidence de i° est confronté sur sa trajectoire à une épaisseur de paroi Et égale à l'épaisseur E de paroi prise selon l'axe Y divisée par cosinus i°, soit par exemple Et = 2E pour i = 30°.The sandwich panel 2 is resistant to the usual calibers: 9 mm Parabellum, 5.56 mm, 7.62 mm, 308 Winchester, 338 LP, 12.7 mm with ordinary bullet, in the sense that the projectile does not pass through the sandwich panel 2 to 50 m shooting distance. In addition, including in 9 mm Parabellum, the projectile does not ricochet up to an angle of incidence of 10 °. The lower the angle of incidence, the greater the risk of ricochet and the less penetrating the projectile. Indeed, a projectile fired under incidence of i ° is confronted on its trajectory with a wall thickness Et equal to the wall thickness E taken along the Y axis divided by cosine i °, ie for example Et = 2E for i = 30 °.

La résistance à la pénétration de projectiles à haute vitesse est testée à incidence de 90°. De manière générale, il est considéré que les calibres 12,7 mm et au-dessus sont trop lourds et encombrants pour être aisément utilisés lors d'opérations illégales visant le public. Le dispositif de protection 1 est capable de résister aux balles ordinaires de 12,7 mm. Pour des circonstances à haute dangerosité, il est apte à résister aux balles perforantes de 12,7 mm ou aux balles de 14,5 mm en remplaçant l'acier Hardox 400 par un acier de dureté supérieure, notamment un acier balistique, par exemple Ramor® ou équivalent en dureté, ou en augmentant l'épaisseur de la ou des couche d'acier située à l'intérieur, ou en installant une couche d'acier interne supplémentaire éventuellement associée à une couche supplémentaire de matériau de faible dureté.The resistance to penetration of high speed projectiles is tested at 90 ° incidence. Generally speaking, calibers 12.7mm and above are considered too heavy and bulky to be readily used in illegal operations targeting the public. The protective device 1 is able to withstand ordinary 12.7mm bullets. For highly dangerous circumstances, it is able to withstand 12.7 mm perforating bullets or 14.5 mm bullets by replacing Hardox 400 steel with a steel of higher hardness, in particular a ballistic steel, for example Ramor ® or equivalent in hardness, or by increasing the thickness of the steel layer (s) located inside, or by installing an additional internal steel layer possibly associated with an additional layer of low hardness material.

Dans le mode de réalisation représenté sur les figures 4 et 5, le dispositif de protection 1 comprend des sièges 9 supportés par des barres 10 reliées aux merlons 3. Les sièges 9 sont en partie situés au-dessus des merlons 3. L'encombrement est réduit et la stabilité latérale élevée.In the embodiment shown in figures 4 and 5 , the protection device 1 comprises seats 9 supported by bars 10 connected to the merlons 3. The seats 9 are partly located above the merlons 3. The size is reduced and the lateral stability is high.

Ainsi, le dispositif de protection 1 dévie et dissipe au moins en partie le souffle d'une explosion, arrête les fragments et éclats, notamment de grenade, tout en évitant les ricochets à des incidences faibles, arrête les balles des armes portatives courantes, tout en évitant les ricochets jusqu'à des incidences faibles et ce de manière symétrique. Le souffle d'explosion génère des oscillations amorties au sein de la structure du panneau sandwich. Il y a dissipation de l'énergie du souffle d'explosion.Thus, the protection device 1 deflects and at least partially dissipates the blast of an explosion, stops fragments and shards, in particular of grenades, while avoiding ricochets at low incidences, stops bullets from common portable weapons, all avoiding ricochets up to low incidences and this in a symmetrical manner. The explosion blast generates damped oscillations within the structure of the sandwich panel. There is dissipation of the energy of the blast of explosion.

Dans un mode de réalisation, le dispositif de protection 1 comprend au moins une assise de siège disposée sur une face du panneau sandwich 2, au moins en partie au-dessus du merlon 3.In one embodiment, the protection device 1 comprises at least one seat cushion arranged on one face of the sandwich panel 2, at least partly above the fence 3.

Dans un mode de réalisation, un ensemble comprend une pluralité de dispositifs de protection 1 présentant une pluralité d'orientations.In one embodiment, an assembly comprises a plurality of protection devices 1 having a plurality of orientations.
