Description

Le domaine technique de l'invention est celui des dispositifs de fixation des écrans pare-éclats sur les parois internes des structures blindées.The technical field of the invention is that devices fixing the splinter screens on the internal walls of the shielded structures.

Les structures blindées, telles que des structures fixes (bâtiments ou casemates) ou les véhicules blindés, sont susceptibles de subir des agressions balistiques suffisamment violentes pour endommager les parois de la structure et générer des éclats de matériaux vers l'intérieur ce qui peut être préjudiciable aux personnels se trouvant à l'intérieur.Armored structures, such as fixed structures (buildings or bunkers) or armored vehicles, are likely to suffer ballistic aggressions sufficiently violent to damage the walls of the structure and to generate fragments of materials inwards which can be detrimental to the staff inside.

Pour parer à ce risque, il est connu de doubler l'intérieur des parois d'une structure blindée d'un écran dit pare-éclats. Ce type de pare-éclats comporte généralement un matériau composite indéchirable et souple.To counter this risk, it is known to double the inside of the walls of an armored structure of a screen said splinterguard. This type of splinterguard generally comprises a composite material tear-proof and flexible.

Ce type d'écran est généralement fixé aux parois par vissage. Les têtes des vis associées à des rondelles d'appui plaquent le pare-éclats contre la paroi. L'inconvénient majeur d'une telle solution de fixation est que, durant une agression, l'écran peut se décoller de la paroi à l'endroit de la génération d'éclats et soulever la rondelle d'appui par un bord, exerçant ainsi, juste sous la tête de vis, un couple et un effort de cisaillement capables de rompre cette tête et de la projeter dangereusement vers l'équipage avec la rondelle l'accompagnant. Dans le cas où l'écran glisse le long de la paroi, la tête de vis risque d'être cisaillée puis également projetée.This type of screen is generally fixed to the walls by screwing. The heads of the screws associated with bearing washers press the splinterguard against the wall. The major disadvantage of such a fixing solution is that, during an attack, the screen can peel off the wall at the point of generation of chips and lift the support washer by an edge, thus exerting just under the head of the screw, a couple and a shearing force capable of breaking this head and throwing it dangerously towards the crew with the puck accompanying it. In the case where the screen slides along the wall, the screw head may be sheared and then projected.

L'invention propose de résoudre ce problème de projection d'éléments dangereux.The invention proposes to solve this problem of projection of dangerous elements.

Avantageusement l'invention propose également de résoudre le problème de cisaillement de la tête de vis.Advantageously, the invention also proposes to solve the problem of shearing the screw head.

Ainsi, l'invention a pour objet un dispositif de fixation destiné à assurer la fixation d'un pare-éclats sur une face interne d'une paroi d'une structure blindée, dispositif caractérisé en ce qu'il comporte :

  • une embase comportant une collerette destinée à être placée dans un lamage de la paroi, sous une première face du pare-éclats, embase comportant au moins un perçage destiné à être traversé par une vis solidaire de la paroi, embase comportant également une jupe s'étendant sensiblement perpendiculairement à la collerette et destinée à traverser un trou du pare-éclats et à abriter au moins partiellement la tête de la vis,
  • un couvercle comportant une portée annulaire destinée à prendre appui sur une seconde face du pare-éclats, couvercle comprenant des moyens permettant d'assurer sa solidarisation avec la jupe et destinés à assurer le serrage du pare-éclats.
Thus, the subject of the invention is a fixing device intended to ensure the attachment of a splinterguard on one side internal wall of a shielded structure, characterized in that it comprises:
  • a base comprising a collar intended to be placed in a countersink of the wall, under a first face of the splinterguard, base comprising at least one bore to be traversed by a screw secured to the wall, base also comprising a skirt s' extending substantially perpendicularly to the flange and intended to pass through a hole of the splinter guard and at least partially to house the head of the screw,
  • a cover comprising an annular bearing intended to bear on a second face of the splinterguard, cover comprising means for securing it to the skirt and intended to ensure the clamping of the splinterguard.

Selon un mode de réalisation, les moyens assurant la solidarisation du couvercle avec la jupe pourront comprendre un taraudage du couvercle engagé sur un filetage de la jupe.According to one embodiment, the means ensuring the fastening of the cover with the skirt may comprise a tapping of the cover engaged on a thread of the skirt.

Selon un autre mode de réalisation, les moyens assurant la solidarisation du couvercle avec la jupe pourront comprennent un filetage du couvercle engagé dans un taraudage de la jupe.According to another embodiment, the means ensuring the fastening of the cover with the skirt may comprise a thread of the cover engaged in a tapping of the skirt.

Avantageusement, le couvercle comporte un profil permettant son serrage.Advantageously, the lid has a profile for clamping.

Selon un mode de réalisation, le couvercle pourra comporter une interface de fixation pour un équipement.According to one embodiment, the cover may include an attachment interface for a device.

Avantageusement, la collerette et la portée annulaire comportent des dents qui sont destinées à être positionnées en regard du pare-éclats.Advantageously, the flange and the annular bearing comprise teeth which are intended to be positioned opposite the splinterguard.

L'invention a également pour objet une structure blindée comportant au moins un pare-éclats fixé à une paroi par au moins un dispositif de fixation de pare-éclats, structure caractérisée en ce que le ou les dispositifs de fixation de pare-éclats comportent :

  • une embase comportant une collerette destinée à être placée dans un lamage de la paroi, sous une première face du pare-éclats, embase comportant au moins un perçage destiné à être traversé par une vis solidaire de la paroi, embase comportant également une jupe s'étendant sensiblement perpendiculairement à la collerette au travers d'un trou du pare-éclats et abritant au moins partiellement la tête de la vis,
  • un couvercle comportant une portée annulaire prenant appui sur une seconde face du pare-éclats, couvercle comprenant des moyens assurant sa solidarisation avec la jupe et le serrage du pare-éclats.
The subject of the invention is also an armored structure comprising at least one splinter guard fixed to a wall by at least one splinterguard fixing device, structure characterized in that the one or more splinterguard fasteners comprise:
  • a base comprising a collar intended to be placed in a countersink of the wall, under a first face of the splinterguard, base comprising at least one bore to be traversed by a screw secured to the wall, base also comprising a skirt s' extending substantially perpendicular to the flange through a hole of the splinterguard and at least partially housing the head of the screw,
  • a cover having an annular bearing bearing on a second face of the splinterguard, cover comprising means ensuring its attachment to the skirt and the clamping of the splinterguard.

Avantageusement, le jeu entre la vis et l'embase est supérieur au jeu entre la collerette et le bord du lamage.Advantageously, the clearance between the screw and the base is greater than the clearance between the flange and the edge of the counterbore.

L'invention sera mieux comprise à la lecture de la description suivante, description faite en référence aux dessins annexés dans lesquels :

  • La figure 1 représente une vue en coupe d'un dispositif selon l'invention fixé sur une paroi d'une structure.
  • La figure 2 représente une vue en coupe longitudinale d'un second mode de réalisation d'un dispositif selon l'invention.
  • La figure 3 représente une vue en coupe d'un dispositif selon l'invention subissant une agression balistique.
The invention will be better understood on reading the following description, description given with reference to the accompanying drawings in which:
  • The figure 1 represents a sectional view of a device according to the invention fixed on a wall of a structure.
  • The figure 2 represents a longitudinal sectional view of a second embodiment of a device according to the invention.
  • The figure 3 represents a sectional view of a device according to the invention undergoing a ballistic aggression.

Selon la figure 1, une structure blindée (par exemple une cabine de véhicule blindé non représentée) comporte sur une face interne 6a d'une de ses parois 6 un pare-éclats 7 se présentant sous la forme d'une plaque de matériaux composites, par exemple comportant des fibres aramides de poly phénylène téréphtalamide (plus connues sous la marque déposée Kevlar).According to figure 1 , an armored structure (for example a shielded vehicle cab not shown) has on one inner face 6a of one of its walls 6 a splinterguard 7 in the form of a plate of materials composites, for example comprising aramid fibers of polyphenylene terephthalamide (better known under the trademark Kevlar).

Le pare-éclats a pour fonction d'empêcher la propagation d'éclats issus de la paroi 6 ou d'un projectile venant de l'extérieur EXT vers l'intérieur INT de la structure.The purpose of the splinterguard is to prevent the propagation of splinters coming from the wall 6 or from a projectile coming from the outside EXT towards the inside INT of the structure.

La solidarisation du pare-éclats 7 avec la paroi 6, afin de résister à l'arrachement provoqué par une agression balistique, est assurée par un dispositif de fixation 1 comportant une embase 2 et un couvercle 3. L'embase 2 comporte un perçage central 8 autour duquel s'étend une collerette 9 sensiblement plane. La collerette 9 est destinée à être placée entre la face interne 6a de la paroi 6 et une première face 7a du pare-éclats 7.The splinterguard 7 is secured with the wall 6, in order to resist tearing caused by a ballistic aggression, is ensured by a fixing device 1 comprising a base 2 and a lid 3. The base 2 comprises a central hole 8 around which extends a substantially flat flange 9. The flange 9 is intended to be placed between the inner face 6a of the wall 6 and a first face 7a of the splinterguard 7.

Pour éviter que la collerette 9 ne forme une sur-épaisseur entre la première face 7a du pare éclat 7 et la face interne 6a de la paroi 6, la collerette 9 est logée dans un lamage 6b pratiqué dans la paroi 6. La profondeur du lamage 6b est sensiblement équivalente à l'épaisseur de la collerette 9 évitant ainsi la formation d'une proéminence en surface de la face interne 6a de la paroi 6b.To prevent the flange 9 from forming an over-thickness between the first face 7a of the spark gap 7 and the inner face 6a of the wall 6, the flange 9 is housed in a counterbore 6b formed in the wall 6. The depth of the counterbore 6b is substantially equivalent to the thickness of the collar 9 thus avoiding the formation of a prominence on the surface of the inner face 6a of the wall 6b.

L'embase 2 est traversée par une vis 10 via le perçage 8. Le vissage de la vis 10 se fait dans un taraudage 6c de la paroi 6 solidarisant ainsi l'embase 2 du dispositif de fixation 1 à la paroi 6. La pression de serrage de la tête de vis 10 est répartie sur l'embase 2 grâce à une rondelle 11.The base 2 is traversed by a screw 10 via the bore 8. The screwing screw 10 is in a tapping 6c of the wall 6 thus securing the base 2 of the fastening device 1 to the wall 6. The pressure of tightening of the screw head 10 is distributed on the base 2 by means of a washer 11.

L'embase comporte une jupe 12 sensiblement concentrique au perçage 8 et qui comporte un filetage 12a. La jupe 12 s'élève sensiblement perpendiculairement à la collerette 4 et elle traverse un trou 7c du pare-éclats 7. Le filetage 12a correspond avec un taraudage 13a qui est porté par un prolongement cylindrique 13 d'un couvercle 3. Le prolongement cylindrique 13 s'étend sensiblement perpendiculairement au plan d'une portée annulaire 5 du couvercle 3 et constitue un moyen de solidarisation du couvercle 3 avec la jupe 12. L'inclusion de la collerette 9 dans le lamage 6b offre un appui latéral au dispositif de fixation lors des phases où le pare éclat 7 se translate le long de la paroi 6. La vis 10 n'est alors pas sollicitée en cisaillement, les efforts transmis par le pare éclats 7 étant repris au niveau de la jupe 12. On notera que le jeu J1 entre collerette 9 et bord de lamage 6b est inférieur au jeu J2 entre vis 10 et embase 2 afin que la tête de vis ne soit pas sollicitée en cisaillement.The base comprises a skirt 12 substantially concentric with the bore 8 and which has a thread 12a. The skirt 12 rises substantially perpendicularly to the flange 4 and passes through a hole 7c of the splinterguard 7. The threading 12a corresponds to a tapping 13a which is carried by a cylindrical extension 13 of a lid 3. The cylindrical extension 13 extends substantially perpendicular to the plane of an annular bearing surface 5 of the cover 3 and constitutes a means for securing the lid 3 with the skirt 12. The inclusion of the flange 9 in the counterbore 6b provides lateral support for the fastening device during the phases in which the fl ap 7 is translated along the wall 6. The screw 10 is then not biased in shear, the forces transmitted by the splinter 7 being taken up at the level of the skirt 12. It will be noted that the clearance J1 between the flange 9 and the countersink edge 6b is smaller than the clearance J2 between the screw 10 and the base 2 so that the screw head is not stressed in shear.

Le prolongement cylindrique 13 recouvre la tête de la vis 10. En cas de rupture de la vis 10 la tête est donc confinée dans un logement 21 formé par l'intérieur de la jupe 12 et du prolongement cylindrique 13 vissés l'un sur l'autre.The cylindrical extension 13 covers the head of the screw 10. In the event of rupture of the screw 10, the head is thus confined in a housing 21 formed by the inside of the skirt 12 and the cylindrical extension 13 screwed one onto the other.

L'extérieur du prolongement cylindrique 13 est sensiblement circulaire et correspond avec le trou 7c pratiqué dans le pare-éclats 7.The outside of the cylindrical extension 13 is substantially circular and corresponds with the hole 7c formed in the splinterguard 7.

La portée annulaire 5, s'étendant autour du prolongement cylindrique 13, est plaquée contre la seconde face 7b du pare-éclats 7 par l'action de vissage du couvercle 3 sur l'embase 2.The annular span 5, extending around the cylindrical extension 13, is pressed against the second face 7b of the splinterguard 7 by the screwing action of the cover 3 on the base 2.

Le pare-éclats 7 est ainsi pincé entre la collerette 4 de l'embase 2 et la portée annulaire 5 du couvercle 3. Le pare-éclats 7 est ainsi solidaire de la paroi 6.The splinter guard 7 is thus clamped between the flange 4 of the base 2 and the annular surface 5 of the cover 3. The splinterguard 7 is thus integral with the wall 6.

Ainsi, selon la figure 3, en cas d'agression balistique venant à provoquer la rupture de la vis 10 et le décollement du pare-éclats 7 de la paroi 6, le dispositif de fixation 1 n'est pas librement projeté dans le véhicule mais reste accroché au pare-éclats 7 qui limite alors la course du dispositif de fixation 1. Par ailleurs le dispositif de fixation 1 retient la tête de vis 10 dans le logement 21, évitant ainsi de blesser les occupants du véhicule.So, according to the figure 3 , in case of ballistic aggression provoking the breaking of the screw 10 and the detachment of the splinterguard 7 from the wall 6, the fixing device 1 is not freely projected into the vehicle but remains attached to the splinterguard 7 which then limits the travel of the fastening device 1. Moreover, the fastening device 1 retains the screw head 10 in the housing 21, thus avoiding injuring the occupants of the vehicle.

Le serrage du couvercle 3 sur l'embase 2 pourra être effectué par exemple grâce à un profil ou une forme saillante hexagonale 22 apte à correspondre avec une clé de serrage (clé non représentée) et située sur la face du couvercle 3 dirigée vers l'intérieur INT de la structure.The tightening of the cover 3 on the base 2 may be carried out for example by means of a profile or a protruding shape hexagonal 22 adapted to correspond with a tightening key (key not shown) and located on the face of the lid 3 directed inward INT of the structure.

Selon la figure 2, le couvercle comporte une interface 15 de fixation d'un équipement de bord 16. En l'espèce, à la figure 2, une seconde vis cylindrique 15 à tête hexagonale creuse fixe un support d'arme individuelle 16 grâce à un taraudage 17 pratiqué dans le couvercle 3.According to figure 2 , the cover has an interface 15 for attaching an on-board equipment 16. In this case, at the figure 2 a second hollow hexagonal screw 15 secures an individual weapon support 16 by means of a thread 17 made in the cover 3.

On notera que dans ce mode de réalisation le prolongement cylindrique 13 du couvercle 3 porte un filetage qui s'engage dans un taraudage de la jupe 12 de l'embase.Note that in this embodiment the cylindrical extension 13 of the lid 3 carries a thread which engages in a tapping of the skirt 12 of the base.

La jupe 12 de l'embase 2 comporte par ailleurs une portée cylindrique 23 permettant ainsi au pare-éclats 7 d'être centré sur cette portée 23 lors du montage.The skirt 12 of the base 2 also has a cylindrical surface 23 thus allowing the splinterguard 7 to be centered on this surface 23 during assembly.

Dans le mode de réalisation de la figure 2, la collerette 4 et la portée annulaire 5 comportent des dents 20 (sous forme de picots ou de dentures circulaires). Ces dents 20 sont aptes à favoriser la liaison entre le pare-éclats 7 et le dispositif 1 pour éviter le glissement du pare-éclats entre la collerette 4 et la portée annulaire 5 durant un décollement du pare-éclats 7.In the embodiment of the figure 2 the collar 4 and the annular bearing surface 5 comprise teeth 20 (in the form of pins or circular teeth). These teeth 20 are able to promote the connection between the splinterguard 7 and the device 1 to prevent the sliding of the splinterguard between the flange 4 and the annular bearing surface 5 during a detachment of the splinterguard 7.
