Abstract

This modular screen is characterised in that it comprises a support structure 1 which can be deformed and is resistant to traction, under which is fixed a layer 2 of material which is impermeable to the toxic falling matter (fallout). Advantageously, the support structure 1 comprises a camouflage net, comprising a rope net and the edges of this support structure and of this layer of material impermeable to the toxic falling matter (fallout) comprise means 3, 4, 5 for fixing this screen to an adjacent element. This modular screen may be used in an enclosure of protection against toxic agents in liquid, solid or gaseous form, in which the edges of the screen are fixed on any support, and its inside is connected to a unit for blowing and filtering air, in order to create an above-atmospheric pressure of uncontaminated air inside the enclosure.

Description

La' présente invention concerne un écran modulaire de protection contre des retombées toxiques et une application de cet écran modulaire dans une enceinte de protection contre des agents toxiques sous forme liquide, solide ou gazeuse. The present invention relates to a modular screen for protection against toxic fallout and an application of this modular screen in a protective enclosure against toxic agents in liquid, solid or gaseous form.

On connait déjà dans ltétat de la technique, des combinaisons permettant de protéger le personnel, par exemple militaire, contre des retombées toxiques. In the state of the art, combinations are already known which make it possible to protect personnel, for example military personnel, against toxic fallout.

Cependant, ces moyens de protection sont individuels et ne permettent pas de protéger simultanément plusieurs personnes ou un matériel quelconque. However, these means of protection are individual and do not allow several people or any equipment to be protected simultaneously.

Par ailleurs, il n'existe pas non plus d'enceintes de protection contre des agents toxiques sous forme liquide, solide ou gazeuse, qui soient facilement démontables et transportables et qui puissent etre mises en oeuvre trés rapidement dans des condi- tions difficiles. Furthermore, there are also no protective enclosures against toxic agents in liquid, solid or gaseous form, which are easily removable and transportable and which can be implemented very quickly under difficult conditions.

Le but de l'invention est donc de résoudre ces problèmes en proposant un écran modulaire de protection contre des retombées toxiques qui soit simple, fiable d'un prix de revient peu élevé, qui puisse etre stocké et transporté rapidement et qui soit facilement adaptable en fonction de la protection souhaitée. The object of the invention is therefore to solve these problems by proposing a modular screen for protection against toxic fallout which is simple, reliable at a low cost price, which can be stored and transported quickly and which is easily adaptable to depending on the desired protection.

A cet effetil invention a pour objet un écran modulaire de protection contre des retombées toxiques caractérisé en ce qu'il comporte une structure de support déformable et résistante à la traction sous laquelle est fixée une couche de matériau imperméable aux retombées toxiques. To this end, the invention relates to a modular screen for protection against toxic fallout, characterized in that it comprises a deformable and tensile-resistant support structure under which is fixed a layer of material impermeable to toxic fallout.

Avantageusement. la structure de support comprend un filet de camouflage comportant un filet en cordage. Advantageously. the support structure includes a camouflage net having a rope net.

Selon un autre aspect, l'invention a égale ment pour objet une enceinte de protection contre des agents toxiques sous forme liquidelsolide ou gazeuse, caractérisée en ce qu'elle comporte au moins un écran selon 1 une quelconque des revendications précédentes dont les bords sont fixés sur un support quelconque, et dont l'intérieur est relié à un groupe de soufflage et de filtration d'air disposé à l'extérieur de l'enceinte, pour mettre l'intérieur de celle-ci en surpression avec de l'air non contaminé. According to another aspect, the invention also relates to a protective enclosure against toxic agents in liquid or solid or gaseous form, characterized in that it comprises at least one screen according to any one of the preceding claims, the edges of which are fixed. on any support, and the interior of which is connected to a blowing and air filtration unit arranged outside the enclosure, to put the interior thereof under overpressure with non-air contaminated.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels
- la Fig.l représente une vue schématique en perspective d'un écran modulaire selon l'invention; et
- la Fig.2 représente une enceinte dé protection comportant un tel écran.The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which
- Fig.l shows a schematic perspective view of a modular screen according to the invention; and
- Fig.2 shows a protective enclosure comprising such a screen.

Comme on peut le voir sur la Fiv. 1, un écran modulaire de protection contre des retombées toxiques, selon l'invention, comporte une structure de support l déformable et résistante à la traction sous laquelle est fixée une couche 2 de matériau imperméable aux retombées toxiques. La structure de support 1 est avantageusement constituée par un filet de camouflage par exemple contre une détection visuelle en étant peinte en différentes couleurs, ou encore contre des détections par radars ou thermiques comme cela est connu. As can be seen on Fiv. 1, a modular screen for protection against toxic fallout, according to the invention, comprises a support structure l deformable and resistant to traction under which is fixed a layer 2 of material impermeable to toxic fallout. The support structure 1 is advantageously constituted by a camouflage net for example against visual detection by being painted in different colors, or even against detections by radars or thermals as is known.

La structure de support et la couche de matériau imperméable aux retombées toxiques, comprennent au moins sur un coté des moyens 3 d'accrochage à un élément adjacent. The support structure and the layer of material impermeable to toxic fallout, comprise at least on one side means 3 for hooking to an adjacent element.

Ces moyens d accrochage sont constitués, pour la structure de support 1, par des boucles de cordage 4 permettant de fixer la structure de support à la structure de support d'un élément adjacent ou sur un support quelconque comme par exemple le so-l comme cela sera décrit plus en détail par la suite. These attachment means are constituted, for the support structure 1, by rope loops 4 making it possible to fix the support structure to the support structure of an adjacent element or on any support such as for example the so-l as this will be described in more detail later.

Les moyens d'accrochage prévus sur la couche 2 de matériau imperméable aux retombées toxiques, peuvent etre, quant à eux, constitués par des fermetures à glissières étanches prévues sur au moins un coté de la couche de matériau imperméable aux retombées toxiques, cette couche étant légèrement plus grande que le filet de camouflage pour permettre une fixation plus facile des éléments les uns sur les autres. Ces fermetures à glissières étanches permettent d obtenir une continuité de protection quel que soit le nombre d'écrans fixés les uns sur les autres. The attachment means provided on the layer 2 of material impermeable to toxic fallout, may be, in turn, constituted by tight zippers provided on at least one side of the layer of material impermeable to toxic fallout, this layer being slightly larger than the camouflage net to allow easier attachment of the elements on top of each other. These waterproof slide fasteners provide continuity of protection regardless of the number of screens attached to each other.

Cette couche de matériau de protection peut entre de type connu en soi et peut entre constituée par exemple par un complexe de film PVC-film polyester. This layer of protective material can be of a type known per se and can for example consist of a complex of PVC film-polyester film.

Avantageusement, cette couche de matériau de protection est collée sur la structure de support. Advantageously, this layer of protective material is bonded to the support structure.

Comme on peut le voir sur la Fig.2, un écran modulaire de protection selon l'invention peut trouver des applications dans une enceinte 6 de p-rotection contre des agents toxiques sous forme liquide, solide ou gazeuse. As can be seen in FIG. 2, a modular protection screen according to the invention can find applications in an enclosure 6 for p-rotection against toxic agents in liquid, solid or gaseous form.

Dans ce cas. cette enceinte comporte au moins un écran tel que défini précédemment, dont les bords sont fixés sur un support quelconque, tel que par exemple le sol, et cette enceinte 6 est reliée par exemple par l intermédiaire d'un conduit 7 à un groupe 8 de soufflage et de ventilation d'air disposé à l'ex- térieur de l'enceinte 6, pour mettre l'intérieur de celle cri en surpression avec de l'air non contaminé et donc protéger l'intérieur de cette enceinte contre toutes retombées toxiques, sous forme liquide ou soli de et toutes pénétrations de gaz à l'intérieur de l'enceinte, en créant une circulation d'air vers l'extérieur entre les bords de l'enceinte et le sol.  In that case. this enclosure comprises at least one screen as defined above, the edges of which are fixed on any support, such as for example the ground, and this enclosure 6 is connected for example by the intermediary of a conduit 7 to a group 8 of blowing and ventilation of air placed outside the enclosure 6, to put the interior of the cry overpressure with uncontaminated air and therefore protect the interior of this enclosure against any toxic fallout , in liquid or soli form and all gas penetrations inside the enclosure, creating an air circulation towards the outside between the edges of the enclosure and the ground.
