Description

La présente invention se rapporte d'une manière générale à un fil électrique.The present invention relates generally to an electric wire.

Elle vise plus particulièrement un filet de protection réalisé à partir d'un tel fil et permettant la surveillance de zones sensibles.It relates more particularly to a protective net produced from such a wire and allowing the surveillance of sensitive areas.

On a déjà proposé diverses structures de câble pour la fabrication de clôtures empêchant les personnes de les franchir et permettant, en cas d'effraction, de réaliser une détection électrique instantanée du passage de ces personnes.Various cable structures have already been proposed for the manufacture of fences preventing people from crossing them and making it possible, in the event of a break-in, to carry out instant electrical detection of the passage of these people.

De tels câbles pouvaient par exemple être rapportés sur un grillage constituant la clôture.Such cables could for example be attached to a fence constituting the fence.

Toutefois, un tel système de protection demeurait relativement coûteux à réaliser et on obtenait une clôture non unitaire, présentant une structure quelque peu complexe et nécessitant un entretien périodique.However, such a protection system remained relatively expensive to produce and a non-unitary fence was obtained, having a somewhat complex structure and requiring periodic maintenance.

La présente invention a pour but de remédier à ces inconvénients en proposant un système de protection particulièrement simple, peu coûteux, unitaire, souple et se prêtant à une mise en place facile sur un site quelconque.The object of the present invention is to remedy these drawbacks by proposing a particularly simple, inexpensive, unitary, flexible protection system suitable for easy installation on any site.

A cet effet, l'invention a pour objet un fil électriquement conducteur comprenant une âme électriquement conductrice entourée d'un revêtement en fibres synthétiques constituant de préférence une tresse, caractérisé en ce qu'il constitue un filet à mailles nouées et électriquement raccordable à un moyen de signalisation quelconque d'une coupure ou analogue dans ledit filet.To this end, the subject of the invention is an electrically conductive wire comprising an electrically conductive core surrounded by a covering of synthetic fibers preferably constituting a braid, characterized in that it constitutes a knitted mesh net and electrically connectable to a means for any signaling of a cut or the like in said net.

L'âme conductrice peut être constituée de deux fils torsadés sous gaine en matière isolante.The conductive core may consist of two wires twisted in a sheath of insulating material.

Selon une autre caractéristique de l'invention, le revêtement extérieur formant tresse peut être imprégné d'une couche de matériau imperméable ce qui permet notamment son utilisation sous l'eau.According to another characteristic of the invention, the outer covering forming a braid can be impregnated with a layer of impermeable material, which in particular allows it to be used underwater.

Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :

  • La figure 1 est une vue en perspective d'une portion de filet réalisé conformément aux principes de l'inven­tion ; et
  • Les figures 2 et 3 sont des vues en élévation de ce filet utilisé respectivement pour obturer un passage sous l'eau par exemple ou pour recouvrir un objet à protéger.
However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which:
  • Figure 1 is a perspective view of a portion of net produced in accordance with the principles of the invention; and
  • Figures 2 and 3 are elevational views of this net used respectively to close a passage under water for example or to cover an object to be protected.

En se reportant à la figure 1, on voit qu'un fil électriquement conducteur, selon cette invention est noué pour constituer un filet 1 comportant des mailles 3 de dimensions quelconques et reliées par des noeuds 2.Referring to FIG. 1, it can be seen that an electrically conductive wire, according to this invention is knotted to form a net 1 comprising meshes 3 of any size and connected by nodes 2.

Ce filet 1 est réalisé à partir d'un fil électriquement conducteur comprenant une âme électriquement conductrice entourée d'un revêtement en fibres synthétiques constituant une tresse 4.This net 1 is produced from an electrically conductive wire comprising an electrically conductive core surrounded by a covering of synthetic fibers constituting a braid 4.

Cette tresse est de préférence imprégné d'une couche de matériau étanche aux intempéries et à l'eau.This braid is preferably impregnated with a layer of weatherproof and waterproof material.

L'âme électriquement conductrice, suivant l'exemple de réalisation représenté, est constituée de deux fils torsadés 5, chaque fil étant constitué d'un fil métallique électriquement conducteur sous gaine en matière isolante.The electrically conductive core, according to the embodiment shown, consists of two wires twisted 5, each wire consisting of an electrically conductive metal wire in an insulating sheath.

On pourrait parfaitement, sans sortir du cadre de l'invention, utiliser un seul fil tel que 5, ou même plus de deux fils, étant entendu que ce ou ces fils présenteront la souplesse requise pour pouvoir, avec la tresse 4, réaliser les noeuds 2 entre mailles 3 sans risque de détérioration ou de coupure au niveau de ces noeuds.We could perfectly, without departing from the scope of the invention, use a single thread such as 5, or even more than two threads, it being understood that this or these threads will have the flexibility required to be able, with the braid 4, to make the knots 2 between meshes 3 without risk of deterioration or cutting at these nodes.

On comprend donc que le filet 1 réalisé selon les principes de cette invention, constitue un ensemble unitaire, souple, relativement léger et pouvant être utilisé sur un site sensible quelconque à protéger.It is therefore understood that the net 1 produced according to the principles of this invention constitutes a unitary, flexible, relatively light assembly which can be used on any sensitive site to be protected.

C'est ainsi que, sur la figure 2, on a montré le filet 1 bouchant une passe 6, sous l'eau par exemple. Le filet 1 peut être maintenu en partie haute par des flotteurs 7, et en partie basse par tout système approprié, tel qu'une chaîne montrée schématiquement en 8.Thus, in Figure 2, we showed the net 1 blocking a pass 6, underwater for example. The net 1 can be held in the upper part by floats 7, and in the lower part by any suitable system, such as a chain shown diagrammatically at 8.

Sur la figure 3, on a montré le filet 1, selon cette invention, recouvrant une charge quelconque 9 à protéger, ledit filet étant bien entendu ancré au sol par tout moyen approprié.In FIG. 3, the net 1 has been shown, according to this invention, covering any load 9 to be protected, said net being of course anchored to the ground by any suitable means.

Bien entendu, le filet 1 sera raccordé à un moyen quelconque de signalisation visuelle et/ou auditive (non représenté) qui sera actionné lors d'une coupure ou analogue dans le filet.Of course, the net 1 will be connected to any means of visual and / or auditory signaling (not shown) which will be actuated during a cut or the like in the net.

On a donc réalisé suivant l'invention un filet de protection qui peut être installé très facilement et très rapidement dans une zone sensible quelconque ou sur un objet quelconque et dans un milieu ambiant quelconque pour protéger efficacement cette zone ou cet objet.A protective net has therefore been produced according to the invention which can be installed very easily and very quickly in any sensitive area or on any object and in any ambient environment to effectively protect this area or object.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

C'est ainsi que l'âme conductrice du fil électrique constituant le filet pourrait être fabriquée d'une manière quelconque, sans sortir du cadre de l'invention, à la condition que cette âme puisse bien sûr permettre la fabrication d'un filet à mailles nouées conforme à cette invention.Thus the conductive core of the electric wire constituting the net could be manufactured in any way, without departing from the scope of the invention, provided that this core can of course allow the manufacture of a net to knitted stitches according to this invention.

L'invention comprend donc tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.The invention therefore includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
