Abstract
Description
La présente invention a pour objet un perfectionnement apporté aux clôtures de sécurité revendiquées à la revendication I de la demande principale NO 81-15074. The present invention relates to an improvement made to the security fences claimed in claim I of the main application NO 81-15074.
On a décrit et revendiqué dans cette demande une clôture de sécurité comportant essentiellement en combinaison une âme métallique centrale et un brin conducteur noyé dans l'enroba- ge plastique de ladite âme métallique. A security fence has been described and claimed in this application essentially comprising in combination a central metallic core and a conductive strand embedded in the plastic coating of said metallic core.
Bien que cette réalisation donne entière satisfaction, il est appary cependant qu'il était encore possible d'améliorer le dispositif- tant au niveau de sa fabrication qu'au niveau de son utilisation, si l'on prévoyait une clôture de sécurité selon la revendication I du brevet principal, caractérisée en ce que l'élément conducteur est appliqué par un traitement de surface directement sur la gaine plastique enrobant l'amie centrale, l'ensemble étant ultérieurement soumis à une nouvelle plastification ou enduction par tout isolant approprié. Although this achievement is entirely satisfactory, it is however apparent that it was still possible to improve the device, both in terms of its manufacture and in terms of its use, if a safety fence according to the claim was provided. I of the main patent, characterized in that the conductive element is applied by a surface treatment directly on the plastic sheath coating the central friend, the assembly being subsequently subjected to a new plasticization or coating with any suitable insulator.
On peut ainsi réaliser sur un treillis métallique plastifié un véritable circuit imprimé, l'application du traitement de surface pouvant être sélective et déterminant des circuits conducteurs qui sont ensuite alimentés et surveillés de la même manière que dans le brevet principal. A real printed circuit can thus be produced on a plastic wire mesh, the application of the surface treatment being able to be selective and determining the conductive circuits which are then supplied and monitored in the same way as in the main patent.
Le traitement de surface pourra être, non limitativement, une métallisation, selon des techniques en elles-mêmes connues qui ne seront pas décrites plus en détails. The surface treatment may be, without limitation, metallization, according to techniques in themselves known which will not be described in more detail.
On comprendra mieux l'invention à l'aide de la description ci-après d'un mode préféré de mise en oeuvre en référence aux dessins annexés dans lesquels
- la figure I est une vue schématique en coupe longitudinale d'un élément conducteur utilisé pour la clôture conforme à l'invention,
- la figure 2 illustre la réalisation d'un circuit conducteur sur treillis plastifié, par un traitement de surface,
- la figure 3 illustre un mode de mise en oeuvre particulièrement avantageux de la clôture selon la figure 2.The invention will be better understood using the description below of a preferred embodiment with reference to the accompanying drawings in which
FIG. I is a schematic view in longitudinal section of a conductive element used for the fence according to the invention,
FIG. 2 illustrates the production of a conductive circuit on a plastic mesh, by a surface treatment,
FIG. 3 illustrates a particularly advantageous embodiment of the fence according to FIG. 2.
Un fil traité conformément à l'invention comporte
- une âme métallique centrale (1),
- une couche isolante (2), par exemple une couche plastique,
- une couche conductrice (3) appliqué par traitement de surface, par exemple par métallisation,
- une couche extérieure isolante (4).A wire treated in accordance with the invention comprises
- a central metallic core (1),
- an insulating layer (2), for example a plastic layer,
- a conductive layer (3) applied by surface treatment, for example by metallization,
- an insulating outer layer (4).
On a représenté à la figure 2 un exemple de réalisation de circuits imprimés sur un treillis métallique plastifié (5). There is shown in Figure 2 an embodiment of printed circuits on a plasticized wire mesh (5).
Le traitement de surface est appliqué de manière selective de manière à déterminer des circuits tels que (6,7,8). The surface treatment is applied selectively so as to determine circuits such as (6,7,8).
Puis on réalise une isolation soit par plastification, soit par projection de tout élément isolant adéquat.Then an insulation is carried out either by plasticization, or by projection of any suitable insulating element.
Enfin on a représenté à la figure 3 un dispositif de sécurité supplémentaire détectant toute effraction tendant à faire basculer la partie supérieure du grillage. Finally, FIG. 3 shows an additional security device detecting any break-in tending to cause the upper part of the screen to tip over.
Sur les poteaux de liaison (9,10) on dispose les éléments de détection dynamométrique consistant essentiellement en deux barres (I 1,12) symétriques montées à rotation autour d'un point des poteaux et commandant à l'intérieur de chaque poteau un moyen de pincement des fils de clôture, déclenchant ainsi l'alarme, les moyens de pincement sont munis d'un ressort de rappel les ramenant en position lorsque la sollicitation cesse. On the connecting posts (9,10) there are the dynamometric detection elements consisting essentially of two symmetrical bars (I 1,12) mounted in rotation around a point of the posts and controlling inside each post a means pinching the fence wires, thus triggering the alarm, the pinching means are provided with a return spring bringing them back into position when the stress ceases.
Enfin sur les barres (11,12) on tend des fils barbelés en saillie latérale par rapport au plan du grillage et comportant un brin conducteur réalisé également par métallisation. Finally on the bars (11,12) are stretched barbed wires projecting laterally from the plane of the mesh and comprising a conductive strand also produced by metallization.
On obtient ainsi une protection complète :
- détection sur le grillage pour la rupture et toute détérioration,
- détection dynamométrique sur les barres des poteaux de liaison,
- détection pour la rupture et la détérioration des fils barbelés This provides complete protection:
- detection on the mesh for rupture and any deterioration,
- dynamometric detection on the bars of the connecting posts,
- detection for breakage and deterioration of barbed wire
