Description

Domaine technique de l'inventionTechnical field of the invention

L'invention se rapporte au domaine technique des clôtures de protection permettant de détecter une tentative d'intrusion à l'intérieur d'un périmètre délimité par la clôture. Plus particulièrement elle se rapport au domaine des clôtures de protection comportant des panneaux montés sur une ossature comportant des poteaux de fixation.The invention relates to the technical field of protection fences for detecting an intrusion attempt inside a perimeter delimited by the fence. More particularly, it relates to the field of protective fences comprising panels mounted on a frame comprising fixing posts.

Etat de la techniqueState of the art

Une clôture de protection comprend tout d'abord une ossature qui se compose d'éléments de structure. Ces éléments de structure comportent des poteaux de fixation, généralement verticaux et, le cas échéant, des traverses généralement horizontales qui relient deux poteaux voisins. Cette clôture comprend en outre différents panneaux de clôture montés sur cette ossature, par l'intermédiaire de moyens de fixation, typiquement par vissage. Les panneaux de clôture délimitent au moins en partie un enclos, de manière à former une barrière physique destinée à empêcher une personne de pénétrer dans le périmètre de cet enclos.A protection fence firstly comprises a frame which consists of structural elements. These structural elements comprise fixing posts, generally vertical and, where appropriate, generally horizontal crosspieces which connect two adjacent posts. This fence further comprises various fence panels mounted on this frame, by means of fixing means, typically by screwing. The fence panels at least partially delineate an enclosure so as to form a physical barrier to prevent a person from entering the perimeter of the enclosure.

L'invention vise plus particulièrement une telle clôture de protection, dans laquelle chaque panneau comprend deux plaques parallèles, qui sont séparées par des moyens d'isolation électrique. Ces plaques peuvent être rigides, semi-rigides ou flexibles. Elles peuvent être pleines ou au moins partiellement ajourées. Au sens de l'invention, elles peuvent être formées par un treillis, notamment un treillis métallique.The invention relates more particularly to such a protective fence, wherein each panel comprises two parallel plates, which are separated by electrical insulation means. These plates can be rigid, semi-rigid or flexible. They can be full or at least partially openwork. Within the meaning of the invention, they may be formed by a lattice, in particular a wire mesh.

Les moyens d'isolation précités, qui sont typiquement formés par une couche de colle, permettent aux deux plaques de ne pas être en contact électrique mutuel. Les deux plaques constitutives d'un panneau donné sont raccordées respectivement, l'une à la masse et l'autre à la phase. Par conséquent, si l'une des plaques est percée ou sciée, lors d'une tentative d'intrusion, il se forme au moins temporairement un court-circuit avec l'outil ou avec des copeaux métalliques, lequel sera détecté.The aforementioned insulation means, which are typically formed by a layer of glue, allow the two plates not to be in mutual electrical contact. The two constituent plates of a given panel are connected respectively, one to the ground and the other to the phase. Therefore, if one of the plates is pierced or sawed, during an intrusion attempt, at least a temporary short circuit is formed with the tool or with metal chips, which will be detected.

Lorsque la clôture est formée de plusieurs panneaux, toutes les plaques de masse sont reliées électriquement entre elles, alors que toutes les plaques de phase sont reliées électriquement entre elles. Ces deux ensembles de plaques forment donc deux circuits dits respectivement « de masse » et « de phase », reliés aux pôles d'un système d'alarme qui détecte le court-circuit entre ces deux circuits.When the fence is formed of several panels, all the ground plates are electrically connected to each other, while all the phase plates are electrically connected to each other. These two sets of plates thus form two so-called "ground" and "phase" circuits, connected to the poles of an alarm system which detects the short circuit between these two circuits.

On conçoit que, afin d'assurer un fonctionnement optimal de la clôture de sécurité, les circuits respectifs de masse et de phase doivent être isolés mutuellement. Il convient en particulier de prendre des dispositions constructives, afin que les moyens de fixation des panneaux sur le bâti ne soient pas la cause d'un court-circuit.It is conceivable that, in order to ensure optimum operation of the safety fence, the respective circuits of mass and phase must be mutually isolated. In particular, it is necessary to make constructive arrangements, so that the means of fixing the panels on the frame are not the cause of a short circuit.

On connaît de FR 2 937 360 A1 et EP 2 178 055 A1 (Euroclôture) une clôture de sécurité telle que décrite ci-dessus, dans laquelle deux panneaux adjacents sont fixés mutuellement par un goujon s'étendant à travers une zone de recouvrement, dans laquelle ces deux panneaux sont mutuellement superposés. Ce goujon coopère en outre avec un poteau du bâti, ce qui assure la solidarisation de ces plaques sur ce poteau. Afin d'assurer la continuité électrique, les plaques en regard de ces panneaux sont dénudées au niveau de cette zone de recouvrement.We know FR 2 937 360 A1 and EP 2 178 055 A1 (Euroclôture) a security fence as described above, wherein two adjacent panels are mutually secured by a stud extending through an overlap area, wherein these two panels are mutually superimposed. This stud cooperates further with a pole of the frame, which ensures the joining of these plates on this pole. In order to ensure electrical continuity, the plates facing these panels are stripped at this overlap area.

Cette solution connue présente cependant certains inconvénients. En effet, la clôture de sécurité décrite dans ce document possède une épaisseur relativement importante. De plus, cette clôture présente une structure mécanique complexe, en particulier dans la zone de fixation des panneaux sur le poteau. Puis, le besoin d'avoir des zones dénudées au niveau de la zone de recouvrement des panneaux complique la protection contre la corrosion et l'assemblage de la clôture. Enfin, la maintenance de cette clôture peut se révéler peu commode, en particulier lors d'une rupture mécanique des moyens de fixation et / ou d'un disfonctionnement dans la continuité électrique.This known solution, however, has certain disadvantages. Indeed, the security fence described in this document has a relatively large thickness. In addition, this fence has a complex mechanical structure, particularly in the area of attachment of the panels on the pole. Then, the need for bare areas at the panel overlap area complicates corrosion protection and fence assembly. Finally, the maintenance of this fence can be inconvenient, especially during a mechanical breakage of the fastening means and / or a malfunction in the electrical continuity.

Il existe par conséquent un besoin manifeste de clôtures, permettant de remédier aux inconvénients de l'art antérieur évoqués ci-dessus.There is therefore a clear need for fencing, to overcome the disadvantages of the prior art mentioned above.

Objets de l'inventionObjects of the invention

Un premier objet de l'invention est une clôture de sécurité comprenant

  • une ossature comportant des éléments de structure,
  • au moins deux panneaux, chaque panneau comportant au moins une première et une seconde plaques assemblées l'une au voisinage de l'autre, ainsi que des moyens d'isolation électrique entre les deux plaques,
  • des moyens de fixation de chaque panneau sur au moins un élément de structure,
  • des premiers moyens de liaison électrique entre les premières plaques d'au moins deux panneaux adjacents, ces panneaux adjacents s'étendant selon deux plans principaux, ainsi que des seconds moyens de liaison électrique entre les secondes plaques desdits au moins deux panneaux adjacents,
  • des moyens de raccordement à une masse des premières plaques, dites plaques de masse, ainsi que des moyens de raccordement à une phase des secondes plaques, dites plaques de phase,
ladite clôture étant caractérisée en ce que lesdits panneaux adjacents ne se recouvrent pas, lorsqu'ils sont vus selon une direction perpendiculaire à l'un ou l'autre de leurs plans principaux.A first object of the invention is a security fence comprising
  • a framework comprising structural elements,
  • at least two panels, each panel comprising at least a first and a second assembled plate one in the vicinity of the other, as well as electrical insulation means between the two plates,
  • means for fixing each panel on at least one structural element,
  • first electrical connection means between the first plates of at least two adjacent panels, these adjacent panels extending in two main planes, as well as second electrical connection means between the second plates of said at least two adjacent panels,
  • means for connection to a mass of the first plates, called ground plates, as well as connection means to a phase of the second plates, called phase plates,
said fence being characterized in that said adjacent panels do not overlap, when viewed in a direction perpendicular to one or other of their main planes.

La clôture de sécurité conforme à l'invention est avantageuse, par rapport à l'enseignement de FR 2 937 360 . En effet, étant donné que les panneaux adjacents ne se recouvrent pas, l'épaisseur globale de la clôture peut être réduite par rapport à l'art antérieur. A cet égard, on notera que dans FR 2 937 360 , cette épaisseur globale est nécessairement augmentée de la somme des deux épaisseurs des panneaux.The security fence according to the invention is advantageous, compared to the teaching of FR 2,937,360 . Indeed, since the adjacent panels do not overlap, the overall thickness of the fence can be reduced compared to the prior art. In this respect, it should be noted that FR 2,937,360 this overall thickness is necessarily increased by the sum of the two thicknesses of the panels.

De plus la structure des moyens de fixation, utilisés dans la clôture de l'invention, peut être simplifiée. En particulier, il n'est pas nécessaire de prévoir des moyens uniques, assurant la fixation simultanée des deux plaques sur l'élément de structure. De ce fait, il est possible de démonter un panneau par rapport à l'élément de structure, sans interférer sur la fixation de l'autre de ces panneaux.In addition, the structure of the fixing means used in the enclosure of the invention can be simplified. In particular, it is not necessary to provide unique means, ensuring the simultaneous fixing of the two plates on the structural element. Therefore, it is possible to disassemble a panel relative to the structural element, without interfering on the attachment of the other of these panels.

Selon un mode de réalisation de l'invention, les panneaux adjacents s'étendent selon deux plans principaux parallèles, et en particulier les deux panneaux adjacents s'étendent dans le même plan. Ceci est avantageux en ce qui concerne la compacité globale de la clôture, notamment son épaisseur.According to one embodiment of the invention, the adjacent panels extend in two parallel main planes, and in particular the two adjacent panels extend in the same plane. This is advantageous as regards the overall compactness of the fence, especially its thickness.

De façon avantageuse, les chants des deux panneaux adjacents s'étendent de part et d'autre de l'élément de structure. Ceci permet de réduire l'interaction mécanique entre les deux panneaux, ce qui permet par exemple une intervention sur l'un de ces panneaux, sans avoir à interférer sur la fixation de l'autre de ces panneaux sur le bâti.Advantageously, the edges of the two adjacent panels extend on either side of the structural element. This reduces the mechanical interaction between the two panels, which allows for example an intervention on one of these panels, without having to interfere with the attachment of the other of these panels on the frame.

De façon avantageuse, les plans principaux des deux panneaux adjacents traversent l'élément de structure. La surépaisseur due à la présence des panneaux est donc limitée, voire inexistante.Advantageously, the main planes of the two adjacent panels pass through the structural element. The extra thickness due to the presence of the panels is therefore limited or non-existent.

De façon avantageuse, toutes les plaques de masse sont disposées d'un premier côté de la clôture, alors que toutes les plaques de phase sont disposées du côté opposé de la clôture. Ceci permet de limiter les risques de disfonctionnement électrique.Advantageously, all the ground plates are arranged on a first side of the fence, while all the phase plates are arranged on the opposite side of the fence. This makes it possible to limit the risks of electrical malfunction.

Selon un mode de réalisation avantageux de l'invention, les moyens de liaison comprennent un organe de liaison comportant une première zone de montage, en particulier de montage amovible, sur une plaque de masse ou de phase appartenant à un premier panneau, ainsi qu'une seconde zone de montage, en particulier de montage amovible, sur une plaque de masse ou de phase appartenant à un second panneau. Selon un mode de réalisation de l'invention, l'organe de liaison comporte en outre une zone de transition entre lesdites zones de montage, cette zone de transition s'étendant à distance des parois en regard de l'élément de structure. Le fait de prévoir un organe de liaison électrique spécifique, dédié uniquement à cette fonction, permet de dissocier celle-ci par rapport à la fonction de fixation mécanique du panneau sur l'ossature. Ceci assure notamment la simplification de la maintenance de la clôture, en particulier d'éventuelles réparations.According to an advantageous embodiment of the invention, the connecting means comprise a connecting member comprising a first mounting zone, in particular of a removable mounting, on a ground or phase plate belonging to a first panel, as well as a second mounting zone, in particular of removable mounting, on a ground or phase plate belonging to a second panel. According to one embodiment of the invention, the connecting member further comprises a transition zone between said mounting zones, this transition zone extending away from the walls facing the structural element. The fact of providing a specific electrical connection member, dedicated solely to this function, allows to dissociate it with respect to the mechanical fastening function of the panel on the frame. This ensures in particular the simplification of the maintenance of the fence, in particular any repairs.

Selon un premier mode de réalisation de l'invention, la zone de transition présente une forme adaptée pour contourner l'élément de structure, notamment une forme de U ou de L. Cette mesure trouve son application, notamment dans le cas où l'élément de structure est un poteau.According to a first embodiment of the invention, the transition zone has a shape adapted to bypass the structural element, in particular a U or L shape. This measure finds its application, particularly in the case where the element of structure is a pole.

Selon un mode de réalisation alternatif de l'invention, l'organe de liaison est une barrette dont la zone de transition traverse une échancrure ménagée dans l'élément de structure. Cette mesure trouve son application, notamment dans le cas où l'élément de structure est une traverse.According to an alternative embodiment of the invention, the connecting member is a bar whose transition zone passes through a recess formed in the structural element. This measure finds its application, especially in the case where the structural element is a cross.

Un autre objet de l'invention est une clôture de sécurité comprenant

  • au moins deux panneaux, chaque panneau comportant au moins une première et une seconde plaques assemblées l'une au voisinage de l'autre, ainsi que des moyens d'isolation électrique entre les deux plaques,

dans laquelle les moyens de liaison comprennent un organe de liaison comportant une première zone de montage, en particulier de montage amovible, sur une plaque de phase ou de masse appartenant à un premier panneau, une seconde zone de montage, en particulier de montage amovible, sur une plaque de phase ou de masse appartenant à un second panneau, ainsi qu'une zone de transition entre ces zones de montage, cette zone de transition s'étendant à distance de l'élément de structure.Another object of the invention is a security fence comprising

  • at least two panels, each panel comprising at least a first and a second assembled plate one in the vicinity of the other, as well as electrical insulation means between the two plates,
  • means for fixing each panel on at least one structural element

in which the connecting means comprise a connecting member comprising a first mounting zone, in particular of a removable mounting, on a phase or mass plate belonging to a first panel, a second mounting zone, in particular removable mounting on a phase plate or mass belonging to a second panel, and a transition zone between these mounting areas, this transition zone extending away from the structural member.

Cette clôture conforme à cet autre objet de l'invention peut comprendre tout ou partie des caractéristiques ci-dessus, dans la mesure où elles sont techniquement compatibles.This enclosure in accordance with this other object of the invention may include all or some of the above features, to the extent that they are technically compatible.

More precisely, there are posts 1, substantially vertical, which are supported by crossbars 2 substantially horizontal.

Cette clôture comprend en outre des panneaux référencés 31 à 39, également de type connu en soi. Chaque panneau comprend deux plaques opposées, s'étendant parallèlement l'une de l'autre. Les figures 3 et 5 illustrent certaines de ces plaques, lesquelles sont référencées respectivement 41, 42 et 44, ainsi que 51, 52 et 54. Comme cela sera explicité dans ce qui suit, les plaques situées d'un premier côté de la clôture sont dites « de masse », alors que celles situées du côté opposé sont dites « de phase ».This fence further comprises panels referenced 31 to 39, also of a type known per se. Each panel has two opposing plates extending parallel to each other. The figures 3 and 5 illustrate some of these plates, which are respectively referenced 41, 42 and 44, as well as 51, 52 and 54. As will be explained in the following, the plates located on one side of the fence are called "mass" , while those on the opposite side are called "live".

Les deux plaques opposées d'un même panneau sont séparées par un isolant électrique 61, 62 et 64 représenté de façon schématique sur les figures 3 et 5, qui est par exemple une couche de colle. Dans l'exemple illustré, chaque plaque présente une structure rigide, tout en étant ajourée. A titre de variante on peut prévoir que ces plaques soient pleines, ou encore qu'elles soient semi-flexibles, voire flexibles. Elles peuvent par exemple être constituées par un treillis métallique.The two opposite plates of the same panel are separated by an electrical insulator 61, 62 and 64 shown schematically on the figures 3 and 5 which is for example a layer of glue. In the illustrated example, each plate has a rigid structure, while being perforated. Alternatively one can predict that these plates are solid, or they are semi-flexible or flexible. They may for example be constituted by a wire mesh.

Les différentes plaques de masse, dont celles 41, 42 et 44, sont reliées électriquement les unes aux autres. A cet effet, il est prévu différents organes de liaison 7 et 8, dont la structure et la fonction seront décrites plus en détail dans ce qui suit. Ces organes sont visibles sur les détails II et IV de la figure 1. Par ailleurs, le circuit de masse constitué par ces plaques est connecté à une masse non représentée, par des moyens de connexion de type connu en soi, qui ne sont pas non plus représentés.The various ground plates, including those 41, 42 and 44, are electrically connected to each other. For this purpose, there are provided various connecting members 7 and 8, the structure and function of which will be described in more detail in the following. These organs are visible on details II and IV of the figure 1 . Furthermore, the ground circuit formed by these plates is connected to a mass not shown, by connection means of a type known per se, which are not represented either.

De manière analogue les différentes plaques de phase, dont celles 51, 52 et 54, sont reliées électriquement les unes aux autres. A cet effet, il est prévu différents organes de liaison 9 et 10, qui ne sont pas visibles sur la figure 1 car ils sont placés sur la face opposée, non visible, de la clôture. La structure et la fonction de ces autres organes 9 et 10 seront décrites plus en détail dans ce qui suit. Par ailleurs, le circuit de phase constitué par ces plaques est connecté à une phase non représentée, par des moyens de connexion de type connu en soi, qui ne sont pas non plus représentés.Similarly, the various phase plates, including those 51, 52 and 54, are electrically connected to one another. For this purpose, different connecting members 9 and 10 are provided, which are not visible on the figure 1 because they are placed on the opposite, not visible, side of the fence. The structure and function of these other organs 9 and 10 will be described in more detail in the following. Moreover, the phase circuit formed by these plates is connected to a phase not shown, by connection means of a type known per se, which are not represented either.

On va maintenant décrire, en référence aux figures 2 et 3, des organes 7 et 9 assurant la liaison électrique entre les plaques de deux panneaux adjacents 31 et 32. Ces panneaux sont fixés sur un poteau 1, par des moyens de type classique qui ne sont pas décrits plus en détail. Chaque organe de liaison 7, en forme de Oméga, présente une âme centrale 71 prolongée par deux ailes 72 et 73, qui sont terminées par des pattes respectives 74 et 75. De façon analogue, chaque organe de liaison 9 présente une âme centrale 91 prolongée par deux ailes 92 et 93, qui sont terminées par des pattes respectives 94 et 95. Les pattes forment des zones, permettant le montage amovible des organes sur deux panneaux adjacents, alors que l'ensemble formé par l'âme et les deux ailes définit une zone de transition entre ces zones de montage.We will now describe, with reference to Figures 2 and 3 , members 7 and 9 providing the electrical connection between the plates of two adjacent panels 31 and 32. These panels are fixed on a pole 1, by means of conventional type which are not described in more detail. Each linkage member 7, Omega-shaped, has a central core 71 extended by two wings 72 and 73, which are terminated by respective tabs 74 and 75. Similarly, each connecting member 9 has a central core 91 extended by two wings 92 and 93, which are terminated by respective tabs 94 and 95. The tabs form zones, allowing the removable assembly of the organs on two adjacent panels, while the assembly formed by the core and the two wings defines a transition zone between these mounting areas.

Comme montré en figure 2, chaque plaque 41 ou 42 est pourvue d'une tige 11 ou 12, pénétrant dans un orifice 74' ou 75' ménagée dans une patte respective 74 ou 75. Deux rondelles 13 ou 14, placées de part et d'autre d'un écrou 15 ou 16, sont intercalées entre les faces en regard de chaque plaque et de chaque patte. Enfin la solidarisation est assurée par un écrou supplémentaire 17 ou 18, notamment de type «indessérable», prévu sur la face opposée de chaque patte.As shown in figure 2 each plate 41 or 42 is provided with a rod 11 or 12, penetrating into an orifice 74 'or 75' formed in a respective tab 74 or 75. Two washers 13 or 14, placed on either side of a nut 15 or 16, are interposed between the facing faces of each plate and each leg. Finally, solidarity is ensured by an additional nut 17 or 18, in particular of the "indessible" type, provided on the opposite face of each leg.

La fixation de l'organe de liaison 9 sur chaque plaque 51 et 52 est réalisée de façon analogue à ce qui vient d'être décrit immédiatement ci-dessus pour l'organe 7. Sur la figure 3 on notera que la fixation des organes 7 et 9 est illustrée de façon schématique, alors que l'épaisseur des pièces mécaniques n'est pas représentée, afin de ne pas surcharger le dessin. L'homme du métier espacera les organes de liaison 7 ou 9 par rapport au poteau 1, selon une distance suffisante pour éviter tout risque de contact intempestif susceptible de provoquer un court-circuit.Fixing the connecting member 9 on each plate 51 and 52 is performed in a manner similar to that just described above for the organ 7. On the figure 3 Note that the attachment of members 7 and 9 is illustrated schematically, while the thickness of mechanical parts is not shown, so as not to overload the drawing. The skilled person will spacing the connecting members 7 or 9 relative to the post 1, at a distance sufficient to avoid any risk of inadvertent contact may cause a short circuit.

Comme le montre plus particulièrement la figure 3, il n'y a pas de recouvrement entre les deux panneaux 31 et 32. En d'autres termes ces derniers ne se superposent pas, lorsqu'ils sont vus selon la flèche F perpendiculaire à leurs plans principaux P31 et P32. Les chants 31' et 32' des panneaux sont distants l'un de l'autre, en étant situés de part et d'autre du poteau de structure 1.As shown more particularly in figure 3 there is no overlap between the two panels 31 and 32. In other words they are not superimposed, when viewed along the arrow F perpendicular to their main planes P31 and P32. The edges 31 'and 32' of the panels are distant from each other, being located on either side of the structural pole 1.

De plus, on notera que ces plans P31 et P32 sont confondus, à savoir que les panneaux sont disposés dans le prolongement l'un de l'autre. Ces plans s'étendent en outre à travers le poteau 1, ce qui permet de conférer une valeur très faible à l'épaisseur locale de la clôture. Cette épaisseur est définie comme la distance, selon la direction de la flèche F, entre les âmes 71 et 91 des organes de liaison 7 et 9.In addition, note that these plans P31 and P32 are confused, namely that the panels are arranged in the extension of one another. These planes further extend through the post 1, which confers a very low value on the local thickness of the fence. This thickness is defined as the distance, in the direction of the arrow F, between the webs 71 and 91 of the connecting members 7 and 9.

On va maintenant décrire, en référence aux figures 4 et 5, d'autres organes 8 et 10 assurant la liaison électrique entre les plaques des deux panneaux adjacents 31 et 34. Ces panneaux sont fixés sur une traverse 2, par des moyens MF de type classique qui sont représentés de façon schématique. Ces moyens de fixation traversent des rebords 41' et 44', ainsi que 51' et 54', formant les chants des panneaux.We will now describe, with reference to Figures 4 and 5 , other members 8 and 10 ensuring the electrical connection between the plates of the two adjacent panels 31 and 34. These panels are fixed on a cross member 2, by MF means of conventional type which are shown schematically. These fixing means pass through flanges 41 'and 44', as well as 51 'and 54', forming the edges of the panels.

Chaque organe de liaison 8 ou 10 présente la forme d'une barrette allongée, dont les deux extrémités sont percées d'orifices. Ces barrettes s'étendent à des travers des passages P8 et P10, qui sont formés par des échancrures ménagées successivement dans les différents rebords et la traverse 2. L'homme du métier espacera les parois en regard des barrettes de liaison, par rapport à celles des rebords et de la traverse, selon une distance suffisante pour éviter tout risque de contact intempestif susceptible de provoquer un court-circuit.Each connecting member 8 or 10 has the shape of an elongate bar, the two ends of which are pierced with orifices. These bars extend through passages P8 and P10, which are formed by indentations formed successively in the different flanges and crossbar 2. The skilled person will spacing the walls opposite the connecting bars, compared to those rims and the crossbar, at a sufficient distance to avoid any risk of inadvertent contact may cause a short circuit.

Comme montré en figure 4, chaque plaque 41 ou 44 est pourvue d'une tige 21 ou 22, pénétrant dans un orifice respectif de la barrette 8. Comme dans le mode de réalisation des figures 2 et 3, deux rondelles placées de part et d'autre d'un écrou sont intercalées entre les faces en regard de chaque plaque et de la barrette. Enfin la solidarisation est assurée par un écrou supplémentaire 27 ou 28, notamment de type « indessérable », prévu sur la face opposée de chaque patte.As shown in figure 4 each plate 41 or 44 is provided with a rod 21 or 22, penetrating into a respective orifice of the bar 8. As in the embodiment of FIGS. Figures 2 and 3 two washers placed on either side of a nut are interposed between the facing faces of each plate and the bar. Finally the securing is provided by an additional nut 27 or 28, particularly of the "indssérable" type, provided on the opposite face of each leg.

La fixation de la barrette 10 sur chaque plaque 51 et 54 est réalisée de façon analogue à ce qui vient d'être décrit immédiatement ci-dessus pour la barrette 8. Comme en figure 3, la fixation des organes de liaison est représentée de façon schématique, afin de ne pas alourdir le dessin. Les deux extrémités longitudinales de chaque barrette forment des zones de montage amovible sur une plaque respective, alors que la région médiane de cette barrette forme une zone de transition entre ces zones de montage.The fixing of the bar 10 on each plate 51 and 54 is performed in a manner similar to that just described above for the bar 8. As in figure 3 , the fastening of the connecting members is shown schematically, so as not to weigh down the drawing. The two longitudinal ends of each bar form removable mounting areas on a respective plate, while the middle region of this bar forms a transition zone between these mounting areas.

Comme le montre plus particulièrement la figure 5, il n'y a pas de recouvrement entre les deux panneaux 31 et 34. En d'autres termes ces derniers ne se superposent pas, lorsqu'ils sont vus selon la flèche F' perpendiculaire à leurs plans principaux P31 et P34. Les chants des panneaux, formés comme vu ci-dessus par les rebords 41', 44', 51' et 54', sont distants l'un de l'autre en étant situés de part et d'autre de la traverse de structure 2.As shown more particularly in figure 5 there is no overlap between the two panels 31 and 34. In other words they are not superimposed, when viewed along the arrow F 'perpendicular to their main planes P31 and P34. The edges of the panels, formed as seen above by the flanges 41 ', 44', 51 'and 54', are spaced apart from each other by being located on either side of the structural cross member 2 .

De plus, on notera que ces plans P31 et P34 sont confondus, à savoir que les panneaux sont disposés dans le prolongement l'un de l'autre. Ces plans s'étendent en outre à travers la traverse 2, ce qui permet de conférer une valeur très faible à l'épaisseur locale de la clôture. Cette épaisseur est définie comme la distance, selon la direction F', entre les faces opposées de la traverse 2.In addition, note that these plans P31 and P34 are confused, namely that the panels are arranged in the extension of one another. These planes further extend through the crossbar 2, which confers a very low value to the local thickness of the fence. This thickness is defined as the distance, in the direction F ', between the opposite faces of the crossbar 2.

L'homme du métier pourra prévoir autant d'organes de liaison que nécessaire entre les plaques, situés d'un même côté de la clôture, afin d'assurer la continuité électrique entre elles. Sur la figure 1, des organes de liaison 7 sont prévus entre les plaques 41 et 42, entre celles 42 et 43, ainsi qu'entre celles 44 et 45. Par ailleurs d organes de liaison 9 sont prévus entre les plaques 41 et 44, entre celles 43 et 46, entre celles 45 et 48, ainsi qu'entre celles 46 et 49. On prévoit bien évidemment des organes complémentaires 8 et 10, entre les plaques opposées non visibles sur la figure 1.The skilled person can provide as many connecting members as necessary between the plates, located on the same side of the fence, to ensure electrical continuity between them. On the figure 1 , connecting members 7 are provided between the plates 41 and 42, between those 42 and 43, and between those 44 and 45. Moreover, connecting members 9 are provided between the plates 41 and 44, between those 43 and 46, between those 45 and 48, as well as between those 46 and 49. Of course, complementary members 8 and 10 are provided between the opposing plates that are not visible on the figure 1 .

La figure 6 illustre une variante de réalisation de l'invention. Sur cette figure 6, les éléments mécaniques analogues à ceux des figures 2 et 3 y sont affectés des mêmes numéros de référence, augmentés de 100.The figure 6 illustrates an alternative embodiment of the invention. On this figure 6 , mechanical elements similar to those of Figures 2 and 3 are assigned the same reference numbers, increased by 100.

La clôture de la figure 6 diffère de celle des figures précédentes, en ce que les deux panneaux adjacents 131 et 132 ne sont pas parallèles, mais perpendiculaires entre eux. Ces panneaux sont fixés sur un poteau 101, par des moyens de type classique qui ne sont pas décrits plus en détail. Chaque organe de liaison 107 présente deux pattes 174 et 175, permettant le montage sur une plaque respective 141 et 142. Cette fixation, qui est illustrée de façon schématique sur cette figure 6, est réalisée de façon analogue à ce qui vient d'être décrit immédiatement ci-dessus pour l'organe 7. Les deux pattes 174 et 175 sont reliées par une zone de transition 171 en forme de L, qui contourne le poteau 101.The closing of the figure 6 differs from that of the preceding figures, in that the two adjacent panels 131 and 132 are not parallel, but perpendicular to each other. These panels are fixed on a pole 101, by means of conventional type which are not described in more detail. Each connecting member 107 has two tabs 174 and 175, allowing mounting on a respective plate 141 and 142. This attachment, which is schematically illustrated on this figure 6 , is carried out analogously to what has just been described immediately above for the member 7. The two lugs 174 and 175 are connected by an L-shaped transition zone 171, which bypasses the pole 101.

On note respectivement P131 et P132 les plans principaux des panneaux 131 et 132. Au sens de l'invention, il n'y a pas de recouvrement entre ces deux panneaux 131 et 132. En d'autres termes ces derniers ne se superposent pas lorsqu'ils sont vus, d'une part selon la flèche F1 perpendiculaire au plan principal P131 et, d'autre part, selon la flèche F2 perpendiculaire au plan principal P132.P131 and P132 respectively denote the main planes of the panels 131 and 132. Within the meaning of the invention, there is no overlap between these two panels 131 and 132. In other words, the latter do not overlap when they are seen, firstly along the arrow F1 perpendicular to the main plane P131 and, secondly, according to the arrow F2 perpendicular to the main plane P132.
