Description

L'invention concerne le domaine technique des clôtures métalliques composées de panneaux fixés à des poteaux.The invention relates to the technical field of metal fencing composed of panels attached to poles.

L'invention concerne plus particulièrement, mais non exclusivement, les clôtures métalliques comprenant des panneaux en treillis de fils, ces panneaux étant accrochés aux poteaux lors de la pose de la clôture, l'accrochage des panneaux aux poteaux étant tel que leur démontage malveillant est difficile.The invention relates more particularly, but not exclusively, to metal fences comprising wire mesh panels, these panels being attached to the posts during the laying of the fence, the attachment of the panels to the posts being such that their malicious disassembly is difficult.

Par « panneaux en treillis » on désigne ici des panneaux à fils tissés ou soudés, métalliques ou non, portant ou non un revêtement décoratif et/ou protecteur, ce revêtement étant métallique ou en matériau polymère.By "lattice panels" is meant here woven or welded son panels, metal or not, with or without a decorative coating and / or protector, this coating being metallic or polymeric material.

Ces panneaux en treillis sont conventionnellement à maille carrée ou rectangulaire et comprennent des fils de chaîne parallèles au sol et des fils de trame sensiblement perpendiculaires aux fils de chaîne.These lattice panels are conventionally square or rectangular mesh and comprise warp son parallel to the ground and weft son substantially perpendicular to the warp son.

On connaît déjà, dans l'art antérieur, différents principes d'association des panneaux de clôtures en treillis sur poteaux.Already known in the prior art, different principles of association of fence panels lattice poles.

Le document FR-A-2.316.414 décrit des poteaux support de treillis, ces poteaux étant pourvus de fentes formant des dents de peigne servant à l'accrochage, à l'appui et au verrouillage des fils de chaîne et de trame du treillis.The document FR-A-2316414 describes lattice support posts, these posts being provided with slots forming comb teeth for hooking, supporting and locking the warp and weft son of the lattice.

Le montage décrit dans le document FR-A-2.316.414 présente de nombreux inconvénients. Par sa conception même, le poteau est inesthétique, une fente verticale et une série de fentes circonférentielles étant apparentes sur la face arrière de la clôture. Cette fente verticale et ces fentes circonférentielles permettent à l'eau de rentrer dans le poteau tubulaire, ce qui pose des problèmes de corrosion et implique, comme précisé dans la description de ce document antérieur, que le poteau soit protégé intérieurement et extérieurement contre la corrosion. La présence des fentes sur la face interne des poteaux de clôture peut entraîner des blessures, en particulier pour les doigts des jeunes enfants. La mise sous tension des panneaux, lors de la pose de la clôture, nécessite, dans le montage du document FR-A-2.316.414 , l'emploi de crochets et d'une clé de serrage, les crochets traversant deux ouvertures radiales ménagées sur chaque poteau. Ces ouvertures radiales sont inesthétiques et leur alignement peut s'avérer imparfait, lorsque les poteaux sont élaborés par pliage. L'emploi d'une clé de serrage pour le rapprochement, via un jeu de crochets amovible, d'un poteau de tension et d'un poteau préscellé s'avère long et fastidieux.The editing described in the document FR-A-2316414 has many disadvantages. By its very design, the post is unsightly, a vertical slot and a series of circumferential slots being apparent on the rear face of the fence. This vertical slot and these circumferential slots allow the water to enter the tubular post, which causes corrosion problems and implies, as specified in the description of this prior document, that the pole is protected internally and externally against corrosion. . The presence of slots on the inside of the fence posts can result in injury, especially to the fingers of young children. Turning on the panels when laying the fence requires, in the assembly of the document FR-A-2316414 , the use of hooks and a wrench, the hooks through two radial openings on each pole. These radial openings are unsightly and their alignment may be imperfect, when the posts are made by folding. The use of a key Tightening for the approximation, via a removable hooks, a tension post and a pre-cabled post is long and tedious.

Le document EP-A-0.288.703 décrit une clôture en treillis dans laquelle des moyens de blocage sont rapportés sur le poteau lors du montage de la clôture. Le montage de la clôture met en oeuvre un grand nombre de pièces détachées et s'avère long et onéreux. La forme des poteaux ne permet pas la réalisation d'angles pour la clôture, sauf à prévoir différents poteaux à rainures en U disposées suivant l'angle souhaité.The document EP-A-0288703 describes a lattice fence in which locking means are attached to the post during assembly of the fence. The assembly of the fence implements a large number of spare parts and is long and expensive. The shape of the columns does not allow the realization of angles for the fence, except to provide different posts with U-shaped grooves arranged at the desired angle.

Le document EP-A-0.443.441 décrit une clôture en treillis dans laquelle les poteaux sont pourvus de deux rainures en U à ouvertures opposées, dans lesquelles les panneaux de grillage sont insérés. Le montage de la clôture implique l'insertion à force de pièces de fixation, ce qui est long et coûteux. La forme des poteaux ne permet pas la réalisation d'angles pour la clôture, sauf à prévoir différents poteaux à rainures en U disposées suivant l'angle souhaité.The document EP-A-0443441 discloses a mesh fence in which the posts are provided with two opposed apertured U grooves into which the grid panels are inserted. The mounting of the fence involves the forced insertion of fasteners, which is long and expensive. The shape of the columns does not allow the realization of angles for the fence, except to provide different posts with U-shaped grooves arranged at the desired angle.

Le document FR-A-2.676.488 décrit un poteau de clôture métallique pour le montage de panneaux en treillis, le montage étant de type peigne, analogue à celui décrit dans le document FR-A-2.316.414 . L'ossature du poteau définit une première partie de section trapézoïdale comprenant une petite base, deux parois latérales inclinées et une grande base disposée en regard des panneaux de clôture en position montée. L'ossature du poteau définit une deuxième partie, prolongeant la première partie, cette deuxième partie étant reliée à la première par une paroi de liaison. Le poteau est réalisé par pliage d'une tôle ou d'un feuillard et présente un plan de symétrie vertical.The document FR-A-2676488 describes a metal fence post for mounting lattice panels, the assembly being of the comb type, similar to that described in the document FR-A-2316414 . The framework of the post defines a first portion of trapezoidal section comprising a small base, two inclined side walls and a large base disposed opposite the fence panels in the mounted position. The frame of the pole defines a second portion, extending the first portion, the second portion being connected to the first by a connecting wall. The post is made by folding a sheet or strip and has a vertical plane of symmetry.

Le poteau décrit dans le document FR-A-2.676.488 présente de nombreux inconvénients. La disposition de rainures, apparentes sur une des faces des poteaux est inesthétique et peut entraîner des blessures, en particulier pour les doigts des jeunes enfants. La jonction entre les parties avant et arrière du poteau est réalisée par un contact plan sur plan de la tôle pliée, d'où des risques de corrosion. La jonction entre les parties avant et arrière du poteau correspond à une grande largeur, rendue nécessaire pour la mise en place de plaques de soubassement P, insérées dans les gorges en U. Du fait de cette grande largeur de l'âme du poteau, les panneaux en treillis sont assez éloignés de la grande base de la première partie, trapézoïdale, du poteau. Il est ainsi possible, ainsi que le déposant l'a constaté, de démonter les panneaux en pliant, à l'aide d'un outil, les rebords des crochets de blocage des fils de trame latéraux des panneaux.The post described in the document FR-A-2676488 has many disadvantages. The provision of grooves, visible on one side of the posts is unsightly and can cause injury, especially for the fingers of young children. The junction between the front and rear portions of the post is made by a plane-to-plane contact of the folded sheet, resulting in the risk of corrosion. The junction between the front and rear portions of the post corresponds to a large width, made necessary for the placement of base plates P, inserted into the U-shaped grooves. Because of this large width of the core of the post, the lattice panels are quite far from the large base of the first part, trapezoidal, of the post. It is thus possible, as well as the depositor found it, disassemble the panels by folding, using a tool, the edges of the locking hooks of the side weft son of the panels.

La clôture décrite dans le document FR-A-2.676.488 s'avère ainsi relativement facile à démonter, pour une personne malveillante.The fence described in the document FR-A-2676488 thus proves relatively easy to disassemble, for an evil person.

L'invention vise à fournir une structure de clôture ne présentant pas les inconvénients de celles connues dans l'art antérieur et permettant, tout à la fois :

  • un montage simple, rapide et peu coûteux des panneaux en treillis sur les poteaux, ce montage ne nécessitant pas de pièces détachées ;
  • une vulnérabilité réduite à l'endommagement et une grande difficulté de démontage malveillant ;
  • une esthétique améliorée et une réduction des risques de corrosion ;
  • une utilisation sans risque pour les écoles et d'une manière générale les lieux dans lesquels des jeunes enfants sont susceptibles de se trouver à proximité des clôtures.
The aim of the invention is to provide a closure structure which does not have the drawbacks of those known in the prior art and which makes it possible at the same time:
  • a simple, fast and inexpensive mounting of the lattice panels on the columns, this assembly does not require any spare parts;
  • a reduced vulnerability to damage and a great difficulty of malicious disassembly;
  • improved aesthetics and reduced risk of corrosion;
  • Safe use for schools and generally places where young children are likely to be near fences.

L'invention vise notamment à fournir une structure de clôture à panneaux assemblés à des poteaux, structure dans laquelle les moyens d'assemblage des panneaux aux poteaux sont tout à la fois masqués à la vue et difficiles d'accès à l'aide d'outils, après montage.The invention aims in particular to provide a fence structure with panels assembled to poles, structure in which the assembly means of the panels to the posts are both hidden from view and difficult to access the help of tools, after assembly.

A ces fins, l'invention se rapporte, selon un premier aspect, à un poteau de clôture profilé creux comprenant, lorsque vu en coupe transversale perpendiculaire à sa direction d'élancement, une première partie A dite avant, une deuxième partie B dite d'accrochage du panneau et une troisième partie C dite arrière, la deuxième partie B comportant deux gorges à ouverture latérale opposées, pourvues d'une rainure bordée latéralement par une cornière formée par le repli sur elle-même de la tôle définissant la paroi de fond des gorges.For these purposes, the invention relates, in a first aspect, to a hollow profiled fence post comprising, when viewed in cross section perpendicular to its direction of slenderness, a first portion A said before, a second portion B said d hooking of the panel and a third portion C said rear, the second part B having two opposite lateral opening grooves, provided with a groove laterally bordered by an angle formed by the folding on itself of the sheet defining the bottom wall throats.

Selon un premier mode de réalisation, la paroi de fond des gorges comprend, d'un bord à l'autre de l'ouverture de la gorge :

  • une première section sensiblement rectiligne ;
  • une deuxième section courbe ;
  • une troisième section, formant ladite cornière, cette troisième section comprenant une première aile, sensiblement perpendiculaire à la deuxième section, et une deuxième aile sensiblement perpendiculaire à la première aile.
According to a first embodiment, the bottom wall of the grooves comprises, from one edge to the other of the opening of the groove:
  • a first substantially rectilinear section;
  • a second curved section;
  • a third section forming said angle, this third section comprising a first wing, substantially perpendicular to the second section, and a second wing substantially perpendicular to the first wing.

Selon un deuxième mode de réalisation, la paroi de fond des gorges comprend d'un bord à l'autre de l'ouverture de la gorge :

  • une première section courbe ;
  • une deuxième section sensiblement rectiligne ;
  • une troisième section en L, formant ladite cornière, cette section en L comprenant une première aile, sensiblement perpendiculaire à la deuxième section, et une deuxième aile, sensiblement perpendiculaire à la première aile.
According to a second embodiment, the bottom wall of the grooves comprises from one edge to the other of the opening of the groove:
  • a first curved section;
  • a second substantially rectilinear section;
  • a third section in L, forming said angle, this L-shaped section comprising a first wing, substantially perpendicular to the second section, and a second wing substantially perpendicular to the first wing.

La formation d'une équerre par repli sur elle-même de la tôle définissant la paroi de fond des gorges confère une rigidité améliorée à cette équerre qui ne peut être facilement pliée à l'aide d'un outil, et ce d'autant que la gorge présente une ouverture réduite laissant peu de place au passage d'outils.The formation of a bracket by folding on itself of the sheet defining the bottom wall of the grooves gives improved rigidity to this bracket which can not be easily bent using a tool, especially as the groove has a reduced opening leaving little room for the passage of tools.

Cette caractéristique présente un avantage certain par rapport au montage décrit dans le brevet FR-A-2.676.488 dans lequel les crochets sont plus accessibles et moins rigides, étant formés par une seule épaisseur de tôle recourbée.This characteristic has a certain advantage over the assembly described in the patent. FR-A-2676488 wherein the hooks are more accessible and less rigid, being formed by a single thickness of curved sheet metal.

Selon une réalisation de l'invention, la première partie du poteau présente, lorsque vue en coupe transversale, une section courbe ou en ligne brisée, concave, joignant les ouvertures des gorges et la troisième partie présente, lorsque vue en coupe transversale, une section en U comprenant une base et deux ailes joignant cette petite base aux troisièmes sections en cornière.According to one embodiment of the invention, the first part of the pole has, when seen in cross section, a curved or broken line in line, concave, joining the openings of the grooves and the third part has, when cross-sectional view, a section U-shaped comprising a base and two wings joining this small base to the third sections in angle.

Suivant diverses réalisations particulières :

  • la base est sensiblement plane et de largeur inférieure à la distance L2 séparant les cornières, les deux ailes de la troisième partie n'étant pas parallèles entre elles ;
  • la largeur L1 de la première partie est supérieure ou sensiblement égale à la distance séparant les cornières ;
  • le poteau présente un plan de symétrie T de part et d'autre duquel s'ouvrent les deux gorges.
According to various particular achievements:
  • the base is substantially flat and of width less than the distance L2 separating the angles, the two wings of the third part not being parallel to each other;
  • the width L1 of the first part is greater than or substantially equal to the distance separating the angles;
  • the post has a plane of symmetry T on both sides of which open the two grooves.

Ces configurations de poteau permettent d'obtenir une module d'inertie élevé et une grande résistance aux chocs.These pole configurations provide a high inertia module and high impact resistance.

Le poteau est, dans une réalisation, élaboré à partir d'une seule tôle ou feuillard plié et soudé bord à bord. Ce mode de réalisation renforce encore la résistance du poteau.The post is, in one embodiment, produced from a single sheet or strip folded and welded edge to edge. This embodiment further strengthens the post strength.

Les troisièmes sections en cornière comprennent des lumières aptes à permettre le passage de fils, notamment fils de chaîne de panneaux de clôture en treillis.The third angled sections include lights capable of allowing the passage of son, including warp fence panel warp son.

L'invention se rapporte, selon un deuxième aspect, aux clôtures formées par assemblage d'au moins un panneau à un poteau tel que présenté ci-dessus.The invention relates, in a second aspect, to fences formed by assembling at least one panel to a post as presented above.

Dans une réalisation, le panneau comprend sur son bord latéral d'assemblage au poteau, un fil de trame venant se loger dans la rainure d'une des gorges du poteau.In one embodiment, the panel comprises on its side edge assembly to the pole, a weft thread being housed in the groove of one of the grooves of the post.

Dans une autre réalisation, le panneau comprend sur son bord latéral d'assemblage du poteau, des fils de chaîne à extrémité recourbées, ces extrémités venant se loger dans la rainure d'une des gorges du poteau.In another embodiment, the panel comprises on its side edge assembly of the pole, warp end warp ends, these ends being housed in the groove of one of the grooves of the post.

On se reporte tout d'abord à la figure 1.We refer first to the figure 1 .

Les traits en tiretés de la figure 1 délimitent, aux fins de la description, trois parties du poteau, à savoir :

  • une première partie A, dite avant ;
  • une deuxième partie B, dite d'accrochage des panneaux de clôture ;
  • une troisième partie C, dite arrière.
The dashed lines of the figure 1 delimit, for the purposes of the description, three parts of the post, namely:
  • a first part A, called before;
  • a second part B, said hooking fence panels;
  • a third part C, called back.

Les termes « avant », « arrière » employés ici pour désigner les parties A et C font référence à une disposition possible du poteau, étant entendu que le poteau peut indifféremment être mis en place avec sa partie A tournée vers l'intérieur ou vers l'extérieur de la parcelle à clôturer.The terms "front" and "rear" used herein to refer to parts A and C refer to a possible disposition of the post, it being understood that the post may be indifferently placed with its part A facing inwards or towards the post. outside the plot to be fenced.

Dans une réalisation préférée, la partie C est celle qui est tournée vers l'espace à partir duquel les chocs sur la clôture sont les plus susceptibles de se produire. Ainsi, par exemple, lorsque la clôture est mise en place en bordure ou à proximité d'une voie routière, la partie C est tournée vers cette voie routière.In a preferred embodiment, part C is the one that is facing the space from which shocks to the fence are most likely to occur. Thus, for example, when the fence is placed along or near a road, part C is turned towards this road.

On décrit tout d'abord la partie B d'accrochage des panneaux. Cette partie B comprend deux gorges 1a, 1b à ouvertures latérales opposées, sensiblement symétriques par rapport à un plan T perpendiculaire au plan de la figure 1. Du fait de cette symétrie, seule la gorge 1 a va être décrite maintenant en détail.Firstly, part B hooking panels. This part B comprises two grooves 1a, 1b with opposite lateral openings, substantially symmetrical with respect to a plane T perpendicular to the plane of the figure 1 . Due to this symmetry, only the groove 1 will now be described in detail.

La gorge 1a est limitée et définie par une paroi comprenant :

  • une première section 2a, sensiblement rectiligne et perpendiculaire au plan T ;
  • une deuxième section 3a, courbe ;
  • une troisième section 4a, en cornière, disposée en regard de la première section 2a.
The groove 1a is limited and defined by a wall comprising:
  • a first section 2a, substantially rectilinear and perpendicular to the plane T;
  • a second section 3a, curved;
  • a third section 4a, angle, disposed opposite the first section 2a.

La troisième section comprend une première aile 5a qui forme un angle de sensiblement 90° avec la deuxième section 3a. De sorte que la deuxième aile 6a de la section 4a délimite, avec la première aile 5a et la deuxième section 3a, une rainure 7a de section en U.The third section comprises a first wing 5a which forms an angle of substantially 90 ° with the second section 3a. So that the second wing 6a of the section 4a delimits, with the first wing 5a and the second section 3a, a groove 7a of U section.

La première et la deuxième section 2a, 3a de la gorge 1a peuvent être obtenues par pliage d'une tôle. Ainsi qu'il apparaît en figure 1, cette tôle est repliée sur elle même pour former la troisième section 4a en cornière, de sorte que cette section en cornière présente une épaisseur de tôle doublée.The first and second sections 2a, 3a of the groove 1a can be obtained by folding a sheet. As it appears in figure 1 this sheet is folded on itself to form the third section 4a angle, so that this angle section has a doubled sheet thickness.

On décrit maintenant la première partie A et la troisième partie C du poteau.We now describe the first part A and the third part C of the post.

La première partie A présente, dans le mode de réalisation de la figure, une section concave en arc de cercle 8. Il est entendu que d'autres sections pourraient être employées, notamment en arc d'ellipse, en ligne brisée, en arc de cercle avec méplat.The first part A presents, in the embodiment of the figure, a concave section in a circular arc 8. It is understood that other sections could be used, in particular in elliptical arc, broken line, arc of circle with flat.

La troisième partie C présente, dans le mode de réalisation de la figure 1, une section trapézoïdale avec :

  • une petite base 9 ;
  • deux parois latérales 10a, 10b reliant cette petite base aux premières ailes 5a, 5b des sections 4a, 4b en cornière.
Part Three C presents, in the embodiment of the figure 1 , a trapezoidal section with:
  • a small base 9;
  • two side walls 10a, 10b connecting this small base to the first wings 5a, 5b sections 4a, 4b angle.

Les parois latérales 10a, 10b sont sensiblement alignées aux premières ailes 5a, 5b des sections 4a, 4b.The side walls 10a, 10b are substantially aligned with the first wings 5a, 5b of the sections 4a, 4b.

Il est entendu que la troisième partie C pourrait présenter une section différente d'un trapèze, par exemple, une section en arc de cercle, arc d'ellipse, ligne brisée ou arc de cercle avec méplat.It is understood that the third part C could have a different section of a trapezium, for example, a section in an arc, elliptical arc, broken line or arc with flat.

La largeur L1 de la première partie A, mesurée perpendiculairement au plant T, est supérieure ou sensiblement égale à la distance L2 séparant les sections en cornière 4a.The width L1 of the first portion A, measured perpendicularly to the plant T, is greater than or substantially equal to the distance L2 between the bracketed sections 4a.

Ainsi qu'il apparaîtra plus complètement par la suite, cette disposition permet d'escamoter les moyens d'assemblage des panneaux aux poteaux pour un observateur regardant la clôture du coté de la partie A. Cette disposition assure également un blocage des panneaux de clôture contre les poteaux, en cas d'angle rentrant pour la clôture (position en tirets pour le panneau, en figure 8) .As will appear more completely later, this provision allows to retract the means of assembly of the panels to the posts for an observer looking at the fence on the side of the part A. This provision ensures also a blocking of the fence panels against the posts, in case of re-entrant angle for the fence (dashed position for the panel, in figure 8 ).

L'ensemble du poteau présente un plan de symétrie par rapport au plan T défini précédemment.The whole of the post has a plane of symmetry with respect to the plane T defined previously.

Si la configuration représentée en figure 1 permet d'obtenir un moment d'inertie élevé et une esthétique agréable, l'homme du métier est en mesure de définir d'autres formes pour les parties A et C sans pour autant sortir du champ de protection de l'invention.If the configuration represented in figure 1 allows to obtain a high moment of inertia and aesthetic pleasing, the skilled person is able to define other forms for parts A and C without departing from the scope of the invention.

Les angles de courbure du poteau sont arrondis, le poteau étant dépourvu d'arêtes saillantes susceptibles d'être dangereuses. Les bords libres des cornières 4a ne sont pas accessibles, tant pour les doigts des jeunes enfants que pour un outil, ce qui renforce la sécurité de la clôture.The angles of curvature of the post are rounded, the post being devoid of salient edges likely to be dangerous. The free edges of the brackets 4a are not accessible, both for the fingers of young children than for a tool, which enhances the security of the fence.

Ainsi qu'il est représenté en figure 1, le poteau est obtenu, dans un mode de réalisation, par pliage d'une tôle soudée bord à bord, le cordon de soudure étant par exemple disposé sur la section 8 et s'étendant sensiblement suivant le plan T.As it is represented in figure 1 , the pole is obtained, in one embodiment, by folding a sheet welded edge to edge, the weld bead being for example disposed on the section 8 and extending substantially along the plane T.

Dans d'autres modes de réalisation, les bords de la tôle pliée sont assemblés par agrafage, rivetage ou tout autre procédé équivalent.In other embodiments, the edges of the folded sheet are assembled by stapling, riveting, or any other equivalent method.

Dans d'autres modes de réalisation, le poteau est obtenu par assemblage d'au moins deux éléments, cet assemblage étant obtenu par soudage, rivetage, boulonnage, encliquetage, ou tout autre moyen équivalent.In other embodiments, the post is obtained by assembling at least two elements, this assembly being obtained by welding, riveting, bolting, latching, or any other equivalent means.

Ainsi, par exemple, la première partie A et la deuxième partie B peuvent être pourvues de moyens d'assemblage complémentaires, de sorte que plusieurs formes de parties A peuvent être assemblées, au choix, en face avant du poteau, permettant à l'utilisateur d'obtenir différentes esthétiques pour le poteau.Thus, for example, the first part A and the second part B may be provided with complementary assembly means, so that several shapes of parts A may be assembled, as desired, on the front face of the post, allowing the user to obtain different aesthetics for the pole.

De même, la troisième partie C et la deuxième partie B peuvent être pourvues de moyens d'assemblage complémentaires, plusieurs esthétiques de poteau pouvant être ainsi obtenues.Similarly, the third part C and the second part B may be provided with complementary assembly means, several pole aesthetics can be obtained.

On se reporte maintenant à la figure 2.We are now going back to figure 2 .

Le poteau représenté en figure 2 est semblable à celui représenté en figure 1 pour un rapport d'épaisseur/largeur différent, la largeur L1 de la partie A étant en outre inférieure à la distance L2 séparant les cornières 4a, 4b.The pole represented in figure 2 is similar to the one represented in figure 1 for a different thickness / width ratio, the width L1 of the part A being furthermore less than the distance L2 separating the angles 4a, 4b.

Le tableau 2 suivant donne, à titre indicatif, les valeurs des caractéristiques mécaniques mentionnées au tableau 1, pour un poteau conforme à la figure 2, obtenu par pliage d'une tôle d'acier d'épaisseur 0,98 mm, le poteau étant de largeur L2 égale à 52,18 mm et de profondeur E égale à 69,58 mm.

La comparaison des tableaux 1 et 2 illustre nettement les avantages du dimensionnement de la figure 1, en termes de résistance mécanique. Le mode de réalisation de la figure 2 pourra être employé pour des clôtures plus légères et moins exposées aux chocs.The comparison of Tables 1 and 2 clearly illustrates the advantages of sizing the figure 1 in terms of mechanical strength. The embodiment of the figure 2 can be used for fences lighter and less exposed to shocks.

On se reporte maintenant à la figure 3.We are now going back to figure 3 .

Le poteau vu en coupe en figure 3 est semblable à celui de la figure 1, sauf pour ce qui est de la forme des gorges 1a, 1b.The post seen in section in figure 3 is similar to that of the figure 1 , except for the shape of the grooves 1a, 1b.

En effet, ces gorges 1a,1b sont définies et limitées par une paroi comprenant, d'un bord à l'autre de l'ouverture de la gorge :

  • une première section, courbe 20a, 20b ;
  • une deuxième section, sensiblement rectiligne 21a, 21b et perpendiculaire au plan T ;
  • une troisième section en cornière 22a, 22b comprenant une première aile 23a, 23b sensiblement parallèle au plan T et une deuxième aile 24a, 24b sensiblement perpendiculaire au plan T.
Indeed, these grooves 1a, 1b are defined and limited by a wall comprising, from one edge to the other of the opening of the groove:
  • a first section, curve 20a, 20b;
  • a second substantially rectilinear section 21a, 21b and perpendicular to the plane T;
  • a third angle section 22a, 22b comprising a first flange 23a, 23b substantially parallel to the plane T and a second flange 24a, 24b substantially perpendicular to the plane T.

La première aile 23a, 23b, la deuxième aile 24a, 24b et la deuxième section 21 a, 21 b délimitent une rainure 25a, 25b de section en U à ouverture tournée vers la section courbe 20a, 20b.The first wing 23a, 23b, the second wing 24a, 24b and the second section 21a, 21b delimit a groove 25a, 25b of U-shaped section opening towards the curved section 20a, 20b.

On se reporte maintenant aux figures 4 à 8 qui illustrent la mise en place d'un panneau sur une poteau.We now turn to Figures 4 to 8 which illustrate the setting up of a panel on a pole.

Les panneaux représentés en figures 4 à 7 sont du type treillis de fils, tels que définis précédemment. Ils comportent des fils de chaîne 30 et des fils de trame 31, disposés suivant une maille rectangulaire dans les modes de réalisation représentés.The panels represented in Figures 4 to 7 are of the wire mesh type, as defined above. They comprise warp son 30 and weft son 31, arranged in a rectangular mesh in the embodiments shown.

Dans le mode de réalisation de la figure 4, le panneau comporte un fil de trame latéral extrême 32 venant s'insérer, lors du montage de la clôture dans la rainure 7a, 7b du poteau représenté en figure 1.In the embodiment of the figure 4 , the panel comprises an extreme lateral weft thread 32 which is inserted during the assembly of the fence in the groove 7a, 7b of the post shown in FIG. figure 1 .

A cette fin, la troisième section 4a, 4b en cornière est pourvue de lumières 33 dont l'ouverture L3, mesurée suivant la direction d'élancement du poteau, est supérieure au diamètre D1 des fils de chaîne 30.To this end, the third section 4a, 4b angle is provided with lights 33 whose opening L3, measured in the direction of slenderness of the pole, is greater than the diameter D1 of the warp son 30.

Par exemple, cette ouverture L3 est comprises entre 5,5 mm et 7 mm pour permettre l'utilisation de panneaux en treillis réalisés avec du fil de 4 mm ou 5 mm.For example, this opening L3 is between 5.5 mm and 7 mm to allow the use of lattice panels made with 4 mm or 5 mm wire.

Bien entendu, le nombre, la répartition et l'ouverture des lumières 33 peut être adaptée, ainsi que saura l'établir l'homme du métier, pour différents diamètres de fils de treillis, différentes dimensions et formes de maille de treillis.Of course, the number, distribution and opening of the lights 33 can be adapted, as will be established by those skilled in the art, for different diameters of lattice son, different sizes and lattice mesh shapes.

Dans les modes de réalisation représentés, les lumières 33 sont sensiblement identiques et équidistantes. Dans d'autres modes de réalisation, les lumières ne sont pas équidistantes, pour permettre la mise en place d'un treillis comportant une densité de fils de chaîne plus grande sur une section, par exemple inférieure, du panneau. Dans d'autres modes de réalisation, les lumières ne sont pas d'ouvertures identiques, pour permettre la mise en place d'un treillis comportant des fils de trame de diamètres différents, par exemple plus gros en partie inférieure du panneau.In the embodiments shown, the lights 33 are substantially identical and equidistant. In other embodiments, the lights are not equidistant, to allow the establishment of a mesh having a higher density of warp son on a section, for example lower, of the panel. In other embodiments, the lights are not identical openings, to allow the establishment of a lattice having weft son of different diameters, for example larger in the lower part of the panel.

Dans le mode de réalisation de la figure 5, ce n'est pas un fil de trame latéral du panneau qui est mis en place dans une rainure 7a, 7b, 25a, 25b du poteau, mais les extrémités recourbées à 90° des fils de chaîne du panneau.In the embodiment of the figure 5 it is not a lateral weft yarn of the panel which is set up in a groove 7a, 7b, 25a, 25b of the post, but the ends curved at 90 ° of the warp threads of the panel.

Ces extrémités recourbées 34 des fils de chaîne, ou coudes d'accrochage peuvent s'étendre vers le haut ou vers le bas du panneau. Il va de soi que les coudes d'accrochage peuvent être disposés sur tous les fils de chaîne du panneau ou sur seulement une partie de ceux-ci.These bent ends 34 of the warp yarns, or bends of attachment can extend upwards or downwards of the panel. It goes without saying that Elbow bends may be provided on all or part of the warp threads of the panel.

Les portions de fils formant coude d'accrochage peuvent être obtenues par pliage des fils de chaîne.The son portions forming hooking elbow can be obtained by folding the warp son.

Bien que le panneau pourvu de fils de chaîne recourbés soit représenté en figure 5 pour son montage avec le poteau dessiné en figure 3, il est entendu toutefois que ce panneau pourrait être monté sur un poteau du type de la figure 1.Although the panel provided with bent warp wires is shown in FIG. figure 5 for its mounting with the post drawn in figure 3 , it is understood however that this panel could be mounted on a pole of the type of the figure 1 .

De même, le panneau représenté en figure 4 pourrait être monté sur un poteau du type de la figure 3.Similarly, the panel represented in figure 4 could be mounted on a pole of the type of the figure 3 .

Ainsi qu'il apparaît en figures 4 à 7, il n'est pas nécessaire que tous les fils de chaîne soient logés, à leur extrémité latérale, au travers d'une lumière 33 du poteau. De sorte que le panneau peut comporter des fils de trames pourvus d'ondulations dans des plans parallèles au plan de symétrie T du poteau. Une ondulation 35 est représentée sur les figures 4 à 7. Cette ondulation pourrait être placée plus haut ou plus bas sur le panneau. Le panneau pourrait comporter deux ou plus de deux ondulations, du type représenté.As it appears in Figures 4 to 7 it is not necessary that all the warp son are housed, at their lateral end, through a light 33 of the pole. So that the panel may comprise son of frames provided with corrugations in planes parallel to the plane of symmetry T of the pole. A corrugation 35 is shown on the Figures 4 to 7 . This ripple could be placed higher or lower on the panel. The panel could have two or more corrugations of the type shown.

On se reporte maintenant à la figure 8.We are now going back to figure 8 .

L'ouverture e des gorges 1a, 1b est réduite, sensiblement de l'ordre de deux fois la largeur I de la rainure 7a, 7b dans laquelle vient se loger le bord latéral du panneau.The opening e grooves 1a, 1b is reduced, substantially of the order of twice the width I of the groove 7a, 7b in which is housed the side edge of the panel.

Cette disposition permet de limiter les risques de démontage malveillant. En effet :

  • en premier lieu, le bord extrême libre 35 des cornières est rendu moins accessible, car placé à l'intérieur d'une gorge d'ouverture e réduite ;
  • à supposer qu'un opérateur malveillant parvienne à tordre la double épaisseur de tôle de chacun des bras des cornières, réduisant ainsi l'ouverture e, il lui sera difficile de faire sortir le bord du panneau de la gorge dont il a refermé l'ouverture.
This provision makes it possible to limit the risks of malicious disassembly. Indeed :
  • firstly, the free end edge 35 of the angles is made less accessible, because placed inside a groove opening e reduced;
  • assuming that a malicious operator is able to twist the double sheet thickness of each of the angle arms, reducing the opening e, it will be difficult for him to pull the edge of the panel of the groove which he closed the opening .

Le poteau selon l'invention présente d'autres avantages.The pole according to the invention has other advantages.

La pose des panneaux peut être effectuée rapidement et facilement et ce, sans accessoire. Le poteau présente une grande résistance aux chocs et une inertie élevée.The panels can be installed quickly and easily and without any accessories. The post has high impact resistance and high inertia.

L'esthétique de la clôture est améliorée, par rapport aux montages antérieurs, notamment parce que les panneaux peuvent être accrochés sensiblement à mi distance entre les bords avant et arrière du poteau.The aesthetics of the fence is improved, compared to previous fixtures, in particular because the panels can be hung substantially midway between the front and rear edges of the pole.

Les risques de blessures sont éliminés, pour les jeunes enfants, le poteau ne comportant pas d'angles vifs et les lumières 33 étant peu accessibles.The risk of injury is eliminated for young children, the pole has no sharp corners and the lights 33 are inaccessible.

Il est possible de réaliser des clôtures avec des angles rentrants ou sortants. L'angle . de la figure 8 illustre le secteur angulaire rentrant accessible à l'aide d'un poteau conforme à la figure 1.It is possible to make fences with incoming or outgoing angles. The angle. of the figure 8 illustrates the incoming re-entrant angular sector using a pole conforming to the figure 1 .

Le poteau selon l'invention peut être employé comme poteau d'angle, les panneaux fixés de part et d'autre de ce poteau d'angle étant sensiblement à 90 ° l'un de l'autre.The post according to the invention can be used as an angle post, the panels fixed on either side of this corner post being substantially at 90 ° to each other.

Un choc éventuel sur un panneau de clôture, du coté extérieur, ne peut pas provoquer son décrochage.A possible impact on a fence panel, on the outer side, can not cause its stall.

Les lumières d'accrochage se débouchant pas à l'intérieur du profilé fermé du poteau, ce poteau présente une étanchéité renforcée améliorant sa résistance à l'environnement. Un cache en polymère ou tout autre matériau peut être monté, par exemple par encliquetage, en partie haute du poteau, ainsi qu'il est connu en soi.The hanging lights not opening inside the closed section of the post, this post has a reinforced seal improving its resistance to the environment. A cover in polymer or any other material may be mounted, for example by snapping, in the upper part of the pole, as is known per se.

Le profilé peut être réalisé en acier inoxydable ou en acier galvanisé, par exemple d'épaisseur inférieure à 2 mm, notamment voisine de 1,2 mm.The profile can be made of stainless steel or galvanized steel, for example less than 2 mm thick, especially close to 1.2 mm.

On décrit maintenant un moyen de réparation d'un poteau selon l'invention, en référence à la figure 9.We now describe a pole repair means according to the invention, with reference to the figure 9 .

Le poteau de réparation peut être mis en place lorsque la clôture a subi un choc sur sa face avant ou arrière, par exemple lorsqu'un véhicule a plié la clôture.The repair pole can be put in place when the fence has been hit on its front or rear side, for example when a vehicle has folded the fence.

La mise en place du poteau de réparation s'effectue de la manière suivante :

  • dans une première étape, le poteau endommagé est scié à sa base ;
  • les panneaux qui étaient montés sur le poteau endommagé étant généralement eux mêmes endommagés, l'opérateur les remplace par des panneaux neufs ;
  • une première partie 40 de poteau de remplacement est mise en place et scellée à l'emplacement du poteau endommagé. Cette première partie 40 forme le corps principal du poteau de remplacement et se présente sous la forme d'un profilé ouvert, correspondant à un poteau tel que représenté en figures 1 à 3, coupé selon un plan P1 vertical perpendiculaire au plan T, ce plan P1 s'étendant dans la section B d'assemblage ;
  • la première partie 40 est écartée suivant les flèches F1 de sorte à permettre la mise en place des panneaux dans les cornières ;
  • puis, par exemple, à l'aide d'un serre-joint, la première partie 40 est resserrée suivant les flèches F2 de sorte à permettre le coulissement d'une seconde partie 41 du poteau de remplacement. Cette seconde partie 41 forme le corps complémentaire du poteau de remplacement et se présente sous la forme d'un profilé ouvert correspondant à un poteau tel que représenté en figure 1 à 3, coupé suivant un plan P2 vertical perpendiculaire au plan T, ce plan P2 étant parallèle et distant au plan P1 défini précédemment et s'étendant dans la section B d'assemblage.
The installation of the repair pole is carried out as follows:
  • in a first step, the damaged post is sawn at its base;
  • the panels which were mounted on the damaged post being generally themselves damaged, the operator replaces them with new panels;
  • a first portion 40 of replacement pole is put in place and sealed at the location of the damaged pole. This first part 40 forms the main body of the replacement pole and presents itself in the form of an open profile corresponding to a pole as shown in FIG. Figures 1 to 3 , cut along a vertical plane P1 perpendicular to the plane T, this plane P1 extending in the assembly section B;
  • the first portion 40 is spaced along the arrows F1 so as to allow the establishment of the panels in the angles;
  • then, for example, using a clamp, the first portion 40 is constricted according to the arrows F2 so as to allow the sliding of a second portion 41 of the replacement pole. This second portion 41 forms the complementary body of the replacement pole and is in the form of an open profile corresponding to a pole as shown in FIG. figure 1 to 3 , cut along a vertical plane P2 perpendicular to the plane T, this plane P2 being parallel and distant to the plane P1 defined above and extending into the assembly section B.

Un cache en matériau polymère 42 ou tout autre matériau est ensuite monté, par exemple par encliquetage, en partie haute du poteau de remplacement.A cover of polymer material 42 or any other material is then mounted, for example by snapping, in the upper part of the replacement pole.

La figure 10 représente le poteau de remplacement, dans trois états successifs de montage, vus en coupe transversale.The figure 10 represents the replacement pole, in three successive states of assembly, seen in cross section.

Dans un premier état (figure 10a), les panneaux de clôtures sont mis en place sur le corps principal 40, par écartement, selon les flèches F1, des ailes 10a, 10b du corps principal du poteau de remplacement. Cet écartement est nécessaire dans la mesure où la largeur des panneaux, sensiblement indéformables, est inférieure à la distance séparant leurs cornières de montage, les clôtures étant montées à l'avancement.In a first state ( figure 10a ), the fencing panels are placed on the main body 40, by spacing, according to the arrows F1, wings 10a, 10b of the main body of the replacement pole. This spacing is necessary insofar as the width of the panels, substantially indeformable, is less than the distance between their mounting angles, the fences being mounted in progress.

Dans une deuxième état (figure 10b), les sections courbes 2a, 2b du corps principal du poteau de remplacement sont rapprochées, par exemple à l'aide d'un serre-joint 43 et le corps complémentaire 41 est coulissé sur les sections courbes 2a, 2b.In a second state ( figure 10b ), the curved sections 2a, 2b of the main body of the replacement pole are brought together, for example by means of a clamp 43 and the complementary body 41 is slid on the curved sections 2a, 2b.

Dans un troisième état final (figure 10c) les sections courbes chevauchantes 2a, 2b du corps principal et du corps complémentaire sont plaquées l'une contre l'autre.In a third final state ( figure 10c ) the overlapping curved sections 2a, 2b of the main body and the complementary body are pressed against each other.

La mise en place du poteau de remplacement est peu ou pas décelable, la zone de jonction entre corps principal 40 et corps complémentaire 41 étant placée au creux des gorges 1 a, 1 b.The establishment of the replacement pole is little or not detectable, the junction zone between the main body 40 and the complementary body 41 being placed in the hollow of the grooves 1 a, 1 b.

L'étendue de cette zone de chevauchement entre corps principal et corps complémentaire 40, 41 est définie par la distance séparant les plans P1 et P2 définis précédemment. Pour les besoins de la description, les plans P1 et P2 sont définis en référence à deux poteaux complets qui seraient découpés. Il est entendu que les corps complémentaires et corps principaux 40, 41 des poteaux de réparation sont de préférence élaborés par découpage de deux poteaux distincts.The extent of this zone of overlap between the main body and the complementary body 40, 41 is defined by the distance separating the planes P1 and P2 defined previously. For the purposes of the description, planes P1 and P2 are defined with reference to two complete posts that would be cut. It is understood that the complementary bodies and main bodies 40, 41 of the repair columns are preferably produced by cutting two separate columns.

Il est à noter que l'assemblage du poteau de réparation est rendu possible par la forme creuse du profilé, dans sa zone de jonction 44 entre face avant et face arrière du poteau.It should be noted that the assembly of the repair pole is made possible by the hollow form of the profile, in its junction zone 44 between the front face and rear face of the pole.

On se reporte maintenant à la figure 11.We are now going back to figure 11 .

Une pièce 50 à section en C peut être introduite dans les gorges du poteau, par insertion dans les cornières 4a, 4b, 22a, 22b.A C-section piece 50 may be introduced into the grooves of the post, by insertion into the angles 4a, 4b, 22a, 22b.

Cette pièce 50 forme glissière pour l'introduction et le maintien de panneaux pleins 51, par exemple en béton ou en bois, ces panneaux étant par exemple déposés en dessous de panneaux treillis.This piece 50 form slider for the introduction and maintenance of solid panels 51, for example concrete or wood, these panels being for example deposited below lattice panels.

Ce type de montage permet, contrairement au montage décrit dans le document FR-A-2.676.488 , de placer des plaques de soubassement sensiblement dans le même plan que les panneaux en treillis accrochés aux poteaux.This type of assembly allows, unlike the assembly described in the document FR-A-2676488 , to place basement plates substantially in the same plane as the lattice panels hung on the posts.

La clôture ainsi obtenue est plus esthétique.The fence thus obtained is more aesthetic.
