Description

La présente invention concerne un organe de fixation d'un grillage de clôture sur un poteau ou piquet, traditionnellement mis en oeuvre pour ériger une telle clôture. Elle se rapporte également à une clôture mise en place au moyen de tels organes.The present invention relates to a fastening member of a fence fence on a post or post, traditionally used to erect such a fence. It also refers to a fence put in place by means of such bodies.

Un grand nombre de clôtures est réalisé à partir d'un grillage, souple ou rigide, fixé sur une pluralité de poteaux ou piquets de clôture, sensiblement périodiquement répartis et érigés le long du périmètre à clôturer. Ces poteaux ou piquets de clôture peuvent, par exemple, être constitués de profilés métallique en section transversale en forme de T ou de L. Le grillage mis en oeuvre peut être un grillage souple, à simple, double ou triple torsion, formé à partir de fils, généralement métalliques, de maille carrée, rectangulaire ou encore en forme de losange. Le choix de la combinaison de la maille, du diamètre du fil et du mode de torsion dépend de la solidité recherchée. Un deuxième type de grillage, rigide cette fois, est formé à partir de treillis métalliques soudés, de maille rectangulaire.A large number of fences are made from a grid, flexible or rigid, fixed on a plurality of posts or fence posts, substantially periodically distributed and erected along the perimeter to be fenced. These posts or fence stakes may, for example, consist of metal sections in T or L-shaped cross-section. The mesh used may be a flexible grid, with single, double or triple torsion, formed from threads, generally of metal, of square, rectangular or diamond-shaped mesh. The choice of the combination of the mesh, the diameter of the wire and the mode of torsion depends on the required solidity. A second type of grid, rigid this time, is formed from welded wire mesh, rectangular mesh.

De manière classique, les grillages souples supposent la mise en place préalable d'un ou de plusieurs fils de tension munis de tendeur, s'étendant sensiblement horizontalement entre les différents poteaux précités. Ces fils de tension sont notamment susceptibles d'être reçus au niveau de chacun desdits poteaux au sein d'un orifice traversant.Conventionally, the flexible screens assume the prior establishment of one or more tension son provided with tensioner, extending substantially horizontally between the various aforementioned columns. These tension son are particularly likely to be received at each of said posts in a through hole.

Les grillages de type rigide sont, quant à eux, généralement fixés auxdits poteaux au moyen d'une agrafe ou d'un collier venant enserrer l'un des fils qui les constituent avec lesdits poteaux.The rigid type of screens are, in turn, generally attached to said posts by means of a clip or a collar from gripping one of the son that constitute them with said poles.

On connaît d'après le document EP - A - 0.481.100 une bride de serrage venant se positionner sur la pointe d'un piquet de clôture sensiblement triangulaire. Des orifices sont ménagés au niveau de la pointe, afin de permettre le maintien de cette bride par vissage sur le piquet.We know from the document EP - A - 0.481.100 a clamping flange being positioned on the tip of a fence rod substantially triangular. Orifices are provided at the tip, to allow the maintenance of this flange by screwing on the stake.

Cependant, cette fixation à bride ne permet qu'un réglage en hauteur par pas successifs discrets, en suivant les orifices. De plus, cette fixation n'est prévue que pour l'attache de fils de tensions sur lesquels est solidarisé le grillage proprement dit.However, this flange mount allows only a height adjustment in successive discrete steps, following the orifices. In addition, this attachment is provided for the attachment of tension son on which is secured the actual wire mesh.

On connaît également d'après le document US - A - 5.676.351 un système de fixation d'un grillage à un piquet, mettant en oeuvre un organe venant s'encliqueter dans un orifice ménagé dans le piquet. L'organe comprend deux pattes latérales venant maintenir par plaquage un ou plusieurs fils du grillage contre une zone plane du piquet.
L'inconvénient de ce système réside dans le fait qu'il ne peut y avoir de réglage précis en hauteur. En outre, le réglage susceptible d'être obtenu est discret, car imposé par le nombre d'orifices et par l'écartement entre eux. De plus, ce système de fixation par coincement ne semble pas fiable, des coulissements entre les pattes de l'organe et le ou les fils du grillage pouvant survenir.It is also known from the document US - A - 5,676,351 a system for fixing a fence to a stake, implementing a member that snaps into an orifice in the stake. The member comprises two lateral tabs which maintain by plating one or more son of the mesh against a flat area of the stake.
The disadvantage of this system lies in the fact that there can be no precise adjustment in height. In addition, the adjustment that can be obtained is discrete, because imposed by the number of orifices and the spacing between them. In addition, this fixing system by wedging does not seem reliable, slippage between the legs of the body and the son or son of the grill may occur.

On connaît d'après les documents FR - A - 2.686.640 ou DE - A - 34.22.049 une agrafe venant se fixer à une hauteur souhaitée sur le profilé d'un montant. Cette agrafe est destinée à permettre une insertion de fils maintenus sous tension appartenant à des grillages traditionnels. Les fils sont ainsi maintenus en étant plaqué contre une face du montant.
Cependant, ce système de fixation à agrafe ne permet que la solidarisation du fil et non pas d'un grillage. En outre, ce système n'est pas autobloquant, à la fois par rapport au poteau et par rapport au fil. En effet, en cas de fortes contraintes, cette agrafe peut se déplacer le long du poteau et le fil peut également coulisser sous l'agrafe. Enfin, en raison des frottements directs, ce système conduit à l'usure ou à des phénomènes d'oxydation locaux du fil, de l'agrafe et du poteau.We know from the documents FR - A - 2.686.640 or DE-A-34.22.049 a clip that attaches to a desired height on the profile of an upright. This clip is intended to allow insertion of son kept under tension belonging to traditional screens. The son are thus maintained by being pressed against one side of the amount.
However, this clip fastening system only allows the securing of the wire and not a grid. In addition, this system is not self-locking, both with respect to the post and relative to the wire. Indeed, in case of heavy stress, this clip can move along the pole and the wire can also slide under the clip. Finally, because of the direct friction, this system leads to wear or local oxidation phenomena of the wire, the staple and the post.

Enfin, on a décrit dans le document WO 03/040496 un dispositif de fixation limitativement dédié à un poteau à section transversale triangulaire, et donc nécessitant autant de système que de tailles de poteau.Finally, we described in the document WO 03/040496 a fastening device that is limited to a post with a triangular cross-section, and therefore requires as much system as post sizes.

Un premier objectif que se propose d'atteindre l'invention est d'obtenir un organe de pose et de fixation d'un grillage, susceptible de s'adapter à tous les types de grillages et à tous les types de montants ou poteaux.A first objective that the invention proposes to achieve is to obtain a member for installing and fixing a screen, capable of adapting to all types of screens and all types of posts or posts.

Un second objectif que vise à atteindre l'invention réside dans la réalisation d'un organe de pose et de fixation du grillage, susceptible d'autoriser facilement le réglage en hauteur du grillage par rapport au piquet.A second objective that aims to achieve the invention lies in the realization of a member for laying and fixing the mesh, which can easily allow the height adjustment of the mesh relative to the stake.

Un troisième objectif visé par la présente invention réside dans la mise au point d'un organe de fixation qui n'endommage ni le fil du grillage, ni le montant ou piquet sur lequel est fixé le grillage.A third objective of the present invention lies in the development of a fastener which does not damage the wire of the grid, or the amount or stake on which is fixed the grid.

Un quatrième objectif visé par la présente invention réside dans le montage rapide d'une clôture avec un grillage fixé à des piquets ou poteaux de clôture, et susceptible de s'adapter à toutes les configurations rencontrées sur le terrain.A fourth objective of the present invention is the rapid assembly of a fence with a fence attached to posts or fence posts, and adapted to all configurations encountered in the field.

Conformément à un premier aspect de l'invention, l'organe de fixation d'un grillage de clôture sur un poteau réalisé selon un profilé à section transversale en forme de T, comprend :

  • un premier élément apte à s'encliqueter sur le profilé constitutif dudit poteau et présentant au moins un logement destiné à recevoir l'un des fils entrant dans la constitution du grillage ou participant à sa fixation, et
  • un deuxième élément formant couvercle, destiné à coopérer avec ledit premier élément, et venant fermer le logement de ce dernier de telle sorte à maintenir ledit fil entrant dans la constitution du grillage ou participant à sa fixation au sein de ce logement.
According to a first aspect of the invention, the fastening member of a fence fence on a post made of a T-shaped cross section profile comprises:
  • a first element adapted to snap onto the constituent section of said post and having at least one housing for receiving one of the wires forming part of the grid or participating in its fixing, and
  • a second cover member for cooperating with said first member and closing the housing thereof so as to maintain said wire entering the structure of the mesh or participating in its fixing within the housing.

Autrement dit, l'invention permet, au moyen dudit premier élément, de réaliser le montage aisé par simple encliquetage sur le poteau de clôture d'un moyen de fixation, dont la hauteur peut être librement sélectionnée par l'utilisateur, de par le mode de fixation retenu. Le fil de tension du grillage ou le fil du grillage lui-même, qu'il soit souple ou rigide, vient se placer à l'intérieur du logement du premier élément. Le deuxième élément solidarise ensuite fermement le fil du grillage en venant bloquer ce fil dans le premier élément et donc sur le poteau de clôture considéré.In other words, the invention makes it possible, by means of said first element, to easily assemble by simple snapping on the fence post of a fixing means, the height of which can be freely selected by the user, by the fastening retained. The tension wire of the mesh or the wire of the mesh itself, whether flexible or rigid, is placed inside the housing of the first element. The second element then firmly secures the wire of the wire mesh by blocking this wire in the first element and thus on the fence post considered.

Selon l'invention, ledit premier élément comprend deux pièces indépendantes, destinées à coopérer l'une avec l'autre, respectivement :

  • une pièce principale, pourvue sur l'une de ses faces du ou des logements destinés à recevoir le fil du grillage ou le fil de tension du grillage, et sur son autre face d'un crochet destiné à coopérer avec le profilé constitutif du poteau ;
  • et une agrafe, également munie d'un crochet destiné à coopérer avec le profilé constitutif du poteau, assurant par sa coopération avec ladite pièce principale, l'encliquetage dudit premier élément sur le profilé constitutif du poteau.
According to the invention, said first element comprises two independent parts, intended to cooperate with each other, respectively:
  • a main part, provided on one of its faces with the housing or for receiving the wire of the mesh or the tension wire of the mesh, and on its other side of a hook for cooperating with the constituent section of the pole;
  • and a clip, also provided with a hook for cooperating with the constituent section of the pole, ensuring by its cooperation with said main part, the snap of said first element on the constituent section of the pole.

Selon une caractéristique de l'invention, le corps constitutif de la pièce principale présente une fente à l'intérieur de laquelle se loge une patte libre de l'agrafe.According to a characteristic of the invention, the constituent body of the main piece has a slot inside which is housed a free tab of the clip.

Selon une autre caractéristique de l'invention, la patte libre de l'agrafe est muni au voisinage de son extrémité d'un ergot, susceptible de se déployer latéralement et destiné à coopérer avec une saillie ménagée à l'intérieur de la fente de la pièce principale, ladite saillie pouvant être constituée par une crémaillère. Cette architecture particulière permet ainsi une adaptation de l'organe à tous types et à toutes dimensions de profilés.According to another characteristic of the invention, the free tab of the clip is provided near its end with a pin, capable of being deployed laterally and intended to cooperate with a projection formed inside the slot of the clip. main piece, said projection may be constituted by a rack. This particular architecture thus allows an adaptation of the body to all types and dimensions of profiles.

La pièce principale et l'agrafe peuvent présenter une forme complémentaire du profilé constitutif du poteau de clôture. En l'espèce, le corps constitutif de la pièce principale vient se plaquer contre la barre supérieure du T, et les crochets respectifs de la pièce principale et de l'agrafe viennent enserrer les extrémités libres de la barre supérieure du T. Ces crochets sont par exemple constitués par le rebord recourbé, notamment en forme de U, respectivement de la pièce principale et de l'agrafe.The main piece and the staple may have a shape complementary to the constituent section of the fence post. In this case, the constituent body of the main piece is pressed against the upper bar of the T, and the respective hooks of the main part and the clip come to grip the free ends of the upper bar T. These hooks are for example constituted by the curved flange, in particular U-shaped, respectively of the main part and the staple.

Le deuxième élément formant couvercle est avantageusement muni de un ou de plusieurs picots, destinés à permettre sa fixation aisée par encliquetage dans des orifices, traversants ou borgnes, ménagés à cet effet au sein du corps constitutif de ladite pièce principale.The second cover member is advantageously provided with one or more pins, intended to allow its easy attachment by snapping into holes, through or blind, provided for this purpose within the body of said main part.

En outre, afin de permettre une adaptation de l'organe conforme à l'invention à plusieurs dimensions de grillages, le deuxième élément formant couvercle peut présenter deux positions de fixation sur le premier élément, définies par l'emplacement desdits picots, les deux positions se dérivant l'une de l'autre par simple rotation dudit couvercle de 180° sur lui-même.In addition, in order to allow an adaptation of the member according to the invention to several mesh sizes, the second cover member may have two fixing positions on the first element, defined by the location of said pins, the two positions. drifting from each other by simply rotating said lid 180 ° on itself.

Conformément à un deuxième aspect de l'invention, une clôture, comprenant des profilés à section transversale en forme de T et un grillage est caractérisée en ce que l'un au moins des fils constitutifs dudit grillage ou participant à sa mise en place est fixé sur les profilés à l'aide d'un ou plusieurs organes de fixation du type de ceux décrits précédemment.According to a second aspect of the invention, a fence comprising T-shaped cross-section profiles and a grid is characterized in that at least one of the constituent wires of said grid or participating in its installation is fixed. on the profiles using one or more fasteners of the type of those described above.

Traditionnellement, la mise en place d'une clôture constituée d'un grillage de type souple (non représentée en détail) impose la tension d'un fil dit « de tension » (1) entre des piquets ou poteaux de clôture (2), érigés à intervalles plus ou moins réguliers ou périodiques. Ce ou ces fils de tension sont fixés sur ces poteaux (2), à raison d'au moins deux fils de tension dans le même plan vertical, afin de conférer une certaine résistance mécanique à la clôture outre une certaine tenue.Traditionally, the establishment of a fence consisting of a flexible type of mesh (not shown in detail) imposes the tension of a thread called "tension" (1) between posts or fence posts (2), erected at more or less regular or periodic intervals. This or these tension son are fixed on these poles (2), at least two son tension in the same vertical plane, to give some strength to the fence in addition to some resistance.

En revanche, lorsque la clôture est constituée de panneaux grillagés de type rigide (3), des pièces spécifiques de formes adaptées à la géométrie des dits panneaux et à la géométrie des piquets ou poteaux sont fixées au piquet ou poteau (2), également en plusieurs lieux dans un même plan vertical, pour assurer la liaison mécanique entre les panneaux grillagés de type rigide et les piquets ou poteaux.On the other hand, when the fence consists of rigid type grid panels (3), specific pieces of shapes adapted to the geometry of said panels and to the geometry of the stakes or posts are fixed to the post or post (2), also in several places in the same vertical plane, to ensure the mechanical connection between the rigid type of grid panels and the stakes or poles.

Le piquet (2) est constitué d'un profilé métallique ou en matériau composite à section transversale en forme de T, susceptible d'être obtenu par des moyens de laminage, d'extrusion ou de profilage..., et ce, de manière connue. Ce piquet (2) comporte deux parties planes, perpendiculaires l'une par rapport à l'autre, respectivement la barre supérieure (7) du T, et la base (8), c'est à dire l'élément classiquement vertical du T.The peg (2) consists of a metal section or T-shaped cross-section composite material that can be obtained by means of rolling, extrusion or profiling ..., and this so known. This peg (2) has two flat portions, perpendicular to each other, respectively the upper bar (7) of the T, and the base (8), ie the classically vertical element of the T .

Si la barre supérieure (7) du T est généralement linéaire ou plane, ses deux extrémités ou bords libres (9, 11) sont susceptibles d'être légèrement recourbés en direction de la base (8), tel que par exemple décrit dans le document FR03/09638 du Demandeur.If the upper bar (7) of the T is generally linear or plane, its two ends or free edges (9, 11) may be slightly bent towards the base (8), as for example described in the document FR03 / 09638 of the Applicant.

Un organe standard de fixation (12), conformément à l'invention, est mis en oeuvre pour assurer la pose et la fixation ferme du fil de tension (1) ou du ou des fils (6) du grillage (3) au niveau des poteaux (2).A standard fastening member (12), according to the invention, is used to ensure the laying and the firm fixing of the tension wire (1) or the wire or wires (6) of the grid (3) at the level of the posts (2).

Selon l'invention, cet organe (12) comprend d'une part, un premier élément assurant sa solidarisation sur le piquet (2), et constitué d'une pièce principale (13) et d'une agrafe (14), et d'autre part un second élément jouant le rôle de couvercle (16), destiné à être rapporté, éventuellement de manière réversible, sur ledit premier élément de solidarisation.According to the invention, this member (12) comprises firstly, a first element ensuring its attachment to the post (2), and consisting of a main part (13) and a clip (14), and secondly a second element acting as a cover (16), intended to be reported, possibly reversibly, on said first securing element.

La pièce principale (13), par exemple réalisée en matière plastique ou composite par injection, par exemple réalisée en polyamide et fibre ou billes de verre, se présente sous la forme d'un parallélépipède ou d'une plaquette rigide (voir Figures 4 à 6), muni d'un fond plat (17), destiné à venir se plaquer contre la surface apparente (18) de la barre supérieure (7) du profilé en T. La face (20) opposée au fond plat (17) de la pièce principale (13) comporte une rainure continue (19) formant logement, destinée à recevoir et à loger le ou les fils (1, 6).The main part (13), for example made of plastic or composite material by injection, for example made of polyamide and fiber or glass beads, is in the form of a parallelepiped or a rigid plate (see Figures 4 to 6 ), provided with a flat bottom (17), intended to be pressed against the apparent surface (18) of the upper bar (7) of the T-section. The face (20) opposite to the flat bottom (17) of the main piece (13) comprises a continuous groove (19) forming a housing for receiving and housing the son or son (1, 6).

L'un des bords de la plaquette constitutive de la pièce principale (13) présente une excroissance recourbée en forme de U (21), formant crochet, revenant partiellement recouvrir le bord du fond plat (17). Dans l'exemple décrit, la largeur de cette excroissance (21) correspond sensiblement au décalage induit par le recourbement des extrémités libres (9) recourbées de la barre supérieure (7) du T du piquet (2), ainsi qu'on peut bien l'observer sur la figure 2. L'extrémité libre (9) recourbée vient se loger au fond du U de l'excroissance (21) de la pièce principale (13). L'excroissance en U (21) en forme de crochet constitue de fait un premier point de fixation du premier élément sur le piquet (2).One edge of the wafer constituting the main piece (13) has a curved protrusion U-shaped (21) forming a hook, returning partially cover the edge of the flat bottom (17). In the example described, the width of this protrusion (21) substantially corresponds to the offset induced by the bending of the curved free ends (9) of the upper bar (7) of the T of the stake (2), as well as observe it on the figure 2 . The curved free end (9) is housed at the bottom of the U of the protuberance (21) of the main piece (13). The hook-shaped U-shaped protuberance (21) is in fact a first point of attachment of the first element on the stake (2).

Ladite pièce principale (13) comporte en outre une fente (22), ménagée au niveau de sa face latérale (23) de la plaquette constitutive, opposée à la face latérale adjacente à l'extrémité (21) en forme de U. La fente (22) débouche à l'intérieur d'un volume interne défini au sein de la plaquette, et comportant une crémaillère (24) définissant une série de crans en saillie. La crémaillère (24) est visible et accessible à partir de la face (20) de la pièce principale (13), grâce à une ouverture (26) débouchant dans le volume accessible par la fente (22).Said main piece (13) further comprises a slot (22) formed at its side face (23) of the constituent wafer, opposite to the side face adjacent to the U-shaped end (21). The slot (22) opens into an internal volume defined within the wafer, and having a rack (24) defining a series of projecting notches. The rack (24) is visible and accessible from the face (20) of the main part (13), through an opening (26) opening into the volume accessible through the slot (22).

Cette pièce principale (13) est destinée à coopérer avec une agrafe (14), ci-après décrite plus en détail. Cette agrafe (14) se présente sous la forme d'un crochet et est réalisée en un matériau souple dans le plan perpendiculaire à l'axe vertical du poteau ou piquet, par exemple métallique réalisé en acier à ressort (voir Figure 7), mais cependant rigide dans l'autre plan. L'agrafe (14) comprend ainsi une première patte ou lame allongée (27), se prolongeant par une excroissance recourbée en forme de U (28) revenant partiellement recouvrir le bord de la lame (27), et constituant le crochet précité. L'excroissance recourbée en forme de U (28) présente au voisinage de son extrémité libre deux pattes latérales (29), s'étendant sensiblement perpendiculairement par rapport au plan défini par l'agrafe. En outre, ces pattes latérales (29) définissent par construction une zone anguleuse et pointue (30), dirigée vers le fond du U constitutif de cette excroissance.This main piece (13) is intended to cooperate with a staple (14), hereinafter described in more detail. This clip (14) is in the form of a hook and is made of a flexible material in the plane perpendicular to the vertical axis of the post or peg, for example metal made of spring steel (see Figure 7 ), but still rigid in the other plane. The clip (14) thus comprises a first lug or elongate blade (27), extending by a bent protrusion U-shaped (28) partially returning to cover the edge of the blade (27), and constituting the aforementioned hook. The curved protrusion U-shaped (28) has in the vicinity of its free end two lateral lugs (29), extending substantially perpendicular to the plane defined by the clip. In addition, these lateral lugs (29) define by construction an angular and pointed zone (30), directed towards the bottom of the U constituting this outgrowth.

Dans l'exemple décrit, la largeur de cette excroissance (28) correspond sensiblement au décalage induit par le recourbement des extrémités libres (9) recourbées de la barre supérieure (7) du T du piquet (2), ainsi qu'on peut bien l'observer sur la figure 2. L'extrémité libre (11) recourbée vient se loger au fond du U de l'excroissance (28) de l'agrafe (14). L'excroissance en U (28) en forme de crochet constitue de fait le second point de fixation du premier élément sur le piquet (2).In the example described, the width of this protrusion (28) substantially corresponds to the offset induced by the bending of the curved free ends (9) of the upper bar (7) of the T of the post (2), so that one can well observe it on the figure 2 . The curved free end (11) is housed at the bottom of the U of the protrusion (28) of the clip (14). The hook-shaped U-shaped projection (28) is in fact the second attachment point of the first element on the stake (2).

Ainsi, la coopération de l'agrafe (14) avec la partie principale (13) permet elle de définir deux points de fixation, susceptible de localiser le lieu de positionnement effectif de l'organe de fixation de l'invention en tout point du piquet (2), et non plus à intervalles plus ou moins réguliers, et en tout cas discrets de l'art antérieur.Thus, the cooperation of the staple (14) with the main part (13) allows it to define two attachment points, able to locate the actual locating position of the fastener of the invention at any point of the stake (2), and no longer at more or less regular intervals, and in any case discrete of the prior art.

A cet effet, la lame allongée (27) de l'agrafe (14) présente une largeur et une épaisseur compatibles avec les dimensions de la fente (22) de la pièce principale (13), afin de permettre son introduction au sein de celle-ci.For this purpose, the elongate blade (27) of the staple (14) has a width and a thickness compatible with the dimensions of the slot (22) of the main part (13), in order to allow its insertion within the -this.

En outre, un ergot (31), issu de découpage, se déploie à partir de la lame allongée (27) au voisinage de son extrémité libre, et en direction de l'excroissance en forme de U (28). Ainsi, lorsque la lame allongée (27) est insérée dans la fente (22) de la pièce principale (13), l'ergot (31) vient coopérer avec l'un des crans de la crémaillère (24), induisant le verrouillage de l'agrafe (14) sur la partie principale (13). Par ce verrouillage, l'ergot (31) empêche toute sortie de la lame (27), et donc de l'agrafe (14) hors de la fente (22) et de ce fait toute désolidarisation de l'agrafe (14) de la pièce principale (13). L'ergot (31) se positionnant entre deux crans de la crémaillère (24) assure un encliquetage de l'agrafe (14) sur la pièce principale (13).In addition, a lug (31), derived from cutting, unfolds from the elongated blade (27) in the vicinity of its free end, and towards the U-shaped protrusion (28). Thus, when the elongate blade (27) is inserted into the slot (22) of the main part (13), the lug (31) cooperates with one of the notches of the rack (24), inducing the locking of the staple (14) on the main part (13). By this locking, the lug (31) prevents any exit of the blade (27), and therefore of the clip (14) from the slot (22) and thus any separation of the clip (14) of the room principal (13). The lug (31) positioned between two notches of the rack (24) ensures a snap of the clip (14) on the main part (13).

La crémaillère (24) permet une adaptation de la longueur de l'organe (12) à plusieurs dimensions de la barre supérieure (7) du piquet (2).The rack (24) allows an adaptation of the length of the member (12) to several dimensions of the upper bar (7) of the peg (2).

Lorsque l'agrafe (14) est ainsi solidarisée à la pièce principale (13), les deux excroissances en U (21, 28), respectivement de la pièce principale (13) et de l'agrafe (14), viennent ainsi enserrer chacune des extrémités libres (9, 11) des deux ailes de la barre supérieure (7) du T du piquet (2).When the staple (14) is thus secured to the main piece (13), the two U-shaped protrusions (21, 28), respectively of the main piece (13) and the staple (14), thus enclose each free ends (9, 11) of the two wings of the upper bar (7) of the T of the peg (2).

Par ailleurs, les principes physiques mis en oeuvre, en l'espèce action - réaction, induisent la tentative de retrait de l'agrafe (14) hors de la fente (22), et donc corollairement le recul de l'excroissance en forme de U (28) selon la direction de la barre supérieure (7) du T, mais selon un sens s'éloignant de la base (8). Partant, les zones anguleuses et pointues (30) ont tendance à pénétrer dans l'aile recourbée (11) de la barre supérieure (7) du T, favorisant ainsi l'ancrage de ce point de fixation. Cet ancrage est en outre optimisé, lorsque le profilé métallique constitutif du piquet (2) est revêtue d'une ou de plusieurs couches de peinture.Moreover, the physical principles used, in this case action-reaction, induce the attempt to withdraw the clip (14) out of the slot (22), and therefore corollary the retreat of the outgrowth in the form of U (28) in the direction of the upper bar (7) of the T, but in a direction away from the base (8). As a result, the angular and pointed zones (30) tend to penetrate into the curved wing (11) of the upper bar (7) of the T, thus favoring the anchoring of this point of attachment. This anchoring is further optimized, when the metal section constituting the post (2) is coated with one or more layers of paint.

En outre, le caractère relativement flexible de l'agrafe (14) permet l'adaptation de l'organe de fixation de l'invention à tout type de profilé en T, et notamment à tout type d'inclinaison des ailes recourbées de la barre supérieure (7) dudit T.In addition, the relatively flexible nature of the clip (14) allows the adaptation of the fastener of the invention to any type of T-profile, including any type of inclination of curved flanges of the bar upper (7) of said T.

Le second élément entrant dans la constitution de l'organe de fixation de l'invention est constitué par un couvercle (16). Celui-ci possède des dimensions complémentaires de celles de la pièce principale (13) (voir Figure 8). Le couvercle (16) ferme le logement (19), lorsque le fil (1, 4 et 6) y est inséré. Le couvercle (16) est muni d'une pluralité de picots (32) faisant saillie en direction de la pièce principale (13). Les picots (32) sont destinés à venir s'insérer dans des orifices borgnes (33), ménagés à cet effet au sein de la face (20), permettant ainsi un encliquetage par pivotement de 180° d'angle du couvercle (16) sur la pièce principale (13).The second element used in the constitution of the fastener of the invention is constituted by a cover (16). It has dimensions complementary to those of the main piece (13) (see Figure 8 ). The lid (16) closes the housing (19) when the wire (1, 4 and 6) is inserted therein. The lid (16) is provided with a plurality of pins (32) projecting towards the main piece (13). The pins (32) are intended to be inserted into blind holes (33), formed for this purpose within the face (20), thus allowing pivoting 180 ° angle of the cover (16). on the main room (13).

Le positionnement de ces orifices (33) au sein de la face (20) de la pièce principale (13) est choisi de façon à permettre une certaine latitude de coopération avec le couvercle (16). En effet, lors de la mise en place du grillage rigide, un fil vertical (4) le constituant est susceptible de gêner le positionnement et le maintien du couvercle (16). Un pivotement de 180° de ce couvercle (16) sur lui-même permet de décaler le lieu de coopération de celui-ci avec la partie principale (13), et partant de ne plus être gêné par ce fil vertical. En effet, ainsi qu'on peut bien l'observer sur les figures 1 et 5, la face (20) de ladite partie principale (13) est munie de deux jeux de quatre orifices (33), décalés l'un par rapport à l'autre de la valeur d'un diamètre environ desdits orifices.The positioning of these orifices (33) within the face (20) of the main part (13) is chosen to allow a certain latitude of cooperation with the cover (16). Indeed, when setting up the rigid mesh, a vertical wire (4) the constituent is likely to hinder the positioning and maintenance of the lid (16). A 180 ° pivoting of this cover (16) on itself allows to shift the place of cooperation thereof with the main part (13), and hence not to be hindered by this vertical wire. Indeed, as we can well observe it on figures 1 and 5 , the face (20) of said main portion (13) is provided with two sets of four orifices (33), offset with respect to each other by the value of about one diameter of said orifices.

On aura bien compris la grande facilité de mise en place de l'organe de fixation de l'invention. Une simple insertion de l'agrafe (14) au sein de la fente latérale (22) de la partie principale (13), suivie d'un serrage manuel, permet de localiser à la hauteur voulue le premier élément de l'organe de fixation.It will be understood the great ease of implementation of the fastener of the invention. A simple insertion of the staple (14) within the lateral slot (22) of the main part (13), followed by a manual tightening, makes it possible to locate at the desired height the first element of the fastener .

Bien évidemment, l'utilisateur positionne ledit premier élément en fonction des contraintes mécaniques ou de localisation des fils, respectivement de tension ou constitutifs du grillage souple ou panneau rigide qu'il est amené à rencontrer.Of course, the user positions said first element as a function of the mechanical stresses or localization of the son or tension or constituent of the flexible mesh or rigid panel that he is brought to meet.

Dans le cas de grillage souple, une fois ce premier élément positionné, il ne lui reste plus qu'à introduire le fil de tension, ou le fil du grillage retenu dans le logement (19) de la partie principale (13) dudit premier élément, puis à obturer celui-ci en rapportant le couvercle (13) à ce niveau.In the case of flexible mesh, once this first element positioned, it only remains for him to introduce the tensioning wire, or the wire of the mesh retained in the housing (19) of the main part (13) of said first element , then to close it by bringing the cover (13) to this level.

Dans le cas de panneau grillagé de type rigide, une fois ce premier élément positionné, il ne lui reste plus qu'à mettre en place une plaque support, non détaillée ici, dudit panneau rigide, dans le logement (19) de la partie principale (13) dudit premier élément, puis à obturer celui-ci en rapportant le couvercle (13) à ce niveau.In the case of rigid type grid panel, once this first element is positioned, it only remains for him to put in place a support plate, not detailed here, of said rigid panel, in the housing (19) of the main part. (13) of said first element, then to close it by bringing the cover (13) to this level.

La présente invention n'est pas limitée aux modes de réalisation décrits et illustrés. De nombreuses modifications peuvent être réalisées, sans pour autant sortir du cadre défini par la portée du jeu de revendications.The present invention is not limited to the embodiments described and illustrated. Many modifications can be made, without departing from the scope defined by the scope of the set of claims.
