Abstract

A wire fence has a hollow elongated stake for supporting a horizontal wire. The stake has vertical rows of perforations for receiving wire fasteners. The perforations are positioned between two vertical planes tangent to vertical extending edges of the stake, the planes being parallel to the wire. The fastener has a loop for insertion into the perforation, a wire support section extending outwardly through the vertical planes, and a free end at the end of the wire support section, which is bent back toward the loop portion so that the wire is held in place.

Description

L'invention concerne le domaine du palissage ou de la clôture, à partir de piquets enfoncés dans le
sol qui supportent un ou plusieurs fils.The invention relates to the field of trellising or fencing, using stakes driven into the
soil that supports one or more wires.

Pour ces applications, les piquets doivent remplir une double fonction de support des fils et de maintien en tension des fils pour les piquets d'extrémité. De ce fait, ils doivent être aptes à résister à des efforts souvent considérables dans deux directions perpendiculaires soit

  • . parallèlement à la direction de palissage pour les piquets d'extrémité en raison de la tension qu'ils supportent;
  • . perpendiculairement à la direction dés fils pour les piquets intermédiaires (cas d'un vent perpendiculaire aux rangs de vigne ou des animaux se frottant aux clôtures);
For these applications, the stakes must fulfill a double function of supporting the wires and keeping the wires in tension for the end stakes. Therefore, they must be able to withstand often considerable efforts in two perpendicular directions is
  • . parallel to the trellising direction for the end stakes due to the tension they bear;
  • . perpendicular to the direction of the wires for intermediate stakes (case of a wind perpendicular to the rows of vines or animals rubbing against the fences);

Il est, de surcroît, désirable que les piquets répondent aux cinq exigences suivantes:

  • Ils doivent permettre de dérouler le fil le long du palissage avant de le fixer à la hauteur désirée, afin d'assurer une mise en place rapide, ce qui n'est pas le cas si le fil doit, par exemple, être enfilé dans un trou. Cette exigence est particulièrement ressentie dans le cas des vignobles, qui exigent des longueurs considérables de fils. En fonction de l'écartement des rangs, il peut, en effet, y avoir de 4 à 7 kilomètres de fils à l'hectare.
In addition, it is desirable that the stakes meet the following five requirements:
  • They must allow the wire to be unrolled along the trellising before fixing it at the desired height, in order to ensure rapid installation, which is not the case if the wire must, for example, be threaded in a hole. This requirement is particularly felt in the case of vineyards, which require considerable lengths of wire. Depending on the row spacing, there may, in fact, be 4 to 7 kilometers of son per hectare.

En second lieu, le piquet ne doit pas présenter d'arêtes vives aux points de contact avec le fil, sous peine d'entraîner une usure prématurée de celui-ci et à terme, sa rupture.Second, the stake must not have sharp edges at the points of contact with the wire, under penalty of causing premature wear of it and ultimately, its rupture.

En troisième lieu, le fil doit pouvoir être facilement mis en place à la hauteur voulue lorsqu'il est détendu, mais une fois mis en tension, il ne doit pas pouvoir sortir de son support et se décrocher, ce qui est souvent le cas dans les cuvettes, le fil étant soumis à une force dirigée vers le haut (figure 1).Thirdly, the wire must be able to be easily set up at the desired height when it is relaxed, but once tensioned, it must not be able to come out of its support and unhook, which is often the case in the bowls, the wire being subjected to a force directed upwards (Figure 1).

En quatrième lieu, dans le cas de vignes, les fils de relevage doivent pouvoir être détendus et sortis de leurs attaches pour être repositionnés en hauteur au fur et à mesure de la montée de la végétation.Fourthly, in the case of vines, the lifting wires must be able to be relaxed and removed from their fasteners to be repositioned in height as the vegetation rises.

Enfin, s'agissant de piquets métalliques, ceux-ci doivent résister à l'agression des produits phytosanitaires répandus sur les vignes ou dans les champs. Il est donc nécessaire d'utiliser des métaux traités, relativement coûteux. Pour éviter un prix prohibitif des piquets, il est donc nécessaire d'utiliser des profils qui procurent une résistance la plus élevée possible pour une section donnée.Finally, in the case of metal stakes, these must resist the aggression of phytosanitary products spread on the vines or in the fields. It is therefore necessary to use treated metals, which are relatively expensive. To avoid a prohibitive price of the stakes, it is therefore necessary to use profiles which provide the highest possible resistance for a given section.

Aucun des systèmes de palissage actuellement connus ne répond simultanément à toutes ces exigences.None of the currently known trellising systems simultaneously meet all these requirements.

Ainsi:

  • . les cornières à trous (figure 2) ne permettent pas de dérouler le fil, présentent aux bords de leurs trous des arêtes saillantes et ne permettent pas l'utilisation de fils de relevage pour la vigne;
  • . les cornières à encoches (figure 3) ont des arêtes vives, n'empêchent pas la sortie du fil tendu lorsque le terrain est concave, et ont une résistance mécanique affaiblie du fait des entailles;
  • . les cornières à barrettes rapportées (figure 4) présentent des arêtes vives, ne permettent pas une manipulation aisée des fils de relevage et exigent un dispositif supplémentaire de fixation des barrettes qui renchérit le coût du système;
  • . les profilés à encoches, tels que ceux représentés aux figures 5 et 6, ont des arêtes vives, n'éliminent pas totalement tout risque de sortie du fil tendu hors des encoches en cas de profil concave du terrain et ont une résistance mécanique affaiblie du fait des encoches;
  • . les profilés perforés avec attaches, tels que ceux représentés sur la figure 7, ne sont pas non plus satisfaisants. En effet, les perforations sont disposées sur les arêtes perpendiculaires aux fils et donc affaiblissent le piquet et leurs bords vifs provoquent l'usure des fils. De surcroît, l'attache a ne permet pas la sortie du fil pour les opérations de relevage, tandis que l'attache b n'évite pas le risque de voir le fil sortir de l'attache lorsque le terrain est vallonné.
So:
  • . the angle iron with holes (FIG. 2) do not allow the wire to be unwound, have protruding edges at the edges of their holes and do not allow the use of lifting wires for the vine;
  • . the notched angles (Figure 3) have sharp edges, do not prevent the exit of the tensioned wire when the ground is concave, and have a weakened mechanical resistance due to the notches;
  • . the angle bars with added bars (Figure 4) have sharp edges, do not allow not easy handling of the lifting wires and require an additional device for fixing the bars which increases the cost of the system;
  • . the notched profiles, such as those shown in FIGS. 5 and 6, have sharp edges, do not completely eliminate any risk of the wire stretched out of the notches in the event of a concave profile of the ground and have a mechanical resistance weakened by the fact notches;
  • . the perforated profiles with fasteners, such as those shown in Figure 7, are also not satisfactory. In fact, the perforations are arranged on the edges perpendicular to the wires and therefore weaken the stake and their sharp edges cause the wires to wear out. In addition, the fastener a does not allow the exit of the wire for lifting operations, while the fastener b does not avoid the risk of seeing the wire leave the fastener when the terrain is hilly.

Le système de palissage conforme à l'invention procure un ensemble de piquets et d'attaches qui répond simultanément aux cinq exigences ci-dessus.The trellising system according to the invention provides a set of stakes and fasteners which simultaneously meets the above five requirements.

L'invention concerne, à cet effet, un dispositif de palissage au moyen de fils, de piquetset d'attaches permettant de fixer les fils sur les piquets, dans lequel:

  • . le piquet est un profil creux, fermé ou non, comportant au moins deux perforations pour la fixation d'une attache, lesdites perforations étant disposées entre les deux plans verticaux tangentiels contenant le piquet parallèles au plan du palissage;
  • . l'attache comporte une partie en forme de boucle destinée à sa fixation dans deux perforations du piquet, à cette partie en forme de boucle se raccorde une partie horizontale de support pour un fil de palissage, la longueur de cette partie de support étant telle que lorsque l'attache est fixée au piquet, l'extrémité de ladite partie de support opposée à la partie en forme de boucle se trouve à l'extérieur d'un plan vertical tangentiel au bord du piquet et parallèle au plan de palissage du côté de ladite attache, et à cette partie de support se raccorde une partie formant verrou pour le fil de palissage, relevée obliquement en direction du plan médian du piquet parallèle au plan tangentiel précité et dont l'extrémité libre se trouve entre lesdits plans médian et tangentiel.
To this end, the invention relates to a trellising device by means of wires, stakes and fasteners making it possible to fix the wires on the stakes, in which:
  • . the stake is a hollow profile, closed or not, comprising at least two perforations for fixing a fastener, said perforations being arranged between the two tangential vertical planes containing the stake parallel to the plane of trellising;
  • . the fastener comprises a part in the form of a loop intended for its fixing in two perforations of the stake, to this part in the form of a loop is connected a horizontal part of support for a wire trellising, the length of this support part being such that when the fastener is fixed to the stake, the end of said support part opposite the loop-shaped part is outside a tangential vertical plane at the edge of the stake and parallel to the trellising plane on the side of said fastener, and to this support part is connected a part forming a lock for the trellising wire, raised obliquely in the direction of the median plane of the stake parallel to the aforementioned tangential plane and of which the free end is between said median and tangential planes.

Le piquet peut être de section circulaire, ellipsoidale ou de forme polygonale.The stake can be circular, ellipsoidal or polygonal in shape.

Lorsque le piquet est à profil ouvert, les perforations ou lignes de perforations sont disposées sensiblement dans la partie du profil opposée à son ouverture.When the stake is with an open profile, the perforations or lines of perforations are arranged substantially in the part of the profile opposite its opening.

Selon un mode préféré de réalisation, un piquet comporte deux lignes de perforations parallèles disposées au voisinage l'une de l'autre, de part et d'autre d'un plan vertical médian du piquet parallèle au plan de palissage.According to a preferred embodiment, a stake has two lines of parallel perforations arranged in the vicinity of one another, on either side of a vertical median plane of the stake parallel to the trellising plane.

Selon un autre mode de réalisation préféré, le piquet est un profil creux de section carrée, ouvert à l'emplacement d'une de ses arêtes, dont les trois autres arêtes sont arrondies et comporte deux lignes de perforation verticales disposées de part et d'autre de l'arête opposée à l'ouverture du profil.According to another preferred embodiment, the stake is a hollow profile of square section, open at the location of one of its edges, the other three edges of which are rounded and has two vertical perforation lines arranged on either side. other of the edge opposite the opening of the profile.

Un tel profil autorise une fabrication en continu; la disposition des perforations assure une valeur optimale du moment d'inertie, ce qui permet d'utiliser des profils plus légers pour une résistance comparable à celle des profils habituels. L'utilisation de profils ouverts procure, en outre, une.économie de matière.Such a profile allows continuous manufacturing; the arrangement of the perforations ensures an optimal value of the moment of inertia, which makes it possible to use lighter profiles for a resistance comparable to that of the usual profiles. The use of open profiles also provides economy. matter.

L'invention concerne encore des pièces d'assemblage pour la réalisation de poteaux d'extrémité à partir de deux piquets ci-dessus et/ou pour l'adaptation de jambes de force sur un desdits piquets.The invention also relates to assembly parts for making end posts from two stakes above and / or for adapting struts on one of said stakes.

L'invention concerne également un crochet spécialement destiné à coopérer avec le piquet pour l'accrochage des chaînettes d'extrémité des fils releveurs et pour l'ancrage des fils d'amarrage et des fils tendeurs.The invention also relates to a hook specially intended to cooperate with the stake for hooking the end chains of the lifting wires and for anchoring the mooring wires and the tensioning wires.

La portion de piquet représentée aux figures 8 et 9 est constituée par un profil creux ouvert 3, de forme sensiblement carrée.The stake portion shown in Figures 8 and 9 is constituted by an open hollow profile 3, of substantially square shape.

L'ouverture 4 est située à l'emplacement de l'une des arêtes du carré.The opening 4 is located at the location of one of the edges of the square.

Les trois autres arêtes 5, 6 et 7 sont arrondies.The other three edges 5, 6 and 7 are rounded.

De part et d'autre de l'arête 6 opposée à l'ouverture 4 sont disposées deux lignes de perforations 8, qui s'étendent verticalement sur toute la hauteur du piquet 3.On either side of the edge 6 opposite the opening 4 are arranged two lines of perforations 8, which extend vertically over the entire height of the stake 3.

L'attache 9, destinée à coopérer avec le piquet 3, est représentée sur la figure 10. Elle est constituée de manière avantageuse en fil d'acier à ressort replié de manière à comporter trois parties fonctionnelles raccordées entre elles, à savoir:

  • Une première partie de fixation en forme de boucle s'étendant du point 10 au point 14 sur la figure 10.
The fastener 9, intended to cooperate with the stake 3, is shown in FIG. 10. It is advantageously made of folded spring steel wire so as to comprise three functional parts connected together, namely:
  • A first loop-shaped fixing part extending from point 10 to point 14 in FIG. 10.

Une partie horizontale de support de fil se raccorde à la partie en forme de boucle. Elle s'étend de 14 à 15 sur la figure 10.A horizontal wire support part connects to the loop-shaped part. It extends from 14 to 15 in Figure 10.

Elle est prolongée par une partie formant verrou s'étendant de 15 à 16, qui s'élève obliquement à partir du point 15 en direction du point supérieur 12 de la partie en forme de boucle.It is extended by a latch part extending from 15 to 16, which rises obliquely from point 15 towards the upper point 12 of the loop-shaped part.

La courbure de la partie en forme de boucle est telle que son extrémité libre 10 s'étend sur une certaine distance, parallèlement à la partie formant support et au-dessous de cette dernière.The curvature of the loop-shaped part is such that its free end 10 extends over a certain distance, parallel to the part forming a support and below the latter.

L'extrémité libre 16 de la partie formant verrou fait saillie au-dessus du point supérieur 12 de la boucle.The free end 16 of the latch portion projects above the upper point 12 of the loop.

Pour mettre l'attache 9 en place sur le piquet 3, ainsi que le montre la figure 11,onintroduit son extrémité 10 dans un trou 8, à la hauteur désirée, cette extrémité 10 se trouve ainsi à l'intérieur du piquet 3. Par un mouvement de rotation, on force cette extrémité 10 à descendre vers le trou 8, immédiatement inférieur, par lequel elle ressort à l'extérieur du piquet. L'attache 9 étant en fil d'acier à ressort, de préférence, reprend sa forme initiale par élasticité.To put the fastener 9 in place on the stake 3, as shown in FIG. 11, its end 10 is introduced into a hole 8, at the desired height, this end 10 is thus inside the stake 3. By a rotational movement, this end 10 is forced to descend towards the hole 8, immediately below, by which it emerges outside the stake. The fastener 9 being made of spring steel wire, preferably, resumes its initial shape by elasticity.

En variante, lorsqu'on utilise pour l'attache une matière non élastique, on donne à la boucle une forme permettant son introduction par rotation dans deux trous successifs du profil, puis on rapproche, par exemple au moyen d'une pince, l'extrémité libre de la boucle du coude 14, ce qui verrouille l'attache.As a variant, when a non-elastic material is used for the fastening, the loop is given a shape allowing it to be introduced by rotation into two successive holes in the profile, and then brought together, for example by means of pliers, free end of the elbow loop 14, which locks the fastener.

Le fil 17, une fois tendu, vient se loger dans le coude 15 de liaison entre la partie du support et la partie formant verrou.The wire 17, once stretched, is housed in the connecting elbow 15 between the part of the support and the part forming a lock.

Comme on le voit plus particulièrement sur les figures 11, 12, 13 et 14, l'extrémité 15 de la partie de l'attache 9 formant support se trouve à l'extérieur d'un plan vertical tangentiel à l'arête 5, 7 du piquet, ledit plan étant parallèle au plan de palissage. La partie formant verrou est relevée obliquement en direction du plan vertical médian 18 du piquet parallèle au plan tangentiel précité et son extrémité libre 16 se trouve comprise entre lesdits plans tangentiel et médian.As seen more particularly in FIGS. 11, 12, 13 and 14, the end 15 of the part of the fastener 9 forming a support is outside of a vertical plane tangential to the edge 5, 7 of the stake, said plane being parallel to the trellising plane. The lock portion is raised obliquely in the direction of the vertical median plane 18 of the stake parallel to the above tangential plane and its free end 16 is between said tangential and median planes.

De la sorte, lorsque le fil 17 est tendu, il ne peut se dégager de l'attache 9 sous l'effet des forces dirigées vers le haut, alors que lorsqu'il est détendu, il peut être facilement sorti de l'attache, par exemple pour les opérations de relevage.In this way, when the wire 17 is stretched, it cannot be released from the fastener 9 under the effect of the forces directed upwards, whereas when it is relaxed, it can be easily released from the fastener, for example for lifting operations.

Comme on le voit sur les figures 12 et 13, la disposition de deux lignes de perforations de part et d'autre de l'arête 6 du piquet 3 autorise la mise en place de fils de part et d'autre du piquet.As seen in Figures 12 and 13, the arrangement of two lines of perforations on either side of the edge 6 of the stake 3 allows the establishment of son on either side of the stake.

Cette disposition des perforations autorise, d'autre part, la combinaison de plusieurs piquets entre eux pour former des poteaux d'extrémité de résistance élevée.This arrangement of the perforations allows, on the other hand, the combination of several stakes between them to form end posts of high strength.

En fonction de la résistance demandée pour les poteaux d'extrémité, on peut constituer de tels poteaux en combinant deux, trois ou quatre piquets.Depending on the resistance required for end posts, one can build such posts by combining two, three or four stakes.

La figure 15 montre un exemple de disposition de quatre piquets assemblés de manière à ce que leurs perforations coïncident et solidarisés par des boulons passant dans lesdites perforations.Figure 15 shows an example of arrangement of four stakes assembled so that their perforations coincide and secured by bolts passing through said perforations.

La figure 16 montre un outil 19, spécialement conçu pour la pose des piquets 3, conforme à l'invention. L'outil comporte un corps méplat 20, d'une épaisseur lui permettant d'être introduit par l'ouverture 4 du piquet 3 et d'une largeur sensiblement égale au diamètre de celui-ci.Figure 16 shows a tool 19, specially designed for the installation of stakes 3, according to the invention. The tool comprises a flat body 20, of a thickness allowing it to be introduced through the opening 4 of the stake 3 and of a width substantially equal to the diameter of the latter.

Sur ce méplat 20 est fixée une tête 21.On this flat 20 is fixed a head 21.

Le méplat 20 sert de guide à l'enfoncement du piquet dont il évite le flambage, tandis que la tête 21 qui reçoit les coups de masse assure une meilleure répartition des forces sur le pourtour du piquet et évite sa détérioration.The flat 20 serves as a guide for the insertion of the stake from which it avoids buckling, while the head 21 which receives the blows of mass ensures a better distribution of the forces around the periphery of the stake and prevents its deterioration.

Les poteaux d'extrémité tels que celui qui est représenté sur la figure 15, sont capables,de supporter des efforts considérables. Cependant ils sont difficiles à mettre en place correctement, car leur résistance à la pénétration dans le sol est élevée.End posts such as that shown in Figure 15, are capable of withstanding considerable efforts. However, they are difficult to install correctly, since their resistance to penetration into the ground is high.

Les figures 17 et 18 représentent un mode avantageux de réalisation d'un poteau simplifié à deux piquets dont les performances sont analogues à celles d'un poteau à quatre piquets et dont la pose est beaucoup plus aisée.Figures 17 and 18 show an advantageous embodiment of a simplified post with two posts whose performance is similar to that of a post with four posts and whose installation is much easier.

A cet effet, on utilise, selon l'invention, au moins une, de préférence plusieurs pièces de moisage 22 pour solidariser entre eux deux piquets 3 opposés par une arête ouverte 4.For this purpose, use is made, according to the invention, of at least one, preferably several mold pieces 22, to join together two stakes 3 opposite by an open edge 4.

La pièce de moisage 22 est un profilé formé à partir d'une plaque pliée et comportant une âme 23, éventuellement nervurée, de part et d'autre de laquelle se raccordent deux parties 24, 25 ayant une forme correspondant à celle du piquet 3, mais de dimensions légèrement différentes, de sorte qu'elles puissent être coulissées à l'extérieur ou à l'intérieur d'un piquet.The mold piece 22 is a profile formed from a folded plate and comprising a core 23, possibly ribbed, on either side of which is connect two parts 24, 25 having a shape corresponding to that of the stake 3, but of slightly different dimensions, so that they can be slid outside or inside a stake.

Les parties 24 et 25 comportent au moins deux perforations 28, taraudées ou non, destinées à coopérer avec les perforations 8 d'un piquet 3, pour la fixation de l'ensemble par des moyens appropriés tels que des vis ou des boulons.The parts 24 and 25 comprise at least two perforations 28, tapped or not, intended to cooperate with the perforations 8 of a stake 3, for fixing the assembly by appropriate means such as screws or bolts.

Dans l'exemple représenté, la forme des parties 24 et 25 de la pièce de moisage 22 est un U, dont les ailes sont repliées sensiblement à angle droit par rapport au fond.In the example shown, the shape of the parts 24 and 25 of the mold piece 22 is a U, the wings of which are folded back substantially at right angles to the bottom.

Deux perforations 28, de préférence taraudées, sont disposées de part et d'autre de l'arête externe 26, 27 desdites parties en U 24 et 25, selon deux plans espacés verticalement l'un de l'autre d'une distance égale au pas des perforations 8 d'un piquet 3.Two perforations 28, preferably tapped, are arranged on either side of the external edge 26, 27 of said U-shaped parts 24 and 25, in two planes spaced vertically from one another by a distance equal to the not perforations 8 of a stake 3.

Les parties en U 24 et 25 sont disposées symétriquement de part et d'autre de l'âme 23 et leur face de raccordement forme avec le plan de ladite âme 23 un angle de 135°.The U-shaped parts 24 and 25 are arranged symmetrically on either side of the core 23 and their connecting face forms with the plane of said core 23 an angle of 135 °.

Comme on le voit sur la figure 18, les deux piquets 3 à assembler sont présentés avec leurs arêtes ouvertes tournées l'une vers l'autre et les parties en U 24 et 25 de la pièce de moisage 22 sont coulissées à l'intérieur de chaque piquet jusqu'au niveau désiré, l'ensemble étant alors fixé par des boulons passant dans les perforations 8 des piquets 3 et 28 des parties en U 24 et 25. De préférence, les perforations 28 sont des trous taraudés, ce qui dispense de l'usage d'écrous.As can be seen in FIG. 18, the two stakes 3 to be assembled are presented with their open edges facing one another and the U-shaped parts 24 and 25 of the mold piece 22 are slid inside each stake to the desired level, the assembly then being fixed by bolts passing through the perforations 8 of the stakes 3 and 28 of the U-shaped parts 24 and 25. Preferably, the perforations 28 are tapped holes, which dispenses with the use of nuts.

L'ensemble ainsi formé constitue une poutre très résistante capable de supporter des efforts de flexion très importants.The assembly thus formed constitutes a very resistant beam capable of withstanding very high bending forces.

Le nombre de pièces de moisage 22 à utiliser dépend de la hauteur du poteau et de l'effort auquel il est soumis. En général, un espacement tous les 50 centimètres est suffisant.The number of mold pieces 22 to use depends on the height of the post and the force to which it is subjected. In general, a spacing every 50 centimeters is sufficient.

De préférence, la pose d'un tel poteau d'extrémité s'effectue selon le mode opératoire suivant qui permet de n'enfoncer qu'un seul piquet à la fois:

  • On fixe sur un piquet 3, aux emplacements souhaités, le nombre de pièces de moisage requis à l'aide de vis ou de boulons. On enfonce ensuite ledit piquet 3 à son emplacement définitif dans le sol à l'aide de l'outil 19. On enfile alors un second piquet 3 sur les parties 24 ou 25 restées libres des pièces de moisage 22, l'ensemble déjà posé faisant fonction de guide pour la pose du second piquet, on enfonce ce dernier de la même manière que le précédent et on le fixe sur les pièces de moisage 22 à l'aide de vis ou de boulons.
Preferably, the installation of such an end post is carried out according to the following operating mode which makes it possible to drive in only one stake at a time:
  • The number of mold pieces required is fixed on a stake 3, at the desired locations, using screws or bolts. Said stake 3 is then driven into its final location in the ground using the tool 19. A second stake 3 is then threaded onto the parts 24 or 25 left free of the mold pieces 22, the assembly already laid forming guide function for the installation of the second stake, the latter is driven in the same way as the previous one and fixed on the mold pieces 22 using screws or bolts.

Pour certaines applications, il peut être souhaitable de doter un piquet 3 d'une ou deux jambes de force. C'est le cas notamment lorsqu'on utilise le piquet 3 pour un palissage en terrain clos dans lequel il n'y a pas d'espace au-delà du piquet de tête pour disposer le ou les ancrages.For certain applications, it may be desirable to provide a stake 3 with one or two struts. This is the case in particular when the post 3 is used for trellising in closed terrain in which there is no space beyond the head post for placing the anchor (s).

Ceci est rendu possible selon l'invention en utilisant les pièces d'assemblage spéciales 29 et 35 représentées aux figures 19 et 21.This is made possible according to the invention by using the special assembly parts 29 and 35 shown in FIGS. 19 and 21.

Pour le montage d'une seule jambe de force, on utilise la pièce 29 représentée à la figure 19. Cette pièce comporte une partie 25', analogue aux parties 24 et 25 de la pièce de moisage 22 et destinée à coopérer avec le piquet 3, à laquelle se raccorde une oreille de fixation 30, munie d'une perforation 32. Dans l'exemple représenté, la partie 25' a la forme d'un U dont les ailes sont repliées à angle droit par rapport au fond, l'oreille 30 formant un angle de 135° avec l'aile à laquelle elle se raccorde. De part et d'autre de l'arête opposée à l'oreille 30, sont disposées deux perforations 31, de préférence taraudées, dans deux plans espacés verticalement d'une distance égale au pas des perforations 8 d'un piquet 3.For the mounting of a single strut, the part 29 shown in FIG. 19 is used. This part comprises a part 25 ′, similar to the parts 24 and 25 of the mold part 22 and intended to cooperate with the stake 3 , to which a fixing lug 30 is connected, provided with a perforation 32. In the example shown, the part 25 ′ has the shape of a U whose wings are folded at right angles by relative to the bottom, the ear 30 forming an angle of 135 ° with the wing to which it is connected. On either side of the edge opposite the ear 30, two perforations 31, preferably tapped, are arranged in two planes spaced vertically by a distance equal to the pitch of the perforations 8 of a stake 3.

Comme le montre la figure 20, on fixe une pièce 29 à l'extrémité supérieure d'un piquet 3 destiné à faire fonction de jambe de force, on fixe une autre pièce 29 dans un second piquet 3 et l'on solidarise les deux par un boulon 33 passant dans les perforations des deux oreilles 29, après avoir donné à la jambe de force l'inclinaison souhaitée.As shown in FIG. 20, a part 29 is fixed to the upper end of a stake 3 intended to act as a strut, another part 29 is fixed in a second stake 3 and the two are secured by a bolt 33 passing through the perforations of the two ears 29, after having given the strut the desired inclination.

De préférence, on rigidifie l'ensemble au moyen d'une entretoise 34 montée sur deux pièces supplémentaires 29 fixées de manière appropriée au piquet et à la jambe de force.Preferably, the assembly is stiffened by means of a spacer 34 mounted on two additional parts 29 fixed in an appropriate manner to the stake and to the strut.

Pour le montage de deux jambes de force en équerre, sur un piquet 3, on utilise des pièces 35, telles que celles représentées sur la figure 21 et des pièces 29.For the mounting of two struts at an angle, on a stake 3, parts 35 are used, such as those shown in FIG. 21 and parts 29.

La pièce 35 comporte une partie 36 de forme correspondant à celle du piquet 3, mais de dimensions légèrement différentes. A cette partie se raccordent deux oreilles de fixation 37 divergeant vers l'extérieur, formant entre elles un angle de même valeur que celui des clôtures, généralement un angle droit.The part 35 comprises a part 36 of shape corresponding to that of the stake 3, but of slightly different dimensions. To this part are connected two fixing ears 37 diverging towards the outside, forming between them an angle of the same value as that of the fences, generally a right angle.

Les oreilles 37 comportent, comme l'oreille 30 de la pièce 29, une perforation 32. La partie 36 est munie de perforations 31, destinées à coopérer avec les perforations 8 d'un piquet.The ears 37 include, like the ear 30 of the part 29, a perforation 32. The part 36 is provided with perforations 31, intended to cooperate with the perforations 8 of a stake.

Dans l'exemple représenté sur la figure 21, la partie 36 de la pièce 35 est un profil carré ouvert dont les deux bords d'ouverture sont prolongés par les oreilles 36 divergeant vers l'extérieur en formant entre elles un angle droit.In the example shown in Figure 21, the part 36 of the part 35 is an open square profile whose two opening edges are extended by the ears 36 diverging outwardly forming between them a right angle.

Les perforations 31, de préférence taraudées, sont disposées de part et d'autre de l'arête opposée à l'ouverture du profilé 36 selon deux plans espacés verticalement d'une distance égale au pas des perforations 8 d'un piquet 3.The perforations 31, preferably tapped, are arranged on either side of the edge opposite the opening of the profile 36 in two planes spaced vertically by a distance equal to the pitch of the perforations 8 of a stake 3.

A l'aide de cette pièce 35, on peut, d'une manière analogue à ce qui a été décrit ci-dessus pour la pièce 29, monter sur un piquet 3 deux jambes de force disposées dans des plans perpendiculaires, ainsi qu'il est montré en plan sur la figure 22.With the aid of this part 35, it is possible, in a manner analogous to what has been described above for part 29, to mount on a stake 3 two struts arranged in perpendicular planes, as it is shown in plan in Figure 22.

Chacune des jambes de force est constituée par un piquet ou une portion de piquet 3 à la tête duquel on a boulonné une pièce d'assemblage 29. Des entretoises peuvent également être montées au moyen d'une pièce 35 supplémentaire et de deux autres pièces 29.Each of the struts consists of a stake or a portion of stake 3 at the head of which a connecting piece 29 has been bolted. Spacers can also be mounted by means of an additional piece 35 and two other pieces 29 .

Ainsi qu'il a été décrit précédemment, le piquet 3 et son agrafe 9 ont été conçus de manière à éviter toute arête vive aux endroits où portent les fils, afin de diminuer l'usure de ces derniers. Dans le même but, l'invention prévoit pour l'attache des différents fils et amarres sur les piquets d'extrémité, un crochet 38 s'adaptant aux perforations 8 du piquet 3.As described above, the stake 3 and its clip 9 have been designed so as to avoid any sharp edge at the places where the wires carry, in order to reduce the wear of the latter. For the same purpose, the invention provides for the attachment of the various threads and moorings on the end stakes, a hook 38 adapting to the perforations 8 of the stake 3.

Ce crochet 38, représenté sur la figure 23, est constitué par un fil de préférence métallique conformé en un S, dont les boucles ont une large ouverture. De préférence, les deux boucles du crochet sont disposées dans deux plans différents.This hook 38, shown in Figure 23, is constituted by a wire preferably metallic shaped like an S, the loops of which have a wide opening. Preferably, the two hook loops are arranged in two different planes.

Par sa forme en S à ouverture large, le crochet 38 permet d'une mise à hauteur très aisée des différents fils venant s'amarrer à un piquet d'extrémité, à savoir les fils tendeurs 39, les fils d'ancrage 40 et les fils de relevage 41 (figure 18).By its S shape with wide opening, the hook 38 allows a very easy height adjustment of the various wires coming to moor at an end stake, namely the tensioning wires 39, the anchoring wires 40 and the lifting wires 41 (Figure 18).

Le crochet 38 est simplement passé dans deux perforations 8 adjacentes du piquet 3, disposées dans le même plan horizontal, tandis que les fils sont amarrés sur sa boucle restée libre.The hook 38 is simply passed through two adjacent perforations 8 of the stake 3, arranged in the same horizontal plane, while the wires are moored on its loop which has remained free.

Le crochet 38 permet également d'utiliser en combinaison avec le piquet 3 selon l'invention, les dispositifs de relevage courants, tels que les chai- nettes 42 (figure 18).The hook 38 also makes it possible to use, in combination with the stake 3 according to the invention, the current lifting devices, such as the chains 42 (FIG. 18).
