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 la domaine des dispositifs de palissage ou de la clôture, à partir de piquets enfoncés dans le sol qui supportent un ou plusieurs fils, selon le préambule de la revendication 1.The invention relates to the field of trellising devices or fencing, from stakes driven into the ground which support one or more wires, according to the preamble of claim 1.

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 des 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 posts because of 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 surcroit, désirable que les piquets répondent aux cinq exigences suivantes:It is moreover desirable that the stakes meet the following five requirements:

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, y avoir de 4 à 7 kilomètres de fils à l'hectare.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 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.Secondly, the stake must not have any sharp edges at the points of contact with the wire, under penalty of causing premature wear of the latter and ultimately breaking.

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'aggression 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'empêchant 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, not preventing the exit of the stretched 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 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 weakened mechanical resistance of the makes 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.

On connait par le document US-A-1.826.182 un dispositif de palissage au moyen de fils (W) de piquets 5 et d'attaches 8 permettant de fixer les fils sur les piquets, le piquet 5 étant un profil en T muni de perforations 6, 7 dans lesquelles on vient fixer l'attache 8. Mais ce dispositif oblige à retirer les attaches 8 de leurs perforations lorsqu'on veut relever les fils (W). D'autre part l'attache étant simplement clipée dans les perforations, le risque de dégagement de cette dernière n'est pas exclu.Document US-A-1.826.182 discloses a trellising device by means of wires (W) of stakes 5 and fasteners 8 making it possible to fix the wires on the stakes, the stake 5 being a T-profile provided with perforations 6, 7 in which the clip 8 is fixed. However, this device requires the clips 8 to be removed from their perforations when the wires (W) are to be raised. On the other hand the clip is simply clipped into the perforations, the risk of release of the latter is not excluded.

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 piquets et d'attaches permettant de fixer les fils sur les piquets, chaque piquet comportant au moins deux perforations pour la fixation d'une attache, dispositif dans lequel:

  • - le piquet est un profil creux, fermé ou non, portant des perforations, les piquets étant disposés en service de telle façon qu'un plan tangent à la section du piquet et passant par les perforations ne soit ni parallèle ni perpendiculaire au plan de palissage; le dit piquet a en service un plan de sy- mètrie parallèle au plan de palissage, les perforations étant disposées dans l'espace défini par l'un ou l'autre des plans tangentiels verticaux parallèles au plan de symétrie et contenant le piquet d'une part, et le dit plan de symétrie d'autre part;
  • - l'attache en service 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 coté de ladite attache, et à cette partie de support se raccorde une partie formant verrou pour le fil de palissage, relevé obliquement en direction du plan médian du piquet parallèle au plan tangentiel précité et dont l'extrémité libre se trouve entre lesdits plans médian ettangentiel.
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, each stake having at least two perforations for fixing a fastener, device in which:
  • - the stake is a hollow profile, closed or not, carrying perforations, the posts being arranged in service so that a plane tangent to the section of the stake and passing through the perforations is neither parallel nor perpendicular to the trellising plane ; the said stake has in service a plane of symmetry parallel to the trellising plane, the perforations being arranged in the space defined by one or the other of the vertical tangential planes parallel to the plane of symmetry and containing the stake on the one hand, and the said plane of symmetry on the other hand;
  • - the fastener in service 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 trellising wire, the length of this part of support being such that when the fastener is fixed to the stake, the end of said part of support opposite the loop-shaped part is outside a vertical plane tangential to 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 above tangential plane and the free end of which lies between said median and tangential planes.

Le piquet peut être de section circulaire, ellipsoïdale 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 comportent deux lignes de perforations 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 have two lines of vertical perforations 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 material savings.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'un exemple non limitatif de réalisation. Cette description se réfère aux dessins annexés, dans lesquels:

  • - la fig. 1 montre schématiquement que lorsqu le palissage est implanté dans un sol convexe, la tension du fil dans les directions T, et T2 produit une force de soulèvement S qui tend à faire sortir le fil 1 de ses attaches sur le piquet 2;
  • - les figures 2 à 7 montrent diverses sortes de systèmes de palissage actuellement connus;
  • - la fig. 8 est une vue de face d'une portion d'un piquet conforme à l'invention en regardant en direction des lignes de perforations;
  • - la fig. 9 est une vue en coupe horizontale selon la ligne VIII-VIII de la figure 8;
  • - la fig. 10 est une vue en plan d'une attache conforme à l'invention;

  • - la fig. 12 est une vue identique à celle de la figure 8, deux attaches selon la figure 10 étant mises en place pour le passage de deux fils de part et d'autre du piquet;
  • - la fig. 13 est une vue en coupe horizontale selon la ligne XII-XII de la figure 12;
  • - la fig. 14 est une vue en perspective d'un piquet selon les figures 12 et 13.
Other characteristics and advantages of the invention will emerge from the description which follows of a nonlimiting exemplary embodiment. This description refers to the attached drawings, in which:
  • - fig. 1 schematically shows that when the trellising is implanted in a convex soil, the tension of the wire in the directions T, and T 2 produces a lifting force S which tends to cause the wire 1 to come out of its attachments on the stake 2;
  • - Figures 2 to 7 show various kinds of trellising systems currently known;
  • - fig. 8 is a front view of a portion of a stake according to the invention looking towards the lines of perforations;
  • - fig. 9 is a horizontal sectional view along the line VIII-VIII of FIG. 8;
  • - fig. 10 is a plan view of a fastener according to the invention;
  • - fig. 11 is a view identiqùe to that of FIG. 8, the fastener of FIG. 10 being placed on the stake;
  • - fig. 12 is a view identical to that of FIG. 8, two fasteners according to FIG. 10 being put in place for the passage of two wires on either side of the stake;
  • - fig. 13 is a view in horizontal section on the line XII-XII in FIG. 12;
  • - fig. 14 is a perspective view of a stake according to FIGS. 12 and 13.

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-dessus 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 above 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, on introduit 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 hole 8, immediately below, through 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'un pince, l'éx- trémité 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 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'extrémité 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 relevé 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 Figures 11, 12, 13 and 14, the end 15 of the part of the fastener 9 forming a support is at the end of a vertical plane tangential to the edge 5, 7 of the stake, said plane being parallel to the trellising plane. The bolt-forming part is raised obliquely in the direction of the median vertical 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 disengage from the fastener 9 under the effect of forces directed upwards, while 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 the end posts, one can build such posts by combining two, three or four stakes.

Claims (5)

1. A fencing device by means of wires, fencing posts and fasteners allowing the wires to be fixed onto the fencing posts, each post (3) comprising at least two holes (8) for fixing a fastener (9) therein, characterized in that:
a) the post (3) is a hollow shaped piece, its profile being either closed or not, provided with holes (8) the posts being arranged when in service so that a plane tangent to the post cross-section and passing through the holes will be neither parallel nor perpendicular to the fencing plane; said post when in service has a plane of symmetry (18) parallel to the fencing plane, the holes (8) being located within the space defined by either of the vertical tangent planes parallel to the plane of symmetry (18) and containing the post on the one hand and the said plane of symmetry (18) on the other hand.
b) the fastener (9) when in service comprises a first loop-shaped portion (10-14) intended for being fixed through two holes (8) of the post (3), a second horizontal portion (14, 15) forming a support for a fencing wire (17), the length of said second portion (14,15) being such that when the fastener (9) is fixed to the post (3), the end (15) of said support portion opposed to the loop-shaped portion finds itself on the exterior of a vertical plane tangent to the edge of the post (3) and parallel to the fencing plane along the side of said fastener (9), and a third portion (15, 16) forming a locking means for the fencing wire (17) and slanting upwards towards the median plane (18) of the post (3) parallel to said above mentioned tangent plane, the free end (16) of said locking portion being comprised between said median plane (18) and said tangent plane.
2. A fencing post for a fencing device according to Claim 1, characterized in that it is formed of a hollow shaped piece (3) with an open profile, comprising at least two holes (8) located opposite to the profile opening (4).
3. A fencing post according to Claim 2, characterized in that it comprises two parallel rows of holes (8) located opposite to the profile opening (4).
4. A fencing post according to Claim 2 or 3, characterized in that it is formed of a shaped piece (3) with a square profile, the aperture (4) of which is located along one of the edges of the square, its three other edges (5, 6, 7) being rounded.
5. A fastener for a fencing device according to Claim 1, characterized in that it comprises a first loop-shaped portion (10-14) intended for being fixed through two holes (8) of a post (3), a second horizontal portion (14, 15) forming a support for a fencing wire (17), the length of said second portion (14, 15) being such that when the fastener (9) is fixed to the post (3), the end (15) of said supporting portion opposite to the loop-shaped portion (10-14) finds itself on the exterior of a vertical plane tangent to the edge of the post (3) and parallel to the fencing plane along the side of said fastener, and a third portion (15, 16) forming a locking means for the wire (17) and slanting upwards towards the median plane (18) of the post (3) parallel to said above-mentioned tangent plane, the free end (16) of said locking portion being comprised between said median plane and said tangent plane when the fastener is in its place on the fencing post.
