Description

DISPOSITIF DE GUIDAGE DE FILS RELEVEURS UTILISES DANS LE DOMAINE DU PALISSAGE EN ARBORICULTURE ET EN VITICULTURE, ET DISPOSITIF POUR SA MISE EN ŒUVRE. La présente invention a pour objet, dans le domaine du palissage en arboriculture et en viticulture, un dispositif de guidage de fils dits releveurs. Lors de la croissance de la végétation, les jeunes pousses s'allongent de manière sensiblement verticale, et le feuillage se développe de sorte qu'au bout d'un certain temps cette végétation a tendance à retomber sous l'effet de son propre poids. Afin de remédier à ce problème il est connu de procéder au palissage de cette végétation, lequel consiste à lier ces tiges à des fils de palissage s'étendant entre des piquets. II est encore connu d'utiliser des fils dits releveurs, disposés de part et d'autre des piquets, à proximité du sommet de ceux-ci, et entre lesquels la végétation est destinée à être contenue. A l'automne, après l'opération de la taille, les fils releveurs sont décrochés des piquets, pour n'être raccrochés qu'au printemps lors de l'opération de palissage et de relevage, qui permet d'augmenter la surface foliaire, pour favoriser la maturation des grains de raisin ou l'administration des produits de traitement de cette végétation. Un tel relevage consiste à faire se rapprocher les fils releveurs de part et d'autre de la végétation et à les maintenir resserrés, notamment à l'aide d'agrafes disposées tels des cavaliers par-dessus ces deux fils. Dans ce but on utilise des dispositifs aptes à permettre le maintien de manière réversible de ces fils dits releveurs, qui consistent en des gorges rétentrices pratiquées de part et d'autre du piquet comme décrit dans les documents DE 20 39 580 et US 2.011.716, soit en des dispositifs rapportés sur le piquet et comportant de telles gorges comme décrit dans le document US 3.411.754. On connaît également des dispositifs, usuellement dénommés écarteurs, conçus aptes à être rendus solidaires d'un piquet et comportant deux branches s'étendant chacune de part et d'autre dudit piquet et présentant au niveau de leur extrémité libre un anneau dans lequel est enfilé le fil. De tels dispositifs sont décrits dans les documents EP 0 876 756 et CH 685 187. Les branches peuvent prendre deux positions extrêmes dans lesquelles les fils sont soit écartés l'un de l'autre, soit resserrés. Le dispositif du document CH 685 187 prévoit une intervention manuelle pour la mise en place, que ce soit dans une position ou dans l'autre, de chacune des branches, avantageusement, le dispositif écarteur décrit dans le document EP 0 876 756 est muni d'un moyen ressort permettant le passage automatique de la position resserrée à la position écartée dès la libération des branches dont les extrémités sont prévues aptes à être maintenues par un moyen d'accrochage. On notera qu'il est également fréquent d'utiliser des fils releveurs de pieds, permettant de maintenir la végétation basse de la vigne, et qui sont équipés de dispositifs écarteurs similaires à ceux précédemment décrits. Ces divers dispositifs sont d'une utilisation fastidieuse, en outre, ils nécessitent une adaptation particulière de la plantation en ce sens qu'il n'est pas possible, sauf à procéder à d'importantes modi ications, de les mettre en œuvre sur des installations existantes. Cet inconvénient est, dans la plupart des cas, lié au fait que les dispositifs existants sont d'une utilisation en rapport à une configuration particulière du pique . Un autre inconvénient des dispositifs existants consiste en ce qu'ils sont, usuellement, rendus solidaires du piquet par fixation à une hauteur déterminée. Ceci permet uniquement un relevage de la végétation à une hauteur déterminée mais ne permet aucunement d'assurer un relevage par palier et en accompagnant la croissance de la végétation. La présente invention a pour but de remédier à ces divers inconvénients en proposant un dispositif de guidage de fils dits releveurs qui présente le grand avantage d'être indépendant du type de piquets utilisés, et qui s'installe sans aucune modification de l'installation existante. Le dispositif de guidage de fils releveurs selon l'invention est du type fait de fil métallique mis en forme par pliage, et il se caractérise essentiellement en ce qu'il comprend d'une part un pliage en forme de boucle; et d'autre part à une extrémité d'un brin s'étendant dudit pliage en forme de boucle, un premier pliage apte à permettre l'accrochage d'un fil releveur, prolongé, en partie extrême, d'un second pliage formant crochet, apte à permettre le crochetage du second fil releveur après rapprochement des deux dits fils releveurs. La boucle est destinée à permettre la solidarisation du dispositif sur un piquet avec possibilité de pivotement sur ce dernier, ou bien à permettre, par une approche latérale, son accrochage sur un fil de palissage, et à autoriser, après accrochage, son libre pivotement sur ledit fil de palissage. Ce dispositif est particulièrement avantageux lorsqu' il est destiné à être accroché sur un fil de palissage, puisqu'il ne nécessite pas de piquet, et qu'il est ainsi possible d'en utiliser autant que voulu entre deux piquets. Selon une caractéristique additionnelle du dispositif selon l'invention, lorsqu'il est destiné à être accroché sur un fil, le pliage en forme de boucle consiste en un enroulement sur plus de 360° avec une zone de chevauchement des spires où celles-ci sont non jointives pour permettre l'engagement du fil de palissage. Selon une autre caractéristique additionnelle du dispositif selon l'invention, le premier pliage apte à permettre l'accrochage d'un fil releveur consiste en une succession de deux plis à angle droit pour former d'une part une section parallèle à l'axe de passage du fil de palissage dans le pliage en forme de boucle, pour permettre l'entortillement du fil releveur, et deux segments radiaux à ladite section et destinés à maintenir entortillé ledit fil. Selon une autre caractéristique additionnelle du dispositif selon l'invention, le second pliage formant crochet, apte à permettre le crochetage du second fil releveur consiste en un pliage pour former un crochet s' inscrivant dans un plan perpendiculaire à l'axe de passage du fil de palissage dans le pliage en forme de boucle. Selon un mode de réalisation particulier du dispositif selon l'invention, le second pliage formant crochet est conformé en forme de flèche présentant deux zones rétentrices et en extrémité une partie triangulaire déviatrice en sorte de permettre le crochetage du fil releveur par le dessus ou par le dessous . Selon un premier mode de réalisation particulier du dispositif selon l'invention, il comporte deux brins rectilignes s'étendant depuis le pliage en forme de boucle en faisant un angle l'un par rapport à l'autre, et dont chacun est muni, à son extrémité, d'un premier et d'un second pliage pour l'accrochage des deux ils releveurs . Selon une variante du premier mode de réalisation du dispositif selon l'invention, les extrémités des brins rectilignes sont pliées de manière symétrique l'une par rapport à l'autre. Selon un second mode de réalisation particulier du dispositif selon l'invention, il comporte deux brins rectilignes s'étendant depuis le pliage en forme de boucle en étant alignés l'un par rapport à l'autre, l'un étant muni à son extrémité d'un premier et d'un second pliage pour l'accrochage et le crochetage de deux fils releveurs, tandis que l'autre est muni à son extrémité d'un moyen, analogue audit pliage en forme de boucle, d'accrochage d'un fil releveur de pieds . Selon une caractéristique additionnelle du second mode de réalisation particulier du dispositif selon l'invention, le brin rectiligne s'étendant entre le pliage en forme de boucle et le premier et le second pliage pour l'accrochage et le crochetage de deux fils releveurs, comporte dans sa région médiane une double boucle destinée à l'accrochage d'un fil releveur intermédiaire. Afin de faciliter la mise en œuvre du dispositif selon l'invention, quel que soit son mode de réalisation, il est avantageusement prévu que les fils releveurs présentent sur leur longueur une certaine élasticité, ce qui est obtenu en disposant, en un ou plusieurs emplacements, des éléments extensibles tels que des ressorts. De tels éléments peuvent être solidarisés à chacune des extrémités des fils, et servir à l'accrochage de ceux-ci aux piquets de tête. Ces éléments peuvent consister en des éléments en forme d'agrafes venant du cintrage d'un fil de métal plié, qui de préférence consiste en un métal inoxydable de qualité ressort, déformable élastiquement et présentant en extrémités des moyens d'accrochage, pour l'un à un fil et pour l'autre à un piquet. Il est aussi possible de prévoir une agrafe solidarisable à un piquet et à laquelle peuvent être accrochées les extrémités des fils releveurs, permettant de maintenir les fils dans deux positions, écartés ou rapprochés, et présentant des facultés d'extension élastique dans le sens longitudinal desdits fils. La présente invention a également pour objet un dispositif pour la mise en œuvre du dispositif de guidage selon l'invention, et plus particulièrement lors de l'opération de relevage. Ce dispositif de mise en œuvre se caractérise essentiellement en ce qu'il comporte deux cylindres d'axes verticaux, de surface cylindrique ajourée, portés par un bâti destiné à être déplacé parallèlement à la végétation, rappelés l'un vers l'autre, aptes à rouler sur les fils releveurs de part et d'autre de ceux-ci en exerçant une pression pour les rapprocher jusqu'à permettre le crochetage, ladite de surface cylindrique ajourée étant à cet effet conçue apte à permettre aux pliages formant crochet de pénétrer à l'intérieur desdits cylindres en vue du crochetage desdits fils. Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente plusieurs modes de réalisation non limitatifs. Dans le dessin annexé : - la figure 1 représente une vue schématique en élévation de face d'un premier mode de réalisation du dispositif selon l'invention. - la figure 2 représente une vue schématique en élévation de profil du même mode de réalisation. - la figure 3 représente une vue schématique de dessus du même mode de réalisation. - la figure 4 représente une vue schématique en élévation de face d'un second mode de réalisation du dispositif selon l'invention. - la figure 5 représente une vue schématique en élévation de profil du même mode de réalisation. - la figure 6 représente une vue schématique de dessus du même mode de réalisation. - les figures 7a, 7b, 7c et 7d représentent des vues schématiques en plan de variantes du dispositif selon l'invention. - la figure 8a représente une vue schématique de profil d'un mode de réalisation particulier du dispositif selon l'invention. - la figure 8b représente une vue schématique en plan de ce mode de réalisation particulier. - la figure 9 représente une vue schématique en plan d'un dispositif pour la mise en œuvre du dispositif selon l'invention. - la figure 10 représente une schématique partielle en élévation du même dispositif. En référence aux figures 1, 2 et 3, on peut voir un premier mode de réalisation 1 du dispositif de guidage de fils dits releveurs selon l'invention. Comme représenté sur la figure 3, le dispositif 1 est destiné à coopérer avec d'une part un fil de palissage 2 porté par un piquet P qu'il traverse, et d'autre part deux fils releveurs 20 et 21 non solidaires du piquet P. Le dispositif 1 se présente sous la forme d'un fil de métal plié, qui de préférence consiste en un métal inoxydable de qualité ressort. Il comporte dans sa région médiane un pliage en forme de boucle 10 comprenant une ouverture centrale 11 destinée au passage du fil de palissage 2. La boucle 10 est conformée pour permettre la mise en place du dispositif 1 sur le fil 2 par une approche latérale alors que celui-ci est tendu, à cet effet elle est constituée d'un enroulement supérieur à 360° pour permettre la création d l'ouverture centrale 1, tandis que dans zone de superposition des spires ces dernières sont non jointives pour permettre l'engagement du fil 2. En pratique le dispositif 1 est approché du fil 2 qui est engagé entre les deux spires de la boucle 10, puis en faisant faire un quart de tour au dispositif 1 on maintient le fil 2 dans l'ouverture centrale 11. De la boucle 10 du dispositif 1 s'étendent deux brins rectilignes 4 et 5 faisant entre eux un certain angle, en l'occurrence de l'ordre de 60°, et dont les extrémités sont conformées pour l'accrochage des fils releveurs 20 et 21. L'extrémité 40 du brin 4 présente ainsi d'une part un pli 41 à angle droit qui génère une section rectiligne 42 parallèle à l'axe de l'ouverture centrale 11 de la boucle 10, et d'autre part un pli 43 à angle droit pour former un segment rectiligne 44 perpendiculaire au plan formé par le brin 4 et la section rectiligne 42. Comme on peut le voir plus précisément sur la figure 3, le fil releveur 20 est destiné à être entortillé sur la section rectiligne 42, le segment rectiligne 44 ainsi que le brin 4 au niveau du pli 41 contribuant à maintenir le fil 20 entortillé. Le segment 44 comporte en extrémité un pliage 45 en forme de flèche, s'étendant dans un plan perpendiculaire à l'axe de l'ouverture 11 de la boucle 10. Ce pliage 45 en forme de flèche présente du côté du segment 44 deux zones rétentrices 46 et 47, positionnées respectivement au-dessus et en dessous du segment 44, et en extrémité une partie triangulaire 48 déviatrice. De la même manière, le brin 5 comporte à son extrémité 50, un pli 51 à angle droit, une section rectiligne 52, un pli 53 à angle droit, un segment rectiligne 54, en extrémité un pliage 55 en forme de flèche présentant deux zones rétentrices 56 et 57, et une partie triangulaire 58 déviatrice. Le brin 5 est toutefois, symétrique au brin 4 en ce sens que le pli 41 est réalisé dans la direction inverse du pli 51. La section rectiligne 52 est bien entendu destinée à l'entortillement du fil releveur 21, tandis que le segment rectiligne 54 ainsi que le brin 5 au niveau du pli 51 contribuent à maintenir le fil 21 entortillé. On notera que l'entortillement des fils 20 et 21 sur les sections rectilignes, respectivement 42 et 52, du fait du serrage des sections par les fils 20 et 21, contribue à maintenir le dispositif 1 dans une position fixe par rapport à ces fils 20 et 21, et de préférence, selon la manière dont il est installé, dans un plan perpendiculaire à ces fils 20 et 21. Dans la configuration représentée sur les figures 1, 2 et 3, les brins 4 et 5 sont écartés, c'est-à-dire qu'ils maintiennent écartés les fils releveurs 20 et 21 pour permettre la croissance de la végétation. Lorsqu'il est nécessaire de resserrer la végétation, on procède au relevage des fils releveurs 20 et 21, ce qui, comme cela est représenté en trait discontinu sur la figure 1, est réalisé aisément par leur rapprochement en saisissant par exemple les sections rectilignes 42 et 52 du dispositif 1, et en crochetant d'une part le fil 20 avec le pliage 55 en forme de flèche, le fil 20 se calant dans l'une des zones rétentrices 56 et 57 selon qu' il passe au-dessus ou en dessous de la partie triangulaire 58 déviatrice, et d' autre part le fil releveur 21 avec le pliage 45 en forme de flèche, le fil 21 se calant dans l'une des zones rétentrices 46 et 47 selon qu'il passe au-dessus ou en dessous de la partie triangulaire 48 déviatrice. Le relâchement des fils releveurs 20 et 21 est réalisé en opérant la manœuvre inverse, c'est-à-dire en les désengageant des pliages 45 et 55 en forme de flèche, et par un effet ressort les deux brins 4 et 5 s'ouvrent. On notera qu' il peut être nécessaire d' adjoindre au dispositif 1 des moyens permettant de limiter le déplacement des fils releveurs 20 et 21, afin d'éviter que les dispositifs 1 qui équipent _ une route de vigne ne bascule d'un côté avec la végétation. De tels moyens peuvent par exemple consister en des chaînettes ou analogues, de longueur choisie et reliant chacun des fils 20 et 21 à un piquet P ou à un fil de palissage fixe tel que le fil 2 ou un autre analogue. Le dispositif 1 selon l'invention est indépendant du type de piquet utilisé pour supporter le fil de palissage 2, et il est adaptable sur les fils 2, 20 et 21, alors que ceux-ci sont déjà en place. Ce dispositif peut donc aisément être utilisé sur les installations existantes sans réaménagement de celles-ci. On notera qu'il est possible que les deux moyens pour l'accrochage des fils releveurs 20 ou 21, soient autres qu'une section rectiligne 42 ou 52, par exemple une boucle ou analogue, à spires non jointives pour permettre d'y faire pénétrer le fil et de l'y retenir. Il est toutefois recommandé que l'un de ces deux moyens soit une section rectiligne, pour favoriser le maintien du dispositif 1 dans un plan perpendiculaire aux fils. En référence maintenant aux figures 4 , 5 et 6, on peut voir un autre mode de réalisation 6 du dispositif de guidage de fils dits releveurs selon l' invention. Ce dispositif 6 se présente également sous la forme d'un fil de métal plié, qui de préférence consiste en un métal inoxydable de qualité ressort. Il comporte également un pliage en forme de boucle 60 comprenant une ouverture centrale 61 destinée au passage du fil de palissage 2. La boucle 60 présente les mêmes caractéristiques que la boucle 10 du dispositif 1, afin une mise en place sur le fil 2 par une approche latérale alors que ce dernier est tendu. De la boucle 60 s'étend un brin rectiligne 7 dont l'extrémité 70 présente d'une part un pli 71 à angle droit qui génère une section rectiligne 72 parallèle à l'axe de l'ouverture centrale 61 de la boucle 60, et d'autre part un pli 73 à angle droit pour former un segment rectiligne 74 perpendiculaire au plan formé par le brin 7 et la section rectiligne 72. Le segment 74 comporte en extrémité un pliage 75 en forme de flèche, s'étendant dans un plan perpendiculaire à l'axe de l'ouverture 61 de la boucle 60. Ce pliage 75 en forme de flèche présente du côté du segment 74 deux zones rétentrices 76 et 77, positionnées respectivement au-dessus et en dessous du segment 74, et en extrémité une partie triangulaire 78 déviatrice. Le dispositif 6 comporte de plus, s'étendant depuis la boucle 60, dans la direction opposée au brin 7 et sensiblement dans l'alignement de ce dernier, un brin 62 muni à son extrémité d'une boucle 63 semblable à la boucle 60. On notera que dans une variante de ce dispositif 6, la boucle 60 en constitue l'extrémité inférieure, c'est-à-dire qu'il n'y a pas de brin 62. De manière analogue au dispositif 1, le dispositif 6 est destiné à être monté pivotant sur le fil de palissage 2 par l'intermédiaire de la boucle 60, tandis qu'un fil releveur 20 est entortillé sur la section rectiligne 72, et que le pliage 75 en forme de flèche permet de crocheter l'autre fil releveur. On peut ainsi rapprocher et crocheter les deux fils releveurs au moyen de dispositifs 6 placés de proche en proche. De manière avantageuse, les dispositifs 6 peuvent en alternance, être positionnés l'un d'un côté et l'autre de l'autre de la végétation, comme cela est représenté sur la figure 4. Avec ce mode de réalisation, il est possible de guider des fils releveurs de pied 22, tel que représenté sur les figures 5 et 6, en utilisant les boucles 63. Par le basculement des dispositifs 6, en pivotement sur le fil 2, on peut simultanément resserrer les fils releveurs hauts et bas, ou simultanément les resserrer. On peut remarquer par ailleurs la présence sur le brin 7, dans la région médiane de celui-ci, d'une double boucle 79 destinée à permettre le maintien d'un fil releveur intermédiaire 23, représenté sur les figures 5 et 6, cette double boucle 79 étant conformée pour permettre un engagement du fil 23 alors que celui-ci est tendu en inclinant celui-ci pour l'engager entre les deux boucles de cette double boucle 79. Un tel dispositif est réservé à des cultures particulières, dans lesquelles la végétation est abondante, et s'étend sur une bonne hauteur. De manière analogue au dispositif 1, le dispositif 6, ainsi que ses variantes précédemment évoquées, est de préférence associé à des moyens aptes à limiter son angle de pivotement sur le fil de palissage 2, et qui peuvent consister en des chaînettes ou analogues attachées à des piquets ou à des fils fixes. On peut également envisager que le dispositif selon l'invention, quel que soit son mode de réalisation, présente un pliage supplémentaire permettant de créer un élément d'appui apte à coopérer avec un piquet proche pour limiter le pivotement. En référence aux figures 7a, 7b, 7c t 7d, on peut voir des variantes du dispositif de guidage selon l'invention, qui diffèrent de ceux précédemment décrits dans la manière dont sont ou non réalisés les pliages 60, 75, 63 et 79. Les pliages 75 sont notamment à accrochage uniquement par le dessous, tandis que les boucles 60 sont oblongues. On notera que ces variantes sont également applicables au dispositif 1. Le dispositif selon l'invention peut également être associé à des moyens de fixation des fils releveurs aux piquets de tête, et qui peuvent être de conception analogue. Un tel moyen de fixation peut se présenter sous la forme d'un dispositif 1 disposé dans un plan horizontal, et présentant d'une part, en remplacement de la boucle 10, un anneau destiné à être enfilé sur un piquet de tête, et d'autre part au niveau des extrémités 40 et 50 un anneau pour la fixation des extrémités des fils releveurs, tandis que les extrémités 45 et 55 sont conformées pour un accrochage mutuel . Les figures 8a et 8b représentent un mode de réalisation 8 du dispositif selon l'invention qui permet, outre le guidage en écartement des fils releveurs, le réglage de la tension de ces derniers . Ce dispositif 8 est également réalisé par pliage d'un fil métallique de qualité ressort, il comporte deux brins 80 et 81, reliés entre eux par une zone intermédiaire 82 et faisant entre eux un certain angle. Les extrémités libres des brins respectivement 80 et 81 présentent chacune une boucle ou analogue, respectivement 83 et 84, permettant l'accrochage de l'extrémité d'un fil releveur, et l'une d'elles comporte un crochet 85, destiné au crochetage du fil releveur fixé à l'autre brin après rapprochement des deux brins 80 et 81. La zone intermédiaire 82 relie les deux brins 80 et 81 à un anneau ou analogue 86 destiné à la solidarisa ion du dispositif 8 à un piquet de tête, et est constituée de deux enroulements coaxiaux 87 et 88, qui forment ressorts en sorte d'autoriser une déformation et un rappel des brins 80 et 81 par rapport à l'anneau ou analogue 86 dans un plan sensiblement perpendiculaire à celui dans lequel s'effectue le déplacement des brins 80 et 81 l'un par rapport à l'autre. Ce dispositif assure donc la tension des fils releveurs, tout en autorisant leur écartement ou leur maintien l'un à côté de l'autre. Il est bien entendu possible d'utiliser des éléments présentant d'autres formes pour atteindre le but recherché. Tel qu'il est décrit précédemment, le dispositif de guidage selon l'invention est mis en œuvre manuellement, ce qui est particulièrement aisé. Il convient toutefois de noter que le relevage des fils 20 et 21 peut être réalisé de manière mécanique tout aussi aisément, notamment au travers du dispositif 9 représenté sur les figures 9 et 10. Ce dispositif 9 comprend essentiellement deux cylindres 90 et 91 d'axes verticaux, portés par bâti 92, et destinés à être déplacés de part et d'autre du rang de vigne à traiter en roulant sur les fils releveurs 20 et 21. Les cylindres 90 et 91 sont constitués d'une armature 93 comprenant en périphérie uniquement des génératrices 94 largement espacées. Les cylindres 90 et 91 sont par ailleurs prévus, par l'intermédiaire du bâti 92, mobiles en rappel l'un vers l'autre, et sont associés à des. moyens déflecteurs 95 disposés à l'avant du bâti 92. En pratique, le dispositif 9 est déplacé sur le rang de vigne à traiter, les déflecteurs 95 recentrent la végétation, les cylindres 90 et 91 roulent sur les fils releveurs 20 et 21, et les rapprochent l'un de l'autre suffisamment pour permettre leur accrochage par les pliages 45, 55 ou 75 des dispositifs de guidage 1 ou 6, non représentés, l'architecture aérée des cylindres 90 et 91 permettant à ces pliages 45, 55 ou 75 de traverser les plans verticaux contenant les fils releveurs 20 et 21. On notera que le dispositif 9, et plus exactement le bâti 92, peut être porté par une poutre transversale 96 qui en porte d'autres pour permettre le relevage simultané de plus d'un rang de vigne. DEVICE FOR GUIDING LIFTING WIRES USED IN THE FIELD OF TRAPPING IN ARBORICULTURE AND VITICULTURE, AND DEVICE FOR ITS IMPLEMENTATION. The present invention relates, in the field of trellising in arboriculture and viticulture, a device for guiding wires called lifters. During the growth of the vegetation, the young shoots grow substantially vertically, and the foliage develops so that after a certain time this vegetation tends to fall back under the effect of its own weight. In order to remedy this problem, it is known practice to train this vegetation, which consists in binding these rods to trellising wires extending between stakes. It is also known to use so-called lifting wires, placed on either side of the stakes, near the top of the latter, and between which the vegetation is intended to be contained. In the fall, after the pruning operation, the lifting wires are unhooked from the stakes, only to be hung up again in the spring during the trellising and lifting operation, which increases the leaf area, to promote the ripening of the grapes or the administration of treatment products for this vegetation. Such a lifting consists in bringing the lifting wires closer to each other on the vegetation and in keeping them tightened, in particular using staples arranged like jumpers over these two wires. To this end, devices are used which are capable of reversibly holding these so-called lifting wires, which consist of retentive grooves made on either side of the stake as described in documents DE 20 39 580 and US 2,011,716 , or in devices attached to the stake and comprising such grooves as described in document US Pat. No. 3,411,754. Devices are also known, usually called spacers, designed capable of being made integral with a stake and comprising two branches each extending on either side of said stake and having at their free end a ring in which the thread is threaded. Such devices are described in documents EP 0 876 756 and CH 685 187. The branches can take two extreme positions in which the wires are either spaced apart from one another, or tightened. The device of document CH 685 187 provides for manual intervention for the positioning, whether in one position or in the other, of each of the branches, advantageously, the spacer device described in document EP 0 876 756 is provided with 'a spring means allowing the automatic passage from the constricted position to the separated position as soon as the branches, the ends of which are provided capable of being held by a hooking means, are released. It will be noted that it is also frequent to use foot-lifting wires, making it possible to maintain the low vegetation of the vine, and which are equipped with spacer devices similar to those previously described. These various devices are tedious to use, moreover, they require a particular adaptation of the planting in the sense that it is not possible, unless major modifications are made, to implement them on existing facilities. This drawback is, in most cases, linked to the fact that the existing devices are of use in relation to a particular configuration of the spike. Another drawback of existing devices is that they are usually made integral with the stake by fixing at a determined height. This only allows a lifting of the vegetation at a determined height but does not in any way make it possible to ensure a lifting in stages and accompanying the growth of the vegetation. The object of the present invention is to remedy these various drawbacks by proposing a device for guiding so-called take-up wires which has the great advantage of being independent of the type of stakes used, and which is installed without any modification of the existing installation. The lifter wire guiding device according to the invention is of the type made of metal wire shaped by bending, and it is essentially characterized in that it comprises, on the one hand, a bending in the form of a loop; and on the other hand at one end of a strand extending from said loop-shaped folding, a first folding adapted to allow the attachment of a take-up wire, extended, in the extreme end, by a second folding forming a hook , suitable for allowing the picking of the second take-up wire after bringing together the two said take-up wires. The loop is intended to allow the attachment of the device on a stake with the possibility of pivoting on the latter, or to allow, by a lateral approach, its attachment to a trellising wire, and to allow, after attachment, its free pivoting on said trellising wire. This device is particularly advantageous when it is intended to be hung on a trellising wire, since it does not require a stake, and it is thus possible to use as many as desired between two posts. According to an additional characteristic of the device according to the invention, when it is intended to be hung on a wire, the folding in the form of a loop consists of a winding over more than 360 ° with an overlapping zone of the turns where these are not joined to allow the engagement of the trellising wire. According to another additional characteristic of the device according to the invention, the first folding able to allow the attachment of a take-up wire consists of a succession of two folds at right angles to form on the one hand a section parallel to the axis of passage of the trellising wire in the bend in the form of a loop, to allow the kinking of the take-up wire, and two radial segments in said section and intended to keep said wire twisted. According to another additional characteristic of the device according to the invention, the second folding forming a hook, capable of allowing the second take-up wire to be hooked consists of a folding to form a hook which is inscribed in a plane perpendicular to the axis of passage of the trellising wire in the loop-shaped folding. According to a particular embodiment of the device according to the invention, the second folding forming a hook is shaped in the shape of an arrow having two retentive zones and at the end a triangular deviating part so as to allow the picking of the take-up wire from above or by the below. According to a first particular embodiment of the device according to the invention, it comprises two rectilinear strands extending from the fold in the form of a loop at an angle to one another, and each of which is provided with its end, a first and a second folding for the attachment of the two lifters. According to a variant of the first embodiment of the device according to the invention, the ends of the straight strands are folded symmetrically with respect to one another. According to a second particular embodiment of the device according to the invention, it comprises two rectilinear strands extending from the fold in the form of a loop being aligned with respect to each other, one being provided at its end first and second folds for hooking and hooking two lifting wires, while the other is provided at its end with means, similar to said loop-shaped folding, for hooking a foot lifter. According to an additional characteristic of the second particular embodiment of the device according to the invention, the rectilinear strand extending between the folding in the form of a loop and the first and the second folding for the hooking and hooking of two lifting wires, comprises in its central region a double loop intended for the attachment of an intermediate take-up wire. In order to facilitate the implementation of the device according to the invention, whatever its embodiment, it is advantageously provided that the take-up wires have a certain elasticity over their length, which is obtained by having, in one or more locations , expandable elements such as springs. Such elements can be secured to each of the ends of the wires, and serve to hook them to the head posts. These elements may consist of elements in the form of staples coming from the bending of a bent metal wire, which preferably consists of a stainless steel of spring quality, elastically deformable and having at the ends hooking means, for the one with a wire and the other with a stake. It is also possible to provide a staple which can be secured to a stake and to which the ends of the lifting wires can be hung, making it possible to hold the wires in two positions, apart or close together, and having elastic extension properties in the longitudinal direction of said wires. son. The present invention also relates to a device for the implementation of the guide device according to the invention, and more particularly during the lifting operation. This implementation device is essentially characterized in that it comprises two cylinders with vertical axes, of perforated cylindrical surface, carried by a frame intended to be moved parallel to the vegetation, recalled towards each other, suitable to roll on the take-up wires on either side of them by exerting a pressure to bring them together until allowing picking, said perforated cylindrical surface being for this purpose designed capable of allowing folds forming hook to penetrate the interior of said cylinders for hooking said son. The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents several non-limiting embodiments. In the accompanying drawing: - Figure 1 shows a schematic front elevation view of a first embodiment of the device according to the invention. - Figure 2 shows a schematic side elevational view of the same embodiment. - Figure 3 shows a schematic top view of the same embodiment. - Figure 4 shows a schematic front elevation view of a second embodiment of the device according to the invention. - Figure 5 shows a schematic side elevational view of the same embodiment. - Figure 6 shows a schematic top view of the same embodiment. - Figures 7a, 7b, 7c and 7d show schematic plan views of variants of the device according to the invention. - Figure 8a shows a schematic profile view of a particular embodiment of the device according to the invention. - Figure 8b shows a schematic plan view of this particular embodiment. - Figure 9 shows a schematic plan view of a device for the implementation of the device according to the invention. - Figure 10 shows a partial schematic in elevation of the same device. With reference to FIGS. 1, 2 and 3, one can see a first embodiment 1 of the device for guiding so-called take-up wires according to the invention. As shown in FIG. 3, the device 1 is intended to cooperate with, on the one hand, a trellising wire 2 carried by a stake P which it crosses, and, on the other hand, two take-up wires 20 and 21 which are not integral with the stake P . The device 1 is in the form of a folded metal wire, which preferably consists of a spring-quality stainless metal. It has in its central region a fold in the form of a loop 10 comprising a central opening 11 intended for the passage of the trellising wire 2. The loop 10 is shaped to allow the positioning of the device 1 on the wire 2 by a lateral approach then that it is stretched, for this purpose it consists of a winding greater than 360 ° to allow the creation of the central opening 1, while in the overlapping zone of the turns the latter are not contiguous to allow engagement of the wire 2. In practice, the device 1 is brought close to the wire 2 which is engaged between the two turns of the loop 10, then by making the device 1 make a quarter turn, the wire 2 is maintained in the central opening 11. From the loop 10 of the device 1 extend two rectilinear strands 4 and 5 making between them a certain angle, in this case of the order of 60 °, and whose ends are shaped for the attachment of the take-up wires 20 and 21 The end tee 40 of strand 4 thus has on the one hand a fold 41 at a right angle which generates a rectilinear section 42 parallel to the axis of the central opening 11 of the loop 10, and on the other hand a fold 43 at right angles to form a rectilinear segment 44 perpendicular to the plane formed by the strand 4 and the rectilinear section 42. As can be seen more precisely in FIG. 3, the take-up wire 20 is intended to be twisted on the rectilinear section 42, the rectilinear segment 44 as well as the strand 4 at the fold 41 helping to keep the wire 20 twisted. The segment 44 comprises at the end a folding 45 in the form of an arrow, extending in a plane perpendicular to the axis of the opening 11 of the loop 10. This folding 45 in the form of an arrow has two zones on the side of the segment 44 retentives 46 and 47, positioned respectively above and below the segment 44, and at the end a deflecting triangular part 48. In the same way, the strand 5 comprises at its end 50, a fold 51 at a right angle, a straight section 52, a fold 53 at a right angle, a straight segment 54, at the end a fold 55 in the form of an arrow having two zones retentrices 56 and 57, and a triangular portion 58 deflecting. The strand 5 is, however, symmetrical to the strand 4 in the sense that the fold 41 is produced in the opposite direction to the fold 51. The rectilinear section 52 is of course intended for the kinking of the take-up wire 21, while the rectilinear segment 54 as well as the strand 5 at the fold 51 help to keep the wire 21 twisted. It will be noted that the kinking of the wires 20 and 21 on the straight sections, respectively 42 and 52, due to the tightening of the sections by the wires 20 and 21, contributes to keeping the device 1 in a fixed position relative to these wires 20 and 21, and preferably, depending on the way in which it is installed, in a plane perpendicular to these wires 20 and 21. In the configuration shown in FIGS. 1, 2 and 3, the strands 4 and 5 are separated, this is that is to say that they keep apart the lifting wires 20 and 21 to allow the growth of the vegetation. When it is necessary to tighten the vegetation, the lifting wires 20 and 21 are raised, which, as shown in broken lines in FIG. 1, is easily achieved by bringing them together, for example by grasping the straight sections 42 and 52 of the device 1, and by hooking, on the one hand, the wire 20 with the arrow-shaped folding 55, the wire 20 wedging in one of the retaining zones 56 and 57 depending on whether it passes over or in below the deflecting triangular part 58, and on the other hand the take-up wire 21 with the bend 45 in the form of an arrow, the wire 21 wedging in one of the retaining zones 46 and 47 depending on whether it passes over or below the deflecting triangular part 48. The release of the take-up wires 20 and 21 is carried out by operating the reverse maneuver, that is to say by disengaging them folds 45 and 55 in the form of an arrow, and by a spring effect the two strands 4 and 5 open. It will be noted that it may be necessary to add to the device 1 means making it possible to limit the movement of the take-up wires 20 and 21, in order to prevent the devices 1 which equip _ a vineyard from rocking on one side with the vegetation. Such means may for example consist of chains or the like, of selected length and connecting each of the wires 20 and 21 to a stake P or to a fixed trellising wire such as wire 2 or another similar. The device 1 according to the invention is independent of the type of stake used to support the trellising wire 2, and it is adaptable to the wires 2, 20 and 21, when these are already in place. This device can therefore easily be used on existing installations without refitting them. Note that it is possible that the two means for hooking the take-up wires 20 or 21, are other than a rectilinear section 42 or 52, for example a loop or the like, with non-contiguous turns to allow it to be done penetrate the wire and hold it there. It is however recommended that one of these two means is a rectilinear section, to favor the maintenance of the device 1 in a plane perpendicular to the wires. With reference now to FIGS. 4, 5 and 6, one can see another embodiment 6 of the device for guiding yarns called levers according to the invention. This device 6 is also in the form of a folded metal wire, which preferably consists of a stainless steel of spring quality. It also includes a folding in the form of a loop 60 comprising a central opening 61 intended for the passage of the trellising wire 2. The loop 60 has the same characteristics as the loop 10 of the device 1, in order to be placed on the wire 2 by a lateral approach while the latter is stretched. From the loop 60 extends a rectilinear strand 7, the end 70 of which has on the one hand a fold 71 at a right angle which generates a rectilinear section 72 parallel to the axis of the central opening 61 of the loop 60, and on the other hand a fold 73 at a right angle to form a rectilinear segment 74 perpendicular to the plane formed by the strand 7 and the rectilinear section 72. The segment 74 has at its end a folding 75 in the form of an arrow, extending in a plane perpendicular to the axis of the opening 61 of the loop 60. This folding 75 in the form of an arrow has, on the side of the segment 74, two retentive zones 76 and 77, positioned respectively at above and below the segment 74, and at the end a deflecting triangular part 78. The device 6 further comprises, extending from the loop 60, in the direction opposite to the strand 7 and substantially in alignment with the latter, a strand 62 provided at its end with a loop 63 similar to the loop 60. It will be noted that in a variant of this device 6, the loop 60 constitutes its lower end, that is to say that there is no strand 62. In a similar manner to device 1, device 6 is intended to be pivotally mounted on the trellising wire 2 via the loop 60, while a take-up wire 20 is twisted on the straight section 72, and that the folding 75 in the form of an arrow makes it possible to crochet the another take-up wire. It is thus possible to bring together and crochet the two take-up wires by means of devices 6 placed step by step. Advantageously, the devices 6 can alternately be positioned one on one side and the other on the other side of the vegetation, as shown in FIG. 4. With this embodiment, it is possible to guide the foot take-up wires 22, as shown in FIGS. 5 and 6, using the loops 63. By the tilting of the devices 6, by pivoting on the wire 2, it is possible to tighten the top and bottom take-up wires simultaneously, or simultaneously tighten them. We can also note the presence on the strand 7, in the central region thereof, of a double loop 79 intended to allow the maintenance of an intermediate take-up wire. 23, shown in FIGS. 5 and 6, this double loop 79 being shaped to allow engagement of the wire 23 while the latter is stretched by tilting the latter to engage it between the two loops of this double loop 79. A such a device is reserved for particular crops, in which the vegetation is abundant, and extends over a good height. Analogously to the device 1, the device 6, as well as its variants previously mentioned, is preferably associated with means capable of limiting its pivoting angle on the trellising wire 2, and which can consist of chains or the like attached to stakes or fixed wires. It is also conceivable that the device according to the invention, whatever its embodiment, has an additional folding making it possible to create a support element capable of cooperating with a nearby stake to limit pivoting. With reference to FIGS. 7a, 7b, 7c t 7d, one can see variants of the guiding device according to the invention, which differ from those previously described in the way in which the folds 60, 75, 63 and 79 are produced or not. The folds 75 are in particular hooked only from below, while the loops 60 are oblong. It will be noted that these variants are also applicable to the device 1. The device according to the invention can also be associated with means for fixing the lifting wires to the head stakes, and which can be of similar design. Such a fixing means can be in the form of a device 1 arranged in a horizontal plane, and having on the one hand, in replacement of the loop 10, a ring intended to be threaded on a head post, and d on the other hand, at the ends 40 and 50, a ring for fixing the ends of the take-up wires, while the ends 45 and 55 are shaped for mutual attachment. Figures 8a and 8b show an embodiment 8 of the device according to the invention which allows, in addition to guiding spacing of the lifting wires, adjusting the tension of the latter. This device 8 is also produced by folding a metal wire of spring quality, it comprises two strands 80 and 81, connected together by an intermediate zone 82 and forming between them a certain angle. The free ends of the strands respectively 80 and 81 each have a loop or the like, respectively 83 and 84, allowing the attachment of the end of a take-up wire, and one of them comprises a hook 85, intended for picking take-up wire fixed to the other strand after the two strands 80 and 81 have been brought together. The intermediate zone 82 connects the two strands 80 and 81 to a ring or the like 86 intended for securing the device 8 to a head post, and consists of two coaxial windings 87 and 88, which form springs so as to allow a deformation and a return of the strands 80 and 81 relative to the ring or the like 86 in a plane substantially perpendicular to that in which the displacement of the strands 80 and 81 relative to each other. This device therefore ensures the tension of the take-up wires, while allowing them to be separated or kept one next to the other. It is of course possible to use elements having other shapes to achieve the desired goal. As described above, the guiding device according to the invention is implemented manually, which is particularly easy. It should however be noted that the lifting of the wires 20 and 21 can be carried out mechanically just as easily, in particular through the device 9 shown in FIGS. 9 and 10. This device 9 essentially comprises two cylinders 90 and 91 with axes vertical, carried by frame 92, and intended to be moved on either side of the row of vines to be treated by rolling on the lifting wires 20 and 21. The cylinders 90 and 91 consist of a frame 93 comprising at the periphery only generators 94 widely spaced. The cylinders 90 and 91 are moreover provided, by means of the frame 92, movable in return towards one another, and are associated with. deflector means 95 disposed at the front of the frame 92. In practice, the device 9 is moved onto the row of vines to be treated, the deflectors 95 refocus the vegetation, the cylinders 90 and 91 roll on the lifting wires 20 and 21, and bring them together sufficiently to allow them to be hooked by the folds 45, 55 or 75 of the guide devices 1 or 6, not shown, the ventilated architecture of the cylinders 90 and 91 allowing these folds 45, 55 or 75 to cross the vertical planes containing the lifting wires 20 and 21. It will be noted that the device 9, and more precisely the frame 92, can be carried by a transverse beam 96 which carries others to allow the simultaneous lifting of more 'a row of vines.
