Abstract
Description
Tendeur pour fil de palissage.Tensioner for trellising wire.
L'invention se situe principalement dans le domaine de la viticulture et concerne plus précisément un tendeur de fil de palissage destiné à être monté sur un poteau bout de course. The invention is mainly located in the field of viticulture and more specifically relates to a trellis wire tensioner intended to be mounted on a post limit switch.
Ces fils de palissage sont des fils de fer qui doivent relever et retenir les sarments de vigne et pour cela ils doivent être tendus entre des poteaux d'extrémité. These trellising wires are iron wires which must raise and retain the vine shoots and for this they must be stretched between end posts.
Les tendeurs utilisés à cette fin sont souvent réalisés comme des enrouleurs à tambour sur lesquels le fil à tendre s'enroule par rotation, un dispositif anti-retour de blocage du type à clavettes ou à dents bloquant l'enrouleur quand la tension voulue est obtenue. La mise en oeuvre de ces enrouleurs exige une certaine force de la part de l'utilisateur. En outre leur longueur d'enroulement est limitée et ils sont sensibles à la rouille et par conséquent d'un réemploi difficile. Pour éviter ces inconvénients, on connaît des tendeurs utilisant une tige métallique pliée selon plusieurs plans.The tensioners used for this purpose are often made as drum winders on which the soft wire is wound by rotation, a non-return locking device of the key or tooth type blocking the reel when the desired tension is obtained . The implementation of these reels requires a certain force on the part of the user. In addition, their winding length is limited and they are susceptible to rust and therefore difficult to reuse. To avoid these drawbacks, tensioners are known using a metal rod bent in several planes.
On enroule le fil sur la tige, dont les extrémités s'immobilisent ensuite sur le fil tendu. The wire is wound on the rod, the ends of which are then immobilized on the stretched wire.
Il existe aussi des systèmes à coulisses pouvant se déplacer sur un fer en U monté sur un poteau, les coulisses se bloquant automatiquement sur ledit fer par l'effet de la traction du fil. Mais pour la mise en tension du fil, l'utilisateur doit exercer un effort important sur chaque coulisse pour la débloquer et la déplacer, effort inacceptable dans le cas de palissages longs. There are also sliding systems that can move on a U-shaped iron mounted on a post, the slides automatically locking on said iron by the effect of the traction of the wire. But for the tensioning of the wire, the user must exert a significant effort on each slide to unlock and move it, unacceptable effort in the case of long trellises.
La Demanderesse s'est donc attachée à concevoir et réaliser un tendeur de fil beaucoup plus simple à utiliser et à régler, qui n'est absolument pas fragile ni sensible à la rouille et qui de surcroît est de fabrication très simple, donc peu coûteux. The Applicant has therefore endeavored to design and produce a wire tensioner which is much simpler to use and adjust, which is absolutely not fragile or sensitive to rust and which, moreover, is very simple to manufacture, therefore inexpensive.
L'invention a donc pour objet principal un tendeur pour fil de palissage utilisant un fer en forme de U destiné à s' accrocher à un poteau de bout de course et des moyens de blocage de fil coulissant sur les branches du fer, tendeur selon lequel le fer en forme de U est réalisé partir d'une tige cannelée, le moyen de blocage sur chaque branche du fer étant constitué d'une plaquette qui est pourvue d'une part d'un orifice de diamètre un peu plus grand que celui de la tige grâce auquel elle est emmanchée sur ladite tige, et d'autre part d'au moins un trou dans sa moitié inférieure pour le passage du fil à tendre. The main object of the invention is therefore a tensioner for trellising wire using a U-shaped iron intended to hang on a limit post and means for blocking sliding wire on the arms of the iron, tensioner according to which the U-shaped iron is produced from a grooved rod, the blocking means on each branch of the iron consisting of a plate which is provided on the one hand with an orifice of diameter a little larger than that of the rod through which it is fitted on said rod, and on the other hand at least one hole in its lower half for the passage of the wire to be stretched.
Selon une variante de réalisation un second trou est prévu entre le trou inférieur et l'orifice d'emmanchement de la tige, sensiblement à mi-distance. According to an alternative embodiment, a second hole is provided between the lower hole and the fitting hole of the rod, substantially at mid-distance.
Avantageusement, les bords verticaux de la plaquette forment un arrondi au niveau de l'orifice supérieur, prolongeant les parties verticales. Advantageously, the vertical edges of the plate form a round at the level of the upper orifice, extending the vertical parts.
Selon une autre caractéristique de l'invention, sur l'extrémité de chaque branche du fer est emmanché un guide-fil muni d'un orifice pour le guidage du fil. According to another characteristic of the invention, on the end of each branch of the iron is fitted a wire guide provided with an orifice for guiding the wire.
D'autres caractéristiques particulières et avantages de l'invention ressortiront de la description qui va suivre d'un exemple non limitatif de réalisation dans lequel il est fait référence aux dessins annexés qui représentent
figure 1 une vue en perspective du tendeur
figure 2 une vue en plan à plus grande échelle de la plaquette
figure 3 une vue en perspective du tendeur en position d'utilisation.Other particular characteristics and advantages of the invention will emerge from the description which follows of a nonlimiting exemplary embodiment in which reference is made to the appended drawings which represent
Figure 1 a perspective view of the tensioner
Figure 2 a plan view on a larger scale of the plate
Figure 3 a perspective view of the tensioner in the use position.
On a représenté sur la figure 1 un tendeur de fils de palissage constitué de trois éléments essentiels. D'une part un fer 3 en forme de U réalisé à partir d'une tige cannelée de fabrication classique, du genre des tiges utilisées dans le béton armé, protégés contre l'oxydation ou en acier inoxydable. La tige est cintrée pour que sa partie arrondie puisse s'accrocher à un poteau de bout de course. FIG. 1 shows a tensioner for trellising wires made up of three essential elements. On the one hand, a U-shaped iron 3 produced from a fluted rod of conventional manufacture, of the kind of rods used in reinforced concrete, protected against oxidation or made of stainless steel. The rod is curved so that its rounded part can hang on a limit post.
Elle peut se déplacer verticalement sur ledit poteau.It can move vertically on said post.
D'autre part, sur chacune des branches du fer 3 est engagée une plaquette d'accrochage du fil à tendre, réalisée en acier inoxydable désignée dans son en*+semble par la référence 1 et représentée plus en détail à la figure 2. En partie haute la plaquette 1 est pourvue d'un orifice 10 de diamètre un peu plus grand que celui de la tige cannelée constituant le fer grâce auquel la plaquette est enfilée sur la tige. Cet orifice se situe dans la moitié supérieure de la plaquette. Dans la moitié inférieure est prévu un trou 11 pour le passage du fil.On the other hand, on each of the branches of the iron 3 is engaged a plate for hanging the soft wire, made of stainless steel designated in its in * + appears by the reference 1 and shown in more detail in FIG. 2. In upper part the plate 1 is provided with an orifice 10 of diameter a little larger than that of the grooved rod constituting the iron by which the plate is threaded on the rod. This hole is located in the upper half of the plate. In the lower half is provided a hole 11 for the passage of the wire.
L'orifice et le trou se situent sur le même plan vertical médian de la plaquette. The orifice and the hole are located on the same vertical median plane of the plate.
En variante, un autre trou 15 est prévu entre le trou 11 et l'orifice 10, sensiblement à mi-distance. As a variant, another hole 15 is provided between the hole 11 and the orifice 10, substantially at mid-distance.
Les bords verticaux 12 de la plaquette forment un arrondi au niveau de l'orifice supérieur prolongeant des parties verticales. Par contre les bords inférieurs 13 et supérieurs 14 sont droits. Cette partie centrale arrondie a pour objet de renforcer la rigidité de la plaquette entre les deux trous et l'orifice supérieur c'est-à-dire dans une zone soumise à forte contrainte où serait à craindre le pliage de la plaquette. The vertical edges 12 of the plate form a round at the level of the upper orifice extending from the vertical parts. On the other hand, the lower 13 and upper 14 edges are straight. The purpose of this rounded central part is to reinforce the rigidity of the plate between the two holes and the upper orifice, that is to say in an area subjected to high stress where the folding of the plate would be feared.
A l'extrémité de chaque branche du fer 3 est emmanché à force un guide fil 4 qui peut être réalisé en matière plastique rigide. At the end of each branch of the iron 3 is force fitted a wire guide 4 which can be made of rigid plastic.
Ce guide fil de forme ovoïde est percé d'un orifice supérieur 5 de diamètre égal à celui de la tige cannelée pour pouvoir se bloquer sur la tige. Le guide fil 4 qui s étend sous la tige porte aussi un autre orifice 6 en position basse pour le passage du fil. I1 a également une fonction de sécurité pour que l'utilisateur ne se blesse pas à l'extrémité des tiges. This ovoid-shaped wire guide is pierced with an upper orifice 5 of diameter equal to that of the grooved rod so as to be able to block on the rod. The wire guide 4 which extends under the rod also carries another orifice 6 in the low position for the passage of the wire. It also has a safety function so that the user does not injure himself at the end of the rods.
Selon une variante de réalisation non représentée, le guide fil serait une pièce métallique pinçant la tige, muni d'une fente destinée à recevoir le fil qui y serait introduit à force. Grâce à ce guide-fil on peut démonter le fil sans avoir à l'enlever de la plaquette. According to a variant embodiment not shown, the wire guide would be a metal piece pinching the rod, provided with a slot intended to receive the wire which would be forcefully introduced therein. Thanks to this wire guide, the wire can be disassembled without having to remove it from the plate.
On a représenté à la figure 3 le tendeur de la figure 1 monté sur un poteau de bout de course 16 et équipé des fils de palissage 2. FIG. 3 shows the tensioner of FIG. 1 mounted on a travel end post 16 and fitted with trellising wires 2.
Chaque fil de palissage 2 à tendre est engagé d'abord dans le trou 6 du guide fil 4 puis dans un trou de la plaquette 1, par exemple le trou inférieur 11. Ensuite le brin d'extrémité du fil fait retour à nouveau par le trou 6 pour être torsadé un peu plus loin sur la ligne (partie inférieure de la figure 3). Il peut aussi être torsadé entre la plaquette et le guide-fil (partie supérieure de la figure 3). Each trellising wire 2 to be stretched is engaged first in the hole 6 of the wire guide 4 then in a hole of the plate 1, for example the lower hole 11. Then the end strand of the wire returns again by the hole 6 to be twisted a little further on the line (lower part of figure 3). It can also be twisted between the plate and the wire guide (upper part of Figure 3).
Pour tendre le fil, il suffit à l'utilisateur de tirer sur la plaquette 1 en direction du poteau 16 en la maintenant en position verticale pour qu'elle puisse coulisser sur la tige cannelée du fer 3. Dès que la tension du fil 2 est obtenue, on relâche le plaquette 1 ; la traction que le fil exerce sur la base de la plaquette va tendre à incliner celle-ci. De ce fait au niveau de l'orifice 10 il y aura accrochage et immobilisation de la plaquette sur une cannelure de la tige 3 avec impossibilité de ripage. Pour débloquer le tendeur en vue d'effectuer une tension complémentaire ou au contraire détendre le fil, il suffit de ramener la plaquette en position verticale pour pouvoir la déplacer. To tension the wire, the user just has to pull on the plate 1 in the direction of the post 16 while keeping it in an upright position so that it can slide on the grooved rod of the iron 3 obtained, the plate 1 is released; the pull that the wire exerts on the base of the plate will tend to tilt it. Therefore at the orifice 10 there will be hooking and immobilization of the wafer on a groove of the rod 3 with impossibility of shifting. To release the tensioner in order to carry out additional tension or, on the contrary, relax the thread, it suffices to return the plate to the vertical position in order to be able to move it.
Le second trou 15 montré à la figure 2 peut être utilisé avantageusement pour l'enroulement d'un fil souple. The second hole 15 shown in Figure 2 can advantageously be used for winding a flexible wire.
De toute façon le choix d'utilisation de l'un ou l'autre des trous ou des deux trous s'offre à l'utilisateur en fonction des besoins.In any case, the user can choose to use one or the other of the holes or both holes according to the needs.
Enfin le fait que le fer en U puisse se déplacer veticalement sur le poteau permet un réglage aisé de la hauteur du fil. Finally, the fact that the U-shaped iron can move vetically on the post allows easy adjustment of the height of the wire.
