Description

La présente invention a pour objet un tendeur de fil destiné à être mis en oeuvre notamment dans la technique du palissage, spécialement dans les domaines de la viticulture, l'arboriculture, l'horticulture et autres. The present invention relates to a wire tensioner intended to be used in particular in the trellising technique, especially in the fields of viticulture, arboriculture, horticulture and others.

On sait que le palissage consiste à tendre des fils, généralement en fer galvanisé, pour contenir et guider la poussée de la végétation, et qu'il est nécessaire de pouvoir régler la tension desdits fils. We know that trellising consists in stretching wires, generally in galvanized iron, to contain and guide the growth of vegetation, and that it is necessary to be able to adjust the tension of said wires.

Les tendeurs utilisés actuellement sont tous constitués de la même manière, comportant un axe percé d'un orifice diamétral dans lequel est introduit le fil à tendre, la rotation sur lui-même dudit axe provoquant l'enroulement du fil sur ce dernier. Afin d'éviter le désenroulement du fil l'axe est muni d'un dispositif anti-retour généralement constitué d'une roue dentée et d'une clavette articulée. The tensioners currently used are all constituted in the same way, comprising an axis pierced with a diametrical orifice into which the wire to be stretched is introduced, the rotation on itself of said axis causing the winding of the wire on the latter. In order to avoid unwinding of the wire, the axis is provided with a non-return device generally consisting of a toothed wheel and an articulated key.

Ce type d'enrouleurs présentent toutefois des inconvénients, en ce sens que d'une part la longueur d'enroulement est très limitée et que d'autre part ils peuvent rouiller et gripper facilement, ce qui les rend inutilisables au bout d'un certain temps alors qu'il est parfois nécessaire d'avoir à retendre les fils. This type of reel, however, has drawbacks, in that on the one hand the winding length is very limited and on the other hand they can rust and seize easily, which makes them unusable after a certain time while it is sometimes necessary to have to tighten the threads.

La présente invention vise à remédier à ces inconvénients en proposant un tendeur de conception simple ne comportant aucune pièce mobile, et d'un coût de fabrication bien inférieur à celui des tendeurs actuellement existants. The present invention aims to remedy these drawbacks by proposing a tensioner of simple design comprising no moving parts, and of a manufacturing cost much lower than that of tensioners currently existing.

Le tendeur objet de la présente invention se caractérise essentiellement en ce qu'il est constitué d'une tige métallique cambrée comportant plusieurs plis, notamment un pli central en forme de U dont une branche est pliée dans le même plan à angle droit, l'autre branche, plus longue, étant pliée également à angle droit dans le même plan, en sorte que les deux brins s'étendent parallèlement, de chaque côté du U, dans un même plan mais dans des directions opposées. The tensioner object of the present invention is essentially characterized in that it consists of a cambered metal rod comprising several folds, in particular a central U-shaped fold of which a branch is folded in the same plane at right angles, the another branch, longer, being folded also at right angles in the same plane, so that the two strands extend parallel, on each side of the U, in the same plane but in opposite directions.

Conformément à l'invention, l'extrémité de chacun desdits brins est pliée à angle droit dans des plans parallèles perpendiculaires au plan de l'ensemble, puis à nouveau pliée en V dans chacun desdits plans, et ceci de manière que lesdits V soient ouverts l'un vers l'autre, mais disposés de part et d'autre du plan contenant les brins et le pli en U. According to the invention, the end of each of said strands is folded at right angles in parallel planes perpendicular to the plane of the assembly, then again folded in V in each of said planes, and this so that said V are open towards each other, but arranged on either side of the plane containing the strands and the U-fold.

Le tendeur selon l'invention s'utilise de la manière suivante : on engage le fil à tendre, qui est solidarisé par ses extrémités à deux piquets, dans le U central du tendeur, on fait tourner ce dernier de manière que le fil s'enroule autour dudit U, puis, une fois que l'enroulement est amorcé, on peut le poursuivre selon deux modes, soit autour du U, si on désire une longueur d'enroulement assez importante, soit autour de sa branche la plus longue, si on désire une longueur d'enroulement plus petite. Lorsque l'on a obtenu la tension désirée on engage le fil dans les plis en V, afin d'empêcher son désenroulement. The tensioner according to the invention is used in the following way: one engages the wire to be stretched, which is secured by its ends to two stakes, in the central U of the tensioner, one rotates the latter so that the wire s' wraps around said U, then, once the winding is started, it can be continued in two modes, either around the U, if you want a fairly large winding length, or around its longest branch, if a shorter winding length is desired. When the desired tension has been obtained, the thread is engaged in the V-folds to prevent it from unwinding.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

La figure unique du dessin annexé représente une vue en perspective d'un tendeur selon l'invention sur lequel est enroulé un fil. The single figure of the appended drawing represents a perspective view of a tensioner according to the invention on which a wire is wound.

Sur cette figure on peut voir que le tendeur 1 est constitué d'une tige cambrée 2 qui comporte un pli central 20 en U dont une branche 21 est plus longue que l'autre 22. In this figure it can be seen that the tensioner 1 consists of a cambered rod 2 which has a central fold 20 in a U, one branch 21 of which is longer than the other 22.

A l'extrémité de la branche 21 la tige 2 comporte un pli 23 à angle droit dans le même plan que le pli 20 en U, et à l'extrémité de la branche 22 un pli 24 également à angle droit et dans le même plan que le pli 20 en U, les brins 25 et 26 résultant de ces pliages s'étendant ainsi dans un même plan, parallelement, mais dans des directions opposées. At the end of the branch 21 the rod 2 has a fold 23 at a right angle in the same plane as the fold 20 in a U, and at the end of the branch 22 a fold 24 also at a right angle and in the same plane as the fold 20 in U, the strands 25 and 26 resulting from these folds thus extending in the same plane, parallel, but in opposite directions.

L'extrémité du brin 25 comporte un pli 27 à angle droit dans un plan perpendiculaire au plan contenant le pli 20 en U, et un second pli dans ce même plan, de manière à former un V 29. The end of the strand 25 comprises a fold 27 at right angles in a plane perpendicular to the plane containing the fold 20 in a U, and a second fold in this same plane, so as to form a V 29.

De la même manière le brin 26 comporte un pli à angle droit 28 et un pli en V 30, les plis en V 29 et 30 étant disposés de part et d'autre du plan contenant le pli en U 20 et les brins 25 et 26, et étant ouverts l'un vers l'autre.  In the same way the strand 26 has a right-angled fold 28 and a V-fold 30, the V-folds 29 and 30 being arranged on either side of the plane containing the U-fold 20 and the strands 25 and 26 , and being open towards each other.

Pour tendre un fil 4 il suffit de l'engager dans le pli en U 20 et de faire tourner le tendeur dans le sens de la flèche F, de manière que le fil 4 s'enroule soit autour du
U 20 soit autour de la partie 21' de la branche 21, si l'on désire une longueur d'enroulement plus petite.To tension a wire 4, simply engage it in the U-shaped fold 20 and rotate the tensioner in the direction of arrow F, so that the wire 4 is wound around the
U 20 is around the part 21 'of the branch 21, if a shorter winding length is desired.

Lorsque le fil 4 est suffisamment tendu il suffit de l'engager dans les plis en V 29 et 30 afin d'empêcher son désenroulement. When the wire 4 is sufficiently stretched, it suffices to engage it in the V-folds 29 and 30 in order to prevent it from unwinding.

Outre les avantages déjà exposés, le tendeur selon l'invention offre cet avantage supplémentaire que les deux plis en V qui constituent ses deux moyens d'ancrage sur le fil à tendre lui permettent de résister aux batteurs des machines à vendanger. D'autre part les deux modes d'enroulement du fil qu'il permet lui confèrent un avantage supplémentaire en autorisant un réglage facile et précis de la tension dudit fil. In addition to the advantages already explained, the tensioner according to the invention offers this additional advantage that the two V-folds which constitute its two anchoring means on the soft wire allow it to withstand the beaters of the harvesting machines. On the other hand, the two modes of winding the wire which it allows give it an additional advantage by allowing easy and precise adjustment of the tension of said wire.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.  It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
