Abstract

Attachment adapted in particular for the training of vines in the general shape of a rectangular plate comprising two slots 1, the width of which is sufficient to receive in each case a training wire, said slots 1 being closed at their free ends 2 and opening at their intersection with an opening 3 for carrying out the insertion of the training wires, characterised in that it comprises one or more visible 4, 5 or invisible 6, 7 weakening zones in the material of the attachment creating the beginning of a break between the free end 2 of a slot 1 and at least one edge of the attachment. The attachment according to the invention can thus deteriorate naturally in the course of time.

Description

Au printemps, les rameaux fructifères de la vigne se développent anarchiquement. Afin de faciliter le travail mécanique et de ne pas compromettre la récolte, au mois de juin, on ramène ces brins vers le haut, en les enserrant entre les deux fils dits de palissage. Entre les piquets, ces fils qui passent de part et d'autre des rameaux du mdme cep, sont reliés par des attaches. In spring, the fruiting branches of the vine develop anarchically. In order to facilitate mechanical work and not to compromise the harvest, in June, these strands are brought upwards, by enclosing them between the two so-called trellising wires. Between the stakes, these wires which pass on either side of the branches of the same vine, are connected by ties.

Les attaches utilisées jusqu'à présent pour lé palissage des vignes, sont constituées d'une plaque de matière munie de fentes ou de trous d'un diamètre légèrement supérieur à celui d'un fil de palissage. Ces attaches sont posées vers la fin du printemps et retirées après la vendange. La pose se fait manuellement ou mécaniquement, mais l'enlèvement reste manuel, et demande beaucoup de temps. The fasteners used until now for the training of vines, consist of a material plate provided with slots or holes with a diameter slightly larger than that of a trellising wire. These ties are placed in late spring and removed after the harvest. The installation is done manually or mechanically, but the removal remains manual, and requires a lot of time.

La présente invention a pour objet une attache permettant de relier deux fils, notamment pour le palissage des vignes dont la mise en place est la mdme que dans les méthodes utilisées actuellement, mais où le retrait est automatisé par la détérioration de l'attache. The subject of the present invention is a fastener making it possible to connect two wires, in particular for training the vines, the installation of which is the same as in the methods currently used, but where the withdrawal is automated by the deterioration of the fastener.

On a décrit ci-près, à titre d'exemple non limitatif, trois méthodes de réalisation de l'attache selon l'invention avec référence au dessin annexé dans lequel
- la figure 1 est une vue en élévation de l'attache
conçue pour une casse mécanique.Three methods of producing the fastener according to the invention have been described below, by way of non-limiting example, with reference to the appended drawing in which
- Figure 1 is an elevational view of the fastener
designed for mechanical breakage.

- la figure 2 est une vue semblable à la figure 1
avec mise en évidence d'amorces de rupture.- Figure 2 is a view similar to Figure 1
with evidence of breakthroughs.

Telle qu'elle est représentée à la figure 1, l'attache qui est par exemple en matière plastique, comporte deux fentes 1, dont l'épaisseur est supérieure au diamètre des fils de palissage. L'une des extrémités de chaque fente possède un arrondi 2 où viendra se bloquer un fil, l'autre extrémité de chaque fente débouche par une même ouverture 3 . Sous l'effet d'un choc, ou sous l'effet d'une tension accentuée des fils, l'attache se détériore. As shown in Figure 1, the fastener which is for example of plastic, has two slots 1, the thickness of which is greater than the diameter of the trellis wires. One end of each slot has a rounded 2 where a wire will hang, the other end of each slot opens out through the same opening 3. Under the effect of a shock, or under the effect of an accentuated tension of the threads, the fastener deteriorates.

Dans le cas où on emploie un matériau plus résistant, pour la conception de l'attache, on peut diminuer l'épais- seur de la matière ou bien, on peut placer une ou plusieurs amorces de rupture visibles figure 2,4,5, ou invisibles 6,7 qui faciliteront la détérioration de l'at ache. In the case where a more resistant material is used, for the design of the fastener, one can reduce the thickness of the material or else, one can place one or more visible incipient fractures figure 2,4,5, or invisible 6,7 which will facilitate the deterioration of the attachment.

L'amorce de rupture est un affaiblissement dû à la forme de l'attache ou à la méthode de fabrication ou à la matière utilisée. L'affaiblissement dû à la forme consiste à diminuer la largeur de matière entre l'emplacement du fil et la paroi extérieure de l'attache, figure 2, points 6,7. L'affaiblissement dû à la méthode de fabrication peut laisser appaire une ou plusieurs amorces de rupture matérialisées pau un enlèvement de matière où l'attache doit se détériorer, figure 2, point 4,5. The initiation of failure is a weakening due to the shape of the fastener or the manufacturing method or the material used. The weakening due to the form consists in decreasing the width of material between the location of the wire and the external wall of the fastener, figure 2, points 6,7. The weakening due to the manufacturing method may give rise to one or more incipient fractures materialized by a removal of material where the fastener must deteriorate, Figure 2, point 4.5.

L'affaiblissement dû à la matière utilisée peut ne pas se remarquer, car dans le cas de matière plastique, on peut créer un défaut de moulage qui provoquera une fragilité à l'endroit choisi sur l'attache. Les amorces de rupture peuvent s'adapter'sur toutes les variantes d'attaches utilisée actuellement, notamment pour le palissage des vignes. The weakening due to the material used may not be noticed, because in the case of plastic, one can create a molding defect which will cause brittleness at the chosen location on the fastener. The primers of rupture can be adapted to all the variants of ties currently used, in particular for the training of vines.

On peut utiliser aussi des matériaux qui peuvent se détériorer seul, notamment des matériaux non stabilisés qui par leur vulnérabilité à certains agents extérieurs, climatiques, biologiques, chimiques, physiques ou autres,peuvent se détériorer. Dans ce cas, l'attache peut ne pas présenter de spécificité visuelle, montrant son aptitude à se détériorer. One can also use materials which can deteriorate alone, in particular unstabilized materials which by their vulnerability to certain external, climatic, biological, chemical, physical or other agents, can deteriorate. In this case, the fastener may not have any visual specificity, showing its ability to deteriorate.

Après emploi, l'attache est détériorée, elle tombe sur le sol et peut être ramassée si la matière utilisée est polluante. Elle peut être laissée si la matière n'est pas polluante. After use, the fastener is damaged, it falls on the ground and can be picked up if the material used is polluting. It can be left if the material is not polluting.

Il va de soi que la présente invention ne doit pas être considérée comme limitée à l'exemple d'attache citée, mais en couvre au contraire toutes les variantes. It goes without saying that the present invention should not be considered as limited to the example of attachment cited, but on the contrary covers all variants thereof.
