Abstract
Description
La présente invention est relative à un élément tubulaire en matière plastique à structure réticulaire, utilisable notamment pour la réalisation de poches d'élevage de coquillages, en particulier les huîtres. The present invention relates to a tubular element of plastic material with a reticular structure, usable in particular for the production of shellfish farming bags, in particular oysters.
On utilise depuis de nombreuses années des poches ostréicoles en matière plastique à structure réticulaire à mailles carrées ou losanges constituées d'un élément tubulaire aplati apte à être fermé à ses extrémités. Plastic oyster bags with a reticular structure with square or diamond meshes have been used for many years and consist of a flattened tubular element capable of being closed at its ends.
Dans les parcs à huitres de telles poches sont disposées habituellement transversalement sur des supports appelés tables, constitués notamment de fers à béton longitudinaux parallèles espacés. In oyster beds such pockets are usually arranged transversely on supports called tables, made up in particular of spaced parallel longitudinal concrete bars.
Pour renforcer la rigidité en sens longitudinal des poches afin de les maintenir sur les tables on met généralement en place, dans les poches, le long de leurs bords longitudinaux, des éléments de renforcement tels que des tubes rigides.To reinforce the stiffness in the longitudinal direction of the pockets in order to keep them on the tables, reinforcing elements such as rigid tubes are generally placed in the pockets along their longitudinal edges.
Outre l'inconvénient de nécessiter de tels éléments de renforcement supplémentaires diminuant dans chaque poche l'espace disponible pour les huitres, les poches traditionnelles, par suite du manque de rigidité de la structure de l'élément tubulaire dont elles sont formées, présentent en cours d'utilisation une forme ovale très aplatie écrasant les huitres qu'elles contiennent. In addition to the drawback of requiring such additional reinforcing elements reducing in each pocket the space available for oysters, traditional pockets, due to the lack of rigidity of the structure of the tubular element of which they are formed, have in progress use a very flat oval shape crushing the oysters they contain.
Les poches traditionnelles présentent toutefois l'avantage de pouvoir être conditionnées en piles, à l'état aplati, réduisant ainsi le volume de l'ensemble des poches transportées. However, traditional bags have the advantage of being able to be packaged in stacks, in a flattened state, thus reducing the volume of all of the bags transported.
La présente invention se propose de réaliser un élément tubulaire, utilisable notamment pour la réalisation de poches ostréicoles, ajoutant à l'avantage qui vient d'être mentionné des poches traditionnelles la possibilité d'un meilleur étalement des huitres dans les poches en cours d'utilisation et conférant ainsi aux huitres des formes meilleures améliorant leur qualité. The present invention proposes to produce a tubular element, usable in particular for the production of oyster pockets, adding to the advantage which has just been mentioned of traditional pockets the possibility of better spreading of oysters in the pockets being use and thus giving the oysters better forms improving their quality.
L'élément tubulaire selon l'invention se caractérise essentiellement par le fait qu'il comprend, dans deux zones diamétralement opposées, au moins un repli sensiblement en forme de V dont l'arête de sommet est dirigée vers l'intérieur de l'élément. The tubular element according to the invention is essentially characterized by the fact that it comprises, in two diametrically opposite zones, at least one substantially V-shaped fold whose top edge is directed towards the interior of the element .
Le ou les replis ainsi formés constituent des soufflets permettant à l'élément tubulaire de passer d'une premiére configuration aplatie, pour le transport, à une seconde configuration déployée en cours d'utilisation conférant à la poche une forme sensiblement parallélépipédique. Les parties de transition entre les faces principales de l'élément tubulaire et les zones de celui-ci munies du ou des replis vers l'intérieur constituent en effet les aretes d'un parallélépipède sensiblement rectangle dont les petits cotés sont constitués par les zones déployables comportant le ou les replis. Ces arêtes ainsi que l'arête de sommet du ou de chaque repli constituent par ailleurs des régions longitudinales de rigidification de l'élément tubulaire. The fold or folds thus formed constitute bellows allowing the tubular element to pass from a first flattened configuration, for transport, to a second configuration deployed during use, giving the pocket a substantially rectangular shape. The transition parts between the main faces of the tubular element and the zones thereof provided with or folds inwardly constitute the edges of a substantially rectangular parallelepiped whose short sides are formed by the deployable zones comprising the fold or folds. These edges, as well as the top edge of the or each fold, also constitute longitudinal regions of stiffening of the tubular element.
Dans un mode de réalisation particulier dans lequel l'élément tubulaire présente des mailles losanges, il est avantageux de réaliser à proximité et dans les zones dans lesquelles doivent être réalisés les replis des filaments longitudinaux s'étendant parallèlement aux diagonales des mailles de l'élément tubulaire, les aretes des parties de transition entre les faces de l'élément tubulaire et les arêtes de fond du ou des replis étant avantageusement réalisées entre des filaments longitudinaux. In a particular embodiment in which the tubular element has diamond meshes, it is advantageous to produce near and in the zones in which the folds of the longitudinal filaments extending parallel to the diagonals of the meshes of the element must be produced. tubular, the edges of the transition parts between the faces of the tubular element and the bottom edges of the fold or folds being advantageously made between longitudinal filaments.
Grace à l'invention, on peut réaliser des poches ostréicoles qui présentent une structure sensiblement parallélépipédique en cours d'utilisation et dont les flancs latéraux une fois les replis déployés présentent une certaine rigidité empêchant les faces principales supérieure et inférieure de s'écraser contre l'autre et donc de provoquer l'aplatissement de la poche. Thanks to the invention, it is possible to produce oyster pockets which have a substantially parallelepipedal structure in use and whose lateral flanks once the folds have been deployed have a certain rigidity preventing the upper and lower main faces from being crushed against the 'other and therefore cause the flattening of the pocket.
Pour réaliser une poche ostréicole à partir d'un élément tubulaire tel que décrit, on entaille l'élément tubulaire au voisinage de ses extrémités, le long des arêtes longitudinales, sur une longueur correspondant sensiblement à la hauteur des zones latérales munies du ou des replis, on rabat vers l'intérieur les extrémités des zones latérales, puis on rabat les extrémités des faces supérieure et inférieure et enfin on lie les extrémités rabattues par des attaches ou analogues. To make an oyster pocket from a tubular element as described, the tubular element is notched in the vicinity of its ends, along the longitudinal edges, over a length substantially corresponding to the height of the lateral zones provided with the fold or folds , the ends of the lateral zones are folded inwards, then the ends of the upper and lower faces are folded back and finally the folded ends are linked by clips or the like.
Bien entendu, on peut envisager d'utiliser comme poche ostréicole l'élément tubulaire tel quel en prévoyant des moyens de fermeture d'extrémité appropriés. Of course, it is conceivable to use the tubular element as an oyster pocket as it is, by providing suitable end closure means.
Dans le but de mieux faire comprendre l'invention, on va maintenant décrire à titre d'exemple en aucune manière limitatif, un exemple de réalisation en se référant au dessin annexé dans lequel
- la figure 1 est une vue très schématique d'un élément tubulaire selon l'invention, et
- la figure 2 est une vue partielle de détail selon la flèche
A de la figure 1,
- la figure 3 est une vue analogue à la figure 2 d'une variante de réalisation.In order to better understand the invention, we will now describe by way of example in no way limiting, an exemplary embodiment with reference to the accompanying drawing in which
FIG. 1 is a very schematic view of a tubular element according to the invention, and
- Figure 2 is a partial detail view along the arrow
A of figure 1,
- Figure 3 is a view similar to Figure 2 of an alternative embodiment.
On voit sur la figure 1 un élément tubulaire en matière plastique, par exemple en polyéthylène haute densité, à structure réticulaire à mailles losanges formées par des filaments croisés. FIG. 1 shows a tubular element made of plastic, for example made of high density polyethylene, with a reticular structure with diamond meshes formed by crossed filaments.
Les mailles de l'élément selon l'invention présentent avantageusement des côtés de 4 à 23 mm et sont formées de filaments d'épaisseur comprise entre 1 et 4 mm. The meshes of the element according to the invention advantageously have sides from 4 to 23 mm and are formed of filaments with a thickness between 1 and 4 mm.
Dans deux zones diamétralement opposées 1 et 2, l'élément tubulaire présente des replis 3 de section sensiblement en forme de V dont la l'arête de sommet 4 est dirigée vers l'intérieur de l'élément. In two diametrically opposite zones 1 and 2, the tubular element has folds 3 of substantially V-shaped section, the top edge 4 of which is directed towards the interior of the element.
Chacune des zones latérales munie d'un repli 3 se raccorde à chacune des faces principales supérieure et inférieure de l'élément tubulaire par des arêtes longitudinales 5. Each of the lateral zones provided with a fold 3 is connected to each of the upper and lower main faces of the tubular element by longitudinal edges 5.
Une vue de détail de la structure de la figure 1, selon la flèche A est illustrée à la figure 2. A detailed view of the structure of FIG. 1, according to arrow A is illustrated in FIG. 2.
La figure 3 illustre une variante de réalisation dans laquelle, outre les mailles losanges, la structure comporte des filaments longitudinaux de renfort 6 dans et au voisinage des zones 1 et 2 comportant les replis 3. FIG. 3 illustrates an alternative embodiment in which, in addition to the diamond meshes, the structure comprises longitudinal reinforcing filaments 6 in and in the vicinity of zones 1 and 2 comprising the folds 3.
Comme on le voit sur cette figure, la disposition des filaments longitudinaux 6 est prévue pour permettre de former les arêtes 4 et 5 entre lesdits filaments longitudinaux par pliage de la structure après son obtention par extrusion. As can be seen in this figure, the arrangement of the longitudinal filaments 6 is provided to enable the edges 4 and 5 to be formed between said longitudinal filaments by folding the structure after it has been obtained by extrusion.
Bien que l'invention ait été décrite en liaison avec un mode particulier de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter de nombreuses variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit. Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be brought to many variations and modifications without departing from its scope or nor of his mind.
