Abstract
Description
On utilise couramment pour la protection contre les cervidés de plants, tels que des jeunes arbres, pendant leurs premières années de croissance, des dispositifs de protection constitués par un élément tubulaire formé d'un matériau à structure réticulaire, notamment en matière plastique, disposé à distance autour dudit plant à protéger et maintenu en place à l'aide de piquets plantés dans le sol. Is commonly used for protection against cervids of plants, such as young trees, during their first years of growth, protective devices constituted by a tubular element formed of a material with a reticular structure, in particular plastic, arranged to distance around said plant to be protected and kept in place using stakes planted in the ground.
La hauteur de ltélément tubulaire ainsi que la forme et les dimensions des mailles de la structure sont choisies en fonction de l'utilisation envisagée. The height of the tubular element as well as the shape and dimensions of the meshes of the structure are chosen according to the intended use.
Les éléments tubulaires en matériau à structure réticulaire sont en général réunis aux piquets par des moyens de fixation tels que des agrafes, des liens ou des attaches rapides. The tubular elements made of material with a reticular structure are generally joined to the stakes by fastening means such as staples, ties or quick fasteners.
Du fait de la nécessité de planter des piquets et d'utiliser des moyens de fixation aux piquets, la mise en place des dispositifs est relativement longue et complexe. Because of the need to plant stakes and to use means for fixing to the stakes, the installation of the devices is relatively long and complex.
La présente invention se propose de fournir un dispositif de protection arbres, apte à être mis en place autour d'un plant de jeune arbre, dès la plantation, sans nécessiter de piquets pour son maintien dans le sol. The present invention proposes to provide a tree protection device, capable of being placed around a young tree plant, from planting, without requiring stakes to keep it in the ground.
Le dispositif selon l'invention se caractérise essentiellement par le fait outil est constitué d'une gaine tubulaire fermée en matériau à structure réticulaire, notamment en matiere plastique, à mailles extensibles, ladite gaine tubulaire étant mise en place autour du tronc d'un plants sans piquets de fixation dans le sol et étant déformable en sens radial jusqu à atteindre, sans rupture, un diamètre au moins égal à trois fois son diamètre initial. The device according to the invention is essentially characterized by the tool fact consists of a closed tubular sheath made of material with a reticular structure, in particular plastic, with extensible meshes, said tubular sheath being placed around the trunk of a plant. without fixing stakes in the ground and being deformable in the radial direction until reaching, without breaking, a diameter at least equal to three times its initial diameter.
On comprend que le dispositif selon l'invention, du fait des propriétés d'extensibilité en sens radial de la gaine, peut être mis en place autour du tronc d'un plant de jeune arbre, tel que par exemple un peuplier, et demeurer en place autour du tronc au cours de la croissance de l'arbre en augmentant de diamètre au fur et à mesure de l'augmentation du diamètre de l'arbre, le dispositif restant en permanence au contact du tronc. It is understood that the device according to the invention, due to the properties of extensibility in the radial direction of the sheath, can be placed around the trunk of a young tree plant, such as for example a poplar, and remain in place around the trunk during the growth of the tree by increasing in diameter as the diameter of the tree increases, the device remaining permanently in contact with the trunk.
Le dispositif selon l'invention assure ainsi une protection efficace du plant, notamment contre l'abroutissement et le frottis des cervidés. De plus, le dispositif selon l'invention confère au plant une protection contre le vent du fait qu au moment de la mise en place et pendant une certaine période au début de la croissance du plant les ouvertures des mailles de la gaine tubulaire en sens latéral sont faibles. The device according to the invention thus provides effective protection of the plant, in particular against browsing and smears of deer. In addition, the device according to the invention gives the plant protection against the wind because at the time of the establishment and for a certain period at the start of the growth of the plant, the openings of the meshes of the tubular sheath in the lateral direction are weak.
Une telle gaine assure également un certain effet de serre qui favorise la pousse du plant. Such a sheath also provides a certain greenhouse effect which promotes plant growth.
Le dispositif selon l'invention peut par exemple être réalisé en polyéthylène à mailles de forme losange. The device according to the invention can for example be made of polyethylene with diamond-shaped meshes.
De telles structures réticulaires en matière plastique à mailles de forme losange peuvent être réalisées par extrusion en mettant en oeuvre le procédé connu sous le nom de Netlon et décrit par exemple dans le brevet britannique 836 555. Such reticular structures made of plastic with diamond-shaped meshes can be produced by extrusion using the method known under the name of Netlon and described for example in British patent 836 555.
Dans le but de mieux faire comprendre l'invention on va maintenant en décrire un exemple de réalisation à titre nullement limitatif en se référant au dessin annexé dans lequel
- la figure I illustre schématiquement un dispositif selon l'invention mis en place autour du tronc d'un plant d'arbre,
- la figure 2 illustre le dispositif selon l'invention en place au cours de la croissance de l'arbre, et
- la figure 3 est une vue de détail de la structure du dispositif selon l'invention.In order to better understand the invention we will now describe an exemplary embodiment thereof in no way limiting, with reference to the accompanying drawing in which
FIG. I diagrammatically illustrates a device according to the invention placed around the trunk of a tree plant,
FIG. 2 illustrates the device according to the invention in place during the growth of the tree, and
- Figure 3 is a detail view of the structure of the device according to the invention.
Le dispositif selon l'invention, désigné globalement par 1, est constitué d'une gaine tubulaire fermée à structure réticulaire à mailles extensibles latéralement de manière à permettre une déformation en sens radial de la gaine. On voit sur la figure 3 un détail d'une structure selon l'invention réalisée en matière plastique, notamment en polyéthylène, à mailles de forme losange. The device according to the invention, generally designated by 1, consists of a closed tubular sheath with a reticular structure with laterally expandable meshes so as to allow deformation in the radial direction of the sheath. FIG. 3 shows a detail of a structure according to the invention made of plastic, in particular polyethylene, with diamond-shaped meshes.
Comme on le comprend à l'examen des figures 1 et 2, la gaine constituant le dispositif selon l'invention est mise en place autour du tronc d'un plant de jeune arbre lors de la plantation et demeure sur celui-ci au cours de la croissance de l'arbre. As can be understood on examining FIGS. 1 and 2, the sheath constituting the device according to the invention is placed around the trunk of a young tree plant during planting and remains thereon during tree growth.
Du fait des propriétés d'extensibilité en sens radial des mailles de la gaine, le dispositif reste maintenu au contact du tronc pendant la croissance en augmentant le diamètre de manière correspondante. Due to the properties of extensibility in the radial direction of the meshes of the sheath, the device remains maintained in contact with the trunk during growth by increasing the diameter correspondingly.
Afin que, dès la plantation, la gaine soit maintenue par sa propre élasticité au contact du tronc, il suffit de choisir un diamètre de gaine inférieur au diamètre du tronc du plant correspondant. So that, from planting, the sheath is maintained by its own elasticity in contact with the trunk, it suffices to choose a sheath diameter smaller than the diameter of the trunk of the corresponding plant.
La hauteur de la gaine illustrée sur le dessin n'est bien entendu pas limitative. En particulier la gaine peut présenter une hauteur plus grande que celle illustrée. The height of the sheath illustrated in the drawing is of course not limiting. In particular, the sheath may have a greater height than that illustrated.
Dans le mode de réalisation illustré le dispositif est constitué d'une gaine fermée enfilée sur le tronc du plant. En variante on peut utiliser un tronçon de nappe à structure réticulaire présentant les mêmes propriétés d'extension des mailles mis en place autour du plant et assemblé par agrafage des filaments de lisière. Cette variante permet de mettre en oeuvre l'invention avec des arbres déjà plantés. In the illustrated embodiment, the device consists of a closed sheath threaded on the trunk of the plant. As a variant, it is possible to use a section of web with a reticular structure having the same properties of extension of the meshes placed around the plant and assembled by stapling the selvedge filaments. This variant makes it possible to implement the invention with trees already planted.
Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter différentes 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 made different variants and modifications without departing from its scope or of his mind.
