Dans le domaine des sports de glisse pratiqués dans une station de sport d'hiver, il est courant d'utiliser des piquets pour baliser une aire de jeu, telle qu'une piste de ski ou analogue. Un tel piquet est notamment destiné à supporter un filet de balisage et/ou de signalisation de l'aire de jeu.In the field of sliding sports practiced in a winter sports resort, it is common to use stakes to mark a playground, such as a ski slope or the like. Such a post is particularly intended to support a markup net and / or signaling of the playing area.
Le piquet est constitué d'une tige cylindrique de révolution qui est enfoncée dans la neige et/ou dans le sol par l'intermédiaire d'une extrémité inférieure qui comporte une pointe. La tige cylindrique comporte également une extrémité supérieure pourvue d'une tête à frapper sur laquelle un utilisateur peut asséner des coups dans le but d'enfoncer l'extrémité inférieure dans la neige et/ou le sol. La tige cylindrique est par exemple pourvue d'un ou plusieurs anneaux ou crochets destinés à recevoir une maille respective du filet de protection.The post consists of a cylindrical rod of revolution which is driven into the snow and / or into the ground via a lower end which has a tip.

Description des figures.Description of the figures.
La présente invention sera mieux comprise à la lecture de la description qui va en être faite d'un exemple de réalisation, en relation avec la figure unique de la planche annexée, dans laquelle la figure unique illustre un piquet selon la présente invention.The present invention will be better understood on reading the description which will be made of an exemplary embodiment, in connection with the single figure of the accompanying plate, wherein the single figure illustrates a peg according to the present invention.
Dans une station de sport d'hiver, il est courant de délimiter une aire de jeu, telle qu'une piste de ski ou analogue, à l'aide de piquets 1 destinés à supporter un filet. Un tel piquet 1 est souhaité rigide, imputrescible et pérenne pour pouvoir résister à des efforts conséquents, notamment ceux susceptibles d'être générés par un impact d'un skieur échouant dans le filet, par le poids de la neige s'accumulant sur le piquet et/ou le filet, et/ou par la force du vent s'engouffrant dans le filet.In a winter sports resort, it is common to define a playground, such as a ski slope or the like, with stakes 1 for supporting a net. Such a peg 1 is desired rigid, rotproof and durable to withstand significant efforts, including those likely to be generated by an impact of a skier failing in the net, by the weight of the snow accumulating on the stake and / or the net, and / or by the force of the wind engulfing the net.
Le piquet 1 comprend une tige 2, préférentiellement cylindrique, qui s'étend selon un axe général d'extension A entre une extrémité supérieure 3 et une extrémité inférieure 4 que comporte la tige 2. Dans le cas courant où la tige 2 est cylindrique, l'extrémité supérieure 3 présente un diamètre Ds de l'ordre de 15 mm, à plus ou moins 5% près. L'extrémité supérieure 3 présente aussi une longueur Ls de l'ordre de 36 mm, à plus ou moins 5% près. L'extrémité inférieure 4 quant à elle présente une longueur Lj qui est de l'ordre de 45 mm, à plus ou moins 5% près. L'extrémité inférieure 4 est notamment agencée en biseau pour faciliter sa pénétration dans la neige et/ou dans le sol.The peg 1 comprises a rod 2, preferably cylindrical, which extends along a general axis of extension A between an upper end 3 and a lower end 4 that comprises the rod 2. In the current case where the rod 2 is cylindrical, the upper end 3 has a diameter Ds of the order of 15 mm, plus or minus 5%. The upper end 3 also has a length Ls of the order of 36 mm, within plus or minus 5%. The lower end 4 has a length Lj which is of the order of 45 mm, within plus or minus 5%. The lower end 4 is arranged in particular bevel to facilitate its penetration into the snow and / or soil.
Il est proposé par la présente invention que la tige 2 soit constituée d'un noyau 5 réalisé en une première matière et d'une gaine 6 réalisée en une deuxième matière qui enveloppe le noyau 5. Le noyau 5, également de préférence cylindrique, présente un diamètre Di constant qui est de l'ordre de 12 mm, à plus ou moins 5% près. Le noyau 5 est indifféremment plein ou creux. La gaine 6 quant à elle présente une épaisseur E qui varie de 3 mm, à plus ou moins 5% près, au niveau de l'extrémité supérieure' 3, jusqu'à 6 mm, à plus ou moins 5% près, au niveau de l'extrémité inférieure 4 et au niveau d'une zone médiane 7 comprise entre les deux extrémités 3,4 du piquet 1. Le passage d'une épaisseur E de la gaine 6 de 3 mm à 6 mm se fait sur une longueur L qui est de l'ordre de 10 mm, à plus ou moins 5% près.It is proposed by the present invention that the rod 2 consists of a core 5 made of a first material and a sheath 6 made of a second material which surrounds the core 5. The core 5, also preferably cylindrical, presents a constant diameter Di which is of the order of 12 mm, within plus or minus 5%. The core 5 is indifferently full or hollow. The sheath 6 has a thickness E which varies from 3 mm, within plus or minus 5%, at the upper end '3, up to 6 mm, within plus or minus 5%, at the of the lower end 4 and at a median zone 7 between the two ends 3,4 of the post 1. The passage of a thickness E of the sheath 6 from 3 mm to 6 mm is a length L which is of the order of 10 mm, within plus or minus 5%.
Le premier matériau est par exemple constitué d'une résine polyester chargée en fibres de verre 8. Les fibres de verre 8 sont orientées parallèlement à l'axe général d'extension A du piquet 1. Ces dispositions visent à conforter la rigidité du piquet 1.The first material consists for example of a polyester resin filled with glass fibers 8. The glass fibers 8 are oriented parallel to the general axis of extension A of the post 1. These provisions are intended to reinforce the rigidity of the stake 1 .
Le deuxième matériau est par exemple constitué d'un matériau thermoplastique qui est rapporté par injection autour du noyau 5.The second material is for example made of a thermoplastic material which is reported by injection around the core 5.
En sus de la tige 2, le piquet 1 comporte une tête à frapper 9 qui est rapportée par emboîtement, par collage, par soudage ou analogue, sur l'extrémité supérieure 3 de la tige 2. La tête à frapper 9 comprend un manchon 10 qui reçoit l'extrémité supérieure 3 de la tige 2. La tête à frapper 9 comprend aussi une zone terminale 11 globalement agencée en une enclume qui est destinée à recevoir des coups assénés par un utilisateur pour enfoncer le piquet 1 dans la neige et/ou le sol. La tête à frapper 9 est pourvue d'un crochet 12 pour la réception d'une maille du filet. Le crochet 12 est avantageusement équipé d'une languette 13 qui prend appui contre la zone terminale 11 de la tête à frapper 9 pour constituer un organe d'interdiction d'une échappée de la maille du filet hors du crochet 12.In addition to the rod 2, the stake 1 comprises a striking head 9 which is attached by interlocking, gluing, welding or the like on the upper end 3 of the rod 2. The striking head 9 comprises a sleeve 10 which receives the upper end 3 of the rod 2. The striking head 9 also comprises an end zone 11 generally arranged in an anvil which is intended to receive blows driven by a user to drive post 1 into the snow and / or the ground. The striking head 9 is provided with a hook 12 for receiving a mesh of the net. The hook 12 is advantageously equipped with a tongue 13 which bears against the end zone 11 of the striking head 9 to constitute a member for preventing a breakaway of the mesh of the net from the hook 12.
Le piquet 1 comporte enfin une pointe 14 rapportée par emboîtement, par collage, par soudage ou analogue, sur l'extrémité inférieure 4 du piquet 1.The stake 1 has finally a tip 14 reported by interlocking, gluing, welding or the like, on the lower end 4 of the stake 1.
La pointe et la tête à frapper 9 sont par exemple réalisée en un matériau métallique, aluminium notamment, ou en matériau thermoplastique.The tip and the knocking head 9 are for example made of a metallic material, aluminum in particular, or of thermoplastic material.
La tête à frapper 9 peut présenter d'autres formes que celle représentée. The striking head 9 may have other forms than the one shown.
