Abstract

The device has metallic poles (1) that are constituted by a metallic part including a base vertical plated in a concrete (3). Metallic crossbeams (6) are bolted to a ground through a threaded rod (4) having a diameter of 25 millimeter. Wood plates are fixed to the poles. A fixation system is arranged between a safety screw thread (17) and a rigid barrier by a cable (14) having a diameter of 10 millimeter.

Description

La présente invention concerne une barrière rigide de protection de bord de piste de ski. Elle permet de préserver le manteau neigeux dans des secteurs sensibles, tout en corrigeant le dévers de la piste, elle facilite la manipulation 5 des filets de sécurité fixés à cette barrière, afin que ceux ci gardent une tension efficace et optimise la sécurité des skieurs. L'absence de cette barrière provoque généralement un espace vide entre la base des filets de sécurité et la piste, laissant un passage libre sous le filet de protection rendant ainsi inefficace le système de sécurité en cas de 10 chute d'un skieur. L'absence de cette barrière ne permet pas de stocker la neige qui, au fur à mesure est poussée vers l'extérieur de la piste par le passage des skieurs, et disparaît rapidement de la piste, provoquant sa fermeture prématurée. L'absence de la barrière ne permet pas aux pisteurs de régler 15 régulièrement la tension du filet. En cas de chute de neige, le système d'attache reste enfouit sous la neige, ce qui provoque une tension des attaches et du filet, le rendant rigide et fragile, annulant l'efficacité du filet de sécurité. L'absence de la barrière ne permet pas pour les pistes qui sont exposées sud ouest dans l'hémisphère nord de conserver le manteau neigeux qui fond 20 rapidement de par cette exposition. La barrière selon l'invention permet de remédier à ces inconvénients. Elle permet de garder le filet à la hauteur du manteau neigeux. La barrière permet de faciliter le travail des pisteurs par un montage et démontage rapides de la partie inférieure du filet au sol grâce à son système 25 de fixation placé sur le côté extérieur de la barrière, et permet un réglage optimal de la tension du filet de sécurité et préserve ainsi son bon fonctionnement. La barrière permet un stockage de neige permanent et le maintien d'une hauteur de neige constante pendant la saison, facilitant le travail effectué par 30 les engins de damage et ainsi de garder de bonnes conditions d'enneigement sur la piste. Les dessins annexés illustrent l'invention : La figure 1 représente en coupe, le dispositif de l'invention, La figure 2 représente de face interne, les éléments de l'invention, 35 La figure 3 représente de face interne, le dispositif de l'invention, La figure 4 représente de face externe, le dispositif de l'invention. En référence à ces dessins, le dispositif nommé barrière rigide de protection de piste est d'une hauteur utile moyenne de 800mm. Est constitué par une série de poteaux (1) métalliques en HEA 100, espacés d'une longueur égale à la longueur d'une traverse (2) en bois. The present invention relates to a rigid ski slope edge protection barrier. It makes it possible to preserve the snowpack in sensitive areas while correcting the slope of the runway, it facilitates the handling of the safety nets fixed to this barrier, so that they keep an effective tension and optimizes the safety of the skiers. The absence of this barrier generally causes an empty space between the base of the safety nets and the track, leaving a free passage under the protective net thus rendering the safety system ineffective in the event of a skier's fall. The absence of this barrier does not allow to store the snow which, as it is pushed to the outside of the track by the passage of skiers, and quickly disappears from the track, causing its premature closure. The absence of the barrier does not allow the trackers to regulate the net tension regularly. In case of snowfall, the fastening system remains buried under the snow, which causes a tension of the fasteners and the net, making it rigid and fragile, canceling the effectiveness of the safety net. The absence of the barrier makes it impossible for tracks that are exposed south-west in the northern hemisphere to keep the snowpack melting rapidly by this exposure. The barrier according to the invention overcomes these disadvantages. It keeps the net at the height of the snowpack. The barrier facilitates the work of the trackers by rapid assembly and disassembly of the lower part of the net on the ground by virtue of its fastening system placed on the outer side of the barrier, and allows an optimal adjustment of the tension of the thread. safety and thus preserves its smooth operation. The barrier allows for permanent snow storage and the maintenance of a constant snow depth during the season, facilitating the work done by the grooming machines and thus keeping good snow conditions on the track. The accompanying drawings illustrate the invention: FIG. 1 is a cross-section of the device of the invention, FIG. 2 shows an internal face of the elements of the invention, FIG. FIG. 4 represents an external face of the device of the invention. With reference to these drawings, the device called rigid barrier track protection has an average useful height of 800mm. Is constituted by a series of posts (1) metal HEA 100, spaced a length equal to the length of a cross (2) wood.

La fixation des poteaux (1) dans le sol est assurée par l'enfouissement de sa base, dans un volume de béton d'environ 50 litres servant de corps mort (3) et par un ancrage diamètre 25mm (4) d'une profondeur minimum de 1500mm, scellé au coulis de ciment et boulonné (5) sur un UPN 100 mm (6) soudé (7) au poteau et renforcé par une pièce métallique triangulaire (8) d'une épaisseur de 10mm et environ 100mm de côté, et formant la traverse inférieure (6). Les deux poteaux (9) d'extrémités sont constitués par un UPN 100mm (10) et de deux traverses inférieures en UPN 100mm (6) soudées sur le poteau et renforcées par les pièces métalliques (8).Ces traverses sont fixées au sol par deux ancrages (4). Entre les poteaux (1) où (9), viennent se glisser les plateaux bois (2) bloqués à la base par deux butées (11) en fer rond diamètre 10mm. Les plateaux bois (2) sont d'une épaisseur d'environ 75mm, largeur 15 225mm et d'une longueur maximum de 4500mm. Les plateaux bois sont fixés aux poteaux par des vis diamètre 6 mm (12). La partie supérieure de la barrière est protégée par une cornière métallique (13) 100x100 mm épaisseur 10 mm, qui servira de protection pour 20 les plateaux bois (2) contre un contact éventuel de la lame de la dameuse. La fixation du filet (17) à la barrière se fera par l'intermédiaire d'un câble (14) de diamètre 10mm tressé dans la base du filet, et passant dans des anneaux à ouverture rapide du type queue de cochon ou mousquetons (15) vissés sur les plateaux en bois du côté extérieur de la piste espacés d'environ 2500mm. La mise en tension du câble est réalisée à l'aide d'un treuil manuel (16) du type treuil de halage. The fixing of the posts (1) in the ground is ensured by the burial of its base, in a volume of concrete of about 50 liters serving as dead body (3) and by an anchoring diameter 25mm (4) of a depth minimum of 1500mm, cement grouted and bolted (5) on a UPN 100mm (6) welded (7) to the post and reinforced by a triangular metal piece (8) with a thickness of 10mm and about 100mm on the side, and forming the bottom rail (6). The two end posts (9) are constituted by a UPN 100mm (10) and two lower UPN 100mm crosspieces (6) welded to the post and reinforced by the metal pieces (8) .These sleepers are fixed to the ground by two anchors (4). Between the posts (1) where (9), come to slide the wooden trays (2) blocked at the base by two abutments (11) round iron diameter 10mm. The wood trays (2) are of a thickness of about 75mm, width 225mm and a maximum length of 4500mm. The wooden trays are fixed to the posts by 6 mm diameter screws (12). The upper part of the barrier is protected by a metal bracket (13) 100x100 mm thickness 10 mm, which will serve as protection for the wooden trays (2) against possible contact with the blade of the groomer. The fastening of the net (17) to the barrier will be done by means of a cable (14) of diameter 10 mm braided in the base of the net, and passing in fast-opening rings of the pigtail type or carabiners (15). ) screwed onto wooden trays on the outside of the track spaced approximately 2500mm apart. The cable is tensioned using a manual winch (16) of the towing winch type.
