Description

Domaine de l'inventionField of the invention

L'invention se rapporte à un élément de piste artificielle de glisse et à une piste artificielle de glisse, telles que piste de ski.The invention relates to an artificial gliding track element and to an artificial gliding track, such as a ski slope.

Elle concerne en particulier un élément de piste de glisse qui, utilisé en plusieurs exemplaires, permet de constituer une piste de glisse.It relates in particular to a gliding track element which, used in several copies, makes it possible to constitute a gliding track.

Etat de la techniqueState of the art

Les pistes artificielles de glisse sont connues et utilisées depuis longtemps. On les utilise communément comme substitut à des pistes de ski dans des régions sans neige ou insuffisamment enneigées ou à des époques de l'année où il n'existe pas de neige persistante. Les pistes artificielles de glisse trouvent également une application pour l'apprentissage du ski en salle ou sur des terrains spécialement aménagés mais sans neige.The artificial slopes of gliding are known and used for a long time. They are commonly used as a substitute for ski trails in areas with no snow or snow, or at times of the year when there is no persistent snow. The artificial slopes of sliding also find an application for the learning of the ski in room or on specially arranged grounds but without snow.

Des pistes artificielles de ski connues comprennent habituellement un support portant des fils transversaux dont la rigidité est suffisante pour supporter un skieur. Divers agencements ont été proposés à cet effet, mais aucun d'eux ne donne entière satisfaction.Known artificial ski slopes usually comprise a support carrying transverse threads whose rigidity is sufficient to support a skier. Various arrangements have been proposed for this purpose, but none of them gives complete satisfaction.

Dans le document US-3 574 107 , on décrit une piste artificielle de ski, formée d'une structure multicouche dont la face supérieure porte des fils rigides en polymère de synthèse. Dans cette piste artificielle de ski connue, les fils rigides sont constitués de tiges filiformes individuelles, dont une ou les deux extrémités sont noyées individuellement dans la couche supérieure du multicouche. Par leur conception, ces tiges filiformes présentent généralement une rigidité inadaptée à une bonne glisse, ce qui constitue un désavantage. En outre, il est pratiquement impossible de les remplacer en cas de bris ou d'usure. L'entretien de la piste est dès lors particulièrement difficile et onéreux. Un autre désavantage de la piste artificielle de ski proposée dans le document US-3 574 107 réside dans la structure multicouche. Celle-ci forme en effet une nappe de grande dimension sur le sol, ce lui confère l'inconvénient de s'adapter difficilement à des terrains dont la topographie est irrégulière. La structure multicouche forme en outre une surface résistante et dure. Elle est par conséquent mal adaptée à amortir les chocs, en cas de chute d'un skieur, ce qui constitue un désavantage supplémentaire de cette piste artificielle connue.In the document US-3,574,107 , there is described an artificial ski track, formed of a multilayer structure whose upper face carries rigid son synthetic polymer. In this known artificial ski slope, the rigid yarns consist of individual filiform rods, one or both ends of which are embedded individually in the upper layer of the multilayer. By their design, these filiform stems generally have a rigidity unsuitable for a good glide, which is a disadvantage. In addition, it is virtually impossible to replace them in case of breakage or wear. The maintenance of the track is therefore particularly difficult and expensive. Another disadvantage of the artificial ski slope proposed in the document US-3,574,107 lies in the multilayer structure. This forms a large sheet on the ground, which gives it the disadvantage of being difficult to adapt to terrain whose topography is irregular. The multilayer structure also forms a strong and hard surface. It is therefore poorly adapted to dampen shocks in the event of a skier's fall, which constitutes an additional disadvantage of this known artificial track.

Dans le document GB-1418458 , on décrit une piste artificielle de ski, constituée par l'assemblage de panneaux triangulaires, portant des fils rigides transversaux. Les panneaux sont formés de trois longerons laissant un vide entre-eux et les fils sont des tiges filiformes individuelles, formant partie intégrante des longerons du panneau. Cette piste de ski connue présente les inconvénients énoncés plus haut, concernant les tiges filiformes. Celles-ci sont mal adaptées à une bonne glisse et leur remplacement, en cas de bris ou d'usure excessive, est pratiquement impossible ou requiert un travail long et onéreux.In the document GB-1418458 , an artificial ski slope consisting of the assembly of triangular panels bearing transverse rigid wires is described. The panels are formed of three longitudinal members leaving a void between them and the son are individual filiform rods forming integral part of the rails of the panel. This known ski slope has the drawbacks mentioned above, concerning threadlike rods. These are poorly adapted to good sliding and their replacement, in case of breakage or excessive wear, is virtually impossible or requires a long and expensive work.

JP-A-04080408 décrit un élément de piste artificielle de glisse comprenant des fils fixés à un panneau à claire-voie, les fils étant assemblés en touffes. JP-A-04080408 discloses an artificial gliding track element comprising threads attached to a slatted panel, the threads being assembled into tufts.

Résumé de l'inventionSummary of the invention

L'invention remédie aux inconvénients des pistes artificielles de ski connues, décrites plus haut, en fournissant une piste artificielle de glisse de conception nouvelle, qui s'adapte facilement à la topographie du lieu d'implantation, remplit les conditions nécessaires pour une glisse de bonne qualité et sûre (en réalisant notamment un bon amortissement des chocs en cas de chute) et permet, en cas de besoin, un remplacement facile, rapide et économique des fils usagées de la piste.The invention overcomes the drawbacks of the known artificial ski slopes, described above, by providing an artificial gliding track of new design, which easily adapts to the topography of the place of implantation, fulfills the conditions necessary for a good quality and safe gliding (in particular achieving a good shock absorption in the event of a fall) and allows, if necessary, an easy, fast and economical replacement of used track wires.

A cet effet, l'invention concerne un élément de piste artificielle de glisse, selon la revendication 1.For this purpose, the invention relates to an artificial gliding track element, according to claim 1.

Le panneau est posé sur un tapis en une matière solide élastique (par exemple un élastomère ou une mousse en polymère de synthèse), ledit tapis présentant des bourrelets superficiels qui sont séparés par un réseau de cannelures et qui sont insérés dans les vides du panneau.The panel is laid on a mat of resilient solid material (e.g. an elastomer or synthetic polymer foam), said mat having surface beads which are separated by a network of flutes and which are inserted into the voids of the panel.

Une partie au moins des vides du panneau sont comblés, au moins partiellement, par un corps élastique. Le corps élastique a pour fonction d'amortir les chocs au cas où un utilisateur de la piste de glisse viendrait à chuter. Chaque vide peut comprendre un tel corps élastique ; en variante, seuls un nombre limité de vides (par exemple deux vides sur trois) contiennent un tel corps élastique. Le corps élastique peut occuper la totalité de la superficie du vide où il se trouve ou seulement une partie de celle-ci. Dans le cas où le corps élastique occupe seulement une partie du vide, ladite partie peut être par exemple de 25 à 95 % de la superficie du vide, idéalement de 60 à 85 % de ladite superficie. Les dimensions du corps élastique doivent être adaptées pour que sa partie supérieure soit au-dessous de l'extrémité supérieure des touffes de fils, lorsque le panneau est utilisé sur le sol pour former une piste de glisse. En général, le corps élastique affleure sensiblement la face supérieure du panneau. La matière dont est constituée le corps élastique n'est pas critique pour la définition de l'invention. Des exemples de corps élastiques utilisables dans le cadre de l'invention comprennent des corps en une matière élastomère, des mousses en polymère de synthèse ou des enveloppes souples remplies d'un gaz sous pression.At least a portion of the voids of the panel are filled, at least partially, by an elastic body. The elastic body has the function of damping shocks in case a user of the gliding track would fall. Each void may include such an elastic body; alternatively, only a limited number of voids (for example two voids out of three) contain such an elastic body. The elastic body can occupy the entire area of the void where it is located or only a part of it. In the case where the elastic body occupies only a portion of the void, said portion may be for example 25 to 95% of the void area, ideally 60 to 85% of said area. The dimensions of the elastic body must be adapted so that its upper part is below the upper end of the tufts of threads, when the panel is used on the ground to form a sliding track. In general, the elastic body is substantially flush with the upper face of the panel. The material of which the elastic body is made is not critical for the definition of the invention. Examples of elastic bodies that may be used in the context of the invention include bodies made of an elastomeric material, synthetic polymer foams or flexible envelopes filled with a gas under pressure.

L'élément de piste de glisse selon l'invention est destiné à être produit en plusieurs exemplaires dans le but de les assembler pour former alors une piste artificielle de glisse, par exemple une piste artificielle de ski.The gliding track element according to the invention is intended to be produced in several copies for the purpose of assembling them to form then an artificial gliding track, for example an artificial ski track.

On entend par piste artificielle de glisse, une piste qui est réalisée en une matière ou un mélange de matières artificielles et qui possède, de par sa conception, des propriétés permettant à des engins spécialement adaptés d'y évoluer par glissement(tels que des traîneaux, des skis ou des raquettes de neige, par exemple). Dans le présent mémoire, une matière artificielle est, par définition, une matière qui n'existe pas naturellement, par opposition à la glace et à la neige, notamment.By artificial gliding track, is meant a track which is made of a material or a mixture of artificial materials and which, by its design, possesses properties allowing specially adapted apparatus to evolve by sliding (such as sleds). skis or snowshoes, for example). In this specification, an artificial material is, by definition, a naturally occurring material, as opposed to ice and snow, in particular.

L'élément selon l'invention comprend un panneau à claire-voie. La forme et les dimensions du panneau ne sont pas critiques pour la définition de l'invention. Le panneau a toutefois de préférence une forme sélectionnée parmi le triangle, le carré, le rectangle et l'hexagone. Le carré et le rectangle sont tout spécialement préférés.The element according to the invention comprises a slatted panel. The shape and dimensions of the panel are not critical for the definition of the invention. The panel, however, preferably has a shape selected from the triangle, the square, the rectangle and the hexagon. The square and the rectangle are especially preferred.

Les vides du panneau ont de multiples fonctions. En combinaison avec les fils (dont la constitution nouvelle et originale sera explicitée plus loin), les vides du panneaux participent à optimiser les propriétés glissantes de la piste de glisse. Une fonction supplémentaire des vides du panneau consiste à réduire la masse du panneau pour faciliter sa manutention et son stockage. Une autre fonction intéressante des vides du panneau consiste à permettre un écoulement naturel d'eau autour et sous la piste de glisse, sans nuire à ses capacités de glisse, ni perturber les utilisateurs de la piste. L'origine de cette eau est multiple et comprend notamment les eaux de précipitation (pluie, neige fondue), les eaux de ruissellement et l'eau utilisée pour l'entretien et le nettoyage de la piste artificielle de glisse. Nonobstant ce qui précède, la forme et les dimensions des vides du panneau ne sont pas critiques pour la définition de l'invention. La forme des vides peut être indifféremment circulaire, elliptique ou polygonale. Les formes polygonales sont préférées et, parmi celles-ci, les formes carrées et rectangulaires ont la préférence. Le nombre de vides par unité de surface du panneau (ou la superficie ou les dimensions des vides) doit être adapté pour ne pas nuire à la solidité et à la rigidité du panneau. Il va notamment dépendre de l'épaisseur du panneau et de la matière dont il est constitué. En pratique, le nombre de vides par unité d'aire du panneau, leur forme et leurs dimensions doivent être déterminés dans chaque cas particulier par l'homme du métier, au moyen d'un travail de recherche de routine.Panel voids have multiple functions. In combination with the threads (whose new and original constitution will be explained later), the panel voids help to optimize the sliding properties of the gliding track. An additional function of panel voids is to reduce panel weight for ease of handling and storage. Another interesting function of the voids of the panel is to allow a natural flow of water around and under the gliding track, without impairing its gliding ability, nor disturb the users of the track. The origin of this water is multiple and includes precipitation water (rain, slush), runoff water and water used for the maintenance and cleaning of the artificial gliding track. Notwithstanding the above, the shape and dimensions of the voids of the panel are not critical for the definition of the invention. The shape of the voids can be indifferently circular, elliptical or polygonal. Polygonal shapes are preferred and of these, square and rectangular shapes are preferred. The number of voids per unit area of the panel (or the area or dimensions of the voids) must be adapted to not impair the strength and rigidity of the panel. It will depend in particular on the thickness of the panel and the material of which it is constituted. In practice, the number of voids per unit area of the panel, their shape and their dimensions must be determined in each particular case by those skilled in the art, by means of routine research work.

Le panneau peut être réalisé par assemblage de longerons longitudinaux et transversaux. On préfère, selon une forme de réalisation particulière de l'invention, que le panneau soit monolithique. Les panneaux en résine de synthèse (avantageusement obtenus par une technique de moulage) sont spécialement recommandés. Pour la résine de synthèse, on recommande les polymères et copolymères dérivés d'oléfines, telles que l'éthylène, le propylène, et le butène. Les polyoléfines linéaires à basse densité conviennent bien et, parmi celles-ci, les polyéthylènes linéaires à basse densité (LDPE) sont préférés.The panel can be made by assembling longitudinal and transverse longitudinal members. According to a particular embodiment of the invention, it is preferred that the panel be monolithic. Synthetic resin panels (advantageously obtained by a molding technique) are especially recommended. For the synthetic resin, polymers and copolymers derived from olefins, such as ethylene, propylene, and butene, are recommended. Linear low density polyolefins are well suited, and of these, linear low density polyethylenes (LDPE) are preferred.

Les fils servent à former la surface de glisse de la piste, en supportant les utilisateurs au-dessus du panneau. Selon l'invention, les fils sont assemblées en touffes (ou bouquets) de fils, le panneau est percé de trous borgnes et les touffes de fils sont enchâssées dans ces trous borgnes. Par définition, une touffe de fils est un assemblage de fils en faisceaux ou bouquet (à la manière d'une brosse), dans lequel chaque fil conserve son individualité, par opposition aux mèches de fils torsadés ou tressés.
Toutes autres choses égales, les propriétés de la surface de glisse (spécialement son pouvoir glissant, défini par son coefficient global de frottement) vont être conditionnées par les dimensions des fils, par leur constitution, leurs propriétés mécaniques (notamment leur résistance à la flexion et au flambage) et par le nombre de fils dans chaque touffe de fils. En pratique, les fils pourront être d'autant plus longs et d'autant plus minces (et par conséquent d'autant plus souples) que le nombre de fils par touffe est important et que la résistance des fils au flambage est élevée. Il revient à l'homme du métier de déterminer dans chaque cas particulier le nombre optimum de fils individuels dans chaque touffe, en fonction des conditions d'utilisation et des paramètres à sa disposition. En général, on obtient de bons résultats avec des touffes comprenant plus de 5 fils et moins de 100 fils individuels, les touffes de 10 à 60 fils convenant bien dans la plupart des cas, celles contenant de 15 à 50 fils individuels étant spécialement recommandées.
Les dimensions optimum des fils, leur nombre dans chaque touffe et le nombre de touffes par unité d'aire du panneau va dépendre de divers paramètres, notamment de la pente de la piste de glisse, des engins destinés à circuler sur la piste de glisse, de la matière des fils, de leur constitution et du coefficient global de frottement de la piste. Il revient à l'homme du métier de les déterminer dans chaque cas particulier par un travail de recherche de routine. De manière générale, des fils qui conviennent dans la majorité des cas sont des fils cylindriques dont le diamètre se situe entre 0,1 et 1,50 µm (de préférence de 0,2 à 1,00 µm) et dont la longueur au-dessus du panneau est sensiblement comprise entre 5 et 80 mm (de préférence de 10 à 50 mm). Les fils peuvent être en toute matière naturelle ou artificielle adéquate. On préfère des fils en résine de synthèse. Les polyamides et les polyesters constituent deux classes de matières préférées pour les fils. Les téréphtalates de polyoléfines sont préférés, parmi lesquels le téréphtalate de polybutène convient généralement bien.
La section transversale des fils n'est pas critique et peut par exemple être celle d'un cercle, d'une ellipse ou d'un polygone (par exemple un triangle, un carré, un hexagone ou un octogone). Chaque fil peut être une fibre monolithique individuelle ou une mèche de fibres, dans laquelle les fibres peuvent souvent être torsadées ou tressées. Les fibres monolithiques et celles qui sont assemblées en mèche peuvent être des fibres pleine ou des fibres creuses, tubulaires. On préfère que les fils soient des fibres monolithiques et, parmi celles-ci, les fibres pleines ont la préférence.The wires are used to form the sliding surface of the track, supporting the users above the panel. According to the invention, the son are assembled in tufts (or bunches) of son, the panel is pierced with blind holes and tufts of son are embedded in these blind holes. By definition, a tuft of threads is an assembly of bundled or bunched yarns (in the manner of a brush) in which each yarn retains its individuality, as opposed to strands of twisted or braided yarns.
All other things being equal, the properties of the sliding surface (especially its sliding power, defined by its overall coefficient of friction) will be conditioned by the dimensions of the wires, by their constitution, their mechanical properties (in particular their resistance to bending and buckling) and by the number of threads in each tuft of threads. In practice, the son may be even longer and even thinner (and therefore all the more flexible) as the number of son per tuft is important and the resistance son buckling is high. It's up to the man from to determine in each particular case the optimum number of individual son in each tuft, according to the conditions of use and the parameters at its disposal. In general, good results are obtained with tufts comprising more than 5 yarns and less than 100 individual yarns, the tufts of 10 to 60 yarns being suitable in most cases, those containing from 15 to 50 individual yarns being especially recommended.
The optimum dimensions of the wires, their number in each tuft and the number of tufts per unit area of the panel will depend on various parameters, including the slope of the gliding track, machines intended to travel on the gliding track, the material of the yarns, their constitution and the overall coefficient of friction of the track. It is up to the person skilled in the art to determine them in each particular case by routine research work. In general, yarns which are suitable in the majority of cases are cylindrical yarns whose diameter is between 0.1 and 1.50 μm (preferably 0.2 to 1.00 μm) and the length of which is the top of the panel is substantially between 5 and 80 mm (preferably 10 to 50 mm). The son can be in any natural or artificial material adequate. Synthetic resin wires are preferred. Polyamides and polyesters are two classes of preferred materials for yarns. Polyolefin terephthalates are preferred, of which polybutene terephthalate is generally well suited.
The cross section of the threads is not critical and may for example be that of a circle, an ellipse or a polygon (for example a triangle, a square, a hexagon or octagon). Each yarn may be an individual monolithic fiber or a fiber tow, in which the fibers may often be twisted or braided. The monolithic fibers and those which are assembled in wicks may be solid fibers or hollow, tubular fibers. It is preferred that the yarns be monolithic fibers and of these, the solid fibers are preferred.

La fixation des fils dans les trous borgnes peut être obtenue par tout moyen connu adéquat.Fixing the son in the blind holes can be obtained by any suitable known means.

Dans une forme de réalisation avantageuse de l'invention, la fixation des touffes de fils dans les trous borgne est réalisée au moyen d'agrafes, qui sont fichées dans la paroi des trous borgnes. Dans une mode d'exécution préféré de cette forme de réalisation de l'invention, les touffes de fils sont pliées et chevauchées par les agrafes, celles-ci étant fichées dans le panneau, au fond des trous borgnes.In an advantageous embodiment of the invention, the fixing of the tufts of threads in the blind holes is carried out by means of staples, which are stuck in the wall of the blind holes. In a preferred embodiment of this embodiment of the invention, the tufts of threads are bent and overlapped by the staples, which are stuck in the panel at the bottom of the blind holes.

Dans l'élément selon l'invention, il est préférable que les trous borgnes soient répartis de manière sensiblement uniforme sur une face du panneau à claire-voie, entre les vides de celui-ci. Cette forme de réalisation particulière de l'invention est de nature à uniformiser les propriétés glissantes de la piste de glisse.In the element according to the invention, it is preferable that the blind holes are distributed substantially uniformly on one side of the slatted panel, between the voids thereof. This particular embodiment of the invention is likely to standardize the sliding properties of the gliding track.

Dans une autre forme de réalisation particulière de l'élément selon l'invention, les vides du panneau à claire-voie sont sensiblement carrés et répartis de manière sensiblement uniforme et le panneau est de forme générale sensiblement rectangulaire et comprend, sur au moins un côté, un organe de connexion mécanique à un élément analogue juxtaposé. L'organe de connexion peut être un organe de connexion amovible ou un organe de connexion inamovible. Les organes de connexion amovibles sont préférés, car ils permettent d'assembler et de désassembler des panneaux à volonté. Un exemple d'organe de connexion susceptible de convenir dans la présente invention, est décrit dans le document GB-1418458 .
Les éléments de piste artificielle conformes à la forme de réalisation qui vient d'être décrite se prêtent bien à l'assemblage de plusieurs panneaux pour réaliser une piste artificielle de glisse.In another particular embodiment of the element according to the invention, the voids of the slatted panel are substantially square and distributed in a substantially uniform manner and the panel is generally of substantially rectangular shape and comprises, on at least one side , a mechanical connection member to a similar element juxtaposed. The connection member can be a removable connection member or an irremovable connection member. Removable connecting members are preferred because they allow assembling and disassembling panels at will. An example of a connection member that may be suitable in the present invention is described in the document GB-1418458 .
The artificial track elements according to the embodiment which has just been described are well suited to the assembly of several panels to achieve an artificial gliding track.

L'invention concerne dès lors également une piste de glisse, comprenant un assemblage d'éléments conformes à l'invention, tels que décrits plus haut. Il concerne spécialement une piste de glisse de ce type, pour la pratique du ski.The invention therefore also relates to a gliding track, comprising an assembly of elements according to the invention, as described above. It concerns especially a gliding track of this type, for the practice of skiing.

Dans la piste artificielle de glisse selon l'invention, le pouvoir glissant de la piste, défini par son coefficient global de frottement, va être choisi en fonction des paramètres d'utilisation, notamment de la pente de la piste. Dans une forme de réalisation particulière de la piste selon l'invention, celle-ci comprend une assemblage de panneaux dont les coefficients de frottement ne sont pas les mêmes pour tous les panneaux. Cette forme de réalisation de l'invention trouve des applications pour des pistes dont la pente n'est pas uniforme ou présente une successions de zones en pente et de zones sensiblement horizontales. Pour la construction de telles pistes, on peut par exemple utiliser des panneaux à faible coefficient de frottement dans les zones horizontales ou de faible pente et des panneaux à coefficient de frottement plus important dans des zones à forte pente. Cette forme de réalisation de l'invention trouve une autre application dans la construction de pistes de glisse (notamment de ski) servant à l'écolage de skieurs, en permettant d'associer des zones à faible coefficient de frottement et des zones à coefficient de frottement plus élevé, selon un schéma prédéterminé.In the artificial gliding track according to the invention, the sliding power of the track, defined by its overall coefficient of friction, will be chosen according to the use parameters, in particular the slope of the track. In a particular embodiment of the track according to the invention, it comprises an assembly of panels whose coefficients of friction are not the same for all panels. This embodiment of the invention finds applications for tracks whose slope is not uniform or has a succession of sloping zones and substantially horizontal zones. For the construction of such tracks, it is possible for example to use low friction panels in horizontal areas or low slope and panels with higher friction in areas with steep slopes. This embodiment of the invention finds another application in the construction of ski slopes (especially skis) used for skiers' schooling, by allowing to associate zones with a low coefficient of friction and zones with a higher coefficient of friction, according to a predetermined pattern.

La piste de glisse selon l'invention trouve des applications comme substitut à des pistes de neige ou de glace pour la pratique de la luge, du ski, du motoski ou d'autres engins convenant pour la pratique des sports d'hiver.The gliding track according to the invention has applications as a substitute for snow or ice tracks for sledging, skiing, motorcycles or other gear suitable for the practice of winter sports.

L'élément de piste artificielle de glisse selon l'invention et la piste de glisse selon l'invention présentent divers avantages, parmi lesquels les plus significatifs sont l'obtention d'un pouvoir glissant optimum et réglable facilement et à volonté en fonction de divers paramètres (par exemple la topographie du terrain auquel on destine la piste artificielle de ski ou l'aptitude des utilisateurs à évoluer sur une piste de glisse), la grande adaptabilité de la piste à la topographie, aux dimensions et à la forme du terrain sur lequel on prévoit de la construire, la possibilité de substituer facilement des fils usagés (ou inadaptés à l'utilisation de la piste de ski) par d'autres fils de constitution différente.The artificial gliding track element according to the invention and the sliding track according to the invention have various advantages, among which the most significant ones are obtaining an optimum and easily adjustable sliding power at will according to various parameters (for example the topography of the terrain for which the artificial ski slope is intended or the ability of users to move on a gliding slope), the great adaptability of the track to the topography, the dimensions and the shape of the terrain on which is planned to build, the possibility of easily replace used son (or unsuited to the use of the ski slope) by other son of different constitution.

Description détaillée de modes de réalisation particuliersDetailed description of particular embodiments

L'élément de piste artificiel de glisse représenté aux figures 1 à 3 comprend un panneau à claire-voie 1. Le panneau à claire-voie 1 comprend un quadrillage de longerons 2 qui s'entrecroisent à angle droit pour former entre-eux des vides 3 sensiblement carrés, présentant tous sensiblement la même superficie. Le panneau est un monolithe en polyéthylène linéaire, basse densité, obtenu au moyen d'un procédé de moulage par injection.The artificial gliding track element shown in Figures 1 to 3 comprises a slatted panel 1. The slatted panel 1 comprises a grid of longitudinal members 2 which intersect at right angles to form between them substantially square voids 3, all having substantially the same area. The panel is a linear low density polyethylene monolith obtained by means of an injection molding process.

Le panneau 1 est destiné à être posé sur un support, généralement le sol d'une salle de sport ou, plus généralement, à l'extérieur pour former une piste artificielle de glisse (par exemple une piste artificielle de ski). Sur sa face supérieure, le panneau 1 est percé de trous borgnes 4, uniformément répartis sur la superficie des longerons 2. Dans la forme de réalisation représentée à la figure 2, les trous borgnes 4 sont répartis en trois rangées rectilignes sur chaque longeron 2. En variante, les trous borgnes pourraient être répartis d'une autre manière sur les longerons 2, par exemple d'une manière non uniforme ou non rectiligne ou en quinconce.The panel 1 is intended to be placed on a support, generally the floor of a sports hall or, more generally, outside to form an artificial gliding track (for example an artificial ski track). On its upper face, the panel 1 is pierced with blind holes 4, uniformly distributed over the area of the longitudinal members 2. In the embodiment shown in FIG. figure 2 , the blind holes 4 are distributed in three straight rows on each beam 2. Alternatively, the blind holes could be distributed in another way on the longitudinal members 2, for example in a non-uniform or non-rectilinear manner or staggered.

Dans chaque trou borgne 4 se trouve insérée une touffe de fils 5.In each blind hole 4 is inserted a tuft of son 5.

La figure 4 montre une touffe de fils 5. Pour obtenir la touffe de fils 5, on dispose plusieurs fils 6 côte à côte, pour former un faisceau ou une botte de fils et on plie le faisceau de fils 6 de manière à rabattre leurs extrémités 7 l'une sur l'autre. Les fils 6 sont avantageusement des fibres monolithiques en téréphtalate de polybutène, obtenues par un procédé d'extrusion et leur nombre, dans chaque touffe 5, se situe par exemple entre 5 et 100 et est idéalement de 10 à 50.The figure 4 shows a tuft of son 5. To obtain the tuft of son 5, we have several son 6 side by side, to form a bundle or a bundle of son and we bend the son bundle 6 so as to fold their ends 7 the one on the other. The son 6 are advantageously monolithic fibers polybutene terephthalate, obtained by an extrusion process and their number in each tuft 5 is for example between 5 and 100 and is ideally from 10 to 50.

Les touffes de fils 5 sont introduites dans les trous borgnes 4, de manière que les extrémités 7 des fils fassent saillie au-dessus du panneau 1 et que leur zone de pliage 8 soit au fond du trou borgne 4. Chaque touffe de fils 5 est fixée mécaniquement dans son trou borgne 4 au moyen d'une agrafe 9. A cet effet, l'agrafe 9 est profilée en U, chevauche la zone de pliage 8 des fils et est fichée dans le panneau 1 au fond du trou borgne 4.The tufts of threads 5 are introduced into the blind holes 4, so that the ends 7 of the threads protrude above the panel 1 and their folding zone 8 is at the bottom of the blind hole 4. Each bundle of threads 5 is mechanically fixed in its blind hole 4 by means of a staple 9. For this purpose, the staple 9 is U-shaped, overlaps the bending zone 8 of the son and is stuck in the panel 1 at the bottom of the blind hole 4.

Le panneau 1 comprend par ailleurs, à sa périphérie, des organes de connexion (non représentés), destinés à l'attacher à des panneaux sensiblement identiques qui lui seraient juxtaposés. Les organes de connexion sont amovibles, pour permettre d'assembler et de désassembler à volonté les éléments juxtaposés.The panel 1 further comprises, at its periphery, connecting members (not shown), intended to attach to substantially identical panels that would be juxtaposed. The connecting members are removable, to allow to assemble and disassemble at will juxtaposed elements.

Les figures 5 et 6 montrent un tapis 10 en une matière élastique, par exemple en élastomère ou en une mousse en un polymère de synthèse, par exemple une mousse de polyuréthane. Le tapis 10 présente sur une face une série de bourrelets 11 séparés par un réseau de cannelures orthogonales 12. Le tapis 10 est destiné à être posé sur le sol, sous un panneau 1, de telle sorte que les bourrelets 11 pénètrent dans les vides 3 du panneau 1 et affleurent la face supérieure du panneau, tandis que les longerons 2 s'insèrent dans les cannelures 12.The figures 5 and 6 show a belt 10 made of an elastic material, for example an elastomer or a foam made of a synthetic polymer, for example a polyurethane foam. The belt 10 has on one side a series of beads 11 separated by a network of orthogonal grooves 12. The belt 10 is intended to be placed on the ground, under a panel 1, so that the beads 11 penetrate the voids 3 panel 1 and flush with the upper face of the panel, while the longitudinal members 2 fit into the grooves 12.

La figure 7 montre une partie d'une piste artificielle de glisse conforme à l'invention. La piste est formée de la juxtaposition de quatre éléments de piste du type de celui décrit plus haut, en référence aux figures 1 à 4. Dans la piste de la figure 5, les panneaux 1 des éléments sont disposés côte à côte, de telle manière que les longerons 2 de chaque panneau 1 soient disposés dans le prolongement de longerons correspondants des panneaux 1 qui l'entourent. Les panneaux 1 sont par ailleurs dimensionnés de manière que leur assemblage réalise une continuité uniforme dans la distribution et les dimensions des vides 3 des quatre panneaux 1. Les panneaux 1 sont solidarisés au moyen des organes de connexion dont ils sont munis.The figure 7 shows a portion of an artificial gliding track according to the invention. The track consists of the juxtaposition of four track elements of the type described above, with reference to the Figures 1 to 4 . In the track of the figure 5 the panels 1 of the elements are arranged side by side, so that the longitudinal members 2 of each panel 1 are arranged in the extension of corresponding longitudinal members of the panels 1 surrounding it. The panels 1 are further dimensioned so that their assembly achieves a uniform continuity in the distribution and the dimensions of the voids 3 of the four panels 1. The panels 1 are secured by means of connection members which they are provided.
