Description

The invention relates to the field of artificial winter sports slopes or textile slopes.

 Artificial winter sports slopes are made of textile slopes and are e.g. Treadmills, flat pads or mats, for example made of plastic, which are provided for sliding driving with winter sports equipment such as skis or plastic toboggan. They have been known for several decades. There are a variety of systems with more or less good snowplough-like properties. These features include above all the leadership of the sports equipment, the sliding behavior, the absorption of shocks and the risk of injury of the coating.

 The installation of the flat supports or mats is carried out on cross-country skis, alpine skis, snowboards, ski jumping skis as well as with plastic sleds and snow tubes on the level or on sloping surfaces. The base on which the artificial sliding surface is laid can consist of natural ground, of concrete, etc. or of scaffolding components.

 In the present disclosure, the artificial winter sports slope is formed by a fabric. This fabric is characterized by good sliding and wear properties and a snow-like grip and can be used in the sports and leisure area with sports equipment such as cross-country skis, alpine skis, snowboard, ski jumping and sledging and sliding equipment.

 The fabric has a surface and is formed from weft threads and warp threads. The warp threads are made of particularly slippery and wear-resistant and cut-resistant plastic and form a kind of knobby structure by means of loops. The sports equipment sinks in this surface. This leads to the formation of a track in the surface of the tissue and thus to the leadership of the sports equipment. In particular, cornering with alpine skiing and snowboarding is possible, as on snow. Even a leg kick-off phase with skating skis is felt by the knobby loop structure as on snow.

 The fabric can be additionally stabilized or fixed with a back coating arranged underneath.

 Extensive downhill slopes and cross-country trails are composed of modules of the fabric. The modules are fixed to the floor by means of tabs and pegs. The modules are joined by gluing, welding, sewing, burettes or zippers.

 In one embodiment of the invention, the textile piste is placed on a downhill slope so that the weaving direction of the warp threads is arranged between 90 ° and 120 ° to the fall line of the downhill slope.

State of the art

Artificial winter sports slopes of the known type consist for example of injection-molded plastic lattice panels. On the approximately 2 cm wide webs of the grid equally high plastic pins are arranged, which should form the snow substitute function. For ski jumping and tubing applications, mats of lasts with attached plastic rods are known. There are also large mats made of tufted or woven pile fabric (eg GB 2 394 902 ) known. The pile thread consists of synthetic monofilament yarns or foil yarns. In FR 2 772 053 An artificial sliding surface based on a latticed knit fabric using monofilament yarns is described.

The utility model DE202011105370U1 describes a sliding fabric whose sliding surface of Polschlingen or tufts are formed. The pile loops consist of multifilament yarn or fiber yarn. The yarns are made of chemical fibers.

In the German patent application no. DE 2318415A a cross-country track for the classic technique is presented. The tracks are laid individually on the ground. Each track has as a sliding surface on plastic plates, which are provided with scales to increase the repulsion of stiction between ski and plastic plate during leg repulsion. The leadership of the track is done by open at an angle upwards laterally mounted square sections. In the profiles grooves for fixing the shape of the plastic plates are introduced.

In the German patent application no. DE 102005062711A1 is a sliding surface formed of knobs is described. The sliding surface is coated by fluoropolymers. In the wet test and the use of lubricants, a coefficient of friction of less than μ = 0.06 is achieved compared to the ski.

The German patent no. DE 288982A5 refers to artificial ski tracks especially for ski jumps. Described therein are special modules have the air outlet openings to create between ski and pad friction-reducing air cushion.

A base made of plastic with thereon arranged in lattice nubs Ceramic material is described in German utility model no. DE 20211137 U1 described.

In the further development described in the international patent application no. WO 2008151748 A1 the surveys can be exchanged. In the nubs material and shape is varied.

The German utility model DE 1871540 U describes a cross-country skiing track for training classical technique. The track consists of a plastic profile and has grooves on the sliding surface in the sliding direction.

 In all systems, irrigation of the sliding surface or treatment with lubricants reduces friction. However, irrigation must be permanent, as these systems have no water storage function.

• • Der Reibungswiderstand zwischen dem Sportgerät und der Oberfläche ist bei allen System sehr hoch;
• • Die Führungseigenschaften des Sportgerätes sind ungenügend;
• • Konstruktions- und materialbedingt liegt bei den meisten Systemen eine hohe bis sehr hohe Verletzungsgefahr vor;
• • Die Installation der Systeme ist zum Teil enorm aufwendig;
• • Bei dem Gros der System ist eine permanente Bewässerung notwendig, um ein passable Gleitwirkung zu erzielen;
• • Die Systeme weisen keine Wasserspeicherfunktion auf.

These artificial sliding surfaces are not sufficiently adapted to the requirements of the practice, which can be summarized in the following points:

• • The frictional resistance between the sports equipment and the surface is very high in all systems;
• • The guiding characteristics of the sports equipment are insufficient;
• • Due to design and material, most systems have a high to very high risk of injury;
• • The installation of the systems is sometimes enormously expensive;
• • For most of the system, permanent irrigation is necessary to achieve a smooth sliding effect;
• • The systems have no water storage function.
