Definitions

  • the invention relates to a sliding element for track systems and tracks for winter sports disciplines, preferably for a run-in track for ski jumping systems with a profiled sliding surface and a method for its production.
  • the non-optimal lane conditions lead to disadvantageous effects on the learning behavior of the jumpers, especially in the starting position and in the jump, especially in the junior area.
  • plastics in the form of plastic mats or plastic profile elements could not prevail even at cross-country skiing events.
  • a start-up system for ski jumping and a ski track element therefor are also known, in which a metal track is supercooled or iced up.
  • the lateral track limitation of the metal inrun track is made of plastic.
  • the system is with a cooling system fitted. It is also possible to freeze and prepare the inrun track in low-snow and warm weather conditions.
  • the sliding properties achieved correspond approximately to those of winter conditions.
  • the construction and operation of such a start-up system is very expensive.
  • constant track conditions cannot be made possible for all athletes over the entire duration of the competition.
  • a run-up track for ski jumping which has ski tracks, the sliding surface of which is made of profiled porcelain plates to reduce the contact area with the ski.
  • the structure of this track is designed so that the porcelain plates are arranged on an aluminum mounting rail. They are fixed there by means of clamping plates, a fastening and guide profile made of plastic being arranged between these and the porcelain plate. It is possible to arrange additional devices such as water spray devices between the ski tracks. It is necessary to arrange the entire web on a very stable base plate. With this it is then attached to the hill itself.
  • This structure of the track is very complex to assemble and also requires a high cost.
  • the invention has for its object to provide a sliding element for track systems and tracks for winter sports disciplines, preferably for a run-in track for ski jumping systems, with a profiled sliding surface and a method for its production, which is good in a year-round operation and good for a long time Has constant sliding properties for a period of time, can be easily installed on known substructure constructions and requires little maintenance.
  • the object is achieved in that the sliding element is designed as a one-piece, self-supporting body, on the sliding surface of which convex sliding segments which consist of a glass flow are arranged.
  • the design of the sliding element as a one-piece, self-supporting body means that it can be used universally with a versatile design.
  • the sliding element can be attached in a simple manner without additional guide and stabilizing elements. There are no special requirements for the substructure. With such a sliding element it is therefore possible to design very different types of lanes and tracks, such as inrun tracks for ski jumping facilities, tracks for cross-country skiing, but also large areas, such as those required for curling. It can be used in a variety of other winter sports disciplines.
  • convex sliding segments made of glass flow ensures a long service life and constant properties of the sliding elements ensures that the same sliding conditions for the sliding process are present even if the same is worn over a longer period of time.
  • the sliding segments protrude from the sliding surface 0.3 to 5 mm, preferably 0.5 to 1 mm, and the ratio of the area of the sliding segments to the sliding surface is 1: 120 to 1:20, preferably 1 : 75 to 1:60.
  • the sliding surface including the sliding segments With a glass flow, it is possible to further improve the sliding conditions.
  • the sliding surfaces are laterally delimited by rims.
  • the sliding elements can have openings for receiving fastening elements.
  • the body of the sliding element can consist of a densely fired ceramic material, and the glass flow can be formed by a glaze. But it is also possible that the body of the sliding element made of a metallic material exists and the glass flow is formed by an enamel.
  • the use of the materials depends in particular on the desired properties of the track systems and trains. It is therefore possible to meet individual requirements as far as possible.
  • a method for producing a sliding element according to the invention is characterized in that, after the shape of the body of the sliding element, drops consisting of glass flow are applied and dried on the sliding surface in a predetermined grid, where they form the convexly shaped sliding segments, and then the entire sliding surface including the sliding segments are covered with a glass flow and then the sliding element is fired.
  • the entire sliding surface including the sliding segments By coating the entire sliding surface including the sliding segments with a glass flow, it is possible to achieve optimal sliding properties on the entire sliding surface.
  • the inside of the shelves can also be covered with glass flow, which practically has a sliding surface in the form of your limitation form.
  • a sliding element 1 shows a sliding element 1.
  • This has a one-piece, self-supporting body, which can consist of ceramic, but also of metal.
  • the upper surface of the sliding element 1 forms a sliding surface 2.
  • convex sliding segments 3 which consist of a glass flow. They are distributed over the entire sliding surface 2, with only enough sliding segments 3 to be provided that the lateral stability and the smooth running of the skis or other winter sports equipment are guaranteed, but the frictional resistance is as low as possible.
  • twelve sliding segments 3 can be arranged on a 600 cm2 sliding surface 2. If the basic body consists of a metal, the glass flow is an enamel and, for a basic body made of ceramic, a glaze. In the embodiment shown in FIG. 1, the sliding surface 2 is delimited laterally by rims 8.
  • the sliding element 1 has openings 4, which are used for fastening it to a substructure 5 (FIG. 2).
  • a substructure 5 FIG. 2
  • the attachment of the sliding element 1 with wood screws on a wooden base is shown schematically. It is, of course, also possible to attach it to another substructure 5, e.g. made of concrete using stone screws. It is essential for the attachment that the sliding elements 1 can be attached in a non-slip manner and have an all-round support so that they are essentially not exposed to bending loads and a smooth track or surface can be built up.
  • webs 7 are arranged on the underside of the sliding element 1, which preferably extend in the longitudinal direction of the sliding element 1 over its entire underside.
  • a narrow contact surface of the webs 7 makes it easier to align the sliding elements 1 in the case of an uneven substructure.
  • FIG. 3 shows a further embodiment of a sliding element 1.
  • this has cutouts 6 on its underside, in which heating elements can be arranged.
  • the structure of a run-up track for ski jumping systems is shown schematically.
  • the sliding segments 1 rest with their webs 7 on the base of the ski jumping system and extend over several individual elements of the same, for example transversely to the running direction arranged wooden slats.
  • the sliding elements 1 are then fastened to these by means of fastening elements arranged in their openings 4.
  • By supporting the sliding elements 1 on several individual elements of the substructure a good formation of the track is ensured even with simple ski jumps with a substructure 5 made of wooden slats. If the substructure consists of a one-piece concrete surface, the track structure will of course continue to be simplified.
  • the jumper In the inrun track for ski jumping systems shown in FIG. 4, the jumper is able to maintain a steady and safe downhill position through precise guidance of the ski in the lane, good sliding properties and an optimal jump. This creates the prerequisites for good flight posture and long jump distances.
  • sliding elements 1 without ribs 8. This is necessary if a surface is to be formed by placing the sliding elements 1 in the longitudinal and lateral directions, as can be used, for example, for curling.
  • the outer sliding elements 1, which limit the area, can have a rim 8 on their outer edge.
  • the method for producing the sliding element 1 with or without a rim 8 is that the self-supporting body of the sliding element 1 is manufactured in a manner known per se by extruding, casting or pressing a ceramic mass. It is advantageous to use a densely sintered ceramic material as the material for the one-piece self-supporting body, for example according to DIN 40 685 Ker 110.2 or according to IEC 672-3 C 120. It is also the arrangement of the webs 7 for such a ceramic body is particularly advantageous since they serve to stabilize the same during firing. After the body of the sliding element 1 has dried, the sliding segments 3 are applied as glaze drops and these are also dried. Subsequently, the sliding surface 2 with the sliding segments 3 including the edge limitation is again covered with a glaze film and the sliding element 1 is then sintered tightly at a firing temperature suitable for the ceramic.
  • the self-supporting body is produced by molding processes known per se.
  • the sliding segments 3 made of enamel are also applied in the form of drops and after drying, a uniform enamel layer is again applied over the sliding surface. After this layer has dried, the enamel is baked.
  • base and top enamels can be used.
