Definitions
- the invention relates to a jumping ski for use in ski jumping and ski flying.
- a downhill ski provided with steel edges at the edge is also known, in which below the binding area (over approximately one third of the ski length) a running surface convexly convexly curved extends. Over the surface of this convexly curved tread additional steel edges are arranged in sections which are parallel to each other and a lateral "slipping" of this cross-section convexly curved tread - even on icy slopes - should prevent.
- the ski soles are provided with a special finish and the wax applied at elevated temperature (about 130 ° C), so that the wax can penetrate into the uppermost layer of the polymer and improves the hydrophobic properties of the PE outsole
- DD 270 011 B1 proposes changing the outsole of the skis, starting at the tip, continuously from a convex to a concave profile, in order to prevent the formation of a load-bearing air cushion underneath To reach concave outsole, so that with increasing speed in the run-up track a supporting air cushion is generated, which should reduce the sliding friction, so that by means of a higher start-up speed, a larger jump distance could be achieved.
- the invention has for its object to develop with the currently valid rules of the International Ski Federation compliant Sprungski with rectangular cross-section which eliminates the aforementioned disadvantages of the prior art, the optimum sliding properties of the jump skis achieved even without the use of special waxes, at the same time the jump conditions among the very critical "wet snow conditions" (ie the sliding and guiding properties at a filled in the area of the takeoff table with wet snow or meltwater gutter of the inrun track) significantly increased and achievable in ski jumping jump / flight distance, also positively influenced the landing, at the same time Strength properties and also the wear resistance of the skis significantly improved and also inexpensive to produce.
- this object is achieved by a skis with a rectangular Skiqueronce, a top flange (1), a lower flange (2) and a arranged between these Skikeil (3) and below the lower flange (2) arranged Ski sole (5), which is characterized in that sliding ribs (9) projecting beyond the plane of the ski sole (5) are arranged between the ski blade (6) and the ski end (7) over the entire length of the ski support surface, in the ski longitudinal direction in / on the ski sole (5).
- the solution according to the invention can thus surprisingly without any wax treatment of the PE outsole improved the sliding properties of the jump ski and the achievable jump / flight distance can be significantly increased. Since the ski underside according to the invention is also "grippier", the landing is also influenced positively. According to the invention arranged in the ski longitudinal direction on the ski sole sliding bars (9), for example, be glued, screwed or riveted. These embodiments are very cost-effective and are particularly suitable for young talent.
- the arranged in the ski longitudinal direction sliding webs (9) are secured in grooves (8) which are arranged in the ski sole (5).
- These sliding webs (9) can be fixedly arranged in the grooves (8), for example glued.
- each athlete can optimize the sliding bars used individually and, if necessary, even adapted to the respective ski jumping conditions, for example different Gleitstegformen or sliding bars made of stainless steel against chrome sliding bars, or against nickel vapor coated sliding webs (9) made of plastic, or to replace, for example, against segmented sliding webs with ceramic or glass surfaces.
- the grooves (8) have the shape of dovetail guides. As a result, a functionally reliable, heavy duty and at the same time replaceable at any time attachment of the sliding webs (9) is ensured.
- the cross section corresponds to a rectangular cross-section and is therefore also compliant with the currently valid regulations of the International Ski Federation. It is also essential to the invention that the height of the sliding webs (9) with which they extend beyond the ski sole (5) varies over the ski longitudinal direction, ie that the height of the sliding webs (9) relative to the plane of the ski sole (5), for example, from the end of the ski blade (6 ) can, for example, continuously increase or decrease until the end of the ski (7). It is also characteristic that the height of the sliding webs (9) with which they extend beyond the ski sole (5) varies over the ski direction.
- the sliding webs (9) and the middle sliding web (9) project in height over the intermediate sliding webs, so that by means of this solution, on the one hand, the guiding properties of the ski are improved and, moreover, by the higher surface pressure on the one hand acting as runners "higher” sliding webs (9) on the other hand, as well as due to the thereby forming in the start-up phase between the sliding webs under the ski air distribution on the other hand, the sliding properties can be further increased.
- FIG. 1 shows the bottom view of the skis according to the invention with two between the ski blade 6) and the ski 7 arranged in the ski longitudinal direction on the ski sole 5, the plane of the ski sole 5 superior sliding bars 9 is shown.
- FIG. 2 shows the bottom view of the skis according to the invention with three skids 9 arranged between the skiboot 6 and the ski end 7 in the ski longitudinal direction in the ski sole 5, the plane of the ski sole 5 projecting beyond.
- FIG. 3 shows the side view of the jumping skis according to the invention from FIG. 2 with the height of the sliding ribs 9 continuously decreasing over the ski length from the ski shovel 6 to the ski end 7 with respect to the plane of the ski sole 5.
- the height of the sliding webs 9 varies over the ski sole 5 between 0.5 mm and 3 mm.
- FIG. 4 now shows the section through a skip according to the invention according to FIG.
- FIG. 1 with a top chord 1, a bottom chord 2 and a ski boot 3 arranged between them, a ski sole 5 arranged below the bottom chord 2 and two glued on the ski sole 5 according to the invention
- Sliding webs 9 made of metal-coated plastic, which extend beyond the ski sole 5 by about 2 mm.
- This embodiment is very cost-effective and is particularly suitable for young talent.
- FIG. 5 shows a section through a skip according to the invention with a top flange 1, a bottom flange 2 and the side cheeks 4 and a ski boot 3 arranged between them, a ski sole 5 arranged below the bottom belt 2 and two sliding webs 9 interchangeable in the ski sole 5 according to the invention , which protrude the ski sole 5 by about 1 mm, with a selection of different sliding webs 9 which can be arranged in the dovetail grooves 8 of the same ski sole 5 to better match the respective ski to the individual needs of each jumper represented.
- dovetail grooves 8 is a functionally reliable, heavy duty and at the same time at any time "interchangeable" attachment of the sliding webs 9 guaranteed.
- FIG. 6 shows the section through a skip according to the invention with a top chord 1, a bottom chord 2 and the side cheeks 4 and a ski boot 3 arranged between them, a ski sole 5 arranged below the bottom chord 2 and two slits 8 arranged in the ski sole 5 according to the invention Sliding webs (9) in a further possible construction according to the invention.
