Definitions

  • the subject of the invention is a steel edge of a ski such as alpine ski, cross-country ski, off-slope ski and also a snowboard.
  • a technical problem solved by this invention is how to conceive steel edges of a ski which will improve the guiding of skis or a snowboard in turns whereby the steel edge may be implemented according to the invention on a new or an existing ski or a snowboard.
  • a skier is subject to much less vibrations on a hard, rib-like slope and in turns because the sharp steel edge cuts into the surface and thus allows skis to be guided almost or completely without sliding. It is clear from the above-mentioned that at off-slope and extreme skiing on hard packed or icy and extremely uneven surfaces, e.g. avalanche slopes, slopes covered with stones and rocks or even in the forest among trees and bushes, guiding of skis makes an essential contribution to the quality of skiing and safety. Alpine skiing on steep slopes clearly shows that the new properties of such a steel edge contribute to the safety of a skier and increase the level of still possible skiing.
  • the steel edge according to the invention on a snowboard offers the same improved properties.
  • Fig. 1 ski in side view
  • Fig. 2 transversal cross-section along the line II-II with Fig. 1 of the ski with the steel edge according to the invention
  • Fig. 3 transversal cross-section along the line III-III with Fig. 1 of the ski with the steel edge according to the invention
  • Fig. 4 transversal cross-section along the line IV-IV with Fig. 1 of the ski with the steel edge according to the invention.
  • a steel edge 1 is positioned on lateral edges 2 of an undersurface 3 of a ski 4 consisting of a shovel 5, a central part 6 and a tail 7 whereby the steel edge 1 runs along the entire length of lateral edges 2.
  • the steel edge 1 is placed in the ski 4 in a known manner with its thinner inner band 8 in a way that a sliding layer 9 of the ski covers it and thus binds into a ski.
  • the visible part of the steel edge 1 is provided with a groove 10 having in the transversal cross-section preferably a form of a semi-circle, the inclined cross-section 11 of which leans to a lateral surface 12 of the steel edge 1 and is straight and in contact with it in a sharp edge 13.
  • the lengths of cross-sections of the groove 10 in the central part 6, where the groove is even and deepest, and those of cross- sections in direction of the shovel 5 and the tail 7, where it continuously diminishes vary.
  • the length of cross-sections on the shovel and the tail without a groove has influence on the easiness of taming
  • the length of the central cross-section of the groove with the largest cross-section has influence on the degree of fitting to snow and ice.
  • An arch shaped cross-section of the groove allows turbulence of the cut snow in the groove.
  • the size of the cross-section of the groove can thus be subject of special tests for the adaptation of optimal properties with regard to the purpose of the ski and type of snow.
  • the sharp edge 13 or a sharp angle in the cross-section of the steel edge 1 has one more advantage, namely if it is used during normal skiing or even if a ski is serrated because having been damaged on a hard object, normally stones, it does not lose its property with respect to good guiding of a ski in a turn and to the prevention of sliding as was the case with the known steel edges.
  • the steel edges thus do not need to be sharpened often, which increase the life durability of the steel edges. Severe damage with serration which cannot be corrected by sharpening does not diminish the property of a ski to such an extent as with the known steel edge.
  • the steel edge according to the invention is shaped by sharpening with profile grinder in dimensions determined for the type and purpose of a ski. Sharpening can also be performed on a ready made ski.
  • the invention can therefore be applied also on old skis at a workshop.
  • a grinding device to this purpose can be manufactured with known means and in a known way on the basis of given data about the geometry of the groove.

Abstract

Carre d'un ski, tel qu'un ski alpin, un ski de ski de fond, un ski de saut et également un surf, qui résout le problème de la prise de virages et de la glisse sur différents types de pentes, que la neige soit molle, dure ou glacée. Ladite carre en acier est dotée sur sa surface adjacente à la face inférieure (3) du ski d'une rainure (10) à section transversale en forme d'arche (10'), une partie (11) de ladite section transversale inclinée vers la surface latérale (12) de la carre (1) en acier étant plate et en contact avec ladite surface latérale à un angle aigu α avec laquelle elle forme une arête vive (13) de la carre (1) en acier. L'angle α, qui change en permanence, mesure environ 45° dans la zone centrale (6) du ski (4), puis augmente de manière continue jusqu'à 90° vers une zone adjacente à la spatule (5) et au talon (7) du ski, et plus précisément avant la spatule (5) et le talon (7) où il se transforme en une surface plane se trouvant sur le même plan que la surface inférieure (3) du ski (4) ou du surf.
