Definitions

  • the present invention relates to a ski or similar skating device (e.g. mono-ski, snowboard or similar) and is provided for enabling controlled sliding of an user over an area covered by snow or other covering suitable for sliding.
  • a ski or similar skating device e.g. mono-ski, snowboard or similar
  • the aim of the present invention is to create a ski or similar skating device, by which in addition to maintaining the benefits resulting from already known solutions also the torsional deformability of the forward portion should be essentially reduced without any additional or even disturbing supplements, so that on the one hand deflecting of the ski edges arranged adjacent to the running surface and herewith their sliding-down or the so called chattering could be avoided, and moreover on the other hand also vibrations resulting from said deformability could be essentially reduced.
  • the skis and similar skating devices are mainly treated and also manufactured as essentially flat, elongated and flexible beams having essentially flat rectangular cross-section.
  • the forward portion of the ski which is ordinary dominant with respect to the width, is provided by a tip on its end part and is ordinary rounded.
  • the rearward portion, the so called tail is ordinary essentially narrower than the forward portion, but on the other hand its width shall be at least slightly greater than the width of the central portion, which is foreseen for mounting appropriate binding means, which serve for attaching ski boots and herewith for establishing appropriate connection between the skis and the skier.
  • the bottom surface of the ski is the so called running surface, which is in its transversal direction ended by two edges extending each on its side of the said surface along the whole ski between the rearward portion (tail) and the forward portion (tip) thereof.
  • said edges are bent in both directions, namely in a direction one towards another and also in a direction from the ground away.
  • the edges are especially by skis also slightly bent respectively slightly arcuated along the whole length of the ski, which depends on the difference among the width of the forward, central and the rearward portion of the ski.

  • ski during maneuvering or turning by the ski and when slightly rotating the ski around its longitudinal axis (x) appropriate running of the ski along a non-linear trajectory may be achieved, which is defined as mainly circular movement by appropriate radius of curvature.
  • This may be especially effective when the width of the ski or similar skating device - when observing it in the plane parallel to the ground - in the central portion of the ski and therefore in the area of arrangement of the ski boot is essentially smaller than the width of the other portions of the ski.
  • the radius of curvature of the curved running line of the ski or similar skating device might be exactly determined with regard to the angle of rotation or deviation of the ski around its longitudinal axis.
  • the ground is never quite flat.
  • some manufacturers were occupied by a serious problem of determination appropriate flexibility respectively stiffness of the skis. Namely, it would be desirable that the edge cooperating with the ground shall be always in appropriate contact with the ground if possible along its complete length.
  • ski boot shall be mounted by appropriate binding means on a special plate, namely on the so called platform, which is mounted on the ski in such a manner, that relative movement between the plate and the ski in longitudinal direction is allowed.

  • appropriate deformability of the ski shall be achieved around the transversal axis perpendicularly to the longitudinal axis of the ski and simultaneously parallel to the ground, which shall be mainly independent from the way or mode of mounting a ski boot on the ski.

  • skis In the sense of the before mentioned problem concerning torsional deformability, a new construction of skis was created where in common all benefits resulting from the known solutions are maintained. On the other hand and especially thanks to surprisingly simple measure and moreover without any additional supplements a ski was achieved, by which possible torsional deformations of the forward portion around the longitudinal axis thereof are essentially reduced, and where moreover such a solution may be no doubt applied also by other skating devices, e.g. by snow-boards and similar articles.

  • the forward portion is to be understood as a portion available between the forward end part of the ski, the so called tip, and the central portion of the ski or similar skating device, where a ski boot can be mounted.

  • appropriate torsional deformability of the ski or similar skating device, especially of the forward portion thereof may be essentially reduced, so that also during turning or maneuvering the ski edge line is much more accommodated to the ideal or theoretical line desired by running along certain trajectory having certain radius of curvature, where running of the forward part of the ski away from the desired line during maneuvering can be mainly eliminated and where moreover occurring of vibrations can also be avoided.

  • a ski or similar skating device comprises appropriate running surface 4, which is arranged on the bottom side of the ski or similar skating device adjacent to the ground.

Thereby, each edge 5, 6 is bent in accordance with the appropriate flank line of the ski, i.e.
  • the forward portion 1 of the ski or similar skating device e.g. of a snow-board
  • the width (a) thereof - when observing it in a plane parallel to the ground - is smaller than the width (b) of the rearward portion 3.
  • Other features of the ski or similar skating device remain thereby mainly unchanged or are similar to those used by skis or similar skating devices known from the prior art, so that any other technical benefits resulting from known solutions may also be completely maintained.

Abstract

Cette invention se rapporte à un ski ou à un moyen de glisse similaire (tel qu'un monoski ou une planche de snowboard ou similaire), dans lequel les avantages résultants des solutions connues sont maintenus, mais, en plus et sans adjonction de quelque accessoire supplémentaire que ce soit, la déformabilité par torsion, notamment de la partie avant (1) du ski ou du moyen de glisse similaire, est essentiellement réduite. Ainsi, les arêtes (5, 6) du ski restent dans leur position correcte par rapport au sol, également lors des virages ou des manoeuvres, ce qui permet d'éviter tout écart par rapport à la bonne direction. En outre, également les vibrations affectant le ski lors des manoeuvres peuvent être essentiellement réduites, ce qui permet d'éliminer pour la majeure partie le fouettement des skis. Le ski ou le moyen de glisse similaire de cette invention possède une partie avant plus étroite (1), dont la largeur (a), observée dans le plan parallèle au sol ou à la surface de glisse (4), et à l'exception de sa partie terminale (1') ou pointe, est essentiellement inférieure à la largeur (b) de la partie arrière (2), à l'exception de sa partie terminale (2').
