SI23239A - Transverse ski profile - Google Patents

Abstract

The transverse ski profile or the shown transverse ski profiles individually or in combination provide a maximum level of ski control under any conditions of use - both under competition conditions as well as for recreation purposes. Maximizing the control level does not only mean a faster and better skiing in the competitive sense but also means a higher level of security when avoiding any obstacles on the slopes. All presented and described ski profiles represent a completely new approach in producing skis as well as adapting of the skiing technique from the aspect of easier mastering of all conditions - competitive and recreational ones. By tests it is necessary to establish the optimum ratios and then exactly define the transverse profiles for the individual application purposes.

Description

CROSS-SKI PROFILE

The subject of the invention is a cross-sectional profile of the ski designed in such a way as to provide maximum handling in all conditions - maximum keeping the direction when running straight, as well as providing maximum grip and guidance of the ski when driving through turns, as well as transversely on a hill, regardless of the quality of the snow base.

The problem solved by the invention is the insufficient handling of the existing ski (s) - when running straight, as well as when cornering. There is a lot of gliding when cornering, which means a waste of time as well as a break from the ideal line. All these shortcomings come to the fore in competitive circumstances where every hundred counts. The decisive role in competitive conditions is only the competitor's superior technique and physical fitness. Through extensive analysis, the applicant has also found that heavier runners (with uniform driving technique) have a major advantage, providing greater pressure on the curbs and, consequently, greater impact of the curbs into the snow surface. This minimizes cornering glide and keeps the ideal running line (example; Alberto Tomba - 90 kg).

The applicant did not find any known solutions in such a comprehensive range of specificity and universality through research into the state of the art.

According to the invention, the problem of maximizing the conductivity of a ski in all conditions is solved by various shapes and interconnections of the cross profile of the ski. The invention will be described in the drawings illustrating Figure 1 cross profile of a catamaran ski with classic metal edges Figure 2 cross profile of a trimaran ski with classic metal edges Figure 3 cross profile of a trimaran ski with leading center ridge and specially shaped metal curbs Figure 4 cross-section of a ski in the shape of a trimaran with specially shaped curbs Figures 5,6,7,8,9 show different cross-sections of a ski with purpose-designed curbs.

Description of Figure 1;

Cross profile of the ski showing the body of the ski 1, the sliding surface 3 and the classic metal curb 2. This profile provides a reduction of running friction on a hard snow base, and a curved shaped sliding surface creates a support wedge in the section from the curb towards the center through turns. cross-section of the ski. When riding on softer grounds, the effect of creating a resistive wedge is even more pronounced, helping to guide the ski more accurately through the turn.

Description of Figure 2;

Cross-sectional profile of the ski showing the body of the ski 4, the trim surface 6 in the form of trimaran and the classic profile 5. The shape of the trimaran provides increased driving when straight due to the central ridge - the concave shaped sections of the sliding surfaces provide a support wedge in the snow surface when driving through turns. and in combination with a metal curb, they improve the precision of steering through a turn.

Description of Figure 3;

Cross-sectional profile of the ski showing the body of the ski 7, the trim surface 9 in the form of trimaran with a metal guide ridge 10 and a specially designed metal curb 8. The profile described provides absolute direction guidance when driving straight, • as the metal guide ridge acts as a skater. When traveling through turns, a specially shaped curb allows the ski to be pushed into the snow base (especially if it is very hard or icy), which prevents sliding when cornering. Scrolling through a turn means losing time and moving away from the ideal turn-by-turn line.

Description of Figure 4;

Cross-sectional profile of the ski showing the body of the ski 11, a trimaran shaped sliding surface 13 which transforms into a guide ridge of a metal curb 12, which represents the central support point of the curb or pivot when changing the inclination during cornering. The driving ridge 12 is imprinted into the snow surface during the turn, and then all the forces generated are distributed along the concave surfaces left and right of the leading ridge 1.

Description of Figure 5;

Cross-sectional profile of the ski showing the body of the ski 14, the sliding surface 16 and the step-shaped metal curb with emphasized angles and a guide ridge 15, which assumes its role at an inclination greater than 30 °. In increasing the tilting angle during cornering, both the guide ridge 15 and the end of the curb associated with the sliding surface 16 function. The guide ridge 15 also has the function of driving transversely over the hill, due to its specific shape, providing maximum handling with the smallest contact surface.

Description of Figure 6;

Cross profile of the ski showing the body of the ski 17, the sliding surface 19 and with the guide ridge 18 positioned slightly higher relative to the sliding surface. The function performed by the guide ridge 18 is similar to the description of the transverse profile of FIG. 5, in that the transitions from one shape to another are formed by different semicircular shapes.

Description of Figure 7;

Cross-sectional ski profile showing the body of the ski 20 the sliding surface 22 and the leading ridge 21. This cross-sectional profile of the ski results in a stronger increase in the stepped profile of the curbs and much more pronounced angles in the transitions from the sliding surface to the metal curb of the ski.

Description of Figure 8;

Cross-sectional profile of the ski showing the body of the ski 23 sliding surface 25 and with guide ridge 24. In this case, the profile of the metal curb of the ski is shaped so that from a stepped shape with emphasized angles, the curb profile provides absolute conductivity through turns, regardless of the tilting angle of the ski. relative to the snow surface. This means that as the tilting angle increases as well as the centrifugal force, the entire profile continuously neutralizes all the forces acting on the ski when traveling through a turn. This means that as the tilting angle increases when cornering, the surface of the metal edge in contact with the snow surface increases. The profile described allows maximum handling in all conditions, especially after driving on the hardest or icy surfaces.

Description of Figure 9;

Cross-sectional profile of the ski showing the body of the ski 26, the sliding surface 28 and the guide ridge 27, which is positioned slightly higher than the sliding surface 28, the end of which as the base of the metal curb is shaped such that the angle to the sliding surface 28 is greatly increased in the direction toward The body of the ski 26, which means that the transverse profile of the ski has two leading ridges 27 and 29. Also, this cross profile of the ski is intended for use in the most difficult driving conditions (very hard snow base and ice). The cross-sections of the ski described in Figures 5, 6, 7, 8, 9 can have sliding surfaces made in different combinations - catamaran, primary.
