Abstract

Alpine skis are extremely maneuverable, provide easy execution of turns and turns on different snow surfaces at different slopes and create the possibility of control, stability and confidence of skiers. The skis have a lateral curve, determining a minimum width in their middle, which width increases in the direction of their rear and front ends. The radius of the waist of the ski is from 16 to 19 cm, and its shape is elongated and increases the line of contact with the snow.

Description

TECHNICAL FIELD

The invention relates to Alpine skis with extremely high maneuverability, determining the easy execution of turns and turns on different snow surfaces, at different slopes and creating the ability for control, stability and confidence of skiers.

The alpine ski subject of the invention will find application as an effective means of training beginners and intermediate skiers and as a means of entertaining good skiers in overcoming unpaved snowy terrain and overcoming distances in fresh snow.

BACKGROUND OF THE INVENTION

There are known alpine snow skis with a lower surface bend, a lateral bend and a special waist - a narrow middle part in which the lateral curve determines the minimum width of the skis as the width of the skis increases in the direction of the back edge of the skis. (1) USP 4 715 612

The disadvantages of the known alpine snow skiing are: the relatively small length of the slope of the slope and the small widths at the top and heels close to the widths of the standard alpine skis obtained as a result of the large radius of the slope of the slope, of the order of 48 m, suggesting difficulties for the skier in balancing when making turns.

TECHNICAL NATURE

The essence of the invention is the realization of Alpine skiing with extremely high maneuverability, having a curvature of the lower surface, a lateral curvature and a special waist - a narrower middle part in which the lateral curvature defines a minimum width of the skis. The width of the skis increases in the direction of the back and front of the skis. The waist radius of the slope for the range of lengths from 170 to 205 cm is in the range from 16 to 19 meters and determines the width at the tip in the range from 104 to 111 mm, the medium in the range from 59 to 65 mm and the fifth in the interval from 89 to 98 mm, and the shape of the waist of the slope is extended increasing the line of contact with snow.

The advantage of the invention is that the proposed Alpine skiing design allows for easy, unobstructed skiing management and control due to their extremely high maneuverability as a result of improvements in ski design resulting in extended sloping waistline and optimum widths at the apex, midline and heel as a result of the small waist radius of the slope used to shape it. This Alpine ski design of the invention will help the skier overcome the forces the reaction of the support acting against it by significantly reducing it and distributing it over a larger surface. The extended slope of the slope contributes to the ease of turning and turning, since significantly less effort is required by the skier to turn as a result of greater stability of the slope due to the greater contact with snow.

As a result of the decrease of the waist radius of the slope, the radius range ends in a shorter section and there is an excellent finish when crossing the icy sections due to the lack of long-range slip and the concentration of effort at one point.

The extended slope of the slope, the realized maximum widths at the top and the heel, as well as the highly narrowed environment determine the minimum possibility of sinking of the slope in the turning and unobstructed management of the skis in the unbroken snow due to the presence of significantly larger surfaces on which the forces are distributed. and body weight.

EXAMPLES FOR IMPLEMENTATION

In FIG. 1 shows a variant of a new design of Alpine skiing featuring high performance and stability.

Examples:

Alpine skis having a curvature on the lower surface 1, a lateral curvature 2 and a special waist 3 - a narrower middle part in which the lateral curvature defines a minimum width A of the skis. The width B of the skis increases in the direction of the rear end 4 of the skis and the width C of the skis increases in the direction of the front end 5 of the skis. The waist radius of the slope 6 for 205 cm length is 18 meters and determines width C = 110mm, width A = 64mm and width B = 98mm.

For a better illustration of the advanced ski subject of the invention, comparison examples are given in Table 2.

APPLICATION / APPLICATION / INVENTION

The skis of the invention can satisfy the needs and requirements of both novice skiers and professional racers.

When turning, the skier turns the skis at an angle to their current position, by turning the skis and changing the position of the body, while simultaneously applying force to the skis. In this case, they deviate in the desired direction in the tangent to the arc of the bend, and at the moment when the skis are directed in the direction of the tangent, the reaction force of the support ^ the total force from the angular forces and the gravity increases very high and reaches high values. In order to maintain control of the skis at this point, it is necessary to absorb much of the '· * · increased reaction of the support, and in the course of the turn the skier transferred more weight one way or another to the front or back of the ski. skiing. By increasing the force in the direction of the length of the skis in the direction of their edges and the deviation of the skier's body from its original position, the expected inversion arc is maintained. The difficulty in balancing is that in the lateral phase of the turn, the skier turns more and more bent, which in combination with the increased reaction force of the support makes it difficult to maintain equilibrium and return to the starting position to start the next turn. In addition, angular forces act on large length skis during inversion and cause slippage, especially on icy or hard surfaces.

Some energy is absorbed by the state of the art from the reaction of the support during inversion without severely disrupting the desired inversion arc, applying less pressure from the skier applied at the end of the slope to absorb some of the the reaction of the support at the back of the skis and the arch, which allows the skier to stay more upright and balanced on the skis.

In the Alpine ski subject of the invention, the skier stays upright and balanced on the skis at all times for the following reasons:

The small radius of the slope of the slope requires minimal effort by the skier along the length of the skis in the direction of their belts and minimal deviation of his body because the arc of the waist of the slope is very close to the arc of the bend.

The reaction force of the support, the total force of the force of gravity and the angular forces, respectively, are considerably smaller for the reasons stated above and are absorbed on very large contact surfaces along the length of the slope, and a considerable part of it accumulates in the form of elastic forces within the ski itself, due to its increased elasticity resulting from maximum narrowing in the middle and maximum expansion at its edges. With the help of the ski design, the object of the invention can be absorbed and stored in Kittel significantly greater amount of energy during Mr.? turning without breaking the arc of the turn at very little pressure applied at the ends of the slope,

Sliding of the skis when moving on icy surfaces or smooth slopes becomes almost zero due to the shortening of the line of action of the angular forces on the slope and concentrating the efforts at one point and ending a very short section.
