Abstract

The Alpine-type skis are exclusively manoeuvrable, guaranteeeasy bend performance and turnings on different snow surfaces atdifferent slopes and enable the establishing of control, stabilityand confidence in the skiers. The skis have side twist determiningminimum width in their middle which width increases towards theirfore and rear ends. The radius of the "waistline" of the ski isfrom 16 to 19 cm, and its shape is elongated and increases theline of contact with the show.

Description

Field of the art

The invention relates to alpine skiing with extremely high maneuverability, defining the easy execution of turns and turns on different snow surfaces at different slopes and providing the ability to control, stability and confidence of skiers.

Alpine skiing according to the invention will be used as an effective means of training for beginners and intermediate skiers and as a means of fun for good skiers in overcoming snowflakes and distances in fresh snow.

State of the art

Alpsian skis are known to have a lower curve, a lateral curve and a particular waist, a narrower middle part in which the lateral curve determines the minimum width of skis where the width of the skis increases both in the direction of the rear edge of the skis, so and in the direction of the front end of the skis (1).

The disadvantage of the famous alpine skiing is the relatively small length of the waist of the skate, defined by the large radius of the waist on the skate, which makes it difficult for the skier to balance and turn.

Technical nature

The essence of the invention consists in the creation of alpine skiing with unknown hitherto high maneuverability, the radius of the waist of the ski for the length range from 180 to 205 cm is in the range of 16 to 19 meters and determines the widths at a peak in the range of 104 to 109 mm, a medium in the range of 64 to 65 mm and a fifth in the range of 91 to 98 mm, and the shape of the waist of the sketch is elongated, increasing the line of contact with the snow.

The advantage of the invention lies in the fact that the proposed alpine ski design creates the possibility for easy, unimpeded control and control of the skis due to unknown hitherto high maneuverability resulting from improvements in the design of skis consisting in the realization of an extended waist on the skate , increasing the line of contact with the snow, as well as optimal widths at the top, middle and heel as a result of the small radius of the waist of the scaffold used in its formation.

This alpine ski design according to the invention helps the skier to overcome the reaction forces of the support acting against it by significantly reducing and distributing them on a larger surface.

The elongated waist of the sketch makes it easy to make turns and turns because less effort is required on the part of the skier when cornering as a result of increased ski stability due to a larger line of contact with the snow.

As a result of the reduction of the waist radius, the radius ranges on a shorter stretch and there is excellent trapping in the passage of icy areas due to lack of long-distance slipping and concentration of effort at one point.

The elongated waistline, the optimal top and bottom widths and the heavily-staggered latitudes provide minimal sinking capability and unobstructed snow handling due to the presence of significantly larger surfaces on which the forces are distributed, and the weight of the body.

Description of the attached figures

An exemplary embodiment of alpine skiing, which explains the essence of design changes, is shown in the appended figure 1, which is a top view of an alpine skete with a new design.

Examples of implementation

In Fig. 1 is a variant of a new alpine ski design featuring high performance and stability.

Examples

Alpine skiing, having a curvature on the lower surface, a lateral curve and a particular waist, a narrower middle part in which the strain curve determines the minimum width A of the skis. The width B of the ski increases in the direction of the rear edge of the ski and the width C of the ski increases in the direction of the front edge of the skis. The waist radius of 205 centimeters is 18 t and defines the width C = 110 mm, width A = 64 mm and width B = 98 mm. These dimensions of the ladder widths in A, B and C are not fixed and may vary depending on a variety of factors such as sketch structure, plasticity, stiffness and others in the range of plus / minus 1 mm.

For better illustration of the ski objects of the invention, examples of comparison are shown in Table 1.

Dimensions measure the length using the end of the skis as a starting point for making the measurements.

Application / Use / of the Invention

The skis according to the invention can satisfy the needs and requirements of both beginner skiers and professional athletes.

Upon entering a bend, the skier turns the skis at an angle to their current position by turning the skis and changing the body position while simultaneously applying force on the skis. At the same time, they diverge in the desired direction from the tangent to the curve arc, as at the moment when the skis are directed in the direction of the tangent, the force of the support of the support, the total force from the angular forces and the weight of gravity, it reaches 25 values. In order to maintain ski control at this point, it is necessary to absorb a large part of the increased reaction of the support, as in the course of the turn the skier transferred more weight in one way or another on the front or back of the skis. Increasing the force in the direction of the length of the skis along their edges and the deviation of the skier's body from its original position preserves the expected turning arc. The difficulty in balancing is that in the final phase of the reversal, the skier is bent more and more, which in combination with the increased response forces of the support makes it difficult to keep balance and return to the starting position for the next turn. In addition, when cornering, angular forces act on long skids and cause slipping, especially on an icy or hard surface.

With the prior art, a certain amount of energy is absorbed by the reversal support reaction in the event of a reversal without serious disruption of the desired reversing arc, with less pressure being applied by the skier applied at the end of the skid due to the absorption of part of the reaction on the back of the skis and the arch, allowing the skier to stay more upright and balanced on the skis.

In alpine skiing according to the invention, the skier remains fully upright and balanced on skis all the time for the following reasons.

The small radius of the waist of the skein requires minimal effort applied by the skier along the skis in the direction of their ends and a minimum deviation of their body due to the fact that the arc of the waist on the sketch is very close to the arc of the bend.

The strength of the support response, a cumulative force of gravity and angular forces, respectively, is considerably smaller due to the above considerations and is absorbed on much larger contact surfaces in the direction of the length of the skeet, with a substantial portion of it accumulating in the form of elastic forces in the squeegee due to its increased elasticity resulting from the maximum narrowing in the middle and the maximum widening at its ends. The design of the skis according to the invention can be absorbed and stored in the ski significantly more energy in turning, without breaking the curve arc at very low pressure applied at the edges of the skate.

The slip of the skis when running on icy surfaces or smooth slopes becomes nearly zero because of shortening the action of angular forces on the skein, concentrating the forces at one point and snapping a very short stretch.
