Abstract

The invention relates to sports equipment and means mainly for moving on snow. A ski (or snow-board) has at least one bent end, an upper surface with a bearing stand for feet and a sliding surface embodied in the form of a single or several longitudinal cylindrical vaulted. The adjacent vaulted elements are separated by a comb with sharp bottom edge placed under the bearing stand. The comb gradually tapers at least one bent end of the ski. The comb gradually diminishes also to the rear end of the ski if it is bent like the head. In the preferred embodiment the sliding surface of the ski is formed with three longitudinal cylindrical vaulted elements. In this case, on the ski cross-section top points of two bordering vaulted elements coincide with bordering edges. The proportion between the height of the cylindrical vaulted elements and the distance between the bottom edges of the adjacent combs is not less than 1:2.5. The sliding surface can be formed with two longitudinal cylindrical vaulted elements. In this case, the sharp bottom edge of the comb is situated on the axis of symmetry of the ski.

TROUBLESHOOTING The invention is available for convenient equipment or other suitable equipment. for movement πο snow. in particular for skiing and snowboarding.

PREVIOUS LEVEL OF TECHNOLOGY

It is known that there is a youth (snowboard) with a bent upper end and a simple sliding slide with simple side ridges (patent υ8 Ν ° 5462304, 1995. Lateral ridges are designed to ensure greater stability when the snow is less, but they are not disadvantageous in preventing young people from shifting. Κροме τοгο. When moving, the ski is experiencing an increased collapse.

A ski is known for sliding in the form of a few parallel cylindrical bodies. Between adjacent arrays, a simple comb (patent

He 2000832. 1993). A good sliding format ensures stable lateral displacement. but it shows the seperate resistance to movement in the direct direction.

SUMMARY OF THE INVENTION

The ski of the proposed structure due to the form of the sliding speed increases the noticeable increase in the speed of the increase of the increase For this purpose, various competitive options of the invention can be used for skiing and running or skiing (many skis). as well as for skiing snow and snow skiing.

According to the invention, the ski has at least one folded end. The upper part of the property is with open area and sliding area in the form of a good condition. On a weekly basis, there may be one. The business area is a part of the outside world. for a direct, indirectly disabled person, or for a short-term active element. connecting the ski with snow or other transverse means. Adjacent arrays are separated by a base with an open lower area in the area of the open area. The comb is smoothly clearing at a height. changing the cross section from the other end to the close to the far end. With this reversal of the land, they lose their original form and orientation to the remaining areas of the ridge. As a result of movement, there is a gradual consolidation of snow through skiing. The result is a significant reduction in the long-term effect of the slip. 2

For skiing and running skis with a non-bent rear end, the ridge smoothly decreases and to the rear end of the ski. but it doesn’t completely disappear. In a snowboard that has a rear bent end, the comb smoothly descends on the net and on the rear end of the ski.

A preferable form is cylindrical. By and large, it was not only for a small cylinder, but also for other species. for example, an elliptical or paired cylinder. Alternatively, the execution of the information is in the form of a multi-prismatic accessibility. Β Anyway desirable. so that the difference between the height of the vault and the distance between the lower lower pockets of the adjacent combs was at least 1: 2.5. If you are skiing on one ski. It is limited to two combs.

The number of available apartments may be two or more, the number of dams between the doors in each case will be one less. With an optimal variant, a sliding conversion is possible both in the cylindrical vault and, moreover, in the cross section, the two other wartimes are related to The relationship between the average sizes (wide) of the middle and the side of the roof may be different depending on the destination of the ski. Едельн On a weekly occasion, virgins (benefits) may be expected. In addition, the outer crests of the ridges will not come out close to the vertical side skis.

Quick description of the drawings.

In Figure 1, an alpine ski is shown in a side view. It is noted the location of the center of the lateral resistance (CBS).

FIG. 2 shows a view of sloping terrain of a ski and shows the cross-sections of the cross-section Α-Α. BB and Β-Β. A Φ Fig. 3, Fig. 4 and Fig. 5 show the cross-sections of the ski Α-Α, BB and--и.

For clarity, the vertical scale has been increased compared to the horizontal one. Good wraps may also be available for snowshoes and skis for cross-sectional skiing, which are also marked with boulevards on the corresponding treadmills.

The dashed lines aa, cc and ee show the cross-sections of the ski for a variant of performance with degraded (missing) side arches.

In Fig. 6, a sliding skiing accessibility in an alternative ski is shown. 3

In Fig. 7, a side view of the snowboard is shown, having a bent front and rear ends.

Β The direction of the front bent end of the ski of the hump is smoothly decreasing to the total disappearance of the hitch (the comb "goes to net ^" ).

Β The direction towards the rear end of the ski is smoothly reduced, but the crest at the rear end of the ski does not disappear completely. Fig. 7, Fig. 8 and Fig. 12 are shown, which is for the option of a snowboard, which has front and rear bent ends. The dividing rooftops go smoothly on the net for the ends of the ski. With this type of change, the height of the comb in the direction of the predetermined end of the ski may be similar to the change in direction of the end of the skis, and may be neglected. If the sliding part is equipped with two separate cylindrical vaults, then the lower lower part of the comb is in good condition, as long as it is in good condition.

Well-known (Becker G.G. Introduction to the systems of the locality-machine. Μ .: “Emergency”, 1973, page 47; Congress J. Terrestrial communication. 1982: 74), the loading of the load on the load is subject to the appearance of the zone, in the short-term load it is in a heavy load. This area is comprised of a small number of participants, one of which is supplied with a non-defective wedge; At this point, two centered fans are reliably attached, two corresponding wedges are due, and there is no reason to forget about the arrears. The angles of the wedges depend on the type of tension and the tension of normal σ and the secondary stress and stress the so-called angle of internal stress φ. For different types of snow, the angle of internal friction lies in the range of 15 ° - 45 °, while the angle of 45 ° corresponds to ice.

When exposed to the snow in a cylindrical manner, the extensions to the front are inclined to the snow to the corner of φ. in the snow, an intense state is created that corresponds to the optimal ratio of \ UΟ 01/41886 Τ Κ

5 small and secondary stresses. This noticeably reduces the depth of skiing. In this case, depending on the snow density, the ski will be loaded to a different depth: to clear snow - to the top of the roof, to a very good extent - to a very small extent.

In order to reduce the direct ski movement, the combs, which are covered by the roofs, must be fully equipped with a non-skid ski.

The ski's resistance to transverse (lateral) displacement makes it more stable on the track and affects the handling. It depends on snow compres- sion to stresses through shear (cumulative τ) and compression (normal σ). are connected by the above relationship. Use of the ski offered by the user is encouraged to increase the restraint. This is also normal, which in turn leads to a sharp increase in the resistance to traffic and a decrease in the resistance to direct traffic.

If there are a few creepers, it is necessary to ensure that each of them is excluded, excluding the separation of zones, in which there is little snow. which is achieved by the location of the tombs at a distance of b, which increases the height of the b by at least 2.5 times, i.e. LI> 2.5 (Fig. 3 and 9).

It is experimentally determined that the approximate values of the angles α and β (Figs. 3 and 9) are, of course, almost 50 percent worse than the margin; (α + β) = 45 ° - 90 °, therefore, the angles α and β may not be equal between themselves.
