Abstract

A ski (A), snowboard or skate edge (1) is implemented as any profile, preferentially as an L-profile, where it can be materially integrated with the core of the ski (A), snowboard or skate. The side face (2) of the ski edge (1) is executed with grooves (3) running cross to the virtual lengthwise axis of the ski edge (1), in which case the grooves (3) have different cross-sections and are arranged uniformly or more densely in groups along the length of the ski edge (1) and inclined under the angle (alpha) which determines the inclination of the virtual centreline of the groove (3) to the lengthwise rim (5) of the ski edge (1).

The curb of a ski, a snowboard or a skate

FIELD OF THE INVENTION [001] The subject of the invention is a curb of a ski, a snowboard or a skater, whose features increase the accuracy of ski guidance or reduce its sliding in turns, thereby increasing the speed and safety or accuracy of ski guidance.

Technical Problem [002] A technical problem solved by the invention is how to design such a ski edge, ski or skating rink that will significantly reduce skating in turns regardless of the type of sport utility provided and in particular regardless of the hardness of snow or even ice.

BACKGROUND OF THE INVENTION [003] As a rule, the metal edges incorporated into the skis and the ski boards are made with different cross-sections, which are unchanged throughout. For skates that are metal, the two edges are always the same.

[004] Increasing the adhesion to the curb is achieved by having the curb having a longitudinally extending groove and a longitudinal edge having a cross-sectional angle of less than 90 °, with this angle being variable. Such curb for skis and ski boards is known by SI 20009 (Stare Janez, Stare Luka).

[005] The disadvantage of the design of curbs with longitudinal grooves is that their performance is impaired by increasing the hardness of snow, and especially on ice. It is in this situation, however, that skiing or snowboarding is most necessary. Skaters also have the same need for controlled steering, especially in turns and jumps, especially when bouncing and jumping. The tonamen solution is known in GB 2186803 (Janez Jenko).

[006] A common feature of all known edges is that their construction increases the surface pressure of their edge on the substrate when the ski in a bend is positioned obliquely on the substrate. The result is a deeper screaming of the curb and thus the ski into the ground. The larger the surface of the base on which the ski, board or skate rests, gives more vegetation for good grip. Unfortunately, this property falls with the hardness of snow or ice. With increased snow or ice hardness, the need for a skier or skater to increase grip increases.

[007] Therefore, there is a need for a new curb design that will also be effective in hard snow and ice.

[008] Solution to a Technical Problem [008] The technical problem described is solved by the fact that the curb of a skiing board or skater is made on a lateral surface with grooves extending transversely to the longitudinal center line of the curb. These grooves are differently shaped and some embodiments will later be shown as embodiments. The characteristic feature of these grooves is that their edges or surfaces, in interaction, form blades by which the skipper cuts into a snow groove when pitching a ski or other props when cornering, thus increasing the lateral surface of the curb in snow or ice and with the stability of the ski, etc. in a turn. In other words, if the current curbs impress the ski, etc. in the snow or ice, the curb is carved according to the invention. This increases the gutter compared to the gutter created by the current edges. Consequently, the stability of the ski, etc. greater in turns than known edges.

[009] In more detail, the features of the invention will be explained by the description of embodiments and the accompanying drawing, in which FIG. 1 perspective view of the curb according to the invention.

[0010] The edge 1 of the ski A, snowboard or skater is made as any profile, preferably as an L-profile. In the case of a skater, curb 1 is substantially uniform with the skater core, which does not alter the invention. Otherwise, the profile of curb 1 is different depending on the anchorage of the curb to the core of the ski or snowboard, which is not the subject of the invention. The invention can be made on any edge profile 1.

PP / 37155.doc-IX / 09-Vr [0011] The lateral face 2 of edge 1 is made with grooves 3 extending transversely to the virtual longitudinal axis of edge 1. The grooves 3 may be of different cross-sections. It is essential that the grooves 3 form a lateral surface 2 of the edge 4, which together with the surface of the groove 3 and the lateral surface 2, form blades with cutting edges and surfaces as defined by the principle of the blade.

[0012] It follows from the foregoing that by varying the cross-section of the groove 3 and the angle Of, which determines the inclination of the center line of the groove 3 relative to the longitudinal edge 5 of edge 1. The angle Of Of is preferably less than 90 ° when measured in the direction toward the tail of the ski. . The edge 4 is thus tilted toward the tail of the ski. The cross-sectional shape of the groove 3 adds a definitive geometric shape to the blade formed by the groove cross-section 3 and the angle Of. Depending on the type of snow or ice and the type and method of skiing or skating, the geometric parameters listed are varied for best effect.

The groove section 3 may be semicircular, consisting of at least two flat surfaces, an irregularly arranged surface, and the like. The cross-sectional shape of the groove 3 determines the cutting edge 4 on the lateral surface 2, with the angle Of the cutting edge 6 on the sliding surface 7 of the ski or snowboard. Even on a skater made of one material, it is reasonable to make grooves according to the invention on its lateral surfaces only by knowing the above description of the invention.

[0014] Furthermore, the longitudinal arrangement of the grooves 3 on the curb is worth considering

1. In the basic embodiment, the grooves 3 are arranged in a uniform spacing over the entire length of the curb 1 or are concentrated in groups that are arbitrarily located along the length of the curb 1. The arrangement of the grooves 3 along the curb 1 and the size of the grooves 3 affect the degree of curb action by invention. It is expected that using different shapes and

PP / 37155.doc-IX / 09-Vr Curb Dimensions According to the Invention, Optimal Designs for Individual Types of Skiing as well as Snow or Ice Types Exposed. The described can only be optimized by the experiments and long-term use of both competitors and recreational athletes.

[0015J The operation of the groove with the grooves of the invention is significantly more efficient than any known curb. This results in faster winding, a significant reduction in slippage, and thus more accurate cornering. However, it is true that the curb according to the invention can cause severe cuts in accidents. Combat is also vulnerable to the harmful effects of stones or other materials that can be expected in snow or ice.

[0016] It is understood that one of skill in the art may, on the basis of knowledge of the description of the above invention, also design different embodiments, particularly in terms of industrial design, without circumventing the features of the invention as defined in the following claims.
