Abstract

PROBLEM TO BE SOLVED: To facilitate laying and installing and to make speed faster and turning easier by laying the net fabric formed to a nodular form by using synthetic fibers on a slope surface. SOLUTION: The net fabric 1 is formed by joining one or plural pieces of yarn of a mono type of polyethylene, polyester, polypropylene or vinylon, etc., as a net leg 2. The net fabric 1 is thereby made into a nodular net having node parts 3. Such net fabric 1 is fixed and laid to the ground surface of the slope 4 of a skiing ground by using anchor-like fixtures 6 connecting ropes 5. As a result, the movement and peel thereof are prevented. While the meshes of the net fabric 1 may be any of square, rectangular, rhombic and other shapes, the mesh opening sizes are preferably the sizes to prevent the width of ski boards, etc., or the front ends of the ski boards, etc., from being nabbed by the meshes at the time of gliding, approximately about <=100mm. As a result, the friction resistance is made lower, the speed higher and the turning easier.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reduces the frictional resistance of skis, snowboards, sledges, and other snow skiing tools, thereby increasing speed and making small turns. It relates to a slope such as skiing.

[0002]

2. Description of the Related Art Since skiing equipment such as skis, snowboards and sleds are used on snow in principle, it is assumed that snow is present. However, since snow outside can not be expected except in winter, in other seasons, as described above, in order to be able to practice and play with skiing and other skiing equipment as described above, an artificial grass-like sheet It is also laid on the slope surface.

As is already known, this artificial turf-like sheet is formed of a synthetic resin or other material, and its surface is formed in a dense brush shape.

[0004]

As a result, the contact area of the ski or the like with the sliding surface becomes large (surface contact), and as a result, the frictional resistance becomes large and it is difficult to increase the speed.

The brush-like portion of the artificial turf-like sheet is relatively flexible and has a high frictional resistance.
It was pointed out that it was difficult to make small turns. Therefore, the feeling of sliding on real snow cannot be obtained,
I didn't want it to be good.

Further, the artificial turf-like sheet has rigidity as a whole and has a large area. Therefore, it is difficult to handle the artificial turf-like sheet when installing it on the slope surface, and the laying work is not easy. In other words, construction costs increased.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a ski slope such as a ski according to the present invention (Claim 1) is provided with a knotted net formed by using synthetic fibers.
It was laid on the slope surface.

According to a second aspect of the present invention, in order to solve the above-mentioned problems, the mesh is formed of a monotype yarn of polyethylene, polyester, polypropylene or vinylon. .

[0009]

According to the first aspect of the present invention, there is provided a ski and other ski slope according to the present invention.
At the time of the run, it comes into contact with the net legs of the net, especially the nodule, so it slides by contacting in a so-called point contact state,
Therefore, the frictional resistance is significantly reduced, the speed can be increased, and a small turn can be made.

According to the second aspect of the present invention, in addition to the above-described effects, the friction resistance can be reduced and the speed at the time of skiing can be increased.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a ski slope such as a ski according to the present invention will be described with reference to the drawings.
For example, a net is formed by using one or a plurality of mono-type yarns such as polyethylene, polyester, polypropylene, and vinylon, and combining them to form a net leg 2. That is, it is formed into a knotted net.

The mesh 1 used here may have any mesh shape such as a square, a rectangle or a rhombus, but the size of the mesh is the width of the ski or the like when skiing. In consideration of preventing the tip (top) from being caught on the mesh, it is preferably about 100 mm or less.

The net 1 formed as described above is laid on the surface of a ski slope 4 at a ski resort. In this case, in order to prevent the laid net 1 from accidentally moving or peeling during skiing or the like. Next, as shown in FIG. 3, an anchor-shaped fixture 6 to which the rope 5 is connected is stabbed in the ground, and the rope 5 is used to connect and fix to the net 1 using the rope 5. In addition, the fixing is performed at positions interspersed with the periphery of the mesh 1 and other portions. However, when the distance between the fixing positions is long, in order to prevent separation due to wind pressure, the mesh is fixed as described above, The periphery of the ground 1 may be covered with soil. Even if it is covered with soil in this way, there is no particular hindrance since that portion is not a position that affects the sliding of a ski or the like. Note that skiing with a ski or the like may be performed in the same manner as skiing on snow.

[0014]

As described above, according to the ski slope of the present invention (claim 1), the knotted net formed by using synthetic fibers is laid on the slope surface. The sliding surface of a ski or the like comes into contact with the net legs, particularly the nodules, at the time of the sliding, and as a result, it can contact and slide in a so-called point contact state, so that the frictional resistance is significantly reduced. The effect is that speed can be increased, small turns can be achieved, and the netting is flexible, so that it can be adapted to the terrain of the slope and is easy to handle when laying, and can be provided at low cost. Having.

According to the ski slope of the present invention (claim 2), the net is formed of a monotype yarn of polyethylene, polyester, polypropylene or vinylon. This has the effect of reducing frictional resistance and speeding up the skiing.
