DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat for a snow slope on a ski slope.

[0002]

2. Description of the Related Art In most cases, snow slopes are formed directly on the ground at outdoor ski slopes, but snow mats are sometimes laid to increase the adhesive strength between the slopes and the snow floors.

[0003] In an indoor artificial skiing area, since a snowy floor is formed on a slab having an inclined structure, the existence of a snow mat as described above is indispensable so that snow does not slip down.

[0004] Conventional snow mats are of a net shape or of an artificial turf type as disclosed in Japanese Patent Application Laid-Open No. 4-52307-52310, and have an adhesive force (prevention of avalanche) with snow forming a snow floor. It is for the purpose of strengthening only.

[0005]

On a slope having a steep slope and a complicated slope, when a large number of skiers skate in a concentrated manner, the snowy floor is shaved, the snowy floor disappears, and at the same time, a large snow bump is generated. This is a dangerous slope, especially for beginner skiers.

[0006] Even if the snow mat is provided, the snow floor is not greatly reduced.

[0007] The object of the present invention is to solve the disadvantages of the prior art and to provide an adhesive force (prevention of avalanche) with the snowy floor, as well as to strengthen the snowy floor and make the snowy floor strong. It is an object of the present invention to provide a ski slope slope snow mat that can be maintained as a stable and safe slope.

[0008]

According to the present invention, in order to achieve the above object, a base mat surface is provided with holes having openings with reduced diameters on the upper surface at appropriate intervals to form a needle-like fiber having an enormous root portion. The bulging root is fitted into the hole, needle-like fibers having different lengths are arranged side by side, and implanted at an appropriate density on the base mat surface. The gist of the invention is to have a beard.

[0009]

According to the first aspect of the present invention, since the needle-shaped fibers having different lengths are arranged side by side, the density of the fibers increases toward the bottom, so that snow hardly flows. Become. In addition, the length of the fibers in the sliding direction can be reduced to block the flow of snow. Further, when the snowy floor is shaved, the tip of the fiber appears, and the thickness of the snowy floor can be checked by the appearing fiber. In particular, if the fiber colors are different, it is possible to determine at a glance how much the snow floor has been cut.

[0010] In addition, since the enormous root portion formed in the needle-like fiber is fitted into the hole of the reduced diameter opening provided at an appropriate interval on the base mat surface, the fiber is implanted in the base mat. A simple and robust structure,
The snow floor becomes stronger.

According to the second aspect of the present invention, the provision of the fine fiber whiskers increases the adhesion of the fibers to snow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. 1 is a longitudinal sectional side view showing an embodiment of a snow slope mat of a ski slope according to the present invention, FIG. 2 is a longitudinal sectional side view of a main part of the same, and FIG. 3 is an enlarged view of a fiber tip.

This embodiment is a case of an indoor artificial ski resort. In FIG. 1, reference numeral 1 denotes a structural slab such as concrete. A heat insulating layer 2 is formed on the slab 1 and a waterproof layer 3 is further provided thereon.

The mat 4 of the present invention is laid on the waterproof layer 3, and the mat 4 is a base mat 5
The needle-like fibers 6a, 6b, 6c are implanted at an appropriate density on the surface so that fibers having different lengths are juxtaposed.

The base mat 5 is made of polyethylene resin such as linear low density polyethylene and has a thickness of 30 m.
The holes 7 having a diameter of about m and having an opening 7a with a reduced diameter on the upper surface were provided at appropriate intervals (30 mm to 50 mm), and a drain hole 8 having a diameter of about 5φ was formed between the holes 7.

The needle-like fibers 6a, 6b and 6c are made of polyethylene as a core material, and have sharp but sharp ends. And the diameter of the bottom is about 5φ, and the enormous root part 9 with a diameter larger than this diameter is provided.

The length of the longest fiber 6a among the needle-like fibers 6a, 6b, 6c is 300 mm to 4 mm.
About 00mm, fiber 6b is 250mm-350m
m, and the fiber 6c is about 200 mm to 300 mm. Further, these needle-like fibers 6a, 6b,
In FIG. 6c, as shown in FIG. 3, a high-strength polyester-based fine fiber whiskers 10 were provided on the outer periphery. The fibers 6a,
The colors of 6b and 6c may be different from each other.

The fibers 6a, 6b, and 6c are fitted into the holes 7 and fixed with an adhesive, so that the fibers 6a, 6b, and 6c project upward from the openings 7a above the roots 9 and are planted on the base mat 5. A lining 11 of nylon tarpaulin packing is attached to the bottom surface of the base mat 5.

Snow is deposited on the mat 4 to form a snow floor, and the fibers 6a, 6b and 6c have a softness which does not hinder the skier's sliding even when the fibers 6a, 6b and 6c are exposed on the slope surface. It has durability so as not to be cut or worn by sliding (eg, edging). Furthermore, the beard 10 increases the adhesion of snow.

[0020]

As described above, the snow slope mat of the ski slope according to the present invention becomes denser toward the bottom.
The bottom has a stiffer (slower) snow floor at the bottom, and the fiber height is different in the sliding direction, so the snow flow can be blocked and maintained as a stable and safe slope.

As described above, since the snowy floor is thinner than the natural snowy floor and the stiffness becomes stronger, the floor load can be reduced at the indoor artificial ski resort, and there are advantages in terms of structural planning and cost. .

Further, since the height of the fiber is different, it is possible to manage the thickness of the snow floor by checking the fiber that appears when the snow floor is shaved.
