BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial ski resort capable of gliding in a snowless state.

[0002]

2. Description of the Related Art Conventionally, regions with little snow or regions with no snowfall,
In ski seasons during off-season, in order to make it possible to run even in the absence of snow, a synthetic artificial skim made of resin is laid on the planned sliding surface such as the ground surface, and normal skiing is performed on the surface of this artificial skimat. There are things that can be slid on a board.

[0003] However, the artificial schemat made of this resin has a drawback that when it is attempted to increase the sliding speed, the viscosity becomes high and the frictional force with the ski increases, so that the sliding cannot be performed with a sense of speed. It was Therefore, it is known that a sprinkler such as an impact type sprinkler is installed in an artificial ski resort to sprinkle water from the upper surface of a resin mat, and water is attached to the surface of the mat to reduce friction between the mat and skis. Has been.

In another different conventional example, as in the invention described in Japanese Patent Application Laid-Open No. 4-80406, a plurality of sliding surface plate members adhered in a scale shape on a mat are provided, and the mat and the sliding surface are provided. It is known that water is blown out from a water ejection port provided between the surface material and a surface material to form a water curtain on the surface of the sliding surface plate material.

[0005]

[Problems to be Solved by the Invention] However, an artificial ski device in which a water sprinkler such as an impact type sprinkler is installed on an artificial ski resort and water is sprinkled from the upper surface of a resin mat, is placed at a position higher than the surface of the mat. Install a sprinkler. Therefore, sprinklers were installed on both sides of the course and water was sprinkled from above in order to avoid collisions during the run.

Therefore, since it is necessary to sprinkle water from a distance far from the water sprinkler, it is necessary to sprinkle water from a high position using a large water sprinkler, which requires a large amount of water, resulting in poor economic efficiency. . In addition, the diameter of the water droplets sprayed by a large water sprayer is large, the adhesion to the mat is poor, and the effect of improving the gliding property is low. In addition, the watering from a high position wets the body of the skier, which made it inconvenient because he could not slide while watering.

Further, as in the invention described in Japanese Patent Application Laid-Open No. 4-80406, water is blown out from between the mat and a plurality of plate materials for sliding surfaces, which are laminated and attached in a scale shape on the mat, and the sliding surface is used. Those who tried to form a water curtain on the surface of the plate material cannot form the water curtain without using a large amount of water. That is, since the surface tension acts on the surface of the sliding surface plate material and the sliding plate material is inclined, water flows in a streak shape and cannot form a water curtain. Also, if a large amount of water is used, a water curtain can be formed, but it becomes difficult to run and becomes extremely uneconomical.

The present invention is intended to solve the above-mentioned problems, and is an artificial body in which a plurality of rod-shaped projections which come into contact with a ski are projected on the surface and an opening for spraying water is provided in the central portion. While spraying a small amount of water on the surface of the schemat, it improves the water contact with the mat, improves the gliding speed, and enables favorable gliding. In addition, watering will be performed from a lower position with respect to the artificial schemat to enable uninterrupted gliding even during watering.

[0009]

In order to solve the above-mentioned problems, the present invention has a plurality of rod-shaped projections, which come into contact with a ski, projected on the surface and an opening for spraying water in the central portion. The artificial schemat is laid on the planned sliding surface, the water supply pipe is arranged on the foundation of the planned sliding surface, the surface of the water supply pipe is covered with the artificial schemat, and the spray type sprinkling nozzle is provided for each of the multiple artificial schemats. Is formed on the water supply pipe, and this spray type sprinkling nozzle is arranged so as to face the opening without projecting on the surface of the artificial schemat, and water is sprayed on the surface of the artificial schemat through the opening to form a stick shape. It is configured such that fine water droplets can be attached to the plurality of projections of.

[0010]

Since the present invention is constructed as described above, water is passed from the water supply pipe to the spray nozzle in order to increase the gliding speed and enable a preferable gliding. By this water flow, mist-like water is sprayed on the surface of the mat from the spray-type sprinkling nozzle that is arranged facing the opening of the artificial schemat,
Fine water droplets adhere to the surface of the artificial schemat, which has a plurality of rod-shaped projections that come into contact with the ski.
Fine water droplets are present between the skier's ski and the artificial schemat, and the frictional force between the ski and the schemat during sliding can be reduced. Therefore, it is possible to glide at high speed without increasing the viscosity of the artificial schemat.

Further, the spraying type water sprinkling nozzle is provided so as to face the opening of the artificial schemat, and since the nozzle does not project on the surface, it is possible to safely slide without obstructing the sliding of the skier. To do. Further, since it can be installed in the course, it is not necessary to install a large water sprinkler to spray water having a large particle size to a distance far from the nozzle, and the amount of water sprayed can be reduced.

Further, since the water droplets sprayed from the spray-type sprinkler nozzle have a smaller diameter than the water droplets ejected from a large water sprinkler, they adhere well to the surface of the artificial schemat and the effect of improving the gliding property is remarkable.

Further, since a small amount of spray is sufficient from a low position in the course and a large amount of water is not sprinkled from a high position, even if gliding in the water, it is possible to wet the entire body of the runner by just wet the feet. In addition, it enables gliding without interruption during sprinkling, and is economical because the amount of water used is small.
