Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an artificial ski slope.

[0002]

[Prior art]

 Conventionally, in artificial ski slopes, for example, at 0 ° C or below, artificial snow produced by spraying high-pressure water into the atmosphere is used to produce slopes, or instead of artificial snow, natural snow is transported. Then, the method of installing it on the slope was adopted.

[0003]

[Problems to be solved by the device]

 However, such an artificial ski slope has a very expensive device for manufacturing the artificial snow, requires a large amount of energy, and transports natural snow is also very expensive and troublesome. It is a thing. Further, there has been a problem that a great burden is imposed economically and technically to maintain and manage the manufactured artificial snow and the transported natural snow.

The present invention has been made to solve such a problem, and can be manufactured easily and inexpensively, and can maintain good artificial snow in a stable state for a long time. The challenge is to provide a ski slope.

[0005]

[Means for Solving the Problems]

 The present invention has been made as a solution to such a problem, and means for solving the problem are as follows: a base 2 having a large number of cooling pipes 3 on a heat insulating material layer 1, and a base 2 on the base 2. The structure is composed of the ice lump layer 4 provided and an artificial snow layer 5 formed by crushing the surface of the ice lump layer 4.

[0006]

In the artificial ski slope with the above-described structure, the ice mass layer is formed on the upper portion of the base having the cooling means, so that the ice mass layer is effectively cooled and maintained without melting for a long time. .

Further, since the artificial snow layer is formed on the ice block layer, the artificial snow layer is also maintained at a low temperature, and the snow condition can be kept in good condition.

In addition, it is possible to provide an artificial ski slope which is cheaper in manufacturing cost and maintenance cost than the conventional artificial ski slope and can maintain a slope condition for a long time.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a foamed polyethylene heat insulating material, which is arranged between a slope ground 8 and a waterproof sheet 7. As shown in FIG. 2, reference numeral 2 denotes a synthetic resin base consisting of a panel 2a and a large number of cooling pipes 3 arranged in parallel with the panel 2a, which is installed on the heat insulating material 1 through a waterproof sheet 7. . Dry ice is incorporated in the cooling pipe 3 of the base 2 as a cooling means.

Reference numeral 4 denotes an ice lump layer, which is formed on the upper portion of the base 2, and an artificial snow layer 5 formed by crushing the ice lump layer 4 is formed on the upper portion thereof.

When an artificial ski slope with the above structure is manufactured indoors, for example, the room is kept at a constant temperature and humidity, ice blocks are arranged on the base 2, and water is poured from above to freeze the ice mass. By doing so, it is possible to easily produce an ice mass layer having a certain thickness.

Next, an artificial snow layer 5 made of free-flowing artificial snow can be easily formed by crushing the upper layer portion of the thick ice block layer 4 thus manufactured by a machine or the like to a certain thickness. .

Furthermore, since a large number of cooling pipes 3 provided on the base 2 contain dry ice, the vaporized cold air passes through the cooling pipes 3 and the ice block layer 4 is formed from the surface of the cooling pipes 3. Cool efficiently. Therefore, the ice mass layer 4 is maintained without melting for a long time. Therefore, the artificial snow layer 5 located above the ice block layer 4 is also maintained at a low temperature for a long time.

If the artificial snow layer 5 melts and the condition deteriorates as it is used, the artificial snow layer 5 is formed by crushing the upper layer portion of the ice block layer 4, By crushing the upper layer portion of the ice block layer 4 again, the artificial snow layer 5 can be easily regenerated. Therefore, the slope can be repaired in a short time, and it is easy to maintain the slope.

Although foamed polyethylene or the like is used as the heat insulating material layer 1 in the above embodiment, the material of the heat insulating material is not limited to this. The thickness of the heat insulating material layer 1 is designed according to the slope of the artificial ski slope.

Further, the material of the substrate 2 is not limited to the synthetic resin of the above embodiment.

Further, in the above-mentioned embodiment, the ice lump layer 4 was manufactured by pouring water from above the ice lump and freezing it. However, the manufacturing method of the ice lump layer 4 is not limited to this, and the upper layer part is essential. It is only necessary to provide an artificial snow layer 5 at the bottom of the artificial snow layer 5 and to form an ice layer enough to form the ice block layer 4 with a constant thickness in the lower layer.

The thickness and hardness of the artificial snow layer 5 and the ice block layer 4 vary depending on the grade for advanced skiers and beginners, so it is preferable to design according to the ski slope. Yes.

Although the above embodiments have been described in the case of an indoor artificial ski slope, the present invention is not limited to this and can be applied to an outdoor artificial ski slope.

[0021]

[Effect of device]

 As described above, since the present invention has a structure in which the ice mass layer is formed on the base provided with the cooling means, the ice mass layer can be maintained for a long time by the cooling means, and thus the ice mass layer is formed in the upper layer part. The artificial snow layer is also maintained at a low temperature, which has the effect of maintaining the snow condition for a long time.

In addition, the artificial snow can be easily regenerated by crushing the ice block layer, which has an effect that the artificial ski slope can be easily repaired and maintained economically.

Further, since the cooling means is dry ice, it is easy to obtain and inexpensive, and the cooling means can be easily handled.

In addition, because of the structure of the artificial ski slope according to the present invention, it is possible to provide an artificial ski slope that is easier to set up and maintain and is cheaper than the conventional artificial ski slope.
