Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow storage bag seat which can be diverted to a grass ski mat used for opening a ski area without being affected by a natural lack of snowfall or an outside temperature.

[0002]

2. Description of the Related Art In recent years, there are many cases in which the establishment of a ski resort is hindered due to the effects of a shortage of natural snow and warm winter. Therefore, recently, artificial snowfall devices have been actively introduced. The artificial snowfall devices are roughly classified into fan type and gun type. The snowmaking means of these devices is 0
In the atmosphere below ℃, high pressure water is released by utilizing adiabatic expansion of compressed air, or cold ice is used to make fine ice.

In addition, recently, in order to open a ski resort regardless of the outside temperature, a method of making ice in advance with a refrigerator and finely crushing it and spraying it on a slope is also widely used. An essential requirement in this case is to store the produced fine ice (artificial snow) at low cost for a certain period. For this reason, conventionally, it has been stored in an underground tank provided at a ski resort or piled on a slope and covered with a sheet or the like.

[0004]

However, the conventional artificial snow storage method, for example, the method using an underground tank attached to a ski resort has a limited capacity. Further, there is a drawback that auxiliary equipment is required even when taking out. Furthermore, the method of storing piled sheets on the slopes and covering them with sheets, etc. results in the costly artificial snow melting during daytime when the temperature is high or due to wind and rain, and it requires a lot of time and effort to maintain the slopes. There was a problem.

The present invention provides, as an inexpensive storage means for artificial snow and the like, which solves the above-mentioned drawbacks and problems, a cylindrical snow storage bag made of a sheet that can be easily assembled, and the bag is opened on the slope. We provide a snow storage bag seat that can be formed by simply unfolding it and can be used as a glass ski mat during the off-season, which not only reduces the size of the snowmaking device but also makes it an artificial ski resort. It was developed with the aim of promoting the rationalization of construction as

[0006]

Therefore, in order to achieve the above-mentioned object, it is configured to store by the following means. First, right and left edges of a quadrilateral sheet were joined together and rolled into a cylindrical shape, and lid plates were detachably attached to both ends of the cylindrical sheet to form a cylindrical snow bag.

The sheet is made of a heat insulating material, and artificial turf-like protrusions are planted on the surface of the sheet.
The back surface was coated with a light reflecting film.

Further, in the above-mentioned sheet, the projection pieces are provided on the surface,
A plurality of sheets were laid on the upper surface of the slope, and adjacent sheets were integrally bonded to each other and fixed to the slope surface.

The sheet is characterized in that it can be used as a glass schemat.

[0010]

When the snow storage bag sheet which can be diverted to the glass schemat configured as described above is used, the air layer is formed by the projection pieces planted on the surface of the sheet, so that the heat insulating effect is further enhanced. , Effectively prevent snow melting due to rain and wind or outside air.

Further, since the snow-storing bag sheet is laid on the slope, the required amount of snow can be secured on the slope easily and quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific example according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is an embodiment showing a snow storage bag formed by the snow storage bag sheet of the present invention. (I)
[Fig. 3] is a schematic view showing a state of being laid on a slope. (B) is
It is explanatory drawing which shows the filling method of artificial snow.

As shown in (a) and (b) of FIG.
Insulation sheet 10 with adjacent ropes connected by connecting ropes 14
Are laid on the upper surface 13 of the slope at regular intervals (3 m in this case), and the rope 11 is passed through the fastening holes (with ring fittings) 15 provided on the left and right edges of the heat insulating sheet 10 to be rolled into a cylindrical shape. A lid 12 (the diameter of the lid 12 in this case is 1 m) is attached to both ends, and artificial snow 16 is filled into the interior via a transport pipe 17 to form a snow storage bag A.

In the case of the embodiment shown in FIG. 1, the distance between the heat insulating sheets 10 is 3 m, and the diameter of the lid 12 in the snow storage bag A is 1 m. This is an example in which the snow accumulation back A is unrolled, unfolded and connected by the connecting rope 14, and the snow accumulation amount on the slope upper surface 13 is 25 cm when the cylindrical artificial snow 16 is smoothed by a snow plow or the like. .

FIG. 2 is a schematic perspective view showing the structure of the snow storage bag seat of the present invention. In this description, the case of FIG. 1 will be described. First, in this snow storage bag sheet, the protrusions 18 were planted on the side of the heat insulating sheet 10 that is filled with snow, that is, the front side, and the light reflection film 19 was coated on the outside air side when rolled, that is, the back side. The protrusions 18 improve snow adhesion and form an air layer with the snow. This, together with the light reflection film 19, results in enhancing the heat insulating effect.

Further, since the above-mentioned snow storage back seat can be diverted as a glass schemat in the off season, there is a great merit.

[0017]

Since the present invention is configured as described above, it has the following effects. ， Since the snow storage bag sheet according to the present invention is a slope laying type, the storage location itself is the slope itself. As a result, the time and labor required for snow transportation and the like have been greatly reduced, and the required amount of snow has been secured easily and quickly. ， Snow can be set only by deploying the snow storage bag installed on the slope, so the maintenance time to level the snow with a snow plow etc. has been greatly shortened. The snow storage bag according to the present invention enables stable and stable storage of snow at low cost and enables downsizing of a snow making device, thereby promoting rationalization of construction of an artificial ski resort. ， Since the snow storage bag seat according to the present invention is a glass ski convertible mat, it can be enjoyed in the off season and has high utility value.
