DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather skiing area having an openable roof on a slope.

[0002]

[Prior art and its problems] As a conventional ski resort,
BACKGROUND ART There are known natural snow skiing areas in mountainous areas, artificial snowy skiing areas built in mountainous areas, and indoor artificial skiing areas provided in urban areas.

[0003] Ski resorts with natural snow are the most common ski resorts, but cannot be slid during stormy weather, and skiers are forced to wait in lodgings. In addition, when the roof is hung on the slope of the ski slope, the slope does not function as a ski slope without snow.

[0004] Among mountainous areas, in places where the ability to attract customers is close to urban areas, even in places where the amount of snowfall is small, it is often the case that ski areas are opened by making artificial snow. Although artificial snow ski resorts in mountainous areas make up a small amount of snowfall with artificial snow, natural snow or artificial snow is washed away by rain if there is no roof on the slopes, because there is rainfall even in winter. Lose the function of ski resort. In addition, when a roof is laid on a ski resort, it is not possible to use the snowfall which is small in the first place. Therefore, in this kind of ski resort,
The gliding period is limited to the severe winter season, and the number of business days must be short.

[0005] Furthermore, as a recent boom, all-season covered ski resorts using artificial snow have been constructed even in urban areas.
You can only gliding in a closed room at all times, and it is almost impossible to enjoy the outdoor scenery.

[0006] In order to improve such disadvantages of the conventional ski resort, a ski resort provided in a mountainous area is provided with a detachable heat insulating tent that covers the top and sides of the ski resort and an artificial snow making machine. A year-round ski resort has also been proposed (Japanese Utility Model Laid-Open No. 62-202879). However, as is well known, the weather in mountainous areas tends to change suddenly, and it is necessary to open and close the roof quickly. In addition, strong measures against snow and strong winds are required for ski areas in mountainous areas.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an all-weather ski resort in which a roof can be opened or closed according to the weather conditions by installing an openable roof on a ski slope. Things.

[0008]

The all-weather ski area of the present invention has a movable roof laid horizontally on a guide rail laid along a slope and above a support structure standing up from the ground , A fixed roof capable of storing the movable roof is provided at an arbitrary position on the guide rail. In the all-weather ski resort of the present invention, it is preferable that a bellows-like film material is stretched on the movable roof. In addition, the fixed roof is erected at intervals,
It is preferable that a film material is suspended from the guide rail as the movable roof.

[0009]

The movable roof is used in a closed state when the ski resort is in rainy weather or other stormy weather, and is used in an open state in snowfall or fine weather.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the openable roof 10 installed at a ski resort in a mountain area, and FIG. 2 is a front view of the openable roof 10. In the first embodiment, fixed roofs 12, 12 are installed at upper and lower positions on the slope, that is, above and below the course, and a plurality of movable roofs 14, 14,... The size of each of the fixed roof 12 and the movable roof 14 can be freely determined according to the scale of the slope, both in width and length. The length in the course direction is adjusted by the number of movable roofs 14 installed.

The movable roof 14 is mounted on a pair of rails 20 laid in the vertical direction of the course via wheels (not shown).
It is laid so as to cover the slope. Movable roof 14
On the rail 20 laid on the upper part of the support structure 22,
It is towed by a wire rope and winch and moved. Alternatively, the movable roof 14 can be driven by a motor-driven cart. On the other hand, fixed roof 1
2 is fixedly installed on the support structure 22.

FIG. 3 is a vertical sectional side view taken along the line III-III of FIG.
The positions where the plurality of movable roofs 14 are accommodated are indicated by broken lines.

FIG. 4 shows a fixed roof 12 and a movable roof 14.
3 is an enlarged view of a roof part of the present invention. These roof parts are configured by using a cable 17 and a membrane material 18 in a frame formed by a steel truss 16. As the structure of the roof portion, various other types can be adopted, but a light-weight structure that has a large resistance to a snow load and is preferable.

As described above, normally, a plurality of movable roofs 14 are provided in the course direction. However, the fixed roof 12 is also provided at any one of the upper, lower, and intermediate portions of the course, and all the movable roofs 14 are provided as one of them. It can also be stored under a fixed roof 12 at a location. It is also possible to store the movable roof 14 not in the lower part of the fixed roof 12 but in the upper part thereof, or to store the movable roof 14 several times above and below the fixed roof 12.

The closed state of the openable roof 10 shown in FIG. 1 and FIG. 2 is a form used when no snowfall, rainfall, snowstorm, or when it is desired to prevent thaw due to outside temperature. From this state, the movable roof 14 is moved up and down (in the direction of the arrows in FIGS. 1 and 2) on the slope, and the fixed roof 1 is moved.
If it is accommodated in the lower interior of 2 and 12, the openable roof 10 is opened. This open state is a form used during snowfall, fine weather, and the like.

FIG. 5 shows a second embodiment of the present invention. FIG. 1A is a perspective view of the opening and closing roof 10, and FIG. 1B is a partial front view of the opening and closing roof 10 taken along a central portion thereof.
In the second embodiment, a movable roof 14 is erected on a pair of rails 20, 20 laid on the upper part of a support structure 22, and the movable roof 14 is framed by an arched steel truss 16, and the movable roof 14 is framed thereon. A bellows-like film material 18a is stretched.

In this embodiment, by moving the carriage 24 on the rail 20 in the direction of the arrow, the movable roof 14 moves and the film material 18a expands and contracts, so that the opening and closing roof 10 opens and closes.

FIG. 6 shows a third embodiment of the present invention. FIG. 1A is a perspective view of the opening and closing roof 10, and FIG. 1B is a partial front view of a central portion of the opening and closing roof 10, which is longitudinally cut.
In the third embodiment, a steel truss 16 is laid horizontally at appropriate intervals in the course direction, and a fixed roof 12 is formed at this portion. A plurality of cables or steel members 20a are stretched between the steel trusses 16, 16 as guide rails in a straight line in the vertical direction of the course, and an elastic film material 18a is suspended from the cables or steel members 20a. . Therefore, the opening and closing roof 10 can be opened and closed by drawing or extending the film material 18a.

[0019]

The all-weather ski area according to the present invention can quickly and smoothly open and close the roof by horizontal movement and expansion and contraction. In addition, the open / close roof is lightweight as a whole, can be manufactured firmly, and has sufficient resistance to snow load. Therefore, the present invention can be applied to various types of ski areas to obtain the following remarkable effects.

(1) When applied to a mountainous ski resort with a lot of snow, it is possible to provide a comfortable indoor skiing area by opening the roof in good weather and making it a natural skiing area and closing the roof in stormy weather. .

(2) When the present invention is applied to a mountainous skiing area near a city with little snow, the roof is opened during snowfall to allow snow to fall on the slope, while the roof is closed during rainfall or rough weather, and the snow on the slope is washed away. It can provide a comfortable environment for skiers. Also,
In summer, the roof can be closed and air-conditioned to create an all-season ski area.

(3) When applied to an artificial ski resort in an urban area, the roof can be opened in good weather to provide an open ski resort under the open air.
