Description

[Detailed description of the invention] (Industrial application field) The present invention relates to tennis courts.

(Prior Art) Conventionally, the following types of tennis courts are known. In other words, first of all, An Two Power Sea) (o
n-tou-cas-court), and this coat is said to be an all-weather coat. Next, clay
This court is called a red clay court in Japan. Also known as Lawn Court or Glass Fist Sea.
(This is a grass court, and this court has a grass seat.

Other courts include the indoor Itabaritan court.

(Problems to be solved by the invention) The all-weather court has the advantage of being able to be played at any time regardless of the weather, but the disadvantage is that it is not suitable for players of all ages and girls, as the ball is fast and the feet are prone to flrl. Compared to all-weather courts, clay courts have the advantage that the ball is not fast and there is less fatigue on the feet, but clay courts are affected by the weather, and if the court is poorly maintained, it bounces irregularly and requires maintenance. It's not easy.The advantage of a grass court is that the tennis ball spins?If you receive the tennis ball obediently, the ball won't break, your feet won't get tired, and your eyes are comfortable. etc., maintenance is not easy.

The G1 board has the disadvantage that the ball bounces quickly.

Comparing the pros and cons of each of the above courts from a player's perspective, we find that grass courts are the best, and that prestigious world tennis tournaments (such as the All England Championships) are held on grass courts. There are oysters.

However, because of the problems mentioned above, grass courts have not been widely used until now, even though they are promising for playing. In addition, it is impossible to play on any of the courts (except the indoor court with wooden boards) in Situation F when it is raining, and it is difficult to grow grass because it is impossible to supply sunlight indoors. However, even outdoors, in Japan's climate, it has the problem of withering in the winter.

(Closed 1 member!, 0 moves for 3 to go to t ~ ρ) The present invention is a natural grass tennis court, which is constructed inside an air membrane structure building equipped with an air conditioning control device. It is. The grass on the court grows throughout the year thanks to the sunlight that passes through the membrane roof and enters the room, along with the optimum temperature and humidity, such as the climate of Scotland, and its maintenance is maintained by constant indoor air conditioning. This is done using management.

(Ability level is low) Is the following an example of the present invention? The explanation will be based on the drawings.

The tennis court 1 is a natural grass court installed inside an air membrane structure building 20 equipped with an air conditioning control device (not shown).A white line 4t is drawn on the grass 3 of this court, and a net 5 is placed in the center of the court. It is arranged.

Air membrane structure building 2 is an elliptical dome with an area of approximately 840 square meters (frontage 34 m, depth 28 m) and a height of 12 m at its highest point, with two indoor courts. The ball is wide enough to be installed and has a height that does not hinder the movement of the ball. This building has a living beam 22g at the upper end of the outer peripheral wall 21,
A cable 23 in two directions is strung across the roof surface, both ends of the couple are fixed with a ring beam, and a translucent membrane material 24 is stretched between the cables to form a membrane roof. Air is introduced into the room by a blower, and the air pressure in the room is increased. The membrane roof is raised 25 mm above the atmosphere in terms of water column, and the membrane roof is supported by the pressure difference between indoor and outdoor air. In addition, during strong winds, the pressure difference is set to about vi-3 times, and the rigidity of the vesicle membrane ensures safety against external forces. The membrane roof is provided with a fan 25 for exhaust. The membrane material 24 is a glass fiber membrane material coated with Teflon (registered trademark), and has a translucency of about 10% to 20%, allowing the grass 3 of court 1 to grow under natural lighting. Due to daylight, no lighting is required during the day, and the indoor tF3A space has a bright and open feel, allowing players to play with the same feeling as playing outdoors.

The air conditioning inside building 2 is done through an air conditioner, and the air conditioner is controlled by pressurizing the room. In addition to controlling the pressurizing devices such as blowers, the system is also controlled by an automatic control device installed in the management room. Therefore, the maintenance of the turf 3 is performed through an automatic control device that maintains the indoor environment of the building 20 at the optimum temperature and humidity for the turf 3 and at a constant constant level at all times.

In addition, even in cold regions with heavy snowfall, the membrane roof is completely double-layered, and warm air flows through it. Snow melting can be carried out with high efficiency by feeding the snow, and even in hot summers and high temperature regions, the air space between the membranes acts as a heat insulator, reducing cooling costs. Therefore, it is completely unaffected by wind, rain, and lightning, so it can be used in all regions from warm regions to cold regions, and of course, it can be played indoors throughout the year.

(Effects of the Invention) As explained above, according to the present invention, sunlight of an air membrane structure building can be absorbed by the membrane roof. Natural light can pass through, and indoor air conditioning can be maintained at a constant level at all times, making it easy to maintain and manage the growth and maintenance of the turf throughout the year. The ball doesn't cut or bounce fast, so anyone can play on it regardless of gender or age, and it retains the characteristics of a grass court, which reduces knee fatigue and is easy on the eyes. Furthermore, the facility according to the present invention can be installed in all areas from the north to the south as mentioned above, and the facility's operating rate is approximately 20% per year. By being able to play through it, it has the effect of increasing the overall score.
