Wheelchair tennis competition Garden
According to the rules of tennis rules published by the International Tennis Federation, the air volume of a standardized tennis garden shall not be less than 36.58 meters (length) × 18.29m (width), which is also the net size of a standardized tennis court with fence net around or interior wall built indoors. In this area, the standard size of the effective doubles garden is 23.77 meters (length) × 10.97m (width). There shall be space behind each end line and sideline. The end line shall not be less than 6.40m and the sideline shall be more than 3.66M. Install net posts on the court with an interval of 12.80 meters between the two net posts. The top of the net column is 1.07M away from the ground, and the top edge of the net is 0.914m away from the ground. In case of two or more adjacent parallel tennis courts, the spacing between the sidelines of adjacent courts shall not be less than 7.32 meters. If it is an indoor tennis court, the clear height above the end line 6.40 meters shall not be less than 6.40 meters, and the clear height of the indoor roof above the tennis net shall not be less than 11.50 meters.
The first question to consider for outdoor tennis courts:
(1) Sunshine problem: in order to avoid sunlight, the direction of outdoor tennis courts is mostly north-south. If there are buildings around, it can be discussed separately.
(2) Rainfall and drainage: in order to ensure the normal use of the garden in the shortest time, according to the rules of the international network union, the apron slope of the outdoor garden is transverse, and the slope is no more than 8 ‰. The height of the fence around the outdoor tennis garden is mostly between 4 ~ 6m, which can also be increased or decreased according to the surrounding conditions of the court and the height of buildings. For tennis courts where lighting must be installed, except for indoor roof lamps, lamps shall not be set over outdoor courts and on both sides of the end line. Outdoor court lamps shall be set at the fence nets on both sides, more than 7.60 meters high from the air, and the lights shall shine evenly from both sides of the court to the garden. The uniform brightness of the lighting of each tennis court should be more than 600 lux. The Paralympic Games require more than 1500 lux.
