Tennis net with posts

摘要

In tennis, many points are scored with a hard service. A tall player hits with a hard service over a greater field before the out line than a shorter player and hits the ball to land inside the court much more easily. With a shorter player the net has to be hung that much lower so that he or she can hit over a field ending before the out line. To this end, net posts are used which can be pushed outwards and secured with pins in different positions which conform to different body heights.
