Description

  The present invention relates to table tennis equipment, and more particularly to an improved table tennis equipment with improved sizes of court tables, nets, rackets, and balls.

Table tennis is a type of ball game, and since ancient times, it has been loved by many people, regardless of whether it is professional, amateur, or young and old. It is popular in Japan and all over the world.
In such conventional table tennis, from the side as a competition, the length, width, height, net height, ball, racket, etc. of the equipment to be used are all standardized. The length is determined to be 2740 mm, the width is 1525 mm, the height is 760 mm, the net height is 152.5 mm, and the ball is 40 mm or 44 mm.

  Among the standardized tool sizes, the height of the net is particularly related to the ball speed. That is, when the player hits the ball during the rally, the ball speed tends to gradually increase as the net height is lower. This means that the harder you hit the ball with the racket, the higher the probability that the ball will be caught on the net, but conversely, if the net is low, the probability that the ball will cross the net and enter the enemy's court increases, so the ball with the racket The ball speed can be increased as a result.

  Therefore, according to the net height of 152.5mm already standardized as conventional table tennis, the ball speed will be higher than expected, which is interesting enough for sports competitions, but I want to enjoy the rally Amateur players, especially the elderly and disabled, can't keep up with the speed, and rather than enjoy, it can cause table tennis and even sports.
