Description

Floor ping pong, racket and table tennis ball

The invention relates to a new type of competitive ball sports ball and a table tennis ball and a racket and a table tennis ball.

Background technique

Competitive sports are popular among people, such as table tennis and tennis. For ordinary people, table tennis is easy to learn and easy to practice but requires a table. It can't be carried out anytime and anywhere. Tennis is more difficult to learn and runs a larger range. The ball speed is faster, the amount of movement is relatively larger, and the round is less.

The table tennis ball movement is a new type of competitive ball sport. It was founded and named in 1990-2007 by the teacher Liu Tianyang of the Guangzhou Sports Institute in combination with the characteristics and rules of table tennis and tennis. It also has many characteristics of table tennis and tennis. . The table tennis ball game is bigger than table tennis and smaller than tennis. It is a brand new sport that combines the characteristics and advantages of two sports. Compared with table tennis, it has a wide range of activities, easy to learn, easy to practice, more powerful, more rounds, more exercise, less suitable for men and women, less field restrictions, easy to practice anytime, anywhere; For tennis, it has a small range of running, slower ball speed, more change in rotation, more skill, and more rounds.

After many years of continuous summarization and improvement, it has been basically fixed. Because the table tennis ball movement has many characteristics of table tennis and tennis, but it is different, the stadium and equipment used in redesigning the table tennis ball is to promote this. An important topic of the sport.

Summary of the invention

The technical problem to be solved by the present invention is to provide a golf course device suitable for the table tennis ball competition and a ball for the table tennis ball and the ball for the table tennis ball.

The technical solution of the present invention to solve the above problems is:

A new type of competitive ball sports, a table tennis ball game, characterized in that: the course is composed of a net (1) And the grid, the score within the site (2) composition, the length of the inner site is greater than or equal to 6 meters, less than or equal to 12 meters; the width of singles is greater than or equal to 2 meters, less than or equal to 6 meters, doubles when greater than or equal to 3 meters, Less than or equal to 7 meters; the height of the net is greater than or equal to 0.5 m, less than or equal to 0.8 m, spanning the middle of the length of the inner field.

More precisely:

The inner field (2) is equal to 8 meters in length, 3 meters in width singles, 3.4 meters in doubles, and 0.75 meters in height.

The inner field (2) is composed of a whole floor or is composed of at least two pieces of flooring, which are wood, bamboo, plastic, glass, metal, cement, acrylic building composite materials and splints between them 5米以上。 The thickness of at least 0. 02 meters, the hardness is required to be a table tennis ball from a height of 0. 5 meters free fall can bounce more than 0.3 meters.

A racket specially designed for the above-mentioned new type of competitive ball sports, which is characterized in that: the racket (3) consists of a bottom plate (4) and a handle (5), a high-elastic sponge (6) and a rubber skin ( 7) The bottom plate is flat and hard on both sides; the handle is a bottom plate extending along one end of the long axis or fixed by a connecting rod and a bottom plate; the high elastic sponge is a sponge having two sides flat and having certain elasticity; the rubber skin is flat and The other side is evenly distributed with particles; at least one side of the bottom plate is pasted with a high-elastic sponge and rubber.

More precisely:

The front end of the racket handle link is connected to the bottom plate to form a hollow shockproof structure.

The bottom plate is elliptical or rectangular.

The bottom plate is composed of wood or glass, plastic, carbon, titanium metal and its fibers, and nano high elastic composite material. The ping-pong ball, which is specifically designed for use in the above-mentioned new type of athletic ball sports, is characterized in that: the floor ping ball is a sphere, and the outer diameter of the ball is greater than or equal to 0.04 meters, less than or equal to 0. 06米, The ball is greater than or equal to 2. 7 grams, less than or equal to 50 grams.

More precisely: The outer diameter of the table tennis ball is greater than or equal to 0. 042 meters, less than or equal to 0. 043 meters, the ball is greater than or equal to 3 grams, less than or equal to 4 grams.

The floor ping ball is a circular hollow sphere.

The above-mentioned course and racket and table tennis ball belong to the same general inventive concept. A new type of competitive ball sports and a table tennis game are invented. The three are related to each other. The specific technical feature between them is the table tennis ball movement. As mentioned above, the table tennis ball has many characteristics of table tennis and tennis. Specifically, the venue is larger than the table tennis table. It is smaller than the tennis court. It also requires the racket to be larger than the table tennis racket. It is smaller than the tennis racket and the table tennis ball. Table tennis is big, smaller than tennis.

The stadium and the racket and the table tennis ball Trinity can reflect the contribution of the table tennis ball to the existing sports, and the ball and the table tennis ball will not be allowed to be used for other things such as table tennis. Tennis match.

Advantageous Effects: The table tennis ball court, the racket and the ball of the present invention are most suitable for the competition of the new type of competitive ball sports and the table tennis ball. The venue is larger than the table tennis sport but slightly smaller than the tennis court, and the amount of exercise can be large. Can be small, more suitable for men and women, younger and younger practice, more rounds, fewer venue restrictions, easy to practice anytime and anywhere; in order to adapt to the above venue, the table tennis ball racquet is larger than the table tennis bat but slightly smaller than the tennis racquet, easy to learn, easy to practice The force is smoother; the ball for the table tennis ball is slower than the tennis ball, the rotation is more varied, the skill is stronger, and the turn can be more.
