Description

Novel table tennis equipment

Technical Field

The utility model relates to the field of sports equipment, in particular to novel table tennis sports equipment.

Background

As is known, table tennis is the most popular and classic sport in table tennis series, however, the table tennis is developed to the present, and not only a series of problems of small field space, low ball speed turn rate, less exercise amount, insufficient appreciation, great difficulty in starting hands and the like occur, but also the requirements of people on outdoor fitness sports are severely limited in rainy weather, so that the utilization rate of outdoor table tennis is low, and unnecessary waste of social public resources is caused.

Disclosure of Invention

The utility model aims to provide a set of sports equipment based on a large table, a large wireframe racket and a rubber ball, and aims to provide sports which are more ornamental, higher in turn rate, larger in exercise amount, easier to get on hand and can be widely developed indoors and outdoors.

To achieve the above object, the present invention/utility model provides a sport that is realized by:

firstly, 4.75-5.25 cm rubber balls are adopted for movement, the mass is 42.5-47.5 g, the elastic coefficient is 0.61-0.65, the air pressure is 0.0385-0.0415 MPa, the surface smoothness is 3, the color is yellow or white, the light reflection degree is less than or equal to 35% in Munsell, and the specific specification parameters are shown in the attached drawing 1 in detail.

The ball for sports has the main advantages that: (1) the speed is moderate (108 km/h-120 km/h) in the movement process, and the mass is large, so that the device is not easily influenced by windy weather, can be conveniently developed outdoors, and meets the movement requirement of outdoor body building of people. (2) In addition, the ball for sports has stable flight, clear drop points, regular bounce and easy control in the using process, greatly improves the participation of sports, greatly improves the turn times, makes the learning of new people easier and is more convenient for the popularization of the sports. (3) The sports ball is resistant to hitting and wear, the service life of the sports ball is far longer than that of a similar table tennis ball and a similar badminton ball, the sports cost can be greatly reduced, and popularization of the whole people are facilitated.

Secondly, the racket adopted by the sport is a wire racket made of aluminum or carbon, the mass of the wire racket is 140-160 g, the thickness of the racket frame is 1.10-1.30 cm, the height of the racket frame is 2.0-2.4 cm when the racket frame is horizontally placed, the cross section of the racket frame is an ellipse, the handle is a No. 1 handle, the length of the whole racket is 40.5-44.5 cm, the length of a long shaft of a racket surface is 24.35-26.85 cm, the length of a short shaft is 22.0-24.0 cm, the wire arranging mode is 16 multiplied by 16, the diameter of a wire is 0.1-0.15cm, the pound number of the stay wires is 42.5-47.5 pounds, and the specific specification parameters are detailed and shown in figure 2. The racket surface area of the racket is twice as large as that of a table tennis racket, the racket holding mode is a feather net type holding method, the racket more accords with the characteristics of human mechanics, and the main advantages of the racket are as follows: (1) the force is easy to exert, and the force is more sufficient and full due to the holding and the change of the gravity center, and the motion sense is stronger; (2) the racket has better ball contacting effect and higher fault-tolerant rate, is convenient for new people to learn and is beneficial to the wide development of the national fitness; (3) the ball-touching machine has more balls, the number of rounds is increased, the technical and tactical combination of players is richer, and the ornamental value of the match is greatly improved.

Thirdly, the table adopted by the novel table tennis sports equipment is an assembled table top. The table top is mainly composed of six hard composite boards, wherein four hard composite boards with the type A have the size specification of 118.5-121.5 cm in length, 108.5-111.5 cm in width and 2.5-3.5 cm in thickness, the average value Ra of the surface roughness is 0.30-0.50, the elastic kinetic energy loss of the table top is less than or equal to 15%, and the maximum depression of a central stress area is 1.0cm under the pressure of a 75Kg object; the two hard composite boards with the model B have the size specification of 118.5-121.5 cm in length, 218.5-221.5 cm in width and 2.5-3.5 cm in thickness, the average value Ra of the surface roughness is 0.35-0.55, the elastic kinetic energy loss of the table top is less than or equal to 20%, and the maximum depression of the central stress area is 1.0cm under the pressure of a 75Kg object; the six hard composite boards are assembled into the table top of the sports equipment under the support of the base, and the table top has the size specification of 455.0-465.0 cm in length, 217.0-223.0 cm in width, 2.5-3.5 cm in thickness and 67.5-73.5 cm in height from the ground. A2.5 cm wide white line is drawn on the periphery of the table top, a net is pulled in the middle, and a 2.5cm wide rear line of a tee area is drawn at the positions 120.0cm away from the left side and the right side of the net. In addition, the net and the net columns of the table are similar to table tennis net columns, except that the length of the net and the net columns is changed into 225.0-235.0 cm, the height of the net and the net columns is changed into 24.5-25.5 cm, the height of the stand columns on the two sides is 25.0-26.0 cm, the rest of the net and the height of the stand columns on the two sides are the same as those of common table tennis nets on the market at present, and materials can be conveniently selected and assembled. The details of the specification parameters are shown in figure 3. The main advantages of the table are: (1) the desktop is large: 3 times of the common table tennis table, greatly increases the falling point range of the ball, enables the player to receive the ball by continuous movement, and improves the sport participation; (2) the large table top ensures that the preparation time for the athletes to catch the balls is more and the tactical playing method is more abundant; (3) the height of the net is increased, so that the difficulty of the spin-down ball is increased, the bounce of the ball is higher, the opposite attack situation is easier to occur, and the competition is more violent and more wonderful; (4) the large table top enables the ball to have more movement routes and falling points, greatly increases the ornamental value of the match and is convenient for holding and popularizing the match; (5) the large desktop enables the fault tolerance of the falling point of the ball to be larger, attack is more convenient, meanwhile, the large desktop can also be used for more effective defense, people can be helped to release pressure, the amount of exercise is improved, and physical health is promoted.
