The racquet body comprises a frame section and a handle section that is arranged at the lower side center of the frame section. The racquet net comprises a plurality of first cords and a plurality of second cords. The first cords have elasticity that is greater than that of the second cords and the second cords have stiffness that is greater than that of the first cords. The plurality of first cords and the plurality of second cords are respectively longitudinally and laterally staggered in the interior of the frame section so as to form a net body having a predetermined tension.

Description

racket

The invention mainly discloses a racket, in particular a racket comprising two different elastic and rigid beat lines.

The racquet used in general racquet sports has a racquet face, which is the part that the batsman uses to hit the ball, and the chord face is woven by using a string of strings to cross the racquet frame or other forms.

Please refer to FIG. 6 , which is a schematic diagram of the force deformation of the chord surface of the racquet with a high-rigidity racquet. The chord face of Fig. 6 is woven by a longitudinally extending high-rigidity chord 80 and a horizontally extending high-rigidity chord 80, so that the deformation of the high-rigidity chord 80 is quite small when the ball S is swiped, and the racquet is shocked. High, the burden on the player's hand is great, and the requirement for strength is also high, because the racquet's chord is very hard at this time, and there is not much buffer space. The use of the racket with high rigidity and string 80 is used. They usually have to be formally trained to understand the skills and ways to protect themselves. If a general user uses a high-rigidity racquet with a high-strength string 80, it usually has a hand pain or injury and shortens its exercise life. On the other hand, the racket life of the racket of the high-rigidity string 80 is very short, especially the longitudinally extending high-rigidity string 80 because of the long extension distance, in extreme cases, it may be broken from several days to several hours.

Please refer to FIG. 7 , which is a schematic diagram of the force deformation of the chord surface for the racquet with a high elastic racquet. Figure 7 is a high-elasticity The tempo string 90 is woven with a horizontally extending high elastic chord 90. When the ball S is swiped, the high elastic chord 90 produces a shape variable D, so that the ball S has a stagnant time on the chord surface when hitting the ball. Moreover, the direction of the sphere S is not well controlled. As long as the sphere S is not in the sweet spot of the string surface, the flight direction of the sphere S may be offset from the swing direction by a certain angle, but relatively, a high elastic string is used. The user of the racket pulls the ball and the sling ball because the elasticity is less laborious, but the falling point of the sphere S cannot be accurately controlled.

In view of the above problems of the prior art, which cannot be effectively solved and overcome, the present applicant has filed this patent application to solve the aforementioned problems.

It is an object of the invention to provide a racket.

To this end, the present invention provides a racket comprising: a photograph body and a beat net, the photograph body having a frame portion and a rack portion disposed at the center of the lower end of the frame portion, the net The first beat line and the plurality of second beat lines are included, and the elasticity of the first line is greater than the second line, and the rigidity of the second line is greater than the first line, and the first line is The plurality of second beat lines are interlaced with the warp and weft in the frame portion to form a net body having a predetermined tension.
