Γ 3 1 7642333 ffe patent supplement, revised ageless manual replacement page • revised period: March 1998 • The racket 1 can be used to make the surface of the central portion of the main ball c The tension and the elastic force are large, and the force is greater at the moment of swinging the badminton. Therefore, the sweet spot of the hitting ball of the racket is mainly in the central area of the main hitting portion C. When the hitter grasps the center of the ball on the main hitting portion c at the moment of hitting the ball, a good swinging force is generated to achieve a strong hitting effect. In addition, under the same force, the larger the force arm is, the greater the torque is generated. When the badminton ball is hit by the upper portion of the main ball striking portion c, the force arm of the swipe is larger than the central region. The resulting batting force will be larger and the badminton flying faster. On the contrary, when the badminton ball is hit by the lower portion of the main ball striking portion C, the swiping force arm is shorter than the central region, resulting in The impact of the ball is smaller. The badminton is also slower. In the design of the racket 1, the racket made of the rod 32 which is less elastic and less elastic can provide a relatively easy and comfortable swing feeling, but if the stick is not grasped, When placed in the central area of the main ball striking portion c, it is not possible to achieve a good hitting effect; further, for a person with good strength, such as a racket made of a rod 32 having a higher hardness and a lower elasticity, Although the speed of the volleyball racquet can be increased, the speed and explosiveness of the badminton flight will also be limited. Therefore, in general, the racket 1 is designed to be made of a rod 32 having a lower hardness or a lower hardness, and it is difficult to meet the needs of different strengths. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a replacement page for a description of a patent application that can be used to enhance the addition and correction of the main hitting D 1 patent application. • Revision date: Upper section of the March 1998 section The surface tension and elasticity produce a large hitting force on the sphere. Therefore, the racket of the present invention comprises: a ring frame, a grip bar connected to the ring frame, and a net set on the ring frame. Each of the latitude and longitude lines of the racquet jointly defines a main ball striking portion, and a sub-ball striking portion located at a periphery of the main ball striking portion and connected to the ring frame, and located at the main ball striking portion and by two adjacent Each mesh surrounded by the warp and weft is gradually reduced from the bottom of the ring frame toward the top. According to the invention, the surface tension and elasticity of the upper portion of the main ball striking portion can be improved, and a large striking force is generated on the spherical body. Therefore, when the player with better strength is attacking violently, he can choose to swing the ball in the upper part of the main hitting ball to extend the arm, and can generate a strong hitting force; The racquet made by the hard, less flexible body can increase the impact of the ball on the ball to greatly increase the speed of the racquet and the ball. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 2 and FIG. 3, the racket 5 of the present invention comprises: a ring frame 6, a grip 7 connected to the ring frame 6, and a net 8 disposed on the ring frame 6. In the present embodiment, a badminton racket is taken as an example for illustration. Of course, the present invention can also be made into a tennis racket or a racquet, which is not limited to the badminton racket of the embodiment. No. D specializes in the age of view, repairs the book replacement page correction period: in March 1998, the ring frame 6 is provided with a plurality of radially extending through holes 63, and the ring frame 6 also has an arc A bottom portion 61, and a top portion 62 that is curved relative to the bottom portion 61. The grip 7 is provided at the bottom 61 of the ring frame 6. The grip 7 has a grip 71, and a rod 72 provided at one end of the grip 71 and coupled to the bottom 61. The web 8 includes a plurality of warp threads 81 extending from the bottom 61 of the ring frame 6 toward the top 62, and a plurality of wefts 82 interlaced with each warp 81, and most of which are surrounded by two adjacent warp and weft lines 81, 82. In the mesh 80, the aforementioned warp and weft lines 81, 82 jointly define a main ball striking portion A (the range surrounded by the imaginary line of FIG. 3), and a ring is located at the periphery of the main ball striking portion A and the ring frame Each of the meshes B connected to the second ball striking portion B and located at the main ball striking portion a and surrounded by two adjacent warp and weft threads 81, 82 is from the bottom 61 of the ring frame 6 toward the top 62 The direction is gradually narrowing. Specifically, the warp threads 81 and the weft threads 82 are respectively passed through the set holes 63, and the warp and weft are interleaved. The start end and the end end of the warp threads 81 and the weft threads 82 are usually fixed to the ring frame 6 by knotting. However, it is not limited to this, so as to constitute these nets. In order to match the mesh 80, which is gradually reduced by the bottom 61 of the ring frame 6 toward the top 62, the closer the two sides of the ring frame 6 are to the curved top portion 6 2, the smaller the spacing is, and the top is located at the top. The closer the spacing holes 63 of 62 are to the center of the top 62, the smaller the spacing. In addition, in order to avoid wear of the warp threads 81 and the weft threads 82, a line eye pad 9 is embedded in the set holes 63 for the warp threads 81 and the weft threads 82 to pass through, since the eye pad 9 is a conventional member, not The subject matter of the invention is therefore not described herein. No. 1 patent application is added, and there is no secant instruction replacement page after correction. • 丄 丄 l , , 丄 曰 · · _ _ _ _ _ _ _ _ _ _ The spacing between the two adjacent wefts 82 is gradually reduced from the bottom 61 of the ring frame 6 toward the top ^, and further, the spacing of the net 8 at the adjacent warp 81 of the main ball striking portion A is also It is gradually reduced by the bottom 62 of the frame 6 toward the top 61. The racquet 5 of the present embodiment is designed such that the surface tension, the elastic force and the maximum torque generated are concentrated in the upper region of the main ball striking portion A. The reason is that each mesh 80 is gradually reduced from the bottom 61 of the ring frame 6 toward the top two directions, and its surface tension and elastic force are gradually increased relatively; and under the force of the same waving racket 5, the arm is more The greater the torque generated by the big one, the torque generated by the hitting will gradually increase from the bottom Μ of the ring frame 6 toward the top 62; thus, in the case where the surface tension, the elastic force and the torque are increased, The upper portion of the main ball striking portion A can exert a great force on the badminton ball. When the player with better strength hits the ball in an instant, if you want to carry out a powerful smash attack, you can choose to use the upper ball area of the main hitting ball A to swipe the badminton ball to extend the arm to generate a larger hitting force. . In addition, the racquet 5 made of the harder and less elastic rod 72 can increase the hitting force of the badminton ball to greatly increase the speed of the swinging ball #5 and the badminton flight. And achieve a strong attack effect. In summary, the present invention is designed to increase the surface tension and elasticity of the upper portion of the main ball striking portion, and to generate a larger hitting force on the ball to greatly increase the speed of the swinging of the racket and the ball. The object of the invention can be achieved. • Supplement to the patent application No. 131^642333, the revised uncorrected specification, the replacement page, the revision period: March, 1998', but the above is only the preferred embodiment of the present invention, and cannot be limited thereto.
