Detailed Description

Referring to fig. 1 to 3, a first embodiment of a racket structure for increasing hitting power and shock absorption is disclosed, which comprises:

a racket frame 10 has a recessed portion 13 recessed from an outer circumferential surface thereof at a predetermined position along an axial direction of a frame body, the racket frame 10 has a plurality of through holes 11 formed in the recessed portion 13, and a plurality of protrusions 12 are protruded from the recessed portion 13 at regular intervals so that the through holes 11 are formed between the protrusions 12. In the first embodiment of the present invention, the protruding portions 12 are spaced apart from the through holes 11, and two through holes 11 are spaced apart between adjacent protruding portions 12.

An elastic sheet 20 made of resilient material, disposed in the concave portion 13 and straddling the convex portions 12, wherein a deformation space is formed under the elastic sheet 20 by the support of the convex portions 12. Wherein, the elastic piece 20 can form a limit position through the side wall of the concave part 13. The elastic sheet 20 is provided with a through hole 21 at the position corresponding to the through holes 11. The elastic piece 20 may be provided at all or any predetermined position of the racket, particularly, the string through which the sweet spot of the racket passes, for example, at the upper edge of the frame 10, or at the right and left edges of the frame 10, and in the first embodiment of the present invention, the elastic piece 20 is provided at the upper edge of the frame 10. The elastic sheet 20 may be made of any material having resilience, and in the first embodiment of the present invention, the elastic sheet 20 is made of a high-entropy alloy (high-entropy alloy) which is an alloy obtained by refining a plurality of metals, and has not only excellent flexibility and resilience, but also fracture resistance, tensile strength, oxidation resistance, and the like superior to those of conventional alloys.

The wire protecting nails 30 are disposed in the through holes 21, and the mesh wire 40 can be inserted into the wire protecting nails 30, so as to prevent the edges of the through holes 21 of the elastic sheet 20 from scratching the mesh wire 40, thereby achieving the effect of protecting the mesh wire 40. The wire-protecting nails 30 include a wire inlet pipe 31 and a wire outlet pipe 32, and the wire inlet pipe 31 and the wire outlet pipe 32 are respectively inserted into the corresponding through hole 11 and the through hole 21. In the first embodiment of the present invention, the wire inlet pipe 31 and the wire outlet pipe 32 are respectively disposed in the two through holes 21 between the adjacent convex portions 12, so that none of the wire protection nails 30 crosses the convex portions 12.

One end of each of the net strings 40 penetrates through the through hole 11 of the racket frame 10 and the through hole 21 corresponding to the elastic piece 20, and the other end transversely spans the outer surface of the elastic piece 20 and then penetrates through the through hole 11 adjacent to the racket frame 10 and the through hole 21 corresponding to the elastic piece 20, so that a net-shaped racket face for hitting is formed in the racket frame 10. In the first embodiment of the present invention, the two ends of the net thread 40 penetrate through the thread-protecting nails 30 through the through holes 11 and the through holes 21 between the adjacent convex portions 12 and transversely straddle the outer surface of the elastic sheet 20, and in detail, the net thread 40 penetrates through the thread-protecting nails 30, penetrates through the corresponding through holes 21 from the through holes 11, winds around the outer surface of the elastic sheet 20 along the thread-protecting nails 30, winds around the adjacent through holes 21, and penetrates out of the corresponding through holes 11 to the inner side of the racket frame 10.

Thus, the net thread 40 can make the elastic sheet 20 compressed to be closely attached to the convex portions 12 by its tension.

For a further understanding of the nature of the structures, means of employment and intended efficacy of the invention, reference should now be made in detail to the use of the invention, a more complete and detailed understanding of which is believed to be obtained by the following:

as shown in fig. 4, when the ball is hit with the racket, the string 40 contacting the ball 200 will generate a force for pulling the elastic sheet 20 downwards due to the hitting of the ball 200, and at this time, since the elastic sheet 20 has an excellent resilience and a deformation space is formed between the elastic sheet 20 and the racket frame 10, the elastic sheet 20 will generate a downward bending deformation, so that the string 40 extends downwards, and the depth of the ball 200 pushing into the string 40 is increased, and when the ball 200 is further hit back by the racket, the string 40 contacting the ball 200 can hit the ball 200 with a larger resilience due to the resilience generated by the elastic sheet 20 itself, so as to generate a larger hitting force and exert a better hitting effect.

In addition, because the tight net thread 40 forms an amplitude, the amplitude of the net thread 40 changes the tension thereof and causes vibration, and is transmitted to the elastic sheet 20 along the net thread 40, the change of the tension of the net thread 40 causes the change of the pulling force to the elastic sheet 20, because the elastic sheet 20 has excellent elasticity, the elastic sheet 20 can deform along with the change of the tension, thereby greatly weakening the influence of the change of the tension, and simultaneously absorbing and buffering the vibration of the batting, greatly reducing the vibration transmitted to the racket frame 10 and the racket handle, thereby achieving the effects of shock absorption and buffering, and effectively reducing the discomfort or the injury of the motion to the racket holder.

Please refer to fig. 5, which discloses a second embodiment of the present invention, the difference between the second embodiment of the present invention and the first embodiment of the present invention is that an elastic body 60 is respectively disposed between the elastic sheet 20 and the racket frame 10 at the corresponding position where the net wires 40 transversely span, and the elastic body 60 is made of elastic material, such as PU foam, so that the elastic sheet 20 and the elastic body 60 can generate better elasticity together, and the elastic body 60 can also be used as a cushion for shock absorption to achieve better shock absorption effect.

Referring to fig. 6, a third embodiment of the present invention is disclosed, which is different from the first embodiment of the present invention in that: the mesh wire 40 passes through the through holes 21 at the left and right sides of the convex portions 12, and is spanned on the outer side surface of the elastic sheet 20 at the positions corresponding to the convex portions 12. The remaining structural features and the effects achieved by the third embodiment of the present invention are substantially the same as those of the first embodiment of the present invention, and thus are not described in detail.

Referring to fig. 7 to 9, a fourth embodiment of the present invention is disclosed, which is different from the first embodiment of the present invention in that: the protruding parts 52 are located on the recessed part 51 along the axial direction of the racket frame 50, and are respectively arranged on both sides of the recessed part 51, the elastic piece 20 is also arranged on the protruding parts 52 in a straddling manner, and a space for deformation is still formed below the elastic piece 20 by the support of the protruding parts 52. The remaining structural features and the effects achieved by the fourth embodiment of the present invention are substantially the same as those of the first embodiment of the present invention, and therefore, the description thereof is omitted.

Referring to fig. 10 to 11, which illustrate a fifth embodiment of the present invention, the protruding portions 72 are also located on the recessed portion 71 and are disposed along the axial direction of the racket frame 70, and are respectively disposed on two sides of the recessed portion 71, and the elastic piece 20 is also disposed across the protruding portions 72, which is different from the fourth embodiment of the present invention in that: the racket frame 70 is penetrated through the inner side and the outer side at the position of the recess 71, so that the net strings 40 have a larger swing space and can generate a larger elastic force.

The features of the invention and their expected effects are further set forth below:

1. the elastic piece 20 of the present invention has excellent resilience, and a deformation space is formed below the elastic piece 20, so that the elastic piece 20 can generate a deformation space, and the elastic piece 20 can provide the resilience generated by itself, so that the net wire 40 can drive the ball 200 out with a larger resilience, thereby generating a larger hitting power and exerting a better hitting effect.

2. The invention can utilize the elastic sheet 20 to buffer the vibration of the batting when the batting is performed so as to reduce the vibration transmitted to the racket handle, thereby achieving the effects of shock absorption and buffering, ensuring that a holder of the racket hardly feels the vibration when the batting is performed, and effectively reducing the discomfort of hands or the injury of sports caused to the holder of the racket.
