The present invention relates to a tennis racket, and more particularly, to distribute some of the impact force generated when impacting the tennis ball during the game before being transmitted to the frame, the impact force transmitted to the user's arm through the frame step by step It relates to a tennis racket that can be absorbed and dispersed.

1 is a perspective view showing a conventional tennis racket.

Referring to this, the tennis racket 10 is a frame 12 made of an approximately elliptical shape, and the frame 12 is inserted into the inner circumferential surface again at a predetermined distance away from the inner circumferential surface of the frame 12 after being inserted into the outer circumferential surface. Installed in the space between the inner circumferential surface of the intersecting at regular intervals horizontally and wires 16 constituting the net portion 14, and is fitted through the mounting groove 12a formed along the outer center line of the frame 12 It consists of the wire guide member 18 which guide | attaches the wire 16 which comprises the net part 14 firmly.

In addition, the general tennis racket 10 is fitted and coupled over a predetermined angle range on the outer surface of the front end portion of the frame 12 to guide the wire 16 and at the same time the front end and court (Court) of the frame 12 during the game A protective member 20 which prevents the frame 12 from being damaged upon contact with the surface, and extends outwardly along the centerline from the long axis edge of the frame 12, and plays tennis on the net 14; It consists of a support portion 22 having a substantially 'Y' shape to disperse the impact force generated when the ball is impacted, and a handle portion 24 extending from the outer end of the support portion 22 to a predetermined length.

On the other hand, in the structure of the conventional tennis racket 10, the wire guide member 18 to be fitted in the mounting groove 12a is made of a band (帶), the protective member 20 of the frame 12 The wire guide member 18 and the protective member 20 are formed in a piece shape having a width almost covering the outer surface of the tip portion and having a concave portion fitted into the mounting groove 12a along a longitudinal center line. Each of the inner surface of the wire 16 is fitted with a plurality of guide bosses 26 are formed in a structure protruding at regular intervals.

In addition, a plurality of through holes 12b into which the guide boss 26 is fitted are formed in the mounting groove 12a formed on the outer surface of the frame 12 at regular intervals.

In the tennis racket 10 having the general structure as described above, the guide is mounted from the inner surface by mounting the wire guide member 18 and the protection member 20 through the mounting groove 12a formed on the outer surface of the frame 12. With the boss 26 projecting into the frame 12 through the through hole 12b, the wire 16 is fitted from the inside of the frame 12 to the outside through any one of the guide bosses.

Is formed.

However, in the conventional tennis racket made as described above 10 because the wire guide member 18 and the protective member 20 is made of a hard PVC material, injection molding is good, but occurs at the moment of impacting the tennis ball during the game. Impact force that is not properly distributed and absorbed there is a problem that is transmitted to the frame side 12 as it is.

In addition, in the case of the conventional tennis racket 10 is transferred to the handle portion 24 between the support portion 22 extending from the frame 12 and the handle portion 24 extending from the support portion 22. Since there is no separate structure for dispersing and absorbing the impact force, most of the impact force generated at every impact of the tennis ball is transmitted directly to the user's arm. As a result, the smashing motion becomes heavy, resulting in weak power and tennis for a certain period of time. In the case of hitting, there is a problem that tennis elbow phenomenon occurs with extreme pain in the elbow of the user.

The present invention is to solve such a conventional problem, the purpose is that the impact force generated at the moment of impact of the tennis ball is distributed and absorbed primarily in the process of transferring to the frame, the remaining impact force is between the support and the handle It is to provide a new type of tennis racket to be dispersed and absorbed in so that the impact force generated every impact of the tennis ball transmitted to the support and the handle portion can be phased out.
