[Prior art]

  Modern people are increasingly paying attention to exercise to maintain their health. Therefore, when designing and improving various exercise equipment, it is used to motivate users to purchase. The main appeal of the design is the comfort level of the user's use and the property of reducing the movement injury. ball For the technical racket, in addition to the grip comfort of the grip part, another important point is And how to reduce the vibration force generated at the time of impact to the minimum Transmission to the user's hand through Rasuka can be mentioned. This will allow the vendor to add elasticity to this point. We have researched and developed a shock absorber that can be fixed to the racket striking surface according to actual needs. This The shock absorber is usually made of a soft elastic body, and depending on its shape design, the side or bottom The holding groove is opened in the surface, the shock absorber is placed on the inner edge of the racket striking surface, and The shock absorber is fixed to the striking surface by sandwiching the stopper. When the user hits on the striking surface, The vibration force and noise generated by the impact of the striking surface and the ball are due to the soft elastic characteristics of the shock absorber. It is more absorbed, but it is unavoidable that the shock absorber will affect the area of the ball on the striking surface. Yes. As a result, this shock absorber can be fixed only to the inner edge of the striking surface, The absorption effect of vibration force and noise is finite, and the surplus vibration force is applied to the user through the grip. Is transmitted to the hands of the user, and the user's hands feel unsuitable for vibration. Such a design is ideal for use. I can't say that.

[0003]

[Problems to be solved by the device]   The main purpose of the present invention is to provide a kind of racket gut sound absorber Yes, it utilizes a metal ball placed in a shock absorber to effectively racket strike. Absorbs sound and vibration generated when striking the striking surface, reduces noise and uses vibration The transmission to the hand of the person shall be reduced.

[0004]

[Means for Solving the Problems]

  According to the invention of claim 1, the racket gut is provided on the surface of the shock absorber formed of a soft elastic body. A holding groove for holding the shock absorber is opened so that the shock absorber can be fixed between the racket gut. Then, a housing hole is provided in a predetermined portion inside the shock absorber, and one metal button is inserted in the housing hole. When the racket is placed and hit with a racket, the metal balls will Characterized by being configured to achieve sound absorption and vibration absorption by generating vibration It is used as a sound absorbing shock absorber for the racket gut.   The invention of claim 2 is the sound absorbing shock absorber for a racket gut according to claim 1, One hole is provided on the vertical surface of the shock absorber, and the hole is extended inward to accommodate the shock absorber in the shock absorber. It is a sound absorbing shock absorber for a racket gut, which is characterized by communicating with the hole.   The invention of claim 3 is the sound absorbing shock absorber for the racket gut according to claim 1, The shock absorber has an arbitrary shape that can be fixed between the racket gut, It is used as a sound absorbing shock absorber for the racket gut.

[0005]

[Embodiment of device]

  See FIG. The sound absorbing shock absorber 1 of the racket gut of the present invention has soft elasticity. And a holding groove 11 having a predetermined length is formed on the surface of the shock absorber 1, One hole 12 is provided on the vertical surface, and the hole 12 is extended inward so that the inside of the shock absorber 1 It communicates with the accommodation hole 13 opened in a predetermined portion between them, and one metal button is inserted in the accommodation hole 13. Rule 2 is put in.

[0006]   At the time of manufacturing, the inner surfaces of the upper mold and the lower mold are formed into a predetermined shape, and the predetermined holes of the lower mold are formed. Place the pin in the opened cavity and make the front end of the pin relatively long in diameter. After making a large circle, after that, the upper mold and the lower mold are combined, and the molten resin is poured into the mold. When the mold is opened after curing, it has the same internal shape as the upper and lower molds and is a soft elastic body. A vessel was formed, which is as shown in Figure 2, where the pins were placed in this mold. Since the inside of the shock absorber 1 is formed with an inwardly extending hole 12, The front end of the pin is formed into a circular body having a relatively large diameter, so that the inside of the shock absorber 1 is An accommodation hole 13 having a relatively large hole diameter is formed in a predetermined portion between the holes. The shock absorber 1 is soft Since it is made of elastic material, the elasticity of the hole 12 is utilized, and the diameter of the metal is larger than that of the hole 12. The ball 2 is inserted in the hole 12 as well as in the accommodation hole 13 to provide a cushion A metal ball 2 is provided at a predetermined portion in the middle of the container 1.

[0007]   See FIG. When in use, the shock absorber 1 is attached to the two inner edges of the racket 3 It is placed between the guts 31 separated from each other, and the racket 3 is held in the holding groove 11 on the surface of the shock absorber 1. The gut 31 is sandwiched and the shock absorber 1 is fixed between the guts 31 of the racket 3. use When a person hits the ball with the impact surface, the impact vibration force generated by the impact surface and the sphere impacts the metal ball 2. The soft elastic shock absorber causes the impact force and noise generated by the impact surface and the ball to be vibrated at a high frequency. 1 and the metal balls in the shock absorber 1 are absorbed by high frequency vibrations, which The generation is reduced, and the impact vibration force is not transmitted to the user's hand through the grip, As a result, the vibration force felt by the user at the time of impact can be reduced.

[0008]   FIG. 4 shows another embodiment of the present invention. In this embodiment, the bottom surface of the shock absorber 4 and the And a holding groove 41 is formed on the side surface and one hole 42 is formed on the vertical surface of the shock absorber 4. , The hole 42 is extended inward, and the hole formed at a predetermined portion in the middle of the shock absorber 4 is The metal ball 5 is placed in the accommodation hole 43 so as to communicate with the accommodation hole 43.

[0009]   In use, the shock absorber 4 is placed on the inner edge of the racket 6 as shown in FIG. , Using the holding groove 41 provided on the bottom surface and the side surface of the shock absorber 4, The shock absorber 4 is clamped and the shock absorber 4 is fixed to the striking surface. When the user hits on the striking surface The vibrating force generated by the collision of the striking surface with the ball is high in the metal ball 5 in the accommodation hole 43. Frequency vibration is generated, whereby the noise and vibration force of the shock are generated by the soft elastic characteristics of the shock absorber 4. And the high frequency vibration of the metal ball 5 absorbs the noise and reduces the noise. The vibration force transmitted to the user's hand is reduced.

[0010]

[Effect of device]

  With the above structure, the metal ball is installed at a predetermined position in the middle of the shock absorber. When the impact force is received, the vibration force generated by the impact force is When a vertical vibration is generated rapidly in the housing hole and a high frequency vibration is generated, and the object is hit with a hitting surface. Absorbs the noise and impact force of. This shock absorber has the soft elasticity characteristic of the shock absorber itself. Not only does it absorb more noise and vibration, but it also causes noise due to the high-frequency vibration of the metal balls. Since it absorbs the vibration force, it can reduce the generation of noise and it can be put on the user's hand. The surplus vibration force transmitted can be reduced, and the vibration generated in the user's hand To reduce noise and vibration force effectively. Therefore, the conventional racket Shock absorber has only sound absorbing and absorbing functions due to its own soft elastic properties Compared with the other, the sound absorption and vibration absorption are more excellent and the functional effect is enhanced. It
