Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a racket, and more particularly to a racket having a good vibration absorption effect.

[0002]

[Prior art]

 A current racket structure is generally composed of a head portion 1, a neck portion 2 and a grip portion 3, as shown in FIG. In recent years, racket manufacturers have often designed shock-absorbing and anti-vibration structures in the grips and used special materials to reduce the injuries to the human body caused by the vibration force generated when hitting a ball. doing. This type of structure can reduce the vibration force felt by the user's hand, but in reality, the vibration source of the racquet is the vibration wave generated when the gutter of the hitting surface hits the ball. As shown in Fig. 1, one manufacturer designs the seismic agglomerate 4 on the ball striking surface, so that the vibration wave formed on the ball striking surface is absorbed and reduced by the seismic mass 4, and transmitted to the grip from the ball striking surface. Vibration is reduced.

[0003]

[Problems to be solved by the invention]

 However, the above-mentioned structure has little effect on absorbing and removing the vibration wave of the racket, for the following reason. A typical racket striking surface has as many as 70 or so vertical gut lines that are perpendicular to each other, and one seismic agglomerate has only two seismic gut lines that directly reduce vibration. The effect on the gut line is a very small indirect seismic reduction, and the effect of removing the vibration wave is limited. Therefore, a large number of seismic masses must be mounted on the racket. However, attaching a seismic agglomerate to a large area of the ball striking surface will affect the line of sight of the ball striking surface and increase the wind resistance when striking the ball, making it extremely inconvenient. At the same time, these seismic agglomerates are used sandwiched between gut lines, and may fall off the gut when used for a long period of time.

[0004] Accordingly, an object of the present invention is to provide a racket which has a seismic reduction effect directly on each longitudinal gut line of the striking surface and effectively removes vibration waves. Another object of the present invention is to provide a racket that does not obstruct the line of sight when hitting a ball and does not form a large wind resistance. Yet another object of the present invention is to provide a racket suitable for long-term use and without the risk of falling off of the seismic agglomerates.

[0005]

[Means for Solving the Problems]

 According to the means of the present invention for solving the above-mentioned problem, a plurality of gut holes are provided at intervals around the periphery of the head portion. The nail has a strip with a fixed length and a plurality of sleeves of a predetermined height projecting from the strip at an interval, and each sleeve shaft has a predetermined height. A plurality of coverings projecting upwards, each covering is provided with a mounting part and a vibration absorbing part in turn, and each covering is provided with a hole in the axial direction. For this purpose, the isolator of the seismic mass is affixed to the outside of the strip, and the mounting part of the covering is mounted in the cap of the claw cap, and the vibration absorbing part of the covering is the top end of the cap. When the gut is passed through the hole in one covering of the seismic mass, it is passed along the isolator into the hole in the next covering.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. (First Embodiment) First, FIGS. 2 to 4 show a first embodiment of the present invention. In the first embodiment, a concave groove 12 is formed in the outer peripheral edge of the head portion 11 of the racket 10, and a plurality of gut holes 13 having a predetermined diameter are provided in the concave groove 12 at intervals. ing.

The nail 20 has a strip 21 having a predetermined length, a cross-section of the strip 21 having a generally U shape, and a groove chamber 22. The other end of the groove chamber 22 has a predetermined height. A plurality of bushings 23 projecting outward at intervals are provided, and each bushing 23 axis is provided with a bushing 231 in an upward direction. It is bent so that the strip 21 of the nail 20 comes into contact with the groove 12 in the periphery of the head 11 of the racket 10 in an annular direction, and each sleeve 23 is embedded in each gut hole 13 of the racket 10. . The pegs 20 are made of a hard plastic so that each sleeve 23 can be smoothly fitted into the gut hole 13.

[0008] The vibration-absorbing mass 30 is made of a plastic material having a good vibration-absorbing effect, and has a strip-shaped separator 31 having a predetermined length, and a plurality of predetermined heights spaced from the separator 31. Each of the coverings 32 is provided with a mounting portion 321 and a vibration absorbing portion 322 in order from bottom to top, and the covering 32 has a hole 323 in the axial direction. Penetrates. The isolator 31 of the vibration-absorbing mass 30 is attached to the groove chamber 22 of the nail 20. The isolator 31 separates the gut from the hard nail 20 so that they do not come into contact with each other. The mounting portion 321 is mounted in the cannula 231 of the cannula 23 of the claw 20, and the vibration absorbing portion 322 of the covering 32 protrudes outward from the top end of the cannula 23 of the claw 20.

As shown in FIG. 4, due to the combination of the above-mentioned members, the racket gut 40 is passed through the hole 323 of one of the coverings 32 in the vibration-absorbing mass 30 and then along the outside of the isolator 31. Further, it passes through the hole 323 of the next covering body 32. In view of the covered path of the racket gut 40, the design of the isolator 31 and the cover 32 of the vibration-absorbing mass 30 allows the gut to have a rigid structure-like nail 20 and a head 11 of the racket 10 in the path through which the gut 40 passes. And is isolated without contact. At the same time, the design in which the vibration absorbing part 322 of the vibration absorbing mass 30 protrudes has an independent vibration frequency, so that the vibration absorbing effect is good. Further, since the gut is covered and in contact with the mounting portion 321 of the vibration absorbing mass 30 and the isolator 31, the gut has an effect of absorbing vibration energy due to the material characteristics of the vibration absorbing mass 30 itself, and has a vibration absorbing effect. The mounting portion 321 and the isolator 31 of the vibration absorbing mass 30 are in close contact with the nail 20 and the head portion 11 of the racket 10 having a similar rigid structure, and have a frequency of vibration similar to that. Although it does not have the same effect as the vibration absorbing effect of the vibration absorbing part 322, it has a considerable vibration absorbing effect due to the effect of absorbing the vibration energy of the vibration absorbing mass 30 itself. A conventional racket-like gut can directly contact the nail 20 to avoid the resonance effect formed on the head portion 11 of the racket 10.

Second Embodiment FIG. 5 shows a second embodiment of the present invention, which is different from the first embodiment in that an isolator 31 between two covering members 32 of a vibration absorbing mass 30 is provided. At least one vibration absorbing mass 50 made of rubber is further provided at the outer end, which serves to provide the gut 40 with a better vibration absorbing effect.

(Third Embodiment) FIG. 6 shows a third embodiment of the present invention, which differs from the first embodiment in that a vibration absorbing part 322 of a cover 32 of a vibration absorber 30 is attached to a mounting part 321. It has a relatively large cross-sectional configuration, and can provide a better vibration absorption effect. (Fourth Embodiment) FIG. 7 shows a fourth embodiment of the present invention, which differs from the first embodiment in that the outside of the vibration absorbing mass 30 is further covered with a protective sheet 60 made of a hard material. It provides better gut holes to protect the mass 30 and avoids the mass 30 being inconsistent or worn in use.

Here, the advantages of the above embodiment are summarized as follows. (1) The vibration absorption effect is good. Insulated design: The insulated design of the seismic mass 30 prevents the gut from coming into contact with nails and racket frames similar to rigid structures. Independently protruding vibration absorbing structure: The vibration absorbing portion 322 of the vibration absorbing mass 30 independently protrudes out of each of the nails, thereby having an extremely good vibration absorbing effect.

[0013] Double-end vibration absorption method: When hitting a ball, the vibration wave of the gut is directly absorbed or reduced by the vibration-absorbing part 322, the mounting part 321 and the isolator 31 of the vibration-absorbing mass 30 at each end of the gut, and the peripheral vibration-absorbing mass 30 The vibration is indirectly reduced by the vibration absorbing part 322, the mounting part 321 and the isolator 31. (2) Convenient and good structure.

The seismic absorption mass is fixed so as to be fixed around the racket, occupies a small area, there is no troublesome work using a seismic mass like a conventional racket, and there is no wind resistance or gaze surface. And there is no risk of falling off.
