Tackled on ground.
Here, when the game to badminton is further inquired into, in forehand stroke and the comparison of backhand
In, forehand stroke exists makes the speed of shuttlecock become the tendency of high speed to rapidly shoot down shuttlecock on court,
Corresponding to this, then presence brandishes speed rapidly and brandishes the elongated tendency in track.In contrast, backhand, which exists, brandishes track
The tendency to shorten, and it is more to make shuttlecock be bound to situation about hit back on the battle player court that is not easy to get to.
But as existing racket, when surface element and the back part of frame become symmetric shape, even in just
The batting of above-mentioned property different like that is required under forehand hit and backhand, identical performance can only be also played as frame.
That is, exist when pair performance design frame shape corresponding with forehand stroke, the performance of backhand will decline, on the contrary, when pair
During performance design frame shape corresponding with backhand, the problem of performance of forehand stroke will decline.
This point, as the frame 13 of present embodiment, just can realize different ball-handlings in the table back of striking surface 15
Mode, elastic performance, and then can realize property corresponding with the property of forehand stroke and backhand this two side as described above
It can improve.
In addition, surface element 20 and back part 21 are formed asymmetrical shape, so as to change in forehand stroke and anti-
The air drag that frame 13 is subject under forehand hit, thereby, it is possible to expect the property of this two side of realization with forehand stroke and backhand
The corresponding performance of matter improves.
Next, the material of frame 13 is illustrated hereinafter with reference to Fig. 4.Fig. 4 be for the material to frame into
Line B-B sectional view in Fig. 1 of row explanation.Here, as shown in figure 4, the canister portion 18 of frame 13 is by forming the face side of surface element 20
The rear side formation body 36 for forming body 35 and formation back part 21 is formed.Face side forms body 35 and rear side is formed in body 36
