===about racket 1===

To using the example of badminton racquet as racket of the present invention, illustrated embodiments below.Fig. 1 is front view and the perspective view of badminton racquet (being below racket 1).Note, the figure on the left side is front view and the figure on the right is perspective view.Fig. 2 is the front view of the first half of the frame 10 of racket 1.This racket 1 has dabber 20, frame 10, handle 30, claps line 40 and thread-protected tube 50, and frame 10 engages longitudinal tip side of dabber 20, and handle 30 engages longitudinal rear end side of dabber 20, claps line 40 in the tension of the inner side of frame 10, and claps line 40 through thread-protected tube 50.In elaboration, perpendicular to the direction longitudinally of the face that impacts of racket 1 (taking taxi in plane along hitting), be called width, and be called thickness direction perpendicular to hitting of racket 1 direction of taking taxi.

Being shaped as at substantially elliptical extending longitudinally of frame 10.In addition, frame 10 is provided with a plurality of bat line hole 11(corresponding to through hole), clap between line hole 11 circumferencial direction along frame 10, spaced from each other in the almost whole girth of frame 10, clap line hole 11 and pass for clapping line 40, and this bat line hole 11 penetrates into the outer peripheral face 10b of frame from the inner peripheral surface 10a of frame.As shown in Figure 2, thread-protected tube 50 has cylindrical portion 51 and head 52, and described cylindrical portion 51 and described head 52 are provided with the hole of passing for clapping line 40.The cylindrical portion 51 of thread-protected tube 50 is through clapping line hole 11, and stretch out from the inner peripheral surface 10a of frame 10 on the top of this cylindrical portion 51, and the outer peripheral face 10b of head 52 interlock frames 10.

In addition, when bat line 40 is strained in frame 10, for example, from the inner side of frame 10 through described bat line hole 11(thread-protected tube 50) outer peripheral face 10b to the bat line 41 in the outside of frame 10 along frame 10 turns back, and repeats to clap line through the next line hole 11(thread-protected tube 50 of clapping) and action.Result, inner side at described frame 10, many of the region of the bat line 40 of broad ways " level is clapped lines 41 " at the threading of longitudinally turning up the soil to each other, and many " vertically the clapping line 42 " in region of longitudinally clapping the crossing bat line 40 of line 41 with level are at the width threading of turning up the soil to each other.Thereby form the netted face that impacts.Note, in frame 10 longitudinal tip side regions, at outer peripheral face 10b, be provided with recess 12, at described recess 12, be provided with the opening of clapping line hole 11, thereby described bat line 40 is turned back at described recess 12.

===about clap line hole 11===

Fig. 3 A and Fig. 3 B are the figure having shown owing to clapping the difference of the mobile range that level that the difference of the penetration direction in line hole 11 produces claps line 41.Adopt racket 1, by making the frame 10(frame 10 of area and hitting the area of taking taxi) diminish, during rotation, air drag declines, and High Rotation Speed becomes possibility, thus the shuttlecock speed in the time of can improving slam-shot.But in the situation that the area of frame 10 diminishes, optimum batting point also diminishes, and controllability declines.Optimum batting point is that repulsive force is high and vibrate little region while impacting.Adopt the frame 10 of substantially elliptical, through the level of side (two end portions of width and longitudinally core), clap line 41 longer than the level bat line 41 through two end portions longitudinally, and the vertical bat line 42 through top (the longitudinally core of tip side and width) is longer than the vertical bat line 42 of the two end portions through width, and while impacting the core in frame 10, the deflection of described bat line 40 is large, thereby makes the core in described frame 10 become optimum batting point.On the other hand, known to spike to improve the speed of shuttlecock with described frame 10 longitudinal tip side regions, and especially, when impacting, experienced player tends to use the interior longitudinal tip side of described frame 10 region.Therefore, racket 1 object is that optimum batting point is extended to the longitudinal tip side in described frame 10 in this embodiment.

Therefore, in this embodiment, as shown in Figure 2, by width and be positioned at respect to shown in the angle θ 1 that forms through direction, that level is clapped many bat line holes 11 that line 41 passes in bat line hole 11 of longitudinal tip side of center O of frame 10 (below also referred to as " angle of penetration ", and corresponding to the first angle) the angle θ 2(that forms than the normal direction (vertical direction of the tangent line of inner peripheral surface 10a) that the position of clapping line hole 11 is set by the inner surface 10a of width and frame 10 below also referred to as " normal angled ", corresponding to the second angle) less.

Particularly, 8 angle of penetration θ 1 that clap line hole 11 (below also referred to as " level is clapped line hole ") are less than normal angled θ 2 altogether, described 8 bat line holes 11 are to clap line 41 in the level of longitudinally alignment, for the 3rd level, clap 2 bat line hole 11a (3) that line 41 (3) passes from longitudinal tip side, 11b (3), for the 4th level, clap 2 bat line hole 11a (4) that line 41 (4) passes, 11b (4), for the 6th level, clap 2 bat line hole 11a (6) that line 41 (6) passes, 11b (6), with 2 bat line hole 11a (8) that pass for the 8th level bat line, 11b (8).Note, the cylindrical portion 51 of thread-protected tube 50 is passed along described bat line hole 11, make through described 8 levels clap line hole 11 thread-protected tube 50 axially and the angle θ 1 of width formation also less than normal angled θ 2.

In addition, adopt the racket 1 of this embodiment, broad ways (described level is clapped line 41 in the direction of the described frame 10 interior extensions) level that penetrates is clapped line hole 11 as much as possible, forms the penetration direction that described level is clapped line hole 11.In other words, to approach as far as possible the penetration direction in the level bat line hole 11 of zero degree, penetrate level bat line hole 11.In Fig. 2, the described the 6th and the 8th level is clapped the level bat line hole 11a (6) that line 41 (6), 41 (8) passes, 11b (6), and 11a (8), the angle of penetration θ 1 of 11b (8) is zero degree.But, be not limited to this, for example, described the third and fourth level is clapped line 41 (3), the angle of penetration θ 1 that 41 (4) levels of passing are clapped line hole 11 can be zero degree, or on the other hand, the described the 6th and the 8th level is clapped line 41 (6), the angle of penetration θ 1 that 41 (8) levels of passing are clapped line hole 11 can be greater than zero degree, maybe can change 2 levels of passing for the level bat line with duplicate numbers and clap the angle of penetration θ 1 in line holes 11.The angle of penetration in the bat line hole 11 of passing for described the first and second levels bat lines 41 (1), 41 (2) in addition, can be less than normal angled.

In this hypothesis, as shown in Figure 3 B, level is clapped the penetration direction (clapping the level bat line hole 11a (4) that line 41 (4) passes, 11b (4) for the 4th level in the accompanying drawings) in line hole 11 along normal direction.In this case, described level is clapped line 41 (4) and is clapped line 41 (4) through the position p3 of the inner peripheral surface 10a of described frame 10 in described level, the degree of crook of p4 is relatively large, and the movement that makes described level clap line 41 (4) is fixed on position p3, p4.Therefore, described level bat line 41 (4) mobile ranges at width become the long Lb between the inner surface 10a of described frame 10.

On the contrary, adopt the racket 1 of this embodiment, the angle of penetration θ 1 that described level is clapped line hole 11 is less than described normal angled θ 2.Therefore, as shown in Figure 3A, compare the situation of Fig. 3 B, described level is clapped line 41 (4), and at it, the angle through the location bending of the inner peripheral surface 10a of described frame 10 can be less, and described level is clapped line 41 (4) can pass the position p1 of the outer peripheral face 10b of described frame 10 at it, p2 is crooked.Therefore, described level is clapped line 41 (4) mobile ranges at width can become the length L a between the outer peripheral face 10b of described frame 10, and compares the situation of Fig. 3 B, and the mobile range of described level bat line 41 (4) is longer.Especially, by the angle of penetration θ 1 that makes described level clap line hole 11, be zero degree, can make more for certain the mobile range of described level bat line 41 (4) longer.As a result, when impacting the region exceeding with respect to longitudinal tip side of the core in described frame 10, the deflection of described bat line 40 can become greatly, and repulsive force can improve.

In other words, adopt the racket 1 of this embodiment, through described 8 levels between the top at described frame 10 and both sides, clap the mobile range of the level bat line 41 in line hole 11 and can clap closer to the described level of the core through described frame 10 mobile range of line 41, therefore, the optimum batting point of described frame 10 interior longitudinal tip side can be expanded, and controllability can be improved.Therefore, though when the area of frame 10 diminish so that High Rotation Speed become may time, also can prevent that optimum batting point from diminishing.In addition, with 10 longitudinal tip side regions whens slam-shot of frame, can improve impacting sensation and flying of shuttlecock, and the racket 1 of this embodiment can be used as the player's who is suitable for using the interior longitudinal tip side of described frame 10 region racket 1.

In addition, adopt the racket 1 of this embodiment, except 8 levels between the top at described frame 10 and both sides, clap line hole 11, clap the penetration direction in line hole 11 along the normal direction that the position in each bat line hole 11 is set on the inner peripheral surface 10a of frame 10.Suppose, the penetration direction of clapping all bat line holes 11 that line 41 passes for level is along width and for the penetration direction of vertically clapping all bat line holes 11 that line 42 passes along the longitudinal, optimum batting point expansion is too many so.In that case, be difficult to determine in described frame 10, which region is suitable for impacting, and on the contrary, controllability declines.And the speed of shuttlecock declines.

Especially, while impacting, experienced player tends to use longitudinal tip side of described frame 10, thereby without the optimum batting point in the position of the longitudinal rear end side with respect to described frame 10 center is broadened.Therefore, adopt the racket 1 of this embodiment, the penetration direction in bat line hole 11 by making to be arranged on described frame 10 longitudinal rear end side is along normal direction, can only expand the optimum batting point of the longitudinal tip side in described frame 10, and may stop the optimum batting point expansion of longitudinal rear end side to exceed required.

In addition, described racket 1 longitudinally longer than width, and the mobile range that the mobile range of described vertical bat line 42 is clapped line 41 than level is wider, therefore, without the mobile range of described vertical bat line 42 is broadened.Therefore, adopt the racket 1 of this embodiment, the penetration direction by being used in the described bat line hole 11 that described vertical bat line 42 passes, along normal direction, may stop optimum batting point to exceed at Longitudinal Extension required.

In addition,, by making the penetration direction in described bat line hole 11 along normal direction rather than broad ways or longitudinal, for example, the drilling operating of doing accordingly hole becomes easy.Therefore, adopt the racket 1 of this embodiment, by making the penetration direction of clapping the bat line hole 11 line hole 11 except described 8 levels along normal direction, can make the drilling operating of described frame 10 easier.

In addition, adopt the racket 1 of this embodiment, be positioned at respect to level described in the described bat line hole 11 of longitudinal tip side of the center O of described frame 10 clap line 41 through and the angle of penetration θ 1 in the bat line hole 11 do not passed of described vertical bat line 42 less than normal angled θ 2.In other words, the penetrating of bat line hole 11 that described level bat line 41 and described vertical bat line 42 pass analyzed along normal direction.For example, in Fig. 2, the 5th and the 7th level is clapped the bat line hole 11a (5) that line 41 (5), 41 (7) passes from longitudinal tip side, 11b (5), and 11a (7), the penetration direction of 11b (7) is along normal direction.

Only compare and clap for one the bat line hole 11 that line 40 passes, the bat line hole 11 of passing for two bat lines 40 has larger bore dia, and in the motion that the level of the inner peripheral surface 10a of described frame 10 is clapped line 41, be more not easy to restrictedly, and the mobile range that described level is clapped line 41 is more not easy to shorten.Therefore, even if in the situation that the penetration direction in the described bat line hole 11 of passing for two bat lines 40, along normal direction, also can prevent that optimum batting point from diminishing.In other words, without making the bore dia change in the bat line hole 11 that only level bat line 41 passes greatly with expansion optimum batting point, thereby can improve the intensity of described frame 10.In addition,, by making two penetration direction of clapping the bat line hole 11 that lines 40 pass along normal direction, can make the drilling operating transfiguration of described frame 10 easy.

In addition, suppose to make two penetration direction of clapping the bat line hole 11 that lines 40 pass along width, so as shown in Figure 3 B, the angle of bend θ 3 of described vertical bat line 42 becomes right angle, or close to the angle at right angle.In that case, while impacting, pressure concentration is in the corner portions located of described vertical bat line 42 bendings.Therefore, by making two penetration direction of clapping the described bat line hole 11 that lines 40 pass along normal direction, can make the angle of bend of described vertical bat line 42 mild, and can stop pressure concentration while impacting, thereby stop the intensity of described vertical bat line 42 and thread-protected tube 50 to decline.Yet, be not limited to this, described level clap line 41 and vertically clap line 42 through and be positioned at can broad ways with respect to the penetration direction in the bat line hole 11 of longitudinal tip side of the center O of described frame 10.

In addition, adopt the racket 1 of this embodiment, for example use than the harder raw material of the raw material of thread-protected tube 50 of clapping line hole 11 through other, as the raw material (, resin) through being positioned at the top of described frame 10 and described 8 levels of both sides and clapping the thread-protected tube 50 in line hole 11.So, the frictional resistance that the described thread-protected tube 50 that the level of passing is clapped line hole 11 and level are clapped between line 41 can be less than thread-protected tube 50 and the frictional resistance between level bat line 41 of clapping line hole 11 through other.Therefore, the level bat line 41 of clapping line hole 11 through level is easier to move, and impacts when the interior longitudinal tip side of described frame 10 region, and the deflection of clapping line 40 is larger, and can further improve repulsive force.In other words, can expand more for certain the optimum batting point of described frame 10 interior longitudinal tip side.

In addition, adopt racket 1, compare longitudinal rear end side region, described frame 10 longitudinal tip side regions are shorter in the length of width.Adopt this racket 1, clap line 41 have shorter mobile range than clapping line 41 through the level in longitudinal rear end side region through the level in described frame 10 longitudinal tip side regions, therefore, the racket 1 of this embodiment becomes more effective.In addition, can to have the top of taper shape and described frame 10 be flat to described racket 1.Adopt this racket 1, the normal angled θ 2 that is arranged on the top of described frame 10 and the bat line hole 11 of both sides is relatively large, and in the motion that the level of the inner peripheral surface 10a of described frame 10 is clapped line 41, be easy to restrictedly, therefore, the racket 1 of this embodiment becomes more effective.

Above-described embodiment is for the ease of understanding of the present invention, rather than limits by any way the present invention.The present invention can be out of shape and improve certainly, and can not depart from the scope of the present invention, and need not query, and the present invention includes its equivalents.

For example, in the above-described embodiments, using the example of badminton racquet as racket of the present invention.But the present invention is not limited to this.For example, the present invention can be applied to tennis racket, squash racket etc.And, in the above-described embodiments, using and have at the racket 1 of the bat line 40 of frame 10 interior tensions as according to the example of racket of the present invention, still, the present invention is not limited to this, not necessarily must have the bat line 40 of tension in this racket.
