In order to improve flying quality, usually changing the rigidity of material, or adopting a kind of method using air drag to receive during flying.Usually, if improve rigidity (using the material of high rigidity), weight also can increase.When weight increases, the weight balancing of whole shuttlecock is deteriorated, thus the penalty after impact during flight.Therefore, in the present embodiment, air drag is used to improve flying quality.Then, in the following embodiments, when substantially not increasing or reducing weight, air drag is increased.Particularly, flying quality is improved by the structure on the top of improving the accessory pinna part being subject to air drag impact during flying.
===first embodiment===
Fig. 5 is the perspective view of the structure of artificial feather 20 in displaying first embodiment.Further, Fig. 6 is the viewgraph of cross-section along A-A line in Fig. 5.The artificial feather 20 of described first embodiment has accessory pinna part 22 and pinna rachis part 24.Accessory pinna part 12 respectively in corresponding comparative example of described accessory pinna part 22 and pinna rachis part 24 and pinna rachis part 14, and formed by the integration of dual-color forming method.But the pinna rachis part 24 of the first embodiment is not set as the upper end (top) reaching described accessory pinna part 22.In other words, accessory pinna part 22 has not by the part of pinna rachis restriction, and described part is on the upside (tip side of pinna rachis bearing of trend) of the pinna rachis end 241 of described pinna rachis part 24.Because its accessory pinna of ratio of rigidity of the pinna rachis of the shuttlecock of natural feather is higher, so its pinna rachis part 24 of ratio of rigidity of the accessory pinna part 22 of artificial badminton ball is lower.
Further, described accessory pinna part 22 has flank 22a.Flank 22a is formed by the material identical with accessory pinna part 22, and provides by this way: give prominence to from the part of the upside of the pinna rachis end 241 of accessory pinna part 22 with convex in the extension of the pinna rachis of pinna rachis part 24.That is, artificial feather 20 has a kind of structure, wherein, forms the flank 22a of accessory pinna part 22 in the part in the upper end side of described accessory pinna part 22, instead of the pinna rachis of pinna rachis part 24.
In the artificial feather 10 of comparative example, pinna rachis part 14 is set as the upper end reaching accessory pinna part 12.Therefore, on the bearing of trend of the pinna rachis of described pinna rachis part 14, the motion of accessory pinna part 12 is subject to the restriction of described pinna rachis part 14.On the other hand, artificial feather 20 has the part of upper end (top) side in accessory pinna part 22, and described part is not by the restriction of the pinna rachis of pinna rachis part 24.Further, the flank 22a be located in described part is formed by the material (resin) identical with described accessory pinna part 22.That is, on the normal to a surface direction of described accessory pinna part 22, the part of the accessory pinna part 22 on pinna rachis end 241 is easier than other parts to be bent.Therefore, because upper end (top) side of described accessory pinna part 22 does not limit by the pinna rachis of pinna rachis part 24, so compared with comparative example, the part on the upside of pinna rachis is easy to freely move during flying.
Fig. 7 is the view of the position of the pinna rachis end 241 explaining pinna rachis part 24.As Fig. 1 and Fig. 2 explain, when artificial feather 20 is applied to artificial badminton ball 1, each described artificial feather 20 (accessory pinna part 22) is with the artificial feather 20(accessory pinna part 22 adjacent with another) overlapping (having the dash area of oblique line in Fig. 7) such mode arranges.In the present embodiment, as shown in Figure 7, the pinna rachis end 241 of pinna rachis part 24 is in the upside (tip side) of the part (hereinafter also referred to lap) relative to described overlap.
This is because if described pinna rachis end 241 is in the downside of lap, be easy to a kind of phenomenon occurs: when impacting shuttlecock, the overlap condition of adjacent accessory pinna part 22 can reverse when impacting.As shown in FIG., the position of described pinna rachis end 241 is arranged on the upside of the lap relative to adjacent accessory pinna part 22, therefore, can suppress by the generation of intersection (wherein, adjacent blade-section reverses).
As mentioned above, the artificial feather 20 of the present embodiment comprises the accessory pinna part 22 of sheet and pinna rachis part 24, and in described pinna rachis part 24, pinna rachis end 242 is fixed to bottom 2 to support described accessory pinna part 22.Described accessory pinna part 22 has bearing of trend at pinna rachis relative to the pinna rachis end 241 of pinna rachis part 24 in the part of the tip side of described accessory pinna part 22, described part, and forms flank 22a in the part..
In this manner, in artificial feather 20, due to the restriction of tip side not by pinna rachis during flying of described accessory pinna part 22, compared with the artificial feather 10 in comparative example, described artificial feather 20 is easy to more freely move.Therefore, by described artificial feather 20 being applied to artificial badminton ball 1, the air drag during flight can be improved, thus flying quality can be improved.
Should be noted, all 16 accessory pinnas of artificial badminton ball 1 all can adopt artificial feather 20, or can use described artificial feather 10 and artificial feather 20.Such as, several feathers in 16 artificial feathers 10 of the artificial badminton ball 1 in Fig. 1 with Fig. 2 interchangeable become artificial feather 20.
The change case of the first embodiment

Figure 12 A to Figure 12 D is the explanatory schematic diagram of the structure of artificial feather 50 in displaying the 4th embodiment.Described artificial feather 50 comprises accessory pinna part 52, pinna rachis part 54, and flank 52a.Should be noted, accessory pinna part 22, pinna rachis part 24, pinna rachis end 241 and flank 22a in corresponding first embodiment of described accessory pinna part 52, described pinna rachis part 54, pinna rachis end 541 and described flank 52a difference, also have the structure similar with the first embodiment.Therefore, the description to it is omitted.
Artificial feather 50 in Figure 12 A has slit 521 in accessory pinna part 52.The part of the described accessory pinna part 52 of slit 521 in the tip side of the pinna rachis end 541 relative to pinna rachis part 54 is formed with V-arrangement.By providing such slit 521, be not subject to the restriction of pinna rachis relative to the part in the outside (right side in figure) of the slit 521 of pinna rachis.Therefore, this part can freely be moved.Therefore, by described artificial feather 50 is applied to artificial badminton ball 1, can air drag be improved, thus can flying quality be improved.Should be noted, preferably, the upper end of described slit 521 is positioned at the upside (tip side) relative to the lap of described accessory pinna part 52.It is further preferred that the bottom of described slit 521 is also positioned at the upside (tip side) relative to the lap of described accessory pinna part 52.In this manner, the generation of intersection (adjacent blade-section reversion) can be suppressed.
Should be noted, preferably, the forming position of described slit 521 is the position in the downstream of the direction of rotation being equivalent to artificial badminton ball 1.Further, in fig. 12, an accessory pinna part 52 is only formed a slit 521, but is not limited only to this, also can form multiple slit.Such as, described slit can be arranged on the opposition side (left side in figure) relative to pinna rachis.
The artificial feather 50 of Figure 12 B has slit 522 in accessory pinna part 52.Described slit 522 is formed along straight line in part in the tip side of the pinna rachis end 541 relative to pinna rachis 54 of the bearing of trend of pinna rachis.Further, the artificial feather 50 in Figure 12 C has slit 523 in accessory pinna part 52.In the part of described slit 523 in the tip side of the pinna rachis end 541 relative to pinna rachis 54, on the incline direction of the bearing of trend relative to pinna rachis, straight line is formed.
Should be noted that therefore similar due to the forming position of described slit 522 and described slit 523 and number thereof and above-mentioned slit 521 omit the description to it.In these cases, by these artificial feathers are applied to artificial badminton ball 1, also can improve air drag, thus can flying quality be improved.
Should be noted, when each slit (slit 521,522,523) that such as Figure 12 A to 12C provides, pressure easily concentrates on the end (bottom) of each slit, and is easy to tear accessory pinna part in this part.Therefore, stick together preferably by two sheet members and form accessory pinna part 52, as the second embodiment.Further, preferably, supatex fabric and foam sheet component are used for described two sheet members.If two foam sheet components stick together, due to low tearing strength, may rupture when impulsive force.
Artificial feather 50 in Figure 12 D has protuberance 524 in accessory pinna part 52.Protuberance 524 is roughly triangle, upwardly projecting from the top of described accessory pinna part 52.Described protuberance 524 can freely-movable and not by the restriction of described pinna rachis part 54.Should be noted, in the drawings, an accessory pinna part 52 is only formed a protuberance 524, but be not limited in this, multiple protuberance can be formed.Such as, described protuberance 524 also can be arranged on the opposition side (left side in figure) relative to pinna rachis part 54.In this manner, by the artificial feather 50 being provided with protuberance 524 is applied to artificial badminton ball 1, can air drag be improved, thus can flying quality be improved.Should be noted, the shape of described protuberance 524 is not limited to triangle.Such as, the shape of described protuberance 524 can be semicircle or trapezoidal.
